Detailed Implementation

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0018] Please refer to Figures 1-6 A cleaning mechanism 3 for an air purifier. The air purifier includes a housing 1 and a pre-filter 2. One side of the housing 1 has a sliding groove 11. The pre-filter 2 is installed in the sliding groove 11. The cleaning mechanism 3 can press against or separate from the pre-filter 2. The cleaning mechanism 3 is slidably connected to the housing 1 so that the cleaning mechanism 3 can slide relative to the air inlet side of the pre-filter 2.

[0019] Understandably, by setting a cleaning mechanism 3 on the surface of the pre-filter 2 to remove dust from the surface of the pre-filter 2, there is no need to disassemble the pre-filter 2, making the operation simpler compared to existing technologies.

[0020] In some embodiments, the cleaning mechanism 3 includes a locking component 31 and a cleaning component 32; a locking component 31 is respectively provided at both ends of the cleaning component 32 along its length; the locking component 31 is slidably connected to the housing 1, and the locking component 31 is used to make the cleaning component 32 press against or separate from the pre-filter 2. The locking mechanism controls the pressing relationship between the cleaning component 32 and the surface of the pre-filter 2, so that when dust removal of the pre-filter 2 is required, the cleaning component 32 presses against the surface of the pre-filter 2 and moves the cleaning component 32 along the surface of the pre-filter 2, so that the debris is scraped off from the surface of the pre-filter 2. The locking component 31 can also be used to lock the position of the cleaning component 32 when the pre-filter surface does not need to be cleaned, ensuring the stability of the cleaning component 32.

[0021] In some embodiments, the cleaning component 32 includes a limiting member 321, a scraper 322, a fixing member 323, and a connecting component 324. The scraper 322 is movably connected to the fixing member 323 via the connecting component 324, so that the distance between the scraper 322 and the fixing member 323 can be changed. One end of the limiting member 321 is connected to the scraper 322, and the other end of the limiting member 321 passes through the fixing member 323 and is connected to the locking component 31. By cooperating with the limiting member 321 and the locking component 31, the relative positional relationship between the scraper 322 and the pre-filter component can be changed, reducing the difficulty of operation.

[0022] In some embodiments, the locking assembly 31 includes a sliding assembly 311 and a pressure rod 312. The sliding assembly 311 and the pressure rod 312 are respectively disposed on both sides of the fixing member 323 in the thickness direction. Both ends of the fixing member 323 in the length direction are respectively connected to a sliding assembly 311, and the sliding assembly 311 is slidably connected to the housing 1. One end of the pressure rod 312 is connected to a limiting member 321, and the other end of the pressure rod 312 presses against the side of the fixing member 323 away from the sliding assembly 311, and the pressure rod 312 can be flipped relative to the fixing member 323. The sliding assembly 311 is mainly used to enable the cleaning assembly 32 to slide and connect with the housing 1, thereby improving the stability of the dust removal process of the cleaning assembly 32. The pressure bar 312 is used to change the relative positional relationship between the scraper 322, the fixing member 323, and the pre-filter 2, so that the scraper 322 can press against the surface of the pre-filter 2 in the specified dust removal direction, and can also separate from the surface of the pre-filter 2 during the reset process of the scraper 322, thus preventing large particles of impurities from being carried back to the surface of the pre-filter 2 during the reset process of the scraper 322.

[0023] In some embodiments, the sliding assembly 311 includes a slider 3111 and a spring latch 3112. One end of the slider 3111 is connected to the fixing member 323 via the spring latch 3112, and the other end of the slider 3111 is disposed opposite to the fixing member 323 in the thickness direction and has a clearance space between it and the fixing member 323 for the housing 1 to be inserted. The spring latch 3112 is provided to facilitate quick assembly and disassembly of the cleaning assembly 32 from the housing 1 and to fix the position of the cleaning assembly 32 in the height direction of the housing 1. Specifically, when the slider 3111 moves the scraper 322 to a designated position, the spring latch 3112 is pressed, and the spring latch 3112 locks the slider 3111 to the housing 1, thereby fixing the relative position of the slider 3111 and the cleaning assembly 32 to the housing 1.

