[0049] The cleaning equipment 100 provided in this application embodiment includes, but is not limited to, fabric cleaning machines, vacuum cleaners, and other equipment with negative pressure and water spraying functions, so as to quickly and deeply clean the surface to be cleaned.

[0050] Please see Figure 1 The cleaning device 100 provided in this application embodiment includes a device body 10, a pipeline assembly 20 and a brush head assembly 30, with the pipeline assembly 20 connecting the device body 10 and the brush head assembly 30.

[0051] See some examples. Figure 3 The brush head assembly 30 is also equipped with a water nozzle 31, and the pipeline assembly 20 is equipped with a water outlet connector 22 and a water circuit switch 23 connected to the water outlet connector 22. The water outlet connector 22 is connected to the water outlet nozzle 31 on the brush head assembly 30.

[0052] In some examples, the piping assembly 20 includes a piping body 21 and a clean water pipe. The piping body 21 is divided into an installation space for installing a water outlet connector 22 and a water circuit switch 23. The clean water pipe is connected to the water circuit switch 23. One end of the piping body 21 is connected to the brush head assembly 30.

[0053] In this embodiment of the application, the cleaning device 100 also includes a clean water tank and a clean water pump. The clean water tank is connected to a clean water pipe, and the clean water pump is installed on the pipe connecting the clean water tank and the clean water pipe. The working state of the clean water pump can be controlled by controlling the water circuit switch 23. When the clean water pump is in working state, the clean water in the clean water tank can be sprayed out through the water outlet nozzle 31 on the brush head assembly 30.

[0054] See some examples. Figure 3The end of the brush head assembly 30 furthest from the pipe assembly 20 is the end of the brush head assembly 30. A suction port 32 is provided on the end of the brush head assembly 30. The cleaning equipment 100 also includes a wastewater tank and a negative pressure generating component. The pipe body 21 is connected to the wastewater tank inlet via an inlet pipe, and the wastewater tank outlet is connected to an exhaust pipe, on which a negative pressure generating component is provided. When the negative pressure generating component is in operation, wastewater can be sucked in through the suction port 32 and flows into the wastewater tank through the brush head assembly 30, the pipe body 21, and the inlet pipe.

[0055] In some examples, the end of the brush head assembly 30 is fitted with a brush head for cleaning the surface to be cleaned, and the brush head may include bristles or a sponge, etc.

[0056] In some examples, the brush head assembly 30 is detachably connected to the tubing assembly 20; for example, the brush head assembly 30 can be configured to snap-fit ​​with the tubing assembly 20.

[0057] See some examples. Figure 3 The brush head assembly 30 includes a brush head body 33 and an mounting section 34. One end of the mounting section 34 is connected to the brush head body 33, and the other end of the mounting section 34, away from the brush head body 33, is mounted on the pipe assembly 20. The brush head body 33 and the mounting section 34 are arranged at an angle. In this example, by setting the brush head body 33 and the mounting section 34 at an angle, it is easier for the user to use the brush head assembly 30 to clean the surface to be cleaned.

[0058] In some examples, the included angle between the brush head body 33 and the mounting section 34 is in the range of 100° to 120°. For example, the included angle between the brush head body 33 and the mounting section 34 can be set to 100° to 105°, 105° to 110°, 110° to 115°, or 115° to 120°, etc.

[0059] See some examples. Figure 3 The main body of the pipeline 21 includes a first pipe section 211, a second pipe section 212, and a third pipe section 213, which are connected in sequence. The brush head assembly 30 is installed at one end of the first pipe section 211, and the water outlet connector 22 and the water circuit switch 23 are installed on the first pipe section 211. The second pipe section 212 has a corrugated hose to facilitate adjustment of the position of the brush head assembly 30 on the surface to be cleaned, making it convenient for users to use.

