Description

Technical Field

[0001] This invention relates to the field of bathtub wastewater treatment technology, specifically a bathtub with impurity filtration function. Background Technology

[0002] A bathtub is a plumbing fixture used for bathing or showering, usually installed in a home bathroom. Historically, most bathtubs have been rectangular. In recent years, with the increasing popularity of acrylic heated bathtubs, various shapes of bathtubs have begun to appear. The most common color for bathtubs is white, but other colors such as pink are also available. Most bathtubs have a drain at the bottom and a drain at the top to prevent overflow. Some have the water tap installed on the edge of the bathtub. In existing bathtub technology, the drain outlet is usually equipped with only a simple hair filter. Its filtration accuracy is low, and it can only intercept coarse and long hairs and large impurities. It is difficult to effectively intercept tiny pollutants such as dander, fine fibers or abrasive particles, so that these pollutants can directly enter the municipal drainage system, thereby increasing the burden on the pipe network and sewage treatment plants. Summary of the Invention

[0010] Optionally, two receiving cavities are opened on each side of the top of the bathtub body. A bottom plate is slidably connected to the inner wall of both sides of the bathtub body. An inner rod is fixed to the top of the bottom plate. An outer tube is slidably connected to the surface of the inner rod. A handrail is fixed to the top of the outer tube. The vertical part of the handrail is located inside the receiving cavity and is slidably connected to the receiving cavity. The outer tube has two snap-fit ​​interfaces on its surface.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This bathtub with impurity filtration function stores hot water inside the foot mat, which slows down the rate at which the water temperature in the bathtub body drops, improving the comfort of bathing. After bathing, the hot water stored in the foot mat can be reused to rinse the user's body or clean the inside of the bathtub body after it cools down, thereby reducing water consumption.

[0014] 2. This bathtub with impurity filtration function uses a water pump assembly to pump water from the inside of the bathtub body through the water pipe and suction plate. This causes the water inside the bathtub body to continuously flow towards the sides of the bathtub body near the suction plate, that is, the water inside the bathtub body to continuously flow towards the side filter frame. This causes dander and other impurities to concentrate in the side filter frame, thereby improving the filtration efficiency of the side filter frame for dander and impurities. At the same time, the filtered wastewater below the side filter frame can be discharged into the drain tank through the drain channel and then discharged. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1

