Description

Technical Field

[0001] This utility model relates to the technical field of double-lid double-seal storage tanks, and in particular to a double-lid double-seal storage tank. Background Technology

[0002] A double-lid, double-seal storage tank is a type of storage tank with a double-sealing structure designed to improve the sealing performance and safety of the tank. This type of tank contains two lids and two sealing mechanisms to ensure that the stored contents do not come into contact with the outside air, thereby reducing the risk of spoilage. This design helps to seal the tank and ensure the integrity of the stored substances.

[0003] Traditional water-sealed containers (such as kimchi jars) involve filling a water tank with water after covering the container with a lid, thus isolating the internal environment of the container from the outside world to achieve a sealed storage effect. Although this method is simple and easy to implement, it has a significant drawback: the water inside the water tank is in contact with the outside, and the water in the water tank is prone to gradual evaporation. It will evaporate completely in a short time, and water must be added again. If water is not added after evaporation, the water-sealed lid loses its sealing function, and the stored food inside the water-sealed container will rot and spoil, resulting in losses. In order to solve this technical problem, this utility model proposes a double-lid, double-sealed storage tank. Utility Model Content

[0004] The main objective of this invention is to provide a double-lid, double-seal storage tank that can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A double-lid, double-seal storage tank includes a tank body, an airtight lid, a watertight lid, and a water storage tank. The tank body is integrally molded from ceramic (or glass) material and has a hollow interior. The water storage tank is positioned above the tank body and is in contact with the inner wall of the watertight lid. The inner surface of the airtight lid is in contact with the outer surface of the water storage tank, and the airtight lid is positioned above the watertight lid. The bottom of the water storage tank has a water outlet hole, and a water outlet pipe is connected to the water outlet hole and communicates with the interior of the water storage tank. A valve is installed on the outside of the water outlet pipe.

[0007] Preferably, the inner surface of the airtight cover and the outer surface of the water storage tank are both polished together, and the effective contact between the two polished surfaces can achieve a good airtight effect.

[0008] Preferably, the airtight cover has a sealing groove on its inner side, and a sealing gasket is connected to the inner wall of the sealing groove. The outer surface of the sealing gasket is in contact with the top of the tank, and the sealing gasket is made of rubber.

[0009] Preferably, the bottom of the tank is provided with a fixing groove, and the inner wall of the fixing groove is connected with a buffer pad, which is made of rubber.

[0010] Preferably, a handle is connected to the outer surface of the airtight cover, and the handle is located at the center of the airtight cover.

[0011] Preferably, the outer surface of the airtight cover is connected to a plurality of bases, and the inner walls of the plurality of bases are rotatably connected to lead screws.

[0012] Preferably, a positioning plate is connected to the outer surface of the lead screw, the outer surface of the positioning plate is rotatably connected to the outer surface of the base, and a handle is connected to the top end of the lead screw.

[0013] Preferably, the outer surface of the tank is connected with the same number of threaded seats as the base, and the inner wall of the threaded seat is threadedly connected to the outer surface of the lead screw.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In this invention, the watertight cover, watertight cover, and water storage tank work together to provide water storage. After the watertight cover is placed at the opening of the tank, the water inside the water storage tank seals the gap between the watertight cover and the tank, preventing air from entering the tank and creating an independent space inside the tank. The airtight cover covers the water storage tank, and the two pairs of polished surfaces are in effective contact, thus preventing the water inside the water storage tank from contacting the outside, reducing water evaporation, and increasing the water's lifespan.

[0016] In this invention, the water storage tank, the water outlet pipe, and the valve work together to drain the water from the storage tank. When it is necessary to drain the water from the storage tank, the water outlet pipe guides the water in the storage tank, and the valve is opened to open the water outlet pipe, which facilitates the drainage of the water from the storage tank. The valve has the function of opening and closing the water outlet pipe. When storing water in the storage tank, the valve is closed to prevent the water from flowing out of the storage tank.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1-5 As shown, a double-lid, double-seal storage tank includes a tank body 1, an airtight cover 2, a watertight cover 3, and a water storage tank 4. The tank body 1 is integrally molded from ceramic (or glass) material and has a hollow interior. The hollow interior of the tank body 1 serves as a storage space for storing items. The water storage tank 4 is located above the tank body 1, providing space for the tank body 1 to hold water. The water storage tank 4 is in contact with the inner wall of the watertight cover 3, which covers the opening of the tank body 1. Water is then injected into the water storage tank 4 to form the first layer of seal.

