Suction cup adsorption force warning sensing structure

This creation department is concerned with a "sucking disc adsorption force early warning sensing structure", especially one that can instantly monitor the adsorption pressure state of the suction cup adsorption surface and use the differential pressure sensing change to automatically generate the warning effect.

According to the general suction cup after adsorption for a period of time, or because the area of the adsorption surface is insufficient and the suction cup is not attached, the outside air often has the opportunity to enter the suction cup, so that the suction cup changes from negative pressure to positive pressure and causes suction of the suction cup. The power is gradually lost, and the general user cannot observe the abnormality of looseness or suction reduction from the outside of the suction cup. The suction cup is often detached from the adsorption plane by the user without warning, and the hanging object falls. It is not ideal for the occurrence of the situation and the inconvenience and insecurity of use.

The detection area (13A) is transmitted to the control circuit board (121) to calculate the conversion signal response or display, and when the closed air chamber detection area (13A) is exposed to the vacuum value or the negative pressure difference of the air reaches the preset warning pressure value. The control circuit board (121) activates the warning component (122) to send a signal, so that the user can predict the suction cup at the first time. (10) It is in the process of weakening suction, so as to make up the vacuum negative suction in the suction cup (10) at any time to effectively prevent the falling off during use, thereby achieving safer, more practical and real-time monitoring and detection. The pressure state and the use of differential pressure sensing changes can automatically generate an early warning sucker.

The sealed receiving portion (13) as described above may be directly disposed in the body of the suction cup (10) or connected to an external receiving portion (not shown) outside the suction cup (10) to form a sealed portion. The closed air chamber detecting area, wherein the pressure sensor (12) can be directly connected to the sealed receiving portion (13) of the body of the suction cup (10) for connection sensing or externally connected to the outside. The inner portion of the accommodating portion is connected to sense, and the warning element (122) can be set as an audible and visual alarm for an LED light source, a voice or a music ringtone, and the like.

The pressure sensor (12) connected to the control circuit board (121) in the sealed receiving portion (13) of the suction cup (10) as described above may be additionally connected to an external digital display screen. Suction plate (10) differential pressure change value.

The control circuit board (121) in the closed receiving portion (13) of the suction cup (10) as described above may be connected to a wireless transceiver circuit and coupled to a remote receiving digital panel for transmission and receiving real-time monitoring. The control circuit board (121) enables the wireless transceiver circuit to receive the detected pressure value and transmit the wireless transceiver circuit to the remote digital panel to receive the signal to instantly display the pressure difference of the suction cup (10).

Wherein, the upper end of the suction cup (10) as described above can be set as a pull-type (as shown in the fourth figure) or a buckle-type (as shown in the fifth figure) for applying a vacuum (14), so that The urging portion (14) communicates with the sealed accommodating portion (13) and is provided with a through hole (131) in the sealed accommodating portion (13) so that the urging portion (14) can be pulled or pulled during the suction use. The suction surface (11) of the suction cup (10) can be formed by vacuuming. The air is adsorbed, and the adsorption surface (11) is pressed and sealed to form a closed air chamber detecting area (13A) and the pressure sensor (12) is connected through the sealed receiving portion (13).
