Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present invention is an air purifier with an external filter element, including an upper casing 1, a fan 2 is installed inside the upper casing 1, and the fan 2 is driven by an internal motor to rotate blades at a high speed, so as to form a negative pressure; more importantly, the upper shell 1 is integrally installed on the supporting column 3, then the supporting column 3 is installed on the base 4, furthermore, a first air duct 5 is arranged inside the upper shell 1, the first air duct 5 is communicated with the air outlet 6, the air outlet 6 is preferably designed at the top of the upper shell 1 as shown in fig. 1, meanwhile, the supporting column 3 is designed into a hollow structure, a second air duct 7 is designed inside the supporting column 3, and the second air duct 7 is communicated with the first air duct 5; then, an air inlet is designed on the support column 3, the air inlets can be designed into a plurality of shapes which are uniformly distributed on the support column 3, or the air inlets can be designed into a special shape, or the support column 3 is directly designed into a bracket, a large-area gap is formed between the brackets, and the gap is used as the air inlet. Based on the structure of the support column 3, a filter element body 8 can be sleeved outside the support column 3, the air inlet is covered by the filter element body 8, and then the air inlet is communicated with the outside through any position of the filter element body 8, so that when the fan 2 rotates to generate negative pressure, outside air enters the second air channel 7 through any position of the filter element body 8, then enters the first air channel 5 and is discharged through the air outlet 6, and filtering is completed.

Furthermore, about the air intake on above-mentioned support column 3, it needs to explain very much, the utility model discloses a mention in the background art, air intake on the shell body of the lower part of the similar air purifier product can be because the size of air intake and overall arrangement mode scheduling problem form the hindrance to the air current when the air inlet, and then produce the noise easily when the air inlet, and in the structure of the utility model, the inboard of filter element body 8 is arranged in to the air intake on the support column 3, even consequently the air current has produced the noise when getting into second wind channel 7 by the air intake, the noise does by encircleing at the outside filter element body 8 separation of support column 3, and external filter element body structure can also play syllable-dividing technological purpose promptly.

Preferably, the entire shape of the filter element body 8 may be designed to be cylindrical in order to maintain the aesthetic appearance of the air cleaner product. The adult shape of the support column 3 is designed as a hollow circular tube shape, and then the outer contour of the upper case 1 is rounded. The design of the air purifier product is close to the external shape of the like products on the market at present.

And in this embodiment, through with filter element body 8 suit on support column 3, make filter element body 8 expose outside, the air current can get into the second wind channel 7 of support column from filter element body 8's optional position, thereby can increase its dust holding space under the circumstances that does not increase the filter core volume, promote the air filter effect, also can avoid the narrow wind noise that causes of intake, the lower part shell has been saved to the air purifier structure after this embodiment improves simultaneously, and can reduce manufacturing cost, and parts have reduced the assembly degree of difficulty, also be convenient for the user to change the filter core when using.

Referring to fig. 2, in a more preferred embodiment of the present invention for solving the above-mentioned problems, the inventor further adds a sealing means to the upper and lower portions of the filter element body 8 to prevent the air flow from entering the second air duct 7 from the lower side of the upper housing 1 and the gap between the upper side of the base 4 and the filter element body 8, specifically, adds a sealing ring 9 to the position where the lower side of the upper housing 1 contacts the upper portion of the filter element body 8, and similarly, adds a sealing ring 9 to the position where the upper side of the base 4 contacts the lower portion of the filter element body 8. The sealing ring can keep the filter element body 8 in close contact with the base 4 and the upper shell 1, and unfiltered air enters the second air channel 7. Meanwhile, as shown in fig. 2, in the present embodiment, for further prolonging the service life of the filter element body 8, the inventor further installs a layer of annular filter cloth 10 between the lower side of the upper housing 1 and the upper side of the base 4 on the basis of the above structure, and places the annular filter cloth 10 outside the filter element body 8. This annular filter cloth 10 not only can carry out the coarse filtration to the air that gets into filter element body 8, still can promote the wholeness of whole air purifier product, based on aforementioned thinking, still adds one on annular filter cloth 10's outer fringe and gets to take the sack to conveniently get and take air purifier, it is regional as the mark of air purifier brand to do this region.

Furthermore, in order to facilitate the disassembly of the annular filter cloth 10, an annular step 11 may be disposed on both the lower side of the upper housing 1 and the upper side of the base 4, and then the upper portion and the lower portion of the annular filter cloth 10 are respectively sleeved on the annular step 11 by elastic binding bands. Can pull down annular filter cloth 10 when using like this and wash the outside of airing the back dress at filter element body 8 again to reduce the consumptive material consumption in the air purifier use, and resource reuse, environmental protection more. On the other hand, in the present embodiment, in order to facilitate replacement of the filter element body 8, the support column 3 may be detachably mounted on the lower portion of the upper housing 1 and/or the upper portion of the base 4 in terms of component design.

Referring to fig. 2 and 3, in practical use, according to the above preferred embodiment of the present invention, after the power supply of the fan 2 is turned on, negative pressure is generated in the first air duct 7 and the second air duct 7, and under the action of the negative pressure, air outside the filter element body 8 firstly passes through the annular filter cloth 10, then enters the second air duct 7 from any position of the filter element body 8, and is discharged from the air outlet 6 through the first air duct 5; in the process, each part of the filter element body 8 is fully utilized to filter the airflow so as to increase the utilization rate of the filter element body 8 when the air purifier is used; after the air purifier is used for a period of time, the annular filter cloth 10 can be detached from the annular step 11, cleaned, aired and continuously mounted on the annular step 11 for use; and because the air current carries out coarse filtration through annular filter cloth 10 at first, therefore most large granule impurity in the air can all stay on annular filter cloth 10 for the life cycle of filter element body 8 lengthens, and when needing to change filter element body 8, directly pull down annular filter cloth 10, and take off support column 3 from base 4, can change the filter element body 8 of suit at the outside of support column 3, change the suit again after the completion on annular filter cloth 10 can. That is, the utility model provides a pair of with the air purifier product of the same kind on the market on the use principle and the use method basically similar, and the utility model discloses owing to saved the lower part shell body, promoted filter element body 8 hold dirt space and utilization ratio, promote filtration efficiency, also reduced manufacturing cost to filter element body 8 still assists the effect of playing the amortization.
