It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The terms "upper", "lower", "left", "right", "inner", "outer" and the like as used herein are for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 3, the present embodiment provides an ultrasonic atomizing device 100 including a mouthpiece 10, an ultrasonic atomizing assembly 20, and a power supply assembly 30.

As will be understood in conjunction with fig. 4-5, the mouthpiece 10 and the ultrasonic atomization assembly 20 form an ultrasonic atomizer and are removably connected. The mouthpiece 10 includes a body 10a, an outer connecting portion 10b, and an inner connecting portion 10 c.

The body 10a is exposed outside the ultrasonic atomization assembly 20. The body 10a is hollow inside and has an air intake hole 10a1 and a mouth end 10a 2. The number of the air intake holes 10a1 may be one or more. Through the mouth end 10a2, a user can inhale the liquid mist atomized by the ultrasonic atomizing assembly 20.

The outer connecting portion 10b and the inner connecting portion 10c both extend from the body 10a toward a direction away from the body 10a, and are both at least partially housed in the first chamber a of the ultrasonic atomizing assembly 20. The shapes of the outer connecting part 10b and the inner connecting part 10c match the shape of the first chamber a, and in a preferred implementation, the outer connecting part 10b and the inner connecting part 10c are approximately cylindrical; the body 10a extends from the outer connecting portion 10b or the inner connecting portion 10c toward the mouth end 10a2, and the opening area thereof gradually decreases and then remains substantially the same; the open shape of the mouth end 10a2 is generally oval to facilitate ingestion by a user.

The outer wall of the outer connecting part 10b is provided with a limiting groove 10b1, and the ultrasonic atomization assembly 20 is provided with a lug 22 c; the external connection portion 10b is held in the first chamber a by the engagement of the stopper groove 10b1 with the projection 22 c. During assembly, the outer connecting part 10b is placed in the first cavity A, the limiting groove 10b1 and the lug 22c are dislocated, and then the suction nozzle 10 is rotated, so that the lug 22c is buckled in the limiting groove 10b 1; and the reverse can be realized when the device is disassembled. The outer wall of the outer connecting portion 10b further has a sealing groove 10b2, and the sealing groove 10b2 is used for accommodating at least a part of a sealing ring (not shown in the figure) so as to seal the gap between the outer wall of the outer connecting portion 10b and the upper cover 22 when the outer connecting portion 10b is accommodated in the first chamber a of the ultrasonic atomizing assembly 20. The outer connecting portion 10b further has a cutaway groove 10b3 formed by recessing the end of the outer connecting portion 10 b.

The inner connecting portion 10c and the outer connecting portion 10b are spaced apart to form a third air flow passage 10 d; the third air flow passage 10d extends along the circumferential direction of the inner connecting portion 10c or the outer connecting portion 10b of the cylindrical shape; the inner connection portion 10c has a notch groove 10c1 formed by recessing the end of the inner connection portion 10 c. The intake hole 10a1 and the third air flow passage 10d constitute an intake passage. Thus, when a user takes a meal, air flows in from the air inlet hole 10a1, passes through the third air flow channel 10d, flows into the mouthpiece 10 from the notch groove 10c1, and flows out from the mouth end 10a2 to the mouth of the user together with the liquid mist atomized by the ultrasonic atomizing assembly 20.

As will be understood in conjunction with fig. 6, the ultrasonic atomizing assembly 20 includes an atomizing plate 21, an upper cover 22, an air flow member 23, a liquid guide member 24, a lower cover 25, a circuit board 26, a bottom cover 27, and a fixing base 28. The upper cap 22, lower cap 25, and bottom cap 27 define a housing for the ultrasonic atomization assembly 20.

As shown in fig. 7, the atomizing sheet 21 includes a base 211, an ultrasonic transducer 212, and a lead wire 213.

