[0039] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] like Figures 1 to 7 As shown, an automatic water temperature control device provided in this embodiment includes: a base 1, a hot water pipe 2, a cold water pipe 3, a water outlet pipe 4, a mixing seat 5, a mounting seat 6, an adjusting plug 7, a driving device 8 and a controller.

[0041] like Figures 1 to 7 As shown, the water mixing seat 5 and the mounting seat 6 are both fixedly mounted on the base 1. Among them, the middle part of the water mixing seat 5 is provided with an adjustment channel 51 extending in the left-right direction, and the middle part of the water mixing seat 5 is provided with a hot water groove 52 and a cold water groove 53 in parallel upward, and the bottom of the hot water groove 52 is provided with a hot water groove 54 connected to the hot water groove 52, and the bottom of the cold water groove 53 is provided with a cold water groove 55 connected to the hot water groove 53; and the hot water groove 54 and the cold water groove 55 are both connected to the adjustment channel 51. Then, the hot water pipe 2 is installed in the hot water groove 52 and hot water is passed into the hot water groove 52, and the cold water pipe 3 is installed in the cold water groove 53 and cold water is passed into the cold water groove 53. At the same time, the middle part of the water mixing seat 5 is provided with a water mixing groove 56 downward, and the top of the water mixing groove 56 is provided with a water mixing groove 57 connected to the mixing groove 57, and the water mixing groove 57 is connected to the adjustment channel 51. The hot water and cold water coming out of the hot water pipe 2 and the cold water pipe 3 are mixed in the adjustment channel 51, and then go out of the water mixing groove 56 through the water mixing groove 57.

[0042] Meanwhile, a water outlet channel 61 is provided on the mounting seat 6, one end of the water outlet channel 61 is connected to the water mixing groove 56, and the water outlet pipe 4 is installed at the other end of the water outlet channel 61. The water in the water mixing groove 57 flows out from the water outlet pipe 4 through the water outlet channel 61.

[0043] like Figures 1 to 4 As shown, the regulating plug 7 can be moved left and right and is installed in the regulating channel 51. Two annular grooves 71 are provided in the middle of the regulating plug 7. There is a boss 72 between the two grooves 71. The width of the boss 72 is not less than the width of the hot water groove 54 and the cold water groove 55. When the boss 72 moves to the bottom of the hot water groove 54, only cold water enters the regulating channel 51. When the boss 72 moves to the bottom of the cold water groove 55, only hot water enters the regulating channel 51. The upper and lower limits of the temperature can be reached. At the same time, the width of the boss 72 is less than the sum of the spacing between the hot water groove 54 and the cold water groove 55, the width of the hot water groove 54 and the width of the cold water groove 55; the boss 72 cannot block the hot water groove 54 and the cold water groove 55 at the same time, ensuring that water can enter the regulating channel 51. The width of the groove 71 is not less than the width of the hot water groove 54 and the cold water groove 55, ensuring the maximum flow rate of the hot water groove 54 or the cold water groove 55 in the regulating channel 51.

[0044] At the same time, a recessed platform 73 is provided on the side of the boss 72 facing the water mixing channel. The recessed platform 73 does not contact the side wall of the regulating channel 51, and the space enclosed by the recessed platform 73 and the regulating channel 51 is connected to the two grooves 71; the water in the two grooves 71 can be mixed in the space enclosed by the recessed platform 73 and the regulating channel 51, and then enter the water mixing groove 57.

[0045] like Figures 1 to 7 As shown, both the hot water groove 54 and the cold water groove 55 are rectangular structures, and the extension direction of the length in the rectangular structures of the hot water groove 54 and the cold water groove 55 is the left-right direction. The regulating piston changes the area of ​​the hot water inlet and the cold water inlet by moving left and right, thereby adjusting the water inlet to achieve the goal of changing the outlet water temperature. The hot water groove 54 and the cold water groove 55 are made into a rectangle. When the width remains unchanged, as the piston moves, the cross-sectional area of ​​the water inlet is proportional to the length. Move the regulating piston left and right, that is, adjust the length of the hot water groove 54 and the cold water groove 55 interlaced with the groove 71, respectively, and then adjust the cross-sectional area of ​​the water inlet, so that the water temperature can be quickly and correctly adjusted.

