Technical Field
[0001] The present application relates to the technical field of water pumps, and in particular to a pump casing of a submersible pump. Background Art
[0002] A submersible pump is a device that dives into a liquid to pump water. The motor drives the impeller to rotate, which in turn drives the liquid in the pump and uses centrifugal force to bring the liquid into the outlet pipe, thereby achieving the purpose of pumping water. The submersible pump controls the start and stop of the motor through a float switch. When the float sinks to a certain height as the liquid level drops, a signal is sent to control the motor of the submersible pump to stop.
[0003] In existing vertical submersible pumps, the power connection column for the external power supply and the float connection column for connecting the float switch are both arranged on the top of the top shell. At the same time, in order to facilitate the user's carrying, the handle of the vertical submersible pump is also arranged on the top. This makes it easy for the user to bump into the power connection column or the float connection column when holding the handle, thereby causing poor contact of the external power supply or the float switch, affecting the normal use of the submersible pump.

[0025] like Figure 2 As shown, the top shell 1 includes an inner shell 12 and an outer shell 11. The inner shell 12 is a cylindrical structure. The outer shell 11 is sleeved on the outer periphery of the inner shell 12 and is integrally injection molded with the inner shell 12. The length of the outer shell 11 is smaller than the length of the inner shell 12.
[0026] The pump body 2 is a cylindrical structure, and the cross-sectional dimensions of the pump body 2 match the outer shell 11 . The pump body 2 is formed with a mounting channel 21 , and the inner wall of the mounting channel 21 is formed with an annular mounting groove 22 , which matches the inner shell 12 .
[0027] The outer shell 11 is connected to one end of the pump body 2 by screws, and the inner shell 12 is embedded in the installation groove 22. A space for installing core components such as the rotor and bearings is formed between the inner shell 12 and the installation channel 21.
[0028] In this way, the liquid in the pump body 2 is not easily communicated with the liquid outside the pump body 2 through the gap installed between the pump body 2 and the top shell 1, so that the flow direction of the liquid inside the pump body 2 is not easily affected, thereby ensuring the efficiency of the submersible pump in lifting water.
[0029] The handle 4 is connected to the top shell 1 and includes a gripping portion 42 and a fixing portion 43. The gripping portion 42 is an annular structure. The gripping portion 42 is arranged on the periphery of the fixing portion 43 and forms a first inclination angle of an acute angle with the top shell 1. The fixing portion 43 is connected to the top shell 1, and a through opening 41 is formed between the gripping portion 42 and the fixing portion 43.
[0030] Specifically, the holding portion 42 and the fixing portion 43 are integrally injection molded, the holding portion 42 is an elliptical ring structure or a circular ring structure, the fixing portion 43 is a semicircular structure or a semi-elliptical structure that matches the curvature of the holding portion 42, and is arranged on the inner circumference of the holding portion 42, and forms a through opening 41 with the holding portion 42, and the through opening 41 is a semicircular structure or a semi-elliptical structure.
[0031] A groove 13 is formed at the top of the top shell 1. The groove 13 is a U-shaped groove and is located below the through-opening 41.

The angle of the second inclination angle is the same as the angle of the first inclination angle. The second groove wall 132 is an arc-shaped structure.
[0032] The height of the middle portion of the bottom 133 of the groove 13 is higher than that of the two ends, so that water is not easily accumulated in the groove 13 during the lifting process of the submersible pump, and there is enough space between the grip portion 42 and the groove 13 for the user to hold.
[0033] like Figure 2As shown, the clamping block 5 is formed with a first inclined surface 51, a second inclined surface 52 and a stop block 53. The inclination angles of the first inclined surface 51 and the second inclined surface 52 are the same as the angle of the first inclination angle. The first inclined surface 51 is parallel to the second inclined surface 52. The stop block 53 is located on the first inclined surface 51. The clamping block 5 is clamped between the holding portion 42 and the first groove wall 131. Specifically, the first inclined surface 51 fits with the first groove wall 131 and abuts against the first groove wall 131. The stop block 53 is clamped at the top end of the first groove wall 131. The second inclined surface 52 fits with the holding portion 42 and abuts against the holding portion 42.
[0034] The power connection post 7 and the float connection post 6 are arranged in the groove 13, adjacent to the clamping block 5, below the through port 41, and within the inner ring of the holding portion 42.

[0036] The float connection wire 82 and the top shell 1 are connected through a connecting member 9. The connecting member 9 includes a seat body 91 and a connecting body 92. The seat body 91 is arranged on the top shell 1. The connecting body 92 is provided with a through hole along the length direction of the float connection wire 82. A plurality of protrusions 921 are arranged on the inner circumference of the through hole. The plurality of protrusions 921 face the midline of the through hole. The float connection wire 82 is inserted into the through hole. The plurality of protrusions 921 abut against the float connection wire 82. The connecting body 92 is hung on the seat body 91. Specifically, a hanging groove is arranged along the length direction of the float connection wire 82.
