A pipe structure, a mounting structure, and a product

Abstract

This application discloses a pipe structure, installation structure, and product. The pipe structure includes a pipe body; one end of the pipe body is a negative pressure receiving end, and the other end is a suction end. The pipe body includes a valve section and a deformable section. The deformable section has a first flow channel connecting to the negative pressure receiving end and a second flow channel connecting to the suction end. The valve section is used to connect or close the first flow channel and the second flow channel. The deformable section is configured such that when the pressure difference between the external pressure on the first flow channel and the internal air pressure of the first flow channel reaches a preset threshold, the deformable section undergoes inward deformation. The deformable section is used to drive the valve section to connect the first flow channel and the second flow channel through inward deformation. When a negative pressure source is connected through the negative pressure receiving end, the deformable section deforms due to the decrease in air pressure inside the first flow channel and is subjected to external air pressure, thereby driving the valve section to connect the first and second flow channels. By utilizing the external air pressure to assist in opening the valve section, the experience of liquid or air suction in the pipe structure can be improved.

Description

Technical Field

[0001] This application relates to the field of pipeline design technology, and in particular to a pipeline structure, installation structure and product. Background Technology

[0002] In most products on the market that achieve liquid or air suction through negative pressure, the pipe structure usually cannot simultaneously achieve both backflow prevention and ease of use.

[0003] Taking straw cups as an example, when the lid is opened or the cup is shaken, the straw is prone to splashing liquid. If the liquid in the cup is hot, it may splash out and burn the person. Therefore, straw cups are usually equipped with a straw with anti-splash function.

[0004] In some related technologies, the anti-splash function of straws is generally achieved by setting a vent plug on the cup lid. However, because the vent plug has a small channel and a slow venting speed, the high-pressure gas inside the cup will still quickly overflow from the straw mouth and splash out the liquid, resulting in poor anti-splash effect.

[0005] In another related technology, the anti-splash function of the straw is achieved by setting a V-shaped one-way valve on the straw mouthpiece. However, it requires biting and sucking when used. When used by children or the elderly with weak biting ability, it is difficult to open the valve effectively, resulting in difficulty in sucking water. Utility Model Content

[0006] This application proposes a pipeline structure to effectively solve the technical problem in related technologies where products that achieve liquid or air suction through negative pressure cannot simultaneously achieve both backflow prevention and ease of use.

[0007] A first aspect of this application provides a pipe structure, including: a pipe body;

[0008] One end of the pipe body serves as a negative pressure receiving end, and the other end serves as a suction end;

[0009] The pipe body includes a valve section and a deformable section. The deformable section forms a first flow channel connecting the negative pressure receiving end and a second flow channel connecting the suction end. The valve section is disposed on the deformable section and is used to connect or cut off the first flow channel and the second flow channel.

[0010] The deformation part is configured such that when the pressure difference between the external pressure of the first flow channel and the internal air pressure of the first flow channel reaches a preset threshold, the deformation part undergoes inward deformation.

[0011] The deformable part is used to drive the valve part through inward deformation to connect the first flow channel and the second flow channel.

[0012] Furthermore, the valve section includes a first valve disc and a second valve disc that can be opened and closed. When the deformable section deforms inward, it causes the first valve disc and the second valve disc to move away from each other, so that the first flow channel and the second flow channel are connected.

[0013] Furthermore, the outer wall of the deformable part has an elliptical cross-sectional shape, and the relative movement direction of the first valve disc and the second valve disc is parallel to the extension direction of the long axis of the outer wall of the deformable part. When the two ends of the short axis of the outer wall of the deformable part deform inward, the first valve disc and the second valve disc move away from each other.

[0014] Furthermore, the inner wall of the deformable part has an elliptical cross-sectional shape, and the wall thickness at both ends of the major axis of the outer wall of the deformable part is less than or greater than the wall thickness at both ends of the minor axis of the outer wall of the deformable part.

[0015] Alternatively, the inner wall of the deformable part has a circular cross-sectional shape, and the wall thickness at both ends of the major axis of the outer wall of the deformable part is greater than the wall thickness at both ends of the minor axis of the outer wall of the deformable part.

