Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a suction tube, a water nozzle and a water bottle that can prevent scalding during sucking. Background Art

[0002] A water bottle is a common liquid container for storing water during outdoor or outdoor activities. The water can be drinking water, beverages, liquid food or other liquids. Generally, a water nozzle or a suction tube for facilitating users to suck the water in the water bottle is equipped on the water bottle. Users can suck the water in the water bottle through the water nozzle or the suction tube to meet the needs of their growth and development or functional preferences. Usually, during the use of the water bottle, users need to add hot water to the water bottle, or mix hot water with powder, dissolve the powder in the water bottle with hot water, or users heat breast milk through a heating device and pour the heated breast milk into the water bottle. The above operation methods all bring liquids with a certain amount of heat into the water bottle for feeding or drinking. However, these methods require users to always pay attention to the temperature change of the liquid.

[0003] Currently, the actual temperature of the liquid can usually be detected by a thermometer, a fever probe or directly touching the outer side of the water bottle with the user's hand skin feeling. However, obtaining the real-time temperature through tools such as a thermometer or a fever probe requires a relatively cumbersome process of taking out and putting away the tools, and the user's hand skin feeling is prone to temperature perception deviation. When the user directly sucks the water in the water bottle through the water nozzle or the suction tube, the scalding water directly enters the user's mouth through the water nozzle or the suction tube. If the temperature is too high, it may scald the user's mouth, and it is difficult for the user to stop the flow of the liquid in time, seriously affecting the safety of the user's drinking or sucking.

[0004] In view of the above deficiencies, we need to develop a suction tube that can prevent scalding during sucking to meet the usage needs of the majority of users. Summary of the Utility Model

[0005] In view of the problems mentioned above, such as the existing temperature detection means being relatively cumbersome and it being difficult for users to stop the flow of the liquid into the mouth in time when there is a temperature perception deviation, the technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] A suction tube that can prevent scalding during sucking includes a tube body and an anti-scalding component installed on the tube body. The tube body is provided with a hollow tube channel. The anti-scalding component includes a mounting shell for being arranged on the tube body and a deformation member for overheating and expanding and deforming. The deformation member is located in the inner cavity of the mounting shell. At least two channel openings communicating with the outside are opened in the inner cavity of the shell. The tube channel communicates with one of the channel openings, so that the tube channel communicates with the inner cavity of the shell.

[0007] Further, the installation housing includes a first installation housing and a second installation housing. The first installation housing and the second installation housing are cooperatively connected to form the inner cavity of the housing. One channel opening of the inner cavity of the housing penetrates through the first installation housing to form a first channel, and the other channel opening of the inner cavity of the housing penetrates through the second installation housing to form a second channel.

[0008] Further, a first limiting member is disposed between the deformable member and the first channel, and a second limiting member is disposed between the deformable member and the second channel. The pipe channel communicates with the first channel or the second channel. The deformable member can expand and deform in a superheated state and press against the inner wall of the inner cavity of the housing.

[0009] Further, the deformable member includes a deformable metal and an elastic soft rubber layer for wrapping the outside of the deformable metal. The deformable metal maintains a curled shape below the deformation critical temperature and transforms into an unfolded shape above the deformation critical temperature.

[0010] Further, the deformable member is located between the first channel and the second channel. The outer diameter of the deformable member at normal temperature is respectively greater than the diameters of the first channel and the second channel, and less than the maximum inner diameter of the inner cavity of the housing.

[0011] Further, one of the first installation housing and the second installation housing is integrally formed with the pipe body.

[0012] Further, the deformable metal is made of nitinol alloy.

[0013] Further, a water nozzle includes a sucking part and a clamping part. The clamping part is used for installing the suction pipe. One end of the pipe body away from the anti-scalding component is provided with an integrally formed fitting pipe head. A sucking inner cavity is formed between the sucking part and the clamping part. The fitting pipe head extends into the sucking inner cavity and is detachably connected to the clamping part. A water suction port penetrating through the sucking part is provided on one side of the sucking inner cavity away from the clamping part. The pipe channel passes through the fitting pipe head to communicate with the sucking inner cavity.

[0014] Further, the clamping part is provided with a first convex part and a second convex part. The fitting pipe head is provided with a first concave part for cooperating with the first convex part. Rounded curved surface structures for facilitating installation are provided on both axial sides of the fitting pipe head located at the first concave part.

[0015] Furthermore, a water bottle includes a bottle body and a bottle cap detachably connected to the bottle body. The bottle body is provided with a water storage cavity for storing water. An inlet communicating with the outside is formed on one side of the bottle cap away from the bottle body. The inlet communicates with the water storage cavity. The inlet is detachably connected to a water nozzle. The tube body communicates with the water storage cavity of the bottle body through the anti-scalding component.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. In the present utility model, a deformable member capable of overheating and expanding and deforming is adopted in the suction tube. When the water with too high temperature is sucked into the anti-scalding component, the water flows through the inner cavity of the shell and contacts the deformable member. The temperature of the water is transferred to the deformable member, causing the deformable member to overheat, expand and deform. The outer side of the expanded and deformed deformable member contacts the inner wall of the inner cavity of the shell to achieve the blocking effect. The deformable member prevents the water with too high temperature from continuing to flow. The water that has flowed through the deformable member also cannot continue to flow towards the user's oral cavity due to the blocking effect of the deformable member, realizing timely prevention of the water with too high temperature from flowing into the user's oral cavity. There is no need to borrow external tools and skin feeling for temperature measurement. The overheat feedback response is rapid. The overall structure is simple, the production and installation are convenient, and the manufacturing cost is reduced.

[0018] 2. The deformable member of the present utility model wraps the deformable metal with a soft rubber layer, so that the deformable metal does not directly contact the water, avoiding polluting the quality of the water. The deformable metal adopts a shape memory alloy nickel-titanium alloy. Nickel-titanium alloy has good reset elasticity within a certain temperature range, can undergo large elastic deformation without permanent deformation, and can return to its original shape when the external temperature difference is removed. The position of the deformable member is limited by the first limiting member and the second limiting member, avoiding the deformable member from being blocked in the tube channel due to flowing with the water at normal temperature. It is suitable for scenarios with high frequency of temperature changes such as repeated injection and consumption of water in the water bottle. Nickel-titanium alloy can be used repeatedly for many times, improving the practicability and durability of the product and facilitating the use of users.

