Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As fig. 1, for the utility model discloses a side wall fan, including rectangular inside hollow dustcoat 1, dustcoat 1 internally mounted has fan body 11 (see fig. 3), and the one end of dustcoat 1 is equipped with sealing mechanism 2, and the other end is connected with filter screen 4, and filter screen 4 can block some great impurity in dustcoat 1 outside.

As shown in fig. 1, when the indoor air needs to be exhausted, the sealing mechanism 2 is controlled to be opened, then the fan body 11 (see fig. 3) is started, and the indoor air passes through the filter screen 4, the fan body 11 and the sealing mechanism 2 in sequence and is finally exhausted to the outdoor. When the indoor air exhaust is not needed, the sealing mechanism 2 is controlled to be closed so as to prevent the external smoke and dust from entering the indoor space through the side wall fan.

As shown in fig. 2, an elongated sliding hole 12 is formed in one side surface of the housing 1, the sealing mechanism 2 includes a sealing plate 21 slidably connected to an inner wall of the housing 1, the sealing plate 21 is vertically disposed, and one end of the sealing plate 21 extends out of the housing 1 through the sliding hole 12. The upper and lower end faces of the sealing plate 21 are flush with the upper and lower end faces of the inner wall of the outer cover 1, respectively. The sealing plate 21 is pushed in a direction approaching the housing 1 until the sealing plate 21 abuts against the side wall of the housing 1 away from the sliding hole 12, at which time the sealing plate 21 seals the housing 1.

As shown in fig. 3, the upper and lower ends of the sealing plate 21 are respectively fixed with a slider 22, and the slider 22 is fixed at one end of the sealing plate 21 disposed inside the housing 1. The inner wall of the outer cover 1 is provided with a pair of sliding grooves 23, and the sliding blocks 22 are respectively connected with the sliding grooves 23 in a sliding manner. When the sealing plate 21 is slid, the slider 22 slides along the length direction of the slide groove 23, and the slide groove 23 provides a sliding guide function to the sealing plate 21. When the sealing plate 21 slides to the outside of the housing 1 until the sliding block 22 abuts against one end of the sliding groove 23 near the sliding hole 12 (see fig. 2), the sealing plate 21 slides out of the housing 1 to the maximum extent.

As shown in fig. 3, the sealing plate 21 is connected to a drive mechanism 3 for controlling the sliding of the sealing plate 21. The driving mechanism 3 includes a connecting rod 31 fixedly connected to an end of the sealing plate 21 away from the slider 22, and the connecting rod 31 is fixed to a lower end surface of the sealing plate 21. The lower end of the connecting rod 31 is fixedly connected with a rack 32 arranged in the horizontal direction, the convex teeth of the rack 32 are arranged downwards, a gear 33 is meshed on the rack 32, a driving motor 34 with positive and negative rotation is connected on the gear 33, and the driving motor 34 is installed on the lower end face of the outer cover 1. The drive motor 34 is located at the lower end of the housing 1 to prevent the drive motor 34 from getting wet in rainy weather.

When the sealing plate 21 needs to be moved, the driving motor 34 is started, the driving motor 34 drives the gear 33 to rotate, the gear 33 rotates to drive the rack 32 and the connecting rod 31 to move horizontally, and the connecting rod 31 moves horizontally to drive the sealing plate 21 to reciprocate horizontally.

As shown in fig. 3, a guide bar 35 arranged in a horizontal direction is fixedly connected to an upper end surface of the rack 32, a groove 36 is formed in a bottom surface of the housing 1, and the guide bar 35 is slidably connected to the groove 36. When the rack 32 moves, the guide rod 35 slides along the length direction of the groove 36, and the groove 36 gives the rack 32 a sliding guide function.

As shown in fig. 4, as time goes up, dust and impurities are attached to the filter screen 4, and the filter screen 4 is detachably connected to the housing 1 in order to clean the filter screen 4. The square support ring 41 of circle outside edge fixedly connected with of filter screen 4, the one side that dustcoat 1 was equipped with slide opening 12 is equipped with the mounting hole 13 of rectangular shape, and filter screen 4 alternates inside getting into dustcoat 1 from mounting hole 13. As shown in fig. 1, when the filter screen 4 is installed inside the housing 1, a surface of the support ring 41 adjacent to the mounting hole 13 is flush with an outer side wall of the housing 1 where the mounting hole 13 is provided.

As shown in fig. 4, the upper and lower end surfaces of the support ring 41 are respectively provided with a strip-shaped groove 42, the upper and lower end surfaces of the inner wall of the outer cover 1 are respectively provided with a strip-shaped rod 43, and the strip-shaped groove 42 and the strip-shaped rod 43 are respectively connected in a sliding manner. When the filter screen 4 needs to be detached, the filter screen 4 is pulled from the end of the outer cover 1 provided with the filter screen 4 to the direction of the mounting hole 13, so that the support ring 41 slides along the bar-shaped rod 43 until the filter screen 4 is separated from the outer cover 1 from the mounting hole 13.

As shown in fig. 4, in order to connect the filter screen 4 and the housing 1 more firmly, a locking assembly 5 is provided on the housing 1. Locking subassembly 5 includes and rotates the pin 51 of being connected with dustcoat 1, and pin 51 can paste the lateral wall that attaches dustcoat 1 and be rotary motion, still is connected with the joint pole 52 that the horizontal direction set up on the dustcoat 1, and the vertical upwards bending of one end that the dustcoat 1 was kept away from to joint pole 52 makes and forms the notch between joint pole 52 and the dustcoat 1. As shown in fig. 1, when the stop lever 51 is rotated until the stop lever 51 is snapped into the notch formed by the snap lever 52, the stop lever 51 contacts one surface of the housing 1 and abuts against the support ring 41, and the filter screen 4 is locked inside the housing 1.

The implementation principle of the embodiment is as follows: when the side wall fan needs to be started, the driving motor 34 is started firstly, the driving motor 34 drives the sealing plate 21 to slide until the sliding block 22 props against one end of the sliding groove 23 close to the sliding block, and then the fan body 11 is started to discharge air indoors.

When the side wall fan needs to be shut down, the fan body 11 is shut down firstly, then the driving motor 34 is started, the driving motor 34 drives the sealing plate 21 to slide until the sealing plate 21 abuts against the side wall of the outer cover 1 far away from the sliding hole 12, and at the moment, the outer cover 1 is sealed by the sealing plate 21.

When the filter screen 4 needs to be disassembled for cleaning, the stop lever 51 is rotated until the stop lever 51 is separated from the notch and far away from the support ring 41, and then the filter screen 4 is pulled from the end of the outer cover 1 provided with the filter screen 4 to the direction of the mounting hole 13, so that the support ring 41 slides along the bar-shaped rod 43 until the filter screen 4 is separated from the outer cover 1 from the mounting hole 13.

When the filter screen 4 is cleaned and needs to be installed, one end of the support ring 41 is aligned to the installation hole 13 and the support ring 41 is pushed to enable the strip-shaped groove 42 to be in sliding connection with the strip-shaped rod 43, and when one surface, close to the installation hole 13, of the support ring 41 is flush with the outer side wall, provided with the installation hole 13, of the outer cover 1, the filter screen 4 completely enters the inner portion of the outer cover 1; the filter screen 4 is then installed by rotating the stop lever 51 until the stop lever 51 snaps into the notch formed by the catch lever 52.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
