Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a dust cup opening mechanism and a vacuum cleaner. Background Technology

[0002] A vacuum cleaner is an electrical appliance used for cleaning. Its main working principle is to use airflow to suck dust and small impurities into the vacuum cleaner. As the airflow passes through the dust cup, a filter traps the dust and small impurities, and the clean airflow is discharged from the outlet. After a period of use, dust and small impurities will accumulate in the dust cup, requiring timely cleaning to avoid affecting the normal operation of the vacuum cleaner. The dust cup typically consists of an interlocking dust cup body and a dust cup lid. To clean the dust cup, the lid must first be opened. The dust cup body and lid are generally connected by a locking mechanism and a release switch, allowing the lid to open and close.

[0003] In related technologies, the release switch is usually located near the dust cup lid. When the dust cup needs to be opened, the user needs to hold the handle with one hand and operate the release switch with the other hand. This is inconvenient to operate, and the dust in the dust cup may contaminate the user's hands after the dust cup lid is opened, reducing the user's experience. Utility Model Content

[0004] The purpose of this utility model is to provide a dust cup opening mechanism and a vacuum cleaner, which is easy to operate and improves the user experience.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] On one hand, a dust cup opening mechanism is provided, comprising: a dust cup body, a dust cup cover, a locking assembly, a transmission assembly, and a release switch. The dust cup cover is rotatably connected to the dust cup body, and the dust cup body has an opening for dust discharge. The dust cup cover is capable of closing or opening the opening. The transmission assembly is tractively connected between the locking assembly and the release switch. The locking assembly has a first state of locking the relative position of the dust cup cover and the dust cup body, and a second state of unlocking the relative position of the dust cup cover and the dust cup body. The release switch is movably connected to the handle of a vacuum cleaner so that the release switch has a locked position and a released position. When the release switch is in the locked position, the locking assembly is in the first state, and when the release switch is in the released position, the locking assembly is in the second state.

[0007] Preferably, the transmission assembly includes a rotating component, a drive shaft, a steel cable, a roller, and a first rotating shaft. The rotating component is used to be embedded in the clearance groove of the vacuum cleaner handle. The rotating component is rotatably connected to the drive shaft. Along the length direction of the rotating component, one end of the rotating component is fixedly connected to a release switch, and the other end of the rotating component is fixedly connected to the steel cable. The first rotating shaft is used to be fixedly connected to the body of the vacuum cleaner. The roller is rotatably connected to the first rotating shaft. The steel cable is wound around the roller, and the end of the steel cable away from the rotating component is fixedly connected to a locking assembly.

[0008] Preferably, the transmission assembly further includes a first reset spring, one end of which is fixedly connected to the end of the rotating member connected to the release switch, and the first reset spring and the release switch are located on opposite sides of the rotating member, and the other end of the first reset spring is used to abut against the inner wall of the clearance groove.

[0009] Preferably, the transmission assembly includes multiple rollers and multiple first rotating shafts, with the multiple first rotating shafts spaced apart between the release switch and the locking assembly, and the multiple rollers rotatably connected to the multiple first rotating shafts in a one-to-one correspondence, with steel cables sequentially wound around the multiple rollers.

[0010] Preferably, the locking assembly includes an elastic element, a slot, and a movable element. The slot is disposed on the dust cup cover, the elastic element is fixedly connected to the dust cup body, the elastic element has a sliding groove and a protrusion, the elastic element can undergo elastic deformation so that the protrusion can engage with or disengage from the slot, and the movable element is slidably connected in the sliding groove. When the locking assembly is in the first state, the movable element is separated from the elastic element, and the protrusion engages with the slot. When the locking assembly is in the second state, the movable element abuts against the elastic element, and the protrusion disengages from the slot. The end of the steel cable away from the rotating element is fixedly connected to the movable element.

[0011] Preferably, the elastic element includes two fixing parts and two latching protrusions, and a connecting part connected to the two fixing parts. The two fixing parts are fixedly connected to the dust cup body by fasteners, and the connecting part forms a sliding groove. The two latching protrusions are respectively disposed at the connection between the two fixing parts and the connecting part.

[0012] Preferably, the outer peripheral wall of the dust cup body is provided with a mounting groove, and the elastic element is disposed in the mounting groove.

