DESC:TECHNICAL FIELD
The present invention generally relate to water purifiers, and more particularly, to an apparatus for cutting off water flow in the water purifier for preventing water overflow from a storage tank when water level reaches a maximum water level in the storage tank.

BACKGROUND
Conventional water purifiers include purification devices and a storage tank for storing the purified water. Conventional water purifiers include a water-level control system in order to detect and control the water level in the storage tank. The water-level control system uses water level indicators or sensors, for example, conductivity and weight sensors, and one or more solenoid valves. When the water level in the storage tank reaches to a maximum level, the solenoid valves can control the water flow into the storage tank. The water level indicators or sensors can actuate the solenoid valves, and/or other electric controls at preset water levels. Therefore, it is important for these indicators or sensors to be reliable.
However, if any one of components of the water-level control system is faulty or malfunctioning, the water level information may not be correct. As a result, the water may overflow from the storage tank of the water purifier. Additionally, a control circuit is needed for the solenoid valves and water level indicators or sensors in order to control the water flow when the water level reaches its maximum level. Therefore, the water-level control system used in the conventional water purifiers is expensive for the customer, and requires repairs, maintenance and replacement over time.

OBJECTS
The principal object of embodiments herein is to provide an apparatus for cutting off water flow in the water purifier for preventing water overflow from a storage tank when water level reaches a maximum water level in the storage tank.
Another object of embodiments herein is to prevent water flow to water purification cartridges thereby preventing water flow to storage tank once the water has reached the maximum water level in the storage tank of the water purifier.
Another object of embodiments herein is to eliminate the need for a water-level control system that uses water level indicators or sensors, for example, conductivity and weight sensors, and one or more solenoid valves for detecting and controlling the water level in the storage tank of the water purifier.
Another object of embodiments herein is to provide a mechanical type water flow cut off apparatus for the water purifier, which is durable and reliable and is inexpensive.

Further, the first water purification cartridge (14) defines a water outlet port (14B) which is in fluid communication with a water inlet port (104) of the apparatus (100) through a discharge line (1). In an embodiment herein, the second water purification cartridge (16) defines a water inlet port (16A) which is in fluid communication with a water outlet port (106) of the water flow cut-off apparatus (100) through the discharge line (2).
In an embodiment herein, the third water purification cartridge (22) defines a water inlet port (22A) in fluid communication with a water outlet port (16B) of the second purification cartridge (16) via the discharge line (3) through a pump (18) and a mechanical pressure switch (20). In an embodiment herein, the fourth water purification cartridge (28) defines a water inlet port (28A) in fluid communication with a water outlet port (22B) of the third water purification cartridge (22) via a discharge line (4) through a split valve (24). In an embodiment herein, the fifth water purification cartridge (30) defines a water inlet port (30A) which is in fluid communication with a water outlet port (22B) of the third water purification cartridge (22) via a discharge line (5) through the split valve (24) and a modulator (26).
In an embodiment herein, the sixth water purification cartridge (34) defines a water inlet port (34A) which is in fluid communication with a water outlet ports (28B, 30B) of the fourth and fifth water purification cartridges (30) through the discharge lines (6, 7) respectively via a split valve (32). In one embodiment herein, the seventh water purification cartridge (36) defines a water inlet port (36A) which is in fluid communication with a water outlet port (34B) of the sixth water purification cartridge (34) via the discharge line (8). The seventh water purification cartridge (36) defines a water outlet port (36B) which is in fluid communication with the storage tank (38) through the discharge line (9) for discharging the purified water into the storage tank (38).
FIG. 2 depicts a detail A of the water flow cut off apparatus (100), according to embodiments as disclosed herein. In one embodiment herein, the water flow cut off apparatus (100) is adapted to prevent water flow to water purification cartridges (16, 22, 28, 30, 34 & 36) thereby preventing water flow to storage tank (38) once the water has reached the maximum water level in the storage tank (38) of the water purifier (10). In one embodiment herein, the water flow cut off apparatus (100) includes a float (102), a float support member (104), a housing (106), a valve spool (108), a seal member (110), a water inlet port (114) and a water outlet port (116).
In an embodiment, the float (102) is configured to move up and down according to the water level in the storage tank (38). The float (102) is supported on the float support member (104). The valve spool (108) is positioned within the housing (106) and is configured to slide within the housing (106) to one of allow or restrict water flow to the water outlet port (116) of the apparatus (100) according to the movements of the float (102) in the storage tank (38). In one embodiment, the water inlet port (114) is in fluid communication with the water outlet port (14B) of the first purification cartridge (14) through the discharge line (1). The water outlet port (116) is in fluid communication with the water inlet port (16A) of the second water purification cartridge (16) through the discharge line (2).
The float (102) rises up in the storage tank (38) thereby moving the valve spool (108) to a closed position thereby restricting water from the water inlet port (114) to the water outlet port (116) when the water level in the storage tank (38) reaches to a maximum level. Thus, preventing the water flow to the water purification cartridges (16, 22, 28, 30, 34, 36) which in turn results in preventing water flow to the storage tank (38) once the water level has reached to the maximum level.
When the float (102) rises in the storage tank (38), the valve spool member (108) moves to a closed position in which the seal member (110) blocks water flow to the water outlet port (116), thereby preventing the water supplied from the first purification cartridge (14) to the second purification cartridge (16). Thus, preventing the water flow to the storage tank (38). When the water level in the storage tank (38) is below the maximum level, the float (102) moves down thereby moving the valve spool to the open position in which the valve spool (108) allows water flow from the water inlet port (114) to the water outlet port (116) thereby allowing water flow from the first water purification device (14) to the second water purification device (16).
The technical advantages of the present invention are as follows: The apparatus (100) prevents the storage tank (38) from overflowing when the water level reaches a maximum level and/or prevent the unnecessary waste of water. The apparatus (100) eliminates the need for a water-level control system that uses water level indicators or sensors, for example, conductivity and weight sensors, and one or more solenoid valves for detecting and controlling the water level in the storage tank of a water purifier.
The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modifications within the scope of the embodiments as described herein.
