Description

Technical Field

[0001] This application relates to the field of water cup technology, and more particularly to a water cup. Background Technology

[0002] A straw cup is a water cup with a built-in straw. It usually consists of a lid, a cup body, and a straw. The lid fits onto the cup body, and the straw is attached to the lid. One end of the straw extends into the cup body, and the other end extends out of the cup body.

[0003] Most straw cups on the market close the straw by deforming it. However, this method of closing the straw is not very stable. In some cases, water in the cup will still flow out of the cup through the straw. At the same time, the deformation of the straw can easily cause it to break, resulting in water leakage and affecting the lifespan of the cup. Summary of the Invention

[0004] This application provides a water cup that improves the sealing performance when the cup is closed, while also increasing the cup's service life.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include:

[0006] This application provides a water cup, including a cup lid body, a sealing element, and a cup body. The cup body has a cavity with an opening. The cup lid body is mounted on the opening. The cup lid body has an intake channel, a switching channel, and a pressure relief channel. The intake channel and pressure relief channel extend along the thickness direction of the cup lid body and are both connected to the cavity. The switching channel is connected to both the intake channel and the pressure relief channel. The sealing element is mounted on the switching channel. The switching channel includes a closed section located between the intake channel and the pressure relief channel. Furthermore, the seal has a degree of freedom of movement along the extension direction of the switch channel, so that the water cup lid body has an open state for absorbing water and a closed state for sealing the cavity; when the water cup lid body is in the open state, the seal is separated from the water absorption channel and the pressure relief channel respectively, and the seal is at least partially located in the closed section to isolate the water absorption channel and the pressure relief channel; when the water cup lid body is in the closed state, the seal extends into the water absorption channel to close the water absorption channel, and at the same time, the seal abuts against the opening of the pressure relief channel facing the switch channel to close the pressure relief channel.

[0007] Furthermore, the sealing element includes a first sealing part and a second sealing part, with a pressure relief space between the first sealing part and the second sealing part; when the water cup lid body is in the closed state, the first sealing part extends into the water absorption channel to close the water absorption channel, while the second sealing part abuts against the opening of the pressure relief channel facing the switch channel to close the pressure relief channel; when the water cup lid body is in the open state, the first sealing part is at least partially located in the closed section, and the opening of the switch channel communicates with the pressure relief space.

[0008] Furthermore, the sealing element includes a sealing head and a guide rod, with the sealing head mounted on the end of the guide rod facing the water suction channel; a first sealing part is located on the sealing head, and a second sealing part is located on the guide rod.

[0009] Furthermore, the main body of the cup lid also includes a pressure relief component, which is installed in the pressure relief channel and extends toward the switch channel; when the main body of the cup lid is in the closed state, the sealing component abuts against the pressure relief component.

[0010] Furthermore, the connection point between the water intake channel and the switch channel forms a connection port; along the extension direction of the switch channel, the connection port is located between the two ends of the switch channel.

[0011] Furthermore, the water cup also includes a lever, which is installed on the water cup lid body. One end of the lever extends outside the water cup lid body, and the other end extends into the switch channel. The lever has a degree of freedom to swing relative to the water cup lid body, and the seal moves under the action of the lever.

[0012] Furthermore, the main body of the water cup lid includes an end cap, a water-absorbing component, and a baffle. The water-absorbing component is installed on the end cap and extends at least partially into the cavity. The baffle is installed on the water-absorbing component and has a degree of freedom of movement relative to the water-absorbing component. The lever extends through the baffle and out of the main body of the water cup lid.

[0013] Furthermore, the water cup also includes a straw assembly, which is installed in the part of the water-absorbing component that extends into the cavity.

[0014] Furthermore, a first sealing ring is installed between the straw assembly and the absorbent component; a second sealing ring is installed between the end cap and the absorbent component; the straw assembly is connected to the absorbent component via threads, and the straw assembly at least partially abuts against the end cap.

[0015] Furthermore, the water cup also includes a connecting pad and a handle. The connecting pad is fitted over the main body of the water cup, the handle is fitted over the main body of the water cup, and the inner wall of the handle abuts against the connecting pad.

