Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically a fan used in garment steamers and ironing machines. Background Technology

[0002] The fan on a garment steamer or iron is like the heart of the device. It generates a strong airflow through a high-speed rotating impeller, providing stable and efficient airflow support for the ironing system. It is the core power source for achieving fast ironing and delicate care.

[0003] Currently, most ironing machines and garment steamers on the market use high-speed axial flow fans due to their small size. The blade shape of these fans results in weak suction, which means they cannot fully adhere to the clothes when ironing. While turbine fans have strong suction, their manufacturing cost is too high. Because there is moisture inside the ironing machine and the high-speed motors on the market are open, moisture can cause the motor bearings or metal parts to oxidize and stick together, leading to bearing failure or the motor fan blades getting stuck, causing the machine to stop working or burn out. Utility Model Content

[0004] The purpose of this invention is to provide a fan specifically designed for garment steamers and ironing machines, in order to solve the problem of low suction power of high-speed fans with axial flow blades mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fan specifically designed for garment steamers and ironing machines, comprising: The fan shroud has a centrifugal impeller located in the center of its interior. A shaft core runs through the center of the impeller. A nut is connected to the outer wall of the shaft core near the impeller. A flat washer is placed between the nut and the impeller. A support washer is placed on the side of the impeller away from the flat washer. A bearing is connected to the outer wall of the shaft core near the center. A stator assembly is located around the outer periphery of the shaft core away from the nut. An air duct is located inside one side of the fan shroud. An insulating sleeve is placed at the end of the air duct away from the fan shroud. A terminal block is connected to the center of the insulating sleeve. A lead wire is connected to one end of the terminal block.

[0006] Preferably, the main housing is provided on the side of the hood closest to the air duct.

[0007] Preferably, the shroud is fixedly connected to the main housing, and the air duct is located inside the main housing.

[0008] Preferably, the centrifugal impeller is fixedly connected to the shaft core by a nut, and the shaft core is fixedly connected to the inner wall of the bearing.

[0009] Preferably, the outer wall of the bearing is fixedly connected to the air duct, the stator assembly is fixedly connected to the air duct, and the stator assembly is fixedly connected to the insulating sleeve.

[0010] Preferably, the insulating sleeve is fixedly connected to the main housing, and the terminal block is fixedly connected to the insulating sleeve.

[0011] Preferably, the lead wire is fixedly connected to the terminal block, and the nut is threadedly connected to one end of the shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model fan achieves strong suction by using a small air duct and adding a centrifugal impeller and fan cover at the air inlet, thus effectively adsorbing clothes.

[0013] This utility model fan adds an insulating sleeve to the periphery of the stator end, which, together with the air duct and terminal block, completely covers the entire stator, resulting in no negative pressure in the motor cavity. This prevents airflow or wind from entering the motor, thus preventing water vapor from entering the motor and avoiding motor burnout or bearing damage and shutdown.

[0014] The novel fan features salt spray treatment in its ductwork to prevent the motor from seizing up and becoming unusable due to oxidation, adhesion, and corrosion caused by prolonged use in a humid environment. Attached Figure Description

A nut 10 is connected to the outer wall of the shaft core 05 near the impeller 02. Tightening the nut 10 at one end of the shaft core 05 causes it to press against the outer surface of a flat washer 11, thus fixing the position of the centrifugal impeller 02. A flat washer 11 is placed between the nut 10 and the impeller 02. A support washer 12 is placed on the side of the impeller 02 away from the flat washer 11. A bearing 04 is connected to the outer wall of the shaft core 05 near the center. The bearing 04 uses rolling friction instead of sliding friction to support the shaft core 05, making the shaft core 05 rotate more smoothly, with less effort, and more durable. The shaft core 05 is further away from the flat washer 11. A stator assembly 06 is provided on the outer periphery of one end of the nut 10. An air duct 03 is provided inside one side of the fan cover 01. Through a small air duct 03, a centrifugal impeller 02 and a fan cover 01 are added to the air inlet end to achieve a large suction force, thereby effectively adsorbing clothes. An insulating sleeve 07 is provided at the end of the air duct 03 away from the fan cover 01. The insulating sleeve 07, together with the air duct 03 and the terminal block 08, completely covers the entire stator, so that there is no negative pressure in the motor cavity, thereby preventing airflow or wind from entering the motor. A terminal block 08 is connected in the middle of the insulating sleeve 07. A lead wire 09 is connected to one end of the terminal block 08. After the lead wire 09 is installed on the terminal block 08, power can be transmitted through the lead wire 09.

[0020] Furthermore, the main housing is provided on the side of the hood 01 near the air duct 03. Through a small air duct 03, a centrifugal impeller 02 and the hood 01 are added to the air inlet to achieve a large suction force, thereby effectively adsorbing the clothes.

[0022] Furthermore, the centrifugal impeller 02 is fixedly connected to the shaft core 05 via the nut 10. After tightening the nut 10 at one end of the shaft core 05, it presses against the outer surface of the flat washer 11, which can fix the position of the centrifugal impeller 02. The shaft core 05 is fixedly connected to the inner wall of the bearing 04. The bearing 04 uses rolling friction instead of sliding friction to support the shaft core 05, making the shaft core 05 rotate more smoothly, with less effort, and more durable.

[0023] Furthermore, the outer wall of the bearing 04 is fixedly connected to the air duct 03, the stator assembly 06 is fixedly connected to the air duct 03, the stator assembly 06 is fixedly connected to the insulating sleeve 07, and the insulating sleeve 07, together with the air duct 03 and the terminal block 08, completely covers the entire stator, so that there is no negative pressure in the motor cavity, thereby preventing airflow or wind from entering the motor.

[0024] Furthermore, the insulating sleeve 07 is fixedly connected to the main housing. The insulating sleeve 07, together with the air duct 03 and the terminal block 08, completely covers the entire stator, so that there is no negative pressure in the motor cavity, thereby preventing airflow or wind from entering the motor. The terminal block 08 is fixedly connected to the insulating sleeve 07 to ensure the stability of the terminal block 08 position.

[0025] Furthermore, the lead wire 09 is fixedly connected to the terminal block 08. After the lead wire 09 is installed on the terminal block 08, power can be transmitted through the lead wire 09. The nut 10 is threadedly connected to one end of the shaft core 05. After the nut 10 is tightened at one end of the shaft core 05, it presses against the outer surface of the flat washer 11, which can fix the position of the centrifugal impeller 02.

[0026] Working principle: When in use, an insulating sleeve 07 is added first, which, together with the air duct 03 and the wiring board 08, completely covers the entire stator. Salt spray treatment is performed on the air duct 03. After startup, there is no negative pressure inside the cavity, and airflow or wind does not enter the motor, achieving strong suction and effectively adsorbing clothing. The above is the complete working principle of this utility model.
