Description

Technical Field

[0001] The utility model relates to the technical field of health-preserving kettles, in particular to a health-preserving kettle. Background Art

[0002] In modern kitchen life, health pots are increasingly used. With their precise temperature control system and preset programs, health pots are often used for stewing, such as Tremella soup and nutritious porridge. Its main processing technology is slow stewing, which can ensure that the sugar and starch in the ingredients are fully extracted into the liquid, making the drink gradually thicker and accompanied by a large amount of foam. Although the stewing process of the health pot retains the nutrition of the ingredients, it also brings the potential problem of foam overflow.

[0003] In order to solve the problem of overflow when stewing in a health pot, the prior art CN201721213292.2 proposes that an anti-overflow electrode is provided on the outer shell on the upper side of the inner liner of the health pot. When the foam contacts the anti-overflow electrode, the anti-overflow electrode is turned on, and the control board connected to the anti-overflow electrode cuts off the power supply of the heating device or reduces the heating power of the heating device, thereby preventing the foam from overflowing. However, this prior art causes the outer shell to be higher than the inner liner, and the anti-overflow electrode needs to be installed by perforating the outer shell, which makes the structural stability of the outer shell poor, and the gap between the inner liner and the outer shell is difficult to clean during use.

[0004] Some existing technologies, such as CN201820211183.5, propose to provide an anti-overflow electrode at the connection between the handle and the upper end of the inner pot, and the anti-overflow electrode extends into the boiling space of the inner pot to detect whether the foam overflows. Although this solution does not require the outer shell to be higher than the inner pot, the anti-overflow electrode of this solution cannot be removed, which makes it difficult for the user to put his hand into the boiling space of the inner pot during the cleaning process, making it difficult to clean, and the anti-overflow electrode is easily damaged during the cleaning process.

[0005] In order to solve the technical problem that the anti-overflow electrode is difficult to disassemble, the prior art has a technical solution of installing the anti-overflow electrode on the pot lid. For example, the prior art CN201410203536.3 proposes a health pot with an anti-overflow structure, in which the contact assembly is composed of a sliding seat, a slider, a rod, a contact and a spring. The sliding seat is fixed on the pot lid, the contact is connected to one end of the slider, and the other end of the slider is connected to the rod, and the spring is sleeved on the rod. The slider is located in the sliding seat and forms a sliding connection with it. The slider is connected to the probe through a wire. The wire is located in the pot lid. During the heating process, the wire is often in a high temperature environment, and the slider often moves. The distance between the slider and the probe is long, which makes the wire easy to be damaged.

[0006] Furthermore, the prior art reduces the movement of the wires or removes the wires, and begins to adopt different connection structures. For example, in the prior art CN201811617937.8, the anti-overflow electrode is arranged on the lower side of the lower pot cover, and the anti-overflow electrode extends into the boiling space of the inner pot; the connection between the inner pot and the upper end of the handle is provided with a connecting guide facing the lower pot cover, and the connecting guide is connected to the control chip. The lower pot cover is provided with an elastic ejector pin, and the anti-overflow electrode is connected to the control chip through the elastic ejector pin and the connecting guide. In this prior art, the elastic ejector pin includes a conductive touch rod and a conductive member for connecting the anti-overflow electrode and the conductive member, which is fixedly installed on the lower pot cover, and the conductive touch rod is connected to the conductive member through an elastic member, and one end of the sliding touch rod extends out of the lower pot cover. At the same time, the lower pot cover and the inner pot are installed and sealed by a silicone member, so that the cross-section of the elastic member connecting the conductive touch rod cannot be too large, otherwise it will cause excessive extrusion of the silicone member and the lower pot cover will be offset.

[0007] Therefore, the prior art makes the contact area between the conductive contact rod and the elastic member, and between the conductive member and the elastic member too small, and the resistance becomes large, resulting in serious attenuation of the anti-overflow signal in the process of passing through the conductive contact rod, the elastic member and the conductive member, affecting the detection and judgment of the control chip. In addition, the elastic member may age, deform or lose elasticity after long-term use, resulting in a further reduction in the contact area. Utility Model Content

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1-Figure 6As shown, the health-preserving kettle comprises a kettle body 2 for containing liquid, a kettle cover 1 arranged above the kettle body 2, and sometimes also comprises a power base for supporting the kettle body 2. The anti-overflow electrode 4 is arranged on the kettle cover 1, and the anti-overflow electrode 4 extends into the inner side of the kettle body 2, and is used to detect whether the foam overflows. When the anti-overflow electrode 4 contacts the foam, the anti-overflow electrode 4 is turned on and generates an anti-overflow signal, and the electrical signal of the anti-overflow electrode 4 transmits the anti-overflow signal through the conductive seat 3, the ejector assembly 5 and the connecting guide 6.