[0016] Or, the inner wall cross-section of the deformable part is elliptical, and the cross-sectional wall thickness of the deformable part is uniform.

[0017] Furthermore, the outer wall of the deformable part has an elliptical cross-sectional shape, and the relative movement direction of the first valve disc and the second valve disc is parallel to the extension direction of the minor axis of the outer wall of the deformable part. When the two ends of the minor axis of the outer wall of the deformable part deform inward, the first valve disc and the second valve disc move away from each other.

[0018] The inner wall of the deformable part has an elliptical cross-sectional shape, and the wall thickness at both ends of the major axis of the outer wall of the deformable part is greater than or less than the wall thickness at both ends of the minor axis of the outer wall of the deformable part, or the inner wall of the deformable part has an elliptical cross-sectional shape, and the cross-sectional wall thickness of the deformable part is equal.

[0019] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects: On the basis of achieving the backflow prevention function through the valve part, when the negative pressure source is connected through the negative pressure receiving end, the deformable part will deform due to the reduction of the air pressure inside the first flow channel and will be driven by the external air pressure, thereby connecting the first flow channel and the second flow channel. By using the external air pressure to assist in opening the valve part, the experience of liquid or air suction in the pipeline structure can be improved.

[0020] A second aspect of this application provides an installation structure, including a pipe structure as described in the first aspect of this application.

[0021] Furthermore, the installation structure includes a housing, and the pipe body is disposed on the housing. The housing and the pipe structure are either an integral structure or a separate structure.

[0022] Furthermore, an installation cavity is formed on the housing, the pipe body passes through the installation cavity and is disposed on the housing, and at least a portion of the deformable part is located in the installation cavity, so that when the air pressure value in the first flow channel is less than the air pressure value in the installation cavity, the deformable part can be deformed inward by air pressure.

[0023] Furthermore, the pipe body includes a first protrusion, and a first groove is formed on one end of the mounting cavity near the negative pressure receiving end. When the pipe body is disposed on the housing, the first protrusion is disposed in the first groove so that the housing can limit the pipe body.

[0024] And / or, the pipe body includes a second boss portion, and a second groove is formed on the other end of the mounting cavity near the suction end. When the pipe body is disposed on the housing, the second boss portion is disposed in the second groove so that an end face seal is formed between the housing and the pipe body.

[0025] And / or, the mounting structure is used to be mounted on the container, and the shell is provided with a return air hole, which is used to open when the air pressure value inside the container drops to a preset value, so as to make the cavity of the container communicate with the outside.

[0026] And / or, the mounting cavity is in communication with the outside, and there is a gap between the outer wall surface of the deformable part and the cavity wall in the housing that forms the mounting cavity.

[0027] A third aspect of this application provides a product including: a pipe structure as described in the first aspect of this application;

[0028] Or an installation structure as described in the second aspect of this application.

[0029] It is easy to understand that the installation structure in the second aspect embodiment of this application and the product in the third aspect embodiment of this application both have the same technical effects as the pipeline structure in the first aspect embodiment, and therefore will not be described again.

[0030] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0047] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0048] See Figures 1 to 10 As shown, an embodiment of the first aspect of this application discloses a pipe structure, including: a pipe body 200;

[0049] One end of the pipe body 200 serves as a negative pressure receiving end 201, and the other end serves as a suction end 202. The pipe body 200 includes a valve section 210 and a deformable section 220. The deformable section 220 forms a first flow channel 2201 connecting the negative pressure receiving end 201 and a second flow channel 2202 connecting the suction end 202. The valve section 210 is disposed on the deformable section 220 and is used to connect or disconnect the first flow channel 2201 and the second flow channel 2202. The deformable section 220 is configured such that when the pressure difference between the external pressure on the first flow channel 2201 and the internal air pressure of the first flow channel 2201 reaches a preset threshold, the deformable section 220 undergoes inward deformation. The deformable section 220 is used to drive the valve section 210 to connect the first flow channel 2201 and the second flow channel 2202 through inward deformation.

