[0002] Common water containers, such as kettles, have a spout. A kettle stopper includes a body, a knob, and a lower cap. The stopper body is installed at the spout, and a water flow channel is formed inside the stopper. The lower cap is installed at the bottom of the stopper. The knob is located at the upper end of the body and can move around the axis of the body; the lower cap is located below the body. Rotating the knob forward a certain distance causes the lower cap to descend and open the water flow channel; continuing to rotate the knob forward causes the lower cap to rise and close the water flow channel. When the knob is rotated, it is difficult to control the rotation angle of the knob, making it difficult to accurately control the opening or closing of the water flow channel by the lower cap. Utility Model Content

[0003] The main purpose of this invention is to provide a rotary stopper and a water container, which aims to improve the problem of difficulty in accurately controlling the opening or closing of the water flow channel by the lower cover.

[0004] To achieve the above objectives, this utility model proposes a rotary stopper for installation at the spout of a kettle. The rotary stopper includes a body, a knob, and a lower cover.

[0014] When the drive seat rotates in the first direction, the sliding contact portion slides relative to the first drive surface.

[0015] In one embodiment, the sliding contact portion includes a third driving surface, the height of which increases sequentially along a first direction in the direction of the body axis; when the drive seat rotates along the first direction, the third driving surface slides relative to the first driving surface.

[0016] In one embodiment, the sliding contact portion includes a free end, which slides relative to the first driving surface when the drive seat rotates in a first direction.

[0017] In one embodiment, the sliding contact portion includes a cylindrical wall extending along the axis of the body, and a sliding column disposed on the inner or outer side of the cylindrical wall.

[0018] In one embodiment, the positioning structure includes a positioning groove that communicates with the sliding groove, and the positioning groove and the sliding groove are arranged sequentially around the circumference of the shaft; the opposite side of the first driving surface includes a second driving surface;

[0019] When the drive seat rotates in the second direction, the sliding contact portion abuts against the second drive surface, causing the slider to slide out of the positioning groove and into the sliding groove.

[0020] In one embodiment, the positioning structure includes a positioning groove that communicates with the sliding groove, and the positioning groove and the sliding groove are arranged sequentially around the axis of the body;

[0021] When the drive seat rotates in the first direction, it drives the slider to slide in the slide groove until it slides into the positioning groove.

[0023] In one embodiment, the rotary stopper further includes a torsion spring, which is coaxial with the knob. The mounting end of the torsion spring is connected to the body, and the free end of the torsion spring is connected to the knob.

[0024] In one embodiment, the rotary stopper further includes a thermometer with a probe that passes sequentially through the knob, the body, and the lower cap.

[0025] This utility model also proposes a water container, including the aforementioned rotary stopper.

[0026] The rotary stopper is used to install at the spout of the kettle body. The rotary stopper includes: a body, a knob, and a lower cover. The body has a water flow channel; the knob is located at the upper end of the body and can move around the axis of the body; the lower cover is located at the lower end of the body; the rotary stopper also includes:

[0027] A drive unit is located below the knob and connected to the knob, rotating together with the knob;

[0028] A lifting movable seat is located below the drive seat. The lifting movable seat includes a lifting structure that cooperates with the drive seat and can move up and down along the axis, a fixing structure that is connected to the lower cover, and a positioning structure that restricts the upward movement of the lifting movable seat.

[0029] A reset component, located within the main body, provides power for the upward movement of the lifting movable seat;

[0030] When the knob rotates around the axis of the body in a first direction, the lifting seat, driven by the drive seat, moves the lower cover away from the lower end of the body, opening the water flow channel; when the knob rotates around the axis of the body in a second direction, the lifting seat, driven by the reset member, moves the lower cover closer to the lower end of the body, closing the water flow channel; the first direction is opposite to the second direction.

