201215417 六、發明說明： 【發明所屬之技術销域】 本發明關於—要被散佈的組成物諸如 佈於空氣的領域。 一香水組成物散 較精確地，本發明關於-種適於將—要被散佈之㈣ 物散佈於周圍空氣中的總成。此總成包含一用於容納一可 燃液體及要被散佈之μ物之混合物的巾部。其還包含— 用於蒸發可燃液體及要被散佈之組成物的區域’，、該 域適於通過該”被供應以該可缝體及料被散佈之纽

0277875公開的 專利申請案或專利中描述的催化燃燒器係特別已知的。 已發現此等燃燒器具有缺陷。 特別地，使用先前技藝中之此等燃燒器會遇到點火困 難。點火意味著藉由在此情況中為一火焰的一熱源開始催 化燃燒。 一方面，此等習知燃燒器需要一用於點火的大火焰， 3 201215417 這在使用者安全方面是不令人滿意的。這是因為依據裝有 燃料的燃燒器之飽和度，因此依據容納燃燒器且包含可燃 液體之容器的填充度，燃燒器點火所需火焰尺寸在10到 15 cm之間。 另一方面，已發現，依據容納燃燒器之容器之尺寸， 其可能充滿燃料，進而防礙下次點火，或至少使下次點火 困難。這是因為燃燒器在一時間t之飽和度取決於容器之形 式，這有時可造成燃燒器的重新點火故障。 另外，目前的燃燒器有一個缺點，它需要點火時間， 因此需要時間維持火焰在1到2分鐘之間，這對使用者而言 太長。 因此存在對一擺脫上述限制，且特別具有改進的，更 安全且更有效點火條件的燃燒器裝置的需求。 I：發明内容3 在此脈絡中，本發明之目的是提出一解決此需求之裝 置。 因此本發明之標的是一種適於將一要被散佈之組成物 散佈於空氣中的總成，該總成包含： -一用於容納一可燃液體及要被散佈之組成物之一混 合物的中部； -一用於蒸發該可燃液體及該要被散佈之組成物的區 域，該蒸發區適於通過該中部被供應以該可燃液體與該要 被散佈的組成物之一混合物，該蒸發區包含至少一與周圍 空氣接觸的外壁，此等外壁中至少一者形成一用於將該組 201215417 成物散佈於空氣中的區域，及 -一催化燃燒之燃燒器區，其包括一催化劑，且具有至 少一外壁與周圍空氣接觸，該蒸發意欲由該燃燒器區加 熱，及 -一内部分離元件，其傳導熱量，且不滲透任何液體， 該元件形成燃燒器區與蒸發區之間的一間隔，該蒸發區適 於在其外壁將可燃液體蒸汽釋放至周圍空氣中，且該燃燒 器區適於在其外壁容納此等蒸汽，且藉由催化燃燒將此等 蒸汽燃燒， 該總成之特徵在於，至少該中部與該蒸發區，及任選 地該燃燒器區由一具有一至少35%孔隙率的多孔材料製 成。 使用蒸汽之燃燒原理免除關於容器形式及體積的問 題，且因此免除總成之燃料輸出及供應問題。 這是因為，當先前技術之一燃燒器充滿燃料時，例如 因為其還未被使用一定量時間，所以其因被淹沒而不可以 再點火，且火焰溫度不足以將其乾燥，因此不足以開始催 化作用。在使用依據本發明使用蒸汽燃燒的該總成的情況 下，即使未使用達一定量時間，且不論此時間是多少，催 化或燃燒器區從不充滿可燃液體，這允許每次都能點火而 不停止激發催化作用。 另外，，由於催化作用開始發揮，依據本發明之總成 具有比先前技術之燃燒器需要火焰的時間較短的優勢。在 本發明中，該火焰必須達一5到20秒的時間段，然而在先前 201215417 技術中，該時間段在1到2分鐘之間。依據本發明之總成點 火的必要火焰尺寸與先前技術之裝置相比也被減小。火焰 在2到5cm之間。另外，其可能依據蒸發區高度而被預定。 至少依據本發明之該總成之中部及蒸發區必須是多孔 的。這是因為，爲了散佈香水，絕對需要總成（即中部及蒸 發區）之支座能夠允許液體香水通過，這必要地包括多孔支 座。 孔隙率必須必要地至少是35%，否則，就蒸汽燃燒而 言，會在蒸發區觀察到依據本發明之總成難以發揮作用。 特別地，已發現當蒸發之孔隙率低，特別地低於35%時， 蒸汽難以供應到燃燒器區，其後果如下： -不能開始或快速停止激發催化作用，因為來自可燃氣 體的蒸汽量不足， -蒸發區由於香水未充分蒸發且仍束缚在結構中而積 垢，及 -香水在蒸發區蒸發不足及嗅覺品質有限。 然而，中部及/或蒸發區之孔隙率必須維持在80%以 下。這是因為，如果孔隙率在80%以上，也會觀察到系統 故障，這可例如體現為可燃液體供應過多，因此液體消耗 過多。此後果是一高度蒸發，這導致一吸熱現象。液體本 身因其存在而冷卻蒸發區。蒸發區溫度太低，香水蒸發困 難。 分離元件之作用是雙重的： -首先，其有效傳導熱量， 201215417 _其-欠，其必須提供液體在蒸發區與燃燒器區之間的總 不 > 透丨生.燃燒器區不能與可燃液體接觸，否則將在由蒸 八啟動的催化區點火上有困難。這是因為，在供應過大時， 可燃液體充滿燃燒器區，且因此將其媳滅。 因此’其包含不滲透液體的材料，且較佳地一無孔材 料，即不滲透任一流體。 … …、孔材料可從玻璃、珠瑯或一金屬或塑膠材料中選擇。 例如，該内部分離元件由金屬，且較特定地由鋁（其在 -溫度2(TC具有ηπϋ的導熱率）製成。這是因為紐具 有充分傳導性且因此能夠加熱散佈區之優勢，這讓香水充 分蒸發，且防止積垢。然而，鋁也不是一過分導熱材料， 過分導熱材料會有將太多熱量傳導至散佈區的風險，且削 弱香水之散佈。此鋁分離元件可特定地具有一小於1毫米 厚度’較佳地在0.2到1毫米之fa1，且尤其較佳地等於〇 = 米。 、_笔 該分離元件可另外包含一部份孔材料，諸如存在於聚 矽氧中，其可滲透氣體但不滲透液體。 有利地’中部及蒸發區，且任選地燃燒器區由一具有 -35%到腦’或甚至在40%到7〇%，且較佳地在5〇%到6〇% 的孔隙率的多孔材料製成。 此多孔材料包含從高嶺土、堇音石爲χ, 里月石及一耐火化合物、 -致孔劑、-黏結劑及任選地-導熱率大於6〇瓦特每米克 耳文的導熱化合物之一混合物中選擇的材料之至少一者。 較佳地’使用一耐火化合物、一致孔才丨 双扎釗、—黏結劑及

此組成物具有易於掌控的性質及一品質，且因此能夠 被用於任一形式燃燒器。因此由此組成物製成的該等燃燒 器或該等燃燒器元件具有在它們整個體積上都均質的物 理、化學及機械特性，以及從一燃燒器，或燃燒器元件複 製至另一者的性質。 諸導熱化合物中至少一者例如是碳化石夕。 較佳地，每一耐火化合物的導熱率小於每一導熱化合 物之導熱率。每一耐火化合物可特別地從氧化鋁、氧化矽、 富銘紅柱石、氧化锆、堇青石、正長岩或其混合物之—者 中選擇。該耐火化合物較佳地是富鋁紅柱石。 有利地’每一黏結劑從任一能在一小於或等於1〇〇〇攝 氏度的溫度下被實施燒結的無機化合物中選擇。該黏結劑 例如是玻璃，較佳地是硼矽玻璃。 每一致孔劑有利地以粒度測定法從任一被掌控及控制 的成孔劑中選擇。該致孔劑例如是石墨。 依據本發明之一特定形態，該化合物按占其總重量的 一百分比計，包含1%到30%的至少一導熱化合物，30%到 201215417 70%的至少一耐火化合物，2%到30%的至少一黏結劑，及 5 %到40%的至少一致孔劑。 依據本發明之一較特定形態，該組成物按占其總重量 之一百分比計，包含5%到25%的至少一導熱化合物，40% 到65%的至少一耐火化合物，5%到25%的至少一黏結劑， 及8%到35%的至少一致孔劑。 該燃燒器區可由一上述多孔材料或一無孔材料製成。 此多孔或無孔材料必須導熱且例如是一陶竞或一金屬。 依據本發明，該總成可包含三可拆開工件，一包括蒸 發區及中部的第一工件、一包括燃燒器區的第二工件及一 包括内部分離元件的第三工件。 本發明之另一實施例由加入一單件的内部分離元件組 成，該單件包括蒸發區、中部及燃燒器區。該内部分離元 件可因此被置於此單件内，以形成蒸發區域燃燒器區之間 的間隔。 依據本發明之一形態，燃燒器區佔據依據本發明之總 成的一頂部周邊部分，且散佈區佔據總成之一頂部中心部 分，其藉由内部分離元件與燃燒器區隔開。換句話說，散 佈區被置於總成頂端且透過分離元件由燃燒器區圍繞並加 熱。 依據本發明之一較佳實施例，中部在總成之一底端包 含一實質上軸向的腔室，該腔室適於容納一芯且容納可燃 液體與組成物之混合物，該組成物將藉由接觸此浸泡在該 混合物中的芯被散佈。 201215417 該芯有利地由一多孔材料製成。然而，任何使中部能 夠藉由毛細作用而被供以液體燃料的材料可組成一可用於 本發明的芯。因此該芯是任一習知芯，例如棉芯。其可另 外是一由礦物原料製成的芯，例如由礦物纖維或陶瓷製成 的这。 依據本發明之該總成在其頂端可包含介於腔室頂部與 周圍空氣之間的一通道。此通道特別地允許蒸發區中未燃 燒氣體適當地放出，且因此使其積垢減少。 該腔室可具有一5到6mm，較佳地5.5mm的直徑，一距 蒸發區頂端高達2mm的距離。該通道可具有一 1.5到3mm， 較佳地2mm的直徑。 例如，第一工件形狀可以是圓柱形，在其中心一圓柱 腔室在第一工件之底端。此第一工件可包括一支撐裝置， 用於容納且支撐第二及第三工件。一支撐裝置可由在第一 工件周圍的一L型邊緣形成。