Description

Technical Field

[0001] This application relates to the field of electric water faucet technology, and in particular to an electric water faucet with anti-dry-burning feature. Background Technology

[0002] Existing electric water faucets generally use water pressure to drive a pressure diaphragm, causing the moving contact to make contact with the stationary contact, thus connecting the control circuit. Because electric water faucets are open-type water heaters, under normal conditions, when the faucet is closed, the water tank is unpressurized, with internal pressure close to zero, allowing the water in the pressure diaphragm to release into the tank and disconnect the power. However, during use, scale and other debris can clog the spout. Once the spout is clogged, when switching the faucet from the heating position to the off position, the water in the pressure diaphragm cannot be released into the tank. This results in the control circuit remaining conductive even though the faucet is closed, leading to dry burning and a safety hazard.

[0003] Therefore, considering the aforementioned technical problems, it is necessary to propose a new technical solution. Summary of the Invention

[0004] The purpose of this application is to address at least one of the shortcomings of the existing technology; therefore, a dry-burning-proof electric water faucet is proposed. The technical solution is as follows: An anti-dry-burning electric water faucet includes a main body, within which a heating chamber, a pressure detection channel, and a water inlet channel are provided. The heating chamber, the pressure detection channel, and the water inlet channel are connected by a valve core assembly. A handle connected to the valve core assembly is provided on one side of the main body. A pressure diaphragm and a moving contact are provided at the pressure detection channel. The electric water faucet also includes a push rod and a disconnecting contact. The handle has a closed position and a hot water position. When the handle is in the hot water position, the disconnecting contact is in its initial position, and the pressure diaphragm, when subjected to force, can drive the moving contact to connect with the disconnecting contact. When the handle is in the closed position, under the action of the handle, the push rod drives the disconnecting contact to move a set distance away from the moving contact, so that when the pressure diaphragm is subjected to force, the moving contact and the disconnecting contact are not connected.

[0005] The aforementioned anti-dry-burning electric water faucet, by setting the original static contact as a movable separation contact, utilizes the cooperation between the push rod and the handle to ensure that when the handle is in the closed position, the separation contact is driven to move a set distance away from the moving contact from its initial position. This ensures that the moving contact and the separation contact do not connect regardless of whether the pressure diaphragm is under pressure, thus effectively preventing dry burning and making the electric water faucet safer and more reliable to use.

[0006] In one embodiment, the electric water faucet further includes a separating contact spring, which is disposed within the main body. One end of the separating contact spring is fixed, and the other end is a free end. The separating contact is disposed on the separating contact spring. When the handle is rotated to the closed position, the push rod is driven by the handle to move the free end a set distance away from the moving contact.

[0007] In one embodiment, the separating contact spring is provided with an inclined surface, the end of the inclined surface facing the moving contact is inclined away from the push rod, and one end of the push rod can abut against the inclined surface. This design allows the free end of the separating contact spring to move downward when the push rod is driven forward by the handle, thereby causing the separating contact to move away from the moving contact.

[0008] In one embodiment, the main body is provided with a heating chamber and a wiring board, the heating cavity is disposed in the heating chamber, the wiring board is fixedly connected to the heating chamber, and one end of the separation contact spring is fixedly connected to the wiring board.

[0009] In one embodiment, the pressure detection channel is disposed in the heating chamber, and the heating chamber is further provided with a pressure chamber communicating with the pressure detection channel. The pressure diaphragm is fixed to the pressure chamber by the wiring plate. When the handle is in the hot water position, the water inlet channel is connected to the heating chamber and the pressure detection channel respectively. The water flow entering the pressure detection channel drives the pressure diaphragm to deform, thereby driving the moving contact to pass through the wiring plate and contact the separating contact.

[0010] In one embodiment, the main body is provided with a push rod cavity, one end of which communicates with the inner cavity of the main body, and the other end of which extends toward the handle and penetrates the main body. The push rod is movably disposed in the push rod cavity. The side of the handle facing the push rod is provided with a protrusion and a recess. When the handle is in the closed position, the push rod abuts against the protrusion. When the handle is in the hot water position, the push rod abuts against the recess.

[0011] In one embodiment, the electric water faucet also includes a resilient element capable of applying a force toward the handle to the push rod. This design allows the push rod to automatically return to its original position when no force is applied.

[0012] In one embodiment, the inner wall of the push rod cavity is provided with a first stop surface, and the circumferential wall of the push rod is provided with a second stop surface. The second stop surface is located between the first stop surface and the handle, and the elastic element is located between the first stop surface and the second stop surface.

