Abstract
Description
Technical Field
[0001] The utility model relates to the field of temperature controllers, in particular to a temperature controller probe rod structure. Background Art
[0002] Probe-type thermostats are often used in various equipment that require temperature control, such as water heaters, disinfection cabinets, and electric cooking appliances. The probe rod of the probe thermostat is filled with kerosene. When producing the probe rod, it is necessary to first pour kerosene into the probe rod, and then weld the pouring position tightly to seal the inside of the probe rod to prevent kerosene leakage. However, at the current stage of producing probe rods, due to unreasonable structural planning and design of the probe rod, kerosene spills from time to time.
[0003] Therefore, it is necessary to make further improvements. Utility Model Content
[0004] In order to solve the above problems, the utility model proposes a probe rod structure for a temperature controller, which has a reasonable design and can avoid the problem of kerosene spilling during production.
[0005] The utility model proposes a temperature controller probe rod structure, which comprises a tube body, an insertion head and a tail cover. The interior of the tube body is a hollow structure. The rear end of the insertion head has an annular front connecting wall connected to the front end of the tube body, the front connecting wall is inserted into the tube body and fits with the inner wall of the tube body, and the connection between the insertion head and the tube body is fixed by welding. The front end of the tail cover has an annular rear connecting wall connected to the rear end of the tube body, the rear connecting wall is inserted into the tube body and fits with the inner wall of the tube body, and the connection between the tail cover and the tube body is fixed by welding.
[0006] In one or more embodiments, the wall thickness of the front connecting wall and the rear connecting wall is 0.5MM-1.5MM.
[0007] In one or more embodiments, the height of the front connecting wall and the rear connecting wall is 2MM-5MM.
[0008] In one or more embodiments, the tube body, the probe head and the tail cover are all made of copper material.
[0009] In one or more embodiments, the front end of the probe head has a needle-shaped probe end, the diameter of the probe end is 2.3MM-5.5MM, and the length of the probe end is 2CM-5CM.
[0010] In one or more embodiments, the diameter of the probe head increases gradually from the front end to the rear end, and the outer wall of the rear end of the probe head is flush with the outer wall of the tube body.
[0011] The beneficial effects of the utility model are as follows: the probe rod is composed of a probe head, a tube body and a tail cover. When installing, the tail cover is first fixed to the tail of the probe head for sealing, and then kerosene is poured into the tube body. The probe head is then covered on the front end of the tube body and welded to seal. The structure can prevent kerosene from spilling and is convenient for pouring kerosene. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is an exploded view of the probe rod according to an embodiment of the utility model;
[0013] Figure 2 This is an assembly diagram of the probe rod according to an embodiment of the utility model. DETAILED DESCRIPTION
[0014] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.
[0015] Please see attached Figure 1-2 The utility model provides a thermostat probe rod structure, which includes a tube body 1, a probe head 2 and a tail cover 3. The interior of the tube body 1 is a hollow structure. The rear end of the probe head 2 has an annular front connecting wall 4 connected to the front end of the tube body 1. The front connecting wall 4 is inserted into the tube body 1 and fits with the inner wall of the tube body to enhance the sealing performance. The connection between the probe head 2 and the tube body 1 is fixed by welding. The front end of the tail cover 3 has an annular rear connecting wall 5 connected to the rear end of the tube body. The rear connecting wall 5 is inserted into the tube body 1 and fits with the inner wall of the tube body to enhance the sealing performance. The connection between the tail cover 3 and the tube body 1 is fixed by welding. During production, the tail cover is first fixed to the tail of the probe head for sealing, and then kerosene is poured into the tube body. The probe head is then covered on the front end of the tube body and welded and sealed. The structure can prevent kerosene from spilling and is convenient for pouring kerosene.
[0016] The wall thickness of the front connecting wall 4 and the rear connecting wall 5 is 0.5MM-1.5MM, preferably 1MM, to ensure that the front connecting wall 4 and the rear connecting wall 5 have a certain structural strength. The height of the front connecting wall 4 and the rear connecting wall 5 is 2MM-5MM, preferably 3MM and 4MM, to ensure that the front connecting wall and the rear connecting wall have a certain insertion depth when inserted into the tube body, so that the structure is more stable after the three are connected, and the sealing is also better.
[0017] The tube body 1, the probe head 2 and the tail cover 3 are all made of copper material, which has good thermal conductivity and is easily available on the market.
[0018] The front end of the probe head 2 has a needle-shaped probe end 21, the diameter of the probe end is 2.3MM-5.5MM, the length of the probe end is 2CM-5CM, preferably the diameter is 3.5MM, and the length is 3.5MM.
[0019] The circular diameter of the probe head 2 gradually increases from the front end to the rear end, and the outer wall of the rear end of the probe head 2 is flush with the outer wall of the tube body 1, ensuring a smooth transition between the probe head and the tube body without ups and downs, so as to facilitate insertion into the object to be detected during use.
[0020] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
