[0027] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] Reference Figures 1 to 4 The utility model proposes an atomization module capable of changing the flow rate of a fluid, comprising a shell 1, wherein an atomization chamber 11 communicating with the outside is formed inside the shell 1, an atomization sheet 12 is arranged in the atomization chamber 11, the shell 1 is further provided with a mounting portion 13 for connecting an external liquid-containing bottle 2, a liquid-conducting channel 14 is provided between the mounting portion 13 and the atomization chamber 11, a liquid-conducting member 3 is arranged in the liquid-conducting channel 14, the liquid-conducting member 3 is arranged in the liquid-conducting channel 14 with interference fit or transition fit, the liquid-conducting member 3 has a first end 31 and a second end 32, the first end 31 is connected to the mounting portion 13, the second end 32 abuts against the atomization sheet 12, a liquid-conducting hole 33 is formed through the liquid-conducting member 3 from the first end 31 to the second end 32, a siphon groove 34 is further provided at the second end 32, the siphon groove 34 is communicated with the liquid-conducting hole 33, when the liquid fills the siphon groove 34, the liquid in the liquid-containing bottle 2 stops dripping.

[0029] It can be understood that the atomization chamber 11 is a space for atomizing the essential oil, and the atomization sheet 12 is arranged in the atomization chamber 11. Furthermore, the atomization chamber 11 can also be provided with a structure such as an electronic control mainboard, a power supply line, etc. for controlling the atomization sheet 12. The shell 1 is also provided with a mounting portion 13 connected to the external liquid bottle 2. The mounting portion 13 can be connected to the external liquid bottle 2 by means of a threaded connection, a snap connection, a transition fit, etc., which are not limited here. The mounting portion 13 is connected to the atomization chamber 11 through a liquid guide channel 14, and the essential oil can enter the atomization sheet 12 inside the atomization chamber 11 through this channel for atomization; the atomization chamber 11 is connected to the outside world, and at least an air inlet and a mist outlet are opened to the outside world to form a channel for gas circulation, so as to continuously bring the atomized essential oil molecules out of the shell 1.

[0030] In the process of the essential oil in the liquid bottle 2 flowing from the mounting portion 13 to the atomizing sheet 12, the liquid is guided through the liquid guiding member 3. The liquid guiding member 3 is arranged in the liquid guiding channel 14 with an interference fit or transition fit. On the one hand, it can have a certain fixing effect on the liquid guiding member 3 to prevent it from shaking inside the shell 1 and affecting the dripping of the essential oil. On the other hand, it can also prevent the essential oil from entering the fitting surface of the liquid guiding member 3 and the liquid guiding channel 14 from the connection between the liquid guiding member 3 and the mounting portion 13 to a certain extent.

[0031] The liquid guiding member 3 is a columnar structure, with a first end 31 connected to the mounting portion 13 and in contact with the essential oil in the liquid holding bottle 2, and a second end 32 abutting against the atomizing sheet 12. It should be noted that the liquid guiding member 3 is made of a porous microporous material, and the essential oil flows from the first end 31 to the second end 32 along the countless micropores in the liquid guiding member 3, so that the essential oil does not flow down too fast. The liquid guiding member 3 is provided with a liquid guiding hole 33 from the first end 31 to the second end 32, so that the essential oil in the liquid holding bottle 2 can flow smoothly to the surface of the atomizing sheet 12.

[0032] In order to further control the dripping process of the liquid, a siphon groove 34 is also provided at the second end 32 of the liquid guiding member 3. The siphon groove 34 is formed by a depression of a part of the end surface of the second end 32 and is connected with the liquid guiding hole 33. When the essential oil fills the siphon groove 34, there is no air between the siphon groove 34 and the liquid guiding hole 33, and the essential oil in the liquid holding bottle 2 stops dripping into the siphon groove 34; when the atomizing sheet 12 atomizes part of the essential oil until the essential oil does not fill the siphon groove 34, air continues to flow between the siphon groove 34 and the liquid guiding hole 33, and the essential oil in the liquid holding bottle 2 will continue to drip into the siphon groove 34 through the siphon action.

[0033] Since the liquid guiding member 3 is placed vertically and its two ends are respectively connected to the liquid holding bottle 2 and the atomizing sheet 12, it has a long liquid guiding distance, which also forms a large pressure difference at both ends of the liquid guiding member 3. The greater the pressure difference, the better the siphon effect, making the dripping of the essential oil smoother and more even, and there will be no intermittent dripping due to the small pressure difference; and the essential oil in the liquid holding bottle 2 flows directly to the surface of the atomizing sheet 12 through the liquid guiding member 3, which greatly reduces the risk of bubbles forming between the liquid guiding channel 14 and the liquid guiding member 3, making the essential oil drip more smoothly, thereby making the mist sprayed by the product more even and delicate.

[0034] Reference Figure 4 In one embodiment of the present application, a portion of the edge of the siphon groove 34 and the end surface of the second end 32 form a step line 341 , the step line 341 is arc-shaped, and the step line 341 passes through the liquid guide hole 33 .