[0050] In the embodiments of this application, based on the anti-backflow function achieved by the valve part 210, when the negative pressure source is connected through the negative pressure receiving end 201, the deformation part 220 will deform due to the decrease in air pressure inside the first flow channel 2201 and will be driven by the external air pressure, thereby connecting the first flow channel 2201 and the second flow channel 2202. By using the external air pressure to assist in opening the valve part 210, the experience of liquid or air suction in the pipeline structure can be improved.

[0051] Understandably, in some embodiments, when the negative pressure receiving end 201 of the pipe body 200 is connected to a negative pressure source during use, the valve part 210 opens based on the inward deformation of the deformable part 220. Liquid or gas enters the pipe structure through the suction end 202 and is output from the negative pressure receiving end 201 via the conveying of the pipe body 200. Based on this, a flow channel is formed within the deformable part 220, and the valve part 210 is disposed within the flow channel and divided into a first flow channel 2201 and a second flow channel 2202. The first flow channel 2201 is used to connect to the negative pressure receiving end 201. Therefore, when the negative pressure source is input to the pipe structure through the negative pressure receiving end 201, the air pressure inside the first flow channel 2201 decreases. When the pressure difference between the external pressure and the internal air pressure of the first flow channel 2201 reaches a preset threshold, the deformable part 220 deforms inward based on the pressure difference reaching the preset threshold, thereby opening the valve part 210 to facilitate the outflow of liquid or gas.

[0052] In some embodiments, the provision or input of the negative pressure source may be implemented in different ways depending on the specific application scenario. This includes, but is not limited to, providing the negative pressure source directly through the user's inhalation, or through the connection of a negative pressure pump, or through the provision of the negative pressure source through a pipeline. No further limitations are made here, and adjustments can be made according to the actual application.

[0053] In some embodiments, the preset threshold also needs to be set according to different specific application scenarios. For example, when the pressure difference between the external pressure of the first flow channel 2201 and the internal air pressure of the first flow channel 2201 is greater than zero or a specific value, the deformable part 220 will deform inward and drive the valve part 210 to open.

[0054] In some embodiments, the deformable part 220 is made of a flexible material. Furthermore, the cross-sectional shape of the deformable part 220 can be designed into various shapes according to actual usage requirements, such as circular, elliptical, square, or irregular shapes. Based on the fact that the deformable part 220 can drive the valve part 210 to move through deformation and can effectively solve the technical problem that it is difficult to simultaneously achieve the two functions of anti-backflow effect and ease of use in related technologies, the specific structural form can be adaptively selected, which will not be further described here.

[0055] In some embodiments, the pipe body 200 and the deformable portion 220 are an integral structure, with the deformable portion 220 serving as a part of the pipe body 200. In other embodiments, the pipe body 200 comprises multiple pipe segments, each segment connected to form the pipe body 200, with the deformable portion 220 disposed on one or more consecutive pipe segments. This also achieves the effects described in the embodiments of this application, and will not be further elaborated here.

[0056] It should be noted that the pipe structure of this application embodiment can be used in products that achieve liquid or air suction functions through negative pressure, such as sippy cups, breast pumps, nebulizers, and vacuum cleaners. Furthermore, the pipe structure of this application embodiment can also be applied to automated equipment, so that products equipped with the pipe structure of this application embodiment can, as far as possible, balance the functions of backflow prevention and ease of use. It should be understood that, based on the disclosure of the embodiments of this application, any adaptive and simple improvements made by those skilled in the art without creative effort, enabling the resulting pipe structure to be used in other types of products or other technical fields, should also be considered within the scope of protection of this application.

[0057] The following will combine Figures 1 to 10 The pipeline structure disclosed in the embodiments of this application will be explained and described in detail.

[0058] It is understood that the following explanation and description mainly uses a straw cup as an example, and the user provides a negative pressure source by sucking. However, this specific explanation and description should not be construed as a limitation on the embodiments of this application.

