Description

Technical Field

[0001] This utility model relates to the field of liquid spraying device technology, and in particular to a nozzle structure that can be used in multiple directions. Background Technology

[0002] A push-button spray nozzle is a common manual liquid dispensing device. Its basic components include a pump body fixed to the bottle neck by threads, an internal piston mechanism, a straw inserted into the liquid in the bottle, and a nozzle. When the user repeatedly presses the trigger or the pump head, the piston moves within the pump chamber, thereby generating negative pressure that draws the liquid from the bottle through the straw. After being pressurized through the internal channel, the liquid is sprayed out from the nozzle in a mist or beam form, achieving controllable, quantitative, and uniform spraying of the liquid in the bottle. It is widely used in many fields such as cleaning agents, cosmetics, and gardening products.

[0003] In existing technologies, the use of conventional nozzles largely depends on the specific placement of the bottle. They can usually only work normally in the upright position. When users try to invert or tilt the bottle to a large angle, the liquid absorption path depends on the fixed suction tube and the air path lacks an effective anti-backflow mechanism, which often leads to the inability to effectively absorb liquid or the liquid entering the air pressure channel. This not only causes the spray function to malfunction, but may also cause contamination and damage to internal components. Improvements are needed. Utility Model Content

[0021] 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.

[0022] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, this utility model provides a technical solution: a multi-directional spray head structure, including a spray head structure 1, a top cover structure 2 fixedly connected to the spray head structure 1, a square spray head 3 mounted on the spray head structure 1, a pressing trigger 5 rotatably connected to one end of the spray head structure 1 near the square spray head 3, a plastic spring rod 4 installed between the spray head structure 1 and the pressing trigger 5, a pressure boosting piston 7 installed on the pressing trigger 5, and an internal threaded connector 6 connected to the bottom of the spray head structure 1 for threaded connection with the bottle neck; in this design: the spray head structure 1, as the main body, is fixedly connected to the top cover structure 2, which can ensure the stability and sealing of the top cover and prevent liquid leakage; the square spray head 3 is directly mounted on the spray head structure 1. As the spray outlet, it is responsible for the final spraying of the liquid. At one end near the square nozzle 3, the nozzle structure 1 is connected to the push trigger 5 by a rotating snap-fit, allowing the trigger to rotate around an axis for easy user operation. The plastic spring rod 4 installed between the nozzle structure 1 and the push trigger 5 provides an elastic reset function, automatically pushing the trigger back to the initial position after being pressed, enabling continuous use. The pressure boosting piston 7 installed on the push trigger 5 serves as a gas-driven component. When the user presses the trigger, the piston moves accordingly, generating a pressure change inside the nozzle, thereby driving the liquid flow. The internal threaded connector 6 connected to the bottom of the nozzle structure 1 is connected to the bottle mouth via threads, ensuring that the entire nozzle can be reliably fixed to the container and forming a sealed channel. The top cover structure 2 includes a top cover body 21. A tail hook 22 is provided at one end of the inner wall of the top cover body 21, and a middle hook 23 is provided in the middle of the inner wall of the top cover body 21. In this design, the tail hook 22 and the middle hook 23 are provided on the inner wall of the top cover body 21. The fastening and secure fixing is achieved by snapping. The tail hook 22 is located at one end of the inner wall to provide end locking, and the middle hook 23 is located in the middle of the inner wall to enhance the overall stability, thereby ensuring that the top cover structure 2 can fit tightly after installation and resist falling off due to external forces. Furthermore, the nozzle structure 1 includes a nozzle body 11, on which a tail end buckle 12 and a middle groove 13 are provided. The tail end buckle 12 is engaged with the tail end hook 22, and the middle groove 13 is engaged with the middle hook 23. In this design, the tail end buckle 12 and the middle groove 13 provided on the nozzle body 11 achieve a firm lock between the nozzle body 11 and the top cover body 21 through the engagement. When the top cover structure 2 is installed, the tail end hook 22 will engage with the tail end buckle 12 of the nozzle body 11, and at the same time, the middle hook 23 will be embedded in the middle groove 13, forming a stable fixed structure. Furthermore, the nozzle body 11 is equipped with a piston cylinder 17, and the booster piston 7 is slidably disposed in the piston cylinder 17. The piston cylinder 17 is connected to the air pipe 18. In this design, the piston cylinder 17 on the nozzle body 11 is a sealed chamber, and the booster piston 7 is disposed in the piston cylinder 17 in a piston manner. When the user operates and presses the trigger 5, it will drive the booster piston 7 to move linearly in the piston cylinder 17. The design that the piston cylinder 17 is directly connected to the air pipe 18 makes the internal space of the piston cylinder 17 and the air pipe 18 form a continuous air passage. Furthermore, the nozzle body 11 has a nozzle end 15 at the outlet end that inserts into the square nozzle 3. The outer wall of the nozzle end 15 has an end clip 14 that engages with the square nozzle 3. The bottom of the nozzle body 11 has a bottom clip 16 that engages with the internal thread connector 6. The internal thread connector 6 is threadedly connected to the bottle mouth of the bottle. A sealing gasket can also be added between the internal thread connector 6 and the bottle mouth to further increase the sealing performance. In this design, the nozzle end 15 at the outlet end of the nozzle body 11 is positioned by inserting into the square nozzle 3 and is secured by the end clip 14 on its outer wall, ensuring that the square nozzle 3 can be quickly and securely installed in the designated position and preventing it from loosening under spray pressure. At the same time, the bottom clip 16 at the bottom of the nozzle body 11 engages with the internal thread connector 6, so that the internal thread connector 6 can be stably connected to the nozzle body 11. The internal thread connector 6 itself is threadedly connected to the bottle mouth of the bottle.

