[0008] As an improvement, the exhaust mechanism includes a ventilation duct fixedly connected to the upper end of the control room and communicating with the fume hood, and a guide fan fixedly connected to the upper end of the fume hood, with the input end of the guide fan fixedly connected to the ventilation duct.

[0009] As an improvement, the bottom surface of the control room is provided with a switch pedal that cooperates with the liquid discharge pump, and a switch window that cooperates with the switch pedal is provided on one side of the injection platform.

[0010] As an improvement, a liquid level sensor is installed inside the fixed liquid tank.

[0011] As an improvement, the bottom of the injection platform is equipped with casters at all four corners, and a push-pull handle is provided on one side of the injection platform.

[0012] The advantages of this utility model compared with the prior art are: the liquid dispensing mechanism and the liquid filling mechanism can realize the rapid filling and filling of the fixative; during the filling process, the exhaust mechanism rapidly draws the fume hood into a negative pressure state, which quickly draws out the toxic gases volatilized in the fixative, and then purifies and filters them through the activated carbon filter box to prevent workers from inhaling them.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] like Figures 1 to 2As shown, a fixed liquid filling machine includes a filling platform 1 and a fixed liquid tank 2. The filling platform 1 has casters 17 at each of its four corners. A push-pull handle 18 is located on one side of the filling platform 1. A water basin 4 and a filling faucet 3 are mounted on the filling platform 1. A control chamber 19 is located inside the filling platform 1. A liquid addition pump 6 is fixedly connected to one side of the control chamber 19. A liquid addition pipe 10 is connected between the liquid addition pump 6 and the fixed liquid tank 2. A liquid outlet pump 5 is fixedly connected to the control chamber 19. A suction pipe 9 is fixedly connected between the input end of the liquid outlet pump 5 and the fixed liquid tank 2. A liquid outlet pipe 8 is fixedly connected between the output end of the liquid outlet pump 5 and the filling faucet 3. A liquid level sensor is located inside the fixed liquid tank 2. A switch pedal 15, which cooperates with the liquid outlet pump 5, is located on the bottom surface of the control chamber 19. A switch window 16, which cooperates with the switch pedal 15, is located on one side of the filling platform 1.

[0018] The fume hood 13 has evenly arranged ventilation holes 14 on one side. The bottom surface of the control room 19 is provided with an activated carbon filter box 12. An exhaust mechanism is provided between the activated carbon filter box 12 and the fume hood 13. The exhaust mechanism includes a ventilation duct 11 fixedly connected to the upper end of the control room 19 and communicating with the fume hood 13. A guide fan 7 is fixedly connected to the upper end of the fume hood 13. The input end of the guide fan 7 is fixedly connected to the ventilation duct 11.

[0019] The fume hood 13 is equipped with a liquid filling switch that works with the liquid filling pump 6 and a fan switch that works with the flow guide fan 7 on one side. At the same time, the fume hood 13 is also equipped with a low liquid indicator light and a full liquid indicator light that work with the liquid level sensor in the fixed liquid tank 2 on one side.

[0020] In practical use, the liquid pump 6 is started to store the fixative in the fixative tank 2. The amount of fixative in the tank 2 can be determined by observing the full liquid indicator and the low liquid indicator. When it is necessary to inject the fixative, the switch pedal 15 is stepped on to start the liquid pump 5 to draw the fixative from the tank 2. The fixative is then injected through the injection faucet 3. A water basin 4 is used to prevent the fixative from accumulating further and to prevent excessive overflow, which would be inconvenient for cleaning. The air guide fan 7 is started to extract air from the fume hood 13, creating a negative pressure state inside the fume hood 13. This quickly draws out the toxic gases volatilized during the injection process and passes them into the activated carbon filter box 12 for filtration and purification, preventing the toxic gases from being inhaled by the staff and affecting their health.
