Specifically, as shown in fig. 5, the spring 300 includes a connection member 310, a first piston 320, and a pushing member 330. The connecting member 310 may have a hollow cylindrical structure, and an end of the connecting member 310 is open, and the inside of the connecting member is an air pressure cavity 301. The connecting member 310 is rotatably coupled to the toothbrush main body 100 through a rotation shaft. The first piston 320 is slidably mounted in the connecting member 310, and the space between the connecting member 310 and the first piston 320 is the air pressure chamber 301. The air holes 302 may be formed in the bottom plane of the connector 310. The pushing element 330 is fixedly connected with the first piston 320, and the pushing element 330 is controlled to drive the first piston 320 to move in the connecting element 310, so as to compress or expand the air pressure cavity 301. The pusher 330 protrudes out of the toothbrush body 100, and the user controls the movement of the pusher 330 by pressing the pusher 330 with a finger. Wherein, a chute 311 is provided on an outer wall of the connecting member 310, and the chute 311 extends along a moving direction of the first piston 320.

The inner wall of the pusher 330 is not tightly fitted to the outside of the connector 310, and there is a gap therebetween. Ambient air may enter the connector 310 to be replenished. A spring 340 is provided between the first piston 320 and the pneumatic chamber 301, one end of the spring 340 abuts against the first piston 320, and the other end abuts against the bottom of the connecting member 310. Normally, the spring 340 pushes the first piston 320 by its own elastic force, so that the first piston 320 moves in the direction of expanding the pneumatic chamber 301. The user presses the pusher 330, and the first piston 320 compresses the air pressure chamber 301 while compressing the spring 340. After releasing the pushing member 330, the first piston 320 is restored together with the pushing member 330 by the elastic pushing force of the spring 340. The pneumatic chamber 301 is reset from the compressed state to the expanded state, and the gas inside the pneumatic chamber can be restored to be filled in various manners. In this embodiment, as shown in fig. 4, the first piston 320 has a flared end 321 that can be elastically expanded and contracted, and the flared end 321 has a horn shape. When the first piston 320 compresses the air pressure cavity 301, the pressure in the air pressure cavity 301 increases, so that the flared end 321 is expanded outwards, the outer wall of the flared end 321 is in airtight fit with the inner wall of the connecting piece 310, and the air is discharged from the air hole 302 as much as possible when the air pressure cavity 301 is compressed. When the first piston 320 returns to the air pressure cavity 301 to expand, negative pressure is formed in the air pressure cavity 301, and the flared end 321 contracts inwards, so that a gap is formed between the outer wall of the first piston 320 and the inner wall of the connecting piece 310, and external air enters the air pressure cavity 301 through the gap to supplement the air in the air pressure cavity 301.

In some embodiments of the present utility model, as shown in fig. 6, a mounting location 140 is provided on the toothbrush body 100. The mounting position 140 may be formed by being recessed inward on the side wall of the toothbrush main body 100, or the mounting position 140 may be provided on the bottom of the toothbrush main body 100. Wherein the ends of the two ventilation channels 111 communicate to the mounting location 140. The pneumatic drive assembly is mounted within the mounting location 140. Be equipped with spacing muscle 141 in installation position 140, when pneumatic drive assembly rotated, utilize spacing muscle 141 to restrict pneumatic drive assembly's rotation stroke, can rotate pneumatic drive assembly anticlockwise or clockwise to spacing muscle 141 to its braking department, set for first position and second position to can guarantee the butt joint accuracy of gas pocket 302 and two runner 111 that ventilates.

In some embodiments of the present utility model, as shown in fig. 4 and 5, an air valve 350 is disposed at the air hole 302, and the air valve 350 is made of rubber, and has a certain elasticity. The air valve 350 may be snap-fit within the air hole 302 and seal the air hole 302. The gas valve 350 has a first end 351 and a second end 352, the first end 351 and the second end 352 communicating with each other. The first end 351 is connected to the pneumatic chamber 301 and the second end 352 is adapted to mate with the end of the vent flow passage 111. Two elastic flaps 353 which can be mutually opened and closed are arranged in the air valve 350. The resilient flap 353 slopes from the inner wall of the gas valve 350 toward the second end 352. When the pneumatic chamber 301 is compressed, gas flows through the first end 351 toward the second end 352, while the gas flushes the two elastic flaps 353, through the second end 352 and into the vent flow channel 111. When the air pressure cavity 301 is expanded, the air pressure cavity 301 forms negative pressure, and the two elastic flaps 353 are closed together, thereby closing the communication between the air pressure cavity 301 and the ventilation flow channel 111, and external air enters the air pressure cavity 301 from the outside of the toothbrush main body 100 along the air pressure driving assembly. This achieves that the gas valve 350 controls the unidirectional flow of the gas in the gas pressure chamber 301 to the ventilation flow passage 111.

Toothpaste is stored in the housing 220, one end of the housing 220 is a paste outlet 210, the other end is open to the storage chamber 110 and a second piston 230 enters from the end. When the air pressure chamber 301 is compressed, the air enters the storage chamber 110, and then pressurizes the storage chamber 110, and the pressure is transferred to the second piston 230, so as to push the second piston 230 to move in the housing 220. The second piston 230 slides toward the paste outlet 210, thereby extruding the paste in the housing 220 from the paste outlet 210.

In some embodiments of the present utility model, as shown in fig. 1 and 2, a perspective window 150 is formed on a sidewall of the toothbrush main body 100, and the perspective window 150 may be made of transparent plastic plate or transparent glass. The situation in the storage cavity 110 can be observed through the perspective window 150, so that the current use condition of each toothpaste piece 200 can be intuitively known, and the user can be prompted to replace.
