[0028] Please refer to Figure 1 and Figure 2 The present invention provides an electronic atomizer 100 , which includes a housing 10 , an atomizing tube 20 , an atomizing core 30 , a heating element 40 and a switching switch 50 .

[0029] Optionally, the housing 10 may be cylindrical or columnar, without limitation. The wall thickness of the housing 10 may be substantially uniform throughout. The housing 10 may be a one-piece structure, and the one-piece molding process may be stamping, casting, etc., without limitation. The housing 10 may also be a split structure, and the various parts of the housing 10 may be connected and fixed by welding, bonding, clamping, screwing, etc.

[0030] The atomizing tube 20 is disposed in the housing 10 . The outer surface of the atomizing tube 20 and the inner wall of the housing 10 enclose a liquid storage chamber 60 . The atomizing tube 20 further defines an oil inlet 21 , and the liquid storage chamber 60 is communicated with the oil inlet 21 .

[0031] The atomizing pipe 20 can be a one-piece structure or can be formed by sequentially splicing multiple pipe sections. The connection between the multiple pipe sections can be welding, bonding, clamping, screwing, etc., without limitation. The atomizing pipe 20 can extend along a straight line, a curve, or a broken line, without limitation.

[0032] The atomizer core 30 is received in the atomizer tube 20 and closes the oil inlet 21 . The heater 40 is received in the liquid storage chamber 60 and disposed adjacent to the oil inlet 21 . The heater 40 is used to heat the liquid in the liquid storage chamber 60 .

[0033] The atomizer core 30 is a commonly used atomizer in the art, such as a ceramic atomizer core, a cotton core atomizer core, etc. It can be a single heating wire atomizer core, a double heating wire atomizer core, a multi-heating wire atomizer core, etc., without specific limitation.

[0034] Optionally, there can be one or more atomizer cores 30. Multiple atomizer cores 30 can operate independently or be connected in parallel for ease of control. Multiple atomizer cores 30 can be arranged sequentially and spaced apart along the extension direction of the atomizer tube 20 or arranged side by side without limitation.

[0035] Optionally, the atomizer core 30 encloses an airflow channel 31 that communicates with the atomizer tube 20. Atomized gas enters the atomizer tube 20 through the airflow channel 31, facilitating inhalation by the user. The outer surface of the atomizer core 30 is in close contact with the inner surface of the atomizer tube 20 to prevent the atomized liquid passing through the oil inlet 21 from leaking between the outer surface of the atomizer core 30 and the inner surface of the atomizer tube 20.

[0036] Optionally, the atomizer core 30 includes an atomizing portion and a heating wire 75. The atomizing portion seals the oil inlet 21 and encloses the airflow channel 31. The heating wire 75 is disposed within the atomizing portion and is used to atomize the atomized liquid. The heating wire 75 of the atomizer core 30 is electrically connected to the circuit board 51 of the electronic atomizer 100 via a connecting wire 76.

[0037] The heating element 40 can be a ceramic heating element, or a metal heating wire, a heating film, a heating mesh, etc., without limitation. The heating element 40 can be a ring-shaped, sheet-shaped structure, etc., without limitation.

[0038] Optionally, the housing 10 and the atomizing tube 20 may be an integral structure, and the integral molding process may be stamping, casting, etc., without limitation.

[0039] The switch 50 is electrically connected to the atomizer core 30 and the heater 40. The switch 50 is used to switch one of the atomizer core 30 and the heater 40 into an operating state. The specific shape of the switch 50 can refer to any feasible solution and is not specifically limited in the embodiment of the utility model.

[0040] Optionally, the switch 50 is a self-locking button switch. The self-locking button switch can automatically remain in the on state (i.e., self-locking) after being pressed, and will not disconnect until it is pressed again. When the user needs to heat the liquid to be atomized, the switch 50 is in the first state, so that the heating element 40 is in the working state, and the liquid to be atomized near the oil inlet 21 is preheated to reduce the viscosity of the liquid to be atomized near the oil inlet 21, so that the fluidity of the liquid to be atomized near the oil inlet 21 is better, ensuring sufficient liquid supply to the atomizing core 30, and avoiding dry burning and burnt smell; when the user needs to atomize the liquid to be atomized, the switch 50 is in the second state, so that the atomizing core 30 is in the working state, and the atomized liquid is atomized. Setting the switch 50 can switch between the above two working states, which has a simple structure, low cost, and is easy to use.

