Description

Technical Field

[0001] This invention relates to the field of toilet technology, specifically to an embedded intelligent toilet seat with integrated heating and temperature control. Background Technology

[0002] Toilets are essential bathroom products in daily life, including toilet seat, toilet seat, toilet lid and water tank. Toilet seat is generally a hard plastic product that provides support for the body when using the toilet. In winter, there is a large temperature difference between the toilet seat and the skin, which makes the user feel cold and uncomfortable.

[0003] In existing technologies, toilet seat covers generally only provide soft support to users and cannot effectively raise the temperature of the toilet seat. A toilet seat with a low temperature can cause harm to the user's body and affect their health. Some toilet seat covers with heating functions use infrared sensors or voice modules to control the temperature of the toilet seat. However, since the toilet is located in the bathroom, when the bathroom space is small, the infrared sensor may be misactivated during the user's shower, causing the toilet seat to heat up even when it is not in use. Furthermore, toilet seat covers controlled by voice modules are inconvenient to use at night, as they may disturb the rest of others.

[0004] In addition, most toilet seat covers are designed for adult sizes, making them difficult for children to use. Although there are toilet seat covers specifically for children on the market, which are installed on top of adult toilet seat covers, the inconsistent sizes of toilet seat covers often result in poor fit between children and adults, causing them to loosen or wobble, leading to inconvenience and safety issues. Some parents then buy smaller portable toilets, which require additional cleaning, causing further inconvenience. Summary of the Invention

[0005] To address the shortcomings of the aforementioned technologies, this invention provides an embedded intelligent toilet seat with integrated heating and temperature control, thereby resolving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution:

[0007] An embedded smart toilet seat with integrated heating and temperature control includes: a first toilet seat, a second toilet seat, a first connecting seat, a heating mechanism, a pipe mechanism, and an ultrasonic sensor. The first toilet seat has an opening in the middle and includes an upper shell and a lower shell with a cavity between them. The heating mechanism is located on the inner wall of the upper shell. The pipe mechanism includes a first pipe and a second pipe. One end of the first pipe is fixedly connected to one end of a first connector, and the other end of the first connector is fixedly connected to one end of the second pipe. The other end of the second pipe is fixedly connected to one end of a second connector, and the other end of the second connector is fixedly connected to the other end of the first pipe. The second pipe is spirally arranged around the inner wall of the lower shell. A sensor ball is located inside the pipe mechanism.

[0008] Furthermore, the heating mechanism includes a heating element and a heating wire. The heating mechanism is symmetrically arranged about the axis of the toilet seat. The heating element is provided on the inner wall of the upper shell. The heating wire is provided on the side of the heating element away from the upper shell. The heat generated by the heating wire is conducted to the outer wall of the upper shell through the heating element. The heating wire is electrically connected to the temperature control switch, the detection head and the power supply in sequence.

[0009] Furthermore, the heating element is a graphene heating element or a polyimide heating element, the heating wire is a copper heating wire, the detection head is an NTC detection head, and the heating element is installed in the upper and lower housings by injection molding.

[0010] Furthermore, the rear end of the first toilet seat is provided with a first connecting rod, the other end of which is hinged to the front end of the first connecting seat; the rear end of the second toilet seat is provided with a second connecting rod, the other end of which is hinged to the top end of the first connecting seat.

[0011] Furthermore, a first strip-shaped hole is provided on one side of the first connector, and a first mating block is provided on the surface of the first connector on both sides of the first strip-shaped hole. The first mating block is respectively hinged to one end of the third connecting rod. The middle part of the third connecting rod is fixedly connected to one end of the fourth connecting rod. A first limiting block is provided at the other end of the fourth connecting rod. A first through hole is provided on one side of the second connector, and an ultrasonic sensor is provided on the inner wall of the lower housing outside the first through hole.

[0012] Furthermore, the inner wall of the lower housing near the opening is provided with a plurality of first fixing blocks, and the first fixing blocks are provided with second pipes.

[0013] Furthermore, a controller is provided on the inner wall of the lower housing outside one side of the ultrasonic sensor, and a power supply is provided on the inner wall of the lower housing outside one side of the controller. The power supply is electrically connected to the controller, and the controller is electrically connected to both the ultrasonic sensor and the detection head.

[0014] Furthermore, the second toilet seat has the same structure as the first toilet seat, but the area of ​​the second toilet seat is smaller than that of the first toilet seat.

