Description

Technical Field

[0001] The utility model relates to the technical field of toilets, and in particular to a pressure-sensing toilet seat and an intelligent toilet. Background Art

[0002] In existing smart toilet designs, whether there is a human body sitting on the seat is often identified by a capacitive sensor, and the sensing area is usually set at a specific position inside the seat, such as the front left side of the seat. Only when the user's body parts cover this preset sensing area can the smart toilet effectively identify and determine that the user is seated, and then activate a series of related functions such as flushing and heating. For adult users, the thigh area in a normal sitting position can usually completely cover the sensing area, ensuring smooth sensing and enabling of various functions. However, for child users, due to their small size, they may not be able to ensure that their bodies fully touch the sensing area when using it, resulting in the smart toilet being unable to accurately identify even if they sit down, and thus being unable to use related functions normally.

[0003] Therefore, the design that relies solely on capacitive sensing is not fully suitable for users of all ages, which to some extent reduces the consumer experience and puts forward new improvement requirements. To this end, the key challenge that the industry needs to solve is to develop a more universal and sensitive seating detection solution to eliminate this shortcoming in the user experience. Summary of the invention

[0004] The utility model provides a pressure-sensing toilet seat and an intelligent toilet, which overcome the deficiencies of the prior art described in the background technology.

[0005] The technical solution of the utility model is: a pressure-sensing toilet seat, comprising an upper cover, a lower cover, a foot pad and a pressure sensor, the lower cover having a cavity protruding upward, the cavity being formed by a top wall and a side wall, the foot pad being fixedly installed in the cavity, characterized in that: the pressure sensor is fixed on the outer surface of the top wall of the cavity, a conductive column is protruding downward on the inner surface of the top wall of the cavity, the conductive column presses against the foot pad, so that the pressure on the foot pad is transmitted to the top wall of the cavity through the conductive column and then further transmitted to the pressure sensor.

[0006] Preferably, the pressure sensor comprises a shell having a contact surface opposite to the outer surface of the top wall of the cavity.

[0007] Preferably, the pressure sensor has an optimal sensing conduction portion, and the conduction column is arranged directly below the optimal sensing conduction portion.

[0008] Preferably, a convex rib protruding toward the top wall of the cavity is provided on the contact surface of the shell corresponding to the conductive column.

[0009] Preferably, the shell is an axisymmetric structure, and the major axis of the convex rib is in the same vertical direction as the axis of the shell.

[0010] Preferably, the optimal induction conduction portion is located at the center of the shell, and the center of the shell and the center of the outer surface of the top wall of the cavity are in the same vertical direction.

[0011] Preferably, the pressure sensor is placed vertically and crosswise with the cavity.

[0012] Preferably, a fixing column is provided outside the cavity, and the pressure sensor is provided with a fixing hole corresponding to the fixing column. The pressure sensor is inserted into the fixing column through the fixing hole and is fixed to the lower cover by screws.

[0013] Preferably, the foot pad is arranged at the front end of the lower cover.

[0014] Preferably, the pressure sensor determines that the human body has taken a seat by calculating whether the amount of pressure deformation reaches a certain threshold.

[0015] The present application further provides a smart toilet, comprising a toilet body and the above-mentioned pressure-sensing toilet seat, wherein the toilet seat is rotatably attached to the toilet body.

[0016] Compared with the background technology, the technical solution of the present application can achieve the following beneficial effects:

[0017] 1. The use of pressure sensors no longer limits seat detection to a specific area. Even for children, as long as they reach a certain weight threshold, they can achieve all-round seat sensing. This method greatly optimizes the user experience, especially for children, significantly improving the convenience and comfort of use.

[0018] 2. The special setting of the conductive column helps to transmit pressure information more accurately, thereby greatly improving the detection sensitivity and triggering the seating sensing quickly and accurately.

[0019] 3. The optimal sensing and transmission part of the pressure sensor has been structurally optimized to more sensitively capture minute pressure changes, thus achieving more accurate seating perception.

