Description

Technical Field

[0001] The present application relates to the technical field of cleaning devices, and particularly to a cleaning equipment. Background Art

[0002] In recent years, due to the ability to replace manual labor and automatically complete various cleaning tasks, and with high cleaning efficiency and good cleaning effect, cleaning robots have been widely popularized and applied, providing great convenience for people's lives.

[0003] The main task of a cleaning robot is to clean the garbage on the ground. Its main components include double-sided brushes, a garbage shovel, a rotary brush, and a garbage box. The garbage shovel is arranged between the double-sided brushes and the rotary brush, and the garbage box is arranged behind the rotary brush. During the cleaning process, the double-sided brushes push the garbage to the rotary brush through the garbage shovel, and the rotary brush then sends the garbage into the garbage box. However, during the cleaning process, the rotating side brushes are likely to throw the garbage flying from the side of the cleaning robot, resulting in secondary pollution of the ground that has already been cleaned, affecting the cleaning performance and effect of the cleaning robot. Summary of the Invention

[0004] Based on this, it is necessary to provide a cleaning equipment for the problem that the side brushes throw the garbage flying and cause secondary pollution of the ground.

[0005] The present application provides a cleaning equipment, which includes:

[0006] A chassis;

[0007] A side brush mechanism, arranged on the chassis;

[0008] A garbage guiding bin, arranged on the chassis and behind the side brush mechanism. The end wall of the inlet end of the garbage guiding bin is designed as a profiling part, and the profiling part is in conformity with the shape of the rear side of the side brush mechanism; and,

[0009] A garbage shovel, connected to the chassis and / or the garbage guiding bin. The garbage shovel is arranged behind the side brush mechanism and below the garbage guiding bin. The garbage shovel and the garbage guiding bin enclose a garbage recycling channel. The garbage shovel is inclined in the front-back direction, and the front part of the garbage shovel is arranged in cooperation with the bristles of the side brush mechanism.

[0010] When the cleaning device of this solution is working, by controlling the rotation of the side brush mechanism and accompanying the movement of the cleaning device, the side brush mechanism can sweep up the garbage on the ground and send it into the garbage collection mechanism of the cleaning device through the garbage collection channel formed by the cooperation of the garbage shovel and the garbage guiding bin, thereby achieving the purpose of cleaning the ground. During this process, since the garbage shovel is arranged in cooperation with the bristles of the side brush mechanism, and the end wall of the inlet end of the garbage guiding bin is designed as a profiling part, the profiling part is adapted to the shape of the rear bristles of the side brush mechanism. For example, if the bristles of the side brush mechanism are flat or arc-shaped structures, the corresponding profiling part is also a flat or arc-shaped structure; in this way, the garbage gathered by the bristles of the side brush mechanism will also be blocked by the profiling part when passing through the profiling part, and thus can be prevented from being thrown out by the rotating side brush mechanism, so as to avoid secondary pollution to the ground that has been cleaned and ensure the cleaning efficiency of the cleaning device.

[0032] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present application, if there is a term "plurality", the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0033] In this application, unless otherwise clearly specified or limited, if terms such as "installed", "connected", "linked", "fixed", etc. appear, these terms shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited.

[0035] It should be noted that if an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or there can also be an intermediate element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0036] Refer to Figure 1 , a cleaning device 100 shown in an embodiment of this application, which is specifically a cleaning robot that can replace manual labor to move autonomously and automatically complete the ground cleaning operation. However, it should be noted that the machine equipment in the background technology of this application is only exemplified by a cleaning robot, but is not limited to a cleaning robot. Exemplarily, the cleaning device 100 can also be a driving-type cleaning vehicle, a push-type cleaning vehicle or other cleaning devices.

[0037] Refer to Figures 1 to 4, the cleaning device 100 includes a chassis 10, a side brush mechanism 20, a garbage guiding bin 30, and a garbage shovel 40. Among them, the side brush mechanism 20 is arranged on the chassis 10. The side brush mechanism 20 can rotate relative to the chassis 10 to gather and collect the garbage on the ground. It can be understood that the cleaning device 100 is used to clean the ground, and the side brush mechanism 20 arranged on its chassis 10 is arranged on the side of the chassis 10 close to the ground, which is the proper meaning of the side brush mechanism 20 being arranged on the chassis 10.