[0041] The electronic atomizer 100 in the embodiment of the present invention is provided with an atomizing core 30, a heating element 40 and a switching switch 50. The switching switch 50 can enable the electronic atomizer 100 to switch between two working states: heating and atomizing. In the heating state, the heating element 40 preheats the liquid to be atomized near the oil inlet 21 to reduce the viscosity of the liquid to be atomized near the oil inlet 21, avoid dry burning of the atomizing core 30, and improve the atomization effect; in the atomizing state, the atomizing core 30 atomizes the liquid to be atomized, and the atomization is sufficient. The switching operation between the two working states is simple.

[0042] In one embodiment, Figure 2 As shown, the shell 10 includes a first end face 11 and a second end face 12 opposite to each other, the atomizer tube 20 extends from the first end face 11 to the second end face 12, the oil inlet 21 is closer to the first end face 11 than the second end face 12, and the heating element 40 is closer to the first end face 11 than the oil inlet 21.

[0043] First define the direction. Figure 2 As shown, the Z direction is the height direction of the electronic atomizer 100.

[0044] Optionally, the atomizing tube 20 extends along the Z direction, and the first end face 11 and the second end face 12 are opposite to each other in the Z direction. When in use, that is, when the Z direction is roughly parallel to the direction of gravity, the first end face 11 is closer to the ground. The oil inlet 21 is closer to the first end face 11 than the second end face 12, that is, the oil inlet 21 is arranged near the bottom of the atomizing tube 20, and the utilization rate of the liquid to be atomized in the liquid storage chamber 60 is high, and it will not be wasted due to the inability to enter the oil inlet 21. The heating element 40 is closer to the first end face 11 than the oil inlet 21, and the heating element 40 is roughly located at the bottom of the liquid storage chamber 60. The liquid to be atomized near the oil inlet 21 can enter the atomizing core 30 through the oil inlet 21 in time after being heated, further ensuring sufficient liquid supply to the atomizing core 30.

[0045] By providing the housing 10 with the first end face 11 and the second end face 12 facing each other, the oil inlet 21 is closer to the first end face 11 than the second end face 12, and the heating element 40 is closer to the first end face 11 than the oil inlet 21. The utilization rate of the liquid to be atomized in the liquid storage chamber 60 is high, and the liquid to be atomized will not be wasted due to being unable to enter the oil inlet 21. After being heated by the heating element 40, the liquid to be atomized near the oil inlet can enter the atomizer core 30 through the oil inlet 21 in a timely manner, further ensuring sufficient liquid supply to the atomizer core 30.

[0046] In one embodiment, Figure 2 As shown, the end of the oil inlet 21 close to the first end surface 11 is flush with the end surface of the heating element 40 away from the first end surface 11. In this way, the liquid to be atomized in the liquid storage chamber 60 will not accumulate between the oil inlet 21 and the heating element 40 to cause waste, and the utilization rate of the liquid to be atomized is high.

[0047] In one embodiment, Figure 2 As shown, there is a gap between the heater 40 and the atomizer tube 20. The size of this gap can be 1mm, 2mm, 3mm, 4mm, 5mm, etc., and can be determined according to actual needs without limitation. By providing a gap between the heater 40 and the outer surface of the atomizer tube 20, the heat generated by the heater 40 during operation is prevented from affecting the atomizer tube 20.

[0048] In one embodiment, the heating element 40 is annular, and there are multiple oil inlets 21 , which are annularly spaced apart and opened in the atomizing tube 20 .

[0049] Optionally, the heating element 40 is a single, annular element, and the distance from the atomizer tube 20 to each circumferential location of the heating element 40 is approximately the same. That is, when the atomizer tube 20 is cylindrical, the axis of the atomizer tube 20 and the axis of the heating element 40 are approximately aligned. Multiple oil inlets 21 are spaced circumferentially along the atomizer tube 20, and the distance between adjacent oil inlets 21 can be the same or different, without limitation.

[0050] In another embodiment, multiple heating elements 40 are provided and spaced circumferentially around the atomizing tube 20. The distance between adjacent heating elements 40 can be the same or different, without limitation. Alternatively, the number of heating elements 40 corresponds to the number of oil inlets 21, i.e., a heating element 40 is provided near each oil inlet 21.

