Description

A New Handheld Vacuum Cleaner

technical field

The utility model relates to a novel hand-held vacuum cleaner, in particular to a novel hand-held vacuum cleaner with a cyclone device.

Background technique

Hand-held vacuum cleaners have a large market due to their small size, easy to carry and use. They are mainly used for cleaning inside the car, and they also have good effects on keyboards and electrical appliances. But its disadvantage is that the power is small and the suction is not strong enough. If it is used for a long time, it will cause some damage to the motor. Therefore, how to improve the suction strength of the hand-held vacuum cleaner by physical means is the direction of current product development.

In the prior art, the rotary air intake device installed at the air inlet of the vacuum cleaner can improve the suction force of the vacuum cleaner well, but its overall structure is not suitable for small hand-held vacuum cleaners, and the efficiency is low.

Utility model content

Aiming at the present situation of the prior art above, the technical problem to be solved by the utility model is to provide a novel hand-held vacuum cleaner with a simple and compact structure, strong suction, and a high-efficiency rotary air intake device.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a novel hand-held vacuum cleaner, including a body, a motor is arranged in the body, and air inlets and air outlets are respectively provided at both ends of the body, and the air inlet A dust cup is connected, and a filter is arranged in the dust cup. A rotary air inlet device is connected behind the air inlet. The rotary air inlet device has an inlet communicating with the air inlet of the body. The cut surface of the inlet is an inclined plane. The rotary air inlet device has an outlet along the tangential direction of the outer wall, and the outlet is connected with the dust cup, and a filter is arranged in the dust cup, and the filter is connected with the air outlet.

Further, the air outlet is provided with an air outlet plate, and a funnel-shaped through hole is arranged on the air outlet plate, the large end of the through hole communicates with the filter, and the small end of the through hole communicates with the outside world. The setting of the funnel prevents foreign impurities from entering the body.

Further, the cross-section of the outer wall of the air inlet channel where the outlet of the rotating air inlet device communicates with the dust cup is helical in shape, which increases the effect of rotating air inlet.

Further, the rotary air intake device is detachably connected to the machine body, which is convenient for disassembly.

Compared with the prior art, the utility model has the advantages that: the utility model has a compact structure, and a rotary air inlet device is arranged in the air inlet of the vacuum cleaner. It is connected with the dust cup so that after the air enters through the air inlet pipe at the mouth of the machine, the incoming linear wind is converted into spiral wind after passing through the rotating device, and the wind speed is accelerated through the fixed air inlet, and the air enters through the guide angle The wind keeps spiraling around the filter to reduce the burden on the motor. In summary, the new handheld vacuum cleaner has a simple and compact structure, strong suction, and high efficiency, and is suitable for large-scale promotion.

Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

As shown in Figure 1-3, a new type of hand-held vacuum cleaner includes a body 1 in which a motor is arranged, and the two ends of the body 1 are respectively provided with an air inlet 11 and an air outlet 12, and the air inlet 11 is connected with A dust cup 14, the dust cup 14 is provided with a cylindrical filter 15, the rear of the air inlet 11 is connected with a rotary air intake device 13, in order to facilitate the user to disassemble and clean the inside of the vacuum cleaner, the rotary air intake device 13 is provided with The inlet 131 communicated with the air inlet 11 of the body 1, the cut surface of the inlet 131 is a slope, so that the area of the inlet 131 is increased as much as possible, and the rotary air inlet device 13 has an outlet 132 along the tangential direction of the outer wall, and the outlet 132 is connected to the dust The cup 14 is connected, and the cross section of the outer wall of the air inlet channel that the outlet 132 communicates with the dust cup 14 is helical, which increases the effect of rotating the air inlet and reduces the burden on the motor.

Preferably, the dust cup 14 is provided with a filter 15, the filter 15 is connected with an air outlet duct 17, and the air outlet duct 17 communicates with the air outlet 12, and the air outlet 12 is provided with an air outlet plate 16 , the air outlet plate 16 is arranged with a funnel-shaped through hole, the big end of the through hole is connected to the filter 15, the small end of the through hole communicates with the outside world, and the setting of the inverted funnel prevents external impurities from entering the body.