[0015] The beneficial effects of this invention are as follows:

[0016] The toilet seat doesn't require an additional switch on its surface. The switching between heating, heat preservation, and heating deactivation occurs automatically within the toilet seat itself, changing with the user's actions of lifting or flattening it. This facilitates heating, promotes a seamless design, and provides excellent waterproofing. Furthermore, the heating mechanism is injection-molded into the upper and lower housings, effectively preventing heat loss. Additionally, the use of a first connecting seat to accommodate different sized toilet seats allows the toilet seat to meet the needs of both adults and children. Attached Figure Description

[0027] 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.

[0028] This invention provides, for example Figures 1 to 9 The smart toilet seat with embedded heating and temperature control, as shown, includes: a first toilet seat 1, a second toilet seat 2, a first connecting seat 3, a heating mechanism 4, a pipe mechanism 9, and an ultrasonic sensor 10. The first toilet seat 1 has an opening 5 in the middle. The first toilet seat 1 includes an upper shell 6 and a lower shell 7, with a cavity 8 between the upper shell 6 and the lower shell 7. The heating mechanism 4 is provided on the inner wall of the upper shell 6. The pipe mechanism 9 includes a first pipe 11 and a second pipe 12. One end of the first pipe 11 is fixedly connected to one end of a first connector 13, and the other end of the first connector 13 is fixedly connected to one end of the second pipe 12. The other end of the second pipe 12 is fixedly connected to one end of a second connector 14, and the other end of the second connector 14 is fixedly connected to the other end of the first pipe 11. The second pipe 12 is spirally arranged around the inner wall of the lower shell 7. A sensing ball is provided inside the pipe mechanism 9.

[0029] The toilet seat is hinged to a first toilet seat 1 and a second toilet seat 2 via a first connecting seat 3. The first toilet seat 1 is integrally formed by injection molding of an upper shell 6 and a lower shell 7. The first toilet seat 1 and the second toilet seat 2 are identical in structure and function except for the size of the toilet seat body. Therefore, the structure of the first toilet seat 1 will be explained in the following description. The structure and principle of the second toilet seat 2 are the same as those of the first toilet seat 1, so they will not be described again.

[0030] Meanwhile, the pipe mechanism 9 includes a first pipe 11 and a second pipe 12. The first pipe 11 is a rigid pipe to ensure it is not easily deformed during use, while the second pipe 12 is a flexible pipe to ensure it can spirally surround the inner wall of the lower housing 7. Both the first pipe 11 and the second pipe 12 are conventional pipes, which are relatively inexpensive. By using the pipe mechanism 9 with a certain length to control the heating temperature, the production cost of the toilet seat is effectively reduced compared to simply setting electronic components. The sensor ball is set inside the pipe mechanism 9. When the user flips the toilet seat during toilet use, the sensor ball... The ultrasonic sensor 10 will roll within the pipe mechanism 9. The ultrasonic sensor 10 senses the sensing ball through the first through-hole 23 of the second connector 14, thereby controlling the toilet seat to start heating, maintain temperature, and stop heating. Specifically, when the user needs to use the toilet, the toilet seat and the first toilet seat 1 are first flipped up together. At this time, the sensing ball leaves the second connector 14 and travels through the first pipe 11 to the first connector 13. After the ultrasonic sensor 10 senses the movement of the sensing ball, it sends a signal back to the controller 25, which then controls the heating wire 28 to heat and enter the heating state. After the toilet seat and the first toilet seat 1 are flipped up, the single... When the first toilet seat 1 is laid flat, the sensing ball enters the second pipe 12 through the first connector 13. Because the second pipe 12 is spirally arranged with a certain height difference, it can roll back to the second connector 14 along the second pipe 12. At this time, the ultrasonic sensor 10 senses the sensing ball again and feeds the signal back to the controller 25. The controller 25 then controls the heating degree of the heating wire 28 to make the first toilet seat 1 have a suitable and stable temperature and enter the heat preservation state. After use, the first toilet seat 1 is flipped up. At this time, the sensing ball leaves the second connector 14 again and returns to the first connector 14 through the first pipe 11. When the ultrasonic sensor 10 detects the sensor ball leaving the toilet seat again, it sends a signal to the controller 25, which then controls the heating wire 28 to stop heating and enter the off state. After the first toilet seat 1 is flipped up again, the toilet seat and the first toilet seat 1 are laid flat together. At this time, the sensor ball returns to the second connector 14 through the second pipe 12. The ultrasonic sensor 10 detects the sensor ball again, but it is in the off state. The ultrasonic sensor 10 sends a signal to the controller 25, but the controller 25 does not respond. Repeating this process can continuously realize the start heating, heat preservation and heating shutdown of the first toilet seat 1.

