[0041] Please refer to Figures 1 to 7The application provides a washing device, which comprises an outer cylinder 100, an inner cylinder 200, a driving device 300, a power supply device 400 and a water quality detection device 500. The inner cylinder 200 is accommodated in the outer cylinder 100, and an avoiding space is defined between the outer side wall of the inner cylinder 200 and the inner side wall of the outer cylinder 100. The inner cylinder 200 is rotatably arranged relative to the outer cylinder 100 to have a rotating state and a rotation-stopping state. The driving device 300 is drivingly connected with the inner cylinder 200. The power supply device 400 comprises a power supply module 410 and an electric connector 420 which are electrically connected. The power supply device 400 is arranged on the outer cylinder 100, and the electric connector 420 is exposedly arranged in the avoiding space. The water quality detection device 500 comprises a water quality detection module 510, an electricity storage module and an electric connector 520 which are electrically connected. The water quality detection module 510 is exposedly arranged on the inner side of the inner cylinder 200, and the electric connector 520 is exposedly arranged in the avoiding space. The electric connector 420 and the electric connector 520 have a relative movement stroke, so that the electric connector 420 and the electric connector 520 are separated when the inner cylinder 200 is in the rotating state, and the electric connector 420 and the electric connector 520 are connected when the inner cylinder 200 is in the rotation-stopping state.

[0042] In the technical scheme, the water quality detection module 510 in the water quality detection device 500 is arranged on the cylinder side wall of the inner cylinder 200, which can reduce the mutual interference between the water quality detection process of the water quality detection module 510 and the working process of the inner cylinder 200, and can form stable support for the water quality detection module 510 by means of the cylinder side wall of the inner cylinder 200, so that the installation imbalance of the water quality detection module 510 caused by the rotating movement of the inner cylinder 200 is avoided.

[0043] The power supply module 410 in the power supply device 400 is arranged on the side wall of the outer cylinder 100, which is spaced apart from the inner cylinder 200 and is closer to the outer side of the whole machine body, so that the user can conveniently perform dismounting operation or control operation on the power supply module 410.

[0044] The electric connecting piece 420 and the electric counter connecting piece 520 are arranged to be connected in a clutching manner, and the separation state and the connection state of the two are associated with the working state of the washing device. When the inner cylinder body 200 is in a rotating state, the washing device is normally running, the water quality detection module 510 generally needs to perform a detection operation in real time or within a set period, at this time, the electric connecting piece 420 is separated from the electric counter connecting piece 520, and does not interfere with the rotating movement of the inner cylinder body 200 compared with the outer cylinder body 100, and avoids operating the electric connection of the two in a water environment; on the contrary, when the inner cylinder body 200 is in a rotation-stopping state, the washing device is idle and stopped, the water quality detection module 510 generally does not need to perform a detection operation, at this time, the electric connecting piece 420 and the electric counter connecting piece 520 are connected, the idle time of the washing device is fully utilized, and the purpose that the power supply module 410 effectively charges the electric counter connecting piece 520 is achieved.

[0045] The water quality detection module 510 does not need to be limited to being installed at the drain pipeline of the washing device, and the installation flexibility of the water quality detection module 510 is facilitated; the water quality detection module 510 can not only extend into the inside of the inner cylinder body 200, but also can achieve more safe, time-saving and efficient charging operation, and the operation reliability of the whole machine is improved.

[0046] Please refer to Figures 1 to 3 In the design, the outer cylinder body 100 can be a shell structure directly exposed outside the whole machine, or in an embodiment, the washing device further comprises a machine shell, and the outer cylinder body 100 is fixedly arranged in the inner cavity of the machine shell. The inner cylinder body 200 rotates around the rotation axis, wherein when the driving device 300 drives the inner cylinder body 200 to continuously rotate, the inner cylinder body 200 is in a rotating state; on the contrary, when the driving device 300 stops driving the inner cylinder body 200 to rotate, the inner cylinder body 200 stops rotating and is in a rotation-stopping state.

