Technical Field

[0001] The present application relates to the technical field of atomizers, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] The electronic atomization device in the prior art is mainly composed of an atomizer and a battery assembly. The atomizer heats the liquid matrix and atomizes it to form an aerosol that can be consumed by the user, and the battery assembly is used to provide energy to the atomizer. Since the porous ceramic body has pores and has the functions of conducting and storing liquid, there are many porous ceramic bodies on the market as atomization cores. However, when there is too little liquid matrix in the pores of the atomization core, the atomization core is prone to dry burning, forming a burnt smell and self-damage due to high temperature. Summary of the invention

[0003] The present application mainly provides an atomizer and an electronic atomization device to solve the problem that the atomization core is prone to dry burning.

[0004] In order to solve the above technical problems, a technical solution adopted by the present application is to provide an atomizer. The atomizer includes: an atomizer core; a temperature-sensitive magnetic part fixed on the atomizer core; an electrode movably arranged relative to the temperature-sensitive magnetic part; a magnet arranged at one end of the electrode facing the atomizer core; wherein, when the temperature-sensitive magnetic part exhibits ferromagnetism, the magnet is magnetically attracted to the temperature-sensitive magnetic part, and the electrode is electrically connected to the atomizer core; when the temperature-sensitive magnetic part exhibits paramagnetism, the magnet fails to magnetically attract the temperature-sensitive magnetic part, and the electrode is electrically disconnected from the atomizer core.

[0005] In some embodiments, the temperature-sensitive magnetic component is electrically connected to the atomizer core, and when the temperature-sensitive magnetic component exhibits ferromagnetism, the electrode is electrically connected to the temperature-sensitive magnetic component.

[0006] In some embodiments, the temperature-sensitive magnetic element has a hollow portion. When the temperature-sensitive magnetic element exhibits ferromagnetism, the electrode passes through the hollow portion and is electrically connected to the atomizer core.

[0007] In some embodiments, the electrode comprises:

[0008] A conductive member, used to be electrically connected to the temperature-sensitive magnetic member or the atomizer core, and the magnet is fixedly connected to one end of the conductive member facing the atomizer core;

[0009] The elastic member is electrically connected to an end of the conductive member away from the temperature-sensitive magnetic member, and elastically supports the conductive member.

[0010] In some embodiments, the electrode further includes a conductive sleeve, the conductive member is located in the conductive sleeve, the elastic member is elastically supported between the bottom wall of the conductive sleeve and the conductive member, and the elastic member is electrically connected to the conductive sleeve.

[0011] In some embodiments, the electrode further includes a conductive sleeve and a conductive collar. The conductive collar is fixedly connected inside the conductive sleeve. The conductive collar is in clearance fit with the conductive member. The elastic member is elastically supported between the conductive collar and the conductive member, and the elastic member is electrically connected to the conductive collar.

[0012] In some embodiments, the conductive sleeve includes a first barrel and a second barrel connected to each other. The inner diameter of the first barrel is smaller than that of the second barrel. The conductive collar is fixedly connected inside the first barrel. When the magnetic attraction between the magnet and the temperature-sensitive magnetic member disappears, the magnet is received inside the second barrel and can be stopped at the end of the first barrel.

[0013] In some embodiments, the electrode further includes a conductive support member. The elastic member is elastically supported between the conductive support member and the conductive member, and the elastic member is electrically connected to the conductive support member. The conductive member is sleeved on the conductive support member.

[0014] In some embodiments, the conductive support member includes a guiding portion and a supporting portion. The supporting portion is connected to one end of the guiding portion away from the conductive member. The conductive member is sleeved on the guiding portion. The elastic member is elastically supported between the supporting portion and the conductive member.

[0015] In some embodiments, the conductive member is a conductive barrel, which includes a barrel wall and a bottom wall. The bottom wall is connected to one end of the barrel wall facing the temperature-sensitive magnetic member. The barrel wall is sleeved on the conductive support member. The elastic member is elastically supported between the bottom wall and the conductive support member.

[0016] In some embodiments, the atomizer further includes a mounting seat and a supporting seat. The mounting seat and the supporting seat are connected and fix the atomization core. The supporting seat has an atomization cavity. The temperature-sensitive magnetic member is located inside the atomization cavity. The supporting seat is provided with an assembly hole, which communicates with the atomization cavity. The electrode is assembled in the assembly hole, and one end of the electrode facing away from the atomization core exposes from the supporting seat.

