An aromatherapy tablet is embedded in the mounting groove. A silicone aromatherapy cover that seals the mounting groove is detachably connected to the connecting tube. A plurality of through holes are opened on the silicone aromatherapy cover. An air source is connected to the air passage.

[0008] Preferably, the connecting cylinder has a connecting groove extending into it, and the silicone aromatherapy cover is fixedly connected to a flexible connecting strip that can extend into the connecting groove. A flexible limiting block with a cross-sectional area larger than that of the connecting groove is fixedly connected to the flexible connecting strip.

[0009] Preferably, a protrusion is fixedly connected to the end of the silicone aromatherapy cap away from the flexible connecting strip, and an annular insert is fixedly connected to the connecting cylinder on one side of the mounting groove, and the protrusion can be embedded in the insert.

[0010] Preferably, the outer peripheral wall of the connecting cylinder is provided with a side-sloping air hole communicating with the air passage. The air outlet direction of the side-sloping air hole is set towards the air outlet direction of the through hole. The air passage located between the side-sloping air hole and the mounting groove is configured to be open and closed. When the air passage is open, the air volume of the air source is increased. When the air passage is blocked, the air volume of the air passage is reduced.

[0011] Preferably, the air duct is connected to a solenoid valve, the air source includes a fan, a battery, and a circulation control circuit, and the battery is coupled to the electromagnet and the fan through the circulation control circuit.

[0012] Preferably, the cycle control circuit includes a large resistor, a small resistor, a first normally closed switch, a second normally closed switch, a normally open switch, and a relay. The normally open switch and the small resistor are connected in series and coupled to the fan. The first normally closed switch and the large resistor are connected in series and coupled to the fan. The second normally closed switch is connected in series with the solenoid valve. The relay controls the first normally closed switch, the second normally closed switch, and the normally open switch.

[0013] Preferably, the loop control circuit includes

[0014] The first trigger circuit is coupled to the battery via the main control button. The first trigger circuit is triggered by a high level and outputs a low-level first trigger signal.

[0015] A first timing circuit, wherein the input terminal of the first timing circuit is coupled to the output terminal of the first trigger circuit, and the first timing circuit starts timing in response to the first trigger signal and outputs the first timing signal within the timing period;

[0016] The first switching circuit has its controlled terminal coupled to the output terminal of the first timing circuit, its power-on terminal coupled to the battery, and its discharge terminal coupled to the relay.

[0021] This utility model has the following beneficial effects:

[0022] This invention allows the user to hold the vacuum cleaner by hand. After pressing the main control button, the battery discharges, causing the first trigger circuit to output a signal. This triggers the first timing circuit and energizes the first switching circuit to control the relay, opening the first and second normally closed switches. This energizes the small resistor and the fan, causing the fan to output a strong airflow. When the timing ends, the second trigger circuit is activated, and the second timing circuit starts again. This de-energizes the relay, closing the first and second normally closed switches and opening the normally open switch. The fan's airflow decreases, and the solenoid valve blocks the air passage. The timing ends again, energizing the relay, and the cycle repeats until the user disconnects the power. The mounting slot continuously blows air, and the changing airflow releases and diffuses the fragrance from the aromatherapy tablets. Attached Figure Description

[0035] A handheld vacuum cleaner with a silicone aromatherapy cap, such as Figures 1 to 3 As shown, it includes a connecting cylinder 1, an air passage is fixedly connected to the inner wall of the connecting cylinder 1, the outer peripheral wall of the connecting cylinder 1 is recessed inward to form an installation groove 3, the inner wall of the installation groove 3 is provided with a vent hole 6 communicating with the air passage, an aromatherapy tablet 5 is embedded in the installation groove 3, and a silicone aromatherapy cover 8 that seals the installation groove 3 is detachably connected to the connecting cylinder 1, the silicone aromatherapy cover 8 is provided with several through holes 9, and an air source is connected to the air passage.

[0036] The connecting cylinder 1 has a connecting groove 4 extending through its interior. A flexible connecting strip 10 that can extend into the connecting groove 4 is fixedly connected to the silicone aromatherapy cover 8. A flexible limiting block 11 with a cross-sectional area larger than that of the connecting groove 4 is fixedly connected to the flexible connecting strip 10. A protrusion is fixedly connected to the end of the silicone aromatherapy cover 8 away from the flexible connecting strip 10. An annular insert 7 located on one side of the mounting groove 3 is fixedly connected to the connecting cylinder 1. The protrusion can be embedded in the insert 7. A side-sloping air hole 2 communicating with the air passage is opened on the outer peripheral wall of the connecting cylinder 1. The air outlet direction of the side-sloping air hole 2 is set towards the air outlet direction of the through hole 9. The air passage between the side-sloping air hole 2 and the mounting groove 3 can be opened and closed. When the air passage is open, the air volume of the air source is increased. When the air passage is blocked, the air volume of the air passage is reduced.

