200422105 发明 Description of the invention: [Technical field to which the invention belongs] The present invention relates to the improvement of a liquid spraying device such as a spray gun " II = The present system is about the spray gun and the liquid to be sprayed. 々Bedding connection. Taisu Day 4 Masters

The present invention is particularly applicable to a mouth nozzle capable of detachably mounting the reservoir C to the spray gun. Releasable connection and enough shoulders [Previous technology] Spray gun has been widely used for car body repairing tanks, which need to be repaired when the accident vehicle is painted. In the known spraying and scavenging known as shi shi shi shi + + 隹 隹, the liquid system is stored in the report σσ and the liquid will be fed from there to a nozzle. § When the nozzle is exposed, the liquid will be atomized, and will form a spray. The liquid can be fed to the reservoir by gravity or suction, but more recently, it has been fed to the reservoir by means of a self-contracting air line to the reservoir. Traditionally, the liquid supply system is housed in a complementary part of the tank and the spray gun ', and the tank is engaged by calling the supplementary thread, so it must be worn on the visit. . In this way, the can can be removed for cleaning, ... the can is fastened to it when it empties. / 、 In the ground, the cover can be removed by # X ㈣❹ # —removable sister piece to attach the can to the spray gun, and add the body to the can. Apricot 6 inches, when the liquid 4 + Tian 70 is sprayed, the cans can be removed. The day, the master * the rush and the cans can be reused. When using this configuration, “the spray gun will attempt to tighten a thread with an unmatched thread ...”, it may be damaged by Ω · \ 88 \ 889Ι4 ΠΟΓ due to, for example, incorrect use of the tank material. Also, when spraying is completed, you need to clean it carefully, and remove all traces of liquid from the thread to prevent the thread from being blocked, such as dried paint, and prevent it from being sprayed later. The liquid was contaminated. Damaged or blocked posts may make reading unusable, and you need to buy a new congratulatory rush, which will increase your income,

And if time is wasted because there is no spare spray to grab the succession spray, it will be more inconvenient.…,………,…, Inconvenience. In addition, when cleaning threads, ~~ agent can also be used to clean the spray gun and can In terms of health and safety considerations, the use of solvents is not desired, and the disposal of solvents after use will also cause problems. Recently, a system has been developed, A 4 + # where the reservoir can be used after treatment to reduce waste. The amount of cleaning required. With this system, the reservoir can be filled with the liquid to be sprayed before being attached to the spray gun. Traditional screw-type connections require rotating the reservoir several times, which is typically For a minimum of four or five turns, tighten the receptacle with π full-mesh threads and a fluid tight seal. This will take a while, and the user will need to be quite careful and skilled to prevent the liquid from spilling out when the receptacle is full. In order to reduce these problems, a system has been proposed to connect the storage benefit to the spray gun by an adapter 'where the adapter is threaded into the spray gun and the receptacle is provided-may Quick release snap-on connection. # 如 ， The outer device and the adapter can be provided with a latch-type structural member, which can be engaged by “pushing, twisting, and twisting”, and by this action, the container only needs to rotate less than one full turn to A receptacle is connected to the spray grab. ≫ This configuration will allow a simple and efficient way to attach and detach the receptacle to the mouth grab, which will reduce splashing when the receptacle holds liquid. \ 88 \ 88gu nnr. 200422105, and requires only a low level of proficiency on the part of the user. Providing this adapter will allow existing spray guns with a threaded connection to be used in conjunction with a conventional rigid can It can be used in combination with this system that uses a treatable bedding benefit. This will provide users with the advantage of reducing the amount of cleaning required when the spray is completed. However, if the hand f is not ready If there is an adapter with a thread that can cooperate with the thread on the spray gun, that is, if the adapter is removed for cleaning and lost, the question will occur. The spray gun will therefore not be able to be combined with the processable Container use: and remote-user does not have-spare adapter, or When the rigid lock can be screwed to one of the spray cans without the adapter, the working time will be wasted. Also, the threaded connection between the spray grab and the adapter is like the spray grab and the can. The connection between them is generally easy to cause damage due to incorrect use, making the spray gun unusable. 'Summary of the Invention' ^ Considers the aforementioned problems encountered by existing methods for fastening the -reservoir to the spray gun.
