Description

Technical Field

[0001] The present invention relates to the technical field of bathroom induction switches, and specifically to a seat sensing switch based on the principle of pressure recognition. Background Technique

[0002] The toilet is a common bathroom product in daily life. With the development of the times, modern toilets have more functions, and heated toilet seats can be found in many smart toilets.

[0003] A common type of heated toilet seat currently includes a housing, a heating layer, and a switch provided on the housing. The switch is used to control the opening and closing of the heating layer. The heating layer is fixedly arranged on the lower surface of the housing. When heating is required, the switch is manually turned on to allow the heating layer to heat, thereby heating the housing and providing comfort for the user.

[0004] For the above technical conditions, there are still defects. Due to the special nature of the toilet, there is an unpleasant smell. When the switch needs to be turned on, one also needs to bend down and manually touch the switch, which is a cumbersome process and a challenge for people with cleanliness issues, resulting in the inconvenience of turning on the heating switch.

[0005] Based on this, the present invention designs a seat sensing switch based on the principle of pressure recognition to solve the above problems. Summary of the Invention

[0006] To achieve the above object, the present invention provides the following technical solution: A seat sensing switch based on the principle of pressure recognition, including a housing, a mounting seat, and a pressure sensor. The mounting seat is fixedly arranged on the housing. An installation groove is provided on the mounting seat. The pressure sensor includes a detection piece and a processor. The detection piece and the processor are respectively fixedly arranged in the installation groove. A communication groove is provided on the detection piece, and a test board is fixedly arranged in the communication groove. A connection plate is arranged on the mounting seat. A connection block is fixedly arranged on the lower side of the connection plate, and the lower side of the connection block abuts against the test board. A control panel is arranged in the mounting seat. The processor is electrically connected to the control panel, and the control panel is electrically connected to the switch of the heating layer of the toilet seat. When the pressure sensor detects pressure, the control panel controls the switch of the heating layer to be turned on.

[0007] By adopting the above technical solution, when using the toilet, press down on the toilet seat. At this time, the pressure sensor senses the change in pressure and the value exceeds the set value. At this time, the pressure sensor sends a signal to the control panel, and the control panel controls the switch of the heating layer to be turned on, allowing the heating layer to heat, without the need to manually touch the switch for heating, facilitating the opening of the heating layer switch and achieving the effect of automatic heating.

[0008] Preferably, a stabilizing plate is fixedly arranged on the connection block, and the stabilizing plate is inserted into the communication groove.

[0009] By adopting the above technical solution, the stabilizing plate is inserted into the connecting groove, reducing the movement of the connecting block and stabilizing the placement of the connecting block.

[0010] Preferably, a sealing ring is fixedly arranged on the mounting seat, and the sealing ring abuts against the outer shell.

[0011] By adopting the above technical solution, the sealing ring can improve the sealing effect and reduce the entry of moisture into the outer shell.

[0012] Preferably, a heat insulation layer is fixedly arranged on the mounting seat.

[0013] By adopting the above technical solution, the heat insulation layer can improve the heat insulation effect of the mounting seat, reduce the heat of the heating layer from entering the outer shell, and thus improve the accuracy of the pressure sensor.

[0014] Preferably, after the pressure sensor detects a pressure change and the detected value exceeds the specified value for 3 seconds, the control panel controls the heating layer switch to turn on for heating.

[0015] By adopting the above technical solution, it is avoided that the toilet seat starts to heat up when accidentally touched, thus reducing energy consumption.

[0016] Preferably, when the pressure sensor does not detect a pressure change, after receiving the signal, the control panel delays for 5 seconds and then controls the heating layer switch to turn off to stop heating.

[0017] By adopting the above technical solution, when the pressure change is re-sensed within 5 seconds, the toilet seat does not stop heating, and it stops after more than 5 seconds, avoiding the closing of the toilet seat caused by the user standing up or other transient detachment from the toilet seat, and reducing the number of starts and stops.

[0018] Preferably, when the pressure sensor does not detect a pressure change, within 5 seconds, the control panel controls the heating layer switch to operate at a maintenance power lower than the rated heating power for heating.

[0019] By adopting the above technical solution, heating is carried out at the lowest power, reducing energy consumption while maintaining a certain temperature.

[0020] Preferably, the control panel records the time points when the user sits down every day, and during the periods when the user often uses it, the control panel controls the heating layer switch to turn on for preheating.

[0021] By adopting the above technical solution, preheating is carried out in advance before use, improving the comfort of the user's buttocks.

[0022] In summary, the present application has the following beneficial technical effects: By adopting the above technical solution, when using the toilet, press down the toilet seat cushion. At this time, the pressure sensor senses the change in pressure and the value exceeds the set value. At this time, the pressure sensor emits a signal to the control panel, and the control panel controls the switch of the heating layer to be turned on, allowing the heating layer to heat up. There is no need to manually touch the switch to heat up, which is convenient to turn on the switch of the heating layer and achieve the effect of automatic heating.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0027] The following further Figures 1-5 details this application.

