In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0028] In addition, the term "same" does not mean that the parts must be absolutely the same, but slight differences are allowed. The term "vertical" only means that the positional relationship between the parts is more vertical than "parallel", and does not mean that the structure must be completely vertical, but can be slightly tilted.

[0029] See also Figure 1-5 The utility model provides a technical solution: an air purification device for a chemical laboratory, comprising a mounting shell 1, an air inlet 101 and an air outlet 102 are respectively arranged at both ends of the mounting shell, and a dust removal chamber 2 for removing dust from the gas, a disinfection chamber 3 for disinfecting the gas, and a heating chamber 4 for heating the gas are sequentially arranged between the air inlet 101 and the air outlet 102.

[0030] In this solution, the air inlet 101, the dust removal chamber 2, the disinfection chamber 3, the heating chamber 4 and the air outlet 102 are connected to form a connected space, and the air inlet 101 and the air outlet 102 serve as connecting ports between the mounting shell 1 and the outside world, and air is input into the mounting shell 1 and output out of the mounting shell 1 through the air inlet 101 and the air outlet 102.

[0031] Wherein, a fan is installed in the air inlet 101;

[0032] When in use, the fan blades in the fan 5 rotate to suck the air around the installation shell 1 into the installation shell 1, and the air is discharged through the air outlet 102 after passing through the dust removal chamber 2, the disinfection chamber 3 and the heating chamber 4.

[0033] Among them, the dust particles contained in the air are removed through the dust removal chamber 2; the air containing toxic and harmful gases is disinfected by the disinfection chamber 3; the air is heated and discharged by the heating chamber 4, so that the laboratory is not easy to be humid. After a series of treatments in the dust removal chamber 2, the disinfection chamber 3 and the heating chamber 4, the pollution of the air to the surrounding environment is effectively reduced.

[0034] In this embodiment, an anode plate 201 and a cathode plate 202 are respectively disposed on opposite sides of the dust removal chamber 2 , and a control switch 6 electrically connected to the anode plate 201 and the cathode plate 202 is disposed on the mounting shell 1 .

[0035] The air entering the dust removal chamber 2 is dust-removed by the anode plate 201 and the cathode plate 202. An electrostatic area is formed between the anode plate 201 and the cathode plate 202 when energized. When the air enters the electrostatic area in the dust removal chamber 2, the dust in the air is electrically separated by the electrostatic field. After the dust combines with negative ions and carries negative charge, it tends to discharge and deposit on the surface of the anode plate 201, thereby separating the dust from the air.

[0036] The control switch 6 is used as a power switch for the anode plate 201 and the cathode plate 202. When dust is adsorbed on the anode plate 201, the control switch 6 is turned off to disconnect the power supply to the anode plate 201 and the cathode plate 202. The dust loses the influence of ions and leaves the surface of the anode plate 201.

[0037] Mounting grooves 8 are provided on the inner walls on both sides of the dust removal chamber 2, and connecting rods 801 are provided in the two mounting grooves 8. The relatively close ends of the two connecting rods 801 are penetrated by the mounting grooves 8 and are respectively connected to the anode plate 201 and the cathode plate 202, and the other ends are provided with limiting plates 802. The diameter of the limiting plate 802 is larger than the diameter of the notch of the mounting groove 8. Springs 803 are sleeved on the two connecting rods 801, and the two ends of the springs 803 are respectively abutted against the side walls of the mounting groove 8 and the side walls of the limiting plate 802.

[0038] In the natural state, the spring 803 is unfolded in the natural state, and at this time, the anode plate 201 and the cathode plate 202 are both in contact with the inner wall of the dust removal chamber 2;

[0039] The speed of the fan can directly affect the air flow speed between the anode plate 201 and the cathode plate 202. Therefore, when rapid ventilation is required, the speed of the fan can be increased to speed up the air flow speed between the anode plate 201 and the cathode plate 202, thereby forming a low-pressure area between the anode plate 201 and the cathode plate 202. The anode plate 201 and the cathode plate 202 will be attracted by the low-pressure area to overcome the elastic force of the spring 803 and move closer to each other. At this time, the distance between the anode plate 201 and the cathode plate 202 acting on the air is shortened, thereby improving the effect of the anode plate 201 in adsorbing dust contained in the air.