[0047] The rotation axis of the inner cylinder body 200 can be the central axis or the eccentric axis of the inner cylinder body 200. The rotation axis can be arranged to extend along the vertical direction or extend along the horizontal direction according to actual needs. In order to facilitate understanding, in the following embodiments, the rotation axis of the inner cylinder body 200 is taken as an example and is arranged to extend along the vertical direction. Figures 1 to 7

[0048] The driving device 300 provides the required driving for the rotating movement of the inner cylinder body 200. The specific form of the driving device 300 is not limited, and can be adjusted according to actual needs. The driving device 300 can be, but is not limited to, a driver such as a motor itself, or a combination of a motor and a required transmission assembly. The transmission assembly can be, but is not limited to, for example, a gear assembly.

[0049] ​In order to ensure the rotation of the inner cylinder 200 relative to the outer cylinder 100 is smooth and without interference, a sufficient gap is reserved between the outer peripheral wall of the inner cylinder 200 and the inner peripheral wall of the outer cylinder 100, defining an annular avoidance space. When the inner cylinder 200 needs to be filled with external water, the water can be filled into the avoidance space, and then introduced into the inner cavity of the inner cylinder 200 through the through hole formed in the cylinder wall of the inner cylinder 200, so as to wet and clean the clothes in the inner cavity of the inner cylinder 200.

[0050] The power supply module 410 in the power supply device 400 can be a power supply circuit specially arranged for the power storage module, a switching circuit electrically connected to the power supply system fixedly arranged in the washing device, or an external circuit directly connected to the mains, without limitation. The power supply module 410 can be sealingly arranged in the avoidance space; or the power supply module 410 can be directly arranged outside the outer cylinder 100, so as to avoid the water in the avoidance space and the inner cylinder 200 as much as possible, and to facilitate maintenance, disassembly, replacement, etc. of the power supply module 410.

[0051] The water quality detection module 510 in the water quality detection device 500 is the main structure for performing the water quality detection function, for example, a mature water quality detection sensor module or product. The detection parameters and detection principles of the water quality detection module 510 can be specifically set according to actual needs.

[0052] The power storage module in the water quality detection device 500 can be but is not limited to a battery structure. Specifically, the power storage module is arranged as a rechargeable battery, which can store sufficient power for the water quality detection module 510 to perform the water quality detection function for a predetermined number of times or time length. When the power is insufficient, the power supply module 410 can supply power through the electrical connection of the electrical connecting member 420 and the electrical counter connecting member 520.

[0053] The electrical connecting member 420 and the electrical counter connecting member 520 can be mating wire terminals, for example, an electrical plug and an electrical socket, or two electrically matched electrical contacts. Further, according to actual needs, the electrical connecting member 420 and the electrical counter connecting member 520 are respectively provided with a waterproof structure, so as to ensure that the electrical connection between them is not affected by the water.

[0054] There are various schemes for the waterproof structure:

[0055] In an embodiment, the waterproof structure can be a hydrophobic structure arranged on the outer surface of the electrical connecting member 420 and the electrical counter connecting member 520. When the inner cylinder is in the rotation-stopping state and the water in the avoidance space is discharged outward, the outer surface of the electrical connecting member 420 and the electrical counter connecting member 520 does not remain too much liquid, so that when the electrical connecting member 420 and the electrical counter connecting member 520 are electrically connected, there will be no electrical failure caused by liquid.

[0056] In an embodiment, the waterproof structure can be a waterproof film layer arranged on the outer surface of the electric connector 420 and the electric counterpart 520. The waterproof film layer can effectively isolate liquid, but does not affect the electrical connection between the electric connector 420 and the electric counterpart 520.

[0057] In addition, the electric connector 420 and the electric counterpart 520 can also be electrically connected through wireless power transmission technology, for example, through electromagnetic induction. In this way, the water and electricity isolation of the electric connector 420 and the electric counterpart 520 can be effectively achieved.

[0058] It should be noted that the communication connection between the water quality detection module 510 and the external environment can also be achieved through wireless connection, for example, but not limited to, Bluetooth, local area network, WiFi, etc. In this way, the water quality detection module 510 can basically complete the communication operation and charging operation without the need for wired connection such as cable.