[0016] The sealing element simultaneously opens and closes both the water intake channel and the pressure relief channel of the water cup, ensuring the water cup's airtightness when closed and preventing leakage. At the same time, the sealing element extends directly into the water intake channel to close it, eliminating the need for bending or deforming the water cup components, thereby extending the water cup's lifespan.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, in one implementation, this application provides a water cup, including a water cup lid body 1, a sealing member 2, and a water cup body 4. The water cup body 4 is used to store liquid. The water cup lid body 1 covers the water cup body 4 to seal the water cup body 4, thereby facilitating the storage of liquid in the water cup body 4. At the same time, the water cup lid body 1 can also serve as part of a straw, making it convenient for users to draw the liquid stored in the water cup body 4. The sealing member 2 is installed inside the water cup lid body 1 and is used to control the opening and closing of the water cup lid body 1.

[0029] Specifically, a cavity 401 is formed inside the water cup body 4, which is used to store liquid. The cavity 401 has an opening 4011, and the water cup lid body 1 is installed in the opening 4011.

[0030] The main body 1 of the water cup lid has a water suction channel 101, a switch channel 102, and a pressure relief channel 107. The water suction channel 101 is used to draw liquid from the main body 4 of the water cup. The switch channel 102 is used to install the seal 2 and to open and close the water suction channel 101 and the pressure relief channel 107 through the seal 2. The pressure relief channel 107 is used to stabilize the air pressure in the cavity 401. That is, when the user draws liquid from the cavity 401 through the water suction channel 101, the air outside the water cup flows into the cavity 401 through the pressure relief channel 107, thereby facilitating the user to continuously draw liquid from the cavity 401.

[0031] The water intake channel 101 and the pressure relief channel 107 extend along the thickness direction of the water cup lid body 1, and both the water intake channel 101 and the pressure relief channel 107 are connected to the cavity 401. The switch channel 102 is connected to the water intake channel 101 and the pressure relief channel 107, respectively.

[0032] Furthermore, the water suction channel 101 is provided through the main body 1 of the water cup lid so that the user can draw liquid from the water cup through the water suction channel 101. The two ends of the pressure relief channel 107 are respectively connected to the cavity 401 and the switch channel 102.

[0033] The seal 2 is installed on the switch channel 102, and the seal 2 has a degree of freedom of movement that can move along the extension direction of the switch channel 102, that is, the seal 2 can move along the switch channel 102.

[0034] It should be noted that the seal 2 and the switch channel 102 are in a sliding seal, that is, the switch channel 102 is always in a closed state when the seal 2 moves to any position of the switch channel 102. At the same time, the switch channel 102 is also in a closed state when the seal 2 slides relative to the switch channel 102.

[0035] The switch channel 102 includes a closed section 1024, which is located between the water intake channel 101 and the pressure relief channel 107. During the movement of the seal 2, at least a portion of the seal 2 is always located within the closed section 1024, thereby ensuring that the switch channel 102 is always in a closed state and preventing liquid from flowing out of the switch channel 102.

[0036] The seal 2 moves relative to the switch channel 102, so that the cup lid body 1 has an open state and a closed state. When the cup lid body 1 is open, the water suction channel 101 and the pressure relief channel 107 are open, and the user can draw liquid from the cup through the cup lid body 1. When the cup lid body 1 is closed, the water suction channel 101 and the pressure relief channel 107 are closed, and the cavity 401 is in a sealed state, thereby ensuring the water cup's airtightness and preventing liquid from flowing out of the cavity 401.

[0037] When the water cup lid body 1 is in the open state, the sealing element 2 is separated from the water suction channel 101 and the pressure relief channel 107 respectively, and the water suction channel 101 and the pressure relief channel 107 are open. The user can draw liquid from the water cup through the water cup lid body 1. At the same time, the sealing element 2 is at least partially located in the closed section 1024, which isolates the water suction channel 101 and the pressure relief channel 107 to ensure water suction stability.