[0017] To solve the above technical problems, another technical solution adopted by this application is: to provide an electronic atomization device. The electronic atomization device includes a battery assembly and the atomizer as described above. The battery assembly and the atomizer are detachably connected, and the battery assembly supplies power to the atomizer.

[0018] The beneficial effects of the present application are as follows: Different from the prior art, the present application discloses an atomizer and an electronic atomization device. In the embodiments of the present application, a temperature-sensitive magnetic member is fixed on the atomization core, and the electrode is configured to be movably arranged relative to the temperature-sensitive magnetic member. A magnet is arranged at one end of the electrode facing the atomization core. Since the temperature of the temperature-sensitive magnetic member changes following the temperature of the atomization core, when the atomization core undergoes dry burning and the temperature becomes too high to reach the Curie point of the temperature-sensitive magnetic member, the temperature-sensitive magnetic member changes from ferromagnetic to paramagnetic. As a result, the magnetic attraction between the magnet and the temperature-sensitive magnetic member fails, causing the electrode to disconnect the electrical connection with the atomization core. Therefore, it is possible to avoid the occurrence of the atomization core generating a burnt smell and self-damage due to continuous dry burning, that is, the atomizer provided by the present application can perform self-protection to avoid dry burning of the atomization core.

Those skilled in the art understand explicitly and implicitly that the embodiments described herein can be combined with other embodiments.

[0036] This application provides an atomizer 100. Refer to Figures 1 to 3 , Figure 1 It is a schematic structural diagram of an embodiment of the atomizer provided by this application,Figure 2 is Figure 1 a schematic cross-sectional structure diagram of the atomizer in Figure 3 is Figure 2 an enlarged structure diagram of area A in

[0037] The atomizer 100 generally includes an atomization sleeve 10, a mounting base 20, an atomization core 30, a temperature-sensitive magnetic part 40, an electrode 50, a magnet 60, and a support base 70.

[0038] The atomization sleeve 10 has a liquid storage cavity 11 and a ventilation pipe 13. The mounting base 20 has a liquid inlet cavity 21 and an aerosol outlet 23. The mounting base 20 is located in the liquid storage cavity 11, and the mounting base 20 is hermetically assembled with the atomization sleeve 10. The liquid inlet cavity 21 communicates with the liquid storage cavity 11. The atomization core 30 is connected to one end of the mounting base 20 facing away from the liquid storage cavity 11 and blocks the liquid inlet cavity 21. The liquid inlet cavity 21 guides the liquid matrix stored in the liquid storage cavity 11 to the atomization core 30. The atomization core 30 is used to atomize the liquid matrix to form an aerosol for the user to inhale. The ventilation pipe 13 is connected to the aerosol outlet 23.

[0039] The support base 70 covers one end of the atomization sleeve 10 with an opening, and the mounting base 20 and the support base 70 are connected and fix the atomization core 30. The support base 70 has an atomization cavity 71. The atomization cavity 71 communicates with the aerosol outlet 23. One end of the atomization core 30 facing away from the liquid storage cavity 11 also extends into the atomization cavity 71, and the atomization core 30 forms an aerosol in the atomization cavity 71. The aerosol sequentially passes through the aerosol outlet 23 and the ventilation pipe 13 from the atomization cavity 71 and enters the human oral cavity.

[0040] The temperature-sensitive magnetic part 40 is fixedly connected to one end of the atomization core 30 facing away from the liquid storage cavity 11, and the temperature-sensitive magnetic part 40 is located in the atomization cavity 71. The support base 70 is provided with an assembly hole 63, and the assembly hole 63 communicates with the atomization cavity 71. The electrode 50 is assembled in the assembly hole 63. One end of the electrode 50 facing away from the atomization core 30 exposes from the support base 70 for connecting an external battery assembly; one end of the electrode 50 facing the atomization core 30 can be electrically connected to the atomization core 30 to conduct the power of the battery assembly to the atomization core 30.

[0041] The temperature-sensitive magnetic part 40 is fixed on the atomization core 30, and the temperature of the temperature-sensitive magnetic part 40 rises as the temperature of the atomization core 30 rises. It should be noted that the temperature-sensitive magnetic part 40 has a high thermal conductivity and can quickly follow the temperature change of the atomization core 30.

