In an alternative embodiment of the invention, the cleaning device may comprise: the device comprises a device body, a sensing system, a control system, a driving system, a cleaning system, an energy system, a human-computer interaction system and the like. All the systems are coordinated with each other, so that the cleaning equipment can move autonomously to realize the cleaning function. Functional elements and the like constituting the above-described respective systems in the cleaning apparatus are integrally provided in the apparatus main body. The cleaning part of the cleaning system comprises a dry cleaning part and a wet cleaning part, so that the sweeping function and the mopping function are realized.

In some possible embodiments, as shown in fig. 1, fig. 2 and fig. 3, the base station further includes a float assembly 110, a non-contact sensing element 130 and a non-contact sensed element 140, wherein the float assembly 110 is disposed inside the water tank assembly 200 and includes a float body 111 capable of floating under the action of liquid, that is, the float body 111 floats up and down along with the rise or fall of the liquid surface, and the float body 111 can float on the liquid surface under the action of liquid. The non-contact sensing element 130 is used for detecting the non-contact sensed element 140, for example, the non-contact sensing element 130 is used for detecting the signal parameter emitted by the non-contact sensed element 140, one of the non-contact sensing element 130 and the non-contact sensed element 140 is arranged on the float body 111, and the other is arranged separately from the water tank assembly and is located on the base station body, that is, one of the non-contact sensing element 130 and the non-contact sensed element 140 moves along with the float body 111, and the other is arranged at a fixed position outside the water tank assembly 200, for example, the other is arranged at the position to be installed of the water tank assembly 200 on the base station body, so that the signal parameter emitted by the non-contact sensed element 140 detected by the non-contact sensing element 130 is different during the up-down floating of the float body 111 under the action of the liquid, the liquid level range within the tank assembly 200 may then be determined based on the different signal parameters and the current position of the tank assembly 200 determined. If the water tank assembly 200 is disposed on the base station body and the liquid surface in the water tank assembly 200 is at a specific position, the non-contact sensing element 130 can sense the signal parameter transmitted by the non-contact sensed element 140, which indicates that the water tank assembly 200 is correctly mounted on the base station body and the liquid surface in the water tank assembly 200 reaches the specific position, i.e. one set of the detecting devices such as the float assembly 110, the non-contact sensing element 130 and the non-contact sensed element 140 can simultaneously detect the liquid level in the water tank assembly 200 and the current position of the water tank assembly 200, compared with the related art in which the liquid level detecting device can only detect the liquid level in the water tank assembly 200 and cannot detect the current position of the water tank assembly 200, the function of the float assembly 110 is expanded, and compared with the related art in which two sets of detecting devices are used to detect the liquid level in the water tank assembly 200 and the current position of the water tank assembly 200, the device simplifies the arrangement of a set of detection devices, namely, the structure of a product, and simplifies system software programs and algorithms, can effectively save cost, and is suitable for popularization and application.

Further, on the one hand, the non-contact sensed element 140 is provided on the float body 111 and the non-contact sensed element 130 is provided on the base station body, and on the other hand, the non-contact sensed element 130 is provided on the float body 111 and the non-contact sensed element 140 is provided on the base station body. Different arrangement positions of the non-contact sensed element 140 and the non-contact sensing element 130 can meet the requirements of different structures and different performances of the non-contact sensed element 140 and the non-contact sensing element 130, and the application range of the product is expanded. It is understood that the non-contact sensed element 140 may include a magnetic element, a light emitting element, or other components as desired, and the non-contact sensing element 130 may include a magnetic sensing element, a light sensing element, or other components as desired. The non-contact sensed member 140 or the non-contact sensing member 130 disposed on the float body 111 may be located inside or outside the float body 111 or at other positions as required, and the present invention is not particularly limited.

Further, the water tank assembly 200 may be a clean water tank for containing cleaning liquid or a dirty water tank for containing dirty liquid, and the float body 111, the non-contact sensing element 130, and the non-contact sensed element 140 may be arranged at different positions due to different functions of the water tank assembly. For example, the liquid in the clean water tank is mainly used for cleaning the cleaning portion or supplying liquid to the liquid storage tank, that is, the liquid in the clean water tank is less and less in the working process, and therefore, it is required to ensure that a certain amount of liquid in the clean water tank can act on the cleaning portion and/or the liquid storage tank, that is, when the clean water tank is short of liquid needs to be detected. Therefore, the float body 111 can be arranged on the bottom wall or the side wall of the clean water tank, and one of the non-contact sensing element 130 and the non-contact sensed element 140 is arranged on the base station body and close to the bottom wall of the clean water tank, so that when the clean water tank assembly 200 is installed on the base station body and the liquid level in the clean water tank reaches a specific position, the non-contact sensed element 130 can sense the non-contact sensed element 140, which indicates that the clean water tank assembly 200 is correctly installed on the base station body and the liquid in the water tank assembly is less, and the liquid needs to be replenished in time.