[0031] In this invention, when the water flow channel needs to be opened, the knob is first rotated in a first direction to drive the drive seat to rotate in the first direction. When the drive seat rotates in the first direction, the lower cover descends and moves away from the lower end of the main body, thereby opening the lower opening of the water flow channel. This opening facilitates pouring water out of the kettle. After pouring, the knob is rotated in a second direction to drive the drive seat to rotate in the second direction. When the drive seat rotates in the second direction, the lower cover rises and moves closer to the main body, closing the lower opening of the water flow channel. This achieves the closure of the water flow channel. By controlling the knob to open the water flow channel when rotated in the first direction and to close the water flow channel when rotated in the second direction, the problem of accurately controlling the opening or closing of the water flow channel by the lower cover is improved.

[0052] Common water containers, such as kettles, have a spout. A kettle stopper includes a body, a knob, and a lower cap. The stopper body is installed at the spout, and a water flow channel is formed inside the stopper. The lower cap is installed at the bottom of the stopper. The knob is located at the upper end of the body and can move around the axis of the body; the lower cap is located below the body. Rotating the knob forward a certain distance causes the lower cap to descend and open the water flow channel, making it easy to pour water from the kettle. Continuing to rotate the knob forward causes the lower cap to rise and close the water flow channel. However, controlling the rotation angle of the knob while rotating it is difficult, as it is easy to over-rotate the knob. Over-rotation makes it difficult to maintain the state of the lower cap and accurately control the opening or closing of the water flow channel.

[0053] This utility model proposes a rotary stopper.

[0054] Please see Figure 1 , Figure 2 and Figure 3In one embodiment of this utility model, the rotary stopper 100 is used to install at the spout of a kettle body. The rotary stopper 100 includes a body 1, a knob 2, and a lower cover 3. The body 1 has a water flow channel 11. The knob 2 is located at the upper end of the body 1 and can move around the axis of the body 1. The lower cover 3 is located at the lower end of the body 1. The rotary stopper 100 also includes a drive seat 4, a lifting seat 5, a reset member 6, and a positioning structure 9. The drive seat 4 is located below the knob 2 and is connected to the knob 2, rotating together with the knob 2. The lifting seat 5 is located below the drive seat 4 and includes a lifting structure 511 that cooperates with the drive seat 4 and can move up and down along the axis, and a fixing structure 521 connected to the lower cover 3. The positioning structure 9 restricts the upward movement of the lifting seat 5. The reset member 6 is located inside the body 1 and provides power for the upward movement of the lifting seat 5. When the knob 2 rotates around the axis of the body 1 in the first direction, the lifting movable seat 5, driven by the drive seat 4, moves the lower cover 3 away from the lower end of the body 1, opening the water flow channel 11 (see [link]). Figure 4 , Figure 5 and Figure 6 When the knob 2 rotates around the axis of the body 1 in the second direction, the lifting movable seat 5, driven by the reset member 6, moves the lower cover 3 toward the lower end of the body 1, closing the water flow channel 11; the first direction is opposite to the second direction.

[0055] In this invention, when the water flow channel 11 needs to be opened, the knob 2 is first rotated in the first direction to drive the drive seat 4 to rotate in the first direction. When the drive seat 4 rotates in the first direction, the lower cover 3 descends and moves away from the lower end of the body 1, thereby opening the lower opening of the water flow channel 11. The water flow channel 11 is then open, facilitating the pouring of water from the kettle. After pouring, the knob 2 is rotated in the second direction to drive the drive seat 4 to rotate in the second direction. When the drive seat 4 rotates in the second direction, the lower cover 3 rises and moves closer to the body 1, thereby closing the lower opening of the water flow channel 11 and achieving the closure of the water flow channel 11. By controlling the knob 2 to open the water flow channel 11 when rotated in the first direction and to close the water flow channel 11 when rotated in the second direction, the problem of accurately controlling the opening or closing of the water flow channel 11 by the lower cover 3 is improved.

[0056] Both the first and second directions are rotational directions, and the body 1 of the stopper can be made of any material. The outer side of the body 1 can be provided with external threads to screw the body 1 onto the spout of the kettle body; alternatively, the body 1 can be directly inserted into the spout. The outer periphery of the knob 2 is provided with anti-slip textures, which help to rotate the knob 2 more stably when rotating it.