[0013] In one embodiment, the handle also has a cold water position. When the handle is in the cold water position, the push rod abuts against the protrusion, causing the push rod to move the disengagement contact a predetermined distance away from the moving contact. This design ensures that the moving contact and the disengagement contact remain separated when the handle is rotated to the cold water position or the closed position.

[0014] In one embodiment, a heating element is provided inside the heating cavity, and the heating element, the moving contact, and the separating contact are respectively connected to a control circuit. Attached Figure Description

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0018] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the specification of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0020] This application provides an anti-dry-burning electric water faucet, which includes a main body 1. The main body 1 contains a heating chamber 21, a pressure detection channel 22, and a water inlet channel 31. The heating chamber 21, the pressure detection channel 22, and the water inlet channel 31 are connected and controlled by a valve core assembly 4. A handle 5 connected to the valve core assembly 4 is provided on one side of the main body 1. A pressure diaphragm 6 and a moving contact 71 are provided at the pressure detection channel 22. The electric water faucet also includes a push rod 8 and a disconnecting contact 91. The handle 5 has a closed position A and a hot water position B. When the handle 5 is in the hot water position B, the disconnecting contact 91 is in its initial position, and the pressure diaphragm 6 is stressed enough to connect the moving contact 71 to the disconnecting contact 91. When the handle 5 is in the closed position A, under the action of the handle 5, the push rod 8 drives the disconnecting contact 91 to move a set distance away from the moving contact 71, so that the moving contact 71 and the disconnecting contact 91 are not connected when the pressure diaphragm 6 is stressed.

[0021] The aforementioned anti-dry-burning electric water faucet, by setting the original static contact as a movable separation contact 91, utilizes the cooperation between the push rod 8 and the handle 5 to ensure that when the handle 5 is in the closed position A, the separation contact 91 is driven to move a set distance away from the moving contact 71 from its initial position. This ensures that regardless of whether the pressure diaphragm 6 is under force, the moving contact 71 and the separation contact 91 are not connected, thereby effectively preventing dry burning and making the electric water faucet safer and more reliable to use.

[0022] like Figure 1 , Figure 2 or Figure 4 As shown in the figure, an embodiment is schematically illustrated. The electric water faucet is a vertical electric water faucet, which includes a vertical body 1. A heating chamber 2 is provided inside the body 1, and a heating cavity 21 is provided inside the heating chamber 2. The heating chamber 2 is located near the top of the inner cavity of the body 1, and a receiving cavity 13 is formed below the heating chamber 2 inside the body 1. A water inlet 3 is provided at the lower end of the body 1 for water inlet, and a water inlet channel 31 is provided at the water inlet 3. One end of the water inlet channel 31 is connected to an external water source, and the other end extends towards the valve core assembly 4. A water outlet 10, such as a water outlet elbow, is provided at the upper end of the body 1 for water outlet, which is connected to the heating cavity 21.

[0023] A heating element 25 is disposed within the heating cavity 21, and the heating element 25 is electrically connected to the control circuit. The heating element 25 is preferably a heating tube, such as... Figure 2 or Figure 5As shown. The valve core assembly 4 is disposed on one side of the main body 1, and the handle 5 is disposed on the side of the valve core assembly 4 opposite to the heating chamber 2. A flow channel 14 is provided on the circumferential wall of the heating chamber 2 near its lower end. One end of the flow channel 14 communicates with the heating cavity 21, and the other end extends towards the valve core assembly 4 and penetrates the circumferential wall of the heating chamber 2. The pressure detection channel 22 is disposed near the bottom of the heating chamber 2. One end of the pressure detection channel 22 penetrates the bottom of the heating chamber 2, and the other end extends towards the valve core assembly 4 and penetrates the circumferential wall of the heating chamber 2.

[0024] The valve core assembly 4 is rotatably mounted and has a flow channel assembly. When the handle 5 is rotated, causing the valve core assembly 4 to rotate to the closed position A, as... Figure 1 and Figure 5 As shown, at the position, the valve core assembly 4 blocks the water inlet channel 31 and the flow channel 14; when the handle 5 is rotated, causing the valve core assembly 4 to rotate to the cold water position C, as... Figure 1 As shown, the flow channel assembly within the valve core assembly 4 connects the water inlet channel 31 and the flow channel 14; when the handle 5 is rotated, causing the valve core assembly 4 to rotate to the hot water position B, as... Figure 1 and Figure 2 As shown, the flow channel assembly within the valve core assembly 4 connects the water inlet channel 31 to the flow channel 14 and the pressure detection channel 22, respectively. Since the valve core assembly 4, the handle 5, the water inlet component 3, the water outlet component 10, the heating element 25, and the control circuit are all conventional technologies, and their specific structures and configurations are not the focus of this application, they will not be described further in this application.