The substrate 211 comprises a metal sheet or a thin film sheet, and the ultrasonic transducer 212 comprises a ring-shaped piezoelectric ceramic. The base 211 has an atomization region 211a, and the atomization region 211a includes a plurality of micro-holes penetrating through the base 211. The cross section of the atomization region 211a is substantially circular, and the pore size and density of the micropores can be referred to the prior art. The lead 213 includes a positive electrode lead and a negative electrode lead, and one end of the lead 213 is electrically connected to the ultrasonic transducer 212 and the other end is coupled to the battery cell 30 c. Thus, under the action of the electric power provided by the battery cell 30c, the ultrasonic transducer 212 drives the substrate 211 to vibrate at a high speed, so as to atomize the liquid matrix in the micropores to form liquid mist, and the liquid mist is sprayed out of the micropores, passes through the central hole of the annular piezoelectric ceramic and then enters the first chamber a. The holder 28 holds the base 211 and the ultrasonic transducer 212. When the inner connecting portion 10c and the outer connecting portion 10b are received in the first chamber a of the ultrasonic atomizing assembly 20, the inner connecting portion 10c abuts against the fixed seat 28 to form a substantial seal, so that when a user inhales, air flows in from the air inlet hole 10a1, passes through the third air flow channel 10d, and flows only from the notch groove 10c1 into the mouthpiece 10. It will be appreciated that the end of the inner connecting portion 10c abutting the holder 28 forms the distal end of the nozzle 10.

As will be understood in conjunction with fig. 8, the upper cover 22 includes a first chamber a, a fourth chamber B, and a sixth chamber C. The first chamber a communicates with the fourth chamber B through the through-hole 22a, and the sixth chamber C is spaced from the other chambers. The lower cover 25 includes a fifth chamber D. The atomizing plate 21 is horizontally arranged in the first chamber a and is approximately parallel to the mouth end 10a2, the atomizing area 211a is coaxially arranged with the through hole 22a, a side of the atomizing area 211a facing away from the mouth end 10a2 forms a second surface, and a side facing the mouth end 10a2 forms a first surface. It will be appreciated that after the ultrasonic atomizing assembly is detached from the mouthpiece 10, the atomizing plate 21 is exposed or bare within the first chamber a; the part of the chamber a located above the nebulization area 211a forms a nebulization chamber. A step is formed in the first chamber a, and the outer connecting portion 10b abuts on the step when the outer connecting portion 10b is received in the first chamber a of the ultrasonic atomizing assembly 20. The upper cover 22 also has a boss 22C and a third airflow hole 22d, the third airflow hole 22d communicating with the sixth chamber C; a projection 22c is formed in the first chamber a above the step on which the third airflow hole 22d is formed.

The upper cover 22 is detachably connected to the lower cover 25, for example, by a snap connection. After the upper cover 22 and the lower cover 25 are connected, the atomizing plate 21, the upper cover 22 and the lower cover 25 jointly define at least a partial liquid storage cavity for storing an atomizing liquid matrix; in a preferred embodiment, the reservoir is defined by the atomizing plate 21, the holder 28, the upper cover 22 and the lower cover 25. The volume of the liquid storage cavity is less than or equal to the sum of the volume of the fourth cavity B and the volume of the fifth cavity D. The cover 22 also has a movable cover 22b, by which the reservoir is openable for filling the reservoir with the liquid substrate, through the movable cover 22 b.

The lower cover 25 further includes a holder 25a and a via 25 b. A holder 25a is provided in the fifth chamber D, and the liquid guide 24 has one end held in the holder 25a and the other end in contact with or abutting against the second surface of the atomization region 211 a. In the example of fig. 6, the holder 25a is formed by a plurality of baffles provided at intervals, the plurality of baffles being arranged along the circumferential direction of the liquid guide 24. The fluid-conducting member 24 is a material having the function of transporting and/or storing a liquid matrix, such as cotton, fiberglass cord, or the like. The length of the liquid guide 24 is 3mm to 15mm, preferably 3mm to 12mm, more preferably 3mm to 10mm, and still more preferably 3mm to 8 mm. The length of the fluid-conducting member 24 exceeding 15mm is not conducive to delivering the liquid substrate to the second surface of the atomization zone 211 a. It should be noted that, in the example of fig. 2, the liquid guide 24 is vertically placed (or arranged along the axial direction or the height direction of the ultrasonic atomization device 100), and the length of the liquid guide 24 is the length of the liquid guide in the vertical direction; in other examples, if the liquid guiding member 24 is disposed obliquely, the length of the liquid guiding member 24 may be the length of the liquid guiding member 24 itself, and preferably the projection length of the liquid guiding member in the axial direction of the ultrasonic atomization device 100.

