為供進一步瞭解本發明各元件配合所產生的作用、運用技術手段，以及所預期達成的功效，將再說明如下，相信當可由此而對本發明有更深入且具體的瞭解。 In order to further understand the functions produced by the cooperation of the various components of the present invention, the technical means used, and the expected effects, the following will be described again, and it is believed that a deeper and specific understanding of the present invention can be obtained from this.

再如圖2至圖4所示，當罐裝磁力泵整體組裝完成後，該定位座20設置於該定子32外部，該基座10也設置於該定位座20外部。該泵前蓋40鎖固於該基座10的第一端面11，該後蓋50鎖固於該定位座20且相對於該基座10產生定位，且該內側面51抵靠於該第三抵靠部146，該後蓋50也透過該防漏環62而氣密地抵接於該定 子32的第二側面22。 As shown in FIGS. 2 to 4 , after the overall assembly of the canned magnetic pump is completed, the positioning seat 20 is disposed outside the stator 32 , and the base 10 is also disposed outside the positioning seat 20 . The pump front cover 40 is locked on the first end surface 11 of the base 10, the rear cover 50 is locked on the positioning seat 20 and positioned relative to the base 10, and the inner side 51 is against the third The abutting portion 146, the rear cover 50 is also airtightly abutted against the fixed portion through the leakproof ring 62. The second side 22 of the child 32.

當該馬達單元30的定子32通入電源時，能驅動該轉子33產生轉動，且該轉子33同步帶動該葉輪34轉動，則由該泵前蓋40前側引入的液體再被該葉輪34朝該泵前蓋40外部汲送，且達到泵送液體的目的。 When the stator 32 of the motor unit 30 is powered on, it can drive the rotor 33 to rotate, and the rotor 33 synchronously drives the impeller 34 to rotate, then the liquid introduced from the front side of the pump front cover 40 is then driven by the impeller 34 toward the The pump front cover 40 is externally pumped and serves the purpose of pumping liquid.

且，如圖3及圖4所示，利用該環形凸肋53與該內側面51共同界定而成的內導熱空間54，以及該內導熱空間54相鄰於該定子32的作用，則該馬達單元30運轉中所產生熱能可由該定子32散發至該內導熱空間54，並由該後蓋50吸熱後，再由該等散熱鰭片57傳遞至外部，且可產生較佳的散熱效果，可延長該馬達單元30的使用壽命。 And, as shown in FIG. 3 and FIG. 4 , using the inner heat conduction space 54 defined by the annular rib 53 and the inner surface 51 together, and the effect that the inner heat conduction space 54 is adjacent to the stator 32 , the motor The heat energy generated during the operation of the unit 30 can be dissipated from the stator 32 to the inner heat conduction space 54, and after being absorbed by the rear cover 50, it is then transferred to the outside by the heat dissipation fins 57, and can produce better heat dissipation effect. The service life of the motor unit 30 is extended.

另外，也利用該等凸肋56凸設於該外環面533且排列呈輻射狀地伸設於該外導熱空間55，則可增加該後蓋50的散熱面積。也利用該環形凸肋53的環端面531氣密抵靠於該定位座20的第二側面22，以及該等凸肋56的設置，可增加與該定位座20的接觸面積，且可提升該定位座20與該後蓋50之間的支撐性，使得該後蓋50可穩固地相對於該定位座20產生定位，則該定位座20沿軸向穩固定位於該基座10與該後蓋50之間，可強化該馬達單元30啟動及運轉的穩定性。 In addition, the protruding ribs 56 protrude from the outer ring surface 533 and extend radially from the outer heat conduction space 55 , so that the heat dissipation area of the rear cover 50 can be increased. The ring end surface 531 of the annular convex rib 53 is also used to airtightly abut against the second side 22 of the positioning seat 20, and the setting of the convex ribs 56 can increase the contact area with the positioning seat 20, and can improve the position of the positioning seat 20. The support between the positioning seat 20 and the rear cover 50 enables the rear cover 50 to be stably positioned relative to the positioning seat 20, and the positioning seat 20 is stably fixed between the base 10 and the rear cover in the axial direction. Between 50, the stability of starting and running of the motor unit 30 can be enhanced.

再者，利用該環形凸肋53的環端面531氣密抵靠於該定 位座20的第二側面22及該防漏環62上，可以使得該定子32產生較佳的防漏性。 Furthermore, the ring end surface 531 of the annular convex rib 53 is used to abut against the fixed ring in an airtight manner. The second side 22 of the seat 20 and the anti-leakage ring 62 can make the stator 32 have a better anti-leakage performance.

另外，利用該等凸肋56排列呈輻射狀地凸設於該外環面533，除了具有散熱鰭片的功能外，更具有節省原料、減輕該後蓋50及整體重量的效果。 In addition, the protruding ribs 56 arranged radially on the outer ring surface 533 not only have the function of cooling fins, but also have the effect of saving raw materials and reducing the weight of the rear cover 50 and the whole.

綜上所述，本發明具加強散熱效果後蓋之罐裝磁力泵，整體結構簡單、製造組配容易，且可達到較佳的散熱效果，確實能達成本發明的目的。 To sum up, the present invention has a canned magnetic pump with a back cover that enhances the heat dissipation effect, has a simple overall structure, is easy to manufacture and assemble, and can achieve a better heat dissipation effect, and can indeed achieve the purpose of the present invention.

惟以上所述者，僅為本發明的實施例而已，當不能以此限定本發明實施的範圍，凡是依本發明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，皆仍屬本發明專利涵蓋的範圍內。 But the above-mentioned ones are only embodiments of the present invention, and should not limit the scope of the present invention. All simple equivalent changes and modifications made according to the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention.
