Example one

FIG. 1 is a schematic structural diagram of a floor brush according to an embodiment of the present invention; fig. 2 is a sectional view of a floor brush provided in an embodiment of the present invention. Referring to fig. 1 and fig. 2, the floor brush provided in this embodiment includes: a housing 10, a roll brush 20, and a roll brush cover 40. The drum brush cover 40 is provided above the drum brush 20, and a ventilation hole 41 is provided on the drum brush cover 40, the ventilation hole 41 allowing external air to contact the drum brush 20.

In some embodiments, the floor brush further comprises a running wheel (including front wheel 101 and/or rear wheel 102) to support the surface to be cleaned in cooperation with the roll brush 20 during contact of the floor brush with the surface to be cleaned (e.g., the floor).

Specifically, the roll brush 20 is coupled in the housing 10. The housing 10 and the brush cover 40 may enclose a receiving chamber, and a plurality of floor brush related parts may be disposed in the receiving chamber of the housing 10. The rolling brush 20 is disposed in the accommodating chamber and located at the front of the accommodating chamber. The housing 10 may include a floor brush base 11 and a floor brush cover 12, and the floor brush cover 12 is disposed on the floor brush base 11 to form the accommodating chamber together with other components. The floor brush base 11 and the floor brush cover 12 can be detachably connected, such as a snap connection or a screw connection, so that the floor brush base 11 and the floor brush cover 12 can be conveniently detached, and parts in the accommodating cavity can be conveniently maintained.

The rolling brush 20 may be connected to the housing 10 through a rotating shaft, and may be provided with a rotating power by a power device such as a motor, so that the rolling brush 20 may be rotatably installed in the accommodating cavity, but of course, the power device may also be disposed in the accommodating cavity.

The roll brush cover 40 is positioned above the roll brush 20. The rolling brush cover 40 may be in an arc shape to cover the upper side of the rolling brush 20, the rolling brush cover 40 may be detachably connected to the housing 10, and the rolling brush 20 may be detachably connected to the housing 10. Preferably, the rolling brush cover 40 and the housing 10 can be connected by a snap-fit connection, so that the rolling brush cover 40 can be quickly detached from the housing 10, and then the rolling brush 20 can be removed to clean the rolling brush 20.

In addition, the drum brush cover 40 is preferably a transparent cover so that a user can observe the operation state of the drum brush 20 when the washing machine is operated, to find out in time when the drum brush 20 malfunctions.

The cleaning machine that this embodiment provided, through opening the wind hole on the round brush lid at the scrubbing brush, the ventilation hole makes outside air can contact with the round brush, from this, can make the round brush can fast drying through ventilation channel to be favorable to the flavor that looses of round brush, prevent that the round brush from going mildy.

Further, the inside of the floor brush also comprises a partition and a sewage suction channel 30, and the partition separates the ventilation hole 41 from the sewage suction channel 30. The dirt suction channel 30 is used to suck dirt from the surface to be cleaned. Specifically, the dirt suction passage 30 has a suction opening to which dirt is agitated by the roll brush 20 to suck the dirt away. Wherein the surface to be cleaned may refer to the surface currently being cleaned by the cleaning machine, such as the floor. The dirt pick-up channel 30 may be formed by a tube, wherein the tube may be a flexible tube that is collapsible. One end of the dirt pick-up channel 30 may be used to face the surface to be cleaned, the other end of the dirt pick-up channel 30 may be connected to a recycling bin, and a negative pressure source, such as an airflow generator, may be provided on the dirt pick-up channel 30 for providing a negative pressure. The air flow generator generates a large suction force to suck the dirt on the surface to be cleaned into the recycling bin at the other end through one end of the dirt sucking channel 30. The dirt on the surface to be cleaned may be liquid dirt, such as sewage, or solid dirt, and this embodiment is not limited. And the vent hole 41 is isolated from the sewage suction channel 30 by the isolating piece, so that the vent hole 41 can not influence the negative pressure suction of the sewage suction channel 30, and the negative pressure suction of the sewage suction is not influenced when the outside air can be in contact with the rolling brush.

Further, the spacer may extend to both ends of the roll brush 20 in a direction parallel to the axial direction of the roll brush 20. So that the partition member can completely isolate the ventilating hole 41 from the soil sucking passage 30 to the maximum in the length direction of the roll brush.

