[0024] In an optional embodiment, the diameter of the spray holes near the center of the spray head is smaller than the diameter of the spray holes near the edge of the spray head.

[0025] Beneficial Effect: Because the spray holes near the center of the spray head have smaller diameters, they generate higher cleaning liquid pressure. Combined with the smaller spray angles, these holes can clean the inner wall of the cabinet farther from the spray head. Meanwhile, the spray holes near the edge of the spray head have larger spray angles, allowing them to clean the inner wall closer to the spray head. Therefore, the combination of the spray hole diameter and spray angle allows for comprehensive cleaning of the cabinet's inner wall, ensuring efficient cleaning.

[0058] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are 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 those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0059] With the rapid development of science and technology, people's living standards are getting higher and higher, and people's requirements for quality of life are also getting higher and higher. Various cleaning equipment are widely used in home environments.

[0060] Cleaning equipment such as floor scrubbers, vacuum cleaners, and sweepers work by sucking sewage or stains on the surface to be cleaned into a sewage collection box of the cleaning equipment under the action of a negative pressure device. When the sewage or stains in the sewage collection box reach a certain amount, the sewage collection box is cleaned manually, and the inner wall of the sewage collection box needs to be cleaned manually frequently, which brings a bad user experience.

[0061] Related technology has developed a self-cleaning dirt collecting box, comprising: a box body, one end of which is open facing upward; a water spray diffuser, which is installed at the open end of the box body, the peripheral side of the water spray diffuser is adapted to the inner wall of the open end of the box body, and has a nozzle corresponding to the inner wall of the box body, and the nozzle is used to spray cleaning water to the inner wall of the box body; the water spray diffuser has a water containing chamber, the nozzle is connected to the water containing chamber, and the water containing chamber is used to supply water to the nozzle; an adapter assembly, one end of which can be connected to an external water source, and the other end can be connected to the water containing chamber, so that the external water source can supply water to the water containing chamber through the adapter assembly.

[0062] The self-cleaning dirt collection box described above is equipped with a water diffuser that can directly spray cleaning water onto the inner wall of the box, cleaning the inner wall of the box and achieving self-cleaning of the dirt collection box. Since the water diffuser is provided with an annular cavity extending from the periphery of its top surface toward the interior, the annular cavity forms a water storage chamber, and the bottom of the water storage chamber is provided with multiple water outlets, which are distributed in a ring around the bottom of the chamber. There are also multiple nozzles, which are arranged in a circle around the outer circumference of the water diffuser. The nozzles correspond to the water outlets one-to-one and are connected. Water in the water storage chamber enters the nozzles through the water outlets and is sprayed out, achieving self-cleaning of the inner wall of the entire box. The water outlets and nozzles are formed on the water diffuser, making it inconvenient to replace the nozzles.

[0063] The following combination Figures 1 to 14 , describing the embodiments of the present utility model.

[0064] According to an embodiment of the present invention, on the one hand, a dirt collecting box is provided, comprising a box body 1 , a separator assembly 2 and a spray assembly 3 .

[0065] Among them, the separator assembly 2 is arranged in the box body 1; the spray assembly 3 includes a spray pipe 301 and a spray head 302 arranged at the first end of the spray pipe 301, the second end of the spray pipe 301 is suitable for connecting with the cleaning liquid source, and the spray head 302 is fixed to the separator assembly 2.

[0066] In this embodiment, by setting up a spray assembly 3, when the inside of the box body 1 needs to be cleaned, the cleaning liquid source can enter the spray head 302 through the spray pipe 301, and the cleaning liquid is sprayed onto the inner wall of the box body 1 through the spray head 302, thereby achieving the cleaning of the inner wall of the box body 1, reducing manual operations and improving user experience.

[0067] Specifically in one embodiment, the separator assembly 2 is detachably connected to the housing 1 .

[0068] Specifically in one embodiment, Figure 2 As shown, a sewage outlet can be provided at the bottom of the box body 1, and a sewage valve assembly 9 is provided at the sewage outlet. When cleaning the box body 1, the sewage valve assembly 9 can be opened and the sewage generated by flushing can be discharged through the sewage outlet, without the user having to remove the sewage collecting box from the body 4.

