The utility model discloses a protective device for a breather filtering assembly. The protective device comprises a substrate and a connecting mechanism, wherein the connecting mechanism is arranged on the substrate, and is suitable to be detachably connected with the filtering assembly, so that the filtering assembly can be arranged on the protective device temporarily for preventing the filtering assembly from being polluted. On another aspect, the utility model provides a breather with the protective device.
Description
Technical field
The utility model relates to a kind of respirator parts, more specifically, relates to a kind of protective device of respirator filter assemblies, and the respirator that adopts this protective device.
Background technology
Respirator (being commonly called as face shield) is widely used in the various occasions that need respiratory protection, as has the environment of dust, pernicious gas, so that inhaled air filters.Therefore, respirator generally has filter assemblies, and is normally removable, wherein contains filtering material.
The maintenance of respirator is except in good time replacing filter assemblies, and the cleaning of respirator body also is important.When cleaning the respirator body, the filter assemblies that unloads normally one have an opening box body, the protection of its opening portion becomes needs the problem that solves, in order to avoid filtering material is polluted by the opening part from filter assemblies.
A kind of 3M
TMBreathe Easy
TMThe used filter tank of electronic blast type respiratory system (as: AEP3 type) is used to protect filter tank not contaminated having an over cap with the respirator link.
In many cases, respirator has two filter assemblies, therefore need all protect two filter assemblies.
The utility model content
The purpose of the utility model provides a kind of protective device of easy respirator filter assemblies, so that need unload under the situation of filter assemblies cleaning respirator body etc., to filter assemblies protection is provided.
An aspect according to the utility model; A kind of protective device of respirator filter assemblies is provided; Comprise a substrate and syndeton, this bindiny mechanism is arranged on the said substrate and is suitable for removably being connected with said filter assemblies that to make that said filter assemblies can be arranged to said protective device provisionally contaminated to prevent said filter assemblies.Thus, can the filter assemblies that unload be installed on the substrate, the coupling part of sealing filter assemblies, for example opening portion protects filter assemblies not contaminated.
According to the utility model, can form a said bindiny mechanism in each side of substrate respectively, can install and protect two filter assemblies to get into its inside so simultaneously, and closely connect two filter assemblies to prevent loss wherein one to prevent pollutant.
According to another aspect of the utility model, a kind of respirator with this protective device is provided.
The utility model is that the filter assemblies of respirator provides protection, and it can be used for one also can be used for two filter assemblies simultaneously.Its volume is little, and is easy to manufacture, easy to use.
Description of drawings
Fig. 1 is the sketch map of protective device of a kind of respirator filter assemblies of the utility model;
Fig. 2 is bindiny mechanism's sketch map of protective device of a kind of respirator filter assemblies of the utility model;
Fig. 3 is the sketch map before the protective device of a kind of respirator filter assemblies of the utility model is connected with two filter assemblies.
The specific embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.In specification, same or analogous drawing reference numeral is represented same or analogous parts.Followingly the explanation of the utility model embodiment is intended to the overall utility model design of the utility model is made an explanation, and is not to be understood that and is any restriction the utility model with reference to accompanying drawing.
According to an embodiment of the utility model, a kind of protective device of respirator filter assemblies is as depicted in figs. 1 and 2, has a substrate 1; It can be to be disc or other shapes; Protective device also is included in the side formation of substrate 1 or the bindiny mechanism that is provided with, and it is used to connect filter assemblies, for example is connected to the opening portion of filter assemblies; So that filter assemblies is placed on the protective device temporarily, prevent that said filter assemblies is contaminated.
Also can respectively form a bindiny mechanism in the both sides of substrate 1, it is respectively applied for and connects filter assemblies so that two filter assemblies are placed on the protective device.In this example; Bindiny mechanism is included in the ring-type fixed structure of the projection that is formed centrally in the discoidal substrate 1; Especially buckle-type annular fixed structure 2; The clamping part 2-1 that has 3 convexities on it is suitable for being connected with the corresponding coupling part of filter assemblies, for example matches with 6000 series and the 7000 serial mask filter assemblies links that 3M company sells.This clamping part can be realized with common mode.
In this example, the bindiny mechanism that the both sides of substrate 1 form can be identical and symmetrical, but also can form asymmetric or inequality.And; The fixed structure of one or two bindiny mechanism can be to be threaded rather than the buckle-type connection; Promptly on the ring-type fixed structure that substrate center's projection forms, form hickey; This thread fixing structure can be realized with common mode, and matched with the filter assemblies that has hickey accordingly.
According to an aspect of the utility model, the bindiny mechanism that forms on the substrate forms respectively in both sides like this example, but also can only form at the substrate either side, seals the opening of filter assemblies through substrate.
According to another aspect of the utility model, when the both sides of substrate 1 respectively form a bindiny mechanism, can in substrate 1, be formed centrally through hole 1-1, be convenient to form the ring-type fixed structure, like the snap fit structure 2 in this example at through hole 1-1 edge.During use, two filter assemblies 4 are installed simultaneously, the closed peristome branch is as shown in Figure 3 mutually.Certainly, also can form through hole 1-1, benefit is to be used to protect single filter assemblies.
According to another aspect of the utility model, at least one said bindiny mechanism have one be suitable for sealing said filter assemblies sealing gasket 3, help being placed in the coupling part of protective device rear enclosed filter assemblies like this, for example opening at filter assemblies.Sealing gasket 3 is in snap fit structure 2 all edges, for example can be arranged in the groove 1-2 that forms on the substrate 1, and is as illustrated in fig. 1 and 2.Bindiny mechanism for adopting thread fixing structure obviously also can be provided with sealing gasket equally.
As shown in Figure 3 when using according to the protective device of a kind of respirator filter assemblies of present embodiment, two filter assemblies are installed on the substrate 1 through snap fit structure 2 from the both sides of substrate 1 respectively, the state before connecting has been shown among Fig. 3.
According to the utility model, protective device can offer existing respirator and use, and perhaps, according to another aspect of the utility model, a kind of respirator with filter assemblies protective device of the utility model is provided.
According to the utility model, though combine accompanying drawing that the utility model is illustrated, disclosed embodiment is intended to the utility model preferred implementation is carried out exemplary illustration in the accompanying drawing, and can not be interpreted as a kind of restriction to the utility model.
Though the embodiment of the utility model general plotting is illustrated and explains; Those skilled in the art will appreciate that; Under the situation of principle that does not deviate from the utility model design and spirit, can make a change embodiment, the scope of the utility model limits with claim and their equivalent.
