A compressed air cavity (18) which is divided by a toothpaste plunger (4) is arranged in the toothbrush handle (3); one end of the compressed air cavity (18) is connected with a pressurized cylinder (6) and a blocking sheet (5) with a one way valve (11). A pressurized plunger (8) with an air in/out hole (9) and a release spring (7) are arranged in the pressurized cylinder (6). The toothbrush can be used for staying at home or travelling.

Description

Toothbrush with toothpaste

The utility model be belong to a kind of with gas pressure promote toothpaste piston and the family expenses of forming by head toothbrushes, toothbrush handles, toothpaste piston, supercharging cylinder, charged piston etc., the Sanitary toothbrush of travelling.

Similar toothbrush before the utility model can reduce according to the principle of squeezing toothpaste out of a tube: (one) thus directly promoting the toothpaste piston with firmware components extrudes toothpaste; (2) making it distortion with the flexible plastic toothpaste bag by the squeezing toothpaste bag reduces bag chamber volume and comes toothpaste is extruded.Thereby the utility model then is to promote the toothpaste piston with gas pressure toothpaste is extruded.

If with first kind of principle.Existing similar toothbrush just must be set up corresponding power transmission, the application of force, other part.As spring, screw mandrel, turn-knob, also just increased some corresponding cooperations simultaneously and paid.Thereby make total processing technology complexity, processing order increases, and under the certain situation of appearance and size, has influenced the toothpaste cavity volume, thereby reduces the access times that once inject toothpaste.Existing similar toothbrush is that the toothpaste cavity piston is extracted out when injecting toothpaste.Inject toothpaste then, so very aspect not is also unhygienic.

If with second kind of principle, for making toothbrush time spent not, avoid toothpaste to extrude, just must set up some corresponding soft bag hard coats and some switches part in addition, other part is pushed in the also increase that has, overall structure processing technology complexity that this just equally also makes.Part in addition, operation increases, and also has quite a few toothpaste to squeeze not to come out in addition, has also influenced the access times that once inject toothpaste.

More than can be respectively from the number of patent application and the day for announcing (85.2.03506,1986.4.30), (85.2.02842,1986.10.8), (85.2.04780,1986.12.24), (86.200106,1987.4.22), (86.2.07937,1987.7.1) the middle analysis draws.

The purpose of this utility model mainly is in order to overcome the above-mentioned shortcoming of existing similar toothbrush on the one hand, the advantage that keeps existing similar toothbrush on the other hand again, simultaneously also be to be promoting the use of of toothpaste in bulk from now on, a kind of supporting family expenses, tourism Sanitary toothbrush of adorning toothpaste is provided.In order to achieve the above object.The utility model adopts Pascal's law technically, and the fluid in the promptly airtight visitor can the constant transmission pressure of size and boyle-Ma Lvete (PV=constant) law, the imperial equation (PV=(M)/(U) RT) of Mendeleev-carat cloth.

But the toothbrush handles (3) that the utlity model has the cavity body structure of a can toothpaste and head toothbrushes (2) are connected with internal thread on the central axis of head toothbrushes (2) a toothpaste passage (14) is arranged, toothpaste passage (14) one ends lead to bristles (16), and it is to prevent not time spent toothpaste outflow of toothbrush that the other end has its effect of unidirectional elasticity retaining tongue (13).Toothbrush handles (3) is connected with plug-in type or external screw thread with Toothbrush head cover (1) with the end that head toothbrushes (2) links to each other, and the other end is connected with supercharging cylinder (6) with internal thread.Have on the Toothbrush head cover (1) and hang folder (15) passage (17), the effect of hanging folder (15) is a usefulness when inserting pocket, and passage (17) is to be convenient to the usefulness that the water vapour of wet bristles (16) overflows, in case when day hot in the cover gaseous mixture foul and influence health.Return spring (7) is housed in the supercharging cylinder (6) and is with charged piston (8), the end that supercharging cylinder (6) is relative with toothpaste piston (4) is pressed with catch (5), charged piston (8) adopts single-ended bowl-shape soft limit self-fastening sealing structure, in case when compression gas leakage, its central axis has turnover air flue (9) so that air can smoothness enter cylinder chamber (10) during charged piston (8) return, reduces the return resistance.The check valve (11) that the center of catch (5) has a soft elastoplast that fuses with catch (5) to make, its effect are to prevent that compressed air in the compressed air cell (18) from flowing backwards and influence squeeze pressure.Toothpaste piston (4) is made single-ended or the bowl-shape soft limit of both-end self-fastening sealing structure, is nested in the toothpaste cavity (12).

Use of the present utility model and operation principle: block turnover air flue (9) with finger during use and push simultaneously, charged piston (8), when the air pressure in the cylinder inner cavity (10) during less than the air pressure in the compressed air cell (18), air in the cylinder chamber (10) is followed boyle-boyle's law, air pressure increases gradually, until greater than the air pressure in the compressed air cell (18) time, check valve (11) is opened, at this moment compressed air cell (18) communicates with cylinder chamber (10), and the pressure in compressed air cell (18) and the cylinder chamber (10) reaches balance rapidly.Continue compression charged piston (8) pressure continuation increase and promote toothpaste piston (4) until the resistance of the frictional resistance retaining tongue (13) of interior frictional resistance that overcomes toothpaste and toothpaste piston (4), thereby toothpaste is extruded, finger unclamps, cylinder chamber (10) is reduced to atmospheric pressure rapidly by turnover air flue (9) its internal gas pressure that communicates with atmosphere, air pressure in compressed air cell this moment (18) is owing to close check valve (11) rapidly greater than cylinder chamber (10), compressed-air actuated pressure is when balancing each other with other resistance, toothpaste piston (4) stop motion, toothpaste stops to extrude.Repeatedly push, charged piston (8) can obtain required amount of paste.Squeeze toothpaste and Toothbrush head cover (1) is dialled (revolving) gone out, inserted (revolving) and go into toothbrush handles (3) afterbody and can use, when injecting toothpaste head toothbrushes (2) has been screwed out pressurized cylinder (6) and unclamp, can inject toothpaste.It is replaceable when head toothbrushes (2) lost efficacy.

The utility model is compared with similar toothbrush has following advantage:

1, under the identical appearance size, the access times of disposable injection toothpaste are many, toothpaste utilization rate height.

2, part is few in addition, technology is simple, and cost is low.

3, easy to use, health, volume are little, are easy to carry.

If 4 are used with toothpaste in bulk from now on, can save a large amount of softer metals and same package material.Eliminated of the harm of soft metal skin simultaneously to human body.
