Heater with liquid level prompting function

Abstract

The invention belongs to the technical field of household appliances, and relates to a heater with a liquid level prompting function. The heater comprises a heater body, wherein a connecting ring is mounted on the bottom surface of the heater body, a liquid storage barrel is in threaded connection with the interior of the connecting ring, a cavity is formed in the heater body, two elastic mechanisms are mounted on the top surface of the inner wall of the cavity, switches are mounted on two sides of the heater body, a cover plate is mounted on the top surface of the liquid storage barrel, a liquid suction rod is mounted in the cover plate, a positive electrode contact head is mounted on the bottom surface of the cover plate, a buzzer is mounted on the top surface of the cover plate, one end of the positive electrode contact head is electrically connected into the buzzer, a floating ball is fixedly connected to a rotating ring, an indicator lamp is arranged on the top surface of the heater body, a heating ring is mounted in the heater body, a magnetic component is arranged in the floating ball, a Hall detection component matched with the magnetic component is arranged at the bottom of the liquid storage barrel, and when the floating ball descends to the bottom along with the liquid level, the Hall detection component detects the magnetic component and gives out a prompt. The user is prompted to replace the liquid storage barrel through liquid level detection, and the situation that the heater body is started but the mosquito repelling effect is not achieved is avoided.

Description

technical field [0001] The invention belongs to the technical field of household appliances, in particular to a heater with a liquid level prompt. Background technique [0002] Electric mosquito-repellent incense is a kind of mosquito repelling tool, and the electric heater body is indispensable as a carrier for diverging electric mosquito-repellent incense. And it is easy to use, the drug effect is uniform and stable, can be used continuously, and has a long service life, and is widely used in people's life, but there are some problems in the use of existing electric mosquito-repellent incense. [0003] The working principle of electric mosquito coils and aroma devices is generally to evaporate liquid by heating, so as to achieve the effect of repelling mosquitoes or aroma, but the existing solutions do not have a dry-burning alarm function during heating. If the liquid is not heated and the power is turned on for a long time, it will waste power And there is no mosquito r...

And it is easy to use, the drug effect is uniform and stable, can be used continuously, and has a long service life, and is widely used in people's life, but there are some problems in the use of existing electric mosquito-repellent incense

[0003] The working principle of electric mosquito coils and aroma devices is generally to evaporate liquid by heating, so as to achieve the effect of repelling mosquitoes or aroma, but the existing solutions do not have a dry-burning alarm function during heating. If the liquid is not heated and the power is turned on for a long time, it will waste power And there is no mosquito repellent effect. On the one hand, it will cause damage to the equipment. On the other hand, long-term heating may cause an electrical short circuit inside the equipment, thereby causing a fire, which seriously threatens people's lives. To heat the liquid or solid mosquito repellent material, if people choose one of the equipment to use, they need to buy another equipment repeatedly, which will increase people's mosquito repellent cost virtually. When this equipment is used, the heated gas It only volatilizes slowly on the top surface of the device, which affects the mosquito repellent effect of the device
