Abstract
The utility model discloses a kind of modified node method of pump motor water bag, comprise water tank, cold/hot dressing film, the first water pump, the second water pump; The outlet of described water tank is connected by the entrance of pipeline with the first water pump, first water delivery side of pump is connected by the entrance of pipeline with cold/hot dressing film, the outlet of cold/hot dressing film is connected by the entrance of pipeline with the second water pump, and the second water delivery side of pump is connected with the entrance of water tank by pipeline.Because this utility model has two water pumps, one is water filling water pump, and one when the water yield of the water pump that draws water is greater than the water injection rate of water filling water pump, just can make cold/hot dressing film be in flat form all the time for drawing water water pump, closely can be fitted in the position that people need treat.
Description
Technical field
This utility model relates to a kind of nursing health equipment, particularly relates to a kind of modified node method of pump motor water bag.
Background technology
Cold compress and hot compress are common physical therapy modalities.Wherein, cold compress is generally used for reducing swelling and alleviating pain etc., and hot compress is generally used for relaxing muscles and tendons to promote blood circulation etc.Under prior art conditions, cold compress is mainly realized by ice bag or cold wet towel, and hot compress rule is mainly realized by hot-water bag or hot towel.Practice shows, the onset time (i.e. low temperature continuous time) of existing cold compress is general shorter, causing the needs when carrying out cold compress frequently to change ice bag or cold wet towel, affecting therapeutic efficiency thus.Similarly, the onset time (i.e. high-temperature duration) of existing hot compress is general shorter, causing the needs when carrying out hot compress frequently to change hot-water bag or hot towel, affecting therapeutic efficiency thus.For this reason, have devised by dealer the cold compress water bag that water tank, cold/hot dressing film, water pump etc. form, there is the problem of cold/hot dressing film tympanites in this existing water bag, and the position that cold/hot dressing film cannot be made closely to be fitted in people need treat, as face.
Summary of the invention
The purpose of this utility model is that providing a kind of can be fitted in the modified node method that people needs the pump motor water bag of therapentic part closely.
For achieving the above object, technical solution of the present utility model is:
This utility model is a kind of modified node method of pump motor water bag, comprises water tank, cold/hot dressing film, the first water pump, the second water pump; The outlet of described water tank is connected by the entrance of pipeline with the first water pump, first water delivery side of pump is connected by the entrance of pipeline with cold/hot dressing film, the outlet of cold/hot dressing film is connected by the entrance of pipeline with the second water pump, and the second water delivery side of pump is connected with the entrance of water tank by pipeline.
The water injection rate of described the first water pump as water filling water pump is less than the pump-out of the second water pump as the water pump that draws water.
The pipe diameter of described water outlet of water tank is greater than the pipe diameter of water tank inlet.
After adopting such scheme, because this utility model has two water pumps, one is water filling water pump, one is the water pump that draws water, when the water yield of the water pump that draws water is greater than the water injection rate of water filling water pump, cold/hot dressing film just can be made to be in flat form all the time, closely can be fitted in the position that people need treat.
Below in conjunction with the drawings and specific embodiments, this utility model is further described.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
As shown in Figure 1, this utility model is a kind of modified node method of pump motor water bag, comprises water tank 1, cold/hot dressing film 2, first water pump 3, second water pump 4.
The outlet of described water tank 1 is connected by the entrance of pipeline with the first water pump 3 as water filling water pump, the outlet of the first water pump 3 is connected by the entrance of pipeline with cold/hot dressing film 2, the outlet of cold/hot dressing film 2 is connected by the entrance of pipeline with the second water pump 4 as the water pump that draws water, the outlet of the second water pump 4 is connected by the entrance of pipeline with water tank 1, forms a circulating water flow passage.
Operation principle of the present utility model:
During use, first water pump 3 and the second water pump 4 are opened simultaneously, water injection rate as the first water pump 3 of water filling water pump is less than the pump-out of the second water pump 4 as the water pump that draws water, make the water yield entered in cold/hot dressing film 2 be less than the water yield of extracting cold/hot dressing film 2 out all the time, make cold/hot dressing film 2 be in flat form all the time.
It should be noted that: the mode that the realization water yield entered in cold/hot dressing film 2 is less than the water yield of extracting cold/hot dressing film 2 out all the time can also be following two kinds:
1, when the pipe diameter of water tank 1 outlet is greater than the pipe diameter of water tank 1 water inlet, also can realize circling water flow rate when the first water pump 3 is the same with the water injection rate of the second water pump 4 and be greater than discharge.2
2, when the first water pump 3 is the same with the water injection rate of the second water pump 4, by software control first water pump 3 discontinuous operation, also can reach circling water flow rate and be greater than discharge.
Emphasis of the present utility model is just: many water pumps, and backwater amount is greater than inflow simultaneously.
The above, be only this utility model preferred embodiment, therefore can not limit with this scope that this utility model implements, the equivalence namely done according to this utility model claim and description change with modify, all should still belong in scope that this utility model patent contains.
