[0002] With the development of technology, water purifiers have become indispensable in people's daily lives. Water purifiers can directly provide users with purified water and can also deliver purified water to a heating tank to provide users with heated purified water. However, current heating devices have the drawback of not being able to heat water above the boiling point. Utility Model Content

[0003] This application provides a water supply device and a water purifier. It solves the problem that existing heating devices cannot heat water above the boiling point. The technical solution is as follows: On the one hand, a water supply device is provided, which is installed inside a water purifier and is used to supply treated water to the outlet of the water purifier, including: a sealed heating inner tank and an electric heating element; The heating inner liner has an inlet pipe and an outlet pipe extending outwards. The portion of the outlet pipe extending outwards from the end of the heating inner liner faces the outlet. The heating inner liner has an annular side extending along its length. The heating inner liner has at least one reversible elastic portion distributed on the annular side. In the initial state, the reversible elastic portion is recessed towards the cavity of the heating inner liner. The heating section of the electric heating element is installed inside the heating tank to heat the water flowing into the heating tank through the water inlet pipe.

[0004] Optionally, the heating inner liner is a metal inner liner, and the thickness of the reversible elastic part is less than the thickness of the area of ​​the metal inner liner excluding the area where the reversible elastic part is provided.

[0005] Optionally, the resettable elastic part has two opposing arc surfaces, one arc surface of the resettable elastic part facing the cavity of the heating inner liner, and the other arc surface of the resettable elastic part located outside the cavity of the heating inner liner; wherein, at least one arc surface of the resettable elastic part has multiple spaced concave portions and protrusions.

[0006] Optionally, the heated inner liner has two resettable elastic portions distributed on the annular side, the two resettable elastic portions being disposed opposite to each other.

[0007] Optionally, the outer contour of the resettable elastic part is circular or elliptical.

[0008] Optionally, the water supply device includes: a first switch valve installed on the inlet pipe for controlling the on / off state of the inlet pipe, and a second switch valve installed on the outlet pipe for controlling the on / off state of the outlet pipe.

[0009] Optionally, the water supply device further includes: a one-way valve installed on the water inlet pipe, the one-way valve being installed between the first switch valve and the outlet of the water inlet pipe, and water flowing through the one-way valve into the heating inner tank.

[0010] Optionally, the water supply device includes a temperature detection component installed on the heating inner tank, the temperature detection component being used to detect the temperature of the water inside the heating inner tank.

[0011] Optionally, the water supply device includes a level gauge installed on the heating inner tank.

[0012] On the other hand, a water purifier is provided, the water purifier including: a faucet component and any of the above-mentioned water supply devices, the faucet component being provided with a water outlet, and the water outlet pipe in the water supply device cooperating with the faucet component; The faucet component has a water-out state and a water-out state.

[0013] The beneficial effects of the technical solutions provided in this application include at least the following: A sealed heating inner tank is installed in the water supply device. The inner tank has inlet and outlet pipes. A first switch valve on the inlet pipe allows room temperature water to be injected into the inner tank when open, and closes when the water level reaches a certain value. Additionally, the inner tank contains a heating section for an electric heating element, which heats the room temperature water inside when operating normally. During heating, the pressure in the sealed cavity slowly increases as the inner tank is filled with liquid. When the pressure exceeds a set threshold of the resettable elastic part, the elastic part deforms outward, increasing the sealed space, absorbing the increased pressure, reducing the pressure generated during heating, and lowering the tank's pressure resistance. By slowly increasing the internal cavity pressure, the boiling point of the water during heating is raised, achieving a temperature ≥100℃ or "boiling." When the internal temperature of the inner tank decreases, the pressure in the sealed space drops, and the resettable elastic part returns to its initial state. In other words, in a closed heating container system, the internal pressure of the inner tank is increased through the heating process, which correspondingly raises the saturation temperature (i.e., boiling point) of the water. This allows the water in the inner tank to be heated to a temperature of 100°C or higher, thus meeting the user's need for boiling water at that boiling point. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the present invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification do not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0020] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a water supply device provided in an embodiment of this application. The water supply device can be installed inside a water purifier and is used to supply treated water to the outlet of the water purifier. The water supply device may include: a sealed heating inner tank 100 and an electric heating element 200.

