Description

Technical Field

[0001] This utility model relates to the field of liquid filling technology for cigarette holders, and in particular to a device for filling cigarette holders with liquid. Background Technology

[0002] Existing devices for filling cigarette holders with liquid typically employ a split design, consisting of a liquid-containing bottle and a separately mounted protective cap. During use, the user must manually remove the protective cap to expose the liquid dispensing tube, and then insert the cigarette holder into the tube to fill the liquid. This type of design has the following significant drawbacks:

[0003] 1. Operational redundancy: Each infusion requires a complete procedure of "opening the cap - aligning the cannula - infusion - resetting the cap," which is cumbersome and affects efficiency. Especially for high-frequency users, repeated disassembly and reassembly of the cap can easily lead to cap loss or seal failure.

[0004] 2. Insufficient sealing reliability: The fitting accuracy between the traditional detachable cap and the bottle mouth depends on the machining tolerance. After long-term use, the cap is prone to loosening, making it difficult to connect the cap to the device.

[0005] This utility model is based on the above-mentioned circumstances. Utility Model Content

[0006] This invention overcomes the shortcomings of the prior art and provides a device for adding liquid to a cigarette holder.

[0007] This utility model is achieved through the following technical solution:

[0008] A device for adding liquid to a cigarette holder includes a base with an open upper cavity. A liquid bottle is placed inside the cavity. The liquid bottle includes a bottle body for holding the liquid and a pump connected to the upper end of the bottle body for pumping out the liquid. The pump includes a pressing cap, and one side of the pressing cap has a liquid outlet tube for inserting into the cigarette holder. The pump also includes a pump body for discharging the liquid from the bottle body through the liquid outlet tube to the cigarette holder. A rotating tube for covering the liquid outlet tube is rotatably connected to the upper part of the base. A guide structure is provided between the liquid bottle and the base, which pushes the liquid bottle upward when rotated, causing the pressing cap to extend from the upper end of the rotating tube or move downward, causing the pressing cap to retract into the rotating tube. A drive structure is provided between the liquid bottle and the rotating tube, which drives the liquid bottle to rotate when the rotating tube is rotated.

[0009] As described above, a device for adding liquid to a cigarette holder includes a guide structure comprising a guide groove disposed on the side wall of the placement cavity and a slider fixedly connected to the outer wall of the liquid bottle and extending into the guide groove and sliding along the guide groove.

[0010] As described above, in a device for adding liquid to a cigarette holder, the upper end of the base is provided with a notch that communicates with a guide groove so that the slider can slide into the guide groove.

[0011] As described above, in a device for adding liquid to a cigarette holder, the base is further provided with a stop that can extend into a notch to restrict the slider from exiting the notch, and the stop has a certain degree of elasticity.

[0012] As described above, in a device for adding liquid to a cigarette holder, the pressing cap is provided with a plug that can extend into the liquid outlet of the pump body to reduce the amount of liquid pumped at a time.

[0013] As described above, in a device for adding liquid to a cigarette holder, the driving structure includes a guide groove provided on the inner wall of a rotating tube and extending along the length of the rotating tube, and the slider extends into the guide groove.

[0014] As described above, a device for adding liquid to a cigarette holder includes a base comprising an outer shell and an inner tube connected to the outer shell. The outer shell has a cavity for inserting the inner tube, the cavity being the inner hole of the inner tube, and a guide structure disposed on the inner tube.

[0015] As described above, in a device for adding liquid to a cigarette holder, a first limiting structure is provided between the outer casing and the inner tube to prevent the inner tube from dislodging from the insertion cavity.

[0016] As described above, in a device for adding liquid to a cigarette holder, the inner tube and the rotating tube are provided with a locking structure that engages the two to prevent the rotating tube from disengaging from the inner tube.

[0017] As described above, in a device for adding liquid to a cigarette holder, the pressing cap is provided with an insertion groove for inserting the cigarette holder, and the liquid outlet tube is disposed in the insertion groove.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] This product uses a linkage design between the rotating tube and the guide structure to control the lifting of the pressing cap to expose the liquid inlet tube during rotation operation; after use, simply rotate the rotating tube in the opposite direction to make the pressing cap retract into the rotating tube, which is very convenient and quick to operate. Moreover, the cap does not have a separate design, so there is no problem of repeatedly disassembling and assembling the cap, which could lead to the cap being lost or easily falling off due to insecure installation.

[0020] The rotating tube and the pressing cap form a nested closed structure. When not in use, the pressing cap retracts completely into the rotating tube, preventing accidental pressing. Furthermore, even if the device is accidentally dropped, the cover will not spring off.

[0021] The press cap is equipped with a plug that can extend into the liquid outlet of the pump body to reduce the amount of liquid pumped at one time, thereby preventing too much oil from being pumped out with each press and resulting in an overly irritating taste, thus improving the user experience.

[0029] The present invention will be further described below with reference to the accompanying drawings:

[0030] like Figures 1 to 6 The device shown is for adding liquid to a cigarette holder, including a base 1. The base 1 has an open upper cavity 2, and a liquid bottle 3 is placed inside the cavity 2. The liquid bottle 3 includes a bottle body 31 for holding liquid and a pump 32 connected to the upper end of the bottle body 31 for pumping out the liquid from the bottle body 31. The pump 32 includes a pressing cap 321, and one side of the pressing cap 321 has a liquid outlet tube 322 for inserting into the cigarette holder. The pump 32 also includes a pump to dispense the liquid from the bottle body 31. The liquid is discharged from the outlet tube 322 to the pump body 323 of the cigarette holder. The upper part of the base 1 is also rotatably connected to a rotating tube 4 for covering the outlet tube 322. A guide structure 5 is provided between the liquid bottle 3 and the base 1, which pushes the liquid bottle 3 to move upward when the liquid bottle 3 is rotated, so that the pressing cap 321 extends out from the upper end of the rotating tube 4 or moves downward to retract the pressing cap 321 into the rotating tube 4. A driving structure 6 is provided between the liquid bottle 3 and the rotating tube 4, which can drive the liquid bottle 3 to rotate when the rotating tube 4 is rotated.