As shown in fig. 9, the airflow member 23 includes a second airflow passage 23a extending substantially laterally, and a first airflow hole 23b communicating with the second airflow passage 23a and extending axially. One end of the airflow member 23 having the second airflow passage 23a is received in the sixth chamber C so that the third airflow hole 22d is in fluid communication with the second airflow passage 23 a; specifically, one end of the air flow member 23 having the second air flow passage 23a abuts the upper cover 22, so that the third air flow hole 22d is air-tightly in fluid communication with the second air flow passage 23 a. In a preferred embodiment, one end of the airflow member 23 has a protrusion, by which it abuts the upper cover 22; the protrusions are provided around the peripheral side edge of the second air flow passage 23a, and the height of the protrusions is not limited herein. The other end of the airflow member 23 passes through the through hole 25 b. It is readily envisioned that in other examples, it is also possible that the airflow member 23 is formed integrally with the upper cover 22 (or lower cover 25), or formed from a portion of the upper cover 22, or formed from a portion of the lower cover 25.

As will be understood from fig. 10, one surface of the wiring board 26 abuts against the lower cover 25, and has an electrical connection portion 26a and an electrical connection portion 26b, one end of the positive electrode lead is soldered to the electrical connection portion 26a, and one end of the negative electrode lead is soldered to the electrical connection portion 26 b. The other surface of the wiring board 26 abuts against the bottom cover 27, and has an electrical contact portion 26c electrically connected to the electrical connection portion 26a and an electrical contact portion 26d electrically connected to the electrical connection portion 26 b. When the ultrasonic atomization assembly 20 is connected to the power supply assembly 30, the two electrodes 30a of the power supply assembly 30 are electrically connected to the electrical contacts 26c and 26d in a one-to-one correspondence.

The bottom cover 27 is sleeved on a part of the lower cover 25, the bottom cover 27 is provided with two electrode through holes 27a, and the electrodes 30a can be contacted with the electric contact parts through the electrode through holes 27a to form electric connection. The bottom cover 27 further has a fourth air hole 27b, and after the other end of the air flow member 23 passes through the through hole 25b, the first air hole 23b may be exposed outside the fourth air hole 27b, or the first air hole 23b is in fluid communication with the through hole 25 b. Thus, the first sensing channel penetrates from the lower surface of the bottom cover 27 to the inner surface of the first chamber a.

As will be understood with reference to fig. 2-3, the ultrasonic atomization assembly 20 is removably coupled to the power supply assembly 30. In the example of fig. 2-3, the power module 30 has a magnetic element 30b and the bottom cover 27 is made of stainless steel; the magnetic element 30b and the bottom cover 27 may magnetically couple the ultrasonic atomization assembly 20 and the power supply assembly 30.

The power module 30 includes a second chamber E and a third chamber (not shown) that are separated, and a battery cell 30c, a circuit board 30d, and a sensor 30E are disposed in the third chamber.

The battery cell 30c is used for providing power; the battery cell 30c may be a rechargeable battery cell. The circuit board 30d is used for overall control of the ultrasonic atomizing device 100. The sensor 30e is used for sensing the sucking of the user to feed back a sucking signal to the circuit board 30d, so as to control the ultrasonic atomization assembly 20 to start atomization. The sensor 30e may be an airflow sensor or an air pressure sensor. The battery cell 30c and the circuit board 30d are disposed back and forth in the thickness direction of the power supply module 30, and the sensor 30e is electrically connected to the circuit board 30d and fixedly fitted in the sensor mounting chamber. The sensor mounting chamber is disposed in the third chamber.

