[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] The present utility model provides a pump housing with a heat - dissipation structure as Figures 1-4 shown, which includes a pump housing body 1 and a motor 7 arranged inside the pump housing body 1. One side of the surface of the pump housing body 1 is fixedly connected with a water inlet pipe 4, the top surface of the pump housing body 1 is fixedly connected with a water outlet pipe 5, and one side of the surface of the water outlet pipe 5 is fixedly connected with a water distribution pipe 6. The water distribution pipe 6 can send out a part of the water flowing through the water outlet pipe 5 without affecting the normal use of the device. One end of the water distribution pipe 6 is provided with a refrigeration component 2 that can cool the water sent by the water distribution pipe 6. Inside the pump housing body 1, there is a heat - dissipation component 3 that can send the water cooled by the refrigeration component 2 into the inside of the pump housing body 1 to cool the motor 7 inside the pump housing body 1. Through the water distribution pipe 6, a part of the water can be separated and enter the inside of the refrigeration component 2 during the use of the device, then the water is refrigerated by the refrigeration component 2, and finally the refrigerated water is sent into the inside of the pump housing body 1 through the heat - dissipation component 3, thereby reducing the temperature of the pump housing body 1, making the motor 7 in a space with a relatively low temperature, and solving the problem that the motor 7 may become hot during long - term use and affect its service life.

[0022] Such as Figure 3 and Figure 4As shown in the figure, the refrigeration component 2 includes a refrigeration box 201. The bottom surface of the refrigeration box 201 is fixedly connected to the top surface of the pump housing body 1. One side of the surface of the refrigeration box 201 is fixedly connected to one end of the water distribution pipe 6 away from the water outlet pipe 5. The refrigeration component 2 further includes a semiconductor refrigeration sheet 202, which is fixedly connected to the inner wall of the refrigeration box 201. A conduction sealing plate 203 is fixedly connected to the bottom surface of the semiconductor refrigeration sheet 202. The conduction sealing plate 203 can transfer the temperature while forming a seal to prevent water from directly contacting the semiconductor refrigeration sheet 202. Two conduction rods 204 are fixedly connected to the bottom surface of the conduction sealing plate 203. The conduction rods 204 can directly contact the water to cool the water. A heat sink 205 is fixedly connected to the top surface of the semiconductor refrigeration sheet 202. The heat sink 205 can dissipate heat from the semiconductor refrigeration sheet 202 to prevent the semiconductor refrigeration sheet 202 from getting hot.

[0023] As Figures 1-3 shown, the heat dissipation component 3 includes a first cavity 301 and a second cavity 303 opened in the pump housing body 1. Opposite sides of the inner walls of the first cavity 301 and the second cavity 303 are respectively fixedly connected with a first heat dissipation pipe 302 and a second heat dissipation pipe 304. One ends of the first heat dissipation pipe 302 and the second heat dissipation pipe 304 respectively penetrate through one side of the inner walls of the first cavity 301 and the second cavity 303 and extend to the surface of the pump housing body 1. The heat dissipation component 3 further includes a fixing groove 305, which is opened in the pump housing body 1. The fixing groove 305 is respectively communicated with the inside of the first cavity 301 and the second cavity 303. The heat dissipation component 3 further includes a shunt pipe 306, which can send water into the first heat dissipation pipe 302 and the second heat dissipation pipe 304. The surface of the shunt pipe 306 is fixedly connected to the inner wall of the fixing groove 305. Two ends of the shunt pipe 306 respectively extend into the first cavity 301 and the second cavity 303 and are respectively connected to the first heat dissipation pipe 302 and the second heat dissipation pipe 304. A water guide pipe 307 is fixedly connected to the top surface of the shunt pipe 306. The top end of the water guide pipe 307 extends into the refrigeration box 201.

[0024] As Figure 3 shown, a heat dissipation port 8 is opened on the top surface of the refrigeration box 201. The heat dissipation port 8 can dissipate heat from the semiconductor refrigeration sheet 202 to prevent the semiconductor refrigeration sheet 202 from overheating. The heat dissipation port 8 is communicated with the inside of the refrigeration box 201. A dust-proof net 9 is fixedly connected to the inner wall of the heat dissipation port 8. The axis of the fixing groove 305 is perpendicular to the first cavity 301 and the second cavity 303 respectively. The first cavity 301 and the second cavity 303 are parallel to each other.

[0025] Working principle of the utility model: When the device is in use, first connect the water inlet pipe 4 of the device to the position where water needs to be pumped, then start the device, and then the device starts to pump water. Water enters through the water inlet pipe 4 and is discharged through the water outlet pipe 5. At the same time, a small part of the water enters the interior of the refrigeration box 201 through the branch water pipe 6 when it is discharged through the water outlet pipe 5. When the device is started, the semiconductor refrigeration sheet 202 is electrified, and then the semiconductor refrigeration sheet 202 performs refrigeration work. And through the setting of the conduction sealing plate 203 and the conduction rod 204, the temperature inside the refrigeration box 201 can be made relatively low. Then the water entering the interior of the refrigeration box 201 through the branch water pipe 6 comes into contact with the conduction rod 204 on average, and then the conduction rod 204 cools the water inside the refrigeration box 201. As the device continues to operate, continuous water enters the interior of the refrigeration box 201, and then the refrigerated water enters the interior of the shunt pipe 306 through the action of the guide pipe 307. Then the shunt pipe 306 sends the cold water into the interior of the first radiating pipe 302 and the second radiating pipe 304. At this time, since the interiors of the first radiating pipe 302 and the second radiating pipe 304 are both cold water, the relatively low temperature can be conducted to the pump housing body 1, making the overall temperature of the pump housing body 1 relatively low, so as to continuously cool the motor 7 and the internal controller directly, preventing the motor 7 from being damaged due to excessive temperature, which affects the normal use of the device. Finally, the cold water flowing through the first radiating pipe 302 and the second radiating pipe 304 will continue to be discharged back to the water source. The original text highlights the innovative structure and does not elaborate on the prior art too much.

[0026] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
