This application claims priority to Chinese Application No. 201820876699.1, filed on Jun. 7, 2018, the contents of which are incorporated herein by reference in their entirety.
The present disclosure relates to the field of aromatherapy equipment, in particular to an atomization apparatus.
Aromatherapy machine is an aromatherapy equipment, which generally uses high-frequency oscillation such as ultrasonic vibration to atomize water mixed with an essential oil and release it into the air to make the air full of fragrance. The existing aromatherapy machine generally uses the method of dripping oil to add the essential oil to the water at one time. As a result, the concentration of the fragrance released by the aromatherapy machine becomes less and less over time, and the customer's experience is poor. In order to enhance the customer's experience, there is also a way of continuously supplying essential oil. An oil cup containing an essential oil can be disposed in the aromatherapy machine, and the oil cup can continuously supply the essential oil to the water to reduce the fluctuation of the fragrance concentration. However, in this way, the water droplets in the atomized vapor easily drop into the oil cup, which affects the purity of the essential oil and is not conducive to the maintenance of the fragrance concentration.
An atomization apparatus is provided in the present disclosure, which can reduce the influence of water droplets and water mist on the concentration of essential oil in the oil cup, and can ensure that the concentration of the essential oil is constant. The atomization apparatus may utilize the principle of water-oil balance to continuously and stably provide the fragrance. The present disclosure adopts the following technical solutions.

In order to explain the technical problems, the technical solutions, and the technical effects in the present disclosure more clearly, the technical solutions of the present disclosure will be further described below with reference to the accompanying drawings.
As shown in
The atomization apparatus also includes an atomizing component, which may be an atomizing sheet. The atomizing sheet may atomize the liquid in the reservoir chamber 21. The body is also provided with a nozzle 51 communicated with the internal cavity. When the atomization apparatus is in operation, the atomizing sheet atomizes the liquid in the internal cavity, and the atomized gas is discharged outward through the nozzle 51.
When using the atomization apparatus, it may be needed to add a liquid such as water to the reservoir chamber 21 in advance, and the level of the liquid should not be lower than the opening at the bottom of the oil cup 4. Then the essential oil may be added to the oil cup 4 through the opening at the upper end of the oil cup 4 so as to ensure that the level of the essential oil in the oil cup 4 is higher than the level of the liquid in the internal cavity. Since the compatibility of the essential oil with water is relatively low, the essential oil does not dissolve in the water. With the consumption of liquid in the reservoir chamber 21, there is a certain pressure difference between the essential oil and the liquid in the reservoir chamber 21. Under the pressure difference, the essential oil in the oil cup 4 flows into the reservoir chamber 21 from the opening at the lower end of the oil cup 4 until the pressure at the contact surface is balanced. Based on the relatively low compatibility between the essential oil and the water, and the principle of liquid pressure balance, the purpose of continuously supplying the essential oil into the reservoir chamber 21 is achieved, and the fluctuation of the concentration of the essential oil in the water is reduced, so that the fragrance of the atomized gas remains stable and the user experience is improved.
When the liquid in the reservoir chamber 21 is atomized, the atomized gas condenses into droplets on the top wall of the internal cavity and fall down. Thus, in order to prevent the liquid from dripping into the oil cup 4, the atomization apparatus is provided with a spacer 31. The spacer 31 prevents the dripping of a liquid water formed by the condense of water vapor from the reservoir chamber that may affect the concentration of the essential oil, and ensures that the concentration of the essential oil in the oil cup 4 does not substantially change. Specifically, the spacer 31 is disposed above the reservoir chamber 21 and forms an atomized gas passage with the internal top wall of the internal cavity. The atomized gas passage communicates with the nozzle 51 on the body, and the atomized gas is discharged through the atomized gas passage and the nozzle 51. On the one hand, the spacer 31 prevents the dripping of a liquid water formed by the condense of water vapor from the reservoir chamber that may affect the concentration of the essential oil. On the other hand, the spacer 31 may guide the atomized gas.
When the atomization apparatus is working normally, the atomized gas is sprayed out of the nozzle 51 through the atomized gas passage under the guidance of the spacer. The droplets condensed by the atomized gas in the atomized gas passage are attached to the side wall of the spacer 31, and then slide into the reservoir chamber 21 along the side wall of the spacer 31, thereby reducing the noise caused by the droplets in the atomized gas passage falling directly into the reservoir chamber 21. The oil cup 4 is located outside the atomized gas passage and is located outside a projection of the atomized gas passage onto the bottom of the internal cavity, and the spacer 31 may prevent the liquid in the atomized gas from dripping into the oil cup 4. In addition, the concentration of the essential oil in the oil cup 4 is kept constant, and the principle of water-oil balance is used to allow the atomization apparatus to continuously and stably provide the fragrance.