As shown in fig. 1, the front side bottom of the roll brush cover 40 may have an opening 42, the vent hole 41 may communicate with the opening 42 to form a vent passage 50 (a path shown by a dotted arrow in fig. 2), the vent passage 50 is located in front of the roll brush 20, the soil pick-up passage 30 is located behind the roll brush 20, and the vent passage 50 and the soil pick-up passage 30 are isolated from each other by a partition so that the vent passage 50 does not communicate with the soil pick-up passage 30.

Preferably, the position of the ventilation hole 41 includes at least the top of the rolling brush cover 40, so that the ventilation hole 41 on the top of the rolling brush cover 40 and the opening 42 on the bottom of the front side of the rolling brush cover 40 can form a ventilation path as long as possible, which is more advantageous for ventilation drying of the rolling brush 20.

The ventilation holes 41 at the top of the drum brush cover 40 may include a plurality of ventilation holes 41 arranged in a line in parallel to the axial direction of the drum brush 20. The shape and size of each vent hole 41 may be the same or different, and this embodiment is not limited. The distance from each ventilation hole 41 to the opening 42 of the front side bottom of the drum brush cover 40 may be equal, and the shape and size of each ventilation hole 41 may be the same, whereby it is possible to ensure as much as possible that the degree of ventilation drying in the longitudinal direction of the drum brush 20 is substantially the same, it being understood that the axial direction of the drum brush 20 is parallel to the longitudinal direction.

Of course, in other embodiments, one or more vents may be formed at other positions of the brush roll cover 40. It can be understood that the size of the vent hole 41 formed in the rolling brush cover 40 is not too large, and if the size of the vent hole 41 formed in the rolling brush cover 40 is too large, residual dirt splashed by the rolling brush 20 may be splashed out through the vent hole 41 formed in the rolling brush cover 40 when the rolling brush is rotated, thereby reducing the user experience.

On the other hand, since the vent hole 41 is formed at the top of the brush cover 40, the residual dirt splashed by the rotation of the brush 20 must overcome its own weight to be splashed out of the vent hole 41 at the top of the brush cover 40, and therefore, the vent hole 41 is formed at the top of the brush cover 40 to extend the vent path, thereby ensuring the ventilation effect and effectively preventing the dirt of the brush 20 from being splashed out.

Therefore, in specifically designing the size and position of the vent hole 41, the design can be made in consideration of the above factors.

As shown in fig. 2, a liquid spraying device 60 may be further provided in the housing 10 and behind the roller brush 20, and the liquid spraying device 60 may spray liquid toward the roller brush 20. Specifically, the liquid spraying device 60 may be communicated with a liquid storage device (not shown in the figure) through a pipeline, a cleaning solution may be contained in the liquid storage device, the cleaning solution includes clear water, a cleaning agent or a mixture of the cleaning agent and the clear water, and when the rolling brush 20 rotates, the liquid spraying device 60 sprays the cleaning solution to the rolling brush 20 to wet the rolling brush 20, so that the rolling brush 20 wipes stubborn stains on the surface to be cleaned.

It should be noted that the vent 41 is disposed on the roller cover 40, the liquid spraying device 60 is disposed in the housing 10 of the floor brush, and the liquid spraying device 60 may be located behind the roller cover 40.

FIG. 3 is an enlarged view taken at A in FIG. 2; as shown in fig. 2 and 3, the liquid spraying device 60 is located above the dirt suction passage 30, and a first scraping member 70 is provided between the liquid spraying device 60 and the dirt suction passage 30, and the first scraping member 70 is in abutting contact with the surface of the roller brush 20. In practical application, the abutting acting force between the first scraping part 70 and the rolling brush 20 can be reasonably designed, so that when the rolling brush 20 rotates, the first scraping part 70 can continuously scrape off the sewage on the rolling brush 20, meanwhile, the normal rotation of the rolling brush 20 is not influenced, the sewage scraped by the first scraping part 70 falls on the surface to be cleaned, and meanwhile, the sewage is sucked away into the recovery barrel through the sewage sucking channel 30.

