[0031] Please see Figure 1-3 This utility model provides a technical solution: a negative pressure main unit for feeding a rat cage, including a base plate 1, an assembly box 2 mounted on the base plate 1, a negative pressure fan 3 installed inside the assembly box 2, a differential pressure switch 4 mounted on the negative pressure fan 3, a pneumatic valve 5 installed at the front end of the negative pressure fan 3, and an air duct 6 mounted on the negative pressure fan 3. The air duct 6 passes through the assembly box 2 and connects to a dust collection bin 7, and an air guide pipe 8 is mounted on the dust collection bin 7. The air guide pipe 8 extends and connects to a storage tank and a filling mechanism, respectively. By installing a differential pressure switch, the pressure difference between the inlet and outlet of the fan is detected, thereby determining the operating status of the fan.
[0032] A support bracket 9 is provided on the base plate 1, and the dust collection bin 7 abuts against the support bracket 9.
[0033] The dust collection bin 7 includes an upper dust bin 71 and a lower dust bin 72. The supporting bracket 9 includes a circular abutment frame 91 and a support frame 92. The circular abutment frame 91 is connected to the support frame 92. The support frames 92 form a receiving groove by surrounding each other. The upper dust bin 71 is snapped onto the circular abutment frame 91. The lower dust bin 72 is located at the bottom of the upper dust bin 71 and is located in the receiving groove. The bottom of the lower dust bin 72 is provided with casters 10.
[0034] The bottom of the upper dust bin 71 is funnel-shaped, and the bottom of the upper dust bin 71 extends into the lower dust bin 72.
[0035] The assembly housing 2 is equipped with a control board 11, and the control board 11 is equipped with a pulse solenoid valve 12. The pulse solenoid valve controls the opening and closing of the pneumatic valve.
[0036] The dust collection bin 7 is equipped with an air inlet 13, which is located at the bottom of the upper dust bin 71. The air guide pipe 8 is connected to the air inlet 13, and the air duct 6 is connected to the top of the upper dust bin 71. This allows dust in the air to pass through the bottom first, fall off due to gravity, and then be drawn into the air by the fan, preventing the drawn-out dust from being discharged into the environment.
[0037] Working principle: By connecting the negative pressure unit and the dust collection bin, which includes an upper dust bin and a lower dust bin, the upper dust bin is placed on a circular support frame. The bottom of the upper dust bin is funnel-shaped and extends into the lower dust bin. This structure ensures that after the negative pressure unit is running, the dust is collected in the dust collection bin and will not be discharged into the environment, affecting the growth of the experimental mice and thus the experimental results.
