In the following, a ground brush 1 for a vacuum cleaner (not shown in the drawings) according to embodiments of a first aspect of the present disclosure will be described with reference to FIG. 1 to FIG. 4.
As shown in FIG. 1 to FIG. 4, the ground brush 1 for the vacuum cleaner according to the embodiments of the first aspect of the present disclosure includes a ground brush body 10, a brushroll cover 20, a brushroll assembly and a microswitch 40.
With reference to FIG. 1 and FIG. 3, the brushroll cover 20 is disposed on the ground brush body 10 in such a manner that the brushroll cover 20 can be opened and closed. The brushroll cover 20 and the ground brush body 10 define a mounting space therebetween, that is, the brushroll cover 20 can be closed on the ground brush body 10 and form the mounting space through cooperation with the ground brush body 10. The brushroll assembly is disposed in the mounting space and provided with a control circuit. The brushroll cover is provided with a triggering part 203 that is configured to cooperate with the microswitch 40.
The microswitch 40 is disposed on the ground brush body 10, electrically connected with the control circuit of the brushroll assembly, and configured to control the control circuit to be turned on or off. The microswitch 40 is disposed on the ground brush body 10, and the triggering part 203 triggers the microswitch 40 to turn on the control circuit when the brushroll cover 20 is closed on the ground brush body 10, and the triggering part 203 releases a trigger action on the microswitch 40 to turn off the control circuit when the brushroll cover 20 is opened.
In the ground brush 1 according to the embodiments of the present disclosure, the triggering part 203 is disposed on the brushroll cover 20 and cooperates with the microswitch 40. When the brushroll cover 20 is closed, the triggering part 203 can trigger the microswitch 40 directly or indirectly to make the brushroll 301 work normally, and when the brushroll cover 20 is opened, the triggering part 203 can release the trigger action on the microswitch 40 to make the brushroll 301 stop working, thus avoiding accidental injury to a user caused by the brushroll 301 if the user opens the brushroll cover 20 by mistake, and improving safety and market competitiveness of a product.
Specifically, the overall brushroll cover 20 can be rotatably connected with the ground brush body 10, and closed or opened through turnover; or the brushroll cover 20 and the ground brush body 10 can be connected in a snapping manner or an inserting manner, that is the brushroll cover 20 can be closed or opened through mounting or dismounting—the overall brushroll cover 20 can be closed on the ground brush body 10, or separate from the ground brush body 10 to be opened.
In some embodiments of the present disclosure, as shown in FIG. 1 and FIG. 3, the brushroll cover 20 includes a cover body 201 and a connecting part. The cover body 201 cooperates with the ground brush body 10 to form the mounting space, and the connecting part is connected between the cover body 201 and the ground brush body 10 to make the cover body 201 connected to the ground brush body 10. The triggering part 203 is disposed on any one of the cover body 201 and the connecting part, that is, the triggering part 203 may be disposed on the cover body 201 or disposed on the connecting part.
In the above embodiments, the brushroll cover 20 includes the cover body 201 and the connecting part, and the cover body 201 cooperates with the ground brush body 10 to form the mounting space to cover the brushroll 301, thus avoiding injury to the user when the brushroll 301 works, and improving safety of the ground brush 1. The brushroll assembly located in the mounting space may be mounted on the cover body 201 or mounted on the ground brush body 10, and preferably, the brushroll assembly is mounted on the ground brush body 10, which is simpler in structure and more convenient to assemble. The connecting part is connected with the cover body 201 and cooperates with the ground brush body 10, and the connecting part is configured to fix the cover body 201 to the ground brush body 10, thus preventing the brushroll cover 20 from separating from the ground brush body 10 and further improving the safety of the ground brush 1.
In some embodiments of the present disclosure, as shown in FIG. 1 to FIG. 4, the connecting part includes a rotating shaft 202, the cover body 201 is rotatingly closed on the ground brush body 10 through the rotating shaft 202, the triggering part 203 is disposed on the rotating shaft 202, and the rotating shaft 202 rotates to make the triggering part 203 trigger the microswitch 40 when the cover body 201 is closed.
In the embodiments, as to a scheme that the brushroll cover 20 is closed on and connected with the ground brush body 10 in a rotating manner, when the brushroll cover 20 is closed on and connected with the ground brush body 10 through rotation of the rotating shaft 202, the triggering part 203 is disposed on the rotating shaft 202. In this way, when the cover body is rotated to be closed, the triggering part 203 also rotates along with the rotating shaft 202 until the cover body 201 is fully closed on the ground brush body 10, and the triggering part 203 also rotates exactly to a position corresponding to the microswitch 40 and triggers the microswitch 40, to turn on the control circuit of the brushroll assembly, thus guaranteeing that the vacuum cleaner can work normally. When the cover body 201 is rotated to be opened, the triggering part 203 also rotates to separate from the microswitch 40, to turn off the control circuit of the brushroll assembly timely, and the brushroll 301 stops working immediately, thus avoiding accidental injury to the user caused by the brushroll 301 and improving the safety of the ground brush 1.
