Here comes the great convenience. Looking at the existing water level control devices for drinking fountains and water boilers, most of them are divided into lever type water level control devices or longitudinal direct drive type water level control devices. The other end of the lever swings in the opposite direction so that the corresponding water supply mechanism stops water supply, which makes the horizontal dimension of the water level control device too large, resulting in the water tank often being made into a wide and flat structure, which is bulky and heavy, such as Chinese patent ZL03274379.3 A disclosed automatic water level control device discloses this technical solution; the latter described longitudinal direct-drive water level control device is an improvement on the lever type water level control device, and a vertical rod is arranged above the float, There is a sealing plug on the upper end of the vertical rod, and the float drives the vertical rod to block the corresponding water inlet position to achieve the purpose of water stop.

The sealing end 151 is pressed against the water storage tank 1 by the water body to seal the water storage tank 1, and when the water pressure self-locking water inlet valve 15 is pushed up, so that the sealing end 151 leaves the water tank, the water is released from the water inlet tank 152 flow out.

The present invention is based on the conventional vertical direct-drive water level control device and improves the technical structure disclosed in No. 200810145390.6. There is a concave cavity 5 on the float 3, and an upward convex cavity is arranged in the concave cavity 5. The guide cylinder 6, the upwardly protruding guide cylinder 6 and the float 3 are an integrated structure, the upwardly protruding guide cylinder 6 is equipped with a sealing plug 7 for sealing the water inlet hole 4, and the lower part of the water inlet support plate 2 is provided with an outer sleeve on the upper The limit sleeve 8 on the outer periphery of the protruding guide cylinder 6, the limit sleeve 8 and the water inlet support plate 2 are an integrated structure, as shown in Fig. 4, Fig. 5 and Fig. 6 . The float 3 is designed to have a structure with a concave cavity 5, and the convex guide cylinder 6 and the sealing plug 7 are all embedded in the float 3, so that the water level controller can be made into an ultra-thin structure, and at the same time, the convex guide The barrel 6 floats up and down in the limit sleeve 8 to realize the lateral limit of the float 3 . For the ultra-thin water level control device of the present invention, a guide cavity 9 is provided at the bottom of the raised guide cylinder 6, and a guide column 10 matched with the guide cavity 9 is provided on the water storage tank 1, and the guide column 10 can further guide the float. 3 play the role of longitudinal guidance and lateral limitation, as shown in Figure 4.

Furthermore, the limit sleeve 8 is arranged below the water inlet hole 4, and, during the specific preparation process of the ultra-thin water level control device for the above-mentioned water dispenser and water boiler, the limit sleeve 8 surrounds the On the outer periphery of the water inlet 4, a limit sleeve 8 is arranged coaxially with the water inlet 4, as shown in FIG. 5 .

In the ultra-thin water level control device for water dispenser and water boiler described in the present invention, there is a water inlet gap for connecting the water inlet hole 4 with the water storage tank 1 between the limit sleeve 8 and the upwardly convex guide cylinder 6. 11. Further, in order to facilitate the water flow to the lower cavity of the water storage tank 1 in time so that the float 3 can receive the buoyancy of the water body in a timely and accurate manner, the bottom wall of the concave cavity 5 is provided for connecting the water inlet gap 11 with the water body. The water outlet hole 12 connected to the lower cavity of the water storage tank 1 is shown in FIG. 6 .

When the water supply tank 16 is placed on the water inlet support plate 2, the upper pressure inlet cylinder 13 presses against the bottom of the hydraulic self-locking water inlet valve 15, so that the sealing end 151 leaves the water tank, and the water body flows out from the water inlet tank 152. In the meantime, in order to simplify the structure, in the specific structure of the ultra-thin water level control device for the above water dispenser and water boiler, the upper pressure water inlet cylinder 13 surrounds the outer periphery of the water inlet hole 4, and the limit sleeve 8 is the same as the water inlet hole 4. axis settings.

