[0037] The technical solution of the present invention has the following advantages:

[0038] 1. The present invention provides a kettle, comprising: a kettle body, comprising an inner cavity for containing water; a two-way valve, comprising a first branch pipe and a second branch pipe respectively connected to the inner cavity, and a third branch pipe simultaneously connected to the first branch pipe and the second branch pipe, when the third branch pipe is under negative pressure or positive pressure relative to the inner cavity, the first branch pipe or the second branch pipe is alternately connected.

[0039] When there is water in the kettle body, the third branch is controlled to have a negative pressure relative to the inner cavity. At this time, the first branch is connected to the third branch, the second branch is closed, and the water in the inner cavity of the kettle body flows to the third branch to be discharged. When water needs to be added to the inner cavity of the kettle body, the third branch is controlled to have a positive pressure relative to the inner cavity. At this time, the first branch is closed, the second branch is connected to the third branch, and water is delivered to the inner cavity of the kettle body through positive pressure to achieve automatic water inlet. The kettle of this solution has the dual functions of automatic water inlet and automatic water discharge, which increases the convenience of the kettle, meets user needs, and improves user experience.

[0040] 2. In the kettle provided by the present invention, the first branch pipe and the second branch pipe are respectively closed by the first seal and the second seal, and a closed space is formed in the two-way valve when the first seal and the second seal are in a closed state, and the first seal and the second seal are respectively located on the inside and outside of the closed space.

[0041] The first seal is located on the inner side of the closed space. When the third branch is under negative pressure, that is, the closed space is under negative pressure, the first seal is pushed open to the inside of the closed space by external pressure, so that the first branch is connected to the third branch. At the same time, the second branch is firmly pressed to the outside of the closed space by external pressure, so it is in a closed state. When the third branch is under positive pressure, that is, the closed space is under positive pressure, the first seal is firmly pressed to the inside of the closed space by internal pressure, so the first branch is in a sealed state. At the same time, the second branch is pushed outward from the inside of the closed space and is connected, so the second branch is in a state of being connected to the third branch. Thereby, when the closed space is under negative pressure or positive pressure relative to the inner cavity, the first branch or the second branch is alternately connected.

[0042] 3. In the kettle provided by the present invention, the first branch pipe includes: a first sealing gasket, which is arranged between the first sealing member and the opening of the first branch pipe.

[0043] The first sealing gasket improves the sealing performance of the first sealing member and provides a buffer when the first sealing member is in contact with the first sealing gasket for sealing.

[0044] 4. In the kettle provided by the present invention, the first branch pipe also includes: a drainage spring, supporting the first sealing member between the drainage spring and the first sealing gasket.

[0045] The drainage spring provides support force for the first sealing member to maintain a sealed state, and ensures that after drainage is completed, the negative pressure state of the third branch pipe is eliminated, and the drainage spring returns to its original state, thereby pushing the first sealing member to re-seal.

[0046] 5. In the kettle provided by the present invention, the first branch pipe further includes: a tray, clamped between the first sealing member and the drainage spring, and the tray is slidably connected in the first branch pipe.

[0047] The tray is slidably connected in the first branch pipe and supports the first sealing member, thereby limiting the movement of the first sealing member.

[0048] 6. The kettle provided by the present invention, the tray comprises: a base plate, one end of which is used to support the first seal, and the other end of which is used to resist the drainage spring; a limiting wall, which is arranged on the outer edge of the base plate facing the inner wall of the first branch pipe, and the limiting wall is slidingly connected to the inner wall of the first branch pipe, and the limiting wall is annular and surrounds and constitutes a space for accommodating the first seal and / or the drainage spring; at least one water-permeable gap is arranged on the limiting wall, passing through the tray, so that the limiting wall forms an incomplete ring.

[0049] The limiting wall plays a role of sliding limiting, and the water-permeable gap prevents the tray from blocking the two-way valve.

[0050] 7. In the kettle provided by the present invention, the two-way valve further comprises: a bracket, disposed in the first branch pipe and / or the third branch pipe, supporting the drainage spring so that the drainage spring is clamped between the bracket and the tray.

