[0024] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0025] This embodiment provides a sealing device for a food ingredient mixing tank, including a shell 1, a cavity 12 inside the shell 1, an installation ring 11 fixedly installed on the outer arc wall of the shell 1 near the edge of the upper surface, an installation groove 111 symmetrically opened on the upper surface of the installation ring 11, and a slot 112 opened on the side wall of the installation groove 111. It also includes a cover 2, a plurality of connecting blocks 22 symmetrically fixedly installed on the lower surface edge of the cover 2, and a slot 222 fixedly installed on the side wall of the connecting block 22 near the lower surface edge. After the connecting blocks 22 are inserted into the installation groove 111, the slot 222 is rotated to the bottom of the slot 112 to increase the sealing between the shell 1 and the cover 2. The connecting blocks 22 on the lower surface of the cover 2 are inserted into the installation groove 111, so that the slot 222 is inserted into the installation groove 111. The cover 2 is rotated so that the slot 222 enters the slot 112, thus completing the sealing of the cavity 12. This reduces the number of operation steps during sealing and improves the operation efficiency. At the same time, the cover 2 is automatically pressed down during rotation to avoid manual alignment errors.

[0026] like Figure 1 , Figure 2 , Figure 3 As shown, a sealing groove b122 is provided on the upper surface of the housing 1. The sealing groove b122 has an annular structure. An inclined angle is provided at the opening of the sealing groove b122, which facilitates the insertion of the sealing ring b23 into the sealing groove b122.

[0027] like Figure 1 , Figure 4 , Figure 5 As shown, a sealing ring b23 is fixedly installed on the lower surface of the cover 2. The sealing ring b23 is a flexible material with a ring structure. The sealing ring b23 is aligned vertically with the sealing groove b122. The sealing ring b23 is inserted into the sealing groove b122. The sealing ring b23 is preferably made of flexible food-grade silicone to increase the sealing between the cover 2 and the shell 1.

[0028] like Figure 4 , Figure 5 As shown, a pressure block 24 is fixedly installed at the center of the lower surface of the cover 2. A sealing groove a241 is opened on the side wall of the pressure block 24. A crank 21 is fixedly installed at the center of the upper surface of the cover 2. Rotating the crank 21 will drive the cover 2 to rotate.

[0029] like Figure 1 , Figure 2 , Figure 3 As shown, the cavity 12 has an inclined angle at the opening, and a sealing ring a121 is fixedly installed on the side wall of the cavity 12 near the edge of the upper surface. The sealing ring a121 is made of flexible material and is snapped into the sealing groove a241. The sealing ring a121 is preferably made of flexible food-grade silicone. After the pressure block 24 is inserted into the cavity 12, the pressure block 24 squeezes the sealing ring a121 to compress it. When the sealing ring a121 is aligned with the sealing groove a241, the sealing ring a121 resets and snaps into the sealing groove a241. The tight insertion of the pressure block 24 and the side wall of the cavity 12 forms the first line of defense, blocking most of the liquid or powder leakage. After the sealing ring a121 is snapped into the sealing groove a241, an annular sealed space is formed. Even if the main seal fails slightly, the secondary seal can still intercept leakage and can withstand the impact of negative pressure, positive pressure or high viscosity materials.

[0030] like Figure 1 , Figure 2 , Figure 3 As shown, the slot 112 has an arc-shaped structure. The upper sidewall of the slot 112 is inclined downwards towards the side away from the mounting slot 111. The upper surface of the block 222 fits against the inclined surface of the upper sidewall of the slot 112. The arc-shaped structure of the slot 112 facilitates the rotation of the block 222 along the slot 112.

[0031] like Figure 1 , Figure 4 , Figure 5 As shown, the upper surface of the locking block 222 slopes downwards from the side of the locking groove 112 near the mounting groove 111 towards the inside of the locking groove 112. One side of the locking block 222 has an arc-shaped structure. The inclined surface of the upper surface of the locking block 222 fits against the inclined surface of the upper side wall of the locking groove 112. When the locking block 222 rotates towards the inside of the locking groove 112, it drives the cover 2 to move downwards. During the rotation, the mechanical action of the inclined surface continuously presses the cover 2 down, so that the sealing ring b23 is evenly stressed and fits against the sealing groove b122, increasing the sealing performance inside the cavity 12. At the same time, the inclined groove structure forms a self-locking effect, so it is not easy to loosen even if the shell 1 vibrates during operation. The pressing can be completed by rotating the cover 2 without additional tools, which greatly improves the operating efficiency and is especially suitable for food stirring processes that require frequent opening of the lid.

[0032] like Figure 1 , Figure 4 As shown, a fixing screw hole 221 is provided through the side wall of the connecting block 22. A fixing bolt is installed in the internal thread of the fixing screw hole 221. When the fixing screw in the fixing screw hole 221 is tightened, the fixing screw presses against the side wall of the housing 1 to fix the position of the cover 2.

[0033] In practical use, the connecting block 22 on the lower surface of the cover 2 is inserted into the mounting groove 111, so that the locking block 222 is inserted into the mounting groove 111. The sealing ring b23 on the lower surface of the cover 2 is aligned vertically with the sealing groove b122. The sealing ring b23 is inserted into the sealing groove b122. The sealing ring b23 is made of flexible material. A pressure block 24 is fixedly installed on the lower surface of the cover 2. A sealing groove a241 is opened on the side wall of the pressure block 24. A sealing ring a121 is fixedly installed on the side wall of the cavity 12 near the edge of the upper surface. The ring a121 is made of flexible material. When the housing 1 moves downward, the pressure block 24 is inserted into the cavity 12, and the sealing ring a121 is inserted into the sealing groove a241 to increase the sealing performance of the cavity 12. The tight insertion of the pressure block 24 into the side wall of the cavity 12 forms the first line of defense, blocking most of the liquid or powder leakage. After the sealing ring a121 is engaged in the sealing groove a241, it forms an annular sealed space. Even if the main seal fails slightly, the secondary seal can still intercept leakage and can withstand the impact of negative pressure, positive pressure or high viscosity materials. Rotating the handle 21 causes the cover 2 to rotate. The cover 2, through the connecting block 22, causes the locking block 222 to rotate into the slot 112. The inclined surface of the upper surface of the locking block 222 fits against the inclined surface of the upper side wall of the slot 112. When the locking block 222 rotates into the slot 112, it causes the cover 2 to move downward. During the rotation, the mechanical action of the inclined surface continuously presses the cover 2 down, so that the sealing ring b23 is evenly stressed and fits against the sealing groove b122, increasing the sealing performance inside the cavity 12. At the same time, the inclined groove structure forms a self-locking effect, so it is not easy to loosen even if the shell 1 vibrates during operation. The pressing can be completed by rotating the cover 2 without additional tools, which greatly improves the operating efficiency and is especially suitable for food stirring processes that require frequent opening of the lid. The inclined surface of the locking block 222 cooperates with the slot 112 and automatically presses down the cover 2 during rotation, avoiding manual alignment errors.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
