Specific embodiment

To keep the contents of the present invention more clear and easy to understand, below in conjunction with Figure of description, the contents of the present invention are done into one Walk explanation.Certainly the invention is not limited to the specific embodiment, and general replacement well known to those skilled in the art is also contained Lid is within the scope of the present invention.

Secondly, the present invention has carried out detailed statement using schematic diagram, in detail that example of the present invention, for the ease of saying Bright, schematic diagram is not partially enlarged in proportion to the general scale, should not be to this as restriction of the invention.

Fig. 1 is the structural schematic diagram of liquid storage device provided by one embodiment of the invention, as shown in Figure 1, the present invention provides one Kind liquid storage device air intake duct, air intake duct 1 pass through liquid storage device shell 2 and are passed through in liquid storage device, and the air intake duct is L-shaped, including inlet end 3, transitioning end 4 and connecting pin 5, the inlet end 3 are a straight tubes being located in the liquid storage device shell 2, and the transitioning end 4 is one Positioned at curve bend shell 2 outside and be connected with inlet end 3, the connecting pin 5 passes through the transitioning end 4 and the inlet end 3 connections.

Wherein the inlet end 3 is located in liquid storage device shell, is air intake duct inner tube, material can be iron, copper or stainless Steel etc., preferably stainless steel；The transitioning end 4 and the connecting pin 5 are located at liquid storage device hull outside, are air intake duct outer tube, Material is iron, copper or stainless steel etc., preferably copper.

The air intake duct 1 is integrated, i.e., the described inlet end 3, the transitioning end 4 and the connecting pin 5 are whole one Root canal body, such as can be integrally formed by water swelling method.

The air intake duct 1 or separable assembled structure, i.e., the described inlet end 3, the transitioning end 4 and the connecting pin 5 can be independent tube body, using the connection type of soldering be attached with it is fixed, can also be two-by-two after integrated molding with the The connection of three freestanding bodies.Such as transitioning end 4 and connecting pin 5 are integrally formed and constitute air suction outer tube, in the air suction outer tube and air-breathing By being welded and fixed after the docking of pipe (inlet end 3) nozzle or socket.Or the inlet end 3 is integrally formed with the transitioning end 2, Then by being welded and fixed after docking or be socketed with 5 nozzle of connecting pin.Or the inlet end 3, the transitioning end 4 and institute It states connecting pin 5 and is respectively independent tube body, be attached and fix using the connection type of soldering.

Some researches show that different liquid storage device air intake duct pipe ranges has larger impact to compressor air suction amount.Different air intake ducts Pipe range have a larger impact to the pulsation of air-breathing overpressure, the air intake duct of appropriate length, internal air column can produce resonance and increase Phenomenon is pressed, the air inflow for the compressor being connected with liquid storage device is improved, the volumetric efficiency and refrigerating capacity of compressor can be improved.So And in order to reduce gas-flow resistance, liquid storage device air intake duct as far as possible accomplishes diameter of inner pipe most in the case where meeting fit dimension Greatly, therefore the length of liquid storage device air intake duct and the ratio of internal diameter how are controlled, the performance of liquid storage device is had a major impact, is related to The volumetric efficiency and refrigerating capacity of compressor.
