Description

Technical Field

[0001] This utility model belongs to the field of aromatherapy equipment technology, specifically relating to a portable aromatherapy sprayer. Background Technology

[0002] Aromatherapy devices are widely used in enclosed spaces such as homes, offices, and vehicles, purifying the air, regulating mood, and improving the environment by diffusing fragrances. Traditional aromatherapy devices mainly include heated, volatile, and ultrasonic atomizing types. However, existing aromatherapy devices have many shortcomings in terms of portability and user experience.

[0003] Chinese patent publication number CN104721871A discloses a handheld aromatherapy device that uses an air pump to atomize essential oils and incorporates a one-way valve on the essential oil bottle to prevent leakage. While this device solves the problem of liquid leakage during handheld use, its air pump structure is quite noisy. Another example is patent CN215274764U, which discloses a portable, controllable electronic aromatherapy diffuser. Although it is smaller in size, its functionality is relatively limited.

[0004] The existing technology has the following main problems: insufficient portability: most aromatherapy products are not convenient to carry and are prone to liquid leakage during use; poor user experience: traditional ultrasonic atomizers consume a lot of energy and may pose potential harm to the human body. Utility Model Content

[0005] The purpose of this invention is to provide a portable aromatherapy sprayer that is easy to carry and has a leak-proof function.

[0006] The specific technical solution adopted in this utility model is as follows: A portable aromatherapy sprayer includes a housing containing a liquid storage mechanism, a pumping mechanism, and a battery assembly. A top cover is mounted on the upper end of the housing, and multiple atomizing nozzles are evenly arranged on the four sides of the top cover. A leak-proof mechanism is installed inside the top cover, and a switch is mounted on the top of the top cover. The liquid storage mechanism includes a liquid reservoir that is locked and fixed within the housing. A sealing plug is installed at the mouth of the reservoir, and a vent pipe and a drain pipe inserted into the bottom of the reservoir are mounted on the sealing plug. The pumping mechanism includes an air cylinder. A piston is slidably mounted inside the cylinder, and a telescopic rod is connected to the piston. An air inlet and an exhaust outlet are located at the end of the cylinder furthest from the telescopic rod. The leak-proof mechanism includes a liquid-distributing cylinder with an internal cavity. A sealing plug is installed inside the liquid-distributing cylinder, and a guide rod is connected to the upper end of the sealing plug. A spring is sleeved on the guide rod. The pumping mechanism is connected to the liquid storage mechanism via a second connecting pipe. The liquid storage mechanism is connected to the leak-proof mechanism via a first connecting pipe, and the leak-proof mechanism is connected to the atomizing nozzle via a third connecting pipe.

[0007] In a preferred embodiment, the side wall of the outer casing is provided with a vent hole for air intake.

[0008] In a preferred embodiment, the liquid storage mechanism further includes a pressure cap for pressing the sealing plug, the pressure cap being threadedly connected to the outer wall of the reservoir opening, and the vent pipe being connected to the exhaust port via a connecting pipe two.

[0009] In a preferred embodiment, the pumping mechanism further includes a one-way valve one installed at the air inlet and a one-way valve two installed at the air outlet, and the outer end of the telescopic rod is fixedly connected to the outer wall of the air cylinder.

[0010] In a preferred embodiment, the leak-proof mechanism is used to seal the connection between the first connecting pipe and the third connecting pipe. The upper end of the spring rests against the inner wall of the upper end of the dispensing cylinder, and the lower end of the spring rests against the sealing plug. The first connecting pipe is connected to the lower end of the dispensing cylinder, and the third connecting pipe is connected to the side wall of the dispensing cylinder.

[0011] In a preferred embodiment, the battery assembly integrates a control module, which is electrically connected to the switch and the telescopic rod. The control module also includes a wireless communication unit that supports Bluetooth or Wi-Fi connectivity for communication with mobile devices.

[0012] The technical effects achieved by this utility model are as follows: This practical device has a compact structure, small size, and is easy to carry. In addition, the extension and retraction of the telescopic rod drives the piston to move in the air cylinder, thereby pumping air into the liquid storage mechanism. The gas squeezes out the aromatherapy solution in the liquid storage mechanism and sprays it out from the atomizing nozzle. By using the telescopic rod instead of an air pump or ultrasonic atomizer as the power source, not only is the noise reduced and the operation more stable, but it also avoids harm to the human body. This invention incorporates a leak-proof mechanism between the liquid storage mechanism and the atomizing nozzle. When the equipment is not in use, the leak-proof mechanism seals the channel between the liquid storage mechanism and the atomizing nozzle, preventing the solution from leaking out of the atomizing nozzle and improving leak-proof performance.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein.

