Abstract
The utility model discloses electric tool, comprise housing, be positioned at the motor of housing rear end and be positioned at the air outlet that the outer wall of motor position is arranged at housing, after electric tool, end housing is provided with opening, rotate in described opening and seal sleeve is set, described seal sleeve is provided with and air outlet quantity and the position through hole to batch.In use, rotary seal sleeve makes air outlet be in opening to the utility model electric tool, now can proper heat reduction; When being in unused state, rotary seal sleeve makes air outlet be in closed condition, and now dust will be difficult to enter electric tool inside.
Description
Technical field
The utility model relates to field of power tools.
Background technology
Electric tool class, as electric drill, electric hammer and percussion drill etc., its structure comprises housing, is provided with motor in housing rear end inside, and the outer wall that housing is positioned at motor position sets out air port.By air outlet, the electric tool heat that motor produces in running is distributed.
But existing electric tool air outlet cannot be closed, therefore when not using electric tool, dust can enter electric machine casing inside from air outlet, entering causing certain influence the service life of electric tool of dust.
Summary of the invention
For the deficiencies in the prior art, the utility model provides a kind of electric tool, freely can control the open and close of air outlet, prevents entering of when not using dust.
The utility model is achieved through the following technical solutions: electric tool, comprise housing, be positioned at the motor of housing rear end and be positioned at the air outlet that the outer wall of motor position is arranged at housing, after electric tool, end housing is provided with opening, rotate in described opening and seal sleeve is set, described seal sleeve is provided with and air outlet quantity and the position through hole to batch.
In technique scheme, the outer wall of described seal sleeve is provided with the soft glue-line of a circle.
In technique scheme, a protruding block is had in described seal sleeve arranged outside, the chute slided for described protruding block is provided with in described inner walls, when described protruding block leans described chute one end, described air outlet is communicated with the through hole on described seal sleeve, when described protruding block leans the described chute other end, seal sleeve sidewall blocking air outlet.
In technique scheme, a protruding block is had in described seal sleeve arranged outside, the chute slided for described protruding block is provided with in described inner walls, when described protruding block leans described chute one end, described air outlet is communicated with the through hole on described seal sleeve, when described protruding block leans the described chute other end, seal sleeve sidewall blocking air outlet.
The utility model has following beneficial effect: in use, rotary seal sleeve makes air outlet be in opening to the utility model electric tool, now can proper heat reduction; When being in unused state, rotary seal sleeve makes air outlet be in closed condition, and now dust will be difficult to enter electric tool inside.

Fig. 3 is the partial enlarged drawing at B place in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail: see Fig. 1 to Fig. 3, electric tool, comprise housing 12, be positioned at the motor 10 of housing 12 rear end and be positioned at the air outlet 11 that the outer wall of motor position is arranged at housing, after electric tool, end housing 12 is provided with opening, rotate in described opening and seal sleeve 2 is set, described seal sleeve 2 is provided with and air outlet 11 quantity and the position through hole 20 to batch.A protruding block 21 is had in described seal sleeve 2 arranged outside, the chute 13 slided for described protruding block 21 is provided with at described housing 1 inwall, when described protruding block 21 leans described chute 13 one end, described air outlet 11 is communicated with the through hole 20 on described seal sleeve 2, when described protruding block 21 leans described chute 13 other end, seal sleeve 2 sidewall blocking air outlet 11.
Said structure, in use, rotary seal sleeve 2 makes protruding block 21 be in chute 13 right end position (this position can see Fig. 3) to electric tool, and now air outlet is in opening, and thus electric tool can proper heat reduction; When being in unused state, rotary seal sleeve 2 makes protruding block 21 be in chute 13 left position, and now air outlet is in closed condition, and thus dust will be difficult to enter electric tool inside, substantially increase service life.
The outer wall of described seal sleeve 2 is provided with the soft glue-line of a circle.Soft glue-line is mainly used in preventing the vibration passing of the housing when motor runs to seal sleeve 2, causes housing and seal sleeve produce collision thus produce noise.
In this patent, electric tool is electric drill, electric hammer, percussion drill etc.
