A plant fungicide storage tank structure with a sealing and leak-proof mechanism

Abstract

This utility model provides a plant fungicide storage tank structure with a sealing and leak-proof mechanism, relating to the field of storage tank technology. It includes a tank body with a tank opening on its top surface, an outer cover on the top of the tank body, an inner cover inside the outer cover, and a sealing element inside the inner cover. The top surface of the sealing element has a movable chamber, and the bottom surface of the sealing element has a liquid inlet. The movable chamber has four limiting posts inside, with a return spring in the middle of the four limiting posts. When the fungicide is no longer needed, releasing the button causes the sealing plug in the movable chamber to automatically return to its original position under the action of the bottom return spring, re-blocking the flow channel connected to the movable chamber. This effectively prevents accidental leakage even when the container is tilted. It solves the problem that if the container is bumped during use, the internal liquid is easily impacted and surges, causing the cap to loosen or fall off, resulting in overflow from the bottle opening, which is wasteful and may pollute soil and water sources, damaging the ecological environment.

Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, and in particular to a structure for a plant fungicide storage tank with a sealing and leak-proof mechanism. Background Technology

[0002] According to Chinese Publication No. CN218318498U, a sealed storage device for a disinfectant includes a storage tank. The top of the storage tank is detachably fitted with a cap. A push plate is movably connected to the inner cavity of the storage tank. Through holes are formed on both sides of the surface of the push plate. A limiting rod is fixedly connected between the upper and lower ends of the inner cavity of the storage tank, and the limiting rod is inserted into the through holes. This invention utilizes a push plate and a spring. When the disinfectant is loaded into the storage tank, the weight of the disinfectant compresses the spring. During the disinfection process, as the amount of disinfectant decreases, its mass decreases, and the spring's elasticity decreases. This causes the spring to push the push plate upwards, keeping the disinfectant at the opening of the storage tank for easy access. Simultaneously, a rubber sealing ring cleans the inner wall of the storage tank, preventing disinfectant adhering deep within the storage tank from becoming difficult to remove.

[0003] In daily use, users inevitably bump into the storage tanks of the aforementioned and existing technologies due to carelessness. However, existing bottled plant fungicide storage tanks generally lack effective sealing and leak-proof mechanisms. Once the tank is impacted, the plant fungicide, which was originally in a relatively static state inside, will surge violently due to the shaking and impact. At this time, without the cap to seal it, the plant fungicide will flow out of the bottle opening. This results in waste of the fungicide and pollution of the surrounding soil, water sources, and other environmental factors, disrupting the ecological balance. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing bottled plant fungicide storage tanks, which lack an effective sealing and leak-proof structure. If the tank is bumped during use, the internal liquid is prone to surge due to the impact, and the cap may loosen or fall off, causing leakage from the bottle opening. This not only results in waste but may also pollute the soil and water sources, damaging the ecological environment. Therefore, this invention proposes a plant fungicide storage tank structure with a sealing and leak-proof mechanism.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a plant fungicide storage tank structure with a sealing and leak-proof mechanism, comprising a tank body, a tank opening on the top surface of the tank body, an outer cover on the top of the tank body, an inner cover inside the outer cover, a sealing element inside the inner cover, a movable chamber on the top surface of the sealing element, a liquid inlet on the bottom surface of the sealing element, four limiting posts inside the movable chamber, a return spring in the middle of the four limiting posts, a sealing plug on the top of the return spring, a flow channel inside the inner cover, a telescopic tube inside one end of the flow channel, four through holes around the flow channel, a sealing sleeve at the top of each of the four through holes, two sealing rings inside each sealing sleeve, four connecting posts on the top surface of the sealing plug, and a pressing plate on the top of the inner cover.

[0006] Preferably, the inner cover is threaded to the tank body, the outer cover is threaded to the inner cover, one end of the seal is installed inside the tank opening, and the seal is installed inside the tank opening through the inner cover.

[0007] Preferably, the cross-section of the flow channel is L-shaped, and the telescopic tube is threaded to one end of the flow channel.

