Description

Technical Field

[0001] This application relates to the field of faucet technology, specifically to a faucet. Background Technology

[0002] Instantaneous water heaters, also known as fast-heating electric water heaters or simply electric water heaters, have a built-in heating element that provides hot water within 3-5 seconds of being turned on, making them popular with consumers. However, in areas with high altitudes and low air pressure, the boiling point of water decreases. In these areas, the maximum temperature the heating element can reach when heating water is typically 95℃, meaning the water isn't truly boiled. Furthermore, because there's a water pipe between the heating element and the outlet, some heat is lost as the hot water flows through it, causing the temperature to drop. Consequently, the hot water received by the user is often below 90℃, failing to meet the user's need for hot water. Utility Model Content

[0003] This application provides a faucet to solve the technical problems of instant faucets used in areas with high altitude and low air pressure having difficulty boiling water and producing low amounts of hot water.

[0004] The technical solution adopted in this application is as follows:

[0005] A faucet includes a housing, an instant heating element, and a water vapor separation box. The water vapor separation box has a water outlet chamber and a hot water inlet, a drain outlet, and a vent outlet respectively connected to the water outlet chamber. The water outlet of the instant heating element is connected to the hot water inlet. The faucet also includes a pressure boosting component, a pressure relief component, and a water circuit adapter. The pressure boosting component is disposed on the fluid path downstream of the instant heating element to increase the pressure inside the instant heating element. The pressure relief component and the instant heating element are respectively connected to the water circuit adapter, and the pressure relief component is used to limit the pressure inside the instant heating element to below a preset value.

[0006] The faucet in this application also has the following additional technical features:

[0007] The pressure relief assembly is connected to the fluid path upstream of the instantaneous heat source and forms a parallel water channel structure with the instantaneous heat source.

[0008] It also includes a water inlet pipe for supplying water to the instantaneous heating element, the water adapter is a three-way connector, and the water inlet pipe, the water inlet of the instantaneous heating element and the pressure relief assembly are respectively connected to the three interfaces of the water adapter.

[0009] The pressure relief assembly is connected to the fluid path downstream of the instantaneous heat source, forming a series water circuit structure with the instantaneous heat source, and a parallel water circuit structure with the water vapor separator.

[0010] The outlet of the instant heating element is connected to the hot water inlet through the first water pipe and to the pressure relief component through the second water pipe. The water circuit adapter is a three-way connector. The outlet of the instant heating element, the first water pipe, and the second water pipe are respectively connected to the three interfaces of the water circuit adapter.

[0011] The pressure relief assembly includes a first external sleeve and a first one-way valve. The first external sleeve has a first inlet port and a first outlet port at its two ends, and the first one-way valve is installed inside the first external sleeve.

[0012] The first one-way valve includes a valve body and a valve core. The valve core is movably disposed within the valve body and has a water-blocking position that cuts off the connection between the first water inlet port and the first water outlet port, and a conducting position that connects the first water inlet port and the first water outlet port. When the valve core moves from the water-blocking position to the conducting position, it is confined to the conducting position by the valve body, thereby keeping the first water inlet port and the first water outlet port in a connected state.

[0013] The pressurization component is configured as a second one-way valve located inside the hot water inlet.

[0014] One end of the pressurization component is connected to the outlet of the instantaneous heating element, and the other end is connected to the water vapor separator.

[0015] The pressurization assembly includes a second external sleeve and a third one-way valve. The two ends of the second external sleeve are respectively provided with a second inlet port and a second outlet port. The second inlet port is connected to the outlet of the instantaneous heating element, and the second outlet port is connected to the hot water inlet. The third one-way valve is installed inside the second external sleeve. Alternatively, the pressurization assembly includes at least one valve body. The valve body has a third inlet port, a third outlet port, and a Tesla valve channel that reversely connects the third inlet port to the third outlet port. The third inlet port is connected to the outlet of the instantaneous heating element, and the third outlet port is connected to the hot water inlet.

