The mixing channel 10a is partially arranged in the main shell 11 and partially arranged in the liquid storage cylinder 12. The liquid outlet 12b is arranged at the bottom of the liquid storage cylinder 12 away from the main shell 11. In the present application, the liquid outlet 12b is arranged at this position, which can further lengthen the mixing channel 10a, so that the time for the hair dyeing agent to flow in the mixing channel 10a is as long as possible, i.e. the mixing time is extended, so that the mixing effect of the hair dyeing agent is further improved. Of course, the liquid outlet 12b can also be arranged at the middle or top of the liquid storage cavity 12a, and its position can be arranged according to actual needs, which is not specifically limited here.

[0038] The liquid outlet head 20 can also be formed by metal or plastic material, which is formed with a liquid outlet channel and a plurality of liquid outlets 20a communicating with the liquid outlet channel. The end of the liquid outlet head 20 can be partially inserted into the mixing channel 10a to communicate the liquid outlet channel with the mixing channel 10a.

After the hair dye is applied to the hair, the comb teeth arranged outside the liquid outlet area 40a can further uniformly apply the hair dye, thereby improving the hair dyeing effect of the hair dyeing device 100.

[0040] In the present application, one or more hair dyes are stored in the liquid storage cavity 12a, under the action of an external force, the pressing member 31 moves in the liquid storage cavity 12a, under the action of atmospheric pressure, the hair dye is squeezed into the mixing channel 10a, after entering the mixing channel 10a, the hair dye is mixed or further refined by the mixing member 60 arranged in the mixing channel 10a, and the mixed hair dye is discharged to the outside through the liquid outlet 20a. In the present application, since the discharged hair dye passes through the mixing channel 10a and is mixed and stirred by the mixing member 60 arranged therein, the situation of uneven mixing of the hair dye can be avoided, and the effect of applying the hair dye by the hair dyeing device 100 is better.

[0041] Please refer again to Figure 2 and Figure 7 It should be noted that generally, when dyeing hair, two or more hair dyes are needed. When the liquid storage cavity 12a is one, in order to ensure better mixing effect of the hair dye, the two hair dyes can be pre-stirred by using a stirring tool after being added, so as to ensure that the two hair dyes can be fully contacted, and one liquid storage cavity 12a is simple in structure and convenient for production and manufacturing. In other embodiments, two or three or more liquid storage cavities 12a can be arranged, one liquid storage cavity 12a is connected in communication with the mixing channel 10a through one liquid passage 12b, so that the addition and cleaning of the hair dye are more convenient, and one hair dye is stored in one liquid storage cavity 12a, which can also facilitate the user to control the mixed dose. The number of the liquid storage cavities 12a is not specifically limited.

[0042] Further, in the present application, the opposite sides of the liquid storage cylinder 12 are provided with connecting buckles 121, and the main shell 11 is provided with connecting buckle holes 11b which are adapted to the connecting buckles 121, the connecting buckles 121 can be buckled in the connecting buckle holes 11b to connect the liquid storage cylinder 12 and the main shell 11. By setting the connecting buckles 121 and the connecting buckle holes 11b, the liquid storage cylinder 12 and the main shell 11 are connected, which not only has a simple structure, but also facilitates the user to disassemble and assemble the liquid storage cavity 12a, add hair dye to the liquid storage cavity 12a or clean the liquid storage cavity 12a. Of course, the liquid storage cylinder 12 and the main shell 11 can also be connected by threads, screws or magnets, which will not be described in detail here.

