Description

Technical Field

[0001] The invention belongs to the field of low-temperature cigarettes, and in particular relates to a low-temperature smoking device with light display. Background Art

[0002] Traditional cigarettes need to be lit with an open flame to produce tobacco smoke. During the high temperature and cracking process, tobacco releases thousands of mixed substances that are harmful to the human body, which are composed of volatile substances in the gas and semi-volatile and non-volatile substances in the particles, such as carbon monoxide, phenols, aldehydes, nicotine (nicotine), tar, etc., while heat-not-burn low-temperature smoking devices can effectively reduce the production of harmful substances and are healthier. Currently, there are two types of low-temperature smoking devices on the market: center heating and surrounding heating. Both use batteries to provide energy to the heating element to heat the low-temperature cigarette to the set temperature and produce smoke for users to inhale.

[0003] Most low-temperature smoking devices use rechargeable lithium batteries to power the heating element. When the low-temperature smoking device is used for a period of time and the battery is exhausted, the user can charge it and continue to use it after it is fully charged. Usually, when the low-temperature smoking device is used, the heating time for each cigarette is fixed (pre-set by the system). After smoking a cigarette, it is generally necessary to restart the heating program and then smoke the second cigarette; when the battery is fully charged, it can generally smoke more than a dozen cigarettes before it needs to be recharged. However, consumers usually do not remember how many cigarettes they have smoked, so it is difficult for them to accurately grasp the charging time of the smoking device.

[0004] Chinese patent application number 201320635746.0 discloses an electronic cigarette with a battery display device, and Chinese patent application number 201420622436.X discloses a power supply device and an electronic cigarette. Both electronic cigarettes are provided with a plurality of LED lights or indicator lights for displaying the battery level. The battery level is displayed by the brightness of the LED lights or indicator lights. However, the direct projection of the LED lights on the outer surface of the smoking device is likely to cause glare, affecting the user experience. Summary of the invention

[0005] The technical problem solved by the present invention is: to provide a low-temperature smoking device with light display in view of the above-mentioned deficiencies in the power display of the existing low-temperature smoking device.

[0006] The present invention is implemented by the following technical solutions:

[0007] A low-temperature smoking device with light display, wherein the low-temperature smoking device is provided with a light-emitting unit 2, wherein the light-emitting unit 2 comprises a plurality of light sources 81 electrically connected to an electric control unit of the low-temperature smoking device, and a light guide plate 21 for transmitting light emitted by the light sources 81 to a specific direction;

[0008] One end face of the light guide plate 21 is close to the light source 81, and the other end face extends to the shell 1 of the low-temperature smoking device. The above two end faces are both light-transmitting surfaces. The side face of the light guide plate 21 is a reflective surface 212, and a plurality of protruding or recessed reflective points 215 are arranged on the reflective surface 212. Part or all of the light emitted by the light source 81 is reflected by the reflective surface 212 and its reflective points 215 and propagates along the inside of the light guide plate 21, and is displayed as a continuous light band on the shell 1 of the low-temperature smoking device.

[0009] Furthermore, the reflective surface 212 is arranged along the arrangement direction of the light sources 81 .

[0010] Furthermore, the reflective surface 212 is a continuous plane, and the light-transmitting surfaces of the two sections of the light guide plate 21 are located at two ends of the continuous plane.

[0011] Furthermore, the electronic control unit is a PCB board, the light source 81 is a plurality of LED lamps arranged on the PCB board, and the LED lamps are directly electrically connected to the circuit printed on the PCB board.

[0012] Furthermore, a lamp groove 213 corresponding to each light source 81 is disposed on one end surface of the light guide plate 21 , and the end surface of the light guide plate 21 covers and connects all the light sources 81 through the lamp groove 213 .

[0013] Furthermore, a positioning arm 211 is provided on the light guide plate 21 , and the light guide plate 21 is fixed on the PCB board through the positioning arm 211 .

[0014] Furthermore, the reflective point 215 is a spherical protrusion or a spherical groove with a spherical arc surface.

[0015] Furthermore, the size of the light reflecting spot 215 gradually decreases in the direction away from the light source 81 .

[0016] Furthermore, a light-transmitting belt 22 is provided on the housing 1 to cover the light-transmitting surface of the light guide plate 21 .

[0017] In the low-temperature smoking device with light display of the present invention, the light guide plate 21 is made of a light-transmitting material as a whole, a reflective layer is arranged on the surface of the light guide plate 21 corresponding to the reflective surface 212, and the reflective point 215 is arranged on the surface of the light guide plate 21 inside the reflective layer.

