Description

Technical Field

[0001] The utility model belongs to the technical field of atomizing devices, and in particular relates to an atomizing device. Background Art

[0002] In aromatherapy or incense, a device that atomizes and diffuses essential oils is usually used to diffuse the fragrance, so that the fragrance of the essential oils can quickly spread to the indoor environment of the user, thereby achieving the effect of making the user physically and mentally happy. In aromatherapy or incense, fragrance is an important choice; generally speaking, different fragrances are used at different times or for different desired effects. The fragrance depends entirely on the essential oils used in the aromatherapy process. Different essential oils emit different fragrances after or without atomization.

[0003] The fragrance of the aromatherapy machine mainly uses an air pump to atomize the essential oil in the essential oil bottle through the atomizer core to become aerosol and spread indoors, making the room full of fragrance. The existing atomizer core is usually composed of multiple accessories and has a certain size and volume. If a miniature aromatherapy machine is to be produced, the size of the existing atomizer core is not suitable. Therefore, there are some small atomizer cores with simple structures on the market, but the existing atomizer cores are independent components and need to be installed in the aromatherapy machine before use. First, the internal structure of the aromatherapy machine is complicated. Second, the strength of the existing atomizer core is insufficient. When it is assembled into the aromatherapy machine, it is a tight fit, and the assembly force is relatively large, which is easy to deform the hedging slope and the air outlet and liquid outlet are compressed and twisted, resulting in failure to atomize and discharge mist; in addition, the existing aromatherapy machine has no anti-backflow structure for the pipeline for outflowing atomized gas, which leads to the problem of liquid leaking out of the pipeline when the aromatherapy machine is tilted, as shown in the previously disclosed CN215916036U and CN215902012U.

[0005] In the first aspect, in order to solve the above-mentioned technical problems, the utility model provides an atomization device, comprising a bottle body for accommodating liquid, a cover body covered on the bottle body and an air pump arranged in the cover body, the cover body is provided with a vertically arranged atomization tube, an atomization chamber is arranged in the atomization tube, one side of the atomization tube is provided with an air inlet hole connecting the air pump and the atomization chamber in the horizontal direction, the bottom of the atomization chamber is provided with a liquid outlet hole located on one side of the air inlet hole in the longitudinal direction, the lower end of the liquid outlet hole is provided with a straw extending downward to the inside of the bottle body, the bottom of the atomization chamber is also provided with a reflux hole connected to the internal space of the bottle body, and a one-way valve is provided in the reflux hole.

[0006] Furthermore, the air inlet is connected to the air outlet of the air pump through an air pipe.

[0007] Furthermore, a joint arranged around the air inlet hole is provided along a lateral protrusion on one side of the atomizing tube, an air inlet passage communicating with the air inlet hole is provided in the middle of the joint, and one end of the air pipe is sleeved on the joint.

[0008] Furthermore, the bottom protrusion of the atomizing chamber is provided with a boss located in front of the air inlet hole, the lower end of the boss is provided with a liquid inlet channel for inserting the straw, and the middle of the upper end of the boss is provided with the liquid outlet hole connecting the liquid inlet channel and the atomizing chamber.

[0009] Furthermore, a counter-inclined surface is provided on one side of the boss facing the air inlet, and a gap is provided between the counter-inclined surface and the air inlet.

[0010] Furthermore, the upper end surface of the boss is an opposing atomization slope facing away from the air inlet, and the angle between the opposing atomization slope and the horizontal plane is 105-110 degrees.

[0011] Furthermore, the one-way valve includes a valve cover located below the reflux hole and a valve column arranged in the middle of the upper end of the valve cover.

[0012] Furthermore, a buckle is provided on one side of the upper end of the valve column and is engaged with the upper end of the reflux hole, and a vertical distance between the buckle and the valve cover is greater than an axial length of the reflux hole.

[0028] In order to more fully understand the technical content of the present invention, the present invention will be further introduced and explained in conjunction with the accompanying drawings and specific embodiments below; it should be noted that descriptions such as "first" and "second" in the text are used to distinguish different components, etc., and do not represent the order of precedence, nor do they limit the "first" and "second" to different types.

