New description: [New technical field] This creation is about an unpowered exhaust device, especially an unpowered exhaust device using the venturi principle (V e n t u r i). [Prior Art] As shown in the Republic of China, the new patent (Announcement No.: 1 7 5 1 8 0), please read the first picture, which is a perspective view of the prior art, and the second picture is a side view. The technical unpowered roof ventilator comprises a ventilating casing 105, a foreign body damper 123, and a low pressure generating pipe 107, which is known for its operation due to the low pressure generating pipe 10 7 pipe length only Extend into the vertical vent position of the ventilation cover 1 0 5 inside. If the external flowing gas contains rainwater or other foreign matter, it will easily pass through the foreign body damper 1 2 3 through the low pressure generating tube. When the 1 0 7 guide is introduced into the ventilating cover 1 〇 5, the rainwater or other foreign matter is brought into the ventilated casing 10.5 inner 1/3 vertical nozzle position, and then dropped into the interior of the building. Due to the poor design of the prior art and the lack of it, it has been plagued and plagued by the industry and consumers for a long time. Therefore, whether it can provide an unpowered row that enhances the use of the product and enhances the use value of the product. The gas installation does have its necessity, and this is also the motivation for creating inventions for this case. 5 M312641 [New content] The present invention discloses an unpowered exhaust device, a casing is a chamber having three vent holes therein; a τ-shaped outer portion is disposed in the chamber of the venting cover; a tube is formed, the opening is one of a small tubular shape and is disposed in a lateral portion of the T-shaped outer tube; by the above group, the airflow enters the T-shaped outer tube through the low-pressure tube to form a low-pressure region, attracting a T-shaped shape The gas at the bottom and the gas is exhausted from the outlet of the T-shaped outer tube. [Embodiment] Please refer to the third figure of this creation for the perspective view and the fourth view for the side view. As shown in the fourth figure, the original unpowered arrangement includes at least one ventilation cover 2 0 5 and two foreign bodies. The barrier 208, a low pressure generating tube 201, and a T-shaped outer tube 204 are formed. The ventilating cover 205 is provided with a three venting chamber, and the outer side of the air inlet and the exhaust vent of the two sides of the venting can be separately connected with a foreign body damper 2 0 8 and the third end of the venting hole is connected. a vent, wherein the opening of the venting opening of the venting cover 205 is small, and the opening of the venting opening is large; a low pressure generating tube 20 1 opening is one of a large tubular shape and is disposed within the venting cover 2 0 5 The outer tube of the T-shaped outer tube is covered by the T-shaped outer tube XX4, and the venting tube at the front edge of the T-shaped outer tube is formed in the tube. The external port of the resistor is set to be part of the system and the 2 04 system is set to 6 M312641.
