Description

Technical Field

[0001] This application relates to the field of wet vacuum cleaner technology, and in particular to a wet vacuum cleaner. Background Technology

[0002] The cutting equipment needed for the sealing strip production line is used to cut sealing strips that contain both metal and rubber. Waste collection is generally done using industrial dry vacuum cleaners. During use, high-temperature debris generated when sawing the steel strips of the products can ignite rubber debris accumulated on the vacuum cleaner's filter screen, causing a fire and significant losses. If water cooling is used, the debris and water will be sucked into the vacuum cleaner together, making it difficult to solve the problem of continuous production. Therefore, there is an urgent need for a small wet vacuum cleaner to solve this problem.

[0003] However, existing wet vacuum cleaners still have the following drawbacks: general vacuum cleaners may require additional water pumps and motors to drive water circulation and suction functions, which may increase overall energy consumption; general vacuum cleaners may not be suitable for all environments, especially those that need to avoid moisture or dampness, such as cleaning electronic devices or certain chemicals; although polyester fiber filter cartridges have a long service life and good durability, they still need to be replaced after long-term use, which may require users to perform regular maintenance and replacement, increasing the cost of use; and general wet vacuum cleaners are still susceptible to corrosion or wear in extreme environments, affecting their service life. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, this application provides a wet vacuum cleaner.

[0005] The wet vacuum cleaner provided in this application adopts the following technical solution:

[0006] A wet vacuum cleaner includes a mounting frame and a filter mechanism and a water tank and pump device located on the mounting frame. The filter mechanism includes a filter cartridge and a cyclone separator. The inlet pipe of the cyclone separator is connected to a suction pipe. The top of the cyclone separator is connected to the filter cartridge, and the bottom is connected to the water tank and pump device. A high-pressure fan is connected to the end of the filter cartridge away from the cyclone separator. The water tank and pump device includes a housing located at the bottom of the cyclone separator. A water pump is connected to the side of the housing via a pipe, and a water outlet valve is installed at the bottom of the housing. A handle is also installed on one side of the mounting frame located on the inlet pipe of the cyclone separator, and wheels are installed at the bottom of the mounting frame.

[0007] By adopting the above technical solution, the high-pressure blower is started, and the negative pressure port of the high-pressure blower is connected to the filter mechanism. The suction pipe connected to the inlet pipe sucks in outside air along with dust and debris. In the cyclone separator, centrifugal force is used to separate larger dust and debris particles by gravity, and they fall into the lower chamber. The air carrying fine particles and dust rises and enters the filter cartridge for further filtration. The filtered clean air is then discharged by the high-pressure blower. At the same time, water is introduced into the chamber through an external water source via a water pump, and the water outlet valve at the bottom of the chamber can discharge the water inside the chamber. The water in the chamber can be circulated and replaced by a pipe connecting the water pump and the water outlet valve at the bottom. The water tank is placed below the cyclone separator mechanism, which can cool the impurities entering the filter mechanism and prevent water from entering the vacuum cleaner's filter screen. The user controls the vacuum cleaner to move by gripping the handle, and the wheels at the bottom of the mounting frame facilitate flexible movement on the ground.

[0008] Preferably, the cyclone separator includes a cylinder, with an inlet pipe located on the top side of the cylinder and distributed along the tangential direction of the side of the cylinder, wherein a diffuser is provided at the connection between the inlet pipe and the cylinder.

[0009] Preferably, the top center of the cylinder is connected to the bottom of the filter cartridge via a dust collection pipe, wherein the filter cartridge includes a sealing frame and a filter cartridge inside the sealing frame, and a negative pressure pipe joint at one end of the filter cartridge penetrates the sealing frame.

[0010] Preferably, the bottom of the sealing frame adopts a conical base plate, wherein the center of the bottom of the conical base plate is connected to the top of the dust collection pipe, and a sealing ring is provided at the connection.

[0011] Preferably, a cleaning scraper is also installed inside the sealing frame, wherein the cleaning scraper is attached to the bottom of the filter cylinder, and the filter cylinder is rotatably installed inside the sealing frame.

[0012] Preferably, the filter cylinder includes circular end plates at both ends and an annular filter screen between the end plates. The center of the circular end plate at one end is rotatably connected to the negative pressure pipeline through a sealed bearing, and the center of the circular end plate at the other end has a rotating handle. The rotating handle passes through the sealed frame and is connected to the sealed frame through a sealed bearing.

