[0002] The all-plastic spray square gun uses environmentally friendly recyclable materials and is reusable. Its main material is PP. The all-plastic design makes the product highly compatible. There are a variety of large circle specifications and nozzles to choose from. At the same time, the spray square gun, as a simple and effective liquid atomization equipment, is widely used in household chemical cleaners, automotive protective products, gardening products, animal care products and home polishing products. It brings a lot of convenience and speed to people. Its principle is to increase the pressure of the spray pot through the reciprocating motion of the trigger to spray out the liquid in the pot. However, the spring is in direct contact with water during the reciprocating process, and the spring soaked in water for a long time is more susceptible to corrosion, which reduces the strength and durability of the spring, easily leads to breakage, and is not resistant to high pressure, which directly affects the service life of the square gun.

The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0025] For examples, see Figure 1-6 The utility model provides a technical solution:

[0026] A high-performance high-pressure resistant square gun comprises a gun shell 1 and a main gun body 2. The gun shell 1 is clamped on the outer surface of the main gun body 2.

[0027] The main gun body 2 includes a pump body 21, a spring 22, a trigger 23, an internal thread seat 24 and an elongated pressure seat 25. The pump body 21 includes a transmission seat 211. An elongated pressure cylinder 212 is fixedly installed at the center of the top surface of the transmission seat 211. The spring 22 and the elongated pressure seat 25 are located inside the elongated pressure cylinder 212. A pressure piece 231 is fixedly installed on the top surface of the trigger 23 near one end of the movable notch 2113. The top of the pressure piece 231 extends through the bottom surface of the elongated pressure cylinder 212. To both sides of the bottom of the elongated pressing seat 25, a water spray pipe 213 is installed through the outer surface of the elongated pressing cylinder 212 near the bottom end, and a nozzle 214 is fixedly installed on the end of the water spray pipe 213 away from the elongated pressing cylinder 212. A water outlet 251 is provided at the bottom end of the elongated pressing seat 25 near the water spray pipe 213, and a spring groove 252 is provided at the center of the top surface of the elongated pressing seat 25. A suction pipe 253 is installed through the bottom end of the elongated pressing seat 25, and the outer surface of the suction pipe 253 is fixedly installed. A limit seat 254 is mounted near the inner thread seat 24. When in use, the trigger 23 is pulled. At this time, under the action of the trigger 23, the pressure piece 231 pushes the elongated pressure seat 25 upward. At the same time, under the pressure of the elongated pressure seat 25, the spring 22 contracts, and the elongated pressure seat 25 rises accordingly. The water outlet 251 is connected to the water spray pipe 213. At the same time, the elongated pressure cylinder 212 is in a negative pressure state. The water is sucked out by the suction pipe 253, and passes through the elongated pressure seat 25, the outlet pipe 213, and the elongated pressure cylinder 212 in turn. The water hole 251, the water spray pipe 213, and finally the nozzle 214 sprays, and then the elongated pressure seat 25 is reset under the reaction of the spring 22, and the flow channel is closed, and the existing square gun structure is improved as a whole. The elongated pressure cylinder 212 and the elongated pressure seat 25 can prevent the spring 22 from being soaked in water for a long time during the reciprocating motion, greatly slowing down the decline in the strength and durability of the spring 22, high performance, preventing breakage, and high pressure resistance, thereby extending the service life of the square gun;

[0028] In this embodiment, please refer to Figure 3 and Figure 4 The top and bottom ends of the spring 22 are in close contact with the inner top surface of the elongated pressing cylinder 212 and the inner bottom surface of the spring groove 252, respectively. The spring groove 252 is provided to facilitate the stability and reliability of the reciprocating operation;

[0029] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The upper and lower sides of the water spray pipe 213 are fixedly installed with mounting brackets 2131, and the end of the nozzle 214 away from the water spray pipe 213 is clamped with a square shell 2141 with a spray hole, and the mounting bracket 2131 is provided to facilitate the stability of the gun housing 1 after installation. At the same time, the plastic spring inside the nozzle 214 is positioned by the spray hole square shell 2141. When spraying water, the plastic spring pops out of the water outlet under the action of negative pressure, which is convenient for water discharge. Conversely, it can be closed under the reaction.

[0030] In this embodiment, please refer to Figure 1 , Figure 2 and Figure 3 The bottom end of the transmission seat 211 is clamped with an internal thread seat 24 through a plurality of groups of annularly distributed clamping seats 2111. A locking seat 2112 adapted to the trigger 23 is fixedly installed on one side of the outer surface of the transmission seat 211 near the bottom of the water spray pipe 213. The trigger 23 and the locking seat 2112 are movably connected through a locking rod 232. Both ends of the outer surface of the transmission seat 211 near the locking seat 2112 are provided with movable notches 2113. The internal thread seat 24 can be quickly disassembled and assembled through the provided clamping seat 2111. At the same time, the trigger 23 can be positioned and prevented from disengaging during the reciprocating operation through the provided locking seat 2112 and the locking rod 232. At the same time, the provided movable notch 2113 facilitates the movement of the trigger 23.

[0031] Working principle: When in use, pull the trigger 23. At this time, under the action of the trigger 23, the pressure piece 231 pushes the elongated pressure seat 25 upward. At the same time, under the pressure of the elongated pressure seat 25, the spring 22 contracts, and the elongated pressure seat 25 rises accordingly. The water outlet 251 is connected with the water spray pipe 213. At the same time, the elongated pressure cylinder 212 is in a negative pressure state. The water is sucked out by the suction pipe 253, and passes through the elongated pressure seat 25, the water outlet 251, and the water spray pipe 213 in turn, and is finally sprayed by the nozzle 214. Subsequently, the elongated pressure seat 25 is reset under the reaction of the spring 22, and the flow channel is closed. The overall square gun has a longer service life than the traditional square gun and has a certain promotion value.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
