[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] The present application first proposes an aromatherapy device, which includes a first shell 10 and a second shell 20. The first shell 10 forms at least a portion of a liquid storage chamber 01 and a volatilization chamber 02. The liquid storage chamber 01 and the volatilization chamber 02 are connected through a microporous structure to guide the essential oil in the liquid storage chamber 01 to the volatilization chamber 02 for volatilization; the first shell 10 is also provided with a first air inlet 03 and a first air outlet 04 connected to the volatilization chamber 02; the second shell 20 forms a first accommodating chamber and a second air inlet 05 and a second air outlet 06 connected to the first accommodating chamber; the first shell 10 is arranged in the first accommodating chamber, and the first air inlet 03 is connected to the second air inlet 05; the outer wall of the first shell 10 is spaced apart from the inner wall of the first accommodating chamber to form a first flow channel 07 connected to the second air outlet 06, and the first air outlet 04 is connected to the first flow channel 07.

[0024] Specifically, the airflow enters the first containing chamber through the second air inlet 05, then enters the volatilization chamber 02 through the first air inlet 03, mixes with the volatilized essential oil in the volatilization chamber 02, flows out of the volatilization chamber 02 through the first air outlet 04 and enters the first flow channel 07, and the airflow flows to the second air outlet 06 through the first flow channel 07, and then flows out to the external space.

[0025] The liquid storage chamber 01 is connected with the volatilization chamber 02 through a microporous structure, which is convenient for guiding the essential oil in the liquid storage chamber 01 to the volatilization chamber 02 for volatilization; the second shell 20 forms a first accommodating chamber and a second air inlet 05 and a second air outlet 06 connected to the first accommodating chamber. The first shell 10 is arranged in the first accommodating chamber, which is convenient for reducing the interference of the external environment on the first shell 10 and improving reliability; the first air inlet 03 is connected with the second air inlet 05, and the outer wall of the first shell 10 is spaced from the inner wall of the first accommodating chamber to form a first flow channel 07 connected with the second air outlet 06, which can enable the airflow to enter the first accommodating chamber through the second air inlet 05, and then enter the volatilization chamber 02 through the first air inlet 03, so that the airflow can flow to the second air outlet 06 through the gap between the outer wall of the first shell 10 and the inner wall of the first accommodating chamber, which can reduce the risk of the essential oil in the volatilization chamber 02 directly contacting the external environment and the risk of the essential oil being oxidized and deteriorated.

[0026] Optionally, the second air outlet 06 is located on a side of the first shell 10 where the liquid storage chamber 01 is provided, the first air inlet 03 is located on a side of the first shell 10 away from the liquid storage chamber 01 , and the second air inlet 05 is located on a side of the second shell 20 away from the liquid storage chamber 01 .

[0027] The second air outlet is located on the side of the first shell 10 where the liquid storage chamber 01 is provided, so that the airflow can flow from the side of the second shell 20 away from the liquid storage chamber 01 to the side of the first shell 10 away from the liquid storage chamber 01, and then flow to the side of the first shell 10 where the liquid storage chamber 01 is provided, and then flow out to the external environment. This can increase the length of the gas flow channel, reduce the risk of direct contact between the volatilization chamber 02 and the external environment, and further reduce the risk of oxidation and deterioration of the essential oil.

[0028] Alternatively, if Figure 1 and Figure 3 As shown, the first shell 10 includes a liquid guiding member 11 and a support member 12. The liquid guiding member 11 forms a volatilization chamber 02, a first air inlet 03 and a third air outlet 08 connected to the volatilization chamber 02; the upper end portion of the support member 12 forms at least a portion of the liquid storage chamber 01, and the lower end portion of the support member 12 forms a first installation chamber, and the liquid guiding member 11 is arranged in the first installation chamber; the support member 12 is provided with a first air outlet 04 connected to the third air outlet 08.

