By adjusting the sinking depth of the pipe head of the liquid suction pipe, liquid at different depths in the barrel is sucked, and the liquid suction pump sucks quantitative liquid and discharges it through the liquid outlet pipe. The volume of liquid sucked by the liquid suction pump is controllable, thereby achieving the purpose of extracting quantitative liquid from a specified height in a sealed plastic barrel without opening the cover.

[0004] In addition, when the existing sealed barrels are used to store various liquids, the liquids in the barrels may settle, resulting in different concentrations of the liquids taken from different parts of the barrels. Summary of the invention

[0005] In order to improve the problem of inconsistent concentration of solutions taken from a sealed barrel, the present application provides a multifunctional liquid extraction barrel cover.

[0006] The multifunctional liquid extraction bucket cover provided in this application adopts the following technical solution:

[0007] A multifunctional liquid extraction barrel cover comprises a sealing cover for covering the opening of the sealed barrel, the sealing cover is rotatably connected to a rotating disk, an elastic liquid extraction tube and an air charging tube are eccentrically arranged on the rotating disk, the liquid extraction tube is integrally connected to the tube wall of the air charging tube, and when compressed gas is filled into or discharged from the air charging tube, the liquid extraction tube can be driven to extend or shorten; the sealing cover is provided with an air motor drivingly connected to the rotating disk, and the air motor can drive the liquid extraction tube and the air charging tube to rotate around the axis of the rotating disk through the rotating disk.

[0008] By adopting the above technical solution, when taking liquid from the sealed barrel, the solution in the sealed barrel can be directly extracted through the liquid extraction tube, and the pneumatic motor can drive the rotating disk to rotate on the sealing cover, so that the liquid extraction tube and the gas charging tube can also stir the solution in the sealed barrel in the horizontal direction. During the stirring process, the gas charging tube is filled with gas, and the gas charging tube can effectively support the liquid extraction tube, so that the liquid extraction tube maintains a certain hardness. The pneumatic motor drives the liquid extraction tube and the gas charging tube to move in the sealed barrel through the rotating disk, so that the liquid extraction tube can effectively stir the solution in the sealed barrel.

[0009] Preferably, a plurality of the inflation tubes are provided; at least two of the inflation tubes have inconsistent exhaust rates, so that the inflation tubes can drive the liquid extraction tube to bend when the compressed gas is discharged.

[0010] Preferably, the sealing cover is provided with an air filling and exhausting structure, and during the process of the liquid extraction tube and the air filling tube rotating around the axis of the rotating disk, the air filling and exhausting structure can enable the air filling tube to cyclically fill and exhaust compressed gas.

[0011] By adopting the above technical solution, in the process of stirring the solution in the sealed barrel, by inflating the inflatable tube, the liquid extraction tube can maintain a certain hardness, thereby effectively stirring the solution. When the gas in the inflatable tube is discharged, the inflatable tube and the liquid extraction tube will deform and shrink, so that the liquid extraction tube can stir the solution in the sealed barrel in the vertical direction. During the process of extension and contraction, the rotating disk is rotated, so that the liquid extraction tube can not only stir the solution in the sealed barrel vertically, but also stir it in the horizontal direction at the same time, so that the liquid extraction tube can stir the solution in the sealed barrel in all directions, making the solution in the barrel more uniform, enhancing the mixing effect of the solution in the sealed barrel, and reducing the situation of solution deposition. Among them, since the exhaust rates of at least two inflatable tubes are inconsistent, when the inflatable tube is exhausted, the exhaust efficiency of the inflatable tube on one side of the liquid extraction tube is greater than the exhaust efficiency of the inflatable tube on the other side, resulting in uneven force on both sides of the liquid extraction tube, causing the liquid extraction tube and the inflatable tube to bend. In the process of bending the liquid extraction tube and the inflatable tube, the liquid extraction tube and the inflatable tube will vertically stir the solution in the sealed barrel.