[0060] See some examples. Figure 1 The cleaning equipment 100 also includes a support plate 50, which is disposed on the outer side of the equipment body 10. The support plate 50 is used to support the second pipe section 212 to prevent the second pipe section 212 from contacting the ground. Please refer to [link / reference]. Figure 1 and Figure 2This illustrates that the second pipe section 212 is wrapped around the main body of the equipment 10.

[0061] In some examples, there is at least one support plate 50, which is detachably connected to the device body 10 or integrally formed on the device body 10.

[0062] Please see Figures 4-8 , Figure 4 This is a schematic diagram of the structure of a cleaning device 100 provided in some embodiments of this application. Figure 5 This is a schematic diagram of the structure of the support frame 40 installed on the device body 10 according to some embodiments of this application. Figure 6 Schematic diagram of the structure of the support frame 40 provided in some embodiments of this application Figure 1 , Figure 7 Schematic diagram of the structure of the support frame 40 provided in some embodiments of this application Figure 2 , Figure 8 This is a partial cross-sectional structural view of a cleaning device 100 provided in some embodiments of this application.

[0063] Please see Figure 4 The cleaning equipment 100 provided in this application embodiment also includes a support frame 40, which is installed on the equipment body 10.

[0064] Please see Figure 5 The support frame 40 includes a support part 41 and a receiving part 42, the receiving part 42 being connected to the support part 41. Please refer to [link / reference]. Figure 4 The support portion 41 is used to support at least the brush head assembly 30. See also... Figure 4 The receiving part 42 has a cleaning groove 421, and when the brush head assembly is supported on the support part 41, the end of the brush head assembly 30 extends into the cleaning groove 421.

[0065] It is worth noting that when the brush head assembly 30 is supported on the support part 41 and the end of the brush head assembly 30 extends toward the cleaning tank 421, a gap can be set between the end of the brush head assembly 30 and the bottom surface of the cleaning tank 421, or the end of the brush head assembly 30 can be set to contact the bottom surface of the cleaning tank 421.

[0066] Regarding the depth of the cleaning groove 421, in some examples, the depth of the cleaning groove 421 may be set to be no less than the length of the brush head on the brush head assembly 30 used for cleaning the surface to be cleaned.

[0067] In some examples, the support portion 41 and the receiving portion 42 may be integrally formed.

[0068] In some examples, the support frame 40 may be made of plastic.

[0069] Please see Figure 7In this embodiment of the application, the support part 41 also has a flow guiding structure 411, which is used to guide the water sprayed by the brush head assembly 30 to the cleaning tank 421.

[0070] The support part 41 provided in this embodiment not only supports the brush head assembly 30, but also helps the brush head assembly 30 to self-clean. Specifically, when the brush head assembly 30 needs to be cleaned, the brush head assembly 30 is supported on the support frame 40, the cleaning device 100 is started, and the user can operate the water circuit switch 23 so that clean water in the clean water tank inside the device body 10 can be sprayed out from the water outlet nozzle 31 on the brush head assembly 30. The sprayed clean water flows under the guidance of the flow guiding structure 411 on the support part 41, so as to flow to the cleaning tank 421 on the receiving part 42. The cleaning tank 421 can hold a certain amount of clean water, and the end of the brush head assembly 30 extends into the cleaning tank. The clean water in the cleaning tank 421 can be sucked into the brush head assembly 30 through the suction port 32 on the brush head assembly 30 and flow to the wastewater tank of the main body 10. The clean water flowing into the cleaning tank 421 and being sucked away through the suction port 32 on the brush head assembly 30 cleans the brush head at the end of the brush head assembly 30. Simultaneously, the water sucked in from the suction port 32 flows through the brush head assembly 30 and the pipeline assembly 20, rinsing the inside of both. In other words, the support frame 40 provided in this embodiment can work with the cleaning equipment 100 to achieve self-cleaning of the brush head assembly 30, avoiding the need for the user to clean the brush head of the brush head assembly 30.

