Description

Technical Field

[0001] The present application relates to the technical field of drinking water equipment, and in particular to a water replenishing device and a water dispenser. Background Art

[0002] With the acceleration of urbanization and rising living standards, traditional drinking water methods are no longer able to meet the demand for immediate and hygienic drinking water. Technological advances in water dispensers, particularly in water treatment and intelligent control, have enabled them to quickly provide drinking water that meets drinking standards, satisfying the modern consumer's demand for convenient drinking water. Furthermore, water dispensers respond to public health needs, reducing the risk of water contamination, and have become a common fixture in homes, offices, and public spaces.

[0003] When a water dispenser is in use, the water tank needs to be refilled to meet people's drinking water needs. Typically, a water dispenser includes a raw water tank, which is used to store raw water that needs to be treated. In addition, some water dispensers also include a clean water tank, which is used to store purified water. However, when refilling the raw water tank of a water dispenser, the raw water tank is often disassembled and taken to the water source for refilling, and the refilling process is cumbersome and complicated. When refilling the clean water tank of a water dispenser, it is necessary to wait for the preparation of clean water, and it is difficult to directly add clean water to the clean water tank. The water refilling efficiency is low, the convenience of drinking water is poor, and it affects the user experience. Utility Model Content

[0006] The water replenishment device detects the water level in the water tank through a water level detector and switches the solenoid valve between the water inlet and the water outlet according to the water level. Specifically, when the water level in the water tank is lower than a preset water level, the solenoid valve is in a conducting state. At this time, the water inlet and the water outlet of the solenoid valve are connected, and the water inlet is connected to the water outlet, allowing external water to enter the water tank through the solenoid valve to replenish the water tank. When the water level in the water tank is higher than or equal to the preset water level, the solenoid valve is in a cut-off state, blocking the connection between the water inlet and the water outlet, thereby blocking the external water source from entering the water tank and stopping the replenishment of the water tank. This water replenishment device allows the water tank of the water dispenser to be replenished in a timely and effective manner without having to disassemble the water tank or wait for the preparation of purified water, thereby improving the water replenishment efficiency, thereby increasing the drinking convenience of the user and improving the user experience.

[0029] See Figures 1 to 4 In some embodiments, the water dispenser 1000 includes a water replenishing device 100 and a water tank 200. A water storage space 210 is formed in the water tank 200, and the water replenishing device 100 is mounted above the water tank 200 for replenishing the water storage space 210 with water.

[0030] The water replenishing device 100 includes a housing 10, a solenoid valve 20, and a water level detector 30. The top of the water tank 200 is open to facilitate water replenishment into the water tank 200. The housing 10 is mounted on the top of the water tank 200. Preferably, the shape and size of the housing 10 are configured to the shape and size of the water tank 200, so that the housing 10 can cover the opening of the water storage space 210, so that the housing 10 and the water tank 200 can form a closed water storage space 210, so as to prevent external impurities such as dust from affecting the water quality of the water in the water storage space 210, thereby improving the safety of the water and allowing users to use the water provided by the water dispenser 1000 with confidence.

[0031] Optionally, the side of the shell 10 facing the water tank 200 is configured to be stepped, and part of the shell 10 can be accommodated in the water storage space 210 of the water tank 200, that is, the size of the outer wall of part of the shell 10 is not larger than the size of the inner wall of the water tank 200 and the size of the outer wall of part of the shell 10 is larger than the size of the inner wall of the water tank 200, thereby forming a step on the shell 10, and the stepped shell 10 is placed on the top of the water tank 200.

[0032] The bottom surface of the stepped shell 10 can stably contact the top surface of the water tank 200, so that the water tank 200 can provide firm support for the shell 10, making the shell 10 more stable when placed on the top of the water tank 200, and the stepped setting can prevent the shell 10 from moving relative to the water tank 200, effectively maintaining the stability of the water replenishment device 100.

[0033] When installing the water replenishing device 100, the stepped shell 10 can be placed on the top of the water tank 200, which improves the convenience of use and installation of the water replenishing device 100. At the same time, the stepped design helps to enhance the sealing effect between the shell 10 and the water tank 200, preventing water from leaking from the connection between the shell 10 and the water tank 200.

