Description

Technical Field

[0001] This application relates to the field of atomization technology, and in particular to a liquid supply bottle and an electronic atomizer. Background Technology

[0002] High-capacity electronic atomizers typically include a supply bottle, which supplies liquid to the reservoir containing the atomizing components. Because the supply bottle is a closed system, during the supply process, as liquid flows out, the internal pressure gradually decreases, while the internal pressure in the reservoir gradually increases as liquid flows in. This pressure difference slows down the supply rate and can even lead to insufficient liquid supply.

[0003] Chinese patent CN222303104U discloses an electronic atomizing device, including...

[0004] The device includes a shell, an atomizing module, and an e-liquid bottle. One end of the shell has a suction section, and an air inlet is located on the shell. The atomizing module and the e-liquid bottle are housed within the shell. The atomizing module has a liquid storage chamber. The shell has a clearance notch at the e-liquid bottle location. The e-liquid bottle has an oil guiding section, the free end of which extends into the atomizing module and communicates with the liquid storage chamber. The air outlet of the atomizing module communicates with the suction section. The shell also has an air inlet, which communicates with the air inlet of the atomizing module. At least one ventilation section is formed on the e-liquid bottle. As the e-liquid continues to atomize, the amount of e-liquid in the bottle decreases, creating a negative pressure state. External air can flow into the e-liquid bottle through the ventilation section, maintaining the pressure balance within the bottle and ensuring that the e-liquid is smoothly delivered to the atomizing module. This solves the problem of insufficient oil intake and dry burning, guaranteeing atomization performance. However, this structure is relatively complex and has a high manufacturing cost. Utility Model Content

[0005] The main objective of this application is to provide a liquid supply bottle and an electronic atomizer to solve the technical problem that the liquid supply bottle and assembled components cannot exchange air.

[0006] To achieve the above objectives, the first aspect of this application provides a liquid supply bottle, the liquid supply bottle comprising:

[0026] In the liquid supply bottle of this application, when the bottle is inverted, i.e., when the opening is facing downwards, the atomizing matrix inside the bottle is mainly guided out of the bottle by the liquid guiding medium.

[0043] This application discloses a liquid supply bottle, comprising a bottle body, a stopper, a liquid guiding medium, and a sleeve. One end of the bottle body has an opening for storing an atomizing matrix. The stopper covers the opening, and a portion of the stopper extends away from the bottle body to form a connector. The connector has a through-hole forming an injection channel connecting the inner cavity of the bottle body to the outside. A portion of the inner wall of the injection channel is recessed outward to form a venting channel, which extends at least partially axially along the injection channel. The liquid guiding medium is disposed in the injection channel and is used to guide the atomizing matrix from the bottle body to the outside. The liquid guiding medium expands after absorbing liquid. The sleeve is fitted between the liquid guiding medium and the injection channel and does not seal the venting channel. The sleeve is made of a rigid material and is used to prevent the liquid guiding medium from absorbing liquid, expanding, and filling the venting channel.

[0044] In the liquid supply bottle of this application, when the bottle is inverted, i.e., when the opening is facing downwards, the atomizing matrix inside the bottle is mainly guided by the liquid guiding medium to flow out of the bottle (a small amount flows out through the venting channel). When the bottle is upright, the air inside the bottle flows out through the venting channel, thus enabling the liquid supply bottle of this application to supply liquid and exchange air. The sleeve prevents the liquid guiding medium from absorbing liquid, expanding, and filling the venting channel, thereby ensuring smoother air exchange between the bottle and other components.

[0045] Please see Figures 1 to 9 The following will mainly describe the specific structure of the liquid supply bottle 100.

[0046] The liquid supply bottle 100 of this application includes a bottle body 110, the top of which is open, and the bottle body 110 is used to store the atomizing matrix. The bottle body 110 can be made of materials such as plastic, metal or glass.

[0047] The liquid supply bottle 100 of this application includes a stopper 120, which covers the opening. The stopper 120 and the opening can be sealed together. A portion of the stopper 120 extends away from the bottle body 110 to form a connector 121. The connector 121 has a through-hole forming a liquid injection channel 122 that connects the inner cavity of the bottle body 110 and the outside, that is, the connector 121 is generally cylindrical. The connector 121 can be cylindrical, square, racetrack-shaped, or irregularly shaped, without specific limitation.