[0029] The liquid guide 11 forms the first air inlet 03, the third air outlet 08, and the volatilization chamber 02. The airflow enters the volatilization chamber 02 through the first air inlet 03, then flows out of the volatilization chamber 02 through the third air outlet 08, and then enters the first flow channel 07 through the first air outlet 04. The upper end of the support member 12 forms at least part of the liquid storage chamber 01, and the lower end forms the first installation chamber. The liquid guide 11 is arranged in the first installation chamber, which has a simple structure, is easy to assemble, and is convenient for sealing the liquid storage chamber 01; the first air outlet 04 is used to connect the third air outlet 08 and the first flow channel 07, and can be arranged on the side wall of the support member 12, and is not specifically limited.

[0030] Optionally, the aromatherapy device further includes a first heating body 40, which is at least partially accommodated in the volatilization chamber 02, and the inner wall of the volatilization chamber 02 forms a volatilization surface. The liquid guide 11 can transport the oil in the oil storage chamber to the volatilization surface. The heating area and the volatilization surface are arranged at intervals. The first heating body 40 generates heat as a whole, and the heat radiated from the outer peripheral surface of the first heating body 40 heats the oil, so that the oil evaporates from the volatilization surface. The arrangement of the liquid guide 11 and the first heating body 40 is not limited to the above-mentioned manner. For example, the liquid guide 11 can also be arranged relative to the first heating body 40 up and down, and the liquid guide 11 can be provided with an arc groove extending in the horizontal direction, the opening of the arc groove faces the heating area, and the arc groove is semi-enclosed around the periphery of the heating area. The first heating body 40 generates heat as a whole, forming a three-dimensional heating in space, and radiating heat to the groove wall of the arc groove to volatilize and diffuse the oil.

[0031] Alternatively, if Figure 3As shown, the support member 12 includes a partition 122 and a support member 121. The partition is provided with a through hole 123, and the liquid guiding member 11 is provided with a microporous structure to connect the through hole 123 and the volatilization chamber 02; the partition 122 is arranged in the support member 121, and the internal space of the support member 121 is divided into a liquid storage chamber 01 and a first installation chamber; the first air outlet 04 is formed in the support member 12 and is located on a side close to the partition 122, and the liquid guiding member 11 and the partition 122 are spaced apart to connect the first air outlet 04.

[0032] The microporous structure on the liquid guiding member 11 can utilize the surface tension of the oil to achieve a liquid locking effect, thereby reducing the risk of liquid diffused to the volatile surface directly flowing out of the liquid storage chamber 01 and into the volatile chamber 02 and causing leakage; the partition portion facilitates dividing the internal space of the support portion 121 into the liquid storage chamber 01 and the first installation chamber, thereby facilitating sealing the liquid storage chamber 01; the liquid guiding member 11 is provided with a microporous structure to connect the through hole 123 and the volatile chamber 02, thereby facilitating the formation of a volatile surface and the realization of liquid guiding, thereby facilitating the evaporation of the oil from the volatile surface; the liquid guiding member 11 and the partition portion 122 are spaced apart, thereby facilitating the connection between the first air outlet 04 and the third air outlet 08.

[0033] Optionally, the first air outlet 04 is used to connect the third air outlet 08 and the first flow channel 07 , and may be disposed on a side wall of the support portion 121 , without specific limitation.

[0034] Optionally, the first shell 10 also includes a base 30, and the side wall of the base 30 is arranged close to the side of the second shell 20 and is spaced from the inner wall of the first accommodating cavity to form a first flow channel 07; the liquid guiding member 11 and the supporting member 12 are arranged in the base 30, and the bottom wall of the base 30 is provided with a third air inlet 09 connected to the first air inlet 03, and the side wall of the base 30 is provided with a fourth air outlet 010 connected to the first flow channel 07 and the first air outlet 04.

[0035] The side wall of the base 30 close to the second shell 20 is spaced apart from the inner wall of the first accommodating chamber to form the first flow channel 07, so that the airflow can flow out to the second air outlet 06 through the space between the side wall of the base 30 close to the second shell 20 and the inner wall of the first accommodating chamber, thereby reducing the risk of direct contact between the essential oil in the volatilization chamber 02 and the external environment; the setting of the third air inlet 09 facilitates the airflow to enter the volatilization chamber 02 in the base 30 through the second air inlet 05 and the third air inlet 09, and the setting of the fourth air outlet 010 facilitates the airflow flowing out of the first air outlet 04 to the first flow channel 07; the liquid guiding member 11 and the support member 12 are arranged in the base 30, so that the volatilization chamber 02 is arranged in the base 30, thereby reducing the risk of direct contact between the essential oil in the volatilization chamber 02 and the external environment, and improving the anti-interference ability of the liquid guiding member 11 and the support member 12.