[0034] The housing 10 defines a receiving space 13, within which the solenoid valve 20 is disposed. The housing 10 supports and protects the solenoid valve 20. The housing 10 also includes a water inlet 111 and a water outlet 121. The water inlet 111 is used to connect to an external water source, and the water inlet end 21 of the solenoid valve 20 is mounted to the water inlet 111. The water outlet 121 is used to connect to the water storage space 210 of the water tank 200, and the water outlet end of the solenoid valve 20 is mounted to the water outlet 121. The provision of the water inlet 111 facilitates connection between the solenoid valve 20 and an external water source, while the provision of the water outlet 121 facilitates communication between the solenoid valve 20 and the water storage space 210, thereby enabling stable delivery of external water to the water storage space 210.

[0035] The water level detector 30 can detect the water level in the water storage space 210 and, based on the water level, can cause the solenoid valve 20 to switch the connection between the water inlet 111 and the water outlet 121. The water level detector 30 is mounted on the housing 10, so that the water level detector 30 can remain stable during detection, thereby improving the reliability of the detection of the water level detector 30.

[0036] Alternatively, the water level detection component 30 may be communicatively connected to the solenoid valve 20, and the water level detection component 30 may directly feed back the water level to the solenoid valve 20 to control the on / off state of the solenoid valve 20, or the water level detection component 30 may feed back the water level to a control component such as a circuit board to control the on / off state of the solenoid valve 20 through the control component.

[0037] The solenoid valve 20 has an on state and a off state. When the water level in the water storage space 210 is lower than a preset water level, the solenoid valve 20 is in the on state, allowing external water to enter the water storage space 210. When the water level in the water storage space 210 is higher than or equal to the preset water level, the solenoid valve 20 is in the off state, preventing external water from entering the water storage space 210. Optionally, the preset water level is a position at which the water level detection member 30 can detect the water level in the water tank 200.

[0038] In other optional embodiments, the preset water level may include an extreme low water level and an extreme high water level. When the water level in the water storage space 210 is below the extreme low water level, the solenoid valve 20 is turned on, and the external water source replenishes water into the water storage space 210. When the water level in the water storage space 210 is above the extreme high water level, the solenoid valve 20 is cut off, and the external water source no longer replenishes water into the water storage space 210, so that the water tank 200 can be automatically replenished with water in a timely and effective manner at the extreme low water level, and the water tank 200 will no longer be replenished with water after reaching the extreme high water level, so as to prevent the water in the water storage space 210 from overflowing from the water tank 200, thereby improving the reliability of the water replenishing device 100.

[0039] Optionally, the water level detection member 30 is a water level sensor, and the water level sensor can be a probe liquid level sensor, a float liquid level sensor, an optical liquid level sensor, an ultrasonic liquid level sensor, etc.

[0040] The water level in the water storage space 210 of the water tank 200 is detected by the water level detection component 30 and the solenoid valve 20 is switched between the on state and the off state according to the water level, thereby controlling the conduction or blocking of the external water source and the water storage space 210 through the solenoid valve 20, so that the water replenishing device 100 can replenish the water tank 200 in a timely and effective manner, without the need to disassemble the water tank 200 or wait for the preparation of purified water, thereby improving the water replenishment efficiency, thereby improving the user's drinking convenience, and improving the user's usage experience.

[0041] Furthermore, the solenoid valve 20 is accommodated in the shell 10, and the water level detection component 30 is installed on the shell 10, so that the water level detection component 30, the solenoid valve 20 and the shell 10 can be integrated into a separate water replenishing device 100, so that the shape and size of the shell 10 can be adjusted according to the size and shape of the water tank 200, so that the water replenishing device 100 can be placed on different water tanks 200, so that the water replenishing device 100 is suitable for different water tanks 200 and has good applicability.

[0042] In an optional embodiment, the water tank 200 is a raw water tank, and the water replenishing device 100 can be configured above the raw water tank to replenish raw water in the raw water tank. At this time, the external water source is a raw water source, such as tap water, bottled water and other unpurified raw water sources.

[0043] Optionally, the water tank 200 is a clean water tank, and the water replenishing device 100 can also be configured above the clean water tank to replenish clean water for the clean water tank. At this time, the external water source is a clean water source, such as pure water treated by an RO machine or other purified clean water sources.

[0044] In some embodiments, the shell 10 includes a first shell 11 and a second shell 12, the first shell 11 is connected to the second shell 12 and the first shell 11 and the second shell 12 together form a accommodating space 13, the second shell 12 is mounted on the top of the water tank 200, the solenoid valve 20 is arranged between the first shell 11 and the second shell 12, and the water level detection component 30 is installed on the second shell 12.

