Description

TECHNICAL FIELD

[0001] The utility model relates to the field of bathroom technology, more particularly, a toilet and its sensing device. BACKGROUND

[0002] Currently, some toilets need to be provided with a light sensing module to measure the intensity of ambient light. However, the selection of the setting position of the light sensing module has always been an industry problem. For example, if the light sensing module is set in the electronic cover of the toilet, an opening needs to be added on the electronic cover; if the light sensing module is set above or in front of the electronic cover, it will affect the appearance of the toilet; if the light sensing module is placed behind the electronic cover, it will not be able to accurately measure the intensity of ambient light because the light is relatively dark when the toilet is against the wall.

[0003] In particular, the light sensing module is a small device, which is not easy to waterproof and has poor stability. At the same time, the addition of the light sensing module also requires a separate host port and data line for the light sensing module, which will increase the production cost. SUMMARY

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0047] like Figure 1 , 2 As shown, Figure 1 , 2 A sensing device 1 integrating foot sensing and light sensing is shown in an embodiment of this application. The sensing device 1 is applied to a toilet 100. The sensing device 1 includes a housing 11, a circuit module 12, and an encapsulating colloid (not shown).

[0048] like Figure 3 , 4 As shown, the housing 11 can be constructed as a barrel shape. The housing 11 has an inner cavity. One end of the housing 11 has an opening 111, which communicates with the inner cavity.

[0049] Circuit module 12 includes circuit board 120, foot sensor module 121, and light sensor module 122. Circuit board 120 may be a printed circuit board. Circuit board 120 may be configured as a generally disk-shaped board. Circuit board 120 covers and seals opening 111 of housing 11. One side of circuit board 120 faces the inner cavity of housing 11, and the other side faces away from the inner cavity of housing 11. Foot sensor module 121 and light sensor module 122 are both disposed on the side of circuit board 120 facing the inner cavity. Both foot sensor module 121 and light sensor module 122 are located inside the inner cavity of housing 11. Foot sensor module 121 is used to detect whether a human foot is located within its detection area 1210. Light sensor module 122 is used to detect the intensity of ambient light.

[0050] The encapsulating colloid is transparent. The encapsulating colloid is formed by the curing of encapsulating adhesive injected into the inner cavity of the housing 11. The encapsulating colloid fills the inner cavity of the housing 11. The encapsulating colloid may completely fill the inner cavity. Alternatively, the encapsulating colloid may only partially fill the injection cavity; for example, the encapsulating colloid may be a layered structure covering the circuit board 120, the foot sensing module 121, and the light sensing module 122. The encapsulating colloid covers the foot sensing module 121 and the light sensing module 122.

[0051] The encapsulating colloid isolates the foot sensor module 121 and the light sensor module 122 from the air, preventing damage to them in high-humidity environments and improving their waterproof and moisture-proof capabilities. Furthermore, encapsulating the foot sensor module 121 and the light sensor module 122 into a single module saves on the use of mechanical and electronic components, reducing the production cost of the toilet 100 and improving system reliability.

[0052] In one illustrative embodiment, circuit module 12 further includes a data line 123. Data line 123 may be a single-wire bus. Data line 123 is electrically connected to foot sensing module 121 and light sensing module 122. Foot sensing module 121 and light sensing module 122 transmit electrical signals via data line 123 using a single-wire communication protocol. Foot sensing module 121 and light sensing module 122 transmit detection results to the host computer via data line 123.

[0053] In this way, the foot sensor module 121 and the light sensor module 122 can share a data line 123 to transmit electrical signals, which can save the host port and data line 123.

[0054] In one illustrative embodiment, the foot sensing module 121 includes a laser emitter 1211 and a laser receiver 1212. Both the laser emitter 1211 and the laser receiver 1212 are soldered to the surface of the circuit board 120 facing the inner cavity of the housing 11.