第三工件可具有一適於圍繞著 第一工件置於其頂部的形狀。第二工件可具有適於圍繞著 第一工件置於其頂部的形狀，使得第三工件形成第一工件 與第二工件之間的内部分離元件。第二工件及第三工件例 如是具有至少一L型邊緣的環形形式。第三工件可具有一截 頭圓錐體形外部周邊，這促進容納在其外壁的蒸汽之催化 燃燒。 催化劑較佳地至少被沉積在燃燒器區的一外周部。因 此，例如，該催化劑沉積在第二工件之外側及周圍，在截 頭圓錐體形邊緣。該催化劑也可被沉積在燃燒器區之一頂 10 201215417 部’這使蒸發區能夠被更好地加熱，且因此限制未燃燒殘 餘物累積。 該催化劑較佳地是一金屬，且可特別地從鋁、鈀及铑 中選擇。較佳地使用鉑。 >儿積鉑之數量在〇.5mg到3mg足以保證依據本發明之 總成發揮作用。然而’一較大的量，有利地3〇rng到2〇〇mg， 且較佳地在5〇mg到160mg防止蒸發區積垢。 依據本發明，要被散佈於周圍空氣的組成物可特別地 是一香水組成物。其可另外是一驅蚊組成物，一抗蟎組成 物或一抗邊組成物。 依據本發明使用的可燃液體可以是一乙醇，例如異丙 醇，或任何其他符合目前規則的適當液體燃料。其蒸發及 催化燃燒必須不發出對香水不利的不良氣味。 例如，依據本發明之總成適於以—可燃液體及—要被 散佈之組成物之一混合物來發揮作用，該組成物包含異丙 醇、任選地丙酮、任選地水，及香水。較特定地，此一混 5物按貝量可包含70%到99%的異丙醇’ 〇%到丨8的丙酮， 〇%到10%的水，及高達2%的香水。百分比係關於混合物之 總質量來提供。 依據本發明之總成適於以通常用作一可燃液體的異丙 醇來發揮作用，也以-比異丙醇更易揮發的化合物來發揮 作用，例如丙酮。然而，因為該等燃燒器會被液體沒過， 所以目前習知的燃燒器不能使用此一可燃液體。這是因為 通常發生的催化反應會由於此可燃液體輸入過多而不能激 201215417 發。 丙酮在20°C的周圍溫度下的蒸汽張力（24.7 kPa)大於異 丙醇(4.4 kPa)的。因此丙酮比異丙醇蒸發得更快。丙酮蒸發 是吸熱的。其在燃燒器帶走熱量’這具有冷卻且促進停止 激發催化作用的效果。丙酮每小時的消耗（大於3〇g/h)比異 丙醇（大約20-25g/h)高很多。丙酮之黏度（在2〇°C是0.32 mPaS)低於異丙醇(在20°C是2.37 mPaS)。由於此等原因，一 丙酮基混合物不能用於習知燃燒器。依據本發明之總成藉 由解決可燃液體過大供應及可燃液體蒸發過多的問題而能 夠以此類型混合物來發揮作用。 依據一特定有利實施例，依據本發明之總成也包含一 第二催化劑，稱為一液體燃燒催化劑，其被置於處在藤發 區3的周圍及中間部分的一區域’且較精確地，在一所謂液 體燃燒區（在包含第二催化劑之區域的頂部）。 因此，在使用此一第二催化劑的情況下，依據本發明 之總成的燃燒由下者混合而成： -在燃燒器區的蒸汽燃燒區，及 -在蒸發區之散佈區的液體燃燒區。 δ玄液體燃燒催化劑較佳地是一金屬，且可特別地從 鉑、鈀及铑中選擇。 較佳地使用較佳地在30mg到200mg，更好地在50到 160mg的鉑，以限制甚至防止總成積垢。 圖式簡單說明 本發明之其他特徵及優勢將藉由指示方式而非限制方 12 201215417

水在蒸發後在此被散佈於周圍空氣中。 可燃液體蒸汽在一處於蒸發區3之周圍及底部或中部 的區17，即，在此等蒸汽被燃燒的燃燒器區5及其外壁6之 下被散發。 中部2包含一腔室9,其適於容納一芯（未示於圖中）。 總成1在一頂端包含在腔室9之一頂部與周圍空氣之間 的一通道10。 總成1可包含三可拆開工件，分別示於第2A圖、第2B 圖、第3圖及第4圖中。 一第一工件8包括蒸發區3及中部2。此第一工件8也包 括一筒11。筒11意欲容納並夾住該芯，且也意欲裝在一包 含可燃液體及香水組成物之混合物的容器上，芯浸泡於該 混合物中。較精確地，筒11可裝在例如燒瓶形式的一容器 的流出口。 在圖式中，筒11形成第一工件8之一整體部分。然而， 依據本發明，該筒可以是可從第一工件拆開的另一工件。 在此情況中，筒與第一工件之結合必須使可燃液體與香水 組成物之混合物能夠在此二工件之間循環。 在第2A圖及第2B圖中，第一工件8包含一 L型邊緣12用 於接受第四圖所示之一第三工件，第三工件包括内部分離 14 201215417 元件7。中部2及蒸發區3由一具有至少35%孔隙率的多孔 材料製成。 如第3圖所示，一第二工件包括燃燒器區5。 内部分離元件7是一L型環形式，用於首先被置於第一 工件8之L型邊緣12上，其次容納第二工件，如第1B圖所 示，第二工件的内周壁也具有一L型邊緣12。 例如，總成1之高度是16.5mm，包括筒11之高度，燃燒 器區5之高度是3到3.5mm，且可燃蒸汽散發區17之高度是 6到10mm。特別地，對於丙醇而言，區17之高度大約為 7mm，而對於異丙醇而言大約為9mm。 然而，此等高度可以是使依據本發明之裝置能夠發揮 作用的任何高度。一足以使催化作用發生並維持，且足以 使此區釋放的熱量被傳導至蒸發區那麼遠的燃燒器區高 度是必要的。此燃燒器區高度決定火焰之尺寸，其隨著燃 燒器區之高度而增加。另外，可燃蒸汽散發區17之高度必 須足以提供充分蒸發，且使催化部分能夠發揮作用。催化 之啟動可由總成之頂部及/或藉由燃燒器區下面的部分， 即區Π來實施。最好在燃燒器區下面之此部分實施，因為 其被供應更多燃料。 可以提供要依從的燃燒器與蒸發區之間的高度比例， 以正確點火且限制火焰高度。例如，針對使用丙酮作為燃 料，燃燒器區高度與蒸發區高度比大約為1:2 ;針對使用 異丙醇作為燃料，此比大約是1:3。 第5圖繪示一催化燃燒燒瓶13，其適於容納可燃液體與 15 201215417 要被散佈之組成物的一混合物14。此燒瓶13也適於在其頂 部容納依據本發明之一總成，該總成容納一浸泡在混合物 14中的芯15。 燒瓶13可以是任何能夠容納依據本發明之一具有一芯 的總成之形狀的任一容器，該芯被浸泡在容納在此容器中 的一混合物中。燒瓶13具有一流出口 16，總成1被固定在 此。 第6圖及第9圖繪示一被放置在處於蒸發區3之周圍及 中部的區17，且較精確地，在一所謂液體燃燒區18的第二 所謂液體燃燒催化劑存在的效果，液體燃燒區18處於區17 之頂部。為此，下列比較測試被實施： 1. 燃燒被實施，直到第1A圖所示依據本發明之總成完 全空，該總成僅在燃燒器區5包含一催化劑： -在此燃燒結束時，拍攝總成之一照片（第6圖），且 -在作用20分鐘後產生一紅外熱成像圖（第7圖）； 2. 燃燒也被實施，直到依據本發明之一總成之一第二 實施例清空，該總成包含與第6圖總成相同的可燃液體及 要被散佈之組成物的混合物，依據本發明之該總成的此第 二實施例也包含一第二所謂液體燃燒催化劑被置於區17 : -在此燃燒結束時，拍攝總成之一照片第8圖），且 -在作用20分鐘後產生一紅外熱成像圖（第9圖）； 在第7圖及第9圖之熱成像圖中，溫度被指示在±20°C。 「燃燒直到完全清空」在本發明之意義内意味著燃燒 被允許持續直到可燃液體及要被散佈之組成物的混合物 16 201215417 完全消失。 在完全燃燒後，如第8圖所示該混合燃燒的總成具有一 中心散佈區（4)，其從點火到燈空維持清潔。最高部分是具 有催化環(5)的蒸汽燃燒區（6)。就在蒸汽燃燒環(6)之下的 灰色區對應（液體）燃燒區（18)，且液體燃燒區（18)之下的區 對應蒸汽散發區（Π)。 第9圖繪示總成1在完全清空後，在中心散佈區（4)處及 蒸汽燃燒環(6)下面，比第8圖所示更髒。 在第8圖中，可看到液體燃燒區18在溫度412°C下，高 於第6圖中區18僅為150°C之溫度。另外，在蒸汽燃燒區6 溫度整體提升：這在第9圖中是537°C而在第7圖中僅為 489t。這意味著，第8圖總成之區17及18比第6圖總成的 更熱，在蒸發區有更大的熱散佈。另外，第8圖總成之區6 也比第6圖的更熱，藉由分離元件7有更好的熱傳導。 綜上所述，在區18存在液體催化致使燃燒器之映射的 分佈修改，且因此致使其沒有積垢。 C圖式簡單說明3 第1A圖繪示依據本發明之一總成之一第一實施例的透 視不意圖，

