Description

Technical Field

[0001] This utility model relates to the field of industrial vacuum cleaner technology, and in particular to an industrial vacuum cleaner with sterilization function. Background Technology

[0002] Industrial vacuum cleaners are high-powered cleaning devices designed specifically for industrial environments. They can efficiently remove industrial waste such as metal shavings, dust, and oil stains, and are characterized by strong suction, large capacity, and durability.

[0003] However, traditional industrial vacuum cleaners lack effective sterilization and disinfection mechanisms during actual use. The dusty air they draw in only undergoes simple filtration, and bacteria and viruses in the air cannot be killed. This not only fails to provide a healthy and safe air environment for industrial environments, but may also pose a potential threat to the health of production equipment and personnel due to the growth of harmful microorganisms in the air. Secondly, after a period of use, a large amount of dust easily accumulates on the surface of the filter cartridge of traditional industrial vacuum cleaners, clogging the pores of the filter cartridge and causing a significant decrease in the permeability of the filter cartridge, resulting in a significant reduction in filtration efficiency and thus reducing the efficiency of industrial production.

[0004] Prior art 1 (Chinese patent application number CN202022393093.2, application date 2020-10-23) discloses an industrial vacuum cleaner with sterilization and disinfection function. The bottom of the base plate has four omnidirectional wheels movably connected to each corner. A first housing is fixedly connected to the left side of the top of the base plate. A collection box is located at the bottom of the inner cavity of the first housing. Fixed plates are fixedly connected to the middle and bottom of the inner cavity of the collection box. A centrifugal separator is located between opposite sides of the fixed plates. Through the combined use of the collection box, centrifugal separator, liquid storage tank, liquid injection pipe, pump body, first hose, nozzle, ultraviolet lamp, horizontal pipe, HEPA filter, and activated carbon mesh, it has the advantage of sterilization and disinfection. This solves the problem that existing industrial dust collectors cannot sterilize and disinfect the inhaled dust during the dust removal process, and harmful substances such as bacteria and viruses accumulate on the filter element, continuously growing and endangering human health and polluting the environment.

[0005] Prior art 2 (Chinese patent application number CN202411835624.5, application date 2024-12-13) discloses an industrial vacuum cleaner with sterilization and disinfection function. The outer wall of the shell has an exhaust groove, and a fan for generating negative pressure and a cyclone assembly are fixedly connected in the exhaust groove. The cyclone assembly mainly consists of a cyclone chamber and a dust collection box. An air inlet pipe is fixedly connected to the side of the shell away from the fan. The air inlet pipe extends into the shell and is fixedly connected to the cyclone chamber. Through the sterilization assembly, high-temperature steam can be mixed with room temperature air when the industrial dust collector is vacuuming, so that the bacteria in the dust are heated by the high-temperature steam. The high-temperature steam coagulates and denatures the bacterial proteins, thereby achieving the purpose of sterilization. Utility Model Content

The dust collection box 44 collects dust and other particulate matter.

[0021] The filter box 42 is equipped with a mounting bracket 45, which provides a mounting base for the filter element 46. Several filter elements 46 are mounted on the mounting bracket 45. The filter element 46 is composed of HEPA filter and ULPA filter, which intercepts dust and other particulate matter. The filter box 42 is equipped with a sterilization box 49. The bottom of the sterilization box 49 is provided with ventilation openings 410 corresponding to the positions of the filter elements 46. The ventilation openings 410 allow the air that has been filtered by the filter cartridge and disinfected by the disinfectant to continue to enter the sterilization box 49.

[0022] The top of the sterilization box 49 is equipped with a dust collection box 411, and a second mounting bracket 412 is installed inside the dust collection box 411. The second mounting bracket 412 provides a mounting base for the blower 413. The blower 413 is installed on the second mounting bracket 412. The suction end of the blower 413 is connected to the top of the sterilization box 49 through a pipe. When the blower 413 operates, it generates suction to make the air flow. The top of the dust collection box 411 is equipped with a top plate 414, and an exhaust port 415 is provided on the top plate 414. The exhaust port 415 on the top plate 414 is used to discharge the air after sterilization. A sealing cover 416 is threadedly connected to the outside of the exhaust port 415.
