[0021] like Figures 1 to 5As shown in the figure, the present application provides an oil storage bottle, which includes a first storage component 100 and a second storage component 200. The first storage component 100 includes a first storage bottle 110. The interior of the first storage bottle 110 has a first accommodation space 111 for accommodating e-liquid. A connection groove 112 is provided at the bottom of the first storage bottle 110. The second storage component 200 includes a second storage bottle 210. The interior of the second storage bottle 210 has a second accommodation space 211 for accommodating flavoring agents. The second storage bottle 210 includes a first opening 212, and the first opening 212 is inserted into the connection groove 112, so that the first storage bottle 110 and the second storage bottle 210 are fixedly connected.

[0022] In a specific embodiment, the first storage component 100 is the main component for storing e-liquid. The first storage bottle 110 therein provides a dedicated storage space for e-liquid, that is, the first accommodation space 111. The size and shape of the first accommodation space 111 can be designed according to actual needs to meet the storage of e-liquid with different capacities. The connection groove 112 is provided at the central position of the bottom of the first storage bottle 110. The connection groove 112 is a cylindrical groove, and the function of the connection groove 112 is to connect with the second storage bottle 210 to realize the combination of the two storage bottles.

[0023] The second storage component 200 is the part for storing flavoring agents. The second accommodation space 211 in the second storage bottle 210 is used for storing flavoring agents. The first opening 212 is the part where the second storage bottle 210 is connected to the first storage bottle 110. By inserting the first opening 212 into the connection groove 112, the two storage bottles are fixed together to form an integral oil storage bottle. Such a design separates the storage of e-liquid and flavoring agents, keeps the two independent of each other before use, avoids accidental mixing when not in use, and is convenient for subsequent mixing operations. In summary, separating the storage of e-liquid and flavoring agents ensures the quality stability of the two before use, and avoids problems such as flavor changes or deterioration caused by premature mixing. Secondly, the fixed connection method of the two storage bottles makes the overall structure of the oil storage bottle compact, convenient for carrying and storing, and reduces the occupied space. Moreover, this combined design provides an infrastructure for subsequent mixing of e-liquid and flavoring agents, facilitating users to operate according to their own needs and enhancing the convenience and flexibility of use.

[0024] As Figure 3 and Figure 4 shown, a first limiting strip 213 is provided on the outer periphery of the first opening 212, and a second limiting strip 113 is provided on the inner wall of the connection groove 112. The first limiting strip 213 and the second limiting strip 113 are matched with each other. When the second storage bottle 210 is not in use, the first limiting strip 213 and the second limiting strip 113 are engaged with each other, so that the second storage bottle 210 cannot move relative to the first storage bottle 110.

[0025] In a specific embodiment, the first limiting strip 213 is a convex structure arranged on the outer periphery of the first opening 212 of the second storage bottle 210, and its shape and size are specially designed to cooperate with the second limiting strip 113 on the inner wall of the connecting groove 112. The second limiting strip 113 is a convex structure located on the inner wall of the connecting groove 112 of the first storage bottle 110, and forms a clamping and matching relationship with the first limiting strip 213. When the second storage bottle 210 is not in use, clamping the first limiting strip 213 with the second limiting strip 113 can effectively limit the up and down movement of the second storage bottle 210 relative to the first storage bottle 110, so as to ensure that when the oil storage bottle does not perform liquid mixing operation, the relative position between the two storage bottles remains fixed, preventing the flavoring agent from being prematurely mixed with the e-liquid due to accidental collision or shaking. This limiting structure design is simple and reliable, realizing a firm connection between the storage bottles through mechanical clamping, and at the same time facilitating the unlocking and movement of the second storage bottle 210 during subsequent mixing operations. As shown in the figure, the second storage assembly 200 further includes a first plug 220, and the first plug 220 is embedded in the first opening 212 to block the second storage bottle 210. The first plug 220 is provided with a plurality of first through holes 221, and the first through holes 221 penetrate through the first plug 220.

