Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a dust cup structure of a vacuum cleaner. Background Art

[0002] For a vacuum cleaner, the dust cup plays a vital role. The vacuum cleaner uses strong suction to suck dust, debris, etc. into the body, and the dust cup is a container for collecting the sucked-in dust and garbage.

[0003] The existing dust cup structure consists of a cup body, a filter assembly, a filter HEPA, a bottom cover assembly and other components. Among them, the filter assembly consists of a filter mesh, a cyclone cone, and an ash pressing structure. The cup body is provided with an air inlet duct connected to its inner cavity. The filter HEPA is arranged on the upper part of the cup body, the filter assembly is arranged inside the cup body, and the bottom cover assembly is arranged at the bottom of the cup body. The rear end of the bottom cover is rotatably connected to the cup body, and the front end of the bottom cover is connected to the cup body through a release button.

[0004] The dirt is sucked into the air duct inside the main body by the dust-absorbing component, and enters the inner cavity of the dust cup through the air inlet duct; due to the setting of the air flow and the angle of the air inlet, the dirt is thrown out from the air inlet along the inner wall of the dust cup, and the heavy debris is finally settled to the bottom of the dust cup along the dust pressing structure set in the dust cup under the action of centrifugal force and gravity. After cleaning is completed, press the release button to make the front end of the bottom cover buckle and the button, and the bottom cover flips downward under the action of gravity, thereby achieving the purpose of one-button dumping.

[0005] However, when the above-mentioned dust cup structure is used to clean hair and flocculent debris, since the dust cup is provided with an air inlet filter connected to the inner cavity of the dust cup, hair and flocculent debris can easily stick to or accumulate on the outer wall of the air inlet filter and are not easy to clean. Users need to use their hands or use tools to complete the cleaning. Moreover, the filter assembly includes a dust pressing structure. Because the dust pressing structure is limited by the air inlet position of the dust cup, the dust needs to enter the lower part of the dust cup, so there is a gap between the dust cup and the inner wall of the dust cup. Therefore, the dust at the bottom will be brought back to the upper part of the dust cup by the airflow and then enter the interior of the vacuum cleaner through the filter, resulting in low separation efficiency of the dust cup (separation efficiency: the ratio of the amount of dust stored in the dust cup to the total amount of inhaled dust). Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and to provide a dust cup structure for a vacuum cleaner, which can not only provide guidance for falling dust through the spiral blades, but also prevent the dust below from turning up, thereby greatly improving the separation efficiency of the dust cup.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show components related to the present invention.

[0026] like Figure 1-Figure 2As shown, a dust cup structure of a vacuum cleaner includes a dust cup body 1, a bottom cover body 7, a dust pressing mechanism and a pop-up mechanism. The bottom cover body 7 is arranged at the bottom of the dust cup body 1 and can be flipped open and closed with it; the dust pressing mechanism is fixedly installed inside the dust cup body 1, and the pop-up mechanism is movably arranged on the dust pressing mechanism.

[0027] The dust cup body 1 is provided with an air inlet channel 11 connected to its inner cavity. The inner cavity adopts a cyclone separation structure, that is, the airflow entering the inner cavity through the air inlet channel 11 will be in the form of a cyclone, and the centrifugal force generated by the cyclone will be used to separate the dirt, and then the air is discharged from the top of the dust cup body 1; the dust pressing mechanism can prevent the dust at the bottom of the inner cavity from turning over, which greatly improves the separation efficiency of the dust cup, and the upper part of the pop-up mechanism is connected to the top of the inner cavity of the dust cup body 1, and the lower part is in contact with the bottom cover body 7 and can be popped out from the bottom end of the dust cup body 1, which can provide initial kinetic energy for the dumping of dirt, making it easier to detach from the inner cavity of the dust cup body 1 and dump out.

[0028] As mentioned above, the rear end of the bottom cover body 7 is rotatably connected to the dust cup body 1 through the rotating shaft 71, and the front end of the bottom cover body 7 is connected to the dust cup body 1 through the bottom cover release component 72; the front end of the bottom cover body 7 and the dust cup body 1 are snap-fitted, and the connection can be controlled by the bottom cover release component 72; when the front end of the bottom cover body 7 is released, the whole body will rotate and flip down around the rotating shaft 71 at the rear end, thereby opening the bottom of the dust cup body 1 and realizing the dumping of the garbage in the inner cavity.

