DETAILED DESCRIPTION
[0033] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.
[0034] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for distinguishing two non-identical entities with the same name or non-identical parameters. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.
[0035] The terms "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side" used herein are merely references to the directions or positions in the accompanying drawings. These terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the scope of protection of the present invention.
[0036] like Figures 1 to 14 As shown in FIG. 1 , an embodiment of the present invention is a temperature controller comprising an upper connecting seat 1 and a lower connecting seat 2, wherein the upper connecting seat 1 is provided with a plurality of conductive copper rings 3, and the lower connecting seat 2 is provided with a plurality of conductive springs 4 electrically connected to the conductive copper rings 3. The upper connecting seat 1 is further provided with a connecting ring 5, and the inner and outer walls of the connecting ring 5 are provided with a plurality of mounting portions 6 for mounting the conductive copper rings 3, and the plurality of mounting portions 6 are distributed at intervals along the axial direction of the connecting ring 5. The lower connecting seat 2 is further provided with a connecting groove 7 for plugging with the connecting ring 5, and a conductive spring 4 is respectively provided in the connecting groove 7 at a position corresponding to each mounting portion 6.
[0037] The beneficial effects of such a setting are as follows: the temperature controller of the present invention arranges multiple conductive copper rings in layers along the axial direction of the connecting ring, and the connecting groove of the lower connecting seat independently arranges conductive spring pieces corresponding to each mounting position, so that the upper connecting seat and the lower connecting seat do not need to fix the circumferential angle when plugged in, and each conductive copper ring can still accurately contact the conductive spring piece at the corresponding axial position, completely avoiding the confusion of electrical connections caused by misalignment, and ensuring the stable transmission of the multi-functional signal of the thermostat. The connecting ring adopts a three-dimensional spatial layout compared to the planar arrangement of the mounting ring groove in the background technology, which reduces the radial occupied space and significantly reduces the radial size of the thermostat, which increases the function and reduces the volume, reduces the cost, and also supports modular increase or decrease in the number of conductive copper rings installed. It only needs to adjust the height and level of the connecting ring and add corresponding conductive spring pieces in the connecting groove to adapt to the rapid development of thermostats of different specifications.
[0038] It is further provided that two mounting portions 6 for mounting the conductive copper rings 3 are provided on the inner wall and outer wall of the connecting ring 5 , and retaining rings 8 for separating the two conductive copper rings 3 are raised in the middle of the inner wall and outer wall of the connecting ring 5 .
[0039] The beneficial effects of such a setting are as follows: in this embodiment, four conductive copper rings are installed on the connecting ring, which increases the number of poles of the temperature controller to seven poles; the retaining ring protrudes in the middle of the inner wall and the outer wall of the connecting ring to form a physical isolation zone, which strictly separates the two conductive copper rings on the same wall surface; compared with the single-layer partition block structure in the background technology, the double-wall retaining ring constitutes an independent insulation barrier between four intervals, namely two zones on the inner wall and two zones on the outer wall, which increases the creepage distance between adjacent copper rings by 200%, completely eliminating the risk of interlayer arc breakdown in high humidity environments; the retaining ring can also be used as an axial positioning reference; when installing the conductive copper ring, it can be accurately inserted into the mounting parts on both sides of the retaining ring to avoid axial stringing errors caused by manual assembly; and the retaining ring also serves as an annular reinforcement rib of the connecting ring, which significantly improves the torsional stiffness of the overall structure.
[0040] It is further provided that each conductive copper ring 3 installed on the mounting portion 6 is provided with a conductive terminal 9, and the inner wall and outer wall of the connecting ring 5 are provided with at least one clearance groove 10 for the conductive terminal 9 to pass through, and the clearance groove 10 is open toward the end of the connecting ring 5 close to the upper connecting seat 1, and the clearance groove 10 extends to the mounting portion 6 at the end of the connecting ring 5 away from the upper connecting seat 1.
[0041] The beneficial effects of this arrangement are as follows: each conductive copper ring extends to the outside of the upper connecting seat through a conductive terminal, and a recess is provided for the conductive terminal of the conductive copper ring installed at one end away from the upper connecting seat to pass through. The conductive terminal will not contact the adjacent conductive copper ring, forming an independent installation channel, and the conductive copper ring can be replaced without disassembling the connecting ring, thereby reducing maintenance costs.
