Description

Dual-purpose toilet bowl for flushing and foam plugging

Technical Field

The utility model relates to a water flushing and foam plugging dual-purpose toilet bowl, belonging to the technical field of toilet bowls.

Background

The water closet consists of the following main parts: water inlet pipe, water outlet pipe, water seepage pipe, water plug (water inlet and water outlet), floating ball, water discharge knob and lever, water supply mechanism, water tank, and urinal (the urinal has a bent pipe communicated with the water tank).

The basic principle of a toilet bowl is to utilize the gravity of water to convert the potential energy of water into the kinetic energy of water, so as to entrain excrement and dirt into a sewer pipe.

In recent years, a closestool with a foaming function is also available in the market, excrement is wrapped and covered by foam, odor emission and dirty water splashing are prevented, the foam has the functions of lubricating, decontaminating, fragrance emitting, sterilizing and disinfecting, and water can be saved.

The foaming system of the existing closestool with the foaming function comprises a foaming container and a foaming agent container which are both arranged inside a closestool water tank; and (3) a water replenishing mode of the foaming container: one is to use a micro water pump to draw water from a water tank or an electromagnetic valve to connect a tap water pipe, and the other is to arrange a one-way valve at the lower part to feed water by the pressure of the water in the water tank; the supply mode of the foaming agent generated by the foaming system is that a micro-water pump is used for pumping the liquid foaming agent from a foaming agent container to a foaming box, and the micro-water pump works for only a few seconds to be used for foaming for many times.

Example 1

As shown in fig. 1, the toilet bowl for both flushing and foam sealing comprises a toilet bowl 10, a foaming system for foaming and delivering foam generated by foaming to a bowl 11 inside the toilet bowl 10, a base plate 20 installed below the toilet bowl 10, and a waste pipe 12 located below the bowl 11, wherein the lower part of the toilet bowl 10 is fixedly connected with the upper part of the base plate 20, and a waste pipe 21 communicated with the waste pipe 12 is embedded in the base plate 20.

Firstly, the toilet bowl 10 is a conventional toilet bowl, and the toilet bowl 10 further includes a toilet lid 13, a water tank 14, and other components, and detailed details thereof are not repeated. The foaming principle of the foaming system is as follows:

the foaming system comprises a foaming box, a foaming agent box filled with foaming agent and an air supply device, wherein the foaming box and the foaming agent box can be arranged inside the water tank 14 or in other areas according to requirements. The air supply device is usually a micro air pump, one or more air supply devices can be arranged according to the requirement, and a sound insulation/waterproof box can be arranged outside according to the requirement. The micro water pump is connected with a one-way valve, liquid foaming agent is pumped to the foaming box from the foaming agent box by the micro water pump, the water closet 10 is provided with a corresponding water channel and a corresponding foam channel, and foam in the foaming box is finally discharged to the interior of the urinal 11 from the liquid outlet hole 111 through the foam channel, so that the interior of the urinal 11 is subjected to foam plugging.

The structure and principle of the foaming system are mature technologies, and reference may be made specifically to the "research on intelligent foaming toilet bowl" in the paper of the facial charm of the high mingming-hua ceramic sanitary ware limited in the mountain, CN201520569161.2 "toilet bowl with foaming function", and publication No. CN212336205U "foaming device and intelligent toilet bowl", etc., and the specific structure of the foaming system of the present invention is not limited to the structure listed in the present embodiment, as long as the function of "foaming and delivering the foam generated by foaming to the urinal 11 inside the toilet bowl 10" can be achieved. In addition, the research on the intelligent foaming closestool is a closestool with a foaming function, which is manufactured by modifying the traditional toilet bowl.

When the water flushing operation is required, the water flushing operation is turned on by a corresponding switch (including, but not limited to, a mechanical switch/an inductive switch), and the water inside the tank 14 is finally discharged from the outlet hole 112 to the inside of the urinal 11 through the water passage, thereby performing the water flushing operation on the inside of the urinal 11.

In this embodiment, the substrate 20 may be different according to an actual application scenario, and the substrate 20 may be a floor, or other installation structure. The sewer pipe 21 is connected to a sewer.

