Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
The pressure-adjustable booster valve comprises a booster valve body 1, wherein the booster valve body 1 is formed by connecting a valve cap 2 with a valve core 3, the joint of the valve cap 2 and the valve core 3 is sealed, a chamber 4 communicated with the valve core 3 is arranged between the valve core 2 and the valve cap 2, the chamber 4 is communicated with an overflow port 21 on the valve cap 2, the pressure-adjustable booster valve further comprises a flow-limiting plug 5, the flow-limiting plug 5 is inserted into a sleeve 6, an overflow gap 61 is arranged between the flow-limiting plug 5 and the inner wall of the sleeve 6, the sleeve 6 is arranged in the chamber 4 of the valve cap 2, the sleeve 6 is communicated with the chamber 4 of the valve core 3, a plug 51 is arranged on the flow-limiting plug 5, the plug 51 is connected onto the inner wall of the chamber 4 of the valve cap 2 through a spring 52, and the plug 51 is tightly covered on the outer wall of the sleeve 6 through the spring 52.
As the preferred embodiment, the valve core 3 is sleeved and fixed with the adjusting block 31, the sleeve 6 is fixed at the port of the adjusting block 31, the adjusting block 31 is inserted into the valve cap 2, and the adjusting block 31 is fixed with the valve cap 2 by screw threads, so that the elastic pressure of the spring 52 on the adjusting plug 51, namely the pressing force of the adjusting plug 51, can be driven by screwing in or screwing out the adjusting block 31 on the valve cap 2, thereby adjusting the water temperature and the water pressure when coffee is extracted in the kettle.
As a further improvement, the overflow ports 21 are annularly distributed on the outer side of the valve cap 2, the overflow ports 21 are obliquely arranged, and at least one overflow port 21 is annularly distributed, so that the coffee liquid can be conveniently discharged.
As a further improvement, the valve core 3 is made of elastic material and is formed by penetrating from outside to inside by a wide narrowing and tapered gradual changing rectangle.
The pressure-adjustable booster valve is convenient for guiding out the extracted coffee liquid when the booster valve is used for extracting coffee through a cavity 4 communicated between the valve cap 2 and the valve core 3 and an overflow port 21 on the valve cap 2.
When the coffee maker is used, the traditional silica gel plug can be inserted into the through notch, then the traditional silica gel plug is plugged into the cavity 4 on the valve core 3, and then the traditional silica gel plug is fixed at the liquid outlet end of the mocha kettle, so that the coffee maker can be used for pressurizing during coffee extraction.
When coffee is extracted, the mocha kettle is heated and warmed, so that steam pressure is continuously generated by an internal source of the kettle, the pressure is larger than closing force (namely shrinkage force) of an incision of an elastic material of the valve core 3, and water pressure is also larger than pressing force of the spring 52, then an overflow channel of the valve core 3 made of the elastic material can be continuously opened, and then the plug 51 is jacked up, coffee liquid flows through the chamber 4, enters the sleeve through the valve core 3 under preliminary compression and passes through a gap between the current limiting plug 5 and the sleeve 6, circulation is realized, meanwhile, under the action of the pressure, namely the heating in the mocha kettle, the generated pressure can repeatedly jack up the plug 51 of the current limiting plug 5 upwards after the pressure in the kettle is increased to a certain degree, and the plug 51 can be quickly reset under the action of the spring 52 after jack-up, and at the moment, the coffee liquid overflows and is led out from the overflow port 21. Specifically, when the pressure in the mocha kettle is increased, the plug 51 is lifted upwards, and when the heating temperature of the mocha kettle is controlled, the pressure is lower than the pressing force exerted by the spring 52 on the plug 51 after the pressure in the kettle is reduced, and at the moment, the plug 51 is pressed on the sleeve 6 to be closed.
The adjusting block 31 drives the sleeve 6 to move forward or backward by slightly adjusting the screw-in or screw-out, so that the compression force of the spring 52 on the upper flow limiting plug 5 generates the change of tightness adjustment, thereby achieving the purpose of adjusting the pressure of the extracted coffee in the kettle and the water temperature and water pressure of the extracted coffee, and further meeting the requirements of the user on the coffee cooking taste.
The above examples are merely illustrative of the preferred embodiments of the present utility model and are not intended to limit the spirit and scope of the present utility model. Various modifications and improvements of the technical scheme of the present utility model will fall within the protection scope of the present utility model without departing from the design concept of the present utility model, and the technical content of the present utility model is fully described in the claims.
