[0027] Example:

[0028] See also Figure 1-7 , the utility model provides the following technical solutions: a new type of storm machine, including a shell 1, a motor 2, a guide pipe and a wind nozzle 7;

[0029] The outer shell 1 is composed of two shells, front and rear. A turbofan 3 is installed on the right side of the inner cavity of the outer shell 1, and a motor 2 is installed on the right side of the turbofan 3 for driving. Rubber shock-absorbing pads are used on the mounting bracket of the motor 2 to reduce the vibration generated by the motor 2 during operation from being transmitted to the outer shell, further reducing the overall noise level.

[0030] An air collecting pipe 4 is installed on the left side of the turbofan 3. A tapered conical pipe is provided at the left end of the air collecting pipe 4. A flow guide pipe is installed on the left side of the air collecting pipe 4, and the air collecting pipe 4 is inserted into the flow guide pipe.

[0031] The air guide tube includes two replaceable parts: a first air guide tube 5 and a second air guide tube 6. The first air guide tube 5 and the second air guide tube 6 adopt a modular design for easy replacement. A nozzle 7 is installed on the left side of the housing 1, and the nozzle 7 is connected to the air guide tube to the right. The motor 2 drives the turbofan 3 to rotate to generate airflow, which is compressed and transmitted in the air collection tube 4. The airflow is then transported to the left through the air guide tube and then blown outward through the nozzle 7. The second air guide tube 6 adopts a tapered cylinder that gradually tapers to the left.

[0032] The right end of the air nozzle 7 is provided with an air collecting tube 8, which consists of an outer tube 8-1 and an inner tube 8-2. The outer tube 8-1 is sleeved on the outer side of the inner tube 8-2, and a mounting groove is opened between the outer tube 8-1 and the inner tube 8-2. The outer wall of the inner tube 8-2 is sleeved with an adjusting ring 8-4, and the adjusting ring 8-4 is located in the mounting groove.

[0033] Wind-gathering blades 8-3 are evenly mounted on the side walls of the inner cavity of the inner cylinder 8-2. The wind-gathering blades 8-3 are arc-shaped blades and extend obliquely toward the middle of the inner cylinder 8-2. Adjustment slots 8-5 are equidistantly provided on the right side of the outer wall of the inner cylinder 8-2. The wind-gathering blades 8-3 are composed of fixed blades and adjustable blades. A telescopic blade 8-7 is mounted between the fixed blades and the adjustable blades. One end of the telescopic blade 8-7 is fixedly mounted on the fixed blade, while the other end of the telescopic blade 8-7 is movably inserted into the inner cavity of the adjustable blade. The length of the wind-gathering blade 8-3 is changed by moving the adjustable blade, thereby adjusting the wind-gathering effect.

[0034] An outwardly extending extension plate is provided on one side of the adjusting blade, and the extension plate is inserted into the adjusting slot 8-5. At the same time, the other end of the extension plate is fixed to the inner side of the adjusting ring 8-4. The adjusting ring 8-4 slides on the outer wall of the inner tube 8-2, thereby driving the adjusting blade to complete the telescopic movement; the adjusting ring 8-4 is symmetrically embedded with a locking bolt 8-6. The locking bolt 8-6 is a flat-bottomed bolt. When the locking bolt 8-6 is downward, it rubs against the outer wall of the inner tube 8-2 to fix the adjusting ring 8-4.

[0035] The surface of the locking bolt 8-6 after installation is parallel to the surface of the adjustment ring 8-4, so that the locking bolt 8-6 does not contact the outer tube 8-1; a through slot 8-8 is formed on the outer side of the outer tube 8-1, and the through slot 8-8 is located directly above the locking bolt 8-6 for use with a screwdriver; a threaded ring is provided on the right side of the air nozzle 7, and an external thread is provided on the left side of the air collecting tube 8. The air collecting tube 8 is installed in the air nozzle 7 by screwing the external thread and the threaded ring together, and the air collecting tube 8 only occupies half the horizontal width of the threaded ring of the air nozzle 7;

[0036] A battery box 9 is provided at the bottom of the handle of the housing 1, and the battery box 9 provides power to the device;

[0037] The housing 1 is constructed from a blend of high-strength engineering plastic and aluminum alloy. Special sealing strips are used at the joints between the front and rear shells to ensure a tight seal within the internal structure, preventing dust, moisture, and other impurities from entering and impacting the device. The engineering plastic portion provides excellent insulation and a certain degree of impact resistance, while the aluminum alloy portion enhances the overall structural strength and stability, enabling it to withstand collisions and vibrations in industrial environments.

[0038] Heat dissipation fins are designed on the surface of the housing 1, especially in the area near the motor 2 and turbofan 3. These heat dissipation fins are made of aluminum alloy and connected to the housing body through a precision casting process. The shape of the heat dissipation fins has been optimized and streamlined to increase the contact area between the air and the fins, thereby improving heat dissipation efficiency. At the same time, ventilation holes are rationally arranged on the housing. The ventilation holes are designed to be circular or elliptical, and the edges of the holes are chamfered to reduce air flow resistance, so that the heat generated inside can be dissipated in time, ensuring long-term stable operation of the equipment.

[0039] The WS-3 blades are swept back to more effectively capture and accelerate air. Special coatings, such as ceramic coatings, reduce friction between the air and the blades, minimizing energy loss and improving the efficiency of the turbofan. The WS-3 hub is precision-machined from high-strength aluminum alloy to ensure a secure connection with the blades and excellent dynamic balance, minimizing vibration and noise during operation.

[0040] The conical tube portion of the air collecting tube 4 adopts a gradual contraction design, which allows the airflow to accelerate smoothly in the conical tube and avoid turbulence. The inner wall of the air collecting tube 4 is made of smooth stainless steel and is polished to minimize the friction between the airflow and the tube wall. The connection between the air collecting tube 4, the turbofan 3 and the guide tube uses a rubber sealing ring with good sealing performance to ensure that the airflow does not leak and improve the overall air pressure transmission efficiency. The material of the air nozzle 7 is selected from high-temperature resistant and high-strength engineering plastics, and the inner wall of the air nozzle 7 adopts a streamlined design to reduce airflow resistance.

[0041] The arc design of the wind-gathering blades 8-3 has been optimized, and its curvature matches the diameter of the inner tube 8-2, which can better guide the airflow to converge toward the center of the inner tube. The wind-gathering blades 8-3 are made of aluminum or copper fins, and their telescopic length can be adjusted between 0 and 5 cm. The wind-gathering effect can be controlled by moving the adjustment ring 8-4.

[0042] The main function of the arc design of the wind-collecting blades 8-3 is to concentrate the airflow delivered from the guide pipe and use the vortex effect generated by the arc blades to increase the wind speed; it can increase the speed of the airflow at the outlet of the wind nozzle 7. When the flow rate remains unchanged, the area of ​​the airflow channel becomes smaller, and the airflow speed will increase accordingly, thereby producing a stronger blowing effect.

For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention; therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive.
