Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaners, in particular to a noise reduction device for an air outlet of a vacuum cleaner which is convenient for adjusting wind direction. Background Art

[0002] Vacuum cleaners can be divided into vertical, horizontal and portable types according to their structure. Vacuum cleaners use electric motors to drive blades to rotate at high speed, generating negative air pressure within a sealed housing to absorb dust and debris. In order to better absorb dust and debris from the target surface, vacuum cleaners on the market often increase the motor power of the vacuum cleaner. At the same time, in order to take into account the miniaturization design of the vacuum cleaner, the vacuum cleaner housing cannot be set too large. However, the use of a high-power motor in a small housing will result in a short air flow path of the vacuum cleaner, which in turn causes the vacuum cleaner to generate a lot of noise during operation. In order to reduce the noise during the use of the vacuum cleaner, an air outlet noise reduction device is needed. However, the existing air outlet noise reduction devices still have the following shortcomings:

[0003] For example, the utility model with application number 202122451954.2 discloses a noise reduction device for the air outlet of a vacuum cleaner. The utility model presses the left and right push rods relative to each other. At this time, the second spring is in a contracted state. The push rod drives the rotating rod to rotate around the connection between the rotating rod and the fixed plate through the fixed plate, so that the rotating rod drives the two blocks to move away from each other, so that the blocks are disengaged from the fixed slots. At this time, the two fixed rods are pulled away from each other, and the fixed rods are disengaged from the slots inside the sound insulation board, thereby achieving the purpose of facilitating the disassembly of the sound insulation board. However, similar to the comparative documents of the above-mentioned application, when the existing air outlet noise reduction device is used, since most air outlet noise reduction devices use noise reduction boards or sound insulation cotton to reduce noise, the noise reduction effect is easily affected after long-term use, resulting in reduced practicality and reduced efficiency of the air outlet noise reduction device.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a vacuum cleaner air outlet noise reduction device that is convenient for adjusting the wind direction is proposed. Utility Model Content

[0014] The utility model provides a noise reduction device for a vacuum cleaner air outlet that is convenient for adjusting the wind direction, and has the following beneficial effects:

[0015] 1. The utility model provides an adjustment component, and when the noise reduction device for the air outlet of a vacuum cleaner that is convenient for adjusting the wind direction is used, the movable shaft limiters are installed on both sides of the interior of the main shell by fastening screws, and the adjustment plate is rotatably connected to the main shell through the movable shaft.

[0016] 2. Through the setting of the installation component, the utility model can fix the installation sliders on both sides of the main shell by tightening bolts when the vacuum cleaner air outlet noise reduction device that is convenient for adjusting the wind direction is used. The motor protective cover is slid into the main shell by using the installation slide groove and the installation slider, and the motor body is installed in the motor protective cover. The operation of the motor body drives the air flow, and cooperates with the air guide channel set in the middle end of the motor body to evenly transport the wind to the rear, thereby reducing the impact on the use of the vacuum cleaner and improving the overall use efficiency of the vacuum cleaner.
