[0027] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a vending machine perfume spray experience device, including a spray panel 1, the spray panel 1 having a plurality of spray outlets 2, a mounting frame 3 connected to the back of the spray panel 1, a plurality of perfume spray components 4 being disposed inside the mounting frame 3, each perfume spray component 4 being configured with a spray outlet 2;

[0029] The perfume spray assembly 4 includes an atomizing nozzle 5 and a perfume container 6, which are screwed together. The atomizing nozzle 5 includes a nozzle housing 7, an ultrasonic atomizing plate 8 is provided on the side of the nozzle housing 7, and a horizontal water-guiding cotton rod 9 is provided inside the nozzle housing 7. A vertical water-guiding cotton rod 10 is connected below the horizontal water-guiding cotton rod 9 and extends into the interior of the perfume container 6.

[0030] The nozzle housing 7 is also equipped with a pressure spring 11 inside, which presses the transverse water-guiding cotton rod 9 against the ultrasonic atomizing plate 8.

[0031] In this embodiment, there are four spray nozzles 2 and four sets of perfume spray components 4. Each perfume spray component 4 can hold different scents in its perfume container 6. The perfume sprayed from the perfume spray component 4 is released to the user through the spray nozzles 2, allowing the user to experience and select different perfumes.

[0032] The atomizing nozzle 5 and the perfume container 6 are divided into upper and lower parts and placed on the mounting frame 3. The atomizing nozzle 5 and the perfume container 6 are screwed together to facilitate the replenishment of perfume liquid into the perfume container 6. When the ultrasonic atomizing plate 8 is installed on the nozzle housing 7 of the atomizing nozzle 5, the internal horizontal water-guiding cotton rod 9 is given slight pressure by the pressure spring 11, so that the contact surface of the horizontal water-guiding cotton rod 9 is completely in contact with the ultrasonic atomizing plate 8. The ultrasonic atomizing plate 8 is pressed tightly at the spray port 2 by the spray panel 1. The horizontal water-guiding cotton rod 9 and the vertical water-guiding cotton rod 10 are in a T-shape structure. The perfume liquid is drawn upward from the perfume container 6 through the vertical water-guiding cotton rod 10 into the horizontal water-guiding cotton rod 9, and then guided to the nozzle of the ultrasonic atomizing plate 8.

[0033] In this embodiment, the atomization level can be finely adjusted by adjusting the tightness of the spray panel 1. Since the vending machine perfume spray experience device needs to work for a long time, in order to avoid the solution clogging the atomizing plate and the decrease in the water conductivity of the cotton swabs after long-term use, the ultrasonic atomizing plate 8, the horizontal water-guiding cotton swabs 9, and the vertical water-guiding cotton swabs 10 in the device are all designed in a modular manner, which facilitates disassembly, cleaning, and replacement.

[0034] In one possible embodiment, a support plate 12 is provided in the middle of the mounting frame 3, and two sets of perfume spray assemblies 4 are respectively provided on both sides of the support plate 12; a baffle 13 is connected to the outer side of the support plate 12. Through the cooperation of the support plate 12 and the baffle 13, the perfume spray assembly 4 in the mounting frame 3 is fixed to ensure the stability of the perfume spray assembly 4.

[0035] See Figure 6 , Figure 7 , Figure 8 and Figure 9 In one possible embodiment, the device further includes an atomization main control board 14, which integrates an atomization main control MCU 15. The atomization main control MCU 15 is connected to a USB-to-serial module, which is used for communication between the vending machine perfume spray experience device and the host computer. The atomization main control board 14 also integrates an atomization driver module 16, which is electrically connected to the atomization main control MCU 15. The atomization driver module 16 outputs a high-frequency signal through an IC pin, which triggers the ultrasonic atomizing plate 8 to operate via a MOSFET. The device also includes an LED indicator 17, which is electrically connected to the atomization main control MCU 15 and is used to indicate the perfume spray switch, power supply, and serial communication status.