[0055] A laser inlet 113 and a laser outlet 112 are provided at the end of the housing 11 facing away from its opening 111. The laser inlet 113 and laser outlet 112 are through holes penetrating the housing 11. Both the laser inlet 113 and laser outlet 112 are connected to the inner cavity of the housing 11. A laser emitter 1211 is positioned near the laser inlet 113, and a laser receiver 1212 is positioned near the laser outlet 112. The laser emitter 1211 is configured to emit laser light through the laser outlet 112 of the housing 11 towards a detection area 1210 outside the housing 11. The laser receiver 1212 is configured to sense reflected laser light entering the inner cavity of the housing 11 from the laser inlet 113 of the housing 11.

[0056] In this way, the laser emitter 1211 emits a laser, which passes through the laser outlet 112 and is directed towards the detection area 1210 outside the housing 11. If the human foot is located in the detection area 1210, the laser will be diffusely reflected after hitting the foot. Part of the reflected laser can be directed towards the laser inlet 113 of the housing 11 and enter the inner cavity of the housing 11 through the laser inlet 113, and then be directed towards the laser receiver 1212. The laser receiver 1212 receives the reflected laser and can sense the reflected laser, thereby determining that there is a foot in the detection area 1210.

[0057] The light sensing module 122 includes a photosensitive sensor 1221. The photosensitive sensor 1221 is soldered to the surface of the circuit board 120 facing the inner cavity of the housing 11. A light-sensing inlet 115 is also provided at the end of the housing 11 facing away from its opening 111. The light-sensing inlet 115 is a through-hole penetrating the housing 11. The photosensitive sensor 1221 is located near this light-sensing inlet 115. The photosensitive sensor 1221 is configured to detect the intensity of light entering the inner cavity of the housing 11 from the light-sensing inlet 115.

[0058] Ambient light around the toilet 100 enters the inner cavity through the light inlet 115 and then strikes the photosensitive sensor 1221. When the photosensitive sensor 1221 is illuminated, it undergoes a photoelectric effect and generates an electrical signal. Thus, the photosensitive sensor 1221 can convert the sensed ambient light into an electrical signal. The stronger the light, the stronger the electrical signal. The strength of the electrical signal output by the photosensitive sensor 1221 can characterize the intensity of the ambient light.

[0059] In one illustrative embodiment, such as Figure 4 , 6 As shown, the foot sensor module 121 also includes an indicator light 1213. The indicator light 1213 can be an LED. The indicator light 1213 is disposed on the surface of the circuit board 120 facing the inner cavity, and is located within the inner cavity of the housing 11. The indicator light 1213 is encapsulated with encapsulant. The encapsulant isolates the indicator light 1213 from air, improving its waterproof and moisture-proof capabilities.

[0060] The circuit board 120, on which the indicator light 1213 is located, faces diagonally downwards. The indicator light 1213 emits light diagonally downwards, and the laser emitter 1211 emits laser light diagonally downwards.

[0061] The housing 11 also has an indicator light outlet 114 at the end opposite to its opening 111. The indicator light outlet 114 is a through hole penetrating the housing 11. An indicator light 1213 is positioned near the indicator light outlet 114. The indicator light 1213 is configured to emit light toward the indicator light outlet 114 and illuminate the ground with the light emitted from the indicator light outlet 114 to display the detection area 1210 on the ground.

[0062] When indicator light 1213 emits light diagonally downwards, a portion of the light shines onto the ground through indicator light outlet 114, forming a light spot. Laser emitter 1211 emits laser light towards this light spot, which coincides with the detection area 1210 of foot sensor module 121, thus displaying the detection area 1210 of foot sensor module 121. The user can see this light spot and step on it to trigger foot sensor module 121.

[0063] In one illustrative embodiment, the indicator light 1213 and the light sensing module 122 are configured not to operate simultaneously.

[0064] The working times of the indicator light 1213 and the light sensing module 122 are staggered. For example, the foot sensing module 121 and the light sensing module 122 work alternately. This can prevent the light emitted by the indicator light 1213 from interfering with the detection results of the light sensing module 122.

[0065] In one illustrative embodiment, the sensing device 1 further includes a base 13. The base 13 includes a base 131 and a plurality of support portions 132. The base 131 is disposed on the side of the circuit board 120 facing away from the housing 11. The base 131 is connected to the housing 11. The base 131 and the housing 11 may be connected by a snap-fit ​​connection. The plurality of support portions 132 may be arranged in a strip shape. All of the plurality of support portions 132 extend from the base 131 toward the circuit board 120. The plurality of support portions 132 are spaced apart. The ends of the plurality of support portions 132 facing away from the base 131 abut against the surface of the circuit board 120 facing away from the inner cavity. The end face of the support portion 132 facing away from the base 131 is constructed as an inclined end face, which is parallel to the surface of the circuit board 120.

