When the air flow passes through the noise reduction piece 301, the air flow is divided into a plurality of beams by the noise reduction piece 301 and flows through the corresponding through holes 3012-1, so that the cross sectional area of the cross section of each beam of air flow is reduced, and the noise of the blower during operation is reduced.

Therefore, one of the noise reduction pieces 301 is damaged, the damaged noise reduction piece 301 can be maintained and replaced, the whole noise reduction assembly 300 does not need to be removed, and the noise reduction piece 301 is convenient to disassemble and replace, and meanwhile the material cost is saved.

The embodiment of the application shown in fig. 1 provides a schematic structural explosion diagram of a blower; fig. 2 shows an enlarged view of the portion a in fig. 1.

In some embodiments of the present application, the noise reduction member 301 includes a fixing portion 3011 and a noise reduction portion 3012, the fixing portion 3011 is disposed at an outer periphery of the noise reduction portion 3012, the fixing portion 3011 is detachably connected to an inner wall of the air duct 204, and the through hole 3012-1 is disposed at the noise reduction portion 3012.

Equivalently, the fixing part 3011 is a frame of the noise reduction part 3012, and mainly plays a role in bearing and mounting; the noise reduction portion 3012 is provided with a through hole 3012-1 to mainly serve as a shunt. The shape of the noise reduction member 301 is adapted to the cross-sectional shape of the air duct 204, and may be rectangular, triangular, circular, or other structures.

For example, when the cross-sectional shape of the air duct 204 is circular, the cross-sectional shape of the noise reduction member 301 is also circular, the fixing portion 3011 may be circular, the noise reduction portion 3012 may be a plurality of crisscross grid bars, the plurality of grid bars are connected to the fixing portion 3011, a plurality of honeycomb-shaped through holes 3012-1 are surrounded by the crisscross grid bars, and the honeycomb-shaped through holes 3012-1 may be understood as regular hexagons.

The fixing portion 3011 and the noise reduction portion 3012 may be integrally formed, that is, a plurality of circular through holes 3012-1 are formed in an array on the noise reduction member 301, a certain space is reserved at an edge portion of the noise reduction member 301 to form the fixing portion 3011 for mounting the noise reduction member 301, and a region on the noise reduction member 301 where the through holes 3012-1 are formed forms the noise reduction portion 3012.

In some embodiments of the present application, one of the noise reducer 301 and the inner wall of the air duct 204 is provided with a positioning protrusion 3011-1, and the other of the noise reducer 301 and the inner wall of the air duct 204 is provided with a positioning groove 2023 that is in positioning engagement with the positioning protrusion 3011-1.

That is, a positioning protrusion 3011-1 may be provided on the fixing portion 3011 of the noise reduction member 301, the positioning protrusion 3011-1 extends from a side of the fixing portion 3011 near the noise reduction portion 3012 to a side facing away from the noise reduction portion 3012, and a positioning groove 2023 is correspondingly formed in an inner wall of the air duct 204. When the noise reduction member 301 is mounted on the inner wall of the air duct 204, the positioning protrusion 3011-1 is embedded in the positioning groove 2023 to achieve positioning, and then the rest of the noise reduction member 301 is mounted at a corresponding position on the inner wall of the air duct 204.

When the blower is in use, the positioning protrusion 3011-1 cooperates with the positioning groove 2023 to also play a limiting role, so as to prevent the noise reduction member 301 from moving along the inner wall of the air duct 204 under the action of air flow.

The noise reduction member 301 may be adhered to and fixed on the inner wall of the air duct 204, or may be fixed on the inner wall of the air duct 204 by a fastening connection manner, or may be connected on the inner wall of the air duct 204 by an embedding manner.

In some embodiments of the present application, in order to further improve the noise reduction effect, the through holes 3012-1 on two adjacent noise reduction members 301 are arranged in a staggered manner, i.e. the positions of the through holes 3012-1 on two adjacent noise reduction members 301 do not correspond.

For example, two noise reduction pieces 301 are sequentially disposed along the direction from the air inlet 2031 to the air outlet 101, i.e. along the flow direction of the air flow in the air duct 204, where the noise reduction piece 301 close to the air inlet 2031 is denoted as a first noise reduction piece, the noise reduction piece 301 close to the air outlet 101 is denoted as a second noise reduction piece, the through hole 3012-1 on the first noise reduction piece and the through hole 3012-1 on the second noise reduction piece are arranged in a staggered manner, i.e. the second noise reduction piece is projected forward onto the first noise reduction piece, and the through hole 3012-1 on the first noise reduction piece and the through hole 3012-1 on the second noise reduction piece are not overlapped.