For another example, the waste water tank is mainly used for collecting waste liquid during cleaning, that is, liquid in the waste water tank is increased during the operation of the cleaning device, and in order to avoid that the liquid in the waste water tank overflows to affect the reliability or cleaning effect of the cleaning device, it is required to detect when the waste water tank is full of liquid. Therefore, the float body 111 may be disposed on the top wall or the side wall of the clean water tank, and one of the non-contact sensing element 130 and the non-contact sensed element 140 is disposed on the base station body and close to the top wall of the clean water tank, so that when the clean water tank assembly 200 is mounted on the base station body and the liquid level in the clean water tank reaches a specific position, the non-contact sensed element 130 can sense the non-contact sensed element 140, which indicates that the clean water tank assembly 200 is correctly mounted on the base station body and the liquid in the clean water tank assembly 200 is full, and the liquid in the dirty water tank needs to be poured out in time.

In some possible implementations of the present invention, the non-contact sensed element 140 includes a magnetic member, and the non-contact sensing element 130 includes a hall sensor, such as a magnetic sensing member. Wherein, the magnetic part is arranged on the floater body 111, and the Hall sensor is arranged on the base station body. Specifically, the magnetic part can be arranged in the floater body 111, and by means of the arrangement, the problem that the magnetic part is corroded, caused by faults and interfered with signal emission intensity due to the fact that the magnetic part is arranged outside the floater body 111 and liquid wets the magnetic part can be avoided, and therefore the service life of the magnetic part and the stability and reliability of the emitted signals can be improved.

That is to say, in the base station provided by the embodiment of the present invention, the float assembly 110 is disposed inside the water tank assembly 200, the magnetic member is disposed inside the float body 111 located inside the water tank assembly 200, and the hall sensor is disposed on the base station body, when the magnetic member floats to the detection range of the hall sensor under the action of the liquid, it indicates that the liquid level inside the water tank assembly 200 reaches a specific height, and the water tank assembly 200 is correctly installed on the base station body, wherein the specific height may be 10mm, 20mm, 30mm, 50mm or other values or ranges meeting the requirements, and the correct installation of the water tank assembly 200 on the base station body may be a reliable and accurate connection between the water tank assembly 200 and the base station body.

It can be understood that the base station according to the embodiment of the present invention is provided with the float assembly 110 disposed inside the water tank assembly 200, and the magnetic member disposed inside the float body 111, the hall sensor is arranged on the base station body, and because the magnetic part floats along with the floater body 111, the position of the magnetic member and the float body 111 is fixed, the hall sensor can detect signals of different parameters emitted by the magnetic member, therefore, by reasonably setting the detection range of the Hall sensor, for example, the detection range can be a preset threshold value of the magnetic member emission signal received by the Hall sensor, when the signal parameter transmitted by the magnetic component and received by the hall sensor reaches the preset threshold value, the liquid level in the water tank component 200 reaches the designated height, and the water tank component 200 is correctly installed on the base station body, that is, the magnetic member can float to within the detection range of the hall sensor following the float body 111. Therefore, the positions of the magnetic part and the Hall sensor and the detection range of the Hall sensor are reasonably arranged, and the magnetic part and the Hall sensor are matched with the floater assembly 110, so that whether the liquid level in the water tank assembly 200 and the water tank assembly 200 are detected in place or not can be realized, the structure is simple, the realization is easy, the cost is lower, and the popularization and the application are suitable. Wherein, the detection range of the magnetic induction member is shown as P in fig. 2 and 3.

Specifically, the magnetic part may be a magnetic stripe, a magnetic ring or other magnetic structures meeting the requirements, and the hall sensor may be a magnetic induction sensor or other structures meeting the requirements, specifically, the magnetic induction sensor may be an annular structure or a sheet structure or other structures meeting the requirements.

Further, the number of the hall sensors can be one, two or more, the two or more hall sensors are arranged at different positions of the base station body, and the liquid surfaces with different heights in the water tank assembly 200 can be sensed to reach different specific positions, so that the liquid surfaces with different heights in the water tank assembly 200 can be detected, and the application range of the product is enlarged.

In some possible embodiments, the base station further includes a controller, and the non-contact sensing element 130 is electrically connected to the controller of the base station to output the sensing result to the controller. It will be appreciated that the controller of the base station may also interact with information of the cleaning robot or a remote control terminal (APP) or the like. Therefore, the controller can conveniently and reasonably control other parts of the cleaning system to work according to the sensing result of the non-contact sensing element 130, for example, the position of the water tank assembly 200 can be adjusted according to the sensing result so as to correctly install the water tank assembly 200 on the base station body, and liquid can be timely replenished to the water tank assembly 200 according to the sensing result, so that the liquid in the water tank assembly 200 can be reliably and fully acted on the cleaning part and/or the liquid storage tank, the cleaning equipment can also be controlled to stop working according to the sensing result, the phenomenon that more sewage in the water tank assembly 200 overflows is avoided, and the working reliability of the cleaning system is greatly improved.

