Detailed Description
Fig. 1-5 show a preferred embodiment of the cyclone dust-air separation structure of the present invention, which comprises a dust cup 1 and a cyclone tube 2 accommodated in the dust cup, wherein the dust cup 1 comprises an air inlet (not labeled), a dust collection chamber 101 located at the bottom of the dust cup and an air outlet 102 located at the top of the dust cup, and the cyclone tube 2 comprises a cyclone chamber 201 formed inside and in sealed communication with the dust collection chamber 101 and the air outlet 102, respectively.
The key improvement of the embodiment lies in that the structure of the cyclone 2 is optimally designed, and the cyclone 2 further comprises a first wind guiding cambered surface 202, a second wind guiding cambered surface 203 and a vent hole 204 formed on the first wind guiding cambered surface. Wherein:
the first air guiding cambered surface 202 is formed on the outer wall of the cyclone cylinder 2, the first air guiding cambered surface 202 extends to the inside of the cyclone cylinder 2, and meanwhile, the first air guiding cambered surface 202 is perpendicular to the central axis of the cyclone cylinder 2.
The second air guiding cambered surface 203 is formed on the inner wall of the cyclone cylinder 2, the second air guiding cambered surface 203 extends to the outside of the cyclone cylinder 2, and meanwhile, the second air guiding cambered surface 203 is arranged in parallel with the central axis of the cyclone cylinder.
The ventilation hole 204 is formed between the first air guiding cambered surface and the second air guiding cambered surface.
In order to enhance the separation effect of the dust-air separation structure, in this embodiment, a primary cyclone cone 5 and a secondary cyclone cone 6 are further added in the dust cup 1, wherein the primary cyclone cone 5 is located at the periphery of the cyclone cylinder 2, an air guide hole (not labeled in the figure) facing the first air guide arc surface 203 is formed in the primary cyclone cone 5, and the secondary cyclone cone 6 is hermetically communicated between the air outlet 102 and the cyclone cavity 201. Therefore, an annular cylindrical primary cyclone space is formed between the dust cup 1 and the primary cyclone cone 5, an annular cylindrical secondary cyclone space is formed between the cyclone cylinder 2 and the secondary cyclone cone 6, and the cyclone effect is better.
Referring to fig. 2, the secondary cyclone cone 6 is a cylindrical structure extending downward from the air outlet 102 (i.e. extending into the cyclone), and the dust cup 1, the primary cyclone cone 5, the cyclone 2 and the secondary cyclone cone 6 are coaxially arranged.
Referring to fig. 2 and 3, in operation, the wind entering the dust cup 1 from the wind inlet of the dust cup first rotates and flows upwards in the annular space between the inner wall of the dust cup 1 and the primary cyclone cone 5 to form primary cyclone. A part of the particles in the wind fall into the dust collecting chamber 101 by the cyclone effect. When the wind blows upwards from the wind guide hole of the primary cyclone cone 5 to the wind guide cambered surface 202 of the cyclone cylinder 2, the wind is blocked by the first wind guide cambered surface 202 and flows into the interior of the cyclone cylinder 2 from the wind guide hole 204 under the guidance of the first wind guide cambered surface 202. After the wind enters the ventilation hole 204, the wind is screwed into the cyclone chamber 201 under the blocking and guiding of the second wind guiding cambered surface 203, and a secondary cyclone is formed between the cyclone cylinder 2 and the secondary cyclone cone 6. The other part of the particle dust in the cyclone wind flow is separated downwards and falls into the dust collection cavity 101, and the relatively clean wind body passes through the secondary cyclone cone 6 and the air outlet 102 upwards and flows out in sequence.
In order to further improve the cleanliness of the air flowing out of the outlet 102, the filter cotton 4 is disposed at the outlet 102.
In addition, in order to ensure that the air can smoothly enter the vent hole 204 from the first air guiding cambered surface 202 and smoothly flow to the second air guiding cambered surface 203 from the vent hole 204, in this embodiment, a part of hole walls of the vent hole 204 are formed on the first air guiding cambered surface 202 and the second air guiding cambered surface 203. Specifically, a certain radial cross section of the ventilation hole 204 and the central axis of the cyclone 2 are on the same plane, the ventilation hole 204 has an upper side hole wall surface axially close to the top of the cyclone and an outer side hole wall surface radially far away from the central axis of the cyclone, wherein the upper side hole wall surface of the ventilation hole 204 is formed on the first air guiding arc surface 202, and the outer side hole wall surface of the ventilation hole 204 is formed on the second air guiding arc surface 203.
In addition, in order to further enhance the cyclone strength of the wind flow in the cyclone 2, the following optimization design is further made on the structure of the cyclone 2 in the embodiment:
the first air guiding cambered surface 202 has an upper end portion close to the vent hole 204 and a lower end portion far from the vent hole 204. And, the upper end of the first wind guiding cambered surface 202 is arranged in a tangent manner with a certain plane perpendicular to the central axis of the cyclone cylinder. The second wind directing curved surface 203 has an outer end close to the ventilation hole 204 and an inner end far from the ventilation hole 204. And the outer end part of the second wind guide cambered surface 203 is arranged in a tangent way with a certain cylindrical surface which is coaxially arranged outside the central axis of the cyclone cylinder.
In this way, the wind flow guided by the first guide slope 202 can flow into the ventilation hole 204 in the horizontal direction in fig. 2, and then smoothly flows to the second wind guiding arc surface 203 from the ventilation hole 204 in the tangential direction.
In order to further enhance the cyclone effect of the wind flow in the cyclone 2, in the embodiment, the wind guide tube 3 extending downward into the cyclone 2 is disposed at the wind outlet 102, an annular cyclone space is formed between the outer wall of the wind guide tube 3 and the inner wall of the cyclone 2, and the wind flow needs to flow to the wind outlet 101 through the inner channel of the wind guide tube 3. And the air duct 3, the cyclone 2 and the dust cup 1 are coaxially arranged.
The dust cup 1 includes a bottom cover 103 detachably connected to a bottom thereof, a portion of the dust chamber 101 is formed on the bottom cover 103, and the dust in the dust chamber 101 can be discharged after the bottom cover 103 is removed.
In this embodiment, the first wind guiding cambered surfaces 202, the second wind guiding cambered surfaces 203 and the vent holes 204 are respectively provided with six wind guiding cambered surfaces, and are uniformly distributed at intervals along the circumferential direction. Correspondingly, six air guide holes are also formed in the primary cyclone cone 5.
