Abstract
Description
Technical Field
[0001] This utility model relates to the field of ceramic jar technology, specifically to a ceramic jar with moisture-proof function. Background Technology
[0002] Ceramic jars are commonly used to store food, medicine, tea, and other items, and are widely used in daily life and commerce. However, traditional ceramic jars have limited sealing performance, and moisture from the outside air can easily enter the jar, causing the stored items to become damp and deteriorate, affecting their quality and shelf life.
[0003] Although there are some sealed ceramic jars on the market, most of them only reduce the entry of moisture through a simple sealing structure, and cannot fundamentally eliminate the moisture inside the jar, so the moisture-proof effect is not good. Utility Model Content
[0004] In view of the problems existing in the current ceramic jars with moisture-proof function, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a ceramic jar with moisture-proof function, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A moisture-proof ceramic jar includes a jar body and a lid. The lid is threaded onto the upper part of the jar body. A fixed shell is provided on the top of the lid. A piston is slidably disposed inside the fixed shell. A pull rod is fixedly disposed on the upper side of the piston. The upper end of the pull rod extends to the outside of the fixed shell. A first through hole is provided at the bottom of the fixed shell. A second through hole is provided on the top of the lid at a position corresponding to the first through hole. A first gas one-way valve is fixedly disposed between the first and second through holes. An exhaust hole is provided on the lower front side of the fixed shell. A second gas one-way valve is fixedly disposed inside the exhaust hole. A limiting mechanism is provided on the top of the lid to restrict the movement of the fixed shell relative to the lid.
[0008] Preferably, the limiting mechanism includes a U-shaped rod and a sealing ring. The sealing ring is fixedly disposed on the upper surface of the cover, and the inner wall of the sealing ring abuts against the outer wall of the fixed shell. Limiting shells are fixedly disposed on both outer walls of the fixed shell. A stop block is slidably disposed inside the limiting shell. The U-shaped rod is disposed on both sides of the fixed shell, and one end of the U-shaped rod extends into the interior of the limiting shell and is fixedly connected to the stop block. Insertion holes are opened on both outer walls of the sealing ring, and the end of the U-shaped rod away from the stop block is inserted into the insertion hole.
[0009] Preferably, a spring is fixedly installed on the side of the stop block near the U-shaped rod, and the other end of the spring is fixedly connected to the inner wall of the fixed shell.
[0010] Preferably, a pull block is fixedly provided at the upper end of the pull rod.
[0011] Preferably, a sealing ring is fitted on the inner wall of the cover, the outer wall of the sealing ring abuts against the inner wall of the cover, and the lower side of the sealing ring abuts against the upper side of the can.
[0012] Preferably, the inner wall of the sealing ring is provided with a rubber gasket.
[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0014] This invention utilizes a lever to move a piston upwards, drawing gas from the tank through a first gas check valve into a fixed shell. Then, by pushing the lever, the piston moves downwards, discharging gas from the fixed shell through a second gas check valve. Repeating this process creates a vacuum in the tank, significantly improving its moisture-proof performance.
[0015] This invention allows for the release of the limiting effect on the fixed shell by pulling the U-shaped rod, which separates one end of the U-shaped rod from the sealing ring, thus facilitating the disassembly of the fixed shell and the maintenance of the vacuum pumping components.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0023] This utility model discloses a ceramic jar with moisture-proof function.
[0024] Reference Figure 1-3 A moisture-proof ceramic jar includes a jar body 1 and a lid 2. The lid 2 is threaded onto the upper part of the jar body 1. A fixed shell 4 is provided on the top of the lid 2. A piston 7 is slidably arranged inside the fixed shell 4. A pull rod 8 is fixedly arranged on the upper side of the piston 7. The upper end of the pull rod 8 extends to the outside of the fixed shell 4. A pull block is fixedly arranged on the upper end of the pull rod 8 to facilitate pulling the pull rod 8. A first through hole is opened at the bottom of the fixed shell 4. A second through hole is opened at the top of the lid 2 at a position corresponding to the first through hole. A first gas one-way valve 6 is fixedly arranged between the first through hole and the second through hole. An exhaust hole is opened on the lower front side of the fixed shell 4. A second gas one-way valve 5 is fixedly arranged inside the exhaust hole. A limiting mechanism is provided on the top of the lid 2 to restrict the movement of the fixed shell 4 relative to the lid 2.
[0025] Reference Figure 1-3 The limiting mechanism includes a U-shaped rod 13 and a sealing ring 3. The sealing ring 3 is fixedly installed on the upper surface of the cover 2. The inner wall of the sealing ring 3 abuts against the outer wall of the fixed shell 4. A rubber gasket is provided on the inner wall of the sealing ring 3 to improve the sealing between the fixed shell 4 and the cover 2. Limiting shells 10 are fixedly installed on both outer walls of the fixed shell 4. A stop block 11 is slidably installed inside the limiting shell 10. The U-shaped rod 13 is installed on both sides of the fixed shell 4. One end of the U-shaped rod 13 extends into the interior of the limiting shell 10 and is fixedly connected to the stop block 11. Insertion holes are opened on both outer walls of the sealing ring 3. The end of the U-shaped rod 13 away from the stop block 11 is inserted into the insertion hole. A spring 12 is fixedly installed on the side of the stop block 11 close to the U-shaped rod 13. The other end of the spring 12 is fixedly connected to the inner wall of the fixed shell 4 to facilitate the reset of the stop block 11.
[0026] Reference Figure 1-3 A sealing ring 9 is fitted on the inner wall of the cover 2. The outer wall of the sealing ring 9 abuts against the inner wall of the cover 2, and the lower side of the sealing ring 9 abuts against the upper side of the tank 1, thereby improving the sealing between the cover 2 and the tank 1.
[0027] In this utility model, when in use, the items to be stored are first placed into the can 1, and then the lid 2 is threaded onto the upper part of the can 1. At this time, the sealing ring 9 is tightly attached to the inner wall of the lid 2 and the upper side of the can 1, which enhances the sealing effect.
[0028] Next, by pulling the lever 8, the piston 7 moves upward inside the fixed shell 4, and the gas inside the tank enters the fixed shell 4 through the first gas one-way valve 6. Due to the one-way characteristic of the first gas one-way valve 6, the gas can only enter the fixed shell 4 from the tank. Then, by pushing the lever 8, the piston 7 moves downward, and the gas inside the fixed shell 4 is discharged through the second gas one-way valve 5. By repeating the action of pulling and pushing the lever 8, the tank can be gradually evacuated, effectively preventing external moisture from entering the tank and maintaining good moisture-proof performance inside the tank.
[0029] When it is necessary to disassemble the fixed shell 4 for maintenance, pull the U-shaped rod 13 to separate one end of the U-shaped rod 13 from the insertion hole of the sealing ring 3. At this time, the spring 12 is compressed, and the stop block 11 slides in the limiting shell 10, thereby releasing the limitation on the fixed shell 4. The fixed shell 4 can be removed from the cover 2 for convenient inspection and maintenance of the vacuum pumping components. After maintenance, place the fixed shell 4 on the cover 2, release the U-shaped rod 13, and the spring 12 pushes the stop block 11 to reset. One end of the U-shaped rod 13 is inserted into the insertion hole of the sealing ring 3 to limit the fixed shell 4 again.
[0030] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
