Description

TECHNICAL FIELD

[0001] The present application relates to the field of household appliances, and in particular to a liquid heating container. BACKGROUND

[0002] The liquid heating container generally comprises a kettle body and a kettle cover buckled on the kettle body, the kettle cover is provided with an exhaust hole, and when the liquid heating container heats the liquid, the steam generated in the kettle body can be discharged outward from the exhaust hole to reduce the pressure in the kettle body.

[0003] A waterproof and breathable film is usually arranged in the kettle cover, the waterproof and breathable film has the characteristics of allowing steam to pass through and preventing water from passing through, and can prevent water leakage while discharging steam and relieving pressure. However, the waterproof and breathable film may be blocked and fail during use, resulting in excessive pressure in the kettle body due to the inability of the steam to be discharged, and a certain safety hazard exists. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a liquid heating container, which can solve the problem that the liquid heating container in the prior art cannot discharge steam when the waterproof and breathable film fails.

[0005] The present application provides a liquid heating container, which comprises a kettle body, an inner cover detachably connected with the kettle body, the inner cover being provided with an exhaust hole and an exhaust port, the exhaust hole being in communication with the outside world, a waterproof and breathable film fixed to the inner cover, steam in the kettle body being able to flow to the exhaust hole through the waterproof and breathable film, and a pressure relief member movably connected to the inner cover, the pressure relief member being used to open the exhaust port when the gas pressure in the kettle body is greater than a preset value, so that the steam in the kettle body can flow to the exhaust hole through the exhaust port, and the pressure relief member being further used to close the exhaust port when the gas pressure in the kettle body is less than or equal to the preset value, so as to cut off the communication between the exhaust port and the exhaust hole.

[0006] In the above scheme, when the liquid inside the kettle body is heated by the liquid heating container, the inner cover is connected to the kettle body, and the steam generated by the liquid heating can flow to the exhaust hole through the waterproof breathable membrane, and then flow to the outside through the exhaust hole, so as to realize the effect of pressure relief and exhaust, avoid the connection between the inner cover and the kettle body to be invalid due to the excessive pressure inside the kettle body, and prevent the liquid from splashing outwards when boiling, thereby avoiding scalding the user and avoiding water leakage of the liquid heating container. After heating, when the user needs to drink water, the inner cover can be detached from the kettle body, and then the water can be poured outwards. The detachable structure is more convenient for the user to clean the kettle body and the inner cover. When the gas pressure inside the kettle body is greater than the preset value, the pressure relief member can move upward under the action of the gas pressure to open the exhaust port. At this time, the exhaust port is in communication with the exhaust hole, and the steam inside the kettle body can flow to the exhaust hole through the exhaust port and then flow to the outside through the exhaust hole. When the waterproof breathable membrane is blocked and fails, the pressure relief member can open the exhaust port to play a role in exhaust and pressure relief, thereby reducing the internal pressure of the kettle body and improving the use safety of the liquid heating container. Of course, when the gas pressure inside the kettle body is too large although the waterproof breathable membrane is not failed, the pressure relief member can also open the exhaust port to assist the waterproof breathable membrane to play a role in exhaust and pressure relief. When the gas pressure inside the kettle body is less than or equal to the preset value, the gas pressure inside the kettle body is not enough to drive the pressure relief member to move upward, and the pressure relief member can close the exhaust port. At this time, the communication between the exhaust port and the exhaust hole is cut off to prevent the liquid inside the kettle body from flowing to the exhaust hole through the exhaust port. That is, the pressure relief member can play a role in sealing and preventing water leakage.

[0012] In the scheme, when the gas pressure in the kettle body is greater than the preset value, the pressure relief member can move upward relative to the exhaust port under the action of the gas pressure, so that the blocking portion moves away from the abutting portion, and the steam can flow from the gap between the blocking portion and the abutting portion to the exhaust hole, thereby opening the exhaust port. When the gas is discharged, the gas pressure in the kettle body is less than the preset value, and the pressure relief member can move downward relative to the exhaust port to reset, until the blocking portion abuts against the abutting portion to realize the sealing cooperation, thereby closing the exhaust port. In the process of the upward and downward movement of the pressure relief member relative to the exhaust port, the main body portion can be limited and matched with the inner wall of the exhaust port, so as to improve the stability of the pressure relief member.

[0013] In a possible design, the abutting portion is provided with a first guide inclined surface, and the blocking portion is provided with a second guide inclined surface matched with the first guide inclined surface.

[0014] In the scheme, in the process of the upward and downward movement of the pressure relief member relative to the exhaust port, the first guide inclined surface and the second guide inclined surface can be guided and matched to limit the movement of the pressure relief member in the radial direction, thereby improving the movement stability of the pressure relief member.