Description of the invention: [Technical sales field to which the invention pertains] The present invention relates to a composition to be dispersed, such as in the field of air. A perfume composition is more precise, and the present invention relates to an assembly suitable for distributing the (four) material to be dispersed in the surrounding air. The assembly comprises a towel portion for containing a mixture of a flammable liquid and an antigen to be dispensed. It further comprises - a region for evaporating the flammable liquid and the composition to be dispersed, the field being adapted to pass through the mixture of the "supplied body and the material to be dispersed", the evaporation region Including at least - an outer soil in contact with ambient air. At least one of the outer walls is formed - a region for dispersing the composition in the air. The assembly also includes a combustible combustion zone comprising a catalyst, and Having at least one outer wall in contact with ambient air, the evaporation zone being intended to be heated by the burner zone. I: Prior art j. Background of the invention is numbered WO 2008/023112, WO 2008/023113, ΕΡ 1491819, ΕΡ 1491818, WO 99/63267 and The catalytic burners described in the published patent application or patent are specifically known. These burners have been found to have drawbacks. In particular, the use of such burners in the prior art would encounter ignition difficulties. Catalytic combustion is initiated by a heat source that is a flame in this case. On the one hand, such conventional burners require a large flame for ignition, 3 201215417 which is in use The safety aspect is unsatisfactory because of the saturation of the burner with fuel, so the burner requires a flame size of 10 to 15 cm depending on the filling degree of the container containing the burner and containing the flammable liquid. On the other hand, it has been found that depending on the size of the container containing the burner, it may be full of fuel, thereby preventing the next ignition, or at least making the next ignition difficult. This is because the burner is saturated at a time t. The degree depends on the form of the container, which can sometimes cause a re-ignition failure of the burner. In addition, current burners have a disadvantage in that they require ignition time, so it takes time to maintain the flame between 1 and 2 minutes. It is too long. Therefore, there is a need for a burner device that overcomes the above limitations, and particularly has improved, safer and more efficient ignition conditions. I: SUMMARY OF THE INVENTION In this context, the object of the present invention is to propose A device for solving this need. Therefore, the present invention is directed to an assembly suitable for dispersing a composition to be dispersed in the air, the assembly package : a central portion for containing a mixture of a flammable liquid and a composition to be dispersed; - a region for evaporating the flammable liquid and the composition to be dispersed, the evaporation zone being adapted to pass through the central portion Supplying a mixture of the flammable liquid and one of the compositions to be dispersed, the evaporation zone comprising at least one outer wall in contact with ambient air, at least one of the outer walls forming a layer for spreading the 201215417 product into the air a region, and - a catalytic combustion burner zone, comprising a catalyst having at least one outer wall in contact with ambient air, the evaporation intended to be heated by the burner zone, and - an internal separation element that conducts heat, And without permeating any liquid, the element forms a space between the burner zone and the evaporation zone, the evaporation zone being adapted to release combustible liquid vapor to the surrounding air at its outer wall, and the burner zone is adapted to be received on its outer wall Such steam, and combusting the steam by catalytic combustion, the assembly being characterized by at least