[0001] The utility model relates to the technical field of showers, in particular to a multifunctional constant temperature water mixing valve device. Background Art

[0002] In daily life, shower equipment is an indispensable household facility. With the improvement of people's living standards and the continuous increase in their demand for comfortable experience, the demand for precise control and constant shower water temperature is becoming increasingly urgent.

[0003] However, in the prior art, the existing shower mixing valve has a relatively simple function and can usually only achieve simple mixing and adjustment of hot and cold water, but it is difficult to accurately control the water temperature. When users adjust the water temperature, they often need to try repeatedly, especially when the water pressure is unstable or the water temperature is readjusted after multiple people use it. This inconvenience is more obvious. Utility Model Content

[0004] In view of the aforementioned problems existing in the prior art, the primary purpose of this utility model is to provide a multifunctional thermostatic water mixing valve device. This device addresses the problem that existing shower mixing valves are relatively simple in functionality, typically only able to achieve simple mixing of hot and cold water, but struggle to precisely control water temperature. Users often have to repeatedly try to adjust the water temperature, especially when the water pressure is unstable or when the water temperature is readjusted after multiple users. This inconvenience is particularly pronounced.

[0005] The technical solution of the present utility model is as follows: a multifunctional constant temperature water mixing valve device includes a valve body, a dual-control mixing valve is provided inside the valve body, a scale dial is fixedly connected to one side of the valve body, and recessed scale grooves are equidistantly provided on one side of the scale dial, and the recessed scale grooves are arranged along the edge of the scale dial. A connecting shaft is installed and connected on a side of the valve body close to the scale dial and located on the central axis of the scale dial, and the connecting shaft does not contact the scale dial. An end of the connecting shaft away from the valve body is fixedly connected to a regulating handle, and an end of the connecting shaft away from the regulating handle extends to the interior of the valve body and is installed and connected to the dual-control mixing valve. A pointing groove is provided on the side of the regulating handle away from the scale dial, and the arrows of the pointing grooves are all aligned with the recessed scale grooves.

[0006] Through the above technical solution, the dial and the recessed scale groove can help users accurately find the angle and position of the last rotation, so that users can quickly adjust to the required water temperature when using it next time, thereby improving user convenience and the accuracy of water temperature adjustment. At the same time, the recessed scale groove can improve the durability of the scale. During long-term and frequent use, the recessed scale groove effectively avoids gradual wear due to friction with the external environment, long-term erosion by water stains, and possible collisions, which causes the scale to become blurred and affects the user's judgment of the water temperature adjustment position, and can keep the scale clear and legible for a long time.

[0007] As a preferred embodiment, two water inlet pipes are fixedly connected to the bottom of the valve body, and hot and cold identification grooves are provided on both sides of the outside of the valve body close to the dial, and the water inlet pipes are located below the corresponding hot and cold identification grooves.

[0008] Through the above technical solution, the presence of hot and cold identification grooves provides users with intuitive and clear guidance for identifying hot and cold water. For non-professional ordinary users or in more complex installation environments, it can effectively avoid equipment incorrect connection and operation failures caused by misjudgment of hot and cold water pipes, greatly improving the efficiency and accuracy of equipment installation and maintenance.

[0009] As a preferred embodiment, a delivery pipe is fixedly connected to the side of the valve body away from the scale plate, the delivery pipe is located between the two water inlet pipes, and a shower head is provided on the top of the delivery pipe.

[0010] Through the above technical solution, the layout of the delivery pipe and the water inlet pipe ensures that the mixed water can be efficiently and smoothly delivered from the valve body to the shower head, providing users with a comfortable shower experience.

[0011] As a preferred embodiment, a water outlet pipe is fixedly connected to the bottom of the valve body and located between the two water inlet pipes, and a switch valve is provided on the top of the valve body, and the switch valve cooperates with the water outlet pipe.

[0012] Through the above technical solution, the switch valve can control the water outlet pipe to quickly and thoroughly drain the water in the valve body when the equipment is being repaired, making it convenient for maintenance personnel to inspect, repair and replace parts of the internal structure. At the same time, when cleaning the equipment, it can effectively remove dirt, impurities and residual water in the valve body, keep the interior of the equipment clean and hygienic, and extend the service life of the equipment.

[0013] As a preferred embodiment, a sealing gasket is provided between the dial and the valve body, and the sealing gasket is made of high-temperature resistant rubber material.

