Description

Technical Field

[0001] This utility model relates to the field of indoor ventilation technology, and more specifically, to a quick-connect ventilation device for outdoor treatment facilities. Background Technology

[0002] Outdoor treatment facilities are temporary structures built in outdoor spaces for medical treatment, rehabilitation, and other related activities. These facilities are typically built to meet specific needs, such as public health emergencies, medical support for large-scale events, or to assist in the treatment of certain diseases in a natural environment. They are characterized by rapid construction, flexible layout and adjustment, and the ability to meet specific treatment needs for a certain period. Ventilation equipment can improve the air quality within outdoor treatment facilities.

[0003] A search revealed that Chinese patent CN221609636U discloses a container-type negative pressure isolation ward. The ward uses a connecting frame and a high-efficiency particulate air (HEPA) filter placed inside a fixed frame. An arc-shaped plug-in block at the bottom of the connecting frame contacts two clamping blocks. Because the clamping blocks have an arc-shaped surface, they are driven to the sides, causing them to rotate around a fixed axis. The clamping blocks also stretch a spring. As the connecting frame continues to move, the arc-shaped plug-in block is moved between the two clamping blocks. The spring tension moves the two clamping blocks back to their initial displacement, and the plug-in grooves on the inner sides of the two clamping blocks fix the arc-shaped plug-in block, allowing the connecting frame and HEPA filter to be installed.

[0004] When the above-mentioned patent is used, the air in the treatment area can be drawn out by the fan. When the wind is strong outside, the fan can be turned off and the air quality in the treatment area can be improved by natural ventilation, which can effectively save energy. However, the outside air is easily blocked by the blades on the fan and is difficult to enter the room effectively. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a quick-change ventilation device for outdoor treatment sites, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-connect ventilation device for outdoor treatment facilities, comprising a mounting frame and a duct. The bottom end of the duct passes through the mounting frame and is movably connected to it via a bearing. A fan is movably mounted at the bottom of the duct. A support plate is fixedly connected inside the mounting frame. A movable component is mounted on the support plate. The movable component includes a second stepper motor, a lead screw, a slide rod, and a movable plate. The second stepper motor is fixedly mounted inside one side of the mounting frame, and the output shaft end of the second stepper motor is fixedly connected to the lead screw. Both ends of the lead screw are movably connected to the mounting frame and the support plate via bearings. Both ends of the slide rod are fixedly connected to the mounting frame and the support plate, respectively, and both the slide rod and the lead screw pass through the movable plate. The fan is fixedly mounted at the bottom end of the movable plate, and a vertical pipe is fixedly connected to the top end of the movable plate.

[0007] Furthermore, a limiting plate is fixedly sleeved on the sliding rod, and one side of the limiting plate is in contact with the moving plate.

[0008] As can be seen, in the above technical solution, the reverse rotation of the second stepper motor can drive the fan to move directly below the air duct, and the moving plate can be limited by the limiting plate.

[0009] Furthermore, a second collar is fixedly fitted at the top edge of the outer side of the riser, and a second sealing gasket is fixedly adhered to the second collar. A first collar is fixedly fitted at the bottom edge of the outer side of the duct, and a first sealing gasket is fixedly adhered to the first collar.

[0010] It can be seen that in the above technical solution, the sealing performance between the riser and the duct can be improved by using the first collar, the first sealing gasket, the second collar, and the second sealing gasket.

[0011] Furthermore, a fixing plate is fixedly fitted at the bottom outer edge of the mounting frame.

[0012] As can be seen, in the above technical solution, the fixing plate is installed on the roof of the treatment area by bolts, thereby fixing the mounting frame to the treatment area.

[0013] Furthermore, one end of the air duct is fixedly connected to an air bucket, and a filter screen is fixedly connected inside the air bucket.

[0014] It can be seen that the above technical solutions are designed to facilitate air intake and exhaust.

[0015] Furthermore, the duct is equipped with an adjustment assembly, which includes a first stepper motor, a gear rod, and a gear ring.

[0016] Furthermore, the first stepper motor is fixedly installed inside the bottom of the mounting frame, and the output shaft end of the first stepper motor is fixedly connected to the gear rod. The gear rod is movably connected to the top of the mounting frame through a bearing, and the gear rod meshes with one side of the gear ring. The gear ring is fixedly sleeved on the air duct.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model uses a fan to generate suction to draw air from the treatment area. Indoor air enters the duct through the riser and is finally discharged through the air bucket. The second stepper motor drives the fan and riser to move horizontally and move them away from the duct. External air can enter the duct through the air bucket and finally enter the treatment area through the mounting frame. It is easy to operate and can quickly switch between natural ventilation and mechanical ventilation.

