Description

Technical Field

[0001] This utility model belongs to the field of spray bottle technology, and more specifically, relates to a multifunctional liquid spray head. Background Technology

[0002] With the improvement of living standards and the development of fields such as gardening and cleaning, electric sprayers are widely used in home garden irrigation, indoor and outdoor cleaning, and industrial surface treatment due to their advantages such as labor saving and high efficiency. Electric sprayers are mainly powered by a battery built into the nozzle, which drives a micro electric pump or diaphragm pump to work, replacing the traditional manual pressurization method. Air is forced into the sealed body of the bottle, making the air pressure inside the bottle higher than the outside atmospheric pressure, creating a pressure difference that pushes the liquid to flow to the nozzle.

[0003] Existing electric sprayers suffer from a lack of diversity in nozzle structure and structural design deficiencies. For instance, the connection between the nozzle and the sprayer is not secure enough, leading to shaking and detachment during use. This affects the internal pressurization environment and may cause liquid leakage, resulting in waste and environmental pollution from potentially harmful liquids. Furthermore, because the lower part of the nozzle is typically heavier or has a larger bottom contact surface (e.g., with a base or handle), the lower part is prone to wobbling during upper part installation, making it difficult to align the fitting holes of the upper and lower parts. (As disclosed in Chinese invention patent literature...) A leak-proof structure for an electric water sprayer (CN202221537331.5) is disclosed. This application involves creating an installation hole at the center of the bottom wall of the nozzle housing and securing it with a sealing component. The sealing component's capping section covers each air hole, thereby preventing liquid from flowing back into the nozzle housing's mounting cavity when the water sprayer is tilted, while ensuring normal operation of the electric water sprayer. However, this application does not solve the problem of the stable connection between the nozzle and the sprayer body, resulting in the risk of shaking and leakage during use, leading to leakage at the connection between the nozzle and the sprayer body. In conclusion, we need a robust liquid nozzle that can switch between spray patterns to meet increasingly diverse usage requirements. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a multifunctional liquid nozzle with a stable structure. At the same time, it can improve the sealing of the universal bottle body connection of the nozzle through reasonable assembly, thereby improving the safety of use, reducing the risk of leakage, extending the service life, and being suitable for various scenarios, thus enhancing the user experience.

[0005] This utility model discloses a multifunctional liquid nozzle, which includes an upper housing, a lower housing, a push switch, and a nozzle; the lower housing is equipped with an air pump assembly for pressurizing the inside of the container connected to the nozzle, and the pressurized liquid is sprayed out from the nozzle.

[0006] The lower housing has several mounting holes circumferentially on its inner side, and the upper housing has a fitting groove corresponding to the mounting holes circumferentially on its inner side. The fitting rod passes through the mounting hole from the bottom of the lower housing and fits into the fitting groove, which improves the stability of the connection between the upper and lower housings and prevents the connection from shaking due to the excessive weight of the lower housing.

[0007] The lower housing includes a main tank, a handle, and a water outlet, with the handle and water outlet respectively located on both sides of the main tank.

[0021] Specific Implementation Example 1: Please refer to Figures 1-7 A multifunctional liquid nozzle includes an upper housing 1, a lower housing 2, a push switch 3, and a nozzle 4; the lower housing 2 is equipped with an air pump assembly 5, which is used to pressurize the inside of the bottle body connected to the nozzle, and the pressurized liquid is sprayed out from the nozzle 4.

[0022] like Figure 2 The lower housing 2 has several mounting holes 21 circumferentially opened on its inner side, and the upper housing 1 has a fitting groove 11 corresponding to the mounting holes 21 circumferentially opened on its inner side. The fitting rod 6 passes through the mounting holes 21 from below the lower housing 2 and fits into the fitting groove 11, which improves the stability of the connection between the upper housing 1 and the lower housing 2 and avoids the connection between the two from shaking due to the excessive weight of the lower housing 1.

[0023] like Figure 3 The lower housing 2 shown includes a main tank 22, a handle 23, and a water outlet 24. The handle 23 and the water outlet 24 are respectively located on both sides of the main tank 22. The air pump assembly 5 is detachably installed inside the main tank 22. The bottom of the air pump assembly 5 is connected to the kettle body to pressurize the inside of the kettle body. The handle 3 is used to install a power supply 7, which is electrically connected to the air pump assembly 5. One end of the water outlet 24 is detachably connected to the nozzle 4, and the lower part of the other end of the water outlet 24 is connected to a water inlet pipe 9. After the inside of the kettle body is pressurized, the liquid is transported from the water inlet pipe 9 to the water outlet 24 and finally sprayed out by the nozzle 4.

[0024] The push switch 3 is installed between the upper housing 1 and the lower housing 2. The bottom of the push switch 3 is provided with a circuit board 31. The circuit board 31 is electrically connected to the air pump assembly 5.

The flow guiding arc surface 261 is in contact with the spray nozzle 251. The sliding rod 26 is slidably connected to the inner wall of the outlet 24. When the sliding rod moves towards the main tank, the flow guiding arc surface 261 is disengaged from the spray nozzle 251, thus controlling the communication between the outlet 24 and the nozzle 4.

