Description

Technical Field

[0001] The invention relates to the technical field of vacuum cleaners, in particular to a pet hair removal brush and a pet vacuum cleaner. Background Art

[0002] Currently there is a pet hair removal brush, which has the structural characteristics of including a handle, a comb plate and a suction port. The comb plate is used for combing hair, and part of the hair is combed off and sucked away through the suction port at the same time, while part of the hair is not easy to fall off the comb plate due to being soft or stuck, so it will be retained on the comb plate, causing cleaning trouble. For this reason, someone proposed to design a hair pushing plate, which is pushed along the surface of the comb plate to push the hair off the comb plate. Although this solves the problem, it is necessary to add an additional movable hair pushing plate, which makes the structure thicker. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and propose a pet hair removal brush that removes hair by retracting the comb plate without the need for an additional movable hair pushing plate, which is conducive to a thinner structure; a pet vacuum cleaner is also proposed, including the aforementioned pet hair removal brush.

[0004] Compared with the prior art, the present invention proposes a pet hair removal brush, including a handle, a comb plate and a suction port, a matching portion is provided on the suction port side, the comb plate and the matching portion can be slidably fitted together, the matching portion is provided with a matching hole extending along the length direction of the suction port and adjacent to the suction port, the comb plate can be extended through the matching hole, the extended part of the comb plate is used for combing hair, a scraping plate extending along the length direction of the matching hole is provided on the matching hole side, the scraping plate is used to scrape hair from the comb plate when the comb plate is retracted; the comb plate is connected to a pushing structure, the pushing structure includes a pushing portion and a control portion for user operation, the pushing portion is connected to the comb plate, and the pushing portion is actuated by the control portion to cause the comb plate to retract.

[0005] After adopting the above structure, compared with the prior art, the present invention has the following advantages:

[0006] In the present disclosure, a combing plate is used in the hair combing structure, and the combing plate and the matching part can be slidably fitted together, and the matching part is provided with a matching hole extending along the length direction of the suction port and adjacent to the suction port, the combing plate can be extended through the matching hole, and the extended part of the combing plate is used for combing hair, and a scraping plate extending along the length direction of the matching hole is provided on the side of the matching hole, and the scraping plate is used to scrape the combing plate when the combing plate is retracted, and the combing plate is movably arranged. When combing hair, the combing plate is in an extended state. When shaving is required, the user uses the operating part to move the pushing part to cause the combing plate to retract. When the combing plate is retracted, the scraping plate shaves the combing plate. In this way, there is no need to add an additional movable hair pushing plate. In addition, the structure is compact, which is conducive to a thin structure.

[0007] In some embodiments, the pushing structure includes a pressing part and a transmission structure, the pressing part serves as a control part, and the pressing part, the transmission structure, and the comb plate are sequentially connected along the telescopic direction to form a thin telescopic structure.

[0008] In some embodiments, the transmission structure adopts a gear rack transmission structure or a connecting rod transmission structure.

[0009] In some embodiments, the rack and pinion transmission structure includes a first rack, a second rack and a transmission gear. The first rack and the second rack are respectively meshed with both sides of the transmission gear and are both arranged along the extension direction. The first rack is connected to the pressing part, and the second rack is connected to the comb tooth plate. When the pressing part is pressed, the pressing part drives the first rack to move in the extension direction of the comb tooth plate, and drives the second rack to move in the retraction direction of the comb tooth plate in the reverse direction through the transmission gear. The movement of the second rack in the retraction direction of the comb tooth plate drives the comb tooth plate to retract.

[0010] In some embodiments, the connecting rod transmission structure includes an X-shaped folding connecting rod, wherein two adjacent ends of the X-shaped folding connecting rod are arranged on one side of the pressing portion and are defined as two upper ends, and the other two adjacent ends of the X-shaped folding connecting rod are arranged on one side of the comb tooth plate and are defined as two lower ends. The upper ends of the X-shaped folding connecting rod are movably connected to the pressing portion, and the lower ends of the X-shaped folding connecting rod are movably connected to the comb tooth plate. When the pressing portion is pressed, the pressing portion drives the upper ends to move in the extending direction of the comb tooth plate. Due to the linkage action of the X-shaped folding connecting rod, the lower ends will move in the retracting direction of the comb tooth plate at this time, and the movement of the lower ends in the retracting direction of the comb tooth plate drives the comb tooth plate to retract.

