Description

Adjustable toilet Technical Field

[0001] This invention relates to the technical field of sanitary equipment, and in particular to an adjustable toilet bowl whose height can be adjusted according to the user's height. Through its integrated design that combines automatic sensing, safety limit and telescopic drainage structure, it can improve the convenience and hygiene quality of use for people of different heights, and can be applied in public places. Prior Technology

[0002] Note that most existing urinals in public places are wall-mounted structures with a fixed height. Their installation position is set according to the average adult height during construction and cannot be adjusted after completion. Although this type of design is simple in structure and low in cost, in actual use, due to significant differences in the height of different users, including young children, shorter people, the elderly, or people with mobility impairments, the urinal height often does not match, causing inconvenience. They may even have to tiptoe, lean forward, or rely on others to complete the toileting process. This not only affects their autonomy and dignity but also easily causes urine to splash, reducing the cleanliness of the public environment.

[0003] To cater to the needs of people of different heights, some public places have installed commode combinations of different heights or provided additional footrests as an aid. However, these methods are still static configurations and cannot be adjusted in real time according to the actual height of individual users, which also increases the burden of space configuration and maintenance management. Footrests may also pose safety concerns in wet and slippery environments and may not truly improve the overall quality of use.

[0004] In other words, existing toilet facilities mostly focus on fixed structural configurations or simple size distinctions, which are passive height-responsive designs. They are not yet able to dynamically adjust according to user conditions in real time, nor do they effectively integrate a collaborative control mechanism that combines sensor judgment and mechanical actuation. Therefore, it is difficult to simultaneously meet the needs of ease of use, public health quality, and the flexible needs of different groups.

[0005] In view of the aforementioned shortcomings and needs, the creator believed that further improvements were necessary. Therefore, based on years of experience in related technologies and product design and manufacturing, the creator researched and created solutions to address the above-mentioned deficiencies. Through continuous research and trial production, the creator finally successfully developed an adjustable toilet to overcome the inconvenience and problems caused by the existing structure. Summary of the Invention

[0006] Therefore, the main purpose of this invention is to provide an adjustable toilet that can automatically detect the user's height information when the user approaches and drive the toilet body to adjust to an appropriate height in the vertical direction, so that users of different heights can complete the toilet action without the need for a foot or additional auxiliary devices, thereby improving the convenience and autonomy of use.

[0007] Furthermore, another major objective of this invention is to provide an adjustable toilet bowl that can maintain the tightness and stability of the drainage system during the raising and lowering of the toilet bowl body, avoiding leakage or loosening problems caused by changes in height, thereby ensuring the reliability of equipment operation and the hygiene quality of the public environment.

[0008] Furthermore, another major objective of this invention is to provide an adjustable toilet that automatically stops operating when it reaches a preset position and returns to the preset initial position after the user leaves. This takes into account the safety of the equipment, the convenience of subsequent cleaning, and the readiness for the next use, thereby improving the overall management efficiency and safety protection of public health facilities.

[0009] Based on this, the present invention mainly achieves the aforementioned purpose and effect through the following technical means, including: a commode body; a lifting transmission module disposed on the rear side of the commode body and used to drive the commode body to move vertically; and a control module electrically connected to the lifting transmission module, which includes a microcontroller and at least one height sensor; wherein, the control module uses the height sensors to detect the relative distance or height information between the user and the commode body, and controls the lifting transmission module to operate according to the detection results, so as to adjust the height position of the commode body, so that the commode body can be adjusted to accommodate different user heights.

[0010] Therefore, this adjustable toilet utilizes the coordinated operation of the height sensor and microcontroller in the control module to automatically detect the user's height or relative height, and in real time control the lifting transmission module to drive the toilet body to make corresponding height adjustments. This allows users of different heights to use the toilet body at an appropriate height, thereby improving ease of use and autonomy, and reducing urine splashing caused by height discomfort. This improves the cleanliness of the public health environment, greatly enhances its practicality, and further realizes its economic benefits.

[0011] Furthermore, this invention also utilizes the following technical means to further achieve the aforementioned objectives and effects, such as: preferably, the lifting transmission module includes at least one guide post and a sliding seat disposed on the toilet body, so that the toilet body can smoothly slide up and down along the direction of the guide post.

[0012] Preferably, the lifting transmission module includes a lifting drive mechanism, which includes a lifting motor, a lifting screw driven by the lifting motor, and a nut seat disposed on the toilet body and screwed into the lifting screw, so as to drive the toilet body to move up and down by the forward or reverse rotation of the lifting motor.

[0013] Preferably, the height sensor is an infrared sensor, a distance sensor, or other sensing element used to detect the distance to a human body.

[0014] Preferably, the microcontroller of the control module is electrically connected to at least one travel limit switch, which is set at the upper or lower limit position of the lifting stroke of the toilet body, so as to limit the operation of the lifting transmission module when the toilet body moves to the limit position.

[0015] Preferably, the microcontroller of the control module is electrically connected to a manual adjustment switch, which allows the user to manually control the operation of the lifting transmission module to finely adjust the height of the commode body.

