Referring to fig. 1 to 3, an embodiment of the present utility model provides a sealing and positioning structure of a switch of a water dispenser, which includes a housing 100, a sealing sleeve 102 and a rotating shaft 105, wherein a cavity is formed in the housing, a positioning member 110 is disposed in a circumferential direction of an inner sidewall of the housing 100, the sidewall of the housing 100 has a taper, and a diameter of an upper end of the housing 100 is larger than a diameter of a lower end of the housing. Optionally, the positioning element 110 is made of metal and is fixed on the inner sidewall of the housing 100 by welding, and meanwhile, the length of the positioning element 110 is smaller than the axial length of the housing 100, and the positioning element 110 does not protrude from the end of the housing 100.

Optionally, the sealing sleeve 102 is flexibly embedded in the casing 100, the outer side wall of the sealing element is matched with the inner side wall of the casing 100, the sealing sleeve 102 is provided with a notch 104 matched with the positioning element 110, two sides of the positioning element 110 are provided with matching surfaces 111, and the side wall of the notch 104 is abutted with the matching surfaces 111, so that the positioning element 110 is used for positioning the sealing sleeve 102. Optionally, the notch 104 penetrates along the axial direction of the sealing sleeve 102, meanwhile, the notch 102 may be an opening that does not penetrate through the axial direction of the sealing sleeve 102, and the notch 102 has a certain length in the axial direction of the side wall of the sealing sleeve 102, so as to help maintain the strength of the sealing sleeve 102 and avoid deformation of the sealing sleeve 102 during installation. The sealing sleeve 102 is preferably made of silica gel, meets the food sanitation requirements, and has good durability.

Optionally, a connecting pipe 101 communicating with the cavity is provided on the housing 100, a connecting hole 103 communicating with the connecting pipe 101 is provided on a side wall of the sealing sleeve 102, and the connecting pipe 101 is used for draining water. Meanwhile, a rotating shaft 105 is inserted into the sealing sleeve 102 in a rotating way, an opening 106 communicated with the connecting hole 103 is formed in the rotating shaft 105, when the rotating shaft 105 rotates, the opening 106 is communicated with the connecting hole 103 to realize water boiling, and when the rotating shaft 105 rotates, the opening 106 is disconnected from the connecting hole 103, namely sealing is realized, and the water faucet cannot discharge water. The connection hole 103 is thus in communication with the connection pipe 101 when the sealing sleeve 102 is installed. Optionally, the positioning member 110 is located on a side of the sealing sleeve 102 away from the connecting hole 103, and since the notch 104 affects the strength of the sealing sleeve 102 to some extent, the positioning member 110 is preferably disposed on a side of the sealing sleeve 102 away from the connecting hole 103, which helps to ensure equal strength on both sides of the sealing sleeve 102, and avoid excessive deformation of the sealing sleeve 102 during installation.

Referring to fig. 1, the thickness of two ends of the positioning element 110 is equal, the positioning element 110 can be fixed on the inner side wall of the shell 100 in a welding manner after being rolled by a metal plate with a certain thickness, the materials are easily obtained, and the processing process is fast. Referring to fig. 2, a positioning block 115 having unequal thicknesses at both ends may be provided, i.e., one end of the positioning block 115 near the upper portion of the case 100 has a thickness greater than that of the lower end. Because the rotating shaft 105 penetrating the sealing sleeve 102 is a cylindrical part, and the outer wall of the sealing sleeve 102 is a conical surface, the wall thickness of the upper part of the sealing sleeve 102 is larger than that of the lower part, and therefore, the thickness of one end of the upper part of the positioning block 115 is correspondingly larger than that of the lower end, which is beneficial to increasing the contact between the matching surface 111 and the side wall of the notch 104, so that the positioning is more stable, and the sealing sleeve 102 is prevented from being rolled inwards or turned over after long-term use.

Referring to fig. 3, the mating surface 111 on the positioning member 110 is arranged parallel to the radial direction of the sealing sleeve 102; on the other hand, the mating surface 111 may also be disposed parallel to the axial direction of the connection pipe 101. Optionally, an inner side surface 112 is provided on a side of the positioning element 110 near the center of the housing 100, where the inner side surface 112 is a cambered surface, and the cambered surface helps to increase the thickness of the positioning element 110 and avoid the rotating shaft 105, so as to increase the contact surface area between the mating surface 111 and the notch 104, and make the installation of the sealing sleeve 102 stable. Optionally, a rounded corner 113 is provided between the mating surface 111 and the inner side surface 112 to help avoid scratching the sealing boot 102 during installation. Optionally, a chamfer 107 is provided on the sidewall of the notch 104 near the inner sidewall of the housing 100, which facilitates injection molding of the sealing sleeve 102, avoids sharp corners, and thus tearing during demolding or installation, and facilitates installation of the sealing sleeve 102.
