Description

Hair collection device Technical Field

[0001] The present application relates to the technical field of suction equipment, and in particular to a hair collection device. Background Art

[0002] With the development of social economy and the improvement of residents' living standards, pets have become the choice of more and more people. Although pets can accompany their owners and reduce loneliness, they also have some problems, such as hair loss. At present, people usually use hair collection devices to absorb and collect the hair dropped by pets, but there is a problem with the hair collection devices in the prior art: since the air outlet of the hair collection device is usually set at the bottom end of the shell of the hair collection device, and the bottom end of the shell of the hair collection device is provided with a foot pad, there will be a gap between the bottom end of the shell of the hair collection device and the use platform (such as a desktop or the ground), so the wind discharged from the air outlet will blow out from the above gap, thereby generating a large noise, resulting in a poor user experience.

[0003] Summary of the Invention

[0004] In a first aspect, an embodiment of the present application provides a hair collection device, comprising: a shell, the shell being provided with an inner cavity, and the shell being provided with an exhaust port connected to the inner cavity; an air inlet pipe, the air inlet pipe being provided on the shell and connecting the inner cavity with the outside; a fan, the fan being provided in the inner cavity; an air outlet plate, the air outlet plate being provided at the exhaust port, the air outlet plate being provided with air outlet holes, and the air outlet holes connecting the inner cavity with the outside; and an air guide plate, the air guide plate being provided on a side of the air outlet plate facing away from the inner cavity; the air guide plate and the air outlet plate being spaced apart to jointly constitute an air outlet channel, and the opening direction of the air outlet channel is different from the hole axis direction of the air outlet.

[0005] In the hair collection device provided in this embodiment, an air guide plate is provided on the side of the air outlet plate facing away from the inner cavity, and an air outlet channel is formed by spacing the air guide plate and the air outlet plate.

[0028] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0029] Referring to Figures 1-3, an embodiment of the present application provides a hair collection device 100. The hair collection device 100 is a device with a suction function that can be used to collect pet hair for a cleansing effect. During use, the user must place the hair collection device 100 upright on a work surface (e.g., a tabletop or the floor) and ensure that the hair collection device 100 remains stable and motionless. In the description of this application, in this state, the end of the hair collection device 100 closest to the work surface is defined as the bottom end of the hair collection device 100.

[0030] The hair collection device 100 includes a housing 11, an air inlet pipe 13, a fan 15 (see Figure 6), and an air outlet plate 17. The housing 11 can be a plastic shell, which has the advantages of being sturdy and lightweight. The housing 11 is provided with an inner cavity 111, which is used to accommodate other components of the hair collection device 100 installed inside the housing 11, such as a circuit board. The air inlet pipe 13 is a channel for air to enter the housing 11. The air inlet pipe 13 is provided on the housing 11 and connects the inner cavity 111 with the outside. In this embodiment, one end of the air inlet pipe 13 is located outside the housing 11, and the other end is inserted into the interior of the housing 11. In other embodiments, one end of the air inlet pipe 13 may be located outside the housing 11, and the other end may be connected to the surface of the housing 11. The fan 15 is provided in the inner cavity 111 to provide suction power for the hair collection device 100.

[0031] Referring to Figures 3-5 , the housing 11 is provided with an exhaust vent 113, which connects the inner cavity 111 with the exterior of the housing 11, allowing airflow within the inner cavity 111 to exit the housing 11. In this embodiment, the housing 11 also includes a bottom wall 115 and a foot pad 117. The bottom wall 115 is a sidewall located at the bottom end of the housing 11, and the exhaust vent 113 is disposed on the bottom wall 115. When the hair collection device 100 is in use, the exhaust vent 113 faces a work surface (e.g., a tabletop or the floor). The foot pad 117 is disposed on the surface of the bottom wall 115 facing away from the inner cavity 111 and serves to support the housing 11, thereby spacing the bottom wall 115 from the work surface and preventing direct contact and friction between the bottom wall 115 and the work surface. An air outlet plate 17 is disposed at the exhaust vent 113 and is detachably connected to the housing 11. In this embodiment, the air outlet plate 17 is connected to the housing 11 via bolts. In other embodiments, the air outlet plate 17 can also be snapped into place with the housing 11 by means of a snap fit and a slot. The air outlet plate 17 completely covers the air outlet 113 and is provided with an air outlet hole 171 that connects the inner cavity 111 with the outside world, allowing the airflow within the housing 11 to be discharged to the outside world.

[0032] The hair collection device 100 also includes an air deflector 19, which is positioned on the side of the air outlet plate 17 facing away from the inner cavity 111. The air deflector 19 is spaced at least partially from the air outlet plate 17 to form an air outlet channel 191. The air deflector 19 is connected to the rest of the air outlet plate 17. This specification does not limit the connection method between the air deflector 19 and the air outlet plate 17; the air deflector 19 can be fixedly connected, detachably connected, directly connected, or indirectly connected to the air outlet plate 17.

[0033] Please refer to Figure 4. The air outlet plate 17 includes a connecting portion 175 and a spacer 177. The connecting portion 175 is arranged at the edge of the spacer 177, and the connecting portion 175 is used to connect to the bottom wall 115 and the air guide plate 19. The spacer 177 and the air guide plate 19 are spaced apart to form an air outlet channel 191. In this specification, there is no limitation on the specific shapes of the connecting portion 175 and the spacer 177. In this embodiment, the spacer 177 is an arc-shaped plate protruding toward the inner cavity 111. In other embodiments, the spacer 177 can also be a folded plate, a bent plate or a special-shaped plate protruding toward the inner cavity 111, as long as there is a gap between the spacer 177 and the air guide plate 19. In this embodiment, the connecting portion 175 is a U-shaped bar arranged along the edge of the spacer 177. In other embodiments, the connecting portion 175 can also be a curved bar, a straight bar or a broken line arranged along the edge of the spacer 177.

