Description

Technical Field

[0001] This application relates to the field of vacuum cleaner technology, and in particular to a vacuum cleaner snap-fit ​​component and a vacuum cleaner system. Background Technology

[0002] Upright vacuum cleaners are widely used due to their portability and flexibility. To empty the dust cup, users typically need to manually remove and empty it, a process that can easily cause dust to fly around and create secondary pollution. To solve this problem, vacuum cleaner systems with automatic dust collection base stations have emerged. Users simply place the upright vacuum cleaner back into the base station, which automatically sucks the dust from the dust cup into a larger dust bag.

[0003] In upright vacuum cleaners, the reliability of the connection between the dust cup and the base station is crucial; a weak connection can cause the dust cup to detach during dust collection. Existing snap-fit ​​structures between the dust cup and the base station often use a single snap-fit ​​mechanism, which suffers from insufficient strength, leading to the dust cup falling off the base station and affecting subsequent dust removal and the user experience.

Detailed Implementation

[0028] The technical solution of the present invention will be further described in detail below with reference to embodiments and accompanying drawings. The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms.

[0029] The vacuum cleaner snap-fit ​​assembly provided in this application includes a base station 1 and a dust cup 2.

[0030] The base station 1 is provided with a first space 10, the first space 10 is provided with a card interface 11, and a first card connector 10c and a second card connector 10d are provided on the inner wall of the first space 10, which are respectively located on both sides of the card interface 11.

[0031] The dust cup 2 is detachably snapped into the first space 10 from the card interface 11, such as Figure 4 As shown, the vertical distance between the two adjacent tip positions in the first snap-fit ​​10c and the second snap-fit ​​10d is the minimum vertical distance.

[0032] When the dust cup 2 is located within the first space 10, the minimum vertical distance is less than the outer diameter of the dust cup 2 to confine the dust cup 2 within the first space 10; the minimum vertical distance can be adjusted to be greater than the outer diameter of the dust cup 2 after being subjected to force so that the dust cup 2 can be inserted into or detached from the first space 10.

[0033] The vacuum cleaner snap-fit ​​assembly provided in this application embodiment, by setting the minimum vertical distance between the first snap-fit ​​member 10c and the second snap-fit ​​member 10d to be less than the outer diameter of the dust cup 2 when the dust cup 2 is located in the first space 10, confines the dust cup 2 in the first space 10, ensuring the firmness and stability of the dust cup 2 snap-fit ​​in the base station 1, effectively preventing the dust cup 2 from falling off the base station 1, and improving the user experience; the minimum vertical distance can be adjusted to be greater than the outer diameter of the dust cup 2 after being subjected to force so that the dust cup 2 can be snapped into the first space 10 or detached from the first space 10.

[0034] In one embodiment where the minimum vertical distance between the first latching member 10c and the second latching member 10d is adjustable, both the first latching member 10c and the second latching member 10d are rotatably connected within the first space 10 and are rotatable in the vertical direction. The pivots of the first latching member 10c and the second latching member 10d are both located in grooves formed in the inner wall of the first space 10. When the dust cup 2 is inserted, the first latching member 10c and the second latching member 10d rotate to increase the minimum vertical distance position within the first space 10, thus facilitating the insertion of the dust cup 2. After the dust cup 2 is inserted, the first latching member 10c and the second latching member 10d rotate back to a position where the minimum vertical distance between them is less than that between the dust cup 2, and are then limited by an elastic member fixed at a certain point in the first space 10. Specifically, an elastic element is installed in a groove on the inner wall of the first space 10. The elastic element is located between the rotating shaft and the locking interface 11. When the first locking member 10c and the second locking member 10d rotate to the side near the locking interface 11 and elastically abut against the elastic element, they are limited by the elastic element. The first locking member 10c and the second locking member 10d cannot continue to rotate, thus limiting the insertion of the dust cup 2. The elastic abutment of the elastic element allows the first locking member 10c and the second locking member 10d to be stably clamped on both sides of the dust cup 2, increasing the reliability of the dust cup 2 within the first space 10. When the dust cup 2 needs to be removed from the first space 10, the first locking member 10c and the second locking member 10d are squeezed. They overcome the elastic force limitation of the elastic element and continue to rotate, increasing the minimum vertical distance and allowing the dust cup 2 to be removed from the first space 10. The elastic element can be a structure with elasticity such as rubber, spring, or silicone.

