Description

Technical Field

[0001] This utility model relates to the field of multidisciplinary technology, specifically a reed switch temperature sensing device. Background Technology

[0002] A reed switch, also known as a spool switch or magnetic reed switch, is a special type of magnetically sensitive switch invented in 1936 by Walter Ellwood of Bell Telephone Laboratories. The basic design consists of two overlapping magnetic reeds sealed inside a glass tube, with a small gap between them. When an external magnetic field is applied, the two reeds come into contact, thus conducting electricity. Once the magnet is pulled away from the switch, the reed switch returns to its original position. Reed switches are simpler in structure, smaller in size, faster, and have a longer service life than conventional mechanical switches; compared to electronic switches, they also have stronger resistance to load shocks and offer high reliability.

[0003] When reed switches are used in kitchen appliances (rice cookers, kettles, ovens) or bathroom equipment (water heaters), they are in a high-temperature and high-humidity environment. The metal contacts of the reed switches are prone to oxidation, carbon buildup, or contamination with moisture / oil, leading to poor contact or failure. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A reed switch temperature sensing device includes a container mechanism, a sealing mechanism, and a magnetic control mechanism. The container mechanism includes a container body and a lid fastened to the front side of the container body. The sealing mechanism includes two sealing rings slidably connected between the container body and the lid, a tube connected between the container body and the sealing rings, and a control valve installed on the tube body. The magnetic control mechanism includes a reed switch disposed inside the container body, multiple heat-conducting fins penetrating the outer wall of the container body, a thermosensitive deformation rod movably disposed between the multiple heat-conducting fins, a rubber head connected to one end of the thermosensitive deformation rod, and a magnet embedded on one side of the rubber head.

[0007] By adopting the above technical solution, the tank cover seals the front side of the tank body, and the joint is sealed by a sealing ring fixed to the pipe body. Then, the left control valve is opened, and the cavity is evacuated and inert gas (such as nitrogen) is injected through the corresponding pipe body. After the valve is closed, the right control valve is opened, and high-temperature resistant silicone or epoxy resin is injected through the pipe body. After curing, the resin occupies the main space of the tank body, and the residual inert gas is uniformly dispersed in the resin matrix as micron-sized bubbles, forming an inert gas-resin complementary protection system. This provides the reed switch with a moisture-proof, oxidation-proof, impact-resistant, and temperature-stable working environment, significantly extending its service life.

[0008] In a preferred embodiment, the present invention can be further configured such that two sealing rings are respectively disposed at both ends of the can lid, and the front side of the sealing rings has an integrally formed handle.

[0009] In a preferred embodiment, the present invention can be further configured such that: the other end of the thermosensitive deformation rod is set as a spherical surface, and the spherical surface is fixedly connected to one end wall of the inner cavity of the tank.

[0010] In a preferred embodiment, the present invention can be further configured such that the diameter of the rubber head is larger than the diameter of the heat-sensitive deformation rod, and the rubber head is slidably connected between multiple heat-conducting fins.

[0011] In a preferred embodiment, the present invention can be further configured such that the magnet is disposed between the reed switch and the rubber head, and the diameter of the magnet is smaller than the diameter of the thermosensitive deformation rod.

[0012] In a preferred embodiment, the present invention can be further configured such that: a bracket is fixedly connected to the other end wall of the inner cavity of the tank, and the bottom of the reed switch is fixedly connected to the top of the bracket.

[0013] In a preferred embodiment, the present invention can be further configured such that: two support legs are fixedly connected to the bottom of the tank, both support legs are located at the bottom of the bracket, and the bottoms of the two support legs are on the same horizontal plane.

[0014] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. In this invention, the can lid seals the front of the can body, and the joint is sealed by a sealing ring fixed to the pipe body. Then, the left control valve is opened, and the cavity is evacuated and inert gas (such as nitrogen) is injected through the corresponding pipe body. After closing this valve, the right control valve is opened, and high-temperature resistant silicone or epoxy resin is injected through this pipe body. After curing, the resin occupies the main space of the can body, and the residual inert gas is uniformly dispersed in the resin matrix as micron-sized bubbles, forming an inert gas-resin complementary protection system. This provides the reed switch with a moisture-proof, oxidation-proof, impact-resistant, and temperature-stable working environment, significantly extending its service life.

[0016] 2. In this utility model, when the outside of the tank is under high temperature conditions, multiple sets of heat-conducting fins efficiently conduct heat to the heat-sensitive deformation rod, causing it to elongate axially, pushing the rubber head and magnet toward the reed switch. The reed switch is closed by the magnetic field. When the temperature decreases, the heat-sensitive deformation rod contracts, and the magnet moves away, causing the reed switch to open, thereby achieving precise temperature control.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0029] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0030] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a reed switch temperature sensing device.

