Technical Field
[0001] This utility model relates to the field of container technology, and more specifically, to an adjustable interface bottle bottom structure, a liquid container, and a liquid container assembly. Background Technology
[0002] Currently, containers used to hold floral water are typically glass or plastic bottles with a one-piece sealed bottom, allowing the water to be shaken or sprayed out from the top. After the floral water has diffused for a period of time, its concentration decreases, rendering it ineffective. For example, if a user uses floral water to repel mosquitoes at night, its effectiveness will significantly decline in the latter half of the night, potentially requiring the user to reapply to maintain a stable concentration. In other words, existing floral water containers do not automatically replenish the water, impacting the user experience. Utility Model Content

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.
[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0024] This utility model provides a bottle bottom structure with an adjustable interface, such as Figure 1-5 As shown, it includes a discharge nozzle 1 for connecting to the bottom of the bottle body 7, a sealing inner plug 2 for movably sealing the discharge nozzle 1, and a bottom cover 3 for driving the sealing inner plug 2 to rotate and thus movably seal the discharge nozzle 1; the bottom cover 3 is rotatably sleeved on the discharge end of the discharge nozzle 1, the bottom cover 3 is snapped into the sealing inner plug 2, and the discharge nozzle 1 is threaded into the sealing inner plug 2; the bottom cover 3 has a diffusion hole 321 for the material dripping inside it to diffuse to the external environment.
[0025] Specifically, the nozzle 1 is installed at the bottom of the bottle body 7 using existing sealing methods such as threaded connection or nesting. The bottom of the bottle body 7 has an opening for introducing the product, such as toilet water, into the nozzle 1. The upper end of the nozzle 1 is the connection end to the bottle body 7, and its lower end is the dispensing end. The bottom cover 3 is rotatably fitted onto the dispensing end of the nozzle 1. The bottom cover 3 can rotate freely around the nozzle 1 and is fitted with a sealing inner plug 2, which is driven by a snap-fit connection. When the bottom cover 3 is rotated forward, the sealing inner plug 2 slides upward to seal the nozzle 1; when the bottom cover 3 is rotated in the reverse direction, the sealing inner plug 2 slides downward and no longer seals the nozzle 1, at which point the product drips into the bottom cover 3. By adjusting the rotation angle of the bottom cover 3, the dripping speed and volume of the product can be adjusted. After the product drips into the bottom cover 3, it diffuses into the external environment through the diffuser hole 321. When the liquid is specifically toilet water, simply rotate the bottom cap 3 to the appropriate angle, and the toilet water inside the bottle 7 will drip into the bottom cap 3 at a rate of approximately 1 to 30 drops per hour, then automatically diffuse into the indoor environment, avoiding the need for users to manually refill the toilet water multiple times, thus improving the user experience. It should be noted that the sealing top cap 9 on the bottle 7 must be loosened or removed for the toilet water to drip smoothly.
[0026] Furthermore, the discharge nozzle 1 includes a base plate 11. The connecting end of the base plate 11 is provided with a sealing outer ring 12 and a sealing inner ring 13 for sealing the bottom of the bottle body 7. The discharge end of the base plate 11 is provided with a discharge pipe 14. The discharge end of the base plate 11 and outside the discharge pipe 14 is provided with a sliding ring 15 for slidingly fitting the sealing inner plug 2. The discharge end of the base plate 11 and outside the sliding ring 15 is provided with a snap-fit ring 16 for fitting with the bottom cover 3. The base plate 11, the sealing outer ring 12, the sealing inner ring 13, the discharge pipe 14, the sliding ring 15 and the snap-fit ring 16 are integrally formed. The sealing inner plug 2 is threadedly connected to the discharge pipe 14 and movably blocks the discharge pipe 14. The sealing inner plug 2 fits the discharge pipe 14, and the bottom cover 3 is rotatably fitted with the snap-fit ring 16.
[0027] Furthermore, the discharge pipe 14 has a material channel 141 inside, and the sealing inner plug 2 has a conical protrusion 21 inside for movably blocking the material channel 141.
[0028] Furthermore, the conical boss 21 is located in the middle of the sealing inner plug 2, and several discharge holes 211 are provided on its bottom edge.
