[0041] Referring to FIG. 2-FIG. 7, an atomization assembly 1 according to an embodiment of the invention comprises a cover 13, a base 14, a heating assembly 11 and an electrode 16. A compartment 15, which matches the heating assembly 11 in size and shape, is disposed on one of the cover 13 and the base 14 and is open towards the other one of the cover 13 and the base 14, and preferably, the compartment is disposed on the cover. The heating assembly 11 is disposed in the compartment 15, the cover 13 is assembled with the base 14, and heating assembly 11 is sandwiched between the cover 13 and the base 14. The heating assembly 11 comprises a support 112 and a heating element 111. The heating element 111 comprises a main part 1111 and an electrical connection part 1112 connected to the main part 1111. The main part 1111 comprises a heating circuit 11111 used for generating heat to heat and atomize liquid, and the heating element 111 transversely contacts with the top of the support 112, such that the heating element 111 is supported by the support 112. The electrical connection part 1112 is bent from the top of the support 112 to one side of the support 112, or the electrical connection part 112 is bent from the top of the support 112 to one side of the support 112 and is then bent to the bottom of the support 112, or the electrical connection part 1112 is bent from the top of the support 112 to one side of the support 112 and is then engaged in the support 112.

[0042] The electrode 16 comprises a first part 161, a second part 162 and a third part 163 which are connected to each other. The first part 161 is located on a transverse side of the electrical connection part 1112, the side face of the first part 161 is at least in contact with the portion, bent to one side of the support 112, of the electrical connection part 1112 to realize electrical connection. The second part 162 is connected to the base. The third part 163 is exposed out of the base 14 to be in contact with an external circuit to realize electrical connection.

[0043] According to the atomization assembly 1, the heating element 111 is supported by the support 112, such that the strength of the heating element 111 is improved; and the electrode 16 can be electrically connected to the electrical connection part 1112 of the heating element 111 easily and reliably.

[0044] Referring to FIG. 6-FIG. 7, in some embodiments, the electrical connection part 1112 may be bent from the top of the support 112 to one side of the support 112. Referring to FIG. 8-FIG. 9, in some other embodiments, the electrical connection part 1112 may be bent from the top of the support 112 to one side of the support 112 and then bent to the bottom of the support 112, such that the support can be better wrapped, and poor contact caused by deformation due to deviation of the electrical connection part 1112 of the heating element 111 when the electrode is inserted is avoided.

[0045] Referring to FIG. 12-FIG. 13, in some embodiments, the electrical connection part 1112 is bent from the top of the support 112 to one side of the support 112 and is then engaged into the support 112. The support 112 is preferably made of plastic, and the heating element 111 and the support 112 may be fixed together through injection molding in a mold, such that the structure is firmer.

[0046] Referring to FIG. 12-FIG. 13, in some embodiments, an electrode hole 141 is formed in the base 14, the second part 162 of the electrode 16 is matched with the electrode hole 141 to connect the electrode 16 to the base 14. The top (M in FIG. 12 and FIG. 13) of the electrode hole 141 is higher than the inner bottom surface of the base 14, such that liquid in the atomization assembly 1 is prevented from leaking from a gap of the electrode hole 141.

[0047] Referring to FIG. 2-FIG. 5, in some embodiments, the first part 161 and the second part 162 of the electrode 16 are rod-shaped, the radial size of the third part 163 is greater than that of the first part 161 and the second part 162. An electrode hole 141 which longitudinally penetrates through the base 14 is formed in the base 14. After the first part 161 and the second part 162 longitudinally penetrate through the electrode hole 141, the second part 162 is connected to the base 14, and the side face of the first part 161 is in contact with the portion, bent to one side of the support 112, of the electrical connection part 1112.

[0048] Two electrical connection parts 1112 are disposed at two ends of the main part 1111 respectively, the atomization assembly 1 comprises two electrodes 16, side walls of the first parts 161 of the two electrodes 16 are in contact with the two electrical connection part 1112 respectively, and the heating assembly 11 is sandwiched between the two electrodes 16.

[0049] Preferably, an electrode connection hole 131 which allows the electrode 16 to be inserted therein and corresponds to the electrode hole 141 is longitudinally formed in the cover 13. The electrode connection hole 131 is open towards the electrode hole 141, and the electrode 16 penetrates through the electrode hole 141 and is inserted into the electrode connection hole 131. When the atomization assembly 1 is assembled, the cover 13, the heating assembly 11 and the base 14 are assembled first, and then the electrode 16 is inserted into the electrode hole 141, such that the electrode 16 and the heating element 111 are electrically connected.

[0050] The compartment 15 and the electrode connection hole 131 are located on the same side of the cover 13.

[0051] The first part 161 of the electrode 16 may be electrically connected to a charger of the atomization assembly 1 to be charged.

[0052] In some embodiments, as shown in FIG. 10-FIG. 11, the electrode 16 has a shape of an elastic plate. The second part 162 of the electrode 16 is integrated with the base 14. The first part 161 of the electrode 16 is disposed on one side of the heating assembly 11, is bent to one side of the support 112 or bent to one side and the bottom of the support 112, and is in elastic contact with the electrical connection part 1112. The exposed third part 163 of the electrode 16 may be electrically connected to the charger of the atomization assembly 1 to be charged.

