[0032] Combine the following Figure 1-5 The utility model is described in detail.

[0033] The utility model provides a sensing device 10 for use in electronic equipment. The sensing device 10 includes a sensing module 401 and an amplifying module 402. The circuit diagram is shown in FIG. Figure 2As shown, the capacitance value of the capacitor C1 determines the sensitivity of the sensing device, and the range of its capacitance value is 1-6pF. The smaller the capacitance value, the more sensitive the sensing. Specifically, the capacitance value of the capacitor C1 is 5.6pF. The sensing module 401 is supported on the electronic device, which is used to transmit a first sensing signal to sense the information in the first area. The amplification module 402 is at least partially arranged on a partial path of the first sensing signal to switch the first sensing signal from the sensing first area to the sensing second area, and the distance between the second area and the signal transmitting device of the sensing module 401 is greater than the distance between the first area and the signal transmitting device. Through the amplification module 402, the sensing distance of the existing sensing device 10 is extended without adjusting the dielectric constant, which solves the undesirable conditions such as oversensitive sensing and freezing caused by adjusting the dielectric constant, and the sensing distance increased by the amplification module 402 is greater than the sensing distance increased by adjusting the dielectric constant.

[0034] In this embodiment, the amplifying module 402 is made of a conductive material, specifically, the amplifying module 402 is a sensing key spring or conductive cotton. The sensing device 10 further includes a PCB board 30, and the PCB board 30 is provided with a sensing module 401 and an amplifying module 402. The PCB board 30 is encapsulated in the housing 20 by a potting glue 80, and the PCB board 30 is provided with a lead 70 electrically connected to the potting glue 80.

[0035] In this embodiment, the sensing device 10 is provided with an indicator light 50. Specifically, the indicator light 50 is provided on the PCB board 30. The housing 20 is provided with a light exit hole for the indicator light 50 to emit light. The light exit hole is adapted to the radiation channel 4021, so that the light emitted by the indicator light 50 passes through the radiation channel 4021 and the light exit hole in sequence and then transmits to the ground, forming a light spot 60 with an area not larger than the second area. The shape and color of the light spot 60 can be adjusted according to different usage requirements. In addition, the light spot 60 can also transmit guiding text to the ground to guide the user to put his foot into the area of ​​the light spot 60 to activate the sensing module 401.

[0036] The utility model further provides a toilet, comprising a toilet body 90, and a sensing device 10 supported on the toilet body 90, wherein the sensing device 10 comprises a sensing module 401 and an amplifying module 402, specifically:

[0037] A sensing module 401 configured to transmit a first sensing signal to an external space of the toilet body 90 and sense information in a first area; and

[0038] The amplifying module 402 is at least partially disposed on a partial path of the first sensing signal to switch the first sensing signal from sensing the first area to sensing the second area, and the distance between the second area and the signal transmitting device of the sensing module 401 is greater than the distance between the first area and the signal transmitting device.

[0039] Therefore, the present toilet includes the beneficial effects of the aforementioned sensing device 10, and the sensing device 10 is configured to emit a first sensing signal to the external space of the toilet body 90, so that the toilet has a longer sensing distance and stability compared to the prior art, thereby improving the user experience.

[0040] In this embodiment, the sensing device 10 is arranged at the front end or one side of the toilet body 90, so that the light spot 60 projected by the sensing device 10 is located on the ground at the front end or one side of the toilet body 90, and the front end or one side of the toilet body 90 is provided with a mounting hole 901 for mounting the sensing device 10. Specifically, the mounting hole 901 is arranged on one side of the toilet body 90, and after the sensing device 10 is mounted on the mounting hole 901, the angle α between the emission direction of the first signal and the ground is in the range of 55-75 degrees, such as Figure 5 shown.

[0041] In this embodiment, the amplification module 402 is provided with a radiation channel 4021. The angle between the radiation channel 4021 and the ground determines the emission direction of the first signal. Therefore, the angle between the radiation channel 4021 and the ground is 55-75 degrees. When in use, the first sensing signal can be switched from the first sensing area to the second sensing area after passing through the radiation channel 4021. Specifically, the opening degree of the radiation channel 4021 along the emission direction of the first signal is positively correlated with the radiation range and distance of the first signal, that is, the larger the opening degree of the radiation channel 4021 along the emission direction of the first signal, the larger the radiation range and distance of the first signal.

[0042] In this embodiment, a control device is provided in the toilet body 90, and the control device is communicatively connected to the sensing device 10. The toilet body 90 is also provided with an execution device, and the execution device is communicatively connected to the control device. The control device starts the execution device based on whether the sensing device 10 senses information in the second area. The execution device includes but is not limited to a flushing device, a flip device or a ring turning device. As long as the user extends his foot into the area of ​​the light spot 60, the sensing module 401 receives an actuation signal, and the flushing device, flip device or ring turning device can be started through the control device, realizing contactless operation throughout the process, thereby improving the user experience.

[0043] The toilet proposed in the utility model, taking the flushing device as an example, its working principle is as follows:

[0044] The indicator light 50 transmits a light spot 60 to the ground. When the user needs to flush after defecation, he only needs to extend his foot into the area of ​​the light spot 60. The sensing device 10 can sense the action signal, and then send a start signal to the flushing device through the controller, and then flush the toilet, realizing contactless operation and improving the user experience.

[0045] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
