[0019] With reference to Fig. 1 to Fig. Figure 7 shows a preferred embodiment of the present application.
[0020] The vacuum cleaner provided by the present application comprises a main body 100, wherein the main body 100 has a vacuum chamber 301 and a blower 400 is arranged in the main body 100; wherein the blower 400 drives an external airflow into the vacuum chamber 301 to achieve a vacuuming effect.
[0021] The vacuum cleaner provided above uses a 400 blower to create a vacuum, allowing external debris to be quickly sucked into the 301 dust collection chamber and collected. The vacuum cleaner features a simple structure and user-friendly operation, efficiently performing waste cleaning tasks and meeting waste collection requirements such as daily cleaning, small work areas, etc.
[0022] More precisely, the main body 100 has a first air opening 10 and a second air opening 20. An air duct 30 is formed between the first air opening 10 and the second air opening 20. The vacuum chamber 301 is arranged in the air duct 30, and the blower 400 is placed in the air duct 30. The blower 400 serves to drive an airflow through the first air opening 10 into the vacuum chamber 301 and then expel it through the second air opening 20. The arrangement of both the vacuum chamber 301 and the blower 400 in the air duct 30 clearly defines the flow path of the airflow and the debris.The structured design of the air duct 30 makes the airflow movement more directed and stable and avoids the problem of reduced dust suction due to airflow turbulence; at the same time, the blower 400 placed in the air duct 30 can directly drive the airflow towards a directed flow, further increasing the accuracy of the airflow drive and the efficiency of waste adsorption.
[0023] A filter element 320 is arranged at the end of the main body 100 near the second air opening 20. The filter element 320 serves to allow the passage of the airflow and to trap debris and dust. In this way, the airflow is filtered as it exits the main body 100, allowing a clean airflow to pass through and exit smoothly. Debris and dust in the vacuum chamber 301 can be precisely trapped to prevent them from exiting with the airflow through the second air opening 20 and causing secondary contamination, thus ensuring the thoroughness of the cleaning work.
[0024] The main body 100 comprises a housing 200 and a hood 300. The hood 300 is detachably connected to the front part of the housing 200, and the dust collection chamber 301 is located within the hood 300. In this way, the main body 100 is divided into the housing 200 and the detachable hood 300, and the dust collection chamber 301 is located within the hood 300, thus solving the problem of unsatisfactory cleaning and maintenance of the dust collection chamber 301. If a large amount of debris accumulates in the dust collection chamber 301, it is not necessary to disassemble the entire main body 100, but only to remove the hood 300 from the housing 200 for direct cleaning or replacement of the dust collection chamber 301, making operation convenient and efficient. At the same time, the detachable structure also facilitates subsequent individual repair and replacement of the hood 300 or the vacuum chamber 301, reduces the maintenance costs of the device and increases the flexibility of use.
[0025] In a preferred embodiment, a projecting air nozzle 310 is formed at the front end of the hood 300, and the first air opening 10 is arranged on the air nozzle 310. The projecting structure of the air nozzle 310 allows the vacuuming area to be focused on a specific region. Compared to a flat air opening, the projecting air nozzle 310 can more easily penetrate narrow crevices or conform to a cleaning surface, precisely adsorb debris in these hard-to-clean areas, expands the applicable scenarios for the vacuum cleaner, and increases the targeting and thoroughness of the cleaning.
[0026] Additionally, the aforementioned air nozzle 310 can be connected to various air nozzle heads to adapt to different scenarios.
[0027] When the blower 400 rotates backwards, air flows out through the first air opening 10 and is drawn in through the second air opening 20.
[0028] More precisely, a oscillating blade 330 is arranged in the air nozzle 310. The upper end of the oscillating blade 330 is fixed to the air nozzle 310, and the lower end of the oscillating blade 330 forms a free end. When an external airflow carrying debris enters the first air opening 10, the free end of the oscillating blade 330 oscillates to the side of the vacuum chamber 301 to open the vacuum chamber 301. When the debris moves backward in the vacuum chamber 301, the free end of the oscillating blade 330 rests against the inner wall of the air nozzle 310 to close the vacuum chamber 301. This creates a one-way passage function for the vacuum chamber 301, effectively preventing debris from exiting backward through the first air opening 10 and avoiding the recollection of debris that falls during cleaning.
[0029] More precisely, the housing 200 and the hood 300 are detachably connected by a connecting structure, the connecting structure comprising an insert section 210 and an annular groove 302, the insert section 210 is arranged on the front part of the housing 200 and an outwardly projecting insert block 211 is formed on the outer circumferential wall of the insert section 210.
