[0002] The present invention relates to the technical field of herbal medicine storage containers, in particular to a herbal medicine storage container with a moisture-proof structure. Background Art

[0003] Herbal medicine is a medicine made from plant extracts and is the oldest form of health care. Currently, herbal medicine is generally stored in storage containers for future use. After the herbs are placed inside the storage container, the sealing cap is screwed on the top of the storage container for protection to prevent dust, impurities, etc. from entering the interior of the storage container.

[0004] However, the existing herbal medicine storage containers do not have a moisture-proof structure. After the herbs are placed in the storage container and sealed by tightening the sealing cap, a large amount of gas is also sealed inside the storage container, which can easily cause the herbs inside the storage container to become damp and moldy, affecting the subsequent use of the herbs and resulting in poor stability. Summary of the Invention

It is easy to use and has high flexibility, stability and practicality.

[0006] In order to achieve the above-mentioned object, the present invention provides a herbal medicine storage container with a moisture-proof structure, comprising: a container assembly, wherein the container assembly comprises a storage container, a locking cap, an operating cap and an adaptive synchronization block, wherein the locking cap is screwed onto the top of the storage container by a thread, the operating cap is rotatably connected to the interior of the locking cap, and a plurality of adaptive synchronization blocks are radially inserted into the inner circumference of the locking cap and clamped with the outer circumference of the operating cap, and a vacuum pressure gauge is installed on the storage container; a moisture-proof assembly, wherein the moisture-proof assembly comprises a positioning column and an air extraction piston, and an air extraction channel is provided inside the positioning column; the positioning column is provided with an air extraction channel ... locking cap is screwed onto the top of the storage container, the locking cap is screwed onto the top of the storage container, the operating cap is rotatably connected to the interior of the locking cap, and the plurality of adaptive synchronization blocks are radially inserted into the inner circumference of the locking cap and clamped with the outer circumference of the operating cap, and the storage container is provided with a vacuum pressure gauge; the moisture-proof assembly The positioning column is axially inserted into the inner surface of the locking cap, and the top of the positioning column is rotatably connected to the inside of the operating cap. The air pumping piston is located in the corresponding air pumping channel. A return spring is provided on the top of the air pumping piston, and the two ends of the return spring respectively abut the top of the air pumping piston and the inside of the positioning column; a reciprocating groove is provided on the inner circumference of the operating cap, and the reciprocating groove includes a vertical exhaust drive groove and a spiral air pumping drive groove. The top of the air pumping drive groove is connected to the top of the exhaust drive groove, and the reciprocating grooves are connected to each other end to end; a driving protrusion is connected to the movable end of the air pumping piston, and the driving protrusion is inserted in the reciprocating groove.

[0007] Furthermore, a sealing rubber ring is inserted into the bottom of the positioning column, and the sealing rubber ring contacts the top of the storage container.

[0008] Furthermore, the cross-sectional shape of the bottom column of the positioning column is a regular polygon, and a positioning groove is provided on the top of the storage container, and the regular polygonal column portion of the positioning column is inserted into the interior of the positioning groove.

[0009] Furthermore, a one-way channel is provided inside the air extraction piston, a movable air extraction one-way valve is provided inside the one-way channel, and a fixed air extraction one-way valve is provided at the bottom of the air extraction channel.

[0010] Furthermore, a track block with a T-shaped cross-section is provided on the side of the vacuum piston, and an axial track groove is provided at the corresponding position of the inner circumference of the positioning column, and the track block is inserted into the inside of the track groove; the driving protrusion is located at the top of the outer side of the track block.

[0011] Furthermore, a one-way gear ring is provided on the outside of the operating cap, and the cross-sectional shapes of one end of the synchronization block and a single gear tooth of the one-way gear ring are both right-angled triangles, and when the locking cap is rotated in the tightening direction, the straight edges of the gear teeth of the synchronization block and the one-way gear ring are engaged with each other.

[0012] Furthermore, an avoidance top spring is provided inside the adaptive synchronization block, and two ends of the avoidance top spring respectively abut against the inside of the adaptive synchronization block and the inside of the locking cap.