[0019] In a possible design, the inner cover further comprises a filter screen provided with filter holes, and the steam and liquid in the kettle body can flow to the exhaust port and the waterproof and breathable membrane through the filter holes.

[0020] In the above scheme, the filter screen can filter food residues and impurities. When the liquid heating container is heated, the filter screen can prevent the boiling water or steam from directly impacting the waterproof and breathable membrane, which is beneficial to improve the service life of the waterproof and breathable membrane.

In addition, the character " / " in this paper generally represents that the front and rear associated objects are in an "or" relationship.

[0080] It should be noted that the "up", "down", "left", "right" and the like described in the embodiments of the present application are described from the angle shown in the drawings, and should not be understood as a limitation of the embodiments of the present application. In addition, in the context, it should also be understood that when referring to an element connected to another element "on" or "under", it can be directly connected to another element "on" or "under" or indirectly connected to another element "on" or "under" through an intermediate element.

[0081] The embodiments of the present application provide a liquid heating container, as shown in the drawings, Figure 1 The liquid heating container includes a kettle body 10 and an inner cover 20. The kettle body 10 includes a fixedly connected outer shell 103 and a base 104, the outer shell 103 is provided with an inner container 105 for containing liquid and a heating disc assembly 101 mounted on the outer bottom wall of the inner container 105 for heating the liquid. The base 104 is provided with a circuit board assembly 102, which is electrically connected with the heating disc assembly 101, for controlling the heating temperature or heating time of the liquid heating container. The inner cover 20 is detachably connected with the kettle body 10, as shown in the drawings, Figure 2 The top of the inner cover 20 is provided with an exhaust hole 20a communicating with the outside, and a waterproof and breathable film 1 is fixedly installed in the inner cover 20, which has the properties of air permeability and waterproofness. When the liquid heating container heats the liquid, the inner cover 20 is connected with the kettle body 10, and the steam generated by the heating of the liquid can flow to the exhaust hole 20a through the waterproof and breathable film 1, and then flow to the outside through the exhaust hole 20a, so as to realize the effect of pressure relief and exhaust, avoid the connection between the inner cover 20 and the kettle body 10 to be invalid due to the excessive internal pressure of the kettle body 10, and prevent the liquid from splashing outwards when boiling, so as to avoid scalding the user and also avoid water leakage of the liquid heating container. After the heating is completed, the user needs to drink water, and then the inner cover 20 can be detached from the kettle body 10, and then the water can be poured outwards. The detachable structure is more convenient for the user to clean the kettle body 10 and the inner cover 20.

[0082] As shown in the drawings, Figure 2As shown, the inner cover 20 is further provided with an exhaust port 20b, and a pressure relief member 2 is mounted in the inner cover 20 and can move up and down relative to the exhaust port 20b, and the pressure relief member 2 is used to open or close the exhaust port 20b. When the gas pressure in the kettle body 10 is greater than a preset value, for example, greater than 40 kpa, the pressure relief member 2 can move upward under the action of the gas pressure to open the exhaust port 20b, at this time, the exhaust port 20b is in communication with the exhaust hole 20a, and the steam in the kettle body 10 can flow to the exhaust hole 20a through the exhaust port 20b, and then flow to the outside through the exhaust hole 20a. The pressure relief member 2 can open the exhaust port 20b when the gas pressure in the kettle body 10 is too large due to the failure of the waterproof breathable film 1 to function, so as to play a role in exhaust pressure relief, thereby reducing the internal pressure of the kettle body 10 and improving the safety of the liquid heating container. Of course, when the gas pressure in the kettle body 10 is too large although the waterproof breathable film 1 is not failed, the pressure relief member 2 can also open the exhaust port 20b to assist the waterproof breathable film 1 to play a role in exhaust pressure relief.

[0083] When the gas pressure in the kettle body 10 is less than or equal to a preset value, for example, less than or equal to 40 kpa, the gas pressure in the kettle body 10 is not enough to drive the pressure relief member 2 to move upward, and the pressure relief member 2 can close the exhaust port 20b, at this time, the communication between the exhaust port 20b and the exhaust hole 20a is cut off, so as to prevent the liquid in the kettle body 10 from flowing to the exhaust hole 20a through the exhaust port 20b, that is, the pressure relief member 2 can play a role in sealing and preventing water leakage.

[0084] It should be noted that the preset value of the gas pressure refers to the safe pressure value of the liquid heating container during use, and the preset value can be adjusted as needed, and the specific size of the preset value in the embodiment is not limited.

