Description

Technical Field

[0001] This utility model relates to the field of smart toilet technology, and in particular to a smart toilet based on seat position detection. Background Technology

[0002] Smart toilet seats can offer a variety of functions, including heated seat, warm water washing, warm air drying, and sterilization and deodorization. Compared to traditional smart toilets, smart toilet seats offer advantages such as easy installation, lower cost, and higher cost-effectiveness.

[0003] After using the toilet, the user can activate the control panel or remote control to extend the cleaning hose inside the smart toilet seat. Once the hose is fully extended, the nozzle sprays water to clean the buttocks. This not only cleans effectively but also helps prevent bacterial infections, hemorrhoids, and constipation, offering advantages unmatched by ordinary toilets.

[0004] However, existing smart toilet seats use two types of water hoses: those with a fixed extension distance and those requiring manual adjustment by the user pressing a corresponding button. With the first type, due to differences in user body shape, age, sitting position, and posture, the extension distance of the cleaning nozzle cannot accurately align with the areas to be cleaned for each user. With the second type, operation is difficult for the elderly or children, making it easy to make mistakes and resulting in poor washing performance. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a smart toilet based on seat position detection.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides a smart toilet based on seat position detection, the toilet comprising:

[0008] The base contains a controller and a retractable water spray assembly.

[0009] A seat ring and a top cover, both of which are rotatably connected to the base;

[0010] A sensing component is installed on the toilet and is electrically connected to the controller. Several sensing components are equidistantly arranged along the contour line of the seat ring. When the sensing component detects user sitting information, it sends the sitting information to the controller. The controller adjusts the water spray component to spray water at different extension levels according to the number of user sitting information received.

[0011] The toilet further includes a detection component, which is disposed on the toilet and electrically connected to the sensing component. The detection component is used to detect whether a human body is sitting on the seat ring. When the detection component detects a human body, it activates the sensing component.

[0012] The advantages or beneficial effects of the above technical solutions include at least the following:

[0028] A smart toilet based on seat position detection, the toilet 10 includes:

[0029] The base 11 contains a controller and a retractable water spray assembly.

[0030] The seat ring 12 and the top cover 13 are rotatably connected to the base 11;

[0031] A sensor assembly is installed on the toilet 10 and electrically connected to the controller. Several sensors are equidistantly arranged along the contour line of the seat ring 12. When a sensor detects a user sitting down, it sends the information to the controller. The controller adjusts the spray nozzle to spray water at different extension levels based on the number of user sitting down information received. For example, if all five sensors receive the information, the extension is controlled at the first extension level; if four sensors receive the information, the extension is controlled at the second extension level; if three sensors receive the information, the extension is controlled at the third extension level; if two sensors receive the information, the extension is controlled at the fourth extension level; and if one sensor receives the information, the extension is controlled at the fifth extension level. The higher the extension level, the longer the extension length, so that the spray nozzle can adapt to different user sitting positions.

[0032] As a further improvement to the above structure, the toilet 10 further includes a detection component, which is disposed on the toilet 10 and electrically connected to the sensing component. The detection component is used to detect whether a human body is sitting on the seat ring 12. When the detection component detects a human body, it turns on the sensing component; otherwise, when no human body is detected, it turns off the sensing component to save power.

[0033] As a further improvement to the above structure, the detection component can be a first pressure sensor 21 or an infrared distance sensor 22, while the sensing component can be a second pressure sensor 31, a contact sensor 32 or a microwave sensor 33.

[0034] In the first embodiment, the detection component is a first pressure sensor 21, the sensing component is a microwave sensor 33 or a contact sensor 32, and in this embodiment, the height of the water jet from the water spray component is a first height.

[0035] Specifically, such as Figure 3 As shown, in the first embodiment, the detection component is a first pressure sensor 21, which is installed at the bottom of the front end of the seat ring 12. The base end of the first pressure sensor 21 is installed on the seat ring 12. When the seat ring 12 is flipped down, the pressure sensing end of the first pressure sensor 21 contacts the upper surface of the base 11. When a person sits on the seat ring 12, the weight of the person is transmitted to the first pressure sensor 21 through the seat ring 12. The first pressure sensor 21 senses the pressure at its pressure sensing end and determines that a person is sitting on the seat ring 12. The first pressure sensor 21 then activates the sensing component. Of course, in the first embodiment, the detection component can also be an infrared distance sensor 22, such as... Figure 1The infrared distance sensor 22 is installed on the top cover 13. When the top cover 13 is flipped up, the sensing direction of the infrared distance sensor 22 is towards the front end of the toilet 10. When the infrared distance sensor 22 senses a human body sitting on the seat ring 12, it activates the sensing component.

[0036] Furthermore, the sensing component is a microwave sensor 33, which is installed above the base 11 and several are evenly distributed along the edge of the seat ring 12. The sensing direction of the microwave sensor 33 is upward towards the base 11. The sensing range of the microwave sensor 33 extends through the seat ring 12 to detect the specific position of the human body sitting on the seat ring 12. The controller controls the water spray component to extend and retract to the corresponding position to spray water according to the position information. At this time, the water spray height of the component is the first height. In this embodiment, the sensing component does not need to be installed on the toilet seat ring 12. Similarly, as another implementation of the first embodiment, the sensing component can be a contact sensor 32.

[0037] In the second embodiment, the detection component is an infrared distance sensor 22, the sensing component is a second pressure sensor 31, and in this embodiment, the height of the water jet from the water spray component is a second height.

