9A is pushed by the interlocking rod 22 and separated from the tube end of the actuating tube 12.

Then, when the pressure on the actuating tube 3 is released, the compression spring 17
The actuating tube 3 protrudes and returns to its original position due to the burst attack, the actuating tube 12 is also returned, and the suction chamber 21 in the handle body 5 becomes negative pressure, and the second valve element 20 is sucked up and separated from the valve seat 16. Then, the through hole 18 is opened (as shown in the fourth figure). At this time, the negative pressure in the suction chamber 21 causes the bearing hole 13 of the handle main body 5 and the base 3 of the actuating tube 3 to
Air and sewage try to be sucked in through the gap between A and A, but when the actuating tube 12 is returned to its original position by the compression spring 17, the end 15A of the valve portion 15 is tightly pressed against the inner circumferential surface of the handle body 5. and sliding.
The other end 15B is in close contact with the inner circumferential surface of the handle main body 5, and the pipe end of the actuating pipe 12 is sealed by the valve plate 19A of the first valve body 19, so that air and Dirty water and the like will not flow back into the suction chamber 21. Therefore, the negative pressure in the suction chamber 21 is used only for pulling up the second valve body 20 and sucking out the chemical solution in the container 6.

In this manner, by opening the second valve body 19, the medicinal liquid 24 in the container 6 is sucked into the suction chamber 21 in the handle body 5 through the through hole 18 of the valve seat 16.

This suction causes the volume inside the container 6 to decrease, and following this decrease, the movable bottom body 23 moves forward in close contact with the inner circumferential surface of the container 6.

When the base 3A is pressed down again in the same manner as above, the second valve body 20 closes due to the entry of the actuating tube 12, and the medicinal liquid sucked into the handle body 5 flows into the conduit 12C of the actuating tube 12. , Notches 19D, 19D on the periphery of the valve plate 19A of the first valve body 19, 19D, 19D, 19D, 19D on the periphery of the valve plate 19B, around the same valve body 19, etc.
D, 19D, . . . , and is extruded through the chemical liquid passage 8 in the working tube 3 and the connecting pipe 3D, and an appropriate amount of the chemical liquid 24 oozes out at the root of the bristles 7.

When the pressure on the base 3A is released, the dispensing of the medicinal liquid 24 is stopped, the second valve body 20 is opened, and the medicinal liquid 24 is sucked into the suction chamber in the handle body 5 from inside the container 6 again. Due to this suction, the movable bottom body 23 in the container 6 moves forward according to the amount of the medicinal solution 24 poured out, as described above.

By performing this operation 2 to 3 times in the initial stage of use, the chemical liquid 24 is applied to the handle body 5 and the actuating tube 12.
The inside of each of the conduit 12C, the chemical liquid passage 8, and the connecting pipe 3D is filled with the chemical liquid 24, and from then on, each time the base 3A is pressed, one dose of the chemical liquid 24 oozes out onto the flocked surface of the brush part 3B and adheres to the hair. Can be done. In addition, if the amount of exudation is insufficient due to individual differences, please use 2 times.
It is only necessary to perform a pressing operation more than that.

In this way, chemicals can be applied to the hair and brushed, but in order to then hit the head, hold the handle part 2 and hit the scalp with the bristles 7, and the brush part 3B is connected to the base part 3A by a spring member. Due to the swinging motion due to the elasticity of 3C, the ball bounces appropriately and can be struck comfortably. In this case, since the connecting pipe 3D also has flexibility, the swinging motion of the brush portion 3B is not hindered.

When the entire chemical solution 24 in the container 6 has been used,
Unscrew the container 6 and valve seat 16, and insert a new container 6.
It can be used immediately by opening the package and screwing it back together. Furthermore, if there is a risk that the brush portion 3B may become dirty or the opening of the chemical liquid passage 8 may dry out during continued use, store the entire brush in a case or cover the entire bristles 7 with a cap. Just leave it there.
Further, the structures of the first and second valve bodies 19 and 20 are not limited to the illustrated embodiment, and valves having other structures may be used as long as they perform the same function.
