[0036] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0037] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "horizontal", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present invention.

[0038] like Figures 1 to 5 As shown, the utility model provides an electronic faucet handle, comprising:

[0039] The fixed housing includes a receiving groove 1 with a circular notch. The receiving groove 1 is used to accommodate and fix the PCB board 3 described below. The inner cavity shape of the receiving groove 1 can be adaptively designed according to the shape of the handle. For ease of processing, the receiving groove 1 can be set as a circular groove. The notch of the receiving groove 1 needs to be designed to be circular so as to adapt to the first connecting component 6 of the screwing housing described below, so as to retain the traditional operating habit of the handle screwing operation. The fixed housing also includes a faucet connecting component 2 provided on the back of the receiving groove 1. The faucet connecting component 2 is used to connect to the housing of the faucet. For example, a mounting hole can be provided on the housing of the faucet. The faucet connecting component 2 can be embedded in the mounting hole to complete the installation. The mounting hole can be a mounting hole for installing a mechanical handle with a ceramic valve core. By providing a fixed housing that can be installed on the faucet, the faucet electronic handle described in this application has better adaptability and can be applied to traditional faucets (of course, the handle of the traditional faucet needs to be removed and a solenoid valve needs to be installed on the faucet pipe). It can also be applied to current faucets that use solenoid valves to control the opening and closing of water flow.

[0040] The PCB board 3 is fixed in the receiving groove 1, such as being fixed in the receiving groove 1 with screws. A touch switch 4 and a ring encoder 5 that is sleeved on the outside of the touch switch 4 and coaxial with the notch of the receiving groove 1 are provided on the board surface of the PCB board 3 facing the notch of the receiving groove 1. The touch switch 4 is used to control the switch state of the circuit and / or indicate the working state, so it can be used to control the switch of the faucet solenoid valve, and then control the opening and closing of the water flow. The ring encoder 5 is used to convert angular displacement into an electrical signal, so it can be used to obtain the angular displacement of the following screw shell and convert it into an electrical signal, which can be used to control the opening of the solenoid valve, thereby controlling the size of the water flow. Therefore, the present application adopts the combination of the PCB board 3, the touch switch 4 and the ring encoder 5, so that it is possible to control the opening and closing of the water flow with the touch switch 4 and to control the size of the water flow with the screw shell.

[0041] The screw housing includes a first connecting member 6 that is rotationally sealed with the notch of the receiving groove 1, and a second connecting member 7 that is connected to the rotating member of the ring encoder 5. The appearance of the screw housing can be designed based on aesthetics and ease of grip. The first connecting member 6 needs to be adapted to the notch of the receiving groove 1 to achieve the rotational sealing function, and the second connecting member 7 needs to be adapted to the rotating member of the ring encoder 5 to facilitate the connection between the two.

[0042] The screw housing is provided with a connecting rod component 8 having one end protruding into the center of the ring encoder 5 and abutting against the tact switch 4. The screw housing also includes a pressing component 9. The other end of the connecting rod component 8 is connected to the pressing component 9 to transmit the pressure exerted on the pressing component 9. The screw housing is also provided with a reset component 10 for resetting the connecting rod component 8 and the pressing component 9. Here, the pressing component 9 is used to receive the force applied by the user, and the pressing component 9 transmits the force to the connecting rod component 8, which then applies the force to the tact switch 4, thereby causing the tact switch 4 to send a corresponding signal. When the user does not apply force to the pressing component 9, the reset component 10 resets the connecting rod component 8 and the pressing component 9.

[0043] In the above embodiment, the faucet electronic handle can be used to upgrade and transform traditional faucets, and can also be adapted to current faucets with solenoid valves to control water flow, with better adaptability. At the same time, a pressing component 9 that can control the touch switch 4 is provided on the screw shell, and the pressing position on the handle is clear. When used in some scenarios where the touch switch 4 is used to control the opening and closing of the water flow, the user can quickly find the switch position, and the user experience is better. In addition, the screw shell can also be rotated, and the annular encoder 5 can convert the angular displacement into an electrical signal. The PCB board 3 can control the opening of the solenoid valve based on the electrical signal. Therefore, when used in some scenarios where the solenoid valve is used to control the water flow, the electronic handle described in this application can also retain the operating habit of rotating the traditional faucet to control the water flow.

