[0002] In the existing technology, vacuum cleaners are widely used in household and commercial cleaning fields. One of their core components is the filter element, which is set in the dust cup to filter the airflow entering the dust cup, thereby filtering out dust and impurities in the airflow to ensure that the exhaust air is clean.

[0003] However, in existing vacuum cleaners, during long-term use, the airflow enters the dust cup and comes into direct contact with the filter, causing dust and impurities to accumulate directly on the filter's surface, which can easily lead to clogging. This not only reduces the vacuum cleaner's suction efficiency and affects the cleaning effect, but may also shorten the filter's lifespan and increase maintenance costs.

[0004] Therefore, there is an urgent need for a dust cup structure and a vacuum cleaner to solve the above problems. Utility Model Content

[0044] This embodiment provides a dust cup structure, such as Figures 1-6As shown, the dust cup structure includes a dust cup 100, a filter element 200, a spiral air duct 140, and a dust baffle 300. The dust cup 100 is a hollow structure. One end of the dust cup 100 is provided with an air outlet 110, and the other end is provided with a bottom cover 120. The side wall of the dust cup 100 is provided with an air inlet 130. The filter element 200 is disposed inside the dust cup 100 near the air outlet 110. The filter element 200 is used to filter the airflow blown out from the dust cup 100. The spiral air duct 140 is provided inside the dust cup 100. The spiral air duct 140 extends spirally from the air inlet 130 to the bottom cover 120 to guide the airflow at the air inlet 130 to flow towards the bottom cover 120. Along the axial direction of the dust cup 100, the dust baffle 300 is located between the filter element 200 and the bottom cover 120 and is connected to the bottom cover 120 or the filter element 200. In actual use, the airflow entering from the air inlet 130 is guided by the spiral duct 140 to flow along the spiral path within the dust cup 100. The airflow flows to the space between the bottom opening of the inner cover 160 and the dust baffle 300 and is drawn upward into the filter element 200. The dust and impurities in the airflow are carried to the bottom cover 120 under the action of centrifugal force. Since the dust baffle 300 is set between the filter element 200 and the bottom cover 120, most of the dust and impurities in the airflow are deposited on the bottom cover 120 and on the side of the dust baffle 300 facing the bottom cover 120. This effectively prevents dust and impurities from contacting the filter element 200, reduces dust accumulation on the surface of the filter element 200, reduces the risk of filter element 200 clogging, improves the suction efficiency and cleaning effect of the vacuum cleaner, extends the service life of the filter element 200, and reduces maintenance costs.

[0045] Optionally, such as Figure 2 and Figure 3 As shown, a first fixing rod 121 is provided on the side of the bottom cover 120 facing the dust cup 100. The dust baffle 300 is detachably connected to the end of the first fixing rod 121 away from the bottom cover 120, which allows for easy installation and removal of the dust baffle 300. This facilitates cleaning and maintenance of the dust cup 100, further enhancing the practicality and ease of use of the dust cup structure. Regular cleaning of the dust baffle 300 can effectively block dust and impurities from flowing from the area between the bottom cover 120 and the dust baffle 300 to the filter element 200, reducing clogging of the filter element 200, extending the service life of the filter element 200, and reducing maintenance costs.

[0046] Optionally, the dust baffle 300 can be snapped or threaded to the first fixing rod 121, which can ensure a stable connection between the dust baffle 300 and the first fixing rod 121, while also facilitating disassembly and assembly.

[0047] Optionally, a first mounting groove is provided on the first fixed rod 121, and a first locking hole is provided on the side wall of the first mounting groove. A first protrusion is provided on the dust baffle 300, and a first locking block is provided on the first protrusion. When the first protrusion is inserted into the first mounting groove, the first locking block is locked into the first locking hole to achieve a locking connection. The locking method has a simple structure, is quick to install and disassemble, and is suitable for scenarios with frequent cleaning.

[0048] In other implementations, the dust baffle 300 is provided with a first protrusion, the first protrusion is provided with a threaded hole, the first fixing rod 121 is provided with an external thread, the external thread of the first fixing rod 121 is threadedly engaged with the internal thread of the threaded hole to achieve a threaded connection. The threaded connection provides higher connection strength and ensures the stability of the dust baffle 300 under airflow impact.

