Vacuum cleaners generally use a motor to rotate at a high speed to generate air negative pressure in the sealed casing to absorb dust. Portable vacuum cleaners are a type of vacuum cleaner that is popular with users because of its light weight and compactness, especially in applications where space is small.

 Please refer to FIG. 1. FIG. 1 is a schematic structural view of a typical vacuum cleaner collecting device in the prior art, wherein the direction indicated by the arrow is the moving direction of the dust when the vacuum cleaner is working.

 As can be seen from the direction indicated by the arrow in the figure, in the prior art vacuum cleaner, the power motor communicates with the filter 11, the air in the dust collecting chamber 12 is extracted, and a negative pressure is formed in the dust collecting chamber 12 to make the air Under the action of the power motor, the dust passes through the dust suction pipe 13 and the air passage in turn, enters the dust collecting chamber 12, rotates around the filter 11, and gradually converges in the dust collecting chamber 12 according to the tendency of the spiral to achieve the purpose of vacuuming.

 However, as the amount of dust increases, the dust collected in the dust collecting chamber 12 is easily affected by the power motor, and tends to move toward the filter 11, so that the dust adheres to the filter 11, and the filter 11 is blocked. Filter. This not only increases the power consumption of the power motor, increases the noise of the vacuum cleaner, and reduces the dust removal efficiency; it also affects the service life of the filter 11, increases the frequency of maintenance of the filter 11, and increases the cleaning cost.

 In a preferred embodiment, the number of the second air inlet passages may be two or more, each of the second air inlet passages surrounds the bottom end of the second filter 25, and the inlet thereof is along the second filter 25. The circumferential direction is evenly distributed. As shown in FIG. 14, the bottom of the second filter 25 is provided with two spiral protrusions 34, both of which surround the second filter 25, and cooperate with the wind deflector 26 to form two spiral air inlet passages; The starting point is the entrance of the second air inlet passage, and there is a predetermined distance between the two starting points, specifically, the center of the second filter 25 is symmetrical; the end point is the bottom end of the second filter 25. Increasing the second air inlet passage can increase the ventilation amount of the second filter 25 per unit time, improve the working efficiency of the collecting device, and further improve the applicability of the collecting device. At the same time, the uniform distribution of the inlet of the second air inlet passage along the circumferential direction of the second filter 25 allows the air flow to be evenly distributed in the collecting device to make the air flow more stable.

 In addition, the second air inlet passage is formed by the spiral protrusion 34 in the figure and the wind deflector 26. Obviously, the second air inlet passage can also be formed by the groove at the bottom of the second filter 25, that is, The formation of a spiral passage inside the bottom body of the second filter 25 also satisfies the needs of the present invention and is also within the scope of the present invention. However, the second air inlet passage shown in the figure has a relatively simple structure and is easy to process, which is advantageous for reducing the production cost of the collecting device.

 Referring to FIG. 15, FIG. 15 is a schematic structural view of a fifth embodiment of the collecting device according to the present invention; the direction indicated by the arrow in the figure is the flow direction of the airflow when the collecting device is in operation.

In a fifth specific embodiment, the collecting device provided by the present invention may further include a conical air hood provided at the top end of the first filter 23, the outlet of the conical air hood and the second dust collecting chamber. 24 connected. When the collecting device is in operation, the airflow sequentially passes through the dust suction pipe 21, the first air inlet passage, the first filter 23, the second air inlet passage, and the tapered air hood, and then enters the second dust collecting chamber 24 and the second filter. 25, that is, the gas flowing out from the second air inlet passage first passes through the conical air hood to form a stronger spiral tendency, so that the dust is more away from the second filter 25 in the spiral air flow, and the second filter 25 is lowered. The load increases the service life of the second filter 25, reduces the frequency of replacement of the second filter 25, and reduces the maintenance cost of the collection device.

 Please refer to FIG. 16, FIG. 16 is a schematic structural view of a second embodiment of the second filter provided by the present invention.

 In a specific embodiment, the filter holes of the second filter 25 provided by the present invention may be strip holes. After being filtered by the first filter 23, a large volume of impurities such as hair in most of the dust has been filtered out, and it is less likely to enter the second filter 25. The strip hole is more compact and less expensive than the point hole, and is suitable for more materials, which can further reduce the processing difficulty and cost of the collecting device. Obviously, the first filter 23 and the third filter 31 can also adopt a strip-shaped filter.

 In addition to the above collecting device, the present invention also provides a vacuum cleaner including the above collecting device, the power component of the vacuum cleaner is connected to the outlet end of the second filter 25 in the collecting device, and a negative pressure is formed in the collecting device when the power component operates The dust enters the first dust collecting chamber 22 and the second dust collecting chamber 24 to achieve the technical effect of vacuum cleaning. Please refer to the existing technology for the structure of other parts of the vacuum cleaner, and will not repeat them in this article.

 Specifically, the vacuum cleaner may be a portable vacuum cleaner. The portable vacuum cleaner is widely used in modern life due to its good vacuuming effect, light weight and convenient features, especially for small corners of precision electrical appliances such as automobiles and computers. Can play a better dust removal effect. At the same time, the vacuum cleaner provided by the invention can also be a domestic large-scale horizontal vacuum cleaner and an industrial vacuum cleaner. The collection device provided by the invention can also be applied in the household horizontal vacuum cleaner and the industrial vacuum cleaner, and has the same technical effect, and should also be in the present invention. Within the scope of protection of the invention.

The above description of the collecting device and the vacuum cleaner having the same is provided for the purpose of understanding the method of the present invention and its core idea. It should be noted that those skilled in the art can, without departing from the principles of the present invention, A number of modifications and variations of the present invention are also possible, and such modifications and modifications are also intended to fall within the scope of the appended claims.
