Description

Technical Field

[0001] The utility model relates to the field of kettles, and particularly relates to a heat-insulating kettle rotary water outlet control switch. 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] The body of the rotary kettle plug includes an upper cover, a middle seat and a lower seat. The two ends of the middle seat are respectively fixedly connected with the upper cover and the lower seat. In actual products, the upper cover, the middle seat and the lower seat are all made of metal, generally made of stainless steel or aluminum alloy materials. This is because the all-metal product has a high-end metallic texture, is heat-resistant and not easy to deform. Thus, during its actual application, the boiling water temperature in the kettle body will be conducted to the entire body, and then the temperature of the body will be further conducted to the knob, which results in relatively high temperatures on both the body and the knob. People need to rotate the knob at a relatively high temperature, which causes inconvenience in use and poses a risk of scalding. At the same time, because all-metal conducts heat quickly, it will reduce the heat preservation function of the kettle body. Summary of the Invention

[0021] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0022] Since the base includes a metal part located at the lower part and a water outlet part located at the upper part connecting the metal part; both the water outlet part and the upper cover are made of materials with heat insulation effects; there is a gap between the water outlet part and the upper cover, and the gap forms the water outlet of the flow channel.

While preventing burns by the water outlet part and the upper cover, it is also convenient to tightly screw the rotary water outlet control switch of the kettle onto the kettle body.

[0024] Second, the temperature of the water outlet part and the upper cover will not cause the high temperature generated by the heating of the metal part located at the lower part to be conducted to the knob. Therefore, the temperature of the knob will not be hot either. Thus, a person's hand can rotate the knob at a relatively low and non-hot temperature, preventing burns by the knob and being convenient to use.

[0025] Third, compared with all-metal, such as a fully stainless-steel water outlet, the water outlet of the present utility model can reduce the heat dissipation of the boiling water in the kettle body, making the kettle body more heat-insulating. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 of 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.

[0059] See Figures 1-22 As shown, a heat - resistant kettle rotary water outlet control switch includes a body 1, a knob 2, a cover 3 and a cam assembly 5.

[0060] The body 1 is provided with a flow channel 11; the body 1 includes an upper cover 101 and a base 102. The base 102 includes a metal part 17 at the lower part and a water outlet part 18 with heat - insulating function connected to the metal part 17 at the upper part; both the water outlet part 18 and the upper cover 101 are made of materials with heat - insulating function; specifically, for example, both the water outlet part 18 and the upper cover 101 are made of heat - insulating plastic. There is a gap between the water outlet part 18 and the upper cover 101, and the gap forms the water outlet of the flow channel 11; the bottom of the metal part 17 is provided with the water inlet of the flow channel 11;

[0061] The knob 2 is arranged at one end of the body 1;

[0062] The cover 3 is arranged at the other end of the body 1 and can reciprocate along the axis direction of the body 1 to open or close the water inlet of the flow channel;

[0063] The cam assembly 5 is arranged inside the body and connects the cover 3 and the knob 2. When the knob 2 rotates, it can push the cover 3 to reciprocate along the axis direction of the body 1 through the cam assembly 5. Specifically, when the cover 3 moves downward, it can open the flow channel 11, and when the cover 3 moves upward, it can close the flow channel 11.

[0064] In this way, both the water outlet part and the upper cover have heat - insulating functions and basically do not conduct temperature. Thus, in the actual use process:

[0065] Firstly, when boiling water is poured into the kettle body, the water outlet part and the upper cover themselves will not be hot. While preventing being scalded by the water outlet part and the upper cover, it is also convenient to screw the kettle rotary water outlet control switch tightly onto the kettle body;

[0066] Secondly, the temperature of the water outlet part and the upper cover will not conduct the high temperature generated by the heat of the metal part at the lower part to the knob. Thus, the temperature of the knob will not be hot either, so that people's hands can rotate the knob at a relatively low and non - hot temperature, preventing being scalded by the knob and being convenient to use;

[0067] Thirdly, compared with all - metal, such as a fully stainless - steel water outlet, the water outlet of the present utility model can reduce the heat dissipation of the boiling water in the kettle body, making the kettle body more heat - insulating; while compared with all - plastic, the metal part at the lower part of the present utility model is heat - resistant and not easy to deform, and the whole has a more high - end metallic texture.

