[0027] In the embodiments of the present application, please refer to Figures 2 to 5 The liquid cup component 10 for the electronic atomization device 100 includes a cup body 101 and a cup sleeve 102; the cup body 101 is provided with a liquid storage cavity 111s and a liquid outlet hole 111h communicating with the liquid storage cavity 111s, the liquid storage cavity 111s is used for storing an atomizable liquid matrix, and the liquid outlet hole 111h is used for the liquid matrix in the liquid storage cavity 111s to flow out and further flow to the atomization element 20 for atomization; the cup sleeve 102 is sleeved on the cup body 101 and surrounds at least part of the liquid storage cavity 111s, and the cup sleeve 102 is provided with a viewing window 102w for observing the remaining liquid amount of the liquid storage cavity 111s; the viewing window 102w is transparent, and the part of the cup body 101 corresponding to the viewing window 102w is transparent. Through the liquid cup component 10, the cup body 101 and the cup sleeve 102 of the liquid cup component 10 form a split design, relative to the single-layer structure of the liquid cup component 10 in the prior art, the wall thickness H of the viewing window 102w is reduced, the processing and forming convenience of the viewing window 102w is improved, and the risk of defective products is reduced. When the cup sleeve 102 is formed by injection molding, the thickness of the viewing window 102w is reduced to reduce the deformation amount of the cup sleeve 102, improve the assembly operability of the viewing window 102w and the shell, reduce the risk of thickness printing (also known as stress marks, usually appearing on the appearance surface of the injection molded product, showing a kind of bright printing) and air holes, and improve the visibility of the viewing window 102w itself.

[0030] In some embodiments, the liquid cup component 10 further comprises a liquid injection plug 103 closing the liquid injection hole 112h. When the liquid matrix in the liquid storage cavity 111s is used up, the liquid injection plug 103 can be removed to expose the liquid injection hole 112h, so that the liquid matrix can be injected into the liquid storage cavity 111s through the liquid injection hole 112h. In addition, the liquid injection hole 112h can be closed through the liquid injection hole 112h, so as to prevent the liquid matrix in the liquid storage cavity 111s from leaking or being contaminated.

[0031] In some embodiments, the liquid injection hole 112h and the liquid outlet hole 111h are oppositely arranged, and the liquid injection hole 112h is used to correspond to the suction nozzle 41 of the electronic atomization device 100. Generally, the end where the liquid injection hole 112h is located is the top end of the liquid cup component 10, and the end where the liquid outlet hole 111h is located is the bottom end of the liquid cup component 10.

[0032] In some embodiments, please refer to Figure 6 The outer wall of the cup body 101 is provided with a limiting portion 1011, and along the assembly direction D1 of the cup sleeve 102 sleeved on the cup body 101, the cup sleeve 102 abuts against the limiting portion 1011. Through the arrangement of the limiting portion 1011, the structural stability of the cup sleeve 102 sleeved on the cup body 101 is improved.

[0033] Generally, the cup sleeve 102 is sleeved on the cup body 101 from the top end of the liquid cup component 10, i.e., the assembly direction D1 is the direction from the top end of the liquid cup component 10 to the bottom end of the liquid cup component 10.

[0034] In some embodiments, please refer to Figure 3 and Figure 6The limiting portion 1011 comprises a first section 1011a, a second section 1011b, a third section 1011c and a fourth section 1011d connected in sequence; the cup sleeve 102 comprises a first portion 1021, a second portion 1022, a third portion 1023 and a fourth portion 1024 connected in sequence, which enclose a sleeve shape; the first portion 1021 abuts against the first section 1011a, the second portion 1022 abuts against the second section 1011b, the third portion 1023 abuts against the third section 1011c, and the fourth portion 1024 abuts against the fourth section 1011d; along the assembly direction D1, the length of the second portion 1022 and the length of the fourth portion 1024 are both greater than the length of the first portion 1021 and the length of the third portion 1023. It can be understood that the first section 1011a, the second section 1011b, the third section 1011c and the fourth section 1011d of the limiting portion 1011 respectively adapt to the shape of the first portion 1021, the second portion 1022, the third portion 1023 and the fourth portion 1024 of the cup sleeve 102, further improving the structural stability of the cup sleeve 102 sleeved on the cup body 101.

[0035] It can be understood that in some embodiments, the first portion 1021 and the third portion 1023 are symmetrically arranged, and the second portion 1022 and the fourth portion 1024 are symmetrically arranged.

[0036] It is worth noting that in some embodiments, the number of windows 102w is two, one of which is located in the second portion 1022, and the other is located in the fourth portion 1024. That is, in the cup sleeve 102, along the assembly direction D1, the length of the second portion 1022 or the fourth portion 1024 used to set the window 102w is greater than the length of the first portion 1021 and the third portion 1023, so as to facilitate the flexibility of the length design of the window 102w.

[0037] In some embodiments, referring to Figure 6 and Figure 7 , the outer wall of the cup body 101 is provided with a limiting protrusion 1012, and the inner wall of the cup sleeve 102 is provided with a limiting groove 102s, the limiting protrusion 1012 is accommodated in the limiting groove 102s, so that the cup sleeve 102 is kept on the cup body 101. Through the limiting protrusion 1012 and the limiting groove 102s, the structural stability of the cup sleeve 102 sleeved on the cup body 101 is improved.

