Technical Field

[0001] This utility model belongs to the field of air sterilizer technology, specifically a ceiling-mounted air filtration and sterilizer. Background Technology

[0002] Air purifiers are machines that disinfect air through filtration, purification, and sterilization. Current air purifiers typically have pre-filters and fine filters inside to remove impurities such as hair, dust, and insects. Over time, these impurities accumulate on the filters, reducing the filtration efficiency. Therefore, regular maintenance and replacement of the internal filters are necessary. However, replacing the filters in current air purifiers requires removing the cover to access the filters. These covers are often installed using clips, which are designed with a straight tooth pattern for installation and a twisted tooth pattern for removal. This significantly increases the difficulty of disassembly and makes the clips fragile after prolonged use. Improper external force can easily damage or deform the clips, further complicating filter maintenance and replacement. Utility Model Content

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] Reference Figure 1-3 As shown, a ceiling-mounted air filtration and sterilization machine includes a middle shell 1, a lower shell 2 located at the bottom of the middle shell 1, and an upper shell 3 located at the top of the middle shell 1. The middle shell 1, lower shell 2, and upper shell 3 are interconnected. A mounting groove 4 is provided on the front end face of the lower shell 2. A maintenance port 5 is provided on the lower shell 2 inside the mounting groove 4. A primary filter 6 and a fine filter 7 are arranged at intervals from bottom to top inside the maintenance port 5. The fine filter 7 has a higher filtration accuracy than the primary filter 6. They work together to filter dust, hair, flying insects, foreign objects, etc. from the outside air. The dual filtration improves the filtration efficiency. The fine filter 7 can be a HEPA high-efficiency particulate filter. Both the primary filter 6 and the fine filter 7 are composed of a frame and a mesh surface. The frame slides into the limiting groove 501. Limiting grooves 501 matching the primary filter 6 and the fine filter 7 are provided on the inner walls of both sides of the maintenance port 5. A hinge is provided inside the mounting groove 4 on one side of the maintenance port 5. The connector 8 has a baffle 9 hinged to it, which closes the maintenance port 5. A locking hole 10 is provided on the side of the baffle 9 away from the connector 8. A locking assembly matching the locking hole 10 is slidably mounted on the lower housing 2. When it is necessary to disassemble and maintain the primary filter 6 and the fine filter 7, the locking assembly slides on the lower housing 2, separating from the locking hole 10. The baffle 9 flips through the connector 8, moving away from the mounting groove 4, thus opening the maintenance port 5, allowing the operator to access the maintenance port 5. Inside the limiting slide groove 501 of the maintenance port 5, the primary filter 6 and the fine filter 7 are pulled out for replacement and cleaning. The new primary filter 6 and fine filter 7 are then placed into the maintenance port 5 through the limiting slide groove 501. The baffle 9 is then flipped over to block the maintenance port 5. The locking component is then slid into the locking hole 10 to lock the baffle 9. This process does not require the operator to disassemble the housing, making it simple and convenient. It also makes the maintenance of the primary filter and fine filter more efficient and convenient in the future.

[0016] The locking assembly includes a mounting hole 1101, a sliding groove 1102, a locking rod 1103, a slider 1104, a spring 1105, a lever 1106, and a clearance groove 1107. The mounting hole 1101 is formed on the lower housing 2 on one side of the mounting groove 4, and the mounting hole 1101 communicates with the mounting groove 4. The sliding groove 1102 is formed on the inner wall of the mounting hole 1101. The locking rod 1103 is disposed inside the mounting hole 1101, and the slider 1104 is sleeved on the locking rod 1103. 104 is slidably connected to the slide groove 1102. The spring 1105 is sleeved on the locking rod 1103. One end of the spring 1105 abuts against the slider 1104, and the other end abuts against the inner wall of the mounting hole 1101. The lever 1106 is set on the front end face of the locking rod 1103. The clearance groove 1107 is opened on the front end face of the lower housing 2 and communicates with the mounting hole 1101. The front end face of the lever 1106 passes through the clearance groove 1107 and extends to the outside of the clearance groove 1107. When the spring 1105 is in force... Under the action of the locking rod 1103, one side penetrates the mounting hole 1101 and extends into the locking hole 10. The clearance groove 1107 cooperates with the lever 1106, which allows the operator to drive the horizontal movement of the locking rod 1103 from outside the lower housing 2. When it is necessary to open the baffle 9, the lever 1106 is pushed, which drives the locking rod 1103 and the slider 1104 to move horizontally along the slide groove 1102 away from the locking hole 10, and compresses the spring 1105, causing it to... The elastic deformation separates the locking rod 1103 from the locking hole 10, thus separating the baffle 9 from the maintenance port 5. When it is necessary to close the baffle 9, the baffle 9 enters the mounting groove 4. After the locking hole 10 aligns with the mounting hole 1101, the lever 1106 is released, the spring 1105 returns to its original position, and the locking rod 1103 and the slider 1104 are driven to move horizontally to one side of the locking hole 10, so that the locking rod 1103 enters the locking hole 10. The front end face of the baffle 9 is flush with the front end face of the lower housing.

[0017] The bottom of the lower housing 2 has an air inlet, and the periphery of the upper housing 3 has an air outlet. The middle housing is also equipped with an exhaust fan, ultraviolet lamp, plasma module, ozone generator, etc., so that outside air enters from the air inlet of the lower housing 2, is filtered by the primary filter 6 and the fine filter 7, and then sent into the middle housing 2 for disinfection, and then discharged from the air outlet of the upper housing 3 to purify and disinfect the air.

[0018] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
