Abstract
Description
Technical Field
[0001] The utility model relates to the field of drinking water equipment, in particular to drinking water equipment. Background Art
[0002] In current drinking water equipment that can automatically supply water, such as tea bar machines, two water level detection probes are usually set in the kettle, one for detecting whether the liquid in the kettle has reached the highest water level, and the other for detecting whether the liquid in the kettle has reached the lowest water level. However, this water level detection method is costly, and both water level detection probes need to be connected to the power supply through the power coupler at the bottom of the kettle, which will increase the number of cores of the power coupler to 7 or even more, greatly reduce the electrical clearance, increase the difficulty of 3C certification, and even cause non-compliance with standards. Utility Model Content
[0003] Therefore, the purpose of the present invention is to provide a drinking water device to at least solve one of the problems existing in the above-mentioned prior art or related technology.
[0004] One aspect of an embodiment of the utility model provides a drinking water device, which includes: a container body, which is used to hold liquid, and the bottom of the container body has a heating plate and an upper coupler electrically connected to the heating plate; a container base, the top of the container base has a lower coupler, and the lower coupler can be coupled and connected with the upper coupler; a support platform, on which an elastic support member is arranged, and the elastic support member elastically supports the container base so that the container base can move up and down according to the liquid level change of the liquid in the container body; a detection device, which is arranged below the container base, and the detection device is used to detect the position change of the container base, and generate a corresponding detection signal according to the position change of the container base.
[0005] The drinking water equipment provided by the embodiment of this aspect utilizes an elastic support member to elastically support the container base on the support platform, so that the container base can naturally move up and down according to the change of the liquid level in the container body. For example, when there is more liquid in the container body, the container base will naturally be pressed down greatly under the action of gravity. When there is less liquid in the container body, the container base can be pressed down slightly or even not at all. The position change of the container base can accurately reflect the liquid level in the container body. In this case, a detection device is used to detect the position of the container base to reflect the liquid level in the container body, thereby realizing the detection of the liquid level height in the container body. Moreover, the detection device is arranged below the container base, which is convenient for powering on the detection device without using the upper coupler and the lower coupler, thereby eliminating the need to add chips to the upper coupler and the lower coupler, which is conducive to making the electrical clearance of the upper and lower couplers meet the relevant requirements and the wiring is more reasonable.
[0006] In some embodiments, the detection device includes a detection circuit, and when the container base is in different positions, it can trigger the detection circuit to be turned on or off, thereby generating a detection signal corresponding to the on-off state of the detection circuit.
[0007] In these embodiments, the position of the container base is reflected by the on-off state of the detection circuit, and the liquid level in the container body is then known. The detection circuit is directly triggered by the moving container base, and the detection circuit can timely and accurately reflect the position of the container base, thereby reflecting the measured liquid level. Moreover, compared with the detection device using a sensor, the detection circuit is low-cost.
[0008] In some embodiments, when the liquid in the container is lower than the first set liquid level, the base of the container moves up under the elastic force of the elastic support, triggering the detection circuit to be in the first on-off state, and generating a detection signal indicating that the liquid is at a low water level. When the liquid in the container reaches the second set liquid level, the base of the container moves down, triggering the detection circuit to be in the second on-off state, and generating a detection signal indicating that the liquid is at a high water level. This is beneficial for the detection circuit to detect whether the liquid in the container is too low or has reached the set liquid level. This makes it convenient for the drinking water equipment to supply water to the container according to the detection signal sent by the detection circuit, or stop supplying water, to avoid dry burning or overflow.
[0009] In some embodiments, the detection circuit includes: a first conductive member, which is arranged at the bottom of the container base; a second conductive member, which is arranged on a support platform and is located on the moving path of the first conductive member; when the detection circuit is in one of a first on-off state and a second on-off state, the first conductive member and the second conductive member are in contact, and when the detection circuit is in another state, the first conductive member and the second conductive member are separated.
[0010] In these embodiments, the detection circuit includes a first conductive member and a second conductive member, wherein the first conductive member can move synchronously with the container base, so as to contact or separate from the second conductive member as the position of the container base changes, thereby connecting or disconnecting the detection circuit. The connection and disconnection of the detection circuit can generate different detection signals, thereby reflecting the liquid level. The detection circuit has a simple structure and high reliability.
[0011] In some embodiments, the detection device also includes: a first limit member, which is arranged on the container base; a second limit member, which is arranged on the support platform and is used to cooperate with the first limit member to limit the upward movement of the container base; a driving assembly, which is used to release the limit cooperation between the first limit member and the second limit member; wherein, when the liquid in the container body is lower than the first set liquid level height, the elastic support member overcomes the limit of the second limit member on the first limit member and pushes the container base to move upward, releasing the limit cooperation between the first limit member and the second limit member; when the liquid in the container body reaches the second set liquid level height, the first limit member and the second limit member are limited and cooperated, and the detection circuit is in the second on-off state; when the liquid in the container body is higher than the first set liquid level height and lower than the second set liquid level height, and the first limit member and the second limit member are limited and cooperated, the mutual cooperation between the first limit member and the second limit member can limit the upward movement of the container base, and the detection circuit is in the second on-off state.
[0012] In these embodiments, the detection device further includes a first limiter and a second limiter, and the two limiters cooperate with each other to cooperate with the detection circuit to jointly detect the position of the container base. Specifically, when the liquid in the container body is lower than the first set liquid level height, the amount of liquid in the container body is small and the weight is light, so that the elastic support member can overcome the limitation of the second limiter on the first limiter and push the container base to move upward, so that the detection circuit is in the first on-off state, ensuring that the detection circuit can generate a detection signal indicating that the liquid is at a low water level.
[0013] When the liquid in the container reaches the second set liquid level height, due to the cooperation of the two limit members, the container base will not move up and down significantly. On the one hand, it can prevent the detection signal generated by the detection circuit from being erroneously changed due to the floating of the container base. On the other hand, it can also prevent the container base from floating significantly when the subsequent heating plate heats the liquid in the container, thereby improving safety.
