Description

Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a liquid spraying device and an electronic cigarette. Background Art

[0002] Traditional cigarettes are harmful to the human body, and electronic cigarettes have emerged as a substitute. The Chinese patent document with publication number CN203424292U discloses an atomization device, including a heating wire assembly consisting of a heating wire, a first oil guide rope and an electronic wire, and a vent pipe, wherein the vent pipe has an assembly hole for accommodating the heating wire assembly, and also includes a second oil guide rope arranged side by side with the first oil guide rope in the assembly hole and in contact with the heating wire.

[0003] A Chinese patent document with publication number CN203913377U discloses an integrated disposable electronic cigarette, including an integrated hollow cigarette shell, a central side wall of which is provided with a radial first air inlet through hole, the first air inlet through hole is a battery accommodating cavity in the direction of the cigarette butt, and is an atomizer accommodating cavity in the direction of the cigarette mouthpiece; the shell is provided with a luminous body, a battery, a hollow fixing seat and an atomizer device in sequence from the cigarette butt to the cigarette mouthpiece, and the atomizer device includes a smoke oil cotton, a U-shaped oil guide rope, a heating wire, a fiber tube and a hollow rubber cover.

[0004] A Chinese patent document with publication number CN204232305U discloses an electronic cigarette, which includes an atomizer and a battery assembly. The atomizer includes an oil storage assembly, a suction nozzle arranged at one end of the oil storage assembly, an air guide tube axially sleeved in the oil storage assembly, and an atomizer assembly detachably inserted in the end of the oil storage assembly away from the suction nozzle. The atomizer assembly includes an atomizer seat inserted into the oil storage assembly, a glass fiber tube inserted in one end of the atomizer seat, an atomizer electrode assembly inserted at the other end of the atomizer seat and used for being electrically connected to the battery assembly, and at least one group of heating wire assemblies inserted in the glass fiber tube. The heating wire assembly includes an oil guide rope and a heating wire wound on the oil guide rope and electrically connected to the atomizer electrode assembly. One end of the oil guide rope adjacent to the suction nozzle is a fixed end, and the other end is a free end. The fixed end passes through the glass fiber tube and is clamped at the end or side wall of the atomizer seat for absorbing tobacco oil from the oil storage cavity. The free end is accommodated in the glass fiber tube and extends along the axial direction of the glass fiber tube.

[0005] It can be found that the current method of atomizing e-liquid on the market is basically to use a heating wire to directly heat the oil guide rope soaked with e-liquid. However, as the heat generation increases, the oil guide rope's oil guide rate does not keep up, and the temperature of the heating wire assembly will rise. When the temperature reaches a certain level, the oil guide rope will deteriorate at high temperature, and the e-liquid will burn at high temperature, giving off a burnt smell. There may be a risk of carbonization of the oil guide rope in the later stage of smoking, which will affect the oil supply of the oil guide rope and the smoking experience. Summary of the invention

[0039] The following specific embodiments illustrate the implementation of the present invention, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Although the description of the present invention will be introduced in conjunction with the preferred embodiment, this does not mean that the features of this invention are limited to this implementation. On the contrary, the purpose of introducing the invention in conjunction with the implementation is to cover other options or modifications that may be extended based on the claims of the present invention. In order to provide a deep understanding of the present invention, the following description will include many specific details. The present invention can also be implemented without using these details. In addition, in order to avoid confusion or blurring the focus of the present invention, some specific details will be omitted in the description.

[0040] In the prior art, the method of atomizing the e-cigarette oil is basically to directly heat the glass fiber oil guide rope with a heating wire, which may cause the risk of carbonization of the oil guide rope in the later stage of inhalation, thereby affecting the oil supply of the oil guide rope and the inhalation experience. The present invention provides a liquid spraying device, which sprays liquid to an atomizing unit through the liquid spraying device, and the atomizing unit heats the fluid to atomize the fluid. During the inhalation process, the atomizing unit does not contact the liquid spraying device, there is no risk of carbonization, and the inhalation experience is good.