[0038] When the water cup lid body 1 is in the closed state, the sealing element 2 extends into the water suction channel 101, sealing the water suction channel 101. At the same time, the sealing element 2 abuts against the opening of the pressure relief channel 107 facing the switch channel 102, thereby sealing the pressure relief channel 107. On the one hand, closing the water suction channel 101 by the sealing element 2 prevents liquid from flowing out of the water cup, improving the water cup's sealing performance. On the other hand, even when the water suction channel 101 still has a certain opening, closing the pressure relief channel 107 allows atmospheric pressure to prevent liquid from flowing out of the water suction channel 101, further improving the water cup's sealing performance.

[0039] The sealing element 2 simultaneously opens and closes the water intake channel 101 and the pressure relief channel 107 of the water cup, ensuring the water cup's airtightness when closed and preventing leakage. At the same time, the sealing element 2 extends directly into the water intake channel to close it, eliminating the need to bend or deform the water cup components, thereby improving the water cup's service life.

[0040] To more clearly illustrate the technical solution of this application, the following definitions are provided: Figure 1 The directions shown are up, down, left, and right. The thickness direction of the main body 1 of the water cup lid is [not specified]. Figure 1 The vertical direction is shown. The direction of movement of seal 2 is... Figure 1 The left and right directions are shown.

[0041] like Figure 2 and Figure 5 As shown, in one implementation, the water cup lid body 1 includes an end cap 103 and a water suction member 104. The water suction member 104 is installed on the end cap 103, and the end cap 103 covers the water cup. The water suction member 104 provides a suction nozzle for the user to suck up the liquid in the water cup.

[0042] By dividing the water cup lid body 1 into an end cap 103 and a water-absorbing component 104, the sealing component 2 can be easily installed into the water cup lid body 1, thus improving the ease of installation.

[0043] like Figure 6As shown, specifically, the end cap 103 includes an end cap groove 1031 and a connecting groove 1032. The end cap groove 1031 is located on the side of the end cap 103 away from the water cup. The water-absorbing member 104 is installed in the end cap 103 through the end cap groove 1031. The connecting groove 1032 is located on the side of the end cap groove 1031 facing the water cup body 4, and the connecting groove 1032 communicates with the end cap groove 1031 so that at least a portion of the water-absorbing member 104 can extend into the water cup, thereby facilitating the absorption of liquid in the water cup.

[0044] The pressure relief channel 107 is located inside the end cap groove 1031, so that the end cap groove 1031 is connected to the cavity 401 through the pressure relief channel 107.

[0045] The water suction channel 101 and the switch channel 102 are located inside the water suction component 104, which improves the production convenience of the water cup lid body 1.

[0046] like Figure 7 As shown, specifically, the water-absorbing component 104 includes a cover plate 1041, a water-absorbing body 1042, and a switch body 1043. The water-absorbing channel 101 is located inside the water-absorbing body 1042 and extends through the water-absorbing body 1042. The switch channel 102 is located inside the switch body 1043, and the switch channel 102 has only one opening for installing the seal 2 into the switch channel 102. The cover plate 1041 is connected to the water-absorbing body 1042 and is used to close the top of the end cap groove 1031.

[0047] The switch body 1043 is positioned perpendicular to the water absorption body 1042, so that the water absorption channel 101 and the switch channel 102 are perpendicular to each other.

[0048] Optionally, both the water absorption channel 101 and the switch channel 102 are cylindrical channel structures, and the axis of the water absorption channel 101 and the axis of the switch channel 102 are located in the same plane and perpendicular to each other.

[0049] It should be noted that the water absorption channel 101 and the switching channel 102 can be square or other polygonal channel structures. Furthermore, the axis of the water absorption channel 101 can spatially intersect with the axis of the switching channel 102, as long as the water absorption channel 101 and the switching channel 102 are connected.

[0050] As one implementation method, the connection position of the water absorption channel 101 and the switch channel 102 forms a connection port 105.