[0038] Specifically, the detection component is an infrared distance sensor 22, such as... Figure 1 The infrared distance sensor 22 is mounted on the top cover 13. When the top cover 13 is flipped up, the sensing direction of the infrared distance sensor 22 is towards the front end of the toilet 10, and when the seat ring 12 is flipped up, such as... Figure 4 As shown, the detection path of the infrared sensor passes through the gap in the middle of the seat ring 12, and the sensing range will not be blocked by the flipping of the seat ring 12. At the same time, the detection distance of the infrared distance sensor 22 is the distance from the top cover 13 to the front end of the base 11. Figure 5 As shown, this ensures that when the infrared distance sensor 22 detects a human body squatting on the base 11, the sensing component is activated.

[0039] Meanwhile, the sensing component is a second pressure sensor 31, which is mounted above the base 11 and has several units evenly distributed along the edge of the seat ring 12. The pressure sensing part of the pressure sensor is located on the upper surface of the base 11, such as... Figure 7As shown, the second pressure sensor 31 can detect the sitting point of a person squatting on the base 11. The controller calculates the extension and retraction of the water spray component based on the position of the sitting point. Therefore, when a person squats on the base 11, the seat ring 12 needs to be flipped up. Thus, it is advisable that the detection component is the infrared distance sensor 22 installed on the upper cover 13. If the person squats on the base 11, the buttocks are further away from the base 11 than when sitting on the seat ring 12. Therefore, in the second embodiment, the height of the water jet sprayed by the water spray component is the second height, which is higher than the first height, so that the water jet sprayed by the water spray component can reach the user's buttocks.

[0040] It should be noted that the triggering condition for the second height is: after the seat ring 12 is flipped up, the second pressure sensor 31 installed on the base 11 senses the pressure signal, thereby determining that a user is squatting on the base 11 to use the toilet. In addition, in the second embodiment, in addition to installing the second pressure sensor 31 on the base 11, a contact sensor 32 can also be installed on the seat ring 12. When the seat ring 12 is closed and the detection component detects the user, the second pressure sensor 31 is turned off.

[0041] Preferably, in the second embodiment, the detection component can also be a microwave distance sensor.

[0042] When the sensing component is a contact sensor 32 mounted on the seat ring 12, such as Figure 1 As shown, the array of contact sensors 32 is distributed at the rear and front of the seat ring 12. When a user sits on the seat ring 12, the user's buttocks come into contact with the contact sensors 32. The contact sensors 32 that receive the contact signal send the contact signal to the controller processor. For example, when the controller processor receives a contact signal from all the contact sensors 32, it determines that the user sitting on the seat ring 12 is an adult. At this time, the controller controls the extension and retraction of the water spray component according to the average body size of an adult. The extension and retraction is the first extension and retraction, so that the water spray component sprays accurately to the corresponding position. If the contact sensor 32 near the front of the seat ring 12 receives a contact signal, while the contact sensor 32 near the rear of the seat ring 12 does not receive a contact signal, for example, only 3 out of 5 sensors receive a signal, then the controller determines that the user is a minor. At this time, the controller controls the extension and retraction of the water spray component according to the average body size of a minor. The extension and retraction is the second extension and retraction. The first extension and retraction is less than the second extension and retraction. Compared to an adult, the extension and retraction of the water spray component will be greater when a minor uses it than when an adult uses it.

[0043] When the sensing component is a microwave sensor 33 mounted on the base 11, such as Figure 6As shown, the array of microwave sensors 33 is distributed at the rear and front of the base 11. The microwave sensors 33 determine the position of the user's buttocks when sitting on the seat ring 12 based on the strength of the received signal. When the signal strength of the microwave sensor 33 is higher than the threshold, it sends the signal to the controller. For example, when the controller processor receives the signals sent by all the microwave sensors 33, it determines that the user sitting on the seat ring 12 is an adult. At this time, the controller controls the extension and retraction of the water spray component according to the average body size of an adult, so that the water spray component sprays accurately to the corresponding position. If the microwave sensor 33 near the front of the seat ring 12 sends a signal, but the microwave sensor 33 near the rear of the seat ring 12 does not send a signal, for example, only 3 out of 5 sensors receive a signal, then the controller determines that the user is a minor. At this time, the controller controls the extension and retraction of the water spray component according to the average body size of a minor. The extension and retraction is the second extension and retraction, which is smaller than the first extension and retraction. Compared with an adult, the extension and retraction of the water spray component will be greater when a minor uses it than when an adult uses it.

[0044] When the sensing component is the second pressure sensor 31, the judgment method differs from that described above, such as... Figure 7 As shown, the second pressure sensor 31 array is arranged on the base 11. If the second pressure sensor 31 receives a pressure signal, it sends the signal to the controller. At this time, the controller determines the user's sitting point on the base 11 based on the position of the second pressure sensor 31 that sent the information, and adjusts the extension and retraction of the water spray assembly accordingly. Specifically, the further forward the sitting point is, the greater the extension and retraction, and vice versa, so that the water spray assembly can accurately spray to the corresponding position.

[0045] To achieve multiple modes for the Toilet 10, such as Refreshing Wash, Gentle Wash, and Child Wash, multiple spray nozzles can be created on the spray pipe of the spray assembly. For example, there can be a first spray nozzle for washing, a second spray nozzle for washing, and a third spray nozzle for child washing. Since the washing positions, water flow angles, and water flow patterns differ between washing and washing, the opening angles of the first spray nozzle for washing and the second spray nozzle for washing can be designed separately. Similarly, the opening angle of the third spray nozzle can be designed specifically for child washing, allowing water jets from different nozzles to wash different parts of the user's body, thus achieving a better user experience.
