The first water pipe 201 extends from a starting end 104 of the sliding portion 100 to a destination end 105 of the sliding portion 100, wherein the destination end 105 is opposite to the starting end 104. The starting end 104 of the sliding portion 100 refers to a beginning of the sliding process. The destination end 105 of the sliding portion 100 refers to a destination of the sliding process. In other words, when the user slides on the sliding portion 100 of the water sliding device, the user slides from the starting end 104 of the sliding portion 100 to the destination end 105 of the sliding portion 100.
In some embodiments, the first water pipe 201 may be disposed between a first lateral edge 106 and a second lateral edge 107 of the sliding portion 100. In this case, the sliding portion 100 can be divided into multiple sliding paths by the first water pipe 201. For example, in the embodiments shown in
In some embodiments, the first water pipe 201 may be disposed along the first lateral edge 106 or along the second lateral edge 107 of the sliding portion 100. That is to say, the first water pipe 201 may be disposed at an edge part of the sliding portion 100. For example, in the embodiment shown in
In some embodiments, a number of the first water pipe 201 may be set to be one. The one first water pipe 201 may be disposed between the first lateral edge 106 and the second lateral edge 107 of the sliding portion 100, so that the sliding portion 100 can be divided into two sliding paths (e.g., the first water pipe 201 shown in

The third inlet pipe 503 can be used to connect the first inlet pipe 501 and the inlet portion 402 of the water spray apparatus 400. Accordingly, when the first inlet pipe 501 communicates with the water source, water from the water source can flow into the water pipe 200 and the water spray apparatus 400 via the second inlet pipe 502 and the third inlet pipe 503, respectively.
In some embodiments, the third inlet pipe 503 and the inlet portion 402 may be detachably connected.
In some embodiments, the inlet portion 402 may be connected with the inlet of the water valve 404 via a first connecting water pipe 405.

Accordingly, by default, the pressure-regulating chamber 4047 is filled with water, a pressure inside the pressure-regulating chamber 4047 is greater than that outside the pressure-regulating chamber 4047, due to a pressure difference inside and outside the pressure-regulating chamber 4046, the movable valve plate 4046 can block the outlet passage 4044, the water valve 404 is in the closed state. In this circumstance, if the button 4042 is pressed, the button 4042 drives the movable part 40482 to move, so that the seal part 40481 can move to an opened position at which the drain hole 40451 is opened, water inside the pressure-regulating chamber 4047 can flow out via the drain hole 40451, the pressure inside the pressure-regulating chamber 4047 can decrease to a value that smaller than that of the pressure outside the pressure-regulating chamber 4047, due to the pressure difference inside and outside the pressure-regulating chamber 4047, the movable valve plate 4046 can move away from the outlet passage 4044 so as to open the outlet passage 4044, the water valve 404 switches to the opened state, the outlet portion 403 starts to spray water. In this circumstance, is the button 4042 is loosen, the movable part 40482 resets, the seal part 40481 returns to the closed position at which the drain hole 40451 is blocked, so that water from the water source can flow into the inlet passage 4043 and then flow into the pressure-regulating chamber 4047 via the water-inlet hole 40461, the pressure inside pressure-regulating chamber 4047 can gradually increase to a value that greater than that of the pressure outside the pressure-regulating chamber 4047, due to the pressure difference inside and outside the pressure-regulating chamber 4047, the movable valve plate 4046 can gradually move towards the outlet passage 4043, and after a predetermined period of time, the movable valve plate 4046 can move to block the outlet passage 4043, the water valve 404 returns to the closed state, the outlet portion 403 stops spraying water. Accordingly, when the button 4042 is pressed, the outlet portion 403 starts to spray water, and when the button 4042 is loosen, due to the pressure difference inside and outside the pressure-regulating chamber 4047, the water valve 404 can automatically return to the closed state after the predetermined period of time, so that the outlet portion 403 can automatically stop spraying water.
In some embodiments, a diameter of the drain hole 40451 may be greater than a diameter of the water-inlet hole 40461. By such a way, when the drain hole 40451 is opened, a volume of water flowing out from the pressure-regulating chamber 4047 is larger than that of water flowing into the pressure-regulating chamber 4047, the pressure inside the pressure-regulating chamber 4047 can decrease to a value smaller than that of the pressure outside the pressure-regulating chamber 4047, so that the movable valve plate 4046 can move away from the outlet passage 4044 to open the outlet passage 4044, thus the water valve 404 can switch to the opened state.
Although the present disclosure has been disclosed above with reference to preferred embodiments thereof, it should be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit or scope of the disclosure. Accordingly, the present disclosure covers changes and modifications made to the present disclosure that fall into scopes defined by the claims and equivalent technical solutions thereof.
