Abstract
Description
Technical Field
[0001] This application relates to the field of straws, and in particular to a straw tip that prevents spraying, choking, and sticking Background Art
[0002] In order to facilitate the adsorption of the liquid in the container, people use straws to adsorb the liquid in the container. The following problems will occur when using existing straws: 1. When the straw is inserted into the container, due to the air pressure difference between the inside and outside of the cup when it is hot water, the pressure inside the cup is greater than the outside, and under the action of the pressure, the liquid will splash out from the straw; 2. When the user uses a straw with a valve that is opened by biting, since the thickness of the straw wall at the biting part is the same, from the opening of the biting valve to the fitting of the inner wall of the biting straw, the biting force does not change significantly, and the state during biting cannot be identified. Therefore, when slightly increasing the biting force to increase the opening of the valve during use, the inner wall of the straw often gets too close and fits due to excessive biting, resulting in the inconvenience of the straw to adsorb the liquid in the container; 3. The water outlet of the straight-through straw is directly facing the throat. When the user sucks too hard, a large amount of liquid rushes directly into the throat, which is likely to choke the user. When using a straight-through straw with a valve in the lying position, the water flowing out from the straight-through opening will directly flow to the throat at the lower point, posing a risk of choking on water. Summary of the Utility Model
[0003] In order to solve the problems existing in the prior art, this application provides a straw tip that prevents spraying, choking, and sticking
[0004] A straw tip that prevents spraying, choking, and sticking provided by this application adopts the following technical solutions:
[0005] A straw tip that prevents spraying, choking, and sticking includes a tube body, a bending wall provided at the water outlet end of the tube body, and a biting valve provided in the tube body. The tube body includes a fixing part at the water inlet end, a first positioning part provided at the water outlet end of the fixing part, a deformation part provided at the water outlet end of the first positioning part, and a second positioning part provided at the water outlet end of the deformation part. The thickness of the deformation part is smaller than the thickness of the first positioning part and / or the second positioning part. The bending wall is located at the water outlet end of the second positioning part, and a deflection water outlet for the side water outlet of the liquid is formed between the bending wall and the second positioning part. The biting valve is located in the deformation part, and an opening slit is provided on the biting valve.
[0006] By adopting the above technical solutions, the bending wall is used to guide the liquid to flow obliquely, preventing the liquid from directly flowing into the throat and reducing the risk of choking the user; the fixing part is used to be inserted into the container. The thicknesses of the first positioning part and the second positioning part are thicker than that of the deformation part, which is convenient for the user to bite the deformation part to cause deformation and control the opening of the slit on the biting valve. The biting valve is convenient for the user to control the flow and blockage of the liquid in the tube body, and the deflection water outlet is for the liquid to flow out obliquely.
[0007] Preferably, a fitting member is provided on the pipe body, and the fitting member is used to prevent the pipe wall of the pipe body from being overly close.
[0008] Preferably, the fitting member includes a fitting block provided on the pipe wall of the pipe body.
[0009] In summary, the thickness of the deformation part is smaller than the thicknesses of the first positioning part and the second positioning part, which is convenient for the user to bite the deformation part, reduces the biting force of the user, and facilitates the user to control the opening and closing of the bite valve; the thickness of the deformation part is smaller than the thicknesses of the first positioning part and the second positioning part, and the deformation part is arranged between the first positioning part and the second positioning part, which is convenient for the deformation part to bite and deform. At the same time, when over-biting occurs, the two ends of the deformed deformation part are pulled, so that the biting force is significantly increased and it is not suitable to continue biting in a stable state, thereby preventing over-biting the pipe wall; the bending wall and the water outlet bias are used to control the liquid flow direction, guide the liquid to deviate from the throat position, and reduce the risk of choking for the user.

Detailed description of the specific implementation
[0028] The following further elaborates on the present application in conjunction with the attached Figures 1 - 17 for a more detailed description of the present application.
[0029] Embodiment 1:
[0030] The embodiment of the present application discloses an anti - spraying, anti - choking and anti - sticking sealing straw head. Referring to Figure 1 and Figure 2 , it includes a pipe body 1, a bending wall 2 provided at the water outlet end of the pipe body 1, and a bite valve 3 provided inside the pipe body 1. In the embodiment of the present application, the pipe body 1, the bending wall 2 and the bite valve 3 are integrally formed, improving the connection stability between each structure. The bending wall 2 is used to block the direct water outlet end of the pipe body 1 and guide the liquid to move away from the throat. A biased water outlet 4 for lateral water outlet of the liquid is formed between the bending wall 2 and the pipe body 1. The bite valve 3 is provided with an opening slit 7. When the user bites the pipe body 1, the pipe wall of the pipe body 1 deforms and the opening slit 7 opens, facilitating the outflow of the liquid from the pipe body 1.
