The first magnetic connector  134  and the first electrode connector  135  are disposed at one end of the mounting base  133  of the atomizer  13  facing the power supply assembly  14 . Specifically, the end of the mounting base  133  facing the power supply assembly  14  defines a third recess  1331  and a fourth recess  1332  spaced apart from each other.

     The power supply assembly  14  includes a second magnetic connector  141  and a second electrode connector  142 . The second magnetic connector  141  and the second electrode connector  142  are disposed at one end of the power supply assembly  14  facing the atomizer  13 . Specifically, the end of the power supply assembly  14  facing the atomizer  13  defines a fifth recess  143  and a sixth recess  144  spaced apart from each other. The second magnetic connector  141  is disposed in the fifth recess  143 , and the second electrode connector  142  is disposed in the sixth recess  144 . In one embodiment, the number of each of the second magnetic connector  141 , the second electrode connector  142 , the fifth recess  143 , and the sixth recess  144  is two. In other embodiments, the number of each of the number of the second magnetic connector  141 , the second electrode connector  142 , the fifth recess  143 , and the sixth recess  144  can be more than two.

The fourth recess  1332  is disposed opposite to the sixth recess  144 , so that the first electrode connector  135  can be electrically connected with the second electrode connector  142 . The power supply assembly  14  and the atomizer  13  can be fixed by magnetic attraction between the first magnetic connector  134  and the second magnetic connector  141 . Furthermore, the first electrode connector  135  and the second electrode connector  142  are in contact with each other and electrically connected, so that the power supply assembly  14  can supply power to the atomizer  13  and the atomizer  13  can be powered to work. 
     The material of one of the first magnetic connector  134  and the second magnetic connector  141  is a temperature sensitive magnetic material, and the material of the other one of the first magnetic connector  134  and the second magnetic connector  141  is a magnetic material or iron. In one embodiment, the material of the first magnetic connector  134  is a magnet and the material of the second magnetic connector  141  is iron. In one embodiment, the distance between the first magnetic connector  134  and the atomization core  132  is very short, and the heat released by the atomization core  132  can be soon transmitted to the first magnetic connector  134 , thus the first magnetic connector  134  can sense the temperature of the atomization core  132  easily. In one embodiment, the magnetic material can be a temperature sensitive magnet, for example the magnet can be a samarium cobalt (SmCo) magnet, a neodymium iron boron (NdFeB) magnet, or an aluminum nickel cobalt (AlNiCo) magnet. In other embodiments, the material of the first magnetic connector  134  may be iron and the material of the second magnetic connector  141  may be magnet. Alternatively, the material of both the first magnetic connector  134  and the second magnetic connector  141  is magnet. Also, the heat of the atomization core  132  can be transmitted to the first magnetic connector  134  and the second magnetic connector  141  by heat conduction. 
     In other embodiments, the end of the mounting base  133  close to the power supply assembly  14  can also be provided with an end cover, the end cover can be used as the first magnetic connector  134 , namely, the end cover can be used as the first magnetic connector  134  and magnetically attracted with the second magnetic connector  141 . The material of the end cover can be magnetic material or iron, and the magnetic material can be magnet, for example the magnet can be a SmCo magnet, a NdFeB magnet, or an AlNiCo magnet. Since the mounting base  133  is used as the first magnetic connector  134 , the structure of the atomizer  13  can be simplified, and further the structure of the electronic atomization device  10  is simplified. 
     One of the first electrode connector  135  and the second electrode connector  142  may be a thimble, and the other one of the first electrode connector  135  and the second electrode connector  142  may be an electrode. The power supply assembly  14  and the atomizer  13  can be electrically connected by contact between the thimble and the electrode. In other embodiments, the first electrode connector  135  and the second electrode connector  142  are not limited to the above elements, and can also be other elements, as long as the electrical connection between the power supply assembly  14  and the atomizer  13  can be realized. 
     In one embodiment, the electronic atomization device  10  also includes an elastic element  15 , and the elastic element  15  is disposed between the atomizer  13  and the power supply assembly  14 . Specifically, one end of the power supply assembly  14  close to the atomizer  13  of the embodiment defines a first recess  145 . One end of the elastic element  15  is disposed in the first recess  145  and can be fixed in the first recess  145 , and the other end of the elastic element  15  is in contact with or connected to the atomizer  13 . The elastic element  15  in the first recess  145  can stretch along the axial direction of the elastic element  15 . 
     The elastic element  15  may be a coil spring or a flat spring, or other elastic structure. In the embodiment, the elastic element  15  is described by taking a coil spring as an example. 
