Description

Technical Field

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

[0002] The existing electronic atomization device mainly includes an atomizer and a power supply assembly. The power supply assembly is used to supply power to the atomizer. The atomizer is used to contain atomized liquids such as tobacco liquid and medicine liquid and heat them to generate atomized vapor for users to inhale. The atomizer generally includes a liquid storage tank and an atomization assembly. The liquid storage tank is used to contain atomized liquids such as tobacco liquid and medicine liquid. The atomization assembly is connected to the liquid storage tank so that the atomized liquid can reach the atomization assembly. The atomization assembly is used to heat the atomized liquid to generate atomized vapor after power is turned on for users to inhale. As the atomized liquid in the liquid storage tank continuously penetrates into the atomization assembly and is then atomized, negative pressure is formed in the liquid storage tank, resulting in difficulty in penetration, and the atomization assembly is prone to dry burning. If a ventilation channel is set between the atomization assembly and the liquid storage tank to balance the pressure difference between the inside and outside of the liquid storage tank, although it can improve the liquid penetration effect and slow down the dry burning phenomenon, the presence of the ventilation channel can easily cause the atomized liquid in the liquid storage tank to leak.

The power supply assembly 200 is used to supply power to the atomizer 100. The atomizer 100 is used to receive atomized liquids such as tobacco liquid and liquid medicine and heat them to generate atomized vapor for users to inhale. When the electronic atomization device is in a non-working state, such as during storage or transportation, the atomizer 100 is separated from the power supply assembly 200. Figure 1 When the electronic atomization device is in working state, the atomizer 100 cooperates with the power supply assembly 200. For example, the atomizer 100 can be inserted into the power supply assembly 200. Figure 2 In one embodiment, the explosion structure of the electronic atomization device is as shown in Figure 3 As shown, the atomizer 100 includes a housing 110 and an atomizer assembly 140 and a sliding member 170 located in the housing 110, wherein the atomizer assembly 140 includes a third sealing member 120, a liquid guide member 130, a first sealing member 150, an atomizer core 160 and a base 180. The structures of the atomizer assembly 140 and the sliding member 170 are as shown in FIG. Figure 4 When the atomizer 100 is separated from the power supply assembly 200, the longitudinal cross-sectional view of the atomizer 100 is as shown in FIG. Figure 5 As shown, Figure 6 for Figure 5The enlarged structural diagram of part A in FIG. 1 and the longitudinal cross-sectional view of the power supply assembly 200 are shown in FIG. Figure 7 As shown; after the atomizer 100 is inserted into the power assembly 200, the longitudinal cross-sectional view of the electronic atomization device is as shown Figure 8 As shown, Fig. 9 for Figure 8 Schematic diagram of the enlarged structure of part B.

[0044] like Figure 4 and Figure 5 As shown, a liquid storage bin 111 and an airway wall 112 are further provided in the housing 110, an air outlet channel 113 is formed in the airway wall 112, and the liquid storage bin 111 is used to contain the atomized liquid; the first sealing member 150 is sleeved on the outside of the atomizing core 160 and is located between the liquid guide member 130 and the atomizing core 160. The third sealing member 120 is sleeved on the outside of the liquid guide member 130 and is located between the liquid storage bin 111 and the liquid guide member 130. The outer wall of the third sealing member 120 is interference fit with the inner wall of the housing 110 to prevent the atomized liquid from leaking from the liquid storage bin 111. The third sealing member 120 is provided with a liquid conducting hole 121 and a second through hole 122; the end of the liquid conducting member 130 close to the third sealing member 120 is provided with a liquid conducting channel 131 and a vent hole 132, the liquid conducting channel 131 corresponds to the position of the liquid conducting hole 121, the position of the vent hole 132 corresponds to the position of the second through hole 122, the end of the airway wall 112 close to the liquid conducting member 130 passes through the second through hole 122 and is located in the vent hole 132, and the airway wall 112 and the third sealing member 120 are interference-fitted at the second through hole 122 to ensure the sealing of the connection. The internal structure of the liquid conducting member 130 is shown in FIG. Fig.10 As shown, an accommodating space 136 is disposed at one end of the liquid guiding member 130 close to the first sealing member 150 and the atomizing core 160 , and the first sealing member 150 and the atomizing core 160 are accommodated in the accommodating space 136 .

