[0003] A pipeline drinking water device in the related art has an automatic water replenishment function. If a water leakage accident occurs in this pipeline drinking water device, the consequences will be relatively serious and will cause relatively serious property losses. Therefore, it is necessary to consider the problem of water leakage prevention. Summary of the Utility Model

[0004] In view of the above situation, the utility model provides a pipeline drinking water device, aiming to reduce the risk of water leakage accidents.

According to the principle of the communicating vessel, the water in the balance water pipe and the water in the water tank have the same water level. In this way, during the process of replenishing water to the water tank, as the water level in the water tank rises, the water level in the balance water pipe also rises synchronously.

[0045] In order to make the objectives, technical solutions, and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0046] The pipeline drinking water device is also called a pipeline machine, a pipeline drinking fountain, etc., and is generally used in conjunction with a water purification device. The pipeline drinking water device is usually equipped with a water tank. The externally purified water enters the pipeline drinking water device and is stored in the water tank. The water stored in the water tank can be further heated, cooled, or provided to users at room temperature for the users to drink.

[0047] A pipeline drinking water device in the related art can automatically replenish water to a water tank. When the water level in the water tank drops to a first preset water level, a solenoid valve is opened to replenish water to the water tank, and when the water level rises to a second preset water level, the water replenishment stops. The pipeline drinking water device with the automatic water replenishment function mainly determines the water level in the water tank through an induction switch. If the induction switch fails, it may cause the water tank not to be replenished in time, or the water replenishment cannot be terminated in time when the water replenishment is in place. For the latter situation, a water leakage accident will occur.

[0048] Once a water leakage accident occurs in this pipeline drinking water device with the automatic water replenishment function, the consequences will be relatively serious and will cause relatively serious property losses. Therefore, it is necessary to consider the problem of water leakage protection.

[0049] Based on the above situation, the embodiment of the present utility model provides a pipeline drinking water device, aiming to reduce the risk of water leakage accidents.

[0050] As Figure 1 、 Figure 2 shown, the pipeline drinking water device 10 in the embodiment of the present utility model includes a water tank 100, a water inlet assembly 200, a solenoid valve 300, a balance water pipe 400, a water receiving box 500, and a water leakage detection assembly 600. The water inlet assembly 200 is connected to the water tank 100, and the water inlet assembly 200 is used to replenish water to the water tank 100. The solenoid valve 300 is arranged on the water inlet assembly 200. The bottom of the balance water pipe 400 is connected to the lower part of the water tank 100 through a connecting pipe, so that the balance water pipe 400 and the water tank 100 form a communicating vessel structure. An outlet 410 is arranged at the upper part of the balance water pipe 400. The water receiving box 500 is used to receive the water flowing out of the outlet 410. The water leakage detection assembly 600 is used to detect whether there is water in the water receiving box, and the water leakage detection assembly 600 is electrically connected to the solenoid valve 300. Among them, the water leakage detection assembly 600 can be configured to control the solenoid valve 300 to close when it detects that there is water in the water receiving box 500.

[0051] Specifically, the water tank 100 is a water storage structure of the pipeline drinking water device 10, and the water tank 100 has a certain volume. After the water purified by an external water purification device enters the pipeline drinking water device 10, it can be stored in the water tank 100. Generally speaking, the pipeline drinking water device 10 is internally provided with a heating component and a refrigerating component. The water in the water tank 100 can be heated by the heating component and provided to the user, or cooled by the refrigerating component and provided to the user. In this way, the user can obtain hot water or ice water. Of course, when neither the heating component nor the refrigerating component is started, the water in the water tank 100 can be directly provided to the user, and in this way, the user can obtain normal temperature water.

[0052] The water inlet assembly 200 is used to connect an external water supply pipeline. Exemplarily, the water supply pipeline can be connected to the water outlet end of a water purification device. In this way, the purified water processed by the water purification device can be supplied to the water tank 100. The solenoid valve 300 is arranged on the water inlet assembly 200. By controlling the state of the solenoid valve 300, the water tank 100 can be filled with water and the water filling can be stopped. Specifically, when the solenoid valve 300 is opened, the purified water will enter the water tank 100 to fill the water tank 100. When the solenoid valve 300 is closed, the water filling will stop.

[0053] The water receiving box 500 is a container capable of holding a certain volume of water. For example, the water receiving box 500 can be an open box body or a closed box body. It can be understood that if the water receiving box 500 adopts a closed box body, the water receiving box 500 needs to be provided with air vents to keep the air pressure inside and outside the water receiving box 500 balanced, so that the water flowing out through the water outlet 410 can enter the water receiving box 500.