[0066] In this way, the multiple support parts 132 can jointly support the circuit board 120, so that the circuit board 120 will not detach from the housing 11.

[0067] In one illustrative embodiment, the sensing device 1 further includes a housing 14. The housing 14 includes a cylindrical body 141 and a light-transmitting plate 142. The cylindrical body 141 may be constructed as a cylinder. The cylindrical body 141 includes a first end 1411 and a second end 1412, which are disposed opposite to each other. The light-transmitting plate 142 may be made of a transparent material. The light-transmitting plate 142 may be constructed as a circular flat plate. The light-transmitting plate 142 covers and seals the first end 1411 of the cylindrical body 141. The diameter of the light-transmitting plate 142 is larger than the diameter of the cylindrical body 141. The light-transmitting plate 142 and the cylindrical body 141 may be connected by screws or adhesive. The cylindrical body 141 houses the housing 11, the circuit module 12, and the encapsulating colloid. One end of the housing 11, which is provided with a light inlet 115, a laser inlet 113, and a laser outlet 112, faces the light-transmitting plate 142. The base 131 of the base 13 is connected to the second end 1412 of the cylinder 141, and the base 131 of the base 13 and the second end 1412 of the cylinder 141 can be connected by a snap-fit. The base 131 of the base 13 blocks the second end 1412.

[0068] In this way, the outer casing 14 covers the outer casing 11, providing further protection for the circuit module 12 and further improving the waterproof performance. At the same time, laser, ambient light and lamp light can be transmitted through the light-transmitting plate 142, and the outer casing 14 will not block the laser, ambient light and lamp light, and will not affect the foot detection function and ambient light detection function of the sensing device 1.

[0069] In one illustrative embodiment, the base 131 is arranged in annular shape and located within the second end 1412. The base 131 and the second end 1412 are coaxially arranged. A limiting groove is provided on the outer peripheral wall of the base 131. The limiting groove is annular and surrounds the base 131.

[0070] The sensing device 1 also includes a sealing ring 16. The sealing ring 16 is fitted onto the base 131. The sealing ring 16 is clamped within a limiting groove. The inner edge of the sealing ring 16 abuts against the outer peripheral wall of the base 131. The outer edge of the sealing ring 16 abuts against the inner peripheral wall of the second end 1412 of the cylinder 141. The sealing ring 16 seals the gap between the outer peripheral wall of the base 131 and the inner peripheral wall of the second end 1412 of the cylinder 141.

[0071] like Figure 5 , 6As shown, this embodiment also proposes a toilet 100, which includes the sensor 1 and seat 2 as described above. The seat 2 may be made of ceramic. The seat 2 is the main body of the toilet 100. A mounting hole 21 is provided at the front of the seat 2. The mounting hole 21 may be located at the front of the seat 2 or on the side of the front of the seat 2. The mounting hole 21 may be located at a position of the seat 2 near the ground. The sensor 1 is disposed in the mounting hole 21. The light-transmitting plate 142 of the sensor 1 is located on the outside of the seat 2.

[0072] The front of the toilet 100 is usually well lit, which can reflect the brightness of the ambient light around the toilet 100. By placing the sensor 1 at the front of the toilet 100, the light sensor module 122 can accurately detect the intensity of the ambient light, and the foot sensor module 121 can also detect the feet.

[0073] In one illustrative embodiment, the sensing device 1 further includes an elastic sleeve 15. The elastic sleeve 15 may be made of rubber or silicone and is elastic. The elastic sleeve 15 is constructed as a cylindrical structure. The elastic sleeve 15 is fitted onto the cylindrical body 141. The central region of the elastic sleeve 15 is radially arched outward to form a limiting protrusion 151.