In some embodiments, as shown in fig. 6, 7 and 8, the float assembly 110 further includes an installation frame 112 and a connection portion 113, the installation frame 112 is disposed inside the water tank assembly 200 and detachably connected to the water tank assembly 200, one end of the connection portion 113 is rotatably connected to the installation frame 112, and the other end is connected to the float body 111, that is, the float body 111 is under the action of liquid, the connection portion 113 can swing in an up-and-down direction with respect to the installation frame 112, that is, the connection portion 113 can swing in a direction close to the bottom wall of the water tank assembly 200 and in a direction far away from the bottom wall of the water tank assembly 200 with respect to the installation frame 112, and further, the magnetic member is driven to swing up and down with respect to the bottom wall of the water tank assembly 200.

Because the mounting bracket 112 is detachably connected with the water tank assembly 200, that is, the float assembly 110 can be assembled into different water tank assemblies 200 through the mounting bracket 112, and because the non-contact sensing element is detachably disposed on the base station body, the non-contact sensed element 130 can detect the liquid levels and the current positions in different water tank assemblies 200, that is, the float assembly, the non-contact sensed element 130, and the non-contact sensing element 140 can be regarded as a liquid level detection device as a whole, and can be configured in corresponding products or scenes as standardized modules, thereby expanding the application range of the liquid level detection device. Meanwhile, due to the arrangement of the mounting frame 112, a user can conveniently detach the floater assembly 110 from the water tank assembly 200 for maintenance and cleaning, and the use experience of the user is greatly improved.

Specifically, the mounting bracket 112 is provided with a through hole, the connecting portion 113 is provided with a mounting hole, the connecting portion 150 penetrates through the mounting hole and the through hole, the connecting portion 113 and the mounting bracket 112 can be rotatably connected, specifically, the connecting portion 150 is a rotating shaft, a hinge pin or other connecting portion 150 meeting requirements, the axis of the connecting portion 113 rotating relative to the mounting bracket 112 is parallel to the plane where the bottom wall of the water tank assembly 200 is located, for example, the axis of the rotating shaft is parallel to the plane where the bottom wall of the water tank assembly 200 is located, and thus, the connecting portion 113 can only swing in the vertical direction approximately relative to the mounting bracket 112.

Because the float body 111 floats under the action of the liquid and drives the connecting part 113 to rotate relative to the mounting frame 112, and simultaneously drives the magnetic component to swing along the vertical direction relative to the bottom wall of the water tank component 200, the limit part 114 is arranged on at least one of the mounting frame 112 and the connecting part 113, and the limit part 114 is utilized to limit the rotation range of the connecting part 113 relative to the mounting frame 112, so as to limit the swing of the magnetic component relative to the bottom wall of the water tank component 200 along the vertical direction, so that the liquid level in the water tank component 200 reaches the designated height, and when the water tank component 200 is installed on the base station body, the magnetic component can accurately and reliably float to the detection range of the hall sensor under the driving of the float body 111, namely the limit part 114 is arranged, so that when the liquid level in the water tank component 200 reaches the preset height and the water tank component 200 is installed on the base station body, the magnetic component can float to the detection range of the hall sensor, the liquid level detection in the water tank assembly 200 and the detection of whether the water tank assembly 200 is in place can be realized by utilizing the mutual matching of the group of Hall sensors, the magnetic component and the floater component, the accuracy and the reliability of a detection result are ensured, the structure is simple, the cost is lower, and the device is suitable for popularization and application.

It can be understood that the limiting portion 114 may be disposed on one of the mounting frame 112 or the connecting portion 113, or may be disposed on both the mounting frame 112 and the connecting portion 113, and different positions of the limiting portion 114 may meet different structural requirements of the limiting portion 114.

Further, spacing portion 114 is including setting up the baffle on mounting bracket 112, the baffle is located connecting portion 113's top, and be located between connecting portion 113's both ends, the baffle is located the one end that connecting portion 113 is connected with mounting bracket 112 and the other end that is connected with float body 111 between, such setting, make float body 111 float upwards under the effect of liquid and drive connecting portion 113 for mounting bracket 112 to the orientation wobbling in-process of keeping away from water tank subassembly 200 diapire, connecting portion 113 can with the baffle butt, float body 111 is behind with the baffle butt promptly, can not rise along with the liquid level increases and the come-up, only can sink along with the liquid level reduction. Because the magnetic part sets up the inside at float body 111, float the in-process at float body 111, the magnetic part is fixed unchangeable for float body 111's position, therefore, when connecting portion 113 and baffle butt, the magnetic part is fixed unchangeable for water tank set spare 200's position, so, the height definition of liquid level is appointed height when connecting portion 113 and baffle butt, under this state, rationally inject hall sensor's detection range, so that water tank set spare 200 correctly installs to waiting to install the structure after, the magnetic part is located hall sensor's detection range, and then through this hall sensor, both can detect the liquid level height in water tank set spare 200, can detect on the water tank set spare 200 correctly installs to waiting to install the structure again, moreover, the steam generator is simple in structure, and manufacturing cost is lower.

