Water Purifier Valve {Valve of purified water dispenser}

The present invention relates to a valve opening and closing mechanism, and more particularly, to a leakage valve of a cold / hot water purifier, or a cock opening / closing mechanism installed in front of a water purifier so as to take hot water or cold water of a cold / hot water purifier.

Water purifiers or cold and hot water purifiers (hereinafter, referred to as water purifiers) that are widely used in homes are respectively provided with a predetermined leak valve to receive cold and hot water in front. The user can take cold water or hot water according to his choice.

1 is a perspective view showing a water purifier 1 widely used in the related art.

Although not shown, the valve is supported by the elastic force of the spring inside the housing to keep the outlet closed. The spring inside the housing is compressed or extended by a lever mechanism provided on the upper surface of the cap, and the valve is opened and closed by this movement.

Conventional valve opening and closing mechanism (2) has been developed in many ways to easily open and close the valve. That is, the illustrated method is a method in which the valve is opened and closed when the lever 3 is pushed forward or backward or pulled forward from the rear. In addition to this method, there is a method in which a lever is provided on the upper side of the valve housing and provided to move upward and downward. The valve opening and closing mechanism by spring and lever is widely used because of its ease of use or simple structure.

The valve opening and closing mechanism, which is opened and closed by only one simple operation, can receive the purified water easily, but it is also a risk factor for the infant. In other words, infants with a lot of curiosity and lack of judgment ability sometimes malfunctioned the hot water valves of the water purifier, resulting in burns of hot water. This is an accident that can occur because the operation of the valve coincides with the simple behavior of the child.

For this reason, conventionally, valve opening and closing means for preventing an unexpected accident have been proposed.

The proposed valve opening and closing means are generally provided with safety devices, ie locking means, separately. The locking means usually used is a method of preventing movement of the valve lever. The user should release the predetermined locking device for water intake and operate the valve lever. The locking device is installed over the valve housing and the valve lever to facilitate its release, but the additional cost of the device has been a factor that increases the manufacturing cost, or had a problem of inconvenience in use.

The purpose of the present invention for the above problems, to minimize the risk of burns due to the malfunction of the infant, to provide a water leakage valve opening and closing mechanism of the water purifier, which is convenient for the general public by a simple structure, the production cost is reduced. have.

The above object is a housing having a purified water inlet and a purified water outlet connected to the water purifier body; Valve means such as a packing for closing the inlet and outlet by elasticity of the spring; A water purifier leak valve comprising a lever means for opening and closing a valve means against an elasticity of a spring; The water purifier leak valve opening and closing mechanism is characterized in that the operation path of the lever means is rotatable.

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

Figure 2 is a perspective view of the water purifier leak valve opening and closing mechanism 10 according to an embodiment of the present invention, Figure 3 is an exploded perspective view.

The housing 12 has a water purifying inlet formed after being purified from the water purifier main body at the side, and has an elbow shape in which a discharge hole is formed downward, and a cap 14 for fixing the valve means is screwed on the upper side. The cap is provided with a through hole 18 so that the valve stem 16 penetrates through the center of the upper surface.

The valve means is provided by a packing 20 seated on the seating surface between the inlet and the outlet, a stem 16 fitted to the packing, a spring 22 supported between the bottom of the cap and the flange portion of the stem, and a pin. It consists of a lever 30 hinged to the top of the stem.

The lever 30, which is an opening and closing means, acts as a lever by using the upper surface of the cap as a support point in a hinged state with the upper end of the stem. The lever is composed of a locking plate 34 and a handle 36 for preventing rotation in the opposite direction to the rotating plate 32 which acts as a lever in contact with the upper surface of the cap. The rotating plate 32 is preferably supported in a state in which two identical plates are spaced apart from each other for balance. The shape of the handle 36 may be formed in the extended portion in the left and right directions to apply the same rotational force with less force, it may be modified in various forms. In addition, the locking plate 34 may not be installed such that the rotating plate 32 is rotatable in both the left and right directions, and may not be provided in the same shape so as to be symmetrical with the opposite side. By the illustrated configuration, the lever 30 is rotatable freely in contact with the upper surface of the cap 14, so that the right handed or left handed can be used without any inconvenience, but if it is possible to rotate in both directions in one position, the left handed or It can be used more conveniently regardless of right handedness.

4 is a cross-sectional view taken along the line A-A of FIG. 2 to more clearly show the operating state of the lever and the valve opening and closing mechanism.

The horizontal water purification inlet 41 and the vertical discharge port 42 are closed by the packing 20 supported by the spring 22 on the seat surface 43 formed on the upper surface of the discharge port. One side of the packing 20 is supported by the bottom surface 44 of the cap, while the other side is pressed by the seat surface 43 of the discharge port by the elastic force of the spring 22 supported on the upper surface of the flange 45 of the stem. It is maintained. The stem 16 is fitted so that the flange 45 'formed at the outer circumference of the stem 16 is prevented from being separated from the uneven groove formed in the packing 20, and the other end passes through the hole 18 of the cap and protrudes above the housing 12. do.

The rotating plate 32 of the lever is connected to the upper end of the stem 16 by the hinge means, and is also kept pressed against the top surface 46 of the cap by the spring. When the rotating plate 32 rotates in the direction of the arrow, the stem 16 is overcome by the rotating plate rotated about the hinge axis and lifted until one side 47 of the rotating plate contacts the upper surface 46 of the cap. Will be raised. Here, the bottom and one side of the rotating plate has an obtuse angle between them, and the boundary is rounded, so that the rotating plate is elastically slid by the spring and returned to its original position when the rotating force applied to the lever is removed. It also returns to its original position. Thus, the packing is to open or close the discharge port by the stem moving in the vertical direction.

One side 47 and the bottom surface 48 of the rotating plate may be provided at a right angle, not an inclination, that is, an obtuse angle. In this case, even if the rotational force applied to the lever 36 is removed, the rotating plate and the stem will not be returned to their original position, and again by applying a slight rotational force in the opposite direction. Thereby, there may be a convenience in not having to maintain a state in which a force is applied to the lever while taking water. On the other hand, the rotating plate is prevented from rotating in the counterclockwise direction by the locking plate 34 formed on the other side. As described above, the locking plate may be selectively provided to allow the lever to rotate in both directions.

Those skilled in the art may make various modifications without departing from the spirit of the present invention with reference to the disclosed embodiments. For example, as described above, the shape of the rotating plate or the lever may be changed in various shapes according to the purpose of use.

According to the present invention, since the water purifier valve opening / closing method is a method of rotating rather than simply pressing or pushing the lever, burns or water generated by the outflow of high-temperature water due to the mistake or curiosity of an infant. Waste can be prevented.

On the other hand, by having a simple structure than the valve opening and closing mechanism having a safety device developed by a concept similar to the present invention, the manufacturing cost is low, it can be easily used by the general public.
