Description

Technical Field

[0001] This application relates to the field of odor removal devices, and in particular to an indoor air odor removal device. Background Technology

[0002] In daily life, indoor odors are often "invisible killers" affecting living comfort—the smell of cooking fumes in the kitchen, the damp and musty smell in the bathroom, the smell of pets, the residual formaldehyde smell after renovation, or the metabolic odors accumulated in enclosed spaces. Not only do these odors cause sensory discomfort, but long-term exposure to such environments can also affect health. A fresh air system, as an active ventilation and air exchange device, can solve the problem of indoor odors at its source, making fresh air a normal part of the home, or it can filter odors through filters and other means.

[0003] In the prior art, the fresh air device used to remove odors from indoor air has one end indoors and the other end outdoors. The outdoor end is prone to blockage due to dust, which leads to poor odor removal effect and makes it difficult to clean.

[0004] A search revealed that Chinese patent documents disclose a fresh air system (publication number: CN209622992U), but it still has the following defects:

[0005] While the aforementioned fresh air system achieves air filtration and heat exchange functions, thus realizing multi-functionality, high static pressure, large air volume, small size, high efficiency, energy saving, and environmental protection, it still has drawbacks. The outdoor end is prone to blockage due to dust, leading to poor odor removal from indoor air, and the outdoor end is difficult to clean. Utility Model Content

[0006] In order to improve the problem that the outdoor end is easily blocked by dust, resulting in poor indoor air odor removal effect, and that the outdoor end is not easy to clean, this application provides an indoor air odor removal device.

[0007] The indoor air odor removal device provided in this application adopts the following technical solution:

[0008] An indoor air odor removal device includes a fresh air system exhaust end and a fresh air system intake end installed on one side of the fresh air system exhaust end. Both the fresh air system exhaust end and the fresh air system intake end are installed at one end of the indoor air odor removal device body. The front end of the indoor air odor removal device body is connected to an air inlet, and the rear end of the indoor air odor removal device body is connected to a guide component. An abutment frame is installed inside the indoor air odor removal device body. The top of the abutment frame abuts against a placement plate. A filter component is installed through the top of the placement plate, and a partition plate is installed at the bottom of the placement plate. The filter component consists of a filter element and a centrifugal fan. Several centrifugal fans are installed through the top of the placement plate, and each centrifugal fan is covered with a filter element.

[0009] The rear ends of both the exhaust end and the intake end of the fresh air system abut against one end of the cleaning brush, and guide rods are installed at equal intervals at the rear end of the cleaning brush. One end of the guide rod is connected to one end of the connecting spring, and the other end of the connecting spring is connected to one end of the inner end of the sleeve. The sleeve is installed through the rear end of the connecting plate, and a guide rod is movably connected to one end of the sleeve.

[0010] By adopting the above technical solution and using the cleaning brush, the air intake and exhaust ends of the fresh air system can be cleaned directly indoors by controlling the cleaning brush.

[0011] Preferably, the connecting plate is symmetrically installed at one end of the connecting plate near the cleaning brush, and the connecting plate passes through the interior of the guide groove, which is opened inside both sides of the cleaning brush.

[0012] By adopting the above technical solution and using the guide groove, the cleaning brush is more stable during the process of being driven by the potential energy of the cleaning brush, and the cleaning brush has a more uniform contact effect when cleaning the air intake end and the air exhaust end of the fresh air system that are outdoors.

[0013] Preferably, the connecting plate extends through the interior of the movable cavity, and the movable cavities are all installed on one side of the outer wall of the fresh air system exhaust end and the fresh air system intake end. Guide columns are symmetrically installed inside the movable cavities, and the guide columns all extend through the interior of the through cavity. The through cavity is opened inside the top of the connecting plate.

[0014] By adopting the above technical solution, the movement of the connecting plate is guided by the guide column, thereby making the movement of the connecting plate more stable.

[0015] Preferably, one end of the connecting plate is provided with a slot, and a magnetic block is embedded inside the slot. One end of the magnetic block is magnetically attracted to one end of the card block, and the card blocks are all installed at one end of the sealing baffle.

[0016] By adopting the above technical solution, one end of the magnetic block is magnetically attracted to one end of the card block, and then the connecting plate is connected to one end of the sealing baffle by a snap-fit ​​magnetic attraction.

[0017] Preferably, the sealing baffles all abut against the front outer wall of the movable cavity, and a handle is installed between the two sealing baffles.

[0018] By adopting the above technical solution, when it is not necessary to clean the outdoor end of the fresh air system's air intake and exhaust ends with a cleaning brush, the front end of the active cavity can be sealed by a sealing baffle.

[0019] Preferably, the top of the air intake end of the fresh air system has an installation cavity, and the top of the installation cavity abuts against a sealing gasket. The sealing gasket is installed on the top of the installation frame, and a filter element is installed inside the installation frame. A handle is installed on the top of the installation frame.

[0020] By adopting the above technical solution and using the filter element, dust and other impurities in the air can be filtered during use.