[0029] like Figure 3-5 As shown, the entire nozzle 1 is integrally injection molded from plastic. The bottom of the bottle body 7 is located between the sealing outer ring 12 and the sealing inner ring 13. The inner wall of the sealing outer ring 12 has internal threads, and the outer wall of the bottom of the bottle body 7 has external threads. The internal and external threads are matched so that the nozzle 1 is installed at the bottom of the bottle body 7. The sliding ring 15 mainly serves to limit the sealing inner plug 2. The bottom cover 3 is rotatably fitted and snapped onto the snap ring 16 through the limiting structure. The discharge tube 14 is cylindrical in shape, with a material channel 141 inside, and external threads adapted to the sealing inner plug 2 are opened on its outer wall. The sealing inner plug 2 is cylindrical in shape, with a conical boss 21 integrally formed in the middle of its interior, used to seal the lower end of the discharge tube 14, thereby preventing the material from dripping into the bottom cover 3 from inside the material channel 141 through the three discharge holes 211. In this embodiment, the outer sealing ring 12 and the inner sealing ring 13 seal the bottle body 7 by clamping together, which provides a better sealing effect compared to a design with only the outer sealing ring 12. To achieve an even better sealing effect, a sealing ring 8 can also be installed in the gap between the outer sealing ring 12 and the inner sealing ring 13.
[0030] Furthermore, the bottom cover 3 includes a connecting ring 31, a rotating ring 32 for driving its rotation is provided on the outer side of the connecting ring 31, and a sealing drive ring 33 for driving the inner sealing plug 2 to rotate and thus move to block the discharge pipe 14 is provided on the inner side of the connecting ring 31; the connecting ring 31, the rotating ring 32, and the sealing drive ring 33 are integrally formed; a diffusion hole 321 is opened on the rotating ring 32, and a sealing bottom cover 343 is provided at the bottom of the rotating ring 32.
[0031] Furthermore, a diffusion cotton 4 for receiving the material is placed inside the bottom cover 3.
[0032] like Figure 3-5 As shown, the connecting ring 31 is a horizontally arranged annular body, with a sealing drive ring 33 integrally formed on its inner side and a rotating ring 32 integrally formed on its outer side. The inner wall of the rotating ring 32 has a first snap-fit groove (not shown in the attached figure) that matches the snap-fit protrusion on the outer wall of the snap-fit ring 16. The sealing drive ring 33 has three equally spaced second snap-fit grooves 331 that match the snap-fit blocks 22 on the outer wall of the sealing inner plug 2. Inserting the snap-fit blocks 22 into the second snap-fit grooves 331 allows the sealing inner plug 2 to rotate with the bottom cover 3. The rotating ring 32 has multiple diffusion holes 321, forming diffusion windows. The bottom cover 343 is sealed and nested at the bottom of the rotating ring 32 by an interference fit and serves to receive the diffusion cotton 4. The diffusion cotton 4 can highly absorb the material, slowing down the evaporation rate of the material, thereby allowing the material to diffuse smoothly and for a long time.
[0033] Furthermore, the bottom of the sealing inner plug 2 is provided with a guide cotton core 5 for guiding the material from the discharge hole 211 to the diffusion cotton 4.
[0034] like Figure 3 As shown, the guide cotton core 5 abuts against the discharge hole 211, and the lower end abuts against the diffusion cotton 4. Utilizing its capillary action, it continuously transfers volatile substances such as floral water to the diffusion cotton 4 for evaporation.
[0035] This utility model also provides a liquid container, which includes a bottle body 7 with an opening at the bottom and the aforementioned adjustable interface bottom structure; the bottom of the bottle body 7 is detachably and sealed to the discharge nozzle 1, such as a threaded sealing connection or a nested sealing connection.
[0036] This utility model also provides a liquid container assembly, which includes the aforementioned liquid container and a sealing top cover 9. The sealing top cover 9 is connected to the bottle body 7 in the liquid container in a conventional manner. This liquid container assembly also includes a replacement bottom cover 6 for replacing the adjustable interface bottom structure (e.g., Figure 6 As shown), the replacement bottom cap 6 is sealed to the bottom of the bottle body 7, specifically by a threaded seal. The replacement bottom cap 6 enables the liquid container to achieve the technical effect of serving two purposes in one bottle.
[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
