[0033] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0034] The present invention relates to a multifunctional toothbrush, comprising a toothbrush body 100, a toothpaste piece 200 and an air pressure drive assembly.

[0035] like Figure 1 and Figure 2 As shown, the toothbrush body 100 has a brush handle and a head 130. The brush handle and the head 130 can be set as a split splicing structure, and the head 130 can be replaced at any time, or the brush handle and the head 130 can be set as an integrated structure. Figure 3 As shown, a storage cavity 110 is provided within the toothbrush body 100. The two storage cavities 110 are independent of each other and can be arranged side by side within the handle of the toothbrush body 100 as shown. An extrusion channel 120 is provided within the toothbrush body 100. One end of the extrusion channel 120 is connected to the head 130 of the toothbrush body 100, and the other end is connected to the storage cavity 110. Two extrusion channels 120 can be provided, with each storage cavity 110 connected to the head 130 of the toothbrush body 100 via a separate extrusion channel 120. Alternatively, a single extrusion channel 120 can be provided, with the extrusion channel 120 split into two channels at a side near the storage cavity 110, with each channel connected to each storage cavity 110. A toothpaste piece 200 is installed in each storage cavity 110, and the toothpaste outlet 210 of the toothpaste piece 200 is connected to the extrusion channel 120. The user can choose different types of toothpaste or the same type of toothpaste for the two toothpaste pieces 200 according to their needs. The toothpaste piece 200 can be placed into the storage cavity 110 from the bottom of the toothbrush body 100, and then the bottom of the toothbrush body 100 is sealed by the cover.

[0036] like Figure 4 and Figure 5As shown, the pneumatic drive assembly includes a pneumatic chamber 301 and a spring-loaded member 300. The spring-loaded member 300 can change the size of the space of the pneumatic chamber 301. An air hole 302 is provided on the wall of the pneumatic chamber 301. When the spring-loaded member 300 reduces the space of the pneumatic chamber 301, the gas in the pneumatic chamber 301 is compressed and discharged outward from the air hole 302. The pneumatic drive assembly is movably mounted on the toothbrush body 100. The pneumatic drive assembly can be set to rotate relative to the toothbrush body 100, or the pneumatic drive assembly can be set to translate relative to the toothbrush body 100. The pneumatic drive assembly has a first position and a second position relative to the toothbrush body 100. When the pneumatic drive assembly moves to the first position, the air hole 302 docks with the ventilation flow channel 111 corresponding to one of the storage cavities 110; when the pneumatic drive assembly moves to the second position, the air hole 302 docks with the ventilation flow channel 111 corresponding to the other storage cavity 110. That is, the air pressure chamber 301 is connected to only one storage chamber 110 at a time through the air hole 302. The elastic member 300 compresses the gas in the air pressure chamber 301, and the compressed gas flows through the air hole 302 into the docking storage chamber 110. The air pressure in the storage chamber 110 rises, squeezing the toothpaste piece 200, causing the toothpaste in the toothpaste piece 200 to be squeezed out from the paste outlet 210 to the extrusion hole. The toothpaste flows along the extrusion channel 120 to the bottom of the toothbrush body 100, and is used to brush teeth with the bristles on the head 130. The air pressure drive assembly is used to select one of the storage chambers 110 for connection according to the user's needs. At the same time, the air pressure drive assembly is manually controlled to pressurize the storage chamber 110 to squeeze out the toothpaste. Two toothpastes can be integrated into the same toothbrush body 100 for selection, meeting the different brushing habits of users and being very convenient to carry and use.

[0037] The pneumatic drive assembly can be mounted on the toothbrush body 100 using a sliding connection, with the pneumatic drive assembly being controlled by translation to switch between the first and second positions. In this embodiment, the pneumatic drive assembly utilizes a rotational connection, with the pneumatic drive assembly being switched between the first and second positions by rotation. Graphic markings can be provided on the outer wall of the toothbrush body 100, and the pneumatic drive assembly rotates to the corresponding graphic marking to thereby switch to the first or second position.