[0013] Another protection purpose of the present application is to use a herbal medicine storage container with an insect-proof function in herbal medicine storage. After the herbs are placed inside the storage container and the locking cap is tightened, the interaction of air inside and outside the storage container can be isolated. By rotating the locking cap, the locking cap can be locked to the top of the storage container through the thread. In the process of locking the locking cap inside the storage container, the positioning column can move with the locking cap and squeeze the sealing rubber ring to achieve the sealing function of the top opening of the storage container, which can play an insect-proof function.

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

[0015] 1. When in use, the container assembly of the present invention can enclose the herbs inside while isolating the outside air from entering, thereby enabling the storage and use of the herbs. The moisture-proof assembly can extract the residual air inside the storage container when the locking cap is locked, so that the residual air inside the storage container is discharged, ensuring that the herbs can be stably stored inside the container assembly without moisture or mold. It can effectively prevent dust, mold, moisture, and insects, and is stable in use. Even after the locking cap is locked, the operating cap can still be rotated to continue to extract the residual air inside the storage container, thereby improving the flexibility, adaptability, and practicality of the device.

[0016] 2. The container assembly of the present invention has a self-sealing structure. When the locking cap is locked onto the top of the storage container, it isolates the air from the inside and outside of the container. By rotating the locking cap, the threaded locking cap is locked to the top of the storage container. As the locking cap is locked into the container, the positioning post moves with the locking cap and compresses the sealing rubber ring, thereby sealing the top opening of the storage container. This provides dust and insect protection, and is stable, easy to install and remove, and highly flexible.

[0017] 3. When the locking cap is locked on the top of the storage container, the moisture-proof assembly of the present invention can extract and discharge the air trapped inside the storage container, thereby preventing the stored herbs from getting damp and moldy. When the locking cap is rotated and locked (the direction of the locking cap rotation is considered the positive direction), the positioning post is unable to rotate with the locking cap under the action of the positioning groove. At this time, the straight edges of the gear teeth of the adaptive synchronization block and the one-way gear ring are always engaged with each other under the action of the avoidance spring. Therefore, when the locking cap is rotated and locked, it can always drive the operating cap to rotate synchronously through the adaptive synchronization block. When the operating cap rotates, it can drive the air extraction piston to reciprocate up and down under the action of the reciprocating groove and the return spring, thereby realizing the function of extracting and discharging the residual air inside the storage container. In other words, the device realizes the moisture-proof and mold-proof functions, is convenient to use, and is flexible to operate.

[0018] 4. The present invention employs a fixed one-way valve in the air extraction channel and a movable one-way valve within the one-way valve. With the cooperation of the two, when the air extraction piston moves upward, the air inside the storage container can be drawn into the interior of the positioning column through the air extraction channel. When the air extraction piston moves downward, the air drawn from the interior of the positioning column can be discharged through the one-way valve, thereby achieving automated operation of extracting air from the storage container.

[0019] 5. In this invention, when the operating cap rotates forward (either alone or in conjunction with the locking cap), the suction drive groove, via the driving protrusion, drives the suction piston upward, compressing the return spring. When the driving protrusion enters the exhaust drive groove from the suction drive groove, the vertical design of the exhaust drive groove allows the suction piston to quickly descend and enter the adjacent reciprocating groove's exhaust drive groove, thereby achieving reciprocating upward and downward motion when the operating cap rotates forward, ensuring smooth operation and stable use.

[0020] 6. After the locking cap is locked to the top of the storage container, the present invention still allows the operation of pumping out the residual air inside the storage container by rotating the operating cap forward alone. When the operating cap is rotated forward alone, the beveled edge of the teeth of the one-way gear ring of the operating cap and the beveled edge of the block of the adaptive synchronization block squeeze each other. As a result, the adaptive synchronization block automatically moves inward of the locking cap under the squeezing action of the beveled edge of the teeth of the one-way gear ring to avoid and compress the avoidance spring. The operating cap can then be rotated forward alone to continue pumping out the residual air inside the storage container. This is convenient to use, and the locking structure composed of the locking cap, operating cap, adaptive synchronization block and moisture-proof assembly can be used with storage containers of different volumes, with strong adaptability.

