Description

Technical Field

[0001] The utility model relates to the technical field of blade centrifugal water pumps, in particular to a split heat dissipation type intelligent multi-purpose pump. Background Art

[0002] In order to be compact, the existing water pump makes the pump casing completely fit the motor. Since the motor is wrapped on all sides, it is not conducive to the heat dissipation of the motor. At the same time, since the compact casing is close to the motor, the support circumference at the lower end of the pump casing cannot be made too large. When the pump is working, there is a risk of tipping over due to the small diameter of the support circumference. In addition, the existing water pump cannot automatically pump water according to the water level. When the water level is too low, the water supply is automatically stopped and manual operation is required to start and stop it, which is inconvenient. Utility Model Content

[0017] The technical solutions in the embodiments of the present utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present utility model.

[0018] See also Figure 1-3 , the utility model embodiment includes:

[0019] A split heat dissipation type intelligent multi-purpose pump, the structure of which includes: a pump casing 1, a motor 2, a pump cover sealing ring 3, an O-ring 4, a pump cover 5, an impeller 6, a volute 7, a base 8, and a water level sensor 9.

[0020] The pump casing is provided with a mounting cavity 10 for mounting the motor, so that the upper housing of the motor is limitedly mounted through the mounting cavity, the pump cover is connected to the lower part of the pump casing, and the pump cover is provided with a clamping protrusion 11, which is sealingly connected to the bottom housing of the motor to clamp and fix the motor in the pump casing and the pump cover, and a heat dissipation gap is provided between the lower housing of the motor and the pump casing and / or the pump cover, so that the motor does not contact the pump casing in its entirety but directly contacts the air in the heat dissipation gap, which is beneficial to heat dissipation.

[0021] Further preferably, the pump casing and the pump cover are split structures.

[0022] Further preferably, the clamping protrusion is sealed and connected to the housing of the motor via a pump cover sealing ring.

[0023] Further preferably, the pump cover is sealed to the output inner hole of the pump housing via an O-ring to achieve sealing of the water channel.

[0024] Further preferably, the diameter of the support seat at the lower part of the pump housing is larger than the diameter of the installation cavity.

[0025] The motor shaft of the motor passes through the pump cover and is connected to the impeller. The volute and the base for filtering impurities are sequentially covered on the pump casing and / or the pump cover outside the impeller from the inside to the outside. The water level sensor is arranged in the pump casing to detect the current water level.

[0026] Further preferably, the water level sensor pump housing has a high water level probe 92 and a low water level probe 91 .

[0027] When the pump is working, if the high water level probe detects the water level, the pump will automatically start to pump water. If the water level drops to a level that is detected by the low water level probe, the pump will automatically stop. This is very smart and convenient and does not require manual control all the time.

[0028] The utility model has the following beneficial effects:

[0029] 1. The lower part of the motor casing does not touch the pump casing, but directly contacts the air. There is a large space between the motor casing and the pump casing, which is conducive to heat dissipation. At the same time, since the pump casing does not touch the motor tightly, the lower end diameter can be made larger, and the pump is relatively stable on the ground and will not tip over.

[0030] 2. Split pump casing: when the requirements for the impeller and volute change, there is no need to redo the entire pump casing. Instead, you only need to adjust the pump cover and impeller volute to match them, which greatly improves the flexibility of the product.

[0031] 3. The water level sensor automatically determines the water level and controls the start and stop of the pump, which is intelligent and convenient.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
