Description

Technical Field

[0001] This utility model belongs to the field of liquid filling, specifically relating to a liquid filling and usage device that can isolate air. Background Technology

[0002] Because rigid containers cannot be easily deformed, an equal volume of air must flow in to maintain the same air pressure inside and outside the packaging so that the liquid can flow out smoothly. This means that the liquid may come into contact with the air and various bacteria, viruses, and foreign particles in the air, causing secondary contamination of the liquid. Therefore, it is necessary to separate the liquid from the air. Flexible containers are easily damaged during processing and use.

[0003] To address this, researchers incorporated a flexible partition material inside the container, dividing it into a pressure stabilization chamber and a storage chamber. The storage chamber stores the filled liquid, while the pressure stabilization chamber connects to the external environment, ensuring stable pressure during filling and use. This guarantees smooth inflow and outflow of the liquid, ensuring durability while preventing air contamination.

[0004] Traditionally, a vent is used to connect the pressure stabilization chamber to the external environment, and a rubber plug is used to control the pressure. However, the traditional device is cumbersome and laborious to adjust the pressure using a rubber plug, which is not conducive to personnel use. Utility Model Content

[0005] The purpose of this invention is to provide a liquid filling and use device that can isolate air, so as to solve the problem that the traditional device uses rubber stoppers for pressure adjustment, which is troublesome and laborious and not conducive to personnel use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An air-isolated liquid filling and use device, comprising a main body and a pressure regulating mechanism;

[0008] The main body includes an outer shell, a partition bag is provided inside the outer shell, and an outlet is provided at the bottom of the outer shell. The outlet and the opening of the partition bag are connected by a connecting ring.

[0009] The pressure regulating mechanism includes a pressure relief seat disposed on the top of the housing, a sealing shell rotatably disposed on the top of the pressure relief seat, a pressure relief groove disposed inside the pressure relief seat, and a pressure relief hole disposed on the upper surface of the sealing shell.

[0010] Preferably, the pressure relief groove is adapted to the pressure relief hole.

[0011] Preferably, the outer surface of the pressure relief seat is provided with a sealing block, the inner surface of the sealing shell is provided with a movable groove, and the outer surface of the pressure relief seat at the bottom of the movable groove is provided with a whistle hole.

[0012] Preferably, the movable groove is located around the sealing block.

[0013] Preferably, the upper surface of the sealing shell surrounding the pressure relief hole is provided with an inclined surface, and the top of the outer shell surrounding the pressure relief seat is provided with a support seat, the support seat and the inclined surface being at the same horizontal plane.

[0014] Preferably, the outer surface of the separator bag is provided with a plurality of elastic bands, the inner surface of the connecting ring is connected to the outer shell through an internal thread, and the outer surface of the connecting ring is connected to the sealing cap through an external thread.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention allows for air exchange between the inside and outside of the housing by slightly rotating the sealing shell during liquid filling or use, aligning the pressure relief groove with the pressure relief hole, thus ensuring internal air pressure balance. During liquid transportation or storage, the sealing shell is rotated in the opposite direction to offset the pressure relief groove from the pressure relief hole, ensuring the housing's airtightness and facilitating pressure adjustment by personnel.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0026] As attached Figure 1 and attached Figure 3 As shown:

[0027] Example 1: This example provides a liquid filling and use device that can isolate air, including a main body 1 and a pressure regulating mechanism 2; the main body 1 includes a shell 101, a separator bag 102 is provided inside the shell 101, an outlet 104 is provided at the bottom of the shell 101, and the outlet 104 is connected to the opening of the separator bag 102 by a connecting ring 105; the pressure regulating mechanism 2 includes a pressure relief seat 201 provided on the top of the shell 101, a sealing shell 202 is rotatably provided on the top of the pressure relief seat 201, a pressure relief groove 203 is provided inside the pressure relief seat 201, and a pressure relief hole 204 is provided on the upper surface of the sealing shell 202.

[0028] The outer shell 101 can be connected or closed by rotating the sealing shell 202, which is convenient for personnel to use. The sealing shell 202 is confined to the pressure relief seat 201, which can effectively prevent loss.

[0029] The outer shell 101 has a cylindrical structure. During liquid filling, the sealing shell 202 is rotated first, causing it to rotate on the pressure relief seat 201 until the pressure relief groove 203 aligns with the pressure relief hole 204. At this time, air circulates inside and outside the outer shell 101. Then, liquid is filled into the separator bag 102 through the bottom opening. When water enters the separator bag 102, it will expand it, thereby squeezing the air inside the outer shell 101 out of the pressure relief hole 204, ensuring the air pressure balance inside the outer shell 101. After the liquid filling is completed, the sealing shell 202 is rotated again to allow the pressure relief groove to align with the pressure relief seat 203. The pressure relief groove 203 and the pressure relief hole 204 are offset. When the device is transported to the place of use and the filled liquid needs to be used, the pressure relief groove 203 and the pressure relief hole 204 are offset again. Air enters the outer shell 101 from the pressure relief groove 203, which then squeezes the separator bag 102 and squeezes out the liquid inside the separator bag 102. Since the air enters the device through the pressure relief groove 203 to ensure air pressure balance, air will not enter from the opening of the separator bag 102. The separator bag 102 will separate the air from the liquid, which facilitates drainage and avoids bacterial and viral contamination of the liquid.

