Background

Electrohydrodynamic atomization of fluids is becoming increasingly important in the field of coating processes. An apparatus for applying a care product, such as a sunscreen, to the body of a person using electrohydrodynamic atomization is known, for example, from PCT/EP 2018/060117.

Many atomizer nozzles have been shown to be disadvantageous when electrohydrodynamic atomization is applied. Furthermore, problems often arise in the necessary cleaning of the system, since in the case of the high voltages required for electrohydrodynamic atomization, it is not straightforward to simply clean with water.

Disclosure of Invention

The object of the invention is therefore to improve the function of electrohydrodynamic atomizers, in particular to simplify cleaning.

This object is achieved by the subject matter of the invention according to claim 1. Advantageous refinements and advantageous embodiments are specified in the dependent claims.

The invention relates to an atomizer nozzle system, in particular for an electrohydrodynamic atomizer, wherein a plurality of nozzles are included in a nozzle hood (nozzle cap) and, in order to form the nozzles (nozzle), at least one nozzle opening (nozzle opening), at least one nozzle channel (nozzle channel) and at least one nozzle sleeve (nozzle socket), wherein the nozzle hood is arranged on at least one carrier body (carrier), wherein the carrier body comprises a nozzle connection (nozzle-connector) for each nozzle sleeve. The invention is characterized in that the nozzle hood is arranged releasably and fixedly on the carrier body.

By releasably fixing the nozzle hood to the carrier body, the nozzle hood can be removed and removed from the apparatus unit of the electrohydrodynamic atomizer and cleaned, for example, with water or another solvent. This also allows for easy replacement by the user himself after wear has occurred. In addition, alternative nozzle caps may also be used, the geometry and other characteristics of which are adapted to other fluids to be atomized.

A preferred embodiment provides that the nozzle hood is made at least in regions of a flexible material, in particular of a flexible electrical insulator, preferably silicone.

The use of a flexible material, such as silicone, allows dried fluid residues to be removed by simple deformation of the surface, for example by scraping the surface with a finger, since the hardened residues are broken by the deformation and can thus be removed.

Furthermore, the use of insulators has surprisingly been shown to facilitate electrohydrodynamic atomization. The atomization effect produced by the liquid, which is subjected to a high voltage, is improved by the guidance in the electrically insulated nozzle channel, which leads to a higher process reliability in electrohydrodynamic atomizer applications, for example, when applying care products such as sun protection creams.

Another preferred embodiment provides that the carrier body is made of a rigid material, preferably a plastic, such as PC, ABS, PE, PET or PP.

The rigid carrier body allows a flexible nozzle hood to be fixed precisely and reliably, for example by means of rigid parts for alignment and fixing.

Such rigid elements can be formed by projections or structures such as flanges or mushroom heads, but also by grooves or tongue elements into which corresponding mating structures of the nozzle cap then engage, in particular snap-fit, in particular elastically.

An advantageous development of the embodiment provides that the nozzle hood is held on the carrier body, preferably in a form-fitting manner, by elastic clamping of the latching elements or clamping of the flexible material.

The use of a flexible, rubber-like nozzle cap, preferably made of silicone (Silikon), allows the nozzle cap to be clamped elastically to the carrier body and thus released without tools. In the case of inflexible or partially flexible nozzle covers, it is also possible to achieve a releasable connection, for example by means of a latching element, simply without tools.

A further preferred embodiment provides that the nozzle cover comprises a base structure (base-structure), in particular a base plate (base-plate) or a base frame (base-frame), on which a nozzle structure for forming the atomizer nozzle is arranged, wherein the base structure is made of a comparatively more rigid material, in particular PC, ABS, PE, PET or PP, etc., compared to the nozzle structure, which is preferably made of silicone, and preferably comprises at least one connecting part, in particular a latching part, for forming a preferably releasable connection with the carrier.

The flexible, bendable layer of the nozzle molding, which is formed on the rigid base structure, allows the provision of a nozzle molding, for example of silicone, without having to dispense with mechanical latching elements for releasable connection to the carrier body. In addition, the tactile sensation during the removal and installation of the nozzle hood is improved in this way, since a certain dimensional stability is achieved. The base structure can be designed as a plate with recesses for the nozzle nipple and/or nozzle sleeve or as a frame structure which is supported and stabilized only at the necessary points.

