Description

Technical Field

[0001] The present invention relates to the technical field of spray guns, and particularly to a two-way spray hand-held buckle spray gun that can spray liquid with the product inverted. Background Art

[0002] At present, spray guns are widely used in various fields of life. For example, they can be used on watering sprayers and oil sprayers in the kitchen. Usually, the pump nozzle is detachably installed on a bottle, can, or pot. The basic principle of the pump nozzles on the market currently is to use a piston to move in the pump body, causing the gas in the pump body to flow, the pressure to become smaller, the pressure outside the pump body to remain unchanged, generating a pressure difference between the inside and outside of the pump body, and guiding the liquid out of the pump body through the pressure difference.

[0003] However, existing spray guns all suck liquid through a straw. When spraying liquid in the forward direction, the liquid can be basically sprayed out cleanly through the straw. The main problem is that when spraying in the inverted state, the liquid cannot be sprayed out cleanly. The present invention can well solve the problem of spraying the liquid cleanly when inverted.

[0004] Therefore, it is very necessary to invent a two-way spray hand-held buckle spray gun that can spray liquid with the product inverted to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a two-way spray hand-held buckle spray gun that can spray liquid with the product inverted to solve the problems raised in the above background art.

[0006] To achieve the above purpose, the present invention provides the following technical solution: A two-way spray hand-held buckle spray gun that can spray liquid with the product inverted, including a gun body assembly, and a large ring is snap-fitted and sleeved at the bottom end of the gun body assembly;

[0007] The gun body assembly includes a gun body. A connecting cover is integrally formed at the bottom end of the gun body. A liquid outlet and a piston chamber are integrally formed at the top and bottom ends of one side of the gun body respectively. An inverted section assembly is fixedly installed inside the connecting cover. A liquid inlet communicating with the liquid outlet channel is opened at one side of the bottom end of the gun body, and a resilient valve assembly is movably arranged at the upper end inside the liquid inlet. An exhaust port is integrally formed at one side inside the connecting cover;

[0008] The inverted section assembly includes an inverted section body. One side of the top end of the inverted section body is integrally formed with a liquid outlet pipe. One side of the bottom end of the inverted section body near the liquid outlet pipe is integrally formed with a liquid inlet pipe. An inlet liquid groove communicating with both the liquid outlet pipe and the liquid inlet pipe is formed inside the inverted section body. A transverse inlet liquid groove is formed through the inner wall on one side of the inlet liquid groove. A side seal cover is movably arranged at the opening at the end of the transverse inlet liquid groove far from the inlet liquid groove. An inverted inlet liquid port is formed through the top inner wall of the transverse inlet liquid groove. An inverted ball valve is movably arranged inside the inverted inlet liquid port. An inverted inlet liquid groove is integrally formed at the bottom end of the inverted section body. An exhaust notch is integrally formed at the edge of one side of the bottom end of the inverted section body near the liquid inlet pipe. The bottom end of the liquid inlet pipe is inserted with a suction pipe;

[0009] The elastic valve assembly includes a ring. A sealing spherical surface is arranged at the bottom of the ring. A plurality of elastic ribs distributed in a circular array are integrally formed at the bottom end of the ring. The bottom ends of the elastic ribs are integrally formed with the top edge of the sealing spherical surface.

[0010] Preferably, the bottom end of the sealing spherical surface is circular and is adapted to the top opening of the liquid outlet pipe. The middle part of the elastic rib is bent outward. The top end of the ring is attached and connected to the inner wall of the top end of the inlet liquid port.

[0011] Preferably, a clamping groove is integrally formed on the other side of the gun body. A buckle ring is integrally formed around the middle part of the outer side wall of the connecting cover. The buckle ring is adapted to the large ring.

[0012] Preferably, a drainage valve and a water distributor adapted to each other are installed inside the liquid outlet. The drainage valve is located at one end close to the liquid outlet channel. A head cap is installed at the opening of the liquid outlet.

[0013] Preferably, an outer cover is snap-connected to the side of the gun body close to the clamping groove. A piston is movably arranged inside the piston cavity. One end of the piston is fixedly installed with a piston sleeve rod.

[0014] Preferably, a handle assembly is arranged on the side of the gun body assembly far from the outer cover. An external spring assembly is arranged between the handle assembly and the gun body assembly.

