The dust cup assembly 1 of the vacuum cleaner of the embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1, a dust cup assembly 1 of a vacuum cleaner according to an embodiment of the present invention includes a dust cup 11, a dust cup upper cover 12, a sound absorbing partition 13, and a dust separating device 14.

Specifically, the upper end of the dust cup 11 is open, and a dust inlet 101 is formed on the side wall or the bottom wall of the dust cup 11. The dust cup upper cover 12 is covered at the upper end of the dust cup 11, and the dust cup upper cover 12 is formed with a dust outlet 102. The muffler partition 13 is disposed on the inner side of the dust cup upper cover 12, and the muffler partition cooperates with the inner surface of the dust cup upper cover 12 to form the muffler cavity 103. The dust separation device 14 is provided in the dust cup 11, the inlet of the dust separation device 14 is in communication with the dust inlet 101, and the outlet of the dust separation device 14 is in communication with the dust outlet 102. The dust-containing gas enters the dust cup from the dust inlet 101 formed on the side wall or the bottom wall of the dust cup 11, and after the dust separation device 14 performs the dust separation, the dust is left in the dust cup 11, and the dust is left. The dust cup assembly 1 will be discharged from the dust outlet 102.

According to the dust cup assembly 1 of the vacuum cleaner according to the embodiment of the present invention, since the sound-damping partition 13 is provided on the dust cup upper cover 12, the muffler chamber formed between the sound-damping partition 13 and the inner surface of the dust cup upper cover 12 will dust. A part of the noise formed in the cup assembly 1 is separated from the outside, so that the noise in the working of the dust cup assembly 1 can be reduced.

As shown in FIG. 1, the dust cup upper cover 12 includes a top wall 121 and a side wall 122. The side wall 122 of the dust cup upper cover 12 is connected to the edge of the top wall 121 of the dust cup upper cover 12, and the dust outlet 102 is formed in the dust. The side wall 122 of the top cover 12 of the cup. Therefore, it is convenient to discharge the airflow from the dust outlet 102 into the steady flow chamber of the vacuum cleaner, to facilitate the connection of the components of the vacuum cleaner, to rationalize the position of the components, and to simplify the structure of the vacuum cleaner.

Of course, the dust outlet 102 of the present invention can also be placed at other locations on the dust cup cover 12.

As shown in FIG. 1, the periphery of the sound absorbing partition 13 is connected to the side wall 122 of the dust cup upper cover 12. Therefore, the sound insulation effect of the muffler separator 13 can be improved.

As shown in Fig. 1, a portion of the circumference of the sound absorbing partition 13 is connected to the side wall 122 of the dust cup upper cover 12 adjacent to the dust cup 11, and the other portion of the periphery of the sound absorbing partition 13 is connected to the dust outlet. At least a portion of the perimeter of 102. This makes it easier to circulate airflow and reduce noise.

As shown in FIG. 1, the sound absorbing partition 13 is configured to extend from the position of the side wall 122 of the dust cup upper cover 12 adjacent to the dust cup 11 toward the upper portion of the periphery of the dust outlet 102 to form an arc-shaped wind deflector shape. Therefore, the arc-shaped air deflector-shaped muffler plate 13 can facilitate the airflow to guide the island dust air outlet 102, thereby reducing the flushing action of the airflow on the muffler diaphragm 13, not only making the airflow flow stably and rapidly, but also improving the dust. The dust suction effect of the vacuum cleaner of the cup assembly 1 can also reduce the noise generated when the airflow flows through the sound absorbing partition 13, thereby further improving the noise cancellation effect of the dust cup assembly 1.

Of course, the sound absorbing partition 13 of the present invention may be provided in a flat shape or other shape as will be understood by those skilled in the art.

In some embodiments of the invention, the sound attenuating partition 13 and the dust cup upper cover 12 are joined by welding, bonding, bolting or snapping. Therefore, the sound absorbing partition 13 can be stably connected to the dust cup upper cover, the stability of the sound absorbing partition 13 is improved, and the problem that the sound absorbing partition 13 is dropped or displaced causes the sound absorbing failure to be avoided.

Moreover, the muffler partition 13 and the dust cup upper cover 12 are separately formed into two parts, and then, when the two parts are assembled together, the production process of the dust cup assembly 1 can be simplified, and the cost of the dust cup assembly 1 can be reduced.

In addition, the muffler plate 13 of the present invention can also be integrally molded or integrally blow molded with the dust cup upper cover 12, and integrally formed with the dust cup upper cover 12 through the muffler plate 13 to improve the muffler plate 13 and the dust cup. The cover 12 is molded efficiently, and the sealing performance and the joint strength of the joint of the sound-damping partition 13 and the dust cup upper cover 12 are also improved, thereby further improving the sound-absorbing effect of the dust cup assembly 1.

As shown in FIG. 1, in some embodiments of the present invention, in order to further improve the structural strength and stability of the sound absorbing partition 13, a reinforcing rib 123 is connected between the sound absorbing partition 13 and the dust cup upper cover 12. One end of the reinforcing rib 123 is connected to the inner top wall surface of the dust cup upper cover 12, and the other end of the reinforcing rib 123 is connected to the surface of the side of the muffling partition 13 facing the top wall of the dust cup upper cover 12, and The reinforcing ribs 123 may be in the form of a rod, a flat plate, an arc-shaped plate or the like, and the reinforcing ribs 123 may also be a plurality of one or spaced apart to avoid deformation or displacement of the sound-damping partition 13 .

In addition, when the muffler plate 13 is curved toward the top wall of the dust cup upper cover 12, the muffler plate 13 can be prevented from being affected by gravity, thereby improving the structural stability and silencing of the dust cup assembly 1. effect.

Preferably, the dust separation device 14 of the present invention is a cyclone separator, the inlet of the cyclone separator is in communication with the dust inlet 101, and the outlet of the cyclone separator is in communication with the dust outlet 102, which can be improved by the cyclone separator. The effect of the dust separation of the dust cup assembly 1.

Of course, other forms of dust separation devices of the prior art can also be used in the present invention.

The invention adds a sound-damping partition 13 on the inner side of the dust cup upper cover 12 on the basis of the original dust cup assembly, so that a hollow layer is formed on the dust cup upper cover 12, and the vibration generated by the airflow flushing is transmitted to the outside, and The silencing shape of the muffler partition is recessed toward the top wall of the dust cup upper cover 12, which can act as a flow guiding effect on the airflow, thereby reducing the noise of the whole machine.

Wherein, the muffler partition of the present invention extends upward from the side wall 122 of the dust cup upper cover 12 adjacent to the dust cup 11 and toward the dust inlet 101, and is connected to the upper edge of the dust inlet 101.

2 is a schematic view showing the structure of a vacuum cleaner 100 of the present invention. As can be seen from FIG. 2, the vacuum cleaner 100 of the present invention comprises: a dust cup assembly 1, a flow stabilization chamber 2, and a dust cup assembly 1 according to the foregoing implementation of the present invention. The dust cup assembly of the vacuum cleaner of the example; the inlet of the stabilization chamber 2 is in communication with the dust outlet 102 of the dust cup assembly 1. Since the vacuum cleaner 100 employs the dust cup assembly 1 according to the foregoing embodiment of the present invention, the noise of the cleaner 100 is reduced, thereby making it more convenient for the user to use, and providing the user with a good use environment.
