Technical field
The present invention relates to a kind of pressure-regulating device, relate in particular to a kind of vacuum pressure adjustment that is applied in the unit of sexual massager.
Background technology
At present, increasing human body therapy apparatus need use that vacuum method operates, for example the women is used for curing the powder actuated unit of sexual massager of women's frigidity, but owing to use each user physical qualification of this apparatus different, needed vacuum pressure size also can be different.For reaching best result of use, the vacuum of this therapeutic device should be regulated, and is to regulate effectively, and the pressure after it is regulated also should be stable.There is similar products like to adopt diverse ways controlled pressure value in the market, as Electronic Control that adopts and the hermetically-sealed construction method of using compressed-air actuated product employing precision, though as seen it has reached the purpose of regulating and control vacuum pressure, but need higher manufacturing cost comparatively speaking, because complex structure, its maintenance cost is also high, is difficult for being accepted by popular.Vacuum pressure is regulated and controlled to some external product employing " gas leakage " mode in addition.The shortcoming of this method is that energy loss is serious, and can not accurately reach controlled pressure stably, influences result of use.
Summary of the invention
The technical problem that the present invention solves is the defective that overcomes prior art, a kind of easy control is provided and regulates the vacuum pressure adjustment unit of sexual massager of final vacuum pressure stability.
The present invention is for addressing the above problem, and the technical scheme that is adopted is as follows: vacuum pressure adjustment unit of sexual massager comprises pulling sleeve, spring, regulating sleeve, main casing and elastic cup; Establish screw thread in the regulating sleeve, regulating sleeve passes behind the threaded hole of spring and the described pulling sleeve and stretches out the pulling sleeve, and the spring roof pressure is between pulling sleeve upper surface and regulating sleeve bottom; Be provided with the external thread rod that is connected dividing wall center in the main casing in the main casing, this external thread rod stretches in the regulating sleeve and is spirally connected with regulating sleeve; Elastic cup places the cylindrical cavity of the intravital bottom of main casing, and the elastic cup center is provided with the center short column, and the center short column is provided with the passage of break-through up and down, and dividing wall and elastic cup center short column snapping are passed in described pulling sleeve lower surface; Dividing wall lower surface formation sealing surface in the main casing is pasted on the top, upper surface of center short column; The main casing bottom is provided with the pipe joint that is used for connectivity masseur pressure chamber, and elastic cup periphery sealing paste is connected to the main casing inwall, forms sealed chamber between the passage of pipe joint and elastic cup center short column.
The present invention is connected with elastic cup is more firm in order to make the pulling sleeve, between pulling sleeve and elastic cup the leather cup adapter is set; Along the circumferential direction be provided with at least two cantilever hooks in the telescopic lower surface of pulling, on the intravital dividing wall of main casing, be provided with groove with respect to the cantilever hooks position; The leather cup adapter places the cylindrical cavity of the intravital bottom of main casing, in the middle of the leather cup adapter is through hole, its upper surface along the circumferential direction is provided with and the cantilever hooks that spurs the corresponding coupling of sleeve upper cantilever hook, and the cantilever hooks on the described pulling sleeve is passed groove on the dividing wall and the cantilever hooks snapping on the leather cup adapter; The periphery, top of elastic cup center short column is provided with scrobicular ring, the center short column of elastic cup is pressed in the through hole of elastic cup adapter through the lower surface of leather cup adapter, dividing wall lower surface formation sealing surface in the main casing is pasted in the rim of through hole interlocking on the scrobicular ring of the periphery, top of center short column and the elastic cup adapter, the top, upper surface of center short column.
The present invention is for the ease of assembling and making, in the main casing bottom end cap is set, in the end cap is circular chamber, the pipe joint that is used for connectivity masseur pressure chamber is located at end cap one side, end cap and main casing bottom are sealedly and fixedly connected, and form sealed chamber between the passage of pipe joint and elastic cup center short column.
The present invention is to be provided with annular boss on the cylindrical chamber locular wall in order to make being tightly connected more of main casing, end cap and elastic cup in the intravital bottom of main casing; Be provided with on the circular cavity locular wall in end cap one with main casing in annular boss symmetry annular boss, end cap is clamped elastic cup edge sealing and fixing through two symmetrical annular boss bottom main casing.
The present invention seals clamping connection more for the edge that makes on main casing, the end cap two symmetrical annular boss and elastic cup, and elastic cup is provided with " T " font annular outer rim, is provided with and the annular outer rim corresponding groove at two symmetrical annular boss.
Cantilever hooks on the pulling sleeve of the present invention is introversive hook-shaped, and the cantilever hooks on the leather cup adapter be export-oriented hook-shaped, or the cantilever hooks on the pulling sleeve be export-oriented hook-shaped, and the cantilever hooks on the leather cup adapter is that introversion is hook-shaped, mutual snapping.
When regulating sleeve rotates when mobile, will spur adapter and force the center short column of elastic cup to press to sealing surfaces by the compression spring, therefore set up sealing for producing vacuum.When having vacuum pressure in the sealed chamber, will produce a power of attempting the center short column of elastic cup is pulled away from sealing surface, this is to order about the center short column to leave sealing surface.The pneumatics power of taking seriously arrives when to a certain degree making suction greater than spring pressure, gas leak phenomenon will take place on sealing surface make vacuum pressure get back to equal spring pressure.Therefore vacuum pressure can remain on the spring setup pressure value.So, cause the decrement of setting spring just to set the interior force value of vacuum chamber thereby set regulating sleeve.
The present invention adopts metal compression spring controlled pressure overflow structure, utilize regulating spring pressure to obtain different force value, moreover, being used for pressure controlled spring places outside the vacuum chamber, therefore reduced the required precision that the product hermetically-sealed construction is made, thereby improved the reliability of product operation, also reduced paying of production cost and labour force.While overall structure advantages of simple, exquisitenessization has realized the low-cost and high-quality operation, has further also guaranteed to regulate the stable of final vacuum pressure.
