Description

Technical Field

[0001] The present application relates to the technical field of water containers, and in particular to a water cup. Background Art

[0002] Thermos cups are a common type of water cup in our daily lives. They are popular among consumers because they are easy to carry and can preserve hot water for a long time.

[0003] In order to ensure the sealing performance of the thermos cup in the prior art, the cup lid of the thermos cup is generally detachably connected to the cup body by a threaded structure. When closing or opening the lid, a large screwing force is required to achieve a stable seal, which makes the use process more troublesome.

[0004] Of course, there are also more novel thermos cups in the prior art, in which the cup lid and the cup body are connected by a "hinge + snap-on" method. When the lid is closed, the cup lid is rotated around the hinge axis and fixed to the cup body by being snap-on. When opening, the unlocking button is pressed, and the cup lid can be rotated in the opposite direction around the hinge axis to open the cup body. However, this type of cup lid cannot be removed from the cup body, and is not easy to clean after long-term use. Some detachable types also have to use a threaded structure, and a large screwing force is required when disassembly is required.

[0005] Therefore, there is an urgent need for a water cup with a simple structure and a conveniently detachable cup cover on the market. Summary of the invention

[0006] In view of this, the present application provides a water cup with a new structure to solve the problem that the cup cover of the water cup in the prior art is difficult to disassemble and has a complex structure.

[0007] The water cup provided in the present application comprises a cup body and a cup cover covering the cup body;

[0008] The cup cover comprises an outer cover and an inner cover, wherein the outer cover covers the outer peripheral wall of the opening of the cup body, and the inner cover is arranged inside the cup body;

[0009] The outer cover is also provided with a locking assembly, and the locking assembly is connected to the inner cover via a transmission assembly;

[0010] When the locking assembly is pressed to lock, the transmission assembly can drive the inner cover to move toward the outer cover, and make the inner cover abut against the inner peripheral wall of the opening of the cup body to lock;

[0011] When the locking assembly is pressed to unlock, the transmission assembly can drive the inner cover to move away from the outer cover, and the inner cover is no longer locked against the inner peripheral wall of the opening of the cup body.

[0012] When it is necessary to fix the cup lid on the cup body, you only need to insert the inner cover in the cup lid into the opening of the cup body first, and fit the outer cover in the cup lid on the outer peripheral wall of the opening of the cup body, and finally press the locking assembly to lock it. At this time, the transmission assembly can drive the inner cover to move toward the outer cover, and make the inner cover abut against the inner peripheral wall of the opening of the cup body to lock, so that the cup lid is fixed on the cup body; when it is necessary to remove the cup lid from the cup body, you only need to press the locking assembly to unlock it. At this time, the transmission assembly can drive the inner cover to move away from the outer cover, and make the inner cover no longer abut against the inner peripheral wall of the opening of the cup body to lock, so that the cup lid can be removed from the opening of the cup body.

[0013] Compared with the thermos cup in the prior art, the water cup completely adopts a new covering method, which not only allows the cup cover to be completely removed from the cup body, but also has the advantages of labor-saving disassembly and simple structure.

[0014] In a possible design, the locking assembly includes a locking member, an unlocking member and a latch assembly:

[0015] The locking member is arranged in the vertical direction, one end of which is away from the outer cover and is a locking pressing end, and the other end is in contact with the transmission assembly, and the locking member is provided with a through hole in the horizontal direction;

[0016] The unlocking member is correspondingly arranged at one end or both ends of the through hole along the horizontal direction, and one end of the unlocking member facing away from the outer cover is an unlocking pressing end, and the other end is an abutting end;

[0017] The bayonet assembly is disposed in the through hole, and the bayonet assembly can extend out of the through hole or retract in the through hole;

[0018] Wherein, when the locking assembly is in a locking state, the latch assembly at least partially extends out of the through hole and applies a force to the unlocking member to move away from the outer cover;

[0019] When the locking assembly is in the unlocking condition, the latch assembly is completely retracted into the through hole and no longer abuts against the unlocking member.