[0051] By configuring the heating element 40 to be annular, and with multiple oil inlets 21 spaced apart along the annular direction on the atomizer tube 20 , the atomizer liquid is uniformly preheated by the heating element 40 along the circumference of the atomizer tube 20 before entering the atomizer core 30 , thereby preventing uneven heating that could cause localized dry burning of the atomizer core 30 .

[0052] In one embodiment, Figure 2As shown, the electronic atomizer 100 further includes a sealing member 70 , which is disposed between the housing 10 and the atomizing tube 20 and together with the inner wall of the housing 10 and the outer surface of the atomizing tube 20 , encloses a liquid storage chamber 60 .

[0053] Optionally, the sealing member 70 is a silicone member commonly used in the art. The material of the sealing member 70 can be silicone rubber, nitrile rubber (NBR), fluororubber, polytetrafluoroethylene (PTFE), etc., without limitation.

[0054] Optionally, the seal 70 may be connected to the housing 10 and the atomizing tube 20 by bonding, clamping, screwing, or the like, without limitation. The seal 70 abuts against the inner wall of the housing 10 and the outer surface of the atomizing tube 20 to prevent the atomized liquid from accumulating in the gap between the seal 70 and the inner wall of the housing 10 or the gap between the seal 70 and the outer surface of the atomizing tube 20.

[0055] The sealing member 70 is closer to the first end face 11 than the second end face 12 . The sealing member 70 defines a receiving groove 71 , in which the heating member 40 is received. At least a portion of the surface of the heating member 40 facing the second end face 12 is exposed to the liquid storage chamber 60 through the receiving groove 71 .

[0056] The shape of the receiving groove 71 can be block-shaped, disc-shaped, ring-shaped, etc., corresponding to the shape and number of the heating element 40, and is not specifically limited. Optionally, the inner wall surface of the receiving groove 71 abuts the surface of the heating element 40 to avoid accumulation of the atomized liquid.

[0057] The connection between the heating element 40 and the sealing member 70 can be by bonding, clamping, or the like, without limitation. The surface of the heating element 40 facing the second end surface 12 can be completely exposed from the receiving groove 71, i.e., the sealing member 70 does not block the surface of the heating element 40 facing the second end surface 12; alternatively, the sealing member 70 blocks at least a portion of the surface of the heating element 40 facing the second end surface 12, i.e., the sealing member 70 clamps the heating element 40 to secure the position of the heating element 40.

[0058] The sealing member 70 and the heating member 40 together form the bottom wall of the liquid storage chamber 60, thereby fully utilizing the liquid to be atomized within the liquid storage chamber 60 without causing waste. At least a portion of the surface of the heating member 40 facing the second end surface 12 is exposed from the receiving groove 71 to the liquid storage chamber 60, thereby heating the liquid to be atomized within the liquid storage chamber 60 near the oil inlet 21.

[0059] By providing a sealing member 70, the sealing member 70, the inner wall of the housing 10, and the outer surface of the atomizing tube 20 are collectively enclosed to form a liquid storage chamber 60. The heating element 40 is accommodated in a receiving groove 71 of the sealing member 70, and at least a portion of the surface of the heating element 40 facing the second end face 12 is exposed from the receiving groove 71 to the liquid storage chamber 60. The sealing member 70 seals the liquid storage chamber 60 to prevent the liquid to be atomized from leaking or accumulating, thereby preventing waste.

[0060] In one embodiment, Figure 2 As shown, the sealing member 70 includes a main body 72 and an annular edge 73, a receiving groove 71 is opened in the main body 72, the annular edge 73 is connected to the end of the main body 72 facing away from the first end face 11, and protrudes from the first end face 11, the annular edge 73, the main body 72 and the heating element 40 together enclose a flow groove 74, and the flow groove 74 is connected to the oil inlet 21.

[0061] The sealing member 70 may be an integral structure, and the integral molding process may be calendering, injection molding, etc., without limitation. The sealing member 70 may also be a split structure, and the main body 72 and the ring edge 73 may be connected and fixed by bonding, clamping, etc.

[0062] Optionally, the annular edge 73 blocks at least a portion of the surface of the heating element 40 facing the second end surface 12 to secure the heating element 40. The main body 72 abuts the outer surface of the atomizing tube 20 to prevent the atomized liquid from leaking out through the gap between the main body 72 and the atomizing tube 20. The annular edge 73 is spaced apart from the outer surface of the atomizing tube 20 to allow the heating element 40 to be exposed from the receiving groove 71 to the liquid storage chamber 60.

