[0024] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0026] The cleaning robot provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.
[0027] Please refer to Figure 1-Figure 7 The cleaning robot disclosed in the embodiment of the present application includes a shell 100, a cleaning brush 200 and a driving source 300, wherein the shell 100 serves as a supporting component of the cleaning robot, and the shell 100 provides support for other components. The cleaning brush 200, the driving source 300 and other working components can all be arranged in the shell 100. Specifically, an installation space is provided in the shell 100, and the cleaning brush 200, the driving source 300 and other working components are all arranged in the installation space; the cleaning brush 200 can rotate relative to the shell 100 to clean the floor; the driving source 300 is connected to the cleaning brush 200, and the driving source 300 can drive the cleaning brush 200 to rotate to provide rotational power to the cleaning brush 200.
[0028] Optionally, the cleaning brush 200 may be a roller brush, such as Figure 2 and Figure 3 As shown, the shell 100 is provided with a dust collecting port 101 , which is connected to the location of the cleaning brush 200 . When the driving source 300 drives the cleaning brush 200 to rotate to clean the dirt, the dirt on the ground is collected through the dust collecting port 101 .
[0029] The driving source 300 includes a driving body 310 and a driving shaft connected to each other. The driving body 310 is disposed on the housing 100. Optionally, the driving body 310 and the housing 100 can be connected by welding, bonding, etc. The driving shaft is connected to the end of the cleaning brush 200 to drive the cleaning brush 200 to rotate relative to the housing 100. Optionally, the driving source 300 can be a driving structure that can provide rotational power, such as a driving motor and a pneumatic motor.
[0030] Optionally, a brush shaft is provided at the end of the cleaning brush 200, and the driving shaft can be directly or indirectly connected to the brush shaft. Figure 2-Figure 4 As shown, the cleaning robot may further include a transmission structure 600, through which the drive shaft is indirectly connected to the brush shaft of the cleaning brush 200. The transmission structure 600 may be a deceleration structure using gear transmission, belt transmission, etc., to avoid the drive shaft being directly connected to the cleaning brush 200, resulting in an excessively high rotation speed of the cleaning brush 200.
[0031] refer to Figure 1 and Figure 6 As shown, the cleaning robot further includes a first blocking member 400, which is connected to the housing 100 and is located at the end of the cleaning brush 200. A first gap 410 is formed between the first blocking member 400 and the circumference of the cleaning brush 200 for the cleaning brush 200 to rotate, so as to prevent foreign matter from entering the driving shaft through the first gap 410. In other words, the purpose of setting the first gap 410 is to prevent the first blocking member 400 from directly contacting the cleaning brush 200 and affecting the normal rotation of the cleaning brush 200. Therefore, the first gap 410 is relatively small, and the first blocking member 400 can effectively prevent foreign matter from passing through the first gap 410. The circumference of the cleaning brush 200 is far away from the brush shaft. If a foreign matter passes through the first gap 410, it needs to further approach the brush shaft along the radial direction of the cleaning brush 200 to reach the position of the driving shaft. Therefore, the first blocking member 400 prevents foreign matter from passing through the first gap 410, and can also prevent foreign matter from moving to the driving shaft along the radial direction of the cleaning brush 200. Optionally, the first blocking member 400 may be made of a hard material such as plastic, or a soft material with elasticity such as rubber.
[0032] Optionally, the first blocking member 400 and the shell 100 may be formed into an integral structure by injection molding; or, the first blocking member 400 and the shell 100 may be a split structure. Further optionally, the first blocking member 400 and the shell 100 may be connected by welding, bonding, etc.
[0033] refer to Figure 1 as well as Figure 5-Figure 7As shown, the cleaning robot further includes a second blocking member 500, which is protruding relative to the circumference of the cleaning brush 200, and the second blocking member 500 blocks foreign matter from entering the drive shaft along the axial direction of the cleaning brush 200. Optionally, the second blocking member 500 can be directly disposed on the circumference of the cleaning brush 200 and protrude from the circumference of the cleaning brush 200; or, the second blocking member 500 is disposed on the housing 100, and the second blocking member 500 adopts a soft structure such as bristles 520, and the second blocking member 500 contacts the circumference of the cleaning brush 200, thereby blocking foreign matter from entering the drive shaft along the axial direction of the cleaning brush 200.
