TECHNICAL FIELD

[0044] The following will be described in combination with Figure 1 - Figure 7 The atomizing device described in the embodiments of the present application is described as follows, as shown in Figure 1 and Figure 2 The atomizing device can include an atomizing assembly 5, a liquid guide pipe 4, a liquid storage shell 1, a support 2 and a liquid storage bottle 3; one side of the support 2 is connected with the liquid storage shell 1, and together with the liquid storage shell 1 forms a first liquid storage cavity 11; the other side of the support 2 is connected with the liquid storage bottle 3, and the liquid storage bottle 3 has a second liquid storage cavity 31 for storing an atomizing substrate; the atomizing assembly 5 is arranged in the first liquid storage cavity 11; the liquid guide pipe 4 is arranged in the support 2, and the liquid guide pipe 4 includes opposite first and second ends 43 and 44, the first end 43 is located in the first liquid storage cavity 11, the first end 43 is provided with a gas guide hole 41 and a liquid guide hole 42, the gas guide hole 41 is communicated with the outside through the first liquid storage cavity 11, the liquid guide hole 42 is communicated with the atomizing assembly 5, the second end 44 is located in the second liquid storage cavity 31 and communicated with the second liquid storage cavity 31, and the opening size of the liquid guide hole 42 is larger than that of the gas guide hole 41.

[0045] In this embodiment, the second end 44 of the liquid guide tube 4 is connected to the second liquid storage chamber 31, and the first end 43 is connected to the atomizing component 5 through the liquid guide hole 42. In this way, the atomizing matrix can flow out from the second liquid storage chamber 31, be transmitted through the liquid guide tube 4, and be transmitted to the atomizing matrix in the first liquid storage chamber 11 through the liquid guide hole 42, thereby realizing the atomizing component 5 to atomize the atomizing matrix to obtain an aerosol. Since the air guide hole 41 is connected to the outside through the first liquid storage chamber 11, while the atomizing matrix flows from the second liquid storage chamber 31 to the atomizing component 5, outside air can pass through the air guide hole 41 from the first liquid storage chamber 11 and then be transmitted to the second liquid storage chamber 31 by the liquid guide tube 4. The air exchange path and the liquid inlet path are set independently, which means that gas can be replenished in the second liquid storage chamber 31 in time while the atomizing matrix flows out of the second liquid storage chamber 31 to balance the pressure in the second liquid storage chamber 31. This can improve the reliability and stability of providing the atomizing matrix to the atomizing component 5, and make it easier to reasonably arrange the size of the liquid guide hole 42, avoiding it being too large or too small. This can meet a certain number of suction ports and also avoid wicking.

[0046] In addition, since the opening size of the liquid guide hole 42 is larger than the opening size of the air guide hole 41, the opening size of the air guide hole 41 is smaller. This makes it easier to form an oil film in the air guide hole 41 when the air pressure in the first liquid storage chamber 11 is balanced.

[0047] In this embodiment, the atomizing component 5 is used to atomize the atomizing matrix to form an aerosol for easy inhalation by the user. The liquid guide tube 4 can serve as a flow guide, and its interior can be hollow to facilitate the flow of the atomizing matrix. The liquid guide tube 4 includes a first end 43 and a second end 44. The liquid guide hole 42 and the air guide hole 41 can be opened on the circumferential side of the first end 43 of the liquid guide tube 4. The end of the first end 43 can be sealed, or the end of the first end 43 can be sealed by other components, etc. The end of the second end 44 can be open and can communicate with the second liquid storage chamber 31.

[0048] In some embodiments, the liquid guiding hole 42 and the air guiding hole 41 are arranged alternately. The liquid guiding hole 42 can be a circular hole or a square hole, etc., and the number of liquid guiding holes 42 can be one or at least two, etc. The air guiding hole 41 can be a circular hole or a square hole, etc., and the number of air guiding holes 41 can be multiple. In this embodiment, no specific limitation is made on this.

[0049] In some embodiments, a plurality of liquid guiding holes 42 may be spaced apart along the circumferential and / or axial direction of the liquid guiding tube 4, or the plurality of liquid guiding holes 42 may be provided on opposite sides of the liquid guiding tube 4.

[0050] In some embodiments, multiple air guide holes 41 may be arranged at intervals along the circumference of the liquid guide tube 4, or multiple air guide holes 41 may be arranged on opposite sides of the liquid guide tube 4.

[0051] In some embodiments, the support 2 serves to support and connect, one side of the support 2 is connected with the liquid storage shell 1, and the other side is connected with the liquid storage bottle 3. One side of the support 2 is enclosed with the liquid storage shell 1 to form a first liquid storage cavity 11, and the liquid storage bottle 3 has a second liquid storage cavity 31, which can be used to store the atomization substrate.

