Description

Technical Field

[0002] Currently, water pumps are increasingly widely used, and the power mechanism that drives the impeller to rotate is one of the indispensable mechanisms of the water pump.

[0003] For the water pump structures on the market, most of them directly connect the output end of the power mechanism to the rotating shaft of the impeller. When the water pump needs to operate, the impeller can be driven to rotate by the motor in the power mechanism to achieve the purpose of drainage. However, when faced with large-scale continuous drainage operations, the torque generated by the direct connection between the power mechanism and the rotating shaft on the impeller is relatively small, which affects the smoothness and stability of the drainage process, and ultimately leads to a decrease in the overall work efficiency of the water pump during the drainage process.

[0039] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0040] like Figures 1 to 4 As shown, the utility model is a portable water pump, comprising: a water pump body 1, provided with a water suction pipe 10 and a drainage pipe 11; a mounting seat 2, arranged in the water pump body 1, a receiving chamber 20 is formed in the mounting seat 2, the water suction pipe 10 and the drainage pipe 11 are respectively connected to the two sides of the mounting seat 2 and pass through the water pump body 1, and the water suction pipe 10, the drainage pipe 11 and the receiving chamber 20 are interconnected; an impeller mechanism 3, arranged in the receiving chamber 20, and when the impeller mechanism 3 rotates, it is used to guide external water from the water suction pipe 10 into the receiving chamber 20, and discharged from the drainage pipe 11; a power mechanism 4, connected to the mounting seat 2, a driving end of the power mechanism 4 extends into the mounting seat 2, and is movably engaged with the impeller mechanism 3, so as to increase the torque when the power mechanism 4 drives the impeller mechanism 3 to rotate.

[0041] It is worth noting that the power mechanism 4 used in this solution is the same as the commonly used specifications. The difference is that the water pump has made further improvements to the installation structure of the power mechanism 4 and the impeller mechanism 3. Specifically, Figure 2 As shown, the driving end of the power mechanism 4 is movably engaged with the impeller mechanism 3, that is to say, the two are not coaxially connected, and the gears therebetween are used to increase the torque when the driving motor 40 drives the impeller 31 to rotate, thereby ensuring that during the rotation of the impeller mechanism 3, external water can be smoothly drawn into the water suction pipe 10 and discharged from the water pump body 1 through the drainage pipe 11 through the accommodating chamber 20. The overall structure is simple, which effectively improves the smoothness and stability of the drainage process, and also provides a guarantee for the overall working efficiency of the water pump during the drainage process.

[0042] The impeller mechanism 3 includes: a rotating shaft 30, which is rotatably arranged in the mounting seat 2; an impeller 31, which is connected to the end of the rotating shaft 30 and movably arranged in the accommodating chamber 20, and is used to guide water from the suction pipe 10 to the drainage pipe 11 through the accommodating chamber 20 when the impeller 31 rotates; a driven gear 32, which is arranged at one end of the rotating shaft 30 away from the impeller 31, and the driven gear 32 is movably engaged with the power mechanism 4, so that when the power mechanism 4 is started, it can drive the rotating shaft 30 to rotate through the driven gear 32.

[0043] like Figure 2As shown, when the power mechanism 4 is turned on, the torque applied to the driven gear 32 by the power mechanism 4 can be used to make the driven gear 32 rotate and drive the rotating shaft 30 to rotate synchronously, and finally the impeller 31 at the end of the rotating shaft 30 rotates in the accommodating chamber 20, thereby pumping water from the suction pipe 10 into the accommodating chamber 20, and as the impeller 31 rotates, the water is discharged from the drain pipe 11 to the outside of the water pump body 1.

[0044] The power mechanism 4 includes: a driving motor 40, which is located in the installation cavity and connected to the installation seat 2. The driving motor 40 is provided with an output shaft 41, and the output shaft 41 is not coaxial with the rotating shaft 30; a driving gear, which is provided at the end of the output shaft 41, and the driving gear is movably meshed with the driven gear 32.

[0045] Further, if Figure 2 As shown, unlike the conventional arrangement, the output shaft 41 of the driving motor 40 in this scheme is not coaxially connected to the above-mentioned rotating shaft 30, so that when the driving motor 40 is driven, the driving gear (not shown in the figure) at the end of the output shaft 41 can be used to drive the driven gear 32 to rotate. It should be noted that the driving gear and the driven gear in this scheme are meshed with helical gears, which is beneficial to increase the meshing strength and ensure smooth operation; that is, the structure realizes the rotation of the impeller 31 in the accommodating chamber 20 through a primary transmission, greatly increases the torque when the driving motor 40 drives the impeller 31 to rotate, ensures that the impeller 31 can smoothly and stably realize the drainage function, and also avoids the direct connection of the output shaft 41 of the driving motor 40 to the rotating shaft 30 and damage in large-scale continuous drainage, thereby extending the service life of the water pump.

[0046] A sensor 21 is also provided on the mounting base 2 . The sensor 21 is distributed at one end of the water suction pipe 10 and the drainage pipe 11 close to the accommodating chamber 20 .

[0047] Continue to refer Figure 3 and Figure 4 When the driving motor 40 drives the impeller 31 to rotate for pumping, if no water enters from the pumping pipe 10 or no water is discharged from the drain pipe 11, the sensor 21 can detect whether there is water in the pumping pipe 10 and the drain pipe 11. If it is determined that no water enters the accommodating chamber 20 or no water flows out from the accommodating chamber 20, the signal can be transmitted to the driving motor 40 through the controller to stop the drainage operation. This structure has a good waterless protection effect on the water pump as a whole, effectively preventing the driving motor 40 from driving the impeller 31 to perform empty operation, avoiding damage to components, and extending the service life.