[0038] Please continue to refer to Figure 1 and Figure 2 , for example, in an optional embodiment, the side brush mechanism 20 includes a first side brush assembly 21 and a second side brush assembly 22. The first side brush assembly 21 and the second side brush assembly 22 are arranged side by side on the chassis 10 and arranged along the width direction of the cleaning device 100.

[0039] The first side brush assembly 21 and the second side brush assembly 22 are arranged in a symmetric structure and are both arranged at the head of the cleaning device 100. The so-called head of the cleaning device 100 refers to the front part of the cleaning device 100 when it moves. Of course, the cleaning device 100 also has a tail, which refers to the rear part of the cleaning device 100 when it moves. The traveling direction of the cleaning device 100 refers to the direction of forward movement when the head of the cleaning device 100 faces forward. With such a setting, as the cleaning device 100 moves, the first side brush assembly 21 and the second side brush assembly 22 can synchronously sweep and gather the garbage on the ground, that is, form the effect of cleaning the ground while moving.

[0040] It can be understood that both the first side brush assembly 21 and the second side brush assembly 22 include a motor and a side brush. The chassis 10 includes a bottom plate 11. The motor is installed on the bottom surface of the bottom plate 11, and the installation method can be at least one of screwing, clamping, bonding, etc. The side brush is drivingly connected to the motor, and the motor drives the side brush to rotate, and the bristles of the side brush rotate and rub against the ground. Observed from the top view angle of the cleaning device 100, the rotation direction of the side brush of the first side brush assembly 21 is opposite to the rotation direction of the side brush of the second side brush assembly 22, and both rotate towards the inner side relative to each other. According to needs, the side brush is of a disc-shaped structure, which includes bristles distributed in a cluster-like and radioactive manner; the end surface where the side brush bristles are located can be parallel to the ground or arranged at a preset angle inclined to the ground. Preferably, in the embodiment of the present application, the side brush mechanism 20 is inclined backward, and at least part of the bristles of the side brush mechanism 20 are attached to the front part of the garbage shovel 40. The side brush is arranged in an inclined posture and is attached to the front end of the garbage shovel 40, so that the garbage on the ground can be better guided by the garbage shovel 40 to other cooperating mechanisms inside the cleaning device 100 for collection, strengthening the cleaning effect of the side brush.

[0041] Please continue to refer to Figure 3, the garbage guiding bin 30 is arranged on the chassis 10 and is disposed at the rear side of the side brush mechanism 20 along the traveling direction of the cleaning device 100. The end wall of the inlet end 31 of the garbage guiding bin 30 is provided with a profiling portion 311, and the profiling portion 311 is in conformity with the shape of the rear side of the side brush mechanism 20. The garbage shovel 40 is connected to the chassis 10 and / or the garbage guiding bin 30. The garbage shovel 40 is arranged at the rear side of the side brush mechanism 20 and is disposed below the garbage guiding bin 30. The garbage shovel 40 and the garbage guiding bin 30 enclose a garbage collection channel. The garbage shovel 40 is inclined in the front-rear direction, and the front portion of the garbage shovel 40 is arranged in cooperation with the bristles of the side brush mechanism 20. It should be noted that the cooperation between the garbage shovel 40 and the bristles of the side brush mechanism 20 may refer to a clearance fit or a contact fit between the garbage shovel 40 and the bristles of the side brush mechanism 20, and can be flexibly selected according to actual needs.

[0042] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: When the cleaning device 100 of this solution works, by controlling the rotation of the side brush mechanism 20 and accompanying the movement of the cleaning device 100, the side brush mechanism 20 can sweep up the garbage on the ground and send it into the garbage collection mechanism of the cleaning device 100 through the garbage collection channel formed by the enclosure of the garbage shovel 40 and the garbage guiding bin 30, thereby achieving the purpose of cleaning the ground. During this process, since the garbage shovel 40 is arranged in cooperation with the bristles of the side brush mechanism 20, and the end wall of the inlet end 31 of the garbage guiding bin 30 is designed as a profiling portion 311, the profiling portion 311 is in conformity with the shape of the rear bristles of the side brush mechanism 20. For example, if the bristles of the side brush mechanism 20 are in a planar or arc-shaped structure, the corresponding profiling portion 311 is also in a planar or arc-shaped structure. In this way, the garbage gathered by the bristles of the side brush mechanism 20 will also be blocked by the profiling portion 311 when passing through the profiling portion 311, and thus can be prevented from being thrown out by the rotating side brush mechanism 20, thereby avoiding secondary pollution to the ground that has been cleaned and ensuring the cleaning efficiency of the cleaning device 100.