the central portion and the evaporation zone, and optionally the burner zone A porous material having a porosity of at least 35% percent. The use of steam combustion principles eliminates problems with the form and volume of the vessel and therefore eliminates fuel output and supply problems for the assembly. This is because when one of the prior art burners is full of fuel, for example because it has not been used for a certain amount of time, it cannot be re-ignited because it is submerged, and the flame temperature is not enough to dry it, so it is not enough to start. Catalysis. In the case of using the assembly using steam combustion according to the present invention, the catalytic or burner zone is never filled with flammable liquid, even if it is not used for a certain amount of time, regardless of the time, which allows ignition every time. The excitation is not stopped. In addition, the assembly according to the present invention has the advantage that the burner requires less time than the prior art because the catalytic action begins to play. In the present invention, the flame must be for a period of 5 to 20 seconds, whereas in the prior art 201215417 technique, the period was between 1 and 2 minutes. The necessary flame size of the assembly fire in accordance with the present invention is also reduced as compared to prior art devices. The flame is between 2 and 5 cm. In addition, it may be predetermined depending on the height of the evaporation zone. At least the middle portion of the assembly and the evaporation zone must be porous in accordance with the present invention. This is because, in order to distribute the perfume, it is absolutely necessary that the support of the assembly (i.e., the middle and the evaporation zone) can allow the liquid perfume to pass through, which necessarily includes a porous support. The porosity must necessarily be at least 35%. Otherwise, in the case of steam combustion, it will be observed in the evaporation zone that the assembly according to the invention is difficult to function. In particular, it has been found that when the porosity of evaporation is low, in particular below 35%, steam is difficult to supply to the burner zone, the consequences of which are as follows: - The catalytic action cannot be initiated or stopped quickly because the amount of steam from the combustible gas is insufficient - The evaporation zone is fouled due to insufficient evaporation of the perfume and still bound in the structure, and - the perfume is insufficiently evaporated in the evaporation zone and the olfactory quality is limited. However, the porosity of the central and/or evaporation zone must be maintained below 80%. This is because if the porosity is above 80%, a system failure can also be observed, which can be manifested, for example, by excessive supply of flammable liquid and therefore excessive liquid consumption. The consequence is a high degree of evaporation which leads to an endothermic phenomenon. The liquid itself cools the evaporation zone due to its presence. The evaporation zone temperature is too low and the perfume evaporation is difficult. The function of the separating element is twofold: - First, it effectively conducts heat, 201215417 _ its - owed, it must provide a total non-liquid between the evaporation zone and the burner zone. The burner zone cannot be flammable Liquid contact, otherwise it will be difficult to ignite in the catalytic zone initiated by steaming. This is because, when the supply is too large, the flammable liquid fills the burner zone and thus annihilates it. Thus, it contains a liquid impermeable material, and preferably a non-porous material, i.e., does not penetrate any