TECHNICAL FIELD
[0001] The utility model relates to the field of small household appliances, especially a handle rotary folding type micro dust collector. BACKGROUND
[0002] The handheld micro dust collector has become a common daily necessity in modern daily life, and it can be used in a small space such as a car or a sofa without the restriction of a power cord, so it is loved by people.
[0003] The handle of the handheld micro dust collector on the market is fixed or foldable, and the handle can effectively reduce the volume after being folded, facilitating carrying, and reducing logistics costs when the finished product is boxed and shipped. The traditional handle folding methods include middle shaft overturning folding, gear overturning folding, and buckle overturning folding, but all of them have shafts, gears, or buckles in the middle, so the conductive wire must be arranged from the side. In the above-mentioned methods, the conductive wire will bend with the folding movement when folding, and after a long time, the repeated bending will cause the wire to be pulled off, disconnected, or broken, causing accidents such as leakage. Whether it is a middle shaft, a gear, or a buckle, it increases the parts in the handle, increasing the production cost and production process. SUMMARY
[0004] The utility model solves the technical problem by scientifically designing a handle rotary folding type micro dust collector, which comprises a dust collector main body and a rotary handle. The dust collector main body and the rotary handle are connected by a snap ring, the rotary handle and the snap ring are formed by injection molding, and the middle shaft, gear, or buckle is omitted, achieving the beneficial effects of simple structure, convenient assembly, and cost reduction. The center of the snap ring is a through hole, which facilitates the arrangement of the conductive wire, and achieves the beneficial effects of flexibility, practicality, and durability.

The bottom surface of the main handle is set as a 45-degree inclined surface with the front higher than the back. A circular hole is arranged at the center of the inclined surface of the main handle.
[0007] The main shell is set as two symmetrical halves, which are connected and closed by a plurality of screws. The motor is fixedly arranged in the main shell.
[0008] The rotary handle is set as a cylindrical shape similar to the main handle. The top surface of the rotary handle is set as a 45-degree inclined surface with the front higher than the back. A protruding edge with a small upper end is arranged at the center of the top surface of the rotary handle, forming a circular snap ring with a central through hole.
[0009] The lower end of the circular retaining ring on the top surface of the rotary handle is just locked by the central circular hole of the inclined surface of the main handle. The protruding edge of the upper end of the circular retaining ring on the top surface of the rotary handle is located in the cavity at the lower end of the main handle. After being fixed by several screws, they are movably locked together to form a complete vacuum cleaner handle.
[0010] The rotating handle is configured as two symmetrical halves, with the upper inclined surface and the two side end faces of the two rotating handles being connected by several buckles, and a decorative cap is provided at the bottom of the rotating handle.
[0011] An adjustment button is fixedly installed on the upper front side of the rotary handle. A rechargeable battery is installed inside the cavity of the rotary handle. The positive terminal of the rechargeable battery is connected to one end of the adjustment button through a conductive wire. The other end of the adjustment button is connected to the main board on the motor through the conductive wire. The other end of the main board is connected to the negative terminal of the rechargeable battery through the conductive wire. The conductive wire passes through the through hole in the center of the circular retaining ring.
