[0041] Furthermore, if Figure 3 、 Figure 4 As shown, the support bar 220 is rotatably mounted on the pot cover 300, and the first torsion spring 400 provides the support bar 220 with elastic force to turn the top outward. Before the seal is placed, the socket of the tube holder and the notch of the card slot are tilted outward away from the pot cover; this design can make the notch of the tube holder and the card slot face outward, so that the seal can be quickly aligned when installed, which is convenient for assembly.

[0042] Furthermore, if Figure 10 As shown, the inner wall of the pot cover 300 is provided with a first groove 310, and the edge of the first groove 310 near the rotation fulcrum is connected to the second groove 320, and the outer sides of the second groove 320 are provided with third grooves 330; the two ends of the second groove 320 are connected to the third groove 330 through a first circular hole 350; a plurality of sunken areas are provided on the wall surface of the pot cover near the pot body to provide space for the installation of the seal and the support assembly so that the pot cover can be properly closed;

[0044] The support bar is rotatably mounted in the second groove, and the cooperation of the provided clamping member and the first torsion spring provides the support bar with power to flip outward, so that the socket of the tube seat and the notch of the clamping slot are placed outward, which facilitates the assembly of the seal;

[0045] The outer wall shape of the stopper matches the shape of part of the wall of the third groove. The stopper is clamped and installed in the third groove, shielding the third groove and internal components to maintain the overall aesthetics. Notches are provided at the edges of the stopper and the third groove to facilitate prying up the stopper and disassembly and replacement of internal components.

[0046] Furthermore, if Figure 1 、 10 As shown, a fourth groove 340 is provided in the middle of the groove wall of the second groove 320 away from the first groove, and a first through hole 360 is provided on the groove wall of the fourth groove 340 away from the second groove 320, which penetrates the outer wall of the pot cover 300, and the water hose 210 is installed through the first through hole 360; a support block 370 is fixedly provided at the bottom of the fourth groove 340, and the support block extends toward the first through hole; Figure 2 As shown, a clamping block 710 is provided on the top surface of the pot body 700 at a position corresponding to the fourth groove 340. When the pot cover 300 is closed on the pot body 700, the clamping block 710 is correspondingly clamped into the fourth groove 340, so that the water hose 210 is clamped between the clamping block 710 and the support block 370, so that the internal channel of the water hose is closed; this structural design can limit the unblocking of the water hose by utilizing the usage habits of the pot cover and the pot body, so that when the pot cover is closed, the water hose is clamped by the clamping block and the support block to achieve sealing, preventing the hot air during cooking from being discharged from this part and can only be discharged from the originally designed exhaust part for its control setting; when the pot cover is opened and flipped up, it naturally returns to the conductive state, facilitating the discharge of reflux water to the outside.

[0047] Furthermore, a groove 371 is provided on the wall surface of the support block 370 close to the pot body, the bottom of the groove is an arc-shaped structure, and the two ends of the groove extend to the two opposite groove walls of the fourth groove; the top surface of the clamping block 710 is provided with an arc-shaped protrusion 720 corresponding to the groove 371; this structural design can further limit the clamping position and enhance the clamping and sealing effect of the water hose; further, the edges of the clamping block, support block and groove are provided with rounded corners to prevent the water hose from being damaged due to overly sharp edges during extrusion, thereby extending its service life.

[0048] Furthermore, if Figure 9As shown, the two ends of the water hose 210 are fixedly sleeved on the first plug 211 and the second plug 212 respectively; the first plug and the second plug are both perforated structures; the first plug 211 is threadedly installed at the insertion hole 250, and the second plug 212 is threadedly installed at the first through hole 360; the external water flows through the first plug, the water hose, and the second plug in sequence before being discharged; the water hose is a detachable structure, which is convenient for production, processing and assembly, and also easy to disassemble and replace;

The first and second magnets of this design can overcome and offset the elastic force, so that the seal can maintain overall flatness after it is installed. When the seal is removed, the support plate is out of the magnetic range of the first magnet and detached from the support assembly. The seal no longer hinders the outward swing of the support assembly. The support assembly is turned outward under the elastic force of the first torsion spring, so that the notch of the card slot and the socket of the tube seat are placed outward, which facilitates the subsequent installation of the seal.