[0016] Preferably, the bottom end of the toilet body is provided with a drain connector and connected to a drain pipe, and the drain pipe is a telescopic or flexible pipe to accommodate the length change of the toilet body when it is raised and lowered.

[0017] Preferably, the toilet body is provided with a flushing outlet and connected to a water inlet pipe. The water inlet pipe is connected to a flushing controller and can be a telescopic or flexible pipe structure to accommodate the positional changes of the toilet body when it is raised or lowered.

[0024] In the accompanying drawings illustrating specific embodiments and components of this invention, all references to front and back, left and right, top and bottom, upper and lower, and horizontal and vertical are for convenience of description only and are not intended to limit the invention or restrict its components to any position or spatial orientation. Dimensions specified in the drawings and specification may be varied according to the design and requirements of this invention without departing from the scope of the claims.

[0025] Please refer to Figures 1 to 3. This invention is an adjustable toilet bowl, whose overall structure mainly includes a toilet bowl body (10), a lifting transmission module (20) located on the rear side or opposite position of the toilet bowl body (10), and a control module (30) electrically connected to the lifting transmission module (20). The control module (30) can detect the user's height information and output a corresponding drive signal to the lifting transmission module (20), so that it drives the toilet bowl body (10) to adjust its vertical displacement, thereby positioning the toilet bowl body (10) at an appropriate height that matches the user's height, thereby improving the convenience, stability, and autonomous use of the toilet.

[0026] The toilet body (10) is a semi-hung toilet structure. Its bottom interior has a drain connector (11) connected to the inner cavity of the toilet. This drain connector (11) is connected to a drain pipe (12) for draining wastewater, guiding the liquid in the toilet to the drainage system. The drain pipe (12) can be telescopic or flexible to accommodate height changes during the raising and lowering of the toilet body (10) and maintain the sealing and drainage function of the drainage connection. A flushing outlet (13) is located at the top interior of the toilet body (10) and communicates with its inner cavity, guiding clean water to the inner wall of the toilet for rinsing. The flushing outlet (13) is connected to a water inlet pipe (14), which is further connected to a flush controller (15) mounted on the wall to activate the flushing mechanism when a user is detected approaching. The water inlet conduit (14) can also adopt a telescopic or flexible conduit structure, so that its length can be adjusted by the lifting and lowering movement of the main body (10) to avoid the occurrence of pipe pulling or connection loosening.

[0027] The lifting transmission module (20) is used to enable the toilet body (10) to lift. It has a sliding seat (21) on the back or side edges of the toilet body (10). In this invention, a preferred embodiment has a sliding seat (21) on the side edges of the back of the toilet body (10). Two guide posts (22) are erected on the rear side of the toilet body (10) respectively, corresponding to the sliding seats (21), allowing the toilet body (10) to slide smoothly up and down relative to the guide posts (22). A lifting drive mechanism (25) is provided between the back of the toilet body (10) and the wall to actuate the toilet body (10). The lifting drive mechanism (25) of this invention can be a telescopic cylinder structure or a motor structure. The lifting drive mechanism (25) of this invention is based on a motor structure as the main embodiment. It includes a lifting motor (26), a lifting screw (27) rotated by the lifting motor (26), and a nut seat (28) provided on the back of the toilet body (10) and screwed opposite to the lifting screw (27). When the lifting motor (26) moves the lifting screw (27) in the forward and reverse directions, the nut seat (28) is fixed on the toilet body (10), so that the toilet body (10) can be moved up and down relative to each other. In addition, the lifting transmission module (20) is a structure used to make the toilet body (10) produce vertical lifting displacement. At least one sliding seat (21) is provided on the back of the toilet body (10) or on its two side edges. The preferred embodiment of this invention is to provide at least one sliding seat (21) on each of the two side edges of the back of the toilet body (10). Two guide posts (22) are provided on the rear side of the toilet body (10). These guide posts (22) slide and cooperate with the sliding seats (21) respectively, so that the toilet body (10) can move smoothly up and down along the direction of the guide posts (22) to provide lifting guidance and structural support functions. A lifting drive mechanism (25) is provided between the back of the toilet body (10) and the wall to drive the toilet body (10) to produce lifting displacement. The lifting drive mechanism (25) can be a telescopic cylinder structure or a motor drive structure, and this invention uses the motor drive method as the main embodiment. The lifting drive mechanism (25) mainly includes a lifting motor (26), a lifting screw (27) driven by the lifting motor (26) to rotate, and a nut seat (28) disposed on the back of the toilet body (10) and screwed with the lifting screw (27). When the lifting motor (26) drives the lifting screw (27) to rotate forward or backward, the nut seat (28) is fixedly disposed on the toilet body (10), so that the toilet body (10) can generate a corresponding upward or downward displacement along the direction of the guide post (22) to realize the function of adjusting the height of the toilet.

