[0002] At present, in order to prevent dry burning, some heaters have a temperature measurement function, but the temperature measurement is inaccurate and the reliability is low, and it cannot effectively prevent the occurrence of dry burning. For example, the temperature measurement of an induction cooker is generally performed by a temperature sensor installed on the lower surface of a microcrystalline ceramic plate to sense the temperature of the pot body. The microcrystalline ceramic plate has poor thermal conductivity, so the temperature measurement of the induction cooker is inaccurate and has low reliability. Utility Model Content
[0003] The utility model aims to provide a dry-burning prevention mechanism and a cookware, so as to alleviate the technical problems of inaccurate dry-burning detection and poor reliability of the existing cookware.
[0004] In a first aspect, the utility model provides an anti-dry burning mechanism, comprising:
[0005] A pressure container, wherein an elastic diaphragm is arranged inside the pressure container, and the elastic diaphragm divides the inside of the pressure container into a first cavity and a second cavity, wherein the first cavity contains a medium that changes volume at a critical temperature; and an air outlet connected to the second cavity is arranged on the outer wall of the pressure container;
[0006] A pressure relief valve, the pressure relief valve is connected to the air outlet;
[0007] An air whistle is connected to the pressure relief port of the pressure relief valve.
[0008] Furthermore, the critical temperature is the temperature of the pressure vessel when it is dry-burned.
[0009] Furthermore, the air horn is detachably connected to the pressure relief valve.
[0010] Furthermore, the air horn is connected to the pressure relief valve by threading, plugging or magnetic attraction.
[0011] Furthermore, the area of one end of the second cavity connected to the elastic diaphragm is larger than the area of the air outlet.
[0012] Furthermore, the medium for changing the volume is liquid.
[0013] In a second aspect, the utility model provides a cooker comprising a pot body and the above-mentioned anti-dry-burning mechanism.
[0014] Furthermore, a receiving cavity is provided inside the pot body, and the pressure-bearing container is located in the receiving cavity;
[0015] The outer wall of the pot body is provided with a through hole communicating with the accommodating cavity and the outside, and the air whistle is arranged at the through hole.
[0016] Furthermore, the outer end surface of the air whistle is flush with the outer wall of the pot body.
[0017] Furthermore, the through hole is arranged on the side facing away from the handle.
[0018] The utility model has at least the following advantages or beneficial effects:
[0019] The anti-dry burning mechanism provided by the utility model comprises: a pressure container, a pressure relief valve and an air whistle, wherein an elastic diaphragm is arranged inside the pressure container, the elastic diaphragm divides the inside of the pressure container into a first cavity and a second cavity, the first cavity contains a medium whose volume changes when a critical temperature is reached; an air outlet connected to the second cavity is arranged on the outer wall of the pressure container; the pressure relief valve is connected to the air outlet; and the air whistle is connected to the pressure relief port of the pressure relief valve.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0032] like Figure 1 and Figure 2 As shown, the anti-dry-burning mechanism 100 provided by the present invention is arranged inside the cooker.
[0033] The anti-dry burning mechanism 100 includes: a pressure container, a pressure relief valve 200 and an air whistle 300. An elastic diaphragm 130 is arranged inside the pressure container. The elastic diaphragm 130 divides the inside of the pressure container into a first cavity 110 and a second cavity 120. The first cavity 110 contains a medium that changes volume at a critical temperature. The medium can be gas, liquid, or solid. This application takes liquid as an example, wherein the critical temperature can be the temperature when the pressure container is dry-burned. The first cavity 110 is located inside the bottom surface of the pot body 400; the outer wall of the pressure container is provided with an air outlet connected to the second cavity 120; the pressure relief valve 200 is connected to the air outlet; and the air whistle 300 is connected to the pressure relief port of the pressure relief valve 200.
[0034] When the cookware is dry-burned, the temperature of the liquid in the first cavity 110 rises rapidly, causing the pressure in the first cavity 110 to rise rapidly, and the elastic diaphragm 130 bulges toward the second cavity 120, causing the air pressure in the second cavity 120 to rise. When the pressure exceeds the critical value of the pressure relief valve 200, the pressure relief valve 200 discharges the gas in the second cavity 120, and the gas flowing through the air whistle 300 causes the air whistle 300 to sound, thereby alerting the user. Since the anti-dry-burning mechanism 100 is located inside the cookware, it can directly respond to the temperature of the cookware, respond quickly, and is safe and reliable.
[0035] The first cavity 110 is flat and roughly circular in shape, and is disposed in the middle of the pot body 400 , so as to evenly conduct heat with the pot body 400 .
[0036] The air whistle 300 and the pressure relief valve 200 may be detachably connected. In certain situations where high-temperature cooking is required, the air whistle 300 may be removed to prevent the air whistle 300 from sounding and affecting the user's cooking.
[0037] Specifically, the air whistle 300 and the pressure relief valve 200 can be connected by threads, with an external thread provided on the outer wall of the pressure relief port, and a corresponding internal thread provided at the interface of the air whistle 300, and the connection is achieved by rotating the air whistle 300. Alternatively, the pressure relief port is directly plugged into the interface of the air whistle 300, or magnets are provided at both the air whistle 300 and the pressure relief port to connect the two by magnetic attraction.
[0038] The area of one end of the second cavity 120 connected to the elastic diaphragm 130 is larger than the area of the air outlet, so that the elastic diaphragm 130 has a certain area. After deformation, the part protruding toward the second cavity 120 is larger, thereby improving the sensitivity of the induction.
[0039] The cookware provided by the present invention comprises a cooker body 400 and the above-mentioned anti-dry-burning mechanism 100. Since the cookware provided by the present invention adopts the above-mentioned anti-dry-burning mechanism 100, the cookware provided by the present invention also has the advantages of the anti-dry-burning mechanism 100.
[0040] The pot body 400 is provided with a containing cavity inside, and the pressure container is located in the containing cavity; the outer wall of the pot body 400 is provided with a through hole connecting the containing cavity and the outside, and the air whistle 300 is arranged at the through hole.
[0041] In one feasible solution, the air whistle 300 can be exposed on the outside of the pot body 400, which is convenient for disassembly of the air whistle 300. In another feasible solution, the outer end surface of the air whistle 300 is flush with the outer wall of the pot body 400, and the overall consistency of the pot body 400 is better and more beautiful.
[0042] In another feasible solution, the through hole may be arranged on the side facing away from the handle to avoid interfering with the user's gripping of the handle.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
