Description

Technical Field

[0001] This application relates to the field of lifesaving equipment technology, and in particular to a lifesaving drinking water packaging that can be stored for a long time and consumed multiple times. Background Technology

[0002] Drinking water is a precious resource for everyone, and current drinking water is bottled or packaged in barrels, which are relatively fixed in size and shape and are very inconvenient to carry. However, using drinking water bags outdoors can solve the above problems very well.

[0003] However, existing drinking water bags all have a threaded neck at the opening, and the drinking water is sealed by directly connecting the bottle cap to the neck. But every time the bottle cap is opened to drink water, some air will directly enter the bag. This will inevitably bring bacteria and microorganisms contained in the outside air into the bag, thus affecting the shelf life of the water. Therefore, this utility model proposes a life-saving drinking water packaging that can be stored for a long time and consumed multiple times. Utility Model Content

[0004] The technical problem to be solved by this application is to provide a life-saving drinking water packaging that can be stored for a long time and consumed multiple times, thus solving the problem that existing outdoor drinking water bags are inconvenient for long-term storage of drinking water.

[0005] To solve the above problems, the following technical solutions are provided:

[0006] This solution is a life-saving drinking water packaging that can be stored for a long time and consumed multiple times. It includes a water storage bag, with a water outlet pipe at the top of the water storage bag. The top of the water storage bag has a threaded opening for water to be discharged. The bottom of the water outlet pipe is connected to a connecting plug that connects to the threaded opening. The water outlet pipe has a water outlet guide hole inside. The connecting plug has a through hole for the water outlet guide hole to communicate with the inside of the water storage bag. A first one-way valve is installed in the through hole to allow drinking water in the water storage bag to flow unidirectionally from the inside of the bag to the water outlet pipe.

[0007] By adopting the above technical solution: the water storage bag is equipped with a water outlet pipe for taking water from the water storage bag for drinking. The water storage bag and the water outlet pipe are connected to a connecting plug through a threaded opening, which makes it convenient to add water to the water storage bag. The connecting plug is also equipped with a one-way valve to prevent outside air from entering the bag through the water outlet pipe when taking water. This ensures that the water storage bag is always in an air-isolated state before the connecting plug is removed, and also ensures that drinking water can be stored in the water storage bag for a long time.

[0008] The water outlet pipe is equipped with a regulating valve for controlling the water output, and the water storage bag is equipped with a pressurizing mechanism to increase the pressure inside the bag.

[0009] By adopting the above technical solution, a regulating valve and a pressurizing mechanism are set up to facilitate water intake. The pressurizing mechanism pressurizes the water storage bag, and the regulating valve controls the outflow speed of the water in the outlet pipe to ensure the safety of drinking water.

[0010] The longitudinal section of the water outlet guide hole is flat. The regulating valve includes an inner sleeve and an outer sleeve that cooperate with each other. The inner sleeve is fixedly installed on the water outlet pipe. The inner sleeve is a constricted opening that tapers inward and has external threads on its outer surface. The inner sleeve has a tapered structure that matches the inner sleeve and has internal threads on its inner wall that cooperate with the external threads.

[0011] By adopting the above technical solution: the regulating valve squeezes the water outlet guide hole on the water outlet pipe by the cooperation of the inner sleeve and the outer sleeve. When the outer sleeve is tightened on the inner sleeve, no water flows out of the water outlet pipe. When the outer sleeve is loosened, water flows out of the water outlet pipe. Furthermore, the size of a certain cross-section in the water outlet guide hole can be changed by the tightness of the outer sleeve and the inner sleeve, so as to achieve the effect of opening and closing the flow of drinking water in the water outlet pipe and controlling the flow rate of drinking water.

[0012] The pressurization mechanism includes an air bladder and a pressure bladder. The air bladder is located inside the water storage bag, and the pressure bladder is fixed to one side of the water storage bag. The pressure bladder has an air chamber, an air inlet, an air outlet, and a pressure relief channel. One end of the air inlet and the air outlet are connected to the air chamber, the other end of the air inlet is connected to the air bladder, and the other end of the air outlet is connected to the outside air. A second one-way valve is provided in both the air inlet and the air outlet to allow drinking water to flow unidirectionally from the air outlet to the air inlet. One end of the pressure relief channel is connected to the air bladder, and the other end is connected to the outside air, with a threaded plug connected to that end of the pressure relief channel.