[0026] In a specific embodiment, the first plug 220 is a component specifically used to block the first opening 212 of the second storage bottle 210. The shape and size of the first plug 220 are adapted to the first opening 212, and can be tightly embedded in the first opening 212, thereby closing the second accommodation space 211 inside the second storage bottle 210 to prevent the flavoring agent from leaking. The first through holes 221 are holes opened on the first plug 220, and these holes penetrate through the first plug 220. Their function is to provide a channel for the outflow of the flavoring agent when the flavoring agent needs to be mixed with the e-liquid. In this embodiment, a plurality of first through holes 221 are arranged in a matrix in a uniform manner. When the second storage bottle 210 is in a normal storage state, the first plug 220 blocks the second storage bottle 210, and at this time the flavoring agent is sealed in the second accommodation space 211; while during the mixing operation, through a specific operation method, the flavoring agent can flow out through the first through holes 221 and then be mixed with the e-liquid. The existence of the first plug 220 not only ensures the tightness of the flavoring agent storage, but also provides the necessary structural support for the subsequent mixing process. Such as Figure 4As shown, the first storage bottle 110 further includes a second through-hole 114 that communicates the first accommodation space 111 with the outside. The connection groove 112 includes a limiting surface 115. The second through-hole 114 is provided on the limiting surface 115 and does not coincide with the first through-hole 221. When the first limiting strip 213 and the second limiting strip 113 are engaged, the first plug 220 abuts against the limiting surface 115. At this time, the limiting surface 115 blocks the first through-hole 221, preventing the flavoring agent in the second accommodation space 211 from flowing out through the first through-hole 221.

[0027] In a specific embodiment, the second through-hole 114 is a hole opened on the first storage bottle 110, which functions to communicate the first accommodation space 111 with the outside and provides a channel for the flavoring agent to flow into the first accommodation space 111 when mixing the flavoring agent and the e-liquid. The limiting surface 115 is the surface of the connection groove 112 close to the first accommodation space 111. The second through-hole 114 is provided on this limiting surface 115 and does not coincide with the first through-hole 221 on the first plug 220 in terms of position. When the first limiting strip 213 and the second limiting strip 113 are in the engaged state, the first plug 220 abuts against the limiting surface 115. At this time, the limiting surface 115 completely blocks the first through-hole 221, effectively preventing the flavoring agent in the second accommodation space 211 from flowing out through the first through-hole 221 and ensuring that the flavoring agent does not accidentally flow into the first accommodation space 111 to mix with the e-liquid when no mixing operation is performed. This structural design realizes precise control of the outflow of the flavoring agent by skillfully utilizing the positional relationship between the limiting surface 115 and the through-hole, ensuring the functional stability of the oil storage bottle in different usage states. As Figure 3 As shown, the first opening 212 is circular, and the first limiting strip 213 is an arc located on the outer periphery of the first opening 212. By manually rotating the second storage bottle 210, the first limiting strip 213 and the second limiting strip 113 can be separated from each other. After that, by pulling the second storage bottle 210, a gap can be generated between the first plug 220 and the limiting surface 115. If the second storage bottle 210 is inverted at this time, the flavoring agent in the second accommodation space 211 will flow into the gap through the first through-hole 221 and then flow into the first accommodation space 111 through the second through-hole 114 to mix with the e-liquid.