[0034] In the embodiment of the present application, the first gap 410 between the first blocking member 400 and the circumferential surface of the cleaning brush 200 is very small, which can only prevent the first blocking member 400 from directly contacting the cleaning brush 200 and affecting the normal rotation of the cleaning brush 200. Therefore, the first blocking member 400 can prevent foreign matter from passing through the first gap 410, thereby preventing the foreign matter from moving radially along the cleaning brush 200 to the drive shaft; at the same time, the second blocking member 500 is protruding relative to the circumferential surface of the cleaning brush 200, and the second blocking member 500 can directly prevent the foreign matter entangled with the cleaning brush 200 from moving axially along the cleaning brush 200, thereby preventing the foreign matter from entering the drive shaft.
[0035] Therefore, the embodiment of the present application combines the first blocking member 400 and the second blocking member 500 to block foreign matter from entering the drive shaft from the radial direction of the cleaning brush 200 and the axial direction of the cleaning brush 200, thereby avoiding affecting the working process of the driving source 300 and ensuring the service life of the driving source 300.
[0036] In an optional embodiment, the first blocking member 400 is a blocking rib, which is a hard structure and a block structure, and the blocking rib only forms a first gap 410 with a certain position of the circumference of the cleaning brush 200. In this embodiment, the blocking rib and the housing 100 are an integrally formed structure.
[0037] In another embodiment, reference Figure 1 and Figure 6 As shown, the retaining rib is a strip structure, and the retaining rib extends along the circumference of the cleaning brush 200. Optionally, the retaining rib may be an annular structure or an arc structure. With this embodiment, the retaining rib may form a first gap 410 with different positions of the circumference of the cleaning brush 200 to block foreign matter from passing through the first gap 410 from different positions, which is conducive to improving the blocking effect and more effectively preventing foreign matter from entering the drive shaft.
[0038] In a further embodiment, the retaining rib is an annular structure, the retaining rib is arranged around the cleaning brush 200, and the first gap 410 is an annular gap. Optionally, the housing 100 is provided with a receiving cavity and a slot, the receiving cavity is used to receive the main body of the cleaning brush 200, and the end of the cleaning brush 200 can extend into the slot, and the retaining member with an annular structure is arranged at the opening of the slot to surround the cleaning brush 200.
[0039] With this embodiment, the retaining ribs and various positions of the circumference of the cleaning brush 200 form a first gap 410, which effectively prevents foreign matter flying from various directions of the cleaning brush 200 from passing through the first gap 410, thereby maximizing the blocking effect and further effectively preventing foreign matter from entering the drive shaft.
[0040] Of course, in other embodiments, the retaining ribs may be an arc-shaped structure, that is, the retaining ribs are only disposed around a portion of the cleaning brush 200 , and the first gap 410 is an arc-shaped gap.
[0041] In an optional embodiment, the number of the first blocking member 400 is one, such as Figure 3 and Figure 4 As shown, the cleaning brush 200 has a first end 210 and a second end 220 , and the first blocking member 400 is located at the position where the first end 210 is located or the position where the second end 220 is located.
[0042] In another embodiment, reference Figure 6 As shown, the number of the first blocking members 400 is at least two, wherein the two first blocking members 400 are respectively located at the two ends of the cleaning brush 200, and each first blocking member 400 forms a first gap 410 with the circumference of the cleaning brush 200, that is, the two first blocking members 400 are respectively located at the position where the first end 210 is located and the position where the second end 220 is located. The embodiment of the present application does not limit the number of the first blocking members 400.