[0042] The temperature-sensitive magnetic part 40 can be welded to the atomization core 30, or the temperature-sensitive magnetic part 40 and the atomization core 30 are co-fired into an integral structure. The present application does not limit the way of fixing the temperature-sensitive magnetic part 40 on the atomization core 30.

[0043] The material used for the temperature-sensitive magnetic component 40 is a soft magnetic material. Magnetic materials are classified into soft magnetic materials and hard magnetic materials according to whether there is still magnetism (the magnitude of the residual magnetism) in the magnetic material after the external magnetic field that magnetizes the material is removed. After the external magnetic field is removed, hard magnetic materials have a relatively large residual magnetism and retain their magnetism, and are also called permanent magnets; soft magnetic materials are a type of material with less residual magnetism after the external magnetic field disappears, and their magnetism disappears, showing paramagnetism.

[0044] Among them, the above magnetization processes all occur below the Curie point of the material. The Curie point, also known as the Curie temperature or magnetic transition point, refers to the temperature at which the spontaneous magnetization intensity in the magnetic material drops to zero. When the temperature is below the Curie point, the material can be magnetized and shows ferromagnetic or ferrimagnetic properties; when the temperature is higher than the Curie point, the magnetic material cannot be magnetized and shows paramagnetic properties.

[0045] Figure 4 is the temperature characteristic curve of the soft magnetic material. From Figure 4 it can be seen that when the temperature of the soft magnetic material reaches a certain critical value, its magnetic permeability changes suddenly and decays rapidly, and its magnetic permeability almost decays to 0, and this critical value is the Curie point.

[0046] Therefore, under the action of an external magnetic field, when the temperature of the temperature-sensitive magnetic component 40 is lower than its own Curie point, the temperature-sensitive magnetic component 40 shows ferromagnetic properties; when the temperature of the temperature-sensitive magnetic component 40 is higher than the Curie point, the temperature-sensitive magnetic component 40 changes from ferromagnetic to paramagnetic. When the temperature-sensitive magnetic component 40 shows ferromagnetic properties, the temperature-sensitive magnetic component 40 can be attracted by a magnet; when the temperature-sensitive magnetic component 40 shows paramagnetic properties, the temperature-sensitive magnetic component 40 cannot be attracted by a magnet.

[0047] The electrode 50 is installed on the support base 70, and the electrode 50 is movably arranged relative to the temperature-sensitive magnetic component 40. The magnet 60 is arranged at one end of the electrode 50 facing the atomization core 30.

[0048] Among them, when the temperature-sensitive magnetic component 40 shows ferromagnetic properties, the magnet 60 is magnetically attracted to the temperature-sensitive magnetic component 40, and the electrode 50 is electrically connected to the atomization core 30; when the temperature-sensitive magnetic component 40 shows paramagnetic properties, the magnetic attraction between the magnet 60 and the temperature-sensitive magnetic component 40 fails. In other words, the electrode 50 and the temperature-sensitive magnetic component 40 are separated due to the loss of magnetic attraction, and the electrode 50 is disconnected from the atomization core 30.

[0049] Among them, the number of the temperature-sensitive magnetic components 40 and the electrodes 50 is two, and the two electrodes 50 are respectively configured as the positive and negative electrodes of the atomizer 100.

[0050] Under normal circumstances, a large amount of liquid matrix is ​​stored in the liquid storage chamber 11. When the atomizer core 30 is working, the temperature of the atomizer core 30 itself is maintained in a normal operating temperature range, for example, the operating temperature range is 200°C to 250°C, preferably 200°C to 220°C, and the atomizer core 30 will not produce a burnt smell or dry burn due to insufficient supply of liquid matrix when atomizing the liquid matrix. When the liquid matrix in the liquid storage chamber 11 is about to run out, the atomizer core 30 is prone to dry burn due to too little liquid matrix, and as the atomizer core 30 is dry burned, the temperature of the atomizer core 30 rises rapidly, and the atomizer core 30 will produce a burnt smell, affecting the user's taste. At the same time, its own temperature is too high and it is easy to self-damage.

[0051] In the presence of an external magnetic field, the temperature-sensitive magnetic component 40 switches between ferromagnetism and paramagnetism as its own temperature changes. Therefore, when the temperature of the atomizer core 30 is too high, the temperature of the temperature-sensitive magnetic component 40 is higher than the Curie point of its own material, and the temperature-sensitive magnetic component 40 changes from ferromagnetism to paramagnetism. The electrode 50 loses its magnetic attraction with the temperature-sensitive magnetic component 40 and separates, and the electrode 50 is electrically disconnected from the atomizer core 30. Then the atomizer core 30 stops working to avoid burning smell and self-damage.

