Description

Technical Field

[0001] The utility model relates to the technical field of water mixing valves, in particular to a temperature regulating valve. Background Art

[0002] A thermostatic mixing valve is a device that can mix hot and cold water and adjust the outlet water temperature, and can be used in water dispensers.

[0003] Thermostatic mixing valves usually control the on-and-off of water channels by means of valve plates cooperating with each other. For example, the patent document with publication number CN113551067A discloses a mixing valve with flow and temperature regulation functions, specifically including a mixing valve with water temperature and flow regulation functions, including a fixed valve plate, a first movable valve plate and a second movable valve plate, wherein: the first movable valve plate is abutted against the fixed valve plate in a manner that can pivot around a pivot axis, the second movable valve plate is abutted against the first movable valve plate in a manner that can pivot around the pivot axis, the fixed valve plate has a first surface abutting against the first movable valve plate, the first movable valve plate has a second surface abutting against the fixed valve plate and a third surface abutting against the second movable valve plate, the second movable valve plate has a fourth surface abutting against the first movable valve plate, a first cold water hole, a first hot water hole and a first mixing water hole extending to the first surface are provided through the fixed valve plate, a second mixing water hole and a third mixing water hole extending from the second surface to the third surface are provided through the first movable valve plate, and a mixing water groove recessed inward from the fourth surface is provided on the second movable plate.

[0004] The flow rate of the mixing valve is affected by the size of the water holes on the valve plate. When the mixing valve requires a larger flow rate, the width of the valve plate and the water holes thereon also needs to be increased, causing the overall width of the mixing valve to become correspondingly larger, increasing the difficulty of installing the mixing valve as a whole. Moreover, the material of the valve plate is usually ceramic, resulting in a relatively high production cost of the mixing valve.

[0005] Therefore, further improvements are needed. Utility Model Content

[0029] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0030] See also Figure 1-Figure 6 The thermostatic valve comprises a valve body 1 and a valve core 2. The valve core 2 is provided with a transfer chamber 23, a first thermostatic groove 21, a second thermostatic groove 22 and a thermostatic chamber 24. The transfer chamber 23 and the thermostatic chamber 24 are separated from each other. The first thermostatic groove 21 and the second thermostatic groove 22 are respectively connected with the thermostatic chamber 24. The transfer chamber 23 and the first thermostatic groove 21 and the second thermostatic groove 22 are staggered with each other. The valve body 1 is provided with a first water inlet 11, a second water inlet 12, a first water outlet 13 and a second water outlet 14. The thermostatic chamber 24 is connected with the second water outlet 14. The valve core 2 can rotate relative to the valve body 1 around its rotation axis.

[0031] In actual applications, the first water inlet 11 can be used to access high-temperature boiled water, the second water inlet 12 can be used to access low-temperature boiled water, the first water outlet 13 can be used to provide high-temperature water for disinfection, and the second water outlet 14 can be used to provide drinking water mixed with high-temperature boiled water and low-temperature boiled water.

[0032] like Figure 1 As shown, the valve core 2 rotates to the first state relative to the valve body 1, so that the first water inlet 11 and the first water outlet 13 are connected through the adapter chamber 23 and the first water inlet 11 and the second water inlet 12 are isolated from the temperature adjustment chamber 24, so that the first water outlet 13 can increase the high-temperature water for disinfection to the pipeline.

[0033] like Figure 2 As shown, the valve core 2 rotates to the second state relative to the valve body 1, so that the first water inlet 11 and the second water inlet 12 can be connected to the temperature adjustment chamber 24 through the first temperature adjustment groove 21 and the second temperature adjustment groove 22 respectively, and the first water inlet 11 and the second water inlet 12 are separated from the transfer chamber 23. At this time, high-temperature boiled water and low-temperature boiled water can enter the temperature adjustment chamber 24 at the same time and mix, and finally discharge drinking water with suitable temperature from the second water outlet 14.

[0034] The first water inlet 11 and the second water inlet 12 can also be connected to the temperature adjustment chamber 24 through the first temperature adjustment groove 21 and the second temperature adjustment groove 22 respectively, that is, there can be only high-temperature boiled water or low-temperature boiled water in the temperature adjustment chamber 24, and the second water outlet 14 can provide high-temperature boiled water or low-temperature boiled water to the outside.

[0035] By setting the valve core 2, since the temperature regulating chamber 24, the first temperature regulating groove 21 and the second temperature regulating groove 22 are all set on the valve core 2, the number of overall components of the temperature regulating valve is relatively small, and the installation is easier. Moreover, setting the temperature regulating chamber 24, the first temperature regulating groove 21 and the second temperature regulating groove 22 on the valve core 2 will not affect the overall width of the valve core 2. Therefore, it is only necessary to control the width of the first temperature regulating groove 21 and the second temperature regulating groove 22 to increase the flow rate of the temperature regulating valve without increasing the overall width of the water mixing valve. At the same time, there is no need to additionally set a valve plate with water holes, thereby reducing the material cost of the temperature regulating valve.

