The present disclosure will be further explained with reference to
Referring to
The external liquid bottle 1 is matched with the atomizing module 100 of the present disclosure in an inverted state to realize the atomization effect; if the liquid guide piece 3 is not provided, then the liquid will pour on the atomizing sheet 24 intensively and quickly under the action of gravity, and this will result in excessive essential oil covering on the atomizing sheet 24, thereby affecting the atomization effect; or this even results in excessive filling of essential oil in the atomizing cavity 23 such that the atomizing sheet 24 cannot perform atomization. After the liquid guide piece 3 is added, the dropping speed of liquid can be slowed down, and when there is too much liquid, the liquid can be controlled not to drop, thereby ensuring the best atomization effect in the whole atomization process.
In some embodiments, the liquid guide piece 3 includes a liquid guiding section 31 and a siphon section 32, the liquid guiding section 31 defines a liquid guiding through hole 311, the siphon section 32 defines a siphon groove 321, the siphon groove 321 is in communication with the liquid guiding through hole 311, the siphon section 32 abuts against the atomizing sheet 24, the siphon groove 321 faces the atomizing sheet 24, and when the liquid fully fills the siphon groove 321, the liquid in the liquid bottle 1 stops dropping.
When the liquid fully fills the siphon groove 321, there is no air between the siphon groove 321 and the liquid guiding through hole 311, and the liquid in the liquid buffering cavity 213 stops dropping onto the siphon groove 321 and the atomizing sheet 24; the atomizing sheet 24 can atomize the liquid normally under the conductive state, and when some liquid is atomized until the siphon groove 321 is not fully filled with the liquid, air will continue to flow into the space between the siphon groove 321 and the liquid guiding through hole 311, and the liquid in the liquid buffering cavity 213 will continue to drop onto the siphon groove 321 and the atomizing sheet 24 through the liquid guiding through hole 311. Therefore, through the ingenious design of mechanical structure, whether the liquid drops or not can be controlled.
In some embodiments, the siphon groove 321 has an arc-shaped cross section, the atomizing sheet 24 has a circular cross section, and the center position of the siphon groove 321 in the width direction is 2 to 10 mm away from the center position of the atomizing sheet 24.
By adopting the above technical solution, the optimal atomization area of the atomizing sheet 24 is generally the central area, and the liquid drops preferentially from the relatively central position in the siphon groove 321 through the liquid guiding through hole 311; if the centers of the siphon groove 321 and the atomizing sheet 24 are overlapped, then the atomization effect of the atomizing sheet 24 will be affected when the liquid drops, while the arrangement of the eccentric structure can effectively avoid the interference of liquid dropping with the atomization effect and achieve the optimal atomization effect.
In some embodiments, the atomizing module 100 further includes a first sealing ring 15, which is arranged at the joint of the liquid guide piece 3 and the buffering part 212, so as to prevent the liquid from leaking from the joint of the liquid guide piece 3 and the buffering part 212.
The atomizing module 100 further includes a second sealing ring 5 which is arranged on the mounting part 211, and the second sealing ring 5 is used for sealing the joint of the mounting part 211 and the external liquid bottle 1 when the mounting part 211 is connected with the external liquid bottle 1.
By adopting the above technical solution, the liquid guide piece 3 achieves the communication or isolation between the buffering part 212 and the atomizing cavity 213, the first sealing ring 15 prevents the liquid from leaking between the liquid guide piece 3 and the buffering part 212, and the second sealing ring 5 prevents the liquid from leaking between the mounting part 211 and the external liquid bottle 1, thereby ensuring the tightness of the atomizing module 100.
In some embodiments, the liquid guide piece 3 is made of a porous ceramic material or oil-conducting cotton or foamed silica gel or fiber.
By adopting the above technical solution, the dropping speed of liquid onto the atomizing sheet 24 can be slowed down more effectively.
