Description

Technical Field

[0001] This invention belongs to the field of hair removal technology, and particularly relates to a hair removal device. Background Technology

[0002] In existing technologies, when cleaning pets such as cats and dogs, combs are often used to groom their fur. Because cats and dogs have dense, curly fur that easily sheds during grooming and gets tangled in the comb teeth, a large amount of pet hair tends to adhere to the comb teeth during brushing. Although some improved combs use hair-absorbing mechanisms to remove some loose hair during brushing, a significant amount still adheres to or even gets tangled in the teeth. This hair cannot separate from the teeth on its own, and the hair-absorbing mechanisms cannot completely separate it. Therefore, manual intervention is required to separate the hair from the teeth, which is very inconvenient. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hair removal device, comprising:

[0004] Hair suction unit, dust can unit, and main unit;

[0005] The hair removal assembly includes an air extraction housing with an air extraction channel. The air extraction channel includes an air inlet and an air outlet. The air inlet passes through one end of the air extraction housing, and the air outlet passes through the other end of the air extraction housing.

[0006] A limiting plate is set on the outer wall of the end of the air extraction housing where the air inlet is located. A through hole / slot is provided on the limiting plate, and the through hole / slot passes through the two opposite sides of the limiting plate.

[0007] A comb that slides into a through-hole / groove. The comb includes a combing part for combing hair and a support part for supporting the combing part. The combing part passes through a limiting plate and extends to the air inlet side.

[0008] The first driving component is connected to the comb to drive the comb to move relative to the limiting plate;

[0009] The dust can assembly includes a dust can and a bottom shell. The dust can and the bottom shell are sealed together and detachably connected. The dust can assembly is connected to the hair removal assembly via a flexible hose.

[0010] The main unit is located at the bottom of the dust can assembly, and the main unit and the dust can assembly are detachably connected. The main unit has a built-in suction motor, which is located below the bottom shell.

[0011] The hair-absorbing component is used to comb and absorb hair;

[0012] The dust can assembly is used to collect and filter the hair absorbed by the hair suction assembly;

[0013] The main unit is used to provide negative pressure for the dust can assembly.

[0014] The hair removal device provided in this embodiment of the invention has an air extraction housing that can be connected to an air extraction structure to form a hair removal device with an air extraction function. The air extraction channel allows hair that falls out during the combing process to pass through. The air outlet of the air extraction channel is used to connect to the air extraction structure, and the air inlet is used to suck in hair. The comb can be used to comb the hair. The comb and the air inlet work together to adsorb hair while combing, preventing hair from falling into the environment during the combing process. Moreover, the comb is movable. When hair is attached to the comb, the first driving component can cause relative movement between the comb and the limiting plate. The limiting plate restricts the movement of the hair, thereby allowing the hair to move relative to the comb and separating the hair from the comb. After the hair is separated from the comb, it will be transferred through the air extraction channel, thereby preventing the hair from falling into the environment and ensuring that the combing process is clean and convenient.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] like Figures 1-9 As shown, an embodiment of the present invention provides a hair removal device, comprising:

[0039] Hair suction assembly, dust can assembly 50 and main unit 6;

[0040] The hair removal assembly includes a suction housing 11, which has a suction channel 12. The suction channel 12 includes an air inlet 121 and an air outlet 122. The air inlet 121 passes through one end of the suction housing 11, and the air outlet 122 passes through the other end of the suction housing 11. After the suction housing 11 is connected to the suction structure 5, it can form a hair removal device for adsorbing hair. It can be used to adsorb hair in the environment to ensure a clean and hygienic environment. The suction structure 5 includes a dust can assembly 50 (described later) and a main unit 6.

[0041] A limiting plate 2 is provided on the outer wall of the end of the air extraction housing 11 where the air inlet 121 is located. A through hole / groove 21 is provided on the limiting plate 2, and the through hole / groove 21 penetrates the two opposite sides of the limiting plate 2.

[0042] Comb 3 is slidably engaged with through hole / groove 21. Comb 3 includes a combing part 31 for combing hair and a support part 32 for supporting the combing part 31. The combing part 31 passes through the limiting plate 2 and extends to the side of the air inlet 121. After the comb 3 is engaged with the limiting plate 2, when hair is attached to the comb 3, the comb 3 can be moved relative to the limiting plate 2. The limiting plate 2 blocks the hair attached to the comb 3, allowing the hair to move relative to the comb 3, thereby facilitating the separation of the hair attached to the comb 3 from the comb 3.

[0043] The first driving component 4 is connected to the comb 3 to drive the comb 3 to move relative to the limiting plate 2. There are many ways to implement the first driving component 4, such as any one of electric driving component, pneumatic driving component, magnetic driving component or corresponding lever structure, as long as it can drive the comb 3 to move relative to the limiting plate 2. These are listed one by one here.

[0044] The dust can assembly 50 includes a dust can 51 and a bottom shell 52. The dust can 51 and the bottom shell 52 are sealed together and detachably connected. The dust can assembly 50 is connected to the hair removal assembly via a hose.

[0045] The main unit 6 is located at the bottom of the dust can assembly 50, and the main unit 6 is detachably connected to the dust can assembly 50. The main unit 6 has a built-in suction motor, which is located below the bottom shell 52.

[0046] The hair-absorbing component is used to comb and absorb hair;

[0047] The dust can assembly 50 is used to collect and filter the hair absorbed by the hair suction assembly;

[0048] The main unit 6 is used to provide negative pressure for the dust can assembly 50.

[0049] The hair removal device provided in this embodiment has an air inlet 121 on the air extraction channel 12 of the air extraction housing 11 for sucking up hair, and an air outlet 122 for connecting to the air extraction structure 5. The limiting plate 2 can restrict the movement of hair attached to the comb 3 relative to the comb 3. Therefore, during the combing process, if hair is attached to the comb 3, it can be moved relative to the limiting plate 2, causing the comb 3 and hair to move relative to each other, thereby separating the hair from the comb 3 and sucking it into the air extraction structure 5 through the corresponding air inlet 121. The comb 3 is positioned at the air inlet 121. On one side, when the comb 3 combs the hair, some loose hair is sucked into the inlet and transferred and collected, preventing hair from scattering into the environment during hair removal, thus ensuring a clean and tidy environment; the first drive component 4 facilitates the control of the movement of the comb 3, making operation convenient; the dust can assembly 50 can collect and filter the hair absorbed by the hair suction component, while the main unit 6 can provide negative pressure for the hair suction component and the dust can assembly 50, so that the hair suction component can smoothly absorb and transfer the fallen hair into the dust can assembly 50, thus facilitating cleaning.

[0050] Optionally, the air inlet 121 is positioned near the through hole / groove 21, which facilitates the entry of hair into the air inlet 121.

[0051] Optionally, the width of the air inlet 121 is roughly the same as the width of the through hole / groove 21 and the width of the comb 3. Here, "roughly the same" means that they do not need to be exactly the same and can be slightly different. In this way, the difference between the width of the air inlet 121 and the width of the comb 3 is small, which is beneficial for the air inlet 121 to pick up the hair that falls off from the comb 3 during the combing process.

