[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0017] Reference Figures 1 to 3 A dust prevention device for building demolition includes an output handle 1, which is integrally formed and fixedly connected to a mounting shell 101. A motor is arranged inside the output handle 1, and the motor is externally connected to a power supply, etc. A reducer is fixedly installed inside the mounting shell 101, and the motor and the reducer are connected to each other. An output end of the reducer is fixedly connected to an output shaft 102, and a blade for cutting is fixedly installed at the end of the output shaft 102. A dust prevention mechanism is connected to the upper part of the output shaft 102.

[0018] Preferably, the dustproof mechanism comprises: a driving bevel gear 103, a driven bevel gear 106, the middle part of the output shaft 102 is integrally formed and fixedly connected with the driving bevel gear 103, the upper part of the driving bevel gear 103 is meshed with the driven bevel gear 106, the middle part of the driven bevel gear 106 is integrally formed and connected with one end of the connecting shaft 105, the middle part of the connecting shaft 105 is rotatably mounted inside the mounting housing 101 through a bearing, and the other end of the connecting shaft 105 is fixedly mounted with a blade 107. When in use, the motor of the output handle 1 is started, and the motor will drive The driven reducer and the output shaft 102 rotate clockwise, and the rotation of the output shaft 102 will drive the active bevel gear 103 to rotate. Because the active bevel gear 103 is meshed with the driven bevel gear 104, the driven bevel gear 104 will also rotate and drive the blade 107 to rotate at the same time. At this time, since the wind direction of the blade 107 is from the Y-shaped chamber 104 to the connecting outlet 108, when the blade 107 blows air into the connecting outlet 108, a negative pressure will be formed in the Y-shaped chamber 104.

[0019] Preferably: a Y-shaped chamber 104 is opened inside the installation shell 101, the interior of the Y-shaped chamber 104 is an inverted Y-shape, and the three ends are connected, and a blade 107 is installed in the middle of the upper end of the Y-shaped chamber 104, and a connecting outlet 108 is provided on the upper part of the Y-shaped chamber 104, and the outlet end of the connecting outlet 108 is connected to an external breathable plastic bag, and the breathable plastic bag can intercept dust inside the bag. When the blade 107 blows air into the connecting outlet 108, a negative pressure will be formed in the Y-shaped chamber 104, thereby driving the cut dust to be attracted and sucking the dust into the connecting outlet 108. Since the outlet end of the connecting outlet 108 is connected to an external breathable plastic bag, the breathable plastic bag can intercept dust inside the bag, so the dust will be stored in the breathable plastic bag to form a dust-proof.

[0020] Preferably, when the active bevel gear 103 rotates clockwise, the meshed driven bevel gear 106 and the blade 107 are driven to rotate, and the wind direction of the blade 107 at this time is to inhale air from the Y-shaped chamber 104 and connect to the outlet 108 to discharge air.

[0021] Working principle: When in use, start the motor of the output handle 1, the motor will drive the reducer and the output shaft 102 to rotate clockwise, and the rotation of the output shaft 102 will drive the active bevel gear 103 to rotate, and because the active bevel gear 103 is engaged with the driven bevel gear 104, the driven bevel gear 104 will also rotate and drive the blade 107 to rotate at the same time. At this time, since the wind direction of the blade 107 is from the Y-shaped chamber 104 to the connecting outlet 108, when the blade 107 blows air into the connecting outlet 108, a negative pressure will be formed in the Y-shaped chamber 104, thereby driving the cut dust to be attracted and the dust will be sucked into the connecting outlet 108. Since the outlet end of the connecting outlet 108 is connected to an external breathable plastic bag, the breathable plastic bag can intercept dust. Inside the bag, the dust will be stored in the breathable plastic bag to form dustproof.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
