[0025] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] In the present disclosure, unless otherwise stated, the directional words used, such as "inside" and "outside", refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first" and "second", etc., are used to distinguish one element from another element and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.

[0028] Reference Figure 1 to Figure 2 An example of a fragrance recognition device in a specific embodiment of the present application is provided. A fragrance recognition device is characterized in that it is used to identify the fragrance in a fragrance bottle 3, the fragrance bottle 3 has a light shield 31, the light shield 31 is arranged on the surface of the fragrance bottle 3 and has a color corresponding to the fragrance type, and the fragrance recognition device includes: a controller 1, the controller 1 includes: a transmitter 11, which is used to emit infrared light to the light shield 31; a receiver 12, which is used to receive the infrared light reflected back from the light shield 31. Specifically, the controller 1 is the main board of the fragrance, which is responsible for controlling various functions of the fragrance. The fragrance outputs different fragrance concentrations, selects different fragrance types, etc., which require the controller 1 to send instructions for control; the transmitter 11 is composed of an infrared LED (light emitting diode), and when the sensor is working, the transmitter will emit a beam of infrared light. The receiver 103 is composed of a photosensitive element (photosensitive diode) for receiving the infrared light reflected back from the fragrance bottle.

[0029] According to the fragrance recognition device of this embodiment, the intensity of the reflected infrared light is received by the transmitter 11 and the receiver 12, and converted into electrical signals of different intensities, so as to distinguish different types of fragrances. This method does not require direct contact with the detection object and can achieve non-contact detection operation; the response time of the infrared reflection type sensor is usually very fast, and the detection and feedback of the object can be completed within milliseconds; the infrared reflection type sensor reads the data by receiving the reflected light. The infrared light reflection is stable, and there will be no poor contact problem. In order to more clearly illustrate the scheme of the utility model, the specific operating steps are described. After the transmitter 11 receives the instruction to emit infrared light from the controller 1, the transmitter 11 emits infrared light to the light blocking film 31 on the fragrance bottle 3. After the infrared light contacts the light blocking film 31, it is reflected by the light blocking film 31 to the receiver 12. A part of the reflected infrared light is absorbed by the light blocking film 31. The absorption rate of the infrared light by the light blocking film 31 is affected by the color of the light blocking film. The lighter the color, the lower the absorption rate, the stronger the reflected infrared light, and the stronger the infrared light received by the receiver 12, the greater the current generated.

[0030] In one embodiment, the fragrance identification device further includes: a display module 2, which is connected to the controller 1. The controller 1 is also used to determine the type information of the fragrance according to the infrared light reflected by the light shielding sheet 31 and send the type information to the display module 2. The controller 1 receives a signal for detecting the fragrance category, and the controller 1 sends an instruction for performing fragrance detection, and then the transmitter 11 emits infrared light to the fragrance bottle 3. The infrared light is reflected by the light shielding sheet 31 on the fragrance bottle 3, and is reflected back to the controller 1. The reflected infrared light is received by the receiver 12. The infrared light is reflected by light shielding sheets 31 of different colors, and the intensity of the reflected infrared light is different. The stronger the infrared light received by the receiver 12, the greater the current generated. Different fragrance types can be determined according to the difference in current. In order to facilitate the observation of the selected fragrance type and its information, a display module 2 can be set. The display module 2 can display the type of fragrance, related information, and can display the cause of the problem when an error occurs in the fragrance detection, so as to facilitate the monitoring of the fragrance detection device. It can be understood that the display module 2 includes at least a display screen, which can be a central control screen, an armrest screen, or a small-size, low-resolution display screen. In a preferred embodiment provided in the present application, the display module 2 can be an on-board display screen on a car.

[0031] In one embodiment, the emitter 11 is an infrared light emitting diode. The emitter 11 is composed of an infrared LED (light emitting diode). When the sensor is working, the emitter 11 will emit a beam of infrared light. Infrared light refers to electromagnetic radiation with a wavelength range of 0.75-1000 microns, which is invisible light with a lower frequency than red light.

[0032] In one embodiment, the receiver 12 is a photodiode. The receiver 12 is composed of a photosensitive element (photodiode) for receiving infrared light reflected from the fragrance bottle. A photodiode, also called a photodiode, is a light detector that can convert light into a current or voltage signal depending on how it is used. The tube core often uses a PN junction with a photosensitive characteristic, which is very sensitive to changes in light, has unidirectional conductivity, and changes electrical properties when the light intensity is different. Therefore, the intensity of light can be used to change the current in the circuit. The receiver 12 uses a photodiode, which can keenly capture changes in light and then convert it into an electrical signal, namely a current, and then judge the type of fragrance based on the size of the current.

[0033] On the other hand, the utility model proposes a fragrance bottle 3, characterized in that the fragrance bottle 3 has a light shield 31, which is arranged on the surface of the fragrance bottle 3 and has a color corresponding to the fragrance type. Different lighter colors are sprayed on the light shield 31 to distinguish different fragrance bottles 3. According to research, the light absorbance of the black surface is greater than that of the white surface, so the white surface can reflect most of the light energy; the absorption rate of infrared light on surfaces of other different colors will vary according to the specific color and material. Under the conditions of the same material, the same light intensity and the same surface treatment, the darker color will have a higher absorption rate, while the lighter color may have a lower absorption rate. The lower the absorption rate, the greater the intensity of the reflected infrared light; the greater the light intensity received by the receiver 12 (photodiode), the greater the current generated. Therefore, the lighter the color sprayed on the light shield, the stronger the reflected infrared light, the stronger the current generated by the receiver 12 (photodiode), and it is easier to distinguish different types of fragrances.

[0034] In one embodiment, the light shield 31 is located on the top of the fragrance bottle 3, and is used to reflect the infrared light emitted by the transmitter 11. When working, the transmitter 11 (light emitting diode) emits a beam of infrared light to the light shield 31, and the light shield 31 reflects the infrared light to the receiver 12. The receiver 12 (photosensitive diode) receives the infrared light reflected by the light shield 31 and converts it into a corresponding electrical signal. In this way, different types of fragrance bottles 3 can be determined, thereby achieving the function of identifying fragrance models.

[0035] In one embodiment, perfume is placed inside the fragrance bottle 3. Fragrances are generally divided into three types: liquid fragrances, solid fragrances (furniture fragrances), and bath fragrances. The car-mounted fragrance described in this article uses solid fragrance. The perfume is placed in the fragrance bottle 3, and the information of the perfume is reflected to the receiver 12 (photodiode) by infrared light reflection. The receiver 1 (photodiode) converts different optical signals into different electrical signals. Specifically, perfume is placed inside the fragrance bottle 3, and the perfume evaporates naturally in the fragrance bottle 3 and is discharged to the outside of the fragrance through the airway. A light-blocking sheet 31 of different colors is placed on the top of the fragrance bottle 3 to reflect the infrared light emitted by the transmitter 11 (infrared light-emitting diode) to the receiver 12 (photodiode). The information finally read is transmitted to the display module 2 for display.

[0036] The last aspect of the present invention provides a vehicle, which includes the fragrance recognition device and the fragrance bottle 3 in the above-mentioned embodiment.