[0011] In some embodiments, a scraping plate is arranged between the comb plate and the suction port, and the scraping plate is inclined toward one side of the comb plate. The side of the scraping plate located on the suction port serves as an air guide surface, which guides the scraped hair to be sucked into the suction port.

[0012] In some embodiments, an elastic reset structure is further included. In the initial state, the elastic reset structure extends the comb plate. When the pushing structure is operated, the pushing structure overcomes the elastic force of the elastic reset structure to retract the comb plate.

[0013] In some embodiments, the elastic force of the elastic reset structure is set so that when combing the hair, when a large force is applied, the comb plate can be pushed back to avoid harm to the pet.

Before the pressing portion is pressed down, the second connecting port is connected to the connecting hole, and the second connecting port is connected to the external environment through the connecting hole. The airflow is sucked into the connecting flow channel from the second connecting port and the suction port. After the pressing portion is pressed down, the connecting hole is closed to close or reduce the connection between the connecting flow channel and the external environment, and the airflow is mainly sucked from the suction port.

DETAILED DESCRIPTION

[0039] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0040] Those skilled in the art should understand that, in the disclosure of the present invention, the orientation or position relationship indicated by the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0041] like Figures 1 to 12The figure shows a pet hair removal brush, including a handle 1, a comb plate 2 and a suction port 5. A matching portion 6 is provided on the side of the suction port 5. The comb plate 2 and the matching portion 6 can be slidably fitted together. The matching portion 6 is provided with a matching hole 7 extending along the length direction of the suction port 5 and adjacent to the suction port 5. The comb plate 2 can be extended through the matching hole 7. The extended part of the comb plate 2 is used for combing hair. A scraping plate 8 extending along the length direction of the matching hole 7 is provided on the side of the matching hole 7. The scraping plate 8 is used to scrape the comb plate 2 when the comb plate 2 is retracted; the comb plate 2 is connected to a pushing structure, the pushing structure includes a pushing portion and a control portion for user operation, the pushing portion is connected to the comb plate 2, and the comb plate 2 is retracted by causing the pushing portion to move through the control portion.

[0042] In order to make it thinner, the comb plate 2 is provided with a sheet-like comb tooth part, which can be extended through the matching hole 7, and the sheet-like comb tooth part is used for combing hair, and the scraping plate 8 is used for scraping the sheet-like comb tooth part when the sheet-like comb tooth part is retracted; the sheet-like comb tooth part, the scraping plate 8, and the suction port 5 are arranged in sequence in parallel along the thickness direction of the suction port 5, or the scraping plate 8, the sheet-like comb tooth part, and the suction port 5 are arranged in sequence in parallel along the thickness direction of the suction port 5.

[0043] In some embodiments, in order to facilitate production, such as Figure 7 , 8 As shown in , 9, the comb plate 2 includes a tooth plate 3 and a tooth plate base 4. The tooth plate 3 is in a sheet shape. The tooth plate 3 provides a sheet-shaped comb tooth part. The lower end of the sheet-shaped comb tooth part is provided with combing teeth. The tooth plate 3 and the tooth plate base 4 are connected to obtain the comb plate 2. The comb plate 2 is a thin part as a whole. The tooth plate 3 is generally a metal part, such as a tooth plate 3 made of stainless steel. In the present disclosure, the tooth plate base 4 is preferably a plastic part. In this way, it is convenient to injection-mold the structure required for the connecting and pushing structure on the tooth plate base 4, and the structure of the tooth plate 3 can be simplified, thereby facilitating production and assembly.

[0044] like Figure 6 , 7 As shown in FIGS. 8 and 9, the pushing structure includes a pressing part 9 and a transmission structure. The pressing part 9 is used as a control part. The pressing part 9, the transmission structure and the comb plate 2 are sequentially connected along the telescopic direction to form a thin telescopic structure. This is conducive to being thinner.

[0045] In some embodiments, the thickness direction of the pressing portion 9, the thickness direction of the transmission structure, and the thickness direction of the comb plate 2 are the directions of the smallest dimensions, so the thickness directions of the pressing portion 9, the thickness direction of the transmission structure, and the thickness direction of the comb plate 2 are kept consistent, so that the pressing portion 9, the transmission structure, and the comb plate 2 are sequentially connected along the telescopic direction to form a thin telescopic structure. This provides a structural solution for obtaining a thinner hair suction head 23, such as Figure 1 , 6 As shown, it can be seen intuitively that the hair suction head 23 is relatively thin.