[0014] Through the above technical solution, the high-temperature resistant rubber sealing gasket is a key component to ensure the sealing and stability of the equipment. During long-term use, facing factors such as water temperature changes, water pressure fluctuations and mechanical stress caused by frequent rotation of the control handle, the sealing gasket can always maintain good elasticity and sealing performance.

[0015] Compared with the prior art, the advantages and positive effects of the present invention are:

[0016] The utility model discloses a dial and a recessed scale groove, which can help users accurately find the angle and position of the last rotation, and facilitate users to quickly adjust the water temperature to the required temperature when using the water next time, thereby improving the convenience of use and the accuracy of water temperature adjustment. At the same time, the recessed scale groove can improve the durability of the scale. During long-term and frequent use, the recessed scale groove effectively avoids the friction with the external environment, the long-term erosion of water stains, and the possible wear and tear caused by factors such as collision, which leads to the blurring of the scale and affects the user's judgment of the water temperature adjustment position. The scale can be kept clear and legible for a long time. The existence of the hot and cold identification grooves provides users with an intuitive and clear guide for identifying hot and cold water. For non-professional ordinary users or in more complicated installation environments, it can effectively avoid the equipment's incorrect connection and operation failure caused by misjudging the hot and cold water pipes, thereby greatly improving the efficiency and accuracy of equipment installation and maintenance.

[0017] The layout of the delivery pipe and the water inlet pipe ensures that the mixed water can be efficiently and smoothly transported from the valve body to the shower head, providing users with a comfortable shower experience. The switch valve can control the outlet pipe to quickly and thoroughly drain the water in the valve body when the equipment is repaired, making it convenient for maintenance personnel to inspect, repair and replace parts of the internal structure. At the same time, when cleaning the equipment, it can effectively remove dirt, impurities and residual water in the valve body, keep the interior of the equipment clean and hygienic, and extend the service life of the equipment. The high-temperature resistant rubber sealing gasket is a key component to ensure the sealing and stability of the equipment. During long-term use, facing factors such as water temperature changes, water pressure fluctuations and mechanical stress caused by frequent rotation of the control handle, the sealing gasket can always maintain good elasticity and sealing performance.

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, the utility model provides a technical solution: it includes a valve body 1, a double-control mixing valve is provided inside the valve body 1, a scale dial 2 is fixedly connected to one side of the valve body 1, and recessed scale grooves 3 are equidistantly provided on one side of the scale dial 2. The recessed scale grooves 3 are arranged along the edge of the scale dial 2, and a connecting shaft 11 is installed and connected on the side of the valve body 1 close to the scale dial 2 and located on the central axis of the scale dial 2. The connecting shaft 11 does not contact the scale dial 2, and an end of the connecting shaft 11 away from the valve body 1 is fixedly connected to a regulating handle 4, and an end of the connecting shaft 11 away from the regulating handle 4 extends to the interior of the valve body 1 and is installed and connected to the double-control mixing valve, and a pointing groove 5 is provided on the side of the regulating handle 4 away from the scale dial 2, and the arrows of the pointing groove 5 are all aligned with the recessed scale groove 3.

[0026] In this embodiment, when the user rotates the control handle 4, the connecting shaft 11 rotates accordingly, and the rotational motion is transmitted to the valve core in the dual-control mixing valve, thereby changing the valve core's opening degree to the hot and cold water channels, thereby adjusting the hot and cold water mixing ratio. The dial 2 is fixed to one side of the valve body 1, and its edge is equidistantly arranged with graduated grooves 3, and the graduated grooves 3 are recessed. The control handle 4 is connected to the valve body 1 via the connecting shaft 11, which is located at the center axis of the dial 2 and does not contact it. The control handle 4 is provided with a pointing groove 5 on the side away from the dial 2, and the arrow of the pointing groove 5 is always aligned with the graduated groove 3. The user can accurately determine the rotation angle of the control handle 4 based on the position of the graduated groove 3 that the pointing groove 5 is aligned with, and thus know the opening state of the dual-control mixing valve valve core, achieving precise adjustment of the water temperature. At the same time, the user can quickly and accurately find the last set water temperature position after multiple uses.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, two water inlet pipes 8 are fixedly connected to the bottom of the valve body 1, and hot and cold identification grooves 6 are provided on the outside of the valve body 1 and on both sides close to the dial 2, and the water inlet pipes 8 are located below the corresponding hot and cold identification grooves 6.