[0037] The air passage is connected to a solenoid valve 27. The air source includes a fan 23, a battery 12, and a circulation control circuit. The battery 12 is coupled to the electromagnet and the fan 23 through the circulation control circuit.

[0038] like Figure 4 As shown, the cycle control circuit includes a large resistor 25, a small resistor 22, a first normally closed switch 24, a second normally closed switch 26, a normally open switch 21, and a relay 20. The normally open switch 21 and the small resistor 22 are connected in series and coupled to the fan 23. The first normally closed switch 24 and the large resistor 25 are connected in series and coupled to the fan 23. The second normally closed switch 26 is connected in series with the solenoid valve 27. The relay 20 controls the first normally closed switch 24, the second normally closed switch 26, and the normally open switch 21.

[0039] Preferably, the loop control circuit includes a first trigger circuit 14, a first timing circuit 15, a first switching circuit 16, a second trigger circuit 17, a second timing circuit 18, and a second switching circuit 19. The first trigger circuit 14 and the second trigger circuit 17 respectively include an RS flip-flop and a D flip-flop. The first timing circuit 15 includes a minimum system based on a 555 timer chip. The second timing circuit 18 includes an RC delay circuit. The first switching circuit 16 and the second switching circuit 19 both include transistor switches.

[0040] The first trigger circuit 14 is coupled to the battery 12 via the main control button 13. The first trigger circuit 14 is triggered by a high-level signal and outputs a low-level first trigger signal. The input terminal of the first timing circuit 15 is coupled to the output terminal of the first trigger circuit 14. Upon responding to the first trigger signal, the first timing circuit 15 starts timing and outputs a first timing signal within the timing period. The controlled terminal of the first switching circuit 16 is coupled to the output terminal of the first timing circuit 15. The energized terminal of the first switching circuit 16 is coupled to the battery 12. The discharging terminal of the first switching circuit 16 is coupled to the relay 20. The input terminal of the second trigger circuit 17 is coupled to the first switching circuit 14. The output terminal of the first switch circuit 16 is coupled to the second trigger circuit 17, which outputs a low-level second trigger signal when the level of the output terminal of the first switch circuit 16 changes from high to low. The input terminal of the second timing circuit 18 is coupled to the output terminal of the second trigger circuit 17. The second timing circuit 18 starts timing in response to the second trigger signal and outputs a second timing signal after the timing time. The power terminal of the second switch circuit 19 is coupled to the battery 12. The discharge terminal of the switch circuit is coupled to the input terminal of the first trigger circuit 14. The controlled terminal of the second switch circuit 19 is coupled to the output terminal of the second timing circuit 18. The second switch circuit 19 starts conducting in response to the second timing signal.

[0041] In actual operation, the user can hold the handle to operate the vacuum cleaner. During operation, the user can manually press the main control button 13, causing the battery 12 to discharge the first trigger circuit 14. The first trigger circuit 14 then outputs a first trigger signal in response to a high-level signal. A low-level first trigger signal is sent to the first timing circuit 15, which begins timing. During the timing period, the first switching circuit 16 is energized by the first timing circuit 15. This energizes the relay 20, opening the first normally closed switch 24 and the second normally closed switch 26, thereby energizing the small resistor 22 and the fan 23. The fan 23 can then output a relatively high voltage. With strong winds, after the timing period ends, the level at the discharge terminal of the first switch circuit 16 changes from high to low, triggering the second trigger circuit 17 and outputting the second trigger circuit 17 to the second timing circuit 18. The second timing circuit 18 then starts timing, and after the timing ends, it outputs a second timing signal to the first trigger circuit 14. During this process, the relay 20 is de-energized, the first normally closed switch 24 and the second normally closed switch 26 are closed, and the normally open switch 21 is opened. At this time, the fan 23 has a lower airflow due to the large resistance 25, and the solenoid valve 27 blocks the air passage. After the timing ends, the relay 20 is energized again and then repeats the operation until the user presses the main control button 13 to cut off the power.

[0042] During this process, the mounting slot 3 continuously blows air, allowing the fragrance on the aromatherapy tablet 5 to be released. The airflow in the mounting slot 3 increases and decreases during this process. When the airflow increases, the air passage and solenoid valve 27 are unobstructed, and the two side air holes 2 can blow air simultaneously, allowing the fragrance leaving the mounting slot 3 to diffuse to both sides. When the airflow decreases, the air passage is blocked, and only the mounting slot 3 blows air. In this way, the handheld vacuum cleaner can diffuse the fragrance of the aromatherapy over a relatively wide range.

[0043] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
