Abstract
The utility model provides a laminar flow purifying device, comprising a working box body and a filter box body located at the top of the working box body, wherein a centrifugal fan is contained inside the laminar flow purifying device; a first filter is arranged at the top of the centrifugal fan; a second filter and an ultraviolet sterilizing lamp are arranged at the lateral part of the centrifugal fan; a plurality of third filters are arranged between the working box body and the filter box body; the lateral wall of the working box body is hollow; at least one air return hole is arranged on the lateral wall of the working box body; and the air return hole is communicated with an air inlet pipe of the centrifugal fan. According to the laminar flow purifying device provided by the utility model, at least one air return hole is formed on the lateral wall of the working box body of the laminar flow purifying device, which is near the bottom, and the lateral wall of the working box body is in a hollow structure, so that the air return hole is communicated with the air inlet pipe of the centrifugal fan through the hollow lateral wall, air turbulent flow can be effectively removed, and the air purifying effect of the laminar flow purifying device can be improved.
Description
Technical field
The utility model relates to a kind of purifier, relates in particular to a kind of clean by laminar flow device.
Background technology
As everyone knows, the clean by laminar flow device is a kind of a kind of purifier that uses in the cleaning shop.It can circulate to the air in the little space of partial closure and filter, and in order to improve the suspended particulate in the filtered air, to improve air quality, prevents that airborne suspended particulate from polluting biological products.
Clean by laminar flow device of the prior art generally is the top air-out, and at top return air.But this clean by laminar flow unit in actual use, and purifying air that the top blows out can be polluted by the biological sample in the laminar flow device.And the inner meeting generation of the clean by laminar flow device of this " top is sent and pushed up back " air disturbance, thereby cause clean air can be entrained in unfiltered air, thus cause the clean-up effect of clean by laminar flow device not good.
In view of this, be necessary clean by laminar flow device of the prior art is improved, to address the above problem.
The utility model content
The purpose of this utility model is to provide a kind of clean by laminar flow device, in order to eliminating air disturbance, thereby improves its air purification effect.
For achieving the above object, the utility model provides a kind of clean by laminar flow device, comprising:
Working box, be positioned at the filter box at working box top, centrifugal blower is accommodated in its inside, described centrifugal blower top arranges the first filter, described centrifugal blower sidepiece arranges between the second filter and ultraviolet sterilization lamp, described working box and the filter box and also is provided with some the 3rd filters, described working box sidewall hollow, its sidewall is provided with at least one return air hole, and described return air hole is connected with the blast pipe of centrifugal blower.
As further improvement of the utility model, described the first filter is nonwoven.
As further improvement of the utility model, described the second filter is bag filter.
As further improvement of the utility model, described the 3rd filter is the high efficiency plate filter.
Compared with prior art, the beneficial effects of the utility model are: in the utility model, near on the sidewall of bottom at least one return air hole is set by the working box with this clean by laminar flow device, and the sidewall of working box is arranged to hollow structure, thereby return air hole is connected with the blast pipe of centrifugal blower by the sidewall of hollow, thereby effectively eliminated air disturbance, thereby improved the air purification effect of this clean by laminar flow device.
Description of drawings
Fig. 1 is the structural representation in the utility model clean by laminar flow device one specific embodiment.
The specific embodiment
Below in conjunction with each embodiment shown in the drawings the utility model is elaborated; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skills all belong within the protection domain of the present utility model according to these embodiment institute work energy, method or structural equivalent transformation or alternative.
Shown in please refer to the drawing 1, wherein Fig. 1 is the structural representation in the utility model clean by laminar flow device one specific embodiment.In the present embodiment, a kind of clean by laminar flow device 100 comprises:
As preferred embodiment, this first filter 202 is nonwoven; This second filter 203 is bag filter; The 3rd filter 30 is the high efficiency plate filter.Concrete, be provided with three high efficiency plate filters between this working box 10 and the filter box 20.
Concrete, this working box 10 also is provided with a body 102.This body 102 can be glass door and also can be stainless steel door.
In the utility model, near on the sidewall of bottom at least one return air hole 101 is set by the working box 10 with this clean by laminar flow device 100, and the sidewall of working box 10 is arranged to hollow structure, thereby return air hole 101 is connected with the blast pipe 2011 of centrifugal blower 201 by the sidewall of hollow, thereby effectively eliminated air disturbance, thereby improved the air purification effect of this clean by laminar flow device 100.
Above listed a series of detailed description only is specifying for feasibility embodiment of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent embodiment or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that do not deviate from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, therefore is intended to include in the utility model dropping on the implication that is equal to important document of claim and all changes in the scope.Any Reference numeral in the claim should be considered as limit related claim.
In addition, be to be understood that, although this specification is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, and the technical scheme among each embodiment also can through appropriate combination, form other embodiments that it will be appreciated by those skilled in the art that.
