Description

Technical Field

[0001] The utility model relates to a nozzle, in particular to an anti-spray nozzle and bottles such as baby bottles, water bottles, and water cups using the nozzle. Background Art

[0002] For baby bottles and some water bottles, nozzles are used. There are different structural types for nozzles. Existing baby bottle nozzles are often straight tube structures, and the nozzles only have the function of sucking. For some water bottles or baby bottles, sliding lid or flip lid structures are adopted. When closed, the nozzle will be pressed and folded. When placed normally, the straw is directly accommodated in the lid. At this time, the nozzle is not restricted by other factors, but only bent due to the restriction of the cup lid. When the water temperature in the lid is high or the lid is tilted and inverted, the water in the bottle is likely to spray or leak from the nozzle. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides an anti-spray nozzle and a water cup.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An anti-spray nozzle includes a base. A through hole is provided in the base, and a straw is provided on the base. The straw is communicated with the through hole. A crease portion is provided on the outer side wall of the straw, and a convex portion is provided inside the straw, and the convex portion protrudes towards the crease portion.

[0006] As a further improvement, the convex portion is integrally formed on the inner side wall of the straw, and the convex portion and the crease portion are respectively located on both sides of the straw.

[0007] As a further improvement, the crease portion is provided at the lower part of the straw, and the crease portion divides the straw into a lower tube portion and an upper tube portion.

[0008] As a further improvement, a step surface is formed between the lower tube portion and the lower tube portion, and this step surface constitutes the crease portion.

[0009] As a further improvement, the straw is inclined towards the central axis of the through hole.

[0010] As a further improvement, a one-way valve is provided in the straw. After the straw is subjected to the extrusion force of external sucking or biting, the one-way valve opens, enabling the water inside the straw to flow outwards.

[0011] As a further improvement, the one-way valve is a V-shaped valve.

[0012] As a further improvement, the one-way valve is provided in the upper tube portion.

[0013] As a further improvement, the straw and the base are of an integrally formed structure.

[0014] A water cup, comprising a cup body and a spray-proof nozzle, and the base is installed and connected to the cup body.

[0015] Compared with the prior art, the utility model has the following beneficial technical effects:

[0016] By providing a crease portion on the outer side wall of the straw, the straw can be folded in a directional manner. Cooperating with the convex portion inside the straw, when the straw is folded by the cup lid, it bends towards the crease portion. After the straw is folded, the convex portion plays a sealing role, thus achieving a water sealing effect and preventing the water in the water cup from flowing out. Especially when encountering relatively high-temperature water, it can play a role in preventing water spraying. Moreover, with the degree of bending of the straw, the degree of blocking of the convex portion to the internal flow channel of the straw is also different, playing a role in controlling the water flow. Combined with the one-way valve inside the straw, it further plays a role in preventing water spraying and preventing water leakage. Description of the Drawings

[0021] The following details the embodiments of the present invention. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0022] In the description of the present invention, it should be understood that if there are terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, it is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the said features. In the description of the present invention, "a plurality" means two or more, unless otherwise specifically defined.

[0023] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection. It may be a mechanical connection or an electrical connection. It may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] As Figures 1-3 shown, a spray-proof nozzle includes a base 1. A through hole 3 is provided inside the base 1. A straw 2 is provided on the base 1. The straw 2 is communicated with the through hole 3. A crease portion 4 is provided on the outer side wall of the straw 2. A convex portion 5 is provided inside the straw 2. The convex portion 5 protrudes towards the crease portion 4. The straw 2 and the base 1 are of an integrally formed structure. For the specification size of the base, it can be determined according to the size of the water cup to which it needs to be assembled. Through the crease portion, the straw is bent in a specific direction. Taking the crease portion as the bending part, after the straw is pressed by an external force, it will bend along the set crease portion, with good directivity and better bending effect. When the straw is not completely folded, the convex portion does not completely block the internal channel of the straw. Moreover, as the degree of folding of the straw is different, the blocking opening degree of the convex portion is also different, thus forming a water control effect.

[0025] The convex portion 5 is integrally formed on the inner side wall of the straw 2. The convex portion 5 and the crease portion 4 are respectively located on both sides of the straw 2. The convex portion 5 protrudes towards the center inside the straw 2.

[0026] The crease part 4 is arranged at the lower part of the straw 2, and the crease part 4 divides the straw 2 into a lower tube part 21 and an upper tube part 22. A stepped surface is formed between the lower tube part 21 and the lower tube part 22, and this stepped surface constitutes the crease part. In the natural state, the straw will be in an inclined state and is inclined towards the crease part side. When folding the straw, it is not easy to cause misoperation, ensuring that the straw is folded towards the correct side.

[0027] A one-way valve 6 is arranged inside the upper part of the straw 2. When the straw 2 is subjected to the extrusion force of external sucking or biting, the one-way valve 6 opens, enabling the water inside the straw to flow outwards. The one-way valve is a V-shaped valve. When the straw is not subjected to external force, the one-way valve remains closed, and at this time, it is relatively difficult for the water inside to flow out. When encountering relatively high-temperature water, due to the increased pressure, there is a probability of flushing open the one-way valve. Combining with the function of the convex part, a complete water sealing and anti-water spraying effect can be achieved. When the user sucks or bites the straw, the straw is subjected to the extrusion force, and the V-shaped valve also opens correspondingly. At this time, the water inside the straw can flow out normally.

[0028] A water cup includes a cup body and an anti-spraying nozzle, and the base is installed and connected to the cup body. The base can be installed with the cup body by means of a buckle or a thread. When the cup cover is closed, the straw will be folded. When the straw is folded close to horizontally, at this time, the convex part completely blocks the internal channel of the straw, forming a water sealing effect. In the natural state, the one-way valve is used to seal the water. As the straw is bent to different degrees, the size of the blockage of the convex part to the inside of the straw is different, that is, the opening degree is different, forming a water control effect.

[0029] It should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