[0019] 3. The present utility model applies a suction tube for preventing scalding during sucking to the water nozzle, further expanding the applicable scenarios for preventing scalding during sucking. The water nozzle and the suction tube are high-frequency utensils for facilitating the drinking of the water bottle. Combining the suction tube with the water nozzle can further promote the effect of preventing scalding during sucking. The suction tube is detachably connected to the clamping part of the water nozzle by a matching tube head, increasing the replaceability of the water nozzle and the suction tube, facilitating the user to apply the suction tube for preventing scalding during sucking to water nozzles with different shapes, and also facilitating the user to disassemble and clean to prevent bacteria from breeding inside the water nozzle and the suction tube, further improving the cleanability and reusability of the water nozzle and the suction tube and facilitating the use of users.

[0020] 4. The utility model applies a detachable water nozzle to the water bottle and an anti-suction scalding straw to the water nozzle, further expanding the applicable scenarios for preventing suction scalding. The water bottle, water nozzle, and straw are all high-frequency utensils for convenient drinking from the water bottle. Combining the straw with the water bottle can further promote the effect of preventing suction scalding. The bottle cap is detachably connected to the water nozzle, increasing the replaceability of the water nozzle and the straw, facilitating users to apply the anti-suction scalding straw to different styles of water bottles, and also facilitating users to disassemble and clean to prevent bacteria from breeding inside the bottle body, bottle cap, water nozzle, and straw, further improving the cleanability and reusability of the water bottle product and facilitating user use.

[0033] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0034] As Figures 1 to 8 shown, an esophageal tube that can prevent scalding during sucking, includes a tube body 100 and a scald prevention component 200 installed on the tube body 100. The tube body 100 is provided with a hollow tube channel 11. The scald prevention component 200 includes a mounting shell 20 for being arranged on the tube body 100 and a deformation member 23 for thermally expanding and deforming. The deformation member 23 is located in the inner cavity 24 of the mounting shell 20. At least two openings communicating with the outside are formed in the inner cavity 24 of the shell. The tube channel 11 communicates with one of the openings, so that the tube channel 11 communicates with the inner cavity 24 of the shell.

[0035] Optionally, in some embodiments, the deformable part of the deformation member 23 can be made of materials such as nickel-titanium alloy, copper-zinc alloy, copper-aluminum alloy, gold-copper alloy, silver-iron alloy, etc. as the material for thermal deformation.

[0036] Optionally, in some embodiments, the tube body 100 can be made of materials such as plastic, plastic, rubber, silica gel, glass or polymer materials.

[0037] Specifically, in some embodiments, the tube body 100 is a hollow pipe for the main flow of water and liquid in the esophageal tube. The tube body 100 can use a food safety grade silica gel hose or a plastic hard tube as the main structure. Preferably, the tube body 100 uses a silica gel hose as the main structure, so as to be naturally bent under the influence of the gravity of the scald prevention component 200. When the user changes the posture, the scald prevention component 200 can always fall into the water and liquid affected by natural gravity, and the user can suck smoothly. The scald prevention component 200 can play the role of a gravity ball. One side of the mounting shell 20 is fixedly connected or integrally formed with the tube body 100. The water and liquid enter from the other side of the mounting shell 20. The scald prevention component 200 uses the mounting shell 20 to wrap and enclose to form an inner cavity 24 for accommodating the deformation member 23, which not only restricts the moving position of the deformation member 23, but also facilitates the flow of water and liquid for the user to eat. When the deformation member 23 thermally expands and deforms, the spiral elastic structure can press against the deformation member 23 so that the deformation member 23 extends and expands from a position other than the compressed position, and finally presses against the inner wall of the inner cavity 24 of the shell to achieve the effect of blocking and stopping the flow;

[0038] Preferably, in this embodiment, the deformable member 23 adopts a deformation assembly including shape memory metal nickel-titanium alloy. The shape memory metal nickel-titanium alloy plays a role of thermal deformation in the deformable member 23. The outer material of the deformable member 23 has a good waterproof and sealing effect. The outer material of the deformable member 23 wraps the shape memory metal nickel-titanium alloy so that the deformable member 23 can prevent liquid from flowing through after heating and expanding. Nickel-titanium alloy has good reset elasticity within a certain temperature range, can undergo large elastic deformation without permanent deformation, and can return to its original shape when the external temperature difference is removed. It is suitable for scenarios with a high frequency of temperature changes such as repeated injection and consumption of water in a water bottle. The pipe channel 11 communicates with the inner cavity 24 of the housing. The water can enter the inner cavity 24 of the housing from the other side of the mounting housing 20. When in use, when the user sucks and eats from the end of the pipe body 100 away from the anti-scalding component 200, sucking the pipe body 100 with the mouth causes the water to be sucked into the anti-scalding component 200 via the pipe body 100 by the pressure difference. More specifically, the water is affected by the pressure difference generated by sucking and enters the inner cavity 24 of the housing from the other side of the mounting housing 20, flows through the deformable member 23 in the inner cavity 24 of the housing and flows towards the pipe channel 11 to the user's mouth, realizing the normal eating function;

[0039] When the sucked water has too high a temperature, the heat of the water flowing through the inner cavity 24 of the housing is transferred to the deformable member 23 after contacting the deformable member 23. The deformable member 23 undergoes a phase change effect and expands and deforms due to overheating. More specifically, the deformable member 23 can undergo deformation caused by the phase change effect in an environment of a certain temperature. This temperature at which the deformation occurs can be called the phase change critical temperature. When the deformable member 23 is in a state above the phase change critical temperature, it can be called an overheated state. Preferably, in this embodiment, the phase change critical temperature of the deformable member 23 is between 38 degrees and 40 degrees. Water flowing through the deformable member 23 outside this temperature range will induce the phase change effect of the deformable member 23. The outer side of the deformable member 23 expands sufficiently and presses against the wall of the inner cavity 24 of the housing. The deformable member 23 expands to block the inner cavity 24 of the housing, making the water that has not flowed through the deformable member 23 unable to continue flowing. At the same time, the water that has flowed through the deformable member 23 also cannot continue flowing due to blocking the mounting housing 20, achieving the effect of preventing overheated water from flowing to the user's mouth, timely blocking the flow of water with too high a temperature, without borrowing external tools and skin feeling for temperature measurement, having a rapid overheat feedback response, a simple overall structure, convenient production and installation, and reducing the production cost.