[0059] Of course, in an embodiment, the power supply device 400 and at least the electric counterpart 520 in the water quality detection device 500 are arranged at the upper region of the avoidance space. The specific range of the upper region can be limited according to actual needs. However, it can be understood that the water level in the avoidance space can be high or low according to actual application requirements. The upper region of the avoidance space refers to the region where the water level basically does not reach. In this way, when the power supply device 400 and the electric counterpart 520 are arranged at the upper region of the avoidance space, the contact with the liquid in the avoidance space can be reduced, thereby ensuring the water and electricity isolation of the electric connector 420 and the electric counterpart 520, and being more secure.

[0060] The water quality detection module 510 arranged on the inner side wall of the inner cylinder 200 can be one or at least two according to actual needs. When the water quality detection module 510 is at least two, each water quality detection module 510 can be arranged according to actual needs, for example, arranged along the water depth direction after the washing device is filled with water, and / or arranged along the same horizontal direction, etc.

[0061] Each water quality detection module 510 can be correspondingly provided with an electricity storage module. Or each water quality detection module 510 can be supplied with power through the same electricity storage module. The number of electric counterparts 520 is corresponding to the number of electricity storage modules, so that each electricity storage module can be supplied with power by the power supply module 410.

[0062] Specifically in an embodiment, when the water quality detection modules 510, the power storage modules and the electrical connectors 520 are respectively one-to-one corresponding, each water quality detection module 510 can be arranged at intervals along the rotation circumferential direction of the inner cylinder 200. In this way, by controlling the position of the inner cylinder 200 in the rotation-stopping state by the driving device 300, the corresponding power storage module and electrical connector 520 of each water quality detection module 510 can pass through and be electrically connected with the electrical connector 420 in turn.

[0063] In order to realize the connectable and disconnectable connection between the electrical connector 420 and the electrical connector 520, at least one of the electrical connector 420 and the electrical connector 520 is movably arranged relative to the other, so as to have a relative movement stroke of approaching each other for connection and moving away from each other for disconnection. The specific form of the relative movement stroke is not limited, which can be one or several of translational movement or rotational movement along the radial direction of the inner cylinder 200 (i.e. the arrangement direction between the electrical connector 420 and the electrical connector 520), the axial direction, the circumferential direction or the tangential direction.

[0064] In the present design, the relative movement stroke of both the electrical connector 420 and the electrical connector 520 is associated with the rotation state and the rotation-stopping state of the inner cylinder 200:

[0065] In an embodiment, a control device is pre-set inside the washing device, and the washing device is specially configured with a power device for the relative movement stroke of the electrical connector 420 and the electrical connector 520. At this time, the control device is electrically connected with the driving device 300 and the power device respectively. When the control device controls the driving device 300 to start running, i.e. drives the inner cylinder 200 to move to the rotation state, the power device is synchronously or asynchronously controlled to start running, thereby driving the electrical connector 420 and the electrical connector 520 to move away from each other; conversely, when the control device controls the driving device 300 to stop running, i.e. drives the inner cylinder 200 to move to the rotation-stopping state, the power device is synchronously or asynchronously controlled to start running or stop running, thereby driving the electrical connector 420 and the electrical connector 520 to move to connect with each other.

[0066] Alternatively, in an embodiment, without additionally setting the power device, the relative movement stroke of both the electrical connector 420 and the electrical connector 520 is directly driven and realized by the rotation movement state of the inner cylinder 200. Specifically, the water quality detection device 500 further comprises a butt protrusion 530, which is protruded on the outer side wall of the inner cylinder 200, and at least part of the butt protrusion 530 is made of elastic material, so as to be able to be driven to be bent and deformed when the inner cylinder 200 is in the rotation state; the electrical connector 520 is arranged close to the free end of the butt protrusion 530.

