[0046] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0047] To facilitate quick disassembly of the filter mechanism by users, the applicant has developed a filtration system for cleaning equipment, wherein the cleaning equipment can be a vacuum cleaner or other device used to adsorb and collect dust from the surface to be cleaned. In this filtration system, the filter mechanism can be quickly disassembled and assembled, making it convenient for users to replace and maintain the filter mechanism.

[0048] Specifically, please refer to Figure 1 and Figure 2 , Figure 1 This is a cross-sectional structural schematic diagram of one embodiment of the filtration system of the cleaning equipment of this application. Figure 2 This is an exploded structural diagram of one embodiment of the filtration system of the cleaning equipment of this application.

[0049] like Figure 1 and Figure 2 As shown, the filtration system includes a main body 100, inside which an air duct 101 extending along a first direction x is formed. One end of the main body 100 is provided with an opening 102 communicating with the air duct 101, and the other end is provided with an air inlet 107. A filter part 200 is arranged inside the air duct 101, and a cover 300 is detachably provided at the opening 102.

[0050] The filter unit 200 is used to filter the air blown out through the air duct 101, thereby achieving air filtration and trapping dust and other particles inside the cleaning equipment.

[0051] After the cover 300 is removed, the filter part 200 can be inserted or pulled out along the extension direction of the air duct 101, thereby realizing the quick disassembly and assembly of the filter part 200, which is convenient for users to replace and maintain the filter part 200.

[0052] Specifically, in this embodiment, the filter unit 200 includes a first cylindrical bracket 201 extending along the first direction x, and a first filter assembly 202 sleeved and installed on the first cylindrical bracket 201. The first filter assembly 202 can be disassembled or installed by pulling the first cylindrical bracket 201 out of the air duct 101 or inserting it into the air duct 101.

[0053] During vacuuming, airflow enters through the air inlet, is filtered by the filtration system, and then flows out. The cover is the rear cover.

[0054] In this embodiment, the first filter component 202 is a filter cotton used for primary filtration. In other embodiments, the first filter component 202 can also be other materials that can filter air, such as a HEPA filter 2052, etc., all of which can achieve the effect of this embodiment.

[0055] The main body 100 includes a motor cover 103, a body cover 104 fitted over the motor cover 103, and an outermost housing 105. An air duct 101 is formed between the motor cover 103 and the body cover 104. In a specific implementation, the internal space of the motor cover 103 can be used to install a motor, which drives the airflow through the air duct 101. The airflow is filtered when it passes through the first filter assembly 202 and is finally discharged from the machine body through the exhaust port on the housing 105.

[0056] In this embodiment, the cover 300 can be fixed to the opening 102 in any way, such as by snap-fit, interference fit, bolt, spring snap, magnetic attraction, fastener, etc., as long as the cover 300 can be detached, the effect of this embodiment can be achieved.

[0057] To facilitate the user's removal of the first cylindrical bracket 201 from the air duct 101, please refer to [link / reference]. Figure 3 , Figure 3 This is a structural schematic diagram of one embodiment of the first cylindrical support of this application. Figure 3 As shown, a handle 203 is also provided at one end of the first cylindrical bracket 201 near the cover 300. After disassembling the cover 300, the user can pull the first cylindrical bracket 201 and the first filter assembly 202 out of the air duct 101 from the opening 102 by pulling the handle 203, thereby realizing the quick disassembly of the filter part 200.

[0058] Specifically, in this embodiment, the handle 203 is rotatably mounted on the end face of the first cylindrical bracket 201. When the first cylindrical bracket 201 is installed in place, the handle 203 can be rotated to fit against the end face of the first cylindrical bracket 201. At this time, the handle 203 is in a closed position and does not affect the closing of the cover 300.

[0059] When it is necessary to disassemble or assemble the filter section 200, the handle 203 can be rotated to form an angle with the end face of the first cylindrical bracket 201. At this time, the handle 203 is in an open position, providing the user with space to reach out and hold the handle 203, making it convenient for the user to disassemble or assemble.

[0060] In this embodiment, the handle 203 is an arc-shaped structure that matches the end face of the first cylindrical support 201 in an annular shape, so that the orthographic projection of the handle 203 and the end face of the first cylindrical support 201 in the first direction x can completely overlap, thus avoiding the handle 203 protruding from the first cylindrical support 201 in the radial direction of the air duct 101 and optimizing the internal space design.

