Description

Technical Field

[0001] This utility model relates to the field of electric hot pots, and in particular to an electrical connection structure for a pot body. Background Technology

[0002] Figure 1 and Figure 2 This describes an electrical connection structure for a pot body, comprising a pot body 4, a heating element 3, and an electrode socket 21. The heating element 3 is fixed to the lower surface of the pot body 4, and has an electrode needle 31 extending downwards at a certain angle. The electrode socket 21 is equipped with a rotatable protective baffle 213 with elastic reset. When the electrode needle 31 is not inserted, the protective baffle 213, through elastic reset, maintains the reset state of the electrode plate 212 inside the electrode socket.

[0003] When the pot body 4 is installed downwards, the inclined angle of the electrode needle 31 causes it to contact the surface of the protective baffle during its downward movement, pushing the protective baffle to gradually rotate and eventually open. Thus, as the protective baffle rotates into place, the electrode needle 31 also inserts into the electrode plate 212 of the electrode socket and connects to the power supply. Therefore, the electrode needle 31 in the prior art serves a dual function: rotating and opening the protective baffle 213 and acting as a power supply connector.

[0004] However, this structure harbors an undesirable risk: when the electrode needle pushes open the protective baffle, the baffle continues to press against the electrode needle under its elastic reset action. However, after long-term use, it has been found that this pressure may cause angular or dimensional shifts in the electrode needle. Therefore, when the electrode needle is inserted into the preset electrode plate 212, this undesirable shift can lead to a loose gap between the electrode needle and the electrode plate. During cooking, the shaking of the pot under the force of stir-frying can cause changes in this gap, leading to electrical sparks between the electrode needle and the electrode plate, resulting in localized heating, and even causing the rubber sleeves mounted on the electrode socket or electrode needle to melt at high temperatures. Therefore, there is an urgent need to design a new structure that allows the protective baffle to open without electrode needle contact. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems and provide a pot body electrical connection structure that can ensure the smooth opening of the protective baffle, while avoiding contact between the electrode needle and the protective baffle, thus preventing the electric spark from heating up.

[0006] An electrical connection structure for a pot body includes a pot body, a heating element, and an electrode socket;

[0007] The heating element is disposed on the lower surface of the pot body, and the heating element is provided with electrode needles that extend out of the lower surface of the pot body;

[0008] The electrode socket is located below the pot body and includes an outer shell, a protective baffle, and an electrode plate. The outer shell has an electrode hole, and the electrode plate is located below the electrode hole. The electrode plate is used to connect with the electrode needle for power supply. The protective baffle is rotatably and elastically reset inside the outer shell to realize the open or closed state of the electrode hole.

[0009] The lower surface of the pot body is provided with a protruding pushing part; the pushing part includes a vertically arranged pushing column, and a pressing step is provided on the side of the pushing column facing the rotation direction of the protective baffle. The downward extension length of both the pushing column and the pressing step is greater than the downward extension length of the electrode needle, and the top surface of the pressing step is lower than the end of the pushing column. The top surface is in the shape of an inclined surface or an arc surface, and the top surface faces the rotation direction of the protective baffle; the protective baffle is provided with an arc-shaped pushing surface corresponding to the pushing part;

[0010] When the pot body is moved downwards to insert the electrode needle into the electrode plate, the end of the pushing column first abuts against the arc-shaped pushing surface, pushing the protective baffle to rotate for the first time; as the end of the pushing column moves further downwards, the arc-shaped pushing surface of the protective baffle after the first rotation contacts the top surface of the pressing step; as the top surface of the pressing step gradually presses down and rotates again, the protective baffle is rotated to the state where the electrode hole is fully open, and the electrode needle, as the electrode hole is fully opened, passes through the electrode hole and contacts the electrode plate.

[0011] According to the electrical connection structure of the pot body in this application, the protective baffle is pushed open in two stages by the pushing column and the pressing step of the pushing part. The pushing column and the pressing step can cooperate with each other and support each other, so that the pushing part itself is not easy to shake when it comes into contact with the protective baffle. The end of the pushing column pushes the protective baffle to rotate initially, and the top surface of the pressing step continues to contact the arc-shaped pushing surface, forming a line contact between the surfaces. This allows the pressing step to push the protective baffle open more stably. Therefore, the two-stage pushing method of the pushing column and the pressing step can make the action of the pushing part to push open the protective baffle smoother, ensuring that the protective baffle opens smoothly, while avoiding the shaking problem caused by the electrode needle contacting the protective baffle, thereby preventing the problem of electric spark heating.

[0012] Furthermore, the outer casing is also provided with a pushing hole, the position of which is opposite to the arc-shaped pushing surface, and the pushing part extends into the pushing hole and contacts the arc-shaped pushing surface.