[0046] At the same time, the water mixing groove 57 is a rectangular structure, and the extension direction of the rectangular structure is perpendicular to the left and right direction. In this way, the water mixing groove 57 can always be located below the concave platform 73, ensuring that the water mixing groove 57 is always in a fully open state without affecting the water output.

[0047] The regulating plug 7 is provided with an annular sealing groove 74 at both ends, and a sealing ring 75 is provided in the sealing groove 74. The sealing grooves 74 at both ends are respectively located on the left and right sides of the two grooves 71. The water in the regulating channel 51 will not flow out from the left and right ends, which is safe and reliable.

[0048] like Figures 1 to 4As shown, the driving device 8 drives the connected regulating plug 7 to move left and right in the regulating channel 51. The driving device 8 is connected to a controller, and the controller controls the connected driving device 8.

[0049] Among them, the driving device 8 includes a driving motor 81, a driving gear 82, and a driven rack 83; the driving motor 81 is installed on the base 1, the driving gear 82 is coaxially fixed to the output end of the driving motor 81, and the driven rack 83 is fixed on the adjusting plug 7. The driving gear 82 and the driven rack 83 are meshed. When the driving motor 81 drives the driving gear 82 to rotate, the driven rack 83 moves left and right, thereby driving the adjusting plug 7 to move left and right in the adjusting channel 51.

[0050] In this embodiment, a through slot 84 extending in the left-right direction is provided in the middle of the driven rack 83, and teeth cooperating with the driving gear 82 are provided on one side wall of the through slot 84. The driving gear 82 extends into the through slot 84 and meshes with the teeth on the side wall of the through slot 84. This makes the cooperation between the driving gear 82 and the driven rack 83 safer and more stable, and the operation more reliable.

[0051] Furthermore, the driving motor 81 is controlled by a controller, and the controller controls the rotation direction and rotation speed of the driving motor 81, thereby adjusting the water inflow of hot and cold water to achieve the purpose of adjusting the outlet water temperature.

[0052] Furthermore, a detection channel 62 connected to the water outlet channel 61 is provided on the mounting seat 6, and a temperature sensing rod of a temperature detection device is provided in the detection channel 62 for detecting the water temperature of the water outlet channel 61; the temperature detection device is connected to the controller. At the same time, a temperature adjustment device 9 is provided on the controller, and a display for displaying the real-time temperature and the set temperature is provided on the temperature adjustment device 9, and a temperature setting button is provided on the temperature adjustment device 9, and the temperature adjustment device 9 is connected to the temperature detection device.

[0053] During operation, when the temperature detected by the temperature sensing rod is lower than the set temperature, the controller controls the driving motor 81 to rotate forward, the regulating plug 7 moves, the water inflow of hot water increases, and the outlet water temperature increases; on the contrary, when the temperature detected by the temperature sensing rod is higher than the set temperature, the controller controls the driving motor 81 to rotate reversely, the regulating plug 7 moves in the opposite direction, the water inflow of cold water increases, and the outlet water temperature decreases. The operation is convenient, and the outlet water temperature can be adjusted by adjusting the position of the regulating plug 7 in real time.

[0054] This device is also equipped with a monitoring device for detecting the temperature and pressure in the hot water pipe 2 and the cold water pipe 3, and the detection device is connected to the controller, which can adjust the amount of cold and hot water entering in real time according to the inlet water temperature and pressure. For the user, only the desired temperature needs to be input, and a stable temperature can be obtained after 3 seconds. If it needs to be changed, it can be input again.

[0055] After long-term verification, we have proposed a new solution: input the desired temperature value, sense the temperature in real time at the water outlet and feed it back to the controller, the controller compares the temperature difference between the real-time temperature and the input temperature, sends instructions to the drive motor 81, and the drive motor 81 moves to adjust the proportion of hot water and cold water entering. The above is a working cycle with a cycle time of 1 second. After 2 to 3 working cycles, the water temperature can reach the input temperature, and can make real-time adjustments as the inlet water temperature or pressure changes to ensure the stability of the outlet water temperature.

[0056] The automatic water temperature control device can sense and adjust rapidly in real time when the inlet water temperature and pressure are unstable, ensuring the outlet water temperature is stable, safe and reliable.

[0057] The present invention is a novel technical solution rather than limiting it. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some or all of the technical features can be replaced by equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solutions of the embodiments of the present invention.
