[0029] The implementation modes of the present utility model are described in detail below in conjunction with the accompanying drawings.

[0030] like Figure 1 , Figure 2 and Figure 8 A pneumatic drive device is shown, comprising a main body 1, wherein the main body 1 comprises a connecting piece 3, a liquid outlet piece located on one side of the connecting piece 3, a driving assembly 5 located on the other side of the connecting piece 3, and a container 4 located on the inner side of the connecting piece 3 and connected to the liquid outlet piece, wherein the container 4 is elastic, the connecting piece 3 is also provided with a connecting piece inner cavity, an air pump assembly 52 is provided at one end of the driving assembly 5, and the air pump assembly 52 is communicated with the connecting piece inner cavity, and the air pump assembly 52 squeezes the container 4 by changing the air pressure in the connecting piece inner cavity, thereby extruding the substance.

[0031] In the present invention, the air pump assembly 52 and the container 4 are arranged in a sealed cavity 33, and the air pump assembly 52 is used to automatically generate air pressure to squeeze the container 4, so that the substance is uniformly squeezed out. Since the container 4 is elastic, when the air pump assembly 52 applies pressure, the container 4 will gradually shrink, prompting the substance to be uniformly transferred from the container 4 to the liquid outlet, thereby improving the stability of the liquid outlet effect. Optionally, in some embodiments, the pneumatic drive device can be used in the field of daily necessities, such as squeezing out fluids such as toothpaste, laundry detergent, hand soap, and detergent, and can also be used in the beauty field, such as squeezing out facial cream, hair dye, etc.

[0032] Specifically, the air pump assembly 52 has a constant pressure function, and continuously releases gas as the container 4 gradually contracts to ensure that the pressure in the sealed cavity 33 remains constant, ensuring that the container 4 can further contract, thereby smoothly extruding the substance; further, the constant pressure function also ensures that the container 4 can contract regularly, thereby ensuring that the substance can be extruded evenly.

[0033] Further, such as Figure 2 , Figure 6 and Figure 7A pneumatic drive device is shown, wherein a connecting portion 31 is provided on one side of the connecting member 3, and a first connecting port 34 is provided on the other side, the inner cavity of the connecting member includes a sealed cavity 33, and the sealed cavity 33 is communicated with the first connecting port 34, the liquid outlet member is provided with a first matching portion, and the container 4 is provided with a second matching portion, the first matching portion cooperates with the connecting portion 31 so that the liquid outlet member and the connecting member 3 can be detachably connected, and the second matching portion cooperates with the connecting portion 31 so that the container 4 and the connecting member 3 can be detachably connected.

[0034] In the present invention, both the liquid outlet and the container 4 can be detachably connected to the connecting member 3. This arrangement enables the user to easily disassemble and assemble the liquid outlet and the container 4 to facilitate cleaning and replacement of the hair dye.

[0035] Further, such as Figure 7 A pneumatic drive device is shown, wherein the container 4 is also provided with a second limiting surface 43 and a storage area 44 located on one side of the second limiting surface 43, the second matching portion includes a second connecting port 42 and a discharge hole 41 arranged on the inner side of the second connecting port 42, the second connecting port 42 is located on the other side of the second limiting surface 43, the storage area 44 is provided with a plane 441 for extrusion, the two planes 441 are arranged at an angle and intersect at the bottom of the storage area 44, and the storage area 44 has a triangular cross-section and is arranged in the sealing cavity 33.

[0036] In the utility model, planes 441 are provided on both sides of the storage area 44, which provide a fulcrum for the user to fix the container 4, so that the user can easily rotate the container 4 for installation, thereby ensuring that the installation of the container 4 is more convenient and stable; further, the cross-section of the storage area 44 is arranged in a triangular shape, which helps to extrude the hair dye more evenly. Since the bottom of the triangular shape is narrow, the hair dye is relatively concentrated at the bottom of the container 4. When the air pump assembly 52 applies pressure, the hair dye at the bottom of the container 4 pushes the hair dye at the upper end, making it easier to squeeze out the hair dye; further, the triangular shape also reduces the retention of the hair dye in the storage area 44, so that the hair dye can be squeezed more smoothly to the discharge hole 41, and then enter the comb body 2, thereby ensuring the continuity and fluency of the hair dyeing process.

[0037] Further, such as Figure 2 , Figure 6 and Figure 7 A pneumatic drive device is shown, wherein the second connecting port 42 is connected to the connecting portion 31 by matching, so that the container 4 is connected to the connecting piece 3, and a first limiting surface 331 is also provided on one side of the inner cavity of the connecting piece, and the first limiting surface 331 is abutted against the second limiting surface 43 to achieve sealing between the container 4 and the connecting piece 3.