[0036] Optionally, the base 30 forms a second installation cavity, and the liquid guide member 11 and the support member 12 are disposed in the second installation cavity. In other embodiments, the support member 12 and the base 30 may be integrally disposed, which is not specifically limited.

[0037] Optionally, the first heating body 40 is fixed on the base 30 to improve the position stability of the first heating body 40 .

[0038] Optionally, the aromatherapy device also includes a third shell 50, which is sealed and connected to the first shell 10 to form a liquid storage chamber 01; the third shell 50 is at least partially located in the first accommodating chamber, and the outer wall of the third shell 50 is spaced apart from the inner wall of the first accommodating chamber to form an extended flow channel 011, which is respectively connected to the first flow channel 07 and the external environment.

[0039] The third shell 50 is sealed and connected to the first shell 10, so as to improve the sealing performance of the liquid storage chamber 01 and reduce the risk of oxidation of the liquid in the liquid storage chamber 01; the third shell 50 is at least partially located in the first accommodating chamber formed by the second shell 20, so as to improve the position stability of the third shell 50; the outer wall of the third shell 50 is spaced apart from the inner wall of the first accommodating chamber to form an extended flow channel 011, so as to guide the airflow flowing out of the first flow channel 07 to the external environment, which can further increase the flow channel length of the airflow and reduce the risk of direct contact between the essential oil in the volatilization chamber 02 and the external environment.

[0040] In other embodiments, the third shell 50 may be integrally formed with the support member 12 , or the support member 12 may independently form the liquid storage chamber 01 , which is not specifically limited.

[0041] Alternatively, if Figure 1 As shown, the aromatherapy device further includes an air supply component 80 , an air inlet of the air supply component 80 is connected to the second air inlet 05 , and an air outlet of the air supply component 80 is connected to the first air inlet 03 .

[0042] The arrangement of the air supply assembly 80 can provide power for the convection of the airflow, increase the airflow velocity, improve the controllability of the airflow velocity in the aromatherapy device, and improve the atomization effect of the aromatherapy device.

[0043] Optionally, the air supply component 80 serves as an active air supply system to transport the airflow sucked into the aromatherapy device from the second air inlet 05 to the first air inlet 03. The airflow enters the volatilization chamber 02 from the first air inlet 03. The oil on the volatilization surface in the volatilization chamber 02 is volatilized and atomized due to thermal radiation and mixed with the airflow. The mixed airflow flows out to the external space through the first flow channel 07 and the second air outlet 06 to achieve fragrance diffusion.

[0044] Optionally, the air supply component 80 includes a piezoelectric diaphragm pump or an axial flow fan.

[0045] In an application scenario, such as Figures 5 to 8 As shown, the air supply assembly 80 includes a diaphragm pump, which includes a pump housing 131 and a first diaphragm 132. The diaphragm pump is a pump housing 131 in which a first diaphragm 132 is arranged. The first diaphragm 132 achieves up and down vibrations through pistons, pneumatics, hydraulics, etc., forming a negative pressure area in the shell of the pump housing 131. Due to the pressure difference, the external gas continuously enters the shell of the pump housing 131, and the narrow airflow channel inside will further accelerate the gas flow rate, thereby achieving forced flow of the gas; further, the diaphragm pump also includes a power cord. The startup noise of the diaphragm pump is within 30dB within a range of 0.5m, and the airflow rate is ≥1L / min; it can further reduce the noise of the aromatherapy device when it is working, and achieve a better atomization effect.

