Description

Improved spray device

An improved spray device, and more particularly to a spray device utilizing a liquid wicking plate having a through hole design.

Conventional ink cartridges or spray devices are commonly used to fill the foamed structure into the shaped outer casing and store the liquid in a sponge structure. However, it cannot accurately control the appearance and size of the micropores, and it needs to be mechanically (or manual) accurately assembled to complete the package.

In addition, during the use of the spray device, additional pressure is applied to the sponge structure to maintain the normal operation of the piezoelectric sheet during spraying, so that the micro-atomized droplets are smoothly sprayed.

In view of the above problems, the present invention provides an improved spray device which utilizes a liquid absorbing sheet having a plurality of microstructured through-hole designs to adsorb liquid into the microstructured through-holes of the liquid absorbing sheet by capillary action. It can replace the sponge structure used in the spray chamber of a commercially available spray device. In addition, the liquid absorbing sheet is made of a polymer material and is designed corresponding to the outer shell, so that the nozzle can smoothly spray the micro atomized droplets without pressurization. No leakage of liquid, and the use of polymer materials can precisely control the appearance and size of micropores.

This creation is an improved spray device comprising: a liquid holding case for The liquid accommodating sheet is disposed in the accommodating case and includes a plurality of through holes.

The detailed description of the present invention and the technical description are further described in the following examples, but it should be understood that these examples are for illustrative purposes only and are not to be construed as limiting.

Please refer to FIG. 1 to FIG. 2 . FIG. 1 is a cross-sectional view of the improved spray device of the present invention, and FIG. 2 is a perspective view of the three-dimensional structure of the liquid suction reservoir of the present invention. The present invention provides an improved spray device comprising: a liquid accommodating case 10 for accommodating a liquid 20 having an injection hole 13 disposed at the top of the spray device for injecting a liquid 20 and a perforation 14 It is disposed at the center of the liquid absorbing sheet 11 for guiding the injected liquid 20 into the liquid absorbing sheet 11, and a piezoelectric sheet spraying group 17 is located below the liquid accommodating box 10, which can accommodate the liquid 20 in the liquid accommodating box 10. Spray the spray outward.

The liquid absorbing sheet 11 is disposed in the accommodating case 10. The liquid absorbing sheet 11 includes a plurality of micro-structured through holes 12 for absorbing the ink by capillary action, so that no pressure is required The nozzle is smoothly sprayed with micro-atomized droplets.

Next, please refer to FIG. 3a to FIG. 3d and FIG. 4, FIG. 3a to FIG. 3d are perspective views of the liquid absorbing sheet of the present invention, and FIG. 4 is a cross-sectional view of the liquid absorbing sheet of the present invention. The shape of the through hole 12 of the liquid absorbing sheet may be a honeycomb shape 121, a square 122, a rectangle 123 or a circle 124. However, the embodiment is not limited thereto, and the shape of the through hole 12 may be any geometric shape.

In addition, as shown in FIG. 3b to FIG. 3c and FIG. 4, if the through hole 12 is a square 122 or a rectangle 123, it has a width W1 of 0.2 mm to 5 mm. In addition, as shown in FIG. 3d, if the through hole 12 is a circle In the shape 124, it has a diameter of 0.2 mm to 5 mm.

Further, the liquid absorbing sheet 11 may have a thickness H of 0.5 mm to 1 mm.

The material of the liquid absorbing sheet 11 is a polymer material. Due to the design of the polymer material, the cleaning can be more convenient and the nozzle can be smoothly sprayed with the micro atomized droplets without pressure.

Please refer to FIG. 1 and FIG. 5. FIG. 5 is a perspective view of the liquid storage sheets of the present invention stacked on each other. Wherein the liquid accommodating case 10 further comprises a plurality of liquid absorbing sheets stacked in the liquid accommodating case 10, and the plurality of liquid absorbing sheets 11 are stacked and stacked with each other to form a porous micro-flow path, in addition to being In addition to the irregular shape of the traditional sponge, the basic function of adsorbing and storing sufficient liquid can be achieved and the spray device can smoothly generate micro-atomized droplets.

Furthermore, referring to FIG. 1, the liquid storage box 10 further includes a liquid storage space 15 under the liquid absorbing sheet 11 for storing the liquid 20 dropped from the liquid absorbing sheet 11, so that more than the liquid will be It does not leak to the piezoelectric sheet spray group 17, forming a liquid buildup and excessive spraying.

However, the above is only the preferred embodiment of the present invention. When it is not possible to limit the scope of the creation of the creation, that is, the simple equivalent changes and modifications made by the applicant in accordance with the scope of the patent application and the content of the creation description are all It is still covered by this creation patent.