[0052] Optionally, a conical protrusion 13 is provided between the air inlet 121 and the through hole / groove 21. The conical protrusion 13 has a straight surface 131 and a tapered surface 132. The straight surface 131 is located on the extension surface of the groove wall of the through hole / groove 21. The head of the conical protrusion 13 is connected to the side wall of the air inlet 121 through the tapered surface 132. The air intake surface of the air inlet 121 extends to the position of the comb 3 along with the tapered surface 132 of the conical protrusion 13. This is more conducive to the hair on the comb 3 being sucked into the suction structure 5 through the air inlet 121 during the combing process.

[0053] Optionally, a guide structure is provided between the comb 3 and the air extraction housing 11; the comb 3 slides along the guide structure, and the corresponding guide structure facilitates movement in the guiding direction, thereby ensuring the stability of the sliding.

[0054] Optionally, the guiding structure is a guide groove or / and a strip. In this embodiment, the suction housing 11 is provided with a first guide groove 14, which slides in cooperation with the outer side wall of the comb 3. The suction housing 11 is also provided with a guide strip 15, and the comb 3 is provided with a second guide groove 3a that cooperates with the guide strip 15. The first guide groove 14 and the guide strip 15 are both provided along the extension direction of the suction housing 11. The provision of the first guide groove 14, the guide strip 15 and the second guide groove 3a can restrict the comb 3 from sliding along the extension direction of the side wall of the suction housing 11, ensuring the stability of the sliding.

[0055] Optionally, the vacuum housing 11 includes a first section 11a and a second section 11b that are interconnected, with the first section 11a and the second section 11b arranged at an angle to facilitate gripping and use by the user.

[0056] Optionally, the included angle is an obtuse angle, which is convenient for the user to grip and use.

[0057] Optionally, the first driving member 4 includes a transmission rod 42, one end of which is movably connected to the comb 3, and the other end of which is movably connected to the air extraction housing 11 to form a lever structure for driving the comb 3 to move.

[0058] Optionally, an elastic element is provided between the transmission rod 42 and the suction housing 11. The elastic element facilitates the automatic reset of the transmission rod 42 after it is pressed down. At the same time, the elastic element can also push the transmission rod 42 to keep the comb 3, which is movably connected to the transmission rod 42, in a state that protrudes from the limiting plate 2, thereby facilitating the grooming of pet hair.

[0059] Optionally, an elastic element is provided between the comb 3 and the suction housing 11. The connection structure between the elastic element and the suction housing 11 is not shown in the accompanying drawings of this embodiment, but those skilled in the art can easily conceive of it by providing a corresponding elastic element receiving groove / hole or other feasible limiting structure on the side wall of the suction housing 11, which will not be detailed here. The use of the elastic element facilitates the maintenance and reset of the comb 3. For example, when the elastic element abuts against the end of the comb 3 away from the combing part 31, the elastic element facilitates keeping the combing part 31 of the comb 3 protruding from the limiting plate 2. At this time, the comb 3 can be used for combing. When the comb 3 is driven to move relative to the limiting plate 2 by the first driving member 4, and the hair attached to the comb 3 is separated from the comb 3, the spring 41 can push the comb 3 back to the state protruding from the limiting plate 2. Another example is when the elastic element abuts against the end of the comb 3 near the combing part 31...

[0060] Optionally, the elastic element is a spring 41 or a spring sheet; the spring 41 and the spring sheet have the characteristics of low cost, easy installation and disassembly, and convenient use, which can simplify the product structure and reduce the manufacturing cost.

[0061] Optionally, the first driving component 4 includes a flexible transmission rod 42, one end of which is movably connected to the comb 3, and the other end of which is fixedly connected to the suction housing 11. This way, only the transmission rod 42 is needed to move the comb 3. Initially, the transmission rod 42 is in its natural state, and the comb 3 protrudes from the limiting member 2, allowing it to be used for grooming pet hair. When hair removal is needed, the transmission rod 42 can be pressed down, causing it to deform and thus move the comb 3. This reduces the distance the comb 3 protrudes from the limiting member 2. During the movement of the comb 3, the limiting member 2 restricts the hair from moving with the comb, thus separating the hair from the comb 3. After the hair on the comb 3 detaches from the comb 3, releasing the transmission rod 42 causes it to reset under its own elasticity, thereby resetting the comb 3.

[0062] Optionally, the hair-absorbing assembly provided in this embodiment of the invention further includes a limiting slot 16, which is connected to the air outlet 122. The limiting slot 16 facilitates quick connection and disassembly of the hair-absorbing assembly and the air extraction structure 5, making it easy to operate.

[0063] Optionally, the hair-absorbing assembly provided in this embodiment of the invention further includes a limiting slot 16, which is integrally formed with the air outlet 122. The limiting slot 16 facilitates quick connection and disassembly between the hair-absorbing assembly and the air extraction structure 5, making it easy to operate.

[0064] Optionally, the hair suction assembly provided in this embodiment of the invention further includes a limiting slot 16, which shares the same opening as the air outlet 122. The limiting slot 16 facilitates quick connection and disassembly between the hair suction assembly and the air extraction structure 5, making it easy to operate.

[0065] See Figures 6-8 Optionally, the hair-absorbing component provided in this embodiment of the invention further includes a first housing 1, an air-suction housing 11, a comb 3, and a first driving component 4, which are at least partially embedded inside the first housing 1. After the first housing 1, the comb 3, and the first driving component 4 are at least partially embedded inside the first housing 1, on the one hand, the corresponding transmission structure can be prevented from being interfered with and affected by the external environment during use, and on the other hand, it is beneficial to make the product appearance simpler and more beautiful.

[0066] Optionally, the hair-absorbing assembly provided in this embodiment of the invention includes a first housing 1 comprising at least a first sub-housing 1a and a second sub-housing 1b, which are snap-fitted, glued, or threaded together. A button hole 17 is provided on the first sub-housing 1a, and the first driving member 4 includes a protruding button 42a, which is movably disposed within the button hole. Setting the first housing 1 as a combination of at least the first sub-housing 1a and the second sub-housing 1b facilitates production and assembly, and the button hole 17 on the first sub-housing 1a facilitates operation.

[0067] The hair removal device provided in this embodiment of the invention has an air extraction housing 11 that can be connected to an air extraction structure 5; an air extraction channel 12 allows hair that falls out during the combing process to pass through, an air outlet 122 of the air extraction channel 12 is used to connect to the air extraction structure 5, and an air inlet 121 is used to suck in hair; a comb 3 can be used to comb the hair, and the comb 3, in conjunction with the air inlet 121, can adsorb hair while combing, preventing hair from falling into the environment during the combing process; moreover, the comb 3 is movable, and when hair is attached to the comb 3, the first driving member 4 can cause relative movement between the comb 3 and the limiting plate 2, and the limiting plate 2 restricts the movement of the hair, thereby allowing the hair to move relative to the comb 3, realizing the separation of the hair from the comb 3. After the hair is separated from the comb 3, it will be transferred through the air extraction channel 12, thereby preventing the hair from falling into the environment and ensuring that the combing process is clean and convenient.