Fig. 4 is an enlarged view of fig. 2 at B. As shown in fig. 2 and 4, a second scraping member 80 may be further provided above the liquid spraying device 60, and the second scraping member 80 is in abutting contact with the surface of the roller brush 20. Wherein the force applied by the second scraper 80 to the surface of the roller brush 20 may be smaller than the force applied by the first scraper 70 to the surface of the roller brush 20. In general, the liquid sprayed from the liquid spraying device 60 onto the roller brush 20 is not uniform enough, and the second scraping element 80 applies a small abutting force to the roller brush 20, so that the second scraping element 80 can scrape the cleaning liquid on the roller brush 20 uniformly, and the roller brush 20 can be wetted uniformly as much as possible.

It should be noted that, in the present embodiment, the extending depth of the first scraping element 70 on the rolling brush 20 may be deeper than the extending depth of the second scraping element 80 on the rolling brush 20, so that the abutting force of the second scraping element 80 against the rolling brush 20 is smaller than the abutting force of the first scraping element 70 against the rolling brush 20. So that the roll brush 20 can scrape off as much contaminated water as possible from the roll brush 20 by the first scraping members 70 and the cleaning liquid from the roll brush 20 is uniformly scraped by the second scraping members 80.

Preferably, in the working state, the roller brush rotates counterclockwise (as shown in fig. 2), and the roller brush passes through the first scraping member 70, the liquid spraying area and the second scraping member 80 in sequence, so that the dirt on the roller brush is scraped off before the cleaning liquid is sprayed, and the dirt is prevented from being mixed in the cleaning liquid.

As a more preferable embodiment, the abutting force between the first scraper 70 and/or the second scraper 80 and the rolling brush 20 is adjustable, and specifically, the abutting force can be adjusted by adjusting the installation position of the first scraper 70 and/or the second scraper 80, for example, taking the first scraper 70 as an example, the first scraper 70 can be connected with the housing 10 through a fastener, a plurality of through holes for the fastener to pass through are opened on the first scraper 70, and the fastener can make the first scraper 70 closer to or farther from the rolling brush 20 through different through holes, so that the abutting force between the first scraper 70 and the rolling brush 20 is adjustable. Of course, there are many ways to realize the adjustable abutting force between the first scraping element 70 and/or the second scraping element 80 and the rolling brush 20, and those skilled in the art can design the abutting force specifically, which is not an example. Further, the first scraper 70 and/or the second scraper 80 extend from one end of the roll brush 20 to the other end of the roll brush 20 in a direction parallel to the axis of the roll brush 20. The first scraping part 70 extends from one end of the rolling brush 20 to the other end of the rolling brush 20 along a direction parallel to the axis of the rolling brush 20, and during the rotation of the rolling brush 20, each position of the outer side surface of the rolling brush 20 can be in abutting contact with the first scraping part 70, and the first scraping part 70 can scrape off the sewage at each position on the rolling brush 20. The second scraping member 80 extends from one end of the rolling brush 20 to the other end of the rolling brush 20 along the direction parallel to the axis of the rolling brush 20, and during the rotation of the rolling brush 20, each position of the outer side surface of the rolling brush 20 can be in abutting contact with the second scraping member 80, so that the wetting degree of all positions of the rolling brush 20 can be ensured to be basically the same.

On the other hand, at least one of the first and second scrapers 70 and 80 can extend in the length direction of the roll brush 20, and thus, the ventilation channel 50 can be isolated from the soil pick-up channel 30 by the first and/or second scrapers 70 and 80 so that the ventilation channel 50 is not communicated with the soil pick-up channel 30. That is, the first scraper 70 and/or the second scraper 80 form a partition to separate the ventilation hole 41 from the dirt suction channel 30, and further, the ventilation channel 50 is separated from the dirt suction channel 30, so that the opening of the ventilation hole 41 does not affect the negative pressure of the suction port. In addition, it should be noted that the structure design for making the ventilation channel 50 not communicated with the dirt suction channel 30 may be other, for example, a baffle plate for isolating the ventilation channel 50 from the dirt suction channel 30 is arranged in the housing 10, the baffle plate can be infinitely close to but not in contact with the outer side surface of the rolling brush 20, and the ventilation channel 50 can also be not communicated with the dirt suction channel 30. Of course, the present invention is not limited thereto.

