Detailed Implementation

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the invention and are not intended to limit the scope of protection of the invention. For example, although this application is described in conjunction with an air fragrance regulator, the technical solution of the present invention is not limited thereto, and this control method can obviously also be applied to air conditioners with fragrance regulation functions; such a change does not depart from the principles and scope of the present invention. Those skilled in the art can make adjustments as needed to adapt to specific applications.

[0025] It should be noted that although the steps of the control method of the present invention are described in a specific order in the description of the present invention, these orders are not restrictive. Without departing from the basic principles of the present invention, those skilled in the art can perform the steps in different orders.

[0026] First refer to Figure 1 The figure is a schematic diagram of a preferred embodiment of the air fragrance regulator of the present invention. Figure 1 As shown, the air fragrance regulator of the present invention includes a housing 1, an air inlet pipe 2 and an air outlet pipe 3 connected to the housing 1, and a fragrance release channel 101 and a fragrance absorption channel 102 disposed within the housing 1. The fragrance release channel 101 contains a container 4, a fragrance release agent adjustment component 5, and a first one-way valve 8. The container 4 contains a volatile fragrance agent. The fragrance absorption channel 102 contains a second one-way valve 9. A fan 7 is disposed within the air inlet pipe 2, which promotes air circulation between the air fragrance regulator and the ambient space, blowing the fragrance gas into the ambient space and allowing air from the ambient space to enter the air fragrance regulator. The fragrance release channel 101 is connected to the air inlet pipe 2 and the air outlet pipe 3. By controlling the fan 7 to rotate forward, air enters through the air inlet pipe 2. Under the action of the first one-way valve 8, the air in the air inlet pipe 2 can only enter the fragrance release channel 101, and the fragrance gas is released into the ambient space through the air outlet pipe 3. The fragrance absorption channel 102 can be connected to the air inlet pipe 2 and the air outlet pipe 3. By controlling the fan 7 to reverse, air enters through the air outlet pipe 3. Under the action of the second one-way valve 9, the air in the air outlet pipe 3 can only enter the fragrance absorption channel 102 and then be released into the ambient space through the air inlet pipe 2.

[0027] Continue as Figure 1As shown, a partition 103 is provided between the fragrance release channel 101 and the fragrance absorption channel 102, and an opening for air flow is provided between the partition 103 and the bottom of the outer casing 1. The partition 103 can separate the fragrance release channel 101 and the fragrance absorption channel 102. Specifically, when fragrance is released, due to the forward rotation of the fan 7 and the setting of the second one-way valve 9, air can only enter the fragrance release channel 101 through the opening. When fragrance is absorbed, due to the reverse rotation of the fan 7, air flows in through the air outlet pipe and flows out through the air inlet pipe. The partition 103 separates the fragrance absorption channel 102 and the fragrance release channel 101, preventing the air after absorbing fragrance from entering the fragrance release channel 101.

[0028] Then refer to Figure 4 The figure shows a flowchart of the main steps of the control method for the air fragrance regulator of the present invention. Figure 4 As shown, the control method of the present invention mainly includes the following steps:

[0029] S1, after the fragrance release agent adjustment component and the fan are started, obtain the actual indoor fragrance concentration;

[0030] S2, determine if there is anyone inside;

[0031] S3, when the judgment result is that there is no one in the room and the duration of the no one state reaches the preset time, selectively control the operation of the fragrance release agent adjustment component and / or the fan to reduce the actual fragrance concentration in the room to the preset fragrance concentration.

[0032] In the above steps, for example, such as Figure 1 As shown, a concentration sensor 11 is installed inside the air outlet duct 3 to detect the actual fragrance concentration in the room. Of course, the concentration sensor 11 can also be installed in other locations besides the air outlet duct 3, as long as it can detect the actual fragrance concentration in the room. This invention does not impose any restrictions on the location of the concentration sensor. Figure 3 As shown, a position sensor 13 is provided on the outer casing 1 to detect whether there is a person in the room and the person's location. Of course, the position sensor 13 can also be placed in other locations besides the outer casing 1, as long as it can detect whether there is a person and the person's location. This invention does not impose any restrictions on the placement of the position sensor.