In this embodiment, the spacer 31 may extend downwardly from an internal top wall of the internal cavity to form a baffle, which is enclosed peripherally with an opening on a bottom of the baffle. The baffle may be an annular cylindrical structure, and the atomized gas flows from the internal hole of the cylindrical structure to the nozzle 51 under the guidance of the spacer 31 of the cylindrical structure. In order to further prevent the water mist or water droplets in the atomized gas from affecting the concentration of the essential oil in the oil cup 4, a plane on which the bottom end of the baffle is located may be lower than a plane on which the top end of the oil cup is located, which may achieve a better effect of the separation of the essential oil from the water mist or water droplets.
In order to allow the atomized gas in the internal cavity to enter the atomized gas passage formed by the spacer 31 and the internal wall of the internal cavity, there may a preset distance between the bottom of the spacer 31 and the liquid level of the reservoir chamber 21, so as to allow the gas outside the spacer 31 to enter the atomized gas passage. Optionally, the preset distance between the bottom end of the spacer 31 and the liquid surface may vary between 3-5 mm.
In some embodiments, the spacer 31 may be a non-enclosed plate-like structure, such as a flat plate or a curved plate, which may divide the internal cavity into two parts. The flat or curved plate forms an atomized gas passage with the top and a portion of the sidewall of the internal cavity. The oil cup 4 and the atomized gas passage are respectively located on both sides of the flat plate or the curved plate. In this manner, it is also possible to prevent the liquid droplets from falling into the oil cup 4, thereby ensuring the stability of the concentration of the essential oil in the oil cup 4.
In this embodiment, a muffling component 6 is disposed in the internal cavity, and a muffling component 6 is disposed at an upper end of a central axis of the atomizing sheet and is internally located relative to a flanking side of the spacer 31. The lower end of the muffling component 6 is immersed in the liquid, and the muffling component 6 reduces the sound of the water droplets falling on the water surface during the atomization, and the muffling component 6 has a guidance effect on the fallen water droplets, and thus the noise is reduced. As shown in
As shown in
In this embodiment, the muffling component 6 may also act as a guide for the atomized gas, and after the mist is guided through the muffling component 6, it is discharged by the nozzle 51. In addition, by setting spacer 31, the atomized gas in the spacer 31 moves upwards to contact the spacer 31, and the liquid in the atomized gas condenses and slides down into the water along the spacer 31. Secondary noise reduction may be achieved with the use of the muffling component 6. The noise of the atomization apparatus may be further reduced and the user experience may be improved.
In this embodiment, as shown in
In this embodiment, by setting the trough body 2 and the lower casing 1 as detachably connected, rather than arranging the trough body 2 and the lower casing 1 in a one-piece structure, when the trough body 2 needs to be cleaned, the trough body 2 can be removed from the lower casing 1 and individually cleaned, thus avoiding contact between water and the electrical component 7 between the lower casing 1 and the trough body 2, thereby ensuring the safety of the electrical component 7. This makes it convenient to clean the trough body 2 and reduces the failure rate of the atomization apparatus.
For easy disassembly, the trough body 2 and the lower casing 1 may be fixed by snapping. Specifically, the outer side of the bottom body of the trough body 2 is provided with a plurality of first engaging parts, and the positions of the lower casing 1 corresponding to the first engaging parts are respectively provided with the second engaging parts structurally matching with the first engaging parts. The trough body 2 can be attached to the lower casing 1 by engaging the first engaging parts and the second engaging parts. In some embodiments, a first engaging part may be a cylinder, and the corresponding second engaging part may be a hollow cylinder. The cylinder may be inserted into the internal hole of the cylinder to fix the trough body 2 and the lower casing 1. In other embodiments, the first engaging part may be a hollow body, and correspondingly, the second engaging parts may be a cylinder. The fixation of the trough body 2 and the lower casing 1 may be achieved.
As shown in
The bottom plate of the trough body 2 is provided with a through hole 24 which is located inside a projection of the nozzle 51 onto the bottom plate of the trough body 2, and an atomizing sheet is disposed in the through hole 24, which makes it convenient for the atomized gas generated by the atomizing sheet to directly enter the atomized gas passage.
In this embodiment, the oil cup 4 includes an oil cup body and a flared fuel filler port. The oil cup body is connected to the end of the flare fuel filler port. By setting the flared fuel filler port, it is convenient for the user to drip the essential oil into the oil cup 4. The oil cup 4 may also be provided with a tick mark, and the maximum scale is disposed at the upper end, for example, the connection of the flared fuel filler port and the oil cup body, to facilitate identification of the loaded essential oil capacity. Alternatively, the oil cup 4 may also have other shapes, such as cube tubes, tapered tubes, and the like.
