For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0043] See also Figures 1 to 8 The utility model discloses a multi-air pump aroma diffuser, including at least two air pumps 1, a mounting base 2 and an atomizing assembly 4. The mounting base 2 is provided with a receiving cavity 201 for mounting an essential oil bottle 3 and an atomizing assembly 4. The air pump 1 is fixed on the mounting base 2; the air outlet of the air pump 1 is connected to the atomizing position of the atomizing assembly 4 through an airflow duct 5; the airflow of the air pump 1 atomizes the essential oil in the essential oil bottle 3 through the atomizing assembly 4 and scatters it out of the aroma diffuser. Specifically, the air pump 1 generates an airflow with a constant speed, which enters the atomizing assembly 4 through the airflow duct 5, provides a stable gas for the atomizing assembly 4, and the atomizing assembly 4 converts the constant airflow into a high-pressure airflow. According to the Venturi effect, the high-pressure airflow breaks up the essential oil in the essential oil bottle 3 into micron-sized particles, which float upward out of the aroma diffuser.

[0044] In this embodiment, an elastic member 101 is also included, which is sleeved on the outer surface of the air pump 1. The air pump 1 is fixed to the outer periphery of the accommodating cavity 201 through the elastic member 101 and does not directly contact the mounting seat 2. The air pump 1 will vibrate when working, and the elastic member 101 forms a soft connection between the air pump 1 and the mounting seat 2, which reduces the impact of the air pump 1 on the surrounding area when vibrating, plays a noise reduction effect, and provides a better user experience.

[0045] In this embodiment, an air inlet end 202 receiving the air flow pipe 5 is further provided on the outer wall of the accommodating chamber 201, and the air pump 1 converges at the air inlet end 202 through the air flow pipe 5, and the air inlet end 202 is connected to the atomizing assembly 4 through the first air flow channel 1101. Specifically, the air outlets of each air pump 1 are respectively connected to the bifurcated sections of the air flow pipe 5, and the bifurcated sections converge when approaching the air inlet end 202, so there is no need to open an air inlet end 202 for each air pump 1, and the structure is simpler.

[0046] Furthermore, in this embodiment, a cylindrical accommodating chamber 201 is provided in the middle of the mounting base 2, the air pump 1 and the airflow duct 5 are arranged on the outer periphery of the accommodating chamber 201, and the air inlet end 202 is used to receive the airflow of the air pump 1, so that the airflow enters the accommodating chamber 201 through the air inlet end 202, thereby providing a stable airflow for the atomization component 4.

[0047] In this embodiment, a plurality of one-way devices 6 are further included, and the plurality of one-way devices 6 are arranged at each bifurcated section of the airflow pipeline 5, corresponding one to one with the plurality of air pumps 1. Specifically, the one-way devices 6 are respectively arranged at the bifurcated sections of the airflow pipeline 5, and when one of the air pumps 1 is working, the circuit board 8 controls the remaining air pumps 1 to be turned off, and the one-way device 6 of the working air pump 1 is turned on, and the airflow flows out along the airflow pipeline 5; at the same time, the airflow cannot enter the air pump 1 in the shutdown state through other one-way devices 6, effectively preventing the airflow from leaking and affecting the air pressure entering the atomizing assembly 4.

[0048] Furthermore, the one-way device 6 includes but is not limited to: a spring-loaded one-way valve, a duckbill valve, and a solenoid valve.

[0049] In this embodiment, a spoiler 7 is also included, and a spoiler is filled in the spoiler 7. A plurality of small holes are provided at the bottom of the spoiler 7, and a spoiler 7 is connected in front of the air inlet of each air pump 1. Preferably, the spoiler is made of a sponge with a loose and porous body. When the air pump 1 draws airflow, the external airflow first enters the spoiler 7 and then enters the air pump. The loose and porous spoiler makes the airflow smooth, which can effectively reduce the noise generated by the airflow, so as to give the user a better experience.

[0050] In this embodiment, a circuit board 8 is further provided at the bottom of the mounting base 2, and a detector for monitoring the working state of the air pump 1 is further provided on the circuit board 8. Specifically, in this embodiment, when the two air pumps work alternately, the circuit board 8 controls the circuit switch of the air pump 1 to make the two air pumps 1 work alternately, and the alternating manner includes but is not limited to the number of working times and the working time, so that the air pumps 1 can take turns to rest, and prevent the air pumps 1 from being damaged due to long-term operation.

[0051] Furthermore, the detector will monitor the current, resistance and other electrical control parameters of the air pump 1. Except that the current will increase at the moment when the air pump 1 is started, in the normal working state, the current, resistance and other electrical control parameters of the air pump 1 are in a constant state; when the detector detects that the current, resistance and other values ​​of the air pump 1 are abnormal, it is determined that the air pump 1 is damaged, and the detector feeds back the information to the circuit main board 8, and the circuit main board 8 marks the air pump 1 as damaged and no longer starts. The air pump 1 is an important component of the aroma diffuser, and it is also the component with the most serious consumption in the aroma diffuser. In the prior art, the aroma diffuser only contains one air pump 1, and the aroma diffuser often cannot be used due to the damage of the air pump 1. To solve this problem, the utility model provides a multi-air pump aroma diffuser. When other air pumps 1 are damaged, it is in a single air pump working state. The alternating working mode not only slows down the damage speed of the air pump 1, but also extends the service life of the aroma diffuser.

