Abstract
Description
Technical Field
[0001] This utility model relates to the field of disinfection and ventilation technology, specifically to an environmental disinfection and ventilation device. Background Technology
[0002] Disinfection can remove pathogenic microorganisms from the environment. Disinfecting medical institutions, public places, schools, and homes can reduce the risk of infectious disease transmission and improve environmental hygiene.
[0003] For example, a hospital environmental disinfection and ventilation device with announcement number "CN220567451U" involves opening the connecting plate, moving the rotating rod upwards, and then disengaging the fixing bolts from the second connecting hole by rotating them. The first and second filter plates are then replaced with the first and second brush plates. The device uses a motor to rotate the rotating rod, which in turn rotates the first and second brush plates, cleaning dust and bacteria from their surfaces. However, this device only filters and disinfects the air, failing to achieve complete disinfection. This incomplete disinfection allows unfiltered bacteria to escape, potentially affecting personnel health. Furthermore, replacing the filters requires turning multiple bolts and opening the connecting plate to move the rotating rod, which is cumbersome and time-consuming, reducing work efficiency. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of the hospital's environmental disinfection and ventilation equipment, which only filters and disinfects the air through a filter screen, and cannot achieve complete disinfection, resulting in incomplete disinfection. This makes it easy for unfiltered bacteria to be discharged, affecting the health of personnel. At the same time, the replacement of the filter screen in the hospital's environmental disinfection and ventilation equipment requires turning multiple bolts and opening the connecting plate to move the rotating rod, which is cumbersome and time-consuming, thus reducing work efficiency. Therefore, this utility model proposes an environmental disinfection and ventilation equipment.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] Design an environmental disinfection and ventilation device, including a base plate, a first outer shell fixedly connected to the upper right side of the base plate, a disinfection mechanism provided inside the first outer shell, a box body fixedly connected to the right side of the base plate, an air inlet and an air outlet fixedly connected to the left and right ends of the inner wall of the box body respectively, a dust discharge port fixedly connected to the middle inner wall of the box body, a second outer shell fixedly connected to the outer wall of the box body, a fixing mechanism provided inside the second outer shell, and a sliding groove machined on the inner wall of the box body.
[0007] Preferably, the inner wall of the chute is slidably connected to the filter screen, the upper end of the filter screen is machined with a threaded hole, and an exhaust fan is installed on the right side of the inner wall of the box.
[0008] Preferably, the disinfection mechanism includes a motor and a U-shaped tube. The output end of the motor is fixedly connected to a stirring rod, and the lower end of the stirring rod is rotatably connected to the first housing through a sealed bearing. A one-way valve is installed on the right side of the U-shaped tube.
[0009] Preferably, the two ends of the U-shaped tube are fixedly connected to the air outlet and the first outer shell, respectively, and the outer wall of the motor is fixedly connected to the first outer shell.
[0010] Preferably, the fixing mechanism includes a bent rod, the outer wall of which is engaged with a slot, the lower end of which is in contact with a spring, the other end of which is fixedly connected to a second outer shell, the outer wall of which is slidably connected to the second outer shell, a pressure plate fixedly connected to the upper end of which, and a sealing gasket provided in contact with the lower end of which is in contact with the housing.
[0011] Preferably, the lower end of the pressure plate abuts against the housing, and the slot is machined on the inner wall of the second housing.
[0012] The environmental disinfection and ventilation equipment proposed in this utility model has the following advantages: By cooperating with the disinfection mechanism and the exhaust fan, the exhaust fan is started simultaneously. The start of the exhaust fan allows outside air to enter from the air inlet, be filtered by the filter screen, and then enter the U-shaped pipe from the air outlet. It then enters the first outer shell through the one-way valve. The air enters the disinfectant solution, and the stirring rod stirs the air so that the disinfectant solution disinfects the bacteria remaining in the air. The air is then discharged from the exhaust pipe at the top, thus achieving disinfection and ventilation of the hospital environment. The disinfection mechanism further disinfects the filtered air, making the disinfection more thorough, thereby reducing the discharge of bacteria and protecting the health of personnel.
[0013] By cooperating with the fixing mechanism and the filter screen, the pressure plate is rotated in the opposite direction. The rotation of the pressure plate drives the bent rod to rotate. When the bent rod rotates out of the slot, the slot releases the vertical limit on the bent rod. Because the bent rod lacks a limit spring, it moves upward and is limited by the vertical movement of the second outer shell. The operator can directly process and remove the pressure plate. Then, the operator rotates the bolt into the threaded hole and uses the bolt to pull the filter screen vertically upward. The filter screen is then removed, and a new filter screen is inserted into the slide groove. The bent rod is then inserted into the second outer shell, the pressure plate is pressed down, and the pressure plate is rotated forward to make the bent rod enter the slot. Because the spring is compressed when pressed down, the spring rebounds and presses the bent rod against the slot. When the bent rod is inserted into the slot, the pressure plate presses tightly above the filter screen to ensure a seal. The replacement is completed without the need to rotate multiple bolts or open the connecting plate to replace the filter screen, thus saving time and improving work efficiency.

