Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a sealed water-filling bottle with a leak-proof function. Background Art

[0002] With the continuous development of endoscopic technology, digestive endoscopy has become an indispensable means of diagnosis and treatment of digestive system diseases. During the endoscopic examination, since the endoscope lens is easily sticky to body fluids and foreign matter, which affects the smooth progress of the examination, it is necessary to use the sterile liquid contained in the water bottle to clean the lens.

[0003] Existing water filling bottles generally consist of a bottle body and a bottle cap, which is screwed onto the opening of the bottle body. When the sterile liquid in the water filling bottle is consumed, the bottle cap needs to be unscrewed for refilling. After long-term use, the connection between the bottle cap and the bottle body is less sealed due to repeated friction, which is prone to leakage, affecting the use of the water filling bottle. Utility Model Content

[0004] The purpose of the utility model is to provide a sealed water filling bottle with a simple structure and reasonable design and a leak-proof function in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] The bottle cap is screwed onto the top of the bottle cap, and a silicone plug is fixedly connected to the top wall of the inner cavity of the bottle cap, and a drainage structure is installed on the silicone plug, and a flange with an annular structure is provided on the peripheral side of the bottom end of the silicone plug, and an outer air bag with an annular structure is fixedly connected to the outer wall of the bottom end of the bottle cap, and an inner air bag is fixedly connected to the inner wall of the bottom end of the bottle cap and is arranged in alignment with the outer air bag, and a plurality of communicating holes are opened on the bottle neck between the outer air bag and the inner air bag, and the outer air bag and the inner cavity of the inner air bag are connected through the communicating holes, and an annular support plate is fixedly connected to the peripheral side of the bottle neck below the outer air bag, and the upper surface of the annular support plate is in contact with the lower surface of the outer air bag, and after the bottle cap is screwed tightly, the inner air bag is positioned relative to the flange provided on the peripheral side of the bottom end of the silicone plug.

[0007] As a further optimization solution of the present invention, the top of the bottle neck is provided with an external thread, the bottle cap is screwed and fixed to the bottle neck via the external thread, and the outer side wall of the bottle cap is provided with a plurality of annularly distributed anti-slip grooves.

[0008] As a further optimization solution of the present invention, the silicone plug has a cylindrical structure, the outer diameter of the silicone plug is smaller than the inner diameter of the bottleneck, and a through hole is opened in the center of the silicone plug.

[0009] As a further optimization scheme of the present invention, the drainage structure includes a drainage tube that penetrates the silicone plug through a through hole and then penetrates the top wall of the bottle cap. The peripheral side of the drainage tube is fixed to the silicone plug, and the bottom end of the drainage tube is flush with the bottom end of the silicone plug.

[0010] As a further optimization solution of the present invention, a joint is fixedly connected to the top of the liquid discharge pipe, and a valve is installed at the connection between the liquid discharge pipe and the top wall of the bottle cap.

[0011] As a further optimization solution of the present invention, when the bottle cap is screwed onto the bottle neck, the bottom end height of the bottle cap is lower than the upper surface height of the outer airbag.

[0012] The beneficial effect of the present utility model is that: during the screwing process of the bottle cap, it can cooperate with the annular support plate to squeeze the outer air bag to deform, and squeeze the air in the outer air bag into the inner air bag through the connecting hole, so that the internal air pressure of the inner air bag increases and expands into the bottleneck. At the same time, after the bottle cap is screwed, the flange inner air bag arranged on the side around the bottom end of the silicone plug is aligned, and the expanded inner air bag will cling to the flange to form a sealing structure for sealing, thereby avoiding as much as possible the problem of leakage caused by the connection between the bottle cap and the bottle body of the existing water filling bottle after long-term use due to repeated rotation friction.

