Description

Technical Field

[0001] This invention relates to the field of household floor drain technology, specifically to an intelligent adjustable household floor drain device. Background Technology

[0002] Floor drains are an inconspicuous but essential device in everyday home appliances. They are important interface devices that connect the individual drainage pipes of each household to the central drainage pipe. They are also very important sanitary devices in every home. Their main function is to remove water from the indoor floor and prevent harmful gases from the pipe system from entering the room. Therefore, they must have good drainage capacity and good sealing effect to achieve the purpose of not only timely drainage of indoor sewage but also blocking toxic and harmful gases from the central drainage pipe.

[0003] With the development of technology and people's increasing pursuit of quality of life, smart homes are increasingly entering households. As an important barrier to protect the home environment and safeguard people's health, the intelligentization of floor drain devices has significant application value.

[0004] If floor drains are used too infrequently, the water in the water seal device of the floor drain system will dry out and lose its sealing effect. Therefore, choosing a safer and more reliable residential floor drain device plays a vital role in ensuring the quality of life and health of residents.

[0005] In existing technologies, residential floor drain sealing devices typically employ three main sealing methods: traditional water seal, mechanical seal, and a combination of mechanical and water seal. Traditional water seal devices utilize the water remaining in the drain's bend for sealing. my country's "Code for Design of Building Water Supply and Drainage" (GB50015-2003) clearly stipulates that the water seal height of water-sealed floor drains should be controlled at over 50mm to ensure effective sealing. However, due to the volatility of water, in daily household use, some floor drains with low usage frequency experience continuous evaporation of the sealing water during prolonged periods of inactivity, sometimes even drying out completely, thus losing their sealing effect. Mechanical devices use mechanical structures to seal the floor drain. While they typically perform well initially, with increased use, aging and damage severely affect the sealing performance. The combination of mechanical and mechanical seals aims to achieve better sealing and extend service life, demonstrating some application value. However, in current applications, the mechanical seal often neglects the importance of the water seal height, resulting in the drain not only failing to function as intended but also negatively impacting drainage and sewage disposal. Furthermore, the aforementioned sealing methods lack intelligence and cannot promptly discharge excess sewage. For example, Chinese patent CN212689164U discloses an odor-proof drain device, a mechanical-water seal combination. It uses a U-shaped water tank to store water and achieve a water seal layer, providing some odor prevention. However, it still cannot prevent the water seal layer from drying out and losing its sealing effect when the drain is not used for a long time, and its intelligence is also low.

[0006] Therefore, how to ensure the sealing effect of household floor drain devices while meeting the requirements for intelligentization is an urgent problem to be solved. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides an intelligent adjustable floor drain device for residential use.

[0008] This invention discloses an intelligent adjustable floor drain device for residential use, comprising:

[0009] The drain body has a receiving space containing a sealing liquid.

[0010] A drain pipe that connects to the receiving space and leaks into the sealing liquid;

[0011] A sealing assembly includes a sealing element and a sealing adjustment element, the sealing adjustment element being connected to the sealing element, the sealing element being located in the receiving space and covering the drain pipe, the sealing adjustment element driving the sealing element to adjust its position in the height direction, so that the open end of the sealing element extends into or detaches from the sealing fluid;

[0012] A sensing component includes a first sensor, a second sensor, and a detector. The first sensor and the second sensor are spaced apart along the height direction from the sealing element. The detector is located above the sealing liquid and is adapted to the first sensor and the second sensor, respectively.

[0013] A liquid level detection component for detecting the liquid level height of the sealing fluid; and

[0014] The control alarm component is electrically connected to the sealing adjustment component, the detection component, and the liquid level detection component, respectively.

[0015] According to one embodiment of the present invention, the drain pipe passes through the drain body along the height direction, and the sealing adjustment member is disposed at the upper end of the drain pipe and connected to the inner wall of the sealing member.

[0016] According to one embodiment of the present invention, the sealing adjustment member includes a driving part and a support rod. The driving part is disposed at the upper end of the drain pipe, one end of the support rod is connected to the driving end of the driving part, and the other end is connected to the inner wall of the sealing member.

[0017] According to one embodiment of the present invention, the detector and the liquid level detection assembly are sequentially spaced from top to bottom along the height direction on the drain body.

[0018] According to one embodiment of the present invention, the control and warning assembly includes a control component and a display component, wherein the control component is electrically connected to the display component, the sealing adjustment component, the detection component, and the liquid level detection assembly.

[0019] According to one embodiment of the present invention, it further includes a filter assembly disposed at the opening of the drain body.

