UTILITY MODEL CONTENTS

[0006] In view of the above deficiencies in the related art, the purpose is to provide a condensing pump to solve the technical problems that in the related art, the condensate flow is blocked, potential energy of the condensate flow is lost, the condensate cannot be smoothly discharged, and the drainage performance is relatively poor;

[0007] The technical solution to achieve the purpose is: a condensing pump, comprising: a pump body; a motor assembly connected to the pump body; an impeller connected to the motor assembly and rotated by the motor assembly; and a pump cover connected to one end of the pump body and covering the impeller, and the pump cover has a liquid inlet; further comprising: a liquid storage cavity for discharging condensate, the liquid storage cavity comprising:

[0008] A blocking body connected to the pump body, the blocking body having a flat surface and a liquid outlet channel;

[0009] The plane and the pump body have an inner space, and the inner space is communicated with a liquid outlet on the pump body;

[0010] One end of the liquid outlet is connected with the pump body, and the other end extends away from the pump body.

[0011] One end of the liquid outlet is connected with the pump body, and the other end extends away from the pump body.

[0012] Further, the plane is a horizontal plane.

[0013] Further, the first gap is a longitudinal gap distance A.

[0014] The longitudinal gap distance A is the distance between one end of the liquid outlet and one end of the liquid outlet.

[0015] Further, the liquid outlet and the liquid outlet also have a second gap;

[0016] The second gap is a transverse gap distance B.

[0017] The transverse gap distance B is the distance between the side wall of the liquid outlet and the side wall of the liquid outlet, and the two side walls are adjacent side walls.

[0018] Further, the longitudinal gap distance A is greater than or equal to 1mm;

[0019] The longitudinal gap distance A is less than or equal to 1 / 2 of the height dimension C of the inner space.

[0020] The height dimension C is also the distance between the plane and one end of the liquid outlet.

[0021] Further, the longitudinal gap distance A is 3mm.

[0022] Further, the transverse gap distance B is 0-33mm.

[0023] Further, the transverse gap distance B is 27mm.

[0029] The baffle is connected to the pump body and has a plane and a liquid outlet channel; there is an inner space between the plane and the pump body, and the inner space is connected to the liquid outlet on the pump body; one end of the liquid outlet channel is set in the inner space, and there is a first gap between the liquid outlet channel and the liquid outlet.

[0030] When the motor assembly operates, the impeller rotates in conjunction with it. Condensate enters through the inlet on the pump cover, flows into the inner space through the outlet on the pump body, and is then discharged through the outlet channel. Since the flat surface does not obstruct the smooth flow of condensate, and there is a first gap between the outlet channel and the outlet, the condensate can flow smoothly into the outlet channel through the first gap, resulting in relatively good drainage performance. Furthermore, when the power is off, the motor assembly stops operating, and some condensate remains in the inner space, sealing one end of the outlet channel. Water vapor is blocked in the inner space, preventing water vapor from escaping through the outlet channel.

[0031] This overcomes the technical problem of blocked condensate flow, resulting in potential energy loss and poor drainage performance. It achieves the technical effect of smooth condensate flow and relatively good drainage performance, and is practical. Attached Figure Description

[0038] In order to make the content easier to be clearly understood, the following is further described in detail according to specific embodiments and in combination with the accompanying drawings;

[0039] A condensate pump solves the technical problem that in the related art, the condensate flow is blocked, resulting in potential energy loss of the condensate flow, and the condensate cannot be smoothly discharged, and the drainage performance is relatively poor, and can be manufactured and used, and achieves the positive effect that the condensate flow can be smoothly discharged, and the drainage performance is relatively good, and the overall idea is as follows:

[0040] An embodiment:

[0041] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 5 A condensate pump includes: a pump body 10; a motor assembly 20 connected to the pump body 10; an impeller 30 connected to the motor assembly 20 and rotated by the motor assembly 20; and a pump cover 40 connected to one end of the pump body 10, covering the impeller 30, and the pump cover 40 has a liquid inlet 41, and further includes:

[0042] A liquid storage cavity for discharging condensate, the liquid storage cavity includes:

[0043] A block body 50 connected to the pump body 10, the block body 50 has a flat surface 51 and a liquid outlet channel 52;

[0044] The flat surface 51 and the pump body 10 have an inner space 60, and the inner space 60 is in communication with the drainage port 11 on the pump body 10;

[0045] One end of the drainage port 11 is connected to the pump body 10, and has the inner space 60 between the flat surface 51 and the pump body 10, and the other end extends away from the pump body 10;

[0046] One end of the liquid outlet channel 52 is arranged in the inner space 60, and the liquid outlet channel 52 has a first gap between the liquid outlet channel 52 and the drainage port 11;

[0047] Specifically, in implementation, the motor assembly 20 operates, the linkage impeller 30 rotates, the condensed water enters the inner space 60 through the liquid inlet 41 on the pump cover 40 and the liquid outlet 11 on the pump body 10, and then is discharged through the liquid outlet channel 52. Since the plane 51 does not block the smooth flow of the condensed water, and the first gap exists between the liquid outlet channel 52 and the liquid outlet 11, the condensed water flow can smoothly enter the liquid outlet channel 52 from the first gap, and the drainage performance is relatively good. When power is off, the motor assembly 20 stops operating, part of the condensed water is retained in the inner space 60, one end of the liquid outlet channel 52 is sealed, and water vapor is blocked in the inner space 60, so that water vapor does not escape along the liquid outlet channel 52.