[0018] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0019] Example

[0020] like Figure 1 - Figure 4 As shown, a sealed water-filling bottle with a leak-proof function comprises a bottle body 1 with a bottleneck 2 integrally formed on the top, the bottle body 1 is made of a flexible material, a bottle cap 4 is mounted on the top of the bottleneck 2, an external thread 3 is provided on the top of the bottleneck 2, the bottle cap 4 is screwed to the bottleneck 2 via the external thread 3, and a plurality of annular anti-slip grooves 5 are provided on the outer wall of the bottle cap 4 to increase the friction between the outer wall of the bottle cap 4 and the palm of the user, making it easier for the user to twist the bottle cap 4 to open or close the bottle cap 4;

[0021] A silicone plug 6 is fixedly connected to the top wall of the inner cavity of the bottle cap 4. The silicone plug 6 is cylindrical in structure. The outer diameter of the silicone plug 6 is smaller than the inner diameter of the bottleneck 2. This can minimize the friction between the silicone plug 6 and the inner wall of the bottleneck 2 when the user turns the bottle cap 4, thereby forming a damping effect and making it inconvenient for the user to open or close the bottle cap 4.

[0022] A through hole is provided in the center of the silicone plug 6, and a drainage structure is installed on the silicone plug 6. The drainage structure includes a drainage tube 7 that passes through the silicone plug 6 through the through hole and then passes through the top wall of the bottle cap 4. The circumference of the drainage tube 7 is fixed to the silicone plug 6, and the bottom end of the drainage tube 7 is flush with the bottom end of the silicone plug 6, so that when the bottle body 1 is in an inverted state, the sterile liquid contained in the bottle body 1 can be discharged through the drainage tube 7, thereby minimizing the residual sterile liquid in the bottle body 1.

[0023] The top of the drainage tube 7 is fixedly connected to a joint 9, and a valve 8 is installed at the connection between the drainage tube 7 and the top wall of the bottle cap 4. When in use, the user can connect the external cleaning pipe to the drainage tube 7 through the joint 9, then open the valve 8 and squeeze the bottle body 1 to squeeze out the sterile liquid to clean the endoscope lens;

[0024] A flange 10 having an annular structure is provided around the bottom end of the silicone plug 6. An outer airbag 11 having an annular structure is fixedly connected to the outer wall of the bottom end of the bottleneck 2. An inner airbag 12 arranged in alignment with the outer airbag 11 is fixedly connected to the inner wall of the bottom end of the bottleneck 2. A plurality of communication holes 13 are provided on the bottleneck 2 between the outer airbag 11 and the inner airbag 12. The inner cavities of the outer airbag 11 and the inner airbag 12 are connected through the communication holes 13, so that the air in the outer airbag 11 and the inner airbag 12 can be transferred through the communication holes 13.

[0025] An annular support plate 14 is fixedly connected to the periphery of the bottleneck 2 below the outer airbag 11. The upper surface of the annular support plate 14 fits with the lower surface of the outer airbag 11. When the bottle cap 4 is screwed to the bottleneck 2, the bottom end height of the bottle cap 4 is lower than the upper surface height of the outer airbag 11, and the inner airbag 12 is relative to the flange 10 set on the periphery of the bottom end of the silicone plug 6.

[0026] It should be noted that, when using this sealed water filling bottle with leak-proof function, the bottle cap 4 screwed on the top of the bottleneck 2 is opened, and an appropriate amount of sterile liquid is injected into the bottle body 1, and then the silicone plug 6 is inserted into the bottleneck 2, and the bottle cap 4 is screwed back again. Since the bottom end height of the bottle cap 4 is lower than the upper surface height of the outer air bag 11 when the bottle cap 4 and the bottleneck 2 are screwed together, the bottle cap 4 will cooperate with the annular support plate 14 located below the outer air bag 11 to squeeze the outer air bag 11 from above during the screwing process, so that the outer air bag 11 is squeezed and deformed. At this time, the air in the outer air bag 11 Due to the extrusion effect, the gas will enter the inner air bag 12 through the connecting hole 13, and squeeze the inner air bag 12 to expand into the neck of the bottle 2. At the same time, after the bottle cap 4 is screwed tightly, the flange 10 arranged on the peripheral side of the bottom end of the silicone plug 6 will slide into the neck of the bottle 2 to a position opposite to the inner air bag 12. At this time, the inner wall of the expanded inner air bag 12 will cling to the flange 10 to form a sealing structure to seal the sterile liquid in the bottle body 1, thereby avoiding the problem that the connection between the bottle cap 4 and the bottle body 1 is easily leaked due to repeated rotation friction after long-term use of the existing water filling bottle.

[0027] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