[0018] The present invention sets a light-emitting unit on the low-temperature smoking device. The light-emitting unit uses an LED lamp controlled by a PCB board as a light source. The light emitted is transmitted through a light guide plate and then displayed as a light band on the shell of the low-temperature smoking device. The light is reflected by a reflective surface on the light guide plate to ensure that all the light emitted by the light source is transmitted inside the light guide plate, which can ensure that most of the light emitted by the light source is emitted through the light guide plate. At the same time, a number of convex or concave reflective points are set on the reflective surface, and the spherical surface is used to reflect the light to make the final light brightness softer. Due to the setting of the reflective surface and the reflective point, it is not necessary to place the light source close to the shell of the smoking device for direct light emission, which avoids the reduction of the user's experience due to excessive light emission, and the position of the PCB board inside the shell can be reasonably designed, and there is no need to specially set a position close to the shell for the light source.

[0019] The light-emitting unit of the present invention can be used to display the power level and working status of the low-temperature smoking device, so that the user can intuitively know the battery usage of the low-temperature smoking device or the usage status of the electronic smoking device. It can also be a simple light-emitting effect display to improve the appearance of the electronic smoking device.

DETAILED DESCRIPTION

[0028] Example

[0029] See also Figure 1 and Figure 2 The low-temperature smoking device shown in the figure is a preferred embodiment of the present invention, and includes a housing 1 and a light-emitting unit 2 arranged on the housing 1. The housing 1 is the entire body shell of the low-temperature smoking device. The housing 1 in this embodiment is divided into a front housing and a rear housing, which are buckled together to form a complete housing 1; a key switch 3 is provided on the housing 1, and the key switch 3 is electrically connected to a PCB board 8 inside the housing 1. The PCB board 8, as an electric control unit of the low-temperature smoking device, can control the start and stop of the low-temperature smoking device; a cigarette insertion port 4 is provided on the top cover of the housing 1. When in use, a cigarette is inserted from the cigarette insertion port 4 into a heating element 6 fixed inside the low-temperature smoking device. The heating element 6 is controlled to start and stop by the PCB board 8 and the key switch 3, and the inserted cigarette is heated without burning to generate smoke for the user to inhale. The heating element 6 is provided with a heat insulation layer 7 on the outside to prevent the heat of the heating element 6 from being transferred outward; a battery 9 is also provided inside the housing 1, and the battery 9 provides electric energy to the heating element 6 through the control of the PCB board 8, and converts the electric energy into heat energy to heat the cigarette. A sliding cover 5 is provided outside the housing 1 near the cigarette insertion port 4. The cigarette insertion port can be opened or closed by pushing the sliding cover 5.

[0030] The above is the basic structure of the low-temperature smoking device. The structural features of each component and the circuit control scheme can refer to the existing low-temperature smoking devices, and this embodiment will not be described in detail here.

[0031] The light emitting unit 2 is disposed on the housing 1 to display the power level, working status and other signals of the low-temperature smoking device through light. This embodiment is described in detail by taking the light emitting unit 2 displaying the power level of the battery 9 of the low-temperature smoking device as an example.

[0032] Combination Figure 3 The light-emitting unit 2 specifically includes a light guide plate 21, a light-transmitting belt 22, and a plurality of light sources 81. In this embodiment, a plurality of LED lamp beads are used as the light source 81. All the LED lamp beads are arranged in a straight line on the PCB board 8 and are electrically connected to the PCB board 8. The light source 81 is powered on and illuminated by the power detection circuit printed on the PCB board 8. The LED lamp beads used as the light source 81 are directly arranged in a row and integrated and fixed on the PCB board 8. At the same time, the battery power detection circuit is a common technology. In this embodiment, the power detection circuit of the light source 81 is not described in detail. The light guide plate 21 is fixed inside the shell 1 of the low-temperature smoking device, one end of which is close to the light source and the other end extends to the surface of the shell 1 of the low-temperature smoking device, so that the light emitted by the light source 81 is transmitted to the surface of the shell 1.

[0033] Since the light emitted by the light source 81 is in a scattered state, in order to ensure that most of the light can be transmitted and extended inside the light guide plate 21, the light emitted by the light source 81 is transmitted from the inside of the shell 1 to the shell 1 for display. In this embodiment, the side surface connecting the two end surfaces of the light guide plate 21 is set as a reflective surface 212, and the reflective surface 212 is a continuous, smooth and flat plane. The two end surfaces of the light guide plate 21 are transparent surfaces. In this way, after the light emitted by the light source 81 enters the light guide plate 21 from any direction, part of the light parallel to the reflective surface 212 directly passes through the light guide plate 21, and the other part of the light entering the light guide plate 21 at a certain angle is reflected by the reflective surface 212 and finally most of the light can be emitted from the light guide plate 21 to the transparent end surface 214 extending from the shell to the shell, and displayed as a continuous light band on the shell 1 of the low-temperature smoking device.

