CROSS REFERENCE TO RELATED APPLICATIONS

The present application claims the benefit of Chinese Utility Model Application Nos. 202320113219.7 filed on Feb. 4, 2023 and 202320107000.6 filed on Feb. 3, 2023. All the above are hereby incorporated by reference in their entirety.

TECHNICAL FIELD

The present disclosure relates to the field of automatic extinguishing products for an aromatherapy product and a candle, and specifically, to an automatic extinguisher.

BACKGROUND

A candle automatically goes out only when it is completely burned out in a burning process. If the candle needs to be extinguished before it is completely burned out, it needs to be manually extinguished, which is quite troublesome. The candle cannot be automatically controlled to go out at specific time. In offices, houses, churches, and other occasions, an aromatherapy product is often ignited to create a comfortable and pleasant atmosphere. During burning of the aromatherapy product, a pleasant aroma is generated, achieving a refreshing and tranquil effect and giving people a comfortable feeling. After the aromatherapy product is ignited, it automatically goes out only when it is completely burned out. If the aromatherapy product needs to be extinguished in a burning process, it needs to be manually extinguished. Therefore, it is impossible to set automatic extinguishing time for the aromatherapy product and the candle in the burning process. For example, it is often unnecessary to wait for the aromatherapy product to burn out and go out automatically. The aromatherapy product can be manually extinguished after being ignited and burned for a certain period of time, thereby fragrance will linger indoors for a long time. It is troublesome to manually extinguish the aromatherapy product or the candle.

SUMMARY

For a candle, an aromatherapy product, and the like for which automatic extinguishing time cannot be set in a burning process and that often go out automatically only when being completely burned out, the present disclosure provides an automatic extinguisher, thereby burning time of the candle and the aromatherapy product can be automatically controlled through setting, and the candle and the aromatherapy product can be controlled to go out at a set time point through setting based on a usage demand and do not need to be manually extinguished, achieving more convenient use.

Technical solutions adopted to resolve the technical problems in the present disclosure are as follows: An automatic extinguisher includes a base, a cover, a lifting rope, and a motor, where the base is provided with a support connected to a main body, the main body is provided with the cover connected to the lifting rope, the motor controls release or roll-up of the lifting rope, the release of the lifting rope controls the cover to move downwards to cover an opening of a cup placed below the cover, whereby a burning candle or aromatherapy product inside the cup is extinguished, and responsive to the roll-up of the lifting rope, the cover moves upwards, and the opening of the cup is uncovered.

A shaft of the motor is connected to a rope winding wheel that is wrapped with the lifting rope. One end of the lifting rope is connected to the cover. Responsive to the motor controlling the rope winding wheel to rotate to release the lifting rope, the cover moves downwards due to gravity to cover the opening of the cup placed below the cover.

Responsive to the motor controlling the rope winding wheel to rotate to roll up the lifting rope, the cover is pulled upwards by the lifting rope, and the opening of the cup is uncovered. When the cover moves upwards, it can be hidden in the main body. During next use, a user can directly ignite the candle or the aromatherapy product inside the cup, or take out the cup, ignite the candle or the aromatherapy product inside the cup, and then put the cup back to an upper end face of the base.

The motor and the rope winding wheel are disposed inside the base, and one end of the lifting rope in the rope winding wheel passes through the support which is hollow and is connected to the cover inside the main body. The motor controls the release or the roll-up of the cover through the lifting rope. Alternatively, the motor and the rope winding wheel may be disposed inside the main body, and the lifting rope in the rope winding wheel is connected to the cover.

The base is provided with a circuit, and the circuit is connected to the motor through a wire to control the motor to perform forward or reverse rotation, thereby controlling the release or roll-up of the lifting rope.

During use, when a higher cup needs to be used, there is no need to adjust a release length of the lifting rope. Responsive to the motor controlling the rope winding wheel to rotate to release the lifting rope, after the cover moves downwards to cover the cup placed below the cover, the cover stops moving. When the motor can continue to release the lifting rope, due to flexibility of the lifting rope, the release length of the lifting rope does not need to be adjusted, and the cover remains stationary and covers the opening of the cup, which is suitable for cups of different heights. A gravity ball may also be installed in the lifting rope at an upper end of the cover. After the cover moves downwards to cover the cup placed below the cover, the cover stops moving. When the motor continues to release the lifting rope, the gravity ball continues to pull the lifting rope downwards. When the higher cup needs to be used, there is no need to adjust the release length of the lifting rope, which is suitable for the cups of different heights.