[0038] In some embodiments, the limiting protrusion 1012 comprises a first inclined surface 1012f, and the inner wall of the cup sleeve 102 is provided with a second inclined surface 102f, which is used to contact and guide the first inclined surface 1012f during the sleeving of the cup sleeve 102 on the cup body 101. Through the arrangement of the first inclined surface 1012f and the second inclined surface 102f, the cup sleeve 102 is facilitated to be sleeved on the cup body 101.

[0039] In some embodiments, the number of limiting grooves 102s is two, one of which is located in the first part 1021, and the other of which is located in the third part 1023, and the two limiting grooves 102s can be symmetrically arranged. It can be understood that the number of limiting protrusions 1012 is two, one of which extends into one of the limiting grooves 102s, and the other of which extends into the other limiting groove 102s. Through the arrangement of the two limiting grooves 102s and the two limiting protrusions 1012, the structural stability of the cup sleeve 102 sleeved on the cup body 101 is further improved.

[0040] In some embodiments, the cup body 101 is transparent, and the cup sleeve 102 is transparent, that is, not only the window 102w in the cup sleeve 102 is transparent, but also the cup sleeve 102 as a whole is transparent and the cup body 101 as a whole is transparent.

[0041] In some embodiments, the window 102w protrudes from the side of the cup sleeve 102 away from the cup body 101, or the wall thickness of the window 102w is greater than that of the rest of the cup sleeve 102, so as to facilitate the observation of the remaining liquid amount in the liquid storage cavity 111s through the window 102w.

[0042] In some embodiments, referring to Figure 5 and Figure 6 , the cup body 101 is further provided with an atomization channel 112s, and the atomization channel 112s communicates with the liquid outlet hole 111h. Through the atomization channel 112s, the smoke generated by heating and atomization of the atomization element 20 arranged at the liquid outlet hole 111h can enter the suction nozzle 41 of the electronic atomization device 100 through the atomization channel 112s for the user to inhale.

[0043] In some embodiments, the number of atomization channels 112s is two, and the two atomization channels 112s are distributed on both sides of the cup body 101 and on both sides of the liquid storage cavity 111s.

[0044] In some embodiments, referring to Figure 5 and Figure 6The cup body 101 includes a main body 1011 and a support 1012. The main body 1011 is provided with a liquid storage chamber 111s and an injection hole 112h and an installation port 113h that are connected to the liquid storage chamber 111s and are arranged opposite each other in the longitudinal direction. The support 1012 closes the installation port 113h, and the liquid outlet hole 111h is limited on the support 1012. The cup sleeve 102 is sleeved on the main body 1011. With this design, the main body 1011 and the support 1012 of the cup body 101 of the liquid cup component 10 are designed as separate parts. Compared with the existing one-piece molded structure of the liquid cup component 10, the main body 1011 and the support 1012 can be demolded separately during the manufacturing of the liquid cup component 10. Furthermore, the demolding direction of the main body 1011 of the liquid cup component 10 can avoid the end where the injection hole 112h is located, and instead select the mounting port 113h where the support 1012 is located as the demolding port. Therefore, when the injection hole 112h corresponds to the nozzle 41 of the electronic atomizing device 100, the dimensional flexibility of the nozzle 41 can be improved, and the size of the nozzle 41 does not need to be designed to be large. In addition, when the mounting port 113h is used as the demolding port, it is not necessary to demold from the injection hole 112h, so the size of the injection hole 112h can be set to be smaller, which facilitates the sealing of the injection hole 112h.

[0045] The assembly direction D1 of the cup sleeve 102 being fitted onto the cup body 101 is the longitudinal direction of the electronic atomizing device.

[0046] This application also provides an electronic atomizing device 100, such as... Figure 4 and Figure 5 As shown, the electronic atomizing device 100 includes the liquid cup component 10 and the atomizing element 20. The atomizing element 20 is used to atomize the liquid matrix originating from the liquid storage chamber 111s to generate an aerosol. For the specific structure and function of the liquid cup component 10, please refer to the above embodiments, which will not be repeated here.

[0047] In some embodiments, the electronic atomization device 100 further comprises at least an electrode element 30, a housing 40, a circuit board 50, and a power supply 60. The atomization element 20, the electrode element 30, the circuit board 50, the power supply 60, and the liquid cup component 10 are all accommodated in the housing 40. The housing 40 is provided with a suction nozzle 41 and a connecting portion 42, the connecting portion 42 is pressed against the liquid injection plug 14, the suction nozzle 41 is opposite to the side of the connecting portion 42 away from the liquid injection plug 14, and the suction nozzle 41 communicates with the atomization channel 112s. The atomization element 20 is arranged on the side of the cup body 101 away from the suction nozzle 41, the atomization element 20 closes the liquid outlet hole 111h, and the electrode element 30 is arranged on the side of the atomization element 20 away from the cup body 101, i.e. the cup body 101 and the atomization element 20 are both supported by the electrode element 30, and the cup body 101 bears the pressure of the atomization element 20 and the electrode element 30. The electrode element 30 is connected to the circuit board 50, the circuit board 50 is connected to the power supply 60, and the power supply 60 supplies power to the atomization element 20 to heat and atomize the liquid substrate entering from the liquid outlet hole 111h of the cup body 101, and the smoke generated by heating and atomizing the liquid substrate enters the suction nozzle 41 from the atomization channel 112s for the user to inhale.