[0013] By adopting the above technical solution: adding an air bladder and a pressing bladder to the mechanism, squeezing the pressing bladder to inflate the air bladder, thereby reducing the volume inside the water storage bag, so that the drinking water has pressure to overflow, and the air bladder can be deflated through the pressure relief channel to reduce the pressure inside the water storage bag.

[0014] The connecting plug is equipped with a sealing gasket.

[0015] By adopting the above technical solution, water leakage between the connecting plug at the bottom of the water outlet pipe and the threaded opening on the water storage bag is avoided, thus improving the sealing performance of the water storage bag.

[0016] The above approach has the following advantages:

[0017] 1. In this application, the water storage bag is provided with a water outlet pipe for drawing water from the water storage bag. The water storage bag and the water outlet pipe are connected to a connecting plug through a threaded opening, which facilitates adding water to the water storage bag. The connecting plug is also provided with a one-way valve to prevent outside air from entering the bag through the water outlet pipe when drawing water. This ensures that the water storage bag is always in an air-isolated state before the connecting plug is removed, and also ensures that drinking water can be stored in the water storage bag for a long time.

[0018] 2. In this application, a regulating valve and a pressurizing mechanism are provided to facilitate water intake. The pressurizing mechanism pressurizes the water storage bag, and the regulating valve controls the outflow rate of the water in the outlet pipe to ensure the safety of drinking water.

[0024] The present invention will be described below with reference to the accompanying drawings and embodiments.

[0025] Example 1

[0026] This embodiment describes a package of emergency drinking water that can be stored for extended periods and consumed multiple times. Figure 1As shown, it includes a water storage bag 1, with a water outlet pipe 6 at the top of the water storage bag 1. The top of the water storage bag 1 has a threaded opening 101 for water outlet. The bottom end of the water outlet pipe 6 is connected to a connecting plug 4 connected to the threaded opening 101. The water outlet pipe 6 has a water outlet guide hole 601 inside. The connecting plug 4 has a through hole for communicating between the water outlet guide hole 601 and the inside of the water storage bag 1. A first one-way valve 8 is installed in the through hole to allow drinking water in the water storage bag 1 to flow unidirectionally from the inside of the bag to the water outlet pipe 6. The water storage bag 1 is equipped with a water outlet pipe 6 for drawing drinking water from the bag. The water storage bag 1 and the water outlet pipe 6 are connected to a connecting plug 4 via a threaded opening 101, facilitating the addition of water to the bag. The connecting plug 4 is also equipped with a one-way valve to prevent outside air from entering the bag through the water outlet pipe 6 when drawing water, thus ensuring that the water storage bag 1 remains airtight until the connecting plug 4 is removed, and guaranteeing long-term storage of drinking water within the bag. Furthermore, the connecting plug 4 is equipped with a sealing gasket 5. When the connecting plug 4 is tightened to the threaded opening 101, it prevents water leakage between the connecting plug 4 at the bottom of the water outlet pipe 6 and the threaded opening 101 on the water storage bag 1, improving the sealing performance of the water storage bag 1.

[0027] Specifically, the structure of the first one-way valve 8 applied to the connecting plug 4 is as follows: Figure 2 As shown, a valve body 801 is connected to the through hole of the first one-way valve 8. A channel 804 with a radial dimension that decreases from large to small is opened in the valve body 801. One end of the narrow opening of the channel 804 is connected to the water storage bag 1, and the other end is connected to the water outlet pipe 6. A valve ball 802 and a spring 803 are also provided in the channel 804. The spring 803 pushes the valve ball 802 against the narrow opening of the channel 804.

[0028] When in use, unscrewing the connecting plug 4 allows drinking water to be stored in the water storage bag 1. During water dispensing, the top of the water outlet pipe 6 can be used to collect water. Pressing the body of the water storage bag 1 causes the valve ball 802 inside the first one-way valve 8 to be pushed up, allowing drinking water to enter the water outlet pipe 6 through the diameter of the first one-way valve 8. When the pressing of the water storage bag 1 stops, the valve ball 802 inside the first one-way valve 8 is squeezed onto the narrow opening by the spring 803, preventing air from entering the bag through the first one-way valve 8. Therefore, the water storage bag 1 can isolate air when dispensing water, thereby extending the shelf life of the drinking water.