[0020] According to one embodiment of the present invention, it further includes a cover plate assembly, the cover plate assembly including a cover plate member and a panel member, the cover plate member having a clearance opening, the cover plate member covering the drain body, the panel member being detachably connected to the clearance opening of the cover plate member and facing the opening of the drain body, and a drain outlet being formed on the panel member.

[0021] According to one embodiment of the present invention, the sealing liquid includes an ionic liquid sealing layer and a water seal layer, wherein the ionic liquid sealing layer is submerged at the bottom of the drain body and the water seal layer is located on the ionic liquid sealing layer.

[0022] According to one embodiment of the present invention, the liquid level of the ionic liquid sealing layer is greater than or equal to 4 cm.

[0023] According to one embodiment of the present invention, the ionic liquid sealing layer is composed of one or both of 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide salt or 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide salt.

[0024] Compared with existing technologies, this technology intelligently achieves the blocking of indoor sewage discharge and odors and harmful gases in sewer pipes through the cooperation of sealing components, sensing components, and control alarm components. Furthermore, the liquid level detection component detects the level of the sealing fluid. When the sealing fluid level is insufficient, that is, when the first sensing element and the detection element establish a wireless sensing connection, the opening end of the sealing element can no longer extend into the sealing fluid to form a barrier. At this time, the liquid level detection component will send a sensing signal to the control alarm component to warn of insufficient sealing fluid, reminding the user to add sealing fluid, thereby ensuring sufficient sealing fluid and ensuring the blocking of odors and harmful gases in sewer pipes.

[0033] Example 1

[0034] Reference Figures 1 to 3 , Figure 1 This is a schematic diagram of the intelligent adjustable residential floor drain device in the embodiment. Figure 2 This is a schematic diagram illustrating how the sealing element and sealing fluid work together to block harmful gases in the sewer pipe, as shown in the embodiment. Figure 3 This is a schematic diagram of the flow path of sewage within the intelligent adjustable residential floor drain device in this embodiment. The intelligent adjustable residential floor drain device in this embodiment includes a floor drain body 1, a drain pipe 2, a sealing assembly 3, a sensing assembly 4, a liquid level detection assembly 5, and a control and alarm assembly 6. The floor drain body 1 has a receiving space containing a sealing liquid 100. The drain pipe 2 is connected to the receiving space and leaks into the sealing liquid 100. The sealing assembly 3 includes a sealing element 31 and a sealing adjustment element 32. The sealing adjustment element 32 is connected to the sealing element 31. The sealing element 31 is located within the receiving space and covers the drain pipe 2. The sealing adjustment element 32 drives the sealing element 31 to adjust its position in the height direction, causing the open end of the sealing element 31 to extend into or detach from the sealing liquid 100. The sensing component 4 includes a first sensor 41, a second sensor 42, and a detector 43. The first sensor 41 and the second sensor 42 are spaced apart along the height direction on the sealing component 31. The detector 43 is located above the sealing liquid 100 and is adapted to both the first sensor 41 and the second sensor 42. The liquid level detection component 5 is used to detect the liquid level of the sealing liquid 100. The control and alarm component 6 is electrically connected to the sealing adjustment component 32, the detector 43, and the liquid level detection component 5.

[0035] When there is no sewage discharge from outside, the open end of the seal 31 extends into the sealing liquid 100. The barrier structure formed by the cooperation of the seal 31 and the sealing liquid 100 prevents odors and harmful gases from the drain pipe 2 from entering the indoor space. At this time, both the first sensor 41 and the second sensor 42 are outside the sealing liquid 100. The first sensor 41 is located above the second sensor 42, and the detector 43 is positioned opposite the first sensor 41 located above it. The detector 43 can sense the signal of the first sensor 41, and a wireless inductive connection is formed between the two. In this embodiment, the open end of the seal 31 extends into the sealing liquid 100 at a distance of more than 2 cm from the liquid surface to ensure the barrier effect.

[0036] When external sewage is discharged into the receiving space of the drain body 1, the sewage level in the receiving space gradually rises, first submerging the second sensor 42, and then the first sensor 41. When the sewage blocks the signal sensing between the detector 43 and the first sensor 41, the detector 43 sends a corresponding signal to control the alarm component 6. The alarm component 6 controls the sealing adjustment component 32 to raise the sealing component 31 until the second sensor 42 and the detector 43 are aligned. At this time, the sewage can flow into the drain pipe 2 through the opening end of the sealing component 31. The sealing liquid 100 has a density greater than water and has hydrophobic properties that are insoluble in water. Therefore, the sealing liquid 100 will still sink to the bottom of the drain body 1 and will not flow with the sewage. In this embodiment, when sewage is discharged, the sealing adjustment component 32 will raise the sealing component 31 by 4 cm.

