The main body 1 is provided with a blade 4 which can cut off the hair etc. on the roller brush 1013 of the vacuum cleaner placed on the charging stand 102 . At this time, the charging stand 102 not only has the function of charging, but also can clean the hair etc. wound on the roller brush 1013, thereby expanding the function of the charging stand 102, and also facilitates the cleaning of the roller brush 1013, simplifying the cleaning of the roller brush 1013. 1013's cleanup process. Here, it should be noted that when the cleaning function of the charging stand 102 is used, the vacuum cleaner can be the rechargeable vacuum cleaner 101 or other types of vacuum cleaners.

The pedal 2 is arranged on the body 1, and the pedal 2 is pivotable between the first position and the second position. An opening 21 is formed on the pedal 2 at a position corresponding to the blade 4. When the pedal 2 is in the first position, the blade 4 is in the Below the opening 21, when the pedal 2 is in the second position, the blade 4 stretches out of the opening 21 so as to cut off the hair on the roller brush 1013 in the vacuum cleaner placed on the pedal 2. When the pedal 2 is at the above-mentioned first position, the blade 4 is accommodated in the main body 1 and is not exposed from the opening 21. At this time, the rechargeable vacuum cleaner 101 can be placed on the charging stand 102 to realize charging, and the charging stand 102 is guaranteed. safety. When the pedal 2 was at the above-mentioned second position, the blade 4 stretched out from the opening 21, and now the vacuum cleaner was started to rotate the roller brush 1013, so that the blade 4 could effectively cut off the hair etc. wound around the roller brush 1013.

Optionally, the blade 4 extends linearly in the length direction of the blade 4, thus, the processing is simple and the cost is low. Of course, the blade 4 can also extend in an arc along its length direction, thus, in the process of cutting hair, the stability of the blade 4 can be effectively guaranteed, so that the hair cutting effect of the blade 4 is better. For example, referring to FIG. 3 , the blade 4 is bent toward a direction away from the main body 1 , so that the hair wrapped around the roller brush 1013 can be better cut off.

Specifically, with reference to Fig. 3 and in conjunction with Fig. 4, the knife edge extends along the left-right direction, the length direction of the blade 4 is the same as the above-mentioned extension direction, and the length direction of the blade 4 is preferably the same as the length direction of the roller brush 1013, thus, the blade 4 can be The hair on the roller brush 1013 is more fully cut off.

When the pedal 2 is stepped down, the rear end of the pedal 2 is upward. Tilt up and touch the micro switch, so that the micro switch can cut off the charging function of the charging stand 102, stop charging the rechargeable vacuum cleaner 101 placed on the pedal 2, and send a signal to the rechargeable vacuum cleaner 101 to make it work. Rolling brush 1013 rotates, and blade 4 realizes cutting hair. Here, it should be noted that the specific structure and working principle of the micro switch are existing and will not be described in detail here.

According to some embodiments of the present invention, as shown in FIGS. An elastic return member 23 is provided between the second end of the body 1 and the elastic return member 23 is configured to always push the pedal 2 toward the first position, that is, the pedal 2 is always kept at the first position. Optionally, the elastic reset member 23 is a spring.

For example, as shown in Figures 5-8, the pedal 2 extends in the front-rear direction, the above-mentioned first end of the pedal 2 is the rear end of the pedal 2, the above-mentioned second end of the pedal 2 is the front end of the pedal 2, and the rear end of the pedal 2 The pivot shaft 22 extending in the left-right direction is pivotably connected to the body 1, and the elastic return member 23, such as a spring, is arranged at the front end of the pedal 2 and between the lower surface of the pedal 2 and the bottom wall of the body 1. The elastic return member 23 Push the pedal 2 up and down to keep the pedal 2 in a horizontal position.

Further, a limiting member 24 is provided on a side of the body 1 adjacent to the second end of the pedal 2 , and the limiting member 24 is located on a side of the pedal 2 away from the elastic reset member 23 . For example, as shown in FIGS. 5-8 , the stopper 24 is a baffle, and the baffle is arranged on the front side of the body 1 and abuts against the upper surface of the pedal 2 , so that the pedal 2 can be prevented from resting on the elastic reset member 23 . continue to rotate upwards.