For example, the water tank assembly 200 in the embodiment of the present invention is a clean water tank, the water tank assembly 200 is applied to a base station of a cleaning system, the water tank assembly 200 is detachably mounted on a base station body, wherein, the Hall sensor is arranged on the base station body, the mounting bracket 112 of the float assembly 110 is fixed on the bottom wall of the water tank assembly 200, one end of the connecting part 113 is rotatably connected with the mounting bracket 112 through a rotating shaft, the other end of the mounting bracket 112 is connected with the float body 111, the magnetic member is disposed in the float body 111, the float body 111 is made of low-density material, when the float body 111 is immersed in liquid and subjected to buoyancy, the float body rotates around the rotating shaft to drive the magnetic member to swing relative to the mounting frame 112, and after the position of the float body 111 is changed, thereby causing a change in the strength of the surrounding magnetic field, and the hall sensor determines the change in the liquid level in the water tank assembly 200 and/or the current position of the water tank assembly 200 from the received change information. By providing the limiting portion 114 on the mounting bracket 112, the limiting portion 114 limits the rotation of the connecting portion 113, and when the liquid level in the water tank assembly 200 reaches a predetermined height, the connecting portion 113 abuts against the limiting portion 114. Therefore, as shown in fig. 2 and 4, if the magnetic component floats to the detection range of the hall sensor, that is, the hall sensor detects that the magnetic component floats to the detection range P, it indicates that the liquid level in the water tank assembly 200 reaches the preset height, and the water tank assembly 200 is installed in place, it can be understood that the hall sensor can send a corresponding signal to the cleaning system through the controller of the base station and electrically connected with the hall sensor, and then the hall sensor can tell the cleaning device, and/or the base station body, and/or the water tank assembly 200 that there is liquid in the water tank assembly 200, the liquid reaches the specified liquid level, and the water tank assembly 200 is accurately installed on the base station body.

When no liquid or less liquid exists in the water tank assembly 200 and the liquid level does not reach the designated height, the connecting portion 113 and the limiting portion 114 do not abut against each other, the float body 111 sinks or does not reach the designated position, and at this time, the magnetic member does not float to the detection range of the hall sensor, as shown in fig. 3 and 5, that is, the hall sensor does not detect that the magnetic member floats to the detection range, which indicates that the liquid level of the liquid in the water tank assembly 200 does not reach the designated height at this time and/or the water tank assembly 200 is not installed in place, it can be understood that, because the hall sensor is electrically connected with the controller, the hall sensor can send a corresponding signal to the cleaning system at this time, and tell the cleaning device, and/or the base station body, and/or the water tank assembly 200 that the liquid in the water tank assembly 200 is short of liquid and/or the water tank assembly 200 is not installed in place, reminding the user of the need of timely fluid infusion and checking whether the connection between the water tank assembly 200 and the base station body is reliable and accurate.

Wherein, pedestal 115 and connecting portion 113 can be structure as an organic whole, and such setting is favorable to improving the reliability that float body 111 and connecting portion 113 are connected, simultaneously, is favorable to batch production, reduces manufacturing cost and installation cost.

Further, one of the seat body 115 and the cover body 116 is provided with a mounting portion 117, and the other is provided with a limiting structure adapted to the mounting portion 117, the non-contact sensed element 140 is mounted on one of the seat body 115 and the cover body 116 through the mounting portion 117, and the non-contact sensed element 140 mounted on the mounting portion 117 is limited through the limiting structure, so that the non-contact sensed element 140 can be reliably and stably mounted on the float body 111, that is, in the process that the float body 111 floats under the action of liquid, the non-contact sensed element 140 on the float body 111 is immobile relative to the float body 111, and the accuracy of the liquid level detection device in detecting the liquid level and the current position of the water tank assembly 200 is ensured.

Wherein, installation department 117 sets up on pedestal 115, and limit structure sets up on lid 116, perhaps, installation department 117 sets up on lid 116, and limit structure sets up on pedestal 115, and installation department 117 and limit structure's different positions that set up can satisfy the demand of installation department 117 and limit structure isostructure, have enlarged the application range of product.

Specifically, as shown in fig. 7 and 8, the mounting portion 117 includes a mounting groove disposed on the seat body 115, the limiting structure includes a first protruding structure 118 disposed on the cover body 116, an end of the first protruding structure 118 away from the cover body 116 is adapted to be located in the mounting groove, so that after the non-contact sensed component 140 is mounted in the mounting groove, in a process of connecting the cover body 116 and the seat body 115, the first protruding structure 118 is located in the mounting groove and abuts against the non-contact sensed component 140, the non-contact sensed component 140 can be reliably and firmly fixed between the mounting groove and the first protruding structure 118, so that the non-contact sensed component 140 is stationary with respect to the float body 111 in a floating process of the float body 111.

In some possible implementation embodiments provided by the present invention, the float body 111 may be a solid structure or a hollow structure, and different structures of the float body 111 can meet different structural requirements of the float assembly 110, thereby expanding the application range of the product.

