Description

Technical Field

[0001] The invention relates to the technical field of atomizers. Background Art

[0002] The microporous membrane atomizer is a device that uses a microporous structure to disperse liquid into tiny droplets. It is widely used in the fields of medical treatment, cosmetics, pesticides, etc. Its working principle is to disperse the liquid into tiny droplets through the microporous structure to form a mist spray. This atomizer adopts microporous screen high-frequency oscillation technology. It consists of a ring-shaped piezoelectric ceramic sheet and a circular metal microporous membrane attached to the ceramic sheet, replacing the traditional ultrasonic atomization and airflow jet atomization methods. The advantage of the microporous atomizer is that it atomizes through tiny holes, avoiding the problems of large mist liquid particles and uneven dispersion when using traditional sprayers, and can provide more stable and efficient mist output.

[0003] However, due to the different solution media, the pore size of the circular metal microporous membrane is very small. The microporous membrane needs to be cleaned after use. Otherwise, the membrane micropores are very easy to be blocked and scale is generated, resulting in poor spray atomization effect, or the atomizer overheats, which has an adverse effect on the solution and affects the atomization effect. The existing atomizer has an integrated structure and a sealed internal space. It is not easy to clean and disassemble, which causes great trouble for maintenance. Summary of the invention

[0004] The purpose of the present invention is to solve the above technical problems and provide an atomizer with a replaceable nuclear pore membrane and an operating method.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

At this time, the liquid is adsorbed from the liquid storage cavity to the atomizing groove through the water pumping mechanism, and then the piezoelectric ceramic ring cooperates with the atomizing nucleus pore The diaphragm generates high-frequency vibrations, causing one side of the microporous umbrella-shaped expansion to repeatedly impact the liquid. The liquid flows faster through one side of the umbrella-shaped expansion and is sprayed out from the micropores to form atomization. After use, the lifting and lowering plate can be driven up by the displacement mechanism to complete the separation of the piezoelectric ceramic ring and the lifting and lowering plate from the atomization core pore diaphragm, so that the atomization core pore diaphragm can be easily replaced, which is convenient for the maintenance of the atomization core pore diaphragm. At the same time, it can also be replaced after the atomization of a specific liquid according to needs, avoiding blockage of the atomization core pore diaphragm and maintaining stable and efficient atomization output. At the same time, only the atomization core pore diaphragm needs to be replaced, and the maintenance cost is low, which is convenient for daily batch use.

[0008] Furthermore, a screw-on top cover is provided at the upper end of the liquid bin, and an atomization conduit is provided on the top cover and is arranged facing the middle of the atomization nucleus pore membrane.

The end of the high-density cotton core is in contact with the atomization core pore membrane, which is convenient for directly introducing the liquid into the atomization core pore membrane, thereby facilitating continuous atomization.

[0013] Through the above scheme, when the atomizing nucleus pore diaphragm needs to be replaced, the sleeve is rotated to rise, and then the slider is no longer squeezed downward by the sleeve, that is, the slider can move along the stroke groove, and the lifting and lowering plate can be lifted to complete the separation of the piezoelectric ceramic ring and the lifting and lowering plate from the atomizing nucleus pore diaphragm, so that the atomizing nucleus pore diaphragm can be conveniently replaced, and the new atomizing nucleus pore diaphragm is placed on the metal loading plate device, and the sleeve is rotated to descend, and the sleeve drives the slider to move downward along the stroke groove, and the slider drives the lifting and lowering plate to descend through the pull rod, and the arc-shaped groove on the lifting and lowering plate is embedded in the arc-shaped protrusion on the atomizing nucleus pore diaphragm, so that the lifting and lowering plate and the atomizing nucleus pore diaphragm are clamped and fixed, and the piezoelectric ceramic ring is connected to the lifting and lowering plate, which then causes the piezoelectric ceramic ring to be in close contact with the atomizing nucleus pore diaphragm, which is convenient for subsequent atomization, and the whole process is simple to operate.

