Abstract
Description
Technical Field
[0001] The invention relates to a cleaning robot and belongs to the technical field of small household appliance manufacturing. Background Art
[0002] Currently, for sweeping robots with mopping functions on the market, the rag holder can only descend by its own gravity, or is completely fixed and cannot move. When encountering obstacles such as steps, it cannot be lifted upwards, causing the rag and the rag holder to hit the obstacle and cause the machine to get stuck, greatly reducing cleaning efficiency.
[0003] A Chinese patent application with application number 201710451102.9 discloses a mopping robot, including a bracket and an elastomer. The bracket has an arc-shaped side wall, so that the bracket can be smoothly lifted by a protrusion on the ground, thereby reducing the chance of the rag and the rag bracket being stuck. However, since the bracket cannot be deformed, when the bracket is lifted by the protrusion, it is separated from the ground, and the ground around the protrusion cannot contact the rag and cannot be effectively cleaned. In addition, since there is a gap between the side wall and the tray, when the height of the obstacle is between the side wall and the tray, the machine will still get stuck, reducing the working efficiency of the robot and giving the user a poor experience. Summary of the invention
[0004] The technical problem to be solved by the present invention is to provide a cleaning robot in view of the shortcomings of the prior art. By increasing the height of the tilting part and arranging a soft body between the tilting part and the rag bracket, the application range of the cleaning robot is improved, the cleaning robot can cross higher obstacles and enhance the cleaning efficiency.
[0005] The technical problem to be solved by the present invention is achieved through the following technical solutions:
[0006] The present invention provides a cleaning robot, comprising a rag holder, a rag is provided below the rag holder, the rag holder is arranged at the bottom of a base so as to float up and down through an elastic member, the front end of the rag holder is connected to a tilting portion through a soft body, and the tilting portion contacts the bottom of the base.
[0007] Preferably, the raised portion is an inclined surface or a curved surface.
[0008] Preferably, the soft body is a spring sheet, a cloth cover or rubber.
[0009] In order to make the tilting part contact with the base, the tilting part is connected to the bottom of the base by gluing, riveting or snapping. Alternatively, the tilting part relies on the supporting force provided by the soft body to press against the base.
[0010] In order to achieve a better cleaning effect, the rag support is at least partially composed of a plurality of soft supports.
[0011] Preferably, the flexible bracket is in a strip shape, the length direction of which is perpendicular to the forward direction of the cleaning robot, and a plurality of flexible brackets are arranged at intervals along the forward direction of the cleaning robot.
[0012] Preferably, the flexible bracket is triangular and evenly spaced on the rag bracket.
[0013] In order to prevent the soft body and the raised portion from being contaminated by dirt, the lower parts of the soft body and the raised portion are wrapped with a rag.
[0014] Preferably, one end of the elastic member abuts against the rag bracket, and the other end abuts against the bottom of the base.
[0015] In summary, the present invention improves the application range of the cleaning robot by increasing the height of the tilting portion and providing a soft body between the tilting portion and the rag bracket, so that the cleaning robot can overcome obstacles of higher heights and enhance the cleaning efficiency.
[0016] The technical solution of the present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
[0017] Figure 1 It is a structural schematic diagram of the rag bracket of the present invention;
[0018] Figure 2 for Figure 1 AA section view;
[0019] Figure 3 It is a structural schematic diagram of the rag support of the present invention being assembled on a base. DETAILED DESCRIPTION
[0020] like Figures 1 to 3 As shown, the present invention provides a cleaning robot, wherein an elastic member 110 and a rag holder 200 are provided on a base 100 of the cleaning robot, one end of the elastic member 110 abuts against the rag holder 200, and the other end abuts against the bottom of the base 100, the rag holder 200 is arranged at the bottom of the base 100 so as to float up and down through the elastic member 110, and a rag 300 is further provided below the rag holder 200. With the forward direction B of the cleaning robot as the front, the front end of the rag holder 200 is connected to a tilting portion 220 through a soft body 210, and the tilting portion 220 is in contact with the bottom of the base 100.
[0021] The soft body 210 will deform when subjected to a force. Preferably, the soft body 210 is a spring, a cloth cover or rubber. The shape of the raised portion 220 is preferably an inclined surface (i.e., the raised portion 220 is a plane, and there is an angle between the plane and the ground) or an arc surface (e.g., Figure 2 and Figure 3The tilting portion 220 may contact the bottom of the base 100 in a variety of ways. For example, the tilting portion 220 may be connected to the bottom of the base 100 by gluing, riveting or snapping, or the tilting portion 220 may be pressed against the base 100 by the support force provided by the soft body 210.