As shown in fig. 1-3, a blocking valve 30 is disposed between the upper end of the sewer pipe 21 and the lower end of the defecation pipe 12, the blocking valve 30 includes a joint and a valve body, the joint includes a circular gasket 511, an upper pipe body 512 and a lower pipe body 513, the upper pipe body 512 and the lower pipe body 513 are communicated with the lower end of the defecation pipe 12, the gasket 511 is connected with the upper pipe body 512 and the lower pipe body 513, and the inner cavity of the upper pipe body 512 is communicated with the inner cavity of the lower pipe body 513; the valve body sequentially comprises a sleeve body 521, a buffering bag 522 with a V-shaped cross section and a soft flat pipe 53 from top to bottom, the sleeve body 521 is sleeved outside the lower pipe body 513, the sleeve body 521 and the buffering bag 522 are connected into a whole, the buffering bag 522 and the soft flat pipe 53 are connected into a whole, an inner cavity of the sleeve body 521 is communicated with an inner cavity of the buffering bag 522, and an inner cavity of the buffering bag 522 is communicated with an inner cavity of the soft flat pipe 53; two sides of the soft flat pipe 53 are respectively provided with a crease 532, and the soft flat pipe 53 is divided into two half pipe bodies 531 which are oppositely arranged by the crease 532; the outer part of one of the half tube bodies 531 is fixedly provided with a strip-shaped electromagnet 54, the outer part of the other half tube body 531 is fixedly provided with a strip-shaped permanent magnet 58, and the permanent magnet 58 and the electromagnet 54 are oppositely arranged.

In this embodiment, the sheath 521, the buffering bag 522 and the flat hose 53 are integrally formed, the sheath 521, the buffering bag 522 and the flat hose 53 are respectively made of silicone rubber/silica gel with different hardness/thickness, and the hardness and the thickness are sequentially from large to small for the sheath 521 to be larger than the buffering bag 522 and larger than the flat hose 53. The hardness can be adjusted by subsequent vulcanization temperatures, such as high temperature vulcanization and room temperature vulcanization. The flat flexible tube 53 is formed by flattening the original tube, so that two half tube bodies 531 which are folded in half are formed, and the boundary is a crease 532.

In the initial state, since the electromagnet 54 is not energized, its housing acts as an "iron block" which is attracted by the permanent magnet 58 under the magnetic force, so as to urge the two half tubes 531 to abut against each other, thereby closing the flat flexible tubes 53. In fact, if the permanent magnet 58 and the electromagnet 54 are replaced by corresponding counter weights, a certain plugging effect is achieved under the action of gravity, but the plugging effect is not particularly good, and the matching between the permanent magnet 58 and the electromagnet 54 is not good.

When the mixture of sewage/filth and the like flows from the urinal 11, the defecation pipeline 12 to the plugging valve 30, and the mixture of sewage/filth and the like sequentially passes through the upper pipe body 512, the lower pipe body 513, the sleeve body 521, the buffer bag 522 and the flat hose 53, although the initial flat hose 53 is in a closed state, the two half pipe bodies 531 are flushed away under the gravity of the mixture of sewage/filth and the like, so that the flat hose 53 is in a dredging state, and the mixture of sewage/filth and the like finally flows to the sewer pipeline 21.

If an accident occurs, the soft flat pipe 53 is blocked, the electromagnet 54 is electrified at the moment, the electromagnet 54 is electrified to generate the magnetic force which is repellent to the permanent magnet 58, and the soft flat pipe 53 is forcibly opened under the action of the repellent magnetic force, so that the forced dredging effect is achieved.

Because the permanent magnet 58 and the electromagnet 54 both have a certain length, the soft flat pipe 53 cannot be opened without limitation under the action of the repulsive magnetic force between the electromagnet 54 and the permanent magnet 58, so that the soft flat pipe 53 is prevented from being torn. In addition, preferably, a is a half or one third of the inner diameter of the sewer pipe 21, and the length of the electromagnet 54 and the length of the permanent magnet 58 are both smaller than a. This enables the diameter of the opened soft flat tube 53 to be sufficiently large, thereby satisfying the dredging effect.

As for all power supply problems of the electromagnet 54, whether to install a power converter is selected according to an application scene by using a power supply used by the existing foaming system.