In a preferred development, the nozzle hood comprises at least three nozzle openings each with an associated nozzle channel and an associated nozzle sleeve, wherein the nozzle openings in the nozzle region are maximally spaced apart from one another, in particular arranged one after the other along a zigzag line.

It has been shown that the provision of at least three nozzle openings results in process-reliable atomisation characteristics. More nozzle openings are also conceivable, wherein the number of nozzle openings preferably varies within the single digit range.

However, it is important that the nozzle openings in the area of the nozzle hood available for arrangement are spaced apart to the greatest possible extent, i.e. a spacing which is as great as possible is maintained. Here, a zigzag arrangement in one plane is desired, since this arrangement maximizes the spacing between the nozzle openings. In determining the spacing of the nozzle openings, care must also be taken with regard to the nozzle geometry itself, since the openings are never located directly at the edge of the area, but are usually surrounded by a nozzle body which accommodates the nozzle channel.

In addition, an advantageous development is characterized in that the nozzle opening of the nozzle projects out of the plane of the nozzle cover, wherein the rim of the projecting nozzle is preferably designed as a continuously curved line, in particular the nozzle rim is asymmetrical on the rim side relative to the opposite rim side of the nozzle, in particular has a curvature which is at least 1.5 times greater.

In order to define the nozzle shape, in particular to accommodate the nozzle channel inside the nozzle body, the nozzle body is provided with a nozzle opening which projects out of the plane of the nozzle cover. The plane of the nozzle hood is here a substantially flat base on which the nozzle molding is arranged. The edge regions of the projections described in the following exemplary embodiments remain on the outside.

The rim or the side wall of the nozzle body extends here as a continuously curved line. Due to the arrangement at the largest possible distance, a smaller installation space is provided on the rim side of the nozzle body close to the edge of the nozzle hood compared to the opposite side. The curvature on the side remote from the edge can thus be more even, as will be explained in the following embodiments. A more flexible transition is thereby achieved which facilitates cleaning.

In a further advantageous embodiment, the nozzle hood and/or the base plate and/or the carrier plate are formed in one piece, preferably by an injection molding process.

The corresponding production allows one or more components to be produced cost-effectively and efficiently.

In addition, a further advantageous embodiment provides that the nozzle hood and the base plate and/or the carrier plate are constructed in one piece, preferably produced using a multicomponent injection molding process, or are connected to one another in another way, for example by means of an adhesive or vulcanization process.

The corresponding production allows one or more components to be produced cost-effectively and efficiently. In addition, by the two manufacturing methods just mentioned, inadvertent separation of these components of the nozzle cap is avoided, which provides a higher reliability against mistakes for the user.

Furthermore, it is provided that, in one embodiment, the nozzle cap encloses the connecting flange with an elastic section at the nozzle connection and forms a seal on this connecting flange by elastic deformation.

The nozzle cap, because of its releasability, must form a sealed joint on the nozzle joint of the carrier. This is preferably achieved as follows: the elastic section, for example made of silicone, sealingly embraces the connecting flange of the nozzle nipple, wherein the clamping force of the elastic section must be able to withstand the delivery pressure of the fluid to be atomized during operation of the electrohydrodynamic atomizer.

A preferred embodiment provides that the nozzle fitting has a cylindrical connecting flange, in particular with a circumferential sealing ring, and that the nozzle sleeve forms a corresponding cylindrical receptacle in order to provide a form-fit of the mutually engaging seals.

The sealing ring can also be formed as a projection directly formed on the connecting flange, in particular as a projection formed directly during injection molding, in order to avoid additional components or steps.

The corresponding cylindrical connecting flange can be produced in a simple and reliable manner by this production method and provides the user with a simple connection of the fluid system with a reliable sealing effect when mounting and dismounting the releasably connected nozzle cover.

By means of the shaped sealing bead, which is fixedly connected to the connecting flange, it is possible to achieve that the flexible, soft material, in particular silicone, of the nozzle cap forms a sufficient clamping force with the sealing bead on the connecting flange together with the seal, so that the nozzle cap is held on the carrier body by the clamping on the sealing bead.

An alternative preferred embodiment provides that the nozzle nipple has a conical connecting flange and the nozzle sleeve forms a corresponding conical receptacle in order to provide a form fit of the mutually engaging seals.

Furthermore, the conical connection flange allows a preferred centering effect during assembly, wherein the mutually abutting conical edges of the connection flange and the nozzle sleeve form a sealing contact.