fluid. ..., the hole material can be selected from glass, beads or a metal or plastic material. For example, the inner separating element is made of metal, and more specifically of aluminum (which has a thermal conductivity of ηπϋ at -2 (TC has ηπϋ). This is because the neon has sufficient conductivity and thus the advantage of being able to heat the spreading zone, which Allows the perfume to evaporate sufficiently and prevent fouling. However, aluminum is not an excessively conductive material, and excessively conductive materials have the risk of conducting too much heat to the distribution zone and weakening the dispersion of the perfume. This aluminum separation element may have a thickness of less than 1 mm 'preferably fa1 of 0.2 to 1 mm, and particularly preferably equal to 〇 = m. _ pen The separating element may additionally comprise a part of the pore material, such as in polyfluorene oxide, It is permeable to gases but impermeable to liquids. Advantageously 'the middle and evaporation zones, and optionally the burner zone from one to -35% to the brain' or even between 40% and 7%, and preferably at 5〇 Made of a porous material having a porosity of from 6% to 6% by weight. The porous material comprises kaolin, yinite, yttrium, a refractory compound, a porogen, a binder, and optionally a thermal conductivity. Heat conduction greater than 6 watts per megagram At least one of the materials selected from the mixture of one of the compositions. Preferably, 'using a refractory compound, a uniform pore, a double-strand, a binder, and 201215417, optionally a thermal conductivity greater than 60 watts per meter-gram a mixture of one of the thermally conductive compounds of the present invention. A composition for obtaining a porous material of a burner for producing a catalytic combustion or a catalytic combustion, comprising at least one refractory compound, at least one binder, At least a uniform pore agent and at least one thermally conductive compound having a thermal conductivity greater than 60 watts per meter-gram, the composition being described in the published International Patent Application No. WO 2008/023111. An easy-to-control nature and a quality, and thus can be used in any form of burner. Thus the burners or burner elements made from the composition have physical, chemical properties that are homogeneous throughout their volume. And mechanical properties, as well as the nature of replication from one burner, or burner element to the other. At least one of the thermally conductive compounds is, for example, a carbon carbide day. The thermal conductivity of each refractory compound is less than the thermal conductivity of each thermally conductive compound. Each refractory compound may be specifically derived from alumina, yttria, mullite, zirconia, cordierite, syenite or mixtures thereof. The refractory compound is preferably mullite. Advantageously, each binder is selected from any inorganic compound that can be sintered at a temperature of less than or equal to 1 deg C. The bond. The agent is, for example, glass, preferably borosilicate glass. Each uniform pore agent is advantageously selected by particle size measurement from any of the controlled and controlled pore formers. The porogen is, for example, graphite. In a specific form, the compound comprises from 1% to 30% of at least one thermally conductive compound, from 30% to 201215417 70% of at least one refractory compound, and from 2% to 30% of at least one binder, based on a percentage of its total weight. And 5% to 40% of at least uniform pores. According to a more specific aspect of the invention, the composition comprises from 5% to 25% of at least one thermally conductive compound, from 40% to 