Description

Technical Field

[0001] The present application belongs to the field of industrial vacuum cleaner air duct structures, and specifically relates to a vacuum cleaner air duct structure. Background Art

[0002] In industrial vacuum cleaners, the air duct at the outlet is shorter and wider, the wind speed is higher, and the noise is greater. Therefore, a circuitous air duct structure is designed to reduce the wind speed, increase the length of the air duct, and reduce the noise. Summary of the invention

[0003] The purpose of the embodiments of the present application is to provide a vacuum cleaner air duct structure that can solve the problem of frequent manual steps for starting the vacuum cleaner.

[0007] At least one reinforcing column is provided on the first baffle plate and the second baffle plate to strengthen the strength of the first baffle plate and the second baffle plate.

[0008] The first baffle and the second baffle are in a straight line or arc shape. The first baffle and the second baffle form a parallel gap or an arc gap. The width of the arc gap affects the airflow speed. The narrower the arc gap, the faster the airflow speed becomes, and the wider the arc gap, the slower the airflow speed becomes. Preferably, the wider the arc gap is.

[0009] The first baffle plate and the second baffle plate may also be a wave-shaped structure, and the purpose is to enhance the strength of the first baffle plate and the second baffle plate.

The first baffle, the second baffle, the first side edge and the second side edge are made of the same material and are integrally injection molded with the working layer for ease of manufacture.

[0011] The technical solution is mainly to set a first baffle and a second baffle, so that the entire air outlet duct is extended, the flow rate of the air flow is reduced, and then the noise generated by the excessive flow rate is reduced. At the same time, the strength of the first baffle and the second baffle is enhanced, the vibration and sound of the first baffle and the second baffle under the influence of wind speed are reduced, and the noise is reduced.

[0021] Example

[0022] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0023] In the following, in conjunction with the accompanying drawings, a vacuum cleaner air duct structure provided by an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0024] refer to Figure 1-7, a vacuum cleaner air duct structure provided in an embodiment of the present application may include:

[0025] like Figure 1 As shown, a cover layer 110, a working layer 120 and a barrel body 130 are provided on the main body of the vacuum cleaner 100; the cover layer 110, the working layer 120 and the barrel body 130 are arranged in sequence, wherein the barrel body 130 contains a cavity for storing dust, and the working layer 120 is used to continuously generate negative pressure in the barrel body 130; the cover layer 110 is fixed to the upper end of the working layer 120 to protect the working layer 120.

[0026] like Figure 2-7 As shown, the working layer 120 is provided with a fixed plate 121, a motor slot 122, an air outlet cavity 123, a transition zone 124, an outlet 125, a first baffle 126, a second baffle 127, a first side 128 and a second side 129; the first side 128 and the second side 129 form an air outlet cavity 123; the air outlet cavity 123 is located on the side of the motor slot 122, and an air outlet notch is provided on the side of the motor slot 122. The motor and fan assembly in the motor slot 122 suck out the gas in the barrel body 130, as described in the patent No. 2023110095331 for its suction working principle. A first baffle 126 and a second baffle 127 are provided in the air outlet cavity 123, and a gap is provided between the first baffle 126 and the second baffle 127, and the airflow in the air outlet cavity 123 passes through the gap. As shown Figure 4 As shown, the airflow in the air outlet cavity 123 can only pass through the gap between the first baffle 126 and the second baffle 127, so that the entire air outlet pipeline is extended, the flow rate of the airflow is reduced, and then the noise generated by the excessive flow rate is reduced.

[0027] At least one reinforcement column is provided on the first baffle plate 126 and the second baffle plate 127. Figure 5 As shown, a plurality of reinforcing columns are respectively provided on the first baffle plate 126 and the second baffle plate 127, the purpose of which is to increase the rigidity of the first baffle plate 126 and the second baffle plate 127 to avoid vibration when air flows through, thereby reducing the life of the first baffle plate 126 and the second baffle plate 127, and reducing vibration noise.

[0028] The first baffle plate 126 and the second baffle plate 127 are respectively connected to the first side edge 128 and the second side edge 129. The fixing plate 121 and the first baffle plate 126, the second baffle plate 127, the first side edge 128 and the second side edge 129 form an air outlet channel.

[0029] like Figure 2 As shown, the first baffle 126 , the second baffle 127 , the first side edge 128 and the second side edge 129 are made of the same material and are integrally injection molded with the working layer 120 .

[0030] The first baffle 126 and the second baffle 127 are in a straight line or arc shape. The first baffle 126 and the second baffle 127 form a parallel gap or an arc gap. Figure 6 and Figure 7 As shown, when the first baffle 126 and the second baffle 127 are in a straight line, the first baffle 126 and the second baffle 127 are parallel to each other, and there is a parallel gap between the first baffle 126 and the second baffle 127. When the first baffle 126 and the second baffle 127 are in an arc shape, an arc gap is formed between the first baffle 126 and the second baffle 127, and the arc gap increases the length of the air outlet duct, reduces the flow rate of the air flow, and then reduces the noise generated by the excessive flow rate.

[0031] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