[0030] In the present embodiment, the annular groove 302 is arranged on the rear part of the hood 300, and an irregular groove 303 adapted to the insert block 211 is formed on the side wall of the annular groove 302; after the insert section 210 is inserted into the annular groove 302, the hood 300 is rotated so that the insert block 211 is clamped into the irregular groove 303 to create a firm connection between the housing 200 and the hood 300.In this way, after inserting the insert section 210 into the annular groove 302, the insert block 211 can be clamped into the irregular groove 303 by rotating the hood 300, making the assembly process simple and quick, requiring no additional tools and facilitating daily operation by the user; moreover, the clamping connection between the irregular groove 303 and the insert block 211 ensures the stability of the connection between the housing 200 and the hood 300, prevents the hood 300 from loosening and detaching due to vibrations during operation of the device, and also ensures the tightness of the connection section to prevent airflow from escaping through gaps and impairing vacuuming efficiency.
[0031] An installation space 201 is formed within the housing 200, and the fan 400 is arranged in this installation space 201. In this way, a separate installation space 201 is provided within the housing 200, and the fan 400 is placed therein, thus ensuring the stability of the fan 400 within the main body 100, reducing the operating noise of the device, and improving the user experience.
[0032] More precisely, in the direction from the first air opening 10 to the second air opening 20, the first air opening 10, the vacuuming chamber 301, the installation chamber 201 and the second air opening 20 are connected one after the other and form the air duct 30.
[0033] Usage process: First, the charge level of the battery 230 is checked; if the charge level is insufficient, the device is charged via the charging port 222; it is confirmed that the cover 300 is firmly connected to the housing 200, the insert section 210 is inserted into the annular groove 302, and the cover 300 is rotated to ensure that the insert block 211 is fully clamped into the irregular groove 303 to prevent loosening during use.
[0034] During use, the user grasps the handle 220, places their fingers in the finger recess 223, and adjusts the orientation of the air nozzle 310 according to the cleaning requirements: for flat areas such as the floor, table, etc., the air nozzle 310 can be placed against the cleaning surface; for narrow areas such as crevices, corners, etc., the protruding air nozzle 310 is used to penetrate the target area; the switch button 221 on the handle 220 is pressed, the circuit board 500 controls the start of the blower 400, the blower 400 runs stably in the installation space 201 and drives the formation of a negative pressure in the air duct 30.At this point, an external airflow carrying debris enters through the first air opening 10 on the air nozzle 310. The airflow strikes the oscillating blade 330, causing its free end to swing towards the side of the vacuum chamber 301. The vacuum chamber 301 opens, and the debris is carried into the vacuum chamber 301 by the airflow. The airflow then flows to the second air opening 20. As it passes through the filter element 320, debris and dust are captured by the filter element 320, and a clean airflow exits through the second air opening 20. If debris moves backward, the free end of the oscillating blade 330 rests against the inner wall of the air nozzle 310, closing the vacuum chamber 301 to prevent debris from escaping.After cleaning is complete, the switch button 221 is pressed to switch off the blower 400, the hood 300 is rotated so that the insert block 211 is released from the irregular groove 303, the hood 300 is removed, the vacuum chamber 301 and the filter element 320 are cleaned, after cleaning is complete the hood 300 is reassembled and awaited for the next use.
[0035] More precisely, the housing 200 includes a handle 220; a switch 221 and a charging port 222 are arranged on the handle 220, and a circuit board 500 is also arranged in the housing 200, the circuit board 500 being electrically connected to the switch 221 and the charging port 222. In this way, the handle 220 facilitates the use of the product.
[0036] In a preferred embodiment, an inwardly recessed finger groove 223 is formed on the outer surface of the handle 220, the finger groove 223 serving to position and guide the fingers during gripping. In this way, the finger groove 223 can be adapted to the shape of the fingers during gripping, improving gripping comfort and reducing hand fatigue caused by prolonged use.
[0037] More precisely, the circuit board 500 is located in installation space 201.
[0038] The main body 100 houses a 230V battery, which is electrically connected to the 400V blower. This allows the blower to be powered without a mains connection, giving the user flexibility in situations without access to electricity, significantly increasing its mobility and range of use. Alternatively, the main body 100 features a power connector for connecting a power cable, allowing the vacuum cleaner to be plugged into an external power source. This external power source then supplies power to the blower, which is particularly suitable for higher-powered blowers.
[0039] The foregoing description represents only preferred embodiments of the present application and shall not be construed as limiting it. Any modifications, equivalent substitutions, improvements, etc., made in the spirit and principles of the present application shall fall within the scope of protection of the present application.
