Description

Technical Field

[0001] The present application relates to the field of straws, and in particular to a straw tip. Background Art

[0002] Straws are used to absorb liquid from a container. Existing straight-through straws, when hot water is loaded into the container, create a pressure difference between the container and the outside world, causing the pressure inside the cup to be greater than outside. This pressure causes liquid to splash out of the straw. Children tend to bite on straws, and this can cause the inner wall of straight-through straws to stick together, making it difficult to absorb water.

[0003] In order to solve the splashing problem, a valve is installed inside the existing straw. However, in actual use, when biting open the straw with a valve, since the thickness of the straw wall at the biting part is the same, there is no obvious change in the biting force from the time the valve is opened to the time the inner wall of the straw is bitten. The user cannot control the biting force and therefore cannot identify the state of the bite. Therefore, when using it, the user will habitually increase the biting force to increase the opening of the valve.

[0004] However, this method often causes the inner wall of the straw to cling too tightly to the container due to excessive biting, making it difficult for the straw to absorb liquids. Furthermore, for straws with valves with a wall thickness of 0.5 mm or less, the deformation range of the wall along the length of the straw is relatively small when the user bites to open the valve. Therefore, the user needs to bite the valve in a fixed position, which is inconvenient. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the present application provides a straw assembly and a straw head.

[0006] The present application provides a straw assembly, which adopts the following technical solution:

[0007] A straw assembly comprises a tube body and a bite block arranged on the outer wall of the tube body. A channel with two ends open is formed in the tube body. The bite block is used to prevent a user from biting excessively.

[0008] By adopting the above technical solution, a channel is formed on the tube body, which can be used for liquid to flow out and can also be used in combination with a straw. The bite block is used to prevent the user from excessively biting the tube body, ensuring that the inner wall of the tube body is not too close to the inner wall, leaving space for liquid circulation; the bite block increases the service life of the tube body and can effectively delay the breakage of the tube body due to biting.

[0009] This application also provides a pipette tip, which adopts the following technical solution:

[0010] A pipette head comprises a pipette head, a control valve arranged in the pipette head, a plurality of reinforcing ribs arranged on the inner wall of the pipette head and the above-mentioned pipette assembly arranged on the pipette head, wherein the reinforcing ribs are arranged along the length direction of the pipe head and are used to extend the bite range of the control valve.

[0011] By adopting the above technical solution, the tube head is used to connect with various straw bases and various angles of connection. The control valve is used to prevent liquid leakage when the straw is not in use. The reinforcement ribs increase the service life of the tube head. The reinforcement ribs also facilitate increasing the user's bite range to control the opening of the control valve. The straw assembly increases the service life of the tube head, prevents the user from over-biting the tube head, and ensures that the channel inside the tube head remains unobstructed.

[0012] Preferably, the straw assembly comprises a tube body and a bite block arranged on the outer wall of the tube body, and the tube body is sleeved on the tube head.

[0013] By adopting the above technical solution, the tube body is sleeved on the tube head, and the straw assembly can be detachably installed on the tube head, which is convenient for users to use different types of straws and prolongs the service life of the straws.

[0014] Preferably, the straw assembly comprises a tube body and a bite block arranged on the outer wall of the tube body, and the tube body and the tube head are integrally formed.

[0015] By adopting the above technical solution, the tube body and the tube head are integrally formed, thereby improving the connection strength between the straw assembly and the tube head.

[0016] To sum up, the bite block of the present application effectively prevents excessive biting of the pipe body, effectively prevents the inner wall of the pipe head from sticking, effectively prevents the pipe body from breaking due to biting, and extends the service life of the pipe body; the reinforcing ribs increase the strength of the pipe head and improve the user's control over the control valve.

[0036] The following is combined with Figures 1-18 This application is described in further detail.

[0037] Example 1:

[0038] The present application discloses a straw assembly. Figure 1 and Figure 2 , including a tube body 1 and a bite block 2 provided on the outer wall of the tube body 1. In the embodiment of the present application, the tube body 1 and the bite block 2 are integrally formed to improve the connection stability of the tube body 1 and the bite block 2. A channel 3 with both ends open is formed in the tube body 1. The bite block 2 is used to prevent the user from over-biting. After the user bites the tube body 1 and fits it into the bite block 2, the bite force increases significantly, and it is not appropriate to continue biting. The bite block 2 plays a stable state of bite support. The inner wall of the tube body 1 is not too close to the fit, leaving space for liquid circulation. Generally, the bite block 2 is provided on the side of the tube body 1 along the circumferential direction. The bite block 2 on the side of the tube body 1 can also be provided as two or more blocks spaced apart in the upper and lower directions. In this embodiment, one bite block 2 is provided on each side of the side of the tube body 1 along the bite direction. The tube body 1 can be integrally formed with the straw or sleeved on the head of the straw to facilitate the user to use the straw.

[0039] Reference Figure 1 In the embodiment of the present application, the bite block 2 is integrally formed with the tube body 1. The bite block 2 is fixedly mounted on the outer wall of the tube body 1 and extends along the length of the tube body 1, making it easy for the user to clearly define the bite range, effectively preventing the tube body 1 from breaking due to frequent biting, and extending the service life of the straw.

