Description
Technical Field
[0001] This invention relates to the field of household appliance technology, and in particular to vacuum cleaners and cleaning equipment. Background Technology
[0002] With advancements in technology and improvements in living standards, cleaning equipment such as vacuum cleaners and floor scrubbers have become commonplace in households, bringing great convenience to people's lives. These devices typically have a dust cup to collect inhaled dust and other dirt. When the dust cup is full, it needs to be emptied. Currently, many cleaning devices offer two common methods for emptying the dust cup: one is to detach the entire dust cup from the cleaning device before emptying, and the other is to move the dust cup relative to the main body of the cleaning device until its opening is exposed, allowing the dirt to pour out. However, the first method requires detaching the dust cup, which is cumbersome. While the second method doesn't require detaching the dust cup, once the opening is exposed, the dirt will immediately pour out. If the dust cup hasn't reached its final position, some dirt will spill out with the movement and won't all fall into the trash can. Summary of the Invention
[0003] Based on this, the present invention proposes a vacuum cleaner device in which the dust cup does not need to be removed when the dirt needs to be emptied, making the operation more convenient. Furthermore, the dirt in the dust cup will not spill out when the dust cup is in motion, and can all fall into the area to be emptied, such as a trash can.
[0004] Vacuum cleaning device, including:
[0005] case;
[0006] A dust cup assembly, comprising a dust cup and a dust cup mounting component, wherein the dust cup comprises a dust cup body and a dust cup cover, the dust cup mounting component is connected to the housing, the dust cup is rotatably connected to the dust cup mounting component, and the dust cup body is provided with a pouring port communicating with the receiving cavity of the dust cup body;
[0007] A first locking component is connected to the housing; in the locked state, the dust cup is locked inside the housing by the first locking component; in the released state, the dust cup is separated from the first locking component, and the dust cup can rotate relative to the dust cup mounting member to the released position.
[0008] The second locking component is connected to the dust cup body. The dust cup cover can be locked in the closed position by the second locking component to block the pouring port. When the dust cup is in the released position, the second locking component can separate from the dust cup cover under the action of external force to open the pouring port.
[0009] In one embodiment, in the locked state, the second locking component is located in the cavity formed by the housing; when the dust cup is in the released position, the second locking component is exposed.
[0010] In one embodiment, in the released state, the dust cup assembly is located on the side of the vacuuming device closer to the area to be emptied, and when the dust cup is in the released position, the emptying port is located at the bottom end of the dust cup body.
[0011] In one embodiment, the direction of the external force applied to the second locking component is perpendicular to the first direction, with the rotation trajectory of the dust cup between the locked state and the released state being the tangent of the rotation trajectory at the released position as the first direction.
[0012] In one embodiment, the dust cup cover is rotatably connected to the dust cup body. When the dust cup is in the released position, the second locking component can be separated from the dust cup cover under the action of external force, and the dust cup cover rotates downward relative to the dust cup body to the open position.
[0013] In one embodiment, the second locking component includes a first hook-on portion, and the dust cup cover includes a second hook-on portion. The first hook-on portion can hook onto the second hook-on portion to lock the dust cup cover in the closed position. When the dust cup is in the released position, the first hook-on portion can be separated from the second hook-on portion under the action of an external force.
[0014] In one embodiment, the second locking component includes a second operating button, a third elastic element, and a second locking component housing. The second operating button is provided with the first hook portion. The second locking component housing is fixedly connected to the dust cup body. The third elastic element is connected between the second operating button and the second locking component housing. The second operating button can move to the point where the first hook portion and the second hook portion are separated under the action of an external force. The third elastic element is used to drive the second operating button to reset after the external force applied to the second operating button is removed.
[0015] In one embodiment, the second operating button is rotatably connected to the second locking component housing. The second operating button includes a second operating button pressing portion for receiving external force. The second operating button pressing portion is located at one end of the second operating button away from the first hook portion. The second operating button can rotate relative to the second locking component housing under the action of external force until the first hook portion and the second hook portion are separated.
[0016] In one embodiment, the first locking component includes a first latching portion, and the dust cup body includes a second latching portion. In the locked state, the first latching portion and the second latching portion are latched together, and in the released state, the first latching portion and the second latching portion are separated.
[0017] In one embodiment, the first locking assembly includes a first operating button, a connecting rod, and a first elastic element. The connecting rod is provided with a first latching portion. The first operating button is mounted on the housing and is located at one end of the connecting rod away from the first latching portion. The first elastic element connects the connecting rod and the housing. The first operating button can press the connecting rod under external force to rotate the connecting rod until the first latching portion and the second latching portion are separated. The first elastic element is used to drive the connecting rod to return to the locked state after the external force applied to the first operating button is removed.