[0028] Refer to Figures 1-5, A seating induction switch based on the principle of pressure recognition, including a housing 1, a mounting base 2, and a pressure sensor. The housing 1 is fixedly arranged at the position of the toilet seat close to the buttocks. The mounting base 2 is fixedly arranged on the housing 1. An installation groove 4 is formed on the mounting base 2. The pressure sensor includes a detection piece 5 and a processor 6. A support block 7 is fixedly arranged in the installation groove 4. There are multiple support blocks 7. The detection piece 5 is fixedly arranged on the multiple support blocks 7. The processor 6 is fixedly arranged in the installation groove 4; A communication groove 8 is formed on the detection piece 5. A test board 9 is fixedly arranged in the communication groove 8. When the test board 9 deforms, at this time, the processor 6 generates a corresponding signal according to the deformation of the test board 9; Refer to Figures 1-5 , A connecting plate 10 is arranged on the mounting base 2. A connecting block 11 is fixedly arranged on the lower side of the connecting plate 10. The lower side of the connecting block 11 abuts on the test board 9. A stabilizing plate 12 is fixedly arranged on the connecting block 11. The stabilizing plate 12 is inserted into the communication groove 8. There are two corresponding stabilizing plates 12. The test board 9 is located between the two stabilizing plates 12. When the connecting block 11 is placed on the test board 9, the test board 9 can reduce the running of the connecting block 11 and make the connecting block 11 stably placed on the test board 9; Refer to Figures 1-5 , A control panel 13 is arranged in the mounting base 2. The processor 6 is electrically connected to the control panel 13. The control panel 13 is electrically connected to the switch of the heating layer of the toilet seat. In this embodiment, the toilet is powered by an external power supply such as household electricity; After the pressure sensor detects a pressure change, when the detected change value exceeds the specified value for 3 seconds and the value continuously exceeds the specified value during this period, at this time, the control panel 13 controls the heating layer switch to turn on for heating; Detecting the existence of pressure for 3 seconds can avoid false instructions output due to the vibration of the toilet seat when the toilet seat is turned up or placed, so as to more intelligently judge the usage situation of the toilet and reduce the waste of energy consumption.

[0029] Refer to Figures 1-5 , When the pressure sensor does not detect a pressure change, after receiving the signal, the control panel 13 controls the heating layer switch to turn off and stop heating after a delay of 5 seconds. Within 5 seconds, the control panel 13 controls the heating layer switch to operate at a maintenance power lower than the rated heating power for heating; If the pressure changes are sensed again within 5 seconds, at this time, the control panel 13 continues to control the heating layer switch to turn on and let the heating layer continue to heat; Heating is carried out at the lowest power to reduce energy consumption while maintaining a certain temperature; When the pressure changes are sensed again within 5 seconds, the toilet seat does not stop heating and stops after more than 5 seconds, avoiding the closing of the toilet seat caused by the user standing up or other transient detachment from the toilet seat, reducing the number of starts and stops, and improving the service life.

[0030] Refer to Figures 1-5, when using the toilet, the buttocks are seated on the toilet seat cushion, pressing down on the connecting plate 10, the connecting block 11 presses down on the test plate 9, and the processor 6 detects the pressure change on the detection piece. When the pressure change is sensed and the value exceeds the set value, a signal is sent to the control panel 13. The control panel 13 controls the switch of the heating layer to turn on, allowing the heating layer to heat up. There is no need to manually touch the switch to heat, which is convenient for turning on the heating layer switch and achieving the effect of automatic heating.

[0031] Refer to Figures 1-5 , the control panel 13 records the time points when the user sits down every day. During the periods when the user often uses the toilet, for example, from 7:00 to 8:00 in the morning, the control panel 13 pre-opens the switch of the heating layer in advance, allowing the heating layer to pre-heat in a low-power state. When in use, it speeds up the speed at which the toilet seat cushion reaches the required temperature, thereby improving the comfort of the user's buttocks.

[0032] Refer to Figures 1-5 , a fixing groove 14 is formed on the mounting seat 2, and a sealing ring is sleeved on the fixing groove 14. The sealing ring in this embodiment is made of silica gel. When the mounting seat 2 is located in the outer shell 1, the sealing ring abuts against the outer shell 1 at this time, clamping the mounting seat 2, thereby fixing the mounting seat 2 on the outer shell 1, which is convenient for the installation of the mounting seat 2; the sealing strip can also improve the sealing effect and reduce the entry of moisture into the outer shell 1.

[0033] Refer to Figures 1-5 , a heat insulation layer 3 is fixedly arranged on the mounting seat 2. The heat insulation layer 3 can improve the heat insulation effect of the mounting seat 2, reduce the heat of the heating layer from entering the outer shell 1, and thus improve the accuracy of the pressure sensor.

[0034] The implementation principle of this embodiment is: when using the toilet, pressing down on the toilet seat cushion. At this time, the pressure sensor senses the pressure change and the value exceeds the set value. At this time, the pressure sensor emits a signal to the control panel 13. The control panel 13 controls the switch of the heating layer to turn on, allowing the heating layer to heat up. There is no need to manually touch the switch to heat, which is convenient for turning on the heating layer switch and achieving the effect of automatic heating.