[0019] Please see Figure 1-13 A bathtub with impurity filtration function includes a bathtub body 1. A faucet assembly 12 is fixed to the top of one end of the bathtub body 1. Side brackets 2 are fixed to the bottom of both sides of the inner cavity of the bathtub body 1. An embedded groove 22 is opened below the opposite side of the two side brackets 2. A first spring 23 is fixed inside the embedded groove 22. A sealing block 24 is fixed to one end of the first spring 23. The sealing block 24 is slidably sealed to the embedded groove 22. Movable brackets 3 are slidably connected to both sides inside the bathtub body 1. The two ends of the movable brackets 3 abut against the two side brackets 2. A first sealing tube 25 is slidably connected to the inner wall of the vertical part of the movable bracket 3. An L-shaped card block 26 is fixed to the surface of the first sealing tube 25. An elastic rope 27 is fixed to the surface of the L-shaped card block 26. Elastic rope 27 is located inside the first sealing tube 25, and one end of elastic rope 27 is fixed to the movable bracket 3. One end of L-shaped block 26 is slidably connected to the inner groove 22. The L-shaped block 26 is inclined at one end near the sealing block 24 and away from the faucet assembly 12. A foot pad 32 is fixed on the top of a movable bracket 3 near the faucet assembly 12. A limiting groove 33 is opened on the top of the foot pad 32. A water inlet 34 is opened at the bottom of the limiting groove 33. A movable pad 36 is slidably connected inside the limiting groove 33. A drain groove 6 is opened on the bottom of the bathtub body 1 near the faucet assembly 12. A foot pad 11 is fixed on the bottom of the bathtub body 1. A side filter rack 21 is slidably connected inside the side frame 2. A pad plate 201 is fixed inside the side frame 2 below the side filter rack 21. A seat cushion 31 is fixed on the top of a movable bracket 3 away from the faucet assembly 12. A water outlet 35 is opened on one side of the foot pad 32. The bottom of the movable pad 36 is fixed with a first connector 37, which is slidably connected to the water inlet 34. The bottom of the first connector 37 is located inside the foot pad 32. A second connector 38 is fixed to the surface of the first connector 37 near the water outlet 35. A first seal 381 is fixed to the end of the second connector 38 near the water outlet 35. The first seal 381 abuts against the inner wall of the foot pad 32 near the water outlet 35. A second spring 39 is fixed to the surface of the first connector 37. One end of the second spring 39 is fixed to the inner wall of the foot pad 32. In actual use, when a user needs to take a bath, the two movable brackets 3 are first placed inside the bathtub body 1, so that the seat cushion 31 is placed away from the faucet assembly 12 and the foot pad 32 is placed close to the faucet assembly 12. Then, according to the user's usage habits, the two movable brackets 3 are slid, so that the movable brackets 3 drive the first sealing tube 25 and the L-shaped card block 26 to slide along the opposite side of the two side brackets 2. During the sliding process, the L-shaped card block 26 continuously contacts each sealing block 24. Since the L-shaped locking block 26 is located near the end of the sealing block 24 and is inclined on the side away from the faucet assembly 12, when the L-shaped locking block 26 slides away from the faucet assembly 12, the L-shaped locking block 26 continuously pushes against the sealing block 24 and enters the interior of each embedded groove 22 it passes through. During the continuous movement, the port of the embedded groove 22 pushes the inclined side of the L-shaped locking block 26 in the opposite direction, so that the L-shaped locking block 26 is retracted. This ensures that the L-shaped locking block 26 can move away from the faucet assembly 12 without obstruction, while ensuring that the moving bracket 3 is not moved towards the faucet assembly 12 by external force. When the two moving brackets 3 move to the appropriate position, the movement can be stopped. Then, the user can fill the bathtub