[0045] like Figure 3 , Figure 4 and Figure 5 As shown, the first sealing member 150 is provided with an air guide channel 154 on the side of the atomizer core 160. In other embodiments, the air guide channel 154 may not be provided on the first sealing member 150, for example, it may be provided on the liquid guide member 130. Figures 3 to 5In the illustrated embodiment, a first through hole 151 is provided at one end of the first sealing member 150 close to the liquid storage bin 111, i.e., at the top wall of the first sealing member 150, and the first through hole 151 is communicated with the liquid guide channel 131. One side of the top wall of the first sealing member 150 abuts against the accommodating space 136 of the liquid guide member 130, and the other side abuts against the top of the atomizer core 160. A liquid guide groove 161 is provided at the top of the atomizer core 160 corresponding to the position of the first through hole 151. The liquid storage bin 111 is communicated with the atomizer core 160 through the liquid guide hole 121 on the third sealing member 120, the liquid guide channel 131 on the liquid guide member 130, the first through hole 151 on the first sealing member 150, and the liquid guide groove 161 at the top of the atomizer core 160 in sequence, so that the atomized liquid in the liquid storage bin 111 can reach the atomizer core 160 for atomization. The top wall of the first sealing member 150 abuts against the accommodating space 136 of the liquid guiding member 130, so that the liquid guiding channel 131 on the liquid guiding member 130 is only connected to the first through hole 151 on the first sealing member 150, and the first through hole 151 further guides the atomized liquid in the liquid guiding channel 131 into the atomizing core 160. The first sealing member 150 is used to prevent the atomized liquid in the liquid guiding channel 131 from leaking to other places. In addition, the internal structure of the first sealing member 150 is as follows: Figure 5 and Fig.11 As shown, a vent groove 153 is provided on one side of the first sealing member 150 for contacting with the top of the atomizing core 160. One end of the vent groove 153 is connected to the air guide channel 154, and the other end is connected to the first through hole 151. The first through hole 151 is connected to the liquid guide channel 131 in the liquid guide member 130. Therefore, the air guide channel 154 can be connected to the liquid storage tank 111 through the vent groove 153, the first through hole 151, the liquid guide channel 131 and the liquid guide hole 121 in sequence. Figure 5 As shown, the ventilation groove 153 is located at the upper end of the liquid guiding groove 161 and the side of the first through hole 151, and the size of the ventilation groove 153 is very small relative to the size of the first through hole 151, thereby greatly reducing the risk of atomized liquid flowing into the air guiding channel 154.

[0046] In addition, if Figure 4 and Figure 6 As shown, a hook 135 is provided on the outer wall of one end of the liquid guide member 130 close to the first sealing member 150 and the atomizing core 160. The internal structure of the base 180 is as shown in FIG. Fig.12 As shown, a slot 181 is provided at one end of the base 180 close to the first sealing member 150 and the atomizing core 160, and the hook 135 and the slot 181 can cooperate with each other, so that the liquid guide member 130 and the base 180 are snap-fitted, as shown in FIG. Figure 6 As shown. Figure 5As shown, the first sealing member 150 and the atomizing core 160 are both disposed in the accommodation space 136 in the liquid guiding member 130, and an atomizing chamber 163 is formed between the atomizing core 160 and the base 180. When the atomizing core 160 is powered on, the atomized vapor generated by heating the atomized liquid is discharged into the atomizing chamber 163. Figure 4 and Fig.10 As shown, the outer wall of one end of the liquid guiding member 130 close to the first sealing member 150 and the atomizing core 160 is recessed inward to form an air flow channel 134 between the liquid guiding member 130 and the inner wall of the housing 110, and a transverse air channel 133 is also provided between the air flow channel 134 and the vent 132. One end of the air flow channel 134 is connected to the atomizing chamber 163, and the other end is connected to the vent 132 through the transverse air channel 133. Since the air channel wall 112 of the air outlet channel 113 close to one end of the liquid guiding member 130 is located in the vent 132, the atomizing chamber 163 is connected to the air outlet channel 113.