[0019] Please see the appendix Figures 1 to 5As shown, this utility model provides a portable aromatherapy sprayer, including a housing 1. The housing 1 contains a liquid storage mechanism 2, a pumping mechanism 3, and a battery assembly 8. A top cover 4 is installed at the upper end of the housing 1. Multiple atomizing nozzles 5 are evenly arranged on the four sides of the top cover 4. A leak-proof mechanism 6 is installed inside the top cover 4, and a switch 7 is installed at the top of the top cover 4. The liquid storage mechanism 2 includes a liquid reservoir 21 that is locked and fixed inside the housing 1. A sealing plug 22 is installed at the mouth of the reservoir 21, and a vent pipe 23 and a drain pipe 24 inserted into the bottom of the reservoir are installed on the sealing plug 22. The pumping mechanism 3 includes an air cylinder 31. A piston 32 is slidably installed inside the cylinder 31, and a telescopic rod 33 is connected to the piston 32. An air inlet 34 and an exhaust outlet 35 are provided at the end of the cylinder 31 away from the telescopic rod 33. The anti-leakage mechanism 6 includes a liquid distribution cylinder 61 with an internal cavity. A sealing plug 62 is provided inside the liquid distribution cylinder 61. A guide rod 63 is connected to the upper end of the sealing plug 62, and a spring 64 is sleeved on the guide rod 63. The pumping mechanism 3 is connected to the liquid storage mechanism 2 through a second connecting pipe 38. The liquid storage mechanism 2 is connected to the anti-leakage mechanism 6 through a first connecting pipe 26. The anti-leakage mechanism 6 is connected to the atomizing nozzle 5 through a third connecting pipe 51. When the device is in use, the extension and retraction of the telescopic rod 33 in the air pumping mechanism 3 drives the piston 32 to move inside the air cylinder 31, drawing air into the air cylinder 31. Then, through the connection of the second connecting pipe 38, the air is pumped into the liquid storage tank 21 of the liquid storage mechanism 2. The gas squeezes the solution out of the liquid storage tank 21. Through the connection of the first connecting pipe 26, the solution is pumped into the cavity of the liquid distribution cylinder 61 of the leak-proof mechanism 6. The pressure of the solution pushes the sealing plug 62 upward, so that the first connecting pipe 26 and the third connecting pipe 51 are connected through the cavity of the liquid distribution cylinder 61. Then, the solution is squeezed into the third connecting pipe 51 and finally sprayed out from the atomizing nozzle 5, completing the release of the solution.

[0020] Please see Figure 1 As shown, the side wall of the outer casing 1 is provided with a vent hole 11 for the air inlet 34 to draw in air; A vent hole 11 is provided on the side wall of the outer shell 1 to facilitate communication between the inside and outside of the outer shell 1, so that air can enter the inside of the outer shell 1 for intake by the air inlet 34.

[0021] Please see Figure 4 As shown, the liquid storage mechanism 2 also includes a cap 25 for pressing the sealing plug 22. The cap 25 is threadedly connected to the outer wall of the mouth of the liquid storage vessel 21. The vent pipe 23 is connected to the exhaust port 35 through the connecting pipe 38. The function of the sealing plug 22 is to seal the opening of the reservoir 21, allowing gas and liquid to enter and exit only through the vent pipe 23 and the exhaust port 35, preventing air leakage. It allows gas to enter and squeeze out the liquid. The function of the pressure cap 25 is to tighten it at the opening of the reservoir 21 through a threaded connection, compressing the sealing plug 22 and preventing excessive internal pressure in the reservoir 21 from pushing the sealing plug 22 out. The threaded connection of the pressure cap 25 makes it easy to unscrew and remove the sealing plug 22, facilitating the replenishment of aromatherapy solution into the reservoir 21, thereby improving the service life of the device.

