[0037] See also Figure 1 and Figure 2 An embodiment of the utility model provides a bubble cleaning assembly, which includes a screen component 100 and a bubble component 200.

[0038] The screen component 100 includes a first screen 110 and a second screen 120. The second screen 120 is arranged at the edge of the first screen 110 and is enclosed with the first screen 110 to form a cleaning space. The shape of the first screen 110 can be rectangular, square or circular, and the utility model does not limit the shape of the first screen 110. The second screen 120 is installed on the edge of the first screen 110 by a fixed connection method (such as welding or riveting) or a detachable connection method (such as screw or bolt connection). The second screen 120 and the first screen 110 can be perpendicular to each other, or they can be arranged at a certain angle to each other, that is, the second screen 120 is inclined relative to the first screen 110. The first screen 110 and the second screen 120 cooperate to enclose a cleaning space, and the material to be washed is located in the cleaning space.

[0039] Among them, the material to be washed can be a bio-based material, and can also be used for the cleaning of vegetables, aquatic products, red dates, and jujubes, as well as carrots, apples, potatoes, potatoes, etc. It is suitable for fruits and vegetables grown in the soil, has a high degree of cleaning, and can maintain the original color.

[0040] The bubble assembly 200 can be detachably connected to at least one of the first screen 110 and the second screen 120, that is, the bubble assembly 200 can be connected to the first screen 110, and air is supplied from the bottom of the cleaning space so that the airflow and water are combined to form a tumbling state to wash the material to be washed. The bubble assembly 200 can also be connected to the second screen 120, and air is supplied from the side of the cleaning space so that the airflow and water are combined to form a tumbling state to wash the material to be washed. The bubble assembly 200 can also be set on the first screen 110 and the second screen 120 at the same time, and air is supplied from the bottom and side of the cleaning space at the same time.

[0041] The bubble assembly 200 includes an air pipe 210 and a plurality of exhaust components 220. The air pipe 210 is connected to an air source. The plurality of exhaust components 220 are arranged at intervals on the air pipe 210. Each exhaust component 220 is connected to the air pipe 210 to supply air to the cleaning space. The air source may be a vacuum device or a blower, and the gas is supplied to the cleaning space through the blower or the vacuum device.

[0042] It is understandable that the embodiment of the utility model is provided with a screen component 100 and a bubble component 200, and the bubble component 200 is detachably connected to at least one of the first screen 110 and the second screen 120 of the screen component 100. Such a configuration facilitates the disassembly and installation of the bubble component 200, facilitates the replacement of the bubble component 200, has a relatively simple structure, and has a low manufacturing cost. When it is necessary to clean the material to be cleaned (such as bio-based materials), the bubble cleaning component is placed in a water container, and the air source inputs air into the water container to form bubbles. The bubbles drive the water flow to turn over, thereby driving the material to be cleaned to roll for cleaning. The energy generated by the bubbles bursting when in contact with the material to be cleaned will have an impact and scrubbing effect on the surface of the material to be cleaned, and the material to be cleaned will be cleaned more conveniently. It can effectively solve the problem that the material to be cleaned (such as bio-based materials) using the cleaning equipment in the related technology is easily damaged by the mechanical structure, or easily entangled on the agitator, and is very inconvenient to clean.

[0043] Continue reading Figure 2 In some embodiments of the utility model, the exhaust component 220 includes an exhaust pipe body 221, and the first end of the exhaust pipe body 221 is provided with a connecting portion 2211, and the connecting portion 2211 is detachably connected to the first screen 110 or the second screen 120; the second end of the exhaust pipe body 221 is provided with a thread 2212, and the exhaust pipe body 221 is threadedly connected to the air pipe 210 through the thread 2212.

[0044] Among them, the connecting part 2211 can be a nut or a stop flange. When the connecting part 2211 is a nut, it is equivalent to that the connecting part 2211 is threadedly connected to the exhaust pipe body 221. A limiting step can be set on the exhaust pipe body 221. When the exhaust pipe body 221 is passed through the first screen 110 or the second screen 120, the limiting step abuts against the corresponding first screen 110 or the second screen 120, and then cooperates with the exhaust pipe body 221 through the nut to detachably connect the exhaust pipe body 221 with the first screen 110 or the second screen 120.