[0046] Optionally, the diaphragm pump is a piezoelectric diaphragm pump, which can use piezoelectric ceramics to agitate the diaphragm. The vibration of the piezoelectric element is used to agitate the diaphragm, changing the volume of the pump chamber, thereby sucking in / exhausting air. For example, in an application scenario, such as Figure 7 , Figure 8 As shown, the air supply assembly 80 includes an air supply housing 133, a second diaphragm 134, and a piezoelectric ceramic 135. The second diaphragm 134 is provided on the upper side of the piezoelectric ceramic 135. When the piezoelectric ceramic 135 is powered on, the high-frequency vibration of the upper and lower amplitudes of the piezoelectric ceramic 135 drives the upper and lower amplitudes of the vibration of the second diaphragm 134, forming a negative pressure area in the housing of the air supply housing 133. Due to the pressure difference, the external gas continues to enter the housing of the air supply housing 133. The narrow air flow channel inside will further accelerate the gas flow rate, thereby realizing forced convection of the gas. Its overall size is small and thin, and it can achieve high pressure and high flow. Its ultrasonic vibration principle can achieve an ultra-quiet effect. At the same time, its high-frequency vibration to discharge the gas can make the outflowing gas more continuous and pulsating. In an application scenario, the structure also includes components such as a power cord; the startup noise is within 30dB within a range of 0.5m, and the air flow rate is ≥1L / min; it can further reduce the noise of the aromatherapy device when it is working, and achieve a better atomization effect.

[0047] In other embodiments, Fig. 9 As shown, the air supply assembly 80 includes an axial flow fan. In an application scenario, the axial flow fan mainly includes a fan housing 136, a bracket 137, a fan blade 138, a motor 139, a power cord 1310 and other components. The axial flow fan relies on the high-speed rotation of the fan blade 138 to drive the air flow to enter from the air inlet side of the axial flow fan and flow out from the air outlet side of the axial flow fan. The speed of the axial flow fan is within the range of 5000 to 20000 rpm, the aerodynamic noise is within 30 dB within 0.5 m, and the air flow rate is ≥1 L / min, which can further reduce the noise of the aromatherapy device when it is working and achieve a better atomization effect.

[0048] Alternatively, if Figure 4 As shown, in one application scenario, the aromatherapy device further includes a second heating body 70 , which is disposed on the inner wall of the volatilization chamber 02 .

[0049] The second heating body 70 is arranged on the inner wall of the volatilization chamber 02, and the inner wall of the volatilization chamber 02 forms a volatilization surface. The second heating body 70 generates heat as a whole, and the heat radiated by it is convenient to directly heat the oil at the volatilization surface, so that the oil evaporates from the volatilization surface, which can improve the volatilization effect; and the second heating body 70 is arranged on the inner wall of the volatilization chamber 02, which can reduce the space occupied by the heating body of the aromatherapy device in the volatilization chamber 02, thereby improving the volatilization effect.

[0050] Optionally, the aromatherapy device also includes a battery compartment 60; the second shell 20 includes a bottom plate 21, the bottom plate 21 covers an opening at one end of the first accommodating cavity to form a second air inlet 05, and the other end of the first accommodating cavity opens as a second air outlet 06; the battery compartment 60 is spaced apart from the second shell 20 to form a second flow channel 012 connected to the second air inlet 05 and the first air inlet 03.

[0051] The battery compartment 60 can provide electrical energy for the aromatherapy device to improve portability; optionally, in an application scenario, the battery compartment 60 is arranged in the first accommodating chamber, which can improve the aesthetics of the atomizer and protect the battery from interference from external factors; the bottom plate 21 covers an opening at one end of the first accommodating chamber to facilitate the formation of a second air inlet 05, and the structure is simple; the other end opening of the first accommodating chamber serves as a second air outlet 06, which facilitates the airflow to flow through the volatilization chamber 02 in the first accommodating chamber, facilitates increasing the flow path length of the airflow, and reduces the risk of direct contact between the essential oil in the volatilization chamber 02 and the external environment; the battery compartment 60 and the second shell 20 are arranged at intervals to facilitate the formation of a second flow channel 012 connecting the second air inlet 05 and the first air inlet 03, so that the airflow enters the second flow channel 012 via the second air inlet 05, and then enters the first air inlet 03 through the second flow channel 012.

