Abstract
A water pump for use in steam cleaning devices includes a plunger pump with check valve and a transmission assembly. The plunger pump with check valve includes a water inlet and a water outlet. The transmission assembly includes a gear transmission system, an eccentric wheel, and a plunger pump push block. The output shaft of the gear transmission system drives rotation of an eccentric wheel. The push block has a reset structure which makes one end of the push block engage the eccentric wheel. The other end of the push block engages a plunger of the plunger pump with check valve. The pump has a simple structural arrangement, requires no additional power source, and provides consistent water flow at a low manufacturing cost.
Description
- This application claims the benefit of pending Chinese Patent Application No. 201220197438.X filed May 4, 2012, the entire teachings of which are incorporated herein by reference. This application is additionally a Continuation-in-Part of pending U.S. patent application Ser. No. 13/742,910, filed Jan. 16, 2013, the entire teachings of which are incorporated herein by reference.
- The present invention is related to water pumps used in steam cleaning devices, and more specifically to a mechanically driven plunger pump.
- Water pumps are machines which transfer fluid or increase fluid pressure. With advances in development of water pump technology, the range of the water pump applications is widening.
- Water pumps are indispensable components of many steam cleaning devices. Prior art steam cleaning devices generally employ either mechanical or electromagnetic water pumps. For instance, an electromagnetic water pump is taught in Chinese Patent No CN100420856C, which drives a rotator by electromagnetic induction so that the rotator rotates impellors to generate increased water pressure. However, electromagnetic water pumps are expensive to manufacture and require special connectors according to each application. Alternatively, while mechanical water pumps of the prior art are less expensive to manufacture, they suffer from inconsistent water flow, and can be inconvenient to use. Therefore, there exists a need for improvements in water pumps for use in steam cleaning devices.
- The present invention provides a low-cost water pump capable of consistent and reliable water flow.
- To realize this, an exemplary water pump is depicted and described herein which consists of a plunger pump with check valve and a transmission assembly, the check valve having a water inlet and a water outlet. The transmission assembly consists of a gear system, an eccentric wheel, and a plunger pump push block. An output shaft of the gear system drives rotation of the eccentric wheel. The push block includes a reset structure which makes one end of the push block engage the eccentric wheel. The other end of the push block is secured to the plunger with check valve.
- The plunger pump with check valve includes the water inlet and the water outlet, a first check valve port, a second check valve port, a first check valve spring, a second check valve spring, a plunger pump unit, a first seal ring, a second seal ring on the plunger, and a friction plate. The first check valve port and the spring include the water inlet unit while the second check valve port and the second check valve spring include the water outlet unit. The water inlet and water outlet are connected to the plunger pump unit separately. The first seal ring is disposed at the front end of the plunger. The friction plate passes through the second seal ring and is disposed at the tail end of the plunger. The gear system is energized by the power source of the steam cleaning device.
- In comparison to the prior art, this new pump possesses at least the following advantages:
- 1. It employs rotational operation so that, at a low manufacturing cost, it can utilize the same power source as the steam cleaning device.
- 2. It employs a mechanical plunger pump which transfers power from the eccentric wheel and pushes the pump plunger to pump the water through the check valve to the boiler so that the water supply is continuous and consistent.
- 3. The eccentric wheel assembly drives the plunger pump in a simple structural arrangement, to eliminate common failures inherent in electromagnetic pumps, such as fluid flow inconsistencies and failures caused by overheating from blockages or dry operation.
