Description

Float device and method for controlling the timely fall of the buoy, water inlet valve and drain valve

technical field

The invention relates to the field of sanitary ware, in particular to a buoy device, a method for controlling the timely drop of the buoy, a water inlet valve, and a water discharge valve.

Background technique

In the toilet water parts, the lifting drive mechanism of the buoy is often used to move. For example, the buoy of the water inlet valve controls the opening and closing of the water inlet channel of the water inlet valve by lifting the buoy, and the buoy of the drain valve drives the valve plate to open by rising. In order to make the buoy move in place quickly, the buoy is usually placed in a buoy seat (or called an outer buoy). lift up. In order to ensure that the buoy can fall after the water level drops, a one-way switch is usually installed at the lower end of the buoy seat. When the water level rises, the one-way switch closes the drain outlet at the lower end of the buoy seat. Influx from the top of the buoy seat; after the water level drops to a certain level, the one-way switch opens the drain of the buoy seat, and the water flows out of the buoy seat from the bottom of the buoy seat, causing the buoy to descend. The above structure is generally shown in Figure 1. The one-way switch 3' is a float that rises under buoyancy in the water, and its upper surface is in close contact with the lower surface of the buoy seat 2' to form a seal, so that water cannot flow from the outlet at the bottom of the buoy seat 2'. Enter; after the external water level of the buoy seat 2' drops to a certain level, the pressure generated by the internal and external water level difference is greater than the buoyancy of the one-way switch 3', the one-way switch 3' is turned on, and the water flows out from the hole at the bottom of the buoy seat 2', making the buoy 1 'whereabouts.

However, the above-mentioned structure has the following problems. To make the pressure generated by the water level difference inside and outside the buoy seat be greater than the buoyancy of the one-way switch, the water level in the water tank must drop to a very low position. will fall. If the buoy does not fall, the parts linked with it will not be able to move in time. Taking the rise of the buoy to drive the opening of the drain valve cover as an example, if the buoy cannot be lowered in time, the drain valve cover cannot be closed in time due to the traction of the buoy, resulting in more displacement than is actually required. In the existing structure, in order to ensure that the one-way switch is reliably closed when the water level rises, the buoyancy of the one-way switch is set to be large, so that the water level often has to be lowered below the one-way switch before the buoy can fall, which makes the above problems more serious.

Detailed ways

Embodiment 1, please refer to Fig. 2-Fig. 8, a buoy device of the present invention is applied to a water tank, especially a toilet water tank, and includes a buoy seat 2, a one-way switch 3 and is located in the buoy seat 2 and can be subjected to The floating drum 1 floated by the buoyancy, the upper end of the buoy seat 2 is provided with an opening 21 to prevent the water in the buoy 1 and the water supply tank from entering the buoy seat 2; the lower end of the buoy seat 2 is provided with a drain port 22, one-way The switch 3 is movably installed at the water outlet 22, and the water outlet 22 is closed when the one-way switch 3 floats up to the position; The water inlet structure, and the drainage structure capable of draining the water storage chamber 33; after the buoy seat 2 is filled with water, the buoy 1 is subjected to buoyancy (if the buoy is not subjected to the external force that restricts its floating at this time, the buoy can float), And part of the water in the buoy seat 2 enters the water storage chamber 33 from the water inlet structure, and the water storage chamber 33 is filled up, so that the one-way switch 3 opens the water outlet 22 of the buoy seat. The one-way switch 3 is a float structure, and its density is the same as or close to that of water.

In this embodiment, the drainage structure is a throttling hole 34 located below the upper end of the one-way switch 3 and communicated with the water storage chamber 33 , before the buoy seat 2 enters water or in the buoy seat 2 Before the water enters the water storage chamber 33, the water storage chamber 33 of the one-way switch 3 does not need to be filled with water. In this way, after the water in the water tank 4 has passed through the orifice 34, the water slowly flows into the water storage chamber 33 of the one-way switch 3 from the orifice 34, and the section of the orifice is 1/4 of the section of the upper water inlet. 1/20, preferably 1/10, but the rising speed of the water level of the water storage chamber 33 of the one-way switch 3 is much lower than the rising speed of the external water level, so that the external water level rises to the front of the buoy seat 2, and the one-way switch 3 All can't be filled with water in the water storage chamber 33. In other embodiments, the drainage structure includes a water outlet provided at the lower end of the one-way switch and a one-way valve movably mounted on the water outlet. The one-way valve closes the water outlet when it floats up and opens the water outlet when it falls. The water port, the one-way valve realizes floating or falling according to the height of the water level in the water tank.

In this embodiment, the throttle hole 34 is specifically located on the lower end surface of the one-way switch 3, but it is not limited thereto. In other embodiments, the throttle hole is located at the bottom of the side wall of the one-way switch, and as close as possible to the lower edge of the side wall of the one-way switch. In this way, the orifice 34 can drain the water in the water storage chamber 33 of the one-way switch 3 or as much as possible.

