Description

Technical Field

[0001] This utility model relates to the field of window cleaning robot technology, specifically to a cleaning mechanism for a window cleaning robot. Background Technology

[0002] As a type of service robot, window cleaning robots have made the cleaning and maintenance of large glass windows simple. Window cleaning robots use a cleaning cloth at the bottom to clean the surface of the glass.

[0003] Existing window cleaning robots have two sets of cleaning cloths at the bottom, and the sewn part of the cleaning cloths is installed on the outside of the rotating head through a slot. However, this connection method has poor stability. When the rotating head drives the cleaning cloth to wipe the glass, the large damping between the cleaning cloth and the glass will cause the rotation of the cleaning cloth to be hindered. Since the rotating head continues to rotate under the drive of the motor, the rotating head will spin freely inside the cleaning cloth, resulting in the cleaning cloth not achieving the desired cleaning effect.

[0004] Therefore, in order to solve the above problems, a cleaning mechanism for a window cleaning robot is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cleaning mechanism for a window cleaning robot to solve the problem mentioned in the background art where the cleaning cloth is installed on the outside of the rotating head through a slot. However, this connection method has poor stability, which causes the cleaning cloth to be obstructed when the rotating head drives the cleaning cloth to wipe the glass due to the large damping between the cleaning cloth and the glass. Meanwhile, the rotating head continues to rotate under the drive of the motor, so the rotating head will spin freely inside the cleaning cloth, resulting in the cleaning cloth failing to achieve the desired cleaning effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cleaning mechanism for a window cleaning robot, comprising: a shell, a top cover mounted on the top surface of the shell, a drive motor mounted on the inner side of the shell, and an obstacle avoidance sensor mounted on the outer wall of the shell; A cleaning structure is installed on the outer shell. The cleaning structure includes a rotating head, which is movably installed on the lower side of the outer shell. A slot is formed on the outer wall of the rotating head. An internal thread groove is formed on the upper end of the inner wall of the slot. A cleaning cloth sleeve is fitted on the outer side of the bottom end of the rotating head. A positioning pressure ring is movably installed on the inner side of the slot. Friction texture is integrally formed on the outer wall of the positioning pressure ring.

[0007] Preferably, the output end of the drive motor protrudes from the bottom surface of the housing and is fixedly connected to the center of the top surface of the rotating head.

[0008] Preferably, the depth of the slot is greater than the depth of the internal thread groove.

[0009] Preferably, the upper end of the cleaning cloth cover is engaged inside the slot.

[0010] Preferably, the inner wall of the positioning ring engages with the internal thread groove via a thread, and the bottom surface of the positioning ring abuts against the top surface of the cleaning cloth sleeve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a threaded positioning pressure ring on the inner wall of the slot, the positioning pressure ring can press on the upper end of the cleaning cloth sleeve, which can enhance the connection strength between the cleaning cloth sleeve and the rotating head, ensuring that the rotating head drives the cleaning cloth sleeve to rotate stably, thereby improving the cleaning effect on the glass. It is also convenient to assemble and disassemble and is more practical.

[0012] This invention features a cleaning structure that grips and rotates a positioning ring. The friction texture increases the gripping force, ensuring easy rotation of the positioning ring. The inner wall of the positioning ring engages with an internal threaded groove. During rotation, the positioning ring rises inside the groove, distancing its bottom surface from the inner wall of the groove and freeing up the lower end of the groove. A cleaning cloth is then placed on the outer side of the bottom of the rotating head, and the sewn part at the upper end of the cleaning cloth is elastically engaged inside the groove. At this point, the positioning ring is on top of the cleaning cloth. Reverse rotation of the positioning ring... The positioning ring engages with the internal threaded groove. When rotating, the positioning ring descends inside the groove, and its bottom surface presses against the top surface of the cleaning cloth. The positioning ring, in conjunction with the groove, compresses and fixes the upper end of the cleaning cloth, ensuring that the cleaning cloth rotates stably under the drive of the motor, thus guaranteeing the cleaning effect on the glass. Furthermore, the elasticity of the cleaning cloth acts as a reaction force on the positioning ring, maintaining a stable engagement between the positioning ring and the internal threaded groove. This prevents the positioning ring from loosening due to displacement of the cleaning cloth during the rotation of the rotating head, thereby improving the stability of the device.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 The present invention provides an embodiment of the cleaning mechanism for a window cleaning robot: The housing 1, top cover 11, drive motor 12, obstacle avoidance sensor 13 and rotating head 21 used in this application are products that can be purchased directly from the market. Their principles and connection methods are existing technologies well known to those skilled in the art, so they will not be described in detail here.

