[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0025] like Figures 1 to 7 As shown, an energy-saving building ventilation and dust removal device provided by an embodiment includes a ventilation pipe with a rectangular cross-section, a fan (not shown) is arranged in the ventilation pipe, the ventilation pipe includes a horizontal section 2 and a vertical section 3 that are connected to each other, a protective net 111 is arranged at one end of the horizontal section 2 away from the vertical section 3, a filter screen 311 is arranged in the vertical section 3, and the fan is arranged between the filter screen 311 and the protective net 111;

[0026] A rectangular installation frame 1 is provided at one end of the horizontal section 2 away from the vertical section 3, and strip-shaped vertical through grooves 15 are provided on both the upper and lower sides of the installation frame 1, and a strip-shaped horizontal through groove 14 is provided on the bottom side of the installation frame 1. A horizontal guide groove 22 is provided on the inner side wall of the horizontal section 2, and the guide groove 22 is aligned with the horizontal through groove 14;

[0027] The outer side of the protection net 111 is sleeved with a protection net frame 1, and the protection net frame 1 is slidably arranged in the vertical through groove 15. The bottom surface of the protection net frame 11 is provided with a protrusion 112, and the protrusion 122 is an arc-shaped protrusion, and there are two protrusions 122, which are respectively arranged at both ends of the bottom surface of the protection net frame 11;

[0028] A horizontal movable plate 21 is slidably arranged in the horizontal through slot 14, and a plurality of grooves 211 are arranged on the upper surface of the movable plate 21. The plurality of grooves 211 are arranged along the extension direction of the horizontal section 2. The grooves 211 are arranged in two rows, respectively arranged on both sides of the top surface of the movable plate 21, so that the two rows of grooves 211 correspond to the positions of the two protrusions 112, and the grooves 211 may be arc-shaped grooves;

[0029] A spring 12 is arranged at the top of the protective net frame 1, and the spring 12 provides a downward force for the protective net frame 1. Specifically, a fixing plate 13 is arranged on the top surface of the horizontal section 2, and the fixing plate 13 covers the vertical through groove 15 on the upper side of the protective net frame 1. The fixing plate 13 is detachably connected to the top surface of the mounting frame 1, and both ends of the spring 12 are fixedly connected to the fixing plate 13 and the top of the protective net frame 11, respectively.

[0030] A socket (not shown) is arranged on the side wall of the vertical section 3 close to the protective net 1 , and a drawer 31 is arranged in the socket. The bottom surface of the drawer 31 is formed by a filter net 311 .

[0031] The drawer 31 is connected to the front end of the movable plate 21 via a handle 4 , and the end of the movable plate 21 away from the protective net 1 is located above the drawer 31 .

[0032] Specifically, Figure 3 and Figure 8 As shown, the opening 23 does not completely cover the bottom surface of the horizontal section 2, and there is a horizontal plate A near the vertical section 3. The lower part of the vertical section 3 has a protrusion toward the horizontal section 2, and the top surface of the protrusion is the horizontal plate B. The horizontal plate B serves as the top plate of the socket. The horizontal plate B and the horizontal plate A are welded to make the position sealed. After the movable plate 21 is fully inserted, its end away from the handle 4 is located above the horizontal plate A.

[0033] A spray dust removal device is set at one end of the vertical section 3 away from the horizontal section 2, that is, the spray dust removal device is connected to the bottom of the vertical section 3. The prior art documents of the spray dust removal device of this application have been disclosed, and the spray dust removal device with the same content as the prior art disclosure can be used in this application.

[0034] When this application is used, Figure 1 In the state shown, the fan provides negative pressure, and the external air enters the horizontal section 2 from the protective net 111, and then the air enters the vertical section 3, and is further filtered by the filter net 31. The air filtered by the filter net 31 enters the spray dust removal equipment for further removal of dust particles.

[0035] When the filter 31 needs to be cleaned, the handle 4 is pulled outward to pull out the drawer 31. During this process, the movable plate 21 also moves outward. At this time, since the spring 12 presses down the protection net frame 11, when the groove 211 passes the protrusion 112, it will drive the protection net frame 11 to vibrate up and down, and the large particles and debris attached to the protection net 111 will be shaken off. The attachments that fall from the inside of the protection net 111 will fall on the top of the movable plate 21. As the movable plate 21 moves outward, the attachments thereon will be blocked by the bottom edge of the mounting frame 1, and since the end of the movable plate 21 close to the vertical section 3 is located above the drawer 31, when the movable plate 21 and the drawer 31 are fully pulled out, the blocked attachments will also fall into the drawer 31, and then the filter 311 can be cleaned.

[0036] Afterwards, the protective net frame 11 is slightly lifted upward, and the movable plate 21 is inserted into the horizontal through groove 14 and the guide groove 22 to continue air purification. At this time, the drawer 31 is also inserted into the vertical section 3.

[0037] If the protection net 111 needs to be replaced, the screws on the fixing plate 13 are removed, and the fixing plate 13 is lifted to pull the protection net 111 out of the installation frame 1 .

[0038] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