In some other embodiments of the present disclosure, the connecting part includes the rotating shaft 202, the cover body 201 is closed on the ground brush body 10 through rotating of the rotating shaft 202, the triggering part 203 is disposed on the cover body 201, and the triggering part 203 triggers the microswitch 40 when the cover body 201 is closed.
In the embodiments, the connecting part includes the rotating shaft 202, that is the brushroll cover 20 is closed on and connected with the ground brush body 10 in a rotating manner; the triggering part 203 located at the cover body 201 will rotate along with the cover body 201 until the cover body 201 is fully closed on the ground brush body 10, and the triggering part 203 rotates exactly to a position corresponding to the microswitch 40 and triggers the microswitch to turn on the control circuit of the brushroll assembly, thus guaranteeing that the vacuum cleaner can work normally. When the cover body 201 is rotated to be opened, the triggering part 203 also rotates to separate from the microswitch 40, to turn off the control circuit of the brushroll assembly timely, and the brushroll 301 stops working immediately, thus avoiding accidental injury to the user caused by the brushroll 301 and improving the safety of the ground brush 1.
In some more embodiments of the present disclosure, the connecting part includes at least one of a snapping member and an inserting member, through which the brushroll cover 20 is connected to the ground brush body 10, and the triggering part 203 is disposed on the cover body 201.
In the embodiments, the connecting part includes the snapping member and/or the inserting member, that is, the brushroll cover 20 is closed on and connected with the ground brush body 10 in a snapping manner or an inserting manner. Only when the cover body 201 is closed on the ground brush body 10, can the triggering part 203 located at the cover body 201 trigger the microswitch 40, to turn on the control circuit of the brushroll assembly, such that the vacuum cleaner can work normally. When the cover body 201 is separated from the ground brush body 10, the triggering part 203 is separated from the microswitch 40, such that the microswitch 40 returns, to turn off the control circuit of the brushroll assembly timely, and the brushroll 301 stops working immediately, thus avoiding accidental injury to the user caused by the brushroll 301 and improving the safety of the ground brush 1.
In some embodiments of the present disclosure, as shown in FIG. 3 and FIG. 4, when the brushroll cover 20 is closed on the ground brush body 10, the triggering part 203 directly contacts and triggers the microswitch 40.
Further, as shown in FIG. 2 and FIG. 4, the microswitch 40 includes a fixing member 401, a resilient member 402 and a button 403. Specifically, the fixing member 401 is fixed to the ground brush body 10 and connected in the control circuit, the resilient member 402 is disposed on the fixing member 401, the button 403 is disposed on the fixing member 401, and the button 403 is located between the resilient member 402 and the fixing member 401. The triggering part 203 can turn on the control circuit if the resilient member 402 presses the button 403, and when the triggering part 203 is separated from the resilient member 402, the button 403 returns to turn off the control circuit.
Furthermore, the resilient member 402 may be rotatably disposed on the fixing member 401, when the brushroll cover 20 is closed, the triggering part 203 triggers the resilient member 402, such that the resilient member 402 rotates relative to the fixing member 401 and presses the button 403, to turn on the control circuit and enables the brushroll assembly to work normally. When the brushroll cover 20 is opened, the triggering part 203 is separated from the resilient member 402, the resilient member 402 returns to remove a pressure on the button 403, such that the button 403 returns automatically to turn off the control circuit, and the brushroll assembly stops working immediately, thus avoiding accidental injury to the user. Certainly, the present disclosure is not limited thereby; as shown in FIG. 2 and FIG. 4, the resilient member 402 may include a fixing part 4021 and a resilient part 4022. Specifically, the fixing part 4021 has a first end fixed to the fixing member 401, the resilient part 4022 has a first end connected with a second end of the fixing part 4021, and the resilient part 4022 has a second end extending to the button 403. Preferably, as shown in FIG. 2 and FIG. 4, the button 403 is close to a first end of the resilient part 4022.
Optionally, as shown in FIG. 2 and FIG. 4, the resilient member 402 is configured as an L-shaped resilient sheet.
In the above embodiments, the microswitch 40 includes the fixing member 401, the resilient member 402 and the button 403, and the fixing member 401 is coupled with the control circuit of the brushroll assembly. The button 403 can turn on or turn off the control circuit, the control circuit is turned off at a natural state; when the button 403 is pressed, the control circuit is turned on; and when the pressure is removed, the button returns automatically. The resilient member 402 is configured to press the button 403. Specifically, when the brushroll cover 20 is closed, the triggering part 203 applies the pressure on the resilient member 402, and the resilient member 402 deforms resiliently to press the button 403, so as to turn on the control circuit and enable the brushroll assembly to work normally. When the brushroll cover 20 is opened, the triggering part 203 is separated from the resilient member 402, the resilient member 402 returns to remove the pressure on the button 403, so the button 403 returns automatically to turn off the control circuit, and the brushroll assembly stops working, thus avoiding accidental injury to the user.