[0061] Furthermore, in this embodiment, the end face of the first cylindrical bracket 201 is provided with an installation groove 2011 that matches the handle 203. When in the closed position, the handle 203 can be completely embedded in the installation groove 2011, so that the end face of the handle 203 can be flush with the first cylindrical bracket 201, further optimizing the utilization of internal space and avoiding affecting the closing of the cover 300.

[0062] Specifically, in this embodiment, a pivot 2031 is arranged at the end of the handle 203, and an insertion hole 2012 matching the pivot 2031 is arranged on the end face of the first cylindrical bracket 201. The pivot 2031 is inserted into the insertion hole 2012, and the handle 203 can rotate around the pivot 2031.

[0063] Of course, in other embodiments, the structure of the handle 203 can also be designed based on actual needs. For example, the shape of the handle 203 may not match the end face of the first cylindrical bracket 201, or the handle 203 may be fixedly set. For example, the handle 203 may be a beam structure extending radially along the first cylindrical bracket 201, or the handle 203 may be a spring cover structure, which the user can press to make the handle 203 pop out, etc. As long as it is convenient for the user to hold and pull out the first cylindrical bracket 201, the effect of this embodiment can be achieved.

[0064] Please continue reading. Figure 1 In this embodiment, the first cylindrical support 201 extends from the inner end of the air duct 101 along the extension direction of the air duct 101 to the end of the air duct 101 near the opening 102. On the one hand, the cover 300 covering the opening 102 can press the first cylindrical support 201 to limit the filter part 200 in the air duct 101. On the other hand, it can also facilitate the user to quickly disassemble the first cylindrical support 201.

[0065] Of course, in other embodiments, the extension length of the first cylindrical bracket 201 can be adjusted according to actual needs. The first cylindrical bracket 201 may not extend to the opening 102 end of the air duct 101. The first cylindrical bracket 201 may also adopt other fixing methods, all of which can achieve the effect of quick assembly and disassembly of this application.

[0066] The structure of the first cylindrical support 201 in this embodiment is described in detail below. Please refer to [link / reference]. Figures 4 to 6 , Figure 4 This is an exploded structural diagram of one embodiment of the filtering section of this application. Figure 5 This is a cross-sectional structural diagram of one embodiment of the assembly structure of the filter section and the housing in this application. Figure 6 yes Figure 5 A magnified view of part A in the diagram.

[0067] like Figure 4 As shown, the first cylindrical support 201 includes a first extension section 2013 and a second extension section 2014 arranged sequentially along the first direction x. The first filter assembly 202 is sleeved on the first extension section 2013, and the second extension section 2014 extends to the air duct 101 near the air outlet to facilitate the fixing and disassembly of the filter part 200.

[0068] Furthermore, the end of the first filter assembly 202 away from the second extension 2014 is provided with a plurality of annularly arranged slots 2021. The filter part 200 also includes a sensing element 204 arranged in the slots 2021. The filter part 200 also includes a sealing ring 206 sleeved on the end of the first filter assembly 202. The sealing ring 206 covers the slots 2021 and wraps the sensing element 204, thereby fixing the sensing element 204.

[0069] like Figure 5 and Figure 6 As shown, a leak-proof sensor (not shown) for detecting the sensing element 204 is arranged on the housing 105 of the main unit. When the first cylindrical bracket 201 is installed in place, one of the multiple sensing elements 204 can be aligned with the position of the leak-proof sensor to trigger the leak-proof sensor, thereby realizing the reminder of the first filter component 202 being missing.

[0070] In this embodiment, the anti-leakage sensor is a Hall sensor built into the display screen 106, and a Hall sensing point 1061 is formed on the back of the display screen 106. The sensing element 204 is a magnet. When the magnet is directly opposite the Hall sensing point 1061, the magnetic field lines of the magnet can act on the Hall sensing point 1061, so that the Hall sensor detects the magnet and obtains a signal that the filter unit 200 has been installed. The Hall sensor can be connected to the display screen 106, so that the display screen 106 can display the signal that "the filter unit has been installed".

[0071] Conversely, when the magnetic field lines of the magnet do not act on the Hall sensor, a signal indicating that the filter unit 200 is not installed can be obtained, which can then cause the display screen 106 to display a signal indicating that the filter unit is missing, thus reminding the user that the filter unit is missing.

[0072] In other embodiments, the sensing element 204 may not be a magnet, and the anti-leakage sensor may not be a Hall sensor. For example, the sensing element 204 may be a conductor, the anti-leakage sensor may be an inductive position sensor, and so on. Devices that can achieve similar functions can achieve the effects of this embodiment.