[0069] Of course, the bottom of the box body 1 may not be provided with a sewage outlet. After cleaning the inner wall of the box body 1, the sewage collecting box is disassembled from the fuselage 4, the sewage in the sewage collecting box is poured out, and then the sewage collecting box is returned to the fuselage 4.

[0070] In one embodiment, the separator assembly 2 includes a baffle 201 , the baffle 201 is provided with a mounting hole 2011 , and the spray head 302 passes through the mounting hole 2011 and is detachably connected to the baffle 201 .

[0071] In this embodiment, a mounting hole 2011 is provided on the baffle 201 , and the spray head 302 passes through the mounting hole 2011 and is detachably connected to the baffle 201 . The user can choose whether to install the spray assembly 3 according to needs.

[0072] Specifically, the mounting hole 2011 is arranged at a position close to the edge of the baffle 201 and will not affect the normal function of the baffle 201.

[0073] Specifically, when the sewage collecting box is used in a cleaning device, when the cleaning device is working, the vacuum motor module 8 generates negative pressure suction, and the airflow carries the sewage from the sewage suction pipe into the sewage collecting box and rushes toward the baffle 201. The airflow enters the inner cavity 2013 of the baffle 201 from the sewage suction pipe. As the space becomes larger, the flow rate is greatly reduced, and the sewage falls into the box body 1 under the action of gravity. The airflow enters the vacuum motor module 8 under the suction of the vacuum motor module 8, and the airflow and sewage are separated in this process.

[0074] Specifically in one embodiment, the separator assembly 2 further includes an upper cover 202 , which is disposed outside the baffle 201 and is suitable for covering the top of the box body 1 .

[0075] In one embodiment, Figure 13As shown, the baffle plate 201 is provided with a buckle 2012 , and the spray head 302 is fixed to the baffle plate 201 via the buckle 2012 .

[0076] In this embodiment, the spray head 302 is fixed to the deflector 201 by a buckle 2012, which facilitates the fixing and removal of the spray head 302. The user can choose whether to install the spray assembly 3 according to needs.

[0077] In an embodiment not shown in the figures, the shower head 302 can be fixed to the baffle 201 by screws.

[0078] In one embodiment, the spray head 302 is provided with a plurality of spray holes 30211 , and the plurality of spray holes 30211 have a plurality of spray angles, where the spray angle refers to the angle between the axis of the spray hole 30211 and the vertical axis.

[0079] In this embodiment, by arranging multiple spray holes 30211 on the spray head 302, a high-pressure impact liquid flow can be formed, and the cleaning liquid can be sprayed out evenly at the same time. Since the multiple spray holes 30211 have multiple spray angles, the flushing range is larger, and the inner wall of the box body 1 can be flushed in all directions, avoiding flushing dead corners and improving cleaning efficiency.

[0080] It should be noted that, multiple spray holes 30211 having multiple spray angles may specifically mean that the spray angles of each spray hole 30211 are different, or the spray holes 30211 may be divided into multiple groups, the spray angles of the same group of spray holes 30211 are the same, and the spray angles of different groups of spray holes 30211 are different.

[0081] In one embodiment, the spray angle of the spray hole 30211 gradually increases from the center of the shower head 302 to the edge of the shower head 302 .

[0082] In this embodiment, the spray angle of the spray hole 30211 gradually increases from the center of the spray head 302 to the edge of the spray head 302. The spray hole 30211 near the center of the spray head 302 can spray the cleaning liquid to the bottom wall of the box 1 and the inner wall of the box 1 farther away from the spray head 302. The spray hole 30211 near the edge of the spray head 302 can spray the cleaning liquid to the inner wall of the box 1 closer to the spray head 302. The flushing range is larger, and the inner wall of the box 1 can be flushed in all directions to avoid flushing dead corners and improve cleaning efficiency.

[0083] In one embodiment, the spray angle of the spray hole 30211 is A, 0°≤A≤80°.