[0014] When the liquid in the container is higher than the first set liquid level and lower than the second set liquid level, and the first limiter and the second limiter cooperate, the amount of liquid in the container will not be too little and will not reach the highest liquid level, so that the second limiter overcomes the elastic force of the elastic support to limit the upward movement of the first limiter, thereby placing the detection circuit in the second on-off state. At this time, the drinking water device will determine that the liquid in the container has reached the "second set liquid level" based on the detection circuit, and generate a detection signal indicating that the liquid is in "high water". This design is beneficial during the use of the container, for example, when the user drinks the liquid in the container intermittently, the container base will not float up and down, making it convenient for the user to place the container on a relatively stable container base, thereby improving the user experience.
[0015] In some embodiments, the drive component can drive the first limit member to move or the second limit member to move or the container base to move upward to release the limiting cooperation between the first limit member and the second limit member so that the detection circuit is in the first on-off state, and the drive component can also be reset.
[0016] In these embodiments, when the drinking water device is in use, there may be water in the container body, and the water level is higher than the first set liquid level height, but lower than the second set liquid level height. When the user observes that the amount of water in the container body is insufficient, in order to meet the demand for drinking a large amount of water, the user may actively start the water supply module of the drinking water device to fill the container body with water. In this case, since the detection circuit is in the second on-off state at this time, the drinking water device will determine that the liquid in the container body has reached the "second set liquid level height" based on the detection circuit, and may not start the water supply module. Moreover, even if the water supply module is started, since the first limiter and the second limiter cooperate with each other to limit the movement of the container base, the detection circuit cannot continue to detect the liquid situation in the container body. Therefore, the detection device is also equipped with a driving component, so that when the drinking water equipment receives an instruction from the user to actively start the water supply module, the driving component first drives the first limit member and the second limit member to release the limit matching relationship through the driving component, so that the container base can move upward under the elastic force of the elastic support member, and restore the ability to move up and down according to the change of the liquid level in the container body. In this case, although the liquid in the container body is currently at a level greater than the first set liquid level and lower than the second set liquid level, the container base will move upward under the elastic force of the elastic support member because it is not affected by the first limit member and the second limit member, so that the detection circuit is in the first on-off state, and then the water supply module is started to add water until the liquid in the container body reaches the second set liquid level height, and the detection circuit is in the second on-off state, which is conducive to realizing the function of automatic water addition of the drinking water equipment when there is some water in the container body.
[0017] Moreover, if the driving assembly is able to reset, it can be reset after the container base regains the ability to move up and down according to the change of the liquid level in the container body, and will no longer affect the secondary limiting cooperation of the first limiting member and the second limiting member, which is beneficial for the first limiting member and the second limiting member to be limited and matched together again when the liquid in the container body reaches the second set liquid level height.
[0018] In some embodiments, the detection circuit also includes: a third conductive member, which is arranged on a support platform, and the first conductive member is capable of moving between the second conductive member and the third conductive member; wherein, when the detection circuit is in a first on-off state, one of the second conductive member and the third conductive member is in contact with the first conductive member, and the other is separated from the first conductive member, and when the detection circuit is in a second on-off state, the connection relationship between the first conductive member and the second conductive member and the third conductive member is opposite to that when the detection circuit is in the first on-off state.
[0019] In these embodiments, the detection circuit also includes a third conductive member, and the third conductive member and the second conductive member are distributed up and down. When the liquid in the container is lower than the first set height, the detection circuit is in the first on-off state. At this time, the first conductive member can contact one of the second conductive member and the third conductive member and separate from the other. When the liquid in the container reaches the second set height, the detection circuit is in the second on-off state. At this time, the on-off state of the first conductive member and the second conductive member and the third conductive member is just opposite to the first on-off state, which is conducive to the detection circuit accurately judging the liquid level of the liquid in the container according to the connection state between the first conductive member, the second conductive member and the third conductive member, and can avoid dry burning and liquid overflow. Moreover, if the first conductive member is not in contact with the second conductive member and the third conductive member, it can be accurately judged that the liquid in the container is higher than the first set height and lower than the second set height, and the liquid level detection is accurate. Moreover, the detection device has a simple structure and is low in cost compared with the use of two liquid level sensors in the related art.
[0020] In some embodiments, the detection device is a distance sensor. The distance sensor is arranged below the container base to detect the distance between the container base and the container base, thereby reflecting the downward movement of the container base, and then reflecting the height of the liquid level in the container. The integrated distance sensor takes up little space and is not prone to line disorder. Moreover, compared with the use of two water level sensors to detect the water level in the related art, only one distance sensor can be used to detect whether the liquid in the container is lower than the first set liquid level or reaches the second set liquid level, thereby reducing parts and saving costs.
[0021] In some embodiments, the drinking water device further includes: a water supply module for supplying water to the container; a controller electrically connected to the water supply module and the detection circuit, the controller can control the water supply module to supply water when the detection circuit is in a first on-off state, and the controller can also control the water supply module to stop supplying water when the detection circuit is in a second on-off state. Dry boiling or liquid overflow can be avoided.
[0022] In some embodiments, one of the first stopper and the second stopper includes an elastic buckle structure, and the other includes a buckle portion for the elastic buckle structure to be inserted. The structure is simple and easy to process. Moreover, the elastic buckle structure can be kept inserted into the buckle portion by its own elastic force, so that the two can be prevented from being easily separated.
[0023] In some embodiments, a hollow column is provided at the bottom of the container base, a through hole is provided on the side wall of the hollow column, the elastic buckle structure includes a compression spring placed horizontally in the hollow column and a protrusion located at one end of the compression spring, the side of the protrusion away from the compression spring has an arc-shaped guide surface, and the protrusion can extend out of the through hole under the elastic force of the compression spring. A sleeve is provided on the support platform, the buckle portion is a plug hole provided on the side wall of the sleeve, the inner diameter of the sleeve is larger than the outer diameter of the hollow column, so that the hollow column can be movably inserted into the sleeve, and the protrusion can extend into the plug hole to cooperate with the plug hole in a limited position.