[0067] It can be understood that the above description is combined with the accompanying drawings Figures 3 to 5The docking protrusion 530 is protruded on the outer sidewall of the inner cylinder 200, that is, when the inner cylinder 200 is in a rotating state, the docking protrusion 530 can revolve around the rotation axis of the inner cylinder 200 along with the inner cylinder 200. The docking protrusion 530 is subjected to a rotating centrifugal force, and since the size of the rotating centrifugal force is substantially related to the rotating radius and the mass of the docking protrusion 530, when at least a part of the docking protrusion 530 is made of an elastic material, and particularly, the elastic arrangement of the docking protrusion 530 needs to deviate from the free end of the docking protrusion 530. In this way, the docking protrusion 530 can be subjected to centrifugal forces of different sizes on both sides of the elastic arrangement, forming a centrifugal force difference. The centrifugal force difference causes the docking protrusion 530 to be bent and deformed locally, and the bending and deformation is along the rotation direction, so that the distance between the electrical docking part 520 arranged at or adjacent to the free end of the docking protrusion 530 and the electrical connecting part 420 is increased, and the two are separated from each other, ensuring that the rotation of the inner cylinder 200 is not interfered. When the inner cylinder 200 stops rotating, the centrifugal force difference gradually decreases until it is eliminated, the docking protrusion 530 is elastically reset, the distance between the electrical docking part 520 and the electrical connecting part 420 gradually approaches, and the two are connected.

[0068] Particularly, in an embodiment, the entire docking protrusion 530 is made of an elastic material, which is more conducive to the processing and molding of the docking protrusion 530, and simplifies the molding process of the docking protrusion 530. The docking protrusion 530 is wrapped on the outer sidewall of the electrical docking part 520, which helps to enhance the connection strength of the docking protrusion 530 and the electrical docking part 520, and at the same time, the docking protrusion 530 made of an elastic material can provide good peripheral protection for the electrical docking part 520.

[0069] It should be noted that when the docking protrusion 530 is wrapped on the outer sidewall of the electrical docking part 520, at least the part of the electrical docking part 520 connected to the electrical connecting part 420 needs to be exposed outside the docking protrusion 530 to avoid poor electrical contact between the electrical connecting part 420 and the electrical docking part 520.

[0070] In addition, the docking protrusion 530 can also extend to cover the outside of the water quality detection module 510 and / or the power storage module. It can be understood that, since the water quality detection module 510 and the electrical docking member 520 are arranged on the inside and outside of the inner cylinder 200 respectively, in order to realize the electrical connection of the water quality detection module 510, the power storage module and the electrical docking member 520, the inner cylinder 200 can be provided with a connecting hole along the thickness direction of the inner cylinder 200, and the water quality detection module 510 is exposed on the inside of the inner cylinder 200 through the connecting hole. The power storage module can be arranged on the inside of the inner cylinder 200, in the connecting hole, or on the outside of the inner cylinder 200 (i.e. in the avoiding space) according to actual needs. By extending the docking protrusion 530 to cover the outside of the water quality detection module 510 and / or the power storage module, the peripheral protection as described above can be realized, and at the same time, a certain sealing effect can be achieved to ensure the sealed connection between the water quality monitoring device and the connecting hole.

[0071] In view of the above, when the inner cylinder 200 is in a rotating state, the degree of bending deformation of the docking protrusion 530 can be specifically set according to actual needs. It can be understood that, when the degree of bending deformation of the docking protrusion 530 is small, it is helpful to prevent the free end of the docking protrusion 530 from colliding with the outer sidewall of the inner cylinder 200, but the separation distance between the electrical docking member 520 and the electrical connecting member 420 is small, which easily leads to the failure of complete separation of the two; on the contrary, when the degree of bending deformation of the docking protrusion 530 is large, it is helpful to sufficiently separate the separation distance between the electrical docking member 520 and the electrical connecting member 420, but to a certain extent, it easily leads to the collision of the free end of the docking protrusion 530 with the outer sidewall of the inner cylinder 200. Therefore, further, in an embodiment, the outer sidewall of the inner cylinder 200 is provided with at least two elastic pad layers along the circumferential direction of the inner cylinder 200, the elastic pad layers are arranged on both sides of the docking protrusion 530, and when the docking protrusion 530 is bent and deformed to approach, the elastic pad layers elastically abut against the docking protrusion 530. In this way, the degree of bending deformation of the docking protrusion 530 can be adjusted according to actual needs, and even if the free end of the docking protrusion 530 collides with the outer sidewall of the inner cylinder 200, the setting of the elastic pad layer can convert the collision into a flexible contact, thereby achieving a certain buffering effect.

