When the cleaning robot 1000 is in operation, a user can directly view the working condition of the rolling brush 200 during rotation through the observation area 130, the observation space 140 and the transparent area 120, so that the user can more intuitively know the working state of the rolling brush 200 of the robot, and the user can find whether the rolling brush 200 works abnormally in time. Because the observation area 130 and the transparent area 120 are communicated through the closed observation space 140, dust is not easy to enter the observation space 140 communicating the observation area 130 and the transparent area 120, and the observation space 140 can keep a good perspective effect for a long time.

In view of the fact that the cleaning robot 1000 has more parts, in order to facilitate the assembly of the cleaning robot 1000, the housing 100 of the cleaning robot 1000 is generally formed by connecting a plurality of parts, and in particular, referring to fig. 1 and 2 or fig. 4 and 5, the housing 100 includes an upper cover 150, a middle sweeping bracket 160 and a lower cover 170, the upper cover 150 is mounted above the lower cover 170 and surrounds the lower cover 170 to form an accommodating space, the middle sweeping bracket 160 is assembled to the lower cover 170, and a mounting cavity 110 with an open bottom is formed on the middle sweeping bracket 160.

Since the mounting cavity 110 is formed on the middle-scan holder 160, the transparent area 120 is formed on the middle-scan holder 160, and since the upper cover 150 covers the entire lower cover 170 and the middle-scan holder 160, the observation area 130 is formed at a position where the upper cover 150 is located above the middle-scan holder 160, and the closed observation space 140 is correspondingly formed between the upper cover 150 and the lower cover 170.

It should be noted that there are various ways to form the observation space 140, and in some embodiments of the present invention, the observation space 140 is formed by a cavity structure formed by the upper cover 150, the lower cover 170, the middle-sweeping support 160 and the plate structure. Specifically, referring to fig. 1 and 2, the middle-sweeping support 160 is hermetically connected to the lower cover 170, the upper cover 150 is hermetically connected to the lower cover 170, and the cleaning robot 1000 further includes a partition 800, wherein the partition 800, the upper cover 150, the lower cover 170, and the middle-sweeping support 160 respectively enclose the observation space 140.

Further, both ends of the partition 800 in the length direction thereof and the side of the partition 800 away from the middle-scanning support 160 are covered with a sealing strip (not shown), which can effectively seal the partition 800 with the upper cover 150 under the compression of the upper cover 150 when the upper cover 150 is assembled to the lower cover 170, so that the partition 800 and the upper cover 150 can be hermetically connected.

In other embodiments of the present invention, the observation space 140 is formed by a tubular structure enclosing the upper cover 150 and the middle sweeping support 160. Specifically, referring to fig. 4 and 5, the cleaning robot 1000 further includes a connecting member 900, the connecting member 900 is provided with an observation channel 910 in a penetrating manner, the observation channel 910 is a linear channel or a channel close to a linear channel, one end of the connecting member 900 abuts against the upper cover 150, the other end of the connecting member 900 abuts against the middle-sweeping bracket 160, so that one end of the observation channel 910 is aligned with the transparent area 120, and the other end of the observation channel 910 is aligned with the observation area 130.

It should be noted that the observation space 140 is disposed in a sealed manner, so that the connecting element 900 needs to be connected to the upper cover 150 in a sealing manner, the connecting element 900 and the upper cover 150 can be sealed by a sealing adhesive, the connecting element 900 and the upper cover 150 can also be sealed by a sealing gasket, and the connecting element 900 and the upper cover 150 can also be connected in a sealing manner by other manners, which are not listed here.

Preferably, the connection member 900 is connected to the upper cover 150 in a sealing manner by a sealing ring 950, and the sealing ring 950 is pressed by the upper cover 150 and the middle scavenging supporter 160 simultaneously when the connection member 900 is assembled between the upper cover 150 and the middle scavenging supporter 160, so that the sealing ring 950 can be in sealing abutment with the upper cover 150 and the middle scavenging supporter 160, thereby eliminating the gap between the upper cover 150 and the connection member 900.

Further, referring to fig. 7, a positioning groove 951 extending along the circumferential direction of the sealing ring 950 is recessed from a surface of the sealing ring 950 opposite to the upper cover 150, and the positioning groove 951 is used for being inserted into and matched with an end of the connecting member 900 adjacent to the transparent region 120, so that the connecting member 900 and the sealing ring 950 can be conveniently assembled, and the sealing ring 950 can be conveniently assembled between the connecting member 900 and the upper cover 150.