[0047] like Figure 5 and Fig. 9 As shown, the sliding member 170 is slidably disposed in the atomizing assembly 140 and has a first position and a second position relative to the atomizing assembly 140. When the atomizer 100 is separated from the power supply assembly 200, as shown in FIG. Figure 5 As shown, the sliding member 170 is located in the first position, and the sliding member 170 seals the air guide channel 154, that is, when the atomizer 100 is separated from the power supply assembly 200, for example, when the atomizer 100 is in a storage or transportation state, the sliding member 170 seals the air guide channel 154, thereby preventing the atomized liquid in the liquid storage tank 111 from flowing from the air guide channel 154 to the outside of the atomizer 100, reducing the risk of leakage of the atomizer 100 before use. When the atomizer 100 is inserted into the power supply assembly 200, the sliding member 170 is located in the second position, such as Fig. 9 As shown, the sliding member 170 is away from the air guide channel 154, so that the liquid storage tank 111 is connected to the outside atmosphere through the air guide channel 154. Since the atomizing chamber 163 is also connected to the atmosphere through the air inlet channel, the pressure difference between the liquid storage tank 111 and the atomizing chamber 163 tends to be balanced, which is conducive to alleviating the negative pressure formed in the liquid storage tank 111 as the liquid is consumed, so that the atomized liquid can penetrate into the atomizing core 160 normally, and the atomizing core 160 can be prevented from being dry-burned due to insufficient liquid supply.

[0048] In one embodiment, Figure 5 and Fig.12 As shown, a mounting hole 182 is provided in the base 180, and one end of the sliding member 170 away from the liquid storage tank 111 is slidably connected in the mounting hole 182, and the sliding member 170 can slide in the mounting hole 182. In one embodiment, the specific structure of the sliding member 170 Fig.13As shown, the sliding member 170 includes a first magnetic member 171 and an elastic member 175. The first magnetic member 171 includes a sealing head 172 and a connecting rod 173. The elastic member 175 is sleeved on the outside of the connecting rod 173. The transverse dimension of at least one section of the sealing head 172 is larger than the transverse dimension of the connecting rod 173, so that a first step surface 174 is formed between the sealing head 172 and the connecting rod 173. Figure 6 The internal structure of the mounting hole 182 is shown in FIG. Figure 6 As shown, the connecting rod 173 and the elastic member 175 are both located in the mounting hole 182, and the mounting hole 182 includes a first hole section 183 and a second hole section 184. The first hole section 183 is close to the liquid storage tank 111, and the lateral dimension of the first hole section 183 is larger than that of the second hole section 184, so that a second step surface 185 is formed between the first hole section 183 and the second hole section 184. The elastic member 175 is sleeved on the outside of the connecting rod 173 and compressed between the first step surface 174 and the second step surface 185. When the sliding member 170 is located at the first position relative to the atomizing assembly 140, as shown in FIG. Figure 5 and Figure 6 As shown, the sealing head 172 of the first magnetic member 171 abuts against and seals the air guide channel 154 .

[0049] It should be noted that in Figures 3 to 12 In the embodiment shown, a ventilation channel 152 is provided in the atomizer, and the ventilation channel 152 is specifically provided in the atomizing assembly 140, one end of the ventilation channel 152 is connected to the air inlet channel, and can be connected to the outside atmosphere through the air inlet channel, and the other end of the ventilation channel 152 is connected to the liquid storage tank 111; the ventilation channel 152 includes a mounting hole 182 in the base 180, an air guide channel 154 in the first sealing member 150, a ventilation groove 153, a first through hole 151, a liquid guide channel 131 and a liquid guide hole 121, that is, the ventilation channel 152 is at least partially provided in the first sealing member 150. When the sliding member is in the first position, the sliding member 170 seals the air guide channel 154, and then seals the ventilation channel 152; when the sliding member 170 is in the second position, the sliding member 170 opens the air guide channel 154, that is, opens the ventilation channel 152, and then the liquid storage tank 111 is connected to the outside atmosphere through the ventilation channel 152.

