[0002] Straws are very widely used in daily necessities, and are often used in water cups, milk bottles, vacuum flasks and the like, and are indispensable components in feeding containers for infants and young children.

[0003] A straw is generally provided in the form of a tube that penetrates from top to bottom, and the end of the upper end of the straw for sucking is referred to as a straw nozzle. When the straw is used, the lower end of the straw is inserted into the liquid in a cup or a bottle, and the user holds the straw nozzle in the mouth to perform a sucking action, so that the liquid can be sucked into the mouth, which is convenient and fast.

[0004] However, during the process of drinking by the user through the straw, especially for people such as infants and young children who cannot well control the sucking force, if the sucking force is too large, the flow rate of the liquid in the straw will instantaneously increase, and when the straw nozzle is held in the mouth, it is generally in a position directly opposite the throat, and the liquid with the instantaneously increased flow rate will gush out of the straw nozzle and impact the throat, thereby causing splashing or water choking, which greatly reduces the use experience and brings discomfort to the user and may even cause danger, and this problem needs to be solved urgently.

[0036] The following will be described in detail in combination with the accompanying Figures 1-3 The present application is further described in detail.

[0037] The embodiment of the present application discloses a shunt straw nozzle, referring to Figure 1 and Figure 2 , for setting in the end of the straw 1 for sucking, the shunt straw nozzle comprises two flow guide channels 2, referring to Figure 3 , the two flow guide channels 2 are arranged in parallel in the eight-character shape at the end of the straw 1 and are connected with the straw 1, and at the same time, the two flow guide channels 2 are provided with water stop valves, when the straw 1 is not used, the water stop valves close the straw 1 and the flow guide channels 2, the dust and impurities in the outside cannot enter the container to pollute the drinking liquid, and even if the liquid in the container is inverted, it will not flow out through the straw 1, when the user performs the sucking action, the liquid in the straw 1 flows to the flow guide channels 2 through the water stop valves and flows into the user's oral cavity.

[0038] It should be noted that the two V-shaped flow channels 2 divert and buffer the flowing liquid, and the outlets of the two flow channels 2 are staggered from the throat and flow to the sides of the user's mouth, making it difficult to cause splashing or choking, thus improving the user experience of the straw 1. In other embodiments, the number of flow channels 2 can be more than two, as long as the outlets of multiple flow channels 2 are not directly facing the throat and play a diversion and buffering role, thereby increasing the diversity of flow-diverting straw nozzles.

[0039] Reference Figure 2 and Figure 3 The included angle between the two guide channels 2 is set to a range of 15°-40°. Within this range, the included angle between the two guide channels 2 has a better diversion and buffering effect. In this embodiment, the included angle between the two guide channels 2 is selected as 25°.

[0040] Reference Figure 2 and Figure 3 The stop valve is a silicone stop valve 3, made of silicone material, which is safe, soft, and durable, and can deform to facilitate the opening and closing of the stop valve. The silicone stop valve 3 has a notch at its bottom. When the straw 1 is not in use, the silicone stop valve 3 is in its natural state, with the notch closed. When the user sucks, the notch opens. It should be noted that the notch of the silicone stop valve 3 can be straight, cross-shaped, or Y-shaped, as long as the deformation of the silicone stop valve 3 allows for opening and closing. In this embodiment, the silicone stop valve 3 is arc-shaped to improve the sealing of the notch in its natural state when the straw 1 is not in use. In other embodiments, the silicone stop valve 3 can also be other shapes, as long as the deformation of the silicone stop valve 3 allows for opening and closing of the notch.

[0041] Reference Figure 2 and Figure 3 The straw 1, located at the flow channel 2, is intended for the user to suck. Infants and young children are prone to biting and tearing this area. Therefore, the wall thickness of the straw 1 at the flow channel 2 is set to be greater than the wall thickness at other locations on the straw 1 to improve its lifespan and reduce the replacement cost of the split-flow straw nozzle. In addition, a positioning groove 4 is formed around the outer wall of the straw 1 at the flow channel 2 to position the user's lips or teeth, thereby improving the stability of the user's sucking action. Furthermore, the positioning groove 4 has a concave arc shape in its cross-section, which improves user comfort and further enhances the user experience of the straw 1.