[0018] In one embodiment, the direction of the external force applied to the first operating button is perpendicular to the direction in which the first operating button presses the connecting rod. The first operating button includes a protrusion protruding relative to the body. The protrusion includes a first inclined surface. The end of the connecting rod away from the first latching portion includes a second inclined surface. The first operating button can move toward the connecting rod under the action of the external force so that the second inclined surface gradually fits into different areas of the first inclined surface. Along the direction of the external force, the size of the protrusion gradually decreases in the pressing direction.
[0019] In one embodiment, a second elastic member is further included, which is connected between the dust cup body and the dust cup mounting member. The second elastic member is used to drive the dust cup to rotate relative to the dust cup mounting member to the release position after the first snap-fit portion separates from the second snap-fit portion.
[0020] In one embodiment, the housing is provided with a receiving groove. In the locked state, the dust cup is locked in the receiving groove by the first locking component. One end of the dust cup away from the rotatable connection between the dust cup body and the dust cup mounting component engages with the inclined wall of the receiving groove to avoid positional movement when the dust cup rotates relative to the receiving groove.
[0021] In one embodiment, the vacuuming device further includes a third locking component connected to the housing. In the locked state, the dust cup mounting component is locked to the housing by the third locking component; in the released state, the dust cup mounting component is detachably connected to the third locking component.
[0022] In one embodiment, the third locking component includes a third operating button with a third latching portion, the dust cup mounting component includes a fourth latching portion, and a fourth elastic member is connected between the third operating button and the housing. The third latching portion can engage with the fourth latching portion to lock the dust cup component to the housing. In the released state, the third operating button can move under the action of an external force until the third latching portion separates from the fourth latching portion. The fourth elastic member is used to drive the third operating button to reset after the external force applied to the third operating button is removed.
[0023] In one embodiment, the third operating button has a third operating button pressing part at one end away from the third locking part for receiving external force. In the released state, the third operating button can rotate under the action of external force until the third locking part separates from the fourth locking part.
[0024] In one embodiment, a motor is installed inside the housing, an intake port is provided at the end of the housing, an air duct communicating with the intake port is provided inside the housing, a dust cup assembly is installed in the air duct, the motor and the dust cup assembly are arranged along the axial direction of the dust collection device, a filter is installed in the receiving cavity, the airflow entering from the intake port is filtered by the filter and flows through the motor, and is discharged from the outlet provided in the housing.
[0025] In one embodiment, in the released state, the filter rotates synchronously with the dust cup to the released position.
[0026] In one embodiment, the vacuuming device further includes a battery removably mounted within the housing.
[0027] The aforementioned vacuum cleaner includes a housing, a dust cup assembly, a first locking assembly, and a second locking assembly. The dust cup mounting component is connected to the housing, and the dust cup body is rotatably connected to the dust cup mounting component. The dust cup body has a pouring port communicating with its receiving cavity. In the locked state, the dust cup is locked within the housing by the first locking assembly. In the released state, the dust cup separates from the first locking assembly, and the dust cup can rotate relative to the dust cup mounting component to the released position. When the dust cup is in the released position, the second locking assembly can separate from the dust cup cover under external force to open the pouring port and empty the dust and other contaminants from the receiving cavity. In this vacuum cleaner, simply unlocking the first locking assembly, rotating the dust cup relative to the dust cup mounting component to the released position, and applying external force to unlock the second locking assembly, so that the dust cup cover no longer blocks the pouring port, allows the dust and other contaminants in the receiving cavity to be emptied. In this process, simply rotate the dust cup to the tilting position and open the dust cup cover to tilt it. There is no need to remove the dust cup from the housing, making the operation more convenient. Furthermore, the dust cup cover can only be separated from the second locking component when the dust cup is in the tilting position. During the rotation of the dust cup from the locked state to the released state, the dust in the containment cavity will not spill out into the area to be emptied, such as areas other than the trash can, because the tilting port is blocked by the dust cup cover.
[0028] The present invention proposes a cleaning device, including the above-mentioned vacuuming device.
[0029] In one embodiment, the cleaning equipment is a vacuum cleaner or a floor scrubber.
[0030] In one embodiment, if the cleaning equipment is a floor scrubber, the floor scrubber includes a floor brush assembly, a body, a waste liquid tank and a cleaning liquid tank. The vacuuming device and the floor brush assembly are respectively connected to both ends of the body. The waste liquid tank is installed on the body, the cleaning liquid tank is installed on the floor brush assembly, and the suction port is located on the vacuuming device near the end of the body.