[0037] When the detector 43 senses the signal from the second sensor 42 and a wireless connection is established between them, it indicates that there is no sewage obstructing the connection between the detector 43 and the second sensor 42. This means that sewage is no longer flowing into the drain body 1 and the sewage discharge is complete. At this time, the second sensor 42 will send a corresponding signal to the control alarm component 6. The control alarm component 6 will control the sealing adjustment component 32 to lower the sealing component 31 by 4cm until the first sensor 41 and the detector 43 establish a wireless connection. At this time, the open end of the sealing component 31 will also re-enter the sealing liquid 100, forming a new barrier.

[0038] Thus, the intelligent adjustable residential floor drain device in this embodiment intelligently achieves the blocking of indoor sewage discharge and odors and harmful gases in the drain pipe 2 through the cooperation of the sealing component 3, the sensing component 4, and the control and alarm component 6. Furthermore, the liquid level detection component 5 detects the liquid level of the sealing fluid 100. When the liquid level of the sealing fluid 100 is insufficient, that is, when the first sensing element 41 and the detection element 43 establish a wireless sensing connection, the opening end of the sealing element 31 can no longer extend into the sealing fluid 100 to form a barrier. At this time, the liquid level detection component 5 will send a sensing signal to the control and alarm component 6 to warn of insufficient sealing fluid 100, reminding the user to add sealing fluid 100, thereby ensuring sufficient sealing fluid 100 and ensuring the blocking of odors and harmful gases in the drain pipe 2.

[0039] Rereference Figures 1 to 3 Furthermore, the drain body 1 has a groove structure with a funnel-shaped opening to allow sewage or added sealing fluid 100 to flow smoothly into the interior of the drain body 1 along the slope of the opening. In this embodiment, the accommodating space is the groove-shaped internal space of the drain body 1.

[0040] Preferably, the drain pipe 2 passes through the drain body 1 along the vertical direction, and the sealing adjustment component 32 is located at the upper end of the drain pipe 2 and connected to the inner wall of the sealing component 31. Thus, the drain pipe 2 can support the sealing adjustment component 32. Specifically, the drain pipe 2 is a drain pipe pre-embedded along the vertical direction in the home. Its lower end is connected to the central drain pipe, and its upper end passes through the bottom wall of the groove of the drain body 1 along the vertical direction, extending a certain distance towards the opening of the drain body 1 and communicating with the receiving space. When there is no sewage discharge, this extension distance allows the opening of the drain pipe 2 to be positioned between the first sensor 41 and the second sensor 42. In this embodiment, this extension distance can be 6-10cm. The vertical direction in this embodiment refers to the vertical direction of the pre-embedded drain pipe during home renovation.

[0041] Preferably, the sealing element 31 is bell-shaped, and in this embodiment, the cross-section of the sealing element 31 is U-shaped. The sealing element 31 is located in the receiving space, with its open end facing the bottom wall of the groove facing the drain body 1, and there is a gap between it and the bottom wall of the groove of the drain body 1. There is a gap between the outer wall of the sealing element 31 and the inner wall of the groove of the drain body 1. The sealing element 31 is covered on the upper end of the drain pipe 2, and there is a gap between it and the drain pipe 2.

[0042] Preferably, the sealing adjustment component 32 includes a driving part 321 and a support rod 322. The driving part 321 is located at the upper end of the drain pipe 2. One end of the support rod 322 is connected to the driving end of the driving part 321, and the other end is connected to the inner wall of the sealing component 31. Through the cooperation of the driving part 321 and the support rod 322, the position of the sealing component 31 in the height direction can be adjusted so that the open end of the sealing component 31 can be submerged below the surface of the sealing liquid 100, or leave the sealing liquid 100 and make contact with the seal. The drive unit 321 is a hydraulic device, and the support rod 322 is a hydraulic strut. In this embodiment, there are two drive units 321 and two support rods 322. The two drive units 321 are respectively arranged on opposite sides of the drain pipe 2. The support rods 322 are parallel to the drain pipe 2. One end of the support rod 322 is connected to the drive unit 321, and the other end is connected to the bottom wall of the seal 31. The two support rods 322 support the seal 31 from two points, so that the drive unit 321 can stably drive the seal 31, allowing the seal 31 to rise or fall smoothly. In specific applications, the sealing adjustment component 32 will be waterproofed.

