[0044] When replacing the liquid storage bottle of existing products, there is a problem that the bottle mouth is not easy to open.

[0045] In this application, a stress concentration part is provided in the nozzle structure provided at the bottle mouth of the bottle body. By utilizing the characteristic that the connection strength of the stress concentration part is small, the quick opening of the nozzle is realized, and thus the convenient opening of the bottle mouth is achieved.

[0046] Please refer to Figures 1 to 2 , Figure 1 is a cross-sectional view of a liquid storage bottle in an embodiment, Figure 2 is a schematic diagram of a liquid storage bottle in an embodiment.

[0047] As Figures 1 to 2 shown, an embodiment of this application provides a liquid storage bottle, including a bottle body 1 and a nozzle 12; the bottle body 1 has a bottle mouth 2 communicating with the inside and outside, and the nozzle 12 covers the bottle mouth 2; the nozzle 12 includes a connection cap 121 and a functional structure 122, the functional structure 122 is connected to the connection cap 121, and the connection cap 121 is connected to the bottle mouth 2; the connection part between the functional structure 122 and the connection cap 121 is a stress concentration part 3, so that the functional structure 122 is configured to be removable under the action of an external force.

[0048] The bottle body 1 is hollow inside for storing fluids. The bottle body 1 is provided with a bottle mouth 2. After the bottle mouth 2 communicates with the inside and outside of the bottle body 1, fluids can enter and exit the bottle body 1 from the bottle mouth 2, and the outer end of the bottle mouth 2 is the liquid outlet; the bottle body 1 can be an injection molded part.

[0049] The bottle mouth 12, which is adapted to the bottle opening 2 and is used to seal the bottle opening 2; it includes a connecting cap 121 and a functional structure 122. The functional structure 122 is connected to the connecting cap 121, and the connecting cap 121 is connected to the bottle opening 2. In this embodiment, the middle part of the connecting cap 121 has a connecting channel. One end of the connecting cap 121 is connected to the bottle opening 2. At this time, the connecting channel is communicated with the inside of the bottle body 1, and the functional structure 122 is connected to the other end of the connecting cap 121 to seal the bottle opening 2. Among them, the connection method between the connecting cap 121 and the bottle opening 2 includes but is not limited to interference fit, threaded fit, ultrasonic welding process connection, etc. In addition, the functional structure 122 can be connected to the outer wall or the inner wall of the bottle opening 2, and no limitation is made here.

[0050] The stress concentration part 3 is arranged at the connection part between the functional structure 122 and the connecting cap 121; in one embodiment, the stress concentration part 3 can be a thin wall. It can be understood that the stress concentration part 3 is thinner than the connecting cap 121 and the functional structure 122 at this position, so the connection strength at the stress concentration part 3 is smaller. When subjected to an external force, the stress concentration part 3 is more likely to break, so that the functional structure 122 is separated from the connecting cap 121. In one embodiment, the functional structure 122 is connected to one end face of the connecting cap 121. When the functional structure 122 is separated from the connecting cap 121, an opening can be formed at this end face.

[0051] In this embodiment, when it is necessary to open the bottle opening 2, an external force is applied to the functional structure 122. After the stress concentration part 3 breaks, the functional structure 122 can be separated from the connecting cap 121, thereby realizing the rapid opening of the bottle opening 2.

[0052] In one embodiment, see Figure 1 , the liquid storage bottle further includes a liquid guiding member 4; the liquid guiding member 4 is arranged at the bottle opening 2 and blocks the bottle opening 2; the liquid guiding member 4 is a porous material.

[0053] The liquid guiding member 4, which is adapted to the bottle opening 2, is arranged in the bottle opening 2, and its arrangement methods include but are not limited to the liquid guiding member 4 being tightly plugged in the bottle opening 2 or adhesively bonded in the bottle opening 2. The significance of arranging the liquid guiding member 4 is that: after the bottle mouth 12 is opened, if the bottle body 1 is inverted and installed at this time (that is, the liquid outlet of the bottle opening is downward) or tilted, at this time, the fluid in the bottle body 1 flows downward and towards the liquid outlet, and the liquid guiding member 4 can effectively block the fluid to reduce the flow rate, avoid the rapid outflow of the fluid, so enough installation time is reserved for the bottle body 1 before the fluid flows out of the bottle opening 2, prevent the fluid from spilling, ensure the clean and tidy installation operation environment, and also avoid waste; at the same time, the liquid guiding member 4 can control the flow rate of the fluid flowing out of the bottle opening 2, so as to realize uniform and quantitative liquid discharge.

