Description

Technical Field

[0001] The present invention relates to a vacuum cleaner, and in particular to a new type of wet-dry dual-use vacuum cleaner. Background Art

[0002] With the development of the economy and the improvement of living standards, household vacuum cleaners have been widely used. Currently, household vacuum cleaners are mainly dry vacuum cleaners, which only have the function of sucking dust. Dry vacuum cleaners are mainly used to suck dust and other dry contaminants. The filter screen on the dry vacuum cleaner is easy to be blocked and needs to be removed and cleaned regularly. Otherwise, it is easy to block the filter screen and cause the filtration efficiency to be greatly reduced, which is very troublesome and not easy to use. Although there are also wet-dry dual-use vacuum cleaners in the market, that is, vacuum cleaners with both dust suction and water suction functions, however, the separation efficiency of such traditional wet-dry dual-use vacuum cleaners during dust suction is relatively low, and their filtration systems are easily blocked by dust, resulting in the reduction of the performance of the vacuum cleaner and poor dust suction effect. It also needs to be disassembled and cleaned regularly, which is very troublesome and not conducive to frequent use.

[0003] Chinese Utility Model Patent CN 209220118 U discloses a wet-dry dual-use vacuum cleaner. The vacuum cleaner includes a floor brush, a dust suction cavity is defined in the floor brush, and the floor brush has a suction port communicating with the dust suction cavity; an upright body, the body is rotatably connected to the floor brush; a cleaning liquid supply assembly, the cleaning liquid supply assembly includes a cleaning liquid tank and a nozzle, the cleaning liquid tank is arranged on the body and is communicated with the nozzle, and the nozzle is adapted to spray liquid onto the floor brush or the surface to be cleaned; a sewage recovery assembly, the sewage recovery assembly includes a sewage tank communicated with the dust suction cavity, the sewage tank is arranged on the body and is used for recovering sewage, and the sewage tank and the cleaning liquid tank are located on opposite sides of the body; a portable cleaning device, the portable cleaning device is detachably arranged on the body, the portable cleaning device includes a dust collection cylinder assembly and a power assembly, and the air inlet of the dust collection cylinder assembly is communicated with the sewage tank; when the portable cleaning device is in the combined use mode, the portable cleaning device is connected to the body, and under the action of the power assembly, the air flow flows through the dust suction cavity, the sewage tank and the dust collection cylinder assembly in sequence from the suction port; when the portable cleaning device is in the separate use mode, the portable cleaning device is separated from the body and used separately, and under the action of the power assembly, the air flow enters the dust collection cylinder assembly from the air inlet for dust-gas separation. This wet-dry dual-use vacuum cleaner has a filtration system that is easily blocked by dust, poor wet and dry dust suction effects, requires regular disassembly and maintenance, and has a high cost. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned disadvantages of the prior art, and provides a new type of wet-dry dual-use vacuum cleaner with dual wet and dry functions, low noise of the vacuum cleaner, stable operation without shaking, and a long service life of the filter block, which meets the requirements of wide use of the vacuum cleaner, long service life of the filter block, and no need for frequent replacement.