[0051] The bracket is connected to the inner wall of the first branch pipe or the third branch pipe to support the drainage spring, preventing the drainage spring from moving downward with the first seal and the tray, so that the drainage spring further undergoes elastic deformation when the first seal moves downward.

[0052] 8. In the kettle provided by the present invention, the second branch pipe comprises: a second sealing gasket, which is arranged on the inner wall of the second branch pipe and is located between the opening end of the second branch pipe connected to the third branch pipe and the second sealing member.

[0053] The second sealing gasket improves the sealing performance of the second sealing member.

[0054] 9. In the kettle provided by the present invention, the second branch pipe further comprises: a water inlet spring, which is arranged in the second branch pipe to prevent the second sealing member from opening.

[0055] The water inlet spring provides support for the second sealing component to ensure that the second sealing component is in a sealing state.

[0056] 10. The kettle provided by the present invention further includes: a water inlet pipe, the second branch pipe is connected to the inner cavity of the kettle body through the water inlet pipe, and the water inlet pipe is arranged in the handle.

[0057] The water inlet pipe is arranged in the handle, which saves space and reduces manufacturing costs. If the water inlet pipe is arranged at the bottom of the kettle body, or at the side of the kettle body close to the bottom, the sealing problem of the water inlet pipe itself needs to be considered. In addition, the structure of the bottom of the kettle body is complex and the space is relatively compact, which is not conducive to further laying out the water inlet pipe. In contrast, it is simple to assemble on the handle, and the conduit can be directly connected, thereby reducing labor and material costs, etc., and because the structure is simpler than the layout at the bottom of the kettle, its product life and reliability are higher.

[0058] 11. The kettle provided by the present invention further includes: a middle tube, one end of which is used to connect to the third branch pipe, and the other end is connected to a water pump.

[0059] The water pump controls the negative pressure in the third branch pipe through the middle pipe or adds water to form a positive pressure.

[0060] 12. In the kettle provided by the present invention, the third branch pipe comprises: a sealing block, which is arranged on the inner wall of the third branch pipe, and the middle pipe contacts the sealing block for sealing.

[0061] The sealing block improves the sealing performance of the connection between the middle pipe and the third branch pipe.

[0062] 13. The kettle provided by the present invention further includes: a temperature controller, which is arranged at the bottom of the kettle body, and the two-way valve is arranged on the temperature controller.

[0063] The thermostat is located at the bottom of the kettle, and the two-way valve is located on the thermostat. When the thermostat is fixed to the bottom of the kettle through the bottom cover, the two-way valve can be indirectly pressed, which is not only convenient for assembly but also can achieve a better sealing effect. When the two-way valve is set in the middle of the thermostat, the kettle is placed on the base for heating and boiling water, as well as automatic water inlet and drainage. The kettle can work normally even if it rotates 360° on the base, which meets the user experience.

[0064] 14. The kettle provided by the present invention further includes: a base, including a coupler for adapting to the temperature controller, and a middle tube for connecting to the third branch pipe is provided in the coupler.

[0065] The coupler and the thermostat are adapted to each other.

[0066] 15. In the kettle provided by the present invention, a through hole is provided at the bottom of the inner cavity for the first branch pipe to pass through, and a sealing ring is sandwiched between the first branch pipe and the through hole.

[0067] The sealing ring improves the sealing performance of the two-way valve, that is, the end where the first branch of the two-way valve is connected to the inner cavity of the kettle body. BRIEF DESCRIPTION OF THE DRAWINGS

