When the internal air pressure reaches a certain value, the pressure drives the floating stopper to move upwards and drives the sealing ring to move upwards at the same time, the interior is communicated with the outside through the through groove at the moment, so that air is exhausted, and the floating stopper moves downwards again until the air is exhausted; the reciprocating action enables the internal pressure to be constant, the heating temperature in the pot is higher, and the cooking effect is better.

Description

Technical Field

[0001] This utility model relates to the field of pot body exhaust, and in particular to a floating stop pressure valve structure. Background Technology

[0002] Most non-pressure cooker products on the market have open heating chambers, resulting in significant heat loss and cooking results that do not meet expectations. Utility Model Content

[0003] To solve the above problems, this technical solution provides a floating stop air pressure valve structure.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A floating stop air pressure valve structure includes a floating stop mounting base, the floating stop mounting base having a connecting part, the connecting part having a plurality of through grooves on its outer periphery for communicating with an exhaust valve, a floating stop being provided in the through hole of the connecting part, and a sealing ring being provided in contact with the floating stop on the floating stop mounting base. When the internal air pressure reaches a preset value, the sealing ring is forced to deform so that water vapor can be discharged.

[0006] In some embodiments, the sealing ring has a plurality of positioning portions passing through the float mount.

[0007] In some embodiments, the outer diameter of the upper section of the positioning part gradually decreases from top to bottom, and the lower section is the insertion part.

[0008] In some embodiments, the end face of the insertion portion is designed to be arc-shaped.

[0009] In some embodiments, a float cover detachably connected to the float mounting base is also included, the float cover also having a plurality of through slots.

[0010] In some embodiments, the outer wall of the float mounting base is provided with a plurality of snap-fit ​​steps, and the inner wall of the float cover is provided with a snap-fit ​​part that is rotatably assembled with the snap-fit ​​steps.

[0011] The beneficial effects of this application are:

[0012] In a static state, the float moves downwards, and the deformed part of the sealing ring also moves downwards due to gravity, forming a sealed environment to isolate the airflow between the inside and outside of the pot. When the internal air pressure reaches a certain level, the pressure drives the float to move upwards, simultaneously causing the deformed part of the sealing ring to move upwards. At this time, the inside is connected to the outside through the through groove, thus starting to exhaust gas. After the gas is exhausted, the float moves downwards again. This repeated action keeps the internal pressure constant, resulting in a higher heating temperature inside the pot and better cooking results. Attached Figure Description

[0018] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Please refer to Figure 1-4 As shown, a floating stop air pressure valve structure includes a floating stop mounting base 1, the floating stop mounting base 1 is provided with a connecting part 2, the connecting part 2 is provided with a plurality of through grooves 3 on its outer periphery for communicating with an exhaust valve 4, a floating stop 5 is provided in the through hole of the connecting part 2, and a sealing ring 6 is provided in the floating stop mounting base 1 to contact the floating stop 5. When the internal air pressure reaches a preset value, the sealing ring 6 is forced to deform so that water vapor can be discharged.

[0020] In a static state, the float moves downwards, and the deformed part of the sealing ring also moves downwards due to gravity, forming a sealed environment to isolate the airflow between the inside and outside of the pot. When the internal air pressure reaches a certain level, the pressure drives the float to move upwards, simultaneously causing the deformed part of the sealing ring to move upwards. At this time, the inside is connected to the outside through the through groove, thus starting to exhaust gas. After the gas is exhausted, the float moves downwards again. This repeated action keeps the internal pressure constant, resulting in a higher heating temperature inside the pot and better cooking results.

[0021] In this embodiment, the sealing ring 6 is provided with a plurality of positioning parts 7 passing through the floating mounting base 1 to limit the sealing ring so that the two sides of the sealing ring are fixed, and the middle part of the sealing ring is a deformable part that contacts the copy cover. Therefore, the deformable part can only move up and down.

[0022] In this embodiment, the outer diameter of the upper section of the positioning part 7 gradually decreases from top to bottom, and the lower section is the insertion part. Due to the design of the outer diameter, the positioning part and the hole have a certain friction force, and the through hole can be better sealed in the static state to prevent heat loss.

[0023] In this embodiment, the end face of the insertion part is designed with an arc shape, which has a guiding function during assembly and makes it easier to insert and assemble.

[0024] In this embodiment, a floating stop cover 8 is also included that is detachably connected to the floating stop mounting base 1. The floating stop cover 8 is also provided with multiple through slots 3, which makes assembly convenient.

[0025] In this embodiment, the outer wall of the floating stop mounting base 1 is provided with multiple snap-fit ​​steps 9, and the inner wall of the floating stop cover 8 is provided with a snap-fit ​​part 10 that is rotatably assembled with the snap-fit ​​steps 9. The snap-fit ​​part is accommodated in the steps, and then the assembly of the two can be completed by rotation, which is more efficient.

[0026] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
