SUMMARY

[0004] In view of the deficiencies in the prior art, the utility model provides a kind of energy-saving and environment-friendly heating equipment ventilation device.

[0005] In order to realize the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A kind of energy-saving and environment-friendly heating equipment ventilation device, comprising:

[0007] air inlet pipe, corrugated hose and air outlet pipe constituting ventilation channel;

[0009] The rotating filter plate is rotatably connected to the bending part of the baffle filter plate, and is located at one side of the inner side angle of the bending part of the baffle filter plate;

[0010] The L-shaped bending plate is rotatably connected to the free end of the rotating filter plate, and the bending part thereof is always attached to the inner side of the ventilation channel, and the ventilation opening is formed on the bending plate located in front of the air inlet direction;

[0011] When the rotating filter plate is pulled to rotate along the direction from the inner side angle to the outer side angle of the baffle filter plate through the L-shaped bending plate, the rotating filter plate covers the baffle filter plate, and the air passes through the ventilation opening of the L-shaped bending plate and is redirected by the L-shaped bending plate to blow to the side of the baffle filter plate away from the wind.

[0012] Preferably, the included angle between the rotating filter plate and the baffle filter plate is 10 to 20 degrees initially.

[0013] Preferably, when the rotating filter plate and the baffle filter plate maintain the maximum angle, the bending plate located at the rear side of the air inlet direction of the L-shaped bending plate is attached to the side edge of the baffle filter plate.

[0015] Preferably, the rotating filter plate is connected with a pull rod for controlling the movement of the rotating filter plate at the outer corner of the bending part.

[0016] Preferably, the size of the ventilation opening is slightly smaller than the size of the bending plate located at the front side of the air inlet direction of the L-shaped bending plate.

[0017] Compared with the prior art, the beneficial effects of the present application are:

[0018] 1.

[0028] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0029] Example

[0030] like Figures 1-4 As shown, an energy-saving and environmentally friendly ventilation device for heating equipment includes an inlet pipe 11, a corrugated flexible hose 12, and an outlet pipe 13 forming a ventilation channel. It also includes a V-shaped bent filter plate 21, a rotating filter plate 22, and an L-shaped bent plate 23. The inlet pipe 11 of the ventilation channel is the air intake side. The corrugated flexible hose 12 can be extended and retracted to change the orientation of the outlet pipe 13, facilitating practical use. The outlet pipe 13 is used to prevent external dust from entering the ventilation channel. The bent filter plate 21, the rotating filter plate 22, and the L-shaped bent plate 23 are all disposed inside the outlet pipe 13.

[0031] In one embodiment, such as Figures 3-4 As shown, the "V"-shaped bent filter plate 21 is located inside the ventilation channel and is used to prevent dust from entering the ventilation channel. The inner corner of its bent part faces the air inlet direction. The rotating filter plate 22, which is rotatably connected to the bent part of the bent filter plate 21, is located on one side of the inner corner of the bent part of the bent filter plate 21. The L-shaped bent plate 23 is rotatably connected to the free end of the rotating filter plate 22. Its bent part is always in contact with the inside of the ventilation channel. A ventilation opening is opened on the bent plate located on the front side of the air inlet direction. When the rotating filter plate 22 is pulled to rotate along the direction from the inner corner to the outer corner of the bent filter plate 21 by the L-shaped bent plate 23, the rotating filter plate 22 covers the bent filter plate 21. The air passes through the ventilation opening of the L-shaped bent plate 23 and is redirected by the L-shaped bent plate 23 to the leeward side of the bent filter plate 21.

[0032] In the initial state, when hot air is blown into the outlet pipe 13 through the inlet pipe 11 and the corrugated hose 12, the hot air can be blown from the holes of the rotating filter plate 22 and the inlet 231 to the side of the bent filter plate 21 facing the air inlet direction. At this time, the L-shaped bent plate 23 is located on the rear side of the air inlet direction and is attached to the edge of the bent filter plate 21, so that the dust located outside the outlet pipe 13 will not enter the side of the bent filter plate 21 near the inlet pipe 11.

