Technical Field
[0001] The present application relates to the technical field of temperature sensors, and in particular to a gas stove temperature sensor with a fireproof cover. Background Art
[0002] As an indispensable cooking appliance in modern kitchens, the safety and reliability of gas stoves have always been a focus of attention. As people's expectations for quality of life continue to rise, the safety and performance of gas stoves have become a key concern for users. With technological advancements, people's safety requirements for gas stoves have also become more stringent. In recent years, with the popularization of smart home concepts and technological advances, gas stoves with temperature sensors have been introduced to the market. In particular, stoves with technological improvements in flame control and temperature monitoring have become a new favorite in the market, further enhancing the safety and ease of use of gas stoves and meeting users' demand for efficient and safe cooking. These technologies are of great significance in improving the safety, convenience, and intelligence of gas stoves.
[0003] Currently, the temperature sensor for measuring and preventing dry-burning in gas stoves is installed in the center of the stove burner. A heat collector plate, equipped with an NTC or thermocouple, rests against the bottom of the pot to sense the temperature. Overtemperature alarms are triggered, and the gas is shut off to prevent dry-burning accidents. During operation, the heat collector plate, located in the center of the stove burner, is exposed to the flame and heated. Because the flame temperature is significantly higher than the pot bottom, the measured temperature is not the actual temperature, leading to frequent temperature inaccuracies and false alarms. The high temperature can even damage the temperature-sensing element inside the heat collector plate, rendering the temperature sensor inoperable. Even with a fixed protective shield installed outside the heat collector plate, the curvature of the pot bottom can create gaps in the shield, preventing it from completely isolating the flame, or the shield can press against the pot bottom, preventing the heat collector plate from contacting the pot bottom. This can also lead to temperature inaccuracies, false alarms, and temperature sensor failure. Summary of the Invention
[0004] In order to solve the problem that the protective cover cannot completely isolate the flame due to the different curvatures of the pot bottom, or the protective cover presses against the heat collecting plate at the bottom of the pot and cannot contact the bottom of the pot, the purpose of this application is to provide a gas stove temperature sensor with a fireproof cover.
[0005] The gas stove temperature sensor with a fireproof cover provided in this application adopts the following technical solution:
[0006] A gas stove temperature sensor with a fireproof cover comprises:
[0007] The temperature measuring component includes a heat collecting plate, a first spring, a temperature sensing element, a mounting shaft and a support pipe. One end of the support pipe is connected to the heat collecting plate, and the other end is connected to the mounting shaft. The mounting shaft and the support pipe are connected by the first spring so that the support pipe can move relative to the mounting shaft. The temperature sensing element passes through the mounting shaft and the support pipe and is connected to the heat collecting plate;
[0008] The fireproof cover component is sleeved outside the temperature measuring component and includes a fireproof cover body, a second spring and a mounting member. The mounting member is connected to the support pipe, and the fireproof cover body is connected to the mounting member by the second spring so that the fireproof cover body can move relative to the mounting member.
[0009] By adopting the above technical solution, the heat collecting plate conducts the collected heat to the temperature sensing element to realize the temperature measuring function. The first spring acts on the support pipe, so that the heat collecting plate connected to the support pipe can be closely attached to the surface of the object to be measured. And the fireproof cover component is provided with a second spring, so that the fireproof cover body can move relative to the heat collecting plate. With the cooperation of the first spring and the second spring, when measuring a concave bottom of a pot, the second spring is compressed more, and when measuring a convex bottom of a pot, the first spring is compressed more. Thus, when measuring the temperature of pots with different arcs, the fireproof cover can be closely attached to the bottom of the pot, improving the applicability of the sensor.
[0010] Optionally, there is a gap between the fireproof cover body and the support pipe.
[0011] By adopting the above technical solution, the gap can block the heat from being conducted from the fireproof cover body to the support pipe, ensuring that the inside of the sensor does not need to bear a large high temperature.
