Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are merely for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.
The first embodiment is as follows:
referring to fig. 1-3, a dustproof computer case comprises a case body 1, wherein two opposite side walls of the case body 1 are respectively provided with a through hole 2 and a circular groove 4, an axial flow fan 3 is installed in the through hole 2, and a rubber rotating shaft 5 is rotatably connected in the circular groove 4.
The louvre 41 has all been seted up to two relative inner walls of circular slot 4, and a plurality of conducting rods 6 of equidistant fixedly connected with of the lateral wall of rubber pivot 5, rubber pivot 5 can insulate a plurality of conducting rods 6 and separate to the conducting rod 6 that the assurance is in rubber pivot 5 top is kept apart with the ground, and can take place to respond to and have electrified.
The lateral wall of box 1 is seted up with the inside communicating bar groove 7 of circular slot 4, installs the electrification device that makes conducting rod 6 take place static in the bar groove 7, fixedly connected with conducting block 11 on the inner wall of circular slot 4, and conducting block 11 is located the below of rubber pivot 5.
The electrification device comprises a piezoelectric ceramic piece 10 fixedly connected to the inner wall of the strip-shaped groove 7, a magnetic sliding block 8 is connected to the strip-shaped groove 7 in a sliding mode, the sliding block 8 is fixedly connected with the piezoelectric ceramic piece 10 through a connecting rod 9, and one blade of the axial flow fan 3 is made of an iron material.
It should be noted that, as shown in fig. 2, the bar-shaped groove 7 and the piezoelectric ceramic plate 10 are disposed above the right side of the circular groove 4, and the heat dissipation holes 41 are distributed only on the side of the conductive rod 6 close to the piezoelectric ceramic plate 10, as shown in fig. 3. The design can ensure that: on one hand, the airflow entering the box body 1 can be fully contacted with the conductive rod 6, and the conductive rod 6 can adsorb dust in the air more thoroughly; on the other hand, after the conducting rod 6 absorbs enough dust, the rubber rotating shaft 5 can be pushed to rotate clockwise under the action of gravity.
In this embodiment, when the computer is in operation, the axial flow fan 3 can be operated, and air flows through the box 1 in the direction of the arrow in fig. 1, so as to dissipate heat in the box 1.
In this process, when the blades of the axial flow fan 3 rotate, the iron blades of the axial flow fan 3 will be continuously close to and away from the magnetic slider 8. As shown in fig. 1, when the iron blade is close to the slider 8, the slider 8 can be attracted to move leftwards and the piezoelectric ceramic plate 10 is pulled to bulge outwards, and when the iron blade is far from the slider 8, the piezoelectric ceramic plate 10 is restored under the action of the self elasticity of the piezoelectric ceramic plate 10 and the slider 8 is pulled to move rightwards and reset. So can be at axial fan 3's the rotation in-process make piezoceramics piece 10 take place the vibration of making a round trip about, under the effect of piezoelectricity effect, its both ends will gather out a large amount of static charges when piezoceramics piece 10 vibrates, be in rubber pivot 5 top simultaneously, and the conducting rod 6 that is close to piezoceramics piece 10 will take place the induction electrification, conducting rod 6 will also take the static, the air that gets into in box 1 by louvre 41 will be sweeped over conducting rod 6, the electrostatic absorption on the conducting rod 6 that the dust in the air received can be adsorbed on conducting rod 6. Therefore, air entering the box body 1 can be purified, dust in the air is prevented from entering the box body 1 and being attached to the computer electronic device, and adverse effects of the dust on the host device are avoided.
When the conducting rod 6 close to the piezoelectric ceramic piece 10 adsorbs a sufficient amount of dust, the mass of the conducting rod 6 is increased, as shown in fig. 2, the rubber rotating shaft 5 is pushed to rotate clockwise, the conducting rod 6 adsorbing the dust vertically moves downwards and contacts with the conducting block 11, and the static electricity on the conducting rod 6 is transferred to the ground through the conducting block 11 and the box body 1. The dust on the conducting rod 6 can fall off by self weight after losing the electrostatic force effect. And after the rubber rotating shaft 5 rotates, the other conducting rod 6 can be rotated to be opposite to the piezoelectric ceramic piece 10, induction electrification can be carried out again to adsorb dust, and therefore the device can continuously and circularly purify air entering the box body 1.
Example two:
referring to fig. 4-5, different from the first embodiment, a sliding groove 13 is formed on the inner wall of the circular groove 4, an iron scraping bar 15 is slidably connected in the sliding groove 13, soft bristles are arranged on the side wall of the scraping bar 15, an electromagnet 14 is fixedly connected to the inner top of the sliding groove 13, a spiral coil 12 is embedded on the inner wall of the strip-shaped groove 7, and the spiral coil 12 is coupled in a power supply circuit of the electromagnet 14.
It should be noted that the spiral coil 12 is only distributed in a part of the moving stroke of the slider 8, so that the slider 8 can be ensured to move back and forth continuously into and out of the spiral coil 12. On the one hand, a varying magnetic flux is generated in the helical coil 12 to generate an induced current, and on the other hand, the generated current is an intermittent pulse current.
In the embodiment, the sliding block 8 will continuously enter and exit the spiral coil 12 during the process of moving back and forth in the strip-shaped groove 7, so that the magnetic flux in the spiral coil 12 generates intermittent change, and thus induction current can be intermittently generated and the electromagnet 14 can be intermittently electrified.
Every time the electromagnet 14 is electrified, magnetic force can be generated, the iron scraping strip 15 is attracted to move upwards, after the electromagnet 14 is powered off, the magnetic force disappears, the scraping strip 15 moves downwards by means of the electromagnet, the vertical downward conducting rod 6 can be continuously cleaned when the scraping strip 15 moves upwards and downwards, and accordingly dust adsorbed on the conducting rod 6 is quickly scraped off, and the dust cleaning efficiency of the device is improved.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered as the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
