Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a cleaning equipment and its modular lifting system. Background Art

[0002] A cleaning equipment is a ground finishing machine for cleaning the ground, which replaces manual labor to clean the site to be cleaned and is often used in shopping malls, supermarkets and squares. During the use of the cleaning equipment, it is necessary to spray a cleaning liquid on the ground of the site to prevent dust on the ground from being raised during the process of cleaning the ground with a brush disk. After the brush disk cleans, sewage will be generated on the ground of the site, and it is necessary to use a water suction squeegee to suck up the sewage to prevent the sewage from flowing randomly and polluting the site.

[0003] For the existing cleaning equipment, since the ground of the site to be cleaned is often uneven, and the scraping member arranged on the water suction squeegee needs to be attached to the ground when the water suction squeegee sucks up the sewage, the scraping member will inevitably rub against the ground during use, eventually resulting in the damage of the scraping member, causing the water suction squeegee to be unable to normally suck up the sewage, and further resulting in the frequent removal of the water suction squeegee arranged on the cleaning equipment for maintenance.

[0004] In addition, since the brush disk is fixed to the bottom of the ground finishing equipment by a rotating clamping method, when the brush disk needs to be disassembled and replaced due to wear during use, or needs to be disassembled and cleaned due to hair entanglement, it is necessary to prepare a specific tool in advance to rotate the brush disk in the direction opposite to its fixed direction to remove it, making the operation of removing the brush disk from the ground finishing equipment not convenient, and the disassembly of the brush disk is time-consuming.

The sewage suction component 30 which can suck up the sewage left after the cleaning component 20 cleans the ground is disposed on the pulling plate 42 and faces the bottom of the device body 11. In the moving direction of the device body 11, the cleaning component 20 and the sewage suction component 30 are disposed in a front-back positional relationship, and there is a predetermined distance between the sewage suction component 30 and the cleaning component 20 to better suck up the sewage.

[0043] Preferably, the cleaning component 20 includes a suction cup connection structure 21, a cleaning member 22, and a cleaning water tank 23. The cleaning member 22 is disposed on the pulling plate 42 through the suction cup connection structure 21. The cleaning water tank 23 is disposed on the device body 11. The cleaning water tank 23 has a water tank opening 2301 for loading cleaning liquid into the cleaning water tank 23. The cleaning liquid in the cleaning water tank 23 flows through the pipeline through the suction cup connection structure 21 to the cleaning member 22 to realize the cleaning of the ground by the cleaning member 22.

[0044] Preferably, the suction cup connection structure 21 includes a connection main body 211, at least one sub-suction attachment 212, and a driving member 215. The cleaning member 22 includes a suction cup main body 221, a cleaning member 222, and at least one female mounting member 223. The connection main body 211 is disposed on the pulling plate 42. The sub-suction attachments 212 are coaxially arranged in the circumferential direction on the connection main body 211. The female mounting member 223 is disposed at a predetermined position on the upper surface of the suction cup main body 221 and can be magnetically connected to the sub-suction attachments 212, so that the suction cup main body 221 is detachably disposed on the lower surface of the connection main body 211.

The connection main body 211 is coaxially mounted on the output end of the driving member 215. The cleaning member 222 is disposed on the lower surface of the suction cup main body 221 to clean the ground when the connection main body 211 drives the suction cup main body 221 to rotate.

[0045] Those skilled in the art can understand that when the connection main body 211 rotates under the drive of the driving member 215, the suction cup main body 221 realizes rotation through the female mounting member 223 magnetically connected to the sub-suction attachments 212, and further enables the cleaning member 222 to clean the ground under the rotation of the suction cup main body 221.

[0046] Furthermore, since the mother mounting member 223 is disposed on the upper surface of the suction cup main body 221 such that it can be magnetically connected to the sub-suction member 212, the suction cup main body 221 is detachably disposed on the lower surface of the connection main body 211. When the cleaning member 222 is worn due to long-term use or the cleaning member 222 is entangled with hair during use and needs to be replaced or cleaned, the suction cup main body 221 can be smoothly removed from the lower surface of the connection main body 211 without the assistance of additional tools, making the disassembly of the suction cup main body 221 more convenient and efficient.