[0031] This product utilizes a linkage design between the rotating tube 4 and the guide structure 5 to control the raising and lowering of the pressing cap 321 to expose the dispensing tube 322 during rotational operation. After use, simply rotating the rotating tube 4 in the opposite direction will retract the pressing cap 321 back into the rotating tube 4. Operation is very convenient and quick. Furthermore, the absence of a separate cap design eliminates the risk of cap loss or loose cap detachment due to repeated disassembly and reassembly. The rotating tube 4 and the pressing cap 321 form a nested closed structure. When not in use, the pressing cap 321 is completely retracted into the rotating tube 4, preventing accidental pressing. Additionally, even if the device is accidentally dropped, the cap will not spring off.

[0032] In one embodiment, the pump body 323 described above is similar in structure and principle to the pump body of the press pump of the spray bottle on the market, and will not be described in detail here.

[0033] In one embodiment, the guide structure 5 includes a guide groove 51 provided on the side wall of the placement cavity 2 and a slider 52 fixedly connected to the outer wall of the liquid bottle 3 and extending into the guide groove 51 and sliding along the guide groove 51. Further, two centrally symmetrical guide grooves 51 can be provided on the base 1, and two sliders 52 can be symmetrically arranged on both sides of the liquid bottle 3, thereby making the sliding of the liquid bottle 3 more stable and smooth.

[0034] Furthermore, the upper and lower ends of the guide groove 51 are provided with smooth grooves 511 to facilitate the stopping of the slider 52.

[0035] Furthermore, the upper end of the base 1 is provided with a notch 53 that communicates with the guide groove 51, thereby allowing the slider 52 to slide into the guide groove 51. This facilitates the insertion of the liquid bottle 3 onto the base 1.

[0036] Furthermore, the base 1 is also provided with a stop 54 that can extend into the notch 53 to restrict the slider 52 from exiting the notch 53. The stop 54 has a certain elasticity. When the slider 52 slides in, the elastic deformation of the stop 54 allows the slider to slide in smoothly. After the slider 52 slides in, the stop 54 returns to its original position, restricting the slider 52 from sliding out.

[0037] In one embodiment, the pressing cap 321 is provided with a plug 300 that can extend into the liquid outlet of the pump body 323 to reduce the amount of liquid pumped at one time, thereby preventing too much oil from being dispensed with each press and resulting in an overly irritating taste, thus improving the user experience.

[0038] In one embodiment, the slider 52 and the bottle body 31 are separate structures, with a bottle sleeve fitted onto the bottle body 31. The slider 52 and the bottle sleeve are integrally formed, and the bottle sleeve and the bottle body 31 are interference-fitted, so that the bottle sleeve and the bottle body 31 will not rotate relative to each other. Of course, the slider 52 can also be integrally formed with the bottle body 31.

[0039] In one embodiment, the driving structure 6 includes a guide groove provided on the inner wall of the rotating tube 4 and extending along the length of the rotating tube 4, and the slider 52 extends into the guide groove. In addition to guiding the sliding of the slider 52, the guide groove also pushes the slider 52 when the rotating tube 4 is rotated, so that the liquid bottle 3 follows the rotation of the rotating tube 4 and slides along the guide groove 51.

[0040] In one embodiment, the rotating tube 4 is further provided with a limiting ring 40 to limit the sliding distance of the bottle body 31.

[0041] In one embodiment, the base 1 includes an outer shell 11 and an inner tube 12 connected to the outer shell 11. The outer shell 11 has a cavity 111 for inserting the inner tube 12, the placement cavity 2 is the inner hole of the inner tube 12, and the guide structure 5 is provided on the inner tube 12. Specifically, the outer shell 11 and the inner tube 12 are interference-fitted to prevent relative rotation, or a second limiting structure is provided between the outer shell 11 and the inner tube 12 to restrict relative rotation between the inner tube 12 and the outer shell 11. The second limiting structure can be a matching locking block and a locking groove. The outer shell 11 and the inner tube 12 are separately arranged, thereby reducing the difficulty of manufacturing and processing, improving production efficiency and product yield.

[0042] In one embodiment, a first limiting structure 7 is provided between the outer shell 11 and the inner tube 12 to prevent the inner tube 12 from disengaging from the insertion cavity 111. Specifically, the first limiting structure 7 may be a first snap-fit ​​groove 110 provided on the wall of the insertion cavity 111 and a first snap-fit ​​block 121 provided on the outer wall of the inner tube 12. Further, the lower part of the first snap-fit ​​block 121 is provided with an inclined surface for easy installation.

[0043] In one embodiment, an engaging structure 8 is provided between the inner tube 12 and the rotating tube 4 to engage them and prevent the rotating tube 4 from disengaging from the inner tube 12. Specifically, the engaging structure 8 includes a second engaging groove 81 on the outer wall of the inner tube 12 and a second engaging block 82 on the inner hole of the rotating tube 4. The second engaging block 82 is clearance-fitted with the second engaging groove 81, thereby allowing the rotating tube 4 to rotate relative to the inner tube 12.

[0044] In one embodiment, the pressing cap 321 is provided with an insertion groove 324 for inserting a cigarette holder, and the liquid outlet tube 322 is disposed in the insertion groove 324. The pressing cap 321 is connected to the pump body 323 by sleeve, snap-fit, threaded connection or other connection methods.