[0040] As Figures 1 to 8 shown in a drinking straw that can prevent scalding during sucking, the mounting housing 20 includes a first mounting housing 21 and a second mounting housing 22. The first mounting housing 21 and the second mounting housing 22 are cooperatively connected to form the inner cavity 24 of the housing. One channel opening of the inner cavity 24 penetrates through the first mounting housing 21 to form a first channel 211, and the other channel opening of the inner cavity 24 penetrates through the second mounting housing 22 to form a second channel 221.

[0041] Specifically, in some embodiments, the installation housing 20 adopts a split structure and is divided into a first installation housing 21 and a second installation housing 22. The first installation housing 21 and the second installation housing 22 can respectively adopt a semi-circular hollow thin-walled structure. The anti-scalding component 200 uses the first installation housing 21 and the second installation housing 22 to wrap and enclose to form an inner cavity 24 of the installation housing 20 for accommodating the deformable member 23. The inner cavity 24 of the housing penetrates through the first installation housing 21 to form a first channel 211, and the inner cavity 24 of the housing penetrates through the second installation housing 22 to form a second channel 221. The first installation housing 21 and the second installation housing 22 are assembled to form the installation housing 20 in the form of snap connection or fitting connection. One of the first installation housing 21 and the second installation housing 22 is formed on the pipe body 100, and the other of the first installation housing 21 and the second installation housing 22 allows the water liquid to flow in, which is convenient for the manufacture and installation of the installation housing 20 and the flow of water liquid.

[0042] Preferably, in this embodiment, the pipe channel 11 communicates with the first channel 211 so that the pipe channel 11 communicates with the inner cavity 24 of the housing. The water liquid can enter the inner cavity 24 from the second channel 221. When in use, when the user sucks and eats from the end of the pipe body 100 away from the anti-scalding component 200, the oral cavity sucks the pipe body 100 so that the water liquid is sucked into the anti-scalding component 200 through the pipe body 100 and enters the oral cavity by using the pressure difference. More specifically, the water liquid is affected by the pressure difference generated by sucking and enters the inner cavity 24 from the second channel 221, flows through the deformable member 23 in the inner cavity 24 and flows towards the first channel 211. The water liquid enters the pipe channel 11 through the first channel 211 and flows towards the user's oral cavity, realizing the normal eating function.

[0043] Specifically, in some embodiments, the pipe channel 11 can also communicate with the second channel 221 so that the pipe channel 11 communicates with the inner cavity 24 of the housing. The water liquid can enter the inner cavity 24 from the first channel 211. When in use, when the user sucks and eats from the end of the pipe body 100 away from the anti-scalding component 200, the oral cavity sucks the pipe body 100 so that the water liquid is sucked into the anti-scalding component 200 through the pipe body 100 and enters the oral cavity by using the pressure difference. When the sucked water liquid has too high a temperature, the deformable member 23 undergoes a phase change effect due to overheating and expands and deforms to block the inner cavity 24 of the housing, so that the water liquid cannot continue to flow, achieving the effect of preventing the overheated water liquid from flowing towards the user's oral cavity, timely blocking the flow of the water liquid with too high a temperature, without borrowing external tools and skin feeling temperature measurement, having a rapid overheat feedback response, using the first limiting member 25 and the second limiting member 26 to limit the position of the deformable member, and avoiding the deformable member 23 from blocking the pipe channel 11 due to flowing with the water liquid at normal temperature. The overall structure is simple, the production and installation are convenient, and the manufacturing cost is reduced.

[0044] Such as Figures 5 to 7A suction tube that can prevent scalding during suction. A first limiting member 25 is provided between the deformable member 23 and the first channel 211, and a second limiting member 26 is provided between the deformable member 23 and the second channel 221. The tube channel 11 communicates with the first channel 211 or the second channel 221. The deformable member 23 can expand and deform in a superheated state and press against the wall 241 of the inner cavity 24 of the housing.

[0045] Specifically, in some embodiments, the first limiting member 25 is provided between the deformable member 23 and the first channel 211 to limit the direction of the deformable member 23 following the water flow to the first channel 211 to prevent the deformable member 23 from blocking the first channel 211. The second limiting member 26 is provided between the deformable member 23 and the second channel 221 to limit the direction of the deformable member 23 following the water flow to the second channel 221 to prevent the deformable member 23 from blocking the second channel 221. The first limiting member 25 and the second limiting member 26 can be made of food-safe metals, plastics, plastics, etc. The first limiting member 25 and the second limiting member 26 can adopt a hollow curved spiral elastic structure, which not only limits the moving position of the deformable member 23, but also facilitates the flow of water for the user to eat. When the deformable member 23 expands and deforms due to overheating, the spiral elastic structure can press against the deformable member 23 so that the deformable member 23 expands and extends from a position other than the compressed position, and finally presses against the wall of the inner cavity 24 of the housing to achieve the effect of blocking and stopping the flow.

[0046] When the suctioned water is too hot, the heat of the water flowing through the inner cavity 24 of the housing is transferred to the deformable member 23 after contacting the deformable member 23. The deformable member 23 undergoes a phase change due to overheating and expands and deforms. More specifically, the deformable member 23 can undergo deformation due to a phase change in an environment at a certain temperature. This temperature at which deformation occurs can be called the phase change critical temperature. When the deformable member 23 is in a state above the phase change critical temperature, it can be called a superheated state. Preferably, in this embodiment, the phase change critical temperature of the deformable member 23 is between 38 degrees and 40 degrees. Water flowing through the deformable member 23 outside this temperature range will induce a phase change of the deformable member 23. The outer side of the deformable member 23 expands fully and presses against the wall of the inner cavity 24 of the housing. The deformable member 23 expands to block the inner cavity 24 of the housing, so that the water that has not flowed through the deformable member 23 cannot continue to flow. At the same time, the water that has flowed through the deformable member 23 is also blocked, making the first channel 211 and the second channel 221 not communicate and unable to continue flowing, achieving the effect of preventing overheated water from flowing to the user's mouth, promptly stopping the flow of water at too high a temperature, without borrowing external tools and skin feeling for temperature measurement, with a rapid overheat feedback response. Using the first limiting member 25 and the second limiting member 26 to limit the position of the deformable member 23, avoiding the deformable member 23 blocking the tube channel 11 due to flowing with the water in the normal temperature state. The overall structure is simple, the production and installation are convenient, and the manufacturing cost is reduced.

[0047] Such asFigure 9 and Figure 10 A suction tube that can prevent scalding during suction as shown. The deformable member 23 includes a deformable metal 231 and an elastic soft rubber layer 232 for wrapping around the outside of the deformable metal 231. The deformable metal 231 maintains a curled shape below the deformation critical temperature, and the deformable metal 231 transforms into an unfolded shape above the deformation critical temperature.

