[0019] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present invention. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0020] Embodiment: A filter device for dust removal, such as Figure 1-Figure 4As shown, it includes a mounting plate 1, a grille plate 2, a filter screen 3, an extension frame 4, a support rod 6 and an isolation shell 10. The mounting plate 1 is a U-shaped structure. The grille plate 2 is fixedly connected inside the mounting plate 1. The filter screen 3 is sleeved on the mounting plate 1. The inner bottom of the filter screen 3 contacts the bottom of the grille plate 2. The top of the mounting plate 1 is fixedly connected to the bottom of the extension frame 4. The extension frame 4 is a U-shaped frame. The extension frame 4 is an inverted L-shaped structure that is symmetrical on the front and back sides and extends to the left and right directions. The lower parts of the front and back sides of the extension frame 4 are symmetrically provided with guide grooves 5. A support rod 6 is slidably connected between the two guide grooves 5 on the same side. The support rod 6 is a U-shaped rod. The two support rods 6 are symmetrically distributed on the left and right sides. The inner bottom of the support rod 6 contacts the bottom of the filter screen 3. The front and back sides of the extension frame 4 are symmetrically fixedly connected with an isolation shell 10. The isolation shell 10 is made of rubber, and the isolation shell 10 is closed to the guide groove 5 on the inner side of the extension frame 4.
[0021] like Figure 4 and Figure 5 As shown, a hook 11 is also included. The hook 11 is symmetrically fixedly connected to the middle part of the front side of the extension frame 4. The side of the hooks 11 away from each other is a clamping part, and the side of the clamping part of the hook 11 away from each other is an inclined surface. The hook 11 is made of plastic material. The two hooks 11 are respectively located on the side where the two guide grooves 5 are close to each other. The inclined surface of the clamping part of the hook 11 contacts the upper part of the support rod 6, and the clamping part of the hook 11 is clamped with the upper part of the support rod 6.
[0022] When it is necessary to use this device, the device can be installed at the air inlet of the corresponding device through the extension frame 4, and normal dust removal and filtering can be carried out; during use, the locking portion of the hook 11 contacts and locks with the upper portion of the support rod 6, thereby limiting the support rod 6, so that the inner bottoms of the two support rods 6 are respectively in contact with the two sides of the bottom of the filter 3, which can support the bottom of the filter 3 and make the inner bottom of the filter 3 more closely fit with the bottom of the grille plate 2, so that the filter 3 is evenly stressed, ensuring the use effect, good filtering effect, extending the service life, and improving the safety of use; the setting of the isolation shell 10 can close the guide groove 5 on the inner side of the extension frame 4, thereby ensuring the sealing of the extension frame 4, and can effectively prevent the gas from entering the device without being filtered.
[0023] When the filter screen 3 needs to be replaced, the engaging portion of the hook 11 is pulled downward to disengage the engaging portion of the hook 11 from the upper portion of the support rod 6, thereby releasing the limit on the support rod 6, and then the support rod 6 is pulled to slide along the guide groove 5 to the side away from the hook 11 until the inner bottom of the support rod 6 is disengaged from the bottom of the filter screen 3, thereby releasing the support for the filter screen 3, and then the old filter screen 3 can be removed from the mounting plate 1, and then the new filter screen 3 can be sleeved on the mounting plate 1, and then the support rod 6 is pulled to slide along the guide groove 5 to the side close to the hook 11, so that the inner bottom of the support rod 6 is in contact with the bottom of the filter screen 3, thereby releasing the support for the filter screen 3. The bottom of the filter screen 3 is in contact with the support rod 6, and the support rod 6 moves to make the bottom of the filter screen 3 fit more closely with the bottom of the grille plate 2. When the upper part of the support rod 6 contacts the inclined surface of the engaging part of the hook 11, the engaging part of the hook 11 will be squeezed to move downward, and the support rod 6 continues to move. When the upper part of the support rod 6 is out of contact with the inclined surface of the engaging part of the hook 11, under the elastic action of the hook 11 itself, the engaging part of the hook 11 will move upward and reset and contact and engage with the upper part of the support rod 6, thereby re-limiting the support rod 6, and then supporting the bottom of the filter screen 3 for subsequent normal use.
[0024] like Figure 4 and Figure 6 As shown, it also includes a U-shaped frame 8 and a brush 9. The upper parts of the front and rear sides of the extension frame 4 are symmetrically provided with slide grooves 7. The U-shaped frame 8 is slidably connected between the two slide grooves 7. The part where the left part of the U-shaped frame 8 is connected to the slide groove 7 is in the shape of a round rod. The U-shaped frame 8 can rotate around the inner side of the slide groove 7. The size of the U-shaped frame 8 is larger than the size of the support rod 6. The support rod 6 can slide through the inside of the U-shaped frame 8. A brush 9 is fixedly connected to the right side of the U-shaped frame 8, and the left side of the brush 9 contacts the bottom of the filter 3.
[0025] like Figure 6 As shown, it also includes a magnet 12. The upper right side of the extension frame 4 is symmetrically fixedly connected with the magnet 12, and the front and back sides of the U-shaped frame 8 are symmetrically fixedly connected with the magnet 12. The extension frame 4 and the U-shaped frame 8 are attracted by the corresponding magnets 12.
[0026] When the filter 3 needs to be cleaned, the U-shaped frame 8 is pulled to the right, so that the U-shaped frame 8 drives its upper part to slide to the right along the slide groove 7, so that the magnet 12 of the extension frame 4 is out of contact with the magnet 12 of the U-shaped frame 8, thereby releasing the limit of the U-shaped frame 8, and then the U-shaped frame 8 is rotated 90 degrees clockwise, so that the brush 9 is perpendicular to the bottom of the filter 3, and the left side of the brush 9 is in the same plane as the bottom of the filter 3, and then the U-shaped frame 8 is pulled to drive its upper part to slide to the left along the slide groove 7, and the dust on the filter 3 can be scraped off by the contact between the left side of the brush 9 and the bottom of the filter 3 until the left part of the U-shaped frame 8 is The U-shaped frame 8 is then pushed back to the left to return to its original position, and the brush 9 is then pushed back to the right to return to its original position.
[0027] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