[0068] See Figures 10-15 The hair removal device provided in this embodiment of the invention also includes a dust can assembly 50, which is disposed on the main unit 6 and is used to collect and filter waste, including dust, hair, and other debris or waste. The dust can assembly 50 includes:

[0069] Dust canister 51, the interior of dust canister 51 is hollow, the top and sides of dust canister 51 are closed, and the bottom is open 511;

[0070] The bottom shell 52 is at least partially separable from the bottom opening 511 of the dust can 51, and the bottom shell 52 is sealed to the dust can 51.

[0071] A protruding ring 521 is provided on the bottom shell 52. The axis of the protruding ring 521 is set in the vertical direction. The protruding ring 521 protrudes from the upper surface of the bottom shell 52. The inner ring hole 5211 of the protruding ring 521 penetrates the bottom of the bottom shell 52.

[0072] A filter cover 522 is provided on the top of the convex ring 521, and an opening 511 is provided at the bottom of the filter cover 522. The bottom opening 511 of the filter cover 522 is connected to the inner ring hole 5211 of the convex ring 521.

[0073] An air inlet channel 523 is installed on the bottom shell 52. One end of the air inlet channel 523 is connected to the inside of the dust tank 51, and the other end of the air inlet channel 523 is connected to the bottom of the bottom shell 52.

[0074] The hair removal device provided in this embodiment of the invention has a dust can assembly 50 for collecting dust and hair. Since the dust can 51 is sealed to the bottom shell 52, the dust can assembly 50 will not scatter into the environment after being separated from the main unit 6. The dust can assembly 50 can be detached from the main unit 6 as a whole and transferred to a preset position for opening. This ensures cleanliness and reduces the weight of the transfer part, facilitating transfer. The filter cover 522 is located on top of the convex ring 521. The filter cover 522 is positioned relatively high, so when dust enters the dust can 51, most of the dust will not reach the position of the filter cover 522 above the convex ring 521 due to insufficient lift, thus... This design avoids clogging of the filter holes in the filter cover 522, ensuring its normal operation even without enlarging the filter holes. Furthermore, the protruding ring 521 restricts the entry of some debris into the filter cover 522, reducing the amount of debris passing through it and consequently reducing the amount of debris entering the first filter element 54, thus extending its lifespan. The protruding ring 521 also allows some debris to fall onto the bottom shell 52 under its own weight without passing through the filter cover 522, allowing more debris to be stored inside the dust can 51. This improves the utilization rate of the internal space of the dust can 51, reduces the frequency of cleaning, and ensures normal operation.

[0075] Optionally, the inner wall of the dust can 51 is a smooth surface, which is not conducive to the adhesion of garbage and makes cleaning easier.

[0076] Optionally, the inner wall of the dust can 51 has a circular cross-section. The circular dust can 51 has an aesthetically pleasing design, and garbage does not easily adhere to it, making it easy to clean.

[0077] Optionally, the inner wall side and top surface of the dust can 51 are connected by an arc transition. This helps to ensure the smoothness of the connection between the inner wall side and bottom surface of the dust can 51. The arc transition area is less prone to garbage adhesion and is easy to clean.

[0078] Optionally, the upper part of the dust can 51 is in the shape of an inverted bowl, basin, or hemisphere, which makes it easier for waste to adhere to the top of the dust can 51 and thus facilitates cleaning.

[0079] Optionally, the dust can 51 is cylindrical, and the top periphery of the dust can 51 is provided with a circumferentially rounded corner. Compared with a right angle, dust and hair and other debris are less likely to adhere at the rounded corner, making it easier to clean.

[0080] Optionally, the bottom shell 52 and the dust canister 51 are detachably connected; this facilitates complete separation between the bottom shell 52 and the dust canister 51, making it convenient to empty the garbage in the dust canister 51 and clean the inside of the dust canister 51.

[0081] Optionally, one end of the bottom shell 52 is hinged to the dust can 51, and the other end of the bottom shell 52 is detachably connected to the dust can 51. This allows the bottom shell 52 to be partially separated from the dust can 51 by opening the detachable end, making it convenient to empty the garbage in the dust can 51 and clean the inside of the dust can 51. At the same time, the hinged position ensures that the bottom shell 52 and the dust can 51 remain connected, preventing the bottom shell 52 or the dust can 51 from being lost after separation.

[0082] Optionally, one end of the bottom shell 52 is rotatably connected to the dust can 51, and the other end of the bottom shell 52 is snapped into the dust can 51. This allows the bottom shell 52 to be partially separated from the dust can 51 by opening the snapped end, making it convenient to empty the garbage in the dust can 51 and clean the inside of the dust can 51. At the same time, rotating the connection position ensures that the bottom shell 52 and the dust can 51 remain connected, preventing the bottom shell 52 or the dust can 51 from being lost after separation. The snap-fit ​​connection method is also convenient for operation.

[0083] Optionally, one end of the bottom shell 52 is rotatably connected to the bottom of the dust can 51. A first buckle is provided on one of the bottom shell 52 and the dust can 51, and a second buckle is provided on the other. The first buckle and the second buckle engage with each other, which facilitates quick engagement and disengagement of the bottom shell 52 and the dust can 51.

[0084] See Figure 10 , 12 14, 15, Optionally, at least one of the first buckle and the second buckle is a movable buckle 53, the movable buckle 53 includes a card plate 531, one end of the card plate 531 is provided with a card slot 5311;

[0085] The middle part of the clamping plate 531 is rotatably connected to the bottom of the side wall of the dust can 51, and the other end of the clamping plate 531 elastically abuts against the side wall of the dust can 51; a sliding block 532 is also provided between the clamping plate 531 and the side wall of the dust can 51, the sliding block 532 slides with the side wall of the dust can 51, the sliding block 532 slides in the up and down direction, and a limiting part 526 is provided above the sliding block 532, and the sliding block 532 elastically abuts against the limiting part 526; in this embodiment, pressing the upper end of the clamping plate 531 will cause the lower end of the clamping plate 531 to deflect, and the buckle on the bottom shell 52 (the other buckle 520 of the first buckle and the second buckle) enters the clamping plate 531. When the 1 is in the locking position 5311, the buckle on the bottom shell 52 will press against the sliding block 532, overcoming the pushing force of the sliding block 532, allowing the sliding block 532 to move upward. After the locking plate 531 is released, the locking plate 531 returns to its original position, and the first buckle and the second buckle smoothly engage, thus allowing the dust can 51 to engage with the bottom shell 52. When separating, pressing the top of the locking plate 531 will reset the sliding block 532, move it downward, and push the buckle on the bottom shell 52 (the other buckle 520 of the first and second buckles) out of the locking position 5311 of the locking plate 531. The first buckle and the second buckle separate, thus allowing the bottom shell 52 to partially separate from the dust can 51.