[0048] A portion of the inner wall of the injection channel 122 is recessed outward to form a ventilation channel 123, which connects the inner cavity of the bottle body 110 to the outside atmosphere. The ventilation channel 123 may extend at least partially along the axial direction of the insertion part 121, and the ventilation channel 123 may be a straight channel, a curved channel, or a spiral channel.

[0049] The ventilation channel 123 in this application is used for ventilation. The ventilation channel 123 is relatively small in size, and its ability to carry the atomized matrix is ​​limited. When the liquid supply bottle 100 is inverted, the atomized matrix in the bottle body 110 mainly flows out through the liquid guiding medium 130. The microporous network structure of the liquid guiding medium 130 can control the flow rate of the atomized matrix, so that over-injection will not occur.

[0050] The liquid supply bottle 100 of this application includes a liquid guiding medium 130, which is disposed in the liquid injection channel 122. The liquid guiding medium 130 is used to guide the atomizing matrix of the bottle body 110 to the outside. The liquid guiding medium 130 has a microporous network structure, thereby enabling the liquid guiding medium 130 to guide liquid and allow air to pass through. Furthermore, the liquid guiding medium 130 expands after absorbing liquid.

[0051] The liquid supply bottle 100 of this application includes a sleeve 140, which is fitted between the liquid-conducting medium 130 and the liquid injection channel 122 and does not seal the ventilation channel 123. The sleeve 140 is made of a rigid material and is used to prevent the liquid-conducting medium 130 from absorbing liquid, expanding, and filling the ventilation channel 123. By preventing the liquid-conducting medium 130 from absorbing liquid, expanding, and filling the ventilation channel 123, the ventilation between the bottle body 110 and the outside environment can always be relatively smooth. The sleeve 140 can be made of materials such as plastic, metal, or glass.

[0052] Understandably, to achieve the ventilation function of the ventilation channel 123, the positions of both ends of the ventilation channel 123 are adapted to the positions of both ends of the sleeve 140. In some embodiments, the end of the sleeve 140 away from the bottle body 110 is flush with the end of the injection channel 122 away from the bottle body 110, or the end of the sleeve 140 away from the bottle body 110 extends beyond the end of the injection channel 122 away from the bottle body 110, and the end of the ventilation channel 123 away from the bottle body 110 passes through the end face of the end of the injection channel 122 away from the bottle body 110, thereby enabling the ventilation channel 123 to communicate with the outside. In other embodiments, the end of the sleeve 140 away from the bottle body 110 is located inside the end of the injection channel 122 away from the bottle body 110, and the end of the ventilation channel 123 away from the bottle body 110 is further away from the bottle body 110 than the end of the sleeve 140 away from the bottle body 110, thereby preventing the ventilation channel 123 from being closed by the sleeve 140. The arrangement of the end of the sleeve 140 near the inner cavity of the bottle body 110 and the end of the ventilation channel 123 near the inner cavity of the bottle body 110 are similar to the arrangement of the ends away from the bottle body 110, and will not be described again.

[0053] The end of the liquid guiding medium 130 furthest from the bottle body 110 can extend beyond the end of the sleeve 140 furthest from the bottle body 110, or it can be located inside the end of the sleeve 140 furthest from the bottle body 110, or it can be flush with the end of the sleeve 140 furthest from the bottle body 110. The end of the sleeve 140 furthest from the bottle body 110 can extend beyond the end of the injection channel 122 furthest from the bottle body 110, be located inside the end of the injection channel 122 furthest from the bottle body 110, or be flush with the end of the injection channel 122 furthest from the bottle body 110.

[0054] A limiting ring plate 124 is fitted onto the inner wall of the injection channel 122. The limiting ring plate 124 and the inner wall of the injection channel 122 can be integrally formed, that is, the limiting ring plate 124 can be formed by extending inward from the inner wall of the injection channel 122. The limiting ring plate 124 and the inner wall of the injection channel 122 can also be detachably connected, such as by snap-fit, adhesive, or screw connection. The limiting ring plate 124 is annular and will not excessively obstruct the flow of liquid. The end of the sleeve 140 near the bottle body 110 is connected to the side of the limiting ring plate 124 facing outward. The sleeve 140 and the limiting ring plate 124 can abut against each other.