[0084] In this embodiment, the spray angle of the spray hole 30211, that is, the angle between the axis of the spray hole 30211 and the vertical axis is between 0°-80°, and the flushing range is larger. The inner wall of the box body 1 can be flushed in all directions, avoiding flushing dead corners and improving cleaning efficiency.

[0085] Specifically, in one embodiment, the spraying angle of the spray hole 30211 located at the center of the spray head 302 is 0°, and the spraying angle of the spray hole 30211 located at the edge of the spray head 302 is 80°.

[0086] In one embodiment, the plurality of spray holes 30211 have a plurality of apertures.

[0087] In this embodiment, since the multiple spray holes 30211 have multiple apertures, different apertures can provide different cleaning liquid pressures, so that a better cleaning effect can be achieved for dirt at different positions on the inner wall of the box body 1.

[0088] It should be noted that, the multiple spray holes 30211 having multiple apertures may specifically mean that the apertures of the various spray holes 30211 are different, or the spray holes 30211 may be divided into multiple groups, the apertures of the spray holes 30211 in the same group are the same, and the apertures of the spray holes 30211 in different groups are different.

[0089] In one embodiment, the diameter of the spray hole 30211 is d, 0.05 mm ≤ d ≤ 1 mm.

[0090] In this embodiment, the spray hole 30211 has a relatively small aperture, which can effectively form a high-pressure impact liquid flow to ensure a cleaning effect.

[0091] In one embodiment, the diameter of the spray holes 30211 near the center of the shower head 302 is smaller than the diameter of the spray holes 30211 near the edge of the shower head 302 .

[0092] In this embodiment, the smaller diameter of the spray holes 30211 near the center of the spray head 302 allows for a higher cleaning liquid pressure. Combined with the smaller spray angle of the spray holes 30211 near the center, this allows for cleaning of the inner wall of the housing 1 farther from the spray head 302. The spray holes 30211 near the edge of the spray head 302, on the other hand, have a larger spray angle, allowing for cleaning of the inner wall of the housing 1 closer to the spray head 302. Therefore, the combination of the diameter of the spray holes 30211 and the spray angle allows for comprehensive cleaning of the inner wall of the housing 1, ensuring efficient cleaning.

[0093] Specifically in one embodiment, the aperture of the spray hole 30211 near the center of the spray head 302 is 0.05 mm, and the aperture of the spray hole 30211 near the edge of the spray head 302 is 1 mm. The aperture of the spray hole 30211 gradually increases from the center of the spray head 302 to the edge of the spray head 302.

[0095] In this embodiment, the docking joint 303 can be configured to connect multiple spray pipes 301 at the same time, and each spray pipe 301 is connected to a spray head 302. Specifically, when cleaning the box body 1, the cleaning liquid first enters the water storage chamber of the docking joint 303 through the water inlet 3033, and then flows to each spray head 302 through different spray pipes 301, which can improve the cleaning efficiency of the box body 1.

[0096] In one embodiment, a first pipe joint 3034 is provided at the water outlet, and the second end of the spray pipe 301 is plugged into the first pipe joint 3034 .

[0097] In this embodiment, by providing the first pipe joint 3034 at the water outlet, the second end of the spray pipe 301 is plugged into the first pipe joint 3034, which facilitates the assembly of the spray assembly 3 and improves assembly efficiency.

[0098] In one embodiment, the docking joint 303 includes a docking body 3031 and a bottom plate 3032 , and the bottom plate 3032 closes one side of the water storage chamber.

[0099] In this embodiment, the docking joint 303 includes a docking body 3031 and a bottom plate 3032, which facilitates processing and production of the docking body 3031 and the bottom plate 3032 respectively. After the bottom plate 3032 is connected to the docking body 3031, one side of the water storage chamber is closed.

[0100] Specifically, the docking body 3031 and the bottom plate 3032 can be connected together by glue, ultrasonic welding, thermal conduction welding, etc.

[0101] In one embodiment, Figure 11 and Figure 12 As shown, the spray assembly 3 further includes a water injection head 304 , which is inserted into the water inlet 3033 and is sealed with the water inlet 3033 via a sealing ring 305 .
