Description

Technical Field

[0001] The present invention relates to the technical field of cups, and particularly to a cup with exhaust and pressure relief functions.

Background Art

[0002] A cup is an indispensable item in people's daily life. A conventional cup generally consists of a cup body and a cup lid. When hot water is put into the cup body, the air inside expands and the internal pressure rises. Due to the pressure difference between the inside and outside, if the cup lid is opened in this state, the hot water will spurt out, causing serious safety hazards to the user, such as getting burned.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Currently, the commercially available cups have a structure in which an exhaust hole is directly provided in the cup lid, and the gas in the cup body is directly discharged from the exhaust hole. Although this can avoid the pressure increase in the cup body, there is a phenomenon of water leakage because it cannot be sealed during the use process, which is inconvenient for users to carry. Therefore, there is room for further improvement in the prior art.

Means for Solving the Problems

[0004] In view of the above problems of the prior art, an object of the present invention is to provide a cup with exhaust and pressure relief functions.

[0005] To achieve the above object, the present invention provides the following technical solutions. The present invention provides a cup with exhaust and pressure relief functions, including a cup body and a cup lid mounted on the upper end of the cup body. An exhaust port and a water passage port communicating with the inside of the cup body are provided on the cup lid. The cup further includes a water intake pipe, and the water intake pipe is movably provided on the cup lid. When the water intake pipe is in the first position, both the exhaust port and the water inlet are sealed. When the water intake pipe moves from the first position to the second position, the exhaust port is in an open state. When the intake pipe moves from the second position to the third position, the intake pipe and the water inlet become connected.

[0006] Furthermore, the water intake pipe is rotatably mounted on the cup lid, and by rotating the water intake pipe, it is possible to switch between the first, second, and third positions of the water intake pipe.

[0007] Furthermore, the cup lid is provided with a movable window, the movable window includes a bottom wall and an upper wall, the water intake pipe is rotatably connected to the bottom wall and / or the upper wall, and the exhaust port is located in the bottom wall and is provided facing the upper wall.

[0008] Furthermore, the rotation angle of the water intake pipe is between 0 and 180 degrees.

[0009] Furthermore, when the intake pipe is in the first position, it is housed inside the movable window. When the intake pipe moves from the first position to the second or third position, one end of the intake pipe rotates from inside the movable window to outside the movable window.

[0010] Furthermore, the intake pipe includes a main body and a pipe section and a connecting section connected to the main body. The main body is rotatably connected to the cup lid via the connecting section, and the main body is provided with a first through hole and a first sealing section. The first through hole is used to connect the pipe section and the water inlet, and the first sealing section is used to seal the water inlet.

[0011] Furthermore, the main body is provided with a second through-hole and a second sealing portion. The second through-hole is used to connect to the exhaust port, and the second sealing portion is used to seal the exhaust port.

[0012] Furthermore, the first through hole, the second through hole, the first sealing portion, and the second sealing portion are installed at annular intervals along the central axis of the connecting portion.

[0013] Furthermore, the cup further includes an elastic sealing structure, the elastic sealing structure is provided at the exhaust port, When the intake pipe is in the first position, the pipe section applies force to the elastic sealing structure, and the elastic sealing structure seals the exhaust port. When the water intake pipe moves from the first position to the second position, the pipe releases the force acting on the elastic sealing structure, and the elastic sealing structure opens the exhaust port.

[0014] Furthermore, the elastic sealing structure further includes a sealing member and an elastic member, the sealing member being attached to the exhaust port, and the pipe applying force to the sealing member, thereby sealing the exhaust port and causing the elastic member to store energy. When the pipe releases the force acting on the sealing member, the elastic member returns to its original position, moving the sealing member upward and opening the exhaust port.

[0015] Furthermore, the cup further includes a fan structure, the fan structure being rotatably mounted on the cup lid. The fan structure includes a bracket, a drive structure, and blades. The bracket is rotatably connected to the cup lid, and the drive structure is connected to the blades and drives them to rotate. The bracket is provided with an intake port and an exhaust port that communicate with the blades.

[0016] The beneficial effects of the technical solution of the present invention are as follows: The cup of the present invention is provided with an exhaust port and a water passage port communicating with the inside of the cup body on the cup lid, and a movable water intake pipe is installed on the cup lid. When the user needs to take water, first move the water intake pipe from the first position to the second position to open the exhaust port, release pressure and exhaust, and then move the water intake pipe from the second position to the third position to communicate the water intake pipe with the water passage port. This can avoid unexpected injuries to the user caused by the ejection of hot water. Furthermore, the user can always move the water intake pipe to the first position to seal the exhaust port and the water passage port simultaneously to prevent water leakage, improving the convenience when the user carries it.