[0028] Furthermore, the control module (30) is electrically connected to the lifting transmission module (20) and can selectively be electrically connected to the flush controller (15). The control module (30) mainly includes a microcontroller (31) and at least one height sensor (32). The microcontroller (31) is used to receive and process the sensing signals and control the operation state of the lifting transmission module (20) according to the determination result, so as to drive the toilet body (10) to adjust its height. The height sensor (32) can be set on the ceiling, above the toilet body (10) or other positions where the user's height can be detected, to detect the distance information between the user and the device, and to calculate the user's height or relative height, so as to provide the microcontroller (31) with a basis for height determination. The height sensor (32) can be an infrared sensing element, a distance sensing element, or other sensing device suitable for human body distance detection; furthermore, the microcontroller (31) is electrically connected to at least one travel limit switch (35), which is set at the upper and lower limit positions of the lifting stroke of the commode body (10) to provide a travel limit signal when the commode body (10) moves to the limit position, so as to prevent the lifting motor (26) of the lifting transmission module (20) from running continuously and causing damage to the mechanism. In addition, the microcontroller (31) is also electrically connected to a manual adjustment switch (36) so that the user can manually control the operation of the lifting transmission module (20) when needed to fine adjust the height position of the commode body (10).

[0029] This allows for the creation of an adjustable toilet structure that can be height-adjusted according to the user's height, enabling the toilet body to be raised and lowered accordingly to different users' height conditions.

[0030] Please refer to Figures 1-3 and Figures 4 and 5. The operation process of the adjustable toilet in this invention is as follows when in actual use. First, after the system is powered on, the microcontroller (31) of the control module (30) enters the standby monitoring state, and the height sensor (32) set on the toilet body (10) continuously detects the ambient distance to detect whether a user is approaching the device.

[0031] When the height sensor (32) detects that a user has entered its sensing range, the height sensor (32) transmits the distance signal to the microcontroller (31). The microcontroller (31) performs calculations and judgments based on the received distance information to estimate the user's height or relative height position. The microcontroller (31) then determines whether the commode body (10) needs to be adjusted in height based on the preset height parameters.

[0032] When the determination result shows that the user's height is lower than the preset standard height, the microcontroller (31) outputs a control signal to the lifting transmission module (20), causing its lifting motor (26) to drive the lifting screw (27) to rotate. Through the engagement relationship between the nut seat (28) and the lifting screw (27), the commode body (10) is driven to move downward along the guide post (22) to a lower usage height. Conversely, if the user's height is determined to be close to or higher than the preset standard, the commode body (10) can maintain its original height or only make slight adjustments to meet the user's comfortable usage position. In addition, if the user needs to make a slight height adjustment during operation, the lifting transmission module (20) can be directly controlled through the manual adjustment switch (36) to make a small adjustment to the height of the commode body (10) to meet individual usage needs.

[0033] During the lifting process, the toilet body (10) maintains the stability of lifting through the sliding cooperation between the sliding seat (21) and the guide column (22). When the toilet body (10) moves to the predetermined height position or triggers the travel limit switch (35), the microcontroller (31) stops the operation of the lifting motor (26) to avoid excessive lifting and causing damage to the mechanism.

[0034] When the user leaves, if the height sensor (32) does not detect a human signal within a preset time (e.g., a few seconds to tens of seconds), the microcontroller (31) determines that the device has entered the reset procedure and controls the lifting motor (26) to run in reverse so that the toilet body (10) returns to the initial preset position (e.g., the higher standby position) to facilitate subsequent user operation and make the device easier to clean and manage.

[0035] Through the above control process, the adjustable toilet can automatically determine the user's height and adjust the height of the toilet body (10) through the non-contact detection mechanism of the height sensor (32), so that the device can adapt to the usage needs of different height groups. At the same time, with the structural design of the retractable drain pipe (12) and water inlet pipe (14), the drainage sealing and water supply functions during the lifting process are ensured. The travel limit switch (35) provides a safety protection mechanism, thereby improving the ease of use, hygiene quality and overall safety of public health facilities.

[0036] As can be seen from the above structure and control process, the adjustable toilet of this invention automatically detects the user's height or relative height through the coordinated operation of the height sensor (32) and the microcontroller (31), and controls the lifting transmission module (20) to drive the toilet body (10) to make corresponding lifting and lowering adjustments, so that users of different heights can use the toilet body (10) at an appropriate height position, thereby improving the convenience and autonomy of use, and reducing the problem of urine splashing caused by height discomfort, so as to improve the cleanliness of the public health environment.

[0037] Meanwhile, this invention provides drainage conduits (12) and water inlet conduits (14) at the drain and water supply ends of the toilet body (10), respectively, which can be adjusted for height changes. These conduits can be telescopic or flexible, ensuring stable pipe connections and sealing during the raising and lowering of the toilet body (10), thus preventing drainage leakage or water supply interruption and ensuring the reliability and safety of the equipment operation. In this way, this invention not only enhances the intelligence and flexibility of sanitary equipment, but also takes into account safety protection and equipment durability, thereby improving the overall quality of use of public health facilities.

[0038] Therefore, it can be understood that this creation is an excellent invention. In addition to effectively solving the problems faced by the previous inventors, it also greatly improves the efficacy. Furthermore, no identical or similar products have been created or publicly used in the same technical field. Since it also has the effect of improving efficacy, this creation meets the requirements of "novelty" and "inventiveness" for a utility model patent, and a utility model patent application is filed in accordance with the law.
