Description

Multipurpose gas filter

Technical Field

The utility model relates to a filter field, concretely relates to multipurpose gas filter.

Background

A gas filter is a widely used component in medical devices for filtering impurities and microorganisms in gases. The gas filter is internally provided with a filter cavity, and a filter membrane is arranged in the filter cavity.

Most of the existing gas filters are connected with equipment, so that the interfaces of the existing gas filters are only provided with a trapezoidal hose interface connected with the equipment, and when an injector is possibly adopted in an emergency, the trapezoidal hose interface cannot be matched with the injector, so that the gas filters with different interfaces need to be replaced, the efficiency is influenced, and the cost is increased.

SUMMERY OF THE UTILITY MODEL

To the not enough of prior art existence, the utility model aims to provide a multipurpose gas filter.

In order to achieve the above purpose, the utility model provides a following technical scheme:

the utility model provides a multipurpose gas filter, includes upper cover and lower cover, the upper cover forms the chamber with the lower cover lock, install filtering diaphragm in the chamber, filtering diaphragm falls into the chamber and admits air the room with the chamber, upper cover and lower cover all are equipped with the joint of giving vent to anger, it is equipped with the coaxial second interface that is used for the first interface of equipment connection and is used for moulding plastics the utensil connection that sets gradually to give vent to anger to connect.

The first interface is a hose interface which is arranged on the outer surface of the air outlet joint and has a trapezoidal axial section, and the hose interface is arranged along the axial direction of the air outlet joint.

A gap is arranged between two adjacent hose connectors at the rear end of the air outlet joint.

The diameter of the hose connector is sequentially increased from the front end to the rear end of the air outlet connector.

The diameter of the hose connector is 3-13 mm.

And a second interface is arranged on the inner wall of the front end of the air outlet joint.

The second hub is a 6:100 luer or a 5:100 luer.

The utility model has the advantages that: through set up two kinds of interfaces on giving vent to anger the connector to satisfy the connection use of equipment or injection apparatus, realize that gas filter's connected mode is diversified.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that all the directional indicators (such as upper, lower, left, right, front and rear … …) in the embodiment of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indicator is changed accordingly.

In the present application, unless expressly stated or limited otherwise, the terms "connected" and "fixed" are to be construed broadly, e.g., "fixed" may be fixedly connected or detachably connected, or integrally formed; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be connected internally or in any other suitable relationship, unless expressly stated otherwise. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In addition, descriptions in the present application as to "first", "second", and the like are for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicit to the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

As shown in the figure, the utility model provides a multipurpose gas filter, including upper cover and lower cover, upper cover 1 forms the cavity with 3 locks of lower cover, and the upper cover constitutes to dismantle sealing connection with the lower cover, install filtering diaphragm 2 in the cavity, upper cover and lower cover are fixed filtering diaphragm simultaneously, and by filtering diaphragm falls into filtering chamber and air inlet chamber with the cavity, upper cover and lower cover all are equipped with the joint 4 of giving vent to anger, the joint of giving vent to anger is equipped with coaxial second interface 6 that is used for equipment connection's first interface 5 and is used for moulding plastics the utensil connection that sets gradually.

The air outlet joint is provided with at least a plurality of interfaces, so that the single air outlet joint can meet the requirements of equipment and injection appliances.

The first interface is a hose interface which is arranged on the outer surface of the air outlet joint and has a trapezoidal axial section, and the hose interface is arranged along the axial direction of the air outlet joint. The first interface is used for being connected with equipment, and the depth of inserting the equipment guide pipe into the first interface through the air outlet connector is different, so that the connection requirements of different equipment guide pipes can be met. Be located to give vent to anger and be equipped with the clearance between two adjacent hose connectors of joint rear end, utilize to set up the clearance, the area of contact of two hose connectors around the extension for it is more firm to fix.

The diameter of the hose connector is sequentially increased from the front end to the rear end of the air outlet connector, the diameter of the hose connector is 3-13mm, and the connection of different devices is met by sequentially increasing the hose connectors.

The inner wall of the front end of the air outlet joint is provided with the second interface, the injector interface is arranged on the inner wall, direct interference with the first interface is avoided, meanwhile, the size of the air outlet joint is better utilized, and the adapter of the injector with the smaller diameter is realized.