body 1 with hot water through the faucet assembly 12 and then enter the bathtub body 1. At this time, the user's head can face the seat cushion 31 and the user's feet can face the foot pad 32. The user can lie down. Since the positions of the two movable supports 3 are adjusted, the user's buttocks can be supported by the seat cushion 31 and the user's feet can be supported by the foot pad 32 after lying down. This prevents the user from sliding down after lying in the bathtub body 1 and improves the stability of the user's body while taking a bath. Furthermore, when storing hot water inside the bathtub body 1, the user can move the movable pad 36, causing the movable pad 36 to move the first connecting piece 37 toward the second spring 39, thereby opening the water inlet 34. Hot water can then enter the foot pad 32 through the water inlet 34 and accumulate. When the foot pad 32 is full of hot water, the pressure on the movable pad 36 can be released, causing the movable pad 36 and the first connecting piece 37 to reset under the action of the second spring 39. This allows the movable pad 36 to close the water inlet 34 again, thus ensuring that the hot water in the foot pad 32 is isolated from the hot water in the bathtub body 1. When a user is taking a long bath, the water temperature inside the bathtub body 1 will gradually decrease. Due to the effect of hot air rising and cold air falling, the temperature near the bottom of the bathtub body 1 is usually lower than the temperature at the top. In particular, the foot pad 32 is close to the drain area, and its temperature drops even faster. Therefore, when the user's feet are placed on the surface of the foot pad 32, the hot water inside the foot pad 32 can slow down the rate at which the hot water temperature inside the bathtub body 1 around the foot pad 32 drops, thus reducing the rate at which the water temperature around the user's feet drops. This can increase the overall body temperature by extending the water temperature around the feet, thereby improving the comfort of long-term bathing. When the bath is finished and the bathtub body 1 is drained, as the sewage in the bathtub is gradually discharged, the skin flakes or small debris located on both sides of the water can enter the interior of the side filter frame 21 and be filtered by the side filter frame 21. This allows the sewage in the bathtub body 1 to be filtered by the side filter frame 21 at the same time as it is discharged through the drain trough 6, thereby improving the efficiency of the present invention in filtering skin flakes or small debris, reducing the filtration pressure of the drain trough 6, and reducing the amount of skin flakes and other debris in the sewage discharged from the bathtub body 1, thereby reducing the pressure on municipal drainage and sewage treatment plants. Furthermore, after the wastewater in the bathtub body 1 is drained, the movable bracket 3 under the foot pad 32 can be adjusted again to move away from the faucet assembly 12. Before the L-shaped locking block 26 enters the next recessed groove 22, the movable bracket 3 is removed. At this time, the foot pad 32 is in a completely independent state. Then, the movable pad 36 is moved towards the second spring 39 again, so that the movable pad 36 drives the first connecting piece 37 to move towards the second spring 39. This causes the first connecting piece 37 to drive the second connecting piece 38 and the first sealing piece 381 to move towards the second spring 39. During the movement, the first sealing piece 381 loses its seal on the water outlet 35, thus opening the water outlet 35. At this time, the warm water collected in the foot pad 32 can be discharged to the outside through the water outlet 35. The warm water in the foot pad 32 is isolated from the water flow in the bathtub body 1, meaning the water in the foot pad 32 is in a clean state. Therefore, the warm water in the foot pad 32 can be used to clean the bathtub body 1, or for the user to shower after bathing, thereby reducing water consumption and playing a role in environmental protection and energy saving.