[0045] The solenoid valve 20 is set in the accommodating space 13, so that the solenoid valve 20 can be isolated from the liquid storage space 210, avoiding direct contact between the electrical components of the solenoid valve 20 and water, so that the accommodating space 13 can provide an insulated operating environment for the solenoid valve 20, maintain the performance stability of the solenoid valve 20, and extend the service life of the solenoid valve 20.

[0046] Optionally, the first housing 11 is detachably connected to the second housing 12, thereby facilitating installation and removal of the solenoid valve 20. In other embodiments, the first housing 11 may also be fixedly connected to the second housing 12 by welding or the like.

[0047] Optionally, the water level detecting member 30 is detachably connected to the second housing 12, thereby facilitating installation and removal of the water level detecting member 30. In other embodiments, the water level detecting member 30 may also be fixedly connected to the second housing 12 by welding or the like.

[0048] Typically, detachable connections include, but are not limited to, threaded connections, screw connections, snap-fit connections, clamp connections, flange connections, pin-fit connections, and socket connections.

[0049] Optionally, the second shell 12 is mounted on the top of the water tank 200 to facilitate the installation and disassembly of the water replenishing device 100. At the same time, in the event of a power outage, the water storage space 210 can be manually replenished by disassembling the water replenishing device 100, thereby improving the ease of use of the water dispenser 1000.

[0050] Specifically in this embodiment, the second shell 12 includes a shell body 122, the side of the shell body 122 facing away from the water storage space 210 is connected to the first shell 11, and the side of the shell body 122 facing the water storage space 210 is connected to the water tank 200 and is installed with a water level detection component 30 and a water outlet 121, so as to facilitate the water level detection component 30 to detect the water level of the water tank 200 and facilitate the replenishment of water into the water tank 200.

[0051] In a feasible embodiment, the second housing 12 further includes a plug-in portion 123 connected to the housing body 122. The plug-in portion 123 is disposed within the accommodating space 13. One end of the plug-in portion 123 is connected to the water outlet 121, and the other end of the plug-in portion 123 is plugged into the water outlet 22. The provision of the plug-in portion 123 facilitates the connection between the solenoid valve 20 and the second housing 12. Furthermore, the provision of the plug-in portion 123 ensures that external water can stably enter the water storage space 210 through the water outlet 121.

[0052] Specifically, the plug-in portion 123 is a hollow structure, and the shape and size of the plug-in portion 123 are adapted to the shape and size of the water outlet end 22, thereby helping to ensure the connection stability and sealing between the plug-in portion 123 and the water outlet end 22, and preventing water from leaking into the accommodating space 13, so as to keep the accommodating space 13 dry, thereby ensuring the operating safety and reliability of the solenoid valve 20.

[0053] Optionally, the plug-in portion 123 is extended from the water outlet 121 in a direction away from the water storage space 210, so that the plug-in portion 123 can provide an installation position for the water outlet end 22 of the solenoid valve 20 to facilitate the installation of the solenoid valve 20, and the plug-in portion 123 can prevent the solenoid valve 20 from moving in the accommodating space 13, thereby improving the stability of the solenoid valve 20.

[0054] In this embodiment, the water inlet 111 is provided on the top surface of the first housing 11. The water outlet 22 of the solenoid valve 20 is plugged into the plug-in portion 123, and the water inlet 21 of the solenoid valve 20 abuts against the water inlet 111. The shape and size of the water inlet 111 match those of the water inlet 21. Thus, the water inlet 111 and the plug-in portion 123 provide a stable mounting position for the solenoid valve 20, thereby ensuring that the solenoid valve 20 is stably installed in the accommodating space 13. In this case, an external water source can be directly connected to the water inlet 21 of the solenoid valve 20. This approach is compact and fully utilizes the accommodating space 13 of the housing 10. In other embodiments, the water inlet 111 can also be provided on the side of the first housing 11 or the side of the second housing 12.

[0055] In other embodiments not shown, a corresponding plug-in portion may also be provided on the first housing 11, with one end of the plug-in portion connected to the water inlet 111 and the other end connected to the water inlet end 21 of the solenoid valve 20. In this case, an external water source can be connected to the water inlet 111, and water is delivered to the water inlet end 21 of the solenoid valve 20 through the plug-in portion. The solenoid valve 20 is fixedly installed in the accommodating space 13 by the plug-in portion of the first housing 11 and the plug-in portion 123 of the second housing 12.