[0020] In this way, the locking part can keep the locking assembly locked after one press; the locking part can be unlocked by pressing the unlocking part to squeeze the pin assembly back into the through hole. In this way, the unlocking part can keep the locking assembly unlocked after one press. It has the advantages of simple structure and the ability to clearly distinguish the locking or unlocking function through the locking part and the unlocking part.

[0021] In a possible design, the bayonet assembly includes a pin head and an elastic member;

[0022] The pin head is disposed in the through hole, and the pin head can at least partially extend from an end of the through hole;

[0023] The elastic member is arranged in the through hole and connected to the pin head;

[0024] Wherein, the elastic member is used to apply elastic force to the pin head to extend out of the through hole.

[0025] In this way, the elastic member can always apply elastic force to the pin head to extend out of the through hole. As long as the through hole of the locking member is flush with the corresponding second mounting hole in the top cover, the pin head can partially extend into the second mounting hole to limit the locking of the locking member. It has the advantages of simple structure, stable locking of the locking member, and convenient unlocking of the locking member.

[0026] In one possible design, the transmission assembly includes a plug, a lever and an elastic member;

[0027] The plug is arranged on a side of the inner cover facing the outer cover, and one end of the plug extends into the outer cover:

[0028] The lever is arranged in the outer cover, and one end of the lever is hinged to the plug through a hinge shaft, and the other end of the lever is in contact with the locking member;

[0029] The elastic member is disposed between the inner cover and the outer cover, and is used to apply a force to the inner cover away from the outer cover;

[0030] When the locking member is pressed to move downward, the lever can rotate around the hinge shaft and drive the inner cover to move upward, and the elastic member can be compressed to store elastic potential energy.

[0031] In this way, when the locking piece squeezes the free end of the lever downward, the lever can rotate around the hinge axis and drive the inner cover to move upward, so that the inner cover and the inner circumferential wall of the opening of the cup body are abutted and locked; when the locking piece no longer squeezes the free end of the lever downward, the elastic piece can release the elastic potential energy stored when it is under pressure, so that the lever rotates in the opposite direction around the hinge axis and drives the inner cover to move downward, so that the inner cover and the inner circumferential wall of the opening of the cup body are no longer abutted and locked. It has the advantages of simple structure and can stably drive the inner cover to move upward or downward.

[0032] In a possible design, the outer cover includes a bottom cover and a top cover;

[0033] The bottom cover is detachably covered on the outer peripheral wall of the opening of the cup body;

[0034] The top cover is covered on a side of the bottom cover away from the cup body, and together with the bottom cover, forms a cavity for installing the transmission assembly;

[0035] Wherein, the locking member is partially located in the cavity and can squeeze the transmission assembly in the cavity along the vertical direction to drive the inner cover to move up and down.

[0036] In this way, when making the outer cover, the bottom cover and the top cover can be injection molded separately through two molds, which is more convenient to manufacture; on the other hand, when assembling the cup cover, the transmission component can be installed on the bottom cover first, the locking part can be installed on the top cover, and then the top cover and the bottom cover can be closed, which is more convenient to assemble.

[0037] In a possible design, the top cover is provided with a first mounting hole for mounting the locking member in a vertical direction, and one end of the first mounting hole is in communication with the cavity;

[0038] The top cover is provided with a second mounting hole for mounting the unlocking member in a horizontal direction, and one end of the second mounting hole is connected to the first mounting hole;

[0039] Wherein, when the second mounting hole is flush with the through hole, the latch assembly can extend out of the through hole to lock and fix the locking member.

[0040] In this way, the user can use the thumb to press the locking part in the vertical direction and use the index finger to press the unlocking part in the horizontal direction, so that the user can press the locking component more conveniently and with less effort.

[0041] In a possible design, a limiting plug is further provided at one end of the second mounting hole away from the first mounting hole;

[0042] The limiting plug and the second mounting hole together form a limiting space for mounting the unlocking member.

[0043] By providing the above-mentioned limiting plug, it is possible to prevent the unlocking member from excessively extending out of the second mounting hole, thereby preventing the unlocking member from falling off from the second mounting hole.

