Example one
Referring to fig. 1 to 4, the present invention provides a floor brush for cleaning a surface to be cleaned, which in an exemplary scenario may be used as a floor brush of a hand-held cleaner for cleaning floor debris. It is noted that the floor brush in the above examples is used as a floor brush for a hand-held cleaner, but is only one possible application scenario. In other possible and not explicitly excluded scenarios, the floor brush may also be used as a floor brush for a floor washing machine.
The following will be mainly explained in the context of the use of the floor brush as a floor brush for a hand-held cleaner, the surface to be cleaned being the floor. However, as can be seen from the above description, the scope of the embodiments of the present invention is not limited thereto.
In this embodiment, the floor brush includes a floor brush body 100 and a cyclone generation assembly 200 provided on the floor brush body 100. The floor brush body 100 is provided with a floor brush chamber 110 opened toward a surface to be cleaned, and a cyclone generating assembly 200 is located at an end of the floor brush chamber 110 for generating a cyclone capable of scraping the surface to be cleaned inside the floor brush chamber 110.
Wherein, a suction opening 120 is provided on the wall of the floor brush chamber 110, a dirt intake passage 121 is provided on the floor brush chamber and is communicated with the floor brush chamber 110 through the suction opening 120, the dirt intake passage 121 sucks the garbage in the floor brush chamber 110 into a machine body (not shown) through the suction opening 120.
Specifically, when the floor brush is operated, a suction airflow is generated in a body connected to the floor brush, so that the suction port 120 is in a negative pressure state, and at this time, external air enters the floor brush chamber 110 through a gap between the floor brush body 100 and the floor and the cyclone generating assembly 200. When the external air passes through the cyclone generation assembly 200, the cyclone generation assembly 200 can force the airflow to rotate, such that the airflow flows in a swirling state toward the suction opening 120 and finally enters the dirt intake passage 121 through the suction opening 120. The "vortex state" refers to a cyclone formed by the rotation of the airflow in a clockwise direction or a counterclockwise direction, and is similar to a tornado.
During the movement of the airflow in a swirling state toward the suction opening 120, the rotating airflow (cyclone) scrapes the ground surface, and the garbage in the area of the floor brush chamber 110 is entrained to the vicinity of the suction opening 120, so that the garbage is sucked by the suction opening 120.
Compare with traditional scrubbing brush, the scrubbing brush utilizes the cyclone to clean ground, can solve the tradition on the one hand and directly inhale the problem that type scrubbing brush dust collection efficiency is low on the one hand, and on the other hand can replace traditional electronic round brush, solves the problem that the scrubbing brush that has electronic round brush easily twines the hair, simultaneously, can also simplify the structure of scrubbing brush to reach the purpose that reduces the cost and the weight of scrubbing brush.
In this embodiment, the cyclone generating assemblies 200 are provided in a pair and are disposed at both sides of the suction port 120. The two sides are the two sides of the advancing direction of the floor brush. If the advancing direction of the floor brush is defined as the front, both sides of the advancing direction of the floor brush are the left and right sides of the floor brush, that is, the cyclone generating assemblies 200 are distributed at the left and right sides of the suction opening 120.
Further, the cyclone generation assembly 200 has a rotation direction for driving the airflow to rotate in a predetermined direction, and the rotation direction may be a clockwise direction or a counterclockwise direction. In this embodiment, the cyclone generating assemblies 200 located at both sides of the suction port 120 have opposite rotation directions, for example, when the cyclone generating assembly 200 located at the left side of the suction port 120 has a clockwise rotation direction, the cyclone generating assembly 200 located at the right side of the suction port 120 has a counterclockwise rotation direction, and vice versa. That is, the cyclone generating assemblies 200 located at both sides of the suction port 120 are distributed in a mirror image.
When external air enters the floor brush chamber 110 through the cyclone generating assemblies 200 at both sides, two cyclones are generated in the floor brush chamber 110 and located at both left and right sides of the suction port 120, respectively, and the cyclones move along the floor brush chamber 110 while rotating in the floor brush chamber 110, wherein the cyclone located at the right side of the suction port 120 moves toward the suction port 120 from the right to the left direction, and the cyclone located at the left side of the suction port 120 moves toward the suction port 120 from the left to the right direction.
Specifically, the two cyclones scrape the ground in the floor brush cavity 110, and the garbage entering the floor brush cavity 110 area is conveyed to the vicinity of the suction port 120 to be sucked, and meanwhile, because the two cyclones generally flow towards the suction port 120, namely flow from the side to the center, the dust in the corner areas at the two sides of the floor brush cavity 110 can be conveyed to the vicinity of the suction port 120, and the floor brush cavity has the capability of dust removal along the side, so that the dust removal efficiency is improved, and the floor brush cavity has the advantage of good dust removal effect.