[0055] The end of the ventilation channel 123 closer to the inner cavity of the bottle body 110 is closer to the inner cavity of the bottle body 110 than the limiting ring plate 124, thus the ventilation function of the ventilation channel 123 is not blocked by the limiting ring plate 124. The limiting ring plate 124 has a notch 125 corresponding to the ventilation channel 123, and the notch 125 connects the interior of the ventilation channel 123 and the limiting ring plate 124. Therefore, the limiting ring plate 124 does not block the connection between the ventilation channel 123 and the liquid injection channel 122. The sleeve 140 and the liquid guiding medium 130 are connected to the ventilation channel 123, and the gas in the sleeve 140 and the liquid guiding medium 130 can be discharged through the ventilation channel 123, thereby improving the ventilation effect of the liquid supply bottle 100.

[0056] In some embodiments, the liquid guiding medium 130 is hollowed out to form a through groove 131, which extends axially along the injection channel 122 and penetrates both ends of the liquid guiding medium 130. That is, one end of the through groove 131 is connected to the inner cavity of the bottle body 110, and the other end is connected to the outside. The through groove 131 is connected to the inner wall of the sleeve 140, that is, the through groove 131 is hollowed out on one side of the liquid guiding medium 130, and the through groove 131 can still connect the inner cavity of the bottle body 110 and the outside after the liquid guiding medium 130 absorbs liquid and expands. Compared with a groove hollowed out inside the liquid guiding medium 130, the through groove 131 is less likely to be squeezed closed by the liquid guiding medium 130 after it absorbs liquid and expands (the liquid guiding medium 130 is limited by the outer sleeve 140 and can only be squeezed inward). A liquid passage hole 126 is provided on the limiting ring plate 124, which is opposite to and connected to the through groove 131. When the supply bottle 100 is inverted, the atomizing matrix inside the bottle body 110 can also flow out through the channel 131, thus improving the supply effect of the bottle body 110. When the supply bottle 100 is upright, the gas in the bottle body 110 can also flow out through the channel 131, thus improving the ventilation effect of the bottle body 110.

[0057] The number of injection channels 122, venting channels 123, and liquid guiding media 130 can be two, with each channel corresponding to the other. The two venting channels 123 are located on the side of the two injection channels 122 that are closer to each other, and the two through slots 131 are located on the side of the two injection channels 122 that are farther from each other. This results in better connection stability and deformation resistance between the insertion part 121 and the limiting ring plate 124. The symmetrical layout of the notch 125 and the liquid passage hole 126 allows for a more uniform force distribution on the limiting ring plate 124 when it bears a load, reducing the risk of localized stress concentration.

[0058] The portions of the two injection channels 122 and the two ventilation channels 123 near the inner cavity of the bottle body 110 are connected to form a main channel 128. The end of the main channel 128 away from the inner cavity of the bottle body 110 is located at the limiting ring plate 124. This arrangement allows the insertion part 121 to have a relatively large gas-liquid flow rate, thereby improving the liquid supply and ventilation effect of the liquid supply bottle 100.

[0059] The liquid supply bottle 100 of this application includes an inner cap 150, which covers the end of the insertion portion 121 away from the bottle body 110. The inner cap 150 is used to seal the connection between the liquid injection channel 122, the ventilation channel 123, and the liquid guiding medium 130 and the outside environment. The inner cap 150 can be a cylindrical shape with one end sealed, and its shape is adapted to the shape of the insertion portion 121. The inner cap 150 can be made of an elastic material, such as silicone, plastic, and / or rubber, so that the connection between the inner cap 150 and the insertion portion 121 is relatively tight, thereby effectively sealing the liquid injection channel 122, the ventilation channel 123, and the liquid guiding medium 130.

