DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0019] Please refer to the drawings in the embodiments of the utility model Figures 1-4 The utility model provides an electronic temperature adjusting structure of shower, including motor 1, piston 7, mixed water valve body 8. The piston 7 is nested in the movable cavity 803 of mixed water valve body 8 and can move along the axial direction in mixed water valve body 8. The motor 1 adopts linear motion motor, and the motor has the characteristics of low voltage and low power, and can directly use micro hydroelectric generator or battery to provide energy for the motor 1. One end of the piston 7 is connected to the transmission mechanism for driving the piston 7 to move linearly. The sealing cover 4 is arranged between the motor 1 and the mixed water valve body 8 to realize detachable connection of the motor 1 and the mixed water valve body 8, facilitating installation, maintenance and replacement.

[0020] The mixed water valve body 8 is provided with a plurality of cavities, and the mixed water valve body 8 is provided with cold water inlet 801, hot water inlet 802, mixed water cavity 804 and grid water outlet 805. The cold water inlet 801 is used for connecting the cold water pipeline, the hot water inlet 802 is used for connecting the hot water pipeline, and the mixed water cavity 804 is used for outputting the mixed water temperature. The cold water or hot water is adjusted to enter different cavities by the movement of the piston 7, and is mixed in the mixed water valve body 8, and finally flows out from the mixed water cavity 804 through the grid water outlet 805.

[0021] A temperature sensing probe 9 is arranged at the water mixing cavity 804 to detect the water temperature in real time. The temperature sensing probe 9 is electrically connected to the control system and feeds back the detected temperature signal to the control system. The control system adjusts the rotation direction and stroke of the motor 1 according to the target temperature set by the user and the actual temperature fed back by the temperature sensing probe 9, thereby controlling the position of the piston 7 to accurately adjust the mixing ratio of cold and hot water and ensure that the water temperature is stable at the set value.

[0022] A waterproof sealing ring can be arranged between the sealing cover 4 and the water mixing valve body 8 to prevent water from flowing into the motor 1 and ensure the safe operation of the electronic components.

[0023] The electronic temperature adjusting structure automatically adjusts the mixing ratio of cold and hot water by driving the piston 7 with the motor 1 and quickly and accurately controls the water temperature through the real-time feedback of the temperature sensing probe 9, thereby improving the shower experience. Meanwhile, the modular design facilitates installation and maintenance, and has high practicability and reliability.

[0024] One end of the sealing cover 4 is provided with a mounting portion 401 which is a cylindrical structure with an outer diameter matching the inner diameter of the movable cavity 803 of the water mixing valve body 8, so that the mounting portion 401 can be tightly nested in the movable cavity 803. Two second sealing rings 5 are arranged on the outer side of the mounting portion 401, one on the upper end and the other on the lower end, to enhance the sealing performance between the sealing cover 4 and the water mixing valve body 8 and prevent water or steam from flowing out of the water mixing valve body 8 and causing overall leakage. The motor 1 and the sealing cover 4 are connected in sequence by the screws 3 which are matched with the screw holes on the water mixing valve body 8. The penetration connection of the screws 3 not only facilitates the installation and removal of the motor 1 and the sealing cover 4, but also improves the stability and reliability of the overall structure. The matching design of the mounting portion 401 and the movable cavity 803 enables the sealing cover 4 to be accurately positioned, avoiding deviation or misplacement during installation. Through the above design, the sealing cover 4 not only realizes efficient connection between the motor 1 and the water mixing valve body 8, but also significantly improves the sealing performance and installation convenience of the overall structure, which is suitable for the electronic temperature adjusting system of the shower with high frequency of use.

[0025] A first sealing ring 2 is arranged in the mounting portion 401, with an inner diameter matching the outer diameter of the output shaft of the motor 1 and an outer diameter matching the inner wall of the mounting portion 401. When the motor 1 is installed in the mounting portion 401, the output shaft of the motor 1 presses the first sealing ring 2, thereby forming a tight sealing interface between the motor 1 and the mounting portion 401, effectively preventing water or steam from entering the motor 1 and ensuring the long-term stable operation of the motor 1.