[0034] The ejector assembly 5 includes an elastic ejector 501, a conductive shell 502, and an elastic member 503. The conductive shell 502 is sheathed on the outer side wall of the elastic ejector 501, and the outer side wall of the elastic ejector 501 can slide on the inner side wall of the conductive shell 502. The conductive shell 502 and the elastic ejector 501 transmit an anti-overflow signal through contact, and the contact ends of the conductive shell 502 and the elastic ejector 501 are made of a metal material that can transmit an anti-overflow signal, so that the elastic ejector 501 can transmit an anti-overflow signal through the conductive shell 502. In some embodiments, a boss 511 may be provided on the contact surface (peripheral surface) of the elastic ejector 501 and the conductive shell 502. The conductive shell 502 is provided with a housing cavity 521 for the boss 511 to slide, and the boss 511 is provided in the housing cavity 521. The boss 511 contacts the inner wall of the housing cavity 521 and is electrically connected to transmit the anti-overflow signal. In some embodiments, the contact end between the elastic ejector pin 501 and the conductive housing 502 may be provided with a conductive lubricating coating of gold or silver.

[0035] An elastic member 503 may also be provided between the conductive housing 502 and the elastic ejector pin 501. The elastic ejector pin 501 slides in the conductive housing 502 under the action of the elastic member 503. The elastic ejector pin 501 may extend out of the conductive housing 502 and the pot cover 1 to abut against the connecting guide 6. In some embodiments, the elastic member 503 is provided between the boss 511 and the inner wall of the accommodating cavity 521; preferably, the compression amount of the elastic member 503 is greater than 1.5 mm. The elastic member 503 may be a conductive spring, which may be coaxially arranged with the elastic ejector pin 501, and the boss 511 and the inner wall of the accommodating cavity 521 may be electrically connected through the conductive spring.

[0036] In actual use, the conductive shell 502 is mounted on the first through hole of the pot cover 1, and the first through hole can limit the radial movement of the conductive shell 502. The conductive seat 3 can be fixed to the side of the conductive shell 502 away from the connecting guide 6, and the conductive seat 3 can abut against the conductive shell 502 to further limit the movement of the conductive shell 502.

[0037] In some embodiments, the first tongue 301 extending axially along the conductive shell 502 abuts against the upper side of the conductive shell 502 and realizes electrical connection, further preventing the conductive shell 502 from moving radially, and the friction between the first tongue 301 and the conductive shell 502 can prevent the conductive shell 502 from moving axially. Further, the first tongue 301 and the conductive shell 502 can be interference fit, preferably with a compression amount greater than 0.3mm, to further increase the friction between the first tongue 301 and the conductive shell 502. In some embodiments, the first tongue 301 is provided with a connection arc surface extending from the circumference of the conductive shell 502, and the conductive member abuts against the elastic ejector pin 501 through the connection arc surface and realizes electrical connection. The connection arc surface of the first tongue 301 can be formed by at least stamping or the like, or by deformation when the first tongue 301 abuts against the conductive shell 502.

[0038] In some embodiments, the conductive seat 3 further includes a limit flange 302 formed by bending downward, the limit flange 302 is located on both sides of the first tongue 301 and faces the axial end surface of the conductive shell 502, and the limit flange 302 can abut against the conductive shell 502 and achieve electrical connection, thereby preventing the conductive shell 502 from moving radially. The limit flange 302 is located on both sides of the first tongue 301, and the width of the first tongue 301 is greater than the diameter of the elastic ejector 501, so as to prevent the limit flange 302 from blocking the axial movement of the elastic ejector 501. The conductive seat 3 can be an integrally formed metal part.

[0039] In summary, compared with the prior art, in this embodiment, the direct contact between the conductive housing 502 and the elastic ejector pin 501 increases the signal transmission efficiency inside the ejector pin assembly 5. The ejector pin assembly 5 is also in direct contact with the conductive seat 3, which further increases the signal transmission efficiency and structural reliability and reduces signal attenuation.

