[0045] In order to further explain the technical solution of the present invention, the present invention will be elaborated in detail through specific embodiments

[0046] Embodiment 1

[0047] Cooperate with Figures 1 to 8As shown in the figure, in the first embodiment of the present invention, the fragrance bomb 4 may include a fragrance bomb body 41. The fragrance bomb body 41 is provided with an air inlet channel 411, an air outlet channel 412, and a fragrance accommodation cavity 413 for accommodating fragrance substances. The air inlet channel 411 includes a connected first air inlet channel 4111 and a second air inlet channel 4112. The outlet end of the second air inlet channel 4112 communicates with the fragrance accommodation cavity 413. The air outlet channel 412 includes a connected first air outlet channel 4121 and a second air outlet channel 4122. The inlet end of the second air outlet channel 4122 communicates with the fragrance accommodation cavity 413. The outlet end of the second air inlet channel 4112 and the inlet end of the second air outlet channel 4122 are arranged opposite to each other. When the fragrance bomb 4 of the present invention is in use, air enters the fragrance accommodation cavity 413 from the air inlet channel 411 and then is output from the air outlet channel 412. Among them, since the outlet end of the second air inlet channel 4112 of the air inlet channel 411 communicates with the fragrance accommodation cavity 413, the inlet end of the second air outlet channel 4122 of the air outlet channel 412 communicates with the fragrance accommodation cavity 413, and the outlet end of the second air inlet channel 4112 and the inlet end of the second air outlet channel 4122 are arranged opposite to each other, such an arrangement can make the air flowing through the fragrance accommodation cavity 413 fill the fragrance accommodation cavity 413, ensuring that all the fragrance substances in the fragrance accommodation cavity 413 can be effectively affected by the air, and further making the fragrance substances of the fragrance bomb 4 fully used.

[0048] In the first embodiment of the present invention, the fragrance bomb 4 is provided with an intake electromagnetic valve for controlling the opening and closing of the air inlet channel 411 and an outlet electromagnetic valve for controlling the opening and closing of the air outlet channel 412. When the smell of the fragrance substances of the fragrance bomb 4 is not required to be emitted in the present invention, the intake electromagnetic valve can be closed to block the air inlet channel 411 and the outlet electromagnetic valve can be closed to block the air outlet channel 412, so that the fragrance accommodation cavity 413 is closed, which can avoid waste of fragrance substances. When the smell of the fragrance substances of the fragrance bomb 4 needs to be emitted outward in the present invention, the intake electromagnetic valve can be opened to open the air inlet channel 411 and the outlet electromagnetic valve can be opened to open the air outlet channel 412, so that air can flow through the fragrance accommodation cavity 413 and the smell of the fragrance substances of the fragrance bomb 4 can be output outward. The fragrance bomb 4 is further provided with connection terminals 44 electrically connected to the intake electromagnetic valve and the outlet electromagnetic valve. The connection terminals 44 are used for electrically connecting to the control circuit board 3.

[0049] In the first embodiment of the present invention, the intake ferromagnetic body 42 of the intake electromagnetic valve is accommodated in the intake passage 411. The intake ferromagnetic body 42 movably blocks the inlet end of the second intake passage 4112 to control the opening and closing of the intake passage 411. The outlet ferromagnetic body 43 of the outlet electromagnetic valve is accommodated in the outlet passage 412. The outlet ferromagnetic body 43 movably blocks the outlet end of the second outlet passage 4122 to control the opening and closing of the outlet passage 412. The inlet end of the second intake passage 412 of the intake passage 411 and the outlet end of the second outlet passage 412 of the outlet passage 412 are arranged opposite to each other. The magnetism of the intake ferromagnetic body 42 of the intake electromagnetic valve repels the magnetism of the outlet ferromagnetic body 43 of the outlet electromagnetic valve. In this way, when the intake electromagnetic valve and the outlet electromagnetic valve are powered off, due to the repulsion between the intake ferromagnetic body 42 and the outlet ferromagnetic body 43, the intake ferromagnetic body 42 and the outlet ferromagnetic body 43 respectively block the inlet end of the second intake passage 4112 and the outlet end of the second outlet passage 4122 under the action of their own magnetic forces, so as to realize the automatic power-off closing of the intake passage 411 and the outlet passage 412, and further effectively avoid the waste of fragrance substances.

[0050] In the first embodiment of the present invention, the number of the fragrance bombs 4 of the fragrance device of the present invention is at least two. The fragrance bombs 4 are arranged side by side to reduce the space occupation. The control circuit board 3 is electrically connected to the connection terminals 44 of the fragrance bombs 4, so that the control circuit board 3 can control the intake electromagnetic valves and the outlet electromagnetic valves of the fragrance bombs 4. The fragrance bombs 4 of the fragrance device of the present invention can adopt the same type of fragrance bombs 4. In this way, when the fragrance device of the present invention works, the intake electromagnetic valves and the outlet electromagnetic valves of the fragrance bombs 4 can be controlled to open, so that air can flow through the fragrance accommodation cavities 413 of the fragrance bombs 4, thereby quickly improving the smell of the environment. The fragrance bombs 4 of the fragrance device of the present invention can also be different. In this way, the user can control the intake electromagnetic valves and the outlet electromagnetic valves of the required fragrance bombs 4 to open through the control circuit board 3, so that air only flows through the fragrance accommodation cavities 413 of the fragrance bombs 4 required by the user, thereby meeting the personalized use needs of the user.

