Description
Technical field
The utility model relates to shower nozzle, has related in particular to a kind of self-priming portable shower nozzle.
Background technology
At present, family's shower does not have any difficulty in the city, no matter utilizes any modes such as combustion gas, electric energy or solar energy, can easily carry out Water-heating shower.But in special areas such as high and universities, consider safety factor, generally do not have the hot-water heating system in the dormitory, generally in the toilet, running water shower water pipe can be installed.Such shower condition performs practically no function on reality is used in fact, unless because extremely hot summer generally can not directly shower under cold water in south.Press for the low-income group of social concerns in addition at some, especially for the peasant of vast living standard than the poor rural area and the manual labour of going down town, their physical condition causes them to be unwilling or can't buy the water heater that generally uses in the city, even also be down a basin hot water with hot towel wiping health in the winter of cold, also unusual wasted heat of inconvenience so very.More existing on the market portable shower baths consider to save cost, the use plastic material is one-body molded, the long-term use is out of shape under the hot water environment easily, regulate the water temperature deterioration in accuracy, and very easily cause shower nozzle to stop up in the hard partially area of northern water quality, final because be difficult to service life in large-scale popularization on the market.
Summary of the invention
The utility model is simple in structure at shower nozzle in the prior art, with shortcomings such as hot water mixed effect differences, provide a kind of providing to utilize principle of hydrodynamics to become warm water to spray with cold water mix the hot water suction from shower nozzle, durable in use, install and self-priming portable shower nozzle easy to carry.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
Self-priming portable shower nozzle, comprise and being responsible for and shower nozzle, the side that described person in charge two ends were provided with and are responsible for the upper end cavity, were responsible for the lower end cavity and the person in charge is provided with the side pipe cavity, be responsible between upper end cavity and the side pipe cavity and be communicated with, be responsible between lower end cavity and the side pipe cavity by the connection of holing in the middle part of the person in charge down by last persons in charge middle part boring.Water pipe inner cold water inflow pipe upper end cavity is being responsible for upper end cavity and middle part boring taper hole place because the feed pipe flow is constant, and cross-sectional area reduces rapidly, and flow velocity u increases, and causes pressure P to descend, and has just produced negative pressure at the side pipe place.Under the effect of external atmospheric pressure, hot water is pressed into mixing chamber and cold water mix from side pipe, and the shower water that formation temperature is suitable drenches through shower nozzle from being responsible for the lower end cavity.
As preferably, described person in charge upper end cavity is connected with water pipe, and person in charge lower end cavity is connected with shower nozzle, connects side pipe on the side pipe cavity, and side pipe is connected with hot-water line.As preferably, the middle part boring of described side pipe is with to be responsible for the side opening bore consistent, and connects perforation place internal cavities formation mixing chamber with being responsible for middle part boring.
As preferably, described side pipe is provided with external screw thread with being responsible for link, and the other end is provided with the slip-off preventing screw thread, and the middle part is the hex nut shape.The slip-off preventing screw thread is set on the side pipe, therefore makes hot-water line better be connected, avoided leaking with the person in charge.As preferably, body adopts the aluminium alloy cutting processing, can be for a long time uses in that hot water environment (more than 90 ℃) is normal, and not fragile, the convenient installation solved the shower demand of specific group conscientiously.As preferably, be responsible in the cavity of upper end and be provided with internal thread, with between the water pipe by being threaded; Be responsible for the lower end cavity and be outside equipped with external screw thread, with between the shower nozzle by being threaded; Be provided with internal thread in the side pipe cavity, with between the side pipe by being threaded.
As preferably, be provided with internal thread in the described shower nozzle, also be provided with apopore on the shower nozzle.The utility model be suitable for water tap apart from ground greater than 1.5 meters occasion.The temperature of the warm water that sprays relies on the running water switch size to regulate, and promptly the big more coolant-temperature gage that then sprays out opened of running water valve is high more.
The utility model hydrodynamics design principle:
The conservation of energy is natural objective law, and working fluid is also observed law of conservation of energy.This rule is to express with the mathematical form of Bernoulli equation.
1) Bernoulli equation of the small a fluid stream of ideal liquid
For the convenience of research, generally liquid is handled as the ideal liquid that does not have viscous friction.
P/r is the pressure energy that Unit Weight liquid is had in the formula, is called than pressure energy, also is called pressure head.Z is the potential energy that Unit Weight liquid is had, and is called specific potential energy, also is called level head.U2/2g is the kinetic energy that Unit Weight liquid is had, and is called than kinetic energy, also is called velocity head, and their dimension all is a length.
Liquid stream energy equation concerns transition diagram, can do following understanding to Bernoulli equation:
1. bernoulli's equation is an energy equation, and it shows the Energy conservation law of each corresponding through-flow section part circulating liquid in the space.
2. the Bernoulli equation of ideal liquid only is applicable to that the ideal liquid under the gravity effect makes the situation of permanent activity.
3. all corresponding definite bernoulli's equation of any small a fluid stream, promptly for different small a fluid streams, their constant value difference.
The physical significance of Bernoulli equation is: make permanent mobile ideal liquid has three kinds of formation on any one through-flow section energy in closed conduit, i.e. pressure energy, potential energy and kinetic energy.The sum total of three kinds of energy is constant constants, and can change mutually between three kinds of energy, promptly on different through-flow sections, can be different with a kind of value of energy, but the total energy value on each section all is identical.
2) Bernoulli equation of the small a fluid stream of actual liquid
Because liquid exists viscosity, its viscous force and is expressed as resistance to liquid flow in action, flowing of actual liquid will overcome these resistances, is expressed as the consumption and the loss of mechanical energy, therefore, when liquid flow, the gross energy of liquid stream or total specific energy are constantly reducing.
3) Bernoulli equation of the total stream of actual liquid
The applicable elements of Bernoulli equation is:
1. the incompressible liquid of steady flow, promptly density is constant.
2. the suffered mass force of liquid has only gravity, ignores The Effect of Inertia Force.
3. selected two passage sections must be gradually varied flow (be that streamline is bordering on parallel lines, effective cross-section is bordering on the plane) in the flow field of same continuous-flow, and do not consider the flow condition between two sections.
The utility model is owing to adopted above technical scheme, have significant technique effect: the utility model is according to principle of negative pressure, without any need for power, directly be tightened on the running water pipe, by flowing through fast of running water, the hot water in the hot water tank (preferably more than 90 ℃) drunk up and mix the cold water of running water and spray and get off to carry out WBS, it is comfortable to have a shower, easy to use, energy-saving safety.
