[0001] The utility model relates to the field of household appliances especially relates to a cleaning device. BACKGROUND

[0002] People in daily life clean food materials by hand washing or with chemical compound cleaning agent. This method has the following problems: (1) chemical reagent (cleaning agent) is needed for deep cleaning, which may cause chemical residue; (2) the uneven surface of food materials is difficult to clean and needs to be cleaned with cleaning tools, which may cause damage to the surface of food materials; (3) if the washing force is not enough when washing food materials with a water column, the food materials may not be cleaned thoroughly, and if the washing force is too large, the surface of food materials may be damaged, and even the overall structure of food materials may be destroyed (for example, food materials such as tofu are easy to break). In addition, the existing cleaning method also has the problem of low cleaning efficiency.

[0003] To solve the above problems, a device for cleaning food materials is developed. For example, a Chinese invention patent with application number CN202011066316.2 (publication number CN112244670A) discloses a fruit and vegetable cleaning machine, and specifically discloses the following content: a box body and a water pump mechanism, a water storage box, the water storage box is arranged on the bottom wall outside the box body and has a water outlet at the top, the bottom wall of the box body is provided with a water passage corresponding to the water outlet, the water pump mechanism includes a spray arm, an impeller assembly and a motor, the spray arm is arranged at the bottom of the washing cavity and has a water inlet corresponding to the water passage on the bottom wall, the impeller assembly is rotatably arranged in the water storage box and the upper part penetrates the water inlet and extends into the spray arm, the motor is arranged at the bottom of the water storage box and the output shaft penetrates the bottom wall of the water storage box and is connected with the impeller assembly, the output shaft of the motor is hollow to form a gas guide pipe for adding gas to the water flow of the washing cavity.

[0004] However, although the above-mentioned fruit and vegetable cleaning machine can improve the cleaning efficiency, it still cannot solve the problems of poor cleaning effect (food material surface is easy to cause dirt residue and other conditions), damage to the surface of food materials and other problems existing in the prior art.

In this way, the water pressure of the micro-nano bubble water gradually increases when flowing along the atomization flow channel, which is beneficial to improve the atomization effect.

[0008] Further, the water inlet of the first flow channel is curved along the length direction thereof and deviates from one side of the atomization flow channel, which has the effect of pressurizing the water flow. The water outlet extends linearly with the second flow channel and the third flow channel, which can ensure pressurizing the water flow and enable the atomized water to be smoothly sprayed from the water outlet.

The water storage chamber is provided with a water storage inlet on one side and a water storage outlet on the other side. The water storage outlet is arranged opposite to the water storage inlet and has a higher height than the water storage inlet. The water storage inlet is in fluid communication with the first water inlet, and the water storage outlet is in communication with the water inlet of the first flow channel. In this way, as the water flow continuously flows into the water storage chamber, the water pressure in the water storage chamber increases, and the water storage outlet is higher than the water storage inlet, so as to further increase the water pressure.

[0010] Further, a water inlet connector with a filter screen is arranged on the first water inlet of the water sprayer, so as to filter the water flow entering the water sprayer. The water inlet connector is connected to the first water outlet of the micro-nano bubble generator through a water inlet pipe that is retractable along the length direction thereof, which facilitates a user to adjust the position of the water sprayer according to the cleaning needs.

[0011] Further, one end of the water inlet pipe is provided with a spherical connecting connector, and a connecting seat for embedding the connecting connector is arranged in the corresponding interface of the water inlet connector. When the connecting connector and the connecting seat are connected, the first water inlet of the water sprayer and the first water outlet of the micro-nano bubble generator are in communication. In this way, the water inlet pipe and the water sprayer can be easily disassembled and assembled, and reliable communication between the two can be ensured.

[0013] Further, the spray head and the body are detachably connected to splice the first flow channel with the second flow channel and the third flow channel to form the atomizing flow channel. Thus, the water sprayer can be easily disassembled and cleaned.

[0014] Further, the body has a long block shape, the first flow channel is arranged along the length direction of the body, the first water inlet port is formed at one end of the body, the water outlet port of the first flow channel is formed at the other end of the body, the water outlet port is threadedly connected with the spray head, and a first sealing ring is arranged at the connection position of the water outlet port and the spray head. Thus, the spray head and the body can be firmly connected to form the water sprayer, and water leakage at the connection position can be avoided.

[0015] Further, the body is detachably covered with a cover shell at the water outlet port of the first flow channel to form a space for accommodating the spray head, the cover shell is provided with a spraying outlet opposite to the water spraying port of the spray head, and a second sealing ring is arranged between the edge of the spraying outlet and the edge of the water spraying port in the circumferential direction. The cover shell can protect the spray head from damage during daily use, and water can be prevented from penetrating into the gap between the cover shell and the spray head.