[0052] In this embodiment, a battery 12 for supplying electricity to the air pump 1 is also provided on the mounting base 2 to supply power to the air pump 1 to ensure that the air pump 1 can work stably and output a constant airflow.

[0053] In this embodiment, the atomizer assembly 4 also includes an atomizer core 10 and an atomizer chamber 11, and the atomizer core 10 is located at the bottom of the atomizer chamber 11; a first air flow channel 1101 provided at the bottom of the atomizer chamber 11 is connected to the air inlet end 202 and the atomizer core 10; specifically, a gap 9 is left between the outer wall of the atomizer chamber 11 and the inner wall of the accommodating chamber 201; the air flow of the air pump 1 first enters the accommodating chamber 201 from the air flow duct 5 through the air inlet end 202, and fills the gap 9 left between the accommodating chamber 201 and the outside of the atomizer chamber 11, and enters the atomizer assembly 4 through the first air flow channel 1101.

[0054] In this embodiment, an uneven noise reduction portion 1102 is further provided inside the atomizing chamber 11. Preferably, the noise reduction portion 1102 may be made of metal material, or a plastic material with an anti-corrosion material coated on the surface. The airflow sound collides with the inner wall of the atomizing chamber 11, hits the uneven noise reduction portion 1102 and is continuously reflected, consuming energy, thereby reducing noise. The user cannot hear the internal sound during use, and has a better experience.

[0055] Correspondingly, the atomizer core 10 is provided with a second air flow channel 1001, which is connected to the first air flow channel 1101, and the outlet diameter of the second air flow channel 1001 is much smaller than the diameter of the first air flow channel 1101. Since the air flow velocity remains unchanged, the air flow becomes a high-pressure air flow when entering the second air flow channel 1001 with a reduced diameter; correspondingly, the atomizer core 1001 is also provided with a second essential oil channel 1002, and the essential oil bottle 3 is provided with a first essential oil channel 301 leading to the bottom of the essential oil bottle 3, and the first essential oil channel 301 is connected to the second essential oil channel 1002; the outlet of the second essential oil channel 1002 is higher than the outlet of the second air flow channel 1001. According to the principle of the Venturi effect, low pressure will be generated near the high-speed flowing fluid, thereby producing an adsorption effect. When the high-pressure airflow flows out from the outlet of the second airflow channel 1001, it produces an adsorption effect on the second essential oil channel 1002, causing the essential oil in the essential oil bottle 3 to flow upward. The essential oil at the outlet of the second essential oil channel 1002 is broken up into micron-sized particles by the high-pressure airflow, and the essential oil is atomized and floats upward along the atomization chamber 10 out of the aroma diffuser.

[0056] Taking a fragrance diffuser with two air pumps 1 as an example, its working state is as follows: the battery 12 supplies power to the two air pumps 1 alternately, so that the air pumps 1 can output a stable airflow; when the fragrance diffuser is started, the circuit main board 8 first performs an electronic control parameter test to confirm whether each air pump 1 can work normally, and then selects the air pump 1 for this work according to the working state of the air pump 1 when the air pump 1 was last shut down. The other air pump 1 is in the shut-down state, and the airflow pressure of the working air pump 1 causes the one-way device 6 to open. At the same time, the one-way device 6 in front of the air pump 1 in the shut-down state prevents the airflow from entering the air pump 1 in the shut-down state, so as not to affect the air pressure of the airflow entering the atomizing component 4. Furthermore, the other end of the airflow duct 5 is connected to the air inlet end 202, and the airflow enters the accommodating chamber 201 through the air inlet end 202, and fills the gap 9 between the inner wall of the accommodating chamber 201 and the outer wall of the atomizing chamber 11, and enters the atomizing core 10 through the first airflow channel 1101. The second airflow channel 1001 of the atomizing core 10 converts the smoothly entering airflow into a high-pressure airflow, and breaks up the essential oil at the outlet of the second essential oil channel 1002, thereby atomizing the essential oil, and the atomized essential oil floats upward along the atomizing chamber 11 out of the aroma diffuser. In the prior art, the aroma diffuser contains only one air pump 1, and the aroma diffuser often cannot be used due to damage of the air pump 1. In the present embodiment, the two air pumps work alternately and are equipped with a detector. When one of the air pumps 1 is damaged, the aroma diffuser changes to a single air pump working state, effectively avoiding the situation where the entire aroma diffuser cannot be used due to damage of a single air pump 1. At the same time, the alternating working mode of the two air pumps slows down the damage speed of the air pump 1, prolongs the service life of the aroma diffuser, saves user costs, and has better effects.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
