DETAILED DESCRIPTION

[0030] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments in conjunction with the accompanying drawings:

[0031] refer to Figure 1-3 , a microporous atomizing sheet, comprising:

[0032] A microporous atomizing sheet body 11 is provided with a plurality of atomizing holes 12, a connecting ring plate 13 is provided at the bottom end of the microporous atomizing sheet body 11, a liquid storage portion is formed on the microporous atomizing sheet body 11 and between the plurality of atomizing holes 12, an upper touch and lower immersion block 14 is movably provided in the connecting ring plate 13 and below between the plurality of atomizing holes 12, and a driving member is provided between the upper touch and lower immersion block 14 and the connecting ring plate 13.

[0033] The microporous atomizing sheet body 11 is used to generate high-frequency vibration after being energized to break up the liquid into mist, and the plurality of atomizing holes 12 are used to facilitate the mist to be sprayed out of the microporous atomizing sheet body 11 after the microporous atomizing sheet body 11 breaks up the liquid into mist.

[0034] The connecting ring plate 13 is used to cooperate with the housing of the atomizing device so that the microporous atomizing sheet body 11 is located at the top of the housing of the atomizing device, and there is liquid in the housing of the atomizing device.

[0035] The upper contact and lower immersion block 14 has the function of absorbing and storing water, and the driving member is used to drive the upper contact and lower immersion block 14 to move; the upper contact and lower immersion block 14 is used to immerse in the liquid in the shell of the atomization device when the microporous atomization sheet body 11 is not powered on and is powered on for a predetermined time, so as to absorb and store the liquid in the shell of the atomization device, and wait for the high-frequency vibration of the microporous atomization sheet body 11 to remove the impurities attached to the atomization hole 12; the upper contact and lower immersion block 14 is used to be driven to continuously move up and down after the microporous atomization sheet body 11 is powered on for a predetermined time, and each time it moves up and down, it first rises to contact and squeeze the liquid storage part of the microporous atomization sheet body 11 and then moves down The upper contact and lower immersion block 14 is used to make the liquid in the shell of the atomization device adhere to the liquid storage part of the microporous atomization sheet body 11 when it rises to contact and squeeze the liquid storage part of the microporous atomization sheet body 11, so that the microporous atomization sheet body 11 can break up the liquid attached to the liquid storage part into mist. Since the impurities in the atomization hole 12 are removed, the mist can be sprayed out to the outside of the microporous atomization sheet body 11 smoothly and quickly, thereby preventing the mist sprayed out of the microporous atomization sheet body 11 from falling back to the atomization hole 12, causing the efficiency and quality of the mist sprayed out of the microporous atomization sheet body 11 to decrease. The situation is prevented, thereby preventing the mist sprayed to the outside of the microporous atomizing sheet body 11 from falling back to the atomizing hole 12 and causing the mist to be intermittent when being sprayed to the outside of the microporous atomizing sheet body 11, thereby preventing the mist sprayed to the outside of the microporous atomizing sheet body 11 from falling back to the top surface of the microporous atomizing sheet body 11 and causing the top surface of the microporous atomizing sheet body 11 to accumulate liquid; the upper contact and lower immersion block 14 is used to absorb and store the liquid in the shell of the atomizing device when it descends and immerses in the liquid in the shell of the atomizing device, thereby providing liquid for the liquid storage part of the microporous atomizing sheet body 11 during each up and down movement, thereby avoiding intermittent atomization; The upper contact and lower immersion block 14 is used to only contact and squeeze the liquid storage part of the microporous atomization sheet body 11 during each up and down movement and then no longer contact the liquid storage part of the microporous atomization sheet body 11, so that the microporous atomization sheet body 11 can not only break up the liquid attached to the liquid storage part into mist but also greatly reduce the contact time with the upper contact and lower immersion block 14, thereby preventing bubbles from being generated in the liquid storage part of the microporous atomization sheet body 11 due to long-term contact with the upper contact and lower immersion block 14, thereby avoiding intermittent liquid atomization by the microporous atomization sheet body 11 and preventing the mist from being unable to quickly pass through the atomization hole 12 and spray out to the outside of the microporous atomization sheet body 11.

[0036] The connection ring plate 13 and the shell of the atomizing device can be connected by snapping, fastener connection, glue bonding, etc. The shell of the atomizing device is a water tank in an air humidifier, the shell of the atomizing device is an essential oil pot in an aromatherapy machine, and the shell of the atomizing device can also be other structures; when the shell of the atomizing device is a water tank in an air humidifier, the liquid in the water tank in the air humidifier is pure water; when the shell of the atomizing device is an essential oil pot in an aromatherapy machine, the liquid in the essential oil pot in the aromatherapy machine is aromatherapy essential oil.

[0037] The shape of the liquid storage part is an upward convex shape, so as to adapt to the top of the upper touch and lower soaking block 14 when the upper touch and lower soaking block 14 contacts and squeezes the liquid storage part of the microporous atomizing sheet body 11, thereby increasing the amount of liquid attached when the upper touch and lower soaking block 14 contacts and squeezes the liquid storage part of the microporous atomizing sheet body 11, thereby preventing the liquid from being completely atomized before the upper touch and lower soaking block 14 contacts and squeezes the liquid storage part of the microporous atomizing sheet body 11 next time, resulting in intermittent atomization. When the mist is sprayed to the outside of the microporous atomizing sheet body 11 through a plurality of atomizing holes 12, it is prevented that the adjacent mists are mixed with each other, causing the mist to be unable to quickly move away from the microporous atomizing sheet body 11 or even fall back onto the atomizing holes 12 and / or the microporous atomizing sheet body 11.