[0048] Optionally, in some embodiments, the deformable metal 231 can use materials such as nickel-titanium alloy, copper-zinc alloy, copper-aluminum alloy, gold-copper alloy, silver-iron alloy, etc. as the materials for heat-induced deformation.

[0049] Optionally, in some embodiments, the elastic soft rubber layer 232 can use materials such as polyethylene, polypropylene, polyethylene terephthalate, polyurethane, polystyrene, silica gel, rubber, etc. that have good elastic deformation and good chemical stability.

[0050] Specifically, in some embodiments, the deformable metal 231 uses a nickel-titanium alloy as the material for heat-induced deformation. The nickel-titanium alloy has good reset elasticity within a certain temperature range, can undergo large elastic deformation without permanent deformation, and can return to its original shape when the external temperature difference is removed. It is suitable for scenarios with a relatively high frequency of temperature changes such as repeated injection and consumption of water in a water bottle.

[0051] The deformation critical temperature of the deformable metal 231 is also the phase change critical temperature. The critical temperature range is set between 30 degrees and 40 degrees. When the deformable metal 231 is in a state above the deformation critical temperature, it can be called an overheated state. When the deformable metal 231 is in a state below the deformation critical temperature, it can be called a normal temperature state. The deformable metal 231 is in a curled shape with a spiral structure at the normal temperature state. The outside of the deformable metal 231 is completely wrapped and sealed by the elastic soft rubber layer 232 into a spherical shape or an elliptical spherical shape. The elastic soft rubber layer 232 uses a thin film structure with a thickness controlled below 3 mm. The deformable metal 231 will transform the spiral structure into an unfolded shape in the overheated state.

[0052] When the environmental temperature of the deformable metal 231 enters the interval of the critical temperature range, phase change occurs, resulting in deformation. The deformation requires a certain temperature increase process, that is, the deformation starts from the environmental temperature of 30 degrees, and the maximum deformation is achieved when the environmental temperature reaches 40 degrees, realizing blockage. More specifically, during the process of unfolding the coiled structure, the deformable metal 231 continuously presses against the elastic soft rubber layer 232 located outside the deformable metal 231, causing the elastic soft rubber layer 232 to expand and stretch elastically until the elastic soft rubber layer 232 presses against the inner cavity 24 of the shell and fully blocks the flow cross-section of the inner cavity 24 of the shell. The water liquid cannot flow through the space sealed by the elastic soft rubber layer 232, achieving the effect of preventing overheated water liquid from flowing to the user's oral cavity, timely preventing the flow of water liquid with too high temperature, without borrowing external tools and skin feeling temperature measurement, and having a rapid overheat feedback response. The positions of the deformable member 23 are restricted by the first limiting member 25 and the second limiting member 26 to avoid the deformable member 23 blocking the pipe channel due to flowing with the water liquid at normal temperature. The overall structure is simple, the production and installation are convenient, and the manufacturing cost is reduced.

[0053] Such as Figure 6 and Figure 7 As shown in a straw that can prevent scalding during sucking, the first channel 211 is located on the side of the first mounting shell 21 away from the second mounting shell 22, the second channel 221 is located on the side of the second mounting shell 22 away from the first mounting shell 21, and the first channel 211 and the second channel 221 are coaxially arranged.

[0054] Specifically, in some embodiments, the water in the first channel 211 is generally affected by natural gravity and easily accumulates at the bottom of the water storage cavity 41. To further facilitate the user to suck the water at the bottom of the water storage cavity 41, the relative positions of the first channel 211 and the second channel 221 are adjusted to enable the user to easily suck the water. More specifically, the tube body 100 extends from the orifice of the water storage cavity 41 communicating with the outside world, that is, located at the top of the water storage cavity 41. The position where the anti-scalding component 200 is provided on the tube body 100 is at the end of the tube body 100, and generally needs to extend to the bottom of the water storage cavity 41 to facilitate the user to suck. Preferably, in this embodiment, the tube body 100 connects the tube channel 11 to the inner cavity 24 of the housing via the first channel 211. The second channel 221 is provided on the side of the second mounting housing 22 away from the first mounting housing 21, so that the position of the second channel 221 is set at the farthest place from the first channel 211, that is, the closest to the bottom of the water storage cavity 41, facilitating the user to suck the water at the bottom of the water storage cavity 41. The first channel 211 and the second channel 221 are coaxially arranged, which can further ensure the smooth flow of the water. Compared with the non-coaxial arrangement, when the water flows through the inner cavity 24 of the housing, the water enters from the second channel 221 and flows in the axial direction towards the first channel 211, without the need for corner flow. The water can also fully contact the deformable member 23, enabling the deformable member 23 to be fully heated and timely sense the water temperature to quickly make a blocking reaction.

[0055] Specifically, in some embodiments, the tube body 100 can also connect the tube channel 11 to the inner cavity 24 of the housing via the second channel 221. The first channel 211 is provided on the side of the first mounting housing 21 away from the second mounting housing 22, so that the position of the first channel 211 is set at the farthest place from the second channel 221, that is, the closest to the bottom of the water storage cavity 41, facilitating the user to suck the water at the bottom of the water storage cavity 41. When the water flows through the inner cavity 24 of the housing, the water enters from the first channel 211 and flows in the axial direction towards the second channel 221, without the need for corner flow. The water can also fully contact the deformable member 23, enabling the deformable member 23 to be fully heated and timely sense the water temperature to quickly make a blocking reaction.

[0056] As Figure 6 and Figure 7 shown in a straw that can prevent scalding during sucking, the deformable member 23 is located between the first channel 211 and the second channel 221. The outer diameter of the deformable member 23 in the normal temperature state is respectively larger than the diameters of the first channel 211 and the second channel 221, and smaller than the maximum inner diameter of the inner cavity 24 of the housing.