[0014] Furthermore, a limiting protrusion is provided in the boss, the upper end of the water-drawing pipe extends from the boss, is wound around the limiting protrusion and then extends into the boss, the bottom end of the water-drawing pipe extends from the bottom end of the boss into the liquid storage cavity, and the limiting protrusion is located at the upper end of the sleeve moving track.

[0015] Through the above scheme, a limiting protrusion is set, that is, the water drawing pipe bypasses the limiting protrusion, and when the sleeve rises to the top, the limiting protrusion is squeezed, that is, the water drawing pipe is squeezed, the water flow delivery of the water drawing pipe is reduced, and the water seepage during the replacement of the atomization nuclear pore membrane is reduced, which facilitates the replacement operation.

The piezoelectric ceramic ring 17 is connected to the power supply. The atomizing groove 14 is provided with a clamping assembly adapted to the atomizing nucleus pore diaphragm 16. The clamping assembly includes a lifting and pressing plate 18 connected to the piezoelectric ceramic ring 17 in the atomizing groove 14. A displacement mechanism for causing the lifting and pressing plate 18 to move in a vertical direction is provided on the boss 12. A locking mechanism is provided between the lifting and pressing plate 18 and the atomizing nucleus pore diaphragm 16. The locking mechanism includes an arc-shaped protrusion 19 provided on the atomizing nucleus pore diaphragm 16, and an arc-shaped groove 20 is provided at a corresponding position on the lifting and pressing plate 18.

[0045] Therefore, a screw-on top cover 21 is provided. When the top cover 21 is screwed on and fixed, the atomizing conduit 22 faces the atomizing core hole diaphragm 16, which facilitates the atomizing airflow. When the atomizing core hole diaphragm 16 needs to be replaced, the top cover 21 can be unscrewed to facilitate the replacement operation. The clamping assembly is provided to facilitate clamping and fixing the atomizing nucleus pore diaphragm 16, that is, the lifting and lowering plate 18 is driven by the displacement mechanism to complete the vertical movement. When the lifting and lowering plate 18 descends, the arc-shaped groove 20 on the lifting and lowering plate 18 is embedded in the arc-shaped protrusion 19 on the atomizing nucleus pore diaphragm 16, so that the lifting and lowering plate 18 and the atomizing nucleus pore diaphragm 16 are clamped and fixed. At the same time, the piezoelectric ceramic ring 17 is connected to the lifting and lowering plate 18, and then the piezoelectric ceramic ring 17 is caused to be in close contact with the atomizing nucleus pore diaphragm 16, which is convenient for subsequent excitation of the piezoelectric ceramic ring 17, so that the atomizing nucleus pore diaphragm 16 generates high-frequency vibration. At this time, the liquid is adsorbed from the liquid storage cavity 13 to the atomizing groove 14 through the water-drawing mechanism, and then the piezoelectric ceramic ring 17 is matched with the piezoelectric ceramic ring 17. The atomizing nucleus pore diaphragm 16 generates high-frequency vibrations, which prompts the microporous umbrella-shaped expansion side to repeatedly impact the liquid. The liquid flows faster through the umbrella-shaped expansion side and is sprayed out from the micropores to form atomization. After use, the lifting and lowering plate 18 can be driven to rise by the displacement mechanism to complete the separation of the piezoelectric ceramic ring 17 and the lifting and lowering plate 18 from the atomizing nucleus pore diaphragm 16, so that the atomizing nucleus pore diaphragm 16 can be easily replaced, which is convenient for the maintenance of the atomizing nucleus pore diaphragm 16. At the same time, it can also be replaced after the atomization of a specific liquid according to needs, avoiding blockage of the atomizing nucleus pore diaphragm 16 and maintaining stable and efficient atomization output. At the same time, only the atomizing nucleus pore diaphragm 16 needs to be replaced, and the maintenance cost is low, which is convenient for daily batch use.