Due to the action of the magnetic force and the elasticity of the soft flat pipe 53, the soft flat pipe 53 can be kept in a blocking state in an initial state, the space between the sewer pipeline 21 and the urinal 11 is completely blocked, the functions of smell isolation, water return prevention, insect prevention and the like are achieved, and the effect that a mixture of sewage/dirt and the like is discharged into the sewer pipeline 21 is not influenced. Even the soft flat pipe 53 is blocked, the dredging can be forced, and the dredging operation is simple and convenient.

Further, the length direction of the electromagnet 54 is parallel to the width direction of the half pipe 531. This can minimize the length of the electromagnet 54 when the electromagnet 54 functions.

Example 2

As shown in fig. 2 and 3, in order to facilitate installation and further improve sealing performance; the upper end of the sleeve body 521 is provided with a flange 524, the flange 524 is arranged below the gasket 511, and the flange 524 is connected with the gasket 511 in a sealing manner.

The gasket 511 is sealingly mounted above the base plate 20. And sealing connection is realized by adopting a sealant beating mode.

Example 3

As shown in fig. 2 and 3, to further improve the sealing property; the outer ring of the sleeve body 521 is provided with a plurality of convex ribs 523.

Example 4

As shown in fig. 3, in order to facilitate installation of the lead-out wire of the electromagnet 54, a first lead hole 5111 is disposed at the gasket 511, a second lead hole is disposed at the rib 523, and a third lead hole is disposed at the flange 524. After the lead is placed at the first lead hole 5111, the second lead hole, and the third lead hole, glue may be applied to seal the lead.

Example 5

As shown in fig. 2 and 3, the outer portion of the electromagnet 54 and the outer portion of the permanent magnet 58 are coated with a waterproof layer 55.

The waterproof layer 55 may be coated with a waterproof epoxy resin adhesive.

Example 6

When the thickness of the soft flat tube 53 is too thin, the sealability is further improved; as shown in fig. 4, a division bar 56 corresponding to the position of the electromagnet 54/the permanent magnet 58 is arranged inside the soft flat pipe 53, the division bar 56 includes an elastic rib 534, and the elastic rib 534 is connected with the inner wall of the soft flat pipe 53 into a whole.

The elastic ribs 534 and the soft flat tubes 53 can be made of the same material.

The elastic rib 534 exists, when the electromagnet 54 and the permanent magnet 58 clamp the soft flat pipe 53, the soft flat pipe 53 can be quickly sealed at the elastic rib 534.

Example 7

Based on embodiment 6, as shown in fig. 4, the division bar 56 further includes a sponge bar 533, and the sponge bar 533 is connected with the inner wall of the soft flat tube 53 as a whole.

If the resilient bead 534 is too long and the electromagnet 54 is too short, the seal may be poor near the fold 532 due to uneven forces; alternatively, if only a small amount of sewage is in the interior of the flexible flat tubes 53, the momentum of the sewage may be insufficient to push the closed flexible flat tubes 53 open. Therefore, the sponge strips 533 are designed, and even if the sponge strips 533 are compressed to a certain degree, sewage can slowly seep downwards at the position, and the purpose of drainage is finally achieved; meanwhile, the sponge strip 533 can be wetted for a long time, and can also play a role in isolating the smell.

Example 8

To avoid interference at the fold 532, as shown in fig. 4, the end of the sponge bar 533 near the fold 532 is configured as a circular arc.

Meanwhile, in order to facilitate more flexible deformation of the sponge strip 533, the upper two sides of the sponge strip 533 are provided with the cutting marks 5331 which are distributed in a staggered manner.

Example 9

As shown in fig. 5, the lower portion of the half pipe body 531 is provided with an identification line 535. The identification line 535 is a warning line, the lower part of the soft flat pipe 53 can be reserved with a longer length when leaving a factory, and the installer can cut the lower part of the soft flat pipe 53 according to the actual situation when installing on the spot, but the cutting cannot exceed the identification line 535. Thereby ensuring that the soft flat pipe 53 can be normally opened, closed and operated.

In the embodiment, the water flushing and foam plugging dual-purpose toilet bowl has the functions of water flushing and foam plugging, and also has the functions of odor isolation, water return prevention, insect prevention and the like, and simultaneously does not influence the discharge of sewage/dirt and other mixtures into a sewer pipe. Even if the soft flat pipe is blocked, the soft flat pipe can be forcibly dredged, and the dredging operation is simple and convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