[0046] Of course, the present disclosure is not limited to being made thinner, and the thickness can also be made thicker according to the appearance design requirements, that is, the first shell 30 of the hair suction head 23 is made thicker, and when the appearance needs to be thinner, that is, when it needs to be made thinner, then the first shell 30 must be made thinner, then the present disclosure can still be implemented, which is conducive to obtaining a hair suction head 23 with a thinner thickness.

[0047] Any suitable transmission structure can be applied to the present disclosure. From the perspective of structural simplicity and reliability, the transmission structure preferably adopts a gear rack transmission structure or a connecting rod transmission structure.

[0048] In some embodiments, Figure 7 , 8 As shown, the gear rack transmission structure includes a first rack 10, a second rack 11 and a transmission gear 12. The first rack 10 and the second rack 11 are respectively meshed with the two sides of the transmission gear 12 and are arranged along the extension direction. The first rack 10 is connected to the pressing part 9, and the second rack 11 is connected to the comb plate 2. When the pressing part 9 is pressed, the pressing part 9 drives the first rack 10 to move in the extension direction of the comb plate 2, and drives the second rack 11 to move in the retraction direction of the comb plate 2 in the reverse direction through the transmission gear 12. The second rack 11 moves in the retraction direction of the comb plate 2 to drive the comb plate 2 to retract. The above scheme is not only simple and reliable in structure, but also can be made thinner.

[0049] In some embodiments, Fig.12 As shown, the connecting rod transmission structure includes an X-shaped folding connecting rod 13, wherein two adjacent ends of the X-shaped folding connecting rod 13 are arranged on one side of the pressing portion 9 and are defined as two upper ends 14, and the other adjacent ends of the X-shaped folding connecting rod 13 are arranged on one side of the comb tooth plate 2 and are defined as two lower ends 15. The upper ends 14 of the X-shaped folding connecting rod 13 are movably connected to the pressing portion 9, and the lower ends 15 of the X-shaped folding connecting rod 13 are movably connected to the comb tooth plate 2. When the pressing portion 9 is pressed, the pressing portion 9 drives the upper ends 14 to move in the extension direction of the comb tooth plate 2. Due to the linkage effect of the X-shaped folding connecting rod 13, the lower ends 15 will move in the retraction direction of the comb tooth plate 2 at this time, and the movement of the lower ends 15 in the retraction direction of the comb tooth plate 2 drives the comb tooth plate 2 to retract. The above scheme is not only simple and reliable in structure, but also can be made thinner.

[0050] In order to adapt to the change of the lateral size of the X-shaped folding link 13 when folding, a matching groove 16 and a matching shaft 17 can be provided. The matching shaft 17 can slide in the matching groove 16 to adapt to the transmission and size change of the folding. The matching groove 16 can be provided at both ends of the X-shaped folding link 13, and correspondingly, the matching shaft 17 is provided on the comb plate 2. The matching groove 16 can also be provided on the comb plate 2, and correspondingly, the matching shaft 17 is provided at both ends of the X-shaped folding link 13. In this example, for example, Fig.12As shown, the lower two ends 15 are provided with matching grooves 16 , the matching shaft 17 is provided on the comb plate 2 , the upper two ends 14 are provided with matching shafts 17 , and the pressing portion 9 is provided with matching grooves 16 .

[0051] In some embodiments, Figure 2 , 3 As shown in 6, a scraping plate 8 is arranged between the combing plate 2 and the suction port 5, and the scraping plate 8 is arranged obliquely toward one side of the combing plate 2. The side of the scraping plate 8 located at one side of the suction port 5 serves as an air guide surface 18, and the air guide surface 18 guides the scraped hair to be sucked into the suction port 5. With this design, when shaving, the hair can be sucked into the suction port 5 very smoothly, which improves the suction performance and makes it difficult for the hair to run out or fall. In addition, the scraping plate 8 is arranged obliquely toward one side of the combing plate 2, which also makes the size of the suction port 5 larger in the thickness direction, which is more conducive to sucking in dirt when combing.

[0052] In some embodiments, Figure 7 , 8 , 9, and 11, it also includes an elastic reset structure. In the initial state, the elastic reset structure extends the comb plate 2. When the pushing structure is operated, the pushing structure overcomes the elastic force of the elastic reset structure to retract the comb plate 2. With this design, the extension of the comb plate 2 does not need to be operated by the user, and can be automatically reset.