[0052] Optionally, the temperature-sensitive magnetic component 40 can be made of ferromagnetic materials such as PC40 and PC44, and the Curie point of the material is close to the temperature at which the atomizer core 30 is dry-burned and produces a burnt smell.

[0053] For example, the material used for the temperature-sensitive magnetic component 40 is PC44. Figure 5 As shown, the Curie point of PC44 is 215°C. When the temperature reaches 215°C, the magnetic permeability of PC44 changes suddenly, dropping from the highest point to zero. PC44 changes from ferromagnetism to paramagnetism and is no longer attracted by magnets.

[0054] Alternatively, the material used for the temperature-sensitive magnetic component 40 is PC40. Figure 6 As shown, the Curie point of PC40 is in the range of 225°C to 230°C. When the temperature reaches the Curie point, the magnetic permeability of PC40 changes suddenly from the highest point to zero, and PC40 changes from ferromagnetism to paramagnetism and is no longer attracted by the magnet. Alternatively, the material used for the temperature-sensitive magnetic part 40 is PC95. Figure 7 As shown, the Curie point of PC95 is 240℃. When the temperature reaches the Curie point, the magnetic permeability of PC95 changes suddenly, dropping from the highest point to zero. PC95 changes from ferromagnetism to paramagnetism and is no longer attracted by magnets.

[0055] In the embodiment of the present application, the temperature-sensitive magnetic component 40 is fixed on the atomizer core 30, and the electrode 50 is configured to be movable relative to the temperature-sensitive magnetic component 40, and the magnet 60 is arranged at one end of the electrode 50 facing the atomizer core 30. Since the temperature of the temperature-sensitive magnetic component 40 changes with the temperature of the atomizer core 30, when the atomizer core 30 is dry-burned and the temperature is too high to reach the Curie point of the temperature-sensitive magnetic component 40, the temperature-sensitive magnetic component 40 changes from ferromagnetism to paramagnetism, so that the magnetic attraction between the magnet 60 and the temperature-sensitive magnetic component 40 fails, so that the electrode 50 and the atomizer core 30 are electrically disconnected, thereby preventing the atomizer core 30 from generating a burnt smell and self-damage due to continued dry burning, that is, the atomizer 100 provided by the present application can perform self-protection and prevent the atomizer core 30 from dry burning.

[0056] In this embodiment, Figure 3 As shown, the electrode 50 is indirectly electrically connected to the atomizer core 30, and the electrode 50 is electrically connected to the atomizer core 30 through the temperature-sensitive magnetic component 40. The temperature-sensitive magnetic component 40 is in a block shape, and the temperature-sensitive magnetic component 40 is fixed on the atomizer core 30 and is also electrically connected to the atomizer core 30. Therefore, when the temperature-sensitive magnetic component 40 exhibits ferromagnetism, the electrode 50 contacts and electrically connects with the temperature-sensitive magnetic component 40, and when the temperature-sensitive magnetic component 40 exhibits paramagnetism, the electrode 50 separates from the temperature-sensitive magnetic component 40 and disconnects the electrical connection.

[0057] In other embodiments, the electrode 50 is directly electrically connected to the atomizer core 30. Figure 8 As shown, the temperature-sensitive magnetic element 40 has a hollow portion 41 . When the temperature-sensitive magnetic element 40 exhibits ferromagnetism, the magnet 60 is magnetically attracted to the temperature-sensitive magnetic element 40 , and the electrode 50 passes through the hollow portion 41 and is electrically connected to the atomizer core 30 .

[0058] The hollow portion 41 may be a through hole or a through groove, and when the electrode 50 and the temperature-sensitive magnetic component 40 are magnetically attracted to each other, the electrode 50 is directly electrically connected to the atomizer core 30 through the hollow portion 41 .

