Description

Technical Field

[0001] This utility model relates to the field of scraper technology, and in particular to a scraper, brush head device and cleaning equipment. Background Technology

[0002] Currently, with the improvement of living standards, consumers' demand for home cleaning equipment is increasing. Cleaning equipment includes handheld and non-handheld cleaning equipment. Among them, handheld cleaning equipment is usually small in size and flexible in application, and is used in scenarios such as wall cleaning and kitchen cleaning.

[0003] In related technologies, most cleaning equipment is only compatible with a single squeegee, or uses a brush head device that combines a squeegee and a roller brush head. In certain complex cleaning scenarios, the cleaning effect is not good. For example, when the surface of the target to be cleaned is uneven, has a large slope, or has a tricky angle, the squeegee and the brush head cannot move relative to each other, so the squeegee or the brush head cannot simultaneously adhere to the surface to be cleaned. In other words, it is impossible to perform brushing and swiping actions at the same time, resulting in poor cleaning effect. Utility Model Content

[0053] It is understood that descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0054] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0055] In this embodiment of the application, the first direction is the direction corresponding to the X-axis, the second direction is the direction corresponding to the Y-axis, and the third direction is the direction corresponding to the Z-axis, as an example for explanation.

[0056] Please see Figure 1 , Figure 1 This is a three-dimensional structural diagram of the cleaning equipment 1000 provided by this utility model.

[0057] like Figure 1As shown, the cleaning device 1000 includes a brush head assembly 100, a first liquid storage tank 200, a separation tank 300, a second liquid storage tank 400, and a main unit 500. The brush head assembly 100 can be connected to at least one of the first liquid storage tank 200, the separation tank 300, and the second liquid storage tank 400, and is also connected to the main unit 500. It can be used to perform cleaning operations on the target object, including at least one of brushing, scraping, and wastewater recovery. The first liquid storage tank 200 is used to supply cleaning water to the brush head assembly 100. The separation tank 300 is connected to the brush head assembly 100 and the main unit 500, and is used to separate wastewater, dust, and other impurities generated during the cleaning process of the brush head assembly 100 on the target object. The separated wastewater can be stored in the second liquid storage tank 400, and the separated dust can be stored in the dust recovery component of the separation tank 300, such as on a filter screen or filter element structure installed inside the separation tank 300. The main unit 500 provides power for the brush head device 100 to perform cleaning operations and for the separation chamber 300 to perform separation operations.

[0058] The first liquid storage tank 200 can be connected to at least one of the separation tank 300, the brush head device 100 and the main unit 500; the second liquid storage tank 400 can be connected to at least one of the separation tank 300, the first liquid storage tank 200, the brush head device 100 and the main unit 500; and the main unit 500 is connected to at least one of the first liquid storage tank 200, the separation tank 300 and the second liquid storage tank 400.

[0059] For example, the first liquid storage tank 200, the separation tank 300, and the second liquid storage tank 400 are stacked vertically and connected to the main unit 500, respectively, and the brush head device 100 is connected to the separation tank 300. When the main unit 500 is started, the first liquid storage tank 200 sprays cleaning water onto the target to be cleaned through the brush head device 100. The brush head device 100 performs a brushing and scraping action while collecting the generated wastewater. The wastewater is separated by the separation tank 300 and then stored in the second liquid storage tank 400.

[0060] It is understood that the first liquid storage tank 200 and the second liquid storage tank 400 can be set on the same floor as the separation tank 300, and no restrictions are imposed here.

[0061] In some embodiments, the main unit 500 may include a gripping housing and a negative pressure device. The gripping housing may form a gripping part and an air outlet part. The air outlet part may be used to house the negative pressure device, which generates a suction airflow when it is working. This suction airflow creates negative pressure within the cleaning device 1000, thereby achieving the function of suction cleaning. The negative pressure device may be a fan.

[0062] In some embodiments, the main unit 500 may further include a power supply device and an electronic control device. The power supply device may include a power source, and the electronic control device may include a display screen, buttons, triggers, switches, or a touchscreen. The negative pressure device, electronic control device, and power supply device may be electrically connected to the brush head assembly 100 and the separation chamber 300.

