Therefore, the existing electric constant temperature incubators need to be improved to a certain extent. Utility Model Content

[0025] The specific implementation method is as follows: through the filter screen 9, the transmission device 15 and the first transmission rod 16, two motors 13 are used to drive the transmission device 15 to rotate synchronously through the fixed rod 14, and at this time, the transmission device 15 drives the first transmission rod 16 and the exhaust fan 17 to rotate, so that the two sets of exhaust fans 17 are started synchronously to complete the internal ventilation of the electric constant temperature incubator;

[0026] This makes it convenient for the staff to quickly ventilate the inside of the electric constant temperature incubator, improves the ventilation efficiency of the entire device, and at the same time, filters the air during the ventilation process through the filter net 9, thereby ensuring the stability of the electric constant temperature incubator during the ventilation process and increasing the practicality of the entire device.

[0027] See also Figure 1-4The utility model provides a technical solution: a drawer-type electric constant temperature incubator, a motor 13 is arranged on one side of the partition 11, and the output shaft of the motor 13 is connected to the fixed rod 14 through a coupling, the outer wall of the fixed rod 14 is arranged with a transmission device 15, and the inner wall of the transmission device 15 is arranged with a No. 1 transmission rod 16, the outer wall of the No. 1 transmission rod 16 is fixedly connected to an exhaust fan 17, the inner wall bearing of the partition 11 is connected to a No. 2 transmission rod 20, and the outer wall of the No. 2 transmission rod 20 is fixedly connected to a transmission gear 21, the outer wall of the transmission gear 21 is meshedly connected to a gear rod 22, and one side of the gear rod 22 is fixedly connected to a connecting rod 25, and the upper part of the connecting rod 25 is fixedly connected to a sealing plate 26.

[0028] The outer wall of the fixed rod 14 is fixedly connected to a first gear 18, and the outer wall of the first gear 18 is meshedly connected to a half gear ring 19, the half gear ring 19 forms a rotating structure through the first gear 18, and the inner wall of the half gear ring 19 is fixedly connected to a second transmission rod 20;

[0029] The transmission gear 21 forms a rotating structure with the half gear ring 19 through the second transmission rod 20, and there are two gear rods 22. The two gear rods 22 form a relative motion through the transmission gear 21, and a slide plate 23 is fixedly connected to one side of the bottom end of the gear rod 22;

[0030] A slide groove 24 is formed through the outer wall of the fixing frame 10, and a slide plate 23 is slidably connected to the inner wall of the slide groove 24. The inner wall of the slide groove 24 and the outer wall of the slide plate 23 match each other in shape and size.

At the same time, the motor 13 drives the two transmissions 15 to rotate synchronously through the fixing rod 14.

[0037] Thereby, the transmission rod No. 1 16 is driven to rotate through the transmission device 15, and then the exhaust fan 17 installed on the inner wall of the support plate 12 is driven to rotate through the No. 1 transmission rod 16, and the exhaust fan 17 arranged inside the two fixed frames 10 is used to ventilate the inside of the electric constant temperature incubator to ensure the stability of subsequent cultivation in the electric constant temperature incubator, and then the ventilation air is filtered through the filter net 9 installed on the inner wall of the cabinet 1.