[0012] Optionally, the first spring is arranged between the support pipe and the temperature sensing element, and both ends of the first spring are respectively connected to the heat collecting plate and the mounting shaft.
[0013] By adopting the above technical solution, the support pipe can protect the first spring from external interference, thus ensuring the stable operation of the first spring.
[0014] Optionally, the temperature measuring component further includes a limit ring. The limit ring is arranged outside the mounting shaft, and the support pipe has a limit portion, and the limit ring and the limit portion can form a snap connection.
[0015] By adopting the above technical solution, the snap connection formed by the limit ring and the limit portion can prevent the support pipe from falling off the mounting shaft, thus ensuring the stable use of the sensor.
[0016] Optionally, a spring sleeve is arranged outside the mounting member, and the second spring is arranged between the spring sleeve and the mounting member.
[0017] By adopting the above technical solution, a connection method of the fireproof cover, by adding a spring sleeve, makes the installation of the second spring more stable, ensuring the stability of the temperature measuring process of the sensor.
[0018] Optionally, the mounting member is provided with a first liquid drain port.
[0019] By adopting the above technical solution, the first liquid drain port discharges the liquid when the liquid enters between the fireproof cover assembly and the detection assembly, avoiding the accumulation of liquid in the sensor.
[0020] Optionally, the second spring is sleeved outside the support pipe, and both ends of the second spring are respectively connected to the mounting member and the fireproof cover body.
[0021] By adopting the above technical solution, for another connection method of the fireproof cover assembly, the mounting member can be in a simple shape such as a ring. By sleeving the second spring outside the support pipe, the second spring acts stably. This structure is easy to install and is suitable for use when there is no need to bend the mounting shaft.
[0022] Optionally, the fireproof cover body is provided with a second liquid drain port.
[0023] By adopting the above technical solution, the second liquid drain port discharges the liquid when the liquid enters between the fireproof cover body and the support pipe, avoiding the accumulation of liquid in the sensor.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. The heat collecting plate conducts the collected heat to the temperature sensing element to achieve the temperature measurement function. The first spring acts on the support pipe, so that the heat collecting plate connected to the support pipe can be closely attached to the surface of the item to be measured. And the fireproof cover assembly is provided with a second spring, so that the fireproof cover body can move relative to the heat collecting plate. Under the cooperation of the first spring and the second spring, when measuring a concave pot bottom, the second spring is compressed more, and when measuring a convex pot bottom, the first spring is compressed more. Thus, when measuring the temperatures of pot bottoms with different arcs, the fireproof cover can be closely attached to the pot bottom, improving the applicability of the sensor;
[0026] 2. The gap can block the heat conduction from the protective cover body to the support pipe, ensuring that the inside of the sensor does not need to bear a large high temperature;
[0027] 3. The clamping connection formed by the limiting ring and the limiting part can prevent the support pipe from falling off the mounting shaft, thus ensuring the use stability of the sensor. Description of the Drawings

Detailed implementation manners
[0035] The following further describes the present application in detail with reference to the accompanying drawings.
[0036] Embodiment 1: A gas stove temperature sensor with a fire protection cover, referring to Figure 1 , Figure 2 and Figure 3 , including a temperature measurement component 1 and a fire protection cover component 2, wherein the temperature measurement component 1 can be closely attached to the bottom of the pot to measure the temperature of the bottom surface of the pot, and the fire protection cover component 2 can surround the temperature measurement component 1 to prevent the flame temperature from interfering with the temperature measurement of the temperature measurement component 1, enhance the accuracy of temperature monitoring, and can also improve the safety of the gas stove and extend the service life of the sensor. The temperature measurement component 1 includes a heat collecting plate 11, a first spring 12, a temperature sensing element 13, a mounting shaft 14, a support pipe 15 and a limiting ring 16. One end of the support pipe 15 is installed with the heat collecting plate 11, and the other end is connected to the mounting shaft 14. The first spring 12 is inside the support pipe 15, one end is connected to the heat collecting plate 11, and the other end is connected to the mounting shaft 14. The inner diameter of the support pipe 15 is slightly larger than the outer diameter of the mounting shaft 14, so that the support pipe 15 can be sleeved outside the mounting shaft 14 and move up and down relative to the mounting shaft 14. The temperature sensing element 13 passes through the mounting shaft 14 and the support pipe 15 and is connected to the heat collecting plate 11. By attaching the heat collecting plate 11 to the bottom of the pot to be measured for temperature, the temperature can be collected, enabling the temperature sensing element 13 to measure the temperature of the bottom surface of the pot.
