[0026] The following will be combined with the drawings of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described in this application are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] like Figure 1 The existing air supply device adjusts the size of the vent by moving the blocking plate 03 up and down, cooperating with the guard plates 02 on the front and rear sides of the frame 01. The guard plates and the blocking plate themselves have a certain height; when the height is too small, the adjustment range is limited; when the height is too large, part of the vent 5 will be blocked, and the resistance when air passes through the vent is large. When the vent is fully opened, that is, the blocking plate moves between the front and rear guard plates, at this time, the guard plate will block part of the vent, affecting the passage of air, and at the same time will increase the resistance when air passes through the vent 5, thereby affecting the air volume supplied to the boiler.

[0028] Combine Figures 2 to 7 , further explaining this application, the biomass boiler air supply device includes at least one fan 1, which is used to provide air for the boiler 4; an air volume adjustment mechanism 3 is provided between the fan 1 and the boiler 4. In this embodiment, the air volume adjustment mechanism 3 is provided on the air inlet of the boiler 4, and a telescopic tube 2 is provided between the air volume adjustment mechanism 3 and the fan 1 to prevent the heat of the boiler 4 from affecting the telescopic tube 2.

[0029] It also includes a power device (not shown), which is in transmission connection with the air volume regulating mechanism 3 and is used to drive the air volume regulating mechanism 3 to adjust the air volume supplied to the boiler 4; the air volume supplied to the boiler can be adjusted without manual adjustment.

[0030] Combine Figure 3The air volume adjustment mechanism 3 includes a connecting seat 31 and a driving plate 32, wherein the connecting seat 31 includes a first connecting seat and a second connecting seat, the driving plate is located between the first connecting seat and the second connecting seat, and the first connecting seat and the second connecting seat are detachably connected to facilitate installation. The connecting seat 31 and the driving plate 32 are respectively provided with a vent 5 along the axial direction, and an adjustment component is provided between the driving plate 32 and the connecting seat 31 for covering or opening the vent 5. Specifically, the adjustment component can be provided between the first connecting seat and the driving plate 32 or between the second connecting seat and the driving plate 32; when the vent 5 is fully opened, the adjustment component will not block the vent 5, so as to avoid causing unnecessary resistance and affecting the air volume supplied to the boiler 4.

[0031] Combine Figure 3 and Figure 4 The adjustment assembly includes at least one windshield 34. The connecting seat 31 is provided with at least one sliding slot 311, which is used to guide the movement direction of the windshield. One side of the windshield 34 is provided with a protrusion 342 that slides within the sliding slot 311. The driving plate 32 is provided with at least one limiting slot 321, which is used to limit the range of movement of the windshield 34. The other side of the windshield 34 is provided with a lever 341 that slides within the limiting slot 321 and can limit the movement of the lever. The number of sliding slots 311 and limiting slots 321 is the same as the number of windshields 34.

[0032] Combine Figure 7 In this embodiment, the five windshields 34A, 34B, 34C, 34D, and 34E are used as an example for explanation. The number of the sliding grooves 311 and the number of the limiting grooves 321 are both five, and the windshield 34 can be an equilateral triangle. After closing, the windshield 34 forms a regular pentagonal structure, and the sliding grooves 311A, 311B, 311C, 311D, and 311E on the connecting seat 31 form a similar regular pentagonal structure. Therefore, the protrusions 342 on each of the windshields 34A, 34B, 34C, 34D, and 34E correspond one to one to the sliding grooves 311A, 311B, 311C, 311D, and 311E; when opened, the protrusions 342 move along the sliding grooves 311 to enable the windshield 34 to open or close the vent 5; of course, the windshield 34 may also be in an arc shape or other shapes, and the number of settings may also be increased or decreased accordingly.

[0033] The power device is connected to the air volume adjustment mechanism 3. A toothed disc 33 is provided on the outside of the drive plate 32. A driving gear is provided on the driving end of the power device to mesh with the toothed disc 33. In this embodiment, the power device is a motor; of course, a rack can also be provided to mesh with the toothed disc 33. The movement of the rack drives the toothed disc 33 to move the windshield 34, thereby driving the toothed disc 33 to rotate.

[0034] In the present application, the power device drives the air volume regulating mechanism 3 to adjust the amount of air supplied to the boiler 4; wherein, the opening and closing of the regulating component can open or close the vent 5, thereby controlling the size of the vent 5 to adjust the amount of air or wind speed supplied to the boiler 4; when the vent 5 is fully opened, the wind shield 34 will not block the vent 5, avoiding the wind shield 34 blocking the vent 5 after opening to cause unnecessary resistance, thereby affecting the air volume supplied to the boiler.

[0035] During actual use, the power device drives the gear disc 33 to rotate the driving plate, forcing the lever 341 to move in the limiting slot 321, driving the wind shield 34 to move along the sliding slot, so that each wind shield 34 moves toward the outside of the connecting seat to open the vent, or moves toward the inside of the connecting seat to close the vent; the protrusion 342 moves along the sliding slot 311 to open or close the vent 5, and the lever 341 slides in the limiting slot 321 to control the size of the opening and closing of the vent 5, so as to control the air supply to the boiler.

[0036] In some embodiments, a detection component is further included. The detection component is arranged between the air volume regulating mechanism and the boiler and is used to detect the amount of air supplied to the boiler and the oxygen content in the boiler to ensure that the fuel can be fully burned in the boiler.

[0037] In some embodiments, a controller is further included, which is electrically connected to the detection component and the power device, and controls the power device to drive the air volume regulating mechanism to control the air volume supplied to the boiler by feedback from the detection component.
