Description

Technical Field

[0001] This utility model relates to the field of essential oil atomizer technology, specifically to an essential oil leak-proof device. Background Technology

[0002] An essential oil atomizer is a device that transforms essential oils into tiny particles and diffuses them into the air. The aromatic molecules and negative ions released after atomization can adsorb and degrade harmful pollutants in the air, such as benzene and formaldehyde, and can also eliminate harmful microorganisms in the air, thus purifying the air. Different essential oils have different effects; for example, lavender essential oil can help with sleep and relaxation, peppermint essential oil can refresh the mind, and tea tree essential oil has antibacterial and anti-inflammatory effects. Through atomization and inhalation, the effective components of essential oils can be absorbed by the body more quickly, thereby exerting their health benefits.

[0003] Existing atomizers typically utilize the high-speed airflow of compressed air when it is sprayed through a small hole. According to the Venturi principle, when the high-pressure gas is accelerated and ejected, a negative pressure is generated near the nozzle. Through the siphon effect, the liquid medicine in the medicine storage tank is guided to the nozzle through the water suction pipe and mixed with the high-speed airflow. Together, they collide with the baffle to generate aerosol particles.

[0004] While existing essential oil atomizing devices offer numerous benefits during use, they still suffer from the following problems: their leak prevention for atomized essential oils is not perfect, leading to leakage due to internal and external pressure differences after atomization. This results in poor sealing of the atomizer, and when the atomizer is tilted, essential oil inside the reservoir may leak out, causing waste of essential oil inside the atomizer. Utility Model Content

[0005] In view of the problems in the prior art, this utility model provides an essential oil leak prevention device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an essential oil leak-proof device, including a shell, an atomizing head, a main frame, a pressure cap, an atomizing bracket, a leak-proof mechanism, an atomizing core, and an air inlet. The atomizing head is threadedly connected to the upper outer wall of the shell. A top cover is snapped into the upper part of the atomizing head. The main frame is screwed into the shell. A pressure cap is set inside the main frame. Atomizing caps are placed on both sides of the upper part of the pressure cap. A first atomizing chamber for primary screening of atomized particles is reserved between the atomizing cap and the pressure cap. A second atomizing chamber for secondary screening of atomized particles is reserved between the atomizing cap and the top cover. An air inlet is integrally formed on the inner wall of the first atomizing chamber. An atomizing bracket is interference-fitted into the lower part of the pressure cap. An oil return hole is opened inside the atomizing bracket. A leak-proof mechanism is set inside the oil return hole. The leak-proof mechanism consists of a hole cover, a leak-proof component, and a support spring.

[0007] By adopting the above technical solution, the atomized particles can be screened twice by setting up a first atomization chamber and a second atomization chamber, making the final output atomized particles more delicate and uniform, improving the atomization effect of essential oils and the user experience. In addition, the leak-proof mechanism can effectively prevent essential oil leakage, improve the safety and reliability of the device, and reduce waste and environmental pollution caused by essential oil leakage.

[0008] Specifically, a base is screwed to the lower outer wall of the outer casing, and a control button is snapped onto one side of the lower outer wall of the main frame. The end of the control button away from the main frame protrudes from the outer side of the outer casing.

[0009] By adopting the above technical solution, the base facilitates the installation and fixation of the outer shell, ensuring the stability of the device during use. The control button protrudes from the outside of the outer shell, making it easy for users to operate and conveniently control the opening and closing of the device and adjust relevant parameters, thereby realizing the control of the device. Furthermore, an ambient light is connected to the screw at the lower end of the outer shell. The light generated by the ambient light when it is working can illuminate the base to improve the overall aesthetics of the device.

[0010] Specifically, both sides of the upper outer wall of the cover are provided with mist outlets, and the mist outlets are connected to the interior of the second atomizing chamber. A decorative piece is provided at the upper end of the mist outlet, and the mist outlet protrudes from the upper end of the decorative piece.

[0011] By adopting the above technical solution, the atomized essential oil is screened through the first atomization chamber and the second atomization chamber, and then discharged into the environment through the mist outlet. This controls the flow trajectory of the atomized essential oil, and the decorative piece can cover the top cover, which can play a certain role in beautification and improve the overall aesthetics of the device.