[0024] In these embodiments, the hollow column can be inserted into the sleeve and move up and down in the sleeve. The cooperation between the hollow column and the sleeve can limit the container base to move up and down relatively smoothly, avoid the container base from tilting significantly, and thus ensure the stability of the container body. In addition, the elastic buckle structure is arranged in the hollow column, and a plug hole is arranged on the side wall of the sleeve for the elastic buckle structure to be inserted. While the structure is compact, the elastic buckle structure can be moved along the set path limited by the sleeve, which is conducive to the accurate insertion of the elastic buckle structure into the plug hole. In addition, the elastic buckle structure includes a compression spring, one end of the compression spring abuts against the inner side wall of the hollow column, and the other end of the compression spring is connected to the protrusion, so that the side of the protrusion away from the compression spring has an arc-shaped guide surface, which facilitates the protrusion to smoothly enter or move out of the plug hole without getting stuck.
[0025] In some embodiments, the first conductive member is disposed at the bottom of the hollow column, and the second conductive member is disposed inside the sleeve. The structure is compact, and the first conductive member is separated from the surrounding components by the hollow column, and the second conductive member is separated from the surrounding components by the sleeve, which can reduce the risk of leakage.
[0026] In some embodiments, a through hole connected to the interior of the sleeve is provided on the support platform, and the driving assembly includes a driving member and a push rod. The push rod extends into the through hole. The driving member can drive the push rod to move upward to push the hollow column, thereby driving the container base to move upward. The driving member can also drive the push rod to move downward and reset.
[0027] In these embodiments, the driving assembly includes a driving member and a push rod, so that the push rod passes through the through hole at the bottom of the sleeve and pushes the hollow column upward, thereby driving the elastic buckle structure on the container base and the hollow column to move upward, so that the elastic buckle structure is separated from the insertion hole, and the first limit member and the second limit member are released from the limit matching relationship. Compared with setting a through hole at a position avoiding the sleeve on the support platform so that the push rod can directly contact the bottom wall of the container base upward, the push rod does not need to be too long, and the structure is compact. In addition, the driving member can drive the push rod to move down and reset. After the push rod moves down, even if the container base moves down again to drive the first limit member to move down, it will not interfere with the push rod, so that it can be limited and matched with the second limit member again.
[0028] In some embodiments, the drinking water device further comprises a workbench, a portion of which is sunken downward to form a groove, and the bottom wall of the groove is configured as a support platform. The container base can be moved downward to be flush with the workbench. The support platform and the workbench are an integrated structure, and the support platform is firmly connected, which is conducive to stably supporting the container base and the container body. The groove sidewall of the groove can also shield the elastic support member in the lateral direction, thereby improving the appearance of the product.

[0055] The following will be combined Figures 1 to 7 The drinking water equipment provided by the embodiment of the utility model is introduced.
[0056] like Figure 1 , Figure 2 and Figure 3As shown, one aspect of an embodiment of the utility model provides a drinking water device, which includes: a container body 10, used to hold liquid, the bottom of the container body 10 is provided with a heating plate 110 and an upper coupler 120 electrically connected to the heating plate 110; a container base 20, the top of the container base 20 is provided with a lower coupler 220, and the lower coupler 220 can be coupled and electrically connected to the upper coupler 120; a support platform 30, the support platform 30 is provided with an elastic support member 40, the elastic support member 40 elastically supports the container base 20, so that the container base 20 can move up and down according to the liquid level change of the liquid in the container body 10; a detection device, arranged below the container base 20, the detection device is used to detect the position change of the container base 20, and generate a corresponding detection signal according to the position change of the container base 20.
[0057] The drinking water equipment provided by the embodiment of this aspect uses the elastic support member 40 to elastically support the container base 20 on the support platform 30, so that the container base 20 can move up and down under the action of gravity according to the change of the liquid level in the container body 10. For example, when there is more liquid in the container body 10, the container base 20 will be greatly pressed down under the action of gravity. When there is less liquid in the container body 10, the container base 20 can be slightly pressed down or even not pressed down. The position change of the container base 20 can accurately reflect the liquid level in the container body 10. In this case, the position of the container base 20 is detected by the detection device to reflect the liquid level in the container body 10, thereby realizing the detection of the height of the liquid level in the container body 10. Moreover, the detection device is arranged below the container base 20, which is convenient for powering on the detection device without using the upper coupler 120 and the lower coupler 220, thereby eliminating the need to add chips to the upper coupler 120 and the lower coupler 220, which is conducive to making the electrical clearance of the upper and lower couplers 220 meet the relevant requirements and the wiring is more reasonable.
[0058] Furthermore, the drinking water equipment also includes a water supply module and a controller. The water supply module is used to supply water to the container body 10. The controller is electrically connected to the water supply module and the detection device. The controller can control the start and stop of the water supply module according to the detection signal generated by the detection device.
[0059] There may be many specific structures of the detection device.
[0060] Furthermore, in some embodiments, Figure 3 As shown, the detection device includes a detection circuit 50 linked to the container base 20. The container base 20 can trigger the detection circuit 50 to be turned on or off when it is in different positions, thereby generating a detection signal corresponding to the on-off state of the detection circuit 50.
[0061] The position of the container base 20 is reflected by the on-off state of the detection circuit 50, and then the liquid level height in the container body 10 is known. The detection circuit 50 is directly mechanically triggered by the moving container base 20. The detection circuit 50 can timely and accurately reflect the position of the container base 20, thereby reflecting the measured liquid level height.
[0062] Furthermore, when the liquid in the container body 10 is lower than the first set liquid level height, the container base 20 moves upward under the elastic force of the elastic support member 40, triggering the detection circuit 50 to be in the first on-off state, and generating a detection signal indicating that the liquid is at a low water level. When the liquid in the container body 10 reaches the second set liquid level height, the container base 20 moves downward, triggering the detection circuit 50 to be in the second on-off state, and generating a detection signal indicating that the liquid is at a high water level. The detection circuit 50 detects whether the liquid in the container body 10 is too low or reaches the set liquid level, so that the drinking water device can supply water to the container body 10 or stop supplying water according to the detection signal sent by the detection circuit 50, thereby avoiding dry burning or overflow.
