Abstract
Description
Technical Field
[0001] This disclosure relates to the field of cleaning equipment, and more particularly to a cleaning device, a liquid storage tank, and a cleaning system. Background Technology
[0002] Currently, more and more families are choosing to use floor scrubbers for indoor cleaning. During operation, these scrubbers require a wastewater tank to collect trash and wastewater. This tank often has a handle for easy access. For aesthetic reasons and to prevent the handle from interfering with the floor when the scrubber is lying down, most wastewater tank handles are recessed into the tank's interior space and do not protrude from its outline.
[0003] However, the current handle design takes up a lot of space in the sewage tank and increases the difficulty of molding the sewage tank as a whole, which will lead to reduced structural stability and increased production costs. Summary of the Invention
[0004] This disclosure provides a cleaning device, a liquid storage tank, and a cleaning system, aiming to solve the technical problems of the large space occupied by the handle of the liquid storage tank in the cleaning device and the difficulty of integral molding of the liquid storage tank.
[0005] In a first aspect, embodiments of this disclosure provide a cleaning device, including:
[0006] Equipment body, and
[0007] A liquid reservoir, detachably mounted on the equipment body, for storing at least a portion of the dirt collected by the cleaning equipment during cleaning of the surface to be cleaned, the liquid reservoir comprising:
[0008] The box has a cavity for storing dirt, and at least a portion of the outer surface of the box is recessed toward the cavity to form a storage groove.
[0009] A handle connector is located on the outer surface of the box and outside the storage slot; and
[0010] The handle is movably connected to the handle connector and can move relative to the box to switch between a folded state and an unfolded state.
[0011] In the folded state, at least a portion of the handle is housed in the storage slot, and a fitting gap is formed between the handle and the box body.
[0012] In some embodiments, at least a portion of the projection of the handle onto the horizontal plane is located outside the projection range of the box onto the horizontal plane, at least in the unfolded state.
[0013] In some embodiments, the handle connector has a first rotatable connection portion, and the handle has a second rotatable connection portion that is rotatably connected to the first rotatable connection portion. Through the rotatable connection of the first rotatable connection portion and the second rotatable connection portion, the handle can rotate relative to the box body to switch between a folded state and an unfolded state.
[0014] In some embodiments, the first rotating connecting part and the second rotating connecting part are respectively a connecting shaft and a connecting hole that mates with the connecting shaft.
[0015] In some embodiments, the reservoir also includes a limiting member that is detachably connected to one end of the connecting shaft that extends out of the connecting hole, so as to limit the handle in the extending direction of the connecting shaft.
[0016] In some embodiments, the liquid storage tank also includes an elastic element connected to the handle connector and the handle, wherein the elastic element deforms and stores energy when the handle switches to the unfolded state under the action of an external force.
[0017] Furthermore, when the external force is removed, the elastic element releases its stored energy and applies force to the handle to switch the handle to the folded state.
[0018] In some embodiments, the handle connector or the box body is provided with a first limiting sub-part and a second limiting sub-part. In the folded state, the handle abuts against the second limiting sub-part, and in the unfolded state, the handle abuts against the first limiting sub-part.
[0019] In some embodiments, the number of handle connectors is at least two, and two of the at least two handle connectors are disposed outside the opposite sides of the storage slot and are movably connected to the handle.
[0020] Secondly, this disclosure also provides a liquid storage tank for use in cleaning equipment, the liquid storage tank comprising:
[0021] The housing has a receiving cavity for storing at least a portion of the dirt collected by the cleaning equipment when cleaning the surface to be cleaned, and at least a portion of the outer surface of the housing is recessed toward the receiving cavity to form a storage groove.
[0022] A handle connector is located on the outer surface of the box and outside the storage slot; and
[0023] The handle is movably connected to the box body via a handle connector and can move relative to the main body to switch between a folded state and an unfolded state.
[0024] In the folded state, at least a portion of the handle is housed in the storage slot, and a fitting gap is formed between the handle and the box body.