[0086] Optionally, at least one of the first buckle and the second buckle is a movable buckle 53, which includes a locking plate 531, and one end of the locking plate 531 is provided with a locking position 5311;

[0087] The middle part of the clamping plate 531 is rotatably connected to the side wall of the bottom shell 52, and the other end of the clamping plate 531 elastically abuts against the side wall of the bottom shell 52; a sliding block 532 is also provided between the clamping plate 531 and the side wall of the bottom shell 52, the sliding block 532 slides with the side wall of the bottom shell 52, the sliding block 532 slides in the up and down direction, and a limiting part 526 is provided below the sliding block 532, and the sliding block 532 elastically abuts against the limiting part 526; in this embodiment, pressing the lower end of the clamping plate 531 will cause the upper end of the clamping plate 531 to deflect, and the buckle on the dust can 51 (the other buckle 520 of the first buckle and the second buckle) enters the clamping plate 531. When the device is in position 5311, the latch on the dust can 51 will press against the sliding block 532, overcoming the pushing force of the sliding block 532, allowing the sliding block 532 to move downward. After the latch plate 531 is released, the latch plate 531 returns to its original position, and the first latch and the second latch smoothly engage, thus allowing the dust can 51 to engage with the bottom shell 52. When separating, pressing down on the lower part of the latch plate 531 will cause the sliding block 532 to return to its original position and move upward, pushing the latch of the dust can 51 (the other latch 520 of the first and second latches) out of the latch plate 531 in position 5311. The first latch and the second latch separate, thus allowing the bottom shell 52 to partially separate from the dust can 51.

[0088] Optionally, the card plate 531 is elastically abutted against the dust can 51 or the bottom shell 52 by a first spring 533.

[0089] Optionally, the sliding block 532 is elastically abutted against the dust can 51 or the bottom shell 52 by a second spring 534.

[0090] Optionally, the card plate 531 includes a first limiting plate 5312 and a second limiting plate 5313 disposed opposite to each other, and a sliding block 532 is slidably disposed between the first limiting plate 5312 and the second limiting plate 5313. A limiting post 535 is provided on the outer peripheral wall of the dust tank 51 or the side wall of the bottom shell 52, and a first limiting groove 5321 is provided on the sliding block 532 to slide and cooperate with the limiting post 535.

[0091] See Figures 10-15 Optionally, the convex ring 521 and the bottom shell 52 are integrally formed, which is simple and easy to clean.

[0092] Optionally, the convex ring 521 is detachably connected to the bottom shell 52.

[0093] Optionally, the protruding ring 521 is engaged with the bottom shell 52.

[0094] Optionally, the convex ring 521 is conical; the outer wall of the conical convex ring 521 is not conducive to the adhesion of garbage, making it easy to clean, and also makes it easy for garbage to slide down to the height angle position of the upper surface of the bottom shell 52, thereby facilitating garbage collection.

[0095] Optionally, the top of the filter cover 522 is provided with filter holes.

[0096] Optionally, the filter cover 522 has filter holes on its sidewall.

[0097] Optionally, filter holes are provided on the top and side walls of the filter cover 522.

[0098] Optionally, the filter holes are arranged in an array.

[0099] Optionally, all filter pores have the same diameter.

[0100] Optionally, the pore size of each filter hole is set to gradually change.

[0101] Optionally, the filter holes are located on the side wall of the filter cover 522, with the upper filter hole diameter being larger than the lower filter hole diameter. Generally, the higher the height of the garbage, the more difficult it is to rise. The lower filter hole diameter is smaller and has weaker adsorption capacity, which is not conducive to garbage adhesion. Although the upper filter hole diameter is larger and has stronger adsorption capacity, the garbage is difficult to rise to that height due to the greater height, making it difficult for the garbage to reach the upper filter hole. Under the same negative pressure, this is more conducive to the garbage in the dust can 51 falling to the upper surface of the bottom shell 52, thus facilitating garbage collection. At the same time, it helps to reduce the amount of garbage entering the first filter element 54 and extend the service life of the first filter element 54.

[0102] Optionally, the pore size of the filter holes near the air inlet channel 523 is smaller than that of the filter holes far from the air inlet channel 523. Generally, the farther the waste travels, the greater the difficulty. The filter holes near the air inlet channel 523 have a stronger adsorption effect on the waste entering the dust can 51 from the air inlet channel 523 than those far from the air inlet channel 523. Reducing the pore size of the filter holes near the filter channel helps to reduce the adsorption capacity of the filter holes near the filter channel, making it easier for the waste to fall onto the upper surface of the bottom shell 52. On the other hand, increasing the pore size of the filter holes far from the filter channel is beneficial. To maintain negative pressure inside the dust can 51 and ensure the filtration capacity of the dust can assembly 50, even if the filter holes far from the filter channel have strong adsorption capacity, the distance that the garbage needs to travel is longer and more difficult to reach the location due to their distance from the filter channel. This also weakens the adsorption capacity of the filter holes far from the filter channel. This helps to maintain negative pressure inside the dust can 51, making it easier for the garbage to fall onto the upper surface of the bottom shell 52 for collection. At the same time, it helps to reduce the amount of garbage entering the first filter element 54 and extend the service life of the first filter element 54.

[0103] Optionally, the filter cover 522 is a metal filter cover, which has advantages such as high strength and long service life.

[0104] Optionally, the filter cover 522 is a stainless steel filter cover.

[0105] Optionally, the filter cover 522 includes a filter support 5221 and a filter 5222, with the filter 5222 disposed on the filter support 5221.

[0106] Optionally, the filter cover 522 includes a filter screen support 5221 and a filter screen 5222. The filter screen 5222 is detachably mounted on the filter screen support 5221, allowing for easy removal, cleaning, and replacement. Optionally, the filter cover 522 is conical. The conical shape of the filter cover 522 makes it difficult for debris to adhere, facilitating cleaning and allowing debris already attached to it to slide down to a lower position on the upper surface of the bottom shell 52, thus facilitating debris collection.

[0107] Optionally, the filter cover 522 is cylindrical, and the filter holes can cover the outer peripheral wall of the filter cover 522. This not only provides a wide adsorption surface but also makes it difficult for garbage to adhere, making it easy to clean.

[0108] Optionally, the outer peripheral wall of the filter cover 522 is transitionally connected to the outer peripheral wall of the convex ring 521; this facilitates cleaning of the connection between the filter cover 522 and the outer peripheral wall of the convex ring 521, and also facilitates the sliding of waste from the side wall of the filter cover 522 through the outer peripheral wall of the convex ring 521 to a lower position on the upper surface of the bottom shell 52, thereby facilitating waste collection.

[0109] Optionally, a first filter element 54 is provided on the side of the bottom shell 52 away from the dust can 51. The first filter element 54 is beneficial for secondary filtration of smaller waste that has been filtered by the filter cover 522, thereby ensuring the filtration effect.

