It is believed that a deeper and specific understanding of the present invention can be obtained from this.

再如圖2及圖3所示，當本新型具後蓋護罩防漏強化的罐裝磁力泵整體組裝完成時，該前蓋60利用多數螺絲鎖固於該基座10的主盤件11，使得呈階級狀的第一側面111與該內端面61呈凹凸嵌套，也就是說，利用該內圈段115相對於該外圈段116朝外部凸出、該內環段611相對於該外環段612朝內部凹入，以及該延伸盤部42與該法蘭312氣密夾制於該內圈段115與該內環段611之間、該法蘭312周緣及該延伸盤部42周緣抵止於該第二肩部613的作用，可使得該延伸盤部42與該法蘭312的定位性、密封性佳。As shown in Figures 2 and 3, when the integral assembly of the canned magnetic pump with a rear cover shield and enhanced leak-proofness is completed, the front cover 60 is locked to the main plate 11 of the base 10 with a plurality of screws. , So that the step-shaped first side surface 111 and the inner end surface 61 are concave-convex nested, that is to say, the inner ring segment 115 is used to protrude outward relative to the outer ring segment 116, and the inner ring segment 611 is relative to the The outer ring segment 612 is recessed toward the inside, and the extension disc portion 42 and the flange 312 are airtightly sandwiched between the inner ring segment 115 and the inner ring segment 611, the periphery of the flange 312 and the extension disc portion 42 The function of the peripheral edge against the second shoulder 613 can make the positioning and sealing of the extension plate 42 and the flange 312 better.

再利用，該第一防漏元件71安裝於該內圈段115與該延伸盤部42之間，且該第一防漏元件71嵌套於該第一環槽118中的作用，即使當罐裝磁力泵使用一段時間後，經常與化學藥液接觸的殼體31的主筒部311有產生裂損，且化學藥液滲漏至該殼體31與該後蓋護罩40之間，利用該第一防漏元件71的設置可防止化學藥液滲漏至該定子32，可以產生第一道防滲漏。且也利用該第二防漏元件72裝設於該外環段612與該外圈段116之間，使得該內端面61與該第一側面111之間保持氣(水)密，可以產生第二道防滲漏。Reuse, the first leak-proof element 71 is installed between the inner ring section 115 and the extension disc portion 42, and the first leak-proof element 71 is nested in the first ring groove 118, even when the tank After using the magnetic pump for a period of time, the main cylinder part 311 of the casing 31 that is often in contact with chemical liquids is cracked, and the chemical liquid leaks between the casing 31 and the back cover 40, The arrangement of the first anti-leakage element 71 can prevent the chemical liquid from leaking to the stator 32 and can produce a first anti-leakage. Moreover, the second leak-proof element 72 is also installed between the outer ring section 612 and the outer ring section 116, so that the inner end surface 61 and the first side surface 111 are kept air (water) tight, which can produce a The second anti-leakage.

再者，因為該殼體31的法蘭312與該後蓋護罩40的延伸盤部42被夾制於該前蓋60與該第一側面111之間，如此一來，該馬達單元30的殼體31的法蘭312，以及該後蓋護罩40的延伸盤部42相對於該基座10、該定位座20產生定位，並利用該第三防漏元件73夾制於該法蘭312與該內環段611之間，可確保該前蓋60、該法蘭312，以及該基座10的接合處產生氣(水)密，並產生較佳的防滲漏效果。Furthermore, because the flange 312 of the housing 31 and the extension plate 42 of the rear cover shield 40 are sandwiched between the front cover 60 and the first side surface 111, as a result, the motor unit 30 The flange 312 of the housing 31 and the extension plate 42 of the rear cover 40 are positioned relative to the base 10 and the positioning seat 20, and are clamped to the flange 312 by the third leak-proof element 73 Between the inner ring segment 611 and the inner ring segment 611, it can be ensured that the joints of the front cover 60, the flange 312, and the base 10 are air (water) tight, and produce a better anti-leakage effect.

又利用呈階級狀的第一側面111與該內端面61呈凹凸嵌套，且利用該內圈段115相對於該外圈段116朝外部凸出、該內環段611相對於該外環段612朝內部凹入的作用，以及該第一防漏元件71、該第二防漏元件72與該第三防漏元件73的設置，也可有效地防止自過濾桶滴落的化學藥液而滲漏至該定子32內部，因此，可以延長馬達單元30的使用壽命。Furthermore, the step-shaped first side surface 111 is concave-convex nested with the inner end surface 61, and the inner ring segment 115 is used to protrude outward relative to the outer ring segment 116, and the inner ring segment 611 is relative to the outer ring segment. 612 is recessed toward the inside, and the arrangement of the first anti-leak element 71, the second anti-leak element 72 and the third anti-leak element 73 can also effectively prevent the chemical liquid dripping from the filter tank from being damaged. Leakage into the stator 32, therefore, the service life of the motor unit 30 can be prolonged.

再者，利用呈階級狀的第一側面111與該內端面61呈凹凸嵌套，可以形成多轉折結構，可以在該法蘭312與該延伸盤部42抵接處產生較佳的阻漏效果。Furthermore, the step-shaped first side surface 111 and the inner end surface 61 are concave and convexly nested, which can form a multi-turn structure, which can produce a better leakage prevention effect at the abutment of the flange 312 and the extension plate 42 .

綜上所述，本新型具後蓋護罩防漏強化的罐裝磁力泵，整體結構簡單、製造組配容易，且可達到較佳的阻漏效果，確實能達成本新型的目的。To sum up, the new canned magnetic pump with enhanced leakage prevention of the back cover has a simple overall structure, easy manufacturing and assembly, and can achieve better leakage resistance, and can indeed achieve the purpose of new cost.

惟以上所述者，僅為本新型的實施例而已，當不能以此限定本新型實施的範圍，凡是依本新型申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本新型專利涵蓋的範圍內。However, the above-mentioned are only examples of the present model.
