Waterpik Water Flosser WP-‐100

Daniel Verbin TWR2000 Project 1

1. General description

The Waterpik Water Flosser WP-‐100 is a lightweight, portable dental cleaning device that uses a stream of pulsating water to irrigate the gumline and clean in between the teeth in order to remove plaque. It is an easy to use and more effective alternative to traditional Glossing and is especially useful for people with braces, bridges and crowns. It is an excellent option for people who are unable to use dental Gloss. It is clinically

proven to be up to 50 percent more efGicient than dental Gloss. The device is commonly available for purchase from drug stores, department stores, dental ofGices, and major online retailers. It retails for $59.99 and comes with a three-‐year warranty.

The WP-‐100 is portable and easily rests on your bathroom counter or on a shelf. It is constructed of hard plastic and uses a wand with a Glexible tip to spray a stream of water onto your gumline and in between your teeth. The wand is attached by a Glexible chord to the base. The base contains an on/off switch and a pressure control dial. The inside of the bases houses a motor and a pump. A water reservoir with a removable cover sits atop the base. Water travels from the reservoir to the base through a reservoir valve. It then travels through a chord into the wand where it pulsates out of the snap-‐in tip (see Figure 1).

The WP-‐100 comes with six different tips – two classic jet tips, one plaque seeker tip, one orthodontic tip, one pickpocket tip and one toothbrush tip. The tip snaps into the wand through a spring-‐loaded detent. It swivels 360 degrees using a circular adjustment at the top of the wand. The chord on the wand neatly curls into a storage slot in the side of the base (see Figure 2).

Figure 1 Figure 2

The WP-‐100 measures:

• 13 cm in length

• 14 cm in width

• 19 cm in height, including the water reservoir

• 6.9 cm in height, the base minus the reservoir

2. Description of the main parts

The water reservoir sits snugly on top of the base. The lid snaps onto the reservoir. The wand is connected to the base by a chord. The tip snaps into the wand through a spring-‐loaded detent that allows it to swivel 360 degrees for optimal water Glossing control. There are O-‐ring seals between each main part to prevent water leakage.

Main parts (see Figure 3):

(2.1) The base

(2.2) The water reservoir

(2.3) The wand/tip

2.1 The base

The base is made of hard white plastic designed with an aesthetically pleasing curved shape.

The on/off switch is an oblong shaped rocker switch that abuts from the side of the base below the reservoir.

The pressure control dial is located below the on/off switch, near the bottom of the base. It is composed of a plastic circular dial inside a plastic ring.

Figure 4

2.1.1 The motor and pumpThe motor is a simple single-‐phase synchronous induction motor. The motor is powered by alternating current sent through the power chord. This type of motor runs well at a constant speed. It also allows you to smoothly vary the speed.

The motor powers the pump. The pump is a reciprocating piston design. A reciprocating piston pump uses multiple reciprocating pistons to create a rotating pressure.

The pump sucks water from the reservoir through the reservoir valve. The water is forced through the wand and out of the tip as a pulsing stream of water.

Parts of the base (see Figure 4):

(2.1.1) The motor and pump

(2.1.2) The on/off switch

(2.1.3) The pressure control dial

(2.1.4) The power cord

2.1.2 The on/off switchThe on/off switch is an oblong rocker switch on the side of the base that measures 3 cm x 1.5 cm. When the switch is in the “on” position, the motor turns on activating the pump, which forces water through the wand and out of the tip (see Figure 5).

2.1.3 The pressure control dialThe pressure control dial is a circular dial surrounded by a grey plastic ring that has a diameter of 4.5 cm.

It varies the speed of the motor/pump from 1 to 10. You change the speed by rotating the handle inside the dial (see Figure 5).

2.1.4 The power cordThe power cord is attached to the base. It provides the alternating current (AC) that powers the motor. The cord is white and measures 135 cm.

2.2 The water reservoir

2.2.1 Water reservoirThe water reservoir measures 9 cm x 14.8 cm x 8.4 cm. It is transparent and made of plastic. It holds up to 600 ml of water (see Figure 6).

When the reservoir is placed onto the base’s 3 cm deep indent, its plunger seal is pushed up and the water is released into the base. This allows water to Glow into the pump (see Figure 7).

2.2.2 Water reservoir coverA plastic reservoir cover that is 3.1 cm tall Gits snuggly onto the water reservoir using grooves. The cover is composed of a grey plastic base and a white plastic top attached together by a three-‐connection plastic hinge (see Figure 6).

The cover opens up using the hinge. On the inside of the base of the cover there are four plastic pairs of grips for storing four tips. The grips alternate back to front so that the tips will not accidentally touch each other. This keeps the tips sanitary (see Figure 8).