[Modes for carrying out the invention]

[0018] Hereinafter, the technical solutions in embodiments of the present invention will be clearly and completely described with reference to the drawings relating to embodiments of the present invention. Clearly, the specific embodiments described herein are for interpretation purposes only and do not limit the present invention. All other embodiments that can be obtained without creative work by those skilled in the art based on embodiments of the present invention are all within the scope of the protection of the present invention.

[0019] In the embodiments of the present invention, all direction indicators (e.g., up, down, left, right, front, back, etc.) are used solely to interpret the relative positional relationships and operating states between each component in a specific orientation (e.g., the orientation shown in the drawings). If the specific orientation changes, the direction indicators will also change accordingly.

[0020] In this invention, unless otherwise explicitly stated or limited, terms such as "connection" and "fixed" should be interpreted broadly. For example, "connection" 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 a direct connection or an indirect connection via an intermediate medium. It may be internal communication between two parts or an interaction relationship between two parts. Unless otherwise explicitly limited, those skilled in the art will be able to understand the specific meaning of the above terms in this invention depending on the specific situation.

[0021] Furthermore, in this invention, descriptions such as "first," "second," etc., are used solely for explanatory purposes and should not be understood as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, features limited by "first," "second," etc., may explicitly or implicitly include at least one such feature.

[0022] Please refer to Figures 1 to 6. The present invention provides a cup 100 with exhaust and pressure release functions, which includes a cup body 10 and a cup lid 20 attached to the upper end of the cup body 10. The cup body 10 of the present invention can preferably employ a double-insulated structure to prevent burns to the user. A handle string 12 is provided on the outside of the cup body 10 for the user's convenience in carrying it.

[0023] Here, the cup lid 20 is provided with an exhaust port 21 and a water inlet 22 that communicate with the inside of the cup body 10.

[0024] The cup 100 further includes a water intake pipe 30, which is movably mounted on the cup lid 20.

[0025] In this embodiment, the water intake pipe 30 can move between the first position, the second position and the third position.

[0026] When the water intake pipe 30 is in the first position, both the exhaust port 21 and the water inlet 22 are sealed, which avoids the problem of water leakage and improves the portability and convenience for the user.

[0027] When the water intake pipe 30 moves from the first position to the second position, the exhaust port 21 is open, and at the same time, the water passage port 22 is sealed. At this time, the gas inside the cup body 10 is discharged through the exhaust port 21, and the air pressure inside and outside the cup body 10 can be effectively equalized, thereby preventing accidental injury to the user due to the ejection of hot water from inside the cup body 10.

[0028] When the water intake pipe 30 moves from the second position to the third position, the water intake pipe 30 and the water inlet 22 become connected, and the user can take in water through the water intake pipe 30.

[0029] When a user needs to take in water, they can first move the intake pipe 30 from the first position to the second position to open the exhaust port 21, thereby releasing pressure and exhausting the water. After that, they can move the intake pipe 30 from the second position to the third position to connect the intake pipe 30 with the water inlet 22. This prevents accidental injury to the user due to the ejection of hot water. In addition, the user can move the intake pipe 30 back to the first position at any time to seal the exhaust port 21 and the water inlet 22 simultaneously, preventing water leakage and making it convenient for the user to carry.

[0030] In one embodiment, the water intake pipe 30 is rotatably mounted on the cup lid 20, and by rotating the water intake pipe 30, it is possible to switch between the first, second, and third positions of the water intake pipe 30, making it easy for the user to operate.

[0031] Of course, the water intake pipe 30 is not limited to being rotatably mounted on the cup lid 20, but may also be mounted on the cup lid 20 so as to be linearly movable (for example, in a straight line). It is not limited to these, and users can configure it specifically according to their actual needs.

[0032] In this embodiment, the rotation angle of the water intake pipe 30 is preferably 0 to 180 degrees. For example, when the water intake pipe 30 is rotated 10 degrees, the exhaust port 21 is opened, and when the water intake pipe 30 is rotated 31 degrees, the water inlet is opened. In other words, the rotation angle of the water intake pipe 30 can be set to be very small, thereby reducing the space occupied by the water intake pipe 30.

[0033] Of course, the movement of the water intake pipe 30 is not limited to rotation; it may also be linear movement or the like.

