Description

Technical Field

[0001] This invention relates to an automatic drainage device for a toilet, and more specifically, to an automatic drainage device for a toilet that automatically drains water from the tank when the toilet lid is closed after use and refills the tank when the lid is fully closed. Background Technology

[0002] Typically, toilets are equipped with a water tank. After using the toilet, the user supplies water to the inside of the toilet to discharge the waste into the septic tank. The water tank is equipped with: a water inlet pipe; and a drain cover. When the operating lever is operated, the drain cover connected to the connecting line is operated to open the drain outlet, thereby supplying water to the toilet.

[0003] For a conventional toilet with the configuration described above, when the user presses the operating lever after using the toilet, the operating rod connected to the operating lever will be lifted, and the connecting line connected to the operating rod will be pulled upward, thereby lifting the drain cover connected to the connecting line to open the drain outlet, introducing the water filled in the tank into the toilet, so as to discharge the feces to the septic tank side.

[0004] In addition, when the water tank is full and drains into the toilet bowl through the drain outlet, the raised drain cover falls down again to block the drain outlet, and the water tank automatically refills.

[0005] This traditional toilet uses water from the tank immediately after use to flush the waste to the septic tank side, thus preventing pollution or odors inside the toilet and maintaining a clean environment.

[0006] However, traditional toilet flushing devices are inconvenient because users need to press the operating lever every time they use them. Furthermore, children, being shorter, have difficulty operating the operating lever, which is installed at a relatively high position. Even if they manage to press the operating lever, it is difficult to maintain pressure on it for a certain period of time, thus making it difficult to easily drain water from the tank into the toilet bowl.

[0007] Furthermore, with traditional toilet drainage systems, if a user forgets to press the operating lever and leaves the bathroom, the feces will remain inside the toilet bowl, resulting in unhygienic toilet use and discomfort for other users.

[0008] According to existing technology, a toilet tank drainage device with authorized utility model No. 20-0229667 has been disclosed. In the toilet tank, which is equipped with a water inlet pipe and an opening and closing cover, and a drain pipe that supplies water to the toilet, a connecting body is attached to the upper end of a flush valve formed on one side of the drain pipe. A pipe is attached to the upper end of the connecting body, and a connection port is attached to the other side of the pipe. The connection port forms an air intake port, and the pipe is connected to the water inlet valve through an intake pipe.

[0009] In contrast to the prior art, the flushing valve formed on one side of the drain pipe can reduce noise at first, and the pipe connected to the flushing valve is made of soft synthetic resin, which can absorb noise at second time. It is also connected to the inlet valve through the suction pipe, thereby preventing noise generated during drainage or water storage.

[0010] However, while the existing technology, which has been granted utility model No. 20-0229667, can prevent noise generated during drainage to a certain extent, as mentioned above, it still does not solve the inconvenience of needing to press the operating lever to drain the water and the problem that children with weak grip strength cannot press the operating lever correctly. Furthermore, if the operating lever is not pressed, the water in the tank cannot be discharged to the toilet bowl side. Therefore, the problem caused by the user's negligence in not pressing the operating lever has not been solved.

[0011] As another example, a toilet automatic drainage device with authorized utility model number 20-0294080 is disclosed. In this toilet, which includes a water tank filled with a certain amount of water, a main body that uses the water in the water tank to discharge waste, and an opening and closing unit that opens and closes under certain conditions to discharge the water in the water tank into the main body, the device consists of a sensing unit installed in the main body to activate when a load is applied to the main body and then released, a drive unit installed in the water tank and operated to open and close the opening and closing unit, and a control unit that controls the operation of the drive unit based on an input signal input from the sensing unit. When the load applied to the main body is released due to the user getting up after using the toilet, the sensing unit detects this state and automatically drains the water in the water tank.

[0012] However, the aforementioned prior art not only imposes a cost burden on consumers because it requires additional sensor units, drive units, and control units to be installed on the toilet, but also relies on electricity because automatic drainage is achieved through electrical devices (sensor units, drive units, and control units), which can lead to problems such as inability to use the toilet in areas without power supply or in areas experiencing power outages.

