In addition, the cost of the travel switch 5 is low, which helps to reduce the overall cost.

[0045] In order to further explain the technical solution of the present utility model, the present utility model will be elaborated in detail below through specific embodiments.

[0046] Embodiment 1:

[0047] Cooperate Figures 1 to 7As shown, in the first embodiment of the present utility model, the reset member 63 of the mechanical pressing mechanism 6 is a spring structure (i.e., the reset member 63 is a spring). One end of the reset member 63 abuts against the switch member 62, and the other end of the reset member 63 abuts against a fixed seat 7 provided inside the faucet body 1. The fixed seat 7 is located on the side of the switch member 62 away from the movable member 61. When the movable member 61 presses the switch member 62 such that the switch member 62 presses the button 51 of the travel switch 5, the switch member 62 drives the reset member 63 to compress; when the movable member 61 releases the pressure on the switch member 62, the reset member 63 expands and contracts to drive the switch member 62 to move, so that the switch member 62 releases the pressure on the button 51 of the travel switch 5. The reset member 63 of the spring structure has elasticity, so the reset member 63 also has a buffering effect and can buffer the switch member 62 when the movable member 61 presses the switch member 62, thereby preventing the switch member 62 from applying excessive pressing force on the button 51 of the travel switch 5 and protecting the travel switch 5.

[0048] In the first embodiment of the present utility model, the travel switch 5 is inclined relative to the draw hose 2. One end of the switch member 62 close to the travel switch 5 forms a pressing portion 621 for actively pressing the button 51 of the travel switch 5. Such a setting makes the pressing portion 621 of the switch member 62 not vertically press the button 51 of the travel switch 5, which helps to reduce the effective impact force received by the button 51 of the travel switch 5 and helps to protect the travel switch 5. Among them, the pressing portion 621 is in a cylindrical shape, and the pressing portion 621 is movably sleeved on the draw hose 2, so as to ensure that the pressing portion 621 can press the button 51 of the travel switch 5. The pressing portion 621 of the switch member 62 may have a pressing inclined surface 6211 that tapers toward the draw hose 2 in the direction from the switch member 62 to the travel switch 5. The pressing inclined surface 6211 actively presses the button 51 of the travel switch 5, and the pressing inclined surface 6211 also helps to reduce the effective impact force received by the button 51 of the travel switch 5 and helps to protect the travel switch 5.

A draw channel 10 is formed between the faucet elbow 11 and the faucet main body 12. The faucet elbow 11 and the faucet main body 12 are rotatably connected, so that the faucet elbow 11 can rotate relative to the faucet main body 12, so that the water outlet direction of the water outlet head 3 can be changed by rotating the faucet elbow 11 when the draw hose 2 is in the reset state. The travel switch 5 is arranged in the faucet main body 12 to avoid the travel switch 5 interfering with the rotation of the faucet elbow 11.

[0050] In the first embodiment of the present utility model, the control box 4 includes a box body 41, a control circuit board 42 and a solenoid valve 43 arranged in the box body 41. The water inlet end of the solenoid valve 43 is the water inlet end of the control box 4, and the water outlet end of the solenoid valve 43 is the water outlet end of the control box 4. The control circuit board 42 is electrically connected to the travel switch 5 and the solenoid valve 43. The control circuit board 42 controls the on-off of the solenoid valve 43 according to the signal of the travel switch 5, and further controls whether the control box 4 discharges water.

[0051] In the first embodiment of the present utility model, the draw hose 2 is provided with a weight 21. The weight 21 can drive the draw hose 2 to reset. At the same time, when the draw hose 2 is in the reset state, the movable part 61 can reliably press the switch part 62 so that the switch part 62 can reliably press the button 51 of the travel switch 5.

[0052] In the first embodiment of the present utility model, the electronic draw faucet of the present utility model further includes 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. The infrared sensor 8 is electrically connected to the control circuit board 42. When the draw hose 2 is in the reset state, people can use the infrared sensor 8 to sense and control the control circuit board 42 at this time, and then control the on-off of the solenoid valve 43 to control whether the water outlet 3 discharges water, so as to realize the induction water discharge control function and facilitate people's use.

[0053] In the first embodiment of the present utility model, the infrared sensor 8 and the travel switch 5 are electrically connected to the control circuit board 42 through a connection cable 9 together. A battery for supplying power to the control circuit board 42, the solenoid valve 43, the infrared sensor 8 and the travel switch 5 can be arranged in the control box 4.

[0054] In the first embodiment of the present utility model, in the first embodiment of the present utility model, the electronic draw faucet of the present utility model further includes a mechanical temperature regulating valve 13 installed on the faucet body 1. The mechanical temperature regulating valve 13 is specifically installed on the faucet main body 12 of the faucet body 1.

The mechanical temperature regulating valve 13 can adjust the water outlet temperature of the water outlet 3, and at the same time, the mechanical temperature regulating valve 13 can also realize the function of a main valve; the mechanical temperature regulating valve 13 can specifically adopt a single-handle double-control temperature regulating valve.

[0055] Embodiment Two:

[0056] Cooperate Figures 8 to 11 As shown, the difference between the second embodiment and the first embodiment of the present utility model lies in the setting of the reset member 63.

[0057] Specifically, in the second embodiment of the present utility model, the reset member 63 includes at least one fixed magnet 631 fixedly fitted in the faucet body 1, and the fixed magnet 631 can be fitted in the fixed seat 7 provided inside the faucet body 1; and the switch member 62 is correspondingly fitted with at least one movable magnet 622; each of the fixed magnets 631 and each of the movable magnets 622 are magnetically repulsive. When the movable member 61 presses the switch member 62 to cause the switch member 62 to press the button 51 of the travel switch 5, the switch member 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 member 61, driving each of the movable magnets 622 and each of the fixed magnets 631 to approach each other; and when the movable member 61 releases the pressing of the switch member 62, the switch member 62 is driven to move under the action of the repulsive force between each of the movable magnets 622 and each of the fixed magnets 631, so that the switch member 62 releases the pressing of the button 51 of the travel switch 5. It should be noted that the repulsive force between each of the movable magnets 622 and each of the fixed magnets 631 can play a buffering role on the switch member 62 when the movable member 61 presses the switch member 62, thereby preventing the pressing force of the switch member 62 on the button 51 of the travel switch 5 from being too large, and protecting the travel switch 5.

[0058] The above embodiments and drawings do not limit the product form and style of the present utility model. Any appropriate changes or modifications made by those of ordinary skill in the technical field to which it belongs shall be regarded as not departing from the patent scope of the present utility model.