[0029] Among them, the bottom cover body 7 can be flipped down under the action of its own gravity, and a torsion spring can also be installed on the rotating shaft 71, so that when the bottom cover body 7 is closed, a certain torsional potential energy is generated on the torsion spring, and the opening of the bottom cover body 7 is accelerated by this potential energy; and the bottom cover release component 72 here adopts mature existing technology, so no further details will be given here.

[0030] Example 1

[0031] like Figure 1 As shown, the ash pressing mechanism includes an ash pressing bracket 5 and a spiral blade 51. The spiral blade 51 is located below the air inlet channel 11. The ash pressing bracket 5 adopts a cylindrical structure, and its outer side is connected to the inner wall of the dust cup body 1 through the spiral blade 51. The spiral blade 51 is spiral along the axis of the dust cup body 1, and the ash pressing bracket 5 and the spiral blade 51 are both coaxially distributed with the dust cup body 1.

[0032] The radial ends of the spiral piece 51 are respectively fixedly connected to the outer side surface of the dust pressing bracket 5 and the inner side surface of the dust cup body 1, so the inner cavity is divided into two layers, and the pop-up mechanism is arranged inside the dust pressing bracket 5, which can ensure that when the bottom cover body 7 and the dust cup body 1 are closed, there is only a spiral channel connecting the upper and lower layers of the inner cavity; based on this, when the vacuum cleaner is working, dust and other debris enter the upper layer of the inner cavity along the air inlet channel 11 under the influence of the air flow, and after being separated from the air, dust and other debris enter the lower layer along the spiral channel, and due to the structural limitation of the spiral piece 51, even if there is air flow entering the lower layer of the inner cavity to stir the dust, it will not be turned up into the upper space.

[0033] In summary, the spiral blade 51 can not only provide guidance for the falling dust, but also prevent the dust at the bottom of the inner cavity from turning up, thereby greatly improving the separation efficiency of the dust cup.

[0034] Example 2

[0035] On the basis of the first embodiment, the present invention further proposes a related structure of a pop-up mechanism.

[0036] like Figure 1-Figure 3 As shown, the pop-up mechanism includes a channel bracket 2, a cyclone upper cover 3, an air inlet filter 4, a cyclone cone 8 and an elastic member 13. The channel bracket 2 is fixedly installed on the top of the inner cavity of the dust cup main body 1, and an air outlet channel 21 is opened on the inner side thereof. The cyclone upper cover 3 is provided on the outer sliding sleeve, and the elastic member 13 is located between the upper end of the cyclone upper cover 3 and the root of the channel bracket 2. The cyclone cone 8 is fixedly installed on the lower end of the cyclone upper cover 3; the bottom cover body 7 is in a closed state, abutting against the lower end of the cyclone cone 8, and causing the elastic member 13 to be compressed and shortened.

[0037] Among them, the cyclone cone 8 and the cyclone cover 3 are arranged on the inner side of the ash pressing bracket 5, and both of them and the channel bracket 2 are coaxial with the ash pressing bracket 5. The air inlet filter 4 is fixedly installed on the outer side of the cyclone cover 3, and the cyclone airflow entering the inner cavity can pass through the air inlet filter 4 and the cyclone cover 3 and be discharged along the air outlet channel 21.

[0038] The cyclone cone 8 is connected to a top rod 81 , and an ash pressing plate 82 is sleeved on the outer side of the top rod 81 . The ash pressing plate 82 can move synchronously with the cyclone cone 8 , the top rod 81 and the cyclone upper cover 3 .

[0039] When the bottom cover body 7 is closed, the bottom cover body 7 abuts against the lower end of the top rod 81, and the ash pressing plate 82 abuts against the lower end of the ash pressing bracket 5, thereby ensuring that the upper and lower layers of the inner cavity are connected only through the spiral channel. At this time, the cyclone upper cover 3 is located in the upper layer of the inner cavity and is sleeved on the outside of the channel bracket 2, so that the elastic part 13 is compressed to store elastic potential energy, and the elastic force acts on the bottom cover body 7.