[0054] In the pipeline drinking water device 10 of the embodiment of the present utility model, a balance water pipe 400 is provided. The bottom of the balance water pipe 400 is connected to the lower part of the water tank 100 through a connecting pipe, so that a communicating vessel structure is formed between the balance water pipe 400 and the water tank 100. According to the principle of the communicating vessel, the water in the balance water pipe 400 and the water in the water tank 100 have the same water level. In this way, during the process of filling the water tank 100, as the water level in the water tank 100 rises, the water level in the balance water pipe 400 also rises synchronously. When the water in the balance water pipe 400 rises to the position where the water outlet 410 is located, the water in the balance water pipe 400 will flow out through the water outlet 410 and enter the water receiving box 500. At this time, the water leakage detection component 600 will detect that there is water in the water receiving box 500. When the water leakage detection component 600 detects that there is water in the water receiving box 500, it will control the solenoid valve 300 to close. In this way, the water leakage problem caused by the failure to stop water filling in time after the water filling is in place can be avoided, so as to reduce the risk.

[0055] Further, the balance water pipe 400 can extend along the height direction H of the pipeline drinking water device 10. In this way, it is beneficial to reduce the overall length of the balance water pipe 400, thereby avoiding the balance water pipe 400 occupying extra space.

[0056] Exemplarily, the cross-sectional shape of the balance water pipe 400 can be circular, square, polygonal or other shapes, and the present utility model does not limit this. However, it can be understood that when the cross-sectional shape of the balance water pipe 400 is circular or square, the balance water pipe 400 is the easiest to process and form, which is beneficial to reducing the manufacturing cost.

[0057] In some embodiments, such as Figure 2 、 Figure 4As shown, the water leakage detection component 600 includes a detection circuit 620 and a probe 610 connected to the detection circuit 620. At least part of the probe 610 is located inside the water receiving box 500. Among them, the detection circuit 620 can be arranged on a circuit board. A part of the structure of the probe 610 extends into the water receiving box 500 or the whole probe 610 is located inside the water receiving box 500. When there is water in the water receiving box 500, the probe 610 will come into contact with the water, causing the detection circuit 620 to conduct with water as a conductor and generate an electrical signal. In this way, it is possible to detect whether there is water in the water receiving box 500.

[0058] Specifically, the probe can be a metal probe. For example, a copper probe, an aluminum probe, a silver probe, etc., so as to have good electrical conductivity.

[0059] Furthermore, the probe 610 contacts the bottom of the water receiving box 500. Thus, once the water flowing out through the water outlet 410 enters the water receiving box 500, it can be immediately contacted by the probe 610, so that the water leakage detection component 600 can immediately control the solenoid valve 300 on the water inlet component 200 to close, thereby improving the response speed of the solenoid valve 300 and further reducing the risk of water leakage accidents.

[0060] In one of the embodiments, as Figure 4 shown, the water leakage detection component 600 further includes a controller 630. The controller 630 is electrically connected to both the detection circuit 620 and the solenoid valve 300. Among them, the controller is configured to control the solenoid valve 300 to close when there is water in the water receiving box 500. When the probe 610 contacts the water, the detection circuit 620 will conduct with water as a conductor, thereby generating an electrical signal. When the controller 630 receives the above electrical signal, it will send a control signal to the control valve to control the solenoid valve 300 to close.

[0061] In some of the embodiments, the controller 630 can also be configured to control the solenoid valve 300 to close when the opening duration of the solenoid valve 300 reaches a preset duration. That is to say, when the solenoid valve 300 is opened to replenish water to the water tank 100, the controller 630 also continuously monitors the opening duration of the solenoid valve 300. When the opening duration of the solenoid valve 300 reaches the preset duration, the controller 630 will control the solenoid valve 300 to close. In this way, this embodiment adopts multiple protection means, thereby reducing the risk of water leakage accidents to an extremely low level. Exemplarily, the preset duration can be 180 seconds, 300 seconds, 420 seconds, etc., and can be specifically set according to actual needs.

[0062] In some embodiments, as Figure 2As shown in the figure, a first air pressure balance port 110 is provided at the top of the water tank 100, and a second air pressure balance port 420 is provided at the top of the balance water pipe 400. The first air pressure balance port 110 is connected to the second air pressure balance port 420 through a pipeline, or both the first air pressure balance port 110 and the second air pressure balance port 420 are communicated with the external atmosphere. In this way, the balance water pipe 400 and the water tank 100 are kept in air pressure balance, so that the water in the balance water pipe 400 and the water in the water tank 100 can maintain the same water level.

