Description

Technical Field

[0001] The utility model relates to the technical field of magnetic stirring devices, and particularly relates to a magnetic stirring device with a quick-release function. Background Art

[0002] A magnetic stirring device can stir a liquid. During the process of using magnetic stirring, the stirring of the liquid is achieved by the rotation of a stirring bar. The stirring bar is divided into a fixed type and a non-fixed type. The position of the fixed stirring bar is relatively stable and is not prone to deviation or jumping. This stability helps to achieve a more uniform and consistent stirring effect.

[0003] When the staff finishes stirring the liquid, it is usually necessary to clean the stirring utensils. However, the fixed stirring bar is often difficult to disassemble. This not only makes it inconvenient for the staff to disassemble and clean it, reducing the cleaning efficiency, but also weakens the cleaning effect of the stirring bar by the user. As a result, there may be some stains remaining in the dead corner at the bottom of the stirring bar, thus contaminating the liquid to be stirred subsequently. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the drawbacks existing in the prior art, and a magnetic stirring device with a quick-release function is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A magnetic stirring device with a quick-release function includes a magnetic drive assembly, a weighing cup, and a stirring bar. The weighing cup is placed on the top of the magnetic drive assembly, and the stirring bar rotates inside the weighing cup. A circular groove is opened at the bottom of the inner cavity of the weighing cup. A rotating shaft is vertically and rotatably arranged upward in the middle of the circular groove. A limiting column is fixedly arranged above the rotating shaft, and the stirring bar is fixedly sleeved on the limiting column. An activity cavity is horizontally penetrated inside the limiting column, and a plurality of clamping blocks for clamping the stirring bar are movably arranged in the activity cavity.

[0007] In addition, a preferred structure is that the bottom end of the rotating shaft is rotatably installed at the bottom of the weighing cup through a bearing.

A limiting cavity is vertically penetrated in the middle of the stirring bar. The limiting cavity is adapted to the limiting column, and the limiting column is in the shape of a "square column".

[0009] In addition, a preferred structure is that a clamping block is movably arranged inside the movable cavity. There are two clamping blocks, and both are located on both sides of the movable cavity and move. The two clamping blocks are arranged back to back with each other. Mounting seats are fixedly arranged on the back surfaces of both clamping blocks, and a spring is connected between the two mounting seats.

[0010] In addition, a preferred structure is that auxiliary cavities are communicated and opened on the upper and lower sides of the movable cavity inside the limiting column. Extension parts are fixedly and adaptively arranged on the upper and lower sides of both clamping blocks corresponding to the auxiliary cavities.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0021] Referring to Figures 1-5 , a magnetic stirring device with a quick-release function, including a magnetic drive assembly 1, a weighing cup 2 and a stirring bar 3. The weighing cup 2 is placed on the top of the magnetic drive assembly 1, and the stirring bar 3 rotates inside the weighing cup 2. An annular groove 21 is opened at the bottom of the inner cavity of the weighing cup 2. A rotating shaft 4 is vertically and rotatably arranged upward in the middle of the annular groove 21. A limiting post 42 is fixedly arranged above the rotating shaft 4, and the stirring bar 3 is fixedly sleeved on the limiting post 42. A movable cavity 421 is horizontally penetrated inside the limiting post 42, and a plurality of clamping blocks 5 for clamping the stirring bar 3 are movably arranged in the movable cavity 421. It should be noted that the stirring bar 3 can be driven to rotate by the magnetic drive assembly 1. The specific structures and working methods of the magnetic drive assembly 1 and the stirring bar 3 are all existing technologies publicly available on the market at present. They are all common knowledge well-known to those skilled in the art and do not belong to the main technical problems to be solved in this technical solution. Therefore, they will not be elaborated in this invention.

[0022] Among them, the bottom end of the rotating shaft 4 is rotatably installed at the bottom of the weighing cup 2 through a bearing. The top end of the rotating shaft 4 is fixedly provided with a support seat 41 for supporting the stirring bar 3. The support seat 41 is arranged in an "arc" shape and is adapted to the stirring bar 3, and a limiting post 42 is fixedly and vertically arranged upward on the top of the support seat 41. Through the setting of the support seat 41, the stirring bar 3 can be supported, so as to ensure that the bottom of the stirring bar 3 does not contact the bottom wall of the weighing cup 2 during rotation, thereby reducing the friction force received by the stirring bar 3 during rotation.

[0023] Among them, a protective sleeve is fixedly sleeved outside the stirring bar 3. A limiting cavity 31 is vertically penetrated through the middle of the stirring bar 3. The limiting cavity 31 is adapted to the limiting post 42, and the limiting post 42 is in the shape of a "square post". The bottom of the rotating shaft 4 is arranged inside the bottom of the weighing cup 2 through a bearing. The rotating shaft 4 itself is not connected to a driving mechanism, but the stirring bar 3 rotates through the magnetic drive assembly 1, so as to drive the limiting post 42, the support seat 41 and the rotating shaft 4 to rotate synchronously through the rotation of the stirring bar 3.

