Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Terms such as "upper," "above," "lower," "below," "first end," "second end," "one end," "another end," and the like, used herein to denote relative spatial positions, are used for ease of description to describe one element or feature's relationship to another element or feature as illustrated in the figures. The spatially relative positional terms may be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "below" can encompass both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

Furthermore, the terms "mounted", "disposed", "provided", "connected", "slidably connected", "fixed" and "sleeved" are to be understood in a broad sense. For example, "connected" may be a fixed connection, a detachable connection, or a unitary construction; can be a mechanical connection, or an electrical connection; may be directly connected, or indirectly connected through intervening media, or may be in internal communication between two devices, elements or components. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.

In the prior art, only one rotatable rolling brush is usually arranged in a rolling brush assembly of a floor brush mechanism, the rolling brush is usually a bristle rolling brush (i.e. hard brush wires are implanted into the outer surface of the rolling brush by using a bristle planting process), and the hard brush wires on the rolling brush can roll up attachments in cleaning areas such as the ground by the rotation of the rolling brush, so that the cleaning effect is improved. The bristle roll brush has a good cleaning effect on dry garbage, such as hair, dust, stained paper, cigarette butts and the like, but the adhesion force of the dry garbage and the wet garbage on the ground is different, so the cleaning effect of the bristle roll brush on wet garbage, such as coffee grounds, meals, tomato ketchup and the like is not ideal, and when the bristle roll brush is used for cleaning the wet garbage, the wet garbage often adheres to the hard brush wires of the roll brush, and along with the movement of the roll brush, the wet garbage adhered to the hard brush wires can pollute the ground and cause secondary pollution. In order to solve the problem of cleaning wet garbage, part of products improve a hard-hair rolling brush into a soft-hair rolling brush (namely, fluff materials such as felt cloth are adhered to the outer surface of the rolling brush by using a hair adhering process), but the soft-hair rolling brush is not ideal in cleaning effect on dry garbage, in actual life, dry garbage and wet garbage often exist in an area to be cleaned simultaneously, the dry garbage and the wet garbage are cleaned simultaneously by means of one rolling brush, and the actual cleaning effect is not obvious. Therefore, how to improve the ground brush mechanism to simultaneously clean the dry garbage and the wet garbage becomes a problem to be solved in the field.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. It should be apparent that the embodiments described in this application are only some embodiments of the present application, and not all embodiments of the present application. All other embodiments, which can be obtained by a person skilled in the art without making any inventive step based on the embodiments in the present application, are within the scope of protection of the present application.

In an realizable embodiment, the floor brush mechanism is provided with a partition 12, the first roller brush 21 and the second roller brush 22 being located on either side of the partition 12. The partition 12 may partition the different types of rolling brushes so that the different types of rolling brushes do not interfere with each other when rotating. Optionally, the shape of the partition 12 may match the outer contour of the rolling brush to form an airflow channel, and when the rolling brush rotates, the airflow channel may better guide the attachments rolled up by the rolling brush into the floor brush mechanism.

In an realizable embodiment, the partition 12 divides the floor brush mechanism into a first rolling brush cavity 111 and a second rolling brush cavity 112 which are isolated from each other, the first rolling brush 21 is disposed in the first rolling brush cavity 111, the second rolling brush 22 is disposed in the second rolling brush cavity 112, the second rolling brush cavity 112 is further provided with a water spraying device 1121, and the water spraying device 1121 is used for spraying water to the second rolling brush 22. Specifically, as shown in fig. 1, the partition 12 may extend in the rolling brush cavity to partition the rolling brush cavity into a first rolling brush cavity 111 and a second rolling brush cavity 112 which are isolated from each other, the first rolling brush cavity 111 and the second rolling brush cavity 112 have openings, the first rolling brush 21 is at least partially located in the first rolling brush cavity 111 and cleans the attachments on the ground through the opening of the first rolling brush cavity 111, the second rolling brush 22 is at least partially located in the second rolling brush cavity 112 and cleans the attachments on the ground through the opening of the second rolling brush cavity 112, the water spraying device 1121 is located in the second rolling brush cavity 112, and the water spraying device 1121 may spray water to the second rolling brush 22.