[0082] Example 1

[0083] This embodiment provides a kettle, such as Figure 1 , Figure 2As shown, it comprises: a kettle body 1, including an inner cavity for containing water; a two-way valve 2, including a first branch pipe 21 and a second branch pipe 22 respectively connected to the inner cavity, and a third branch pipe 23 connected to the first branch pipe 21 and the second branch pipe 22 at the same time, and when the third branch pipe 23 is under negative pressure or positive pressure relative to the inner cavity, the first branch pipe 21 or the second branch pipe 22 is alternately connected. When there is water in the kettle body 1, the third branch pipe 23 is controlled to have a negative pressure relative to the inner cavity, at this time, the first branch pipe 21 is connected to the third branch pipe 23, and the second branch pipe 22 is closed, and the water in the inner cavity of the kettle body 1 flows to the third branch pipe 23 and is discharged. When water needs to be added to the inner cavity of the kettle body 1, the third branch pipe 23 is controlled to have a positive pressure relative to the inner cavity, at this time, the first branch pipe 21 is closed, and the second branch pipe 22 is connected to the third branch pipe 23, and water is sent to the inner cavity of the kettle body 1 through positive pressure, so as to realize automatic water inlet. The kettle of this solution has the dual functions of automatic water inlet and automatic water discharge, which increases the convenience of the kettle, meets user needs, and improves user experience.

[0084] In this embodiment, Figure 1 , Figure 5 As shown, the first branch pipe 21 and the second branch pipe 22 are respectively closed by the first seal 24 and the second seal 25. When the first seal 24 and the second seal 25 are in a closed state, a closed space is formed in the two-way valve 2. The first seal 24 and the second seal 25 are respectively located on the inside and outside of the closed space. The first seal 24 is located on the inside of the closed space. When the third branch pipe 23 is under negative pressure, that is, the closed space is under negative pressure, the first seal 24 is pushed into the closed space by the external pressure, so that the first branch pipe 21 is connected with the third branch pipe 23. At the same time, the second branch pipe 22 is firmly pressed on the outside of the closed space by the external pressure, so it is in a closed state. When the third branch pipe 23 is under positive pressure, that is, the closed space is under positive pressure, the first seal 24 is firmly pressed on the inside of the closed space by the internal pressure, so the first branch pipe 21 is in a sealed state. At the same time, the second branch pipe 22 is pushed outward from the inside of the closed space and is connected, so the second branch pipe 22 is in a state of being connected with the third branch pipe 23. Thus, when the closed space is under negative pressure or positive pressure relative to the inner cavity, the first branch pipe 21 or the second branch pipe 22 is alternately connected.

[0085] Among them, combined Figure 3 , Figure 5 The first branch pipe 21 includes a first sealing gasket 241 disposed between the first sealing member 24 and the opening of the first branch pipe 21. The first sealing gasket 241 improves the sealing performance of the first sealing member 24 and provides a buffer when the first sealing member 24 contacts the first sealing gasket 241 for sealing.

[0086] There is no specific limitation on the shape of the first sealing pad 241. In this embodiment, Figure 5As shown, the first sealing pad 241 is annular, and the longitudinal section is trapezoidal. As an alternative embodiment, the longitudinal section of the sealing pad is circular, I-shaped or sawtooth-shaped. In this embodiment, the sealing pad is made of elastic material. As an alternative embodiment, the sealing pad is made of PCB material.

[0087] There is no specific limitation on the internal structure of the first branch pipe 21. In this embodiment, Figure 5 As shown, the first branch pipe 21 further includes: a drainage spring 27, which supports the first sealing member 24 between the drainage spring 27 and the first sealing pad 241. The drainage spring 27 provides a supporting force for the first sealing member 24 to maintain a sealed state, and ensures that after drainage is completed, the negative pressure state of the third branch pipe 23 is eliminated, and the drainage spring 27 returns to its original state, thereby pushing the first sealing member 24 to re-seal. As an alternative embodiment, the drainage spring 27 can be other elastic members.

[0088] There is no specific limitation on the internal structure of the first branch pipe 21. In this embodiment, Figure 5 As shown, the first branch pipe 21 further includes: a tray 26, which is sandwiched between the first sealing member 24 and the drainage spring 27, and the tray 26 is slidably connected in the first branch pipe 21. The tray 26 is slidably connected in the first branch pipe 21, and supports the first sealing member 24, and limits the movement of the first sealing member 24. As an alternative embodiment, the tray 26 is removed, and only the drainage spring 27 is provided, which can also achieve the function of supporting the first sealing member 24 to achieve sealing.