[0110] Optionally, the first filter element 54 completely covers the inner ring hole 5211 of the convex ring 521, which enables secondary filtration of the waste passing through the filter cover 522.

[0111] Optionally, the first filter element 54 can be detachably disposed on the side of the bottom shell 52 away from the dust canister 51, which facilitates the cleaning and replacement of the first filter element 54.

[0112] Optionally, the first filter element 54 is mounted on the filter element support 540, and the filter element support 540 is detachably connected to the side of the bottom shell 52 away from the dust can 51, which facilitates the cleaning and replacement of the first filter element 54.

[0113] Optionally, the air inlet channel 523 includes an air inlet and an air outlet. The air inlet is connected to the suction head, and the air outlet of the air inlet channel 523 is provided with a flexible baffle 5231. When the negative pressure inside the dust can 51 reaches a certain range, the flexible baffle 5231 will open under the action of negative pressure, so that the suction head of the hair removal device has sufficient negative pressure, which facilitates the smooth suction of the garbage into the dust can 51.

[0114] Optionally, the air inlet of the air inlet channel 523 penetrates the side of the bottom shell 52 away from the dust can 51, and the air outlet of the air inlet channel 523 is offset from the filter cover 522. This offset arrangement of the air outlet from the filter cover 522 helps to extend the path length required for waste to transfer from inside the dust can 51 to the filter cover 522, reducing the amount of waste reaching the filter cover 522. On the one hand, this reduces the amount of waste filtered by the filter cover 522. On the other hand, larger and heavier waste is more likely to fall onto the upper surface of the bottom shell 52 before entering the filter cover 522, thus preventing the filter cover 522 from being blocked. Moreover, since the amount of waste passing through the filter cover 522 is reduced, and mainly consists of small and lightweight waste, this helps to extend the service life of the first filter element 54.

[0115] Optionally, the air outlet of the air inlet channel 523 is lower than the filter cover 522, which can effectively prevent garbage from entering the filter cover 522, thereby preventing the filter cover 522 from being blocked and extending the service life of the first filter element 54.

[0116] Optionally, the outer peripheral wall of the protruding ring 521 is provided with a number of spaced limiting protrusions 524; the limiting protrusions 524 are more conducive to the adhesion of garbage, increase the difficulty of garbage transfer with negative pressure, reduce the amount of garbage spiraling upward with the air flow, reduce the amount of garbage filtered by the filter cover 522, avoid the filter cover 522 from being blocked, and extend the service life of the first filter element 54; the protruding ring 521 allows some garbage to fall to the bottom shell 52 without passing through the filter cover 522, thereby allowing more garbage to be stored inside the dust can 51, which in turn helps to improve the internal space utilization of the dust can 51, reduce the cleaning frequency of the dust can 51, and ensure normal use.

[0117] Optionally, the limiting protrusion 524 extends to the surface of the bottom shell 52; the limiting protrusion 524 is more conducive to the adhesion of garbage, increases the difficulty of garbage transfer with negative pressure, reduces the amount of garbage spiraling upward with the air flow, reduces the amount of garbage filtered by the filter cover 522, avoids the filter cover 522 from being blocked, and at the same time extends the service life of the first filter element 54.

[0118] Optionally, the first filter element 54 is a sponge filter element.

[0119] Optionally, the limiting protrusion 524 is spiral-shaped, with a longer extended surface, which facilitates the attachment of more waste. Moreover, the spiral-shaped limiting protrusion 524 is set at an angle to the spiral rise angle of the waste, which can weaken the adsorption effect of negative pressure on the waste, thereby facilitating the attachment of more waste.

[0120] Optionally, a handle 512 is provided on the outer wall of the dust canister 51; the handle 512 is convenient to grip and easy to operate.

[0121] Optionally, the handle 512 is located on the top of the outer peripheral wall of the dust can 51.

[0122] Optionally, the dust canister 51 is partially transparent, which facilitates observation of the waste collection inside the dust canister 51 and allows for timely cleaning.

[0123] Optionally, the dust canister 51 is completely transparent, which makes it easy to observe the garbage collection inside the dust canister 51 and facilitate timely cleaning.

[0124] Optionally, the bottom of the dust can 51 is provided with a plurality of spaced positioning parts 525, which are positioning protrusions or positioning cavities; this facilitates quick positioning between the dust can assembly 50 and the main unit 6.

[0125] Optionally, the bottom of the dust can 51 is provided with a plurality of spaced limiting parts 526, which are buckles or slots, so as to facilitate quick fixation and separation between the dust can assembly 50 and the host 6.

[0126] Optionally, the bottom surface of the bottom shell 52 is provided with a plurality of spaced positioning parts 525, which are positioning protrusions or positioning cavities; this facilitates quick positioning between the dust can assembly 50 and the main unit 6, and makes it easy to quickly fix and separate the dust can assembly 50 from the main unit 6.

[0127] Optionally, the bottom surface of the bottom shell 52 has a plurality of spaced limiting parts 526, which are buckles or slots, so as to facilitate quick fixation and separation between the dust can assembly 50 and the main unit 6.

[0128] See Figure 4 and 5 The dust can assembly 50 provided in this embodiment of the invention is detachably mounted on the host 6, and the host 6 is used to provide negative pressure to the dust can assembly 50.

[0129] The dust canister assembly 50 of the hair removal device provided in this embodiment of the invention can be used to collect waste. Since the dust canister 51 is sealed to the bottom shell 52, the waste will not fall into the environment after the dust canister assembly 50 is separated from the main unit 6. The dust canister assembly 50 can be separated from the main unit 6 as a whole and transferred to a preset position for opening. This ensures cleanliness and reduces the weight of the transfer part, making it convenient to transfer. Moreover, when the dust canister assembly 50 is inverted, the waste will automatically fall into the dust canister 51 for easy emptying. The filter cover 522 is set on the top of the convex ring 521, which is relatively high. This way, when the waste enters the dust canister 51, most of the waste will not be able to reach the filter cover 522 above the convex ring 521 due to insufficient lift. The position of 22 avoids the problem of filter holes in filter cover 522 being blocked. This ensures that filter cover 522 can be used normally even without enlarging the filter holes. Moreover, the protruding ring 521 restricts some garbage from entering the filter cover 522, reducing the amount of garbage passing through the filter cover 522, and thus reducing the amount of garbage entering the first filter element 54, thereby helping to extend the service life of the first filter element 54. The protruding ring 521 allows some garbage to fall to the bottom shell 52 without passing through the filter cover 522, allowing more garbage to be stored inside the dust can 51, thereby improving the utilization rate of the internal space of the dust can 51, reducing the frequency of cleaning the dust can 51, and ensuring normal use.