[0040] When the bottom cover body 7 is opened, the top rod 81 loses its support from below. Under the elastic force of the elastic member 13, the cyclone upper cover 3, the air inlet filter 4, the cyclone cone 8 and the top rod 81 move downward relative to the dust pressing bracket 5 and the dust cup body 1, providing initial kinetic energy for the dumping of dirt, making it easier for the dirt to escape from the dust cup cavity and dump out.

[0041] Sealing rings 9 are provided on the inner side of the upper end of the ash pressing bracket 5 and the top of the inner cavity; when the bottom cover body 7 is closed, the cyclone upper cover 3 moves up to the top of the inner cavity and is squeezed between the sealing ring 9 to ensure sealing. In the process of the cyclone upper cover 3 moving down, the sealing ring 9 on the inner side of the upper end of the ash pressing bracket 5 is always in contact with the air inlet filter 4 to remove the dirt remaining on the outer wall of the filter.

[0042] Similarly, a sealing ring 9 is also provided on the bottom cover body 7 at a position corresponding to the push rod 81 .

[0043] Regarding the installation of the ash pressing plate 82, a card slot 84 is provided on it, and a rotary buckle 83 corresponding to the card slot 84 is provided on the outer side of the top rod 81. It is only necessary to put the ash pressing plate 82 into place and then rotate the ash pressing plate 82 so that the rotary buckle 83 is stuck in the card slot 84 to achieve a fixed connection. It is not only firm and reliable, but also convenient for disassembly and assembly.

[0044] Regarding the elastic member 13, a spring is preferably used and is mounted on the outside of the channel bracket 2; a first storage groove 22 is opened at the root of the channel bracket 2, and a second storage groove 32 corresponding to the first storage groove 22 is opened on the upper part of the cyclone cover 3, and the two ends of the elastic member 13 are respectively embedded in the first storage groove 22 and the second storage groove 32; this can prevent the position of the elastic member 13 from being shifted during the opening and closing process of the bottom cover body 7.

[0045] An installation groove for installing the air inlet filter 4 is also provided on the outer circumferential surface of the cyclone cover 3. During installation, the air inlet filter 4 is put on the outer side of the cyclone cover 3 from bottom to top, and then the cyclone cone 8 is fixed to the bottom of the cyclone cover 3 as a support to ensure that the air inlet filter 4 is stable and reliable during operation.

[0046] In order to ensure that the lower part of the pop-up mechanism can be stably popped out and retracted relative to the upper part, a guide protrusion 31 is provided on the inner side of the cyclone cover 3, and a sliding groove corresponding to the guide protrusion 31 is opened on the outer side of the channel bracket 2. The lower end of the sliding groove is a closed end, and one end of the guide protrusion 31 is slidably embedded in the sliding groove; this structure can not only provide guidance for the movement of the cyclone cover 3, but also limit the movement range of the cyclone cover 3, thereby avoiding the situation where the upper and lower parts of the pop-up mechanism are completely separated.

[0047] In addition, a filter assembly 6 for filtering air is installed on the top of the dust cup body 1. The lower end of the filter assembly 6 is connected to the air outlet channel 21, and a dust cup release assembly 12 is also provided on the outside of the top of the dust cup body 1. Its function is similar to that of the bottom cover release assembly 72, and is used to realize the connection and release between the dust cup structure and the vacuum cleaner host.

[0048] The filter assembly 6 includes a HEPA frame, which is installed on the top of the outer side of the dust cup body 1, and the interior of the HEPA frame is filled with HEPA and other filter materials. The lower end of the HEPA frame is connected to the air outlet channel 21, and the upper end is connected to the air inlet of the vacuum motor. Its purpose is to filter out fine impurities in the air and ensure that the discharged air will not cause secondary pollution to the environment.