[0013] Therefore, there is an urgent need for a technology that allows water in the tank to be automatically discharged into the toilet bowl simply by closing the toilet lid, without having to press an operating lever each time after using the toilet. Summary of the Invention

[0014] The problem the invention aims to solve

[0015] The purpose of this invention is to provide an automatic drainage device for a toilet, wherein after the user opens the toilet lid to use the toilet, the water in the tank is automatically discharged into the toilet by closing the toilet lid, so as to discharge the feces into the septic tank. When the toilet lid is completely closed, the water tank will be refilled with water, so it can be reused. No additional settings are required to use the existing toilet directly, thereby achieving the effect of saving costs economically, and no electricity is required.

[0016] means for solving problems

[0017] As a means to achieve the above-mentioned objectives, the automatic drainage device of the toilet of the present invention comprises a toilet consisting of the following components: a toilet bowl for a user to use; a toilet bowl cover for covering and closing the upper end of the toilet bowl or for opening the upper end of the toilet bowl by lifting it from the upper end of the toilet bowl; a water tank for storing water; and a drain cover located at the inner bottom of the water tank to drain water filled in the water tank into the inside of the toilet bowl or to block water in the water tank from draining into the inside of the toilet bowl. The automatic drainage device of the toilet includes: a first operating part connected to a drain cover disposed at the bottom of the water tank; and a second operating part connected to the toilet lid. When the toilet lid is opened towards the water tank to open the upper part of the toilet, and then the toilet lid is closed towards the upper part of the toilet after being attached to the first operating part, the first operating part is pulled, causing the drain cover to rise and open in a hinged manner, thereby allowing water from the water tank to drain into the inside of the toilet. When the toilet lid is completely closed to cover the upper part of the toilet, it separates from the attached first operating part, causing the drain cover, which was opened by pulling the first operating part, to fall down in a hinged manner, thereby blocking the drainage from the water tank.

[0018] Furthermore, the first operating unit is configured with: an operating cable portion, one side of which is connected to the drain cover of the water tank, and the other side located on the outside of the water tank; and a first magnetic body, which is connected to the other side of the operating cable portion located on the outside of the water tank. The second operating unit is configured with: a second magnetic body, which is fixed to the outer surface of the toilet seat by an adhesive method, and is located at a position corresponding to the first magnetic body when the toilet seat is opened in a hinged manner to open the upper end of the toilet; and an adhesive portion, one side of which is attached to the second magnetic body, and the other side of which is attached to the outer surface of the toilet seat, so as to fix the second magnetic body to the toilet seat by an adhesive method.

[0019] Furthermore, the first or second magnetic body is composed of magnets, which attract and adhere to each other under the action of magnetic force when they are close to each other.

[0020] Furthermore, one of the first magnetic body or the second magnetic body is made of a magnet, while the other is made of a metal plate, which is attracted and adhered to by the magnetic force of the first magnetic body or the second magnetic body made of a magnet.

[0021] Furthermore, the first magnetic body of the first operating part is provided with a fixing part that snaps onto and fixes the other side of the operating wire part.

[0022] Furthermore, a position setting unit is provided, into which the operation wire of the first operation unit is embedded to guide the first magnetic body of the first operation unit to be positioned in the center of the water tank. Thus, when the first magnetic body of the first operation unit is located in the center of the upper end of the toilet tank and the toilet lid is closed, the traction force of the first operation unit is maximized by the second magnetic body of the second operation unit attached to the first magnetic body of the first operation unit.

