[0002] In industrial production, enterprises involved in the production of aluminum powder, zinc powder, ferrosilicon powder, etc. are more likely to produce flammable and explosive dust particles in industrial sites. These highly dangerous explosive conductive dusts may explode at any time. The dust is usually absorbed and processed by explosion-proof vacuum cleaners.

[0003] The patent specification with the announcement number CN215078001U discloses a pneumatic explosion-proof vacuum cleaner, including a vacuum cleaner body, a hose connected to the side of the vacuum cleaner body, a metal pipe connected to the end of the hose, a grip sleeve provided on the outside of the metal pipe, a dust scraper connected to the bottom of the metal pipe, a first spring provided inside the rear end protrusion of the dust scraper, a clamping rod passing through the inside of the first spring, a connecting seat connected to the end of the clamping rod, and a mop head fixed to the bottom of the connecting seat. The pneumatic explosion-proof vacuum cleaner can clean the area after vacuuming through the added mop head, and vacuuming and cleaning can be completed simultaneously, which reduces the workload of users and improves their work efficiency. The mop head and the dust scraper are connected through the clamping of the clamping rod and the connecting seat, which is convenient for users to replace the aged and damaged mop head in time, ensuring the normal use of the mop head.

[0004] However, in the implementation of relevant technologies, it was found that the pneumatic explosion-proof vacuum cleaner of the above design has the following problems: in the prior art, the vacuum cleaner is equipped with a mop head, which allows the vacuum cleaner to have multiple functions of vacuuming and cleaning at the same time, but in actual use, the vacuum cleaner needs to be disassembled and maintained at regular intervals to avoid clogging over time. In view of this, a pneumatic explosion-proof vacuum cleaner with a dust suction end that is easy to replace and maintain is provided to overcome the above defects. Utility Model Content

[0023] Reference Figure 1-4 The utility model provides a pneumatic explosion-proof vacuum cleaner with a dust suction end that is easy to replace and maintain: comprising a dust suction device 1, a delivery hose 2 is passed through one side of the outer wall of the dust suction device 1, a handle 3 is passed through the other end of the delivery hose 2 away from the dust suction device 1, and a dust suction end mechanism 4 is arranged on one side of the handle 3;

[0024] The dust collection end mechanism 4 includes a ventilator 401, which is sleeved on one end of the handle 3. A conveying box 402 is sleeved on the end of the ventilator 401 away from the handle 3. The front end of the conveying box 402 is connected to a dust collection shell 403. A filter 404 is embedded in the outer wall of the dust collection shell 403. A static elimination rod 405 is arranged inside the dust collection shell 403. A dustproof cloth 406 is arranged between the static elimination rod 405 on one side of the filter 404. The static elimination rod 405 removes the electric charge between the dust to avoid the explosion of dust during circulation.

[0025] As a further implementation scheme of the above technical scheme: the size of the dustproof cloth 406 matches the size of the filter 404, and the dustproof cloth 406 fits tightly against the filter 404, so that the dust passes through the filter 404 and directly enters the conveying box 402 to avoid diffusion and thus difficulty in dust collection.

[0026] As a further implementation scheme of the above technical scheme: a motor 5 is embedded inside the conveying box 402, and a driving rod 6 is connected to the power output end of the motor 5. One end of the driving rod 6 passing through the filter screen 404 is connected to a scraper 7. The driving rod 6 is driven by the motor 5 to allow the scraper 7 to rotate in contact with the filter screen 404, thereby scraping off the adsorbed dust to avoid accumulation and clogging.

[0027] During specific implementation, the handle 3 is threadedly connected to the conveying hose 2, which is convenient for the disassembly, assembly and maintenance of the dust suction end mechanism 4. The filter 404 prevents larger impurities and debris from entering, and cooperates with the static elimination rod 405 to prevent dust charges from colliding with each other and causing explosion. The dust suction shell 403 allows dust to directly enter the conveying box 402 through the fixed dustproof cloth 406 to avoid adsorption on the static elimination rod 405. At the same time, the dustproof cloth 406 does not affect the work of the static elimination rod 405. The motor 5 drives the driving rod 6 to allow the scraper 7 to rotate in contact with the filter 404, thereby avoiding dust accumulation and blockage. The handle 3 is connected to the vent 401, which is convenient for dust to enter the dust suction device 1.

[0028] As a further implementation scheme of the above technical scheme: a limiting ring 8 is fixed below the front end conveying hose 2 of the dust suction device 1, and a placement shell 9 is arranged below the limiting ring 8 at the front end of the dust suction device 1. The limiting ring 8 is convenient for limiting the dust suction end mechanism 4 when it is not in use, and the placement shell 9 is convenient for limiting and placing the dust suction end mechanism 4.

[0029] As a further implementation scheme of the above technical scheme: a cleaning mechanism 10 is arranged on one side of the housing shell 9, and the cleaning mechanism 10 includes a water tank 1001, which is fixed on one side of the housing shell 9, and a pump 1002 is embedded on one side of the inner side of the water tank 1001, and the output end of the pump 1002 is connected to a water pipe 1003, and the end of the water pipe 1003 away from the pump 1002 is sleeved with a connecting sleeve 1004, and a water outlet roller 1005 is passed through the interior of the connecting sleeve 1004, and the outer rotation of the water outlet roller 1005 is connected to a sponge layer 1006, and the water pipe 1003 is a hose, which is convenient for bending and moving with the dust suction end mechanism 4, and the water source in the water tank 1001 is convenient to be drawn through the pump 1002 and the water pipe 1003, and supplied to the water outlet roller 1005 to spray on the sponge layer 1006, so as to scrub the object or the ground.

[0030] As a further implementation scheme of the above technical scheme: the connecting sleeve 1004 is snap-connected with the water pipe 1003, and the connecting sleeve 1004 is threadedly connected with the water outlet roller 1005. After the connecting sleeve 1004 is rotated and snap-connected with the water pipe 1003, it is threadedly connected to the water outlet roller 1005, which is convenient for disassembly and assembly, thereby facilitating the disassembly and assembly of the dust collection end mechanism 4.

[0031] As a further implementation scheme of the above technical scheme: the water outlet roller 1005 is connected to the water tank 1001 through the water pipe 1003 and the pump 1002, and a rotating structure is formed between the water outlet roller 1005 and the sponge layer 1006. The cross-section of the sponge layer 1006 is a circular ring structure, which is mounted on the outside of the water outlet roller 1005 and can be scrubbed and cleaned after being moistened by water.

[0032] In specific implementation, water is drawn from a pump 1002 and transported through a water pipe 1003 , which is connected to a water outlet roller 1005 via a connecting sleeve 1004 , so that the water flows out through a through hole in the water outlet roller 1005 and wets the sponge layer 1006 , thereby allowing cleaning while vacuuming.
