  • In order to further clarify the technical problems to be solved by the present disclosure, the technical solutions adopted by the present disclosure and the beneficial effects achieved by the present disclosure, the present disclosure will be further described in detail below with reference to the drawings and the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are not intended to limit the present disclosure.

  • A guide passage 101 is formed inside the housing 110. Furthermore, the housing 110 may be fabricated from insulating materials such as plastic.
  • The first conductive unit 120 is mounted to the housing 110 through an elastic member 140 and extends into the guide passage 101. The elastic member 140 supports the first conductive unit 120 to reciprocate along the guide passage 101. The second conductive unit 130 is mounted to the housing 110 and extends into the guide passage 101, and the first conductive unit 120 and the second conductive unit 130 are spaced apart by a certain distance in the guide passage 101.
  • When in use, the first conductive unit 120 is pressed to move toward the second conductive unit 130 in the guide passage 101 and causes the elastic member 140 to deform, thereby electrically conducting the first conductive unit 120 and the second conductive unit 130.
  • To be specific, the first conductive unit 120 may be a first conductive post, and the elastic member 140 is provided with an open end. Alternatively, the elastic member 140 may be a rubber tube provided with an open end.
  • The elastic member 140 is used to support the first conductive post to reciprocate along the guide passage 101, and the open end of the elastic member 140 is tightly sleeved on the outer surface of the housing 110 so that a closed space 102 is formed between the elastic member 140 and the housing 110.
  • In this embodiment, the first conductive post sequentially passes through the bottom of the elastic member 140 and the closed space 102 and extends into the guide passage 101. The first conductive post is pressed to move along the guide passage 101, and the first conductive post causes the elastic member 140 to deform. Preferably but not restrictively, the bottom end of the elastic member 140, which is opposite to the open end, may have another opening and may be tightly sleeved on the first conductive post so as to move together with the first conductive post.
  • The second conductive unit 130 includes a second conductive post 131, a conductive spring 132, and a wire 133 that are electrically connected in sequence. The second conductive post 131 and the conductive spring 132 are both accommodated in the guide passage 101. One end of the wire 133 extends into the guide passage 101 and is hermetically and fixedly connected with the housing 110, and the other end extends out of the guide passage 101 and is electrically connected with an external circuit. In this embodiment, the second conductive post 131 is spaced apart from the first conductive post by a certain distance within the guide passage 101.

As an example, the limiting protrusion may be an annular protrusion or include at least one embossment.
  • It should be understood that since the limiting protrusion is provided on the inner surface of the guide passage 101, the diameter of the first conductive post may be smaller than the diameter of the second conductive post 131, so that the first conductive post can avoid the limiting projection to directly abut against the second conductive post 131. It should be understood that the diameter of the first conductive post may be not smaller than the diameter of the second conductive post, but the first conductive post is provided with a retracted groove. The limiting protrusion would be accepted in the retracted groove when the first conductive post is moving toward the second conductive post, and the first conductive post can abut against the second conductive post directly.
  • Also, it should be understood that the present disclosure is not limited to move the first conductive post toward the second conductive post by pressing the first conductive post. Alternatively, the second conductive post can be caused to move toward the first conductive post through the housing by pressing the housing.
  • According to some embodiments of the present disclosure, a water outlet faucet is provided. As shown in Figs. 2-5, a water inlet channel 201, a first water outlet channel 202 which is electrically controlled (hereinafter referred to as "electrical water outlet channel") and a second water outlet channel 203 which is mechanically controlled (hereinafter referred to as "mechanical water outlet channel") are formed inside the water outlet faucet.
  • It should be understood that the water outlet faucet is also provided with a top spray shower head water outlet (not shown) and a hand-held shower head water outlet (not shown) which are communicated with the top spray shower head (not shown) and the hand-held shower head (not shown), respectively. In addition, both the electrical water outlet channel 202 and the mechanical water outlet channel 203 are respectively communicated with the top spray shower head water outlet and the hand-held shower head water outlet.
