[0010] Preferably, the method for using the ceramic tile safety sandblasting equipment comprises the following steps:

[0011] S1: When the device is in use, first fill the inside of the loading barrel with the mixed mortar, and then press the spraying device to control the mortar inside the loading barrel to spray to the designated area. Each time the device is pressed, the protection end of the nozzle safety protection device is driven to expand to both sides of the spray head, thereby protecting both sides of the spray head;

[0012] S2: Every time the pressing end of the press spraying device is released, the spray head safety protection device automatically closes the spray head, so as to protect the spray head from contamination when sandblasting is not required, and at the same time, the mortar adhering to the spray head is scraped and cleaned;

[0013] S3: While spraying the mortar, each press drives the synchronous cleaning device to work, and then the synchronous cleaning device drives the jet cleaning ring to descend synchronously with the decrease of the mortar liquid level inside the charging barrel. While descending, the mortar adhered to the inner wall of the charging barrel is scraped off, and the downward airflow generated inside the jet cleaning ring blows the mortar adhered to the inner wall of the charging barrel.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, firstly, the mortar for tile sandblasting is filled into the loading barrel, and by pulling the pressing ring, the driving block is deflected under the action of the elastic rope, the first connecting member and the second connecting member, and the piston rod and the piston block are driven to slide into the piston tube. While sliding, an airflow toward the outside of the injection tube is generated to squeeze the mortar in the gas flow chamber out through the injection head, thereby completing the mortar injection. The pressing ring is released, and the piston block is reset under the action of the spring to generate a reverse flow of air, thereby extracting a part of the mortar in the loading barrel into the gas flow chamber, so as to facilitate the next mortar injection operation.

[0016] In the present invention, when the pressing pull ring is pulled to drive the driving block to deflect for mortar injection, the rotation of the pressing pull ring drives the first bevel gear and the second bevel gear to rotate, thereby driving the first gear to rotate, thereby driving the sliding tooth groove block to move on the driving slide in the direction away from the injection head, thereby exposing the injection head, and when the deflection plate moves to the second gear at the bottom and contacts with the first tooth groove rod, the deflection plate, the flexible protective sleeve and the protective cover are driven to deflect in the direction away from the injection head synchronously, and the trigger rod is contacted with the trigger member and squeezed to drive the protective cover to rotate toward the inside of the flexible protective sleeve, the flexible protective sleeve is squeezed and gradually becomes a straight state, and the folding rod is folded accordingly. At this time, the two flexible protective sleeves are respectively It is located on both sides of the injection head and is inclined, thereby protecting the area where mortar is sprayed, preventing natural wind on both sides of the injection head from interfering with the injection of mortar, protecting on-site personnel while ensuring that the mortar is sprayed more evenly. When the push-pull ring is released, the drive block deflects in the opposite direction and drives the two flexible protective sleeves to automatically reset, and the protective cover is reset accordingly, so that the two flexible protective sleeves and the protective cover completely cover the injection head. While covering, the protective cover contacts the end of the injection head to scrape off the mortar adhered to its surface, thereby protecting the injection head from contamination when sandblasting is not required, and at the same time achieving the effect of scraping off and cleaning the mortar adhered to the injection head.

[0017] In the present invention, when the pressing pull ring is pulled, a part of the airflow generated inside the piston tube enters the driving box and the jet cleaning ring respectively through the first air supply pipe and the second air supply pipe, and the airflow entering the driving box drives the driving fan blade to rotate a certain angle, and under the transmission of the third gear and the fourth gear, drives the second toothed rod to drop a certain distance, and then drives the jet cleaning ring to drop a certain distance inside the charging barrel under the cooperation of the first magnet and the second magnet, and then cooperates with the lowering of the mortar liquid level inside the charging barrel to drop accordingly. The descent of the jet cleaning ring can scrape off the mortar adhered to the inner wall of the charging barrel and drip into the mortar inside the charging barrel, thereby avoiding waste of mortar and realizing automatic cleaning of the inner wall of the charging barrel, and through the second air supply pipe and the jet pipe at the bottom of the jet cleaning ring, the mortar adhered to the inner wall of the charging barrel can be blown, further improving the cleaning efficiency of the inner wall of the charging barrel, thereby improving the utilization rate of the mortar inside the charging barrel. After the sandblasting is completed, the jet cleaning ring can be directly pulled upwards through the second air supply pipe to be reset. BRIEF DESCRIPTION OF THE DRAWINGS
