Description

Technical Field

[0001] This application relates to the field of water cup technology, and in particular to a valve body and a cooling and insulated cup. Background Technology

[0002] With the development of the water bottle industry, water bottles that can both keep warm and cool are now available on the market, namely, cooling and insulated water bottles. The principle is to set up an insulated chamber and a cooling chamber, with a controllable valve between them. The walls of the cooling chamber are filled with a cooling substance. When drinking water is needed, the valve is controlled to open the insulated chamber and the cooling chamber, allowing the hot water in the insulated chamber to flow to the cooling chamber, which can quickly cool it to a drinkable temperature. Finally, the lid can be opened to drink.

[0003] In actual use, the insulation chamber of a current cooling and insulated cup is usually filled with tea. Therefore, current cooling and insulated cups are equipped with a tea filter near the outlet of the insulation chamber. In this way, the tea in the insulation chamber first passes through the tea filter to prevent the tea leaves from flowing to the valve body, and then the filtered tea flows through the valve body to the cooling chamber.

[0004] Because tea leaves easily adhere to the tea filter, and smaller tea leaves can remain in the valve body through the filter, the tea filter and valve body need to be cleaned frequently. Traditionally, cleaning the tea filter requires removing the lid and valve body first, and then taking out the tea filter itself. Furthermore, the tea filter is located deep inside the cup, making it difficult to disassemble and reassemble, resulting in low cleaning efficiency for current insulated mugs. Utility Model Content

[0005] Therefore, it is necessary to provide a valve body and a cooling and insulation cup for a thermos cup to improve the cleaning efficiency of the thermos cup.

[0006] In a first aspect, embodiments of this application provide a valve body for a cooling and insulated cup, the cooling and insulated cup further including a control component disposed on its outer side and drivenly connected to the valve body, the valve body comprising:

[0007] A bracket is installed inside the cooling and insulated cup and is sealed to the boundary between the insulation chamber and the cooling chamber of the cooling and insulated cup. The bracket is provided with a water passage hole connecting the insulation chamber and the cooling chamber.

[0008] A valve stem is provided on the bracket and is reciprocally movable along the depth direction of the cooling and heat preservation cup. The control component is drivenly connected to the valve stem.

[0009] A sealing element, connected to the valve stem and placed inside the insulation chamber, is controlled by a control unit that drives the valve stem to reciprocate along the depth of the cup, thereby closing or opening the water passage; and

[0010] A filter element with filter holes is provided. One end of the filter element is connected to the bracket and is arranged around the water passage hole. The other end is sleeved on the sealing element, and the edge of the sealing element is fitted and sealed with part of the inner ring surface of the filter element. The part of the filter element that is not sealed and fitted with the sealing element is connected to the liquid storage space inside the cooling and thermos cup through the filter holes.

[0011] In one embodiment, the seal or the filter is made of rubber, silicone, or a resiliently deformable plastic material.

[0012] In one embodiment, the seal is an annular member, the radial dimension D1 of the end of the seal away from the bracket is greater than the radial dimension D2 of the end of the seal near the bracket, and the circumferential edge of the end of the seal away from the bracket is in contact with and sealed to a portion of the inner annular surface of the filter element.

[0013] In one embodiment, the seal includes a coaxially connected columnar portion and an annular boss portion. The columnar portion is close to the bracket and is used to close or open the water passage. The radial dimension of the columnar portion is D2, and the bottom radial dimension of the annular boss portion is D1. The bottom circumferential edge of the annular boss portion is fitted and sealed with a portion of the inner ring surface of the filter element.

[0014] In one embodiment, the bracket has an annular boss that closes at both ends and surrounds the water passage hole, the filter element is annular in structure, the filter hole is opened on the annular sidewall of the filter element, and the filter element is sleeved on the annular boss and sealed.

[0015] In one embodiment, the valve body further includes a sealing ring disposed between the filter element and the annular boss;

[0016] And / or, the filter element is made of rubber, silicone or elastically deformable plastic material, and the valve body also includes a clamping member, which is sleeved on the corresponding engagement area of ​​the filter element and the annular boss to tighten the filter element and the annular boss for sealing.

