The root 3B of bar 3 inserts the supporting part 9 of main body 5 slidably, keeps sealing between the inner surface of root 3B and supporting part 9 so that make.Supporting part 9 has a groove 10 axially to stretch at the outer surface of supporting part 9.An outer surface protrusion of operating protrusion 11 from the root 3B of bar 3.Protrusion 11 is to be slidably engagement with groove 10, to avoid bar 3 around its rotation.On the operation protrusion 11 a coarse non skid matting 11A is arranged, slip off thereon with the thumb that prevents the user.Protrusion 11 and groove 10 have formed anti-rotation device.Aspirating mechanism 4 has an operation pipe 12, integrally constitutes a valve part 15 at the outer surface of managing 12.Valve partly 15 has leading edge 15A and trailing edge 15B respectively, and the effect of leading edge portion 15A is to prevent that air and the addle slipper by supporting part 9 from entering and infiltrate in the main body 5, and trailing edge partly the effect of 15B be to prevent that material from spilling.When pipe 12 was in the normal position, the front surface of valve part 15 was suitable for supporting the protrusion 30 that provides on the inner surface of the main body 5 that is loaded on handle 2.

The root 3B that the previous section of pipe 12 is inserted in bar 3 goes up in the hole 31 that forms.Accommodate an anterior valve body 19 in the front of pipe 12, the shape of this valve body shows in Fig. 8 and 9.Valve body 19 is to be made by the elastomeric material of for example synthetic resin and so on.And valve body 19 also has two

valve block

19A and 19B, and is outer respectively in its front-end and back-end.Valve block 19A is normally circular, and its peripheral portions is cut into four passage 19D that allow material pass through.Another valve block 19B identical with valve block 19A shape also has four passage 19D.Two

valve block

19A and 19B interconnect by an annular section 19C who mainly plays the elastomeric element effect.

Be contained in valve body 19 in the hole 31 be in before the valve peripheral part that passes 19A be supported on by on the step 3C that forms on 31 inner surfaces of hole.

The leading section of operation pipe 12 has a collar flange 12A, this edge and back valve block 19B engagement.Pipe 12 is loaded in the join domain of the root 3B of bar 3 and main body 5, and has a conduit 32 vertically to pass along it, so that material 24 is delivered to bar 3 from the suction chamber 21 of a sealing.Suction chamber 21 is in the valve part 15 of pipe 12 and is fixed between the valve base part 16 of main body 5 rear ends and forms.A spherical rear valve body 20 is provided in the valve base part 16.Rear valve body 20 is steels.An action bars 22 freely is provided in conduit 32, has been used for controlling moving of front valve shell 19 and rear valve body 20.Valve base part 16 is cup-shaped, and a SS 18 is arranged at its bottom.On the inwall of valve base part 16, be provided with a plurality of flange 16B.Flange 16B is configured on the circumferencial direction of valve base part 16 to give fixed distance.Flange 16B forms a space 33, is used for holding rear valve body 20, and the front end of each flange 16B has a ridge 16C, drops out from space 33 to prevent valve body 20.

The latter half of operation pipe 12 extend into suction chamber 21.Be used for the compression helical spring 17 of pipe 12 before pushing to, be placed between the inboard of the anterior face of flange 16B and bell-shaped valve door section 15, the latter half of pipe 12 then inserts in the helical spring 17.

Above-mentioned action bars 22 is enough thin, be not enough to stop material 24 from managed 12 conduit 32, to pass through, and having as shown in Figure 3 valve body 19 to close conduit 32 and valve body 20 has been closed under the situation of SS 18, its length is shorter slightly than the distance between two

valve bodies

19 and 20.

In the bottom of container 6, the movable pedestal 23 of a piston sample is housed, this base is axially with the inner periphery surface of container 6 and closely contacts slidably.Movable pedestal 23 is to be made by soft synthetic resin or other similar material, and two sliding

edge

23B and 23C are arranged, expand in the front-end and back-end of cylindrical portions may 23A respectively one bell.Sliding edge 23B closely contacts with the inner peripheral wall of container 6 with 23C, has guaranteed sealing, so that the emulsion-like material or the fluent material 24 that are filled in the container 6 can not spill from the inside.

At the front end of cylindrical portions may 23A, a cylindrical portions may 23D that diameter is less is arranged, can be inserted among the less ledge 6B of the diameter of container 6 porch, therefore all materials fully can be used up.The base plate of being pointed out by label 25 is for preventing that moveable base 23 from deviating from from the rear end of container 6 in the drawings.On the periphery surface of the rear end that base plate 25 insertion containers 6 open wide.Meanwhile, base plate 25 plays a reinforcement, to prevent owing to external force makes container deformation, so that make sliding edge 23B keep closely contacting with the inside of container 6 with 23C.At the center of base plate 25 an outstanding bar 25A is arranged, extend among the cylindrical shape part 23D of base 23, move backward to stop base 23.Have a plurality of air duct 25B on the base plate 25, be used to prevent during using brush 1, produce negative pressure owing to moving forward of base 23 makes a back space 34 that is limited between base 23 and the base plate 25.

The operation of brush 1 will be described with reference to figure 3 to 7.