[0051] In the first embodiment of the present invention, the fragrance bomb body 41 may include a fragrance bomb outer shell 4101 and a fragrance bomb inner seat 4102 disposed in the fragrance bomb outer shell 4101. The fragrance bomb outer shell 4101 includes a first shell cover 41011, a second shell cover 41012, and a shell base 41013. Both sides of the shell base 41013 are respectively connected to the first shell cover 41011 and the second shell cover 41012. A fragrance accommodation cavity 413 is formed between the shell base 41013 and the first shell cover 41011. The shell base 41013 and the first shell cover 41011 can be connected by ultrasonic welding to ensure the sealing of the fragrance accommodation cavity 413. An inner seat accommodation cavity 415 is formed between the shell base 41013 and the second shell cover 41012. The inner seat accommodation cavity 415 is separated from the fragrance accommodation cavity 413. The fragrance bomb inner seat 4102 is installed in the inner seat accommodation cavity 415, and the fragrance bomb inner seat 4102 is in sealed plug-in fit with the first shell cover 41011, the second shell cover 41012, and the shell base 41013. The fragrance bomb inner seat 4102 is provided with the air inlet channel 411 and the air outlet channel 412. The air inlet channel 411 and the air outlet channel 412 are separated by a silica gel pad 414. The air inlet solenoid valve and the air outlet solenoid valve are installed in the fragrance seat inner seat 4102. A fragrance bomb circuit board 45 is further installed in the inner seat accommodation cavity 415. The fragrance bomb circuit board 45 is electrically connected to the air inlet solenoid valve and the air outlet solenoid valve. The fragrance bomb circuit board 45 is provided with connection terminals 44 to be electrically connected to the control circuit board 3. The fragrance bomb circuit board 45 can identify the type of the fragrance bomb 4 through RFID technology and send the corresponding information to the control circuit board 3. The present invention separates the inner seat accommodation cavity 415 and the fragrance accommodation cavity 413 in the fragrance bomb body 41. In this way, when assembling the fragrance bomb body 41, the fragrance substance can be first placed between the shell base 41013 and the first shell cover 41011, and the shell base 41013 and the first shell cover 41011 are ultrasonically welded. Then, the fragrance bomb inner seat 4102 and the control circuit board 3 are installed between the shell base 41013 and the second shell cover 41012, and the shell base 41013 and the second shell cover 41012 are connected. By assembling the fragrance bomb body 41 in this way, the fragrance substance can be effectively prevented from being contaminated, and the inner seat accommodation cavity 415 does not need to have sealing requirements, so that the shell base 41013 and the second shell cover 41012 do not need to be welded, which helps to simplify the assembly process of the fragrance bomb body 41.

[0052] In the first embodiment of the present invention, the fragrance device of the present invention may further include an airway seat 6. The airway seat 6 is installed in the fragrance seat 1. The airway seat 6 is provided with an airway inner cavity 61, an airway inlet 62 communicating with the airway inner cavity 61, and at least one airway outlet 63 communicating with the airway inner cavity 61. The airway inlet 62 is communicated with the air outlet of the micro piezoelectric ceramic air pump 2, and each airway outlet 63 is respectively inserted and communicated with the inlet end of the first air inlet channel 4111 of each fragrance bomb 4. In this way, the air outlet of the micro piezoelectric ceramic air pump 2 is communicated with the inlet end of the first air inlet channel 4111 of each fragrance bomb 4 through the airway seat 6. Moreover, the setting of the airway seat 6 enables the fragrance device of the present invention to only need to be provided with one micro piezoelectric ceramic air pump 2, which helps to reduce the volume of the fragrance device 2 of the present invention. Wherein, the airway seat 6 may include a connected inner cover 601 and an airway cover 602, which facilitates the setting of the airway inner cavity 61, the airway inlet 62 and the airway outlet 63.

[0053] In the first embodiment of the present invention, the fragrance seat 1 may be provided with an installation cavity 11 with an open top; the fragrance bomb 4, the airway seat 6, the micro piezoelectric ceramic air pump 2 and the control circuit board 3 are sequentially installed in the installation cavity 11 from top to bottom; such a setting can make the structure of the fragrance device of the present invention compact and is beneficial to reducing the volume of the fragrance device of the present invention.

[0054] In the first embodiment of the present invention, the fragrance device of the present invention may further include a fragrance cover 7 connected to the fragrance seat 1. The fragrance cover 7 is provided with an installation opening 71 for fitting with each fragrance bomb 4 to detachably cooperate the fragrance bomb 4 with the fragrance seat 1; the fragrance cover 7 and the fragrance seat 1 can be detachably connected by a snap connection method for easy disassembly and assembly of the fragrance cover 7. The orientations of the first air inlet channel 4111 of the air inlet channel 411 of the fragrance bomb 4 and the first air outlet channel 4121 of the air outlet channel 412 may be set in opposite directions, which facilitates the docking of the first air inlet channel 4111 with the airway outlet 63 and at the same time avoids the fragrance cover 7 and the fragrance seat 1 from affecting the air outlet of the first air outlet channel 4121.

[0055] In the first embodiment of the present invention, the fragrance seat 1 may be provided with installation holes 12 adapted to a standard 86 bottom box. In this way, the fragrance device of the present invention can be installed in the standard 86 bottom box of the user's residence, reducing the space occupied by the fragrance device of the present invention in the user's residence.
