BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device for automatically watering a lawn or farmland, humidifying a room or the like, or supplying water to a pool when necessary, at a position requiring water. The present invention relates to an automatic water supply control device that can automatically switch on water so that water flows when it senses that a moisture detecting member placed is dry. Note that this is an automatic water supply control device that does not require electricity to supply water.

2. Description of the Related Art Conventionally, many automatic water supply devices and irrigation devices have been provided. The most common of these devices are those used for under-grazing marginal water dispensers on lawns, which are set on clocks and timers. These devices provide watering by means of a control valve element of an electric solenoid that operates at predetermined time intervals. However, these devices are switched on even when it is not necessary to give water, for example, when it is raining, and on the other hand, they are automatically switched off even when watering is still insufficient. was there. Moreover, these devices had to require expensive electrical timers and the power supply itself.
Devices that rely on electricity also have the problem of being affected by power failures, electricity shortages, or solenoid failures. Many attempts have been made in the past to solve this important problem. On the other hand, the reliability of the operation was low in the device that did not rely on electricity.

In Beckman, US Pat. No. 4,214,701, an inflatable member is mounted around a water supply pipe. Upon sensing moisture, this member expands to block the tube and block the flow of water. However, such operation is unreliable and inaccurate and must not be used in sprinklers such as are commonly used today around the home. United States Patent No. 3,874,59 granted to Gibson
In No. 0, the expansion member opens and closes the switch when moisture is detected. However, the control valve element for opening and closing this is provided in the ground, and requires a complicated opening and closing device. It is not desirable that all the devices be installed in the ground, the diameter of the pipe or the like must be physically changed in order to operate, and the reliability of operation of the valve body was low.

US Pat. No. 2,445,717
In No. 3, a ceramic member is buried in the ground so as to be located under a water-filled and sealed vertical pipe. A pressure sensing partition is provided at the top of the vertical pipe, and the pressure sensing partition is configured to operate a valve body for controlling the irrigation device. When the soil surrounding the ceramic member is dry, water seeps into the ground, creating a low pressure zone in the vertical pipe above the water, resulting in a pressure differential on the bulkhead, which causes the farmland to grow. Switch on to allow water to be irrigated. When water is submerged in the ground, the flow of water moves in the opposite direction, the pressure in the partition wall is balanced again, and the valve body is closed. In this device, the water in the vertical pipe must be filled regularly, and it must be carried out to the ground during the periodic inspection. The resulting pressure differential is relatively small, limiting the reliability of the device.

In the device shown in US Pat. No. 3,747,399 to Trailer, the pressure differential is created by a wick inserted at the end of the tube.
The pipe is in contact with the soil, and moisture is allowed to enter the pipe and replaced with the air in the pipe to compress and activate the pressure sensing switch. Devices using such capillary action are unreliable because they are immediately affected by obstacles and operate slowly with small pressure differences.

The apparatus of US Pat. No. 2,863,698 to Richard utilizes the flow of water through the capillary pores of a ceramic chamber to create a pressure differential in the chamber and open the valve body. Is. However, the pressure generated by the capillary holes is small and the operation is slow.

US Pat. No. 3,981,446
In this issue, a water column is used to control the valve body. The tube is sized so that no water will flow out when it is open to atmospheric pressure. The valve body is adapted to operate in response to a change in pressure inside the water column. The pressure difference that occurs here is also small.

The device shown in US Pat. No. 2,215,132 to Parker utilizes a stream of water through an outdoor domestic water faucet connected to a Venturi device to provide a water pipe. It causes a suction action so that water-based fertilizer can be added. However, Parker's device is not used to control the flow of water, but only for mixing water with aqueous fertilizer at the outlet of the water pipe.

(Means and Actions for Solving the Problems) An object of the present invention is to provide a highly reliable automatic water supply control device.

It is also an object of the present invention to provide a reliable automatic water supply controller that does not require power.

Further, it is an object of the present invention to provide an automatic water supply control device which can be easily installed in place of the currently used automatic watering device.

Further, it is an object of the present invention to provide an automatic water supply control device which can be used as a humidifier.

It is a further object of the present invention to provide an automatic water supply control system which is activated only when needed.

Further, it is an object of the present invention to provide an automatic water supply control device which is highly reliable and does not require maintenance and inspection for a long period.

The above and other objects of the present invention are as follows.
It will be apparent from the following description and the accompanying drawings.

