A two-way, hand-operated spray gun that can spray liquid while the product is inverted.

Abstract

This utility model discloses a two-way spray gun with a handle that allows for spraying liquid from an inverted product. It relates to the field of spray gun technology and includes a gun body assembly with a large ring at the bottom end of the assembly. Through the inverted assembly, when spraying liquid in the forward direction, the inverted ball valve blocks the inverted inlet, allowing liquid from the bottle to enter the piston chamber through the suction tube, inlet pipe, inlet groove, and outlet pipe, and then spray out through the outlet channel. When inverted, the suction tube cannot enter liquid, but the inverted ball valve opens the inverted inlet, allowing liquid from the bottle to enter through the inverted inlet groove. Finally, pressing the handle assembly allows liquid to enter the inlet groove through the inverted inlet and side seal, creating a forward spraying effect. This allows for both forward and inverted spraying, ensuring that all product in the bottle is sprayed out without waste.

Description

Technical Field

[0001] This utility model relates to the field of spray gun technology, and in particular to a bidirectional spray gun with a handle that can spray liquid onto a product while it is upside down. Background Technology

[0002] Currently, spray guns are widely used in various aspects of life, such as on watering cans and kitchen oil sprayers. Pump nozzles are typically detachably mounted on bottles, cans, or jugs. The basic principle of most pump nozzles on the market is to use a piston moving within a pump body, causing gas to flow and decrease in pressure within the pump body, while the pressure outside the pump body remains constant. This pressure difference creates a pressure difference between the inside and outside of the pump body, which then guides the liquid out of the pump body.

[0003] However, existing spray guns all use a suction tube to draw liquid. When spraying liquid forward, the liquid can be sprayed cleanly by drawing liquid through the suction tube. The main problem is that when spraying upside down, the liquid cannot be sprayed cleanly. This utility model can effectively solve the problem of being able to spray liquid cleanly when upside down.

[0004] Therefore, it is necessary to invent a two-way spray gun with a handle that can spray liquid while the product is upside down to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a two-way spray gun with a handle that can spray liquid onto an inverted product, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a two-way spray gun with a handle that can spray liquid onto an inverted product, comprising a gun body assembly, wherein a large ring is snap-fitted and installed at the bottom end of the gun body assembly;

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

[0008] The inverted section assembly includes an inverted section body. An outlet pipe is integrally formed on one side of the top of the inverted section body. An inlet pipe is integrally formed on the bottom side of the inverted section body near the outlet pipe. An inlet groove communicating with both the outlet and inlet pipes is formed inside the inverted section body. A transverse inlet groove is formed through one inner wall of the inlet groove, and a side seal is movably provided at the opening of the transverse inlet groove away from the inlet groove. An inverted inlet port is formed through the top inner wall of the transverse inlet groove, and an inverted ball valve is movably provided inside the inverted inlet port. An inverted inlet groove is integrally formed at the bottom of the inverted section body. An vent is integrally formed on the edge of the bottom of the inverted section body near the inlet pipe. A suction tube is inserted into the bottom of the inlet pipe.

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

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

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

[0012] Preferably, the outlet is internally equipped with a matching diversion valve and a water divider, with the diversion valve located at one end near the outlet channel, and a cap installed at the opening of the outlet.

[0013] Preferably, the gun body is snap-fitted with an outer cover on the side near the slot, a piston is movably disposed inside the piston chamber, and a piston rod is fixedly installed at one end of the piston.

[0014] Preferably, a handle assembly is provided on the side of the gun body assembly away from the outer cover, and an external spring assembly is provided between the handle assembly and the gun body assembly.

[0015] Preferably, the handle assembly includes a wrench body, with slots integrally formed on both sides of the top back of the wrench body, and a movable groove integrally formed in the middle of the back of the wrench body, the movable groove being adapted to the piston rod.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] 1. This utility model, through the setting of the inverted assembly, allows for forward spraying. When spraying liquid in the forward direction, the inverted ball valve blocks the inverted inlet, and the liquid in the bottle enters the piston chamber through the straw, inlet pipe, inlet groove, and outlet pipe, and then sprays out through the outlet channel. When inverted, the straw cannot enter liquid, but the inverted ball valve opens the inverted inlet, and the liquid in the bottle enters the inverted inlet through the inverted inlet groove. Finally, when the handle assembly is pressed, the liquid enters the inlet groove through the inverted inlet and side seal, forming a forward spraying effect. This allows for both forward and inverted spraying, ensuring that the product in the bottle is completely sprayed without waste.

[0019] 2. This utility model replaces the traditional ball valve with a spring valve assembly, which improves the problem that the ball valve leaves the sealing position due to gravity when the product is inverted, resulting in poor spraying effect when inverted; at the same time, the setting of the venting notch and the connection between the venting notch and the venting port can make the venting smoother and improve the spraying effect.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] This utility model provides, for example Figure 1-7 The illustrated two-way spray gun with a handle allows the product to be sprayed while inverted. It includes a gun body assembly 1, with a large ring 3 attached to the bottom of the gun body assembly 1 via a snap-fit ​​connection.