[0013] Furthermore, it also includes an elastic element. The protective baffle is provided with a reset shaft, and the elastic element is mounted on the reset shaft. The elastic element presses against both the protective baffle and the outer shell, and provides the protective baffle with a spring force to reset between the electrode plate and the electrode hole. The elastic element can be the spring force that enables the protective baffle to reset.

[0014] Furthermore, the elastic element is a torsion spring.

[0015] Furthermore, the protective baffle is provided with rotating shafts at both ends, and the protective baffle is rotatably mounted on the outer shell via the rotating shafts.

[0016] Furthermore, it also includes a limiting member. The outer shell is provided with a rotating hole and a rotating groove. When installing the protective baffle, the rotating shaft at one end of the protective baffle is inserted into the rotating hole, the rotating shaft at the other end is placed into the rotating groove, and then the limiting member is fixed to the outer shell to limit the rotating shaft in the rotating groove. This is an embodiment of the installation of a protective baffle according to this application.

[0017] Furthermore, the end of the rotating shaft that is inserted into the rotating hole is spherical. This spherical shape facilitates the installation of the protective baffle.

[0018] Furthermore, the heating element also includes a tube body, and a rubber sleeve is fitted at the connection between the tube body and the electrode needle. Since the electrode needle of this application does not need to contact the protective baffle, there is no problem of shaking, nor is there a problem of the rubber sleeve melting at high temperature due to shaking, allowing the rubber sleeve to be stably positioned at the connection between the tube body and the electrode needle.

[0019] Furthermore, the heating element also includes a tube body, with electrode needles at both ends of the tube body. A fixing groove is provided on the lower surface of the pot body, and the tube body is fixed in the fixing groove, with the two electrode needles arranged in parallel.

[0020] Furthermore, the pushing part is disposed between the two electrode needles. Attached Figure Description

[0035] The electrical connection structure of a pot body according to this utility model is described in conjunction with the accompanying drawings.

[0036] like Figures 3 to 14The diagram illustrates an electrical connection structure for a pot body, comprising a pot body 1, a heating element 2, and an electrode socket 3. The electrode socket 3 includes a housing 31, a protective baffle 32, and electrode plates 33. The housing 31 has multiple screw posts, and the electrode plates 33 are fixed to the housing 31 by screws. The housing 31 has electrode holes 311 and pushing holes 312. The electrode plates 33 are positioned below the electrode holes 311. The protective baffle 32 is rotatably mounted on the housing 31 and is elastically reset between the electrode plates 33 and the electrode holes 311. The protective baffle 32 has an arc-shaped pushing surface 321 corresponding to the pushing holes 312, allowing the protective baffle 32 to more easily... The heating element 2 is fixed to the lower surface of the pot body 1 and is equipped with an electrode needle 21. The lower surface of the pot body 1 has a pushing part 11, which includes a pushing post 111 and a pressing step 112 extending to one side from the pushing post 111. The shape of the pushing hole 312 matches the shape of the pushing part 11, allowing the pushing post 111 and the pressing step 112 of the pushing part 11 to smoothly extend into the pushing hole 312. The pushing post 111 and the pressing step 112 of the pushing part 11 push open the protective baffle 32 in two stages, allowing the electrode needle 21 to directly connect with the electrode plate 33. The electrode needle 21 does not need to contact the protective baffle 32, thus preventing any shaking. Figure 3 As shown, the electrode socket 3 is generally installed on the base of the cooker. The pot body 1 is installed on the base of the cooker from top to bottom and cooperates with the electrode socket 3 to form an electrical connection structure, so that the heating element 2 at the bottom of the pot body 1 can be properly connected to the power supply and work normally to heat the food inside the pot body 1. Figures 3 to 6 As shown, when the pot body 1 of this application is electrically connected to the electrode socket 3, the protective baffle 32 is first pushed open by the pushing part 11, and the pushing column 111 extends into the pushing hole 312, so that the end 1111 of the pushing column 111 abuts against the arc-shaped pushing surface 321, pushing the protective baffle 32 to rotate initially. As the end 1111 of the pushing column 111 moves further down, the arc-shaped pushing surface 321 contacts the top surface of the pressing step 112, and as the pressing step 112 moves further down, the protective baffle 32 rotates initially. The top surface of 12 is gradually pressed down, causing the protective baffle 32 to rotate again until the electrode hole 311 is fully opened. The top surface of the pressing step 112 is the contact surface 1121. The top surface of the pressing step 112 and the end 1111 of the pushing column 111 have a height difference. The top surface of the pressing step 112 is lower than the end 1111 of the pushing column 111. The contact surface 1121 always remains in contact with the arc-shaped pushing surface 321 during the process of the protective baffle 32 rotating to be fully opened.

