Description

Technical Field

[0001] This utility model relates to the field of vacuum equipment technology, and more specifically to a dust cup opening structure, a dust cup, a vacuum cleaner, and a base station. Background Technology

[0002] With the advancement of technology, the integration of dust collection stations into products has become a trend in the cleaning appliance industry. The combination of vacuum cleaners and dust collection stations not only enables automatic dust collection and frees up hands, but also, more importantly, helps mitigate suction power loss by cleaning the dust cup and other filter components with each dust collection.

[0003] Currently, vacuum cleaners with dust collection base stations on the market generally use a top-and-bottom opening dust cup design. For example, Chinese patent number CN220327296U discloses a dust collection chamber opening structure, a vacuum cleaner, and a docking base station. This prior art achieves automatic cleaning by having the dust cup's suction hole flip open outwards under external negative pressure, thus connecting to the base station. The flip-top opening is a downward-opening structure. However, both top-and-bottom opening structures have drawbacks: First, the top-and-bottom opening structure requires determining the direction of the base station's waste transport pipe to decide whether the dust cup cover opens top-and-bottom, increasing the variety of structural options, reducing structural versatility, and leading to high product development costs and long development cycles. Second, the opening direction of the dust cup is often opposite to the suction direction of the base station, causing the opening angle of the dust cup cover to be affected by airflow, making it difficult to fully open for dust collection and increasing the probability of waste residue. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings of the prior art, this utility model provides a dust cup opening structure with strong structural versatility, a dust cup, a vacuum cleaner and a base station. The structure is simple and reliable, and it is easy to collect dust, which can reduce the probability of garbage residue.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dust cup opening structure, which is provided on the dust cup of a vacuum cleaner. The dust cup is provided with a dust cup opening, and the base station connected to the vacuum cleaner is provided with a base station suction port. The positions of the dust cup opening and the base station suction port correspond. The dust cup opening structure includes a dust cup cover, which is provided on the left or right side of the dust cup opening.

[0006] This utility model provides a dust cup opening structure. The structure is simple and reliable, and can be used with a base station. It can automatically complete the opening and dust collection of the dust cup during the process of placing the vacuum cleaner into the base station, collecting and cleaning dust, and taking it out of the base station. The structure has strong versatility, can avoid the residue of garbage in the dust cup, is simple and effective, highly reliable, low cost, and can effectively improve the user experience.

[0007] In one technical solution, the dust cup cover is hinged to the dust cup opening via a pivot, and the pivot is provided with an elastic reset component, which is used to drive the dust cup cover to elastically reset and close after it is opened.

[0008] Furthermore, the elastic reset element is a torsion spring, which is wound around the rotating shaft, with one end of the torsion spring connected to the end of the dust cup cover near the rotating shaft. This technology uses a torsion spring as the elastic reset element, which facilitates installation and maintenance. Moreover, the torsion spring structure is stable, readily available, and inexpensive, helping to reduce product costs.

[0009] In one technical solution, the dust cup cover is made of a soft elastic material, so that after the dust cup cover is opened, it automatically resets and closes under the elastic action of the soft elastic material itself, which further simplifies the reset structure of the dust cup cover. The dust cup cover can complete the opening and closing action entirely by its own elasticity.

[0010] In one technical solution, the dust cup opening structure also includes a dust cup cover release mechanism; the dust cup cover release mechanism is used to lock the dust cup cover when the vacuum cleaner is not connected to the base station, so that the dust cup cover is in a closed state; and to unlock the dust cup cover after the vacuum cleaner is connected to the base station.