On the basis of the above embodiment, further, in the height direction of the floor brush, the first scraping member 70 and the second scraping member 80 are both located between the vent hole 41 and the dirt suction channel 30. Thus, the ventilation channel 50 and the soil pick-up channel 30 can be disconnected by the double securing of the first scraper 70 and the second scraper 80.

The first scraper 70 and/or the second scraper 80 extend in the radial direction of the roller brush 20 to abut against the surface of the roller brush 20. By doing so, the wiper is brought into positive contact with the roll brush 20, and the force of the wiper can be better applied to the roll brush 20.

Preferably, as shown in fig. 3, the first scraper 70 may have a plate shape; the edge of one side of the contact end of the first scraping element 70 and the surface of the roller brush 20, which is far away from the liquid spraying device 60, is in round transition; alternatively, the edges of the two sides of the contact end of the first scraping element 70 and the surface of the roller brush 20 are rounded. Thus, during the rotation (clockwise rotation during forward movement) of the roller brush 20, the corners of the first scraping element 70 do not generate sharp scratches on the roller brush 20, and the first scraping element 70 does not scratch the roller brush 20 while ensuring to scrape off the contaminated water on the roller brush 20.

Similarly, the second scraper 80 may have a plate shape; the contact end of the second scraping piece 80 and the surface of the roller brush 20 is in round-angle transition with one side edge close to the liquid spraying device 60; alternatively, the edges of the two sides of the contact end of the second scraping element 80 and the surface of the roller brush 20 are rounded. The effects are the same as those of the first scraper 70, and will not be described again.

As shown in fig. 1, in some embodiments, the floor brush may further include: the front cushion 90. The front bumper 90 is provided on the front-side outer surface of the roll brush cover 40. The front cushion member 90 may be a rubber member that may extend in a strip shape entirely in the longitudinal direction of the roll brush cover 40, or may be dispersedly arranged in a block shape in the longitudinal direction of the roll brush cover 40. Through setting up preceding bolster 90 can effectively cushion the scrubbing brush in the in-process of forward motion, the impact of striking the place ahead barrier.

Further, the floor brush may further include: and a side cushion 100 provided on an outer surface of a side portion of the floor brush. The side cushion 100 may also be a rubber member, similar to the front cushion 90, and the side cushion 100 may extend in a strip shape throughout the width direction of the floor brush, or may be dispersed in a block shape in the width direction of the floor brush. The impact force from an obstacle on the side can be effectively buffered by providing the side cushion 100.

As shown in fig. 1, the roll brush cover 40 may include a front cover 40a and side covers 40b connected to both ends of the front cover 40 a; the side cushion 100 may be provided on an outer surface of the side cover 40 b. Alternatively, in other embodiments, the side bumper 100 is provided on the outer side surface of the case 10.

When the side cushion 100 is provided on the outer surface of the side cover 40b, the front cushion 90 is integrally molded with the side cushion 100. The front bumper 90 and the side bumper 100 may be integrally formed, as shown in fig. 1, the whole rubber strip extends from the left side cover of the rolling brush cover 40 to the front cover 40a and to the right side cover, so as to protect the floor brush from the front and the side, thereby achieving a better anti-collision effect, and having a simple structure and a low cost.

the method comprises the following steps: a housing 10, a roll brush 20, and a roll brush cover 40. The drum brush cover 40 is provided above the drum brush 20, and a ventilation hole 41 is provided on the drum brush cover 40, the ventilation hole 41 allowing external air to contact the drum brush 20.

Specifically, the roll brush 20 is coupled in the housing 10. The housing 10 and the brush cover 40 may enclose a receiving chamber, and a plurality of floor brush related parts may be disposed in the receiving chamber of the housing 10. The rolling brush 20 is disposed in the receiving cavity and located at the front of the receiving cavity. The housing 10 may include a floor brush base 11 and a floor brush cover 12, and the floor brush cover 12 is disposed on the floor brush base 11 to form the accommodating chamber together with other components. The floor brush base 11 and the floor brush cover 12 can be detachably connected, such as a snap connection or a screw connection, so that the floor brush base 11 and the floor brush cover 12 can be conveniently detached, and parts in the accommodating cavity can be conveniently maintained.

