Description

Intelligent odor concentration adjustment device and application method thereof Technical Field

[0001] The present invention relates to the field of odor generation technology, and more particularly to an intelligent odor concentration adjustment device and an application method thereof. Background Art

[0002] As an essential sensory stimulus, odor generation and control technologies are gaining increasing attention in fields such as scientific research, healthcare, food safety testing, and education and entertainment. Odor-generating devices, with their unique ability to simulate the scent of specific environments or objects, play a vital role in assisting food safety testing and developing medical and healthcare equipment. These applications are gradually expanding to a wider range of fields, including scientific research, education, and entertainment.

[0003] Traditional odor-generating devices primarily generate odors through physical or chemical methods, such as heating, volatilization, and chemical reactions. While these devices can simulate and produce specific odors to a certain extent, they lack the ability to diversify odor types, precisely control odor output concentration, monitor odor concentration in real time, and manage them intelligently. For example, most existing odor-generating devices simulate and produce corresponding odors through atomization of a liquid fragrance source, which limits the types of odors produced and fails to meet the demand for more complex and diverse odors. Inaccurate odor concentration control: Existing devices often struggle to precisely control odor output concentration, resulting in poor consistency and repeatability in the odor experience. This not only impacts the user experience but also limits their application in situations requiring high-precision odor control. Lack of real-time monitoring and adjustment capabilities: Most devices are unable to monitor odor concentration in real time, let alone dynamically adjust it based on the monitoring results, limiting the flexibility and accuracy of odor control. Low intelligence: Existing devices have limited intelligence, making automated control and remote operation difficult, impacting their ease of use and scope of application. Poor environmental adaptability: Changes in temperature, humidity, or air pressure can affect odor concentration, making adaptive adjustment impossible.

[0004] Therefore, how to achieve the diversification of odor sources and applicable scenarios and the intelligent and precise control of odor concentration is an urgent problem that technicians in this field need to solve.

[0005] Summary of the Invention

[0013] The operation interface is connected to the main controller and is located on the device body. It is used to set interface parameters to control the operating status of each odor channel and the current odor concentration through the main controller.

[0015] Enter the main interface of the device: After the power is turned on, press the power switch of the device to start the device and enter the main interface. The main interface displays the operating status of each odor channel and the current odor concentration;

DETAILED DESCRIPTION

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Example 1

[0038] The embodiment of the present invention discloses an intelligent control odor concentration adjustment device, as shown in Figures 1 to 4, comprising a device body, including a liquid odor source module, a solid odor source module, an air guide tube, a concentration detection device 5, a main controller 13 and an operation interface 11;

[0039] The liquid odor source module and the solid odor source module are arranged in the device body, and are used for the liquid odor source and the solid odor source to generate corresponding odor gases. The liquid odor source module and the solid odor source module each include a plurality of odor channels;

[0040] The liquid odor source module and the solid odor source module are connected to the air duct to guide the odor gas out through the air duct;

[0041] The concentration detection device 5 is fixedly connected to the air duct and is used to detect the concentration of the odor gas and transmit it to the main controller 13;

[0042] The liquid odor source module, the solid odor source module, and the concentration detection device are all connected to the main controller 13, which is used to obtain the concentration of the odor gas detected by the concentration detection device 5 and control the concentration of the corresponding odor gas generated by the corresponding odor source according to the concentration value;

[0043] The operation interface 11 is connected to the main controller 13. The operation interface 11 is set on the device body and is used to set interface parameters to control the operating status of each odor channel and the current odor concentration through the main controller 13.

[0044] The concentration detection device 5 is connected to the main controller 13 via a concentration detection connection, and the user transmits detection data and control instructions.

[0045] In order to further implement the above technical solution, the liquid odor source module includes an atomization device, several liquid odor source bottles and a corresponding equal number of liquid odor source air pumps 19; the solid odor source module includes a solid heating module 16, several solid odor source aluminum bottles 15 and a corresponding equal number of solid odor source air pumps 20; the liquid odor source air pump 19 and the solid odor source air pump 20 are connected to the air duct.

[0046] In this embodiment, there are 6 liquid odor source bottles, each of which is equipped with an atomizing device and a liquid odor source air pump. There are 2 solid odor source aluminum bottles, each of which is equipped with a PTC solid heating module and a solid odor source air pump. The quantity can be adjusted as needed in actual product design.

