Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to an air purifier. Background Art

[0002] In the existing purifier design, circular machines mostly use cylindrical filters and open air inlets on the machine casing, which affects the appearance of the purifier. After the purifier has been used for a period of time, the air inlet and filter of the purifier are covered with dust, which seriously affects the overall appearance and is difficult to clean.

[0003] If bottom air inlet is used, the distance between the filter and the shell becomes smaller and the air inlet is restricted. In order to meet the air inlet requirements, the outer diameter of the filter is often designed to be reduced, which results in a significant reduction in the performance of the purifier. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide an air purifier which can beautify the appearance of the purifier, be easy to clean, and maintain the performance of the purifier.

[0005] In order to solve the above technical problems, the utility model provides an air purifier, comprising a housing, a filter installed inside the housing, and an air inlet cover, wherein the air inlet cover is installed at the bottom of the air purifier;

[0006] The filter includes an upper frame cover, a lower frame cover, and a filter element connected between the upper frame cover and the lower frame cover. The diameter of the lower frame cover is smaller than that of the upper frame cover, and the lower perimeter of the filter element is smaller than the upper perimeter, so that the filter is enclosed into a conical filter.

[0007] In some embodiments, an annular groove with a width of H is provided on opposite sides of the upper frame cover and the lower frame cover, and the upper and lower ends of the filter element are respectively installed in the annular grooves of the upper frame cover and the lower frame cover.

[0008] In some embodiments, the filter element has a thickness of H.

[0009] In some embodiments, the filter paper is folded and then bent into a cone to form the filter element.

[0010] In some embodiments, the air inlet cover is detachably mounted on the bottom of the housing.

[0011] In some embodiments, the air inlet cover includes a cover plate and a mounting portion extending upward along the cover plate, and the mounting portion is detachably connected to the housing.

[0012] In some embodiments, the inner wall of the bottom of the shell is provided with a plurality of locking protrusions toward the center, and the mounting portion is provided with a locking portion corresponding one-to-one to the locking protrusions; the locking protrusion rotates from the first position of the locking portion to the second position as the air inlet cover rotates; when the locking protrusion rotates to the second position, it cooperates with the air inlet cover along the vertical limit; when the locking protrusion rotates to the first position, it releases the limit cooperation with the air inlet cover.

[0013] In some embodiments, the locking portion includes an opening along the vertical direction and a locking slot extending along the rotational direction, the locking protrusion is located at the opening when in the first position, and is located inside the locking slot when in the second position.

[0014] Compared with the existing technology, the beneficial effect of the present invention is that by changing the air inlet hole of the outer shell to the air inlet cover located at the bottom of the air purifier, and changing the cylindrical filter to a conical filter, it can beautify the appearance of the purifier and facilitate cleaning. In addition, changing to a conical filter can increase the distance between the filter and the outer shell, without reducing the design size of the filter, and can maintain the performance of the purifier.

[0026] Reference Figure 1-7 , this embodiment provides an air purifier, comprising a housing 2, a filter 1 installed inside the housing 2, and an air inlet cover 3, wherein the air inlet cover 3 is installed at the bottom of the air purifier;

[0027] like Figure 3-6 As shown, the filter 1 includes an upper frame cover 11, a lower frame cover 13, and a filter element 12 connected between the upper frame cover 11 and the lower frame cover 13. The diameter of the lower frame cover 13 is smaller than that of the upper frame cover 11, and the lower perimeter of the filter element 12 is smaller than the upper perimeter, so that the filter 1 is enclosed into a conical filter 1;

[0028] In this embodiment, the filter element 12 is made of filter paper, the height of the filter paper is W, the filter paper is folded to a height of H, glued and fixed, and then cut into shape according to size. The lower circumference of the cut filter paper is smaller than the upper circumference, and then it is bent into a cone to form the filter element 12.

[0029] To mount the filter element 12 between the upper frame cover 11 and the lower frame cover 13 to form the filter 1, an annular groove 14 having a width H, which is the same as the thickness of the filter element 12, is defined on the opposing sides of the upper frame cover 11 and the lower frame cover 13. The upper and lower ends of the filter element 12 are respectively mounted within the annular grooves 14 of the upper frame cover 11 and the lower frame cover 13. The ends of the filter element 12 can be bonded to the annular grooves 14 using hot melt adhesive or AB adhesive, or other existing methods can also be used, without particular limitation as long as the objectives of this embodiment can be achieved.

[0030] After the air purifier has been used for a period of time, the air inlet cover 3 and the filter 1 will be covered with dust. Therefore, in order to facilitate the cleaning of the air inlet cover 3, in this embodiment, the air inlet cover 3 is detachably mounted on the bottom of the housing 2.

[0031] Specifically, if Figure 7 As shown, the air inlet cover 3 includes a cover plate and a mounting portion extending upwardly along the cover plate. The inner wall of the bottom of the housing 2 is provided with a plurality of center-facing locking protrusions 4. The mounting portion is provided with locking portions 31 corresponding one-to-one with the locking protrusions 4. The locking protrusions 4 rotate from a first position of the locking portion 31 to a second position as the air inlet cover 3 rotates.

[0032] The latching portion 31 includes an opening 311 extending vertically and a slot 312 extending in the rotational direction. The latching protrusion 4 is located within the opening 311 in the first position and within the slot 312 in the second position. Therefore, when the latching protrusion 4 is rotated to the second position, it engages with the air inlet cover 3 along the vertical limit, thereby installing the air inlet cover 3. When the latching protrusion 4 is rotated to the first position, it releases the limit engagement with the air inlet cover 3, allowing the air inlet cover 3 to be removed from the housing 2. As a simple alternative to this embodiment, the housing and the air inlet cover may also be connected using other detachable connection methods, such as threaded connections or snap-fit ​​connections, and are not limited to the detachable connection methods of this embodiment.

[0033] The above is only a preferred specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any technician familiar with the technical field who uses this concept to make non-substantial changes to the present invention within the technical scope disclosed by the present invention shall be deemed to infringe the protection scope of the present invention.