[0031] Referring to Figure 1 and Figure 2, To facilitate the user to bite the tube body 1, the tube body 1 includes a fixed part 11, a first positioning part 12, a deformation part 13, and a second positioning part 14 arranged in sequence along the length direction. The fixed part 11 is located at the water inlet end of the tube body 1, the second positioning part 14 is located at the water outlet end of the tube body 1, and the deviation water outlet 4 is located between the second positioning part 14 and the bending wall 2. To facilitate the user to bite the tube body 1 and control the deformation of the bite valve 3. The thickness of the deformation part 13 is smaller than that of the first positioning part 12, and the thickness of the deformation part 13 is smaller than that of the second positioning part 14. The deformation part 13 has a thinner thickness, which is convenient for the user to bite the tube body 1, drive the bite valve 3 to deform, and then drive the opening slit 7 to open, facilitating the user to control the tube body 1 to adsorb liquid.
[0032] Refer to Figure 1 and Figure 2 , In the embodiment of the present application, the bite valve 3 is a convex valve 31 or a flat valve 32, and the cross-sectional shape of the convex valve 31 is V-shaped. When the tube body 1 is not in use, when the liquid flows to the convex valve 31, the liquid will squeeze the side walls on both sides of the convex valve 31 to be close, further improving the tightness of the opening slit 7 and reducing the possibility of liquid leakage.
[0033] Refer to Figure 3 and Figure 4 , When the bite valve 3 is a flat valve 32, the user bites the deformation part 13, the flat valve 32 deforms, and the opening slit 7 opens.
[0034] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , In the embodiment of the present application, the inner wall of the deformation part 13 is vertically arranged, and the outer wall of the deformation part 13 can be recessed towards the inside of the tube, facilitating the user to bite the tube body 1. The recess is convenient for bite positioning and facilitates the deformation of the tube body 1. A groove 6 is provided on the inner wall of the tube body 1 along the length direction, and the groove 6 is located on the first positioning part 12. The groove 6 can ensure that there is no step difference in the inner channel of the tube body 1 and no liquid remains.
[0035] The implementation principle of an anti-spray, anti-choking, and anti-sticking sealing straw head in the embodiment of the present application is as follows: The user bites the deformation part 13. The deformation part 13 has a thinner thickness, which is convenient for controlling the deformation to open the bite valve 3. At the same time, the first positioning part 12 and the second positioning part 14 have a thicker thickness, which can effectively pull the deformation part 13 and reduce the possibility of the user biting the tube body 1 excessively. The bending wall 2 is used to guide the liquid to change the flow direction and flow out from the deviation water outlet 4 that deviates from the throat part, reducing the risk of the user choking on water.
[0036] Embodiment 2:
[0037] The difference between the embodiment of the present application and Embodiment 1 is: Refer to Figure 5 , Figure 6 and Figure 7, the deformation part 13 protrudes towards the outside of the pipe body 1, which is used to expand the deformation range of the deformation part 13, facilitating the user to bite the deformation part 13 to control the opening and closing of the bite valve 3.
[0038] Embodiment Three:
[0039] The difference between the embodiment of the present application and Embodiment One lies in: referring to Figure 8 and Figure 9 , the deformation part 13 is recessed towards the inside of the pipe body 1, facilitating the user to bite the pipe body 1. In order to increase the liquid outflow volume, slits can be provided on the deformation part 13. When the user bites the deformation part 13, the slits open, and the liquid can flow out from the slits. The slits are located on the side wall of the pipe body 1, effectively reducing the possibility that the liquid is aligned with the throat and causing the user to choke on water, and increasing the water output of the pipe body.
[0040] Embodiment Four:
[0041] The difference between the embodiment of the present application and Embodiment Three lies in: referring to Figure 10 and Figure 11 , a fitting member 5 is provided on the pipe body 1. The fitting member 5 is used to prevent the pipe wall of the pipe body 1 from being overly fitted. The fitting member 5 includes a fitting block 51 provided on the pipe wall of the pipe body 1. In the embodiment of the present application, the fitting block 51 is in the shape of a handle or an arc or a C shape, mainly used to avoid the slits and at the same time facilitate the user to bite.
[0042] Embodiment Five:
[0043] The difference between the embodiment of the present application and Embodiment One lies in: referring to Figure 12 , Figure 13 and Figure 14 , a fitting member 5 is provided on the pipe body 1. The fitting member 5 is used to prevent the pipe wall of the pipe body 1 from being overly fitted. The fitting member 5 includes a fitting block 51 provided on the pipe wall of the pipe body 1. The fitting block 51 is within the range of the deformation part 13 and is used to prevent the user from overly biting the pipe body 1, facilitating the user to suck the liquid.
[0044] Embodiment Six:
[0045] The difference between the embodiment of the present application and Embodiment One lies in: referring to Figure 15 , Figure 16 and Figure 17 , the fitting block 51 is in the shape of a handle or an arc or a C shape in the embodiment of the present application, facilitating the user to bite the pipe body 1, facilitating bite deformation, and at the same time playing a role in preventing the user from overly biting the pipe body 1.
[0046] In the case of no conflict, the embodiments and the features in the embodiments can be combined with each other. During the actual use of the straw tip disclosed in this application, it can be integrally formed and connected to bases of various structures. With various angle settings, the straw tip and the straw base can be installed forward from the plug hole of the container plug and the assembly end of the container, or can be set to be inserted into the straw base reversely from the plug hole at the other end of the container plug.
[0047] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
