[0002] With social development and the advancement of science and technology, people's material and cultural living standards have greatly improved, and vacuum cleaners, as commonly used household appliances, are becoming increasingly popular in every home. Vacuum cleaners can be classified into upright, canister, and portable types according to their structure. The working principle of a vacuum cleaner is that an electric motor drives the blades to rotate at high speed, creating negative air pressure within a sealed casing to suck up dust and debris.

[0003] While the large wheels at the side air outlet of currently used vacuum cleaners are relatively easy to assemble and fix to the vacuum cleaner body, they require the sequential installation of multiple parts, which is prone to errors in the order of installation, leading to failure to install or forgetting to install certain parts. For example, a vacuum cleaner side air outlet large wheel fixing device (authorization announcement number CN103156552B) also has similar problems. Therefore, a new type of vacuum cleaner side air outlet large wheel fixing device is needed. Summary of the Invention

[0004] The purpose of this invention is to provide a fixing device for the large wheel of the side air outlet of a vacuum cleaner, so as to solve the problems mentioned in the background art.

[0006] A suction device is connected to the top of the side wall of the water tank away from the suction pipe, and the suction device is fixedly connected to the inner cavity side wall of the housing. A fan is fixedly installed on the side wall of the housing away from the suction pipe, and the fan is enclosed in the suction device. A retainer is welded to the outer side wall of the housing away from the suction pipe, and the retainer is coaxial with the fan. A large wheel is engaged with the retainer, and a knob for easy rotation is provided on the large wheel.

[0007] Preferably, one horizontal end of the suction tube passes through the shell and the water tank, and this end is threaded. The inner cavity of the aerator is welded with a first aerator plate and a second aerator plate from bottom to top, and both the first aerator plate and the second aerator plate are evenly provided with several through holes.

[0008] Preferably, the top of the top plate is wedge-shaped and a rubber ring is bonded to the top of the top plate, and the top of the housing is provided with a through groove adapted to the top of the top plate.

[0009] Preferably, the inner cavity of the suction device is welded with a clip, the clip is inserted with a filter plate for filtering dust, and the suction device and the housing are provided with through holes adapted to the filter plate.

[0010] Preferably, the outer side wall of the housing is symmetrically welded with two clamping plates with pressure plates on top, and the clamping plates are clamped to the edge of the filter plate. The end of the filter plate away from the housing is welded with a protrusion that facilitates extraction.

[0011] Preferably, the card holder has a groove for mounting the large wheel, and the side wall of the groove has several slots. Several second springs are uniformly welded to the bottom of the groove of the card holder, and all the second springs are fixedly connected to a ring.

[0014] Compared with the prior art, the technical effects and advantages of the present invention are as follows:

[0015] The vacuum cleaner features a side exhaust wheel fixing device. During use, water is added to the water tank through the inlet pipe, submerging the aerator. The suction pipe draws in dusty air, which is then expelled into the aerator. The dusty air passes through the first and second aerator plates and the through holes on the aerator, turning into small bubbles that mix the dust with the water, thus performing preliminary air purification. After use, the wastewater is discharged through the drain pipe. When the aerator becomes clogged, the wrench is turned to loosen the pressure block from pressing the top plate, allowing the aerator to be pulled out for cleaning via the handle on the top plate. The aerator is designed to facilitate the mixing of dust and water, improving purification efficiency.

First, drain the water from the water tank, then reverse the fan to blow the dust from the vacuum cleaner into the water tank, and some of it will be discharged through the suction pipe. Next, press the pressure plate on the clamping plate, and the clamping plate will no longer hold the filter plate in place. The filter plate can then be pulled out and replaced through the protrusion. This easy filter replacement reduces maintenance time.

[0017] The large wheel fixing device for the side air outlet of this vacuum cleaner is designed to be easy to install. To install the large wheel, align the locking block on the large wheel with the slot and insert it into the mounting bracket. Then, press the large wheel firmly while simultaneously rotating it using the knob until it can no longer rotate. Release the large wheel and the knob; the second spring will push the ring outwards to hold the large wheel in place, thus locking the locking block in the slot. Once the large wheel is installed, only one large wheel is needed to assemble and fix it to the vacuum cleaner body, making installation more convenient and less prone to errors.

[0032] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that the invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid obscuring the invention.

[0033] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0034] To facilitate the fixed installation of the large wheels at the side exhaust vent of the vacuum cleaner, such as Figures 1 to 11 The illustrated vacuum cleaner side exhaust wheel fixing device requires only a single wheel 24 to be mounted and fixed to the vacuum cleaner body, making installation more convenient and less prone to errors. It includes a housing 1, with a water tank 2 fixedly installed inside the housing 1. A water inlet pipe 27 is welded to the top of the water tank 2 and threaded through the housing 1 with a first sealing cap 28. A drain pipe 29 is welded to the side wall of the water tank 2 and threaded through the housing 1 with a second sealing cap 30. The inner diameter of the drain pipe 29 is tangent to the bottom surface of the inner cavity of the water tank 2. A suction pipe 3 for sucking up dust is welded inside the water tank 2, with one end of the suction pipe 3 opening horizontally. The suction pipe 3 passes through the housing 1 and the water tank 2, and is threaded at one end. This end can be threaded to connect to a vacuum cleaner hose with a brush head. The opening of the suction pipe 3 facing upward covers the aerator 4. The top of the aerator 4 is evenly provided with several through holes. The inner cavity of the aerator 4 is welded with a first aerator plate 5 and a second aerator plate 6 from bottom to top. Both the first aerator plate 5 and the second aerator plate 6 are evenly provided with several through holes. The through holes on the first aerator plate 5, the second aerator plate 6 and the aerator 4 decrease in size in sequence. The four corners of the upper surface of the aerator 4 are welded with support columns 7. The tops of the four support columns 7 are fixedly connected to a top plate 8. A handle is welded to the top of the top plate 8.

