Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, in particular to a conveniently disassembled temperature controller. Background Art

[0002] In order to ensure the safety of the electric rice cooker during the heating process, a thermostat is required to control the on and off of the heating process. The existing thermostat usually includes a housing, a thermistor and a fuse. The thermistor and the fuse are encapsulated inside the housing by pouring epoxy resin into the housing. However, when the temperature of the electric rice cooker is too high, the fuse will blow to protect the safety of the electric rice cooker. After the fuse is disconnected, the thermostat will be scrapped and needs to be replaced, which greatly increases the cost of maintenance. Utility Model Content

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] like Figure 1-4 As shown, a thermostat that is easy to disassemble includes a shell 1, a thermistor 2, a fuse 3 and an insulating heat-conducting bracket 4. The bottom of the shell 1 is provided with a receiving groove 5 for accommodating the insulating heat-conducting bracket 4, and the top of the insulating heat-conducting bracket 4 is respectively provided with a thermistor placement groove 10 and a fuse placement groove 11 for placing the thermistor 2 and the fuse 3. Both ends of the thermistor 2 are connected with a thermistor wire 12, and both ends of the fuse 3 are connected with a fuse wire 13. The bottom of the insulating heat-conducting bracket 4 is respectively provided with a thermistor placement groove 10 and a fuse hole connected with the fuse placement groove 11. The thermistor wire 12 passes through the thermistor hole, and the fuse wire 13 passes through the fuse hole, so that the thermistor 2 and the fuse 3 can be conveniently taken and placed on the insulating heat-conducting bracket 4;

[0022] The outer support 6 is fixedly connected to the opposite sides of the insulating heat-conducting bracket 4, and the receiving groove 7 is provided on the opposite sides of the receiving groove 5. The inner support 8 that is engaged with the outer support 6 is provided inside the receiving groove 7. The inner walls on the opposite sides of the receiving groove 7 are provided with slide grooves 14. The inner support 8 is fixedly connected with a slider 15 that is slidably connected with the slide groove 14. The upper part of the outer support 6 and the lower part of the inner support 8 are inclined surfaces that cooperate with each other. The side of the inner support 8 away from the outer support 6 is fixedly connected with a spring 16. The end of the spring 16 away from the inner support 8 is fixedly connected to the inner wall of the receiving groove 7. By pushing the insulating heat-conducting bracket 4 to slide into the interior of the receiving groove 5, the outer support 6 can push the inner support 8 to slide into the interior of the receiving groove 7. At this time, the spring 16 is in a compressed state. When the outer support 6 is completely moved to the top of the inner support 8, the elastic action of the spring 16 will push the inner support 8 to pop out, so that the bottom of the outer support is engaged with the top of the inner support, and then the insulating heat-conducting bracket 4 is fixed to the interior of the receiving groove 5;

[0023] A groove 18 is provided on the outer wall of the outer shell 1, and a through hole 17 connected to the storage groove 7 is provided inside the groove 18. A pull rod 9 is fixedly connected to the side of the inner support 8 away from the outer support 6. The end of the pull rod 9 away from the inner support 8 passes through the through hole 17 and is fixedly connected to a handle 19. The handle 19 is located inside the groove 18. The pull rod 9 is pulled by the handle 19 to drive the inner support 8 to slide into the interior of the storage groove 7.

[0024] Working principle:

[0025] like Figure 1-4 As shown, when assembling the thermostat, first place the thermistor 2 and the fuse 3 in the thermistor placement slot 10 and the fuse placement slot 11 of the insulating heat-conducting bracket 4, and then push the insulating heat-conducting bracket 4 to slide into the interior of the receiving slot 5, so that the outer bracket 6 can push the inner bracket 8 to slide into the interior of the storage slot 7. At this time, the spring 16 is in a compressed state. When the outer bracket 6 is completely moved to the top of the inner bracket 8, the elastic action of the spring 16 will push the inner bracket 8 to pop out, so that the bottom of the outer bracket is clamped on the top of the inner bracket, and then the insulating heat-conducting bracket 4 is fixed in the interior of the receiving slot 5;

[0026] When the thermistor 2 fails or the fuse 3 blows and needs to be replaced, the pull rod 9 is pulled by the handle 19 to drive the inner support 8 to slide into the storage groove 7, so that the outer support 6 loses its support, and the insulating heat-conducting bracket 4 will be detached from the inside of the shell 1. In this way, the thermistor or fuse can be replaced separately, which greatly reduces the cost of maintenance.

[0027] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
