The inside of base 110 is provided with the blower fan 112 of blowout air-flow, the dust storage chamber 113 of collection dust and the filtering filtered to air-flow
Device 114.The air-flow of the blowout of blower fan 112 flows through drill bit bore 111, dust storage chamber 113 and filter 114 successively, by filter 114
The position of blower fan 112 is returned to after filtering.In this manner it is possible to the circulation of gas is completed, meanwhile, the dust at drill bit bore 111
Will be collected into dust storage chamber 113.The effect of dedusting is reached.
Specifically, the position on base 110 near blower fan 112 is provided with the air inlet allowed gas into inside base 110
115.Ambient atmosphere can provide gas by air inlet 115 for blower fan 112, make the throughput inside base 110 bigger, drifting dust
Effect is more preferable.
The training wall 116 of guiding air current flow is provided with base 110.Training wall 116 defines the passage of gas flowing, makes
Gas can preferably play the effect of drifting dust.
It is provided with drill bit bore 111 on base 110 to away from the prominent rubber ring 118 in the direction of expansion link 120.The rubber ring
118 presence can make the electric hammer dust blower 100 can preferably recline when in use needs drilling object, prevent dust from arriving
Place's disperse.
Fig. 2 is refer to, expansion link 120 is detachably secured on the support base 130.Base 110 can be adopted with support base 130
With integrated formed structure, so that the air-tightness of the electric hammer dust blower 100 is more preferable.The end of support base 130 is provided with expansion link 120
It is fastened in the buckle 132 on support base 130.By the buckle 132, expansion link 120 can just be detachably secured to support base
On 130.
Please continue to refer to Fig. 1 and Fig. 4, the blower fan 112 of the electric hammer dust blower 100 includes producing the fan 112a of air-flow and driving
The motor 112b that dynamic fan 112a is rotated.There is the motor accommodation space 134 of accommodating motor 112b in support base 130 and housed
The filter accommodation space 136 of filter 114.Motor 112b is arranged in motor accommodation space 134, and fan 112a is arranged at base
In 110, filter 114 is arranged in filter accommodation space 136.
Fig. 1 and Fig. 2 is refer to, the expansion link of the electric hammer dust blower 100 includes guide post 122 and block set 124.Mounting seat
128 are fixed in block set 124, and guide post 122 is fixed on the support base 130 of dust-blowing device.Guide post is provided with gathering sill
121, it is provided with gib block in block set 124.Guide post 122 mutually slides fixation with block set 124 by gathering sill 111 and gib block.Lead
To groove 111 and the presence of gib block the slip relative with block set 124 of guide post 122 can be made without rolling, that is, there was only axial direction
Move forward and backward without the rotational motion around axis.
The scale that hole depth is beaten for measuring the drill bit of electric hammer is additionally provided with guide post 122.Can thus pass through
Guide post 122 is checked relative to the distance that block set 124 is moved to check that drill bit punches the depth in hole.
Elastic component 126 is provided with block set 124.One end of the elastic component 126 is resisted against on guide post 122 and prevents guide post
122 move in block set 124.Elastic component 126 herein is ring spring.So, when using the electric hammer dust blower 100, can
To ensure that what base 110 can be tightly is resisted against on the object for needing drilling.
The power line 123 of motor 112b can reach mounting seat 128 through guide post 122 and block set 124.Mounting seat 128
Power interface is provided with, power interface is realized being electrically connected with power line 123.When so mounting seat 128 is connected with other devices,
Can realize being electrically connected with the lump.
Fig. 3 to Fig. 5 is refer to, the course of work of the electric hammer dust blower 100 is explained below.
Need to be used cooperatively with electric hammer 200 when the electric hammer dust blower 100 is used.The mounting seat 128 of the electric hammer dust blower 100
It is fixed on the fuselage of electric hammer 200, the drill bit 220 of electric hammer 200 passes through drill bit bore 111.Power interface in mounting seat 128 can be with
It is connected with power supply or external power source on electric hammer 200, by the power supply of electric hammer 200 for the electric hammer dust blower 100 provides the energy.When
So, the electric hammer dust blower 100 can also itself integrated promising motor 112b operating the power supply of electric energy is provided.
When electric hammer 200 works, the electric hammer dust blower 100 will start simultaneously at work.Now the drill bit 220 of electric hammer 200 will
Start punching, rubber ring 118 will be resisted against on the object for needing punching, and motor 112b will drive fan 112a to rotate.Fan
The rotation of 112a will produce the air-flow, air-flow drill bit bore 111 will be flowed first under the limitation of training wall 116, such as arrow institute in Fig. 3
The direction for showing.Air-flow can be in the direction of the arrow taken in dust storage chamber 113 dust at drill bit bore 111 to.Then air-flow can reach
At filter 114, according to the direction shown in arrow in Fig. 4.By after the filtration of filter 114, air-flow reaches motor and houses
Space 134 simultaneously returns to fan 112a positions.A circulation is thus completed, and dust is collected.Opened on base 110
If air inlet 115 can ensure the air for having abundance in base 110.
As the drill bit 220 of electric hammer 200 enters the object for needing punching, the guide post 122 of expansion link 120 will be to block set
Motion in 124, the elastic force of elastic component 126 will ensure that the rubber ring 118 on base 110 can be close to the object of needs punching,
Prevent dust from spilling.Meanwhile, guide post 122 will be read relative to the move distance of block set 124 by the scale on guide post 122,
The depth in punched hole can so be grasped.
The electric hammer dust blower 100 collects dust using the method for drifting dust, relative to the position for producing dust, filter
The 114 lower wind directions for being arranged at air-flow, blower fan 112 is arranged at the upwind of air-flow, and so the electric hammer dust blower 100 is to airflow passes
The air-tightness requirement in air channel need not be too high, the manufacturing process of the electric hammer dust blower 100 also require it is not high, manufacturing cost compared with
It is low.In addition, the air-flow that the electric hammer dust blower 100 is produced forms a circulation, i.e. the electric hammer dust blower in the electric hammer dust blower 100
100 carry out dedusting using circulating current, can so reduce gas outflow from the electric hammer dust blower 100, flow out the electric hammer
Therefore the dust of dust blower 100 is also just reduced.Due to the use of circulating current, when the filter 114 of the electric hammer dust blower 100
Filter effect it is bad when, there will not be too many dust leakage and go out the electric hammer dust blower 100.In sum, the electric hammer drifting dust
Device 100 has the sealing requirements to the air channel of airflow passes relatively low, low cost of manufacture, the few advantage of dust leakage.
Embodiment described above only expresses several embodiments of the invention, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the scope of the claims of the present invention can not be interpreted as.It should be pointed out that for one of ordinary skill in the art
For, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to guarantor of the invention
Shield scope.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
