[0002] Some existing toilets use ultraviolet rays to sterilize the toilet bowl. In one toilet in the related art, an ultraviolet lamp bead is embedded in the top of the toilet spray rod. After the toilet spray rod is extended into the toilet bowl space, the ultraviolet lamp bead can irradiate the toilet bowl below it, but the direct irradiation range of the ultraviolet lamp bead is limited, and it is difficult to cover all corners and gaps of the toilet bowl. Specifically, it is difficult to cover the upper half of the toilet bowl, and only local sterilization can be achieved. Another toilet in the related art embeds six to eight ultraviolet lamp beads at the bottom of the toilet ring and arranges them in sequence around the toilet ring. When these ultraviolet lamp beads are turned on at the same time, they can completely cover all corners of the toilet bowl. However, due to the large number of ultraviolet lamp beads used, its production cost is relatively high. Summary of the invention

DETAILED DESCRIPTION

[0056] The present application describes multiple embodiments, but the description is exemplary rather than restrictive, and it is obvious to those skilled in the art that there may be more embodiments and implementations within the scope of the embodiments described in the present application. Although many possible feature combinations are shown in the drawings and discussed in the specific embodiments, many other combinations of the disclosed features are also possible. Unless specifically limited, any feature or element of any embodiment may be used in combination with any other feature or element in any other embodiment, or may replace any other feature or element in any other embodiment.

[0057] like Figure 1 , 2 As stated, Figure 1 , 2 A toilet 100 in an embodiment of the present application is shown. The toilet 100 is a smart toilet. The toilet 100 includes a toilet cover assembly 2 and a toilet body 1. The toilet cover assembly 2 is arranged on the top of the toilet body 1.

[0058] The toilet body 1 can be made of ceramic material. The toilet body 1 is the main part of the toilet 100. A pot surface space 11 is provided in the toilet body 1. The pot surface space 11 is a cavity for accommodating excrement. An excrement inlet 12 is provided at the top of the pot surface space 11, and a sewage outlet 13 is provided at the bottom of the pot surface space 11.

[0059] The toilet cover assembly 2 includes a bottom shell 21 and two sterilization modules 22. The bottom shell 21 can be constructed as a box-shaped structure or a square plate-shaped structure. The bottom shell 21 is installed on the top of the toilet body 1 of the toilet 100 and is located at the upper rear of the pot surface space 11 of the toilet body 1. The bottom shell 21 is located behind the excrement inlet 12 of the pot surface space 11. The bottom shell 21 includes a front end close to the pot surface space and a rear end opposite to the front end. The front end of the bottom shell 21 refers to an end of the bottom shell 21 close to the excrement inlet 12 of the pot surface space 11. The two sterilization modules 22 are both arranged at the front end of the bottom shell 21, and the two sterilization modules 22 are spaced apart on the left and right sides of the front end. The two sterilization modules 22 can be respectively arranged on both sides of the center of the front end of the bottom shell 21. Each sterilization module 22 includes an ultraviolet lamp bead 221. The ultraviolet lamp bead 221 can emit ultraviolet light beams. The ultraviolet light emitted by the ultraviolet lamp bead 221 can be ultraviolet light in the UVC band. The ultraviolet lamp beads 221 of the two sterilization modules 22 are configured to emit ultraviolet light beams toward the front and lower part of the bottom shell 21 to jointly cover and irradiate all inner walls of the pot surface space 11, and the inner wall of the pot surface space 11 is the toilet pot surface. The two ultraviolet lamp beads 221 can be respectively located at the rear of the excrement inlet 12, and are respectively located at both sides of the rear of the excrement inlet 12. The two ultraviolet lamp beads 221 both emit ultraviolet light beams toward the front and lower direction of the excrement inlet 12, and the two ultraviolet light beams directly irradiate the toilet pot surface, and all parts of the toilet pot surface can be irradiated by the ultraviolet light beams.