[0051] Along the extending direction of the switch channel 102, the switch channel 102 includes a first end and a second end, and the communication port 105 is located between the first end and the second end of the switch channel 102.

[0052] When the water suction channel 101 is closed, the seal 2 abuts against the end of the switch channel 102, so that the water suction channel 101 is located in the middle of the seal 2, thereby improving the sealing performance and stability of the seal 2 in closing the water suction channel 101.

[0053] As one implementation, along the extension direction of the water suction channel 101, when the water suction channel 101 is in the closed state, the projection of the water suction channel 101 is located within the projection range of the seal 2.

[0054] Specifically, on the cross-section passing through the axis of the seal 2, the edge of the seal 2 is located outside the edge of the water absorption channel 101. That is, the diameter of the part of the seal 2 used to close the water absorption channel 101 is larger than the diameter of the water absorption channel 101, thereby ensuring that the seal 2 can stably close the water absorption channel 101 and improving the sealing performance of the cup lid when the water absorption channel 101 is in the closed state.

[0055] As one implementation, a sealing protrusion 1021 is formed in the switch channel 102. When the water absorption channel 101 is in the closed state, the sealing member 2 abuts against the sealing protrusion 1021 to seal the water absorption channel 101. The sealing performance between the sealing member 2 and the water absorption channel 101 is further improved by the sealing protrusion 1021, thereby improving the sealing performance of the cup lid when the water absorption channel 101 is in the closed state.

[0056] As one implementation method, the plane formed by the tips of the sealing protrusions 1021 is perpendicular to the extension direction of the water absorption channel 101, which further improves the sealing performance of the sealing element 2 in closing the water absorption channel 101.

[0057] In this implementation, the sealing protrusion 1021 is U-shaped and extends along the water absorption channel 101. The sealing protrusion 1021 is located in the middle of the switch channel 102, that is, the tip of the sealing protrusion 1021 is located in the horizontal plane passing through the axis of the seal 2.

[0058] like Figure 2 , Figure 3 and Figure 8 In one implementation, the seal 2 includes a first sealing part 203 and a second sealing part 204, the first sealing part 203 and the second sealing part 204 are arranged along the moving direction of the seal 2, and there is a pressure relief space 205 between the first sealing part 203 and the second sealing part 204.

[0059] When the water cup lid body 1 is in the closed state, the first sealing part 203 extends into the water absorption channel 101 and closes the connecting port 105, thereby closing the water absorption channel 101. At the same time, the second sealing part 204 abuts against the opening of the pressure relief channel 107 facing the switch channel 102 to close the pressure relief channel 107.

[0060] When the water cup lid body 1 is in the open state, the first sealing part 203 is at least partially located in the closed section 1024, and the opening of the switch channel 102 is connected to the pressure relief space 205.

[0061] In one implementation, the seal 2 includes a sealing head 201 and a guide rod 202. The sealing head 201 is mounted on the end of the guide rod 202 facing the water absorption channel 101. A first sealing part 203 is located on the sealing head 201, and a second sealing part 204 is located on the guide rod 202.

[0062] Specifically, the first sealing part 203 is the circumferential sidewall of the sealing head 201, and the second sealing part 204 is a protruding structure extending downward from the guide rod 202.

[0063] Furthermore, the sealing head 201 is made of flexible materials such as rubber. Under normal conditions, the diameter of the sealing head 201 is larger than the inner diameter of the switch channel 102, thereby sealing the switch channel 102 through the sealing head 201.

[0064] The guide rod 202 is a rigid rod that provides guidance for the movement of the sealing head 201.

[0065] There is a certain gap between the second sealing part 204 and the sealing head 201, so that there is a pressure relief space 205 between the first sealing part 203 and the second sealing part 204.

[0066] As one implementation, a through groove 1025 is formed at the bottom of the switch channel 102, and the second sealing part 204 is located in the through groove 1025 and can slide in the through groove 1025 so that the second sealing part 204 can abut or separate from the pressure relief channel 107.

