Description

Technical Field

[0001] This utility model relates to the field of deodorization and purification technology, specifically a deodorization device that facilitates filter replacement. Background Technology

[0002] Odor removal devices are suitable for both indoor and outdoor environments. Indoor pollutants and their sources mainly include radioactive gases, mold, particulate matter, renovation residues, and secondhand smoke. In recent years, increased airtightness in residences has led to the accumulation of harmful substances indoors. In areas with severe air pollution or a high prevalence of pollen allergies, opening windows for ventilation is often impractical, thus air purifiers are becoming increasingly popular.

[0003] However, in actual use, existing air purifiers accumulate a large amount of pollutants on the filter surface after a period of use, affecting the purification effect. Although the filter needs to be replaced or cleaned regularly, the design of household air purifiers is often inconvenient for users, especially cylindrical filters which are difficult to grasp, making the replacement process time-consuming and laborious. In view of this, we propose a deodorization device that facilitates filter replacement. Utility Model Content

[0004] The purpose of this invention is to provide a deodorizing device that facilitates filter replacement, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a deodorizing device that facilitates filter replacement, comprising a cylindrical body, an inner cylinder fixedly connected to the bottom surface of the inner side of the cylindrical body, and a filter element assembly disposed inside the cylindrical body, the filter element assembly comprising:

[0006] The filter element body has an upper mounting ring fixedly connected to its top, a lower mounting ring fixedly connected to its bottom, and a flexible scraper fixedly connected to its side wall.

[0007] Hinged rod one, hinged to the inner top surface of the lower mounting ring, hinged rod two is hinged to the end of hinged rod one away from the lower mounting ring, and a movable ring is hinged to the end of hinged rod two away from hinged rod one;

[0008] A magnetic ring, which is fixedly connected to the inner wall of the lower mounting ring.

[0009] Preferably, a threaded sleeve is fixedly connected to the top end face of the inner cylinder, and the threaded sleeve is threadedly connected to the cover. The cover covers the filter element assembly and guides the airflow.

[0010] Preferably, the movable ring is made of magnetic material, and the magnetic ring is magnetically connected to the movable ring to prevent the movable ring from accidentally falling off when the filter element assembly is lifted upwards.

[0011] Preferably, the flexible scraper is movably connected to the movable ring, the flexible scraper is movably connected to the inner wall of the cylinder, and the movable ring has a chamfer on the side near the flexible scraper, the chamfer being movably connected to the flexible scraper.

[0012] Preferably, the number of hinge rod one and hinge rod two is arranged in several groups, and the several groups of hinge rod one and hinge rod two are equally spaced around the top end face of the movable ring.

[0013] Preferably, a sleeve is fixedly connected to the inner top surface of the lower mounting ring, and a movable rod is fixedly connected to the top end face of the movable ring, with the sleeve and the movable rod being sleeved together.

[0014] Preferably, the top of the cylinder is provided with an air inlet and the bottom of the cylinder is provided with an air outlet. The air outlet is located at the bottom of the inner cylinder. The air extraction device provided on the inner wall of the inner cylinder draws air into the device through the top of the cylinder. Then, the air is filtered by the filter element body, enters the inner cylinder through the top of the inner cylinder, and finally exits the device from the air outlet, thereby achieving air filtration and deodorization.

[0015] Compared with the prior art, this utility model provides a deodorization device that facilitates filter replacement, and has the following beneficial effects:

[0016] 1. This deodorizing device, which facilitates filter replacement, uses a filter assembly with a movable ring that pushes a flexible scraper against the inner wall of the cylinder. The filter body is then pulled out via a handle, allowing users to easily remove the filter from the cylinder. This avoids the difficulty of grasping traditional cylindrical filters, simplifying the replacement process. The flexible scraper scrapes the inner wall of the cylinder, removing dust and impurities, reducing manual cleaning and minimizing contaminant accumulation. This ensures the purifier operates at its best after each filter replacement, maintaining efficient air purification. The movable ring and magnetic ring are magnetically connected, preventing accidental detachment when removing the filter assembly, improving stability and safety. After cleaning, the flexible scraper no longer contacts the inner wall of the cylinder, preventing unnecessary wear and extending its lifespan. It also reduces frictional resistance when inserting the filter body, allowing for easier and smoother insertion of the filter assembly.

