Description

Technical Field

[0001] This invention relates to the field of airborne bacteria sterilization and purification technology, and in particular to a bacteria inactivation device. Background Technology

[0002] Bacteria are pathogens of many diseases in most cases, but they are also divided into beneficial bacteria and harmful bacteria. Harmful bacteria can enter the human body through contact, respiratory tract and digestive tract, causing discomfort. However, there are also beneficial bacteria, which can be used to assist in fermentation, the production of some antibiotics and wastewater treatment.

[0003] Harmful bacteria, being harmful to humans, require sterilization in certain environments to ensure safety. This process typically involves using ultraviolet light, chemical spraying, or chemical fumigation. Sterilization usually takes 30 to 90 minutes, and personnel must stay as far away from the work area as possible to prevent injury. After sterilization, the environment must be fully ventilated before entry is permitted. The overall sterilization process is time-consuming, and residual chemical odors can negatively impact personnel.

[0004] content

[0005] The purpose of this invention is to solve the following problems existing in the prior art:

[0006] Harmful bacteria, being harmful to humans, require sterilization in certain environments to ensure safety. This process typically involves methods such as ultraviolet light, chemical spraying, or chemical fumigation. Sterilization usually takes 30 to 90 minutes, and personnel must stay as far away from the work area as possible to prevent injury. After sterilization, the environment must be fully ventilated before re-entry. The overall sterilization process is time-consuming, and residual chemical odors can negatively impact personnel.

[0007] To address the problems existing in the prior art, the invention provides a bacterial inactivation device, including a device housing and an air pump installed inside the device housing. The air pump input end is provided with a connecting pipe, and a sterilization component is inserted into the top of the connecting pipe. The air pump output end is connected to a heating component through an air pipe. The output end of the heating component is connected to a connecting rectangular tube, and a filter device is installed at the other end of the connecting rectangular tube. An air inlet channel and an air outlet channel are respectively provided at the top and bottom of the housing. A diffuser nozzle is provided on the side of the filter device near the air outlet channel.

[0008] The sterilization components include a liquid tank and a mounting plate installed on top of the liquid tank;

[0009] The heating components include a heating chamber and a partition installed inside the heating chamber;

[0010] The filtration device includes a filter box and filter media installed inside the filter box.

[0011] The invention provides a bacterial inactivation device.

[0012] Furthermore, an air inlet pipe is inserted inside the mounting plate, a movable plug is inserted at the bottom of the air inlet pipe, a rubber membrane is provided at the bottom of the movable plug, a limiting seat is sleeved at the bottom of the movable plug, a spring is provided between the movable plug and the limiting seat, a connecting hole is provided at the bottom of the limiting seat, and a vent hole is provided on the surface of the movable plug located inside the air inlet pipe.

[0013] The intake pipe has an air distribution plate installed at one end near the moving plug, and radial grooves and annular grooves are provided on the bottom side of the bottom near the moving plug, and the annular grooves and radial grooves are interconnected.

[0014] There are two sets of vents, and the two sets of vents are arranged in a double ring on the top surface of the moving plug. The top set of vents has a vertical grid inside, and the bottom set of vents has a diamond grid on its surface.

[0015] Furthermore, the surface of the partition is provided with heating wires, which are arranged in an S-shape on the surface of the partition, and the partitions are arranged in an interlaced manner inside the heating chamber.

[0016] Furthermore, the filter material is divided into ceramic filter plates and activated carbon plates, and a set of activated carbon plates is provided between every two ceramic filter plates. Each set of activated carbon plates consists of three activated carbon sheets.

[0017] Furthermore, there are at least four sterilization components, and connecting pipes are provided between the four sterilization components to connect them to each other.

[0019] Furthermore, the connecting rectangular tube is S-shaped and is positioned between the heating component and the filter device.

[0020] Furthermore, a control device is installed on the surface of the housing, and the control device is connected to the heating component and the air pump respectively.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] This invention utilizes a pump to generate suction, creating negative pressure within the liquid tank via a connecting pipe. Under this negative pressure, outside air is drawn into the tank through the inlet pipe. Since the outlet of the inlet pipe is located near the bottom of the tank, the air discharged directly contacts the sterilizing liquid. Furthermore, the air distribution plate forms fine bubbles, slowing its upward movement and increasing the contact area with the sterilizing liquid. The sterilized air is then pumped to a heating element to dry it and further kill bacteria. The air then passes through a connecting tube into a filter element, where the odor from the sterilizing liquid is absorbed and the temperature decreases before being discharged. The entire system allows operators to approach the sterilization process, and the environment is safe to enter after sterilization without any odor. This shortens the sterilization time while purifying the air. Attached Figure Description

Detailed Implementation

[0032] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0033] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0034] Example 1

[0035] like Figure 1-6 As shown, this embodiment proposes a bacterial inactivation device, which includes a device housing 1 and an air pump 2 installed inside the device housing 1. The air pump 2 is provided with a connecting pipe 3 at its input end, and a sterilization component 4 is inserted into the top of the connecting pipe 3. There are at least four sterilization components 4, and a connecting pipe is provided between the four sterilization components 4 to connect the four sterilization components 4 to each other. A heating component 5 is installed at the output end of the air pump 2 through an air pipe. A connecting rectangular tube 6 is installed at the output end of the heating component 5, and a filter device 7 is installed at the other end of the connecting rectangular tube 6. An air inlet channel 8 and an air outlet channel 9 are respectively provided at the top and bottom of the housing 1. A diffuser 10 is provided on the side of the filter device 7 near the air outlet channel 9.