[0023] Invention Effects

[0024] This invention achieves automatic drainage in the following way: No lever-operated pressing action is required. Simply lifting the toilet lid from the top of the toilet bowl towards the tank and then closing it automatically drains the water from the tank into the toilet bowl. Therefore, not only adults but also children with weak grip strength can easily drain the water from the tank into the toilet bowl, making waste disposal after using the toilet more convenient. Furthermore, simply closing the toilet lid after opening drains the water from the tank into the toilet bowl, allowing waste to be discharged into the septic tank. Even if the user neglects to press the lever, waste disposal can still be completed, maintaining the cleanliness of the toilet bowl and the entire bathroom. Moreover, due to the simple structure of the device, it can be easily attached to existing toilet seats, resulting in low cost and significantly improved installation and usability. It is also applicable to various toilet lever types, including push-button levers, flush valve types, push-button valve types, and handle-type levers. Attached Figure Description

[0035] In addition to the objectives described above, other objectives and features of the present invention will be clearly presented below through the description of embodiments with reference to the accompanying drawings.

[0036] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art. Terms as defined in common dictionaries shall be interpreted as having the meaning consistent with the meaning in the relevant technical context, and shall not be interpreted in an idealized or overly formal sense unless expressly defined in this application.

[0037] In the following description, the automatic drainage device of the toilet according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

[0038] As shown in the figure, the present invention includes a toilet consisting of the following components: a toilet bowl 1 for a user to use; a toilet bowl cover 2 for covering and closing the upper end of the toilet bowl 1 or opening the upper end of the toilet bowl 1; a water tank 3 for storing water; and a drain cover 4 located at the bottom inner side of the water tank 3 to drain water from the water tank 3 into the inside of the toilet bowl 1 or to block water from draining from the water tank 3 into the inside of the toilet bowl 1. The automatic drainage device is configured with: a first operating part 10 connected to the drain cover 4 disposed at the bottom of the water tank 3; and a second operating part 20 detachably attached to the first operating part 10.

[0039] In the present invention with the above configuration, when the toilet lid 2 is connected to the toilet seat 2 and the toilet seat 2 is opened towards the water tank 3 to open the upper end of the toilet 1, when the toilet seat 2 is closed towards the upper end of the toilet 1 after being attached to the first operating part 10, the first operating part 10 attached to the second operating part 20 is pulled, thereby causing the drain cover 4 to rise in a hinged manner and opening the bottom of the water tank 3, so that the water in the water tank 3 is discharged into the inside of the toilet 1. When the toilet seat 2 is completely closed to cover the upper end of the toilet 1, the first operating part 10 attached to the second operating part 20 is separated, so that the drain cover 4, which was opened by the first operating part 10 being pulled, falls down in a hinged manner, thereby blocking the drainage of the water tank 3.

[0040] Therefore, after using the toilet, there is no need to operate the lever of the toilet. Simply closing the open toilet lid 2 will automatically allow the water in the tank 3 to flow into the toilet bowl 1 and discharge the feces into the septic tank. Thus, anyone can easily and conveniently discharge the water in the tank 3 into the toilet bowl 1, making the disposal of feces after using the toilet more convenient.

[0041] Furthermore, the water in the tank 3 can be automatically discharged into the toilet bowl 1 simply by closing the open toilet lid 2. Therefore, even if the user fails to press the lever due to negligence, the feces can still be disposed of, thus keeping the inside of the toilet and even the entire bathroom clean.

[0042] The first operation unit 10 of the present invention is configured with: an operation wire part 11, one side of which is connected to the drain cover 4 of the water tank 3 and the other side is located outside the water tank 3; and a first magnetic body 12, which is connected to the other side of the operation wire part 11 located outside the water tank 3.

[0043] At this time, the operating wire section 11 can be a wire section made of iron wire, or it can be formed into a rope-like structure made of synthetic resin (such as a guitar string).

[0044] The second operating part 20 of the present invention is provided with: a second magnetic body 21, which is fixed to the outer surface of the toilet lid 2 by means of attachment and is located at a position corresponding to the first magnetic body 12 when the toilet lid 2 is opened by means of hinge to open the upper end of the toilet 1; and an attachment part 22, which is attached to the second magnetic body 21 on one side and attached to the outer surface of the toilet lid 2 on the other side, so as to fix the second magnetic body 21 to the toilet lid 2 by means of attachment.