[0085] In a specific embodiment, as shown in Figure 2 The inner cover 20 includes a cover body 3 and a connecting member 4 fixedly connected, and at least part of the connecting member 4 extends into the kettle body 10 to be detachably connected with the kettle body 10, which is conducive to improving the installation stability of the inner cover 20. Specifically, the connecting member 4 can be in clamping or threaded cooperation with the inner wall of the kettle body 10. The cover body 3 and the connecting member 4 can be fixedly connected by bolts, the cover body 3 is buckled on the outside of the kettle body 10 and can play a certain role in preventing water leakage, and the exhaust hole 20a is arranged at the top of the cover body 3.

[0086] In addition, a first sealing ring 9 is arranged between the cover body 3 and the kettle body 10 to prevent the liquid or steam in the kettle body 10 from flowing to the outside between the cover body 3 and the kettle body 10, thereby improving the sealing performance of the kettle body 10.

[0087] Specifically, as shown in Figure 2As shown, the connecting piece 4 comprises a fixedly connected connecting portion 41 and a mounting portion 42, the connecting portion 41 is arranged around the circumference of the mounting portion 42, and the connecting portion 41 is used to achieve detachable connection with the kettle body 10. The mounting portion 42 is a flat plate structure, and is provided with a gas permeable hole 422. The waterproof and breathable film 1 can be fixed above or below the mounting portion 42, but the position of the waterproof and breathable film 1 should correspond to the position of the gas permeable hole 422, that is, the waterproof and breathable film 1 should cover the upper end or lower end of the gas permeable hole 422 along the axial direction Z of the inner cover 20, so that the steam in the kettle body 10 can flow to the exhaust hole 20a through the waterproof and breathable film 1 and the gas permeable hole 422. In this embodiment, the waterproof and breathable film 1 is not installed in a suspended manner, which can prevent the waterproof and breathable film 1 from vibrating, and is beneficial to improving the stability of the waterproof and breathable film 1 and prolonging the service life thereof.

[0088] In addition, in combination with Figure 3 As shown, the connecting portion 41 and the cover body 3 are further provided with a second sealing ring 43, and the mounting portion 42 and the cover body 3 are further provided with a third sealing ring 44, so as to improve the sealing effect between the connecting piece 4 and the cover body 3.

[0089] As shown in the drawings, Figure 4 As shown, the exhaust port 20b is also arranged on the mounting portion 42 and is arranged in a spaced manner with the gas permeable hole 422. The pressure relief piece 2 comprises a fixedly connected main body portion 21 and a blocking portion 22, the blocking portion 22 is arranged around the circumference of the main body portion 21, and at least part of the main body portion 21 is located in the exhaust port 20b. The mounting portion 42 is further provided with an abutting portion 421, which is arranged around the circumference of the exhaust port 20b. The blocking portion 22 is used to move away from the abutting portion 421 when the main body portion 21 moves upward relative to the exhaust port 20b, so as to open the exhaust port 20b, and the blocking portion 22 is also used to abut against the abutting portion 421 when the main body portion 21 moves downward relative to the exhaust port 20b, so as to close the exhaust port 20b.

[0090] Specifically, when the gas pressure inside the kettle body 10 is greater than a preset value, the pressure relief piece 2 can move upward relative to the exhaust port 20b under the action of the gas pressure, so that the blocking portion 22 moves away from the abutting portion 421, and the steam can flow from the gap between the blocking portion 22 and the abutting portion 421 to the exhaust hole 20a, thereby achieving the opening of the exhaust port 20b. When the gas is discharged, the gas pressure inside the kettle body 10 is less than the preset value, and the pressure relief piece 2 can move downward relative to the exhaust port 20b to reset, until the blocking portion 22 abuts against the abutting portion 421 to achieve sealing cooperation, thereby achieving the closing of the exhaust port 20b. In the process of the pressure relief piece 2 moving up and down relative to the exhaust port 20b, the main body portion 21 can be limited and matched with the inner wall of the exhaust port 20b, so as to improve the stability of the pressure relief piece 2.

[0091] Further, as shown in the drawings, Figure 4As shown, the abutment part 421 may be provided with a first guide slope 421a, and the sealing part 22 may be provided with a second guide slope 221 corresponding to the first guide slope 421a. During the process of the pressure relief member 2 moving up and down relative to the exhaust port 20b, the first guide slope 421a and the second guide slope 221 can cooperate to guide and restrict the movement of the pressure relief member 2 in its radial direction, thereby improving the movement stability of the pressure relief member 2.

