Problems solved by technology

But this method also has great disadvantages, because when the diameter of the air cylinder is larger, the speed of the airflow is smaller, which will lead to a decrease in the spray distance and reduce the efficiency of the spray. flexibility, the device appears cumbersome
Considering the flexibility and compactness of the device, it is necessary to reduce the size of the air cylinder. The smaller the diameter of the air cylinder, the higher the air pressure in the air cylinder will cause the return flow of the fan to increase, which will reduce the efficiency of the fan. This is the same as increasing the spray distance and improving the spray efficiency. Efficiency conflicts
Therefore, in order to solve the problem of reducing the power of the motor, increasing the spray distance, and improving the spray efficiency, there are various disadvantages in the method of changing the size of the air cylinder

Embodiment

[0029] Such as figure 1 , 2 As shown in and 3, a discrete air duct of an electric air blower sprayer includes an electric motor 1, an air duct housing 4 and a fan blade 10; the electric motor 1 and the air duct housing 4 are arranged separately, and the motor 1 is connected to the air duct housing 4 through the connecting piece 3, the rotating shaft of the motor 1 is connected to the fan blade 10, and the fan blade 10 is installed inside the air duct housing 4. Through the separate arrangement of the motor and the air duct shell, the effective area of ​​the air duct air inlet is increased, and the space utilization rate and ventilation efficiency of the air duct are improved.

[0030] An air gap of a certain width is provided between the electric motor 1 and the air duct air inlet. This setting improves the flow of air at the air inlet.

[0031] The width of the air gap is adjustable, and the range of the width adjustment is 20 cm to 30 cm.

[0032] A mounting frame is included. Th...

Abstract

The invention discloses a separated air drum of an electric air-assisted spraying machine. The discrete air drum comprises a motor, an air drum shell and fan blades, wherein the motor and the air-drum shell are separately arranged; the motor is connected with the air drum shell by virtue of a connector; and the rotary shaft of the motor is connected with the fan blades which are arranged in the air-drum shell. The separated air drum disclosed by the invention has the advantages that the effective area of the air inlet of the air drum can be enlarged, so that the space utilization ratio and the ventilating efficiency are increased, the spraying distance and the spraying efficiency are increased, and simultaneously, the power of the motor can be reduced.

Description

Technical field [0001] The invention relates to an electric air blower sprayer, in particular to a separate air duct of the electric air blower sprayer. Background technique [0002] Due to its long spray distance and high efficiency, air-driven spray is widely used in plant protection, industrial dust removal, medical and health and other fields. Reducing the power of the motor, increasing the spray distance, and improving the spray efficiency are one of the key problems to be solved by the air blower. [0003] The air duct is an important part of the air blower. The air cylinder of a traditional electric air blower sprayer is composed of a motor and a housing of the air cylinder. The motor is installed inside the air cylinder, the rotating shaft for power output faces the entrance of the air cylinder, and the fan blades are installed on the rotating shaft of the motor. When the motor is working, it drives the fan blades to rotate, and sends the air flow into the air duct and fl...
