Description

A heating element

Technical field

The invention relates to the field of atomizers, in particular to a heating element applied to the atomizer.

Background technique

The current atomizer basically adopts a cotton-wrapped structure. The oil is soaked in the cotton-wrapped and atomized by heating the cotton-wrapped method. However, this method has its drawbacks. First of all, the cotton-wrapped oil is prone to oil leakage. The atomizer malfunctions, or causes people to inhale oil by mistake. Secondly, during the atomization process, the temperature of the heating wire and the amount of oil atomization are difficult to balance, which makes it easy to scorch the cotton bale. At the same time, due to uneven atomization, It is difficult to achieve a good release effect and affect the taste. Later, in order to improve the taste and avoid inhaling the oil by mistake, some heating elements began to appear on the market. The advantage of the heating element is that the cotton can be removed, and the oil can penetrate into the pores of the heating element more evenly, and the heating is more uniform. However, the current heating elements on the market still have their shortcomings. Most of the heating elements on the market are cup-shaped, and the cup-shaped inner space directly connects to the oil storage cavity. Limited by the cross-sectional area of the atomizer, the area where the heating element receives the oil It is small, so that the oil leakage is uneven, and the mist is often unable to release the mist smoothly. In addition, if it is made into the form of oil mist separation, usually the mist channel can only shuttle along the gap of the heating element, making the inhalation not smooth.

The lower part extends downwards from the side opposite the upper part and the notch end, so that at the same horizontal position, the lower part leaves space for the passage of the atomizer through the trachea, and the upper notch also leaves space for the passage of the trachea, so that The aerosol can walk through the airway of the trachea alone, making the inhalation smoother and enhancing the experience of use. There are several micropores for oil seepage on the upper and lower parts, so that the heating element can be heated to produce aerosol under the condition of fully absorbing oil, so that the fogging effect is better. The upper surface of the upper part is provided with an inwardly recessed oil inlet groove, which provides a sinking channel for the oil in the oil storage cavity, which can make the oil sink to the bottom of the heating element and contact the heating wire more quickly, shorten the fogging time and make the use more comfortable. it is good. The side of the lower part and the upper part of the gap is provided with a vent hole. The position of the vent hole is close to the installation position of the lower end of the nebulizer through the trachea, so that the generated mist is very close to the lower end of the nebulizer through the trachea, and the mist can enter quickly when receiving suction The atomizer passes through the lower end of the trachea and is then conducted to the suction nozzle through the atomizer through the trachea. The number of air outlets is 2, which makes the outflow channels for generating mist more concentrated, and the cross-sectional area of the mist outlet channels with only one air outlet is larger and the mist out effect is better. The lower surface is wrapped with a silicone sleeve to prevent oil leakage. The heating wire is printed or inlaid and fixed to the bottom of the lower part. Printing or inlay has its own advantages. The printing process is simple and the inlay can freely control the width of the heating wire, which is convenient to adjust the degree of heating and mist. Since there may be other mounting parts for support between the ceramic heating body and the air passage of the atomizer, the shape of the notch is compatible with the shape of the air passage of the atomizer, including the shape of the notch and the passage of the atomizer. The shape of the mounting part of the trachea is adapted. The upper outer peripheral side wall has at least one inward groove for placing a sealing ring, which can ensure the airtightness between the heating element and the oil storage cavity.
