Description

Drain valve for filling functional substance into toilet

Technical Field

The present invention relates to a drain valve for filling a functional liquid into a toilet, and more particularly to a drain valve installed in a toilet tank.

Background

At present, functional objects such as a toilet cleaning block or a toilet cleaner are placed at the upstream of a drain valve, even if a toilet is cleaned in a water tank of the toilet, the functional objects contain various chemical substances such as an active agent, a fragrance agent, a bactericide, a coloring agent and the like, so that the toilet can be conveniently cleaned, and the toilet environment can be beautified. The disadvantages are as follows: too large a tank results in too rapid diffusion of the functional substance, too high an initial concentration and a rapid decrease in concentration. 2. The function is that a particular chemical agent upstream of the flusher is liable to cause damage to the flusher. 3. After the water tank drainer is opened, all water with functional objects flows to the toilet bowl, most of the water flows into the toilet bowl and then flows out of the toilet bowl along with dirt to flow to a building pipeline, the effect of lasting cleaning and beautifying is not achieved, and waste is substantial. 4. The other scheme is that after the closestool is flushed, the agent is put in by a branch on a water inlet pipe of the water tank, and the defect that the water flow is small and a large ceramic dirt bearing surface cannot be cleaned is overcome. To overcome the above-mentioned shortcomings, it is a research direction to partially or completely solve the above-mentioned shortcomings, thereby improving the service life of the functional object, and to release the functional object by using the existing energy rather than introducing a new power element.

Disclosure of Invention

The application provides a drain valve to stool pot filling function thing mainly possesses: a drainage unit, which forms a seal or an opening at the water storage boundary of the water tank locally to stop or conduct a water path flowing to the sewage bearing surface of the toilet; the first waterway channel is connected to the downstream of the drainage unit and guides water to the dirt bearing surface of the toilet when the drainage unit is conducted; the second waterway channel is connected with the downstream of the drainage unit and guides the water in the water tank to the dirt bearing surface of the toilet bowl after the drainage unit is conducted; in particular, the second water channel also has a functional cavity for storing functional objects to be brought to the dirt-bearing surface of the toilet.

Preferably, the functional substance at least can be used for dredging the toilet or cleaning the toilet or can be used for perfuming or sterilizing the toilet or can be used for diluting and throwing the solid or liquid substance with changed color.

Preferably, the second waterway of the drain valve has an inlet to receive the water of the water tank to enter the second waterway, the inlet is located below the drain unit, and when the drain unit drains the water, kinetic energy and potential energy of the water tank drive the water of the water tank to flow into the second waterway through the inlet.

Preferably, at least a part of the functional cavity of the second waterway channel of the drain valve is set at a position higher than the drainage unit, so that the water in the functional cavity flows to the downstream of the drainage unit, and the height of the drain valve is reduced, so that the installation of the drain valve in the toilet is facilitated.

Optimized, the second waterway channel of the drain valve has a function cavity water inlet to accept the water from the inlet of the second waterway channel and guide the water into the function cavity, the function cavity water inlet is higher than the inlet, and the waterway channel from the inlet to the function cavity water inlet has an ascending section. The design utilizes potential energy and kinetic energy of water flow when the drainage unit drains water, so that water at a lower part flows upwards, and the functional cavity can be arranged at a higher position.

Optimally, the second waterway channel of the drain valve guides water flowing through the functional cavity into the first waterway channel, and the water flowing through the functional cavity is then guided to the dirt bearing surface of the toilet bowl through the first waterway channel.

Preferably, when a water tank inlet valve in the water tank feeds water into the water tank, a part of the water fed from the water tank inlet valve flows into the functional cavity to dilute or flush the functional substances in the functional cavity in a flowing manner and flows into the toilet stool through at least a part of the second waterway channel to form at least a part of the toilet stool water seal. Therefore, the functional substance can be filled into the toilet bowl when the drainage unit leads to the toilet bowl for flushing, and the functional substance can also be filled into the water seal when the water tank inlet valve is filled into the toilet bowl to form a water storage water seal.

Preferably, when the water tank water is discharged through the water discharge unit, the water tank water flowing through the second water channel reaches the dirt bearing surface of the toilet bowl later than the water tank water not flowing through the second water channel. The control of the outflow time difference of the first water channel and the second water channel can be achieved by setting the water inlet position, the pipeline length, the shape and the position of the functional cavity and the pipeline caliber of the first water channel and the second water channel, so that the functional material waste caused by the fact that the functional material is injected into the toilet in large quantity by the drain valve before the sewage is discharged by the toilet is avoided.

