Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to an industrial vacuum cleaner with a filter element that is easy to disassemble, assemble and replace. Background Art

[0002] Industrial vacuum cleaners use motors to drive high-voltage extensions to generate negative pressure in a limited volume, thereby generating suction. Existing industrial vacuum cleaners have some defects. First, the industrial vacuum cleaner needs to be moved when in use to vacuum different areas. Therefore, the industrial vacuum cleaner needs to be connected to a very long wire. However, the wires need to be manually arranged after use, which is extremely inefficient and laborious. Second, the industrial vacuum cleaner uses the suction head to vacuum. However, it is difficult to inhale the dust on the ground that is highly sticky, making the device inconvenient to use. Among them, the application number is "CN202320937664.5" for an industrial vacuum cleaner. This utility model The new model adds a winding mechanism for quick winding of the wires, avoiding the need to spend a lot of time on evenly arranging the wires after use, making the device more practical. Secondly, the device adds a sweeping and brushing function to the suction head mechanism, which not only has a vacuuming effect, but also has a sweeping and brushing effect on the ground, effectively preventing sticky impurities from being sucked into the device. However, there is still room for improvement in the use of this vacuum cleaner: industrial vacuum cleaners have a large cleaning capacity, so the filter needs to be replaced and cleaned frequently. Usually the filter is installed inside the negative pressure cylinder to filter the sucked impurities. Since it is inconvenient to disassemble, it takes a lot of time for subsequent cleaning, which affects its use. Utility Model Content

[0003] The purpose of the utility model is to provide an industrial vacuum cleaner with easy disassembly, assembly and replacement of filter elements, so as to solve the problem that the industrial vacuum cleaner proposed in the above background technology has a large cleaning volume and thus requires frequent replacement and cleaning of the filter screen. Usually, the filter screen is installed inside the negative pressure cylinder to filter the sucked impurities. Since it is inconvenient to disassemble, it takes a lot of time for subsequent cleaning, which affects the use.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an industrial vacuum cleaner that is easy to disassemble and replace the filter element, comprising a base, a dust collection assembly and a quick-release assembly;

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) After the filter cartridge is installed inside the negative pressure cartridge, rotate the filter cartridge to drive the block to contact the limit block. Since the block and the limit block are in a corresponding triangular wedge structure, the block pushes the limit block to move backward and drives the spring on the connecting rod surface to compress and store force. When the block moves to the back of the limit block, the spring resets to drive the connecting rod to move and push the limit block to limit the block to prevent the block from moving and causing the filter cartridge to loosen. When disassembling, pull the lever to drive the limit block at one end of the connecting rod to retreat, so that the limit block moves away from one side of the block. At this time, rotate according to the indicator arrow engraved on the top of the support ring to disassemble the filter cartridge, which is convenient for replacement and cleaning, and reduces the time spent on cleaning;