[0013] By adopting the above technical solution, the high-pressure blower generates suction upon startup. Gas containing impurities enters through the dust collection pipe from the tangential inlet pipe on the top side of the cyclone separator cylinder. Due to the expanding pipe at the connection between the inlet pipe and the cylinder, the change in airflow velocity causes large dust particles to initially settle. The gas rotates at high speed inside the cylinder, using centrifugal force to further separate more particles. The separated dust falls to the bottom of the cylinder, while the gas carrying fine particles enters the filter cartridge through the dust collection pipe at the center of the top of the cylinder. Inside the filter cartridge, the gas enters the filter body within the sealed frame, where a ring-shaped filter screen performs fine filtration. The filtered clean air is then drawn from the filter cartridge through the high-pressure blower's inlet pipe via a negative pressure pipe joint. The high-pressure blower is connected to the outside through an exhaust pipe to prevent excessive pressure inside the blower. As filtration proceeds, dust will accumulate on the outer surface of the filter cartridge. At this point, the machine can be stopped, and the filter cartridge can be rotated within the sealed frame by turning the handle. The dust scraper attached to the bottom of the filter cartridge will scrape off the dust, which will then fall through the conical bottom plate and dust collection pipe into the water tank and pump unit for collection, achieving continuous and efficient filtration and dust removal.

[0014] Preferably, the high-pressure blower is located in the mounting frame on the side of the cyclone separator. The high-pressure blower includes a blower body and an inlet pipe and an outlet pipe connected to the blower body. The side of the mounting frame is provided with heat dissipation holes.

[0015] By adopting the above technical solution, the high-pressure blower is started, and the blower body begins to operate, creating negative pressure at the air inlet pipe, drawing in the air that has undergone preliminary dust removal and filtration by the cyclone separator. After being pressurized within the blower body, the air is discharged from the outlet pipe. During the operation of the high-pressure blower, the heat generated by the blower body is dissipated in a timely manner through the heat dissipation holes on the side of the mounting frame, ensuring that the blower body operates stably at a suitable temperature, continuously providing power to the dust collection system, ensuring the efficient operation of the entire vacuum cleaner, and achieving effective collection and filtration of dust and debris.

[0016] Preferably, the housing includes a water tank at the bottom and a filter drawer at the top, wherein the filter drawer is located at the bottom of the cyclone separator and is sealed to the housing.

[0017] By adopting the above technical solution, during the operation of the wet vacuum cleaner, dust, debris, and some fine particles carried in the airflow, separated by the cyclone separator, fall into the filter drawer located at the bottom of the cyclone separator. The filter drawer intercepts and filters dust and debris, preventing them from directly entering the water tank and causing blockage. After passing through the filter drawer, the airflow enters the water tank at the bottom of the unit, where the residual dust and impurities are further purified through the adsorption and sedimentation effects of the water. The purified air continues to enter the subsequent filtration mechanism, and the filter drawer can be disassembled and cleaned periodically. Wastewater in the water tank can also be discharged and replaced through the outlet valve, thus ensuring that the water tank and water pump device can stably perform their filtration and storage functions over a long period of time.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application uses a multi-stage filtration mechanism that combines a cyclone separator with a filter cartridge. The inlet pipe is distributed along the tangent of the cylinder and the design of the diffuser allows the dust-laden gas to make full use of centrifugal force in the cyclone separator to initially separate large dust particles. Then, the gas is finely filtered by the filter cartridge, which effectively reduces the amount of dust entering the housing and avoids the risk of fire caused by the accumulation of rubber debris being ignited by high-temperature metal debris.

[0020] 2. This application, through the design of a filter drawer and a water tank in the housing, first intercepts dust and debris through the filter drawer, and then uses the water tank to further purify the air. This not only solves the problem of continuous production caused by the mixing of debris and water, but also reduces the clogging of the filter cartridge, extends the service life of the filter cartridge, and reduces maintenance costs.

[0021] 3. This application uses a high-pressure blower installed in the mounting frame on the side of the cyclone separator, and the mounting frame is equipped with heat dissipation holes to ensure stable operation of the blower and provide continuous power for dust collection. At the same time, no additional complex drive device is required, reducing overall energy consumption. The design of the dust cleaning scraper and the rotatable filter cartridge can clean the dust on the surface of the filter cartridge in time, further improving filtration efficiency and reducing maintenance frequency.

[0022] 4. This application facilitates movement through the handles and wheels on the mounting frame, making it suitable for various scenarios such as sealing strip production lines. The optimized design of the overall structure enhances the adaptability and durability of the equipment in complex environments, reduces damage caused by corrosion and wear, improves the service life of the equipment, reduces operating costs, and meets the safety, efficiency, and continuity requirements of sealing strip production lines for waste collection equipment.

