The utility model provides a straw.
In an embodiment of the utility model, as shown with reference to fig. 1, the straw includes interior body 1 and outer body 2, and the periphery of interior body 1 is located to outer body 2 cover, encloses between outer body 2 and the interior body 1 and closes and form inlet channel 3, and outer body 2 is equipped with air inlet 21 and gas outlet 22, and air inlet 21 and gas outlet 22 set up at the interval on the length direction of outer body 2, and all are linked together with inlet channel 3.
Through so, when the user inserts the straw and inhales in the beverage bottle, air inlet 21 is located the outside of beverage bottle, air inlet 21 is located the external world promptly, gas outlet 22 is located the beverage bottle, external air can get into inlet channel 3 through air inlet 21, flow through in the inlet channel 3 back from gas outlet 22 flows in the beverage bottle, make the internal gas pressure of beverage bottle keep equal with atmospheric pressure, perhaps external atmospheric pressure accessible inlet channel transmits to the beverage bottle in, make the internal gas pressure of beverage bottle keep equal with atmospheric pressure, when avoiding appearing the bottle internal pressure not enough, inhale hard and not smooth phenomenon.
Specifically, interior body 1 and outer body 2 are hollow structure, and interior body 1 encloses into and inhales the passageway, and simultaneously, interior body 1 will inhale and inhale that passageway and inlet channel separate completely, and the beverage that flows through in avoiding inhaling the passageway gets into the inlet channel in shines into the jam to the inlet channel, leads to the inlet channel to play the effect of balanced beverage bottle internal gas pressure. The inner tube 1 and the outer tube 2 may be made of the same material.
In one embodiment, inner tube 1 has a suction end, and air inlet 21 is disposed proximate the suction end.
In particular, when the outer body 2 has a first end near the suction end, the air inlet 21 is provided at the first end of the outer body 2, wherein,
referring to fig. 1, when the end surface of the first end of the outer tube 2 is close to or flush with the end surface of the suction end of the inner tube 1, the air inlet 21 is preferably opened on the tube wall of the first end of the outer tube 2, so as to prevent the user from sucking on the suction end of the inner tube 1, and the end surface of the first end of the outer tube 2 may be sucked by mistake, if the air inlet 21 is opened on the end surface of the first end of the outer tube 2, the air in the air inlet channel 3 may be sucked away to form a negative pressure, so that the beverage may flow into the air inlet channel 3, so that the air inlet channel 3 is blocked, and the effect of balancing the air pressure in the beverage bottle is lost;
referring to fig. 2, when the end surface of the first end of the outer tube 2 and the end surface of the suction end of the inner tube 1 are spaced apart from each other along the length of the inner tube 1, the air inlet 21 is optionally opened on the end surface of the first end of the outer tube 2 and/or the tube wall of the first end of the outer tube 2, so that, since the end surface of the first end of the outer tube 2 and the end surface of the suction end of the inner tube 1 have a certain interval, when a user sucks on the suction end of the inner tube 1, the end surface of the first end of the outer tube 2 cannot be sucked by mistake, so as to prevent the beverage from flowing into the air inlet channel 3, so that the air inlet channel 3 is blocked and the effect of balancing the internal pressure of the beverage bottle is lost, and at this time, the air inlet 21 is preferably opened on the end surface and the tube wall of the first end of the outer tube 2.
In an embodiment, the number of the air inlets 21 is plural, and the plural air inlets 21 are spaced along the circumference of the outer tube 2, so that the air inlet channel 3 is better communicated with the outside, the air pressure in the beverage bottle is stably balanced, even if part of the air inlets 21 are blocked, the air inlet channel 3 can maintain the function of balancing the air pressure in the beverage bottle, and the reliability is good.
In an embodiment, the air inlet 21 is a circular through hole, and the diameter of the air inlet 21 is 1mm to 2mm, and optionally, the diameter of the air inlet 21 is 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc., which is not limited herein.
Thus, in the range of the diameter, the air inlet 21 can achieve good effect of communicating the air inlet channel 3 with the outside, and meanwhile, most of particle dust outside is difficult to enter the air inlet channel 3 through the air inlet 21, so that the inside of the air inlet channel 3 can be kept clean.
In one embodiment, the air outlet 22 is located away from the suction end.
Specifically, when the outer tube 2 has a second end far away from the sucking end, the end of the inner tube 1 far away from the sucking end is a puncturing end, and the air outlet 22 is disposed at the second end of the outer tube 2, wherein, referring to fig. 1, the end face of the second end of the outer tube 2 is close to or flush with the end face of the puncturing end of the inner tube 1, after the straw is inserted into the beverage bottle, the puncturing end of the inner tube 1 and the second end of the outer tube 2 are both soaked in the beverage, at this time, the external air pressure is transmitted into the beverage bottle through the air inlet channel and the liquid beverage, so as to maintain the air pressure in the beverage bottle equal to the external air pressure.
In an embodiment, the number of the air outlets 22 is plural, and the plural air outlets 22 are spaced along the circumference of the outer tube 2, so that the air inlet channel 3 is better communicated with the interior of the beverage bottle, and the air pressure in the beverage bottle is stably balanced, even if some air outlets 22 are blocked, the air inlet channel 3 can maintain the function of balancing the air pressure in the beverage bottle, and the reliability is good.
In an embodiment, the air outlet 22 is a circular through hole, the diameter of the air outlet 22 is optionally 1mm to 2mm, and the diameter of the air outlet 22 is optionally 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm, 1.9mm, 2mm, etc., which is not limited herein.
Thus, in this diameter range, the air outlet 22 can serve as a good communication between the air inlet passage 3 and the beverage bottle.
In an embodiment, the end of the inner tube 1 far away from the sucking end extends out from the end of the outer tube 2 far away from the sucking end, and is arranged at an interval with the end of the outer tube 2 far away from the sucking end in the length direction of the inner tube 1, and encloses to form the air outlet 22, through this, after the straw penetrates into the beverage bottle, the end of the inner tube 1 far away from the sucking end is soaked in the beverage, and the end of the outer tube 2 far away from the sucking end is located above the liquid level of the beverage, the external air can flow through the air inlet channel 3 and enter the beverage bottle from the air outlet 22 enclosed by the inner tube 1 and the outer tube 2, and the effect of maintaining the air pressure in the beverage bottle equal to the external air pressure is achieved.
In an embodiment, one end of the inner tube 1 away from the drinking end is a piercing end, and an end surface of the piercing end is inclined, so that the drinking straw can easily pierce through a bottle cap of the beverage bottle through the piercing end and extend into the beverage bottle for drinking.
In an embodiment, the suction pipe further comprises a support 4, the support 4 is located in the air inlet channel 3 and connects the outer wall of the inner pipe body 1 and the inner wall of the outer pipe body 2, and the support 4 is used for keeping the relatively fixed position between the outer pipe body 2 and the inner pipe body 1, namely, has a holding effect on the air inlet channel.
The above is only the optional embodiment of the present invention, and not the scope of the present invention is limited thereby, all the equivalent structure changes made by the contents of the specification and the drawings are utilized under the inventive concept of the present invention, or the direct/indirect application in other related technical fields is included in the patent protection scope of the present invention.