[0071] In some embodiments, see Figure 6 The receiving part 42 includes a connecting section 422 and a receiving section 423. The connecting section 422 connects the support part 41 and the receiving section 423. The receiving section 423 has a cleaning groove 421. The receiving section 423 extends downward from the end connected to the support part 41 to the end connected to the receiving section 423.

[0072] In this embodiment, the shape of the support frame 40 matches the shape of the brush head assembly 30. Please refer to [link / reference]. Figure 4 The brush head assembly 30 includes a brush head body 33 and a mounting section 34. One end of the mounting section 34 is connected to the brush head body 33, and the end of the mounting section 34 facing away from the brush head body 33 is mounted on the tubing assembly 20. The brush head body 33 and the mounting section 34 are arranged at an angle. Please refer to [link / reference]. Figure 4 The mounting section 34 is supported on the support part 41, the brush head body 33 faces the connecting section 422 and the end of the brush head body 33 extends into the cleaning groove 421 of the receiving section 423.

[0073] When the brush head assembly 30 is supported on the support frame 40, the cleaning device 100 is started. The user can operate the water circuit switch 23 so that the clean water in the clean water tank of the device body 10 can be sprayed out from the water outlet nozzle 31 on the brush head assembly 30. The sprayed clean water flows under the guidance of the flow guiding structure 411 on the support part 41, flows between the brush head body 33 and the connecting section 422, and can flow along the connecting section 422 to the cleaning groove 421 on the receiving part 42.

[0074] See some examples. Figure 4 The support part 41 is horizontally arranged on the main body 10 of the device so that the mounting section 34 of the brush head assembly 30 is stably supported on the support part 41.

[0075] Regarding the support part 41 being horizontally arranged on the equipment body 10, and the length extension direction of the support part 41 along... Figure 4 In the X-axis direction, or the length extension direction of the support 41, along the Figure 4 The small angle between the X-axis and the support part 41 is horizontally arranged on the main body 10 of the equipment.

[0076] In one example, the support portion 41 may be arranged laterally and slightly inclined downwards from the direction away from the receiving portion 42 to the direction closer to the receiving portion 42, so that the clean water sprayed from the water nozzle 31 flows along the guide structure 411 to the receiving portion 42, so as to prevent water from accumulating in the guide structure 411.

[0077] In some examples, the support portion 41 is arranged laterally and tilted downward at an angle of 0° to 10° from the direction away from the receiving portion 42 to the direction near the receiving portion 42. For example, the angle of downward tilt of the support portion 41 from the direction away from the receiving portion 42 to the direction near the receiving portion 42 may be 0° to 2°, 2° to 4°, 4° to 6°, 6° to 8°, or 8° to 10°, etc.

[0078] In some examples, the length extension direction of the support portion 41 is at an angle to the length extension direction of the connecting segment 422 (the length extension direction of the connecting segment 422 is the direction from the end where the connecting segment 422 is connected to the support portion 41 to the end where the connecting segment 422 is connected to the receiving segment 423), and the angle is greater than 90°.

[0079] In some examples, the angle between the length extension direction of the support 41 and the length extension direction of the connecting section 422 is equal to or approximately equal to the angle between the brush head body 33 and the mounting section 34.

[0080] The angle between the length extension direction of the support part 41 and the length extension direction of the connecting section 422 is approximately equal to the angle between the brush head body 33 and the mounting section 34. This can be understood as the difference between the angle between the length extension direction of the support part 41 and the length extension direction of the connecting section 422 and the angle between the brush head body 33 and the mounting section 34 being very small. For example, the difference between the angle between the length extension direction of the support part 41 and the length extension direction of the connecting section 422 and the angle between the brush head body 33 and the mounting section 34 can be set to be no greater than 10°.

[0081] In some examples, the angle between the length extension direction of the support portion 41 and the length extension direction of the connecting section 422 is 100° to 120°. For example, the angle between the length extension direction of the support portion 41 and the length extension direction of the connecting section 422 can be set to 100° to 105°, 105° to 110°, 110° to 115°, or 115° to 120°, etc.