[0046] like Figure 1 and Figure 2 and Figure 3As shown, the displacement mechanism includes a stroke groove 24 vertically arranged on the outer edge of the boss 12, a slider 25 is arranged in the stroke groove 24, a pull rod 26 is arranged between the slider 25 and the lifting and pressing plate 18, and threads are distributed on the outer edge of the boss 12, and a sleeve 27 is screwed on the outer circumference of the thread, and the lower end of the sleeve 27 is in sliding contact with the slider 25. When the atomizing nucleus pore diaphragm 16 needs to be replaced, the sleeve 27 is rotated to rise, and then the slider 25 is no longer squeezed downward by the sleeve 27, that is, the slider 25 can move along the stroke groove 24, and the lifting and pressing plate 18 can be lifted, so as to complete the separation of the piezoelectric ceramic ring 17 and the lifting and pressing plate 18 from the atomizing nucleus pore diaphragm 16, that is, The atomizing nucleus pore diaphragm 16 can be replaced conveniently. A new atomizing nucleus pore diaphragm 16 is installed on the metal loading plate 15 and lowered by rotating the sleeve 27. The sleeve 27 drives the slider 25 to move downward along the stroke groove 24. The slider 25 drives the lifting and lowering plate 18 to lower through the pull rod 26. The arc groove 20 on the lifting and lowering plate 18 is embedded in the arc protrusion 19 on the atomizing nucleus pore diaphragm 16 to complete the clamping and fixing of the lifting and lowering plate 18 and the atomizing nucleus pore diaphragm 16. At the same time, the piezoelectric ceramic ring 17 is connected to the lifting and lowering plate 18, which then promotes the piezoelectric ceramic ring 17 to be in close contact with the atomizing nucleus pore diaphragm 16, which is convenient for subsequent atomization. The whole process is simple to operate.

The water-drawing pipe 23 is filled with a high-density cotton core. The end of the high-density cotton core is embedded in the metal loading plate 15 and abuts against the atomizing core pore membrane 16. The water-drawing pipe 23 is provided to facilitate carrying the high-density cotton core. The high-density cotton core is convenient for drawing liquid from the liquid storage chamber 13 to the atomizing groove 14. The end of the high-density cotton core abuts against the atomizing core pore membrane 16, so as to facilitate direct introduction of liquid into the atomizing core pore membrane 16 and facilitate continuous atomization.

[0048] In order to reduce the difficulty of replacing the atomization nucleus pore membrane 16, Figure 1 and Figure 2 and Figure 3 As shown, a limiting protrusion 28 is provided in the boss 12, the upper end of the water-drawing pipe 23 extends from the boss 12, is wound around the limiting protrusion 28, and then extends into the boss 12, and the lower end of the water-drawing pipe 23 extends from the lower end of the boss 12 into the liquid storage chamber 13, and the limiting protrusion 28 is located at the upper end of the moving trajectory of the sleeve 27. When the sleeve 27 moves to the uppermost end, the sleeve 27 will abut against the limiting protrusion 28 and squeeze the water-drawing pipe 23 wound around the outer periphery of the limiting protrusion 28, thereby reducing the water flow transport of the water-drawing pipe 23, reducing water seepage during replacement of the atomization nucleus pore diaphragm 16, and facilitating the replacement operation.

[0049] Operation process: Step S1, after a certain period of normal use, prepare to replace the atomizing nucleus pore membrane 16 according to the plan, and turn off the power;

[0050] Step S2, rotating the top cover 21, separating the top cover 21 and the atomizing conduit 22, emptying the residual liquid in the liquid storage cavity 13 and cleaning the liquid tank 11;

[0051] Step S3, the lifting and lowering plate 18 is caused to rise in the vertical direction by the displacement mechanism, specifically, the sleeve 27 is rotated, the slider 25 moves along the travel groove 24, and the lifting and lowering plate 18 is lifted upward, the lifting and lowering plate 18 is lifted upward, the arc groove 20 on the lifting and lowering plate 18 is separated from the arc protrusion 19 on the atomizing nucleus pore membrane 16, the sleeve 27 moves upward to the top, the sleeve 27 abuts against the limiting protrusion 28 and squeezes the water drawing pipe 23 arranged around the outer periphery of the limiting protrusion 28;

