Technical Field

[0001] The utility model relates to the technical field of candles, in particular to a candle extinguishing structure and a candle. Background Art

[0002] As a traditional and common lighting tool and decoration, candles are widely used in various fields and occasions. People like to light candles in scenes such as family gatherings, romantic dates, yoga meditation, etc. to create a warm and romantic atmosphere. However, with people's pursuit of relaxation, soothing and improving the quality of life, the emergence of scented candles has brought new possibilities for the application of candles. Scented candles can not only provide lighting and decoration functions, but also bring pleasant fragrance to the space by releasing aromatic fragrance, creating a more comfortable and relaxing environment. Scented candles have been widely used and welcomed in homes, offices, bathing places and other places. In the existing scented candle market, the common scented candles are essential oil candles, which release aromatic fragrance when burning.

In the following description, the expression "some embodiments" is involved, which describes a subset of all possible embodiments, but it should be understood that "some embodiments" can be the same subset or different subsets of all possible embodiments, and can be combined with each other without conflict.

[0041] It should also be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "inside", "outside", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation method.

[0042] Please refer to the attached Figure 1 and 2 , an embodiment of the utility model provides a candle extinguishing structure, including an air guide structure 11 arranged in the direction of air flow; the air guide structure 11 includes an air guide shell 111, an air inlet 112 and an air outlet 113 arranged on the air guide shell 111; the air inlet 112 is located on the side of the air guide shell 111 facing the air flow direction, and the air outlet 113 is arranged corresponding to the candle. It should be further explained that the air guide shell 111 is in an arc shape and can be designed according to the principles of fluid mechanics, aiming to provide a smooth guiding surface, so that the air flow can flow more smoothly in the air guide shell 111, reducing the resistance of the air flow and the generation of turbulence. The air outlet 113 can be arranged toward the candle wick 31 to extinguish the candle more quickly.

[0043] In this embodiment, an air guide structure 11 is arranged inside the candle. By using the air guide structure 11, the air flow can be guided to the surrounding of the candle, and the candle can be extinguished under the premise of safety. Compared with the traditional candle extinguisher, the candle extinguishing structure provided in this embodiment is safer, more convenient and easier to use. The reason is that the traditional candle extinguisher needs to be manually placed above the candle to block the supply of oxygen to extinguish the candle, which poses a safety hazard.

[0044] In an optional embodiment, the port area of ​​the air inlet 112 is larger than the port area of ​​the air outlet 113. The port area of ​​the air inlet 112 refers to the cross-sectional area of ​​the opening of the air inlet 112, and the port area of ​​the air outlet 113 refers to the cross-sectional area of ​​the opening of the air outlet 113. By setting the port area of ​​the air inlet 112 larger than the port area of ​​the air outlet 113, a better accumulation effect is achieved for the airflow, forming a stronger airflow to extinguish the corresponding candle.

[0045] In an optional embodiment, a chamber is formed in the air guide shell 111, and a side wall of the port of the air inlet 112 is extended toward a side away from the chamber to form an air guide plate 114, which is arc-shaped and bends in the direction of the air flow inflow. The chamber with a certain volume formed in the air guide shell 111 can first converge the air flow in from the air inlet 112, increase the pressure difference between the air outlet 113 and the air outlet 113, thereby increasing the speed of the air flow out of the air outlet 113; by arranging the air guide plate 114 on the side wall of the port of the air inlet 112, the air guide plate 114 is arc-shaped and bends in the direction of the air flow inflow, which can effectively guide the flow direction of the air flow, so that the air flow enters the air inlet 112 and flows to the air outlet 113 more smoothly.

[0046] In an optional embodiment, a partition 115 is provided in the air guide shell 111, and the partition 115 divides the space in the air guide shell 111 into a plurality of sub-chambers; the plurality of sub-chambers include at least one exhaust chamber 1111 and one muffler chamber 1112; the air outlet 113 is provided corresponding to the exhaust chamber 1111 and is connected to the exhaust chamber 1111. It should be further explained that by providing the partition 115, the turbulence formed by the air flow can be reduced, so that the air flow can be better guided to the surrounding of the candle along the air outlet 113. The muffler chamber 1112 is provided corresponding to the exhaust chamber 1111 and is connected to the exhaust chamber 1111, and the muffler chamber 1112 is used to absorb the noise generated by the exhaust chamber 1111. In the exhaust chamber 1111, due to the flow of the air flow, the air flow will collide with the partition 115 and the cavity wall of the exhaust chamber 1111, generating noise, which affects the user's experience of using the candle. The number of the partitions 115 can be set according to specific design requirements, space requirements, functional requirements, etc., and can be one or more.