[0031] Furthermore, the switching between heating, heat preservation, and heating off states of the toilet seat is automatically completed by the user's action of flipping up or flattening the toilet seat, without the need for an additional switch on the surface of the toilet seat. This facilitates the integrated design of the toilet seat and also increases its waterproof performance. In addition, different lengths of the second pipe 12 can be set during production, thereby allowing the toilet seat to have different heating times.

[0032] In alternative implementations, such as Figure 2 As shown, the heating mechanism 4 includes a heating element 15 and a heating wire 28. The heating mechanism 4 is symmetrically arranged about the axis of the toilet seat. The heating element 15 is provided on the inner wall of the upper housing 6. The heating wire 28 is provided on the side of the heating element 15 away from the upper housing 6. The heat generated by the heating wire 28 is conducted to the outer wall of the upper housing 6 through the heating element 15. The heating wire 28 is electrically connected to the temperature control switch, the detection head 27 and the power supply 26 in sequence.

[0033] The upper shell 6 of the first toilet seat 1 is part of the cavity 8, which provides space for installing the required components. The inner wall of the upper shell 6 of the first toilet seat 1 is fixedly connected to the heating element 15 by adhesive. The heating element 15 is provided with a heating wire 28 on the side away from the inner wall of the upper shell 6. After the heating wire 28 is heated, it conducts the heat generated by itself to the heating element 15. The heating element 15 then conducts the obtained heat to the outer wall of the upper shell 6, thereby realizing the heating of the first toilet seat 1.

[0034] Meanwhile, the heating element and heating wire 28 are only installed on the inner wall of the upper shell 6, and not on the inner wall of the lower shell 7. This is beneficial for saving energy, because during the use of the toilet seat, the user only comes into contact with the outer wall of the upper shell 6. Therefore, the heating element 15 and heating wire 28 are only installed on the inner wall of the upper shell 6. This saves energy and reduces the cost of use while meeting the user's needs, and it is environmentally friendly.

[0035] In addition, the maximum heating temperature of the heating wire 28 is controlled by a temperature control switch to prevent the toilet seat from overheating and scalding the user. When the temperature of the heating wire 28 exceeds the maximum heating temperature, the power supply of the power supply 26 is cut off. The detection head 27 is fixedly installed on the heating element 15 and detects the temperature inside the toilet seat and feeds the temperature data back to the controller 25, thereby controlling the heating time or heating power.

[0036] In alternative implementations, such as Figure 2 As shown, the heating element 15 is a graphene heating element or a polyimide heating element, the heating wire 28 is a copper heating wire, the detection head 27 is an NTC detection head, and the heating element 15 is disposed in the upper housing 6 and the lower housing 7 by injection molding.

[0037] Among them, polyimide heating elements are thin, lightweight, and flexible, occupying little space, with a thickness generally less than 0.3mm; their shape and size can be customized as needed, making them suitable for manufacturing extremely small flexible electric heating film elements; they adopt a planar heating method, resulting in extremely high surface power density, reaching up to 3W / cm2, and featuring better heating uniformity and faster heating rate; polyimide heating elements can meet different heating power and temperature requirements in different areas, and the heating area can be evenly distributed on the designed surface as required; they have low thermal inertia, high temperature control accuracy, and fast speed, hence the use of polyimide heating elements as heating elements; while graphene heating elements have a thermal conversion rate of up to 98%, can generate heat through far-infrared radiation, and have high voltage resistance, making them also a good choice for heating elements.

[0038] In addition, the heating element 15 and heating wire 28 are installed in the upper shell 6 and lower shell 7 by injection molding, which effectively prevents the loss of heat from the toilet seat. Since the heating element 15 and heating wire 28 are installed inside the toilet seat, and the toilet seat is integrally molded by injection molding, it has good waterproof and drop-proof performance.

[0039] In alternative implementations, such as Figure 1 As shown, the rear end of the first toilet seat 1 is provided with a first connecting rod 16, and the other end of the first connecting rod 16 is hinged to the front end of the first connecting seat 3. The rear end of the second toilet seat 2 is provided with a second connecting rod 17, and the other end of the second connecting rod 17 is hinged to the top end of the first connecting seat 3.

[0040] The first toilet seat 1 and the second toilet seat 2 are respectively hinged to the first connecting seat 3. The hinged connection enables the first toilet seat 1 and the second toilet seat 2 to have the function of flipping. The two toilet seats are provided to give users multiple choices when they need to use toilet seats, which can better meet the needs of different users and has good versatility.