[0025] Thirdly, embodiments of this disclosure also provide a cleaning system, comprising:
[0026] Clean base stations; and
[0027] The cleaning device provided in any embodiment of this disclosure may optionally interface with a cleaning base station.
[0028] In summary, the present disclosure provides a cleaning device, a liquid storage tank, and a cleaning system. The cleaning device includes: a device body and a liquid storage tank. The liquid storage tank is detachably installed on the device body and is used to store at least a portion of the dirt collected by the cleaning device when cleaning a surface to be cleaned. The liquid storage tank includes: a housing with a cavity for storing dirt, and at least a portion of the outer surface of the housing is recessed towards the cavity to form a storage groove; a handle connector disposed on the outer surface of the housing and located outside the storage groove; and a handle movably connected to the handle connector and movable relative to the housing to switch between a folded state and an unfolded state. In the folded state, at least a portion of the handle is received in the storage groove, and a fitting gap is formed between the handle and the housing. The solution provided in this disclosure reduces the space occupied by the handle and handle connector on the liquid storage tank by placing the handle connector on the outer surface of the tank and outside the storage slot. It also reduces the difficulty and production cost of integral molding of the liquid storage tank, improves the structural stability of the liquid storage tank, and provides a storage slot to facilitate the user to apply force to the handle to switch the handle from a folded state to an unfolded state, thereby enabling the liquid storage tank to be picked up and put down through the handle.

Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. Based on the embodiments of this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

Figure 6 This is a partial structural diagram of the liquid storage tank in the cleaning equipment provided in this embodiment.
[0046] like Figure 1 As shown, one or more embodiments of this disclosure provide a cleaning device 101 for cleaning surfaces to be cleaned. The cleaning device 101 includes, but is not limited to, cleaning robots, floor scrubbers, vacuum cleaners, etc. For example, the cleaning device 101 can be a passive cleaning device 101, such as a handheld floor scrubber, or an active cleaning device 101, such as a robot vacuum cleaner. Surfaces to be cleaned include, but are not limited to, floors, roofs, tabletops, doors, windows, etc.
[0047] In this embodiment of the disclosure, the cleaning device 101 is a handheld floor scrubber as an example for specific description. Users can use the floor scrubber to clean the surface to be cleaned in the place where cleaning is required. However, it is obvious that the scope of protection of the cleaning device 101 in this disclosure is not limited to the handheld floor scrubber.
[0048] See Figures 2 to 5 Specifically, the cleaning equipment 101 includes a device body 10 and a liquid storage tank 20. The liquid storage tank 20 is detachably installed on the device body 10 and is used to store at least a portion of the dirt collected by the cleaning equipment 101 when cleaning the surface to be cleaned. Users can remove the liquid storage tank 20 from the device body 10 for operations such as draining and cleaning, or they can install the liquid storage tank 20 on the device body 10.
[0049] To further explain, the device body 10 is provided with at least one cleaning component 11, which is used to perform cleaning actions on the surface to be cleaned. For example, the cleaning component 11 includes at least one of a mop, a roller brush, and a scraper. A liquid storage tank 20 is correspondingly provided with the cleaning component 11 and is configured to collect at least a portion of the dirt generated during and / or after the cleaning process. For example, the cleaning component 11 is a roller brush rotatably mounted on the device body 10. When the cleaning device 101 cleans the surface to be cleaned, the roller brush contacts the surface and lifts up the dirt by rotating. The dirt collected during this process is temporarily stored in the liquid storage tank 20 through a suction pipe located in the device body 10 and connected to the liquid storage tank 20. It is understood that during the process of the dirt being suctioned into the liquid storage tank 20, some dirt may remain in the suction pipe.