[0034] The air outlet channel 191 is a channel for the air flow to flow between the air outlet plate 17 and the air guide plate 19. The air outlet channel 191 is provided with an opening. The opening direction of the air outlet channel 191 is different from the hole axis direction of the exhaust port 113 to prevent the air flow from blowing out of the opening of the air outlet channel 191 and blowing directly toward the use platform. In this specification, the "opening direction" of the air outlet channel 191 should be understood as the direction in which the air flow is discharged from the air outlet channel 191. In this embodiment, the opening direction of the air outlet channel 191 is a horizontal direction (the surface of the use platform is selected as the reference horizontal plane). In other embodiments, the opening direction of the air outlet channel 191 can also be any direction away from the use platform.

[0035] With the above arrangement, when the hair collection device is in operation, external air flows through the air inlet pipe 13 into the interior of the housing 11, then passes through the fan 15 and through the air outlet holes 171 into the air outlet channel 191, and is finally discharged to the outside through the air outlet channel 191. Due to the provision of the air guide plate 19, the air guide plate 19 can redirect the air discharged from the air outlet plate 17, thereby preventing the air from being blown directly onto the user platform and then out through the gap between the user platform and the bottom wall 115, which would generate a lot of noise. Therefore, the hair collection device 100 of this embodiment has the advantage of low exhaust noise.

[0036] Referring to Figures 3 and 4 , in this embodiment, a snap-fit ​​groove 173 is defined on the surface of the air outlet plate 17 facing away from the inner cavity 111. The snap-fit ​​groove 173 is located on the side of the connecting portion 175 facing away from the inner cavity 111. A snap-fit ​​member is provided on the edge of the air guide plate 19 to engage with the snap-fit ​​groove 173. The snap-fit ​​engagement of the snap-fit ​​member with the snap-fit ​​groove 173 enables the air guide plate 19 to be detachably connected to the air outlet plate 17. In other embodiments, the air guide plate 19 can also be bonded to the air outlet plate 17, bolted, or glued, as long as the air guide plate 19 and the air outlet plate 17 do not separate due to vibration during use of the hair collection device.

[0037] Referring to Figures 5-7, in some embodiments, the hair collection device 100 further includes a fan housing 21. The fan housing 21 is used to protect the fan 15 and further achieve noise reduction. The fan housing 21 is fixedly disposed in the inner cavity 111, for example, by being clipped or bolted to the housing 11. The fan housing 21 includes an air inlet end 211 and an air outlet end 212. The air inlet end 211 is the end where air enters the fan housing 21, and the air outlet end 212 is the end where air exits the fan housing 21. When the hair collection device 100 is in operation, air flows through the fan housing 21 from the air inlet end 211 into the interior of the fan housing 21 and exits the fan housing 21 from the air outlet end 212.

[0038] The fan housing 21 includes an outer cover 214 and an inner cover 213 . The inner cover 213 is disposed inside the outer cover 214 . The inner cover 213 and the outer cover 214 are spaced apart from each other. The fan 15 is disposed in the fan housing 21 and inside the inner cover 213 .

[0039] In this embodiment, both the inner cover 213 and the outer cover 214 are cylindrical structures. It is stipulated that the end of the outer cover 214 / inner cover 213 close to the bottom wall 115 is the bottom end, and the end away from the bottom wall 115 is the top end. The top end of the outer cover 214 is provided with an opening and the bottom end is closed. The bottom end of the inner cover 213 is connected to the bottom end of the outer cover 214. The top end of the inner cover 213 is provided with an opening to form the above-mentioned air inlet end 211. A first through hole 2131 is provided on the side wall of the inner cover 213, and the first through hole 2131 connects the inner cover 213 with the outer cover 214. In this embodiment, the number of the first through hole 2131 is one. In other embodiments, the number of the first through hole 2131 can be multiple. A second through hole 2141 is provided on the side wall of the outer cover 214 to form the above-mentioned air outlet end 212.

[0040] With the above arrangement, when the hair collection device 100 is in operation, airflow within the housing 11 first enters the inner housing 213 through the air inlet end 211, then passes through the first through-hole 2131 into the gap between the inner housing 213 and the outer housing 214, and finally exits the fan housing 21 through the second through-hole 2141. The presence of the fan housing 21 prolongs the airflow path within the inner cavity 111, thereby reducing wind force and achieving a noise reduction effect. In this embodiment, multiple second through-holes 2141 are arranged in an array on the sidewalls of the outer housing 214, thereby diverting the airflow and further reducing wind force, thereby reducing noise generation. In other embodiments, the number of second through-holes 2141 may also be one. Furthermore, in this embodiment, the first through hole 2131 is disposed on the side of the inner cover 213 facing away from the second through hole 2141. Therefore, after the airflow passes through the first through hole 2131, it travels a relatively long distance between the inner cover 213 and the outer cover 214, thereby reducing the wind force and achieving a noise reduction effect. In other embodiments, the first through hole 2131 may also be disposed at other locations within the inner cover 213, as long as the axis of the first through hole 2131 is aligned with the axis of the second through hole 2141 to prevent the airflow from the first through hole 2131 from passing directly through the second through hole 2141 and exiting the fan housing 21, thereby reducing the noise reduction effect of the fan housing 21.