[0040] Among them, the anode plate 201 and the cathode plate 202 use a spring 803 as an installation connection structure. Since the spring 803 has elastic potential energy, the length of the spring 803 can change with the change of air pressure, and it can reset itself through elastic force, thereby automatically adjusting the distance between the anode plate 201 and the cathode plate 202 according to the air flow speed, that is, adjusting the effective distance of the convection air.

[0041] In this embodiment, a collecting chamber 7 is further provided in the installation shell 1, and the collecting chamber 7 is located below the dust removal chamber 2 and communicated with the dust removal chamber 2;

[0042] One end of the collecting chamber 7 passes through the side wall of the mounting shell 1 , a dust box 701 is slidably arranged in the collecting chamber 7 , a pull ring and a water injection hole are arranged at one end of the dust box 701 away from the collecting chamber 7 , and the water injection hole passes through one side 701 of the dust box 701 .

[0043] The dust separated from the surface of the anode plate 201 falls downward into the dust box 701 in the collection chamber 7 due to gravity. Water is injected into the dust box through the water injection hole using a syringe or a water pipe in advance, so that the dust falls onto the water and is not easy to float.

[0044] In this embodiment, the heating chamber 4 is a tubular structure, and an extension piece 401 is disposed in the heating chamber 4 . The extension piece 401 is a spiral structure extending along the length direction of the heating chamber 4 .

[0045] The air entering the heating chamber 4 is spirally discharged along the extension piece 401, which increases the time for the air to travel from the heating chamber to the outlet, thereby increasing the time the air stays in the heating chamber, thereby fully heating the air.

[0046] In this embodiment, the extension piece 401 is an elastic piece, the end of the extension piece 401 close to the air outlet 102 is a fixed end, and the end away from the air outlet 102 is a movable end. The fixed end of the extension piece 401 is fixedly connected to the heating chamber 4.

[0047] In a natural state, the air pressure in the installation shell 1 is consistent with that in the outside because the fan 5 is not turned on to suck air into the installation shell 1. When in use, the fan 5 is turned on at the moment that the fan 5 sucks the outside air into the installation shell 1, so that the air pressure in the installation shell 1 is greater than the outside air pressure. In this state, since one end of the extension piece 401 is a movable end, the extension piece 401 is contracted, and the movable end moves toward the fixed end to adapt to the change in air pressure.

[0048] In this embodiment, the installation shell 1 is provided with two heating plates 402 , and the two heating plates 402 are respectively located at the upper and lower ends of the heating chamber 4 , and heating wires 403 are provided in the heating plates 402 .

[0049] The heating chamber 4 is cylindrical as a whole, and the two heating plates 402 are both arc-shaped. The air of the two heating plates 402 is in contact with the heating plates 402, and the heating treatment is performed through the heating wires 403 that are energized in the heating plates 402.

[0050] In this embodiment, the disinfection chamber 3 includes an upright portion and two curved portions, the two curved portions are respectively located at the two ends of the upright portion, a disinfection lamp 301 is provided at the end of the upright portion, and the irradiation direction of the disinfection lamp 301 is consistent with the length direction of the upright portion, and the two curved portions are respectively connected to the dust removal chamber 2 and the heating chamber 4.

[0051] By arranging arc-shaped portions at the upper and lower ends of the upright portion, the disinfection chamber is made to be S-shaped as a whole;

[0052] The disinfection lamp 301 is located at the end of the upright portion, and the irradiation direction is consistent with the length direction of the upright portion. After the air enters the upright portion, it is exposed to the disinfection lamp, which effectively increases the irradiation range of the disinfection lamp 301.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
