Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to a smart toilet capacitive sensor and a smart toilet that are easy to install and remove. Background Technology

[0002] A capacitive sensor is a sensing device installed on a smart toilet. It uses the principle of capacitive sensing to detect the approach or contact of a person's feet, hands, or other parts, thereby triggering the toilet's automatic functions such as opening the lid, flipping the seat, closing the lid, and flushing.

[0003] A capacitive sensor contains one or more capacitive sensors. When a person's foot or hand approaches or touches the sensing area, because the human body is a conductor, a capacitance is formed between it and the sensor. The value of this capacitance changes with the distance or degree of contact between the person and the sensor. The circuitry inside the sensor detects this change in capacitance to determine whether a foot has approached or touched the sensor, thereby triggering the corresponding toilet operation.

[0004] Currently, capacitive sensors on smart toilets are typically installed in two ways. The first method involves directly attaching the sensor to the inner wall of the toilet bowl with adhesive. This method is inconvenient to remove, requiring considerable force to detach the sensor from the side wall. The second method involves attaching the sensor to the inner wall of the smart toilet bowl using a bracket and adhesive, with the sensor housed in a bracket slot. However, this method lacks a positioning structure between the sensor and the bracket slot, making it difficult for the operator to precisely control the depth of the sensor within the slot. This can easily lead to the sensor being installed too deeply or inaccurately. Such over-installation may not only affect the sensor's sensitivity and accuracy but may also damage its internal structure or result in poor adhesion to the toilet bowl wall. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a smart toilet capacitive sensor and a smart toilet that are easy to assemble and disassemble, which can effectively solve the problems existing in the prior art.

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

[0007] According to one aspect of the present invention, the device includes: a support groove and a capacitive sensor, wherein the support groove is sleeved outside the capacitive sensor, and further includes a positioning groove and a positioning protrusion that cooperate with each other. At least one positioning protrusion is provided on the front end face and / or rear end face of the capacitive sensor extending toward the support groove, and at least one positioning groove is provided on the support groove accordingly. When the capacitive sensor is assembled in the support groove, the positioning protrusion is engaged in the positioning groove.

[0008] Furthermore, the rear end face of the bracket groove is provided with a notch for avoiding the power line of the capacitive sensor; it also includes at least one limiting plate, the supporting groove extends towards the notch and the limiting plate is provided, the positioning groove is provided on the limiting plate, and the positioning protrusion is correspondingly provided on the rear end face of the capacitive sensor.

[0009] Furthermore, the positioning groove is provided with ribs, which divide the positioning groove into two slots; there are multiple positioning protrusions, and the multiple positioning protrusions are respectively engaged in each slot.

[0010] Furthermore, a gap is formed between the upper or lower end of the rib and the positioning groove.

[0011] Furthermore, there are two limiting plates, which are symmetrically arranged at the upper and lower ends of the notch.

[0012] Furthermore, it also includes an adhesive, which is fixed to the front end face of the bracket groove to adhere it to the toilet.

[0013] Furthermore, the support groove has openings at both the left and right ends to allow the capacitive sensor to pass through.

[0014] Furthermore, it also includes at least two guide plates, which are respectively inclined and fixed at the upper and lower ends of one of the openings, and both openings are fixed with guide plates.

[0015] Furthermore, the limiting plate is provided with a guide groove near the opening to guide the positioning protrusion.

[0016] According to another aspect of the present invention, a smart toilet includes a toilet and a smart toilet capacitive sensor as described above, which is easy to install and remove. The smart toilet capacitive sensor is attached to the inner wall of the toilet by adhesive.

[0017] By adopting the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows:

[0018] Firstly, the cooperation between the positioning protrusion and the positioning groove ensures that the capacitive sensor is accurately positioned within the bracket groove. This design avoids the problem of the sensor being installed too deep or misaligned, thus improving installation accuracy. An accurate installation position helps ensure the sensing sensitivity and accuracy of the capacitive sensor. With the positioning structure, the operator does not need to adjust the sensor position excessively during installation; simply align the positioning protrusion with the positioning groove. This greatly simplifies the installation process and improves work efficiency.

[0019] Secondly, during the manufacturing process of the bracket slot and the capacitive sensor, there may be dimensional tolerances. The gap allows for some movement at both the upper and lower ends of the capacitive sensor when it is installed in the bracket slot, which facilitates the installation of the capacitive sensor.

[0020] Third, the limiting plate is provided with a guide groove near the opening to guide the positioning protrusion, which facilitates the assembly of the capacitive sensor. Attached Figure Description