[0034] Furthermore, the cup lid 20 is provided with a movable window 23, which includes the bottom wall 232 and the top wall 231. The water intake pipe 30 is rotatably connected to the bottom wall 232 and / or the top wall 231, and the movable window 23 is used to limit the range of motion of the water intake pipe 30 and prevent excessive rotation. The exhaust port 21 is located on the bottom wall 232 and is provided facing the top wall 231. As a result, when water vapor inside the cup body 10 is discharged through the exhaust port 21, it does not come into direct contact with the human body, thus preventing burns to the user.

[0035] In this embodiment, when the water intake pipe 30 is in the first position, the water intake pipe 30 is housed inside the movable window 23. When the water intake pipe 30 moves from the first position to the second or third position, one end of the water intake pipe 30 rotates from inside the movable window 23 to outside the movable window 23. That is, since the water intake pipe 30 is housed inside the movable window 23 when not in use, damage or contamination of the water intake pipe 30 can be avoided, cleanliness can be maintained, and at the same time it is convenient for the user to carry. When in use, rotating the water intake pipe 30 from inside the movable window 23 to outside the movable window 23 enhances the convenience for the user when drawing water and makes operation easier.

[0036] Please refer to Figures 4 and 5. The intake pipe 30 includes a main body 31, a pipe section 32 connected to the main body 31, and a connecting section 33. The main body 31 is rotatably connected to the cup lid 20 via the connecting section 33, and the main body 31 is provided with a first through hole 34 and a first sealing section 36. The first through hole 34 is used to connect the pipe section 32 and the water inlet 22, and the first sealing section 36 is used to seal the water inlet 22.

[0037] In this embodiment, the cup lid 20 is provided with a mounting portion 27 on the upper wall 231 of the movable window 23, which is used for mounting and connecting to the connecting portion 33. The connecting portion 33 preferably has a convex structure, and the mounting portion 27 preferably has a concave structure. The convex structure and the concave structure fit together to connect the water intake pipe 30 and the cup lid 20, making processing and assembly easier.

[0038] In this embodiment, the cup lid 20 is provided with a surrounding portion 28 around the water inlet 22 and the exhaust port 21. This prevents bias that occurs when the water intake pipe 30 is rotated and improves the stability of rotation. At the same time, it is possible to enhance the sealing effect on the exhaust port 21 and the water inlet 22 when the water intake pipe 30 is in the first position. The exhaust port 21 and the water inlet 22 are provided with sealing pads 29, and the sealing pads 29 are provided with a first perforation 291 corresponding to the exhaust port 21 and a second perforation 292 corresponding to the water inlet 22, thereby preventing gaps caused by direct contact between the water intake pipe 30 and the cup lid 20 and further improving the sealing performance.

[0039] In the first embodiment, the main body 31 is further provided with a second through hole 35 and a second sealing portion 37. The second through hole 35 is used to connect to the exhaust port 21, and the second sealing portion 37 is used to seal the exhaust port 21.

[0040] When the water intake pipe 30 is in the first position, the first sealing part 36 seals the water inlet 22, and the second sealing part 37 seals the exhaust port 21, thereby preventing water leakage. When the water intake pipe 30 is in the second position, the first sealing portion 36 seals the water inlet 22, and the second through hole 35 connects to the exhaust port 21, facilitating the discharge of gas from inside the cup body 10 through the exhaust port 21. When the intake pipe 30 is in the third position, the second sealing portion 37 seals the exhaust port 21, and the first through hole 34 connects the pipe portion 32 and the water inlet 22, facilitating the outflow of liquid from the cup body 10 through the water inlet 22 and the pipe portion 32.

[0041] Preferably, the first through hole 34, the second through hole 35, the first sealing portion 36, and the second sealing portion 37 are arranged in an annular pattern at intervals along the central axis of the connecting portion 33. That is, the first through hole 34, the second through hole 35, the first sealing portion 36, the second sealing portion 37, and the connecting portion 33 of the present invention are provided adjacent to each other, resulting in a compact and small structure. The intake pipe 30 can be opened or closed by rotating it by only a small angle to open or close the exhaust port 21 and the water inlet 22.

[0042] Furthermore, the water intake pipe 30 further includes a pressing portion 38. By applying force to the pressing portion 38, the user can rotate the water intake pipe 30 without touching the pipe portion 32, thus avoiding contamination. The pressing portion 38 is provided with an anti-slip portion 39 (for example, an anti-slip protrusion), which increases the frictional force between the user's hand and the water intake pipe 30, making it easier to apply force, allowing for easy operation and preventing slippage.

