[0003] Traditional water temperature regulating valves have a relatively complex internal structure for controlling the ratio of hot and cold water flow, making assembly relatively difficult and hindering the improvement of assembly efficiency and the stability of the valve's operation.

[0004] Therefore, further improvements are needed. Utility Model Content

[0006] The purpose of this utility model is achieved as follows:

[0007] A commercial water temperature regulating valve includes a valve body, which has a mixing chamber and a first inlet, a second inlet, and an outlet respectively connected to the mixing chamber. A valve core is connected inside the mixing chamber and can adjust the water intake of the first inlet and the second inlet by rotating.

[0021] Figure 3 This is an exploded view of an embodiment of the present utility model. Figure 2 . Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See Figures 1-3 This commercial water temperature regulating valve includes a valve body 1, which has a mixing chamber 13 and a first inlet 11, a second inlet 12 and an outlet 14 respectively connected to the mixing chamber 13. A valve core 2 is connected inside the mixing chamber 13 and can adjust the water intake of the first inlet 11 and the second inlet 12 respectively by rotating.

[0024] The first inlet 11 and the second inlet 12 can be used to connect to the cold water supply source and the hot water supply source, respectively. After the cold water and hot water enter the mixing chamber 13 through the first inlet 11 and the second inlet 12, they can be mixed to obtain water ice of different temperatures, which is discharged from the outlet 14.

[0025] The valve body 1 is provided with a drive device 3 on the outside that can drive the valve core 2 to rotate. The drive device 3 is installed and connected to the upper outer side of the valve body 1. The valve core 2 can adjust and control the water intake of the first inlet 11 and the second inlet 12 through simple rotation, thereby simplifying the overall structural layout of the water temperature regulating valve and simplifying the installation difficulty of the product. At the same time, the transmission structure between the valve core 2 and the drive device 3 is relatively simple, which can improve the stability of the water temperature regulating valve.

[0026] Furthermore, the drive device 3 is a stepper motor, which is connected to a transmission gear 4 for linkage with the valve core 2. A control switch 5 is provided on the outer side of the transmission gear 4. The control switch 5 is electrically connected to the stepper motor. Several protruding teeth 41 that can trigger the control switch 5 are distributed on the outer side of the transmission gear 4. The spacing between adjacent protruding teeth 41 is equal. The stepper motor can make the valve core 2 rotate according to a preset rotation angle through the transmission gear 4, thereby improving the accuracy of water flow control and thus improving the accuracy of temperature control. The control switch 5 allows the user to conveniently control the rotation amplitude of the transmission gear 4.

[0027] Furthermore, a motor mounting post 15 is provided on the upper side of the valve body 1. The motor mounting post 15 protrudes upward, and the stepper motor abuts against the motor mounting post 15 and is fixed by locking components. A switch mounting post 16 is provided on the upper side of the valve body 1. The switch mounting post 16 protrudes upward, and the control switch 5 abuts against the switch mounting post 16 and is fixed by locking components. This allows a certain distance to be formed between the stepper motor and the control switch 5 and the valve body 1, reducing the chance of the stepper motor and the control switch 5 being affected by water accumulation.

[0028] Furthermore, a drive shaft 23 is provided at the center of the valve core 2. The drive shaft 23 extends upward to the outside of the valve body 1 and is driven by the drive device 3. A first sealing ring 61 is provided on the drive shaft 23 at the position corresponding to the mixing chamber 13. The first sealing ring 61 is tightly fitted with the upper side of the drive shaft 23 and the valve body 1 respectively. The connection position between the drive shaft 23 and the drive device 3 is located outside the valve body 1. The liquid in the mixing chamber 13 will not have an adverse effect on the connection position between the two. At the same time, under the action of the first sealing ring 61, the liquid in the mixing chamber 13 is not easy to leak outward, thus improving the stability of the equipment operation.

[0029] Furthermore, a positioning protrusion 131 is provided at the bottom center of the mixing chamber 13, and a positioning slot 231 corresponding to the positioning protrusion 131 is provided at the bottom of the transmission shaft 23. The positioning protrusion 131 and the positioning slot 231 are inserted into each other and slide together, so that the valve core 2 has good stability during its rotation.

[0030] Furthermore, the valve body 1 includes a base 17 and a face cover 18. The base 17 and the face cover 18 are detachable from each other. The base 17 and the face cover 18 are connected and fixed by a locking device, so that the valve core 2 can be quickly disassembled and assembled with the valve body 1.

[0031] Furthermore, the base 17 has several lower mounting ears 171 distributed circumferentially, and the cover 18 has upper mounting ears 181 corresponding to the lower mounting ears 171. The locking device includes screw devices that are respectively connected to the upper mounting ears 181 and the lower mounting ears 171, so that the cover 18 and the base 17 have good connection strength at different positions.

[0032] Furthermore, a second sealing ring 62 is provided on the side of the connection between the base 17 and the cover 18 facing the mixing chamber 13. The second sealing ring 62 is tightly fitted with the base 17 and the cover 18 respectively, improving the sealing performance of the connection between the base 17 and the cover 18, making it difficult for the liquid in the mixing chamber 13 to leak out.

[0033] Furthermore, the side wall of the valve core 2 is provided with a first regulating water hole 21 and a second regulating water hole 22 for allowing the liquid flowing through the first inlet 11 and the second inlet 12 to flow into the mixing chamber 13. The width of the first regulating water hole 21 decreases along the positive rotation direction of the valve core 2, and the width of the second regulating water hole 22 increases along the positive rotation direction of the valve core 2. When it is necessary to increase the water temperature, the valve core 2 can be rotated in the forward direction to reduce the amount of cold water entering the mixing chamber 13 through the first regulating water hole 21 and increase the amount of hot water entering the mixing chamber 13 through the second regulating water hole 22. Similarly, when it is necessary to decrease the water temperature, the valve core 2 can be rotated in the reverse direction.

[0034] Furthermore, the first regulating water hole 21 and the second regulating water hole 22 are radially mirror-symmetrical along the valve core 2, so that the increase or decrease in water volume through the first regulating water hole 21 and the second regulating water hole 22 can cancel each other out, thereby keeping the overall water inflow relatively stable.

[0035] The first regulating water hole 21 and the second regulating water hole 22 are respectively provided with a first water blocking part 241 and a second water blocking part 242 to block the liquid from the first water inlet 11 and the second water inlet 12 from flowing into the mixing chamber 13. The first water blocking part 241 and the second water blocking part 242 are respectively arranged on both sides along the radial direction of the valve core 2. The first water inlet 11 and the second water inlet 12 are respectively arranged on both sides along the radial direction of the valve body 1. The first water blocking part 241 and the second water blocking part 242 work together to achieve the effect of stopping the water supply to the mixing chamber 13.

[0036] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