[0020] It should be noted that all devices in this invention are controlled by a controller, as specified in the appendix to the specification. Figure 12 It can be seen that the opening of the water inlet 34 is not located in the middle of the foot pad 32, as indicated by the attached... Figure 11 It is known that the water outlet 35 is located on the side away from the second spring 39, that is, the water inlet 34 and the water outlet 35 are at different distances from the second spring 39. Therefore, during the process of the movable pad 36 driving the first connecting member 37, the second connecting member 38 and the first sealing member 381 to move towards the second spring 39, the water outlet 35 first loses the seal of the first sealing member 381 and opens, and then the water inlet 34 loses the seal of the movable pad 36 and opens. This allows the user to control the water outlet 35 to open independently, and thus the user can hold the foot pad 32 and point the water outlet 35 at himself to rinse or rinse the inside of the bathtub body 1. The foot pad 32 can be made of 304 stainless steel with a double-layer vacuum structure, which can effectively slow down the rate at which the water temperature inside the bathtub body 1 drops.

[0021] Example 2

[0022] The bathtub body 1 has a first inner groove 4 on both sides of its surface. A water pipe 41 is fixed inside the first inner groove 4. An outer sealing plate 42 is fixed on both sides of the bathtub body 1. A mounting bracket 43 is fixed inside the bathtub body 1 at one end near the faucet assembly 12. A flip plate 44 is hinged to the top of the mounting bracket 43. A water pump assembly 45 is fixed inside the flip plate 44. A water suction plate 411 is fixed to one end of the water pipe 41. A snap-fit ​​plate 46 is slidably connected to the top of the mounting bracket 43. A filter plate 47 is fixed to the end of the snap-fit ​​plate 46 away from the faucet assembly 12. Two receiving cavities 5 are opened on each side of the top of the bathtub body 1. The inner walls of the two sides of the bathtub body 1 are slidably connected to the bottom plate 51. The top of the bottom plate 51 is fixed with an inner rod 52. The surface of the inner rod 52 is slidably connected with an outer tube 53. The top of the outer tube 53 is fixed with a handrail 54. The vertical part of the handrail 54 is located inside the receiving cavity 5 and is slidably connected with the receiving cavity 5. The surface of the outer tube 53 has two locking interfaces 55. The inner rod 52 has a second inner groove 56 on the side near the locking interface 55. The second inner groove 56 is fixed with a third spring 57. One end of the third spring 57 is fixed with a top rod 58. The top rod 58 is slidably and sealingly connected with the second inner groove 56 and slidably connected with the locking interface 55. Specifically, based on Embodiment 1, when the user is taking a bath in the bathtub body 1, the water pump assembly 45 can be started by the controller. The water pump assembly 45 will draw water from the suction pipe 41. Since one end of the suction pipe 41 is connected to the suction plate 411, the water pump assembly 45 will draw warm water from the bathtub body 1 into the water pump assembly 45 through the suction plate 411. The water will be heated by the heating module of the water pump assembly 45. After heating, the hot water will be released back into the interior of the bathtub body 1 through the faucet assembly 12. When the faucet assembly 12 releases the secondary heated hot water, the hot water flows over the surface of the snap plate 46. Impurities such as skin flakes in the secondary heated hot water can be initially filtered by the filter plate 47. As the hot water in the bathtub body 1 continues to circulate, and in conjunction with the hot water stored in the foot pad 32 in Embodiment 1, the water temperature in the bathtub body 1 can be further maintained. This not only improves the comfort of bathing, but also continuously filters impurities such as skin flakes in the bathtub body 1 during the hot water circulation process, thereby improving the cleanliness of the water flow during bathing. Furthermore, when the user needs to get up or get out of the bath, the top rod 58 can be pressed to retract into the second inner groove 56, allowing the outer tube 53 to slide and adjust unimpeded on the surface of the inner rod 52. Then the outer tube 53 can be stretched, causing the armrest 54 to extend outward from the inside of the receiving cavity 5. At the same time, the bottom plate 51 can be pulled out from the inside of the bathtub body 1. Since the vertical part of the armrest 54 is located inside the receiving cavity 5, the space in which the bottom plate 51 can be pulled out is limited. This design provides ample space for the user's hands to grip the inner rod 52, outer tube 53, and handrail 54. The foot pads 32 provide support for the feet, preventing slippage when the user gets up, making it easier and more stable for them to stand up. Furthermore, when exiting the bathtub body 1, the user can grip the horizontal part of the handrail 54, further enhancing the safety of entering and exiting the bathtub body 1.

[0023] It should be noted that the water pump assembly 45 consists of a hose, a silent water pump, and a heating module. The heating module can be selected to be heated by an electric heating element, that is, the electric heating element is placed in an independent box. The water pump assembly 45 draws warm water to the hose through the water suction plate 411 and pumps it into the box. After being heated, it enters the two independent faucets in the faucet assembly 12 through the hose again. All of the above are existing technologies, and the present invention will not elaborate further. When the water pump assembly 45 is started, the warm water in the bathtub body 1 is pumped to the faucet assembly 12 through the water pipe 41 and the suction plate 411. The water in the bathtub body 1 flows towards the suction plate 411, which in turn causes the water in the bathtub body 1 to carry skin flakes and other impurities towards the side filter frame 21. This allows the skin flakes and impurities in the sewage in the bathtub body 1 to settle into the side filter frame 21 more efficiently and be filtered, thereby improving the filtration efficiency of the side filter frame 21. At the same time, when the hot water flows back through the filter plate 47, the water flows from a high place into the water, impacting the water in the bathtub body 1, making the water ripple more widely. This causes the skin flakes and other impurities in the water to float to both sides faster, making it easier for them to enter the interior of the side filter rack 21 and be filtered.