[0043] For a second embodiment, please refer to Figures 13 and 14. The cup 100 further includes an elastic sealing structure 40, which is provided in the exhaust port 21. When the intake pipe 30 is in the first position, the pipe section 32 applies force to the elastic sealing structure 40, and the elastic sealing structure 40 seals the exhaust port 21. When the water intake pipe 30 moves from the first position to the second position, the pipe section 32 releases the force acting on the elastic sealing structure 40, causing the elastic sealing structure 40 to open the exhaust port 21.

[0044] Compared to the first embodiment, the differences in the second embodiment lie in the installation of the exhaust port 21 and the structure for sealing the exhaust port 21, and the second embodiment provides better sealing of the exhaust port 21.

[0045] Specifically, the elastic sealing structure 40 includes a sealing member 41 and an elastic member 42. The sealing member 41 is elastically attached to the exhaust port 21 via the elastic member 42. When the pipe portion 32 applies force to the sealing member 41, the sealing member 41 seals the exhaust port 21, and the elastic member 42 enters a state of stored energy. When the pipe portion 32 releases the force acting on the sealing member 41, the elastic member 42 returns to its original position, moving the sealing member 41 upward and opening the exhaust port 21. This enables automatic opening and improves user convenience.

[0046] In this embodiment, a conduit 11 is provided inside the cup body 10, the upper end of the conduit 11 is in communication with the water outlet 22, and the lower end of the conduit 11 extends to the bottom of the cup body 10. After the hot water in the cup body 10 has cooled down, the user can drink the water in the cup 100 directly through the water intake pipe 30 and the conduit 11, improving user convenience. Of course, the user can also pour the water from the cup body 10 through the water intake pipe 30 for use.

[0047] Please refer to Figures 7 to 12. The cup 100 further includes a fan structure 50, which is rotatably mounted on the cup lid 20. The fan structure 50 includes a bracket 51, a drive structure, and blades 53. The bracket 51 is rotatably connected to the cup lid 20, and the drive structure is connected to the blades 53 and drives the blades 53 to rotate. The bracket 51 is provided with an intake port 511 and an exhaust port 512 that communicate with the blades 53.

[0048] The drive structure includes a main control circuit board 521, a battery 522, and a motor 523. The battery 522 and the motor 523 are electrically connected to the main control circuit board 521, and the fan blades 53 are fixedly connected to the output shaft of the motor 523. The main control circuit board 521 is further provided with a control button 524, which is used to control the on / off state of the fan structure 50. The control button 524 is exposed on the surface of the cup lid 20, making it convenient for the user to control the on / off state of the fan structure 50.

[0049] When the fan structure 50 is not in use, it can be rotated until it is in close contact with the surface of the cup lid 20, and its structure is compact and convenient to carry. When it is necessary to use the fan structure 50, by rotating it to a preset angle, the fan structure 50 blows air towards the user, providing a cooling sensation (see Figure 12).

[0050] Furthermore, the bracket 51 includes a front cover 513 and a rear cover 514. The front cover 513 is provided with the exhaust port 512, and the rear cover 514 is provided with the intake port 511.

[0051] In this embodiment, the cup lid 20 includes a base 202 and a sealing lid 203, the base 202 and the sealing lid 203 are fitted together to form a housing cavity 24. The main control circuit board 521 and the battery 522 are mounted inside the housing cavity 24, and the sealing lid 203 is provided with a wiring groove 25 that communicates with the housing cavity 24. The wiring groove 25 is provided at the pivot connection end between the bracket 51 and the cup lid 20, facilitating the routing of the power cord 526 of the fan blades 53 through the housing cavity 24 for electrical connection with the main control circuit board 521. The wiring is streamlined and avoids interference between the power cord 526 and the rotation of the fan structure 50.

[0052] In this embodiment, the fan structure 50 further includes a cord retaining member 527, which is used to hold and secure the power cord 526 and prevent the power cord 526 from shifting.

[0053] The cup lid 20 is further provided with a waterproof silicone plate 525 and an insulating plate 54. The waterproof silicone plate 525 is provided on the sealing lid 203 to prevent water from entering the interior. The insulating plate 54 is provided at the bottom of the battery 522 and the main control circuit board 521 to prevent the liquid temperature inside the cup body 10 from being too high, which could affect the lifespan of the main control circuit board 521 and the battery 522.

[0054] The cup lid 20 is equipped with a silicone pad 26 at the rotating connection end of the bracket 51, which presses against the bottom of the rotating end of the fan structure 50, fixing the fan structure 50 at a specific angle and preventing wobbling.

[0055] In this embodiment, the fan structure 50 further includes a top cover 55. When the fan structure 50 is folded and in close contact with the cup lid 20, the top cover 55 covers the outside of the fan structure 50. The structure is compact and convenient for the user to carry.