     Generally, the increase of temperature will weaken the magnetism of the magnet, thus the magnetic attraction between the atomizer  13  and the power supply assembly  14  may be weakened. When the working temperature of the atomizer  13  is higher than or equal to a threshold temperature, the temperature is transmitted to the magnet, which may cause the attraction force between the first magnetic connector  134  and the second magnetic connector  141  be weaken or. The threshold temperature can be set as the Curie temperature of the magnet, when the temperature of the magnet is above the Curie temperature of the magnet, the magnet will not be magnetic. Namely, the attraction force between the first magnetic connector  134  and the second magnetic connector  141  will disappear. The Curie temperatures of common magnets are as follows: 60° C.˜200° C. for NdFeB magnets, 250° C.˜350° C. for SmCo magnets and 450° C.˜900° C. for AlNiCo magnets. Different liquid requires different atomization temperature, so different magnets can be selected according to the different liquid substance. 
     Referring to  FIGS. 4 and 5 ,  FIG. 5  is a structural schematic view of  FIG. 4  when the working temperature of the atomizer is higher than or equal to the threshold temperature. 
     Referring to  FIG. 4 , when the working temperature of the atomizer  13  is lower than the threshold temperature, the first magnetic connector  134  and the second magnetic connector  141  have a greater magnetism and a stronger attraction force. When the attraction force between the first magnetic connector  134  and the second magnetic connector  141  is greater than or equal to the elastic force of the coil spring, the first magnetic connector  134  and the second magnetic connector  141  are magnetically attracted, namely, the power supply assembly  14  and the atomizer  13  are magnetically attracted, and the coil spring is compressed, so that the coil spring has an elastic potential energy. 
     Referring to  FIG. 5 , in one embodiment, when the material of the first magnetic connector  134  is a magnet and the material of the second magnetic connector  141  is iron. When the working temperature of the atomizer  13  is higher than or equal to the threshold temperature, heat of the atomizer  13  is transmitted to the first magnetic connector  134 , and the temperature of the first magnetic connector  134  and the second magnetic connector  141  can be increased, the magnetism of the first magnetic connector  134  is weakened and the attraction force is weakened. When the temperature of the first magnetic connector  134  reaches the Curie temperature, the first magnetic connector  134  will lost magnetism, and the attraction force between the first magnetic connector  134  and the second magnetic connector  141  disappears. When the attraction force between the first magnetic connector  134  and the second magnetic connector  141  is less than the elastic force of the coil spring, the coil spring releases the elastic potential energy to push the atomizer  13  away from the power supply assembly  14 , so that the first magnetic connector  134  is separated from the second magnetic connector  141 . Thus, the atomizer  13  and the power supply assembly  14  are electrically disconnected from each other. 
     Alternatively, when the working temperature of the atomizer  13  is lower than or equal to the threshold temperature, the first magnetic connector  134  and the second magnetic connector  141  have a greater magnetism and a stronger attraction force. When the attraction force between the first magnetic connector  134  and the second magnetic connector  141  is greater than or equal to the elastic force of the coil spring, the first magnetic connector  134  and the second magnetic connector  141  are magnetically attracted, namely, the power supply assembly  14  and the atomizer  13  are magnetically attracted, and the coil spring is compressed, so that the coil spring has an elastic potential energy. When the working temperature of the atomizer  13  is higher than the threshold temperature, heat of the atomizer  13  is transmitted to the first magnetic connector  134 , so that the temperatures of the first magnetic connector  134  and the second magnetic connector  141  are increased, and the magnetism and attraction force between the first magnetic connector  134  are decreased. When the temperature of the first magnetic connector  134  reaches the Curie temperature, the first magnetic connector  134  will lost magnetism, and the attraction force between the first magnetic connector  134  and the second magnetic connector  141  disappears. When the attraction force between the first magnetic connector  134  and the second magnetic connector  141  is less than the elastic force of the coil spring, the coil spring releases the elastic potential energy to push the atomizer  13  away from the power supply assembly  14 , so that the first magnetic connector  134  is separated from the second magnetic connector  141 . Thus, the atomizer  13  and the power supply assembly  14  are electrically disconnected from each other. 
     According to the working temperature of the atomizer  13  and the threshold temperature, the first magnetic connector  134  and the second magnetic connector  141  make the power supply assembly  14  and the atomizer  13  being electrically connected, or, the elastic element  15  make the atomizer  13  and the power supply assembly  14  being electrically disconnected from each other. 
