The handle 7 in this example includes a hand holding portion approximately in the shape of a “9” shown in FIG. 1 and a straight rod connected to the hand holding portion, as shown in FIGS. 3 and 5 .

The body of the vacuum cleaner includes a body body 4, a ground brush 9, a multi-stage cyclone 1 (also known as a multi-stage tornado dust cup), a motor 2 and a battery pack 3. Wherein, the floor brush 9 is detachably connected to the bottom of the fuselage body 4, the multi-stage cyclone 1 is detachably connected to the fuselage body 4, and the top of the multi-stage cyclone 1 is provided with a handle 101 to facilitate the multi-stage cyclone The disassembly, installation and handling of the device 1, the multi-stage cyclone 1 has a dust cup body, the motor 2 is fixed on the fuselage body 4, the battery pack 3 is detachably installed on the motor 2, and the multi-stage cyclone 1 is located on the motor 2 or above the battery pack 3. The motor 2 can be arranged above the battery pack 3 or below the battery pack 3 . When the motor 2 is located above the battery pack 3 , the multi-stage cyclone 1 is arranged above the motor 2 . When the motor 2 is located below the battery pack 3, the multi-stage cyclone 1 is arranged above the battery pack 3. In this example, the motor 2 is located below the battery pack 3, and the multi-stage cyclone 1 is arranged above the battery pack 3, as Figures 1 and 8.

The dust cup of the stick-type vacuum cleaner in this embodiment is a multi-stage cyclone 1 (also called a multi-stage tornado dust cup), thereby optimizing the dust-absorbing effect of the stick-type vacuum cleaner.

The specific assembly method between the battery pack 3 and the motor 2 in this example can be referred to as shown in Fig. 4 and Fig. 8: the upper part of the motor 2 is provided with a battery accommodating groove 201, and the battery pack 3 is arranged in the battery accommodating slot 201. slot 201. In addition, in this example, a plurality of vertically arranged guide grooves 301 are provided on the outer surface of the battery pack 3, and guide ribs 202 slidingly fitted with the guide grooves 301 are formed on the groove wall of the battery accommodating groove 201. . In this way, on the one hand, the installation of the battery pack 3 can be guided and positioned; on the other hand, the battery pack 3 can be prevented from shaking in the battery accommodating groove 201 , as shown in FIG. 4 , FIG. 7 and FIG. 15 .

In this example, the battery pack 3 is electrically connected to the motor 2 to provide working power for the motor, and the battery pack 3 and the motor 2 are electrically connected through a quick plug mechanism. In actual application, the battery pack 3 can be charged first, and then the battery pack 3 can be used to supply power to the motor 2, and the motor 2 runs to generate vacuum suction to suck the dust cleaned by the ground brush 9 into the dust cup in the multi-stage cyclone 1 body. In this way, people do not need to drag the power cord to clean like traditional vacuum cleaners, which is very convenient. In fact, the vacuum cleaner does not need to be equipped with a power cord.

Referring to Figure 4, Figure 13, Figure 14 and Figure 15, in this example, the quick plug-in mechanism is fixed on the battery pack 3 by a circuit board 302 connected to the battery pack 3, fixed on the The socket 303 on the circuit board 302 and connected to the circuit board, and the plug connector 203 fixed on the motor 2 and connected to the motor constitute.

Referring to Figure 6, the rod-type vacuum cleaner in this embodiment is provided with two air inlet ducts and a three-way switch for switching between the two air inlet ducts. The two air inlet ducts are mainly It is jointly formed by the ground brush 9, the handle 7, the hose 8 and the fuselage air intake pipe 403 in the fuselage, wherein one air inlet duct enters the fuselage intake pipe 403 from the ground brush 9, and then enters the multi-stage cyclone 1 The other air inlet duct enters the hose 8 from the handle 7, then enters the air intake pipe 403 of the fuselage, and then enters the dust cup body of the multi-stage cyclone 1. The specific structure is as follows:

The three-way switch is mainly composed of a three-way pipe 11 and a valve 6 rotatably installed in the three-way pipe 11, wherein the three-way pipe 11 is fixed in the vacuum cleaner body. The three-way pipe 11 has three nozzles that communicate with each other, one of which communicates with the floor brush air duct 901 provided in the ground brush 9, and the other nozzle communicates with the hose 8, and the hose 8 communicates with the inside of the handle 7. The provided handle air hole (the handle 7 has a central axis hole communicating with the flexible pipe 8, which forms the handle air hole) is in gas communication, and there is also a nozzle that is in gas phase with the fuselage air intake pipe 403 in the fuselage. The air intake pipe 403 of the fuselage is in air communication with the dust cup body in the multi-stage cyclone 1 . When the valve 6 is rotated to different positions, the ground brush air pipe 901 can be selectively communicated with the air intake pipe 403 of the fuselage, so that the hose 8 and the air intake pipe 403 of the fuselage can be closed in gas phase; The air intake pipe 403 of the fuselage is connected, so that the ground brush air pipe 901 and the air intake pipe 403 of the fuselage are gas-phase closed.

This vacuum cleaner has two working modes. The first working mode: fix the front end of the handle 7 on the vacuum cleaner body, toggle the valve 6 to connect the ground brush air pipe 901 with the air intake pipe 403 of the body, at this time the hose 8 and the air intake pipe 403 of the body are closed in gas phase, Turn on the motor 2 to generate the air flow from the ground brush air duct 901 - the air intake duct 403 of the fuselage - the dust cup in the multi-stage cyclone 1, and the user holds the handle 7 to push the vacuum cleaner to move on the ground, thereby relying on the ground brush 9 The action and the wind flow generated by the motor 2 will sweep the ground dust and suck it into the dust cup body. The second working mode: remove the front end of the handle 7 from the body of the vacuum cleaner (the two are snap-fit connections), toggle the valve 6 to connect the hose 8 with the air intake pipe 403 of the body, and at this time the floor brush The air duct 901 is closed in gas phase with the air intake pipe 403 of the fuselage, and the motor 2 is turned on to generate the air flow from the handle 7—hose 8—air intake pipe 403 of the fuselage—the dust cup in the multi-stage cyclone 1, thus completely relying on the motor 2. The wind flow generated will suck the dust into the dust cup body from the front end of the handle. Because the shape of the end of the handle 7 is very light and small, when the second working mode is adopted, the vacuum cleaner can be used to clean various sanitary corners such as sofas, window sills, and table corners, which is very convenient. In order to optimize the dust collection effect of the second working mode, the user can also install accessories such as a flat suction 5 or a sofa suction on the front end of the handle 7 for dust collection.

The specific connection method between the front end of the handle 7 and the vacuum cleaner body in this example is as follows: the front end of the handle 7 is provided with an engaging hole 701, and the main body 4 is provided with a handle insertion tube 401 with an open top. The handle insertion barrel 401 is made of metal, and a spring buckle 402 matching with the engaging hole 701 is installed on the handle insertion barrel 401 . The specific structure of the spring buckle 402 described in this example is as follows:

As shown in Figure 11 and Figure 12, the spring buckle 402 is composed of an unlocking button 402a, a tongue 402b, a torsion spring shaft 402c and a tongue relief hole 402d, wherein the tongue relief hole 402d is set in the handle insert On the cylinder wall of the release cylinder 401, and the tongue relief hole 402d communicates with the inner cylinder cavity of the handle insertion cylinder 401, the tongue 402b and the unlocking button 402a are integrally structured, and the unlocking button 402a is hinged by the torsion spring shaft 402c On the tongue relief hole 402d, and the torsion spring shaft 402c exerts a twisting force on the unlocking button 402a, and the unlocking button 402a drives the snap tongue connected with it under the action of the torsion force of the torsion spring shaft 402c 402b protrudes into the inner cylinder cavity of the handle insertion cylinder 401 through the tongue relief hole 402d.

When adjusting the vacuum cleaner to the above-mentioned first working mode, the user aligns the front end of the handle 7 with the mouth of the top of the handle insertion cylinder 401 and applies force downward, and the handle 7 is inserted downward into the handle insertion under the action of this force. In the tube 401, when the handle 7 is inserted downward, the front end of the handle 7 pushes the tab 402b in the handle insertion tube 401 to move the tab outward (at this time, the unlock button 402a and the tab 402b are shown in Fig. 6 Rotate counterclockwise around the torsion spring shaft 402c), when the engaging hole 701 at the front end of the handle 7 moves down to the tongue relief hole 402d, the tab 402b is stretched into again under the torsion force of the torsion spring shaft 402c The handle is inserted into the barrel 401 and locked together with the engaging hole 701 on the handle 7 , so that the handle 7 and the fuselage body 4 are fixedly connected together. In order to prevent the hose 8 from swinging greatly, in this example, a hose fixing clip 404 is provided on the fuselage body 4 , and the hose 8 can be stuck on the hose fixing clip 404 .