[0049] Optionally, such as Figures 2-3 As shown, the inner wall of the dust cup 100 is provided with an air guide plate 150, which spirals from the air inlet 130 to the bottom cover 120 to form a spiral air duct 140. This effectively guides the airflow entering from the air inlet 130 along the spiral path. Utilizing centrifugal force, dust and impurities (such as lint) in the flow are deposited on the side of the dust baffle 300 facing the bottom cover 120, reducing dust accumulation on the surface of the filter element 200 and lowering the risk of filter element 200 clogging. This design simplifies the structure of the spiral air duct 140, reduces manufacturing difficulty, and enhances the stability of the airflow inside the dust cup 100.

[0050] Optionally, such as Figure 4 As shown, the filter element 200 includes an annular component 210, a frame 220, and a filter screen 230. The annular component 210 is fixed to one end of the dust cup 100 near the air outlet 110. The frame 220 protrudes from the side of the annular component 210 facing the dust cup 100. The frame 220 is circumferentially covered with the filter screen 230, which can increase the filtration area and improve the filtration effect.

[0051] Optionally, such as Figure 4 As shown, the axial section of the frame 220 is tapered, and the width of the tapered shape gradually increases along the direction from the bottom cover 120 to the air outlet 110, which allows the airflow to fully contact the filter screen 230, further improving the filtration effect. In addition, this design facilitates the smooth passage of airflow, reduces airflow resistance, further improves the suction efficiency of the vacuum cleaner, and enhances the dust collection effect.

[0052] Optionally, such as Figure 2 and Figure 3As shown, the dust cup 100 is equipped with an inner cover 160 integrally formed with the dust cup 100. The filter element 200 is placed inside the inner cover 160. When the airflow enters the dust cup 100 from the air inlet 130, the inner cover 160 isolates dust and impurities from the filter screen 230 on the filter element 200. After the airflow enters the dust cup 100, it flows in a ring around the outer wall of the inner cover 160. When it reaches the opening at the bottom of the inner cover 160 and the dust baffle 300, it is sucked into the filter element 200. Most of the dust and impurities are carried to the lower end of the dust baffle 300 under the action of centrifugal force and thus cannot be adsorbed on the filter screen. This results in low suction power loss, greatly saves the number of times the filter screen 230 and sponge need to be cleaned manually, and improves cleaning efficiency.

[0053] Optionally, such as Figure 2 and Figure 3 As shown, along the axial direction of the dust cup 100, the length of the spiral air duct 140 is less than the length of the inner cover 160. It can effectively guide the airflow in the initial stage of entering the dust cup 100, so that most of the dust and impurities are carried to the area between the bottom cover 120 and the dust baffle 300 under the action of centrifugal force. The airflow is directly output from the air outlet after passing through the filter element 200. This can avoid the air guide plate 150 blocking the airflow to the filter element 200, further reducing airflow resistance and improving the filtration effect and suction power of the vacuum cleaner.

[0054] Optionally, such as Figure 4 As shown, a first connecting part 122 and a second connecting part 124 are provided radially opposite to each other along the bottom cover 120. The first connecting part 122 is rotatably connected to the dust cup 100. A first latch 170 is provided at one end of the dust cup 100 near the bottom cover 120. The first latch 170 can be hooked onto the second connecting part 124 so that the bottom cover 120 and the dust cup 100 are relatively fixed. This can achieve reliable fixing and convenient opening and closing of the bottom cover 120 and the dust cup 100, making it convenient for users to clean the inside of the dust cup 100.

[0055] In this embodiment, the first connecting part 122 of the bottom cover 120 is elastically connected to the dust cup 100 through a torsion spring 123, which makes it easy for the bottom cover 120 to open automatically after the first latch 170 is unlocked, thus improving the convenience of cleaning.

[0056] Optionally, a protrusion is provided at the second connecting part 124, and the first latch 170 includes a first button 171 and a first spring 172. The middle part of the first button 171 is rotatably connected to the dust cup 100. One end of the first button 171 is provided with a first hook, and the other end is provided with a first spring 172 between it and the dust cup 100. The first spring 172 can drive the first hook of the first button 171 to hook onto the protrusion, thereby ensuring the stability of the connection between the bottom cover 120 and the dust cup 100.