[0063] In some embodiments, a water pump device may be disposed within the grip portion for pumping cleaning water from the first liquid reservoir 200 to the brush head device 100.

[0064] In some embodiments, the cleaning device 1000 further includes a third liquid reservoir for storing cleaning agent, and the pump device further includes a peristaltic pump, which may be disposed in the air outlet for pumping the cleaning agent in the third liquid reservoir to the brush head device 100.

[0065] Please see Figures 2a to 2b In some embodiments, the brush head device 100 includes a scraper 20, a brush head component 40, and a brush head connecting seat 50. The scraper 20 includes a plurality of suction ports 211 and is slidably connected to the brush head component 40 for performing a scraping action on the target to be cleaned and for collecting wastewater. The brush head component 40 includes a cleaning brush assembly 30 and a drive mechanism 10, and the brush head component 40 is slidably connected to the brush head connecting seat 50 and connected to the main unit 500 of the cleaning device 1000 through the brush head connecting seat 50. The drive mechanism 10 is connected to the cleaning brush assembly 30 and is used to drive the cleaning brush assembly 30 to perform a brushing action on the target to be cleaned. Under the action of external force, the scraper 20 can be relatively displaced relative to the brush head component 40 in a second direction.

[0066] The first liquid storage chamber 200, the separation chamber 300, and the second liquid storage chamber 400 are connected to the brush head component 40 and / or the scraper 20.

[0067] It is understandable that the brush head connector 50 can be detachably connected to the separation chamber 300 through structural engagement, threaded connection, or other means, or it can be integrally formed with the shell of the separation chamber 300; no limitation is made here.

[0068] Please see Figures 2b to 4 The scraper 20 is adapted to the brush head component 40 of the cleaning equipment 1000. The brush head component 40 is provided with a first connecting structure 25. The scraper 20 includes a scraping component 21 and a main body component 24.

[0069] The scraping component 21 is a flexible scraping component 21, and the scraping component 21 has at least a plurality of water inlets 211 arranged along a first direction, the first direction being the extension direction of the scraping component 21.

[0070] The main body component 24 is connected to the scraping component 21, forming a water suction channel 212 that communicates with the water suction port 211. The main body component 24 is also provided with a second connecting structure 26, through which the scraper 20 is slidably connected to the first connecting structure 25 in a second direction.

[0071] After the scraper 20 and the brush head component 40 are adapted and connected, the side of the brush head component 40 near the scraper 20 where the water inlet 211 is provided, and under the action of external force, the scraper 20 can be relatively displaced relative to the brush head component 40 in the second direction.

[0072] For example, in a three-dimensional space cleaning scenario, such as cleaning oil stains on a kitchen wall, the scraper 20 and the brush head component 40 are adapted and connected for use. When the brush head component 40 performs a scrubbing operation on the wall, the scraper 20 can be relatively displaced relative to the brush head component 40 in a second direction, which facilitates the scraping and collection of the cross-flowing sewage, realizing a closed-loop operation of scrubbing, scraping and sewage collection.

[0073] In this embodiment, the scraper 20 has a connection structure that is adapted to the brush head component 40 of the cleaning device 1000, which enables the scraper 20 and the brush head to be used together, avoiding the hassle of purchasing and storing additional brush head tools.

[0074] like Figure 3 As shown, in some embodiments, the first connecting structure 25 includes a first sliding member 251, which is disposed on the side of the brush head member 40 near the main body member 24.

[0075] The second connection structure 26 includes a first sliding groove 261, which is disposed on the side of the main body component 24 near the brush head component 40, and the first sliding component 251 is slidably connected to the first sliding groove 261.

[0076] Under the action of external force, the first sliding component 251 can be relatively displaced relative to the first sliding groove 261 in the second direction, so that the scraper 20 can be relatively displaced relative to the brush head component 40 in the second direction.

[0077] In this embodiment, by providing the first sliding groove 261, the scraper 20 and the brush head component 40 are connected by a sliding connection structure, eliminating the need for additional connectors and simplifying the assembly process.

