Description

A kind of filter

Technical field

The utility model belongs to air filter unit technical field, and in particular to a kind of filter.

Background technology

At present, air pollution constantly aggravates, and haze weather increasingly increases, and the emergence of deadly infectious disease, causes Containing the multiple-microorganism and contaminative dust being detrimental to health in air, this just proposes higher want to purification of air Ask, and the popularization to PM2.5, entire society have higher requirement for air purification effect.

Existing air filter, to be fixedly connected between several filter layers, wherein some filter layer occur blocking or , it is necessary to change whole filter when person's effect is bad, the increase of cost and the waste of resource are caused；In addition, existing filtering Device, pre-filtering is not carried out to air, entered directly into filter, this can cause filter easily to block；It is existing Filter, filter effect is poor.

Therefore, it is necessary to be improved to existing filter, enable to filter filter effect preferably same When can change its part, economize on resources.

Utility model content

Insufficient present in background technology in order to overcome, the utility model proposes a kind of filter, can strengthen to sky The filter effect of gas, and part therein can be changed, economize on resources.

In order to achieve the above object, the utility model is achieved through the following technical solutions：

A kind of filter includes pre-filtering plate, the first filter and the second filter from outside to inside, described pre- mistake Fixed support is provided with front side of filter plate, four angles of pre-filtering plate, the first filter and the second filter offer fixation respectively Hole,

Pre-filtering plate, the first filter and the second filter are attached by fixed pin through fixing hole, the second filter Thickness be pre-filtering plate and the first filtering three times of plate thickness,

The first filter core is provided with the middle part of described pre-filtering plate, filter opening is provided with the first filter core, filter opening is gradually to pre- mistake The filter plate back side is collapsed,

It is provided with filtering frame in the first described filter, described filtering frame is raised zigzag, described filtering The filter bag of arc is provided with buck saw bottom angle,

It is provided with the second described filter and is disposed with HEPA high efficiency filter layers, activated carbon filter layer and end mistake Filtering layer, the consistency of thickness of HEPA high efficiency filter layers, activated carbon filter layer and end filtration layer.

Further, the area of the first described filter core is less than the area of pre-filtering plate, the thickness of the first filter core and pre-filtering The consistency of thickness of plate.

Further, the fleam of described filtering frame is 60-90 degree.

Further, described filter bag is located at the back side of filtering frame.

Further, filtering frame rear portion is provided with non-woven fabrics filter layer in the first described filter.

Further, mounting hole is provided with described fixed support, fixed support is provided with solid in pre-filtering plate side-walls Determine groove, fixed groove is consistent with pre-filtering plate width.

Compared with prior art, the utility model one of at least has the advantages that：

1. being provided with pre-filtering plate, air can be subjected to pre-filtering, the big impurity in air is filtered, and in advance Filter side-walls are provided with fixed groove, can be dual by pre-filtering plate and the progress of the first filter by fixed pin and groove Filtering, preferably pre-filtering plate and the first filter can be fixed, and strengthen stability；

, can be in the case where avoiding large granular impurity from entering together 2. the filter opening of pre-filtering plate gradually collapses to pre-filtering back In filter and the blocking of pre-filtering plate can be avoided；

3. being provided with the filter bag of arc in the first filter at the filtering frame fleam, solve angle flying dust and hold Easily hoard the shortcomings that causing filter effect to be deteriorated；

4. HEPA high efficiency filter layers, activated carbon filter layer and end filtration layer are disposed with the second filter, can Strengthen the filter effect of air；

5. the utility model is provided with three filters, air is first subjected to pre-filtering, then once filtered again and Secondary filter so that the air quality after filtering is higher.

Brief description of the drawings

Fig. 1 is the utility model structure diagram；

Fig. 2 is that the utility model first filters plate structure schematic diagram；

Fig. 3 is that the utility model second filters plate structure schematic diagram.

1- pre-filterings plate, the filters of 2- first, the filters of 3- second, 4- fixed pins, 5- fixed supports, 6- are fixed in figure Hole.

Embodiment

In order that the purpose of this utility model, technical scheme and beneficial effect are clearer, below in conjunction with accompanying drawing, to this The preferred embodiment of utility model is described in detail, to facilitate the technical staff to understand.

As Figure 1-3, described filter includes pre-filtering plate 1, the first filter 2 and the second mistake from outside to inside Filter plate 3, the described front side of pre-filtering plate 1 are provided with fixed support 5, mounting hole are provided with fixed support 5, fixed support 5 exists The side-walls of pre-filtering plate 1 are provided with fixed groove, and fixed groove is consistent with the width of pre-filtering plate 1, and pre-filtering plate 1, first filters Four angles of the filter 3 of plate 2 and second offer fixing hole 6 respectively,

Pre-filtering plate 1, the first filter 2 and the second filter 3 are attached by fixed pin 4 through fixing hole 6, the second mistake The thickness of filter plate 3 is three times of the thickness of 1 and first filter of pre-filtering plate 2, can be by fixed pin 4 and groove by pre-filtering plate 1 and first filter 2 carry out double filtration, preferably the filter 2 of pre-filtering plate 1 and first can be fixed, enhancing is steady It is qualitative；Air is first subjected to pre-filtering, then once filtered again and secondary filter so that the air quality after filtering It is higher.
