This allows the second conductive element and the winding turntable to abut against two opposing cavity walls of the mounting cavity, ensuring that the winding turntable, the first conductive element, and the second conductive element remain stably positioned within the mounting cavity when energized, thus preventing shaking. Furthermore, since the second conductive element is stationary relative to the winding shell, even if the second conductive element is electrically connected to the control element, wire entanglement will not occur.

[0054] refer to Figures 1-9 A water dispensing assembly includes a water dispensing component 1, a solenoid valve 2, a liquid level detection component 3, a height detection component 4, and a control component 5. This water dispensing assembly can be used in a water dispenser.

[0055] refer to Figure 1 In this embodiment, the water outlet 1 is generally L-shaped like a faucet. The water outlet 1 includes an outer pipe 11 and an inner pipe 12. (Refer to...) Figure 9 The inner tube 12 is located inside the outer tube 11 and has a water outlet 121 to discharge water into a container on the bearing surface 6. The water outlet end of the water outlet 121 is arranged downwards. The bearing surface 6 can be formed by a platform for the installation of the water outlet component 1. In some embodiments, the water outlet component 1 has a bearing surface 6.

[0056] refer to Figure 2 The solenoid valve 2 is suitable for opening and closing the water outlet 121 to allow water to flow out or stop the water outlet 121.

[0057] The liquid level detection element 3 is suitable for directly or indirectly acquiring the liquid level in a container. Direct acquisition means the detected data is the liquid level in the container; indirect acquisition requires calculation or conversion to obtain the liquid level. (Reference) Figure 3 , Figure 7 The liquid level detection component 3 includes a mounting component 31 and a liquid level sensor 32. The mounting component 31 is installed on the water outlet component 1. Preferably, the mounting component 31 and the water outlet component 1 are detachably connected for future maintenance. The detachable connection can be achieved by snap-fit, screw connection, etc. The mounting component 31 has a first groove 311 with the opening of the first groove 311 facing upwards. The liquid level sensor 32 is installed in the first groove 311 of the mounting component 31 and is located at the bottom of the groove. The surface of the mounting component 31 facing away from the liquid level sensor 32 is a spherical surface 312. The liquid level sensor 32 senses downwards and is suitable for measuring the distance between itself and the liquid in the container after passing through the spherical surface 312. Specifically, the liquid level in the container can be obtained as follows: the liquid level L0 in the container (including the bottom wall thickness of the container) = the distance L1 from the liquid level sensor 32 to the bearing surface 6 - the distance L2 from the liquid level sensor 32 to the liquid in the container. The liquid level sensor 32 can be a capacitive liquid level sensor, an ultrasonic liquid level sensor, a radar liquid level sensor, a photoelectric liquid level sensor, etc.

[0058] The height detecting member 4 is adapted to directly or indirectly acquire the height of the container, the direct and indirect meanings of which are similar to the principle of the liquid level detecting member 3 adapted to directly or indirectly acquire the liquid level in the container. The height detecting member 4 comprises a driving member 41, a height measuring member 42, a first signal shielding member 431, a second signal shielding member 432, a screw rod 44, a winding turntable 45, a winding shell 46, a first conductive member 471, a second conductive member 472 and a coil 48.

[0059] Reference Figure 8 The height measuring member 42 is adapted to sense whether the container exists in the horizontal direction, and comprises a shielding shell 421 and a height measuring sensor 422. The shielding shell 421 is provided with an opening 4211 and a cavity 4212 in communication with the opening 4211. The size of the opening 4211 gradually expands along the direction close to the surface of the shielding shell 421. The angle between the hole wall of the opening 4211 and the horizontal direction can be 5-15 degrees. The height measuring sensor 422 is arranged in the cavity 4212 of the shielding shell 421. The signal of the height measuring sensor 422 is adapted to pass through the opening 4211 to sense whether the container exists in the horizontal direction. The height measuring sensor 422 can be a laser sensor, an infrared sensor, a photoelectric sensor, a radar sensor, etc. Whether the measured distance changes suddenly is used to determine whether the container exists, for example, when the height measuring sensor 422 moves from bottom to top to measure, the height measuring sensor 422 can measure the container in the sensing range at first, which shows 5 cm. When the height measuring sensor 422 cannot sense the container, it shows infinite (some show the maximum measurement value or error), which is regarded as a sudden change. Similarly, when the height measuring sensor 422 moves from top to bottom to measure, the height measuring sensor 422 first cannot sense the container, and changes from infinite to a valid value, which is regarded as a sudden change.

[0060] The first signal shielding member 431 and the second signal shielding member 432 are installed on the water outlet member 1. The first signal shielding member 431 is located below the second signal shielding member 432. In other embodiments, the first signal shielding member 431 can be located above the second signal shielding member 432. The height measuring member 42 is adapted to send a back-and-forth signal when sensing the first signal shielding member 431, to indicate that the maximum height measuring distance is reached. The height measuring member 42 is adapted to send a stop signal when sensing the second signal shielding member 432, to indicate that the initial position is reset.

[0061] The driving member 41 is a rotating motor in this embodiment, and can also be a telescopic motor, etc. in other embodiments. The driving member 41 is adapted to drive the height measuring member 42 to move in the vertical direction. Specifically, reference Figure 8 The driving member 41 is adapted to drive the screw rod 44 to rotate. The screw rod 44 is rotationally connected with the outer pipe 11. The shielding shell 421 of the height measuring member 42 is threadedly connected with the screw rod 44, and rotationally connected with the outer pipe 11 of the water outlet member 1. Thus, when the screw rod 44 rotates, the height measuring member 42 is lifted.

