DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully deliver the scope of the present disclosure to those skilled in the art.

Embodiment I

[0021] Referring to FIG. 1 to FIG. 2, the present embodiment provides a vacuum cleaner main unit which is firstly provided with a mounting seat 1, a battery 2, a motor 3, and a dust cup 4. The battery 2, the motor 3, and the dust cup 4 are all mounted on the mounting seat 1; the mounting seat 1 is provided with a handle 11 and an air inlet pipe 12; the air inlet pipe 12 is fixedly connected to the handle 11; the motor 3 is detachably mounted on the mounting seat 1; the position of the motor 3 corresponds to the position of the handle 11; the battery 2 is detachably mounted on a first end part of the motor 3; the dust cup 4 is detachably mounted on a second end part of the motor 3; and the position of the dust cup 4 corresponds to the position of the air inlet pipe 12.

[0022] Continuing to refer to FIG. 1 to FIG. 2, the battery 2, the motor 3, and the dust cup 4 are located on the same axial line. The battery 2, the motor 3, and the dust cup 4 are located above the handle 11. The battery 2 and the motor 3 are located right above the handle 11. The dust cup 4 is located right above the air inlet pipe 12. The air inlet pipe 12 is provided with a first air opening 121; and the dust cup 4 is provided with a second air opening 41 matched with the first air opening 121. The first air opening 121 is located on an upper surface of the air inlet pipe 12, and the second air opening 41 is located on a lower surface of the dust cup 4. An air duct is formed among the first air opening 121, the second air opening 41, and a pipe orifice 122 of the air inlet pipe 12, and air enters the dust cup 4 after passing through the air duct.

[0023] The vacuum cleaner main unit provided by the present disclosure mainly includes the handle, the air inlet pipe, the battery, the motor, and the dust cup. The battery and the motor are located right above the handle so that the weight of the machine is uniformly distributed and satisfies the human engineering. The battery, the motor, and the dust cup are located on the same axial line, thus improving the phenomenon that the suction force of the S-shaped air duct is disperse. The air force is direct to a suction inlet so that the suction loss is lower and the suction force is higher. The distance between the dust cup and the pipe orifice of the air inlet pipe is greatly shorter than that in the existing art, so that the dust collection efficiency is improved. The battery and the dust cup are both detachably mounted on the motor and are convenient to assemble and disassemble.

[0024] Therefore, compared to the existing art, the present disclosure has the following advantages:

[0025] 1. The structural layout is reasonable, which satisfies the human engineering.

[0026] 2. The suction loss is low, and the suction power is higher.

[0027] 3. The battery and dust cup are convenient to remove.

Embodiment II

[0028] Referring to FIG. 1 to FIG. 2, a vacuum cleaner main unit provided by Embodiment II of the present disclosure is illustrated. The following technical solution serving as an improvement is further made on the basis of all the above embodiments: The air inlet pipe 12 is provided with a first air opening 121, and the dust cup 4 is provided with a second air opening 41 matched with the first air opening 121. The first air opening 121 is located on an upper surface of the air inlet pipe 12, and the second air opening 41 is located on a lower surface of the dust cup 4. An air duct is formed among the first air opening 121, the second air opening 41, and the pipe orifice 122 of the air inlet pipe 12. An air force enters the dust cup 4 after passing through the air duct. This air duct is of a horn structure. The pipe orifice 122 is an inlet of the air duct, and the second air opening 41 is an outlet of the air duct. The size of the pipe orifice 122 is less than that of the second air opening 41. Therefore, the air speed at the pipe orifice 122 is increased, thus improving the dust collection capacity.

Embodiment III

[0029] Referring to FIG. 1 to FIG. 2, a vacuum cleaner main unit provided by Embodiment III of the present disclosure is illustrated. The following technical solution serving as an improvement is further made on the basis of all the above embodiments: The air inlet pipe 12 is provided with a first air opening 121, and the dust cup 4 is provided with a second air opening 41 matched with the first air opening 121. One arc-shaped stop plate is arranged on each of two opposite sides of the first air opening 121. The two arc-shaped stop plates are respectively wrapped on two opposite side walls of the dust cup 4. On the one hand, the position stability of the dust cup 4 is improved, and on the other hand, leakage of air can be avoided.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present disclosure without departing from the spirit and scope of the present disclosure. Therefore, if these changes and transformations of the present disclosure fall within the scope of the claims of the present disclosure and equivalent technologies of the present disclosure, the present disclosure is intended to include these changes and transformations.