The circuit can set the set time point of the motor, and can control the motor to start to rotate at a set time point, so as to control the cover to cover the opening of the cup at set time.

The circuit can be communicatively connected to a timing remote control, and the set time point of the motor can be set through the timing remote control. Responsive to reaching the set time point, the circuit controls the cover to cover the opening of the cup, thereby the candle or the aromatherapy product inside the cup is extinguished.

The base includes a battery. The battery can provide power to the circuit. Alternatively, a wire of a power interface can be directly used to provide power to the circuit or charge the battery.

The upper end face of the base is provided with a positioning ring that matches a bottom of the cup. The bottom of the cup can be placed in the positioning ring. This makes it convenient to place the cup in a centered manner, and also makes it convenient to more accurately cover the opening of the cup when the cover moves downwards, preventing the cup from being inaccurately covered due to displacement of the cup during use.

An automatic extinguisher includes a base, a main body, a motor, a cover, and a circuit, where an upper end of the base is provided with the main body, an upper end of the main body is provided with the motor connected to the cover, the motor controls extension and retraction of the cover, the motor is connected to the circuit, the motor rotates to control the cover to extend downwards and cover a cup placed on an upper end face of the base, thereby a burning candle or aromatherapy product inside the cup is extinguished due to a lack of oxygen, and the motor rotates reversely to control the cover to retract upwards, thereby the main body of the cup is uncovered. During next use, a user can ignite the candle or the aromatherapy product inside the cup.

The motor is provided with a screw engaged with a nut, the nut is connected to the cover, the motor rotates to control the screw to rotate, and the screw rotates to control the nut and the cover to move.

The cover is slidably matched with a guide post. Responsive to the screw rotating to control the nut and the cover to move, the guide post performs guiding and positioning on the cover to prevent the nut from rotating. A screw thread of the screw pushes the nut to make a linear motion, thereby transforming a rotational motion of the screw into the linear motion of the nut. The cover slides in a straight line in contact with the guide post.

The base is provided with the circuit therein, and the circuit is connected to the motor through a wire to control the motor to perform forward or reverse rotation, thereby controlling the cover to move upwards or downwards.

The circuit can set the set time point of the motor, and can control the motor to start to rotate at the set time point. Through the circuit, the motor can be set to control, after 30 minutes, the cover to extend downwards to cover the opening of the cup placed on the upper end face of the base.

A distance of the downward extension or the upward retraction of the cover can be controlled by a quantity of rotation turns of the motor controlled by the circuit. For example, responsive to the cover extending downwards to the opening of the cup, the circuit controls the motor to rotate reversely for 200 revolutions to retract the cover upwards. When it is necessary to cover the cup, the circuit controls the motor to rotate forward by 200 revolutions, and the cover extends downwards to the opening of the cup, thereby the opening of the cup is covered.

For example, after the candle is ignited, the candle is required to automatically go out only after burning for 30 minutes. Through the circuit, the user can set to automatically extinguish the candle after 30 minutes. After 30 minutes after igniting the candle, the circuit controls the motor to rotate forward by 200 revolutions. After the motor stops rotating, the cover extends downwards to the opening of the cup to cover the opening of the cup. At this moment, the opening of the cup is covered, and the burning candle inside the cup is extinguished due to a lack of oxygen. After the candle is extinguished, the circuit controls the motor to rotate reversely for 200 revolutions to retract the cover upwards to uncover the opening of the cup.

The circuit can be communicatively connected to a timing remote control, and the set time point of the motor can be set through the timing remote control. Responsive to reaching the set time point, the circuit controls the motor to rotate. The motor rotates to control the cover to move downwards to cover the opening of the cup, thereby the candle and the aromatherapy product inside the cup automatically go out.

The base includes a battery. The battery can provide power to the circuit. Alternatively, a wire of a power interface can be directly used to supply power to the circuit. Responsive the power interface of the circuit being connected, the battery can be charged.