[0012] Specifically, an oil suction tube is inserted into the lower outer wall of the atomizing core, and liquid storage bottles for storing essential oils are placed on both sides of the inner wall of the main frame. The liquid storage bottles are threadedly connected to the caps, and the lower end of the oil suction tube extends into the liquid storage bottles.

[0013] By adopting the above technical solution, the essential oil in the storage bottle can be delivered to the atomizing core for atomization through the oil suction tube, ensuring the stability and accuracy of the essential oil supply, and the threaded connection ensures that the storage bottle is easy to replace.

[0014] Specifically, the atomizing bracket has an airflow channel inside, the end of the air inlet head extends into the airflow channel, and a sealing silicone pad is glued and fixed to the end of the air inlet head, and the sealing silicone pad is in contact with the inner wall of the airflow channel. An atomizing core is provided on one side of the upper outer wall of the atomizing bracket, and air inlets are provided on both sides of the outer wall of the pressure cap. The atomizing core is connected to the inside of the air inlet through the airflow channel and the air inlet head.

[0015] By adopting the above technical solution, the sealing silicone gasket ensures the seal between the air inlet head and the airflow channel, ensuring the airflow of gas into the airflow channel through the air inlet head. The air pump provides air to the airflow channel through the air inlet and the atomizing head, ensuring the atomization process of the essential oil and guaranteeing atomization efficiency. When the gas impacts the atomizing core through the air inlet and the airflow channel, the inside of the liquid storage bottle is under negative pressure, while the inside of the first atomizing chamber is under high pressure. The pressure inside the first atomizing chamber can act on the leak-proof component, thereby forcing the leak-proof component to squeeze the support spring. Since there is a gap between the leak-proof component and the orifice cap in the initial state, the pressure during the atomization process will cause the gap between the leak-proof component and the orifice cap to increase, thus allowing the gas inside the first atomizing chamber to... The essential oil enters the reservoir through the return oil hole and gap. At this time, due to the pressure difference, the atomizing core draws the essential oil from the reservoir through the suction tube and atomizes it. During atomization, the atomized essential oil gathers in the first atomization chamber and is filtered through the atomization cap, causing large particles of atomized essential oil to gather. The conical shape of the upper part of the inner wall of the atomization cap guides the gathered essential oil, causing it to flow towards the return oil hole. The weight of the gathered essential oil compresses the leak-proof component and increases the pressure on the support spring. Under the combined action of air pressure and weight, the gathered essential oil flows back into the reservoir through the gap between the leak-proof component and the cap, realizing the recycling of essential oil and avoiding waste.

[0016] Specifically, the support spring is sleeved on the lower end of the leak-proof component, and the leak-proof component is elastically connected to the lower end of the inner wall of the oil return hole through the support spring. The hole cover is sleeved on the upper end of the leak-proof component. A limiting plate for restricting the use position is fused to one side of the inner wall of the atomizing cover, and the lower end face of the limiting plate is in contact with the upper end face of the hole cover.

[0017] By adopting the above technical solution, the inner wall of the oil return hole is designed in a stepped shape, which can work with the limiting plate to restrict the position of the hole cover and keep the hole cover relatively stable inside the oil return hole. Due to the support spring supporting the leak-proof component, the gap between the leak-proof component and the hole cover is controlled, thereby achieving the sealing of the oil return hole and the storage bottle. When the device is tilted, the leak-proof component and the support spring are tilted simultaneously, thereby decomposing the direction of gravity of the leak-proof component. The original vertical downward gravity of the leak-proof component is decomposed into a component force along the direction of the support spring and a component force perpendicular to the direction of the support spring. As a result, the component force along the direction of the support spring becomes smaller, and the force on the support spring also decreases. Therefore, under the condition that the elastic force of the support spring is constant, the elastic force of the support spring will push the leak-proof component to move towards the inside of the hole cover, making the blockage of the oil return hole more tight, so that the essential oil inside the storage bottle will not leak out, thus achieving the purpose of preventing leakage of essential oil.

[0018] Specifically, air pumps for providing air sources are installed on the lower ends of the outer walls on both sides of the main frame. A gas pipeline is interference-fitted to the exhaust end of the air pump, and the other end of the gas pipeline is interference-fitted to the inside of the air inlet. The air pump is connected to the inside of the air inlet head through the gas pipeline and the air inlet.

