Detailed Description
The utility model provides a miniature water pump, for making the utility model discloses a purpose, technical scheme and effect are clearer, make clear and definite, and it is right that the following refers to the attached drawing and the embodiment of lifting the utility model discloses further detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.
Referring to fig. 1 to 5, the present invention provides a micro water pump.
The miniature water pump comprises a shell 1 and an adjusting switch 4, wherein an impeller cavity 2 is arranged at the front end of the shell, and a water outlet pipe 5 is arranged on the shell. A water outlet 201 (shown in fig. 4) is arranged on the impeller cavity 2, and the water outlet pipe 5 corresponds to the water outlet 201; an impeller 3 is arranged in the impeller cavity, and a motor (not observed in the figure) for driving the impeller to rotate is arranged in the shell; the regulating switch 4 comprises a cylinder 41, an end plate 42 and a handle 43 connected with the end plate, wherein the middle part of the end plate is provided with a water inlet, the cylinder is provided with an opening in the circumferential direction, the cylinder is matched with the impeller cavity and can rotate relative to the impeller cavity, namely the outer diameter of the impeller cavity is equal to the inner diameter of the cylinder. The regulating switch is matched with the impeller cavity to form a complete volute, and water can be sucked from the water inlet and then discharged from the water outlet pipe after the impeller rotates. In practical application, a circuit board (not shown in the figure) is further arranged in the shell, and the shell is arranged in a sealing mode, so that normal operation of components such as a motor in the shell is guaranteed.
Further, the housing is connected with a front cover 6, the front cover is provided with a water inlet 601, and the front cover is internally provided with an activated carbon filter sponge 69 (shown in fig. 2), so that water can be filtered to achieve the purpose of cleaning.
Preferably, the bezel is provided with an arcuate aperture 602, and the end of the handle 43 of the adjustment switch extends through the arcuate aperture 602, the arrangement being such that rotation of the handle of the adjustment switch does not interfere with the bezel.
Preferably, the outlet pipe 4 is located above the housing.
Further, a detection probe 81 (as shown in fig. 2) is disposed on one side of the housing, and when a water-free state is detected, the motor stops rotating, so as to prevent the micro-water pump from being dried, and prolong the service life.
Further, the LED lamp 82 is arranged on the shell, and the miniature water pump can be observed conveniently when the lighting is poor (such as at night) by the arrangement of the LED lamp.
Further, the impeller comprises permanent magnet steel (not shown in the figure). When the device is actually used, the alternating frequency and the wave form of the current wave input to the stator coil of the brushless motor are changed, a magnetic field rotating around the geometric axis of the motor is formed around the winding coil, and the magnetic field drives the permanent magnet steel on the rotor to rotate, so that the impeller is driven to rotate.
Preferably, the bottom of the shell is provided with a plurality of vacuum suction cups 11, so that the miniature water pump can be fixed or moved quickly; in addition, during actual operation, the vacuum chuck can play a damping role, and the water pump is prevented from generating noise.
Further, a WiFi module (not shown in the figure) is arranged in the shell and connected with a circuit board of the micro-water pump. Through setting up the wiFi module, can further expand miniature water pump's function. During the in-service use, the cell-phone passes through wiFi with miniature pump to be connected, can control the flow of water pump, the time of going out water, the control of water pump lamp, the warning of water pump lack of water, the control of water pump response water quality is reminded, the water pump takes night vision and video function etc.. It should be noted that, the utility model discloses what protect is miniature pump itself, rather than requesting protection cell-phone APP.
When the miniature water pump is actually used, the miniature water pump is placed in a water tank (not shown in the figure), a water pipe can be further connected onto a water outlet pipe according to actual requirements, a motor of the miniature water pump is connected with an external power supply, and the motor can be driven to rotate by the working power supply AC12V or DC5V, so that water in the water tank is pumped to a required place. When the flow needs to be adjusted, only the handle of the adjusting switch needs to be rotated, and when the opening on the cylinder of the adjusting switch is aligned with the water outlet on the impeller cavity, the flow reaches the maximum; and when the cylinder of the regulating switch gradually blocks the water outlet on the impeller cavity, the flow is gradually reduced.
Through the analysis, compared with the prior art, the flow can be conveniently adjusted by arranging the impeller cavity and the adjusting switch. Because the regulating switch simultaneously plays a part of the volute, the miniature water pump is ensured to have simple structure and small occupied space. When in actual use, the flow regulation is convenient and the use is easy. Further, through the time setting protecgulum and active carbon filter sponge, can play the effect of purified water, and keep water pump simple structure's advantage on the whole.
It is understood that equivalent substitutions or changes can be made by those skilled in the art according to the technical solution of the present invention and the inventive concept thereof, and all such changes or substitutions shall fall within the scope of the present invention.
