Description

Technical Field

[0001] This utility model relates to the shell structure of a probe-type temperature controller. Background Technology

[0002] There are many types of thermostats on the market, among which probe-type thermostats are relatively common. These thermostats work by inserting a temperature-sensing probe into the object being measured, allowing the temperature of the object to be identified through the sensing tip. Currently, thermostats on the market have excellent sealing and waterproofing performance between the temperature-sensing probe and the outer casing, but they haven't invested much in waterproofing the outer casing itself. A typical outer casing consists of a bottom shell and a top cover, and the connection between the two is particularly prone to water ingress.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] To solve the above problems, this utility model proposes a shell structure for a probe-type temperature controller. The probe-type temperature controller using this shell structure can solve the problem of shell sealing.

[0005] This utility model proposes a shell structure for an intrusion-type temperature controller, including a bottom shell and a top cover. The bottom shell has a first hole on one side for a temperature sensing rod to pass through. The side wall of the bottom shell has an annular groove on its upper end face, and an annular sealing ring is provided in the groove. The upper end face of the sealing ring protrudes from the groove. The bottom surface of the top cover has an annular convex edge, which is set corresponding to the groove and can be embedded in the groove. The top cover is placed on the upper end face of the bottom shell and fixed by screws.

[0006] In one or more embodiments, the height of the protruding edge is 0.5mm-1.5mm; the portion of the sealing ring protruding from the groove occupies 1 / 5 of its height.

[0007] In one or more embodiments, the upper end face is provided with an upwardly extending enclosure wall located inside the groove, and when the cover is connected to the bottom shell, the outer side of the enclosure wall fits against the inner side wall of the cover.

[0008] In one or more embodiments, the upper end face of the enclosure is abutted against the inner top wall of the cover.

[0009] In one or more embodiments, the bottom shell is provided with multiple connecting posts, which are located at the corners of the bottom shell. The connecting posts have threaded holes, and the face cover has a second hole corresponding to the threaded hole.

[0010] In one or more embodiments, the connecting column and the bottom shell are integrally injection molded structures.

[0011] The beneficial effects of this utility model are as follows: by setting a sealing ring on the upper end face of the side wall of the bottom shell, the sealing ring is pressed and held when the cover is connected to the bottom shell, thereby improving the sealing performance of the connection and solving the problem of poor sealing performance of the probe-type thermostat shell.

[0014] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0015] Please refer to the appendix. Figure 1-2 This utility model provides a shell structure for an intrusion-type temperature controller, including a bottom shell 1 and a top cover 2. The bottom shell has a first hole 3 on one side for a temperature sensing rod to pass through. The side wall of the bottom shell has an annular groove on its upper surface, with a depth of 2.2mm-4mm, preferably 3.0mm. An annular sealing ring 4 is provided in the groove, and the annular sealing ring is placed directly in the groove, with its upper surface protruding from the groove. The bottom surface of the top cover 2 has an annular protrusion 5, which is set corresponding to the groove and can be embedded in the groove. The top cover is placed on the upper surface of the bottom shell and fixed with screws. When the top cover is connected to the bottom shell, the protrusion extends into the groove and squeezes the sealing ring. The deformed sealing ring can improve the sealing performance, thereby improving the sealing performance at the connection between the bottom shell and the top cover.

[0016] The height of the protruding edge 5 is 0.5mm-1.5mm, preferably 1mm. The portion of the sealing ring 4 protruding from the groove accounts for 1 / 5 of its height. Using this size can ensure that the sealing ring can be fully squeezed after the protruding edge is embedded in the groove, thereby improving the sealing performance.

[0017] The upper end face is provided with an upwardly extending wall 6 located inside the groove. When the cover 2 is connected to the bottom shell 1, the outer side of the wall fits against the inner side wall 21 of the cover 2. The connection between the wall and the inner side wall of the cover can further improve the sealing performance between the bottom shell and the cover.

[0018] The upper surface of the enclosure 6 is fitted with the inner top wall 22 of the cover 2, which improves the tightness of the connection between the bottom shell and the cover and enhances the waterproof sealing performance.

[0019] The bottom shell 1 is provided with multiple connecting posts 7. The connecting posts are located at the corners of the bottom shell, avoiding the middle position to avoid occupying space. The connecting posts have threaded holes 8. The cover has a second hole 9 corresponding to the threaded hole. The cover is connected to the threaded hole by screwing a screw into the second hole.

[0020] The connecting column 7 and the bottom shell 1 are integrally injection molded structures. The injection-molded connecting column and bottom shell have a stable structure and can be exempted from subsequent reprocessing.

[0021] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
