Abstract
Description
Technical Field
[0001] The utility model relates to a temperature control probe for a stove.
Background Art
[0002] Gas stoves are common kitchen cooking appliances. They heat cookware by burning gas. At present, in order to improve the safety performance of gas stoves, a temperature control probe is set on the burner head of the gas stove. By means of the temperature control probe, the real-time temperature of the cookware is detected, so as to judge whether the cookware is in a dry burning state. When it is judged that the dry burning state occurs, a signal is sent to the solenoid valve of the gas stove to timely cut off the gas source and prevent fire accidents caused by dry burning. At present, the temperature control probes on the market also have the function of detecting the removal of the pot through a magnetic control switch. However, there are various types of burner heads on the market at present, and the structures of some burner heads do not support fixed installation with L-shaped probes, so the use of this type of temperature control probe is limited.
[0003] Therefore, it is necessary to make further improvements to it.

Specific Embodiments
[0015] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.
[0016] Please refer to Figure 1 , this application provides a temperature control probe for a stove, which includes a probe body, a vertical rod 1 and a fixing seat 2. The probe body is connected to the top of the vertical rod 1. The vertical rod passes through the fixing seat 2 and is telescopically connected to the fixing seat. The fixing seat 2 has an installation part 3 with a threaded connection structure 21, and is screwed to the reserved hole position on the stove head through the threaded connection structure on the installation part, so that the temperature control probe is fixed on the stove head. A magnetic block 4 and a reed switch 5 are respectively provided on the fixing seat 2. A magnetic shield 6 is provided on the vertical rod, and the magnetic shield is located between the magnetic block and the reed switch. Under normal conditions, the magnetic shield can shield the magnetic block from triggering the reed switch. When the probe body moves downward, the magnetic shield also moves downward, causing the magnetic block to trigger the reed switch. In this solution, the magnetic block and the reed switch are arranged on the fixing seat, making full use of the space of the fixing seat.
[0017] A telescopic cavity for inserting the vertical rod is provided inside the fixing seat 2. A spring member 7 that abuts against the vertical rod is provided in the telescopic cavity. The spring member is sleeved on the vertical rod 1. By arranging the spring member on the fixing seat, it can be away from heat radiation. Therefore, the heat resistance requirement for the spring is not so high, and a non-high-temperature-resistant spring within 250 °C can be selected for use, greatly reducing the use cost of the spring member, and thus reducing the manufacturing cost of the temperature control probe as a whole.
[0018] The bottom of the fixed seat 2 is provided with a sealing part 8 for opening the telescopic cavity. The sealing part is threadedly connected to the fixed seat. Setting the sealing part to close the telescopic cavity can prevent the spring element from loosening and also facilitate the replacement of the spring element during later maintenance. The sealing part 8 is provided with an avoidance hole through which the bottom of the vertical rod can pass. The cooperation between the vertical rod and the avoidance hole can prevent the vertical rod from shaking during telescoping.
[0019] Preferably, the signal line 9 of the probe body is arranged along the space inside the vertical rod 1, which can prevent the signal line from being exposed, has a certain protective effect on the signal line, and is more aesthetically pleasing.
[0020] The probe body includes a temperature sensing head 10, an NTC temperature sensing unit 11, and a heat insulation shell 12. The NTC temperature sensing unit is placed inside the temperature sensing head. The heat insulation shell 12 is sleeved on the side wall of the temperature sensing head 10 to achieve a heat insulation effect and prevent the hot air or flame on the side from affecting the temperature of the temperature sensing head. The temperature sensing head 10 is fixedly connected to the top of the vertical rod 1. Further, the temperature sensing head 10 is made of copper material, and the heat insulation shell 12 is made of stainless steel material. The copper material has a high thermal conductivity, so making the temperature sensing head of copper helps to more accurately monitor the temperature. The stainless steel material has a lower thermal conductivity, and even if it is heated by flame or heat radiation, it is not easy to affect the temperature sensing head due to its low thermal conductivity.
[0021] At the top position of the vertical rod 1, a housing 13 is provided. The probe body is located inside the housing and does not contact the housing. The top end of the temperature sensing head 10 is exposed at the top of the housing 13. An insulating area is formed between the outer cover and the probe body. The air in the insulating area is an effective heat insulation barrier, which can prevent the heat of the outer cover from directly radiating onto the probe body.
[0022] The above is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the content disclosed in the present invention shall be included in the protection scope recorded in the claims.