[0043] Please continue to refer to Figures 1 to 3 , in addition, on the basis of any of the above embodiments, the cleaning device 100 further includes a rotary brush 50 and a garbage box 60. The chassis 10 includes a first upright post 12 and a second upright post 13 that are spaced relatively opposite along the width direction of the cleaning device 100. Specifically, the first upright post 12 and the second upright post 13 are installed on the bottom surface of the bottom plate 11, and the installation method can be at least one of screw connection, welding, snap connection, magnetic attraction connection, etc., and can be flexibly selected according to actual needs. In the embodiment of the drawings, the garbage shovel 40 and the chassis 10 are installed and fixed below the garbage guiding bin 30 through the first upright post 12 and the second upright post 13.

[0044] One axial end of the roller brush 50 is rotatably disposed on the first column 12, and the other axial end of the roller brush 50 is rotatably disposed on the second column 13. The roller brush 50 is disposed at the rear side of the garbage shovel 40, and the roller brush 50 is disposed below the rear side of the garbage guide bin 30; and the garbage box 60 is disposed at the rear side of the roller brush 50. It can be understood that the roller brush 50 is connected to a motor, and the motor drives the roller brush 50 to rotate, so that the garbage guided by the garbage shovel 40 and the garbage guide bin 30 is thrown to the garbage box 60 disposed at the rear side of the roller brush 50.

[0045] Furthermore, if Figure 2 and Figure 3 As shown, the rear sides of the first column 12 and the second column 13 are also spaced apart and opposite to each other with engaging columns 15, and the bottom wall of the front part of the garbage box 60 is provided with an engaging groove 61 matching with the engaging column 15, and the garbage box 60 is arranged on the rear side of the roller brush 50 through the engaging limit of the engaging column 15 and the engaging groove 61.

[0046] Furthermore, the inner top wall 34 of the garbage guide bin 30 is inclined in the front-to-back direction, and the end of the inner top wall 34 of the garbage guide bin 30 close to the side brush mechanism 20 is lower than the end of the inner top wall 34 of the garbage guide bin 30 close to the garbage box 60. In other words, the garbage channel includes an inlet end 31 and an outlet end 33, and the distance between the inner top wall 34 of the garbage guide bin 30 and the ground gradually increases from the inlet end 31 to the outlet end 33.

[0047] Compared with a horizontal top wall, the above scheme sets the inner top wall 34 of the garbage guide bin 30 as a slope that is low in the front and high in the back. When the roller brush 50 rotates to lift the garbage and hit the slope, the incident angle of the garbage hitting the top wall is increased. Therefore, the garbage can be thrown into the area closer to the rear of the garbage box 60 after rebounding, thereby avoiding the problem of garbage accumulation in the front of the garbage box 60 due to a small rebound angle.

[0048] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the garbage shovel 40 further includes a roller brush front stop 42, which is disposed on the side of the rear portion of the garbage shovel 40 close to the ground, and the roller brush front stop 42 surrounds the outer circumferential front portion of the roller brush 50. The roller brush front stop 42 can prevent the roller brush 50 from sweeping garbage into the gap between the rear end of the garbage shovel 40 and the ground when rotating, thereby causing a problem of low cleaning efficiency.

[0049] Please continue reading Figure 2 and Figure 3, the dust box 60 further includes a rear roller guard 62 disposed on the front side of the dust box 60 near the ground, and the rear roller guard 62 surrounds the rear outer periphery of the roller brush 50. The provision of the rear roller guard 62 can prevent the roller brush 50 from sweeping the garbage into the gap between the dust box 60 and the ground when rotating.