[0021] The heating inner tank 100 of the water supply device has an inlet pipe 101 and an outlet pipe 102 extending outwards. The portion of the outlet pipe 102 extending outwards from the end of the heating inner tank 100 faces the water outlet of the water purifier. The heating inner tank 100 may have an annular side portion C1 extending along its length, and at least one resettable elastic portion T1 distributed at the annular side portion C1. In the initial state, the resettable elastic portion T1 is recessed towards the cavity of the heating inner tank 100. For example, the outline shape of the resettable elastic portion T1 may be circular or elliptical. Here, the heating inner tank 100 may include a top D1 and a bottom D2 disposed opposite each other, and an annular side portion C1 located between the top D1 and the bottom D2. The inlet pipe 101 and the outlet pipe 102 may extend from the top D1 of the heating inner tank 100. It should be noted that the rigidity of the other parts of the heating inner tank 100, except for the resettable elastic portion T1, is relatively high.

[0022] The heating section of the electric heating tube 200 in the water supply device is installed inside the heating inner tank 100 and can be used to heat the water flowing into the heating inner tank 100 from the water inlet pipe 101.

[0023] Here, the water supply device also includes: a first switching valve 300 installed on the inlet pipe 101 to control the on / off state of the inlet pipe 101, and a second switching valve 400 installed on the outlet pipe 102 to control the on / off state of the outlet pipe 102. Thus, the first switching valve 300 and the second switching valve 400 can control the on / off state of the inlet pipe 101 and the outlet pipe 102 respectively. For example, when both the first switching valve 300 and the second switching valve 400 are closed, the heating inner tank 100 can be sealed off.

[0024] In this embodiment, a sealed heating inner tank 100 is provided in the water supply device. The heating inner tank 100 has an inlet pipe 101 and an outlet pipe 102 extending outwards. A first switch valve 300 provided on the inlet pipe 101 can inject room temperature water into the heating inner tank 100 when it is open. After the water level in the heating inner tank 100 reaches a certain value, the first switch valve 300 is closed. In addition, a heating section of an electric heating tube 200 is provided inside the heating inner tank 100. Thus, when the electric heating tube 200 is in normal working condition, it can heat the room temperature water in the sealed heating inner tank 100. Here, when the heating inner tank 100 is filled with liquid and is heated, the pressure in the closed cavity space will slowly increase. The interior is continuously heated. When the pressure exceeds the set threshold of the resettable elastic part T1, the resettable elastic part T1 begins to deform outwards, increasing the internal sealed space, absorbing the increased pressure value, reducing the pressure generated during the heating process of the tank, and reducing the pressure-bearing strength of the tank. By slowly increasing the internal cavity pressure, the boiling point temperature of water during the internal heating process is raised, achieving an effect of ≥100℃ or "boiling". When the internal temperature of the heating inner tank 100 decreases, the pressure in the sealed space begins to drop, and the resettable elastic part T1 returns to its initial state as the pressure decreases. In other words, in a sealed heating container system, by increasing the internal pressure of the heating inner tank 100 during the heating process, the saturation temperature (i.e., boiling point) of the water is correspondingly raised, thereby enabling the water inside the heating inner tank 100 to be heated to degrees Celsius or higher, meeting the user's need for boiling water at that boiling point. After the water in the heating inner tank 100 is heated to boiling, the user can control the second switch valve 400 to open the water outlet pipe 102 to use the boiling water.

[0025] In summary, this application provides a water supply device, which may include a sealed heating inner tank and an electric heating element. By providing a sealed heating inner tank with an inlet and an outlet pipe, a first switch valve on the inlet pipe allows room temperature water to be injected into the heating inner tank when open, and closes when the water level reaches a certain value. Additionally, the heating inner tank includes a heating section for the electric heating element, enabling the room temperature water inside the sealed heating inner tank to be heated when the electric heating element is in normal working condition. Here, when the heating inner tank is filled with liquid and heated, the pressure in the closed cavity slowly increases, and the internal heating continues. When the pressure exceeds a set threshold of the resettable elastic part, the resettable elastic part begins to deform outward, increasing the internal sealed space, absorbing the increased pressure, reducing the pressure generated during the heating process, and lowering the pressure-bearing capacity of the tank. By slowly increasing the internal cavity pressure, the boiling point temperature of water during the internal heating process is raised, achieving an effect of ≥100℃ or "boiling." When the internal temperature of the heating tank decreases, the pressure in the sealed space begins to drop, and the reversible elastic part returns to its initial state as the pressure decreases. In other words, in a sealed heating container system, the internal pressure of the tank is increased during the heating process, correspondingly raising the saturation temperature (i.e., boiling point) of the water. This allows the water inside the heating tank to be heated to degrees Celsius or higher, meeting the user's need for boiling water at that boiling point.

