Description

Technical Field

[0001] The utility model relates to the technical field of air purification, in particular to a mechanical filter type air purifier. Background Art

[0002] Mechanical filter air purifier is a common air purification device. Its working principle is to clean the air through mechanical filtration. This type of purifier usually includes several layers of different types of filters, each layer has different functions. "Mechanical filter type" means that the air purifier uses mechanical filtration to clean the air. This type of purifier mainly relies on physical methods, such as filters, filters, etc., to directly filter out particulate matter, dust, pollen, bacteria, etc. in the air, thereby improving air quality;

[0003] The outer side of the filter of the current mechanical filter-type air purifier is exposed to the outside. Since the outer side of the filter is directly exposed to the air, it is easy to absorb dust, dirt and other debris in the air, resulting in a thick dust layer on the surface of the filter. If the outer side of the filter is not cleaned for a long time, the accumulation of dust and dirt will hinder air circulation, reduce the filtration efficiency of the purifier, and thus affect the indoor air quality. Since the outer side of the filter is exposed to the outside, users need to clean the filter regularly to maintain its purification effect. However, since the filter is usually installed inside the purifier, the purifier needs to be opened for cleaning, which increases the difficulty and workload of cleaning. For this reason, we propose a mechanical filter-type air purifier. Utility Model Content

[0021] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified.

[0022] Embodiment:

[0023] like Figure 1-4 As shown, a mechanical filter type air purifier comprises an air purifier body 1, a base 2 is fixedly installed at the bottom end of the air purifier body 1, a filter port 3 is arranged inside the air purifier body 1, a switch 4 and a power interface 5 are arranged on the air purifier body 1, the filter port 3 comprises an inlet arranged on the left outer wall of the air purifier body 1 and an outlet arranged on the right outer wall of the air purifier body 1, a driving assembly 6 is arranged and installed at the rear end of the air purifier body 1, a cleaning assembly 7 is connected to the driving assembly 6, the driving assembly 6 comprises a second connecting rod 65 driving the cleaning assembly 7 to move, and the cleaning assembly 7 comprises a cleaning rod 77 for reciprocating and cleaning the outer wall of the filter port 3;

[0024] The driving assembly 6 includes a fixing rod 61 fixed on the rear wall of the air purifier body 1, a connecting plate 62 placed above the fixing rod 61 and fixed on the rear wall of the air purifier body 1, a rotating rod 63 rotatably connected between the fixing rod 61 and the connecting plate 62, an external thread 64 provided on the outer wall of the rotating rod 63, a second connecting rod 65 fixed on the outer wall of the top end of the rotating rod 63, and a rotating wheel 66 rotatably connected to the outer wall of the fixing rod 61;

[0025] The cleaning assembly 7 includes a movable rod 71 fixed on the outer walls of both sides of the rotating wheel 66, a first rotating arm 72 fixed on the outer end of the movable rod 71, a rotating shaft 73 arranged on the end of the first rotating arm 72, a second rotating arm 74 rotatably connected to the rotating shaft 73 at one end, a cleaning rod 77 hinged to the other end of the second rotating arm 74, a mounting frame 75 fixedly mounted on the two side walls of the air purifier body 1, and a sliding groove 76 opened in the mounting frame 75 and slidably connected to the cleaning rod 77;

[0026] When the staff needs to clean the filter opening 3, they only need to rotate the second connecting rod 65 so that the second connecting rod 65 drives the rotating rod 63 to rotate. The fixed rod 61 is set in an L shape. The left end of the fixed rod 61 is rotatably connected to the rotating wheel 66. The two ends of the rotating wheel 66 pass through the outer wall of the fixed rod 61 and are connected to the cleaning component 7. The rotating rod 63 rotates between the fixed rod 61 and the connecting plate 62 through the bearing, and the external thread 64 is synchronously driven to rotate while the external thread 64 rotates, and the rotating wheel 66 engaged therewith is driven to rotate synchronously, and the rotating wheel 66 rotates to drive The movable rods 71 ​​at both ends of the movable rod 71 rotate synchronously, and the two sets of movable rods 71 ​​drive the first rotating arm 72 fixed thereto to rotate. When the first rotating arm 72 rotates, one end of the second rotating arm 74 rotates in a circle around the axis of the first rotating arm 72, thereby pushing the other end of the second rotating arm 74 to move. The other end of the second rotating arm 74 pushes the cleaning rod 77 to slide forward in the sliding groove 76. The length of the cleaning rod 77 is set to be equal to the width of the filter opening 3. The inner wall of the cleaning rod 77 is provided with a brush to scrape and clean the filter opening 3 during the sliding process.

[0027] It is worth noting that the external thread 64 is meshed with the rotating wheel 66, and the height of the external thread 64 is set to be greater than the diameter of the rotating wheel 66. The reason for setting the height of the external thread 64 greater than the diameter of the rotating wheel 66 is to ensure that the external thread 64 can be fully meshed with the rotating wheel 66 during the rotation process, so as to effectively transmit the rotational force. Through such a design, it can be ensured that the rotational force can be stably transmitted to the rotating wheel 66 without poor meshing or disengagement, ensuring that the cleaning component 7 can clean the filter port 3 in an expected manner. Such a design can improve the reliability and stability of the mechanical filter air purifier and ensure its long-term effective operation;

[0028] The length of the first rotating arm 72 is set to be equal to half of the length of the filter opening 3. The installation frame 75 rotates the first half circle to push the cleaning rod 77 from the rear end to the front end of the filter opening 3. The installation frame 75 rotates the second half circle to pull the cleaning rod 77 from the front end to the rear end of the filter opening 3, aiming to achieve effective movement of the cleaning rod 77, so that the full length of the filter opening 3 can be completely covered for cleaning. When the installation frame 75 rotates the first half circle, since the length of the first rotating arm 72 is half of the length of the filter opening 3, the cleaning rod 77 moves from the rear end of the filter opening 3 to the rear end. The cleaning rod 77 starts to move because the rotation of the first rotating arm 72 will cause the movement of the second rotating arm 74, thereby pushing the cleaning rod 77 to slide forward in the slide groove 76, thereby cleaning the rear half of the filter opening 3. When the mounting frame 75 rotates the rear half circle, the first rotating arm 72 continues to rotate, which will cause the cleaning rod 77 to move from the front end of the filter opening 3. The purpose of this design is to ensure that the cleaning rod 77 can cover the entire length of the filter opening 3 for cleaning, so that the entire filter opening 3 can be effectively cleaned, thereby ensuring the purification effect and service life of the air purifier.