  • To be specific, the water outlet faucet includes an electromagnetic valve assembly 10 provided in the electrical water outlet channel 202, a first switching valve 20 for the switch between the electrical water outlet channel 202 and the mechanical water outlet channel 203, a second switching valve 30 provided in the mechanical water outlet channel 203, the automatic reset touch mechanism 100, and a control module 200 which is electrically connected with the electromagnetic valve assembly 10 and controls ON/OFF of the electromagnetic valve assembly 10.
  • It should be noted that the control module 200 includes a first controller 210 and a second controller 220 that are electrically connected with each other as shown in Fig. 5. The first controller 210 is electrically connected to the automatic reset touch mechanism 100 for receiving and converting an electrical signal of the automatic reset touch mechanism 100 (different states of the first conductive unit and the second conductive unit correspond to different electrical signals); and the second controller 220 is electrically connected to the electromagnetic valve assembly 10 for controlling the working state of the electromagnetic valve in the electromagnetic valve assembly 10. It should be understood that both of the first controller 210 and the second controller 220 may be a Single Chip Microcomputer.
  • A plurality of electromagnetic valves (not shown) may be provided inside the electromagnetic valve assembly 10 for switching the electrical water outlet channel 202 between water coming out from the top spray shower head and water coming out from the hand-held shower head. Alternatively, the electromagnetic valve assembly 10 is provided with an electromagnetic valve at the top spray shower head water outlet and at the hand-held shower head water outlet, respectively, and the switch between water coming out from the top spray shower head and the hand-held shower head is realized by controlling ON/OFF of the electromagnetic valve.
  • As shown in Fig. 4, the first switching valve 20 and the second switching valve 30 may both be a pressing-type water diversion valve, that is, water diversion is realized by way of pressure, and both of them are provided with two water outlets.
  • As for the first switching valve 20, the water inlet of the first switching valve 20 is communicated with the water inlet channel 201, and the two water outlets of the first switching valve 20 are respectively communicated with the electrical water outlet channel 202 and the mechanical water outlet channel 203. When the first switching valve 20 is pressed, the switch between communication of the water inlet channel 201 with the electrical water outlet channel 202 and communication of the water inlet channel 201 with the mechanical water outlet channel 203 is realized by the first switching valve 20.
  • As for the second switching valve 30, the water inlet of the second switching valve 30 is communicated with the mechanical water outlet channel 203, and the two water outlets of the second switching valve 30 are respectively communicated with the top spray shower head water outlet and the hand-held shower head water outlet. When the second switching valve 30 is pressed, the switch between communication of the mechanical water outlet channel 203 with the top spray shower head water outlet and communication of the mechanical water outlet channel 203 with the hand-held shower head water outlet is realized by the second switching valve 30.
  • The first switching valve 20 is provided with a conductive switching handle 21, which abuts against and is used to press the first conductive unit 120 of the automatic reset touch mechanism 100. It should be understood that the switching handle 21 may be fabricated from electrically conductive metal materials.
  • To be specific, the switching handle 21 is formed with an extension 211 at a position of the switching handle 21 corresponding to the first conductive unit 120 of the automatic reset touch mechanism 100, and the extension 211 abuts against and is used to press the first conductive unit 120 of the automatic reset touch mechanism 100.
  • When the user presses the switching handle 21 by hand to turn on the first switching valve 20, the automatic reset touch mechanism 100 is grounded through the conductive switching handle 21; furthermore, when the first conductive unit 120 and the second conductive unit 130 of the automatic reset touch mechanism 100 are electrically conductive with each other, the automatic reset touch mechanism 100 sends an electrical signal to the first controller 210.
  • It should be understood that the water outlet faucet according to the present disclosure has two working states: an electronically controlled water outlet state and a mechanically controlled water outlet state.