[0031] Example 1:

[0032] Combination Figure 1-5 As shown, the present invention provides a reed switch temperature sensing device, including a holding mechanism 100, a sealing mechanism 200 and a magnetic control mechanism 300. The holding mechanism 100 includes a tank body 110 and a can lid 120 fastened to the front side of the tank body 110.

[0033] The sealing mechanism 200 includes two sealing rings 210 slidably connected between the tank body 110 and the tank cover 120, a pipe body 220 connected between the tank body 110 and the sealing rings 210, and a control valve 230 installed on the pipe body 220.

[0034] The magnetic control mechanism 300 includes a reed switch 310 disposed inside the tank 110, a plurality of heat-conducting fins 320 penetrating the outer wall of the tank 110, a thermosensitive deformation rod 330 movably disposed among the plurality of heat-conducting fins 320, a rubber head 340 connected to one end of the thermosensitive deformation rod 330, and a magnet 350 embedded on one side of the rubber head 340.

[0035] Furthermore, two sealing rings 210 are respectively provided at both ends of the can lid 120. The front side of the sealing ring 210 is integrally formed with a handle. The sealing rings 210 can reinforce the can lid 120 and the can body 110, prevent the can lid 120 from falling off, and also improve the sealing performance at the joint between the can lid 120 and the can body 110.

[0036] Furthermore, the other end of the thermosensitive deformation rod 330 is set as a spherical surface, which is fixed to one end wall of the inner cavity of the tank 110. The spherical structure design ensures that the thermosensitive deformation rod 330 will not damage the tank 110.

[0037] Furthermore, the diameter of the rubber head 340 is larger than the diameter of the thermal deformation rod 330. The rubber head 340 is slidably connected between multiple heat-conducting fins 320. The diameter of the rubber head 340 is set so that it can be stably translated along the multiple heat-conducting fins 320.

[0038] Furthermore, the magnet 350 is disposed between the reed switch 310 and the rubber head 340. The diameter of the magnet 350 is smaller than the diameter of the thermal deformation rod 330. The size design of the magnet 350 ensures that it will not be scratched by the thermally conductive magnetic sheet 320 when it moves left and right, thus maintaining the magnetism of the magnet 350.

[0039] Example 2:

[0040] Combination Figure 2 and Figure 5 As shown, based on Embodiment 1, a bracket 400 is fixedly connected to the other end wall of the inner cavity of the tank 110, and the bottom of the reed switch 310 is fixedly connected to the top of the bracket 400. The bracket 400 is provided to support the reed switch 310 and make the reed switch 310 more securely installed.

[0041] Example 3:

[0042] Combination Figure 1 and Figure 5 As shown, in the above embodiment, the bottom of the tank 110 is fixed with two support legs 500. Both support legs 500 are located at the bottom of the bracket 400, and the bottoms of the two support legs 500 are on the same horizontal plane. The support legs 500 can improve the stability of the tank 110 when it is laid flat.

[0043] Working principle and usage process of this utility model:

[0044] When this device is put into use, the can lid 120 closes the front side of the can body 110. The sealing ring 210 fixed by the pipe body 220 achieves a stable seal at the joint between the can body 110 and the can lid 120. Then, the control valve 230 on the left side of the can lid 120 is opened, and the cavity is evacuated through the corresponding pipe body 220. After the vacuum reaches the standard, an inert gas (such as nitrogen) is injected through the same path. After the gas injection is completed, the control valve 230 is closed. Then, the control valve 230 on the right side of the can lid 120 is opened, and the cavity is filled with high-temperature resistant silicone or epoxy resin through the side pipe body 220.

[0045] After the resin cures, it occupies the main space inside the tank 110. The residual inert gas is evenly dispersed in the form of micron-sized bubbles and encapsulated in the resin matrix, forming an inert gas-resin complementary protection system. This provides the reed switch 310 with a moisture-proof, oxidation-proof, mechanical shock-resistant and temperature-stable working environment, thus extending the service life of the reed switch 310.

[0046] When the outside of the tank 110 is under high temperature conditions, multiple sets of heat-conducting fins 320 efficiently conduct heat to the heat-sensitive deformation rod 330, causing it to elongate axially and push the rubber head 340 and magnet 350 towards the reed switch 310. The reed switch 310 is closed by the magnetic field. When the temperature decreases, the heat-sensitive deformation rod 330 contracts and the magnet 350 moves away, causing the reed to open, thereby achieving precise temperature control.

[0047] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
