[0022] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0023] In the present invention, unless otherwise stated, directional words such as "upper, lower, inside, outside" contained in a term merely represent the orientation of the term in normal usage, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0024] like Figure 1-3 As shown, a self-cleaning skylight comprises: an outer frame 1 and a pair of inclined rectangular sashes 2 symmetrically arranged on the top of the outer frame 1, each sash 2 is hinged with at least one electric push rod 3 hinged to the inside of the outer frame 1, and the outer frame 1 is equipped with a pair of cleaning units corresponding to the sashes 2, and each sash 2 is tilted downward away from the other sash 2. The long side is hinged to the outer frame 1;

[0025] The cleaning unit includes a cleaning mechanism 4 that can be slidably connected to the window sash 2 in a direction perpendicular to the hinge axis of the hinge, at least one set of elastic reset mechanisms assembled on the outer frame 1, and at least one connecting rope 5 with one end connected to the elastic reset mechanism and driving the cleaning mechanism 4 to slide when the window sash 2 is opened. The end of the connecting rope 5 away from the elastic reset mechanism is assembled on the outer frame 1 through a mounting mechanism.

[0026] When the electric push rod 3 drives the window sash 2 to open, the side of the window sash 2 away from the hinge will rotate upward, and the distance between the side of the window sash 2 away from the hinge and the top of the outer frame 1 will increase. Because one end of the connecting rope 5 is assembled on the outer frame 1 through the mounting mechanism, when the window sash 2 is opened, the connecting rope 5 will be twitched on the window sash 2, thereby driving the cleaning mechanism 4 to slide and clean the window sash 2. The other end of the connecting rope 5 is connected to the elastic reset mechanism; so when the window sash 2 rotates to return to its original position, the elastic reset mechanism will pull the connecting rope 5, and drive the cleaning mechanism 4 to slide on the window sash 2 to return to its original position through the connecting rope 5.

[0027] Every time the window sash 2 is opened and closed, the cleaning mechanism 4 can slide on one side of the window sash 2, that is, the opening and closing side of the window sash 2, and the cleaning mechanism 4 will complete two cleanings; especially after rain, there is still residual rainwater on the window sash 2, and the cleaning effect of the cleaning mechanism is better.

[0028] The elastic reset mechanism includes an arc-shaped rod 7 with both ends assembled on the outer wall of the outer frame 1 through a connecting seat 6, a sliding sleeve 8 slidably sleeved on the sliding rod and connected to the end of the connecting rope 5, and a spring 9 slidably sleeved on the arc-shaped rod 7 for pushing the sliding sleeve 8 to slide on the arc-shaped rod 7 away from the hinge. The middle part of the arc-shaped rod 7 is arranged close to the hinge.

[0029] When the window sash 2 is opened, the distance between the window sash 2 and the mounting mechanism increases, which will pull the connecting rope 5 to slide, and the connecting rope 5 will drive the sliding sleeve 8 to slide on the arc rod 7 close to the hinge, and the spring 9 is compressed; in the process of the window sash 2 returning to its original position, the spring 9 will push the sliding sleeve 8 to slide on the arc rod 7 to return to its original position, thereby pulling the connecting rope 5 to return to its original position, and the connecting rope 5 will pull the cleaning mechanism 4 to slide back to its original position.

[0030] Guide wheels 10 that are in sliding contact with the connecting rope 5 are provided on both ends of the short side of the window sash 2 opposite to the elastic reset mechanism, and the cleaning mechanism 4 is located between a pair of guide wheels 10 .

[0031] The cleaning mechanism 4 includes a connecting arm 11 arranged in the same length direction as the window sash 2, a rubber scraper 12 assembled on the connecting arm 11 in the same length direction and capable of contacting the window sash 2, and a pair of sliding members 13 respectively assembled on both ends of the connecting arm 11 and sliding along the width direction of the window sash 2. The sliding member 13 corresponding to the connecting rope 5 is connected to a connecting member 14 fixedly connected to the middle part of the connecting rope 5.

[0032] When the connecting rope 5 contacts and slides with the two guide wheels 10, it will drive the sliding member 13 to slide through the connecting member 14, thereby driving the connecting arm 11 and the rubber scraper 12 to slide. The rubber scraper 12 can scrape off some dust and other dirt.

[0033] The two short sides of the window sash 2 are fixedly equipped with strip slides 15 of the same length, and the strip slides 15 are penetrated by a strip slide groove of the same length and open at one end. The sliding member 13 is slidably assembled on the strip slide groove, and a limiting member 16 is detachably assembled on the open end of the strip slide groove.

[0034] The open end of the strip chute is used to assemble the sliding member 13 on the strip chute, and the limiting member 16 is used to prevent the sliding member 13 from slipping off from the open end of the strip chute.

[0035] The mounting mechanism includes a mounting seat 17 fixedly mounted on the outer frame 1 and having a mounting through hole for the connecting rope 5 to pass through, and at least one locking bolt 18 threadedly mounted on the mounting seat 17 and with its end capable of contacting the connecting rope 5 .