[0017] In one embodiment, the seal and the valve stem are detachably sealed together.

[0018] In one embodiment, the seal has a mounting hole, the portion of the valve stem connected to the seal has a snap fastener, the portion of the valve stem with the snap fastener passes through the mounting hole of the seal, the snap fastener engages with the end edge of the mounting hole, and the valve stem is sealed to the mounting hole.

[0019] In one embodiment, the valve body further includes a first elastic element, one end of which is connected to the valve stem, and the other end of which is connected to the bracket;

[0020] The first elastic element is in an elastic compression or elastic tension state, so as to elastically drive the valve stem to move the sealing element closer to the bracket, so that the sealing element closes the water passage hole.

[0021] In one embodiment, the valve body further includes a mounting bracket connected to the bracket, the mounting bracket being sleeved over the cooling and insulated cup and sealingly engaging with the mouth of the cooling and insulated cup;

[0022] The cooling and insulated cup also includes a cup lid, which is threadedly connected to the valve body mounting bracket at the mouth of the cooling and insulated cup to close or open the cooling and insulated cup.

[0023] In one embodiment, the control element is reciprocally movable along the depth direction of the cup and passes through the cup lid, and is sealed with the cup lid;

[0024] The control component located inside the cooling and insulation cup abuts against the valve stem along the cup depth direction. When the control component moves towards the inside of the cooling and insulation cup along the cup depth direction, it can drive the valve stem to move the sealing component synchronously to open the water passage.

[0025] In one embodiment, the control component includes a pressing part, a pushing part, and a connecting part. The connecting part connects the pressing part and the pushing part and is reciprocally movable through the cup lid along the cup depth direction. The pressing part is located on the outside of the cup lid, and the pushing part is located on the inside of the cup lid and abuts against the valve stem along the cup depth direction.

[0026] The control component also includes a second elastic element. One end of the second elastic element is connected to the cup lid, and the other end of the second elastic element is connected to the pressing part. The second elastic element is in an elastic compression or elastic tension state to elastically drive the pressing part to have a tendency to move away from the cup lid, so that the pressing part can rebound and reset after being pressed towards the inside of the cup lid.

[0028] In the valve body of the aforementioned cooling and insulated cup, the support provides stable support and, through a sealing fit at the boundary between the insulation and cooling chambers, ensures the independence of the two chambers, preventing liquid leakage between them. The valve stem is driven by the control component, converting external pressure into internal valve action. The valve stem reciprocates along the cup depth, achieving linear control and simplifying operation. The seal moves with the valve stem, closing or opening the water passage. The seal, located inside the insulation chamber in a higher temperature environment, helps improve sealing based on the principle of thermal expansion and contraction. The filter surrounds the water passage, intercepting tea residue through its filter holes. One end of the filter is connected to the support, and the other end is fitted with the seal, forming a filtration barrier. The filter hole design allows liquid to pass through but blocks solids; combined with the tight fit of the seal, it prevents tea residue from entering the valve body, simplifying cleaning.

[0029] Therefore, the valve body of the cooling and insulated cup of this application uses a bracket as the base, a valve stem for transmission, a sealing element to control the flow, and a filter element for protection. This integration reduces complexity, and the filter element can be cleaned simply by disassembling the valve body, thus solving the problem of tea filters being difficult to remove due to their deep placement in related technologies.

