Fig. 1 (a) is a perspective view showing a first embodiment of the air filter cleaning device of the present invention, and fig. 1 (b) is a partially enlarged perspective view of fig. 1 (a). As shown in fig. 1, an air filter cleaning device 10 according to a first embodiment includes: a rotary brush 2 for cleaning the air filter 1; a box body 3 provided with a rotating brush 2; a pinion (pinion)4 as a propulsion mechanism provided on the case 3; a rack 5 as a support portion that supports the pinion gear 4; and a base member 6.
The pinion gear 4 is fixed to a rotary shaft 8a, the rotary shaft 8a is connected to the motor 7, and when the rotary shaft 8a is rotated by the forward and reverse rotation of the motor 7, the pinion gear 4 is engaged with the rack 5 and is rotated. Further, the gear 9 fixed to the rotary shaft 8a meshes with the gear 11 fixed to the rotary shaft 8b of the rotary brush 2, and the rotary brush 2 is rotated forward and backward by the forward and backward rotation of the motor 7.
Therefore, when the motor 7 rotates forward and backward, the housing 3 provided with the rotating brush 2 can be reciprocated in the longitudinal direction of the rack 5 while rotating the rotating brush 2 forward and backward. The air filter 1 is provided on the base member 6 in the direction in which the case 3 reciprocates.
The base member 6 is provided with a guide portion 12 provided in a direction in which the rotary brush 2 reciprocates. The case 3 is provided with a guide bush 13, and the guide bush 13 is engaged with the guide portion 12 of the base member 6 and slides with respect to the guide portion 12. Further, by engaging the guide portion 12 with the guide bush 13, the movement of the housing 3 in the direction perpendicular to the direction in which the rotary brush 2 reciprocates is restricted. Here, preferable materials of the guide bush 13 include steel-deprived (duragon) resin, polyacetal resin, metal, and the like.
Further, the guide portion 12 in the first embodiment is formed in a rail shape on both sides of the long hole 14 by the long hole 14 formed in the base member 6 in the longitudinal direction of the rack 5.
Fig. 2 (a) is a cross-sectional view showing a first embodiment of the air filter cleaning device of the present invention. According to the air filter cleaning device 10 of the first embodiment, the guide portions 12 formed on both sides of the elongated hole are engaged with the guide bush 13, so that the movement of the housing 3 in the direction perpendicular to the direction in which the brush 2 reciprocates is restricted, and the guide bush 13 has the sliding contact portion 13a having the cross-section コ shape that is in sliding contact with the guide portions 12. The guide bush 13 is fixed to the case 3 by a screw 15. Therefore, the overlapping amount of the brush and the air filter can be adjusted with high accuracy and the assembling time can be shortened as compared with the conventional air filter cleaning device.
Fig. 2 (b) is a cross-sectional view showing a second embodiment of the air filter cleaning device of the present invention. According to the air filter cleaning device 20 of the second embodiment, the guide portion 16 formed in the base member 6 is engaged with the guide bush 13, so that the movement of the housing 3 in the direction perpendicular to the direction in which the brush 2 reciprocates is restricted, and the guide bush 13 has the sliding contact portion 13a having the cross-section コ which is in sliding contact with the guide portion 16. The guide bush 13 is fixed to the case 3 by a screw 15. Therefore, the torsional rigidity of the base member 6 can be improved as compared with the guide portion 12 formed by the elongated hole 14 of the first embodiment.
Fig. 3 (a) is a cross-sectional view showing a third embodiment of the air filter cleaning device of the present invention. According to the air filter cleaning device of the third embodiment, the guide bush 17 which projects the case 3a to the elongated hole 14a side and is rotatable with respect to the projected portion is attached by the screw 18. Therefore, the guide bush 17 serves as a sliding resistance suppressing member for reducing sliding resistance when contacting the guide portion 12 a. Therefore, as compared with the non-rotating guide bush 13 of the first and second embodiments, the sliding resistance can be further reduced, and the movement of the housing can be made smooth, and the generation of the wobble, the noise, and the abrasion can be suppressed, and the housing can be stably moved.
Fig. 3 (b) is a cross-sectional view showing a fourth embodiment of the air filter cleaning device of the present invention. According to the air filter cleaning device of the fourth embodiment, the washer 24, the stationary ring 23, and the washer 25 are fixed to the case 3 in this order by the screws 21, and the rotary ring 22 is rotatably provided outside the stationary ring 23. By engaging the guide portions 12b formed on both sides of the elongated hole with the washer 24, the washer 25, and the rotary ring 22, the movement of the housing 3 in the direction perpendicular to the direction in which the brush reciprocates is restricted. Therefore, the rotating ring 22 rotatably provided outside the washer 24, the washer 25, and the stationary ring 23 serves as a sliding resistance suppressing member for reducing the sliding resistance when contacting the guide portion 12 b. In addition, while friction is present between the guide bush formed of resin or metal and the case formed of resin in the third embodiment, friction is present between the stationary ring formed of metal and the rotating ring formed of metal in the present embodiment, so that the sliding resistance can be further suppressed. In addition, instead of the washer 24, the washer 25, and the fixed ring 23, an integrated guide bush may be provided, and any structure that can reduce sliding resistance when contacting the guide portion 12b, such as a bearing, may be employed instead of the rotating ring 22.
Fig. 4 (a) is a cross-sectional view showing a fifth embodiment of the air filter cleaning device of the present invention. According to the air filter cleaning apparatus of the fifth embodiment, the guide portions 19 formed on both sides of the elongated hole are engaged with the guide bush 13, thereby restricting the movement of the housing 3 in the direction perpendicular to the direction in which the rotary brush 2 reciprocates, and the guide bush 13 has the sliding contact portion having the cross-section コ shape in sliding contact with the guide portions 19 and is fixed to the housing 3 side by the screws 15, which is the same as the configuration of the first embodiment, but is different in that the installation position of the guide portions 19 is not formed in the vicinity of the outer frame to which the air filter 1 is fixed as in the first embodiment. As shown in the fifth embodiment, by forming the guide portion 19 on the side surface of the base member 6, the same effect as the air filter cleaning device shown in the first embodiment can be obtained, and the step of detaching the base member 6 can be omitted when detaching the case 3.
Fig. 4 (b) is a cross-sectional view showing a sixth embodiment of the air filter cleaning device of the present invention. In the air filter cleaning device according to the sixth embodiment, the guide portion 19 is not provided near the outer frame to which the air filter 1 is fixed, as in the first embodiment. In the sixth embodiment, the guide bush 13 is directly fixed to the pinion 4 as the propulsion mechanism. With this configuration, since the brush is not fixed by the case 3, the accuracy of adjusting the overlapping amount of the brush and the air filter can be improved. Further, the sliding resistance suppressing member described in the third embodiment or the fourth embodiment may be applied to the sixth embodiment by replacing the case 3a or the case 3 in the configuration of the third embodiment or the fourth embodiment with the pinion gear 4.
