Detailed Description

In order to facilitate an understanding of the present application, the present application will be described in more detail below with reference to the accompanying drawings and detailed description. The specific embodiments are to be considered in an illustrative sense, and not a limiting sense. In addition, for convenience of description, only some, but not all of the structures related to the present application are shown in the drawings.

The embodiment of the application provides an atomizer. Referring to fig. 1 to 7, the atomizer 100 includes a liquid storage portion 110, an atomizing member 120, a sealing member 130, and a nozzle member 140.

As shown in fig. 2 and 7, the liquid storage portion 110 has a liquid storage chamber 111 defined therein. The reservoir 111 is used for storing a liquid matrix. The opposite ends of the liquid storage part 110 are provided with a liquid injection port 112 and a liquid outlet 113. The liquid injection port 112 and the liquid outlet 113 are both communicated with the liquid storage cavity 111. As shown in fig. 7, the liquid filling port 112 and the liquid outlet 113 are provided at both ends of the liquid storage portion 110 in the longitudinal direction, respectively. The liquid filling port 112 is used for filling the liquid medium into the liquid storage cavity 111. The liquid outlet 113 is used for allowing the liquid matrix in the liquid storage cavity 111 to flow out. The liquid matrix in the liquid storage chamber 111 flows from the liquid outlet 113 to the atomizer 120. The atomizer 120 is disposed adjacent to the liquid outlet 113, and the atomizer 120 heats and atomizes the liquid matrix to form an aerosol. The liquid matrix may comprise, for example, one or more of the components glycerol, propylene glycol, nicotine formulations, fragrances, flavoring additives, and the like, although other types of liquid matrices are also possible.

As shown in fig. 2, a seal 130 is used to seal the fill port 112. As shown in fig. 2 and 4, the sealing member 130 includes a flange 131 extending radially outward, and the flange 131 abuts against an end face a of the liquid storage portion 110 adjacent to the liquid filling port 112, so that the sealing member 130 covers the liquid filling port 112 to seal the liquid storage chamber 111. The flange 131 is arranged to abut against the end face A of the liquid injection port 112 to seal the liquid storage cavity 111, so that an end face sealing structure is formed, and the sealing member 130 is pressed by the suction nozzle member 140.

In the present embodiment, the sealing member 130 is disposed on the nozzle member 140. That is, the sealing member 130 is preassembled with the nozzle member 140 into one assembly and then mounted to the liquid storage portion 110. When the liquid storage device is used, after the liquid matrix is injected into the liquid storage cavity 111, the preassembled suction nozzle piece 140 and the preassembled sealing piece 130 are directly installed on the liquid storage portion 110, and the sealing piece 130 and the suction nozzle piece 140 are not required to be installed on the liquid storage portion 110 respectively, so that the installation steps are reduced, the installation operation after liquid injection is convenient for a user, and meanwhile, the probability of installation errors is reduced.

As shown in fig. 2, the suction nozzle member 140 is disposed on the liquid storage portion 110 by a top end cap of the liquid storage portion 110, one end of the suction nozzle member 140 is opened, and the liquid storage portion 110 extends into the suction nozzle member 140 from the opened end of the suction nozzle member 140. The housing of the outer circumference of the suction nozzle member 140 surrounds a portion of the outer side surface of the liquid storage part 110, and a sealing ring 145 is provided between the suction nozzle member 140 and the liquid storage part 110. The sealing ring 145 is disposed between the inner sidewall of the suction nozzle 140 and the inner sidewall of the liquid storage portion 110.

With continued reference to fig. 2, the nozzle member 140 is connected to the liquid storage portion 110 by a snap-fit structure. So that the suction nozzle member 140 is fixed to the liquid storage portion 110. The fastening structure provides a longitudinal tension force to the suction nozzle 140, so that the suction nozzle 140 presses the flange 131 of the sealing member 130 against the liquid storage portion 110, and the sealing effectiveness of the sealing member 130 is ensured.