[0016] Due to the adoption of the above technical solution, the technical effects achieved by this application are as follows:

[0017] 1. The faucet provided in this application has a pressurizing component installed in the fluid path downstream of the instant heating element. This pressurizing component increases the water flow pressure upstream of the instant heating element by resisting the water flow, thus making the pressure in the instant heating element higher than atmospheric pressure. Consequently, the boiling point of the water in the instant heating element is also higher than the boiling point at atmospheric pressure, and the boiling point of water increases with increasing pressure. Therefore, the instant heating element can heat water to a temperature of not less than 100°C to truly boil the water. Furthermore, even if some heat is lost during the flow of boiling water towards the water vapor separator, the water temperature will be reduced before the water reaches a boil. The water temperature is maintained above 95℃ when the water reaches the water-vapor separator, meeting the user's need for hot water. In addition, when the pressurization component malfunctions and completely blocks the water path from the instant heating element to the water-vapor separator, the pressure relief component can limit the pressure inside the instant heating element to below a preset value, playing a water path protection role and preventing the instant heating element from expanding, bursting, or even being damaged due to pressure buildup, thus improving the safety of the faucet. The water path adapter facilitates the connection and communication between the pressure relief component and the instant heating element, allowing the pressure relief component to release pressure from the instant heating element through the water path adapter.

[0018] 2. As a preferred embodiment of this application, the pressure relief component is connected to the fluid path upstream of the instantaneous heat source and forms a parallel water circuit structure with the instantaneous heat source. When the pressurization component completely blocks the water path from the instantaneous heat source to the water vapor separator due to a malfunction, causing the water pressure inside the instantaneous heat source to continuously increase, the pressure relief component discharges the water transported upstream of the instantaneous heat source towards the instantaneous heat source, so that the instantaneous heat source no longer receives water and the pressure is limited to below a preset value.

[0019] 3. As a preferred embodiment of this application, the water inlet pipe, the water inlet of the instantaneous heating element, and the pressure relief component are respectively connected to the three interfaces of the water circuit adapter. Water can be introduced into the instantaneous heating element through the water inlet pipe and the water circuit adapter. When depressurizing, the instantaneous heating element no longer receives water. The water in the water inlet pipe flows to the pressure relief component through the water circuit adapter and is discharged through the pressure relief component to achieve pressure relief. The water circuit structure is simple, easy to install, and has a low cost.

[0020] 4. As a preferred embodiment of this application, the pressure relief component is connected to the fluid path downstream of the instantaneous heating element to form a series water circuit structure with the instantaneous heating element and a parallel water circuit structure with the water vapor separator. When the faucet normally discharges hot water, the hot water output from the instantaneous heating element enters the water vapor separator through the pressurization component and is discharged from the drain of the water vapor separator. At this time, the pressure relief component is in a cut-off state, and the hot water output from the instantaneous heating element cannot be discharged through the pressure relief component. However, when the pressurization component completely blocks the water circuit from the instantaneous heating element to the water vapor separator due to a malfunction, the pressure inside the instantaneous heating element gradually rises, causing the pressure relief component to be open, thereby relieving pressure through the pressure relief component.

[0021] 5. As a preferred embodiment of this application, the pressure relief assembly includes a first external sleeve and a first one-way valve. The first external sleeve facilitates the connection of the pressure relief assembly to its upstream and downstream water circuit structures. When the first one-way valve is open, it connects the first inlet port and the first outlet port, allowing the instantaneous heating element to release pressure through the pressure relief assembly. When the first one-way valve is not open, it disconnects the first inlet port and the first outlet port. A connecting pipe is connected to the first inlet port and / or the first outlet port, facilitating the connection of the pressure relief assembly to other water circuit components via the connecting pipe.

[0022] 6. As a preferred embodiment of this application, when the valve core moves from the water-blocking position to the conducting position, it is constrained by the valve shell to the conducting position, thereby keeping the first water inlet port and the first water outlet port connected. In other words, after the pressure relief component moves from the water-blocking position to the conducting position, it cannot be reset from the conducting position to the water-blocking position. That is, the pressure relief component is a non-self-resetting structure. After the pressure relief component is turned on, it is in a normally open state, which allows the pressure in the instantaneous heating body to quickly return to normal pressure, effectively ensuring the safety of the entire system.

[0035] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0036] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0039] In this application, unless otherwise expressly specified and limited, the "above" or "below" of the second feature can mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. In the description of this specification, references to terms such as "an embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described can be combined in any suitable manner in one or more embodiments or examples.

[0040] In the embodiments of this application, a faucet is provided. For ease of explanation and understanding, the following content provided in this application is based on the illustrated product structure. Of course, those skilled in the art will understand that the above structure is only a specific example and illustrative illustration, and does not constitute a specific limitation on the technical solution provided in this application.

