Coffee cup straw with stirring blade

Abstract

The coffee cup straw with the stirring blade comprises a straw body, a movable pipe, a shaft pipe and the stirring blade, the movable pipe is located at the bottom end of the straw body, the straw body is in running fit with the movable pipe through the shaft pipe, and a positive pressure channel and a negative pressure channel which are used for drinking coffee are formed in the straw body, the movable pipe and the shaft pipe respectively. The stirring blades are annularly distributed on the outer surface of the movable pipe, and the bottom end of the straw body is of an arc-shaped structure. According to the coffee cup straw with the stirring blades, through a conventional straw drinking method, coffee can flow into the water conveying pipeline from the through cavity and penetrate through the positive and negative pressure channel to be discharged from the other end of the straw body, and the diameter difference exists between the water conveying pipeline and the through cavity, so that the situation that coffee liquid splashes around due to the fact that the air pressure discharging speed is too high and the rotating speed of the stirring blades is too high is avoided; therefore, the practicability of the whole structure is improved.

[0002] A coffee cup straw is a tool used to drink coffee, usually made of materials such as plastic, silicone or metal. The straw is inserted into the coffee cup and the coffee is sucked into the mouth through suction. This design can prevent caffeine from spilling, maintain hygiene when drinking, and is easy to carry.

[0003] However, before drinking coffee, some coffee ingredients settle at the bottom of the cup, which affects the taste of the coffee. A common solution is to control the straw to stir inside the coffee cup, which is not only troublesome to operate, but also causes hands to come into contact with the straw, which can easily cause cross infection. Therefore, a coffee cup straw that does not require hand-held stirring is needed to solve the above problem. Utility Model Content

[0006] As a preferred technical solution of the present invention, the movable tube is fixedly connected to the shaft tube, and the shaft tube is movably connected to the straw body.

[0007] As a preferred technical solution of the present invention, a disposable suction nozzle is movably mounted on the outer surface of the top of the straw body.

[0008] As a preferred technical solution of the present invention, a water delivery pipeline communicating with the positive and negative pressure channels is provided inside the stirring blade, and the diameter of the water delivery pipeline is smaller than the diameter of the through cavity.

[0009] As a preferred technical solution of the present invention, the bottom end of the movable tube is in an arc-shaped structure.

[0010] Compared with the prior art, the utility model has the following beneficial effects: the coffee cup straw with stirring blades:

[0011] 1. The coffee can be stirred and drunk by blowing and sucking, avoiding cross infection caused by stirring the coffee with a handheld straw. It is easy and hygienic to use, thereby increasing the overall practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figure 1-3 The utility model provides a technical solution: a coffee cup straw with stirring blades, comprising a straw body 1, a movable tube 2, a shaft tube 3 and stirring blades 4, the movable tube 2 is located at the bottom end of the straw body 1, the straw body 1 and the movable tube 2 are rotatably matched through the shaft tube 3, the straw body 1, the movable tube 2 and the shaft tube 3 are respectively provided with positive and negative pressure channels 7 for drinking coffee, the stirring blades 4 are annularly distributed on the outer surface of the movable tube 2, and the bottom end of the straw body 1 is an arc-shaped structure.

[0018] The movable tube 2 is fixedly connected to the shaft tube 3, and the shaft tube 3 is movably connected to the straw body 1. The movable tube 2 can rotate with the straw body 1 as the center point through the shaft tube 3, and through the rotation, the stirring blades 4 on the outer surface are driven to stir the coffee cup.

[0019] A disposable suction nozzle 6 is movably mounted on the outer surface of the top of the straw body 1. The disposable suction nozzle 6 can be used as selected. The disposable suction nozzle 6 is made of plastic and is convenient for outdoor carrying and use.

[0020] A water pipe 8 communicating with the positive and negative pressure channels 7 is provided inside the stirring blade 4. The diameter of the water pipe 8 is smaller than the diameter of the through cavity 5. The water pipe 8 of the stirring blade 4 is communicated with the positive and negative pressure channels 7. The coffee liquid is also transported to the positive and negative pressure channels 7 through the water pipe 8 and finally discharged from the top of the straw body 1 to form a drinking channel.

[0021] As a preferred technical solution of the present invention, the bottom end of the movable tube 2 is in an arc-shaped structure.

[0022] Working principle: before use, the straw body 1 is passed through the center hole of the coffee cup cover. The coffee cup cover should be provided with heat dissipation holes, and the bottom end of the movable tube 2 is fitted with the bottom end of the coffee cup. When drinking, it is necessary to blow air into the straw body 1 so that the inside of the straw body 1, the movable tube 2 and the stirring blade 4 are in a positive pressure state, and the air flow is ejected from the through cavity 5. Under the impetus of the positive pressure air flow, the movable tube 2 rotates with the straw body 1 as the center point through the shaft tube 3, and the stirring blade 4 distributed in an annular manner outside the shaft tube 3 can stir the coffee, which can not only make the coffee raw materials mixed evenly, but also increase the heat exchange area of ​​the coffee liquid and increase the heat dissipation effect. When it is needed to drink, the method of use is the same as that of a conventional straw. The coffee flows into the water pipe 8 from the through cavity 5 and is discharged from the other end of the straw body 1 through the positive and negative pressure channels 7. Among them, there is a diameter difference between the water pipe 8 and the through cavity 5, which avoids the excessive speed of air pressure discharge, resulting in excessive rotation of the stirring blade 4 causing the coffee liquid to splash everywhere, thereby increasing the practicality of the overall structure.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