[0031] The aforementioned cleaning equipment, by using the aforementioned vacuuming device, eliminates the need to remove the dust cup when emptying the waste, making operation more convenient. Furthermore, the waste inside the dust cup will not spill out during the movement of the dust cup, but will all fall into the area to be disposed of, such as a trash can. Attached Figure Description

[0055] See Figure 1 and Figure 2 One embodiment of the present invention provides a cleaning device including a vacuum cleaner 10. The vacuum cleaner 10 provides suction power during operation and filters and collects dust and other dirt, ensuring that the airflow exiting the cleaning device is clean air. In some embodiments, the cleaning device can be a vacuum cleaner. In other embodiments, the cleaning device can be a floor scrubber. Figure 1 In the embodiments shown, the cleaning equipment is a floor scrubber. For ease of description and understanding, the following embodiments will use a floor scrubber as an example to introduce the cleaning equipment and the vacuuming device 10 therein.
[0056] See Figure 1 and Figure 2 In some embodiments, the floor scrubber includes a floor brush assembly 700, a body 800, a waste liquid tank 810, and a cleaning liquid tank 710. The vacuuming device 10 and the floor brush assembly 700 are respectively connected to both ends of the body 800. The waste liquid tank 810 is installed on the body 800, the cleaning liquid tank 710 is installed on the floor brush assembly 700, and the suction inlet 130 is located on the vacuuming device near the end of the body 800. Specifically, in Figure 1 At the angle shown, the floor brush assembly 700 is connected to the bottom of the body 800, and the vacuuming device 10 is connected to the top of the body 800. The floor brush assembly 700 is in contact with the area to be cleaned, which can be the floor. The cleaning fluid tank 710 stores liquids such as water and / or cleaning agent, and the waste fluid tank 810 is used to store the cleaning fluid mixed with dust and other dirt that is recovered after cleaning the floor.
[0057] See Figure 1 , Figure 2 and Figure 5In some embodiments, a motor 610 is installed inside the housing 100 of the vacuum cleaner 10. An intake port 130 is located at the end of the housing 100 near the body 800. An air duct 120 communicating with the intake port 130 is located inside the housing 100. A dust cup assembly is installed near the outlet of the air duct 120. The motor 610 and the dust cup assembly are arranged axially along the vacuum cleaner 10. A filter 240 is installed inside the dust cup assembly. Airflow entering from the intake port 130 is filtered by the filter 240, flows through the motor 610, and is discharged from the outlet 140 located in the housing 100. Specifically, a pipe communicating with the suction port of the floor brush assembly 700 is located inside the body 800, and this pipe is also connected to the intake port 130. When the floor scrubber is working, the motor 610 runs to provide suction power. The cleaning liquid in the cleaning liquid tank 710 is sprayed onto the ground. The floor brush in the floor brush assembly 700 absorbs the cleaning liquid and rubs against the ground to remove stains. After the cleaning liquid absorbs dust, hair and other dirt, it becomes waste liquid. The waste liquid is squeezed by a pressure plate on one side of the floor brush. The squeezed waste liquid is drawn upwards into the pipe inside the machine body 800 and transported to the waste liquid tank 810. A gas-liquid separator is installed in the waste liquid tank 810 to separate the mixed fluids. Most of the dust dissolves in the cleaning liquid and remains in the waste liquid tank 810. The airflow mixed with a small amount of dust continues to flow upwards and enters the air duct 120 from the suction port 130, and then enters the dust cup assembly. The filter 240 in the dust cup assembly filters the airflow mixed with a small amount of dust. After filtration, the clean airflow flows through the motor 610 and is discharged from the discharge port 140. The filtered dust and other particles are retained in the dust cup assembly. The scraper structure at the floor brush assembly 700 and the gas-liquid separator at the waste liquid tank 810 can both be achieved using existing technologies, and will not be described in detail here.
[0058] Of course, the vacuum cleaner 10 can also be detached from the main body 800 and used independently, making it suitable for a wide range of applications. The vacuum cleaner 10 can be used alone to clean areas such as sofas or beds. When the motor 610 is running, dust and other particles are sucked in through the suction port 130 and flow into the dust cup assembly through the air duct 120. The filter 240 inside the dust cup assembly filters the airflow mixed with dust. The filtered clean airflow then flows through the motor 610 and is discharged from the exhaust port 140. The filtered dust and small particles are retained in the dust cup assembly.