[0008] Preferably, the liquid inlet on the bottom surface of the seal is connected to the movable chamber on the top surface, and the movable chamber is connected to the flow channel. The liquid inlet is perpendicular to the end of the movable chamber and the flow channel away from the installation telescopic tube. The limiting posts inside the movable chamber are arranged in a circumferential array, and the limiting posts are integrally formed with the seal.

[0009] Preferably, the sealing plug is installed inside the movable compartment and is located in the middle of the four limiting posts, with the bottom surface of the sealing plug abutting the top of the return spring.

[0010] Preferably, the sealing plug is integrally formed with the four connecting posts on the top surface, and the positions of the connecting posts correspond one-to-one with the positions of the through holes on the inner cover surface. All four connecting posts pass through the through holes and extend out of the inner cover, and the push plate is inserted into the top of the connecting posts.

[0011] Preferably, the cross-section of the four through holes is T-shaped, and the sealing sleeves inside the through holes are all bonded to the inner cover. The two sealing rings inside the sealing sleeves are snapped into the sealing sleeves, and the connecting posts penetrate the sealing sleeves and the sealing rings inside the sealing sleeves.

[0012] Beneficial effects

[0013] In this invention, an inner cover is installed at the can opening for the first layer of sealing, firmly fixing the sealing element inside the can opening to form a stable seal. An outer cover is then installed outside the inner cover to achieve a second layer of sealing, ensuring the safety of the can during transportation and storage. In use, first unscrew the outer cover, then rotate the telescopic tube located inside the inner cover's flow channel to extend it. Next, tilt the can and press the push plate on top of the inner cover. Under external force, the push plate moves downwards, causing the sealing plug to move downwards synchronously through the connecting column, disengaging the sealing plug from the closed position of the inner cover's flow channel and forming a liquid passage. At this point, the plant fungicide inside the can enters the movable chamber of the sealing element through the inlet at the bottom of the sealing element, and then flows through the opened flow channel into the telescopic tube, finally flowing out from the end of the telescopic tube, achieving directional pouring. When dispensing the fungicide is no longer needed, releasing the button causes the sealing plug inside the movable compartment to automatically return to its original position under the action of the bottom return spring, re-blocking the flow channel connecting to the movable compartment. This effectively prevents the fungicide from flowing out even when tilted, thus preventing accidental leakage. This solution addresses the shortcomings of existing bottled plant fungicide storage containers, which lack an effective sealing and leak-proof structure. These containers are prone to overflowing due to impacts during use, causing the cap to loosen or fall off, resulting in waste and potential soil and water pollution, thus damaging the ecological environment.

[0023] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-7A plant fungicide storage tank structure with a sealing and leak-proof mechanism includes a tank body 1, a tank opening 3 on the top surface of the tank body 1, an outer cover 2 on the top of the tank body 1, an inner cover 5 inside the outer cover 2, a sealing element 4 inside the inner cover 5, a movable chamber 11 on the top surface of the sealing element 4, a liquid inlet 17 on the bottom surface of the sealing element 4, four limiting posts 13 inside the movable chamber 11, a return spring 12 in the middle of the four limiting posts 13, a sealing plug 14 on the top of the return spring 12, and a flow channel inside the inner cover 5. Channel 6 has a telescopic tube 7 inside one end. Four through holes 8 are located around the channel 6, and each of the four through holes 8 has a sealing sleeve 9 at its top. Each sealing sleeve 9 has two sealing rings 10 inside. The top surface of the sealing plug 14 has four connecting posts 15. The top of the inner cover 5 has a pressing plate 16. The inner cover 5 is threaded to the tank body 1, and the outer cover 2 is threaded to the inner cover 5. One end of the sealing element 4 is installed inside the tank opening 3, and the sealing element 4 is installed inside the tank opening 3 through the inner cover 5. The cross-section of the channel 6 is L-shaped. The telescopic tube 7 and... One end of the flow channel 6 is threaded. The liquid inlet 17 on the bottom surface of the seal 4 is connected to the movable chamber 11 on the top surface, and the movable chamber 11 is connected to the flow channel 6. The liquid inlet 17 is perpendicular to the end of the movable chamber 11 and the flow channel 6 away from the installation of the telescopic tube 7. The limiting posts 13 inside the movable chamber 11 are arranged in a circumferential array, and the limiting posts 13 are integrally formed with the seal 4. The sealing plug 14 is installed inside the movable chamber 11, and the sealing plug 14 is located in the middle of the four limiting posts 13. The bottom surface of the sealing plug 14 is in contact with the top of the return spring 12. The sealing plug 14 is integrally formed with the four connecting posts 15 on the top surface, and the positions of the connecting posts 15 correspond one-to-one with the positions of the through holes 8 on the surface of the inner cover 5. All four connecting posts 15 pass through the through holes 8 and extend out of the inner cover 5. The pressing plate 16 is inserted into the top of the connecting posts 15. The cross-section of the four through holes 8 is T-shaped, and the sealing sleeves 9 inside the through holes 8 are all bonded to the inner cover 5. The two sealing rings 10 inside the sealing sleeves 9 are all snapped into the sealing sleeves 9, and the connecting posts 15 all pass through the sealing sleeves 9 and the sealing rings 10 inside the sealing sleeves 9.

