Description

Technical Field

[0001] This utility model relates to the field of water cup technology, specifically to a silicone deformation-driven sealed push-button diverter valve structure. Background Technology

[0002] The evaluation of a thermos cup mainly focuses on the length of time it keeps drinks hot. However, better heat retention means that the tea inside the thermos cup remains at a relatively high temperature, which is not a suitable drinking temperature. The problem with traditional thermos cups is not only that they do not keep drinks hot enough, but also that they cannot be drunk directly when needed, and there is a risk of burns.

[0003] Chinese patent CN106388492B discloses a push-button direct-drink dual-temperature cup, including a cup body and a lid mounted on the cup body. A water-insulating plate is provided inside the cup body, which divides the inner cavity of the cup body into a hot water zone and a warm water zone arranged sequentially from bottom to top. A water pipe is provided on the water-insulating plate, and a first passage and a second passage are opened in the water pipe. One end of the first passage and the second passage are both connected to the warm water zone, and the other end is both connected to the hot water zone. A control valve is connected to the water pipe, and the control valve controls the opening and closing of the first passage and the second passage simultaneously.

[0004] Specifically, the control valve includes a push-pull plate, a mounting seat, a push-pull rod, a spring, and a rotating handle. The mounting seat is fixed to a baffle plate on one side of the water pipe, and the push-pull plate is located on the other side of the water pipe. The push-pull plate is connected to the push-pull rod, and the other end of the push-pull rod is hinged to the rotating handle, which is hinged to the side wall of the cup. The spring pulls the push-pull plate towards the mounting seat, causing the push-pull plate to press against the mounting seat, flattening the water pipe between them and closing the first and second passages. Conversely, pulling the push-pull plate away from the mounting seat via the rotating handle connects the first and second passages.

[0005] The problem with the existing technology is that the rotating handle, as the driving component, is mounted on the outer wall of the cup body, while other components of the control valve and the water pipe are located inside the cup body, making assembly complex and sealing difficult to control. Therefore, the existing technology needs further improvement and development. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing a structurally sound, stable, and reliable silicone deformation-driven sealed push-button diverter valve structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: This utility model discloses a silicone deformation-driven sealed push-button diverter valve structure, comprising a cup body, wherein a heat-insulating base is provided inside the cup body, thereby dividing the inner cavity of the cup body into a first cavity and a second cavity arranged adjacent to each other; the heat-insulating base is provided with a water-permeable plate with a water-permeable structure, and a stop member movably disposed on the water-permeable plate to open or close the water-permeable structure; it also includes a trigger member, wherein a switch hole is provided on the side wall of the cup body, and a flexible disc seal is provided on the trigger member, the trigger member being movably inserted through the switch hole, and the flexible disc seal being fixed on the side wall of the cup body to seal the switch hole; the trigger member and the stop member are connected in a transmission manner, and when the trigger member is pressed or released, the flexible disc seal deforms, allowing the trigger member to move axially along the switch hole.

[0010] According to the above scheme, the permeable plate is provided with an actuating component and several guide holes, and the stop component and the actuating component are respectively located on both sides of the permeable plate; a connecting rod is passed through the guide hole, and the two ends of the connecting rod are respectively connected to the actuating component and the stop component; a spring is provided between the actuating component and the permeable plate, and the spring is fitted on one of the connecting rods. The spring drives the actuating component, so that the stop component always tends towards the permeable plate, thereby closing the permeable structure; the triggering component can drive the actuating component, so that the stop component moves away from the permeable plate, thereby opening the permeable structure.

[0011] According to the above scheme, the present invention also includes a valve body, which is protruding on the heat insulation base and placed in the second cavity.

[0013] According to the above scheme, a sealing ring is provided on the edge of the stop member. When the stop member approaches the permeable plate, the sealing ring fits against the permeable plate and surrounds the permeable structure to seal it.

[0014] According to the above scheme, the permeable structure includes a permeable opening, and the permeable plate is provided with at least two permeable openings, the diameter of which is greater than 2mm.