[0005] The technical solution adopted by the present invention to solve its technical problems: This new type of wet and dry vacuum cleaner includes a housing. Inside the housing, a first circular ring plate is fixed. A first bearing is installed on the inner contour surface of the first circular ring plate. A first thrust bearing is installed on the top surface of the first circular ring plate. A rotating cylinder is installed at the inner ring of the first bearing. At the top end of the rotating cylinder, a placing plate placed on the first thrust bearing is fixed. A first ventilation hole is opened on the placing plate. Above the placing plate, a first support plate fixed to the housing is provided. A cylindrical body is fixed on the first support plate. A second circular ring plate that fits on the bottom surface of the placing plate is fixed to the bottom surface of the cylindrical body. A second support plate is fixed at the inner contour of the cylindrical body. A shaft rod is rotatably connected to the second support plate; The bottom of the rotating cylinder is in an "eight"-shaped cone and is provided with a group of second ventilation holes evenly distributed along the center of the rotating cylinder. A first filter block covering each second ventilation hole is installed on the bottom surface of the rotating cylinder. Three support circular plates are fixed on the shaft rod and are sequentially spaced from top to bottom. Each support circular plate is in an "eight" shape and is provided with a group of third ventilation holes evenly distributed along the center of the support circular plate. A second filter block covering each third ventilation hole is installed on the bottom surface of each support circular plate. The filter holes of the three second filter blocks increase sequentially from top to bottom. The filter holes of the first filter block are larger than the filter holes of the lowermost second filter block; A first driving member for driving the rotating cylinder to rotate clockwise is installed on the housing. A second driving member for driving the shaft rod to rotate counterclockwise is installed on the cylindrical body; A group of fourth ventilation holes evenly distributed around the center of the second support plate are opened on the second support plate. The first support plate is fixed with a high-power centrifugal fan communicated with each fourth ventilation hole. An air outlet for air outlet is opened on the housing. A suction pipe communicated with the cavity of the housing is installed on the housing. A suction cup is fixed at the end of the suction pipe. An opening and closing switch is installed on the housing.Here, the first annular plate, the first bearing, the first thrust bearing, the drum, the placing plate, the bottom of the drum in an "eight" shape, the second vent, the first filter block, and the first driving member function to enable the drum to rotate clockwise, thereby preventing dust, dirt, and water droplets from being adsorbed on the first filter block, and the dust, dirt, and water droplets can be thrown away by centrifugal force, which can greatly improve the long-term filtering effect of the first filter block; here, the first support plate, the cylindrical body, the second annular plate, the second support plate, the shaft rod, and each supporting circular plate are in an "eight" shape, the third vent, the second filter block, and the second driving member function to give each second filter block counterclockwise rotation, thereby not only being able to grade and filter the inhaled exhaust gas, the filtering effect will be better, and the centrifugal force method can be used to prevent dust and dirt from being attached to the second filter block, which can greatly improve the long-term filtering effect of each second filter block; here, the filter holes of the three second filter blocks increase from top to bottom, and the filter hole of the first filter block is larger than the filter hole of the second filter block at the bottom. The function of the holes is to filter the inhaled dust, exhaust gas and water droplets in stages, so as to achieve a better filtering effect, and to avoid the problem that a single filter block is easily blocked and the filtering effect is reduced, thereby greatly increasing the filtering efficiency and the filtering life of the filter block; the function of the high-power centrifugal fan here is to provide strong suction; the function of the air outlet here is to discharge the gas extracted by the high-power centrifugal fan; the function of the suction tube and the suction cup here is to drag the ground, so as to absorb and absorb the dust, dirt and water droplets on the ground; the function of the clockwise rotation of the drum and the counterclockwise rotation of the shaft here is not only to generate centrifugal force on the first filter block and each second filter block to avoid dust, dirt and water droplets from adhering to them, but also to make the vacuum cleaner more stable when working by offsetting the rotation force, avoiding the shaking problem of the vacuum cleaner caused by the rotation of a single drum or shaft, achieving the effect of killing two birds with one stone; the first filter block, the second filter block and the third filter block here use stainless steel filter or HEPA filter material.

[0006] Further improvement, the first driving member includes a large gear fixed on the shelf, the large gear has a through hole in the middle and is arranged coaxially with the drum, a group of first motors are fixed on the housing, and a small gear meshing with the large gear is fixed on the rotating shaft of each first motor. Here, the function of the large gear, the first motor, and the small gear is to drive the small gear to rotate through each first motor, thereby driving the large gear to rotate, and then driving the drum to rotate, so that the first filter block at the bottom of the drum can rotate clockwise.

[0007] For further improvement, the second driving member includes a worm gear fixed to the top end of the shaft rod. A group of worm shafts are rotatably connected to the cylindrical body and are evenly distributed along the center of the cylindrical body and are all meshed with the worm gear. A group of second motors for driving the rotation of each worm shaft are fixed on the cylindrical body. The functions of the worm gear, the worm shafts, and the second motors are to drive the shaft rod to rotate counterclockwise, thereby driving each supporting circular plate to rotate counterclockwise, and thus synchronously driving each second filter block to rotate counterclockwise.

