The suction nozzle assembly T2 is installed on the cup shell 1 and defines an air suction channel S1, along the axis direction perpendicular to the air suction channel S1, the air flow generating device 2 and the cyclone separating device 3 are arranged in sequence. Along the axial direction of the suction channel S1, the handle assembly T3 and the suction nozzle assembly T2 are respectively located on both sides of the dust cup assembly T1.

The suction nozzle assembly T2 is mounted on the cup shell 1 and defines a suction channel S1. Referring to FIG. 3 , the suction nozzle assembly T2 can be installed on the front of the cup shell 1 , and an air suction channel S1 is defined in the suction nozzle assembly T2 . One end of the suction channel S1 (for example, the rear end in Figure 3) communicates with the cup shell 1, and the other end of the suction channel S1 (for example, the front end in Figure 3) has a suction port, and dust such as dust can be drawn from the suction channel. The suction port of S1 enters the cup shell 1 .

Along the axial direction perpendicular to the air suction channel S1, the airflow generating device 2 and the cyclone separating device 3 are arranged in sequence. Along the axial direction of the suction channel S1, the handle assembly T3 and the suction nozzle assembly T2 are respectively located on both sides of the dust cup assembly T1. Here, it should be noted that the "vertical" mentioned in this application is understood in a broad sense, that is, vertical in a strict sense is not required.

For example, referring to FIGS. 1-3 , the suction channel S1 can extend along the front and rear directions, the suction nozzle assembly T2 can be installed at the front of the cup shell 1 , and the handle assembly T3 can be installed at the rear of the cup shell 1 . Wherein, the axis of the air intake channel S1 may extend horizontally in the front-rear direction, or may extend obliquely in the front-rear direction. The airflow generating device 2 and the cyclone separating device 3 may be arranged in sequence in a direction perpendicular to the axial direction of the air suction channel S1 or substantially perpendicular to the axial direction of the air suction channel S1 . For example, in the example shown in FIG. 2 , the airflow generating device 2 and the cyclone separating device 3 are arranged sequentially in the axial direction of the cup shell 1 (ie, the up-down direction in FIG. 2 ). Optionally, the air flow generating device 2 may be arranged above the cyclone separating device 3 .

Thus, the airflow channel in the cup shell 1 can be made the shortest and the airflow direction does not change, effectively reducing the loss of vacuum and reducing energy consumption, thereby reducing the volume and weight of the airflow generating device 2, making the dust cup assembly The structure of T1 is more compact, small and regular, which meets the development requirements of the miniaturization of handheld vacuum cleaner T, and is convenient for users to carry. At the same time, the center of gravity of the handheld vacuum cleaner T can be moved forward, reducing the weight of the handle assembly T3, thereby reducing the force required by the user to hold the handheld vacuum cleaner T, which is convenient for the user.

For example, when using a handheld vacuum cleaner T, the user can lift the handheld vacuum cleaner T by holding the handle assembly T3, and then direct the suction port of the suction channel S1 to the place to be cleaned, and then start the airflow generating device 2, when the airflow generating device 2 After being activated, a negative pressure can be generated inside the cup shell 1. At this time, the dust outside the cup shell 1 can be sucked into the cup shell 1 through the suction channel S1, so that it can be cyclone-separated by the cyclone separation device 3, and the separated dust and other garbage The clean air that can be stored in the cup shell 1 and separated can be discharged out of the cup shell 1 , so as to realize the vacuuming and cleaning operation of the handheld vacuum cleaner T.

According to some embodiments of the present invention, the air outlet direction of the air outlet 141 is inclined upward relative to the axial direction of the suction channel S1. Thus, when the user uses the handheld vacuum cleaner T, the clean air discharged from the air outlet 141 can flow obliquely toward the direction away from the suction channel S1, thereby preventing the clean air at the air outlet 141 from being directly blown to the place to be cleaned ( Such as the floor, sofa, etc.), avoiding the clean air from rolling up impurities such as dust in the place to be cleaned, and improving the cleaning efficiency of the handheld vacuum cleaner T.

According to the second embodiment of the utility model for the vacuum cleaner T, the overall performance of the vacuum cleaner T is improved by providing the dust cup assembly T1 according to the first aspect of the utility model.
