[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The utility model provides a vacuum silicone sealing component, such as Figure 1-Figure 4 As shown, it includes a cover body 1, which is covered on the ceramic bowl 2. The cover body 1 is a ceramic structure. A vacuum groove 11 is arranged in the middle of the cover body 1, and a through hole is arranged in the middle of the vacuum groove 11. A vacuum is drawn by aligning the joint of the vacuum machine with the vacuum groove 11 of the cover body 1. A silicone valve body 3 is arranged inside the through hole. The silicone valve body 3 includes an upper cover plate 31, and a lower plug 32 is connected to the bottom of the upper cover plate 31. An inner cover silicone layer 4 is arranged on the inner surface of the cover body 1, and a vacuum channel 42 is arranged between the upper part of the inner cover silicone layer 4 and the inner surface of the cover body 1. An annular ventilation groove 311 is arranged on the outer side of the silicone valve body 3. By extracting the air in the vacuum channel 42, after the air is extracted, the ceramic bowl 2 and the cover body 1 will be tightly fitted together due to the negative pressure effect and are difficult to separate. Only by pulling the silicone valve body 3 upwards can the ventilation groove 311 be opened, thereby allowing external air to enter, so that the ceramic bowl 2 and the cover body 1 are opened.

[0023] In this embodiment, the middle portion of the inner cover silicone layer 4 and the lower plug 32 are an integrally formed structure, ensuring that the inner cover silicone layer 4 is not easily broken.

[0024] Specifically, a cavity 41 with an annular structure is provided on the top surface of the inner cover silicone layer 4 near the vacuum channel 42 to facilitate vacuuming and maintaining a negative pressure effect.

[0025] Furthermore, a limiting ring 12 is installed on the outer side of the cover body 1 , and the inner wall size of the limiting ring 12 is matched with the top outer wall size of the cover body 1 , so that the cover body 1 can be tightly buckled on the ceramic bowl 2 .

[0026] Furthermore, the upper end of the ventilation groove 311 is located below the bottom surface of the vacuum groove 11, and the lower end of the ventilation groove 311 is connected to the vacuum channel 42. When the upper cover plate 31 is attached to the cover body 1, the ventilation groove 311 remains sealed and airtight, achieving a good vacuum effect. The upper end of the ventilation groove 311 can be opened by pulling up the upper cover plate 31, thereby achieving the separation of the ceramic bowl 2 and the cover body 1.

[0027] Furthermore, a sealing ring 43 is installed on the top outer side of the inner cover silicone layer 4 to ensure the sealing effect and prevent external air from entering the ceramic bowl 2.

[0028] Furthermore, the lower plug 32 is a circular structure, and the diameter of the lower plug 32 is larger than the diameter of the opening in the middle of the vacuum groove 11, so that it can cover the opening in the middle of the vacuum groove 11 under the action of vacuum to ensure sealing.

[0029] Furthermore, the silicone valve body 3 is made of silicone material, the upper cover plate 31 is a circular structure, and the diameter of the upper cover plate 31 is larger than the opening diameter of the middle part of the vacuum groove 11 and smaller than the diameter of the vacuum groove 11 .

[0030] When the vacuum silicone sealing assembly of the utility model is used, the cover 1 is first covered on the ceramic bowl 2 to ensure that the limit ring 12 is tightly fitted with the edge of the ceramic bowl 2 to form a preliminary sealing environment. Then, the vacuum machine is aligned with the vacuum groove 11 on the cover 1 through the vacuum machine, and the vacuum machine is started to start extracting the air in the vacuum channel 42.

[0031] During the vacuuming process, as the air is continuously discharged, a negative pressure state is gradually formed inside the ceramic bowl 2, so that the ceramic bowl 2 and the cover 1 are tightly fitted together by the negative pressure effect, achieving efficient sealing. At this time, under the negative pressure, the lower plug 32 of the silicone valve body 3 tightly covers the opening in the middle of the vacuuming groove 11, further enhancing the sealing performance.

[0032] When the user needs to open the ceramic bowl 2, he only needs to pull up the upper cover plate 31 of the silicone valve body 3. As the upper cover plate 31 rises, the upper end of the venting groove 311 gradually opens, and the outside air enters the vacuum channel 42, thereby destroying the negative pressure state inside the ceramic bowl 2. At this time, the user can easily remove the cover body 1 from the ceramic bowl 2.

[0033] During the whole process, the inner cover surface silicone layer 4 and the sealing ring 43 thereon always keep close contact with the edge of the ceramic bowl 2, ensuring the stability and reliability of the sealing effect. At the same time, since the silicone material has good elasticity and durability, the vacuum silicone sealing assembly of the utility model can withstand multiple uses without being easily damaged.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