[0012] Preferably, the inflation and exhaust structure includes a socket having one end sealed and slidably connected to the rotating disk, and an inflation cavity, an inflation groove and an exhaust groove are formed on the socket; the inflation groove can connect the inflation cavity with the inflation tube, and the exhaust groove can connect the inflation tube with the outside world; a plurality of inflation grooves and exhaust grooves are alternately arranged around the axis of the rotating disk.

[0013] Preferably, the rotating disk is provided with an elastic aeration pipe, the aeration pipe is integrally connected to the pipe wall of the inflation pipe, and the exhaust groove can connect the inflation pipe and the aeration pipe.

[0014] By adopting the above technical scheme, the aeration pipe can effectively discharge the gas in the inflation pipe. Through the aeration pipe, on the one hand, the gas in the inflation pipe can be discharged more smoothly, and on the other hand, the aeration pipe can discharge the gas into the sealed barrel. It can also increase the strength of the liquid extraction pipe during the stirring process, making the stirring of the solution by the liquid extraction pipe more effective. On the basis of stirring, it further promotes the irregular movement of the solution in the sealed barrel, and enhances the mixing effect of the solution in the sealed barrel.

[0015] When the rotating disk rotates, multiple inflation pipes and aeration pipes correspond to different exhaust grooves. At this time, the inflation pipe and the aeration pipe are connected through the exhaust groove, and the gas in the inflation pipe is discharged into the aeration pipe through the exhaust groove, and then discharged into the sealed barrel by the aeration pipe. The exhaust grooves with different flow areas make the exhaust rates of different inflation pipes inconsistent, so that the force on the inflation pipe and the aeration pipe is uneven, resulting in the rebound force on one side of the liquid extraction pipe being greater than the rebound force on the other side, causing the liquid extraction pipe to bend. The aeration pipe can also increase the exhaust efficiency of the inflation pipe, so that the inflation pipe and the liquid extraction pipe are deformed rapidly. During the continuous rotation of the rotating disk, the inflation pipe is continuously exhausted and inflated, so that the liquid extraction pipe can continue to extend and bend during the rotation process, and the solution in the sealed barrel is stirred vertically and horizontally. At the same time, the aeration pipe aerates the solution in the sealed barrel, accelerates the continuous movement of the solution in the sealed barrel, and further efficiently stirs the solution in the sealed barrel to the maximum extent. In addition, the aeration pipe will rotate and bend horizontally along with the liquid extraction pipe, which can also make the aeration of the aeration pipe more uniform.

[0016] Preferably, the pneumatic motor includes a stator, a rotor is eccentrically arranged inside the stator, a rotating shaft rotatably connected to the stator is provided at the axis center of the rotor, the rotating shaft is drivingly connected to a rotating disk, a plurality of receiving grooves are evenly distributed on the side wall of the rotor along the circumferential direction, blades are slidably connected in the receiving grooves, and an elastic member is connected between the blades and the rotor.

[0017] Preferably, a liquid extraction station is provided on the receiving seat, a liquid extraction channel extending along the axial direction is formed in the rotating shaft, and a liquid extraction cavity connecting the liquid extraction channel and the liquid extraction tube is formed in the rotating disk.

[0018] By adopting the above technical solution, when the inflation motor drives the liquid extraction tube to move to the drainage station, the inflation tube is connected to the inflation groove, and the liquid extraction channel is connected to the liquid extraction chamber. At this time, the solution in the sealed barrel can be effectively extracted. During the drainage process, the solution that can be effectively extracted through the liquid extraction tube can be discharged to the outside of the sealed barrel through the liquid extraction channel, making the overall structure of the barrel cover more compact and complete.

[0019] Preferably, the sealing cover is provided with an electromagnet, and the rotating disk is provided with a pin groove engaged with the moving iron core of the electromagnet; when the moving iron core of the electromagnet is inserted into the pin groove, the inflation tube is connected with the inflation groove, and the liquid extraction tube is located in the liquid extraction station.

[0020] By adopting the above technical solution, the cooperation between the electromagnet and the pin groove can effectively determine the position of the rotating disk, so that the liquid extraction tube can correspond to the liquid extraction station during the liquid extraction process, reducing the damage of components due to operational errors, reducing the number of maintenance times, and extending the overall service life of the barrel cover.

