Abstract
To provide a vacuum cleaner capable of absorbing impact when colliding with a wall, furniture, or the like to prevent the damage of the wall, furniture and the breakage of an outer enclosure. A protector 26 for relieving impact in a collision is formed of a foam resin part 26c formed of foam resin, and an outer skin 26e covering the foam resin part 26c and formed of material different from the foam resin part 26c. Since softness can be uniformly formed over the whole protector 26, impact applied from the outside can be uniformly received and absorbed, and since there is no need to seal air inside, stable impact absorbing capacity can be exhibited over a long period of time. Further, since the foam resin part 26c is covered with the outer skin 26e, cavity parts in the foam resin part 26c are not exposed to the outside. As a result, appearance is fine, external design can be made distinctly conspicuous, and there is no catching on the wall, furniture, or the like because of no cavity part in the surface.
Description
Technical field
The utility model relates to a kind of because electric dust collector more particularly, relates to the guard block of the impact when being used in the electric dust collector absorb collision.
Background technology
Earlier existing electric dust collector is described by Figure 13.Among Figure 13, the shell of electric dust collector main body 1 is made of the dust-collection element lid 5 that lower casing 2, upper casing 3 and switching cover dust-collection element 4 freely.The front portion of flexible pipe (not shown) and lower casing 2 links, and the front portion of lower casing 2 is provided with the air entry 6 that is connected with dust-collection element 4.7 for the parts that formed by soft PVC are guard block, roughly makes the U font, extends to both sides from the front portion of lower casing 2.Figure 13 (b) is the sectional view of guard block 7 and installment state thereof; wherein; the top of guard block 7 is inlaid in the upper end 2a of lower casing 2; the lower end 7b of guard block 7 withstands on the outer wall 2b of lower casing 2, thereby forms a space 7c between the inner surface 7a of the outer wall 2b of lower casing 2 and guard block 7.
Adopt after the above-mentioned structure; even the wall in guard block 7 and room etc. bumps in the dust suction process; the lower end 7b of guard block 7 also can be to sliding downwards along the surface of lower casing 2 shown in Figure 13 (c) like that; and guard block 7 can be to interior curve; to impact and be absorbed; thereby can prevent that not only dust collector host body 1 is impaired, also can prevent simultaneously wall sustain damage (example wherein can be opened flat 8-10193 communique with reference to the Japanese patent gazette spy).
The concrete structure of another kind of existing guard block has been shown among Figure 14.Wherein, be provided with the hollow bulb 8a of sealing in the guard block 8; when the front portion of dust collector host body 1 in the dust suction process or sidepiece and furniture etc. bump, can rely on hollow bulb 8a to absorb impact (example wherein can be opened flat 4-122325 communique with reference to the Japanese patent gazette spy).
Figure 15 is the detailed structure of another existing guard block.Wherein, 9 is the guard block that is formed by soft PVC etc., and this guard block is installed in the top of lower casing 2, and is provided with hollow bulb 9b between guard block 9 and the lower casing 2.In above-mentioned hollow bulb 9b, be provided with and the inner surface formation one of guard block 9 and a plurality of thrust 9a that protrude to the outside wall surface direction of lower casing 2.When impact was added on the guard block 9, bending can take place in these thrusts 9a, to absorb its impact.In addition, the device that also has is foamed material (example wherein can be opened flat 4-218122 communique with reference to the Japanese patent gazette spy) such as urethane fat vacuole foam in above-mentioned hollow bulb 9b filling.
But; in the guard block of the sort of existing electric dust collector shown in Figure 13; because guard block 7 is to be formed by the higher polyvinyl chloride of hardness; so be coupled with when impacting on the guard block 7; though can resemble Figure 13 (c) by absorbing impact to interior curve; but, exist amount of bow and can not fully guarantee, impact the problem that can not be absorbed fully because space 7c's is big or small limited.Space 7c is increased, and nature can improve the impact absorption ability, but so, and guard block 7 will become and bloat very big shape to the outside, produce dust collector host body 1 and will become big problem.