[0059] In some embodiments of this application, reference is made to Figures 1 to 10 The valve section 210 includes a first valve flap 211 and a second valve flap 212 that can be opened and closed. When the deformable section 220 deforms inward, it causes the first valve flap 211 and the second valve flap 212 to move away from each other, so that the first flow channel 2201 and the second flow channel 2202 are connected. It can be understood that the valve section 210 is used to control the water flow and prevent water leakage, thereby adapting to the user's slurping habits. Based on this, by setting the valve section 210 to include the first valve flap 211 and the second valve flap 212, specifically, when the first valve flap 211 and the second valve flap 212 move away from each other, a thin, elongated gap similar to a "one" is formed. Therefore, the valve section 210 can also be understood as a straight valve. Under normal circumstances, the gap is in a naturally closed state, which can effectively prevent the liquid in the cup from leaking out. When in use, the negative pressure and the deformation of the deformable section 220 will cause the gap to open slightly, and the liquid will flow out through the gap to meet the drinking needs. After slurping stops, the gap will automatically close, forming a seal again to prevent water leakage when the cup is inverted or shaken. Therefore, the first valve disc 211 and the second valve disc 212, which can be opened and closed, can not only adjust the water flow by controlling the opening and closing of the gap to reduce the risk of choking, but also take into account the leak prevention function.

[0060] In some embodiments, the first valve flap 211 and the second valve flap 212 are made of soft silicone. In other embodiments, the first valve flap 211 and the second valve flap 212 are made of other deformable materials, which will not be described further here.

[0061] In other embodiments, the valve section 210 may also be configured with common valve structures such as duckbill valves, silicone diaphragm valves, or cross valves, depending on different usage requirements, which will not be further described here.

[0062] It should be understood that, in order to make it easier for the valve part 210 to open through deformation of the deformable part 220 and to improve the quality of opening to the correct position, in some embodiments of this application, reference is made to... Figure 4 and Figure 5 The outer wall surface 221 of the deformable part 220 has an elliptical cross-sectional shape. The relative movement direction of the first valve disc 211 and the second valve disc 212 is parallel to the extension direction of the long axis of the outer wall surface 221 of the deformable part 220. When the two ends of the short axis of the outer wall surface 221 of the deformable part 220 deform inward, the first valve disc 211 and the second valve disc 212 move away from each other.

[0063] It is understandable that by specifically designing the structure of the deformable part 220 and determining the relative movement direction of the first valve disc 211 and the second valve disc 212, the valve part 210 can be opened more easily, with better positioning quality, and the opening accuracy of the valve part 210 can be determined more precisely through deformation.

[0064] It should be understood that, based on the elliptical cross-sectional shape of the outer wall surface 221 of the deformable part 220, the inner wall surface 222 of the deformable part 220 can be further designed to meet different usage requirements. On this basis, since the cross-sectional shape of the inner wall surface 222 of the deformable part 220 is the same as that of the valve part 210, the cross-sectional shapes of the inner wall surface 222 of the deformable part 220 and the valve part 210 can be designed to match each other to improve the opening and closing rate of the valve part 210 and ensure that the deformable part 220 can take into account both the functions of preventing backflow and conveying liquid.

[0065] Exemplary, in some embodiments, reference is made to Figure 4 The inner wall surface 222 of the deformable part 220 has an elliptical cross-sectional shape, and the wall thickness at both ends of the major axis of the outer wall surface 221 of the deformable part 220 is less than the wall thickness at both ends of the minor axis of the outer wall surface 221 of the deformable part 220.

[0066] Exemplary, in some embodiments, reference is made to Figure 5 The inner wall surface 222 of the deformable part 220 has an elliptical cross-sectional shape, and the wall thickness at both ends of the major axis of the outer wall surface 221 of the deformable part 220 is greater than the wall thickness at both ends of the minor axis of the outer wall surface 221 of the deformable part 220.

[0067] Exemplary, in some embodiments, reference is made to Figure 6 The inner wall surface 222 of the deformed part 220 has an elliptical cross-sectional shape, and the cross-sectional wall thickness of the deformed part 220 is uniform.

[0068] Exemplary, in some embodiments, reference is made to Figure 7 The inner wall surface 222 of the deformable part 220 has a circular cross-sectional shape. The wall thickness at both ends of the long axis of the outer wall surface 221 of the deformable part 220 is greater than the wall thickness at both ends of the short axis of the outer wall surface 221 of the deformable part 220. This can also meet the opening and closing rate requirements of the valve part 210, ensuring that the deformable part 220 can take into account both the functions of preventing backflow and conveying liquid.