[0043] By adopting this embodiment, at least two first blocking members 400 can respectively block foreign matter from passing through the corresponding first gaps 410 and reaching the brush shaft position of the cleaning brush 200 from the two ends of the cleaning brush 200, thereby avoiding affecting the normal rotation process of the cleaning brush 200, which is conducive to the continuous and smooth operation of the cleaning robot.
[0044] In the scheme of this application, reference is made to Figure 5-Figure 7As shown, the second blocking member 500 includes a mounting member 510 and bristles 520. The mounting member 510 is connected to the housing 100. The mounting member 510 is used to mount the bristles 520. The bristles 520 are arranged on the mounting member 510, and the mounting member 510 is equivalent to a bristle holder. Moreover, the bristles 520 are in contact with the peripheral surface of the cleaning brush 200. Specifically, the mounting member 510 is provided with a bristle hole for one end of the bristles 520 to extend into, and the other end of the bristles 520 is in contact with the peripheral surface of the cleaning brush 200. Optionally, the mounting member 510 can be fixedly connected to the housing 100 by welding, bonding or other non-detachable means. The bristles 520 can be in a strip structure or a sheet structure. Since the bristles 520 are relatively soft and can be deformed, even if the bristles 520 are in contact with the cleaning brush 200, the rotation process of the cleaning brush 200 will not be affected.
[0045] This embodiment uses bristles 520 with variable shapes, which are in contact with the peripheral surface of the cleaning brush 200, which is more conducive to cleaning foreign matter such as hair entangled with the cleaning brush 200, and is conducive to improving the blocking effect of foreign matter, and effectively preventing foreign matter from entering the driving shaft. In addition, the second blocking member 500 is arranged on the housing 100, and there is no need to arrange the second blocking member 500 on the peripheral surface of the cleaning brush 200, so as to avoid affecting the structure of the cleaning brush 200.
[0046] In an optional embodiment, the mounting member 510 is detachably connected to the housing 100. Optionally, the mounting member 510 and the housing 100 may be detachably connected by bolt connection, snap connection, etc., and the embodiment of the present application does not limit the detachable connection method between the mounting member 510 and the housing 100.
[0047] With this embodiment, the user can install and remove the installation member 510 as needed, thereby achieving installation and removal of the bristles 520 , which is conducive to regular replacement of the bristles 520 .
[0048] In an optional embodiment, the number of the second blocking member 500 may be one. The embodiment of the present application does not limit the location of the second blocking member 500 in the axial direction of the cleaning brush 200, as long as it can block the axial movement of the foreign matter entangled by the cleaning brush 200.
[0049] In another embodiment, reference Figure 5-Figure 7 As shown, there are at least two second blocking members 500, each of which is spaced apart along the axial direction of the cleaning brush 200. Optionally, the cleaning brush 200 has a first end 210 and a second end 220, wherein the two second blocking members 500 are respectively located at the first end 210 and the second end 220 of the cleaning brush 200.
[0050] By adopting this embodiment, at least two second blocking members 500 are used to block the movement of foreign matter entangled with the cleaning brush 200 at different positions in the axial direction of the cleaning brush 200, which is beneficial to improving the blocking effect of foreign matter and more effectively preventing foreign matter from entering the drive shaft.
[0051] In an optional embodiment, the cleaning brush 200 has a first end 210 and a second end 220. Along the axial direction of the cleaning brush 200, the distance between the second blocking member 500 and the first end 210 is smaller than the distance between the second blocking member 500 and the second end 220. That is, the distance between the second blocking member 500 and the second end 220 is larger, and the second blocking member 500 is closer to the first end 210. Moreover, along the axial direction of the cleaning brush 200, the distance between the second blocking member 500 and the first end 210 is greater than or equal to the distance between the second blocking member 500 and the center of the cleaning brush 200. That is, the distance between the second blocking member 500 and the first end 210 is larger, and the second blocking member 500 is closer to the center of the cleaning brush 200.
[0052] It should be noted that, along the axial direction of the cleaning brush 200 , the distance between the center of the cleaning brush 200 and the first end 210 of the cleaning brush 200 is equal to the distance between the center of the cleaning brush 200 and the second end 220 of the cleaning brush 200 .