[0068] As a specific implementation manner, a first silica gel ring 71 is provided between the metal part 17 and the water outlet part 18. The function of the first silica gel ring 71 is to prevent water from flowing out through the gap between the metal part and the water outlet part.

[0069] As a further preferred embodiment, the first silicone ring 71 is provided with a slot 711, and the end of the water outlet member 18 is inserted into the slot 711, so as to fix the first silicone ring and facilitate installation.

[0070] As a specific implementation, a second silicone ring 72 is provided between the upper cover 101 and the base 102; the function of the second silicone ring 72 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.

[0071] As a specific embodiment, the cover 3 includes a centrally arranged top rod 31 and a

[0072] The sealing plate 32 is fixedly connected; the center guide 4 is sleeved on the push rod 31, one end of the spring 6 is against the center guide 4, and the other end of the spring 6 is against the metal part 17 of the body 1; the cam assembly 5 includes an active cam 51 and a passive cam 52, the active cam 51 is connected to the knob 2; the passive cam 52 is connected to the top of the push rod 31; the active cam 51, the passive cam 52, the center guide 4 and the top of the push rod 31 are all located in the positioning hole 13 passing through the body 1, and the centers of the active cam 51, the passive cam 52, the center guide 4 and the push rod 31 are all located on the central axis 12 of the body 1. In this way, the active cam 51, the passive cam 52 and the push rod 31 are all on the central axis 12 of the body 1, the central axis symmetry of the entire product is better, and the stability of the working process located on the central axis is better.

[0073] The connection between the center guide 4 and the push rod 31 is adopted, so that one end of the spring 6 can be against the center guide 5 and the other end can be against the metal part 17 of the main body 1, so that the push rod 31 can compress the spring 6 at the position of the central axis of the main body or be pushed upward by the spring 6.

[0074] As a specific implementation, a positioning column 103 is provided in the middle of the metal part 17, and a first positioning hole 104 is provided in the positioning column 103. The first positioning hole 104, the second positioning hole passing through the water outlet part and the third positioning hole passing through the upper cover are connected to form the positioning hole of the body.

[0075] As a specific implementation, the outer wall of the positioning post 103 is provided with a plurality of protruding and spaced vertical ribs 171, and two opposite convex posts 172 are provided. Threaded holes 173 are formed in the convex posts 172; the top ends of the convex posts 172 are higher than the top ends of the vertical ribs 171; the water outlet member 18 is provided with an inner ring 181, and the inner ring 181 is provided with two opposite concave holes 182; the top ends of the vertical ribs 171 abut against the bottom surface of the inner ring 181, and the convex posts 172 are inserted into the concave holes 182. Of course, in some embodiments, the number of the convex posts 172 and the corresponding concave holes 182 can be more than three respectively. Among them, the function of the top ends of the vertical ribs 171 abutting against the bottom surface of the inner ring 181 is to have an up-and-down limiting effect; the function of the convex posts 172 being inserted into the concave holes 182 is to have a left-and-right limiting effect.

[0076] As a specific implementation, the convex post 172 is provided with a threaded hole 173, the second silicone ring 72 is provided with a mating hole 721, and a screw 19 is inserted into the concave hole 182 and passes through the mating hole 721 and is screwed into the threaded hole 173 to tightly connect the water outlet member 18, the second silicone ring 72 and the metal member 17.

[0077] As a specific implementation, the surface of the water outlet member 18 is plated with a layer of metal film. The metal member can be made of stainless steel or aluminum alloy for example. Of course, it includes this and is not limited to this, and other metal materials can be selected according to actual needs to make the metal member. Plastic plating is already a mature technology. Plating a layer of metal film on the water outlet member can be consistent with the color of the metal member, so as to form an integrated color in appearance. Although the metal film plated on the surface of the water outlet member will have a certain temperature conduction, compared with the thermal resistance generated by most of the plastics inside, the temperature conducted by the metal film can be almost ignored, and the overall water outlet member is still not hot or not scalding. Moreover, it can make the product have a more metallic texture in the overall appearance.