[0060] like Figure 3 , 4 As shown, two ultraviolet lamp beads 221 arranged at intervals both emit ultraviolet light beams from the front end of the shell toward the front and lower part of the bottom shell 21. These two ultraviolet light beams can irradiate all the inner walls of the pot surface space 11 from the rear of the top of the pot surface space 11 of the toilet 100. All corners and gaps in the pot surface space 11 of the toilet can be covered by ultraviolet rays. Since ultraviolet rays can destroy the molecular structure of microbial cells, microorganisms on the inner walls of the pot surface space 11 can be killed. At the same time, only two ultraviolet lamp beads 221 need to be set in this technical solution, and the production cost of the toilet cover assembly 2 is low. The two sterilization modules 22 are set on the bottom shell 21 for easy installation. At the same time, the two sterilization modules 22 are installed at the lower front end of the bottom shell 21, so that it is not easy for the user to observe the existence of the sterilization modules 22, and the toilet is neat and beautiful as a whole.

[0061] In an illustrative embodiment, Figures 5 to 8 As shown, the ultraviolet light beams emitted by the two ultraviolet lamp beads 221 are divergent light beams. The ultraviolet light in the ultraviolet light beam is distributed radially, and the farther away from the ultraviolet lamp bead 221, the larger the cross-sectional area of ​​the ultraviolet light beam.

[0062] The angle b between the optical axis of the ultraviolet light beam emitted by the two ultraviolet lamp beads 221 and the horizontal direction is 40° to 50°, preferably 45°. The divergence angle a of the ultraviolet light beam emitted by the two ultraviolet lamp beads 221 is 110° to 130°, preferably 120°. The optical axis of the ultraviolet light beam refers to the central axis of the ultraviolet light beam, and the ultraviolet light in the ultraviolet light beam is roughly symmetrically distributed around this central axis.

[0063] In this way, when the angle b between the optical axes of the ultraviolet light beams emitted by the two ultraviolet lamp beads 221 and the horizontal direction is 40°~50°, and the divergence angle a of the ultraviolet light beams emitted by the two ultraviolet lamp beads 221 is 110°~130°, the ultraviolet light beams emitted by the two ultraviolet lamp beads 221 can completely cover the toilet pot surface and can disinfect all parts of the toilet pot surface.

[0064] In an illustrative embodiment, Fig. 9 As shown, the toilet cover assembly 2 also includes a toilet cover 23, a toilet ring 24, a control assembly and a human body detection assembly. The control assembly is electrically connected to the ultraviolet lamp bead 221 through an electric wire. The toilet cover 23 and the toilet ring 24 are both rotatably connected to the bottom shell 21. The toilet ring 24 is configured in a ring or U shape and is used to support the human body. The toilet cover 23 is arranged on the side of the toilet ring 24 facing away from the bottom shell 21. The toilet cover 23 can cover the toilet ring 24.

[0065] In this embodiment, if Fig. 9As shown, the control component includes a control board and a constant current protection board. The control board is a logic control unit of the toilet 100. The control board can be a single-chip microcomputer or a microcomputer. The constant current protection board is electrically connected to the control board and the ultraviolet lamp beads 221 of the two sterilization modules 22. The constant current protection board is used to provide a stable driving current to the two ultraviolet lamp beads 221 at the same time to drive the two ultraviolet lamp beads 221 to work at the same time. The constant current protection board is used to output a stable driving current to drive the ultraviolet lamp beads 221 to work, which can avoid the ultraviolet lamp beads 221 from flickering. At the same time, it can also provide overcurrent protection and overvoltage protection for the ultraviolet lamp beads 221 to avoid damage to the ultraviolet lamp beads 221. The control board can provide input current to the constant current protection board, and control the opening and closing of the ultraviolet lamp beads 221 by controlling the presence or absence of input current of the constant current protection board. That is, the control board transmits current to the constant current protection board, and the constant current protection board transmits a stable driving current to the ultraviolet lamp bead 221 to turn on the ultraviolet lamp bead 221; the control board stops transmitting current to the constant current protection board, and the constant current protection board stops transmitting a stable driving current to the ultraviolet lamp bead 221 to turn off the ultraviolet lamp bead 221. The control board can be configured to periodically control the two ultraviolet lamp beads 221 to work simultaneously for a preset time. For example, the control board can turn on the ultraviolet lamp bead 221 every 1 to 3 hours, and the working time of the ultraviolet lamp bead 221 after each turning on can be 5 to 30 minutes to sterilize the pot surface space 11. The control board can also be configured to control the two ultraviolet lamp beads 221 to work simultaneously for a preset time after each closing of the toilet lid 23.