[0047] In an optional embodiment, the partition 115 divides the space inside the air guide shell 111 into an exhaust chamber 1111 and a muffle chamber 1112, and the volume of the exhaust chamber 1111 is greater than the volume of the muffle chamber 1112. It should be further explained that the ratio of the volume of the exhaust chamber 1111 to the volume of the muffle chamber 1112 is greater than 2:1. The air inlet 112 is arranged on the side of the exhaust chamber 1111 facing the airflow direction, and the air outlet 113 is arranged on the side of the cavity wall of the exhaust chamber 1111 away from the air inlet 112, and the partition 115 extends from the position of the air inlet 112 to the cavity wall of the cavity in the air guide shell 111. The volume of the exhaust chamber 1111 gradually decreases from the air inlet 112 to the direction of the air outlet 113. The air inlet direction of the air inlet 112 and the air outlet direction of the air outlet 113 can be different, so as to guide the airflow around the candle.

[0048] In an optional embodiment, the end of the partition 115 close to the air inlet 112 is a diverter end 1151, and the end surface of the diverter end 1151 is lower than the end surface of the air inlet 112 so that the silencing chamber 1112 and the exhaust chamber 1111 are connected, or a gap is formed between the end surface of the diverter end 1151 and the end surface of the air inlet 112, and the silencing chamber 1112 and the exhaust chamber 1111 are connected through the gap. The connection between the exhaust chamber 1111 and the silencing chamber 1112 located in front of the diverter end 1151 at the air inlet 112 can reduce the noise generated when the airflow enters the air guide shell 111 and is diverted at the air inlet 112 to enter the silencing chamber 1112 and the exhaust chamber 1111, and the silencing chamber 1112 can reduce the propagation and reflection of sound waves, thereby achieving the effect of silencing and noise reduction.

[0049] Please refer to the attached Figure 3 Another embodiment of the utility model provides a candle, comprising a base 20, a candle holder 30 provided with a candle wick 31, and a candle extinguishing structure of any one of the above embodiments, wherein the candle holder 30 is installed on the top of the base 20, and the candle extinguishing structure is fixed in the base 20. Among them, the base 20 provides a support platform for the candle holder 30 on the one hand, and is used to accommodate the candle extinguishing device on the other hand. The candle extinguishing structure and the base 20 can be fastened by bolts. Optionally, a switch button for controlling the candle extinguishing structure is provided on the base 20. When the user wants to extinguish the candle, the user can touch or press the switch button of the candle extinguishing structure to extinguish the candle. The base 20 and the candle holder 30 can adopt a split structure or an integrated structure. The split structure refers to dividing the base 20 and the candle holder 30 into two independent parts, which are manufactured and assembled separately, so as to facilitate the manufacture and replacement of the base 20 or the candle holder 30. The integrated structure means that the base 20 and the candle holder 30 are designed as an integral part, which reduces the connection and assembly process between parts, improves the sealing performance, and reduces the loss of airflow.

[0050] Please refer to the attached Figure 4and 5 The candle extinguishing structure also includes a fan assembly 12 disposed at the air inlet 112 of the air guide housing 111. The fan assembly 12 includes a fan housing 121 and a fan 122 disposed in the fan housing 121. The air outlet 123 of the fan housing 121 is connected to the air inlet 112 of the air guide housing 111, and the air outlet 113 of the air guide housing 111 is connected to the candle holder 30. The airflow generated by the fan 122 flows through the air inlet 112, the air guide housing 111, and the air outlet 113 in sequence, and then flows to the inside of the candle holder 30 to achieve the effect of extinguishing the candle. In a specific example, the air outlet 123 of the fan housing 121 is connected to the air inlet 112 corresponding to the exhaust chamber 1111, and the air outlet 113 corresponding to the exhaust chamber 1111 is connected to the candle holder 30. It can be explained that the airflow generated by the fan 122 basically all enters the exhaust chamber 1111, and under the extrusion of the exhaust chamber 1111, it flows from the air outlet 113 to the candle holder 30 to extinguish the candle wick 31 in the candle holder 30. The side of the air guide shell 111 on which the air inlet 112 is provided is the air inlet end 124 surface, and the side of the fan shell 121 on which the air outlet end 123 is provided is the air outlet end 123 surface. The shapes and sizes of the air inlet end 124 surface and the air outlet end 123 surface can match each other to ensure that the air guide shell 111 and the air outlet shell are tightly connected, reduce the leakage of the air flow, and achieve good air flow guidance. Exemplarily, the air inlet end 124 surface is rectangular, and the air outlet end 123 surface is also rectangular. The fan 122 can be a centrifugal fan, which can generate a higher airflow pressure and has low noise.