[0023] In this embodiment, the nozzle structure 1, as the main body, is connected to the bottle mouth threadedly through the internal threaded connector 6 and a sealing gasket is added to ensure basic sealing. The nozzle body 11 of the nozzle structure 1 is stably connected to the internal threaded connector 6 through the bottom buckle 16 at its bottom. During operation, the pressurizing piston 7 is driven to move within the piston cylinder 17 of the nozzle body 11 by rotating the pressurizing trigger 5, which is attached to the nozzle structure 1. The piston cylinder 17 is connected to the air pipe 18 to introduce the generated air pressure into the bottle. The plastic spring rod 4 between the nozzle structure 1 and the pressurizing trigger 5 ensures that the trigger automatically resets after each press for continuous use. The water outlet end of the nozzle body 11 is inserted through the nozzle end 15 and secured to the square nozzle 3 by the end buckle 14 to form a reliable spray outlet. At the same time, the top cover body 21 of the top cover structure 2 is secured to the corresponding end buckle 12 and middle groove 13 on the nozzle body 11 by the tail hook 22 and middle hook 23 on its inner wall, respectively, thereby firmly covering and sealing the entire internal water channel of the nozzle. This design constructs a complete, sealed, and robust pressure transmission and liquid spraying system from the bottle body to the square nozzle 3. It ensures that users can generate stable air pressure and drive the liquid to spray reliably by simply pressing the bottle, whether it is used upright or upside down. At the same time, the snap-fit ​​and threaded connection between all components ensures ease of assembly, overall structural strength, and long-term sealing reliability.

