Description

Technical Field

[0001] The present invention relates to the technical field of odor generation, and more particularly to an intelligent odor control device and a control method thereof. Background Art

[0002] In many fields such as scientific research, medical health, food safety testing, education and entertainment, odor is an indispensable sensory stimulus, and its generation and control technology is increasingly attracting widespread attention. With its unique function of simulating the odor of a specific environment or object, odor generating devices play an important role in assisting food safety testing, developing medical and health equipment, etc., and are gradually expanding to a wider range of application scenarios, such as scientific research and education and entertainment.

[0003] Traditional odor generating devices mainly generate odors through physical or chemical methods, such as heating, volatilization, chemical reactions, etc. These devices can simulate and generate specific odors to a certain extent, but there are many deficiencies in the diversification of odor types, precise control of odor output concentration, real-time monitoring of odor concentration, and intelligent management. For example, in existing odor generating devices, most of them simulate the corresponding odors by atomizing liquid fragrance sources, which limits the types of odors generated and cannot meet the needs for more complex and diverse odors; Imprecise odor concentration control: Existing devices often find it difficult to achieve precise control of odor output concentration, resulting in poor consistency and repeatability of odor experience, which not only affects the user experience, but also limits the application of the device in situations where high-precision odor control is required; Lack of real-time monitoring and adjustment capabilities: Most devices cannot monitor odor concentration in real time, let alone dynamically adjust according to the monitoring results, which limits the flexibility and accuracy of odor control; Low level of intelligence: The degree of intelligence of existing devices is limited, and it is difficult to achieve automatic control and remote operation, which affects the convenience of use and scope of application; Poor environmental adaptability: When the temperature, humidity or air pressure changes, the odor concentration may be affected, and the odor concentration cannot be adaptively adjusted.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0044] Embodiment 1

[0045] The embodiment of the present invention discloses an intelligent odor control device, such as Figure 1-Figure 4 As shown, it includes 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;

[0046] 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 both include a plurality of odor channels;

[0047] 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;

[0048] 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;

[0049] The liquid odor source module, the solid odor source module and the concentration detection device are all connected to the main controller 13, and are 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;

[0050] The operation interface 11 is connected to the main controller 13 . The operation interface 11 is arranged on the device body and is used to set interface parameters to control the operation status of each odor channel and the current odor concentration through the main controller 13 .

[0051] 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.

The quantity can be adjusted as needed in actual product design.

[0054] like Figure 5 The atomization principle of the liquid odor source module is as follows: the liquid odor source air pump blows air to 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 the air outlet 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.

[0055] The solid odor source module uses a PTC heating module to heat the solid ointment, and the ointment evaporates to generate odor. The solid odor source air pump generates an air flow that is transmitted to the concentration detection device 5 through the air duct.

[0056] In this embodiment, the liquid odor source bottle is a glass bottle, and the solid odor source is an aluminum bottle.

[0057] 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.

[0058] In order to further implement the above technical solution, an intelligent odor control device also includes an external gas pump 21 arranged in the device body, and a residual gas outlet 3 is arranged 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.

[0059] In order to further implement the above technical solution, an odor source exhaust outlet 2 is provided on the side of the device body, and 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 plurality of odor channels. Each odor source exhaust outlet 2 is connected to the air duct, and the number of the odor source exhaust outlets 2 is the sum of the liquid odor source air pumps 19 and the solid odor source air pumps 20.

[0060] 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.

[0061] In order to further implement the above technical solution, an intelligent odor control 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, and a power switch 10 is provided on the device body.

[0062] In actual application, a cooling fan 12 is provided inside the device body to dissipate heat from the main controller and the power board.

[0063] In order to further implement the above technical solution, an intelligent odor control 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.

[0064] In order to further implement the above technical solution, the airway is connected to the breathing mask 6 or the experimental device.

[0065] In order to further implement the above technical solution, each liquid odor source air pump 19 and solid odor source air pump 20 is provided with an air pump base 17 at the bottom and an air pump pressing piece 18 at the top.

[0066] In this embodiment, the STM32 single-chip microcomputer is used as the main controller chip to collect gas concentration, control the operation of the gas pump, control the heating module, drive the display interface, receive instructions, and return data to the PC. Figure 6 The specific working principle is: 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 interface can be used to control the operation of each air pump individually 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.
