Description
Technical field
The utility model belongs to cleaner technical field, is specifically related to a kind of good airproof performance, secondary seal cleaner that filter efficiency is high.
Background technology
The most cleaner of current use, all filter core and shell compositions, the sealing of this cleaner is directly sealed by the sealing ring of planar shaped, and the sealing between end cap and thread plate assembly is not good especially, long-time use bonnet sealing circle Long-Time Service after, sealing ring is yielding, there is leakage hole, and during the installation of sealing circle, displacement may be occurred in the process of tightening, have impact on sealing effectiveness.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is the secondary seal cleaner providing a kind of good airproof performance, filter efficiency high.
Described a kind of secondary seal cleaner, comprise filter body, described filter body bottom interval arranges one group of collecting bowl, filter body upper end arranges the thread plate sub-unit and end cap that are connected and fixed, between thread plate sub-unit and end cap, sealing ring is set, it is characterized in that sealing circle comprises sealing ring body, sealing ring bodies top arranges longitudinal projection, this longitudinal direction is protruding to be connected with the inside corners place of thread plate sub-unit, sealing ring body bottom portion arranges inwardly outstanding lateral projection, sealing ring body bottom portion arranges arranged outside concave step, the outer corner of this concave step and end cap is connected.
Described a kind of secondary seal cleaner, is characterized in that described concave step arranges chamfering, and this chamfering place radius of a circle is 1mm.
Described a kind of secondary seal cleaner, is characterized in that described concave step is provided with chamfering, and this chamfering place radius of a circle is 1mm, and the height of concave step is 4mm.
Described a kind of secondary seal cleaner, is characterized in that described lateral projection inwardly outstanding 3-4mm.
Described a kind of secondary seal cleaner, it is characterized in that described longitudinal projection raises up is highly 4-5mm.
Above-mentioned a kind of secondary seal cleaner, comprise filter body, filter body bottom interval arranges one group of collecting bowl, filter body upper end arranges the thread plate sub-unit and end cap that are connected and fixed, between thread plate sub-unit and end cap, sealing ring is set, sealing circle comprises sealing ring body, sealing ring bodies top arranges longitudinal projection, this longitudinal direction is protruding to be connected with the inside corners place of thread plate sub-unit, sealing ring body bottom portion arranges inwardly outstanding lateral projection, sealing ring body bottom portion arranges arranged outside concave step, the outer corner of this concave step and end cap is connected.The utility model by sealing ring horizontal and vertical on projection is set, and concave step is set, adopt secondary seal, make sealing ring concentric with screw thread, played the effect of sealing by filter block radial seal, and specifically define its size, improve sealing ring and the connection compactness between thread plate sub-unit and end cap, prevent screw thread from leaking, improve its sealing property, ensure cleaner filter efficiency.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is ring structure schematic diagram of the present utility model.
In figure: 1-thread plate sub-unit, 2-sealing ring, 201-is longitudinally protruding, 202-sealing ring body, 203-concave step, 204-lateral projection, 3-end cap, 4-filter body, 5-collecting bowl.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model will be further described, but protection domain of the present utility model is not limited in this:
As shown in Figure 1-2, secondary seal cleaner of the present utility model, comprise filter body 4, described filter body 4 bottom interval arranges one group of collecting bowl 5, filter body 4 upper end arranges the thread plate sub-unit 1 and end cap 3 that are connected and fixed, sealing ring 2 is set between thread plate sub-unit 1 and end cap 3, as shown in Figure 2, sealing circle 2 comprises sealing ring body 202, sealing ring body 202 top arranges longitudinally projection 201, this longitudinal direction protruding 201 is connected with the inside corners place of thread plate sub-unit 1, this longitudinal projection 201 is circular arc smooth structure, be convenient to sealing, inwardly outstanding lateral projection 204 is set bottom sealing ring body 202, arranged outside concave step 203 is set bottom sealing ring body 202, this concave step 203 is connected with the outer corner of end cap 3.
In order to improve the connection compactness of sealing ring 2 and thread plate sub-unit 1 and end cap 3 further, the utility model limits the size on sealing ring, by in concave step 203, chamfering is set, this chamfering place radius of a circle is 1mm, the height of concave step 203 is 4mm, lateral projection 204 is outstanding 3-4mm inwardly, and longitudinally projection 201 raises up is highly 4-5mm.
Cleaner of the present utility model is by improving the structure of sealing ring, sealing circle 2 is placed between thread plate sub-unit 1 and end cap 3, the effect of sealing is played by filter block radial seal, it is concentric with screw thread that end cap adopts positioning convex point to guarantee to make sealing ring, adopt above-mentioned secondary seal, can effectively prevent screw thread from leaking, ensure the clear device filter efficiency of filter.