[0057] Specifically, in some embodiments, to prevent the deformable member 23 from flowing out of the inner cavity 24 of the housing along with the water liquid through the first channel 211 or the second channel 221 at normal temperature, the outer diameter of the deformable member 23 at normal temperature is greater than the inner diameter of the first channel 211, and the outer diameter of the deformable member 23 at normal temperature is also greater than the inner diameter of the second channel 221. Whether the pipe body 100 communicates with the inner cavity 24 through the first channel 211 or the second channel 221, the deformable member 23 will not be taken out of the inner cavity 24 by the suction force sucked by the user, so as to avoid potential safety hazards caused by the user accidentally sucking the deformable member 23. The deformable member 23 will not be washed out of the inner cavity 24 by the backflowing water liquid and enter the water storage cavity 41, so as to avoid losing the function of preventing scalding. On this basis, the outer diameter of the deformable member 23 at normal temperature is less than the maximum inner diameter of the inner cavity 24 of the housing, so as to leave enough space for the water liquid to flow through the inner cavity 24 of the housing for the deformable member 23, ensure that the water liquid can smoothly pass through the inner cavity 24 at normal temperature, ensure the normal water liquid flow rate, and ensure the user can normally suck the water liquid.

[0058] More specifically, since the contact connection between the first mounting housing 21 and the second mounting housing 22 is located in the middle of the anti-scalding assembly 200, the deformable member 23 is arranged at the position between the first channel 211 and the second channel 221. When undergoing overheat expansion and deformation, the deformable member 23 can use the top pressure generated by the expansion to simultaneously seal the contact gap between the first mounting housing 21 and the second mounting housing 22, preventing the overheated water liquid outside the anti-scalding assembly 200 from entering the pipe channel 11 through the contact gap between the first mounting housing 21 and the second mounting housing 22 and scalding the user's oral cavity.

[0059] As Figure 7 shown in a straw that can prevent scalding by sucking, one side of the first mounting housing 21 close to the second mounting housing 22 is provided with a first mounting plane 212, one side of the second mounting housing 22 close to the first mounting housing 21 is provided with a second mounting plane 222, one of the first mounting plane 212 and the second mounting plane 222 is provided with a protruding snap portion 27, and the other of the first mounting plane 212 and the second mounting plane 222 is provided with a recessed clamping portion 28. The snap portion 27 extends into the clamping portion 28 for snap connection so that the first mounting plane 212 and the second mounting plane 222 are attached.

[0060] Specifically, in some embodiments, to facilitate the installation and fitting between the first installation housing 21 and the second installation housing 22, the first installation housing 21 and the second installation housing 22 can be made of food-safe rigid plastic. The first installation housing 21 and the second installation housing 22 are installed in a snap-fit connection. On one side of the first installation housing 21 close to the second installation housing 22, there is a first installation plane 212. On one side of the second installation housing 22 close to the first installation housing 21, there is a second installation plane 222. Preferably, in this embodiment, the protruding snap portion 27 is located on the second installation plane 222, and the recessed clamping portion 28 is located on the first installation plane 212. During installation, the snap portion 27 is aligned and inserted into the clamping portion 28, so that the limiting convex hook of the snap portion 27 is snapped into the limiting concave pit of the clamping portion 28. After the snap portion 27 is inserted into the clamping portion 28, the first installation plane 212 and the second installation plane 222 are flat and fitted together. The elastic tightening of the material between the snap portion 27 and the clamping portion 28 is used to ensure that the inflow of water and liquid from the gap between the first installation plane 212 and the second installation plane 222 outside the anti-scalding component 200 is reduced.

[0061] As Figures 1 to 5 shown in a straw that can prevent scalding during sucking, one of the first installation housing 21 and the second installation housing 22 is integrally formed with the tube body 100.

[0062] Specifically, in this embodiment, the first installation housing 21 is integrally formed at one end of the tube body 100 and is made of the same material. Water and liquid enter the inner cavity 24 of the housing from the second installation housing 22, meeting the requirements of national standards. At the same time, the number of component assembly steps is reduced, and the situation of the installation housing 20 loosening and falling off is avoided, which is convenient for users to use.

[0063] Specifically, in this embodiment, the second installation housing 22 is integrally formed at one end of the tube body 100 and is made of the same material. Water and liquid enter the inner cavity 24 of the housing from the first installation housing 21, meeting the requirements of national standards. At the same time, the number of component assembly steps is reduced, and the situation of the installation housing 20 loosening and falling off is avoided, which is convenient for users to use.

[0064] As Figure 11 and Figure 12 shown in a straw that can prevent scalding during sucking, a protruding tube fitting portion is provided on the outer side of the tube body 100. The first channel 211 or the second channel 221 extends away from the inner cavity 24 of the housing to form a channel installation structure 29, and a recessed channel fitting portion 291 is provided in the channel installation structure 29. The channel fitting portion 291 is detachably connected to the tube fitting portion 12.

[0065] Specifically, in some embodiments, the tube body 100 is made of a food-safe silicone hose. The texture of the silicone is relatively soft. At one end of the tube body 100 close to the anti-scalding component 200, a tube fitting portion 12 with a semi-circular protrusion is arranged in a direction away from the tube channel 11. The tube fitting portions 12 are arranged at least two at intervals along the length direction of the tube body 100 in a circular ring shape. Preferably, in this embodiment, the tube body 100 extends the tube channel 11 into the first channel 211 to communicate with the inner cavity 24 of the housing. Therefore, a channel installation structure 29 is arranged at a position of the first channel 211 close to the tube body 100. The channel installation structure 29 is hollow and communicates with the first channel 211. On the inner hole wall of the channel installation structure 29, there is a channel fitting portion 291 with a semi-circular depression for fitting and installing the tube fitting portion 12. One end of the tube body 100 close to the anti-scalding component 200 extends into the channel installation structure 29, so that the protruding tube fitting portion 12 is fitted and connected to the sunken channel fitting portion 291. By utilizing the characteristics of the relatively soft silicone material, an elastic snap connection form is realized. The design of the semi-circular protrusion and depression can facilitate insertion and extraction, improving the convenience of product installation and disassembly. The elasticity of the silicone material enables the protruding tube fitting portion 12 to fully press against the surface of the sunken channel fitting portion 291, achieving a certain degree of elastic sealing effect, so that the water liquid cannot enter the tube channel 11 through the channel installation structure 29 outside the anti-scalding component 200, further avoiding scalding the user's oral cavity.

[0066] Specifically, in some embodiments, the tube body 100 can also extend the tube channel 11 into the second channel 221 to communicate with the inner cavity 24 of the housing. Therefore, a channel installation structure 29 can also be arranged at a position of the second channel 221 close to the tube body 100. This embodiment can play the same role and effect as when the channel installation structure 29 is arranged in the first channel 211.

