Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum cleaners, and in particular relates to a high-efficiency cyclone dust and gas separation dust cup. Background Art

[0002] A vacuum cleaner is a household appliance that is primarily used to remove dust, debris, and small particles from floors, carpets, furniture, and other surfaces. It uses a motor to generate suction, sucking dust and debris into a dust collection container to achieve the purpose of cleaning.

[0003] However, most vacuum cleaners currently on the market use a single-stage cyclone separation method to separate dust from air. While this technology can achieve dust and air separation to a certain extent, its separation effect is not satisfactory. After long-term use, the HEPA filter (high-efficiency air filter) inside the vacuum cleaner tends to clog, which not only affects the suction power of the vacuum cleaner, but may also cause performance degradation or even damage the vacuum cleaner.

[0004] Specifically, the separation effectiveness of primary cyclone separation technology is significantly limited. First, the centrifugal force applied to fine dust particles with smaller particle sizes is weak, making effective separation difficult. These fine dust particles are often discharged along with the cleaner air, reducing the dust removal efficiency of the vacuum cleaner. Second, the airflow distribution within the primary cyclone separator is often uneven, which also affects the separation effect. In the case of uneven airflow, dust particles in certain areas may not be subjected to sufficient centrifugal force, making effective separation impossible.

[0005] At present, China has patented a dust-gas separation device for a dust cup of a vacuum cleaner (CN1 13317718B), which includes a dust cup body, an air inlet is provided at the bottom of the dust cup body, a dust bucket is provided on the dust cup body, a dust-gas separation component is provided in the dust bucket, and the dust-gas separation component includes a filter channel and a cyclone cone, one end of the filter channel is connected to the air inlet, and the other end of the filter channel is provided with an air outlet, the filter channel spirally rises, the cyclone cone is installed above the filter channel, the filter channel is connected to a dust-flinging hood, and the cyclone cone is located in the dust-flinging hood, and the dust-flinging hood is provided with an ash-flinging port. The dust-laden airflow enters the filter channel from the air inlet, and after separation by the cyclone cone, the dust is thrown out from the ash-flinging port and enters the dust bucket, and the filtered dust-laden airflow flows out from the air outlet. The present invention also provides a vacuum cleaner. Compared with the prior art, the present invention can effectively solve the problem of low dust-gas separation efficiency in the dust cup of a vacuum cleaner.

[0006] A Chinese patent discloses a dust and gas separation assembly for a vacuum cleaner and a vacuum cleaner (CN1 09330483B), wherein the dust and gas separation assembly includes a dust cup assembly, a cyclone separator, a first baffle, a second baffle, and a filter assembly. The dust cup assembly is provided with an air inlet and an air outlet. The cyclone separator is arranged in the dust cup assembly. The first baffle is arranged on the inner peripheral wall of the dust cup assembly, and the first baffle has a first through hole. The second baffle is arranged on the outer peripheral wall of the cyclone separator, and the second baffle has a second through hole. The filter assembly is arranged downstream of the cyclone separator, and the filter assembly includes a filter element and a bracket. The filter element is sleeved in the bracket, and the filter element has a first air outlet channel, which is connected to the cyclone separator, and the bracket has a second air outlet channel connected to the first air outlet channel. According to the dust and gas separation assembly of the utility model, by providing the first baffle and the second baffle, the dust deposition stability can be improved, thereby improving the dust and gas separation efficiency of the dust and gas separation assembly.

[0007] A Chinese patent discloses a dust cup and a vacuum cleaner having the same (CN1 07752905B). The dust cup comprises: a dust cup body, the dust cup body being formed with an air inlet and an air outlet; a dust and air separator, the dust and air separator being disposed at the top of the dust cup body, the dust and air separator having an air outlet channel communicating with the air outlet, the dust and air separator having an upwardly concave dust and air separation groove formed on the bottom surface of the dust and air separator, the dust and air separation groove being located outside the air outlet channel; and a channel member, the channel member being disposed within the dust cup body, the channel member having a lower end connected to the air inlet, the channel member having an upper end extending into the dust and air separation groove and spaced apart from the inner wall of the dust and air separation groove, the channel member defining an air inlet channel communicating with the air outlet channel, a portion of the air inlet channel being configured as a spiral channel for spirally guiding dust entering from the air inlet to the dust and air separator. The dust cup of the present invention has a simple structure and is easy to clean, thereby improving the dust and air separation efficiency of the dust removal device and reducing pressure loss.

[0008] The existing patents have solved the problem of dust-gas separation efficiency to a certain extent, but it is still easy for large dust particles to enter the HEPA and clog it, increasing its clogging efficiency and failing to effectively solve the problem of dust-gas separation. Utility Model Content

[0009] The purpose of this utility model is to solve the problem that the dust and gas separation method of the dust cup of vacuum cleaners currently on the market mostly uses a single-stage cyclone separation technology. Although this technology can achieve dust and gas separation to a certain extent, its separation effect is not satisfactory. After long-term use, the HEPA (high-efficiency air filter) inside the vacuum cleaner is prone to clogging, which not only affects the suction power of the vacuum cleaner, but may also cause the vacuum cleaner performance to decline or even damage. Therefore, a high-efficiency cyclone dust and gas separation dust cup is proposed.

[0010] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: a high-efficiency cyclone dust and gas separation dust cup, including a dust cup body, a HEPA filter element is arranged on the top of the dust cup body, a bottom cover is arranged on the bottom of the dust cup body, and a first-stage filter element, a second-stage filter element and a third-stage filter element are arranged in sequence inside the dust cup body.

