Patent Description:
The existing electronic atomizing devices such as e-cigarettes may usually atomize an atomizing liquid such as e-liquid. Generally, a ceramic base may be configured to communicate with a liquid storage space of the atomizing liquid, in this way, the atomizing liquid in the liquid storage space may permeate out from one side of the ceramic base. A heating module may be generally arranged on the other side of the ceramic substrate away from the liquid storage space of the atomizing liquid to heat and atomize the permeated atomizing liquid.

However, for the existing metal heating module, since the heating module is embedded on the surface of the ceramic base and then sintered together into a whole, and due to the difference between thermal conductivities of the heating module and the ceramic base, the heating module may be slightly separated from the ceramic after heating, which may cause problems such as uneven heating temperature when the atomizing liquid is heated in subsequent use, a poor atomization effect of the atomizing liquid, and even burnt smell and peculiar smell in severe cases. In addition, for the atomizing liquid with high viscosity, the liquid guide rate of the ceramic base will decrease, in this way, the atomizing liquid on the ceramic surface arranged on the heating module is insufficient, resulting in dry burning.

An atomizer <NUM> includes an atomization sleeve <NUM>, a mounting base <NUM>, and an atomization core <NUM>.

The atomization sleeve <NUM> includes a liquid storage cavity <NUM>, and a vent tube <NUM> is defined in the atomization sleeve <NUM>. The liquid storage cavity <NUM> is configured to store an atomizing liquid, and the vent tube <NUM> is configured to guide smoke to a mouth of a user.

The mounting base <NUM> is provided with a first pressure regulating channel <NUM>, a liquid inlet cavity <NUM>, and a smoke outlet <NUM>. The first pressure regulating channel <NUM> is circuitously defined on the periphery of the liquid inlet cavity <NUM>. The mounting base <NUM> is embedded in the atomization sleeve <NUM>, and the first pressure regulating channel <NUM> and the liquid inlet cavity <NUM> are both in communication with the liquid storage cavity <NUM>. The liquid inlet cavity <NUM> guides the atomizing liquid to the atomization core <NUM>, in this way, the atomization core <NUM> atomizes the atomizing liquid to form smoke. The vent tube <NUM> is connected to the smoke outlet <NUM>, to guide the smoke to an oral cavity of the user through the smoke outlet <NUM>.

The atomization core <NUM> is connected to the end of the mounting base <NUM> away from the liquid storage cavity <NUM> and blocks the liquid inlet cavity <NUM>, in this way, the atomization sleeve <NUM>, the mounting base <NUM>, and the atomization core <NUM> form a liquid storage space. After the atomizing liquid is stored in the liquid storage space, the atomizing liquid seals the first pressure regulating channel <NUM>.

When an outer air pressure changes or the balance between an air pressure in the liquid storage cavity <NUM> and the outer air pressure is lost due to inhalation, for example, when the air pressure in the liquid storage cavity <NUM> is excessively large, the atomizing liquid may leak between the mounting base <NUM> and the inner wall of the atomization sleeve <NUM>, or the atomizing liquid may leak from the atomization core <NUM>, or the atomizing liquid may leak from a joint between the atomization core <NUM> and the mounting base <NUM>. When the air pressure in the liquid storage cavity <NUM> is excessively low, due to the influence of a pressure difference between the inside and the outside of the liquid storage cavity <NUM>, liquid flowing of the atomizing liquid may be not smooth, and the atomization core <NUM> may generate a burnt flavor during operation due to insufficient liquid supply, bringing the user poor inhalation experience.

Further, the present disclosure provides an electronic atomizing device. Referring to <FIG> is a schematic structural view of an embodiment of an electronic atomizing device according to the present disclosure.

The atomizer <NUM> is arranged on the body assembly <NUM>, a positive electrode and a negative electrode of the power supply assembly in the body assembly <NUM> may be electrically connected to the two electrode plates <NUM> of the first connector <NUM> and the second connector <NUM> respectively, so as to form a power supply circuit to supply power to the heating element <NUM>.

Based on the above, those skilled in the art may easily understand the technical effects as follows. The heating module is embedded in the liquid absorbing element, the heating module may be tightly attached to the liquid absorbing element, in this way, the heat generated by the heating module may be quickly transferred into the liquid absorbing element. Therefore, not only the excess temperature of the heating module may be prevented, but also the rapid temperature rise of the ceramic substrate may also be ensured. In addition, the heating module may absorb heat from a surface of the liquid absorbing element, in this way, finally the surface temperature of the heating surface of the liquid absorbing element is uniform without the phenomenon of a local excess temperature. In addition, the heating module is a three-dimensional structure, the atomizing liquid in the liquid absorbing element may be preheated by the heating module, and then the temperature of the atomizing liquid may be uniformly raised, thereby improving the atomization effect of the atomizing liquid. This solution has a good heating effect for the atomizing liquid with high viscosity and poor fluidity. A plurality of through holes are defined on the heating element, the contact area between the heating element and the liquid absorbing element may be increased, in this way, the heat emitted by the heating element may be uniformly and rapidly diffused into the liquid absorbing element. In this way, the temperature of the local linear heating element may be prevented from being excessively high as a result of the heat accumulation in the local area of the linear heating element due to poor contact with the liquid absorbing element, and it may also be ensured that the liquid absorbing element may be quickly and uniformly heated. Therefore, the atomization effect of the atomizing liquid may be improved.