[0038] In the utility model, the container 4 and the connecting member 3 can be matched by magnetic connection, fastener connection, threaded connection, snap connection, fastener connection, mortise and tenon connection, groove connection and the like, preferably threaded or snap connection, this arrangement ensures the firmness and stability of the connection between the container 4 and the connecting member 3, so that the container 4 and the connecting member 3 can better withstand the pressure in the sealing cavity 33 and the vibration during the operation of the hair dyeing comb without falling off; further, the first limiting surface 331 is offset against the second limiting surface 43 on the container, this arrangement realizes the sealing of the container 4 and the connecting member 3, and better ensures the sealing of the sealing cavity 33.

[0039] Further, such as Figure 8 A pneumatic drive device is shown, wherein the drive component 5 also includes an air pump component 52, a third connection port 51 located on one side of the air pump component 52, and a power supply component 53 located on the other side of the air pump component 52, the air pump component 52 is provided with an air outlet 521, and a start button 531 is provided on the side of the power supply component 53, the start button 531 extends out of the surface of the drive component 5, and the air outlet 521 of the air pump component 52 faces the bottom of the storage area 44.

[0040] In the utility model, the air outlet 521 of the air pump assembly 52 faces the bottom of the storage area 44, and because the cross-section of the storage area 44 is triangular and the bottom is relatively narrow, this arrangement makes it possible for the bottom of the storage area 44 to be squeezed more strongly when the air pressure generated by the air pump assembly 52 squeezes the container 4, thereby causing the hair dye in the container 4 to flow more easily to the liquid outlet.

[0041] Further, such as Figure 2 , Figure 5 and Fig. 9 A pneumatic drive device is shown, wherein the first connecting port 34 is symmetrically provided with a clamping block 341 on both sides, the third connecting port 51 is symmetrically provided with a first connecting area 511, a limiting area 512 located at one end of the first connecting area 511, and a second connecting area 513 located at the other end of the first connecting area 511 on both sides, the first connecting area 511 is respectively provided with a first limiting end 5111 and a second limiting end 5112 on the upper and lower sides, the clamping block 341 is clamped into the first connecting area 511 through the second connecting area 513, and the limiting area 512, the first limiting end 5111 and the second limiting end 5112 are used to fix the clamping block 341 so that the driving component 5 is connected to the connecting member 3.

[0042] In the utility model, the clamping block 341 is clamped into the first connecting area 511 through the second connecting area 513. This arrangement makes the connection between the connecting member 3 and the driving assembly 5 more convenient and quick; further, the limiting area 512 limits the position of the clamping block 341 after being locked, and the first limiting end 5111 and the second limiting end 5112 ensure the stability of the clamping block 341 in the vertical direction to prevent it from moving. This arrangement not only ensures that the relative position of the connecting member 3 and the driving assembly 5 is fixed after each locking, but also ensures a firm connection between them.

[0043] Further, such as Figure 2 and Figure 8 A pneumatic drive device is shown, wherein the third connection port 51 is provided with a sealing ring 542, and a first gasket 541 is provided between the third connection port 51 and the air pump assembly 52, and the first gasket 541 and the sealing ring 542 are made of silicone material to achieve sealing between the drive assembly 5 and the inner cavity of the connector.

[0044] In the utility model, the arrangement of the first gasket 541 and the sealing ring 542 enhances the sealing between the driving assembly 5 and the sealing chamber 33, and ensures the stability of the air pressure in the sealing chamber 33; further, the first gasket 541 and the sealing ring 542 are made of silicone material, which has good elasticity and durability, can effectively withstand pressure, and can maintain a good sealing effect for a long time.

[0045] Further, such as Figure 1-9 The electric hair dyeing comb shown includes a pneumatic driving device as described above, and the liquid outlet is a comb body 2 connected to one side of the connecting member 3.

[0046] In the utility model, the air pump assembly 52 and the container 4 are arranged in a sealed cavity 33, and the air pump assembly 52 is used to automatically generate air pressure to squeeze the container 4, so that the hair dyeing material is evenly squeezed out. Since the container 4 is elastic, when the air pump assembly 52 applies pressure, the container 4 will gradually shrink, so that the hair dyeing material is evenly transferred from the container 4 to the comb body 2, thereby improving the stability of the hair dyeing effect.

[0047] Specifically, the comb body 2 is connected to the outlet of the hair dyeing material in the container 4. When the air pump assembly 52 generates air pressure, the hair dyeing material in the container 4 is evenly squeezed, so that the hair dyeing material is evenly transferred from the container 4 to the comb teeth 212 of the comb body 2, thereby making the hair dyeing process more convenient and quick.