[0050] The liquid storage tank 20 is described in detail as follows: The liquid storage tank 20 includes a tank body 21, a handle connector 22, and a handle 23. The tank body 21 has a accommodating cavity 211 for storing dirt. At least a portion of the outer surface of the tank body 21 is recessed towards the accommodating cavity 211 to form a storage groove 212. The handle connector 22 is disposed on the outer surface of the tank body 21 and is located outside the storage groove 212. The handle 23 is movably connected to the handle connector 22 and can move relative to the tank body 21 to switch between a folded state and an unfolded state. In the folded state, at least a portion of the handle 23 is received in the storage groove 212, and a fitting gap 26 is formed between the handle 23 and the tank body 21.
[0051] See Figure 5 First, let's describe the unfolded state: When the handle 23 is in the unfolded state, at least a portion of the handle 23 is outside the storage slot 212. The user can use the handle 23 to retrieve and place the liquid storage tank 20. Specifically, the user can grasp the handle 23 to lift the liquid storage tank 20. For example, along... Figure 5 As shown by the dotted line, the user can insert their fingers to hook the handle 23 and lift the liquid tank 20 upwards, thereby removing the liquid tank 20 from the device body 10. In addition, the user can grip the liquid tank 20 through the handle 23 when emptying the dirt from the liquid tank 20 or cleaning the liquid tank 20.
[0052] For example, by using the handle 23, the user can conveniently perform at least one of the following operations: remove the liquid storage tank 20 from a preset position in the cleaning device 101; place the liquid storage tank 20 into a preset position in the cleaning device 101 so that the liquid storage tank 20 is installed on the device body 10.
[0053] See Figure 2 and Figure 4Then, the retracted state is explained: When the handle 23 is in the retracted state, at least a portion of the handle 23 is housed within the storage groove 212. When the handle 23 switches from the unfolded state to the retracted state, the volume of the handle 23 housed within the storage groove 212 increases, and the volume exposed outside the storage groove 212 decreases. This is to prevent interference between the liquid storage tank 20 and the surface to be cleaned, which would affect the cleaning effect, when the cleaning device 101 performs lying-down cleaning, and to improve the overall aesthetics of the liquid storage tank 20.
[0054] For example, the device body 10 also includes a handle 30. The user operates the cleaning device 101 by holding the handle 30 to perform cleaning tasks. When cleaning low areas such as under sofas or beds, the user can perform a lying-down cleaning method, that is, lay the handle 30 down towards the surface to be cleaned, and then push the cleaning device 101 into the low area. Therefore, the closer the handle 30 is to the surface to be cleaned, the easier it is for the cleaning device 101 to clean a farther area, and the closer the liquid tank 20 is to the surface to be cleaned. The less the handle 23 protrudes beyond the housing 21, the less likely it is to interfere with the surface to be cleaned. For example, when the handle 30 is nearly parallel to the surface to be cleaned, the more the handle 23 protrudes beyond the storage slot 212, the more likely it is to interfere with the surface to be cleaned.
[0055] It should be noted that in the relevant technology, the handle connector 22 is set inside the storage slot 212, which means that more space needs to be reserved in the storage slot 212 to accommodate the handle 23, and also to accommodate the handle connector 22. This makes the storage slot 212 occupy a large volume of the box body 21. Correspondingly, the volume that the storage cavity 211 used to store dirt is reduced, and it also makes the integral molding of the liquid storage tank 20 more difficult and the production cost higher.
[0056] like Figures 2 to 6 As shown, the solution provided in this disclosure places the handle connector 22 on the outer surface of the housing 21, outside the storage slot 212. This eliminates the need to reserve space in the storage slot 212 to accommodate the handle connector 22, minimizing the space occupied by the storage slot 212. Furthermore, since the handle 23 is movably connected to the handle connector 22, the space reserved for the handle 23 in the storage slot 212 is also smaller. Therefore, the space occupied by the handle connector 22 and the handle 23 on the liquid storage tank 20 is significantly reduced compared to solutions in related technologies. This also reduces the difficulty and production cost of integral molding of the liquid storage tank 20, and improves the structural stability of the liquid storage tank 20.
[0057] In some embodiments, at least a portion of the projection of the handle 23 onto the horizontal plane is located outside the projection range of the box 21 onto the horizontal plane, at least in the unfolded state.