Optimally, when the water tank water is discharged through the drainage unit, the time for the water tank water flowing through the second water channel to reach the dirt bearing surface of the toilet bowl later than the water tank water not flowing through the second water channel is more than 1 second, so that the waste of the functional objects caused by the fact that the functional objects flowing through the second water channel are directly discharged out of the dirt bearing surface of the toilet bowl along with the dirt is reduced.

Optimally, the drain valve is also provided with a functional object operation unit for physically driving the functional object, the operation driving unit is used as a tool, the functional object can be stirred, rolled, shifted and the like, and the direct touch of hands is avoided. The functional object operation unit is very useful when the residual amount of the functional object is judged, the functional object is placed and the putting channel is accidentally blocked.

Preferably, at least a part of the functional substance operation unit of the drain valve is arranged in the functional cavity. Therefore, after the functional object operation unit is used, the functional object operation unit can be directly placed in the functional cavity, and the pollution of the functional object polluted by the functional object operation unit to the outside is avoided.

In summary, according to the present application, a drain valve for filling a functional material into a toilet bowl is provided, and when a dirty surface of the toilet bowl is cleaned, a part of flush water is divided into a small path and flows through a functional cavity containing the functional material, and then flows into the toilet bowl, so that the functional material contained in the flush water cleans the dirty surface. Because the volume of the functional cavity is small, the rapid diffusion of the functional substance can be effectively inhibited, the ultrahigh concentration at the initial stage is avoided, the initial period is prolonged, and the service life of the functional substance is prolonged. Because the functional cavity is arranged at the downstream of the drainage unit, the damage of an upstream element caused by the upstream of the drainage valve in the past is avoided. Because the arrangement is in the drainage unit low reaches, can carry out large tracts of land washing to the dirty face of stool pot along with a large amount of water tank drainage water, overcome some schemes and can't carry out the drawback that large tracts of land was washd to the stool pot. Because the time that the accessible adjustment second waterway channel's structure changed the function thing and flowed out can be controlled and functional thing is filled into again in the stool pot washing later stage, has avoided the waste, has prolonged the function thing live time. For the toilet with the water seal water replenishing valve, the water replenishing joint is reserved, so that the concentration of functional substances in the water storage part of the toilet is conveniently improved.

Detailed Description

The contents of the present invention will be explained below by referring to 4 examples.

For convenience of explanation, the operation schematic diagram of the valve body installed in the toilet water tank is described, but except that fig. 1 is a schematic diagram of the whole toilet, other figures are only described by the structure around the valve body, and other parts are not repeatedly described.

The structure of the first embodiment will be described with reference to fig. 1 and 2, and fig. 3 shows a timing chart of each water flow.

The closestool body is provided with a water tank 30, a basin water inlet 31, a basin water outlet 32, a bottom water inlet 33, a bottom water outlet 34 and a trap 35,

the drain valve includes: a drainage unit 10, a first waterway channel 11, a second waterway channel 12, and an air vent 17, wherein the second waterway channel 12 includes an inlet 121, an inlet pipe 122, a function cavity water inlet 123, a function cavity 124, a function cavity water outlet 125, a function cavity water outlet pipe 126, and a function liquid outlet 127,

before the drain valve drains, the water tank level is at TL and the functional cavity level is at SL.

When the drain valve is opened, the water in the tank is discharged to the dirt-bearing surface where the ceramic contacts with the dirt through the first water passage 11, reaches the dirt-bearing surface at time T0 as water flow MF which does not flow through the second water passage and reaches the dirt-bearing surface, and ends at time T1. And a part of water in the water tank flows into the function cavity 124 through the inlet 121, the inlet pipeline 122, the function cavity water inlet 123, the function cavity water level SL is maximally raised to SLS, the water flow is mixed with the function substance in the function cavity 124 and then flows through the function cavity water outlet 125, the function cavity water outlet pipe 126 and the function liquid outlet 127 to serve as water flow DW which flows through the second drainage channel and reaches the dirt bearing surface, the water flow DW reaches the dirt bearing surface at T11, the function cavity water level SL is restored to the initial value at the time point of T21, and the water flow DW which flows through the second drainage channel and reaches the dirt bearing surface is stopped. In this process, since the tank level is always lower than the initial level, the trapway fill water flow RF also flows until the tank level TL returns to the initial height at time T3.

In the time period from T0 to T11, the large-flow water flow of the water tank cleans the dirt bearing surface in a large area. In the time period from T11 to T1, large-flow water in the water tank carries functional objects to clean a large area of a dirt bearing surface, a large amount of water stops flowing in the time period from T1, the process of discharging water from the toilet is stopped, and the water enters the process of injecting water into a trap. The functions injected after T1 are all present in the toilet bowl for a longer time with the trap water. During the time period from T1 to T21, the trap refill water flow RF with small flow rate and the functional substance-containing water flow overflowing the functional chamber are washed and the trap is filled with water with a small covered surface. During the time period T21 to T3, the trapway refill water stream RF cleans the dirty side to a lesser extent and fills the trapway with water.