[0027] When the plant fungicide storage tank with a sealing and leak-proof mechanism is in operation, the outer cover 2 and the inner cover 5 form a double seal. The outer cover 2 is fixed to the outside of the inner cover 5 by a threaded structure that is opposite to that of the inner cover 5, preventing the inner cover 5 from being loosened when the outer cover 2 is unscrewed, and ensuring a stable and reliable connection between the inner cover 5 and the tank opening 3. The inner cover 5 is installed on the tank opening 3 of the tank body 1 by threads and fixes the internal sealing element 4. The liquid inlet 17 at the bottom of the sealing element 4 is connected to the movable chamber 11 at the top. The middle of the movable chamber 11 is supported by a return spring 1. 2. Supporting the sealing plug 14, when the return spring 12 is in the compressed state, the sealing plug 14 will disengage from the flow channel 6. When in the released state, the sealing plug 14 will tightly fit the flow channel 6 under the action of elasticity to achieve sealing. The limiting posts 13 evenly distributed around the movable chamber 11 play a role in centering the sealing plug 14 and limiting the position of the return spring 12, so that it maintains coaxiality with the flow channel 6 during up and down movement, avoiding sealing failure due to displacement. The sealing plug 14 and the four connecting posts 15 are an integral structure. 15 extends through the through hole 8 on the inner cover 5. A sealing sleeve 9 is installed inside the through hole 8. The double sealing ring 10 fitted inside the sealing sleeve 9 is in close contact with the outer wall of the connecting column 15, preventing liquid leakage due to gaps when the connecting column 15 slides up and down. Simultaneously, the T-shaped structure of the through hole 8's cross-section provides a stable and secure position for the sealing sleeve 9, preventing it from loosening or shifting. The push plate 16 is inserted into the top of the connecting column 15. Pressing the push plate 16 with external force allows the connecting column 15 to move downwards as a whole. The sealing plug 14 is moved downwards and disengaged from the flow channel 6, allowing the movable chamber 11 to connect with the flow channel 6. The flow channel 6 has an L-shaped cross-section, with one end connected to the movable chamber 11 and the other end threadedly connected to the telescopic tube 7. The telescopic tube 7 can be screwed in or out along the thread of the flow channel 6 to adjust the pouring length. It also ensures that after the liquid enters the movable chamber 11 through the inlet 17, it flows into the telescopic tube 7 through the opened flow channel 6 and is then discharged. The sealing element 4 is used to guide the fungicide and to fix the reset spring 12 and the sealing plug 14. When the press plate 16 is released after use, the reset spring 12 returns to its original state, pushing the sealing plug 14 back to its original position and blocking the flow channel 6, so that the tank 1 will not leak even when tilted. This achieves sealed protection and controllable output of the plant fungicide from storage to pouring, effectively solving the problem of leakage and waste caused by the cap coming loose when the tank 1 is hit or shaken, while also avoiding pollution to the surrounding environment. Specific Implementation Example 2:

[0029] Reference Figure 1-7A plant fungicide storage tank structure with a sealing and leak-proof mechanism is further based on the basic structure in Specific Embodiment 1, and a sealing gasket can be embedded in the top surface of the sealing plug 14. In the transportation or storage state, the can opening 3 of the tank body 1 is sealed by the inner cover 5. The inner cover 5 is firmly fixed inside the can opening 3 by a threaded connection, and the sealing element 4 is stably locked. The inlet of the flow channel 6 communicating with the movable chamber 11 of the sealing element 4 is sealed by the sealing plug 14 and the sealing gasket embedded in the top surface of the sealing plug 14. When the sealing plug 14 contacts the flow channel 6, the sealing gasket generates a circumferential uniform sealing pressure, forming a more reliable sealing effect. The outer cover 2 is sealed by a thread that is reversed from the inner cover 5 to prevent the inner cover 5 from loosening due to external vibration or impact during transportation. When needed, first unscrew the outer cover 2. Since the threads of the outer cover 2 and the inner cover 5 are opposite, it can effectively prevent the inner cover 5 from being screwed out when the outer cover 2 is rotated, ensuring the stability of the sealing state. Then rotate the telescopic tube 7 at the end of the flow channel 6 of the inner cover 5, so that it extends along the threaded guide to the appropriate liquid pouring length. The telescopic tube 7 and the flow channel 6 are threadedly connected and form an L-shaped channel, making the flow path structurally stable and reliable. During the liquid pouring process, the tank 1 is tilted and the push plate 16 located on the top of the inner cover 5 is pressed. When the push plate 16 moves down, it drives the connecting post 15 inserted with it to move downward. The connecting post 15 passes through the through hole 8, sealing sleeve 9 and sealing ring 10 of the inner cover 5 and is an integral structure with the sealing plug 14. Therefore, it will drive the sealing plug 14 and the sealing gasket on its top surface to move down synchronously. After the sealing plug 14 is separated from the inlet of the flow channel 6, the interior of the movable chamber 11 is connected to the flow channel 6. The plant fungicide inside the tank 1 enters the movable chamber 11 through the liquid inlet 17 at the bottom of the seal 4 under the action of gravity, and then flows out along the flow channel 6 and the telescopic tube 7, flowing in a direction to the target position. When the push plate 16 is released, the reset spring 12 pushes the sealing plug 14 back to its original position. The sealing gasket and the sealing plug 14 press against the inlet of the flow channel 6 again, blocking the liquid flow path. Even if the tank 1 is still in the tilted state, there will be no leakage, ensuring operational safety and environmental protection.

[0030] In summary:

[0031] 1. An inner cover 5 is installed at the opening 3 of the tank body 1 for the first seal. The inner cover 5 firmly fixes the sealing element 4 inside the opening 3, forming a stable seal. An outer cover 2 is then installed outside the inner cover 5 to achieve a second seal, ensuring the safety of the tank body 1 during transportation and storage. In use, first unscrew the outer cover 2, then rotate the telescopic tube 7 located inside the flow channel 6 of the inner cover 5 to extend it. Then, tilt the tank body 1 and press the push plate 16 on top of the inner cover 5. The push plate 16 moves downward under external force, driving the sealing plug 14 downward synchronously through the connecting column 15, causing the sealing plug 14 to disengage from the closed position of the flow channel 6 of the inner cover 5, forming a liquid passage. At this time, the plant fungicide inside the tank body 1 enters the movable chamber 11 of the sealing element 4 through the liquid inlet 17 at the bottom of the sealing element 4, and enters the telescopic tube 7 through the opened flow channel 6, finally flowing out from the end of the telescopic tube 7, achieving directional pouring. When dispensing the fungicide is no longer needed, release the button 16. The sealing plug 14 inside the movable chamber 11 automatically returns to its original position under the action of the bottom return spring 12, re-blocking the flow channel 6 connected to the movable chamber 11. This prevents the fungicide from flowing out even when tilted, effectively preventing accidental leakage. This solves the problem of existing bottled plant fungicide storage tanks lacking an effective sealing and leak-proof structure. If the tank is bumped during use, the internal liquid can easily surge due to the impact, causing the cap to loosen or fall off and overflow from the bottle opening. This results in waste and potential pollution of soil and water sources, damaging the ecological environment.