[0036] Specifically, the atomization main control MCU15 of the atomization main control board 14 uses an STC15W204S microcontroller as its control core. The atomization main control MCU15 communicates with the host computer via the ch340n USB interface to obtain instructions. The IO ports P32 / 33 / 54 / 55 control the atomization drive module 16 circuit through AO3401 field-effect transistors. Each IO port has an independently operating LED indicator 17, which is stabilized in the off state by a 10K pull-up resistor. The output port freewheeling diode FR107W prevents reverse voltage breakdown of the subsequent atomization drive circuit from damaging the main control components.

[0037] The RST button serves as a power-off reset button. An A03401 MOSFET controls the power supply of the atomization main control MCU15, which is kept on by a pull-down resistor and powered off when pressed. The USB interface is protected by a TVS diode (SMF5.0A). The USB-to-serial converter has indicator lights for both transmission and reception to display the communication status, and a B5817WS and a 270Ω resistor are used to prevent backflow of current when the USB is powered off. The atomization drive outputs a 100kHz high-frequency signal through the IC pin, which triggers the microporous atomizing plate through a MOS transistor.

[0038] In one possible embodiment, a power module is also included, which is electrically connected to the atomizing main control MCU15. The power module is used to supply power to the vending machine perfume spray experience device.

[0039] Specifically, the power module uses an external USB power supply with an internal 3.3V voltage regulator, and the output atomizing terminal uses USB 5V voltage. Furthermore, the vending machine perfume spray experience device connects to the host computer via a standard USB 2.0 interface. The entire device is powered entirely by the USB interface, with a power consumption of less than 2.5W; it uses a custom serial port protocol for control, supporting a maximum baud rate of 115200bps.

[0040] In summary, this utility model features a spray panel 1 with a spray opening 2, and a plurality of perfume spray components 4 housed within the mounting frame 3. The nozzle housing 7 of each perfume spray component 4 has an ultrasonic atomizing plate 8 on its side. Inside the nozzle housing 7, a horizontal water-guiding cotton rod 9 is provided, with a vertical water-guiding cotton rod 10 connected below it, extending into the perfume container 6. Simultaneously, a pressure spring 11 is also provided inside the nozzle housing 7, pressing the horizontal water-guiding cotton rod 9 against the ultrasonic atomizing plate 8. The atomizing nozzle 5 and the perfume container 6 are separated into upper and lower parts and placed within the mounting frame 3. The atomizing nozzle 5 and the perfume container 6 are screwed together, facilitating the replenishment of perfume liquid into the perfume container 6. When the ultrasonic atomizing plate 8 is installed on the nozzle housing 7 of the atomizing nozzle 5, the internal horizontal water-guiding cotton rod 9 is slightly pressured by the pressure spring 11, ensuring complete contact between the horizontal water-guiding cotton rod 9 and the ultrasonic atomizing plate 8. The spray panel 1 presses the ultrasonic atomizing plate 8 firmly at the spray opening 2. The horizontal water-guiding cotton swab 9 and the vertical water-guiding cotton swab 10 are T-shaped. The perfume solution is drawn upward from the perfume container 6 through the vertical water-guiding cotton swab 10 and then guided to the nozzle of the ultrasonic atomizing plate 8. The atomization level can be finely adjusted by adjusting the tightness of the spray panel 1. Since the vending machine perfume spray experience device needs to work for a long time, in order to avoid the solution clogging the atomizing plate and the decrease in the water conductivity of the cotton swabs after long-term use, the ultrasonic atomizing plate 8, the horizontal water-guiding cotton swab 9, and the vertical water-guiding cotton swab 10 in the device are all modularly designed for easy disassembly, cleaning, and replacement. This utility model is suitable for application in smart vending machine sampling and sales scenarios; it can achieve 90° horizontal spraying, and there will be no water leakage from the atomizing plate or the nozzle structure during long-term operation, which is highly reliable and allows users to experience the perfume product before delivery, so that users can choose a satisfactory perfume.