[0019] 2. This utility model uses a stepper motor to drive the gear rod to rotate, which in turn drives the gear ring and the air duct to rotate, and then drives the air duct to rotate. The position of the air duct can be adjusted according to the wind direction, so that natural wind can quickly enter the air duct. At the same time, the filter screen can filter out impurities in the natural wind. The structure is simple and easy to use. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] Refer to the instruction manual appendix Figure 1-5 This embodiment of a quick-connect ventilation device for outdoor treatment facilities includes a mounting frame 1 and a duct 2. The bottom end of the duct 2 passes through the mounting frame 1 and is movably connected to it via a bearing. A fan 7 is movably mounted at the bottom of the duct 2. A support plate 9 is fixedly connected inside the mounting frame 1. A moving component 8 is mounted on the support plate 9. The moving component 8 includes a second stepper motor 801, a lead screw 802, a slide rod 803, and a moving plate 804. The second stepper motor 801 is fixedly mounted inside one side of the mounting frame 1, and the output shaft end of the second stepper motor 801 is fixedly connected to the lead screw 802. Both ends of the lead screw 802 are movably connected to the mounting frame 1 and the support plate 9 via bearings. Both ends of the slide rod 803 are fixedly connected to the mounting frame 1 and the support plate 9, respectively. Both the slide rod 803 and the lead screw 802 pass through the moving plate 804. The fan 7 is fixedly mounted at the bottom end of the moving plate 804, and a riser 14 is fixedly connected to the top end of the moving plate 804.

[0029] Furthermore, a limiting plate 805 is fixedly sleeved on the slide rod 803, and one side of the limiting plate 805 is in contact with the moving plate 804. A second collar 12 is fixedly sleeved at the top edge of the outer side of the riser 14, and a second sealing gasket 13 is fixedly bonded to the second collar 12. A first collar 10 is fixedly sleeved at the bottom edge of the outer side of the air duct 2, and a first sealing gasket 11 is fixedly bonded to the first collar 10. A fixing plate 6 is fixedly sleeved at the bottom edge of the outer side of the mounting frame 1.

[0030] Furthermore, one end of the air duct 2 is fixedly connected to the air hopper 3, and the air hopper 3 is fixedly connected to the filter screen 4. An adjustment component 5 is provided on the air duct 2. The adjustment component 5 includes a first stepper motor 501, a gear rod 502 and a gear ring 503. The first stepper motor 501 is fixedly installed at the bottom of the inner side of the mounting frame 1, and the output shaft end of the first stepper motor 501 is fixedly connected to the gear rod 502. The gear rod 502 is movably connected to the top of the mounting frame 1 through a bearing, and the gear rod 502 meshes with one side of the gear ring 503. The gear ring 503 is fixedly sleeved on the air duct 2.

[0031] The system starts with a first-step motor 501, which drives the gear rod 502 to rotate, thereby driving the gear ring 503 and the air duct 2 to rotate, which in turn drives the air duct 3 to rotate. The position of the air duct 3 is adjusted according to the wind direction, so that natural wind can quickly enter the air duct 3. At the same time, the filter screen 4 can filter out impurities in the natural wind. The structure is simple and easy to use.

[0032] The usage method of this embodiment is as follows:

[0033] In use, the fixing plate 6 is installed on the roof of the treatment area using bolts, thus fixing the mounting frame 1 to the treatment area. The fan 7 is then activated, generating suction to draw air from the treatment area. The indoor air enters the duct 2 through the riser 14 and is finally discharged through the duct 3. It is worth noting that the riser 14 is equipped with an activated carbon plate, which purifies the indoor air. When switching to natural ventilation, the second stepper motor 801 is activated, driving the lead screw 802 to rotate. Since the lead screw 802 is threadedly connected to the moving plate 804, the sliding rod 803 restricts the rotation of the moving plate 804. Therefore, the lead screw 802 can drive the moving plate 804 to move horizontally, thereby driving the fan 7 and the riser 14 to move horizontally, and making the fan 7 and the riser 14 move away from the air duct 2. External air can enter the air duct 2 through the air hopper 3, and finally enter the treatment area through the mounting frame 1. The operation is simple and can quickly switch between natural ventilation and mechanical ventilation. Similarly, the reverse rotation of the second stepper motor 801 can drive the fan 7 to move directly below the air duct 2. The moving plate 804 can be limited by the limiting plate 805. At the same time, the sealing between the riser 14 and the air duct 2 can be improved by the first collar 10, the first sealing gasket 11, the second collar 12 and the second sealing gasket 13.