[0066] The human body detection component is electrically connected to the control panel of the control component. The human body detection component is used to detect whether there is a human body around the toilet 100. For example, when a user goes to the toilet and approaches the toilet 100, the human body detection component can detect the approach of a human body. The human body detection component includes a microwave radar, a foot sensing device and / or an infrared sensing device. The microwave radar can emit microwave signals and receive reflected microwave signals, and analyze the frequency changes of the signals based on the Doppler effect to detect a moving human body. A moving human body can be accurately detected and tracked. The foot sensing device can be an infrared sensing switch or a laser position switch that can sense the human foot.

[0067] The control panel of the control component is configured to turn off all the ultraviolet lamp beads 221 based on the human body detection component detecting the presence of a human body around the toilet 100 .

[0068] In this way, when the human body detection component detects the presence of a human body around the toilet 100, the detection result is sent to the control board, and the control board stops transmitting current to the constant current protection board, and then the constant current protection board stops transmitting driving current to the ultraviolet lamp beads 221, and both ultraviolet lamp beads 221 are turned off. In this way, the human body can be prevented from being irradiated by ultraviolet rays and from being damaged.

[0069] In an illustrative embodiment, Fig. 9 As shown, the toilet lid assembly 2 also includes a lid opening detection assembly. The lid opening detection assembly can be a photoelectric sensor, a Hall sensor or an encoder. The lid opening detection assembly is electrically connected to the control board of the control assembly. The lid opening detection assembly is used to detect whether the toilet lid 23 is in a closed state and send the detection result to the control board. The closed state of the toilet lid 23 refers to the state in which the toilet lid 23 is covered on the toilet ring 24.

[0070] The control component is configured to turn off all the ultraviolet lamp beads 221 based on the lid opening detection component detecting that the toilet lid 23 is not in a closed state.

[0071] In this way, when the lid opening detection component detects that the toilet lid 23 is not in the closed state, it sends the detection result to the control board, and the control board stops transmitting current to the constant current protection board, and then the constant current protection board stops transmitting driving current to the ultraviolet lamp beads 221, and both ultraviolet lamp beads 221 are turned off. In this way, it can further prevent the human body from being irradiated by ultraviolet rays and avoid human body damage, and prevent ultraviolet rays from leaking into the surrounding environment to accelerate the aging of objects in the surrounding environment.

[0072] In an illustrative embodiment, the toilet cover assembly 2 further includes a gearbox (not shown in the figure) and a motor (not shown in the figure). The gearbox is a reducer. The gearbox is provided with an input shaft and an output shaft. The input shaft of the gearbox is drivingly connected to the main shaft of the motor. The input shaft of the gearbox and the main shaft of the motor may be directly connected. The output shaft of the gearbox is drivingly connected to the toilet cover 23. The output shaft of the gearbox may be directly connected to the rotating shaft of the toilet cover 23. The gearbox is used to reduce the torque output by the motor and increase the torque, and then transmit it to the toilet cover 23 to drive the toilet cover 23 to rotate. The motor can drive the toilet cover 23 to rotate so that the toilet cover 23 swings back and forth between the closed state and the open state. The motor is electrically connected to the main control board, and the rotation of the motor is controlled by the main control board.

[0073] The cover opening detection component is an encoder, and the cover opening detection component is arranged on the gear box. If the rotation angle of the gear in the gear box measured by the cover opening detection component does not reach the closing angle, it is determined that the toilet cover 23 is not in a closed state. The gear can be any gear in the gear box, and the gear is preferably a gear sleeved on the output shaft of the gear box. The closing angle is the rotation angle of the gear when the toilet cover 23 is in a closed state.

[0074] The toilet 100 uses an encoder to measure the rotation angle of the gear to determine the opening and closing of the toilet cover 23, which is accurate and low-cost.

[0075] In an illustrative embodiment, Fig. 9As shown, the control assembly also includes a micro switch. The micro switch is arranged on the circuit connecting the constant current protection board and the control board, and the constant current protection board is electrically connected to the control board through the micro switch. The micro switch is a normally open switch, and the electrical connection between the constant current protection board and the control board is disconnected when the micro switch is not triggered. The micro switch can be arranged on the bottom shell 21, and the toilet cover 23 triggers the micro switch when the toilet cover 23 is in a closed state.