[0050] In addition, if Figure 5 and Fig.12 As shown, the base 180 is also provided with a first sleeve 187 and an air inlet channel 186, the lead 162 of the atomizing core 160 is inserted into the first sleeve 187, and the air inlet channel 186 is connected to the atomizing chamber 163. Figure 7 As shown, the power supply assembly 200 includes a main housing 210, an electrode 230, a second magnetic member 220 and a power supply ( Figure 7The electrode 230 and the second magnetic member 220 are both located in the main housing 210, and the electrode 230 is electrically connected to the power supply. A receiving cavity 211 is also provided above the electrode 230 and the second magnetic member 220 in the main housing 210 for inserting the atomizer 100. The structure after the atomizer 100 is inserted into the power supply assembly 200 is as follows: Figure 8 and Fig. 9 As shown, the main housing 210 is provided with an air inlet 212, and external air enters the air inlet channel 186 through the air inlet 212 and the gap between the atomizer 100 and the power supply assembly 200, and then enters the atomizing chamber 163, and the atomized vapor in the atomizing chamber 163 is taken out of the electronic atomizing device through the air flow channel 134 between the liquid guide 130 and the inner wall of the housing 110, the vent 132 and the air outlet channel 113 for the user to inhale. Fig. 9 As shown, when the atomizer 100 is inserted into the power supply assembly 200, the second magnetic member 220 is magnetically attracted to the first magnetic member 171, thereby pulling the sliding member 170 to slide downward, the elastic member 175 is further compressed, and the first magnetic member 171 slides from the first position to the second position, thereby making the sealing head 172 away from the air guide channel 154, the ventilation channel 152 is opened, and the liquid storage tank 111 is connected to the air inlet 212 through the ventilation channel 152.

[0051] In a preferred embodiment, Fig. 9 and Fig.13 As shown, the sliding member 170 also includes a second sealing member 176, which is sleeved on the outside of the connecting rod 173, and the second sealing member 176 abuts against the first step surface 174, and the elastic member 175 is compressed between the second step surface 185 and the second sealing member 176; the second sealing member 176 slides with the connecting rod 173, and when the sliding member 170 is located in the second position, the second sealing member 176 seals the upper end of the mounting hole 182, thereby preventing the liquid in the liquid storage tank 111 from flowing out of the atomizer 100 from the air guide channel 154 and the mounting hole 182.

[0052] In a specific embodiment, the elastic member 175 may be a spring, the entire material of the second magnetic member 220 or the partial material close to the first magnetic member 171 may be a magnet, and the entire material of the first magnetic member 171 or the partial material close to the second magnetic member 220 may be iron, ferrite, magnet, or any other material that can be attracted by a magnet. In another embodiment, the entire material of the first magnetic member 171 or the partial material close to the second magnetic member 220 may be a magnet, and the entire material of the second magnetic member 220 or the partial material close to the first magnetic member 171 may be iron, ferrite, magnet, or any other material that can be attracted by a magnet.

[0053] In addition, in the above-mentioned embodiment, the elastic member 175 is compressed between the first step surface 174 and the second step surface 185. It can be understood that in other embodiments, the first step surface 174 may not be provided on the first magnetic member 171, one end of the elastic member 175 is connected to the sealing head 172, and the second step surface 185 may not be provided in the mounting hole 182 of the base 180. Instead, a stopper is provided in the mounting hole 182, and the stopper protrudes toward the interior of the mounting hole 182 and does not hinder the connecting rod 173 from sliding in the mounting hole 182. The elastic member 175 is compressed between the sealing head 172 and the stopper.

[0054] In addition, in the above embodiment, the sliding member 170 includes a first magnetic member 171, and the power supply assembly 200 is provided with a second magnetic member 220 that is magnetically attracted to the first magnetic member 171. After the atomizer 100 is inserted into the power supply assembly 200, the sliding member 170 slides from the first position to the second position under the action of the magnetic attraction. It can be understood that in the present invention, the driving force for the sliding member 170 to slide from the first position to the second position may not be limited to the magnetic attraction. For example, in one embodiment, an operating handle connected to the sliding member 170 may be provided on the outside of the electronic atomization device. After the atomizer 100 is assembled during production, the sliding member 170 is located in the first position. After the atomizer 100 is inserted into the power supply assembly 200, the user can manually operate the handle to slide the sliding member 170 from the first position to the second position. Alternatively, in another embodiment, a driving member may be provided in the power assembly 200. When the atomizer 100 is inserted into the power assembly 200, the driving member is connected to the sliding member 170 and drives the sliding member 170 to slide from the first position to the second position.