Specifically, as shown in fig. 2, the fastening structure is located on the inner side of the nozzle member 140. The inner side wall of the suction nozzle 140 is provided with a bayonet 146, the outer side wall of the liquid storage part 110 is provided with a buckle 116, and the buckle 116 and the bayonet 146 are matched to form a buckle structure, so that the suction nozzle 140 is fixed on the liquid storage part 110. The bayonet 146 on the suction nozzle 140 is arranged at the inner side of the suction nozzle 140, so that the buckling position is hidden at the inner side of the suction nozzle 140, and a non-detachable connection structure is formed between the suction nozzle 140 and the liquid storage part 110, so that the sealing effectiveness of the sealing element 130 is higher.

Meanwhile, after the suction nozzle member 140 is connected with the liquid storage portion 110 through the fastening structure, non-detachable connection is formed, and the suction nozzle member 140 is mounted on the liquid storage portion 110 and cannot be detached from the liquid storage portion 110, so that the safety performance of the atomizer is guaranteed, and liquid matrixes are not caused to flow out due to the fact that the atomizer is opened by mistake by a child.

As shown in fig. 2, the snap-fit structure is closer to the open end of the nozzle member 140 than the sealing ring 145.

As shown in fig. 2 and 6, the suction nozzle 140 is provided with a pressing portion 141, and the pressing portion 141 abuts against a side of the flange 131 away from the liquid storage portion 110 in a direction approaching the liquid storage portion 110 to press the flange 131 against the end face a of the liquid storage portion 110, and a projection of the pressing portion 141 in the longitudinal direction overlaps at least partially with the end face a of the liquid storage portion 110, so that the flange 131 can be pressed against the end face a of the liquid injection port 112 to form an end face seal. The end face seal is more reliable and more effective than the axial and radial seal described in the background. Meanwhile, the liquid pressing amount during liquid injection can be reduced.

Alternatively, the projection of the pressing portion 141 in the longitudinal direction covers the end face a of the liquid storage portion 110. The projection of the pressing part 141 in the longitudinal direction completely covers the end face a of the liquid storage part 110, so that the pressing part 141 is pressed on the whole end face of the liquid storage part 110, and the sealing effect is better.

Referring to fig. 4, the seal 130 further includes a boss 132. Referring to fig. 2, a boss 132 extends from one side of the flange 131, the boss 132 extending at least partially into the reservoir 111. The boss 132 may act as a detent to prevent displacement of the seal 130.

Alternatively, the width of the boss 132 is smaller than the width of the pouring spout 112, or the diameter of the boss 132 is smaller than the diameter of the pouring spout 112. When the boss 132 is cylindrical, the diameter of the boss 132 is smaller than the diameter of the liquid inlet 112, and when the boss 132 is not cylindrical but has another shape, the width of the boss 132 is set smaller than the width of the liquid inlet 112. In short, the cross-sectional dimension of the boss 132 is smaller than the dimension of the liquid inlet 112, so that the size of the boss 132 is smaller than the size of the liquid inlet 112, and the boss 132 does not fit too tightly with the liquid inlet 112, and may even have a gap. This reduces the liquid pressure caused by the boss 132 getting stuck in the liquid storage chamber 111 during assembly. If the boss 132 is too tightly clamped to the liquid storage cavity 111, as described in the background art, in the comparison document, the seal 130 is assembled with the liquid storage cavity 111 in an interference manner to form a radial seal, which can result in serious liquid pressing, and the liquid matrix is pressed outwards by too large pressure in the liquid storage cavity 111.

Optionally, as shown in fig. 4, the outer sidewall of the boss 132 is provided with a vent slot 1321, and the vent slot 1321 extends longitudinally and terminates in the flange 131. When the boss 132 extends into the liquid storage cavity 111, the air exhaust groove 1321 on the boss 132 can perform an air exhaust function in the assembly process, so that the boss 132 is prevented from being difficult to be installed into the liquid storage cavity 111, and the assembly is smoother. It will be appreciated that the end of the exhaust slot 1321 extends through the end face of the boss 132, thereby allowing the gas in the exhaust slot 1321 to be exhausted from the end face of the exhaust slot 1321.