[0063] Further, along the height direction H of the pipeline drinking water device 10, the water outlet 410 is lower than the first air pressure balance port 110 and the second air pressure balance port 420. In other words, both the first air pressure balance port 110 and the second air pressure balance port 420 are arranged higher than the water outlet 410. Thus, it is possible to avoid the water in the water tank 100 flowing out through the first air pressure balance port 110 and causing a leakage accident.

[0064] In some embodiments, along the height direction H of the pipeline drinking water device 10, the top of the balance water pipe 400 and the top of the water tank 100 are at the same height position. If the top of the balance water pipe 400 is lower than the top of the water tank 100, and the height where the water outlet 410 is located is also lower than the height where the top of the balance water pipe 400 is located, in this way, there will be an obvious section of space (the part higher than the water outlet 410) in the upper part of the water tank 100 that cannot store water all the time, which will cause obvious waste of the space in the water tank 100. On the contrary, if the top of the balance water pipe 400 is higher than the top of the water tank 100, the part of the balance water pipe 400 higher than the water tank 100 will also cause waste. Therefore, in this embodiment, the top of the balance water pipe 400 and the top of the water tank 100 are set at the same height, so that waste can be reduced as much as possible.

[0065] In some embodiments, the cross-sectional area of the balance water pipe 400 is less than or equal to 1 / 3 of the cross-sectional area of the water tank 100. Since the balance water pipe 400 is mainly used to monitor the water level in the water tank 100, the size of the balance water pipe 400 does not need to be too large, so as to avoid the overall volume of the pipeline drinking water device 10 being too large due to the balance water pipe 400 occupying more space. In this embodiment, the cross-sectional area of the balance water pipe 400 can not exceed 1 / 3 of the cross-sectional area of the water tank 100. In this way, while ensuring that the balance water pipe 400 can more accurately reflect the water level in the water tank 100, the volume of the balance water pipe 400 can be relatively small.

[0066] In some embodiments, such as Figure 3As shown, a magnetic float 710 is provided inside the balance water pipe 400. The pipeline drinking water device 10 further includes a first induction switch 720 and a second induction switch 730. The first induction switch 720 is arranged at a first height position of the balance water pipe 400, and the second induction switch 730 is arranged at a second height position of the balance water pipe 400. Both the first induction switch 720 and the second induction switch 730 are electrically connected to the solenoid valve 300, and the first height position is lower than the second height position. Among them, the first induction switch 720 can be configured to control the solenoid valve 300 to open when the magnetic float 710 is sensed, and the second induction switch 730 can be configured to control the solenoid valve 300 to close when the magnetic float 710 is sensed.

[0067] Exemplarily, the first induction switch 720 and the second induction switch 730 are reed switch magnetic control switches. The magnetic float 710 can be a float with a magnetic material built-in. For example, the magnetic float 710 can include a floating block and a magnet arranged inside the floating block. Among them, the floating block can be made of a floating body material, such as foam plastic, foam glass, foam aluminum, wood, polyolefin materials, etc. The floating block is used to provide buoyancy, and the magnet is used to be sensed by the first induction switch 720 and the second induction switch 730. The magnetic float 710 can be spherical, ellipsoidal, cuboid, etc., or other irregular shapes.

[0068] In this embodiment, the first height position corresponds to the low level of the water tank 100, and the second height position corresponds to the high level of the water tank 100. The first induction switch 720 and the second induction switch 730 cooperate with the magnetic float 710 to realize the automatic water replenishment control process. Specifically, the magnetic float 710 will float up and down with the change of the water level in the balance water pipe 400. When the water level in the balance water pipe 400 drops to the first height position, the magnetic float 710 will also drop to the first height position. At this time, the first induction switch 720 will sense the magnetic float 710, thereby controlling the solenoid valve 300 on the water inlet assembly 200 to open. In this way, the purified water will enter the water tank 100 to replenish water for the water tank 100. With the water replenishment process, the water level in the balance water pipe 400 will rise. When the water level in the balance water pipe 400 rises to the second height position, the magnetic float 710 will also rise to the second height position. At this time, the second induction switch 730 will sense the magnetic float 710, thereby controlling the solenoid valve 300 on the water inlet assembly 200 to close and stop the water replenishment. By repeating this cycle, the pipeline drinking water device 10 can be equipped with the function of automatic water replenishment.

[0069] Further, along the height direction H of the pipeline drinking water device 10, the second induction switch 730 is arranged below the water outlet 410. With such an arrangement, on the one hand, the automatic water replenishment process of the water tank 100 will not be affected by the water outlet 410; on the other hand, during the water replenishment process, when the second induction switch 730 fails and cannot timely control the solenoid valve 300 to close, the water in the balance water pipe 400 will flow out through the water outlet 410 and enter the water receiving box 500. In this way, the water leakage detection component 600 will detect that there is water in the water receiving box 500 and control the solenoid valve 300 to close to avoid a water leakage accident.

