AI Technical Summary

Technical Problem

Existing spray guns have limited functionality, typically only allowing water to flow or stop according to pre-drilled holes at the nozzle, and their limited water flow patterns make it difficult to meet diverse user needs.

Method used

A multi-functional adjustable flow spray gun was designed. By operating the handle to switch the valve core to select the water outlet, two water output modes can be switched: gentle aerated water and high-pressure water flow, to meet different usage needs.

Benefits of technology

It achieves multi-functionality of the spray gun, allowing switching between two water output modes, enhancing the user experience and meeting diverse usage needs.

Description

Multifunctional flow adjustable handheld water outlet device TECHNICAL FIELD

[0001] The present application belongs to the technical field of bathroom equipment, and relates to a multifunctional flow adjustable spray gun. BACKGROUND

[0002] The spray gun has a wide range of uses in life and can be used in gardens, balconies, car washes and other places, and can also be used as a pull-out faucet in kitchens or bathrooms. The latter is connected through a hose, and when in use, the hose is pulled out. The handheld spray gun can be used flexibly in a larger range, which is very convenient. TECHNICAL PROBLEM

[0003] However, the existing spray gun can only realize water outlet or water stop operation according to the hole position already opened at the outlet of the spray gun, which is not only single in function, but also usually has only one water outlet mode. In the face of the increasing different needs of users, the existing spray gun is difficult to provide a better experience. TECHNICAL SOLUTION

[0004] Therefore, in view of the structure and defects of the existing spray gun, it is an inevitable trend to provide a water outlet spray gun with more functions. ADVANTAGEOUS EFFECTS

[0005] The purpose of the present application is to solve the problem of single function of the existing spray gun by providing a multifunctional flow adjustable spray gun. BRIEF DESCRIPTION OF DRAWINGS

[0006] Figure 1 is a longitudinal sectional view of the spray gun. Figure 2 is a transverse sectional view of the spray gun. Figure 3 is a schematic view of the overall structure of the spray gun. Figure 4 is an exploded view of the spray gun. BEST MODE FOR CARRYING OUT THE INVENTION

[0007] When the spray gun is in use, the valve core can be switched to select water outlet port one or water outlet port two through the operation handle, so that the water flow can flow out through water outlet cavity one and water outlet hole one in turn, or through water outlet cavity two and water outlet hole two in turn, so that the spray gun can realize the effect of switching between two water outlet modes, meeting different use requirements of people. EMBODIMENTS OF THE INVENTION

[0008] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments. As shown in FIGS. 1-4, the present spray gun comprises a main body 3 having a water inlet end 1 and a water outlet end 2, a valve core 4 fixed in the main body 3, and a handle 5 provided outside the main body 3 and connected with the valve core 4. The valve core 4 has a water outlet 1 6 and a water outlet 2 7, the water outlet end 2 has a water outlet cavity 1 8 communicating with the water outlet 1 6 and a water outlet cavity 2 9 communicating with the water outlet 2 7, and the end of the water outlet end 2 has a water outlet hole 1 0 communicating with the water outlet cavity 1 8 and a water outlet hole 2 1 1 communicating with the water outlet cavity 2 9. A bubbler 1 2 is further provided in the water outlet cavity 1 8, and soft bubbled water can be generated through the bubbler 1 2. Specifically, the water outlet cavity 2 9 is a circular ring cavity and is arranged around the water outlet cavity 1 8, and the number of the water outlet hole 2 1 1 is several and is arranged around the water outlet hole 1 0. In use, the handle 5 can be operated to switch the valve core 4 to open the water outlet 1 6 or the water outlet 2 7, so that the water flow can flow out through the water outlet cavity 1 8 and the water outlet hole 1 0 in sequence or through the water outlet cavity 2 9 and the water outlet hole 2 1 1 in sequence, so that the spray gun can realize the effect of switching between two water outlet modes and meet the use requirements of people. At the same time, the water flow entering the water outlet cavity 1 8 generates soft bubbled water after passing through the bubbler 1 2, and the water flow entering the water outlet cavity 2 9 generates water flow with relatively high water pressure after passing through the water outlet hole 2 1 1, thereby enhancing the use function of the spray gun. Industrial applicability

[0009] Compared with the prior art, the present spray gun can realize the effect of switching between two water outlet modes, meet the use requirements of people, the water flow entering the water outlet cavity 1 generates soft bubbled water after passing through the bubbler upper channel, and the water flow entering the water outlet cavity 2 generates water flow with relatively high water pressure after passing through the water outlet hole 2, thereby enhancing the use function of the spray gun. Free content of sequence listing

[0010] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