[0041] Referring to Figures 6 and 7 , the fan housing 21 also includes a first air-permeable, sound-absorbing layer 215. This layer is made of a material that exhibits both air-permeability and sound-absorbing properties, such as a noise-reducing sponge. The first air-permeable, sound-absorbing layer 215 is interposed between the outer cover 214 and the inner cover 213. This arrangement allows the first air-permeable, sound-absorbing layer 215 to absorb not only the noise generated by the airflow within the fan housing 21 but also the noise generated by the fan 15 during operation, thereby enhancing the noise reduction effectiveness of the fan housing 21.

[0042] The fan housing 21 also includes a second air-permeable, sound-absorbing layer 216. This layer is made of a material that exhibits both air-permeability and sound-absorbing properties, such as a noise-reducing sponge. This layer fills the gap between the inner cover 213 and the fan 15. This arrangement not only absorbs the noise generated by the airflow within the fan housing 21, but also absorbs the noise generated by the fan 15 during operation, further enhancing the noise reduction effectiveness of the fan housing 21.

[0043] In this embodiment, both the first air-permeable and sound-absorbing layer 215 and the second air-permeable and sound-absorbing layer 216 are provided. In other embodiments, the first air-permeable and sound-absorbing layer 215 may be provided only between the outer cover 214 and the inner cover 213, or the second air-permeable and sound-absorbing layer 216 may be provided only between the inner cover 213 and the fan 15.

[0044] 6 and 7 , the fan housing 21 further includes a filter 217, which is disposed at the top of the inner housing 213. In some embodiments, the filter 217 covers the opening between the inner housing 213 and the outer housing 214, and the filter 217 communicates only with the inner cavity of the inner housing 213. This arrangement allows air to be filtered by the filter 217 before entering the fan housing 21, thereby filtering and trapping foreign matter such as pet hair carried in the air. This prevents foreign matter from entering the fan housing 21 and potentially causing malfunction of the fan 15 or clogging the first and second through-holes 2131, 2141.

[0045] Referring to Figure 5 , the hair collection device further includes an air guide 23 disposed within the inner cavity 111. The air guide 23 includes an air channel 231, which communicates with one end of the air inlet pipe 13 located within the inner cavity 111. The air guide 23 also includes an air guide opening 233, which is an opening at one end of the air channel 231 away from the air inlet pipe 13. The opening direction of the air guide opening 233 defines the direction in which air flows out of the air channel 231, and the opening direction of the air guide opening 233 faces the fan housing 21. This arrangement allows the air guide 23 to guide the airflow exiting the air inlet pipe 13, quickly directing it toward the filter element 217 and into the fan housing 21, thereby providing drainage.

[0046] The working principle of the hair collection device provided in this embodiment is as follows: when in use, the user first places the hair collection device 100 upright on a usage platform (such as the ground / table), and then starts the fan 15 to start suctioning air. The external airflow enters the air guide 23 from the suction pipe 13 and is blown to the filter 217 through the air guide port 231. The filter 217 filters impurities such as pet hair entrained in the airflow. The filtered airflow enters the inner cover 213, then passes through the second air-permeable and sound-absorbing layer 216 and the first through-hole 2131 to enter between the inner cover 213 and the outer cover 214, and then passes through the first air-permeable and sound-absorbing layer 215 and the second through-hole 2141 to be discharged from the fan housing 21. Then, the airflow enters the air outlet channel 191 through the air outlet hole 171, and is blown to the outside from the air outlet channel 191 under the guidance of the air guide plate 19, completing the exhaust. During the above process, the fan housing 21 can reduce the noise of the airflow in the inner cavity 111, and the air deflector 19 changes the airflow direction of the hair collection device 100, preventing the airflow from the hair collection device 100 from blowing directly onto the use platform and being blown out through the gap between the use platform and the hair collection device 100, thereby generating loud noise. In summary, the hair collection device 100 provided in this embodiment can reduce the noise generated during use, achieving the beneficial effects of low noise and a good user experience.

[0047] Referring to Figures 8 to 11 , another embodiment of the present application provides a hair collection device 100a. The hair collection device 100a includes a housing 10a, a fan filter assembly 30a, and an air duct assembly 80a. The fan filter assembly 30a and the air duct assembly 80a are both assembled within the housing 10a. In some embodiments, the hair collection device 100a has an air inlet 71a, a hair receiving chamber 140a, an air outlet 15a, etc. The air duct assembly 80a can connect the air inlet 71a and the hair receiving chamber 140a, and the fan filter assembly 30a can connect the hair receiving chamber 140a and the air outlet 15a. In which, during the normal operation of the hair collection device 100a, the fan filter assembly 30a can form a pressure difference between the hair receiving chamber 140a and the external atmospheric pressure, so that the external air can be sucked into the hair receiving chamber 140a from the air inlet 71a through the air duct assembly 80a, and can be discharged from the air outlet 15a to the outside of the hair collection device 100a after being filtered by the fan filter assembly 30a.

[0048] The housing 10a has an inner annular wall 11a, with the fan filter assembly 30a and the air duct assembly 80a located radially opposite the inner annular wall 11a. This helps separate the fan filter assembly 30a from the air duct assembly 80a, preventing them from being too close together. This helps prevent hair from falling from the fan filter assembly 30a onto the air duct assembly 80a due to their proximity. It also helps balance the weight of the hair collection device 100a radially along the inner annular wall 11a. The hair collection device 100a provided in this embodiment utilizes the inner annular wall 11a formed by the shape of the housing 10a to separate the fan filter assembly 30a from the air duct assembly 80a, ensuring that the fan filter assembly 30a and the air duct assembly 80a are more reasonably positioned within the housing 10a.