[0034] Specific as Figure 4 and Figure 5 As shown, in order to make the brightness of the light band displayed on the shell 1 softer, the present embodiment arranges a plurality of reflective points 215 on the reflective surface 212. The reflective points 215 are protruding structures or recessed structures arranged on the reflective surface 212. The setting of the reflective points 215 upgrades the reflection effect of the reflective surface 212 on the light from mirror reflection to diffuse reflection. The multiple reflective points 215 densely distributed thereon adjust the angle of the disordered light for multiple consecutive times, and finally emit them uniformly from the light-transmitting end surface 214 of the light guide plate 21. The reflective points 215 adjust the angle of the light, thereby ensuring that the brightness of the light band of the final light-emitting unit 2 is softer.

[0035] A plurality of lamp slots 213 are processed on the end surface of the light guide plate 21 located on the inner side of the housing 1. The number and position of the lamp slots 213 match the LED lamp beads of the light source 81. The end surface of the light guide plate 21 can cover and dock with all the light sources 81 through the lamp slots 213. At the same time, through the focusing effect of the lamp slots 213, it can further ensure that the light of the light source 81 enters the interior of the light guide plate 21. The reflective surface 212 on the light guide plate 21 is arranged along the arrangement direction of the light source 81, and is connected between the light-transmitting surfaces at both ends of the light guide plate 21 to form a complete flat plane. The overall structure of the light guide plate 21 is made of translucent material, and a reflective layer is set on the surface of the reflective surface 212 by gluing or coating, and only the two end surfaces close to the light source and the shell are reserved as translucent end surfaces. The reflective point 215 is directly processed on the surface of the light guide plate 21 corresponding to the reflective surface 212, and then the reflective layer is arranged to ensure that the reflecting surface of the reflective point 215 is on the inner side of the reflective layer. In this way, part of the light emitted by the light source 81 is directly transmitted inside the light guide plate 21, and the other part is reflected multiple times by the reflective surface 212 and the reflective points 215 set thereon, and can all be emitted from the translucent end surface 214 close to the shell. Compared with direct light, the emitted light is softer and less dazzling.

[0036] See also Figure 6 The reflective point 215 in this embodiment adopts a spherical protrusion or a spherical groove with a spherical arc surface, and the size of the reflective point 215 gradually decreases along the direction away from the light source. This is because the intensity of the light emitted by the light source will gradually change with the change of the propagation distance, and the smaller the diameter of the spherical surface, the higher the intensity of the reflected light. In this embodiment, by reasonably arranging reflective points 215 of different sizes on the reflective surface 212, the intensity of light transmitted by the light guide plate 21 is more balanced.

[0037] In this embodiment, the light of the light source 81 disposed inside the shell is conducted through the light guide plate 21, so the light source 81 does not need to be disposed close to the shell of the low-temperature smoking device or facing the shell of the low-temperature smoking device, and can be disposed in a direction facing the inside of the shell or parallel to the inner wall of the shell, which is more conducive to the arrangement of the PCB board 8 in the shell inside the low-temperature smoking device. Two sets of positioning arms 211 are disposed on both ends of the end surface of the light guide plate 21 close to the light source 81. The positioning arms 211 are processed with connection holes, and the positioning arms 211 and the light guide plate 21 can be fixed to the PCB board 8 by screws and other connecting parts. The lamp groove 213 disposed on the end surface covers all the LED lamp beads, so that the light emitted by the LED lamp is gathered by the lamp groove 213, and then guided by the light guide plate 21, and then emitted from the light-transmitting end surface 214 of the light guide plate 21.

[0038] An empty groove corresponding to the light-transmitting end face 214 of the light guide plate 21 is processed on the shell 1 of the low-temperature smoking device. The light-transmitting end face 214 guides the light out through the empty groove. The light-transmitting end face 214 of the light guide plate 21 is close to the inner side of the empty groove. A light-transmitting belt 22 is fixedly covered on the empty groove and closely attached to the light-transmitting end face 214. The light-transmitting belt 22 can also emit the light guided by the light guide plate 21 from the LED lamp groove, further softening the bright band formed on the surface of the shell 1, and can form the shell 1 of the low-temperature smoking device into a complete protective shell.

[0039] Through the power detection circuit on the PCB board 8, the number, time, brightness, color, etc. of the LED lamp beads of the light source 81 are controlled, and the battery power or discharge amount is matched with the lighting condition of the LED lamp, so that the LED lamp can display the battery power, allowing the user to intuitively know the battery usage of the low-temperature smoking device, and also improving the appearance quality and value of the low-temperature smoking device.

[0040] In practical applications, the light-emitting unit 2 can also be used as a working status display of the low-temperature smoking device or a simple light-emitting effect display, such as a breathing light effect during the inhalation process, which is realized through a corresponding control circuit, and this embodiment will not be described in detail here.
