Abstract
Description
Technical Field
[0001] This utility model specifically relates to a foldable handle and an electric hot pot. Background Technology
[0002] In electric pressure cookers, rice cookers, and other similar appliances, if a one-piece structure is used, the lid and pot body are typically hinged together. To enable automatic opening, a torsion spring is usually installed on the hinge shaft. The torque of the torsion spring automatically flips and opens the lid. However, using a torsion spring for automatic opening requires a relatively high torque. If the torque is too low, the lid will not open to the designated position; if the torque is too high, it may injure the user or cause severe shaking of the pot. Furthermore, the torque of the torsion spring is difficult to control precisely due to limitations in manufacturing processes and structural principles. Therefore, existing technology incorporates a damper in the electric cooker. The combined action of the damper and the torsion spring ensures a smoother opening of the lid and guarantees that it opens to the designated position. The existing damper structure includes a damping shell, a damping core, and a damping cover, with damping oil filling the space between the shell and the core. A D-shaped through-hole is formed on the core, through which the damper is mounted on the rotating shaft of the electric hot pot. During the opening and closing of the cover, relative movement occurs between the damping shell and the core, and damping is achieved through the adhesion of the damping oil. In implementing and using the aforementioned electric hot pot, the inventors discovered at least the following problems with the existing technology: the damping oil itself is expensive, and it easily contaminates food, requiring a good seal. The high sealing performance requirements complicate the manufacturing process of the damper, further increasing its cost. Furthermore, the need for a D-shaped through-hole on the damping core and the requirement to machine the rotating shaft of the electric hot pot into a D-shape complicates the manufacturing process, resulting in relatively high costs and low production efficiency.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0025] The following is for reference. Figures 1 to 6 A foldable handle according to an embodiment of the present invention includes a hinge base 2, a connecting ring 201 on the hinge base 2, the connecting ring 201 having a ring opening 202 and a second limiting opening 203, and a support rod 4 having a first limiting ring 401 and a second limiting ring 402. The connecting ring 201 is positioned between the first limiting ring 401 and the second limiting ring 402. The first limiting ring 401 has a right ring opening 405, and the second limiting ring 402 has a left ring opening 406 and a first limiting opening 407. 06 is equipped with a button 7 for locking the position of the support rod 4. One end of the button 7 is provided with a button limiting block 701. The button limiting block 701 is placed in the first limiting port 407 and the second limiting port 203. The button limiting block 701 is also equipped with a limiting screw 703. The limiting screw 703 is located on the inner surface of the second limiting port 203. The first limiting ring 401 is equipped with a spring mounting seat 3. One end of the spring mounting seat 3 is placed in the connecting ring 201. The spring mounting seat 3 is provided with a spring 8. One end of the spring 8 rests on the limiting screw 703.
[0026] This structure uses a button limiting block 701 of button 7 placed in the first limiting port 407 and the second limiting port 203 to fix the hinge seat 2 and the support rod 4, preventing the support rod 4 from swinging. A limiting screw 703 is also installed in conjunction with the button limiting block 701 to restrict the position of button 7 and prevent button 7 from dislodging from the second limiting ring 402. One end of the spring 8 presses against the limiting screw 703 to reset it. That is, when the hand leaves the surface of button 7 and does not squeeze button 7, the spring 8 pushes the button limiting block 701 of button 7 back to the first limiting port 407 and the second limiting port 203, which facilitates fixing the position of the handle. It is simple to operate, has a simplified structure, and further reduces costs.
[0027] The limiting screw 703 is larger than the second limiting port 203. Under the push of the spring 8, the limiting screw 703 returns to the inner surface of the second limiting port 203, preventing the limiting screw 703 from passing through the second limiting port 203 and preventing the button 7 from disengaging from the left ring port 406. The button 7 can move left and right within the left ring port 406. When the limiting screw 703 needs to be removed or installed, the spring mounting base 3 must be removed first to provide sufficient space for removal or installation.
[0028] Specifically, the spring mounting base 3 is provided with a decorative cover 304. The decorative cover 304 is used to cover the entire spring mounting base 3. In addition, one end of the spring mounting base 3 is provided with a fastening opening 301, and the decorative cover 304 is provided with a buckle 303. The buckle 303 is fastened into the fastening opening 301 to fix the position of the decorative cover 304. A tool is inserted into the gap between the first limiting ring 401 and the decorative cover 304, and the tool is squeezed. The tool pushes the decorative cover 304 outward, causing the buckle 303 to disengage from the fastening opening 301, so that the spring mounting base 3 can be disassembled.
[0029] Specifically, the surface of the spring mounting base 3 is provided with a positioning groove 302, and the inner wall of the first limiting ring 401 is provided with an extension block 408, which is placed within the positioning groove 302. The positioning groove 302 is used to limit the position of the spring mounting base 3 and prevent the spring mounting base 3 from rotating within the first limiting ring 401. In addition, the spring mounting base 3 and the extension block 408 are connected by screws, which fix the position of the spring mounting base 3. The spring mounting base 3 is cylindrical, which facilitates the rotation of the connecting ring 201 along the surface of the spring mounting base 3 and prevents the connecting ring 201 from detaching from the spring mounting base 3.
[0030] Specifically, the spring mounting base 3 is provided with a spring mounting cavity 305, and the other end of the spring 8 is placed inside the spring mounting cavity 305. The spring mounting cavity 305 is used to restrict the position of the spring 8, and the spring 8 can be disengaged from the spring mounting cavity 305 during assembly and disassembly.
[0031] Specifically, the support rod 4 includes a lower rod housing 403 and an upper rod housing 404, which are connected by screws. Figures 1 to 6 As shown; or the lower rod housing 403 and the upper rod housing 404 are fastened together, but the fastening method is existing technology and is not shown in the attached drawings.
[0032] This utility model discloses an electric hot pot, including a pot body 1 and a pot lid 6. The pot lid 6 is installed on the pot body 1, and the pot body 1 and the pot lid 6 are connected by a foldable handle. The foldable handle includes the structure of the aforementioned foldable handle. When the button 7 is in the open state, that is, the button limiting block 701 disengages from the first limiting port 407 and the second limiting port 203, and the button limiting block 701 moves closer to the spring mounting seat 3 and compresses the spring 8, at which time the foldable handle can swing to open the pot lid 6.
[0033] Specifically, the upper surface of the pot lid 6 is provided with a pot lid connecting seat 9, and the foldable handle is connected to the pot lid connecting seat 9 by screws for fixing. The upper surface of the pot lid connecting seat 9 is provided with a handle hinge seat 901, and a handle 5 is hinged to the handle hinge seat 901. For easy opening, the pot lid can be opened by pulling the handle 5.
[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