[0030] Furthermore, the gun assembly 1 includes a gun body 101. A connecting cover 102 is integrally formed at the bottom end of the gun body 101. A liquid outlet 105 and a piston chamber 103 are integrally formed at the top and bottom ends of one side of the gun body 101, respectively. An inverted section assembly 2 is fixedly installed inside the connecting cover 102. A liquid inlet 106 communicating with a liquid outlet channel 104 is opened on one side of the bottom end of the gun body 101, and a spring valve assembly 13 is movably installed at the upper end of the liquid inlet 106. An exhaust port 107 is integrally formed on one side of the inside of the connecting cover 102. A slot 108 is integrally formed on the other side of the gun body 101. A retaining ring 109 is integrally formed around the middle of the outer wall of the connecting cover 102, and the retaining ring 109 is compatible with the large ring 3. The design of the retaining ring 109... The device prevents the large ring 3 from moving up and down. The top of the connecting cover 102 is provided with a cylindrical groove at the top of the inverted liquid inlet 205, which has a limiting effect on the inverted ball valve 208 and prevents the inverted ball valve 208 from sliding out. The liquid outlet 105 is equipped with a matching diversion valve 8 and a water divider 9. The diversion valve 8 is located at one end near the liquid outlet channel 104. A cap 10 is installed at the opening of the liquid outlet 105. The gun body 101 is snapped with an outer cover 11 on the side near the slot 108. The piston 4 is movably installed inside the piston chamber 103. A piston sleeve 5 is fixedly installed at one end of the piston 4. A handle assembly 6 is provided on the side of the gun body assembly 1 away from the outer cover 11. An external spring assembly 7 is provided between the handle assembly 6 and the gun body assembly 1.

[0031] The inverted section assembly 2 includes an inverted section body 201. An outlet pipe 202 is integrally formed on one side of the top of the inverted section body 201, and an inlet pipe 203 is integrally formed on one side of the bottom of the inverted section body 201 near the outlet pipe 202. An inlet groove 204 is formed inside the inverted section body 201, communicating with both the outlet pipe 202 and the inlet pipe 203. A transverse inlet groove 206 is formed through one inner wall of the inlet groove 204, and the transverse inlet groove 206 is located away from the inlet groove. A side seal 207 is provided at one end of the opening of 204. The side seal 207 is fixed after being installed and seals one end of the transverse liquid inlet 206 to prevent liquid leakage. An inverted liquid inlet 205 is provided through the inner wall of the top of the transverse liquid inlet 206. An inverted ball valve 208 is movably installed inside the inverted liquid inlet 205. An inverted liquid inlet 209 is integrally formed at the bottom end of the inverted section body 201. The bottom end of the inverted section body 201 is close to the liquid inlet pipe 203. One side edge is integrally formed with an exhaust notch 210, which connects to the exhaust port 107, allowing for smoother exhaust and improving the spraying effect. A suction tube 12 is inserted into the bottom end of the inlet pipe 203. Due to the inverted assembly 2, when spraying liquid in the forward direction, the inverted ball valve 208 blocks the inverted inlet port 205, and the liquid in the bottle enters the piston chamber 1 through the suction tube 12, the inlet pipe 203, the inlet groove 204, and the outlet pipe 202. Inside the bottle 03, the liquid is sprayed out through the liquid outlet channel 104. When the bottle is inverted, the straw 12 cannot enter the liquid, but the inverted ball valve 208 opens the inverted liquid inlet 205. The liquid in the bottle enters the inverted liquid inlet 205 through the inverted liquid inlet groove 209. Finally, when the handle assembly 6 is pressed, the liquid enters the liquid inlet groove 204 through the inverted liquid inlet 205 and the side seal 207, forming a forward spraying effect. This allows for both forward and inverted spraying, ensuring that the product in the bottle is completely sprayed out without waste.

[0032] The spring valve assembly 13 includes a ring 1301, a sealing spherical surface 1302 at the bottom of the ring 1301, and multiple elastic ribs 1303 arranged in a ring array integrally formed at the bottom end of the ring 1301. The bottom end of the elastic ribs 1303 is integrally formed with the top edge of the sealing spherical surface 1302. The bottom end of the sealing spherical surface 1302 is circular and is adapted to the top opening of the liquid outlet pipe 202. The middle part of the elastic ribs 1303 is bent outward. The top end of the ring 1301 is fitted and connected to the top inner wall of the liquid inlet 106. By replacing the traditional ball valve with the spring valve assembly 13, the problem of poor liquid spraying effect when the product is inverted is improved because the ball valve leaves the sealing position due to gravity.

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

[0034] Working principle of this utility model:

[0035] In use, the piston 4 moves within the piston chamber 103 by pressing the handle assembly 6, causing the gas inside the gun assembly 1 to flow and the pressure to decrease. The pressure outside the gun assembly 1 remains unchanged, creating a pressure difference between the inside and outside of the gun assembly 1. Liquid is drawn in through the suction tube 12, causing the sealing spherical surface 1302 to bounce upwards and be drawn into the piston chamber 103. When the wrench is squeezed again, the elastic rib 1303 immediately returns to its original shape after the liquid is drawn in, and the sealing spherical surface 1302 rebounds to the sealing surface, preventing the drawn-in liquid from flowing back into the bottle. When the wrench is squeezed, the piston 4 moves downwards, creating a pressure difference. When the liquid is discharged from the outlet, a high-speed airflow is instantly generated, atomizing the liquid and driving it out of the product.

[0036] When using the inverted spray, the product is inverted, and the liquid flows naturally into the interior from the inverted liquid inlet 209. The inverted ball valve 208 leaves the sealing surface due to gravity, and the squeeze handle assembly 6 creates a pressure difference. The liquid enters from the inverted liquid inlet 205 on the inverted section assembly 2, flows into the inlet 204 from the transverse liquid inlet 206, and enters the piston chamber 103. After that, the liquid is sprayed out in the same way as the forward spray.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