[0049] In some embodiments, the housing 10a may further include an outer annular wall 12a, and the fan filter assembly 30a may be located between the inner annular wall 11a and the outer annular wall 12a. The air duct assembly 80a may be located between the inner annular wall 11a and the outer annular wall 12a. The hair receiving chamber 140a may be located between the inner annular wall 11a and the outer annular wall 12a. The air inlet 71a may be located on the outer annular wall 12a or elsewhere on the hair collection device 100a. The air outlet 15a may be located on the outer annular wall 12a or elsewhere on the hair collection device 100a.

[0050] In some embodiments, the outer shell 10a can be generally annular. For example, the outer shell 10a can be generally circular, elliptical, triangular, quadrilateral, pentagonal, hexagonal, heptagonal, octagonal, or enneagonal. In some embodiments, the inner annular wall 11a of the outer shell 10a can enclose an inner annular space 110a. The inner annular space 110a can be generally cylindrical, elliptical, triangular, quadrilateral, pentagonal, hexagonal, heptagonal, octagonal, or enneagonal.

[0051] In some embodiments, the shape of the outer shell 10a and the shape of the inner annular space 110a can be substantially the same or different. For example, if the outer shell 10a is substantially annular, the inner annular space 110a can be substantially cylindrical, elliptical, triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal, or enneader. For another example, if the outer shell 10a is substantially hexagonal, the inner annular space 110a can be substantially cylindrical, elliptical, triangular, quadrangular, pentagonal, hexagonal, heptagonal, octagonal, or enneader.

[0052] In some embodiments, the housing 10a may be provided with the aforementioned hair receiving chamber 140a, which can receive hair and dirt. The hair receiving chamber 140a may be located above at least one of the fan filter assembly 30a and the air duct assembly 80a.

[0053] For example, the hair accommodating chamber 140a can be located above the fan filter assembly 30a, which helps to reduce the space occupied by the fan filter assembly 30a above the housing 10a and helps to increase the capacity of the hair accommodating chamber 140a so that the hair accommodating chamber 140a can accommodate more hair and dirt, which helps to reduce the number of times the user needs to clean the hair.

[0054] For another example, the hair accommodating chamber 140a can be located above the air duct assembly 80a, which helps to reduce the space occupied by the air duct assembly 80a above the housing 10a, and also helps to increase the capacity of the hair accommodating chamber 140a, so that the hair accommodating chamber 140a can accommodate more hair and dirt, which helps to reduce the number of times the user needs to clean the hair.

[0055] For another example, the hair holding chamber 140a can be located above the fan filter assembly 30a and the air duct assembly 80a, which helps to reduce the space occupied by structures such as the fan filter assembly 30a and the air duct assembly 80a above the outer shell 10a, helps to increase the capacity of the hair holding chamber 140a, so that the hair holding chamber 140a can accommodate more hair and dirt, and helps to reduce the number of times the user needs to clean the hair.

[0056] In some embodiments, referring to Figures 9 and 11 , the housing 10a may include a base housing 13a and a cover housing 14a, wherein the cover housing 14a is detachably connected to the top of the base housing 13a. When the hair collection device 100a is in normal use, the base housing 13a may be placed on the ground, a table, or other locations, and the cover housing 14a is located above the base housing 13a.

[0057] In some embodiments, the cover housing 14a and the base housing 13a can be detachably connected using a snap-fit ​​structure. The cover housing 14a and the base housing 13a can also be detachably connected using fasteners such as screws or bolts. In other embodiments, the cover housing 14a and the base housing 13a can also be detachably connected using other methods.

[0058] In some embodiments, the cover housing 14a is detachably connected to the fan filter assembly 30a and the air duct assembly 80a. The cover housing 14a and the fan filter assembly 30a can be detachably connected using a snap-fit ​​structure. The cover housing 14a and the fan filter assembly 30a can also be detachably connected using fasteners such as screws and bolts. In other embodiments, the cover housing 14a and the fan filter assembly 30a can be detachably connected using other methods.

[0059] The cover housing 14a and the air duct assembly 80a can be detachably connected by a snap-fit ​​structure. The cover housing 14a and the air duct assembly 80a can also be detachably connected by fasteners such as screws and bolts. In other embodiments, the cover housing 14a and the air duct assembly 80a can also be detachably connected by other means.

[0060] In some embodiments, the cover shell 14a may have the above-mentioned hair accommodating chamber 140a. Since the cover shell 14a is detachably connected to the base shell 13a, and the cover shell 14a is detachably connected to the fan filter assembly 30a, and the cover shell 14a is detachably connected to the air duct assembly 80a, it is helpful for the user to disassemble the cover shell 14a and the base shell 13a, and remove the fan filter assembly 30a and the air duct assembly 80a from the cover shell 14a, so as to clean the hair and dirt inside the cover shell 14a.

[0061] In some embodiments, the cover housing 14a is a light-transmitting housing, which allows the user to view the hair volume in the hair receiving chamber 140a and to clean the hair receiving chamber 140a in a timely manner according to the condition of the hair receiving chamber 140a. The cover housing 14a can be a light-transmitting glass housing or a light-transmitting plastic housing.

[0062] In some embodiments, both the fan filter assembly 30a and the air duct assembly 80a may have a portion of their structure assembled to the cover housing 14a. Referring to Figures 11 to 13, the fan filter assembly 30a may include a filter element 31a, and the air duct assembly 80a may include a cavity bottom cover 81a. The filter element 31a and the cavity bottom cover 81a may be located on radially opposite sides of the inner annular wall 11a and opposite the hair receiving chamber 140a. The filter element 31a may be detachably connected to the outer annular wall 12a and the inner annular wall 11a, and the cavity bottom cover 81a may be detachably connected to the outer annular wall 12a and the inner annular wall 11a.

