In addition, the terms "first" and "second" are used only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may include one or more of the features explicitly or implicitly. Moreover, the terms "first", "second", etc. are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described here can be implemented in an order other than those illustrated or described here.

[0029] The present application provides a faucet, which is particularly suitable for reducing stagnant water in the faucet.

[0030] See also Figure 1-3 The present application provides a faucet, which includes a start switch 106 and a reset switch 107, a start valve stem 101, a reset valve stem 102 and a reset arm 103. The start valve stem 101 and the reset valve stem 102 are arranged at an angle, the start valve stem 101 is used to cooperate with the start switch 106, the reset valve stem 102 is used to cooperate with the reset switch 107, and the reset arm 103 is arranged between the reset valve stem 102 and the reset switch 107. When the reset valve stem 102 cooperates with one end of the reset arm 103, the other end of the reset arm 103 cooperates with the reset switch 107. Through the coordinated design of the start switch 106 and the reset switch 107, the start valve stem 101, the reset valve stem 102 and the reset arm 103, the user can control the start and reset of the faucet through simple operations. The reset arm 103 is arranged between the reset valve stem 102 and the reset switch 107. Through the matching design of the reset arm 103, the correct matching between the reset valve stem 102 and the reset switch 107 can be ensured during the resetting process, thereby ensuring the safety and reliability of the faucet when resetting.

[0031] It is understandable that in some cases, using a faucet will retain stagnant water, such as insufficient water pressure and too long a length of the water outlet pipe 2. The stagnant water stays in the water pipe for too long and is prone to breed bacteria, that is, the water obtained by the user from the faucet contains "new water" and "old water".

[0032] Specifically, the faucet includes components such as a valve assembly 1, a water outlet pipe 2, a display device 3, a shell 4, a handle 5 and a handwheel 6. When a user turns the handle 5, the handle 5 drives the handwheel 6, thereby changing the working state of the valve assembly 1. The display device 3 can display information about retained water and water temperature, water flow, water pressure and other information. The valve assembly 1 is used to start and stop the water outlet of the water outlet pipe 2, and the valve assembly 1 is arranged inside the shell 4.

[0034] Specifically, when the start valve stem 101 cooperates with the start switch 106, the start switch 106 records data, that is, the current faucet usage count = the original faucet usage count + 1, and when the reset valve stem 102 cooperates with the reset switch 107, the current faucet usage count is reset to zero.

[0035] In one embodiment, the start valve stem 101 is arranged along a first direction L1, and the reset valve stem 102 is arranged along a second direction L2, the first direction L1 is perpendicular to the second direction L2, and the start valve stem 101 and the reset valve stem 102 are fixedly connected to the valve core. When the faucet is closed, the start valve stem 101 and the reset valve stem 102 do not contact the start switch 106 and the reset switch 107, and the water outlet pipe 2 does not discharge water; when the faucet is opened, the start valve stem 101 is arranged in a direction opposite to the second direction L2, and the reset valve stem 102 is arranged in the first direction L1, the start valve stem 101 contacts and cooperates with the start switch 106, and water flows out of the water outlet pipe 2; when the faucet is reset, the start valve stem 101 is arranged in the second direction L2, and the reset valve stem 102 is arranged in a direction opposite to the first direction L1, and the reset valve stem 102 drives the reset arm 103, and the reset arm 103 contacts and cooperates with the reset valve stem 102, and the reset arm 103 contacts and cooperates with the reset switch 107.

[0037] Specifically, when the faucet is in the reset state, it is characterized that the faucet has been cleaned, and the number of times the faucet has been used is reset to zero.

[0038] Furthermore, a reset bracket 104 is included, and the reset arm 103 is rotatably connected to the reset bracket 104. When the faucet is reset, the reset valve stem 102 is coaxially arranged with the reset bracket 104. The design of the rotatable connection between the reset bracket 104 and the reset arm 103 can ensure the stability and reliability of the reset arm 103 during the reset process. The reset valve stem 102 is coaxially arranged with the reset bracket 104, which can ensure that the reset valve stem 102 is in the same position as the reset bracket 104 in the reset state, thereby making the reset action more accurate and controllable.

[0039] Specifically, the reset bracket 104 is fixed on the inner wall of the valve assembly 1 , the reset arm 103 is in contact with the reset arm, and the reset arm is arranged along the first direction L1 .

When the second reset portion 1032 is in contact with the reset switch 107, the boss mechanism 1034 is engaged with the reset bracket 104. Through the engagement design of the boss mechanism 1034 and the reset bracket 104, the contact area between the reset arm 103 and the reset bracket 104 can be increased, the stability and reliability of the connection can be improved, and the reset arm 103 can be effectively prevented from excessive rotation during the reset process.