[0058] like Figures 2 to 6 As shown, for example, the outer contour of the box 21 is generally cylindrical and at least partially hollow. The accommodating cavity 211 is formed in the middle of the box 21. The storage groove 212 is formed by recessing one outer surface of the box 21 in the circumferential direction toward the middle of the box 21. Correspondingly, the projection range of the box 21 in the horizontal plane can be circular, elliptical or other shapes similar to a circle.
[0059] Specifically, in the unfolded state, at least a portion of the projection of the handle 23 onto the horizontal plane lies outside the projection range of the box 21 onto the horizontal plane. In the folded state, the entire projection of the handle 23 onto the horizontal plane lies within the projection range of the box 21 onto the horizontal plane; or, a portion of the projection of the handle 23 onto the horizontal plane lies within the projection range of the box 21 onto the horizontal plane, while another portion of the projection of the handle 23 onto the horizontal plane lies outside the projection range of the box 21 onto the horizontal plane.
[0060] It should be noted that, in order to ensure that the liquid storage tank 20 does not interfere with the surface to be cleaned as much as possible when the cleaning equipment 101 is performing lying-down cleaning, the portion of the projection of the handle 23 in the horizontal plane in the folded state that is outside the projection range of the box body 21 in the horizontal plane can be minimized.
[0061] For example, on a horizontal plane, the area of the handle 23 projected outside the projection range of the box 21 in the unfolded state is greater than the area of the handle 23 projected outside the projection range of the box 21 in the folded state.
[0062] On the one hand, since at least part of the projection of the handle 23 on the horizontal plane is outside the projection range of the box 21 on the horizontal plane when it is unfolded, the user can easily take out and put in the liquid storage tank 20 through the handle 23; on the other hand, in the folded state, the area outside the projection range of the handle 23 on the horizontal plane is reduced compared with the unfolded state, avoiding interference between the liquid storage tank 20 and the surface to be cleaned, and improving the overall aesthetics of the liquid storage tank 20.
[0063] Please see Figures 7 to 8 , Figure 7 This is a schematic diagram of another embodiment of the cleaning equipment provided in this disclosure. Figure 8 This is an exploded structural diagram of the liquid storage tank in the cleaning equipment provided in this embodiment.
[0064] like Figures 7 to 8 As shown, in some embodiments, the handle connector 22 has a first rotating connection portion 221, and the handle 23 has a second rotating connection portion 231 that is rotatably connected to the first rotating connection portion 221. Through the rotatable connection of the first rotating connection portion 221 and the second rotating connection portion 231, the handle 23 can rotate relative to the box 21 to switch between a folded state and an unfolded state.
[0065] Specifically, when the first rotating connecting part 221 and the second rotating connecting part 231 are rotatably engaged, the handle 23 can rotate relative to the box body 21. Specifically, when the handle 23 rotates away from the box body 21, it switches from a folded state to an unfolded state; when the handle 23 rotates towards the box body 21, it switches from an unfolded state to a folded state. It can be understood that when the handle 23 rotates away from or towards the box body 21, it specifically refers to the end of the handle 23 opposite to the second rotating connecting part 231, or in other words, the end to which the user applies force, rotating away from or towards the box body 21.
[0066] Therefore, the handle 23 can be conveniently switched between the folded state and the unfolded state by the rotational engagement of the first rotating connecting part 221 and the second rotating connecting part 231.
[0067] In some embodiments, the first rotating connection portion 221 and the second rotating connection portion 231 are respectively a connecting shaft 222 and a connecting hole 232 that forms a shaft hole with the connecting shaft 222.
[0068] As one example, in such Figure 3 , Figure 5 and Figure 7 In the liquid storage tank shown, the first rotating connection part 221 formed on the handle connector 22 is a connecting shaft 222, and the second rotating connection part 231 formed on the handle 23 is a connecting hole 232. By cooperating with the shaft hole of the connecting shaft 222 and the connecting hole 232, the handle 23 can rotate relative to the tank body 21 to switch between the folded state and the unfolded state.