[0059] See Figures 1 to 3 In some embodiments, the vacuum cleaner 10 includes a battery 620 detachably mounted within the housing 100. Specifically, the battery 620 is mounted on the end of the housing 100 away from the suction inlet 130, and the battery 620 powers the motor 610, enabling the motor 610 to operate and provide suction. When the battery is low, the battery 620 can be removed for charging, or a fully charged battery can be replaced. The battery 620 and the housing 100 can be mounted using a detachable structure as in the prior art, such as by means of elastic snap-fit or interference fit.
[0060] The following embodiments describe the structure of the vacuuming device 10.
[0061] See Figures 2 to 5 In some embodiments, the vacuum cleaner 10 includes a housing 100, a dust cup assembly, a first locking assembly 300, and a second locking assembly 400, with the first locking assembly 300 connected to the housing 100. The dust cup assembly includes a dust cup 210 and a dust cup mounting member 220, which is connected to the housing 100 and rotatably connected. Specifically, the dust cup body 211 is rotatably connected to the dust cup mounting member 220. The dust cup 210 includes a dust cup body 211 and a dust cup cover 212. The dust cup body 211 has a pouring port 2112 communicating with the receiving cavity 2111 of the dust cup body 211. The receiving cavity 2111 of the dust cup body 211 is used to contain dust and other dirt, and the dirt in the receiving cavity 2111 can be poured out through the pouring port 2112. Figure 2 In the locked state, the dust cup 210 is locked within the housing 100 by the first locking component 300; in the released state, the dust cup 210 is separated from the first locking component 300, and the dust cup 210 can rotate relative to the dust cup mounting member 220. Figure 4 The release position is shown. The second locking component 400 is connected to the dust cup body 211, and the dust cup cover 212 can be locked in the closed position by the second locking component 400. At this time, the dust cup cover 212 blocks the pouring port 2112, and the dirt in the receiving cavity 2111 cannot be poured out. When the dust cup 210 is in the release position, the second locking component 400 can be separated from the dust cup cover 212 under the action of external force. The dust cup cover 212 is no longer locked in the closed position by the second locking component 400, so it no longer blocks the pouring port 2112, and the dirt in the receiving cavity 2111 can be poured out through the pouring port 2112.
[0062] In the aforementioned vacuuming device 10, simply unlocking the first locking component 300 allows the dust cup 210 to rotate relative to the dust cup mounting component 220 to the release position, and applying external force to unlock the second locking component 400, so that the dust cup cover 212 no longer blocks the pouring opening 2112, allowing the dust and other dirt in the receiving cavity 2111 to be poured out. During this process, simply rotating the dust cup 210 to the pouring position and opening the dust cup cover 212 is sufficient for pouring; there is no need to remove the dust cup 210 from the housing 100, making operation more convenient. Furthermore, the dust cup cover 212 can only separate from the second locking component 400 when the dust cup 210 is in the pouring position. During the rotation of the dust cup 210 from the locked state to the release state, because the pouring opening 2112 is blocked by the dust cup cover 212, the dust and other debris in the receiving cavity 2111 will not spill out from the pouring opening 2112 into the area to be poured out, such as areas other than the trash can. In addition, the dust cup cover 212 can be opened only after the dust cup 210 has stably reached the release position and stopped shaking, so as to ensure that the dust in the receiving cavity 2111 can be poured into the trash can more accurately.
[0063] See Figures 4 to 7 In some embodiments, the first locking component 300 includes a first latching portion 321, and the dust cup body 211 includes a second latching portion 2113. In the locked state, the first latching portion 321 and the second latching portion 2113 are latched together; in the released state, the first latching portion 321 and the second latching portion 2113 are separated. Specifically, one of the first latching portion 321 and the second latching portion 2113 can be a hook, and the other can be a slot. For example, in the embodiment shown in the attached figure, the first latching portion 321 is a hook, and the second latching portion 2113 is a slot. In other embodiments, the slot and the hook can also be interchanged. When the hook engages the slot, the position of the dust cup body 211 is locked and cannot be rotated. When the hook exits from the slot, the dust cup body 211 can rotate to reach the released position. Of course, in addition to locking by latching, conventional methods such as plugging or magnetic fixation can also be used.