[0072] Based on any of the above embodiments, in a further scheme, the outer cylinder 100 is provided with a mounting hole 110 along the thickness direction of the outer cylinder 100, and the power supply module 410 is detachably mounted on the outer sidewall of the outer cylinder 100. The power supply device 400 further comprises a connecting protrusion 430 and a sealing member 440. The connecting protrusion 430 is arranged in the mounting hole 110 from the outside to the inside, and protrudes inwardly from the inner sidewall of the outer cylinder 100. The sealing member 440 is arranged between the circumferential sidewall of the connecting protrusion 430 and the hole wall of the mounting hole 110.

[0073] It can be understood that the connecting protrusion 430 and the above-mentioned docking protrusion 530 can be alternatively arranged, thereby facilitating the overall structural simplification; or both can be arranged at the same time, that is, both the connecting protrusion 430 and the docking protrusion 530 are arranged, thereby facilitating the shortening of the single protruding length of the connecting protrusion 430 and the docking protrusion 530. The sealing member 440 can effectively seal the installation gap between the connecting protrusion 430 and the mounting hole 110, thereby avoiding the water inside the outer cylinder 100 from leaking outwards.

[0074] Further, please refer to Figure 3 , Figure 6 and Figure 7 , in an embodiment, the connecting protrusion 430 is arranged to be telescopically adjustable along the hole depth direction of the mounting hole 110; the power supply device 400 further comprises an adjusting member 450, which is connected between the connecting protrusion 430 and the power supply module 410. When the power supply module 410 is powered, the adjusting member 450 adjusts the connecting protrusion 430 to extend towards the inner cylinder 200; when the power supply module 410 loses power, the adjusting member 450 adjusts the connecting protrusion 430 to retract away from the inner cylinder 200. The protruding length of the connecting protrusion 430 is arranged to be telescopically adjustable, thereby the distance between the connecting protrusion 430 and the docking protrusion 530 can be adjusted through the telescopic movement of the connecting protrusion 430. When the docking protrusion 530 is bent and deformed and / or the connecting protrusion 430 retracts away from the inner cylinder 200, the distance between the electric connecting member 420 and the electric docking member 520 increases, thereby ensuring the effective separation of the two; conversely, when the docking protrusion 530 resets and / or the connecting protrusion 430 extends towards the inner cylinder 200, the distance between the electric connecting member 420 and the electric docking member 520 decreases, thereby ensuring the close connection of the two. The arrangement of the adjusting member 450 can realize the telescopic movement of the connecting protrusion 430 and the power-on state and power-off state of the power supply module 410. In this way, when the power supply module 410 is powered, the adjusting member 450 adjusts the connecting protrusion 430 to extend towards the inner cylinder 200, thereby realizing the electrical connection of the electric connecting member 420 and the electric docking member 520, and the power storage module obtains power supply. Conversely, when the power supply module 410 loses power, the adjusting member 450 adjusts the connecting protrusion to retract away from the inner cylinder 200, thereby the electric connecting member 420 and the electric docking member 520 are separated, thereby ensuring that the power supply device 400 will not be electrified.

[0075] Specifically, in an embodiment, the adjusting member 450 is electrically connected with the power supply module 410, and the adjusting member 450 is at least partially made of an electrostrictive material. The electrostrictive material refers to an electrostrictive material that will produce elongation deformation in the power-on state and will reset to the shortened state or will produce shortening deformation in the power-off state. Specifically, for example, a piezoelectric material.

