Description

Technical Field

[0001] This invention relates to a vacuum cleaner structure with a baffle plate, belonging to the technical field of vacuum cleaner products. Background Technology

[0002] Vacuum cleaners typically use negative pressure to suck dust from the floor into the dust cup. Some vacuum cleaners now come with a dust collection station (dust collection box). After use, the vacuum cleaner can be placed on the dust collection station, which collects the dust. The dust in the dust cup leaks into the dust collection box for temporary storage. The dust collection box is larger than the dust cup and can store a certain amount of dust, eliminating the need to manually empty the dust cup. This further frees up the user's hands, reduces the frequency of vacuum cleaning, and improves the user experience.

[0003] However, traditional dust collection base stations use negative pressure suction to draw the garbage and dust in the dust bin into the dust bag of the dust collection base station. However, current vacuum cleaners and dust collection base stations have problems such as poor sealing, crossflow of air ducts and paths, and dust backflow, resulting in insufficient suction power, more cleaning residue in the base station, high risk of secondary pollution, and poor user experience.

[0004] Current improvements, such as using simple flip-up baffles, still prevent the air intake channel from being completely sealed, leaving gaps and air leaks. Dust in the dust cup can easily flow back into the suction port and air intake pipe, remaining inside the air duct. In vacuuming mode, the exhaust air duct is also prone to crossflow, causing a loss of suction power and a decrease in vacuuming efficiency. Some air duct switching structures lack targeted flow obstruction and guidance designs, resulting in turbulent airflow and severe internal vortices during self-cleaning. Dust can easily swirl and linger in the dead corners of the dust cup, leading to incomplete dust removal. At the same time, turbulence increases wind noise, resulting in a poor overall user experience. Summary of the Invention

[0005] The purpose of this invention is to provide a vacuum cleaner structure with a baffle plate, which can control the opening and closing of the air inlet duct, direct the airflow, prevent dust backflow, and achieve good cleaning effect.

[0006] To solve the above-mentioned technical problems, the present invention provides a vacuum cleaner structure with a baffle plate, including a vacuum cleaner body, a dust collection box arranged on the lower side of the vacuum cleaner body, a dust inlet on the dust collection box, a dust cup in the vacuum cleaner body, a cylindrical filter steel mesh inside the dust cup, an air inlet channel and an air outlet channel inside the vacuum cleaner body, a baffle plate arranged on the air inlet channel, one end of the baffle plate being fixed to the air inlet channel, and the other end being a free end, the dust inlet communicating with the air outlet channel, a recovery baffle plate arranged at the dust inlet, the upper end of the recovery baffle plate being rotatably installed at the dust inlet, and the lower end of the recovery baffle plate being a free end, a dust baffle plate arranged at the entrance of the air inlet channel, one end of the dust baffle plate being rotatably installed at the entrance of the air inlet channel, and the other end being a free end.

[0007] Preferably, the air inlet channel is provided with a protruding structure, which is located below the baffle plate.

[0008] Preferably, when a negative pressure is generated from the upper part of the air inlet channel, the dust baffle rotates under the action of the negative pressure and opens the entrance of the air inlet channel, and air enters the air inlet channel from the entrance of the air inlet channel. The baffle bends upward under the action of the negative pressure to make the air inlet channel unobstructed, and the recovery baffle rotates under the action of the negative pressure and covers the dust inlet.

[0009] Preferably, when air blows downward from the upper part of the air outlet channel, the dust baffle closes to seal the entrance of the air inlet channel, the flow deflector abuts against the protruding structure to close the air inlet channel, the recovery baffle is blown open by the wind to open the dust inlet, and an active bottom plate is hinged at the bottom of the dust cup. When the active bottom plate is opened, the dust in the dust cup and the dust attached to the filter steel mesh flows downward from the air outlet channel and enters the dust collection station box through the dust inlet.

[0010] The beneficial effects of the present invention are: the vacuum cleaner structure with baffle plate of the present invention can control the opening and closing of the air inlet duct, direct the air outlet, prevent dust from flowing back, and has a good dust collection and cleaning effect. The structure is simple and the cost is low. Attached Figure Description

Detailed Implementation

[0012] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Embodiments of the present invention: This invention provides a vacuum cleaner structure with a flow-blocking plate; please refer to [link / reference]. Figures 1 to 2 The system includes a vacuum cleaner body 1, a dust collection box 2 located on the lower side of the vacuum cleaner body 1, a dust inlet 3 on the dust collection box 2, a transparent dust cup 4, and the main body of the vacuum cleaner above the dust cup 4. A cylindrical steel filter mesh 5 is installed inside the dust cup 4. An air inlet channel 6 and an air outlet channel 7 are provided inside the vacuum cleaner body 1. A baffle plate 8 is installed on the air inlet channel 6, with one end of the baffle plate 8 fixed to the air inlet channel. 6. The other end of the flow-blocking plate 8 is a free end. The flow-blocking plate 8 can be a soft rubber sheet. The dust inlet 3 is connected to the air outlet channel 7. A recycling baffle 9 is provided at the dust inlet 3. The upper end of the recycling baffle 9 is rotatably installed at the dust inlet 3. The lower end of the recycling baffle 9 is a free end. A dust baffle 10 is provided at the entrance of the air inlet channel 6. One end of the dust baffle 10 is rotatably installed at the entrance of the air inlet channel 6. The other end of the dust baffle 10 is a free end.

[0014] Preferably, the air inlet channel 6 is provided with a protruding structure 11, which is located below the baffle plate 8.

[0015] When the vacuum cleaner structure with baffle plate of the present invention is working, if the vacuum cleaner is vacuuming, the main unit of the vacuum cleaner is working, and negative pressure is generated in the main unit of the vacuum cleaner and the connected dust cup 4. This negative pressure then extends from the upper part of the air inlet channel 6 to the entire air inlet channel 6. Under the action of negative pressure, the dust baffle 10 rotates and opens the inlet of the air inlet channel 6, allowing air to enter the air inlet channel 6 from the inlet. Under the action of negative pressure, the baffle plate 8 bends upward and no longer blocks the air inlet channel 6, making the air inlet channel unobstructed. The recovery baffle 9 rotates under the action of negative pressure and covers the dust inlet 3. External dust enters the air inlet channel 6 with the air from the inlet. The dust passes through the air inlet channel 6 and the filter steel mesh 5 and enters the dust cup 4 for temporary storage. If the vacuum cleaner is blowing air, the dust temporarily stored in the dust cup 4 is blown into the dust collection box 2. The motor in the dust collector operates in reverse, blowing air downwards from the upper part of the exhaust duct 7. The dust baffle 10 closes, sealing the entrance of the air inlet duct 6. The flow deflector 8 is blown downwards and presses against the protruding structure 11, sealing the air inlet duct 6 (the outer edge of the flow deflector 8 seals the inner wall of the air inlet duct 6). The recovery baffle 9 is blown open by the air, opening the dust inlet 3. The bottom of the dust cup 4 is hinged with an active bottom plate 12, which is opened by a corresponding button (a mature structure exists in the prior art and will not be described here). Dust leaks out from the dust cup 4, including dust adhering to the filter steel mesh 5, flowing downwards from the exhaust duct 7 and through the dust inlet 3 into the dust collection box 2, achieving dust collection in the dust collection box 2. This eliminates the need for frequent removal of the dust cup 4 for separate cleaning, improving user convenience and experience. The flow deflector 8 blocks the airflow, preventing dust from flowing back into the air inlet duct during dust collection, resulting in good dust collection and cleaning effect, simple structure, and low cost.

[0016] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