[0045] See Figure 1 , Figure 2 , Figure 4 and Figure 7 An embodiment of this application provides a valve body for a cooling and insulated cup. The valve body 1 includes a bracket 11, a valve stem 12, a seal 13, and a filter 14. The bracket 11 serves as a mounting carrier for mounting the valve stem 12, the seal 13, and the filter 14. Figure 4 and Figure 7As shown, the bracket 11 is installed inside the thermos cup and is sealed to the boundary between the insulation chamber 3 and the cooling chamber 4. The bracket 11 has a water passage hole 111 connecting the insulation chamber 3 and the cooling chamber 4. The valve stem 12 is reciprocally movable along the depth of the thermos cup and is mounted on the bracket 11. The control element 2 is driven by the valve stem 12. The sealing element 13 is connected to the valve stem 12 and placed inside the insulation chamber 3. The control element 2 drives the valve stem 12 to move the sealing element 13 reciprocally along the depth of the cup to close or open the water passage hole 111. When drinking water is needed, the control element 2 drives the valve stem 12 to move towards the bottom of the cup. At this time, the sealing element 13 is released from the water passage hole 111, and the insulation chamber 3 and the drinking chamber are connected. Hot water enters the drinking chamber from the insulation chamber 3 through the water passage hole 111. When no water is needed, the control unit 2 drives the valve stem 12 to move away from the bottom of the cup. At this time, the seal 13 seals with the water passage 111, and the heat preservation chamber 3 and the water drinking chamber are disconnected.

[0046] The filter element 14 has filter holes 141. One end of the filter element 14 is connected to the bracket 11 and surrounds the water passage hole 111. The other end is sleeved on the sealing element 13, with the edge of the sealing element 13 fitting and sealing against a portion of the inner ring surface of the filter element 14. The portion of the filter element 14 not sealed against the sealing element 13 communicates with the internal liquid storage space of the cooling and insulated cup through the filter holes 141. The filter element 14 is integrated on the valve body 1 via the bracket 11. When the tea filter needs to be cleaned, the valve body 1 can be removed to take out the filter element 14 for cleaning, improving the disassembly and assembly efficiency of the tea filter, and thus improving the cleaning efficiency of the cooling and insulated cup. Furthermore, the portion of the filter element 14 not fitted against the sealing element 13 communicates with the internal liquid storage space of the cooling and insulated cup through the filter holes 141. The sealing element 13 and the filter element 14 work together to perform a filtering function, simplifying the structure of the tea filter and reducing the production cost of the cooling and insulated cup.

[0047] It should be noted that in this application, the cooling and insulated cup also includes a control component 2 located on its outer side and drivenly connected to the valve body 1. That is, the control component 2 can drive the valve body 1 to open or close the insulation chamber 3 and the cooling chamber 4. It should also be noted that in this application, the cup depth direction refers to the height direction of the cooling and insulated cup.

[0048] In the valve body 1 of the aforementioned cooling and insulated cup, the bracket 11 provides stable support and, through a sealing fit with the boundary between the insulation chamber 3 and the cooling chamber 4, ensures the independence of the insulation chamber 3 and the cooling chamber 4, preventing liquid leakage between them. The valve stem 12 is driven by the control component 2, converting external pressing into internal valve body action. The valve stem 12 moves back and forth along the depth of the cup, achieving linear control and simplifying operation. The sealing element 13 moves with the valve stem 12, closing or opening the water passage 111. The sealing element 13 is placed inside the insulation chamber 3, in a higher temperature environment, which, according to the principle of thermal expansion and contraction, helps to improve the sealing performance. The filter element 14 surrounds the water passage 111, intercepting tea residue through the filter hole 141. One end of the filter element 14 is connected to the bracket 11, and the other end is fitted with the sealing element 13, forming a filter barrier. The filter hole 141 is designed to allow liquid to pass through but block solids. Combined with the fit of the sealing element 13, it prevents tea residue from entering the valve body, simplifying cleaning.

[0049] Therefore, the valve body 1 of the cooling and thermos cup of this application uses the bracket 11 as the base, the valve stem 12 for transmission, the sealing element 13 for flow control, and the filter element 14 for protection. The integration reduces complexity, and the filter element 14 can be cleaned simply by disassembling the valve body 1, thus solving the problem of tea filters being difficult to remove due to deep placement in related technologies.