[0019] By adopting the above technical solution, the air pump can ensure the supply of gas flow and pressure required during the atomization process, and can provide gas to the inside of the air inlet head through the gas pipeline and the air flow channel of the air inlet, thereby realizing the gas supply for the atomizing core. Furthermore, a solenoid valve is installed on the outside of the gas pipeline. When the user presses the control button protruding from the outside of the outer shell to turn on the device, the air pumps on both sides of the main frame can start working and, in conjunction with the solenoid valve, control the airflow. It can drive a single air pump to work or two air pumps to work simultaneously, so as to realize the discharge of a single atomized essential oil from the two mist outlets or the simultaneous discharge of atomized essential oil from both sides.

[0020] The beneficial effects of this utility model are:

Detailed Implementation

[0039] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0040] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 , Figure 14As shown, the essential oil leak-proof device of this utility model includes a shell 1, an atomizing head 2, a main frame 3, a pressure cap 4, an atomizing bracket 5, a leak-proof mechanism 6, an atomizing core 52, and an air inlet 42. The atomizing head 2 is threadedly connected to the upper outer wall of the shell 1. A top cover 22 is snapped into the upper part of the atomizing head 2. The main frame 3 is screwed into the shell 1. A pressure cap 4 is provided inside the main frame 3. Atomizing covers 41 are placed on both sides of the upper part of the pressure cap 4. The atomizing covers 41 and the pressure cap are connected. A first atomizing chamber 45 is reserved between the atomizing cap 41 and the upper cover 22 for primary screening of atomized particles. A second atomizing chamber 46 is reserved between the atomizing cap 41 and the upper cover 22 for secondary screening of atomized particles. An air inlet head 43 is integrally formed on the inner wall of the first atomizing chamber 45. An atomizing bracket 5 is interference-fitted to the lower end of the inner cover 4. An oil return hole 53 is opened inside the atomizing bracket 5. An anti-leakage mechanism 6 is set inside the oil return hole 53. The anti-leakage mechanism 6 consists of a hole cover 61, an anti-leakage component 62, and a support spring 63.

[0041] In use, by setting the first atomizing chamber 45 and the second atomizing chamber 46, the atomized particles can be screened twice, making the final output atomized particles more delicate and uniform, improving the atomization effect of essential oil and the user experience. In addition, the leak-proof mechanism 6 can effectively prevent essential oil leakage, improve the safety and reliability of the device, and reduce waste and environmental pollution caused by essential oil leakage.

[0042] To control the operation, for example, such as Figure 1 As shown, a base 11 is screwed to the lower outer wall of the outer casing 1, and a control button 33 is snapped onto one side of the lower outer wall of the main frame 3. The end of the control button 33 away from the main frame 3 protrudes from the outer side of the outer casing 1.

[0043] When in use, the base 11 facilitates the installation and fixation of the outer shell 1, ensuring the stability of the device during use. The control button 33 protrudes from the outside of the outer shell 1, making it easy for the user to operate and conveniently control the opening and closing of the device and adjust related parameters, thereby realizing the control of the device. An ambient light is connected to the screw at the lower end of the outer shell 1. The light generated by the ambient light when it is working can illuminate the base 11 to improve the overall aesthetics of the device.

[0044] To control the direction of fog emission, for example, such as Figure 2 As shown, both sides of the upper outer wall of the cover 22 are provided with mist outlets 23, and the mist outlets 23 are connected to the interior of the second atomization chamber 46. A decorative piece 21 is provided on the upper end of the mist outlet 23, and the mist outlet 23 protrudes from the upper end of the decorative piece 21.

[0045] During use, the atomized essential oil is sieved through the first atomization chamber 45 and the second atomization chamber 46, and then discharged into the environment through the mist outlet 23. This controls the flow trajectory of the atomized essential oil, and the decorative piece 21 can cover the top cover 22, which can play a certain role in beautification and improve the overall aesthetics of the device.

[0046] To extract essential oils, for example, such as Figure 3 As shown, an oil suction tube 54 is inserted into the lower outer wall of the atomizing core 52. Both sides of the inner wall of the main frame 3 are equipped with storage bottles 32 for storing essential oils, and the storage bottles 32 are threadedly connected to the cap 4. The lower end of the oil suction tube 54 extends into the storage bottle 32.

[0047] During use, the essential oil in the storage bottle 32 can be delivered to the atomizing core 52 for atomization through the oil suction tube 54, ensuring the stability and accuracy of the essential oil supply, and the threaded connection ensures that the storage bottle 32 is easy to replace.