[0063] The controller is electrically connected to the water supply module and the detection circuit 50. The controller can control the water supply module to supply water when the detection circuit 50 is in a first on-off state. The controller can also control the water supply module to stop supplying water when the detection circuit 50 is in a second on-off state.
[0064] In a specific application, the first set liquid level height may be the minimum liquid level height, and the second set liquid level height may be the rated liquid level height. When the detection circuit 50 is in the first on-off state, the controller may determine that there is less liquid in the container body 10, thereby controlling the water supply module to supply water to the container body 10 to avoid subsequent dry burning. The controller may also determine that there is more liquid in the container body 10 when the detection circuit 50 is in the second on-off state, and control the water supply module not to supply water to the container body 10, thereby avoiding overflow. As an example, the first on-off state may be that the detection circuit is in an off state, and the second on-off state may be that the detection circuit is in an on state, and vice versa.
[0065] It should be noted that the change in the on-off state of the detection circuit 50 will naturally generate a corresponding change in the electrical signal, and the generated electrical signal can be used as a detection signal.
[0066] As a first embodiment of the detection circuit 50, Figure 3As shown, the detection circuit 50 includes a first conductive member 510 and a second conductive member 520, wherein the first conductive member 510 is disposed at the bottom of the container base 20, and the second conductive member 520 is disposed on the support platform 30, located above the second conductive member 520 and located on the moving path of the first conductive member 510. When the liquid in the container body 10 is lower than the first set liquid level height, the detection circuit 50 is in a first on-off state, and the first conductive member 510 and the second conductive member 520 are separated. When the liquid in the container body 10 reaches the second set liquid level height, the detection circuit 50 is in a second on-off state, and the first conductive member 510 and the second conductive member 520 are in contact. In this case, the first on-off state indicates that the detection circuit 50 is in a disconnected state, and the second on-off state indicates that the detection circuit is in a conducting state.
[0067] Here, the detection circuit 50 includes a first conductive member 510 and a second conductive member 520, wherein the first conductive member 510 can move synchronously with the container base 20, so as to contact or separate from the second conductive member 520 as the position of the container base 20 changes, thereby turning on or off the detection circuit 50. The on and off of the circuit can generate different detection signals, thereby reflecting the liquid level situation. The detection circuit 50 has a simple structure and high reliability.
[0068] Here, the second set liquid level height can be made the maximum water filling height or the rated liquid level height of the container, so that the detection circuit 50 can accurately detect whether the liquid level in the container body 10 has reached the rated liquid level height, and the drinking water equipment can timely control the water supply module to stop providing liquid in time to avoid liquid overflow.
[0069] The controller can control the water supply module to supply water when the first conductive member 510 and the second conductive member 520 are separated, thereby preventing the container body 10 from drying out due to insufficient liquid. The controller can also control the water supply module to stop supplying water when the first conductive member 510 and the second conductive member 520 are in contact, thereby preventing liquid from overflowing.
[0070] like Figure 3 and Figure 5As shown, the detection device also includes a first limiter 610 and a second limiter 620. The first limiter 610 is arranged on the container base 20, and the second limiter 620 is arranged on the support platform 30, and can cooperate with the first limiter 610 to limit the first limiter 610 from moving upward, thereby limiting the container base 20 from moving upward. Wherein, when the liquid in the container body 10 is lower than the first set liquid level height, the elastic support member 40 can overcome the limit of the first limiter 610 by the second limiter 620 and push the container base 20 upward, so as to release the limit cooperation of the first limiter 610 and the second limiter 620. When the liquid in the container body 10 reaches the second set liquid level height, the container base 20 moves downward, so that the first limiter 610 and the second limiter 620 are limited again, and the detection circuit 50 is in the second on-off state. When the liquid in the container body 10 is higher than the first set liquid level height and lower than the second set liquid level height, and the first limit member 610 and the second limit member 620 cooperate with each other, the mutual cooperation of the first limit member 610 and the second limit member 620 can overcome the elastic force of the elastic support member 40 to limit the upward movement of the container base 20, and the detection circuit 50 is in the second on-off state.
[0071] When the liquid in the container body 10 is lower than the first set liquid level height, the amount of liquid in the container body 10 is small and the weight is light, so that the elastic support member 40 can overcome the limitation of the second limiting member 620 on the first limiting member 610 and push the container base 20 upward, so that the detection circuit 50 is in the first on-off state, ensuring that the detection circuit 50 can generate a detection signal indicating that the liquid is at a low water level.
[0072] When the liquid in the container body 10 reaches the second set liquid level height, the liquid in the container body 10 is relatively large, for example, it reaches the rated liquid level height, and the weight is relatively heavy, which will press down the container base 20, thereby driving the first limit member 610 to move down to cooperate with the second limit member 620. At the same time, the first conductive member 510 is triggered to contact the second conductive member 520, so that the detection circuit 50 generates a detection signal indicating that the liquid is at a high water level. Due to the limited cooperation of the two limit members, the container base 20 will not move up and down significantly. On the one hand, it can prevent the detection signal generated by the detection circuit 50 from being erroneously changed due to the floating of the container base 20. On the other hand, it can also prevent the container base 20 from floating significantly when the subsequent heating plate 110 heats the liquid in the container body 10, resulting in poor contact, thereby improving safety.
[0073] When the liquid in the container body 10 is higher than the first set liquid level height and lower than the second set liquid level height, and the first limiter 610 and the second limiter 620 are in position-limiting cooperation, at this time, although the amount of liquid in the container body 10 does not reach the highest liquid level, the amount of liquid will not be very small. In this state, the elastic support member 40 is not enough to overcome the force of the first limiter 610 on the second limiter 620, so that the first limiter 610 and the second limiter 620 remain in the position-limiting cooperation state to prevent the container base 20 from moving up. At this time, the detection circuit 50 is in the second on-off state, and the automatic water adding operation will not be started. Since the amount of liquid in the container body 10 is not very small, even if the user starts the heating operation, there will be no risk of dry burning. Moreover, this design is beneficial to the use of the container body 10. For example, when the user drinks the liquid in the container body 10 intermittently, although the liquid is less than the rated water volume, the container base 20 will not float up and down, so that it is convenient for the user to place the container body 10 on a relatively stable container base 20, thereby improving the user experience.