[0045] When the connecting portion 2211 is a stop flange, it is equivalent to that the stop flange is integrally formed with the exhaust pipe body 221, and the diameter or size of the stop flange is larger than the exhaust pipe body 221. The exhaust pipe body 221 can be passed through the first screen 110 or the second screen 120 and suspended on the first screen 110 or the second screen 120 through the stop flange.

[0046] The exhaust pipe body 221 is threadedly connected to the air pipe 210 via the thread 2212 . It can be understood that the material of the air pipe 210 has a certain hardness, that is, the air pipe 210 is made of a rigid material, which can support the exhaust pipe body 221 and be threadedly connected to the exhaust pipe body 221 .

[0047] When the material of the air pipe 210 is relatively soft, the exhaust component 220 further includes a sleeve 222 made of a rigid material. The sleeve 222 is sleeved on the outer surface of the air pipe 210 , and the exhaust pipe body 221 is threadedly connected to the sleeve 222 via a thread 2212 .

[0048] The connection between the sleeve 222 and the trachea 210 includes any of the following:

[0049] An installation method: a plurality of exhaust holes corresponding to the number of exhaust components 220 are evenly spaced on the air pipe 210, a threaded hole 2212 is opened on the sleeve 222, the sleeves 222 are sequentially sleeved on the air pipe 210, and the threaded hole 2212 of each sleeve 222 is made to correspond to the position of the air hole, so that the exhaust pipe body 221 is threadedly connected to the threaded hole 2212 of the sleeve 222, so that the exhaust pipe body 221 can be connected to the air pipe 210.

[0050] Another installation method: the trachea 210 is composed of multiple segments, the sleeve 222 is located between two adjacent segments of the trachea 210, and a threaded hole 2212 is opened on the sleeve 222. In this way, the exhaust pipe body 221 is threadedly connected to the threaded hole 2212 of the sleeve 222, so that the exhaust pipe body 221 can be connected to the trachea 210. At this time, the sleeve 222 can serve as a part of the trachea 210.

[0051] Figure 3 It is a schematic diagram of the assembly of the exhaust pipe body 221 and the non-return structure 223 in the bubble cleaning assembly provided by the embodiment of the utility model; Figure 4 It is a top view of the exhaust pipe body 221 in the bubble cleaning assembly provided in the embodiment of the present utility model.

[0052] See also Figure 3 A non-return structure 223 is provided inside the exhaust pipe body 221 , and the non-return structure 223 is used to prevent the cleaning liquid from flowing back to the air pipe 210 .

[0053] The non-return structure 223 includes a valve seat and a valve body, wherein the valve seat is rotatably mounted inside the exhaust pipe body 221 through an elastic member, and the valve body is fixed on the valve seat to prevent the cleaning liquid from flowing back to the air pipe 210. In addition, the non-return structure 223 can also be a non-return valve arranged on the exhaust pipe body 221.

[0054] See also Figure 4 In some embodiments of the present invention, a mounting plane 2211 - 1 is provided on at least one of the inner wall of the connecting portion 2211 and the outer wall of the connecting portion 2211 .

[0055] For example, when the connection part 2211 is a nut, any plane on the outer surface of the nut is equivalent to the installation plane 2211-1, and the connection part 2211 can be quickly disassembled by using auxiliary tools (such as a wrench).

[0056] When the connection portion 2211 is a stop flange, the stop flange may be configured to have a hexagonal hollow structure, so that the exhaust component 220 may be quickly disassembled by using an auxiliary tool (such as a hexagon socket).

[0057] Continuing to refer to the figure, in some embodiments of the utility model, the air pipe 210 is provided with a quick-release chuck 224 for connecting to the air source, and the air source is quickly connected to the air pipe 210 through the quick-release chuck 224. The quick-release chuck 224 can be a structure such as a clamp or a flange, and the specific structure is set according to the connection end of the air source.

[0058] Continue reading Figure 1 and Figure 2 In some embodiments of the present invention, the air flow cross section of the exhaust component 220 gradually increases from one end close to the air source to the direction away from the air source. This arrangement enables the air flow of each exhaust component 220 to be uniformly delivered into the cleaning space.

