DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments described in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, top, bottom) in the embodiments of the present utility model are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the term "vertical" involved in the embodiments of the present utility model and the claims means that the angle between the two elements is 90° or there is a deviation of -5° to +5°, and the term "parallel" involved means that the angle between the two elements is 0° or there is a deviation of -5° to +5°.

[0027] In the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0028] In an embodiment of the present application, the combustion device is a device that can burn and emit fragrance, such as an aromatherapy device, and the aromatherapy device can be, for example, a scented candle. The scented candle can emit a pleasant fragrance when burning, and has the effects of purifying the air, soothing nerves, and eliminating odors. In this embodiment, the combustion device with a light detection function is taken as an example of a scented candle with a light detection function.

[0029] See also Figure 1-Figure 5 An embodiment of the utility model provides a combustion device 1 with a light detection function. The combustion device 1 includes, for example: a combustion element 10 and a light detection component 20.

[0030] Specifically, the light detection component 20 is disposed adjacent to the combustion element 10. The light detection component is used to detect the light generated by the combustion element 10 when it is burning. The combustion element 10 may be, for example, a candle body. When the candle body is burning, it will generate a certain amount of light. When the candle body is burned out or blown out by the external environment, it will not generate light. The light detection component 20 of the present application is used to detect in real time whether the combustion element 10 is still burning, thereby avoiding accidents caused by continuous burning of the candle body and improving the safety of the combustion device 1.

[0031] In other embodiments, an early warning module such as a buzzer, an alarm, etc., or a prompt module such as a voice prompt, an LED display, etc. may be provided on the light detection assembly 20. The early warning module or the prompt module can be used to remind the user in real time to prevent safety accidents of the combustion device 1.

[0032] In this embodiment, by setting the light detection component 20 to detect the light generated by the combustion element 10 during combustion, the combustion status of the combustion element 10 can be detected in real time. When the user ignites the combustion device 1, such as a scented candle, when the candle is automatically extinguished, the user can also know that the candle is extinguished through the detection status of the light detection component 20, and the user can immediately light the scented candle again, so that the time for the scented candle to generate fragrance to fill the room will not be prolonged, thereby improving the user experience, and avoiding accidents through the detection status of the light detection component, thereby improving the safety of the combustion device 1.

[0033] like Figure 2-Figure 5 As shown, in a preferred embodiment of the present embodiment, the light detection component 20 includes, for example, a light guide 21 and a light sensor 22 .

[0034] The light guide 21 is arranged corresponding to the light sensor 22, that is, the light guide 21 is arranged vertically in the scented candle, and the light sensor 22 can be arranged on the same plane as the light guide 21, and their positions are relative. The light sensor 22 and the light guide 21 are relative to each other, so that light can be directly transmitted from the light guide 21 to the light sensor 22. The light guide 21 can be made of a combustible material or a hot-melt material. Preferably, the light guide 12 can be made of an acrylic material, for example. The light guide 12 is made of a combustible material or a hot-melt material so that the light guide 12 can be burned and hot-melted together with the candle body when the candle body burns. The flame temperature of the candle body is, for example, 300 degrees. When the candle body is burning, the light guide 12 can also be hot-melted with the burning of the candle body. When the candle body burns in the burning device 1, it will be consumed. For example, after the candle body is consumed, its height in the burning device will decrease accordingly. Since the light guide will be hot-melted by the temperature of the burning candle body, its height in the burning device will also decrease with the burning of the candle body. Furthermore, the light guide 12 can be made of acrylic material. The light guide 12 is made of acrylic material because acrylic has good light-guiding performance and can better transmit the light of the burning part 10 to the light sensor. Secondly, the melting point of acrylic is relatively low, which is lower than the flame temperature of the candle body, that is, the melting point of the light guide 12 made of acrylic material is lower than 300 degrees. When the candle body is burning, the light guide 12 can also be melted by the burning of the candle body.

[0035] like Figure 2-Figure 5 As shown, the light detection component 20 further includes a light shielding member 23 , for example.