[0043] Please refer again to Figures 4 to 6 In an embodiment of the present application, the mixing member 60 comprises a threaded mixing rod 61 which is arranged in the mixing channel 10a and is detachably connected with the liquid storage cylinder 12. Specifically, the mixing member 60 further comprises an end cover 62, and the side of the liquid storage cavity 12a away from the main shell 11 is provided with a plug-in slot 11c which communicates with the mixing channel 10a, that is, the slot bottom wall of the plug-in slot 11c communicates with the mixing channel 10a, and the slot opening of the plug-in slot 11c faces downward of the liquid storage cylinder 12, and the diameter of the plug-in slot 11c is the same as that of the end cover 62. The end of the threaded mixing rod 61 is formed with a limiting protrusion (not shown in the figure), and when the threaded mixing rod 61 is inserted into the mixing channel 10a from the plug-in slot 11c, the limiting protrusion is fitted to the opening of the mixing channel 10a, the end cover 62 is clamped in the plug-in slot 11c and abuts against the limiting protrusion, thereby fixing the threaded mixing rod 61 in the mixing channel 10a. In the present application, by arranging the threaded mixing rod 61 in the mixing channel 10a, on the one hand, the flow distance of the hair dye in the mixing channel 10a can be further prolonged to improve the mixing effect of the hair dye; on the other hand, the spiral channel formed by the threaded mixing rod 61 can compress the hair dye to improve the flow and mixing speed of the hair dye, thereby improving the mixing effect of the hair dye. In addition, the threaded mixing rod 61 in the present application is fixed in the mixing channel 10a by the end cover 62, which has a simple structure and facilitates the customer to clean the threaded mixing rod 61. Of course, the threaded mixing rod 61 can also be directly connected to the end cover 62 by means of glue or hot melting, or connected to the end cover by means of screws or threads, which will not be specifically limited here.

[0044] Further, in the present application, the shell 10 is provided with a sealing ring 13 which is sleeved outside the end cover 62, and when the end cover 62 is clamped in the plug-in slot 11c, the end cover 62 elastically abuts against the slot side wall of the end cover 62 and the plug-in slot 11c. The setting of the sealing ring 13 can make the connection of the end cover 62 and the liquid storage cylinder 12 more firm, and also can avoid the hair dye in the mixing channel 10a from flowing out of the plug-in slot 11c.

[0045] In another embodiment of the present application, the mixing member 60 can also have other structures, for example, the mixing member 60 comprises a mounting rod, a plurality of blocking protrusions are formed on the surface of the mounting rod and are arranged along the extension direction and the circumferential direction of the mounting rod. By arranging the plurality of blocking protrusions, the hair dye can be further mixed and stirred.

[0046] The threaded mixing rod 61 is detachably connected with the liquid storage cylinder 12 to facilitate cleaning. Of course, the threads on the threaded mixing rod 61 can also be arranged on the side wall of the mixing channel 10a by integral molding; or a plurality of protrusions are formed on the side wall of the mixing channel 10a to improve the mixing effect of the hair dye. In this way, the number of components of the hair dyeing device 100 can be reduced, the assembly efficiency of the hair dyeing device 100 can be improved, and the production capacity can be improved.

[0047] Please refer again to Figures 2 to 4 In the present embodiment, the extrusion assembly further comprises a driving member and at least one transmission member 33, wherein the driving member is installed in the mounting cavity 11a of the main housing 11, the extrusion member is arranged in the liquid storage cavity 12a, and the transmission member 33 connects the driving member and the extrusion member 31.

[0048] Specifically, the transmission member 33 comprises a transmission sleeve 331 and a transmission screw 332, and the driving member comprises a driving motor 321 which can be a servo motor or a stepper motor. The driving motor 321 is fixed in the mounting cavity 11a, and the output shaft thereof is sleeved with an output gear 322. One end of the transmission screw 332 is sleeved with a driven gear 324, and the other end extends into the liquid storage cavity 12a. The driven gear 324 is engaged with the output gear 322. The transmission sleeve 331 is internally provided with threads matched with the transmission screw 332, and is sleeved on the outside of the transmission screw 332 and extends into the liquid storage cavity 12a. The middle part of the transmission sleeve 331 is slidably connected with the main housing 11, and the end part thereof is fixedly connected with the extrusion member 31. The extrusion member 31 reciprocally slides in the liquid storage cavity 12a.

[0049] In actual application, when the hair dye needs to be injected into the mixing channel 10a, the driving motor 321 rotates clockwise or counterclockwise, drives the transmission screw 332 to rotate clockwise or counterclockwise through the output gear 322 and the driven gear 324, and drives the transmission sleeve 331 connected therewith to ascend or descend. When the extrusion member 31 moves towards the bottom wall of the liquid storage cavity 12a, the hair dye is extruded into the mixing channel 10a by atmospheric pressure. When the extrusion member 31 moves away from the bottom wall of the liquid storage cavity 12a, part of the hair dye is extracted from the mixing channel 10a. In the present application, the structure of the driving member and the transmission member 33 is relatively simple, and the movement speed of the extrusion member 31 can be well controlled through the cooperation of the transmission sleeve 331 and the transmission screw 332, so that the extrusion amount of the hair dye can be well controlled.