[0028] In this embodiment, two water inlet pipes 8 are fixedly connected to the bottom of the valve body 1, serving as inlets for cold and hot water, respectively. Hot and cold indicator slots 6 on the outside of the valve body 1, near either side of the dial 2, clearly indicate whether the corresponding water inlet pipe 8 is receiving cold or hot water.

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a delivery pipe 7 is fixedly connected to the side of the valve body 1 away from the dial 2. The delivery pipe 7 is located between the two water inlet pipes 8. A shower head is provided on the top of the delivery pipe 7.

[0030] In this embodiment, a delivery pipe 7 is fixedly connected to the side of the valve body 1 away from the dial 2, and its position is between the two water inlet pipes 8. After the hot and cold water are mixed in the dual-control mixing valve according to the set ratio, the mixed water is stably delivered to the shower head on the top through the delivery pipe 7 under the action of the pressure difference.

[0031] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a water outlet pipe 10 is fixedly connected to the bottom of the valve body 1 and located between the two water inlet pipes 8. A switch valve 9 is provided on the top of the valve body 1, and the switch valve 9 cooperates with the water outlet pipe 10.

[0032] In this embodiment, a water outlet pipe 10 is fixedly connected to the bottom of the valve body 1, located between the two water inlet pipes 8. An on-off valve 9 is provided at the top of the valve body 1. When the on-off valve 9 is opened, water in the valve body can flow out through the water outlet pipe 10 due to gravity or pressure differential. The water outlet pipe 10 is useful for equipment maintenance, cleaning, or specific drainage needs.

[0033] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, a sealing gasket is provided between the dial 2 and the valve body 1, and the sealing gasket is made of high-temperature resistant rubber.

[0034] In this embodiment, a sealing gasket made of high-temperature resistant rubber material is provided between the dial 2 and the valve body 1. When the user rotates the control handle 4 to adjust the water temperature, the sealing gasket forms a tight sealing structure around the connecting shaft 11, effectively preventing water from leaking from the connection gap between the dial 2 and the valve body 1.

[0035] Working principle:

[0036] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, when the user rotates the control handle 4, the connecting shaft 11 rotates accordingly, transmitting the rotational motion to the valve core within the dual-control mixing valve, thereby changing the valve core's opening relative to the hot and cold water channels and adjusting the mixing ratio of the hot and cold water. A dial 2 is fixed to one side of the valve body 1, with graduated grooves 3 arranged equidistantly along its edge. The grooves 3 are recessed. The control handle 4 is connected to the valve body 1 via a connecting shaft 11, which is located at the center axis of the dial 2 but does not contact it. A pointing groove 5 is located on the side of the control handle 4 facing away from the dial 2, with the arrow on this pointing groove 5 always aligned with the graduated groove 3. Based on the position of the graduated groove 3 that the pointing groove 5 aligns with, the user can accurately determine the rotation angle of the control handle 4 and, therefore, the opening state of the dual-control mixing valve core, achieving precise water temperature adjustment. This allows for quick and accurate retrieval of the last set water temperature during repeated use. Two water inlet pipes 8 are fixedly connected to the bottom of the valve body 1, serving as the inlet for cold and hot water, respectively. The hot and cold marking grooves 6 on the outside of the valve body 1, close to both sides of the dial 2, clearly indicate whether the corresponding water inlet pipe 8 is connected to cold water or hot water through specific markings;

[0037] A delivery pipe 7 is fixedly connected to the side of the valve body 1 away from the dial 2, and its position is between the two water inlet pipes 8. When the cold and hot water are mixed in the dual-control mixing valve according to the set ratio, the mixed water is stably delivered to the shower head at the top through the delivery pipe 7 under the action of the pressure difference. A water outlet pipe 10 is fixedly connected to the bottom of the valve body 1 and located between the two water inlet pipes 8. A switch valve 9 is provided on the top of the valve body 1. When the switch valve 9 is opened, the water in the valve body can flow out through the water outlet pipe 10 under the action of gravity or pressure difference. The water outlet pipe 10 can play a role in equipment maintenance, cleaning or specific drainage requirements. A sealing gasket made of high-temperature resistant rubber is provided between the dial 2 and the valve body 1. When the user rotates the control handle 4 to adjust the water temperature, the sealing gasket forms a tight sealing structure around the connecting shaft 11, effectively preventing water from leaking from the connection gap between the dial 2 and the valve body 1.