The water inlet quantity can be controlled by the waterway diameter of the variable inlet 121, the inlet pipeline 122 and the functional cavity water inlet 123, the water discharging speed can be controlled by changing the drift diameters of the functional cavity water outlet 125, the functional cavity water outlet pipe 126 and the functional liquid outlet 127, the time point of the functional substance flowing out of the functional liquid outlet 127 can be controlled by changing the length of the functional cavity water outlet pipe 126, and the quantity of the injected functional substance can be controlled by changing the height difference between the initial functional cavity water level SL and the water tank water level TL. The above structure is configured, so that the time difference from the initial flowing of the water in the water tank to the functional object flowing out of the functional liquid outlet 127 through the first waterway channel 11 is more than 1 second, and more functional objects are prevented from being taken away in the early stage and the siphoning process of the closestool.

Referring to fig. 3 and 5, the second embodiment, compared to the first embodiment, will further increase the concentration of functional substances in the toilet bowl water by delaying the flow time of the water flow DW flowing through the second drainage channel to the dirt receiving surface until after the flow of the trapway fill water flow RF is stopped.

The second embodiment will be described with reference to fig. 4 and 5.

The toilet body portion is the same as the first embodiment and will not be described here.

The drain valve includes: the water-saving device comprises a water drainage unit 10, a first water channel 11, a second water channel 12, a water supplementing channel joint 13, a functional object operation rod 14 and a vent 17, wherein the second water channel 12 comprises an inlet 121-2, an inlet pipeline 122-2, a functional cavity water inlet 123-2, a functional cavity 124-2, a functional cavity water outlet 125-2, a functional cavity water outlet pipe 126-2 and a functional liquid outlet 127-2.

Before the drain valve drains, the water tank level is at TL and the functional cavity level is at SL. When the drain valve is opened, since the tank level is always lower than the initial level, the trap refill water stream RF also flows until the tank level TL returns to the initial level at a time point T3. The water in the tank is discharged to the dirt receiving surface through the first water passage 11, reaches the dirt receiving surface at time T0 as water flow MF which does not flow through the second water passage and reaches the dirt receiving surface, and ends at time T1. And a part of water in the water tank flows into the functional cavity 124-2 through the inlet 121-2, the inlet pipeline 122-2 and the functional cavity water inlet 123-2. And water which is part of the trap water replenishing flow RF reaches the function cavity 124-2 through the water replenishing channel joint 13 and the fork port 132, the water level SL of the function cavity rises to SLS at the maximum, the water flow is mixed into a function substance in the function cavity 124-2, and the function substance passes through the function cavity water outlet 125-2, the function cavity water outlet pipe 126-2 and the function liquid outlet 127-2 to reach the dirt bearing surface as water flow DW which flows through the second drainage channel at T11, and the water level SL of the function cavity is restored to the initial value at the time point of T21 and then the water flow DW which flows through the second drainage channel to reach the dirt bearing surface is stopped. Since the functional chamber water level SL does not return to the initial height until T3 has ended, time T21 is later than T3.

In the time period from T0 to T11, the large-flow water flow of the water tank cleans the dirt bearing surface in a large area. In the time period from T11 to T1, large-flow water in the water tank carries functional objects to clean a large area of a dirt bearing surface, a large amount of water stops flowing in the time period from T1, the process of discharging water from the toilet is stopped, and the water enters the process of injecting water into a trap. The functions injected after T1 are all present in the toilet bowl for a longer time with the trap water. During the time period from T1 to T3, the trap refill water flow RF with small flow rate and the functional substance-containing water flow overflowing the functional chamber are washed and the trap is filled with water with a small covered surface. During the time period T3 to T21, the trapway refill water flow RF stops and only a small amount of functional chamber overflow flows to the trapway.

Like the first embodiment, the configuration of the second waterway passage 12 may vary the amount/time of outflow of the functional substance, etc. However, compared to the first embodiment, the second embodiment can also achieve the purpose of adjusting the function by adjusting the flow-through diameters of the water supply channel outlet 131 and the fork 132.

In this example, there is also a function operating bar 14 to perform physical operations on the function, such as touching to sense function residue, flipping the function, stirring, moving the function, avoiding touching by the user's hand. The functional cavity 124-2 is still replaced after use, and the functional object operating rod 14 is not required to be cleaned.

Referring to fig. 3 and 7, in contrast to the first embodiment, T11 in the third embodiment is very close to T1, which is reflected in the flow: when the water in the toilet tank is about to be flushed, the functional objects are discharged to the dirt bearing surface.