  • When the water outlet faucet is in the state of electronically controlled water outlet, water enters the electrical water outlet channel 202 from the water inlet channel 201, and the switch between water coming out from the top spray shower head and water coming out from the hand-held shower head is realized by controlling the electromagnetic valve. In the electronically controlled water outlet state, the electromagnetic valve assembly 10 can be controlled by pressing keys at a key indicator light 70 shown in Fig. 2, which is an example of a display device, to realize the switch between water coming out from the top spray shower head and water coming out from the hand-held shower head.
  • It is understood that these keys can be combined with the key indicator light 70 or located beside the key indicator light 70 so that these keys are illuminated by the key indicator light 70. The key indicator light 70 can also be used to indicate the water outlet state of the top spray shower head and the water outlet state of the hand-held shower head.
  • When the water outlet faucet is in the state of mechanically controlled water outlet, water enters the mechanical water outlet channel 203 from the water inlet channel 201, and the switch between water coming out from the top spray shower head and water coming out from the hand-held shower head is realized and controlled through the pressing operation of the second switching valve 30.
  • To be specific, the process of switching the water outlet faucet from the electronically controlled water outlet state to the mechanically controlled water outlet state is as follows:
    The user presses the switching handle 21 by hand. On the one hand, the first switching valve 20 communicates the water inlet channel 201 with the mechanical water outlet channel 203, and isolates the water inlet channel 201 from the electrical water outlet channel 202, so that the water in the water inlet channel 201 enters the mechanical water outlet channel 203, and the switch between water coming out from the top spray shower head and water coming out from the hand-held shower head is realized by the pressing operation on the second switching valve 30. On the other hand, the switching handle 21 of the first switching valve 20 presses the automatic reset touch mechanism 100 and makes the first conductive unit 120 and the second conductive unit 130 of the automatic reset touch mechanism electrically conductive with each other. The first controller 210 receives an electrical signal provided by the automatic reset touch mechanism 100 and sends it to the second controller 220 which controls the electromagnetic valve in the electromagnetic valve assembly 10 to be turned off and stay in a power-off state according to the received electrical signal.
  • The process of switching the water outlet faucet from the state of mechanically controlled water outlet to the state of electronically controlled water outlet is as follows:
    The user releases the switching handle 21 (for example, to bounce up the switching handle 21 by pressing the switching handle 21). On the one hand, the first switching valve 20 communicates the water inlet channel 201 with the electrical water outlet channel 202, and isolates the water inlet channel 201 from the mechanical water outlet channel 203, so that the water in the water inlet channel 201 enters the electrical water outlet channel 202. On the other hand, the switching handle 21 of the first switching valve 20 releases the automatic reset touch mechanism 100, so that the restore of the elastic member 140 of the automatic reset touch mechanism 100 causes the first conductive unit 120 to be electrically separated from the second conductive unit 130. The first controller 210 receives the electrical signal provided by the automatic reset touch mechanism 100 and sends it to the second controller 220 which controls the electromagnetic valve in the electromagnetic valve assembly 10 to be in an energized state according to the received electrical signal, and the switch between water coming out from the top spray shower head and water coming out from the hand-held shower head is realized through ON/OFF of the electromagnetic valve in the electromagnetic valve assembly 10.
  • In the example shown in Fig. 2, the display device is a key indicator light 70 and is electrically connected to the second controller 220. For the key indicator light 70, when the first conductive unit and the second conductive unit are electrically conductive with each other, the first controller 210 receives the electrical signal provided by the automatic reset touch mechanism 100 and sends it to the second controller 220 which controls the key indicator light 70 to turn off according to the received electrical signal. For example, when the water outlet faucet is in the state of mechanically controlled water outlet, the key indicator light 70 is OFF; and when the water outlet faucet is in the state of electronically controlled water outlet, the key indicator light 70 is ON.
  • It should be understood that the display device may include two key indicator lights. When the water outlet faucet is in the state of electronically controlled water outlet, the first key indicator is OFF and the second key indicator is ON; and when the water outlet faucet is in the state of mechanically controlled water outlet, the first key indicator is ON and the second key indicator is OFF. Optionally, the display device may display the state of mechanically controlled water outlet and the state of electronically controlled water outlet respectively by displaying different colors.
