[0003] In existing technologies, different types of fans are required for different situations. For example, vacuum cleaners are needed for dust removal, and there are differences between long-distance and short-distance dust removal; air dryers are needed for drying; and cooling fans are needed for heat dissipation. Existing fans have limited functionality and cannot meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to solve the aforementioned technical problems existing in the prior art and to provide an engineering-grade household fan. By installing a motor inside the casing, the motor drives the impeller to rotate, allowing air to enter through the inlet and exit through the dust outlet. A fan shroud is detachably connected to the air inlet of the casing. By selecting different styles of fan shrouds, the fan can achieve both long-distance and short-distance dust collection. A filter bag is detachably connected to the filter bag, which collects the sucked-in dust. When drying and heat dissipation are required, the fan shroud and filter bag can be used directly. The design is ingenious, the operation is convenient, and the functions are diverse, meeting people's usage needs.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] This engineering-grade household dust collector includes: a motor for driving a fan wheel; a housing containing both the motor and the fan wheel, with an air inlet and a dust outlet; a detachable hood connected to the air inlet; and a detachable filter bag connected to the dust outlet. This invention utilizes a motor within the housing to drive the fan wheel, allowing air to enter through the inlet and exit through the dust outlet. The hood is detachably connected to the air inlet, and different styles can be selected to achieve both long-distance and short-distance dust collection. A detachable filter bag collects the collected dust. For drying and heat dissipation, the hood and filter bag can be used directly. The ingenious design, convenient operation, and diverse functions meet various user needs.

[0007] Furthermore, the housing includes a left fan housing, a right fan housing, and a front fan housing. The right fan housing and the left fan housing are connected to form a motor mounting housing. The motor mounting housing has an internal motor mounting cavity, in which the motor is fixedly connected. The front fan housing is fixedly connected to the motor mounting housing. The left fan housing and the right fan housing are spliced ​​and fixed together to form the motor mounting housing. The motor is installed in the motor mounting cavity within the motor mounting housing, and the front fan housing is fixed to the spliced ​​motor mounting housing for secure installation.

[0008] Furthermore, a cavity one is provided on one side of the motor mounting housing, which is connected to the motor mounting cavity. A corresponding cavity two is provided on the fan front housing. After the fan front housing and motor mounting housing are fixedly connected, cavity one and cavity two connect to form a rotor mounting cavity, which is used to install the rotor. The air inlet is located on the fan front housing and is connected to the rotor mounting cavity. After the motor mounting housing is assembled, cavity one is formed on one side, and cavity two is provided on the fan front housing. After the fan front housing is fixedly connected, cavity one and cavity two are joined to form a rotor mounting cavity for installing the rotor. After the motor controls the rotor to run, air enters from the air inlet, passes through the rotor mounting cavity, and is discharged from the dust outlet.

[0009] Furthermore, the right casing of the fan has a semi-circular interface one, and the front casing of the fan has a corresponding semi-circular interface two. When the front casing of the fan is fixedly connected to the top of the motor mounting housing, semi-circular interface one and semi-circular interface two are joined together to form a dust outlet. After the front casing of the fan is installed, semi-circular interface one and semi-circular interface two are joined together to form a dust outlet. Depending on the situation, a filter bag can be detachably connected. When vacuuming, the filter bag is connected to the dust outlet; when cooling or ventilating, the filter bag can be removed.

[0010] Furthermore, the motor is connected to a capacitor, a power cord, and a speed control switch. The speed control switch is used to adjust the speed of the impeller, thereby adjusting the airflow.

[0011] Furthermore, the shroud and the housing are connected by a connecting assembly, which includes an air inlet flange, a shroud fixing plate, and spring clips. The air inlet flange is fixedly connected to the front housing of the fan corresponding to the air inlet. The shroud fixing plate is fixedly connected to the air inlet flange. Limit blocks are fixedly connected to both sides of the shroud fixing plate. The shroud is equipped with corresponding spring clips. The spring clips clamp the limit blocks, thus connecting the shroud to the shroud fixing plate. An air inlet filter is provided between the shroud and the shroud fixing plate. The air inlet flange is used to connect the shroud fixing plate to the front housing of the fan. Limit blocks are provided on both sides of the shroud fixing plate, and spring clips are provided on both sides of the shroud. The spring clips clamp the limit blocks, thus enabling the shroud to be detachably connected to the shroud fixing plate.

[0012] Furthermore, both the fan cover and the bottom of the housing are connected to shock-absorbing pads. These shock-absorbing pads serve to reduce vibration.

[0013] Furthermore, the motor is one of an AC motor, a DC brushless motor, or a variable frequency motor.

[0014] Furthermore, the hood consists of a hood body, one end of which is connected to the housing, and the other end of the hood body protrudes away from the housing and retracts inward to form an interface. This interface is used to connect to the air duct, enabling long-distance dust collection.

[0015] Furthermore, the fan hood adopts a second hood body, one end of which is connected to the shell, and the other end of the second hood body is recessed towards one end of the shell and narrows inward to form an air inlet. The inward narrowing of the air inlet causes outside air to converge towards the air inlet side when it enters, improving the dust collection efficiency.

[0016] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0017] This utility model incorporates a motor within the housing, which drives a fan to rotate, allowing air to enter through the inlet and exit through the outlet. A detachable fan hood is connected to the air inlet of the housing, and by selecting different styles of fan hoods, the fan can achieve both long-distance and short-distance dust collection. A detachable filter bag is connected to the filter bag, which collects the sucked-in dust. When drying and heat dissipation are required, the fan hood and filter bag can be used directly. The ingenious structural design, convenient operation, and diverse functions meet people's usage needs.

[0018] In this invention, the shroud and the housing are connected by a connecting assembly, which includes an air inlet flange, a shroud fixing plate, and spring clips. The air inlet flange is fixedly connected to the front housing of the fan corresponding to the air inlet. The shroud fixing plate is fixedly connected to the air inlet flange. Limiting blocks are fixedly connected to both sides of the shroud fixing plate. The shroud is equipped with corresponding spring clips. The spring clips clamp the limiting blocks, thus connecting the shroud to the shroud fixing plate. An air inlet filter is provided between the shroud and the shroud fixing plate. The air inlet flange is used to connect the shroud fixing plate to the front housing of the fan. Limiting blocks are provided on both sides of the shroud fixing plate, and spring clips are provided on both sides of the shroud. The spring clips clamp the limiting blocks, thus enabling the shroud to be detachably connected to the shroud fixing plate.

[0019] This utility model features a semi-circular interface 1 on the right housing of the central unit and a corresponding semi-circular interface 2 on the front housing of the fan. When the front housing of the fan is fixedly connected to the top of the motor mounting housing, semi-circular interface 1 and semi-circular interface 2 are joined together to form a dust outlet. After the front housing of the fan is installed, semi-circular interface 1 and semi-circular interface 2 are joined together to form a dust outlet. A filter bag can be detachably connected for different situations. When vacuuming, the filter bag is connected to the dust outlet; when cooling or ventilating, the filter bag can be removed.

[0020] The engineering-grade household fan of this utility model has multiple functions.
