Detailed Description
In order to explain technical contents and structural features of the present invention in detail, the following description is made with reference to the embodiments and the accompanying drawings.
Referring to fig. 1 to 4, a micro water pump 100 of the present invention includes a pump housing 1, a motor 2, an impeller 3, a water inlet pipe 4, a water outlet pipe 5, a sealing cover 6, a sealing box 7, and a foot pad 8. The water inlet pipe 4 is connected to the side wall of the pump case 1, and the water outlet pipe 5 is connected to the top wall of the pump case 1. The motor 2, the impeller 3 and the sealing cover 6 are all arranged in the pump shell 1. The output of the motor 2 is connected to the impeller 3. The sealing cover 6 has a containing cavity 61, and the containing cavity 61 is respectively communicated with the water inlet pipe 4 and the water outlet pipe 5. The impeller 3 is positioned in the containing cavity 61, and the motor 2 is positioned outside the containing cavity 61. It can be understood that the motor 2 drives the impeller 3 to rotate. When the impeller 3 rotates in the containing cavity 61, a negative pressure is formed at the joint of the impeller and the water inlet pipe 4, and a positive pressure is formed at the joint of the impeller and the water outlet pipe 5, so that the water is forced to enter from the water inlet pipe 4 and flow out from the water outlet pipe 5 by the atmospheric pressure. The sealing cover 6 isolates the impeller 3 from the motor 2, and water is prevented from entering the motor 2 by the sealing cover 6 to affect the operation of the motor 2. The water inlet pipe 4 comprises a vertical pipe 41 and a horizontal pipe 42 which are integrally connected, one end of the vertical pipe 41 is connected with one end of the horizontal pipe 42, the other end of the horizontal pipe 42 is connected with the side wall of the pump shell 1, and a pipe opening 411 of the vertical pipe 41 is arranged downwards. With the spout 411 of the vertical pipe 41 set downward, the spout 411 can be infinitely close to the bottom surface of the water tank, so that water at a low water level can be extracted, and water resources are saved. For example, the water inlet pipe 4 is disposed in an inverted L shape. More specifically, the following:
referring to fig. 1 to 2, the foot pad 8 is disposed around the bottom of the pump housing 1. With the help of the foot pad 8, the micro-water pump 100 of the present invention can be supported on the bottom surface of the water tank. Understandably, the material density of the pump case 1 and the foot pad 8 is greater than the density of water, thereby preventing the micro-water pump 100 of the present invention from floating after the water tank is filled with water.
Referring to fig. 3, the distance d1 between the nozzle 411 of the vertical tube 41 and the bottom surface of the foot pad 8 is 10mm-20 mm. Specifically, in the present embodiment, the distance d1 between the nozzle 411 of the vertical tube 41 and the bottom surface of the foot pad 8 is 15 mm. Preferably, the distance d2 between the nozzle 411 of the vertical pipe 41 and the bottom surface of the pump housing 1 is 1mm to 2 mm. For example, in the present embodiment, the distance d2 between the nozzle 411 of the vertical pipe 41 and the bottom surface of the pump housing 1 is 1.6 mm.
Referring to fig. 6, the water inlet pipe 4 partially extends into the pump casing 1, the sealing cover 6 is provided with a sealing ring 62 which is hermetically connected with the extending water inlet pipe 4, and the sealing ring 62 is sleeved on the water inlet pipe 4.
Referring to fig. 6, the micro water pump 100 of the present invention further includes a seal box 7, the seal box 7 is disposed in the pump case 1, the motor 2 is disposed in the seal box 7, and the impeller 3 is disposed outside the seal box 7. By means of the sealing box 7 and the sealing cover 6, the motor 2 is protected in a double isolation mode, water is prevented from entering the area where the motor 2 is located, and the work of the motor 2 is prevented from being influenced.
Referring to fig. 6, the water inlet pipe 4 is integrally connected with the pump housing 1, but in other embodiments, the water inlet pipe 4 and the pump housing 1 are separately disposed, so the disclosure is not limited thereto. Similarly, the water outlet pipe 5 and the pump housing 1 are separately arranged, and certainly, in other embodiments, the water outlet pipe 5 and the pump housing 1 are integrally connected, so the invention is not limited thereto.
Referring to fig. 1 to 2, the pump housing 1 has a square structure. Of course, in other embodiments, the pump housing 1 may have a cylindrical structure, and thus the invention is not limited thereto.
It can be understood that the micro-pump 100 of the present invention can be applied to a pet drinking fountain or other water tanks with small volume, and is not limited thereto.
The operation principle of the micro water pump 100 of the present invention is explained with reference to the accompanying drawings: when the impeller 3 rotates in the containing cavity 61, a negative pressure is formed at the joint of the impeller and the water inlet pipe 4, and a positive pressure is formed at the joint of the impeller and the water outlet pipe 5, so that the water is forced to enter from the water inlet pipe 4 and flow out from the water outlet pipe 5 by the atmospheric pressure.
Compared with the prior art, the utility model discloses a miniature pump 100 includes vertical pipe 41 and horizontal pipe 42 with the help of inlet tube 4, and the one end of horizontal pipe 42 is connected with the lateral wall of pump case 1 and the other end is connected with vertical pipe 41, sets up down with the help of the mouth of pipe 411 of vertical pipe 41, and mouth of pipe 411 can be infinitely close the bottom surface of water tank to can be with the water extraction of low water level, the water economy resource.
The above disclosure is only a preferred embodiment of the present invention, and the scope of the claims of the present invention should not be limited thereby, and all the equivalent changes made in the claims of the present invention are intended to be covered by the present invention.