[0063] The liquid to be atomized near the oil inlet 21 will first enter the circulation groove 74. When the heating element 40 is working, it can preheat the liquid to be atomized in the circulation groove 74 to reduce the viscosity of the liquid to be atomized near the oil inlet 21. This makes the liquid to be atomized in the circulation groove 74 more fluid, ensures sufficient liquid supply to the atomizer core 30, and avoids dry burning.

[0064] The sealing member 70 includes a main body 72 and an annular edge 73 . The annular edge 73 , the main body 72 , and the heating member 40 together enclose a flow groove 74 . The flow groove 74 is connected to the oil inlet 21 . Before the atomized liquid enters the oil inlet 21 , it can be preheated by the heating member 40 in the flow groove 74 . This can reduce the viscosity of the atomized liquid and ensure sufficient liquid supply to the atomizing core 30 .

[0065] In one embodiment, Figure 2 As shown, the end surface of the main body 72 away from the first end surface 11 is flush with the end of the oil inlet 21 close to the first end surface 11. In this way, the liquid to be atomized in the liquid storage chamber 60 will not be accumulated between the oil inlet 21, the main body 72 and the heating element 40 to cause waste, and the utilization rate of the liquid to be atomized is high.

[0066] In one embodiment, the electronic atomizer 100 further includes a controller (not shown in the figure), which is electrically connected to the switch 50. The controller is used to receive a signal from the switch 50 and control the atomizer core 30 or the heating element 40 to be in an operating state.

[0067] Optionally, the controller may be a commonly used control device in the art, and the embodiment of the present utility model does not impose any specific limitation thereto.

[0068] Optionally, the electronic atomizer further includes a circuit board 51 (e.g., a PCB), and the controller is disposed on the circuit board 51. The switch 50 is electrically connected to the circuit board 51. When the switch 50 is pressed by the user, it contacts corresponding contacts on the circuit board 51 to send a corresponding signal to the controller. The controller controls the operation of the atomizer core 30 or the heater 40 according to the signal from the switch 50.

[0069] By setting a controller, the controller is used to control the atomizing core 30 or the heating element 40 to be in a working state to atomize the atomized liquid or preheat the atomized liquid, and the switching between the two working states is convenient.

[0070] In one embodiment, Figure 2 As shown, the electronic atomizer 100 also includes a base 80 and a nozzle 90. The base 80 is connected to the first end face 11. The base 80 has a receiving space 81, and the switching switch 50 and the controller are accommodated in the receiving space 81; the nozzle 90 is connected to the second end face 12, and the atomizing tube 20 is connected to the nozzle 90.

[0071] The specific shapes of the base 80 and nozzle 90 can be determined by any feasible method and are not specifically limited by the present embodiment. The base 80 and housing 10 can be connected by welding, bonding, snapping, screwing, magnetic connection, etc., without limitation. The nozzle 90 and housing 10 can be connected by welding, bonding, snapping, screwing, magnetic connection, etc., without limitation.

[0072] Optionally, at least a portion of the switch 50 is exposed from the base 80 to the outside space for easy user operation. Optionally, the switch includes a connecting portion and a touch portion connected to each other, the connecting portion being electrically connected to the circuit board 51, the touch portion being exposed from the base 80 to the outside space, and the touch portion being movable relative to the connecting portion. When in use, the user applies pressing pressure to the touch portion to move the touch portion relative to the connecting portion, thereby causing the switch 50 to contact the contacts on the circuit board 51 and send a signal to switch one of the atomizer core 30 and the heater 40 to the working state.

[0073] Optionally, the electronic atomizer 100 further includes a battery assembly (not shown) and a plug-in portion 82. The plug-in portion 82 is arranged on a side of the base facing away from the shell. The plug-in portion 82 is used to electrically connect to the battery assembly to power the electronic atomizer.

[0074] Optionally, the mouthpiece 90 has an air guide channel 91, which is connected to the atomizing tube 20. The gas atomized by the atomizing core 30 enters the air guide channel 91 of the mouthpiece 90 through the atomizing tube 20 and is inhaled by the user through the air guide channel 91.

[0075] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship of terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" is based on the orientation or positional relationship described in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
