[0002] With the improvement of living standards, people are paying more and more attention to interior decoration and renovation, especially waterproofing in the bathroom. In the current process, waterproofing is required for the bathroom settling tank before backfilling and tiling. After waterproofing, a water retention test is required 1-2 days later. Workers visually observe the water level in the bathroom for 48 hours and judge the drop in water level based on experience to determine whether leakage has occurred. The test method is relatively cumbersome and cannot quickly and accurately determine whether the bathroom is leaking. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a bathroom waterproof detection label, which includes a label body and a water level detection module located inside the label body. The water level detection module includes a first switch tube and a water level probe for detecting the water level.

The output pin of the timer is connected to the control terminal of the second switch. The input terminal of the second switch is connected to the power supply, and its output terminal is connected to the input terminal of the first switch. The water level probe is connected to the control terminal of the first switch through a first resistor. The output terminal of the first switch is also grounded through a capacitor.

[0014] Figure 2 This is a circuit diagram of the water level detection module in the bathroom waterproof testing label of this utility model. Detailed Implementation

[0015] To enable those skilled in the art to more clearly understand the purpose, technical solution and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0016] Reference Figures 1 to 2 , Figures 1 to 2A specific embodiment of the bathroom waterproofing test label of this utility model is shown. In the embodiment shown in the accompanying drawings, the bathroom waterproofing test label includes a label body 10 and a water level detection module 20 located within the label body 10. The water level detection module 20 includes a first switch tube Q1 and a water level probe L for detecting the water level. The water level probe L is located within the label body 10 with one end exposed on the outer surface of the label body 10. The water level probe L is connected to the control terminal of the first switch tube Q1. The input terminal of the first switch tube Q1 is connected to a power source, and its output terminal is connected to an external control terminal. When the detected water level is lower than a preset water level, the first switch tube Q1 is turned on, sending a signal SW to the external control terminal. Understandably, the external control terminal can be a mobile phone, tablet, or computer, etc. A battery is provided within the label body 10 as a power source. When the water level probe L is exposed within the label body 10, a sealing ring can also be provided between the water level probe L and the label body 10 to prevent water from the bathroom from entering the label body 10 during testing. Based on the above design, when the bathroom waterproofing test label of this utility model is used, the current water level in the bathroom can be detected by the water level probe L. During the 48-hour water storage and tightness test in the bathroom, when the current water level detected by the water level probe L is lower than the preset water level, that is, when the water level drops beyond the preset distance threshold, the first switch tube Q1 is turned on and a signal SW is sent to the external control terminal for prompting, so that the user can know the waterproofing effect of the bathroom in a timely manner without going to the site.

[0017] In some embodiments, the water level detection module 20 further includes a timer U1 and a second switch Q2. In this embodiment, the timer U1 can be an NE555. The output pin (pin 3) of the timer U1 is connected to the control terminal of the second switch Q2. The input terminal of the second switch Q2 is connected to the power supply V+, and its output terminal is connected to the input terminal of the first switch Q1. The water level probe L is connected to the control terminal of the first switch Q1 through a first resistor R1. The output terminal of the first switch Q1 is also grounded through a capacitor C1. A second resistor R2 is connected in parallel across the two ends of the capacitor C1. Based on the above design, the water level detection module 20 in this embodiment is a pulse-type water level detection module, which provides more accurate detection. Timer U1 acts as a pulse transmitting unit, sending pulses to the second switch Q2 at regular intervals during the 48-hour water tightness test. For example, it can send a pulse of 100ms per second to the second switch Q2. After power amplification by the second switch Q2, the output of the second switch Q2 is sent to the input of Q1. The water level probe L sends the water level signal to the control terminal of Q1 through a 1K resistor. The common terminal probe is connected to the negative terminal of the power supply. When there is a pulse, Q1 detects effectively. When timer U1 does not send a pulse signal to Q1, the water level probe L does not form a circuit with the water. Therefore, the probe will not undergo electrolytic reaction in the water, so that scale will not form on the contact surface between the water level probe L and the water, thus preventing detection failure and making the detection more accurate.

[0018] Preferably, in this embodiment, the first switch Q1 is a PNP transistor, which is turned on at a low level. The collector, emitter, and base of the PNP transistor serve as the output, input, and control terminals of the first switch Q1, respectively. The second switch Q2 is an NPN transistor, and the collector, emitter, and base of the NPN transistor serve as the input, output, and control terminals of the second switch Q2, respectively.

[0019] Furthermore, in some embodiments, the water level detection module 20 further includes a third switch Q3. The output terminal of the first switch Q1 is connected to the control terminal of the third switch Q3, the input terminal of the third switch Q3 is connected to the power supply V+, and its output terminal is grounded through the capacitor C1 and connected to an external control terminal to send the detected water level information to the external control terminal. Specifically, the third switch Q3 can be an NPN transistor, with its collector, emitter, and base serving as the input, output, and control terminals, respectively. Based on the above design, the third switch Q3 and capacitor C1 can maintain the water level signal.

[0020] In some embodiments, the back of the label body 10 may also be provided with an adhesive layer so that it can be pasted onto a wall during use, and the surface of the label body 10 is also provided with scale lines 30, so that the water level drop can be visually observed through the scale lines 30 during use, such as... Figure 1 As shown, the water level probe L can be located in the middle of the label body 10, approximately at the 3cm scale line. When in use, the 5cm scale line can be aligned with the water surface. When the water level drops by more than 2cm within 48 hours, the first switch tube Q1 is turned on to alert the user.

[0021] In summary, this utility model's bathroom waterproofing test label is equipped with a water level detection module. When conducting a water tightness test after waterproofing is completed in the bathroom, this utility model's bathroom waterproofing test label can be fixed to the wall, and its top can be flush with the water surface. If the water level probe in the water level detection module detects that the water level in the bathroom is lower than the preset water level, that is, when the water level drops beyond the preset distance threshold, the first switch tube is turned on and sends a signal to the external control terminal, indicating that leakage has occurred in the bathroom. This allows users to quickly and accurately know the waterproofing effect of the bathroom without having to go to the site to judge based on experience, thus improving testing efficiency.
