Description
Technical field:
The utility model relates to a kind of dust blower.
Background technology:
Along with the lifting of people's modern life level, people require very high to various daily necessitiess, add the use of now a lot of electronic equipments, cleaner can be described as the standing articles for use of family, on market, cleaner is of all kinds, dust blower is the most general, but, dust blower in the market comprises rifle body, handle, air inlet pipe, escape pipe, handle, valve rod, spring, air inlet duct, sealing ring, described handle is arranged on rifle body rear end, described air inlet pipe runs through handle, described escape pipe is arranged on rifle body front end, described handle is arranged on rifle body lower end, described rifle body is connected by described air inlet duct with described handle, in described air inlet duct, be provided with valve rod, described valve rod coordinates with described sealing ring, described handle is connected with valve rod contact, described spring and rifle body top are supported, described valve rod is connected with spring and sealing ring, when hand handle, band ovable valve stem moves up and down and is with dynamic seal ring to move up and down spring position, gas enters air inlet duct, enter again escape pipe, finally reach the dust of removing on object, but, due to moving up and down of sealing ring, easily cause ring wear, distortion, so just make the service life of dust blower short, easily gas leakage, therefore have much room for improvement.
Utility model content:
Goal of the invention of the present utility model is to overcome above-mentioned the deficiencies in the prior art, and the dust blower of a kind of long service life, good airproof performance is provided.
In order to realize foregoing invention object, the utility model has adopted following technical scheme:
A kind of dust blower, comprise rifle body, handle, air inlet pipe, escape pipe, handle, valve rod, spring, air inlet duct, sealing ring, wherein, described handle is arranged on rifle body rear end, described air inlet pipe is arranged in handle, the air inlet of described air inlet pipe exposes to handle, described escape pipe is arranged on rifle body front end, the gas outlet of described escape pipe exposes to rifle body, described air inlet duct is arranged in rifle body, the gas outlet of described air inlet pipe is communicated with by described air inlet duct with the air inlet of described escape pipe, described handle is arranged on the lower end of rifle body, described spring arranges in described air inlet duct, described valve rod is arranged in air inlet duct, described sealing ring is installed in air inlet duct, described handle is connected with described valve rod contact, also comprise pad, described pad is arranged between described spring and described sealing ring, and described pad and described spring are supported, described sealing ring is arranged between the gas outlet of described air inlet pipe and the air inlet of described escape pipe, described valve stem sleeve is located on spring, the middle part of described valve rod concaves and is a recess, described valve rod runs through described pad and sealing ring.
Described escape pipe front end sleeve is provided with rubber cap, and described rubber cap is affixed by injecting glue mode and escape pipe.
The outer end of described valve rod is provided with sealing gasket.
The utility model has the following advantages with respect to prior art tool:
First, between spring and sealing ring, increased pad, avoided spring stress to directly act on sealing ring, sealing ring has been caused to damage, thereby made the longer service life of dust blower.
Secondly, between spring and sealing ring, increase a pad, be also provided with sealing gasket in the outer end of valve rod, make the utility model better tightness.
Finally, the rubber cap in the utility model and escape pipe are affixed by injecting glue mode, thereby avoid rubber cap in use procedure to come off.
Accompanying drawing explanation:
Fig. 1 is the utility model structural representation (in figure, arrow represents the flow direction of gas).
The specific embodiment:
Referring to Fig. 1, a kind of dust blower providing according to the utility model, comprise rifle body 1, handle 10, air inlet pipe 9, escape pipe 8, handle 2, valve rod 3, spring 6, air inlet duct 11, sealing ring 5, wherein, handle 10 is arranged on rifle body 1 rear end, air inlet pipe 9 is arranged in handle 10, the air inlet of air inlet pipe 9 exposes to handle 10, escape pipe 8 is arranged on rifle body 1 front end, the gas outlet of escape pipe 8 exposes to rifle body 1, air inlet duct 11 is arranged in rifle body 1, the gas outlet of air inlet pipe 9 is communicated with by air inlet duct 11 with the air inlet of escape pipe 8, handle 2 is arranged on the lower end of rifle body 1, spring 6 arranges in air inlet duct 11, valve rod 3 is arranged in air inlet duct 11, sealing ring 5 is installed in air inlet duct 11, handle 2 is connected with valve rod 3 contacts, also comprise pad 4, pad 4 is arranged between spring 6 and sealing ring 5, and pad 4 is supported with spring 6, sealing ring 5 is arranged between the gas outlet of air inlet pipe 9 and the air inlet of escape pipe 8, valve rod 3 is set on spring 6, the middle part of valve rod 3 concaves and is a recess, valve rod 3 runs through pad 4 and sealing ring 5, after effectively avoiding spring 6 stressed, directly act on sealing ring, cause the damage of sealing ring, thereby make longer service life of the present utility model.
Operation principle of the present utility model: gas enters rifle body 1 from air inlet pipe 9, when hand handle 2, the stressed motion of the direction to handle 10 of handle 2, band ovable valve stem 3 is to the interior motion of rifle body 1, spring 6 is subject to force compresses, the centre of valve rod 3 is a recess, now gas will enter into air inlet duct 11 upper ends by the space between recess and sealing ring and pad in the middle of valve rod 3, move to escape pipe 8 again, the last rubber cap 7 from escape pipe 8 front ends out, finally reach the dust of removing on object, when hand release handle 2, affected by the tension force of spring 6, spring restores to the original state, direction motion with from ovable valve stem 3 to handle 2, the inner of valve rod 3 will return to the position of the sealing ring 5 setting firmly in air inlet duct 11, finally realize sealing state.
Above-described embodiment is only for illustration of the utility model; and be not limitation of the utility model; the those of ordinary skill in relevant technologies field; in the situation that not departing from spirit and scope of the present utility model; can also make a variety of changes and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