[0050] The bracket 11 can be made of stainless steel or plastic, and is connected and fixed to the cooling and insulated cup by means of threads or snaps, sealing the boundary between the insulated chamber 3 and the cooling chamber 4 inside the cup. The water passage 111 can be a round hole or a strip hole, with a diameter or width designed to be 2-5mm to balance flow rate and sealing. The valve stem 12 can be a cylindrical metal rod or a plastic rod, with a wear-resistant coating on the surface to ensure smooth operation over long-term use. The seal 13 can be a ring-shaped rubber part, connected to the valve stem by snaps for easy replacement. The filter element 14 can be a mesh structure with a filter pore diameter of 0.5-1mm, made of food-grade silicone or plastic, and can be completely disassembled and washed.

[0051] In some embodiments, the seal 13 is made of rubber or silicone or a plastic material that can undergo elastic deformation. The rubber / silicone is elastic and can fill microscopic gaps to improve the sealing effect. The elastic deformation allows the filter element 14 to fit tightly with the seal 13 to prevent leakage. At the same time, the elastic material provides good sealing performance and durability and adapts to temperature deformation. Moreover, the elastic material is combined with the structure of the valve stem 12 to enhance the sealing reliability and extend the service life.

[0052] Furthermore, such as Figure 2 , Figure 4 and Figure 5As shown, in one embodiment, the seal 13 is an annular member. The radial dimension D1 of the end of the seal 13 away from the support 11 is greater than the radial dimension D2 of the end of the seal 13 near the support 11. The circumferential edge of the end of the seal 13 away from the support 11 is fitted and sealed against a portion of the inner annular surface of the filter element 14. This simplifies the structure of the seal 13 and enables the edge of the seal 13 to fit and seal against a portion of the inner annular surface of the filter element 14.

[0053] The annular component provides a uniform circumferential sealing force, ensuring that the seal 13 fully covers the water passage 111 area during movement, thus improving sealing consistency. The setting that the radial dimension D1 of the end of the seal 13 furthest from the support 11 is larger than the radial dimension D2 of the end of the seal 13 closest to the support 11 creates a slope on the seal 13 geometry. When the valve stem 12 moves the seal 13, the larger circumferential edge (D1 end) can tightly adhere to the filter element 14 to achieve a seal, preventing tea residue from entering the filter element 14. Simultaneously, the smaller area (D2 end) has a gap with the filter element 14, allowing liquid to pass through and enter the water passage 111.

[0054] Furthermore, such as Figure 4 and Figure 5 As shown, in one embodiment, the seal 13 includes a coaxially connected columnar portion 131 and an annular boss portion 132. The columnar portion 131 is close to the bracket 11 and is used to close or open the water passage 111. The radial dimension of the columnar portion 131 is D2, and the bottom radial dimension of the annular boss portion 132 is D1. The bottom circumferential edge of the annular boss portion 132 is fitted and sealed with a portion of the inner ring surface of the filter element 14. The difference between the dimensions D1 and D2 prevents misalignment during installation of the seal 13 and the valve stem 12, improving the installation efficiency of the seal 13.

[0055] like Figure 4 As shown, the annular boss portion 132 has a deformation groove inside, which facilitates the outer wall of the annular boss portion 132 to be pressed and sealed against the inner ring surface of the filter element 14. This allows the portion of the filter element 14 not in contact with the seal 13 to communicate with the internal liquid storage space of the cooling and insulated cup through the filter hole 141. The seal 13 and the filter element 14 cooperate to perform a filtering function, simplifying the structure of the tea filter and reducing the production cost of the cooling and insulated cup.

[0056] It should be noted that the columnar part 131 is specifically used to open and close the water passage 111, and the annular boss part 132 expands the sealing area, realizes functional separation, reduces mutual interference, and improves overall stability. This overcomes the problem that the single-shaped seal 13 is prone to overall deformation under high pressure, resulting in uneven sealing, especially when the valve stem 12 moves frequently, the sealing surface may wear too quickly.