Referring to fig. 2 again, the two electrodes 30a and the magnetic element 30b are exposed in the second chamber E. Further, a first air flow path 30f is also provided in the second chamber E. The second airflow hole 30g fluidly communicates the first airflow passage 30f with the sensor mounting chamber; in the example of fig. 2, one end of the second airflow hole 30g is disposed on the bottom wall of the second chamber E and is disposed offset from one end of the first airflow hole 23b (i.e., the corresponding fluid communication ports are offset, or both are offset), and the other end is disposed in the third chamber; one end of the second airflow hole 30g is in fluid communication with one end of the first airflow hole 23b through the first airflow passage 30 f. In other examples, one end of the second airflow hole 30g and one end of the first airflow hole 23b may be coaxially disposed.

After the ultrasonic atomization assembly 20 is connected to the power supply assembly 30, a part of the ultrasonic atomization assembly 20 is accommodated in the second chamber E, and the first airflow passage 30f abuts against the bottom cover 27, so that the first airflow hole 23b, the first airflow passage 30f, and the second airflow hole 30g are in airtight fluid communication with each other. In a preferred embodiment, the first air flow channel 30f includes a projection provided around the peripheral side edge of the first air flow channel 30f, by which the bottom cover 27 is elastically abutted; the height of the protrusions is not limited herein.

Thus, the second air flow hole 30g, the first air flow channel 30f, the first air flow hole 23b (or, the fourth air flow hole 27b and the first air flow hole 23b), the second air flow channel 23a, and the third air flow hole 22d form a sensing channel; wherein the second airflow hole 30g forms a second sensing channel; the first air flow hole 23b, the second air flow channel 23a, and the third air flow hole 22d form a first sensing channel. The sensing channel is in fluid communication with the third airflow channel 10d through the cutaway slot 10b 3; when the user sucks, the sensor 30e can sense the sucking airflow through the sensing channel, and then feeds back a sucking signal to the circuit board 30 d. In a preferred embodiment, the sensor 30e is an air pressure sensor, when a user inhales, a negative pressure is formed in the sensing channel, and the sensor 30e senses the negative pressure and feeds back a signal to the circuit board 30d to determine whether the user inhales.

As will be appreciated in conjunction with fig. 11, the circular atomization zone 211a has a diameter d 1; the opening is shaped as an elliptical mouth end 10a2 with a minor axis distance d 2. The atomizing area 211a is disposed coaxially with the mouth end 10a 2; in this way, the liquid mist atomized by the atomizing area 211a can flow directly from the mouth end 10a2 into the mouth of the user. Further, to prevent condensate from adhering to the inner walls of the mouthpiece 10, the short axial distance d2 of the mouth end 10a2 should be greater than or equal to the diameter d1 of the atomizing area 211 a; preferably, d2 is more than or equal to d1+0.5 mm. It is further determined that the open area of the mouth end 10a2 is greater than or equal to the area of the atomization zone 211 a; the area of the projection of the elliptical mouth end 10a2 on the atomizing plate 21 and the fixed seat 28 is greater than or equal to the area of the atomizing area 211 a.

It will be appreciated that for other shapes of the atomizing area 211a and the mouth end 10a2, the opening area of the mouth end 10a2 should be greater than or equal to the area of the atomizing area 211a in order to prevent condensate from adhering to the inner walls of the mouthpiece 10; alternatively, the area of the projection of the mouth end 10a2 on the atomizing plate 21 should be greater than or equal to the area of the atomizing area 211 a; alternatively, the area of the projection of the mouth end 10a2 on the atomizing plate 21 and the fixing base 28 should be greater than or equal to the area of the atomizing area 211 a.