[0021] Preferably, a sealing airbag is provided on the inner wall of the sealing cover close to the sealing barrel, the outer side of the sealing airbag abuts against the sealing barrel, and the inner side of the sealing airbag abuts against the sealing cover.

[0022] By adopting the above technical solution, the sealing airbag can effectively ensure the sealing of the sealing barrel and the sealing cover to a certain extent, thereby reducing the overflow of liquid in the sealed barrel. At the same time, it can also ensure that the air injected into the sealed barrel does not leak out when taking liquid, ensuring normal and effective liquid taking.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. The present application arranges the liquid extraction tube and the gas charging tube on the sealing cover by rotation. When the liquid in the sealed barrel is taken out, the solution in the sealed barrel can be directly extracted through the liquid extraction tube. The liquid extraction tube and the gas charging tube can also stir the solution in the sealed barrel in the horizontal direction. During the stirring process, the gas charging tube is filled with gas. The gas charging tube can effectively support the liquid extraction tube, so that the liquid extraction tube maintains a certain hardness. The rotating disk can drive the liquid extraction tube and the gas charging tube to move in the sealed barrel, so that the liquid extraction tube and the gas charging tube can effectively stir the solution in the sealed barrel.

[0025] 2. The present application sets an inflation chamber and an exhaust groove. During the process of stirring the solution in the sealed barrel, air is inflated into the inflation tube through the inflation joint, so that the liquid extraction tube can maintain a certain hardness, thereby effectively stirring the solution. When the gas in the inflation tube is discharged, the inflation tube and the liquid extraction tube will deform and shrink, allowing the liquid extraction tube to stir the solution in the sealed barrel in the vertical direction. During the process of extension and contraction, the rotating disk is used to rotate, so that the liquid extraction tube and the inflation tube can not only stir the solution in the sealed barrel vertically, but also stir it in the horizontal direction at the same time, so that the liquid extraction tube can stir the solution in the sealed barrel in all directions, making the solution in the barrel more uniform, enhancing the mixing effect of the solution in the sealed barrel, and reducing the sedimentation of the solution;

[0026] 3. The present application sets a receiving seat. When the liquid extraction tube moves to the liquid extraction station, the air-filled tube is connected to the air-filled groove, and the liquid extraction channel is connected to the liquid extraction cavity. At this time, the solution in the sealed barrel can be effectively extracted. When the rotating disk rotates, multiple air-filled tubes and aeration tubes correspond to different exhaust grooves. During the rotation of the rotating disk, when the air-filled tube is connected to the aeration tube through the exhaust groove, the gas in the air-filled tube is discharged into the aeration tube through the exhaust groove, and then discharged into the sealed barrel by the aeration tube. Due to the different exhaust grooves with different flow areas, the exhaust rates of different air-filled tubes are inconsistent, which makes the force on the air-filled tube and the aeration tube uneven, resulting in the rebound force on one side of the liquid extraction tube being greater than the rebound force on the other side, thereby causing the liquid extraction tube to bend. Among them, the aeration tube can also increase the exhaust efficiency of the air-filled tube, so that the air-filled tube and the liquid extraction tube are deformed quickly. And during the continuous rotation of the rotating disk, the aeration tube is constantly vented and inflated, so that the liquid extraction tube can continue to extend and bend during the rotation process, stirring the solution in the sealed barrel in the vertical and horizontal directions. At the same time, the aeration tube can also aerate the solution in the sealed barrel, enhancing the irregular movement of the solution in the sealed barrel, thereby further enhancing the stirring effect of the solution in the sealed barrel. In addition, the aeration tube will rotate and bend horizontally with the liquid extraction pipeline, which can also make the aeration of the aeration tube more uniform.

[0035] The following is combined with Figure 1-7 This application is described in further detail.

