Description

A kind of low temperature cigarette

Technical field

In particular to a kind of low temperature cigarette of the utility model.

Background technique

At present in a kind of low temperature cigarette on the market, including shell, outer shell outer wall are equipped with display module, if display module includes Dry LED light, is used to indicate charging time, smoking period, preheating unit temperature, air-heating unit temperature etc..Outside due to shell The light that LED light issues on wall is directly transmitted in human eye, thus light seen by person is very uneven, more dazzling, is shown Show that effect is poor, poor user experience.

Utility model content

The purpose of this utility model is that in view of the above shortcomings of the prior art, providing a kind of low temperature cigarette improved, people The display module light homogeneous soft that arrives soon, not dazzling, user experience is good.

In order to solve the above technical problems, the technical scheme adopted by the utility model is:

A kind of low temperature cigarette, including shell and display module, display module include several LED light, are structurally characterized in that display Module further includes the light guide plate in shell, and LED light is set in shell, is opened up on the light guide plate several for installing The light trough of LED light has the light band for stretching out side wall of outer shell on the light guide plate.

Display module be for by low temperature cigarette charge smoke or preheating unit heating or air-heating unit heat when The corresponding information of state be presented to the user and know.So low temperature cigarette is being charged or is being smoked or preheated single by above structure The corresponding information of state when member heating or air-heating unit heat is shown by light band to indicate, so LED light issues Light light is directed to the light band of outer side of shell wall by light guide plate, shown with the bright length of light band, make user more Add the real-time status for getting information about the low temperature cigarette；Simultaneously because the light that LED light issues is conducted by light guide plate, thus people Highly uniform soft to the light on light band soon, not dazzling, user experience is good.

Further, it is equipped between two light troughs adjacent on light guide plate every light slot.

By separating the light that adjacent LED light issues every light slot, optical crosstalk is prevented, light is independent, is equably directed at It is shown in light band, LED light bright light number indicates that real time charging time or smoking period or preheating are single during this display The temperature of member heating or the temperature of air-heating unit heating, conduction of the light of each LED light on light guide plate is independent , so that the excessive homogeneous soft of light of the light of each adjacent two LED light on light band.

Further, it is used to reflect the light that LED light emits to light band at least one on light guide plate Plane of refraction.

At least one plane of refraction is set on light guide plate, and the light for issuing LED light is reflected when encountering plane of refraction, can Light is set more evenly to prevent light from scattering.

The light guide plate is made of PC material as a preferred method,.

The light guide plate is made of PMMA material as a preferred method,.

Compared with prior art, in the utility model, the real-time letter of low temperature cigarette is indicated by the light length of light band Breath, it is more intuitive that information is communicated to user, while by light guide plate conduction light, so light seen by person band light is more Homogeneous soft, not dazzling, user experience is good.