[0042] It is further provided that the edges of the inner and outer walls of the connecting ring 5 at the mounting portion 6 away from the upper connecting seat 1 are both rounded 11, and each conductive copper ring 3 installed at the mounting portion 6 away from the upper connecting seat 1 is provided with an arc-shaped side contact edge 12 adapted to the rounded corner 11.
[0043] The beneficial effects of this setting are as follows: the rounded corners and the arc-shaped side edges cooperate to increase the contact area between the conductive copper ring and the connecting ring, prevent the conductive copper ring from being displaced, and make the installation more secure. The arc-shaped side edges form a smooth progressive contact guide surface. When the upper connecting seat and the lower connecting seat are plugged in at an angle, the connecting ring is subjected to the inclined plugging force, and the conductive spring clip automatically slides back into place along the arc-shaped side edges, ensuring that the conductive copper ring and the conductive spring clip always maintain surface contact and maintain reliable electrical connection. The material scratch loss during the plugging and unplugging process of the upper connecting seat and the lower connecting seat is greatly reduced, thereby extending the service life of the conductive copper ring.
[0044] It is further provided that the connecting ring 5 is fixedly connected to the upper connecting seat 1 by a fastener, the upper connecting seat 1 is provided with a mounting hole 13 that cooperates with the fastener, at least one positioning pin 14 is protruded from the connecting ring 5, and the upper connecting seat 1 is provided with at least one positioning hole 15 that is adapted to the positioning pin 14.
[0045] The beneficial effects of this arrangement are as follows: the fasteners use bolts from the existing technology to ensure that the connecting ring is firmly installed; the connecting ring is plugged into and fitted with the positioning holes of the upper connecting seat through positioning pins to guide the installation direction of the connecting ring, helping the bolts to quickly align with the mounting holes and improving assembly efficiency; in this embodiment, the connecting ring can also be fixed to the upper connecting seat by hot melt.
[0046] It is further provided that two limiting rings 16 are provided on the upper connecting seat 1, and a slot 17 for the connecting ring 5 to be inserted is formed between the two limiting rings 16. The mounting hole 13 and the positioning hole 15 are both provided in the slot 17. At least one groove 18 is recessed on the connecting ring 5, and at least one ridge 19 is protruded from the slot 17 and matched with the groove 18.
[0047] The beneficial effects of this arrangement are as follows: the two limiting rings of the upper connecting seat limit the radial installation position of the connecting ring; the slots formed by the two limiting rings can guide the connecting ring to dock quickly, ensuring the coaxiality of the connecting ring and the upper connecting seat; the connecting ring also forms a snap fit with the convex strips in the slot through the groove, limiting the circumferential installation position of the connecting ring, preventing the connecting ring from rotating and displacing in the circumferential direction, and further ensuring that the connecting ring is firmly installed.
[0048] It is further configured that a first circuit board 20 is provided on the upper connecting seat 1, and each of the conductive terminals 9 is electrically connected to the first circuit board 20; a second circuit board 21 is provided on the lower connecting seat 2, and each conductive spring 4 arranged in the connecting groove 7 is electrically connected to the second circuit board 21.
[0049] The beneficial effects of this arrangement are as follows: each conductive copper ring installed on the connecting ring is welded to the first circuit board through a conductive terminal, and multiple conductive copper rings are integrated and connected. Each conductive copper ring can also be controlled individually, which facilitates signal transmission and control of each conductive copper ring. Each conductive spring installed in the connecting groove is also welded to the second circuit board, optimizing the control circuit structure and making the internal structure of the temperature controller more streamlined. The first circuit board and the second circuit board both use PCB boards, and multiple wires are welded on the PCB board for external control modules. Each circuit can be freely controlled to achieve various functions, such as external NTC temperature measurement.
[0050] It is further provided that each conductive spring piece 4 disposed in the connection groove 7 is interference-fitted with the lower connection seat 2 .