[0069] It should be understood that, in order to make it easier for the valve part 210 to open through deformation of the deformable part 220 and to improve the quality of opening to the correct position, in some embodiments of this application, reference is made to... Figures 8 to 10 The outer wall surface 221 of the deformable part 220 has an elliptical cross-sectional shape. The relative movement direction of the first valve flap 211 and the second valve flap 212 is parallel to the extension direction of the short axis of the outer wall surface 221 of the deformable part 220. When the two ends of the short axis of the outer wall surface 221 of the deformable part 220 deform inward, the first valve flap 211 and the second valve flap 212 move away from each other.

[0070] Based on this, exemplarily, in some embodiments, reference is made to Figure 8 The inner wall surface 222 of the deformable part 220 has an elliptical cross-sectional shape, and the wall thickness at both ends of the major axis of the outer wall surface 221 of the deformable part 220 is greater than the wall thickness at both ends of the minor axis of the outer wall surface 221 of the deformable part 220.

[0071] Exemplary, in some embodiments, reference is made to Figure 9 The inner wall surface 222 of the deformable part 220 has an elliptical cross-sectional shape, and the wall thickness at both ends of the major axis of the outer wall surface 221 of the deformable part 220 is less than the wall thickness at both ends of the minor axis of the outer wall surface 221 of the deformable part 220.

[0072] Exemplary, in some embodiments, reference is made to Figure 10 The inner wall surface 222 of the deformed part 220 has an elliptical cross-sectional shape, and the cross-sectional wall thickness of the deformed part 220 is uniform.

[0073] The above settings also improve the opening and closing accuracy of the valve section 210, ensuring that the deformable section 220 can perform both anti-backflow and liquid conveying functions.

[0074] The second aspect of this application discloses an installation structure, which can be an installation structure for water cup products such as straw cups, sippy cups, or insulated cups, or an installation structure for products that achieve liquid or air suction functions through negative pressure, such as the installation structure for products that work through negative pressure, such as straw cups, breast pumps, nebulizers, and vacuum cleaners, or an installation structure for automated equipment products. The installation structure includes: the pipe structure of the first aspect of this application.

[0075] In some embodiments, for example, the pipe structure is disposed on the mounting structure, which is disposed on the container 300. The mounting structure includes a housing 100. One end of the pipe body 200 serves as a negative pressure receiving end 201, and the other end serves as a suction end 202 for extending into the container 300. A mounting cavity 110 is formed on the housing 100, and the pipe body 200 passes through the mounting cavity 110 and is disposed on the housing 100. The pipe body 200 includes a valve portion 210 and a deformable portion 220. The deformable portion 220 forms a flow channel that communicates with the negative pressure receiving end 201 and the suction end 202 respectively. The valve portion 210 is disposed on the deformable portion 220 and is used to open or close the flow channel. At least a portion of the deformable portion 220 is located inside the mounting cavity 110, so that when the air pressure value in the flow channel is less than the air pressure value in the mounting cavity 110, the deformable portion 220 can be deformed inward by air pressure. The deformable portion 220 is used to drive the valve portion 210 to open the flow channel through inward deformation.

[0076] Based on this, while the anti-splash function is achieved through the valve part 210, when the user draws water through the negative pressure receiving end 201, the deformation part 220 will deform due to the reduced air pressure inside the pipe body 200 and the air pressure of the installation cavity 110, causing the valve part 210 to open. Then, the suction end 202 can smoothly draw water from the container 300. The external air pressure helps to open the valve part 210, making it convenient to use and improving the water suction experience.

[0077] Furthermore, the pipe body 200 of this embodiment includes a valve section 210 and a deformable section 220. The deformable section 220 forms a flow channel that communicates with the negative pressure receiving end 201 and the suction end 202 respectively without affecting the delivery of liquid. The valve section 210 is used to open or close the flow channel, so that when it is open, the liquid can be smoothly delivered for the user to drink, and when it is closed, it can prevent the liquid from splashing and leaking out. Furthermore, by providing at least a portion of the deformable section 220 in the mounting cavity 110, and limiting the air pressure value in the mounting cavity 110 to a preset range, when the air pressure value in the deformable section 220 decreases due to the user's intake of water, the air pressure in the mounting cavity 110 can act synchronously on the deformable section 220, causing the deformable section 220 to deform inward. The deformation of the deformable section 220 then causes the valve section 210 to open, thereby allowing the user to conveniently and effortlessly drink liquid through the pipe body 200, improving the ease of use.