A further preferred embodiment provides that the nozzle channel is designed in the form of a cone section or a cone cap, in particular as an end channel leading to the nozzle opening, wherein the end channel is preferably designed as a cylindrical or conical tube section.

This configuration of the nozzle channel is the subject of DE 102018133406.0, the disclosure of which is incorporated herein by reference. The corresponding design of the nozzle channel provides an advantageous form of a free jet of the fluid to be atomized before the effect of electrohydrodynamic atomization is active on the basis of the applied high voltage.

It is particularly preferably provided here that the nozzle opening of the atomizer nozzle is between 0.1mm and 0.3mm, preferably 0.2mm, and the length of the nozzle channel is between 4mm and 6mm, preferably 5.5 mm.

An advantageous embodiment of the atomizer nozzle system provides that an electrical contact element, in particular a high-voltage contact, is formed in the nozzle connection, wherein the contact projects into a fluid channel, which is preferably guided through the contact, in particular the distance between the electrical contact element and the nozzle opening is between 5mm and 20mm, preferably between 11mm and 15mm, in particular 14 mm.

For electrohydrodynamic atomization, a high voltage needs to be applied to the fluid to be atomized. The high voltage is particularly advantageously applied in the region of the carrier body, since otherwise contact points would also be provided in the nozzle hood.

The contact for high voltages is particularly advantageously designed as an electrical contact element, which projects into the fluid channel. The fluid passage here comprises a passage through the nozzle sleeve. In particular, the electrical contact element is preferably designed such that it is arranged in the flow direction of the fluid, in particular is flowed through by the fluid via an opening in the electrical contact element. In this way, the best effect of the high voltage is ensured, which in turn ensures that the fluid is subsequently energized (autofluding), which results in a process-reliable spraying process.

Electrohydrodynamic atomization is based on the instability of an energizable fluid, particularly a fluid that is sufficiently conductive at high voltages, in a strong inhomogeneous electric field. Where a high voltage is applied to the fluid. The fluid is deformed in this case into a cone, from whose tip a fine jet, the so-called jet, is emitted, which then immediately breaks down into a spray consisting of finely divided droplets. Under certain conditions, in the taylor cone mode, the droplets have a narrow size distribution.

The atomisation effect may also be improved by co-acting with a forced hydraulic supply of fluid flow, e.g. a pump.

Detailed Description

In particular, fig. 1 shows an electrohydrodynamic atomizer 1 comprising an atomizer portion 2 and a fluid tank 3.

On the atomizer part 2, in the upper front region, a nozzle system 4 is arranged. The nozzle system here comprises a first nozzle 10, a second nozzle 11 and a third nozzle 12.

The nozzles 10, 11, 12 are currently designed as nozzle bodies 14, 15, 16 which project from a plane 13 of the nozzle system 4, wherein the nozzle bodies are asymmetrically deformed with curved sides in their transverse direction 17 for extending the nozzle system 4.

Each nozzle 10, 11, 12 is provided with a nozzle opening 21, 22, 23 at its tip. These nozzle openings 21 and 22 are distanced from each other by as large a distance 24 as possible. The nozzles 22 and 23 are distanced from each other by a distance 25 as large as possible. The nozzles 21, 22, 23 are arranged in a zigzag pattern spaced apart so as to be sufficiently spaced apart in the plane 13 of the nozzle system 4.

The atomizer part 2 has a receptacle 30 around the nozzle system 4 for a cover (not shown) which covers and protects the nozzle system 4 in the transport state.

In addition, the atomizer portion 2 comprises at least one operating button 31 which can be used for activating the electrohydrodynamic atomizer 1 and for contacting a user in order to provide the necessary current during atomization. Further contacts, in particular operating buttons, are preferably provided, which are not shown at present, since they are arranged on the rear side, so that the electrohydrodynamic atomizer 1 can be operated without problems with both the left and the right hand.

Furthermore, an electrically conductive, preferably metallic or metallized, circumferential contact region, in the present case a contact ring 32, is provided on the atomizer part 2 in the region between the atomizer part 2 and the fluid reservoir 3 in order to be operable by the user as a contact for supplying the necessary current during atomization. Other arrangements on the device are also conceivable, provided that they achieve good and process-reliable contact.

Fig. 2 is a schematic cross-sectional view of a first embodiment of an atomizer nozzle system with a nozzle cap and carrier and a partial view of a variant of a nozzle joint.

