Liquid storage device for a rotary lance

The present invention provides a liquid storage device for a swirling spray gun, especially a liquid storage device that can supply different liquids to be sprayed outward from the spray gun, and is connected with a connecting pipe by a connecting sleeve of the spray gun, and then connected to the liquid storage by the connecting pipe. The system, and the liquid storage system has two or more liquid storage tanks, so as to provide different liquids for the spray gun for mixed spraying purposes.

According to the advancement of the technological era, people's quality in clothing, food, housing, transportation and entertainment has also been continuously improved. In terms of transportation, various vehicles such as steam and locomotives have become the means of transportation for people. It is also increasing with each day. Regarding the cleaning and finishing operations of various steam and locomotives, although the electric washing machine is available for automatic cleaning, after all, the electric washing machine rolls and scrubs on the outside of the vehicle body only by rolling the brush body. The edges or bumps are not fully cleaned, so many people will wash the car by hand washing, which can make the car body look more complete.

In the general cleaning work, the brush is washed with a water brush, cloth, etc., and the outside of the object is cleaned and washed. When cleaning in a vehicle or a building, a strong water column and brush are needed. The auxiliary cleaning operation such as cloth towel is carried out, and the water line is extended by the water pipe. The water pipe is flattened by the finger at the end of the water pipe, and the water supply column is sprayed in a strong manner, and the appearance of the object can be washed, and then flushed. Use a brush, cloth, etc. for cleaning The method of washing is not only time-consuming and labor-intensive, but also wastes a lot of water. It is quite inconsistent with the demand for water saving and energy saving. However, the traditional cleaning operation will cause a lot of water loss, and the waste of water resources is quite serious. In order to improve the waste of water caused by traditional cleaning operations, the use of high-pressure air combined with water guns can strengthen the power of water column scouring, and can also control the time of water consumption without causing the loss of a large number of water sources, such as certificate numbers. No. M296083, is a new patent case of "Air Compression Brush" issued on August 21, 1995. Application No. 095205213, please refer to Figure 8 for a description of the air pressure. The side view of the spray gun, the spray gun A is composed of a grip A1, a T-tube A2, a liquid cylinder A3 and a spray pipe B, and the spray pipe B includes a bell tube B1, and the bell tube B1 is provided at one end. The screw seat B11 is screwed to the pressure air outlet end A4 of the spray gun A, and the outer end of the bell tube B1 is open, and the thread at the center of the pressure air outlet end A4 of the spray gun A is the end of the return force tube C. Connector C1 screw The lock is fixed, and a weighted pipe C2 is disposed at an appropriate external position of the return force pipe C. Then, the spray gun A is input to the outside high pressure air from the grip A1, and then transmitted to the pressure air outlet end A4 via the T-shaped pipe A2, and the high-pressure air is And the water in the liquid cylinder A3 is taken out by the Venturi effect at the T-shaped tube A2, and after the pressurized air outlet end A4 is mixed with the high-pressure air, it is ejected outward through the returning force tube C to spray through the air pressure. The gun A performs the flushing operation; however, it is conventionally known that the spray gun A is only provided with a single liquid cylinder A3, and the cleaning liquid must be stored in the liquid cylinder A3 before the spray gun A performs the cleaning operation of the spray liquid. The liquid used can usually be a water, a cleaning agent or a liquid composed of a cleansing detergent. In the operation, the cleaning agent or the liquid cylinder A3 for mixing is sprayed to the spray gun A, and after being cleaned, Then change the liquid cylinder A3 of the water to spray the spray gun A to remove the original cleaning agent, which will cause the liquid cartridge A3 storing different liquids to be frequently replaced during the operation of the spray gun A, and must also be cleaned and cleaned. The operation of the agent and the clean water is not only time-consuming and labor-intensive. The liquid storage capacity of the single liquid cylinder A3 is quite limited, and must be supplemented frequently, which causes troubles in the operation of the spray gun A, and there are many inconveniences in actual operation and application.

Therefore, how to solve the current high-pressure air spray gun only supplies a single liquid through a single liquid barrel, and must frequently replace the missing and problem of different liquid barrel applications, and the internal capacity of the liquid barrel is limited, and the application must also frequently replenish the liquid. And troubles, that is, the direction that those who are engaged in this industry want to improve.