[0067] Specifically, in some embodiments, at one end of the tube body 100 close to the anti-scalding component 200, two or more tube fitting portions 12 can be arranged at intervals along the axial direction of the tube body 100 in a direction away from the tube channel 11. On the inner hole wall of the channel installation structure 29, two or more channel fitting portions 291 can be arranged at intervals along the axial direction of the channel installation structure 29. Each tube fitting portion 12 has a corresponding channel fitting portion 291 for cooperative use. The cooperative use of multiple tube fitting portions 12 and multiple channel fitting portions 291 further improves the connection stability and firmness between the tube body 100 and the anti-scalding component 200, avoiding the situation of easy detachment, dropping or loosening.

[0068] As Figure 9 and Figure 10 shown in a straw that can prevent scalding during sucking, the deformable metal 231 is made of nickel-titanium alloy.

[0069] Specifically, in some embodiments, the deformable metal 231 is further defined to use a nickel-titanium alloy. The deformable metal 231 uses a nickel-titanium alloy as the material that deforms when heated. The nickel-titanium alloy has good reset elasticity within a certain temperature range, can undergo large elastic deformations without permanent deformation, and can return to its original shape when the external temperature difference is removed. It is suitable for scenarios with a high frequency of temperature changes such as repeated injection and consumption of water in a water bottle. The deformable metal 231 is in a curled state with a spiral curled structure at room temperature. The outside of the deformable metal 231 is completely wrapped and sealed by an elastic soft rubber layer 232 to form a spherical or elliptical sphere. The elastic soft rubber layer 232 uses a thin film structure with a thickness controlled below 3 mm. When the deformable metal 231 is in an overheated state, it will transform the spiral curled structure into an unfolded form. During the process of unfolding the curled structure, the deformable metal 231 continuously presses against the elastic soft rubber layer 232 located outside the deformable metal 231, causing the elastic soft rubber layer 232 to elastically expand and stretch until the elastic soft rubber layer 232 presses against the inner cavity 24 of the shell and fully blocks the flow cross-section of the inner cavity 24 of the shell. The water liquid cannot flow through the space sealed by the elastic soft rubber layer 232, achieving the effect of preventing overheated water liquid from flowing towards the user's oral cavity, promptly blocking the flow of water liquid with too high a temperature, without the need to borrow external tools and skin-sensing temperature measurement, with a rapid overheat feedback response. The first limiting member and the second limiting member are used to limit the position of the deformable member, avoiding the deformable member from being blocked in the tube channel due to flowing with the water liquid at room temperature. The overall structure is simple, the production and installation are convenient, and the manufacturing cost is reduced.

[0070] Such as Figure 5 and Figure 8 The water nozzle shown in the figure includes a sucking part 31 and a clamping part 32. The clamping part 32 is used to install the suction tube. One end of the tube body 100 away from the anti-scalding component 200 is provided with an integrally formed fitting tube head 13. A sucking inner cavity 33 is formed between the sucking part 31 and the clamping part 32. The fitting tube head 13 extends into the sucking inner cavity 33 and is detachably connected to the clamping part 32. A water suction port 34 penetrating the sucking part 31 is provided on one side of the sucking inner cavity 33 away from the clamping part 32. The tube channel 11 passes through the fitting tube head 13 to communicate with the sucking inner cavity 33.

[0071] Optionally, in some embodiments, the mating nozzle 13 is integrally formed at the end of the tube body 100. Both the water nozzle 300 and the tube body 100 can be made of elastic soft materials such as plastic and silicone. Preferably, both the water nozzle 300 and the tube body 100 are made of food-safe silicone material. Silicone has good elasticity and flexibility, which can help the water nozzle 300 and the tube body 100 to be more easily installed and connected, effectively seal the connection between the water nozzle 300 and the tube body 100, prevent water leakage, and avoid polluting the surrounding living environment. Silicone can withstand high temperatures up to 200°C, and the water nozzle 300 and the tube body 100 can be sterilized at high temperatures together without worrying about deformation or release of harmful substances. The silicone material is not easy to adhere to stains, is relatively easy to clean, saves time and effort. The water nozzle 300 and the tube body 100 made of silicone are easy to mold, can be designed and produced in a variety of styles, and are light in weight, convenient to carry, and suitable for use when going out.

[0072] Specifically, in some embodiments, to further combine the suction tube with the water nozzle for use, the water nozzle 300 adopts a thin-walled elastic design. A sucking portion 31 for the user to suck and bite is provided in the middle of the water nozzle 300. The sucking portion 31 is provided with a hollow sucking inner cavity 33. The sucking inner cavity 33 is formed by enclosing the sucking portion 31 and the clamping portion 32. The sucking inner cavity 33 penetrates through the sucking portion 31 to form a water suction port 34 communicating with the outside world, and the sucking inner cavity 33 penetrates through the clamping portion 32 to form a clamping channel communicating with the outside world. The mating nozzle 13 is located at the end of the tube body 100 away from the anti-scalding component 200 for facilitating connection to the water nozzle 300. The mating nozzle 13 is detachably connected to the clamping portion 32. Both the water nozzle 300 and the mating nozzle 13 are made of food-safe soft silicone. The friction between the soft silicone and the soft silicone enables the tube body 100 to be relatively stably installed on the water nozzle 300. When in use, the user inserts the mating nozzle 13 into the clamping channel, and uses the friction between the soft silicone and the soft silicone to limit the position of the mating nozzle 13 in the clamping portion 32. After one end of the tube body 100 facing the anti-scalding component 200 extends into the water bottle, the water nozzle 300 is then installed on the water bottle, and the user can suck and consume the water liquid.

[0073] As Figure 8 For the water nozzle shown, the clamping portion 32 is provided with a first protrusion 35 and a second protrusion 36. The mating nozzle 13 is provided with a first recess 131 for mating with the first protrusion 35. The mating nozzle 13 is provided with a rounded surface structure 132 for easy installation on the axial two sides of the first recess 131.