[0063] During the removal of the cover housing 14a from the base housing 13a, the filter 31a and the cavity bottom cover 81a help support hair dirt within the hair receiving chamber 140a, preventing the hair dirt from directly falling onto the base housing 13a. Furthermore, after the cover housing 14a and the base housing 13a are removed, the filter 31a and the cavity bottom cover 81a can be removed to clean the hair dirt within the cover housing 14a.

[0064] The bottom cover 81a of the accommodating cavity may have a through hole 810a, and the through hole 810a may be connected to the hair accommodating cavity 140a. The through hole 810a can facilitate external air to enter the hair accommodating cavity 140a.

[0065] In some embodiments, the filter element 31a can be removably connected to the outer annular wall 12a and the inner annular wall 11a using a snap-fit ​​structure. The filter element 31a can also be removably connected to the outer annular wall 12a and the inner annular wall 11a using fasteners such as screws and bolts. In other embodiments, the filter element 31a can be removably connected to the outer annular wall 12a and the inner annular wall 11a using other methods.

[0066] In some embodiments, the cavity bottom cover 81a can be removably connected to the outer annular wall 12a and the inner annular wall 11a using a snap-fit ​​structure. The cavity bottom cover 81a can also be removably connected to the outer annular wall 12a and the inner annular wall 11a using fasteners such as screws and bolts. In other embodiments, the cavity bottom cover 81a can be removably connected to the outer annular wall 12a and the inner annular wall 11a using other methods.

[0067] In some embodiments, a portion of the fan filter assembly 30a may be assembled to the base housing 13a. For example, the fan filter assembly 30a may further include a fan 32a. Since the filter element 31a is detachably connected to the cover housing 14a and the filter element 31a is opposite the hair receiving chamber 140a, the fan 32a may be located on the side of the filter element 31a facing away from the hair receiving chamber 140a, and the fan 32a may be assembled to the base housing 13a.

[0068] This embodiment arranges the fan 32a in the base housing 13a, which helps to reduce the space occupied by the fan filter assembly 30a in the hair receiving chamber 140a, so that the hair receiving chamber 140a can accommodate more hair and dirt. It also helps to reduce the weight of the cover housing 14a and lower the center of gravity of the hair collection device 100a, thereby helping to reduce the possibility of the hair collection device 100a tipping over due to an excessively high center of gravity.

[0069] In some embodiments, the fan 32a can be assembled to the base housing 13a in a variety of ways. For example, the fan 32a can be fixed to the base housing 13a by fasteners such as screws and bolts.

[0070] In some embodiments, a portion of the air duct assembly 80a may be assembled to the base housing 13a. For example, the air duct assembly 80a may further include an air inlet duct 82a. Since the cavity bottom cover 81a is detachably connected to the cover housing 14a, and the cavity bottom cover 81a is opposite the hair receiving cavity 140a, the air inlet duct 82a may be located on a side of the cavity bottom cover 81a facing away from the hair receiving cavity 140a and connected to the through hole 810a. The air inlet duct 82a may be assembled to the base housing 13a.

[0071] This embodiment arranges the air inlet duct 82a in the base housing 13a, which helps to reduce the space occupied by the air duct assembly 80a in the hair accommodating chamber 140a, so that the hair accommodating chamber 140a can accommodate more hair and dirt. It also helps to reduce the weight of the cover housing 14a and lower the center of gravity of the hair collecting device 100a, thereby helping to reduce the situation where the hair collecting device 100a tips over due to an excessively high center of gravity.

[0072] In some embodiments, the air inlet duct 82a can be assembled to the base housing 13a in a variety of ways. For example, the air inlet duct 82a can be fixed to the base housing 13a by fasteners such as screws and bolts.

[0073] In some embodiments, referring to Figures 9 and 13 , the hair collection device 100a may further include a connecting duct 70a, which may be connected to the air duct assembly 80a and located within the base housing 13a. An air inlet 71a of the hair collection device 100a may be located within the connecting duct 70a. The connecting duct 70a may be connected to a handle via a flexible hose, allowing a user to hold the handle to suction hair and dirt.

[0074] In addition, the connecting pipe 70a assembled on the base shell 13a helps to avoid occupying the spatial position of the cover shell 14a, helps to increase the capacity of the hair accommodating chamber 140a of the cover shell 14a, so that the hair accommodating chamber 140a can accommodate more hair dirt, and helps to reduce the number of times the user needs to clean the hair.

[0075] The connecting pipe 70a assembled on the base housing 13a also helps to reduce the weight of the cover housing 14a, helps to lower the center of gravity of the hair collecting device 100a, and further helps to reduce the situation where the hair collecting device 100a falls over due to an excessively high center of gravity.

[0076] In some embodiments, the connecting pipe 70a can be protruded outside the shell 10a along the thickness direction of the shell 10a, so that the connecting pipe 70a and the hose connected to the connecting pipe 70a can provide a certain supporting force to the shell 10a from the thickness direction, which helps to reduce the possibility of the hair collection device 100a tipping over.

[0077] In some embodiments, referring to Figures 8 and 9, the housing 10a has an air outlet 15a, which can be located on the side of the base shell 13a away from the connecting pipe 70a. This avoids the air outlet 15a and the connecting pipe 70a being located on the same side, which causes the connecting pipe 70a to occupy too much position and limit the size of the air outlet 15a. It also avoids the connecting pipe 70a blocking the air outlet 15a, which helps the air outlet 15a to discharge air smoothly.