[0059] See also Figure 3 The electrode 50 includes a conductive member 51 and an elastic member 53. The conductive member 51 is used to be electrically connected to the temperature-sensitive magnetic member 40 or the atomizer core 30. The magnet 60 is fixedly connected to one end of the conductive member 51 facing the temperature-sensitive magnetic member 40. The elastic member 53 is connected to one end of the conductive member 51 facing away from the temperature-sensitive magnetic member 40, and elastically supports the conductive member 51 so that the conductive member 51 is relatively suspended. The elastic force of the elastic member 53 at least offsets part of the self-weight of the conductive member 51, so that the magnet 60 can easily drive the conductive member 51 to move when the temperature-sensitive magnetic member 40 is magnetically attracted, and the conductive member 51 is in contact with the temperature-sensitive magnetic member 40 or the atomizer core 30 and is electrically connected.

[0060] Specifically, when there is no magnetic attraction between the magnet 60 and the temperature-sensitive magnetic part 40, the elastic force of the elastic part 53 offsets the self-weight of the conductive part 51, so that the conductive part 51 is suspended in the air; therefore, when there is magnetic attraction between the magnet 60 and the temperature-sensitive magnetic part 40, the magnet 60 drives the conductive part 51 to move toward the atomizer core 30 until the conductive part 51 contacts and is electrically connected to the temperature-sensitive magnetic part 40 or the atomizer core 30. At this time, the elastic force of the elastic part 53 decreases, and the elastic force of the elastic part 53 offsets part of the self-weight of the conductive part 51, so that the magnet 60 drives the conductive part 51 to move toward the atomizer core 30 only by overcoming part of the self-weight of the conductive part 51. Therefore, the conductive part 51 is more sensitive to contact with the temperature-sensitive magnetic part 40 or the atomizer core 30, that is, the sensitivity of the electrical connection between the electrode 50 and the temperature-sensitive magnetic part 40 or the atomizer core 30 is improved.

[0061] In this embodiment, the magnet 60 is disposed around the peripheral wall of the conductive member 51 .

[0062] In other embodiments, Figure 9 As shown, a groove 510 is provided on the end surface of the conductive member 51 facing the temperature-sensitive magnetic member 40 , and the magnet 60 is embedded in the groove 510 .

[0063] It should be noted that when the conductive component 51 is in contact with the temperature-sensitive magnetic component 40 or the atomizer core 30 and is electrically connected, there is a gap between the magnet 60 and the temperature-sensitive magnetic component 40 to prevent the conductive component 51 from being unable to contact with the temperature-sensitive magnetic component 40 or the atomizer core 30 due to the magnetic attraction contact between the magnet 60 and the temperature-sensitive magnetic component 40, resulting in the conductive component 51 being unable to be electrically connected with the temperature-sensitive magnetic component 40 or the atomizer core 30.

[0064] The magnet 60 may be a permanent magnet or an electromagnet, which is not limited in the present application.

[0065] The elastic member 53 may be a spring or an elastic sleeve, etc. It only needs to be able to elastically support the conductive member 51 , and the present application does not impose any limitation on this.

[0066] In some embodiments, Figure 10 As shown, the electrode 50 also includes a conductive sleeve 54, and the conductive member 51 is located in the conductive sleeve 54, and the conductive sleeve 54 can also guide the conductive member 51 so that the conductive member 51 moves axially relative to the conductive sleeve 54 to ensure that the conductive member 51 is in alignment with the temperature-sensitive magnetic member 40 or the atomization core 30.

[0067] The elastic member 53 is elastically supported between the bottom wall of the conductive sleeve 54 and the conductive member 51. The compressive elastic force of the elastic member 53 makes the conductive member 51 suspended relative to the bottom wall of the conductive sleeve 54. The elastic member 53 is electrically connected to the conductive sleeve 54. One end of the conductive sleeve 54 away from the atomizer core 30 is exposed from the support seat 70 for connecting to an external battery assembly.

[0068] In this embodiment,Figure 3 As shown, the electrode 50 further includes a conductive sleeve 54 and a conductive collar 55. The conductive collar 55 is fixedly connected inside the conductive sleeve 54. The conductive collar 55 has a clearance fit with the conductive member 51. The conductive member 51 can move axially relative to the conductive collar 55 along the conductive sleeve 54, and the conductive collar 55 has a guiding effect on the conductive member 51.

[0069] The elastic member 53 is elastically supported between the conductive collar 55 and the conductive member 51. Then, the tensile elastic force of the elastic member 53 causes the conductive member 51 to be suspended relative to the bottom wall of the conductive sleeve 54. The elastic member 53 is electrically connected to the conductive collar 55, the conductive collar 55 is electrically connected to the conductive sleeve 54, and one end of the conductive sleeve 54 facing away from the atomization core 30 exposes from the support base 70 for connecting an external battery assembly.