[0078] In some embodiments, the second connecting structure 26 further includes a first link 264 and a second link 265, which are respectively disposed on opposite sides of the main body component 24 in the second direction and are used to slidably engage with the brush head component 40.

[0079] In this embodiment, the first connecting rod 264 and the second connecting rod 265 are disposed on opposite sides of the main body component 24 and are slidably connected to the brush head connecting seat 50, respectively. They have a guiding function in the second direction, making the displacement of the scraper 20 relative to the brush head component 40 in the second direction more stable. Furthermore, the second connecting structure 26 may also include an elastic component, which is disposed between the first connecting rod 264 and the brush head connecting seat 50, and between the second connecting rod 265 and the brush head connecting seat 50, so that the first connecting rod 264 and the second connecting rod 265 can elastically displace relative to the brush head component 40.

[0080] In some embodiments, the brush head connector 50 further includes a second sliding groove 267, and the second connecting structure 26 further includes a second sliding member 266. The second sliding member 266 is disposed on the side of the scraper 20 away from the brush head member 40 and is slidably connected to the second sliding groove 267. That is, when the scraper 20 is displaced relative to the brush head member 40 in the second direction, the second sliding member 266 can simultaneously be displaced relative to the second sliding groove 267 in the second direction.

[0081] like Figure 4 As shown, in some embodiments, the first sliding groove 261 includes a first sub-sliding groove 262 and a second sub-sliding groove 263. The first sub-sliding groove 262 is located on the side of the main body component 24 closer to the scraping component 21, and the second sub-sliding groove 263 is located on the side of the main body component 24 away from the scraping component 21.

[0082] The diameter of the first sub-sliding groove 262 in the first direction is smaller than the diameter of the second sub-sliding groove 263 in the first direction.

[0083] In this embodiment, a first sliding groove 261 is formed by connecting two first sub-sliding grooves 262 and second sub-sliding grooves 263 with different diameters. The second sub-sliding groove 263 with a larger diameter has a positioning and guiding function, which facilitates quick connection with the first sliding component 251. The first sub-sliding groove 262 with a smaller diameter can limit the sliding range of the first sliding component 251.

[0084] Please see Figure 5 In some embodiments, the scraping member 21 has a scraping part 213 and a drainage groove 214 on the side away from the main body member 24, and at least some of the suction ports 211 are connected to the drainage groove 214.

[0085] In this embodiment, by setting up the diversion channel 214, sewage can be collected and diverted to the suction port 211, which facilitates sewage recycling.

[0086] In some implementations, the water intake 211 and the diversion channel 214 are arranged in a one-to-one correspondence to improve the sewage collection effect.

[0087] like Figure 5 As shown, in some embodiments, the scraping part 213 forms a scraping plane 215 on the side near the drainage groove 214. During the scraping action of the scraper 20 on the target object, the scraping plane 215 forms surface contact with the target object.

[0088] In this embodiment, the scraping part 213 forms a scraping plane 215 with surface contact with the surface to be cleaned, which increases the scraping area and improves the water scraping effect.

[0089] Please see 5 and Figure 6 In some embodiments, the drainage groove 214 is arc-shaped, or the groove spacing of the drainage groove 214 gradually increases from the side closer to the main body component 24 to the side farther away from the main body component 24.

[0090] In this embodiment, the design of gradually increasing arc-shaped grooves can significantly improve the efficiency of fluid transport, thereby improving the liquid diversion effect.

[0091] Please see Figures 6 to 8 In some embodiments, the scraping component 21 includes a first scraping member 22 and a second scraping member 23. The first scraping member 22 includes a first connecting end 221, a first free end 222 and a first adapter surface 223. The second scraping member 23 includes a second connecting end 231, a second free end 232 and a second adapter surface 233. The first connecting end 221 of the first scraping member 22 and the second connecting end 231 of the second scraping member 23 are used to connect with the main body component 24.

