Summary of the invention
The purpose of this utility model is the problems referred to above existed for existing conversion of blowing, and proposes one and namely insert and namely turn, and the air blowing syndeton of the simple dust catcher of structure.
The purpose of this utility model realizes by following technical proposal: a kind of air blowing syndeton of dust catcher, it comprises and is located at air chamber in dust catcher head capsule and is connected on head capsule and the outer tube connected with air chamber, described air chamber has air intake passage and loose wind passage, it is characterized in that, described air chamber is also provided with an insufflation channel straight up, insufflation channel covers airtight with diaphragm seal, the center of diaphragm seal is provided with mesopore, and in mesopore, be arranged with the tubular air blowing body of a back cover, described gas blow pipe physical efficiency to slide up and down and top is docked with outer tube along diaphragm seal, air blowing body is provided with back-moving spring between gentle room, the two ends of back-moving spring connect bottom surface and the air blowing body bottom surface of air chamber respectively, and body bottom surface of blowing to upper limit on diaphragm seal, the lower end sidewall of described air blowing body is provided with and connects pore, when air blowing body presses down, described company's pore is pushed in air chamber, the limit wall of air blowing body then blocks the loose wind passage of air chamber.
When outer tube presses down, be pushed in air chamber by connecting pore, the wind of air chamber is changed to by original loose wind passage and connects in pore, and blows out through outer tube.
In the air blowing syndeton of above-mentioned a kind of dust catcher, described outer tube edge wall is provided with the screens tooth of spiral, and on head capsule, correspondence is provided with screens groove, and after above-mentioned outer tube presses down rotation, its screens tooth is fastened in screens groove to realize the location of outer tube.
In the air blowing syndeton of above-mentioned a kind of dust catcher, the diameter dimension of described mesopore is identical with the outside dimension of air blowing body, and described air blowing body basal diameter is greater than the diameter of mesopore.
Compared with prior art, by pressing down, outer tube is instantaneous to be gone in outer tube by the wind that loose wind passage distributes this device, and it is very convenient to change, and this apparatus structure is simple, can save production cost.
Accompanying drawing explanation
Fig. 1 is installation site of the present utility model schematic diagram.
Fig. 2 is structural representation of the present utility model.
In figure, 1, head capsule; 2, loose air port; 3, screens groove; 4, air blowing body; 5, outer tube; 6, screens tooth; 7, loose wind passage; 8, pore is connected; 9, diaphragm seal; 10, air intake passage; 11, air chamber; 12, back-moving spring; 13, air blowing body bottom surface; 14, insufflation channel.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As illustrated in fig. 1 and 2, the air blowing syndeton of this dust catcher comprises the air chamber 11 be located in dust catcher head capsule 1, described air chamber about 11 has air intake passage 10 and loose wind passage 7 respectively, loose wind passage 7 is communicated with loose air port 2, be provided with an insufflation channel 14 above air chamber 11, and be provided with sealing together 9 insufflation channel 14 is sealed.The center of described diaphragm seal 9 is provided with mesopore, the tubular air blowing body 4 of a back cover is arranged with in mesopore, the external diameter of air blowing body 4 is equal with median pore diameter, the diameter of air blowing body bottom surface 13 is greater than the diameter of mesopore, therefore air blowing body 4 can slide up and down along mesopore, is upwards limited in again on diaphragm seal 9.Be provided with back-moving spring 12 in air chamber 11, the two ends of back-moving spring 12 connect bottom surface and the air blowing body bottom surface 13 of air chamber 11 respectively, and under the effect of back-moving spring 12, described air blowing body bottom surface 13 is pressed on diaphragm seal 9.The lower end sidewall of described air blowing body 4 is provided with and connects pore 8, and when air blowing body 4 presses down, described company's pore 8 is pushed in air chamber 11, and the limit wall of air blowing body 4 then blocks the loose wind passage 7 of air chamber 11.
As shown in Figure 1, head capsule 1 is connected with an outer tube 5, outer tube 5 limit wall is provided with the screens tooth 6 of spiral, and on head capsule 1, correspondence is provided with screens groove 3, and after above-mentioned outer tube 5 presses down rotation, its screens tooth 6 is fastened in screens groove 3 to realize the location of outer tube 5.Simultaneously after outer tube 5 is fixing, air blowing body 4 continues air-supply.