[0042] Looking back Figure 1The installation seat 5 is fixedly sleeved on the outer wall of the straw 1, the straw 1 is connected to the container through the installation seat 5, so that the stability of the position of the straw 1 is improved. It should be noted that the part of the straw 1 above the installation seat 5 and the shunt straw nozzle are in the external air, and the part of the straw 1 below the installation seat 5 is in the container. At the same time, the installation seat 5 is fixedly provided with a gas return valve. When the straw 1 is not used, the gas return valve is in a closed state, the liquid in the container cannot flow out through the gas return valve, and the dust and other impurities in the external environment cannot enter the container to pollute the liquid. When the user performs the sucking action, the gas return valve is in a one-way open state, the external air flows into the straw 1 through the gas return valve, so as to balance the air pressure inside and outside the container, facilitate the user to perform the sucking operation for drinking operation, and prevent the straw 1 from being sucked and the liquid from being sprayed.

[0043] Similar to the silica gel water stop valve 3, the gas return valve is a silica gel gas return valve 6, and the bottom of the silica gel gas return valve 6 has a cutout. When the straw 1 is not used, the silica gel gas return valve 6 is in a natural state, at this time, the cutout of the silica gel gas return valve 6 is in a closed state. When the user performs the sucking action, the cutout of the silica gel gas return valve 6 is in an open state. Similarly, the cutout of the silica gel gas return valve 6 can be provided in a character type, a cross type or a Y type, as long as the deformation of the silica gel gas return valve 6 can realize the opening and closing of the cutout. In the embodiment, the bottom of the silica gel gas return valve 6 is provided in a hemispherical shape, so as to improve the sealing performance of the cutout of the silica gel gas return valve 6 in the natural state when the straw 1 is not used. In other embodiments, the silica gel gas return valve 6 can also be provided in other shapes, as long as the deformation of the silica gel gas return valve 6 can realize the opening and closing.

[0044] Referring to Figure 1 , the silica gel gas return valve 6, the installation seat 5 and the straw 1 are integrally formed, so as to improve the connection stability and structural strength between the silica gel gas return valve 6, the installation seat 5 and the straw 1, and facilitate processing.

[0045] The implementation principle of the shunt straw nozzle is as follows: when the straw 1 is not used, the silica gel water stop valve 3 and the silica gel air return valve 6 are in a natural state, the cutouts thereof are in a closed state, the liquid in the container cannot flow out through the silica gel water stop valve 3 and the silica gel air return valve 6, and the dust and impurities in the outside cannot enter the inside of the container through the silica gel water stop valve 3 and the silica gel air return valve 6; when the user performs a sucking action on the shunt straw 1 nozzle, due to the generation of air pressure difference, the silica gel water stop valve 3 and the silica gel air return valve 6 are deformed, at this time, the cutout of the silica gel water stop valve 3 and the cutout of the silica gel air return valve 6 are in an open state, the liquid in the container flows into the user's oral cavity through the straw 1 and the flow guide 2, the two flow guides 2 arranged in an eight-character shape perform shunt buffering on the flowing liquid, and the outlets of the two flow guides 2 are staggered with the position of the throat and flow to the two sides of the user's oral cavity, so that the phenomenon of splashing or choking is difficult to occur, thereby being beneficial to improve the use experience of the straw 1, and at the same time, the air in the outside flows into the container through the silica gel air return valve 6, so as to balance the air pressure inside and outside the container, facilitate the user to perform a sucking action for drinking operation, and be beneficial to prevent the problems of sucking the straw 1 flat, spraying liquid and the like.

[0046] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
