Connecting pieces 101 are fixedly connected to the outer walls on both sides of the bowl body 1. Buckles 3 are rotatably arranged on the connecting pieces 101. A buckling groove is opened at the center of the top of the bowl cover 2. An air release port 201 distributed symmetrically is fixedly communicated with the top of the buckling groove. Buckling blocks are fixedly connected to both sides of the top of the buckling groove. The buckling blocks are clamped with the buckles 3, so that the buckles 3 seal the bowl cover 2 and the bowl body 1. A pressing button 4 is slidably arranged at the center of the top of the buckling groove. A partition layer is arranged in the bowl cover 2. An air release structure is arranged in the partition layer. The air release structure is slidably arranged in the air release port 201. Driving components distributed symmetrically are arranged in the partition layer. The pressing button 4 is pressed to drive the air release structure to slide by the driving components.
[0023] Please refer to Figure 2 and Figure 3 As shown in FIGS. and, the air release structure includes a plugging block 5 and a second push plate 501. A first sliding groove 203 is formed in the interlayer. A sliding block is fixedly connected to one side of the plugging block 5. The sliding block is slidably arranged in the first sliding groove 203. The second push plate 501 is fixedly connected to the bottom of the plugging block 5. A compression spring 6 is arranged at one end of the plugging block 5. The second push plate 501 at the bottom of the plugging block 5 drives the plugging block 5 to contract through the drive of the drive assembly. While contracting, the compression spring 6 is compressed. Thus, when the drive assembly releases the second push plate 501, the plugging block 5 rebounds and resets to its original position to block the air release port 201.
[0024] Please refer to Figure 3 and Figure 4 As shown in FIGS. and, a threaded head 401 is fixedly connected to the bottom of the push button 4. A drive block 13 is slidably arranged in the interlayer. A threaded groove is formed at the top of the drive block 13. The threaded groove is engaged with the threaded head 401. Symmetrically distributed slide rails 12 are fixedly connected to the inner wall of the interlayer. A first sliding bolt 1301 is slidably arranged in the slide rail 12. A downward pressure spring 14 is arranged at the bottom of one end of the first sliding bolt 1301 located in the slide rail 12. The other end of the first sliding bolt 1301 is fixedly connected to the drive block 13. After the push button 4 is used for a long time or is damaged, the threaded head 401 fixedly installed at its bottom can be disengaged from the drive block 13 by rotating the push button 4 body, so as to facilitate the user to replace the push button 4. The slide rails 12 are provided to limit the downward sliding angle of the drive block 13 and prevent the situation of downward sliding deviation.
[0025] Please refer to Figure 3 As shown in FIG., the drive assembly includes a pressure-receiving block 7, a connecting rod 8, a push rod 9, a movable rod 10 and a slider 11. The pressure-receiving blocks 7 are rotatably arranged in the interlayer and are symmetrically distributed. The connecting rod 8 is fixedly connected to one end of the pressure-receiving block 7. One end of the connecting rod 8 is movably provided with a push rod 9. Symmetrically distributed third sliding grooves are formed in the interlayer. The push rod 9 is slidably arranged in the third sliding grooves. Symmetrically distributed second sliding grooves 204 are formed in the interlayer. A slider 11 is slidably arranged on the second sliding grooves 204. A first push plate 1101 is fixedly connected to the top of the slider 11. The first push plate 1101 is in abutting contact with the second push plate 501. One end of the slider 11 is fixedly connected to a movable rod 10. The movable rod 10 is rotatably arranged on the inner wall of the interlayer, and the other end thereof is in abutting contact with the push rod 9. When the push button 4 is pressed down, the push button 4 drives the drive block 13 to press down the pressure-receiving block 7, so that the pressure-receiving block 7 rotates and drives the push rod 9 to push the movable rod 10. Subsequently, the movable rod 10 drives the slider 11 to slide. The first push plate 1101 arranged at the top of the slider 11 abuts against the second push plate 501 at the bottom of the plugging block 5, so that the plugging block 5 releases the blockage of the ventilation groove 205, and the hot air is discharged from the air release port 201.
[0026] Please refer toFigure 2 and Figure 3 On both sides of the inner wall of the bowl cover 2, ventilation grooves 205 are provided, and the ventilation grooves 205 communicate with one side inner wall of the air release port 201.
[0027] The specific operation process of this utility model is as follows: When the bowl cover 2 and the bowl body 1 are tightly clamped through the buckle 3 and the buckle block, the air release port 201 at the top of the bowl cover 2 is completely blocked by the blocking block 5 inside the bowl cover 2, ensuring the sealing performance inside the bowl body 1 and effectively preventing heat dissipation. At this time, the blocking block 5 keeps a non-contact state with the first push plate 1101 in the interlayer through the second push plate 501 at its bottom, and one end of the blocking block 5 is subjected to the pulling force of the contraction spring 6 to maintain its stable blocking position. When it is necessary to release the hot air inside the bowl body 1, the user presses the button 4 on the top of the bowl cover 2. The threaded head 401 at the bottom of the button 4 meshes with the threaded groove on the top of the driving block 13 in the interlayer, and the driving block 13 slides downward along the slide rail 12 under the downward pressure of the button 4. At the same time, the downward pressure of the driving block 13 causes the first sliding bolt 1301 connected to it to compress the downward pressure spring 14 and push the pressure-receiving block 7 to rotate. The rotation of the pressure-receiving block 7 drives the push rod 9 to slide in the third chute through the connecting rod 8, and the push rod 9 further pushes the movable rod 10. The other end of the movable rod 10 abuts against the slider 11, causing the slider 11 to slide in the second chute 204. The sliding of the slider 11 drives the first push plate 1101 at its top to approach the second push plate 501 at the bottom of the blocking block 5 and produce an abutting effect, thereby pushing the blocking block 5 to slide along the first chute 203 and compressing the contraction spring 6. During this process, the blocking block 5 gradually releases the blockage of the ventilation groove 205, enabling the hot air inside the bowl body 1 to be discharged through the ventilation groove 205 and the air release port 201. When the user stops pressing the button 4, the downward pressure spring 14 rebounds and pushes the first sliding bolt 1301 to drive the driving block 13 to move upward, and then drives the button 4 to rise and reset through the threaded head 401. At the same time, the contraction spring 6 also pushes the blocking block 5 to slide reversely along the first chute 203 until the ventilation groove 205 is blocked again, restoring the sealed state of the bowl body 1.
[0028] The above has made an exemplary description of the present utility model in conjunction with the drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