[0076] The micro switch is triggered by the toilet cover 23 when the toilet cover 23 is in the closed state, and the micro switch is in the closed state, thereby connecting the constant current protection board and the control board. The micro switch is not triggered when the toilet cover 23 is not in the closed state, and the micro switch is in the open circuit state, disconnecting the electrical connection between the constant current protection board and the control board.

[0077] When the toilet lid 23 is not in the closed state, the micro switch disconnects the line between the control board and the constant current protection board, and the control board no longer supplies power to the constant current protection board, and then the constant current protection board stops supplying driving current to the ultraviolet lamp beads 221, and both ultraviolet lamp beads 221 are turned off. In this way, the human body can be further protected from ultraviolet radiation and damage, and ultraviolet rays can be prevented from leaking into the surrounding environment to accelerate the aging of objects in the surrounding environment.

[0078] In an illustrative embodiment, Figure 6 , 8 As shown, the front end of the bottom shell 21 is provided with two mounting holes 211. The mounting holes 211 are through holes. The mounting holes 211 extend from top to bottom, and the end facing the mounting holes 211 is closer to the front of the bottom shell 21 than the end facing upwards. The mounting holes 211 are separated from each other. The two sterilization modules 22 are respectively installed in the two mounting holes 211.

[0079] The two sterilization modules 22 are respectively installed in the two installation holes 211 of the bottom shell 21. This assembly method is firm and simple.

[0080] In an illustrative embodiment, Fig.10 , 11 As shown, the sterilization module 22 also includes a housing 222, a transparent plate 224 and a circuit board 223. The housing 222 includes a barrel 2221. The cross section of the barrel 2221 is the same as the cross section of the mounting hole 211. The cross sections of the barrel 2221 and the mounting hole 211 can both be set to a rectangular shape. The barrels 2221 of the two sterilization modules 22 are respectively inserted into the two mounting holes 211. The barrel 2221 is provided with a light outlet 2222 at the downward end, and a mounting port at the upward end. The light outlet 2222 can be set to a square shape.

[0081] The transparent plate 224 may be a quartz glass plate. The transparent plate 224 may be rectangular. The transparent plate 224 is disposed in the barrel 2221 and covers the light outlet 2222 of the barrel 2221. The transparent plate 224 may be bonded to the barrel 2221.

[0082] The circuit board 223 is disposed in the barrel 2221. The circuit board 223 may be a rectangular plate. One surface of the circuit board 223 faces the light outlet 2222 of the barrel 2221, and the other surface of the circuit board 223 faces the mounting opening of the barrel 2221. The ultraviolet lamp bead 221 is welded on the surface of the circuit board 223 facing the light outlet 2222.

[0083] In this way, the transparent plate 224 and the circuit board 223 can be installed into the cylinder 2221 from the installation port of the cylinder 2221, and the ultraviolet light emitted by the ultraviolet lamp bead 221 can be emitted from the shell 222 through the light outlet 222. At the same time, the shell 222 and the transparent plate 224 can protect the ultraviolet lamp bead 221 and the circuit board 223 to prevent water and dust from contaminating the ultraviolet lamp bead 221.

[0084] In an illustrative embodiment, Fig.10 As shown, a night light 225 is also provided on the circuit board 223 of at least one sterilization module 22. The night light is provided on the board surface of the circuit board 223 facing the light outlet 2222 of the cylinder 2221. The night light 225 can be an LED light. The night light 225 is electrically connected to the control board and is directly powered by the control board. The light emitted by the night light 225 is irradiated from the light outlet 2222 to the pot surface space 11 of the toilet 100, which can facilitate the user to check the position of the toilet 100 when going to the toilet at night.

[0085] In an illustrative embodiment, the housing 222 further includes a connecting portion 2223. The connecting portion 2223 is disposed on the outer wall of the cylinder 2221. The connecting portion 2223 may be a protrusion protruding from the outer wall of the cylinder 2221. The connecting portion 2223 is connected to the bottom shell 21. The connecting portion 2223 and the bottom shell 21 may be connected by screws.

[0086] The sterilization module 22 is tightly connected to the bottom shell 21 via the connection portion 2223 , which can prevent the sterilization module 22 from escaping from the mounting hole 211 of the bottom shell 21 .