[0074] like Figure 3 As shown, the detection device further includes a driving assembly 70, which can drive the first stopper 610 to move or the second stopper 620 to move or the container base 20 to move upward, so as to release the stopper cooperation between the first stopper 610 and the second stopper 620, so as to put the detection circuit 50 in the first on-off state, thereby starting the automatic water adding operation. After driving the container base 20 to move upward, the driving assembly 70 can also be reset.
[0075] During the use of the drinking water device, there may be a situation where there is water in the container body 10, and the water level is higher than the first set liquid level height, but lower than the second set liquid level height. If the user believes that the amount of water in the container body 10 does not meet the demand for a large amount of drinking water, he may actively start the water supply module of the drinking water device and want to add water to the container body 10. In this case, since the detection circuit 50 is in the second on-off state instead of the first on-off state, the automatic water adding function cannot be triggered. Therefore, in order to change the detection circuit 50 to the first on-off state, according to one aspect of this embodiment, a driving component 70 is further provided. When the drinking water device receives the water adding instruction input by the user, the driving component 70 first drives the first limiter 610 and the second limiter 620 to release the limit matching relationship, so that the container base 20 can move up under the elastic force of the elastic support member 40, so that the first conductive member 510 and the second conductive member 520 are separated, triggering the detection circuit 50 to generate a detection signal of the first on-off state. In this case, although the liquid in the container body 10 is currently at a level greater than the first set liquid level and lower than the second set liquid level, since the detection circuit 50 is in the first on-off state, the controller can automatically start the water supply module to add water until the liquid in the container body 10 reaches the second set liquid level, and the container base 20 falls again under the action of gravity, so that the first conductive member 510 and the second conductive member 520 are restored to the contact state, and the detection circuit 50 is in the second on-off state, and the water addition stops. By setting the drive assembly 70, it is possible to meet the user's need to add water when there is some water in the container body 10.
[0076] In addition, the drive assembly 70 can also be reset. After the container base 20 moves up and the first limit member 610 and the second limit member 620 are released from the limit fit, the drive assembly 70 is reset, which is conducive to the first limit member 610 and the second limit member 620 being limitedly matched together again when the liquid in the container body 10 reaches the second set liquid level height, thereby avoiding the drive assembly 70 from hindering the first limit member 610 and the second limit member 620 from matching again due to failure to reset.
[0077] The first limiting member 610 and the second limiting member 620 are arranged vertically. When the first limiting member 610 moves downward to the position where the second limiting member 620 is located along with the container base 20 , the first limiting member 610 can cooperate with the second limiting member 620 in a limiting manner.
[0078] The driving assembly 70 can drive the first limiting member 610 to move upward, temporarily separating it from the second limiting member 620, and releasing the limiting cooperation relationship between the two. Then, the driving assembly 70 can be reset away from the first limiting member 610, and the first limiting member 610 can move downward again with the container base 20 to cooperate with the second limiting member 620.
[0079] The driving assembly 70 can also drive the first stopper 610 to move horizontally, temporarily separating it from the second stopper 620, and releasing the stopper matching relationship between the two. Then, the driving assembly 70 can be reset away from the first stopper 610, so that the first stopper 610 can be reset under its own elastic force, so as to facilitate the subsequent stopper matching with the second stopper 620 again as the container base 20 moves downward.
[0080] The driving assembly 70 can also directly drive the container base 20 to move upward, thereby driving the first limiting member 610 to move upward, temporarily separating it from the second limiting member 620, and releasing the limiting cooperation relationship between the two. Then, the driving assembly 70 can be reset away from the container base 20, and the first limiting member 610 can move downward again with the container base 20 to cooperate with the second limiting member 620.
[0081] The controller can also be electrically connected to the drive component 70. When the detection circuit 50 is in the second on-off state and after receiving a water-adding instruction actively input by the user, the controller can control the drive component 70 to drive the first limit member 610 and the second limit member 620 to release the limit cooperation, so that the detection circuit 50 is in the first on-off state. Then, the controller starts the water supply module to supply water until the detection circuit 50 is in the second on-off state again.
[0082] Below, a specific structural example of the first limiting member 610, the second limiting member 620 and the driving assembly 70 according to an embodiment of the present application is described in detail.
[0083] The first stopper 610 includes an elastic buckle structure, and the second stopper 620 includes a buckle portion for the elastic buckle structure to be inserted into. The elastic buckle structure can be inserted into the buckle portion according to its own elastic force, so that the two can be prevented from being easily separated. The structure is simple and easy to process.
[0084] A specific embodiment 1 of the first limiting member 610 , the second limiting member 620 and the driving assembly 70 is described below.
[0085] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, a hollow column 230 is provided at the bottom of the container base 20, and a through hole is provided on the side wall of the hollow column 230. The elastic buckle structure includes a compression spring 611 horizontally placed in the hollow column 230 and a protrusion 612 located at one end of the compression spring 611. The protrusion 612 has an arc-shaped guide surface on the side away from the compression spring 611, and the protrusion 612 can extend out of the through hole under the elastic force of the compression spring 611. A sleeve 330 is provided on the support platform 30, and the buckle portion is a plug hole provided on the side wall of the sleeve 330. The inner diameter of the sleeve 330 is larger than the outer diameter of the hollow column 230, so that the hollow column 230 can be movably inserted into the sleeve 330, and the protrusion 612 can extend into the plug hole to cooperate with the plug hole in a limited position.
