The technical solution of the present invention has the following advantages:

1. The wireless handheld vacuum cleaner provided by the present invention adopts a layout structure in which an air intake pipe, a dust cup and a motor are arranged in sequence, wherein the motor is connected to the side wall of the dust cup, the axis of the motor is parallel to the air intake pipe and perpendicular to the center line of the dust cup at the same time, and dust and dirt directly enter the tangent of the side wall of the dust cup from the air intake pipe, which is conducive to dust and dirt separation and ensures dust collection efficiency. At the same time, the motor is parallel to the air intake pipe, so that the vacuum cleaner as a whole is still streamlined, ensuring the overall structure is compact.

2. The cordless handheld vacuum cleaner provided by the present invention has a first gripping handle at one end of the handle connected to the battery, which extends outward along the axis of the battery and is bent in a direction perpendicular to the axis of the battery and the center line of the dust cup. When cleaning the floor, the first gripping handle can be grasped to allow the vacuum cleaner to droop naturally, thereby increasing the working length of the vacuum cleaner and improving the labor-saving and comfort of the vacuuming operation.

3. The cordless handheld vacuum cleaner provided by the present invention has a second gripping handle at one end of the handle connected to the dust cup, which is parallel to the axis of the motor and the axis of the battery.

4. In the cordless handheld vacuum cleaner provided by the present invention, the first gripping handle and the second gripping handle are located in the same plane, so that the first gripping handle and the second gripping handle can be designed as a whole, which is convenient for the production of the product.

5. The cordless handheld vacuum cleaner provided by the present invention has air outlets on the motor at both sides of the second gripping handle, so that no matter whether the first gripping handle or the second gripping handle is held, wind will not blow directly onto the hands, making the design of the vacuum cleaner more reasonable.

6. The cordless handheld vacuum cleaner provided by the present invention has a cyclone separator in the dust cup, and the outlet of the cyclone separator is located at the upper end or the lower end of the dust cup, so that dust and dirt enter from the tangent line of the side wall of the cyclone separator, and are discharged from the outlet at the upper end or the lower end after rotational separation, which is beneficial to the separation efficiency of dust and dirt.

7. In the cordless handheld vacuum cleaner provided by the present invention, the battery is arranged between the dust cup and the motor, and the airflow channel for the airflow from the outlet of the cyclone separator to the inlet of the motor is arranged in the dust cup and the battery. This arrangement does not affect the overall structure of the appearance and the dust collection efficiency of the vacuum cleaner, and can be used as a modified arrangement of the present invention.

8. In the cordless handheld vacuum cleaner provided by the present invention, the inlet of the cyclone separator is connected to the air inlet pipe, so that the dust and dirt airflow can enter the interior of the cyclone separator through the air inlet pipe along the tangent direction of the inner wall of the cyclone separator, so that the dust and dirt can quickly enter and be rotated and separated in the cyclone separator, thereby improving the dust collection efficiency.

9. The cordless handheld vacuum cleaner provided by the present invention has a dust cup and/or a motor and/or a battery of a cylindrical structure, wherein the cylindrical structure of the dust cup can better cooperate with the cyclone separator to accommodate more dust and dirt, the cylindrical shape of the motor is a general form, which can cooperate with the rotor to rotate better, and the cylindrical shape of the battery can cooperate with the motor so that no boss will be generated when the battery and the motor are docked.

10. In the cordless handheld vacuum cleaner provided by the present invention, the outer diameter of the dust cup is larger than the outer diameters of the motor and the battery. Such an arrangement enables, firstly, the motor or the battery to be arranged along the tangent of the side wall of the dust cup when connected to the side wall of the dust cup, thereby preventing the generation of a boss and leaving space for the installation of the handle, thereby making the overall structure of the vacuum cleaner compact. Secondly, the dust cup can hold more dust.

11. In the cordless handheld vacuum cleaner provided by the present invention, the motor, battery and handle are all located inside two tangents of the dust cup side wall parallel to the motor axis, thereby ensuring the compactness of the overall structure of the vacuum cleaner and facilitating storage.