[0017] A window cleaning robot cleaning mechanism includes: a shell 1, a top cover 11 installed on the top surface of the shell 1, a drive motor 12 installed on the inner side of the shell 1, and an obstacle avoidance sensor 13 installed on the outer wall of the shell 1. A cleaning structure 2 is installed on the outer casing 1. The cleaning structure 2 includes a rotating head 21, which is movably installed on the lower side of the outer casing 1. A slot 22 is provided on the outer wall of the rotating head 21, and an internal thread groove 23 is provided on the upper end of the inner wall of the slot 22. A cleaning cloth sleeve 24 is fitted on the outer side of the bottom end of the rotating head 21. A positioning pressure ring 25 is movably installed on the inner side of the slot 22. Friction texture 26 is integrally formed on the outer wall of the positioning pressure ring 25. By setting the positioning pressure ring 25 with threaded connection on the inner wall of the slot 22, the positioning pressure ring 25 can press on the upper end of the cleaning cloth sleeve 24, which can enhance the connection strength between the cleaning cloth sleeve 24 and the rotating head 21, and ensure that the rotating head 21 drives the cleaning cloth sleeve 24 to rotate stably, thereby improving the cleaning effect on the glass. It is easy to disassemble and assemble, and is more practical.

[0018] Furthermore, the output end of the drive motor 12 is exposed on the bottom surface of the housing 1 and is fixedly connected to the center of the top surface of the rotating head 21. The drive motor 12 provides power for the rotation of the rotating head 21.

[0019] Furthermore, the depth of the slot 22 is greater than the depth of the internal thread groove 23, and the positioning pressure ring 25 can be sleeved on the outer side of the upper end of the cleaning cloth sleeve 24 to press the cleaning cloth sleeve 24 tightly and ensure the installation stability of the cleaning cloth sleeve 24 on the outside of the rotating head 21.

[0020] Furthermore, the upper end of the cleaning cloth cover 24 is secured inside the slot 22, which provides a connection for the installation of the cleaning cloth cover 24 on the outside of the rotating head 21. The positioning pressure ring 25 can improve the connection stability.

[0021] Furthermore, the inner wall of the positioning ring 25 engages with the internal thread groove 23 through threads, and the bottom surface of the positioning ring 25 abuts against the top surface of the cleaning cloth sleeve 24. When the positioning ring 25 rotates, it can move up and down inside the slot 22 with the cooperation of the internal thread groove 23, so as to clamp and loosen the cleaning cloth sleeve 24, and realize the convenient installation and removal of the cleaning cloth sleeve 24 on the outside of the rotating head 21.

[0022] Working principle: During installation, hold and rotate the positioning ring 25. The friction texture 26 increases the gripping force of the positioning ring 25, ensuring easy rotation. The inner wall of the positioning ring 25 engages with the internal thread groove 23. When rotating, the positioning ring 25 rises inside the slot 22, causing the bottom surface of the positioning ring 25 to move away from the inner wall of the slot 22, freeing up the lower end of the slot 22. The cleaning cloth cover 24 is then placed on the outer side of the bottom of the rotating head 21, allowing the upper sewn part of the cleaning cloth cover 24 to be secured inside the slot 22 under elasticity. At this point, the positioning ring 25 is above the cleaning cloth cover 24. Reverse rotation of the positioning ring 25 then positions the ring. The positioning pressure ring 25 engages with the internal thread groove 23. When rotating, the positioning pressure ring 25 descends inside the slot 22, and the bottom surface of the positioning pressure ring 25 presses against the top surface of the cleaning cloth sleeve 24. The positioning pressure ring 25, together with the slot 22, can squeeze and fix the upper end of the cleaning cloth sleeve 24, ensuring that when the rotating head 21 rotates under the drive of the drive motor 12, it can drive the cleaning cloth sleeve 24 to rotate stably, ensuring the cleaning effect on the glass. Moreover, the cleaning cloth sleeve 24 is elastic and can react to the positioning pressure ring 25, so that the engagement between the positioning pressure ring 25 and the internal thread groove 23 remains stable, preventing the cleaning cloth sleeve 24 from shifting and causing the positioning pressure ring 25 to loosen when the rotating head 21 rotates, thus improving the stability of the device.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
