DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0032] Referring to Figures 1-2 , the present application provides an embodiment: an automatic water replenishing device for a humidifier tank, comprising a tank 1, an upper portion of the tank 1 is provided with a liquid storage cylinder 2, an upper surface of the liquid storage cylinder 2 is fixedly connected with a water inlet pipe 3, sterile water can be replenished into the interior of the liquid storage cylinder 2 through the water inlet pipe 3, a bottom end of the liquid storage cylinder 2 is fixedly connected with a connecting pipe 4, an interior of the tank 1 is provided with a water replenishing pipe 5, upper and lower ends of the water replenishing pipe 5 are both provided in a tapered structure, the upper end of the water replenishing pipe 5 is fixedly connected with an interior top surface of the tank 1, and the bottom end of the connecting pipe 4 penetrates through the tank 1 and is inserted into the upper end of the water replenishing pipe 5. Referring to

[0033] , Figure 1 , Figure 3 and Figure 4 , a center of an interior bottom surface of the liquid storage cylinder 2 is fixedly connected with a vertical pipe 6, a top end of the connecting pipe 4 penetrates through the liquid storage cylinder 2, the top end of the connecting pipe 4 is fixedly connected with a bottom end of the vertical pipe 6, the sterile water entering into the interior of the liquid storage cylinder 2 can enter into the interior of the vertical pipe 6 through the upper end of the vertical pipe 6, and then enter into the water replenishing pipe 5 through the connecting pipe 4, the vertical pipe 6 is sleeved with an annular circular plate 7 outside, the inner and outer wall surfaces of the annular circular plate 7 are both fixedly connected with sealing rubber rings 8, the sealing rubber rings 8 can seal the gap between the outer side of the annular circular plate 7 and the inner wall of the liquid storage cylinder 2 and the outer wall of the vertical pipe 6, so that the sterile water entering into the interior of the liquid storage cylinder 2 can be completely blocked by the annular circular plate 7, avoiding the situation that the sterile water leaks below the annular circular plate 7.

[0034] The upper surface of the annular circular plate 7 is provided with a preheating unit, which comprises a heating plate 71 fixedly connected to the upper surface of the annular circular plate 7, and a heat-conducting rod 72 fixedly connected to the upper surface of the heating plate 71. The heating plate 71 can perform low-temperature heating on the sterile water located above the annular circular plate 7, thereby realizing preheating of the water flow and enabling the sterile water to be rapidly evaporated and humidified after entering the interior of the tank body 1, reducing the influence on the air pressure in the interior of the tank body 1, thereby avoiding causing discomfort to the patient. The heat-conducting rod 72 can increase the contact area with the water flow, thereby improving the heating effect on the water flow.

[0035] The bottom of the annular circular plate 7 is provided with an elastic unit, which comprises a telescopic rod 81 fixedly connected to the bottom surface of the annular circular plate 7, and a spring 82 sleeved outside the telescopic rod 81. The bottom ends of the telescopic rod 81 and the spring 82 are fixedly connected to the inner bottom surface of the liquid storage cylinder 2, and the upper end of the spring 82 is fixedly connected to the bottom surface of the annular circular plate 7. When the sterile water enters the interior of the liquid storage cylinder 2, the annular circular plate 7 can be extruded, so that the annular circular plate 7 moves downward, extrudes the telescopic rod 81 and the spring 82, and the spring 82 is compressed to generate elastic potential energy. When the annular circular plate 7 moves to the limit position of the telescopic rod 81 and the spring 82, the water supply is stopped. At this time, the water surface in the interior of the liquid storage cylinder 2 is slightly higher than the upper surface of the vertical pipe 6. If the sterile water overflows and enters the water replenishing pipe 5 in a small amount during the water supply process, a large impact force is avoided from being suddenly applied to the float, so that the float is not stuck in the water replenishing pipe 5 and the automatic water replenishing operation is affected. With the continuous water replenishing, the water flow in the interior of the liquid storage cylinder 2 is gradually reduced, and the pressure applied to the annular circular plate 7 is also reduced. In this process, the annular circular plate 7 can be continuously moved upward and reset under the action of the elastic potential energy of the spring 82, thereby continuously pushing the water flow upward, so that the water flow can continuously enter the vertical pipe 6 to complete the water replenishing operation. The bottom surface of the liquid storage cylinder 2 is provided with a through hole 83 penetrating through the liquid storage cylinder 2. The through hole 83 can avoid forming a sealed space below the annular circular plate 7, thereby avoiding hindering the movement of the annular circular plate 7 when the air below the annular circular plate 7 is extruded.

[0036] Referring to Figure 1 and Figure 5The inner part of the water replenishing pipe 5 is fixedly connected with a filter plate 9, a insertion hole 10 is arranged at the center of the upper surface of the filter plate 9, a connecting rod 11 is sleeved in the insertion hole 10, the upper and lower ends of the connecting rod 11 are fixedly connected with a float ball 12, a vertical rod 13 is fixedly connected to the outer wall surface of the connecting rod 11, the vertical rod 13 can reduce the contact area between the connecting rod 11 and the insertion hole 10, but still guides and limits the movement of the connecting rod 11, avoids the movement of the connecting rod 11 from deviating and being stuck, makes the movement of the connecting rod 11 and the float ball 12 more rapid and smooth, improves the water replenishing precision, the outer wall of the vertical rod 13 and the inner wall of the insertion hole 10 are matched with each other, a water outlet 14 is arranged on the outer wall surface of the water replenishing pipe 5, when the water surface in the tank body 1 is lower than the lower float ball 12, the float ball 12 can be on the lower side in the water replenishing pipe 5 under the action of gravity, so as to open the upper end of the water replenishing pipe 5, so that the water flow can enter the water replenishing pipe 5 through the connecting pipe 4, and then quickly enter the tank body 1 through the water outlet 14 to replenish water, with the water replenishing, the water flow in the tank body 1 will gradually rise, so that the float ball 12 is moved upward by the buoyancy, when the water surface in the tank body 1 rises to the required water level, the float ball 12 can be floated upward to block the upper end of the water replenishing pipe 5, and the water replenishing is stopped.

[0037] Working principle: sterile water is added to the liquid storage cylinder 2 through the water inlet pipe 3, the water flow can extrude the annular circular plate 7, so that the annular circular plate 7 moves downward and extrudes the telescopic rod 81 and the spring 82, so that the spring 82 is compressed to generate elastic potential energy, when the annular circular plate 7 cannot continue to move to the limit position of the telescopic rod 81 and the spring 82, the water adding is stopped, at this time, the water surface height in the liquid storage cylinder 2 is higher than the vertical pipe 6, a small amount of water flow can enter the vertical pipe 6 in the form of overflow during the water adding process, and then enters the water replenishing pipe 5 through the connecting pipe 4, so as to avoid that a large amount of water flow directly falls and impacts on the float, so that the float is stuck in the water replenishing pipe 5 and affects the water replenishing operation, with the gradual consumption and reduction of the sterile water in the tank body 1, the water surface moves downward, so as to drive the float ball 12 to move downward, so as to open the upper end of the water replenishing pipe 5, so that the water flow can enter the water replenishing pipe 5 through the connecting pipe 4, and then quickly enters the tank body 1 through the water outlet 14 to replenish water, at this time, the water surface rises, when the water surface in the tank body 1 rises to the required water level, the float ball 12 is floated to the upper end of the water replenishing pipe 5 to block it, so as to avoid that the gas in the tank body 1 after humidification is wasted after overflowing out of the water replenishing pipe 5.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
