Description

Technical Field

[0001] The utility model relates to the technical field of sucker devices, in particular to a vacuum sucker pressure relief alarm device. Background Technique

[0002] At present, the known manual and electric sucker structures are composed of a rubber sucker, an air extraction device, and a sucker cover cloud platform. There is a cavity inside the sucker, and the sucker is evacuated to a vacuum through an air extraction device (manual air pump or electric motor air pump). The atmospheric pressure outside the sucker presses the sucker tightly on the surface of an object, and then a photography bracket, a vehicle-mounted luggage rack, a bicycle rack, etc. are assembled on the sucker cover cloud platform. Since no tools are required by the user after the sucker adsorbs, after manually picking at the edge of the sucker, the sucker can be depressurized and removed. After the sucker is depressurized, there is no alarm or warning function. When the user is not near the sucker, the items above the sucker cloud platform are easily stolen by others.

[0003] Therefore, improvements need to be made in this regard. Content of the Utility Model

[0019] As Figure 1As shown in the figure, a vacuum suction cup pressure relief alarm device is provided, including: a suction cup; an air extraction device, the air extraction device is connected to the suction cup through a trachea, and the air extraction device drives air extraction inside the suction cup to adsorb to an external object; a pressure sensor switch, the pressure sensor switch is connected to the trachea, the pressure sensor switch preset a pressure value, and when the pressure in the suction cup is lower than the preset pressure value, the circuit is connected; a wireless transmission module, the wireless transmission module is electrically connected to the pressure sensor switch, and the wireless transmission module is used to transmit a first message to a bound user; a battery, the battery is electrically connected to the pressure sensor switch and the wireless transmission module, and the battery is used to provide power.

[0020] In view of the technical problems recorded in the background art, a vacuum suction cup pressure relief alarm device is proposed. In the above, the suction cup is a rubber suction cup, which mainly forms a vacuum through air extraction and adsorbs on an external object. The air extraction device can be in the form of a manual air extraction pump or an electric motor air extraction pump. When a manual air extraction pump is used, it is a manual vacuum extraction method to adsorb the suction cup on the surface of an object; when an electric motor air extraction pump is used, it is a motor-driven vacuum extraction method to adsorb the suction cup on the surface of an object. In implementation, the suction cup is connected to the air extraction device through a trachea, and a pressure sensor switch is installed on the trachea. By presetting the pressure value of the pressure sensor switch, when the pressure value is lower than the set pressure value, the pressure sensor switch closes. A wireless transmission module is set to be electrically connected to the pressure sensor switch. The wireless transmission module can transmit a first signal, and the first signal can notify the user by means of telephone voice prompt, short message prompt, and WeChat official account, etc., and the user can view the position of the suction cup through the WeChat official account. The battery is used to provide power.

[0021] During use, the air extraction device extracts vacuum from the suction cup for adsorption. When there is negative pressure adsorption in the suction cup, the pressure sensor switch circuit is disconnected. When the suction cup is pressure relieved, the pressure sensor switch circuit is closed. After the wireless transmission module is powered on, it sends a first signal to notify the user by means of telephone voice prompt, short message prompt, and WeChat official account, etc., and the user can view the position of the suction cup through the WeChat official account.

[0022] Specifically, the first message includes one or more of sending a warning message, dialing the bound user's phone number, and sending a positioning message.

[0023] Specifically, it includes a GPS positioning module. The GPS positioning module is electrically connected to the battery, and the GPS positioning module is used to locate the position of the suction cup. Setting the GPS positioning module facilitates the user to obtain the position of the suction cup through the device and facilitates the user to retrieve the suction cup.

[0024] As shown in the reference figure, the utility model includes a buzzer, which is electrically connected to the pressure sensor switch and the battery respectively; the pressure sensor switch closes the circuit to drive the buzzer to give out a beeping warning.

[0025] In another implementable technical solution, by adding a buzzer which is connected in series with the pressure sensor switch, when there is negative pressure adsorption in the suction cup, the pressure sensor switch circuit is disconnected; when the suction cup is depressurized, the pressure sensor switch circuit is closed, and the active buzzer is powered on to give out intermittent beeping sounds to give a warning.

[0026] Specifically, it includes a check valve which is arranged between the air extraction device and the air pipe. The check valve set is convenient for the air extraction device to evacuate the suction cup, and on the other hand, it effectively avoids the pressure relief from the air extraction device end, resulting in false alarm situations.

[0027] Furthermore, it includes a power switch which is electrically connected to the battery and the pressure sensor switch, and the power switch is used to close the circuit.

[0028] After the buzzer is triggered to work, by setting a power switch in the circuit, after the user closes the power switch with a key, the suction cup will not give out an alarm and wireless signal after depressurization.

[0029] The above does not impose any limitation on the technical scope of the utility model. Any modification, equivalent change and decoration made to the above embodiments based on the technical essence of the utility model still fall within the scope of the technical solution of the utility model.