When the vacuum cleaner is adjusted to the above-mentioned second working mode, the user presses the unlock button 402a with a finger, so that the unlock button 402a rotates counterclockwise around the torsion spring shaft 402c in FIG. 6 , so that the tab 402b moves outward And it is separated from the engaging hole 701 at the front end of the handle 7 , so that the handle 7 is free from the restriction of the spring buckle 402 . Then the user grasps the handle 7 and pulls it upwards, so that the handle 7 can be taken out from the handle insertion tube 401 .

In this embodiment, the specific equipment between the multi-stage cyclone 1, the fuselage body 4 and the battery pack 3 can be referred to as shown in FIG. 10. A lock hook 12 is formed on the fuselage body 4. There is a spring lock 13 matched with the lock hook 12 . The specific structure of the spring lock 13 described in this example is shown in FIG. And a lock hook relief hole 1304 communicating with the chute 1303 transversely (that is, the hole axis of the shackle relief hole is arranged transversely), the lock block 1301 is arranged in the chute 1303 and can slide up and down, the The spring 1302 is vertically arranged in the chute 1303, and the spring 1302 is clamped between the lock block 1301 and the bottom of the chute, and the lock block 1301 is provided with a horizontal (that is, the axis of the locking hole is arranged transversely) locking hole 1305. In order to prevent the spring 1302 from moving in the chute 1303 , a spring positioning post 1306 extending upward is provided at the bottom of the chute 1303 in this example, and the lower end of the spring 1302 is sleeved on the spring positioning post 1306 .

Normally, the locking hook 12 on the fuselage body 4 extends into the locking hole 1305 on the locking block 1301 through the locking hook relief hole 1304, and the locking block 1301 has a tendency to slide upward under the elastic force of the spring 1302, In this way, the hook portion of the locking hook 12 is tightly hooked to the edge of the left end hole of the locking hole 1305 in FIG. 10 , thereby fixing the multi-stage cyclone 1 and the fuselage body 4 together.

When the multi-stage cyclone 1 needs to be removed, the operator presses down the locking block 1301 from the top opening of the chute 1303, so that the locking block 1301 moves down along the chute 1303, at this time the spring 1302 is compressed and becomes shorter, and the locking block The locking hole 1305 on 1301 moves downward relative to the locking hook 12, so that the locking hook 12 is separated from the locking hole 1305, that is, the locking hook 12 no longer hooks the locking block 1301, and then holds the handle 101 in Figure 6 Turn the multi-stage cyclone 1 to the left, so that the lock hook 12 is completely separated from the locking hole 1305, and the multi-stage cyclone 1 can be removed.

If the multi-stage cyclone 1 and the fuselage body 4 are connected together only by the cooperation of the lock hook 12 and the spring lock 13, it is difficult to ensure the stability of the connection between the two. 1 Shaking is likely to occur. In this regard, this embodiment also adopts the following structure: the upper part of the battery pack 3 is covered with a positioning sleeve 14, the upper part of the positioning sleeve is formed with a positioning protrusion 1401, and the bottom of the multi-stage cyclone 1 is formed with a The positioning groove 102 matched with the positioning protrusion 1401 . After the assembly is completed, the positioning sleeve 14 is set outside the battery pack 3 and fixed relatively to the battery pack 3 , and the positioning groove 102 at the bottom of the multi-stage cyclone 1 is stuck outside the positioning protrusion 1401 of the positioning sleeve. In this way, through the cooperation of the above-mentioned lock hook 12 and the spring lock 13, and the cooperation of the positioning protrusion 1401 and the positioning groove 102, the multi-stage cyclone 1 is fixed on the fuselage body 4 jointly, thereby ensuring the multi-stage cyclone. 1 positional stability.

Certainly, the above-mentioned embodiments are only for illustrating the technical conception and characteristics of the present invention, and the purpose is to enable people to understand the content of the present invention and implement it accordingly, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the main technical solutions of the present invention shall fall within the protection scope of the present invention.
