DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0021] See also Figure 1-5 The utility model provides a technical solution: a projection decorative lamp, comprising a base 10, a liquid storage tank 20 is fixedly mounted on the upper surface of the base 10, a support frame 30 is fixedly mounted on the upper surface of the liquid storage tank 20, a lamp 40 is provided on the top of the support frame 30, a light surface 41 is provided at the center of one end of the lamp 40, and the light surface 41 is the output port of the light source of the lamp 40. In order to ensure the effect of the projection light, it is often necessary to clean the light surface 41.

[0022] The side of the liquid storage tank 20 is provided with an infusion pump 21, and the output end of the infusion pump 21 is provided with a bellows telescopic tube 22. The end of the bellows telescopic tube 22 passes through the L-shaped plate 70 and is connected to the spray head 90. When the lighting surface 41 needs to be cleaned, under the premise that the liquid storage tank 20 is filled with cleaning liquid, the cleaning liquid in the liquid storage tank 20 is pumped into the bellows telescopic tube 22 through the operation of the infusion pump 21, and the bellows telescopic tube 22 transports the cleaning liquid into the spray head 90, and the spray head 90 sprays the cleaning liquid. At this time, the L-shaped plate 70 is driven to rise and fall by the operation of the electric cylinder 60. Since the bellows telescopic tube 22 is elastic, the L-shaped plate 70 will drive the spray head 90 to rise and fall together. During the process of lifting the spray head 90, the cleaning liquid will first be sprayed onto the surface of the lighting surface 41, which is conducive to washing away large particles of dust and impurities on the lighting surface 41 and ensuring the lubrication of the lighting surface 41 to avoid scratching and damaging the lighting surface 41 during the cleaning process.

[0023] Among them, the cleaning component includes a telescopic rod 81 fixedly installed on the inner top end of the L-shaped plate 70, and a scraper 80 is provided at the end of the telescopic rod 81. The scraper bar 80 compresses the telescopic rod 81, and then combined with the elastic force of the telescopic rod 81, it is conducive to driving the scraper bar 80 to fit closely on the surface of the lamp surface 41, so that the scraper bar 80 has a better cleaning effect on the lamp surface 41.

[0024] Among them, the telescopic rod 81 includes a first rod 82 fixedly installed on the top of the L-shaped plate 70, and a second rod 83 is slidably inserted inside the first rod 82. A spring 84 is provided between the inner wall end of the first rod 82 and the outer wall end of the second rod 83. Two sliding grooves are provided on the opposite surfaces of the inner wall of the first rod 82, and a slider 85 is provided on the outer wall of the second rod 83 to cooperate with the two sliding grooves. The second rod 83 is slidably installed inside the first rod 82 through the slider 85 and the sliding groove. A spring 84 is provided inside the telescopic rod 81 to connect the first rod 82 and the second rod 83, so that the scraper 80 can compress the telescopic rod 81, and then combined with the elastic force of the telescopic rod 81, it is conducive to driving the scraper 80 to fit closely on the surface of the lighting surface 41.

[0025] The length of the scraping strip 80 is greater than the diameter of the lighting surface 41 , ensuring that the scraping strip 80 can clean the lighting surface 41 in all directions.

[0026] Among them, when the electric cylinder 60 is extended to the longest distance, the height of the spray head 90 is higher than the highest point of the lighting surface 41, ensuring that the lighting surface 41 can be fully sprayed, resulting in an excellent cleaning effect.

[0027] When the electric cylinder 60 is extended to the shortest distance, the height of the scraper 80 is lower than the lowest point of the lighting surface 41, so that the scraper 80 and the spray head 90 are lowered to the lowest height, so that when cleaning is not required, the effect of the light projection of the lamp 40 is not affected.

[0028] Working principle: When in use, the cleaning liquid is sprayed onto the surface of the lighting surface 41 by setting the spray head 90, which is conducive to washing away large particles of dust and impurities on the lighting surface 41, and then the surface of the lighting surface 41 is scraped and cleaned by the scraper 80, which is conducive to scraping away the dust and cleaning liquid on the surface of the lighting surface 41 together. Therefore, there is no need to manually clean the decorative lamp, and the cleaning process is safe and convenient, so that the cleaning process of the lighting surface 41 on the decorative lamp is convenient and automated. When the scraper 80 contacts the lighting surface 41, the telescopic rod 81 is compressed by the scraper 80, and then combined with the elastic force of the telescopic rod 81, it is conducive to driving the scraper 80 to fit closely on the surface of the lighting surface 41, so that the scraper 80 has a better cleaning effect on the lighting surface 41.

[0029] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