[0024] In some embodiments, the connecting assembly 324 includes a fixing post 3241, a sleeve 3242, and a resetting member 3243; the fixing post 3241 is connected to the fixing member 323, and the sleeve 3242 is connected to the scraper 322; the sleeve 3242 is movably sleeved on the outside of the fixing post 3241, and the resetting member 3243 is sleeved on the outside of the fixing post 3241 and sandwiched between the sleeve 3242 and the fixing member 323. The resetting member 3243 is provided to push the sleeve 3242 away from the fixing post 3241 after the cleaning assembly 32 is unlocked, so that the scraper 322 presses against the surface of the pre-filter 2.

[0025] In some embodiments, a limiting portion 3245 is provided at the end of the fixing post 3241 away from the fixing member 323; the limiting portion 3245 can abut against the sleeve 3242 in the axial direction of the fixing post 3241. Preferably, the outer diameter of the limiting portion 3245 is larger than the outer diameter of the fixing post 3241 and smaller than the inner diameter of the sleeve 3242. The limiting portion 3245 is provided to limit the relative positional relationship between the fixing post 3241 and the sleeve 3242, ensuring that the fixing post 3241 and the sleeve 3242 maintain a connection relationship.

[0026] In some embodiments, a groove 3211 is formed on the circumferential sidewall of the limiting member 321, and the groove 3211 is provided through the limiting member 321 radially; one end of the pressure rod 312 has a locking rod 3121, which engages with the groove 3211. The groove 3211 and the locking rod 3121 cooperate to allow them to rotate relative to each other and engage, thereby improving the tightness of the connection between the pressure rod 312 and the limiting member 321.

[0027] In some embodiments, the housing 1 is provided with a sliding channel 12 that matches the slider 3111. Specifically, the slider 3111 is provided with two opposing first blocking blocks 3114 on the side facing the housing 1. Correspondingly, the housing 1 is provided with four second blocking blocks 14, and every two second blocking blocks 14 are arranged opposite each other to form a sliding channel 12. The first blocking blocks 3114 are embedded in the corresponding sliding channel 12 to limit the degree of freedom of the slider 3111 in the length direction of the cleaning component 32 and improve stability.

[0028] In some embodiments, a dust collection box 13 is provided at the bottom of the housing 1; the dust collection box 13 is disposed opposite to the cleaning component 32. Specifically, the opening 131 of the dust collection box 13 is provided at the top. When the cleaning component 32 slides from top to bottom, it can push the impurities on the surface of the pre-filter 2 into the dust collection box 13 for collection, ensuring the dust removal effect.

[0033] In this embodiment, the sliding assembly 311 includes a slider 3111 and a spring latch 3112; one end of the slider 3111 is connected to the fixing member 323 via the spring latch 3112, and the other end of the slider 3111 is disposed opposite to the fixing member 323 in the thickness direction and has a clearance space between it and the fixing member 323 for the housing 1 to be inserted. Specifically, a cover 3113 is also provided on the slider 3111.

[0034] In this embodiment, the connecting assembly 324 includes a fixing post 3241, a sleeve 3242, and a resetting member 3243; the fixing post 3241 is connected to the fixing member 323, and the sleeve 3242 is connected to the scraper 322; the sleeve 3242 is movably sleeved on the outside of the fixing post 3241, and the resetting member 3243 is sleeved on the outside of the fixing post 3241 and sandwiched between the sleeve 3242 and the fixing member 323. Preferably, the resetting member 3243 is a compression spring.

[0035] In this embodiment, a limiting part 3245 is provided at the end of the fixing post 3241 away from the fixing member 323; the limiting part 3245 can abut against the sleeve 3242 in the axial direction of the fixing post 3241.