[0038] The bottom end surface of the microporous atomizing sheet body 11 and the outside of the liquid storage part are provided with a liquid-receiving anti-falling ring plate 15 having a predetermined elastic coefficient. The liquid-receiving anti-falling ring plate 15 is used to elastically deform when the upper touch-down soaking block 14 rises and is pressed against the top of the upper touch-down soaking block 14, so as to avoid the upper touch-down soaking block 14 so that the top of the upper touch-down soaking block 14 is adapted to the liquid storage part of the microporous atomizing sheet body 11, so that the liquid in the shell of the atomizing device is attached to the liquid storage part of the microporous atomizing sheet body 11; the liquid-receiving anti-falling ring plate 15 is used to restore its original shape when the upper touch-down soaking block 14 descends and is not pressed against by the upper touch-down soaking block 14. The liquid attached to the liquid storage part of the microporous atomization sheet body 11 is supported, and due to the inherent tension of the liquid surface, when the microporous atomization sheet body 11 atomizes the liquid, the liquid-receiving and anti-falling ring plate 15 can prevent the liquid attached to the liquid storage part of the microporous atomization sheet body 11 from escaping from the liquid storage part of the microporous atomization sheet body 11, thereby preventing the situation in which no liquid is atomized before the upper and lower immersion block 14 contacts and squeezes the liquid storage part of the microporous atomization sheet body 11 next time, resulting in intermittent atomization.

[0039] The driving member includes two connecting boxes 16, which are respectively arranged on the top of both sides of the inner wall of the connecting ring plate 13, two rotating stepping motors 17, the rotating stepping motor 17 is arranged in the connecting box 16, the rotating end of the rotating stepping motor 17 passes through the connecting box 16, two limiting plates 18 are arranged on the rotating end of the rotating stepping motor 17, and two driving wires 19, one end of the driving wire 19 is arranged on the upper contact and lower immersion block 14 and the other end is arranged on the rotating end of the rotating stepping motor 17, and the other end of the driving wire 19 is located between the two limiting plates 18.

[0040] An anti-damage and reduction member is provided between the two driving wires 19 and the upper touch and lower soaking block 14. The anti-damage and reduction member is used to prevent the upper touch and lower soaking block 14 from being pulled by the two driving wires 19 when the two driving wires 19 drive the upper touch and lower soaking block 14 to move up and down, thereby extending the service life of the upper touch and lower soaking block 14; the anti-damage and reduction member is used to reduce the liquid absorbed and stored by the upper touch and lower soaking block 14 from escaping from the upper touch and lower soaking block 14 when the two driving wires 19 drive the upper touch and lower soaking block 14 to rise.

[0041] The upper touch and lower dip block 14 is a spherical upper touch and lower dip block, and the anti-damage and reduction component includes an anti-damage and reduction cover 20, which is arranged between the two driving lines 19 and located outside the spherical upper touch and lower dip block. The top end of the spherical upper touch and lower dip block and the bottom end of the spherical upper touch and lower dip block both pass through the anti-damage and reduction cover 20, and the volume passed through by the top end of the spherical upper touch and lower dip block is greater than the volume passed through by the bottom end of the spherical upper touch and lower dip block.

[0042] The inner wall of the anti-damage and anti-fall cover 20 is provided with a plurality of limit-lifting, stabilizing and anti-swaying blocks 21. The plurality of limit-lifting, stabilizing and anti-swaying blocks 21 are used to limit the spherical upper touch and lower dip block in the anti-damage and anti-fall cover 20, so as to prevent the spherical upper touch and lower dip block from moving in the anti-damage and anti-fall cover 20 when the two driving wires 19 drive the upper touch and lower dip block 14 to move up and down, thereby improving the stability of the spherical upper touch and lower dip block when contacting and squeezing the liquid storage part of the microporous atomizing sheet body 11 and reducing the shaking degree of the two driving wires 19.

[0043] An extension column 22 is provided at the bottom end of the upper touch and lower soaking block 14. The extension column 22 has a water absorption and storage function, and is used to reduce the descending distance of the upper touch and lower soaking block 14 when the upper touch and lower soaking block 14 descends and store the liquid in the housing of the atomizing device in the upper touch and lower soaking block 14, thereby reducing the time for each up and down movement of the upper touch and lower soaking block 14, thereby shortening the time for providing liquid to the liquid storage part of the microporous atomizing sheet body 11, and avoiding intermittent atomization.

[0044] The spherical upper touch and lower dip block and the extension column 22 can be made of sound-absorbing sponge or polyurethane water-absorbing sponge or other materials.

[0045] The microporous atomizing sheet body 11 includes a connecting shell 23, a substrate 24 is arranged in the connecting shell 23, an annular vibration sheet 25 is arranged between the substrate 24 and the connecting shell 23, a plurality of the atomizing holes 12 are arranged on the substrate 24 and located in the annular vibration sheet 25, the annular vibration sheet 25 is located on the top surface of the substrate 24, and the liquid storage part is formed on the substrate 24 and located between the plurality of the atomizing holes 12. The substrate 24 is made of a conductive material, such as a metal material, and the annular vibration sheet 25 is a piezoelectric ceramic sheet.