[0054] In this embodiment, the liquid guiding member 4 can be a liquid guiding cotton, a liquid guiding foam or other porous materials with permeability, and will not be listed one by one here.

[0055] In one embodiment, at least one ventilation channel 41 is provided in the liquid guide member 4, and the ventilation channel 41 penetrates the liquid guide member 4 along the depth direction of the bottle body 1.

[0056] Ventilation channel 41. In this embodiment, the number of ventilation channels 41 can be one or more, and there is no limitation here. The ventilation channel 41 communicates with both ends of the liquid guide member 4. After the functional structure 122 is opened, the air outside the bottle mouth 2 can enter the bottle body 1 through the ventilation channel 41, thereby achieving the effect of balancing the pressure inside and outside the bottle body 1 and avoiding the problem that the fluid cannot flow out to the bottle mouth 2 when the bottle body 1 is inverted due to the formation of negative pressure inside the bottle; thus, in this embodiment, the ventilation channel 41 penetrates the liquid guide member 4 along the depth direction (i.e., the radial direction) of the bottle mouth 2.

[0057] Among them, the aperture diameter of the ventilation channel 41 is about φ0.5 - 1.5 mm, and it can be selected within this range, such as 0.5 mm, 0.7 mm, 0.9 mm, 1.1 mm, 1.3 mm, etc. which can be selected but not limited to.

[0058] In one embodiment, a limiting portion 5 is provided inside the bottle mouth 2, and one end of the liquid guide member 4 close to the inner cavity of the bottle body 1 abuts against the limiting portion 5.

[0059] Limiting portion 5 is provided on the inner wall of the bottle mouth 2. The above-mentioned liquid guide member 4 is arranged in the bottle mouth 2. To prevent the liquid guide member 4 from falling into the deep part of the bottle body 1, one end of the liquid guide member 4 inside the bottle mouth 2 away from the liquid outlet abuts against the limiting portion 5. In this way, the liquid guide member 4 is limited by the limiting portion 5 and thus will not fall into the bottle body 1.

[0060] In this embodiment, the limiting portion 5 can be an annular protrusion or protrusions of various shapes. Additionally, after the liquid guide member 4 is installed in the bottle mouth 2, the limiting portion 5 can also be located at any position on the circumferential side of the liquid guide member 4. In this way, the limiting portion 5 squeezes the side wall of the liquid guide member 4 towards the middle to achieve the limitation of the liquid guide member 4.

[0061] Figure 3 It is another structural schematic diagram of the liquid storage bottle in one embodiment; Figure 5 For Figure 3 The cross-sectional view of the liquid storage bottle; Figure 6 For Figure 5 The enlarged view of part A in

[0062] In one embodiment, the stress concentration portion 3 includes a groove 31 provided circumferentially around the functional structure 122.

[0063] Stress concentration portion 3, combined with Figure 6, As known from the above, the functional structure 122 is arranged at the end of the connection channel of the connection cap 121 away from the bottle body 1, that is, the outer edge of the functional structure 122 is hermetically connected to the rim at one end of the connection channel, and this is the sealing edge of the functional structure 122. A groove 31 is arranged around the sealing edge, and the groove 31 forms a stress concentration part 3, so the connection strength at the position of the stress concentration part 3 is relatively small; it should be noted that in this embodiment, the groove 31 does not penetrate the sealing edge, and this setting is to prevent the fluid in the bottle body 1 from leaking out through the groove 31.

[0064] For example, the cross-section of the groove 31 in the width direction is V-shaped. The stress concentration at the tip of the V-shaped groove 31 reduces the connection strength at this place. Under the action of external force, the V-shaped groove 31 is more likely to break, further reducing the opening difficulty of the functional structure 122. In addition, the cross-sectional shape of the groove 31 in the width direction can be set according to different requirements for connection strength, such as an arc shape with stronger connection strength, etc., and will not be listed one by one here. In this embodiment, the groove 31 is arranged on the outer side surface of the functional structure 122 facing away from the bottle mouth, so it is more convenient for the manufacturing and forming of the groove 31; of course, according to different design needs, the groove 31 can be arranged on the inner side surface of the functional structure 122 close to the bottle mouth.

[0065] In addition, there can be multiple grooves 31, and the multiple grooves 31 are designed at intervals along the sealing edge. In this way, it can not only ensure the connection strength between the connection cap 121 and the functional structure 122, but also ensure the quick separation of the connection cap 121 and the functional structure 122.

[0066] In one embodiment, the connection cap 121 is inserted through the bottle mouth 2 and is in close fit with the inner wall of the bottle mouth 2; a closing part 1211 is arranged on the side wall of the connection cap 121 facing away from the bottle mouth 2, and the closing part 1211 abuts against the end of the bottle mouth 2.