[0021] 7. When the locking cap needs to be removed to access the herbs inside the storage container, the locking cap can be simply reversed. When the locking cap is rotated in the reverse direction, the synchronization block can still automatically move toward the interior of the locking cap under the squeezing action of the beveled edge of the gear teeth of the one-way gear ring to avoid and compress the avoidance spring. As a result, the locking cap can be freely reversed and removed from the top of the storage container. During this process, the moisture-proof component will not trigger the air extraction function, making installation and removal convenient and highly flexible. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation Method

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. Example 1

[0038] Please refer to Figures 1 to 11 As shown, the herbal medicine storage container with a moisture-proof structure provided by the present invention includes a container assembly 1 and a moisture-proof assembly 2. The container assembly 1 includes a storage container 101, a locking cap 102, an operating cap 103 and an adaptive synchronization block 104. The locking cap 102 is screwed onto the top of the storage container 101 through a thread, and the operating cap 103 is rotatably connected to the inside of the locking cap 102. A plurality of adaptive synchronization blocks 104 are radially inserted into the inner circumference of the locking cap 102 and clamped with the outer circumference of the operating cap 103. The moisture-proof component 2 includes a positioning column 201 and an air extraction piston 202. The positioning column 201 is provided with several axial air extraction channels 2012; the positioning column 201 is axially inserted into the inner surface of the locking cap 102, and the top of the positioning column 201 is rotatably connected to the inside of the operating cap 103. The air extraction piston 202 is located in the corresponding air extraction channel 2012, and the driving protrusion 2024 is connected to the movable end of the air extraction piston 202. A reciprocating groove is provided on the inner circumference of the operating cap 103, and the driving protrusion 2024 is inserted into the reciprocating groove.

[0039] Among them, a sealing rubber ring 2011 is inserted into the bottom of the positioning column 201, and the sealing rubber ring 2011 contacts the top of the storage container 101. During use, the container assembly 1 has a self-sealing structure, that is, when the locking cap 102 is locked on the top of the storage container 101, it can isolate the interaction of air inside and outside the storage container 101. By rotating the locking cap 102, the locking cap 102 can be locked to the top of the storage container 101 through the thread. In the process of locking the locking cap 102 on the upper part of the storage container 101, the positioning column 201 can follow the locking cap 102 to move and squeeze the sealing rubber ring 2011, thereby realizing the sealing function of the top opening of the storage container 101, which can play the role of dust and insect prevention, and is stable to use, easy to install and disassemble, and highly flexible.

[0040] The cross-sectional shape of the bottom column of the positioning column 201 is a regular polygon, and a positioning groove 1011 is provided on the top of the storage container 101. The regular polygon column part of the positioning column 201 is inserted into the interior of the positioning groove 101. In use, when the locking cap 102 is locked on the top of the storage container 101, the moisture-proof component 2 can extract the air retained in the storage container 101 and discharge it from the interior of the storage container 101, thereby preventing the herbs stored inside from getting damp and moldy. When the locking cap 102 is rotated and locked (the direction in which the locking cap 102 is rotated and locked is the positive direction), the air in the positioning groove 1011 is drawn out of the storage container 101. Under the action of the positioning column 201, it is always unable to rotate with the locking cap 102, and at this time, under the action of the avoidance top spring 1041, the straight edges of the gear teeth of the adaptive synchronization block 104 and the one-way gear ring 1033 are always engaged with each other, so that the locking cap 102 can always drive the operating cap 103 to rotate synchronously through the adaptive synchronization block 104 when rotating and locking. When the operating cap 103 rotates, it can drive the vacuum piston 202 to reciprocate up and down under the action of the reciprocating groove and the return top spring 2022, thereby realizing the function of extracting and discharging the residual gas inside the storage container 101, that is, realizing the moisture-proof and mildew-proof functions of the device, which is easy to use and flexible to operate.