[0013] Preferably, the bottom wall of the mounting groove is provided with a limiting part, and when the dust cup cover closes the opening, the groove wall of the slot abuts against the limiting part.

[0014] Preferably, the dust cup opening mechanism further includes a second rotating shaft and a torsion spring. The second rotating shaft is rotatably connected to the dust cup body, the torsion spring is sleeved outside the second rotating shaft, the dust cup cover passes through the second rotating shaft, and one end of the torsion spring abuts against the dust cup body, while the other end of the torsion spring abuts against the dust cup cover.

[0015] On the other hand, a vacuum cleaner is provided, which includes a body, a handle and a dust cup opening mechanism of any of the above-mentioned technical solutions, wherein the dust cup is detachably connected to the body, the handle is fixedly connected to the end of the body away from the dust cup, and the handle is provided with a clearance groove.

[0016] The beneficial effects of this utility model are as follows:

[0017] A dust cup opening mechanism and a vacuum cleaner are provided. The dust cup opening mechanism movably connects a release switch to the handle of the vacuum cleaner and connects the release switch and a locking component through a transmission component. This allows the user to operate the release switch on the handle directly with their fingers (such as the thumb or index finger) while holding the handle, eliminating the need to use one hand to hold the handle and the other hand to operate the release switch near the dust cup cover. By placing the release switch on the vacuum cleaner handle away from the dust cup cover, the operation process of cleaning the dust cup is greatly simplified, while avoiding the risk of contamination of the operator's hands when dust is released from the dust cup, thus improving the user experience.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0033] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0035] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0036] On the one hand, please refer to Figures 1 to 8 This embodiment provides a dust cup opening mechanism, including: a dust cup body 1, a dust cup cover 2, a locking assembly 3, a transmission assembly 4, and a release switch 5. The dust cup cover 2 is rotatably connected to the dust cup body 1. The dust cup body 1 has an opening 13 for dust discharge. The dust cup cover 2 can close or open the opening 13. The transmission assembly 4 is tractively connected between the locking assembly 3 and the release switch 5. The locking assembly 3 has a first state of locking the relative position of the dust cup cover 2 and the dust cup body 1, and a second state of unlocking the relative position of the dust cup cover 2 and the dust cup body 1. The release switch 5 is movably connected to the handle 8 of the vacuum cleaner so that the release switch 5 has a locked position and a released position. When the release switch 5 is in the locked position, the locking assembly 3 is in the first state. When the release switch 5 is in the released position, the locking assembly 3 is in the second state.

[0037] With this configuration, the dust cup opening mechanism movably connects the release switch 5 to the vacuum cleaner handle 8 and connects the release switch 5 and the locking component 3 through the transmission component 4. This allows the user to operate the release switch 5 on the handle 8 directly with their fingers (such as the thumb or index finger) while holding the handle 8, eliminating the need to use one hand to hold the handle 8 and the other hand to operate the release switch 5 near the dust cup cover 2. By placing the release switch 5 on the vacuum cleaner handle 8 away from the dust cup cover 2, the operation process of cleaning the dust cup is greatly simplified, while avoiding the risk of contamination of the operator's hands when dust is released from the dust cup body 1, thus improving the user experience.

[0038] Further, please refer to Figures 2 to 4The transmission assembly 4 includes a rotating member 41, a drive shaft 42, a steel cable 43, a roller 44, and a first rotating shaft 45. The rotating member 41 is fitted into the clearance groove 81 of the vacuum cleaner handle 8. The rotating member 41 is rotatably connected to the drive shaft 42. Along the length of the rotating member 41, one end of the rotating member 41 is fixedly connected to the release switch 5, and the other end of the rotating member 41 is fixedly connected to the steel cable 43. The first rotating shaft 45 is fixedly connected to the body of the vacuum cleaner. The roller 44 is rotatably connected to the first rotating shaft 45. The steel cable 43 is wound around the roller 44, and the end of the steel cable 43 away from the rotating member 41 is fixedly connected to the locking assembly 3. With this configuration, the rotating member 41 acts as a lever. When the user pushes the release switch 5, the other end of the rotating member 41 pulls the steel cable 43, thereby triggering the locking assembly 3 to switch between the first and second states. Meanwhile, by setting the first rotating shaft 45, the movement of the steel cable 43 is reversed. While accurately triggering the locking component 3, it is convenient for the transmission component 4 to be arranged on the body of the vacuum cleaner. The roller 44 is rotatably connected to the first rotating shaft 45, which reduces the friction between the steel cable 43 and the first rotating shaft 45, ensuring that the steel cable 43 can move smoothly and avoiding wear of the steel cable 43. This ensures reliable transmission and improves the service life of the device.

