[0045] Figure 1 A specific embodiment of the sealed can of the present application is shown. Similar to some conventional sealed cans, the sealed can also includes a can body 100 with an opening at the top and a can cover 200 detachably mounted at the opening at the top of the can body. The can cover 200 is generally cylindrical, and has a bottom surface facing the bottom of the can body 100, a top surface facing away from the bottom surface, and a side surface arranged around the bottom surface and the top surface.

[0046] The key improvement of this embodiment is that the sealed can not only has a drying and moisture absorption function, but also has a child lock to prevent children from opening it. Specifically, the can cover 200 includes:

[0047] A desiccant chamber 205a is provided inside the can lid and contains a desiccant 210.

[0048] The moisture absorption hole 208a is provided on the bottom surface of the tank cover and connects the desiccant cavity with the inner cavity of the tank body.

[0049] Two movable baffles 207 are arranged close to the upper openings of the moisture absorption holes.

[0050] The return spring 206 connected to the movable baffle,

[0051] A baffle extension slot is provided on the side of the tank cover for the movable baffle to extend out.

[0052] A flexible sealing ring 209 is arranged around the outer periphery of the side of the can cover and blocks the baffle from extending out of the gap, and

[0053] An actuating member drivingly connected to the movable baffles 207 and used for driving the two movable baffles 207 to move away from each other.

[0054] The movable baffle 207 is provided with a moisture permeable hole 207a corresponding to the moisture absorption hole 208a. The actuator has a first working position and a second working position. When the actuator is in the first working position, the two movable baffles 207 approach each other under the elastic force of the return spring 206, the moisture permeable hole 207a and the moisture absorption hole 208a are arranged in a staggered manner, and the movable baffle 207 blocks the upper end opening of the moisture absorption hole 208a, and the desiccant 210 cannot absorb the moisture in the tank body. When the actuator is in the second working position, the actuator drives the two movable baffles 207 to overcome the elastic force of the return spring 206 and move away from each other, so that the two movable baffles 207 extend out of the baffle extension gap and squeeze the flexible sealing ring 209 to expand outward, the moisture permeable hole 207a and the moisture absorption hole 208a are connected to each other, and the desiccant 210 in the tank cover 200 can absorb the moisture in the tank body 100, providing a dry environment for the product stored in the tank body.

[0055] It is not difficult to see from the above that when the actuator is in the second working position, the two movable baffles 207 move away from each other and squeeze the flexible sealing ring 209, so that the flexible sealing ring 209 expands outward, thereby increasing the radial squeezing force of the flexible sealing ring 209 on the inner wall of the tank body 100, thereby enhancing the connection strength and sealing performance of the tank cover 200 and the tank body 100, and at this time, the moisture permeable hole 207a is connected with the moisture absorption hole 208a, and the desiccant absorbs moisture from the tank body. When the actuator is in the first working position, the two movable baffles 207 move away from each other and no longer squeeze the flexible sealing ring 209, the flexible sealing ring 209 shrinks back, and the radial squeezing force of the flexible sealing ring 209 on the inner wall of the tank body 100 is reduced, which is convenient for the user to remove the tank cover 200, and at this time, the moisture permeable hole 207a and the moisture absorption hole 208a are isolated from each other, the moisture absorption hole 208a is blocked, and the desiccant in the removed tank cover 200 no longer does useless moisture absorption work, thereby increasing the service life of the desiccant.

[0056] In this embodiment, a button hole extending downward is formed on the top surface of the tank cover 200, and the actuating member is a button 202 movably arranged in the button hole.

[0057] The button 202 comprises a button body 202a which is thick at the top and thin at the bottom, and a rotating sleeve 202b which is rotatably connected to the button body. The outer peripheral surface of the rotating sleeve 202b is provided with a male clamping platform 202c which is radially convex outward, and the wall of the button hole is provided with a female clamping platform 203a which is radially convex inward and matches the male clamping platform, and the bottom of the button body 202a is sandwiched between the two movable baffles 207.

