Description

Technical Field

[0001] The utility model relates to a temperature detector applied to a gas stove. Background Art

[0002] The temperature probe is usually installed in the middle of the gas stove head. It detects the temperature by contacting the pot, and judges whether the pot is in a dry-burning state based on the detected temperature. When the pot is judged to be in a dry-burning state, the gas supply is cut off to solve the safety hazard. The temperature sensing part of the current temperature probe is exposed, which is easily affected by the surrounding heat when working, resulting in inaccurate temperature detection by the temperature sensing part.

[0015] 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.

[0016] Please see attached Figure 1-2 The utility model provides a temperature probe for gas stoves, which includes a housing 1, a temperature sensing part 2 and a windproof surrounding part 3. The temperature sensing part 2 is arranged on the inner side of the housing, and the top of the temperature sensing part 2 is the temperature sensing end. The windproof surrounding part 3 is arranged on the housing 1 and can be elastically extended up and down relative to the housing. The windproof surrounding part can be elastically extended downward to expose the temperature sensing end of the temperature sensing part. When the temperature probe is not in contact with the pot (such as Figure 1 As shown), the windproof enclosure surrounds the temperature sensing portion. When the temperature probe contacts the pot (as shown Figure 2 The weight of the pot presses on the windproof surrounding part to make it expand and contract downward until the bottom of the pot contacts the upper end surface of the temperature sensing part for temperature sensing. At the same time, the windproof surrounding part keeps surrounding the temperature sensing part under the action of elastic force, thereby playing a windproof role and preventing external heat from affecting the temperature sensing work of the temperature sensing part.

[0017] The windproof surrounding part 3 includes a fixed sleeve 31, a movable sleeve 32 and a telescopic spring 33. The movable sleeve 32 can move up and down relative to the fixed sleeve 31. The two ends of the telescopic spring 33 are used to respectively support the movable sleeve and the fixed sleeve. The fixed sleeve is installed on the outer shell 1. The movable sleeve moves up and down relative to the fixed sleeve, thereby exposing the temperature sensing end of the temperature sensing part. When the cookware is moved away, the movable sleeve loses the pressure of the cookware, and the telescopic spring pushes the movable sleeve up again.

[0018] A first limiting step 4 is provided on the inner side of the bottom of the movable sleeve 32, and a second limiting step 5 which can abut against the first limiting step is provided on the fixed sleeve 31. The second limiting step is arranged on the outer side of the fixed sleeve. With the cooperation of the first limiting step and the second limiting step, the movable sleeve can be prevented from separating from the limiting sleeve. The first limiting step and the movable sleeve are detachable structures.

[0019] There is a space between the movable sleeve 32 and the fixed sleeve 31 for installing the telescopic spring 33. The telescopic spring is hidden between the movable sleeve and the fixed sleeve to avoid the telescopic spring being exposed and affecting the appearance, and also to limit the position of the telescopic spring.

[0020] The top of the shell 1 is open, and the bottom of the fixing sleeve 31 is inserted into the opening. The fixing sleeve has a positioning convex step 6 that abuts against the shell. The windproof enclosure is installed with this structure, which has the advantages of easy installation and removal.

[0021] There is a gap between the inner wall of the shell 1 and the outer wall of the temperature sensing part 2. The shell 1 is provided with a ventilation structure 7, which is composed of two or more holes. The two or more holes form convection to facilitate the discharge and circulation of heat between the shell and the temperature sensing part, thereby avoiding internal heat accumulation affecting the temperature detection work of the temperature sensing part.

[0022] The temperature sensing part 2 includes an inner shell 21, an NTC 22 and a temperature sensing head 23, the temperature sensing head 23 is fixed to the top of the inner shell 21, the NTC 22 is arranged inside the inner shell 21 and contacts the temperature sensing head 23, and the bottom of the inner shell 21 is connected and fixed to the bottom of the outer shell 1, specifically by riveting or welding. Preferably, two or more ventilation holes are arranged on the shell wall of the inner shell, and the two or more ventilation holes form convection to discharge the heat inside the inner shell, so as to avoid the heat accumulation affecting the temperature detection work of the temperature sensing part.

[0023] 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.