[0043] Preferably, the first sensor 41 and the second sensor 42 are respectively disposed on the outer wall of the sealing member 31 and arranged at intervals along the height direction. The interval between the first sensor 41 and the second sensor 42 is 3-6 cm. Preferably, in this embodiment, the interval between the first sensor 41 and the second sensor 42 is 4 cm. When discharging sewage, the sealing adjustment member 32 causes the sealing member 31 to rise or fall by a height equal to the interval between the first sensor 41 and the second sensor 42.

[0044] Preferably, the detector 43 and the liquid level detection component 5 are sequentially and spaced apart from top to bottom along the height direction on the side wall of the drain body 1. The detector 43 is adapted to the first sensor 41 and the second sensor 42. In specific applications, existing through-beam sensors can be used, and there is no limitation here. When there is sewage obstruction between the detector 43 and the first sensor 41, or between the detector 43 and the second sensor 42, or when there is no sewage obstruction, the detector 43 will generate different level signal changes. This change is transmitted to the control alarm component 6, providing information for the control alarm component 6 to control the sealing adjustment component 32. In this embodiment, the liquid level detection component 5 can be an existing water level sensor, and there is no limitation here. In specific applications, when the liquid level of the sealing liquid 100 drops to a preset height, the liquid level detection component 5 will send a signal to the control alarm component 6, and the control alarm component 6 will issue an alarm based on the signal. For example, if the liquid level of the sealing fluid 100 is 2cm, when the liquid level detection component 5 detects that the liquid level of the sealing fluid 100 has dropped to 1.5cm, it sends a signal to the control alarm component 6, and the control alarm component 6 issues an alarm message.

[0045] Preferably, the control and alarm component 6 includes a control element (not shown in the figure) and an alarm display element (not shown in the figure). The control element is electrically connected to the alarm display element, the sealing adjustment element 32, the detector element 43, and the liquid level detection component 5. The detector element 43 cooperates with the first sensor element 41 and the second sensor element 42 to detect and collect signals, which are then transmitted to the control element. The control element drives and controls the sealing adjustment element 32 according to the corresponding signals, causing the sealing element 31 to rise and fall, thus intelligently realizing the drainage and sealing functions of the floor drain device. Preferably, the liquid level detection component 5 detects the liquid level signal of the sealing fluid 100 and transmits it to the control component. The control component then controls the display and alarm component to display a warning message or issue an audible warning. For example, the warning message can be a visual numerical display indicating that the sealing fluid level is insufficient, a warning color display, or an audible warning. In this embodiment, when the liquid level detection component 5 detects that the liquid level of the sealing fluid 100 is below 1.5cm, the control component controls the display and alarm component to directly display a red color indicating that the sealing fluid level is below 15mm, thereby providing a warning message that can attract the user's attention so that the user can replenish the sealing fluid 100. When the level of the replenished sealing fluid is above 1.5cm, the warning message disappears. In this embodiment, the control component can be an existing controller, which has the functions of data acquisition, calculation, analysis, and command issuance. The alarm display component can be a display or a speaker, or a combination of both. In specific applications, a microcontroller with an integrated MCU control chip, display, and speaker can be used. The control alarm component 6 is waterproofed as a whole and is electrically connected to the detector 43, the liquid level detection component 5, and the sealing adjustment component 32 through waterproof lines. The control alarm component 6 can be embedded in the ground or wall, or embedded in the cover plate surface of the floor drain device. No limitation is made here.

[0046] Reproduce from drawings 1 to 12 Figure 3 Furthermore, the intelligent adjustable residential floor drain device in this embodiment also includes a filter assembly 7, which is located at the opening of the floor drain body 1. Wastewater flows into the floor drain body 1 after passing through the filter assembly 7. The filter assembly 7 filters out large particles, hair, and other insoluble solid deposits from the wastewater, preventing these deposits from entering the floor drain body 1 and the sealing fluid 100, thus avoiding affecting the sealing effect and clogging the drain pipe 2. In this embodiment, the filter assembly 7 can be a filter screen, which can be embedded in the opening of the floor drain body 1 and detached from the opening to remove large particles and hair accumulated on the filter screen.