  • It should be understood that the water outlet faucet may further include a thermostatic valve 40 and a hydroelectric generator 50 which are sequentially provided in the water inlet channel 201 along the water flow direction, a display screen 60 electrically connected to the hydroelectric generator 50.
  • The thermostatic valve 40 is used for adjusting the water temperature in the water inlet channel 201, and the hydroelectric generator 50 is used for generating electricity by relying on the water in the water inlet channel 201 and directly supplying electric energy to the display screen 60. The hydroelectric generator 50 may also supply electricity for the key indicator light 70, the electromagnetic valve assembly 10, the control module 200 and so forth.
  • Compared with the prior art, the technical solution of the present disclosure has the following beneficial effects:
    1. i. In the automatic reset touch mechanism, the first conductive unit is pressed to move toward the second conductive unit in the guide passage and cause the elastic member to deform, so that the first conductive unit and the second conductive unit are electrically conductive with each other, and by pressing the first conductive unit to realize the electrical conduction between the first conductive unit and the second conductive unit, the mechanical pressing action is thereby converted into an electrical signal. The automatic reset touch mechanism is simple in structure, easy to realize, applicable to a wide range of application fields, and adapted to products including but not limited to valves, faucets and the like.
    2. ii. The first conductive post passes through the bottom of the elastic member and extends into the guide passage, the first conductive post is pressed to move along the guide passage, and the elastic member is caused to deform by the first conductive post. After the pressing on the first conductive post is released, the automatic resetting function is realized through the restore of the elastic member. The structure is simple and easy to realize.
    3. iii. The open end of the elastic member is tightly sleeved on the outer surface of the housing, so that a closed space is formed between the elastic member and the housing. The open end of the guide passage is sealed by the elastic member, so that the automatic reset touch mechanism has good sealing performance and is applicable to complicated environments, such as humid environments and the like.
    4. iv. The second conductive post and the conductive spring are both accommodated in the guide passage. One end of the wire extends into the guide passage and is hermetically and fixedly connected with the housing, and the other end extends out of the guide passage and is electrically connected with an external circuit. A conductive spring is provided in the second conductive unit, so that after the first conductive unit and the second conductive post abut against each other, the pressing stroke can be further increased by the conductive spring.
    5. v. The inner surface of the guide passage is provided with a limiting protrusion for limiting the moving range of the second conductive post. The second conductive post is provided between the limiting protrusion and the conductive spring, and the limiting protrusion can prevent the second conductive post from moving freely, thereby the stability and service life of the automatic reset touch mechanism is improved.
    6. vi. In the faucet, the first switching valve is provided with a conductive switching handle which abuts against and is used to press the first conductive unit of the automatic reset touch mechanism, and the second conductive unit of the automatic reset touch mechanism is electrically connected with the control module, thus the water outlet faucet can be switched between an electronically controlled water outlet state and a mechanically controlled water outlet state, thereby the reliability and adaptability of the product is improved.
    7. vii. The switching handle is formed with an extension at a position of the switching handle corresponding to the first conductive unit of the automatic reset touch mechanism, and the extension abuts against and is used to press the first conductive unit of the automatic reset touch mechanism. Such structure is simple and stable and is easy to implement.
    8. viii. The second switching valve is used to realize the switch between water coming out from the top spray shower head and water coming out from the hand-held shower head. The switch between water coming out from the top spray shower head and water coming out from the hand-held shower head in the mechanical water outlet channel is realized through the second switching valve. Such structure is simple, stable and reliable.
    9. ix. When the first conductive unit and the second conductive unit are electrically conductive with each other, the automatic reset touch mechanism sends an electrical signal to the control module, and the control module controls the key indicator light to turn off according to the electrical signal. In particular, at this time, the faucet is in the mechanically controlled water outlet state, and by turning off the key indicator light in the mechanically controlled water outlet state, the user can be prevented from misoperation when seeing the key indicator light.