[0041] In one embodiment, the first reset portion 1031 contacts and cooperates with the reset valve stem 102 , and the second reset portion 1032 contacts and cooperates with the reset switch 107 .

[0043] Specifically, when the second reset portion 1032 is fitted with the reset switch 107 , the boss mechanism 1034 is engaged with the reset bracket 104 , and the relative distance between the boss mechanism 1034 and the valve core is smaller than the relative distance between the reset bracket 104 and the valve core.

[0044] In one embodiment, the rotation range of the boss mechanism 1034 is 0° to 90°.

[0045] In another embodiment, the rotation range of the boss mechanism 1034 is 0° to 60°.

[0046] Specifically, the reset arm 103 further includes a third reset portion 1033, the first reset portion 1031, the third reset portion 1033 and the second reset portion 1032 are connected in sequence, and the boss mechanism 1034 is disposed between the first reset portion 1031 and the third reset portion 1033. The first reset portion 1031, the third reset portion 1033 and the second reset portion 1032 are connected in sequence, thereby increasing the overall stability of the reset arm 103, and the design of the boss mechanism 1034 can ensure that the reset arm 103 maintains a correct angle and position during the reset process.

[0047] In one embodiment, the reset arm 103 is a “Z” shaped reset arm.

[0048] Specifically, the first reset portion 1031, the second reset portion 1032 and the third reset portion 1033 are integrally formed. The reset arm 103 includes a first transition portion and a second transition portion, the first transition portion is arranged between the first reset portion 1031 and the third reset portion 1033, the second reset portion 1032 is arranged between the third reset portion 1033 and the second reset portion 1032, and the relative distance between the first transition portion and the valve core is smaller than the relative distance between the second transition portion and the valve core. The boss mechanism 1034 is arranged on the first transition portion.

[0049] Furthermore, it also includes a reset base 105 and a support shaft 1051, the reset base 105 is fixedly connected to the support shaft 1051, the reset arm 103 is sleeved on the support shaft 1051, and a reset through hole 1035 is provided on the reset arm 103, and the inner diameter of the reset through hole 1035 is greater than or equal to the outer diameter of the support shaft 1051. The fixed connection between the reset base 105 and the support shaft 1051 enhances the overall stability of the reset arm 103. The support shaft 1051 serves as the support point of the reset arm 103, and the support shaft 1051 is fixed on the reset base 105 to effectively support the movement of the reset arm 103, reduce shaking and swaying, and the inner diameter of the reset through hole 1035 is greater than or equal to the outer diameter of the support shaft 1051, which ensures the rotational freedom of the reset arm 103 on the support shaft 1051, thereby increasing the flexibility and adjustability of the reset arm 103.

[0050] Specifically, the reset base 105 is arranged along the second direction L2, the reset arm 103 can rotate relative to the reset base 105, the plane pointed to by the support shaft 1051 is perpendicular to the second direction L2, and the reset through hole 1035 is sleeved on the support shaft 1051. The difference between the inner diameter of the reset through hole 1035 and the outer diameter of the support shaft 1051 is 0.2mm-5mm.

[0051] In one embodiment, the height of the reset base 105 is less than or equal to the height of the reset bracket 104 .

[0052] Furthermore, the reset through hole 1035 is arranged between the second reset portion 1032 and the third reset portion 1033, and the reset through hole 1035 includes a long axis and a short axis, the direction of the long axis is perpendicular to the first direction L1, and the direction of the short axis is parallel to the first direction L1. The long axis and the short axis can provide additional support and guidance in the reset action, so that the reset arm 103 remains stable during the reset process, and the vertical direction of the long axis and the horizontal direction of the short axis cooperate with each other, effectively limiting the range of motion of the reset arm 103, avoiding shaking and swaying, and can also effectively reduce the friction and wear between the reset arm 103 and the through hole, thereby extending the service life of the reset arm 103.

[0053] Specifically, the reset through hole 1035 is disposed on the second turning portion, and the length of the major axis of the reset through hole 1035 is 1.1-2 times the length of the minor axis.

[0054] In one embodiment, the reset through hole 1035 is oval in shape.

[0056] Specifically, the rotation angle of the start valve stem 101 is 0°-180°, and the rotation angle of the reset valve stem 102 is 0°-180°. The rotation angles of the start valve stem 101 and the reset valve stem 102 are the same, which reduces the complexity of use. The start valve stem 101 and the reset valve stem 102 can provide a clear operating range, and the user can easily control the opening and closing of the valve. This design makes the operation more intuitive and convenient, and can also reduce the types and costs of parts.