[0057] The body 1 has an inner cavity with an opening on its upper side. The drive seat 4 is disposed within the inner cavity, and the knob 2 is located above the opening of the inner cavity. The inner cavity also has a mounting ring 13, which forms a mounting cavity 131 and is integrally connected to the body 1. The water flow channel 11 is located outside the mounting cavity 131. The upper side of the mounting cavity 131 also has a baffle plate 14, located at the opening of the inner cavity of the body 1. The baffle plate 14 is detachably fixed to the mounting ring 13 by the first bolt. A water flow gap is formed between the periphery of the baffle plate 14 and the edge of the opening of the inner cavity, while the baffle plate 14 can block the water flow inside the mounting cavity 131.

[0058] Please see Figure 1 , Figure 3 and Figure 4 The inner side of the baffle plate 14 is provided with a first through hole. The upper end of the drive seat 4 passes through the first through hole and is detachably fixed to the knob 2 by a second bolt. The outer periphery of the drive seat 4 has a limiting part 42 protruding out. The upper side of the limiting part 42 abuts against the baffle plate 14, thereby limiting the height of the drive seat 4. When the knob 2 is rotated, the drive seat 4 rotates with the knob 2.

[0059] The bottom side of the main body 1 is fitted with a first sealing ring 15. The lower cover 3 includes a cover body 31 and a second sealing ring 32. Both the first sealing ring 15 and the second sealing ring 32 can be made of food-grade rubber. The cover body 31 is embedded in the second sealing ring 32. When the lower cover 3 moves upward, the outer circumference of the second sealing ring 32 can abut against the first sealing ring 15, and the inner circumference of the second sealing ring 32 can abut against the lower side of the main body 1, so as to close the lower opening of the water flow channel 11.

[0060] Please see Figure 7 and Figure 10The main body 1 has a shaft 12 extending along its axial direction. The lifting seat 5 includes a first seat body, on which the lifting structure 511 and the fixing structure 521 are provided. The first seat body is sleeved on the shaft 12, and one of the outer sidewalls of the shaft 12 and the inner sidewall of the first seat body is provided with a groove 121, while the other is provided with a slider 5111. The groove 121 extends along the axial direction of the main body 1, and the slider 5111 slides within the groove 121. By providing the slider 5111 and the groove 121, the lifting of the first seat body can be guided.

[0061] The shaft 12 is connected to the body 1. The first seat includes a first lifting seat 51 and a second lifting seat 52 that are separated from each other. The lifting structure 511 is disposed on the first lifting seat 51, and the fixing structure 521 is disposed on the second lifting seat 52. Both the first lifting seat 51 and the second lifting seat 52 are sleeved on the shaft 12. The first lifting seat 51 is located on the upper side of the second lifting seat 52. The upper side of the lower cover 3 protrudes and extends into the body 1 and is connected to the second lifting seat 52. When the lifting structure 511 cooperates with the drive seat 4, so that when the first lifting seat 51 descends, the first lifting seat 51 pushes the second lifting seat 52 downward, thereby pushing the lower cover 3 downward. When the restoring member pushes the second lifting seat 52 upward, the second lifting seat 52 drives the lower cover 3 upward. The shaft 12 can limit and guide the first lifting seat 51 and the second lifting seat 52, improving the stability of the lifting of the first lifting seat 51 and the second lifting seat 52.

[0062] A connecting rod 311 is integrally connected to the upper side of the cover 31. The connecting rod 311 is located between the inner and outer circumferences of the second sealing ring 32, and penetrates the bottom wall of the body 1 and enters the mounting cavity 131. The fixing structure 5211 includes an ear plate 5211, which is detachably fixed to the connecting rod 311 by the third bolt. The connecting rod 311 can limit the rotation of the second lifting seat 52 along the shaft 12. In addition, multiple connecting rods 311 and ear plates 5211 are provided one-to-one along the axial direction of the shaft 12, which improves the stability of the connection between the second lifting seat 52 and the lower cover 3.

[0063] In one embodiment of the present invention, the slide groove 121 is provided on the outer side wall of the shaft 12, and the slider 5111 is provided on the inner side wall of the first lifting seat 51.