[0070] Further, with reference to Figure 3 and Figure 6 , the conductive sleeve 54 is a stepped cylinder. The conductive sleeve 54 includes a first cylinder 541 and a second cylinder 543 that are connected to each other. The inner diameter of the first cylinder 541 is smaller than that of the second cylinder 543. The conductive collar 55 is fixedly connected inside the first cylinder 541. When the magnetic attraction between the magnet 60 and the temperature-sensitive magnetic member 40 disappears, the magnet 60 is collected inside the second cylinder 543 and can be stopped at the end of the first cylinder 541.

[0071] The conductive sleeve 54 is embedded in the assembly hole 63. The second cylinder 543 is located inside the atomization cavity 71, and the outer stepped surface formed between the first cylinder 541 and the second cylinder 543 abuts against the bottom surface of the support base 70 to reduce the risk of the conductive sleeve 54 slipping out of the assembly hole 63. Also, the second cylinder 543 located inside the atomization cavity 71 can block the leakage of liquid from entering the conductive sleeve 54 and damaging the electrode 50.

[0072] In some other embodiments, as Figure 11 shown, the electrode 50 further includes a conductive support member 56. The elastic member 53 is elastically supported between the conductive support member 56 and the conductive member 51. The elastic member 53 is electrically connected to the conductive support member 56, and the conductive member 53 is sleeved on the conductive support member 56.

[0073] The conductive member 51 is a conductive cylinder. The conductive support member 56 includes a guiding portion 561 and a supporting portion 563. The supporting portion 563 is connected to one end of the guiding portion 561 away from the conductive member 51. The conductive member 51 is sleeved on the guiding portion 561. The elastic member 53 is elastically supported between the supporting portion 563 and the conductive member 51, and the elastic member 53 is electrically connected to the supporting portion 563.

[0074] The guide portion 561 may be a guide shaft, and the support portion 563 may be a disc. The conductive member 51 is sleeved on the guide portion 561 to ensure that the conductive member 51 is electrically connected to the temperature-sensitive magnetic member 40 or the atomizer core 30. The support portion 563 is embedded in the assembly hole 63, and the side of the support portion 563 facing away from the atomizer core 30 is exposed from the support seat 70 for electrically connecting to the battery assembly.

[0075] In other embodiments, Figure 12 As shown, the conductive member 51 is a conductive cylinder, which includes a cylinder wall 511 and a bottom wall 513. The bottom wall 513 is connected to one end of the cylinder wall 511 facing the temperature-sensitive magnetic member 40. The cylinder wall 511 is sleeved with the conductive support member 56, and the elastic member 53 is elastically supported between the bottom wall 513 and the conductive support member 56.

[0076] For example, the conductive support member 56 is columnar, and the elastic member 53 is elastically supported between the bottom wall 513 and the end of the conductive support member 56 facing the bottom wall 513. Alternatively, the conductive support member 56 is cylindrical, the elastic member 53 is partially located inside the conductive support member 56, and the elastic member 53 is elastically supported between the bottom wall 513 and the bottom wall of the conductive support member 56.

[0077] See also Figure 13 Based on this, the present application also provides an electronic atomization device 200, which includes a battery assembly 203 and the atomizer 100 as described above, the battery assembly 203 and the atomizer 100 are connected, and the battery assembly 203 supplies power to the atomizer 100.

[0078] Different from the prior art, the present application discloses an atomizer and an electronic atomization device. The embodiment of the present application fixes a temperature-sensitive magnetic part on the atomizer core, and configures an electrode to be movably arranged relative to the temperature-sensitive magnetic part, and sets a magnet at one end of the electrode facing the atomizer core. Since the temperature of the temperature-sensitive magnetic part changes with the temperature of the atomizer core, when the atomizer core is dry-burned and the temperature is too high and reaches the Curie point of the temperature-sensitive magnetic part, the temperature-sensitive magnetic part changes from ferromagnetism to paramagnetism, so that the magnetic attraction between the magnet and the temperature-sensitive magnetic part fails, so that the electrode and the atomizer core are electrically disconnected, thereby preventing the atomizer core from producing a burnt smell and self-damage due to continued dry burning, that is, the atomizer provided by the present application can protect itself and prevent the atomizer core from dry burning.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