In some embodiments, the atomizing housing 2 includes an upper atomizing housing 21 and a lower atomizing housing 22 which are detachably connected with each other, wherein the mounting part 211, the buffering part 212, the air inlet channel 4 and the mist outlet 43 are all arranged in the upper atomizing housing 211, and the atomizing cavity 23 and the atomizing sheet 24 are all arranged in the lower atomizing housing 22.
By adopting the above technical solution, the upper atomizing housing 21 and the lower atomizing housing 22 are detachably connected with each other, which is convenient for users to disassemble and clean the surface of the atomizing sheet 24 inside the lower atomizing housing 22, so as to prevent dirt generated by some liquid from affecting the atomization effect, or to prevent residual original liquid from affecting the atomization purity of the current liquid when the liquid to be atomized is changed.
In some embodiments, the atomizing module 100 further includes a blocking member 6, the blocking member 6 is located in the atomizing cavity 23 and close to the air inlet channel 4 and the mist outlet 43, and it is used for blocking large droplets of liquid.
By adopting the above technical solution, the large droplets of liquid that are not completely atomized are attached to the blocking member 6, and they can continue to fall back to the atomizing sheet 24 to be atomized again, thereby improving the atomization effect. In addition, it is also possible to avoid the accumulation of large droplets of liquid that are not completely atomized around the mist outlet 43, which otherwise would affect the mist releasing effect and the user experience.
In some embodiments, the air inlet channel 4 includes an air inlet 41 and an air outlet 42, and the atomizing module 100 further includes an airflow direction guide piece 7 which is arranged in the upper atomizing housing 21, the air inlet 41 and the air outlet 42 are respectively located on both sides of the guide piece 7, and the guide piece 7 is used for guiding the airflow from the air inlet 41 to the air outlet 42 to be released. Under the use state, the level of the air inlet 41 is higher than that of the air outlet 42, and the external airflow enters the air inlet channel 4 through the air inlet 41, and then flows to the atomizing cavity 23 through the air outlet 42.
By adopting the above technical solution, the flow direction of the airflow can be controlled, such that the airflow circulates for a full circle in the atomizing cavity 23 to drive atomized liquid micro-particles to be sent out from the mist outlet 43, thereby preventing the non-atomized liquid from colliding with the atomized liquid and achieving a better atomization effect.
The atomizing module 100 is especially suitable for the atomization of viscous liquid like pure essential oils, and such viscous liquid can form a liquid film on the surface of the atomizing sheet 24, such that the atomization efficiency of liquid is higher, and the atomization speed and atomization amount can be well controlled to avoid the waste of the liquid to be atomized.
Specifically, the upper atomizing housing 21 is provided with the mounting part 211 connected with the external liquid bottle 1, the mounting part 211 is provided with the second sealing ring 5, and when the mounting part 211 is connected with the external liquid bottle 1, the second sealing ring 5 seals the joint of the mounting part 211 and the external liquid bottle 1, so as to prevent liquid leakage at the joint of the external liquid bottle 1 and the mounting part 211 when liquid drops. The mounting part 211 may be connected with the external liquid bottle 1 through screw connection, snap connection, transition fit or the like.
The mounting part 211 is connected with the buffering part 212, the buffering part 212 defines a liquid buffering cavity 213 which is in communication with the external liquid bottle 1, and the liquid buffering cavity 213 has a funnel-shaped structure, that is, the opening of the external liquid bottle 1 is larger than the outlet of the liquid buffering cavity 213.
The lower atomizing housing 22 is provided therein with the atomizing cavity 23 and the atomizing sheet 24, the buffering part 212 extends into the atomizing cavity 23, the atomizing sheet 24 is located below the buffering part 212, and the liquid guide piece 3 is arranged on one side of the buffering part 212 facing the atomizing sheet 24.
To more effectively slow down the dropping speed of liquid onto the atomizing sheet 24, the liquid guide piece 3 may be made of a porous ceramic material, oil-conducting cotton, foamed silica gel or fiber, and the internal pore size, the number of pores, the shape of the porous structure or the like of the liquid guide piece 3 may be set as required according to the atomization requirements.