[0048] Another embodiment is shown in FIG. 6.

[0049] As shown in FIG. 1, the pump body 10, the motor assembly 20, the impeller 30, and the pump cover 40 are common structures in the prior art. Figure 1 Figure 2 Figure 3 In implementation, the plane 51 is a horizontal plane, which does not block the smooth flow of the condensed water.

[0050] The motor assembly 20 includes a stator connected in a stator cavity on the pump body 10 and a rotor connected in a rotor cavity on the pump body 10.

[0051] The motor assembly 20 is used to generate rotary power, and the linkage impeller 30 rotates. The pump cover 40 is connected with the pump body 10 by screws. When the motor assembly 20 operates, the condensed water enters along the liquid inlet 41.

[0052] Those skilled in the art can directly and without doubt know how to set the pump body 10, the motor assembly 20, the impeller 30, and the pump cover 40 after seeing the disclosure, without creative labor and excessive experiments.

[0053] Another embodiment is shown in FIG. 6.

[0054] As shown in FIG. 1, the pump body 10, the motor assembly 20, the impeller 30, and the pump cover 40 are common structures in the prior art. Figure 1 Figure 2 Figure 3 Figure 4 In implementation, the plane 51 is a horizontal plane, which does not block the smooth flow of the condensed water.

[0055] The first gap is a longitudinal gap distance A. The longitudinal gap distance A is a distance between one end of the liquid outlet channel 52 and one end of the liquid outlet 11. The longitudinal gap distance A is greater than or equal to 1 mm. The longitudinal gap distance A is less than 1 / 2 of a height dimension C of the inner space 60. The height dimension C is a distance between the plane 51 and one end of the liquid outlet 11. The longitudinal gap distance A is 3 mm.

[0056] ​​​​​The liquid outlet channel 52 and the liquid discharge port 11 also have a second gap; the second gap is a transverse gap distance B; the transverse gap distance B is the distance between the side wall of the liquid outlet channel 52 and the side wall of the liquid discharge port 11, and the two side walls are adjacent side walls; the transverse gap distance B is 0-33mm; the transverse gap distance B is 27mm;

[0057] The control of the distance size not only enables the condensate water flow to be smoothly discharged from the liquid outlet channel 52, but also enables the volume of the inner space 60 to be relatively large, which is conducive to accommodating the condensate water and water vapor, and the water vapor cannot escape along the liquid outlet channel 52;

[0058] The blocking body 50 includes a connecting body 50-1 connected with the pump body 10 and forming the inner space 60 with the pump body 10, and the connecting body 50-1 has the flat surface 51 thereon;

[0059] The connecting body 50-1 is integrally formed with the liquid outlet channel 52, and one end of the liquid outlet channel 52 is arranged in the inner space 60, and the other end protrudes from the connecting body 50-1;

[0060] The connecting body 50-1 has a substantially T-shaped structure, and is inserted between the pump body 10 and connected with the pump body 10 by screws, so that the assembly is convenient;

[0061] The inner space 60 is arranged, which is conducive to accommodating the condensate water and water vapor, and the condensate water flow can be smoothly discharged. When power is off, the motor assembly 20 stops working, and part of the condensate water will be retained in the inner space 60, sealing one end of the liquid outlet channel 52. The water vapor floats and contacts the flat surface 51, and is blocked in the inner space 60, so that the water vapor cannot escape along the liquid outlet channel 52;

[0062] Another embodiment:

[0063] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 At least one sealing member 70 is arranged in the annular groove 50-11 on the connecting body 50-1, and is used for sealing the blocking body 50 and the pump body 10;

[0064] The sealing member 70 is a sealing ring made of rubber, which ensures the sealing property and prevents the condensate water and water vapor from leaking from the connection between the blocking body 50 and the pump body 10;

[0065] The working principle is as follows: the motor assembly 20 is in action, the linkage impeller 30 rotates, the condensed water enters the liquid inlet 41 on the pump cover 40, enters the inner space 60 along the liquid outlet 11 on the pump body 10, and is discharged from the liquid outlet passage 52. Since the plane 51 does not block the smooth flow of condensed water, and the liquid outlet passage 52 and the liquid outlet 11 have a first gap, the condensed water flow can smoothly enter the liquid outlet passage 52 from the first gap, and the drainage performance is relatively good. When power is off, the motor assembly 20 stops working, part of the condensed water will be retained in the inner space 60, sealing one end of the liquid outlet passage 52, and the water vapor is blocked in the inner space 60, and no water vapor will escape along the liquid outlet passage 52;