[0049] (1) Normal working state: At this time, the dust cup structure is in the closed state, the pop-up mechanism is close to the side of the hepa frame, and is pressed with the sealing ring 9 set on the top of the dust cup cavity to form an effective seal; the air inlet set on the back of the hepa frame is sealed and connected with the main body; the dirt is sucked into the air duct inside the body by the dust-absorbing component of the main body, and enters the cyclone through the air inlet of the dust cup structure (the inner and outer ends of the air inlet channel 11 are the cyclone and the air inlet respectively). At this time, the dust shield is pushed open by the air flow, and the dirt enters the inner cavity; due to the air flow and the angle setting of the cyclone, the dirt is thrown out from the cyclone along the inner wall of the dust cup, and the heavy debris is affected by the centrifugal force Due to the action of gravity, the dust is finally settled to the bottom of the dust cup along the dust pressing mechanism in the dust cup, while the hair, flocs, dust and other small debris are pulled by centrifugal force and the upward airflow and rise to the air inlet filter 4 side of the pop-up mechanism. The small hair and flocs are gradually stopped from moving due to the resistance of the dust pressing plate 82 in the dust cup and gather downward. The air inlet filter 4 realizes the first filtration, and the dirt mixed with fine particles and hair passes through the composite filter cotton and electrostatic cotton of the HEPA component in turn under the drive of the airflow, thereby realizing the second and third filtration. The filtered clean air is finally discharged into the room.

[0050] As small debris such as hair, flocculent debris, and dust are continuously sucked in, the dirt is continuously gathered by the pulling force of the upward airflow and the resistance of the dust pressing plate 82, and as the airflow continues to flow, the dirt is compressed.

[0051] At the same time, the dust pressing plate 82 also plays the role of supporting the compressed dirt away from the surface of the air inlet filter 4, ensuring that a certain air flow cross-section is always left on the air inlet side of the air inlet filter 4, ensuring smooth airflow, improving the dirt compression effect and the effective volume of the dust cup cavity, while also avoiding the main unit from shutting down or malfunctioning due to poor airflow, heat generation, and other problems.

[0052] After the main unit stops working, the dust shield set on the cyclone outlet side is closed. At this time, the dust cup structure forms a closed cavity. The user can remove the dust cup structure from the main unit for dumping or cleaning.

[0053] (2) The dust cup assembly is tilted: the user holds the dust cup body 1 with one hand and pushes the push rod of the bottom cover release assembly 72 with the other hand. The push rod spring is compressed under pressure, pushing the push rod to the bottom to cause the front end of the bottom cover body 7 to disengage from the engaged position. The bottom cover body 7 is tilted by gravity to a certain angle and is separated from the lower end face of the pop-up mechanism. At this time, the elastic member 13 in the pop-up mechanism is deformed, and the cyclone cover 3 of the pop-up mechanism is pressed axially outward from the dust cup cavity. The bottom cover body 7 continues to tilt downward under the action of gravity and the elastic force of the pop-up mechanism. At the same time, the accumulated or compressed dirt slides down a distance along the lower part of the pop-up mechanism under the action of the elastic potential energy brought by the pop-up mechanism. The pop-up mechanism stops sliding down due to the resistance of the limiting structure. The dirt accelerates downward under the dual action of inertia and gravity until it falls outside the dust cup cavity; the sealing ring 9 fixed on the inner side of the dust pressing bracket 5 is always in contact with the outer wall of the air inlet filter 4 during the movement of the cyclone cover 3 to remove the dirt remaining on the outer wall of the filter.

[0054] The dumping process of the dust cup structure described above truly realizes the purpose of dumping with one-touch release and realizes the function of cleaning the outer wall of the air inlet filter 4 during the dumping process.

[0055] To sum up, the dust cup structure of the present invention is technically improved and upgraded specifically for the situation where hair and flocculent debris are easily adhered and dirt is not completely dumped out, so as to avoid the phenomenon that users need to use their hands or tools to clean thoroughly due to incomplete dumping. While releasing the dumping with one button, it can effectively clean the hair, dust and other dirt remaining on the inner wall of the dust cup cavity, increase the effective volume of the dust cup, reduce the frequency of user cleaning, and truly achieve the purpose of one-button release dumping and the function of cleaning the inner wall of the dust cup during the dumping process; make cleaning more convenient, save time and effort, and thus improve user experience.

[0056] In addition, in order to address the problem that hair and floc-like debris are easily stuck together and dirt is accumulated and carried into the upper part of the dust cup by the rising airflow, a spiral blade 51 spiraling downward is provided inside the dust cup to provide guidance for the deposition of dirt while preventing dust from being carried into the upper part of the dust cup by the rising airflow. This truly improves the dust cup separation efficiency and enhances the performance of the vacuum cleaner, thereby enhancing the user experience.
