Technical Field
[0001] This utility model relates to the field of connector technology, and more specifically, to waterproof connectors. Background Technology
[0002] Currently, household appliances such as electric hot pots are becoming increasingly widespread in daily life, but most of their connectors are not waterproof. During use, improper operation or accidents can easily lead to water spillage, causing water to enter the connectors. This can not only damage electrical components and affect the normal use of the equipment, but may also cause safety accidents such as electric leakage, posing a significant safety hazard.
[0003] Existing connectors have significant shortcomings in waterproof design. For example, traditional connector housings are often simply assembled from shells, and the gaps between the shells and between the knob and the shell lack effective sealing measures, easily becoming channels for moisture penetration. In addition, the connection between the cable and the shell often lacks waterproofing treatment, further increasing the risk of water ingress.
[0004] Therefore, there is an urgent need for a waterproof connector with a simple structure and reliable sealing performance to solve the problems of easy water ingress and poor waterproof effect of existing connectors, thereby improving the safety and service life of electrical appliances.

The housing is composed of a first shell and a second shell. The contact surface between the second shell and the first shell has a first protrusion, and the first shell has a corresponding first groove for the first protrusion to extend into. The bottom of the first groove is filled with a first sealing strip, and the first protrusion abuts against the first sealing strip. The temperature control knob is rotatably mounted on the first shell, and the contact surface between the first shell and the temperature control knob has a second protrusion. The corresponding position of the temperature control knob has a second groove for the second protrusion to extend into, and the bottom of the second groove is provided with a second sealing strip, and the second protrusion abuts against the second sealing strip.
[0007] By adopting the above technical solution, the gap between the first housing and the second housing is filled by the first sealing strip, and the gap between the first housing and the adjustment knob is filled by the second sealing strip, thereby achieving a seal between the first housing, the second housing and the temperature control knob, and preventing water from entering the cavity through the gap between the temperature control knob, the first housing and the second housing.
[0008] The present invention is further provided that the outer shell has a through hole for the cable to extend into the cavity, and a flexible tube covering the cable is provided in the through hole. The flexible tube is made of silicone or rubber.
[0009] The present invention is further configured such that a third protrusion protrudes from the outer wall of one end of the hose that extends into the through hole, and the first housing and the second housing have a third groove for the third protrusion to extend into, and the third protrusion abuts against the third groove, which is used to fix the hose and prevent it from falling out of the through hole, and also to seal the gap between the cable and the first housing and the second housing, so as to prevent water from entering the cavity from the through hole.
[0010] Through the above technical solution, a flexible tube made of silicone or rubber material is tightly filled between the cable and the first and second housings, effectively preventing water from entering the cavity through the gaps between the cable and the first and second housings.
[0011] The present invention is further configured such that the first sealing strip and the second sealing strip are made of silicone.
[0012] The present invention is further configured such that the first housing and the second housing are connected by screws.
