Example 2

Based on the above embodiment, as shown in fig. 4, embodiment 2 of the present application is different from embodiment 1 in the connection manner of the control box 1 and the water storage tank 4, and the control box 1 is rotatably connected to the opening side of the water storage tank 4. Specifically, the extension pipe 9 includes a hose portion 91, a first hard pipe portion 92, and a second hard pipe portion 93 integrally connected in order, the hose portion 91 is a metal pipe or plastic pipe having flexibility, the first hard pipe portion 92 is used for connecting the hose portion 91 and the second hard pipe portion 93, and the first hard pipe portion 92 and the second hard pipe portion 93 are hard metal pipes or plastic pipes. One end of the hose portion 91 is fitted over one end of the water inlet pipe 31 located inside the water storage tank 4, and connection between the hose portion 91 and the water storage tank 4 is achieved by friction force. Meanwhile, since the hose portion 91 has flexibility, the angle between the hose portion 91 and the control box 1 can be changed when the hose portion 91 is subjected to an external force. The included angle between the first hard tube portion 92 and the second hard tube is an obtuse angle, and the specific included angle between the first hard tube portion 92 and the second hard tube portion is 120-150 degrees. The nip formed by the first hard tube portion 92 and the second hard tube portion 93 is oriented toward the rotational axis of the control box 1.

The bottom of the water storage tank 4 is also fixedly provided with a cylinder 10, a piston rod of the cylinder 10 penetrates through the bottom of the water storage tank 4 and is rotationally connected with one end, far away from the hose portion 91, of the second hard pipe portion 93, the piston rod stretches and contracts along the height direction of the water storage tank 4, and the cylinder 10 is used for controlling the extension pipe 9 to move along the height direction of the water storage tank 4. When the control box 1 is arranged on the opening of the water storage tank 4 in a covering manner, the included angle between the piston rod of the air cylinder 10 and the second hard pipe portion 93 is an obtuse angle.

When the piston rod of the cylinder 10 is extended, the piston rod directly acts on the second hard tube portion 93 to indirectly control the movement of the extension tube 9 in a bottom direction away from the water storage tank 4. In the moving process of the extension pipe 9, as the piston rod is rotationally connected with the second hard pipe part 93, the direct included angle between the piston rod and the second hard pipe part 93 can be changed; meanwhile, the hose portion 91 has flexibility, so that the included angle between the first hard tube portion 92 and the control box 1 can be changed; the control box 1 receives the effort of extension pipe 9 for control box 1 takes place relative rotation with storage water tank 4, and the opening of storage water tank 4 is opened, and then conveniently adds hot water or cold water in the storage water tank 4.

The included angle between the first hard pipe 92 and the second hard pipe 93 is set between 120 ° and 150 °, on one hand, one function of the extension pipe 9 is to lengthen (to send water near the bottom of the water tank 4 into the water inlet pipe 31), since the depth of the water tank 4 is fixed, if the included angle between the first hard pipe 92 and the second hard pipe 93 is too small, the whole length of the extension pipe 9 is too long, and the material consumption is more. If the angle between the first hard tube portion 92 and the second hard tube portion 93 is too large, in the initial state (the control box 1 is covered on the water storage tank 4), the angle between the piston rod and the second hard tube portion 93 approaches a flat angle, resulting in poor rotation of the piston rod and the second hard tube portion 93.

On the other hand, the other function of the extension pipe 9 is a supporting function, in the process of controlling the extension pipe 9 to gradually move in the opening direction of the water storage tank 4, the piston rod transmits the external force to the second hard pipe portion 93, the external force is transmitted to the first hard pipe portion 92 again, and finally the first hard pipe portion 92 acts on the control box 1, so that the control box 1 rotates. If the included angle between the first hard tube portion 92 and the second hard tube portion 93 is too small, the force component of the first hard tube portion 92 acting on the control box 1 is small by performing the force analysis, and at this time, the first hard tube portion 92 cannot drive the control box 1 to rotate. If the angle between the first hard pipe portion 92 and the second hard pipe portion 93 is too large, in the initial state (the control box 1 is capped on the water storage tank 4), the angle between the first hard pipe portion 92 and the control box 1 is nearly right angle, resulting in that rotation between the hose portion 91 and the control box 1 is not easy to occur.

Optionally, please refer to fig. 4 and 5, according to some embodiments of the present application. The water storage tank 4 is also provided with a first sealing ring 11, and the first sealing ring 11 is arranged at the position where the piston rod passes through the water storage tank 4; specifically, a first mounting groove 12 is formed in the bottom wall of the water storage tank 4, and a first sealing ring 11 is embedded in the first mounting groove 12. Because the piston rod of the air cylinder 10 needs to pass through the water storage tank 4, the sealing performance of the position where the piston rod passes through can be increased by additionally arranging the first sealing ring 11, and the possibility of water leakage in the water storage tank 4 is reduced.

Because the piston rod can relatively move with the first sealing ring 11 (the first sealing ring 11 is not moved) in the telescopic process, at this time, a friction force exists between the first sealing ring 11 and the piston rod, and the friction force easily causes the first sealing ring 11 to be separated from the first mounting groove 12. Thus, the piston rod is respectively provided with a fixed block 13 and a first compression spring 14, and the fixed block 13 is positioned outside the water storage tank 4 and fixedly connected to the piston rod; the first compression spring 14 is sleeved on the piston rod, one end of the first compression spring 14 is connected with the first sealing ring 11, and the other end of the first compression spring is fixedly connected with the fixed block 13.

When the piston rod stretches, the fixed block 13 moves along the direction close to the bottom of the water storage tank 4, so that the first compression spring 14 is compressed, and under the elastic restoring force of the first compression spring 14, the first compression spring 14 can generate pressure on the first sealing ring 11, so that the stability of connection between the first sealing ring 11 and the water storage tank 4 is improved, and the possibility that the first sealing ring 11 falls off is reduced. In the process of gradually contracting the piston rod and recovering to the initial state, the first compression spring 14 always has an elastic pressure acting on the first sealing ring 11, and the elastic pressure is always opposite to the contracting direction of the piston rod, so that the first sealing ring 11 can be always pressed on the water storage tank 4, and the pressure gradually decreases and finally becomes 0.

In addition, referring to fig. 6, a second mounting groove 18 is further formed in the inner wall of the water storage tank 4, and a second sealing ring 17 is embedded in the second mounting groove 18, and the second sealing ring 17 is also installed at a position where the piston rod passes through the water storage tank 4 and is located above the first sealing ring 11.

The second sealing ring 17 can play a sealing role for the water storage tank 4, when the piston rod stretches, the piston rod and the second sealing ring 17 can move relatively, and the second sealing ring 17 has a trend of moving along with the piston rod. The second return spring will exert a downward force on the second sealing ring 17 to improve the stability of the second sealing ring 17 in the water storage tank 4.