65% of at least one refractory compound, from 5% to 25% by weight of the total weight. At least one binder, and at least 8% to 35% of the uniform pores. The burner zone can be made of a porous material as described above or a non-porous material. This porous or non-porous material must be thermally conductive and, for example, a pottery or a metal. In accordance with the present invention, the assembly can include three detachable workpieces, a first workpiece including an evaporation zone and a middle portion, a second workpiece including a burner zone, and a third workpiece including internal separation elements. Another embodiment of the invention consists of the addition of a single piece of internal separation element comprising an evaporation zone, a middle zone and a burner zone. The internal separation element can thus be placed within this single piece to form an interval between the burner zones of the evaporation zone. In accordance with one aspect of the invention, the burner zone occupies a top peripheral portion of the assembly in accordance with the present invention, and the scatter zone occupies one of the top center portions of the assembly, which is separated from the burner zone by internal separation elements. In other words, the distribution zone is placed at the top of the assembly and surrounded by the burner zone and heated by the separation element. In accordance with a preferred embodiment of the present invention, the central portion includes a substantially axial chamber at one of the bottom ends of the assembly, the chamber being adapted to receive a core and containing a mixture of flammable liquid and composition, the composition The core soaked in the mixture is dispersed by contact. 201215417 The core is advantageously made of a porous material. However, any material which enables the middle portion to be supplied with liquid fuel by capillary action can constitute a core which can be used in the present invention. Thus the core is any conventional core, such as a cotton core. It may alternatively be a core made of mineral material, such as mineral or ceramic. The assembly according to the invention may include a passage between the top of the chamber and the surrounding air at its top end. This passage specifically allows the unburned gas in the evaporation zone to be properly discharged, and thus its fouling is reduced. The chamber may have a diameter of 5 to 6 mm, preferably 5.5 mm, a distance of up to 2 mm from the top of the evaporation zone. The passage may have a diameter of 1.5 to 3 mm, preferably 2 mm. For example, the first workpiece shape may be cylindrical with a cylindrical chamber at the bottom end of the first workpiece at its center. The first workpiece can include a support device for receiving and supporting the second and third workpieces. A support means may be formed by an L-shaped edge around the first workpiece. The third workpiece may have a shape adapted to be placed around the top of the first workpiece. The second workpiece may have a shape adapted to be placed on top of the first workpiece about the first workpiece such that the third workpiece forms an internal separation element between the first workpiece and the second workpiece. The second workpiece and the third workpiece are, for example, annular forms having at least one L-shaped edge. The third workpiece may have a frustoconical outer periphery which promotes catalytic combustion of the vapor contained in its outer wall. Preferably, the catalyst is deposited at least on an outer peripheral portion of the burner zone. Thus, for example, the catalyst is deposited on the outside and around the second workpiece at the frustoconical edge. The