[0092] like Figure 4 As shown, the inner cover 20 also includes a return spring 5, which abuts against both the cover body 3 and the pressure relief component 2. When the pressure relief component 2 moves upward under gas pressure, it compresses the return spring 5. When the gas pressure decreases, the pressure relief component 2 moves downward to reset under the restoring force of the return spring 5. Specifically, one of the cover body 3 and the pressure relief component 2 is provided with a spring mounting post 31, and the other is provided with a limiting groove 23. One end of the return spring 5 is installed on the spring mounting post 31, and the other end is installed on the limiting groove 23. The spring mounting post 31 can limit the return spring 5 along its radial direction, thereby improving the stability of the return spring 5. Of course, both the cover body 3 and the pressure relief component 2 can also be provided with spring mounting posts 31, or both can be provided with limiting grooves 23.

[0093] In this embodiment, the preset value of gas pressure can be adjusted by replacing the reset spring 5 of different specifications or the pressure relief component 2 of different specifications.

[0094] In one specific implementation, such as Figure 2 and Figure 3 As shown, the inner lid 20 also includes a filter screen 6, which is fixedly connected to the end of the connecting part 41 near the body 10. The filter screen 6 has multiple filter holes 61, allowing steam and liquid inside the body 10 to flow through the filter holes 61 to the exhaust port 20b and the waterproof and breathable membrane 1. In other words, the filter screen 6 effectively filters food residue and impurities. Furthermore, when the liquid is heated, the filter screen 6 prevents boiling water or steam from directly impacting the waterproof and breathable membrane 1, thus extending its service life.

[0095] In one specific implementation, such as Figure 2 and Figure 3 As shown, the cover 3 includes a body 32 and a decorative piece 33 fixedly connected together. The body 32 is provided with a mounting groove 321, and the side wall of the decorative piece 33 is fixedly connected to the mounting groove 321, so that the middle part of the decorative piece 33 is suspended above the body 32. The vent 20a is provided on the suspended part of the decorative piece 33. Specifically, the decorative piece 33 can be a thin stainless steel sheet, which can shorten the flow path of steam and facilitate the steam to be discharged. The body 32 can be a thicker metal or plastic part to ensure the structural strength of the cover 3.

[0096] As shown in Figure 2 The liquid heating container further comprises an outer cover 30, which is buckled on the outer side of the inner cover 20 and plays a role of dust prevention. There is a gap between the inner wall of the outer cover 30 and the outer wall of the cover body 3. When the liquid heating container heats the liquid, the steam at the exhaust hole 20a can flow to the gap and then flow to the outside through the gap, that is, the outer cover 30 can guide the steam, and the temperature of the outer cover 30 is relatively low, which can condense part of the steam and reduce the risk of high-temperature steam scalding the user. After heating is completed, the user can take down the outer cover 30 to use it as a drinking cup when he needs to drink water, thereby improving the practicability of the liquid heating container.

[0097] In a specific embodiment, the outer cover 30 is provided with a first magnetic member 7, and the inner cover 20 is provided with a second magnetic member 8. When the outer cover 30 is buckled on the inner cover 20, the outer cover 30 and the inner cover 20 can be magnetically connected through the first magnetic member 7 and the second magnetic member 8, thereby improving the stability of the outer cover 30 and preventing the outer cover 30 from falling off. Figure 3 and Figure 4 As shown in

[0098] As shown in Figure 5 The liquid heating container further comprises a handle 40, which is fixedly connected with the kettle body 10 through a limiting ring 50. The user can take or move the liquid heating container through the handle 40, and the use is more convenient. The limiting ring 50 and the outer cover 30 are provided with an exhaust passage, so that the steam between the inner cover 20 and the outer cover 30 can be exhausted to the outside.

[0099] In a specific embodiment, as shown in Figure 5 The circuit board assembly 102 comprises a gas pressure detection member 102a and a circuit board 102b, and the circuit board 102b is electrically connected with the gas pressure detection member 102a and the heating disc assembly 101 respectively. Specifically, the circuit board 102b has a control module, the input end of the control module is electrically connected with the gas pressure detection member 102a, and the output end of the control module is electrically connected with the heating disc assembly 101.

[0100] The bottom wall of the kettle body 10 is provided with a communication port 10a in communication with the outside, the air pressure detection member 102a can detect the outside air pressure through the communication port 10a, and transmit the air pressure data to the control module, the control module can obtain the local boiling point value through formula calculation or table lookup according to the local air pressure value, so as to control the heating temperature or heating time of the heating disc assembly 101, so that the liquid heating container can be used in different altitudes and different air pressure areas, and the liquid in the kettle body 10 will not boil for a long time, which is beneficial to improve the use experience of the user.

[0101] Among them, the air pressure detection member 102a can be an air pressure chip provided with an air pressure sensor, or other forms of devices, and the present embodiment does not limit this.

[0102] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