[0041] Furthermore, since the second connecting rod 17 of the second toilet seat 2 is hinged to the top of the first connecting seat 3, and the first connecting rod 16 of the first toilet seat 1 is hinged to the front end of the first connecting seat 3, the length of the second connecting rod 17 must be greater than the length of the first connecting rod 16, so that the second toilet seat 2 can be in the corresponding position when it is put down.

[0042] In alternative implementations, such as Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, a first strip hole 18 is provided on one side of the first connector 13, and a first mating block 19 is provided on the surface of the first connector 13 on both sides of the first strip hole 18. The first mating block 19 is hinged to one end of the third connecting rod 20. The middle part of the third connecting rod 20 is fixedly connected to one end of the fourth connecting rod 21. A first limiting block 22 is provided at the other end of the fourth connecting rod 21. A first through hole 23 is provided on one side of the second connector 14, and an ultrasonic sensor 10 is provided on the inner wall of the lower housing 7 outside the first through hole 23.

[0043] The first connector 13 has a first slotted hole 18, and a first pipe 11 is connected to one end of the first connector 13 near the first slotted hole 18. A first mating block 19 is located at one end of the first slotted hole 18 near the first pipe 11. A fourth connecting rod 21 is located in the middle of the third connecting rod 20 hinged to the first mating block 19. When the toilet seat is in a flat position, the sensing ball is at the second connector 14. The user then flips the toilet seat to the flipped-up position. During this flipping process, the sensing ball rolls from one end of the first pipe 11 near the second connector 14 to the other end of the first pipe 11 near the first connector 13. After reaching the first connector 13, the sensing ball first contacts the first limiting block 22. The sensing ball has an impact force during its rolling, which impacts the first limiting block 22. The first limiting block 22 causes the fourth connecting rod 21 to swing at a certain angle in the first slotted hole 18, thereby changing the position of the first limiting block 22. The sensing ball does not act as an obstruction, thus allowing it to enter the interior of the first connector 13. After entering the first connector 13, the sensing ball will contact the first limiting block 22 again. However, at this time, the first limiting block 22 cannot cause the fourth connecting rod 21 to swing at a certain angle in the first slot 18. This is because the first mating block 19 is located at the end of the first slot 18 near the first pipe 11, thereby positioning the fourth connecting rod 21 at the end of the first slot 18 near the first pipe 11 and abutting against the end face of the first slot 18 near the first pipe 11. The end face of the first slot 18 near the first pipe 11 has a limiting effect on the fourth connecting rod 21, thus allowing the fourth connecting rod 21 to swing only away from the first pipe 11 and not towards the first pipe 11. This prevents the sensing ball from falling back into the first pipe 11 after entering the first connector 13 from the first pipe 11.

[0044] Meanwhile, a first through hole 23 is provided on one side of the second connector 14, and an ultrasonic sensor 10 is provided outside the first through hole 23. When the toilet seat is in a flat state, the sensing ball is located at the second connector 14, and the ultrasonic sensor 10 can sense the sensing ball located at the second connector 14 through the first through hole 23.

[0045] In alternative implementations, such as Figure 4 and Figure 5 As shown, the inner wall of the lower housing 7 near the opening 5 is provided with a plurality of first fixing blocks 24, and the first fixing blocks 24 are provided with second pipes 12.

[0046] The second pipe 12 is a soft pipe. The first fixing block 24 is set on the inner wall of the lower shell 7 near the opening 5, which is conducive to fixing the second pipe 12 and further makes the second pipe 12 spirally distributed.

[0047] In alternative implementations, such as Figure 3 As shown, a controller 25 is provided on the inner wall of the lower housing 7 outside one side of the ultrasonic sensor 10, and a power supply 26 is provided on the inner wall of the lower housing 7 outside one side of the controller 25. The power supply 26 is electrically connected to the controller 25. The controller 25 is electrically connected to the ultrasonic sensor 10 and the detection head 27 respectively. The power supply 26 is electrically connected to the ultrasonic sensor 10 and the detection head 27 respectively.

[0048] The power supply 26 provides power, and the controller 25 controls the ultrasonic sensor 10, the detection head 27 and the heating wire 28 respectively, thereby controlling the normal operation of the toilet seat.

[0049] In alternative implementations, such as Figure 1 As shown, the second toilet seat 2 has the same structure as the first toilet seat 1, but the area of ​​the second toilet seat 2 is smaller than that of the first toilet seat 1.

[0050] Among them, the larger toilet seat 1 is an adult toilet seat, and the smaller toilet seat is a child toilet seat. By setting two different toilet seats through the first connecting seat 3, the needs of users can be better met.

[0051] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