[0078] In some embodiments, an adjustment component may be provided on the housing 100 to limit the air pressure value inside the mounting cavity 110 to a preset range, thereby ensuring that the deformable part 220 can deform smoothly and properly inward under the action of air pressure. In other embodiments, the mounting cavity 110 may be directly connected to atmospheric pressure. When the user draws water through the negative pressure receiving end 201, the deformable part 220 can also deform under the action of air pressure in the mounting cavity 110 due to the decrease in air pressure inside the pipe body 200. The specific setting method can be selected according to the actual situation so that the pipe structure of the present application embodiment meets the needs of different usage scenarios.

[0079] In some embodiments, the pipe body 200 is disposed on the housing 100, and the housing 100 and the pipe structure are either an integral structure or a separate structure. It is understood that the housing 100 and the pipe structure can be an integral structure or a separate structure, and can be assembled by common connection methods to achieve the corresponding functions of the embodiments of this application.

[0080] To improve the positioning effect of the pipe body 200 on the housing 100 and prevent the pipe body 200 from sinking into the container 300 under external force, in some embodiments of this application, such as Figures 1 to 3 The pipe body 200 includes a first boss portion 230. A first groove 111 is formed on one end of the mounting cavity 110 near the negative pressure receiving end 201. When the pipe body 200 is mounted on the housing 100, the first boss portion 230 is disposed in the first groove 111 so that the housing 100 can limit the pipe body 200.

[0081] It is understandable that the pipe body 200 is reliably positioned on the housing 100 by the first boss portion 230 being disposed in the first groove 111. This not only ensures the installation accuracy in all directions by utilizing the limiting effect of the first groove 111, but also prevents the pipe body 200 from sinking into the container 300 when subjected to external forces by utilizing the abutment and limiting effect of the first groove 111 on the first boss portion 230.

[0082] To improve the sealing effect between the shell 100 and the cavity of the container 300, in some embodiments of this application, such as... Figures 1 to 3 The pipe body 200 includes a second boss portion 240. A second groove 112 is formed on the other end of the mounting cavity 110 near the suction end 202. When the pipe body 200 is mounted on the housing 100, the second boss portion 240 is disposed in the second groove 112 so that an end face seal is formed between the housing 100 and the pipe body 200.

[0083] It is understandable that the shell 100 is mounted on the container 300, and the second protrusion 240 and the second groove 112 are located in the cavity inside the container 300. The second protrusion 240 is mounted in the second groove 112 and the end face is sealed, which prevents the mounting cavity 110 from communicating with the cavity of the container 300, ensuring that the liquid inside the container 300 is reliably sealed. The replenishment of the air pressure inside the container 300 can keep the air pressure inside the container 300 stable through common air return structures such as the air return hole 120.

[0084] To further ensure the convenience and rationality of using container 300, and to avoid affecting the bottle body of container 300 due to air pressure, in some embodiments of this application, such as... Figures 1 to 3 The housing 100 is provided with a return air hole 120, which is used to open when the air pressure in the container 300 drops to a preset value, so that the cavity of the container 300 can communicate with the outside.

[0085] It is understandable that after the user draws water through the pipe body 200, the air pressure inside the container 300 will decrease due to the reduction in water volume, provided that there is a reliable seal between the container 300 and the shell 100. However, the air return hole 120 allows the cavity of the container 300 to be restored to the initial air pressure value in a timely manner, thus preventing external air pressure from affecting the bottle body of the container 300 and impacting the user experience.

[0086] In some embodiments, the vent 120 is provided with a valve configured to open and close in response to changes in the air pressure within the container 300, thereby achieving the desired effect.

[0087] In other embodiments, other commonly used structures that can be provided on the vent 120 to restore the internal air pressure of the container 300 may be provided, which will not be described in further detail here.