[0078] As a specific implementation, the bottom of the upper cover 101 is provided with a plurality of spaced grooves 105, and the inner ring 181 is connected with a plurality of corresponding horizontal ribs 183, and the horizontal ribs 105 are embedded in the grooves 105. In this way, it can play a positioning role of up-and-down limiting and left-and-right limiting for the upper cover 101 and the water outlet member 18.

[0079] As a specific implementation, the central guide member 4 is provided with a central hole 41, two opposite protrusions 42 extend along the center on both sides of the central hole 41, and corresponding ⺁-shaped grooves 311 are provided on both sides of the ejector rod 31, and the protrusions 42 are inserted and snapped into the ⺁-shaped grooves 311. In this way, it is convenient for the central guide member 4 to be detachably sleeved on the ejector rod 31.

[0080] As a specific implementation manner, 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 role in vertical guiding, so that the passive cam can only reciprocate up and down in the vertical direction.

[0081] As a specific implementation manner, a third silicone ring 73 is sleeved on the middle end of the ejector rod 31. The function of the third silicone ring 73 is to prevent water from seeping towards the ejector rod when the cover moves downward to open the flow channel.

[0082] As a specific implementation manner, a fourth silicone ring 74 is sleeved on the sealing plate 32. The function of the fourth silicone ring 74 is to prevent water from seeping towards the flow channel when the cover moves upward to close the flow channel.

[0083] As a specific implementation manner, the anti-scalding 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 disk 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 disk 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.

[0084] As a specific implementation manner, 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 on the edge of the knob 2, and a color marking point 108 is provided on 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 the current state can be shown as being in the open state or the closed state, which is convenient for the user to judge the current state. 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.

[0085] As a specific implementation manner, a fifth silicone ring 75 is sleeved on the outer periphery of the metal part. The anti-scalding kettle rotary water outlet control switch is screwed into the kettle cup. The function of the fifth silicone ring 75 is to prevent water from flowing out through the gap between the anti-scalding kettle rotary water outlet control switch and the kettle cup.

[0086] The working process of the anti-scalding kettle rotary water outlet control switch under a specific implementation manner is as follows:

[0087] 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 plurality of adjacent protrusions. One end of the active cam 51 provided 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. Furthermore, the peaks of the wavy pushing surface 512 of the active cam 51 will move out from the troughs 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.

[0088] 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 troughs of the wavy contact surface 522 are completely fitted, thereby pushing the cover 3 to close the flow channel 11.

[0089] A recessed 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 recessed 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 so that the peak of the wavy pushing surface 512 of the active cam 51 moves out of the recessed groove 511, and the peak of the wavy pushing surface 512 of the active cam 51 slides into the trough of the wavy contact surface 522 of the passive cam 52, and the flow channel 11 is completely closed.

[0090] During this working process, due to the heat insulation effect of the water outlet part and the upper cover, the temperature is basically not conducted. Therefore, in the actual use process, on the one hand, the water outlet part and the upper cover themselves will not be hot, which can prevent being scalded by the water outlet part and the upper cover, and at the same time, it is convenient to screw the water outlet control switch of the kettle tightly on the kettle body; on the other hand, the temperature of the water outlet part and the upper cover will not be conducted to the upper knob, so the temperature of the knob will not be hot either, and thus people's hands can rotate the knob at a relatively low and non-hot temperature, preventing being scalded by the knob and being convenient to use; on the third hand, compared with all-metal, such as a fully stainless steel water outlet, the water outlet of the present invention can reduce heat dissipation and make the kettle body more heat-insulated.

[0091] It should be noted that, in order to more clearly show the structures of the active cam and the passive cam of the present invention and the internal sectional structure, compared with other figures, Figures 14-18 the structural diagrams of the active cam and the passive cam are enlarged and shown, Figure 19The internal cross-sectional view of the anti-scald kettle's rotating water outlet control switch is shown enlarged.