[0047] As shown in Figure 5, the atomization principle of the liquid odor source module is as follows: the liquid odor source air pump blows air into the atomization device. Since the interface diameter of the straw of the liquid odor source bottle is larger than the air outlet of the atomization device, the air pressure at this position will be lower than the air pressure of the straw, thus generating a negative pressure. The liquid in the bottle will be sucked up by the air pressure, and will be sprayed out after the air is exhausted to generate atomization, which will be transmitted to the concentration detection device 5 through the one-way valve and the air guide tube.

[0048] The solid odor source module uses a PTC heating module to heat the solid ointment, causing the ointment to evaporate and generate odor. The solid odor source air pump generates air flow that is transmitted to the concentration detection device 5 through the air duct.

[0049] In this embodiment, the liquid odor source bottle is a glass bottle, and the solid odor source is an aluminum bottle.

[0050] In this embodiment, a liquid odor source rear cover 4 and a solid odor source rear cover 7 are provided on the side of the device body corresponding to the position of the odor source bottle, so as to facilitate the replacement of the odor source bottle.

[0051] In order to further implement the above technical solution, the intelligent odor concentration adjustment device also includes an external gas pump 21 arranged in the device body, and a residual gas outlet 3 is provided on the side of the device body. The external gas pump 21 is connected to the air duct through the residual gas outlet 3 to form an air channel, which is used to dilute and adjust the concentration of the odor gas in each odor channel by pumping in air, and to deodorize the odor channel through air after each odor channel has released the odor.

[0052] In order to further implement the above technical solution, an odor source exhaust outlet 2 is provided on the side of the device body. Each liquid odor source air pump 19 or each solid odor source air pump 20 is connected to an odor source exhaust outlet 2 to form a number of odor channels. Each odor source exhaust outlet 2 is connected to the air duct, and the number of odor source exhaust outlets 2 is the sum of the liquid odor source air pumps 19 and the solid odor source air pumps 20.

[0053] In order to further implement the above technical solution, the operation interface 11 is specifically used to control the operating status of each odor channel and the current odor concentration by setting the rotation speed of each air pump, the heating temperature of the solid heating module, and the deodorization time.

[0054] In order to further implement the above technical solution, the intelligent odor concentration adjustment device also includes a power board 14. A power socket 8 is provided on the side of the device body. The power board 14 is connected to the main controller 13 to supply power to various components of the device. A power switch 10 is provided on the device body.

[0055] In actual application, a cooling fan 12 is provided inside the device body to dissipate heat from the main controller and the power board.

[0056] In order to further implement the above technical solution, the intelligent odor concentration adjustment device also includes a concentration detection software wiring socket 9, one end of the concentration detection software wiring socket 9 is connected to the main controller 13, and the other end is connected to the remote terminal through the concentration detection software USB wiring, which is used to collect the concentration value at each collection time, and remotely control the odor control device through serial port instructions.

[0057] In order to further implement the above technical solution, the airway is connected to the breathing mask 6 or the experimental device.

[0058] In order to further implement the above technical solution, an air pump base 17 is provided at the bottom of each liquid odor source air pump 19 and solid odor source air pump 20, and an air pump pressing piece 18 is provided at the top.

[0059] In this embodiment, an STM32 single-chip microcomputer is used as the main controller chip for collecting gas concentration, controlling the operation of the air pump, controlling the heating module, driving the display interface, receiving instructions, and transmitting data back to the PC, etc. As shown in Figure 6, the specific working principle is as follows: the main controller chip collects the voltage value of the output pin of the concentration detection device (VOC sensor) in real time, and obtains an accurate voltage value after ADC conversion and filtering. Based on the functional relationship between the voltage value and the VOC gas concentration, the actual VOC gas concentration value can be solved and the data can be pushed to the PC in real time. According to the VOC gas concentration value, the operation of each air pump can be controlled separately through the operation interface to generate odor independently, and the air flow rate can be controlled by adjusting the air pump speed of each channel to obtain different concentrations.

[0061] The application method of the intelligent control odor concentration regulating device is based on the intelligent control odor concentration regulating device, including:

[0065] Select the corresponding channels of the liquid odor channel and the solid odor channel to generate the corresponding odor source odor, and detect the odor concentration through the concentration detection device. Then, based on the setting interface or the remote control terminal, adjust the speed of the liquid odor source air pump, the solid odor source air pump and the external gas air pump to adjust the odor concentration of the odor source. The air pump speed can be adjusted from 50% to 100%, and the deodorization time can be set from 0 to 120 seconds, as shown in Figure 10;

[0066] When switching the odor channel, connect the corresponding odor channel and pump air into the airway through the external gas pump to deodorize the airway;
