Description

Technical Field

[0001] This utility model relates to the field of foaming nozzle technology, specifically to a highly reliable and lightweight foaming nozzle. Background Technology

[0002] Currently, conventional foaming spray heads on the market suffer from numerous core problems, severely impacting user experience and work efficiency. Firstly, maintenance is difficult. Conventional foaming nets are prone to clogging. Due to their unreasonable structural design, cleaning requires disassembling multiple parts, a complex process that increases maintenance costs and consumes a significant amount of time. Furthermore, the foaming core is tightly integrated with the main spray head structure, making replacement inconvenient and hindering continuous and stable equipment use. Secondly, operation is inconvenient. The small capacity of the foaming liquid tank necessitates frequent replenishment for large-area spraying operations, making the process cumbersome and time-consuming. Additionally, the direct connection between the foaming liquid tank and the foaming head concentrates the overall weight during spraying, requiring strenuous operation and hindering prolonged handheld use, significantly limiting work efficiency and operating range. Utility Model Content

[0003] This invention provides a highly reliable and lightweight foaming nozzle, which aims to solve the problems of difficult maintenance and inconvenient operation of existing foaming nozzles, and improve the reliability and ease of use of the equipment.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A highly reliable and lightweight foaming nozzle includes a gas-liquid mixing tube. One end of the gas-liquid mixing tube is connected to a four-way connector. The end of the gas-liquid mixing tube away from the four-way connector is sequentially connected to a mixing screen and a nozzle. A sleeve is provided on the outside of the gas-liquid mixing tube. The two ends of the sleeve are threadedly connected to the four-way connector and the nozzle, respectively, to fix the gas-liquid mixing tube. The end of the four-way connector away from the gas-liquid mixing tube is threadedly connected to a quick-connect nozzle. The upper end of the four-way connector is threadedly connected to an air inlet regulating valve. The lower end of the four-way connector is threadedly connected to a foaming liquid quick connector. The lower end of the foaming liquid quick connector is pluggable connected to a foaming liquid soft suction tube.

[0005] Furthermore, the hybrid screen has a sheet-like mesh structure.

[0006] Furthermore, the nozzle is conical.

[0007] Furthermore, a sealing gasket is provided between the mixing screen and the nozzle.

[0008] Furthermore, a mixing pipe sealing ring is fitted onto one end of the gas-liquid mixing pipe that is close to the mixing screen.

[0009] Furthermore, a sleeve sealing ring is fitted onto one end of the four-way connector that is threadedly connected to the sleeve.

[0010] The beneficial effects achieved by this utility model are as follows: The gas-liquid mixing pipe of this invention is fixed with a sleeve thread, and the mixing screen has a sheet-like mesh structure, which is less prone to clogging than conventional foaming nets. Even if the mixing screen is clogged, it can be quickly removed for cleaning simply by disassembling the sleeve, without the need to disassemble multiple complex parts as with traditional nozzles. This greatly simplifies the cleaning process, reduces maintenance difficulty, and decreases maintenance costs and time. At the same time, the components are connected by threads, making it easy to replace the foaming spray core (such as the mixing screen, nozzle, etc.) without affecting the continuous use of the equipment.

[0011] The plug-in design of the foaming liquid quick connector and foaming liquid soft straw of this utility model supports the connection of external large-capacity liquid storage tanks. Compared with traditional small-capacity foaming liquid jugs, it can significantly reduce the number of liquid replenishments and improve the efficiency of large-area spraying operations. In addition, the soft straw replaces the traditional rigid connection of the liquid jug, reducing the weight of the hand, making the operation more flexible and labor-saving, and facilitating long-term operation.

[0012] This invention incorporates sealing gaskets and sealing rings at key connections, such as the sealing gasket between the mixing screen and the nozzle, the mixing pipe sealing ring on the gas-liquid mixing pipe, and the sleeve sealing ring between the four-way connector and the sleeve, effectively preventing gas-liquid leakage and ensuring the stability and reliability of the nozzle during operation.

[0019] The following is in conjunction with the appendix Figure 1-2 To further describe this application in detail, an embodiment of this application discloses a highly reliable and lightweight foaming nozzle. Referring to the accompanying drawings, it includes a gas-liquid mixing tube 1. One end of the gas-liquid mixing tube 1 is connected to a four-way connector 2. The end of the gas-liquid mixing tube 1 away from the four-way connector 2 is sequentially connected to a mixing screen 3 and a nozzle 4. A sleeve 5 is provided on the outside of the gas-liquid mixing tube 1. The two ends of the sleeve 5 are threadedly connected to the four-way connector 2 and the nozzle 4, respectively, to fix the gas-liquid mixing tube 1. The end of the four-way connector 2 away from the gas-liquid mixing tube 1 is threadedly connected to a quick-connect nozzle 6. The upper end of the four-way connector 2 is threadedly connected to an air inlet regulating valve 7. The lower end of the four-way connector 2 is threadedly connected to a foaming liquid quick connector 8. The lower end of the foaming liquid quick connector 8 is pluggable connected to a foaming liquid soft suction tube 12.

[0020] Furthermore, the mixing screen 3 has a sheet-like mesh structure, which is simple and easy to disassemble and clean.

[0021] Furthermore, the nozzle 4 is conical, which enables the mixed gas and liquid to be sprayed out at a specific angle and shape to ensure the foaming effect.

[0022] Furthermore, a sealing gasket 9 is provided between the mixing screen 3 and the nozzle 4 to prevent gas and liquid leakage at the connection point, thereby improving the sealing performance and reliability of the nozzle.

[0023] Furthermore, a mixing pipe sealing ring 10 is fitted onto one end of the gas-liquid mixing pipe 1 near the mixing screen 3 to further enhance the sealing performance of the gas-liquid mixing pipe 1 at the connection with other components.

[0024] Furthermore, a sleeve sealing ring 11 is fitted onto one end of the four-way connector 2 that is threadedly connected to the sleeve 5 to ensure a tight connection between the four-way connector 2 and the sleeve 5 and to prevent gas and liquid leakage.

[0025] Specifically, in actual use, this utility model: First, connect the foaming liquid soft straw 12 to the foaming liquid storage container, and achieve quick plug-and-play connection through the foaming liquid quick connector 8; then connect the air intake pipe to the air intake regulating valve 7, and control the air intake volume by adjusting the air intake regulating valve 7. The gas-liquid mixing pipe 1, the mixing screen 3, and the nozzle 4 are connected in sequence. After the gas and liquid are initially mixed in the gas-liquid mixing pipe 1, they are further uniformly mixed through the mixing screen 3, and finally sprayed out through the conical nozzle 4 to form foam.

[0026] When cleaning the mixing screen 3 is required, simply unscrew the threaded connection between the sleeve 5, the four-way connector 2, and the nozzle 4, and remove the gas-liquid mixing pipe 1. The mixing screen 3 can then be easily removed for cleaning. Throughout the entire process, the sealing gasket and sealing ring effectively prevent gas-liquid leakage, ensuring stable operation of the nozzle. Furthermore, the design of the external large-capacity liquid storage tank and flexible suction hose allows operators to easily perform long-duration, large-area foam spraying operations, greatly improving work efficiency.
