Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of blow-suction machine equipment, and specifically relates to a blow-suction machine. Background Technology
[0002] A leaf blower is a garden tool used to collect and remove leaves, trash, and other debris. It is widely used in parks, streets, courtyards, and other places. The leaf blower primarily uses strong suction to draw leaves and debris into the machine, ultimately collecting the leaves in a collection bag.
[0003] Modern leaf blowers can perform both blowing and suction operations. When suctioning, the fan's rotation creates airflow that draws leaves and dust from the ground into the suction tube, where it is then processed by the fan and collected in the collection device. In this mode, the blower functions as a vacuum cleaner. When switching to blowing mode, the suction tube is removed from the blower, and the sides of the casing are sealed with protective covers. However, it has been found that the suction tube and protective covers are secured with a single locking clip, which is prone to breakage over time, resulting in a shorter lifespan for the device. Utility Model Content
[0004] The purpose of this invention is to provide a blow-suction machine to solve the problems mentioned in the background art.

The specific embodiments described herein are merely used to explain this utility model and are not intended to limit this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0034] Example:
[0035] like Figures 1-6 As shown, this utility model provides a blower / vacuum cleaner, including a housing 1. A suction tube 2 is detachably connected to the bottom of the housing 1. A flow guide 3 is installed on one side of the suction tube 2, and a blower 4 is connected to one side of the housing 1. In specific use, the blower 4 can be replaced with a dust collection bag according to the usage scenario. A drive unit 5 is provided inside the housing 1, and a locking slot 11 is provided at the bottom of the housing 1. A connecting part 6 is provided on the side of the suction tube 2 away from the flow guide 3, and a connecting part 6 is also provided at the end of the flow guide 3 away from the housing 1. The connecting part 6 is detachably connected to the locking slot 11. During disassembly and assembly, the connection part 6 of the flow guide 3 and the suction tube 2 is installed and fixed through the locking slot 11 at the bottom. This not only ensures high connection stability and ease of disassembly and assembly, but also extends service life. During use, the drive unit 5 located inside the housing 1 operates. When blowing air is required, the suction tube 2 is removed, and the flow guide 3 is closed to seal the housing 1, completing the mode switch, and the blower 4 is used for operation.
[0036] like Figures 2-4As shown, a limit block 12 is provided inside the locking slot 11. The limit block 12 is trapezoidal. The connecting part 6 includes a connecting plate 61, a return spring 62, and a locking block 63. An installation groove 611 is provided in the middle of the connecting plate 61. The locking block 63 is installed inside the installation groove 611. The return spring 62 is installed between the locking block 63 and the connecting plate 61. During installation, the locking block 63 located inside the connecting plate 61 is moved to open and close with the limit block 12. The return spring 62 locks and fixes the locking, and the trapezoidal limit block 12 ensures the stability of the locking. It is also easy to disassemble and has a long service life.
[0037] The locking block 63 includes an L-shaped push plate 631, a first connecting buckle 632, a second connecting buckle 633, and a spring support 634. The L-shaped push plate 631 is horizontally positioned. A set of symmetrically arranged, oppositely positioned first connecting buckles 632 are vertically mounted above the L-shaped push plate 631. The first connecting buckles 632 are located inside the mounting groove 611. A spring support 634 is positioned between the two first connecting buckles 632, and the spring support 634 abuts against the return spring 62. The second connecting buckle 633 is vertically mounted at the bottom of the L-shaped push plate 631. The bottom of the second connecting buckle 633 is triangular and abuts against the limiting block 12. The trapezoidal structure of the limiting block 12 provides higher locking stability and makes it less likely to fall off. The L-shaped push plate 631 is used to adjust the position of the first connecting buckle 632 and the second connecting buckle 633 for easy use. Moreover, the second connecting buckle 633 is not easily deformed during movement and has a long service life. The first connecting buckle 632 can further improve the stability of the L-shaped push plate 631 moving inside the mounting groove 611.

During use, the air deflector 3 rotates via the rotating shaft 31, and the torsion spring 32 can reset the air deflector 3 when it is opened.
[0040] A cover plate 33 is provided on one side of the flow guide 3, and a fan blade 34 is provided inside the flow guide 3. The cover plate 33 protects the fan blade 34 and performs blowing and suction work by rotating the fan blade 34.
[0041] An extension plate 21 is provided on the side of the straw 2 near the flow guide 3. A pressure block 13 that cooperates with the extension plate 21 is provided on the surface of the housing 1. A groove 35 is provided on the surface of the flow guide 3. The groove 35 is located above the pressure block 13. When in use, the extension plate 21 is used to cooperate with the pressure blocks 13 for easy disassembly and assembly. It is also disassembled and connected through the connecting part 6 and the locking slot 11 on the other side. After the flow guide 3 is closed on the surface of the housing 1, the pressure block 13 is located inside the groove 35 to avoid protrusion and deformation.
[0042] The bottom of the extension plate 21 is provided with a U-shaped connecting block 22, and the inside of the housing 1 is provided with an installation block 14. The U-shaped connecting block 22 and the installation block 14 are snapped together. The U-shaped connecting block 22 and the installation block 14 connected together by snapping not only improve the stability of the straw 2 connection, but also facilitate disassembly and assembly.
[0043] In summary, this device features high connection stability, easy assembly and disassembly, and a long service life.