[0036] The embodiment of the present application discloses a multifunctional liquid pumping bucket cover. The multifunctional liquid pumping bucket cover comprises a sealing cover 1 for covering the opening of a sealing bucket 2, a rotating disk 4 is rotatably connected to the sealing cover 1, an elastic liquid pumping tube 3 and an air charging tube 31 are eccentrically arranged on the rotating disk 4, the liquid pumping tube 3 and the tube wall of the air charging tube 31 are integrally connected, and when the air charging tube 31 is filled with or discharged with compressed gas, the liquid pumping tube 3 can be driven to extend or shorten; the sealing cover 1 is provided with an air motor 6 drivingly connected to the rotating disk 4, and the air motor 6 can drive the liquid pumping tube 3 and the air charging tube 31 to rotate around the axis of the rotating disk 4 through the rotating disk 4.

[0037] When the solution in the sealed barrel 2 is taken out, the solution in the sealed barrel 2 can be directly extracted through the liquid extraction tube 3, and the pneumatic motor 6 can drive the rotating disk 4 to rotate on the sealing cover 1, so that the liquid extraction tube 3 and the gas filling tube 31 can also stir the solution in the sealed barrel 2 in the horizontal direction. During the stirring process, the gas filling tube 31 is filled with gas, and the gas filling tube 31 can effectively support the liquid extraction tube 3, so that the liquid extraction tube 3 maintains a certain hardness, and the rotating disk 4 can drive the liquid extraction tube 3 and the gas filling tube 31 to move in the sealed barrel 2, so that the liquid extraction tube 3 can effectively stir the solution in the sealed barrel 2. It can be understood that both ends of the liquid extraction tube 3 are open; one end of the gas filling tube 31 is open, and the other end is closed. As an example, the liquid extraction tube 3 and the gas filling tube 31 are made of elastic rubber.

[0038] There are multiple gas filling tubes 31 ; at least two gas filling tubes 31 have different exhaust rates, so that the gas filling tube 31 can drive the liquid extraction tube 3 to bend when the compressed gas is discharged.

[0039] The sealing cover 1 is provided with an air filling and exhausting structure. When the liquid extraction tube 3 and the air filling tube 31 rotate around the axis of the rotating disk 4, the air filling and exhausting structure can make the air filling tube 31 cyclically fill and exhaust compressed gas.

[0040] In the process of stirring the solution in the sealed barrel 2, by inflating the gas tube 31, the liquid extraction tube 3 can maintain a certain hardness, thereby effectively stirring the solution. When the gas in the gas tube 31 is discharged, the gas tube 31 and the liquid extraction tube 3 will deform and shrink, so that the liquid extraction tube 3 can stir the solution in the sealed barrel 2 in the vertical direction. During the process of extension and contraction, the rotating disk 4 is rotated, so that the liquid extraction tube 3 can not only stir the solution in the sealed barrel 2 vertically, but also stir it in the horizontal direction at the same time, so that the liquid extraction tube 3 can stir the solution in the sealed barrel 2 in all directions, making the solution in the barrel more uniform, enhancing the mixing effect of the solution in the sealed barrel 2, and reducing the situation of solution deposition. It can be understood that since the exhaust rates of the gas tubes 31 on the left and right sides of the liquid extraction tube 3 are inconsistent, when the gas tubes 31 on the left and right sides are exhausted, the exhaust efficiency of the gas tube 31 on one side of the liquid extraction tube 3 is greater than the exhaust efficiency of the gas tube 31 on the other side, resulting in uneven force on both sides of the liquid extraction tube 3, causing the liquid extraction tube 3 to bend. During the bending process of the liquid extraction tube 3 and the gas filling tube 31 , the liquid extraction tube 3 and the gas filling tube 31 will vertically stir the solution in the sealed barrel 2 .

[0041] The inflation and exhaust structure includes a receiving seat 11 with one end sealed and slidably connected to the rotating disk 4, and an inflation cavity 12, an inflation groove 112 and an exhaust groove 111 are formed on the receiving seat 11; the inflation groove 112 can connect the inflation cavity 12 with the inflation tube 31, and the exhaust groove 111 can connect the inflation tube 31 with the outside; a plurality of inflation grooves 112 and exhaust grooves 111 are alternately arranged around the axis of the rotating disk 4. As an example, the inflation cavity 12 is connected to an air pump through the inflation joint 5.