[0082] In some examples, the receiving section 423 is set horizontally so that the cleaning tank 421 of the receiving section 423 can hold more clean water.

[0083] Regarding the horizontal setting of the receiving section 423, if the bottom surface of the receiving section 423 is parallel to... Figure 4 The XOY plane is parallel to the center, or the bottom surface of the connecting section 423 is parallel to the center. Figure 4 The XOY plane is slightly tilted, and both can be referred to as the horizontal setting of the connecting section 423.

[0084] See some examples. Figure 8 Since the suction port 32 on the brush head assembly 30 is located away from the connecting section 422, the receiving section 423 can be set to tilt slightly downwards in the direction close to the connecting section 422 and away from the connecting section 422, so that the water in the cleaning tank 421 flows towards the side close to the suction port 32 on the brush head assembly 30, so that the cleaning tank 421 can be sucked away.

[0085] In some examples, the angle at which the receiving segment 423 tilts downward along the direction close to the connecting segment 422 to the direction away from the connecting segment 422 may not exceed 5°.

[0086] In this embodiment of the application, by providing the receiving part 42 including the connecting section 422 and the receiving section 423, the shape of the support frame 40 is matched with the shape of the brush head assembly 30, so that the support frame 40 can both support the brush head assembly 30 and cooperate with the brush head assembly 30 to achieve the self-cleaning function of the brush head assembly 30.

[0087] In some embodiments, see Figure 7The support part 41 has a downward protruding groove 412 that extends to the connecting section 422. The groove 412 forms a flow guiding structure 411 and can avoid the water nozzle 31 on the brush head assembly 30.

[0088] Please see Figure 8 The water outlet connector 22 of the pipeline assembly 20 and the water outlet nozzle 31 on the brush head assembly 30 are located in the groove 412. The clean water sprayed from the water outlet nozzle 31 can flow along the groove 412 to the brush head body 33 and the connecting section 422.

[0089] In some examples, the depth of the groove 412 may be gradually increased from the end furthest from the receiving part 42 to the end closest to the receiving part 42 in order to guide the clean water flow toward the receiving part 42.

[0090] In this embodiment, the flow guiding structure 411 is formed by the groove 412 on the support part 41, which makes the structure of the support frame 40 simple and facilitates the processing of the support frame 40. At the same time, it can stably guide the clean water sprayed from the water nozzle 31 to the connecting section 422.

[0091] It is worth noting that the above embodiment describes the groove 412 on the support 41 forming a flow guiding structure 411. In other embodiments, the groove 412 may not be provided on the support 41. Instead, a support frame may be provided on the inner side of the support 41 (i.e. the side of the support 41 facing the brush head assembly 30). The water outlet connector 22 of the pipeline assembly 20 and the water outlet nozzle 31 on the brush head assembly 30 are supported by the support frame to limit the brush head assembly 30 on the support frame 40. In this case, the inner side of the support 41 forms a flow guiding structure 411.

[0092] When the support portion 41 has a downwardly protruding groove 412, in some embodiments, please refer to Figure 7 The support frame 40 also includes a limiting plate 43, which is disposed in the groove 412. The limiting plate 43 is provided with a limiting groove 431, and the water nozzle 31 can extend into the limiting groove 431 to position the water nozzle 31 on the support frame 40.

[0093] In some examples, the limiting plate 43 may be integrally formed on the support portion 41; of course, in other examples, the limiting plate 43 may be detachably connected to the support portion 41.

[0094] In some examples, the number of limiting plates 43 is at least one, and when the number of limiting plates 43 is two or more, the limiting plates 43 are spaced apart along the length direction of the groove 412.