[0073] In this embodiment, the sensor 204 is disposed at the end of the first filter assembly 202. In other embodiments, the installation position of the sensor 204 can be adjusted according to actual needs and fixed in other ways. For example, the sensor 204 can also be disposed in the middle of the first filter assembly 202, etc., all of which can achieve the effect of this embodiment.

[0074] In this embodiment, the anti-missed-item sensor is a Hall sensor built into the display screen 106. In other embodiments, the display screen 106 can be omitted. For example, the signal of the Hall sensor can be sent to the user's app to remind them of the missing item. Alternatively, the Hall sensor and the display screen 106 can be designed separately, which can also achieve the effect of this embodiment.

[0075] In this embodiment, the end of the first filter assembly 202 is provided with six magnets arranged at uniform intervals in a ring. To ensure that when the first cylindrical support is installed in place, one of the six magnets is positioned directly opposite the Hall sensing point 1061, this embodiment also includes a guide mechanism for limiting the assembly angle of the first cylindrical support. Please refer to [link to relevant documentation]. Figure 7 , Figure 7 This is a schematic diagram of one embodiment of the assembly structure of the first cylindrical support and motor cover in this application.

[0076] Optionally, the main body includes a motor cover and a body cover fitted over the motor cover, wherein the motor cover and / or the body cover are provided with guide grooves that match the first cylindrical support; wherein the first cylindrical support includes pillars arranged at intervals along the circumference of the air duct, the pillars extending along the extension direction of the air duct, and the motor cover is provided with guide grooves corresponding to the pillars.

[0077] There can be multiple guide slots, and there can also be multiple support pillars, with each support pillar and guide slot corresponding to the other. For example... Figure 7As shown, the second extension 2014 of the first cylindrical support includes six pillars 20141 evenly spaced along the circumference of the air duct 101. Each pillar 20141 extends along the first direction x. The motor cover 103 is provided with guide grooves 1031 corresponding to the six pillars 20141, so that the first cylindrical support can be installed into the air duct 101 at six different assembly angles. At each assembly angle, one of the six magnets can be directly aligned with the Hall sensing point 1061, ensuring effective sensing of the first filter component 202, thereby improving the accuracy and flexibility of the assembly.

[0078] In other embodiments, the guide groove 1031 can also be provided on the body cover 104, or other guiding mechanisms can be used, as long as the assembly angle of the first cylinder support is limited, all of which can achieve the effect of this embodiment.

[0079] It should be understood that the reason for using six circumferentially distributed magnets in this embodiment is that the first cylindrical support has six assembly angles. In other embodiments, the number and distribution of magnets can be adjusted based on actual needs. For example, when the pillars 20141 of the first cylindrical support are irregularly arranged, the first cylindrical support may have only one assembly angle. In this case, only one magnet may be arranged on the first filter assembly 202. Alternatively, when the first cylindrical support includes four evenly spaced pillars 20141, the first cylindrical support may have four assembly angles. In this case, four magnets may be arranged on the first filter assembly 202. Or, the first cylindrical support may include two symmetrically arranged sets of pillars 20141, and the first cylindrical support may have two assembly angles. In this case, two magnets may be arranged on the first filter assembly 202. Alternatively, the assembly angle of the first cylindrical support may not be limited, and annular magnets may be arranged on the first filter assembly 202. All of these can achieve the effects of this embodiment and should fall within the protection scope of this application.

[0080] In the above embodiments, the filter unit 200 only includes the first filter component 202. To further optimize the filtration effect, in another embodiment, the filter unit 200 may also include other filter materials. Please refer to [link to relevant documentation]. Figure 8 , Figure 8 This is a cross-sectional structural schematic diagram of another embodiment of the filtration system of the cleaning equipment of this application.

[0081] like Figure 8 As shown, in this embodiment, the filter section 200 further includes a second filter assembly 205, which can be sleeved on the second extension section 2014 of the first cylindrical bracket 201.

[0082] Specifically, in this embodiment, the second filter component 205 includes HEPA filter material. In other embodiments, the second filter component 205 may also use other materials that can filter air, such as filter cotton, filter membrane, electrostatic fiber, etc.

[0083] To facilitate the quick assembly and disassembly of the second filter assembly 205, in this embodiment the second filter assembly 205 and the cover 300 are detachably connected, so that the assembly and disassembly of the second filter assembly 205 can be carried out simultaneously when the cover 300 is assembled and disassembled.