[0024] Among them, a clamping block 5 is movably arranged inside the movable cavity 421. There are two clamping blocks 5, and both of the two clamping blocks 5 are movable on both sides of the movable cavity 421. The two clamping blocks 5 are arranged back to back with each other. Mounting seats 6 are fixedly arranged on the backs of both clamping blocks 5, and a spring 61 is connected between the two mounting seats 6. And sealing sleeves are arranged on the outer sides of the movable cavity 421 and the outer sides of the clamping blocks 5. Through the arrangement of the sealing sleeves, when the clamping block 5 extends out of the limiting column 42, the sealing performance of the movable cavity 421 inside the limiting column 42 can be ensured. When the user needs to remove the stirring bar 3, although the external liquid will enter the movable cavity 421 as the clamping block 5 is pressed inward, but at this time it has come to the time for disassembling and cleaning the components, so the sealing performance does not need to be considered at this time.

[0025] Among them, a positioning member 8 is fixedly arranged in the middle of the movable cavity 421, and mutually repulsive magnetic blocks are fixedly laid on the backs of both clamping blocks 5. Through the arrangement of the magnetic blocks, the two clamping blocks 5 can move outward by the repulsive magnetic force, and through the arrangement of the positioning member 8, it can be ensured that when the user presses the two clamping blocks 5 inward, the clamping blocks 5 will not move inward too much distance.

[0026] Among them, auxiliary cavities 422 are communicated and opened on the upper and lower sides of the movable cavity 421 inside the limiting column 42. Extension members 50 are fixedly and adaptively arranged on the upper and lower sides of both clamping blocks 5 corresponding to the auxiliary cavities 422. A plurality of guide posts 7 are horizontally and fixedly arranged in the auxiliary cavities 422, and the extension members 50 are all movable on the guide posts 7. Through the arrangement of the guide posts 7 and the extension members 50, it can be ensured that the clamping block 5 remains stable during the moving process.

[0027] Among them, the height of the limiting column 42 is greater than the height of the stirring bar 3. When the stirring bar 3 is sleeved on the limiting column 42, the top end of the limiting column 42 extends out from the top of the limiting cavity 31, and the clamping block 5 is clamped above the stirring bar 3. Through the arrangement of the clamping block 5, the clamping of the stirring bar 3 can be realized.

[0028] In this embodiment, when the user needs to stir the liquid, the weighing cup 2 can be placed above the magnetic drive assembly 1 first, and then the stirring bar 3 is inserted into the upper part of the limiting column 42 inside the weighing cup 2. When the stirring bar 3 is located on the limiting column 42, the clamping of the stirring bar 3 can be realized through the arrangement of the clamping block 5, so that the stirring bar 3 can be fixedly assembled on the limiting column 42. And through the arrangement of the support seat 41, the support of the stirring bar 3 can be realized, so that the stirring bar 3 does not contact the bottom wall of the weighing cup 2 during the rotation process, thereby reducing the friction force received by the stirring bar 3 during the rotation process.

[0029] Furthermore, the rotation of the stirring bar 3 can be achieved through the magnetic driving assembly 1. When the stirring bar 3 rotates, the rotating shaft 4, the support base 41, and the limiting column 42 all rotate synchronously with the stirring bar 3, thereby ensuring the stability of the stirring bar 3 during rotation.

[0030] Furthermore, when the user installs the stirring bar 3 on the limiting column 42, the clamping blocks 5 on both sides will move outward due to the elastic force of the spring 61, so that the limiting member 42 can be clamped by the clamping blocks 5. When the user needs to remove the stirring bar 3, just press the clamping blocks 5 on both sides inward to compress the spring 61. In addition, slopes are provided at the tops of the clamping blocks 5 on both sides, which facilitates the user to press the clamping blocks 5 on both sides inward when installing the stirring bar 3 on the limiting column 42.

[0031] In the present utility model, through the mutual clamping between the clamping block 5 and the clamping cavity 32, the stirring bar 3 can be fixedly installed on the limiting column 42, thereby realizing the fixed stirring of the stirring bar 3, ensuring the stability of the stirring bar 3 during rotation, improving the stirring effect, and this installation method can realize the quick disassembly and assembly of the stirring bar 3, which is convenient for the user to remove and clean after stirring, so as to avoid stains remaining in the dead corners at the bottom of the stirring bar 3, thereby preventing the subsequent stirred liquid from being contaminated.

[0032] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present utility model.
