[0024] Referring to the accompanying drawings of the specification, a temperature regulating device includes a body 10 having a temperature regulating chamber 11 and a water outlet channel 12. The temperature regulating chamber is used to mix hot water and cold water to achieve temperature regulation, and the regulated water flow flows out through the water outlet channel. The temperature regulating chamber and the water outlet channel are in communication. A temperature regulating module 20 is arranged in the temperature regulating chamber. The temperature regulating module controls the flow rates of the hot water and cold water entering the temperature regulating chamber, thereby achieving the regulation of the water temperature. The body is further provided with an installation chamber 13, a first water inlet channel 14 and a second water inlet channel 15. The installation chamber and the body can be separately arranged or integrally arranged. The water flows in the first water inlet channel and the second water inlet channel can flow into the installation chamber. Among them, the first water inlet channel can be a cold water inlet channel, and the second water inlet channel can be a hot water inlet channel. A water flow stabilizer 30 is arranged in the installation chamber. The water flow stabilizer can make the temperature regulation more stable and faster when the pressure difference between the two water inlet ends is large, improving safety. The water flow stabilizer can adjust the water pressures of the hot water and cold water. A first opening 16 for communicating the water flow in the first water inlet channel to the temperature regulating chamber is arranged between the installation chamber and the temperature regulating chamber. A second opening 17 for communicating the water flow in the second water inlet channel to the temperature regulating chamber is arranged between the installation chamber and the temperature regulating chamber. The water flow stabilizer can reduce the flow rate difference of the water flows flowing into the temperature regulating chamber from the first opening and the second opening. Preferably, the water flow stabilizer can make the water flow pressures flowing into the temperature regulating chamber from the first opening and the second opening close or equal.
[0025] Preferably, the temperature regulating module includes a moving shaft 21 that can move in the temperature regulating chamber. The moving shaft can be two symmetrically arranged conical bodies. The movement of the moving shaft can adjust the flow rates of the water flows flowing into the temperature regulating chamber from the first opening and the second opening, and control the flow rate ratio of the water flows flowing into the temperature regulating chamber from the first opening and the second opening by the movement of the moving shaft, thereby achieving precise regulation of the water temperature of the water flow flowing out through the water outlet channel.
[0026] Further, the temperature adjustment module further includes a motor 22, a temperature detector 23, and a control module (not shown in the figure) connected to each other. The motor can drive the movement of the moving shaft. The temperature detector is arranged on the water outlet channel. The temperature detector sends a signal to the control module, causing the control module to drive the motor to operate. By detecting the temperature of the water flow in the water outlet channel and then feeding it back to the control module, the control module controls the forward and reverse rotation of the motor, thereby realizing the rise or fall of the moving shaft and completing the adjustment of the outlet water temperature. The control part of the control module is similar to the prior art and will not be elaborated in detail herein.