[0045] The second operating part 20 is attached to the upper surface of the toilet seat 2 by attaching the other side of the attachment part 22, which is attached to the first magnetic body 12, to the toilet seat 2. At this time, there is no limitation on the method of fixing the first magnetic body 12 to the attachment part 22 by attachment, and it can be made of any of double-sided tape, silicone pad or adhesive.

[0046] In the present invention configured as described above, after one side of the operating wire 11 is connected to the drain cover 4, the first magnetic body 12 of the first operating part 10 is located on the outside of the water tank 3 (i.e., the toilet cover 2 side), thereby positioning the first magnetic body 12 on the upper outside of the water tank 3.

[0047] Furthermore, the second magnetic body 21 can be attached to the toilet seat 2 using the attachment part 22 of the second operating part 20. At this time, regarding the position of the second magnetic body 21, as follows... Figure 3 As shown, when the toilet lid 2 is opened to the upper side to open the upper end of the toilet 1, it can be positioned and attached to the first magnetic body 12.

[0048] For the present invention configured as described above, such as Figure 3 As shown, when the toilet lid 2 is opened to the upper side to open the upper end of the toilet 1 during toilet use, the first magnetic body 12 and the second magnetic body 21 adhere to each other under the action of magnetic force.

[0049] After using the restroom, such as Figure 4 As shown, when the toilet lid 2 is placed over the upper end of the toilet 1, the second magnetic body 21 descends over the toilet lid 2 on the upper side of the toilet 1. At this time, the first magnetic body 12 attached to the second magnetic body 21 is pulled under the action of magnetic force, thereby the operating wire part 11 connected to the first magnetic body 12 on the other side is pulled along with the first magnetic body 12.

[0050] As described above, when the operating cable 11 is pulled, the drain cover 4 connected to one side of the operating cable 11 is lifted upwards to drain the water from the tank. Water is supplied to the toilet bowl 1, discharging the waste into the septic tank.

[0051] In addition, such as Figure 5 As shown, when the toilet lid 2 is continued to be placed on the upper side of the toilet 1, the first magnetic body 12 of the first operation part 10, which is attached to the second magnetic body 21 of the second operation part 20, separates from the second magnetic body 21. This is because the operation wire part 11 connected to the first magnetic body 12 on the other side can no longer be pulled due to its limited length, causing the first magnetic body 12 to separate from the second magnetic body 21.

[0052] As described above, when the first magnetic body 12 separates from the second magnetic body 21, as Figure 2 As shown, due to the weight of the drain cover 4, which is connected to one side of the operating wire section 11 and is lifted upwards, the drain cover 4 naturally falls down, blocking the drainage of the water tank 3, and as described above, water is supplied to the water tank 3, which was blocked from draining due to the drain cover 4, and the tank is filled again.

[0053] In this invention, the action of opening the toilet lid 2 from the upper end of the toilet bowl 1 to open it or closing the toilet lid 2 to close the upper end of the toilet bowl 1 is repeatedly achieved, as shown in the example. Figures 2 to 5 As shown, after the water in the tank 3 is discharged into the toilet bowl 1, the drainage of the tank 3 is blocked and the water is refilled. Therefore, after using the toilet, the water in the tank 3 can be automatically discharged into the toilet bowl 1 without the need to operate an additional lever.

[0054] The first magnetic body 12 of the first operation part 10 of the present invention may be configured with a fixing part 13 that snaps onto and fixes the other side of the operation wire part 11.

[0055] At this time, the fixing part 13 can be welded to the back of the first magnetic body 12, or the fixing part 13 can be attached to the first magnetic body 12 by means of, for example, glue. Since the fixing part 13 is provided on the first magnetic body 12 as described above and the other side of the operating wire part 11 is connected to the fixing part 13, when the first magnetic body 12 attached to the second magnetic body 21 is pulled due to the action of closing the toilet lid 2, the operating wire part 11 can be prevented from separating from the first magnetic body 12, so that it is easy to open the drain cover 4 inside the water tank 3 to realize drainage into the toilet 1.

[0056] In this invention, a position setting unit 30 is provided, in which the operation wire part 11 of the first operation part 10 is embedded, and is used to guide the first magnetic body 12 of the first operation part 10 to be positioned at the center a of the water tank 3.