[0062] ReferenceFigure 6 The winding shell 46 is fixed to the outer tube 11 of the water outlet 1, and is provided with a mounting cavity 461 having two wire passing openings. One wire passing opening is used for the coil 48 to pass out to be electrically connected with the height measuring sensor 422 of the height measuring member 42, and the other wire passing opening is used for the electric wire of the second conductive member 472 to pass out to be electrically connected with the control member 5. The winding disc 45, the first conductive member 471 and the second conductive member 472 are all arranged in the mounting cavity 461.

[0063] With reference to Figure 4 The height measuring member 42 is electrically connected with the control member 5 through the coil 48. Specifically, the height measuring sensor 422, the coil 48, the first conductive member 471, the second conductive member 472 and the control member 5 are electrically connected in sequence to realize conduction. The coil 48 is wound on the winding disc 45.

[0064] With reference to Figure 8 The winding disc 45 is arranged in the mounting cavity 461, and one end of the winding disc 45 abuts against the cavity wall of the mounting cavity 461, and has a bevel gear extending out of the mounting cavity 461 to realize meshing transmission with the bevel gear on the lead screw 44 to realize the winding and unwinding actions when the lead screw 44 rotates. The other end of the winding disc 45 is rotationally connected with the first conductive member 471 to rotate synchronously. In the embodiment, the rotationally connection is realized by the two insertion columns 451 of the winding disc 45 and the two insertion slots 4711 of the first conductive member 471. In other embodiments, other ways can be adopted.

[0065] At least one of the first conductive member 471 and the second conductive member 472 is provided with an elastic contact 4712 which is adapted to abut against the other to realize electrical connection, and makes the second conductive member 472 and the winding disc 45 abut against the two opposite cavity walls of the mounting cavity 461 respectively, so that the positions of the winding disc 45, the first conductive member 471 and the second conductive member 472 in the mounting cavity 461 are stable. In the embodiment, the first conductive member 471 is provided with the elastic contact 4712.

[0066] The control member 5 is electrically connected with the liquid level detecting member 3 and the height detecting member 4, so as to obtain the data measured by the two members, to obtain (including directly obtain and obtain by calculation) the liquid level in the container and the height of the container. The control member 5 is adapted to obtain the liquid level in the container and the height of the container, and is adapted to control the electromagnetic valve 2 to close the water outlet 121 to prevent water from overflowing the container when the liquid level in the container / the height of the container is greater than or equal to a first threshold value. The first threshold value should be less than or equal to 100%, the first threshold value can be set to multiple, and is controlled by multiple trigger switches (each trigger switch is electrically connected with the control member 5) respectively, the first threshold value can be 30%, 50%, 70%, 100% and the like, so as to meet different water adding requirements. In the embodiment, the control member 5 controls the electromagnetic valve 2 to close the water outlet 121 to prevent water from overflowing the container at least when the liquid level in the container is greater than or equal to the height of the container. For example, when the first threshold value is 100%, a second threshold value can be additionally set, so that the electromagnetic valve 2 is controlled to close the water outlet 121 to prevent water from overflowing the container when the liquid level in the container / the height of the container is equal to the first threshold value-second threshold value, so as to prevent water from overflowing the container when the container is carried. In the embodiment, the control member 5 obtains the height of the container according to the movement stroke of the height detecting member 42 when the information sensed by the height detecting member 42 is suddenly changed. The movement stroke of the height detecting member 42 can be determined by multiplying the number of rotations of the driving member 41 and the movement distance of the height detecting member 42 per rotation. When the height detecting member 42 moves from bottom to top to measure the height of the container, the distance between the height detecting member 42 and the bearing surface 6 at the initial time+the movement stroke of the height detecting member 42 is equal to the height of the container. When the height detecting member 42 moves from top to bottom to measure the height of the container, the distance between the height detecting member 42 and the bearing surface 6 at the initial time-the movement stroke of the height detecting member 42 is equal to the height of the container.

[0067] In other embodiments, other ways can be used to obtain the movement stroke of the height detecting member 42.

[0068] The control member 5 is adapted to control the driving member 41 to move the height detecting member 42 to the initial position in the opposite direction when receiving a back-and-forth signal, so as to prevent damage. The control member 5 is adapted to control the driving member 41 to stop the height detecting member 42 at the initial position when receiving a stop signal, so as to accurately stop.

[0069] In use, reference is made to Figures 7-9The container is placed on the bearing surface 6, the key starts the electromagnetic valve 2, the electromagnetic valve 2 opens the water outlet 121, and the water outlet 121 discharges water into the container. At the same time, the control member 5 controls the driving member 41 to act, the output end of the driving member 41 rotates to drive the lead screw 44 to rotate, thereby driving the height measuring member 42 to descend, when the information sensed by the height measuring member 42 changes suddenly, such as the distance between the height measuring member 42 and the container changes suddenly, the control member 5 records the corresponding information of the driving member 41 at this time, obtains the movement distance of the height measuring member 42, and obtains the height of the container. At the same time, the liquid level detection member 3 works, so as to obtain the liquid level in the container; when the liquid level in the container / the height of the container is greater than or equal to the first threshold value, the control member 5 controls the electromagnetic valve 2 to close the water outlet 121, so as to prevent water from overflowing out of the container.

[0070] The height measuring member 42 can continue to descend until the height measuring member 42 senses the first signal shielding member 431 and sends a back-and-forth signal, and the control member 5 controls the driving member 41 to make the height measuring member 42 move reversely to the initial position when the back-and-forth signal is received. When the height measuring member 42 rises to sense the second signal shielding member 432 and sends a stop signal to indicate resetting to the initial position, the control member 5 controls the driving member 41 to make the height measuring member 42 stop at the initial position, thereby completing the automatic resetting function.