[0052] Step S4, removing the old atomizing nucleus pore membrane 16 and installing a new atomizing nucleus pore membrane 16;

[0053] Step S5, the lifting and pressing plate 18 is caused to descend in the vertical direction through the displacement mechanism, specifically: the sleeve 27 is rotated in the opposite direction, the slider 25 moves downward along the stroke groove 24, the lifting and pressing plate 18 descends, the arc groove 20 is engaged and fixed with the arc protrusion 19 on the atomizing nucleus pore diaphragm 16, and then the new solution is injected into the liquid storage chamber 13, and the top cover 21 is tightened to complete the replacement step, and the old atomizing nucleus pore diaphragms 16 are recycled and cleaned in batches.

[0054] Example 2

[0055] The structure of Example 2 is basically the same as that of Example 1, except that Figure 1 and Figure 4 and Figure 5 In Example 2, the displacement mechanism includes a stroke groove 24 vertically arranged on the boss 12, and a connecting rod 29 is arranged in the stroke groove 24. The upper end of the connecting rod 29 is fixed to the lifting and lowering plate 18, and a tensioning spring 30 is arranged on the periphery of the connecting rod 29. The tensioning spring 30 has a tendency to drive the connecting rod 29 to move downward. The lower end of the connecting rod 29 is provided with a driving mechanism for driving the connecting rod 29 to rise. In the working state, the tensioning spring 30 drives the connecting rod 29 to descend, prompting the piezoelectric ceramic ring 17 and the lifting and lowering plate 18 to press against the atomizing nucleus pore diaphragm 16, maintaining a pressed and fixed state, and facilitating atomization. When replacing and maintaining, the driving mechanism can be set to drive the connecting rod 29 to rise, and the piezoelectric ceramic ring 17 and the lifting and lowering plate 18 are separated from the atomizing nucleus pore diaphragm 16, so that the atomizing nucleus pore diaphragm 16 can be conveniently replaced.

[0056] Reference Figure 1 and Figure 4 and Figure 5The driving mechanism includes a magnet 31 arranged at the lower end of the connecting rod 29, the magnet 31 is slidably abutted against the stroke groove 24, and an electromagnet plate 32 connected to the power supply is arranged at the lower end of the boss 12 opposite to the magnet 31. For the convenience of operation, the electromagnet plate 32 is controlled and powered separately. Turning off the power supply of the atomizing component of the device does not affect the normal use of the electromagnet plate 32. After the electromagnet plate 32 is energized, the magnetism repels the magnet 31 at the lower end of the connecting rod 29. Therefore, in the working state, the electromagnet plate 32 is closed, and the tensioning spring 30 drives the connecting rod 29 to descend, prompting the piezoelectric ceramic ring 17 and the lifting and pressing plate 18 to press against the atomizing nucleus pore diaphragm 16 to maintain a pressed and fixed state. When the atomizing nucleus pore diaphragm 16 needs to be replaced, the electromagnet plate 32 is energized, and the magnet 31 moves upward under the action of the repulsive force, prompting the tensioning spring 30 to be compressed, driving the connecting rod 29 to rise, completing the separation of the piezoelectric ceramic ring 17 and the lifting and pressing plate 18 from the atomizing nucleus pore diaphragm 16, which is easy to operate and has a high degree of automation.

[0057] Operation process: Step S1, after a certain period of normal use, prepare to replace the atomizing nucleus pore membrane 16 according to the plan, and turn off the power;

[0058] Step S2, rotating the top cover 21, separating the top cover 21 and the atomizing conduit 22, emptying the residual liquid in the liquid storage cavity 13 and cleaning the liquid tank 11;

[0059] Step S3, the lifting and lowering plate 18 is caused to rise in the vertical direction by the displacement mechanism, specifically, the electromagnet plate 32 is energized, the magnet 31 moves upward under the action of the repulsive force, causing the tension spring 30 to be compressed, driving the connecting rod 29 to rise, and the lifting and lowering plate 18 moves upward, and the arc groove 20 on the lifting and lowering plate 18 is separated from the arc protrusion 19 on the atomization nucleation pore membrane 16;

