Detailed ways

To further illustrate the various embodiments, the present invention is provided with the accompanying drawings. These drawings are a part of the disclosure of the present invention, which are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant description of the specification to explain the operation principles of the embodiments. With reference to these contents, one of ordinary skill in the art will understand other possible embodiments and advantages of the present invention. Components in the figures are not drawn to scale, and similar component symbols are often used to represent similar components.

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

As shown in FIG. 1 and FIG. 2, an automatic water filler includes a water addition tank 10, a water storage tank 20 and a water level control device 30. The water addition tank 10 is located above the water storage tank 20, and the top and bottom of the water tank are respectively provided with water filling ports 12 and the water outlet 14, a water level control device 30 is provided on the water outlet, and the water level control device includes a hollow cavity valve body 32, a valve core 34 and a float 36, and the water inlet 320 at the upper end of the valve body 32 is connected to the water tank. The water outlet 14 is connected to each other, and the water outlet 322 at the lower end of the valve body extends into the water storage tank 20; In sealing cooperation with the water inlet of the valve body, the bottom of the valve core extends out of the valve body, the bottom of the valve core is connected with an elastic body 40 , and the other end of the elastic body is connected with the float 36 . The elastic body is one of a compression spring, a compressible elastic rubber, and a compressible elastic sheet, and the following embodiments use a compression spring for description.

Referring to FIGS. 1 to 4 , the connection between the compression spring 40 and the valve core is located at the center of the bottom of the valve core, and the connection between the spring and the float is located on the central axis of the top surface of the float. During the descending process, when the spring is in a normal tension or compression state, there will be no distortion, so the force of the float on the valve core is greater, so the force of the valve core on the valve body is also stronger, and it is easier to achieve this. The effect of automatic water addition and stop water addition of the automatic water dispenser. As shown in Figure 1-Figure 4, the float and the valve core are connected by lever, the connection between the spring and the float is not in the middle of the float, but on the right side of the float, so the force of the float on the valve core is more due to the lever factor. large, so it is easier to drive the rise and fall of the spool. Preferably, an extension column 16 is added on the bottom surface of the water filling tank 10 , the extension length of the extension column 16 is greater than the length of the valve body, a connecting rod is connected to the bottom of the extension column 16 , and one end of the connecting rod is hinged to the extension column 16 The other end is fixed on the float 36, the connection point between the connecting rod and the float is located on the central axis of the float, and the hinge point between the connecting rod and the extension column is located on the extension line of the central axis of the float, so the float pair The force of the spool always acts on the center of the spool, so when the spool moves up or down with the float on the valve body, it always moves in its vertical direction without deflection or inclination. In order to increase the contact area between the valve core and the valve body and enhance the sealing effect, the surface of the valve core and the water inlet of the valve body sealingly matched is a conical surface, and the top of the valve core is a conical surface.

3 and 4, preferably, when the valve core 34 blocks the water inlet of the valve body 32, the spring is in a compressed state. When adding water to the water tank 10, due to the low water level of the water storage tank, the float naturally sags due to the action of gravity, the valve core does not block the valve body, and the water flows into the water storage tank along the direction of the arrow in Figure 3; As the water level gradually rises, the float also gradually rises with the water level, driving the valve core to rise. When water is added, the water continuously flows into the water storage tank 20 from the high water outlet 322 of the valve body, and the float will With the change of the water surface, it will continue to shake. At this time, due to the existence of the compression spring, the elastic force of the compression spring will absorb the vibration of the water, so that the spool is in a stable state, and will not oscillate with the float. And the valve body will not be in a state of friction all the time, which increases the sealing performance and service life of the valve core and the valve body.

Referring to Figure 4, when there is no compression spring and the float is directly connected to the valve core, when the water level is added to the water level position II, the top surface of the valve core is sealed with the valve body, and no water is added. However, in the automatic water filler in this application, a compression spring is directly connected to the float and the valve core. Due to the reaction force generated by the continuous compression of the compression spring, when the water level in the water storage tank reaches the water level position I, it is higher than the water level when there is no spring. Only position II valve core will block the valve body, and how much it is higher than the water level can be adjusted by adjusting the elasticity of the spring. Similarly, when the water in the water storage tank is consumed, due to the reaction force generated by the compression of the spring, only after the amount of water level drop exceeds the water level position II, the valve core will be separated from the valve body, and then start adding water. As long as the existing automatic water filler consumes a very small part of the water in the water storage tank, it will start to add water automatically, and then stop adding water after adding a small amount of water, so when the humidifier is working, the valve core will continue to rise and The contact surface of the valve core and the valve body is continuously rubbed, which reduces the sealing effect and shortens the service life; and the automatic water filler provided by the present invention will start to automatically add water when the water level drops to a certain extent, not so frequent, thus providing the service life of the spool.

Referring to Figure 5, since the float is located under the water outlet of the valve body, when adding water, the water will always impact the float, which will increase the burden of the compression spring. In order to reduce the impact of water on the float, the float is located in the valve body. There is also a water passage 360 directly below the water outlet of the sump. When adding water, the water will enter the water storage tank through the water passage 360, and will not directly impact the float, so the float is in a relatively stable state and will not Affects the compression spring.

The present invention also provides an upper water-filling type humidifier, and the automatic water-filler of the humidifier is the above-mentioned automatic water-filler.

Although the present invention has been particularly shown and described in connection with preferred embodiments, it will be understood by those skilled in the art that changes in form and detail may be made to the present invention without departing from the spirit and scope of the invention as defined by the appended claims. Various changes are made within the protection scope of the present invention.
