Description

Technical Field

[0001] The utility model relates to the technical field of air purifiers, in particular to a foldable and liftable caster for an air purifier. Background Art

[0002] Air purifier, also known as "air cleaner", air freshener, or purifier, refers to a household appliance that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, decoration pollution such as formaldehyde, bacteria, allergens, etc.), and effectively improve the cleanliness of the air. It is mainly divided into household, commercial, industrial, and building types. There are many different technologies and media in air purifiers, enabling it to provide users with clean and safe air.

[0003] An existing patent (Announcement No.: CN108954552A) discloses an air purifier that uses a retractable air intake mechanism to automatically hide the air intake cover when the compressed air purification device is not in use, preventing insects from entering and contaminating the air purifier. The negative pressure generated by the air compression mechanism compresses the air and forms a high-speed airflow, which is then filtered and purified through the air purification pipe and air purification mechanism in turn, thereby intercepting particulates in the air. In the process of implementing this solution, the following problems were found in the existing technology and have not been well solved:

[0004] During use, the pulley at the bottom of the device is directly fixed to the bottom of the purifier. However, in actual use, it is often necessary to adjust the height of the purifier to ensure the purification effect. In addition, during transportation or long-term storage, the pulley is prone to collision with other objects, causing unnecessary damage. Utility Model Content

[0031] The following is combined with Figure 1-5 The utility model is described in further detail.

[0032] Please refer to the attached figure in the instruction manual Figure 1-5 The utility model provides an embodiment of a foldable and liftable caster for an air purifier, comprising a purifier body 1 and a mounting block 7. A bottom plate 2 is connected to the bottom of the purifier body 1, and insertion rods 10 are connected to both sides of the bottom plate 2. The extension block 9 inside the bottom plate 2 is fixed by the insertion rods 10 to complete the height adjustment work. An adsorption magnet 11 is connected to the outside of the insertion rod 10. The adsorption magnet 11 is used to ensure that the insertion rod 10 does not shake during use. The extension block 9 is also connected to the inside of the insertion rod 10. The extension block 9 is located above the linkage block 3. A second spring 12 is connected above the linkage block 3. The second spring 12 is used to pull the linkage block 3 upward, and the linkage block 3 is stored when not in use.

[0033] Adjustment blocks 13 are connected to both sides of the mounting block 7, and the outer side of the adjustment block 13 is connected to an anti-slip block 14. The adjustment block 13 ensures that the mounting block 7 is stable and can be used normally. A connecting rod 6 is connected to the top of the mounting block 7, and a first spring 5 is connected to the top of the connecting rod 6. The connecting rod 6 is pulled back to its original position by the first spring 5 to complete the storage work. The outer side of the connecting rod 6 is connected to the storage block 4.

[0034] See the attached drawings in the specification Figure 1-5 The connection between the bottom plate 2 and the purifier body 1 is a hot-melt connection. Insertion grooves are symmetrically distributed on both sides of the bottom plate 2. The connection between the bottom plate 2 and the insertion rod 10 is a sliding connection. The extension block 9 on the inner side of the bottom plate 2 is fixed and adjusted by the insertion rod 10 to ensure subsequent use.

[0035] See the attached drawings in the specification Figure 1-5 A second spring 12 is evenly and equidistantly distributed above the linkage block 3. The linkage block 3 is connected to the extension block 9 by hot melt connection, and the extension block 9 is connected to the base plate 2 by sliding connection. The extension block 9 is connected to the insertion rod 10 to ensure smooth adjustment.

[0036] See the attached drawings in the specification Figure 1-5 The connection between the connecting rod 6 and the storage block 4 is a sliding connection. The connecting rod 6 forms a spring return structure with the purifier body 1 through the first spring 5. The storage block 4 and the purifier body 1 are installed in an integrated manner. The connecting rod 6 cooperates with the storage block 4 to facilitate the height adjustment of the mounting block 7, and the first spring 5 is used to ensure the stability of the connecting rod 6.

[0037] See the attached drawings in the specification Figure 1-5The connection between the mounting block 7 and the pulley body 8 is a rotating connection, the mounting block 7 and the connecting rod 6 are installed in an integrated manner, and the connection between the mounting block 7 and the linkage block 3 is a sliding connection. The pulley body 8 is limited by the mounting block 7, and the pulley body 8 is also folded when the mounting block 7 is stored.

[0038] See the attached drawings in the specification Figure 1-5 The connection between the insertion rod 10 and the extension block 9 is a sliding connection. The insertion rod 10 and the adsorption magnet 11 are installed in an integrated manner. The adsorption magnet 11 and the base plate 2 are adsorbed with each other. The adsorption magnet 11 is used to ensure that the insertion rod 10 will not fall loose during use, ensuring that the height adjustment work is carried out smoothly.

[0039] See the attached drawings in the specification Figure 1-5 The adjusting blocks 13 are symmetrically distributed on both sides of the mounting block 7. Anti-slip blocks 14 are symmetrically distributed on both sides of the adjusting block 13. The anti-slip blocks 14 and the edges of the mounting block 7 form a magnetic adsorption structure. The anti-slip blocks 14 are used to stabilize the mounting block 7 during use and prevent the mounting block 7 from being automatically retracted into the interior.

[0040] Working principle: When in use, first, when the height needs to be adjusted, place the purifier body 1 on its side, then pull the linkage block 3 to move the linkage block 3 toward the outside, and at the same time, the linkage block 3 drives the extension block 9 to move toward the outside. When it moves to the appropriate height, insert the rod 10 through the bottom plate 2 and the extension block 9 to complete the fixation until the adsorption magnet 11 fits the inside of the bottom plate 2 to ensure the stability of the insertion rod 10, and finally straighten the purifier body 1;

[0041] As mentioned above, when the purifier body 1 needs to be transported or stored, the insertion rod 10 is pulled out, so that the second spring 12 pulls the linkage block 3 to fit the bottom of the base plate 2, and at the same time presses the adjustment block 13 inward so that the adjustment block 13 enters the interior of the mounting block 7. At this time, the limit of the mounting block 7 is released, and the first spring 5 pulls the connecting rod 6 to reset, so that the mounting block 7 is retracted into the interior of the linkage block 3, driving the pulley body 8 to enter the interior of the linkage block 3.

[0042] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