[0057] Furthermore, such as Figure 4 As shown, the bracket 11 has an annular boss 112 that is closed at both ends and surrounds the water passage hole 111. The filter element 14 is an annular structure with filter holes 141 opened on the annular sidewall of the filter element 14. The filter element 14 is sleeved on the annular boss 112 and is sealed.

[0058] The annular boss 112 serves as a medium connecting the bracket 11 and the filter element 14. The annular boss 112 and the filter element 14 are sleeved together to achieve integrated positioning, filtration, and sealing, reducing the number of parts and improving maintenance convenience. The sleeved design reduces alignment difficulty, making it particularly suitable for large-scale production, and overcomes the problems of cumbersome disassembly and assembly and low cleaning efficiency of traditional filtration systems and valve bodies.

[0059] In one embodiment, the valve body 1 further includes a sealing ring (not shown) disposed between the filter element 14 and the annular boss 112. The sealing ring, disposed between the filter element 14 and the annular boss 112, fills the gap, provides elastic cushioning, and ensures a static seal to overcome the problem of potential leakage of fine tea residue from the microscopic gaps between the filter element and the boss.

[0060] In some embodiments, the filter element 14 may be designed as a quick-release type, which is fixed by a rotating buckle. During cleaning, the filter element can be removed from the valve body 1 by rotating it, making it easy to clean the filter element 14.

[0061] Specifically, in one embodiment, the valve body 1 further includes a clamping member (not shown in the figure), which is sleeved on the corresponding engagement area between the filter element 14 and the annular boss 112 to tighten and seal the filter element 14 and the annular boss 112. The clamping member is a clamp structure and can be customized according to the dimensions of the filter element 14 and the annular boss, and can be purchased directly.

[0062] A clamping element is fitted onto the mating area to tighten and seal the filter element. The clamping element provides external clamping force to prevent filter element displacement and is suitable for high-pressure environments. Simultaneously, a sealing ring is positioned between the filter element 14 and the annular boss 112, working in conjunction with the clamping element to tighten and seal the filter element. The sealing ring and clamping element form a flexible and rigid sealing system. The sealing ring handles low-pressure leakage, while the clamping element withstands high-pressure deformation. This multiple design redundancy enhances safety.

[0063] It should be noted that, in one embodiment, a sealing ring may be fitted over the annular boss 112, and the sealing ring abuts against the inner wall of the cup body for sealing. This ensures that the bracket 11 is sealed to the boundary between the insulation chamber 3 and the cooling chamber 4 of the cooling and insulated cup.

[0064] Furthermore, such as Figure 4As shown, in some embodiments, the seal 13 and the valve stem 12 are detachably sealed together. When it is necessary to disassemble the seal 13, it can be directly removed from the valve stem 12. The detachable connection facilitates modular maintenance and extends product life.

[0065] Specifically, in one embodiment, the seal 13 has a mounting hole 133, and the portion of the valve stem 12 connected to the seal 13 has a snap fastener 121. The portion of the valve stem 12 with the snap fastener 121 passes through the mounting hole 133 of the seal 13, and the snap fastener 121 engages with the end edge of the mounting hole 133, thus providing a sealing fit between the valve stem 12 and the mounting hole 133. That is, when the seal 13 needs to be disassembled for cleaning, the snap fastener 121 is pressed to disengage it from the mounting hole 133, allowing the seal 13 to be removed. Figure 4 As shown, a sealing ring is fitted onto the outer wall of one end of the valve stem 12 located within the mounting hole 133, and the side wall of the sealing ring abuts against the inner wall of the mounting hole 133 to create a seal. This ensures a seal between the sealing element 13 and the valve stem 12.