[0074] Specifically, in some embodiments, to further facilitate the stable clamping of the fitting pipe head 13 by the clamping portion 32, the clamping portion 32 is provided with a first convex portion 35 and a second convex portion 36 protruding towards the center of the clamping channel on the inner wall of the clamping channel. The fitting pipe head 13 is provided with a first concave portion 131 recessed towards the center. The fitting pipe head 13 extends into the clamping channel from the inlet end. The first convex portion 35 and the second convex portion 36 have different distances from the inlet end of the clamping channel. The first convex portion 35 is located in the middle of the clamping channel to limit the insertion position of the first concave portion 131. The second convex portion 36 is located at the inlet end of the clamping channel to further stabilize the position of the fitting pipe head 13. The first convex portion 35 protrudes in an arc-shaped curved surface, and the first concave portion 131 is recessed in an arc-shaped curved surface. During the insertion process of the fitting pipe head 13 into the clamping channel, after the first convex portion 35 contacts and is connected to the first concave portion 131 and stops inserting, it can be stably installed. More specifically, the fitting pipe head 13 is provided with rounded corner curved surface structures 132 on both axial sides of the first concave portion 131 to facilitate insertion and installation. Compared with a right-angle structure, the rounded corner curved surface structure 132 has better sliding smoothness. Through the rounded corner curved surface contact, it is more convenient for the fitting pipe head 13 to slide into the clamping channel. The rounded corner curved surface structure 132 on the side of the fitting pipe head 13 away from the anti-scalding component 200 pushes open the second convex portion 36. After the first convex portion 35 contacts and is connected to the first concave portion 131 and stops inserting, the rounded corner curved surface structure 132 on the side of the fitting pipe head 13 close to the anti-scalding component 200 contacts the second convex portion 36 to strengthen the relatively stable installation of the pipe body 100 on the water nozzle 300 and prevent it from easily detaching and falling. When pulling out, the user can directly hold the outer surface of the pipe body 100 and directly pull out the fitting pipe head 13 to achieve convenient installation and disassembly.

[0075] Such as Figures 2 to 5 The water bottle shown in the figure includes a bottle body 400 and a bottle cap 500 detachably connected to the bottle body 400. The bottle body 400 is provided with a water storage cavity 41 for storing water. An inlet 51 communicating with the outside is opened on the side of the bottle cap 500 away from the bottle body 400. The inlet 51 communicates with the water storage cavity 41. The inlet 51 is detachably connected to the water nozzle. The pipe body 100 communicates with the water storage cavity 41 of the bottle body 400 through the anti-scalding component 200.

[0076] Optionally, in some embodiments, the bottle body 400 can be made of materials such as glass, plastic, silica gel, stainless steel, etc. that are heat-resistant and easy to clean. Preferably, the bottle body 400 is made of food-safe silica gel material. The silica gel water bottle is relatively soft, comfortable to hold, and not easily broken, which is suitable for users to grip. Silica gel also has the property of being heat-resistant and can withstand temperatures up to 200°C, making it suitable for hot water disinfection and use during bathing. The surface of silica gel is smooth, not easily leaving water residues or odors, and is relatively easy to clean. It can be placed in a water bottle cleaning device for cleaning. Compared with glass and some plastics, silica gel water bottles are easy to mold, can be designed and produced in a variety of styles, and are lighter in weight, making them convenient to carry and suitable for outdoor use.

[0077] Optionally, in some embodiments, the bottle cap 500 can be made of elastic soft materials such as plastic and silica gel. Preferably, the bottle cap 500 is made of food-safe silica gel material. Silica gel has good elasticity and flexibility, which can help the bottle cap 500 effectively seal the bottle body 400, prevent water leakage, and keep the water fresh. Silica gel can withstand high temperatures up to 200°C, and the bottle cap 500 can be disinfected at high temperatures together with the bottle body 400 without worrying about deformation or releasing harmful substances. The silica gel material is not easily adhered to stains and is relatively easy to clean, and can be cleaned together when cleaning the bottle body 400, saving time and effort.

[0078] Specifically, in some embodiments, to further combine the water nozzle with the water bottle, the water bottle includes a bottle body 400 for storing water and a bottle cap 500 for installing the water nozzle 300. The bottle body 400 is provided with a water storage cavity 41 for storing water. The bottle body 400 can adopt either an integrally formed thin-walled structure or a hollow vacuum insulation structure. The water storage cavity 41 has a water storage port communicating with the outside on the bottle body 400. The bottle cap 500 is installed on the water storage port of the bottle body 400 by means of screwing through a threaded connection. The water nozzle 300 is provided with a nozzle cap connection portion 37 at the position where it contacts the bottle cap 500. The nozzle cap connection portion 37 is arranged in a ring around the center of the water nozzle 300 on the side away from the water suction port 34 and is recessed toward the ring center. During installation, by installing the nozzle cap connection portion 37 on the water inlet 51 of the bottle cap 500, the installation position of the water nozzle 300 can be determined. More specifically, as Figure 5As shown, on one side of the mouthpiece cover connecting portion 37 close to the water suction port 34, there is a first connecting flange 371, and on the side of the mouthpiece cover connecting portion 37 away from the water suction port 34, there is a second connecting flange 372. The outer diameter of the first connecting flange 371 is smaller than that of the second connecting flange 372, and the axial thickness of the first connecting flange 371 is smaller than the axial thickness of the second connecting flange 372. During installation, the mouthpiece cover connecting portion 37 is installed at the water inlet 51 of the bottle cap 500 such that the second connecting flange 372 is located between the bottle cap 500 and the bottle body 400. By using a screwing method of threaded connection, the second connecting flange 372 is pressed against the bottle body 400 through the bottle cap 500 to achieve a stable installation position of the water nozzle 300, realizing a detachable connection between the water bottle and the water nozzle 300.

[0079] As Figures 1 to 10 shown, the specific implementation manner of Embodiment 1 of the present utility model is as follows:

[0080] In this embodiment, the buckle portion 27 is located on the second installation plane 222, the clamping portion 28 is located on the first installation plane 212, and the elastic soft rubber layer 232 wraps the deformable metal 231 to form a spherical deformable member 23. The first installation housing 21 and the pipe body 100 are integrally formed, and the pipe channel 11 communicates with the first channel 211.

[0081] When assembling the anti-scalding component 200, the first installation housing 21 and the second installation housing 22 enclose to form a housing inner cavity 24. The deformable member 23 is placed in the housing inner cavity 24. The distance between the deformable member 23 and the first channel 211 is restricted by the first limiting member 25, and the distance between the deformable member 23 and the second channel 221 is restricted by the second limiting member 26. The buckle portion 27 extends into the clamping portion 28 such that the first installation plane 212 and the second installation plane 222 are closely attached, completing the mating connection between the first installation housing 21 and the second installation housing 22, and completing the assembly of the anti-scalding component 200.

