The faucet body 1 is provided with a pull-out channel 10. The pull-out hose 2 movably penetrates through the pull-out channel 10. The water outlet 3 is connected with a water outlet end of the pull-out hose 2. The water outlet 3 can be a kitchen shower head or a spray gun. A water outlet end of the control box 4 is connected with a water inlet end of the pull-out hose 2. The travel switch 5 is fixedly arranged in the pull-out channel 10, and the travel switch 5 is electrically connected with the control box 4 and controls whether the control box 4 discharges water or not. The mechanical pressing mechanism 6 comprises a movable part 61, a switching part 62, and a resetting part 63 arranged in the pull-out channel 10. The switching part 62 movably sleeves the pull-out hose 2 and movably presses a button 51 of the travel switch 5. The movable part 61 is fixedly fitted with the pull-out hose 2 and movably presses the switching part 62. The resetting part 63 cooperates with the switching part 62 and is configured to drive the switching part 62 to release pressing of the button 51 of the travel switch 5.

The working principle of the electronic pull-out faucet of the present disclosure is as follows:

According to the present disclosure, when the pull-out hose 2 is in a reset state, the movable part 61 presses the switching part 62 to enable the switching part 62 to press the button 51 of the travel switch 5, and at this time, the travel switch 5 controls the control box 4 to stop water discharge, so that the water outlet 3 does not discharge water.

According to the present disclosure, when the pull-out hose 2 is in a pull-out state, the movable part 61 moves away from the switching part 62 along with the pulling out of the pull-out hose 2, so that the movable part 61 is released from pressing the switching part 62, and the switching part 62 moves under the action of the resetting part 63 to release the pressing on the button 51 of the travel switch 5, and at this time, the travel switch 5 controls the control box 4 to discharge water, so that the water outlet 3 discharges water.

It can be seen from the above description that the electronic pull-out faucet of the present disclosure can automatically discharge water when the pull-out hose 2 is pulled out, and automatically turn off the water discharge when the pull-out hose 2 is reset, which provides convenience for users to use water in the case that the pull-out hose 2 needs to be pulled out. In addition, the travel switch 5 is low in cost, contributing to a reduction in overall costs.

To further explain the technical solutions of the present disclosure, a detailed description of the present disclosure is provided hereinafter through specific embodiments.

Embodiment I

With reference to FIGS. 1 to 7, in Embodiment I of the present disclosure, the resetting part 63 of the mechanical pressing mechanism 6 is a spring structure (that is, the resetting part 63 is a spring); a first end of the resetting part 63 abuts against the switching part 62, a second end of the resetting part 63 abuts against a fixing seat 7 arranged inside the faucet body 1; the fixing seat 7 is disposed on one side of the switching part 62 distant from the movable part 61. When the movable part 61 presses the switching part 62 to enable the switching part 62 to press the button 51 of the travel switch 5, the switching part 62 drives the resetting part 63 to compress; when the movable part 61 releases the pressing on the switching part 62, the resetting part 63 expands to drive the switching part 62 to move, so that the switching part 62 releases the pressing on the button 51 of the travel switch 5. The spring-structured resetting part 63 has elasticity, and therefore the resetting part 63 also provides a buffering effect, which can reduce the impact on the switching part 62 when the movable part 61 presses the switching part 62, preventing the switching part 62 from applying excessive pressure on the button 51 of the travel switch 5, thereby protecting the travel switch 5.

In Embodiment I of the present disclosure, the travel switch 5 is obliquely arranged relative to the pull-out hose 2, and one end of the switching part 62 close to the travel switch 5 forms a pressing part 621 configured to movably press the button 51 of the travel switch 5. With such an arrangement, the pressing part 621 of the switching part 62 does not perpendicularly press the button 51 of the travel switch 5, which helps to reduce the effective impact force applied to the button 51 of the travel switch 5, thereby facilitating protection of the travel switch 5. The pressing part 621 is cylindrical, and the pressing part 621 movably sleeves the pull-out hose 2, thus ensuring that the pressing part 621 can press the button 51 of the travel switch 5. The pressing part 621 of the switching part 62 may have a pressing inclined surface 6211 that tapers toward the pull-out hose 2 along the direction from the switching part 62 to the travel switch 5, the pressing inclined surface 6211 movably presses the button 51 of the travel switch 5; the pressing inclined surface 6211 also helps to reduce the effective impact force applied to the button 51 of the travel switch 5, thereby facilitating protection of the travel switch 5.

