The bubbles and vortices will increase the contact area between the battery solution and the outside air, thereby increasing the possibility of oxidation. At the same time, the generated bubbles may be stored inside the battery solution, thereby prolonging the time for the battery solution to be oxidized by the air and affecting the quality of the battery solution. Utility Model Content

[0004] The utility model aims to provide a stirring device for liquid mixture, so as to solve the technical problem in the prior art that the solution is easily oxidized by air due to poor sealing during the stirring process of battery mixed liquid.

[0005] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

The device also comprises a transmission mechanism, a sliding sleeve mechanism and a sealing mechanism, wherein the transmission mechanism comprises a motor connected to the upper end of the U-shaped support plate, a transmission shaft is coaxially fixed to the output end of the motor, and a first stirring component is arranged below the transmission shaft; the sliding sleeve mechanism comprises a sliding tube, which is slidably sleeved on the transmission shaft, and the cross-sections of the sliding tube and the transmission shaft are regular polygons that match each other; the sealing mechanism comprises a positioning tube and an inner ring plate, wherein the positioning tube is slidably sleeved on the sliding tube, and a plurality of connecting plates are equidistantly fixed around the side surface of the positioning tube, the inner ring plate is fixedly connected to the positioning tube through the connecting plate, an outer ring plate is arranged around the outer side of the inner ring plate, and the outer ring plate matches the inner wall of the bearing cylinder, and glass plates are fixedly filled between every two groups of the connecting plates.

[0007] As a further solution of the utility model: the upper end of the sliding tube is coaxially fixedly connected with a first magnet, the upper end of the positioning tube is coaxially fixedly connected with a second magnet, and the U-shaped support plate is made of metal.

[0009] As a further solution of the utility model: a limiting ring is fixedly connected to the outer side of the inner ring plate, a limiting groove matched with the limiting ring is opened on the inner side of the outer ring plate, a groove body is opened on the lower surface of the limiting ring, and balls are filled inside the groove body, and the lower end of the ball is in contact with the limiting groove.

[0010] As a further solution of the utility model: a plurality of stirring plates are equidistantly and fixedly connected to the lower end of the positioning tube.

[0011] As a further solution of the utility model: the lower end of the transmission shaft is fixedly connected to a telescopic rod, the cross-section of the telescopic rod is polygonal, the inside of the telescopic rod is fixedly connected to a spring, a plurality of the first stirring components are coaxially fixedly connected to corresponding positions of the telescopic rod, the lower end of the telescopic rod is fixedly connected to a second stirring component, the telescopic rod is rotatably connected to a support block near the lower end, support rods are fixedly connected on both sides of the support block, and the end of the support rod away from the support block is fixedly connected to the inner wall of the bearing cylinder.

[0012] Beneficial effects of the utility model:

[0013] 1. In the utility model, after the loading is completed, the sealing mechanism is driven to slide downward along the inner wall of the bearing cylinder. It is observed through the glass plate that the lower surface of the sealing mechanism has contacted the liquid to be mixed. The fixed knob is rotated to squeeze the sliding tube, thereby realizing the positioning of the positioning tube. The exhaust knob is rotated to ensure that the mixed liquid is in the sealed environment surrounded by the sealing mechanism and the bearing cylinder. The sealing mechanism can adjust its own position according to the volume of the liquid, thereby adjusting the storage capacity. When the volume of the liquid to be stirred is different, the device can still ensure the sealing effect, thereby reducing the possibility of generating bubbles, thereby reducing the oxidation rate of the liquid to be stirred, and it is more flexible to use.

[0014] 2. According to the utility model, when the stirred liquid needs to be output through the valve, the volume of the liquid will become smaller, and the sealing mechanism and the sliding sleeve mechanism will move downward under the action of the liquid and its own gravity. When the volume of the liquid is reduced to a certain extent, the sealing mechanism will squeeze the telescopic rod. Under the squeezing of the sealing mechanism and the support block, the total length of the telescopic rod is reduced, so that the sealing mechanism changes its position as the volume of the liquid decreases, thereby ensuring the sealing effect of the device. When the volume of the liquid is reduced to affect the output of the liquid, the exhaust knob can be rotated to allow air to enter the bottom of the sealing mechanism through the exhaust hole, thereby ensuring that the liquid can be output normally, thereby maximizing the sealing effect of the liquid and reducing the oxidation rate.

[0028] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0029] When in use, the sliding tube 301 is moved upward along the transmission shaft 202, so that the first magnet 302 is adsorbed on the bottom of the U-shaped support plate 8 by magnetic force, thereby realizing the positioning of the sliding tube 301, and the positioning tube 401 is moved upward along the sliding tube 301, so that the second magnet 402 is adsorbed under the first magnet 302 by magnetic force, thereby ensuring that during the feeding process, the sealing mechanism 4 will not be blocked inside the supporting cylinder 1.

The supporting cylinder 1 is responsible for providing an implementation environment suitable for stirring, and can also be used as a storage container for the liquid after stirring is completed, and the output of the stirring liquid is realized through the valve 5;

[0030] After the loading is completed, the positioning tube 401 is pushed and pulled downward to drive the outer ring plate 407 to slide downward along the inner wall of the bearing cylinder 1. Through the glass plate 404, it is observed that the lower surface of the sealing mechanism 4 has contacted the liquid to be mixed. The fixed knob 413 is rotated to squeeze the sliding tube 301, thereby realizing the positioning of the positioning tube 401. The exhaust knob 409 is rotated to ensure that the mixed liquid is in the sealed environment surrounded by the sealing mechanism 4 and the bearing cylinder 1. The sealing mechanism 4 can adjust its own position according to the volume of the liquid, thereby adjusting the storage capacity, which is more flexible to use.

[0031] During the stirring process, the motor 201 drives the transmission shaft 202 to rotate, the transmission shaft 202 drives the telescopic rod 203 to rotate, the telescopic rod 203 drives the first stirring component 204 and the bottom cylinder 207 to rotate, and the bottom cylinder 207 drives the second stirring component 206 to rotate, thereby achieving mixing and stirring of the liquid. When the stirred liquid needs to be output through the valve 5, the volume of the liquid will become smaller at this time, and the sealing mechanism 4 will move downward along with the sliding tube 301 under the action of the liquid. When the liquid volume is reduced to a certain extent, the sealing mechanism 4 will squeeze the telescopic rod 203, so that the total length of the telescopic rod 203 is reduced under the squeezing of the sealing mechanism 4 and the support block 7, thereby achieving the sealing mechanism 4 to change its position as the liquid volume decreases, thereby ensuring the sealing effect of the device. When the liquid volume is reduced to affect the liquid output, the exhaust knob 409 can be rotated to allow air to enter the bottom of the sealing mechanism 4 through the exhaust hole 410, thereby ensuring that the liquid can be output normally.