[0053] Since the push structure is connected to the comb plate 2, the elastic reset structure can be arranged at a suitable position on the action path of the push structure and the comb plate 2 to provide an elastic restoring force, for example, Fig.11 The first spring 19 and the second spring 20 are included. The lower ends of the first spring 19 and the second spring 20 are connected to the tooth plate base 4. The upper ends of the first spring 19 and the second spring 20 are sleeved with the spring hole 43 arranged inside the first shell 30. Since the position of the spring hole 43 is fixed, when the comb plate 2 is retracted, that is, when it moves upward, the first spring 19 and the second spring 20 will be compressed. The first spring 19 and the second spring 20 provide elastic restoring force, which can reset the pushing structure and the comb plate 2. However, in order to ensure that the pressing part 9 is not loose, the pressing part 9 is also provided with a third spring 21. The pressing part 9 is provided with a There is a barb column 46, and the third spring 21 is sleeved on the barb column 46. A limiting column 45 is arranged inside the first shell 30. The barb column 46 is plugged and connected with the limiting column 45 to realize the connection between the pressing part 9 and the first shell 30 to complete the installation, and the third spring 21 is pre-tightened between the barb column 46 and the limiting column 45, and the pressing part 9 will not be loose. Under the axial limitation of the limiting column 45, the pressing part 9 cannot be separated from the first shell 30. There is an axial hole in the limiting column 45, and the barb column 46 is plugged in the axial hole. The barb column 46 can move axially in the axial hole, so that the pressing part 9 can move along the telescopic direction of the comb plate 2.

[0054] For example, in Fig.11 In the embodiment, the first spring 19 and the second spring 20 are also provided, and the X-shaped folding link 13 is rotatably sleeved on the rotating shaft 36. Since the compression and expansion of the X-shaped folding link 13 are stable and reliable, the elastic force provided by the first spring 19 and the second spring 20 can expand and reset the X-shaped folding link 13, and the pressing portion 9 can also be relatively reliably reset. In addition to the above scheme, the X-shaped folding link 13 can also be provided with a torsion spring at the rotating shaft 36, and the X-shaped folding link 13 is reset by the torsion spring. When the X-shaped folding link 13 is reset, the comb plate 2 and the pressing portion 9 are also reset.

[0055] In short, the elastic restoring structure can be arranged at a suitable position on the action path of the pushing structure and the comb plate 2 to provide an elastic restoring force.

[0056] In particular, in some embodiments, the elastic force of the elastic reset structure is set so that when combing hair, when a large force is applied, the comb plate 2 can be pushed back to avoid harm to the pet. After such a design, the present disclosure has a protective function and provides a comfortable combing hair pressure. When the combing hair pressure is exceeded, the comb plate 2 can be pushed back. Therefore, a pet hair removal brush for different pet needs can be developed. The selection of elastic force can be obtained through a limited number of experiments. For example, springs with different elastic coefficients are selected to manufacture a pet hair removal brush, and then the pressure when the comb plate 2 is pushed back is tested. The comb plate 2 can be pushed against a pressure detection plate to check the indentation depth. Pet hair removal brushes with different indentation depths are tested on the same pet to observe the pet's reaction and combing hair effect. Finally, a more preferred elastic force is obtained through multiple tests. Specifically, a spring with a preferred elastic coefficient is obtained for a part.

[0057] In particular, in some embodiments, Figure 1 , 8 As shown, it also includes a connecting hole 22 and a closing part. The comb plate 2 and the closing part are arranged in linkage. The connecting hole 22 connects the external environment with the hair suction flow channel. When the comb plate 2 is extended to comb the hair, the closing part is separated from the connecting hole 22, and the connecting hole 22 is in an open state. The airflow is sucked into the hair suction flow channel from the connecting hole 22 and the suction port 5. When the comb plate 2 is retracted to shave the hair, the closing part and the connecting hole 22 are restored to be connected or matched. The connecting hole 22 is closed to close or reduce the connection between the hair suction flow channel and the external environment, and the airflow is mainly sucked into the hair suction flow channel from the suction port 5. With this design, when the comb plate 2 is extended for combing hair, since the connecting hole 22 can also take in air, the suction force of the suction port 5 is appropriate, and the suction port 5 is not easy to be firmly attached to the surface of the pet, thereby reducing the discomfort of the pet and the trouble of user operation. When shaving hair, since it has been separated from the pet's surface, the connecting hole 22 is closed to close or reduce the connection between the hair suction flow channel and the external environment. The air flow is mainly sucked into the hair suction flow channel from the suction port 5. The suction port 5 has a large suction force, and the shaved hair can be sucked away without being easily dropped.