[0064] In another embodiment of the present invention, the slide groove 121 is provided on the inner side wall of the first lifting seat 51, and the slider 5111 is provided on the outer side wall of the shaft 12.

[0065] The drive seat 4 includes a second seat body, the upper end of which is connected to the knob 2, and the lower end of which is provided with a drive structure. The first seat body includes a first lifting seat 51, and the lifting structure 511 is located on the upper end of the first lifting seat 51, cooperating with the drive unit to lift and / or rotate. The lifting of the first lifting seat 51 is realized through the drive unit.

[0066] Please see Figure 7 , Figure 8 and Figure 9 One of the driving structure and the lifting structure 511 includes a sliding contact portion 41, and the other includes a first driving surface 512. The height of the first driving surface 512 along the axis of the body 1 increases sequentially along a first direction. When the driving seat 4 rotates along the first direction, the sliding contact portion 41 slides relative to the first driving surface 512. When the driving seat 4 rotates, the sliding contact portion 41 can abut against the first driving surface 512, causing the sliding contact portion 41 and the first driving surface 512 to slide relative to each other, pushing the driving seat 4 and the first lifting seat 51 away from each other. Since the vertical height of the driving seat 4 is limited, the first lifting seat 51 is pushed down. The sliding contact portion 41 and the first driving surface 512 are arranged in two, three, or more sets on the periphery of the shaft 12.

[0067] When the slider 5111 is located on the outer side wall of the shaft 12, the inner side of the second lifting seat 52 is provided with a clearance groove to avoid the slider 5111.

[0068] In one embodiment of the present invention, the sliding contact portion 41 is disposed on the bottom side of the drive seat 4, and the first drive surface 512 is disposed on the upper side of the first lifting seat 51.

[0069] The sliding contact portion 41 includes a third driving surface 411, the height of which increases sequentially along a first direction in the axial direction of the body 1. When the drive seat 4 rotates along the first direction, the third driving surface 411 slides relative to the first driving surface 512. By providing the third driving surface 411, the contact area between the first driving surface 512 and the sliding contact portion 41 is increased, the pressure between the first driving surface 512 and the third driving surface 411 is reduced, and damage to the drive seat 4 and the first lifting seat 51 is reduced; thus, protection for the drive seat 4 and the first lifting seat 51 is achieved.

[0070] Please see Figure 7 In one embodiment of this utility model, the third driving surface 411 extends in the same direction as the first driving surface 512. This can further increase the contact area between the first driving surface 512 and the third driving surface 411, and reduce the pressure between the first driving surface 512 and the third driving surface 411.

[0071] Please see Figure 8 In other embodiments described in this application, the sliding contact portion 41 includes a free end 413, which slides relative to the first driving surface 512 when the drive seat 4 rotates in the first direction. If the free end 413 has an arc-shaped surface on the side near the first driving surface 512, the material used in the sliding contact portion 41 is reduced, thus lowering the cost.

[0072] Please see Figure 10 The positioning structure 9 includes a positioning groove that communicates with the slide groove 121, and the positioning groove and the slide groove 121 are sequentially arranged around the axis of the body 1. When the drive seat 4 rotates in the first direction, it drives the slider 5111 to slide in the slide groove 121 until it slides into the positioning groove. The sliding part cooperates with the first drive surface 512, which enables the first lifting seat 51 to move down while also giving the first lifting seat 51 a tendency to rotate. When the first lifting seat 51 moves down and the upper height of the slider 5111 is lower than the connection point between the positioning groove and the slide groove 121, the first lifting seat 51 rotates, which enables the slider 5111 to slide into the positioning groove. The positioning groove can limit the up and down movement of the slider 5111 so that the lower cover 3 remains in a continuously open state.

[0073] The positioning groove is a horizontally extending long groove, and the width of the positioning groove can be greater than that of the slider 5111. This allows the slider 5111 to abut against the inner wall of the positioning groove, limiting its sliding along the circumference of the shaft 12 and simultaneously limiting its upward movement. This limits the upward movement of the first lifting seat 51, thereby limiting the upward movement of the second lifting seat 52 and the lower cover 3, ensuring that the lower cover 3 remains in the open state.