[0033] When dust adheres to the side of the bent filter plate 21 facing the outside of the air outlet pipe 13, the L-shaped bent plate 23 can be pulled by the pull rod 24, the L-shaped bent plate 23 pulls the rotating filter plate 22 to rotate towards the direction close to the bent filter plate 21, and covers the bent filter plate 21 to close the hole of the bent filter plate 21. At this time, the bent plate on the side of the L-shaped bent plate 23 located on the rear side of the air inlet direction is no longer attached to the edge of the bent filter plate 21. At this time, the hot air cannot be blown out from the hole of the bent filter plate 21, but can only pass through the air inlet 231, and the hot air passing through the air inlet 231 is blown out from the gap between the bent plate on the rear side of the air inlet direction of the L-shaped bent plate 23 and the bent filter plate 21, so that the hot air acts on the side of the bent filter plate 21 located on the rear side of the air inlet direction to clean the dust on the bent filter plate 21. The device can change the flow direction of the hot air by moving the rotating filter plate 22 and the L-shaped bent plate 23, and make the changed hot air act on the side of the bent filter plate 21 located on the rear side of the air inlet direction to clean the bent filter plate 21.

[0034] In one embodiment, as shown in Figures 3-4 The initial angle between the rotating filter plate 22 and the bent filter plate 21 is 10 to 20 degrees, so that the air flow can pass through the angle area during ventilation to enhance the ventilation efficiency in the initial state. At the same time, the angle is set to provide space allowance for the subsequent close space formed by the rotating filter plate 22 and the bent filter plate 21 for back blowing and dust cleaning. On the one hand, it ensures the smoothness of the initial ventilation path, and on the other hand, it is also beneficial to gradually cover and guide the air during the subsequent rotating and close process, to realize the smooth transition of the air direction switching and back blowing effect, and to avoid the structure from being stuck or air leakage caused by too large rotating angle.

[0035] In one embodiment, as shown in Figures 3-4 When the rotating filter plate 22 and the bent filter plate 21 maintain the maximum angle, the bent plate on the rear side of the air inlet direction of the L-shaped bent plate 23 is attached to the side edge of the bent filter plate 21. In the maximum open state, the bent plate structure on the rear side of the air inlet direction of the L-shaped bent plate 23 is in the attached state and is embedded on the side edge of the bent filter plate 21, so as to close the path of external air flow entering the filter plate from the leeward surface. This structure can effectively prevent external dust from bypassing the forward filtering structure and directly entering the internal ventilation pipeline, improve the dustproof sealing performance, and ensure that the air flow concentrates on the designed path and forms a directional blowing area during ventilation. When the rotating filter plate 22 is attached to the bent filter plate 21, the bent plate on the rear side of the air inlet direction of the L-shaped bent plate 23 gradually approaches the bent filter plate 21 along the bent part to the end, forming a compression effect of the air pressure channel, which helps to enhance the blowing strength and improve the dust peeling effect.

[0036] In one embodiment, as shown in Figures 3-4As shown, the rotating filter plate 22 is rotatably connected with a pull rod 24 at the outer corner of the bending part of the rotating filter plate 22, the pull rod 24 is hinged at one end to the outer corner of the bending part of the rotating filter plate 22, and the other end is led out to the outside of the ventilation device or a manual pulling control area. The user can directly pull the pull rod 24 to realize the rotating movement of the rotating filter plate 22 from the initial ventilation angle to the lamination state.

[0037] In one embodiment, as shown in Figures 3-4 As shown, the size of the ventilation opening is slightly smaller than the size of the L-shaped bending plate 23 located on the front side of the bending plate in the air inlet direction. By increasing the edge area of the plate body relative to the ventilation hole, the airflow can be effectively guided to pass through the ventilation opening and form a directional flow inside the structure, improve the airflow impact efficiency, improve the anti-dust cleaning ability, and enhance the stability of the ventilation guide.

[0038] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical concept of the present application.