[0057] At this time, the position setting part 30 is provided with a wire part guide part 31 for the operation wire part 11 to be inserted, and is provided with double-sided adhesive tape 32 for fixing the position setting part 30 to the water tank 3 by means of attachment.

[0058] The wire guide portion 31 of the position setting unit 30 can be formed as follows: Figure 6 The through hole shown is arranged along the vertical length direction of the position setting part 30, or as... Figure 7 The groove shown is arranged along the vertical length direction of the position setting part 30.

[0059] As described above, by attaching the position setting part 30 to the center a of the water tank 3, as the first magnetic body 12 of the first operation part 10 is positioned at the position setting part 30 at the center a of the upper end of the water tank 3 of the toilet 1, the operation wire part 11 can be positioned at the center a side of the water tank 3. Therefore, when the toilet lid 2 opens the upper end of the toilet 1 and is lifted towards the water tank 3, the first magnetic body 12 and the second magnetic body 21 are in corresponding positions, thereby significantly improving the adhesion. Moreover, when the toilet lid 2 is closed, the second magnetic body 21 of the second operation part 20 attached to the first magnetic body 12 of the first operation part 10 can maximize the traction force of the first operation part 10.

[0060] Furthermore, even if the drain cover 4 located inside the water tank 3 is positioned on the bottom side of the inner side of the water tank 3 rather than in the center, the first magnetic body 12 of the first operating part 10 connected to the other side of the operating wire part 11 can be positioned in the center a of the water tank 3 by the position setting part 30. Therefore, the first magnetic body 12 and the second magnetic body 21 can be easily attached, and when the toilet lid 2 is closed, the action of pulling the first operating part 10 by the second magnetic body 21 of the second operating part 20 attached to the first magnetic body 12 of the first operating part 10 can significantly improve the opening performance of the drain cover 4 located at the bottom of the water tank 3.

[0061] Figure 9 and Figure 10 Examples of the configurations of the present invention are shown below. Figure 9 As shown, one side of the operating cable section 11 can be connected to the push valve type 101; or as... Figure 10 As shown, one side of the operating cable section 11 can be connected to the handle-type lever 102 for use, so it can be installed and used regardless of the type and structure of the existing toilet.

[0062] Figure 11 This illustrates another embodiment of the invention. A wire connecting rod 14 is disposed at the upper end of the drain cover 4; a pressure reducing valve body 15 is disposed along the periphery of the wire connecting rod 14; an elastic spring 16 is disposed inside the pressure reducing valve body 15. When the wire connecting rod 14 rises as the operating wire part 11 is pulled, the elastic spring 16 is compressed, and then when the pulling of the operating wire part 11 is released, the elastic spring 16 quickly returns to its original position.

[0063] In the present invention configured as described above, by opening the toilet lid 2, the first magnetic body 12 of the first operating part 10 and the second magnetic body 21 of the second operating part 20 are attached to each other. When the toilet lid 2 is closed after using the toilet, the operating wire part 11 is pulled, which drives the wire part connecting rod 14 inside the pressure reducing valve body 15 to rise, thereby lifting the drain cover 4 to supply water to the toilet 1 side. And due to the lifting action of the drain cover 4, the elastic spring 16 is compressed.

[0064] Furthermore, when the action of completely closing the open toilet lid 2 separates the attached first magnetic body 12 and second magnetic body 21 from each other, and the pulling action of the operating wire part 11 is released, the compression of the compressed elastic spring 16 is released, causing the raised drain cover 4 to fall based on the rapid reset of the elastic spring 16, thereby blocking drainage.

[0065] In addition, such as Figure 12 As shown, a guide tube 17 may also be provided around the periphery of the operating wire section 11 to guide the pulling force when the operating wire section 11 is pulled as the first magnetic body 12 of the first operating section 10 is pulled.

[0066] In addition, the bottom of the pressure reducing valve body 15 may be provided with a pressure reducing hole 18, which can be directly connected to the drain channel or the water outlet pipe E can be directly connected to the toilet.

