The chimney is used to discharge flue gases and other emissions from the fireplace, furnace, and low or high combustion chamber burners to the outside environment. Installing a chimney hood on the outside of the chimney can prevent water from entering the chimney during rainy days.

[0003] Most of the existing chimney covers are fixed to the outside of the chimney by multiple sets of bolts. Although this installation method is firm, it is troublesome to install and disassemble. In addition, the bolts are prone to rust due to humid air on rainy days, which in turn affects the stability of the connection. In addition, the existing chimney covers have relatively simple functions and only have a simple rainproof function. Therefore, a chimney cover that is easy to install is proposed to solve the above problems. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] See also Figure 1-3 In this embodiment, a chimney cover that is easy to install includes a chimney body 1 and a chimney cover body 2. Two sets of mounting structures 3 are arranged between the chimney body 1 and the chimney cover body 2. A filtering rainproof component 4 is arranged in the chimney cover body 2.

[0021] The mounting structure 3 comprises a through opening 301, which is provided on the side wall of the chimney cover body 2, a movable plate 302 is movably mounted inside the through opening 301, a push block 303 and a resistance block 304 are respectively fixedly mounted on the left and right sides of the movable plate 302, a return spring 305 is sleeved on the surface of the resistance block 304, a fixed block 306 is fixedly mounted on the inner wall of the chimney cover body 1, a rotating shaft 307 is rotatably mounted on the front side of the fixed block 306, a torsion spring 308 is arranged inside the chimney cover body 2, a rotating rod 309 is fixedly mounted on the surface of the rotating shaft 307, a triangular clamp 310 is fixedly mounted on the left side of the top of the rotating rod 309, and an L-shaped rod 311 is fixedly mounted on the left side of the chimney body 1;

[0022] The filtering rainproof component 4 includes three filter plates 401, which are fixedly installed between the left and right side walls of the chimney cover body 2. Two connecting columns 402 are fixedly installed on the top of the chimney cover body 2, and rain shields 403 are fixedly installed on the top of the two connecting columns 402.

[0023] like Figure 2 and Figure 3 As shown, by setting the push block 303 to be a rubber material, since rubber itself has a large friction coefficient, it is convenient for people to use, and triangular slots are opened inside the two L-shaped rods 311, and the two triangular slots are respectively matched with two triangular clamping heads 310, so that the triangular clamping heads 310 can be firmly inserted into the triangular slots, thereby ensuring the connection stability between the chimney cover body 2 and the chimney body 1.

[0024] like Figure 2 and Figure 3 As shown, the reset spring 305 is fixedly installed between the right side of the movable plate 302 and the inner wall of the through-opening 301, and the reset spring 305 is sleeved on the surface of the abutment block 304. Through this arrangement, the reset effect of the reset spring 305 can drive the abutment block 304 to release the limit on the rotating rod 309 after the abutment block 304 loses pressure, so that the triangular clamp 310 can be inserted into the triangular clamping slot.

[0025] like Figure 2 and Figure 3 One end of the torsion spring 308 is fixedly connected to the inner wall of the chimney cover body 2, and the other end of the torsion spring 308 is fixedly connected to the outer surface of the rotating rod 309. Through the reset effect of the torsion spring 308, the auxiliary triangular clamp 310 is inserted into the triangular clamping groove opened by the L-shaped rod 311.

[0026] like Figure 2 and Figure 3 As shown, the width of the chimney cover body 2 is greater than the width of the chimney body 1 , thereby ensuring that the chimney cover body 2 can cover the chimney body 1 .

[0027] like Figure 2 As shown, filter nets are arranged in the middle of the three filter plates 401 , through which large particle pollutants in the smoke can be filtered, thereby reducing the pollution of the smoke to the air. The rain shield 403 is trapezoidal, thereby preventing rainwater from accumulating on the top of the rain shield 403 .

[0028] When implementing, follow these steps:

[0029] 1) First, the push block 303 is pushed inward, and the push block 303 drives the moving plate 302 and the abutment block 304 to press the rotating rod 309, so that the rotating rod 309 rotates;

[0030] 2) Then, the chimney cover body 2 is put onto the outside of the chimney body 1 and moved to the designated position;

[0031] 3) Release the push block 303 again, and due to the reset action of the reset spring 305, the resistance block 304 moves outward through the moving plate 302;

[0032] 4) Finally, due to the reset effect of the torsion spring 308, the rotating rod 309 drives the triangular clamp 310 to be inserted into the triangular clamping groove of the L-shaped rod 311 for fixation, thereby completing the connection and fixation between the chimney cover body 2 and the chimney body 1.

[0033] In summary, the chimney cover which is easy to install is provided with the installation structure 3. When the chimney cover body 2 needs to be installed, the push block 303 is first pressed inwardly, and the push block 303 drives the resistance block 304 to press the rotating rod 309 through the movable plate 302, so that the rotating rod 309 rotates, so that the torsion spring 308 is squeezed, and then the chimney cover body 2 is put on the outside of the chimney body 1. After moving to a certain position, the push block 303 is released, and due to the reset effect of the reset spring 305, the resistance block 304 moves outward through the movable plate 302. The torsion spring 308 is movable, and due to the reset effect of the torsion spring 308, the rotating rod 309 drives the triangular clamp head 310 to be inserted into the triangular clamping groove of the L-shaped rod 311 for fixation, thereby completing the connection and fixation of the chimney cover body 2 and the chimney body 1. Through the above-mentioned arrangement, the installation process of the chimney cover body 2 is simplified, and a stable connection can be made without the use of bolts, thereby improving work efficiency. In addition, by arranging the filtering rainproof component 4, not only can the smoke discharged from the chimney body 1 be filtered to reduce its harm to the air, but it can also play a role in rain protection, which is practical.