[0078] In some embodiments, referring to FIG. 11 , the hair collection device 100a may further include a control panel 90a. The control panel 90a may be mounted within the base housing 13a and positioned below the inner annular wall 11a. The control panel 90a is electrically connected to the fan 32a. This arrangement helps reduce the space occupied by the control panel 90a within the hair-receiving chamber 140a, allowing the chamber 140a to accommodate more hair. It also helps reduce the weight of the cover housing 14a, lowering the center of gravity of the hair collection device 100a and thereby reducing the risk of the hair collection device 100a tipping over due to an excessively high center of gravity.

[0079] In some embodiments, the control board 90a may be a rigid circuit board, a flexible circuit board, or a rigid-flexible circuit board.

[0080] In some embodiments, referring to Figures 8 and 14, the hair collection device 100a may further include a functional device 20a, which may be assembled on the base housing 13a. The functional device 20a may be exposed to the outer shell 10a from the inner ring wall 11a, and the functional device 20a is electrically connected to the control board 90a. The inner ring wall 11a of the outer shell 10a provides certain protection for the functional device 20a, thereby reducing the impact of external hard objects on the functional device 20a, helping to improve the space utilization of the hair collection device 100a at the inner ring space 110a, helping to prevent the functional device 20a from being hit from top to bottom by hard objects when it is located at the top of the outer shell 10a, helping to prevent the functional device 20a from being hit from bottom to top by hard objects when it is located at the bottom of the outer shell 10a, and helping to prevent the functional device 20a from being hit from top to bottom, left to right, and right to left by hard objects when it is located on the side wall of the outer shell 10a.

[0081] Since the base housing 13a is located below the cover housing 14a, it is convenient for the user to operate and view the functional device 20a, for example, it is convenient for the user to operate and view the functional device 20a from top to bottom.

[0082] Furthermore, the functional device 20a assembled in the base housing 13a helps avoid occupying the space of the cover housing 14a, thereby increasing the capacity of the hair-receiving chamber 140a of the cover housing 14a. This allows the hair-receiving chamber 140a to accommodate a larger amount of dirty hair, thus reducing the number of times the user needs to clean the hair. The base housing 13a may be provided with the aforementioned inner ring through-hole. The functional device 20a assembled in the base housing 13a also helps reduce the weight of the cover housing 14a, thereby lowering the center of gravity of the hair collection device 100a, thereby reducing the risk of the hair collection device 100a tipping over due to an excessively high center of gravity.

[0083] In addition, during the process of assembling the functional device 20a and the outer shell 10a, since the cover shell 14a is detachably connected to the base shell 13a, it is convenient for the functional device 20a to be assembled on the base shell 13a, and then the cover shell 14a is connected to the base shell 13a, thereby avoiding the functional device 20a being blocked by the cover shell 14a during the process of being assembled on the base shell 13a, which helps to simplify the difficulty of assembling the functional device 20a on the outer shell 10a and exposing it to the inner ring space 110a.

[0084] In some embodiments, the inner annular space 110a can pass through the outer shell 10a along the axial direction of the inner annular wall 11a. This helps the user to operate and view the functional device 20a on both sides of the axial direction of the inner annular wall 11a, thereby improving the convenience of the user in operating and viewing the functional device 20a.

[0085] In some embodiments, the inner diameter of the inner annular wall 11a may increase in a direction away from the center of the inner annular wall 11a, which helps reduce the obstruction of the user's field of vision caused by the inner annular wall 11a and facilitates observation of the functional device 20a.

[0086] In some embodiments, the inner ring wall 11a may be provided with an inner ring through hole, which is connected to the inner ring space 110a, so that the functional device 20a is exposed to the inner ring space 110a through the inner ring through hole.

[0087] In some embodiments, the functional device 20a may be partially exposed from the outer shell 10a to the inner annular space 110a, or the functional device 20a may be entirely exposed from the inner annular space 110a.

[0088] In some embodiments, the functional device 20a may be assembled to the housing 10a in various ways depending on the actual situation. For example, the functional device 20a may be snap-fitted to the housing 10a; another example is the functional device 20a being fixed to the housing 10a using fasteners such as screws or bolts; another example is the functional device 20a being bonded to the housing 10a by gluing.

[0089] In some embodiments, the functional device 20a may include at least one of a touch switch, a button, a knob, a touch screen, a display screen, and a lamp. The touch switch is a touch-sensitive element that can sense a user's touch operation. The buttons and knobs are mechanical components that allow the user to control corresponding functions of the hair collection device 100a by pressing a button or turning a knob. The display screen can display text, images, or images. The display screen can be a touch screen or a non-touch screen. The lamp can be an indicator light, a lighting lamp, a signal light, or other types.

[0090] In some embodiments, when the functional device 20a includes a button, the button exposed within the inner annular space 110a can also facilitate user pressing. For example, the user can insert a finger of one hand into the inner annular space 110a to press the button. Because the buttons of the hair collection device 100a of the related art are located on the side wall of the housing 10a, excessive force applied when the user presses the button may cause the entire device to shake or move backward, or require the user to hold the entire device with one hand while pressing with the other hand, which is inconvenient.

[0091] In some embodiments, when the cover shell 14a is a light-transmitting shell and the functional device 20a includes a lamp body 23a, the light emitted by the lamp body 23a helps to pass through the cover shell 14a more easily into the user's field of vision, making it easier for the user to know the status of the lamp body 23a.

[0092] In some embodiments, referring to FIG. 14 , the functional device 20 a may include a first switch 21 a , a second switch 22 a , and a lamp body 23 a , and the first switch 21 a , the second switch 22 a , and the lamp body 23 a are all exposed outside the inner annular space 110 a .