[0064] Specifically, in some embodiments, the first locking assembly 300 includes a first operating button 310, a connecting rod 320, and a first elastic member (not shown in the figure). The connecting rod 320 is provided with a first engaging portion 321. The first operating button 310 is mounted on the housing 100 and is located at the end of the connecting rod 320 away from the first engaging portion 321. The first elastic member connects the connecting rod 320 and the housing 100. The first operating button 310 can press the connecting rod 320 under external force to rotate the connecting rod 320 until the first engaging portion 321 separates from the second engaging portion 2113. The first elastic member is used to drive the connecting rod 320 to reset to the locked state after the external force applied to the first operating button 310 is removed. Specifically, the connecting rod 320 is equivalent to a lever. By pressing one end of the connecting rod 320 with the first operating button 310, the other end with the first engaging portion 321 is raised, thereby separating from the second engaging portion 2113. Alternatively, in some embodiments, the first operating button 310 and the connecting rod 320 can be integrated into one unit. Or, in other embodiments, the first operating button 310 can be omitted, and the external force acts directly on the end of the connecting rod 320 away from the first locking portion 321. The connecting rod 320 is provided with a protruding rotating shaft 323, which is integrated with the main body of the connecting rod 320. A groove matching the size of the rotating shaft 323 is provided at a corresponding position on the housing 100. The rotating shaft 323 is placed in the groove, and when an external force is applied, the rotating shaft 323 rotates within the groove. Preferably, the rotating shaft 323 is located in the region of the connecting rod 320 close to the first locking portion 321 along its length direction; that is, the connecting rod 320 is a force-saving lever, requiring only a small external force to separate the first locking portion 321 from the second locking portion 2113.
[0065] Further, in some embodiments, the direction of the external force applied to the first operating button 310 is perpendicular to the direction in which the first operating button 310 presses the connecting rod 320. The first operating button 310 includes a protrusion 311 protruding relative to the main body, the protrusion 311 including a first inclined surface 3111, and the end of the connecting rod 320 away from the first engaging portion 321 including a second inclined surface 322. The first operating button 310 can move toward the connecting rod 320 under the action of external force, so that the second inclined surface 322 gradually conforms to different areas of the first inclined surface 3111. Along the direction of external force, the size of the protrusion 311 in the pressing direction gradually decreases. Specifically, the first operating button 310 is a push button. Figure 7At the specified angle, when the push button is pushed to the left by an external force, the first inclined surface 3111 on the push button continuously presses down against the second inclined surface 322, causing the left end of the connecting rod 320 to tilt upwards, and the latch to disengage from the slot. The aforementioned first elastic element can be a spring, which is located between the left end of the connecting rod 320 and the housing 100. When the left end of the connecting rod 320 tilts upwards, the spring is compressed. When the external force applied to the push button is removed, the spring's rebound force drives the left end of the connecting rod 320 to move downwards, the latch re-engages into the slot, and the right end of the connecting rod 320 tilts upwards, pushing the push button to the right and resetting it. Of course, the first operating button 310 can also be a button. By pressing the left end of the button, the right end of the connecting rod 320 is pressed downwards, and the left end tilts upwards.
[0066] exist Figure 5 and Figure 7 From a viewing angle, in the locked state, the axis of the dust cup 210 is parallel to the axis of the housing 100. When the hook separates from the slot, the dust cup 210 rotates downwards by 90 degrees to reach the release position. Therefore, in some embodiments, when it is necessary to release the dust cup 210, the vacuuming device 10 can be in the [position not specified]. Figure 4 When placed flat or nearly flat, the dust cup 210 will automatically rotate downwards under its own weight and the weight of the dust after the first locking part 321 separates from the second locking part 2113.
[0067] Preferably, in some embodiments, a second elastic element 230 is further included. The second elastic element 230 is connected between the dust cup body 211 and the dust cup mounting member 220. The second elastic element 230 is used to drive the dust cup 210 to rotate relative to the dust cup mounting member 220 to the release position after the first locking portion 321 separates from the second locking portion 2113. By providing the second elastic element, the release force of the dust cup 210 can be increased, allowing it to quickly reach the release position. Additionally, if the dust cup 210 assembly does not... Figure 4 Release at the indicated angle or a similar angle, for example, if the dust cup 210 is located at the indicated angle during release. Figure 4 At the angle shown, on the upper side, where the dust cup 210 and the first locking component 300 are on the same side, automatic release by gravity is not possible. It requires a drive from the second elastic element 230, and the driving force must be greater than the weight of the dust cup 210 to make it spring upwards. Specifically, the second elastic element 230 is a torsion spring. When the dust cup 210 is in the locked state, the torsion spring is in a deformed state. When the hook separates from the slot, the spring's rebound force drives the dust cup 210 to rotate outwards, thus reaching the release position. Figure 4 and Figure 7From this perspective, when the hook separates from the slot, the rebound force of the torsion spring drives the dust cup 210 to rotate downwards by 90 degrees, reaching the release position. Of course, the rotation angle is not limited to 90 degrees; other angles are also possible. To relock the dust cup 210, simply rotate the dust cup 210 in the opposite direction using external force and operate the first operating button 310 again, causing the first engaging part 321 to lift and move away from the dust cup 210. After the dust cup 210 rotates to the locked position, release the first operating button 310, and the first engaging part 321 will engage with the second engaging part 2113 again to achieve locking.