[0086] Here, the hollow column 230 can be extended into the sleeve 330 and move up and down in the sleeve 330, which has a motion guiding effect. The cooperation between the hollow column 230 and the sleeve 330 can limit the container base 20 to move up and down relatively smoothly, avoid the container base 20 from tilting significantly, and thus ensure the stability of the container body 10. In addition, the elastic buckle structure is arranged in the hollow column 230, and a socket is arranged on the side wall of the sleeve 330 for the elastic buckle structure to be inserted. While the structure is compact, the elastic buckle structure can be moved along the set path limited by the sleeve 330, so as to facilitate the accurate insertion of the elastic buckle structure into the socket. In addition, the elastic buckle structure includes a compression spring 611, one end of the compression spring 611 abuts against the inner side wall of the hollow column 230, and the other end of the compression spring 611 is connected to the protrusion 612, so that the side of the protrusion 612 away from the compression spring 611 has an arc-shaped guide surface, which facilitates the protrusion 612 to smoothly enter or move out of the socket without getting stuck.
[0087] The projection 612 may be a spherical block with a spherical surface, which is convenient for insertion and removal from the socket. The projection 612 may also be a square block, as long as the insertion side has an arc-shaped guide surface.
[0088] like Figure 3 and Figure 7 As shown, the driving assembly 70 includes a driving member 710 and a push rod 720. The driving member 710 can be a driving motor or an electromagnetic push rod or a cylinder or a hydraulic cylinder. For example, the driving member 710 is a stepping motor. The driving member 710 can be other components that can generate driving force, and is not limited to the above embodiments.
[0089] like Figure 3As shown, the support platform 30 is provided with a through hole 310 connected to the inside of the sleeve 330, and the push rod 720 extends into the through hole 310. The driving member 710 drives the push rod 720 to move upward to push the hollow column 230, thereby driving the container base 20 to move upward, and the driving member 710 can also drive the push rod 720 to move downward and reset. Compared with setting the through hole 310 at a position to avoid the sleeve 330 on the support platform 30 so that the push rod 720 can directly contact the bottom wall of the container base 20 upward, there is no need to make the push rod 720 too long, and the structure is compact. In addition, the driving member 710 can drive the push rod 720 to move downward and reset. After the push rod 720 moves downward, when the container base 20 moves downward again to drive the first stopper 610 to move downward, it will not interfere with the push rod 720, so that the first conductive member 510 and the second conductive member 520 can contact each other, and it is convenient for the first stopper 610 to cooperate with the second stopper 620 again.
[0090] In addition, if Figure 3 As shown, the first conductive member 510 is arranged at the bottom of the hollow column 230, and the second conductive member 520 is arranged inside the sleeve 330. The structure is compact, and the first conductive member 510 is separated from the surrounding components by the hollow column 230, and the second conductive member 520 is separated from the surrounding components by the sleeve 330, which can reduce the risk of leakage.
[0091] Specifically, the lower end of the hollow column 230 is blocked, and the first conductive member 510 is arranged at the bottom of the hollow column 230. The first conductive member 510 may include a protruding contact. The second conductive member 520 is arranged at the top of the top rod 720, and the second conductive member 520 may be a protruding contact or an elastic electrode sheet. When the driving member 710 drives the top rod 720 to move upward, the top rod 720 lifts the hollow column 230, and then the container base 20 moves upward under the elastic force of the elastic support member 40, and the first limit member 610 and the second limit member 620 release the limit cooperation, and the first conductive member 510 and the second conductive member 520 are separated. After the top rod 720 is reset, the second conductive member 520 located at the top of the top rod 720 is also reset, so that the detection circuit 50 is in a disconnected state, and a first on-off state signal is generated, and the automatic water adding function can be started at this time.
[0092] A second specific embodiment of the first limiting member 610 , the second limiting member 620 and the driving assembly 70 is described below.
[0093] The main difference from the above-mentioned specific embodiment 1 is that the through hole 310 is arranged on the support platform 30 at a position far away from the sleeve 330. At this time, the push rod 720 passes through the through hole 310 and directly contacts the container base 20, thereby lifting the container base 20. The advantage of this design is that the through hole 310 and the drive assembly 70 have a larger setting area, which facilitates the reasonable arrangement of the positions of the through hole 310 and the drive assembly 70.
[0094] A third specific embodiment of the first limiting member 610 , the second limiting member 620 , and the driving assembly 70 is described below.
[0095] The main difference from the above-mentioned specific embodiment 1 is that the hollow column 230 and the sleeve 330 structure are eliminated, and the first stopper 610 and the second stopper 620 are changed. The outer periphery of the container base 20 has a flange structure extending downward (not shown in the figure), and the drinking water device also includes a workbench 80, a part of the workbench 80 is recessed downward to form a groove 810, and the bottom wall of the groove 810 is configured as a support platform 30. One of the first stopper 610 and the second stopper 620 is arranged on the flange structure, and the other is arranged on the groove side wall of the groove 810. Here, the groove 810 can also limit the movement of the container base 20, so as to achieve an effect similar to that of the hollow column 230 being movably inserted into the sleeve 330.
[0096] A fourth specific embodiment of the first position-limiting member 610 , the second position-limiting member 620 , and the driving assembly 70 is described below.
[0097] The main difference from the above-mentioned specific embodiment 2 is that the structures of the first limit member 610 and the second limit member 620 are different. One of the first limit member 610 and the second limit member 620 can be a pit (not shown in the figure), and the other can be an elastic convex bump (not shown in the figure). The elastic convex bump is made of rubber or other materials and has elasticity itself without relying on the compression spring 611.
[0098] A fifth specific embodiment of the first limiting member 610 , the second limiting member 620 and the driving assembly 70 is described below.
[0099] The main difference from the above-mentioned specific embodiment 1 is that the driving assembly 70 drives the first limiting member 610 to move horizontally to release the limiting cooperation between the first limiting member 610 and the second limiting member 620. For example, the driving assembly 70 can pull the protrusion 612 horizontally away from the socket, and after the driving assembly 70 is reset, the protrusion 612 is reset under the elastic force of the compression spring 611. As for the specific structure and setting position of the driving assembly 70 in this case, the driving assembly 70 can be set on one side of the horizontal direction of the first limiting member 610, and the protrusion 612 can be set as a metal part. The driving assembly 70 electromagnetically attracts the protrusion 612 to make it separate from the socket, so that the driving assembly 70 will not directly contact the protrusion 612 and will not affect the subsequent up and down movement of the container base 20. Alternatively, the drive assembly 70 can be set inside the hollow column 230 and can move synchronously with the container base 20. In this way, after the drive assembly 70 drives the protrusion 612 to disengage from the socket, even if the container base 20 moves upward under the elastic force of the elastic support member 40, the container base 20 will not interfere with the drive assembly 70.