[0024] Example 2 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the nozzle structure 1 includes a nozzle body 11. An air pipe 18 is provided inside the bottom port of the nozzle body 11. A ball bearing chamber cover 19 is inserted into the bottom of the air pipe 18. A ball bearing 110 is provided inside the ball bearing chamber cover 19. A suction pipe connecting pipe 111 with a suction pipe inserted is provided at the bottom of the nozzle body 11 on one side of the air pipe 18. A water channel 112 is connected to the bottom of the suction pipe connecting pipe 111. A water channel 112 is connected to a water passage 114 that is connected to an internal threaded connector 6. The water passage 114 is located inside the water channel pipe 113. The water channel pipe 113 is connected to the internal threaded connector 6 through a channel provided inside the nozzle structure 11 on the side of the suction pipe connecting pipe 111. A ball bearing container 115 that is connected to the water passage 114 is provided inside the water channel pipe 113. A ball bearing 116 is provided inside the ball bearing container 115. An end cap 117 is installed at the port of the ball bearing container 115. In this design: the ball bearing cap 19 inserted into the bottom of the gas tube 18 and the ball bearing 110 inside it constitute a one-way valve for the gas passage, while the suction tube connecting pipe 111 inserted into the suction tube serves as the main inlet for the liquid when the tube is upright. The water channel 112 connected to the bottom of the suction tube connecting pipe 111 is also connected to the water channel 114 set in the water channel pipe 113. The water channel pipe 113 is connected to the internal threaded connector 6 through the side channel to enter the internal space of the bottle. The water channel pipe 113 is also equipped with a ball bearing container 115 connected to the water channel 114 and a ball bearing 116 inside it. The port of the ball bearing container 115 is closed by the end cap 117. This design automatically switches the fluid path by utilizing the changes in the gravitational position of ball bearing 110 and ball bearing 216 under different postures. When in the correct position, ball 110 falls to the bottom of ball chamber cover 19 without blocking air pipe 18, and ball 216 falls to the bottom of ball container tube 115 without blocking the connection between water channel 114 and water channel 112. Liquid enters water channel 112 from the suction pipe through suction pipe connecting pipe 111. When the bottle is inverted or tilted, the first ball 110 rolls back under the action of gravity and blocks the port connecting the gas tube 18 to the inside of the bottle to prevent liquid from flowing back into the gas path. At the same time, the second ball 116 rolls to the top of the ball container tube 115 so that the water passage 114 and the water channel 112 form a passage. The liquid inside the bottle fills the water channel tube 113 under the action of gravity and can enter the water channel 112 through the water passage 114. This design enables the nozzle to automatically select the correct liquid inlet path without manual adjustment in different usage postures such as upright, inverted and tilted. It ensures that no matter how the bottle is placed, the air pressure generated by pressing the trigger 5 can effectively push the liquid in the bottle through the corresponding channel to the square nozzle 3 and spray it out, which greatly improves the convenience and reliability of use. Furthermore, water channel 112 is connected to an intermediate water channel 121 located inside the nozzle body 11. A check cover 120 is provided at the connection between the intermediate water channel 121 and water channel 112. The other end of the intermediate water channel 121 is connected to a water outlet pipe 118 located on the nozzle body 11. A water sealing valve 119 is provided inside the water outlet pipe 118. The water outlet pipe 118 is connected to the nozzle of the square nozzle 3 through a water channel located inside the nozzle body 11. In this design: Waterway 112 serves as a channel for liquid to flow in during both upright and inverted states. Waterway 112 connects to the intermediate waterway 121 within the nozzle body 11. A check cap 120 is installed at the connection point between the nozzle body 11 and the intermediate waterway 121, allowing liquid to flow unidirectionally from waterway 112 into the intermediate waterway 121. This effectively prevents liquid from flowing back from the intermediate waterway 121 into waterway 112 when pressure changes occur, thus avoiding potential backflow contamination and pressure loss. Furthermore, the intermediate waterway 121... The other end is connected to the water outlet pipe 118, and the water sealing valve 119 installed in the water outlet pipe 118 constitutes a normally closed valve. When the top cover structure 2 is not covered, the sealing effect of the water sealing valve 119 can prevent the liquid in the bottle from leaking from the square nozzle 3 under static pressure or accidental tilting. Only when the trigger 5 is pressed to generate sufficient pressure can the liquid push open the water sealing valve 119 and flow out. Finally, the water outlet pipe 118 is connected to the nozzle of the square nozzle 3 through the water channel inside the nozzle body 11, and the pressurized liquid is guided to the final spray point. Furthermore, the inner wall of the top cover body 21 is also provided with a sealing rod 24 that is inserted into the sealing valve 119, and the bottom of the top cover body 21 corresponding to the sealing rod 24 is provided with a cap corresponding to the water outlet pipe 118. In this design: the sealing rod 24 provided on the inner wall of the top cover body 21 can be inserted into and press against the sealing valve 119 in the water outlet pipe 118 when the top cover body 21 is installed. This action provides downward mechanical pressure, ensuring that the sealing valve 119 can maintain a good sealing state even when the internal liquid static pressure or external temperature changes cause pressure fluctuations, thereby greatly reducing the leakage of liquid from the square nozzle 3; at the same time, the cap provided at the bottom of the top cover body 21 corresponding to the sealing rod 24 forms a corresponding fit with the port of the water outlet pipe 118 below. When the top cover structure 2 is closed, the top cover structure 2 will tightly cover the outlet of the water outlet pipe 118, thereby constructing a second physical barrier. This not only prevents external dust, impurities and other pollutants from entering the water outlet pipe 118 and the internal water system, avoiding nozzle blockage and liquid contamination, but also effectively reduces the trace evaporation that may occur when the liquid in the bottle passes through the valve body.