[0068] See Figures 5 to 7 In some embodiments, the housing 100 is provided with a receiving groove 110. In the locked state, the dust cup 210 is locked in the receiving groove 110 by the first locking component 300. One end of the dust cup 210 away from the rotatable connection between the dust cup body 211 and the dust cup mounting component 220 engages with the inclined surface of the groove wall of the receiving groove 110 to avoid positional movement when the dust cup 210 rotates relative to the receiving groove 110. Specifically, at the angle shown in the attached figure, that is, the left end of the dust cup 210 is inclined, and the dust cup 210 is shorter at the top and longer at the bottom. Correspondingly, the receiving groove 110 is also shorter at the top and longer at the bottom. When the dust cup 210 is removed from the receiving groove 110, and when the dust cup 210 is reset and re-enters the receiving groove 110, the left end of the dust cup 210 will not collide with the left end of the receiving groove 110. Specifically, the dust cup cover 212 of the dust cup 210 is installed on the left end of the dust cup body 211, and most of the outer wall of the dust cup cover 212 is inclined.
[0069] See Figures 4 to 6 In some embodiments, in the locked state, the second locking component 400 is located within the cavity formed by the housing 100; when the dust cup 210 is in the released position, the second locking component 400 is exposed. Therefore, when the dust cup 210 is not released, the operator cannot touch the second locking component 400; only by releasing the dust cup 210 can the second locking component 400 be operated. This avoids the dust cup cover 212 opening and dust being poured out due to accidental triggering of the second locking component 400 while the vacuum cleaner 10 is operating. Specifically, in the locked state, both the second locking component 400 and the dust cup cover 212 are located inside the housing 100; when the dust cup 210 is in the released position, both the second locking component 400 and the dust cup cover 212 are exposed. Of course, in the locked state, the dust cup cover 212 can also be exposed, as long as it ensures that the second locking component 400 cannot be operated at this time.
[0070] In some embodiments, during the dust emptying process, when in the released state, the dust cup assembly is located on the side of the vacuum cleaner 10 closer to the area to be emptied, and when the dust cup 210 is in the released position, the emptying spout 2112 is located at the bottom end of the dust cup body 211. Preferably, when the vacuum cleaner is used alone or as part of a cleaning device, it is generally shaped as follows: Figure 1The dust cup 210 is located on the side closest to the area to be cleaned. Therefore, if the dust cup 210 is full during use, it can be released downwards by simply operating the first operation button 310 without needing to flip the vacuum cleaner or cleaning device. Specifically, when using the vacuum cleaner 10, the dust cup assembly is located on the side closest to the user, and the vacuum cleaner 10 is usually tilted relative to the bed or sofa surface during use. In the released state, the dust cup 210 retains its previous position (approximately at an angle). Figure 1 (As shown in the image) align it with the trash can's emptying area. After releasing the dust cup 210, the dust cup cover 212 is located at the bottom of the dust cup 210. Therefore, after operating the second locking component 400 to open the dust cup cover 212, the pouring spout 2112 is directly exposed. Dust and other debris will automatically pour out under gravity, without manual operation, and the pouring is more thorough, with less residue.
[0071] See Figure 4 In some embodiments, the rotation trajectory of the dust cup 210 between the locked and released states is tangential to the release position, with the direction of the external force applied to the second locking component 400 perpendicular to the first direction. The second locking component 400 is mounted on the dust cup body 211. When the dust cup 210 reaches the release position, if the external force applied to the second locking component 400 is along the first direction, the dust cup body 211 may shake, causing dust to spill from the pouring spout 2112 into the trash can, or causing the dust cup body 211 to open excessively and break at the connection with the dust cup mounting member 220. In this embodiment, since the external force applied to the second locking component 400 is perpendicular to the first direction, when the dust cup cover 212 is opened by operating the second locking component 400, the dust cup body 211 is less likely to shake, dust is less likely to spill out, and the opening action is less likely to cause breakage at the connection between the dust cup body 211 and the dust cup mounting member 220.