[0021] Preferably, connecting sliders are installed on both sides of the mounting frame, and the connecting sliders are slidably connected inside the connecting groove. The connecting groove is symmetrically opened on the inner walls of both sides of the limiting frame, and the limiting frame is installed inside the air intake end of the fresh air system.

[0022] By adopting the above technical solution, the connecting slider and the connecting groove cooperate to guide the installation of the frame and the filter element, ensuring the stability of the frame and the filter element after installation.

[0023] Preferably, the inner sidewalls of the connecting groove are provided with first abutting protrusions at equal intervals, and the outer sidewalls of the first abutting protrusions abut against the outer sidewalls of the second abutting protrusions. The second abutting protrusions are provided with the flexible sheet at equal intervals on one side of the outer wall. The flexible sheet is installed inside the groove, and the groove is opened inside one side of the connecting slider.

[0024] By adopting the above technical solution, the outer wall of the first contacting protrusion abuts against the outer wall of the second contacting protrusion, thereby limiting the connecting slider and thus enabling the self-limiting of the mounting frame and filter element.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By utilizing the built-in cleaning brush, operation can be performed indoors without being outdoors. The cleaning brush is activated by moving the handle indoors, thus cleaning both the outdoor end of the fresh air system's intake and exhaust ends. This prevents dust accumulation and utilizes the potential energy released by the connecting spring, resulting in better cleaning and improved device performance. This enhances the device's usability and safety, and by combining the fresh air structure with traditional indoor air purification devices, it further improves the purification effect.

[0027] 2. This utility model abandons the traditional method of installing filter elements. Instead, it installs the filter element through the top of the air intake of the fresh air system and uses a self-limiting method to self-limit the installation frame and filter element after installation. This results in high stability during use and makes subsequent maintenance more convenient. Attached Figure Description

[0041] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0042] This application discloses an indoor air odor removal device.

[0043] Reference Figures 1-6 An indoor air odor removal device includes a fresh air system exhaust end 1, a fresh air system intake end 2 fixedly connected to one side of the fresh air system exhaust end 1, and fans installed inside both the fresh air system intake end 2 and the fresh air system exhaust end 1. Movable cavities 10 are fixedly connected to opposite outer walls of the fresh air system intake end 2 and the fresh air system exhaust end 1, and guide columns 11 with vertical structures are symmetrically fixedly connected inside the movable cavities 10. The guide columns 11 penetrate into corresponding through cavities 12, which are located at the top of a connecting plate 8, which penetrates the movable cavities 10. Inside, the rear end of the connecting plate 8 is fixedly connected to the front end of the connecting plate 7, and the end of the connecting plate 8 near the connecting plate 7 passes through the guide groove 9 opened at the front end of the cleaning brush 3. The cleaning brush 3 moves back and forth along the two connecting plates 8. Three guide rods 4 are fixedly connected at equal intervals at the rear end of the cleaning brush 3. The rear ends of the three guide rods 4 are all movably connected to the front end of the sleeve 6. The sleeve 6 is installed through the inside of the connecting plate 7. A connecting spring 5 is fixedly connected to one end of the sleeve 6, and one end of the connecting spring 5 is fixedly connected to one end of the corresponding guide rod 4.

[0044] During use, users can periodically move the cleaning brush 3 up and down to clean the outdoor ends of the fresh air system's air intake 2 and exhaust 1, preventing dust accumulation that could hinder the system's performance. Simultaneously, the cleaning brush 3 is powered by the potential energy released by the connecting spring 5, which drives the guide rod 4 to move, transferring this potential energy to the cleaning brush 3. This ensures better cleaning results when the cleaning brush 3 is in contact with the outdoor ends of the fresh air system's air intake 2 and exhaust 1.

[0045] Reference Figure 2 , Figure 3 and Figure 6 Each of the connecting plates 8 has a slot 13 at its front end, and a magnetic block 14 is embedded inside each slot 13. One end of the magnetic block 14 abuts against one end of the block 15, which is made of magnetic material, and is magnetically fixed. One end of the block 15 is engaged inside the slot 13, and the other end of the block 15 is fixedly connected to the rear end of the sealing baffle 16. The sealing baffles 16 abut against the front end of the movable cavity 10. A handle 17 with a concave structure is fixedly connected between the lower outer walls of the front ends of the sealing baffles 16 on both sides.

[0046] During use, when it is not necessary to clean the outdoor end of the fresh air system 2 and 1 using the cleaning brush 3, the sealing baffle 16 is engaged with the slot 13 via the clip 15 and magnetically fixed to one end of the magnetic block 14. This seals the movable cavity 10, reducing the entry of insects such as mosquitoes into the room. When it is necessary to clean the outdoor end of the fresh air system 2 and 1 using the cleaning brush 3, by grasping the handle 17 and pushing the sealing baffle 16, the cleaning brush 3 and the connecting plate 7 are moved in conjunction, thereby completing the cleaning operation.