In this embodiment, the floor brush chamber 110 is a conical chamber, and the flow cross section of the floor brush chamber 110 gradually decreases in the direction from the cyclone generating assembly 200 to the suction port 120, so that the cyclone velocity near the suction port 120 is greater than the cyclone velocity at the cyclone generating assembly 200, which is beneficial to sucking and removing the garbage from the suction port and improves the cleaning effect of the cyclone.
In order to facilitate the suction of the garbage from the suction opening 120, the cyclone generated by the cyclone generating assembly 200 makes the airflow close to the surface side to be cleaned flow toward the suction opening 120, so as to facilitate the suction of the garbage from the suction opening 120. On the contrary, if the cyclone generated by the cyclone generating assembly 200 cannot make the airflow close to the surface to be cleaned flow toward the suction port 120, the garbage on the ground is blown away from the suction port 120 by the cyclone, which is not beneficial to the suction port 120 to suck the garbage into the dirty passage 121.
Regarding the cyclone generating assembly 200, in the present embodiment, the cyclone generating assembly 200 is an impeller fixedly disposed on the floor brush body 100. Referring to fig. 2, the impeller includes a central shaft 210, and blades 220 disposed on an outer circumferential wall surface of the central shaft 210 at equal intervals along a circumferential direction of the central shaft 210. The left and right end faces of the floor brush body 100 are provided with mounting holes, and the impeller is fixedly arranged in the mounting holes. One end of the vane 220 is fixed on the outer circumferential wall of the central shaft 210, and the other end is fixed on the inner wall of the mounting hole. An air duct for communicating the brush chamber 110 with the external environment is formed between the adjacent blades 220.
Specifically, the air duct serves to impart a rotary motion to the air flow as the external air passes through the cyclone generating assembly 200, so that the air flow introduced into the floor brush chamber 110 flows in a swirling state toward the suction port 120. Further, the air duct is spiral, and the rotation direction of the air duct is the rotation direction of the cyclone generation assembly 200. Since the cyclone generating assemblies 200 are distributed on the left and right sides of the suction port 120 in a mirror image manner, the cyclone generating assemblies 200 on both sides have opposite rotation directions, for example, one side is a left-handed air duct and the other side is a right-handed air duct.
In this embodiment, the impeller may be fixed on the floor brush body 100 by a fastening member (not shown), such as a nut or a screw, a buckle or a threaded connection. Of course, the impeller may also be integrally formed with the floor brush body 100, and in the present embodiment, the preferred impeller is a part of the casing of the floor brush body 100. Therefore, the number of parts is reduced, and the appearance is beautiful and elegant.
Referring to the structure of the floor brush chamber 110, please continue to refer to fig. 2, in this embodiment, the floor brush chamber 110 is a symmetrical structure, the floor brush chamber 110 has a first chamber 111 and a second chamber 112 that are symmetrically distributed, and the suction opening 120 is symmetrical with respect to a symmetrical plane X of the floor brush chamber 110.
The structure of the floor brush cavity 110 has the following two conditions: in the first situation, please refer to fig. 4, an included angle between the first cavity 111 and the symmetry plane X is a right angle, and the floor brush cavities 110 are linearly distributed; in the second situation, as shown in fig. 1 to fig. 3, an included angle between the first cavity 111 and the symmetry plane X is an acute angle, and the floor brush cavities 110 are distributed in a zigzag shape. It can be understood that, since the floor brush cavity 110 has a symmetrical structure, in the first case, the included angle between the second cavity 112 and the symmetry plane X is also a right angle; in the second case, the angle between the second cavity 112 and the symmetry plane X is also acute.
In the first condition of the floor brush cavity 110, the floor brush body 100 is in a straight strip shape; in the second case, the floor brush body 100 is Y-shaped in the floor brush cavity 110. In this embodiment, the brush body 100 is preferably in a "Y" shape, which is more advantageous for conveying the garbage to the suction port 120.
In this embodiment, please refer to fig. 2, a front edge surface of the opening of the floor brush cavity 110 is recessed upwards to form a plurality of gaps 130, and the gaps 130 are configured to locally increase a distance value between the front edge surface of the bottom of the floor brush and the ground. The "local" can be understood as the gaps 130 are arranged at intervals. Therefore, garbage with larger particles can enter the ground brush cavity 110 through the gap 130 and is sucked by the suction opening 120 under the action of the cyclone.
Further, the bottom of the floor brush is also provided with a first roller 320 and a second roller 310, and the first roller 320 and the second roller 310 are used for driving the floor brush to move on the ground. The first roller 320 is located behind the floor brush chamber 110, and the second roller 310 is located in front of the floor brush chamber 110, wherein the second roller 310 is disposed on the front edge surface recessed with the notch 130.
The number of the first rollers 320 is one, the number of the second rollers 310 is two, and the first rollers 320 and the second rollers 310 form a triangular support, whereby the floor brush has the advantages of smooth and reliable movement.