When the airflow flows from the air inlet 2031 to the air outlet 101, the large-cluster airflow is firstly split into a plurality of small-cluster airflows through the first noise reduction piece, and the plurality of small-cluster airflows are further split when passing through the second noise reduction piece, so that the distribution of the plurality of small-cluster airflows is finer, the cross-sectional area of each airflow can be further reduced, and the noise generated by cutting the plurality of small-cluster airflows by the fan blade is smaller.

In some embodiments of the present application, the hole diameters of the through holes 3012-1 of the noise reduction pieces 301 gradually decrease from the air inlet 2031 to the air outlet 101, that is, along the flow direction of the air flow in the air duct 204, after the hole diameters of the through holes 3012-1 decrease, the number of the through holes 3012-1 distributed on the noise reduction pieces 301 increases, so when the air flow flows from the air inlet 2031 to the air outlet 101, the plurality of noise reduction pieces 301 arranged at intervals can divide the air flow more finely, and the noise reduction effect is better.

In some embodiments of the present application, a plurality of mounting grooves 2024 are spaced along the inner wall of the air duct 204 along the flow direction of the air flow in the air duct 204, and each noise reduction member 301 is disposed in a corresponding mounting groove 2024.

In the above embodiment, when the air flow passes through the noise reduction member 301, the air flow is split into a plurality of small air flows by the noise reduction member 301, and the small air flows through the corresponding through holes 3012-1, so as to reduce the cross-sectional area of each air flow, thereby reducing the high-frequency noise generated by cutting each air flow by the fan blade, and further achieving the purpose of noise reduction. The noise reduction member 301 converts high-frequency noise generated by dividing the whole air flow into a plurality of small air flows into mechanical vibration energy, and the mechanical vibration energy is absorbed by the noise reduction member 302, so that the noise reduction effect can be further improved.

That is, the width of the noise reducing member 302 corresponds to the gap between the adjacent two noise reducing members 301 such that the noise reducing member 302 is in direct contact with the adjacent two noise reducing members 301, and the noise generated by the air flow passing through the noise reducing members 301 is absorbed to reduce the noise generated by the operation of the blower.

In the embodiment of the present application, an air guide member, an air duct sleeved on the outer side of the air guide member, an air nozzle installed at the front ends of the air guide member and the air duct, and an end cover installed at the rear ends of the air guide member and the air duct are provided in the blower main body 100.

In addition, a heating assembly is further disposed inside the blower main body 100, and the heating assembly is disposed on the air guide member, and may be a heating wire. When the air flow passes through the air duct 204, if the heating wire is electrified to generate heat, the blower blows out hot air; if the heating wire does not work, the blower blows cold air.

In addition, since noise is generated when the motor works during the operation of the fan assembly 400, a damping sleeve is sleeved on the outer side of the motor in order to reduce noise caused by vibration of the motor. The damping sleeve can be a rubber buffer.

According to the blower provided by the embodiment of the application, the noise reduction assembly 300 is arranged in the air passage, the noise reduction assembly 300 comprises at least two noise reduction pieces 301 arranged at intervals, each noise reduction piece 301 is detachably connected to the inner wall of the air passage 204, and a plurality of through holes 3012-1 are formed in each noise reduction piece 301 in a penetrating manner. When the motor drives the fan blade to rotate, air is sucked from the air inlet 2031, and the centrifugal air flow thus formed is blown out from the air outlet 101 through the air duct 204. When the air flow passes through the noise reduction piece 301, the air flow is divided into a plurality of beams by the noise reduction piece 301 and flows through the corresponding through holes 3012-1, so that the cross sectional area of the cross section of each beam of air flow is reduced, and the noise of the blower during operation is reduced.

Further, when the air flow passes through the noise reduction member 301, the air flow is split into a plurality of small air flows by the noise reduction member 301, and the small air flows through the corresponding through holes 3012-1, so that the cross sectional area of each air flow is reduced, the high-frequency noise generated by cutting each air flow by the fan blade is reduced, and the purpose of noise reduction is further achieved. The noise reduction member 301 converts high-frequency noise generated by dividing the whole air flow into a plurality of small air flows into mechanical vibration energy, and the mechanical vibration energy is absorbed by the noise reduction member 302, so that the noise reduction effect can be further improved.

Finally, it should be noted that: the above embodiments are only for illustrating the present application, and are not limiting of the present application. While the application has been described in detail with reference to the embodiments, those skilled in the art will appreciate that various combinations, modifications, or equivalent substitutions can be made to the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application, and it is intended to be covered by the scope of the claims of the present application.
