Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of an embodiment of an electrically controlled switch dust collector provided in the present invention; fig. 2 is a schematic installation diagram of an embodiment of the electrically controlled switch provided in the present invention.
The electric control switch dust removing device of the sewing machine mainly comprises a controller shell 1 and an electric control switch 2, wherein a first cavity 11 for placing a motor and a hand wheel is arranged in the controller shell 1, the electric control switch 2 is installed on the side wall of the controller shell 1, and an air outlet 3 for guiding wind generated by rotation of the hand wheel out of the controller shell 1 to the electric control switch 2 is arranged on the side wall.
When the sewing machine is used, the motor drives the hand wheel to rotate, and wind generated when the hand wheel rotates is blown out from the air outlet 3 to blow away lint, dust and the like accumulated and about to be accumulated on the electric control switch 2, so that the effect of removing the dust is achieved, and the dust, the lint and the like can be effectively prevented from entering the electric control switch 2; in addition, when the air is blown outwards through the air outlet 3, the heat inside the controller shell 1 can be taken out, and the temperature inside the electric control device is favorably reduced.
Further, a second cavity 12 for mounting a control component is generally arranged in the controller housing 1, the second cavity 12 is located below the first cavity 11, a heat sink 4 is arranged between the first cavity 11 and the second cavity 12, the heat sink 4 is used for dissipating heat of the high-heat control component, and heat dissipating strips are generally distributed on the surface of the heat sink 4; due to structural limitation, the electronic control switch 2 is usually installed on the outer wall of the second cavity 12, in order to achieve the purpose of automatic dust removal, the air outlet 3 may also be installed on the outer wall of the second cavity 12, and meanwhile, when the heat sink 4 is installed, a gap may be left between the heat sink 4 and the controller housing 1 as an air inlet, of course, the heat sink 4 with a hollowed gap may also be selected, or a plurality of holes may be additionally installed on the heat sink 4 as the air inlet according to the air volume condition actually required by the power switch dust removal, which is also within the protection scope of the present invention.
When the hand wheel rotates, wind blowing towards the motor and the radiating fins 4 is generated, the wind enters the second cavity 12 from the air inlet and then blows out from the air outlet 3 to remove dust on the surface of the electric control switch 2, and in the blowing process, heat generated by the control part in the second cavity 12 can be taken out of the controller shell 1, so that the temperature inside the electric control switch can be reduced.
On the basis of the above embodiments, since dust generally accumulates on the upper plane of the electronic control switch 2, the air outlet 3 is preferably arranged above the electronic control switch 2, and the air generated by rotating the hand wheel is blown to the place where dust is easily accumulated on the electronic control switch 2 by the air outlet 3, so that the dust cleaning and preventing effect is better.
Certainly, the side wall of the controller housing 1 may also be provided with a plurality of air outlets 3, and the air outlets 3 are distributed around the electric control switch 2, which is also within the protection scope of the present invention.
Specifically, the structure of the air outlet 3 is various, and specifically, the structure may be a plurality of holes or other forms, which is not specifically limited in the present application; preferably, the outlet 3 is a transversely extending elongated hole.
On the basis of each embodiment, in order to achieve a better dustproof effect, the side wall of the controller housing 1 may be provided with an inward concave groove 5, and the electronic control switch 2 is installed in the groove 5, wherein the inward concave depth of the groove 5 is preferably not less than the height of the electronic control switch 2, so that the electronic control switch 2 can be completely embedded in the groove 5, and in addition, the groove 5 is preferably square because the electronic control switch 2 is generally square.
Furthermore, the electric control switch 2 is installed on the bottom surface of the groove 5, the upper side surface of the groove 5 is preferably an inclined surface with an outer end inclined upwards, and the air outlet 3 is arranged on the inclined surface, so that air can be blown out towards the electric control switch 2 after being guided by the air outlet 3, and the dust blowing effect is better.
It should be noted that, in order not to affect the storage space of the circuit board components inside the controller housing 1, the size of the groove 5 on the controller housing cannot be too large to prevent the internal components from interfering with the controller housing 1, but the too small concave range may cause the human hand to be unable to press, and finally cause the difficulty in pressing, so that in the limited concave range, the inclined plane processing may be performed on the concave area, and the side surfaces of the groove 5 are preferably inclined planes, that is, the bottom surface of the groove 5 is in transition connection with the plane of the controller housing 1 through the inclined plane.
On the basis of the foregoing specific embodiments, the dust removing device of the electronic control switch 2 provided by the present invention specifically includes a bottom plate 21 fixed on the controller housing 1 and a rocker 22 embedded on the bottom plate 21, the rocker 22 can swing up and down on the bottom plate 21, when one end of the rocker 22 is embedded in the bottom plate 21, the other end is externally disposed on the bottom plate 21, when the rocker 22 swings, the end of the rocker 22 can be turned into the bottom plate 21 from the outside of the bottom plate 21, and can also be turned out of the bottom plate 21 from the inside of the bottom plate 21, and the states of the rocker 22 tilting to both sides respectively represent that the power is turned on and the power is turned off.
Preferably, the rocker 22 is vertically disposed, the rocker 22 has an upper end and a lower end, when the upper end surface of the rocker 22 (the upward-facing plane of the upper end of the rocker 22) is built in the bottom plate 21, the electronic control switch 2 is preferably in the off state, and when the upper end surface of the rocker 22 is externally disposed, the electronic control switch 2 is in the on state; like this when the up end of wane 22 is external, the power is opened, and the motor drives the hand wheel and rotates, can utilize the hand wheel to rotate the wind that produces and remove dust to the up end of wane 22, when the power disconnection, though can't realize automatic dust removal, nevertheless because the up end of wane 22 is internal, consequently the dust can not pile up the up end at wane 22 yet.
Of course, the specific mounting manner of the rocker 22 is not limited thereto, and the rocker 22 may be disposed laterally, and also fall within the protection scope of the present invention.
In conclusion, the dust removing device for the electric control switch 2 provided by the invention has the advantages that the wind generated by the rotation of the handle wheel blows the place where dust is easily accumulated on the electric control switch 2, the effect of automatically removing the dust is achieved, and the existing heat dissipation and exhaust system can be directly used for removing the dust only by slightly changing the existing sewing machine, so the implementation mode is simple, and the cost is low.