[0047] Reference Figure 2 and Figure 7 An installation cavity is provided inside the top of the fresh air system intake end 2. A limiting frame 24 corresponding to the installation cavity is fixedly connected inside the fresh air system intake end 2. A connecting groove 23 with a "convex" structure is provided on both inner walls of the limiting frame 24. A connecting slider 22 is vertically and movably connected inside the connecting groove 23. An installation frame 19 is fixedly connected between the connecting sliders 22. A filter element 20 is fixedly connected inside the installation frame 19. A sealing gasket 18 is fixedly connected to the top of the installation frame 19. The outer wall dimension of the sealing gasket 18 is larger than the inner wall dimension of the installation cavity. A handle 21 is fixedly connected to the top of the installation frame 19.

[0048] During use, the filter element 20 can filter the air transmitted from the fresh air intake 2 to the room, reducing dust and impurities in the air and further improving the practicality of the device. At the same time, since the filter element 20 needs to be replaced regularly, this device abandons the traditional complicated replacement process. The filter element 20 can be replaced simply by vertically moving it out of the installation cavity, which improves the practicality and convenience of the device.

[0049] Reference Figure 2 and Figure 7 A groove is provided on the outer wall of the opposite end of the connecting slider 22. A flexible sheet 27 is fixedly connected inside the groove. A second abutting protrusion 26 with a semi-cylindrical structure is fixedly connected at equal intervals on one side of the outer wall of the flexible sheet 27. The outer wall of the second abutting protrusion 26 abuts against the outer wall of the first abutting protrusion 25. The first abutting protrusion 25 is fixedly connected at equal intervals to the inner wall of the connecting groove 23.

[0050] During the installation of the mounting frame 19 and the filter element 20, the connecting slider 22 is movably connected inside the mounting frame 19. The connecting slider 22 is limited by the outer wall of the second abutting protrusion 26 abutting against the outer wall of the first abutting protrusion 25, thereby limiting the mounting frame 19 and the filter element 20. This method can quickly limit the mounting frame 19 and the filter element 20, and also facilitates disassembly during later maintenance.

[0051] Reference Figure 1 , Figure 8 and Figure 9 Both the exhaust end 1 and the intake end 2 of the fresh air system are fixedly connected to one end of the indoor air odor removal device body 28. The front end of the indoor air odor removal device body 28 is connected to an air inlet 29, and the rear end of the indoor air odor removal device body 28 is connected to a guide assembly 30, which consists of a blower and a duct. A U-shaped contact frame 31 is fixedly connected inside the indoor air odor removal device body 28, and a placement plate 32 is placed on the top of the contact frame 31. Four filter components 33 are fixedly connected through the top. Each filter component 33 consists of a filter element 3301 and a centrifugal fan 3302. The filter element 3301 is threaded to the top of the placement plate 32 and covers the outside of the centrifugal fan 3302. The centrifugal fan 3302 is fixedly connected through the top of the placement plate 32. A partition plate 34 is fixedly connected to the bottom of the placement plate 32. One side of the partition plate 34 is in contact with the end of the fresh air system exhaust end 1 and the fresh air system intake end 2 inside the indoor air odor removal device body 28.

[0052] During installation, the end with the fresh air system exhaust end 1 and fresh air system inlet end 2 is attached to the wall, and the fresh air system exhaust end 1 and fresh air system inlet end 2 are installed externally. During use, the air in the current environment is drawn in through the air inlet 29 by the guide component 30, and then the air is drawn in and transported to the space below the placement plate 32 by the four filter components 33. The space below the placement plate 32 is divided into two spaces by the partition plate 34. In this way, the fresh air system exhaust end 1 will discharge the air that has been filtered and purified by the four filter components 33, and then fresh air will be drawn in to the other space through the fresh air system inlet end 2 before being discharged outside the device. This method can avoid environmental impact.

[0053] The implementation principle of the indoor air odor removal device in this application embodiment is as follows:

[0054] First, when it is not necessary to clean the outdoor end of the fresh air system intake 2 and the outdoor end of the fresh air system exhaust 1 with the cleaning brush 3, the sealing baffle 16 is snapped into the inside of the slot 13 by the clip 15 and magnetically fixed to one end of the magnetic block 14, so that the movable cavity 10 can be sealed.

[0055] Secondly, when it is necessary to clean the outdoor end of the fresh air system intake 2 and the outdoor end of the fresh air system exhaust 1 using the cleaning brush 3, by grasping the handle 17, the sealing baffle 16 is pushed to move, thereby causing the cleaning brush 3 to move up and down, and thus the cleaning brush 3 cleans the outdoor end of the fresh air system intake 2 and the outdoor end of the fresh air system exhaust 1.

[0056] Then, the air transmitted from the fresh air intake 2 to the room can be filtered through the filter element 20 to reduce dust and impurities contained in the air.

[0057] Finally, since the filter element 20 needs to be replaced regularly, this device abandons the traditional complicated replacement process. Simply move the filter element 20 vertically out of the installation cavity to replace it, and the indoor air odor removal device is thus completed.

[0058] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