[0052] In the embodiments of the present application, the atomization assembly 5 can be arranged in the first liquid storage cavity 11, so that the liquid guide hole 42 formed in the first end 43 of the liquid guide tube 4 is in communication with the atomization assembly 5. Since the first end 43 of the liquid guide tube 4 is located in the first liquid storage cavity 11, the liquid guide hole 42 formed in the first end 43 can be in communication with the atomization assembly 5, and the second end 44 is located in the second liquid storage cavity 31 and is in communication with the second liquid storage cavity 31. In this way, under the flow guiding effect of the liquid guide tube 4, the atomization substrate in the second liquid storage cavity 31 can be guided to the atomization assembly 5 in the first liquid storage cavity 11, so as to realize liquid supply to the atomization assembly 5.

[0053] In some embodiments, the first end 43 of the liquid guide tube 4 is provided with an air guide hole 41, and the air guide hole 41 can be in communication with the outside through the first liquid storage cavity 11. In this way, after the air outside enters the first liquid storage cavity 11, it can enter the liquid guide tube 4 through the air guide hole 41 and then enter the second liquid storage cavity 31, so as to realize air supplement in the second liquid storage cavity 31 and balance the air pressure in the second liquid storage cavity 31.

[0054] In some embodiments, as shown in Figure 1 The atomization device has length direction, width direction and thickness direction perpendicular to each other, the length direction is parallel to the Y direction, and the width direction is parallel to the X direction.

[0055] When the user uses the atomization device, as shown in Figure 1 and Figure 2 The atomization device assumes a vertical posture, that is, the first liquid storage cavity 11 is located above the second liquid storage cavity 31. After the user smokes a certain number of puffs, the atomization device can be placed horizontally, so that the first liquid storage cavity 11 and the second liquid storage cavity 31 can be located at the same horizontal height. In this way, the atomization substrate can flow out of the second liquid storage cavity 31 and then be guided by the liquid guide tube 4 to flow to the atomization assembly 5 from the liquid guide hole 42, thereby realizing liquid supply to the atomization assembly 5. At the same time that the atomization substrate flows from the second liquid storage cavity 31 to the atomization substrate, a negative pressure is generated in the second liquid storage cavity 31, so that the air outside can enter the first liquid storage cavity 11 and then flow to the liquid guide tube 4 from the air guide hole 41 and then enter the second liquid storage cavity 31. After the air enters the second liquid storage cavity 31, it can balance the air pressure in the second liquid storage cavity 31. In this way, the reliability of air entering the second liquid storage cavity 31 can be adjusted, and the smoothness of the atomization substrate flowing out of the second liquid storage cavity 31 can be improved.

[0056] In some embodiments, the liquid guide hole 42 is arranged between the air guide hole 41 and the second end 44, so that the liquid guide hole 42 and the air guide hole 41 are arranged in a spaced manner. The position of the liquid guide tube 4 for guiding air and liquid is different, which can avoid mutual restriction of air guiding and liquid guiding, facilitate to ensure the effect of air guiding and liquid guiding, and thus the liquid guide hole 42 does not need to be designed to be too large or too small, but can be designed according to the requirement, which can meet the requirement of the number of suction ports and avoid the phenomenon of core paste of the atomization assembly 5. The size of the liquid guide hole 42 can be designed according to the requirement, so that the liquid supplied at one time can meet the suction of tens to one hundred ports.

[0057] As shown in Figure 1 and Figure 2 , the atomization device can further include a shell 8, and the liquid storage shell 1, the support 2 and the liquid storage bottle 3 can be arranged in the shell 8, so that the shell 8 can provide protection for the liquid storage shell 1, the support 2 and the liquid storage bottle 3. Among them, the support 2 can be connected with the inner wall of the shell 8.

[0058] In some embodiments of the present application, the atomization assembly 5 includes an atomization core 52 and a liquid guide element 51 with air permeability, as shown in Figure 3 , the liquid guide element 51 is provided with first and second installation holes 511 and 512 arranged side by side and spaced apart; the atomization core 52 is arranged in the first installation hole 511; the first end 43 is arranged in the second installation hole 512, and the atomization base flowing out of the liquid guide hole 42 is transmitted to the atomization core 52 through the liquid guide element 51.

[0059] In the embodiments of the present application, the atomization core 52 is arranged in the first installation hole 511, and the first end 43 is arranged in the second installation hole 512, so that the liquid guide element 51 can be sleeved outside the atomization core 52 and the first end 43 respectively, which can improve the convenience and reliability of the liquid guide element 51 in transmitting the atomization base flowing out of the liquid guide hole 42 to the atomization core 52. Since the liquid guide element 51 has air permeability, the liquid guide element 51 can transmit the air in the first liquid storage cavity 11 to the liquid guide tube 4 through the air guide hole 41, thereby realizing air supply to the second liquid storage cavity 31.