[0039] Optionally, the transmission assembly 4 further includes a first return spring 46. One end of the first return spring 46 is fixedly connected to the end of the rotating member 41 connected to the release switch 5, and the first return spring 46 and the release switch 5 are located on opposite sides of the rotating member 41. The other end of the first return spring 46 is used to abut against the inner wall of the clearance groove 81. With this configuration, when the dust and impurities inside the dust cup 1 are emptied, the operator only needs to release the release switch 5, which increases the restoring force provided by the first return spring 46, so that the release switch 5 and the rotating member 41 automatically return to the locked position, and the locking assembly 3 returns to the first state. No manual reset is required, making the operation simple. At the same time, the locking assembly 3 is always in the locked state when there is no continuous external force, preventing the dust cup from being accidentally opened.

[0040] Optionally, the transmission assembly 4 includes multiple rollers 44 and multiple first rotating shafts 45. The multiple first rotating shafts 45 are spaced apart between the release switch 5 and the locking assembly 3. The multiple rollers 44 are rotatably connected to the multiple first rotating shafts 45 in a one-to-one correspondence. The steel cable 43 is wound around the multiple rollers 44 in sequence. This configuration allows the steel cable 43 to be divided into several straight or gently zigzag segments via multiple sets of rollers 44. This avoids obstacles such as motors, air ducts, and batteries, while ensuring the steel cable 43 always runs close to the wall, resulting in a more compact overall structure. Each time the cable passes a roller 44, the sliding friction of that segment is transformed into rolling friction. The multiple rollers 44 "cut" the long friction distance into several smaller segments, each with a small wrap angle and low tension, significantly reducing overall friction, extending the lifespan of the steel cable 43, and requiring less operating force. Multi-point support reduces localized stress concentration in the steel cable 43. The shared load among the rollers 44 reduces single-point wear, resulting in more stable transmission efficiency and preventing the steel cable 43 from slipping, jamming, or sluggishly. This makes the dust cup opening mechanism compact, reliable, and durable. In this embodiment, the transmission component 4 has three rollers 44 and three first rotating shafts 45. In other embodiments, the number and position of the rollers 44 and first rotating shafts 45 can be adjusted according to the size of the vacuum cleaner and the actual layout space.

[0041] Further, please refer to Figures 4 to 6 The locking assembly 3 includes an elastic element 31, a slot 32, and a movable element 33. The slot 32 is disposed on the dust cup cover 2. The elastic element 31 is fixedly connected to the dust cup body 1. The elastic element 31 has a sliding groove 311 and a protrusion 312. The elastic element 31 can undergo elastic deformation so that the protrusion 312 can engage with or disengage from the slot 32. The movable element 33 is slidably connected in the sliding groove 311. When the locking assembly 3 is in the first state, the movable element 33 is separated from the elastic element 31, and the protrusion 312 engages with the slot 32. When the locking assembly 3 is in the second state, the movable element 33 abuts against the elastic element 31, and the protrusion 312 disengages from the slot 32. The end of the steel cable 43 away from the rotating element 41 is fixedly connected to the movable element 33.

[0042] Specifically, a second reset spring is provided between the movable part 33 and the vacuum cleaner body. When the steel cable 43 does not provide tension to the movable part 33, the movable part 33 is located at the far end of the sliding groove 311 and separated from the elastic member 31. The elastic member 31 uses its own elastic force to keep the latch 312 locked in the slot 32, and the dust cup cover 2 is locked, and the locking component 3 is in the first state. When the operator pushes the release switch 5, the steel cable 43 is pulled, pulling the movable part 33 to slide along the sliding groove 311 toward the elastic member 31. The movable part 33 pushes the elastic member 31 to make it elastically deform, and the latch 312 moves inward and disengages from the slot 32. The dust cup cover 2 is unrestrained and can be opened freely. When the finger releases the release switch 5, the tension of the steel cable 43 disappears. Under the action of the second reset spring, the movable part 33 resets, and the elastic member 31 rebounds after losing tension, so that the latch 312 is locked into the slot 32 again, returning to the first state.