[0067] The closing part 1211 is arranged on the outer side wall of the connection cap 121. In this embodiment, the closing part 1211 is a convex ring, and preferably, the convex ring is arranged at the middle position of the outer side wall of the connection cap 121; in this way, one end of the connection cap 121 is inserted into the bottle mouth, the convex ring abuts against the bottle mouth, and the other end of the connection cap 121 is located outside the bottle mouth 2; at this time, the convex ring is hermetically connected to the rim installed on the bottle mouth 2 by ultrasonic waves. The ultrasonic connection method makes the connection strength between the connection cap 121 and the bottle mouth higher and the sealing performance stronger.

[0068] In addition, in the present embodiment, the liquid guiding member 4 is arranged in the connecting channel of the connecting cap 121; and the end of the liquid guiding member 4 away from the limiting portion 5 is retracted in the connecting channel. It can be understood that a step with a height difference is formed from the end of the liquid guiding member 4 away from the limiting portion 5 to the outer edge of the connecting channel. The height of this step is 0.5mm-1mm. This value can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm or 1mm, which are not listed here one by one.

[0069] In one embodiment, the functional structure 122 includes a gripping portion located outside the bottle body 1 ; the gripping portion is configured to drive the functional structure 122 to disconnect from the connecting cap 121 at the stress concentration portion 3 under the action of an external force.

[0070] The gripping portion is connected to the connecting cap 121. The gripping portion can be a protruding structure of any shape. The protruding structure serves as an external force receptor, which facilitates the application of external force.

[0071] Figure 4 for Figure 3 Exploded view of the liquid storage bottle.

[0072] In one embodiment, combining Figures 3 to 5 The gripping portion includes a flat force-bearing member 1223 vertically arranged relative to the connecting cap 121. It is understandable that the number of the force-bearing members 1223 can be one or more, which is not limited here; the force-bearing planes 12231 on a force-bearing member 1223 can be one or more, which is not limited here. Figure 3 In this embodiment, when external force is applied to the force-bearing member 1223, the hand can be in contact with the force-bearing plane 12231, thereby increasing the gripping force points and making it easier to apply external force. In other cases, when using tools such as clamps to pry the gripping member, the force-bearing plane 12231 can be used as a clamping surface, which is convenient for gripping the tool.

[0073] In one embodiment, the functional structure 122 also includes an oil filling tube 1222 and a sealing portion 1221; the sealing portion 1221 is connected to and covers the end of the connecting cap 121 that faces away from the bottle body 1; the oil filling tube 1222 is connected to the sealing portion 1221 and communicates with the connecting cap 121; the force-bearing members 1223 are symmetrically arranged on both sides of the oil filling tube 1222 and connected to the sealing portion 1221.

[0074] The sealing portion 1221 is disposed at the outer end of the connection cap 121 (i.e., the end of the connection cap 121 outside the bottle mouth 2), thereby closing the outer end of the connection channel. In combination with the above, the sealing edge refers to the outer edge of the sealing portion 1221. For example, the sealing portion 1221 is a sealing sheet.

[0075] The oil filling tube 1222, in this embodiment, is protrudingly arranged outside the sealing sheet, and is in the shape of a truncated cone, and the outer diameter of the truncated cone-shaped oil filling tube 1222 gradually decreases in the direction away from the bottle mouth 2. In other cases, the oil filling tube 1222 may be in the shape of a square convex block or a column, etc., which are not listed here one by one; in addition, the middle part of the oil filling tube 1222 is a cavity or a channel, and the cavity or the channel is connected to the connecting cap 121, and the cavity or the channel makes the wall thickness of the oil filling tube 1222 uniform, avoiding defects such as injection shrinkage.

[0076] The above-mentioned oil filling tube 1222 is provided to increase the force point of the external force applied to the sealing sheet. After grasping the oil filling tube 1222, the hand tilts and pulls it to one side, so that the sealing sheet and the connecting cap 121 can be separated more conveniently, saving time and effort.

[0077] The force bearing member 1223 is arranged on the side of the sealing portion 1221 away from the bottle evaluation body 1. Figure 5 In this embodiment, taking two force-bearing members 1223 as an example, the two force-bearing members 1223 are symmetrically arranged on both sides of the oil filling pipe.

[0078] Taking three force-bearing members 1223 as an example, the three force-bearing members 1223 are evenly spaced and arranged on the circumference of the oil filling pipe 1222 .