[0066] Mounting hole 133 provides a standardized interface, allowing precise insertion of valve stem 12, ensuring alignment and reducing assembly errors. Simultaneously, the hole structure facilitates mass production and quality inspection of seal 13. The snap-fit ​​provides mechanical interlocking, forming a flexible snap-fit ​​structure to ensure a stable connection; the protrusion design of snap-fit ​​121 deforms upon insertion and resets after insertion, achieving a self-locking function. The snap-fit ​​ensures mechanical fixation, and the sealing fit blocks leakage paths, achieving both connection and sealing functions. The diameter of mounting hole 133 can be set according to the size of valve stem 12. For example, when the valve stem 12 diameter is 3mm, the mounting hole diameter is 3.1-3.2mm, forming a transition fit. During manufacturing, mandrel injection molding is used to ensure the coaxiality of the hole is ≤0.05mm. The snap-fit ​​can be a single-point or multi-point design; for example, the valve stem end can have 2-4 symmetrical claws. The material is preferably wear-resistant. Snap-fit ​​121 and valve stem 12 can be integrally injection molded, reducing the number of parts.

[0067] Furthermore, such as Figure 4 As shown, the valve body 1 also includes a first elastic element 15. One end of the first elastic element 15 is connected to the valve stem 12, and the other end of the first elastic element 15 is connected to the bracket 11. The first elastic element 15 is in an elastic compression or elastic tension state, so as to elastically drive the valve stem 12 to drive the sealing element 13 to have a tendency to move closer to the bracket 11, so that the sealing element 13 closes the water passage hole 111.

[0068] Specifically, in one embodiment, the first elastic element 15 can be a spring or a tension spring. When the first elastic element 15 is a spring, it is in an elastically compressed state, elastically driving the valve stem 12 to move the sealing element 13 closer to the bracket 11, thereby closing the water passage hole 111. When the first elastic element 15 is a tension spring, it is in an elastically stretched state, elastically driving the valve stem 12 to move the sealing element 13 closer to the bracket 11, thereby closing the water passage hole 111. The first elastic element 15 can be selected according to actual design requirements.

[0069] The first elastic element 15 acts as a driving medium, connecting the fixed point of the bracket 11 with the moving point of the valve stem 12, providing a continuous restoring force, and ensuring that the sealing element 13 is in a closed state of the water passage 111 by the action of the first elastic element 15 when no other force is applied. The first elastic element 15 can be a helical spring, a butterfly spring, or a rubber spring, etc.

[0070] Furthermore, the first elastic element 15 is pre-compressed or pre-stretched to store potential energy, so that the valve stem 12 is always driven by a unidirectional force to tend towards the closed position, thereby improving reliability.

[0071] Furthermore, such as Figure 4 and Figure 5 As shown, in one embodiment, the valve body 1 further includes a mounting bracket 16 connected to the bracket 11. The mounting bracket 16 is fitted over the cooling and insulation cup and is sealed to the cup opening.

[0072] The mounting bracket 16 serves as a transition structure, extending the fixed base of the valve stem 12. By sleeved onto the outside of the cup, it utilizes the cup mouth reference surface to achieve precise positioning and sealing. The sleeved design can distribute the weight of the valve body, avoiding stress concentration at the weak point of the cup mouth. This overcomes the problems that may occur when the valve stem 12 is directly installed inside the cup, such as poor sealing due to cup wall tolerances, the need for tools for disassembly and assembly, and inconvenience for cleaning.

[0073] It should be noted that, in one embodiment, the mounting bracket 16 and the support 11 are integrally molded by injection molding to improve structural stability. The cooling and insulated cup also includes a cup lid 5, which is threadedly connected to the mounting bracket 16 of the valve body 1 at the mouth of the cooling and insulated cup to close or open the cooling and insulated cup.

[0074] The lid 5 and the mounting bracket 16 are connected by threads, making it easy to disassemble and clean the cooling and insulated cup, thus improving cleaning efficiency. The threaded connection between the mounting bracket 16 and the mouth of the cooling and insulated cup provides mechanical locking force, ensuring that the lid 5 and the mounting bracket 16 are tightly engaged, achieving a secondary seal, and the threaded connection facilitates manual operation.