[0093] In some embodiments, the first switch 21a and the second switch 22a may be the same type of switch or different types of switches. For example, the first switch 21a may be a touch switch, a button, a knob, or other types. The second switch 22a may be a touch switch, a button, a knob, or other types.

[0094] In some embodiments, the first switch 21a and the second switch 22a can control different functions of the hair collecting device 100a, for example, they can control the power on, power off, pause, standby, gear position, function mode, etc. of the hair collecting device 100a.

[0095] In some embodiments, the first switch 21a can control a function of the hair collecting device 100a. For example, the first switch 21a can be a power switch, and the first switch 21a can control the hair collecting device 100a to start.

[0096] In some embodiments, the second switch 22a can control a function of the hair collecting device 100a. For example, the second switch 22a can be an off switch, and the second switch 22a can control the hair collecting device 100a to be turned off.

[0097] In some embodiments, the first switch 21a can control multiple functions of the hair collecting device 100a. For example, the first switch 21a can be a power on / off switch, and the first switch 21a can control the hair collecting device 100a to start and stop.

[0098] In some embodiments, the second switch 22a can control multiple functions of the hair collection device 100a. For example, the second switch 22a can be a gear switch, and the second switch 22a can control the hair collection device 100a to be in different gears, such as low gear, medium gear, high gear, etc.

[0099] In some embodiments, the lamp body 23a can be located between the first switch 21a and the second switch 22a, helping to separate the first switch 21a and the second switch 22a. This prevents the first switch 21a and the second switch 22a from being too close together, which could cause the user to accidentally trigger the second switch 22a when operating the first switch 21a. This also helps prevent the user from accidentally triggering the first switch 21a when operating the second switch 22a, effectively reducing the possibility of false triggering. In addition, in dimly lit environments, the light emitted by the lamp body 23a allows the user to more clearly see the first switch 21a and the second switch 22a.

[0100] In some embodiments, the first switch 21a may be provided with a first mark 211a, and the second switch 22a may be provided with a second mark 221a. The second mark 221a is distinguishable from the first mark 211a, so that the user can easily identify the position of the switch and the corresponding function of the switch.

[0101] In some embodiments, the first mark 211a may be disposed close to the lamp body 23a, so that the user can more clearly see the first mark 211a with the help of the light emitted by the lamp body 23a, so that the user can recognize the function of the first switch 21a.

[0102] In some embodiments, the second mark 221a can be disposed close to the lamp body 23a, so that the user can more clearly see the second mark 221a with the help of the light emitted by the lamp body 23a, so that the user can identify the function of the first switch 21a.

[0103] In the hair collection device 100a provided in this embodiment, the housing 10a of the hair collection device 100a has an inner annular wall 11a, and the fan filter assembly 30a and the air duct assembly 80a are both assembled in the housing 10a. The fan filter assembly 30a and the air duct assembly 80a are respectively located on the radial sides of the inner annular wall 11a. This helps to use the inner annular wall 11a of the housing 10a to separate the fan filter assembly 30a and the air duct assembly 80a, so that the distance between the fan filter assembly 30a and the air duct assembly 80a will not be too close, thereby helping to avoid the situation where the two are too close and hair near the fan filter assembly 30a falls into the air duct assembly 80a, and helps to balance the weight of the hair collection device 100a along the radial sides of the inner annular wall 11a.

[0104] Referring to Figures 15-17, another embodiment of the present application provides a hair collection device 100b. The hair collection device 100b includes a housing 10b, a fan assembly 30b, and a filter assembly 40b. The fan assembly 30b and the filter assembly 40b are both assembled within the housing 10b. The hair collection device 100b also has an air inlet 71b, a hair receiving chamber 140b, and an air outlet 15b located on the housing 10b. The housing 10b is annular and has an inner annular wall 11b and an outer annular wall 12b. The fan assembly 30b can be located between the inner annular wall 11b and the outer annular wall 12b, and the filter assembly 40b can be located between the inner annular wall 11b and the outer annular wall 12b. The inner annular wall 11b and the outer annular wall 12b of the housing 10b provide a certain degree of protection for the fan assembly 30b and the filter assembly 40b.

[0105] In some embodiments, the hair-receiving chamber 140b is located between the inner annular wall 11b and the outer annular wall 12b. The air inlet 71b is located on the outer annular wall 12b or elsewhere on the hair-collecting device 100b, and the air outlet 15b is located on the outer annular wall 12b or elsewhere on the hair-collecting device 100b. The filter assembly 40b and the fan assembly 30b are both located below the hair-receiving chamber 140b.

[0106] In some embodiments, the inner annular wall 11b encloses an inner annular space 110b. The hair collection device 100b further includes a functional component 20b, which is mounted on the outer shell 10b and exposed in the inner annular space 110b. The inner annular space 110b extends through the outer shell 10b along the axial direction of the inner annular wall 11b, allowing a user to operate and view the functional component 20b from both sides of the axial direction of the inner annular wall 11b.

[0107] In some embodiments, the inner diameter of the inner annular wall 11b increases in a direction away from the center of the inner annular wall 11b, thereby reducing the obstruction of the inner annular wall 11b to the user's field of vision and facilitating viewing of the functional device 20b.

[0108] In some embodiments, the functional device 20b may be partially exposed from the outer shell 10b to the inner annular space 110b, or the functional device 20b may be entirely exposed from the inner annular space 110b.

[0109] In some embodiments, referring to Figures 15-16, the hair collection device 100b may further include a power cord 50b, which can be connected to a power source. The power cord 50b can be connected to the outer ring wall 12b, thereby effectively utilizing the outer ring wall 12b of the housing 10b and facilitating installation of the power cord 50b within the housing 10b.