[0037] Referring to Figure 4 , the part of the upper end of the mounting shaft 14 located inside the support pipe 15 is connected to the limiting ring 16, and the lower end of the support pipe 15 is a limiting part 17 that converges inward. The limiting ring 16 can form a snap connection with the limiting part 17 to prevent the support pipe 15 from detaching from the upper end of the mounting shaft 14, making the use of the sensor more stable.
[0038] Referring to Figure 3, two sets of fireproof cover assemblies 2 are sleeved outside the temperature measuring assembly 1, including a fireproof cover body 21, a second spring 22, a mounting member 23 and a spring sleeve 24. The mounting member 23 has a structure with a funnel-shaped lower end converging and an upper side expanding. The converging part at the lower side is connected to the support pipe 15, and the expanding part at the upper side is connected to the fireproof cover body 21 through the second spring 22, so that a gap is formed between the fireproof cover body 21 and the support pipe 15, which can isolate heat and prevent heat from affecting the internal components of the sensor. The spring sleeve 24 is arranged outside the upper side of the mounting member 23, and the second spring 22 is arranged between the spring sleeve 24 and the mounting member 23. The fireproof cover body 21 is connected to the second spring 22 between the mounting member 23 and the spring sleeve 24, so that the fireproof cover assembly 2 can be stably installed. A first liquid discharge port 25 is also opened at the converging end of the mounting member 23 for the liquid infiltrating into the sensor to flow out, thus preventing the liquid from accumulating in the sensor.
[0039] Embodiment 2: A gas stove temperature sensor with a fireproof cover, referring to Figure 5 and Figure 6 , compared with Embodiment 1, the difference in Embodiment 2 lies in the installation method of the fireproof cover assembly 2, and Embodiment 2 does not include the spring sleeve 24. The fireproof cover assembly 2 includes a fireproof cover body 21, a second spring 22 and a mounting member 23. The mounting member 23 is a ring structure sleeved outside the support pipe 15, and the second spring 22 is also sleeved outside the support pipe 15, and is connected to the mounting member 23 and the fireproof cover body 21 at both sides respectively. The fireproof cover body 21 is a funnel-shaped structure, and the converging end is connected to the second spring 22, so that the fireproof cover body 21 can move stably on the support pipe 15. A gap is formed between the expanding end of the fireproof cover body 21 and the support pipe 15, and the gap can isolate heat and prevent heat from affecting the internal components of the sensor. A second liquid discharge port 26 is also opened at the converging end of the fireproof cover body 21 for the liquid infiltrating into the sensor to flow out, thus preventing the liquid from accumulating in the sensor.
[0040] The implementation principle of this application is: by providing the first spring 12 and the second spring 22, the fireproof cover body 21 and the heat collecting plate 11 can move relatively back and forth, so that the sensor can be applied to the bottom of the pot with different arcs. When measuring the concave bottom of the pot, the second spring 22 is compressed more. When measuring the convex bottom of the pot, the first spring 12 is compressed more. Thus, when measuring the temperature of the bottom of the pot with different arcs, the fireproof cover can closely fit the bottom of the pot, improving the applicability of the sensor.
[0041] The embodiments of this specific implementation manner are all preferred embodiments of this application, and do not limit the protection scope of this application accordingly. The same components are represented by the same reference numerals. Therefore: All equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
