Description

A universal bottle neck adapter Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, specifically to a universal bottle neck adapter. Background Technology

[0002] A small water pump is a portable, lightweight pumping device mainly used for small-scale water extraction and transportation. It has a wide range of functions and applications, and is suitable for various scenarios such as home use, indoor potted plants, and indoor ornamental fish farming.

[0003] As people's requirements for drinking water quality become increasingly stringent, bottled water, due to its cleanliness and hygiene, has become a common part of people's lives and work. However, because bottled water dispensers are difficult to clean, more and more people prefer to install dedicated water pumps directly on their bottles. However, since the capacity and diameter of the water bottles used by different manufacturers vary (typically, the capacity and diameter of water bottles range widely, from 200ml to 20L; and the diameter ranges from 15mm to 60mm), while the size of the water pumps is fixed, the water pumps cannot be adapted to all water bottles.

[0004] To address this problem, various water pumps have been designed. Patent document CN212661643U discloses a flexible water pump fixing structure, including a mounting base and a retainer connected to the mounting base. The retainer has a mating cavity for connecting to a water bucket. The retainer includes an elastic part that can elastically deform to connect with the water bucket. The mounting base has an outlet communicating with the water bucket's outlet end. In this design, the retainer and mounting base are detachably connected, and the retainer has a certain degree of deformation, connecting to the water bucket through deformation to accommodate water buckets of different sizes. This invention adapts to different sizes of water buckets through deformation, making it highly adaptable and easy to install. However, since the retainer needs to be installed on the water bucket to support the mounting base and water pump, the retainer needs to have a certain structural strength and cannot be made of a material with very high elasticity. Therefore, its radial shrinkage cannot be large, making this design unsuitable for water buckets with large span diameters.

[0005] Therefore, it is necessary to design a connector that can be used with different bottle openings to achieve a quick and reliable connection between the water pump and water buckets or bottles of different diameters. Technical issues

[0006] The present invention aims to solve the technical problem that water pumps cannot be adapted to water buckets of various diameters. Technical solutions

[0007] To solve the above-mentioned technical problems, this utility model provides a universal bottle neck adapter, which includes a protective component, a soft rubber component, and a bottom cover. The bottom cover is ultrasonically welded to the bottom of the protective component, the soft rubber component is sandwiched between the protective component and the bottom cover, and the surface of the soft rubber component is snapped onto the bottle neck. The protective component, the soft rubber component, and the bottom cover cooperate with each other to realize the installation and conversion of bottle neck diameters of different models.

[0008] Preferably, the protective component includes a housing, a retaining ring, a through slot, a retaining slot, and a protrusion.

[0009] Preferably, the outer shell and the fixing ring are integrally formed, the fixing ring is installed on the top of the outer shell, the through slot is opened at the center of the top of the outer shell and located inside the fixing ring, the slot is opened around the bottom of the outer shell, and the protrusion is set at the bottom of the outer shell and located at the outer end of the slot.

[0010] Preferably, the soft rubber component includes a soft rubber body, dividing grooves, and holes. The dividing grooves are arranged in a ring array at the bottom of the soft rubber body. A sheet-like triangular block is formed between two adjacent dividing grooves to cooperate with the bottle mouth. Multiple sheet-like triangular blocks are folded inward and snapped onto the bottle mouth. The holes are located at the top of the sheet-like triangular blocks and at the center of the soft rubber body. The outer edge of the soft rubber body is snapped into the slot.

[0011] Preferably, the bottom cover has a groove on its surface corresponding to the protrusion, and the bottom cover is engaged with the protrusion through the groove. The connection between the edge of the bottom cover and the outer shell is made by ultrasonic welding to fix the connection between the soft rubber body and the outer shell and to prevent the soft rubber body from falling off the groove of the outer shell.

[0012] Preferably, a limiting block is integrally formed around the top of the inner cavity of the outer shell to provide a limiting effect between the outer shell and the bottle opening.

[0013] Preferably, the outer wall of the fixing ring is integrally formed with a retaining strip around its perimeter. After the outer shell is connected to the bottle mouth through the soft rubber body, the retaining strip can limit the connection between the outer shell and the water pump, thereby enhancing the stability of the connection between the protective component and the water pump. Beneficial effects

[0014] By combining protective components, soft rubber components, and a bottom cover, an adapter can be assembled to fit various bottle neck diameters. The soft rubber components, through the design of the triangular blocks and the bending deformation of the straight body, can fold inward and fit tightly onto bottle necks of different diameters, thus achieving compatibility with multiple bottle neck models. Whether it is a small-diameter bottle or a large-diameter bottle, it can achieve quick installation and tight connection. Since the adapter is compatible with multiple bottle necks, users do not need to purchase special water pumps for different bottle neck specifications, reducing usage costs. Through the universal bottle neck adapter, the applicability of water pumps is expanded, effectively solving the problems mentioned in the background technology. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] As shown in Figures 1 to 9, a universal bottle neck adapter includes a protective component 1, a soft rubber component 2, and a bottom cover 3. The bottom cover 3 is ultrasonically welded to the bottom of the protective component 1. The soft rubber component 2 is sandwiched between the protective component 1 and the bottom cover 3, and its surface is snapped onto the bottle neck. The protective component 1, the soft rubber component 2, and the bottom cover 3 work together to install and adapt to different bottle neck diameters. Through the cooperation of the protective component 1, the soft rubber component 2, and the bottom cover 3, an adapter that can adapt to various bottle neck diameters is assembled, achieving compatibility with multiple bottle neck models. Whether it is a small-diameter bottle or a large-diameter bottle, it can achieve quick installation and tight connection. Since the adapter can be compatible with multiple bottle necks, users do not need to purchase special water pumps for different bottle neck specifications, reducing usage costs. The universal bottle neck adapter expands the applicability of water pumps.