[0069] In another embodiment, the first rotating connection part 221 is a connecting hole 232, and the second rotating connection part 231 formed on the handle 23 is a connecting shaft 222. Similarly, by the connection shaft 222 cooperating with the shaft hole of the connecting hole 232, the handle 23 can rotate relative to the box 21 to switch between the folded state and the unfolded state.
[0070] See Figure 2 The fitting gap 26 is explained as follows: In the folded state, a fitting gap 26 with a certain width is formed between the handle 23 and the housing 21. For example, the fitting gap 26 can refer to the gap between the second rotating connection 231 and the first rotating connection 221. It should be understood that the fitting gap 26 provided between the handle 23 and the housing 21 facilitates the user's application of force to the handle 23 when it is in the folded state, allowing for movement during rotation so that the handle 23 can smoothly switch from the folded state to the unfolded state.
[0071] like Figure 8 As shown, in some embodiments, the liquid storage tank 20 further includes a limiting member 24, which is detachably connected to one end of the connecting shaft 222 that extends through the connecting hole 232, so as to limit the handle 23 in the extending direction of the connecting shaft 222.
[0072] Specifically, taking the first rotating connecting part 221 as the connecting shaft 222 and the second rotating connecting part 231 as the connecting hole 232 as an example, when the connecting shaft 222 passes through the connecting hole 232 and the limiting member 24 is connected to one end of the connecting shaft 222 that passes through the connecting hole 232, the handle connecting member 22 and the limiting member 24 are respectively located on opposite sides of the handle member 23 in the extension direction of the connecting shaft 222. This limits the handle member 23 in the extension direction of the connecting shaft 222, improves the stability of the structural connection between the handle member 23 and the handle connecting member 22 when the handle member 23 rotates relative to the box body 21, and reduces the possibility of the handle member 23 and the handle connecting member 22 detaching.
[0073] Furthermore, when the limiting member 24 is disconnected from the end of the connecting shaft 222 that protrudes from the connecting hole 232, the handle member 23 can be easily removed from the handle connector 22.
[0074] like Figure 7 As shown, in some embodiments, the liquid storage tank 20 further includes an elastic element 25 connected to the handle connector 22 and the handle 23. When the handle 23 switches to the unfolded state under the action of an external force (such as the force applied by the user), the elastic element 25 deforms and stores energy; and when the external force is removed, the elastic element 25 releases the stored energy and applies force to the handle 23 to switch the handle 23 to the retracted state.
[0075] Specifically, when the handle 23 is in the folded state, when the user applies an external force to the handle 23 away from the box 21, the handle 23 rotates relative to the box 21 to switch to the unfolded state. At the same time, the elastic element 25 deforms and stores energy under the compression of the handle 23 and the handle connector 22. When the user stops applying an external force to the handle 23 away from the box 21, the elastic element 25 releases its stored elastic energy and applies an external force to the handle 23 in the direction closer to the box 21. The handle 23 rotates relative to the box 21 to switch to the unfolded state until the handle 23 returns to the folded state.
[0076] For example, the elastic element 25 can be a torsion spring, one end of which is connected to the handle connector 22 and the other end is connected to the handle 23. When the handle 23 switches to the unfolded state under the action of an external force, the torsion spring undergoes torsional deformation and stores energy. When the external force is removed, the torsion spring releases the stored energy and applies force to the handle 23 to switch the handle 23 to the retracted state.
[0077] It should be understood that by setting the elastic element 25, during the daily use of the liquid storage tank 20, when the user removes the force applied to the handle 23, the handle 23 can automatically retract to the folded state, thereby reducing the area of the handle 23 projected onto the horizontal plane outside the projection range of the tank body 21, that is, reducing the volume of the handle 23 protruding beyond the tank body 21, so as to avoid interference between the liquid storage tank 20 and the surface to be cleaned when the cleaning equipment 101 performs lying-down cleaning, thus avoiding affecting the cleaning effect.