[0041] Reference Figures 1 to 9 As shown, the faucet provided in this application includes a housing 1, an instant heating element 2, and a water vapor separation box 3. The water vapor separation box 3 is provided with a water outlet chamber and a hot water inlet 31, a drain outlet 32, and a vent outlet 33 respectively connected to the water outlet chamber. The water outlet of the instant heating element 2 is connected to the hot water inlet 31. The faucet also includes a pressure boosting component 4, a pressure relief component 5, and a water circuit adapter 6. The pressure boosting component 4 is disposed on the fluid path downstream of the instant heating element 2 and is used to increase the pressure inside the instant heating element 2. The pressure relief component 5 and the instant heating element 2 are respectively connected to the water circuit adapter 6, and the pressure relief component 5 is used to limit the pressure inside the instant heating element 2 to below a preset value.

[0042] The faucet provided in this application has a pressurizing component 4 installed in the fluid path downstream of the instant heating element 2. The pressure increase in the instant heating element 2 upstream is achieved by utilizing the resistance generated by the pressurizing component 4 on the water flow, thus increasing the water pressure in the instant heating element 2 above atmospheric pressure. Consequently, the boiling point of the water in the instant heating element 2 is also higher than the boiling point at atmospheric pressure. The boiling point of water increases with increasing pressure. Therefore, the instant heating element 2 can heat water to a temperature of not less than 100℃ to truly boil the water. Furthermore, even if some heat is lost during the flow of boiling water towards the water vapor separator 3, the water vapor will still be heated before the water reaches a boiling point. Even with the separation box 3 in operation, the water temperature can still be maintained above 95℃, meeting the user's need for hot water. In addition, when the pressurization component 4 completely blocks the water path from the instant heating element 2 to the water vapor separation box 3 due to a malfunction, the pressure relief component 5 can limit the pressure inside the instant heating element 2 to below a preset value, playing a water path protection role and preventing the instant heating element 2 from expanding, bursting, or even being damaged due to pressure buildup, thus improving the safety of the faucet. The water path adapter 6 facilitates the connection and communication between the pressure relief component 5 and the instant heating element 2, allowing the pressure relief component 5 to release pressure from the instant heating element 2 through the water path adapter 6.

[0043] It should be noted that this application does not limit the specific value of the preset value. The value can be determined based on the actual pressure-bearing capacity of the instantaneous heating element 2 during actual production. However, the preset value should not exceed the upper limit of the actual pressure-bearing capacity of the instantaneous heating element 2 to ensure water circuit safety. Specifically, the faucet can be directly connected to the municipal water supply pipe for heating tap water, or it can be used on a water purifier to heat the filtered water. When the instantaneous heating element 2 discharges hot water to the water-vapor separation box 3, the steam generated by the hot water entering the water-vapor separation box 3 can be discharged through the exhaust port 33, while the hot water is discharged through the drain port 32, achieving water-vapor separation and reducing the jetting and water splashing phenomena caused by hot water carrying steam during discharge.

[0044] This application does not limit the location of the pressure relief component 5 in the faucet, and it can adopt any of the following embodiments:

[0045] Example 1: As Figure 1As shown, the pressure relief component 5 is connected to the fluid path upstream of the instantaneous heating element 2 and forms a parallel water circuit structure with the instantaneous heating element 2. The parallel water circuit structure of the pressure relief component 5 and the instantaneous heating element 2 means that when water enters the fluid path upstream of the instantaneous heating element 2, it can flow in two directions: one towards the instantaneous heating element 2 and the other towards the pressure relief component 5. When the water flow upstream of the instantaneous heating element 2 can be normally heated and discharged through the instantaneous heating element 2, this water circuit of the pressure relief component 5 can be cut off, preventing water from being discharged through the pressure relief component 5. When the instantaneous heating element 2 cannot continue to enter and normally discharge water due to its own malfunction or due to a malfunction of the pressurizing component 4, this water circuit of the pressure relief component 5 can be opened, allowing the water flow upstream of the instantaneous heating element 2 to be discharged and depressurized through the pressure relief component 5. In other words, the pressure relief component 5 discharges the water transported towards the instantaneous heating element 2 upstream of the instantaneous heating element 2, preventing further water intake and limiting the pressure below a preset value.