[0035] In another embodiment where the minimum vertical distance between the first latching member 10c and the second latching member 10d is adjustable, both the first latching member 10c and the second latching member 10d can be made of engineering plastics or the like. They are respectively installed in two grooves opened in the inner wall of the first space 10 via elastic structures with good restoring force, such as springs, and can retract after being compressed and extend to their original position after the pressure disappears or decreases. Alternatively, the first latching member 10c and the second latching member 10d can also be structures made of rubber, silicone, or other materials that possess inherent elasticity. This embodiment allows the first snap-fit ​​component 10c and the second snap-fit ​​component 10d to be compressed and retracted by the dust cup 2 when the dust cup 2 is snapped into the first space 10, increasing the minimum vertical distance and generating an elastic restoring force. After the dust cup 2 is snapped onto the base station 1, the first snap-fit ​​component 10c and the second snap-fit ​​component 10d are fitted and clamped to both sides of the outer wall of the dust cup 2 under the action of the elastic restoring force, making the minimum vertical distance less than the outer diameter of the dust cup 2, generating a continuous radial clamping force on the dust cup 2, ensuring the firmness and stability of the dust cup 2 in the base station 1, effectively preventing the dust cup 2 from loosening or falling off the base station 1, and improving the user experience.

[0036] In an optional embodiment, the first latching member 10c includes a first latching surface 100c, and the second latching member 10d includes a second latching surface 100d; when the dust cup 2 is latched into the first space 10, both the first latching surface 100c and the second latching surface 100d are in contact with the outer wall of the dust cup 2, and the vertical distance between the first latching surface 100c and the second latching surface 100d gradually decreases or remains constant along the direction close to the latching interface 11. Please refer to... Figure 4 The first contact surface 100c and the second contact surface 100d form a tapered structure along the direction close to the contact interface 11 to fit the arc-shaped outer wall of the dust cup 2, or remain unchanged to adapt to the outer wall of the dust cup 2 with no change in outer diameter. This can provide a more stable radial clamping force to the dust cup 2 and increase the stability of the dust cup 2 in the first space 10.

[0037] In an optional embodiment, the first card connector 10c further includes a third card connector surface 101c, and the second card connector 10d further includes a fourth card connector surface 101d; the third card connector surface 101c is located between the first card connector surface 100c and the card interface 11, and the fourth card connector surface 101d is located between the second card connector surface 100d and the card interface 11, with the vertical distance between the third card connector surface 101c and the fourth card connector surface 101d gradually increasing along the direction closer to the card interface 11. Please refer to... Figures 4 to 6 The third contact surface 101c and the fourth contact surface 101d form an flared structure along the insertion direction of the dust cup 2, which facilitates guiding the dust cup 2 into the contact interface 11 and increases the smoothness of the dust cup 2's engagement.

[0038] In an optional embodiment, a resilient third latching member 11a is provided on the bottom wall of the card interface 11; a limiting opening 24 is provided on the bottom wall of the dust cup 2 to engage with the third latching member 11a. Figures 9 to 10 As shown, the limiting port 24 has a certain height along the axial direction of the dust cup 2. The third locking member 11a cooperates with the limiting port 24 to complete the positioning and locking of the dust cup 2 in the axial direction, further increasing the locking stability of the dust cup 2 and the base station 1. Among them, a sealing member 10b can be provided on the bottom wall of the locking interface 11 in the outer peripheral area of ​​the ash outlet 21. The material of the sealing member 10b can be made of rubber or the like. The third locking member 11a is located on the outer periphery of the sealing member 10b. A planar or arc-shaped sealing area 23 extending circumferentially can be provided on the bottom wall of the dust cup 2. When the dust cup 2 is locked to the base station 1, the sealing area 23 and the sealing member 10b are in contact and sealed.

