Description

Technical Field

[0001] The utility model relates to the field of water purification equipment, in particular to a life straw. Background Art

[0002] LifeStraw is a portable water purification device designed to provide safe drinking water in field operations, picnics, emergency rescue, earthquakes and floods, etc. Its working principle is mainly to remove impurities, bacteria, viruses, heavy metals and other harmful substances in the water source through multi-layer filtration and purification technology, so as to obtain clean and safe drinking water.

[0003] A Chinese patent discloses an electric life straw (publication number: CN 218636802 U), which includes: a shell; a water inlet arranged on the shell; an air pump fixedly connected to the inside of the shell; a water outlet arranged on the shell; a water pipe connected between the water inlet and the water outlet, the water pipe has an opening connected to the air pump; and a filter element located in the water pipe.

[0004] The above patent cannot be adapted to common mineral water bottle containers. Users may have difficulty finding suitable containers to use in the wild or in emergency situations, and lack the ability to continuously supply water. If there is no continuous water supply, users will not be able to obtain enough water through the life straw. In the wild environment, especially when water sources are scarce or there is a need for long periods of time without water supply, this shortcoming is particularly prominent. Users can only drink water immediately when using the life straw. Moreover, users must always be close to the water source when using the life straw, which limits its flexibility and convenience. In the case of needing to move or leaving the water source for a long time, the life straw may not meet the needs of users. Utility Model Content

[0005] In view of the problems existing in the above-mentioned prior art, the utility model provides a life straw, which can effectively solve the problems existing in the above-mentioned prior art.

[0006] The technical solution of the utility model is:

[0007] According to one aspect of the utility model, it includes: a main body, the main body is provided with a water inlet, the main body is provided with a connecting seat for connecting to the bottle mouth of a container, the connecting seat is provided with a second air vent and the water inlet, the main body is provided with a first air vent outside the connecting seat, and the first air vent is communicated with the second air vent.

[0008] Furthermore, the connection seat is provided with an internal thread, and an annular protrusion is provided inside the connection seat; when the connection seat is connected to the bottle mouth of the container, the bottle mouth of the container is embedded between the annular protrusion and the internal thread.

[0009] Furthermore, an air plug is fixedly provided inside the second air vent, and the air plug is provided with an elastically deformable plug body; the plug body abuts against one end of the second air vent facing the connecting seat, and is used to close the second air vent.

[0010] Furthermore, the gas plug is provided with a first flange and a second flange, the first flange and the second flange are respectively clamped at two ends of the second vent hole, and the second flange extends outward to form the plug body.

[0011] Furthermore, a support block is provided in the middle of the second vent hole, a through hole is opened at the axis of the support block, and the gas plug is fixed in the through hole; two ends of the support block are respectively abutted against the first flange and the second flange.

[0012] Furthermore, the gas plug is made of silicone or rubber.

[0013] Furthermore, it also includes a water tank and a water pipe joint, the water pipe joint is fixed to the water tank, and the water inlet is detachably plugged into the water pipe joint.

[0016] Furthermore, a second groove is provided at the upper end of the water tank, and the main body can rotate 360° in the second groove.

[0017] By adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0018] First, the main body can be connected to common containers, which makes it extremely convenient to obtain safe drinking water outdoors or in emergency situations. Users do not need to carry additional filtering equipment or containers. They only need to connect the main body to common containers to start filtering and drinking immediately. In addition, the container can store water, so users do not need to be close to the water source at all times. When water is scarce, it can provide water supply, which improves the flexibility and convenience of the LifeStraw.

[0019] Secondly, when absorbing water, negative pressure is formed in the container, the container will shrink and deform, and the air outside the main body enters the container through the first vent hole and the second vent hole to balance the air pressure in the container.

[0020] Third, when the main body does not absorb water, the second vent is in a closed state, and the second flange abuts against the second vent; after the main body is connected to the container, when water is absorbed, a negative pressure is formed in the container, the edge of the second flange moves downward, the second vent is switched to an open state, and the air outside the main body enters the container through the ventilation pipe.

[0021] When the container does not need ventilation, the second vent is closed to effectively prevent dust, bacteria or other pollutants from entering the container. At the same time, it can also prevent odor from entering the container through the first vent. When you are outdoors, you may need to open the second vent frequently to keep the water flowing smoothly. When you are stationary, you can close the vent to prevent water from splashing out.

[0022] Fourthly, the water tank can also provide the function of storing water. If there is no common container outdoors, a water tank can be used to store water.

[0023] Fifthly, a second groove is provided at the upper end of the water tank, and the main body can rotate 360° in the second groove; the main body can rotate in all directions, so that the user can easily adjust the direction of the water tank no matter at what angle or posture the user drinks the water inside the water tank, without changing the position of the water tank or his own posture; especially when walking, driving or performing other activities, the convenience of use is greatly increased.