The present invention provides an automatic water supply control device which can be immediately used in place of the electrically controlled automatic water sprinkler device which is widely used around the home for watering lawns. The device according to the invention can be used both as an automatic water supply controller for pools and as a humidifier.

In the automatic water supply control device according to the present invention, the pressure sensing valve body is used to control the valve body of the main water pipe. A ceramic or plastic member is connected to the end of the first air shutoff tube, and the other end of the first air shutoff tube is in communication with an airtight chamber on one side of the partition wall of the pressure sensing valve body. . Ceramic or plastic parts should be placed in the soil area to be refilled, or at the water level you want to maintain if used to control the water level in the pool, and if used as a humidifier. Install it in a room where you want to maintain the desired humidity. Ceramic and plastic components are permeable to the atmosphere when dry and block the atmosphere when immersed in water or sensing moisture.

The venturi pipe device is mounted in the immediate vicinity of the supply port of the main water pipe connected to the automatic water supply control device. One end of the second atmosphere cutoff tube is connected to the low pressure region of the Venturi tube device, and the other end of the second atmosphere cutoff tube is connected to the ceramic or plastic member of the first atmosphere. It is connected to the airtight chamber like the end of the shutoff tube.

The water flowing from the main water pipe through the Venturi device is the atmosphere from the second atmosphere shutoff pipe, the atmosphere from the airtight chamber above the partition of the pressure sensing valve, and the first air shutoff. A suction force is generated at one end of the second air cutoff tube that draws in the air from the tube. When the ceramic or plastic part is dry, the atmosphere passes through this part, enters the first air shut-off pipe leading to the airtight chamber and exits the second air shut-off pipe. In this way, the atmosphere is continuously supplied to the airtight small chamber, and a pressure difference does not occur in the airtight small chamber due to suction from the Venturi tube device. Therefore, the pressure sensing valve body remains open in the initial position and water continues to flow through the main water pipe.

For example, when water is sprayed or soaked in pool water, the ceramic or plastic member is in a state of blocking the atmosphere. Therefore, the atmosphere cannot enter the first atmosphere shutoff tube through these members. Suction from the Venturi device draws air from the first atmosphere shutoff tube, into the airtight chamber, and then from the second atmosphere shutoff tube. This is
A low pressure zone is created in an airtight chamber above the bulkhead of the pressure sensing valve and the pressure sensing valve is brought into close contact with the main water valve in a manner similar to conventional solenoid controlled valves. The one-way check valve body in the passage of the second air cutoff pipe is designed so that when the flow of water through the Venturi pipe device stops and suction from the Venturi pipe device stops, the atmosphere passes through the Venturi pipe device to the second atmosphere. Prevents entry into the shutoff tube.

When the ceramic or plastic parts are dry, the atmosphere can again pass through these parts into the first atmospheric shut-off tube and then into the airtight chamber and the pressure difference disappears. The spring-deflectable partition returns to its initial position, opening the main valve body again. This cycle is repeated thereafter.

(Embodiment) The present invention has a main valve body (10) and a pressure sensing valve body (100) as shown in FIGS. 1 and 2. The main valve body portion (10) includes a main valve body (11) and a low pipe portion (14) which communicates with the main valve body portion (10) and the communication location is sealed by an O-ring (16).

The low pipe portion (14) can be attached to, for example, a main valve body portion (10) having a normal non-siphon type valve body, and a piston (18) is inside an airtight small chamber (19). When it moves to the bottom of the cylindrical chamber (34), the valve body device (22) comes into close contact with the valve seat of the main valve body part (10). Therefore the spring (30) normally holds the valve closed.

In addition, water enters the cylindrical chamber (34) through the supply port (27) and applies water pressure to the top of the piston (18). Since the area of the piston is larger than the area of the valve body device (22), the action of the resulting water pressure holds the valve body in the closed position.

6) is provided inside. The protrusion (136) of the plunger pin (116) extends through the sealing insert (138) and below the lower first conical plug (122). The protrusion (136) is pivotally coupled to the arm lever (140) at a point (137), so that the arm lever (140)
Is pivotally mounted to the pressure sensing valve body (100) by a pivot (142) and has two conical plugs (126).

Is connected to the low pressure region (LP) of the discharge port (162) of the venturi pipe device (164) connected to the discharge port of the main valve body (11) in the supply port (WI) of the main water pipe.

In the preferred embodiment, a ceramic member (166) having a high atmospheric resistance is provided in the second atmospheric shutoff tube (154) to provide a one-way check valve body (1).
68) has a ball member (170) that is pressed against the valve seat (174) by a spring (172). The member (166) having a high atmospheric resistance is preferably formed of ceramic and is capable of gradually and only allowing a small amount of air to be permeable, either by a slightly air permeable physical structure or by the shape of the valve body. Made of shape, structure or material.