[0089] There is no specific limitation on the structure of the tray 26. In this embodiment, Figure 5 , Figure 6 As shown, the tray 26 includes: a base plate 261, one end of which is used to support the first sealing member 24, and the other end of which is used to resist the drainage spring 27; a limiting wall 262, which is arranged on the outer edge of the base plate 261 facing the inner wall of the first branch pipe 21, and the limiting wall 262 is slidably connected to the inner wall of the first branch pipe 21, and the limiting wall 262 is annular and surrounds and constitutes a space for accommodating the first sealing member 24 and / or the drainage spring 27; at least one water-permeable gap 263, which is arranged on the limiting wall 262 and penetrates the tray 26, so that the limiting wall 262 forms an incomplete ring. The limiting wall 262 plays a role of sliding limit, and the water-permeable gap 263 prevents the tray 26 from blocking the two-way valve 2. In this embodiment, the limiting wall 262 is divided into several parts by the water-permeable gap 263. As an alternative embodiment, the cross section of the limiting wall 262 is C-shaped.

[0090] There is no specific limitation on the internal structure of the two-way valve 2. In this embodiment, Figure 5As shown, the two-way valve 2 further includes: a bracket 28, which is arranged in the first branch pipe 21 and / or the third branch pipe 23, and supports the drain spring 27, so that the drain spring 27 is sandwiched between the bracket 28 and the tray 26. The bracket 28 is connected to the inner wall of the first branch pipe 21 or the third branch pipe 23, and supports the drain spring 27, preventing the drain spring 27 from moving downward with the first sealing member 24 and the tray 26, so that the drain spring 27 is further elastically deformed when the first sealing member 24 moves downward. Figure 7 As shown, the middle of the bracket 28 is hollowed out and has a water-permeable portion 281, so that water can smoothly pass through the bracket 28. As an alternative embodiment, the bracket 28 is integrally formed with the first branch pipe 21 and / or the third branch pipe 23, thereby forming a boss for supporting the drainage spring 27.

[0091] There is no specific limitation on the structure of the second branch pipe 22. In this embodiment, Figure 5 As shown, the second branch pipe 22 includes: a second sealing gasket 252, which is arranged on the inner wall of the second branch pipe 22 and is located between the opening end of the second branch pipe 22 connected to the third branch pipe 23 and the second sealing member 25. The second sealing gasket 252 improves the sealing performance of the second sealing member 25. In this embodiment, the longitudinal section of the second sealing gasket 252 is an I-shape. As an alternative embodiment, the longitudinal section of the second sealing gasket 252 is a circle or a sawtooth shape.

[0092] There is no specific limitation on the structure of the second branch pipe 22. In this embodiment, Figure 5 As shown, the second branch pipe 22 further includes: a water inlet spring 251, which is arranged in the second branch pipe 22 to prevent the second sealing member 25 from opening. The water inlet spring 251 provides support for the second sealing member 25 to ensure that the second sealing member 25 is in a sealed state. As an alternative embodiment, the water inlet spring 251 can be replaced by other elastic members.

[0093] There is no specific limitation on the connection structure between the second branch pipe 22 and the inner cavity of the kettle body 1. In this embodiment, Figure 1 , Figure 2As shown, it also includes: a water inlet pipe 14, through which the second branch pipe 22 is connected to the inner cavity of the kettle body 1, and the water inlet pipe 14 is arranged in the handle 13. The water inlet pipe 14 is arranged in the handle 13, which saves space and reduces manufacturing costs. If the water inlet pipe 14 is arranged at the bottom of the kettle body 1, or at the side of the kettle body 1 close to the bottom, it is necessary to consider the sealing problem of the water inlet pipe 14 itself. In addition, the structure of the bottom of the kettle body 1 is complex, and the space is relatively compact, which is not conducive to further arranging the water inlet pipe 14. In contrast, it is simple to assemble on the handle 13, and the conduit can be directly connected, thereby reducing labor and material costs, etc., and because the structure is simpler than the layout at the bottom of the kettle, its product life and reliability are higher. As an alternative embodiment, the water inlet pipe 14 is arranged outside the kettle body 1, or the water inlet pipe 14 is connected to the bottom of the kettle body 1.