[0024] Example 3

[0025] A second sealing pipe 7 is fixed on both sides inside the drain trough 6. A rebound device 71 is fixed at the bottom of the inner cavity of the second sealing pipe 7. A sealing column 72 is slidably connected inside the second sealing pipe 7. A water sealing plate 73 is fixed at the top of the sealing column 72. A bidirectional filter groove 74 is opened on both sides of the water sealing plate 73. A second sealing element 75 is fixed at the bottom of both ends of the water sealing plate 73. Drainage channels 76 are opened on the inner walls on both sides of the bathtub body 1, and the drainage channels 76 are connected to the drain trough 6. A bidirectional drain component 8 is fixed at the bottom of the bathtub body 1 below the drain trough 6. A drain pipe 81 is fixed at the bottom of the bidirectional drain component 8. The drain pipe 81 is connected to the drain trough 6 through the bidirectional drain component 8. A water storage tank 82 is provided at the bottom of the bathtub body 1. A docking groove 83 is provided on the side of the water storage tank 82 near the bidirectional drain component 8. The docking groove 83 is slidably connected to the bidirectional drain component 8. A limiting plate 84 is fixed on the inner wall of the bathtub body 1 near the water storage tank 82. The limiting plate 84 abuts against the water storage tank 82. Specifically, based on Embodiment 1 and Embodiment 2, when a user is taking a bath, since the positions of the two movable supports 3 are adjusted to a suitable position, and the user's buttocks are supported by the seat cushion 31 and the user's feet are supported by the foot pad 32, the user can choose a more stable and comfortable posture to lie inside the bathtub body 1. When a user is taking a bath, the foot pad 32 supports the user's feet or legs, keeping the user's feet or legs away from the water sealing plate 73. This prevents the user from accidentally touching the water sealing plate 73, thus preventing the activation of the rebound device 71 after the water sealing plate 73 is accidentally touched, thereby preventing accidental drainage and water waste. Meanwhile, when the bath is finished and drainage is needed, the user can put their feet under the foot pad 32 and the corresponding movable bracket 3, and step on the water sealing plate 73. This causes the water sealing plate 73 to drive the sealing column 72 to press the rebound device 71, thereby activating the rebound device 71. This causes the rebound device 71 to drive the sealing column 72 and the water sealing plate 73 to bounce upward, allowing the sewage in the bathtub body 1 to be discharged through the water sealing plate 73 and the bidirectional filter tank 74. During the sewage discharge process, the hair and other flocculent matter in the sewage can be filtered over a large area by the bidirectional filter tank 74, which avoids the bidirectional filter tank 74 from clogging and affecting the drainage efficiency. At the same time, after the sewage is filtered by the bidirectional filter tank 74, it enters the interior of the drainage tank 6 and then enters the interior of the bidirectional drainage component 8 through the drainage tank 6. When sewage enters the two-way drainage component 8, since the bottom of the two-way drainage component 8 is fixedly connected to the drainage pipe 81, and the drainage pipe 81 is connected to the building drainage system, and the two-way drainage component 8 is flat, that is, the opening area of ​​the two-way drainage component 8 facing the water storage tank 82 is larger than the pipe diameter area of ​​the drainage pipe 81, a large proportion of sewage in the two-way drainage component 8 is discharged into the interior of the water storage tank 82, while a small proportion of sewage is discharged into the building drainage system through the drainage pipe 81, and then enters the municipal drainage system, thereby relieving the pressure on the municipal drainage and the sewage treatment plant. At the same time, a small proportion of warm wastewater entering the house drainage system can reduce the pressure on the drainage pipes and reduce the temperature difference between the wastewater discharged when cleaning the bathtub body 1. That is, the temperature difference between the warm wastewater discharged from the bathtub body 1 and the cold water used to clean the bathtub body 1 reduces the impact on the drainage pipes, thereby reducing the probability of pipe aging caused by repeated impacts from temperature difference water flow, and also reducing the probability of water leakage caused by gaps due to thermal expansion and contraction of the pipes. With the combined use of the three filtration structures in Embodiments 1, 2, and 3, the pre-treated wastewater in the bathtub body 1 can be collected into the water storage tank 82, and then reused for subsequent cleaning and mopping, reducing water consumption and improving the environmental protection effect of the present invention.

[0026] It should be noted that the bottom of the inner cavity of the side frame 2 is hollow, that is, the hot water in the bathtub body 1 can enter the bottom of the inner cavity of the side frame 2 through the side filter 21. When the water sealing plate 73 is lifted, the water sealing plate 73 drives the second sealing member 75 to be lifted at the same time, so that the second sealing member 75 loses its seal on the drainage channel 76, allowing the sewage at the bottom of the inner cavity of the side frame 2 to be discharged into the interior of the drain trough 6 through the drainage channel 76 and into the interior of the bidirectional drain member 8, and then distributed to the water storage tank 82 for collection or distributed to the drain pipe 81 for discharge.

[0027] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