[0060] In some embodiments, the atomization core 52 can heat and atomize the atomization base to form an aerosol. The liquid guide element 51 can be oil storage cotton or high polymer cotton, etc., which is convenient for transmitting the atomization base. Moreover, the liquid guide element 51 has air permeability, for example, the liquid guide element 51 can be oil storage cotton or oil guide cotton, etc., so that the liquid guide element 51 can have pores for air to pass through. In this way, after the air outside enters the first liquid storage cavity 11, it can pass through the pores on the liquid guide element 51 from the air guide hole 41 into the liquid guide tube 4, and then diffuse into the second liquid storage cavity 31.

[0061] In some embodiments, when the atomization device is vertically placed, the first end 43 of the liquid guide tube 4 is located above the second end 44, and under the action of gravity, the top of the liquid guide element 51 absorbs less atomization substrate, and the ventilation effect is better. Therefore, the air guide hole 41 is arranged on the side of the liquid guide hole 42 away from the second end 44, so that the air guide hole 41 is arranged close to the top of the liquid guide tube 4, so as to realize that the liquid guide element 51 can guide the air outside into the air guide hole 41.

[0062] In some embodiments, the first mounting hole 511 and the second mounting hole 512 are arranged side by side and spaced apart, so that the first end 43 is arranged side by side with the atomization core 52.

[0063] In some embodiments, the liquid guide hole 42 is arranged on the side of the liquid guide tube 4 facing the atomization core 52, which is beneficial to shorten the transmission path of the atomization substrate, so that the atomization substrate flowing out of the liquid guide hole 42 can flow to the atomization core 52 better, and the reliability of supplying liquid to the atomization core 52 is improved.

[0064] As shown in the example, Figure 2 As shown in the example, the atomization core 52 is located on the right side of the liquid guide tube 4, and the liquid guide hole 42 can be arranged on the right side of the liquid guide tube 4 and close to the right side, so as to reduce the transmission path of the atomization substrate.

[0065] In some embodiments of the present application, the liquid guide tube 4 includes opposite first and second portions 45 and 46, and the first and second portions 45 and 46 are both provided with air guide holes 41; the atomization device includes a first flat state and a second flat state, in the first flat state, the first portion 45 is located above the second portion 46, and the first portion 45 and the atomization substrate form a first air passage that communicates with the air guide hole 41 on the first portion 45; in the second flat state, the second portion 46 is located above the first portion 45, and the second portion 46 and the atomization substrate form a second air passage that communicates with the air guide hole 41 on the second portion 46.

[0066] In the embodiments of the present application, when the atomization device is in the first flat state, the atomization substrate in the second liquid storage cavity 31 can flow to the first liquid storage cavity 11 along the second portion 46 of the liquid guide tube 4, the air guide hole 41 on the second portion 46 is blocked by the atomization substrate, and the air outside can enter the air guide tube along the air guide hole 41 on the first portion 45 and then flow to the second liquid storage cavity 31 through the first air passage, thereby ensuring the reliability of supplying air to the second liquid storage cavity 31 when the atomization substrate flows out of the second liquid storage cavity 31.

[0067] When the atomization device is in the second flat state, the atomization substrate in the second liquid storage cavity 31 can flow to the first liquid storage cavity 11 along the first part 45 of the liquid guide pipe 4, the air guide hole 41 on the first part 45 is blocked by the atomization substrate, and external air can enter along the air guide hole 41 on the second part 46 and then flow to the second liquid storage cavity 31 through the second air passage, thereby ensuring the reliability of the air supply to the second liquid storage cavity 31 when the atomization substrate flows out of the second liquid storage cavity 31.

[0068] In the embodiments of the present application, when the atomization device is in the first flat state or the second flat state, the gas-liquid layering in the second liquid storage cavity 31, the first air passage and the second air passage corresponding to the air layer, and the separation of the gas path and the liquid path can all achieve liquid supply to the atomization assembly 5, can improve the reliability and convenience of liquid supply to the atomization assembly 5, and can improve the user experience. Moreover, the second liquid storage cavity 31 can be supplied with air in time, the direct discharge of high-temperature and low-temperature air can be avoided, and the oil squeezing phenomenon can be prevented.

[0069] In some embodiments, along the thickness direction of the atomization device, the liquid guide pipe 4 can include opposite first and second parts 45 and 46. When the atomization device is placed flat, the atomization substrate in the second liquid storage cavity 31 can first flow into the liquid guide pipe 4 from the second end 44 and then flow to the atomization core 52 from the liquid guide hole 42 on the first end 43. The atomization substrate can first flow in the length direction of the atomization device and then flow in the width direction of the atomization device.