[0074] The positioning groove, the sliding groove 121 and the slider 5111 correspond one-to-one with the shaft 12 in the circumferential direction and are arranged in two, three or more sets in sequence, which is not limited here.

[0075] The sliding contact portion 41 includes a cylindrical wall 414 extending along the axis of the body 1, and a sliding column 415 disposed on the inner or outer side of the cylindrical wall 414.

[0076] Please see Figure 9 The sliding contact portion 41 includes a sliding post 415. The sliding post 415 is disposed on the inner side of the cylindrical wall 414. The structure of the sliding post 415 is not limited here, as long as it can abut against the first driving surface 512 and the second driving surface 513 respectively.

[0077] Please see Figure 10 The positioning structure 9 includes a positioning groove that communicates with the slide groove 121, and the positioning groove and the slide groove 121 are arranged sequentially around the circumference of the shaft 12; the opposite side of the first driving surface 512 includes a second driving surface 513; when the driving seat 4 rotates in the second direction, the sliding contact part 41 abuts against the second driving surface 513, so that the slider 5111 slides out of the positioning groove and into the slide groove 121.

[0078] Please see Figure 10 In one embodiment of this application, both the positioning groove and the sliding groove 121 are disposed on the shaft 12, and the slider 5111 is disposed on the first lifting seat 51. In this case, the positioning groove is disposed at the bottom end of the sliding groove 121, and the sliding groove 121 and the positioning groove are sequentially arranged along the first direction. The upper sidewall of the positioning groove may be recessed, so that when the slider 5111 slides into the positioning groove, the slider 5111 moves upward with the first lifting seat 51, and the slider 5111 can abut against the upper sidewall of the positioning groove, thereby reducing the natural disengagement of the slider 5111 from the positioning groove. When an external force controls the first lifting seat 51 to rotate along the second direction, the slider 5111 can slide from the positioning groove into the sliding groove 121.

[0079] Please see Figure 11 In another embodiment of this application, the positioning groove and the sliding groove 121 are both located on the inner side of the first lifting seat 51, and the slider 5111 is located on the outer side wall of the shaft 12. In this case, the positioning groove is located at the upper end of the sliding groove 121, and the sliding groove 121 and the positioning groove are arranged sequentially along the second direction. The lower side wall of the positioning groove can be recessed. After the slider 5111 slides into the positioning groove, the slider 5111 can abut against the lower side wall of the positioning groove to prevent the slider 5111 from sliding out of the positioning groove, thereby achieving continuous limiting of the upward movement of the first lifting seat 51, so that the lower cover 3 remains in the open state.

[0080] The positioning structure 9 includes a positioning groove, and both the positioning groove and the sliding groove 121 are provided on either the shaft 12 or the first lifting seat 51. The sliding groove 121 and the positioning groove are offset from each other in the circumferential direction of the shaft 12 and are connected. One of the drive seat 4 and the lifting structure 511 has a sliding contact portion 41, and the other has a second driving surface 513. When the drive seat 4 rotates in the second direction, the sliding contact portion 41 can abut against the second driving surface 513, so that the slider 5111 slides from the positioning groove into the sliding groove 121. After rotating the knob 2 in the second direction by a certain angle, the sliding contact portion 41 can abut against the second driving surface 513. Continuing to rotate the knob 2 in the second direction, the sliding contact portion 41 can drive the first lifting seat 51 to rotate in the second direction, so that the slider 5111 disengages from the positioning groove and slides into the sliding groove 121.

[0081] Please see Figure 7 The sliding contact portion 41 is disposed on the drive seat 4, and a receiving groove is formed between the first drive surface 512 and the second drive surface 513. At least a portion of the sliding contact portion 41 is located in the receiving groove to ensure contact between the sliding contact and the first drive surface 512 or the second drive surface 513.

[0082] The sliding contact portion 41 includes a fourth driving surface 412, which can abut against the second driving surface 513. The fourth driving surface 412 increases the abutment between the fourth driving surface 412 and the second driving surface 513, thereby reducing the pressure between them.