In this embodiment, the water inlet structure is a water inlet 31 provided at the upper end of the one-way switch 3 , and the water inlet 31 corresponds to the water outlet 22 up and down. In other embodiments, the water inlet structure includes a water inlet pipe, one end of which is connected to the water storage chamber 33 of the one-way switch, and the other end is connected to the inner chamber 2 of the buoy seat.

In this embodiment, the lower end of the buoy seat 2 is provided with a ring of water-stop flange 23 surrounding the water outlet 22, and the upper end of the one-way switch 3 abuts against the water-stop flange 23 when it floats up to the position. The water outlet 22 of the buoy seat 2 is sealed so that the water in the water tank cannot enter the buoy seat 2 from the water outlet 22 . The upper end of the one-way switch 3 is provided with several buckles 32 distributed at intervals, and each buckle 32 passes through the water outlet 22 upwards respectively, and is stuck on the upper edge of the water outlet 22, so that the one-way switch 3 is Upside down. The plurality of buckles 32 are specifically distributed along the circumferential direction of the water inlet 31 at intervals, and the number of the buckles 32 is specifically four, but not limited thereto.

A kind of buoy device of the present invention, its working principle is as follows:

Low water level state: the water level of the water tank 4 is low, and the buoy 1 and the one-way switch 3 respectively fall to the limit position naturally, as shown in Figure 4;

The water inlet process of the orifice 34:

(1) The water level of the water tank 4 rises to a height exceeding the lower end of the one-way switch 3, and the one-way switch 3 is raised by buoyancy, and its upper surface cooperates with the water-stop flange 23 on the lower end surface of the buoy seat 2 to form a seal, as shown in Figure 5 , so that the water in the water tank 4 cannot enter from the drain port 22 at the lower end of the buoy seat 2;

(2) Water slowly flows into the one-way switch 3 from the orifice 34 at the lower end of the one-way switch 3, as shown in Figure 5, but the water level rise rate of the water storage cavity 33 of the one-way switch 3 is lower than the water level rise rate of the water tank 4 , before the water level in the water tank 4 rises to the upper end of the buoy seat 2, the water storage cavity 33 of the one-way switch 3 cannot be filled with water;

Lifting process of buoy 1:

(1) The water level in the water tank 4 rises to overflow the upper end of the buoy seat 2, and the water pours into the buoy seat 2 to quickly lift the buoy 1 (assuming that the buoy 1 is not subjected to the external force that restricts its floating), as shown in Figure 6 ;

(2) The water in the buoy seat 2 flows into the water storage chamber 33 of the one-way switch 3 through the water outlet 22 and the water inlet 31 from top to bottom, and the water storage chamber 33 of the one-way switch 3 is filled with water, Because the density of the material of the one-way switch 3 itself is similar to that of water, the one-way switch 3 changes from the floating state to the suspended state of opening the drain port 22 of the buoy seat 2, as shown in Figure 6;

The falling process of buoy 1:

(1) The water level in the water tank 4 falls, because the one-way switch 3 is in a suspended state, it will not cause the drain port 22 at the lower end of the float seat 2 to be closed, so the water in the float seat 2 will flow out through the drain port 22 at the lower end of the float seat 2 , the buoy 1 falls as the water level drops, as shown in Figure 7;

One-way switch 3 drainage process:

(1) The water level in the water tank 4 drops below the one-way switch 3, the water in the buoy seat 2 is exhausted, and the buoy 1 falls completely, as shown in Figure 8;

(2) The water in the water storage cavity 33 of the one-way switch 3 flows out from the orifice 34 , as shown in FIG. 8 , the water is finally exhausted and returns to the low water level state.

In a buoy device of the present invention, the one-way switch 3 is provided with the water storage chamber 33 and the throttle hole 34, and when the water level rises, the throttle effect of the throttle hole 34 is used to maintain the one-way switch 3 for a period of time. In the floating state, ensure that the drain port 22 at the lower end of the buoy seat 2 is in a closed state. When the water level drops, water can flow away from the orifice 34 and return to the emptying state. Therefore, the one-way switch 3 of the present invention has realized that the water outlet 22 of the buoy seat 2 does not enter water when the water level rises, and the water level drops the water outlet 22 of the buoy seat 2 to open the one-way function of drainage in time. In the process of rising water level, the present invention, the same as the prior art, ensures that the buoy 1 does not follow the water level rise at the beginning, and the buoy 1 rises at once after the water level has not crossed the buoy seat 2 (assuming that the buoy 1 is not restricted by the external force of its floating ); in the process of water level drop, the present invention can ensure that the buoy 1 falls in time following the drop of the water level, thereby solving the hysteresis problem existing in the prior art. In addition, the present invention also has the characteristics of simple overall structure, low cost, and easy installation.

