In addition, the cover assembly provided by the above embodiment of the present application may further have the following additional technical features:

in some embodiments, the water sealing valve comprises a water sealing disc, the water sealing disc is matched with the first sealing ring, and the pressure relief hole is formed in the water sealing disc; the first sealing ring also comprises a first sealing sheet, a second sealing sheet and a connecting ring connected between the first sealing sheet and the second sealing sheet; the first sealing sheet, the second sealing sheet and the connecting ring are encircled to form an installation groove with an inward notch, and the water sealing disc is positioned in the installation groove; the first sealing piece is located the top of water-sealing dish, and elasticity shelters from the piece and is connected with first sealing piece, and the second sealing piece is located the below of water-sealing dish, and the pressure release hole setting is dodged to the second sealing piece. So set up, elasticity shielding piece is located the top of water-sealing dish, and is located the second gasket of water-sealing dish below and avoids the pressure release hole setting, also promptly, the second gasket can not shutoff pressure release hole, and such structure makes the steam in the liquid heating container can upwards jack-up elasticity shielding piece to open the pressure release hole and realize the pressure release.

In some embodiments, the first sealing sheet is annular, the elastic shielding sheet is annular and is matched with the first sealing sheet, and the outer peripheral wall of the elastic shielding sheet is connected to the inner peripheral wall of the first sealing sheet.

In these embodiments, first gasket and elasticity are sheltered from the piece and are formed one big annular piece of little two, and first gasket is located the outer lane, and the periphery wall of elasticity is connected on the internal perisporium of first gasket, thereby make the connection between first gasket and the elasticity shelter from the piece firm, and, annular elasticity shelter from the piece area great, under the condition that has a plurality of pressure release holes, can be with a plurality of pressure release holes ring-shaped distribution, and set up and shelter from the piece corresponding position with annular elasticity on the water sealing dish, can shelter from a plurality of pressure release holes simultaneously through an annular elasticity shelter from the piece like this.

In some embodiments, the first sealing sheet is annular, and an elastic shielding sheet is connected to a position, adjacent to the pressure relief hole, on the inner peripheral wall of the first sealing sheet, and corresponds to the pressure relief hole.

In the embodiments, the elastic shielding piece is connected to the position, adjacent to the pressure relief hole, on the inner peripheral wall of the first sealing piece, so that the elastic shielding piece can shield the pressure relief hole nearby.

In some embodiments, the number of the pressure relief holes is multiple, the number of the elastic shielding pieces is multiple, the elastic shielding pieces are arranged at intervals and are in one-to-one correspondence with the pressure relief holes, the first sealing ring further comprises a connecting rib connected with the elastic shielding pieces, and the connecting rib is connected between two adjacent elastic shielding pieces or connected with one end, far away from the first sealing piece, of the elastic shielding piece. So set up for an elasticity shielding piece is established to pressure release hole upper cover, can shelter from all pressure release holes like this and realize sealedly, and elasticity shielding piece sets up at interval between the piece, can save material. In addition, a plurality of elastic shielding pieces are connected through the connecting ribs, so that the bearing capacity of the elastic shielding pieces is larger, and a better water sealing effect is achieved.

In some embodiments, the water sealing disc comprises a disc body and a mounting part arranged on the periphery of the disc body, the pressure relief hole is arranged on the disc body, the thickness of the mounting part is smaller than that of the disc body, and the outer diameter of the mounting part is 1.05 times to 1.2 times of the diameter of the mounting groove; the water sealing plate is provided with a protruding part, the first sealing sheet or the second sealing sheet is provided with a groove matched with the protruding part, and the protruding part is positioned in the groove.

In the embodiments, a circle of mounting part with smaller thickness is arranged on the periphery of the disc body, so that the first sealing ring can be conveniently mounted; further, be provided with the bulge on the water sealing dish, be provided with the recess with bulge adaptation on first gasket or the second gasket, the cooperation of bulge and recess can make first sealing washer and water sealing dish between fixed more firm, be difficult for dropping or shifting.

In some embodiments, the pressure relief hole 210 is circular, and the diameter of the pressure relief hole 210 is greater than or equal to 1.5mm and less than or equal to 3mm. With the arrangement, the circular exhaust hole has the advantages of regular shape and convenience in processing and production. In addition, the diameter of the pressure relief hole 210 is more than or equal to 1.5mm and less than or equal to 3mm, and within the range, on one hand, the problems that the pressure relief hole 210 is less than 1.5mm and is not easy to process and not easy to realize on a die are avoided, and the processing and production of the product are facilitated; on the other hand, the problem that the water sealing performance of the elastic shielding piece 340 is poor due to the fact that the diameter of the pressure relief hole 210 is larger than 3mm is avoided, liquid such as water in the liquid heating container is further prevented from flowing out of the pressure relief hole 210, and the sealing performance of the product is improved.

In some embodiments, the thickness of the elastic shielding piece 340 is equal to or less than the thickness of the first sealing piece 310. With such an arrangement, the thickness of the elastic shielding piece 340 can be equal to that of the first sealing piece 310, and can also be smaller than that of the first sealing piece 310, and the smaller the thickness of the elastic shielding piece 340 is, the easier the elastic shielding piece is to be jacked up, and the first sealing piece 310 is used for cladding and forming firm fixation on the water sealing tray 220, so the thickness of the first sealing piece 310 cannot be too thin, and therefore, the thickness of the elastic shielding piece 340 can be smaller than that of the first sealing piece 310, and the elastic shielding piece 340 can be ensured to be jacked up smoothly by steam while ensuring that the first sealing piece 310 has enough strength to be fixed on the water sealing tray 220.

In some embodiments, the thickness of the elastic shielding sheet 340 is greater than or equal to 0.8mm and less than or equal to 2mm. In this scope, elasticity of elasticity shielding piece 340 is effectual, on the one hand, has avoided elasticity shielding piece 340's thickness undersize and has leaded to the intensity poor, the problem of easy damage, and on the other hand, the thickness that has still avoided elasticity shielding piece 340 is too big and leads to the elasticity effect poor, is difficult to be washed away by steam problem.