The nozzle cap 40 is now shown removed from the carrier 41. Here, the nozzle cover 40 comprises a nozzle structure 42, which is currently made of silicone. The nozzle structure 42 forms nozzle bodies 43 which project from a plane 44 of the nozzle cover.

Below the nozzle structure 42, the nozzle hood 40 currently comprises a base plate 45 which is made of a more rigid material, in particular a more rigid plastic, than the silicone of the nozzle structure 42. In this way, the nozzle cap 40 is provided as a rigid component group which can be fixed well to the carrier 41 and can be released again.

In order to releasably fix the nozzle cover 40 to the carrier body 41, latching elements 50 are formed, which clampingly fix the nozzle cover 40 placed on the carrier body 41.

The atomizer nozzle 60 of the nozzle cover 40 comprises a nozzle opening 61 and a nozzle channel 62 which opens into a nozzle sleeve 63. The mating piece of the nozzle sleeve 63 is formed by a nozzle connection 64 on the carrier body 41. In the embodiment shown in the present case, the nozzle nipple 64 and the nozzle sleeve 63 are conically shaped, so that when the nozzle cap 40 is placed on the carrier body 41, the two conical edges abut against one another and form a seal.

A fluid channel 65 is provided in the nozzle connection 64, at the lower end of which an electrical contact 66 is arranged for introducing a high voltage into the fluid. This electrical contact is currently provided with an aperture in the region of the fluid channel 65, so that the fluid flows through the electrical contact 66 during its transport towards the nozzle opening 61.

In the partial view I, an alternative variant of a nozzle connection is shown, which, instead of a conical shape, has a cylindrical shape with a sealing element provided. This variation will be described in more detail below in fig. 3B, but may be applied at the marked locations of carrier 41, as described below.

Fig. 3a is a schematic perspective view of a second embodiment of an atomizer nozzle system with a nozzle hood 100 and a carrier 101.

Three atomizer nozzles 102, 103, 104 are provided on the nozzle cover 100. These atomizer nozzles have a curved edge on their nozzle body. See nozzle 103 for exemplary reference. The edge 105 shown on the front side has a continuously curved profile, with a significantly greater curvature being produced than the edge 106 shown on the rear side. The ramp-like structure of the rim of the nozzle body 110, 111, 112a allows for providing an easy-to-clean surface with a bulged nozzle body on which the spaced nozzles 102, 103, 104 have as large a distance as possible.

The carrier body 101, which is arranged below the nozzle hood 100, comprises a connecting flange 112b, 113, 114 for each atomizer nozzle 102, 103, 104. The connecting flange is currently of cylindrical design and comprises a sealing ring at its upper edge, which is currently designed as a directly formed sealing bead.

Fig. 3b shows a correspondingly enlarged view of the nozzle cover 200 placed onto the carrier 201.

Here, the nozzle cap 200 also comprises a silicone nozzle structure 202, which is arranged on a base structure 203 made of a more rigid plastic.

The connecting flange 204 of the carrier body 201 is of cylindrical design in the present case. A fluid channel 205 extends centrally in the connecting flange 204. At the lower end of the fluid channel 205, an electrical contact element 206 is provided, which has a central aperture 207 through which the fluid to be energized for electrohydrodynamic atomization flows, wherein the fluid is energized by means of an applied high voltage.

A sealing ring 210 is provided at the upper end of the connecting flange 204. The nozzle body 211 is currently equipped with a cylindrical nozzle sleeve 212, into which the connecting flange 204 projects, and forms a seal with its sealing ring 210 against the flexible silicone material of the nozzle body 211. Above the connecting flange 204, a nozzle channel 213 is located in the nozzle body 211, which opens at its upper end into an end channel 214. The nozzle opening 215 is in turn formed by the upper end of the end channel 214. The nozzle channel 213 is currently designed in the form of a conical, in particular conical cap section.

In this case, a preferred dimensioning of an embodiment provides that the diameter 220 of the nozzle opening 215 is 0.2 mm. The preferred design length 221 of the nozzle channel 213 is about 5.5 mm. The entire length 222 of the fluid channel 205 together with the nozzle channel 213 inside the nozzle is preferably up to approximately 14mm, wherein a free jet with a free jet length of 10mm to 15mm is thereby produced in front of the nozzle opening during atomization of the fluid (not shown) before the atomization effect is produced.