[0094] In this embodiment, Figure 5 As shown, the second branch pipe 22 and the water inlet pipe 14 are plugged into each other with interference fit.

[0095] In this embodiment, Figure 3 , Figure 4 As shown, it also includes: a middle pipe 51, one end of which is used to connect to the third branch pipe 23, and the other end is connected to a water pump. The water pump controls the third branch pipe 23 to present a negative pressure or to supplement water to form a positive pressure through the middle pipe 51.

[0096] There is no specific limitation on the structure of the third branch pipe 23. In this embodiment, Figure 3 As shown in FIG. 5 , the third branch pipe 23 includes a sealing block 29, which is arranged on the inner wall of the third branch pipe 23, and the middle pipe 51 is sealed against the sealing block 29. The sealing block 29 improves the sealing performance of the connection between the middle pipe 51 and the third branch pipe 23. As an alternative embodiment, the functions of the middle pipe 51 and the third branch pipe 23 can still be achieved by removing the sealing block 29.

[0097] In this embodiment, Figure 1 , Figure 3 , Figure 4 As shown, it also includes: a thermostat 3, which is arranged at the bottom of the kettle body 1, and a two-way valve 2 is arranged on the thermostat 3. When the thermostat 3 is fixed to the bottom of the kettle body 1 through the bottom cover 4, the two-way valve 2 can be indirectly pressed, which is not only convenient for assembly but also can obtain a better sealing effect. Figure 5 When the two-way valve 2 is set in the middle of the thermostat 3, the kettle is placed on the base 6 to heat water, and automatically fill and drain water. The kettle can work normally even if it rotates 360 degrees on the base 6, which meets the user experience.

[0098] In this embodiment, Figure 1 , Figure 2As shown, it also includes: a base 6, including a coupler 5 for adapting to the thermostat 3, and a middle pipe 51 for connecting to the third branch pipe 23 is arranged in the coupler 5. The coupler 5 and the thermostat 3 are adapted to each other.

[0099] The bottom of the inner cavity is provided with a through hole for the first branch pipe 21 to pass through, and a sealing ring 12 is sandwiched between the first branch pipe 21 and the through hole. The sealing ring 12 improves the sealing performance of the two-way valve 2, that is, the end where the first branch pipe 21 of the two-way valve 2 is connected to the inner cavity of the kettle body 1.

[0100] Working process:

[0101] Water inlet process:

[0102] A signal is sent to the water pump to make the water pump deliver water to the middle pipe 51, and the water enters the two-way valve 2 through the middle pipe 51 and enters from the third branch pipe 23 of the two-way valve 2. The second sealing member 25 slides toward the second branch pipe 22 to the right side due to the water pressure, resulting in the opening between the second sealing member 25 and the second sealing gasket 25, and the water enters the inner cavity of the kettle body 1 through the water inlet pipe in the handle 13 through the second branch pipe 22, thereby realizing automatic water inlet. At the same time, the first sealing member 24 is tightly pressed on the first sealing gasket 241 by the water pressure, that is, the first sealing member 24 remains sealed during the water inlet process.

[0103] Drainage process:

[0104] A signal is sent to the water pump to cause the water pump to pump the water channel 61, so that the middle pipe 51 and the third branch pipe 23 connected to the water channel 61 are in a negative pressure state. Figure 3 , Figure 5 When the closed space is in a negative pressure state, the water pressure on the side of the first seal 24 relative to the pot body is greater than the pressure on the side of the first seal 24 facing the closed space. At this time, the first seal 24 passively moves downward, the drainage spring 27 is compressed, and the water flows down from the gap opened between the first seal 24 and the first sealing pad 241, and is discharged through the middle tube 51 and the water channel 11. The pressure on the side of the second seal 25 facing the sealed space is relatively small, and the pressure difference is only pressed on the second sealing pad 252, and it is in a sealed state during the drainage process.

[0105] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
