[0057] The utility model proposes a vacuum cleaner high-efficiency filtering dust cup structure, which is used in the dust cup design process of a handheld vacuum cleaner. The utility model does not limit the type of use environment, but the vacuum cleaner high-efficiency filtering dust cup structure is particularly suitable for floor surfaces, carpet surfaces, homes, and offices.

[0058] In general, the vacuum cleaner high-efficiency filtering dust cup structure proposed in the utility model mainly includes a dust cup 1, a dust cup upper cover 3, a dust cup bottom cover 4, a primary filter screen 6, a separation cone 7, and a fixing plate 8. Figure 1 , which shows the arrangement relationship of the dust cup 1, the dust cup upper cover 3, the dust cup bottom cover 4, the primary filter screen 6, the separation cone 7, and the fixed plate 8.

[0059] In order to achieve the purpose of improving the filtering efficiency of the dust cup for impurities and to solve the problem in the background technology that the conventional filtering system cannot filter different impurities due to the diversity of usage environments, which will lead to a decrease in filtering effect and a shortened service life of the vacuum cleaner, in the technical solution provided in this embodiment, a primary filter screen 6 and a separation cone 7 are sequentially installed in the dust cup 1 structure from the outside to the inside, and the primary filter screen 6 is used to form a downward cyclone to separate large particles, while the fine dust is adsorbed and falls into the fine dust storage chamber 71 of the separation cone 7. In addition, the airflow discharged from the dust cup upper cover 3 will also pass through the dust suction filter assembly to avoid secondary pollution of the environment, effectively improve the filtering efficiency, and increase the service life of the vacuum cleaner.

[0060] In terms of overall structure, Figure 1 , 3As shown, the dust cup 1 is cylindrical in shape, with a through hole for impurity diversion in the middle, a horizontal dust cup dust inlet 2 on the side wall, and the dust cup upper cover 3 and the dust cup bottom cover 4 are respectively installed at the top and bottom openings of the dust cup 1, and a dust cup air outlet 5 is provided on the horizontal side of the dust cup upper cover 3; in this embodiment, in order to effectively reduce the cost of disassembly and assembly, save metal parts such as springs, improve the installation efficiency of the dust cup upper cover 3 and the dust cup bottom cover 4, and reduce the difficulty of connection, a plastic elastic deformation buckle 13 is used between the dust cup upper cover 3 and the dust cup 1, and a self-elastic foot buckle 14 is used between the dust cup bottom cover 4 and the dust cup 1.

[0061] Then, if Figure 2 As shown, a fixed plate 8, a separation cone 7 and a primary filter 6 are sequentially installed in the dust cup 1 from top to bottom, wherein the primary filter 6 is arranged at the outermost side, close to the dust inlet 2 of the dust cup. Since it has a compressed air bevel end 62, the incoming air can be forced to move downward along the compressed air bevel end 62, and large particles of impurities are separated through the No. 1 filter hole 64 and fall into the dust cup 1; a coaxial separation cone 7 is installed in the primary filter 6, and the separation cone air inlet 73 of the separation cone 7 is opened at the top, and the fine dust falls into the fine dust storage chamber 71 along the separation cone air inlet 73 for classification and isolation; the fixed plate 8 is coaxially installed on the separation cone 7, which plays a role in installing the separation cone 7 and filtering the exhaust air, and a groove 85 for accommodating the installation of the dust suction filter assembly is formed on the top of the fixed plate 8. In this embodiment, the dust suction filter assembly is sequentially provided with a filter sponge 9 and a filter scouring pad 10 along the direction close to the dust cup upper cover 3.

[0062] As mentioned above, the primary filter 6 prevents dust from directly entering the dust cup 1. To this end, the primary filter 6 includes a filter body 61, a compressed air bevel end 62 and a separation end 63 from top to bottom; the filter body 61 is annular, and its outer diameter is the same as the inner diameter of the dust cup 1, and the bottom of the filter body 61 is not lower than the dust inlet 2 of the dust cup, and the compressed air bevel end 62 is integrally and reduced in diameter and arranged at the bottom of the filter body 61 and close to the dust inlet 2 of the dust cup. The compressed air bevel end 62 is an inclined structure, so the over-pressure wind bevel end 62 can be provided to force the incoming air from the dust inlet 2 of the dust cup to form a cyclone downward, thereby driving the heavier large particles of impurities to flow downward and finally accumulate in the dust cup 1;

[0063] Since the primary filter 6 also needs to drive the collection of the remaining dust, a separation end 63 is integrally provided below the compressed air inclined surface end 62 and is reduced in diameter, and a No. 1 filter hole 64 and a No. 2 filter hole 65 are provided in the circumferential direction of the separation end 63. The apertures of the No. 1 filter hole 64 and the No. 2 filter hole 65 are used to separate impurities of different sizes. At the same time, in order to cooperate with the dust cup inlet 2 to prevent dust from entering directly, the No. 1 filter hole 64 is arranged close to the dust cup inlet 2, and the top is not higher than the bottom of the dust cup inlet 2;

[0064] Preferably, a buffer end 66 is integrally provided at the bottom of the separation end 63 and extends in the horizontal direction to prevent large dust particles from colliding and impacting the dust cup 1 when falling, and a drop gap is formed between the buffer end 66 and the inner wall of the dust cup 1, and the width of the drop gap is between 12-15 mm.