[0038] Specifically, such as Figure 5As shown, the elastic member 300 includes a connecting member 310, a first piston 320 and a pushing member 330. The connecting member 310 can be a hollow cylindrical structure, with one end of the connecting member 310 open and the interior being an air pressure chamber 301. The connecting member 310 can be rotatably connected to the toothbrush body 100 via a rotating shaft. The first piston 320 is slidably installed in the connecting member 310, and the space between the connecting member 310 and the first piston 320 is the above-mentioned air pressure chamber 301. The air hole 302 can be provided on the bottom plane of the connecting member 310. The pushing member 330 is fixedly connected to the first piston 320, and the first piston 320 is driven to move in the connecting member 310 by controlling the pushing member 330, thereby compressing or expanding the air pressure chamber 301. The pushing member 330 extends out of the toothbrush body 100, and the user controls the movement of the pushing member 330 by pressing the pushing member 330 with his fingers. The outer wall of the connecting member 310 is provided with a chute 311 extending in the direction of movement of the first piston 320. The pushing member 330 may also be a hollow cylindrical structure, with one end of the pushing member 330 being sleeved onto the exterior of the connecting member 310. A slidable rib 331 is provided on the inner wall of the pushing member 330. The rib 331 is slidably connected within the chute 311. The rib 331 and the chute 311 cooperate to guide the movement of the pushing member 330, thereby guiding the movement of the first piston 320. The inner wall of the pushing member 330 is not tightly fitted to the exterior of the connecting member 310, and a gap exists between them. External air can enter the connecting member 310 for replenishment. A spring 340 is provided between the first piston 320 and the air pressure chamber 301, with one end of the spring 340 abutting against the first piston 320 and the other end abutting against the bottom of the connecting member 310. Under normal conditions, the spring 340 pushes the first piston 320 by its own elastic force, causing the first piston 320 to move in the direction of expanding the air pressure chamber 301. When the user presses the pusher 330, the first piston 320 compresses the air pressure chamber 301 and the spring 340 at the same time. After releasing the pusher 330, the elastic thrust of the spring 340 is used to reset the first piston 320 together with the pusher 330. The air pressure chamber 301 is reset from the compressed state to the expanded state, and there are many ways to restore the gas inside it. In this embodiment, as Figure 4 As shown, the first piston 320 has a flared end 321 that can elastically expand and contract. This flared end 321 is trumpet-shaped. When the first piston 320 compresses the air pressure chamber 301, the pressure in the air pressure chamber 301 increases, causing the flared end 321 to expand outward. The outer wall of the flared end 321 is in airtight contact with the inner wall of the connector 310, ensuring that when the air pressure chamber 301 is compressed, the gas is discharged from the air hole 302 as much as possible. When the first piston 320 returns to the air pressure chamber 301 and expands, a negative pressure is generated in the air pressure chamber 301, and the flared end 321 contracts inward, forming a gap between the outer wall of the first piston 320 and the inner wall of the connector 310. External gas enters the air pressure chamber 301 through the gap, replenishing the air pressure chamber 301.

[0039] In some specific embodiments of the present invention, Figure 6 As shown, a mounting position 140 is provided on the toothbrush body 100. The mounting position 140 can be formed by an inward depression on the side wall of the toothbrush body 100, or the mounting position 140 can be provided on the bottom of the toothbrush body 100. The ends of the two ventilation channels 111 are connected to the mounting position 140. The pneumatic drive assembly is installed in the mounting position 140. A limiting rib 141 is provided in the mounting position 140. When the pneumatic drive assembly rotates, the limiting rib 141 is used to limit the rotation stroke of the pneumatic drive assembly. The pneumatic drive assembly can be rotated counterclockwise or clockwise to the position where the limiting rib 141 brakes it, and is set to the first position and the second position, thereby ensuring the docking accuracy of the air hole 302 and the two ventilation channels 111.

[0040] In some specific embodiments of the present invention, Figure 4 and Figure 5 As shown, an air valve 350 is provided at the air hole 302. The air valve 350 is made of rubber and has a certain elasticity. The air valve 350 can be snap-fitted and fixed in the air hole 302 to seal the air hole 302. The air valve 350 has a first end 351 and a second end 352, and the first end 351 and the second end 352 are connected to each other. The first end 351 is connected to the air pressure chamber 301, and the second end 352 is used to tightly dock with the end of the ventilation channel 111. Two elastic flaps 353 that can open and close with each other are provided in the air valve 350. The elastic flaps 353 are inclined from the inner wall of the air valve 350 toward the second end 352. When the air pressure chamber 301 is compressed, the gas flows from the first end 351 to the second end 352, and at the same time, the gas pushes open the two elastic flaps 353 and enters the ventilation channel 111 through the second end 352. When the air pressure chamber 301 expands, negative pressure is generated in the air pressure chamber 301, and the two elastic flaps 353 move toward each other and close, thereby blocking the connection between the air pressure chamber 301 and the ventilation channel 111. External air enters the air pressure chamber 301 from the outside of the toothbrush body 100 along the air pressure drive assembly. In this way, the air valve 350 controls the one-way flow of air in the air pressure chamber 301 to the ventilation channel 111.

[0041] The toothpaste piece 200 may be made of a soft shell material, and the toothpaste piece 200 may be squeezed by the pressurization of the storage cavity 110. Figure 2As shown, the toothpaste holder 200 includes a hollow housing 220 and a second piston 230 slidably mounted within the housing 220. The toothpaste is stored within the housing 220. One end of the housing 220 forms a toothpaste outlet 210, while the other end is open and connected to the storage chamber 110, through which the second piston 230 enters. When the air pressure chamber 301 is compressed, gas enters the storage chamber 110, pressurizing the latter. This pressure is then transferred to the second piston 230, pushing it to move within the housing 220. The second piston 230 slides toward the toothpaste outlet 210, squeezing the toothpaste within the housing 220 out of the outlet 210.

[0042] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, a perspective window 150 is provided on the side wall of the toothbrush body 100. The perspective window 150 can be made of a transparent plastic plate or transparent glass. Through the perspective window 150, the situation inside the storage cavity 110 can be observed, thereby intuitively knowing the current usage status of each toothpaste piece 200 and prompting the user to replace it.