[0058] In some embodiments, Figure 1 , 2 As shown, the present invention includes a hair suction head 23 and a handle 1. The hair suction head 23 is designed to be thin, and the axis of the hair suction head 23 is arranged to intersect with the axis of the handle 1. Figure 2 The right-angle intersection shown in the figure may of course not be a right-angle intersection, and may be an obtuse angle intersection or an acute angle intersection. A pressing portion 9 serving as a control portion is provided at the upper end of the hair suction head 23, and a matching hole 7 and a suction port 5 are provided in parallel along the thickness direction at the lower end of the hair suction head 23. A matching portion 6 and a connecting flow channel 24 are provided in parallel along the thickness direction inside the hair suction head 23, and the transmission structure of the pushing structure and the connected comb plate 2 can be movably matched with the matching portion 6 along the telescopic direction of the comb plate 2, and the suction port 5 is connected to the main flow channel 25 in the handle 1 via the connecting flow channel 24, and the connecting flow channel 24 and the main flow channel 25 together constitute a hair suction flow channel.

[0059] In some embodiments, Figure 1 , 6 As shown in , 7 and 8, the pressing part 9 is provided with a connecting hole 22, and the connecting flow channel 24 includes a first connecting port 26 and a second connecting port 27. The first connecting port 26 is connected to the main flow channel 25, and the second connecting port 27 is connected to the pressing part 9. Before the pressing part 9 is not pressed down, the second connecting port 27 is connected to the connecting hole 22, and the second connecting port 27 is connected to the external environment through the connecting hole 22. The airflow is sucked into the connecting flow channel 24 from the second connecting port 27 and the suction port 5. After the pressing part 9 is pressed down, the connecting hole 22 is closed to close or reduce the connection between the connecting flow channel 24 and the external environment, and the airflow is mainly sucked from the suction port 5. With this design, the structure is simple and compact.

[0060] To further simplify the structure, Fig.11As shown, the pressing portion 9 is provided with a socket hole 29, and a connecting hole 22 is provided on the side wall of the socket hole 29. The socket hole 29 and the portion where the second connecting hole 27 is located can be socketed and matched along the telescopic direction of the comb plate 2. After the pressing portion 9 is pressed down, the portion where the second connecting hole 27 is located covers the connecting hole 22 to close it. In this example, the sleeve hole 29 is located at the rear side of the pressing portion 9, and the connecting hole 22 is set on the rear side wall of the pressing portion 9. After the pressing portion 9 is pressed down, the pressing portion 9 drives the sleeve hole 29 to move relative to the part where the second connecting port 27 is located along the telescopic direction of the comb plate 2. Then, the rear side surface of the part where the second connecting port 27 is located overlaps with the part of the rear side wall of the pressing portion 9 where the connecting hole 22 is located, thereby blocking the connecting port. Although the connecting port cannot be completely closed and there is still a situation where air enters from the matching gap, the purpose of closing is also achieved, and the air from the external environment entering the connecting flow channel 24 through the connecting hole 22 is greatly reduced. In addition, if the matching accuracy of the rear side surface of the part where the second connecting port 27 is located and the part of the rear side wall of the pressing portion 9 where the connecting hole 22 is located is set to be higher to reduce the gap, the purpose of complete closing can almost be achieved.

[0061] In particular, in some embodiments, Figure 5 , 6 As shown in Figures 7, 8, 9 and 10, the shell of the hair suction head 23 is recorded as the first shell 30, and the first shell 30 is set to pass through along the telescopic direction of the comb plate 2. The shell of the handle 1 is recorded as the second shell 31. The first shell 30 and the second shell 31 are set in one piece or in a split piece. The integrated setting is, for example, plastic injection molding. A flow channel component 32 is installed in the first shell 30, and the flow channel component 32 is provided with a connecting flow channel 24. The lower end of the flow channel component 32 is provided with a matching hole 7 and a suction port 5. An accommodating interval 33 is formed between the front side surface of the flow channel component 32 and the first shell 30. The transmission structure of the pushing structure and the connected comb plate 2 can be movably accommodated in the accommodating interval 33 along the telescopic direction of the comb plate 2, and the pressing portion 9 and the upper side opening of the first shell 30 can be movably sleeved and connected along the telescopic direction of the comb plate 2. With such a design, on the one hand, it is convenient for production and manufacturing, and on the other hand, at least the first shell 30 will not have any splicing seams, and there will be no problems of dirt and grime being trapped or pet hair being scratched by the splicing seams. It is also beneficial to the appearance design. Furthermore, when the first shell 30 and the second shell 31 are integrally arranged, the first shell 30 and the second shell 31 achieve a seamless integrity, which is of great structural help to the appearance design.

