Description

Technical Field

[0001] The utility model relates to the technical field of indoor waste gas treatment, in particular to a ventilation device for indoor waste gas treatment. Background Art

[0002] "Indoor" is a term describing a spatial location, referring to spaces or rooms within a building. Indoor exhaust gas primarily refers to gases generated within a building that are harmful to human health or the environment. These exhaust gases originate from a variety of sources, including but not limited to interior decoration materials, furniture, household appliances, cooking processes, and coal-fired heating. Exhaust gas contains harmful substances such as formaldehyde, benzene, volatile organic compounds, particulate matter, sulfur dioxide, and nitrogen oxides. These substances, when retained indoors for extended periods, can adversely affect human health. Ventilation equipment is required to treat indoor exhaust gas.

[0003] Common ventilation equipment for indoor exhaust gas treatment typically consists of a motor, impeller, fan housing, shroud, bracket, and control system. The control system uses the motor to rotate the impeller, extracting exhaust gas from the room and discharging it outdoors. The shroud surrounds the impeller, directing incoming airflow onto it. The fan housing supports and protects the impeller and shroud. The bracket is the mounting bracket for the ventilation equipment, securing the fan housing, motor, and other components.

[0004] Traditional ventilation equipment for treating indoor exhaust gas, because indoor exhaust gas contains particulate impurities of different particle sizes, when the exhaust gas passes through the ventilation equipment, the impurities cause wear on the internal components of the ventilation equipment, such as impellers, bearings, etc., and the wear and tear will shorten the service life of the equipment and increase the cost of maintenance and replacement. In order to solve the above problems, some ventilation equipment for treating indoor exhaust gas, by adding a filter component, such as a filter screen, at the air inlet end of the ventilation equipment, so that the indoor exhaust gas needs to pass through the filter component to enter the ventilation equipment and be discharged to the outside. However, in this way, during use, the impurities in the exhaust gas will be adsorbed on the surface of the filter component, which will not only cause the air flow rate to be too slow or even blockage, but also when the filter component is replaced, the equipment needs to be stopped for a long time, thereby delaying the treatment of the indoor exhaust gas. For this reason, a ventilation equipment for treating indoor exhaust gas is proposed. Utility Model Content

[0016] Preferably, a return spring is sleeved on the center of the surface of the positioning rod, and a connecting plate is mounted on the lower portion of the surface of the positioning rod and engages with the return spring. Connecting rods are mounted on the upper and lower portions of the inner side of the fixing plate and connected to the connecting cylinder. The return spring drives the positioning rod to move on the fixing plate via the connecting plate and is inserted into the positioning groove, which not only ensures the stability of the connection between the connecting cylinder and the filter plate, but also facilitates assembly and disassembly operations.

[0017] (3) Beneficial effects

[0018] Compared with the prior art, the present invention provides a ventilation device for indoor exhaust gas treatment, which has the following beneficial effects:

[0019] This ventilation device for treating indoor exhaust gas places a filter plate in a set of connecting tubes, then rotates the connecting tubes to connect them to the duct.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] The utility model provides a technical solution, a ventilation device for indoor waste gas treatment, including: Figure 1 , a device housing 1, and a conduit 2 provided at the air inlet end of the device housing 1, and a drive motor 6 is installed at the center of the top front end of the device housing 1, and a rotating shaft 4 is coaxially connected to the front end of the drive motor 6;

[0027] See also Figure 2 The rotating frame 3 is arranged at the front end of the rotating shaft 4 and is coaxially connected. The center of the surface of the rotating shaft 4 is rotatably connected to the fixed frame 5, which is connected to the device housing 1. The top and bottom of the rotating frame 3 are connected to the connecting ring 7;

[0028] See also Figure 3 The connecting tube 8 is arranged in the inner cavity of the connecting ring 7, and the connecting tube 8 and the connecting ring 7 are tightly fitted. A filter plate 9 is installed in the inner cavity of the connecting tube 8, and the connecting tube 8 corresponds to the conduit 2. After the filter plate 9 is placed in one set of connecting tubes 8, the connecting tube 8 is rotated to connect with the conduit 2. When replacement is required, the new filter plate 9 is installed in the other set of connecting tubes 8. The driving motor 6 drives the rotating frame 3 to rotate through the rotating shaft 4, and the rotating frame 3 drives the two sets of connecting tubes 8 to rotate and adjust their positions through the connecting ring 7, so that the used filter plate 9 in the connecting tube 8 can be replaced. In this way, not only can the filter plate 9 be replaced in a timely manner to avoid the occurrence of slow air flow or even blockage, but also when replacing, there is no need to stop the equipment housing 1 for a long time, which will not affect the treatment of indoor exhaust gas.

[0029] See also Figure 3 , the filter plate 9 is vertically installed with a limit plate 10 at the center position on both sides, and the limit plate 10 is designed as a whole in an arc shape, and a positioning groove 11 is opened at the front and rear ends of the outer side of the limit plate 10. The filter plate 9 is connected and installed through the limit plate 10 and the positioning groove 11.

[0030] See also Figure 2 The inner wall of the connecting tube 8 is provided with limiting grooves 12 on both sides. The limiting grooves 12 are designed as a whole in an arc shape and correspond to the position, size and shape of the limiting plate 10. When the filter plate 9 is installed in the interior of the connecting tube 8, the limiting plate 10 is inserted into the limiting groove 12 for connection.

[0031] See also Figure 4 A fixing plate 13 is installed at the center of the front and rear ends of the outer side of the connecting tube 8, and a positioning rod 14 is inserted and connected at the center of the fixing plate 13. The inner end of the positioning rod 14 extends inward through the outer wall of the connecting tube 8 and corresponds to the positioning groove 11. The positioning rod 14 passes through the fixing plate 13 and the connecting tube 8 and is connected to the positioning groove 11. Side grooves 15 are opened on both sides of the center of the fixing plate 13, and side protrusions 16 are added to the upper surface of the positioning rod 14, which correspond in size and shape to the side grooves 15. When the positioning rod 14 rotates after passing through the fixing plate 13, the side protrusions 16 are misaligned with the side grooves 15, ensuring the stability of the connection between the fixing plate 13 and the positioning rod 14. A return spring 17 is sleeved at the center of the surface of the positioning rod 14, and a connecting plate 18 is installed at the lower surface of the positioning rod 14 and fits with the return spring 17. Connecting rods 19 are installed on the upper and lower inner side surfaces of the fixing plate 13 and are connected to the connecting tube 8. The return spring 17 drives the positioning rod 14 to move on the fixed plate 13 through the connecting plate 18 and is inserted into the positioning groove 11, which not only ensures the stability of the connection between the connecting cylinder 8 and the filter plate 9, but also facilitates the disassembly and assembly operations.

[0032] This solution involves first placing the filter plate 9 within one set of connecting tubes 8, then rotating the connecting tubes 8 to connect them to the conduit 2. When a replacement filter plate 9 is needed, a new filter plate 9 is installed within the other set of connecting tubes 8. The drive motor 6 then rotates the rotating frame 3 via the rotating shaft 4, and the rotating frame 3 then rotates and adjusts the position of the two sets of connecting tubes 8 via the connecting ring 7, allowing the used filter plate 9 within the connecting tube 8 to be replaced. After the filter plate 9 is installed within the connecting tube 8, the limit plate 10 is inserted into the limit groove 12 to connect them. The return spring 17 drives the positioning rod 14 to move on the fixed plate 13 via the connecting plate 18 and insert it into the positioning groove 11. After the positioning rod 14 passes through the fixed plate 13, it rotates, causing the side protrusion 16 to be misaligned with the side groove 15.
