The hand-held vacuum cleaner can include a main body having a suction motor and a dust cup, a handle for the user to hold, a suction nozzle, and a blowing nozzle. The hand-held vacuum cleaner can use the suction nozzle to suck dust on the surface to be cleaned into the dust cup, and use the blowing nozzle to blow dust on the surface to be cleaned away from the surface.
[0024] Reference is made to Figures 1-2 which shows a schematic example of a hand-held vacuum cleaner 100. As shown, the hand-held vacuum cleaner 100 includes a main body 1, a hard handle 2 located at the lower side of the rear of the main body 1, a soft handle 3 located at the middle of the top of the main body 2, a suction nozzle 4 located at the front side of the main body 1, and a blowing nozzle 5 located at the rear side of the main body 1.
[0025] The main body 1 has an elongated shape and has a cylindrical outer contour. The main body 1 extends along a longitudinal axis Y from a front end to a rear end. The suction nozzle 4 and the blowing nozzle 5 are detachably attached at the front end and the rear end of the main body 1, respectively. The longitudinal axis Y passes through the suction nozzle 4 and the blowing nozzle 5.
[0026] In this example, only one type of suction nozzle 4 and one type of blowing nozzle 5 are shown; in practice, the hand-held vacuum cleaner 100 can include a larger number of suction nozzles 4 or blowing nozzles 5; all of which can be individually and detachably attached at the front end and the rear end of the main body 1.
[0027] The hard handle 2 is connected to the main body 1 and is configured for the user's hand to hold. In this example, the hard handle 2 is offset to the lower side of the main body 1, and the hard handle 2 defines a handle center line L, and the included angle α between the handle center line L and the longitudinal axis Y is preferably 45°-135°.
[0028] The soft handle 3 is in contact with the upper part of the main body 1. The soft handle 3 is preferably attached to the middle position of the upper part of the main body 1. The hard handle 2 is located behind the soft handle 3. The soft handle 3 is configured to be able to be manually operated by the user to transform between a storage position in which it is flush with the upper surface of the main body 1 and a carrying position in which it is arched upward relative to the upper surface of the main body 1.
[0029] As Figure 3As shown, the main body 1 includes a main housing 11, a dust collection cup 12, and a suction motor 13. In this example, an exhaust port 131 is also provided at the rear end of the main body 1, and the exhaust port 131 is in fluid communication with the exhaust side of the suction motor 13. The suction nozzle 4 is in fluid communication with the dust collection cup 12, and the blow nozzle is in fluid communication with the exhaust port 131.
[0030] The rigid handle 2 includes a hollow handle housing 21. A battery module 6 is housed inside the handle housing 21. The battery module 6 is electrically connected to the suction motor 13 to provide power to the suction motor 13. An on / off switch 22 is also provided on the outside of the handle housing 21, preferably positioned where it can be triggered by the fingers of the hand holding the rigid handle 2. In some embodiments, a portion of the handle housing 21 and a portion of the main housing 11 are formed as an integral component.
[0031] See Figure 4 The soft handle 3 is sheet-shaped, and each end of the soft handle 3 has a waist-shaped hole 31. The soft handle 3 can be made of rubber, leather, plastic, etc.
[0032] like Figure 5 As shown, a pair of positioning posts 111 are provided on the upper part of the main body 1. A pair of oblong holes 31 of the flexible handle 3 are respectively fitted onto a positioning post 111. A pair of locking blocks 112 are provided on the upper part of the main body 1.

A locking assembly 125 is provided between the upper part of the front portion 122 and the upper front part of the cup body 121. The locking assembly 125 is used to lock and release the front portion 122. The locking assembly 125 includes a trigger switch 1251; when the user presses the trigger switch 1251, the front portion 122 can be opened with one button; this usually occurs when the user empties the debris from the dust cup 12.
[0035] In some embodiments, all or part of the cup 121 and all or part of the main housing 11 are formed as an integral member. In this example, the center line of the cup 121 coincides with the longitudinal axis Y.
[0036] Continuing as shown in Figure 3 The rear portion of the main housing 11 defines a cavity 113 in which the suction motor 13 is mounted. The air intake side of the suction motor 13 faces forward and is in fluid communication with the dust cup 12. The air exhaust side of the suction motor 13 faces rearward and is in fluid communication with the exhaust port 131.
[0037] The rear end portion of the main housing 11 defines the rear end portion of the main body 1. The nozzle 5 is detachably attached to the rear end portion of the main housing 11 and is in fluid communication with the exhaust port 131.
[0038] In some embodiments, the suction nozzle 4 and the blow nozzle 5 are of the same size. In other embodiments, they can be of different sizes and can be removed or replaced from the main body 1 as appropriate.
[0039] When the user operates the hand vacuum cleaner 100, the user can freely choose to hold the rigid handle 2 or the soft handle 3, and when the suction nozzle 4 is aimed at the surface to be cleaned, the debris on the surface to be cleaned can be picked up, and when the blow nozzle 5 is aimed at the surface to be cleaned, the debris on the surface to be cleaned can be blown away to a place where the suction nozzle 4 can easily access, thereby completing the cleaning work.
