Description

Technical Field

[0001] The utility model relates to a low-vibration desktop purifier. Background Art

[0002] The air purifier uses the internal filter element to filter out dust and other pollutants contained in the inhaled air. These dust and other pollutants will gradually be enriched on the filter element. As the use time increases, the filtering performance of the filter element will deteriorate, and the load of the blower mechanism will also be significantly increased. Therefore, it is necessary to clean or replace the filter element. The air purifier needs to be designed with a structure that is convenient for the disassembly and assembly of the filter element. In addition, small-volume desktop purifiers face the problem of insufficient air intake, so some desktop purifiers use a double-sided air intake blower mechanism to increase the air intake, that is, the blower mechanism has two left and right air inlets on the volute. However, since the motor shaft of the blower is arranged horizontally, when it rotates, the asymmetry of the volute structure will cause obvious vibration and produce abnormal noise.

The filter element module 3 includes a cylindrical filter element 31, the central channel 310 of the cylindrical filter element 31 is directly opposite to the air inlet of the blower mechanism 2, and an air inlet grid 22 is provided at the air inlet, and a plurality of inclined air guide plates 23 are circumferentially provided at the air outlet of the blower mechanism 2; the side of the housing 1 is provided with an air inlet mesh 10, the air inlet mesh 10 is arranged around the side of the housing 1 and is opposite to the outer wall of the cylindrical filter element 31, and the air enters through the air inlet mesh 10 under the action of the blower mechanism 2 and flows through the cylindrical filter element 31 to be filtered and then sent to the blower mechanism 2 through the central channel 310; the machine The bottom end of the housing 1 is provided with a bottom cover 13, and the bottom cover 13 is provided with an opening 130 that penetrates into the housing 1. A plurality of guide edges 132 and a clamping groove 133 located at one end of the guide edge 132 are provided on the inner edge 131 of the opening 130. The filter element module 3 also includes a tray 32 for mounting the cylindrical filter element 31. The tray 32 is a disc, and the center position of the bottom surface thereof is recessed upward so that a bulge 321 is formed on the top surface of the tray 32. The outer edge of the tray 32 is provided with a flange 322 that is folded upward, and a flange 322 for mounting the cylindrical filter element 31 is formed between the flange 322 and the bulge 321. The annular groove 323 of the filter element 31, and a rotating handle 33 is provided in the recessed part of the bottom surface of the tray 32, and a plurality of outwardly protruding clamping blocks 34 are provided on the outer side of the flange 322, and the filter element module 3 is embedded in or removed from the casing 1 through the opening 130 of the bottom cover 13, and the tray 32 is rotated relative to the bottom cover 13 to make the clamping block 34 slide into or out of the clamping groove 133 along the guide edge 132, and the installation and removal of the filter element module 3 from the bottom of the casing 1 is realized through the rotation cooperation between the tray 32 and the bottom cover 13 of the casing 1, which is simple and convenient to operate.

[0025] Specifically, a limiting protrusion 135 capable of elastic reset is provided in the clamping groove 133, and the limiting protrusion 135 has a first slope 135a facing the entrance direction of the clamping groove 133, and a second slope 135b facing away from the entrance direction of the clamping groove 133. The clamping block 34 is provided with an inner concave portion 34a for the limiting protrusion 135 to be embedded. In the design of the elastic reset structure, the present invention adopts the following method: the inner wall of the clamping groove 133 is hollowed out, and one end 135c of the limiting protrusion 135 is connected to the edge of the hollow part so that it yields to the hollow area when under pressure. When the tray 32 rotates until the clamping block 34 contacts the first slope 135a, the limiting protrusion 135 gives way to the hollow area, and then the clamping block 34 continues to slide into the clamping groove 133 until the inner concave portion 34a is opposite to the limiting protrusion 135, and the limiting protrusion 135 is reset and falls into the inner concave portion 34a to be limited. On the contrary, when the tray 32 rotates in the opposite direction until the clamping block 34 contacts the second slope 135b, the limiting protrusion 135 gives way to the hollow area, and then the clamping block 34 continues to slide out of the clamping groove 133, thereby releasing the lock on the tray 32.

[0026] In order to ensure that the bottom cover 13 and the tray 32 are firmly assembled and not easy to loosen, a limiting strip 36 is provided below the clamping block 34. The limiting strip 36 is used to overlap and limit the lower groove edge 133a of the clamping groove 133 when the clamping block 34 slides into the clamping groove 133. The limiting strip 36 has a third slope 36a that contacts the notch of the clamping groove 133 when sliding into the clamping groove 133. When the clamping block 34 slides into the clamping groove 133, the third slope 36a of the limiting strip 36 cooperates with the notch of the clamping groove 133 so that the limiting strip 36 can be guided into the clamping groove 133 and overlap the lower groove edge 133a of the clamping groove 133, and the limiting strip 36 and the lower groove edge 133a are interference-fitted to achieve a firm connection.