[0072] In some embodiments, the dust cup cover 212 is rotatably connected to the dust cup body 211. When the dust cup 210 is in the released position, the second locking component 400 can be separated from the dust cup cover 212 under external force, and the dust cup cover 212 rotates downward relative to the dust cup body 211 to the open position. Specifically, according to the aforementioned conventional operation of using the vacuum cleaner 10, the dust cup assembly is located on the side closer to the user, so that the vacuum cleaner 10 is in a position where... Figure 4In the near-flat position shown, the bottom of the dust cup lid 212 is rotatably connected to the dust cup body 211, and the top is locked by the second locking component 400. Therefore, after applying external force to separate the second locking component 400 from the dust cup lid 212, the dust cup lid 212 will automatically rotate downwards under its own weight and the weight of the dust, thereby opening the pouring spout 2112 and allowing the dust to be automatically poured out under gravity. During this process, only the second locking component 400 needs to be operated, without touching the pouring spout 2112, which can prevent the operator's hands from getting dusty. Preferably, an elastic element such as a torsion spring is provided between the dust cup lid 212 and the dust cup body 211. After applying external force to separate the second locking component 400 from the dust cup lid 212, the rebound force of the torsion spring drives the dust cup lid 212 to rotate downwards. By adding a torsion spring, the lid can be opened quickly.
[0073] See Figure 4 , Figure 6 and Figure 8 In some embodiments, the second locking component 400 includes a first hook portion 411, and the dust cup cover 212 includes a second hook portion 2126. The first hook portion 411 can hook onto the second hook portion 2126 to lock the dust cup cover 212 in the closed position. When the dust cup 210 is in the released position, the first hook portion 411 can be separated from the second hook portion 2126 under external force. Specifically, the first hook portion 411 is a hook, and the second hook portion 2126 is a platform that matches the shape of the hook. Of course, the two can be interchanged, or they can be set to other shapes. Of course, in addition to locking by hooking, locking can also be achieved by snap-fitting. Common snap-fitting structures are all acceptable and will not be described in detail here.
[0074] In some embodiments, the second locking assembly 400 includes a second operating button 410, a third elastic member (not shown in the figure), and a second locking assembly housing 420. The second operating button 410 is provided with a first hook portion 411. The second locking assembly housing 420 is fixedly connected to the dust cup body 211. The third elastic member is connected between the second operating button 410 and the second locking assembly housing 420. The second operating button 410 can move under the action of external force until the first hook portion 411 and the second hook portion 2126 are separated. The third elastic member is used to drive the second operating button 410 to reset after the external force applied to the second operating button 410 is removed. Specifically, the second locking assembly housing 420 can be fixed to the outer side wall of the dust cup body 211 by threaded fasteners, and the second operating button 410 is partially covered by the second locking assembly housing 420. The second locking component housing 420 is also provided with a protruding insert 421, and a corresponding insertion hole 2127 is provided on the dust cup cover 212. When the dust cup cover 212 is closed, the insert 421 is inserted into the insertion hole 2127 for limiting the position. In some other embodiments, the insert 421 and the insertion hole 2127 can also be interchanged.
[0075] In some embodiments, the second operating button 410 is rotatably connected to the second locking component housing 420. The second operating button 410 includes a second operating button pressing portion 412 for receiving external force. The second operating button pressing portion 412 is located at one end of the second operating button 410 away from the first hook portion 411. The second operating button 410 can rotate relative to the second locking component housing 420 under the action of external force until the first hook portion 411 and the second hook portion 2126 are separated. Specifically, the second operating button 410 includes a sleeve portion 413, and the second locking component housing 420 includes a connecting post 422. The sleeve portion 413 is sleeved on the outside of the connecting post 422 to realize the rotatable connection between the second operating button 410 and the second locking component housing 420. The second operating button 410 acts as a lever. When the second operating button pressing part 412 at one end is pressed, the first hook part 411 at the other end will tilt outwards and no longer hook the second hook part 2126. The insert 421 will retract from the insertion hole 2127, and the dust cup cover 212 will rotate downwards under its own weight, thereby opening the pouring spout 2112. When the dust cup cover 212 needs to be closed after pouring, the dust cup cover 212 is pushed in the opposite direction by external force, and the second operating button pressing part 412 is pressed again, causing the first hook part 411 to tilt outwards to avoid the position. After the dust cup cover 212 has rotated into the reverse position, the pressing part 412 is stopped, and the first hook part 411 hooks the second hook part 2126 again, thereby locking the dust cup cover 212 again. In the above embodiment, the second operating button 410 moves by rotation. In other embodiments, the second operating button 410 moves by movement. Figure 4 After reaching the indicated position, pull the second operation button 410 away from the second hook part 2126 to separate the first hook part 411 from the second hook part 2126.