It should be noted that the size of the first rolling brush cavity 111 matches the size of the first rolling brush 21, and the size of the second rolling brush cavity 112 matches the size of the second rolling brush 22, so that the first rolling brush 21 and the second rolling brush 22 can rotate in the first rolling brush cavity 111 and the second rolling brush cavity 112, respectively.

In an implementation manner, a dry garbage recycling portion 113 and a wet garbage recycling portion 114 which are isolated from each other are further disposed in the floor brush body 1, the dry garbage recycling portion 113 is communicated with the first rolling brush cavity 111, the wet garbage recycling portion 114 is communicated with the second rolling brush cavity 112, the dry garbage recycling portion 113 can be used for recycling the garbage cleaned by the first rolling brush 21, and the wet garbage recycling portion 114 can be used for recycling the garbage cleaned by the second rolling brush 22.

In practical applications, the position relationship between the dry garbage recycling portion 113 and the first rolling brush cavity 111 can be determined comprehensively according to the relative position of the first rolling brush 21 in the first rolling brush cavity 111 and the rotation direction of the first rolling brush 21 during operation, so as to ensure that after the ground attachments cleaned by the first rolling brush 21 enter the first rolling brush cavity 111, the attachments can fall back into the dry garbage recycling portion 113 under the action of gravity. Optionally, an air exhaust duct may be further disposed in the floor brush mechanism, and one end of the air exhaust duct is communicated with a negative pressure source, which may be an air pump or a fan. The dry garbage recycling portion 113 is communicated with the other end of the air exhaust duct, and air in the dry garbage recycling portion 113 and the first rolling brush cavity 111 is exhausted through the air exhaust duct to form a negative pressure space in the dry garbage recycling portion 113 and the first rolling brush cavity 111, so that ground attachments swept by the first rolling brush 21 can enter the dry garbage recycling portion 113 more quickly, and a better cleaning effect is achieved. Based on the same principle, the position relationship between the wet garbage recycling part 114 and the second rolling brush cavity 112 can be set, and will not be described herein.

Because the adhesive force between the dry garbage and the ground is usually smaller than that between the wet garbage and the ground, the dry garbage is easier to clean than the wet garbage, and optionally, the floor brush mechanism can be set to clean the dry garbage firstly and then clean the wet garbage. As shown in fig. 1, the first rolling brush 21 is located at a front side of the second rolling brush 22 in the forward direction, the barrier 12 is located between the first rolling brush 21 and the second rolling brush 22 to separate the first rolling brush 21 and the second rolling brush 22 to prevent the first rolling brush 21 and the second rolling brush 22 from interfering with each other during rotation, the first rolling brush 21 is used for recycling dry garbage, and the second rolling brush 22 is used for recycling wet garbage.

Optionally, the blocking portion 12 is close to one side of the first rolling brush 21, and may be in a circular arc shape, and is matched with the outer contour of the first rolling brush 21 to form an airflow duct, when the first rolling brush 21 rotates, the airflow duct may better guide the ground attachments to enter the first rolling brush cavity 111, so that the ground attachments may enter the dry garbage recycling portion 113 communicated with the first rolling brush cavity 111.