[0011] In one technical solution, the dust cup cover release mechanism includes a key cover and a movable key. The movable key includes an upper baffle, a locking part, and a lower baffle connected sequentially from top to bottom. The upper end of the upper baffle extends into the gap between the key cover and the side wall of the dust cup, and moves up and down within the gap under the action of the locking part. A spring is provided between the upper baffle and the side wall of the dust cup. One end of the spring is fixedly connected to the upper end of the key cover, and the other end is connected to the upper end of the locking part, facilitating the reset of the dust cup cover release mechanism. When the dust cup cover release mechanism is in the locked state, the lower baffle is located in front of the dust cup cover to prevent the dust cup cover from opening outwards. The base station has a protrusion that cooperates with the locking part for unlocking the dust cup cover release mechanism. The dust cup cover release mechanism in this technology better protects the movable key by providing a key cover, and unlocks the dust cup cover release mechanism by cooperating with the protrusion of the base station through the locking part. The structure is simple, stable, and has good applicability.

[0012] In one technical solution, the dust cup is provided with an installation guide groove, and the base station is provided with an installation guide protrusion; the installation guide groove and the installation guide protrusion are slidably engaged, and the dust cup is connected to the base station through the cooperation of the installation guide groove and the installation guide protrusion.

[0014] A dust cup, including the dust cup opening structure as described in any of the above technical solutions.

[0015] The dust cup in this utility model adopts the above-mentioned dust cup opening structure. Since the opening direction of the dust cup cover is axially opened from the side, on the one hand, there is no need to consider the direction of the garbage conveying pipeline of the base station, the structure has better versatility, which can reduce product development costs and shorten the development cycle. On the other hand, the dust cup cover opens from the side, and its opening angle is not affected by airflow. It can be fully opened when collecting dust, reducing the probability of garbage residue in the dust cup.

[0016] This utility model also provides a vacuum cleaner that uses the above-mentioned dust cup opening structure. This vacuum cleaner has the advantages of strong structural versatility and can avoid the residue of garbage in the dust cup.

[0017] A vacuum cleaner includes a dust cup as described in any of the above-described technical solutions.

[0018] The vacuum cleaner in this application uses the aforementioned dust cup.

[0034] Reference Figure 1-8This invention describes a dust cup opening structure 1, a dust cup 2, a vacuum cleaner 3, and a base station 4 according to an embodiment of the present invention.

[0035] In one embodiment, such as Figure 1-6 As shown, a dust cup opening structure 1 is provided on the dust cup 2 of a vacuum cleaner 3. The dust cup 2 is provided with a dust cup opening 21, and the base station 4 connected to the vacuum cleaner 3 is provided with a base station suction port 41. The positions of the dust cup opening 21 and the base station suction port 41 correspond. The dust cup opening structure 1 may include a dust cup cover 11 and a dust cup cover release mechanism 13.

[0036] The dust cup cover 11 is located on the left or right side of the dust cup opening 21. The dust cup cover release mechanism 13 is used to lock the dust cup cover 11 when the vacuum cleaner 3 is not connected to the base station 4, so that the dust cup cover 11 is in a closed state; after the vacuum cleaner 3 is connected to the base station 4, the dust cup cover release mechanism 13 unlocks the dust cup cover 11.

[0037] The dust cup opening 21 can be opened on the side wall of the dust cup 2 and the base station 4. The dust cup opening 21 is used to communicate with the base station suction port 41 for the base station 4 to collect dust and clean.

[0038] In specific implementation, an unlocking structure for unlocking the dust cup cover release mechanism 13 can be set on the base station 4. For example, the dust cup release button 24 can be pushed upward to unlock the protrusion 42, so that after the vacuum cleaner 3 and the base station 4 are docked, the dust cup cover release mechanism 13 is also unlocked, and the dust cup cover 11 can be opened under the action of external force. After the vacuum cleaner 3 leaves the base station 4, the dust cup release button 24 is reset and falls down to continue locking the dust cup cover 11.

[0039] The dust cup opening structure 1 described above adopts a side opening method, which can be widely used in vacuum cleaners 3 with dust collection base stations 4. It has the advantages of strong versatility, simplicity, reliability and low cost.