[0070] In some other embodiments, the pipeline drinking water device 10 may also adopt other forms of water level detection means to detect the water level in the balance water pipe 400 and control the opening and closing of the solenoid valve 300. For example, an infrared detection component may be arranged at the top of the balance water pipe 400, and the emission direction of the infrared detection component is downward. Thus, the distance between the current liquid level and the infrared detection component can be detected through the infrared detection component. Correspondingly, the infrared detection component may be configured to control the solenoid valve 300 to open when the distance between the liquid level and the infrared detection component is equal to the first preset distance, and control the solenoid valve 300 to close when the distance between the liquid level and the infrared detection component is equal to the second preset distance. Among them, the first preset distance is greater than the second preset distance. The first preset distance may correspond to the low level of the balance water pipe 400, and the second preset distance may correspond to the high level of the balance water pipe 400. Thus, the function of automatically replenishing water for the pipeline drinking water device 10 can also be realized.

[0071] In some embodiments, as Figure 2 shown, the water receiving box 500 is located below the balance water pipe 400, and the pipeline drinking water device 10 further includes a drainage pipe 800. One end of the drainage pipe 800 is connected to the water outlet 410, and the other end of the drainage pipe 800 extends into the water receiving box 500. Thus, the water flowing out through the water outlet 410 will flow into the water receiving box 500 along the drainage pipe 800, which can prevent the water flowing out of the water outlet 410 from falling outside the water receiving box 500 and not being detected by the water leakage detection component 600.

[0072] Specifically, the drainage pipe 800 may be a flexible pipe, so that the shape of the drainage pipe 800 can be set more flexibly, and the drainage pipe 800 can more easily avoid other structures in the pipeline drinking water device 10.

[0073] Further, the water receiving box 500 is provided with a pipe joint 510. The other end of the drainage pipe 800 is sleeved on the pipe joint 510. The interior of the pipe joint 510 has a flow channel, and the flow channel is communicated with the interior of the water receiving box 500. With such a setting, the drainage pipe 800 and the water receiving box 500 can be stably connected, so that the water flowing out through the water outlet 410 can be guided into the water receiving box 500 by the drainage pipe 800.

[0074] In some embodiments, the water inlet assembly 200 includes a water inlet pipe 210 and a tee joint 220. The tee joint 220 has a first interface, a second interface and a third interface that are communicated with each other. The first interface is connected to the water tank 100, the second interface is connected to the connecting pipe, and the third interface is connected to the water inlet pipe 210 through the solenoid valve 300. Among them, the water inlet pipe 210 can be connected to an external water supply pipeline. The third interface of the tee joint 220 is connected to the water inlet pipe 210 through the solenoid valve 300, and the first interface is connected to the water tank 100. In this way, the solenoid valve 300 can control whether the external water can enter the water tank 100. When the solenoid valve 300 is opened, the external water enters the tee joint 220 through the third interface and then enters the water tank 100 through the first interface. In addition, the second interface of the tee joint 220 is connected to the connecting pipe. Thus, the balance water pipe 400 can be communicated with the water tank 100 through the connecting pipe, and further, the balance water pipe 400 and the water tank 100 form a communicating vessel structure.

[0075] In some of these embodiments, as Figure 1 , Figure 2 shown, the pipeline drinking water device 10 further includes a housing 900. The water tank 100 is detachably arranged in the housing 900. The balance water pipe 400, the water receiving box 500 and the water leakage detection assembly 600 are all arranged inside the housing 900. In this embodiment, the water tank 100 is detachably arranged in the housing 900. In this way, the water tank 100 can be conveniently cleaned regularly. In addition, the balance water pipe 400, the water receiving box 500, the water leakage detection assembly 600, etc. are all arranged inside the housing 900. That is to say, the balance water pipe 400 is always fixedly installed in the housing 900. When the water tank 100 is detached from the housing 900, the water tank 100 will be disconnected from the balance water pipe 400. When the water tank 100 is installed on the housing 900, the water tank 100 will be communicated with the balance water pipe 400 again through the connecting pipe to form a communicating vessel structure.

[0076] Further, a handle can be arranged on the water tank 100. In this way, after the water tank 100 is detached from the housing 900, it is convenient for the user to take and transfer the water tank 100.

[0077] In the description of the present utility model, it should be understood that if there are terms such as "upper", "lower", "left", "right", etc., the orientation or positional relationship indicated is based on the orientation or positional relationship shown in the drawings.