[0079] Figure 3 As shown in the figure, the force-bearing member 1223 is a right-angled triangular prism, one right-angled side of the right-angled triangular prism is connected to the side wall of the oil filling pipe 1222, and the other right-angled side is connected to the outer side of the sealing plate, and the two triangular sides of the right-angled triangular prism are the force-bearing planes 12231; the right-angled triangular prism forms a tripod support for the oil filling pipe 1222, thereby improving the stability of the connection between the oil filling pipe 1222 and the sealing plate.

[0080] In one embodiment, the functional structure 122 also includes an oil filling tube 1222 and a sealing portion 1221; the sealing portion 1221 is connected to and covers the end of the connecting cap 121 that faces away from the bottle body 1, the oil filling tube 1222 is connected to the sealing portion 1221 and communicates with the connecting cap 121, and a liquid filling port is provided at the end of the oil filling tube 1222 that faces away from the bottle body 1; the ventilation channel 41 penetrates the middle part of the liquid guide 4 along the radial direction of the bottle mouth 2; and the ventilation channel 41 is communicated with the oil filling tube 1222.

[0081] The configuration of the sealing portion 1221 and the oil filling pipe 1222 in this embodiment can refer to the above-mentioned embodiment, and will not be repeated here; the difference is that the outer end of the oil filling pipe 1222 is provided with a liquid filling port, which is specifically manifested as follows: Figure 1 and Figure 5As shown, a middle through-hole 13 is formed by surrounding within the above-mentioned oil injection pipe 1222. The middle through-hole 13 is arranged along the extending direction of the oil injection pipe 1222. In particular, one end of the middle through-hole 13 penetrates through the sealing part 1221 and communicates with the bottle mouth 2, and the other end is located on the outer wall of the oil injection pipe 1222 to form a liquid injection port. In this way, the middle through-hole 13 is communicated with the air exchange channel 41. The function of the middle through-hole 13 is that through it, oil can be directly injected into the bottle body 1 or directly drained outwards.

[0082] The above-mentioned liquid storage bottle is used to supply atomization matrix for various atomizers 11. Therefore, the specified fluid above can be the atomization matrix, and the liquid storage bottle and the atomizer 11 form an atomization system; correspondingly, the thickness of the stress concentration part 3 is less than the thickness of the sealing part 1221.

[0083] Figure 7 It is an exploded view of the atomization system in an embodiment.

[0084] Commonly, after the functional structure 122 of the bottle nozzle 12 at the bottle mouth 2 is removed in the above manner, the outer end of the connection channel of the connection cap 121 is opened at this time, so the bottle mouth 2 is also in an open state. The two ends of the external connecting pipe are respectively connected to the bottle body 1 and the atomizer 11, and the atomization matrix is transmitted to the atomizer by pumping, thereby realizing the liquid supply of the liquid storage bottle to the atomizer 11.

[0085] In addition, as can be known from the above, refer to Figure 7 , when the liquid guiding member 4 is arranged at the bottle mouth 2, the atomizer 11 is correspondingly provided with an upward liquid inlet. After the bottle mouth 2 of the bottle body 1 is sleeved downward into the liquid inlet, the atomization matrix in the bottle body 1 can flow into the atomizer under the action of gravity for atomization; the liquid guiding member 4 at the bottle mouth 2 effectively intercepts and decelerates the downward flowing atomization matrix, physically controls the flow rate of the atomization matrix. Generally speaking, the atomization matrix can flow out directly and controllably through the action of gravity, without additionally setting a pumping component for pumping the atomization matrix, which simplifies the structure of the atomizer; and the liquid guiding member 4 effectively prevents the internal atomization matrix from pouring out when the bottle body 1 is installed upside down, provides a clean working space for the installation operation, and also avoids the waste of the atomization matrix. In this solution, the atomizer 11 can be provided with an installation position for installing the liquid storage bottle. After the bottle mouth 2 of the liquid storage bottle is installed at the liquid inlet, the liquid storage bottle is located in the installation position at this time. Then, a decorative cover 14 is buckled outside the liquid storage bottle and finally connected to the atomizer 11, thereby closing the installation position. The outer wall of the decorative cover 14 is aligned with the outer circumference of the atomizer 11, so that the decorative cover 14 and the atomizer 11 form a visual integration, improving the overall aesthetic feeling.

[0086] In addition, to improve the connection strength between the bottle mouth and the liquid inlet, an external thread is provided on the outer wall of the bottle mouth 2, and an internal thread is provided on the inner wall of the liquid inlet. The internal and external threads realize the reliable fixation of the bottle mouth.

[0087] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model pertains, based on the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