[0037] The electrode needle 21, as the electrode hole 311 is fully opened, passes directly through the electrode hole 311 and contacts the electrode plate 33, such as... Figure 9 and Figure 10 As shown in the side view, the electrode needle 21 overlaps with the pushing part 11. The electrode needle 21 is inclined, and the top surface is sloping or arc-shaped, that is, the contact surface 1121 is an inclined plane or arc-shaped surface. The contact surface 1121 shown in the attached drawings is an inclined plane, and the electrode needle 21 and the contact surface 1121 have the same inclination angle. The auxiliary dotted line drawn down from the lower surface of the pot body 1 first intersects the electrode needle 21 and then intersects the contact surface 1121. The downward extension lengths of the pushing column 111 and the pressing step 112 are both greater than the downward extension length of the electrode needle 21. This indicates that the distance between the contact surface 1121 of the pressing step 112 and the lower surface of the pot body 1 at any position is greater than the distance between the corresponding position of the electrode needle 21 and the lower surface of the pot body 1, ensuring that the electrode needle 21 will not come into contact with the protective baffle 32.

[0038] like Figure 11 and Figure 12 As shown, the outer shell 31 is provided with a mounting base 313, the inner cavity of the mounting base 313 is connected to the electrode hole 311 and the pushing hole 312, and the protective baffle 32 is rotatably installed in the mounting base 313.

[0039] The protective baffle 32 has a fan-shaped cross-section. The middle part of the protective baffle 32, corresponding to the position of the electrode plate 33, is hollowed out. The two ends of the protective baffle 32 are provided with rotating shafts. The protective baffle 32 is rotatably mounted on the outer shell 31 through the rotating shafts. Under the push of the pusher 11, the protective baffle 32 can rotate around the rotating shaft, so that the electrode plate 33, which is housed in the hollow position of the protective baffle 32, can be exposed below the electrode hole 311, so that the electrode needle 21 can be directly inserted into the electrode hole 311. It also includes a limiting member 35. The outer shell 31 is provided with a rotating hole 3131 and a rotating groove 3132. When installing the protective baffle 32, the rotating shaft at one end of the protective baffle 32 is inserted into the rotating hole 3131, and the rotating shaft at the other end is placed into the rotating groove 3132. Then, the limiting member 35 is fixed to the outer shell 31 and the rotating shaft is limited in the rotating groove 3132.

[0040] like Figures 11 to 13 As shown in the accompanying drawings, the rotating shaft of the protective baffle 32 includes a first rotating shaft 324 and a second rotating shaft 323. The mounting base 313 is provided with a rotating hole 3131 and a rotating groove 3132. When installing the protective baffle 32, the first rotating shaft 324 is inserted into the rotating hole 3131, the second rotating shaft 323 is placed into the rotating groove 3132, and then the second rotating shaft 323 is limited in the rotating groove 3132 by the limiting member 35.

[0041] like Figure 12 and Figure 13As shown, the end of the rotating shaft inserted into the rotating hole 3131 is set to be spherical, that is, the end of the first rotating shaft 324 is set to be spherical. The spherical first rotating shaft 324 provides more space for the protective baffle 32 to move when the first rotating shaft 324 is inserted into the rotating hole 3131, so that the second rotating shaft 323 at the other end of the protective baffle 32 can be easily put into the rotating groove 3132.

[0042] like Figure 11 , Figure 12 as well as Figure 14 As shown, the limiting member 35 includes a fixing part 351, a slot part 352, and a limiting protrusion 353. The outer shell 31 is provided with a screw post, and the fixing part 351 is provided with a through hole. The fixing part 351 is fixed to the screw post by screws to fix the limiting member 35. The slot part 352 is provided with a slot, which is positioned on the edge of the mounting base 313. The limiting protrusion 353 extends directly into the rotating groove 3132 to limit the second rotating shaft 323. The end of the limiting protrusion 353 is set to an arc shape to avoid the limiting protrusion 353 affecting the rotation of the second rotating shaft 323.

[0043] like Figure 11 and Figure 12 As shown, it also includes an elastic element. The protective baffle 32 is provided with a reset shaft 322. The elastic element is installed on the reset shaft 322. The elastic element presses against the protective baffle 32 and the outer shell 31 respectively. The elastic element provides the protective baffle 32 with the elastic force to reset between the electrode plate 33 and the electrode hole 311. Preferably, the elastic element is a torsion spring 34.

[0044] like Figures 7 to 10 As shown, the heating tube 2 also includes a tube body 22. A rubber sleeve 23 is fitted at the connection between the tube body 22 and the electrode needle 21. Since the electrode needle 21 of this application does not need to contact the protective baffle 32, there will be no shaking problem. Similarly, there will be no problem of the rubber sleeve 23 melting at high temperature due to shaking. This allows the rubber sleeve 23 to be stably set at the connection between the tube body 22 and the electrode needle 21.

[0045] like Figure 8 As shown, the tube body 22 is provided with electrode needles 21 at both ends, the lower surface of the pot body 1 is provided with a fixing groove 12, the tube body 22 is fixed in the fixing groove 12, and the two electrode needles 21 are arranged in parallel, and the pushing part 11 is arranged between the two electrode needles 21.

[0046] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