[0046] Furthermore, such as Figure 1 As shown, the faucet also includes a water inlet pipe 7 for supplying water to the instant heating element 2. The water circuit adapter 6 is a three-way connector. The water inlet pipe 7, the water inlet of the instant heating element 2, and the pressure relief component 5 are respectively connected to the three interfaces of the water circuit adapter 6, so that external water sources can enter the instant heating element 2 through the water inlet pipe 7 and the water circuit adapter 6. When depressurizing, the instant heating element 2 no longer receives water, and the water in the water inlet pipe 7 flows to the pressure relief component 5 through the water circuit adapter 6 and is discharged through the pressure relief component 5 to achieve pressure relief. The water circuit structure is simple, easy to install, and low in cost.

[0047] Example 2: Although not shown in the accompanying drawings, the pressure relief component can also be connected to the fluid path downstream of the instantaneous heating element to form a series water circuit structure with the instantaneous heating element and a parallel water circuit structure with the water vapor separator. In other words, the outlet of the instantaneous heating element is connected to the pressure relief component and the two water circuits leading to the water vapor separator. When the faucet is discharging hot water normally, the hot water output from the instantaneous heating element enters the water vapor separator through the pressurization component and is discharged from the drain outlet of the water vapor separator. At this time, the pressure relief component is in a cut-off state, and the hot water output from the instantaneous heating element cannot be discharged through the pressure relief component. However, when the pressurization component malfunctions and completely blocks the water circuit from the instantaneous heating element to the water vapor separator, the pressure inside the instantaneous heating element gradually rises, causing the pressure relief component to open, thereby allowing the water inside the instantaneous heating element to be discharged through the pressure relief component to relieve pressure. Furthermore, the outlet of the instant heating element is connected to the hot water inlet via a first water pipe and to the pressure relief assembly via a second water pipe. The water circuit adapter is a T-junction, and the outlet of the instant heating element, the first water pipe, and the second water pipe are respectively connected to the three ports of the water circuit adapter. This allows the hot water from the instant heating element to flow to the water vapor separator box through the water circuit adapter and the first water pipe during normal drainage. During pressure relief, the hot water from the instant heating element flows to the pressure relief assembly through the water circuit adapter and the second water pipe, and is discharged through the pressure relief assembly to achieve pressure relief. The water circuit structure is simple, easy to install, and low in cost.

[0048] Regarding the specific structure of the pressure relief component 5, as a preferred embodiment, such as... Figure 2 As shown, the pressure relief assembly 5 includes a first external sleeve 51 and a first one-way valve 52. The first external sleeve 51 has a first inlet port 511 and a first outlet port 512 at its two ends, respectively. The first one-way valve 52 is installed inside the first external sleeve 51. The first external sleeve 51 facilitates the connection of the pressure relief assembly 5 to its upstream and downstream water circuit structures. When the first one-way valve 52 is open, it connects the first inlet port 511 and the first outlet port 512, allowing the instantaneous heating element 2 to release pressure through the pressure relief assembly 5. When the first one-way valve 52 is not open, it cuts off the first inlet port 511 and the first outlet port 512.

[0049] Furthermore, such as Figure 3 As shown, the first one-way valve 52 includes a valve housing 521 and a valve core 522. The valve core 522 is movably disposed within the valve housing 521 and has a water-blocking position that cuts off the communication between the first water inlet port 511 and the first water outlet port 512, and a conducting position that connects the first water inlet port 511 and the first water outlet port 512. When the valve core 522 moves from the water-blocking position to the conducting position, it is confined by the valve housing 521 to the conducting position, thereby keeping the first water inlet port 511 and the first water outlet port 512 in a connected state. Figure 2 and Figure 3 The diagram shows the state of valve core 522 when it is in the water-blocking position. In a specific implementation, a spring 523 can be installed between the valve body 521 and the valve core 522. The spring force of the spring 523 keeps the valve core 522 in the water-blocking position. When the valve core 522 is subjected to greater water pressure, it overcomes the spring force of the spring 523 and moves towards the conduction position, thus being confined to the conduction position. This keeps the first inlet port 511 and the first outlet port 512 connected. In other words, after the valve core 522 moves from the water-blocking position to the conduction position, it cannot return to the water-blocking position. That is, the first one-way valve 52 is a non-self-resetting structure. After the first one-way valve 52 is opened, it is in the normally open state, allowing the pressure inside the instantaneous heating element 2 to quickly return to normal pressure, effectively ensuring the safety of the entire system. Figure 4 The image shows the state when valve core 522 is confined to the open position. Figure 4 The middle arrow indicates the fluid path of the first check valve 52 when the valve core 522 is confined to the open position. This application does not limit the manner in which the valve core 522 is confined to the open position. For example, the valve core 522 may be confined by engaging with the valve housing 521 when it moves to the open position. Of course, other methods may also be used to confine the valve core 522 to the open position.