     In other embodiments, for example, the material of the first magnetic connector  134  is iron and the material of the second magnetic connector  141  is magnet. When the working temperature of the atomizer  13  is higher than or equal to the threshold temperature, the heat of the atomizer  13  is transmitted to the first magnetic connector  134 , the temperature of the first magnetic connector  134  is increased and the heat of the first magnetic connector  134  is transmitted to the second magnetic connector  141 . When the temperature of the second magnetic connector  141  is increased, the magnetism of the second magnetic connector  141  is decreased, and the attraction force between the second magnetic connector  141  is decreased. When the temperature of the first magnetic connector  134  reaches the Curie temperature, the second magnetic connector  141  will lost magnetism, and the attraction force between the first magnetic connector  134  and the second magnetic connector  141  disappears. When the attraction force between the first magnetic connector  134  and the second magnetic connector  141  is less than the elastic force of the coil spring, the coil spring releases the elastic potential energy to push the atomizer  13  away from the power supply assembly  14 , so that the first magnetic connector  134  is separated from the second magnetic connector  141 . Thus, the atomizer  13  and the power supply assembly  14  are electrically disconnected from each other. 
     In other embodiments, for example, the material of both the first magnetic connector  134  and the second magnetic connector  141  is magnet. When the working temperature of the atomizer  13  is higher than or equal to the above threshold temperature, the heat of the atomizer  13  is transmitted to the first magnetic connector  134 , the temperature of both the first magnetic connector  134  and the second magnetic connector  141  is increased, the temperature of the first magnetic connector  134  and the second magnetic connector  141  are increased, the magnetism of both the first magnetic connector  134  and the second magnetic connector  141  are decreased, and the attraction force between the first magnetic connector  134  and the second magnetic connector  141  are decreased. When the temperature of the first magnetic connector  134  reaches the Curie temperature, the first magnetic connector  134  and the second magnetic connector  141  will lost magnetism, and the attraction force between the first magnetic connector  134  and the second magnetic connector  141  disappears. When the attraction force between the first magnetic connector  134  and the second magnetic connector  141  is less than the elastic force of the coil spring, the coil spring releases the elastic potential energy to push the atomizer  13  away from the power supply assembly  14 , so that the first magnetic connector  134  is separated from the second magnetic connector  141 . Thus, the atomizer  13  and the power supply assembly  14  are electrically disconnected from each other. 
     The electronic atomization device has an elastic element  15  compare to prior art. When the temperature of the atomizer  13  is too high due to the atomizer  13  is heated in dry state, charging or other conditions, the elastic element  15  can make the atomizer  13  and the power supply assembly  14  being electrically disconnected from each other, so that the atomizer  13  stop working, thus, the atomizer  13  is prevented from being heated in dry state or abnormal work, and the user&#39;s use experience is improved. 
     When the temperature of the magnet increases, the attraction force of the magnet will decrease, but most of the attraction force will recover after the magnet is cooled. Therefore, when the temperature of the atomizer  13  is too high, the power will be cut off, and after the first magnetic connector  134  and the second magnetic connector  141  being cool down slowly, the attraction force between the first magnetic connector  134  and the second magnetic connector  141  will recover, and the coil spring will be compressed, so that the atomizer  13  and the power supply assembly  14  are electrically connected with each other, and the atomizer  13  can work normally again. 
     In other embodiments, one end of the atomizer  13  close to the power supply assembly  14  defines a second recess, one end of the elastic element  15  is disposed in the second recess and can be fixed in the second recess, the other end of the elastic element  15  is in contact with or connected to the power supply assembly  14 , and the elastic element  15  can stretch along the axial direction in the second recess. The second recess may be a recess disposed at the bottom of the mounting base  133  of the atomizer  13 . In one embodiment, the second recess is an air inlet at the bottom of the mounting base  133  of the atomizer  13 , thus the structure of the atomizer  13  is simplified. 
     In other embodiments, the first magnetic connector  134  extends from an end face of the mounting base  133  of the atomizer  13  close to the power supply assembly  14  to a place near the atomization core  132  of the atomizer  13 . Specifically, the mounting base  133  of the atomizer  13  includes a base and a fixing part, the fixing part is located on the side of the base away from the power supply assembly  14 . The end face of the mounting base  133  close to the power supply assembly  14  defines a third recess  1331 , and the third recess  1331  is disposed on the bottom. The third recess  1331  can cross through the base and extends to the fixing part, and the first magnetic connector  134  is disposed in the third recess  1331 . When the third recess  1331  cross through the bottom and extends to the fixing part, the first magnetic connector  134  can be closer to the atomization core  132 . Since the first magnetic connector  134  is close to the atomization core  132 , the heat conduction between the atomization core  132  and the first magnetic connector  134  is faster, thus the first magnetic connector  134  can sense the temperature of the atomization core  132  easily.
