Description

The differential pressure detection component has a first detection end and a second detection end. The first detection end communicates with the atomization channel, and the second detection end communicates with the external environment.

[0003] When the electronic atomization device is in use, the user sucks out the gas in the atomization channel through the mouthpiece.

[0042] As described in the background art, currently, an electronic atomization device is an atomization device driven by electricity, mainly used to convert an aerosol matrix into an aerosol. The electronic atomization device in the related art includes an atomizer and a differential pressure detection component. Among them, the atomizer can convert the aerosol matrix into an aerosol. The atomizer has an atomization channel and a mouthpiece communicated with the atomization channel; the differential pressure detection component is located on one side of the atomizer and is electrically connected to the atomizer. The differential pressure detection component has a first detection end and a second detection end. The first detection end is communicated with the atomization channel, and the second detection end is communicated with the external environment. When the electronic atomization device is in use, the user sucks out the gas in the atomization channel through the mouthpiece. Since the first detection end is communicated with the atomization channel, the air pressure at the first detection end will decrease. At the same time, since the second detection end is communicated with the external environment, the air pressure at the second detection end will always be the same as the atmospheric pressure; after the differential pressure detection component detects this differential pressure change, it will send a start signal to the atomizer through the controller to make the atomizer start to work. However, since the first detection end is communicated with the atomization channel, the condensate of the aerosol generated in the atomization channel easily penetrates into the differential pressure detection component through the first detection end, resulting in damage to the differential pressure detection component.

[0043] Referring to Figures 1 to 6 , to solve the above problems, according to one aspect of the present application, an embodiment of the present application provides an electronic atomization device, which includes an atomizer 100, a start pipeline 200, and a differential pressure detection part 300. Among them, the atomizer 100 has an atomization channel 110 capable of converting an aerosol matrix into an aerosol; the start pipeline 200 has a start airway 210. The start airway 210 is independent of the atomization channel 110, and the gas in the start airway 210 can be sucked out; the differential pressure detection part 300 is located on one side of the atomizer 100 and is electrically connected to the atomizer 100; the differential pressure detection part 300 has a first detection end 310 and a second detection end 320. The first detection end 310 is communicated with the start airway 210, and the second detection end 320 is communicated with the external atmospheric environment; after the differential pressure detection part 300 detects a pressure difference between the air pressure at the first detection end 310 and the air pressure at the second detection end 320, the atomizer 100 starts.

[0044] In the embodiment of the present application, the atomization channel 110 is communicated with the external atmospheric environment, and at the same time, the gas in the atomization channel 110 can be sucked out; the start airway 210 and the atomization channel 110 belong to two independent channels and do not interfere with each other; the differential pressure detection part 300 is a pressure switch or a differential pressure sensor. The first detection end 310 and the second detection end 320 are usually arranged oppositely. The first detection end 310 is used to detect the air pressure in the start airway 210, and the second detection end 320 is used to detect the air pressure of the external atmospheric environment. Figure 3The two line segments with solid arrows respectively represent the gas flow directions in the atomization channel 110 and the starting air passage 210.

[0045] When using the electronic atomization device of the present application, first, the gas in the starting air passage 210 is sucked outwards. During this process, the air pressure in the starting air passage 210 will decrease, and the air pressure at the first detection end 310 will also decrease accordingly; at the same time, since the second detection end 320 is connected to the external atmospheric environment, the air pressure at the second detection end 320 will remain unchanged; after the differential pressure detection part 300 detects a pressure difference between the air pressure at the first detection end 310 and the air pressure at the second detection end 320, the atomizer 100 will be started accordingly, and the aerosol matrix will also be converted into aerosol in the atomization channel 110. The starting air passage 210 and the atomization channel 110 in the present application are independent of each other, and at the same time, the design that the differential pressure detection part 300 is located on one side of the atomizer 100 makes the condensate of the aerosol generated in the atomization channel 110 unable to flow to the differential pressure detection part 300 through the atomization channel 110, so that the differential pressure detection part 300 cannot be damaged. The above design not only ensures the integrity of the differential pressure detection part 300, but also extends the service life of the differential pressure detection part 300.