[0048] Further, such as Figure 1 , Figure 3 and Figure 6An electric hair dyeing comb is shown, wherein the comb body 2 is further provided with a liquid duct 213 located on the inner side, a liquid outlet 211 communicated with the liquid duct 213, comb teeth 212 located on the same side as the liquid outlet 211 and evenly arranged, and a fourth connecting port 215 communicated with the liquid duct 213, the fourth connecting port 215 is connected to the connecting part 31 by matching, so that the comb body 2 is connected to the connecting member 3, and a second gasket 214 is further provided between the fourth connecting port 215 and the connecting part 31, the second gasket 214 is made of silicone material, and the connecting part 31 is further provided with a pressing surface 312 located on the upper side, the pressing surface 312 presses the second gasket 214 to achieve sealing between the comb body 2 and the connecting member 3.

[0049] In the present invention, the liquid outlet 211 is arranged in the middle of the comb body 2, and the comb teeth 212 are arranged on both sides of the liquid outlet 211. This arrangement ensures that the hair dye can be evenly squeezed out of the comb body 2 and distributed on the comb teeth 212, thereby enhancing the consistency and stability of the hair dyeing effect; further, the liquid conduit 213 is connected to the liquid outlet 211, and the fourth connecting port 215 is connected to the liquid conduit 213. This arrangement provides a path for the hair dye to be transported from the container 4 to the comb body 2, ensuring that the hair dye can flow smoothly to the comb body 2. ; Further, the fourth connecting port 215 and the connecting part 31 can be matched with each other by means of magnetic connection, fastener connection, threaded connection, snap connection, fastener connection, mortise and tenon connection, groove connection, etc., preferably threaded or snap connection. This setting ensures a firm connection between the comb body 2 and the connecting part 3; further, the second gasket 214 between the fourth connecting port 215 and the connecting part 31 is made of silicone material, and the second gasket 214 is pressed by the pressing surface 312 of the connecting part 31, thereby enhancing the sealing effect of the comb body 2 and the connecting part 3 and effectively preventing the leakage of hair dye.

[0050] Further, such as Figure 2 , Figure 4 and Figure 6 In the electric hair dyeing comb shown, the fourth connection port 215 is provided with a third limiting surface 2151 , and the third limiting surface 2151 fixes the direction of the comb body 2 by cooperating with the connection part 31 .

[0051] In the present invention, the fourth connection port 215 is provided with a third limiting surface 2151 , and the third limiting surface 2151 cooperates with the connection portion 31 to ensure that the direction of the comb body 2 remains consistent after being locked.

[0052] like Figure 1-Figure 9 As shown, the implementation method of this embodiment is as follows:

[0053] When using the hair dyeing comb of the utility model, first, the user takes out the comb body 2 and the connecting member 3, puts the connecting part 31 into the fourth connecting port 215 and rotates the comb body 2, connects the comb body 2 with the connecting member 3 by means of threads or snaps, ensures that the connecting part 31 hits the third limiting surface 2151, and the comb body 2 cannot be rotated. Then, after the user takes out the container 4 and loads the hair dye material, the container 4 is placed in the sealed cavity 33, and connects the container 4 with the connecting member 3 by means of threads or snaps, ensures that the first limiting surface 331 is tightly attached to the second limiting surface 43, and the container 4 cannot be rotated. Next, the user takes out the driving assembly 5, extends the block 341 on the first connecting port 34 of the connecting member 3 into the second connecting area 513 of the driving assembly 5, rotates the driving assembly 5, and makes the block 341 snap into the first connecting area 511, until the block 341 hits the limiting area 512, and the assembly of the connecting member 3 and the driving assembly 5 is completed. After completion, the user can start or close the hair dyeing comb by the start button 531.

[0054] When the user needs to add hair dye to the container 4, first, the user needs to rotate the driving assembly 5 in the reverse direction to disengage the block 341 from the connection area, so that the driving assembly 5 is completely separated from the connecting member 3. Then, the user also twists the container 4 in the reverse direction and removes the container 4, adds the hair dye to the container 4, and then connects the container 4 to the connecting member 3.

[0055] When the user needs to clean the comb body 2 and the container 4, first, the user removes the container 4 according to the above steps of adding hair dye, then the user needs to rotate the comb body 2 in the opposite direction until the comb body 2 and the connecting member 3 are completely separated, remove the comb body 2, and clean the comb body 2 and the container 4. After cleaning, the components can be reassembled according to the above assembly method.

[0056] The above examples are only used to further illustrate the technical content of the utility model, so that readers can understand it more easily, but it does not mean that the implementation methods of the utility model are limited to this.