[0130] like Figures 16-20 As shown, to facilitate quick installation and separation of the dust can assembly 50 from the main unit 6, in this embodiment of the invention, a snap-fit ​​structure is provided between the dust can assembly 50 and the main unit 6. The snap-fit ​​structure includes:

[0131] First snap-fit ​​assembly 501 is disposed on dust can assembly 50;

[0132] The second latching component is movably mounted on the main unit 6, and its position on the main unit 6 is adjustable;

[0133] The dust can assembly 50 is fixed to the main unit 6 by a first snap-fit ​​assembly 501 and a second snap-fit ​​assembly;

[0134] The second driving member 7 is connected to the second latching assembly to drive the second latching assembly to move from a position engaged with the first latching assembly 501 to a position separated from the first latching assembly 501.

[0135] The hair removal device provided in this embodiment of the invention allows the dust canister assembly 50 to be quickly fixed to the main unit 6 using the first and second snap-fit ​​components. When separation is required, the second driving component 7 can drive the second snap-fit ​​component to move from the position where it is engaged with the first snap-fit ​​component 501 to the position where it is separated from the first snap-fit ​​component 501, thereby facilitating the quick separation of the dust canister assembly 50 from the main unit 6. This facilitates quick installation and separation of the dust canister assembly 50 from the main unit 6, improving the customer experience.

[0136] Optionally, the first latching assembly 501 includes a third latch 5111 and a fourth latch 5112 spaced apart, both of which are located at the bottom of the dust can assembly 50;

[0137] The second latching assembly includes a fifth latch 6110 and a sixth latch 6120 spaced apart. The fifth latch 6110 is disposed on the first transmission arm 611, and the sixth latch 6120 is disposed on the second transmission arm 612. Both the first transmission arm 611 and the second transmission arm 612 are movably disposed on the main unit 6. The fifth latch 6110 is used to engage with the third latch 5111, and the sixth latch 6120 is used to engage with the fourth latch 5112.

[0138] The second driving component 7 is connected to the first transmission arm 611 and the second transmission arm 612 respectively.

[0139] The first drive arm 611 and the second drive arm 612 can respectively drive the fifth latch 6110 and the sixth latch 6120 to move. In this way, the second drive member 7 drives the first drive arm 611 and the second drive arm 612 to move simultaneously, so that the fifth latch 6110 and the sixth latch 6120 can move accordingly. This makes it easier for the fifth latch 6110 and the sixth latch 6120 to separate from the third latch 5111 and the fourth latch 5112, thereby facilitating the separation of the dust can assembly 50 from the main unit 6.

[0140] Optionally, the first transmission arm 611 and the second transmission arm 612 are rotatably connected to the main unit 6, respectively;

[0141] The first transmission arm 611 and the second transmission arm 612 are spaced apart, with one end of the first transmission arm 611 close to one end of the second transmission arm 612.

[0142] The second drive unit 7 is movably connected to the host 6, and the second drive unit 7 is connected to one end of the first transmission arm 611 and one end of the second transmission arm 612 respectively.

[0143] The fifth buckle 6110 is located at the other end of the first transmission arm 611, and the sixth buckle 6120 is located at the other end of the second transmission arm 612.

[0144] The second driving member 7 drives the first transmission arm 611 and the second transmission arm 612 to rotate relative to the main unit 6, thereby changing the position of the other end of the first transmission arm 611 and the other end of the second transmission arm 612. This causes the positions of the fifth latch 6110 at the other end of the first transmission arm 611 and the sixth latch 6120 at the other end of the second transmission arm 612 to move. When the fifth latch 6110 moves from the position engaged with the third latch 5111 to the position separated from the first latch assembly 501, and the sixth latch 6120 moves from the position engaged with the fourth latch 5112 to the position separated from the fourth latch 5112, the dust can assembly 50 can be smoothly separated from the main unit 6.

[0145] Optionally, a first reset member 6111 is provided on the first transmission arm 611. The first reset member 6111 elastically abuts against the first transmission arm 611 to restrict the first transmission arm 611 from moving with the second drive member 7. One end of the first reset member 6111 abuts against the first transmission arm 611, and the other end abuts against the host 6.

[0146] The second transmission arm 612 is provided with a second reset member 6121. The second reset member 6121 elastically abuts against the second transmission arm 612 to restrict the movement of the second transmission arm 612 with the second drive member 7. One end of the second reset member 6121 abuts against the second transmission arm 612, and the other end abuts against the main unit 6.

[0147] The second driving member 7 is provided with a third reset member 70. The third reset member 70 elastically abuts against the second driving member 7 to drive the second driving member 7 to reset. One end of the third reset member 70 abuts against the second driving member 7, and the other end abuts against the host 6.

[0148] The second driving component 7 can drive the second latching assembly to move, thereby facilitating the separation of the first latching assembly 501 from the second latching assembly. The first reset assembly, the second reset assembly, and the third reset assembly can respectively drive the fifth latch 6110, the sixth latch 6120, and the second driving component 7 to reset. In this way, each time the dust can assembly 50 is separated from the main unit 6, the second latching assembly and the second driving component 7 will reset, that is, the second latching assembly will move back to the position where it can engage with the first latching assembly 501, which facilitates the quick engagement of the dust can assembly 50 and the main unit 6 in the future.

[0149] Optionally, the first reset member 6111, the second reset member 6121, and the third reset member 70 are all springs.

[0150] Optionally, both the first transmission arm 611 and the second transmission arm 612 are bow-shaped transmission arms; the second buckle assembly formed by the first transmission arm 611, the second driving member 7, and the second transmission arm 612 is generally semi-circular.

[0151] Optionally, the first transmission arm 611 is provided with a first guide surface 6112, and the second driving member 7 is provided with a second guide surface 71, with the first guide surface 6112 and the second guide surface 71 slidingly engaged.

[0152] The second transmission arm 612 is provided with a third guide surface 6122, and the second driving member 7 is provided with a fourth guide surface 73. The third guide surface 6122 and the fourth guide surface 73 are in sliding engagement.

[0153] When the second driving member 7 moves, the second guide surface 71 and the fourth guide surface 73 of the second driving member 7 can respectively cooperate with the first guide surface 6112 on the first transmission arm 611 and the third guide surface 6122 on the second transmission arm 612 and drive the first transmission arm 611 and the second transmission arm 612 to move. In this way, the second driving member 7 can drive the first transmission arm 611 and the second transmission arm 612 to move quickly, thereby enabling the second latching assembly to move quickly from the position of being engaged with the first latching assembly 501 to the position of being separated from the first latching assembly 501, thereby realizing the rapid separation of the dust can assembly 50 from the main unit 6.

[0154] Optionally, a first extended surface 6113 is provided at the bottom of the first guide surface 6112.

[0155] The bottom of the second guide surface 71 is provided with a second straight extension surface 72.