[0025] The airtight cover 2 is in contact with the outer surface of the tank body 1, and the airtight cover 2 is located above the watertight cover 3. The outside of the water storage tank 4 is covered by the airtight cover 2. The two pairs of grinding surfaces are tightly sealed, effectively preventing the evaporation of water inside the water storage tank 4, forming a second sealing layer. The airtight cover 2 reduces water evaporation and increases the water sealing time.

[0026] The water storage tank 4 has a water outlet at the bottom, and a water outlet pipe 5 is connected to the water outlet. The water outlet pipe 5 is connected to the inside of the water storage tank 4, and a valve 6 is installed on the outside of the water outlet pipe 5. When it is necessary to open the tank 1, the water inside the water storage tank 4 is discharged through the water outlet pipe 5, which facilitates the discharge of water from the water storage tank 4. The valve 6 has the function of opening and closing the water outlet pipe 5. A small opening is made at the bottom of the water storage tank 4, and then the water outlet pipe 5 and the valve 6 are connected. When cleaning is required, the water in the water storage tank 4 is automatically discharged by opening the valve 6, which facilitates the cleaning of the tank 1. At the same time, when the watertight cap 3 is removed, water is prevented from falling into the tank 1, preventing the contents of the tank 1 from being contaminated by water.

[0027] A fixing groove 9 is provided at the bottom of the tank body 1. A buffer pad 10 is connected to the inner wall of the fixing groove 9. The buffer pad 10 is made of rubber. The fixing groove 9 increases the stability of the buffer pad 10 and prevents the buffer pad 10 from detaching from the tank body 1. The tank body 1 is protected by contacting the object through the buffer pad 10 to prevent the tank body 1 from being bumped. The rubber buffer pad 10 has good extensibility and plays an elastic cushioning role, reducing the contact force between the tank body 1 and the object.

[0028] A handle 11 is connected to the outer surface of the airtight cover 2, and the handle 11 is located at the center of the airtight cover 2. The handle 11 increases the contact area between the airtight cover 2 and the hand, making it easier to pick up the airtight cover 2.

[0029] The inner side of the airtight cover 2 is provided with a shock-absorbing groove 7, and the inner wall of the shock-absorbing groove 7 is connected to a shock-absorbing pad 8. The outer surface of the shock-absorbing pad 8 is in contact with the top of the tank body 1, and the shock-absorbing pad 8 is made of rubber. The shock-absorbing pad 8 can fill the gap between the airtight cover 2 and the tank body 1, achieving a better sealing effect. Multiple bases 12 are connected to the outer surface of the airtight cover 2. The inner wall of each of the multiple bases 12 is rotatably connected to a lead screw 13. The bases 12 provide support for the lead screw 13 and transmit the pressure generated by the lead screw 13 to the airtight cover 2. The outer surface of the lead screw 13 is connected to a positioning piece 14, which restricts the position of the lead screw 13 and prevents it from moving after rotation. The outer surface of the positioning piece 14 is in contact with the bottom. The outer surface of the base 12 is rotatably connected, and the top of the lead screw 13 is connected to a handle 15. The handle 15 increases the contact area between the lead screw 13 and the hand, making it easier to rotate. The outer surface of the tank 1 is connected to the same number of threaded seats 16 as the base 12. The inner wall of the threaded seats 16 is threadedly connected to the outer surface of the lead screw 13. After the lead screw 13 rotates, it is supported by the threaded seats 16. The threaded seats 16 exert a pulling force on the lead screw 13, causing the lead screw 13 to apply pressure to the base 12. The base 12 transmits the pressure to the airtight cover 2, causing the airtight cover 2 to move downward. At the same time as the airtight cover 2 moves, it applies pressure to the shock-absorbing pad 8, causing the shock-absorbing pad 8 to seal the gap between the airtight cover 2 and the tank 1, further improving the sealing effect. Another effect of the shock-absorbing pad 8 is that when the airtight cover 2 is placed on the storage tank 1, it effectively reduces hard contact and avoids damage.

[0030] It should be noted that in actual use, the device first places the storage container into the tank 1, then fills the water tank 4 with water, then places the watertight cap 3 at the opening of the tank 1, and then places the airtight cap 2 on top of the tank 1. Next, the screw 13 is rotated by the handle 15. As the screw 13 rotates, the distance between the airtight cap 2 and the tank 1 decreases. Simultaneously, the movement of the airtight cap 2 applies pressure to the shock-absorbing pad 8, compressing it to seal the gap between the airtight cap 2 and the tank 1, thus improving the sealing effect of the airtight cap 2. Another effect of the shock-absorbing pad 8 is that it effectively reduces hard impact when the airtight cap 2 is placed on the storage container 1, preventing damage. The above describes the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
