As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in FIGS. 1 and 2 , a handheld vacuum cleaner 100 according to an embodiment of the present invention includes a main body 10 , a handle 30 and a power supply structure 50 , wherein the main body 10 is used to implement a vacuuming function, and the handle 30 is connected to The main body 10 is used for the user to hold, and the power supply structure 50 is electrically connected to the main body 10 to supply power to the main body 10 .

Please continue to refer to FIG. 1 and FIG. 2 , the main body 10 includes a dust cup 12 , an air intake pipe 14 , a separation component 16 and a motor component 18 .

Specifically, the dust cup 12 has a substantially hollow cylindrical structure. The dust cup 12 includes an end wall of the dust cup and a side wall of the dust cup extending from the edge of the end wall to the same direction. The side wall of the dust cup surrounds the outer circumference of the end wall of the dust cup. In order to form a dust collecting cavity 121 together with the end wall of the dust cup, the end wall of the dust cup is provided with an air inlet 123 which communicates with the dust collecting cavity 121 . In this way, the airflow carrying dust and sundries in the external environment enters the dust collecting chamber 121 through the air inlet 123 .

The intake pipe 14 has a hollow tubular structure. The intake pipe 14 extends from the edge of the intake port 123 along the central axis of the intake port 123 . Air outlet, and the central axis direction of the air outlet is perpendicular to the central axis direction of the dust cup 12 . In this way, the air flowing in from the air inlet 123 flows along the central axis of the air inlet 123 under the guidance of the air inlet pipe 14, and then flows out in the radial direction of the dust cup 12 through the air outlet to form a spiral air stream.

The central axis direction of the separation assembly 16 is coaxial with the central axis directions of the air inlet pipe 14 and the dust cup 12 , and includes a first-stage separator 161 and a second-stage separator 163 that communicate with each other. The first separation chamber 161 is located in the dust collection chamber 12, one end of the second stage separator 163 is connected to the first stage separator 163 and is located in the dust collection chamber 12, and the other end of the second stage separator 163 protrudes out The dust collection chamber 12 is connected to the motor assembly 18 , and the intake pipe 14 is inserted into the first-stage separator 161 .

In this way, the air flowing out of the air outlet of the air intake pipe 14 spirally flows around the first-stage separator 161, and the dust and sundries in the air flow are separated by the first-stage separator 161 and deposited in the dust cup 12 near the air inlet 123. At one end, the remaining clean air flow enters the second stage separator 163 for further filtration. Since the central axes of the air inlet 123 and the air intake pipe 14 are coaxially arranged with the central axes of the dust cup 12 and the separation assembly 16, the air flow directly enters the interior of the first separator 161 and then flows tangentially to form a spiral air flow, thus making the separation The assembly 16 has a higher separation efficiency, which is different from the prior art where the airflow enters the separation assembly 16 directly from the outside of the separation assembly 16 along the radial direction of the dust cup 12, so it will not cause the dust deposited in the dust cup 12 to be raised. From the above, there is no need to provide a dust shield at the air inlet 123 to prevent dust leakage from the dust cup 12 .

The motor assembly 18 includes a motor housing 181 and a motor body 183 accommodated in the motor housing 181 .

The central axis of the motor body 183 intersects with the central axis of the separation assembly 16, so the airflow flowing out of the separation assembly 16 is turned and then enters the motor body 183. This turning process increases the resistance of the air flowing through, thereby reducing the separation between the separation assembly 16 and the motor. The air flow rate between the main bodies 183 reduces the working noise of the hand-held vacuum cleaner 100 .

Specifically, in some embodiments, the included angle between the central axis of the motor body 183 and the central axis of the separation assembly 16 is greater than or equal to 130° and less than or equal to 175°. When the included angle between the two is less than 130°, the included angle between the motor main body 183 and the separation assembly 16 is too large, which will result in too much difficulty in sealing the gap between the motor main body 183 and the separation assembly 16 . When the angle is greater than 175°, it is difficult to effectively reduce noise.