[0057] Specifically, the start valve stem 101 and the reset valve stem 102 have the same rotation angle during the rotation process. Both the start valve stem 101 and the reset valve stem 102 rotate as the handle 5 rotates.

[0058] Furthermore, it also includes an indicator device 109, which is electrically connected to the start switch 106, and the start switch 106 is a water retention counter. The indicator device 109 can provide real-time feedback and indicate the use status of the faucet.

Through the counting information displayed by the indicator device 109, the user can understand his or her own water use situation, which is convenient for monitoring and managing the use of water resources.

[0059] In one embodiment, the water storage capacity V of the retention water tank and the retention water volume v of each tap are obtained, and a first retention water number threshold A and a second retention water number threshold B are determined, wherein the first retention water number threshold A is equal to the ratio of the water storage capacity V of the retention water tank to the retention water volume v of each tap, and the second retention water number threshold B is equal to the product of the first retention water number threshold A and the retention water coefficient a, wherein the retention water coefficient a>1.

[0060] Specifically, when the current number of retained water times is less than or equal to the first retained water times threshold value A, the indication state of the indication device 109 is that the indicator light is off; when the current number of retained water times is between the first retained water times threshold value A and the second retained water times threshold value B, the indication state of the indication device 109 is that the indicator light is always on; when the current number of retained water times is greater than or equal to the second retained water times threshold value B, the indication state of the indication device 109 is that the indicator light flashes.

[0061] Specifically, it also includes a driving device 108, which is respectively connected to the start switch 106, the reset switch 107, the indicating device 109 and the display device 3. The driving device 108 is used to provide a power source for each component, and the display device 3 can also display the use of the driving device 108.

[0062] Furthermore, a water tank is included, and the reset switch 107 is connected to the drain port of the water tank. The water tank is used to store a certain amount of retained water, thereby reducing the use of retained water by users. The reset switch 107 is connected to the drain port of the water tank to achieve the drainage function. When the user needs to clean or maintain the water tank, the water in the water tank can be drained by operating the reset switch 107, which is convenient for cleaning and maintenance.

[0063] Specifically, the water tank is used to store the retained water to reduce the probability of the retained water flowing into the water outlet pipe 2, and the water tank is connected to the valve assembly 1. After the water is drained from the drain outlet of the water tank, the reset switch 107 obtains the current state of the water tank and resets the number of times the faucet is used to zero.

[0064] Furthermore, a display device 3 is included, and the display device 3 is respectively connected to the start switch 106 and the reset switch 107. The display device 3 is connected to the start switch 106, and the user can monitor the opening and closing status of the faucet in real time to understand his water use situation. The display device 3 can also display the current water flow status to help the user to grasp the water use situation in time.

[0065] Specifically, the display device 3 is exposed in the user's field of vision, and the display device 3 can display both the current usage status of the faucet and the current water flow information, so that the user can understand the usage status of the faucet in multiple dimensions.

[0066] Specifically, the first reset portion 1031 includes a first contact surface, the second reset portion 1032 includes a second contact surface, the start switch 106 includes a third contact surface 1061, and the reset switch 107 includes a fourth contact surface 1071.

By configuring the first contact surface to be in the same shape as the third contact surface 1061, and configuring the second contact surface to be in the same shape as the fourth contact surface 1071, the contact surfaces can be more closely fitted to reduce wear during operation, and the actions of the start switch 106 and the reset switch 107 can be more accurate to avoid misoperation.

[0067] In one embodiment, the reset valve stem 102 contacts the first contact surface, thereby driving the reset arm 103 to rotate, and the second contact surface contacts the reset switch 107, thereby activating the reset switch 107 and updating the indication state of the indication device 109.

[0068] The following describes the working process of the faucet in the embodiment of the present application in combination with a specific application scenario, as follows:

[0069] The user changes the working state of the valve assembly 1 by turning the handle 5, and starts and stops the water flow from the water outlet pipe 2. When the faucet is closed, the start valve stem 101 and the reset valve stem 102 are not in contact with the start switch 106 and the reset switch 107, and water does not flow from the water outlet pipe 2; when the faucet is open, the start valve stem 101 contacts the start switch 106, and water flows from the water outlet pipe 2. When the faucet is reset, the reset arm 103 contacts the reset switch 107, and the number of times the faucet is used is reset to zero, indicating that the faucet is currently in a clean state.