[0035] The top of the top plate 8 is wedge-shaped, and a rubber ring 9 is bonded to the top of the top plate 8. The top of the housing 1 is provided with a through groove that fits the top of the top plate 8. The rubber ring 9 is used to enhance the sealing between the top of the top plate 8 and the through groove at the top of the housing 1. A rotating shaft 10 is fixedly installed on the housing 1. A wrench 12 is rotatably sleeved on the rotating shaft 10. A pressure block 13 is welded to the side wall of the wrench 12, and the bottom surface of the pressure block 13 contacts the top plate 8. A first spring 11 is sleeved on the rotating shaft 10, and the first spring 11 is located between the housing 1 and the wrench 12.

[0036] During use, water is added to the water tank 2 through the inlet pipe 27, submerging the aerator 4. The suction pipe 3 draws in air containing dust and discharges it into the aerator 4. The air containing dust passes through the first aerator plate 5, the second aerator plate 6, and the through holes on the aerator 4, turning into small bubbles. This mixes the dust in the air with the water, thus purifying the air initially. After use, the wastewater is discharged through the drain pipe 29. When the aerator 4 becomes clogged, the wrench 12 is turned so that the pressure block 13 no longer presses against the top plate 8. The aerator 4 can then be pulled out for cleaning through the handle on the top of the top plate 8.

[0037] A suction device 14 is connected to the top of the side wall of the water tank 2 away from the suction pipe 3, and the suction device 14 is fixedly connected to the inner cavity side wall of the housing 1. A bracket 15 is welded to the inner cavity of the suction device 14, and a filter plate 16 for filtering dust is inserted into the bracket 15. Through holes for matching the filter plate 16 are opened on the suction device 14 and the housing 1. Two clamping plates 19 with pressure plates on the top are symmetrically welded to the outer side wall of the housing 1, and the clamping plates 19 are clamped to the edge of the filter plate 16. A protrusion 17 for easy removal is welded to the end of the filter plate 16 away from the housing 1.

[0038] When replacing filter plate 16, first drain the water in water tank 2, then turn fan 18 back to blow the dust from suction fan 14 into water tank 2, and some of it will be discharged through suction pipe 3. Then press the pressure plate on clamp plate 19, and clamp plate 19 will no longer hold filter plate 16. Pull out filter plate 16 through protrusion 17 for replacement.

[0039] A fan 18 is fixedly installed on the side wall of the housing 1 away from the suction pipe 3, and the fan 18 is enclosed in the suction unit 14. A retainer 20 is welded to the outer side wall of the housing 1 away from the suction pipe 3, and the retainer 20 is coaxial with the fan 18. A large wheel 24 is engaged with the retainer 20, and a knob 26 for easy rotation is provided on the large wheel 24. The retainer 20 has a groove for mounting the large wheel 24, and several slots 21 are provided on the side wall of the groove. Several second springs 22 are evenly welded to the bottom of the groove of the retainer 20, and all the second springs 22 are fixedly connected to a ring 23. Several locking blocks 25 that are adapted to the slots 21 are welded to one end of the large wheel 24 that engages with the retainer 20. Several through slots for air outlet are evenly provided on the large wheel 24.

[0040] When installing the large wheel 24, align the locking block 25 on the large wheel 24 with the slot 21 and insert it into the slot 20. Then press the large wheel 24 firmly while rotating the large wheel 24 with the knob 26 until it can no longer rotate. Then release the large wheel 24 and the knob 26. The second spring 22 pushes the ring 23 outward to hold the large wheel 24, so that the locking block 25 is locked in the slot 21. The installation of the large wheel 24 is complete.

[0041] Working principle

[0042] The vacuum cleaner features a side exhaust wheel fixing device. During use, water is added to the water tank 2 through the inlet pipe 27, submerging the aerator 4. The suction pipe 3 draws in dusty air, which is then expelled into the aerator 4. The dusty air passes through the first aerator plate 5, the second aerator plate 6, and the through-holes in the aerator 4, turning into small bubbles. This mixes the dust with the water, providing initial air purification. After use, wastewater is discharged through the drain pipe 29. When the aerator 4 becomes clogged, the wrench 12 is turned so that the pressure block 13 no longer presses against the top plate 8. The aerator 4 can then be pulled out for cleaning using the handle on top of the top plate 8. When replacing the filter plate 16, the water tank should be drained first. The water in tank 2 is blown back by fan 18, causing the dust from suction device 14 to be blown into water tank 2, and some of it is discharged through suction pipe 3. Then, press the pressure plate on the clamping plate 19, and the clamping plate 19 will no longer hold the filter plate 16. The filter plate 16 can be pulled out and replaced by the protrusion 17. When installing the large wheel 24, align the clamping block 25 on the large wheel 24 with the slot 21 and insert it into the clamping seat 20. Then press the large wheel 24 firmly and rotate the large wheel 24 with knob 26 until it can no longer rotate. Then release the large wheel 24 and knob 26. The second spring 22 pushes the ring 23 outward to hold the large wheel 24, so that the clamping block 25 is locked in the slot 21. The installation of the large wheel 24 is complete.
