[0029] In order to make the technical scheme and advantages of the present application clearer, the present application will be described in detail below in combination with the drawings and specific embodiments.

[0030] As shown in Figures 1-10 , the air strike type negative oxygen ion air purifier of the present application comprises a main body part 100 and a blowing part 200, wherein the blowing part 200 is located above the main body part 100.

[0031] The main body part 100 comprises a main body part shell 101, which has a cavity inside, and an air pump 300 is arranged in the cavity; the blowing part 200 comprises a blowing part shell 201, an air extractor 400 and an air strike type negative oxygen ion generator 500, wherein the air extractor 400 is installed in the blowing part shell 201, and the air strike type negative oxygen ion generator 500 is installed in or outside the blowing part shell 201; for example, the blowing part shell 201 and the main body part shell 101 are both four straight-through cylindrical bodies, the lower end of the blowing part shell 201 is fixedly connected to the upper end of the main body part shell 101 by screws or buckles, and a sealing vibration reduction strip is arranged at the connecting part; the air extractor 400 is arranged at the central part of the blowing part shell 201, and an isolation net or an isolation window is arranged at the upper end of the blowing part shell 201 to prevent foreign matters from entering and damaging the blades of the air extractor 400 and causing safety hazards.

[0032] The air pump 300 is connected with the air-impact type negative oxygen ion generator 500, and is used to provide compressed air to the air-impact type negative oxygen ion generator 500; the air extractor 400 is used to extract air from the main body part 100 and blow out from the air outlet 202 of the blowing part 200; and the negative oxygen ion air outlet 501 of the air-impact type negative oxygen ion generator 500 is aligned with the air outlet 202 of the blowing part 200.

[0033] In operation: the air pump 300 is started to generate compressed air, which is provided to the air-impact type negative oxygen ion generator 500, and collides with water in the air-impact type negative oxygen ion generator 500 to generate negative oxygen ion gas, which is sprayed from the negative oxygen ion air outlet 501. At the same time, the air extractor 400 is operated to extract air from the main body part 100 and blow out from the air outlet 202 of the blowing part 200. The high-speed air collides with the negative oxygen ion gas, and drives the negative oxygen ion gas to move far away, thereby improving the diffusion speed of the negative oxygen ion gas.

[0034] The air-impact type negative oxygen ion air purifier of the present application adopts a modular design structure, and the main body part 100 and the blowing part 200 are detachably connected. The structure design is reasonable, and the air-impact type negative oxygen ion air purifier is convenient to install, disassemble and maintain, and does not affect the overall working performance. In addition, the air extracted by the air extractor 400 enters the chamber from the lower part of the main body part 100 and flows around the air pump 300, so that the heat generated by the pump 300 can be taken away to cool the pump 300, thereby avoiding damage caused by heat dissipation of the pump 300 during operation, and without the need to set up a separate cooling component, the cost is reduced.

[0035] In one embodiment, the main body part 100 and the blowing part 200 are detachably connected, for example, by threaded connection, clamping or the like.

[0036] In one embodiment, the air outlet 202 is located at the top of the blowing part 200, the rotating shaft 420 of the air extractor 400 is vertically arranged, and the negative oxygen ion air outlet 501 of the air-impact type negative oxygen ion generator 500 is horizontally arranged, so that the negative oxygen ion gas collides with the air outlet 202 vertically. By using such a scheme, the air flow path of the air extractor 400 is from bottom to top without bending, and the air flow is more smooth.

[0037] In an embodiment, the main body part 100 comprises an inner housing 110, which is arranged in the main body part shell 101, and the air pump 300 is arranged in the inner housing 110; wherein the inner housing 110 comprises a bottom wall 111 and a cylindrical side wall 112 arranged above the bottom wall, and an air inlet 113 is arranged on the bottom wall, the inner diameter of the side wall 112 is a tapered structure with a larger upper end radius and a smaller lower end radius, and there is a gap between the lower end of the inner surface of the side wall 112 and the air pump 300 (here, the radius refers to the equivalent radius, if it is a rectangle, polygon or other non-circular shape, it is the average value of the distance from the center to each side). Generally, the inner housing 110 is made of a molded plastic part, or a metal punched part. With such a scheme, the air flow of the air inlet 113 has a significant suction effect, making the cooling effect of the air pump 300 better, and the air flow entering the air blower 400 is also large. In an embodiment, the inner housing 110 further comprises a strong rib 114 arranged inside and an outer wall 115, and the outer wall 115 forms a triangular structure with the side wall 112, which enhances the strength of the inner housing 110 as a whole.