Certainly, those skilled in the art should understand that the microswitch 40 is not limited to the above structure, and it may be configured as a small button 403 or other structures, as long as having a function like that of the microswitch 40, so those technical schemes are within the scope of the present disclosure.
The resilient member 402 includes the fixing part 4021 and the resilient part 4022, the fixing part 4021 can fix the resilient member 402 to the fixing member 401, thus avoiding displacement of the resilient member 402 and guaranteeing usage reliability of the microswitch 40. The resilient part 4022 is resilient and can deform resiliently to apply a pressing force on the button 403, such that the button 403 can turn on the control circuit. A distance between the resilient member 4022 and a surface of the fixing part 402 is no less than a height of the button 403 at the natural state, thus guaranteeing that the button 403 is located between the resilient member 402 and the fixing member 401.
The button 403 is disposed closed to the first end of the resilient part 4022 connected with the fixing part 4021, and a second end of the resilient part 4022 is relatively far away from the button 403. As to the scheme that the brushroll cover 20 is rotatingly closed, only when the brushroll cover 20 is fully closed on the ground brush body 10, can the resilient part 4022 press the button 403 to a positon where the control circuit is turned on. In the process of rotatingly closing the brushroll cover 20, the button 403 cannot turn on the control circuit, thus avoiding that the brushroll starts working when the brushroll cover 20 is not fully closed, and further improving the safety of the product.
In other embodiments of the present disclosure, the ground brush 1 further includes a driving member which is disposed on the ground brush body 10 and cooperates with the microswitch 40. When the brushroll cover 20 is closed on the ground brush body 10, the triggering part 203 triggers the driving member and triggers the microswitch 40 indirectly through the driving member.
In the above embodiments, the triggering part 203 triggers the microswitch 40 through the driving member, that is when the brushroll cover 20 is closed on the ground brush body 10, the microswitch 40 is not directly but indirectly triggered, which can also accomplish the objective of the present disclosure. Specifically, when the brushroll cover 20 is closed, the triggering part 203 triggers the driving member to apply an acting force on the driving member, such that the driving member moves to trigger the microswitch 40, so as to turn on the control circuit. When the brushroll cover 20 is opened, the triggering part 203 is separated from the driving member, the acting force applied on the driving member is removed, so an acting force on the microswitch 40 applied by the driving member is removed, the microswitch 40 returns to turn off the control circuit.
A vacuum cleaner according to an embodiment of a second aspect of the present disclosure includes the ground brush 1 according to the embodiments of the first aspect of the present disclosure.
Specifically, when the brushroll cover 20 is closed, the triggering part 203 may trigger the microswitch 40 directly or indirectly, to turn on the control circuit of the brushroll assembly, and a driving component drives the brushroll 301 to rotate, such that the brushroll 301 works normally. When the brushroll cover 20 is opened, the triggering part 203 can release a trigger action thereof, the microswitch 40 returns to turn off the control circuit of the brushroll assembly, the driving component stops working, to make the brushroll 301 stop rotating, thus avoiding injury to the user.
It is should be noted that those skilled in the art should understand that the triggering part 203 may be configured as a component individually disposed on the brushroll cover 20 or a part of the brushroll cover 20, both of which can accomplish the function of the microswitch 40 and fall into the scope of the present disclosure.
As the vacuum cleaner according to the embodiments of the present disclosure is provided with the ground brush 1 according to the embodiments of the first aspect, the vacuum cleaner has high safety and will not injure the user if the user opens the brushroll cover 20 by mistake.
To sum up, in the ground brush 1 provided by the present disclosure, the brushroll cover 20 is provided with the triggering part 203, and the triggering part 203 cooperates with the microswitch 40. When the brushroll cover 20 is closed, the triggering part 203 can trigger the microswitch 40 directly or indirectly to make the brushroll 301 work normally; and when the brushroll cover 20 is opened, the triggering part 203 can release the trigger action on the microswitch 40 to make the brushroll stop working, thus avoiding accidental injury to the user if the user opens the brushroll cover 20 by mistake, and improving safety and market competitiveness of the product.
Specifically, as to a present vacuum cleaner, a brushroll is still working when a brushroll cover is opened, which may injure the user accidentally. However, as to the ground brush 1 provided by the present disclosure, the brushroll stops working when the brushroll cover 20 is opened, thus avoiding injury to the user, and improving the safety and the market competitiveness of the product. Specifically, when the brushroll cover 20 is closed, the triggering part 203 can trigger the microswitch 40 directly or indirectly to turn on the control circuit of the brushroll assembly, and the driving component drives the brushroll 301 to rotate, such that the vacuum cleaner works normally; when the brushroll cover 20 is opened, the triggering part 203 can release the trigger action thereof, the microswitch 40 returns to turn off the control circuit of the brushroll assembly, and the driving component stops working to make the brushroll stop rotating, thus avoiding injury to the user.