[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0028] This application discloses a wet vacuum cleaner.

[0029] Reference Figure 1 , Figure 2 and Figure 3A wet vacuum cleaner includes a mounting frame 1, a filter mechanism 2, and a water tank and pump device 3 located on the mounting frame 1. The filter mechanism 2 includes a filter cartridge 21 and a cyclone separator 22. The inlet pipe 23 of the cyclone separator 22 is connected to a suction pipe. The top of the cyclone separator 22 is connected to the filter cartridge 21, and the bottom is connected to the water tank and pump device 3. A high-pressure blower 4 is connected to the end of the filter cartridge 21 away from the cyclone separator 22. The water tank and pump device 3 includes a housing 31 located at the bottom of the cyclone separator 22. A water pump 32 is connected to the side of the housing 31 through a pipe. A water outlet valve 33 is installed at the bottom of the housing 31. A handle 11 is also installed on the side of the mounting frame 1 located on the inlet pipe 23 of the cyclone separator 22, and wheels 12 are installed at the bottom of the mounting frame 1. The high-pressure blower 4 is started. The negative pressure port of the high-pressure blower 4 is connected to the filter mechanism 2. The suction pipe connected to the inlet pipe 23 draws in outside air along with dust and debris. In the cyclone separator 22, centrifugal force causes larger dust and debris particles to separate under gravity and fall into the lower housing 31, while the air carrying fine particles and dust rises into the filter cartridge 21 for further filtration. The filtered clean air is then discharged by the high-pressure blower 4. At the same time, water is introduced into the housing 31 through the water pump 32. The water outlet valve 33 at the bottom of the housing 31 can discharge the water inside the housing 31. The water pump 32 and the water outlet valve 33 at the bottom can be connected to an external water source to achieve water circulation and replacement in the housing 31. Placing the water tank below the cyclone separator can cool the impurities entering the filter mechanism 2 and prevent water from entering the vacuum cleaner's filter screen. The user controls the vacuum cleaner to move using the handle 11, and the wheels 12 at the bottom of the mounting frame 1 facilitate its flexible movement on the ground.

[0030] Reference Figure 1 , Figure 2 and Figure 3The cyclone separator 22 includes a cylindrical body 221. An inlet pipe 23 is located on the top side of the cylindrical body 221 and is distributed along the tangential direction of the side of the cylindrical body 221. A diffuser pipe 231 is provided at the connection between the inlet pipe 23 and the cylindrical body 221. The top center of the cylindrical body 221 is connected to the bottom of the filter cartridge 21 via a dust collection pipe 222. The filter cartridge 21 includes a sealing frame 211 and a filter cartridge 212 inside the sealing frame 211. A negative pressure pipe 213 connector at one end of the filter cartridge 212 passes through the sealing frame 211. The bottom of the sealing frame 211 adopts a conical base plate 2111, the bottom center of which connects to the top of the dust collection pipe 222, and a sealing ring is provided at the connection. A cleaning scraper 2112 is also installed inside the sealing frame 211, with the cleaning scraper 2112 fitting against the bottom of the filter cartridge 212. The filter cartridge 212 is rotatably installed inside the sealing frame 211. The filter cartridge 212 includes circular end plates 2121 at both ends and an annular filter screen 2122 between the end plates. The center of one circular end plate 2121 is rotatably connected to the negative pressure pipe 213 via a sealed bearing 2123. The center of the other circular end plate 2121 has a rotating handle 2124, which passes through the sealed frame 211 and is connected to the sealed frame 211 via the sealed bearing 2123. The high-pressure blower 4 starts to generate suction. The gas containing impurities enters through the dust collection pipe from the tangential inlet pipe 23 on the top side of the cyclone separator 22 cartridge 221. Due to the expansion pipe 231 at the connection between the inlet pipe 23 and the cartridge 221, the change in airflow velocity causes large dust particles to initially settle. The gas rotates at high speed inside the cartridge 221, and centrifugal force is used to further separate more particles. The separated dust falls to the bottom of the cartridge 221, while the gas carrying fine particles enters the filter cartridge 21 through the dust collection pipe 222 at the center of the top of the cartridge 221. In the filter cartridge 21, gas enters the filter cartridge 212 inside the sealed frame 211. The annular filter screen 2122 performs fine filtration on the gas. The filtered clean air is then drawn out of the filter cartridge 21 through the negative pressure pipe 213 connector and the intake pipe 42 of the high-pressure blower 4. The high-pressure blower 4 is connected to the outside through the exhaust pipe to prevent excessive pressure inside the blower 4. As filtration proceeds, dust will adhere to the outer surface of the filter cartridge 212. At this time, the machine can be stopped, and the filter cartridge 212 can be rotated inside the sealed frame 211 by turning the rotating handle 2124. The cleaning scraper 2112 attached to the bottom of the filter cartridge 212 will scrape off the adhered dust, which will fall into the housing 31 of the water tank pump device 3 through the conical bottom plate 2111 and the dust collection pipe 222 for collection, achieving continuous and efficient filtration and dust removal.