[0020] 4. By adding a convex rib structure to the shell, the pressure sensing error that may be caused by differences in manufacturing precision is effectively compensated, further improving the sensitivity and reliability of pressure sensing. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] A pressure-sensing toilet seat comprises an upper cover 10, a lower cover 20, a foot pad 30 and a pressure sensor 40. The upper cover 10 of the seat is made of comfortable materials and ergonomically designed to ensure a good sitting feeling for the user. The lower cover 20 of the seat matches the upper cover 10 in shape, and the two are tightly combined by welding or other means to form an integrated one-piece structure to ensure durability and sealing. The lower cover 20 of the utility model has a cavity 21 protruding upward, and the cavity 21 is formed by the top wall 211 and the side wall 212. The foot pad 30 is fixedly installed in the cavity 21, and the pressure sensor 40 is fixed on the outer surface 211A of the cavity top wall 211. In order to optimize the transmission efficiency and accuracy of the pressure signal, a conductive column 22 is protruding downward on the inner surface 211B of the cavity top wall, and the conductive column 22 is against the foot pad 30. When the user sits on the seat, after the foot pad 30 is subjected to pressure, the pressure will be transmitted to the cavity top wall 211 through the conductive column in the first time, and then quickly transmitted to the pressure sensor. This solution ensures that the pressure sensor can capture the pressure changes of the user's seat in a timely and accurate manner. It not only improves the sensitivity and response speed of the sensing system, but also solves the energy loss and distortion problems in the pressure transmission process through the design of the conduction column, thereby providing users with a more accurate and consistent user experience.

[0028] Preferably, the foot pad 30 is disposed at the front end of the lower cover 20, that is, the foot pad is installed at the front position of the seat ring lower cover structure.

[0029] As shown in the figure, the pressure sensor 40 includes a sensor housing 41, which plays the role of protecting and supporting the sensor assembly. A special space is set inside the sensor to accommodate the detection circuit board, electronic components and related circuits. Usually, the pressure sensor 41 has an optimal sensing and conducting part 42, which refers to the key part in the sensor design for most effectively receiving, transmitting and converting pressure signals. Specifically for the pressure sensor of the toilet seat, the optimal sensing and conducting part usually refers to those parts that can respond to pressure changes most directly and sensitively, and can efficiently convert pressure information into electrical signals. In order to detect pressure changes more sensitively, the conductive column 22 in this embodiment is arranged directly below the optimal sensing and conducting part 42. Preferably, the optimal sensing and conducting part 42 is located at the center of the housing 41, and the center of the housing and the center of the outer surface of the top wall of the cavity are in the same vertical direction. This means that the positions of the two points are aligned in the vertical direction, which helps to ensure the directness and effectiveness of pressure transmission and avoid pressure sensing errors caused by position deviation.

[0030] Preferably, the pressure sensor 40 is placed vertically and crosswise with the cavity top wall 211, that is, if the cavity top wall 211 is arranged horizontally, the pressure sensor is arranged vertically, and the two are in vertical cross contact. Further, the pressure sensor housing 41 has a contact surface 411 opposite to the outer surface 211A of the cavity top wall, and the housing contact surface 411 corresponds to the conductive column 22 and is provided with a convex rib 43 protruding toward the cavity top wall 211. Preferably, the housing 41 is an axisymmetric structure, and the long axis of the convex rib 43 is in the same vertical direction as the axis of the housing 41. In this way, the contact and pressure conduction between the housing and the cavity top wall can be enhanced, and the effect of pressure conduction is optimized to a great extent in the vertical direction, so that the pressure sensor can more sensitively sense the pressure changes on the seat ring.

[0031] Regarding the fixing method of the pressure sensor, in this embodiment, a fixing column 23 is provided on the outside of the cavity of the seat ring lower cover, and the pressure sensor is pre-designed with a fixing hole 44 that matches the fixing column. The pressure sensor is inserted into the fixing column 23 through the fixing hole 44 and is locked to the lower cover 20 with a screw 50 to form a stable mechanical connection.

[0032] As for the pressure sensor, it can be judged that the human body has taken a seat by calculating the pressure deformation amount reaching a certain threshold. For example, when the user sits down, the pressure sensor on the seat ring starts to collect pressure data. Specifically, when the human body sits down, the pressure on the seat ring increases significantly, and components such as the elastic diaphragm or piezoresistive material inside the pressure sensor will deform due to pressure. The size of the deformation amount is proportional to the pressure. The electronic components inside the sensor will convert this deformation amount into an electrical signal, and process and calculate it through the corresponding circuit. Once the pressure value represented by this electrical signal reaches the preset threshold, the system can judge that the human body has taken a seat, which is manifested in the smart toilet as triggering the corresponding response, such as turning on flushing, heating and other functions. Therefore, by continuously monitoring and accurately calculating the deformation amount of the pressure sensor after being compressed, the smart toilet can accurately identify when the user sits down and make timely feedback, thereby realizing an intelligent user experience.

[0033] The utility model further provides an intelligent toilet, comprising a toilet body and the above-mentioned pressure-sensing toilet seat, wherein the toilet seat is rotatably attached to the toilet body.