[0060] The liquid supply bottle 100 of this application includes an outer cap 160, which covers the inner cap 150 and the end of the bottle stopper 120 away from the bottle body 110. An installation opening 161 is provided on the portion of the outer cap 160 opposite to the bottle stopper 120. The liquid supply bottle 100 of this application includes a locking member 170, which is at least partially disposed within the installation opening 161. The locking member 170 includes a swing plate 172 and two connecting shafts 171. One end of each connecting shaft 171 is connected to opposite sides of the swing plate 172, and the other end is connected to the opposite walls of the installation opening 161. The swing plate 172 includes an operating end 173 and a connecting end 174. A gap exists between the operating end 173 and the bottle stopper 120, and the connecting end 174 is used to connect to the bottle stopper 120. The two connecting shafts 171 are capable of torsional deformation, allowing the swing plate 172 to swing back and forth around the connecting shafts 171 under external force. The swing plate 172 has an unlocked state where the operating end 173 is close to the bottle stopper 120 and the connecting end 174 is away from the bottle stopper 120, and a locked state where the operating end 173 is away from the bottle stopper 120 and the connecting end 174 is connected to the bottle stopper 120. In the unlocked state, the operating end 173 and the bottle stopper 120 can be spaced apart or abutted against each other, and the connecting end 174 and the bottle stopper 120 are spaced apart. In the locked state, the operating end 173 and the bottle stopper 120 are spaced apart, and the connecting end 174 and the bottle stopper 120 are connected to each other.

[0061] In some embodiments, in the locked state, the connecting end 174 engages with the bottle stopper 120. One of the connecting end 174 and the bottle stopper 120 has a latch 175, and the other has a locking block 127; the latch 175 and the locking block 127 engage. See also... Figure 1 and Figure 2 In some embodiments, the bayonet 175 is provided at the connecting end 174, and the locking block 127 is provided at the bottle stopper 120.

[0062] The locking component 170 can be made of plastic material. Plastic material possesses a certain degree of elasticity and rigidity, enabling the aforementioned technical effects. The locking component 170 and the outer cover 160 can be integrally molded. Integral molding eliminates the weaknesses of spliced ​​structures, allowing the torsional and shear forces borne by the connecting shaft 171 to be directly transmitted to the entire outer cover 160 through the material itself, rather than being limited to local connection points. This fundamentally reduces the risk of failure such as breakage at the root of the connecting shaft 171 and cracking at the connection points of the outer cover 160. When the connecting shaft 171 is subjected to external torsion, the integrally molded structure forms a cohesive load-bearing system for the connecting shaft 171 and the outer cover 160. The torque of the connecting shaft 171 diffuses to the entire outer cover 160 through the continuity of the material. The large-area structure of the outer cover 160 acts as a force buffer, dispersing locally concentrated torque into the deformation potential energy of the entire outer cover 160, preventing excessive stress accumulation at the transition area between the connecting shaft 171 and the outer cover 160. Furthermore, the integral molding manufacturing method is relatively simple and convenient.

[0063] In some embodiments, there are two mounting ports 161 and two locking members 170, with each mounting port 161 and locking member 170 arranged in a one-to-one correspondence. The two mounting ports 161 are located on opposite sides of the outer cover 160. As a result, the connection between the locking member 170 and the bottle stopper 120 is relatively good.

[0064] The method for opening the liquid supply bottle 100 of this application is as follows: Press the operating end 173 toward the bottle stopper 120. The operating end 173 drives the connecting end 174 to move away from the bottle stopper 120, and the latch 175 on the connecting end 174 disengages from the latch 127 on the bottle stopper 120. Then, remove the outer cover 160 from the bottle stopper 120 and the inner cover 150. Remove the inner cover 150 from the insertion part 121, and the liquid supply bottle 100 is opened. The opening steps of the liquid supply bottle 100 of this application are relatively complicated, which can prevent children from opening it at will.

[0065] This application also provides an electronic atomizer, which includes an atomizing device and the aforementioned liquid supply bottle 100. The atomizing device has a liquid storage chamber inside. The liquid supply bottle 100 is connected to the atomizing device, with a connector 121 inserted into the liquid storage chamber. The liquid injection channel 122, the air exchange channel 123, and the liquid guiding medium 130 communicate with the liquid storage chamber. The electronic atomizer of this application includes the aforementioned liquid supply bottle 100 and therefore possesses all the beneficial effects of the aforementioned liquid supply bottle 100, which will not be elaborated further.

[0066] The above description is merely a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
