[0024] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1
[0025] like Figure 1-5 As shown, a burner mixing chamber sealing detection device includes a base 1, an upper mold 2, and a lower mold 3. The base 1 is equipped with a pressure gauge 4, an inflation switch 5, and a buffer groove 6. The pressure gauge 4 is connected to the buffer groove 6. The inflation switch 5 is located on an inflation pipe 7 connected to the buffer groove 6. The bottom of the lower mold 3 has a recessed platform 11 placed on the buffer groove 6, and the top of the lower mold 3 has a groove 8. The bottom of the groove 8 is connected to the buffer groove 6 through an air hole 12. Bosses 9 are provided around the groove 8, and sealing rubber rings 10 are provided on the bosses 9 and the groove 8. The burner mixing chamber A is placed inside the groove 8 and contacts the sealing rubber rings 10 on the bosses 9 and the groove 8. The upper mold 2 is placed on the edge of the burner mixing chamber A and pressed tightly, forming a sealed cavity within the burner mixing chamber A, the lower mold 3, and the buffer groove 6. This allows for the detection of the air pressure in the sealed cavity, and the determination of whether the mixing chamber is leaking based on the pressure value. The device is easy to operate and has standardized specifications.
[0026] The recessed platform 11 is equipped with a sealing rubber ring 10. The sealing rubber ring 10 serves a sealing function, preventing air leakage at the connection under pressure and ensuring detection accuracy. The buffer groove 6 forms a buffer space to ensure the stability of gas entry and facilitate gas pressure detection. There are at least two air holes 12, and the sealing rubber ring 10 on the groove 8 does not cover the air holes 12. The two air holes 12 facilitate gas flow and reduce gas pressure fluctuations. Example 2
[0027] like Figure 1-4As shown, this embodiment is obtained by adding technical features such as the clearance opening 13 on the basis of embodiment one. The other technical features are the same as those in embodiment one. The similarities will not be repeated here. The difference between this embodiment and embodiment one is that the edge of the upper mold 2 at the boss 9 is provided with a clearance opening 13 that cooperates with the combustion chamber A.
[0028] In this embodiment, the clearance 13 cooperates with the outer edge of the burner, so that when the combustion chamber is placed flat on the upper mold 2, it also plays a limiting role, preventing the burner from deviating and affecting the sealing of the sealing rubber ring 10.
[0029] The overall technical solution formed by the above embodiments is used as follows:
[0030] The base 1 is fixed on the operating platform of the press. The upper mold 2 is set on the pressure piston of the press. The mixing chamber of the burner cover is covered on the upper mold 2 and contacts the sealing rubber rings 10 on the boss 9 and the groove 8 respectively. The protrusion on the edge of the burner mixing chamber A is inside the relief opening 13. Under the action of the pressure piston, the upper mold 2 moves downward and covers the edge of the burner mixing chamber A, increasing the pressure of the upper mold 2 and pressing the burner mixing chamber A tightly on the upper mold 2. At this time, the burner mixing chamber A forms a sealed chamber connected to the buffer groove 6 through the air hole 12. The sealed chamber is filled with air through the air filling switch 5. After reaching a certain air pressure, the air filling is stopped. The pressure value is observed through the pressure gauge 4 to determine whether the burner mixing chamber A is leaking.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments. Many other equivalent embodiments may be included without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
