Description

The hydraulic-driven toothbrush

Technical field

This utility model relates to a kind of toothbrush.

Background technology

For keeping oral cavity cleaning, dental health, reduction oral cavity sickness rate, we will adhere to brushing teeth every day, cleaning oral cavity.Traditional toothbrush is that the action of armrest moves up and down toothbrush, and bristle is removed the food debris in dental surface or the teeth space.Manual toothbrush armrest control toothbrush is up and down, really obtains cleaning in order to guarantee tooth, and the frequency of brushing teeth also has certain requirements, and the posture of toothbrushing person also must standard.But if will guarantee to brush teeth by the posture of standard, people often feel too to require great effort, and it is uninteresting that palikinesia is made us feeling, child Geng Chang produces brushing teeth and resists emotion, is difficult to persevere.

And electric toothbrush has replaced traditional manual mode with powered version, and the frequency of exposure of bristle and tooth is many, frequency is fast, can effectively clean the gingiva tooth, and the process of brushing teeth is become easily, and the child also more takes like a shot, and brushes teeth and no longer thinks kind of a burden.Therefore electric toothbrush more and more is subjected to the welcome of user.Be illustrated in figure 1 as a kind of electric toothbrush of magnetic charging, it as power, drives micro-machine 30 by rechargeable battery 20 with battery, and the rotation of machine shaft makes the bristle quick rotation of toothbrush by the transmission of change-speed gearing group.Electric toothbrush needs driven by power, mainly is rechargeable battery or common batteries, and along with popularizing of electric toothbrush, its use amount has increased, and the use amount of battery also greatly increases, and environmental pollution has been increased.In the face of more and more serious environmental pollution problem, the appearance of electric toothbrush allows the people half downcast and half glad really.

Summary of the invention

The purpose of this utility model is to provide a kind of new power-actuated toothbrush.

Hydraulic-driven toothbrush of the present utility model comprises brush holder, brush, the bristle of hollow, it is characterized in that: also comprise a hydraulic drive mechanism, be placed in the brush holder chamber, and being communicated with inlet and the liquid outlet that is opened in brush handle shell, the output shaft of described hydraulic drive mechanism drives bristle by drive mechanism and rotates.

This utility model, drives toothbrush bristle and rotates as power source with highly pressurised liquid, compares with electric toothbrush, need not use electric energy.During use, only need high-pressure water pipe is inserted the toothbrush water inlet, utilize the pressure of tap water to promote the hydroturbine rotation, and bristle is rotated by the transmission of change-speed gearing group.This utility model adopts many group worm and gear groups to realize break-in, the deceleration transmission of power.Worm gear, worm-drive have the big advantage of gear ratio, and during transmission, worm screw is revolved and turns around, and worm gear only turns over one or two tooth.Worm and wormwheel can be used for intersecting the big moving of two between centers, and this utility model has adopted two pairs of worm and wormwheel groups to carry out transmission, and is structurally very compact, saved the space, reduced the volume of toothbrush.Head toothbrushes adopts a worm screw and six worm gear engaged transmission, and plurality of bristles is rotated simultaneously, designs ingenious.Toothbrush head is provided with water jet, can make the water ejection by the gauge tap that touches on the handle, so this utility model both can satisfy the needs of brushing teeth, and also can satisfy the needs of gargling, and kills two birds with one stone, and is easy to use.But this utility model is energy savings both, can reduce environmental pollution again, is a kind of new power energy resource toothbrush that is worthy to be popularized.

The specific embodiment

As Fig. 2, shown in Figure 3, the hydraulic-driven toothbrush comprises brush holder 1, brush 2, bristle 3.Bristle 3 is fixed on the brush 2, offers water jet 21 on the brush 2.Brush holder 1 afterbody is provided with inlet 11 and liquid outlet 12.Brush holder 1 inner hollow, and capped 13 be separated into upper and lower chamber, capping 13 is provided with the passage that is communicated with two Room, and by the connection or the cut-out of valve 5 these connections of control.Upper chamber is communicated to brush.Bottom chamber is being settled hydraulic drive mechanism and change-speed gearing group, and both separate with capping 14.

Valve 5 is made up of ball cushion rubber and push rod 51.When being ready (OFF), push rod 51 pushes away in forefront, and ball 52 is clogged the fluid passage inlet in capping 13, has blocked the connection between the upper and lower chamber.At this moment, upper chamber and lower chambers are two independent cavity separately, are not communicated with mutually.To pusher, ball 52 promptly leaves O-ring seal push rod 51, and at this moment, upper chamber and lower chambers are communicated with.

In the present embodiment, hydraulic drive mechanism is a hydroturbine 4, as shown in Figure 4, comprises casing 42, blade 43, main shaft 41.Offer tangential water inlet 44 on the casing 42, and have discharge outlet 45, be connected with the liquid outlet 12 of brush holder afterbody.

As shown in Figure 5, drive mechanism comprises two pairs of worm and gear change-speed gearing groups of installing in lower chambers, installs handle main shaft 8, handle main shaft 9 and bristle driving gear set in upper chamber.Worm screw 71 is installed on the shaft extension end of hydroturbine main shaft 41, and worm gear 72 is engaged in worm screw 71.Worm screw 73 and 72 coaxial connections of worm gear, worm gear 74 is engaged in worm screw 73, and installs the shaft extension end in handle main shaft 8.Because the compact conformation of worm screw, worm gear, and gear ratio is big, and this drive mechanism is reaching significant deceleration effect simultaneously, and it is little to take up room, and has reduced the volume of handle.

Handle main shaft 8 is socketed on handle main shaft 9.The shaft extension end socket worm screw 75 of handle main shaft 9, worm screw 75 and six worm gears 76 mesh respectively.Fix a branch of bristle respectively on each worm gear 76.

Now in conjunction with the accompanying

drawings

2,3, work process of the present utility model is further described:

Water under high pressure flows in the brush holder lower chambers from inlet 11, riddles in the whole chamber.Water under high pressure flows in the turbine through the water inlet 44 of turbine 4.Under the effect of current, turbo blade 43 rotates, and main shaft 41 is rotated.Water is then flowed out outside the toothbrush through drain pipe 12 by the outlet on the turbine shell 45.Effusive water can insert return duct, further reclaims and uses.

Main shaft 41 rotates, and worm screw 71 is rotated, and rotates thereby drive with worm gear 72 break-ins and the deceleration of its engagement.Worm screw 73 is rotated with the main shaft of worm gear 72, and drives worm gear 74 rotations, realizes break-in and deceleration again.Handle main shaft 8 rotates with worm gear 74, and handle main shaft 9 is rotated.Worm screw 75 is rotated with handle 9, and 6 worm gears 76 with its engagement are rotated, thereby has realized the rotation of bristle.

When brushing teeth, valve 5 is closed condition, and promptly push rod 51 is in foremost, and ball 52 is jammed in the fluid passage inlet of capping 13, and upper and lower chamber is isolated fully, and the water of lower chambers can't flow in the upper chamber.When push rod 51 during to pusher, valve promptly is opened, and ball 52 advances backward, and water flows in the upper chamber through the fluid passage of capping 13, flows to head toothbrushes, and from water jet 21 ejections of brush.And the water that flows to turbine 4 does not change, and still can promote turbine work and flows out from return pipe.As from the foregoing, rinse is two independently functions with brushing teeth, and user can make water pour the oral cavity when brushing teeth, and washes away the dirt in the oral cavity.Because the water that flows to head toothbrushes through valve 5 is the sub-fraction of total flow, current mainly still are utilized as power, and then recycling, can too not run off and cause waste.