[0100] Next, a second embodiment of the detection circuit 50 will be described.
[0101] According to one aspect of the second embodiment of the detection circuit 50, a portion of the first conductive member 510 is bent over the second conductive member 520 so as to be located below the second conductive member 520. When the liquid in the container body 10 is lower than the first set liquid level, the container base 20 moves upward under the elastic force of the elastic support member 40, triggering the first conductive member 510 and the second conductive member 520 to contact each other, and the detection circuit 50 is in the first on-off state. When the liquid in the container body 10 reaches the second set liquid level, the container base 20 moves downward under the weight of the liquid, driving the first conductive member 510 downward away from the second conductive member 520, so that the first conductive member 510 and the second conductive member 520 are separated, and the detection circuit 50 is in the second on-off state.
[0102] Optionally, according to the first embodiment or the second embodiment of the detection circuit 50, the detection device may further include a third limiter, which is disposed on the support platform 30 and is used to cooperate with the first limiter 610 to limit the downward movement of the first limiter 610. When the liquid in the container body 10 is lower than the first set liquid level, the container base 20 drives the first limiter 610 to move upward and cooperate with the third limiter. When the liquid in the container body 10 reaches the second set liquid level, the container base 20 overcomes the limit of the first limiter 610 by the third limiter under the action of the weight of the liquid in the container body 10 and moves downward until the first limiter 610 cooperates with the second limiter 620, triggering the detection circuit 50 to be in the second on-off state.
[0103] For example, when the above-mentioned hollow column 230 is provided on the container base 20 and the above-mentioned sleeve 330 is provided on the support platform 30, the top edge of the sleeve 330 can be configured as the third stopper. After the protrusion 612 is removed from the insertion hole, it moves upward along the inner wall of the sleeve 330 and extends out of the sleeve 330, thereby engaging with the top edge of the sleeve 330 in a stoppered manner.
[0104] Next, a third embodiment of the detection circuit 50 will be described.
[0105] Compared with the first embodiment of the detection circuit 50, the main difference is that the detection circuit 50 also includes a third conductive member, and the first limit member 610, the second limit member 620 and the drive assembly 70 are eliminated. Specifically, the detection circuit 50 includes a first conductive member 510, a second conductive member 520 and a third conductive member, the first conductive member 510 is arranged at the bottom of the container base 20, the second conductive member 520 and the third conductive member are both arranged on the support platform 30 and are spaced apart from each other, and the first conductive member 510 can move between the second conductive member 520 and the third conductive member. When the detection circuit 50 is in the first on-off state, one of the second conductive member 520 and the third conductive member is in contact with the first conductive member 510, and the other is separated from the first conductive member 510. When the detection circuit 50 is in the second on-off state, the connection relationship between the first conductive member 510 and the second conductive member 520 and the third conductive member is opposite to that when the detection circuit 50 is in the first on-off state.
[0106] As an example, the third conductive member is located above the second conductive member 520, and the first conductive member 510 moves between the third conductive member and the second conductive member 520. When the liquid in the container body 10 is lower than the first set liquid level height, the first conductive member 510 and the third conductive member are in contact, the first conductive member 510 and the second conductive member 520 are separated, and the detection circuit 50 is in the first on-off state to generate a detection signal indicating that the liquid is at a low water level. At this time, it can be determined that the liquid level in the container body 10 is small. When the liquid in the container body 10 is higher than the first set liquid level height and lower than the second set liquid level height, the first conductive member 510 is not in contact with the second conductive member 520 and the third conductive member, the detection circuit 50 is in the third on-off state, and generates a detection signal indicating that the liquid is at a medium water level. At this time, it can be determined that the liquid level in the container body 10 is not full, but not too low. When the liquid in the container body 10 reaches the second set liquid level height, the first conductive member 510 and the third conductive member are separated, the first conductive member 510 and the second conductive member 520 are in contact, and the detection circuit 50 is in the second on-off state to generate a detection signal indicating that the liquid is at a high water level. At this time, it can be determined that the liquid in the container body 10 has reached the set quota liquid level.
[0107] The detection circuit 50 of this embodiment does not need to be equipped with the first limiter 610, the second limiter 620 and the driving assembly 70, so it has fewer parts, is easy to produce and process, and has low cost. Of course, due to the increase in detection circuits, the reasonable design of the circuit position must be considered.
[0108] It should be noted that the detection circuit 50 proposed in the present application mainly refers to a conductive member used to trigger the generation of a detection signal, and a corresponding wire needs to be provided to connect with the conductive member, which will not be elaborated in detail here.
[0109] In addition to using the detection circuit 50 to detect the liquid level, the detection device may also use other methods to detect the liquid level. Further, in other embodiments, the detection device is a distance sensor.
[0110] Here, the distance sensor disposed below the container base 20 is used to detect the distance between the container base 20 and the container base 20, thereby reflecting the downward movement of the container base 20, and further reflecting the height of the liquid level in the container body 10. The integrated distance sensor takes up little space and is not prone to line disorder. Moreover, compared with the use of two water level sensors to detect the water level in the related art, only one distance sensor can be used to detect whether the liquid in the container body 10 is lower than the first set liquid level or reaches the second set liquid level, thereby reducing parts and saving costs.
[0111] Furthermore, in some embodiments, Figure 3 , Figure 4 and Figure 6 As shown, there are multiple elastic support members 40 , and the multiple elastic support members 40 are distributed circumferentially around the center of the container base 20 , which is conducive to stably supporting the container base 20 .
