Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

Referring to fig. 1 to 9, a steam release structure for a cup cover comprises a cover body 100, a sealing plug 300 and a silica gel pressure lever 400; the top of the cover body 100 is provided with a steam release chamber 110, the bottom of the steam release chamber 110 is provided with a steam release hole 112, a collar plate 111 is arranged in the steam release chamber 110, the steam release hole 112 is positioned in the collar plate 111, a sealing plug 300 is arranged in the collar plate 111, the steam release hole 112 is sealed by the sealing plug 300, a silica gel pressure lever 400 is arranged above the sealing plug 300, a pressure foot 410 at the bottom of the silica gel pressure lever 400 is pressed on the top of the sealing plug 300, the top of the silica gel pressure lever 400 is tightly propped against a pressure cover 200, the pressure cover 200 is arranged at the opening at the top of the steam release chamber 110, the pressure foot 410 is deformed by pressing down the pressure cover 200, the pressure of the silica gel pressure lever 400 on the sealing plug 300 is reduced, the steam passes through the steam release hole 112 to act an upward force on the sealing plug 300, the sealing plug 300 is jacked up, the steam is released, when the downward pressure on the pressure cover 200 is released, the pressure foot 410 is restored, the silica gel, Good sealing effect and long service life.

The sealing performance is ensured, the sealing ring 500 is arranged in the ring plate 111, the sealing plug 300 is arranged in the sealing ring 500, and the sealing ring 500 prevents steam from overflowing through a gap between the sealing plug 300 and the ring plate 111.

The section of the sealing plug 300 is in an inverted trapezoid shape, so that after the sealing plug 300 is inserted into the sealing ring 500, the sealing ring 500 is pressed against the inner wall of the ring plate 111 after being extruded by the sealing plug 300, and the sealing performance is further improved.

An annular groove 310 is formed in the top of the sealing plug 300, and a pressing foot 410 is inserted into the annular groove 310, so that the pressing foot 410 always presses the sealing plug 300.

Because the steam release hole 112 makes the stress area of the bottom of the sealing plug 300 smaller, the sealing plug 300 cannot be jacked up by steam, therefore, the periphery of the steam release hole 112 is provided with the convex ring block 113, the convex ring block 113 is positioned at the bottom of the sealing plug 300, a space which can allow steam to enter is formed between the bottom of the sealing plug 300 and the bottom of the steam release chamber 110, and after the presser foot 410 is deformed by stress, the steam in the space can jack up the sealing plug 300; while avoiding over-tight insertion of the sealing plug 300 into the sealing ring 500.

In order to fix the silica gel pressure lever 400 conveniently, the bottom of the pressing cover 200 is provided with an inserting position 210 for inserting the silica gel pressure lever 400, and a pressing block 211 pressing the top end of the silica gel pressure lever 400 is arranged in the inserting position 210.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