[0046] Refer to Figure 3 、 Figure 5 and Figure 6 In an embodiment, the starting air passage 210 is located on one side of the atomization channel 110, and the gas in the starting air passage 210 and the gas in the atomization channel 110 can be sucked out simultaneously.

[0047] When using the electronic atomization device of the present application, the user will suck out the gas in the starting air passage 210 and the gas in the atomization channel 110 simultaneously. When the differential pressure detection part 300 detects a pressure difference between the air pressure at the first detection end 310 and the air pressure at the second detection end 320, not only the atomizer 100 will start to work, but also the air in the external atmospheric environment has been sucked into the atomization channel 110. On this basis, along with the start of the atomizer 100, the user can quickly suck out a large amount of aerosol from the atomization channel 110. The design that the gas in the starting air passage 210 and the gas in the atomization channel 110 can be sucked out simultaneously not only improves the sensitivity of the electronic atomization device, so that the suction action realizes zero delay, but also improves the use experience of the electronic atomization device.

[0048] Refer to Figure 3 、 Figure 4 and Figure 6 In an embodiment, the electronic atomization device further includes a control part 400. The differential pressure detection part 300 is installed on the control part 400, the differential pressure detection part 300 is electrically connected to the control part 400, and the atomizer 100 is electrically connected to the control part 400.

[0049] In this embodiment, the control unit 400 is a PCB (full English name: Printed Circuit Board, Chinese name: printed circuit board). The differential pressure detection unit 300 is usually fixedly installed on the control unit 400 by welding to facilitate electrical connection with the control unit 400. The provided control unit 400 not only functions to electrically connect the differential pressure detection unit 300 and the atomizer 100, but also functions to install and carry the differential pressure detection unit 300.

[0050] Referring to Figure 4 、 Figure 6 and Figure 7 , in an embodiment, the electronic atomization device further includes an isolation part 500. An isolation groove 510 is provided on the surface of the isolation part 500 close to the control unit 400. The isolation groove 510 is independent of the space outside the isolation part 500. The differential pressure detection unit 300 is located in the isolation groove 510. A first communication hole 520 is provided on the isolation part 500. The first communication hole 520 communicates with the isolation groove 510. The first detection end 310 communicates with the starting air passage 210 through the first communication hole 520. An air intake through hole 410 is provided on the control unit 400. The second detection end 320 communicates with the external atmospheric environment through the air intake through hole 410.

[0051] In this embodiment, the first detection end 310 is located on the side of the second detection end 320 away from the control unit 400. The isolation part 500 is an isolation cover or an isolation shell. The surface of the isolation part 500 close to the control unit 400 is kept in contact with the surface of the control unit 400 close to the isolation part 500. At the same time, the isolation groove 510 has an isolation opening and an isolation groove wall. The isolation groove wall is an annular groove wall connected end to end, so that the isolation groove 510 is independent of the space outside the isolation part 500 and does not interfere with each other. The differential pressure detection unit 300 is covered in the isolation groove 510. The first communication hole 520 is located on the side of the isolation groove 510 close to the starting air passage 210, so that the first detection end 310 communicates with the starting air passage 210 through the first communication hole 520. The air intake through hole 410 is located on the side of the isolation groove 510 away from the starting air passage 210, so that the second detection end 320 communicates with the external atmospheric environment through the air intake through hole 410. The isolation groove 510 in this application not only functions to isolate the differential pressure detection unit 300, ensuring the detection accuracy of the differential pressure detection unit 300, but also functions to protect the differential pressure detection unit 300. In addition, the surface of the differential pressure detection unit 300 close to the control unit 400 is kept in contact with the surface of the control unit 400 close to the differential pressure detection unit 300. An air outlet hole is further provided on the surface of the differential pressure detection unit 300 close to the starting air passage 210. The aperture of the air outlet hole is smaller than the aperture of the air intake through hole 410.

[0052] Referring to Figure 4 、Figure 6 and Figure 7 In one embodiment, a pressure stabilizing groove 530 is provided on the groove wall of the isolation groove 510 near the first detection end 310, and the first communication hole 520 communicates with the isolation groove 510 through the pressure stabilizing groove 530.