[0084] The connection structure between the second filter component 205 and the cover 300 in this embodiment is described in detail below. Please refer to [link / reference]. Figure 9 , Figure 9 This is an exploded structural diagram of an embodiment of the second filter component and cover of this application.

[0085] like Figure 9 As shown, a snap-fit ​​structure 2054 is arranged at one end of the second filter assembly 205 near the cover 300, and a matching snap-fit ​​structure 302 is arranged on the cover 300 to match the snap-fit ​​structure 2054. The snap-fit ​​structure 2054 and the matching snap-fit ​​structure 302 cooperate to limit the cover 300 and the second filter assembly 205 in the extension direction of the air duct 101.

[0086] Specifically, the second filter assembly 205 includes a second cylindrical support 2051, a HEPA filter 2052 sleeved on the second cylindrical support 2051, and a pressure ring 2053 arranged at the end of the second cylindrical support 2051. The pressure ring 2053 and the second cylindrical support 2051 can cooperate to fix the HEPA filter 2052.

[0087] In this embodiment, the snap-fit ​​structure 2054 is arranged on the outer ring surface of the pressure ring 2053, and the snap-fit ​​structure 2054 includes a plurality of snap fasteners 20541 arranged in a ring.

[0088] The cover 300 includes an adapter cover 301 arranged on the side facing the second filter assembly 205, and a mating snap-fit ​​structure 302 arranged on the annular surface of the adapter cover 301. The mating snap-fit ​​structure 302 includes a plurality of snaps 3021 corresponding one-to-one with a plurality of snaps 20541.

[0089] Please see Figure 10 , Figure 10 This is a schematic diagram of the assembly structure of an embodiment of the second filtering component of this application. Figure 10As shown, the latch 3021 includes a first latch segment 30211 and a second latch segment 30212 arranged sequentially along the circumference of the adapter cover 301. The first latch segment 30211 extends in the direction pointing towards the second filter assembly 205 to one end of the adapter cover 301 near the second filter assembly 205. One end of the second latch segment 30212 is connected to the first latch segment 30211, and the other end extends along the circumference of the adapter cover 301. The buckle 20541 can be rotated and inserted into the second latch segment 30212 via the first latch segment 30211, thereby realizing the detachable connection between the second filter assembly 205 and the cover 300.

[0090] In this embodiment, a protrusion 20542 is arranged on the side wall of the buckle 20541, and a groove 30213 matching the protrusion 20542 is arranged on the side wall of the second bayonet segment 30212, thereby ensuring the connection stability of the cover 300 and the second filter assembly 205. In other embodiments, the shapes of the buckle 20541 and the bayonet 3021 can also be designed based on actual needs, and the effects of this embodiment can be achieved.

[0091] It should be noted that in this embodiment, the snap-fit ​​structure 2054 includes multiple snap fasteners 20541, and the mating snap-fit ​​structure 302 includes multiple latches 3021 that correspond one-to-one with the multiple snap fasteners 20541. In other embodiments, the snap-fit ​​structure 2054 may also include only one snap fastener 20541, and correspondingly, the mating snap-fit ​​structure 302 may also include only one set of multiple latches 3021 that match the snap fastener 20541, which can also achieve the effect of this embodiment. It can be adjusted according to actual needs.

[0092] Understandably, the connection structure of the cover 300 and the second filter assembly 205 facilitates quick separation of the cover 300 and the second filter assembly 205, which helps users replace and maintain the second filter assembly 205. Of course, in other embodiments, the cover 300 and the second filter assembly 205 can also be detachably connected in other ways, such as through snap-fit ​​structures, spring-loaded structures, magnetic attraction, bolt structures, pin structures, fastener connections, etc., which can also achieve the effect of simultaneously assembling and disassembling the second filter assembly 205 when assembling and disassembling the cover 300 in this embodiment.

[0093] The above embodiments only show examples where the filter section 200 includes only the first filter component 202 and the filter section 200 includes both the first filter component 202 and the second filter component 205. In other embodiments, the filter section 200 may also include only the second filter component 205 which is detachably connected to the cover 300, which can also achieve the effect of quick assembly and disassembly of the filter section 200.

[0094] Based on the filtration system of the cleaning equipment described above, users can quickly disassemble and install the filter components, making it convenient for users to maintain and replace the filter components. At the same time, it can also provide reminders of missing filter components, which helps to improve the user experience.

[0095] This application also provides a cleaning device that includes the filtration system of any of the above embodiments.