In Embodiment I of the present disclosure, the faucet body 1 comprises a faucet bent pipe 11 and a faucet main body 12 connected to each other, and the pull-out channel 10 is formed inside the faucet bent pipe 11 and the faucet main body 12; the faucet bent pipe 11 and the faucet main body 12 are rotatably connected, allowing the faucet bent pipe 11 to rotate relative to the faucet main body 12, so that the water discharge direction of the water outlet 3 can be changed by rotating the faucet bent pipe 11 when the pull-out hose 2 is in the reset state. The travel switch 5 is arranged in the faucet main body 12 to prevent the travel switch 5 from interfering with the rotation of the faucet bent pipe 11.

In Embodiment I of the present disclosure, the control box 4 comprises a box body 41, and a control circuit board 42 and a solenoid valve 43 arranged inside the box body 41. A water inlet end of the solenoid valve 43 serves as the water inlet end of the control box 4, and a water outlet end of the solenoid valve 43 serves as the water outlet end of the control box 4. The control circuit board 42 is electrically connected to both the travel switch 5 and the solenoid valve 43; the control circuit board 42 controls the opening and closing of the solenoid valve 43 based on the signal of the travel switch 5, thereby regulating whether the control box 4 discharges water or not.

In Embodiment I of the present disclosure, the pull-out hose 2 is provided with a counter weight 21, and the counter weight 21 can drive the pull-out hose 2 to reset. Meanwhile, when the pull-out hose 2 is in the reset state, the counter weight 21 allows the movable part 61 to reliably press the switching part 62, so that the switching part 62 can reliably press the button 51 of the travel switch 5.

In Embodiment I of the present disclosure, the electronic pull-out faucet of the present disclosure further comprises an infrared sensor 8 installed on the faucet body 1. The infrared sensor 8 is specifically arranged on the faucet main body 12 of the faucet body 1, and the infrared sensor 8 is electrically connected to the control circuit board 42. When the pull-out hose 2 is in the reset state, induction control over the control circuit board 42 can be performed through the infrared sensor 8, which in turn controls the opening and closing of the solenoid valve 43 to regulate whether the water outlet 3 discharges water or not, so that the induction-based water discharge control function is realized, providing convenience for users.

In Embodiment I of the present disclosure, the infrared sensor 8 and the travel switch 5 are electrically connected to the control circuit board 42 through a connecting cable 9, and a battery for supplying power to the control circuit board 42, the solenoid valve 43, the infrared sensor 8 and the travel switch 5 may be arranged inside the control box 4.

In Embodiment I of the present disclosure, the electronic pull-out faucet of the present disclosure further comprises a mechanical temperature adjusting valve 13 installed on the faucet body 1. The mechanical temperature adjusting valve 13 is specifically installed on the faucet main body 12 of the faucet body 1. A water outlet end of the mechanical temperature adjusting valve 13 is connected to the water inlet end of the control box 4; the mechanical temperature adjusting valve 13 can adjust the water discharge temperature of the water outlet 3, and meanwhile, the mechanical temperature adjusting valve 13 can also realize the function of a main valve; the mechanical temperature adjusting valve 13 may be a single-handle double-control temperature adjusting valve.

Embodiment II

With reference to FIGS. 8 to 11, Embodiment II of the present disclosure differs from Embodiment I in the configuration of the resetting part 63.

Specifically, in Embodiment II of the present disclosure, the resetting part 63 comprises at least one fixed magnet 631 which is fixedly provided in the faucet body 1, and the fixed magnet 631 may fit in the fixing seat 7 arranged inside the faucet body 1. At least one movable magnet 622 is correspondingly provided in the switching part 62, and each of the fixed magnets 631 magnetically repels each of the movable magnets 622. When the movable part 61 presses the switching part 62 to enable the switching part 62 to press the button 51 of the travel switch 5, the switching part 62 overcomes the repulsive force between each of the movable magnets 622 and each of the fixed magnets 631 under the pressing of the movable part 61, driving each of the movable magnets 622 and each of the fixed magnets 631 to move towards each other. When the movable part 61 releases the pressing on the switching part 62, the repulsive force between each of the movable magnets 622 and each of the fixed magnets 631 drives the switching part 62 to move, so that the switching part 62 releases the pressing on the button 51 of the travel switch 5. It should be noted that the repulsive forces between each of the movable magnets 622 and each of the fixed magnets 631 can reduce the impact on the switching part 62 when the movable part 61 presses the switching part 62, preventing the switching part 62 from applying excessive pressure on the button 51 of the travel switch 5, thereby protecting the travel switch 5.

The above embodiments and illustrations are not intended to limit the form and style of the product of the present disclosure, any appropriate variations or modifications made by those of ordinary skills in the art shall be considered as falling within the scope of the patent of the present disclosure.