[0059] In some embodiments of the present invention, the diameter of the air flow section of the exhaust component 220 farthest from the air source is less than or equal to half the diameter of the air pipe 210. This arrangement can not only ensure that the air flow of each exhaust component 220 is evenly delivered to the cleaning space, but also effectively prevent the substances to be cleaned (such as bio-based materials) from entering the air pipe 210 to block the air pipe 210.

[0060] For example, a first exhaust component 220, a second exhaust component 220, a third exhaust component 220 and a fourth exhaust component 220 are sequentially arranged on one side of the second screen 120, wherein the area of ​​the airflow cross section of the first exhaust component 220 is less than or equal to the area of ​​the airflow cross section of the second exhaust component 220, the area of ​​the airflow cross section of the second exhaust component 220 is less than or equal to half the area of ​​the airflow cross section of the third exhaust component 220, the area of ​​the airflow cross section of the third exhaust component 220 is less than or equal to half the area of ​​the airflow cross section of the fourth exhaust component 220, and the area of ​​the airflow cross section of the fourth exhaust component 220 is less than or equal to half the diameter of the air pipe 210.

[0061] When the first exhaust component 220, the second exhaust component 220, the third exhaust component 220 and the fourth exhaust component 220 respectively include an exhaust pipe body 221, the aperture of the first exhaust pipe body 221 is less than or equal to the aperture of the second exhaust pipe body 221, the aperture of the second exhaust pipe body 221 is less than or equal to half the aperture of the third exhaust pipe body 221, the aperture of the third exhaust pipe body 221 is less than or equal to half the aperture of the fourth exhaust pipe body 221, and the aperture of the fourth exhaust pipe body 221 is less than or equal to half the diameter of the air pipe 210.

[0062] In some embodiments of the present invention, in order to facilitate the application of force to the bubble cleaning assembly so as to install and disassemble the bubble cleaning assembly as a whole, a handle 130 is provided on the second screen 120 .

[0063] Continue reading Figure 1 and Figure 2 A plurality of groups of bubble components 200 are arranged in an array along the length direction of the first screen 110 , and the arrangement directions of two adjacent groups of bubble components 200 are opposite.

[0064] It is equivalent to that each group of bubble components 200 includes an air pipe 210 and four exhaust components 220 arranged on the air pipe 210, and the four exhaust components 220 are arranged in an array in sequence along the length direction of the air pipe 210, and the area of ​​the air flow cross section of the exhaust components 220 gradually decreases along the length direction of the air pipe 210. A plurality of such bubble components 200 are arranged in an array along the length direction of the first screen 110, and the arrangement directions of two adjacent groups of bubble components 200 are opposite, that is, the exhaust component 220 with the largest air flow cross section in one group of bubble components 200 is arranged in parallel with the exhaust component 220 with the smallest air flow cross section in another group of bubble components 200. This arrangement can make the air flow in the washing space more uniform and the cleaning effect better.

[0065] In some embodiments of the present invention, the first screen 110 and the second screen 120 are both provided with screen holes, and the aperture of the screen holes is 0.1mm to 10mm. The total height of the first screen 110 and the second screen 120 is 10mm to 15mm, that is, the thickness of the screen component 100 is 10mm to 15mm.

[0066] It should be noted that the first screen 110 and the second screen 120 are made of stainless steel or polytetrafluoroethylene.

[0067] The utility model also provides a bubble cleaning device, which comprises a device body and any one of the above-mentioned bubble cleaning components, wherein the bubble cleaning component is arranged on the device body.

[0068] Among them, a circulating water supply system and a drainage system are arranged in the equipment body. The circulating water supply system supplies water to the equipment body so that the bubble cleaning component is immersed in the water, and the drainage system can quickly discharge the water after cleaning.

[0069] In addition, a heating device may be provided on the device body to heat the water in the device body so as to use warm water for cleaning and improve the washing efficiency.

[0070] It should be noted that the technical solutions in various embodiments of the present utility model can be combined with each other, but the basis for the mutual combination is that it can be implemented by ordinary technicians in the field; when the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist, that is, it does not belong to the protection scope of the present utility model.

[0071] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