catalyst can also be deposited on top of one of the burner zones 10 201215417' which allows the evaporation zone to be better heated and thus limits the accumulation of unburned residues. The catalyst is preferably a metal and may be selected in particular from aluminum, palladium and rhodium. Platinum is preferably used. > The amount of galvanic platinum in the range of 5.5 mg to 3 mg is sufficient to ensure that the assembly according to the present invention functions. However, 'a larger amount, advantageously 3 〇 rng to 2 〇〇 mg, and preferably 5 〇 mg to 160 mg to prevent fouling in the evaporation zone. According to the invention, the composition to be dispersed in the surrounding air may in particular be a perfume composition. It may additionally be a mosquito repellent composition, an anti-caries composition or an anti-edge composition. The flammable liquid used in accordance with the present invention may be monoethanol, such as isopropanol, or any other suitable liquid fuel that meets current regulations. Its evaporation and catalytic combustion must not give off an unpleasant odor to the perfume. For example, the assembly according to the invention is suitable for functioning as a mixture of a flammable liquid and a composition to be dispersed, the composition comprising isopropanol, optionally acetone, optionally water, and perfume. More specifically, the blend may comprise from 70% to 99% isopropyl alcohol 〇% to 丨8 acetone, 〇% to 10% water, and up to 2% perfume. The percentage is provided for the total mass of the mixture. The assembly according to the invention is suitable for functioning as isopropanol which is normally used as a flammable liquid, and also as a compound which is more volatile than isopropanol, such as acetone. However, currently known burners cannot use this flammable liquid because the burners are not emptied by the liquid. This is because the usual catalytic reaction will not be able to excite 201215417 due to the excessive input of this flammable liquid. The vapor tension (24.7 kPa) of acetone at ambient temperature of 20 ° C is greater than that of isopropanol (4.4 kPa). Thus acetone evaporates faster than isopropanol. Evaporation of acetone is endothermic. It carries away heat in the burner' which has the effect of cooling and promoting the cessation of the catalytic action. The consumption per hour of acetone (greater than 3 〇g/h) is much higher than that of isopropyl alcohol (about 20-25 g/h). The viscosity of acetone (0.32 mPaS at 2 °C) is lower than isopropanol (2.37 mPaS at 20 °C). For these reasons, an acetone-based mixture cannot be used in conventional burners. The assembly according to the present invention can function as a mixture of this type by solving the problem of excessive supply of flammable liquid and excessive evaporation of flammable liquid. According to a particularly advantageous embodiment, the assembly according to the invention also comprises a second catalyst, referred to as a liquid combustion catalyst, which is placed in a region around the vine-producing zone 3 and in the middle portion' and more precisely In a so-called liquid combustion zone (on top of the zone containing the second catalyst). Therefore, in the case of using this second catalyst, the combustion according to the assembly of the present invention is mixed by: - a steam combustion zone in the burner zone, and - a liquid combustion zone in the dispersion zone of the evaporation zone . The δ 玄 liquid combustion catalyst is preferably a metal and may be selected in particular from platinum, palladium and rhodium. Preferably, from 30 mg to 200 mg, more preferably from 50 to 160 mg, of platinum is used to limit or even prevent buildup fouling.