The present disclosure has following beneficial effects: 1. The base is provided with the support connected to the main body, and the main body is provided with the cover connected to the lifting rope. The motor controls the release or the roll-up of the lifting rope. The release of the lifting rope controls the cover to move downwards to cover the opening of the cup placed below the cover, thereby the burning candle or aromatherapy product inside the cup is extinguished. Responsive to the roll-up of the lifting rope, the cover moves upwards, and the opening of the cup is uncovered. The motor and the lifting rope are combined to control the release or the roll-up of the cover to extinguish the burning candle or aromatherapy product inside the cup. The extinguishing time of the candle or the aromatherapy in the burning process can be automatically controlled through the setting. In addition, when the higher cup needs to be used, the release length and a roll-up length of the lifting rope do not need to be adjusted, which is suitable for the cups of different heights. It is more convenient and reasonable during use. 2. The upper end of the base is provided with the main body, and the main body is provided with the adjustable cover. The cover is controlled by the motor, and the circuit can control the motor to start to rotate at the set time point. The motor rotates to control the cover to extinguish, at specified time based on the set time, the burning candle or aromatherapy product placed on the upper end face of the base. 3. The extinguishing time of the candle and the aromatherapy product can be automatically controlled in the burning process through the setting, and the user can set to automatically control the candle and the aromatherapy product to go out at the set time point based on a usage demand, and does not need to manually extinguish the candle and the aromatherapy product.

The base 1 is provided with a support 2 connected to the main body 5, and the main body 5 is provided with the cover 6 connected to the lifting rope 7. A motor 9 controls release or roll-up of the lifting rope 7. The release of the lifting rope 7 controls the cover 6 to move downwards to cover an opening 18 of a cup 3 placed below the cover 6, thereby a burning candle 4 or a burning aromatherapy product inside the cup 3 is extinguished due to a lack of oxygen. Responsive to the roll-up of the lifting rope 7, the cover 6 moves upwards, and the opening of the cup 3 is uncovered.

A shaft of the motor 9 is connected to the rope winding wheel 8 that is wrapped with the lifting rope 7. One end of the lifting rope 7 is connected to the cover 6. Responsive to the motor 9 controlling the rope winding wheel 8 to rotate to release the lifting rope 7, the cover 6 moves downwards due to gravity to cover the cup 3 placed on an upper end face of the base 1 (in other words, the opening 18 of the cup 3 below the cover 6).

Responsive to the motor 9 controlling the rope winding wheel 8 to rotate to roll up the lifting rope 7, the cover 6 is pulled upwards by the lifting rope 7, and the opening 18 of the cup 3 is uncovered. When the cover 6 moves upwards, it can be hidden in the main body 5. During next use, a user can directly ignite the candle 4 or the aromatherapy product inside the cup 3, or take out the cup 3, ignite the candle 4 or the aromatherapy product inside the cup 3, and then put the cup 3 back to the upper end face of the base 1.

The motor 9 and the rope winding wheel 8 are disposed inside the base 1, and one end of the lifting rope 7 in the rope winding wheel 8 passes through the support 2 which is hollow and is connected to the cover 6 inside the main body 5. The motor 9 controls the release or the roll-up of the cover 6 through the lifting rope 7. Alternatively, the motor 9 and the rope winding wheel 8 may 8 may be disposed inside the main body 5, and the lifting rope 7 in the rope winding wheel 8 is directly connected to the cover 6.

The base 1 is provided with a circuit 11, and the circuit 11 is connected to the motor 9 through a wire to control the motor 9 to perform forward or reverse rotation, thereby controlling the release or the roll-up of the lifting rope 7 to uncover or cover the opening 18 of the cup 3. When the forward rotation is clockwise, the reverse rotation is counterclockwise. When the forward rotation is counterclockwise, the reverse rotation is clockwise.

During use, when a higher cup 3 needs to be used, there is no need to adjust a release length of the lifting rope 7. Responsive to the motor 9 controlling the rope winding wheel 8 to rotate to release the lifting rope 7, after the cover 6 moves downwards to cover the cup 3 placed below the cover 6, the cover 6 stops moving. When the motor 9 can continue to release the lifting rope 7, due to flexibility of the lifting rope 7, the release length of the lifting rope 7 does not need to be adjusted, and the cover 6 remains stationary and covers the opening 18 of the cup 3, which is suitable for cups 3 of different heights. Alternatively, a gravity ball 14 may also be installed in the lifting rope 7 at an upper end of the cover 6. After the cover 6 moves downwards to cover the cup 3 placed below the cover 6, the cover 6 stops moving. When the motor 9 continues to release the lifting rope 7, the gravity ball 14 continues to pull the lifting rope 7 downwards. When the higher cup 3 needs to be used, there is no need to adjust the release length of the lifting rope 7, which is suitable for the cups 3 of different heights.