[0067] As one implementation, the water cup lid body 1 also includes a pressure relief component 108, which is installed in the pressure relief channel 107 and extends toward the switch channel 102; when the water cup lid body 1 is in the closed state, the sealing component 2 abuts against the pressure relief component 108.

[0068] Specifically, the pressure relief component 108 is made of flexible materials such as rubber so that when the sealing component 2 comes into contact with the pressure relief component 108, the pressure relief component 108 will deform, thereby further improving the sealing performance of the pressure relief channel 107 in the closed state.

[0069] At the same time, the pressure relief component 108 extends at least partially into the through groove 1025 so that the second sealing part 204 abuts against the pressure relief component 108.

[0070] Furthermore, the top of the pressure relief component 108 is conical, which facilitates the movement of the second sealing part 204 above the pressure relief component 108. At the same time, the pressure relief component 108 with a conical top can deform stably, thereby improving the sealing performance of the pressure relief channel 107 in the closed state.

[0071] In one implementation, the guide rod 202 is formed with a guide portion 2021, which is located on the side wall of the guide rod 202 and extends along the moving direction of the seal 2.

[0072] A guide groove 1023 is formed in the switch channel 102, and the guide groove 1023 extends along the moving direction of the seal 2.

[0073] Furthermore, the guide part 2021 is inserted into the guide groove 1023. The guide part 2021 and the guide groove 1023 cooperate to guide the movement of the seal 2, improve the movement stability of the seal 2, and prevent relative rotation of the seal 2 during movement, thereby further preventing leakage at the switch channel 102 during the movement of the seal 2.

[0074] It should be noted that there is a certain distance between the end of the guide groove 102 facing the water suction channel 101 and the water suction channel 101, so as to prevent the guide groove 102 from communicating with the water suction channel 101 and ensure that the switch channel 102 is always in the closed state during the movement of the seal 2.

[0075] like Figure 2 and Figure 5 As shown, in one implementation, the cup lid also includes a lever 3, which is installed on the cup lid body 1 and extends at least partially into the switch channel 102. The lever 3 drives the seal 2 to move relative to the switch channel 102.

[0076] Specifically, a cover plate groove 10411 is formed on the cover plate 1041, and a switch groove 1022 is formed on the top of the switch channel 102. The lever 3 passes through the cover plate groove 10411 and the switch groove 1022 in sequence and then extends into the switch channel 102.

[0077] As one implementation method, the middle part of the lever 3 is rotatably mounted on the water cup lid body 1 via the pivot 301, so that the lever 3 can swing relative to the water suction part 104.

[0078] One end of the lever 3 is connected to the seal 2, and the other end of the lever 3 extends to the outside of the cup lid body 1 through the cover plate groove 10411, so that the user can swing the lever 3 to move the seal 2 along the switch channel 102.

[0079] Specifically, the water-absorbing component 104 also includes a connecting plate 1044, which is connected to the outer wall of the switch body 1043 and the lower end face of the cover plate 1041 respectively, and the rotating shaft 301 is connected to the connecting plate 1044.

[0080] Furthermore, a slot 2022 is formed on the seal 2, and the end of the lever 3 facing the seal 2 is inserted into the slot 2022. A connecting post 2023 is connected in the slot 2022.

[0081] Correspondingly, a connecting groove 302 is formed on the end of the lever 3 facing the seal 2, and the connecting post 2023 is connected to the connecting groove 302, thereby connecting the lever 3 to the seal 2. The seal 2 is moved by swinging the lever 3, so that it moves within the switch channel 102.

[0082] It should be noted that the connecting post 2023 can move relative to the connecting groove 302 to prevent the lever 3 from interfering with the seal 2 during the swinging process.

[0083] As another implementation method, the lever 3 is slidably installed on the water suction component 104, and the sealing component 2 is moved by the translation of the lever 3.

[0084] It should be noted that in this implementation, the lever 3 and the seal 2 can be an integral structure or separate structures, and the lever 3 and the seal 2 are fixedly connected, so that the lever 3 can drive the seal 2 to move left or right along the switch channel.