[0050] Please continue to refer to Figure 2 and Figure 4 , on the basis of the above embodiment, further, grooves 41 are recessed on both opposite sides of the dustpan 40 along the width direction of the cleaning device 100. The openings of the grooves 41 are arranged facing the garbage guiding bin 30. Protrusions 32 are provided on both opposite sides of the garbage guiding bin 30 along the width direction of the cleaning device 100. The width of the protrusion 32 is smaller than the width of the groove 41, and at least part of the protrusion 32 extends into the groove 41. The protrusions 32 and the grooves 41 are arranged in one-to-one correspondence and cooperate to form a blocking structure. The blocking structure can be in contact with or in clearance fit with the bristles of the side brush mechanism 20.

[0051] For example, in the present application, the length of the bristles of the side brush mechanism 20 is designed to be able to reach the blocking structure. Therefore, when the side brush mechanism 20 rotates, its bristles will impact and scrape the blocking structure, so that the garbage on the front end of the bristles will vibrate and fall off from the bristles due to the blocking impact force of the blocking structure, thereby realizing the self-cleaning of the bristles of the side brush mechanism 20. On the one hand, it can ensure that the garbage is more completely swept into the cleaning device 100, improving the cleaning effect; on the other hand, it can also prevent the garbage from being thrown out from the side of the cleaning device 100 by the rotational centrifugal force of the bristles of the side brush mechanism 20, thereby avoiding secondary pollution to the ground that has been cleaned.

[0052] Please continue to refer to Figure 4 , further, the two protrusions 32 are arranged in a V-shaped structure. The first distance between the ends of the two protrusions 32 close to the side brush mechanism 20 is smaller than the second distance between the ends of the two protrusions 32 far from the side brush mechanism 20. The opposite side walls of the groove 41 are parallel. The protrusion 32 and the side wall of the groove 41 are arranged at an angle and are in contact with each other. After such an arrangement, the blocking and hitting effects of the two protrusions 32 on the front ends of the bristles of the side brush mechanism 20 are better, and at the same time, it can prevent the garbage from leaking out from the fitting gap between the groove 41 and the protrusion 32 and falling onto the ground outside the side of the cleaning device 100, eliminating the potential hidden danger of secondary pollution to the ground; in addition, the protrusion 32 and the side wall of the groove 41 are arranged at an angle and form a contact relationship, which can also play a positioning role in the assembly of the dustpan 40 and the garbage guiding bin 30, improving the structural stability after the two are assembled. Specifically, the first distance is Figure 4 D1 in Figure 4 and the second distance is

[0053] When the cleaning device 100 is working, the garbage on the ground is swept up by the side brush mechanism 20 and pushed onto the garbage shovel 40. Then, the garbage shovel 40 pushes the garbage to the rotary brush 50. The rotary brush 50 rotates to throw up the garbage. Some of the garbage can be directly thrown into the garbage bin 60, and some of the garbage is thrown towards the garbage guiding bin 30 and bounces into the garbage bin 60 after being impacted by the garbage guiding bin 30, realizing that the garbage is collected and temporarily stored in the garbage bin 60. When the cleaning operation is over and the cleaning device 100 stops, the collected garbage can be dumped and removed by removing the garbage bin 60, so that the cleaning device 100 has the ability to perform secondary cleaning operations.

[0054] Preferably, in an alternative embodiment, there is an overlapping part between the bristles of the side brush mechanism 20 and the bristles of the rotary brush 50, that is, the length of the bristles of the side brush mechanism 20 is designed to be able to reach the bristles of the rotary brush 50. In this way, on the one hand, as the side brush mechanism 20 and the rotary brush 50 rotate simultaneously, the overlapping part formed by the bristles of the side brush mechanism 20 and the bristles of the rotary brush 50 will cause mutual scraping, so as to remove as much as possible the garbage contaminated at the front end of the bristles of the side brush mechanism 20, reducing the probability of the garbage being thrown out of the cleaning device 100 to the outside and reducing the secondary pollution of the ground; on the other hand, it can also prevent some heavier garbage from falling through the gap between the bristles of the side brush mechanism 20 and the bristles of the rotary brush 50 and failing to be smoothly sent into the garbage bin 60, resulting in garbage remaining inside the cleaning device 100.

[0055] On the basis of any of the above embodiments, the chassis 10 further includes a driving wheel set 14, and the driving wheel set 14 is arranged on the first upright column 12 and the second upright column 13. The driving wheel set 14 is specifically composed of a motor and a roller set, and is used to provide the power required for the movement of the cleaning device 100.

[0056] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0057] The above-described embodiments only represent several implementation manners of the present application, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