[0078] like Figure 7 As shown, the handle 23 is described below: The handle 23 includes a gripping portion 233 for holding and an adapter connecting portion 234 connected to the gripping portion 233, wherein a second rotating connecting portion 231 is formed in the adapter connecting portion 234. As one embodiment, at least two adapter connecting portions 234 are provided, and at least two adapter connecting portions 234 extend and are formed on the same side of the gripping portion 233, and are respectively connected and adapted to the handle connector 22.
[0079] For example, the width direction X of the grip portion 233 and the adapter connection portion 234 is the same as the rotation axis of the handle 23 relative to the second rotating connection portion 231, and the extension direction Y of the adapter connection portion 234 relative to the grip portion 233 is perpendicular to the rotation axis.
[0080] For example, the width a of the grip portion 233 is 50-70mm, the width b of each adapter connection portion 234 is 8-20mm, the length c of each adapter connection portion 234 extending relative to the grip portion 233 is 5-15mm, and the angle between the handle 21 and the grip portion 233 when switching between the folded and unfolded states is 15-35°. Alternatively, the width a of the grip portion 233 can be set to 60-65mm, the width b of each adapter connection portion 234 can be set to 12-16mm, the length c of each adapter connection portion 234 extending relative to the grip portion 233 can be set to 8-12mm, and the angle between the handle 21 and the grip portion 234 when switching between the folded and unfolded states can be set to 20-30°.
[0081] Therefore, the above settings can provide a better grip experience for the handle 23 and make it easier to switch the handle 23 to the unfolded state.
[0082] In some embodiments, the handle connector 22 or the housing 21 is further provided with a first limiting sub-part 223, and the handle connector 22 or the housing 21 is further provided with a second limiting sub-part 213, the first limiting sub-part 223 and the second limiting sub-part 213 corresponding to the position of the adapting connecting part 234; for example, the first limiting sub-part 223 and the second limiting sub-part 213 are both provided on the outer surface of the housing 21; for another example, the first limiting sub-part 223 is provided on the handle connector 22, and the second limiting sub-part 213 is provided on the outer surface of the housing 21, wherein ... A limiting sub-part 223 can be integrally formed with the first rotating connecting part 221 to form a handle connector 22, or it can be separately formed with the first rotating connecting part 221 to form a handle connector 22. For example, both the first limiting sub-part 223 and the second limiting sub-part 213 can be provided on the handle connector 22, wherein the first limiting sub-part 223 and the second limiting sub-part 213 can be integrally formed with the first rotating connecting part 221 to form a handle connector 22, or they can be separately formed with the first rotating connecting part 221 to form a handle connector 22. The specific configuration can be selected according to the actual situation, and this disclosure does not impose specific limitations in this regard.
[0083] In the folded state, the handle 23 abuts against the second limiting sub-part 213, and in the unfolded state, the handle 23 abuts against the first limiting sub-part 223. For example, the second limiting sub-part 223 is provided with a limiting surface 2231, which is inclined relative to the Y direction (e.g., from the direction of the adapter connection 234 towards the grip 233, the limiting surface 2231 is inclined from the handle 23 towards the box body 21). In the unfolded state, the side of the adapter connection 234 facing the box body 21 abuts against the limiting surface 2231, and in the folded state, the side of the adapter connection 234 facing the box body 21 abuts against the side of the second limiting sub-part 213 facing the handle 23.
[0084] Specifically, when the handle 23 rotates towards the housing 21, it switches from an extended state to a retracted state. In the retracted state, the handle 23 abuts against the second limiting sub-part 213 to limit its rotation range. When the handle 23 rotates away from the housing 21, it switches from a retracted state to an extended state. In the extended state, the handle 23 abuts against the first limiting sub-part 223 to limit its rotation range, thereby improving the structural stability of the liquid storage tank 20.
[0085] In other embodiments, the connection between the handle connector 22 and the handle 23 can also be a sliding connection. For example, the handle connector 22 has a first guide connection portion, and the handle 23 has a second guide connection portion that is guided and connected to the first guide connection portion. Through the guiding connection of the first guide connection portion and the second guide connection portion, the handle 23 can slide relative to the box 21 to switch between a folded state and an unfolded state.
