[0025] An automatic induction ventilation device for a bathroom, such as Figure 1 As shown, it includes a sensor 1, a controller 15, a control switch 2 and a ventilation terminal.

[0026] Ventilation terminal such as Figure 3As shown, it includes a ventilation fan 4, a mounting structure, a filter 5, and a fly-killing structure. The mounting structure includes a fixed tube 3 and a mounting frame 7. The fixed tube 3 is a square tube embedded in the wall 16. The mounting frame 7 is a square frame structure and is fixed to the front end of the fixed tube 3. At the same time, the rear side wall is in contact with the wall. The rear side wall of the mounting frame 7 has a circular notch reserved, and an embedding groove is formed around the circular notch on the front side. The inner wall of the mounting frame has a mounting groove formed along the circumference, and a mounting notch 6 is reserved on the left side wall (or right side wall, depending on the specific situation). The ventilation fan 4 is sleeved in the circular notch, and a rib ring is formed along the circumference of the front side. The rib ring is sleeved and screwed into the embedding groove. The filter 5 has a square support frame that is compatible with the mounting notch 6. The filter 5 passes through the mounting notch 6 and is plugged into the mounting groove.

[0027] Fly killing structure Figure 5 As shown, it includes a purple light fly killer lamp 9, a lampshade 8, a sundries box 12 and a sunshade 10; the lampshade 8 is a square frame structure and is fixed to the front side wall of the mounting frame 7 (the specific shape of the lampshade 8 is as shown in FIG. Figure 5 As shown), a pair of hooks 11 are formed on the front side of the bottom of the two side frames of the lampshade 8, and the hooks 11 are mirrored on the left and right sides. The purple light fly killer 9 is fixed at the top inside the lampshade 8, and the purple light fly killer 9 is an electric shock fly killer. The sunshade 10 is a dark translucent plate (not blue-purple), which is arranged corresponding to the purple light fly killer 9 and is fixed to the top of the front side of the lampshade 8 to prevent the light of the purple light fly killer 9 from directly irradiating human skin. The debris box 12 is a box structure with an open top and is arranged at the bottom of the lampshade 8. A pair of hanging rings 13 are formed on the top of the rear side wall of the debris box 12, and the two hanging rings 13 are arranged corresponding to the two hooks 11. After the two hanging rings 13 are respectively matched with the two hooks 11, the debris box 12 is hung directly below the purple light fly killer 9 (when hanging, the rear side wall of the debris box 12 conflicts with the lampshade 8).

[0028] Sensor 1, controller 15, control switch 2; controller 15 is fixed on wall 16 and is respectively connected to sensor 1, control switch 2 and ventilation fan 4 lines, and a wiring tube 14 is provided outside the line to protect the line (part of the wiring tube 14 is embedded in or passes through the wall 16). Sensor 1 is an active motion sensor, and sensor 1 is arranged at the entrance and fixed on wall 16. When an object moves at the entrance, sensor 1 will generate induction and transmit the signal to controller 15 through the line to control the start and stop of ventilation fan 4. Control switch 2 is fixed on wall 16, and the automatic sensing ventilation device of the bathroom can be adjusted to automatic mode and manual mode through control switch 2, and the start and stop of ventilation fan 4 and purple light fly killer lamp 9 can be controlled in manual mode.

[0029] The sensor 1, controller 15, ventilation fan 4, and ultraviolet light fly killer 9, as well as their methods of use, are all well-known, established technologies. In a specific embodiment, the sensor 1 can be an active motion sensor, such as an infrared sensor or a microwave sensor. Active motion sensors, also known as radar-based motion sensors, have both a transmitter and a receiver, detecting motion by measuring changes in the amount of sound or radiation reflected back to the receiver. Active motion sensors emit radio waves / microwaves. When an object moves within the area controlled by the motion sensor, the sensor looks for changes in the Doppler (frequency) of the waves. When these changes return to the sensor detector, they indicate that the waves have struck the moving object. The motion sensor interprets these changes and sends an electrical signal to an alarm system, a light, or other device connected to the motion sensor. Once the sensor detects a person, the controller activates the ventilation fan. All of the above sensors are readily available and the control circuitry is also conventional.

[0030] In the specific implementation of this embodiment:

[0031] By controlling the switch 2, the present invention is switched to the automatic mode, and the response time of the ventilation fan 4 (automatically starts after receiving the signal from the sensor 1 for 0s, 5s or 10s), the stop response time (automatically stops after receiving the signal from the sensor 1 for 15s, 45s or 5min), the continuous working time (automatically starts for 10min, automatically stops after 15min), and the fly killing time period of the purple light fly killer 9 (the purple light fly killer 9 is timed to turn on and off, and multiple fly killing time periods can be set within a day) are set.

[0032] When someone enters the bathroom to use the toilet, they will be captured by the active motion sensor when passing through the entrance, generating an induction, and transmitting a signal to the controller 15 through the line. The controller 15 controls the ventilation fan 4 to start and ventilate and exhaust, thereby reducing the odor in the bathroom. The ventilation fan 4 will be automatically stopped after a certain period of time or after leaving the toilet to reduce energy consumption.

[0033] The purple light fly killer lamp 9 is turned on and off regularly according to the set fly killing period, and the flies and insects in the bathroom will be attracted by the purple light and killed by the purple light fly killer lamp 9 with electric shock, and the fly corpses will fall into the debris box 12 to prevent pollution of the ground hygiene. By killing flies regularly, the number of flies and insects in the bathroom can be effectively reduced, and people can be prevented from being harassed, attached and bitten by a large number of flies and insects when using the toilet, and the spread of bacteria can be reduced. At the same time, the waste and consumption of electricity caused by long-term opening can be reduced. When the purple light fly killer lamp 9 is working, its light is blocked and filtered by the sunshade 10 to prevent a large amount of purple light from directly irradiating human skin and eyes and causing damage. It is worth mentioning that the debris box 12 needs to be cleaned regularly to dump the accumulated fly corpses (which can be used for farmed poultry, wild birds or fish).

[0034] According to needs, the present invention can be adjusted to manual mode to start the ventilation fan 4 or the purple light fly killer lamp 9 for a long time to improve the ventilation and fly killing effects.

[0035] After long-term use, the filter 5 should be replaced to prevent the filter 5 from being blocked and reducing the ventilation efficiency.

[0036] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
