Description

Technical Field

[0001] The invention relates to the field of air purification, and in particular to an air purification and sterilization device for hospitals. Background Art

[0002] Hospitals need to purify the air and sterilize it at the same time to ensure the health of hospital staff and patients.

[0003] Existing air purifiers generally do not have a disinfection function. They filter the air through a filter screen and do not have a bactericidal effect, which does not meet the hospital's sterility requirements.

[0004] The existing hospital air purification and sterilization devices have the problems of large size, large space occupation, incomplete sterilization, and too high humidity of the purified air, etc. They cannot meet the requirements of emergency rooms and wards in hospitals.

[0005] Therefore, there is an urgent need for a hospital sterilization device that is small in size, can sterilize thoroughly, and has a high degree of dryness in the purified air. Summary of the invention

[0006] In order to alleviate or solve at least one aspect or at least one point of the above problems, the present invention is proposed:

[0007] According to one aspect of the present invention, the present invention provides an air purification and sterilization device for a hospital, comprising: an air intake device, an exhaust device and an air supply pipe; the air intake device comprises an upper connecting portion, and the exhaust device comprises a lower connecting portion; the air supply pipe comprises a corrugated portion; one end of the air supply pipe is connected to the air intake device, and the other end is connected to the exhaust device; the air intake device and the exhaust device can be switched between an open state and a closed state; in the open state, the upper connecting portion is separated from the lower connecting portion, and the corrugated portion is a first length L1; in the closed state, the upper connecting portion and the lower connecting portion are sealed and connected, and the corrugated portion is a second length L2; the first length L1 is greater than the second length L2.

[0008] The present invention can achieve a sufficient sterilization effect by using a gas delivery pipe to deliver the filtered gas into the disinfection and sterilization liquid. At the same time, the extensibility of the corrugated part can be used to freely switch the air intake device and the exhaust device between the open state and the closed state, making the device as a whole compact and easy to disassemble, and convenient to replace the disinfectant in the exhaust device.

[0009] In order to achieve better sterilization and disinfection effects while ensuring the compactness of the present invention, the present invention also provides the following preferred technical solutions:

[0010] Preferably, the air intake device includes an upper shell, an upper cover plate, a first bottom plate, a first filter plate and a fan, and a plurality of air inlet holes are formed on the upper shell; the first filter plate divides the air intake device into a first chamber and a second chamber; external gas enters the first chamber from the air inlet hole on one side, and enters the second chamber after being filtered by the filter plate.

[0011] Preferably, the fan is disposed in the second chamber, and the fan is connected to one end of the air supply pipe.

[0012] Preferably, the exhaust device comprises a lower shell, an inner shell, a lower cover plate, and a second bottom plate; a plurality of exhaust holes are provided on the lower shell, and the inner shell divides the exhaust device into a third chamber and a fourth chamber.

[0013] Preferably, the gas delivery pipe further comprises a coiled portion, which is arranged at the bottom of the fourth chamber and has micro pores formed on the coiled portion.

[0014] Preferably, the density of the micropores is arranged to gradually decrease from the inlet of the spiral portion to the outlet of the spiral portion.

[0015] Preferably, an exhaust pipe is also provided on the inner shell, the inlet of the exhaust pipe is connected to the upper part of the inner shell, and the lower outlet of the exhaust pipe is arranged close to the second bottom plate.

[0016] Preferably, a circulation pipe is also provided on the inner shell, the inlet of the circulation pipe is connected to the bottom of the inner shell, the outlet of the circulation pipe is connected to the upper part of the inner shell, a nozzle is provided at the outlet of the circulation pipe, and a circulation pump is provided on the circulation pipe.

[0017] Preferably, a second filter plate is provided between the inner shell and the lower shell.

[0018] Preferably, the height of the inner shell is lower than the height of the lower shell.

[0019] The present invention can fully exhaust the gas by adopting the side air intake and side exhaust modes, and at the same time, the corrugated portion can be used to conveniently switch the air intake device and the exhaust device between the open state and the closed state. The present invention also uses the spiral portion to prevent the gas from directly going out of the sterilizing liquid due to excessive gas pressure when entering the sterilizing liquid, thereby causing insufficient sterilization of the gas. The present invention further provides micropores on the spiral portion, and the density of the micropores varies with the length of the spiral portion, thereby ensuring that the gas enters the sterilizing liquid uniformly, achieving the effect of sufficient mixing and sterilization.

[0020] The present invention further sprays the sterilizing liquid in the inner shell into the fourth cavity through the nozzle through the circulation pipe, and further, after the gas from the coiled part enters the sterilizing liquid, it rises from the sterilizing liquid to the fourth cavity and further mixes with the sterilizing liquid sprayed from the nozzle, further achieving the purpose of sufficient sterilization and disinfection. Through the above arrangement, the device can achieve the purpose of sufficient sterilization while being compact in structure.

[0021] At the same time, since the gas coming out of the fourth cavity has a high humidity and contains a lot of sterilizing liquid, it is not suitable to be discharged directly into the air. The present invention further guides it downward through an exhaust pipe, and uses gravity to make the liquid settle to the bottom. The second filter plate is provided to dry and filter the gas, and the dry and sterile gas is discharged through the exhaust hole on the lower shell to meet the sterility requirements of the hospital.

Thereafter, the gas is transported to the bottom of the fourth cavity through the gas pipe 5. At this time, disinfectant is placed in the fourth cavity. The gas is ejected from the micropores 53 of the spiral part, and after being fully disinfected in the disinfectant, it rises from the disinfectant; at the same time, the pump 72 in the circulation pipe 7 is started to extract the disinfectant at the bottom and eject it from the nozzle 71; the rising gas is disinfected again. Then the gas enters the inlet of the exhaust pipe 6 and flows downward. During this period, the liquid carried by the gas will automatically flow to the bottom of the third chamber due to gravity; then, the gas rises, passes through the second filter plate 8, and is discharged through the exhaust hole 21, completing the air purification process.