[0053] The first part 161 is connected to an upper end of the second part 162 and is bent downwards to form an arched part 164 which arches upwards, and the first part 161 is bent downward to be in contact with the portion, bent to one side of the support 112, of the electrical connection part 1112 and is then bent to the bottom of the support 112 to be in contact with the portion, bent to the bottom of the support 112, of the electrical connection part 1112.

[0054] The cover 13 is slightly in interference fit with the first part 161 of the elastic plate-shaped electrode 16, and the cover 13 presses the side, opposite to the electrical connection part 1112, of the electrode 16, such that the first part 161 elastically presses against the electrical connection part 1112. Due to the first part 161 further presses against the electrical connection part 1112, the contact resistance is smaller, and contact is more stable.

[0055] The elastic plate-shaped electrode may be engaged with the base through being bent after being inserted into the base or through injection moulding in a mould. The elastic plate-shaped electrode may be formed by stamping, so the electrode is low in cost and elastic, and can be in good contact with the electrical connection part 1112 of the heating element 111, and the requirement for the size of parts is low. To ensure good contact and small contact resistance, the electrode 16 and the electrical connection part 1112 of the heating element 111 may be electroplated such that protective films are formed on the surface of the electrode 16 and/or on the surface of the electrical connection part 1112 of the heating element 111 through electroplating. According to use requirements, the protective film may be formed through electroplating such as gold plating, nickel plating or chromium plating, to prevent the contact position of the electrode 16 and the electrical connection part 1112 from oxidization so as to avoid contact resistance being increased. In FIG. 11, the position Q is the position where the cover 13 presses of the electrical connection part 1112.

The main part 1111 of the heating element 111 is attached to and contact with the transverse wall 1121 transversely, and the electrical connection parts 1112 are bent from the transverse wall 1121 to the side faces of the longitudinal wall 1122. An air vent 1124 transversely penetrating through the longitudinal wall 1122 is formed in the longitudinal wall 1122 and the air vent 1124 corresponds to the main part of the heating element in position, such that gas generated by heating and atomization of the heating element 111 flows out sequentially through the air hole 1123 and the air vent 1124.

[0058] The support 112 is made of an insulative material, and is inseparably or separably integrated with the heating element 111.

[0059] The transverse size of a liquid transfer unit 12 matches the transverse size of the compartment 15. The support 112 supports the bottom of the heating element 111; the transverse size of the heating element 111 matches the transverse size of the support 112, and preferably, the transverse size of the heating element 111 is equal to the transverse size of the support 112.

[0060] In some embodiments, referring to FIG. 3 and FIG. 11, the atomization assembly 1 comprises a liquid transfer unit 12, the compartment 15 is matched with the heating assembly 11 and the liquid transfer unit 12, and the liquid transfer unit 12 is disposed in the compartment 15 and is in contact with the main part 1111 of the heating element 111, such that liquid is transferred by the liquid transfer unit 12 to the main part 1111 to be heated and atomized. In some other embodiments, the support 112 is made of a material capable of transferring liquid, such as ceramic internally provided with many pores, the liquid transfer unit is omitted, and liquid is transferred by the support 112 to the heating element 111 to be atomized and heated.

[0061] Referring to FIG. 14-FIG. 16, an atomization device according to an embodiment of the present invention comprises a shell 2 and the above-described atomization assembly 1 disposed in the shell 2. The shell is provided with a liquid delivery structure and a gas outlet structure. The liquid delivery structure is communicated with the liquid transfer unit 12, such that liquid flows to the liquid transfer unit 12 through the liquid delivery structure, and is then transferred by the liquid transfer unit 12 to the heating element 111 to be heated and atomized to generate gas, which flows out through the gas outlet structure. Preferably, the liquid delivery structure comprises a liquid storage chamber 21, and the gas outlet structure comprises a gas outlet passage 22.

[0062] In summary, in the atomization assembly 1 and the atomization device, the electrodes 16 and the heating element 111 are electrically connected easily and reliably. A method of not welding leads may be adopted. The electrodes 16 are disposed on two sides of the heating element 111, and the side faces of the electrodes 16 are in contact with the electrical connection parts 1112 of the heating element 111.

[0063] The invention has the following advantages: [0064] 1.

[0065] 2. The contact portion of the electrode 16 in contact with the heating element 111 is located on the side face of the heating assembly 11, and is not affected by the size of upper and lower assembly structures, so poor contact caused by poor accuracy is avoided. [0066] 3. Generally, the number of the electrodes 16 is two, the two electrodes 16 are disposed on two sides of the heating assembly respectively, the contact portions of the electrodes 16 in contact with the heating element 111 are located on side faces of the electrical connection parts 1112 of the heating element 111, and the heating assembly is clamped between the side faces of the two electrodes 16, so good contact is realized, and the heating assembly 11 is fixed.

[0067] The above embodiments are merely preferred ones of the invention, and are not used to limit the invention. Those skilled in the art can make various modifications, combinations and changes to the invention. Any amendments, equivalent substitutions and improvements made based on the spirit and principle of the invention should fall within the scope of the claims.