As shown in FIG. 7 , when the rechargeable vacuum cleaner 101 needs to be charged, the rechargeable vacuum cleaner 101 can be directly placed on the pedal 2 of the charging stand 102 for charging. When the hair needs to be cut, after the vacuum cleaner is placed on the pedal 2, the front part of the vacuum cleaner can be pressed down to drive the front end of the pedal 2 to move downward, so that the blade 4 can be inserted from the opening 21 of the pedal 2, and the vacuum cleaner can be started Roller brush 1013 rotates (for example, can realize by above-mentioned micro switch), realizes cutting hair, as shown in Figure 8. Thus, by setting the above-mentioned charging stand 102, automatic hair cutting is realized, and the user can realize hair cutting without disassembling the roller brush 1013, thereby greatly facilitating the user.

According to some embodiments of the present invention, the top of the body 1 is open, the pedal 2 is arranged in the body 1, the upper surface of the pedal 2 is lower than the upper end surface of the body 1, and the bottom wall of the pedal 2 and the body 1 is spaced apart from each other, the pedal 2 An accommodating space is defined between the body 1 and the blade 4 , the elastic reset member 23 and the like can be placed in the accommodating space.

Specifically, as shown in Figure 9, each safety protection device 3 includes: a safety protection member 31 and a reset member 32, the safety protection member 31 is arranged on the side of the pedal 2, and the safety protection member 31 is formed with a The matching groove 311 for edge fit, the reset member 32 is arranged between the safety protection member 31 and the body 1 , the reset member 32 is configured to push the safety protection member 31 toward the center of the pedal 2 . Optionally, the reset member 32 is a shrapnel or a spring. Thus, by setting the safety protection member 31, the matching groove 311 on the safety protection member 31 can cooperate with the edge of the pedal 2 to prevent the pedal 2 from moving to the second position and the blade 4 is exposed. Moreover, by setting the reset member 32, When no external force acts on the safety protection member 31 , the safety protection member 31 can make the matching groove 311 cooperate with the edge of the pedal 2 under the action of the reset member 32 to realize the safety protection function.

As shown in FIG. 9 , the safety protection member 31 is pivotally connected to the body 1, and the safety protection member 31 has a first end (for example, the upper end in FIG. 9 ) and a second end (for example, the lower end in FIG. 9 ). , wherein the matching groove 311 is formed at the second end of the safety protection member 31, and when the first end of the safety protection member 31 is toggled, the second end of the safety protection member 31 moves in a direction away from the center of the pedal 2 so that the edge of the pedal 2 It is disengaged from the matching groove 311 .

For example, under normal circumstances, the safety protector 31 is vertically arranged, and the side of the matching groove 311 is open toward the center of the pedal 2 and cooperates with the edge of the pedal 2. The inner wall of 311 stops, so that the pedal 2 cannot move to the second position, that is, the blade 4 cannot protrude from the opening 21, which improves safety. When hair needs to be cut, for example, the first end of the safety protector 31 can be moved downwards, while the matching groove 311 of the second end of the safety protector 31 moves in a direction away from the pedal 2 and separates from the pedal 2. Lower the pedal 2, the pedal 2 can move to the second position, so that the blade 4 stretches out of the opening 21 to realize cutting hair.

As shown in FIG. 9 , when the pedal 2 is at the first position, the first end of the safety protection member 31 protrudes from the inner surface of the body 1 and is located above the pedal 2 . Thus, it is convenient to toggle the first end of the safety protection member 31 .

Further, the first end of the safety protection member 31 has a guide surface suitable for dialing the first end of the safety protection member 31 . Optionally, the guide surface is configured to extend obliquely toward the center of the pedal 2 from top to bottom. For example, the guide surface is formed as an inclined plane or an inclined curved surface extending obliquely toward the center of the pedal 2 from top to bottom. Thus, during the process of putting the vacuum cleaner into the charging base 102 from top to bottom, the side of the vacuum cleaner can push the first end of the safety protection member 31 downward along the guide surface to disengage the pedal 2 from the safety protection member 31 .