[0041] refer to Figure 1 The present invention provides a liquid spray device 10, which can be used in electronic cigarettes, but is not limited to being used in electronic cigarettes. The liquid spray device 10 includes: a first shell 11, the first shell 11 has a first inner cavity 12, and a liquid inlet 13 and a liquid spray port 14 connected to the first inner cavity 12 are respectively provided on different shell walls of the first shell 11, and liquid, such as e-cigarette oil, is provided to the liquid spray device 10 through the liquid inlet 13. In this embodiment, the liquid inlet 13 is provided on the top wall of the first shell 11, and the liquid spray port 14 is provided on the bottom wall of the first shell 11. The side wall of the first shell 11 is located between the top wall and the bottom wall, and together surrounds the first inner cavity 12.

[0042] In other embodiments, the liquid inlet may not be provided on the first shell of the liquid spraying device, and the liquid spraying device carries its own liquid, and there is no need to provide liquid to the liquid spraying device through the liquid inlet.

[0043] Continue to refer Figure 1 The liquid spray port 14 includes a plurality of micropores 16, and the aperture of the micropores 16 satisfies that the fluid will not actively flow out of the micropores 16 after flowing into the micropores 16, wherein the fluid in the micropores 16 will not actively flow out of the micropores 16 under the action of surface tension and without pressure. The aperture of the micropores 16 is 0.005 mm to 0.1 mm, including 0.005 mm and 0.1 mm. The aperture of each micropore 16 may meet the above requirements, or the aperture of some micropores 16 may meet the above requirements. "Not under pressure" can be understood as: the fluid in the micropore 16 is not subject to external pressure except its own gravity.

[0044] Continue to refer Figure 1 Combined with Figure 2 As shown, a vibration part 20 is further provided in the first inner cavity 12 of the first housing 11, and the vibration part 20 is covered above the liquid spraying port 14, and is used to reciprocate and vibrate after power is turned on to make the fluid spray out from the micropores 16. In this embodiment, the vibration part 20 has a second inner cavity connected to the first inner cavity 12, and a vibration unit is provided in the second inner cavity. The fluid in the first inner cavity 12 can flow into the liquid spraying port 14 from the second inner cavity of the vibration part 20, and the vibration part 20 is covered on the liquid spraying port 14, which is equivalent to the liquid spraying port 14 being in the second inner cavity.

[0045] After the liquid spraying device 10 is applied to the electronic cigarette, the liquid storage part of the electronic cigarette is connected to the liquid inlet 13 of the liquid spraying device 10, and liquid is supplied to the liquid spraying device 10. After the fluid flows into the first inner cavity 12, it flows into the second inner cavity, and finally flows into the micropores 16 in the liquid spraying port 14. When the vibration unit is not powered on, the vibration unit does not vibrate, and the fluid in the micropores 16 will not actively flow out of the micropores 16, that is, the liquid spraying device 10 will not spray liquid.

[0046] When the vibration unit is powered on, the vibration unit vibrates back and forth, and the fluid in the micropores 16 is pressurized and sprayed from the micropores 16 to the atomization unit. Under the action of the atomization unit, the fluid is atomized to produce aerosol. When the liquid spraying device 10 of the present invention is used to spray liquid, the atomization unit and the liquid spraying device 10 are not in contact, and there is no risk of the atomization unit heating the fluid while heating the liquid spraying device 10, and there is no risk of carbonization, which provides consumers with a better smoking experience.

[0047] Furthermore, since the micropores 16 in the liquid spray port 14 of the liquid spray device 10 of the present invention will spray liquid only when the vibration unit is energized; the present invention can achieve quantitative liquid spraying of the liquid spray port 14 by setting a corresponding number of micropores 16 or changing the vibration frequency of the vibration unit or changing the number of vibration units participating in the vibration. Consumers can control the liquid spraying amount of the liquid spray device 10 according to their own suction habits, and consumers have a better suction experience.

