[0023] The preferred embodiments of the utility model will be described in detail below with reference to the drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive, exemplary, and should not be interpreted as limiting the scope of protection of the utility model.

[0024] It should be noted that: similar reference numerals represent similar items in the following drawings, so once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0025] Figures 1-4 As shown, a silica gel air release valve, including valve body, valve body including air release sleeve 2 and the mounting plate 1 of air release sleeve 2 outside, air release sleeve 2 is equipped with the annular clamping groove 5 convenient for mounting plate 1 card.

[0026] Figures 1-4 As shown, therefore, when installing air release sleeve 2, mounting plate 1 is installed on the pressure cooker, this design plays the role of facilitating the installation of air release sleeve 2, and the annular clamping groove 5 can facilitate the assembly of air release sleeve 2 and mounting plate 1.

[0027] Figures 1-4 As shown, air release sleeve 2 is provided with a partition piece 10, the space in air release sleeve 2 is divided into a movable cavity 9 and a containing cavity 8 above the movable cavity 9 by the partition piece 10, the partition piece 10 is provided with a through hole 11 communicating the movable cavity 9 and the containing cavity 8, the movable cavity 9 is provided with an air release ball 6, when air release, air release ball 6 enters the containing cavity 8 through the through hole 11 due to pressure, the top surface of air release sleeve 2 is provided with a plurality of gas outlets 3 communicating with the containing cavity 8.

[0028] Figures 1-4As shown, when the pressure cooker is deflated, the pressure inside the pressure cooker is greater than the external pressure, so the deflation ball 6 is pushed by the pressure to pass through the through hole 11 on the partition sheet 10 from the movable cavity 9 to the containing cavity 8, and forms abutment with the inner top surface of the containing cavity 8. At this time, the opening of the deflation sleeve 2 communicates with the through hole 11, the gas in the pressure cooker is discharged through the opening, the through hole 11 and the gas outlet 3, and the deflation ball 6 is a steel ball, which is convenient and saves materials in manufacturing, thereby reducing the manufacturing cost.

[0029] Figures 1-4 As shown, the deflation sleeve 2 and the partition sheet 10 are integrally formed, which can facilitate manufacturing, and the partition sheet 10 and the deflation sleeve 2 are both elastic, and the deflation sleeve 2 is made of food-grade silica gel.

[0030] Figures 1-4 As shown, when the deflation ball 6 passes through the through hole 11, the partition sheet 10 deforms, thereby facilitating the movement of the deflation ball 6, and the food-grade silica gel is more resistant to high temperature and suitable for pressure cookers.

[0031] Figures 1-4 As shown, a pressing opening 4 is provided on the top surface of the deflation sleeve 2 and communicates with the containing cavity 8. After deflation is completed, an external object can be inserted into the containing cavity 8 through the pressing opening 4 and push the deflation ball 6 into the movable cavity 9, thereby facilitating the next use. This design facilitates the resetting of the deflation ball 6.

[0032] Figures 1-4 As shown, the plurality of gas outlets 3 are arranged in a ring around the pressing opening 4 as the center. Therefore, when the deflation ball 6 abuts against the inner top surface of the containing cavity 8, the pressing opening 4 is blocked while the gas outlets 3 remain unblocked. This design can effectively prevent the gas outlets 3 from being blocked by the deflation ball 6.

[0033] Figures 1-4 As shown, the inner wall of the containing cavity 8 at the pressing opening 4 is provided with an arc surface 7. When the deflation ball 6 abuts against the inner top surface of the containing cavity 8, the deflation ball 6 abuts against the arc surface 7 and is clamped at the pressing opening 4. This design not only makes the deflation ball 6 fit the pressing opening 4 better, but also prevents the deflation ball 6 from rolling and blocking the gas outlets 3 during deflation, thereby achieving the positioning effect.

[0034] Figures 1-5 As shown, the diameters of the pressing opening 4, the through hole 11 and the gas outlet 3 are all smaller than the diameter of the deflation ball 6. The diameters of the pressing opening 4 and the gas outlet 3 being smaller than the diameter of the deflation ball 6 can prevent the deflation ball 6 from being separated from the deflation sleeve 2 under the push of the pressure.

[0035] ​As shown, the thickness of the air outlet 3 and the air release sleeve 2 at the pressing opening 4 is greater than the thickness of the partition sheet 10, which can further avoid the air release ball 6 from separating from the air release sleeve 2 under the pressure pushing, and the pressing opening 4 extends downward along the inner wall of the accommodating cavity 8, which can play a role in guiding the gas into the air outlet 3.

[0036] Working principle: before use, the air release ball 6 is located in the movable cavity 9 at this time, as the pressure in the pressure cooker increases, the air release ball 6 enters the accommodating cavity 8 through the through hole 11 on the partition sheet 10 due to the pressure, and is attached to the arc surface 7, at this time, the gas is discharged through the air outlet 3, and as the gas is gradually discharged, the pressure in the pressure cooker decreases, the air release ball 6 gradually falls until it falls on the partition sheet 10 and blocks the through hole 11 to complete the air release, before use again, the air release ball 6 is re-entered into the movable cavity 9 by pressing.

[0037] The above describes a silica gel air release valve provided by the utility model, specific examples are applied in the text to describe the principle and implementation mode of the utility model, and the above embodiment is only used for helping to understand the utility model and the core idea. It should be pointed out that for ordinary skilled persons in the technical field, the utility model can be improved and modified in several ways without departing from the principle of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claim.