[0028] In a specific embodiment, the first opening 212 is designed to be circular, which facilitates the cooperation with the connection groove 112 and enables easy rotation operation. The first limiting strip 213 is arc-shaped and surrounds the outer periphery of the first opening 212. Its shape and position match those of the second limiting strip 113. In this embodiment, the first limiting strip 213 consists of two arc-shaped strips symmetrically distributed with respect to the first opening 212, and the second limiting strip 113 consists of two arc-shaped strips symmetrically distributed on the inner wall of the connection groove 112. By manually rotating the second storage bottle 210, taking advantage of the characteristics of the arc-shaped structure, the first limiting strip 213 and the second limiting strip 113 can be separated from each other, thus releasing the clamped state between them. After the clamping is released, pulling the second storage bottle 210 will create a gap between the first sealing plug 220 and the limiting surface 115. When the second storage bottle 210 is inverted, under the action of gravity, the flavoring agent in the second accommodation space 211 will flow through the first through hole 221 on the first sealing plug 220 into this gap, and then flow through the second through hole 114 on the first storage bottle 110 into the first accommodation space 111 to be mixed with the e-liquid therein. This operation method is simple and intuitive. Through manual rotation, pulling, and inversion operations, the mixing process of the flavoring agent and the e-liquid is realized, and the user can conveniently control the timing and amount of mixing. In summary, the user can achieve the mixing of the flavoring agent and the e-liquid only through simple manual operations without the need to rely on complex tools or master special skills, greatly improving the convenience of use. On the other hand, by controlling the mixing process manually, the user can flexibly control the inflow amount of the flavoring agent according to their own taste and needs, thereby precisely preparing mixed liquids with different flavors to meet personalized usage requirements. In addition, this structural design makes the use process of the oil storage bottle more interesting and interactive, enhancing the user experience.

[0029] As Figure 3 shown, a first convex strip 214 is provided on the inner wall of the second storage bottle 210 near the first opening 212, and the first sealing plug 220 is provided with a first groove 222. The first convex strip 214 matches the first groove 222, and the first convex strip 214 is embedded in the first groove 222, so that the first sealing plug 220 is fixed at the first opening 212.

[0030] In a specific embodiment, the first rib 214 is an annular convex structure provided on the inner wall of the second storage bottle 210 near the first opening 212, and the first groove 222 is an annular groove structure formed on the first plug 220. The shape and size of the first groove 222 are adapted to those of the first rib 214. When the first plug 220 is inserted into the first opening 212, the first rib 214 will accurately fit into the first groove 222. Through this cooperation mode of the rib and the groove, the first plug 220 can be effectively fixed at the first opening 212, preventing the first plug 220 from loosening or falling off during storage and use, and ensuring the sealing performance of the second storage bottle 210. This fixing method is simple and reliable, without the need for additional connecting parts or complex operations, ensuring the firm installation of the first plug 220. In this embodiment, the first plug 220 is made of silica gel material.

[0031] As Figure 4 shown, a third limiting strip 116 is further provided on the inner wall of the connecting groove 112. The third limiting strip 116 is located on the side of the second limiting strip 113 away from the limiting surface 115. When the second storage bottle 210 is pulled to the extreme position, the first limiting strip 213 abuts against the third limiting strip 116 to prevent the second storage bottle 210 from detaching from the connecting groove 112.

[0032] In a specific embodiment, the third limiting strip 116 is an annular convex structure provided on the inner wall of the connecting groove 112, and its position is on the side of the second limiting strip 113 away from the limiting surface 115. During the operation of mixing the flavoring agent and the e-liquid, when the second storage bottle 210 is pulled to a certain extent, that is, to the extreme position, the first limiting strip 213 on the second storage bottle 210 will abut against the third limiting strip 116. This abutting effect can effectively limit the further outward movement of the second storage bottle 210, thereby preventing the second storage bottle 210 from completely detaching from the connecting groove 112. The setting of the third limiting strip 116 provides a safe boundary for the movement of the second storage bottle 210. While ensuring that the user can smoothly perform the mixing operation, it ensures that the second storage bottle 210 will not detach from the connecting groove 112 due to excessive pulling, avoiding possible problems such as liquid leakage, and ensuring the integrity of the oil storage bottle structure and the safety of use.