[0029] Example 2

[0030] The difference between this embodiment and Embodiment 1 is that a regulating valve 7 and a pressurizing mechanism are provided to facilitate water intake, such as... Figure 3 and Figure 4As shown, the regulating valve 7 is installed on the water outlet pipe 6, and the pressurizing mechanism is installed inside the water storage bag 1. The regulating valve 7 is used to control the water output, and the pressurizing mechanism is used to increase the pressure inside the water storage bag 1. The pressurizing mechanism pressurizes the water storage bag 1, and the regulating valve 7 controls the outflow speed of the water in the water outlet pipe 6 to ensure the safety of drinking water.

[0031] Specifically, in this embodiment, the longitudinal section of the water outlet guide hole 601 is flat, such as... Figure 3 or Figure 4 As shown, the regulating valve 7 includes an inner sleeve 702 and an outer sleeve 701 that cooperate with each other. The inner sleeve 702 is fixedly installed on the water outlet pipe 6. The inner sleeve 702 is an inwardly contracting constriction and has external threads on its outer surface. The inner sleeve 701 has a conical structure that adapts to the inner sleeve 702, and its inner wall has internal threads that cooperate with the external threads. The regulating valve 7 squeezes the water outlet guide hole 601 on the water outlet pipe 6 by the cooperation of the inner sleeve 702 and the outer sleeve 701. When the outer sleeve 701 is tightened on the inner sleeve 702, no water flows out of the water outlet pipe 6. When the outer sleeve 701 is loosened, water flows out of the water outlet pipe 6. Furthermore, the size of a certain cross-section in the water outlet guide hole 601 can be changed by the tightness of the outer sleeve 701 and the inner sleeve 702, so as to achieve the effect of opening and closing the flow of drinking water in the water outlet pipe 6 and controlling the flow rate of drinking water.

[0032] Further, the pressurization mechanism in this embodiment includes an airbag 2 and a pressure bladder 3. The airbag 2 is disposed inside the water storage bag 1, and the pressure bladder 3 is fixed to one side of the water storage bag 1. The pressure bladder 3 has an air chamber 301 inside, and the pressure bladder 3 has an air inlet 303, an exhaust 302, and a pressure relief 304. One end of the air inlet 303 and the exhaust 302 are both connected to the air chamber 301, the other end of the air inlet 303 is connected to the airbag 2, and the other end of the exhaust 302 is connected to the outside air. Both the air inlet 303 and the exhaust 302 are provided with... A second one-way valve allows drinking water to flow unidirectionally from the exhaust duct 302 to the air inlet duct 303. One end of the pressure relief duct 304 is connected to the airbag 2, and the other end is connected to the outside air. A threaded plug 305 is connected to the end of the pressure relief duct 304. The mechanism includes an airbag 2 and a pressing bladder 3. Squeezing the pressing bladder 3 inflates the airbag 2, thereby reducing the volume inside the water storage bag 1, so that the drinking water has pressure to overflow. The pressure relief duct 304 can release air from the airbag 2, reducing the pressure inside the water storage bag 1. The second one-way valve can use existing technology, which will not be described in detail here.

[0033] During use, such as Figure 3As shown, the outer sleeve 701 is screwed tightly onto the inner sleeve 702, ensuring that the water outlet 601 is closed. Then, by squeezing the pressure bladder 3, air is inflated into the air bladder 2, causing the water storage bladder to start to pressurize. When taking water, the outer sleeve 701 is slowly loosened, and drinking water sprays out from the water outlet 601, improving the convenience of taking water. After taking water, the pressure relief channel 304 is opened to release air from the air bladder 2, which can prevent the outer sleeve 701 from being accidentally loosened, thus avoiding waste of drinking water.

However, those skilled in the art should understand that these descriptions are exemplary and not intended to limit the scope of protection of the present invention. Furthermore, those skilled in the art can make various modifications and variations to the present invention based on the spirit and principles of the present invention, and these modifications and variations are also within the scope of the present invention.