[0110] In addition, since the power cord 50b is connected to the outer ring wall 12b instead of the axial end surface of the housing 10b, it helps to reduce the hair collection device 100b from tipping over along the axial direction of the housing 10b when the user pulls the power cord 50b.

[0111] When the hair collection device 100b is not in use, the inner annular space 110b formed by the inner annular wall 11b also facilitates storage of the power cord 50b. For example, the power cord 50b can be bent and inserted into the inner annular space 110b. Alternatively, the power cord 50b can be wrapped around the outer shell 10b and passed through the inner annular space 110b, thereby improving the utilization of the inner annular space 110b.

[0112] In some embodiments, the inner diameter of the inner annular wall 11b may be greater than or equal to twice the outer diameter of the power cord 50b and less than or equal to 10 times the outer diameter of the power cord 50b. For example, the inner diameter of the inner annular wall 11b may be greater than or equal to 2, 2.5, 3, 3.5, 4, 4.5, 5, 5.5, 6, 6.5, 7, 7.5, 8, 8.5, 9, 9.5, or 10 times the outer diameter of the power cord 50b. In this way, the inner diameter of the inner annular wall 11b is neither too small, making it difficult to accommodate the power cord 50b within the inner annular space 110b, nor too large, causing the inner annular space 110b to be too large and resulting in insufficient space within the housing 10b, which in turn limits the placement of components within the housing 10b.

[0113] Among them, when the inner diameter of the inner ring wall 11b changes, for example, when the inner diameter of the inner ring wall 11b increases in the direction away from the center of the inner ring wall 11b, then the inner diameter of the inner ring wall 11b is greater than or equal to 2 times the outer diameter of the power cord 50b and less than or equal to 10 times the outer diameter of the power cord 50b, which means that the minimum inner diameter of the inner ring wall 11b is greater than or equal to 2 times the outer diameter of the power cord 50b and less than or equal to 10 times the outer diameter of the power cord 50b.

[0114] In some embodiments, referring to Figures 16-17, the housing 10b may include a base housing 13b and a cover housing 14b, wherein the cover housing 14b is detachably connected to the top of the base housing 13b. When the hair collection device 100b is in normal use, the base housing 13b may be placed on the ground, a table, or other locations, and the cover housing 14b is located above the base housing 13b.

[0115] In some embodiments, the cover housing 14b and the base housing 13b can be detachably connected by snapping. The cover housing 14b and the base housing 13b can also be detachably connected by fasteners such as screws or bolts. In other embodiments, the cover housing 14b and the base housing 13b can also be detachably connected by other means.

[0116] In some embodiments, the cover housing 14b may have the aforementioned hair receiving chamber 140b therein, which can accommodate hair dirt. Since the cover housing 14b is detachably connected to the base housing 13b, it is helpful for the user to clean the hair dirt in the cover housing 14 by disassembling the cover housing 14b from the base housing 13b.

[0117] In some embodiments, the cover housing 14b and the base housing 13b can together enclose an inner annular space 110b, and the functional device 20b can be assembled in the base housing 13b. In this way, since the base housing 13b is located below the cover housing 14b, it is convenient for the user to operate and view the functional device 20b, for example, facilitating the user to operate and view the functional device 20b from top to bottom.

[0118] Furthermore, the functional device 20b assembled in the base housing 13b helps avoid occupying the space of the cover housing 14b, thereby increasing the capacity of the hair receiving chamber 140b of the cover housing 14b, so that the hair receiving chamber 140b can accommodate more hair and dirt, thereby reducing the number of times the user needs to clean the hair. The base housing 13b may be provided with the aforementioned inner ring through-hole.

[0119] The functional device 20b assembled on the base housing 13b also helps to reduce the weight of the cover housing 14b, helps to lower the center of gravity of the hair collecting device 100b, and further helps to reduce the situation where the hair collecting device 100b falls over due to an excessively high center of gravity.

[0120] In addition, during the process of assembling the functional device 20b and the outer shell 10b, since the cover shell 14b is detachably connected to the base shell 13b, the functional device 20b can be assembled on the base shell 13b, and then the cover shell 14b is connected to the base shell 13b, thereby avoiding the functional device 20b being blocked by the cover shell 14b during the process of being assembled on the base shell 13b, which helps to simplify the difficulty of assembling the functional device 20b on the outer shell 10b and exposing it to the inner ring space 110b.

[0121] In some embodiments, the cover shell 14b is a light-transmitting shell, which helps the user to check the hair capacity in the hair receiving chamber 140b, so that the user can clean the hair receiving chamber 140b in a timely manner according to the actual situation in the hair receiving chamber 140b.

[0122] In some embodiments, the fan assembly 30b of the hair collection device 100b can be assembled in the base housing 13b, which helps to reduce the space occupied by the fan assembly 30b in the hair accommodating chamber 140b, so that the hair accommodating chamber 140b can accommodate more hair and dirt. It also helps to reduce the weight of the cover housing 14b, lower the center of gravity of the hair collection device 100b, and reduce the risk of the hair collection device 100b tipping over due to an excessively high center of gravity.

[0123] In some embodiments, the filter assembly 40b of the hair collecting device 100b may be assembled in the cover housing 14b, and the filter assembly 40b and the fan assembly 30b may be opposite to each other.

[0124] In some embodiments, the hair collection device 100b further includes a handle 60b, which can be connected to the housing 10b. For example, the handle 60b can be connected to the housing 10b by snapping, or fixedly connected to the housing 10b by screws, bolts, or other fasteners, or glued. The handle 60b can be connected to the cover housing 14b of the housing 10b.