[0030] Specifically, the pressure relief groove 203 is adapted to the pressure relief hole 204.

[0031] As attached Figure 1 and attached Figure 2 As shown:

[0032] Specifically, the outer surface of the separator bag 102 is provided with several elastic bands 103, the inner surface of the connecting ring 105 is connected to the outer shell 101 through the internal thread 107, and the outer surface of the connecting ring 105 is connected to the sealing cap 106 through the external thread 108.

[0033] As can be seen from the above, the elastic band 103 will be stretched and expanded when filling with liquid, and when it is necessary to discharge the liquid for use.

[0034] As attached Figure 1 and attached Figure 3 As shown:

[0035] Example 2: This example provides a liquid filling and use device that can isolate air, including a main body 1 and a pressure regulating mechanism 2; the main body 1 includes a shell 101, a separator bag 102 is provided inside the shell 101, an outlet 104 is provided at the bottom of the shell 101, and the outlet 104 is connected to the opening of the separator bag 102 by a connecting ring 105; the pressure regulating mechanism 2 includes a pressure relief seat 201 provided on the top of the shell 101, a sealing shell 202 is rotatably provided on the top of the pressure relief seat 201, a pressure relief groove 203 is provided inside the pressure relief seat 201, and a pressure relief hole 204 is provided on the upper surface of the sealing shell 202.

[0036] The outer shell 101 can be connected or closed by rotating the sealing shell 202, which is convenient for personnel to use. The sealing shell 202 is confined to the pressure relief seat 201, which can effectively prevent loss.

[0037] The outer shell 101 has a cylindrical structure. During liquid filling, the sealing shell 202 is rotated first, causing it to rotate on the pressure relief seat 201 until the pressure relief groove 203 aligns with the pressure relief hole 204. At this time, air circulates inside and outside the outer shell 101. Then, liquid is filled into the separator bag 102 through the bottom opening. When water enters the separator bag 102, it will expand it, thereby squeezing the air inside the outer shell 101 out of the pressure relief hole 204, ensuring the air pressure balance inside the outer shell 101. After the liquid filling is completed, the sealing shell 202 is rotated again to allow the pressure relief groove to align with the pressure relief seat 203. The pressure relief groove 203 and the pressure relief hole 204 are offset. When the device is transported to the place of use and the filled liquid needs to be used, the pressure relief groove 203 and the pressure relief hole 204 are offset again. Air enters the outer shell 101 from the pressure relief groove 203, which then squeezes the separator bag 102 and squeezes out the liquid inside the separator bag 102. Since the air enters the device through the pressure relief groove 203 to ensure air pressure balance, air will not enter from the opening of the separator bag 102. The separator bag 102 will separate the air from the liquid, which facilitates drainage and avoids bacterial and viral contamination of the liquid.

[0038] Specifically, the pressure relief groove 203 is adapted to the pressure relief hole 204.

[0039] As attached Figure 3 and attached Figure 4 As shown:

[0040] Specifically, the outer surface of the pressure relief seat 201 is provided with a sealing block 205, the inner surface of the sealing shell 202 is provided with a movable groove 206, and the outer surface of the pressure relief seat 201 at the bottom of the movable groove 206 is provided with a whistle hole 207.

[0041] Specifically, the movable groove 206 is located around the sealing block 205.

[0042] Specifically, the upper surface of the sealing shell 202 surrounding the pressure relief hole 204 is provided with an inclined surface 209, and the top of the outer shell 101 surrounding the pressure relief seat 201 is provided with a support seat 208, with the support seat 208 and the inclined surface 209 on the same horizontal plane.

[0043] As attached Figure 1 and attached Figure 2 As shown:

[0044] Specifically, the outer surface of the separator bag 102 is provided with several elastic bands 103, the inner surface of the connecting ring 105 is connected to the outer shell 101 through the internal thread 107, and the outer surface of the connecting ring 105 is connected to the sealing cap 106 through the external thread 108.

[0045] As can be seen from the above, by setting the sealing block 205 and the movable groove 206, the sealing shell 202 can move slightly up and down on the pressure relief seat 201. Thus, if the staff forgets to rotate the sealing shell 202 and aligns the pressure relief groove 203 with the pressure relief hole 204 during the filling process, the air pressure inside the device will push the sealing shell 202 upward, so that the pressure relief groove 203 and the pressure relief hole 204 are automatically connected. A warning sound will be emitted through the whistle hole 207 to remind the staff. This can effectively prevent the situation where the separator bag 102 is squeezed and ruptured due to the staff forgetting that the outer shell 101 is connected.

[0046] As attached Figure 4 As shown, the pressure relief seat 201 and the sealing shell 202 are inclined. After the liquid is filled, the device will be inverted and placed on the ground. If the pressure relief groove 203 and the pressure relief hole 204 are still aligned, their height will be higher than the support seat 208, which will lift the device and make it unstable, thus reminding the staff. When the staff rotates the sealing shell 202 to make the pressure relief groove 203 and the pressure relief hole 204 misaligned, the inclined surface 209 will be on the same horizontal plane as the support seat 208, ensuring stability.

[0047] If the pressure relief groove 203 and the pressure relief hole 204 are misaligned but the whistle hole 207 is exposed, it means that the sealing shell 202 has been lifted. At this time, the device is turned upside down and placed on the ground. The device will use its own weight to press the sealing shell 202 back into its original position. No manual reset is required, which is convenient for personnel to use.