[0027] In an embodiment, the water flow stabilizer includes a housing 31. A sealing ring 32 that can cooperate with the inner peripheral wall of the installation chamber is arranged on the outer periphery of the housing. In this way, the installation chamber on the outer periphery of the housing can be divided into two non-connecting chambers. A first water inlet 311 that can communicate with the first water inlet channel is arranged on the side wall of the housing above the sealing ring. A first water outlet 312 that can communicate with the first opening is also arranged on the side wall of the housing. A second water inlet 313 that can communicate with the second water inlet channel is arranged on the side wall of the housing below the sealing ring. A second water outlet 314 that can communicate with the second opening is also arranged on the side wall of the housing. That is to say, the adjustment of the water pressure is carried out inside the housing, and the pressure difference of the water flow flowing out from the first water outlet and the second water outlet is reduced. Specifically, a hollow movable shaft 33 is further arranged inside the housing. The movable shaft can move up and down inside the housing under the action of the pressure difference between the first water inlet channel and the second water inlet channel. That is to say, when the water pressure of the first water inlet channel is greater than the water pressure of the second water inlet channel, the movable shaft moves downward, thereby reducing the water flow entering the upper cavity, thereby reducing the water pressure of the first water inlet channel until the water pressures of the two water flows are adjusted to a balanced state. A baffle 331 is arranged in the middle of the movable shaft. A first inlet 332 corresponding to the first water inlet is arranged on the side wall of the movable shaft above the baffle. A second inlet 333 corresponding to the second water inlet is arranged on the side wall of the movable shaft below the baffle. An upper cavity 334 that can communicate with the first water outlet is formed inside the movable shaft above the baffle. A lower cavity 335 that can communicate with the second water outlet is formed inside the movable shaft below the baffle. The cooperation between the first inlet and the first water inlet can form a water passing area, and the cooperation between the second inlet and the second water inlet can form another water passing area. By moving the movable shaft, one or both of these two water passing areas can be changed, realizing the adjustment of the water flow rates entering the upper cavity and the lower cavity, thereby realizing the adjustment of the water pressure. Among them: the inlet hole diameters on both sides of the baffle are equal. When the two water inlet pressures are equal, the two ends of the water inlet hole where the movable shaft cooperates with the side wall are equal. When there is a pressure difference between the two sides, the movable shaft moves towards the end with a smaller pressure. The water inlet cross-section area of the end with a smaller pressure becomes larger, larger than that of the end with a larger pressure, thereby reducing the flow rate difference between the water inlets at both ends.
[0028] Further, an active clearance is provided between the outer periphery of the movable shaft located on the periphery of the baffle and the inner peripheral wall of the housing, so that a very small amount of water flow can circulate between the two cavities, without affecting the temperature regulation.
[0029] Referring to the accompanying drawings of the specification, step surfaces 315 capable of abutting against the movable shaft are provided at the upper and lower ends of the inner periphery of the housing, and the step surfaces can be used to limit the moving stroke of the movable shaft within the housing.
[0030] More specifically, the present utility model mainly includes: a first water inlet channel for the first fluid (cold water) to enter; a second inlet channel for the second fluid (hot water) to enter; a mixing temperature adjustment cavity for mixing the first fluid, the second fluid, or both of them; a water flow stabilizer: a water flow stabilizer is added between the temperature adjustment module and the two water inlet channels, so that the first fluid and the second fluid enter the installation chamber before entering the temperature adjustment cavity. When the water pressures at both ends are different and enter the water flow stabilizer, the two pressures are close when output from the water flow stabilizer, and finally a relatively stable water inlet is provided for the rear-end temperature adjustment module. The water flow stabilizer includes: a movable shaft, a housing, etc. The movable shaft is movably assembled in the component. The housing includes a structure with two water inlets and two water outlets. The shapes and sizes of the two water inlets are close or the same, and are arranged to cooperate with the movable shaft to adjust the size of the water inlet area. The water inlet flow rates of the two fluids change with the change of the position of the movable shaft due to the water pressure. When the pressures of the two fluids are the same, the water inlet areas of the upper cavity and the lower cavity are the same. When there is a difference in the two water inlet pressures, the water inlet area at the end with a smaller pressure is larger, and the water inlet area at the end with a larger pressure is smaller. A movable shaft is placed between the first fluid and the second fluid and into the temperature adjustment cavity. Under the action of the driving device, the movable shaft reciprocates between the first opening and the second opening to control the water inlet ratio of the two. During the movement of the movable shaft, it follows the principle of thermo-convection for temperature adjustment: Energy = density * volume * temperature difference and the Bernoulli equation of the horizontal flow tube. The temperature adjustment area of the movable shaft is characterized by being divided into two parts: a cold water flow control area and a hot water flow control area. The shapes of the two control areas are in a face-to-face or back-to-back structure.
[0031] The above description shows and describes the preferred embodiments of the present utility model. As mentioned above, it should be understood that the present utility model is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications, and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the technology or knowledge in the relevant field. And any changes and modifications made by those skilled in the art without departing from the spirit and scope of the present utility model shall fall within the protection scope of the appended claims of the present utility model.