The guide valve device (115) is usually a spring (1
32) pressed downward by the second conical plug (126) blocking the flow of water through the guide passage (42), preventing water from flowing underneath the piston (18), Holds the main valve body (11) in the closed position.

It will be appreciated that the main valve body (11) is kept closed as long as water is prevented from flowing into the airtight chamber (19). However, once water flows into the airtight chamber (19), the main valve body (11) maintains the open state. The ceramic sensing member (152) is porous and has pores sized 12 microns or less. Therefore, when moisture is not present, the atmosphere can permeate the small pores, but when moisture is present, the small pores are blocked to prevent the atmosphere from permeating.

Ceramic sensing members are typically used for these applications, but other materials, such as plastic, can be used as long as they have small holes of the same size. This ceramic sensing member is disclosed in U.S. Pat. No. 3,758,987 to Crane.

In the preferred embodiment, the pores of the ceramic member (166) are less than 12 microns, but somewhat restrict the flow of atmospheric air through the pores, thereby causing the second atmospheric shutoff tube (154). A range of 6 to 8 microns is even more preferred for producing atmospheric resistance to.

The operation of this apparatus will be described in detail below. For ease of understanding, the operation of this device will first be described without much mention of the momentary shutoff device (200) and associated devices.

First, referring to FIGS. 2B and 2C, for example, an outlet (W) connected to an outdoor faucet or a sprinkler.
O) to a water source under pressure such as (WI)
The main valve (11) connected to will be described. The upper pressure sensing chamber (1

However, it is installed in the ground where water should be sprinkled or at the desired water level in the pool.

The main valve body (11) is initially closed to prevent it from passing through the Venturi device (164). Assuming that the handle (37) of the main valve body (10) is turned to open the main valve body (11), the following is obtained. When the arm lever (140) is pushed down to the horizontal position, the guide passage (42) is closed and water is allowed to flow in the control device. The water flowing in the Venturi device creates a low pressure at the point (LP), which in turn causes a suction force in the second atmospheric shutoff pipe (154), which is present in this second atmospheric shutoff pipe (154). Atmosphere, and the atmosphere in the upper pressure sensing chamber (112), and the ceramic sensing member (1
52) The air in the first air shutoff pipe (144) connected to 52) is sucked out. When the ceramic sensing member (152) is dry, the atmosphere is the first atmosphere shutoff tube (14).
4) to the ceramic sensing member (152) and the upper pressure sensing chamber (112). Therefore, the water sucks the atmosphere in the upper pressure sensing chamber (112), and the venturi device (1
64), the air pressure in the upper pressure sensing chamber (112) remains at a small vacuum pressure as the atmosphere is refilled through the ceramic sensing member (152), and the septum (104) initially covers the arm lever (140). It remains in the intermediate position that was moved by pushing it down. Water passes through the main valve body (11) and the venturi pipe device (164), and the main outlet (W
O), and continue to flow to the water pipes for sprinklers and pools.

When the ceramic sensing member (152) is sufficiently moistened by actuating the sprinkler, the atmosphere no longer flows through the ceramic sensing member (152) and the suction force generated by the Venturi device (164) is removed. Partition wall (10
4) resulting in a low pressure zone in the upper pressure sensing chamber (112) which moves the partition (104) from the intermediate position to the upper position shown in Figure 2C. The lower first conical plug (122) closes the guide passage (42), water does not enter the airtight chamber (19), and the main valve body (11) is closed.

As described above, there is disclosed a simple and reliable automatic water supply control device which can be immediately used for the water sprinkler currently in use and does not require maintenance, inspection, management, or electric parts. In addition, the instantaneous shutoff device (200) is introduced for two purposes, one is to momentarily shut off the flow of water in the control device, and the other is to use a lawn mower or the like. The first air shutoff pipe (14
This is to operate as a safety device even if all of 4) are opened.

Even when such control cannot be performed,
If the first atmosphere shutoff tube (144) is fully operational, the partition (104) in the upper pressure sensing chamber (112), even if the ceramic sensing member (152) is wet.
There is no low pressure on top. The main valve body (11) keeps its open state as if the ceramic sensing member (152) were dry. Instantaneous shutoff device (2
00) senses that it is in complete communication with atmospheric pressure,
Close the controller to shut off water as follows.