[0048] Continue to refer Figure 2 Combined with Figure 3 As shown, the vibration part 20 of the present invention comprises: a second shell 20a, the second shell 20a is covered on the liquid injection port 14, and the shell wall of the second shell 20a forms a second inner cavity. The vibration unit of the vibration part 20 comprises: a diaphragm 21 and a vibration source 22, the diaphragm 21 divides the second inner cavity into a first sub-cavity 23 and a second sub-cavity 24 that are not connected, the first sub-cavity 23 is connected to the first inner cavity 12, the liquid injection port 14 is located in the first sub-cavity 23 and is connected to the first sub-cavity 23, and the second shell 20a is provided with at least one liquid inlet channel 201 for fluid to flow from the first inner cavity 12 into the first sub-cavity 23.

[0049] The vibration source 22 is located in the second sub-cavity 24 and is arranged on the diaphragm 21, and is used to drive the diaphragm 21 to vibrate back and forth after power is supplied so that the fluid is ejected from each micropore 16. In this embodiment, the vibration source 22 includes: multiple rows of piezoelectric units, and the number of piezoelectric units in each row is equal, so that the fluid in the micropore 16 can be uniformly pressurized. The piezoelectric unit includes a piezoelectric ceramic sheet, which generates an inverse piezoelectric effect after power is supplied, and the electrical energy is converted into mechanical energy, and the piezoelectric ceramic sheet can vibrate periodically. In other embodiments, the vibration source can be of other types as long as it can vibrate back and forth after power is supplied.

[0050] The material of the diaphragm 21 is polyimide, polydimethylsiloxane or silicon film. The diaphragm 21 vibrates with the vibration of the vibration source 22 to drive the fluid in the micropore 16 to eject from the micropore 16, and on the other hand, blocks the fluid in the first sub-cavity 23 from leaking into the second sub-cavity 24, causing the vibration source 22 to short-circuit.

[0051] In this embodiment, the diaphragm 21 is parallel to the shell wall where the liquid ejection port 14 is located, and is close to the liquid ejection port 14, so that when the vibration source 22 is powered on, it reciprocates in the direction toward the liquid ejection port 14, and the diaphragm 21 can reciprocate in the direction toward the liquid ejection port 14 to make the fluid in the micropore 16 pressurized and ejected from the micropore 16. In other embodiments, at least a portion of the diaphragm is parallel to or perpendicular to the shell wall where the liquid ejection port 14 is located.

[0052] It should be noted that “parallel” can be strictly parallel or roughly parallel, with a certain angle of deviation allowed. “Vertical” can be strictly vertical or roughly vertical, with a certain angle of deviation allowed.

[0053] In order to better fix the vibration part 20 at the liquid injection port 14, refer to Figure 1 and Figure 2 Combined with Figure 4 As shown, a fixing portion 30 for fixing the vibration portion 20 is also provided in the first inner cavity 12, along the direction from the top wall to the bottom wall of the first shell 11 ( Figure 1 The fixing portion 30 is provided with a first portion 30a and a second portion 30b in sequence, the first portion 30a abuts against the top wall, and the second portion 30b abuts against the second shell 20a to fix the second shell 20a to the bottom wall. The first portion 30a of the fixing portion 30 has a third inner cavity 31, and the second portion 30b has at least one liquid outlet channel 32, and the first inner cavity 12 can be connected to the first sub-cavity 23 through the liquid outlet channel 32. Figure 1 Two liquid outlet channels 32 are shown in FIG. 1 , and other numbers of liquid outlet channels may be provided in other embodiments.

[0054] In this embodiment, the third inner cavity 31 of the first portion 30a is connected to the first inner cavity 12 and the liquid outlet channel 32 respectively. Figure 3The second housing 20a is provided with at least one liquid inlet channel 201 for the fluid to flow from the liquid outlet channel 32 into the first sub-chamber 23; Figure 2 The dashed arrows in the middle represent the flow direction of the fluid.

[0055] Continue to refer Figure 4 , the second part 30b is provided with a recess 33 for accommodating one end of the second shell 20a, and the recess 33 is staggered with the liquid outlet channel 32. In this embodiment, the recess 33 is located between the two liquid outlet channels 32. The size of the recess 33 matches one end of the second shell 20a, which can limit the movement of the second shell 20a relative to the liquid spray port 14, so that the liquid spray port 14 can stably and quantitatively spray liquid to the atomization unit. Otherwise, when the second shell 20a and the liquid spray port 14 are misaligned, the liquid spray port 14 is partially located outside the first sub-cavity 23 of the second shell 20a, or the liquid spray port 14 is completely located outside the second sub-cavity 24 of the second shell 20a, and the fluid in the micropores 16 in the liquid spray port 14 will not be sprayed out from the micropores 16, affecting the use of the liquid spray device 10.

