A fast heating device that is easy to replace and has high safety

Abstract

The invention discloses a convenient-to-replace immersion heater device with high safety. The immersion heater device comprises a power supply end part and a heating part arranged at the lower side of the bottom of the power supply end part, wherein a first cavity, a second cavity and a third cavity are sequentially arranged inside the power supply end part from top to bottom; a connecting groove is formed in the bottom end surface of the power supply end part; a first toothed wheel is arranged in the first cavity; the right side of the first toothed wheel is connected with a second toothed wheel in an engaged way; the top of the second toothed wheel is connected with a first driving machine; a driving shaft which penetrates through the wall body of the power supply end part and extends into the second cavity is arranged at the bottom of the first toothed wheel; a sleeve with the top fixedly connected with the driving shaft is arranged in the second cavity; an inner spiral thread cavity is arranged in the sleeve; inner spiral threads of the inner spiral thread cavity are connected with an ascending and descending block in a matched way; a first through connecting hole penetrated in the vertical direction is formed in the ascending and descending block; a second through connecting hole penetrated in the vertical direction is formed in the first toothed wheel and the driving shaft; a transfer shaft in vertical extension arrangement is arranged in the second through connecting hole; the top end of the transfer shaft is connected with a second driving machine; the bottom extension section of the transfer shaft passes through the second through connecting hole and the inner spiral thread cavity and extends into the third cavity.

Description

technical field [0001] The invention relates to the technical field of household electrical appliances, in particular to a fast heating device which is easy to replace and has high safety. Background technique [0002] As a commonly used water heating appliance, fast heating is recognized by people for its many advantages such as direct heating, convenient operation, quick introduction, energy saving and power saving, and it is used more and more widely. Damage will inevitably occur under long-term use. The traditional medium heats faster and is more integrated. If the heating tube is damaged and cannot be used, it needs to be purchased again, which increases the cost of use. There are also many existing technologies that can replace the heating tube. The heating device of the tube is fast, but its power supply part is designed to increase safety due to waterproof and leakage, and the conductive contact part is set relatively inside, which makes the heating tube prone to poo...

[0002] As a commonly used water heating appliance, fast heating is recognized by people for its many advantages such as direct heating, convenient operation, quick introduction, energy saving and power saving, and it is used more and more widely. Damage will inevitably occur under long-term use. The traditional medium heats faster and is more integrated. If the heating tube is damaged and cannot be used, it needs to be purchased again, which increases the cost of use. There are also many existing technologies that can replace the heating tube. The heating device of the tube is fast, but its power supply part is designed to increase safety due to waterproof and leakage, and the conductive contact part is set relatively inside, which makes the heating tube prone to poor contact and cannot be heated normally after replacement, making replacement difficult. Increased, unable to meet existing needs, needs to be improved
