[0023] The following will, with reference to the accompanying drawings, give a detailed description of the preferred embodiments of the present utility model.

[0024] Refer to Figures 1 to 5 , the present utility model provides a circulating suction and blowing cleaning device, including: a frame 1, a suction and blowing combined box 2, a blower 3 and a filter device 4. The filter device 4 is installed in the middle of the frame 1, and the blower 3 is installed at the lower part of the frame 1. An equipment air inlet 5 and an equipment air outlet 6 are provided at the upper part of the frame 1, and the equipment air inlet 5 and the equipment air outlet 6 are connected to the blower 3 through a pipeline via the filter device 4. The filter device 4 is used to filter the air entering from the equipment air inlet 5 and the air blown out from the blower 3, so as to effectively remove dust and impurities in the air, ensure the cleaning effect and the air quality of the working environment, and avoid causing secondary pollution.

[0025] Further, the suction and blowing combined box 2 is provided with a box body air inlet 201, a box body air outlet 202, a blowing port 203 and two dust suction ports 204. The box body air inlet 201 is connected to the equipment air outlet 6 through a pipeline, the box body air outlet 202 is connected to the equipment air inlet 5 through another pipeline, and the two dust suction ports 204 are distributed on both sides of the blowing port 203.

[0026] Among them, a flow guide plate 7 is also installed in the suction and blowing combined box 2. The flow guide plate 7 divides the inner cavity of the suction and blowing combined box 2 into a first air chamber 205 and a second air chamber 206. The box body air inlet 201 is connected to the blowing port 203 through the first air chamber 205, and the box body air outlet 202 is connected to the two dust suction ports 204 through the second air chamber 206. When the blower 3 works, it is used to form a positive pressure in the first air chamber 205, so that the blowing port 203 can blow out a high-speed air flow, and at the same time form a negative pressure in the second air chamber 206, so that the two dust suction ports 204 can suck away the blown-up dust and impurities, etc.

[0027] When the circulating blowing and suction cleaning device of the utility model is working, the air is sucked into the high-speed rotating blower 3 from its air inlet. Under the action of the centrifugal force of its blades, the air is pressurized and blown out from the air outlet. The blown air enters the first air cavity 205 through the pipeline, the air outlet 6 of the device, and the air inlet 201 of the box body, and forms a positive pressure in the first air cavity 205, so that the blowing port 203 can blow out a high-speed air flow to blow up the dust and impurities attached to the surface of the product. At the same time, the air inlet of the blower 3 sucks air from the second air cavity 206 through the pipeline, the air inlet 5 of the device, and the air outlet 202 of the box body to form a negative pressure in the second air cavity 206, and sucks away the blown dust and impurities through the two dust suction ports 204. By using this blowing and suction cooperation, the product can be efficiently and thoroughly cleaned, the cleaning effect can be improved, and the escape of dust and impurities can also be prevented to avoid secondary pollution. At the same time, the circulating blowing and suction can be realized by one blower 3 of the utility model, which can greatly reduce the equipment cost and has the advantages of energy saving and convenient use.

[0028] Refer to Figure 1 and Figure 2 As shown in FIG.

[0029] Among them, both the primary filter 405 and the secondary filter 406 are obtained by purchasing in the market, which are conventional existing technologies, and their structures are similar to the filter cores of vacuum cleaners.

[0030] In this embodiment, the primary filter 405 is a coarse filter, and the secondary filter 406 is a fine filter, that is, the filtration aperture of the secondary filter 406 is smaller than that of the primary filter 405.

[0031] Furthermore, the device air inlet 5 is connected to the first filter chamber 403 through the first pipeline 8, and the first filter chamber 403 is connected to the air inlet of the blower 3 through the second pipeline 9. When the blower 3 is working, the air enters the first filter chamber 403 through the first pipeline 8, and after being filtered by the primary filter 405, it enters the blower 3 through the second pipeline 9.

