The assembling process comprises the following steps: fixing the cylinder plug 8 at one end of the main board 51, forming guide grooves 53 on the upper and lower sides of the main board 51 of the fixing plate 5, fixing a suitable hard corrosion-resistant copper wire on the guide grooves 53, and reserving a sufficient length to enable the copper wire extending out of the cylinder plug 8 to be conveniently connected with a signal wire connector of a contactor, so as to form the fixing plate 5 with a trigger function; horizontally inserting the elastic sheet 61 into the window 7 of the main board 51, inserting the four first connecting claws 622 of the upper laryngeal knot 62 downwards into the intersections of the fixed plate 5, inserting the four second connecting claws 632 of the lower laryngeal knot 63 upwards into the intersections of the fixed plate 5, abutting the first connecting claws 622 and the second connecting claws 632 against the elastic sheet 61, and fixedly connecting the three by using fixing glue to form a balance system 6; placing the balance system 6 in the lower groove 21 of the lower shell 2, placing the upper shell 1 on the balance system, aligning and matching the upper groove 11 with the lower groove 21, and then fixedly connecting the upper shell 1 with the lower shell 2 to form a cross-shaped four-way pipeline, wherein at the moment, the right side of the four-way pipeline can be sealed by the column plug 8 to obtain a three-way pipeline; and (3) passing a copper wire through the through hole 81 of the cylinder plug 8 and connecting the copper wire with an external trigger to obtain an integrated tee joint for automatically balancing vacuum pressure and switching a pipeline.

The working principle is as follows: the copper wire extending out of the cylinder stopper 8 is connected to an external contactor and the urinal is connected to the left channel, as shown by the arrow in fig. 1, air (p) enters from the upper channel 3 and the lower channel 4 is connected to a suction device with a delayed suction function. When urine (l) in the urine funnel enters from a left channel of the tee joint under the action of gravity, a trigger connected with the fixing plate 5 generates a trigger signal and starts a suction device to generate vacuum, the vacuum is transmitted to a balance system 6 in the center of the tee joint through the upper channel 3 to suck the urine into the tee joint, when the vacuum pressure is low, due to the fact that the upper throat junction 62 and the elastic sheet 61 are integrated, under the elastic action, a cone 621 of the upper throat junction 62 is in tight contact with a sealing ring 9 in the upper pipeline 3, and a circle of silica gel ring 623 is further arranged on the surface of the cone 621, so that good sealing is formed on the upper pipeline, and air cannot enter the tee joint due to obstruction; when the vacuum in the tee joint reaches a certain degree, the pressure difference between the cone 621 and the upper pipeline of the tee joint can overcome the elastic force of the elastic sheet to press the upper throat 62 downwards, so that the upper pipeline 3 is partially opened, air can enter, the larger the vacuum degree is, the larger the downward moving degree of the balance system 6 is, more air can enter the tee joint, and due to the existence of the silica gel ring 623, when the upper pipeline 3 is partially opened, the entering degree of the air is slowed down, so that the phenomenon that excessive air is blown in one time to cause the balance of the air and urine in the tee joint to be lost is avoided; and because the air is rapidly supplemented, the fluid in the three-way pipe flows to form vacuum, and the three-way pipe can be rapidly expanded, so that the vacuum degree at the position of the balance system 6 is immediately reduced, and the reduction of the vacuum degree also enables the balance system 6 to move upwards under the elastic action, so that the opening degree of the upper pipe 3 of the three-way pipe is reduced, the air flow entering the three-way pipe is reduced, the vacuum degree is increased, and the vacuum degree in the three-way pipe can be generally balanced to a certain extent under the action of the balance system 6. Due to the existence of the balance function, the vacuum degree of the tee joint for sucking the urine funnel is not too large, and the situation that the urine funnel is deflated can be avoided; when the urine is sucked, the suction device has a delayed suction function, so that the vacuum in the tee joint sucks air in the urine funnel (the upper end of the urine funnel is provided with an air inlet, so that the urine funnel cannot be deflated); because the entering air is uniformly dispersed into urine under the action of the balance system 6, and the lower end of the lower throat junction 63 is the circular truncated cone 631, the urine forms a horn-shaped structure in the flow direction through the circular truncated cone 631 and the three-way lower pipeline 4, namely the pipe diameter is gradually enlarged in the flow direction of the fluid, which is very beneficial to forming turbulence, so that the dispersion of the air in the urine can be further promoted, and the density of the urine is reduced; and the side wall of the circular truncated cone 631 has a certain radian, so that a gap for urine to flow in is enlarged in the limited space of the lower channel 4, and the suction speed is improved. After the urine on the left side flows out, the urine enters the tee joint along with the air, and forms equal pressure with the air entering from the upper pipeline 3 of the tee joint, at the moment, the balance system 6 is restored under the action of the elastic sheet 61, the air entering the tee joint from the upper pipeline 3 of the tee joint is blocked again, the automatic switching of the pipelines is achieved, and the tee joint is changed into a two-way joint consisting of a left channel and a lower channel.

While the embodiments of the invention have been disclosed above, it is not limited to the applications listed in the description and the embodiments, which are fully applicable in all kinds of fields where the invention is suitable, and further modifications may readily be made by those skilled in the art, and the invention is therefore not limited to the specific details without departing from the general concept defined by the claims and the scope of equivalents.