[0048] For example, to atomize essential oils, such as... Figure 13 As shown, the atomizing bracket 5 has an airflow channel 51 inside, the end of the air inlet head 43 extends into the airflow channel 51, and a sealing silicone pad is glued and fixed to the end of the air inlet head 43. The sealing silicone pad is in contact with the inner wall of the airflow channel 51. An atomizing core 52 is provided on one side of the upper outer wall of the atomizing bracket 5. Air inlets 42 are provided on both sides of the outer wall of the pressure cap 4. The atomizing core 52 is connected to the inside of the air inlet 42 through the airflow channel 51 and the air inlet head 43.

[0049] During use, the sealing silicone gasket ensures the seal between the air inlet head 43 and the airflow channel 51, ensuring the airflow into the airflow channel 51 is sealed. The air pump 31 provides air to the airflow channel 51 through the air inlet 42 and the atomizing head 2, ensuring the atomization process of the essential oil and guaranteeing atomization efficiency. When the gas impacts the atomizing core 52 through the air inlet 42 and the airflow channel 51, the liquid storage bottle 32 is under negative pressure, while the first atomizing chamber 45 is under high pressure. The pressure inside the first atomizing chamber 45 can act on the leak-proof component 62, thereby forcing the leak-proof component 62 to compress the support spring 63. Since there is a gap between the leak-proof component 62 and the orifice cap 61 in the initial state, the pressure during atomization will cause the gap between the leak-proof component 62 and the orifice cap 61 to increase, thus increasing the pressure inside the first atomizing chamber 45. Gas can enter the liquid storage bottle 32 through the oil return hole 53 and the gap. At this time, due to the pressure difference, the atomizing core 52 draws the essential oil inside the liquid storage bottle 32 through the oil suction tube 54 and atomizes the essential oil. During the atomization process, the atomized essential oil will gather in the first atomization chamber 45 and be screened and filtered through the atomization cap 41, so that large particles of atomized essential oil gather. Due to the conical shape of the upper part of the inner wall of the atomization cap 41, the gathered essential oil is guided to flow towards the oil return hole 53. The weight of the gathered essential oil will squeeze the leak-proof component 62 and increase the pressure on the support spring 63. Under the dual action of air pressure and weight, the gathered essential oil will flow back into the liquid storage bottle 32 through the gap between the leak-proof component 62 and the cap 61 along the oil return hole 53, realizing the recycling of essential oil and avoiding waste of essential oil.

[0050] To prevent leakage, for example, such as Figure 7 As shown, the support spring 63 is sleeved on the lower end of the leak-proof component 62, and the leak-proof component 62 is elastically connected to the lower end of the inner wall of the oil return hole 53 through the support spring 63. The hole cover 61 is sleeved on the upper end of the leak-proof component 62. A limiting plate 44 for limiting the use position is fused to one side of the inner wall of the atomizing cover 41. The lower end face of the limiting plate 44 is in contact with the upper end face of the hole cover 61.

[0051] During use, the inner wall of the oil return hole 53 adopts a stepped design, which, together with the limiting plate 44, restricts the position of the hole cover 61, keeping the hole cover 61 relatively stable inside the oil return hole 53. The support spring 63 supports the leak-proof component 62, ensuring that the gap between the leak-proof component 62 and the hole cover 61 is controlled, thus achieving the sealing of the oil return hole 53 and the liquid storage bottle 32. When the device is tilted, the leak-proof component 62 and the support spring 63 are simultaneously tilted, causing the gravity of the leak-proof component 62 to decompose. The originally vertically downward gravity of the leak-proof component 62 is decomposed into a component force along the direction of the support spring 63 and a component force perpendicular to the direction of the support spring 63, thereby causing the gravity along the direction of the support spring 63 to decompose. As the force in the direction decreases, the force on the support spring 63 also decreases. Therefore, under the condition that the elastic force of the support spring 63 is constant, the elastic force of the support spring 63 will push the anti-leakage component 62 to move inward toward the inside of the orifice cover 61, making the blockage of the oil return hole 53 more tight. Thus, the essential oil inside the liquid storage bottle 32 will not leak out, achieving the purpose of preventing leakage of the essential oil. The upper cover 22 and the pressure cap 4 are connected by threads to maintain the connection stability between the upper cover 22 and the pressure cap 4. Thus, the limiting plate 44 can maintain the limiting position of the orifice cover 61, making the anti-leakage mechanism 6 a complete whole. According to the support spring 63 of different materials and sizes, the material and structure of the support spring 63 are determined by calculating the spring constant. Based on Hooke's Law, the formula is F = k * x. It is calculated that the initial support spring 63 requires a force of 0.063N to compress 1mm. Then, by adjusting the compression of the support spring 63 through the gap between the anti-leakage component 62 and the orifice cover 61, it is found that the support spring 63 can withstand a force of 0.023N. Using the gravity formula G=mg, the mass of the leak-proof component 62 when the machine is aligned is calculated to be 2.42g. Using V=M / P, the density of the leak-proof component 62 under the condition of phase volume is calculated, so as to select the material with the appropriate density.