The same elements shown in Figures 1 through 5 are denoted by the same reference numerals. [F-package method] The assembly 1 according to the present invention shown in Figs. 1A and 1B includes a middle portion 2, a region 3 for evaporating a flammable liquid and a composition to be dispersed, and a burner for catalytic combustion. Zone 5 and an interior 13 201215417 Separation element 7. The burner section 5 occupies a top peripheral portion of the assembly 1 and has at least one outer wall 6 in contact with ambient air. The evaporation zone 3 comprises a distribution zone 4 in which the composition to be dispersed, for example fragrant water, is dispersed in the surrounding air after evaporation. The flammable liquid vapor is liberated in a zone 17 which is around and in the bottom or middle of the evaporation zone 3, i.e., under the burner zone 5 where the steam is burned and its outer wall 6. The middle portion 2 includes a chamber 9 adapted to receive a core (not shown). The assembly 1 contains a passage 10 between the top of one of the chambers 9 and the surrounding air at a top end. Assembly 1 can include three detachable workpieces, which are shown in Figures 2A, 2B, 3, and 4, respectively. A first workpiece 8 includes an evaporation zone 3 and a middle section 2. This first workpiece 8 also includes a barrel 11. The cartridge 11 is intended to contain and clamp the core and is also intended to be contained in a container containing a mixture of a flammable liquid and a perfume composition, the core being immersed in the mixture. More precisely, the cartridge 11 can be mounted, for example, at the outlet of a container in the form of a flask. In the drawings, the barrel 11 forms an integral part of the first workpiece 8. However, in accordance with the present invention, the cartridge can be another workpiece that can be detached from the first workpiece. In this case, the combination of the barrel and the first workpiece must allow a mixture of flammable liquid and perfume composition to circulate between the two workpieces. In Figs. 2A and 2B, the first workpiece 8 includes an L-shaped edge 12 for receiving a third workpiece shown in the fourth figure, and the third workpiece includes an internal separation 14 201215417 element 7. The middle portion 2 and the evaporation portion 3 are made of a porous material having a porosity of at least 35%. As shown in FIG. 3, a second workpiece includes a burner zone 5. The inner separating element 7 is in the form of an L-ring for first being placed on the L-shaped edge 12 of the first workpiece 8, and secondly accommodating the second workpiece, as shown in Fig. 1B, the inner peripheral wall of the second workpiece also has a L-shaped edge 12. For example, the height of the assembly 1 is 16.5 mm, including the height of the drum 11, the height of the burner zone 5 is 3 to 3.5 mm, and the height of the combustible vapor emission zone 17 is 6 to 10 mm. In particular, for propanol, the height of zone 17 is about 7 mm, and for isopropanol it is about 9 mm. However, such heights may be any height that enables the device in accordance with the present invention to function. A burner zone high enough to allow the catalysis to occur and maintain and which is sufficient to release the heat released to this zone to the evaporation zone is necessary. The height of this burner zone determines the size of the flame, which increases with the height of the burner zone. In addition, the height of the combustible vapor emission zone 17 must be sufficient to provide sufficient evaporation and to enable the catalytic portion to function. The initiation of catalysis can be carried out by the top of the assembly and/or by the portion below the burner zone, i.e., the zone. It is best to implement this part of the burner area because it is supplied with more fuel. A ratio of the height between the burner and the evaporation zone to be compliant can be provided to properly ignite and limit the flame height. For example, for the use of acetone as the fuel, the ratio of the height of the burner zone to the height of the evaporation zone is approximately 1:2; for the use of isopropanol as fuel, the ratio is approximately 1:3. Figure 5 illustrates a catalytic combustion flask 13 adapted to contain a mixture 14 of flammable liquid and a composition to be dispersed 15 201215417. This flask 13 is also adapted to receive at its top a assembly according to the invention which accommodates a core 15 soaked in the mixture 14. The flask 13 may be any container capable of accommodating the shape of an assembly having a core according to one of the present invention, the core being immersed in a mixture contained in the container. The flask 13 has a first-class outlet 16, and the assembly 1 is fixed thereto. Figures 6 and 9 illustrate the effect of a second so-called liquid combustion catalyst placed in the zone 17 in the middle and the middle of the evaporation zone 3, and more precisely in a so-called liquid combustion zone 18, liquid combustion Zone 18 is at the top of zone 17. To this end, the following comparative tests were carried out: 1. Combustion was carried out until the assembly according to the invention shown in Figure 1A was completely empty, the assembly containing only one catalyst in the burner zone 5: - at the end of this combustion, Photographing one of the assemblies (Fig. 6), and - generating an infrared thermographic image after 20 minutes of action (Fig. 7); 2. Combustion is also performed until one of the assemblies according to one of the inventions is second The embodiment is emptied, the assembly comprising the same flammable liquid as the assembly of Figure 6 and a mixture of the composition to be dispersed, the second embodiment of the assembly according to the invention also comprising a second so-called liquid combustion catalyst Placed in zone 17: - at the end of this burn, photograph of one of the photographs of the assembly, Fig. 8), and - after 20 minutes of action, an infrared thermography image is produced (Fig. 9); in Fig. 7 and Fig. 9 In the thermographic image of the figure, the temperature is indicated at ±20 °C. "Combustion until completely empty" means within the meaning of the invention that combustion is allowed to continue until the mixture of flammable liquid and the composition to be dispersed 16 201215417 completely disappears. After complete combustion, the mixed combustion assembly as shown in Fig. 8 has a central dispersion zone (4) that maintains clean from ignition to light. The highest part is the steam combustion zone (6) with the catalytic ring (5). The gray zone just below the steam combustion ring (6) corresponds to the (liquid) combustion zone (18), and the zone below the liquid combustion zone (18) corresponds to the vapor emission zone (Π). Fig. 9 shows that the assembly 1 is completely dirty after being completely emptied, at the center dispersion area (4) and under the steam combustion ring (6), as shown in Fig. 8. In Fig. 8, it can be seen that the liquid combustion zone 18 is at a temperature of 412 ° C, which is higher than the temperature of zone 18 in Fig. 6 of only 150 ° C. In addition, the temperature in the steam combustion zone 6 is increased overall: this is 537 ° C in Figure 9 and only 489 t in Figure 7. This means that zones 17 and 18 of the assembly of Figure 8 are hotter than the assembly of Figure 6, with greater heat dissipation in the evaporation zone. In addition, the zone 6 of the assembly of Fig. 8 is also hotter than that of Fig. 6, with better heat transfer by the separating element 7. In summary, the presence of liquid catalysis in zone 18 causes a modification in the distribution of the map of the burner and thus causes it to be free of fouling.
