Description

Technical Field

[0001] This utility model relates to the field of drainage pump technology, specifically to a high-efficiency, quiet drainage pump system that uses a photoelectric sensor switch and is driven by a brushless motor. Background Technology

[0002] Existing drainage pumps generally suffer from problems such as high noise levels, short lifespan, and safety hazards during operation. Traditional drainage pumps typically use microswitches and shaded-pole motors driven by (115V / 230V) AC. Shaded-pole motors are quite noisy during operation, while microswitches rely on the elasticity of metal springs. With repeated switching, the elasticity of the metal springs gradually weakens, leading to a significant reduction in lifespan. Furthermore, each switching contact generates an electric arc, further increasing safety risks.

[0003] Traditional drainage pumps operate by directly controlling a high-voltage (115V / 230V) shaded-pole motor via a microswitch. The motor's start and stop are controlled based on changes in the water level in the tank, thus achieving water level detection and pumping functions. However, due to frequent water level changes, the microswitch needs to operate repeatedly. After long-term compression and stretching, the metal spring gradually loses its elasticity, leading to a shortened switch lifespan. Furthermore, the electric arc generated at the moment of switch contact not only affects the switch's reliability but also poses a significant safety hazard.

[0004] In summary, the design of traditional drainage pumps has obvious defects in terms of high-voltage drive, frequent switching operation, and metal spring life, and urgently needs to be improved to enhance the reliability, safety and service life of the products.

[0005] To address this, a high-efficiency, silent drainage pump system based on photoelectric sensor switches and a brushless motor drive is proposed. Utility Model Content

Figures 1-7 As shown, it includes an outer shell 1, a top cover 2 fixedly installed on the top of the outer shell 1, and a protective cover 3 fixedly installed on the upper part of the top cover 2.

[0034] The upper cover 2 has a water pump impeller housing 9 fixedly installed at its bottom, extending into the outer shell 1. A brushless motor 15 is fixedly installed at the upper part of the upper cover 2 and inside the protective cover 3. A water pump impeller 17 is rotatably installed inside the water pump impeller housing 9. The output shaft of the brushless motor 15 extends into the water pump impeller housing 9 and is fixedly connected to the water pump impeller 17. The water pump impeller housing 9 has a water inlet hole that communicates with the inside of the outer shell 1, and a water outlet connector 7 is installed in the water outlet hole of the water pump impeller housing 9. The upper cover 2 has several water inlets 6 that communicate with the inside of the outer shell 1. A photoelectric sensor switch 10 extending into the outer shell 1 is fixedly installed at the bottom of the upper cover 2. A power adapter 12 is fixedly installed inside the protective cover 3. The power adapter 12 is connected in series with the brushless motor 15, and the photoelectric sensor switch 10 is connected in series between the power adapter 12 and the brushless motor 15.

[0035] The photoelectric sensor switch 10 configured according to the above scheme is used to sense the water level inside the housing 1. When the water level inside the housing 1 reaches the set value, the photoelectric sensor switch 10 is turned on. At this time, a circuit is formed between the power adapter 12 and the brushless motor 15. The brushless motor 15 automatically starts and drives the water pump impeller 17 to rotate and discharge the water inside the housing 1, thus achieving the purpose of automatic drainage. The brushless motor 15 has high working efficiency and good noise reduction effect when working. The photoelectric sensor switch 10 has the advantages of anti-interference, stability, long life, fast response speed and high safety performance.

It features high sensitivity and fast response (suitable for dynamic water level detection).

[0037] To facilitate the disassembly and assembly of the water outlet connector 7, a slot 14 is provided on the protective cover 3. At the same time, a locking block 13 is fixedly installed on the outside of the water outlet connector 7. The locking block 13 can be inserted through the slot 14 and locked into the bottom of the protective cover 3 by rotation. When the locking block 13 is locked into the bottom of the protective cover 3, the water outlet connector 7 is tightly connected to the water outlet hole of the water pump impeller housing 9.

[0038] For easy power connection, the power cord 8 on the power adapter 12 extends to the outside of the protective cover 3.

[0039] Among them, the power adapter 12 can be a step-down transformer that converts high voltage to low voltage (24V) (115V / 230V).

[0040] To prevent larger impurities from entering the housing 1 and causing blockage of the water pump impeller housing 9, filter cylinders 16 are fixedly installed at the bottom of the inlet 6. The filter cylinders 16 are located inside the housing 1. To further prevent larger impurities from entering the housing 1, filter railings 11 are also fixedly installed inside the housing 1 at the positions corresponding to the outer periphery of the filter cylinders 16.

[0041] To display the working status, a status display panel 4 is fixedly installed on the upper part of the protective cover 3. Status indicator lights are installed on the status display panel 4 and are connected in series between the power adapter 12 and the photoelectric sensor switch 10.

[0043] To ensure that the efficient and silent drainage pump system can be quickly and accurately positioned during installation, several positioning grooves 18 are provided on the bottom of the housing 1.

[0044] In summary, the high-efficiency, silent drainage pump system using a photoelectric sensor switch and a brushless motor drive provided in this embodiment has the following advantages:

[0045] The photoelectric sensor switch 10 is used to sense the water level inside the housing 1. When the water level inside the housing 1 reaches the set value, the photoelectric sensor switch 10 is turned on. At this time, a circuit is formed between the power adapter 12 and the brushless motor 15. The brushless motor 15 automatically starts and drives the water pump impeller 17 to rotate and discharge the water inside the housing 1, thus achieving the purpose of automatic drainage. The brushless motor 15 has high working efficiency and good noise reduction. The photoelectric sensor switch 10 has the advantages of anti-interference, stability, long life, fast response speed and high safety performance.

[0046] When in use, connect the end of the power cord 8 away from the power adapter 12 to the mains power or other power source. When water enters the housing 1 through the inlet 6 and reaches the set liquid level, the photoelectric sensor switch 10 is turned on. At this time, a circuit is formed between the power adapter 12 and the brushless motor 15. The brushless motor 15 automatically drives the water pump impeller 17 to rotate and discharge the water in the housing 1, thus achieving the purpose of automatic drainage.