The instantaneous shutoff control device (200) is attached to the pressure sensing valve body (100). To manually shut off the valve body, it is sufficient to pull up the ring (201). By opening the passage (208) to the airtight chamber (112), the pressure in the upper pressure sensing chamber (112) above the partition (104) drops to normal atmospheric pressure. Therefore, the spring (132) pushes down the second conical plug (126) to close the guide passage (42), thereby closing the valve body.

While the automatic water supply control device is operating, the instantaneous cutoff control device (0200) is kept closed by the movement of the spring (230) and the vacuum pressure.

It can be seen that the main valve body (11) remains closed as long as it blocks the flow of water to the airtight chamber (19). However, once the water flows into the airtight chamber (19), the main valve body (11) maintains the open state. Referring to FIGS. 2 and 2A, the automatic water supply controller is shown in its initial position. The spring (132) has an upper second conical plug (12).
6) Push down on this second conical plug (126)
Closes the opening of the guide passage (42). Therefore, water cannot enter the airtight chamber (19) and the main valve body (11) will not be opened. As long as the second conical plug (126) holds this position, the main valve body (11) is closed and no water flows.

By slightly lowering the arm lever (140), the second conical plug (126) does not block the guide passage (42) (see FIG. 2B), and water is airtight through the guide passage (42). You can enter Komuro (19),
The main valve body (11) is opened. The water passes through the venturi pipe device (164), so that the check valve (16
8) and the second atmospheric shutoff pipe (154) is attracted.

This suction force generated by the Venturi device is sufficient to suck the atmosphere through the member (166) having a high atmospheric resistance, so that the atmosphere in the upper pressure sensing chamber (112) can be sucked. it can. If the ceramic sensing member (152) is wet, the suction force generated by the Venturi device (164) will cause the bulkhead (10).
4) is sufficient to create a low pressure area above and to pull the septum (104) up,
6) and the lower first conical plug (122) fixed to this plunger pin (116) is pulled up (see FIG. 2C). Therefore, the guide passage (42) is closed and the main valve body (1
1) is closed. The check valve body (168) prevents air from entering the device and the low pressure zone disappears.

If the ceramic sensing member (152) is dry, the atmosphere can enter the first atmospheric shutoff tube (144) and the upper pressure sensing chamber (112). The suction force generated by the Venturi device (164) is
4) is not enough to be able to lift up. The partition (104) moves down and the guide passage (42) is opened. This cycle repeats as the ceramic sensing member (152) dries and rewets.

For example, the pipe is cut or the ring (20
If the upper pressure sensing chamber (112) is in communication with the atmosphere, such as when (1) is lifted, the atmospheric pressure of the upper pressure sensing chamber (112) on the partition wall (104) becomes too large and the venturi becomes too large. The suction force created by the tube device (164) is insufficient to hold the septum (104) in the intermediate position. This is due to the high atmospheric resistance member (166) acting as a result of the limited amount of atmospheric air that can be sucked out by the Venturi device (164). The septum (104) is pulled downward by the spring (132) as in the position shown in Figure 2A.

The size of the high atmospheric resistance member (166) is
The spring (1) allows the guide passage (42) to be opened when the amount of air sucked out of the upper pressure sensing chamber (112) is blocked by the second conical plug (126).
32) is designed not to be sufficient to overcome the tension of 32).

When the high atmospheric resistance member (166) is dry, it has a breaking power ten times greater than the value of the atmospheric resistance of the ceramic sensing member (152). Thus, when the upper pressure sensing chamber (112) is open to the atmosphere, the low pressure range in the upper pressure sensing chamber (112) is
Not enough to overcome the tension of the spring (132). However, once the upper pressure sensing chamber (112) receives the atmosphere only from the first atmospheric shutoff pipe (144) and the ceramic sensing member (152) and the guide passage (42) is opened, the upper pressure sensing chamber (112) is opened. There is a spring (13) in (112).
There is a low enough pressure to overcome the tension of this spring (132) so that 2) cannot pull the plunger pin (116) up again. Water flowing to the main valve body (11) is blocked by rotating the handle (37),
In order to instantaneously and temporarily cut off the water supply, the arm lever (140) is lifted to block the guide passage (42) as shown in FIG. The flow of can be cut off.

While the preferred embodiment of the device according to the invention has been disclosed, as described above, it will be appreciated that other embodiments can be modified in various ways without departing from the spirit of the invention. Air resistance members other than ceramic can be used that have a different form of air movement from dry to wet.
