[0017] Embodiment 1

[0018] Reference Figures 1 to 3 , a laboratory stirring device, including a frame 1, a stirring shaft 2 and a rotating mechanism 3 arranged on the frame 1. The stirring shaft 2 is detachably connected to the rotating mechanism 3. A chamber 23 is provided inside the stirring shaft 2. It further includes a temperature detection module 6 installed in the chamber 23. A feeding channel 21 communicating with the chamber 23 is provided on the side of the stirring shaft 2, and a discharging channel 22 communicating with the chamber 23 is provided at the bottom of the stirring shaft 2;

[0019] When the rotating mechanism 3 drives the stirring shaft 2 to rotate, the material enters the chamber 23 from the feeding channel 21 and flows out from the discharging channel 22 after flowing through the temperature detection module 6.

[0020] In this design, place the peripheral container containing the material under the stirring shaft 2, and then drive the rotation of the stirring shaft 2 through the rotating mechanism 3, so that the material in the peripheral container enters the chamber 23 from the feeding channel 21 on the side of the stirring shaft 2. And as the pressure in the chamber 23 increases, the material flows out from the discharging channel 22 after flowing through the temperature detection module 6, and the temperature of the material is measured under the action of the temperature detection module 6. During the process of the rotating mechanism 3 driving the stirring shaft 2 to rotate, the flow direction of the material keeps cycling this process to measure the temperature of the material; in this way, there is no need for the staff to manually measure the temperature frequently to pay attention to the temperature change at any time, and moreover, it can avoid the situation that the rotation of the stirring shaft 2 causes harm to people's hands during stirring.

[0021] In this embodiment, the feeding channel 21 is a through groove with an arc-shaped structure, and the feeding channel 21 bends from the end communicating with the chamber 23 along the rotation direction of the stirring shaft 2 to the side of the stirring shaft 2.

[0022] Specifically, during the process of the rotating mechanism 3 driving the stirring shaft 2 to rotate, in order to make the material in the peripheral container better enter the chamber 23, the feeding channel 21 is set as a through groove with an arc-shaped structure and is bent along the rotation direction of the stirring shaft 2. In this way, when the stirring shaft 2 rotates, the material can cut into the feeding channel 21 along the bent direction of the feeding channel and be guided to the chamber 23 of the stirring shaft 2.

[0023] Preferably, there are multiple feeding channels 21, and they are arranged in a circumferential array around the axis of the stirring shaft 2. Multiple feeding channels 21 can allow more material to enter the chamber 23 to ensure the uniformity of the overall temperature of the material to be detected.

[0024] More preferably, it further includes a guide plate 4 arranged on the side of the stirring shaft 2. The guide plate 4 is located on one side of the feeding port of the feeding channel 21 and corresponds to the feeding port one by one;

[0025] When the rotating mechanism 3 drives the stirring shaft 2 to rotate, the guide plate 4 is used to guide the solution into the feed channel 21.

[0026] Specifically, during the process that the rotating mechanism 3 drives the stirring shaft 2 to rotate, since the stirring shaft 2 rotates rapidly, in order to make the materials in the peripheral container enter the chamber 23 more easily, a guide plate 4 is arranged on the side surface of the stirring shaft 2. The guide plate 4 blocks the materials and guides the materials to the feed channel 21, so that the materials can better enter the chamber 23 from the feed inlet 211 of the feed channel 21.

[0027] Preferably, there are multiple discharge channels 22, which are vertically arranged at the bottom of the stirring shaft 2. By arranging multiple vertically arranged discharge channels 22 at the bottom of the stirring shaft 2, during the rotation of the stirring shaft 2, the materials can flow out of the chamber 23 better, improving the smoothness of the circulating flow of the materials.

[0028] The rotating mechanism 3 includes a rotating motor 31 arranged on the frame 1 and a connecting shaft 32 arranged at the output end of the rotating motor 31. The connecting shaft 32 is provided with threads inside, and the stirring shaft 2 is in threaded connection with the connecting shaft 32; the rotation direction of the threads is opposite to the driving direction of the rotating motor 31.

[0029] Furthermore, the rotating motor 31 is used to drive the rotation of the connecting shaft 32, thereby driving the rotation of the stirring shaft 2. Moreover, the direction of the threads is opposite to the driving direction of the rotating motor 31, so that the self-tightening of the stirring shaft 2 can be completed, and the stirring shaft 2 can be conveniently replaced.

[0030] Preferably, a plurality of stirring blades 5 are arranged on the stirring shaft 2. By arranging a plurality of stirring blades 5 on the stirring shaft 2, the mixing degree of the materials during the stirring process can be improved.

[0031] More preferably, the temperature detection module 6 is a temperature sensor 61. The materials enter the chamber 23 from the side feed channel 21, flow through the temperature sensor 61, and then flow out from the discharge channel 22 at the bottom of the stirring shaft 2. The temperature sensor 61 is used to detect the temperature of the flowing-in materials.

[0032] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements or deformations can still be made, and these improvements or deformations should also be regarded as the protection scope of the present invention.