[0041] The interior of the air extraction piston 202 is provided with a one-way channel 2021, the interior of the one-way channel 2021 is provided with a movable air extraction one-way valve 2013, and the bottom of the air extraction channel 2012 is provided with a fixed air extraction one-way valve 2015. During use, under the coordinated action of the fixed air extraction one-way valve 2015 in the air extraction channel 2012 and the movable air extraction one-way valve 2013 in the one-way channel 2021, when the air extraction piston 202 moves upward, the air inside the storage container 101 can be drawn into the interior of the positioning column 201 through the air extraction channel 2012. When the air extraction piston 202 moves downward, the air drawn from the interior of the positioning column 201 can be discharged through the one-way channel 2021, thereby achieving an automated operation of extracting the air from the storage container 101.

[0042] Among them, the reciprocating groove is composed of a vertical exhaust drive groove 1031 and a spiral exhaust drive groove 1032. The top of the exhaust drive groove 1032 is connected to the top of the exhaust drive groove 1031, and the reciprocating grooves are connected to each other end to end. In use, when the operating cap 103 rotates forward (regardless of whether the operating cap 103 rotates forward alone or rotates forward synchronously with the locking cap 102), the reciprocating groove rotates; since a return spring 2022 is provided on the top of the exhaust piston 202, and the two ends of the return spring 2022 respectively contact the top of the exhaust piston 202 and the inner side of the positioning column 201, The exhaust drive groove 1031 is vertically designed, and the exhaust drive groove 1031 is vertically aligned, so the exhaust piston 202 can move downward quickly under the action of the reset spring 2022 and enter the exhaust drive groove 1031 of the adjacent reciprocating groove, thereby realizing the function of driving the exhaust piston 202 to move up and down when the operating cap 103 rotates forward, and the operation is smooth and the use is stable.

[0043] Among them, the outside of the operating cap 103 is provided with a one-way gear ring 1033, and the cross-sectional shape of a single gear tooth of one end of the adaptive synchronization block 104 and the one-way gear ring 1033 are both right-angled triangles, and when the locking cap 102 is rotated in the tightening direction, the gear straight edges of the adaptive synchronization block 104 and the one-way gear ring 1033 are engaged with each other. In use, when the locking cap 102 is locked on the top of the storage container 101, the storage container can still be pumped out by rotating the operating cap 103 forward alone. The operation of the residual air inside the device 101, when the operating cap 103 is rotated forward alone, the beveled edge of the gear teeth of the one-way gear ring 1033 of the operating cap 103 and the beveled edge of the block of the adaptive synchronization block 104 are squeezed against each other, and the interior of the adaptive synchronization block 104 is provided with an avoidance top spring 1041, and the two ends of the avoidance top spring 1041 respectively contact the interior of the adaptive synchronization block 104 and the interior of the locking cap 102, so that the adaptive synchronization block 104 can be adjusted between the beveled edge of the gear teeth of the one-way gear ring 1033 3, and the cam 103 is pressed against the locking cap 102 to release the locking cap 102. When the locking cap 102 is pressed against the locking cap 102, the cam 103 is pressed against the locking cap 102 to release the locking cap 102. When the locking cap 102 is pressed against the locking cap 102, the cam 103 is pressed against the locking cap 102 to release the locking cap 102. When the locking cap 102 is pressed against the locking cap 102, the cam 103 is pressed against the locking cap 102 to release the locking cap 102.

[0044] Among them, the side of the vacuum piston 202 is provided with a track block 2023 with a T-shaped cross-section, and the interior of the positioning column 201 is provided with a track groove 2014. The track block 2023 is inserted into the interior of the track groove 2014, and the driving protrusion 2024 is located at the top of the outer side of the track block 2023. During use, the track block 2023 can limit the moving trajectory of the vacuum piston 202 through the track groove 2014, so that the vacuum piston 202 will not be skewed or twisted during movement, causing the device to get stuck and fail, and it is stable to use. Example 2

[0045] In another embodiment, a vacuum pressure gauge is installed on the storage container 101, so that a reference can be provided when exhausting the residual air inside the storage container 101, so that the herbs inside the storage container 101 can be stably stored, further improving the flexibility and stability of the device.