[0082] The suction tube extends the end where the anti-scalding component 200 is located into the water bottle and contacts the liquid. When the user sucks the liquid through the suction tube from the end where the mating tube head 13 is located, the liquid enters the inner cavity 24 of the housing from the second channel 221 and successively flows through the first channel 211 and the tube channel 11 into the user's mouth to complete eating. When overheated liquid enters the inner cavity 24 of the housing from the second channel 221, the overheated liquid contacts the deformable member 23 and transfers the heat to the deformable metal 231 through the elastic soft rubber layer 232. The deformable metal 231 is heated and undergoes a phase change due to overheating. In the overheated state, the deformable metal 231 transforms the helical coiled structure into an unfolded form. During the process of unfolding the coiled structure, the deformable metal 231 continuously presses against the elastic soft rubber layer 232, causing the elastic soft rubber layer 232 to expand and stretch elastically until the elastic soft rubber layer 232 presses against the inner cavity 24 of the housing and fully blocks the flow cross-section of the inner cavity 24 of the housing. The liquid cannot flow through the space sealed by the elastic soft rubber layer 232. When undergoing overheating expansion and deformation, the deformable member 23 can use the pressing contact surface generated by the expansion to seal the contact gap between the first mounting housing 21 and the second mounting housing 22 at the same time, preventing the overheated liquid outside the anti-scalding component 200 from entering the tube channel 11 through the contact gap between the first mounting housing 21 and the second mounting housing 22 and scalding the user's mouth, achieving the effect of preventing overheated liquid from flowing towards the user's mouth, promptly blocking the flow of liquid with too high a temperature, without borrowing external tools and skin feeling temperature measurement, with a rapid overheat feedback response. The position of the deformable member 23 is restricted by the first limiting member 25 and the second limiting member 26, preventing the deformable member 23 from being blocked by the liquid flow at normal temperature. The overall structure is simple, the production and installation are convenient, and the manufacturing cost is reduced.

[0083] The specific implementation manner of Embodiment 2 of the present utility model is as follows:

[0084] Different from Embodiment 1, in this embodiment, the second mounting housing 22 and the tube body 100 are integrally formed, and the tube channel 11 communicates with the second channel 221.

[0085] The suction tube extends the end where the anti-scalding component 200 is located into the water bottle and contacts the liquid. When the user sucks the liquid through the suction tube from the end where the mating tube head 13 is located, the liquid enters the inner cavity 24 of the housing from the first channel 211 and successively flows through the second channel 221 and the tube channel 11 into the user's mouth to complete eating.

[0086] As Figure 11 and Figure 12 shown, the specific implementation manner of Embodiment 3 of the present utility model is as follows:

[0087] Different from Embodiment 1 and Embodiment 2, the channel mounting structure 29 is located in the first mounting housing 21. The first mounting housing 21 and the pipe body 100 are detachably connected through the cooperation of the channel engaging portion 291 and the pipe engaging portion 12. One end of the pipe body 100 close to the anti-scalding component 200 extends into the channel mounting structure 29, so that the protruding pipe engaging portion 12 is engaged and connected with the recessed channel engaging portion 291. Utilizing the characteristics of the relatively soft silicone material, an elastic clamping connection form is achieved. The design of the semi-circular protrusion and recess can facilitate insertion and extraction, improving the convenience of product installation and disassembly. The elasticity of the silicone material enables the protruding pipe engaging portion 12 to fully press against the surface of the recessed channel engaging portion 291, achieving a certain degree of elastic sealing effect, so that the water liquid cannot enter the pipe channel 11 through the channel mounting structure 29 outside the anti-scalding component 200, further avoiding scalding the user's oral cavity.

[0088] The specific implementation manner of Embodiment 4 of the present utility model is as follows:

[0089] Different from Embodiment 1, Embodiment 2, and Embodiment 3, the channel mounting structure 29 is located in the second mounting housing 22. The second mounting housing 22 and the pipe body 100 are detachably connected through the cooperation of the channel engaging portion 291 and the pipe engaging portion 12.

[0090] As Figures 1 to 10 shown, the specific implementation manner of Embodiment 5 of the present utility model is as follows:

[0091] Based on any one of Embodiments 1 - 4, the suction pipe is installed on the water nozzle.

[0092] During installation, the user inserts the mating pipe head 13 into the clamping channel of the clamping portion 32. The rounded surface structure 132 on the side of the mating pipe head 13 away from the anti-scalding component 200 pushes away the second protruding portion 36. After the first protruding portion 35 comes into contact with and is engaged with the first recessed portion 131, it stops inserting. The rounded surface structure 132 on the side of the mating pipe head 13 close to the anti-scalding component 200 comes into contact with the second protruding portion 36, so as to strengthen the relatively stable installation of the pipe body 100 on the water nozzle 300. The friction between the soft silicone and the soft silicone restricts the position of the mating pipe head 13 in the clamping portion 32 and does not easily fall off. After one end of the pipe body 100 facing the anti-scalding component 200 extends into the water bottle and contacts the water liquid, the water nozzle 300 is then installed on the water bottle. The user can suck the water liquid by contacting the sucking portion 31. The water liquid enters the inner cavity 24 of the housing through the second channel 221 and flows through the first channel 211, the pipe channel 11, the sucking inner cavity 33, and the water absorption port 34 in sequence to enter the user's oral cavity to complete eating.

[0093] During removal, the user can directly hold the outer surface of the pipe body 100 and directly pull out the mating pipe head 13, achieving convenient installation and disassembly.

[0094] As Figures 1 to 10 shown, the specific implementation manner of Embodiment 6 of the present utility model is as follows:

[0095] Based on Embodiment 5, the water nozzle is installed on the water bottle.

[0096] During installation, the nozzle cover connecting portion 37 of the water nozzle 300 is installed at the water inlet 51 of the bottle cap 500 such that the second connecting flange 372 is located between the bottle cap 500 and the bottle body 400. The end of the straw where the anti-scalding component 200 is located extends into the water bottle and contacts the water liquid. The bottle cap 500 is installed on the water storage port of the bottle body 400 by screwing in a threaded connection manner. The second connecting flange 372 is pressed against the bottle body 400 by the bottle cap 500 in a threaded connection and screwing manner to achieve a stable installation position of the water nozzle 300, realizing a detachable connection between the water bottle and the water nozzle 300. The user can suck the water liquid by contacting the sucking portion 31.

[0097] The above only uses embodiments to further illustrate the technical content of the present utility model to make it easier for readers to understand, but it does not mean that the implementation manners of the present utility model are limited to this. Any technical extension or re-creation made according to the present utility model is protected by the present utility model. The protection scope of the present utility model is subject to the claims.