[0038] In an embodiment, it further comprises an air pump cover 310, which is a cylindrical structure, the upper end of which is fixed to the blowing part shell 201, and the air pump 300, an air inlet damping silencer 321 and an air outlet damping silencer 320 are arranged in the air pump cover 310, wherein the air inlet damping silencer 321 is arranged at the bottom of the air pump cover 310 and connected with the air inlet of the air pump 300, and the air outlet of the air pump 300 is connected with the air outlet damping silencer 320. In an embodiment, it further comprises an air pump damping device 330, wherein the air pump 300 is fixed to the bottom of the air pump cover 310 or arranged on the partition strip of the side wall of the air pump cover 310 by the air pump damping device, and the material of the air pump damping device is spring or rubber. With such a scheme, the air pump 300 is suspended on the blowing part 200 and is not fixedly connected with the main body part 100, the vibration of the air pump 300 is damped through the blowing part 200 and connected with the main body part 100, so that the vibration is basically not directly transmitted to the bottom surface through the main body part 100, and the vibration noise is reduced.

[0039] In one embodiment, the air pump cover 310 is connected to the blowing part shell 201 by elastic damping. In one preferred embodiment, a plurality of damping assemblies 700 are used, for example three or four, evenly arranged around the top end of the air pump cover 310. Specifically, the damping assembly 700 includes an elastic sleeve 710 and a support rod 720, a mounting hole is provided at the bottom of the blowing part shell 201 for mounting the damping assembly 700, and a connecting bracket 311 is provided on the side wall of the air pump cover 310, wherein the elastic sleeve 710 is partially arranged through the mounting hole and is supported by the blowing part shell 201 at the edge of the mounting hole, the support rod 720 is arranged in the elastic sleeve 710, wherein the top end 721 of the support rod 720 is thick in diameter and is supported at the top of the elastic sleeve 710, the middle section 722 of the support rod 720 is sleeved in the elastic sleeve 710, and the lower end 723 of the support rod 720 is fixedly connected to the connecting bracket 311 (for example, by a threaded structure). With such a structure, the air pump 300, the air pump cover 310, the silencer and other components are not in direct contact with the blowing part shell 201, the weight is transmitted to the support rod 720 through the connecting bracket 311, and then transmitted to the elastic sleeve 710 through the top end of the support rod 720, and then transmitted to the blowing part shell 201 through the elastic sleeve 710. In the working process, the vibration force is also transmitted in the same way, and is absorbed by the elastic sleeve 710 in the transmission process, thereby reducing the vibration and achieving better damping effect.

[0040] In one embodiment, the elastic sleeve 710 includes a supporting part 711, a clamping part 712 and a passing part 713, wherein the passing part 713 is a tapered structure, the maximum outer diameter thereof is slightly larger than the diameter of the mounting hole, and the cross-sectional thickness thereof is smaller than that of the clamping part 712 and the supporting part 711; the outer diameter of the clamping part 712 is adapted to the diameter of the mounting hole; the outer diameter of the supporting part 711 is larger than the diameter of the mounting hole, and the cross section of the supporting part 711 is a serpentine structure, and the outer diameter of the contact part of the supporting part 711 is larger than that of other parts of the elastic sleeve 710. During installation, the passing part 713 of the elastic sleeve 710 gradually passes through the mounting hole, and the maximum outer diameter thereof is deformed to pass through the mounting hole, and then the clamping part 712 enters the mounting hole and clamps the supporting part 711 above the mounting hole. With such a structure, the damping effect is better, and the elastic sleeve 710 is more stable during work and will not collapse locally. Moreover, the installation is more simple and convenient, and the elastic sleeve 710 is not easy to fall out of the mounting hole.

The filter barrel 120 is made of a material with small pore size, such as fiber cloth or sponge, and is fixed on a holder. The filter barrel 120 includes a barrel body 121 and a filter barrel connector 122 fixedly connected to the upper end of the barrel body 121. A positioning connector 220 is arranged on the bottom of the blowing part shell 201. The positioning connector 220 is in the form of a ring or a plurality of arcs (for example, a plurality of arcs formed by a plurality of notches in the ring). The filter barrel connector 122 is fixedly connected to the positioning connector 220. The fixed connection can be a screw connection. Alternatively, the fixed connection can be a clamping connection. For example, the upper end of the filter barrel connector 122 includes a transverse protrusion and has a certain elasticity. A groove is arranged at a position of the positioning connector 220. The transverse protrusion can pass through the inner cavity of the positioning connector 220 by deforming the filter barrel connector 122, and the groove can clamp the transverse protrusion by restoring the original shape. In this way, air can enter the air pump cover 310 only after passing through the filter barrel 120, so that dust particles in the air can be filtered out, and the air entering the air pump 300 and the air blower 400 is more pure, thereby avoiding damage to the air impact type negative oxygen ion generator 500 and the air blower 400. Moreover, the above-mentioned mounting method is more simple and convenient.

[0042] In one embodiment, a primary filter screen 130 is arranged at the lower end of the main body shell 101.
