Detailed Description

In order to make the technical solution of the present invention clearer, the present invention will be described in detail with reference to fig. 1 to 11. It should be understood that the detailed description and specific examples, while indicating the scope of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.

The invention relates to a press type mute pressure release quick-opening cup cover which comprises a cup body 9 and a cup cover, wherein the cup cover comprises an outer cover 1, a key 2, an inner cover 4 and a water sealing piece which are coaxially arranged; the upper part of the inner cover 4 is rotatably arranged in the outer cover 1 through a buckle structure, and the lower part of the inner cover 4 is in threaded connection with the cup opening of the cup body 9; the key 2 is axially and movably arranged in a cavity in the middle of the outer cover through a vertical guide structure; the water sealing piece is arranged at the lower end port of the inner cover 4, the middle part of the water sealing piece is provided with a pressure release hole 5-1, one end of a connecting rod 8 is in threaded connection with the key 2, and the other end of the connecting rod 8 sequentially penetrates through the middle part of the inner cover 4 and the pressure release hole 5-1 to be fixedly connected with a knob sheet 8-2 which is arranged below the water sealing piece and is provided with a switch pressure release hole 5-1 (the connecting rod 8 and the knob sheet 8-2 can also be of an integral structure); the lower part of the key 2 is inserted into the accommodating cavity at the upper end of the inner cover, and a return spring 3 is arranged between the key 2 and the inner cover 4; the inner wall of the accommodating cavity of the inner cover 4 is circumferentially provided with inner side teeth 4-1, the outer wall of the key 2 is circumferentially provided with outer side teeth 2-2, and when the key 2 is pressed to move downwards, the inner side teeth 4-1 are meshed with the outer side teeth 2-2; and one of the threads on the outer wall of the inner cover and the threads on the inner wall of the cup opening is point-shaped threads uniformly distributed along the circumference.

Preferably, the punctiform threads are formed by at least two discrete convex points.

As a further preference, the thread on the inner wall of the cup mouth is a point-shaped thread which is composed of four discrete salient points 9-1. The vertical guiding structure is composed of a convex block 1-1 on the outer cover 1 and a groove 2-1 on the key 2 matched with the convex block, the key 2 can move up and down in the outer cover 1 and can rotate along with the outer cover 1, and the joint of the upper end of the convex block 1-1 and the top surface of the outer cover 1 limits the upward moving position of the key 2. The buckle structure is formed by mutually matched lock hooks 1-2 and buckles 4-2, the lock hooks 1-2 and the buckles 4-2 are uniformly distributed along the circumference, specifically, the lock hooks 1-2 uniformly distributed along the circumference are arranged on the inner wall of the outer cover 1, the buckles 4-2 uniformly distributed along the circumference are arranged on the top edge of the inner cover 4, the lock hooks 1-2 are matched with the buckles 4-2, and the inner cover 4 can freely rotate in the outer cover 1. Guide posts are arranged at the center of the bottom of the key 2 and the center of the containing cavity of the inner cover 4, and two ends of the reset spring 3 are respectively sleeved on the two guide posts. The water sealing piece comprises a circular sealing seat 5 and a sealing ring 6 sleeved in a mounting groove at the lower part of the circular sealing seat 5; a small sealing ring 7 for plugging the pressure release hole 5-1 is clamped on the knob piece 8-2. In order to more conveniently rotate the outer cover 1 or lift the cup, a handle 1-3 can be arranged on the outer cover 1.

The inner cover 4 and the cup body 9 of the cup cover are matched, screwed and fixed through the threads 4-3 of the inner cover 4 and the salient points 9-1 of the point-shaped threads at the opening part of the cup body 9; when the cup cover is in a closed state, as shown in the attached figure 6, the key 2 is at the highest position under the action of the spring 3, and in this state, rotating the outer cover 1 only can drive the key 2 to rotate along with the outer cover 1, and cannot drive the inner cover 4 to rotate to open the cup cover, so that the cup cover is prevented from being opened mistakenly; referring to the attached figure 8, when the cup cover needs to be opened, the key 2 is pressed, the outer side teeth 2-2 of the key 2 are meshed with the inner side teeth 4-1 of the inner cover 4, referring to the attached figure 10-11, when the outer cover 1 is rotated, the inner cover 4 rotates along with the outer cover 1, and the cup cover is opened under the combined action of the threads 4-3 on the inner cover 4 and the four discrete salient points 9-1 on the cup body 9; the point-shaped threads formed by four discrete salient points 9-1 uniformly distributed along the circumference on the cup body 9 are matched with the threads 4-3 on the inner cover 4, so that the cup cover can be opened only by rotating the inner cover 4 by 60 degrees, the quick opening is realized, no water remains in the thread groove when drinking water and returning water, and the cup is convenient to clean and process; when the cup cover needs to be closed, the cup cover can be closed under the action of the threads 4-3 of the inner cover 4 and the salient points 9-1 of the cup body 9 only by pressing the key 2 to enable the outer side teeth 2-2 of the key 2 to be meshed with the inner side teeth 4-1 of the inner cover 4 and rotating the cup cover, and the cup cover is simple in structure and very convenient to operate. Because the matching of the pressure release hole 5-1 of the circular sealing seat 5 and the connecting rod 8 and the matching of the connecting rod 8 and the through hole in the middle of the inner cover 4 are clearance fit, the circular sealing seat 5 cannot rotate along with the inner cover 4 in the opening and closing process of the cup cover, and the resistance and the noise generated when the sealing ring 6 and the cup body 9 move relatively can be reduced. The arrangement of the knob sheet 8-2 which can open and close the pressure release hole 5-1 can release the pressure in the cup body (when the button 2 is pressed, the connecting rod 8 moves downwards against the elasticity of the return spring 3, the knob sheet 8-2 moves downwards along with the downward movement, and the pressure in the cup body can be released by opening the pressure release hole 5-1) to easily open the cup cover, the connecting rod 8 can be separated from the button 2 by rotating the knob sheet 8-2, the water sealing piece can be separated together with the knob sheet 8-2, and all parts and inner cavities of the cup cover can be washed, so that the inside of the cup cover can be cleaned.