[0042] An elastic aeration pipe 32 is disposed on the rotating disk 4 . The aeration pipe 32 is integrally connected to the pipe wall of the inflation pipe 31 . The exhaust groove 111 can connect the inflation pipe 31 and the aeration pipe 32 .

[0043] The aeration tube 32 can effectively discharge the gas in the gas-filled tube 31. On the one hand, it can make the gas in the gas-filled tube 31 discharge more smoothly. On the other hand, the aeration tube 32 can discharge the gas into the sealed barrel 2 to aerate the solution in the sealed barrel 2, and also make the stirring of the solution by the liquid extraction tube 3 more effective. On the basis of stirring, the bubbles generated by aeration promote the irregular movement of the solution in the sealed barrel 2, and enhance the mixing effect of the solution in the sealed barrel 2.

[0044] When the rotating disk 4 rotates, the multiple air-filling tubes 31 and the aeration tubes 32 correspond to different exhaust grooves 111. At this time, the air-filling tubes 31 and the aeration tubes 32 are connected through the exhaust grooves 111, and the gas in the air-filling tubes 31 is discharged into the aeration tubes 32 through the exhaust grooves 111, and then discharged into the sealed barrel 2 by the aeration tubes 32. The exhaust grooves 111 with different flow areas make the exhaust rates of different air-filling tubes 31 inconsistent, so that the air-filling tubes 31 and the aeration tubes 32 are subjected to uneven forces, resulting in the rebound force on one side of the liquid extraction tube 3 being greater than the rebound force on the other side, causing the liquid extraction tube 3 to bend. The aeration tube 32 can also increase the exhaust efficiency of the air-filling tube 31, so that the air-filling tube 31 and the liquid extraction tube 3 are deformed quickly. During the continuous rotation of the rotating disk 4, the inflation tube 31 is alternately connected to the inflation groove 112 and the exhaust groove 111, and the inflation tube 31 is continuously exhausted and inflated, so that the liquid extraction tube 3 can also be continuously extended and bent during the rotation process, and the solution in the sealed barrel 2 is stirred vertically and horizontally. At the same time, the aeration tube 32 aerates the solution in the sealed barrel 2, increasing the irregular movement of the solution in the sealed barrel 2, thereby further enhancing the stirring effect of the solution in the sealed barrel 2. In addition, the aeration tube 32 will rotate and bend horizontally with the liquid extraction tube 3, and the aeration of the aeration tube 32 can also be made more uniform.

[0045] The pneumatic motor 6 includes a stator 61, a rotor 62 is eccentrically arranged in the stator 61, a rotating shaft 63 rotatably connected to the stator 61 is arranged at the axis of the rotor 62, the rotating shaft 63 is drivingly connected to the rotating disk 4, a plurality of receiving grooves 64 are evenly distributed along the circumferential direction on the side wall of the rotor 62, a blade 66 is slidably connected in the receiving groove 64, and an elastic member is connected between the blade 66 and the rotor 62. The rotating disk 4 is driven to rotate by the rotating shaft 63.

[0046] The receiving seat 11 is provided with a pumping station 8, the rotating shaft 63 is provided with a pumping channel 65 extending in the axial direction, and the rotating disk 4 is provided with a pumping cavity 41 connecting the pumping channel 65 and the pumping tube 3. This design makes the overall structure of the barrel cover more compact and complete.

[0047] When the liquid extraction tube 3 moves to the liquid extraction station 8, the gas-filled tube 31 is connected to the gas-filled groove 112, and the liquid extraction channel 65 is connected to the liquid extraction chamber 41. At this time, air is injected into the gas-filled tube 31 through the air pump, so that the gas-filled tube 31 drives the liquid extraction tube 3 to extend, and the solution in the sealed barrel 2 can be effectively extracted. The solution extracted by the liquid extraction tube 3 can be discharged from the sealed barrel 2 through the liquid extraction channel 65.