[0008] For further improvement, a support pier is fixed to the bottom surface of the inner cavity of the rotating cylinder. A blind hole is formed in the support pier. A second bearing is installed on the contour surface of the blind hole, and a second thrust bearing is installed on the bottom surface of the blind hole. The bottom of the shaft rod is inserted into the inner ring of the second bearing and the bottom surface is placed on the top surface of the second thrust bearing. The functions of the support pier, the blind hole, the second bearing, and the second thrust bearing are to support the bottom surface of the shaft rod. And through the installation of the second bearing, the shaft rod is not only supported in place, but also has less frictional resistance when rotating, and each supporting circular plate runs more stably and rotates more labor-savingly.

[0009] For further improvement, the bottom surface of the housing is a concave conical surface. A waste outlet hole is formed in the bottom surface of the housing. A rubber plug is blocked at the waste outlet hole. The top surface of the rubber plug is an "eight"-shaped conical surface. A group of electric cylinders evenly distributed along the center of the housing are fixed on the outer contour surface of the bottom of the housing. A push rod is installed on the piston rod of each electric cylinder, and each push rod is fixed at the rubber plug. A waste discharge switch for driving the operation of the electric cylinders is installed on the housing. The function of the conical surface here is to enable the accumulated water and dirt to be discharged cleanly from the waste outlet hole according to the action of gravity. The functions of the waste outlet hole, the rubber plug, the electric cylinders, and the push rods here are to conveniently control the up and down movement of the rubber plug, so as to conveniently empty the waste storage pool at the bottom of the inner cavity of the housing (which contains the inhaled water, dust, and dirt).

[0010] For further improvement, an end cover is threadedly connected to the top end of the housing. A turning handle is fixed on the end cover. The rotating cylinder and the placing plate are fastened together by fasteners. The shaft rod includes an upper rod and a lower rod. A square jack is formed in the bottom surface of the upper rod. A square plug rod that is inserted and matched with the square jack is fixed at the top end of the lower rod. A self-lubricating layer is provided on the outer contour of each supporting circular plate. The functions of the end cover, the turning handle, the fasteners, the upper rod, the lower rod, the square jack, and the square plug rod are to enable the rotating cylinder and the supporting circular plates to be disassembled, so as to clean the dust and dirt on the first filter block and each second filter block, so that it is not necessary to replace the new first filter block and each second filter block, and the use cost is reduced without affecting the filtration efficiency. The function of the self-lubricating layer here is to enable the outer contour of the supporting circular plate to fit more closely with the inner contour wall of the rotating cylinder. When the rotating cylinder and the supporting circular plates run in opposite directions, they will be more stable, and it will not cause the waste gas with dust to flow out without passing through the filtration of the second filter block. The self-lubricating layer is made of tin bronze material.

[0011] Further improvement: A circle of bristles is fixed to the bottom surface of the suction cup. The function of the bristles here is to brush off the dirt adhering to the place and then suck it away, achieving a better cleaning purpose.

[0012] Further improvement: A partition is fixed inside the end cap and located below the air outlet. A jack for sleeving on the high-power centrifugal fan is opened on the partition. The functions of the partition and the jack here are to make the high-power centrifugal fan operate more stably and to block the inner cavity of the end cap, enabling the filtered air extracted by the high-power centrifugal fan to be quickly discharged from the air outlet.

[0013] Further improvement: A set of universal wheels is installed at the bottom of the housing. The function of the universal wheels here is to facilitate moving the vacuum cleaner, and it can be easily moved in various directions, thus facilitating vacuuming at various angles on the ground.

[0014] Further improvement: Sound-absorbing cotton is installed on the inner contour surface of the housing. The function of the sound-absorbing cotton here is to greatly reduce the noise generated by the vacuum cleaner during operation; here, the sound-absorbing cotton is made of polyester fiber sound-absorbing cotton with a density ≥ 30 kg / m³.