[0062] In some embodiments, a guide structure is provided between the inner side wall of the through hole 35 and the comb plate 2, and the guide structure includes a guide protrusion 37 and a guide groove 38 arranged along the telescopic direction of the comb plate 2. The guide protrusion 37 and the guide groove 38 can be arranged in a mutually complementary manner, that is, if the guide protrusion 37 is arranged on the inner side wall of the through hole 35, then the guide groove 38 is arranged on the comb plate 2. Conversely, if the guide protrusion 37 is arranged on the comb plate 2, then the guide groove 38 is arranged on the inner side wall of the through hole 35. In this way, the movement guiding property of the comb plate 2 is better, and in addition, the structure is simple and compact.

[0063] Further, one end of the guide groove 38 is closed, and the end is used to limit the extension stroke of the comb plate 2. In this way, the comb plate 2 is also limited while guiding.

A guide groove 38 is provided on the outer wall of the tooth plate base 4, and the upper end of the guide groove 38 is closed as a closed end 39. When the limiting end 44 abuts against the closed end 39, the comb plate 2 is limited.

[0065] In order to further ensure the reliability of the limit, a first limit inclined surface 47 and a second limit inclined surface 48 are provided. In this example, Figure 7 , 8 As shown, a first limiting inclined surface 47 is provided on the rear side of the tooth plate base 4, and a second limiting inclined surface 48 is provided on the front side of the flow channel assembly 32. The first limiting inclined surface 47 and the second limiting inclined surface 48 cooperate to limit along the telescopic direction of the comb plate 2. In addition, since the second limiting inclined surface 48 is inclined toward the rear side of the tooth plate base 4, the connecting flow channel 24 is expanded in the thickness direction, which is conducive to hair suction.

[0066] In particular, in some embodiments, the flow channel assembly 32 is first installed with the comb plate 2 and part or all of the push structure to obtain a first assembly, and then the first assembly is inserted into the opening of the first housing 30.

The comb plate 2 and the through hole 35 can be movably sleeved and connected along the telescopic direction of the comb plate 2. The front side of the flow channel assembly 32 is provided with a transmission gear 12, and the second rack 11 connected to the comb plate 2 is meshed with the transmission gear 12; the comb plate 2 and the transmission gear 12 are first installed on the flow channel assembly 32 to obtain the first assembly, and then the first assembly as a whole is sleeved and installed from the lower side opening of the first shell 30, and the pressing portion 9 is sleeved and installed from the upper side opening of the first shell 30, and the first rack 10 connected to the pressing portion 9 is meshed with the transmission gear 12. This design can greatly facilitate production and assembly.

[0068] like Figure 7 , 10 As shown, the main channel 25 is provided with a mating opening 28 at the intersection of the first shell 30 and the second shell 31 . When the first component is inserted into the lower opening of the first shell 30 , the first communication opening 26 can be mated with the mating opening 28 .

[0069] After the first component is inserted into the lower opening of the first housing 30, in order to ensure a firm connection and facilitate assembly, Figure 7 , 8 As shown in FIG. 11 , the flow channel component 32 is provided with a connecting column 42 , and the connecting column 42 is provided with a screw hole 40 . The entrances of the screw hole 40 are located on both sides of the suction port 5 , and the first component is fixed in the first shell 30 by screws.

[0070] In order to control the overall height of the hair suction head 23 and avoid interference when retracting, as Figure 7 , 8 As shown in Figures 9, the comb plate 2 is provided with a avoidance groove 41 arranged along the extension and retraction direction of the comb plate 2, that is, the tooth plate base 4 is provided with a avoidance groove 41, so as to avoid interference with the rotating shaft 36 or the transmission gear 12 when retracting when the overall height of the hair suction head 23 is short.
