DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1:

[0038] This embodiment provides a water circulation foam cleaning device, which is used to recycle water and mix it with a foaming agent to generate foam. The foam is used to clean equipment, thereby achieving the effect of solving the problem of high water consumption and low cleaning efficiency of existing cleaning devices when cleaning large equipment.

[0039] refer to Figure 1 The foam cleaning device includes a DC motor 2, a housing 3, a composite fan 4, a sealing plate 5 and a cleaning roller brush 6.

[0040] Among them, the inside of the shell 3 is provided with a recovery pool area and a cleaning area, and an air inlet 34 connected to the recovery pool area is opened. The cleaning area is connected to the air inlet 34 through multiple foam outlet holes 31, and is connected to the recovery pool area through multiple water inlet holes 32. When cleaning the equipment, the foaming agent placed outside the shell 3 is manually flowed into the recovery pool area through the air inlet 34. The foaming agent can be quantitatively discharged through a device such as a liquid pump, so as to achieve the function of accurately controlling the amount of foaming. In order to produce the predetermined required foam, a plurality of foaming air guide holes 33 are opened on the shell 3. The plurality of foaming air guide holes 33 are all contained in the recovery pool area.

[0041] The composite fan 4 is housed in the recovery pool area and can rotate relative to the housing 3. Figure 2 The composite fan 4 includes a centrifugal fan blade 41 and a paddle 42, which satisfies the purpose of fully mixing the liquid and the gas. In this embodiment, the size and shape of the paddle 42 and the centrifugal fan blade 41 can be customized to a specific ratio to achieve an ideal compression ratio of air and liquid. The centrifugal fan blade 41 is annular. The paddle 42 is installed inside the centrifugal fan blade 41. When the composite fan 4 rotates, the paddle 42 can efficiently blow air to the center of the composite fan 4. At the same time, when the centrifugal fan blade 41 contacts water, the water is thrown away to the surroundings by centrifugal force. When the centrifugal fan blade 41 is completely immersed in water, the paddle 42 can still push the air to the center of the centrifugal fan blade 41, thereby completing the mixing of the liquid and the gas. In addition, during the rotation of the composite fan 4, the centrifugal fan blade 41 squeezes the mixture again through the bubble guide hole 33 to produce countless tiny bubbles, thereby producing the predetermined required foam. The design of the composite fan 4 adopts a method of combining two fans together to achieve the function of fully mixing gas and liquid.

[0042] The sealing plate 5 is integrally formed with the housing 3 and forms a recovery pool area with the housing 3. In this embodiment, a groove can also be provided on the housing 3. The sealing plate 5 is detachably mounted on the housing 3 and forms a recovery pool area with the groove.

[0043] The cleaning roller brush 6 is rotatably installed in the cleaning area, and when it rotates, it draws water into the water inlet hole 32 to flow into the recovery pool area. A section of the cleaning roller brush 6 is exposed to the outside of the shell 3, and is respectively arranged on opposite sides of the shell 3 with the air inlet hole 34. In this way, the cleaning roller brush 6 can contact the surface of the equipment to clean the equipment. When cleaning the equipment, the composite fan 4 rotates. When the composite fan 4 rotates, it stirs and mixes the water and foaming agent located in the recovery pool area to generate foam. The foam flows to the cleaning roller brush 6 through the foam outlet hole 31 to clean the equipment. In this embodiment, the cleaning roller brush 6 can be driven by a power device such as a rotating motor to rotate counterclockwise to draw the water used for flushing into the recovery pool area. The rotating motor is electrically connected to an external power supply.

[0044] The DC motor 2 is fixed to the outer wall of one end of the shell 3 near the cleaning roller brush 6, and the output shaft extends into the recovery pool area and is fixedly connected to the composite fan 4. Specifically, the DC motor 2 is fixed to the outer wall of one end of the shell 3 near the cleaning roller brush 6 through a motor base 35. The motor base 35 is integrally formed with the shell 3. In this embodiment, an electronic speed regulator can be added to set the rotation speed of the DC motor 2 to a specific speed to achieve the function of accurately controlling the amount of foaming. The DC motor 2 and the electronic speed regulator are both electrically connected to an external power supply. All parts in this case can be fixed or installed by snaps, screws, adhesives, threads and other processes according to structural requirements.

[0045] In this embodiment, when the equipment is flushed with water, the foam cleaning device contacts the surface of the equipment. At this time, the driving device drives the composite fan 4 to rotate. The composite fan 4 rotates to roll the flushing water back into the water inlet hole 32, and further flows into the recovery pool area through the water inlet hole 32 as a water supply source for the foam agent, so as to achieve the effect of making full use of water resources. At the same time, the foam agent flows into the recovery pool area through the air inlet hole 34. Then, the DC motor 2 drives the composite fan 4 to rotate and stir the water and the foam agent to produce foam. The foam is evenly discharged to the cleaning roller brush 6 through the foam outlet hole 31. Then, the cleaning roller brush 6 rotates to wash the foam and the surface stains of the equipment to complete an efficient cleaning operation.

[0046] Embodiment 2:

[0047] refer to Figure 3-5 In this embodiment, based on the first embodiment, a cleaning device is added to the foam cleaning device to achieve the effect of cleaning and recycling at the same time.

[0048] The cleaning device comprises a fixing pipe 13 , a flushing base 1 and a cleaning nozzle 12 .

[0049] Among them, the fixed pipe fitting 13 is fixed to the outer wall of one end of the housing 3 close to the DC motor 2. In this embodiment, the fixed pipe fitting 13 can be fixed to the outer wall of the housing 3 by at least one flushing pipe fixing plate 36. In this embodiment, the number of flushing pipe fixing plates 36 can be two. The two flushing pipe fixing plates 36 are symmetrical about the output axis of the DC motor 2. The specific installation method is: one end of each flushing pipe fixing plate 36 is installed on the outer wall of one end of the housing 3 close to the DC motor 2, and the other end of each flushing pipe fixing plate 36 is fixed to the fixed pipe fitting 13.

[0050] The number of flushing bases 1 is at least one. In the present embodiment, the number of flushing bases 1 is two. Each flushing base 1 is fixedly sleeved on a fixed pipe 13. There is at least one cleaning nozzle 12, and the number corresponds to the number of at least one flushing base 1, or it may be two. Each cleaning nozzle 12 is fixed on each flushing base 1, and points to the cleaning roller brush 6. Each cleaning nozzle 12 is a fan-shaped nozzle, and the spray channel of this fan-shaped nozzle is large and smooth, which reduces the blockage phenomenon. In the present embodiment, water is connected to the cleaning nozzle 12 through a water pipe so that the cleaning nozzle 12 sprays water to achieve the purpose of flushing. During the cleaning process, the foam cleaning device in the present embodiment moves from left to right, and the left side should be kept horizontal or upward so that the water sprayed from the cleaning nozzle 12 can all fall on the surface of the equipment. That is, the cleaning nozzle 12 should be kept horizontal or located above the shell 3.

[0051] In this embodiment, the cleaning roller brush 6 rotates to allow the foam to dissolve the stains on the equipment, and then the stains are rinsed clean by the water flow sprayed from the cleaning nozzle 12. In the cleaning process, a large amount of water is often required for rinsing, and the fan-shaped cleaning nozzle 12 can accurately determine the minimum amount of water required according to the amount of foaming, and can recover part of the water as the water supply source of the foaming agent through the counterclockwise rotation of the cleaning roller brush 6, thereby achieving the effect of efficient use of water.