[0075] Furthermore, the control element 2 is reciprocatingly inserted through the cup lid 5 along the cup depth direction and is sealed with the cup lid 5 to prevent water from overflowing through the gap at the connection between the control element 2 and the cup lid 5 during the operation of the control element 2. Specifically, the part of the control element 2 located inside the cooling and insulated cup abuts against the valve stem 12 along the cup depth direction. When the control element 2 moves inward along the cup depth direction into the cooling and insulated cup, it can drive the valve stem 12 to move the sealing element 13 synchronously to open the water passage 111.

[0076] The control component 2 is reciprocatingly inserted into the cup lid 5 along the cup depth direction. This insertion design ensures linear movement of the control component 2, reducing energy loss, and the sealing fit prevents liquid leakage from the cup through gaps in the control component. The portion of the control component 2 located inside the cooling and insulated cup abuts against the valve stem 12 along the cup depth direction, achieving point-to-point transmission. Operating force is directly transmitted, resulting in rapid response and a simple, reliable structure. In summary, the control component 2, inserted into the cup lid 5 and directly abutting against the valve stem 12, simplifies the transmission chain and improves the operating feel; simultaneously, the sealing fit ensures the overall sealing of the cup body.

[0077] like Figure 7 As shown, in one embodiment, the control element 2 includes a pressing part 21, a pushing part 23 and a connecting part 22. The connecting part 22 connects the pressing part 21 and the pushing part 23 and is reciprocally movable through the cup lid 5 along the cup depth direction. The pressing part 21 is located on the outside of the cup lid 5, and the pushing part 23 is located on the inside of the cup lid 5 and abuts against the valve stem 12 along the cup depth direction.

[0078] It should be noted that the outer side of the cup lid 5 refers to the area outside the cup lid 5's receiving space, while the inner side of the cup lid 5 refers to the area inside the cup lid 5's receiving space.

[0079] The control component 2 features a split design to achieve functional separation: the pressing part 21 receives user input, the pushing part 23 directly drives the valve stem 12, and the connecting part 22 ensures structural integrity and transmits driving force. The pressing part 21 can be designed with a large contact surface for easy pressing, while the pushing part 23 can have a smaller focal point. The diameter of the connecting part can be between the two, or smaller than the pushing part 23, as long as it provides structural stability in the operating environment. For example, the pressing part 21 can have a diameter of 15-20 mm, the pushing part 23 a diameter of 5 mm, and the connecting part 22 a diameter of 3 mm.

[0080] Furthermore, when the control element 2 moves into the thermos cup along the cup depth direction, the push part 23 abuts against the valve stem 12 along the cup depth direction, thereby opening the water passage 111.

[0081] The control element 2 may also include a second elastic element 24. One end of the second elastic element 24 is connected to the cup lid 5, and the other end of the second elastic element 24 is connected to the pressing part 21. The second elastic element 24 is in an elastic compression or elastic stretching state, so as to elastically drive the pressing part 21 to have a tendency to move away from the cup lid 5, so that the pressing part 21 can rebound and reset after being pressed inward to the cup lid 5.

[0082] The second elastic element 24 can be a spring or a tension spring. When the second elastic element 24 is a spring, it is in an elastically compressed state, elastically driving the pressing part 21 to move away from the cup lid 5, so that the pressing part 21 can spring back to its original position after being pressed inwards towards the cup lid 5. When the second elastic element 24 is a tension spring, it is in an elastically stretched state, elastically driving the pressing part 21 to move away from the cup lid 5, so that the pressing part 21 can spring back to its original position after being pressed inwards towards the cup lid 5. The second elastic element 24 can be selected according to actual design requirements. The second elastic element 24 provides automatic rebound force, ensuring that the control element 2 returns to its initial position after each press, realizing one-button operation.

[0083] Based on the same concept, this application provides a cooling and insulated cup, including a control component 2 and a valve body 1 as described in any of the above embodiments. The control component 2 is disposed on the outside of the cooling and insulated cup and is drivenly connected to the valve stem 12. The specific positions of the control component 2 and the cooling and insulated cup can be adaptively adjusted according to actual design requirements.

[0084] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
