For the water jet air extraction vacuum device 1, the water jet pipe 12 is arranged in the air extraction chamber 11, two ends of the water jet pipe 12 are respectively connected with the water inlet 11a and the water outlet 11b, the water jet pipe 12 is provided with a plurality of air extraction holes 121 which are uniformly distributed, and water flow is ejected from the water inlet 11a at a high speed, so that a vacuum negative pressure environment is formed around the water jet pipe 12.
The utility model discloses a solar energy air extracting device, including extraction chamber 11, extraction chamber 13, a plurality of antennas 131, extraction chamber 13, a plurality of air extracting spaces P, an air extracting chamber S is provided with in the extraction chamber 11, is provided with in the extraction chamber S and extracts air storehouse 13, extraction chamber 13 is hollow structure, and extraction chamber 13 sets up and can rotate around injection pipe 12, extraction chamber 13 has a plurality of antennas 131 that can all the time with the lateral wall sliding contact of extraction chamber S, and the part of extraction chamber 13 between two adjacent antennas 131 is the bulkhead, therefore two adjacent antennas 131, extraction chamber S lateral wall, extraction chamber 13 have injectd an air extracting space P, a plurality of air extracting spaces P in the extraction chamber S are independent confined space. The air pumping bin 13 is provided with an air inlet structure 132 on the bin wall corresponding to each air pumping space P, and the air inlet structure 132 allows water vapor to enter the air pumping bin 13 from the air pumping space P. The lateral wall of air extraction cavity S is equipped with a plurality of air inlets 11c, and air inlet 11c passes through trachea 14 and draws in steam from condenser 6, when air extraction storehouse 13 rotated, feeler 131 passed through air inlet 11c in proper order, and when air extraction space P corresponded last feeler 131 entered air inlet 11c, this air extraction space P and air inlet 11c intercommunication were drawn water gas and got into air extraction space P by air inlet 11c in, then got into air extraction storehouse 13 by inlet structure 132 in again, the steam that gets into air extraction storehouse 13 got into in injection pipe 12 under the effect of the vacuum negative pressure environment that forms around injection pipe 12, got into injection pipe 12 by extraction opening 121 to jet out along with the rivers.
In this embodiment, the moisture in the pumping space P enters the pumping chamber 13 from the air inlet structure 132 and is pumped away by the water injection pipe 12 under the action of the vacuum negative pressure environment around the water injection pipe 12, so that the internal air pressure of the pumping space P is reduced before the next air intake, when the pumping space P is communicated with the next air inlet 11c, a stable air pressure difference is formed between the pumping space P and the air inlet 11c, and therefore, the air intake efficiency of the air inlet 11c can be improved, and the multiple air inlets 11c convey moisture to each pumping space P in a circulating manner, thereby comprehensively improving the air pumping efficiency.
Further, the volume of the pumping space P periodically increases and decreases with the rotation of the pumping chamber 13, and the pumping space P communicates with the intake port 11c during the increase in volume and is disconnected from the intake port 11c before the decrease in volume. The air pressure in the air extracting space P can be improved when air is introduced into the air extracting space P, so that the air pressure difference between the air extracting space P and the air inlet 11c is reduced, the volume of the air extracting space P is increased continuously while air is introduced, the increase of the air pressure is reduced, and the total air input of the air extracting space P is facilitated.

In the period when the relief valve is closed, the negative pressure vacuum environment around the water injection pipe 12 can be recovered to a certain degree, so that the air exhaust performance of the water injection pipe 12 can be intermittently recovered, and therefore the air intake structure 132 is set to be in an intermittent air exhaust mode by the relief valve, and the air exhaust efficiency can be further improved.
Because the internal air pressure of the air pumping space P is gradually increased in the air intake process, so that the air pressure difference between the air pumping space P and the air inlet 11c is gradually reduced, the air intake rate of the air inlet 11c is gradually reduced, and based on this, the volume change periods of each air pumping space P are asynchronous, and the air intake synchronization of the air inlet 11c can be avoided.

In addition, the number of the air inlets 11c is the same as the number of cycles that the air pumping space P undergoes after the air pumping bin 13 rotates for a whole circle, so that the air pumping space P is subjected to air inlet once in the process of increasing and reducing the volume once along with the rotation of the air pumping bin 13, and the whole air pumping efficiency is improved.