[0056] In some embodiments, see Figures 2 to 4 The second shell 12 also includes a accommodating portion 124, which is extended from the shell body 122 in a direction away from the plug-in portion 123. The accommodating portion 124 forms an installation space 14 for accommodating the water level detection component 30, so that the accommodating portion 124 can protect the water level detection component 30 and avoid damage to the water level detection component 30, and the accommodating portion 124 can be accommodated in the water storage space 210, so that the water level detection component 30 located in the installation space 14 can detect the water level of the water storage space 210.

[0057] Optionally, an exhaust hole 1241 is provided on the second shell 12 for exhausting the air in the accommodating portion 124 so that the water in the water storage space 210 can stably enter the installation space 14 , so that the water level detection component 30 can detect the water level in the water tank 200 .

[0058] Specifically, in this embodiment, the accommodating portion 124 is provided with an exhaust hole 1241. The installation space 14 can be connected to the water storage space 210 through the exhaust hole 1241, and connected to the external environment through the water storage space. Therefore, when water in the water storage space 210 enters the installation space 14, the air in the installation space 14 can be discharged through the exhaust hole 1241, so that the air pressure in the installation space 14 and the water storage space 210 is consistent. In addition, the water can continue to rise in the installation space 14, making the water replenishment process smooth and reliable. It should be noted that the shape, size, and number of the exhaust holes 1241 are not limited as long as the air pressure in the installation space 14 and the water storage space 210 can be balanced.

[0059] In other embodiments, the exhaust hole 1241 may also be provided on the shell body 122 , so that the installation space 14 is connected to the accommodating space 13 through the exhaust hole 1241 , and is connected to the external environment through the accommodating space 13 to exhaust the air in the installation space 14 .

[0060] Furthermore, the water outlet 121 is located outside the accommodating portion 124, and the water level detection component 30 is located inside the accommodating portion 124, so that when the external water source is replenished, the water flowing into the liquid storage space 210 through the water outlet 121 will be blocked by the accommodating portion 124, avoiding direct contact between the water and the water level detection component 30, thereby ensuring the accuracy of the water level detected by the water level detection component 30.

[0061] In a feasible embodiment, the second housing 12 further includes a guide portion 125, one end of which is connected to the water outlet 121, and the other end of which extends toward the water storage space 210. The provision of the guide portion 125 allows water passing through the water outlet 121 to stably flow into the water storage space 210, thereby ensuring the stability of the water flow.

[0062] Specifically, the guide part 125 is a hollow structure. When the water level in the water storage space 210 is lower than the preset water level, the solenoid valve 20 is turned on, and the external water source replenishes water into the water storage space 210. The water from the external water source enters the water storage space 210 through the solenoid valve 20, the plug-in part 123, the water outlet 121 and the guide part 125 in sequence.

[0063] In this embodiment, the guide portion 125 is connected to the accommodating portion 124 and is arranged outside the accommodating portion 124. The extension length of the guide portion 125 is smaller than the extension length of the accommodating portion 124, so that the water in the guide portion 125 can both stably enter the water storage space 210 and avoid the water in the guide portion 125 from entering the installation space 14, thereby ensuring the detection accuracy of the water level detection component 30.

[0064] Preferably, the guide portion 125 and the water outlet 121 are arranged as close as possible to the central axis of the second shell 12, so as to help the water replenished by the external water source flow into the water storage space 210 evenly and stably, thereby improving the uniformity and smoothness of water replenishment.

[0065] The housing 122, the plug-in portion 123, the receiving portion 124, and the flow guide 125 are preferably integrally formed, tightly integrating the housing 122, the plug-in portion 123, the receiving portion 124, and the flow guide 125. This enhances the overall strength and stability of the second housing 12 and reduces the gaps and interfaces between the housing 122, the plug-in portion 123, the receiving portion 124, and the flow guide 125, thereby achieving a better sealing effect, effectively preventing water leakage, and ensuring the safety and stability of the water dispenser 1000. In other embodiments, the plug-in portion 123, the receiving portion 124, and the flow guide 125 may also be provided separately.

[0066] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above embodiments merely illustrate several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
