'About - Kind [Prior Art] When the inkjet head Pnnthead on the inkjet printer Unk je "rinter" is contaminated or contaminated with residual ink, it is often an abnormality in inkjet performance. - Generally speaking, In order to maintain the normality of the inkjet (four), the traditional method is mostly to scrape off the pollutants on the dragon, or to use the cleaning liquid (6) to call the rtlon) to flush the ride on the nozzle. The limited effect 'especially the way to use the knife may even cause the spray to do this. How to provide a garment and method that can effectively clean the inkjet head has become an important issue. SUMMARY OF THE INVENTION An embodiment of the present invention provides an ink jet head cleaning apparatus including a gas generating element. The aforementioned ultrasonic element is disposed in the tubular structure and is capable of emitting ultrasonic waves to clean the aforementioned hole, wherein at least a gas flow path is formed between the ultrasonic element and the tubular structure. The money element is connected to the front I (four) channel, thereby forming a negative in the tubular structure and thereby sucking the ink in the ink nozzle from the orifice. The present invention further provides an ink jet head cleaning method. The package 201102276 includes a supply-tubular structure and an ultrasonic component, wherein the ultrasonic component is disposed in the tubular structure, and at least the ultrasonic component is formed between the ultrasonic component and the tubular structure. - an air flow passage; the ultrasonic component facing the at least one orifice of the inkjet head; providing a gas element for connecting the airflow passage, and omitting the airflow passage to extract air in the tubular structure, thereby causing a negative in the tubular structure The ink in the inkjet head overflows from the orifice and fills: between the ultrasonic component and the orifice; and, the ultrasonic component is activated to clear the obstruction or contaminant of your orifice. In order to make the above-described features of the present invention more comprehensible, the following detailed description of the preferred embodiments and the accompanying drawings. [Embodiment] The ink jet head cleaning apparatus of the present invention-an embodiment is used for cleaning an ink jet head 1 on an ink jet apparatus, which mainly includes an ultrasonic wave removing member 7. It should be specially noted that the upper and lower ends of the camp-like structure 6 have openings, wherein the tubular structure: the surface 3 of the head 1 is separated by a gap, and the ultrasonic element 7 is the inside of the official structure 6, and Inkjet head! At least the upper nozzle hole 5 is cleaned, wherein the air flow passages S1, S2 are formed between the ultrasonic wave element 7 and the tubular structure 6, respectively. And can be connected to a getter element through the suction hole = both sides of the ultrasonic component 7 and the exit hole 8 (not shown, the 102102276 suction gas can be a vacuum pump or a pumping pump. It can be seen that the aforementioned air flow passage 8 and the S2 acoustic wave element 7 and the tubular structure 6 are formed in the super air flow passage sm...a, wherein S2 can be independent or partially connected, and the foregoing The gas flow m, S2 can also be consolidated and forced; this flow channel, and jade π ^ 1U connected to form a single gas display). U-ultrasonic component 7 is solid (as shown in Figure 7B), when using the suction=f2 diagram, in the cleaning operation, firstly, only 7L of cattle are taken out of the first 9 holes of the tubular structure 6 (such as the brother 2 The arrow is not 9), at this time, the hollow structure in the tubular structure 6 can be wrinkled ~ a heart into a negative pressure, so that the outside of the field gift ~ the front H) direction into the tubular structure 6 in the head 1 ink 2 will be filled between the ultrasonic element pupils 5 via the 啧 5 5 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , Then, the supersonic 2 can be used as the conductive material, so that the contaminants in the vicinity of the nozzle hole 5 can be deactivated by the ink 4, so that the nozzle can be blocked and the inkjet effect can be avoided. The middle 4 is more likely to be sucked along the air flow path 8 S2 along with the ink 2. = It is understood that the 'cleansing shirt of the present invention can also (four) the ink jet head 1, the position of the knife cloth and correspondingly change the design or increase its size '= Γ cleaning a plurality of nozzle holes, the gas 4 S2 can be symmetric Or asymmetrically placed in the periphery of the ultrasonic wave. In addition, 201102276 or more than two air flow passages may be formed around the ultrasonic element 7 to facilitate the suction of the ink 2. Referring to Fig. 3 again, when the nozzle hole 5 is severely blocked, the tubular structure and the structure 6 can be abutted on the surface 3 of the ink jet head 1, so that the tubular 'degree of vacuum> can be increased to effectively Ink 2 in the inkjet head 1

As shown in Fig. 5, when the inkjet head 1 is not used, the aforementioned tubular structure can be used as The sealing cover is used to prevent the ink 2 from passing through the spray. It should be understood that the ultrasonic element 7 in the present embodiment has a kneading surface 71 (as shown in Fig. 5), and the 苴 can be - plane Face to the ink head 1. However, the aforementioned end faces 71 are also, 铋-, and hopper 9 M 疋 concave surfaces (as shown in Fig. 0A: not V or a shaped lens structure (as shown in Fig. 6B) to enhance the focusing and cleaning ability of the ultrasonic waves.