[0044] In a possible design, the inner cover includes a cover plate and a retaining edge arranged around the periphery of the cover plate;

[0045] When the inner cover moves toward the outer cover, the inner peripheral wall of the retaining edge can abut against the outer cover and cause the retaining edge to elastically expand away from the cover plate;

[0046] When the locking assembly is locked, the outer peripheral wall of the retaining edge can be abutted and locked with the inner peripheral wall of the opening of the cup body, so that the cup cover is fixedly covered on the cup body.

[0047] In this way, when the inner cover moves toward the outer cover, the retaining edge can elastically expand under the abutting force of the outer cover, so that the inner cover can better abut and lock with the inner circumferential wall of the opening of the cup body. It has the advantages of simple structure and can firmly abut and lock with the inner circumferential wall of the opening of the cup body through the expansion effect of the retaining edge.

[0048] In a possible design, notch grooves are spaced apart in the retaining edge along the circumference of the retaining edge.

[0049] In this way, when the retaining edge elastically expands under the abutting force of the outer cover, the notch groove can make the retaining edge elastically expand more easily and to a greater extent.

[0050] In a possible design, the outer peripheral wall of the retaining edge is also sleeved with a sealing sleeve;

[0051] The blocking edge can be indirectly abutted and locked with the inner peripheral wall of the opening of the cup body through the sealing sleeve.

[0052] On the one hand, this can increase the airtightness of the baffle edge and the inner wall of the opening of the cup body when they abut against each other, further improving the heat preservation and leakage prevention effect after the cup lid is closed on the cup body; on the other hand, when the baffle edge moves downward to retract and recover, the sealing sleeve can also release its own elastic potential energy, so that the baffle edge can retract and recover faster and better.

[0053] In a possible design, the opening of the cup body is a constricted opening, and the inner peripheral wall of the cup body has an inclined section inclined toward the center of the cup body;

[0054] The inclined section can be abutted and locked by the inner cover.

[0055] In this way, when the inner cover abuts and locks with the inner peripheral wall of the opening of the cup body, the retaining edge can indirectly abut against the inclined section through the sealing sleeve, thereby further improving the abutment and locking firmness of the two.

[0056] Other features and advantages of the embodiments of the present application will be described in the subsequent description, and partly become apparent from the description, or understood by practicing the embodiments of the present application.

In addition, in the context, it is also necessary to understand that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0094] The following describes a specific embodiment of the water cup according to the structure of the embodiment of the present application.

[0095] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a water cup, which includes a cup body 1 and a cup cover 2 covering the cup body 1; the cup cover 2 includes an outer cover 21 and an inner cover 22, and the outer cover 21 covers the open outer peripheral wall of the cup body 1, and the inner cover 22 is arranged inside the cup body 1; the outer cover 21 is also provided with a locking assembly 3, and the locking assembly 3 is connected to the inner cover 22 through a transmission assembly 4; when the locking assembly 3 is pressed to lock, the transmission assembly 4 can drive the inner cover 22 to move toward the outer cover 21, and make the inner cover 22 abut against the inner peripheral wall of the opening of the cup body 1 for locking; when the locking assembly 3 is pressed to unlock, the transmission assembly 4 can drive the inner cover 22 to move away from the outer cover 21, and make the inner cover 22 no longer abut against the inner peripheral wall of the opening of the cup body 1 for locking.

[0096] When the water cup is in use, when it is necessary to cover the cup cover 2 on the cup body 1, it is only necessary to first insert the inner cover 22 in the cup cover 2 into the opening of the cup body 1, and cover the outer cover 21 in the cup cover 2 on the outer peripheral wall of the opening of the cup body 1, and finally press the locking component 3 to lock it. At this time, the transmission component 4 can drive the inner cover 22 to move toward the outer cover 21, and make the inner cover 22 abut and lock with the inner peripheral wall of the opening of the cup body 1, so that the cup cover 2 is fixed to the cup body 1; when it is necessary to remove the cup cover 2 from the cup body 1, it is only necessary to press the locking component 3 to unlock it. At this time, the transmission component 4 can drive the inner cover 22 to move away from the outer cover 21, and make the inner cover 22 no longer abut and lock with the inner peripheral wall of the opening of the cup body 1, so that the cup cover 2 can be removed from the opening of the cup body 1.