[0022] Please see Figure 2 and Figure 3 As shown, the air pumping mechanism 3 also includes a one-way valve 36 installed at the air inlet 34 and a one-way valve 37 installed at the air outlet 35, and the outer end of the telescopic rod 33 is fixedly connected to the outer wall of the air cylinder 31. When the atomizing nozzle 5 sprays the solution outward, the pumping mechanism 3 needs to provide power for the solution to flow from the reservoir 21 to the atomizing nozzle 5. By retracting the telescopic rod 33, the piston 32 is driven to move away from the air inlet 34, which can draw outside air into the air cylinder 31 through the air inlet 34. Then, by extending the telescopic rod 33, the piston 32 is driven to move closer to the exhaust port 35, which discharges the drawn-in air through the exhaust port 35 to the connecting pipe 38, and through the connecting pipe 38 to the vent pipe 23, and finally into the reservoir 21. By pumping air into the reservoir 21, the solution is squeezed out. The purpose of setting one-way valves at the air inlet 34 and the air outlet 35 is to control the direction of gas flow. One-way valve 36 is set on the air inlet 34 so that outside air can flow through the air inlet 34 into the air cylinder 31, while the air in the air cylinder 31 cannot flow back into the air. One-way valve 37 is set on the air outlet 35 so that the gas in the air cylinder 31 can be discharged from the air outlet 35 into the connecting pipe 38, while the gas in the connecting pipe 38 cannot flow back into the air cylinder 31. It should be noted that the pumping mechanism 3 pumps air into the reservoir 21 at a slow rate, meaning that the volume of gas pumped into the reservoir 21 is approximately equal to the volume of solution flowing out of the reservoir 21. This allows the atomizing nozzle 5 to immediately or slowly stop spraying solution when the pumping mechanism 3 stops pumping air into the reservoir 21, thus achieving start-stop control of the aromatherapy spray. Conversely, the pumping mechanism 3 draws in air from the outside at a relatively fast rate to avoid intermittent spraying from the atomizing nozzle 5.

[0023] The leak-proof mechanism 6 is used to block the connection between the first connecting pipe 26 and the third connecting pipe 51. The upper end of the spring 64 is pressed against the inner wall of the upper end of the liquid separator 61, and the lower end of the spring 64 is pressed against the sealing plug 62. The first connecting pipe 26 is connected to the lower end of the liquid separator 61, and the third connecting pipe 51 is connected to the side wall of the liquid separator 61. When the device is working, the pressure of the solution flowing out of the reservoir 21 will push the sealing plug 62 upward, thus connecting the first connecting pipe 26 and the third connecting pipe 51 through the inner cavity of the dispensing cylinder 61. The solution flows from the first connecting pipe 26 to the third connecting pipe 51 and is then sprayed out through the atomizing nozzle 5. When the device stops working, the pumping mechanism 3 stops pumping air into the reservoir 21. The pressure in the reservoir 21 gradually decreases with the flow of the solution, approaching atmospheric pressure. Then, the elastic force of the spring 64 pushes the sealing plug 62 downward, isolating the connection between the first connecting pipe 26 and the third connecting pipe 51, thereby preventing leakage during transport. The guide rod 63 guides the up and down movement of the sealing plug 62.

[0024] The battery assembly 8 integrates a control module, which is electrically connected to the switch 7 and the telescopic rod 33. The control module also includes a wireless communication unit that supports Bluetooth or Wi-Fi connectivity for communication with mobile devices. During the start-up and shutdown of the device, pressing switch 7 sends a signal to the control module integrated in the battery pack 8. The control module controls the extension and retraction of the telescopic rod 33 to start spraying. When switch 7 is pressed again, the control module controls the telescopic rod 33 to stop working, thus controlling the device. The side wall of the outer casing 1 is also equipped with a charging interface (not shown in the figure) to facilitate charging of the battery pack 8. (The control operation of the telescopic rod 33 by the control module and the charging method of the battery pack 8 are existing technologies and will not be described in detail here.) In addition, the wireless communication unit included in the control module allows for easy operation of the device's start and stop via a mobile APP, enabling diversified device control (again, the communication connection between the device and the mobile APP is existing technology and will not be elaborated further here).

[0025] Please see Figure 1 and Figure 2 As shown, the outer shell 1 and the upper cover 4 are connected by bolts, which facilitates disassembly and subsequent maintenance.

[0026] The working principle of this utility model is as follows: When the device is in use, the extension and retraction of the telescopic rod 33 in the air pumping mechanism 3 drives the piston 32 to move inside the air cylinder 31, drawing air into the air cylinder 31. Then, through the connection of the second connecting pipe 38, the air is pumped into the liquid storage tank 21 of the liquid storage mechanism 2. The gas squeezes the solution in the liquid storage tank 21 out. Through the connection of the first connecting pipe 26, the solution is pumped into the cavity of the liquid distribution cylinder 61 of the leak-proof mechanism 6. The pressure of the solution pushes the sealing plug 62 upward, so that the first connecting pipe 26 and the third connecting pipe 51 are connected through the cavity of the liquid distribution cylinder 61. Then, the solution is squeezed into the third connecting pipe 51 and finally sprayed out from the atomizing nozzle 5, completing the release of the solution.

[0027] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