[0048] A plurality of mounting grooves 22 are formed in the mounting seat 2, each of which is provided with a bearing 23. The rotating shaft 30 is movably sleeved with bearings 23 located on both sides of the driven gear 32; a stepped block 410 is formed on the output shaft 41, and the bearing 23 is movably sleeved on the output shaft 41 and pressed against the stepped block 410.

[0049] like Figure 2 As shown, a bearing 23 is correspondingly arranged in each mounting groove 22. The bearing 23 can improve the smoothness of the rotation of the rotating shaft 30 and the output shaft 41, thereby ensuring that the impeller 31 smoothly and stably performs the drainage function when the drive motor 40 is turned on. It is worth noting that the step block 410 on the output shaft 41 can have an axial limiting effect on the bearing 23 on the output shaft 41, thereby ensuring the stability of the installation of the bearing 23.

[0050] The accommodating chamber 20 is arranged in multiple arc sections. The water suction pipe 10 and the drainage pipe 11 are coaxial and tangent to the top of the accommodating chamber 20 . The impeller 31 is eccentrically arranged in the accommodating chamber 20 , and the impeller 31 fits tightly against the inner wall of the accommodating chamber 20 .

[0051] like Figure 3 As shown in FIG. 1 , the center line of the accommodating chamber 20 composed of multiple arc segments and the center line of the rotating shaft 30 of the impeller 31 (i.e., the axis center line of the rotating shaft 30) are not on the same straight line. Furthermore, in this solution, the rotating shaft 30 is eccentrically arranged at a position close to the top of the accommodating chamber 20, so that the impeller 31 is Figure 3 The upper left and upper right parts are located at the ports of the drain pipe 11 and the suction pipe 10 respectively, and the impeller 31 is in a tight fit with the inner wall of the accommodating chamber 20. It should be noted that the blades of the impeller are made of elastic and deformable materials. With the eccentric setting of the impeller, the blades are always in a tight fit with the inner wall of the accommodating chamber, and thus during the rotation of the impeller 31, the external water can be smoothly guided from the suction pipe 10 to the accommodating chamber 20. As the impeller 31 continues to rotate, the water in the accommodating chamber 20 is brought into the drain pipe 11, and the water is discharged to the outside of the pump body 1 by the drain pipe 11. The overall structure is relatively simple, which effectively improves the fluency and stability of the impeller 31 during drainage operations.

[0052] Preferably, the mounting base 2 in this solution is also provided with a temperature sensor (not shown in the figure), which is located between the two sensors 21. When the drive motor 40 drives the impeller 31 to perform drainage operations, the temperature sensor 21 is used to detect the water temperature in the accommodating chamber 20. In this solution, when the temperature of the passing water or the temperature of the mounting base exceeds 60 degrees Celsius, the controller can give a signal to the drive motor 40 to stop operating, thereby protecting the user's safety and preventing the drive motor from being damaged. It should be noted that the working principle of the temperature sensor 21 is mainly based on the hot spot effect, resistance effect, thermistor effect, thermocouple effect, infrared absorption effect and other principles of the material, and converts the temperature signal into an electrical signal.

[0053] The mounting base 2 includes a first shell 24 and a second shell 25 which are detachably connected to each other. The first shell 24 is detachably connected to the water pump body, and the impeller 31, the water suction pipe 10, the drainage pipe 11 and the accommodating chamber 20 are all arranged in the first shell 24, and the driving gear and the driven gear 32 are both arranged in the second shell 25.

[0054] like Figure 4 As shown, the mounting base 2 consists of a first shell 24 and a second shell 25, wherein the impeller 31 is mainly arranged in the first shell 24, and the rotating shaft 30 extends into the second shell 25. It can be seen that during the installation process, the impeller 31 and the rotating shaft 30 are pre-installed in the first shell 24. Since the end of the rotating shaft 30 away from the impeller 31 extends out of the first shell 24 at this time, after the driven gear 32 and the bearing 23 on the rotating shaft 30 are accurately installed and the driving motor 40 is installed on the second shell 25, the second shell 25 can be detachably connected to the first shell 24 by screws, and at the same time, the driving gear and the driven gear 32 are movably engaged to ensure that when the driving motor 40 is started, the impeller 31 can be smoothly driven to rotate through the driven gear 32 to realize the drainage function of the water pump. The overall structure is relatively simple, which provides convenience for workers to install and disassemble, and is also convenient for subsequent maintenance and replacement.

[0055] Preferably, a through groove 12 is formed on the water pump body in this solution. When the user needs to lift and carry the water pump, the user can easily pass his fingers through the through groove 12 and complete the grabbing of the water pump body 1, which greatly provides convenience for the user during use. In addition, this solution also provides an oil seal (not shown in the figure) in the first housing, and a square sealing ring is installed on the outside of the first housing and the second housing where the bearing is installed. The oil seal can effectively prevent the water in the accommodating cavity from leaking out, and the square sealing ring can prevent the bearing from axial displacement, thereby improving the stability of the structure and the life of the motor, and extending the service life.

[0056] Preferably, the water pump body 1 in this solution is also provided with a lighting lamp 5, which can provide lighting effect when used at night, providing convenience for users.

If the specific posture changes, the directional indication will also change accordingly.
