DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1 See also Figure 1-9 The present invention provides the following technical solutions: a double-layer sealed tea tin can packaging box, comprising a can body 1 and a can cover 2, an adjusting plate 3 is arranged inside the can body 1, a screw rod 4 is installed on the inner wall of the can body 1, a bearing 5 is installed on one end of the screw rod 4, a motor 6 is connected to the other end of the screw rod 4, a threaded sleeve 7 is threadedly connected to the surface of the screw rod 4, a top rod 8 is connected to the top surface of the thread sleeve 7, an inner film bag 10 is connected to the inside of the can body 1, a battery 9 is connected to the inner bottom end surface of the can body 1, a sealing gasket 11 is installed inside the can cover 2, a non-woven fabric 12 is bonded to the sealing surface of the sealing gasket 11, and a start button 26 is connected to the front end surface of the can body 1.

[0019] In the preferred embodiment: the top end of the inner film bag 10 is bonded to the top end of the inner wall of the tank body 1 , the bottom end of the inner film bag 10 is bonded to the top surface of the adjustment plate 3 , and the inner film bag 10 is made of PE material.

[0020] In the preferred embodiment, two ends of the adjusting plate 3 are connected to the outer side walls of the thread sleeve 7 , and the adjusting plate 3 is connected to the screw rod 4 through the thread sleeve 7 to form a threaded lifting connection.

[0021] In the preferred embodiment, the screw rod 4 is rotationally connected to the tank body 1 through the motor 6 and the bearing 5 , and the motor 6 , the start button 26 and the battery 9 are electrically connected.

[0022] In the preferred embodiment, the non-woven fabric 12 is a medical-grade high-quality non-woven fabric, the sealing pad 11 is made of food-grade rubber material, and the non-woven fabric 12 and the sealing pad 11 are adapted to the size of the interior of the tank body 1 .

[0023] In the embodiment, firstly, the tin can packaging box for tea is composed of a can body 1 and a can cover 2 and is made of iron. Meanwhile, the tin can packaging box for tea is an existing mature product, and thus will not be described in detail in the text.

[0024] In addition, the top of the inner film bag 10 is bonded to the top of the inner wall of the can body 1, so that the tea leaves will be directly placed in the inner film bag 10 for storage, and then the can lid 2 is closed with the can body 1, and the sealing pad 11 and the non-woven fabric 12 will extend into the interior of the can body 1 and be connected to the inner wall of the inner film bag 10, thus forming a double-layer seal. The tea tin can packaging box is a first-layer seal, and the inner film bag 10, the non-woven fabric 12 and the sealing pad 11 form a second-layer seal. This design significantly improves the sealing performance of the tea tin can packaging box, effectively preventing the intrusion of external factors such as moisture and oxygen, and ensuring the long-term freshness and quality of the tea leaves.

[0025] It should be noted that the use of the non-woven fabric 12 is to ensure the taste of the tea and isolate the influence of the smell of the sealing pad 11 on the tea. The porous structure of the non-woven fabric 12 makes it have good air permeability, allowing air circulation while effectively isolating the smell. At the same time, the non-woven fabric 12 is non-toxic and harmless, further reducing the influence on the taste of the tea.

[0026] Next, after the tea in the tea tin can packaging box is gradually consumed, the motor 6 is controlled to work through the start button 26, and the battery 9 provides power for the motor 6 to start, and then the output shaft of the motor 6 drives the screw 4 to rotate along the inner ring of the bearing 5 inside the tank body 1, followed by the thread sleeve 7 starting to move along the thread on the surface of the screw 4. At the same time, the thread sleeve 7 will drive the adjustment plate 3 to rise, and the adjustment plate 3 will drive the inner film bag 10 to rise, and then adjust the position of the adjustment plate 3 and the inner film bag 10, so as to facilitate the lifting of the remaining tea to the loading and unloading place close to the tank body 1. This design greatly facilitates the process of taking out the tea, and avoids the situation where the tea accumulates at the bottom of the inner film bag 10 and is difficult to take out due to the depth of the tank body 1.