The scrubbing brush that this embodiment provided, through opening the wind hole on the round brush lid, the ventilation hole makes outside air can contact with the round brush, from this, can make the round brush can rapid draing through ventilation channel to be favorable to the flavor that looses of round brush, prevent that the round brush from going mildy.

Further, the inside of the floor brush also comprises a partition and a sewage suction channel 30, and the partition separates the ventilation hole 41 from the sewage suction channel 30. The dirt suction channel 30 is used to suck dirt from the surface to be cleaned. Specifically, the dirt suction passage 30 has a suction opening to which dirt is agitated by the roll brush so as to suck away the dirt. Wherein the surface to be cleaned may refer to the surface currently being cleaned by the cleaning machine, such as the floor. The soil pick-up channel 30 may be formed of a pipe. One end of the soil suction channel 30 may be used to face a surface to be cleaned, the other end of the soil suction channel 30 may be connected to a recycling bin, and a negative pressure source, such as an air pump, for providing a negative pressure may be further provided on the soil suction channel 30. The air pump generates a large suction force to suck the dirt on the surface to be cleaned into the recycling bin at the other end through one end of the dirt sucking channel 30. The dirt on the surface to be cleaned may be liquid dirt, such as sewage, or solid dirt, and this embodiment is not limited. And the partition piece separates the vent hole 41 from the sewage suction channel 30, so that the vent hole 41 does not influence the negative pressure suction of the sewage suction channel 30, and when the outside air can contact with the rolling brush, the negative pressure suction of the sewage suction is not influenced.

As shown in fig. 1, the front side bottom of the roll brush cover 40 has an opening 42, the vent hole 41 may communicate with the opening 42 to form a vent passage 50 (a path shown by a dotted arrow in fig. 2), the vent passage 50 is located in front of the roll brush 20, the dirt suction passage 30 is located behind the roll brush 20, and the vent passage 50 and the dirt suction passage 30 are isolated from each other by a partition, so that the vent passage 50 does not communicate with the dirt suction passage 30.

Of course, in other embodiments, one or more vents may be formed at other positions of the brush roll cover 40. It can be understood that the size of the vent hole 41 formed in the rolling brush cover 40 is not large enough, and if the size of the vent hole 41 formed in the rolling brush cover 40 is large enough, residual dirt splashed by the rolling brush 20 may be splashed out through the vent hole 41 formed in the rolling brush cover 40 during rotation, thereby reducing the user experience.

Fig. 4 is an enlarged view of fig. 2 at B. As shown in fig. 2 and 4, a second scraping member 80 may be further provided above the liquid spraying device 60, and the second scraping member 80 is in abutting contact with the surface of the roller brush 20. Wherein the force applied by the second scraper 80 to the surface of the drum brush 20 may be smaller than the force applied by the first scraper 70 to the surface of the drum brush 20. In general, the liquid sprayed from the liquid spraying device 60 onto the roller brush 20 is not uniform enough, and the second scraping element 80 applies a small abutting force to the roller brush 20, so that the second scraping element 80 can scrape the cleaning liquid on the roller brush 20 uniformly, and the roller brush 20 can be wetted uniformly as much as possible.

It should be noted that other structures and functions of the floor brush in the cleaning machine in this embodiment are the same as those in the first embodiment, and specific reference may be made to the description of the first embodiment, which is not repeated herein.

The floor brush and the cleaning machine provided by the embodiment of the invention are described in the following by combining specific application scenes:

application scenario 1:

the user uses the cleaning machine to wash ground, and after accomplishing work, the user can place the scrubbing brush of cleaning machine on subaerial, perhaps places on the tray, forms the natural draft passageway between the bottom opening of the ventilation hole that the round brush of scrubbing brush was covered and scrubbing brush for outside air can contact with the round brush, weathers the round brush naturally, and, is favorable to the flavor that looses of round brush, prevents that the round brush from going mildy.

Application scenario 2:

when a user uses the cleaning machine to clean the ground, the floor brush of the cleaning machine moves forwards, the rolling brush stirs and cleans the ground, the dirt suction channel continuously sucks away dirt on the ground, and due to the design that the vent hole is isolated from the dirt suction channel, the negative pressure of the suction port cannot be influenced by the arrangement of the vent hole, and the normal performance of the floor brush cannot be influenced.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