[0026] Specifically, a through hole is provided between the main tank 22 and the outlet 24. The side of the sliding rod 26 away from the seal 25 extends from the outlet 24 into the main tank 22. A sealing ring gasket 27 is provided on the side of the through hole near the outlet 24 to prevent water entering the outlet 24 from the inlet pipe 9 from flowing into the main tank 22. The middle part of the sliding rod 26 is slidably connected to the center of the sealing ring gasket 27. A locking platform 262 is provided on the side of the sliding rod 26 near the main tank 22, which engages with the side of the press switch 3 away from the pressing end. When the press switch 3 is pressed down, it controls the sliding rod 26 to move towards the main tank 22, thereby separating the spray nozzle 251 from the guide arc surface 261, so that the liquid in the pot is transported from the inlet pipe 9 to the outlet 24, and finally sent to the nozzle 4 along the spray nozzle 251 and sprayed out.

[0027] Specifically, the main tank 22 includes an equipment cavity 222 and a connecting cavity 223 separated by a partition 221. An installation groove 224 is opened inside the equipment cavity 222. The installation groove 224 is located in the middle of the partition 221. The lower part of the air pump assembly 5 is detachably connected to the installation groove 224.

A sealing groove 226 is provided on the partition 221 inside the threaded cylinder 225. A sealing ring 227 is provided inside the sealing groove 226 to maintain the seal inside the kettle body.

[0028] Specifically, such as Figure 5 The threaded cylinder shown has a water-blocking groove 228 on its outer periphery. The water-blocking groove 228 is used to cooperate with the contact surface of the kettle body to prevent water from overflowing from the lower part of the threaded cylinder 225 to the outside, thereby preventing water leakage and improving the user experience.

[0029] Specifically, the surface of the partition 221 is provided with a pressure relief port 229, and the upper housing 1 directly above the pressure relief port 229 is provided with a sliding groove 12. A pressure relief rod 8 is provided inside the sliding groove 12. The pressure relief rod 8 is slidably connected to the sliding groove 12, thereby realizing the contact and separation between the pressure relief rod 8 and the pressure relief port 229, achieving the purpose of sealing during the normal operation of the spray bottle and releasing pressure after the pressure in the bottle body is too high.

[0030] Specifically, such as Figure 6The pressure relief rod 8 shown is provided with a limiting platform 81 at the middle end. The diameter of the limiting platform 81 is larger than the inner diameter of the sliding groove 12 and the inner diameter of the pressure relief port 229. The shaft of the pressure relief rod 8 at the upper end of the limiting platform 81 is tightly fitted with the inner wall of the sliding groove 12. A sealing gasket 82 is provided at the lower end of the limiting platform 81. The sealing gasket 82 abuts against and slides with the inner wall of the pressure relief port 229 to ensure the sealing of the interior of the pot body under the partition 221 and prevent gas inside the pot body from leaking from the pressure relief port 229.

[0031] Specifically, such as Figure 7 The nozzle 4 shown includes an adjustable nozzle head 41 and a fixed nozzle seat 42. The adjustable nozzle head 41 is connected to the fixed nozzle seat 42 by a thread. The inner wall of the fixed nozzle seat 42 away from the adjustable nozzle head 41 has a thread that matches the thread on the outer wall of the outlet 24.

[0032] Specifically, one side of the adjustable nozzle head 41 is threadedly connected to the fixed nozzle seat 42, and the other side is used for water outlet; a splash guard 411 is detachably installed on the outer periphery of the adjustable nozzle head 41, and the outer extension of the splash guard 411 is greater than the water outlet side of the adjustable nozzle head 41; a guide groove 412 is provided on the inner side of the adjustable nozzle head 411, and the guide groove 412 is close to the side of the fixed nozzle seat 42 near the adjustable nozzle head 41, so as to change the water jet angle and range by adjusting the distance between the guide groove 412 and the side of the fixed nozzle seat 42 near the adjustable nozzle head 41, thereby realizing the switching of multiple functions of the nozzle.

[0033] Specifically, a charging port 231 is provided on the side of the handle 23. The charging port 231 is electrically connected to the built-in power supply 7 to realize the charging and power supply functions and ensure the stable operation of the device for a long time.

[0034] During use, the fitting rod 6 passes through the mounting hole 21 from below the lower housing 2 and engages with the fitting groove 11. The upper housing 1, lower housing 2, press switch 3, and nozzle 4 are assembled. The liquid to be sprayed is added to the kettle body, and the kettle body is tightened to the threaded cylinder 225 of the lower housing 2, ensuring that the sealing ring 227 in the sealing groove 226 is tightly against the kettle body to prevent liquid leakage. Pressing the press switch 3 triggers the circuit board 31, which controls the air pump assembly 5 to be inserted into the kettle body to pressurize the inside of the kettle. After the inside of the kettle body is pressurized, the liquid is transported from the inlet pipe 9 to the outlet 24. At this time, because the press switch 3 engages with the locking plate 262 of the sliding rod 26, the flow guiding arc surface 261 of the traction sliding rod 26 disengages from the spray nozzle 251, and the liquid enters the nozzle 4 through the spray nozzle 251. By adjusting the distance between the guide groove 412 and the fixed nozzle seat 42 on the side close to the adjustable nozzle head 41, the water jet angle and range can be changed to meet the needs of different scenarios and realize the switching of multiple functions of the nozzle. After use or when the pressure of the kettle body is too high during use, the pressure relief rod 8 can be disengaged from the pressure relief port 229 to release excess gas inside the kettle body, reduce pressure, and ensure safe use.