[0040] In addition to the connection or direct contact between the overflow prevention electrode 4 and the conductive seat 3 through a wire, in some embodiments of the present invention, the overflow prevention electrode 4 is also provided with an inner bolt 304 hole, and the conductive seat 3 is provided with a second through hole 303 coaxial with the inner bolt 304 hole, and a bolt 304 is passed through the second through hole 303 and screwed into the inner bolt 304 hole of the overflow prevention electrode 4, thereby pressing the mounting guide plate and the overflow prevention electrode 4 and achieving electrical connection. In this way, the overflow prevention electrode 4 is fixed to the mounting guide plate, and a larger and more stable electrical connection is achieved through the bolt 304 and the direct contact between the overflow prevention electrode 4 and the mounting guide plate, which is used to transmit the overflow prevention signal.

[0041] Specifically, during the installation process, the anti-overflow electrode 4 can be inserted into the preset position of the pot cover 1 (the anti-overflow electrode 4 can also be overmolded with the pot cover 1), the ejector assembly 5 can be inserted into the first through hole from the inside of the pot cover 1, and then the conductive seat 3 is pressed down to abut against the upper end of the ejector assembly 5, and then the anti-overflow electrode 4 is connected with the bolt 304, so that the conductive seat 3 connects and fixes the anti-overflow electrode 4 and the ejector assembly 5. After the installation is completed, the pot cover 1 can be sealed by welding or other means to prevent water vapor from entering the interior of the pot cover 1 and affecting the work and electrical connection of the conductive seat 3, the anti-overflow electrode 4 and the ejector assembly 5.

[0042] In actual use, in order to prevent the lid 1 and the body 2 from falling off when the health-preserving kettle is tilted to pour water, a silicone piece is provided on the outer circumference of the lid 1 and the body 2. At the same time, when the lid 1 and the body 2 are closed, the elastic ejector pin 501 abuts against the connecting guide piece 6, thereby driving the lid 1 as a whole to move away from the connecting guide piece 6. In order to reduce the deviation of the lid 1, the thickness of the silicone piece on the side away from the elastic ejector pin 501 is greater than the thickness of the silicone piece on the side of the elastic ejector pin 501, so as to ensure that the lid 1 is in the center of the body 2 as much as possible.

[0043] In some embodiments, in addition to the single pot lid 1, there is also a combined cover including an inner cover and an outer cover. The inner cover is covered to the pot body 2 through the outer cover. The lower side of the outer cover can be used to install a tea basket, and the inner cover can be used to open or close the filling port of the tea basket. The conductive seat 3, anti-overflow electrode 4 and ejector assembly 5 in this embodiment can be arranged on the outer cover.

[0044] The kettle body 2 also includes an inner liner (often made of glass), and a heating device is arranged at the bottom of the inner liner.

[0045] During the manufacturing or installation process of the handle 201, the connecting guide 6 for electrical connection can be installed and connected to the inner side of the top of the handle 201 near the inner pot mouth by means of overmolding, etc. The connecting guide 6 and the top of the handle 201 have a variety of installation relationships, including but not limited to: the connecting guide 6 is located in the handle 201 (can be located at the top of the handle 201 and the inner side of the inner pot mouth of the handle 201), and the connecting guide 6 is exposed by slotting at the corresponding position to facilitate the elastic ejector 501 to abut and electrically connect; the connecting guide 6 can also be directly set on the outer surface corresponding to the handle 201 and the elastic ejector 501. In some embodiments, the heating device may include a heating element and a coupler for controlling the heating of the heating tube. The connecting guide 6 can be electrically connected to the coupler to control the operation of the coupler and the heating tube. In some embodiments, a control chip for anti-overflow detection and judgment is included, and the connecting guide 6 can be electrically connected to the control chip, and the control chip can control the heating device, and the control chip can be installed on the outer side of the side wall of the inner pot, the bottom of the kettle body 2, or in the power base. In actual use, the connecting guide piece 6 and the coupler or the control chip can be connected through a wire, and the wire can pass through the holding end of the handle 201.

[0046] In some embodiments, the electrical connection or electrical connection between different electronic components or parts can select different connection methods according to the actual usage scenarios to ensure that the current can pass smoothly, including but not limited to the following methods: wire connection, PCB routing, terminal blocks, welding and abutment connection.

[0047] In some implementations, the overflow prevention signal may include a change in current value, a change in capacitance value, etc.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations.