[0026] The piston 7 comprises a shaft body 704, a first shaft ring 708 and a second shaft ring 709, wherein the second shaft ring 709 is located at the end of the piston 7, and the first shaft ring 708 is provided with a pressure relief hole 701 between the other end away from the second shaft ring 709. The pressure relief hole 701 is used to balance the pressure between the hot water pressure holding chamber 706 and the cold water pressure holding chamber 707, preventing the piston 7 from moving smoothly due to uneven pressure. The piston 7 is provided with a connecting hole 702 at the end close to the first shaft ring 708, and the middle part between the first shaft ring 708 and the second shaft ring 709 is provided with a third shaft ring 710. The telescopic shaft of the motor 1 passes through the connecting hole 702 and is locked and fixed with the nut 6 in the mounting hole 703 to connect the piston 7, wherein the inner diameter of the mounting hole 703 matches the outer diameter of the nut 6, ensuring that the nut 6 can be firmly fixed on the piston 7 to prevent loosening. The telescopic shaft of the motor 1 and the connecting hole 702 have a gap, and the nut 6 is nested in the mounting hole 703 of the piston 7 with a gap at the end face, ensuring that when there is a coaxiality deviation between the piston 7 and the telescopic shaft of the motor 1 during movement, there is a movable correction space, so that the piston 7 moves smoothly without jamming. The first shaft ring 708 and the second shaft ring 709 are circular, and part of them are respectively matched with a second sealing ring 5. The second sealing ring 5 is used to enhance the sealing performance between the piston 7 and the inner wall of the mixed water valve body 8, preventing cold and hot water from mixing during movement.

[0027] The movable cavity 803 in the mixed water valve body 8 is penetrated by the cold water inlet 801, the hot water inlet 802 and the mixed water cavity 804. The piston 7 divides the movable cavity 803 into four cavities: the hot water pressure holding chamber 706 close to the second shaft ring 709, the cold water pressure holding chamber 707 close to the first shaft ring 708, the hot water cavity 711 between the second shaft ring 709 and the third shaft ring 710, and the cold water cavity 705 between the first shaft ring 708 and the third shaft ring 710. The hot water pressure holding chamber 706 and the cold water pressure holding chamber 707 are communicated through the pressure relief hole 701 of the piston 7. During the movement of the piston 7 in the movable cavity 803, the hot water pressure holding chamber 706 and the cold water pressure holding chamber 707 form an integrated cavity, the volume of which remains unchanged, and the internal pressure remains balanced, so that the piston 7 moves smoothly without pressure holding resistance. The third shaft ring 710 and the grid water outlet 805 function to separate cold and hot water, so that the pressure difference ratio of cold and hot water is increased to 2:1, which can be applied to more than 95% of residential water pressure environment.

[0028] The specific working process of the new type is as follows: when the piston 7 moves to the leftmost end of the movable cavity 803 (close to the motor 1), at this time, the volume of the cold water pressure holding chamber 707 is the smallest, the volume of the hot water pressure holding chamber 706 is the largest, the hot water flow of the hot water inlet 802 is completely blocked, the cold water inlet 801 completely enters the cold water cavity 705, and the hot water inlet 802 is blocked. Therefore, the mixed water cavity 804 flows out of the full cold water, which is suitable for scenes requiring low temperature water flow.

[0029] When the piston 7 moves to the right end of the active cavity 803 (away from the motor 1), at this time, the volume of the hot water pressure holding cavity 706 is the smallest, the volume of the cold water pressure holding cavity 707 is the largest, the cold water flow of the cold water inlet 801 is completely blocked, and the hot water inlet 802 completely enters the hot water cavity 711, so that the mixed water cavity 804 flows out of full hot water, which is suitable for scenes requiring high temperature water flow.

[0030] When the piston 7 is between the extreme left and the extreme right state, the volume of the cold water pressure holding cavity 707 gradually decreases, and the volume of the hot water pressure holding cavity 706 gradually increases; or the volume of the cold water pressure holding cavity 707 gradually decreases, and the volume of the hot water pressure holding cavity 706 gradually increases, so that the cold water flow of the cold water inlet 801 gradually increases, and the hot water flow of the hot water inlet 802 gradually decreases; or the cold water flow of the cold water inlet 801 gradually decreases, and the hot water flow of the hot water inlet 802 gradually increases. The motor 1 can accurately control the mixing ratio of cold and hot water by adjusting the position of the piston 7, so as to realize continuous adjustment of the outlet water temperature and meet the needs of users for different water temperatures. Cold and hot water realizes pressure balance through the pressure relief hole 701, and cold and hot water is fully mixed in the mixed water cavity 804, which mainly avoids immediate uneven mixing of the cold and hot cavities, and can be more quickly and uniformly mixed after being cut off through the grid outlet 805, and can adapt to a higher cold and hot water pressure difference ratio.

[0031] In the above mixing process, the temperature probe 9 detects the water temperature of the mixed water cavity 804 in real time, and feeds back the temperature signal to the control system. The control system automatically adjusts the moving direction and stroke of the motor 1 according to the target temperature set by the user, drives the piston 7 to move to the appropriate position, and ensures that the outlet water temperature is stable at the set value. Through this intelligent adjustment mechanism, users can obtain constant comfortable water temperature without manual operation, which improves the shower experience.

[0032] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be realized in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and therefore all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims involved.