[0074] When installing the sensor 1, it can be inserted into the mounting hole 21 of the base 2. The limiting protrusion 151 of the elastic sleeve 15 is squeezed by the hole wall of the mounting hole 21 and undergoes elastic deformation and retracts inward, allowing the limiting protrusion 151 to pass through the mounting hole 21. After the limiting protrusion 151 of the elastic sleeve 15 fully reaches the inside of the mounting hole 21, it returns to its arched state. At this time, the limiting protrusion 151 is stuck inside the mounting hole 21, ensuring that the sensor 1 cannot be dislodged from the mounting hole 21, so that the sensor 1 can be stably installed on the base 2.

[0075] In one illustrative embodiment, an annular groove 1413 is provided on the outer peripheral wall of the cylinder 141. The annular groove 1413 surrounds the cylinder 141. The annular groove 1413 may be located at the first end 1411 of the cylinder 141. The elastic sleeve 15 is partially embedded in the annular groove 1413.

[0076] In this way, the elastic sleeve 15 is partially embedded in the annular groove 1413, and the elastic sleeve 15 is limited by the annular groove 1413 and cannot move axially relative to the cylinder 141, thereby making the elastic sleeve 15 and the cylinder 141 more tightly connected.

[0077] In one illustrative embodiment, the sensing device 1 also includes a decorative cover 17. The decorative cover 17 is annular in shape. The decorative cover 17 is fitted onto the housing 14. The decorative cover 17 covers the outer edge of the light-transmitting plate 142.

[0078] In this way, the decorative cover 17 can prevent the edges of the light-transmitting plate 142 from being exposed, thus improving the overall aesthetics of the sensing device 1.

[0079] This application also proposes a control method for the sensing device 1, which includes the following steps:

[0080] Step S1: Power on circuit module 12 and proceed to step S2;

[0081] Step S2: Indicator light 1213 stays on for 4-6 seconds, or 5 seconds, and controls foot sensor module 121 to detect whether the human foot is in its detection area, then proceeds to step S3.

[0082] Step S3: The indicator light is off for 0.5 to 1.5 seconds, or 1 second, and the light sensor module 122 is controlled to detect the intensity of the ambient light, then proceed to step S4;

[0083] Step S4: Determine whether the intensity of the ambient light detected by the light sensor module 122 is greater than or equal to the preset intensity. If yes, proceed to step S2; otherwise, proceed to step S5.

[0084] Step S5: Determine whether the number of times the ambient light intensity detected by the light sensor module 122 is less than the preset intensity is greater than or equal to 1800 times. If yes, proceed to step S6; otherwise, proceed to step S2.

[0085] Step S6: The indicator light stays on for 1 to 3 seconds, or 2 seconds, and the foot sensor module 121 is controlled to detect whether the human foot is in its detection area, and then proceed to step S7.

[0086] Step S7: The indicator light is off for 0.5 to 1.5 seconds, or 1 second, and the light sensor module 122 is controlled to detect the intensity of the ambient light, then proceed to step S8;

[0087] Step S8: The indicator light, foot sensor module 121 and light sensor module 122 do not work for 2 to 5 seconds, which can be 3 seconds, then proceed to step S9;

[0088] Step S9: Determine whether the intensity of the ambient light detected by the light sensor module 122 is greater than or equal to the preset intensity. If yes, proceed to step S2; otherwise, proceed to step S6.

[0089] Indicator light 1213 periodically alternates between on and off. When indicator light 1213 is on, it controls foot sensor module 121 to simultaneously detect whether a person's foot is within its detection area. When indicator light 1213 is off, it controls light sensor module 122 to detect the intensity of ambient light, preventing the light emitted by indicator light 1213 from interfering with the light sensor module 122's acquisition of ambient light. Furthermore, if the intensity of ambient light detected by light sensor module 122 is less than a preset intensity 1800 times or more, it can be confirmed that it is late at night. At this point, the on-time of indicator light 1213 can be shortened, increasing the idle time of indicator light 1213, foot sensor module 121, and light sensor module 122, thus reducing the overall operating time of these components and saving energy. When light sensor module 122 detects ambient light intensity greater than or equal to the preset intensity again, it confirms that it is daytime, and the sensing device 1 returns to its initial normal operating state.