[0016] Further, the water supply circuit for supplying water to the micro-nano bubble generator comprises a water inlet valve for controlling the opening and closing of the water supply circuit and a water pump.

[0017] Further, the water supply circuit further comprises a flow-through electrolytic ozone water module, the second water inlet port of the water inlet valve is connected with a water source, the second water outlet port of the water inlet valve is in fluid communication with the fifth water inlet port of the flow-through electrolytic ozone water module, the fifth water outlet port of the flow-through electrolytic ozone water module is in fluid communication with the third water inlet port of the water pump, and the third water outlet port of the water pump is in fluid communication with the fourth water inlet port of the micro-nano bubble generator.

[0018] Compared with existing technologies, the advantages of this invention are as follows: It incorporates a micro / nano bubble generator and a water sprayer. The micro / nano bubble generator produces micro / nano bubble water (particle size between tens of nm and tens of μm). This micro / nano bubble water can penetrate into the hidden fine structures of the surface of the object to be cleaned, removing dirt that conventional methods cannot reach. Furthermore, its self-charged properties allow it to adsorb dirt from the surface of the object and the water. Simultaneously, the bursting of micro / nano bubble water on the surface of the object helps loosen and remove surface dirt, preventing surface damage during the cleaning process. Further, the atomizing channel in the water sprayer atomizes the micro / nano bubble water into microjets, maintaining the water flow impact speed while reducing the impact intensity.

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0028] like Figures 1 to 6 As shown, a cleaning device includes a water tank 1, a micro / nano bubble generator 2, and a sprayer 3 for spraying water into the water tank 1. The sprayer 3 has a first inlet 31 and a spray nozzle 32, and its interior is horizontally provided with an atomizing channel 30 for atomizing water. The inlet end of the atomizing channel 30 is in fluid communication with the first inlet 31, and the outlet end is in fluid communication with the spray nozzle 32. Furthermore, the first inlet 31 is in fluid communication with the first outlet 21 of the micro / nano bubble generator 2. The micro / nano bubble generator 2 in this invention adopts a conventional structure.

[0029] As can be seen from the above, the cleaning device of this utility model is equipped with a micro-nano bubble generator 2 and a water sprayer 3. The micro-nano bubble generator 2 generates micro-nano bubble water (particle size between tens of nm and tens of μm). This micro-nano bubble water can penetrate into the hidden fine structures on the surface of the object to be cleaned (e.g., food), cleaning dirt that conventional methods cannot reach. Furthermore, its self-charged properties allow it to adsorb dirt from the surface of the object and the water. Simultaneously, the bursting of micro-nano bubble water on the surface of the object helps loosen and remove surface dirt, preventing surface damage during the cleaning process. Further, the atomizing channel 30 in the water sprayer 3 atomizes the micro-nano bubble water into a micro-jet, ensuring the water flow impact speed while reducing the impact intensity. This better avoids surface damage during the cleaning process and allows the micro-nano bubble water to better penetrate the uneven areas of the object's surface, improving the cleaning effect.

[0030] Furthermore, the aforementioned atomizing channel 30 includes a first channel 301, a second channel 302, and a third channel 303 continuously arranged along its length, with their radii decreasing sequentially. The first channel 301 is adjacent to the first water inlet 31, while the third channel 303 is adjacent to the spray nozzle 32. This allows the water pressure to gradually increase as the micro-nano bubble water flows along the atomizing channel 30, which is beneficial for improving the atomization effect. Preferably, the water inlet end of the first channel 301 is curved and deviates from one side of the atomizing channel 30 along its length, thus pressurizing the water flow. The water outlet end extends in a straight line with the second channel 302 and the third channel 303, ensuring that the atomized water is smoothly sprayed from the spray nozzle 32 while simultaneously pressurizing the water flow.

[0031] Furthermore, the aforementioned water sprayer 3 also includes a vertically oriented cylindrical water storage chamber 33. One side of the water storage chamber 33 has a water inlet 331, and the other side has a water outlet 332. The water outlet 332 is directly opposite the water inlet 331 and is higher than the water inlet 331. The water inlet 331 is in fluid communication with the first water inlet 31, while the water outlet 332 is connected to the water inlet port of the first flow channel 301. Thus, as water continuously flows into the water storage chamber 33, the water pressure in the water storage chamber 33 increases, and since the water outlet 332 is higher than the water inlet 331, the water pressure can be further increased.