[0025] The electric water faucet also includes a release contact spring 9, preferably an elastic and conductive release contact spring 9, which can undergo a certain bending deformation under force. The release contact spring 9 is disposed within the main body 1, with one end of the release contact spring 9 fixed and the other end being a free end. The release contact 91 is disposed on the release contact spring 9. When the handle 5 is rotated to the closed position A, the push rod 8, under the action of the handle 5, drives the free end to move a set distance away from the moving contact 71. Figure 2 and Figure 3As shown in the figure, an embodiment is schematically illustrated, in which a pressure cavity 23 is provided at the bottom of the heating chamber 2. Specifically, a receiving groove is provided at the bottom of the heating chamber 2, and a wiring plate 24 is embedded and fixed in the receiving groove. The wiring plate 24 and the receiving groove form the pressure cavity 23. The pressure detection channel 22 communicates with the receiving groove at the bottom of the receiving groove. The wiring plate 24 is provided with a through hole 241 communicating with the pressure cavity 23. The pressure diaphragm 6 is disposed in the receiving groove, and part of the structure of the wiring plate 24 is embedded in the receiving groove to press and fix the edge of the pressure diaphragm 6. On the side of the wiring plate 24 facing the pressure diaphragm 6, a chamber is provided in the middle part corresponding to the pressure diaphragm 6 to allow the pressure diaphragm 6 to deform, and the through hole 241 communicates with the chamber. A push rod 61 is provided on the side of the pressure diaphragm 6 facing away from the pressure detection channel 22, and the push rod 61 passes through the through hole 241 of the wiring board 24. The moving contact 71 is provided at the end of the push rod 61 facing away from the pressure diaphragm 6 and is connected to the control circuit.

[0026] The separating contact spring 9 is disposed below the terminal block 24, and one end of the separating contact spring 9 is fixedly connected to the terminal block 24, such as... Figure 2 and Figure 3 As shown. The other end of the separating contact spring 9 extends towards the handle 5 to the through hole 241. The separating contact 91 is disposed on the separating contact spring 9 and located at the bottom end of the through hole 241. In specific implementation, when the handle 5 is rotated, causing the valve core assembly 4 to rotate to the hot water position B, the flow channel group in the valve core assembly 4 makes the water inlet channel 31 connected to the flow channel 14 and the pressure detection channel 22 respectively. The water flow X flows through the pressure detection channel 22 to the pressure diaphragm 6. The pressure diaphragm 6 deforms towards the separating contact 91 under the drive of the water flow X, thereby driving the push rod 61 to move the moving contact 71 towards the separating contact 91 until the moving contact 71 contacts the separating contact 91 to realize the control circuit conduction. The heating element 25 starts to work to heat the water flow X in the heating chamber 21.

[0027] The moving contact 71 can be disposed on a moving contact spring 7, which is elastic and conductive. One end of the moving contact spring 7 is fixedly connected to the terminal block 24, and the moving contact 71 is disposed near the other end of the moving contact spring 7, for example... Figure 4As shown. The moving contact 71 is connected to the control circuit via the moving contact spring 7. Since the way the moving contact spring 7 is connected to the control circuit and the way the moving contact 71 is positioned on the moving contact spring 7 are conventional technologies, and are not the focus of this application, they will not be described further in this application. The separating contact spring 9 is connected to the control circuit so that the separating contact 91 is connected to the control circuit. Since the way the separating contact spring 9 is connected to the control circuit and the way the separating contact 91 is positioned on the separating contact spring 9 are conventional technologies, and are not the focus of this application, they will not be described further in this application.