[0036] The sterilization component 4 includes a liquid tank 401 and a mounting plate 402 mounted on top of the liquid tank 401. Connecting pipes 3 are C-shaped pipes with openings at both ends extending into the liquid tank 401 and close to the bottom of the mounting plate 402. Each connecting pipe 3 is interconnected and connected to the input end of the air pump 2 via a pipeline. An air inlet pipe 403 is inserted inside the mounting plate 402, and a movable plug 404 is inserted at the bottom of the air inlet pipe 403. An air distribution plate 410 is mounted at the bottom of the air inlet pipe 403 near the movable plug 404, and radial and annular grooves are provided on the bottom side of the bottom of the air inlet pipe 403 near the movable plug 404. The groove and the radial groove are interconnected. A rubber membrane 405 is provided at the bottom of the movable plug 404. A limiting seat 406 is sleeved at the bottom of the movable plug 404. A spring 407 is provided between the movable plug 404 and the limiting seat 406. A connecting hole 408 is provided at the bottom of the limiting seat 406. A vent hole 409 is provided on the part of the movable plug 404 located inside the air intake pipe 403. There are two sets of vent holes 409, and the two sets of vent holes 409 are arranged in a double ring on the top surface of the movable plug 404. A vertical grid is provided inside the top set of vent holes 409, and a diamond grid is provided on the surface of the bottom set of vent holes 409.

[0037] The heating component 5 includes a heating chamber 501 and a partition 502 installed inside the heating chamber 501;

[0038] The filtration device 7 includes a filter box 701 and filter media 702 installed inside the filter box 701.

[0039] Specifically, this embodiment proposes a bacterial inactivation device. This device utilizes a control device 11 to control the input of a commercially available air pump 2 to generate suction. Through a connecting pipe 3, a negative pressure is created within the liquid tank 401. Under this negative pressure, outside air enters the air inlet pipe 403. After entering the air inlet pipe 403, the air flows along the diamond-shaped grid of the vent holes 409 on the surface of the movable plug 404 and is discharged into the liquid tank 401. During discharge, fine bubbles are formed and come into contact with the sterilization liquid within the liquid tank 401. Furthermore, when the power of the air pump 2 increases, the negative pressure within the liquid tank 401 intensifies. Pulling the movable plug 404 downward through the connecting hole 408 causes the rubber membrane 405 at the bottom of the movable plug 404 to deform. When the rubber membrane 405 can no longer deform, the movable plug 404 is pulled downward and the spring 407 is compressed, ensuring that the movable plug 404 will only move downward when the negative pressure is sufficient. When the movable plug 404 moves downward, the vent hole 409 with a vertical grid at the top leaves the bottom of the air inlet pipe 403. The vertical grid is exposed inside the liquid pool 401, and the air in the air inlet pipe 403 can be discharged outward along the vertical grid of the vent hole 409, which improves sterilization efficiency.

[0040] Example 2

[0041] like Figure 1-8 As shown, this embodiment proposes a bacterial inactivation device, which includes a device housing 1 and an air pump 2 installed inside the device housing 1. The air pump 2 is provided with a connecting pipe 3 at its input end, and a sterilization component 4 is inserted into the top of the connecting pipe 3. The air pump 2 is provided with a heating component 5 installed through an air pipe at its output end. The heating component 5 is provided with a connecting rectangular tube 6 at its output end, and a filter device 7 is provided at the other end of the connecting rectangular tube 6. The top and bottom of the housing 1 are respectively provided with an air inlet channel 8 and an air outlet channel 9. The filter device 7 is provided with a diffuser nozzle 10 on the side near the air outlet channel 9.

[0042] The sterilization component 4 includes a liquid tank 401 and a mounting plate 402 disposed on top of the liquid tank 401.

[0043] The heating component 5 includes a heating box 501 and a partition 502 installed inside the heating box 501. Heating wires 503 are provided on the surface of the partition 502. The heating wires 503 are arranged in an S-shape on the surface of the partition 502, and the partitions 502 are arranged in an interlaced manner inside the heating box 501.

[0044] The filtration device 7 includes a filter box 701 and a filter material 702 installed inside the filter box 701. The filter material 702 is divided into ceramic filter plates and activated carbon plates, and a set of activated carbon plates is provided between every two ceramic filter plates. Each set of activated carbon plates consists of three activated carbon sheets.

[0045] Specifically, in this embodiment, a bacterial inactivation device is proposed. After performing Example 1, air enters the heating chamber 501 and first contacts the partition 502. Upon encountering resistance, the air changes direction and continues to move. During this movement, the air contacts the next partition 502 and changes direction again. This process is repeated multiple times before the air enters the connecting rectangular tube 6. While inside the heating chamber 501, the air is in contact with the partition 502 and is also in contact with the heating wire 503 on the surface of the partition 502. The heating wire 503 is heated by the control device 11, which dries and heats the air. The air entering the connecting rectangular tube 6 enters the filter box 701 through the connecting rectangular tube 6. It passes through several layers of filter material 702 composed of ceramic filter plates and activated carbon plates, and gradually cools down during the process. Odors and impurities in the air are adsorbed by the filter material 702. Finally, when the air passes through the diffuser 10, the airflow speed slows down due to the increased diameter of the diffuser 10, and the air is discharged to the external environment through the outlet channel 9.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
