Description

Detachable filter device for fans

The invention relates to a detachable filter device used for a fan.

In general, the electric fan is one of the household appliances necessary for modern families. In order to meet the needs of various environments, the electric fan also has many styles, such as a standing vertical fan and a box fan, which can be installed on the table. On the table type fan, etc. In addition, as the Chinese people's demand for air environment and health rises, there is a fan filter on the market for hanging the fan, so that the air passes through the fan filter to filter the air when the fan rotates Dust and impurities, such as the fan filter disclosed in the patent number TW553325, belong to this category.

However, this type of fan filter can only be hung for fans of a single model size. Fans of different model sizes and corresponding fan filters need to be purchased to hang them smoothly, which is not only inconvenient to use and will cause consumption The difficulty in purchasing, which leads to consumers' lack of willingness to buy, there are shortcomings that need to be improved.

Therefore, it is necessary to provide a novel and progressive detachable filter device for fans to solve the above problems.

The main purpose of the present invention is to provide a detachable filter device for fans, which can be hung on fans of different sizes and shapes, so it is very convenient to use and has a simple structure, which can increase consumers' willingness to purchase.

To achieve the above object, the present invention provides a detachable filter device for a fan, which includes a body and at least one filter element. The body includes two parts, each of which has a first end and a second end opposite to each other, the first ends of the two parts are pivotally arranged, the two parts have an inner side facing each other and a far side away from each other An interval is defined between the two inner sides, and the interval between the two inner sides is changed by swinging the two second ends to allow the two inner sides to straddle a motor head of a fan. The at least one filter element is provided on at least one of the two parts.

The following merely illustrates the possible implementation forms of the present invention with examples, but it is not intended to limit the scope of the invention to be protected, and will be described first.

Please refer to FIGS. 1 to 12, which show a preferred embodiment of the present invention. The detachable filter device for a fan of the present invention includes a body 8 and at least one filter element 41.

The body 8 includes two parts 1, each of the parts 1 has a first end 11 and a second end 12 opposite to each other, the first ends 11 of the two parts 1 are pivotally arranged, and the two parts 1 have a facing each other The inner side 13 is separated from the outer side 14 by a phase, and a gap 15 is defined between the two inner sides 13, and the gap 15 between the two inner sides 13 is changed in size by the two second ends 12 swinging to provide the two The inner side 13 straddles a motor base 91 of a fan 9.

The at least one filter element 41 is disposed on at least one of the two components 1. In this embodiment, the two components 1 are each provided with a filter element 41. By pivotally setting the first ends 11 of the two components 1, the inner side 13 of the two components 1 can be straddled on motor seats 91 of different sizes. Therefore, the present invention is very convenient in use and has a simple structure, which can improve consumers Purchase intention.

It is worth mentioning that, preferably, the filter element 41 is a filter screen 411, which is coated with nano-photocatalyst paint (not shown), and each of the components 1 is provided with a light-emitting component 5, in this embodiment In the example, each of the light-emitting components 5 is two LED light-emitting light bars. When the light-emitting component 5 emits light, the nano-photocatalyst paint can produce a strong oxidation effect, so that the dirt or organic matter attached to the filter 411 is decomposed into water And carbon dioxide, to eliminate bacteria, viruses, mold and other microorganisms in the air, and can decompose formaldehyde and various organic gases and nitrogen oxides, etc., in order to effectively achieve the function of purifying the air.

Specifically, in this embodiment, one of the first ends 11 is provided with a first pivot portion 16, the other of the first ends 11 is provided with a second pivot portion 17, and a pivot member 21 passes along an axis 22 The first pivot portion 16 and the second pivot portion 17 are provided.

Preferably, one of the first pivot portion 16 and the second pivot portion 17 is provided with a first latching portion 23, and the other is slidingly provided with a second latching portion 24, the second latching portion 24 may be Sliding along the axial direction 22 at a first position and a second position, when the second clamping portion 24 is located at the first position, the first clamping portion 23 and the second clamping portion 24 snap , The two parts 1 cannot rotate relatively, so as to prevent the two parts 1 from swinging arbitrarily and falling from the motor base 91; when the second clamping portion 24 is in the second position, the first clamping portion 23 does not When the second clamping tooth portion 24 abuts, the two components 1 can rotate relatively, and the size of the gap 15 can be adjusted.

In this embodiment, an elastic member 25 is further included. The elastic member 25 is resiliently disposed between the second clamping portion 24 and one of the components 1 to normally move the second clamping portion 24 toward the first A position against the top to normally lock the two components 1 to avoid any swinging, the pivot 21 is a pivot, the pivot 21 can be selectively opposite to the first pivot 16 and the second along the axis 22 The pivot portion 17 slides, and when the pivot member 21 is pressed, the second clamping portion 24 can be pressed toward the second position (as shown in FIGS. 9 and 10 ), so the operation process is simple.

Further, each of the components 1 includes a first casing 31 and a second casing 32, the first casing 31 and the second casing 32 are assembled, the first casing 31 and the second casing The housing 32 encloses an accommodating space 33, and the filter element 41 is accommodated in the accommodating space 33. One of the first casing 31 and the second casing 32 is provided with an insertion port 34 through which the filter element 41 is inserted into the accommodating space 33, so there is no need to separate the first casing 31 and the After the second housing 32 is disassembled, the filter element 41 can be detached.

Wherein, the first casing 31 is provided with at least one first locking portion 35 at the second end 12, and the second casing 32 is provided with at least one corresponding to the first locking portion 35 at the second end 12 The second buckling portion 36 of the buckle is used to assemble the first housing 31 and the second housing 32. In this embodiment, two first buckling portions 35 and two second buckles are provided Buckle 36.

Preferably, the detachable filtering device for the fan 9 further includes two cover members 42 and two interlayers 43, and the two cover members 42 cover the two first housings 31 and the two second housings 32, respectively One of them is to sandwich the two interlayers 43 between the two components 1. In this embodiment, the two interlayers 43 are filter layers, so that the detachable filter device used for the fan has a more filtering effect. In the embodiment, each of the interlayers 43 may also be other articles such as fragrance tablets. Each of the cover members 42 is provided with a plurality of protrusions 44, each of the second housings 32 is provided with a plurality of insertion holes 45, and each of the protrusions 44 is inserted into one of the insertion holes 45 to facilitate disassembly and assembly.

In summary, the detachable filter device for the fan of the present invention can be provided for the inner ends of the two components to span across motor seats of different sizes by pivoting the first ends of the two components, so the present invention is used in It is very convenient and simple in structure, which can increase consumers' willingness to buy. Moreover, in the present invention, the two components can be locked normally to avoid any swing. When the pivot member is pressed, the second clamping portion can be pressed toward the second position, so the operation process is simple.