[0052] Optionally, in an application scenario, the air supply component 80 is disposed on a side of the battery compartment 60 close to the first housing 10, and the air inlet of the air supply component 80 is connected to the second flow channel 012. The airflow can flow through the second flow channel 012, the air inlet of the air supply component 80, the air outlet of the air supply component 80, the third air inlet 09, the first air inlet 03 in sequence to enter the volatilization chamber 02, and then flow through the third air outlet 08, the first air outlet 04, the first flow channel 07, and the second air outlet 06 in sequence to flow out to the external space.

[0053] Optionally, the liquid guiding member 11 is an integrated composite ceramic body, and a volatile surface is provided on the side wall of the volatile chamber 02. The microporous structure on the liquid guiding member 11 can utilize the surface tension of the liquid to achieve a liquid locking effect, thereby reducing the risk of liquid diffusion to the volatile surface directly flowing out of the liquid storage chamber 01 and entering the volatile chamber 02 and causing leakage, and facilitates the thermal radiation effect of the second heating body 70 or the first heating body 40 on the oil at the volatile surface, thereby improving the volatile atomization effect of the liquid here.

[0054] Optionally, the microporous structure of the liquid guide 11 is provided with a plurality of capillary pores, and the pore size of the capillary pores is 5-50 μm (for example, 5 μm, 8 μm, 21.5 μm, 33 μm, 33.05 μm, 39 μm, 40 μm, 42 μm, 45 μm, 50 μm, etc.).

[0055] The microporous structure is provided with a plurality of capillary pores, which refer to micropores with a diameter in the micron level, and the pore size of the capillary pores is 5-50μm. The capillary force of the capillary pores can better achieve the liquid guiding and locking effect, reduce the risk of the oil flowing directly into the volatilization chamber 02 without being atomized, improve the atomization effect, and can reduce the influence of the capillary pores being too large on the liquid guiding speed and the liquid locking effect, and can reduce the influence of the capillary pores being too small on the liquid guiding effect.

[0056] Optionally, the microporous structure is provided with a plurality of capillary pores, and the pore spacing between the plurality of capillary pores is 10-100 μm (e.g., 10 μm, 19 μm, 26.5 μm, 38 μm, 53.7 μm, 69 μm, 72 μm, 88 μm, 95 μm, 100 μm, etc.). The microporous structure is a microporous ceramic structure, and the median pore size of the microporous ceramic is 5-50 μm (e.g., 5 μm, 9 μm, 13.7 μm, 29 μm, 32 μm, 38 μm, 45 μm, 50 μm, etc.), and the porosity is 30%-60%, which can achieve better atomization effect, reduce the risk of atomization being too fast or too slow and affecting the user experience, and can reduce the influence of the overly dense distribution of capillary pores on the structural stability, liquid guide speed and atomization speed of the liquid guide 11, and can reduce the influence of the overly sparse distribution of capillary pores on the atomization effect.

[0057] If the porosity is less than 30%, the supply rate of the essential oil will be limited, and it is difficult to meet the volatilization rate requirement of the volatilization surface; if the porosity is greater than 60%, the local strength of the liquid guide 11 will be reduced, and the location where the liquid guide 11 is set will easily cause powder to fall off. Specifically, the porosity of the liquid guide portion 111 can be 30%, 35%, 40%, 45%, 50%, 55%, 57%, etc.

[0058] Optionally, the second heating body 70 and the liquid guiding member 11 are integrally formed, which can reduce the number of parts of the aromatherapy device and facilitate assembly.

[0059] Alternatively, if Figure 2 As shown, the first shell 10 also includes a first magnetic component 101, which is arranged on the side of the base 30 away from the liquid storage chamber 01, and the second shell 20 includes a second magnetic component 102. The first shell 10 and the second shell 20 are detachably connected through the first magnetic component 101 and the second magnetic component 102. Specifically, the base 30 is fixedly connected to the second shell 20 through the first magnetic component 101.

[0060] Alternatively, if Figure 4 As shown, the liquid guide 11 includes a heater pin 71 electrically connected to the second heater 70. In an application scenario, the first magnetic member 101 and the second magnetic member 102 are both electrode pins, the heater pin 71 is electrically connected to the first magnetic member 101, and is electrically connected to the battery compartment 60 through the first magnetic member 101 and the second magnetic member 102. This arrangement facilitates power supply to the second heater 70.
