Abstract
The utility model provides a blowing dust removing gun which is composed of a gun body, a gas flow diverter, a sealing washer, a tail sleeve, a handle and a button type switch. The utility model is characterized in that the functions of blowing and sucking can be obtained by exchanging the installation direction of the gas flow diverter; because a gun tube adopts the structural form of a Larvor jet tube, the larger blowing force and the larger suction force are generated. The utility model is particularly suitable for blowing the gas, supporting the combustion and cooling and removing various sundries and dust in factories, and can use the compressed air as a power source. The utility model has the advantages of convenient use, beautiful appearance, small volume, light weight and cheap price. The suction force is three to five times bigger than that of the prior art, and the diameter of sucking and removing sundries can reach 20mm.
Description
The utility model relates to a kind of Blowing and sucking dust remover rifle, and this dedusting rifle is made of the body of a gun, seal washer, flow switch, tail cover, handle and push-button switch.
It is HXZ type industry object absorber that the pneumatic Electric Tool Works in Great Wall, Qingdao produces a kind of model, this object absorber mainly is made of housing, nozzle, switch, nozzle is equipped with in suction thing channel center at housing, so just influenced the unimpeded of this passage, on the one hand bigger absorbate is obstructed, can have increased resistance on the other hand again air-flow.Another weak point is that nozzle sprays one thinner air-flow in channel center, and impossible again convergence place that designs at passage of this nozzle, thus can not utilize source of the gas fully, thus influenced the suction material resources of this rifle greatly.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and provides a kind of source of the gas that can make full use of to blow out the high speed swirling eddy in convergence place, cause other end negative pressure maximum, the suction or the power of blowing that forms all reaches a kind of very big raising, combustion-supporting, the cooling of can drying, and can absorb various foreign material, dirt end, chip again, be the Blowing and sucking dust remover rifle of power source with compressed air.
The purpose of this utility model can reach by following measure; Body of a gun endoporus is circular at the muzzle place, inwardly convergence is cone shape gradually, air chamber is a cylindrical hole, and flow switch is installed in air chamber, and endoporus one end of flow switch is cylindrical, the other end is interior big outer little taper shape, have several oblique passages on the sidewall of flow switch, the tail cover connects with the body of a gun by screw thread, flow switch is compressed and seal by seal washer, the endoporus of tail cover is conical, and its tapering is opposite with the tapering of body of a gun endoporus.
The purpose of this utility model can also reach by following measure: body of a gun hole taper α
1Be 6 °～10 °, the tapering α of tail cover endoporus
2Be 6 °～10 °, the tapering α of the bellmouth of flow switch one end
3Be 16 °～20 °, the aperture of the passage on the flow switch sidewall is not more than φ 2.5mm, and hole count is 4～8, at radial equipartition, and the tapering α of centerline hole
4Be 50 °～70 °, centerline hole tilts 24 °～30 ° diametrically simultaneously.
The purpose of this utility model can also be taked following measures: when flow switch is installed, one end of band tapering endoporus is towards the tail cover, this moment, this rifle was a suction condition, and flow switch is turned 180 ° of installations, and making an end of its band tapering endoporus is the air blowing state when muzzle.The material of making the body of a gun, flow switch, tail cover, handle is nonmetal and metal material, and wherein nonmetallic materials have plastics and rubber; Metal material has copper and steel.
The drawing of accompanying drawing is described as follows:
Accompanying drawing 1 is the structure perspective view of the utility model Blowing and sucking dust remover rifle.
The utility model is described in further detail below in conjunction with accompanying drawing: the endoporus of the body of a gun in the accompanying drawing 1 (1) front end is taper, its tapering α
1The best be 6 °～10 °, leave the endoporus air chamber (3) of cylinder at the afterbody of the body of a gun, the cone-shaped inner hole of the body of a gun communicates with air chamber and is in same axis, tail end at air chamber is made internal thread, flow switch (4) is installed in the air chamber (3), a seal washer (2) respectively is equipped with at the two ends of flow switch, the endoporus two ends shape difference of flow switch, wherein an end is a cylindrical bore, the other end is a tapered bore, and on same axis, this axis and the dead in line of body of a gun endoporus, the tapering α of the cone-shaped inner hole of flow switch
3Optimum valuing range be 16 °～20 °, have passage (6) at the sidewall of flow switch, this hole oppose side wall tilts, the inclination alpha of two symmetrical passages (6)
4Be 50 °～70 °, simultaneously centerline hole tilts 24 °～30 ° in radial direction, and the diameter of passage is not more than φ 2.5mm, passage be 4～8 radially uniform, the endoporus of tail cover (5) be a taper shape, its tapering α
2Be 16 °～20 °, be connected with the body of a gun, flow switch is fixed in the air chamber (3), make it sealing by seal washer (2) by screw thread.After the body of a gun, flow switch, tail cover were installed, its endoporus was in same axis.Handle (7) can be made one with the body of a gun, also can separately make, and the through hole that connects source of the gas is arranged on handle, and loads onto gas source connector (8) at this nose end, and push-button switch (9) also is housed on handle.Make the material of the body of a gun, flow switch, tail cover and handle and can select nonmetallic materials and metal material for use, nonmetallic materials are meant plastics and rubber, ABS engineering plastics particularly, when inhaling particular matter, when influencing the service life of Blowing and sucking dust remover rifle owing to plastics intensity, can adopt steel and aluminium in the metal material to make, so that increase its service life.
The installation of flow switch in the accompanying drawing 1 (4) is that the end of endoporus of its band tapering is towards the tail cover, at this moment air-flow sprays into its bellmouth inner chamber through the passage (6) of flow switch, since passage be tilt have 4～8 again, so enter the air-flow ejection at a high speed at a certain angle in cone-shaped inner hole chamber, effectively utilized source of the gas, make muzzle end form negative pressure, thereby produce very big suction thing ability.When the installation direction of flow switch is turned 180 °, promptly cone-shaped inner hole is when muzzle, and air-flow enters the bellmouth inner chamber through passage, and same principle makes the tail cover end of rifle form negative pressure, thereby muzzle end is obtained than the big power of blowing more than 2 times of source of the gas throughput.Therefrom change the installation direction of flow switch as can be seen, this dedusting rifle just can be finished and blow, inhales two kinds of functions.The direction of transposing flow switch is very easily, as long as the tail of outwarding winding is extracted out flow switch, reversing 180 ° gets final product.To inhale the thing effect in order further improving in addition, can to install the auxiliary thing instrument of inhaling at the muzzle place additional, as suction pipe, flat suction pipe, band Brush type suction pipe, tail puts installs a reservoir bag, uses, changes all very easily.
The utility model has the following advantages than prior art:
1, can blow combustion-supporting, cooling and blow down the dust do not open wide in hole, the narrow slit has again the function of absorbing various dirt bits, foreign material and transmission powder, granule materials;
2, it is big to blow power, and suction is also big, and suction is at least bigger 3 times than prior art, and absorbing largest object is φ 20mm.
