A new double tube foam gun body

Abstract

This invention proposes a novel dual-tube foam gun body, comprising a gun body with a handle at the bottom. The gun body has a first channel and a second channel on its interior sides above the handle. The ends of the first and second channels have a first interface and a second interface, respectively. One end of each channel is connected to a main channel. The first and second channels are two independent channels used to transmit water and air respectively, separating them to prevent cross-contamination. This invention effectively isolates water and air through a dual-channel control mode, completely solving the cross-contamination problem common in previous similar products, ensuring safe and environmentally friendly use. By optimizing the water and air access method, the water and air tubes are positioned perpendicular to the user's arm, reducing entanglement and friction, improving comfort and efficiency. This invention has a simple structure, is easy to use, and can be widely adopted.

Description

Technical Field

[0001] This utility model relates to the field of foam spraying equipment technology, and in particular to a novel double-tube foam gun body. Background Technology

[0002] A dual-barrel foam cleaning gun is a spraying tool that generates foam through the combined action of water and air, and is widely used in the car wash and cleaning industries. Traditional dual-barrel foam guns typically use a single channel and a single control lever to control the water and air flow. This design presents the following problems during use:

[0003] Water and gas mixing problem: Because water and gas are separated by a sealing ring within a single channel, frequent switching operations can cause the sealing ring to wear out quickly, reducing its sealing performance and leading to water and gas mixing. When the gas pressure is higher than the water pressure, the gas can introduce foamy liquid into the water pipes of residential areas, causing pollution and inconvenience.

[0004] Water and air hoses getting tangled around the arm: Traditional water and air hose connections involve inserting the hoses from the bottom of the gun handle, creating a U-shaped bend. This can easily cause the hoses to become tangled around the user's arm, affecting usability. Utility Model Content

[0005] In view of this, in order to solve the problems existing in the technical background, this utility model proposes a novel double-tube foam gun body, the specific technical solution of which is as follows:

[0006] A novel double-tube foam gun body includes a gun body, a handle at the bottom of the gun body, a first channel and a second channel provided inside the gun body on both sides above the handle, a first interface and a second interface respectively provided at the end of the first channel and the second channel, and a main channel connected to one end of the first channel and the second channel.

[0007] The first channel and the second channel are two independent channels, used to transmit water and air respectively, separating the water and air to prevent them from mixing.

[0008] Furthermore, the first and second interfaces are internally threaded to facilitate pipe connection.

[0009] Furthermore, the first and second interfaces are located above the handle to ensure that the water and air hoses are perpendicular to the user's arm, reducing hose tangling and friction.

[0010] The above technical solution has the following beneficial effects:

[0011] This invention effectively isolates water and air through a dual-channel control mode, preventing water and air from mixing due to wear of the sealing ring, ensuring safe and environmentally friendly use. By optimizing the water and air access method, the water and air pipes are positioned perpendicular to the user's arm, reducing entanglement and friction, and improving user comfort and efficiency. This invention has a simple structure, is easy to use, and can be widely adopted. 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. 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.

[0016] See Figure 1 and Figure 2 As shown, a novel dual-tube foam gun body includes a gun body with a handle 5 at the bottom. The gun body has a first channel 3 and a second channel 4 on the upper sides corresponding to the upper sides of the handle 5. The ends of the first channel 3 and the second channel 4 are respectively provided with a first interface 1 and a second interface 2. One end of the first channel 3 and the second channel 4 is connected to a main channel 6. The first channel 3 and the second channel 4 are two independent channels used to transmit water and air respectively, separating the water and air to prevent cross-contamination. The first interface 1 and the second interface 2 have internal threads to facilitate pipe connection. The first interface 1 and the second interface 2 are located above the handle 5 to ensure that the water and air pipes are perpendicular to the user's arm, reducing pipe tangling and friction.

[0017] In this embodiment, the present invention adopts a dual-channel control mode, designing two independent channels inside the gun body for controlling water and gas respectively. Independent control of each channel ensures that the on / off operation of water and gas does not interfere with each other. The water and gas interfaces, namely the first interface 1 and the second interface 2, are moved from the lower end of the gun handle 5 to the upper part. The user can pull the water and gas hoses to an appropriate position according to work needs, and then connect the hoses to the interfaces on the upper part of the gun body. After connecting the hoses, the entire foam gun can be suspended in a suitable position, and the user can adjust the foam spray direction as needed. Furthermore, the water and gas hoses are perpendicular to the user's arm, making it more labor-saving and convenient. This improvement effectively solves the problems of water and gas hoses getting tangled in the arm and easily breaking due to dragging the hoses back and forth on the ground in traditional connection methods.

[0018] This invention effectively solves common problems in existing dual-tube foam guns, such as water and air mixing, water and air hose entanglement on the arm, and easy damage to the water and air hose, through an innovative dual-channel control mode and optimized water and air access method. It improves safety, comfort, and efficiency in use and has broad application prospects and market value.