[0028] The separating contact spring 9 is provided with an inclined surface 921. The end of the inclined surface 921 facing the moving contact 71 is inclined away from the push rod 8, and one end of the push rod 8 can abut against the inclined surface 921. For example Figures 2 to 6 In the schematically illustrated embodiment, the separating contact spring 9 has a protrusion 92 near its free end on the side facing the moving contact 71, and the protrusion 92 forms an inclined surface 921 on the side facing the push rod 8. The main body 1 has a push rod cavity 11 below the valve core assembly 4, and the axis of the push rod cavity 11 is aligned with the axis of the valve core assembly 4. One end of the push rod cavity 11 communicates with the inner cavity of the main body 1, and the other end extends towards the handle 5 and penetrates the main body 1. The push rod 8 is movably disposed within the push rod cavity 11. The handle 5 has a protrusion 511 and a recess 512 on the side facing the push rod 8, for example... Figure 4 and Figure 7As schematically shown, the handle 5 includes a main body 51 and a handle portion 52. An arc-shaped protrusion is provided on the inner side of the main body 51. The arc-shaped protrusion includes a high platform and a low platform along its extending direction, with a smooth transition between the high platform and the low platform, thereby forming the protrusion 511 and the recess 512 on the inner side of the main body 51. The position and size of the protrusion 511 and the recess 512 are such that when the handle 5 is rotated to the closed position A, the push rod 8 abuts against the protrusion 511, and when the handle 5 is rotated to the hot water position B, the push rod 8 abuts against the recess 512. This design allows the push rod 8 to be pushed forward and abut against the inclined surface 921 as the handle 5 rotates to its protrusion 511. Under the action of the inclined surface 921, the free end of the separating contact spring 9 gradually moves downward, thereby driving the separating contact 91 to move away from the moving contact 71 until the separating contact 91 deviates from the initial position by a set distance. The inclination angle of the inclined surface 921 and the travel distance of the push rod 8 are designed to ensure that when the handle 5 is rotated to the closed position A, there is a set distance between the maximum movement range of the separating contact 91 and the moving contact 71. The maximum movement range of the moving contact 71, i.e., the activity distance, is mainly affected by the initial distance H1 between the bottom wall of the chamber on the wiring board 24 that causes the pressure diaphragm 6 to deform and the pressure diaphragm 6. For example, when the initial distance H1 is 1.8mm, the maximum movement range of the moving contact 71 is also 1.8mm. Assuming the distance between the separating contact 91 and its initial position is set to 1.2mm, and the distance between the moving contact 71 and the separating contact 91 is set to 1.7mm when the pressure diaphragm 6 and the separating contact spring 9 are in their initial states, then when the handle 5 is rotated to the closed position A, the push rod 8 drives the separating contact spring 9 to move the separating contact 91 downwards by 1.2mm. If the pressure diaphragm 6 is in its initial state at this time, the distance H2 between the separating contact 91 and the moving contact 71 is 2.9mm, which is much greater than the maximum movement of the moving contact 71. Therefore, when the handle is in the closed position A, regardless of whether the pressure diaphragm 6 is under force, the moving contact 71 and the separating contact 91 are never connected, thus effectively preventing dry burning and making the electric water faucet safer and more reliable to use.

[0029] In one embodiment, an arc-shaped groove 513 may be provided on the end faces of the protrusion 511 and the recess 512, such as... Figure 4 and Figure 7As shown, one end of the push rod 8 slides within the arc-shaped groove 513. This design provides a certain limit to the push rod 8, ensuring more stable movement of the push rod 8.

[0030] In one embodiment, an elastic element 12 can also be provided to apply a force toward the handle 5 to the push rod 8, so that the push rod 8 can be automatically reset when no force is applied. For example Figure 2 and Figure 3 In the schematic embodiment shown, the push rod cavity 11 is designed with a variable diameter, so that the inner wall of the push rod cavity 11 forms a first stop surface 111. The push rod 8 is designed with a variable diameter, so that a second stop surface 81 is formed on the circumferential wall of the push rod 8. The smaller diameter section of the push rod 8 faces the separating contact spring 9, and the second stop surface 81 is located between the first stop surface 111 and the handle 5. The elastic element 12 is located between the first stop surface 111 and the second stop surface 81. The elastic element 12 is preferably a spring, sleeved on the push rod 8. When the handle 5 is rotated to the closed position A, the handle 5 pushes the push rod 8 towards the separating contact spring 9, the spring is compressed and deformed, and applies elastic pressure to the second stop surface 81 towards the handle 5. When the handle 5 is rotated to the hot water position B, under the action of the elastic pressure of the spring, the push rod 8 moves towards the handle 5 to complete the reset, and the separating contact 91 also resets to the initial position.

[0031] In one embodiment, the handle 5 also has a cold water position C, such as Figure 1 As shown. Preferably, the handle 5 is designed such that when the handle 5 is in the cold water position C, the push rod 8 can also abut against the protrusion 511, thereby allowing the push rod 8 to drive the separation contact 91 to deviate a set distance away from the moving contact 71. This design ensures that when the handle 5 is rotated to the cold water position C or the closed position A, the moving contact 71 and the separation contact 91 are always in a separated state.

[0032] The technical features of the above embodiments can be combined in any way. For the sake of brevity, 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.

[0033] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
