Description

Technical Field

[0001] The utility model relates to the technical field of water cups, in particular to a blowout prevention valve and a cup cover thereof. Background Art

[0002] The straw cup is a commonly used drinking cup. When the straw cup is filled with hot water and the user drinks water through the straw, the hot water is easy to spray out from the straw and even scald the user, causing inconvenience to the user. Improvements are needed in this regard. Summary of the invention

[0003] The utility model aims to solve the defects in the prior art that hot water is easily sprayed out from a straw when drinking hot water, thus causing inconvenience to the user, and provides a new anti-spray valve and a cup cover thereof.

[0004] In order to solve the above technical problems, the utility model is implemented through the following technical solutions:

[0005] A blowout preventer valve comprises a main body, a connecting pipe and a steel ball, wherein a first channel and a water inlet are provided at both ends of the main body, the first channel is communicated with the water inlet, a second channel passes through the connecting pipe, the connecting pipe is arranged on the main body and the first channel is communicated with the second channel; the outer diameter of the steel ball is greater than the maximum width of the water inlet and the second channel, the steel ball is movably arranged in the first channel and controls the opening and closing of the water inlet and the second channel.

[0006] When the blowout preventer is installed on the straw and the user drinks water through the straw, the water flows into the first channel from the water inlet under the suction force and flows out from the second channel. The steel ball moves up first and covers one end of the second channel, so that the water flow is dispersed when encountering the steel ball, reducing the outflow force of the water flow, realizing the blowout preventer function of the straw, preventing the user from being scalded when drinking hot water, and improving the user's comfort when using it.

[0007] Preferably, in the above-mentioned blowout preventer, the number of the connecting pipe is one, and one end of the connecting pipe is inserted into the first channel and bonded to the main body.

[0008] The connecting pipe is plugged and matched with the first channel and bonded with the main body, which facilitates the placement of the steel ball in the first channel and improves the simplicity of assembling the blowout preventer.

[0009] Preferably, in the above-mentioned blowout preventer, the end of the connecting pipe is provided with a clearance surface, and the upper end of the clearance surface is inclined inwardly along the height direction.

[0010] The provision of the relief surface reduces the width of the end of the connecting tube, making it easier to insert and assemble the connecting tube on the straw.

[0011] Preferably, a hemispherical groove connected to the second channel is formed at the end of the connecting tube, the hemispherical groove is located in the first channel, the hemispherical groove and the second channel are coaxially arranged, and the hemispherical groove is adapted to the shape of the steel ball.

[0012] The hemispherical groove allows the steel ball to cover the second channel more closely, thereby improving the anti-splashing effect of the blowout preventer.

[0013] Preferably, in the above-mentioned blowout preventer, a positioning disc is provided on the outer side wall of the connecting pipe, the positioning disc is coaxially arranged with the connecting pipe, the outer diameter of the positioning disc is consistent with the outer diameter of the main body, and the positioning disc abuts against the end of the main body.

[0014] Because the outer diameter of the positioning disc is consistent with the outer diameter of the main body, on the one hand, the depth of the end of the connecting pipe inserted into the first channel is limited, which facilitates the assembly of the connecting pipe and the main body, and on the other hand, improves the aesthetics of the blowout preventer.

[0015] Preferably, in the above-mentioned blowout preventer, a plurality of protrusions are arranged at the bottom of the first channel, and the protrusions are circumferentially arranged outside the water inlet.

[0016] The setting of the protrusion increases the gap between the steel ball and the water inlet, which not only prevents the steel ball from blocking the outflow of water when it falls to the bottom of the first channel, but also makes it easier for users to absorb water.

[0017] Preferably, in the above-mentioned blowout preventer, an extension pipe is provided at the end of the main body, the extension pipe has the same structure as the connecting pipe, and the extension pipe is coaxially arranged with the main body and connected to the water inlet.

[0018] The provision of the extension pipe increases the installation structure when the blowout preventer is assembled with the suction pipe, thereby increasing the diversity of the blowout preventer and making it suitable for different suction pipes.

[0019] A cup cover comprises a cover body, a straw arranged on the cover body and the anti-spray valve, wherein one end of the connecting pipe away from the main body is inserted into the straw and plugged in.

[0020] The blowout preventer valve and the suction pipe are detachably connected by plug-in matching, which has the advantages of simple structure, convenient assembly, and easy cleaning of the blowout preventer valve and the suction pipe.

[0021] A cup cover comprises a cover body, a straw arranged on the cover body and the anti-spray valve, wherein the straw comprises a first section and a second section, an end of the connecting pipe away from the main body is inserted into the tail of the first section and plugged in, and the extension pipe is inserted into the head of the second section and plugged in.

[0022] The blowout preventer can be installed between the straws through the extension pipe and the connecting pipe, which improves the stability of the blowout preventer installed on the straw, and also increases the assembly methods and positions between the blowout preventer and the straw, increasing the diversity of the product and being able to meet the various needs of users.

[0033] Preferably, the number of the connecting tube 2 is one, and one end of the connecting tube 2 is inserted into the first channel 11 and bonded to the main body 1 .

[0034] Preferably, a clearance surface 22 is provided at the end of the connecting pipe 2, and the upper end of the clearance surface 22 is inclined inwardly along the height direction.

[0035] Preferably, a hemispherical groove 23 connected to the second channel 21 is formed at the end of the connecting tube 2 , the hemispherical groove 23 is located in the first channel 11 , the hemispherical groove 23 and the second channel 21 are coaxially arranged, and the hemispherical groove 23 is adapted to the shape of the steel ball 3 .

[0036] Preferably, a positioning disc 4 is provided on the outer wall of the connecting tube 2 , the positioning disc 4 is coaxially arranged with the connecting tube 2 , the outer diameter of the positioning disc 4 is consistent with the outer diameter of the main body 1 , and the positioning disc 4 abuts against the end of the main body 1 .

[0037] Preferably, a plurality of protrusions 5 are disposed at the bottom of the first channel 11 , and the protrusions 5 are circumferentially arranged outside the water inlet 12 .

[0038] Specifically, in the embodiment of the present application, the main body 1 is cylindrical, the relief surface 22 and the hemispherical groove 23 are distributed at both ends of the connecting pipe 2, and the positioning disc 4 is distributed on the outer side wall of the connecting pipe 2 close to the hemispherical groove 23. When assembling the blowout preventer, the steel ball 3 is first placed in the first channel 11, and then the end of the connecting pipe 2 provided with the hemispherical groove 23 is inserted into the first channel 11, and then the positioning disc 4 is bonded to the main body 1, and the assembly of the blowout preventer is completed.

[0039] The protrusions 5 are rectangular and distributed along the diameter direction of the first channel 11. There are 8 protrusions 5 and they are circumferentially distributed around the water inlet 12, so that there is a certain gap between the steel ball 3 and the water inlet 12, which is convenient for users to absorb water.

[0040] Example 2

[0041] Preferably, an extension tube 6 is provided at the end of the main body 1 , the extension tube 6 has the same structure as the connecting tube 2 , and the extension tube 6 is coaxially arranged with the main body 1 and communicated with the water inlet 12 .