[0044] Specifically, in an application scenario of the electronic faucet handle described in the present application, the touch switch 4 is used to control the opening and closing of the water flow, and to switch to the temperature control mode by long pressing for 3 seconds. When in the temperature control mode, the ring encoder 5 is used to convert the angular displacement of the screw shell into an electrical signal, thereby cooperating with the PCB board 3 to control the opening ratio of the hot and cold water channels of the mixing valve, thereby controlling the water temperature.

[0046] Here, the first connecting tube 601 is rotatably connected to the notch of the receiving tank 1. By adding an O-ring 602, the first connecting tube 601 and the notch of the receiving tank 1 are further sealed to prevent humid air near the faucet from entering the receiving tank 1 and affecting the normal operation of electronic equipment such as the PCB board 3, the ring encoder 5 and the touch switch 4.

[0047] In another embodiment, the first connecting component 6 further includes:

[0048] The indicator ring 603 is coaxially connected to the outside of the end of the first connecting tube 601 near the notch of the receiving tank 1. The outer diameter of the indicator ring 603 is larger than the outer diameter of the first connecting tube 601, so that the outer peripheral wall of the indicator ring 603 is exposed outside the receiving tank 1, wherein the first connecting tube 601 and the indicator ring 603 are both made of transparent material.

[0049] Here, by providing a first connecting tube 601 and an indicator ring 603 made of transparent material, if a light source is provided on the PCB board 3, a color can be displayed through the first connecting tube 601 and the indicator ring 603. The color can be used to display water temperature or other purposes, which is both beautiful and functional.

[0050] In another embodiment, a color-changing light is provided on the PCB board 3, and the first connecting tube 601 and the indicator ring 603 are used to indicate the color of the color-changing light. When the color-changing light is used in combination with the first connecting tube 601 and the indicator ring 603 in the above embodiment, it can be used to indicate water temperature or other information.

[0051] In another embodiment, the second connecting component 7 includes:

[0052] A stepped hollow shaft, wherein the outer wall of the small outer diameter shaft section of the stepped hollow shaft is provided with an external thread, and the end of the large outer diameter shaft section of the stepped hollow shaft is provided with an annular buckle;

[0053] The outer periphery of the rotating member of the annular encoder 5 is provided with an annular groove matching the annular buckle, and the large outer diameter shaft section of the stepped hollow shaft is clamped on the rotating member of the annular encoder 5;

[0054] An annular partition 604 is coaxially provided at the end of the first connecting tube 601 near the notch of the receiving tank 1. A second connecting tube 605 is coaxially provided in the central hole of the partition 604. The inner wall of the second connecting tube 605 is provided with an internal thread matching the external thread. The small outer diameter shaft section of the stepped hollow shaft is threadedly connected to the second connecting tube 605.

[0055] The connecting rod member 8 passes through the stepped hollow shaft.

[0056] One end of the stepped hollow shaft described here is clamped with the rotating part of the annular encoder 5, and the other end is threadedly connected to the second connecting tube 605, and the second connecting tube 605 is connected to the first connecting tube 601. Therefore, when the first connecting part 6 rotates, it can drive the second connecting part 7 to rotate, and then drive the rotating part of the annular encoder 5 to rotate, thereby realizing the conversion of the rotational angular displacement of the first connecting part 6 into an electrical signal.

[0057] In another embodiment, the screwing shell also includes a handle component 11, the handle component 11 is provided with a circular through hole inner cavity, the indicator ring 603 is coaxially connected to the wall surface of the accommodating groove 1 facing away from the third connecting tube 606, the outer periphery of the third connecting tube 606 is threadedly connected to one end of the circular through hole inner cavity, and the pressing component 9 is arranged at the other end of the circular through hole inner cavity.

[0058] Here, a handle component 11 is provided and threadedly connected to the third connecting tube 606. Since the third connecting tube 606 is connected to the indicator ring 603, when the handle component 11 rotates, it can drive the first connecting component 6 to rotate, thereby converting the rotational angular displacement generated by the user turning the handle component 11 into an electrical signal.

[0059] More specifically, the first connecting tube 601 , the indicator ring 603 , the partition 604 , the second connecting tube 605 and the third connecting tube 606 in the first connecting component 6 can be made of acrylic material as an integral piece, which is convenient for assembly during production.

[0060] In another embodiment, the connecting rod component 8 is movably disposed in the screw housing along the axial direction of the ring encoder 5 .

