Toilet leak warning device

The present invention relates to a warning device, and more particularly to a toilet leakage warning device applied to a toilet.

The toilet is a sanitary device that must be provided in the existing home. However, if the inlet valve or the drain valve of the toilet fails, the water tank may leak. If the user does not immediately find and repair it, it will often cause a long time. A large amount of water leakage leads to great waste of water resources. At present, there are many detection devices for detecting leakage of toilets on the market. Therefore, the purpose of the present invention is to provide a novel structure leakage warning device for users to choose to purchase or use. .

Therefore, the purpose of the present invention is to provide a toilet water leakage warning device which is novel in structure and easy to find a leak in a toilet.

Therefore, the novel toilet leakage warning device comprises a sound detecting unit and a warning unit. The sound detecting unit can be triggered by the flushing sound to start timing a hydration time, and at the end of the hydrating time, detect whether there is a running water sound, and when detecting the running water sound, send a water leakage signal. The warning unit signal is connected to the sound detecting unit, and can send a warning message when receiving the water leakage signal.

The effect of the novel is that through the design of the sound detecting unit and the warning unit, the sound emitted by the toilet can be detected and analyzed to instantly remind the user whether the toilet is leaking.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , an embodiment of the toilet leakage warning device of the present invention is suitable for being installed on a water tank 900 of a toilet (not shown) and including a casing 1 and a sound detecting unit. 2, and a warning unit 3.

The housing 1 includes a base 11 and a cover 12 overlying the base 11. The base 11 can be placed on the water tank 900 of the toilet and has a base wall 111, an upper surrounding wall 112 extending upward from the base wall 111, and a lower surrounding extending downwardly from the base wall 111. Wall 113. The base wall 111 and the upper surrounding wall 112 surround an interior space 13 that defines an opening upward. The base wall 111 and the lower surrounding wall 113 surround a sound collecting space 14 that defines an opening downward. The lower surrounding wall 113 has two first side wall portions 114 extending downward from the front and rear sides of the base wall 111, and two of the opposite sides of the left and right sides of the base wall 111 are curved downwardly and outwardly and then extended downward. An extended second side wall portion 115. The first side wall portion 114 cooperates with the second side wall portion 115 to make the sound collecting space 14 have a narrow upper and lower width chamber for collecting sound. The cover 12 can be assembled corresponding to the top edge of the upper surrounding wall 112 to close the interior space 13. The internal space 13 can accommodate the sound detecting unit 2 and the warning unit 3.

The sound detecting unit 2 includes a sound collecting module 21, a flush detecting module 22, a timing module 23, and a water detecting module 24. The sound collecting module 21 is disposed on the base wall 111, and can pick up the sound of the sound collecting space, perform processing such as amplification processing filtering, and convert and output an audio signal.

The flush detection module 22 can compare the sound signal, and triggers the timing module 23 when the sound signal corresponds to a flush sound. In practice, the flush detection module 22 can determine whether the sound signal corresponds to the flushing sound through the amplitude, frequency or waveform of the sound signal. For example, if the amplitude of the sound signal is high and the frequency is high, the water detecting signal can be judged. The sound signal corresponds to a flushing sound, but the implementation is not limited thereto.

When the timing module 23 is triggered to start, a timing of hydration is started, and when the timing of the hydration time ends, the flow detection module 24 is triggered to be activated. The hydration time can be set to the time required for the toilet to re-storage after flushing, for example, 30 seconds, but in practice, it is designed according to the amount of water stored in the toilet tank 900 to improve the detection sensitivity of the present invention.

When the water detecting module 24 is triggered to start, the sound signal can be compared, and when the sound signal corresponds to a flowing water sound, a water leakage signal is sent. In practice, the flow detection module 24 can determine whether the sound signal corresponds to the flowing sound through the amplitude, frequency or waveform of the sound signal. For example, if the amplitude of the sound signal is low and the frequency is low, the sound can be judged. The signal corresponds to the running water sound, but the implementation is not limited to this.

The warning unit 3 is connected to the sound detecting unit 2, and includes a control module 31 and a sounding module 32. The control module 31 can drive the sounding module 32 to send the warning message as a warning sound when receiving the water leakage signal. The sounding module 32 can be a buzzer or an electronic component that can emit a built-in voice. For example, a voice such as "pay attention to water leakage" can be issued, but not limited to the above.

Referring to FIG. 2, FIG. 3 and FIG. 4, the toilet leak warning device of the present invention can be smoothly placed on the water tank 900 of the toilet through the shape design of the casing 1, and the sound collecting space is closed with the water tank 900. 14. The toilet leakage warning device can be powered by a battery 700 (see FIG. 1), and after the power is turned on, the sound of the water tank 900 is continuously picked up. When the user finishes using the toilet, the sound is detected. The measuring unit 2 is triggered by the flushing sound emitted by the toilet, and starts to count the hydrating time. During the hydrating time, the water tank 900 of the toilet will store water, and the running water sound continuously, when the hydrating time ends. The sound detecting unit 2 analyzes the sound signal to detect whether the toilet still emits a sound of running water.

If the sound detecting unit 2 detects the running water sound, the warning unit 3 will send out the warning message to remind the user that the toilet may be leaking water, and the water tank 900 continuously hydrates, thereby continuously emitting a running water sound. Since the user will leave after using the toilet at home, it is difficult to detect the sound of running water, and the warning message sent by the warning unit 3 can obviously remind the user that the toilet is abnormal, so that the user can go to the maintenance immediately. In addition, if the water tank 900 is too slow to replenish water, the present invention will also issue a warning message to remind the user to perform maintenance, so it is not limited to the above abnormal conditions.

In summary, the novel toilet leakage warning device can detect and analyze the sound emitted by the toilet through the sound detecting unit 2 and the design of the warning unit 3, and promptly remind the user when the sound is abnormal. In order to facilitate the user to go to the processing or maintenance, the shape design of the base 11 can also enhance the sound collection effect of the sound detecting unit 2, so that the purpose of the present invention can be achieved.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