The enclosure has a valve, and a second outer shell 9 is fixedly connected to the outer wall of the housing 7. The second outer shell 9 has a fixing mechanism 8 inside. The inner wall of the housing 7 is machined with a sliding groove 10, and the inner wall of the sliding groove 10 is slidably connected to the filter screen 11. The upper end of the filter screen 11 is machined with a threaded hole 13. An exhaust fan 12 is installed on the right side of the inner wall of the housing 7. The model and working method of the filter screen 11 and the exhaust fan 12 are the same as those of the filter screen and exhaust fan in a hospital environment disinfection and ventilation equipment with announcement number "CN220567451U".
[0026] See attached document Figure 1-2 :
[0027] The disinfection mechanism 2 includes a motor 201 and a U-shaped tube 203. The output end of the motor 201 is fixedly connected to a stirring rod 202. The output shaft of the motor 201 rotates, driving the stirring rod 202 to rotate. The lower end of the stirring rod 202 is rotatably connected to the first outer shell 3 through a sealed bearing. A one-way valve 204 is installed on the right side of the U-shaped tube 203. Both the one-way valve 204 and the U-shaped tube prevent the disinfectant from flowing back into the box 7. The two ends of the U-shaped tube 203 are fixedly connected to the air outlet 4 and the first outer shell 3, respectively. The air outlet 4 delivers air to the first outer shell 3 through the U-shaped tube. The outer wall of the motor 201 is fixedly connected to the first outer shell 3. The upper end of the first outer shell 3 has an exhaust pipe.
[0028] See attached document Figure 1-4 And 7:
[0029] The fixing mechanism 8 includes a bent rod 801. The outer wall of the bent rod 801 is engaged with the slot 802. The lower end of the bent rod 801 is in contact with the spring 803. The bent rod 801 moves to compress the spring 803. The other end of the spring 803 is fixedly connected to the second outer shell 9. The outer wall of the bent rod 801 is slidably connected to the second outer shell 9. The upper end of the bent rod 801 is fixedly connected to a pressure plate 804. The movement of the pressure plate 804 drives the bent rod 801 to move. The lower end of the pressure plate 804 is in contact with the housing 7 and is provided with a sealing gasket. The sealing gasket is made of rubber and ensures airtightness. The lower end of the pressure plate 804 is pressed against the housing 7. The slot 802 is machined on the inner wall of the second outer shell 9.
[0030] Working principle:
[0031] Disinfection and ventilation equipment is used to disinfect and ventilate the hospital environment.
[0032] Preparation:
[0033] The staff poured disinfectant into the first outer casing 3 through the upper pipe (e.g.) Figure 2 (Continue until the water level is above the U-shaped tube and then slightly higher.) Then start the motor 201. The output shaft of the motor 201 rotates, driving the disinfectant solution to rotate. At the same time, start the exhaust fan 12. The exhaust fan 12 connects to the air inlet 6 through the external pipe to transport the air from the hospital environment to the inside of the housing 7. After being filtered by the filter screen 11, the air enters the U-shaped tube 203 through the air outlet 4 and then enters the first outer shell 3 through the one-way valve 204. The air enters the disinfectant solution and is then stirred by the stirring rod 202, which disinfects the bacteria remaining in the air. The air is then discharged to the outside through the upper pipe. The air from the hospital environment is drawn out and the outside air enters to achieve ventilation. After the disinfection and ventilation of the hospital environment is completed, all power is turned off.
[0034] Filter replacement process:
[0035] When filter screen 11 needs to be replaced, open the valve of ash discharge port 5 (e.g. Figure 2 The staff places the collection bucket below the filter 11 to collect the dust accumulated under it, taps the box 7 to make it vibrate and shake the floating dust on the filter 11 into the collection bucket, and then rotates the pressure plate 804 in the reverse direction (as shown in the image). Figure 1 The pressure plate 804 rotates, causing the bent rod 801 to rotate. When the bent rod 801 rotates out of the slot 802 (e.g. Figure 3 The vertical restriction of the bent rod 801 by the slot 802 is released. Because the bent rod 801 lacks the limit spring 803, it moves upward and is restricted by the second outer shell 9. The operator can directly remove the pressure plate 804, and then rotate the bolt into the threaded hole 13. Then, the operator uses the bolt to pull the filter screen 11 vertically upward and remove the filter screen 11. Then, the new filter screen 11 is inserted into the slide groove 10. Then, the bent rod 801 is inserted into the second outer shell 9 and the pressure plate 804 is pressed down. Then, the pressure plate 804 is rotated forward to make the bent rod 801 enter the slot 802. Because the spring 803 is compressed when it is pressed down, the spring 803 will rebound and press the bent rod 801 against the slot 802. When the bent rod 801 is inserted into the slot 802, the pressure plate 804 is pressed tightly above the filter screen 11 to ensure sealing. The replacement is completed.
[0036] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