[0052] .

[0053] To provide atomizing gas, for example, such as Figure 3 As shown, air pumps 31 for providing air supply are installed on the lower ends of the outer walls on both sides of the main frame 3. A gas pipeline 34 is interference-fitted to the exhaust end of the air pump 31. The other end of the gas pipeline 34 is interference-fitted to the inside of the air inlet 42. The air pump 31 is connected to the inside of the air inlet head 43 through the gas pipeline 34 and the air inlet 42.

[0054] During use, the air pump 31 ensures the supply of gas flow and pressure required during atomization, and provides gas to the air inlet head 43 through the air passage of the gas pipe 34 and the air inlet 42, thereby supplying gas to the atomizing core 52. A solenoid valve is provided on the outside of the gas pipe 34. When the user presses the control button 33 protruding from the outside of the outer shell 1, the device is turned on, which enables the air pumps 31 on both sides of the main frame 3 to start working. The solenoid valve is used to control the airflow. It can drive a single air pump 31 to work or two air pumps 31 to work simultaneously, so as to realize the discharge of a single atomized essential oil from the two mist outlets 23 or the simultaneous discharge of atomized essential oil from both sides.

[0055] When using this utility model, the user presses the control button 33 protruding from the outer side of the outer shell 1 to turn on the device. The air pumps 31 at the lower ends of the outer walls on both sides of the main frame 3 start to work and deliver gas into the device through the gas pipeline 34 and the air inlet 42. The solenoid valve on the outside of the gas pipeline 34 can control the airflow. The user can choose to have a single air pump 31 working to achieve single-sided misting, or have two air pumps 31 working simultaneously to achieve double-sided misting.

[0056] The airflow provided by the air pump 31 enters the interior of the cap 4 through the gas pipe 34 and the air inlet 42. Then, it flows into the airflow channel 51 of the atomizing bracket 5 through the air inlet head 43, and finally impacts the atomizing core 52. The airflow impact causes a negative pressure to form inside the liquid storage bottle 32, while a high pressure is formed inside the first atomizing chamber 45. This pressure difference causes the leak-proof component 62 to squeeze the support spring 63, increasing the gap between the leak-proof component 62 and the orifice cap 61. The gas in the first atomizing chamber 45 enters the liquid storage bottle 32 through the oil return hole 53 and the gap to balance the air pressure. At the same time, the atomizing core 52 draws essential oil from the liquid storage bottle 32 through the oil suction pipe 54 and atomizes it.

[0057] After atomization, the essential oil particles enter the first atomization chamber 45 for initial screening. Large atomized essential oil particles are guided to converge into the oil return hole 53 by the conical inner wall of the atomization cover 41. The finer atomized particles after initial screening enter the second atomization chamber 46 for secondary screening to further refine the particles. Finally, the screened atomized particles are discharged into the environment through the mist outlets 23 on both sides of the top cover 22.

[0058] The large particles of essential oil and liquid essential oil that gather at the oil return hole 53, under the combined action of their own weight and air pressure, squeeze the leak-proof part 62, further increasing the gap between it and the hole cover 61. The essential oil flows back to the liquid storage bottle 32 through the oil return hole 53 through this gap, realizing recycling.

[0059] When the device is tilted, the force of gravity on the leak-proof component 62 is decomposed, and the component force along the direction of the support spring 63 becomes smaller. The elastic force of the support spring 63 pushes the leak-proof component 62 to move inward toward the hole cover 61, tightly blocking the oil return hole 53 and preventing the essential oil in the liquid storage bottle 32 from leaking.