Besides this embodiment, the sealing plug 7 can also be a flat cake-shaped structure.

When the present invention is installed on the water dispenser and the water boiler for use, what Fig. 7 and Fig. 8 show is that the present invention is in the state of water intake. In the free state of the water supply tank 16, the water pressure self-locking water inlet valve 15 is under the force of the water pressure, and the water body of the sealing end 151 is pressed against the water storage tank 1 to seal the water storage tank 1. When the water supply tank 16 is placed on the water inlet support plate 2, the upper pressure inlet cylinder 13 is pressed against the bottom of the hydraulic self-locking water inlet valve 15, so that the sealing end 151 leaves the water tank, and the water body flows in from the water inlet tank 152 into the upper pressure inlet cylinder 13, then flows out from the water inlet hole 4 to the limit sleeve 8, and then flows from the limit sleeve 8 through the water inlet gap 11, and the water flowing out from the water inlet gap 11 is then passed by the lower part of the float 3 The water outlet hole 12 of the concave cavity flows to the bottom of the water storage tank 1 . During this period, the water volume in the water storage tank 1 has not yet reached the upper limit, and the buoyancy of the water volume to the float 3 is not large enough, so the sealing plug 7 on the float 3 is separated from the water inlet hole 4 on the water inlet support plate 2, that is, the water inlet hole 4 is opened. In the open state, the water flow of the water supply tank 16 continuously flows into the water storage tank 1 .

When the water volume of the water storage tank 1 reaches the upper limit, as shown in Figure 9 and Figure 10, the buoyancy force on the float 3 is large enough, and the float 3 moves along the limit sleeve 8 on the water inlet support plate 2 and the water storage tank 1 The guide column 10 on the top floats up, and the sealing plug 7 can block the water inlet 4, and the water in the water supply tank 16 can no longer flow into the water storage tank 1, thereby realizing the limitation of the water level in the water storage tank 1 and avoiding any supply to the user. Drinking water is flowing and the water pressure is too high.

During the use of water dispensers and water boilers, when the user releases the water in the water storage tank 1 through the water outlet pipe 14, at this time, the water output in the water storage tank 1 decreases, and the buoyancy of the float 3 decreases along the water inlet. The limit sleeve 8 on the support plate 2 and the guide column 10 on the water storage tank 1 move down, the sealing plug 7 leaves the water inlet 4 again, and the water body of the water supply tank 16 flows through the water inlet 4 to the water storage tank 1 again. Replenishment, so that the water storage tank 1 is kept at the preset water level at all times, so as to ensure sufficient water supply to the user.

By circulating in this way, the precise control of the water level of the water storage tank 1 is realized.

When the water supply tank 16 is moved away from the water inlet support plate 2, the water pressure self-locking water inlet valve 15 immediately breaks away from the top pressure and falls rapidly, and the sealing end 151 is pressed down immediately by the water pressure to seal the water supply. tank 16, so that water will not leak even though the water supply tank 16 is removed.

In summary, the ultra-thin water level control device for water dispensers and water boilers according to the present invention changes the float 3 into a structure with a concave cavity 5, so that the convex guide cylinder 6 and the sealing plug 7 are embedded In the float 3, the water level controller can be made into an ultra-thin structure, which greatly reduces the overall volume of the water level controller and the water storage tank 1, so that it can realize a light, small and flexible structure; 2. The lower part is equipped with a limit sleeve 8 that covers the outer periphery of the upward convex guide cylinder 6, so as to realize the lateral limit of the float 3, and avoid the displacement of the sealing plug 7 due to the left and right floating of the float 3, which cannot seal the water. phenomenon, the sealing plug 7 can accurately seal the water inlet hole 4 on the water inlet support plate 2, and realize precise control of the water level; the invention has an ultra-thin structure, precise water level control, very flexible and simple product structure, and convenient preparation.
