Abstract
Description
Technical Field
[0001] The utility model is applied to the technical field of safety structures of beauty equipment, and particularly relates to a safety device for liquid atomization equipment. Background Art
[0002] In the beauty industry, an appropriate amount of steam and atomized essential oil vapor can provide beauty care for the skin. After using warm steam to steam the face, the pores of the skin can be opened, which helps the secretions of sebum to be excreted in time, and is helpful for acne and seborrheic dermatitis. At the same time, the effect of heat when steaming the face can promote blood circulation in the facial blood vessels, which is also helpful for anti-aging of the face. In order to atomize or heat the liquid, the liquid needs to be stored in a container first, and then the liquid is guided to the atomizer generator through a pump structure or a guide structure. In order to balance the air pressure, the container is usually provided with a breathable structure. When it is accidentally knocked over, the liquid inside the container will be spilled, polluting the environment. At the same time, the steam generating structure needs to heat the water, which may still be in a heating state when it is knocked over. The continuous output of high-temperature steam will bring safety hazards to users. The existing safety device is usually a trigger button set at the bottom of the device. In a normal placement state, the trigger button is pressed to the prevention platform and remains pressed under the weight of the device. When tipping occurs, the trigger button is released to disconnect the steam generator. However, during use, there are situations such as aging or foreign matter adhesion or liquid leakage penetrating into the switch structure that may cause the trigger button to be unable to be released, so the safety of the device cannot be guaranteed.
[0003] If a safety device for liquid atomization equipment can be provided that can realize the dumping power-off function without being interfered by external objects, the above-mentioned technical problems can be well solved. Utility Model Content
[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a safety device for liquid atomization equipment that can realize the dumping and power-off function without being interfered by external objects.
[0005] The technical solution adopted by the utility model is: the utility model includes a device shell, an evaporation atomization module, an MCU module, a ball switch, a power module and a drive module arranged in the device shell, the drive module includes a relay and a switch element, the input end of the power module and the power interface of the evaporation atomization module are both connected to the input port, the relay is connected between the power interface and the input port of the evaporation atomization module, the switch element is connected to the coil of the relay, and the control port of the switch element and the ball switch are both connected to the IO port of the MCU module.
[0006] As can be seen from the above scheme, the MCU module collects the state of the ball switch, and then obtains whether the device is in a tilted state through the ball switch. At the same time, the built-in electronic switch structure is used to prevent foreign matter or liquid intrusion from causing the dumping power-off function to fail, which can better ensure the safety of users. The MCU module controls the drive module, and then controls the power off of the evaporation atomization module, so that it will not continue to output steam or burn empty after dumping.
[0007] A preferred solution is that the power module includes a first power chip and a second power chip which are connected in sequence, and the first power chip is connected to the input port.
[0008] A preferred solution is that the evaporation atomization module is a heating tube evaporation structure or an ultrasonic atomization structure.
[0009] A preferred solution is that the switching element is a triode, one end of the coil of the relay is connected to the output end of the power module, the collector of the switching element (K1) is connected to the other end of the coil of the relay, the emitter of the switching element (K1) is grounded, and the base of the switching element (K1) is connected to the IO port of the MCU module.
[0010] A preferred solution is that the ball switch is a switch element with model SW-520D, the two ends of the ball switch are respectively connected to the output end of the power module and the ground wire, and the IO port of the MCU module is connected to one end of the ball switch.

[0016] As shown in the present embodiment, the power module 4 includes a first power chip U1 and a second power chip U2 connected in sequence, the first power chip U1 is connected to the input port 6, the first power chip U1 converts the input voltage into a 12V voltage and outputs it to the drive module 5, and the second power chip U2 converts the 12V voltage output by the first power chip U1 into 5V and outputs it to the MCU module 2 and the ball switch 3. The first power chip U1 and the second power chip U2 are power chips with models KP3210 and 78L05 respectively.
[0017] In this embodiment, the evaporation atomization module 1 is a heating tube evaporation structure or an ultrasonic atomization structure. The evaporation atomization module 1 extracts the liquid in the container and outputs the liquid in the form of vapor by heating and evaporating it into steam or ultrasonic atomization to perform skin beauty.
[0018] In this embodiment, the switching element K1 is a transistor Q2, one end of the coil of the relay is connected to the output end of the power module 4, the collector of the switching element (K1) is connected to the other end of the coil of the relay, the emitter of the switching element (K1) is grounded, and the base of the switching element (K1) is connected to the IO port of the MCU module 2.

When the device housing is tilted, the ball switch 3 is in the disconnection state and the input voltage is connected to the IO port of the MCU module 2. The IO port of the MCU module 2 is at a high level. The MCU module 2 controls the output to the drive module 5 according to the level state at the IO port so that it cuts off the connection between the evaporation atomization module 1 and the input port 6 when the device housing is tilted.

For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
