Gun structure

The present invention relates to a spray gun structure, in particular to a rotary member disposed outside the second transfer tube for contacting the inner wall of the sleeve, and avoiding the blocks disposed outside the second transfer tube directly in the sleeve The structure of the lance that the walls rub against each other and is damaged.

The traditional cleaning device is mainly based on the manpower repeated pressing sprayer. The main principle is the principle of air atmospheric pressure. By pulling the rod in a pulling process, the water is sucked into the water spray pipe and then pushed by the thrust to make the water storage from the pipe. However, such early sprayers can only spray water once during the pressing process, and the frequent and laborious pressing times often bring a lot of inconvenience to the user.

For example, the Republic of China "No. M404735" patent discloses a slewing gun, which mainly discloses that the gun body is provided with a barrel and a liquid supply pipe, and an infusion line is provided in the infusion hole of the gun body, and the infusion line is disposed in the delivery line. The liquid tube is directly extended and bent to the outside of the infusion hole, and the external cleaning liquid is taken up by the infusion line, and then combined with the liquid of the liquid supply tube to be ejected.

In the above known prior art, a plurality of weights are provided outside the liquid supply pipe; however, when the liquid supply pipe rotates within the gun head, the weights will be in the metal inner tube of the inner wall of the gun head. Collision and friction occur, which causes the weight to break and break under high speed and long time collision and friction. Once the weight is damaged and broken, the new liquid supply pipe must be updated to make the user need the consumables. Increased costs.

In addition, as disclosed in the Patent No. M417190 of the Republic of China, a gas-liquid rotary injection device mainly discloses a gas flow pipe, a spoiler pipe and a liquid flow pipe, and the gas flow pipe is connected Connected to the spoiler tube, the liquid flow tube is inserted into the spoiler tube and directly extended and bent to the outside of the gas flow tube. A high flow rate gas is ejected from the gas flow tube to the spoiler tube, and a liquid is caused by the high flow rate gas. After the pressure difference is sucked by the liquid flow tube, the high-flow gas is mixed with the liquid and ejected.

In the above-disclosed prior art, a load ring is disposed outside the spoiler; however, when the spoiler rotates within the nozzle cover, the load ring may collide and rub against the inner wall of the nozzle cover. As a result, the load ring is likely to cause damage and breakage under high speed and long-term collision and friction. Once the load ring is damaged and fractured, the new spoiler must be updated, which causes the user to increase the cost of the consumables.

In order to solve the problems caused by the prior art, the present invention proposes a spray gun structure comprising a spray gun body, a spray gun handle, a sleeve, and a second transfer tube. The spray gun body has a first connection port at one end and a second connection port at the other end; the spray gun handle is connected to the first connection port of the spray gun body; the sleeve is sleeved on the second connection port of the spray gun body The second conveying pipe is connected to the second connecting port of the spray gun body and is bored, and the second conveying pipe is in communication with the spray gun body; wherein the second conveying pipe is provided with a plurality of blocks and at least one rotation The rotating member rotates with the second conveying pipe as an axis, and the diameter of the rotating member is larger than the diameter of the blocks. The high pressure gas can be connected to the outside by the handle of the spray gun, and then sent out by the second transfer pipe through the spray gun body. When the second transfer pipe is driven by the high pressure gas to rotate inside the sleeve, the rotating part with larger diameter can be connected with the inside of the sleeve. The walls form a contact to prevent the blocks from colliding with the inner wall of the sleeve and rubbing and damaging.
