For example, it can be fixedly connected and arranged, or detachably connected and arranged, or integrally connected and arranged. For those of ordinary skill in the art, the specific meanings of the above terms in this patent can be understood according to specific situations.

[0028] Please refer to Figures 1 to 3 , an embodiment discloses a diaphragm of a diaphragm valve with a chip. The diaphragm valve includes a first cavity, and a first sealing member and a second sealing member are arranged inside the first cavity. The diaphragm includes a first membrane member 1 and a second membrane member 2 arranged at one end of the first membrane member 1. The first membrane member 1 is correspondingly arranged with the first sealing member, and the second membrane member 2 is correspondingly arranged with the second sealing member;

[0029] The second membrane member 2 includes a second body 22, and a temperature sensing member 23 is arranged on one side surface of the second body 22. The temperature sensing member 23 is configured to detect the temperature of the fluid in the first cavity.

[0030] In the above embodiments, the first cavity is the main area through which the fluid flows. The first sealing member and the second sealing member arranged inside it are used for the sealing isolation of the fluid. The diaphragm serves as the actuating component of the diaphragm valve and realizes the on-off control of the fluid through up and down movement. In this embodiment, the diaphragm is divided into two parts, namely the first diaphragm member and the second diaphragm member, which cooperate with the first sealing member and the second sealing member respectively to form a double-sealing structure to improve the sealing effect. The first sealing member and the second sealing member can be made of elastic materials so as to adapt to the shape change when the diaphragm moves and maintain a good sealing effect. In one embodiment, in order to improve the sealing performance, the surfaces of the first sealing member and the second sealing member can be provided with structures such as sealing grooves or sealing protrusions to increase the contact area and sealing tightness with the diaphragm. The first diaphragm member and the second diaphragm member form a whole so as to be able to move coordinately with each other during the opening or closing process of the valve. When an external force acts on the diaphragm, the first diaphragm member and the second diaphragm member will move simultaneously, thereby realizing the opening or closing of the valve. The second diaphragm member includes a second body and a temperature sensing component arranged inside the second body. The temperature sensing component can be a thermistor, a thermocouple or other types of temperature sensors, which are used to directly detect the temperature of the fluid in the first cavity. By integrating the temperature sensing function, the real-time monitoring of the fluid temperature can be realized, and further the state of the valve body can be controlled. For example, when the fluid temperature is too high, the valve is closed to prevent the fluid from circulating in the system, improving the accuracy and stability of the system. In one embodiment, the temperature sensing component is arranged at one end close to the water outlet inside the second diaphragm member for the convenience of maintenance and replacement. When the temperature sensing component fails or needs to be calibrated, only the second diaphragm member needs to be disassembled for replacement or maintenance, without disassembling the entire diaphragm valve.

[0031] Please continue to refer to Figure 2 , in one embodiment, the first diaphragm member 1 includes a first body 11. A first connecting member 12 is arranged on one side of the first body 11 close to the second body 22. A second connecting member 21 corresponding to the first connecting member 12 is arranged on one side of the second body 22 close to the first body 11. Among them, the first body 11 and the second body 22 are detachably connected through the first connecting member 12 and the second connecting member 21.

[0032] In the above embodiments, the detachable manner between the first connecting member 12 and the second connecting member 21 is not specifically limited in this application document. Threaded, snap-fit, pin and other detachable connection methods can be adopted to conveniently realize the connection and disassembly between the first membrane member 1 and the second membrane member 2. Specifically, when it is necessary to connect the first membrane member 1 and the second membrane member 2, align the first connecting member 12 with the second connecting member 21, and apply an appropriate force or rotational movement to achieve a tight connection. Similarly, when disassembly is required, simply perform the reverse operation to easily separate the first membrane member 1 and the second membrane member 2. The detachable connection facilitates the replacement and maintenance of the membrane. When one of the first membrane member 1 or the second membrane member 2 is damaged, the damaged part can be disassembled and replaced with an undamaged membrane member.