[0035] It can be understood that the cross-section of the siphon groove 34 is an arc-shaped structure, and the arc-shaped edge is conducive to the essential oil flowing along the edge to fill the siphon groove 34, and the liquid guide hole 33 is located on the edge line, so that the liquid guide hole 33 is just connected to the siphon groove 34, and a siphon effect can be formed to guide the essential oil from the liquid bottle 2 into the siphon groove 34.

[0036] In this example, the cross-sectional area of ​​the siphon groove 34 is less than half of the area of ​​the end surface of the liquid guide member 3 in order to allow the essential oil to drip in an appropriate amount. If the siphon groove 34 is too small, a small amount of essential oil will fill the entire siphon groove 34, and may not even be enough for a single atomization of the smallest unit of the atomizer sheet 12; if the siphon groove 34 is too large, more essential oil will be needed to prevent the liquid from continuing to drip, and the essential oil may overflow from the atomizer sheet 12 and affect the overall atomization work.

[0037] Reference Figures 1 to 2 In one embodiment of the present application, the projection of the liquid guide member 3 on the atomizer sheet 12 is offset from the center of the atomizer sheet 12 .

[0038] It can be understood that since the place on the atomizer sheet 12 where the atomization effect is fastest is the center of the atomizer sheet 12, in this example, the liquid guide member 3 is deliberately offset from the center of the atomizer sheet 12 to avoid covering the center of the atomizer sheet 12 and affecting the atomization effect; further, the siphon groove 34 can be located on the side of the liquid guide member 3 close to the center of the atomizer sheet 12, so that the essential oil dripping can quickly contact the center of the atomizer sheet 12, thereby improving the atomization effect of the essential oil.

[0039] Reference Figures 3 to 4 In one embodiment of the present application, the liquid guiding member 3 is a columnar structure, and its cross section is circular, elliptical or polygonal. Correspondingly, the cross section of the liquid guiding channel 14 is circular, elliptical or polygonal.

[0040] It can be understood that in this example, the liquid guiding member 3 is a cylindrical structure. The cylindrical liquid guiding member 3 and the liquid guiding channel 14 can make the contact surface of the two be subjected to relatively uniform force, and the friction force is evenly distributed on the surface of the cylinder, so that the two are not easy to loosen or relatively displaced; and the cylindrical design also makes the two easy to install and more convenient; the cross-section of the liquid guiding member 3 is circular, and the liquid is evenly absorbed. The liquid can be evenly sucked in from all directions, ensuring the efficiency and uniformity of the liquid absorption, so that the dripping of the essential oil is smoother and more uniform.

[0041] Reference Figure 1 In one embodiment of the present application, a spring cavity 141 is formed on a portion of the inner wall of the liquid guiding channel 14 , a spring 142 is disposed in the spring cavity 141 , and the spring 142 abuts against the liquid guiding member 3 .

[0042] It can be understood that the setting of the spring 142 can keep the liquid guide member 3 against the atomizer plate 12 at all times, which facilitates the essential oil to drip onto the atomizer plate 12, while also preventing the liquid guide member 3 from shaking and affecting the dripping process of the essential oil.

[0043] Reference Figures 3 to 4 In one embodiment of the present application, the liquid-conducting member 3 is made of porous ceramic or oil-conducting cotton or foamed silicone.

[0044] It can be understood that porous ceramics, oil-conducting cotton, and foamed silicone are all materials with porous microporous structures inside, and essential oil molecules can flow along their internal micropores. In the actual production process, the selection can be made based on the essential oil flow rate, material strength, and manufacturing cost. In this example, porous ceramics are preferably used to make the liquid-conducting part 3, which has a certain structural rigidity, is not easy to damage, and helps to save costs.

[0045] Reference Figures 5 to 8 The present application also proposes a fragrance diffuser, which is provided with the above-mentioned atomization module that can change the flow rate of the fluid. The fragrance diffuser can have one, two or three atomization modules, and the atomization module can be detachably inserted into the fragrance diffuser. The fragrance diffuser can be a structure placed on a desktop or a structure plugged into a socket on the wall. An electronic control mainboard, indicator lights and other structures can also be arranged in the fragrance diffuser according to needs to facilitate user use.

[0046] The technical solution of the utility model has a long liquid guiding distance by arranging a liquid guiding piece 3 at both ends of the shell body 1 respectively connecting the liquid holding bottle 2 and the atomizing piece 12, so that a large pressure difference is formed at both ends of the liquid guiding piece 3. The greater the pressure difference, the better the siphon effect will be, so that the dripping of the essential oil will be smoother and more uniform, and there will be no intermittent dripping due to the small pressure difference; and the essential oil in the liquid holding bottle 2 directly flows to the surface of the atomizing piece 12 through the liquid guiding piece 3, which greatly reduces the risk of bubbles forming between the liquid guiding channel 14 and the liquid guiding piece 3, so that the essential oil drips more smoothly, thereby making the mist sprayed by the product more uniform and delicate.