Specifically, when the float body 111 is of a solid structure, if the float assembly 110 is not provided with one of the non-contact sensing element 130 and the non-contact sensed element 140, the seat body 115 and the cover body 116 may be of an integral structure and set as a solid structure, or the seat body 115 and the cover body 116 are of a separate structure, and after the cover body 116 covers the seat body 115, there is no gap therebetween to form a solid structure; when the float body 111 is a solid structure and the float assembly 110 is provided with one of the non-contact sensing element 130 and the non-contact sensed element 140, the space of the installation cavity matches the external dimensions of the non-contact sensing element 130 or the non-contact sensed element 140, that is, the non-contact sensing element 130 or the non-contact sensed element 140 is installed in the installation cavity, after the cover 116 covers the seat 115, there is no gap between the cover 116 and the seat 115, and there is no gap between the non-contact sensing element 130 or the non-contact sensed element 140 and between the cover 116 and the seat 115, and the float body 111 is a solid structure.

When the float body 111 is a hollow structure, the space of the installation cavity is larger than the external dimensions of the non-contact sensing element 130 or the non-contact sensed element 140, so that after the non-contact sensing element 130 or the non-contact sensed element 140 is installed in the installation cavity and the cover 116 covers the seat 115, a gap is formed between the non-contact sensing element 130 or the non-contact sensed element 140 and the cover 116 and the seat 115, and the float body 111 is a hollow structure. It is understood that the non-contact sensing element 130 or the non-contact sensed element 140 may not be disposed in the installation cavity, that is, the float body 111 is a hollow structure and the float assembly 110 is not disposed with the non-contact sensing element 130 or the non-contact sensed element 140.

In some possible embodiments provided by the present invention, as shown in fig. 7, at least one of the connection portion 113 and the float body 111 is provided with an anti-installation structure 120, and the anti-installation structure 120 is provided to prevent the float formed by the connection portion 113 and the float body 111 from being reversely assembled with respect to the mounting bracket 112, for example, the anti-installation structure 120 can prevent the float formed by the connection portion 113 and the float body 111 from being reversely assembled with respect to the bottom wall of the water tank assembly 200, so as to prevent the position of the non-contact inductive element 130 or the non-contact inductive element 140 mounted on the float body 111 with respect to the bottom wall of the water tank assembly 200 from being changed to affect the accuracy of detecting the liquid level in the water tank assembly 200 and the position of the water tank assembly 200.

Wherein, anti-structure 120 of adorning can set up on float body 111, also can set up on connecting portion 113, also can set up simultaneously on float body 111 and connecting portion 113, and anti-structure 120 of adorning's different positions of setting can satisfy the demand of connecting portion 113 and the different structures of float body 111. For example, when the seat body 115 of the float body 111 and the connection portion 113 are integrated, the anti-reverse structure 120 is disposed on the connection portion 113, so that the float body 111 can be prevented from being reversely assembled with respect to the water tank assembly 200. It can be understood that the anti-reverse structure 120 may be directly disposed on the float body 111 to prevent the float body 111 from reversely mounting on the water tank assembly 200, or the anti-reverse structure 120 may be disposed on both the float body 111 and the connecting portion 113 to play a role of dual warning to prevent the float body 111 from reversely mounting on the water tank assembly 200.

Further, pedestal 115 and connecting portion 113 structure as an organic whole, prevent adorning anti-structure 120 including setting up in the protruding structure of second in connecting portion 113 bottom, through the setting of the protruding structure of second, can avoid float body 111 to be anti-for the bottom wall of water tank set spare 200, and the protruding structure of second is convenient to be processed, easily realizes, and can not have the problem of ponding to have good warning effect, be suitable for popularization and application. It is understood that the anti-reverse structure 120 may be other structures that meet the requirements, and the present invention is not particularly limited.

In some possible embodiments provided by the invention, as shown in fig. 7, the connection portion 113 is provided with a drainage hole 119, and the drainage hole 119 penetrates through the connection portion 113 in the vertical direction, that is, the drainage hole 119 penetrates through the top and the bottom of the connection portion 113, so that in the process that the float body 111 floats up and down, water flow can continuously flow through the drainage hole 121, impurities in the water are not easy to attach to the float assembly, and thus bacterial growth and odor generation are reduced.

It is understood that the number of the drain holes 119 may be one, two or more, and the drain holes 119 may be circular holes, square holes, or other shapes as required, and the present invention is not particularly limited.

Further, the top of float body 111 of float subassembly 110 is the curved surface, be cylinder structure if float body 111, or globular structure, or satisfy other structures that require, use cylinder structure as an example, cylinder structure's lateral wall is the top of float body 111, use globular structure as an example, any one face of globular structure is the top of float body 111, set up like this, it is less to make the float body meet the resistance of water at the floating in-process, and then be favorable to improving and detect the sensitivity, simultaneously, the curved surface can carry out the water conservancy diversion to liquid, and then can avoid the top of float body 111 to take place the condition of ponding, be favorable to further promoting the quality of this internal liquid of case.