[0019] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0020] like Figure 1-3As shown, the silicone deformation-driven sealed push-button diverter valve structure of this utility model includes a cup body 1, with a heat-insulating base 2 inside the cup body 1, thereby dividing the inner cavity of the cup body 1 into a first cavity 11 and a second cavity 12 arranged adjacent to each other; the heat-insulating base 2 is provided with a water-permeable plate 3 with a water-permeable structure, and a stop member 31 movably disposed on the water-permeable plate 3 to open or close the water-permeable structure; it also includes a trigger member 13, with a switch hole 141 provided on the side wall of the cup body 1, and a flexible disc seal 16 provided on the trigger member 13. The trigger member 13 is movably inserted through the switch hole 141, and the flexible disc seal 16 is fixed on the side wall of the cup body 1 to seal the switch hole 141; the trigger member 13 is convexly connected to the stop member 31, and when the trigger member 13 is pressed or released, the flexible disc seal 16 deforms, allowing the trigger member 13 to move axially along the switch hole 141.

[0021] Preferably, the trigger 13 is disposed on the side wall of the cup body 1 and is connected to the stop member 31 in a driving manner. A switch hole 141 is provided on the side wall of the cup body 1, and the trigger 13 passes through the switch hole 141. A flexible disc seal 16 is provided on the trigger 13. The flexible disc seal 16 and the trigger 13 are integrally formed. The flexible disc seal 16 can seal the switch hole 141, and based on its own deformation capacity, the trigger 13 can move along the switch hole 141, driving the stop member 31 to change the state of the permeable structure. In particular, the flexible butterfly valve 131 can always maintain the sealed state of the switch hole 141 when it undergoes elastic deformation.

[0022] Pressing the trigger 13 activates the stop 31, opening the permeable structure. At this point, the first chamber 11 and the second chamber 12 are connected. Inverting the cup 1 allows hot water in the first chamber 11 to flow into the second chamber 12. Releasing the trigger 13 resets the stop 31, restoring the permeable structure to its normally closed state. This closes the connection between the first chamber 11 and the second chamber 12, allowing the cup 1 to be placed or carried in any position for greater convenience.

[0023] The cup body 1 is generally in an upright position. When placed on a table or carried by hand, the second cavity 12 is positioned above the first cavity 11. The shut-off element 31, in conjunction with the permeable plate 3, seals the permeable structure, preventing flow between the second cavity 12 and the first cavity 11. In short, the shut-off element 31 normally tends towards the permeable plate 3, keeping the permeable structure normally closed. In any state, the first cavity 11 and the second cavity 12 are not connected, and water and pressure cannot flow bidirectionally between the first cavity 11 and the second cavity 2.

[0024] Specifically, the side wall of the cup body 1 is provided with a sealing groove 14 and a molding compound 15, and the switch hole 141 is opened in the sealing groove 14; the flexible disc seal 16 is embedded in the sealing groove 14, and the molding compound 15 is paired with the sealing groove 14 to clamp the edge of the flexible disc seal 16.

[0025] The encapsulation groove 14 is provided with a switch hole 141 that penetrates the inner cavity of the cup body 1. The flexible disc seal 16 is embedded in the encapsulation groove 14 and can completely cover the switch hole 141. The plastic seal 15 cooperates with the encapsulation groove 14 to clamp the edge of the flexible disc seal 16, so that the switch hole 141 is sealed and leakage between the trigger 13 and the switch hole 141 is prevented.

[0026] Furthermore, the molding compound 15 is also embedded in the encapsulation groove 14, making it flush with the outer wall of the cup body 1. The molding machine 15 can be fixedly connected to the cup body 1 by adhesive bonding or ultrasonic welding, thereby fixing the flexible disc seal 16 in the encapsulation groove 14. This allows the flexible disc seal 16 to cover and seal the switch hole 141, and through its own deformation capability, the trigger 13 can move along the switch hole 141.

[0027] Specifically, the flexible disc seal 16 includes a flexible folding ring 161. The flexible disc seal 16, the flexible folding ring 161, and the trigger element 13 are an integrally molded structure made of silicone. The flexible disc seal 16 is connected to the middle of the trigger element 13 through the flexible folding ring 161. The molding compound 15 fixes the flexible disc seal 16 in the encapsulation groove 14, and the flexible disc seal 16 plays a sealing role. The molding compound 15 is provided with a through hole 151. The first end of the trigger element 13 passes through the switch hole 141 to be connected to the stop element 31, and the second end of the trigger element 13 protrudes from the outer wall of the cup body 1 through the through hole 151.