[0039] In an optional embodiment, the third latching member 11a is a wedge-shaped member, the surface of the third latching member 11a facing away from the insertion direction of the dust cup 2 is a limiting vertical surface 110a, and the surface of the third latching member 11a facing the insertion direction of the dust cup 2 is a guide slope 111a. Figure 5 The direction indicated by the middle arrow is the insertion direction of the dust cup 2. When the dust cup 2 is inserted into the first space 10, it first contacts the guide slope 111a. The guide slope 111a allows the dust cup 2 to easily press the third locking piece 11a into the limiting port 24 when it is pushed in laterally, thus achieving precise positioning of the dust cup 2. After the dust cup 2 is in place, the limiting vertical surface 110a engages with the side wall of the limiting port 24 along the axial direction, effectively preventing the dust cup 2 from accidentally detaching upwards, and forming a two-way locking with the first locking piece 10c and the second locking piece 10d at the top.

[0040] The bottom wall of the card interface 11 may be provided with a snap-fit ​​groove. The third snap-fit ​​member 11a is installed in the snap-fit ​​groove by an elastic element such as a spring and can be extended and retracted. At this time, a guide groove may be opened on the third snap-fit ​​member 11a, and a limit strip is provided on the snap-fit ​​groove to guide the sliding of the third snap-fit ​​member 11a; or the third snap-fit ​​member 11a is a rubber or silicone part with a certain elasticity.

[0041] In an optional embodiment, a first groove and a second groove are respectively provided on the inner wall of the first space 10. The first snap-fit ​​member 10c is movably installed in the first groove through a first elastic member, and the second snap-fit ​​member 10d is movably installed in the second groove through a second elastic member. The first elastic member and the second elastic member can be springs or rubber blocks. The first snap-fit ​​member 10c is detachably connected to the first elastic member, and the second snap-fit ​​member 10d is detachably connected to the second elastic member. The clamping force can be precisely adjusted by replacing springs of different stiffness or rubber blocks of different hardness to adapt to dust cups 2 of different models and sizes, resulting in high adaptability. Moreover, if the first snap-fit ​​member 10c or the second snap-fit ​​member 10d is worn, the first snap-fit ​​member 10c or the second snap-fit ​​member 10d can be replaced individually, reducing maintenance costs.

[0042] Furthermore, the first groove and the second groove are respectively provided with protrusions that guide the first snap-fit ​​member 10c and the second snap-fit ​​member 10d to slide. The first snap-fit ​​member 10c and the second snap-fit ​​member 10d are respectively provided with sliding grooves that slide and engage with the protrusions to achieve sliding guidance.

[0043] In an optional embodiment, a dust discharge trigger 10a is further provided on the inner wall of the first space 10; the dust cup 2 includes a dust discharge control 20, a dust discharge port 21 located on the bottom wall of the dust cup 2, and a cover plate 22. The cover plate 22 is rotatably configured to open or close the dust discharge port 21. The dust discharge control 20 abuts against the dust discharge trigger 10a to receive pressure and control the cover plate 22 to open or be in an openable state. In this embodiment, after the dust cup 2 is installed in the first space 10, the dust discharge control 20 abuts against the dust discharge trigger 10a to receive pressure and control the cover plate 22 to be in an unlocked state. At this time, the cover plate 22 opens automatically or is in an openable state, opening under the suction force of the base station 1, without requiring the user to manually open the dust cup 2, which is convenient and hygienic.

[0044] In an optional embodiment, the dust cup 2 is provided with a rotating shaft, and the ash discharge control component 20 includes a bent pressing plate 20a and a limiting plate 20b. The ash discharge control component 20 is connected to the rotating shaft, and the limiting plate 20b is detachably engaged with the cover plate 22 via a connecting assembly. When the pressing plate 20a abuts against the ash discharge trigger 10a, it drives the limiting plate 20b to rotate downwards and disengage from the cover plate 22. In this embodiment, the rotating shaft can be located on the side wall of the dust cup 2 near the bottom, or on the upper part of the bottom wall of the dust cup 2. Utilizing the lever principle, the ash discharge trigger 10a of the base station 1 applies a small stroke and force to the pressing plate 20a, which can be amplified by the rotating shaft into a larger downward rotation of the limiting plate 20b, reliably releasing the restriction on the cover plate 22. The end of the limiting plate 20b may be provided with a hook, and the cover plate 22 is provided with a corresponding slot to realize the detachable connection between the limiting plate 20b and the cover plate 22; in addition, in order to increase the reliability of the engagement between the slot and the hook, an elastic element is installed on the hook to allow the hook to extend and retract axially, so as to facilitate the smooth engagement between the hook and the slot.