The central axis of the motor housing 181 intersects with the central axis of the dust cup 12 , and the motor housing 181 extends from one end of the connection and separation assembly 16 to a direction away from the power supply structure 50 . In this way, when the user lifts the handheld vacuum cleaner 100 upward, the motor housing 181 will not interfere with the user's hand, thereby effectively improving the use experience of the handheld vacuum cleaner 100 .

Specifically, in some embodiments, the included angle between the central axis of the motor housing 181 and the central axis of the dust cup 12 is greater than or equal to 130° and less than or equal to 175°. It can be understood that when the angle between the two is less than 130°, the height of the handheld vacuum cleaner 100 will be too large, which is not conducive to the miniaturization of the handheld vacuum cleaner 100, and when the angle between the two is greater than 175°, it will hinder the user. Lift the handheld vacuum cleaner 100 upwards.

In some embodiments, the air outlet 161 is opened on the side wall of the motor housing 181 , so as to prevent the hand-held vacuum cleaner 100 from vacuuming, and the air flow from the air outlet 161 will lift up dust on the ground, and the air outlet 161 is far from the user. The distance is longer, thereby improving the user experience. It can be understood that the position, shape and quantity of the air outlet 161 are not limited, and can be set according to actual needs.

One end of the handle 30 is connected to the dust cup 12 or the end of the separation assembly 16 close to the motor assembly 18 , and the other end of the handle 30 extends away from the main body 10 to be connected to the power supply structure 50 . Since the main body 10 including the separation component 16 and the motor component 18 and the power supply structure 50 are located at both ends of the handle 30 respectively, and the separation component 16 and the motor component 18 are respectively located on both sides of the same end of the handle 30 , compared to connecting the handle 30 to In the solutions such as the motor assembly 18, the distribution of the center of gravity of the hand-held vacuum cleaner 100 of the present application is more balanced, which prevents the weight of the hand-held vacuum cleaner 100 from being concentrated on one side of the handle 30, thereby reducing the use burden of the hand-held vacuum cleaner 100. Not easy to get tired during time use.

The power supply structure 50 includes a power supply structure housing 51 and a battery unit 53 accommodated in the power supply structure housing 51 . A connection surface 512 is formed on the side of the power supply structure housing 51 connected to the handle 30 , and the handle 30 is connected to the middle of the connection surface 512 or the side of the connection surface 512 away from the air inlet 121 . A support surface 514 is formed on the side of the power supply structure housing 51 away from the handle 30. When the hand-held vacuum cleaner 100 is placed on a desktop or other positions, the support surface 514 can be in contact with a surface such as a desktop to play a supporting role.

In one embodiment, the handheld vacuum cleaner 100 further includes a support frame 70, one end of the support frame 70 is connected to the first accommodating section 12, and the other end of the support frame 70 is connected to the connection surface 512 of the power supply structure 50, and the support frame 70 functions The function of further supporting the main body 10 makes the overall structure of the hand-held vacuum cleaner 100 more stable.

The above-mentioned handheld vacuum cleaner 100 has a more reasonable overall layout and distribution of the center of gravity, which prevents the center of gravity of the handheld vacuum cleaner 100 from being concentrated on one side of the handle 30 , making the operation of the handheld vacuum cleaner 100 more labor-saving. Since the air inlet 121 is located on one side of the axial direction of the dust cup 12, the air intake in the tangential direction is realized, so the problems of dust leakage from the dust cup 12 and the poor separation effect of the separation component 16 are effectively solved, and there is no need to install the air inlet at the air inlet. 121 to set the dust shield. Moreover, since the motor body 183 and the dust cup 12 are not coaxially arranged, the gas is diverted into the motor body 183 after passing through the separation assembly 16 , thereby reducing the working noise of the hand-held vacuum cleaner 100 and improving the suction power. In addition, since the motor housing 181 and the dust cup 12 have a certain angle, when the user lifts the handheld vacuum cleaner 100 upward, the motor housing 181 will not interfere with the user's hand, thereby further optimizing the user experience.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.

The above-mentioned embodiments only represent several embodiments of the present invention, and the descriptions thereof are specific and detailed, but should not be construed as a limitation on the scope of the invention patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can also be made, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