[0015] Preferably, the handle assembly includes a wrench body. Slots are integrally formed on both sides of the top end of the back of the wrench body. An activity groove is integrally formed in the middle of the back of the wrench body. The activity groove is adapted to the piston sleeve rod.

[0017] Technical effects and advantages of the present invention:

[0018] 1. Through the setting of the inverted section assembly in the present invention, when spraying liquid forward, the inverted ball valve blocks the inverted liquid inlet. The liquid in the bottle enters the inside of the piston chamber through the straw, liquid inlet pipe, liquid inlet groove and liquid outlet pipe, and then is sprayed out through the liquid outlet channel. When inverted, the straw cannot intake liquid, while the inverted ball valve opens the inverted liquid inlet. The liquid in the bottle enters the inside of the inverted liquid inlet through the inverted liquid inlet groove. Finally, when pressing the handle assembly, the liquid enters the liquid inlet groove through the inverted liquid inlet and the side sealing cover, forming the effect of spraying liquid forward. Thus, it can spray liquid forward and inverted, enabling the product in the bottle to be completely sprayed without waste.

[0019] 2. By using the elastic valve assembly to replace the traditional ball valve in the present invention, the problem that the ball valve leaves the sealing position due to gravity during inversion and the inverted spraying effect is poor is improved. At the same time, through the setting of the exhaust gap, the exhaust gap is communicated with the exhaust port, which can make the exhaust smoother and improve the spraying effect.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] The present invention provides a Figures 1-7 bidirectional spray hand-held trigger gun that can spray liquid in an inverted manner as shown, including a gun body assembly 1, and a large ring 3 is snap-fitted and sleeved at the bottom end of the gun body assembly 1.

[0030] Further, the gun body assembly 1 includes a gun body 101. At the bottom end of the gun body 101, a connecting cover 102 is integrally formed. At the top and bottom ends of one side of the gun body 101, a liquid outlet 105 and a piston chamber 103 are integrally formed respectively. Inside the connecting cover 102, an inverted joint assembly 2 is fixedly installed. At one side of the bottom end of the gun body 101, a liquid inlet 106 communicating with the liquid outlet channel 104 is provided. And at the upper end inside the liquid inlet 106, a spring valve assembly 13 is movably arranged. On one side inside the connecting cover 102, an exhaust port 107 is integrally formed. On the other side of the gun body 101, a clamping groove 108 is integrally formed. In the middle of the outer side wall of the connecting cover 102, a snap ring 109 is integrally formed around it. And the snap ring 109 is adapted to the large ring 3. The setting of the snap ring 109 can prevent the large ring 3 from moving up and down. At the top of the connecting cover 102, a cylindrical groove is provided at the top of the inverted liquid inlet 205, which has a limiting effect on the inverted ball valve 208 to prevent the inverted ball valve 208 from slipping out. Inside the liquid outlet 105, a drainage valve 8 and a water distributor 9 which are adapted to each other are installed. And the drainage valve 8 is located at one end close to the liquid outlet channel 104. At the opening of the liquid outlet 105, a head cap 10 is installed. On one side of the gun body 101 close to the clamping groove 108, an outer cover 11 is connected by a buckle. Inside the piston chamber 103, a piston 4 is movably arranged. At one end of the piston 4, a piston sleeve rod 5 is fixedly installed. On one side of the gun body assembly 1 away from the outer cover 11, a handle assembly 6 is provided. An external spring assembly 7 is arranged between the handle assembly 6 and the gun body assembly 1.