[0086] Specifically, when the first guide connection part and the second guide connection part are guided and engaged, the handle 23 can slide relative to the box 21. When the handle 23 slides away from the box 21, the handle 23 switches from a retracted state to an unfolded state. When the handle 23 slides towards the box 21, the handle 23 switches from an unfolded state to a retracted state.
[0087] Therefore, the handle 23 can be easily switched between the folded state and the unfolded state through the guiding cooperation of the first guide connection and the second guide connection.
[0088] In some embodiments, one of the first guide connecting portion and the second guide connecting portion is a groove, and the other is a slider that forms a guiding engagement with the groove.
[0089] In some embodiments, the number of handle connectors 22 is at least two, and two of the at least two handle connectors 22 are disposed outside the opposite sides of the storage slot 212 and are movably connected to the handle 23.
[0090] In one embodiment, there are two handle connectors 22, which are disposed on opposite sides of the storage groove 212 and are movably connected to the handle 23 respectively. For example, the outer contour of the box body 21 is generally cylindrical, the receiving cavity 211 is formed in the middle of the box body 21, and the storage groove 212 is formed by recessing one outer surface of the box body 21 in the circumferential direction towards the middle of the box body 21. Correspondingly, the two handle connectors 22 are also disposed in the circumferential direction of the box body 21. For example, the two handle connectors 22 are disposed on opposite sides of the storage groove 212 along direction X, and the handle 23 includes two adapter connecting portions 234 corresponding to the two handle connectors 22 respectively and a gripping portion 233 disposed between the two adapter connecting portions 234.
[0091] Based on the above configuration, the handle connectors 22 located on opposite sides of the storage slot 212 are movably connected to the handle 23, which improves the stability of the movable connection between the handle 23 and the handle connector 22 and reduces the possibility of the handle 23 disengaging from the handle connector 22 when it rotates relative to the box 21.
[0092] In some embodiments, the handle 23 is rotatable relative to the box 21, and two of the at least two handle connectors 22 are disposed on opposite sides of the storage slot 212 in a target direction, the target direction being the rotation axis of the handle 23 relative to the box 21.
[0093] It should be understood that the target direction is the rotational axis of the handle 23 relative to the housing 21, and also the extension direction of the connecting shaft 222. For example, the target direction can be horizontal or vertical. Figure 7 The direction X is shown in the diagram.
[0094] Based on the above configuration, the two handle connectors 22 improve the stability of the handle 23 when it rotates relative to the box 21, and reduce the possibility of the handle 23 detaching from the handle connector 22.
[0095] like Figures 1 to 8 As shown, one or more embodiments of this disclosure also provide a liquid storage tank 20, applied to a cleaning device 101, the liquid storage tank 20 comprising:
[0096] The housing 21 has a receiving cavity 211 for storing at least a portion of the dirt collected by the cleaning equipment 101 when cleaning the surface to be cleaned. At least a portion of the outer surface of the housing 21 is recessed in the direction of the receiving cavity 211 to form a storage groove 212.
[0097] Handle connector 22 is provided on the outer surface of the box body 21 and is located outside the storage slot 212; and
[0098] The handle 23 is movably connected to the box 21 via the handle connector 22 and can move relative to the main body to switch between a folded state and an unfolded state.
[0099] In the folded state, at least a portion of the handle 23 is housed in the storage slot 212, and a fitting gap 26 is formed between the handle 23 and the box body 21.
[0100] Specifically, when the handle 23 is in the unfolded state, at least a portion of the handle 23 is located outside the storage slot 212, and the user can use the handle 23 to take out and put in the liquid storage tank 20. For example, the user can grab the handle 23 to lift the liquid storage tank 20.