Be held in a handle 2 in the hand and be in state shown in Figure 3.When brush is used, by by the bar 3 that is implanted with hair being pushed to the back or pushed container 6 to, be pressed onto on the something with the tip of another hand propelled bar 3 or the tip by barre 3 at the thumb of operation on the protrusion 11.As shown in Figure 4, the rear portion of bar 3 is pushed into handle 2 along supporting part 9, and operation pipe 12 is pushed in handle main body 5 simultaneously.

When bar 3 was pushed into handle 2 as shown in Figure 4, operation pipe 12 was shifted to the back, and the front end of action bars 22 pushes up valve block 19B, make valve body 19 compression or be extruded, therefore the open front of conduit 32 is opened, and rear valve body 20 is pushed up in the rear end of bar, thereby closely closes SS 18.

Bar 3 is broken away from the pushing state then, if because the repulsive force of compression spring 17, barre 3 and pipe 12 back into their anterior locations separately.At this moment, it is negative that pressure in the suction chamber 21 of main body 5 becomes, and the result, the material 24 in the container 6 is by valve base part 16(Fig. 5) on SS 18 be pumped into the suction chamber 21 of main body 5.

When valve body part 15 during to front slide, anterior lip part 15A is forced to radial dilatation, makes the inwall of itself and main body 5 obtain closely to contact.In addition, front valve shell 19 has been closed conduit 32, therefore, is under the negative pressure condition in suction chamber, and the gap of the slipper that air and addle can be by supporting parts 9 enters or infiltrates its inside.Suction causes the negative pressure in the container 6, and movable pedestal 23 is closely contacted before the direction that reduces the distance and then with the inner round wall of container 6.

When bar 3 was pushed to the back as mentioned above once more, current front valve shell 19 was opened the conduit 32 of pipe 12, the SS 18 on the rear valve body 20 shut off valve base members 16.Sucked material in the suction chamber 21 and be admitted to material passage 8(Fig. 6 in hole 31 and the bar 3).After this, bar 3 is broken away from the pushing state, and the material 24 in suction chamber 21 stops to flow forward, and the material in the container 6 is drawn into suction chamber 21(Fig. 7 of main body 5).With above-mentioned same, this suction causes that the removable base 23 in the container 6 moves forward with the soakage of material 24.

When first use brush, this operation will repeat two or three times just can make material 24 be full of main body 5, conduit 32 and material passage 8.After this, whenever push away bar 3 No. one time, just have the quantitative material 24 of suitable once-through operation to be added on the surperficial 3A that is implanted with hair.Like this, brush 1 has been ready to and can have used.Clearly, if it is not enough to be added to the amount of the material 24 on the surperficial 3A, will push away twice or more times.

After the material in the container 6 24 uses up, can unload container 6 down from the rear end of main body 5, one from external screw thread 6A screw off lid on the new container 6 (not shown) unload, and the external screw thread 6A of new container is screwed on the internal thread 5A of main body 5.Brush 1 just can continue to have used immediately again so.Material passage 8 openings of opening on the surperficial 3A that is implanted with hair at bar 3 may become dry between the operating period continuously, so the whole part 7 that is implanted with hair can be with a lid 26 covers, shown in Fig. 1 dotted line.

In the present invention, action bars 22 is housed between the front and

back valve body

19 and 20, to control the switch motion of two valve bodies 19 and 20.Bar 22 can guarantee that two valve bodies alternately move reliably, shown in Fig. 4 to 7.In addition, if the length of adjusting rod 22 suitably just can be guaranteed necessary material 24 supplys are added to surperficial 3A.

And because valve body 19 is the elasticity valve members that can compress and expand, a special helical spring valve body being pushed to pipe 12 front openings has not just needed, thereby has simplified the frame for movement of valve means.

As mentioned above, brush of the present invention comprises the bar 3 that is implanted with hair with operation protrusion 11, pushes main body 5 to by barre 3, can deliver to a certain amount of material 24 on the surperficial 3A that is implanted with hair.This is good, because can only just can use this brush with operation once.In addition, owing to push away a bar 3 and provide one to give quantitative material, the user needn't resemble to go to note how many materials once-through operation need extrude the operation in the past, also can avoid using too much material and causes waste.In addition, material 24 is supplied with by catch bar 3 simply.Therefore, when brush uses as toothbrush, even child and children also can easily use this brush 1.In addition, containers 6 is easy to unload down and throw aside from main body 5, and the main body 5 of brush can be used one section long time economically.

Especially in brush 1 of the present invention, when bar 3 was pushed to the back and material 24 fed to bar 3, moveable base 23 moved forward with the minimizing of material 24 in the container 6.This sucks and enters in the material 24 container 6 from the outside with regard to having prevented air fully.From the health angle, material can be supplied with under the state of sealing fully, and this also is desirable.With comparing of other, brush 1 of the present invention comprises a spot of parts and is easy to be made.

In the above-described embodiments, for coating material 24, be implanted with a large amount of thin or thick bristles at the head of bar 3.Yet also can be, and use a slice sponge material without bristle, the head that a slice rubber or the member with convex-concave surface are linked bar 3 comes coating material 24.