It should be noted that the connection member 900 is also connected to the middle-scan holder 160 in a sealing manner, and the sealing manner between the connection member 900 and the middle-scan holder 160 can be referred to as the sealing manner between the connection member 900 and the upper cover 150. Preferably, referring to fig. 6, the connecting member 900 is integrally formed with the middle-sweeping support 160, so that the connecting strength between the connecting member 900 and the middle-sweeping support 160 is ensured, and the sealing performance between the connecting member 900 and the middle-sweeping support 160 is also ensured.

In some other embodiments of the present invention, the observation space 140 is formed by a transparent bag structure, and specifically, the cleaning robot 1000 further includes an elastic airbag (not shown) made of a transparent material, the elastic airbag is installed between the upper cover 150 and the middle broom bracket 160, and the elastic airbag abuts against the transparent area 120 and the observation area 130, respectively, to form the observation space 140.

It should be noted that the elastic air bag can still generate a certain elastic deformation after being inflated, so that when the elastic air bag is assembled between the middle-scan bracket 160 and the upper cover 150, the elastic air bag can generate an elastic deformation by being pressed between the middle-scan bracket 160 and the upper cover 150, so that the elastic air bag can be abutted against the observation region 130 of the upper cover 150 and the transparent region 120 of the middle-scan bracket 160, thereby facilitating the formation of the observation space 140.

Considering that a part of air in the elastic airbag may be lost after the elastic airbag is used for a long time, in view of this, the cleaning robot 1000 further includes an air pump (not shown) and an air pressure detection device (not shown), the air pressure detection device is used for detecting air pressure in the elastic airbag, the air pump is communicated with the elastic airbag pipeline, a one-way valve (not shown) is further disposed on the pipeline connecting the air pump and the elastic airbag to ensure that air can only enter the elastic airbag, the air pump and the air pressure detection device are both electrically connected with the main control module 500 of the cleaning robot 1000, and the main control module 500 controls the air pump to operate according to the air pressure detection device.

When the real-time air pressure value in the elastic air bag detected by the air pressure detection device is lower than the preset air pressure value, the main control module 500 controls the air pump to start to inflate the elastic air bag; when the real-time air pressure value in the elastic air bag detected by the air pressure detection device of the main control module 500 is equal to or greater than the preset air pressure value, the main control module 500 controls the air pump to stop working. With this arrangement, the elastic airbag can be ensured to be always in contact with the transparent region 120 and the observation region 130, thereby ensuring that the transparent region 120 and the observation region 130 are always communicated through a sealed observation space 140.

Based on the above embodiments, it should be noted that the housing 100 of the cleaning robot 1000 has a certain thickness, and if the observation region 130 is provided at the top of the housing 100 and the transparent region 120 is provided at the bottom of the housing 100, the height of the observation space 140 communicating the observation region 130 and the transparent region 120 is high. In view of this, in some embodiments of the present invention, the distance between the viewing area 130 and the transparent area 120 is reduced to reduce the height of the viewing space 140.

Specifically, referring to fig. 1 and 8 or fig. 4 and 8, the housing 100 has a front end and a rear end opposite to each other in the traveling direction of the cleaning robot 1000, the front end of the housing 100 protrudes forward to form a protrusion 180 adjacent to the ground, the mounting cavity 110 is at least partially formed on the protrusion 180, the transparent area 120 is disposed below the protrusion 180, and the observation area 130 is formed on the protrusion 180.

It should be noted that when the housing 100 is composed of the upper cover 150, the lower cover 170 and the middle-sweeping bracket 160, the front end of the upper cover 150 protrudes forward at a position adjacent to the lower cover 170, and the front end of the lower cover 170 extends forward correspondingly, and the two are connected to form the protruding portion 180.

When the partition 800 or the connector 900 is formed to surround the upper cover 150, the lower cover 170, and the middle-sweeping support 160, a part of the partition 800 or the connector 900 extends from the middle-sweeping support 160 toward the upper cover 150 and abuts against a position where the front end of the upper cover 150 is not protruded, so that the observation space 140 is formed in the protrusion 180.

Since the thickness of the protrusion 180 is smaller than that of the housing 100, the height of the observation space 140 can be effectively reduced, and the observation space 140 is disposed at the position of the protrusion 180, thereby preventing the installation of other components of the cleaning robot 1000 from being affected by the disposition of the observation space 140.

In addition, the mounting cavity 110 is partially formed in the protrusion 180, which allows the rolling brush 200 to be further disposed toward the front end of the housing 100, and since the protrusion 180 is disposed lower than the top of the housing 100, the cleaning robot 1000 can effectively clean the space below the sanding, the cabinet, and other objects, which also solves the problem that the cleaning robot 1000 cannot clean the space below the housing 100 due to the excessively high height of the housing 100.