[0040] The dust cup opening structure 1 provided in the above embodiment has the following advantages. Since the opening direction of the dust cup cover 11 is lateral axial opening, on the one hand, there is no need to consider the direction of the garbage conveying pipe of the base station 4, which has better versatility, can reduce product development costs, and shorten the development cycle. On the other hand, the dust cup cover 11 opens from the side, and its opening angle is not affected by airflow. It can be fully opened when collecting dust, which reduces the probability of garbage residue in the dust cup 2.

[0041] In one embodiment, the dust cup cover 11 is hinged to the dust cup opening 21 via a pivot 12. The pivot 12 is equipped with an elastic reset member, which is used to drive the dust cup cover 11 to elastically reset and close after it is opened. Preferably, the elastic reset member is a torsion spring 14, which is wound around the pivot 12, with one end of the torsion spring 14 connected to the end of the dust cup cover 11 near the pivot 12. The torsion spring 14 has a stable structure, is readily available, and has low cost, thus helping to reduce product costs.

[0042] As another embodiment of this invention, the dust cup cover 11 is made of soft rubber elastic material so that after the dust cup cover 11 is opened, it automatically resets and closes under the elasticity of the soft rubber elastic material itself. That is, the dust cup cover 11 completes the opening and closing action according to its own elasticity, and the structure is simpler.

[0043] The working principle of the dust cup opening structure 1 described above is as follows: When the vacuum cleaner 3 is not placed in the base station 4, the dust cup cover 11 is locked by the dust cup release button 24 and is in a closed state, with the inside of the dust cup 2 being a closed cavity; after the vacuum cleaner 3 is placed in the base station 4, the protrusion 42 of the base station 4 pushes the dust cup cover release mechanism 13 upward, unlocking the dust cup cover 11; the suction fan inside the base station 4 starts, and the dust cup cover 11 is sucked open by negative pressure, thus opening the cover; then, the base station 4 cleans the debris in the dust cup 2, i.e., dust collection and cleaning. Figure 6 The middle arrow indicates the airflow direction in the base station's waste conveying pipe; after cleaning is completed, the suction fan stops working, and the dust cup cover 11 automatically resets and closes under the action of the elastic reset component or its own elasticity. After the vacuum cleaner 3 is removed from the base station 4, the dust cup cover 11 completes self-locking.

[0044] In this embodiment, as Figure 7 and Figure 8 As shown, the dust cup cover release mechanism 13 includes a key cover 131 and a movable key. The movable key includes an upper baffle 132, a locking part 133, and a lower baffle 134 connected sequentially from top to bottom. The upper end of the upper baffle 132 extends into the gap between the key cover 131 and the side wall of the dust cup 2, and moves up and down in the gap under the action of the locking part 133. When the dust cup cover release mechanism 13 is in the locked state, the lower baffle 134 is located in front of the dust cup cover 11 to prevent the dust cup cover 11 from opening outward. The base station 4 is provided with a protrusion 42 that cooperates with the locking part 133. Figure 7 and Figure 8 The middle arrow indicates the direction of movement of the dust cup cover release mechanism.

[0045] Furthermore, a spring 135 is provided between the upper baffle 132 and the side wall of the dust cup 2. One end of the spring 135 is fixedly connected to the upper end of the key cover 131, and the other end is connected to the upper end of the locking part 133, so as to facilitate the reset of the dust cup cover release mechanism 13.

[0046] Among them, the key cover 131 can protect the movable key body; the upper baffle 132, the locking part 133 and the lower baffle 134 can be integrally formed structures. The shape of the locking part 133 is not limited. It can be a triangular locking part, a rectangular locking part or other shapes, as long as it can cooperate with the protrusion 42 on the base station 4. When the vacuum cleaner 3 is placed into the base station 4, it can be pushed upward by the protrusion 42 of the base station 4 to unlock the dust cup cover 11.