[0112] As an example, Figure 3 , Figure 4 and Figure 6 As shown, the elastic support member 40 is a spring, and a spring limiting rod 210 is provided on the bottom of the container base 20 and one of the support platform 30, and a spring limiting cylinder 320 is provided on the other. The spring limiting rod 210 and the spring limiting cylinder 320 are relatively distributed up and down, and the inner diameter of the spring limiting cylinder 320 is larger than the outer diameter of the spring limiting rod 210, one end of the spring extends into the spring limiting cylinder 320, and the other end of the spring is sleeved on the spring limiting rod 210.
[0113] Of course, the number of the elastic support member 40 can also be one, such as an annular disc spring, which can also support the container base 20 over a large area.
[0114] Furthermore, in some embodiments, Figure 3 As shown, the drinking water device further includes a workbench 80, a portion of which is recessed downward to form a groove 810, and the bottom wall of the groove 810 is configured as a support platform 30. The support platform 30 and the workbench 80 are an integrated structure, and the support platform 30 is firmly connected, which is conducive to stably supporting the container base 20 and the container body 10. In addition, the groove sidewall of the groove 810 can also shield the elastic support member 40 in the lateral direction, thereby improving the appearance of the product.
[0115] Furthermore, if Figure 3As shown, the container base 20 can move downward and be flush with the workbench 80. For example, when the liquid in the container body 10 reaches the second set liquid level height, the container base 20 can be flush with the workbench 80. It is also acceptable to be roughly flush here. On the one hand, it is helpful for the user to directly understand the approximate liquid level height of the liquid in the container base 20 by observing the height difference between the two. On the other hand, the drinking water device can heat the liquid when the upper surface of the workbench 80 and the container base 20 are flush, which has a good appearance effect and improves the user experience.
[0116] Furthermore, in some embodiments, the detection device is disposed in the groove 810 , with a compact structure and beautiful appearance.
[0117] Furthermore, in some embodiments, the drinking water device further comprises an operating table located above the workbench 80, and a plurality of water spouts are provided below the operating table, wherein one of the water spouts is located above the container body 10 and is aligned with the container body 10. The drinking water device further comprises an additional water container, which is placed on the workbench 80 and can be aligned with any of the remaining water spouts.
[0118] Furthermore, in some embodiments, the container body 10 is an electric kettle.
[0119] Furthermore, in some embodiments, the drinking water device is a water dispenser, a tea bar machine or a coffee machine.
[0120] Below, a drinking water device according to an embodiment of the present application is described in detail by taking a tea bar machine as an example.
[0121] like Figures 1 to 3 As shown, the tea bar machine includes a workbench 80, an electric kettle, a kettle base, a water supply module, a controller and a detection device. The bottom of the electric kettle has a heating plate 110 and an upper coupler 120 electrically connected to the heating plate 110, and the kettle base has a lower coupler 220, which cooperates with the upper coupler 120 to energize and heat the electric kettle. The kettle base is set on the workbench 80, the detection device is used to detect the liquid level height in the electric kettle, and generate a detection signal reflecting the liquid level height, and the controller is used to control the start and stop of the water supply module according to the detection signal generated by the detection device.
[0122] like Figures 3 to 6 As shown, a groove 810 is provided on the workbench 80, and the bottom wall of the groove 810 serves as a support platform 30. A plurality of spring limiting cylinders 320 are provided on the support platform 30, and suitable springs are installed. A plurality of spring limiting rods 210 are provided at the bottom of the kettle base. The plurality of spring limiting rods 210 and the plurality of spring limiting cylinders 320 are distributed in a one-to-one correspondence. The bottom of the spring is inserted into the spring limiting cylinder 320, and the top is sleeved on the spring limiting rod 210. The kettle base is propped up by the spring, and the electric kettle is placed on the kettle base.
[0123] A sleeve 330 is provided in the middle of the support platform 30 , and a plug hole is provided on the side wall of the sleeve 330 , and the plug hole is used to limit the displacement of the kettle base.
[0124] A hollow column 230 is arranged at the center of the bottom wall of the container base 20, a through hole is arranged on the side wall of the hollow column 230, a compression spring 611 and a limiting ball are arranged in the hollow column 230, the compression spring 611 is horizontally arranged in the hollow column 230 corresponding to the position of the through hole, one end of the compression spring 611 is connected to the limiting ball, and the limiting ball can be inserted into the jack under the elastic force of the compression spring 611 to limit the movement of the kettle base. A base electrode (as the first conductive member 510) is arranged at the bottom of the hollow column 230.
[0125] like Figure 3 and Figure 7 As shown, the bottom of the sleeve 330 on the support platform 30 is provided with a through hole 310, and the driving assembly 70 includes a push rod 720 and a stepper motor. The push rod 720 extends into the through hole 310, and a spring electrode (as a second conductive member 520) is provided on the top of the push rod 720, which can contact the base electrode to form a loop. The push rod 720 can be driven by the stepper motor to push the limit ball out of the socket, so that the kettle base is out of the restriction of the socket.
[0126] When the water level in the electric kettle is lower than the minimum water level (the first set liquid level height), the elastic force of the spring will push the limit ball at the bottom of the kettle base out of the jack to the upper part of the sleeve 330, the base electrode is separated from the spring electrode, and the detection circuit 50 is disconnected. The system can determine that the water level in the electric kettle is low or there is no water, allowing automatic water adding operation.
[0127] When water is added to the electric kettle and reaches the maximum water level (the second set liquid level height), due to the increase in water weight, it will break through the upper limit of the limit ball on the sleeve 330, move down along the sleeve 330 into the socket, the base electrode contacts the spring electrode, and the circuit is connected. The system can determine that the water level inside the kettle has reached the maximum water level.
[0128] When the electric kettle is in use, if the water level is higher than the minimum water level and lower than the maximum water level, the limit ball is stuck in the socket, and the two electrodes are in contact. If the user activates the water adding function, the system will determine that the kettle is full of water. Therefore, when the user actively activates the water adding function, the stepper motor pushes the hollow column 230 upward through the top rod 720 to make the limit ball disengage from the socket, and then resets the top rod 720, and then water is added. This can realize the operation of adding water according to the user's active water adding request in the water state.

It should be understood that, in the opinion of those skilled in the art, these modifications and variations will still fall within the spirit and scope of the embodiments of the present invention as defined in the claims.