[0032] Furthermore, the first inlet 31 of the sprayer 3 is equipped with an inlet connector 4 with a filter screen 41, which filters the water entering the sprayer 3. The inlet connector 4 is connected to the first outlet 21 of the micro / nano bubble generator 2 via a retractable inlet pipe 40 (a flexible hose in this embodiment) along its length, allowing the user to easily adjust the position of the sprayer 3 according to cleaning needs. Preferably, one end of the inlet pipe 40 is provided with a spherical connector 401, and the corresponding interface of the inlet connector 4 is provided with a connecting seat 42 for the connector 401 to be fitted. When the connector 401 is connected to the connecting seat 42, the first inlet 31 of the sprayer 3 is connected to the first outlet 21 of the micro / nano bubble generator 2. This facilitates the assembly and disassembly of the inlet pipe 401 and the sprayer 3, and ensures reliable communication between them during assembly.

[0033] Furthermore, the aforementioned water sprayer 3 includes a block-shaped body 3a and a nozzle 3b. The first flow channel 301 is formed in the body 3a, while the second flow channel 302 and the third flow channel 303 are respectively formed in the nozzle 3b, and the water outlet of the third flow channel 303 constitutes the water spray nozzle 32. Moreover, the nozzle 3b and the body 3a are detachably connected so that the first flow channel 301, the second flow channel 302, and the third flow channel 303 can be joined to form the atomizing flow channel 30. This facilitates the assembly and disassembly of the water sprayer 3 and makes it easy to clean dirt (such as scale from long-term use) from the atomizing flow channel 30.

[0034] Specifically, in this embodiment, the body 3a is elongated, the first flow channel 301 is arranged along the length of the body 3a, and one end of the body 3a has the first water inlet 31 and the other end has the water outlet of the first flow channel 301. The water outlet is threadedly connected to the nozzle 3b, and a first sealing ring 5 is provided at the connection between the two. This allows the nozzle 3b to be firmly connected to the body 3a to form a water sprayer 3, and prevents water leakage at the connection. Furthermore, the body 3a is detachably covered with a cover 7 at the water outlet of the first flow channel 301 to form a space 70 for accommodating the nozzle 3b. The cover 7 has a spray outlet 71 that is directly opposite the spray nozzle 32 of the nozzle 3b, and a second sealing ring 6 is circumferentially sandwiched between the edge of the spray outlet 71 and the edge of the spray nozzle 32. The cover 7 protects the nozzle 3b from damage during daily use and prevents water from seeping into the gap between the cover 7 and the nozzle 3b.

[0035] Furthermore, it also includes a water supply path for supplying water to the aforementioned micro / nano bubble generator 2. This water supply path includes an inlet valve 8 and a water pump 9 for controlling the opening and closing of the water supply path. Specifically, in this embodiment, the aforementioned inlet valve 8, water pump 9, and micro / nano bubble generator 2 are all disposed on the back side of the aforementioned water tank 1, while the aforementioned water sprayer 3 is disposed on the rear side wall of the water tank 1 along the front-to-back direction. Moreover, the second inlet 81 of the inlet valve 8 is connected to a water source, the second outlet 82 of the inlet valve 8 is fluidly connected to the third inlet 91 of the water pump 9, and the third outlet 92 of the water pump 9 is fluidly connected to the fourth inlet (not shown) of the aforementioned micro / nano bubble generator 2.

[0036] Example 2:

[0037] Unlike Embodiment 1, the water supply circuit in this embodiment further includes a flow-through electrolytic ozone water module 10. The second inlet 81 of the aforementioned inlet valve 8 is connected to the water source, while the second outlet 82 of the inlet valve 8 is fluidly connected to the fifth inlet 101 of the flow-through electrolytic ozone water module 10. The fifth outlet 102 of the flow-through electrolytic ozone water module 10 is fluidly connected to the third inlet 91 of the water pump 9, and the third outlet 92 of the water pump 9 is fluidly connected to the fourth inlet of the aforementioned micro-nano bubble generator 2. By setting the flow-through electrolytic ozone water module 10 to electrolyze water to produce oxygenated water, the oxygenated water enters the micro-nano bubble generator 2 to produce oxygenated micro-nano bubble water with bactericidal effect. Spraying the atomized oxygenated micro-nano bubble water onto items can sterilize and remove pesticide residues (when cleaning food). The flow-through electrolytic ozone water module 10 in this invention adopts an existing structure.

[0038] The term "fluid connectivity" as used in this utility model refers to the spatial relationship between two components or parts (hereinafter referred to as the first part and the second part, respectively), that is, a fluid (gas, liquid, or a mixture of both) can flow from the first part along a flow path and / or be transported to the second part. This can be a direct connection between the first part and the second part, or an indirect connection between the first part and the second part through at least one third party. The third party can be a fluid channel such as a pipe, channel, conduit, guide, hole, or groove, or a chamber or combination thereof that allows fluid to flow through.