The circuit 11 can set a set time point of the motor, and can control the motor 9 to start to rotate at the set time point. Through the circuit 11, the motor 9 can be set to start to rotate at the set time point to control the cover 6 to start to cover the opening 18 of the cup 3 at the set time point.

The circuit 11 can be communicatively connected to a timing remote control, and the set time point of the motor 9 can be set through the timing remote control. Responsive to reaching the set time point, the circuit 11 controls the cover 6 to cover the cup 3, thereby the candle or the aromatherapy product inside the cup 3 is extinguished.

The base 1 includes a battery 10. The battery 10 can provide power to the circuit 11. Alternatively, a wire of a power interface 12 can be directly used to provide power to the circuit 11 or charge the battery 10.

The upper end face of the base 1 is provided with a positioning ring 13 that matches a bottom of the cup 3. The bottom of the cup 3 can be placed in the positioning ring 13. This makes it convenient to place the cup 3 in a centered manner, and also makes it convenient to more accurately cover the opening of the cup 3 when the cover 6 moves downwards, preventing the cup 3 from being inaccurately covered due to displacement of the cup 3 during use.

In the embodiment shown in FIG. 3, for example, after the candle 4 is ignited, the candle 4 only needs to burn for 30 minutes. Through the circuit 11, the user can set to automatically extinguish the candle 4 after 30 minutes. After 30 minutes after igniting the candle 4, the circuit 11 controls the motor 9 to rotate to release the cover 6. The cover 6 moves downwards and covers the opening 18 of the cup 3, thereby the cover 3 is covered. As a result, the burning candle 4 inside the cup 3 is extinguished due to the lack of oxygen. After the candle 4 is extinguished, the circuit 11 controls the motor 9 to rotate to roll up the lifting rope 7. The cover 6 moves upwards and is hidden inside the main body 5, and the opening 18 of the cup 3 is uncovered. During next use, the user may directly ignite the candle 4 or the aromatherapy product inside the cup 3, or take out the cup 3, ignite the candle 4 or the aromatherapy product inside the cup 3, and then place the cup 3 in the positioning ring 13. The motor 9 and the lifting rope 7 are combined to control the release or the roll-up of the cover 6. The extinguishing time of the candle and the aromatherapy product in a burning process is automatically controlled, and there is no need to manually extinguish the candle and the aromatherapy product. The combination of the motor 9 and the lifting rope 7 make it easy to control the cover 6 to move upwards or downwards, which is suitable for the cups 3 of different heights. This achieves more convenient and reasonable use.

In a second embodiment shown in FIG. 4 to FIG. 7, an automatic extinguisher includes a base 1, a main body 5, a cover 6, a motor 9, and a circuit 11. The base 1 is provided with a plurality of supports 2 connected to the main body 5. The main body 5 is provided with the cover 6 that can be extended and retracted. The motor 9 controls extension and retraction of the cover 6. The motor 9 is connected to the circuit 11. The circuit 11 can control the motor 9 to start to rotate at a set time point, and the motor 9 rotates to control the cover 6 to extend downwards and cover an opening 18 of a cup 3 placed on an upper end face of the base 1, thereby a burning candle 4 or a burning aromatherapy product inside the cup 3 is extinguished due to a lack of oxygen. Responsive to the motor 9 controlling the cover 6 to retract upwards, the opening 18 of the cup 3 is uncovered. During next use, a user can take out the cup and ignite the candle 4 or the aromatherapy product inside the cup.

The cover 6 is slidably matched with a guide post 17. Responsive to the screw 15 rotating to control the nut 16 and the cover 6 to move, the guide post 17 performs guiding and positioning on the cover 6 to prevent the nut 16 from rotating with the screw 15. A screw thread of the screw 15 pushes the nut 16 to make a linear motion, thereby transforming a rotational motion of the screw 15 into the linear motion of the nut 16. The cover 6 slides in a straight line in contact with the guide post 17.

The base 1 is provided with the circuit 11 therein. The circuit 11 is connected to the motor 9 through a wire to control the motor 9 to perform forward or reverse rotation, thereby controlling the cover 6 to move upwards or downwards to uncover or cover the opening 18 of the cup 3.

The circuit 11 can set the set time point of the motor 9, and can control the motor 9 to start to rotate at the set time point. Through the circuit 11, the motor 9 is set to control, after 30 minutes, the cover 6 to extend downwards to cover the opening 18 of the cup 3 placed on the upper end face of the base 1.