[0092] Wherein, after the first scraping member 22 and the second scraping member 23 are connected to the main body component 24, the first adapter surface 223 of the first scraping member 22 and the second adapter surface 233 of the second scraping member 23 are in contact, and there is a first gap between the first free end 222 and the second free end 232 in the second direction, so that the scraping member 21 forms a scraping part 213, and at least part of the drainage groove 214 is formed at the second free end 232 of the second scraping member 23.

[0093] The suction port 211 is formed between the first scraper 22 and the second scraper 23, or the suction port 211 is formed in at least one of the first scraper 22 and the second scraper 23.

[0094] After the scraper 20 and the brush head component 40 are adapted and connected, the second scraper 23 is located on the side of the scraper 20 near the brush head component 40.

[0095] In this embodiment, there is a first distance D1 between the first free end 222 of the first scraper 22 and the second free end 232 of the second scraper 23 in the second direction. This arrangement does not affect the scraping part 213 from scraping the surface to be cleaned, nor does it cause the second free end 232 with the drainage groove 214 to wear due to frequent scraping actions, while leaving a water absorption gap to ensure the water absorption effect.

[0096] In some embodiments, the second free end 232 of the second scraper 23 is formed with a plurality of drainage grooves 214, and the drainage grooves 214 are spaced apart along the first direction.

[0097] In this embodiment, the spaced arrangement of the diversion channels 214 can improve the efficiency of diverting fluid.

[0098] like Figure 7 As shown, in some embodiments, the scraping member 21 further includes a plurality of spaced-apart support ribs 27 for supporting and forming a water intake port 211, wherein the support ribs 27 are disposed on the first adapter surface 223 of the first scraping member 22. Optionally, the support ribs 27 may also be disposed on the second adapter surface 233 of the second scraping member 23. Alternatively, the support ribs 27 may be disposed on the first adapter surface 223 of the first scraping member 22 and the second adapter surface 233 of the second scraping member 23.

[0099] In this embodiment, the support rib 27 prevents the water inlet 211 from being closed, ensuring a smooth water absorption process.

[0100] In some embodiments, the end of the second scraper 23 away from the main body 24 is wedge-shaped or arc-shaped to better contact the surface of the target to be cleaned and improve the scraping effect of the scraper 20.

[0101] Please see Figure 8 and Figure 9 In some embodiments, both the first scraper 22 and the second scraper 23 are provided with a connecting part 217, and the main body component 24 is provided with a fixing part 216.

[0102] The connecting part 217 is disposed at the first connecting end 221 of the first scraping member 22 and the second connecting end 231 of the second scraping member 23, and the fixing part 216 is disposed at the end of the main body component 24 near the scraping member 21. The connecting part 217 and the fixing part 216 are adapted to be connected.

[0103] It is understood that the connecting part 217 or the fixing part 216 can be a protrusion or a recessed hole that matches the protrusion. When the connecting part 217 is a protrusion, the fixing part 216 is a recessed hole, and when the connecting part 217 is a recessed hole, the fixing part 216 is a protrusion.

[0104] In this embodiment, the main body component 24 is provided with a fixing part 216, which is a protrusion. The scraping component 21 is provided with a connecting part 217 that is adapted to the fixing part 216. The connecting part 217 is a concave hole, thereby assembling the scraping component 21 and the main body component 24 to form a scraper 20. The assembly method is simple and makes it easier to assemble the scraping component 21 and the main body component 24 with different material requirements.

[0105] In some embodiments, the scraping component 21 and the main body component 24 of the scraper 20 are designed as a single silicone injection molded unit, which can save process steps in the production process, improve production efficiency, and is more suitable for mass production.

[0106] Please see Figure 10 In some embodiments, the scraper 20 is further provided with a water outlet 218, which is located at the first free end 222 of the first scraper 22. Optionally, the water outlet 218 is located at the first free end 222 of the second scraper 23. Optionally, the water outlet 218 is located on the side of the main body component 24 near the brush head component 40.

[0107] It is understandable that the outlet 218, the inlet 211, and the suction channel 212 are located in a way that does not interfere with each other.

[0108] In this embodiment, the water outlet 218 is located on the side of the main body component 24 near the brush head component 40, eliminating the need for a separate nozzle for connection, reducing assembly steps, and making the space design more reasonable.