[0045] Furthermore, a torsion spring is provided on the rotating shaft. When the pressing plate 20a is pressed and the rotating shaft rotates, the torsion spring is in a tensioned state. When the dust cup 2 is removed from the base station 1 and the pressure of the pressing plate 20a disappears, the torsion spring can automatically reset the rotating shaft, thereby resetting the limiting plate 20b and making the limiting plate 20b lock the cover plate 22 again.

[0046] In an optional embodiment, the base station 1 is provided with a suction unit located below the first space 10. The suction unit includes a suction port that is connected to the first space 10. A control contact 12 is provided on the inner wall of the first space 10. The control contact 12 is controlled and connected to the suction unit. When the dust cup 2 is inserted into the first space 10, it squeezes the control contact 12, and the suction unit is in an openable state. When the dust cup 2 is removed from the first space 10, the control contact 12 resets. Figure 5 As shown, the control contact 12 is located on the side of the first space 10. After the dust cup 2 is inserted into the first space 10, the control contact 12 is pressed and moves backward, and the suction unit is in an openable state. At this time, the suction unit can be opened by controlling the control switch located on the base station 1 or the vacuum cleaner 3. The suction unit starts to generate downward suction force on the suction port, sucking the open cover 22 to a vertical or near-vertical position. The dust in the dust cup 2 is sucked into the dust collection bag of the base station 1. After the dust cup 2 is removed from the first space 10, the squeezing force on the control contact 12 is released, the control contact 12 is reset, and the suction unit is in an open state.

[0047] A return spring can be provided on the control contact 12. When the control contact 12 is pressed, it moves backward to close the series circuit of the suction unit, connecting the control contact 12 and the suction unit. The suction unit is in an openable state, and the return spring is compressed at this time. When the control switch (such as a button or touch screen) on the base station 1 or the vacuum cleaner host 3 is operated, the remaining series circuit of the suction unit can be closed, and the suction unit starts to work; or when the control switch (such as a button or touch screen) is operated, one of the remaining parallel circuits of the suction unit can be closed, so that the suction unit works in the mode set by the parallel circuit. After the dust cup 2 is separated from the first space 10, the control contact 12 moves forward to reset under the action of the return spring, disconnecting part of the circuit of the suction unit, and the suction unit stops working.

[0048] The suction unit may include a fan, with fan blades located at the end of the motor, generating negative pressure when rotating. Since the suction unit is a fairly standard structure in vacuum cleaners, it will not be described in detail in this embodiment.

[0049] In an optional embodiment, a first pressure sensor is provided on the first snap-fit ​​surface 100c, and a second pressure sensor is provided on the second snap-fit ​​surface 100d; an indicator light is provided on the base station 1, and both the first pressure sensor and the second pressure sensor are communicatively connected to a controller that controls the indicator light to turn on or off; when the first pressure value detected by the first pressure sensor and the second pressure value detected by the second pressure sensor are both greater than a preset value, it indicates that the holding force between the first snap-fit ​​component 10c and the dust cup 2 and the second snap-fit ​​component 10d and the dust cup 2 are both in a stable snap-fit ​​state, the dust cup 2 is firmly clamped in the first space 10, and the controller controls the indicator light to light up, so as to remind the user that the dust cup 2 has been stably installed in the first space 10 and the suction unit can be turned on.

[0050] The preset value can be a value between 0.3 MPa and 0.8 MPa. When both the first pressure value and the second pressure value are greater than this value, it indicates that both the first contact surface 100c and the second contact surface 100d are in a state of effectively holding the dust cup 2.

[0051] This application also provides a vacuum cleaner system, including a vacuum cleaner main unit 3 and a vacuum cleaner snap-fit ​​assembly as described in any of the above embodiments, wherein the dust cup 2 is installed on the vacuum cleaner main unit 3. The dust cup 2 is detachably snap-fitted onto the vacuum cleaner main unit 3 and can be used for cleaning operations along with the main unit. After cleaning is completed, the main unit and the dust cup 2 are placed back into the base station 1 for automatic dust removal.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
