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.
