Abstract

The invention provides a kind of can multimode open draining valve.Draining valve comprises Connection Block and floating drum, and described Connection Block axial centre has an outfall, outfall periphery have be sealed and matched with floating drum close water convex edge, outfall and close between water convex edge and be provided with water storage flume.When needing draining, lift floating drum or arbitrary orientation thruster floating drum, water enters Connection Block water storage flume, and floating drum floats by buoyancy of water, starts draining, and after a certain amount of water to be discharged, buoyancy is not enough to support floating drum, and floating drum falls, and closes draining valve.Smart design due to this programme makes draining valve both by lift floating drum, can realize draining action, and also can realize draining action by arbitrary orientation thruster floating drum.

Description

A drain valve that can be opened in multiple ways

technical field

The invention relates to a toilet water tank drain valve, in particular to a drain valve which can be opened in multiple ways.

Background technique

At present, there are basically two types of drain valves on the market: one is a clap-type drain valve, and the other is a tank-type drain valve. The flap type drain valve generally uses the side wrench type for drainage, and the tank type drain valve generally uses the top button type for drainage, and some switch the button type to the wrench type through wire control. Button type and wrench type drainage occupy the mainstream of the market. But these two drainage operation modes can not satisfy the demands of consumers in general. For example, in a family, different family members prefer different drainage methods. Adults are taller than the toilet, so they like the top button drainage; children are short and cannot press the top button, and the wrench on the side can solve his problem very well. There are different ways of liking at different times. For example, in the process of going to the toilet, it is necessary to drain water. At this time, the side pull is much more convenient than the top push.

Some people like to set the drain valve button on the front of the water tank, and some people like to set a wrench on the top of the water tank that can be pulled in any direction to drain water, but unfortunately there is no toilet on the market that can meet the needs of multiple drainage methods at the same time.

The reason for the analysis is that most of the structure of the current drain valve adopts the method of pulling the valve cover to drain water. Those push-button and wrench types are converted from the pull-up type, so if you want to have multiple operation modes in the same toilet, then these modes may interfere with each other, and solving these problems will greatly increase the cost, which is impossible. fetched. Therefore, the present invention proposes an inexpensive multi-mode operation drain valve.

Contents of the invention

The invention provides a drain valve that can be opened in multiple ways. The drain valve includes a connecting seat and a buoy. The axial center of the connecting seat has a drain outlet. The periphery of the drain outlet has a water-closing lip that is sealingly matched with the buoy. A water storage tank is arranged between the drain port and the water-closing lip. When drainage is required, pull the buoy or push the buoy sideways at any direction, the water enters the storage tank of the connecting seat, the buoyancy of the water floats the buoy, and starts to drain. Drain valve. Due to the exquisite design of this scheme, the drainage valve can realize the drainage action by pulling the buoy, and can also realize the drainage action by pushing the buoy sideways in any direction.

As a preferred solution of the present invention: the water storage tank between the water-closing convex edge and the discharge outlet is an annular groove, the outer ring of the annular groove is the water-closing convex edge, and the inner ring is the convex edge along the perimeter of the water discharge outlet.

As a preferred solution of the present invention: the height of the inner ring of the annular groove is higher than the bottom of the groove, but not higher than the outer ring.

As a preferred solution of the present invention: the groove width of the annular groove is not less than 2 mm.

As a preferred solution of the present invention: the inner ring of the annular groove is provided with a water outlet, and the bottom surface of the water outlet is not higher than the lowest surface of the water storage tank.

As a preferred solution of the present invention: the bottom of the buoy has an inner ring surface and an outer ring surface respectively matched with the inner and outer rings of the annular groove of the connecting seat.

As a preferred solution of the present invention: the inner ring surface and the inner ring of the annular groove are in clearance fit, and the outer ring surface and the outer ring of the annular groove are in sealing fit.

As a preferred solution of the present invention: ribs can also be arranged on the periphery of the upper part of the buoy of the drain valve, and pulling holes are arranged on the ribs.

In the present invention, the cross section of the water storage tank may be U-shaped, trapezoidal, rectangular, triangular, or arc-shaped.

The beneficial effects of the present invention are: the function principle of the drain valve is different from that of the traditional drain valve, and the drainage can be realized by lifting and pushing the buoy in any direction. The drain valve has a simple structure and stable performance to meet the diverse needs of customers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS: The technical solution of the present invention will be specifically introduced below in conjunction with the accompanying drawings.

In FIG. 2 , a multi-mode operation toilet tank drain valve according to the present invention includes a connecting seat 100 and a buoy 200 , and the buoy 200 is sleeved on the connecting seat 100 . The connecting seat 100 is provided with a connecting rod 101 that protrudes upwards and fits in with the buoy 200. The drain port 102 runs through the axial center of the connecting seat 100. Above the connecting seat 100 and on the periphery of the drain port 102, there is a water-closing protrusion that is sealingly matched with the buoy 200. Along 103, an annular groove 104 for water storage is provided at the position where the water-closing convex edge 103 extends toward the axial center of the valve. 105 is the inner ring of the annular groove 104, and the height of the inner ring of the annular groove 104 is higher than the groove bottom, but not higher than the outer ring.

The axial center of the buoy 200 is provided with a central hole 201 that fits with the connecting rod 101, an inner ring surface 202 at the bottom of the buoy that fits with the convex edge 105, and an outer ring surface 203 at the bottom of the buoy that cooperates with the water-closing convex edge 103 , A gasket 204 is provided between the outer ring surface 203 and the water-closing lip 103 , and the gasket 204 is in sealing fit with the water-closing lip 103 when the drain valve is closed. Ribs 205 are also provided on the periphery of the upper part of the buoy 200 , and the ribs 205 are provided with lifting holes 206 for lifting the buoy 200 .

When drainage is required, push the upper part of the buoy 200 sideways, or pull the buoy 200 upwards, so that the sealing gasket 204 of the buoy 200 is separated from the water-closing convex edge 103 of the connection seat 100, and the water will enter the annular groove 104 of the connection seat 100. The buoyancy of the buoyancy will float the buoy 200, and then the drain valve will be opened. When the liquid level drops to a certain position and the buoyancy is not enough to support the buoy 200 , the buoy 200 falls, the drain valve is closed, and the residual water in the annular groove 105 flows out from the water outlet 106 .

The above embodiment is a preferred embodiment of the present invention, which is used to illustrate the technical characteristics and implementability of the present invention, and is not used to limit the patent right of the present invention; meanwhile, the above description is for those who are familiar with the technical field It should be clear and practicable. Therefore, other equivalent changes or modifications made without departing from the disclosure of the present invention should be included in the scope of the patent application.