[0065] It is necessary to explain in detail the structure of the separation cone 7 disposed in the primary filter 6. The separation cone 7 is provided with three sets of separation cone air inlets 73 in a circular array at the top. The separation cone air inlet 73 adopts a structure of forming a circular oblique section with the primary filter 6. When the air flows through, three cyclone sources can be formed and converge at the center of the circle to form a strong cyclone, which is used to achieve the effect of separating dust. Next, a large inclined cone surface end 72 is integrally extended at the bottom of the separation cone air inlet 73 to form a large inclined cone surface end 72. The dust separated by the three sets of separation cone air inlets 73 falls into the large inclined cone surface end 72. The inner wall of the large inclined conical surface end 72 slides down from the funnel mouth along the conical surface; secondly, a fine dust storage chamber 71 is integrally arranged at the bottom of the large inclined conical surface end 72, and the fine dust storage chamber 71 is arranged between the bottom of the primary filter screen 6 and the dust cup bottom cover 4. Under the guidance of the large inclined conical surface end 72, the dust is concentrated in the fine dust storage chamber 71, and the dust in the chamber can be in a relatively static state; in addition, one end of the bottom of the large inclined conical surface end 72 is extended and arranged in the fine dust storage chamber 71, and this part can be used to prevent fine dust from rising and block the effect of fine dust;

[0066] like Figure 6 As shown, in order to prevent the dust collected in the fine dust storage chamber 71 from escaping from the dust cup 1 and being mixed with large particles of impurities, the dust cup bottom cover 4 and the fine dust storage chamber 71 are connected by a sealing structure. Specifically, the dust cup bottom cover 4 extends upward corresponding to the bottom of the fine dust storage chamber 71 to form a bottom cover sealing ring 41, and the bottom of the corresponding fine dust storage chamber 71 extends outward to form a storage chamber sealing ring 74, and the storage chamber sealing ring 74 is clamped on the bottom cover sealing ring 41 to form a sealing structure;

[0067] At the same time, considering the stability of the installation structure of the separation cone 7, on the basis of the bolt installation between the separation cone 7 and the primary filter screen 6, the bottom of the large inclined cone end 72 is sealed on the internal structure of the buffer end 66 through the connecting end 75 extending in the horizontal direction.

[0068] On this basis, if Figure 3 and 9As shown, a groove 85 for installation is provided on the top of the fixed disk 8 corresponding to the dust suction and filtering assembly, and a disassembly and assembly portion 88 is also integrally provided on the upper surface of the groove 85 to facilitate the installation and maintenance of the structure; secondly, in order to exhaust the corresponding separation cone 7, a fixed disk air inlet 82 is integrally extended downward on the side of the fixed disk body 81 away from the groove 85, wherein a transition structure is formed between the fixed disk air inlet 82 and the groove 85 by chamfers 83 and vertical walls 84. When in use, due to the tapered structure formed by the inner wall of the groove 85, the dust separated by the dust suction and filtering assembly slides down along the taper to the vertical wall 84 of the fixed disk air inlet 82, and then slides down into the separation cone 7, so as to be uniformly collected in the fine dust storage chamber 71 below; further, the position of the fixed disk air inlet 82 is lower than the lower end of the dust cup dust inlet 2, which is conducive to the formation of a cyclone and improves the collection efficiency of fine dust.

[0069] like Fig.10 As shown, the gas filtered by the dust suction filter assembly needs to be discharged from the dust cup outlet 5 of the dust cup upper cover 3. For this purpose, a vertically arranged wind guide rib 11 is provided on the dust cup upper cover 3 directly above the dust suction filter assembly. The wind guide rib 11 is provided with multiple groups, and the wind guide channels formed between the multiple groups of wind guide ribs 11 are all arranged in the direction of the dust cup outlet 5, which helps to reduce the noise volume when the airflow passes through the dust cup during the use of the vacuum cleaner. At the same time, it can also optimize the airflow distribution at the outlet, avoid the situation where the local airflow is too large or too small, and improve the dust collection efficiency of the vacuum cleaner.

[0070] Combined with Figure 4 and 5 As shown, in order to improve the connection strength and sealing strength between the various components in the dust cup structure and prevent the collected dust from escaping from the dust cup 1, on the one hand, the top inner ring and outer ring of the fixed plate body 81 are respectively provided with a fixed plate sealing ring 86 corresponding to the dust cup upper cover 3 and the top of the dust cup 1. Similarly, a dust cup bottom cover sealing ring 12 is also provided between the dust cup bottom cover 4 and the dust cup 1, which strengthens the sealing between the dust cup upper cover 3 and the dust cup bottom cover 4 and the dust cup 1; on the other hand, the top of the separation cone air inlet 73 is abutted against the bottom of the fixed plate body 81, and a sealing gasket 87 is provided between the two, which strengthens the sealing effect between the top of the separation cone 7 and the fixed plate 8.

[0071] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
