Combination Straight Stream and Spray Fire Nozzle

The direct current (DC) spray fire water gun is a core piece of equipment in modern fire-fighting rescue systems, integrating DC jet attack and spray protection functionalities into one. Through innovative structural design and fluid dynamics optimization, it delivers the practical value of multi-functionality in a single tool—acting as both a "sharp weapon" for long-range fire source targeting and a "safety barrier" for close-quarters operators.
By combining dual-mode jet switching, ergonomic structural design, and high-pressure/corrosion-resistant materials, it achieves dual capabilities: long-range offensive attack and close-range defensive protection. It not only solves the inefficiency problem of traditional water guns—where single functions require coordinating multiple pieces of equipment—but also becomes a versatile workhorse for fire response in construction, chemical, forestry, and other fields, thanks to its safety redundancy and scenario adaptability.
Ultimately, it sets a benchmark for modern fire-fighting equipment: enhancing firefighting efficiency while ensuring firefighter safety, and redefining how frontline responders tackle diverse fire scenarios with one reliable tool.

Product Formation

A direct current (DC) spray fire water gun is a fire-fighting equipment that integrates both direct current (DC) jet and spray jet functions. Through its internal structural design, it enables rapid switching between the two jet modes, combining the capabilities of long-range targeted firefighting and large-area close-range protection/cooling.

By leveraging "modular structure + fluid dynamics optimization + ergonomics design", it achieves dual-function integration of DC targeted attack and spray protection—serving as both a core firefighting tool and a safety barrier for firefighters during close-quarters combat.

Its product development revolves around three key dimensions: high-efficiency firefighting, stable reliability, and easy operation. This makes it suitable for fire response in diverse scenarios such as buildings, forests, and chemical facilities. Ultimately, it is an indispensable basic piece of equipment in modern fire rescue systems.

Product Features

As a core piece of modern fire-fighting equipment, the direct current (DC) spray fire water gun centers its features around four core values: integrated functionality, efficient firefighting, safety & reliability, and ease of operation. Details are as follows:

Free Switching Between DC Jet and Spray Jet: Equipped with an efficient switching mechanism (e.g., threaded knobs, push-lock buttons, or toggle switches), it enables mode conversion between DC and spray in ≤1 second—no need to replace the water gun. This addresses the pain point of traditional single-function water guns, which require carrying multiple pieces of equipment.
Intuitive Blind Operation: Features clear mode-switching labels (red/blue color coding to distinguish spray/DC). The grip is designed with anti-slip protrusions and an ergonomic curved shape that conforms to the palm, allowing single-handed switching even in wet/slippery conditions—with an operation error rate of <2%.
Lightweight and Ergonomic Grip: The main body is made of aluminum alloy or engineering plastic, keeping weight between 0.8–1.2kg. The center of gravity is close to the hand (≤15cm from the end of the grip), reducing fatigue during prolonged use and meeting firefighters’ single-person load requirements.
Corrosion and Aging Resistance: The surface undergoes electrostatic spraying or epoxy resin treatment, offering salt spray corrosion resistance (compliant with GB/T 10125-2021). It adapts to corrosive environments like humid, chemical, or marine settings, with a service life of ≥5 years.
Anti-Backflow Structure: A built-in check valve in the inlet interface automatically closes when water supply stops, preventing backflow of water from the hose to damage equipment and reducing the risk of secondary failures.
Versatile Scenario Adaptability: Suitable for multiple fire scenarios (e.g., buildings, chemicals, forests), it reduces equipment redundancy and simplifies on-site deployment.
