Detailed Description
As shown in fig. 1 and fig. 2, a filter screen cleaning device of a fresh air machine comprises a filter screen support 1, a filter screen 2, a rubber roller 3 and a driving screw 4, wherein the filter screen support 1 is vertically installed in front of a fresh air outlet of the fresh air machine, the filter screen 2, the rubber roller 3 and the driving screw 4 are all installed on the filter screen support 1, and the filter screen support 1 is preferably installed in the fresh air machine in a drawing mode, so that the filter screen is convenient to install and maintain. The rubber roller 3 is abutted to the surface of the filter screen 2 in the horizontal direction, the rubber roller 3 can be a light plastic roller, an adhesive layer is covered on the outer circumferential wall of the rubber roller 3, the adhesive layer can be an adhesive directly coated on the rubber roller or a dust-sticking film stuck on the rubber roller, a plurality of layers of dust-sticking films can be stuck on the rubber roller 3, the outer layer of dust-sticking film is torn off after the dust-sticking effect is lost, the second layer of dust-sticking film is directly used, and the use is more convenient. Coaxially install a supporting shaft 5 in the rubber roll 3, the rubber roll 3 can rotate for supporting shaft 5, the right-hand member of supporting shaft 5 stretches out and is fixed in on the removal seat 6 after the rubber roll 3, remove seat 6 and drive lead screw 4's threaded rod 7 threaded connection, drive lead screw 4 installs upright on filter screen support 1, drive lead screw 4's driving motor 16 can drive threaded rod 7 and rotate, pivoted threaded rod 7 drives and removes seat 6 and reciprocate, it reciprocates to remove seat 6 drive rubber roll 3, roll along the surface of filter screen 2 when the rubber roll 3 reciprocates, glue the dust on the filter screen 2 and remove totally.
As shown in fig. 3 and 4, the rubber roller 3 is a hollow roller with an air cavity inside, the outer circumferential wall of the rubber roller 3 is provided with a plurality of air vents 8, and the side wall of the rubber roller 3 is provided with a circular air outlet 11; the device also comprises an air pipe 9, and the two ends of the air pipe 9 are respectively connected with an air outlet 11 and a negative pressure generator. The negative pressure generator draws air to the rubber roller 3 through the air pipe 9, so that when the rubber roller 3 moves up and down and rolls, dust on the filter screen 2 can be adsorbed, and the dust enters the rubber roller 3 through the ventilation hole 8, and the cleaning efficiency is further improved. The power of the negative pressure generator can be adjusted, so that the dust can be sucked into the rubber roller 3 by the negative pressure. A filter (not shown in the figure) can be installed between the air pipe 9 and the negative pressure generator, the filter is used for filtering dust sucked out from the rubber roller 3 by the air pipe 9 and preventing the dust from entering the negative pressure generator, and the type of the filter is adaptively selected according to the size and concentration of the dust in the use environment.
The tuber pipe 9 is the hose, and the one end fixedly connected with of tuber pipe 9 and the metal joint 10 that the air outlet 11 matches, metal joint 10 insert in the air outlet 11 to metal joint 10 is connected for the contact with air outlet 11, and the junction of metal joint 10 and air outlet 11 has glossy outer wall promptly, and metal joint 10 can be for air outlet 11 free rotation, consequently when rubber roll 3 rotated, tuber pipe 9 can not follow the rubber roll 3 and rotate and appear winding, torsional deformation phenomenon. The tip of metal joint 10 is stretched into behind the rubber roll 3 by air outlet 11 and is connected a spacing dryer 12, and spacing dryer 12 is including the spacing portion 13 that is equipped with the internal thread wall, and the tip of metal joint 10 is equipped with the external screw thread structure, and this tip and spacing portion 13 threaded connection restrict metal joint 10 and outwards break away from air outlet 11.
One end of the metal joint 10, which is positioned outside the rubber roller 3, is in threaded connection with a limiting ring 15, the limiting ring 15 and the limiting air duct 12 limit the metal joint 10 in the air outlet 11 from the outer side and the inner side of the rubber roller 3 respectively, and the metal joint 10 is guaranteed to be stably installed in the air outlet 11.
The limiting air duct 12 further comprises a trumpet-shaped air inducing portion 14, the air inducing portion 14 and the limiting portion 13 are coaxial and integrally formed, and the inner diameter of one end, far away from the limiting portion 13, of the air inducing portion 14 is larger than that of the limiting portion 13. The air inducing part 14 can effectively extract air in the rubber roller 3, so that negative pressure is formed in the rubber roller 3.
The plurality of vent holes 8 are arranged in a row of vent hole groups along the axial direction of the rubber roller 3, the rubber roller 3 is provided with the plurality of rows of vent hole groups, and the vent holes in two adjacent rows of vent hole groups are arranged in a staggered manner. When the rubber roller 3 rolls up and down along the filter screen 2, the ventilation holes 8 which are staggered in the axial direction can eliminate the dust sticking dead zone and the dust collection dead zone.
The working process of the device is as follows: an air pipe 9 is arranged on the rubber roller 3, the filter screen 2, the rubber roller 3 and the driving screw rod 4 are respectively arranged on the filter screen bracket 1, and the driving motor 16 is connected with an external power supply. The new fan during operation need not clean the filter screen under the normal condition, and rubber roll 3 is located the downside of filter screen 2 this moment, does not influence the normal work of filter screen 2. When the filter screen needs to be cleaned, the driving motor 16 is started, the driving screw rod 4 drives the rubber roller 3 to move upwards, the rubber roller 3 rolls along the filter screen 2 simultaneously, and dust on the filter screen 2 is adhered and removed. If more dust exists, the negative pressure generating device can be started simultaneously, and partial dust on the filter screen 2 is sucked through the air pipe 9 and the vent holes 8. After the dust-sticking film on the rubber roller 3 is used for a plurality of times, the dust-sticking effect is gradually lost, the filter screen support 1 can be integrally drawn out from the fresh air machine, the dust-sticking film on the outer layer of the rubber roller 3 is removed, the dust-sticking film on the second layer is used, or the dust-sticking film is attached again.
Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