[0053] In this embodiment, the isolation groove 510 generally covers the pressure stabilizing groove 530, the pressure stabilizing groove 530 generally covers the first communication hole 520, and at the same time the pressure stabilizing groove 530 covers the air outlet hole. The provided pressure stabilizing groove 530 not only helps to guide the gas flow in the starting air passage 210 to the first detection end 310, so that the first detection end 310 accurately detects the air pressure in the starting air passage 210, but also helps to form a relatively stable pressure environment at the first detection end 310, weakening the interference of the pressure environment at the first detection end 310 caused by pressure pulsation or turbulence, etc., thus ensuring the detection accuracy of the differential pressure detection part 300.

[0054] Referring to Figure 4 In one embodiment, the differential pressure detection part 300 is in close contact with the groove wall of the isolation groove 510, and the pressure stabilizing groove 530 covers the first detection end 310. In this embodiment, the differential pressure detection part 300 is in interference fit with the groove wall of the isolation groove 510. The above design can effectively prevent the air in the external atmosphere from entering the first detection end 310 through the gap between the differential pressure detection part 300 and the groove wall of the isolation groove 510, thus ensuring the detection accuracy of the differential pressure detection part 300.

[0055] Referring to Figure 4 、 Figure 6 and Figure 7 In one embodiment, the atomizer 100 includes a mounting base 120, the mounting base 120 has a first connection structure, the isolation part 500 has a second connection structure, one of the first connection structure and the second connection structure is a first connection convex part 540, and the other is a first connection groove, and the isolation part 500 is connected to the mounting base 120 by inserting the first connection convex part 540 into the first connection groove.

[0056] In this embodiment, the first connection convex part 540 is a connection convex column or a connection convex block. The first connection convex column and the first connection groove used in cooperation in this application can not only install the isolation part 500 on the mounting base 120, so that the isolation part 500 is installed on the atomizer 100, but also help to reduce the volume of the assembled isolation part 500 and the mounting base 120, thus reducing the volume of the electronic atomization device.

[0057] Referring to Figure 4 、 Figure 6 and Figure 7, in one embodiment, the isolation part 500 is an elastic structure capable of elastic deformation; the first connection groove is provided on the mounting base 120, and the isolation part 500 has a first connection convex part 540; the first connection convex part 540 is inserted into the first connection groove and is in interference fit with the groove wall of the first connection groove; the first connection groove forms a first connection structure, and the first connection convex part 540 forms a second connection structure.

The isolation part 500 is an elastic structure capable of elastic deformation, and at the same time, the design of the interference fit between the first connection convex part 540 and the groove wall of the first connection groove strengthens the connection strength between the isolation part 500 and the mounting base 120, thereby improving the stability of the isolation part 500 mounted on the mounting base 120. In other embodiments, the mounting base 120 can also have a first connection convex part 540 that protrudes towards the control part 400, the first connection groove is provided on the surface of the isolation part 500 away from the control part 400, the first connection convex part 540 forms a first connection structure, and the first connection groove forms a second connection structure.

[0060] When the electronic atomization device of the present application is in use, the gas in the voltage stabilizing groove 530 will sequentially pass through the first communication hole 520, the second communication hole 121, and the mounting hole 131 and then enter the starting air passage 210, and finally be sucked out from the starting air passage 210; the first communication hole 520, the second communication hole 121, and the mounting hole 131 used in cooperation in the present application play a role in connecting the starting air passage 210 with the pressure difference detection part 300; the provided mounting bracket 130 plays a role in mounting and carrying the mounting base 120; the provided mounting bracket 130 plays a role in mounting and carrying the starting pipe 200.

[0061] Refer to Figure 3 , Figure 6 andFigure 8 In one embodiment, the mounting bracket 130 has a third connection structure, and the mounting base 120 has a fourth connection structure. One of the third connection structure and the fourth connection structure is the second connection convex part 122, and the other is the second connection groove.

[0062] In this embodiment, the second connection convex part 122 is a connection convex post or a connection convex block. The second connection convex post and the second connection groove used in cooperation in this application can not only mount the mounting bracket 130 on the mounting base 120, so that the starting pipe 200 is mounted on the mounting base 120, but also help to reduce the volume of the assembled mounting bracket 130 and the mounting base 120, thereby reducing the volume of the electronic atomization device.