[0027] The protective component 1 includes a housing 11, a retaining ring 12, a through slot 13, a retaining slot 14, and a protrusion 15. The housing 11 and the retaining ring 12 are integrally formed. The retaining ring 12 is installed on the top of the housing 11. The through slot 13 is opened at the center of the top of the housing 11 and is located inside the retaining ring 12. The retaining slot 14 is opened around the bottom of the housing 11. The protrusion 15 is located at the bottom of the housing 11 and is located at the outer end of the retaining slot 14. The design of the housing 11 and the retaining ring 12 can protect the internal soft rubber component 2 from external impact or wear, and extend the service life of the adapter.

[0028] The soft rubber component 2 includes a soft rubber body 21, dividing grooves 22, and holes 23. The dividing grooves 22 are arranged in a circular array at the bottom of the soft rubber body 21. Between two adjacent dividing grooves 22, there are sheet-like triangular blocks 24 that cooperate with the bottle mouth. Multiple sheet-like triangular blocks 24 are folded inward and snapped onto the bottle mouth. The holes 23 are located at the top of the sheet-like triangular blocks 24 and at the center of the soft rubber body 21. The outer edge of the soft rubber body 21 is snapped into the slot 14. The design of the sheet-like triangular blocks 24 allows them to fold inward. The adapter fits snugly onto bottle necks of different diameters, achieving compatibility with various bottle neck models. Because the triangular plate 24 wraps around the bottle neck and has elasticity around the perimeter, the adapter and the bottle neck will always remain concentric and will not shift. At the same time, because the triangular plate 24 is made of silicone, it can fold inward. If you want to remove the adapter from the bottle neck, it will be resisted by the elasticity of the silicone, so that the adapter will not easily fall off the bottle neck. In this way, the adapter will be very securely installed on the bottle neck.

[0029] The bottom cover 3 has a groove 4 on its surface corresponding to the protrusion 15. The bottom cover 3 is engaged with the protrusion 15 through the groove 4. The connection between the edge of the bottom cover 3 and the outer shell 11 is ultrasonically welded to fix the connection between the soft rubber body 21 and the outer shell 11 and prevent the soft rubber body 21 from falling off the slot 14 of the outer shell 11. The engagement design between the bottom cover 3 and the protrusion 15 of the outer shell 11 can prevent the soft rubber component 2 from falling off the slot 14 of the outer shell 11, ensuring the stability of the overall structure of the adapter. The fixing effect of the bottom cover 3 further enhances the firmness between the soft rubber component 2 and the bottle mouth.

[0030] The top of the inner cavity of the outer shell 11 is integrally formed with a limiting block 5, which is used to limit the position between the outer shell 11 and the bottle mouth, and prevent the adapter from shifting or rotating during use.

[0031] The outer wall of the fixing ring 12 is integrally formed with a retaining strip 6 around its perimeter. After the outer shell 11 is connected to the bottle mouth through the soft rubber body 21, the retaining strip 6 can limit the connection between the outer shell 11 and the water pump, thereby enhancing the stability of the connection between the protective component 1 and the water pump.

[0032] In actual use, the water pump is installed on a ring of circular soft rubber components 2 on the top of the adapter. The bottom surface of the soft rubber components 2 is divided into multiple pieces, and the bottom cover 3 is to prevent the soft rubber components 2 from coming off.

[0033] When the adapter is then installed on the bottle, the multiple sheet-like triangular blocks 24 of the soft rubber component 2 are squeezed and folded inward. Since the sheet-like triangular blocks 24 are composed of multi-piece silicone material, as long as the diameter of the bottle opening does not exceed the maximum diameter of the sheet-like triangular blocks 24 after folding, the bottle opening can be assembled onto the adapter.

[0034] When the water bottle is attached to the adapter, the multi-piece triangular block 24 will wrap around the bottle mouth, and there is elasticity around the whole circle, so the adapter and the bottle mouth will always remain concentric and will not shift. At the same time, because the triangular block 24 is folded inward, if the adapter is pulled off the bottle mouth, it will be resisted by the spring resistance of the triangular block 24, so that the adapter will not easily fall off the bottle mouth. In this way, the adapter will be very secure and stable assembled on the bottle mouth.

[0035] This solution is compatible with various bottle neck models, enabling quick installation and tight connection for both small-diameter and large-diameter bottles. Since the adapter is compatible with multiple bottle necks, users do not need to purchase dedicated water pumps for different bottle neck sizes, reducing usage costs. The universal bottle neck adapter expands the application scenarios and scope of the water pump.