[0028] The second end of the trigger 13 passes through the through hole 151 and protrudes from the outer wall of the cup body 1, which allows the user to press the trigger 13. Through the deformation of the flexible folding ring 161, the trigger 13 can move relative to the flexible disc seal 16 along the switch hole 141 to drive the stop member 31.

[0029] The permeable plate 3 is provided with an actuating element 32 and several guide holes 33. The stop element 31 and the actuating element 32 are respectively located on both sides of the permeable plate 3. A connecting rod 34 passes through the guide hole 33, and the two ends of the connecting rod 34 are respectively connected to the actuating element 32 and the stop element 31. A spring 35 is provided between the actuating element 32 and the permeable plate 3. The spring 35 is fitted on one of the connecting rods 34. The spring 35 drives the actuating element 32, so that the stop element 31 always tends towards the permeable plate 3, thereby closing the permeable structure. The trigger element 13 can drive the actuating element 32, so that the stop element 31 moves away from the permeable plate 3, thereby opening the permeable structure.

[0030] The actuating element 32 and the shut-off element 31 are respectively disposed in the first cavity 11 and the second cavity 12 on both sides of the permeable plate 3. The shut-off element 31 and the actuating element 32 are connected by a connecting rod 34 and achieve synchronous action. The spring 35 can drive the actuating element 32 away from the permeable plate 3, and the corresponding shut-off element 31 will move towards the permeable plate 3 to close the permeable structure. Of course, the trigger element 13 can drive the actuating element 32 to overcome the force of the spring 35, so that the shut-off element 31 moves away from the permeable plate 3 and opens the permeable structure.

[0031] Specifically, the permeable plate 3 and the stop member 31 are face-to-face. The permeable plate 3 can be directly set on the heat insulation base 2 to form an integral structure with it. Since the second cavity 12 and the first cavity 11 are arranged adjacent to each other vertically, the stop member 31 can move up and down to cooperate with the permeable plate 3 to realize the on / off control of the permeable structure.

[0032] Preferably, the shut-off element 31 is disposed within the first cavity 11. Due to the heat insulation properties of the lower half of the cup 1, the water temperature and pressure in the first cavity 11 are very high. The upper half of the cup 1, however, does not have heat insulation properties. As time passes, the water in the second cavity 12 gradually cools down, and the pressure in the second cavity 12 is lower than that in the first cavity 11. The increased pressure in the first cavity 11 causes the shut-off element 31 to adhere more tightly to the permeable plate 3, thereby enhancing the sealing performance of the permeable structure.

[0033] This utility model also includes a valve body 21, which protrudes from the heat-insulating base 2 and is positioned within the second cavity 12. One side wall of the valve body 21 is formed by the permeable plate 3. The heat-insulating base 2 is provided with a drain outlet 22, which connects the inner cavity of the valve body 21 and the first cavity 11. A stop element 31 is movably disposed within the inner cavity of the valve body 21, and an actuating element 32 is movably disposed within the second cavity 12. The valve body 21, the permeable plate 3, the actuating element 32, the stop element 31, and the spring 35 constitute a normally closed stop valve. The valve body 21 is used to create space for installing the various functional components of the stop valve and to separate the permeable plate 3 from the heat-insulating base 2, thus avoiding an overly complex structure for the heat-insulating base 2.

[0034] In particular, the valve body 21 protrudes from the heat-insulating base 2, and the valve body 21 causes the permeable plate 3 to be vertically mounted on the heat-insulating base 2. The valve body 21 is eccentrically positioned on the heat-insulating base 2, thereby bringing the permeable plate 3 closer to the side wall of the cup body 1. The trigger 13 is located on the side wall of the cup body 1 where the second cavity 12 is located. The actuating element 32 and the shut-off element 31 move laterally relative to the permeable plate 3, so that the movement direction of the trigger 13 and the actuating element 32 is the same. By pressing the trigger 13 on the cup body 1, the actuating element 32 can be directly driven to achieve the on / off control of the shut-off valve. In particular, the protruding valve body 21 allows the permeable plate 3 to be closer to the side wall of the cup body 1, making it easier for the trigger 13 to drive the actuating element 32 and the shut-off element 31, and shortening the trigger stroke of the trigger 13.

