Description

Technical Field

[0001] This utility model relates to the field of spray water gun technology, specifically a fire-fighting DC spray water gun. Background Technology

[0002] Fire hoses are water-spraying tools used for extinguishing fires. When connected to a fire hose, they spray a dense and powerful stream of water. They have advantages such as long range and large water volume. Based on different jet patterns and characteristics, they can be divided into: straight stream hoses, spray hoses, and multi-purpose hoses, among which straight stream hoses and spray hoses are commonly used.

[0003] However, it still has some drawbacks. For example, when installing and using the existing DC spray water gun, it needs to be quickly connected to the water pipe. After water is injected, water pressure will be generated. After repeated use, water leakage or disconnection may occur at the connection between the water pipe and the connector, requiring reconnection and fixation. The connection between the water pipe and the connector is relatively unstable, making the operation cumbersome.

[0004] To address the aforementioned issues, this application proposes a fire-fighting direct current spray nozzle. Utility Model Content

[0005] The purpose of this utility model is to provide a fire-fighting DC spray water gun to solve the problems mentioned in the background art. In the prior art, DC spray water guns need to be quickly connected to water pipes during installation and use. After water is injected, water pressure is generated. After repeated use, water pipe and connector connections are prone to leakage or breakage, requiring reconnection and fixation. The water pipe and connector connections are relatively unstable, and the operation is cumbersome.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fire-fighting DC spray water gun, including a spray water gun body, wherein a flow regulating switch and a water shape regulating switch are provided on the upper outer surface of the spray water gun body, and the flow regulating switch is located on the upper outer surface of the water shape regulating switch; a rubber sleeve is fixedly connected to the upper outer wall of the spray water gun body; an atomizing nozzle is fixedly connected to the upper outer surface of the spray water gun body; and a water gun connector is detachably connected to the lower outer surface of the spray water gun body.

[0007] Preferably, a nut is fixedly connected to the outer surface of the upper end of the water gun connector, and a threaded hole is formed on the outer surface of the upper end of the nut.

[0008] Preferably, a gasket is provided between the spray gun body and the water gun connector.

[0009] Preferably, an external threaded sleeve is fixedly connected to the lower outer surface of the spray gun body, and the external threaded sleeve is threaded into the inner wall of the nut, and a groove is provided on the outer wall of the water gun connector.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model features a specially designed water gun connector. First, the nut at one end of the water gun connector is installed on the external threaded sleeve at the lower end of the spray gun body. Then, the connecting hose is connected to the water gun connector and secured with wire or a water pipe retainer. This allows for quick and easy installation of the spray gun and connecting hose together. The groove design allows the connecting hose to be easily secured, preventing leaks or disconnections during use. This further improves the stability of the connection between the connecting hose and the water gun connector, reducing the need for repeated re-secured connections due to instability. The water gun connector can be connected to a tap or a water hose. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Please see Figures 1-2 This utility model provides a technical solution: a fire-fighting DC spray water gun, including a spray water gun body 1. The upper outer surface of the spray water gun body 1 is provided with a flow regulating switch 2 and a water shape regulating switch 3, and the flow regulating switch 2 is located on the upper outer surface of the water shape regulating switch 3. A rubber sleeve 4 is fixedly connected to the upper outer wall of the spray water gun body 1. An atomizing nozzle 5 is fixedly connected to the upper outer surface of the spray water gun body 1. A water gun connector 6 is detachably connected to the lower outer surface of the spray water gun body 1. Its overall structure is simple and easy to install and operate. The water gun connector 6 can be connected to a tap water faucet or a water hose.

[0017] In this embodiment, as Figure 2As shown, a nut 7 is fixedly connected to the outer surface of the upper end of the water gun connector 6. A threaded hole 8 is provided on the outer surface of the upper end of the nut 7. The nut 7 allows us to easily and quickly install or remove the water gun connector 6 from the spray water gun body 1. A gasket 9 is provided between the spray water gun body 1 and the water gun connector 6. The gasket 9 further increases the sealing between the spray water gun body 1 and the water gun connector 6.
