Examples

With reference to fig. 1 to 13, the present embodiment provides a switch structure for a spray gun, which includes a valve rod 1, a toggle 2, a water passing member 3 and a water stopping member 4. The water passing member 3 is provided with a water flow channel 31 and a moving cavity 32, the water inlet end of the water passing member 3 is used for being connected with a water inlet pipe, the water stopping member 4 is arranged at the water outlet end of the water passing member 3, and water in the water flow channel 31 flows to a spray head part (not shown) of the spray gun through a water outlet 41 of the water stopping member 4 to be supplied to a user side; the valve rod 1 is arranged in the moving cavity 32, and the toggle knob 2 is driven by an operable mode to enable the valve rod 1 to move between an opening position and a closing position; when the valve rod 1 moves from the closed position to the open position, the water inlet section of the water outlet 41 gradually increases. Referring to fig. 3 and 4, when the valve rod 1 is in the open position, the water inlet section of the water outlet 41 is the largest, and the water outlet amount of the water outlet 41 is the largest. Referring to fig. 1 and 2, when the valve rod 1 is in the closed position, the water inlet section of the water outlet 41 is minimum, and at this time, no water is discharged from the water outlet 41. It is easily understood that the user can move the valve rod 1 to any position between the open position and the closed position by moving the toggle button 2. For example, when the user needs to adjust the water flow, the user can gradually move the valve rod 1 from the closed position to the open position by controlling the toggle button 2, the water flow of the water outlet 41 is gradually increased in the moving process, and after the user adjusts the water flow required by the user, the user stops applying force to the toggle button 2, so that the water inlet section of the water outlet 41 is kept at the adjusted position, and stepless adjustment of the water flow is realized.

In addition, the valve rod 1 is sleeved with a first sealing ring 11 and a second sealing ring 12, the first sealing ring 11 is used for sealing with the water stop piece 4, the second sealing ring 12 is used for sealing with the moving cavity 32, the first sealing ring 11 and the second sealing ring 12 are equal in size, and when the valve rod 1 is in the closed position, the water flow pressure on the first sealing ring 11 and the water flow pressure on the second sealing ring 12 are the same. Specifically, valve rod 1 periphery is equipped with the seal groove, and the sealing washer cover is arranged in the seal groove, and when valve rod 1 removed, the sealing washer removed thereupon. The second sealing ring 12 is always sealed with the sealing cavity in the process that the valve rod 1 moves from the opening position to the closing position, and the first sealing ring 11 is only sealed with the water stop piece 4 when the valve rod 1 is in the closing position.

It is easy to understand that, when the first sealing ring 11 is sealed with the water stop 4, the water flow in the water flow channel 31 applies pressure to the first sealing ring 11 and the second sealing ring 12, because the first sealing ring and the second sealing ring 12 are located at two sides of the water flow, and the two sealing rings are equally large, that is, the stressed areas of the two sealing rings are the same, for example, the water flow pressure applied to the first sealing ring 11 is F1, the water flow pressure applied to the second sealing ring 12 is F2, when the valve rod 1 is at the closed position, the sizes of F1 and F2 are equal, and the directions are opposite, so that the water flow pressures at two sides of the valve rod 1 are offset, and the water flow pressure does not need to be overcome when the toggle 2 is toggled, thereby ensuring the operation hand feeling of the toggle 2, and facilitating the use of users.

It should be noted that, in this embodiment, not only the opening and closing of the water outlet 41 can be controlled by adjusting the toggle button 2, but also the size of the water inlet cross section of the water outlet 41 can be regulated, so as to adjust the water outlet flow. In addition, through the configuration of the equal-size sealing rings, the water flow pressure on the sealing rings on the two sides of the valve rod 1 is equal, the light hand feeling of the operation of the toggle button 2 is realized, and the use by a user is facilitated.

Preferably, a circumferential seal is adopted between the first seal ring 11 and the water stop member 4, a tapered surface 42 is arranged at the water inlet end of the water stop member 4, which facilitates the first seal ring 11 to move to a sealing position, and the tapered surface 42 can be set to be a chamfer angle with an angle of 60 degrees, 45 degrees or 30 degrees, so as to reduce the abrasion of the first seal ring 11 in the moving process and improve the service life of the first seal ring 11.

On the basis of the above embodiment, an alternative embodiment of the present invention further includes a connecting rod 5 for connecting the toggle button 2, wherein the connecting rod 5 is shaped like a Chinese character 'ji', and is provided with a rotating portion 51 and a pushing portion 52. The valve rod 1 is concavely provided with a driving groove 13, and the driving groove 13 is used for being matched with the pushing part 52. The water passing member 3 is provided with a rotating groove 33 corresponding to the rotating part 51, and the rotating part 51 is accommodated in the rotating groove 33 to rotate. Through dialling to turn round 2 for rotating part 51 rotates along with it, and then drives promotion portion 52 swing, when dialling to the leftmost position at dialling to turn round 2, valve rod 1 moves to closed position under the driving of promotion portion 52, when dialling to the rightmost position at dialling to turn round 2, valve rod 1 moves to open position under the driving of promotion portion 52.

In another embodiment, the dial knob 2 is provided with a first fitting location 21, the rotating portion 51 is provided with a second fitting location 511, and the first fitting location 21 is connected with the second fitting location 511 in a matching manner, so that the dial knob 2 can drive the rotating portion 51 to rotate, thereby driving the pushing portion 52 to abut against the valve rod 1 to move. In this embodiment, the first fitting portion 21 is a square fitting hole, the second fitting portion 511 is a square column disposed to be adjacent to the square fitting hole, and the first fitting portion 21 is fitted into the second fitting portion 511, so that the toggle 2 is linked with the rotating portion 51.

On the basis of the above embodiment, in an alternative embodiment of the present invention, the end of the valve stem 1 close to the water inlet/outlet 4 is provided with a water-discharging portion 14. Preferably, the water-dispersing portion 14 is a cross-shaped protrusion, and the water flow is scattered by the water-dispersing portion 14 after entering the water outlet 41, so that the water flow is more uniform when flowing into the shower head portion, and the noise generated by water flow impact can be reduced.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