[0057] Optionally, the dust cup structure also includes an electrostatic cotton ultrasonic component 400. The electrostatic cotton ultrasonic component 400 is located at the air outlet 110 of the dust cup 100 and can further capture residual fine dust and particles in the airflow using electrostatic adsorption, thereby further improving the filtration effect. It should be noted that the electrostatic cotton ultrasonic component 400 may include components such as sponge. The specific structure of the electrostatic cotton ultrasonic component 400 is prior art in this field, and its structure will not be described in detail.

[0058] Example 2

[0059] This embodiment provides a dust cup structure, which is basically the same as that of Embodiment 1, except that, as shown in Embodiment 1... Figure 5 As shown, a second fixing rod 240 is provided at one end of the filter element 200 near the bottom cover 120. The dust baffle 300 is detachably connected to the second fixing rod 240, which allows for easy installation and removal of the dust baffle 300. This facilitates the user's cleaning and maintenance of the dust baffle 300, further improving the convenience of dust cup structure maintenance. At the same time, regular cleaning of the dust baffle 300 can effectively block dust and impurities from flowing from the area between the bottom cover 120 and the dust baffle 300 to the filter element 200, reducing filter element 200 clogging, extending the service life of the filter element 200, and reducing maintenance costs.

[0060] Optionally, the dust baffle 300 can be snapped or threaded to the second fixing rod 240, which can ensure a stable connection between the dust baffle 300 and the second fixing rod 240, while also facilitating disassembly and assembly.

The dust baffle 300 is provided with a second protrusion 320, and the second protrusion 320 is provided with a second locking block 321. When the second protrusion 320 is inserted into the second mounting groove, the second locking block 321 is engaged in the second locking hole 241 to achieve a locking connection. The locking method has a simple structure, is quick to install and disassemble, and is suitable for scenarios with frequent cleaning.

[0062] In other implementations, the dust baffle 300 is provided with a second protrusion 320, the second protrusion 320 is provided with a threaded hole, the second fixing rod 240 is provided with an external thread, and the external thread of the second fixing rod 240 is threadedly engaged with the internal thread of the threaded hole to achieve a threaded connection. The threaded connection provides higher connection strength and ensures the stability of the dust baffle 300 under airflow impact.

[0063] Optionally, the dust baffle 300 has a conical surface 310 on the side near the filter element 200. In actual use, the spiral air duct 140 guides the airflow entering from the air inlet 130 to flow along the spiral path within the dust cup 100. The airflow is drawn upward into the filter element 200 between the bottom opening of the inner cover 160 and the dust baffle 300. At this time, the conical surface 310 can guide the airflow to flow quickly towards the filter element 200 and reduce airflow resistance. Dust and impurities in the airflow are carried to the bottom cover 120 under the action of centrifugal force. Since the dust baffle 300 is provided between the filter element 200 and the bottom cover 120, most of the dust and impurities in the airflow are deposited on the bottom cover 120 and on the side of the dust baffle 300 facing the bottom cover 120, effectively preventing dust and impurities from contacting the filter element 200, reducing dust accumulation on the surface of the filter element 200, reducing the risk of filter element 200 clogging, improving the suction efficiency and cleaning effect of the vacuum cleaner, extending the service life of the filter element 200, and reducing maintenance costs.

[0064] Example 3

By applying the aforementioned dust cup structure, dust accumulation on the surface of the filter element 200 can be reduced, lowering the risk of filter element 200 clogging and improving filtration efficiency. Furthermore, the detachable connection method facilitates user disassembly of the dust cup 100 for cleaning and maintenance, enhancing the ease of use and maintenance efficiency of the vacuum cleaner.

[0066] This vacuum cleaner significantly improves suction power and cleaning performance, extends the lifespan of the 200 filter, reduces maintenance costs, and enhances the reliability and user experience of the vacuum cleaner.

[0067] Optionally, such as Figure 4 As shown, the dust cup 100 is provided with a decorative cover 190, and the decorative cover 190 is provided with a second latch 180. The second latch 180 includes a second button 181 and a second spring 182. The first end of the second button 181 is rotatably connected to the decorative cover 190, and the second end of the second button 181 is provided with a second hook. The second spring 182 is provided between the second end of the second button 181 and the decorative cover 190.