[0076] Further, in an embodiment, the sealing member 440 includes a first ring portion 441 fixedly sleeved on the outer circumferential side of the connecting protrusion 430, a second ring portion 442 fixedly sleeved on the outer circumferential side of the mounting hole 110, and a connecting portion 443 connected between the first ring portion 441 and the second ring portion 442, the connecting portion 443 being elastically deformable along the hole depth direction of the mounting hole 110. The first ring portion 441 realizes firm connection between the sealing member 440 and the connecting protrusion 430, the second ring portion 442 realizes firm connection between the sealing member 440 and the outer cylinder body 100, and the connecting portion 443 is elastically deformable, so that the sealing member 440 can be both firmly connected with the connecting protrusion 430 and the outer cylinder body 100 and dynamically adapt to the expansion and contraction of the connecting protrusion 430.

[0077] Please refer to Figure 7 In an embodiment, the electrical connector 420 and the electrical counterpart 520 are provided with a magnetic attraction structure 610 and a magnetic cooperation structure 620 at one of the positions close to the connection between the two, and the other is provided with a magnetic cooperation structure 620. When the electrical connector 420 and the electrical counterpart 520 are close, the magnetic attraction structure 610 and the magnetic cooperation structure 620 are magnetically attracted and fixed. The magnetic attraction structure 610 is, for example, a magnet, and the magnetic cooperation structure 620 contains at least one of iron, cobalt and nickel. The arrangement of the magnetic attraction structure 610 and the magnetic cooperation structure 620 helps to firmly attract and connect the electrical connector 420 and the electrical counterpart 520 when they are close to a set distance, avoiding disconnection of the electrical connector 420 and the electrical counterpart 520 when they need to be connected. The magnetic attraction structure 610 and the magnetic cooperation structure 620 can be arranged on the circumferential side of the electrical connector 420 and the electrical counterpart 520 as much as possible without adversely interfering with the connection process of the electrical connector 420 and the electrical counterpart 520.

[0078] In addition, in an embodiment, the washing device further includes a control device, which is electrically connected to the driving device 300 and the power supply device 400 respectively, to control the power supply device 400 to work according to the working state of the washing device and the running state of the driving device 300. The control device can realize intelligent association of the working state of the washing device, the running state of the driving device 300 and the power supply state of the power supply device 400, to ensure that when the washing device is in a preset working mode and the driving device 300 starts to run, the power supply device 400 loses power, thereby avoiding power loss or safety hazards such as electric leakage of the power supply device 400. Conversely, when the washing device is in a preset non-working mode and the driving device 300 stops running, the power supply device 400 is powered, fully utilizing the idle time of the washing device to effectively supply power to the power storage module corresponding to the water quality detection module 510.

[0079] Based on any of the above embodiments, there are various schemes to ensure that the electrical connector 420 and the electrical counterpart 520 are accurately mated:

[0080] In an embodiment, the rotation angle of the inner cylinder 200 relative to the outer cylinder 100 can be accurately controlled by the driving device, so that the position of the inner cylinder 200 relative to the outer cylinder 100 remains fixed when the inner cylinder 200 is in the rotation-stopping state each time, i.e., at the position where the electrical connector 420 and the electrical counterpart 520 are just opposite to each other.

[0081] Alternatively, in an embodiment, the electrical connector 420 is arranged in multiple along the circumferential direction of the inner cylinder 100. At least two of the electrical connectors 420 can be electrically connected to the same power supply module 410, or each electrical connector 420 is electrically connected to an independent power supply module 410. In this way, the number of electrical connectors 420 that can be electrically connected to the electrical counterpart 520 is more, so that the area range in which the electrical connector 420 and the electrical counterpart 520 are electrically connected is larger, which helps to improve the probability of accurate connection between the electrical connector 420 and the electrical counterpart 520.

[0082] In an embodiment, the electrical connector 420 can be arranged in a ring shape along the circumferential direction of the inner cylinder 100. In this way, the electrical connector 420 can be arranged on the entire rotation path of the electrical counterpart 520, so that when the inner cylinder 100 stops rotating at any position, the electrical counterpart 520 can be ensured to be mated with the electrical connector 420.

[0083] The above description is only the preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation based on the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