[0101] For example, by using the handle 23, the user can conveniently perform at least one of the following operations: remove the liquid storage tank 20 from a preset position in the cleaning device 101; place the liquid storage tank 20 into a preset position in the cleaning device 101 so that the liquid storage tank 20 is installed on the device body 10.
[0102] When the handle 23 is in the retracted state, at least a portion of the handle 23 is housed within the storage slot 212. When the handle 23 switches from the unfolded state to the retracted state, the volume of the handle 23 housed within the storage slot 212 increases, while the volume exposed outside the storage slot 212 decreases. This is to prevent interference between the liquid storage tank 20 and the surface to be cleaned, which would affect the cleaning effect, when the cleaning device 101 performs lying-down cleaning, and to improve the overall aesthetics of the liquid storage tank 20.
[0103] It should be noted that the liquid storage tank 20 provided in this embodiment can be referred to the specific description of the liquid storage tank 20 in the cleaning equipment 101 provided in the foregoing embodiment, and will not be repeated here.
[0104] Please see Figure 9 This is a schematic diagram of one embodiment of the cleaning system provided in this disclosure.
[0105] One or more embodiments of this disclosure also provide a cleaning system 100, which includes a cleaning device 101 and a cleaning base station 102, wherein the cleaning device 101 is the cleaning device 101 provided in any embodiment of this disclosure, and the cleaning device 101 can be selectively connected to the cleaning base station 102.
[0106] For example, when the cleaning device 101 is moved to or placed on the cleaning base station 102, the cleaning device 101 and the cleaning base station 102 are connected to facilitate the cleaning base station 102 to perform maintenance on the cleaning device 101. The types of maintenance include, but are not limited to, charging, dust collection, cleaning of cleaning components, replenishment of clean water, and pumping of wastewater.
[0107] Specifically, when the cleaning device 101 is connected to the cleaning base station 102, the cleaning base station 102 can perform at least one of the following maintenance operations: 1. The cleaning base station 102 charges the cleaning device 101; 2. The cleaning base station 102 collects debris (e.g., debris in the dust box or wastewater tank of the cleaning device 101) from the cleaning device 101 into its dust collection container; 3. The cleaning base station 102 cleans the cleaning components 33 of the cleaning device 101 (e.g., washes the mop, cleans the roller brush, washes the roller, etc.); 4. The cleaning base station 102 replenishes the clean water tank of the cleaning device 101 with clean water; 5. The cleaning base station 102 collects dirt from the wastewater tank of the cleaning device 101 into its wastewater container and discharges it to the outside. The above maintenance types are merely illustrative descriptions and are not intended to limit this disclosure.
[0108] In summary, this disclosure provides a cleaning device 101, a liquid storage tank 20, and a cleaning system 100. The cleaning device 101 includes a device body 10 and a liquid storage tank 20. The liquid storage tank 20 is detachably mounted on the device body 10 and is used to store at least a portion of the dirt collected by the cleaning device 101 when cleaning a surface to be cleaned. The liquid storage tank 20 includes a housing 21, which has a cavity 211 for storing dirt. At least a portion of the outer surface of the housing 21 faces the cavity 211. The cavity 211 is recessed to form a storage groove 212; a handle connector 22 is provided on the outer surface of the box 21 and located outside the storage groove 212; and a handle 23 is movably connected to the handle connector 22 and can move relative to the box 21 to switch between a folded state and an unfolded state; wherein, in the folded state, at least a portion of the handle 23 is received in the storage groove 212, and a fitting gap 26 is formed between the handle 23 and the box 21.
[0109] The solution provided in this disclosure reduces the space occupied by the handle 23 of the liquid storage tank 20 by setting the handle connector 22 on the outer surface of the box 21 and outside the storage slot 212, and reduces the difficulty and production cost of integral molding of the liquid storage tank 20, thereby improving the structural stability of the liquid storage tank 20. Moreover, the space provided by the storage slot 212 makes it convenient for the user to apply force to the handle 23 to switch the handle 23 from the folded state to the unfolded state, so as to realize the retrieval and placement of the liquid storage tank 20 through the handle 23.