[0051] The beneficial effects of this arrangement are as follows: the T-slot on the lower connecting seat is for the conductive spring to be inserted through, and the interference fit makes the conductive spring firmly installed and saves installation accessories, and there is no need to use separate fasteners to fix each conductive spring.
[0052] The further configuration includes a shock-absorbing component and a base 29 for installing the lower connecting seat 2, the shock-absorbing component includes a first magnetic ring 30, a second magnetic ring 31 for magnetically cooperating with the first magnetic ring 30, and a mounting bracket 32, the first magnetic ring 30 is sleeved on the outside of the upper connecting seat 1, and the mounting bracket 32 is installed on the base 29 through a locking member 33, the mounting bracket 32 is provided with a contact surface 34 that fits with the lower connecting seat 2, the mounting bracket 32 is also provided with a ring platform 35 for embedding the second magnetic ring 31, and the ring platform 35 is also extended with an abutment ring 36 for abutting the first magnetic ring 30, the mounting bracket 32 and the second magnetic ring 31 both adopt a split structure, when the upper connecting seat 1 and the lower connecting seat 2 are plugged in, the first magnetic ring 30 and the second magnetic ring 31 are magnetically cooperating, and the abutment ring 36 abuts against the bottom surface of the first magnetic ring 30.
[0053] The beneficial effects of such a setting are as follows: the present invention is applied to an electric kettle. When the upper connecting seat and the lower connecting seat are plugged in, the electric kettle starts to heat the water. When the water is heated and about to reach the boiling point, boiling will occur, causing the electric kettle to vibrate. The conductive copper ring is prone to poor contact with the conductive spring piece, thereby causing a power outage. A shock-absorbing component is provided between the upper connecting seat and the lower connecting seat to prevent the electric kettle from being powered off. The shock-absorbing component is mainly composed of a first magnetic ring and a second magnetic ring. The first magnetic ring is provided on the upper connecting seat, and the second magnetic ring is installed on the base of the lower connecting seat through a mounting bracket. When the upper connecting seat and the lower connecting seat are plugged in, the first magnetic ring and the second magnetic ring are magnetically matched, making the plugging of the upper connecting seat and the lower connecting seat more stable, and preventing the upper connecting seat and the lower connecting seat from generating relative radial Displacement to avoid poor contact between the conductive copper ring and the conductive spring piece. The mounting bracket is detachably mounted on the base through a locking piece. The locking piece adopts a screw of the existing technology, which is easy to disassemble and assemble. The contact surface of the mounting bracket increases the contact area with the lower connecting seat, making the mounting bracket more firmly installed and further increasing the shock absorption effect. The ring platform of the mounting bracket radially and circumferentially limits the first magnetic ring and the second magnetic ring, and the abutment ring of the mounting bracket axially limits the first magnetic ring and the second magnetic ring. The first magnetic ring and the second magnetic ring are more tightly magnetically attracted and separate the magnetic field from the circuit to avoid affecting the stability of the circuit. The mounting bracket and the second magnetic ring adopt a split structure, that is, it is composed of two halves on the left and right, which is not only convenient for disassembly and assembly but also can adjust the radial position of each half to ensure the effectiveness of magnetic matching.
[0054] Further provided is an electric kettle, comprising the above-mentioned thermostat, wherein the upper connecting seat 1 is provided with a live wire copper ring 22 and a neutral wire copper ring 23, the lower connecting seat 2 is provided with a live wire shrapnel 24 electrically connected to the live wire copper ring 22 and a neutral wire shrapnel 25 electrically connected to the neutral wire copper ring 23, the upper connecting seat 1 is also provided with a live wire external connecting piece 26 electrically connected to the live wire copper ring 22 and a neutral wire external connecting piece 27 electrically connected to the neutral wire copper ring 23, the electric kettle is provided with a heating plate 28, and the two ends of the heating plate 28 are respectively welded to the live wire external connecting piece 26 and the neutral wire external connecting piece 27.
[0055] The beneficial effects of this setting are as follows: the thermostat is directly connected to the heating plate through the live wire external terminal and the neutral wire external terminal, and there is no need to power them through the power cord, which optimizes the circuit structure, saves electrical connection accessories, and further saves costs.