[0033] As shown in Figure 4, the first storage bottle 110 further includes a second opening 117. A first thread 118 is provided on the outer periphery of the second opening 117. The first storage assembly 100 further includes a first protective cover 120. A second thread is provided on the inner wall of the first protective cover 120. The first thread 118 matches the second thread.

[0034] In a specific embodiment, the second opening 117 is an opening part on the first storage bottle 110. Its function is to provide an openable and closable entrance for the first storage bottle 110 to facilitate the addition of e-liquid. The first thread 118 is provided on the outer periphery of the second opening 117. The second thread on the inner wall of the first protective cap 120 matches the first thread 118 on the outer periphery of the second opening 117. By rotating the first protective cap 120 and using the thread fit, the first protective cap 120 can be tightly installed on the second opening 117, thereby protecting the second opening 117 and preventing e-liquid from leaking from the second opening 117 during storage and use. This threaded connection method is convenient to operate, has good sealing performance, and also facilitates the user to open the first protective cap 120 at any time according to needs to operate the first storage bottle 110.

[0035] As Figure 2 shown, the first storage assembly 100 further includes a second plug 130, an oil outlet pipe 131 and an oil outlet channel. The second plug 130 is embedded in the second opening 117 to block the second opening 117. The oil outlet pipe 131 is provided on the second plug 130, and the oil outlet channel runs through the oil outlet pipe 131 and the second plug 130.

[0036] In a specific embodiment, the second plug 130 is a component specifically used to block the second opening 117 of the first storage bottle 110. The shape and size of the second plug 130 are adapted to the second opening 117 and can be tightly embedded in the second opening 117 to prevent e-liquid leakage. The oil outlet pipe 131 is cylindrical and is provided at the central position of the second plug 130. The oil outlet channel runs through the oil outlet pipe 131 and the second plug 130, enabling the first accommodation space 111 to communicate with the outside, so that e-liquid can flow out of the first accommodation space 111, facilitating the user to use. The settings of the second plug 130 and the oil outlet pipe 131 improve the functions of the oil storage bottle in terms of sealing and oil outlet respectively, and enhance the reliability of the oil storage bottle. The shape of the first protective cap 120 matches the shape of the oil outlet pipe 131. When the first protective cap 120 is threadedly assembled with the first storage bottle 110, the first protective cap 120 can effectively protect the oil outlet pipe 131.

[0037] As Figure 2 and Figure 5 shown, the second storage assembly 200 further includes a second protective cap 140. The second protective cap 140 is sleeved on the first protective cap 120. The first protective cap 120 is provided with a limiting groove 121. The second protective cap 140 includes a limiting plate. When the second protective cap 140 is sleeved on the first protective cap 120, the limiting plate is embedded in the limiting groove 121 to prevent the second protective cap 140 from rotating.

[0038] In a specific embodiment, the second protective cover 140 is cylindrical. The second protective cover 140 is a structure for protecting the first protective cover 120, and its main function is to provide additional protection for the first protective cover 120 to avoid damage to the first protective cover 120 caused by external factors or affecting its normal use. The first protective cover 120 is a component in the first storage component 100 for protecting the second opening 117 and related structures. The limiting groove 121 is a rectangular groove structure opened at the top of the first protective cover 120. There are several limiting grooves 121, and several limiting grooves 121 are evenly distributed. The limiting plate is arranged inside the second protective cover 140. The limiting plate is a rectangular plate. Several limiting plates match several limiting grooves 121. When the second protective cover 140 is sleeved on the first protective cover 120, the limiting plate can accurately be embedded in the limiting groove 121. Through the cooperation of the limiting plate and the limiting groove 121, the rotation of the second protective cover 140 relative to the first protective cover 120 is effectively restricted, so that a relatively fixed positional relationship is maintained between the two protective covers. This design not only enhances the stability of the overall structure of the oil storage bottle, but also can prevent problems such as component loosening that may be caused by the rotation of the second protective cover 140 to a certain extent.

[0039] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present application by the same token.