[0070] In some embodiments, after the external air enters the first liquid storage cavity 11, it passes through the hole bubbles in the liquid guide element 51 and then enters the liquid guide pipe 4 from the air guide hole 41 and is then transmitted to the second liquid storage cavity 31.

[0071] In some embodiments, the first part 45 and the second part 46 are both provided with liquid guide holes 42; in the first flat state, the liquid guide holes 42 on the second part 46 are in communication with the atomization assembly 5; and in the second flat state, the liquid guide holes 42 on the first part 45 are in communication with the atomization assembly 5.

[0072] In the embodiments of the present application, when the atomization device is in the first flat state, the atomization substrate in the second liquid storage cavity 31 can flow to the first liquid storage cavity 11 along the second part 46 of the liquid guide pipe 4, so that the atomization substrate can flow to the atomization assembly 5 from the liquid guide hole 42 on the second part 46 by gravity, and the reliability of oil supply to the atomization assembly 5 can be improved.

[0073] When the atomization device is in the second flat state, the atomization substrate in the second liquid storage cavity 31 can flow to the first liquid storage cavity 11 along the first part 45 of the liquid guide pipe 4, so that the atomization substrate can flow to the atomization assembly 5 from the liquid guide hole 42 on the first part 45 by gravity, and the reliability of oil supply to the atomization assembly 5 can be improved.

[0074] In some embodiments of the present application, the number of the air guide holes 41 is at least two, and the at least two air guide holes 41 are distributed along the circumference of the liquid guide pipe 4, and the diameter of the air guide hole 41 ranges from 0.5 mm to 0.8 mm.

[0075] In the embodiments of the present application, the diameter of the air guide hole 41 is controlled to range from 0.5 mm to 0.8 mm, so that the air guide hole 41 has a small aperture, and when the atomization device is vertically placed, an oil film is easily formed in the air guide hole 41, and when the atomization device is horizontally placed, a negative pressure is generated by the flow of the atomization substrate in the second liquid storage cavity 31, the oil film at the air guide hole 41 is broken, so that air can pass through the air guide hole 41, and the liquid path and the gas path can be prevented from interfering with each other. The number of the air guide holes 41 is designed to be at least two, which can ensure that the air guide hole 41 can pass a certain amount of gas, so that the atomization substrate in the second liquid storage cavity 31 can flow out while sufficient gas enters the second liquid storage cavity 31, thereby satisfying the smoothness of the flow of the atomization substrate.

[0076] For example, the number of the air guide holes 41 can be two, three, four, six, or eight, etc. Figure 4 As shown, the first part 45 of the liquid guide pipe 4 is provided with three air guide holes 41, and the second part 46 is also provided with three air guide holes 41, and other cases can be referred to the design, which is not limited in the embodiments of the present application.

[0088] In the embodiment of the present application, the liquid absorbing element 7 covers the air outlet hole 121, can absorb the atomized substrate leaked from the air outlet hole 121, avoid being sucked by the suctioner through the air inlet channel 61, and improve the taste. Since the liquid absorbing element 7 has air permeability, it is also convenient for the liquid absorbing element 7 to guide the gas into the air outlet hole 121, so that the gas can be smoothly transmitted to the second liquid storage cavity 31.

[0089] In some embodiments, the liquid absorbing element 7 can be oil absorbing cotton, oil storage cotton or high polymer cotton, or can also be PET material, so that the liquid absorbing element 7 has the characteristics of air permeability.

[0093] In the embodiment of the present application, the second end of the liquid guide pipe is communicated with the second liquid storage cavity, and the first end is communicated with the atomization assembly through the liquid guide hole, so that the atomized substrate can flow out of the second liquid storage cavity, be transmitted through the liquid guide pipe, and be transmitted to the atomized substrate in the first liquid storage cavity from the liquid guide hole, and then the atomization assembly atomizes the atomized substrate to obtain the aerosol. Since the air guide hole is communicated with the outside through the first liquid storage cavity, when the atomized substrate flows from the second liquid storage cavity to the atomization assembly, the air outside can pass through the air guide hole from the first liquid storage cavity and then be transmitted to the second liquid storage cavity by the liquid guide pipe, and the air exchange path and the liquid inlet path are independently arranged, that is, the second liquid storage cavity can be supplemented with air in time while the atomized substrate flows out of the second liquid storage cavity, so as to balance the pressure in the second liquid storage cavity, which can improve the reliability and stability of providing the atomization assembly with the atomized substrate, and then facilitate the reasonable arrangement of the size of the liquid guide hole, avoid being too large or too small, meet a certain suction port number, and also avoid a paste core.