In this embodiment, the cross-sectional area of the oil cup body is substantially the same, which may ensure that the amount of the essential oil added to the reservoir chamber 21 by the oil cup 4 is constant. This may be advantageous for maintaining the aroma concentration of the atomization apparatus to be stable.
Alternatively, the oil cup 4 may be integrally formed with the body or may be disposed independently of the body. When the oil cup 4 is integrally formed with the body, in order to facilitate the addition of the essential oil to the oil cup 4, the oil storage pipe 4 may be integrally provided with the trough body 2, and the bottom end of the oil cup 4 is provided with an oil hole so that the essential oil in the oil cup 4 is added to the reservoir chamber 21 through the oil hole. In order to reduce the residual oil in the oil cup 4, the oil outlet may extend upward along the bottom of the side wall of the oil cup 4, which may ensure that the essential oil at the bottom of the oil cup 4 can smoothly enter the reservoir chamber 21. The oil cup 4 may be integrated with the trough body 2, so the oil cup 4 does not need to be set alone. It is more convenient to use the atomization apparatus.
In this embodiment, the oil cup 4 is disposed independently of the body. Specifically, the fixing chamber 21 is further provided with a fixing device for fixing the oil cup 4, and the fixing device is located outside a projection of the spacer 31 onto the trough body. As shown in
The fixing base 23 is disposed at the side wall of the reservoir chamber 21 to prevent the oil cup 4 from affecting the atomization effect of the atomizing sheet located at the middle of the reservoir chamber 21, and the oil cup 4 is disposed at the side of the reservoir chamber 21. When the user adds the essential oil to the side of the position of the oil cup 4, the user's field of vision is relatively wide, and the user's line of sight may be substantially parallel with the scale line on the oil cup 4, so that the amount of the added essential oil is more accurate. In addition, the fixing base 23 is disposed at the side wall of the trough body 2 and is semi-cylindrical. When the oil cup 4 is removed, there is no hidden corner position in the trough body 2, which contributes to easy cleaning. In order to install the oil cup 4 to the fixing base 23, the bottom of the oil cup 4 is kept at a certain distance (for example, 4-5 mm) from the bottom surface of the reservoir chamber 21, and the bottom portion of the internal side wall of the fixing base 23 is also provided with a first snapping block 231 having a certain height. When the oil cup 4 is installed, the bottom of the oil cup 4 abuts the first snapping block 231 to ensure that the distance between the bottom end of the oil cup 4 and the bottom plate of the reservoir chamber 21 is set to allow the bottom of the oil cup 4 to communicate with the trough body 2.
In other embodiments, the fixing device may also be a fixing clip disposed on the side wall of the trough body 2, and the clip of the holder matches the shape of the oil cup 4. When fixing the oil cup 4 with the fixing clip, it is possible to set the distance between the bottom of the ensure oil cup 4 and the bottom plate of the trough body 2 by adjusting the position of the collet and the oil cup 4.
In order to ensure that the amount of the added essential oil matches the amount of water contained in the reservoir chamber 21, a protruded water level board 25 is also disposed in the reservoir chamber 21. The protruded water level board 25 may be provided with a scale. The scale may be configured to indicate a volume of a liquid contained in the reservoir chamber. When the water and the essential oil are added, the amount of addition may be accurately determined by the corresponding scale.
In this embodiment, the body further includes an upper casing 5, and the upper casing 5 and the lower casing 1 form an external housing of the atomization apparatus, and the upper casing 5 is disposed outside the upper cover 3 and the trough body 2, and covers the upper cover 3 and the trough body 2. The upper casing 5 is detachably connected to the upper cover 3, and when water or the essential oil needs to be added, the upper casing 5 is detached together with the upper cover 3. Specifically, as shown in
In order to maintain the air pressure balance in the atomization apparatus, as shown in
This embodiment provides an atomization apparatus, which is substantially similar to the atomization apparatus structure in Embodiment 1 and is different from Embodiment 1 in that, as shown in
In some embodiments, the isolation cover 36 may be integrally formed with the cavity wall of the internal cavity. For example, the isolation cover 36 may be a tubular structure having a lower end opening formed by extending downward from the internal wall of the upper cover 3, or the isolation cover 36 may be a cover having a lower end that is integrally formed with the trough body 2 or the upper cover 3. The isolation cover 36 may also be an independently provided cover that is fixed to the trough body 2 or the upper cover 3 by snapping or screwing.
In order to simplify the internal structure of the atomization apparatus, in this embodiment, the isolation cover 36 is integrally formed with the cavity wall of the internal cavity, as shown in