[0027] It is worth noting that a push rod 8 is connected to the top of the wire sleeve 7. The purpose of this design is to prevent the inner film bag 10 from bending and extending into the assembly groove of the screw rod 4 when it is lifted up, and then twisting into the connection between the screw rod 4 and the wire sleeve 7. As the wire sleeve 7 rises, the push rod 8 will play a role and push out the inner film bag 10 that has extended into the assembly groove.

[0028] Embodiment 2 See also Figure 1-9 A placement box 13 is provided at the bottom end of the tank body 1, and two symmetrical fixing blocks 14 are installed at the bottom end of the tank body 1. A threaded rod 15 is threadedly connected to the surface of the fixing block 14, and a clamping block 16 is installed at the end of the threaded rod 15. A rotating groove 17 is provided on the side wall of the clamping block 16, and through holes 18 are provided on both sides of the bottom end of the tank body 1.

[0029] In the preferred embodiment, the rotation groove 17 is in a convex shape, and the rotation groove 17 is adaptively connected to one end of the threaded rod 15 .

[0030] In the preferred embodiment, the clamping block 16 forms a threaded reciprocating motion with the fixing block 14 through the threaded rod 15 , and the top end surface of the clamping block 16 is attached to the bottom end of the tank body 1 .

[0031] In the embodiment, a placement box 13 is provided at the bottom end of the tank body 1 for storing anthelmintics. By rotating the threaded rod 15, it rotates smoothly along the rotation groove 17, and simultaneously moves along the threaded groove passing through the fixing block 14. This movement causes the threaded rod 15 to push the clamping block 16 to move, and then the placement box 13 fits tightly to the bottom end of the tank body 1. As the threaded rod 15 continues to rotate and advance, the clamping block 16 fixes the placement box 13. Subsequently, the smell of the anthelmintic is released from the opening on the placement box 13, and then diffuses through the through hole 18. This innovative design effectively reduces the risk of the tea tin can packaging box attracting insects to gnaw the sealing layer due to the storage environment such as dry, cool, and light-proof conditions, and ensures the hygienic safety of the tea and the integrity of the packaging.

[0032] It is worth noting that the top surface of the clamping block 16 is in contact with the bottom end of the tank body 1. This design prevents the clamping block 16 from rotating along with the threaded rod 15. The tank body 1 limits the position of the clamping block 16 so that it can only move forward or backward along with the rotation of the threaded rod 15.

[0033] Embodiment 3 See also Figure 1-9 The front end face of the tank body 1 is connected to a fixing box 19, a card 20 is inserted inside the fixing box 19, a fixing plate 21 is inserted at one end of the fixing box 19 close to the plug interface, a supporting block 22 is connected to the top of the fixing box 19, a spring 23 is assembled inside the supporting block 22, a supporting rod 24 is connected to the end of the spring 23, and a limiting plate 25 is connected to the end of the supporting rod 24.

[0034] In the preferred embodiment, the limiting plate 25 is elastically linked with the spring 23 through the support rod 24 , and the limiting plate 25 is attached to the top surface of the fixing plate 21 .

[0035] In the embodiment, by pushing the limit plate 25 in the direction of the support block 22, the support rod 24 can be driven to squeeze the spring 23 to shrink, and at the same time the limit plate 25 is moved away from the top of the fixed plate 21, and then the fixed plate 21 is pulled out to release the fixation of the card 20, and then the card 20 is pushed out from the opening of the side wall of the fixed box 19, and then the name of the tea or other relevant information is written on the card 20, and then reconnected to the fixed box 19. This design not only facilitates users to quickly and accurately identify the required tea in multiple tea tin packaging boxes, but also improves the overall convenience of use and user experience.

[0036] It is worth noting that the front end of the fixing box 19 has an opening for convenient observation of the information written on the card 20 .

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