2.3 The wand and tip

2.3.1 The wand

The wand is made of white plastic and measures 10.6 cm x 2.8 cm. The wand is attached to the base via a curled plastic tube that is 33.5 cm long when extended. The tube curls into a storage opening at the bottom of the base (see Figure 9). The slot has a diameter of 5.3 cm.

Water Glows from the reservoir through this tube. It goes into the wand, where it pulsates out of the tip.

2.3.1.1 The tip eject buttonThe tip eject button is located near the top of the wand. It measures 1.3 cm x 0.3 cm. It is grey and made of plastic. When you press it, the tip ejects from the wand (see Figure 9).

2.3.1.2 The pause buttonThe pause button is a round grey button located in the middle of the wand. It measures 2 cm x 1.6 cm. When pressed down, the pause button stops the Glow of water pulsating out of the tip (see Figure 10).

2.3.1.3 The tip rotator knobThe tip rotator knob is located at the top of the wand. It is made out of white plastic moulded into serrated bumps. It has a diameter of 2.5 cm with a 1.2 cm diameter hole that the tip locks into. When you spin the knob, the tip rotates. The tip rotates 360 degrees (see Figure 10).

Figure 10

2.3.2 The tipThe Waterpik Water Flosser WP-‐100 comes with six tips: two classic jet tips, one plaque seeker tip, one orthodontic tip, one pickpocket tip and one toothbrush tip. The press-‐in tip snaps into the wand through a spring-‐loaded detent. There is an O-‐ring seal in the wand that stops water from leaking. Each tip measures 10.7 cm outside of the wand and 7.5 cm when locked into the wand.

The tip has a 12-‐sided polygon-‐shaped key. This key locks the tip into the wand so that it does not rotate while in use (see Figure 10).

2.3.3 The wand storage clipThe wand storage clip is white and is made of plastic. It measures 4 cm x 3.1 cm. It is located on the side of the base above the power cord storage slot. The wand Gits into the storage clip for safe storage when not in use. The cord attached to the wand curls underneath the storage clip inside the cord storage slot (see Figure 9).



3. Cycle of OperationThe Waterpik Water Flosser WP-‐100 is simple to use.

Once you learn how to clean your teeth with the tip, which takes a little practice, it is as easy as traditional Glossing.

There are several procedures to follow when using the WP-‐100:

3.1 Inserting the tipBefore using the WP-‐100, the tip must be locked into the wand and the wand must be removed from the storage clip. To insert the tip, place it in the centre of the knob at the top of the wand. Make sure the coloured ring is Glush with the end of the wand. Lock the tip into place.

3.2 Filling the water reservoirTo Gill the water reservoir with water, remove the reservoir from the base, remove the lid from the reservoir and Gill the reservoir with lukewarm water. Return the reservoir to the base and press down Girmly. Put the lid back on.

3.3 Setting the pressure control dialIf you are using a water Glosser for the Girst time or if you have sensitive gums then you should begin with the pressure control dial on 1. Otherwise, slowly increase the pressure control by small increments until it is at a level that is appropriate for your gums. Most people do not need to set it very high to achieve a comfortable water Glossing experience that results in clean teeth.

After the dial is set, turn on the machine while holding down the pause button on the wand so that water does not spray out of the tip.

3.4 Cleaning your teethThe recommended technique for water Glossing with the Waterpik WP-‐100 is to place the wand so that the tip is at a 90-‐degree angle from your gumline.

Remember: If you need to temporarily stop, you can press the pause button on the wand.

To water Wloss your teeth follow these steps:

3.5 Emptying the water reservoirWhen you are Winished water Wlossing follow these steps:

Step 1. Lean over the sink.

Step 2. Place the tip in your mouth near the gumline and let go of the pause button.

—You can direct the stream by turning the tip rotator knob.

Step 3. Close your lips so that water does not splash but leave them parted enough for excess water to drip from your mouth into the sink.

Step 4. Glide the tip along the gumline, starting with your molars and slowly moving toward your front teeth.

—Be sure to stop between each tooth to allow the water to dissipate.

Step 6. Continue along the gumline until you have cleaned the inside and outside gums of all your upper and lower teeth.

Step 1. Turn off the unit using the on/off switch.

Step 2. Place the wand back in the clip.

Step 3. Unplug the water Glosser.

Step 4. Take the lid off the reservoir, and remove the reservoir from the base.

Step 5. Empty any remaining water into the sink.

Step 6. Place the empty reservoir back on the base.

Step 7. Store the WP-‐100 in an upright position until your next use.