[0047] Please refer to the following: Figure 4 , Figure 4This is a schematic diagram of the cover assembly in the embodiment. Furthermore, the intelligent adjustable residential floor drain device also includes a cover assembly 8, which includes a cover plate 81 and a panel 82. The cover plate 81 has a clearance opening and covers the floor drain body 1. The panel 82 is detachably connected to the clearance opening of the cover plate 81 and faces the opening of the floor drain body 1. A drain outlet 821 is formed on the panel 82. The cover plate 81 is plate-shaped, embedded in the surface of the base plate, and covers the floor drain body 1. Its clearance opening faces the opening of the floor drain body 1, and the two are compatible. In this embodiment, the filter assembly 7 is detachable and located at the opening of the floor drain body 1, facing the clearance opening of the cover plate 81. The operator can pick up the filter assembly 7 through the clearance opening. The panel 82 is also plate-shaped, its shape matching the clearance opening. The panel 82 is detachably connected to the clearance opening of the cover plate 81 via a snap-fit ​​structure 822, and faces the filter assembly 7. The snap-fit ​​structure 822 can be any existing snap-fit ​​structure, and is not limited here. Making the panel 82 detachable not only protects the filter assembly 7 but also facilitates cleaning after disassembly. Preferably, the drain outlets 821 on the panel 82 are annular, and there are multiple annular drain outlets arranged sequentially from the inside out, with a gap between adjacent annular drain outlets, so that sewage can flow smoothly into the drain body 1. Preferably, the panel 82 has anti-slip textures 823. The anti-slip textures 823 increase the friction on the panel 82, preventing slippage and safety hazards. In this embodiment, the anti-slip textures 823 are cross-shaped anti-slip patterns on the panel 82.

[0048] Example 2

[0049] Please refer to the following: Figure 5 , Figure 5 This is a schematic diagram of the sealing fluid layers in this embodiment. The intelligent adjustable residential floor drain device in this embodiment differs from that in Embodiment 1 in that the sealing fluid 100 includes an ionic liquid sealing layer 101 and a water seal layer 102. The ionic liquid sealing layer 101 is submerged at the bottom of the floor drain body 1, and the water seal layer 102 is located on top of the ionic liquid sealing layer. Preferably, the liquid level of the ionic liquid sealing layer 101 is greater than or equal to 4 cm.

[0050] In this embodiment, the ionic liquid sealing layer 101 is mainly composed of ionic liquid. Using ionic liquid as the main component of the sealing liquid 100, the extremely low vapor pressure, high density, and hydrophobic properties of the ionic liquid are utilized to achieve both drainage and a long-lasting sealing effect. In this embodiment, the density of the ionic liquid is 1.34 g / cm³. 3The liquid level of the ionic liquid sealing layer 101 is 4 cm high, and the thickness of the water seal layer 102 is 1-2 cm. This makes the total height of the sealing liquid 100 reach more than 5 cm. When there is no sewage discharge, the open end of the sealing element 31 extends to a position more than 2 cm below the liquid level of the sealing liquid 100, that is, the open end of the sealing element 31 extends into the ionic liquid sealing layer 101, thereby achieving a good sealing effect. Even if the water in the water seal layer 102 dries up due to evaporation, the hydrophobic ionic liquid sealing layer, which is mainly composed of ionic liquid, will still have a good sealing effect. Moreover, due to the fact that the density of the ionic liquid sealing layer is greater than that of water and its hydrophobic properties, it always remains at the bottom of the drain body 1 and will not flow into the sewer pipe 2 with the sewage during sewage discharge. During cleaning, simply add a large amount of clean water through the drain outlet 821 of panel 82 into the drain body 1 to clean the ionic liquid sealing fluid, removing water-soluble impurities and purifying the sealing fluid 100. Furthermore, due to the green, non-toxic, and pollution-free characteristics of the ionic liquid, it poses no threat to human health and has excellent performance. If you want to replace the internal sealing fluid, there is no need to remove the drain device. Simply add a specific detergent and flush with plenty of water to drain the old sealing fluid, then add new sealing fluid. Preferably, the ionic liquid sealing layer is composed of one or both of 1-ethyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide salt or 1-butyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide salt.

[0051] In summary, the intelligent adjustable residential floor drain device in this embodiment is highly intelligent. It can automatically achieve sewage discharge and sealing without disordered management in daily life. It also isolates odors and harmful gases through the cooperation of sealing components and sealing liquid. Furthermore, the liquid level detection component monitors the sealing liquid level and promptly issues an alarm when the sealing liquid is insufficient to ensure sufficient sealing liquid. Moreover, since ionic liquid is used as the main component of the sealing liquid, the high density and hydrophobic properties of ionic liquid are utilized to achieve a long-lasting sealing effect while draining water.

[0052] The above description is merely an embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art.