[0040] The straw assembly of the present invention is implemented as follows: the user can place the assembly over the straw to prevent the user from over-biting the straw, preventing the straw from clinging to the wall, and ensuring normal use of the straw. When the assembly is integrally formed with the straw, the assembly is located at the outlet end of the straw. When the user bites the straw, the bite block 2 contacts the bite block 2, which prevents the user from over-biting the straw. At the same time, the tube body 1 strengthens the straw tip 4, reducing the degree of deformation of the straw when bitten, effectively preventing the straw from breaking due to repeated biting, and extending the use of the straw.

[0041] Example 2:

[0042] The difference between the embodiment of the present application and the embodiment 1 is that: Figure 3 The bite block 2 is handle-shaped or C-shaped, and a deformation space is formed between the bite block 2 and the tube body 1, which further expands the bite deformation range and reduces the effect of excessive bite by the user.

[0043] Example 3:

[0044] The present application embodiment discloses a pipette tip. Figure 4 and Figure 5 , including a tube head 4, a control valve 5 installed in the tube head 4, a reinforcing rib 6 installed on the inner wall of the tube head 4 and arranged along the length direction of the tube head 4, and a straw assembly arranged on the tube head 4. The straw assembly includes a tube body 1 and a bite block 2 arranged on the outer wall of the tube body 1. The tube body 1 is integrally formed with the tube head 4 in the embodiment of the present application. The reinforcing rib 6 is generally placed at the rear end of the control valve 5. In actual use, the control valve 5 can also be placed at the front end. The reinforcing rib 6 can also be a slight protrusion on the outer wall of the tube body 1. When the wall of the straw is thin, the reinforcing rib 6 is used to extend the bite range of the control valve 5. When the user bites the position where the reinforcing rib 6 is located, it can effectively drive the opening and closing of the control valve 5. At the same time, the reinforcing rib 6 effectively improves the strength of the bite position of the tube head 4, extends the use time of the tube head 4, and increases the degree of deformation of the tube head 4 along the length direction.

[0045] During the implementation process, the tube body 1 can also be sleeved on the tube head 4, and the diameter of the tube body 1 gradually decreases. The tube body 1 is sleeved on the tube head 4 to lock the reduced inner diameter of the tube head 4; or limit movement and limit rotation slots are set at both ends of the tube body 1; or an embedded groove is provided on the inner wall of the tube body 1, and an embedded block matching the embedded groove is provided on the tube head 4, and the tube body 1 and the tube head 4 are fixed by the embedded groove and the embedded block.

[0046] Reference Figure 6 、 Figure 7 and Figure 8 The straw assembly is integrally formed with the pipe head 4, which is in a straight-through state. The control valve 5 is a convex valve 51 or a flat valve 52. The convex valve 51 is V-shaped, and the spacing between the two sides of the convex valve 51 gradually decreases as it moves away from the water outlet of the pipe head 4. A control slit 7 is defined at the lowest end of the convex valve 51. When the user bites the pipe body 1, the pipe body 1 squeezes the control valve 5, deforming it and causing the control slit 7 to open, allowing liquid to be absorbed. When the user bites into the bite block 2, the bite force increases significantly, making it difficult to continue biting. The inner wall of the pipe body is not too close to the pipe body, leaving space for liquid to flow. The control slit 7 is in an optimal opening state, facilitating liquid flow.

[0047] Reference Figure 8 A control slit 7 is also provided on the flat valve 52. When the user bites the tube body 1, the inner wall of the tube head 4 is deformed, which in turn causes the flat valve 52 to deform. The deformation of the flat valve 52 drives the control slit 7 to open, facilitating the outflow of liquid. The flat valve 52 can also absorb liquid by increasing the suction force to allow the liquid to pass through the control slit 7.

[0048] Example 4:

[0049] The difference between the embodiment of the present application and the third embodiment is that, Figure 9 、 Figure 10 and Figure 11The bite block 2 is handle-shaped or C-shaped, and a deformation space is formed between the bite block 2 and the tube body 1; and the tube body 1 and the tube head 4 are integrally formed, and the side walls of the tube body 1 and the tube head 4 can also be provided with a gap, which is located in the deformation space and is used to expand the liquid outflow path.

[0050] Embodiment 5:

[0051] The difference between the embodiment of the present application and the third embodiment is that, Figure 12-16 The water outlet of the pipe head 4 is provided with a bent wall 8, and a deflected water outlet 9 is formed between the bent wall 8 and the side wall of the pipe head 4. The deflected water outlet 9 is used to guide the liquid to change the flow direction and prevent the liquid from rushing directly into the throat.

[0052] Example 6:

[0053] The difference between the embodiment of the present application and the fifth embodiment is that, Figure 17 and Figure 18 The tube body 1 and the tube head 4 are integrally formed, and gaps are provided on the side walls of the tube body 1 and the tube head 4 to expand the liquid outflow path.

[0054] In the absence of conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.

[0055] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