[0043] Specifically, the elastic element 31 includes two fixing portions 313 and two latching protrusions 312, and a connecting portion 314 connected to the two fixing portions 313. The two fixing portions 313 are fixedly connected to the dust cup body 1 by fasteners. The connecting portion 314 forms a sliding groove 311, and the two latching protrusions 312 are respectively disposed at the connection points between the two fixing portions 313 and the connecting portion 314. The connecting portion 314 is U-shaped, and the fastener can be a screw, bolt, etc. The two protrusions 312 simultaneously engage with the two slots 32 on the dust cup cover 2, resulting in symmetrical force application and a more secure locking of the dust cup cover 2, preventing it from tilting up on one side. The connecting part 314 acts as an elastic beam. When the moving part 33 is pulled into the sliding groove 311 by the steel cable 43, the columnar structure on the moving part 33 contacts the middle section of the connecting part 314. As the sliding continues, the connecting part 314 elastically deforms inward, and the two protrusions 312 simultaneously disengage from their respective slots 32. When the steel cable 43 is no longer under tension, the connecting part 314 rebounds, causing the two protrusions 312 to reset synchronously.

[0044] Alternatively, please refer to Figure 7 The outer peripheral wall of the dust cup body 1 is provided with a mounting groove 11, and the elastic element 31 is disposed in the mounting groove 11. The mounting groove 11 provides mounting space for the elastic element 31, making it easy to install the elastic element 31 on the dust cup body 1. By setting the elastic element 31 in the mounting groove 11 of the dust cup body 1, the component is installed in a hidden manner, making the dust cup opening mechanism compact and easy to arrange on the vacuum cleaner.

[0045] Alternatively, please refer to Figure 5 and Figure 7 The bottom wall of the mounting groove 11 is provided with a limiting part 12. When the dust cup cover 2 closes the opening 13, the groove wall of the slot 32 abuts against the limiting part 12. By abutting against the groove wall of the slot 32, the limiting part 12 can prevent the groove wall of the slot 32 from shaking, and avoid the disengagement of the locking protrusion 312 from the slot 32 due to equipment vibration or accidental contact, thus ensuring that the dust cup cover 2 remains tightly closed in the latched state.

[0046] Alternatively, please refer to Figure 5 The dust cup opening mechanism also includes a second rotating shaft 6 and a torsion spring 7. The second rotating shaft 6 is rotatably connected to the dust cup body 1, and the torsion spring 7 is sleeved on the outside of the second rotating shaft 6. The dust cup cover 2 passes through the second rotating shaft 6, and one end of the torsion spring 7 abuts against the dust cup body 1, while the other end of the torsion spring 7 abuts against the dust cup cover 2. When the release switch 5 is in the release position, the locking component is in the unlocked second state, and the dust cup cover 2 rotates around the rotating shaft under the elastic action of the torsion spring 7, which can quickly open the dust cup cover 2.

[0047] On the other hand, please refer to Figure 8 This embodiment provides a vacuum cleaner, which includes a body, a handle 8, and a dust cup opening mechanism according to any of the above-described technical solutions. The dust cup body 1 is detachably connected to the body, and the handle 8 is fixedly connected to the end of the body away from the dust cup body 1. The handle 8 is provided with a relief groove 81. While holding the vacuum cleaner handle, the operator can drag the release switch 5 with their finger to open the dust cup cover 2, allowing dust and impurities to be poured out from the dust cup body 1, thus cleaning the vacuum cleaner. By placing the release switch 5 on the vacuum cleaner handle 8 away from the dust cup cover 2, the operation process of cleaning the dust cup is greatly simplified. At the same time, it avoids the risk of operator's hands being contaminated when dust is released from the dust cup body 1, improving the user experience.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