[0097] Compared with the thermos cup in the prior art, the water cup completely adopts a new covering method, which not only allows the cup cover 2 to be completely removed from the cup body 1, but also has the advantages of labor-saving disassembly and simple structure.

[0098] In the optional scheme of this example, the locking assembly 3 includes a locking member 31, an unlocking member 32 and a pin assembly 33; the locking member 31 is arranged in the vertical direction, and the end away from the outer cover 21 is a locking pressing end, and the other end abuts against the transmission assembly 4, and the locking member 31 is provided with a through hole 311 in the horizontal direction; the unlocking member 32 is arranged correspondingly at one end or both ends of the through hole 311 in the horizontal direction, and the end of the unlocking member 32 away from the outer cover 21 is an unlocking pressing end, and the other end is an abutting end; the pin assembly 33 is arranged in the through hole 311, and the pin assembly 33 can extend out of the through hole 311 or retract in the through hole 311.

[0099] Among them, when the locking assembly 3 is in the locking condition, the pin assembly 33 at least partially extends out of the through hole 311 and applies a force to the unlocking member 32 to move away from the outer cover 21; when the locking assembly 3 is in the unlocking condition, the pin assembly 33 is completely retracted in the through hole 311 and no longer abuts against the unlocking member 32.

[0100] Specifically, Figure 1 , Figure 2 and Figure 5 As shown, the locking assembly 3 is specifically configured to include a locking member 31, an unlocking member 32, and a latch assembly 33, and when the locking member 31 is pressed, the locking member 31 can drive the inner cover 22 to move toward the outer cover 21 through the transmission assembly 4, so that the inner cover 22 abuts against the inner peripheral wall of the opening of the cup body 1 and is locked. In addition, the locking member 31 can be fixed in position by extending the latch assembly 33 out of the through hole 311, so that the locking member 31 can keep the locking assembly 3 locked after one press; the locking member 31 can be unlocked by pressing the unlocking member 32 to squeeze the latch assembly 33 back into the through hole 311, so that the unlocking member 32 can keep the locking assembly 3 unlocked after one press.

[0101] The specific configuration of the above-mentioned locking assembly 3 has the advantages of simple structure and the ability to clearly distinguish the locking or unlocking function through the locking member 31 and the unlocking member 32 .

[0102] Of course, the above-mentioned locking assembly 3 can also be set to other structures, such as a self-locking switch similar to the prior art, and the locking or unlocking function of the locking assembly 3 is achieved by pressing the locking button for the first time and pressing the unlock button again.

[0103] In an optional solution of this example, the pin assembly 33 includes a pin head 331 and an elastic member 332; the pin head 331 is arranged in the through hole 311, and the pin head 331 can at least partially extend from the end of the through hole 311; the elastic member 332 is arranged in the through hole 311 and connected to the pin head 331; wherein the elastic member 332 is used to apply an elastic force to the pin head 331 to extend out of the through hole 311.

[0104] Specifically, Figure 1 and Figure 5 As shown, the above-mentioned pin head 331 can be specifically provided with two or one. Figure 1 and Figure 5 Two pin heads 331 are correspondingly arranged in the through hole 311, and the two ends of the elastic member 332 are respectively connected to the two pin heads 331. The elastic member 332 is specifically but not limited to being arranged as a compression spring, so that the elastic member 332 can always apply an elastic force to the two pin heads 331 to extend out of the through hole 311, thereby ensuring that as long as the through hole 311 of the locking member 31 is flush with the corresponding second mounting hole 212b in the top cover 212, the pin head 331 can partially extend into the second mounting hole 212b to limit the locking of the locking member 31.

[0105] The specific configuration of the above-mentioned latch assembly 33 has the advantages of simple structure, being able to stably lock the latching member 31 and being able to conveniently unlock the latching member 31 .

[0106] In the optional scheme of this example, the transmission assembly 4 includes a plug 41, a lever 42 and an elastic member 43; the plug 41 is arranged on the side of the inner cover 22 facing the outer cover 21, and one end extends into the outer cover 21; the lever 42 is arranged in the outer cover 21, and one end is hinged to the plug 41 through a hinge shaft, and the other end is abutted against the locking member 31; the elastic member 43 is arranged between the inner cover 22 and the outer cover 21, and is used to apply a force to the inner cover 22 away from the outer cover 21; wherein, when the locking member 31 is pressed to move downward, the lever 42 can rotate around the hinge shaft and drive the inner cover 22 to move upward, and the elastic member 43 can be compressed to store elastic potential energy.