[0088] In some embodiments of this application, such as Figures 1 to 3 The mounting cavity 110 is open to the outside, and there is a gap between the outer wall 221 of the deformable part 220 and the cavity wall in the housing 100 that forms the mounting cavity 110. It is understood that by reserving sufficient space between the deformable part 220 and the cavity wall of the mounting cavity 110, a sufficient amount of gas is provided within the mounting cavity 110 to provide a stable gas pressure and ensure that the provided gas pressure meets usage requirements. This allows for timely application of gas pressure to the deformable part 220 when the gas pressure value within the deformable part decreases.

[0089] The pipeline structure of this application embodiment is described in detail below with a specific example. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0090] See Figures 1 to 10As shown, the pipe structure of this embodiment includes a pipe body 200, a valve part 210, and a deformable part 220. Normally, the valve part 210 is closed, thereby preventing the liquid in the container 300 from flowing out from the negative pressure receiving end 201 at the upper end of the pipe body 200, and also preventing the hot water in the container 300 from spraying out from the negative pressure receiving end 201 when the container 300 is vibrated or shaken.

[0091] When using the water suction function, the suction process includes: Water is drawn from the negative pressure receiving end 201, reducing the air pressure in the cavity of the flow channel within the pipe body 200, thus connecting the installation cavity 110 to the external environment. The pressure is typically 0.1 MPa. During suction, the air pressure in the flow channel cavity is lower than the pressure in the installation cavity 110 (0.1 MPa), causing the deformable part 220 to deform inward, opening the slot in the valve part 210, allowing water to be drawn out. This allows liquid in the container 300 to be drawn in from the suction end 202 at the lower end of the pipe body 200, and then drawn out from the negative pressure receiving end 201 through the valve part 210. Simultaneously, the shell 100 is provided with a return air hole 120 that communicates with the outside environment to balance the air pressure inside the cup.

[0092] Furthermore, in a first embodiment of the pipe body 200, refer to Figure 4 The cross-section of the deformable part 220 is elliptical. The wall thickness is thin when perpendicular to the long side of the ellipse and thick when perpendicular to the short side of the ellipse. When water is absorbed, the thick wall deforms inward, the slot of the valve part 210 opens, and water is drawn out from the negative pressure receiving end 201.

The wall thickness is perpendicular to the long side of the ellipse and the wall thickness is perpendicular to the short side of the ellipse. When water is absorbed, the thin wall deforms inward, the slot of the valve part 210 opens, and water is drawn out from the negative pressure receiving end 201.

[0094] A third embodiment of the pipe body 200 is described below. Figure 6 The cross-section of the deformable part 220 is elliptical, and the wall thickness of the cross-section of the deformable part 220 is uniform. When water is absorbed, the elliptical wall deforms inward as a whole, the slot of the valve part 210 opens, and water is drawn out from the negative pressure receiving end 201.

[0095] The fourth embodiment of the pipe body 200, see reference to Figure 7 The cross-section of the deformable part 220 is elliptical on the outside and circular on the inside. The wall thickness is perpendicular to the long side of the outer ellipse and thin on the short side. When water is absorbed, the thin wall deforms, the slot of the valve part 210 opens, and water is drawn out from the negative pressure receiving end 201.

[0096] The fifth embodiment of the pipe body 200, see reference. Figure 8The cross-section of the deformable part 220 is elliptical. The wall thickness is perpendicular to the long side of the ellipse and the wall thickness is perpendicular to the short side of the ellipse. When water is absorbed, the thin wall deforms inward, the slot of the valve part 210 opens, and water is drawn out from the negative pressure receiving end 201.

[0097] The sixth embodiment of the pipe body 200, see reference. Figure 9 The cross-section of the deformable part 220 is elliptical. The wall thickness is thin when perpendicular to the long side of the ellipse and thick when perpendicular to the short side of the ellipse. When water is absorbed, the thick wall deforms inward, the slot of the valve part 210 opens, and water is drawn out from the negative pressure receiving end 201.

[0098] The seventh embodiment of the pipe body 200, see reference. Figure 10 The cross-section of the deformable part 220 is elliptical, and the wall thickness of the cross-section of the deformable part 220 is uniform. When water is absorbed, the elliptical wall deforms inward as a whole, the slot of the valve part 210 opens, and water is drawn out from the negative pressure receiving end 201.