[0051] Please refer to the attached Figure 6 The base 20 includes a shell 21 and a cover plate 22 mounted on the shell 21. The shell 21 and the cover plate 22 are assembled to form a receiving chamber. The candle extinguishing structure is placed in the receiving chamber. A through hole 221 is opened at a position of the cover plate 22 corresponding to the air outlet 113. The air outlet 113 can extend into the candle holder 30 through the through hole 221, or can be connected to the through hole 221, so that the air outlet 113 and the candle holder 30 are connected through the through hole 221. The candle extinguishing structure can also include a control panel 13. A control circuit is correspondingly arranged on the control panel 13. An operation button 14 connected to the control circuit is arranged on the side wall of the shell 21. The user can input an operation instruction through the operation button 14 to open or close the candle extinguishing structure or adjust the airflow rate.

[0052] The fan housing 121 is provided with an air inlet end 124, which can be arranged directly opposite to the fan 122, and is used to guide the external airflow into the fan 122. The candle provided in this embodiment has the technical effect of the candle extinguishing structure, which is not described in detail here. The candle provided in this embodiment can be an aromatherapy candle. An aromatherapy candle is a special type of candle that releases a fragrant aroma when burned. The use of aromatherapy candles can help purify the air, improve the atmosphere, relieve stress and anxiety, and can also be used to provide relaxation, soothing and sleep effects.

[0053] In an optional embodiment, the air guide housing 111 is provided with a first connecting member 1113 at a position close to the air inlet 112, and the fan housing 121 is provided with a second connecting member 1211 at a position close to the air outlet 123, and the air guide housing 111 is fastened to the fan housing 121 through the first connecting member 1113 and the second connecting member 1211. Specifically, the first connecting member 1113 is provided on both sides of the air inlet end 124 surface, and the second connecting member 1211 is provided on both sides of the air outlet end 123 surface and at a position corresponding to the first connecting member 1113. The air guide housing 111 and the fan housing 121 are detachably connected through the first connecting member 1113 and the second connecting member 1211. The outer periphery of the fan housing 121 is provided with screw holes 1212, and the fan housing 121 is fastened to the base 20 by means of bolts passing through the screw holes 1212.

[0054] In a specific example, the first connecting member 1113 is a card block, the second connecting member 1211 is a card slot, and the air guide housing 111 is fastened to the fan housing 121 by means of the card block and the card slot being engaged. The shape and size of the card slot match the card block to ensure that the card block can be inserted into the card slot and provide a fixed connection. In another specific example, the first connecting member 1113 and the second connecting member 1211 are both magnetic members, and the air guide housing 111 is connected to the fan housing 121 by the mutual magnetic attraction of the first connecting member 1113 and the second connecting member 1211, and this connection method is convenient for installation and disassembly.

[0055] Please refer to the attached Figure 7 and 8In an optional embodiment, the fan housing 121 includes a volute 1213 and a volute tongue 1214, the volute tongue 1214 is in a gradually opening arrangement, and an air outlet end 123 is formed at the end of the volute tongue 1214; an air guide plate 114 is formed on the port side wall of the air inlet 112 extending toward the side away from the chamber, and the air guide plate 114 is inserted from the air outlet end 123 and abuts against the inner wall of the volute tongue 1214. It can be explained that the gradually opening arrangement of the volute tongue 1214 means that the volute tongue 1214 gradually moves away from the volute 1213, so that the air outlet duct formed by the volute 1213 and the volute tongue 1214 gradually widens, and a larger air outlet end 123 matching the air inlet 112 on the air guide housing 111 is formed at the end of the duct structure. The air guide plate 114 arranged at the port of the air inlet 112 of the air guide shell 111 can, on the one hand, guide the airflow of the air outlet duct of the fan 122 so that the airflow flowing out of the fan 122 enters the air guide shell 111 along the air inlet 112 as much as possible to avoid airflow loss. On the other hand, the abutment arrangement of the air guide plate 114 and the volute tongue 1214 can make the connection between the air guide shell 111 and the fan shell 121 more secure.

[0056] In an optional embodiment, the air guide plate 114 is an arc-shaped air guide plate, and the joint between the arc-shaped air guide plate and the volute tongue 1214 is an arc curve. It should be further explained that the shape of the arc-shaped air guide plate is designed according to the principles of fluid mechanics, aiming to minimize the resistance of the airflow and better achieve the air guiding effect. In addition, by designing the joint between the arc-shaped air guide plate and the volute tongue 1214 as an arc curve, a smooth transition of the airflow can be achieved, and the separation of the airflow at the joint can be avoided.

[0057] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited to them. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