A distance of the downward extension or the upward retraction of the cover 6 can be controlled by a quantity of rotation turns of the motor 9 controlled by the circuit 11. For example, responsive to the cover 6 extending downwards to the opening 18 of the cup 3, the circuit 11 controls the motor 9 to rotate reversely for 200 revolutions to retract the cover 6 upwards. When it is necessary to cover the opening 18 of the cup 3, the circuit 11 controls the motor 9 to rotate forward by 200 revolutions, and the cover 6 extends downwards to the opening 18 of the cup 3, thereby the opening 18 of the cup 3 is covered.

For example, after the candle 4 is ignited, the candle 4 only needs to burn for 30 minutes. Through the circuit 11, the user can set to automatically extinguish the candle 4 after 30 minutes. After 30 minutes after igniting the candle 4, the circuit 11 controls the motor 9 to rotate forward by 200 revolutions, and then the motor 9 stops rotating. In this case, the cover 6 extends downwards to the opening 18 of the cup 3, thereby the cover 3 is covered. As a result, the burning candle 4 inside the cup 3 is extinguished due to the lack of oxygen. Alternatively, after the candle 4 is extinguished, the circuit 11 controls the motor 9 to rotate reversely for 200 revolutions to retract the cover 6 upwards, thereby the opening 18 of the cup 3 is uncovered.

The circuit 11 can be communicatively connected to a timing remote control, and the set time point of the motor 9 can be set through the timing remote control. Responsive to reaching the set time point, the circuit 11 controls the cover 6 to cover the cup 3, thereby the candle or the aromatherapy product inside the cup 3 is extinguished.

The base 1 includes a battery 10. The battery 10 can provide power to the circuit 11. Alternatively, a wire of a power interface 12 can be directly used to supply power to the circuit 11. Responsive to the power interface 12 of the circuit 11 being connected, the battery 10 can be charged.

The upper end face of the base 1 is provided with a positioning ring 13 that matches a bottom of the cup 3. The bottom of the cup 3 can be placed in the positioning ring 13. This makes it convenient to place the cup 3 in a centered manner, and also makes it convenient to more accurately cover the opening 18 of the cup 3 when the cover 6 moves downwards, preventing the cup 3 from being inaccurately covered due to displacement of the cup 3 during use.

In a third embodiment shown in FIG. 8 to FIG. 10, an automatic extinguisher includes a base 1, a main body 5, a cover 6, a motor 9, and a circuit 11. An upper end of the base 1 is provided with the main body 5, and the main body 5 is provided with a plurality of first openings 19 and the cover 6 that is rotatable and adjustable. The motor 9 can control the cover 6 to rotate inside the main body 5 to uncover or cover the first openings 19 of the main body 5.

Responsive to a side face of the cover 6 rotating to block the first openings 19 of the main body 5, the first openings 19 of the main body 5 are covered.

The base 1 is provided with the circuit 11 therein. The circuit 11 is connected to the motor 9 through a wire to control the motor 9 to rotate, thereby controlling the cover 6 to rotate inside the main body 5 to automatically uncover or cover the first openings 19 of the main body 5 at set time. Alternatively, the circuit 11 and the battery 10 may be disposed inside or at the upper end of the main body 5.

The circuit 11 can set the set time point of the motor 9, and can control the motor 9 to start to rotate at the set time point. For example, responsive to the second openings 20 of the cover 6 being aligned with the first openings 19 of the main body 5 (in other words, the first openings 19 of the main body 5 are fully uncovered), through the circuit 11, the motor 9 can be set to control the cover 6 to rotate by 90 degrees after 30 minutes. After 30 minutes after the second openings 20 of the cover 6 are aligned with the first openings 19 of the main body 5, the circuit 11 controls the motor 9 to rotate forward by 90 degrees and then stop. At this moment, the cover 6 rotates by 90 degrees, the side face of the cover 6 rotates to block the first openings 19 of the main body 5, and the second openings 20 of the cover 6 are located inside the side face of the main body 5. The first openings 19 of the main body 5 are blocked and covered, and the burning candle 4 inside the cup 3 is extinguished due to the lack of oxygen. After the candle 4 is extinguished, the circuit 11 controls the motor 9 to rotate reversely by 90 degrees or continue to rotate forward by 90 degrees to uncover the first openings 19 of the main body 5.