In order to make it convenient for the user to disassemble and clean the surface of the atomizing sheet 24 inside the lower atomizing housing 22 so as to prevent the dirt generated by some liquid from affecting the atomization effect, or to prevent the residual original liquid from affecting the atomization purity of the current liquid when the liquid to be atomized is changed, in this embodiment, the atomizing housing 2 includes the upper atomizing housing 21 and the lower atomizing housing 22 that are detachable, and the upper atomizing housing 21 and the lower atomizing housing 22 may be connected by screw connection, and of course, they may also be connected by snap connection or plugging connection.
It should be noted that, in some other embodiments, the atomizing housing 2 may also be integrally formed.
The liquid guide piece 3 includes a liquid guiding section 31 and a siphon section 32, wherein the liquid guiding section 31 defines a liquid guiding through hole 311, the siphon section 32 defines a siphon groove 321, and the siphon groove 321 is in communication with the liquid guiding through hole 311. The cross-sectional area of the liquid guiding through hole 311 should be less than 2.0 mm2, and the liquid guiding through hole 311 is mainly used for ventilation in the liquid guiding process; if the area is too large, it is likely for the liquid to quickly drop on the atomizing sheet 24, which tends to cause liquid waste. The distance between one side of the siphon section 32 that is close to the atomizing sheet 24 and the atomizing sheet 24 is H1, which should be controlled at 0 to 0.5 mm, and the depth of the siphon groove 321 is H2, which should be controlled at 0.3 to 1.5 mm. In addition, the siphon groove 321 has an arc-shaped cross-section and the atomizing sheet 24 has a circular cross-section, and the distance between the center position of the siphon groove 321 in the width direction and the center position of the atomizing sheet 24 is L, which is 2 to 10 mm.
When the liquid fully fills the siphon groove 321, the liquid in the liquid bottle 1 stops dropping, and when the liquid fully fills the siphon groove 321, there is no air between the siphon groove 321 and the liquid guiding through hole 311, and the liquid in the liquid buffering cavity 213 stops dropping onto the siphon groove 321 and the atomizing sheet 24; the atomizing sheet 24 can atomize the liquid normally under the conductive state, and when some liquid is atomized until the siphon groove 321 is not fully filled with the liquid, air will continue to flow into the space between the siphon groove 321 and the liquid guiding through hole 311, and the liquid in the liquid buffering cavity 213 will continue to drop onto the siphon groove 321 and the atomizing sheet 24 through the liquid guiding through hole 311. Therefore, through the ingenious design of mechanical structure, whether the liquid drops or not can be controlled. If the siphon groove 321 is too small, a small amount of liquid will fully fill the whole siphon groove 321, and the amount of the liquid may even be insufficient for one time of atomization of the smallest unit for the atomization sheet 24; if the siphon groove 321 is too large, more liquid will be needed in order to prevent the liquid from continuously dropping, and the liquid may overflow the atomizing sheet 24 to affect the whole atomization work. As such, the selection of H1 and H2 in the present disclosure can prevent both insufficient and excessive dropping of the liquid. In addition, since the position of the atomizing sheet 24 with the best atomization effect is located at the center of the atomizing sheet 24, the position at which oil is guided from the porous ceramic to the atomizing sheet 24 is deliberately set to deviate from the center of the atomizing sheet 24 by a deviation distance of L, so as to prevent the atomization effect from being affected by covering the best atomization position of the atomizing sheet 24.
The joint between the liquid guide piece 3 and the buffering part 212 is provided with the first sealing ring 15 to prevent liquid leakage at the joint, and the first sealing ring 15 can prevent the liquid from leaking between the liquid guide piece 3 and the buffering part 212 and ensure the tightness of the atomizing module 100.
The upper atomizing housing 21 further defines an air inlet channel 4 which includes an air inlet 41 and an air outlet 42, wherein the air inlet 41 is used to be connected with an external ventilation device, and the air outlet 42 is used for communication with the atomizing cavity 23.