[0050] In another embodiment of the present application, the transmission member 33 comprises a transmission gear 323 and a transmission rack, wherein the transmission gear 323 is sleeved on the output shaft of the driving motor 321, the transmission rack is slidingly connected in the mounting cavity 11a and connected with the extrusion member 31, and the transmission gear 323 is engaged with the transmission rack. The driving motor 321 rotates to drive the extrusion member 31 to reciprocate in the liquid storage cavity 12a.

[0051] It can be understood that the driving member and the transmission member 33 drive the extrusion member 31 to reciprocate in the liquid storage cavity 12a, and thus the structure thereof can be set according to actual needs. For example, the driving member comprises a driving cylinder, and the transmission connection is a transmission rod, one end of which is connected to the telescopic rod of the driving cylinder and the other end of which is connected to the extrusion member 31, that is, the extrusion member 31 is driven by the driving cylinder to reciprocate in the liquid storage cavity 12a.

[0052] For another example, in another embodiment, a driving cavity is formed in the mounting cavity 11a, the main shell 11 is provided with two air ports in communication with the driving cavity, and part of the extrusion member 31 is located in the driving cavity. The two air ports are respectively connected with an air pump, that is, the extrusion member 31 is driven to reciprocate in the liquid storage cavity 12a by the way of air inlet or air outlet in the driving cavity.

[0053] In the present application, the extrusion member 31 comprises an elastic gasket 312 of an extrusion seat 311, wherein the extrusion seat 311 is integrally formed of plastic material, the upper surface of which is provided with a clamping groove matched with the end of the transmission sleeve 331, and the elastic gasket 312 is made of silicone or rubber and is sleeved on the outer side of the extrusion seat 311. When the extrusion seat 311 is placed in the liquid storage cavity 12a, the elastic gasket 312 elastically abuts against the cavity side wall of the liquid storage cavity 12a. By arranging the elastic gasket 312 elastically abutting against the cavity side wall of the liquid storage cavity 12a, the situation that the hair dye flows out from the gap between the extrusion seat 311 and the extrusion member 31 when the extrusion member 31 extrudes the hair dye into the mixing channel 10a can be effectively avoided.

[0054] Further, in order to ensure the balance of the movement of the extrusion seat 311 in the liquid storage cavity 12a, in an embodiment of the present application, the extrusion assembly comprises two transmission members 33, the driving member comprises an output gear 322, two transmission gears 323 and two driven gears 324, the output gear 322 is sleeved on the output shaft of the driving motor 321, one driven gear 324 is sleeved on the end of one transmission screw 332, the two transmission gears 323 are engaged with one driven gear 324 and the output gear 322 respectively, and the two transmission members 33 are connected to the opposite sides of the extrusion seat 311 respectively. In the present application, by arranging the two transmission members 33, the stability of the movement of the extrusion seat 311 in the liquid storage cavity 12a can be ensured to a large extent, and the deflection of the extrusion seat 311 can be avoided. Meanwhile, by the cooperation between the output gear 322, the two transmission gears 323 and the two driven gears 324, one driving motor 321 can drive the movement of the two transmission members 33, so that the structure of the extrusion assembly is relatively simple, and the production and assembly are facilitated.

[0055] In the present application, the control assembly 50 is also arranged in the mounting cavity 11a, the control assembly 50 comprises a control board 51 and a control switch 52, the control board 51 is composed of a printed circuit board (PCB) and a plurality of electrical elements welded on the surface thereof, the control switch 52 is welded on the surface thereof, the driving motor 321 is connected to the control board 51 through a terminal connection line, and the control switch 52 can be used to control the opening, closing or use state of the hair dyeing device 100. By arranging the control board 51 and the control switch 52, the user can conveniently control the hair dyeing device 100.

[0056] In the present embodiment, the control assembly 50 further comprises a Hall switch (not shown in the figure), the Hall switch is arranged in the mounting cavity 11a and is in communication connection with the control board 51 through a terminal connection line, and the Hall switch is used to limit the movement stroke of the extrusion member 31. Specifically, when the extrusion member 31 moves to a preset position in the liquid storage cavity 12a, the Hall switch is triggered correspondingly, at this time, an electrical signal is transmitted to one side of the control board 51, and the control board 51 correspondingly controls the driving member to work, so as to ensure the stable and smooth work of the extrusion assembly.

[0057] The above description is only the preferred embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