[0058] In actual use, the user rotates the rotating sleeve 202b so that the male card platform 202c on it and the female card platform 203a in the button hole are staggered, and the button 202 is pressed downward to move the rotating sleeve 202b and the button body 202a downward. The button body 202a, which is thick at the top and thin at the bottom, moves downward and pushes away the two movable baffles 207, so that the two movable baffles 207 move away from each other and radially squeeze the flexible sealing ring 209 outward, and the flexible sealing ring 209 expands outward and contacts the inner wall of the tank. Then, the rotating sleeve 202b is rotated again so that the male card platform 202c on it is just rotated to the bottom of the female card platform 203a in the button hole. Under the limiting effect of the female card platform 203a, the rotating sleeve 202b cannot move upward, and the button 202 is fixed in the pressed position. If the user needs to remove the can cover 200, the rotating sleeve 202b is rotated to make the male latch 202c on it staggered with the female latch 203a in the button hole. Under the elastic force of the return spring 206, the two movable baffles 207 approach each other and squeeze the button body 202a, which is thick at the top and thin at the bottom, to move upward, and the rotating sleeve 202b moves upward synchronously with the button body 202a.

[0059] In order to improve the smoothness of the button body 202a pushing the two movable baffles 207 outwards and the two movable baffles 207 pushing the button body 202a upwards, in this embodiment, the contact surface between the button body 202a and the movable baffles 207 is set as an inclined surface.

[0060] Furthermore, the can cover 200 further includes a cover seat 201, a pressing cover 202, a desiccant storage bin 205 and a moisture absorbing plate 208. Among them:

[0061] A first vertical through hole is provided in the cover seat 201, and the above-mentioned mother card platform 203a is specifically arranged at the hole wall of the first vertical through hole. The pressing cover 202 is fixed to the upper part of the cover seat, and a second vertical through hole is provided in the pressing cover. The desiccant storage bin 205 is fixedly connected to the cover seat 201, and a third vertical through hole and the above-mentioned desiccant cavity 205a located at the periphery of the third vertical through hole and open at the bottom are provided in the desiccant storage bin 205, that is, the above-mentioned desiccant cavity 205a is specifically arranged in the desiccant storage bin 205. The above-mentioned first vertical through hole, the second vertical through hole and the third vertical through hole together form the above-mentioned button hole. The desiccant plate 208 is fixed to the bottom of the desiccant storage bin 205, and the above-mentioned desiccant hole 208a is set through the desiccant plate, and the baffle extending seam is formed between the desiccant plate 208 and the desiccant storage bin 205.

[0062] In this embodiment, the return spring 206 is a compression spring sandwiched between the desiccant storage bin 205 and the movable baffle 207. Specifically, the movable baffle 207 is integrally provided with a convex ridge 207b protruding upward and extending into the third through hole, and the wall of the third through hole is integrally provided with a spring positioning column 205b extending radially inward, one end of the return spring 206 is sleeved outside the spring positioning column 205b and abuts against the wall of the third through hole, and the other end abuts against the convex ridge 207b.

[0063] The radial dimension of the pressing outer cover 202 is relatively large, and it is supported above the opening edge of the top of the can body 100 to prevent the can cover 100 from sinking into the interior of the can body 100 as a whole.

[0064] The bottom of the button body 202 a is specifically sandwiched between the ridges 207 b of the two movable blocking pieces 207 .

[0065] In order to monitor the temperature and humidity in the tank in real time, in this embodiment, a downwardly recessed groove 202d is formed on the top of the button 202, and a temperature and humidity display meter 201 is embedded in the groove.

[0066] The flexible sealing ring 209 is a circular structure. In order to allow the movable baffle 207 to squeeze various parts of the flexible sealing ring more evenly, the movable baffle 207 has an arc-shaped outer edge.

[0067] To prevent the cover 201 and the pressing cover 202 from rotating when the user rotates the rotating sleeve 202b on the button, the present embodiment provides anti-slip ridges on the outer peripheral surface of the pressing cover 202. The user can hold the pressing cover 202 with one hand and rotate the rotating sleeve 202b with the other hand.

[0068] Of course, the above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable people to understand the content of the present application and implement it accordingly, and they cannot be used to limit the protection scope of the present application. Any equivalent transformation or modification made according to the spirit of the main technical solution of the present application should be included in the protection scope of the present application.
