Problems solved by technology

Because the cigarette will have a certain size deviation during rolling, it will be difficult to get in and out from the external heating chamber when the size of the cigarette is too large; when the size of the cigarette is too small, the external heating device cannot effectively contact the cigarette , The thermal conductivity of the isolated air layer is low, and the thermal conductivity is poor, resulting in uneven heating and poor smoke taste
The current external heating appliances are not well adapted to the size deviation of cigarettes

Embodiment 2

[0055] Figure 5 It is a structural schematic diagram of a fastener according to an embodiment of the present invention. Such as Figure 5 As shown, the difference between the cigarette heating device of the embodiment of the present invention and the first embodiment is that the fastener 2 includes a plurality of memory alloy parts 21 and at least one fixing part 22, and the fixing part 22 is used to connect two adjacent memory alloy parts 21. When multiple memory alloy parts 21 and multiple fixing parts 22 are included, the way that the memory alloy parts 21 and the fixing parts 22 are alternately connected to each other can be adopted. By controlling the temperature of different memory alloy parts 21 (for example, controlling the energization state of different memory alloy parts 21), the fastener 2 can have a variety of different forms, and the adjustment accuracy of the space size of the accommodating cavity 12 is higher. .

Embodiment 1

[0058] The cigarette heating devices in Embodiment 1 and Embodiment 2 can be applied to electronic cigarette appliances. Figure 6 It is a schematic structural diagram of an electronic cigarette device according to an embodiment of the present invention. Such as Figure 6 As shown, the electronic cigarette appliance includes a cigarette heating device, a control circuit 5 and a power supply 4 , and the control circuit 5 is used to control the working state of the heater 1 and / or the fastener 2 .

[0059] The electronic cigarette device of this embodiment includes a cigarette sensor for detecting that a cigarette 7 enters the accommodating chamber 12 and generates an entry signal. Specifically, the cigarette sensor may be a microwave sensor, an infrared sensor, or the like, which can detect the motion of an object or whether an object exists. According to the input signal, the control circuit 5 controls the power supply 4 to energize and heat the memory alloy, and the fastene...

Abstract

The embodiment of the invention discloses a cigarette heating device and an electronic cigarette. A fastener is arranged outside a heater; at least one part of the fastener is made from memory alloy,through controlling the temperature of the memory alloy, the fastener can be deformed, so that the heater is compressed to be deformed and the size of an accommodating cavity of the heater is changed,and thus the cigarette can pass through the accommodating cavity or being clamped. Therefore, the cigarette heating device can adapt to the cigarettes with different sizes, the cigarette can be automatically clamped, the heating efficiency of the cigarette is improved, and the user experience is enhanced.

Description

[0001] This application claims the priority of the Chinese patent application filed with the State Intellectual Property Office of China on September 27, 2019, with the application number 2019109260308 and the title of the invention "cigarette heating device and electronic smoking set", the entire contents of which are incorporated herein by reference Applying. technical field [0002] The invention relates to the field of electronic smoking sets, in particular to a cigarette heating device and electronic smoking sets. Background technique [0003] When ordinary cigarettes are ignited and smoked, a large amount of harmful substances will be produced at high temperatures, while heat-not-burn electronic cigarettes use heated tobacco to generate smoke, which has a lower temperature and releases fewer harmful substances. The external heating device has relatively large heating area, high heat transfer efficiency, and low heating temperature, so it is the preferred heating method...
