Description

Technical Field

[0001] The present invention relates to the technical field of electric vacuum cleaners, and in particular to a handheld shuttle-shaped electric vacuum cleaner with integrated blowing and suction. Background Art

[0002] With social progress and rapid economic development, people's living standards have continuously improved, and they are constantly pursuing a higher quality of life. As a household appliance, vacuum cleaners are widely used and widely used in households, leading to constant product updates and expansion of their functions. Currently, small vacuum cleaners with suction and blower functions are widely used for cleaning car interiors and various small spaces in the home.

[0003] However, existing cleaning equipment—vacuum cleaners—are generally only used for vacuuming. They primarily consist of a vacuum cleaner body, an exhaust cover, an exhaust pipe, a vacuum hose, and a nozzle. However, this type of vacuum cleaner is ineffective in deep, steep areas like grooves, slots, and corners, resulting in poor vacuuming and limited applicability. Furthermore, using a dust blower to remove the dirt before vacuuming it is cumbersome, increases the cost of the equipment, and is time-consuming and labor-intensive. Therefore, a compact, easy-to-use, and powerful handheld electric vacuum cleaner with both blowing and suction is needed to address these issues. Summary of the Invention

[0004] The purpose of the present invention is to overcome the problems of the prior art and provide a shuttle-shaped electric vacuum cleaner with blowing and suction that is easy to hold.

[0005] In order to achieve the above object, the present invention adopts the following scheme:

[0006] A hand-held shuttle-shaped electric vacuum cleaner with integrated blowing and suction comprises a vacuum cleaner body, wherein the vacuum cleaner body comprises a first shell, a second shell and a third shell, the second shell being rotatably arranged on the outside of the third shell, the second shell being provided with a first air outlet and a first dust blowing port, the third shell being provided with a second air outlet and a second dust blowing port corresponding to the first air outlet, a switching valve being provided at the first dust blowing port, and a dust blowing nozzle being provided on the switching valve, when the first air outlet is aligned with the second air outlet, the switching valve is closed and air flows out from the first air outlet, and when the first air outlet is staggered with the second air outlet, the switching valve is opened and air flows out from the first dust blowing port to achieve dust blowing.

[0007] Furthermore, the switching valve is arranged in the second shell through a bracket. One end of the bracket is provided with a support bar for articulating the switching valve, and the other end is provided with an arc-shaped plate that fits with the third shell. The shape of the arc-shaped plate corresponds to the outer surface of the third shell. The bracket is arranged between the second shell and the third shell through the arc-shaped plate. The switching valve can rotate outside the third shell following the second shell through the bracket. When the second shell is rotated, the second shell drives the bracket in the first dust blowing port to rotate synchronously. The dust blowing nozzle can be rotated 90° at the first dust blowing port through the switching valve. When the dust blowing nozzle is perpendicular to the shell, the dust blowing nozzle is connected to the first dust blowing port to achieve dust blowing. When the dust blowing nozzle is parallel to the shell, the switching valve cuts off the connection between the dust blowing nozzle and the first dust blowing port.

[0008] Furthermore, the support bar is provided with a hinge hole, and the switching valve is a spherical valve. A rotating shaft is provided on the side of the spherical valve to be inserted into the hinge hole. The spherical valve is hinged to the bracket via the rotating shaft. Positioning arc blocks are provided around the rotating shaft, and the support bar has positioning holes corresponding to the positioning arc blocks. When the spherical valve is fully opened or closed, the positioning arc blocks snap into the positioning holes. The positioning arc blocks and positioning holes allow users to feel a crisp click when rotating the dust blowing nozzle to switch dust blowing modes, improving the user experience.

[0009] Furthermore, the second housing is provided with a rotation limit slot, and the third housing is provided with a limit block that extends into the rotation limit slot. The second housing can rotate relative to the third housing by an angle of 15°-45°. This handheld, shuttle-shaped, integrated blower-suction electric vacuum cleaner can be operated quickly and easily by rotating the second housing to offset the first and second air outlets. Opening the switching valve allows airflow from the first dust-blowing port to achieve dust-blowing mode, making operation simple and quick.

[0010] Furthermore, a negative pressure module, a PCB control board and a power module are provided in the third shell. The PCB control board is electrically connected to the power module. A sealing plate is provided between the PCB control board and the negative pressure module. One end of the negative pressure module is connected to the sealing plate and the other end is connected to the filter element module provided in the first shell.

[0011] Furthermore, a push switch and a USB charging interface are respectively provided on both sides of the third shell, and the push switch and the USB charging interface are both electrically connected to the PCB control board.

[0012] Furthermore, a first sealing ring is provided between the outer side of the sealing plate and the inner side of the third housing, and a second sealing ring is provided between the outer side of the filter module and the inner side of the first housing. These first and second sealing rings effectively enhance the suction generated by the negative pressure module in the product, making the suction more powerful and improving product performance.

[0013] Furthermore, the negative pressure module includes a motor and fan blades. The motor is a three-phase brushless motor with a speed of no less than 80,000 rpm, and the fan blades are aluminum turbine blades. The combination of the high-speed three-phase brushless motor and the turbine blades enables this integrated vacuum cleaner to achieve high suction power in a small size.

[0014] Furthermore, the first shell has a suction port for inserting the dust nozzle. The nozzle insertion end is equipped with a one-way guide plate, one side of which is fixedly connected to the dust nozzle. The simple structure and stable connection effectively prevent the one-way guide plate in the dust nozzle from falling off and causing dust to flow out, thereby improving product stability.

[0015] Furthermore, the vacuum nozzle includes a large vacuum nozzle, a small vacuum nozzle, a long vacuum nozzle, a flannel vacuum nozzle and a brush vacuum nozzle, and the brush vacuum nozzle includes a vacuum nozzle body and a first brush that can slide on the outside of the vacuum nozzle body.

[0016] Compared with existing technologies, the present invention offers the following advantages: This convenient, handheld, shuttle-shaped, integrated blower-suction electric vacuum cleaner can be operated simply and quickly by rotating the second housing to offset the first and second air outlets, and then opening the switching valve to allow air to flow out of the first dust-blowing port. The shuttle-shaped housing, comprised of the first, second, and third housings, fully utilizes its internal space, resulting in a rational design, a compact exterior, and a compact internal structure.

When the first air outlet 201 is staggered with the second air outlet 301, the first dust blowing port 202 and the second dust blowing port are aligned and the switching valve 4 is opened, and air flows out from the first dust blowing port 202 to achieve dust blowing.

[0027] Preferably, Figure 1 As shown, the switching valve 4 is mounted within the second housing 2 via a bracket 6. One end of the bracket 6 is provided with a support bar 601 for articulating the switching valve 4, and the other end is provided with a curved plate 602 that mates with the third housing 3.