[0060] Step S4, removing the old atomizing nucleus pore membrane 16 and installing a new atomizing nucleus pore membrane 16;

[0061] Step S5, the lifting and lowering plate 18 is caused to descend in the vertical direction through the displacement mechanism, specifically: the electromagnetic plate 32 is closed, the tensioning spring 30 drives the connecting rod 29 to descend, and the piezoelectric ceramic ring 17 and the lifting and lowering plate 18 are pressed against the atomizing nucleus pore diaphragm 16, and the pressed and fixed state is maintained. The lifting and lowering plate 18 descends and the arc groove 20 is engaged and fixed with the arc protrusion 19 on the atomizing nucleus pore diaphragm 16, and then the new solution is injected into the liquid storage chamber 13, and the top cover 21 is tightened to complete the replacement step, and the old atomizing nucleus pore diaphragm 16 is recycled and cleaned in batches.

[0062] The two displacement mechanisms disclosed in Examples 2 and 3 cause the lifting and pressing plate 18 to change its movement direction in the vertical direction. The entire process is simple to operate and has a high degree of automation. The replacement process saves time and effort, and the atomization core pore diaphragm 16 can be quickly replaced, thereby reducing the probability of blockage of the atomization core pore diaphragm 16, simplifying the cumbersome maintenance process of the existing atomizer, and improving the convenience of using the atomizer.

[0063] Example 3

[0064] In Example 3, the water-drawing mechanism includes a hose disposed in the atomizing tank 14 and the liquid storage chamber 13, and the hose is driven by a peristaltic pump, and the peristaltic pump drives the water-drawing pipe 23 to draw water, and the water intake amount and speed are controllable, so as to improve the accuracy and stability of the continuous operation of the device.

[0065] Implementation principle: The present invention discloses an atomizer with a replaceable nuclear pore diaphragm, which is convenient for clamping and fixing the atomizing nuclear pore diaphragm 16 by setting a clamping component, that is, the lifting and lowering plate 18 is driven by the displacement mechanism to complete the vertical movement, and when the lifting and lowering plate 18 descends, the arc-shaped groove 20 on the lifting and lowering plate 18 is embedded in the arc-shaped protrusion 19 on the atomizing nuclear pore diaphragm 16, so that the lifting and lowering plate 18 and the atomizing nuclear pore diaphragm 16 are clamped and fixed, and at the same time, the piezoelectric ceramic ring 17 is connected to the lifting and lowering plate 18, and then the piezoelectric ceramic ring 17 is caused to be in close contact with the atomizing nuclear pore diaphragm 16, which is convenient for subsequent excitation of the piezoelectric ceramic ring 17, so that the atomizing nuclear pore diaphragm 16 generates high-frequency vibration, and at this time, the liquid is adsorbed from the liquid storage cavity 13 to the atomizing groove 1 through the water-drawing mechanism. 4. The piezoelectric ceramic ring 17 cooperates with the atomizing core pore diaphragm 16 to generate high-frequency vibration, which prompts the microporous umbrella-shaped expansion side to repeatedly impact the liquid. The liquid passes through the umbrella-shaped expansion side and the flow rate is accelerated and sprayed out from the micropores to form atomization. After use, the displacement mechanism can be used to drive the lifting and pressing plate 18 to rise, and the piezoelectric ceramic ring 17 and the lifting and pressing plate 18 are separated from the atomizing core pore diaphragm 16. The atomizing core pore diaphragm 16 can be easily replaced, which is convenient for the maintenance of the atomizing core pore diaphragm 16. At the same time, it can also be replaced after the atomization of a specific liquid is used according to needs to avoid clogging of the atomizing core pore diaphragm 16 and maintain stable and efficient atomization output. At the same time, only the atomizing core pore diaphragm 16 is replaced, and its maintenance cost is low, which is convenient for daily batch use.

[0066] It should be noted that the component connection relationships not specifically mentioned in this application are assumed to adopt the existing technology. Since they do not involve the invention and are widely used in the existing technology, the structural connection relationships are not described in detail.