[0023] As a further description of the above technical solution:

[0024] The rotatable air guide cover is provided with a connecting shaft, and the connecting shaft is rotatably connected to the three-stage filter element.

[0025] As a further description of the above technical solution:

[0029] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0030] 1. In the utility model, a primary filter element, a secondary filter element and a tertiary filter element are provided, and they cooperate with the HEPA filter element, wherein the interior of the secondary filter element and the rotatable air guide cover at the bottom of the primary filter element form a conical rotating groove. When the machine is working, dust and air flow enter the dust cup and pass through the primary filter element, the secondary filter element and the tertiary filter element in sequence. The primary filter element filters large particles, the secondary filter element filters fine particles, and the tertiary filter element filters fine dust. When air flows through the three-stage filtration, the rotatable air guide cover automatically rotates due to the force in its spirally arranged air guide holes. The air flow passes through the air guide holes and enters the HEPA upward. The fine dust enters the dust collecting tank along the dust guide groove by centrifugal force and gravity, thereby realizing efficient dust and gas separation. This structure greatly improves the dust and airflow separation effect, avoids dust clogging the HEPA for a long time and affecting the service life of the vacuum cleaner.

[0031] 2. In the present invention, the dust guide groove is in an inward conical shape, and the dust guide groove and the dust collecting groove cooperate with each other to form a dust collecting groove. When the dust enters the dust collecting groove, due to the conical shape of the bottom of the dust guide groove, the dust is blocked at the bottom of the dust guide groove when the machine is working, thereby preventing the dust from being raised again and affecting the separation effect of dust and airflow.

[0032] 3. In the present invention, the filter holes of the primary filter element, the secondary filter element and the filter mesh in the air guide hole are reduced in sequence to achieve multi-layer filtration, reduce the chance of dust entering the HEPA, and improve the efficiency of separating the dust airflow between the tertiary filter element and the secondary filter element.

[0048] The dust cup body 1 is provided with a dust suction port 7 , and dust enters the primary filter element 4 , the secondary filter element 5 and the tertiary filter element 6 in sequence from the dust suction port 7 .

[0049] The HEPA filter element 2 is connected to the tertiary filter element 6 .

[0050] The filter holes of the primary filter element 4 and the secondary filter element 5 are successively reduced, filtering the dust from large to small.

[0051] The secondary filter element 5 is sleeved and connected to the peripheral side of the tertiary filter element 6 , the primary filter element 4 is sleeved and connected to the peripheral side of the secondary filter element 5 , and the secondary filter element 5 extends to the bottom cover 3 .

[0052] The bottom of the three-stage filter element 6 is provided with a rotatable air guide cover 8, and the rotatable air guide cover 8 is provided with a plurality of air guide holes 9, and the plurality of air guide holes 9 are arranged in a spiral shape. Dust and airflow enter the dust cup and pass through the first-stage filter element, the second-stage filter element and the third-stage filter element in sequence. The first-stage filter element filters large particles, the second-stage filter element filters fine particles, and the third-stage filter element filters fine dust. When airflow passes through the three-stage filter, the rotatable air guide cover automatically rotates due to the force of its spirally arranged air guide holes. The airflow passes through the air guide holes and enters the HEPA upward. The fine dust enters the dust collecting tank along the dust guide groove due to centrifugal force and gravity, thereby achieving efficient dust and air separation. This structure greatly improves the dust and airflow separation effect.

[0053] One end of the bottom cover 3 is hinged to the outer wall of the dust cup body 1 , and the other end of the bottom cover 3 is provided with a clamping block 10 . The dust cup body 1 is provided with an abutting block 11 , and the clamping block 10 is clamped on the abutting block 11 .

[0054] The rotatable air guide cover 8 is provided with a connecting shaft 12, and the connecting shaft 12 is rotatably connected to the three-stage filter element 6, so that the rotatable air guide cover can be rotated by force.

[0055] A dust guide groove 13 is provided inside the secondary filter element 5 . The dust guide groove 13 is conical and located at the bottom of the rotatable air guide cover 8 .

[0056] The bottom of the dust guide groove 13 is provided with a dust collecting groove 14, the dust collecting groove 14 is communicated with the dust guide groove 13, and the dust collecting groove 14 abuts against the bottom cover 3. To avoid collecting dust falling due to gravity,

[0057] It can then be removed by opening the bottom cover.

[0058] Working principle: By setting up a primary filter element, a secondary filter element and a tertiary filter element, and cooperating with the HEPA filter element, the interior of the secondary filter element and the rotatable air guide cover at the bottom of the primary filter element form a conical rotating groove. When the machine is working, dust and air flow enter the dust cup and pass through the primary filter element, the secondary filter element and the tertiary filter element in turn. The primary filter element filters large particles, the secondary filter element filters fine particles, and the tertiary filter element filters fine dust. When air flows through the three-stage filter, the rotatable air guide cover automatically rotates due to the force of its spirally arranged air guide holes. A filter is provided inside, and the air flow passes through the air guide holes and enters the HEPA upwards. The fine dust enters the dust collecting trough along the dust guide groove through centrifugal force and gravity, thereby realizing efficient dust and air separation. This structure greatly improves the dust and airflow separation effect, and avoids the dust clogging the HEPA for a long time, which affects the service life of the vacuum cleaner. At the same time, the dust guide groove is inward-facing conical, and the dust guide groove and the dust collecting groove cooperate with each other to form a dust collecting trough. When the dust enters the dust collecting trough, due to the conical shape of the bottom of the dust guide groove, the dust is blocked at the bottom of the dust guide groove when the machine is working, avoiding the dust from being raised again and affecting the separation effect of dust and airflow.

[0059] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
