Description

TECHNICAL FIELD

[0001] The utility model relates to the field of purifier, especially a smoke purifier. BACKGROUND

[0002] The smoke purifier is a device for purifying harmful smoke and particulate matters in the air, which is widely used and can effectively improve air quality and protect people's health. Smoke contains impurity particles of different sizes, from tiny nano-level particles to larger micron-level particles. The shapes of these particles are also different, such as spherical, flaky, and fibrous. These impurity particles are harmful to human health and the environment. They can deposit in the respiratory tract and lungs.

[0003] Hospitals are places that need to pay close attention to air quality because air pollutants can adversely affect patient treatment and recovery. The smoke purifier can remove smoke particles and other harmful substances in the air, thereby improving air quality and providing a healthier environment for patients and medical staff. The existing smoke purifier generally filters impurities in smoke before purifying smoke. When filtering impurities in smoke, the filter screen is used for filtering. Since the existing filter screen is generally set vertically to the direction of gas flow, the impurities in the gas are easily adhered to the mesh holes of the filter screen, which is not convenient to clean and to some extent affects the filtering effect of the filter screen.

[0004] Therefore, it is necessary to provide a new smoke purifier to solve the above technical problems. SUMMARY

[0005] To solve the above technical problems, the utility model provides a smoke purifier.

[0006] The smoke purification device provided by this utility model includes an outer casing and a rotating device. A first inner casing and a second inner casing are installed inside the outer casing via an elastic device. The inner cavity of the first inner casing is connected to the outer side of the outer casing via an air supply device. Multiple first filters are installed inside the first inner casing, all inclined towards the connection between the first inner casing and the air supply device. The aperture of the multiple first filters gradually decreases along the direction away from the air supply device. The second inner casing is connected to the end of the first inner casing away from the air supply device via a first bellows pipe. A through hole is opened at the end of the second inner casing away from the first bellows pipe for connecting to the inner cavity of the outer casing. Multiple second filters are installed inside the second inner casing, all inclined towards the connection between the second filter and the first bellows pipe. The aperture of the multiple second filters gradually decreases along the direction away from the first bellows pipe, with the aperture of the second filter closer to the first bellows pipe being smaller than the aperture of the first filter away from the air supply device. The rotating device is installed between the first inner casing and the second inner casing, and can drive the first inner casing and the second inner casing to move vertically.

The multiple second filters 5 are all inclined towards the connection between the second filter 5 and the first bellows pipe 6. The aperture of the multiple second filters 5 gradually decreases along the direction away from the first bellows pipe 6. The aperture of the second filter 5 closer to the first bellows pipe 6 is smaller than the aperture of the first filter 4 away from the air supply device. A rotating device is installed between the first inner box 2 and the second inner box 3. The rotating device can drive the first inner box 2 and the second inner box 3 to move vertically.

[0023] It should be noted that the outer box 1, the first inner box 2 and the second inner box 3 in this device can all be understood as a shell structure with a sealed door. When cleaning the impurities in the first inner box 2 and the second inner box 3, the sealed doors of the first inner box 2 and the second inner box 3 can be opened for cleaning.

[0024] The air supply device includes a ventilation pipe 7, a second bellows pipe 8, and a fan 9. One end of the ventilation pipe 7 is installed on the outer casing 1, and the fan 9 is installed inside the outer casing 1. The input end of the fan 9 is connected to the ventilation pipe 7, and the output end of the fan 9 is fixedly connected to one end of the second bellows pipe 8. The other end of the second bellows pipe 8 is connected to the inner cavity of the first inner casing 2. The fan 9 draws the gas from the ventilation pipe 7 to the second bellows pipe 8. After the gas enters the first inner casing 2, it passes through multiple first filters 4 in sequence and then enters the second inner casing 3 from the first bellows pipe 6. After passing through multiple second filters 5 in sequence, the impurities are filtered through the first filters 4 and the second filters 5.

[0025] The elastic device includes two first side plates 10, two second side plates 11, and four elastic elements. The two first side plates 10 are respectively installed on both sides of the first inner box 2, and the two second side plates 11 are respectively installed on both sides of the second inner box 3. The four elastic elements are all installed on the inner wall of the outer box 1. The elastic elements pass through the first side plates 10 and the second side plates 11. The elastic elements include a rod 13, a first spring 14, a second spring 22, and two upright plates 12. The two upright plates 12 are fixedly installed on the inner wall of the outer box 1. The rod 13 is fixedly installed between the two upright plates 12 and passes through the first side plates 10 and the second side plates 11. The first spring 14 is sleeved on the rod 13. The two ends of the first spring 14 are respectively fixedly connected to the upright plate 12 and the first side plate 10. The second spring 22 is sleeved on the rod 13. The two ends of the second spring 22 are respectively fixedly connected to the upright plate 12 and the second side plate 11.

[0026] The rotating device includes a rotating rod 15 and an eccentric wheel 16. The rotating rod 15 is rotatably connected to the outer box 1, and one end of the rotating rod 15 extends to the outside of the outer box 1 and is fixedly mounted with a handle 17. The eccentric wheel 16 is fixedly sleeved on the rotating rod 15. When the handle 17 is rotated, the handle 17 drives the rotating rod 15 and the eccentric wheel 16 on it to rotate. The eccentric wheel 16 continuously impacts the first inner box 2 and the second inner box 3. The first spring 14 and the second spring 22 continuously deform, realizing the reciprocating motion of the first inner box 2 and the second inner box 3 in the vertical direction, which facilitates the cleaning of impurities.

[0027] Multiple activated carbon plates 18 are installed inside the outer casing 1. The multiple activated carbon plates 18 are arranged in an alternating manner. All of the multiple activated carbon plates 18 are fixedly connected to one side of the inner wall of the outer casing 1. A HEPA filter layer 19 and a cold catalyst filter layer 20 are installed at the bottom of the outer casing 1.

[0028] The working principle of this utility model is as follows: When using the device, the fan 9 draws gas from the ventilation pipe 7 to the second bellows pipe 8. After entering the first inner box 2, the gas passes through multiple first filters 4 in sequence, and then enters the second inner box 3 from the first bellows pipe 6. After passing through multiple second filters 5 in sequence, the gas moves along multiple staggered activated carbon plates 18. The activated carbon plates 18 purify the smoke through adsorption. The gas passing through the activated carbon plates 18 passes through the HEPA filter layer 19 and the cold catalyst filter layer 20, and finally exits from the exhaust port 2 at the bottom of the outer box 1. The device discharges from one point. When cleaning the first filter screen 4 and the second filter screen 5, the handle 17 can be rotated. The handle 17 drives the rotating rod 15 and the eccentric wheel 16 on it to rotate. The eccentric wheel 16 continuously impacts the first inner box 2 and the second inner box 3. The first spring 14 and the second spring 22 continuously deform, realizing the reciprocating motion of the first inner box 2 and the second inner box 3 in the vertical direction, which facilitates the cleaning of impurities. In addition, the first filter screen 4 and the second filter screen 5 are both set to be inclined in this device. During the movement of the first filter screen 4 and the second filter screen 5, impurities are easily dropped due to gravity.