[0033] Please continue to refer to Figure 2 , furthermore, a threaded groove is arranged at one end of the first connecting member 12 close to the second body 22; the second connecting member 21 is arranged in a columnar shape, and threads are arranged on its surface; wherein, in the connected state of the first membrane member 1 and the second membrane member 2, the second connecting member 21 is connected to the first connecting member 12 through the surface threads and the threaded groove. When the first membrane member 1 and the second membrane member 2 need to be connected, just insert the second connecting member 21 into the threaded groove of the first connecting member 12 and rotate the second connecting member 21 to achieve a tight connection. Similarly, when disassembly is required, just rotate the second connecting member 21 in the reverse direction to easily separate the first membrane member 1 and the second membrane member 2.

[0034] Please continue to refer to Figure 3 , in one embodiment, a groove member is arranged on the side of the second body 22 away from the first membrane member 1, and a temperature sensing member 23 is arranged in the groove member area. The groove member provides an installation space for the temperature sensing member 23. The temperature sensing member 23 can be fixedly embedded on the second body 22 by snap-fit or adhesion and is in direct contact with the fluid, so as to accurately detect the temperature of the fluid. In the embodiment, the temperature sensing member 23 is arranged on the side of the second body 22 away from the first membrane member 1. When there is liquid flowing from the water inlet, the impact force will not directly act on the temperature sensing member 23, thereby prolonging the service life of the temperature sensing member 23.

[0035] Please continue to refer to Figure 1 , Figure 1 At the position in [], there is a first sealing member. The first sealing member includes a first sealing portion. The first sealing portion is arranged in a ring shape and is provided with a first sealing cavity. The outer surface size of the first body 11 corresponds to the first sealing cavity; one end of the limiting member is embedded in the first sealing cavity, and the limiting member is provided with a limiting groove along the direction perpendicular to the first sealing cavity; wherein, the inner diameter of the inner wall of the limiting groove is paired with the outer diameter of the first connecting member 12, and the first connecting member 12 is slidably connected to the limiting groove.

[0036] In the embodiment, the first sealing portion is arranged in a ring shape and has a first sealing cavity inside. The size of the first sealing cavity is arranged corresponding to the outer surface size of the first body, ensuring that the first body can be tightly embedded in the first sealing cavity to form an effective seal. When the diaphragm valve is closed, the first sealing portion can effectively prevent fluid from leaking from the valve, ensuring the sealing performance of the fluid system. One end of the limiting member is embedded in the first sealing cavity, and a limiting groove is arranged in a direction perpendicular to the first sealing cavity. The inner wall diameter of the limiting groove is paired with the outer wall diameter of the first connecting member, so that the first connecting member can be slidably connected in the limiting groove. During the membrane switching process, the first connecting member will slide along the limiting groove, ensuring the accurate movement track of the membrane.

[0037] In summary, the present utility model discloses a diaphragm valve membrane with a chip. Its structure includes a first cavity, which serves as the main channel for fluid flow. Inside, a first sealing member and a second sealing member are carefully configured to ensure effective isolation of the fluid. The membrane structure is unique, consisting of a first membrane member and a second membrane member, which respectively correspond to the above-mentioned sealing members to form a strong double-sealing system, significantly improving the sealing efficiency. The first and second sealing members are made of elastic materials, which can flexibly adapt to shape changes with the movement of the membrane and maintain an excellent sealing state. In some embodiments, sealing grooves or protrusions are added to the surface of the sealing member to further enhance the contact area and tightness with the membrane. The second membrane member is internally provided with a temperature sensing member, such as a thermistor or a thermocouple, to directly monitor the temperature of the fluid in the first cavity. This design not only realizes real-time monitoring of the fluid temperature but also can intelligently control the valve body state according to the temperature situation. For example, when the fluid temperature is too high, the valve is closed to effectively prevent overheated fluid from circulating in the system, significantly improving the accuracy and operating stability of the system. The temperature sensing member is installed inside the second membrane member and near the water outlet, and it can be completed only by simply disassembling the second membrane member, greatly reducing the maintenance difficulty and cost.

[0038] The above are only the preferred embodiments of the present utility model. It should be pointed out that for those skilled in the art, without departing from the concept of the present utility model, several deformations and improvements can be made, and these should also be regarded as the protection scope of the present utility model, which will not affect the implementation effect of the present utility model and the practicability of the patent.