The float body 111 and the connecting portion 113 together form a float, and the float is made of a low-density material, that is, the float body 111 and the connecting portion 113 are both made of a low-density material, so as to ensure that the float body 111 and the connecting portion 113 can float on the liquid surface under the action of the liquid. It is to be understood that the materials of the float body 111 and the connecting portion 113 may be the same or different, and the present invention is not particularly limited.

In some possible embodiments provided by the present invention, as shown in fig. 9, 10 and 11, the water tank assembly 200 includes a lower case 210, an upper case 220 and a handle 230, wherein an opening is provided at a top end of the lower case 210, the lower case 210 includes a first mounting structure 211, and the upper case 220 is pivotally coupled to the first mounting structure 211 and is capable of opening and closing the opening. That is, the water tank assembly 200 of the present invention is a combined water tank, the water tank is formed by combining the upper casing 220 and the lower casing 210, and when the upper casing 220 closes the opening of the lower casing 210, the liquid can be contained in the closed space formed by the upper casing 220 and the lower casing 210, so as to ensure that the liquid is not scattered. When the upper case 220 opens the opening of the lower case 210, the liquid in the lower case 210 can be poured out by turning or tilting the lower case 210.

Wherein, epitheca and inferior valve form the enclosure space who holds liquid, and float subassembly 110 sets up in the enclosure space, is clear water tank or sewage case according to the water tank subassembly, can rationally set up float subassembly 110's position. Specifically, the float assembly 110 is disposed inside the lower casing 210, and is fixed inside the lower casing 210 through the mounting bracket 112, such as the bottom wall or the side wall of the lower casing 210, one end of the connecting part 113 is rotatably connected to the mounting bracket 112, and the other end is connected to the float body 111, so that the float body 111 can float on the liquid surface under the action of the liquid. The non-contact type sensed element 140 is arranged on the floater body 111, and the non-contact type sensed element 130 is arranged on the base station body, so that when the floater body 111 floats under the action of liquid and drives the non-contact type sensed element 140 to float, the liquid level condition in the lower shell 210 is judged according to the signal range or the existence of a signal sensed by the non-contact type sensed element 130, and whether the lower shell 210 is installed in place can be judged. It is understood that the float assembly 110 may be disposed at a side wall of the lower case 210, or at a side wall of the upper case 220 or a top wall of the upper case 220, and the present invention is not particularly limited.

Further, the handle 230 includes a holding portion 232 and transition portions 231 located at two ends of the holding portion 232, the transition portions 231 are rotatably connected with the lower shell 210, and then the holding portion 232 can be driven to rotate relative to the lower shell 210, and a user can lift the water tank assembly 200 through the holding portion 232 to carry the water tank assembly 200, so that the operation is simple and the use is convenient. Because the handle 230 provided by the embodiment of the invention is rotatably connected with the lower shell 210, and the handle 230 is not rotatably connected with the upper shell 220, the arrangement can effectively prevent the problems that the lower shell 210 is separated from the upper shell 220 and the lower shell 210 is inclined to spill liquid due to unreliable and unlocked connection of the upper shell 220 and the lower shell 210 when a user lifts the water tank assembly 200 through the holding part 232, and the handle 230 is connected with the lower shell 210, thereby being beneficial to improving the carrying reliability of the water tank assembly 200 and avoiding the waste of liquid resources.

In this embodiment, a limiting device 213 may be further disposed on an outer side wall of the lower shell 210, and the limiting device 213 limits a rotation range of the transition part 231 toward the first mounting structure 211 relative to the lower shell 210, that is, the limiting device 213 can limit a rotation range of the transition part 231 toward the first mounting structure 211, such that the rotation range of the transition part 231 toward the first mounting structure 211 is large, and the handheld part is located on a peripheral side of the lower shell 210, for example, the handheld part is located on a peripheral side of the lower shell 210 below the first mounting structure 211, so that after the opening of the upper shell 220 is opened, the upper shell 220 blocks the handheld part on the peripheral side of the lower shell 210, which is not beneficial to moving the handheld part to the upper side of the lower shell 210, and further hinders a user from carrying the water tank assembly 200 by the handheld part to perform operations such as pouring, replenishing the liquid, and carrying the water tank assembly 200. That is, in the embodiment of the present invention, the limit device 213 limits the rotation range of the transition part 231 towards the first mounting structure 211, so that the maximum rotation range of the holding part 232 towards the first mounting structure 211 is that the holding part 232 is located above the lower shell 210, and thus, after the upper shell 220 opens the opening, the upper shell 220 rotates to the rear wall of the lower shell 210, and the holding part 232 is located above the lower shell 210, so that the user can conveniently carry the water tank assembly 200 by the holding part 232 to perform operations such as pouring, replenishing, and carrying the water tank assembly 200, and the operation is simple and the use is convenient.