[0017] 2. This deodorizing device, which facilitates filter replacement, provides guidance for the movable ring through the sleeve and movable rod, ensuring that the movable ring does not shift or wobble during longitudinal movement. This guarantees that the movement trajectory of the movable ring is always consistent with the central axis of the cylinder, avoiding the problem of uneven contact between the flexible scraper and the inner wall of the cylinder due to the displacement of the movable ring.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a deodorizing device that facilitates filter replacement, including a cylinder 1, an inner cylinder 2 fixedly connected to the bottom surface of the inner cylinder 1, a filter element assembly 5 disposed inside the cylinder 1, a threaded sleeve 3 fixedly connected to the top end face of the inner cylinder 2, the threaded sleeve 3 being threadedly connected to a cover 4, the cover 4 covering the filter element assembly 5 and guiding the airflow, the filter element assembly 5 including a filter element body 501, an upper mounting ring 502, a lower mounting ring 503, a flexible scraper 504, a first hinge rod 505, a movable ring 506, a magnetic ring 507, and a second hinge rod 508.

[0024] In one embodiment of this utility model, an upper mounting ring 502 is fixedly connected to the top of the filter element body 501, and a handle is provided on the top of the upper mounting ring 502. A lower mounting ring 503 is fixedly connected to the bottom of the filter element body 501. A flexible scraper 504 is fixedly connected to the side wall of the filter element body 501. An air inlet is provided at the top of the cylinder 1, and an air outlet is provided at the bottom of the cylinder 1. The air outlet is located at the bottom of the inner cylinder 2. An air extraction device provided on the inner wall of the inner cylinder 2 draws air into the device through the top of the cylinder 1. Then, the air is filtered by the filter element body 501, enters the inner cylinder 2 through the top of the inner cylinder 2, and finally exits the device from the air outlet, thereby achieving air filtration and deodorization.

[0025] Hinged rod 505 is hinged to the inner top surface of the lower mounting ring 503. A second hinged rod 508 is hinged to the end of the first hinged rod 505 away from the lower mounting ring 503. A movable ring 506 is hinged to the end of the second hinged rod 508 away from the first hinged rod 505. Several sets of first hinged rods 505 and second hinged rods 508 are arranged, and these sets of first hinged rods 505 and second hinged rods 508 are evenly spaced around the top end face of the movable ring 506. Flexible scraper 50... 4. The movable ring 506 is movably connected to the flexible scraper 504 and the inner wall of the cylinder 1. The movable ring 506 has a chamfer on the side near the flexible scraper 504 and is movably connected to the flexible scraper 504. The magnetic ring 507 is fixedly connected to the inner wall of the lower mounting ring 503. The movable ring 506 is made of magnetic material and is magnetically connected to the movable ring 506 to prevent the movable ring 506 from accidentally falling off when the filter element assembly 5 is lifted upwards.

[0026] The filter element body 501 is inserted into the cylinder 1. The movable ring 506 first contacts the bottom of the cylinder 1, and the filter element body 501 continues to move downward, causing the movable ring 506 to insert into the lower mounting ring 503. The movable ring 506 has a chamfer on the side near the flexible scraper 504, and the chamfer is movably connected to the flexible scraper 504, thereby pushing the flexible scraper 504 to abut against the inner wall of the cylinder 1. When it is necessary to disassemble the filter element body 501, rotate the cover 4 and then remove the cover 4. Pull out the filter element body 501 through the handle. The user can easily remove the filter element from the cylinder 1 through the handle, avoiding the problems associated with traditional cylindrical filters. The problem of difficult filter cartridge removal is simplified by the flexible scraper 504, which scrapes the inner wall of the cylinder 1 when the filter cartridge body 501 is removed upwards. This scrapes off the dust and impurities attached to the inner wall of the cylinder 1, reducing the trouble of manual cleaning and reducing the accumulation of pollutants in the device. This ensures that the purifier can operate in the best condition after each filter cartridge replacement, maintaining a high-efficiency air purification effect. The movable ring 506 and the magnetic ring 507 are magnetically connected to ensure that the movable ring 506 will not fall off accidentally when the filter cartridge assembly 5 is removed, thus improving the stability and safety of the device.