[0061] In another embodiment, a circular stepped plate 1101 is provided in the inner cavity of the circular through hole, so that the handle component 11 and the circular stepped plate 1101 form a stepped groove, the notch of the stepped groove faces the same direction as the accommodating groove 1, the small inner diameter groove section of the stepped groove extends into the third connecting tube 606, and the bottom of the small inner diameter groove section of the stepped groove and the end of the second connecting tube 605 form an annular clamping interval, and an annular sealing film 12 is clamped in the clamping interval;

[0062] A through hole is provided at the bottom center of the small inner diameter groove section of the stepped groove, and the connecting rod component 8 passes through the center hole of the annular sealing film 12 and the through hole, and a sealing structure is formed between the connecting rod component 8 and the annular sealing film 12.

[0063] Here, the outer ring of the annular sealing film 12 is clamped between the stepped groove and the second connecting tube 605, and the inner ring is sealed with the connecting rod component 8, so that a seal is formed between the handle component 11 and the second connecting tube 605, preventing the humid air near the faucet from entering the receiving groove 1 through the handle component 11 and the second connecting tube 605, affecting the normal operation of electronic equipment such as the PCB board 3, the annular encoder 5 and the touch switch 4.

[0064] In another embodiment, the pressing component 9 includes:

[0065] The pressing groove 901 has a groove opening facing the bottom of the small inner diameter groove section of the stepped groove, and the pressing groove 901 is engaged with the small inner diameter groove section of the stepped groove. The bottom of the pressing groove 901 protrudes toward the bottom of the small inner diameter groove section of the stepped groove to form a stepped hole, and the bottom of the stepped hole passes through;

[0066] The connecting rod component 8 includes: a stepped shaft, one end of the large-diameter shaft section of which abuts against the tact switch 4, and the annular surface of the other end abuts against the annular sealing film 12, the end of the small-diameter shaft section of the stepped shaft passes through the central hole of the annular sealing film 12, the through hole and the small-diameter section of the stepped hole, enters the large-diameter section of the stepped hole, and is threadedly connected with a nut to connect the small-diameter shaft section of the stepped shaft to the pressing groove 901;

[0067] The bottom of the pressing groove 901 is elastic in the axial direction of the annular encoder 5 , so that when the bottom of the pressing groove 901 is subjected to pressure, it presses against the annular sealing film 12 and then transmits the pressure to the large diameter shaft section of the stepped shaft.

[0068] Here, the small-diameter section of the stepped shaft is fixed to the large-diameter section of the stepped hole via a nut. Furthermore, since the annular surface at the other end of the large-diameter section of the stepped shaft abuts against the annular sealing film 12, tightening the nut can enhance the clamping and pressing of the annular surface at the other end of the large-diameter section of the stepped shaft against the annular sealing film 12, thereby enhancing the sealing effect. Furthermore, when the bottom of the pressing groove 901 is pressed, the pressure is transmitted to the stepped shaft. Due to the deformability of the annular sealing film 12, the connecting rod component 8 can be moved axially along the annular encoder 5, thereby applying pressure to the touch switch 4 and generating an electrical signal.

[0069] In another embodiment, the reset component 10 is a spring, which is arranged between the bottom of the small inner diameter groove section of the stepped groove and the bottom of the pressing groove 901. Here, when the bottom of the pressing groove 901 is subjected to pressure, the distance between the bottom of the pressing groove 901 and the bottom of the small inner diameter groove section of the stepped groove is reduced, and the spring contracts to accumulate elastic potential energy. When the external pressure on the pressing groove 901 disappears, the spring releases the elastic potential energy, pushing the bottom of the pressing groove 901 to reset, and the bottom of the pressing groove 901 drives the connecting rod component 8 to reset;

[0070] The pressing component 9 further includes a pressing cover plate 902, which is disposed in the large inner diameter groove section of the stepped groove and connected to the bottom of the pressing groove 901. The pressing cover plate 902 is provided on the handle component 11, which is both aesthetically pleasing and increases the pressing contact surface, making it easier to use. It also provides a certain degree of protection for the components inside the handle component 11.

[0071] The faucet connecting component 2 includes a glue filling groove 201 arranged on the back of the accommodating groove 1. The groove wall of the glue filling groove 201 is provided with a fixing hole 202 for connecting to the faucet, which can strengthen the connection between the electronic handle and the faucet. The bottom of the glue filling groove 201 is provided with a wire hole 203. Since the electronic handle is equipped with electrical components, it is necessary to reserve the wire hole 203 to connect with the external circuit. The glue filling groove 201 is used to fill the colloid to seal the wire hole 203. Here, the glue filling groove 201 can seal the wire hole 203 to prevent the humid air near the faucet from entering the fixed shell through the wire hole 203.

[0072] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented.