[0036] Furthermore, the first temperature regulating groove 21 and the second temperature regulating groove 22 are both opened along the circumference of the valve core 2, the first temperature regulating groove 21 and the second temperature regulating groove 22 are staggered with the transfer cavity 23 along the circumference of the valve core 2, the first temperature regulating groove 21 and the second temperature regulating groove 22 are staggered vertically, the horizontal heights of the first temperature regulating groove 21 and the second temperature regulating groove 22 correspond to the horizontal heights of the first water inlet 11 and the second water inlet 12 respectively, the starting and end positions of the first temperature regulating groove 21 and the second temperature regulating groove 22 are vertically equivalent, the width of the first temperature regulating groove 21 decreases along the forward rotation direction of the valve core 2, and the width of the second temperature regulating groove 22 increases along the forward rotation direction of the valve core 2, when the first temperature regulating groove 21 and the second temperature regulating groove 22 rotate to different positions along the circumference to the positions corresponding to the first water inlet 11 and the second water inlet 12, the water inlet amount of the first temperature regulating groove 21 and the second temperature regulating groove 22 will change, thereby changing the ratio of cold and hot water in the temperature regulating cavity 24, and adjusting the water temperature of the drinking water flowing out of the second water outlet 14.

[0037] Furthermore, the valve body 1 and the valve core 2 are respectively in a centrally symmetrical cylindrical shape, the valve body 1 is sleeved on the outside of the valve core 2 and the two are concentrically arranged, the first water outlet 13, the first water inlet 11 and the second water inlet 12 are vertically arranged from top to bottom in sequence, and the vertical spatial position of the thermostatic valve can be more reasonably utilized. At the same time, when the first water inlet 11 and the second water inlet 12 begin to mix water, high-temperature boiling water flows into the thermostatic chamber 24 at the upper position, and low-temperature boiling water flows into the thermostatic chamber 24 at the lower position, which can prevent high-temperature boiling water from being directly discharged from the second water outlet 14, thereby avoiding scalding accidents.

[0038] A sealing member 3 is provided on the inner side of the valve body 1 at positions corresponding to the first water outlet 13, the first water inlet 11 and the second water inlet 12. The sealing member 3 is tightly matched with the valve body 1 and the valve core 2 respectively. The sealing member 3 is provided with through holes 31 corresponding to the first water outlet 13, the first water inlet 11 and the second water inlet 12 respectively. The sealing member 3 can ensure that the water can flow in a preset direction and prevent the water from flowing into the gap between the valve body 1 and the valve core 2.

[0039] Furthermore, a plug-in groove 15 corresponding to the seal 3 is provided on the valve body 1. The valve body 1 has an open end, and the seal 3 can enter or leave the plug-in groove 15 from the open end of the valve body 1. The plug-in groove 15 can improve the stability of the installation connection between the seal 3 and the valve body 1. When relative displacement occurs between the valve core 2 and the valve body 1, the seal 3 is not easily displaced, and the sealing effect is more stable.

[0040] Furthermore, the circumferential width of the seal 3 gradually changes toward the inner side of the valve body 1 , and the shape of the insertion groove 15 is equivalent to the shape of the seal 3 . Specifically, the shape of the seal 3 is like a dovetail shape, and the wider side of the seal 3 will not affect the internal space position of the valve body 1 .

[0041] Furthermore, an upper cover 4 is provided at the open end of the valve body 1 , and the upper cover 4 is connected and fixed to the valve body 1 . The upper cover 4 can play an effect of installing and fixing the valve body 1 and the valve core 2 .

[0042] A sealing ring 5 is provided between the upper cover 4 and the valve body 1. The sealing ring 5 is tightly matched with the upper cover 4, the valve body 1 and the sealing member 3 respectively. The sealing ring 5 can improve the sealing between the upper cover 4 and the valve body 1 and the valve core 2, and reduce the chance of water leakage.

[0043] Furthermore, a limiting rib 41 is provided on the side of the upper cover 4 facing the valve core 2, and a limiting groove 25 corresponding to the limiting rib 41 is provided on the valve core 2. The limiting rib 41 abuts against the limiting groove 25 and can slide with each other in the circumferential direction, which can improve the stability of the valve core 2 during rotation and reduce the chance of swinging of the valve core 2 during rotation.

[0044] Furthermore, the valve core 2 is connected to the transmission member 6, which can drive the valve core 2 to rotate around its rotation axis relative to the valve body 1. The transmission member 6 can drive the valve core 2 to rotate manually or electrically, thereby realizing different functions of the thermostatic valve.

[0045] Furthermore, the transmission member 6 is connected to a driving motor 7, and the driving motor 7 can drive the valve core 2 to rotate around its rotation axis relative to the valve body 1 through the transmission member 6, so that the user can more easily control the rotation of the valve core 2.

[0046] The transmission member 6 is detachably connected to the valve core 2 and the drive motor 7, respectively, so that the user can conveniently disassemble and maintain the drive motor 7. When the drive motor 7 fails, there is no need to replace the entire thermostatic valve.

[0047] In other different embodiments, the transmission member 6 is connected to a driving handle, and the driving handle can drive the valve core 2 to rotate around its rotation axis relative to the valve body 1 through the transmission member 6. The transmission member 6 is detachably connected to the valve core 2 and the driving handle respectively. The user can manually control the valve core 2 to rotate around its rotation axis relative to the valve body 1 through the driving handle through the transmission member 6.

[0048] Furthermore, a toggle portion 61 is provided on the outer side of the transmission member 6, and the drive motor 7 is electrically connected to a toggle switch (not shown in the figure). The toggle switch has a trigger portion 8. The toggle portion 61 can abut against or separate from the trigger portion 8 as the transmission member 6 rotates. The position of the trigger portion 8 can be set according to actual needs, so that when the transmission member 6 drives the valve core 2 to rotate to a preset position, the toggle portion 61 can abut against the corresponding trigger portion 8, so that the drive motor 7 stops driving the transmission member 6 to rotate, thereby improving the rotation accuracy of the valve core 2.

[0049] The above embodiments are only preferred embodiments of the present invention, and the present invention may have other embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope set by the claims of this application.