In some possible embodiments of the present invention, as shown in fig. 10, the lower shell 210 is provided with a second mounting structure 212 connected to the transition portion 231, that is, the transition portion 231 of the handle 230 is rotatably connected to the second mounting structure 212 to rotate the handle 230 relative to the lower shell 210, and the limiting structure 215 includes a limiting inclined surface between the second mounting structure 212 and the first mounting structure 211, so that during the rotation of the transition portion 231 toward the first mounting structure 211, the transition portion 231 abuts against the limiting inclined surface to position the holding portion 232 above the lower shell 210, that is, the situation that the holding portion 232 rotates to the side of the lower shell 210 close to the first mounting structure 211 is avoided. It will be appreciated that the handle 230, in the free state, may be subject to the following two conditions, the first: the transition portion 231 abuts against the stopper 213, and in the second case: the grip 232 abuts against a side wall of the lower case 210 on the side away from the first mounting structure 211. Wherein, the first condition convenience of customers directly lifts up water tank set 200 through handle portion 232, and the second condition water tank set 200 occupation space is little, is convenient for accomodate. When the user needs to rotate the upper shell 220 to open the opening of the lower shell 210, if the handle 230 is in the second condition, the user can directly rotate the upper shell 220 to open the opening of the lower shell 210, and if the handle 230 is in the first condition, the user needs to rotate the handle 30 to the second condition and then rotate the upper shell 220 to open the opening of the lower shell 210. In this way, even if the upper shell 220 opens the opening of the lower shell 210, the user can quickly, smoothly and conveniently lift and take the water tank assembly 200 through the holding part 232, the operation is convenient, and the operation experience of the user is greatly improved. The limiting inclined plane is simple in structure and convenient to machine, manufacturing cost of the water tank assembly 200 is reduced, and the limiting inclined plane is suitable for popularization and application.

The direction from the first mounting structure 211 to the second mounting structure 212 is inclined downwards through the limiting inclined plane, so that after the transition part 231 abuts against the limiting inclined plane, the holding part 232 can be reliably and stably positioned above the lower shell 210, the phenomenon that the holding part rotates to the peripheral side of the lower shell 210 is avoided, the problem that the upper shell 220 obstructs a user to carry the water tank assembly 200 through the holding part 232 after opening the lower shell 210 is solved, and the user can conveniently and quickly carry the water tank assembly 200 through the holding part 232 positioned above the lower shell 210. It can be understood that, through the inclination angle that sets up spacing inclined plane rationally, can adjust transition portion 231 and spacing inclined plane butt back, the specific position of holding portion 232 position in inferior valve 210 top for user's hand can be fast, accurate, conveniently hold the holding portion, and carry water tank assembly 200 through holding portion 232.

Further, the number of the transition portions 231 may be two, and the two transition portions 231 are respectively located at two ends of the holding portion 232 and are respectively rotatably connected with the two second mounting structures 212 at two opposite sides of the lower shell 210 through the two transition portions 231, so that the holding portion 232 can rotate relative to the lower shell 210. The number of the limiting devices 213 may be one or two, if the number of the limiting devices 213 is one, one limiting device 213 may be located between any one of the second mounting structures 212 and the first mounting structure 211, and if the number of the limiting devices 213 is two, each limiting device 213 is located between one of the second mounting structures 212 and the first mounting structure 211.

In the above embodiment, as shown in fig. 10, the top end of the lower shell 210 is provided with the boss structure 214 protruding outward, the first mounting structure 211 and the second mounting structure 212 are arranged on the boss structure 214, so as to avoid the first mounting structure 211 and/or the second mounting structure 212 from being directly arranged on the outer side wall of the lower shell 210 and affecting the strength of the side wall of the lower shell 210, the arrangement of the boss structure 214 is favorable for improving the overall strength of the lower shell 210, and improves the reliability of connection between the lower shell 210 and the upper shell 220, and the reliability of connection between the handle 230 and the lower shell 210. Stop device 213 is provided with spacing inclined plane including setting up the protruding structure on boss structure 214, and one side that protruding structure is close to epitheca 220, and protruding structure is convenient to be processed and is made, easily realizes, and protruding structure sets up on boss structure 214, has reduced stop device 213 to the influence of inferior valve 210 lateral wall intensity, is favorable to further improving the reliability of inferior valve 210.

In some possible embodiments, the second mounting structure 212 includes a mounting hole, the transition portion 231 includes a transition portion, a rotation portion and a protrusion portion, which are connected in sequence, one end of the transition portion away from the rotation portion is connected to the holding portion 232, and the rotation portion is inserted into the mounting hole and can rotate in the mounting hole, that is, the rotation portion can rotate relative to the lower shell 210, so that the rotation portion and the transition portion drive the holding portion 232 to rotate relative to the lower shell 210. Because the bellying card is established in the one side that the transition portion was kept away from to the mounting hole for the portion that rotates drives the synchronous pivoted in-process of bellying, the restriction of bellying does not make the portion that rotates break away from the mounting hole, and the setting of bellying and rotation portion makes handle 230 rotate for inferior valve 210, and can not break away from out in the mounting hole of inferior valve 210 promptly, and handle 230 locks on inferior valve 210 promptly, has improved the reliability that handle 230 is connected with inferior valve 210.