[0056] Continue to refer Figure 1 In this embodiment, the outer peripheral surface of at least one of the first part 30a and the second part 30b of the fixing part 30 abuts against the side wall of the first shell 11. After such arrangement, on the one hand, the fixing part 30 abuts against the side wall and the top wall of the first shell 11, and can abut against the vibration part 20 more tightly to better fix the vibration part 20 to the bottom wall of the first shell 11; on the other hand, the fluid flowing into the first inner cavity 12 from the liquid inlet 13 of the first shell 11 can completely flow into the third inner cavity 31 of the fixing part 30, and will not penetrate into the tiny gap between the fixing part 30 and the top wall and the side wall of the first shell 11, and will remain in the tiny gap between the fixing part 30 and the top wall and the side wall of the first shell 11, so that the utilization rate of the fluid is high.

[0057] In addition, refer to Figure 1 The first housing 11 of the embodiment of the present invention is provided with a protrusion 15. In this embodiment, the protrusion 15 is provided on the top wall of the first housing 11, and the liquid inlet 13 is provided on the protrusion 15. In other embodiments, the protrusion may be provided on the side wall of the first housing. The protrusion 15 of the liquid spraying device 10 is used to be inserted into the liquid storage part of the electronic cigarette to introduce the fluid in the liquid storage part into the first inner cavity 12 of the first liquid spraying device 10.

[0058] It should be noted that the shape of the first shell 11 of the liquid spraying device 10 is not limited, and it can be installed in the inner cavity of the electronic cigarette. The material of the first shell 11 is not limited. In this embodiment, the first shell 11 is one of polypropylene, COC resin, photosensitive polymer, and elastic polymer material.

[0059] refer to Figure 5 Combined with Figure 1As shown, the present invention also provides an electronic cigarette 4, using any of the above-mentioned liquid spraying devices 10. The electronic cigarette 4 includes: a cigarette shell 40, the cigarette shell 40 has an inner cavity 41; a liquid storage part 43 is provided in the inner cavity 41 of the cigarette shell 40, and a fluid is stored in the liquid storage part 43. The fluid can be a smoke oil, and smoke oil can generate smoke after atomization. The liquid storage part 43 has a liquid outlet, and the liquid outlet of the liquid storage part 43 is connected to the liquid inlet 13 of the liquid spraying device 10; combined Figure 1 As shown, the protrusion 15 of the liquid spraying device 10 is inserted into the liquid inlet 13 of the liquid storage part 43, and the outer peripheral surface of the protrusion 15 is provided with a sealing member 4a to be interference fit with the inner peripheral surface of the liquid inlet 13 to prevent the protrusion 15 and the liquid inlet 13 from being connected unstably and the fluid in the liquid storage part 43 from leaking into the inner cavity 41 of the cigarette shell 40. In this embodiment, the sealing member 4a is a silicone plug, and can also be other types of sealing members as long as they can achieve sealing.

[0060] It should be noted that the specific location of the liquid storage part of the electronic cigarette is not limited, as long as the liquid storage part can provide liquid for the electronic cigarette to the liquid spraying device, and the liquid spraying device can spray liquid to the atomizing unit. For example, in other embodiments, the liquid storage part is arranged outside the cigarette shell of the electronic cigarette.

[0061] Continue to refer Figure 5 Combined with Figure 1 and Figure 2 As shown, an atomizing unit 46 is further provided in the inner cavity 41 of the electronic cigarette 4. The atomizing unit 46 is arranged facing the liquid spraying port 14 of the liquid spraying device 10 and is used to atomize the fluid sprayed from the liquid spraying port 14. Figure 6 The atomizing unit 46 has a shell 462, and the shell 462 has an opening 46a facing the liquid spray port 14. The heating part 48 in the atomizing unit 46 is arranged on the bottom wall of the shell 462, and the heating part 48 is a heating sheet or a heating circuit or other heating body.