[0032] The air outlet of the blower 3 is connected to the second filter chamber 404 through the third pipe 10, and the second filter chamber 404 is connected to the equipment air outlet 6 through the fourth pipe 11. When the blower 3 works, the air it blows out enters the second filter chamber 404 through the third pipe 10, and after being further filtered by the secondary filter 406, it enters the air blowing and suction combination box 2 through the fourth pipe 11 and the equipment air outlet 6. In this way, by setting up two-stage filtration, it is ensured that dust and impurities in the air are effectively removed, the cleaning effect and the air quality of the working environment are guaranteed, and secondary pollution is avoided.

[0033] In this embodiment, as Figure 4 shown, the purge port 203 and the two suction ports 204 are both linear and are arranged in parallel at the bottom of the air blowing and suction combination box 2. When the product to be cleaned passes below the air blowing and suction combination box 2, the purge port 203 and the two suction ports 204 are used to comprehensively clean the surface of the product.

[0034] Figure 5 Fig. is a perspective view after removing an end cover plate of the air blowing and suction combination box 2. There are two deflector plates 7 in the air blowing and suction combination box 2, and the two deflector plates 7 are symmetrically distributed. The upper half of each of the two deflector plates 7 is inclined away from each other, so that a pressurizing air duct 701 is formed between the upper halves of the two deflector plates 7. The width of the pressurizing air duct 701 gradually narrows from top to bottom, and the pressurizing air duct 701 is located in the first air chamber 205. The positive pressure gas entering the first air chamber 205 from the box body air inlet 201 can increase the gas pressure under the action of the pressurizing air duct 701.

[0035] Further, a purge block 12 is installed between the lower halves of the two deflector plates 7. The purge block 12 is provided with a blowing nozzle 1201 whose width gradually narrows from top to bottom. The top of the blowing nozzle 1201 leads to the pressurizing air duct 701, and the bottom of the blowing nozzle 1201 is docked to the purge port 203. When the positive pressure gas in the first air chamber 205 flows towards the purge block 12 through the pressurizing air duct 701, the gas pressure can be further increased through the blowing nozzle 1201 with a wider top and a narrower bottom.

[0036] It is worth mentioning that a flow equalizing plate 13 is installed at the upper end of the blowing nozzle 1201 of the purge block 12, and a number of through holes are arranged in the flow equalizing plate 13. After the positive pressure gas in the first air chamber 205 passes through the pressurizing air duct 701, the flow equalizing plate 13, and the blowing nozzle 1201 in sequence and is blown out from the purge port 203, when the positive pressure gas passes through the flow equalizing plate 13, under the action of the number of through holes in the flow equalizing plate 13, not only can the uniformity of gas flow be improved, but also the gas pressure can be further increased.

[0037] In this embodiment, a plurality of casters 14 are installed at the bottom of the frame 1 to facilitate the movement of the equipment and make it convenient to use.

[0038] As can be seen, the circulating blowing and suction cleaning device of the utility model sucks air from its air inlet by means of the high-speed rotating blower 3. The air is pressurized under the action of the centrifugal force of its blades and blown out from the air outlet. The blown air enters the first air chamber 205 through the pipeline, the air outlet 6 of the device, and the air inlet 201 of the box body, and forms a positive pressure in the first air chamber 205, so that the blowing port 203 can blow out high-speed air flow to blow up the dust and impurities attached to the product surface. At the same time, the air inlet of the blower 3 sucks air from the second air chamber 206 through the pipeline, the air inlet 5 of the device, and the air outlet 202 of the box body to form a negative pressure in the second air chamber 206, and sucks away the blown dust and impurities through the two dust suction ports 204. By using this blowing and suction cooperation, efficient and thorough cleaning of the product can be realized, the cleaning effect can be improved, and the escape of dust and impurities can also be prevented to avoid secondary pollution. At the same time, the utility model can realize circulating blowing and suction by one blower 3, which can greatly reduce the equipment cost, and has the advantages of energy saving and convenient use. In addition, by setting the filtering device 4, the dust and impurities in the air can be effectively removed to ensure the cleaning effect and the air quality of the working environment.