[0036] The light shielding member 23 is connected to the light guide member 21 and covers the light sensor 22. The light guide member 21 includes a first light guide surface 211 and a second light guide surface 212, the first light guide surface 211 and the second light guide surface 212 are arranged opposite to each other, the first light guide surface 211 is exposed from the light shielding member 23, and the second light guide surface 212 is located inside the light shielding member 23, that is, one end of the light guide member 21 is exposed from the light shielding member 23, and the other end is arranged inside the light shielding member 23. When the light of the burning member 10 enters from the first light guide surface 211 of the light guide member 21, it is then transmitted to the second light guide surface through the internal action of the light guide member, and then transmitted to the light sensor 22. The efficiency of light in straight line propagation is the highest, so the light guide member 21 and the light sensor 22 are arranged correspondingly, so that the light transmitted by the first light guide surface 211 and the second light guide surface 212 of the light guide member can be transmitted to the light sensor 22 through straight line propagation, so that the detection result of the light sensor 22 is more accurate. The light shielding member 23 is provided to prevent the light sensor 22 from receiving external ambient light, so as to ensure that the light sensor 22 only receives the light emitted by the combustion member 21, thereby improving the accuracy of the detection result of the light sensor 22. The light shielding member 23 is made of an opaque material.

[0037] In a preferred embodiment of this embodiment, if Figure 2-Figure 5 As shown, the light guide 12 may be a straight columnar light guide, and the center points of the first light guide surface 211 and the second light guide surface 212 are located on the same straight line. The present application is set in this way because the straight-line propagation efficiency of light is the highest, so the light guide 21 is set in a straight columnar shape, so that the light generated by the combustion element 11 can be directly transmitted from the first light guide surface 211 to the second light guide surface 212, and then directly transmitted to the light sensor 22 corresponding to the light guide 21, so that the light received by the light sensor 22 is more accurate, thereby improving the efficiency and accuracy of light detection.

[0038] Furthermore, if Figure 4As shown, the light guide 21 further includes a first end 213 and a second end 214, the first light guide surface 211 is arranged on the first end 213, the second light guide surface 212 is arranged on the second end 214, the first end 213 passes through the light shielding member 23, and a part of the structure of the second end 214 is located in the light shielding member 23 so that the second light guide surface 212 is located in the light shielding member 23. The area of ​​the first light guide surface 211 is smaller than the area of ​​the second light guide surface 212. By such a configuration, when the light guide 21 passes through the light shielding member 23, since the area of ​​the second light guide surface 212 is larger than the area of ​​the first light guide surface 211, the second light guide surface 212 cannot pass through the light shielding member 23, so that the light shielding member 23 can not only shield the external ambient light, but also realize the function of fixing the light guide 21, and can realize the configuration of the light guide 21 corresponding to the light sensor 22.

[0039] like Figure 1-Figure 3 As shown, the combustion device 1 further includes, for example, a circuit board 30 , wherein the circuit board 30 is electrically connected to the light sensor 22 ; and the circuit board 30 is connected to the light shielding member 23 . The light shielding member 23 may be fixed on the circuit board 30 .

[0040] like Figure 2-Figure 3 As shown, the combustion element 10 may include, for example, a combustion agent 11, and the combustion agent 11 may cover the light guide 21 and / or the light sensor 22. Of course, in other embodiments, part of the light guide 21 may also be exposed on the surface of the combustion agent 11. The light guide 21 may be partially exposed on the surface of the combustion agent 11, or may be completely inside the combustion agent 11 according to actual conditions, which is not limited here. In this embodiment, the combustion agent 11 is an aromatherapy product that can emit fragrance after burning, which may be, for example, a solid aromatherapy candle body, or a liquid aromatherapy solution, etc., which is not limited here.

