In addition, the antenna body 20 has a first opening 201 and a second opening 202 at the two ends of the hollow body 200, and the first opening 201 is connected to the detecting body 10. Preferably, the antenna body 20 is horn-shaped to have a better radiation field type for measurement by transmitting and receiving signals.
再者，該薄膜片30結合在該天線本體20上，並遮蓋該天線本體20的第二開口202。較佳地，該薄膜片具有複數孔隙，實際實施時，該薄膜片可由不織布、玻璃纖維或具有細緻孔洞之布料等所構成。 Furthermore, the film sheet 30 is bonded to the antenna body 20 and covers the second opening 202 of the antenna body 20.

In the present embodiment, the radar wave level gauge 1 is used in conjunction with a working gas 2, which is mainly used to generate a gas flow, so the type of gas used is not limited, but in practice, the work is performed. Gas 2 does not react with the measurement or measurement environment.
如圖4所示，本發明之雷達波物位計1使用時，該工作氣體2係通過該輸氣通道11並流經該中空腔體200，接著通過該天線透鏡40，並從該些輸氣孔洞41處流出。最後，該工作氣體2會流向該薄膜片30，並帶動該薄膜片30而使其產生變形。更具體而言，該薄膜片30受該工作氣體2的作用而產生膨脹或收縮變 形，藉此而令附著在該薄膜片30上(外側面)的粉塵3掉落，藉此達到清潔該薄膜片30的功能。 As shown in FIG. 4, when the radar wave level gauge 1 of the present invention is used, the working gas 2 passes through the gas passage 11 and flows through the hollow cavity 200, then passes through the antenna lens 40, and from the The vent hole 41 flows out. Finally, the working gas 2 will flow to the film sheet 30 and drive the film sheet 30 to deform it. More specifically, the film sheet 30 is expanded or contracted by the action of the working gas 2 In this manner, the dust 3 adhering to the outer side surface of the film sheet 30 is dropped, whereby the function of cleaning the film sheet 30 is achieved.

In this embodiment, the radar wave level gauge 1 further includes a sliding ball 50; preferably, the sliding ball 50 is a sphere formed by a low dielectric material. Moreover, the sliding ball 50 is disposed on an inner side surface of the film sheet 30 and is accommodated between the film sheet 30 and the detecting body 10. Accordingly, the sliding ball 50 can be displaced when the film sheet 30 is deformed, and the dust 3 adhering to the film sheet (outer side surface) is dropped.
請續參照圖6及圖7，係為本發明之雷達波物位計的又一實施方式。於本實施例中，該雷達波物位計1更包括一電磁閥60；又，該電磁閥60係控制該工作氣體2進出該輸氣通道11。更具體而言，該工作氣體2及外部氣體之間會形成壓力差，此壓力差會造成該薄膜片30產生震動，並將附著在該薄膜片30上(外側面)的粉塵3甩落，藉此達到清潔該薄膜片30的功能。 Referring to FIG. 6 and FIG. 7 again, it is still another embodiment of the radar wave level gauge of the present invention. In the embodiment, the radar wave level gauge 1 further includes a solenoid valve 60; in addition, the solenoid valve 60 controls the working gas 2 to enter and exit the gas passage 11. More specifically, a pressure difference is formed between the working gas 2 and the outside air, and the pressure difference causes the film sheet 30 to vibrate, and the dust 3 attached to the film sheet 30 (outer side surface) is collapsed. Thereby, the function of cleaning the film sheet 30 is achieved.
請續參照圖8，係分別為本發明之雷達波物位計的第二實施例。於本實施例中，雷達波物位計1a包括一偵測本體10a、一天線本體20a及一薄膜片30a。該偵測本體10a具有能夠發射感測訊號及接收反射訊號的一控制電路板(圖未示)。又，該天線本體20a一端係連接該偵測本體10a。該薄膜片30a結合在該天線本體20a上，並遮蓋該天線本體20a的另一端。 Referring to FIG. 8 again, it is a second embodiment of the radar wave level meter of the present invention. In this embodiment, the radar wave level gauge 1a includes a detecting body 10a, an antenna body 20a, and a film sheet 30a. The detecting body 10a has a control circuit board (not shown) capable of transmitting a sensing signal and receiving a reflected signal. Moreover, one end of the antenna body 20a is connected to the detecting body 10a. The film sheet 30a is bonded to the antenna body 20a and covers the other end of the antenna body 20a.
較佳地，該雷達波物位計1a更包含一天線透鏡40a。該天線透鏡40a係位於該天線本體20a與該薄膜片30a之間。該天線透鏡40a結合在該天線本體20上，並受該薄膜片30a遮蓋。 Preferably, the radar wave level gauge 1a further includes an antenna lens 40a. The antenna lens 40a is located between the antenna body 20a and the film sheet 30a. The antenna lens 40a is coupled to the antenna body 20 and is covered by the film sheet 30a.
本實施例相較於前一實施例不同的地方在於該偵測本體10a並未設置有輸氣通道，也就是，該雷達波物位計1a並未配合工作氣體使用。實際使用時， 外部氣流通過該薄膜片30a的外側面時，氣流能夠帶動該薄膜片30a產生變形，並能夠令附著在該薄膜片30a上的粉塵3掉落。 The difference between this embodiment and the previous embodiment is that the detecting body 10a is not provided with a gas passage, that is, the radar wave level gauge 1a is not used with the working gas. In actual use, When the external airflow passes through the outer side surface of the film sheet 30a, the air current can cause the film sheet 30a to be deformed, and the dust 3 attached to the film sheet 30a can be dropped.
以上所述僅為本發明之較佳實施例，非用以定本發明之專利範圍，其他運用本發明之專利精神之等效變化，均應俱屬本發明之專利範圍。 The above description is only the preferred embodiment of the present invention, and is not intended to limit the scope of the invention, and other equivalent variations of the patent spirit of the present invention are all within the scope of the invention.
