[0022] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0023] Example 1

[0024] like Figures 1-5 As shown, this embodiment provides an energy-saving device for a blower, including two blower bodies 1, a dust cover 3, and an air outlet pipe 2.

[0025] The air outlet of the blower body 1 is set upward. The air outlets of the two blower bodies 1 are connected to the air outlet pipe 2. The air outlet channel 22 is located inside the air outlet pipe 2. Each side of the air outlet channel 22 has an air outlet. The air outlet is flared to increase the air volume.

[0026] A self-opening and closing rotating plate 21 is provided at the air outlet of the blower body 1 and the air outlet end. The self-opening and closing rotating plate 21 is used to connect or block the air outlet end of the blower body and the air outlet channel 22. Specifically, the self-opening and closing rotating plate 21 includes a plate body, and the two sides of one end of the plate body are rotatably connected to the two side walls of the air outlet pipe 2. The movable end of the plate body faces the air outlet of the air outlet channel 22.

[0027] Preferably, the plate is an arc-shaped plate with the circle of the plate facing the inside of the blower body 1. When the blower body 1 near the air outlet of the air outlet channel 22 starts blowing air, the inner arc surface of the plate is subjected to force and flips upward, closing the connection between the air outlet channel 22 and the other blower body 1. When the other blower body 1 blows air, the outer arc surface of the plate is subjected to force, tightly closing the air outlet of the blower body 1. No matter which blower body 1 is blowing air, there will be no air leakage.

[0028] To further improve the sealing performance, sealing gaskets are provided around the air outlet end of the blower body 1 with the plate installed. The shape of the sealing gaskets corresponds to the plate. When the plate and the air outlet end of the blower body 1 are closed, the sealing performance is better. Similarly, sealing gaskets can be provided on the closed-loop surface of the air outlet channel 22 that contacts the plate. This is not shown in the attached drawings of this solution.

[0029] The dust cover 3 is detachably connected to the air inlet end of the blower body 1, covering the air inlet end of the blower. Specifically, the dust cover 3 includes a cover body 31 and a vent sleeve 32. The cover body 31 has multiple air inlet strip holes 34 formed on its circumferential and end faces. The vent sleeve 32 is detachably installed on the outer circumferential surface of the cover body 31. The cover body 31 is a cylindrical shell with an opening on one end face. A connecting protrusion ring 33 is formed on the outer circumferential surface of the end of the cover body 31 with the opening. The cover body 31 is connected by screws passing through the connecting protrusion ring 33 and extending into the side wall of the blower body 1. The vent sleeve 32 is a cloth bag, which is connected to the connecting protrusion ring 33 by a rubber strip. The purpose of setting up the cover body 31 and the cloth bag is to prevent dust from entering the blower body 1. When dust enters the blower body 1, it will increase its weight and damage the bearings, leading to increased energy consumption. Therefore, this solution avoids this situation by setting up the dust cover 3.

[0030] Example 2

[0031] like Figures 1-4 As shown, the difference between this embodiment and embodiment 1 is that the dust cover 3 includes a cover body 31 and a breathable membrane. The cover body 31 has multiple air inlet strip holes 34 formed on its peripheral surface and end face. Multiple breathable membranes cover multiple air inlet strip holes 34 respectively. The breathable membrane is attached to the surface of the cover body 31 by setting an adhesive strip on its outer edge. When it is necessary to clean the dust on the breathable membrane, it can be directly peeled off.

[0032] Both embodiments of this solution connect the air outlet ends of two blower bodies 1 to the air outlet channel 22. A self-opening rotating plate 21 is installed at the air outlet end of the blower body 1 closest to the air outlet channel 22. When the blower body 1 closest to the air outlet channel 22 blows air, the self-opening rotating plate 21 is opened to allow air to escape. When the blower body 1 furthest from the air outlet channel 22 blows air, the self-opening rotating plate 21 is blown by the wind to close its air outlet end. With two blower bodies 1, when the energy consumption of one blower body 1 increases, it indicates the need for maintenance. At this time, the other blower can be turned on for operation. This allows for maintenance and dust removal of the blower body 1 without affecting airflow, ensuring that the blower body 1 always operates in a high-efficiency mode, resulting in better energy saving.