Referring to fig. 2, 5 and 6, one of the sealing member 130 and the suction nozzle 140 is provided with a plug 142, and the other is provided with a slot 133, as shown in fig. 2, the plug 142 is inserted into the slot 133, and the plug 142 is in interference fit with the slot 133, so that the sealing member 130 is fixed on the suction nozzle 140 to form a whole, and the assembly steps can be reduced.

In the embodiment of the present application, as shown in fig. 2, the post 142 is disposed on the suction nozzle 140, and the slot 133 is disposed on the sealing member 130.

Further alternatively, as shown in fig. 5, a plug 134 is provided in the slot 133, and as shown in fig. 6, a socket 143 is provided on the post 142. As shown in fig. 3, the plug 134 is inserted into the insertion hole 143, and the plug 134 is in interference fit with the insertion hole 143, so that the sealing member 130 is further connected with the suction nozzle member 140, and the connection strength of the sealing member and the suction nozzle member is enhanced. That is, the engagement of the post 142 with the slot 133 and the engagement of the pin 134 with the receptacle 143 form two connections that tightly attach the seal 130 to the nozzle 140.

In the embodiment of the present application, as shown in fig. 2, the post 142 is disposed on the suction nozzle 140, and the slot 133 is disposed on the sealing member 130. The slot 133 extends from the end face of the end of the seal 130 remote from the reservoir 111 toward the end face of the boss 132. I.e., the slot 133 is provided at the rear surface of the boss 132 and extends into the boss 132. As shown in fig. 2, the groove bottom B of the insertion groove 133 is lower than the end face a of the liquid filling port 112, so that after the insertion of the insertion post 142 into the insertion groove 133, one end of the insertion post 142 inserted into the insertion groove 133 is lower than the end face a of the liquid filling port 112, that is, the insertion post 142 protrudes into the liquid storage chamber 111 in the longitudinal direction. This allows the boss 132 to be secured by the post 142. Since the sealing member 130 is made of rubber or silica gel, it is soft and easy to deform. The boss 132 is fixed by the plug-in posts 142 on the suction nozzle 140, so that the boss 132 is prevented from deforming, and the limit effect of the boss 132 in the liquid injection port 112 is better.

As shown in fig. 2 and 7, the liquid storage portion 110 is provided with an air outlet passage 114. The air outlet air passage 114 is arranged in parallel with the liquid storage cavity 111, and the air outlet air passage 114 is arranged at two sides of the liquid storage cavity 111. As shown in fig. 7, the liquid storage part 110 is provided with an atomization cavity 115, and the atomization cavity 115 is used for atomizing a liquid substrate by the atomizer 120. As shown in fig. 7, one end of the air outlet channel 114 is communicated with the atomizing chamber 115, and the other end is communicated with the end face of the liquid storage part 110, which is provided with the liquid injection port 112. It will be appreciated that, as shown in fig. 2, the outlet air duct 114 communicates with the nozzle opening 144 of the nozzle member 140, thereby forming an outlet air duct.

As shown in fig. 2, the edge of the pressing portion 141 on the suction nozzle 140 and the edge of the sealing member 130 are substantially flush with the sidewall of the air outlet channel 114, so as to avoid interfering with the outflow of the air outlet channel 114.

As shown in fig. 2, the top surface C of the pressing portion 141 of the nozzle member 140 is an inclined surface, and the inclined direction can guide the air flow from the air outlet duct 114 to the nozzle opening 144 of the nozzle member 140, thereby facilitating the outflow of the air flow.

The embodiment of the application also provides an electronic atomization device 200. As shown in fig. 4, the electronic atomizing device 200 includes the above-described atomizer 100, and further includes a battery assembly 210. The battery assembly 210 is used for supplying power to the atomizer 100, and the atomizer 100 can heat and atomize the liquid matrix after being powered on to form aerosol for a user to inhale.

As shown in fig. 9 a, when the electronic atomizing device 200 according to the embodiment of the present application is manufactured as a product, the sealing member 130 is installed in the nozzle member 140 to form a unit. When the user uses the suction nozzle member 140, after the liquid is injected into the liquid storage portion 110, the suction nozzle member 140 is directly fastened on the liquid storage portion 110, and then the installation is completed, as shown in a b diagram in fig. 9.
