Heating device used for steam mop

Abstract

The invention discloses a heating device used for a steam mop. The heating device comprises a shell, a heating body, a water inlet and a steam outlet, the heating body comprises a water incoming passage, a steam outgoing passage and a U-shaped heating pipe, the water incoming passage is positioned on one side of the U-shaped heating pipe, the steam outgoing passage is positioned on the other side of the U-shaped heating pipe, the water inlet and the steam outlet are directly arranged on the heating body, and both the water incoming passage and the water outgoing passage are arranged inside the heating body. Water is sprayed into the water incoming passage through the water inlet above, is quickly vaporized and sprayed out from space below, enters an outer-side heating cavity and enters the steam outgoing passage through a steam incoming hole, steam is heated by high temperature once again, and the steam after being heated enters from the steam incoming hole above the steam outlet and then is sprayed out from space below. By the heating device, heat of the heating body can be utilized fully, steam conversion efficiency is higher, quality is higher, blockage is prevented, and performance of the heating device is improved.

Description

technical field [0001] The invention relates to a heating device, in particular to a steam heating device applied to a steam mop. Background technique [0002] The steam mop has the functions of high temperature sterilization and oil removal. By heating the water, pressure and high temperature are generated, and the high-temperature and high-pressure steam is used to directly sterilize and sterilize the home environment. Using high pressure to generate steam, it can clean and sterilize, easily deal with difficult dirt. Whether it's the old grease stains on the kitchen range hood, mold growth in the humid bathroom, or car engines and interiors, etc., the steam mop quickly removes dirt, saving time and effort, and is economical and affordable. No need to add any cleaning agent, fully in line with economic principles. [0003] Since the principle of the steam mop is to sterilize and sterilize through high-temperature and high-pressure steam, a steam heating device with an in...

Problems solved by technology

However, with this method, the coils are connected in series in the heat exchange, resulting in a large difference in temperature between the front and rear, which makes the heating efficiency and heat utilization rate of the entire steam heater lower, and at the same time reduces the dryness of the steam, and The water inlet and outlet are located on the outside of the heating tube, so the effect of converting into steam is poor. There will still be some water droplets in the steam, and the steam outlet effect is not good. At the same time, the volume of the coil is small, and the water mixed with impurities is easy to enter. Causes clogging and thus low steam generator performance