[0027] After cleaning the filter element body 501, shake the filter element body 501 downwards sharply, exceeding the magnetic attraction force between the magnetic ring 507 and the movable ring 506. The movable ring 506 disengages from the magnetic ring 507 and moves downwards, causing the first hinge rod 505 and the second hinge rod 508 to rotate. The outer wall of the movable ring 506 loses support for the flexible scraper 504 and thus no longer contacts the inner wall of the cylinder 1. At this time, insert the filter element body 501 into the cylinder 1. The flexible scraper 504 no longer contacts the inner wall of the cylinder 1, avoiding unnecessary wear, extending the service life of the flexible scraper 504, and reducing the frictional resistance when inserting the filter element body 501. This makes it easier and smoother to insert the filter element assembly 5 into the cylinder 1, reducing the installation difficulty.

[0028] In addition, a sleeve 6 is fixedly connected to the inner top surface of the lower mounting ring 503, and a movable rod 7 is fixedly connected to the top end face of the movable ring 506. The sleeve 6 and the movable rod 7 are sleeved together. During the longitudinal movement of the movable ring 506, the movable rod 7 and the sleeve 6 position the movable ring 506. The sleeve structure of the sleeve 6 and the movable rod 7 provides a guiding function for the movable ring 506, so that the movable ring 506 will not deviate or shake during the longitudinal movement. This ensures that the movement trajectory of the movable ring 506 is always consistent with the central axis of the cylinder 1, and avoids the problem of uneven contact between the flexible scraper 504 and the inner wall of the cylinder 1 due to the deviation of the movable ring 506.

[0029] In this invention, during use, the filter element body 501 is inserted into the cylinder 1. The movable ring 506 first contacts the bottom of the cylinder 1, and the filter element body 501 continues to move downward, causing the movable ring 506 to insert into the lower mounting ring 503. The movable ring 506 has a chamfer on the side near the flexible scraper 504, which is movably connected to the flexible scraper 504, thereby pushing the flexible scraper 504 to abut against the inner wall of the cylinder 1. When it is necessary to disassemble the filter element body 501, rotate the cover 4 and then remove the cover 4. Pull out the filter element body 501 through the handle. The user can easily remove the filter element from the cylinder 1 through the handle, avoiding the problem of traditional cylindrical filter elements being difficult to grasp, simplifying the replacement process, and saving time and effort. When the filter element body 501 is removed upward, the flexible scraper 504 scrapes the inner wall of the cylinder 1, scraping off the dust and impurities attached to the inner wall of the cylinder 1, reducing the trouble of manual cleaning. This reduces the accumulation of pollutants within the device, ensuring the purifier operates at its optimal state after each filter replacement and maintaining efficient air purification. The movable ring 506 and magnetic ring 507 are magnetically connected, ensuring that the movable ring 506 will not accidentally fall off when the filter assembly 5 is removed, thus improving the stability and safety of the device. After cleaning the filter body 501, the filter body 501 is shaken downwards sharply, exceeding the magnetic attraction between the magnetic ring 507 and the movable ring 506. The movable ring 506 detaches from the magnetic ring 507 and moves downwards, causing the first hinge rod 505 and the second hinge rod 508 to rotate. The outer wall of the movable ring 506 loses support for the flexible scraper 504, thus preventing it from contacting the inner wall of the cylinder 1. At this point, the filter body 501 is inserted into the cylinder 1, and the flexible scraper 504 no longer contacts the inner wall of the cylinder 1, avoiding unnecessary wear and extending the service life of the flexible scraper 504.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