如第从，所示，通常一個噴墨頭以所需要 清潔的噴孔5僅有其中幾個，故可藉由凊潔部分噴孔5 以避免墨水的浪費；舉例而言’當僅需要清潔喷墨頭i 上之少部分噴孔5時’可設計喷墨頭清潔震置的尺寸小 到僅涵ϋ喷孔5(如第8A圖中的範圏α所示），然 而”若為了提高^頭丨的清·度，亦可設計喷墨頭清 潔裝置的尺寸並使其大到完全涵蓋噴墨顯1上的所有 喷孔：>(如第8Α圖中的範圍C2所示）。 j上所述，本發明提供一種噴墨頭清洗裝置及方 法，前述喷墨頭清洗裝置主要包括-管狀結構、一超音 波疋件以及-吸氣元件，其中透過在超音波元件旁形成 至少-氣流通道’並透過吸氣元件在管狀結構内產生適 當之負壓，可穩定地將噴墨頭内之墨水吸出，同時能使 墨水充填於超音波元件和喷孔之間。如此一來，超音波 =件便可湘墨水作為傳導介質，並透過超音波來有效 /月除喷孔上之阻塞物或污染物，接著污染物更可隨著墨 水流動而沿氣流通道一併被吸出，故不僅能大幅提升清 洗效率，同時更可避免噴孔在清洗過程中損壞。 雖然本發明以前述之較佳實施例揭露如上，然其並 非用以限定本發明。本發明所屬技術領域中具有通常知 識者，在不脫離本發明之精神和範圍内，當可做些許之 更動與潤飾。因此本發明之保護範圍當視後附之申請專 201102276 利範圍所界定者為準。 201102276 【圖式簡單說明】 第1圖表示本發明〜實施例之噴墨頭清洗裝置示 意圖； 第2圖表示本發明〜實施例之吸氣元件吸出管狀 結構内氣體之示意圖； 第3圖表示本發明〜實施例之管狀結構抵接喷墨 頭表面之示意圖；As shown in the above, usually only one of the nozzles 5 for cleaning the ink jet head is required, so that the waste of the ink can be avoided by cleaning the partial nozzle hole 5; for example, when only cleaning is required When a small number of nozzle holes 5 are formed on the ink jet head i, the size of the ink jet head cleaning device can be designed to be as small as the nozzle hole 5 (as shown in Fig. 8A), however, The clarity of the head lice can also be designed to size the inkjet head cleaning device to a size that fully covers all of the orifices on the inkjet display: > (as indicated by the range C2 in Figure 8). As described above, the present invention provides an ink jet head cleaning apparatus and method, the ink jet head cleaning apparatus mainly comprising a tubular structure, an ultrasonic wave element, and a getter element, wherein the transmission is formed at least beside the ultrasonic element. The air flow passage ' generates a suitable negative pressure in the tubular structure through the suction member, and the ink in the inkjet head can be stably sucked out, and at the same time, the ink can be filled between the ultrasonic component and the injection hole. Thus, the super Sound wave = piece of ink can be used as a conductive medium, and it is transmitted through ultrasonic waves. In addition to obstructions or contaminants on the orifice, the contaminants can be sucked out along the airflow path as the ink flows, so that not only can the cleaning efficiency be greatly improved, but also the nozzle can be prevented from being damaged during the cleaning process.