[0031] Reference Figure 1 , Figure 2 and Figure 3The high-pressure blower 4 is located within the mounting frame 13 on the side of the cyclone separator 22. The high-pressure blower 4 includes a blower body 41 and an inlet pipe 42 and an outlet pipe 43 connected to the blower body 41. The mounting frame 13 has ventilation holes 14 on its side. When the high-pressure blower 4 is started, the blower body 41 begins to operate, creating a negative pressure at the inlet pipe 42, drawing in the air that has undergone preliminary dust removal and filtration by the cyclone separator 22. After being pressurized within the blower body 41, the air is discharged from the outlet pipe 43. During the operation of the high-pressure blower 4, the heat generated by the blower body 41 is dissipated promptly through the ventilation holes 14 on the side of the mounting frame 13, ensuring that the blower body 41 operates stably at a suitable temperature, continuously providing power to the dust collection system, ensuring the efficient operation of the entire vacuum cleaner, and achieving effective collection and filtration of dust and debris.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The housing 31 includes a water tank 311 at the bottom and a filter drawer 312 at the top. The filter drawer 312 is located at the bottom of the cyclone separator 22 and is sealed to the housing 31. During operation of the wet vacuum cleaner, dust, debris, and some fine particles carried by the airflow, separated by the cyclone separator 22, fall into the filter drawer 312 at the bottom of the cyclone separator 22. The filter drawer 312 intercepts and filters dust and debris, preventing them from directly entering the water tank 311 and causing blockage. After passing through the filter drawer 312, the airflow enters the water tank 311 at the bottom of the housing 31, where the water's adsorption and sedimentation further purifies any remaining dust and impurities. The purified air continues to enter the subsequent filtration mechanism 2. The filter drawer 312 can be periodically disassembled for cleaning, and the wastewater in the water tank 311 can be discharged and replaced through the outlet valve 33, thus ensuring the long-term stable operation of the water tank and pump device 3 in its filtration and storage functions.

[0033] Working Principle: When the wet vacuum cleaner is working, the high-pressure fan 4 is activated. The fan body 41 generates suction through the air intake pipe 42. Dust-laden gas from the outside enters through the suction pipe from the inlet pipe 23, which is tangentially distributed on the top side of the cyclone separator 22 cylinder 221. The diffuser 231 at the connection between the inlet pipe 23 and the cylinder 221 changes the airflow velocity, causing large dust particles to initially settle. The gas rotates at high speed inside the cylinder 221, further separating the particles using centrifugal force. The separated dust falls to the bottom of the cylinder 221, while the gas carrying fine particles enters the filter cartridge 21 through the dust collection pipe 222 at the top center of the cylinder 221. Inside the sealed frame 211 of the filter cartridge 21, the annular filter screen 2122 performs fine filtration of the gas. The filtered clean air is then passed through the negative pressure pipe 213 connector and is then... The air compressor 4 discharges air through the outlet pipe 43. At the same time, turning the handle 2124 can drive the filter cylinder 212 to rotate inside the sealed frame 211. The dust scraper 2112 scrapes off the dust attached to the outer surface of the filter cylinder 212, which falls into the housing 31 through the conical bottom plate 2111 and the dust collection pipe 222. The filter drawer 312 at the top of the housing 31 intercepts dust and debris. The airflow passing through the filter drawer 312 enters the bottom water tank 311, where it is further purified through water adsorption and sedimentation. The purified air continues to participate in subsequent circulation. The water pump 32 connected to the side of the housing 31 supplies water to the water tank 311, introducing clean water into the water tank 311. The water outlet valve 33 at the bottom facilitates the discharge of wastewater. The user operates the vacuum cleaner through the handle 11, and the wheels 12 at the bottom of the mounting frame 1 assist it in moving flexibly on the ground.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