[0067] In addition, the operating wire section 11 is provided with a stopper 40, which can be locked at the upper end of the water tank 3 when the toilet lid 2 is closed, so that the first magnetic body 12 and the second magnetic body 21 can be easily and conveniently separated.

[0068] As described above, due to the presence of the stop 40, when the second magnetic body 21 is lowered along with the toilet lid by closing the toilet lid 2, the pulling range of the first magnetic body 12 attached to the second magnetic body 21 can be limited, thereby making the first magnetic body 12 and the second magnetic body 21 easy and convenient to separate.

[0069] The first magnetic body 12 or the second magnetic body 21 of the present invention can be configured as magnets that are pulled and attached by magnetic force when they are close to each other. Furthermore, either the first magnetic body 12 or the second magnetic body 21 can be made of a magnet, while the other can be made of a metal plate, which is pulled and attached by the magnetic force of the first magnetic body 12 or the second magnetic body 21 made of a magnet.

[0070] Furthermore, in the operation wire section 11 located outside the water tank 3 of the first operation section 10 of the present invention, since the operation wire section 11 is tightly fitted to the water tank cover 3-1 without gaps, during the attachment and separation process of the first magnetic body 12 and the second magnetic body 21 connected to the operation wire section 11, the operation wire section 11 may be pulled outside the water tank 3, or it may become too tight because it cannot be pulled any further.

[0071] Therefore, as Figure 13 As shown, an elastic component 3-2 such as a silicone pad is attached to the inside of the water tank cover 3-1 to maintain a distance between the operating wire part 11 and the water tank cover, thereby making the process of the first magnetic body 12 and the second magnetic body 21 attached and separated more smoothly.

[0072] The elastic member 3-2 has the function of opening the gap to allow the operating wire part 11 to move smoothly, so it can be evenly attached to the three edges inside the water tank cover 3-1, or it can be attached to only one surface.

[0073] Furthermore, in this invention, during the process of attaching and separating the first magnetic body 12 and the second magnetic body 21 connected to the operating wire section 11, lateral movement may occur, and bouncing may occur due to the reaction force caused by the weight of the stop member 40. In this case, the position of the first magnetic body 12 may not be fixed, making it difficult to accurately attach the second magnetic body 21, which may hinder the easy achievement of automatic drainage. Therefore, as... Figure 14 As shown, by sleeved on the operating wire section 11 with a tube 11-1 of elastic material connected to the operating wire section 11, the bouncing phenomenon caused by left and right movement and reaction force can be prevented.

[0074] The material of the aforementioned operating cable tube 11-1 is not limited, but any flexible and bendable material is acceptable. One end of the operating cable tube 11-1 is attached to the inside of the water tank 3, and the other end is attached to the outside of the water tank 3, using double-sided tape or the like.

[0075] Furthermore, since the size and structure of each household toilet are different, the weight of the first magnetic body 12 and the weight of the stop member 40 are mechanically closely related during the process of attaching and separating the first magnetic body 12 and the second magnetic body 21: therefore, when the first magnetic body 12 is heavier, the stop member also needs to be heavier; when the first magnetic body 12 is lighter, the weight of the stop member also needs to be adjusted accordingly. Therefore, since the weight of the stop member 40 needs to be adjusted under different circumstances, a weight-adjustable form of the stop member 40 is more suitable for the purpose of this invention. As an example, the stop member 40 can be an openable and closable cylindrical shape filled with steel balls or the like. Each household can adjust the weight of the stop member 40 by placing steel balls inside the cylinder and adding or removing them as needed; this is also a method.

[0076] As described above, specific details and limited embodiments based on specific constituent elements and drawings have been presented in this invention. However, this is only provided to help to understand the invention more fully. The invention is not limited to the above embodiments, and any modifications and changes can be made based on this description by those skilled in the art.

[0077] Therefore, the concept of this invention should not be limited to the illustrated embodiments, and all modifications that are equivalent to or equivalent to the scope of the foregoing claims fall within the scope of this invention.