[0029] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0030] Example

[0031] like Figures 1 to 6 As shown, the atomizing device shown in this embodiment includes a bottle body 1 for accommodating liquid, a cover body 2 covered on the bottle body 1, and an air pump 3 arranged in the cover body 2. A vertically arranged atomizing tube 20 is arranged on the cover body 2, and an atomizing chamber 21 is arranged in the atomizing tube 20. An air inlet 22 connecting the air pump 3 and the atomizing chamber 21 is arranged in a horizontal direction on one side of the atomizing tube 20, that is, the gas generated by the air pump 3 is introduced into the atomizing chamber 21 through the air inlet 22 to atomize the liquid. A liquid outlet 23 located on one side of the air inlet 22 is arranged in a longitudinal direction at the bottom of the atomizing chamber 21, and the lower end of the liquid outlet 23 is provided with a liquid outlet 23. A straw 4 is provided which extends downward to the bottom of the bottle body 1, that is, the straw 4 is used to suck the liquid upward and then spray it out from the liquid outlet; the air inlet 22 and the liquid outlet 23 are arranged adjacent to each other and perpendicular to each other, that is, the gas sprayed through the air inlet 22 intersects with the liquid sprayed through the liquid outlet 23, so that the sprayed liquid can be atomized by the sprayed high-pressure gas; a reflux hole 24 connected to the internal space of the bottle body 1 is also provided at the bottom of the atomization chamber 21, so that the condensed liquid in the atomization chamber can flow back into the bottle body after atomization, and a one-way valve 5 is provided in the reflux hole 24 to prevent the liquid in the bottle body from flowing into the atomization chamber.

[0032] In the above, firstly, an atomizing tube and an atomizing chamber are added to the cover body, and liquid outlet holes and air inlet holes opened in the longitudinal and transverse directions are directly arranged on the atomizing tube, which have the same effect as the atomizing core, that is, the liquid inside the bottle body is sucked up by a straw and sprayed out from the liquid outlet hole, and the sprayed liquid is atomized by the high-pressure gas at the air inlet hole. By integrating the atomizing structure directly on the cover body, the use of the atomizing core is reduced, thereby simplifying the internal structure of the aromatherapy machine, and avoiding the problem of deformation of the atomizing core resulting in failure to atomize when installing a traditional atomizing core.

[0033] Secondly, a reflux hole is added at the bottom of the atomization chamber. Firstly, it is convenient for the condensed liquid after atomization to flow back into the bottle body, and secondly, it is to maintain the air flow in the bottle body. In order to avoid the problem that the liquid in the bottle body flows into the atomization chamber through the reflux hole and causes outflow and leakage, a one-way valve is added in the reflux hole, so that the liquid can only flow into the bottle body from the atomization chamber, but cannot flow outward from the bottle body into the atomization chamber, thereby avoiding the problem that the liquid in the bottle body flows outward and leaks when the aromatherapy machine is tipped over.

[0034] In one embodiment, if Figures 4 to 5 As shown, the air inlet 22 is connected with the air outlet of the air pump 3 through the air pipe 6; preferably, in order to achieve the connection with the air pipe 6, a joint 25 arranged around the air inlet 22 is provided along a lateral protrusion on one side of the atomizing tube 20, and an air inlet channel 26 connected with the air inlet 22 and the air pipe 6 is provided in the middle of the joint 25; one end of the air pipe 6 is sleeved on the joint 25, and the other end is sleeved on the air outlet of the air pump; specifically, the aperture of the air inlet 22 is smaller than the aperture of the air inlet channel 26 to increase the ejection pressure of the gas.

[0035] In one embodiment, if Figures 4 to 5 As shown, the bottom of the atomizing chamber 21 is provided with a boss 27 located in front of the air inlet hole 22, the lower end of the boss 27 is provided with a liquid inlet channel 28, the upper end of the suction tube 4 is inserted into the liquid inlet channel 28, and the middle of the upper end of the boss 27 is provided with a liquid outlet hole 23 connecting the liquid inlet channel 28 and the atomizing chamber 21. The aperture of the liquid outlet hole 23 is smaller than the aperture of the liquid inlet channel 28 to increase the spraying pressure of the liquid.