[0156] The second guide surface 71 is located above the first guide surface 6112; the first extended surface 6113 abuts against the second extended surface 72; the abutment between the first extended surface 6113 and the second extended surface 72 restricts the first transmission arm 611 from moving towards the second driving member 7; when the second driving member 7 moves downward, the second guide surface 71 on the second driving member 7 will push the first transmission arm 611 away from the second driving member 7 by pressing against the first guide surface 6112, thereby causing the position of the fifth buckle 6110 at the other end of the first transmission arm 611 to deviate, making it easier for the fifth buckle 6110 to disengage from the third buckle 5111.

[0157] The bottom of the third guide surface 6122 is provided with a third straight extension surface 6123.

[0158] The bottom of the fourth guide surface 73 is provided with a fourth straight extension surface 74.

[0159] The fourth guide surface 73 is located above the third guide surface 6122, and the third straight surface 6123 abuts against the fourth straight surface 74. The third straight surface 6123 abuts against the second straight surface 72, which can limit the distance that the second transmission arm 612 moves toward the second driving member 7. When the second driving member 7 moves downward, the fourth guide surface 73 on the second driving member 7 drives the second transmission arm 612 to move away from the second driving member 7 by pressing against the third guide surface 6122, thereby causing the position of the sixth latch 6120 at the other end of the second transmission arm 612 to deviate, so that the sixth latch 6120 can be disengaged from the fourth latch 5112. When the fifth latch 6110 and the sixth latch 6120 are separated from the third latch 5111 and the fourth latch 5112 respectively, the dust can assembly 50 and the main unit 6 can be freely separated.

[0160] Optionally, the second driving member 7 includes a sliding plate 7a, and a button hole 75 is provided on one side of the sliding plate 7a;

[0161] A first extension 76 is provided on the other side of the sliding plate 7a, and a second guide surface 71 is provided on the first extension 76.

[0162] A second extension 77 is also provided on the other side of the sliding plate 7a. The first extension 76 and the second extension 77 are spaced apart, and the fourth guide surface 73 is provided on the second extension 77.

[0163] The main unit 6 is provided with a slide groove 610, and the sliding plate 7a is slidably disposed in the slide groove 610; the second drive unit 7 controls the movement of the first transmission arm 611 and the second transmission arm 612 through the sliding plate 7a, which is convenient to operate and has strong stability; the button hole 75 is set to facilitate the operator's fingers to insert and apply force, which is convenient to operate.

[0164] Optionally, a cover plate 62 is also provided above the second buckle assembly. The cover plate 62 is fixed on the host 6. A first slot 621 is provided at the position corresponding to the fifth buckle 6110, and a second slot 622 is provided at the position corresponding to the sixth buckle 6120.

[0165] The cover plate 62 is also provided with a number of spaced positioning grooves 623, and the bottom of the dust tank assembly 50 is provided with positioning posts 5012 that cooperate with the positioning grooves 623;

[0166] A second filter element 63 is provided in the middle of the cover plate 62, and the second filter element 63 corresponds to the area between the first transmission arm 611 and the second transmission arm 612.

[0167] The main unit 6 has a built-in air extraction motor, which is located below the second filter element 63.

[0168] Optionally, the second filter element 63 is a HEPA filter element.

[0169] On the one hand, the cover plate 62 can protect the second buckle assembly and the second drive component 7. On the other hand, the first slot 621 and the second slot 622 can limit the third buckle 5111 and the fourth buckle 5112, preventing the dust can assembly 50 from moving with the first drive arm 611 and the second drive arm 612 when the first drive arm 611 and the second drive arm 612 move, thereby affecting the normal separation of the dust can assembly 50 from the main unit 6.

[0170] The snap-fit ​​structure provided in this embodiment of the invention has a first snap-fit ​​component 501 disposed at the bottom of the dust can assembly 50, and a second snap-fit ​​component disposed at the top of the main unit 6.

[0171] The hair removal device provided in this embodiment of the invention allows the dust canister assembly 50 to be quickly fixed to the main unit 6 using the first and second snap-fit ​​components. When separation is required, the second snap-fit ​​component 7 can drive the second snap-fit ​​component to move from the position where it is engaged with the first snap-fit ​​component 501 to the position where it is separated from the first snap-fit ​​component 501, thereby facilitating the quick separation of the dust canister assembly 50 from the main unit 6. This facilitates the quick installation and separation of the dust canister assembly 50 from the main unit 6, improving the customer experience. Example

[0172] See Figures 1-8 The hair removal device provided in this embodiment of the invention includes a hair suction assembly, which includes: a suction housing 11, the suction housing 11 having a suction channel 12, the suction channel 12 including an air inlet 121 and an air outlet 122, the air inlet 121 penetrating one end of the suction housing 11, and the air outlet 122 penetrating the other end of the suction housing 11.

[0173] The limiting plate 2 is set on the outer wall of the end of the air extraction housing 11 where the air inlet 121 is located. The limiting plate 2 has a strip-shaped through hole that passes through the two opposite sides of the limiting plate 2.

[0174] Comb 3, comb 3 slides with the through hole, comb 3 includes a combing part 31 for combing hair and a support part 32 for supporting the combing part 31. The combing part 31 passes through the limiting plate 2 and extends to the side of the air inlet 121. After the comb 3 is engaged with the limiting plate 2, when hair is attached to the comb 3, the comb 3 can be moved relative to the limiting plate 2. The limiting plate 2 blocks the hair attached to the comb 3, allowing the hair to move relative to the comb 3, thereby facilitating the separation of the hair attached to the comb 3 from the comb 3.

[0175] The first driving component 4 includes a transmission rod 42. One end of the transmission rod 42 is hinged to the side wall of the air extraction housing 11. A second limiting groove 321 is provided on the support part 32. The other end of the transmission rod 42 is movably disposed in the second limiting groove 321. After the transmission rod 42 is hinged to the air extraction housing 11, it forms a lever structure for driving the comb 3 to move.

[0176] The first driving component 4 also includes a spring 41, one end of which abuts against the transmission rod 42, and the other end of which abuts against the side wall of the vacuum housing 11.

[0177] The movement directions of the comb 3 are defined as the first direction X and the second direction X1, which are opposite to each other. When the comb 3 moves in the first direction X, the distance that the combing part 31 passes through the limiting plate 2 increases. When the comb 3 moves in the second direction X1, the distance that the combing part 31 passes through the limiting plate 2 decreases. The spring 41 has a tendency to move the comb 3 along the first direction X, which maximizes the distance that the combing part 31 passes through the limiting plate 2, thus facilitating combing. Pressing down the transmission rod 42 causes the comb 3 to move in the second direction X1. The transmission rod 42 can cause the comb 3 to overcome the rebound effect of the spring 41, minimizing the distance that the combing part 31 extends beyond the limiting plate 2, or even preventing it from extending beyond the limiting plate 2, thus facilitating the separation of hair attached to the combing part 31 from the combing part 31.