[0035] It is understood that the actuator 32 and the stopper 31 are connected by a connecting rod 34. The connecting rod 34 can slide along the guide hole 33, so that the actuator 32 and the stopper 31 tend to or move away from the permeable plate 3. The actuator 32, the connecting rod 34 and the stopper 31 are linked together as a whole. These three components need to be made of rigid materials to avoid deformation during operation.

[0036] Therefore, a sealing ring 36 is provided on the edge of the stop member 31. When the stop member 31 approaches the permeable plate 3, the sealing ring 36 adheres to the permeable plate 3 and surrounds the permeable structure to seal it. The stop member 31 and the permeable plate 3 form a surface-to-surface fit. The fit between rigid materials has insufficient sealing performance. Therefore, a sealing ring 36 needs to be provided on the edge of the stop member 31. The stop member 31 approaches and adheres to the permeable plate 3, and the sealing ring 36 surrounds the permeable structure and the guide hole 33 to achieve the control of the flow on both sides of the permeable plate 3.

[0037] The permeable structure includes a water inlet 301. At least two water inlets 301 are provided on the permeable plate 3, and the diameter of each water inlet 301 is greater than 2 mm. The water inlets 301, the inner cavity of the valve body 21, and the drain outlet 22 constitute a water passage connecting the first cavity 11 and the second cavity 12. A stop element 31 is disposed in the inner cavity of the valve body 21 and cooperates with the permeable plate 3 to control the opening and closing of the water inlets 301. Similarly, when the cup body 1 is inverted, water in the first cavity 11 can flow into the second cavity 12. Due to the limited area of ​​the permeable plate 3 and the limited diameter of the water inlets 301, if there is only one water inlet 301 on the permeable plate 3, the surface tension of the water will form a pressure barrier within the hole, making it difficult for water to pass through. In this embodiment, the permeable plate 3 is provided with at least two permeable ports 301, and multiple passages are provided between the inner cavity of the valve body 21 and the second cavity 12. This can both expand the flow rate of the permeable structure and prevent water blockage by the pressure difference fluctuation between the multiple permeable ports 301.

[0038] In short, since both the first cavity 11 and the second cavity 12 are sealed, the water in the first cavity 11 needs to flow to the second cavity 12, and the air in the second cavity 12 needs to flow to the first cavity 11, forming a water-air exchange. The permeable plate 3 has multiple water inlets 301, which allows water and air to pass through the water inlets 301 on the permeable plate 3 simultaneously (in opposite directions), preventing the formation of a water seal (barrier) at the permeable plate 3.

[0039] Furthermore, the shape of the water inlet 301 does not need to be specially designed. Generally, the water inlet 301 can be round, square or rectangular, but the water inlet 301 of any shape cannot be too small. That is, the diameter of the round water inlet 301 needs to be greater than 2mm, and the width of the square water inlet 301 needs to be greater than 2mm.

[0040] Preferably, the diameter of the water inlet 301 is 3mm. The larger the diameter of the water inlet 301, the more difficult it is for water to form a water seal (barrier) at the water inlet 301.

[0041] Furthermore, the permeable structure also includes an air return groove 302. At least one air return groove 302 is provided on the permeable plate 3, located below the water inlet 301. The air return groove 302 is an elongated opening with a width greater than 1 mm. The permeable plate 3 is vertically arranged, the length direction of the air return groove 302 is parallel to the vertical direction, and the air return groove 302 is vertically corresponding to the water inlet 301.

[0042] When the cup body 1 moves from tilted to inverted, water in the first chamber 11 enters the inner cavity of the valve body 21, causing a change in the water level within the valve body 21. Since the return air groove 302 is located above the water inlet 301, water preferentially submerges the water inlet 301. Of course, fluctuations in the water level within the valve body 21 will also partially or completely submerge the return air groove 302. However, due to the height difference between the return air groove 302 and the water inlet 301, water in the first chamber 11 preferentially enters the second chamber 12 through the water inlet 301. The air pressure in the second chamber 12 can then enter the first chamber 11 through the return air groove 302, thus completing the water-air exchange. If the return air groove 302 is also completely submerged, the cup body 1 can be tilted appropriately to reduce the water seal pressure at the return air groove 302 (reducing the immersion depth), allowing the air pressure in the second chamber 12 to break through the water seal (barrier) at the return air groove 302.

[0043] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