[0107] Specifically, Figure 1 and Figure 3As shown, the transmission assembly 4 is specifically configured to be a plug 41, a lever 42 and an elastic member 43, so that when the locking member 31 presses the free end of the lever 42 downward, the lever 42 can rotate around the hinge axis and drive the inner cover 22 to move upward, so that the inner cover 22 is abutted and locked with the inner peripheral wall of the opening of the cup body 1; when the locking member 31 no longer presses the free end of the lever 42 downward, the elastic member 43 can release the elastic potential energy stored when it is under pressure, so that the lever 42 can rotate in the opposite direction around the hinge axis and drive the inner cover 22 to move downward, so that the inner cover 22 is no longer abutted and locked with the inner peripheral wall of the opening of the cup body 1.

[0108] The specific configuration of the transmission assembly 4 has the advantages of being simple in structure and being able to stably drive the inner cover 22 to move upward or downward.

[0109] It is worth noting that the above-mentioned plugs 41 and levers 42 can be arranged in multiple groups in a one-to-one correspondence, and the free end of the lever 42 can face different directions.

[0110] In the optional scheme of this example, the outer cover 21 includes a bottom cover 211 and a top cover 212; the bottom cover 211 is detachably covered on the outer peripheral wall of the opening of the cup body 1; the top cover 212 is covered on the side of the bottom cover 211 away from the cup body 1, and together with the bottom cover 211, it forms a cavity for installing the transmission assembly 4; wherein, the locking member 31 is partially located in the cavity, and can squeeze the transmission assembly 4 in the cavity along the vertical direction to drive the inner cover 22 to move up and down.

[0111] Specifically, Figure 1 and Figure 3 As shown, the outer cover 21 is specifically configured as a bottom cover 211 and a top cover 212 covering the bottom cover 211, and the top cover 212 and the bottom cover 211 together form a cavity for installing the transmission assembly 4, and the locking member 31 is partially located in the cavity and can move vertically in the cavity to extrude the transmission assembly 4. In this way, on the one hand, when making the outer cover 21, the bottom cover 211 and the top cover 212 can be injection molded separately through two molds, which is more convenient to make; on the other hand, when assembling the cup cover 2, the transmission assembly 4 can be installed on the bottom cover 211, the locking member 31 can be installed on the top cover 212, and then the top cover 212 can be covered with the bottom cover 211 to facilitate assembly.

[0112] The specific configuration of the outer cover 21 has the advantages of being easy to manufacture and assemble.

[0113] In the optional scheme of this example, the top cover 212 is provided with a first mounting hole 212a for installing the locking member 31 along the vertical direction, and one end of the first mounting hole 212a is connected to the cavity; the top cover 212 is provided with a second mounting hole 212b for installing the unlocking member 32 along the horizontal direction, and one end of the second mounting hole 212b is connected to the first mounting hole 212a; wherein, when the second mounting hole 212b is flush with the through hole 311, the pin assembly 33 can extend out of the through hole 311 to lock and fix the locking member 31.

[0114] Specifically, Figure 5 As shown, the first mounting hole 212a is opened in the top cover 212 along the vertical direction, and the second mounting hole 212b is opened in the top cover 212 along the horizontal direction, so that the user can use the thumb to press the locking member 31 in the vertical direction and use the index finger to press the unlocking member 32 in the horizontal direction, so that the user can press the locking assembly 3 more conveniently and with less effort.

[0115] In an optional solution of this example, a limiting plug 212c is further provided at one end of the second mounting hole 212b away from the first mounting hole 212a; the limiting plug 212c and the second mounting hole 212b together form a limiting space for installing the unlocking member 32.

[0116] Specifically, Figure 5 As shown, the above-mentioned limit plug 212c is preferably arranged in a ring shape, so that when the limit plug 212c is installed on one end of the second mounting hole 212b, the unlocking member 32 can partially pass through the limit plug 212c for the user to press. Of course, the above-mentioned limit plug 212c can also be arranged in an elastic sheet shape to completely block one end of the second mounting hole 212b, and the function of pressing the unlocking member 32 can also be achieved by relying on the elastic deformation of the limit plug 212c itself.

