Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, specifically a vacuum cleaner dust baffle structure that can be opened in both directions. Background Technology

[0002] Existing vacuum cleaner dust cups typically have two openings on their surface. One opening connects to the vacuum cleaner's air intake pipe, serving as the dust cup inlet. This inlet is equipped with a dust baffle that can be flipped to one side while the other side is blocked by the structure. This seals the dust cup inlet when the vacuum cleaner is not running, preventing dust from escaping. When the motor inside the vacuum cleaner is running, the air pressure created by the pressure difference pushes the dust baffle open, allowing dust-laden airflow to enter the dust cup for air filtration and dust collection. The other opening is the dust cup outlet, used to discharge the collected dust and hair. This outlet is usually fitted with a dust cup cover to switch between closed and open states.

[0003] When the vacuum cleaner is in use, the dust-laden airflow is guided into the dust cup by a baffle plate at the dust cup inlet. When the vacuum cleaner is connected to a base station, the dust cup cover opens, and the motor inside the base station operates, extracting the dust and hair from the dust cup and collecting it inside the base station for centralized processing. This structure results in multiple inlets and outlets in the dust cup, making it complex, large in size, and costly in terms of consumables, while also leading to low suction efficiency and low dust removal efficiency from the dust cup.

[0007] The flip-up piece can be flipped in both directions and elastically connected to the outer side of the fixed block.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, 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.

[0031] Example 1:

[0032] Please see Figure 1-3 This utility model provides a technical solution: a vacuum cleaner dust baffle structure that can be opened in both directions, comprising:

[0033] Fixing block 1 is arranged on the inner wall side of dust storage structure 2;

[0034] The flip-up piece 3 can be flipped in both directions and elastically connected to the outer side of the fixed block 1. Its edge is tightly fitted with the inner wall side of the dust storage structure 2 to separate the internal space of the dust storage structure 2. The inner wall side of the dust storage structure 2 is provided with a sealing boss 4 that abuts against the flip-up piece 3. The flip-up piece 3 is a deformable elastic structure.

[0035] The flip-over piece 3 is made of rubber, which improves its deformation and elastic recovery performance.

[0036] The dust storage structure 2 has an inner mounting box 5. The fixing block 1 includes an outer positioning block 6, which is embedded in and positioned in an outer positioning groove 7 on the surface of the mounting box 5. Several inner positioning grooves 9 are provided within the outer positioning groove 7, and an inner positioning post 8 on the inner side of the outer positioning block 6 is inserted and positioned in the inner positioning groove 9. The multi-layered structure consisting of the outer positioning block 6 and the inner positioning post 8 is inserted and positioned into the mounting box 5 to improve assembly strength. The fixing block 1 can also be made of rubber material, allowing it to be embedded in the positioning groove and elastically abut against the inner wall of the positioning groove, thereby further improving installation stability. Alternatively, the fixing block 1 can be positioned on the mounting box 5 using bolts or other fasteners.

[0037] The outer positioning groove 7 is located in the center of the protrusion 10 on the surface of the mounting box 5, and the side of the protrusion 10 forms a wedge-shaped or arc-shaped transition surface. This improves the structural strength of the surface of the mounting box 5 and the mounting location of the fixing block 1, thereby improving the assembly stability of the dust baffle structure. At the same time, when the flip plate 3 flips, the transition surface of the protrusion 10 can form a dust guiding and flow guiding surface together with the surface of the flip plate 3 to improve the airflow efficiency and the dust discharge efficiency when the vacuum cleaner is connected to the base station.

[0038] The working principle of the bidirectionally openable dust baffle structure of this embodiment includes: When vacuuming, the motor inside the vacuum cleaner runs, and the air pressure formed by the pressure difference causes the flip plate 3 to flip towards the filter assembly at the top of the dust storage structure 2, opening the dust baffle inward. The dust-laden airflow enters the dust storage structure 2, and after being filtered by the filter assembly, the dust settles into the groove formed between the inner side of the flip plate 3, the dust storage structure 2, and the mounting box 5; when vacuuming is completed and the motor stops running, the flip plate 3 elastically flips, resets, and assembles on the dust storage structure 2 and the sealing boss 4, thus achieving... The dust collection structure 2 has a partitioned inner cavity, with dust stored at its top, preventing leakage. When the vacuum cleaner connects to the base station to extract dust from the dust collection structure 2, the motor inside the base station operates, causing the pressure difference to push the flip plate 3, causing it to flip in the opposite direction and open outwards. This allows dust to be discharged from the dust collection structure 2 and drawn into the base station. Afterwards, the motor inside the base station stops operating, and the flip plate 3 elastically flips and returns to its original position on the dust collection structure 2 and the sealing boss 4. During this process, the flip plate 3 undergoes elastic deformation under pressure, preventing structural interference. The bidirectional opening design of the dust baffle structure inside the dust collection structure 2 allows for dust intake during vacuuming at the same location as the bottom opening of the dust collection structure 2 and dust discharge when the vacuum cleaner connects to the base station. Furthermore, when the motor is not running, the dust baffle structure partitions the inner cavity of the dust collection structure 2, preventing dust leakage. This simplifies the dust cup structure of the vacuum cleaner, reduces costs, improves the stability of dust storage in the dust cup, and enhances vacuuming and dust removal efficiency, thereby improving the ease of use of the vacuum cleaner.

[0039] Example 2:

[0040] Please see Figure 2 , 3 The figure shows a bidirectionally openable dust baffle structure for a vacuum cleaner according to Embodiment 2 of this utility model. Based on the above embodiments, this embodiment further improves upon the following technical solution: the mounting box 5 slides into the dust storage structure 2, and the guide strip 11 on the inner side of the dust storage structure 2 slides against the mounting box 5. This allows for convenient assembly and disassembly of the dust baffle inside the dust storage structure 2, facilitating replacement of the accessory and ensuring stable performance. In use, the mounting box 5 is guided by the guide strip 11 and pressed into or pulled out of the dust storage structure 2 to assemble or expose the dust baffle for easy assembly and disassembly, thus improving the assembly efficiency of the dust baffle.

[0041] The curved concave edge 12 on the side of the mounting box 5 is tightly fitted with the guide strip 11. The curved structure of the fitting can further improve the guiding stability. The guide strip 11 is tightly fitted with the mounting box 5 to improve the sealing of the structural connection and prevent dust from entering the mounting box 5 through the joint and causing structural contamination.

[0042] In summary, due to the adoption of the above technical solution, the bidirectional opening dust baffle structure of this embodiment has the following advantages compared with the prior art:

[0043] 1. The dust baffle structure and corresponding dust collection structure of this utility model, through the bidirectional opening design of the dust baffle structure inside the dust collection structure, allow for dust intake during vacuuming at the same location when the bottom opening of the dust collection structure is open, and dust discharge when the vacuum cleaner is docked with the base station. Furthermore, when the motor is not running, the dust baffle structure separates the inner cavity of the dust collection structure, preventing dust leakage. This simplifies the dust cup structure of the vacuum cleaner, reduces costs, improves the stability of temporary dust storage in the dust cup, and enhances vacuuming and dust discharge efficiency, thereby improving the ease of use of the vacuum cleaner.

[0044] 2. The dust baffle plate can be easily disassembled and installed within the dust storage structure to facilitate replacement of this component and ensure its stable performance.
