Description

Technical Field

[0001] The utility model relates to the field of kettles, and particularly relates to a rotary water outlet control switch for a kettle. Background Art

[0002] After retrieval, the Chinese patent document CN212140222U discloses a rotary kettle plug, which includes a body, a knob, a sealing cover, a cam mechanism and a temperature display module. A flow channel is provided on the body. The knob is arranged at one end of the body, and the sealing cover is arranged at the other end of the body. The sealing cover can reciprocate along the central axis direction of the body to open or close the flow channel. The cam mechanism is arranged inside the body and connects the sealing cover and the knob. When the knob is rotated, the knob will push the sealing cover to reciprocate through the cam mechanism to open or close the flow channel. The temperature display module is arranged on the body for detecting and displaying the temperature.

[0003] However, by carefully analyzing the structure of the rotary kettle plug, it has an installation cavity on its body and positioning columns arranged in the installation cavity. Both the active cam and the passive cam are provided with socket holes adapted to the positioning columns. The active cam and the passive cam are both arranged in the installation cavity and are movably sleeved on the positioning columns, which makes it difficult to achieve a central connection to the sealing cover. Therefore, the passive cam is provided with an extending portion extending radially. The sealing cover includes an eccentrically arranged ejector rod and a sealing plate fixedly connected to the ejector rod. The ejector rod passes through the bottom of the installation cavity and is fixedly connected to the extending portion. That is, the eccentrically arranged ejector rod can only be fixedly connected to the extending portion of the passive cam on the side of the positioning column. Then the thickness of the sealing plate of the sealing cover gradually decreases from the side where the ejector rod is located to the other side to cooperate with the eccentric arrangement of the ejector rod, further causing eccentricity of the entire structure.

[0004] This has the following technical problems: 1. The side fixing causes eccentricity, and its center of gravity deviates outside the central axis of the body, resulting in poor stability during the working process; 2. The side fixing causes poor symmetry of the entire product relative to the central axis, making many components of its body have to be produced with asymmetric eccentric structures, requiring specific molds with eccentric settings, which also increases the production cost.

Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0054] See Figures 1 - 17 As shown, a water - kettle rotary water - discharging control switch includes a body 1, a knob 2, a sealing cover 3, a central guiding part 4, and a cam assembly 5.

[0055] The body 1 is provided with a flow channel 11;

[0056] The knob 2 is arranged at one end of the body 1;

[0057] A cover 3 is provided at the other end of the body 1 and can reciprocate along the central axis 12 of the body 1 to open or close the flow channel. The cover 3 includes a push rod 31 disposed at the center and a cover plate 32 fixedly connected to the push rod.

[0058] A central guide member 4 is sleeved on the push rod 31. One end of a spring 6 abuts against the central guide member 4, and the other end of the spring 6 abuts against the body 1.

[0059] A cam assembly 5 includes a driving cam 51 and a driven cam 52. The driving cam 51 is connected to the knob 2. The driven cam 52 is connected to the top end of the push rod 31. The driving cam 51, the driven cam 52, the central guide member 4, and the top end of the push rod 31 are all located in the positioning hole 13 penetrating through the body 1. The centers of the driving cam 51, the driven cam 52, the central guide member 4, and the push rod 31 are all located on the central axis 12 of the body 1. When the knob 2 rotates, the cover 3 can be pushed to reciprocate along the central axis 12 of the body 1 through the cam assembly 5. Specifically

[0060] when the cover 3 moves downward, the flow channel 11 can be opened, and when the cover 3 moves upward, the flow channel 11 can be closed.

[0061] Among them, the connection between the central guide member 4 and the push rod 31 is adopted, so that one end of the spring 6 can abut against the central guide member 5, and the other end can abut against the body 1, so that the push rod 31 can compress the spring 6 or be pushed upward by the spring 6 at the position of the central axis of the body.

[0062] Compared with the prior art CN212140222U, in this water kettle's rotary water outlet control switch, the driving cam 51, the driven cam 52, the central guide member 4, and the top end of the push rod 31 are all located in the positioning hole 13 penetrating through the body 1, and the centers of the driving cam 51, the driven cam 52, the central guide member 4, and the push rod 31 are all located on the central axis 12 of the body 1. Thus, the core components of the product: the driving cam 51, the driven cam 52, and the push rod 31 are all on the central axis 12 of the body 1, and the central axis symmetry of the whole product is better. At the same time, compared with the eccentric setting of the prior art, the stability of the core components during the working process on the central axis is better.

[0063] As a specific implementation manner, the central guide member 4 is provided with a central hole 41, and two opposite protrusions 42 extend along the center on both sides of the central hole 41. Corresponding L-shaped grooves 311 are provided on both sides of the push rod 31, and the protrusions 42 are inserted and snapped into the L-shaped grooves 311. In this way, it is convenient for the central guide member 4 to be detachably sleeved on the push rod 31.

[0064] As a specific implementation, a vertical groove 521 is provided on the passive cam 52, and a vertical column 14 is provided on the inner wall of the positioning hole 13 of the body 1. The vertical groove 521 is inserted into the vertical column 14. In this way, the vertical column can play a vertical guiding role, enabling the passive cam to reciprocate only in the vertical direction.

[0065] As a specific implementation, a first silica gel ring 71 is sleeved on the middle end of the ejector rod 31. The function of the first silica gel ring 71 is to prevent water from seeping into the direction of the ejector rod when the cover moves downward to open the flow channel.