[0053] In another embodiment, the distance between the second blocking member 500 and the first end 210 is smaller than the distance between the second blocking member 500 and the center of the cleaning brush 200. In other words, the distance between the second blocking member 500 and the center of the cleaning brush 200 is larger, and the second blocking member 500 is closer to the first end 210.
[0054] Compared with the previous embodiment, the second blocking member 500 of the latter embodiment is closer to the first end 210 of the cleaning brush 200. Therefore, along the axial direction of the cleaning brush 200, foreign objects in the area between the second blocking member 500 and the second end 220 of the cleaning brush 200 can be blocked by the second blocking member 500, thereby further improving the blocking effect and effectively preventing foreign objects entangled in the cleaning brush 200 from moving axially to the drive shaft.
[0055] In the embodiment where the number of the second blocking members 500 is at least two, one of the second blocking members 500 can meet the above condition, that is, along the axial direction of the cleaning brush 200, the distance between one of the second blocking members 500 and the first end 210 is smaller than the distance between the second blocking member 500 and the second end 220, and the distance between the second blocking member 500 and the first end 210 is smaller than the distance between the second blocking member 500 and the center of the cleaning brush 200; and the distance between the other second blocking member 500 and the second end 220 is smaller than the distance between the second blocking member 500 and the first end 210, and the distance between the second blocking member 500 and the second end 220 is smaller than the distance between the second blocking member 500 and the center of the cleaning brush 200. In other words, one of the second blocking members 500 is closer to the first end 210, and the other second blocking member 500 is closer to the second end 220.
[0056] In a further embodiment, the second blocking member 500 is located at the end of the cleaning brush 200. Optionally, the number of the second blocking member 500 is one, and the second blocking member 500 can be located at the first end 210 or the second end 220 of the cleaning brush 200; or, the number of the second blocking member 500 is at least two, wherein the two second blocking members 500 are respectively located at the first end 210 and the second end 220 of the cleaning brush 200. In other words, the distance between the second blocking member 500 and the end to which it is close is zero, and the distance between the second blocking member 500 and the center of the cleaning brush 200 is half the length of the cleaning brush 200.
[0057] By adopting this embodiment, the second blocking member 500 is brought closer to the end of the cleaning brush 200. Therefore, along the axial direction of the cleaning brush 200, foreign matter in the area between the second blocking member 500 and the end of the cleaning brush 200 away from it can be blocked from moving by the second blocking member 500, which is beneficial to further enhance the blocking effect and effectively prevent foreign matter entangled with the cleaning brush 200 from moving axially to the drive shaft, thereby ensuring the smooth and normal operation of the drive source 300.
[0058] Of course, in other embodiments, the second blocking member 500 may not be located at the end of the cleaning brush 200 , that is, the second blocking member 500 is located between the first end 210 of the cleaning brush 200 and the second end 220 of the cleaning brush 200 .
[0059] In an optional embodiment, the second blocking member 500 is disposed on the peripheral surface of the cleaning brush 200, and the second blocking member 500 is a block structure.
[0060] In another embodiment, the second blocking member 500 extends in the radial direction of the cleaning brush 200. Optionally, the second blocking member 500 is a strip structure extending in the radial direction of the cleaning brush 200, and the second blocking member 500 can be arranged on the peripheral surface of the cleaning brush 200, or the second blocking member 500 is arranged on the housing 100. In this embodiment, since the second blocking member 500 extends in the radial direction of the cleaning brush 200, it means that the size of the second blocking member 500 in the radial direction of the cleaning brush 200 is large, and the blocking area of the second blocking member 500 is increased, which is more conducive to blocking the foreign matter entangled by the cleaning brush 200 from moving in the axial direction of the cleaning brush 200, and further improving the blocking effect of the foreign matter.
[0061] The embodiments of the present application are described above in conjunction with the accompanying drawings, but the present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.