A third embodiment will be described with reference to fig. 6 and 7.

The drain valve includes: the water drain device comprises a water drain unit 10, a first waterway channel 11, a second waterway channel 12, a water supplementing channel joint 13 and a vent 17, wherein the second waterway channel 12 comprises an inlet 121-3, an inlet pipeline 122-3, a function cavity water inlet 123-3 and a function cavity 124-3.

When the drain valve is opened, since the tank level is always lower than the initial level, the trap refill water stream RF also flows until the tank level TL returns to the initial level at a time point T3. The water in the tank is discharged to the dirt receiving surface through the first water passage 11, reaches the dirt receiving surface at time T0 as water flow MF which does not flow through the second water passage and reaches the dirt receiving surface, and ends at time T1. In the process, a part of water flows into the functional cavity 124-3 through the inlet 121-3, the inlet pipeline 122-3 and the functional cavity water inlet 123-3, the water flows into the functional cavity 124-3 to flow out of the functional cavity 124-3 along with the reduction of the water level of the water tank, and the water carrying the functional substance is guided to the dirt bearing surface through the functional cavity water inlet 123-3, the inlet pipeline 122-3 and the inlet 121-3. The trap refill water flow RF flows into the toilet trap through the refill joint 13 and the refill outlet 131.

Like the first embodiment, the configuration of the second waterway passage 12 may vary the amount/time of outflow of the functional substance, etc.

Referring to fig. 5 and 10, in the fourth embodiment, compared with the second embodiment, the flow DW of the water flowing through the second drainage channel to the dirt receiving surface between T11 and T1 is larger. The device is embodied on a closestool, and the instantaneous throwing amount is large.

A fourth embodiment will be described with reference to fig. 8, 9, and 10.

The drain valve includes: the drainage unit 10, the first waterway channel 11, the second waterway channel 12, the water replenishing passage joint 13, the air vent 17 and another drainage unit 101. The second waterway channel 12 comprises an inlet 121-4, a function cavity 124-4, a function cavity water outlet 125-3, a function cavity water outlet pipe 126-3 and a function liquid outlet 127-4.

When the drainage unit 10 and the other drainage unit 101 are opened simultaneously, the water in the water tank is drained to the dirt bearing surface through the first waterway channel 11 and the second waterway channel 12, because the second waterway channel 12 has a longer pipeline length than the first waterway channel 11 and has more air in the initial stage in the second waterway channel 12, the water flow DW flowing through the second drainage channel and reaching the dirt bearing surface reaches the dirt bearing surface later than the water flow MF not flowing through the second drainage channel and reaching the dirt bearing surface. When the tank level drops below the inlet 121-4, the water in the functional chamber 124-4 continues to flow to the dirt-bearing surface, but the flow rate decreases as the height decreases. As water is continually replenished into the functional chamber 124-4 through the prong 132, the flow rate of water out of the functional chamber 124-4 is eventually made equal to the flow rate of water out of the prong 132. When the water level in the water tank is restored to the original level at the time point T3, the trap refill water flow RF is stopped, and the water flow DW flowing through the second drainage channel to the soil-receiving surface is also stopped with a delay.

In the time period from T0 to T11, the large-flow water flow of the water tank cleans the dirt bearing surface in a large area. In the time period from T11 to T1, large-flow water in the water tank carries functional objects to clean a large area of a dirt bearing surface, a large amount of water stops flowing in the time period from T1, the process of discharging water from the toilet is stopped, and the water enters the process of injecting water into a trap. The functions injected after T1 are all present in the toilet bowl for a longer time with the trap water. During the time period from T1 to T3, the trap refill water flow RF with small flow rate and the functional substance-containing water flow overflowing the functional chamber are washed and the trap is filled with water with a small covered surface. In the time period from T3 to T21, residual water in the functional cavity 124-4, the functional cavity water outlet 125-4 and the functional cavity water outlet pipe 126-4 flows to the dirt bearing surface.

The present application has been described above in a brief summary with reference to specific embodiments, but the present application is not limited to these specific embodiments. That is, as long as the features of the present invention are provided, the technique of appropriately changing the embodiments by those skilled in the art is also included in the scope of the present invention, and it is within the scope of the present application to appropriately change the elements, their arrangement, materials, conditions, shapes, dimensions, and the like, and for example, to change the water tank to be open or closed, to simply change the position of the second passage, to change the diameter of the pipe to be reduced or deformed to generate a pressure difference instead of reducing the diameter, to change the flushing device to be a valve or a pump, to change the flushing object to be a concentrated agent, and the like in the above-described embodiments.