[0083] Both the second driving surface 513 and the fourth driving surface 412 are vertical surfaces, so that when the fourth driving surface 412 abuts against the second driving surface 513, the first lifting seat 51 is only subjected to a thrust along the second direction.

[0084] Please see Figure 3 and Figure 4 The first seat includes a second lifting seat 52, and the fixing structure 521 is disposed on the second lifting seat 52. The second lifting seat 52 is disposed below the first lifting seat 51. The reset member 6 includes a reset spring, which is sleeved on the shaft 12. The upper end of the reset spring abuts against the lower side of the second lifting seat 52. Under the push of the reset spring, the second lifting seat 52 can drive the lower cover 3 to rise, so that the lower cover 3 closes the lower opening of the water flow channel 11.

[0085] The bottom side of the main body 1 is provided with a mounting hole, and the lower side of the shaft 12 has a mounting end 122. The mounting end 122 is threaded into the mounting hole, and the bottom end of the return spring abuts against the mounting end 122.

[0086] The body 1 also includes a thermometer 8, which includes a probe 81 that passes sequentially through the knob 2, the body 1, and the lower cover 3. After the rotary stopper 100 is installed on the spout, the probe 81 can be inserted into the body of the kettle to detect the water temperature inside the kettle.

[0087] The shaft 12 is a hollow shaft, and the probe 81 passes through the shaft 12. The thermometer 8 also includes a display 82. The upper side of the knob 2 has a mounting groove 71, and the display 82 is located in the mounting groove 71. The display 82 can conveniently display the water temperature in the kettle.

[0088] The rotary stopper 100 also includes a torsion spring 7, which is coaxial with the knob 2. The mounting end 122 of the torsion spring 7 is connected to the body 1, and the free end of the torsion spring 7 is connected to the knob 2. After the knob 2 is rotated in the first direction, the torsion spring 7 undergoes elastic deformation, and the knob 2 continues to rotate. When the slider 5111 slides into the positioning groove, the knob 2 is released, and the knob 2 can rotate in the second direction under the drive of the torsion spring 7, so that the sliding contact part 41 and the second driving surface 513 abut against each other. At this time, the operator only needs to rotate the knob 2 slightly in the second direction to slide the slider 5111 from the positioning groove into the slide groove 121.

[0089] Please see Figure 12 When the knob 2 is released and the slider 5111 is located within the slide groove 121, the torsion spring 7 is in its natural state to prevent the slider 5111 from sliding from the positioning groove into the slide groove 121 when the torsion spring 7 drives the knob 2 to rotate in the second direction. Alternatively, a suitable model of torsion spring 7 can be selected to prevent the torsion spring 7 from applying excessive rotational force when the knob 2 is driven to rotate in the second direction, thus preventing the slider 5111 from sliding from the positioning groove into the slide groove 121.

[0090] By incorporating a torsion spring 7, the angle at which the operator rotates the knob 2 in the second direction is reduced, thus improving the ease of operation.

[0091] The torsion spring 7 is located between the baffle plate 14 and the knob 2, and the baffle plate 14 has a baffle groove 141 formed on its upper side, which can cover the connection between the knob 2 and the drive seat 4. The torsion spring 7 is located outside the baffle plate 14, and the baffle plate 14 can limit the torsion spring 7. The mounting end 122 of the torsion spring 7 is mounted on the upper side of the baffle plate 14, and the free end of the torsion spring 7 is mounted on the lower side of the knob 2.

[0092] A washer 142 is installed on the upper side of the shielding plate 14, and the lower end of the torsion spring 7 abuts against the washer 142. A sealing ring is provided inside the mounting end 122, and the probe 81 passes through the sealing ring. The sealing ring can prevent water from leaking out of the mounting end 122.

[0093] This utility model also proposes a water container with a rotary stopper 100. The specific structure of the rotary stopper 100 is as described in the above embodiments. Since this water container adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0094] The water container includes a kettle, which has a body and a spout, and the rotary stopper 100 is installed at the spout.

[0095] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