The upper atomizing housing 21 further defines a mist outlet 43 that is in communication with the atomizing cavity 23, and the mist outlet 43 is not directly in communication with the air inlet 41.
The airflow direction guide piece 6 guides the airflow from the air inlet 41 to the air outlet 42 to be released, the level of the air inlet 41 relative to the horizon is higher than the level of the air outlet 42, the air inlet 41 and the air outlet 42 are respectively located on both sides of the airflow direction guide piece 6, and the airflow direction guide piece 6 guides the airflow to flow in the designated circumferential direction within the air inlet channel 4, such that the airflow circulates for a full circle in the atomizing cavity 23 to drive atomized liquid micro-particles to be sent out from the mist outlet 43, thereby preventing the non-atomized liquid from colliding with the atomized liquid and achieving a better atomization effect, and further preventing the backflow of mist or liquid.
The upper atomizing housing 21 is provided therein with a blocking member 7 which has a generally umbrella-like structure, the blocking member 7 is fixedly sleeved on the buffering part 212 and is located in the atomizing cavity 23 near the air inlet channel 4 and the mist outlet 43, and it is mainly used for blocking large droplets of liquid that are not completely atomized.
Working principle is described as follows:
The external liquid bottle 1 is screwed on the upper atomizing housing 21 upside down, and a second sealing ring 5 is arranged at the joint between the external liquid bottle 1 and the upper atomizing housing 21 to prevent the liquid of the external liquid bottle 1 from leaking from the joint therebetween.
Under the action of gravity, the liquid in the external liquid bottle 1 passes through the liquid buffering cavity 213, the liquid guiding section 31 and the siphon section 32, and the first sealing ring 15 is arranged at the joint between the liquid guide piece 3 and the buffering part 212 to prevent the liquid from leaking from the joint therebetween, and thus liquid leakage between the liquid guide piece 3 and the buffering part 212 can be prevented.
The liquid to be atomized drops from the siphon groove 321 onto the atomizing sheet 24, and the atomizing sheet 24 can normally atomize the liquid under the conductive state; when the siphon groove 321 is not fully filled with the liquid to be atomized, air will continue to flow into the space between the siphon groove 321 and the liquid guiding through hole 311, and the liquid in the liquid buffering cavity 213 will continue to drop onto the siphon groove 321 and the atomizing sheet 24 through the liquid guiding through hole 311; when the liquid to be atomized fully fills the siphon groove 321, there is no air between the siphon groove 321 and the liquid guiding through hole 311, and the liquid stops dropping; if the atomizing sheet 24 is still in the conductive state, the atomization will be continued; and if the atomizing sheet 24 is not powered, the whole liquid will not drop again, and thus there is no need to worry that the liquid in the inverted external liquid bottle 1 will overflow the atomizing sheet 24.
The airflow direction guide piece 6 guides the airflow to flow in the designated circumferential direction within the air inlet channel 4, such that the airflow circulates for a full circle in the atomizing cavity 23 to drive the atomized liquid and send it out from the mist outlet 43; and the blocking member 7 is located in the atomizing cavity 23 near the air inlet channel 4 and the mist outlet 43, and is used to block the large droplets of liquid that are not completely atomized.
In some other embodiments, the liquid guide piece 3 may also be provided with a floating sealing structure at one side close to the atomizing sheet 24; that is, when the liquid drops excessively, a floating ball floats to block the liquid guiding through hole 311 to achieve the effect of preventing the liquid from continuing to drop.
Referring to
By adopting the above technical solution, the atomizing module 100 of the present disclosure is especially suitable for the atomization of pure essential oil; since pure essential oils is a liquid with higher viscosity, only a thin layer of essential oil can be covered on the surface of the atomizing sheet 24 during atomization, so it is especially necessary to control the dropping speed and droplet size of essential oil; therefore, the atomization effect can be optimally realized by the cooperation of the atomizing module 100 and the fragrance diffuser 200.
