[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model embodiment discloses an automatic flow and temperature control device for laboratory testing.

[0024] The utility model provides Figure 1-3 The shown laboratory test automatic flow and temperature control device includes a frame 1, an outer wall of the frame 1 is fixedly provided with a liquid pump 2, the interior of the liquid pump 2 is connected with a flow tube 3, the pipe mouth of the flow tube 3 passes through the side of the frame 1, and the upper end of the inner wall of the frame 1 is fixedly provided with two symmetrically arranged first cylinders 4, the ends of the two first cylinders 4 are respectively fixedly provided with a temperature detector 5 and a flow tester 6, the flow tester 6 is electrically connected to the liquid pump 2, a placement block 7 is fixedly provided at the bottom of the inner wall of the frame 1, a cross bar 8 is rotatably provided on the inner wall of the placement block 7, a semiconductor cooling plate 9 is fixedly sleeved on the rod wall of the cross bar 8, a plurality of heat dissipation holes are jointly provided on the placement block 7 and the bottom of the frame 1, and a rotating groove for cooperating with the rotation of the semiconductor cooling plate 9 is provided on the top of the placement block 7.

[0025] Before the experiment, the experimental equipment is placed on the placement block 7, and the positions of the temperature detector 5 and the flow tester 6 are adjusted by the first cylinder 4 so that they can cooperate with the experimental equipment. During the experiment, the flow tester 6 can be used to detect the liquid inside the experimental equipment, and the detection signal can be transmitted to the liquid pump 2, so as to cooperate with the flow tube 3 to adjust the suction intensity of the liquid required for the experiment to complete the flow control. At the same time, the use of the semiconductor refrigeration plate 9 can be supported by the cross bar 8 to rotate and switch the cold end and the hot end of the semiconductor refrigeration plate 9, so as to facilitate the control of different temperatures of the experimental materials inside the experimental equipment through the detection of the temperature detector 6, thereby improving the experimental accuracy.

[0026] In order to accurately switch the hot and cold ends of the semiconductor refrigeration plate 9 according to the detected temperature of the temperature detector 5, Figure 1-3As shown, the rod wall of the cross bar 8 is provided with a hot and cold switching mechanism for driving the semiconductor refrigeration plate 9 to rotate, and the hot and cold switching mechanism includes a worm wheel 10 and a worm 11. The worm 11 is rotatably arranged inside the placement block 7 and is arranged in cooperation with the worm wheel 10. The worm wheel 10 is fixedly sleeved on the outer side of the cross bar 8. A groove is provided on one side of the bottom of the placement block 7. A ratchet 12 is fixedly sleeved on the rod wall of the worm 11. A through hole for rotating with the ratchet 12 is provided between the groove and the inner wall of the placement block 7. A second cylinder 13 is fixedly provided at the bottom of the frame 1. The temperature detector 5 is electrically connected to the second cylinder 13. The second cylinder 13 is a self-resetting cylinder. The piston rod of the second cylinder 13 penetrates into the groove and is fixedly provided with a vertical plate 14. A plurality of support rods 15 arranged at intervals are fixedly provided on the outer wall of the vertical plate 14. A ratchet 16 is rotatably sleeved on the rod wall of the support rod 15. The ratchet 16 is arranged in cooperation with the ratchet 12. The lower end of the ratchet 16 is in contact with a limit rod 17, and the limit rod 17 is fixedly connected to the vertical plate 14.

[0027] When the temperature detector 5 detects the experimental temperature and finds that the temperature needs to be adjusted, the temperature detector 5 transmits the detection signal to the second cylinder 13, so that the second cylinder 13 pushes the vertical plate 14. At this time, multiple ratchets 16 push the ratchet 12 with the support of the limit rod 17, so that the ratchet 12 rotates and drives the worm 11 to rotate. Through the engagement of the worm 11 and the worm wheel 10, the worm wheel 10 can drive the cross bar 8 to rotate. At this time, the semiconductor refrigeration plate 9 can be driven to complete the switching between the cold end and the hot end. At the same time, since the second cylinder 13 is a self-resetting cylinder, it can quickly return to its original position after the second cylinder 13 completes a pushing work. During the returning process, the ratchets 16 can rotate around the support rod 15. At this time, the ratchets 16 contact the outer wall of the ratchet 12 and cannot push the ratchet 12, so that the ratchet 12 cannot drive the semiconductor refrigeration plate 9 to rotate, thereby ensuring the stable operation of the semiconductor refrigeration plate 9 and improving the experimental accuracy.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