[0178] After the hair removal device provided in this embodiment is connected to the air extraction structure 5, the air inlet 121 of the air extraction channel 12 on its air extraction housing 11 can be used to extract hair, and the air outlet 122 is used to connect to the air extraction structure 5. The limiting plate 2 can restrict the movement of hair attached to the comb 3 relative to the comb 3. Therefore, during the combing process, if hair is attached to the comb 3, the comb 3 can be moved relative to the limiting plate 2, so that the comb 3 and the hair move relative to each other, thereby separating the hair from the comb 3 and sucking it into the air extraction structure 5 through the corresponding air inlet 121. The comb 3 is set in the air inlet. On one side of the mouth 121, when the comb 3 combs the hair, some detached hair is sucked into the mouth, transferred and collected, preventing hair from scattering into the environment during hair removal, thus ensuring a clean and tidy environment. The transmission rod 42 is hinged to the suction housing 11 to form a corresponding lever structure. By pressing down the transmission rod 42, the comb 3 can be moved in the second direction X1, which facilitates the separation of hair on the combing part 31 from the comb 3. The spring 41 helps to drive the comb 3 and the transmission rod 42 to return to their original positions, maximizing the distance the comb 3 extends beyond the limiting plate 2, thus facilitating hair combing. The combination of the transmission rod 42 and the spring 41 is not only low in cost, but also simple in structure and highly stable. The suction structure 5 consists of a dust can assembly 50 and a main unit 6. The dust can assembly 50 can be used to collect and filter hair, while the main unit 6 has a built-in suction motor that can provide negative pressure for the hair suction assembly and the dust can assembly 50. Example

[0179] See Figures 10-15 This invention provides a hair removal device, which includes a dust can assembly 50. The dust can assembly 50 is disposed on the main unit 6 and is used to collect and filter waste, including dust, hair, etc. The dust can assembly 50 includes:

[0180] Dust canister 51, the interior of dust canister 51 is hollow, the top and sides of dust canister 51 are closed, and the bottom is open 511;

[0181] The dust canister 51 is completely transparent, making it easy to observe the amount of waste inside and to empty it promptly.

[0182] The inner walls of dust can 51 are all smooth surfaces, which makes it difficult for garbage to adhere and makes cleaning easier;

[0183] The top of the dust can 51 is shaped like an inverted bowl, while the middle and bottom are hollow cylinders. The top and inner walls of the dust can 51 have a smooth transition. The internal structure of the dust can 51 is not conducive to the adhesion of garbage and is easy to clean.

[0184] Bottom shell 52 is disposed at the bottom opening 511 of dust can 51. Bottom shell 52 is sealed to dust can 51. One end of bottom shell 52 is rotatably connected to dust can 51, and the other end of bottom shell 52 is elastically snapped to dust can 51.

[0185] A convex ring 521 is integrally formed on the bottom shell 52. The axis of the convex ring 521 is set in the vertical direction. The convex ring 521 protrudes from the upper surface of the bottom shell 52. The convex ring 521 increases the height of the filter cover 522, increases the difficulty for garbage to enter the filter cover 522, reduces the amount of garbage entering the filter cover 522, thereby avoiding garbage screen blockage. The inner ring hole 5211 of the convex ring 521 penetrates the bottom of the bottom shell 52. The convex ring 521 is conical.

[0186] A filter cover 522 is disposed on top of a convex ring 521. Filter holes are provided on the top and / or sidewalls of the filter cover 522. An opening 511 is provided at the bottom of the filter cover 522, which communicates with the inner ring hole 5211 of the convex ring 521. The filter cover 522 is conical in shape, and its outer peripheral wall is transitionally connected to the upper end of the outer peripheral wall of the convex ring 521. The conical shape of the filter cover 522 and the convex ring 521 is not conducive to the adhesion of garbage and is easy to clean.

[0187] An air inlet channel 523 is provided on the bottom shell 52. One end of the air inlet channel 523 is connected to the inside of the dust tank 51, and the other end of the air inlet channel 523 is connected to the bottom of the bottom shell 52.

[0188] The dust canister assembly 50 of the hair removal device provided in this embodiment of the invention can be used to collect dust, hair, and other waste. Since the dust canister 51 is sealed to the bottom shell 52, dust will not fall into the environment after the dust canister assembly 50 is separated from the main unit 6. The dust canister assembly 50 can be separated from the main unit 6 as a whole and transferred to a preset position for opening. This ensures cleanliness and reduces the weight of the transfer part, facilitating transfer. Furthermore, when the dust canister assembly 50 is inverted, the waste will automatically fall from the bottom shell 52 into the dust canister 51, making it easy to empty. The bottom shell 52 is hinged to the dust canister 51. When opened, the bottom shell 52 will essentially flip over the dust canister 51, but the bottom shell 52 is only partially separated from the dust canister 51. This prevents the bottom shell 52 from easily opening after the dust canister 51 is opened. Regarding the issue of loss: The filter cover 522 is located on top of the convex ring 521. The high position of the filter cover 522 ensures that when waste enters the dust canister 51, most of it will not reach the filter cover 522 above the convex ring 521 due to insufficient lift. This prevents the filter holes of the filter cover 522 from becoming clogged. Even without enlarging the filter holes, the filter cover 522 can still function normally. Furthermore, the upward bulge increases the height of the filter cover 522, raising the height requirement for waste to enter it. This limits the amount of waste entering the filter cover 522, reducing the amount of waste passing through it and consequently reducing the amount of waste entering the first filter element 54, thus extending its service life. Example

[0189] See Figures 16-20 This invention provides a hair removal device. To facilitate quick installation and separation of the dust can assembly 50 from the main unit 6, a snap-fit ​​structure is provided between the dust can assembly 50 and the main unit 6. This snap-fit ​​structure includes:

The second latching assembly includes a first transmission arm 611 and a second transmission arm 612. The first transmission arm 611 is provided with a fifth latch 6110 for engaging with the third latch 5111, and the second transmission arm 612 is provided with a sixth latch 6120 for engaging with the fourth latch 5112. Both the first transmission arm 611 and the second transmission arm 612 are rotatably connected to the main unit 6.

[0192] The dust can assembly 50 is fixed to the main unit 6 by a first snap-fit ​​assembly 501 and a second snap-fit ​​assembly;

[0193] The second driving member 7 is connected to one end of the first transmission arm 611 and one end of the second transmission arm 612 respectively. The fifth buckle 6110 is provided at the other end of the first transmission arm 611, and the sixth buckle 6120 is provided at the other end of the second transmission arm 612.

[0194] In the hair removal device of this embodiment, the third and fourth latches 5111 and 5112 at the bottom of the dust can assembly 50, and the fifth and sixth latches 6110 and 6120 on the main unit 6, enable the dust can assembly 50 to quickly engage with the main unit 6, thereby fixing the dust can assembly 50 to the main unit 6. When the dust can assembly 50 and the main unit 6 need to be separated, the first transmission arm 611 and the second transmission arm 612 can be moved by the second drive component 7, so that the fifth latch 6110 disengages from the position engaged with the third latch 5111, and the sixth latch 612 disengages from the position engaged with the fourth latch 5112, thereby enabling the dust can assembly 50 to quickly separate from the main unit 6 and improving the customer experience.