[0095] See some examples. Figure 7The limiting groove 431 includes a first wall surface 4311, a second wall surface 4312, and a third wall surface 4313. The first wall surface 4311 and the second wall surface 4312 are arranged at intervals relative to each other, and the third wall surface 4313 is connected to the bottom of the first wall surface 4311 and the bottom of the second wall surface 4312.

[0096] In some examples, the first wall surface 4311, the second wall surface 4312, and the third wall surface 4313 of the limiting groove form a square shape.

[0097] In some examples, elastic components may be provided on the first wall surface 4311 and the second wall surface 4312 of the limiting groove, and the water nozzle 31 may squeeze the elastic components to stably support the brush head assembly 30 on the support frame 40.

[0098] In this embodiment of the application, by providing a limiting plate 43 in the groove 412, the water nozzle 31 can be positioned on the limiting plate 43, so as to stably support the brush head assembly 30 on the support frame 40.

[0099] In some embodiments, see Figure 4 The shape of the cleaning groove 421 matches the shape of the end of the brush head assembly 30. That is, in this embodiment, the shape of the cleaning groove 421 can be set to be substantially the same as the shape of the end of the brush head assembly 30, and the cleaning groove 421 can be set to be larger or slightly larger than the end of the brush head assembly 30, so that the volume of the cleaning groove 421 can be minimized as much as possible while the end of the brush head assembly 30 is inserted into the cleaning groove 421.

Figure 7The first support section is provided with a clearance hole 415, which is used to avoid the water circuit switch 23 on the pipeline assembly 20; that is, the water circuit switch 23 can extend through the clearance hole 415. Please refer to [link / reference]. Figure 4 This illustrates that the end of the tubing assembly 20 near the brush head assembly 30 (i.e., part of the first tubing segment 211) is also supported on the support part 41.

[0103] In this embodiment, the end of the pipeline assembly 20 near the brush head assembly 30 is also supported on the support part 41, so that the brush head assembly 30 is stably supported on the support frame 40; by providing an avoidance hole 415 on the first support section, it can not only avoid the water circuit switch 23, but also has a positioning function.

[0104] It is worth noting that the above embodiment describes that the first support section is provided with a clearance hole 415. In other embodiments, the clearance hole 415 may not be provided on the first support section. Instead, the length of the first support section along the length direction of the support section 41 may be reduced to avoid interference between the first support section and the water circuit switch 23.

[0105] In some embodiments, see Figure 6 The cross-section of the support part 41 is semi-circular to match the shape of the mounting section 34 on the brush head assembly 30.

Both the first top edge 413 and the second top edge 414 extend along the length direction of the support portion 41. See some examples. Figure 6 The first top edge 413 is turned outward in a direction away from the second top edge 414, and the second top edge 414 is turned outward in a direction away from the first top edge 413.

[0107] See some examples. Figure 6 The first top edge 413 includes a first top edge front section 4131 and a first top edge rear section 4132. The first top edge front section 4131 and the first top edge rear section 4132 are connected. The first top edge rear section 4132 is connected to the receiving part 42. The height of the first top edge front section 4131 is greater than the height of the first top edge rear section 4132.

[0108] In some examples, of the first top edge front section 4131 and the first top edge rear section 4132, only the first top edge front section 4131 is turned outward in a direction away from the second top edge 414; or, both the first top edge front section 4131 and the first top edge rear section 4132 may be turned outward in a direction away from the second top edge 414.

[0109] In some examples, the second top edge 414 includes a second top edge front section 4141 and a second top edge rear section 4142, the second top edge front section 4141 and the second top edge rear section 4142 are connected, the second top edge rear section 4142 is connected to the receiving part 42, and the height of the second top edge front section 4141 is greater than the height of the second top edge rear section 4142.

[0110] In some examples, in the second top edge front section 4141 and the second top edge rear section 4142, only the second top edge front section 4141 is turned outward in a direction away from the first top edge 413; or, the second top edge front section 4141 and the second top edge rear section 4142 can both be turned outward in a direction away from the first top edge 413.