[0117] By providing the above-mentioned limiting plug 212c, it is possible to prevent the unlocking member 32 from excessively extending out of the second mounting hole 212b, thereby preventing the unlocking member 32 from falling off from the second mounting hole 212b.

[0118] In the optional scheme of this example, the inner cover 22 includes a cover plate 221 and a retaining edge 222 arranged around the periphery of the cover plate 221; when the inner cover 22 moves toward the outer cover 21, the inner peripheral wall of the retaining edge 222 can abut against the outer cover 21 and elastically expand the retaining edge 222 away from the cover plate 221; when the locking assembly 3 is locked, the outer peripheral wall of the retaining edge 222 can abut against the inner peripheral wall of the opening of the cup body 1 to lock the cup cover 2 so that the cup cover 2 is fixedly covered on the cup body 1.

[0119] Specifically, Figure 4As shown, the inner cover 22 is specifically configured as a cover plate 221 and a retaining edge 222 arranged around the periphery of the cover plate 221, and the cover plate 221 and the retaining edge 222 can be processed and formed by an integral injection molding method, so that when the inner cover 22 moves toward the outer cover 21, the retaining edge 222 can elastically expand under the abutting force of the outer cover 21, so that the inner cover 22 can better abut and lock with the inner peripheral wall of the opening of the cup body 1.

[0120] The specific arrangement of the inner cover 22 has the advantages of being simple in structure and being able to be firmly abutted and locked with the inner peripheral wall of the opening of the cup body 1 through the expansion effect of the retaining edge 222 .

[0121] In an optional solution of this example, along the circumference of the retaining edge 222 , notch grooves 222 a are spaced apart in the retaining edge 222 .

[0122] Specifically, Figure 4 As shown, notch grooves 222a are provided at intervals along the circumference of the retaining edge 222, so that when the retaining edge 222 elastically expands under the abutting force of the outer cover 21, the notch grooves 222a can make the retaining edge 222 elastically expand more easily and to a greater extent.

[0123] The above-mentioned notch grooves 222a can be arranged in multiple numbers at even intervals along the circumference of the retaining edge 222, and the notch grooves 222a can be formed into U-shaped grooves.

[0124] In an optional solution of this example, the outer peripheral wall of the retaining edge 222 is further provided with a sealing sleeve 222b; the retaining edge 222 can be indirectly abutted and locked with the inner peripheral wall of the opening of the cup body 1 through the sealing sleeve 222b.

[0125] Specifically, Figure 3 As shown, the sealing sleeve 222 b can be made of food-grade silicone material, and the sealing sleeve 222 b can be configured to wrap the cover plate 221 and the retaining edge 222 at the same time.

[0126] By setting the sealing sleeve 222b, on the one hand, the airtightness of the retaining edge 222 and the inner peripheral wall of the opening of the cup body 1 can be increased when the retaining edge 222 abuts against the inner peripheral wall of the opening of the cup body 1, and the heat preservation and leakage prevention effect after the cup cover 2 covers the cup body 1 can be further improved; on the other hand, when the retaining edge 222 moves downward to retract and restore, the sealing sleeve 222b can also release its own elastic potential energy, so that the retaining edge 222 can retract and restore faster and better.

[0127] In an optional solution of this example, the opening of the cup body 1 is a constricted opening, and the inner peripheral wall of the cup body 1 has an inclined section 11 inclined toward the center of the cup body 1; the inclined section 11 can allow the inner cover 22 to abut and lock.

[0128] Specifically, Figure 1As shown, the opening of the cup body 1 is set to be a constricted opening, and the inner circumferential wall of the cup body 1 has an inclined section 11 inclined toward the center of the cup body 1, so that when the inner cover 22 abuts and locks with the inner circumferential wall of the opening of the cup body 1, the retaining edge 222 can indirectly abut against the inclined section 11 through the sealing sleeve 222b, thereby further improving the abutment and locking firmness of the two.

[0129] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