[0085] As one implementation, the water-absorbing component 104 also includes a baffle 106, which is mounted on the connecting plate 1044 and can move along the extension direction of the switch channel 102.

[0086] A baffle groove 1061 is formed on the baffle 106, and the baffle groove 1061 at least partially overlaps with the cover groove 10411, so that the lever 3 can extend to the outside of the cup lid body 1 through the baffle groove 1061 and the cover groove 10411 in sequence.

[0087] During the swinging or moving of the lever 3, the baffle 106 can move along with the swinging or moving of the lever 3, and the baffle 106 can block the cover groove 10411 to prevent foreign objects from entering the switch channel 102.

[0088] It should be noted that during the swinging or moving of the lever 3, only the baffle groove 1061 and the cover groove 10411 of the baffle 106 are connected, and the rest of the cover groove 10411 is blocked by the baffle 106.

[0089] In one implementation, the absorbent 104 extends at least partially into the cavity 401, and the cup also includes a straw assembly 5, which is installed in the portion of the absorbent 104 that extends into the cavity 401.

[0090] Specifically, the water-absorbing body 1042 is installed in the connecting groove 1032, and the water-absorbing body 1042 extends at least partially outside the connecting groove 1032, so that the water-absorbing body 1042 extends into the cavity 401, and the straw assembly 5 is installed in the part of the water-absorbing body 1042 that extends into the cavity 401.

[0091] like Figure 2 and Figure 3 As shown, in one implementation, the straw assembly 5 is threadedly installed on the part of the water-absorbing body 1042 that extends into the cavity 401.

[0092] When installing the straw assembly 5, rotate the straw assembly 5 so that it abuts against the bottom surface of the end cap 103. At the same time, a limiting ring 10421 is formed on the outer circumferential wall of the water-absorbing body 1042. During the installation of the straw assembly 5, the limiting ring 10421 moves toward the straw assembly 5 until it abuts against the inner wall of the connecting groove 1032, thereby locking the straw assembly 5 and the water-absorbing body 1042.

[0093] In one implementation, a first sealing ring 6 is installed between the straw assembly 5 and the water-absorbing component 104; a second sealing ring 7 is installed between the end cap 103 and the water-absorbing component 104; the straw assembly 5 is connected to the water-absorbing component 104 by threads, and the straw assembly 5 at least partially abuts against the end cap 103.

[0094] Specifically, the first sealing ring 6 is installed between the outer wall of the water-absorbing body 1042 and the inner wall of the straw assembly 5.

[0095] The second sealing ring 7 is installed between the lower end face of the limiting ring 10421 and the upper end face of the connecting groove 1032.

[0096] The connection between the end cap 103, the water-absorbing component 104, and the straw assembly 5 is sealed by the first sealing ring 6 and the second sealing ring 7, preventing the connection between the end cap 103, the water-absorbing component 104, and the straw assembly 5 from becoming a dead water zone, thereby improving the drinking safety of the water cup.

[0097] In one implementation, the straw assembly 5 includes a straw connector 501 and a tube 502. The upper end of the straw connector 501 has a threaded hole 5011 for installing the straw connector 501 to the water-absorbing body 1042. The lower end of the straw connector 501 has an insertion hole 5012 for inserting the tube 502 into the insertion hole 5012.

[0098] A handle plate 5013 is formed on the outer circumference of the straw connector 501. The handle plate 5013 facilitates the rotation of the straw connector 501, thereby improving the assembly convenience of the straw assembly 5 and the water-absorbing body 1042.

[0099] like Figure 2 and Figure 4 As shown, in one implementation, the water cup also includes a connecting pad 8 and a handle 9. The connecting pad 8 is sleeved on the outside of the water cup body 4, and the handle 9 is sleeved on the outside of the water cup body 4, with the inner wall of the handle 9 abutting against the connecting pad 8.

[0100] Specifically, the connecting pad 8 is made of flexible materials such as rubber, so that the connection strength between the handle 9 and the cup body 4 can be increased by the deformation of the connecting pad 8.

[0101] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.

[0102] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