[0062] In this embodiment, the liquid spraying port 14 of the liquid spraying device 10 is completely covered by the opening 46a of the atomizing unit 46, and the fluid sprayed from the liquid spraying port 14 completely falls into the atomizing unit 46, which can prevent the fluid from splashing elsewhere during the liquid spraying process of the liquid spraying port 14. In other embodiments, the opening 46a of the atomizing unit 46 can partially cover the liquid spraying port 14. In addition, at least one through hole 461 is provided on the side wall of the housing 462 of the atomizing unit 46, and four through holes 461 are shown in the figure. In this embodiment, each through hole 461 extends from the liquid spraying port 14 to the atomizing unit 46. The heating part 48 in the atomizing unit 46 atomizes the fluid, and the generated aerosol can flow out from the through hole 461 for suction.

[0063] Continue to refer Figure 5 , along the depth direction of the cigarette shell 40 ( Figure 5(shown in the H direction in the figure), a mouthpiece 42 is provided at one end of the cigarette shell 40, and an air inlet 49 is provided at the other end. The aerosol generated by fluid atomization can flow out of the mouthpiece 42 along with the outside air entering through the air inlet 49 for inhalation. Along the direction from the air inlet 49 to the mouthpiece 42, the inner cavity 41 of the cigarette shell 40 is provided with: a power supply unit (not shown in the figure), used to supply power to the atomization unit 46 and the liquid spraying device 10 for the electronic cigarette 4; a first bracket 44, fixed on the shell wall of the cigarette shell 40; an atomization unit 46, provided on the first bracket 44; a liquid spraying device 10; a liquid storage unit 43; a second bracket 45, one end of which is connected to the liquid storage unit 43, and the other end is connected to the mouthpiece 42.

[0064] The atomization unit 46 is movably connected to the first bracket 44. In this embodiment, the atomization unit 46 is located in the first bracket 44 and is movably connected to the first bracket 44 through a screw 47. The distance between the atomization unit 46 and the liquid spraying device 10 can be adjusted by screwing the screw 47, so that the risk of the atomization unit 46 and the liquid spraying device 10 interfering with each other and failing to be installed in the inner cavity 41 of the electronic cigarette 4 due to processing size errors can be reduced.

[0065] The working principle of electronic cigarette 4 is as follows:

[0066] refer to Figure 5 Combined with Figure 1 and Figure 2 As shown, the dotted arrows in the cigarette shell 40 represent the flow direction of the fluid, and the solid arrows represent the flow direction of the aerosol generated by the atomization of the fluid and the external air. Specifically, after the protrusion 15 of the liquid spraying device 10 is inserted into the liquid storage portion 43, the fluid in the liquid storage portion 43 flows into the liquid spraying device 10 under the action of gravity, and then flows into the micropores 16 of the liquid spraying port 14. When the power supply unit does not supply power to the liquid spraying device 10, the vibration unit does not vibrate, the fluid in the micropores 16 will not actively flow out of the micropores 16, and the liquid spraying device 10 will not spray liquid.

[0067] When the power supply unit supplies power to the liquid spraying device 10, the vibration unit is powered on, the vibration unit vibrates back and forth, and the fluid in the micropores 16 is pressurized and sprayed from the micropores 16 to the atomizing unit 46. When the atomizing unit 46 is powered on, the heating unit 48 generates heat, and after the fluid contacts the heating unit 48, the fluid is atomized to generate aerosol. When the consumer inhales, the aerosol is mixed with the outside air inhaled from the outside and enters the oral cavity through the mouthpiece 42.

[0068] It should be noted that, in order to realize the quantitative liquid spraying of the liquid spraying device 10, the electronic cigarette includes a control unit (not shown in the figure), and the control unit can control the number of vibration units of the vibration part that are powered on; or the control unit can control the vibration frequency of the vibration unit of the vibration part; or the control unit can control the number of vibration units of the vibration part that are powered on and control the vibration frequency of the vibration unit of the vibration part. Thus, the quantitative liquid spraying of the liquid spraying device 10 is realized by operating the control unit.

[0069] In summary, the above embodiments provided by the present invention are only illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