Further, a gap is formed between the rotating portion and the mounting hole, so that the rotating portion can rotate and slide in the mounting hole, and thus, the flexibility of rotation of the handle 230 relative to the lower case 210 is improved.

In some possible embodiments provided by the present invention, as shown in fig. 11, the water tank assembly 200 further includes a handle position 240, the handle position 240 is disposed on the outer bottom wall of the lower casing 210 and/or the outer side wall of the lower casing 210, and the handle position 240 is disposed such that a user can carry or otherwise operate the water tank assembly 200 by holding the handle position 240, or by holding the handle position 240 and the holding part 232, for example, after the upper casing 220 opens the opening of the lower casing 210, the user can pour the liquid in the lower casing 210 by holding the handle position 240 and the holding part 232 respectively, which is simple in operation and convenient in use. On the one hand, attacker position 240 sets up in the outer diapire of inferior valve 210, and on the other hand attacker position 240 sets up in the lateral wall of inferior valve 210, and on the other hand, attacker position 240 sets up position and different quantity including setting up two at the outer diapire and the lateral wall of inferior valve 210 respectively, can satisfy attacker position 240 not the demand of the different structure and different user's demand, has enlarged the application range of product.

Further, since the upper casing 220 is pivotally connected to the lower casing 210 through the first mounting structure 211, after the opening of the lower casing 210 is opened by the upper casing 220, a part of the opening far away from the first mounting structure 211 is opened to a larger space, therefore, when the handle position 240 is disposed on the outer bottom wall of the lower casing 210, the handle position 240 is disposed near the first mounting structure 211, and when the handle position 240 is disposed on the outer side wall of the lower casing 210, the handle position 240 is located below the first mounting structure 211, and thus, the handle position 240 is held by a user to incline the lower casing 210, so that the liquid in the lower casing 210 can rapidly flow out through the part of the opening far away from the first mounting structure 211, that is, the liquid flows out through the part of the opening with the larger space, which is beneficial to improving the pouring efficiency of the liquid, and improving the satisfaction degree of the user.

Further, the handle position 240 can be integrated with the lower casing 210 or be a split structure, and the different setting modes of the handle position 240 and the lower casing 210 can meet the requirements of different structures of the handle position 240. For example, in one aspect, the locking portion 240 includes a groove structure formed on the lower case 210, and for example, the locking portion 240 includes a groove structure formed on the outer bottom wall of the lower case 210 and/or a groove structure formed on the outer sidewall of the lower case 210, and the groove structure is easy to process and low in cost. On the other hand, the handle 240 includes a handle insert connected to the lower case 210, for example, the handle insert is connected to the outer bottom wall of the lower case 210 and/or the outer side wall of the lower case 210 by means of an insert connection, an insertion connection, a clamping connection, or the like, and specifically, the handle insert may be a plate-shaped structure, a rod-shaped structure, or other structures meeting the requirement.

In some possible embodiments provided by the present invention, as shown in fig. 10, the water tank assembly 200 further includes a first sealing member 250, the first sealing member 250 is disposed on at least one of the upper casing 220 and the lower casing 210, and when the upper casing 220 closes the opening of the lower casing 210, a gap between the lower casing 210 and the upper casing 220 is sealed by the first sealing member 250, so as to ensure that a closed space formed by the upper casing 220 and the lower casing 210 has good sealing performance, so that liquid in the closed space does not overflow or leak from the gap between the upper casing 220 and the lower casing 210, and the sealing performance of the water tank assembly 200 is ensured.

Further, the first sealing member 250 may be an elastic member, and the elastic first sealing member 250 is beneficial to improve the sealing performance of the connection between the upper casing 220 and the lower casing 210, specifically, the first sealing member 250 is a sealing ring, a sealing gasket, or other structures meeting the requirement, and the invention is not limited in particular.

It is understood that the first sealing member 250 may be separately provided on the upper casing 220 or the lower casing 210, or may be provided on both the upper casing 220 and the lower casing 210, and in some embodiments of the present invention, as shown in fig. 9 and 10, the first sealing member 250 is provided on the upper casing 220, and in particular, the first sealing member 250 is embedded and connected on the upper casing 220.

In the above embodiment, as shown in fig. 9, 10 and 11, one of the upper casing 220 and the lower casing 210 is provided with the buckling part 222, and the other is provided with the limiting structure 215, wherein the buckling part 222 is rotatably connected with the upper casing 220 or the lower casing 210, and is rotated to be clamped with the limiting structure 215 through the buckling part 222, so that the upper casing 220 and the lower casing 210 can be locked, the upper casing 220 and the lower casing 210 are further tightly and reliably connected, and the buckling part 222 is rotated to be separated from the limiting structure 215, so that the upper casing 220 and the lower casing 210 can be unlocked, and the upper casing 220 can open the opening of the lower casing 210, and the operation is simple.