[0048] An electromagnet 7 is provided on the sealing cover 1, and a pin groove 13 is provided on the rotating disk 4 for engaging with the moving iron core of the electromagnet 7; when the moving iron core of the electromagnet 7 is inserted into the pin groove 13, the inflation tube 31 is connected with the inflation groove 112, and the liquid extraction tube 3 is in the liquid extraction station 8 at this time. It can be understood that the electromagnet 7 is a conventional technical solution in this field, so this specification does not make too much description of it, but it does not affect the understanding and implementation of technical personnel in this field.

[0049] The cooperation between the electromagnet 7 and the pin groove 13 can effectively determine the position of the rotating disk 4, so that the liquid extraction tube 3 can correspond to the liquid extraction station 8 during the liquid extraction process, reducing the damage of components caused by operating errors, reducing the number of maintenance times, and extending the overall service life of the barrel cover.

[0050] A sealing airbag 14 is provided on the inner wall of the sealing cover 1 close to the sealing barrel 2 . The outer side of the sealing airbag 14 abuts against the sealing barrel 2 , and the inner side of the sealing airbag 14 abuts against the sealing cover 1 .

[0051] The sealing airbag 14 can effectively ensure the sealing of the sealing barrel 2 and the sealing cover 1 to a certain extent, thereby reducing the overflow of liquid in the sealing barrel 2. At the same time, it can also ensure that the air injected into the sealing barrel 2 does not leak out when taking liquid, ensuring normal and effective liquid taking.

[0052] The implementation principle of a multifunctional liquid extraction bucket cover in the embodiment of the present application is:

[0053] During the process of taking liquid, the moving iron core of the electromagnet 7 is inserted into the pin groove 13. At this time, the liquid extraction tube 3 is located at the liquid extraction station 8, the gas-filled tube 31 is connected with the gas-filled groove 112, the liquid extraction cavity 41 is connected with the liquid extraction channel 65, and air is injected into the gas-filled tube 31 through the air pump, so that the gas-filled tube 31 drives the liquid extraction tube 3 to extend, and the solution in the sealed barrel 2 can be directly extracted through the liquid extraction tube 3.

[0054] During the stirring process of the solution in the sealed barrel 2, the moving iron core of the electromagnet 7 is withdrawn from the pin slot 13, and the pneumatic motor 6 drives the rotating disk 4 to rotate, so that the inflation pipe 31 and the aeration pipe 32 continuously move alternately between the multiple groups of inflation slots 112 and the exhaust slots 111. When the inflation pipe 31 and the aeration pipe 32 move to the exhaust slot 111, the inflation pipe 31 and the aeration pipe 32 are connected through the exhaust slot 111, and the gas in the inflation pipe 31 is discharged into the aeration pipe through the exhaust slot 111, and then discharged into the sealed barrel 2 through the aeration pipe 32. Figure 4 and 5As shown, since the flow area of ​​the left exhaust groove 111 is smaller than the flow area of ​​the right exhaust groove 111, the exhaust rates of the gas-filled tubes 31 on the left and right sides of the liquid extraction tube 3 are inconsistent, so that the pressures on both ends of the liquid extraction tube 3 are inconsistent, thereby causing the liquid extraction tube 3 to bend to the right. When the gas-filled tube 31 moves to communicate with the gas-filled groove 112, the gas-filled joint 5 inflates the gas-filled tube 31 through the gas-filled cavity 12, so that the gas-filled tube 31 is inflated and extended, driving the liquid extraction tube 3 to extend. In the continuous alternating movement of inflation and exhaust, the liquid extraction tube 3 continuously extends, contracts, and bends, and continuously rotates in the sealed barrel 2, thereby playing a good mixing role on the solution in the sealed barrel 2 in both the horizontal and vertical directions. And on this basis, aeration into the sealed barrel 2 through the aeration tube 32 can further enhance the irregular movement of the solution in the sealed barrel 2, so that the mixing is more thorough.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
