Description

Float device, water inlet valve and water discharge valve

Technical Field

The utility model relates to a bathroom field especially relates to a flotation pontoon device and water intaking valve and drain valve.

Background

In the toilet water part, the float is often moved by a lifting driving mechanism, for example, the inlet valve float controls the opening and closing of the inlet passage of the inlet valve by lifting, the drain valve float opens by lifting a driving valve piece, and the like. In order to make the buoy move in place quickly, the buoy is usually placed in a buoy seat (or called an outer buoy), and when the water level in the water tank rises above the buoy seat, the water level floods into the buoy seat, so that the buoy in the buoy seat is lifted up at a time. In order to ensure that the buoy can fall down after the water level falls, the lower end of the buoy seat is usually provided with a one-way switch, the one-way switch closes a water outlet at the lower end of the buoy seat when the water level rises, and water cannot enter the buoy seat from the bottom of the buoy seat and only can flow in from the upper part of the buoy seat; after the water level drops to a certain degree, the one-way switch opens the water outlet of the buoy seat, and water flows out of the buoy seat from the bottom of the buoy seat to enable the buoy to drop. The structure is generally shown in fig. 1, the one-way switch 3 ' is a floater, the one-way switch rises under the action of buoyancy in water, the upper surface of the one-way switch is tightly contacted with the lower surface of the buoy seat 2 ' to form a seal, and water cannot enter from a water outlet at the bottom of the buoy seat 2 '; after the water level outside the float bowl seat 2 ' is reduced to a certain degree, the pressure generated by the difference between the water level inside and outside is larger than the buoyancy of the one-way switch 3 ', the one-way switch 3 ' is opened, and water flows out from the hole at the bottom of the float bowl seat 2 ', so that the float bowl 1 ' falls.

However, the above structure has a problem in that the water level in the tank is lowered to a low level so that the pressure generated by the difference between the water levels inside and outside the float seat is greater than the buoyancy of the one-way switch, and the float does not fall at all until the water level in the tank is sufficiently lowered. The float bowl does not fall down, so that the linked parts can not act in time. By taking the case that the float bowl rises to drive the flap cover of the drain valve to be opened, if the float bowl cannot descend in time, the flap cover of the drain valve cannot be closed in time under the traction of the float bowl, so that the water discharge amount exceeds the actual requirement. In order to ensure that the one-way switch is reliably closed when the water level rises in the existing structure, the buoyancy of the one-way switch is set to be larger, so that the water level is often reduced to be below the one-way switch, and the buoy can fall down, thereby further causing the problems to be more serious.

(2) the water in the float bowl base 2 flows into the water storage cavity 33 of the one-way switch 3 sequentially through the water outlet 22 and the water inlet 31 from top to bottom, the water storage cavity 33 of the one-way switch 3 is filled with the water, and the one-way switch 3 is changed from a floating state to a suspension state for opening the water outlet 22 of the float bowl base 2 as shown in fig. 6 because the density of the material of the one-way switch 3 is similar to that of the water;

the falling process of the buoy 1:

(1) the water level in the water tank 4 falls, and the water outlet 22 at the lower end of the buoy base 2 is not closed because the one-way switch 3 is in a suspension state, so that the water in the buoy base 2 flows out through the water outlet 22 at the lower end of the buoy base 2, and the buoy 1 falls along with the falling of the water level, as shown in fig. 7;

one-way switch 3 drainage process:

(1) the water level in the water tank 4 is reduced below the one-way switch 3, the water in the buoy seat 2 is drained, and the buoy 1 completely falls down, as shown in fig. 8;

(2) the water in the water storage chamber 33 of the one-way switch 3 flows out through the orifice 34, and eventually drains off the water as shown in fig. 8, and returns to the low water level state.

The utility model discloses a flotation pontoon device, its one way switch 3 sets up water storage chamber 33 and orifice 34 utilize the throttle effect of orifice 34 when the water level rises, make one way switch 3 maintain the floating state of a period, ensure that outlet 22 of 2 lower extremes of flotation pontoon seat is in the closed condition, and when the water level descends, hydroenergy flows away from orifice 34, gets back to the evacuation state. Therefore, the utility model discloses a one way switch 3 has realized that the outlet 22 of rising pontoon seat 2 of water level does not intake, and the one way function of drainage is in time opened to the outlet 22 of decline pontoon seat 2 of water level. In the process of rising the water level, the utility model ensures that the buoy 1 does not rise along with the water level at the beginning like the prior art, and the buoy 1 rises at once after the water level is over the buoy seat 2 (assuming that the buoy 1 is not under the external force action for limiting the floating up of the buoy); in the water level decline in-process, the utility model discloses can ensure that flotation pontoon 1 in time follows the decline of water level and whereabouts to the lag problem that prior art exists has been solved. Furthermore, the utility model discloses still have overall structure simple, characteristics such as with low costs, simple installation.

Referring to fig. 9, the water inlet valve of the present invention includes a water inlet valve main body 5, and further includes a float device according to the present invention, wherein the float 1 is linked with the water inlet valve main body 5 through a linkage component to control whether the water inlet valve main body 5 is supplied with water or not. The linkage part may be specifically a lifting rod assembly 6, etc., which is prior art and will not be described herein.

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

The utility model discloses a water intaking valve adopts behind the buoy device, when the water level in toilet tank 4 reached minimum, extreme position was fallen down naturally respectively to flotation pontoon 1 and one way switch 3, and flotation pontoon 1 orders about and lifts pole subassembly 6 and open the inside water route of water intaking valve main part 5, makes in water gets into water tank 4, carries out the moisturizing to water tank 4. When the water level in the water tank 4 rises to flush into the buoy seat 2, the buoy 1 is rapidly lifted, so that the lifting rod assembly 6 is driven to close the internal waterway of the water inlet valve main body 5 in time, the water inlet valve main body 5 stops water inlet, and the purpose of saving water is achieved. When the water level of the water tank 4 drops, the water level in the float seat 2 drops in time, so that the float 1 can drop in time, the rod lifting assembly 6 is driven to open the inner waterway of the water inlet valve main body 5 in time, the water inlet valve main body 5 starts to enter water, and the water inlet valve main body 5 is prevented from being influenced by water inlet delay due to the fact that the float does not drop in time.

Please refer to fig. 9, the drain valve of the present invention includes a flap cover 7, and further includes a float device according to the present invention, wherein the flap cover 7 is connected to the drain switch (not shown) through a connecting component and the float 1, so that when the drain switch is operated (e.g. pressed or toggled), the float 1 is pulled to float, and the flap cover 7 is linked to open.

In this embodiment, the connection component is specifically a pull rope 8 (or may be a chain, etc.), which is connected to the buoy 1, and the lower end of the connection component is connected to the flap cover 7, and the upper end of the connection component is connected to the drain switch, so that when the buoy 1 is pulled to float by the drain switch, the flap cover 7 can be pulled by the pull rope 8, and the flap cover 7 is opened. The drainage switch may be a push type drainage switch or a toggle type drainage switch, which is the prior art and is not described herein again.