[0076] When the dust cup 210 is full of trash during use, the user can hold the handle with one hand and operate the first operating button 310 with the other hand to release the dust cup 210. Once the dust cup 210 is in the released position and stops shaking, the dust cup lid 212 should be aligned with the trash can again. The hand not holding the handle should then operate the second operating button 410 to open the dust cup lid 212, allowing the trash to be poured into the trash can through the pouring spout 2112. This second alignment of the dust cup 210 with the trash can after it stops shaking ensures more accurate trash entry and prevents spillage.
[0077] Preferably, in the released state, the filter 240 rotates together with the dust cup 210 to the release position. (See also...) Figure 2 , Figure 5 , Figure 6 and Figure 7In some embodiments, the vacuum cleaner also includes a third locking component connected to the housing 100. In the locked state, the dust cup mounting component 220 is locked to the housing 100 by the third locking component; in the released state, the dust cup mounting component 220 is detachably connected to the third locking component. Therefore, in the released state, in addition to opening the dust cup cover 212 to empty the dust, the dust cup mounting component 220 can be removed from the third locking component, thereby removing the entire dust cup assembly from the housing 100 for more thorough cleaning of components such as the filter 240 to ensure good filtration effect. Specifically, the filter 240 is installed in the receiving cavity 2111 of the dust cup body 211. The filter 240 blocks the side of the receiving cavity 2111 away from the pouring port 2112, so that when the dust cup 210 is in the open state, dust can only be poured out from the pouring port 2112, and is not likely to leak from the side away from the pouring port.
[0078] In some embodiments, the third locking component includes a third operating button 510 with a third engaging portion 511, and the dust cup mounting component 220 includes a fourth engaging portion 221. A fourth elastic member (not shown in the figure) connects the third operating button 510 and the housing 100. The third engaging portion 511 can engage with the fourth engaging portion 221 to lock the dust cup assembly to the housing 100. In the released state, the third operating button 510 can move under external force until the third engaging portion 511 and the fourth engaging portion 221 separate. The fourth elastic member is used to drive the third operating button 510 to reset after the external force applied to the third operating button 510 is removed. Specifically, in the embodiment shown in the figures, both the third engaging portion 511 and the fourth engaging portion 221 are hook-shaped. When they hook together, the position of the dust cup assembly can be locked. Of course, in other embodiments, one of them can be a hook or a block, and the other can be a slot. When in the locked state, the dust cup 210 is locked in position by the first locking component 300. Even if the third operation button 510 is operated, the dust cup component cannot be removed. Only when in the released state can the dust cup component be removed by operating the third operation button 510. Therefore, it can prevent the dust cup component from falling off due to accidental triggering of the third operation button 510 during use.
[0079] In some embodiments, the third operation button 510 has a third operation button pressing portion 512 at one end away from the third latching portion 511 for receiving external force. In the released state, the third operation button 510 can rotate under the action of external force until the third latching portion 511 separates from the fourth latching portion 221. Specifically, the movement of the third operation button 510 is rotation, which is equivalent to a lever. When its third operation button pressing portion 512 is pressed, the third latching portion 511 at the other end tilts outward and separates from the fourth latching portion 221. After the third latching portion 511 separates from the fourth latching portion 221, the dust cup mounting member 220 can be pulled away from the third latching portion 511 to completely remove it from the housing 100. In other embodiments, the movement of the third operation button 510 can also be movement, whereby pulling the third operation button 510 outward separates the third latching portion 511 from the fourth latching portion 221. When the dust cup assembly needs to be reinstalled, operate the third operating button 510 again to make the third locking part 511 tilt outward to avoid obstruction. At the same time, put the dust cup mounting part 220 back into its original position and stop operating the third operating button 510 so that the third locking part 511 and the fourth locking part 221 hook together again.
[0080] In some embodiments, the dust cup 210 is provided with a sealing layer, such as a rubber sheet, that can elastically deform under the impact of airflow. When the motor 610 is working, the airflow enters the air duct 120 from the suction port 130 and impacts the sealing layer to enter the dust cup 210, reaching the filter 240 for filtration. When the motor 610 is not working, the sealing layer seals the dust cup 210.
[0081] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0082] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