[0036] In a specific implementation case, the atomization tube and the cover body are manufactured by integral molding, that is, the atomization structure on the atomization tube is directly integrated on the cover body by integral molding.

[0037] In one embodiment, if Figure 5 As shown, a counter-slope 271 is provided on one side of the boss 27 facing the air inlet 22, and the upper end face of the boss 27 is a counter-slope 272 arranged opposite to the air inlet 22, and a gap is provided between the counter-slope 271 and the air inlet 22. Since a certain angle is formed between the counter-slope 271 and the air inlet 22, the gas in the air inlet 22 can present a strong air pressure, and a part of the air volume transported outward by the air inlet 22 will change the flow direction, so that wind forces in different directions act on the counter-slope 272 at the liquid outlet 23 at the same time, so that the liquid (such as essential oil) flowing out of the liquid outlet 23 can be more comprehensively broken up and atomized by strong winds in different directions and angles to form uniform and fine tiny particles, and a part of the gas whose flow direction is changed by the counter-slope 271 is close to the edge of the liquid outlet, so that oil accumulation is not easy to occur on the edge.

[0038] It is understandable that the vertical projection of the boss on the vertical plane overlaps with at least part of the air inlet holes, and at least part of the air inlet holes do not overlap with the vertical projection of the boss; it is generally preferred that the overlapping and non-overlapping areas are each half of the air inlet holes.

[0039] In one embodiment, the angle between the atomization slope 272 and the horizontal plane is 105-110 degrees. The inclination angle of the slope is coordinated with the air inlet 22 to avoid eddy blockage at the microscopic level, and the angle of 105 to 110 degrees can accurately control the atomization particle size within 1 to 100 microns. The adjustment of the atomization particle size plays a role in selecting fragrance molecules of different particle sizes.

[0040] In one embodiment, if Figures 5 to 8 As shown, the one-way valve 5 includes a valve cover 51 located below the reflux hole 24 and a valve column 52 arranged in the middle of the upper end of the valve cover 51. The outer diameter of the valve cover 51 is larger than the aperture of the reflux hole 24. Therefore, when the atomizing device is used, the pressure of the liquid can be used to make the valve cover 51 close to the cover body 2 and close the reflux hole 24. The valve column 52 is inserted into the reflux hole 24 and is connected to the reflux hole 24 by snapping. A reflux gap 29 is provided between the valve column 52 and the reflux hole 24 for the condensed liquid in the atomizing chamber 21 to flow back into the bottle body 1.

[0041] As a preference, Figures 5 to 8 As shown, a protrusion is provided on one side of the upper end of the valve column 52 with a buckle 53 which is engaged with the upper end of the reflux hole 24, and the vertical distance between the buckle 53 and the valve cover 51 is greater than the axial length of the reflux hole 24, so that the one-way valve 5 can slide up and down in the reflux hole 24. When the atomizer is placed upright, the one-way valve 5 moves downward under the action of gravity, so that the valve cover 51 is away from the bottom of the cover body to open the reflux hole and the reflux gap.

[0042] Preferably, the bottom of the valve cover 51 is a spherical surface with a downward protrusion in the middle, that is, the valve cover 51 has the ability to deform upward, so that when the atomizing device is inverted, the deformation characteristics of the valve cover can be used to improve the sealing performance of the valve cover to the reflux hole.

[0043] In one embodiment, if Figures 1 to 5 As shown, in order to realize the integrated molding of the atomizing tube and the cover body, the upper end of the atomizing tube is designed to be an open structure, so that an upper cover 7 covering the opening is provided at the upper end of the atomizing tube 20, and a mist outlet channel 71 connected to the atomizing chamber 21 is provided in the middle of the upper cover 7 to facilitate the output of the atomized particles to the outside; in this structure, when gas is input through the air pump, the pressure in the bottle increases, so that the pressure difference is utilized to make the liquid in the bottle go up along the straw and then spray out from the liquid outlet hole, and finally be atomized into particles by the gas sprayed from the air inlet hole and then output out through the mist outlet channel.

[0044] In a specific implementation case, the particle size of the droplets can be controlled by controlling factors such as air flow velocity, liquid injection velocity and surface tension to form a uniform and fine mist particle structure.

[0045] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used in this article to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as a limitation on the present invention.