[0055] In another embodiment, the longitudinal cross-sectional view of the atomizer before being matched with the power supply assembly when the sliding member 170 is located in the first position is as shown in FIG. Fig.14 As shown, the longitudinal cross-sectional view of the atomizer when it is matched with the power supply assembly and the sliding member 170 is located in the second position is as shown in Fig.15As shown. A connecting hole 310 is provided in the liquid guide member 130, and the atomizer further includes a second sleeve 320, one end of the second sleeve 320 is connected to the base 180, and the other end is arranged in the connecting hole 310, one end of the connecting hole 310 is connected to the liquid storage chamber 190, and the other end is connected to the mounting hole 182 through the second sleeve 320, and the ventilation channel 152 includes the connecting hole 310, the second sleeve 320 and the mounting hole 182; one end of the sliding member 170 is slidably connected in the mounting hole 182, and the other end is located in the second sleeve 320. The sliding member 170 includes a sliding rod 330 and an elastic member 175, and the sliding rod 330 includes a first rod segment 331 and a second rod segment 332, the transverse dimension of the first rod segment 331 is smaller than that of the second rod segment 332, and the first rod segment 331 is slidably connected in the mounting hole 182, and there is a gap between the outer wall of the first rod segment 331 and the inner wall of the mounting hole 182. When the atomizer is not matched with the power supply assembly, such as Fig.14 As shown, when the elastic member 175 is in the first position, the second rod segment 332 seals the gap between the mounting hole 182 and the first rod segment 331, thereby sealing the ventilation channel 152; when the atomizer is matched with the power supply assembly, as shown in FIG. Fig.15 As shown, the sliding member 170 slides upward under the support of the power supply assembly, the elastic member 175 is compressed, the sliding member 170 is in the second position, and the second rod segment 332 opens the gap between the mounting hole 182 and the first rod segment 331, thereby opening the ventilation channel 152. The ventilation channel 152 is connected to the outside atmosphere through the air intake channel of the atomizer, and the air intake channel of the atomizer can be the matching gap between the atomizer and the power supply assembly.

[0056] In addition, if Fig.14 and Fig.15 As shown, the atomizer also includes a connecting end 340, which is arranged in one end of the second sleeve 320 away from the liquid storage bin, and the elastic member 175 is supported between the connecting end 340 and the sliding rod 330. A third through hole 341 is provided in the connecting end 340, and the communicating hole 310 is connected to the second sleeve 320 through the third through hole 341. It should be noted that the through hole size here is relatively small, for example, the aperture is below 0.6mm, preferably 0.4mm-0.6mm. Since the liquid easily forms a surface tension film on the surface, the liquid can be prevented from flowing out of the atomization bin, but the airflow can break through the surface tension film and enter the liquid storage bin during suction, so as to achieve the purpose of depressurizing the liquid storage bin. Therefore, by providing the connecting end 340 and providing the third through hole 341 in the connecting end 340, the liquid storage chamber 190 can be connected to the outside atmosphere through the ventilation channel 152, and the atomized liquid in the liquid storage chamber 190 can be prevented from flowing out of the ventilation channel 152.

[0057] The atomizer 100 and the electronic atomization device of the present invention are provided with a ventilation channel 152 and a sliding member 170 that can slide relative to the atomization component 140 in the atomization component 140. Before the atomizer 100 and the electronic atomization device are used, such as during storage or transportation, the sliding member 170 is located in the first position. The sliding member 170 seals the ventilation channel 152, thereby preventing the atomized liquid in the liquid storage tank 111 from flowing out of the ventilation channel 152, thereby reducing the risk of leakage of the atomizer 100 before use. When the atomizer 100 and the electronic atomization device are in use, the sliding member 170 is located in the second position, and the sliding member 170 opens the ventilation channel 152 so that the liquid storage tank 111 is connected to the outside atmosphere through the ventilation channel 152. The pressure difference between the inside and outside of the liquid storage tank 111 tends to be balanced. In the process of the atomized liquid penetrating into the atomization component 140, the negative pressure formed in the liquid storage tank 111 due to the liquid consumption is relieved, and the atomized liquid penetrates into the atomization core 160 normally, thereby avoiding dry burning.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0059] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