[0066] As a specific implementation, a second silica gel ring 72 is sleeved on the sealing plate 32. The function of the second silica gel ring 72 is to prevent water from seeping into the direction of the flow channel when the cover moves upward to close the flow channel.

[0067] As a specific implementation, the water kettle rotary water outlet control switch further includes a temperature sensor 8. The temperature sensor 8 includes a detection rod 81 and a temperature display disc 82 connected to the detection rod 81. A one-way card 15 is provided in the body 1. The detection rod 81 passes through the one-way card 15 in the body and extends out of the cover 3. The temperature sensor 8 is used to detect the temperature and display the temperature on the temperature display disc 82. The one-way card 15 has a plurality of spaced and pressed pressing pieces, and the plurality of pressing pieces enclose a cone. The function of the one-way card is to facilitate the insertion of the detection rod but make it difficult to be pulled out.

[0068] As a specific implementation, the water kettle rotary water outlet control switch further includes a filter cover 9. The filter cover 9

[0069] is sleeved on the end of the body 1, and the detection rod 81 extends out of the filter cover 9. The function of the filter cover is to separate tea leaves and tea water when making tea and filter out tea dregs.

[0070] As a specific embodiment, the body 1 includes an upper cover 101 and a base 102, and a third silicone ring 73 is provided between the upper cover 101 and the base 102; the function of the third silicone ring 73 is to prevent water from seeping into the gap between the upper cover and the base when the cover moves downward to open the flow channel. A positioning post 103 is provided in the middle of the base 102, and a first gap 104 is formed between the outer wall of the positioning post 103 and the inner wall of the base 102. A second gap 105 is formed between the outer wall of the upper cover 101 and the inner wall of the base 102. The first gap 104 and the second gap 105 communicate to form a flow channel 11; a first positioning hole 106 penetrating through the upper cover 101 and a second positioning hole 107 penetrating through the base 102 communicate to form a positioning hole 13; the first positioning hole 106 is provided in the positioning post 103, and the ejector rod 31 is inserted into the first positioning hole 106 and connected to the passive cam 52 located in the first positioning hole 106; a part of the active cam 51 is inserted into the first positioning hole 106 and is connected to the passive cam 52 in a mating manner. In this way, the top ends of the core components of the product: the active cam 51, the passive cam 52, and the ejector rod 31 are all in the first positioning hole 106 of the positioning post of the body, and the central guide member 4 and the spring 6 are also in the first positioning hole 106, and the symmetry of the whole product relative to the central axis is better.

[0071] As a specific embodiment, a plastic gasket 16 is provided between the knob 2 and the upper cover 101, so that there is a gap between the knob 2 and the top end of the upper cover 101; an observation hole 21 is provided at the edge of the knob 2, and a color marking point 108 is provided at the top end of the upper cover 101; the color marking point can be observed through the observation hole 21. The color marking point is, for example, a green or red marking point, so that it can show whether the current state is in the open state or the closed state, which is convenient for the user to judge the current state. And the function of the plastic gasket 16 to make there be a gap between the knob 2 and the top end of the upper cover 101 is that, on the one hand, it can reduce the friction between the knob and the upper cover when the knob rotates and the wear between the knob and the upper cover, and on the other hand, it can also reduce the friction sound between the knob and the upper cover. When both the knob and the upper cover are made of metal materials, this function of reducing the friction sound is particularly obvious.

[0072] As a specific embodiment, a fourth silicone ring 74 is sleeved on the outer periphery of the base 102. The water outlet control switch of the kettle for rotating is screwed into the kettle cup. The function of the fourth silicone ring 74 is to prevent water from flowing out of the gap between the water outlet control switch of the kettle for rotating and the kettle cup.

[0073] The working process of the water outlet control switch of the kettle for rotating is as follows:

[0074] One end of the active cam 51 is provided with a wavy pushing surface 512, and one end of the passive cam 52 is provided with a wavy contact surface 522 adapted to the wavy pushing surface. Both the wavy pushing surface and the wavy contact surface are formed by a number of adjacent protrusions. One end of the active cam 51 with the wavy pushing surface 512 abuts against the wavy contact surface 522 on the passive cam 52, and the other end of the active cam 52 is fixedly connected to the knob 2. When the knob 2 rotates, it drives the active cam 51 to rotate. Then, the peaks of the wavy pushing surface 512 of the active cam 51 will move out from the valleys of the wavy contact surface 522 of the passive cam 52, and at the same time, it pushes the passive cam 52 to move downward along the central axis 12 of the body 1, thereby pushing the cover 3 to open the flow channel.

[0075] When the passive cam 52 moves downward, the passive cam 52 pushes the ejector rod 31 to move downward, and the spring 6 is compressed. The spring 6 is used to push the ejector rod 31 to reset, and then push the passive cam 52 to reset, so that the peaks of the wavy pushing surface 512 and the valleys of the wavy contact surface 522 are completely fitted, thereby pushing the cover 3 to close the flow channel 11.

[0076] A concave groove 511 is provided at the peak of the wavy contact surface of the active cam 51. When the peak of the wavy pushing surface 512 of the active cam 51 moves to the peak of the wavy contact surface 522, the peak of the wavy contact surface 522 of the passive cam 52 is positioned by the concave groove 511. At this time, stop rotating the knob 2, and the flow channel 11 is completely opened. When it is necessary to close the flow channel, just continue to rotate the knob 2 to make the peak of the wavy pushing surface 512 of the active cam 51 move out of the concave groove 511, and the peak of the wavy pushing surface 512 of the active cam 51 slides into the valley of the wavy contact surface 522 of the passive cam 52, and the flow channel 11 is completely closed.
