The present invention relates to a backflow preventing device of the humidifier water tank, and more particularly, has a blocking shaft coupled to the top of both sides of the water gate of the space to control the water to flow in only one direction through the water gate, The present invention relates to a device for preventing backflow of a humidifier water tank which prevents water from flowing back into the water tank or diffuses hot air into the water tank.

Research shows that when the relative humidity reaches 55%, the bacteria can hardly reproduce, and if the relative humidity is above 65%, the person may feel uncomfortable breathing or mucous membranes, or may be less immune, and the relative humidity may be less than 20%. In this case, the air becomes excessively dry, causing the human skin, mouth and lips to dry. Indeed, in excessively dry air, suspended particles and dust increase the incidence of various diseases, such as asthma, emphysema or bronchitis.

In addition, dry air can generate static electricity anywhere, making you feel uncomfortable and dizzy, and dry air quickly causes new furniture, new books, or other items to wear out quickly. In continental climatic regions, indoor humidities in winter are about 20% RH, far below the average of 40 to 70% RH, so a good humidifier should serve to keep the indoor humidity at an average.

In terms of function, humidifiers are classified into three types: (a) electric heating-type, (b) ultrasonic wave type, and (c) atomizing-type. Electric heating humidifiers, most commonly used, also called vaporizing-type humidifiers, are simple in structure, low in cost, and excellent in efficiency. Each of these three types of humidifiers consists of a housing, a water tank, a nozzle and a water supply means. The water tank is installed inside the housing to store water, and is provided with a heater for heating the water in the water tank to evaporate it into water vapor so as to discharge the water vapor through the nozzle installed above the water tank. The housing is perforated at its end with a water inlet connected to a water supply means, which may be a sealed container for receiving water. After all the water in the water supply means is used, the water supply means can be separated to replace or to replenish the water therein.

As shown in FIG. 6, the conventional humidifier 9 includes a water supply means 91, a space portion 92, a water gate 93, and a water tank 94. The water inside the water supply means 91 continues to flow into the water tank 94 to reach a certain level. However, after the water in the water tank 94 is heated by a heater (not shown), the water temperature in the water tank 94 will be raised to 80 ~ 100 ℃. In this case, if the water is not controlled to flow into the water tank 94, the water level inside the water tank 94 will rise up to the space 92 and the water outlet of the water supply means 91. As a result, the space portion 92 and the water supply means 91 encounter high temperature water flowing back from the water tank 94 and deteriorate or melt when severe.

On the other hand, if there is no water in both the water supply means 91 and the space 92, the water vapor generated in the water tank 94 is continuously diffused into the space 92 and the water supply means 91 It will damage them.

Accordingly, the present invention is devised to solve the conventional problems as described above, the object of the present invention is to provide a backflow prevention device of the humidifier water tank that can prevent the backflow of water or steam in the humidifier water tank. It is.

The present invention for achieving the above object includes a housing, a water tank, a nozzle and a water supply means. The water tank is installed inside the housing to store water, and the water inside the water tank is converted into water vapor and discharged to the outside through a nozzle installed at the top of the water tank. The upper surface of the housing is perforated with a water inlet coupled to the water supply means, and a space is formed between the water supply means and the water tank, and a water gate through which water passes is provided. A barrier plate of the same size as the water gate is rotationally coupled to the outer end of the space to seal the water gate. From this configuration, the present invention allows the water to flow in only one direction through the water gate into the water tank, thereby preventing the water in the water tank from flowing back.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

Preferred embodiment of the backflow prevention device of the humidifier water tank according to the present invention, as shown in Figures 1 to 5, the housing 2, the water tank 3, the nozzle 4 and the water supply means (5) It includes.

The housing 2 is composed of a base member 21 and an upper cover 22. The cover 22 is formed with a cover 221 in which a plurality of vent holes 2211 are perforated in the cover 22 so that water vapor passes through the nozzle 4 and is discharged to the outside of the nozzle 4. 4). In addition, the water inlet 23 is coupled to the water supply means 5 on the upper surface of the housing 2.

The water tank 3 is provided inside the housing 2, and the water in the water tank 3 can be changed into water vapor by a heater, a supersonic wave oscillator or an atomizer, and the changed water vapor It is discharged to the outside through the nozzle (4).

The nozzle 4 installed above the water tank 3 for discharging water vapor may be connected to a flexible pipe (not shown) that transfers the steam to a remote location for use in facial making or for disinfection. Can be.

A space portion 24 is formed between the water supply means 5 and the water tank 3, and the water portion 25 is provided with a water gate 25 through which water passes, and at the outer end of the space portion 24, a water gate ( In order to seal 25, a blocking plate 6 of the same size as the water gate 25 is assembled. The upper end of the blocking plate 6 is fixed to a pivot rod 61 rotatably coupled to both upper ends of the sluice 25 (hereinafter referred to as a rotational shaft coupling), and the lower end of the blocking plate 6 is connected to the sluice 25. It is provided in a state suspended in the air to operate in close contact with the stepped portion 251 located on the lower side. Thus, water flows in only one direction through the water gate 25 and can be introduced into the water tank 3, and water can be prevented from flowing back inside the water tank 3. In addition, the stepped portion 251 located at the lower end of the water gate 25 may be in close contact with the blocking plate 6 to seal the water gate 35.

The blocking plate 6 is light, resistant to damage, and set to rotate at a predetermined angle. When the water supplied by the water supply means 5 flows through the water gate 25, the blocking plate 6 is rotated in a limited manner so that water flows into the water tank 3 so as to open only about 1 mm to 2 mm. In this way, the blocking plate 6 is completely rotated to prevent the opening and the water blocking action is released. When the water level of the water tank 3 rises to the blocking plate 6, the blocking plate 6 is pushed by the water pressure to be in close contact with the step 251, and the water gate 25 is sealed. At this time, the water of the water supply means 5 can no longer flow into the water tank 3, and the water in the water tank 3 can not flow back into the space 24. In such a configuration, water can be supplied continuously, and it is possible to prevent the hot water or the hot steam from spreading inside the water tank 3.

Although the above has been described with reference to the embodiments of the present invention, the present invention may be modified in various forms within the scope of the technical idea of the present invention described in the claims below.

As described above, the present invention is provided with a blocking plate to seal the surface by close contact with the water gate, so that the water of the water supply means can no longer flow into the water tank, and the water inside the water tank cannot flow back into the space portion. Water can continue to be supplied, preventing hot water or hot steam from spreading inside the water tank, i.e. controlling the water to flow in the water tank in only one direction by means of a barrier plate, It is effective to prevent backflow.