[0025] In this embodiment, the ball bearing 110 at the bottom of the air pipe 18 and the ball bearing housing cover 19 constitute a one-way valve for the air circuit, while the ball bearing 116 and the ball bearing housing 115 in the water pipe 113 constitute a liquid circuit switching valve. When in the correct position, ball bearing 110 does not block the air pipe 18 and ball bearing 2 116 does not block the water passage 114. Liquid flows from the suction pipe 111 through water passage 112 to the middle water passage 121. When inverted or tilted, ball bearing 110 blocks air pipe 18 to prevent liquid backflow, while ball bearing 116 moves to connect water channel 114 with water channel 112, and liquid enters water channel 112 from water pipe 113. Meanwhile, the check cap 120 at the connection between waterway 112 and intermediate waterway 121 ensures unidirectional flow of liquid and prevents backflow, while the sealing valve 119 in the outlet pipe 118 is normally closed when not in use to prevent leakage. It only opens when the trigger 5 is pressed to generate sufficient pressure, allowing the liquid to flow to the square nozzle 3. Furthermore, to further enhance the sealing performance, a sealing rod 24 and a corresponding cap are provided on the main body 21 of the top cover structure 2. When the top cover is closed, the sealing rod 24 is inserted into and presses against the water sealing valve 119 to provide an additional mechanical seal, while the cap at the bottom of the water sealing valve 119 physically covers the outlet of the water pipe 118, effectively preventing dust and pollution.

[0026] Working principle: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, this utility model can be used in upright, inverted, and tilted states, specifically: When in the upright position: The user presses the press trigger 5 to push the pressurizing piston 7 into the piston cylinder 17. The gas in the piston cylinder 17 enters the bottle body through the air pipe 18. The air pressure in the bottle increases, forcing the liquid in the bottle to be squeezed into the suction pipe 111 through the suction pipe. The liquid enters the middle water channel 121 through the water channel 112. After passing through the channel of the water outlet pipe 118 and the nozzle body 11, it is sprayed out by the square nozzle 3. During this process, the first ball 110 falls into the bottom of the ball chamber cover 19 under the action of gravity. It does not contact the passage between the air pipe 18 and the piston cylinder 17, so the gas in the piston cylinder 17 can enter the bottle through the air pipe 18. As the liquid enters the water channel 112 through the suction pipe 111, since the inside of the water channel 113 is connected to the space inside the bottle, the high-pressure gas in the bottle will also suppress the second ball 116. Combined with the fact that the second ball 116 is at the bottom of the ball container tube 115 under the action of gravity, and the resistance of the liquid entering the middle water channel 121 from the water channel 112 is small, the second ball 116 can always be at the bottom of the ball container tube 115 under this condition, and will not affect the liquid ejection process in the upright state of this utility model. When used upside down or tilted: First, under the action of gravity, ball bearing 110 will fit against the channel interface between piston cylinder 17 and air pipe 18, and ball bearing 2 116 will be located at the end of ball bearing tube 115 near end cap 117 under the action of gravity. At this time, water channel 114 and water channel 112 are connected, and the liquid in the bottle will fill the internal threaded joint 6 and water channel 113 under the action of gravity. Therefore, in the inverted and tilted states, when the user presses the trigger 5 to move the pressurizing piston 7 into the piston cylinder 17, the air in the piston cylinder 17 enters the bottle through the air pipe 18. The high pressure in the bottle forces the liquid to enter the water channel 112 through the water passage 114. Under pressure, the liquid in the water channel 112 enters the middle water channel 121 and, after passing through the sealing valve 119 in the water outlet pipe 118, is sprayed out through the channel in the nozzle body 11 by the square nozzle 3.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