[0050] This application does not limit the structure of the booster assembly 4, which can adopt any of the following embodiments:

[0051] Example 3: Figure 5 As shown, the pressurization component 4 is configured as a second one-way valve 41 installed inside the hot water inlet 31. When the second one-way valve 41 is not open, it blocks the hot water inlet 31, cutting off the connection between the instantaneous heating element 2 and the water vapor separator 3. The obstruction of the water flow by the second one-way valve 41 increases the pressure inside the instantaneous heating element 2, raising the boiling point of the water. When the second one-way valve 41 is opened under water pressure, the hot water discharged from the instantaneous heating element 2 can enter the water vapor separator 3. Moreover, by installing the second one-way valve 41 inside the hot water inlet 31, the pressure in the pipeline upstream of the water vapor separator 3 is increased, resulting in less heat loss during the flow of hot water from the instantaneous heating element 2 to the water vapor separator 3, thus maintaining a higher temperature.

[0052] Example 4: Figures 6 to 9 As shown, one end of the pressurization component 4 is connected to the outlet of the instantaneous heating element 2, and the other end is connected to the water vapor separator 3. Unlike the scheme in Embodiment 3 where the pressurization component 4 is located inside the water vapor separator 3, in this embodiment, the pressurization component 4 is connected to the outside of the water vapor separator 3, effectively improving the ease of assembly of the pressurization component 4. Regarding the specific structure of the pressurization component 4 in this embodiment, it can adopt any of the following examples:

[0053] Example 1: such as Figure 6 and Figure 7 As shown, the pressurization assembly 4 includes a second external sleeve 42 and a third one-way valve 43. The second external sleeve 42 has a second inlet port 421 and a second outlet port 422 at its two ends. The second inlet port 421 is connected to the outlet of the instantaneous heating element 2, and the second outlet port 422 is connected to the hot water inlet 31. The third one-way valve 43 is installed inside the second external sleeve 42. The second external sleeve 42 facilitates the connection of the pressurization assembly 4 to its upstream and downstream water circuit structures. When the third one-way valve 43 is open, it connects the second inlet port 421 and the second outlet port 422, allowing hot water from the instantaneous heating element 2 to enter the water-vapor separator 3 through the pressurization assembly 4. When the third one-way valve 43 is closed, it cuts off the second inlet port 421 and the second outlet port 422, thereby cutting off the connection between the instantaneous heating element 2 and the water-vapor separator 3. To facilitate the connection between the second external sleeve 42 and the upstream water circuit components, a connecting pipe 423 can be installed at the second water inlet port 421.

[0054] Example 2: such as Figure 8As shown, the pressurization component 4 includes at least one valve body 44, which has a third inlet port 441, a third outlet port 442, and a Tesla valve channel 443 that connects the third inlet port 441 to the third outlet port 442 in reverse. The third inlet port 441 is connected to the outlet of the instantaneous heating element 2, and the third outlet port 442 is connected to the hot water inlet 31. Specifically, the Tesla valve channel 443 can be connected to the outlet of the instantaneous heating element 2 in reverse through the third inlet port 441 and to the hot water inlet 31 in forward through the third outlet port 442. When the instantaneous heating element 2 discharges hot water to the water-vapor separator 3, the hot water flows through the Tesla valve channel 443 and is resisted by the Tesla valve channel 443, thereby pressurizing the water upstream of the Tesla valve channel 443. The boiling point of the water in the instantaneous heating element 2 rises, the heating temperature of the instantaneous heating element 2 is higher, and the water flows to the water-vapor separator 3 after passing through the Tesla valve channel 443. In addition, as Figure 9 As shown, multiple valve bodies 44 can be connected in series to allow different pressures and intensities to be obtained upstream of the Tesla valve channel 443, which can meet different boiling point temperature requirements.