[0026] Optionally, the heating inner tank 100 in the water supply device can be a metal inner tank, and the thickness of the resettable elastic part T1 can be less than the thickness of the area of ​​the metal inner tank 100 excluding the area where the resettable elastic part T1 is located. This ensures that the resettable elastic part T1 has a certain elastic deformation capacity. When the pressure inside the cavity of the heating inner tank 100 exceeds a set threshold of the resettable elastic part T1, the resettable elastic part T1 begins to deform outward, increasing the internal sealed space, absorbing the increased pressure value, reducing the pressure generated during the tank heating process, and lowering the pressure-bearing strength of the tank. It should be noted that the resettable elastic part T1 and the heating inner tank 100 can be an integrally formed structure, and the material of the heating inner tank 100 can be 304 or 316 stainless steel.

[0027] Please refer to the following in this application: Figure 2 , Figure 2This is a schematic diagram of another water supply device provided in an embodiment of this application. The resettable elastic portion T1 may have two opposing arc surfaces m. One arc surface m of the resettable elastic portion T1 faces the cavity of the heating inner tank 100, while the other arc surface m of the resettable elastic portion T1 is located outside the cavity of the heating inner tank 100 and away from the cavity of the heating inner tank 100. At least one arc surface m of the resettable elastic portion T1 has multiple spaced-apart concave portions and protrusions (not shown in the figure). Thus, by having multiple spaced-apart concave portions and protrusions on at least one arc surface m of the resettable elastic portion T1, the ductility of the resettable elastic portion T1 can be effectively increased.

[0028] For example, the heating liner 100 may have two resettable elastic portions T1 distributed on the annular side, which may be arranged opposite to each other.

[0029] In the embodiments of this application, such as Figure 2 As shown, the water supply device also includes a one-way valve 500 installed on the water inlet pipe 101. The one-way valve 500 is installed between the first switch valve 300 and the outlet of the water inlet pipe 101, and the water flows through the one-way valve 500 into the heating inner tank 100. In this way, the one-way valve 500 installed before the water inlet of the heating inner tank 100 can effectively prevent the hot water from flowing back into the water.

[0030] Optional, such as Figure 2 As shown, the water supply device may include a temperature detection component 600 installed on the heating inner tank 100, which is used to detect the temperature of the water inside the heating inner tank 100. Thus, the temperature detection component 600 can detect the temperature of the water inside the heating inner tank 100 in real time, allowing the user to know the water temperature in real time. For example, the temperature detection component 600 may include a thermometer or a temperature sensor.

[0031] In the embodiments of this application, such as Figure 2 As shown, the water supply device may include a level gauge 700 installed on the heating inner tank 100. This allows the user to monitor the water level in the heating inner tank 100 in real time via the level gauge 700, ensuring timely replenishment of water to the heating inner tank 100.

[0032] Optional, such as Figure 1 As shown, the heating inner tank may have a baffle plate 103 installed at the outlet of the water inlet pipe 101, which may be arranged opposite to the outlet of the water inlet pipe 101. In this way, the baffle plate 103 disperses the room temperature water entering the heating inner tank 100 from the water inlet pipe 101, reducing the impact on the temperature of the already heated water.

[0033] In summary, this application provides a water supply device, which may include a sealed heating inner tank and an electric heating element. By providing a sealed heating inner tank with an inlet and an outlet pipe, a first switch valve on the inlet pipe allows room temperature water to be injected into the heating inner tank when open, and closes when the water level reaches a certain value. Additionally, the heating inner tank includes a heating section for the electric heating element, enabling the room temperature water inside the sealed heating inner tank to be heated when the electric heating element is in normal working condition. Here, when the heating inner tank is filled with liquid and heated, the pressure in the closed cavity slowly increases, and the internal heating continues. When the pressure exceeds a set threshold of the resettable elastic part, the resettable elastic part begins to deform outward, increasing the internal sealed space, absorbing the increased pressure, reducing the pressure generated during the heating process, and lowering the pressure-bearing capacity of the tank. By slowly increasing the internal cavity pressure, the boiling point temperature of water during the internal heating process is raised, achieving an effect of ≥100℃ or "boiling." When the internal temperature of the heating tank decreases, the pressure in the sealed space begins to drop, and the reversible elastic part returns to its initial state as the pressure decreases. In other words, in a sealed heating container system, the internal pressure of the tank is increased during the heating process, correspondingly raising the saturation temperature (i.e., boiling point) of the water. This allows the water inside the heating tank to be heated to degrees Celsius or higher, meeting the user's need for boiling water at that boiling point.

[0034] This application embodiment also provides a water purifier, which may include: a faucet component (not shown in the figure) and a water supply device. The faucet component is provided with a water outlet, and the water outlet pipe in the water supply device cooperates with the faucet component. The faucet component has a water outlet state and a non-water outlet state. The water supply device can be any of the above-mentioned water supply devices.

[0035] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0036] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