[0033] The fragrance release adjuster 5 includes an ultrasonic oscillator and / or an electric heating element, with the container 4 disposed on the ultrasonic oscillator and the electric heating element disposed at the bottom of the container 4. "Controlling the operation of the fragrance release adjuster 5" refers to controlling the operation of at least one of the ultrasonic oscillator and the electric heating element.

[0034] In an embodiment of the present invention, the control method of the present invention controls the operation of the air fragrance regulator by determining whether there are people in the room. When there are no people, the actual fragrance concentration in the room decreases. In this way, when people enter the room again, they will not feel that the fragrance is pungent due to the difference in fragrance concentration between indoors and outdoors, thus avoiding physical discomfort.

[0035] Preferably, step S3 further includes:

[0036] S31, when the judgment result is that there is no one in the room and the duration of the no one state reaches the first preset time, the fragrance release agent adjustment component 5 is stopped, and the fan 7 continues to run;

[0037] S32, when the judgment result is that there is no one in the room and the duration of the no one state reaches the second preset time, control the fan 7 to reverse so that the fragrance gas in the room is discharged to the outside.

[0038] The first preset time is shorter than the second preset time.

[0039] For example, the first preset time is 5 minutes and the second preset time is 15 minutes. If the room is unoccupied for 5 minutes, the fragrance release adjuster 5 is controlled to stop operating and the fragrance release is paused. Only the fan 7 is operated to achieve air circulation. In this way, the overall fragrance concentration released by the air fragrance regulator gradually decreases. If the room is still unoccupied for 15 minutes, the fan 7 is controlled to reverse and discharge the fragrance gas in the room to the outside through the air intake pipe 2, so that the fragrance concentration in the room is reduced to the preset concentration and then stops.

[0040] It should be noted that, in addition to being connected to the indoor environment to achieve indoor air circulation, the air intake pipe 2 can also be connected to the outdoor environment to achieve air circulation between indoor and outdoor environments. Specifically, the air intake pipe 2 can be connected to the indoor / outdoor environment by switching valves.

[0041] In an alternative embodiment, the air fragrance regulator further includes a fragrance absorber, and step S3 further includes:

[0042] S33, when the judgment result is that there is no one in the room and the duration of the no one state reaches the second preset time, control the fan to reverse so that the fragrance gas in the room is absorbed by the fragrance absorption element and then discharged into the room.

[0043] For example, the second preset time is 15 minutes. If the room remains unoccupied for 15 minutes, the fan 7 is reversed to absorb the fragrance gas in the room and then discharge it into the room through the air intake pipe 2, so that the fragrance concentration in the room is reduced to the preset concentration and then stopped.

[0044] In the above steps, the fragrance absorbing element is configured as a fragrance adsorbent 6, and the fragrance adsorbent 6 is disposed within the fragrance absorption channel 102 (e.g., Figure 1 As shown, the fragrance adsorbent 6 can be activated carbon, which can absorb the fragrance gas passing through the fragrance absorption channel 102. Of course, the fragrance adsorbent 6 can also be other adsorbents besides activated carbon, as long as they have the function of fragrance adsorption. This invention does not limit the type of fragrance adsorbent 6.

[0045] The control method of the present invention further includes:

[0046] S4, if the result indicates that someone is indoors, obtain the user's location;

[0047] S5 controls the air fragrance regulator to blow fragrance gas toward the user's location.

[0048] In step S4, the user's position is obtained via position sensor 13. In step S5, the air fragrance regulator also includes an airflow adjustment device 12 (such as...). Figure 1 As shown), the outer casing 1 is connected to the air outlet pipe 3 via the air direction adjustment device 12, allowing the air outlet pipe 3 to rotate relative to the outer casing 1, so that the air outlet pipe 3 can blow the fragrance gas toward the user's position. Furthermore, the number of air outlet pipes 3 can be set by those skilled in the art as needed. In this embodiment, two air outlet pipes 3 are provided (e.g., Figure 2 As shown), each air outlet duct 3 is capable of blowing scented gas toward the user's location. For example, as... Figure 3 As shown, the airflow adjustment device 12 includes a first motor 1201, a second motor 1203, and a support 1202. The air outlet pipe 3 is rotatably fixed on the support 1202. The drive end of the first motor 1201 is connected to the air outlet pipe 3 to drive the air outlet pipe 3 to rotate up and down relative to the support 1202. The drive end of the second motor 1203 is connected to the first support 1202 and is mounted on the outer casing 1 to drive the support 1202 and the air outlet pipe 3 to rotate left and right relative to the outer casing 1 in sequence. Through the airflow adjustment device 12, the air outlet pipe 3 can rotate in four directions (up, down, left, and right), resulting in a wider airflow range and broader applicability. Of course, the airflow adjustment device 12 can also be other structures besides the one described above, as long as it allows the air outlet pipe 3 to rotate relative to the outer casing 1. Additionally, as another embodiment, a guide vane can be provided inside the air outlet pipe 3, and the direction of the exhaust airflow can be changed by adjusting the direction of the guide vane.