In an realizable embodiment, the outer surface of the first rolling brush 21 has hard brush filaments and the outer surface of the second rolling brush 22 has nap. The hard brush filaments can be polypropylene brush filaments, nylon brush filaments, PBT filaments, sisal brush filaments and the like, and the fluff material can be water-absorbing material, such as sponge, or flannelette made of sheepskin, wool, terylene, acrylon, chinlon and the like. Optionally, the hard brush wires on the outer surface of the first rolling brush 21 may adopt a detachable module structure, for example, in practical application, different hard brush wire modules may be manufactured for different materials such as solid wood floors, composite floors, marble floors, ceramic tiles, cement floors, and the like, brush wires with different hardness are mounted on the different hard brush wire modules, and the hard brush wire modules and the first rolling brush 21 have mortise and tenon structures matched with each other, when the local brush mechanism cleans the ground, an operator may select different hard brush wire modules according to the material of the ground, so as to achieve a better cleaning effect; or when the brush wires on the hard brush wire module are worn, an operator can replace the hard brush wire module with a new one to ensure that the cleaning effect of the floor brush mechanism is not reduced due to the wear of the brush wires. Correspondingly, the fine hair of second round brush 22 surface also can adopt and to dismantle modular structure to the wet rubbish of different grade type, for example liquid such as soy sauce, sewage, sticky thing such as tomato ketchup, peanut butter, solid such as rice, vegetable leaf make the cladding have the fine hair module of different materials that absorbs water, the operator can select suitable fine hair module for second round brush 22 according to subaerial actual spot, in order to reach better cleaning effect.

In one scenario, the floor brush mechanism moves in the forward direction, the first rolling brush 21 and the second rolling brush 22 rotate simultaneously, the hard brush wires on the first rolling brush 21 can roll up dry garbage such as paper scraps, hair, dust, small stones and the like on the ground and part of solid wet garbage such as rice grains, vegetable leaves and the like, the garbage can be guided into the first rolling brush cavity 111 by the airflow generated by the rotation of the first rolling brush 21, and at this time, the dry garbage and the solid wet garbage are swept into the first rolling brush cavity 111 by the first rolling brush 21. As the floor brush mechanism continues to move forward, the second rolling brush 22 can perform a second cleaning on the cleaned area of the first rolling brush 21, the fluff covered on the outer surface of the second rolling brush 22 can adsorb wet garbage, such as tomato sauce, soy sauce, fruit juice and the like, which is not cleaned by the first rolling brush 21, so that the purpose of simultaneously cleaning dry garbage and wet garbage on the ground is achieved, and because the second rolling brush 22 is arranged at the rear side of the first rolling brush 21, even if the wet garbage attached to the hard brush threads on the outer surface of the first rolling brush 21 dirties the ground, the second rolling brush 22 can also clean the dirtied ground, and the secondary pollution phenomenon can be avoided.

It should be noted that, in an ideal case, the first rolling brush 21 cleans all dry garbage, and the second rolling brush 22 cleans all wet garbage. However, in practical cases, after the first rolling brush 21 is cleaned, most of the dry garbage is cleaned, but some of the dry garbage is not cleaned and remains in the area to be cleaned, and the second rolling brush 22 can clean the wet garbage and the remaining dry garbage.

In an implementation, a water spraying device 1121 may be further disposed in the second rolling brush cavity 112, and the water spraying device 1121 is used for spraying water to the second rolling brush 22. Alternatively, the water spraying device 1121 may be configured such that when the second rolling brush 22 starts to rotate, the water spraying device 1121 starts spraying water to the second rolling brush 22, or a switch may be provided on the floor brush mechanism, so that an operator selects when to spray water to the second rolling brush 22. Alternatively, after the water spraying device 1121 starts spraying water to the second rolling brush 22, the water spraying device 1121 may be set to continuously spray water to the second rolling brush 22, or may be set to intermittently spray water to the second rolling brush 22 according to a preset time. The water sprayed from the water spray device 1121 can achieve a cleaning and moistening effect on the second rolling brush 22.

Optionally, the water spraying device 1121 may have a plurality of spray heads, the plurality of spray heads may be arranged side by side or staggered, and the arrangement length of the spray heads on the water spraying device 1121 may refer to the axial length of the second rolling brush 22, so as to ensure that the second rolling brush 22 can obtain moisture in the axial direction.

It should be noted that the water spraying device 1121 may be disposed at any position in the second rolling brush cavity 112, and only the water spraying device 1121 is required to spray water to the second rolling brush 22.