[0065] Referring to Figure 3 , Figure 6 and Figure 8 , in one embodiment, the atomizer 100 has a liquid storage space 140. The starting pipe 200 has a first end that passes through the liquid storage space 140 and is inserted into the mounting hole 131. The starting pipe 200 is in interference fit with the hole wall of the mounting hole 131.

[0066] In this embodiment, the liquid storage space 140 is used to store the aerosol matrix. The design of the first end passing through the liquid storage space 140 and being inserted into the mounting hole 131 is beneficial to further reducing the volume of the electronic atomization device; the design of the interference fit between the starting pipe 200 and the hole wall of the mounting hole 131 can effectively prevent the liquid in the liquid storage space 140 from flowing into the mounting hole 131 through the gap between the starting pipe 200 and the hole wall of the mounting hole 131, playing a role in protecting the differential pressure detection part 300. In addition, to effectively reduce the corrosion of the starting pipe 200 by the aerosol matrix, the starting pipe 200 is a steel pipe.

[0067] Referring to Figures 1 to 3 and Figure 9, in one embodiment, the atomizer 100 further includes a mounting housing 150. A mouthpiece 151 is provided on the mounting housing 150, and the gas in the atomization channel 110 is sucked outwards through the mouthpiece 151. An air inlet hole 152 is provided on the mounting housing 150. The air inlet hole 152 is located on one side of the mouthpiece 151. The starting pipe 200 has a second end disposed opposite to the first end, and the second end is inserted into the air inlet hole 152. The starting air channel 210 is communicated with the air inlet hole 152, and the gas in the starting air channel 210 is sucked outwards through the air inlet hole 152.

[0068] In this embodiment, the second end is fixedly inserted into the air inlet hole 152. By adopting the mouthpiece 151 and the air inlet hole 152 in the present application, the user only needs to directly contact the mounting housing 150 to suck out the gas in the atomization channel 110 and the gas in the starting air channel 210. This is not only beneficial for the user to suck out the gas in the atomization channel 110 and the gas in the starting air channel 210 at the same time, but also does not require the user to directly contact the atomization channel 110 and the starting pipe 200, effectively improving the user experience.

[0069] Referring to Figure 3 and Figure 4 , in one embodiment, the electronic atomization device has a battery compartment 600. The battery compartment 600 is communicated with the external atmospheric environment, and the air inlet through-hole 410 is communicated with the external atmospheric environment through the battery compartment 600. An air inlet hole is provided on the mounting housing 150. The air inlet hole is independent of the air inlet through-hole 410 and is communicated with the external atmospheric environment. The atomization channel 110 is communicated with the external atmospheric environment through the air inlet hole.

[0070] In this embodiment, the air inlet hole is independent of the air inlet through-hole 410 and does not interfere with each other. This design in which the air inlet hole and the air inlet through-hole 410 are independent of each other can effectively prevent the condensate of the aerosol in the atomizer 100 from flowing to the differential pressure detection part 300 through the air inlet hole, further ensuring the integrity of the differential pressure detection part 300.

[0071] In summary, implementing the electronic atomization device provided in this embodiment has at least the following beneficial technical effects: When using the electronic atomization device of the present application, the gas in the starting air passage 210 is first sucked outwards. During this process, the air pressure in the starting air passage 210 will decrease, and the air pressure at the first detection end 310 will also decrease accordingly; at the same time, since the second detection end 320 is connected to the external atmospheric environment, the air pressure at the second detection end 320 will remain unchanged; after the differential pressure detection unit 300 detects a pressure difference between the air pressure at the first detection end 310 and the air pressure at the second detection end 320, the atomizer 100 will be started accordingly, and the aerosol matrix will also be converted into aerosol in the atomization channel 110. The starting air passage 210 and the atomization channel 110 in the present application are independent of each other, and the design that the differential pressure detection unit 300 is located on one side of the atomizer 100 makes the condensate of the aerosol generated in the atomization channel 110 unable to flow to the differential pressure detection unit 300 through the atomization channel 110, so that the differential pressure detection unit 300 cannot be damaged. The above design not only ensures the integrity of the differential pressure detection unit 300, but also extends the service life of the differential pressure detection unit 300.

[0072] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