[0049] Preferably, the control method of the present invention further includes:

[0050] S6, based on the distance between the user's location and the air fragrance regulator, and the mapping relationship between the distance and the operating power of the fragrance releaser adjustment component 5 and / or the rotation speed of the fan 7, control the operation of the fragrance releaser adjustment component 5 and / or the fan 7;

[0051] S61, as the distance increases, the operating power of the fragrance releaser adjuster 5 and / or the speed of the fan 7 are increased;

[0052] S62, when the distance is closer, reduce the operating power of the fragrance releaser adjuster 5 and / or the speed of the fan 7.

[0053] Preferably, the air fragrance regulator also includes a valve 10 (such as...). Figure 1 As shown, valve 10 is installed within the air outlet pipe 3, which connects to the ambient space via valve 10. Airflow is adjusted by controlling the opening of valve 10. Valve 10 can be an electric regulating valve, a proportional valve, etc. It should be noted that although this invention is described in conjunction with the installation of valve 10 within the air outlet pipe 3, this is not a limitation. Those skilled in the art can also, as needed, install valve 10 within the air inlet pipe 2, or install valve 10 in both the air inlet pipe 2 and the air outlet pipe 3. These adjustments do not depart from the principles of this invention and therefore fall within the scope of protection of this invention.

[0054] The control method of the present invention further includes:

[0055] S71, the opening of valve 10 is reduced as the distance increases;

[0056] S72, the closer the distance, the greater the opening of valve 10.

[0057] In the above steps, the operating power of the fragrance release agent adjuster 5 and / or the speed of the fan 7 and the opening degree of the valve 10 are controlled according to the user's location to ensure that the user can quickly smell the fragrance in a relatively large indoor space, while avoiding the fragrance being too strong when the user is too close. Specifically, if the number of people is small and the number of people is the same as the number of air outlet pipes 3, for example, if there are two people and two air outlet pipes 3, each air outlet pipe 3 blows fragrance gas toward the user closest to it according to the principle of proximity. If the number of people is small and the number of people is less than the number of air outlet pipes 3, for example, if there is one person and there are two air outlet pipes 3, then both air outlet pipes 3 blow fragrance gas toward the user's location. If the number of people is large and the number of people is greater than the number of air outlet pipes 3, for example, if there are three or more people and there are two air outlet pipes 3, first obtain the location of each user, then obtain the boundary position based on the location of each user, and then obtain the center position based on the boundary position. Then the air outlet pipe 3 blows fragrance gas toward the center position.

[0058] The control method of the present invention further includes:

[0059] S8, before the fragrance releaser adjuster 5 and the fan 7 are started, obtain user information and / or context information;

[0060] S9 determines the concentration of fragrance released into the room based on user information and / or contextual information.

[0061] In the above steps, users can pre-store the mapping relationship between scene information and / or user information and fragrance concentration in a database, and determine the fragrance concentration to be released into the room based on this mapping relationship, thus achieving personalized customization. For example, after obtaining the user's location, a facial recognition sensor can be set up to match the corresponding scene information after facial recognition of the user, and release the corresponding fragrance concentration according to the scene information. Alternatively, after facial recognition of the user, the corresponding fragrance concentration can be released directly. Or, the user can pre-select the corresponding scene mode in the program, and release the corresponding fragrance concentration according to the scene information. These adjustments do not depart from the principle of the present invention, and therefore also fall within the protection scope of the present invention.

[0062] See below. Figure 5 This figure is a possible complete flowchart of the control method for the air fragrance regulator of the present invention. Figure 5 As shown, a possible complete flow of the control method for the air fragrance regulator of the present invention is as follows:
