The utility model discloses a kind of spray gun, which includes the main body of the spray gun, the lower end of which is provided with a capacitive groove, and the interior is provided with a capacitive cavity connected with the storage tank, and the seal part is built in the tank, and the inside is formed with a through groove, and the through groove is connected with the sealing groove connected to the sealing groove and connected with the seal groove. The nozzle is connected with the nozzle and the nozzle is connected to the lower end of the main body of the spray gun and the upper end of the nozzle is extended up to form a seal convex, and the outer wall of the sealed protruding is compacted to the side wall of the sealing groove. The utility model sets a holding slot at the lower end of the main body of the spray gun, and sets a seal part placed in the sealing groove. The lower end of the sealing part sets the sealing groove which is gradually reduced in the cross section street. The sealing part is sealed between the nozzle and the sealing part through the outer wall of the seal protruding on the nozzle, and the sealing part is under the pressure of the sealing protruding. The outer wall is tightly attached to the inner wall of the holding groove, thereby realizing the seal between the sealing part and the main body of the spray gun, and has simple structure and good sealing performance.
【技术实现步骤摘要】
一种喷枪
本技术涉及喷码技术,尤其是涉及一种喷枪。
技术介绍
目前,进行油墨喷印时,一般在喷枪内设置晶体振荡模块,其可将油墨调制成墨点并由喷枪的喷嘴内喷出。在喷印完成后,一般需要将喷嘴口密封,以避免油墨干固于喷嘴口及喷嘴口的油墨吸附空气中的灰尘而导致喷嘴口被污染或堵塞。但是,现有的喷嘴与喷枪主体的连接密封性较差,即使将喷嘴口密封,其内依然油墨依然干固,其不利于下一次喷印。
技术实现思路
本技术的目的在于克服上述技术不足,提出一种喷枪,解决现有技术中喷枪的喷嘴与其主体连接密封性差的技术问题。为达到上述技术目的,本技术的技术方案提供一种喷枪,包括:一喷枪主体,其下端面设置有一容置槽,且其内部设置有一与所述容置槽底部连通的容置腔;一密封部,其配合内置于所述容置槽,且其内形成有上下贯通的通槽,所述通槽包括一由密封部下端面向上延伸形成的横截面积逐渐减小的密封槽及一与密封槽连通的连接槽;及一喷嘴,所述喷嘴连接于所述喷枪主体下端且其上端向上延伸形成一呈环状的密封凸起,所述密封凸起的外壁配合抵紧于所述密封槽侧壁。与现有技术相比,本技术在喷枪主体下端设置一容置槽,并设置一内置于密封槽的密封部,密封部下端设置横截面街逐渐减小的密封槽,其通过喷嘴上的密封凸起外壁抵压密封槽侧壁使喷嘴与密封部之间密封,同时密封部在密封凸起抵压下其外壁抵紧于容置槽内壁,从而实现密封部与喷枪主体之间的密封,其结构简单、密封性好。附图说明图1是本技术的喷枪的连接结构示意图;图2是本技术的喷枪的分解结构示意图;图3是本技术的图2的A-A向剖视图。具体实施方式为了使本技术的目的、技术方案及优点更加清楚明白,以下结合 ...
