Description

Technical Field

[0001] The utility model relates to the technical field of kitchen and bathroom, in particular to a water flow switching structure, a water channel switching system and a spray gun with shoulder spray. Background Art

[0002] Traditional water outlets mostly adopt the structure of peripheral or frontal water outlet. In order to improve the water outlet function, many water outlets combine spray guns and shower heads, and develop water outlet structures with end water outlet and peripheral water outlet. Under the switching action of the switching switch, the end spray gun water or peripheral shower water outlet is selected, so that the water outlet has both spray gun and shower functions. However, for the water outlet with the above-mentioned composite functions, the switching switch is often more complicated, especially in the scene where there are multiple water outlet modes to choose from when in the shower function. When the user switches the water channel, it is inevitable that the user switches to the spray gun function when the shower function is used, which brings trouble to the use. In addition, when the water channel switching structure is relatively complex as a whole, there is also the problem that the switching structure is large in size, and then the size of the water outlet is also large, and it is also difficult to assemble. For this reason, the present invention provides a water switching structure, which can separate part of the water channel switching function, and at the same time solves the problem of space occupation by the switching structure with a clever structure.

[0007] The utility model provides a water-flow switching rod which not only has the switching function of the switching rod, but can also control and switch any first water outlet channel to be connected with the second water inlet channel, thereby realizing the water path switching of the first water outlet channel, and separates the switching switch of the first water outlet channel from the main switch and sets it independently, thereby avoiding the user from making an erroneous operation when wanting to switch the first water outlet channel. In addition, the water-flow switching rod itself also has a second water outlet channel which is always connected with the first water inlet channel, so that the switching switch of the first water outlet channel and the second water outlet channel are cleverly combined together, thereby avoiding space waste as much as possible, thereby avoiding the problem of the need to excessively expand the size of the water outlet caused by the independent setting of the switching switch of the first water outlet channel.

The part of the U-shaped opening opposite to the protruding column also forms an arc-shaped clamping surface. By rotating the rotating seat 51 to adjust the distance between the two arc-shaped clamping surfaces, the installation height of the spray gun seat 5 on the shower rod 6 can be adjusted. The other end of the fixed seat 53 is provided with a shower head plug interface, so that the spray gun seat 5 also has the function of placing a shower head.

[0067] The spray gun with shoulder spray provided by the utility model can, when in use, select the shoulder spray water nozzle 4 or the spray gun water nozzle 3 to discharge water through the main switching switch 2, and switch the water outlet state of the shoulder spray water nozzle 4 through the water flow switching rod 15, that is, the switching operation of the shoulder spray water nozzle 4 and the spray gun water nozzle 3 and the switching operation inside the shoulder spray water nozzle 4 are divided into two independent control switches, which can avoid the user's misoperation. In addition, combined with the water flow switching structure provided in the first aspect, a reasonable layout of the functional structure is achieved, and the switching operation structure inside the shoulder spray water nozzle 4 can be extended and designed at the end of the water outlet body 1, staggered with the main switching switch 2 and the water inlet end of the water outlet body 1, to avoid the two switch structures being squeezed together, resulting in one end of the water outlet body 1 being too large and the other end being fully utilized. The appearance of the entire spray gun is uniform and coordinated. At the same time, with a clever layout, space waste is avoided and the overall size is also small.