年月日修正補充 計為擴管斜面之結構，可利於將導入至低壓生成管 2 0 1内之雨水或異物經由該斜面結構而加以排放， 且在其擴管處設有環狀規則性排列之氣孔2 0 6以增 加氣流排放之表面積，以利於氣流流經外部的通氣 口；此外，該低壓生成管201在T形外管 204之内 部則另設計為橫向延伸之加長設計’猎以防止導入 之氣流内所含之雨水或異物在通風殼罩2 0 5内停留 而掉落於外部的通氣口 。至於該通風殼罩2 0 5之前 後兩側管口端所設之異物攔阻器 2 0 8，係藉以確實 達成將空氣中大型異物隔絕於通風殼罩2 0 5之外為 目的，以避免大型異物之進入通風殼罩 205，因此 該異物攔阻器2 0 8係組合於通風殼罩2 0 5之外部。 請參閱第五圖所示，係為本創作無動力式排氣 裝置作動圖。其作動過程係利用自然界大氣流動 時，其中一部份氣流經由通風殼罩2 0 5之進氣端進 入低壓生成管 2 0 1，再流經通過 T形外管 2 0 4，經 由通風殼罩205之出氣端離開無動力式排氣裝置。 當氣流經過低壓生成管2 0 1到T形外管2 0 4時會產 生一低壓，此低壓會吸引在T形外管2 04下方之氣 流（由通氣殼罩 2 0 5 之第三端氣孔連接外部的通氣 口），使得氣流經由 T形外管 2 0 4排出於通風殼罩 2 0 5之排氣口。 7 M312641 請參閱第六圖所示，此時若通過T形外管 204 之氣流含有雨水或其它異物時，該雨水或異物將沿 著該加長設計的低壓生成管2 0 1，而導引至Τ形外 管2 0 4前端所形成擴管之斜面處滑落並排出通風殼 罩2 0 5外部，以避免在氣流導入的過程中掉落至外 部的通氣口 ，進而確保外部的通氣口的潔淨。另外 氣流在經由低壓生成管 2 0 1 進入而流經 Τ形外管 2 〇 4内部時，則將產生一橫向對流之低壓區，利用 氣體高壓往低壓移動之自然現象而將外部的通氣 口的氣流經由通風殼罩2 0 5垂直管導入，進而隨前 述橫向氣流排放。 綜上所述，本創作完全將習知技術之既有缺失 摒除，因此確具功效增進並提昇該項產品使用價 值，又申請前未曾公開及使用，亦非其所屬技術領 域中具有通常知識者依申請前之先前技術顯能輕 易完成，實符合新型專利要件，敬請 貴局賜准專 用權益。 8The year-and-month correction supplement is calculated as a structure for expanding the inclined slope, which can facilitate the discharge of rainwater or foreign matter introduced into the low-pressure generating pipe 201 into the inclined structure, and has an annular regular arrangement at the expansion pipe. The air hole 206 is configured to increase the surface area of the airflow to facilitate the flow of air through the external vent; in addition, the low pressure generating tube 201 is internally designed to extend laterally to the length of the T-shaped outer tube 204 to prevent The rainwater or foreign matter contained in the introduced airflow stays in the ventilating cover 205 and falls to the external vent. As for the foreign object damper 2 0 8 provided at the end of the ventilating cover before and after the ventilating cover, it is intended to prevent large foreign objects in the air from being isolated from the venting cover 20 5 to avoid large foreign objects. It enters the venting cover 205, so the foreign object damper 2 0 8 is combined outside the venting cover 205. Please refer to the fifth figure for the creation of a non-powered exhaust unit. When the actuation process utilizes the natural atmosphere flow, a part of the airflow enters the low pressure generation pipe 20 through the intake end of the ventilation casing 20 5, and then flows through the T-shaped outer pipe 2 0 4 through the ventilation cover. The outlet end of 205 leaves the unpowered exhaust. When the airflow passes through the low pressure generating tube 2 0 1 to the T-shaped outer tube 2 0 4, a low pressure is generated, which attracts the air flow under the T-shaped outer tube 604 (the third end vent of the venting cover 205) The external vent is connected to the exhaust port of the venting cover 205 through the T-shaped outer tube 204. 7 M312641 Please refer to the sixth figure. If the airflow passing through the T-shaped outer tube 204 contains rainwater or other foreign matter, the rainwater or foreign matter will be guided along the extended design low-pressure generating tube 210. The slanted surface of the expanded tube formed by the front end of the Τ-shaped outer tube 205 is slid down and discharged from the outside of the ventilating cover to avoid falling into the external vent during the introduction of the airflow, thereby ensuring the cleanliness of the external vent . In addition, when the airflow enters through the low pressure generating pipe 201 and flows through the inside of the dome-shaped outer pipe 2 〇4, a lateral convection low pressure zone is generated, and the external vent is used by the natural phenomenon that the gas high pressure moves to the low pressure. The air flow is introduced through a venting housing 205 vertical tube, which in turn is discharged with the aforementioned lateral air flow. In summary, this creation completely eliminates the existing defects of the prior art, so it has the effect of enhancing and enhancing the use value of the product, and has not been disclosed and used before the application, nor is it a common knowledge in the technical field. It is easy to complete according to the previous technical abilities that were applied before the application, and it is in line with the new patent requirements. Please ask for special rights. 8
