The rear frame of the motor has a junction box. If the chemical liquid belonging to strong acid or alkali is leaking, the motor middle frame, the motor rear frame and the junction box may be corroded by the chemical liquid.

In addition, the Taiwan Patent No. I381100 patent case has the same problem.

Accordingly, it is an object of the present invention to provide a pump housing having a waterproof cover that shields the components of the pump.

Therefore, the pump casing having the waterproof cover is covered on the outside of a pump, the pump includes a motor unit, a front cover member mounted on one side of the motor unit, and a side mounted on the motor unit along an axis The back cover member has a junction box, and the pump housing comprises a base and a waterproof cover. The base is made of a plastic material, has a main section wrapped around the outside of the motor unit, and an extension connected to the main section and corresponding to the back cover, the extension has an opposite a distal end portion of the main section, and a plurality of engaging portions spaced apart from the end portion, the waterproof cover is made of a plastic material, detachably connected to the extending portion, and has a overlapping portion with the end portion a sleeve portion, a side edge portion opposite to the sleeve portion along the axis, and a plurality of engaging portions disposed on the sleeve portion and interlacing with the fastening portions, the waterproof cover being coupled to the extension portion In the segment, the junction box does not protrude from the side edge portion.

The utility model has the advantages that the pump casing can be resistant to strong acid and alkali, and the waterproof cover can be disassembled relative to the base, thereby facilitating assembly and maintenance of the junction box.

Referring to FIG. 1 , FIG. 2 and FIG. 3 , an embodiment of a pump casing with a waterproof cover is coated on the outside of a canned magnetic pump 100. The canned magnetic pump 100 includes a motor unit 10 and is mounted on a front cover member 20 on one side of the motor unit 10, and a rear cover member 30 mounted on one side of the motor unit 10 along an axis L. The motor unit 10 has a positioning seat 11 including a mounting bracket 11 thereon. The inner casing 12, a stator 13 disposed between the casing 12 and the positioning seat 11, a rotor 14 mounted inside the casing 12, and an impeller 15 connected to the rotor 14. The rear cover member 30 has a junction box 31 including a base 40 and a waterproof cover 50.

The base 40 has a main section 41 covering the positioning seat 11 of the motor unit 10 and the outside of the stator 13, and an extension 42 connected to the main section 41 and corresponding to the rear cover member 30, The extension 42 has an inverted U-shape perpendicular to the contour of the axis L, and is formed by a top plate portion 421 and two side plate portions 422 which are oppositely disposed and coupled to the side edges of the top plate portion 421. The extension portion 42 further has The end portion 423 of the main section 41 and the plurality of fastening portions 424 spaced apart from the end portion 423, the number of the fastening portions 424 is three, respectively, from the top plate portion 421, the side panels The inner side surface of the portion 422 is recessed in a concave shape.

The waterproof cover 50 is detachably connected to the extending portion 42. The waterproof cover 50 is also inverted U-shaped in a contour shape perpendicular to the axis L, and is disposed opposite to and coupled to the top wall portion 51 and the top wall portion 51. The side wall portions 52 of the side edges of the 51 are formed together, and have a sleeve portion 53 overlapping the end portion 21, a groove 54 disposed around the outside of the sleeve portion 53, and a direction L along the axis L The side edge portion 55 of the fitting portion 54 and the plurality of engaging portions 56 that are connected to the fitting portion 53 and are engageable with the engaging portions 424. The number of the engaging portions 56 is three, which are respectively disposed on the top wall portion 51 and the side wall portions 52. The engaging portions 56 are in the shape of a hook and each has a connection connected to the fitting portion 53. The end portion 561 and a hook portion 562 opposite to the connecting end portion 561 and embedded in the fastening portions 424.

In order to further understand the functions, technical means, and expected effects of the cooperation of the various components of the present invention, it is to be noted that the following is a more in-depth and specific understanding of the present invention.

As shown in FIG. 4, when the canned magnetic pump 100 is integrally assembled and the base 40 is mounted and positioned relative to the canned magnetic pump 100, the main section 41 of the base 40 is covered by the base. The positioning base 11 of the motor unit 10 and the outside of the stator 13 and the plastic material of the base 40 can be used to generate strong acid and alkali resistance, and the service life of the canned magnetic pump 100 can be prolonged. And when the waterproof cover 50 is assembled to the rear side of the base 40, the waterproof cover 50 can shield the junction box 31 of the rear cover member 30, and the junction box 31 does not protrude from the side edge portion 55.

And the waterproof cover 50 is detachably connected to the extension portion 42. In addition to extending the protection range of the base 10, the contour of the base 40 and the waterproof cover 50 perpendicular to the axis L is inverted. The U shape can provide a more comprehensive protection for the junction box 31 of the back cover member 30.

In addition, the end portion 423 of the base 40 is sleeved in the recess 54 and the end portion 423 is firmly lapped to the outside of the sleeve portion 53. The waterproof cover 50 is equivalent to the socket 40. The fastening cover 50 and the fastening portions 424 are interlocked with each other, so that the waterproof cover 50 can be disassembled and disassembled at any time with respect to the base 40. .

When the rear cover member 30 or the junction box 31 is to be disassembled and repaired, the operator can easily detach the card engaging portion 56 from the fastening portions 424, and the waterproof cover 50 is self-contained. When the seat 40 is detached, the junction box 31 is exposed outside the end portion 423 of the base 40, and the operation of repairing or detaching the junction box 31 can be performed in a sufficient space.

In summary, the pump casing with the waterproof cover of the present invention has a simple overall structure and a relatively easy assembly and assembly, and can indeed achieve the purpose of the present invention.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