A method for controlling the timely fall of the buoy according to the present invention, the buoy is located in the buoy seat, the buoy seat is located in the water tank, and the lower end of the buoy seat is provided with a drain, and the drain is movable with a one-way switch, the one-way switch Close the drain when the float is in place; there is a water storage chamber on the one-way switch. After the water in the water tank overflows the buoy seat, the buoy seat enters the water, and the buoy floats up under the action of buoyancy, and part of the water in the buoy seat enters the storage of the one-way switch. In the water chamber, until the one-way switch opens the drain of the buoy seat; as the water level of the water tank drops, the water in the water storage chamber is discharged.

In this embodiment, a drainage structure capable of draining the water storage chamber is provided on the one-way switch, and the drainage structure is a throttling valve arranged below the upper end of the one-way switch and communicated with the water storage chamber. hole, before the buoy seat enters the water or before the water in the buoy seat enters the water storage chamber, the water storage chamber of the one-way switch is not filled with water. In other embodiments, the drainage structure includes a water outlet provided at the lower end of the one-way switch and a one-way valve movably mounted on the water outlet. The one-way valve closes the water outlet when it floats up and opens the water outlet when it falls. The water port, the one-way valve realizes floating or falling according to the height of the water level in the water tank.

In this embodiment, a water inlet structure connecting the water storage chamber and the inner chamber of the buoy seat is provided on the one-way switch. The up and down corresponding to the drain outlet.

A method for controlling the timely fall of the buoy of the present invention can be realized by using the above-mentioned buoy device of the present invention, and its specific working principle is as described above, and will not be repeated here.

Please refer to Fig. 9, a water inlet valve of the present invention includes a water inlet valve body 5, and also includes a buoy device as described above in the present invention, the buoy 1 is linked with the water inlet valve body 5 through a linkage component, To control the water intake of the water inlet valve main body 5 or not. Specifically, the linkage component may be the lifting rod assembly 6, etc., which is a prior art and will not be repeated here.

In this embodiment, the buoy seat 2 can be installed at a suitable height outside the main body 5 of the water inlet valve.

In the water inlet valve of the present invention, after the buoy device is used, when the water level in the toilet tank 4 reaches the lowest level, the buoy 1 and the one-way switch 3 will naturally drop to the limit positions respectively, and the buoy 1 will drive the lifting rod assembly 6 to open and move forward. The internal waterway of the water valve main body 5 allows water to enter the water tank 4 to replenish the water tank 4 . When the water level in the water tank 4 rises to pour into the buoy seat 2, the buoy 1 rises, thereby driving the lifting rod assembly 6 to close the internal waterway of the water inlet valve main body 5 in time, so that the water inlet valve main body 5 stops water intake, achieving water saving Purpose. When the water level of the water tank 4 drops, the water level in the buoy seat 2 drops in time, so that the buoy 1 can fall in time, thereby driving the lifting rod assembly 6 to open the internal waterway of the water inlet valve body 5 in time, so that the water inlet valve body 5 starts to enter water , thereby avoiding that the main body of the water inlet valve 5 is affected by the delay of water inlet due to the failure of the buoy to fall in time.

Please refer to Fig. 9, a drain valve of the present invention includes a clapper cover 7, and also includes a buoy device as described above in the present invention, the clapper cover 7 is connected to the drain switch (not shown in the figure) Embodied) connection, when the drain switch is operated (as pressed or toggled, etc.), the buoy 1 is pulled to float up, and the flap cover 7 is opened in linkage.

In this embodiment, the connecting part is specifically a stay rope 8 (or a chain, etc.), which is connected to the buoy 1, and its lower end is connected to the clapper cover 7, and its upper end is connected to a drain switch, so that the buoy 1 is drained. When pulling to float up, the clapper cover 7 can be pulled by the stay cord 8, so that the clapper cover 7 is opened. The drain switch may be a push-type drain switch or a toggle-type drain switch, which is a prior art, and will not be repeated here.

In this embodiment, the buoy seat 2 is set on the overflow pipe 9 of the drain valve of the present invention, and the height can be adjusted.

In the drain valve of the present invention, before the toilet tank 4 drains water, there is water in the buoy seat 2, and the one-way switch 3 is in the suspension state of opening the drain port 22 of the buoy seat 2. At this time, the buoy 1 is held by the flap 7 and unable to float. When the drain switch is operated to start draining, the buoy 1 rises rapidly due to the combined action of upward pulling force and buoyancy, and pulls the clapper cover 7 by the stay rope 8, so that the clapper cover 7 is opened quickly, so that the water tank 4 is drained. When the water level of the water tank 4 drops, because the one-way switch 3 is in a suspended state, the drain port 22 at the lower end of the buoy seat 2 will not be closed. When the water level in the water tank 4 drops below the one-way switch 3, the water in the buoy seat 2 is exhausted, and the buoy 1 falls completely, thereby driving the clapper cover 7 to be closed in time to prevent the displacement from exceeding the actual needs.

A drain valve of the present invention, by setting the buoy device, not only can the flap cover 7 be closed in time to achieve the purpose of saving water, but also can use the buoyancy received by the buoy to reduce the pull-up force of the pull rope 8, thereby reducing drainage. The operating force of the switch (ie pressing force or other operating force).