[0015] The beneficial effects of the present invention are as follows: 1). Through the first circular ring plate, the first bearing, the first thrust bearing, the rotating cylinder, the placing plate, the bottom of the rotating cylinder being in an "eight" shape, the second ventilation hole, the first filter block, and the first driving member, the rotating cylinder can rotate clockwise, thereby preventing dust, dirt, and water droplets from adhering to the first filter block. Through centrifugal force, the dust, dirt, and water droplets can be thrown away, greatly improving the long-term filtering effect of the first filter block; 2). Through the first support plate, the cylindrical body, the second circular ring plate, the second support plate, the shaft rod, each support circular plate being in an "eight" shape, the third ventilation hole, the second filter block, and the second driving member, the second filter blocks can be rotated counterclockwise, which can not only filter the inhaled waste gas in stages with better filtering effect, but also, by using the centrifugal force method, prevent dust and dirt from adhering to the second filter blocks, greatly improving the long-term filtering effect of each second filter block; 3). By increasing the filtering holes of the three second filter blocks sequentially from top to bottom, and the filtering holes of the first filter block being larger than those of the lowermost second filter block, the inhaled dust waste gas and water droplets can be filtered in stages, thereby achieving a better filtering effect and avoiding the problem that a single filter block is easily blocked and the filtering effect is reduced, thus greatly increasing the filtering efficiency and the filtering life of the filter block; 4). The rotating cylinder and the supporting circular plate can be disassembled through the end cap, the screwing handle, the fastener, the upper rod, the lower rod, the square jack and the square plug rod, so as to clean the dust and dirt on the first filter block and each second filter block, thus eliminating the need to replace the new first filter block and each second filter block, and reducing the use cost without affecting the filtration efficiency. 5). By means of the waste outlet hole, the rubber plug head, the electric cylinder and the push rod, the up-and-down movement of the rubber plug head can be conveniently controlled, so as to facilitate the emptying of the waste material pool (containing the inhaled water, dust and dirt) at the bottom of the inner cavity of the shell.

[0026] A group of universal wheels 23 are installed at the bottom of the housing 1.

[0027] A sound insulation cotton 24 is installed on the inner contour surface of the housing 1.

[0028] Working principle of the present invention: During use, press the opening and closing switch 25, so that the high-power centrifugal fan 6a operates, and each first motor 12-2 and each second motor 13-3 also operate synchronously, thereby driving the rotating cylinder 5 and the shaft rod 8 to rotate in the opposite direction, thereby driving the first filter block 9 and each second filter block 11 to rotate. At this time, the suction cup 16 can continuously suck the dirt, dust and water stains on the ground, and the adsorbed dirt is sucked into the cavity of the housing 1 through the suction pipe 15. When only dust is adsorbed, it can be filtered by the first filter block 9 and each second filter block 11 in stages, and large-particle dust and small-particle dust can be filtered out. Finally, the filtered air is discharged through the air outlet 1-1. Here, the first filter block 9 and each second filter block 11 adhere to the bottom end of the rotating cylinder 5 and adhere to the supporting circular plate 10 and are in a "V" shape. Therefore, under the action of the centrifugal force in the rotating state, the dirt is thrown and separated towards the edge by the centrifugal force and will not adhere to the first filter block 9 and each second filter block 11 in large quantities. Therefore, the first filter block 9 and each second filter block 11 can maintain high filtration performance for a long time without frequent maintenance; when adsorbing dirt with water stains, since the water stains are relatively heavy, part of the water stains fall to the waste storage cavity of the housing 1 by gravity, part of the water stains are lighter and float with the air flow and are filtered by the first filter block 11, and a small part of the water vapor is completely removed after being filtered by each second filter block 11. At this time, the filtered filter block has a certain humidity. At this time, under the strong centrifugal force of the first filter block 9 and each second filter block 11 rotating at high speed, the water stains will accumulate and drip towards the edges of the first filter block 11 and each second filter block 9, so as to ensure that the filter surfaces of the first filter block 9 and each second filter block 11 always remain dry and clean, which will not affect the filtration efficiency and there is no need to often disassemble and maintain. After all, the product has a service life. When it needs to be cleaned or the filter block needs to be replaced after long-term use, only need to disassemble the end cover 20 and disassemble the rotating cylinder 5 and the shaft rod 20 to clean or replace the first filter block 9 and each second filter block 11, and the use cost is greatly reduced, which can save a large amount of money for the user; when the waste storage cavity at the bottom of the inner cavity of the housing 1 is full of dirt, press the waste discharge switch 26, so that each electric cylinder 18 drives the rubber plug 17 to move downward through the push rod 19, and the dirt is discharged through the waste outlet 1-3 to the designated position. The present invention can be used for both dry and wet cleaning, adopts multi-stage and multi-layer filtration, has good filtration effect, low noise of the vacuum cleaner, stable operation without shaking, and long service life of the filter block, and is worthy of popularization and application.
