[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0030] The present invention realizes the lifting and lowering control of the shower rod by setting a power source 30 to control the driving member, and the control unit can control the power source 30 to automatically stop when the upper rod body 10 moves to a preset position, thereby preventing power consumption and protecting the power source, extending the service life, having a simple structure and being easy to operate.

[0031] like Figures 1 to 5 As shown: This embodiment discloses an electric lifting shower rod, comprising:

[0032] The upper rod body 10 is provided with a nozzle 11 and a first threaded portion 12;

[0033] The lower rod body 20 has a water supply channel for supplying water to the spray head 11 and is provided with a second threaded portion 21 that matches the first threaded portion 12;

[0034] A driving member, driving the first threaded portion 12 or the second threaded portion 21 to rotate, thereby controlling the lifting and lowering of the upper rod body 10;

[0035] A power source 30, providing power to the driving member;

[0036] The control unit includes a detection module. When the detection module detects that the upper rod body 10 moves to a preset position, the control unit controls the power source 30 to be turned off.

[0037] The preset positions of this embodiment include the upper rod body 10 moving relative to the lower rod body 20 to an upper limit position and a lower limit position.

[0038] In this embodiment, a second sensing element for detecting the movable stroke or rotation angle of the driving element is further included. The position of the upper rod body 10 is determined by detecting the movable stroke or rotation angle of the driving element. There is no need to set up in-position detection mechanisms at both ends of the upper rod body 10, thereby saving product space.

[0039] In this embodiment, the driving member includes a transmission-coordinated reduction gear 40a and an output gear 40b, wherein the power source 30 is transmission-coordinated with the reduction gear 40a, and the output gear 40b is transmission-coordinated with the first threaded portion 12 or the second threaded portion 21. Specifically, the power source 30 adopts a motor 30, and the motor 30 is provided with a driving gear 31 transmission-coordinated with the reduction gear 40a. In this embodiment, the second sensing member includes a signal transmitting end 50a mounted on the reduction gear 40a, and the signal transmitting end 50a is a magnet in this embodiment, and also includes a signal receiving end 50b provided on the detection module, and the signal receiving end 50b is a Hall switch in this embodiment. Specifically, when the magnet passes the Hall switch, the Hall switch turns off the motor 30, stops the motor, and waits for the next lifting operation. The Hall switch and the magnet are relatively common signal switches, which are low in cost and resistant to water and moisture.

[0040] In other embodiments, when the detection module detects that the first threaded portion 12 or the second threaded portion 21 is stuck, the upper rod body 10 moves to the preset position accordingly. In this embodiment, the detection module includes a current detector, and the current detector is used to detect the circuit current of the power source 30. When the current detector detects that the circuit current of the power source 30 has a sudden change, it is determined that the first threaded portion 12 or the second threaded portion 21 is stuck. Of course, in other embodiments, it is also possible to detect that the first threaded portion 12 or the second threaded portion 21 has not produced a height change within a preset time, thereby determining that the first threaded portion 12 or the second threaded portion 21 is stuck. Specifically, during the lifting and lowering process of the upper rod body 10, it is detected whether the current suddenly rises. If the current suddenly rises, the power source 30 is turned off.

[0041] In this embodiment, the first threaded portion 12 is fixedly disposed on the upper rod body 10, and the second threaded portion 21 is circumferentially rotatable and axially limited on the lower rod body 20. Since the lower rod body 20 is fixedly disposed, during adjustment, the lower rod body 20 remains stationary and the second threaded portion 20 can be rotated and adjusted.

[0042] In this embodiment, one of the first threaded portion 12 and the second threaded portion 21 is a screw rod, and the other is a screw hole 12. Specifically, the first threaded portion 12 adopts the screw hole 12, and the second threaded portion 21 adopts the screw rod 21. By setting the second threaded portion 21 as the screw rod 21, the adjustment stroke can be extended and the adjustment range of the upper rod body 10 can be expanded.

[0043] In this embodiment, the lower rod body 20 includes an inlet pipe 20a and an outlet pipe 20b, which are connected to form the water supply channel. The upper rod body 10 is connected to the outlet pipe 20b and is telescopically matched, with a simple structure and easy installation.

[0044] In this embodiment, it also includes a mechanism box 60 arranged between the water inlet pipe 20a and the water outlet pipe 20b, the driving member is installed in the mechanism box 60, the mechanism box 60 is provided with an upper plug hole 611 and a lower plug hole 621, the water inlet pipe 20a is sealed and fixedly plugged with the lower plug hole 621, and the water outlet pipe 20b is sealed and fixedly plugged with the upper plug hole 611. Specifically, the mechanism box 60 includes a box body 62 and an upper cover 61, the box body 62 and the upper cover 61 are sealed and fixedly connected to form an accommodating cavity, the reduction gear 40a and the output gear 40b are both installed in the accommodating cavity, and the output gear 40b is provided with a limiting hole 41, and the screw rod is provided with a mounting portion 211 circumferentially limitedly connected to the limiting hole 41, the structure is more compact and the integrity is better.

[0045] The specific working process of this embodiment is as follows:

[0046] like Figures 3 to 5 As shown, during adjustment, the control unit controls the motor 30 to turn on, and the driving gear 31 of the motor 30 drives the output gear 40b to rotate through the reduction gear 40a, and the output gear 40b drives the screw rod to rotate synchronously, so that the upper rod body 10 moves up and down through the screw hole 12 and the threaded cooperation of the screw rod 21, and the output gear 40b drives the screw rod 21 to rotate forward, and then the screw hole 12 and the threaded cooperation of the screw rod 21 control the upper rod body 10 to rise; the output gear 40b drives the screw rod to reverse, and then the screw hole 12 and the threaded cooperation of the screw rod 21 control the upper rod body 10 to descend, thereby realizing the lifting and lowering adjustment of the upper rod body 10, and when the upper rod body 10 moves to a suitable position, the control unit can control the motor 30 to turn off.

[0047] This solution realizes the lifting and lowering control of the shower rod by setting a power source 30 to control the driving member, and the control unit can control the power source 30 to automatically stop when the upper rod body 10 moves to a preset position, thereby preventing power consumption and protecting the power source 30, extending the service life, having a simple structure and being easy to operate.

[0048] In other embodiments, a sensing point is provided on the output gear 40b, and a sensing head is provided on the mechanism box 60. By sensing the position of the output gear 40b or the number of revolutions, the position of the upper rod body 10 is calculated to control the upper and lower limits of the activity of the upper rod body 10.

[0049] In other embodiments, the upper rod body 10 is provided with a first sensing element, and the detection module receives a position signal emitted by the first sensing element, and then determines the position of the upper rod body 10 through the position signal. Specifically, the first sensing element can sense the height difference between the upper rod body 10 and the ground, and then determine the position of the upper rod body 10.