[0031] The inverted section assembly 2 includes an inverted section main body 201. One side of the top end of the inverted section main body 201 is integrally formed with a liquid outlet pipe 202. One side of the bottom end of the inverted section main body 201 near the liquid outlet pipe 202 is integrally formed with a liquid inlet pipe 203. An inlet liquid groove 204 communicating with both the liquid outlet pipe 202 and the liquid inlet pipe 203 is formed inside the inverted section main body 201. A transverse inlet liquid groove 206 is formed through the inner wall on one side of the inlet liquid groove 204. And a side seal cover 207 is provided at the opening at one end of the transverse inlet liquid groove 206 away from the inlet liquid groove 204. After the side seal cover 207 is installed, it is not movable. The side seal cover 207 can seal one end of the transverse inlet liquid groove 206 to prevent liquid from leaking. An inverted inlet liquid port 205 is formed through the top inner wall of the transverse inlet liquid groove 206. An inverted ball valve 208 is movably arranged inside the inverted inlet liquid port 205. An inverted inlet liquid groove 209 is integrally formed at the bottom end of the inverted section main body 201. An exhaust notch 210 is integrally formed at the edge of one side of the bottom end of the inverted section main body 201 near the liquid inlet pipe 203. Through the setting of the exhaust notch 210, the exhaust notch 210 communicates with the exhaust port 107, which can make the exhaust smoother and improve the liquid spraying effect. The bottom end of the liquid inlet pipe 203 is inserted with a suction pipe 12. Through the setting of the inverted section assembly 2, when spraying liquid forward, the inverted ball valve 208 blocks the inverted inlet liquid port 205. The liquid in the bottle enters the inside of the piston chamber 103 through the suction pipe 12, the liquid inlet pipe 203, the inlet liquid groove 204 and the liquid outlet pipe 202, and then is sprayed out through the liquid outlet channel 104. When inverted, the suction pipe 12 cannot intake liquid, while the inverted ball valve 208 opens the inverted inlet liquid port 205. The liquid in the bottle enters the inside of the inverted inlet liquid port 205 through the inverted inlet liquid groove 209. Finally, when pressing the handle assembly 6, the liquid enters the inlet liquid groove 204 through the inverted inlet liquid port 205 and the side seal cover 207, forming the effect of spraying liquid forward. Thus, it can spray liquid forward and inverted, and can spray out all the products in the bottle without waste.

[0032] The elastic valve assembly 13 includes a ring 1301. A sealing spherical surface 1302 is arranged at the bottom of the ring 1301. A plurality of elastic ribs 1303 distributed in a circular array are integrally formed at the bottom end of the ring 1301. And the bottom ends of the elastic ribs 1303 are integrally formed with the top edge of the large end of the sealing spherical surface 1302. The bottom end of the sealing spherical surface 1302 is circularly arranged and is adapted to the top opening of the liquid outlet pipe 202. The middle part of the elastic rib 1303 is bent outward. The top end of the ring 1301 is attached and connected to the inner wall of the top end of the inlet liquid port 106. By using the elastic valve assembly 13 to replace the traditional ball valve, the problem that the ball valve leaves the sealing position due to gravity when the product is inverted and the inverted liquid spraying effect is poor is improved.

[0033] Secondly, the handle assembly 6 includes a wrench body 601. On both sides of the top end of the back surface of the wrench body 601, slots 602 are integrally formed. In the middle of the back surface of the wrench body 601, a movable slot 603 is integrally formed, and the movable slot 603 is adapted to the piston sleeve rod 5. The external spring assembly 7 includes a clamping block 701. At both ends of the top of the clamping block 701, arc-shaped elastic handles 702 are integrally formed, and the ends of the arc-shaped elastic handles 702 away from the clamping block 701 are adapted to the slots 602. The clamping block 701 is adapted to the clamping slot 108.

[0034] Working principle of the present invention:

[0035] During use, the piston 4 is operated by pressing the handle assembly 6 by hand, so that the piston 4 moves in the piston chamber 103, causing the gas in the gun body assembly 1 to flow, and the pressure becomes smaller. The pressure outside the gun body assembly 1 remains unchanged, creating a pressure difference inside and outside the gun body assembly 1. The liquid is sucked in from the straw 12, causing the sealing spherical surface 1302 to jump upward, and the liquid is sucked into the piston chamber 103. Then, the wrench is squeezed again. After the liquid is sucked, the elastic rib 1303 will immediately recover its deformation, and the sealing spherical surface 1302 rebounds to the sealing surface, preventing the sucked liquid from flowing back into the bottle. When the wrench is squeezed, the piston 4 moves downward to form a pressure difference. When the liquid is discharged from the liquid outlet, a high-speed air flow will be instantly formed, atomizing the liquid and discharging it from the product interior.

[0036] When used in an inverted spraying manner, the product is inverted, and the liquid naturally flows into the interior from the inverted liquid inlet groove 209. The inverted ball valve 208 leaves the sealing surface due to gravity, squeezing the handle assembly 6 to form an air pressure difference. The liquid enters from the inverted liquid inlet 205 on the inverted joint assembly 2, flows into the liquid inlet groove 204 through the transverse liquid inlet groove 206, and enters the piston chamber 103. Then, the liquid is ejected in the same way as in the forward spraying.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