[0046] The application of the herbal medicine storage container with insect-proof function of the present invention in herbal medicine storage is to realize the storage function by placing the herbs into the interior of the storage container 101 and locking it with the locking cap 102. The container assembly 1 has a self-sealing structure, that is, when the locking cap 102 is locked on the top of the storage container 101, it can isolate the interaction of air inside and outside the storage container 101. By rotating the locking cap 102, the locking cap 102 can be locked to the top of the storage container 101 through the thread. In the process of locking the locking cap 102 on the upper part of the storage container 101, the positioning column 201 can follow the locking cap 102 to move and squeeze the sealing rubber ring 2011, thereby realizing the sealing function of the top opening of the storage container 101, which can play the role of dust and insect prevention. Furthermore, when the locking cap 102 is locked onto the top of the storage container 101, the moisture-proof assembly 2 can extract and discharge the air trapped inside the storage container 101, thereby preventing the stored herbs from becoming damp and moldy. When the locking cap 102 is rotated and locked (the direction of rotation of the locking cap 102 is considered the forward direction), the positioning post 201 is unable to rotate along with the locking cap 102 due to the action of the positioning slot 1011. Furthermore, the straight edges of the gear teeth of the adaptive synchronization block 104 and the one-way gear ring 1033 are constantly engaged with each other under the action of the avoidance spring 1041. As a result, the locking cap 102 can always drive the operating cap 103 to rotate synchronously via the adaptive synchronization block 104 during rotational locking. When the operating cap 103 is rotated, the reciprocating groove and the return spring 2022 can drive the vacuum piston 202 to reciprocate up and down, thereby realizing the function of extracting and discharging the residual gas inside the storage container 101, that is, realizing the moisture-proof and mildew-proof function of the device. When the operating cap 103 is rotated forward (regardless of whether the operating cap 103 is rotated forward alone or rotated forward synchronously with the locking cap 102), the vacuum driving groove 1032 can drive the vacuum piston 202 to move upward through the driving protrusion 2024 and compress the return spring 2022. When the driving protrusion 2024 enters the exhaust driving groove 1031 from the vacuum driving groove 1032, since the exhaust driving groove 1031 is designed to be vertical, the vacuum piston 202 can quickly move downward under the action of the return spring 2022 and enter the exhaust driving groove 1031 of the adjacent reciprocating groove, thereby realizing the function of driving the vacuum piston 202 to reciprocate up and down when the operating cap 103 is rotated forward.Under the cooperation of the fixed one-way valve 2015 in the air extraction channel 2012 and the movable one-way valve 2013 in the one-way channel 2021, when the air extraction piston 202 moves upward, the air inside the storage container 101 can be sucked into the interior of the positioning column 201 through the air extraction channel 2012. When the air extraction piston 202 moves downward, the air extracted from the interior of the positioning column 201 can be discharged through the one-way channel 2021, thereby realizing the automatic operation of extracting the air from the storage container 101. When the locking cap 102 is locked on the top of the storage container 101, the operation of extracting the residual air inside the storage container 101 can still be achieved by rotating the operating cap 103 forward alone. When the operating cap 103 is rotated forward alone, the beveled edge of the gear teeth of the one-way gear ring 1033 of the operating cap 103 and the beveled edge of the block of the adaptive synchronization block 104 squeeze each other, so that the adaptive synchronization block 104 can automatically move toward the inside of the locking cap 102 under the squeezing action of the beveled edge of the gear teeth of the one-way gear ring 1033 to avoid and compress the avoidance top spring 1041, so that the operating cap 103 can be rotated forward alone to continue to extract the residual air inside the storage container 101, which is easy to use, so that the locking structure composed of the locking cap 102, the operating cap 103, the adaptive synchronization block 104 and the moisture-proof component 2 can be matched with storage containers 101 of different volumes. When the herbs in the storage container 101 need to be taken out for use later, the locking cap 102 can be removed by reversing the locking cap 102. When the locking cap 102 needs to be removed to take out the herbs in the storage container 101 for use, it is only necessary to reverse the locking cap 102. When the locking cap 102 rotates in the opposite direction, the synchronization block 104 can still automatically move toward the inside of the locking cap 102 under the squeezing action of the bevel of the gear teeth of the one-way gear ring 1033 and compress the avoidance spring 1041, so that the locking cap 102 can be freely reversed and removed from the top of the storage container 101, and the moisture-proof component 2 will not trigger the air extraction function during this process.

[0047] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