[0047] Specifically, when the vacuum cleaner 3 is placed into the base station 4, the locking part 133 is pushed upward by the protrusion 42 of the base station 4, the spring 135 is compressed, the lower baffle 134 moves upward until it no longer blocks the dust cup cover 11, and the dust cup cover 11 is unlocked; when the vacuum cleaner 3 is removed from the base station 4, the protrusion 42 moves downward, the spring 135 returns to its original position and extends, the lower baffle 134 gradually moves downward until it completely blocks the dust cup cover 11, and the dust cup cover 11 is locked again.

[0048] In this embodiment, the dust cup 2 is provided with an installation guide groove 22, and the base station 4 is provided with an installation guide protrusion; the installation guide groove 22 and the installation guide protrusion are slidably engaged, and the dust cup 2 and the base station 4 are connected by the cooperation of the installation guide groove 22 and the installation guide protrusion.

[0049] In another embodiment, the present invention provides a dust cup 2, which includes a dust cup opening structure 1 as described in any of the above embodiments. The dust cup 2 in this embodiment adopts the aforementioned dust cup opening structure 1. Since the opening direction of the dust cup cover 11 is lateral axial opening, there is no need to consider the direction of the waste conveying pipe of the base station 4, resulting in better structural versatility, reduced product development costs, and a shorter development cycle. Simultaneously, the dust cup cover 11 opens from the side, and its opening angle is not affected by airflow, allowing it to be fully opened during dust collection, thus reducing the probability of waste residue in the dust cup 2.

[0050] In this embodiment, the dust cup 2 may also be provided with a dust cup cover 23 and a dust cup release button 24. The dust cup release button 24 is used to open the dust cup cover 23 when the vacuum cleaner 3 is not connected to the base station 4, so as to achieve another way of cleaning the dust cup 2.

[0051] The dust cup 2 has an opening larger than the dust cup mouth 21. This opening is sealed by the dust cup cover 23. The dust cup cover 23 is hinged to one side of the opening of the dust cup 2 via a cover pivot. Components such as the dust cup mouth 21 and the dust cup cover 11 can be provided on the dust cup cover 23.

[0052] In specific implementation, the dust cup cover 23 may be provided with a slot for manual opening by the user, or an elastic element may be provided on the cover pivot to provide a driving force for opening the dust cup cover 23 outward around the cover pivot.

[0053] The dust cup release button 24 is a button with a locking component attached to its body. The upper end of the locking component locks onto one side of the dust cup cover 23. When the dust cup release button 24 is pressed, the locking component moves backward and downward, no longer locking the dust cup cover 23. The user can then manually open the dust cup cover 23, or the elastic component will cause the dust cup cover 23 to open automatically outward.

[0054] In another embodiment, the present invention provides a vacuum cleaner 3, which includes a dust cup 2 as described in any of the above embodiments. The vacuum cleaner 3 in this embodiment uses the aforementioned dust cup 2 and can be used in conjunction with a base station 4. During the processes of placing the vacuum cleaner 3 into the base station 4, collecting dust, cleaning, and removing it from the base station 4, the vacuum cleaner 3 can automatically complete the unlocking, opening, dust collection, and self-locking actions of the dust cup 2. The structure is highly versatile, avoids dust residue in the dust cup 2, is simple and effective, highly reliable, low-cost, and effectively improves the user experience.

[0055] Based on the above embodiments, this embodiment also provides a base station 4, which is used to connect to the vacuum cleaner 3 in the above embodiments. The base station 4 is provided with a base station suction port 41 corresponding to the position of the dust cup opening 21. The base station may also be provided with a protrusion 42 for unlocking the dust cup cover release mechanism 13. The base station 4 provided in this embodiment can connect to the vacuum cleaner 3, conveniently realizing dust collection and cleaning and unlocking of the dust cup cover 11. It has a simple and reliable structure and is easy to use.

[0056] The other components and operations of the dust cup opening structure 1, dust cup 2, vacuum cleaner 3, and base station 4 according to the embodiments of this utility model are known to those skilled in the art and will not be described in detail here.
