[0021] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the description of the present invention with reference to the accompanying drawings is merely illustrative and not restrictive. Various embodiments can be combined with each other to form other embodiments not shown in the following description.
[0022] Please see Figures 1 to 4This utility model provides a horizontal water supply device, including a shell 1, a reel assembly 2, an inlet / outlet water assembly 3, a water supply connector 4, and a power assembly 5.
[0023] Specifically, the reel assembly 2 is located inside the housing 1. The reel assembly 2 includes a reel 21 and a limiting strip 22. The annular side of the reel 21 has a notch 211. One end of the limiting strip 22 is fixed to the reel 21, and the other end extends radially. In the vertical direction, the projections of at least two limiting strips 22 overlap, and the distance between the two limiting strips 22 is equal to the outer diameter of the water pipe (not shown in the figure). The inlet and outlet water assembly 3 includes an inlet and outlet water pipe 31 and a three-way valve 32. The three-way valve 32 is fixedly installed at the lower end of the inlet and outlet water pipe 31. The water pipe is wound around the reel 21, and the inner end of the water pipe passes through the notch 211 and communicates with the inlet and outlet water pipe 31. The outer end of the water pipe communicates with the water inlet connector 4, and in the vertical direction, the height of the outer end of the water pipe is higher than the height of the inner end of the water pipe.
[0024] The horizontal water supply device provided in this embodiment has a water pipe wound on a drum 21, with the inner end of the water pipe connected to the inlet / outlet water pipe 31 and the outer end of the water pipe connected to the water inlet connector 4. When water is added, water can flow out sequentially from the three-way valve 32, the inlet / outlet water pipe 31, the water pipe, and the water inlet connector 4. After the water is added, since the height of the outer end of the water pipe is much higher than the height of the inner end of the water pipe, the water in the water pipe can flow into the inlet / outlet water pipe 31 and the three-way valve 32 sequentially under the action of gravity, thereby realizing the automatic discharge of the water.
[0025] The housing 1 has a through hole, and a snap-fit component can be installed inside the through hole. The snap-fit component can prevent the water inlet connector 4 from entering the housing 1, thereby affecting its use. The user can directly pull the water inlet connector 4 outward to pull out the water inlet connector 4 and part of the water pipe. The water inlet connector 4 can be connected to the water inlet of the train's water tank, thereby realizing the addition of water to the train's water tank.
[0026] The three-way valve 32 can be connected to the inlet pipe, the drain pipe, and the inlet / outlet pipe 31 respectively. When water needs to be added, the three-way valve 32 connects the inlet pipe and the inlet / outlet pipe 31, so water can flow from the inlet pipe and the three-way valve 32 into the inlet / outlet pipe 31. After water is added, the three-way valve 32 connects the drain pipe and the inlet / outlet pipe 31, so the water remaining in the inlet / outlet pipe 31 can flow to the inlet / outlet pipe 31, the three-way valve 32, and the drain pipe under the action of gravity, thereby realizing automatic drainage.
[0027] Crucially, multiple limiting strips 22 are provided, with at least two limiting strips 22 arranged at intervals in the vertical direction. The distance between these two limiting strips 22 is equal to the outer diameter of the water pipe. Therefore, when the water pipe is wound onto the reel 21, due to the restraining effect of the limiting strips 22, the water pipe is arranged in a single-layer winding manner, i.e., there is only one layer of water pipe in the vertical direction. The water pipe arranged in this way will not twist and will not overlap in the vertical direction, thus not affecting the automatic drainage of accumulated water.
[0028] It can be assumed that the drum 21 is roughly cylindrical, therefore the diameter direction of the drum 21 is defined as radial. In addition, the vertical direction is parallel to the axis of the drum 21.
[0029] The height of the limiting strip 22 on the side away from the drum 21 is higher than the height of the limiting strip 22 on the side close to the drum 21.
[0030] It can be imagined that the water pipe is located between the upper and lower limiting strips 22. Since the outer radial side of the limiting strip 22 is higher and the inner radial side is lower, the water pipe on the outer radial side is also higher and the water pipe on the inner radial side is lower. Due to the height difference, the water remaining in the water pipe can automatically flow into the inlet and outlet water pipes 31 due to gravity.
[0031] The drum 21 also includes a buffer surface 212 disposed at the notch 211, the buffer surface 212 being disposed at an angle to the annular side surface of the drum 21.
[0032] The inlet and outlet water pipe 31 is provided with an inlet and outlet water interface 311, which is connected to the inner end of the water pipe; the inlet and outlet water interface 311 is set at an acute angle to the buffer surface 212.
[0033] The water pipe is a flexible pipe, and the inlet / outlet interface 311 can extend radially along the drum 21. Therefore, the angle between the inlet / outlet interface 311 and the annular side of the drum 21 is a right angle. Since the angle is relatively large, if the water pipe directly contacts the annular side of the drum 21 during winding, this part of the pipe is prone to significant bending, thus affecting the normal flow of water. To avoid this problem, a buffer surface 212 is provided at the notch 211. The angle between the buffer surface 212 and the inlet / outlet interface 311 and the water pipe is small, resulting in less bending between the water pipe and the buffer surface 212, thus facilitating the normal flow of water.
[0034] In order to enable the drum 21 to rotate normally, the inlet and outlet water pipes 31 are coaxially arranged with the drum 21, and the drum 21 is rotatably sleeved on the outside of the inlet and outlet water pipes 31. That is to say, the inlet and outlet water pipes 31 can be fixed inside the housing 1, and the drum 21 can rotate with the inlet and outlet water pipes 31 as the center.
[0035] The reel assembly 2 also includes an upper outer plate 23 and a lower outer plate 24. The upper outer plate 23 is fixed to the upper end face of the reel 21, and the lower outer plate 24 is fixed to the lower end face of the reel 21. Part of the limiting strip 22 is fixed to the upper outer plate 23, and another part of the limiting strip 22 is fixed to the lower outer plate 24.
[0036] Along the vertical direction, the upper outer plate 23 and the lower outer plate 24 are spaced apart, and a space for the water supply pipe to be wound is provided between the upper outer plate 23 and the lower outer plate 24. The limiting strip 22 can also act as a reinforcing rib to enhance the structural strength of the installation of the upper outer plate 23 and the lower outer plate 24.
[0037] The power component 5 can be installed inside the housing 1, and the power component 5 may include a motor, gear set, etc. The power component 5 can drive the drum 21 to rotate, thereby realizing the winding of the water pipe.
[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