[0022] When the height of the obstacle in front of the cleaning robot is higher than the lowest height of the base 100, the detection unit located on the base 100 of the cleaning robot can detect the direction of the obstacle and send a detection signal to the control unit of the cleaning robot, thereby guiding the cleaning robot to walk around the obstacle; when the height of the obstacle in front of the cleaning robot is lower than the lowest height of the base 100, since the tilting portion 220 is in contact with the bottom of the base 100, the obstacle comes into contact with the tilting portion 220 during the cleaning robot's walking towards the obstacle, and the obstacle pushes the tilting portion 220 upward When the lifting portion 220 is lifted up by an obstacle, the position of the rag holder 200 does not change due to the existence of the soft body 210, thereby ensuring that the rag 300 is always in contact with the ground. Compared with the rag holder that is directly lifted up when encountering an obstacle, the cleaning robot in the present invention can wipe a wider area and has a better cleaning effect when dealing with dirt near the obstacle.
[0023] As the cleaning robot continues to move forward, the obstacle continues to push the raised portion 220 upward, and when the soft body 210 reaches its deformation limit, the end connected to the rag holder 200 rises with the raised portion 220, thereby driving the rag holder 200 to rise, allowing the rag holder 200 to pass over the obstacle.
[0024] In order to achieve a better cleaning effect, the rag holder 200 is at least partially composed of a plurality of soft holders 201. Preferably, the material of the soft holder 201 is the same as that of the soft body 210, which may be a spring, a cloth cover or rubber.
[0025] The present invention does not limit the specific structure of the flexible bracket 201. For example, the flexible bracket 201 may be in a strip shape, the length direction of which is perpendicular to the forward direction B of the cleaning robot, and a plurality of flexible brackets 201 are arranged at intervals along the forward direction B of the cleaning robot. The flexible bracket 201 may also be in a triangular shape, which is evenly spaced and distributed on the rag bracket 200 (e.g. Figure 1 shown).
[0026] In order to prevent the soft body 210 and the tilting portion 220 from being contaminated by dirt, preferably, the lower part of the soft body 210 and the tilting portion 220 is wrapped with a rag 300 .
[0027] The working process of the cleaning robot of the present invention is described below in conjunction with specific scenarios.
[0028] For example, when a cleaning robot cleans a shopping mall, there may be underground lights or pop-up floor plugs and other protrusions on the floor of the shopping mall. In a traditional cleaning robot, there is a gap between the side wall of the floor brush holder and the robot base. When the height of the pop-up floor plug is between the gap, the pop-up floor plug contacts the side wall of the floor brush holder and the pop-up floor plug will block the floor brush holder from moving forward. In the present invention, since the tilting portion 220 contacts the bottom of the base 100, there is no gap between the tilting portion 220 and the bottom of the base 100. Therefore, the pop-up floor plug and other protrusions can always provide an upward force for the tilting portion 220 to lift the tilting portion 220.
[0029] On the other hand, the floor brush holder of a conventional cleaning robot is generally made of hard plastic or other materials. Even if the height of the pop-up floor plug is lower than the height of the side wall of the floor brush holder, the floor brush holder rises as a whole during the process of being lifted up, so that the rag cannot contact the ground near the pop-up floor plug, and the dirt around the protrusion cannot be effectively cleaned. The present invention provides a deformable soft body 210 between the tilting portion 220 and the rag holder 200, so that when the tilting portion 220 is lifted up, the rag 300 under the rag holder 200 still remains in contact with the ground, thereby expanding the cleaning range of the cleaning robot.
[0030] Furthermore, since the rag holder 200 is at least partially composed of multiple soft holders 201, in the process of the rag holder 200 passing over the pop-up floor plug, only the rag holder 200 near the top of the pop-up floor plug is lifted up by the pop-up floor plug, and the rag holder 200 in other parts descends by its own gravity with the help of the deformable soft holder 201, so that the rag remains in contact with the ground, effectively cleaning the dirt around the pop-up floor plug.
[0031] In summary, the present invention improves the application range of the cleaning robot by increasing the height of the tilting portion and providing a soft body between the tilting portion and the rag bracket, so that the cleaning robot can overcome obstacles of higher heights and enhance the cleaning efficiency.