The cleaning water tank 23 outputs the cleaning liquid to the corresponding liquid spraying port 21101 through a pipeline, so that the cleaning liquid passes through the liquid spraying port 21101 of the connection main body 211 and flows from the liquid spraying through hole 22101 of the suction cup main body 221 to the ground.

[0049] Those skilled in the art can understand that since the connection main body 211 and the suction cup main body 221 are in a rotating state, and since the liquid spraying through hole 22101 is arranged in a circumferential array and coaxially with the connection main body 211 on the connection main body 211, under the action of centrifugal force, the cleaning liquid flowing out from the liquid spraying through hole 22101 will be evenly scattered on the surface of the cleaning member 222 and evenly fall on the position of the ground that needs to be cleaned by the cleaning member 222, preventing the dust on the ground from being raised when the cleaning member 222 cleans the ground and providing guarantee for the environmental hygiene during the operation of the cleaning device.

The scraper component 322 includes a closed scraper 3221 and a water-blocking scraper 3222. The closed scraper 3221 and the water-blocking scraper 3222 are connected end to end to form a sewage absorption chamber 32201 connected to the sewage outlet 32101. The closed scraper 3221 and the water-blocking scraper 3222 are arranged below the squeegee body 321.

[0057] It is worth mentioning that by adjusting the tightening degree of the adjusting bolt 3142, and then adjusting the distance between the adjusting plate 3141 and the connecting plate 3131, the predetermined distance between the scraper member 322 of the water absorbing structure 32 and the ground can be adjusted, so that the scraper member 322 of the water absorbing structure 32 can better fit the ground, thereby avoiding the situation where the scraper member 322 cannot better fit the ground due to wear.

[0058] Preferably, the closing scraper 3221 and the water-blocking scraper 3222 are configured to have a predetermined shape, and a predetermined length of the closing scraper 3221 and the water-blocking scraper 3222 is greater than a predetermined width of the suction cup body 221 .

[0059] Specifically, the closed scraper 3221 and the water-blocking scraper 3222 are arranged front and back in the forward direction of the equipment body, and the predetermined width of the water-blocking scraper 3222 is greater than the predetermined width of the closed scraper 3221, so that when the water-blocking scraper 3222 is close to the ground, a sewage suction port 32202 connected to the sewage suction chamber 32201 is formed between the scraper member 322 and the ground for sucking out sewage.

[0060] Those skilled in the art can understand that sewage is sucked into the sewage suction cavity 32201 from the sewage suction port 32202 of the scraping member 322, and passes through the sewage discharge port 32101 of the water suction scraper main body 321, and enters the sewage tank main body 331 through the pipeline between the water suction scraper main body 321 and the sewage tank main body 331, finally realizing the collection of sewage generated after the cleaning assembly 20 cleans the ground.

[0061] It is worth mentioning that the device main body 10 further includes a protection plate 12, which is arranged at the lower part of the equipment main body 11 and is used to prevent the water suction scraper connection structure 31 from being exposed to the outside, enhancing the integrity and aesthetics of the cleaning device.

The suction cup main body 221 also has a limiting groove 22102 corresponding to the position of the clamping block 213, and the clamping block 213 is correspondingly arranged in the limiting groove 22102, so that under the drive of the driving member 215, the connection main body 211 can smoothly drive the suction cup main body 221 to rotate, avoiding the cleaning member 22 from detaching from the bottom of the equipment main body 11 due to the insecure adsorption between the sub-suction member 212 and the mother mounting member 223, and avoiding threatening the safety of pedestrians near the cleaning device.

[0063] Preferably, the suction cup connection structure 21 further includes a water blocking ring 214, which is coaxially arranged on the connection main body 211, and the water blocking ring 214 is arranged on the outer periphery of the liquid spraying through hole 22101 and fits on the suction cup main body 221 to prevent the cleaning liquid sprayed from the liquid spraying port 21101 from entering the limiting groove 22102 through the gap between the connection main body 211 and the suction cup main body 221 during the process of being evenly sprinkled on the surface of the cleaning member 222 through the liquid spraying through hole 22101 of the suction cup main body 221 under the rotation of the connection main body 211, which may cause the clamping block 213 to slide in the limiting groove 22102 of the suction cup main body 221, and finally the water blocking ring 214 prevents the suction cup main body 221 from falling off the lower surface of the connection main body 211, thereby avoiding injuring pedestrians near the cleaning device due to the falling off of the suction cup main body 221.