[0041] like Figure 2-Figure 3As shown, the combustion member 10 may also include, for example, an ignition member 12, and the ignition member 12 may be arranged in the combustion agent 11, or may be partially exposed on the surface of the combustion agent 11. The ignition member 12 is, for example, a cotton thread candle wick, an electrode portion, etc. In this embodiment, the light guide 21 and the ignition member 12 are vertically arranged in the combustion agent 11, that is, the ignition member 12 and the light guide 21 are both vertically arranged in the combustion agent 11 or vertically arranged and partially exposed on the surface of the combustion agent 11. The height of the light guide 21 decreases as the height of the ignition member 12 decreases, that is, when the ignition member 12 burns, the ignition member 12 will be consumed with the combustion, and the light guide 21 may also be consumed with the consumption of the ignition member 12, and the height is reduced. In other embodiments, the light guide 21 and the igniter 12 may not be vertically arranged in the combustion agent 11, that is, they may be inclined or bent. It is only necessary to meet the purpose that the height of the light guide 21 decreases as the height of the igniter 12 decreases. It can be placed in different ways according to actual conditions, and the specifics are not limited here. The igniter 12 in the present application will generate flames when burning. The combustion agent 11 is, for example, a candle paste. When the igniter 12 generates flames, it will drive the candle paste to be consumed together, and the light at this time is the light obtained by the flame generated by the igniter 11. When the igniter 12 is ignited and consumed in the combustion device 1, its height in the combustion device will also decrease as the flame burns and is consumed. Since the light guide 21 is made of acrylic material, it will also melt as the igniter 12 burns and is consumed. The manifestation of the hot melting of the light guide 21 is that the height of the light guide is also reduced. Therefore, the height of the light guide 21 will decrease as the height of the ignition piece 12 decreases when it burns. In addition, if the height of the light guide 21 does not decrease, it will be exposed to the external ambient light, which will affect the detection result of the light detection component. In the present application, the light detection component 20 detects the light generated by the burning piece 10. When the flame of the ignition piece 12 burns, light can be generated. Therefore, the light detection component 20 detects the flame brightness of the ignition piece 12. If the light guide 21 is not consumed as the ignition piece 12 is consumed, the light detected by the light guide 21 may not be the light generated by the ignition piece 12, so the purpose of detecting the light generated by the ignition piece will be impossible. In addition, when the light guide 21 is consumed as the ignition piece 12 burns, the first light guide surface 211 on the light guide 21 will also be regenerated, and the height of the generated first light guide surface 211 will not exceed the current height of the ignition piece 12.

[0042] In a preferred embodiment of the present embodiment, the light guide 21 can be arranged close to the ignition member 12, or the light guide 21 can be arranged on the ignition member 12. Further, the distance between the light guide 21 and the ignition member 12 is 0-30 mm. The combustion device 1 also includes a circuit board 30, the combustion agent 11 can cover the circuit board 30, and the circuit board 30 is connected to the ignition member 12 and the light guide 21 and is arranged vertically. In this embodiment, the combustible 11 may be, for example, candle paste, that is, the combustible 11 is a paste-like solid, which is covered on the circuit board 30, and then the paste-like solid is stacked layer by layer to a certain height to form a combustible 11 with a certain height, and the igniter 12 is used to burn and can adsorb the candle paste, thereby consuming the candle paste. Since the candle paste will be consumed after being adsorbed, and then the height of the candle paste will be reduced, in order to facilitate the consumption of the candle paste and the effect of linear propagation of light, the igniter 12 and the light guide 21 are both vertically arranged on the circuit board 30. Secondly, in order to facilitate the consumption of the candle paste, the height of the igniter 12 and the light guide 21 are slightly higher than the candle paste, so that the igniter 12 and the light guide 21 are partially exposed from the surface of the candle paste. Secondly, in order to facilitate the simultaneous consumption of the light guide 21 and the ignition piece 12, the distance between the light guide 21 and the ignition piece 12 is set in the range of 0-30mm. This is because the flame generated by the ignition piece 12 during combustion also has a certain radius, such as 10mm. In this way, when the ignition piece 12 is burned and consumed, the acrylic light guide 21 can be melted and consumed by the flame temperature at the same time, so that the ignition piece 12, the light guide 21 and the candle paste can be consumed synchronously, which is further manifested in the specific combustion device 1 as the height of the ignition piece 12, the light guide 21 and the candle paste is reduced synchronously. Therefore, the gap is set here and the circuit board 30 is connected to the ignition piece 12 and the light guide 21 and is set vertically in order to facilitate the simultaneous consumption of the ignition piece 12, the light guide 21 and the candle paste, and to ensure that the light detection component 20 in the combustion device 1 can always detect the light of the ignition piece 12, and will not detect the light of other external ambient light, to prevent interference from the outside.

[0043] In addition, it can be understood that the aforementioned embodiments are merely illustrative descriptions of the present invention. Under the premise that the technical features do not conflict, the structures do not contradict, and the purpose of the present invention is not violated, the technical solutions of the various embodiments can be arbitrarily combined and used in combination.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