Here, two safety protection devices 3 are taken as an example for illustration. When the charging base 102 is not charging, the safety protection parts 31 of the two safety protection devices 3 cooperate with the edge of the pedal 2 under the action of the reset part 32. Even if the pedal 2 is stepped down, the pedal 2 cannot move to the second position. , that is, the blade 4 cannot protrude from the opening 21. And when only promoting a safety protection device 3 and when this safety protection device 3 disengages with the edge of pedal 2, because another safety protection device 3 still keeps cooperating with the edge of pedal 2, now pedal 2 can't move to the 2nd pedal equally. The second position ensures the safety of the charging stand 102 . When charging the rechargeable vacuum cleaner 101 or cutting the hair of the vacuum cleaner, the vacuum cleaner can be put into the charging stand 102. 2 is disengaged, the rechargeable vacuum cleaner 101 can be charged at this time, if the pedal 2 is stepped down and moved to the second position, the blade 4 stretches out of the opening 21 on the pedal 2, and the hair can be cut at this time. Therefore, by providing the above-mentioned safety protection device 3 , when charging is not in progress, accidental touches can be prevented from causing potential safety hazards.

Further, a blocking piece 5 is provided on the pedal 2, and an opening 21 is formed on the blocking piece 5, and the blocking piece 5 is suitable for being arranged adjacent to the floor brush opening of the floor brush 1012 of the vacuum cleaner. For example, referring to FIG. 10 and FIG. 11 , the baffle 5 is arranged below the floor brush opening, and the distance between the baffle 5 and the floor brush opening is relatively small. An opening 21 is formed on the blocking piece 5 at a position corresponding to the blade 4 , and the blade 4 is adapted to pass through the opening 21 to cut off the hair wound on the roller brush 1013 of the vacuum cleaner. Thus, when the blade 4 is working, the cut hair thrown out by the roller brush 1013 will fall on the blocking plate 5, and will not exceed the dust collection range of the vacuum cleaner, thereby preventing the above-mentioned cut hair from falling in the range that the vacuum cleaner cannot suck. secondary pollution caused.

For example, when the blade 4 is working, the upper end of the blade 4 passes through the opening 21 and contacts the boss of the roller brush 1013 to cut off the hair wound on the boss of the roller brush. A part of the cut hair is directly sucked into the dust cup of the vacuum cleaner by the vacuum cleaner, and another part of the above-mentioned cut hair is thrown out by the roller brush 1013 and falls on the blocking plate 5, and then sucked into the dust cup by the vacuum cleaner.

Optionally, the blocking sheet 5 may be a soft rubber blocking sheet 5, but not limited thereto. For example, the blocking piece 5 can also be a hard plastic blocking piece 5, etc., as long as it can ensure that the hair thrown out by the roller brush 1013 falls within the dust collection range of the vacuum cleaner, the present invention does not specifically limit this.

Further, an elastic member 6 is provided between the blade 4 and the inner wall of the body 1 . Optionally, the elastic member 6 is soft rubber, but not limited thereto. Thus, during the working process of the blade 4, when the blade 4 interferes too much with the rotating brush boss, the height of the blade 4 can be automatically adjusted by the elastic member 6, so that the blade 4 will not be in contact with the roller brush boss Many, thereby greatly reducing the positioning accuracy of the blade 4, reducing the cost, and improving the product qualification rate.

According to some embodiments of the present invention, the elastic member 6 is arranged between the blade 4 and the knife holder 41 and/or between the knife holder 41 and the inner wall of the body 1 . Specifically, the elastic member 6 can only be arranged between the blade 4 and the knife rest 41, or can only be arranged between the knife rest 41 and the inner wall of the body 1, or can also be arranged between the blade 4 and the knife rest 41 at the same time. Between the tool holder 41 and the inner wall of the body 1 . For example, referring to FIGS. 5-8 , the elastic member 6 is disposed between the knife holder 41 and the inner wall of the body 1 , and the upper end of the elastic member 6 is connected to the lower end of the knife holder 41 .

Specifically, when the elastic member 6 is disposed between the tool holder 41 and the inner wall of the body 1 , a receiving groove for receiving the elastic member 6 is formed on the inner wall of the body 1 . Referring to FIGS. 5-8 , the receiving groove may be formed by indenting a part of the inner wall of the body 1 toward a direction away from the center of the body 1 . Thus, the installation and removal of the elastic member 6 is facilitated, and the position of the elastic member 6 can be stabilized.