When the second rolling brush 22 rotates, the fluff covered on the outer surface can absorb liquid dirt such as sewage, soy sauce, tomato sauce and the like on the ground, and when a large amount of dirt is absorbed by the water absorption fluff on the outer surface of the second rolling brush 22, the cleaning effect of the wet garbage on the area to be cleaned is reduced. Therefore, in an realizable embodiment, a scraper 1122 may be provided in the second roll brush chamber 112, and an end of the scraper 1122 is in contact with an outer edge of the second roll brush 22, so that when the second roll brush 22 rotates, the scraper 1122 guides the dirt in the second roll brush 22 to the wet waste recycling part 114. Referring to fig. 2 and 3, the end of the scraping plate 1122 contacts the outer edge of the second roller brush 22 and applies a certain force to the second roller brush 22, so that the scraping plate 1122 can press down the nap on the outer surface of the second roller brush 22 when the second roller brush 22 rotates, thereby squeezing out the moisture absorbed in the nap, and at the same time, the scraping plate 1122 can scrape off the rice grains, vegetable leaves, candy, etc. adhered to the nap. The wet trash collecting unit 114 is located below the scraper 1122, and can receive moisture squeezed from the nap and attached matter such as rice grains and vegetable leaves scraped from the nap.

In a scenario where the pile fibers on the outer surface of the second roller brush 22 may be adsorbed with relatively hard solids such as small stones, the scraper 1122 and the small stones may together block the rotation of the second roller brush 22 when the scraper 1122 comes into contact with the small stones, in which case the second roller brush 22 may be stopped or the driving motor may be burned out due to an excessive instantaneous load. Therefore, alternatively, one end of the scraper 1122 connected to the second rolling brush cavity 112 may be provided in a floating structure, for example, the scraper 1122 is connected to the second rolling brush cavity 112 through an elastic member, so that when the resistance between the scraper 1122 and the second rolling brush 22 is excessive, the scraper 1122 can change its relative position with the second rolling brush 22, thereby allowing the second rolling brush 22 to normally rotate.

Optionally, the second rolling brush cavity 112 may be provided with a water spraying device 1121 and a scraping plate 1122 at the same time, or may be provided with the water spraying device 1121 or the scraping plate 1122 separately. When the water spray device 1121 and the scraper 1122 are simultaneously disposed in the second rolling brush cavity 112, the water spray device 1121 is located in front of the scraper 1122 along the advancing direction of the floor brush mechanism, so as to prevent the water flow sprayed from the water spray device 1121 and the water flow extruded from the scraper 1122 from interfering with each other.

In an realizable embodiment, the scraper 1122 has a body 11221 extending toward the second rolling brush 22 and a bent portion 11222, the bent portion 11222 is bent backward from the end of the body 11221 toward the advancing direction of the floor brush mechanism, the bent portion 11222 contacts the outer edge of the second rolling brush 22 and applies a certain force to the second rolling brush 22, when the second rolling brush 22 rotates, the bent portion 11222 can form a squeezing effect on the nap on the outer surface of the second rolling brush 22, so as to squeeze out the moisture in the nap, and at the same time, the bent portion 11222 can scrape off small stones, rice grains, vegetable leaves, candies and the like attached to the nap. The wet garbage collection portion 114 is located behind the bending portion 11222 along the advancing direction of the floor brush mechanism, and the wet garbage collection portion 114 is disposed corresponding to the bending portion 11222, so that the wet garbage collection portion 114 can receive moisture squeezed out of the fluff by the bending portion 11222 and attachments such as rice grains, vegetable leaves and the like scraped from the fluff.

Since the second rolling brush cavity 112 has an opening, in one scenario, moisture squeezed out of the nap by the bending portion 11222 and attachments such as rice grains, vegetable leaves and the like scraped from the nap may fall off from the opening, so that the cleaning effect of the second rolling brush 22 on the ground is not ideal.
