the injector 200 comprises a tube 210, an injection member 220, a mixing member 230 and a liquid outlet member 240; the tube 210 includes a first channel 211, a second channel 212, and a third channel 213, the first channel 211 and the second channel 212 are both connected to the third channel 213, and an axis of the first channel 211 coincides with an axis of the third channel 213; the inner diameter of the first passage 211 gradually decreases in a direction from the first passage 211 to the second passage 212; along the direction from the first channel 211 to the second channel 212, the injection member 220 and the mixing member 230 are sequentially arranged in the second channel 212, and the liquid outlet member 240 is detachably connected to one end of the third channel 213, which is away from the first channel 211; the injection piece 220 is abutted against the small-diameter end of the first channel 211, and the injection piece 220 is provided with a fourth channel 221 communicated with the first channel 211; the end of the mixing member 230 facing the first channel 211 and the injection member 220 together define a mixing chamber 222 communicated with the fourth channel 221 and the second channel 212; the mixing member 230 is provided with a fifth passage 231 communicating with the mixing chamber 222; the liquid outlet member 240 is provided with a sixth channel 241 communicated with the fifth channel 231.

When the first channel 211 and the second channel 212 are both communicated with the external liquid supply pipeline, the liquid in the external liquid supply pipeline enters the first channel 211 and the second channel 212 respectively, and the injection piece 220 and the mixing piece 230 in the tube body 210 together form a mixing cavity 222 communicated with the second channel 212, and the mixing cavity 222 is communicated with the second channel 212, the fourth channel 221 and the fifth channel;

therefore, when the liquid in the first channel 211 enters the fifth channel 231 through the third channel 213 and the mixing cavity 222, the liquid in the second channel 212 can be sucked into the mixing cavity 222 under the pressure action of the liquid, and is mixed with the liquid in the mixing cavity 222 input from the first channel 211, and is conveyed to the fifth channel 231 and finally conveyed to the sixth channel 241. It should be noted that, in this embodiment, an end of the first channel 211 departing from the third channel 213 is a first liquid inlet, an end of the second channel 212 departing from the third channel 213 is a second liquid inlet, an end of the third channel 213 departing from the first channel 211 is a liquid outlet, and the liquid conveyed to the sixth channel 241 can be output through the liquid outlet or conveyed to a next structure.

It should be noted that, in the using process, in order to prevent impurities in the external pipe from entering the injector 200 through the first passage 211 and the second passage 212, a filter screen may be disposed in the first passage 211, or a filter screen may be disposed in the second passage 212; in addition, in order to facilitate installation of the filter screens in the first and

second channels

211 and 212, the first and

second channels

211 and 212 are provided with installation grooves or installation platforms at the connection ends with the external pipes, i.e., at the first and second liquid inlets in the above description, so as to facilitate installation of the filter screens.

Further, referring to fig. 1 to 6, in the present embodiment, when the liquid outlet member 240 is disposed, in order to enable the liquid outlet member 240 to be removed during the maintenance of the injection member 220, an end of the liquid outlet member 240 facing the first channel 211 and an end of the third channel 213 departing from the first channel 211 are screwed; and one end of the liquid outlet member 240 facing the first channel 211 is provided with a mounting groove 242, and one end of the mixing member 230 facing away from the first channel 211 is matched with the mounting groove 242. It should be noted that, in order to detachably connect the liquid outlet member 240 and the tube 210, in other embodiments of the present invention, a nut or other detachable connection manner may also be adopted.

Referring to fig. 1 to 6, in the present embodiment, a mixing cavity 222 is formed at a position where the liquid outlet member 240 and the mixing member 230 abut against each other, and the mixing cavity 222 is ensured to be communicated with the second channel 212, the fourth channel 221 and the fifth channel 231, so that an abutting portion 232 abutting against the injection member 220 is disposed at one end of the mixing member 230 facing the first channel 211, the abutting portion 232 protrudes out of the mixing member 230 in a direction facing the first channel 211, the abutting portion 232 faces the second channel 212, and the abutting portion 232 and the injection member 220 define the mixing cavity 222 together with a portion facing the second channel 212.

It should be noted that, since the small diameter end of the first channel 211 abuts against the injection member 220, and the axis of the first channel 211 coincides with the axis of the second channel 212, when the liquid in the first channel 211 enters the fifth channel 231 through the fourth channel 221 and the mixing cavity 222, a suction force is generated due to the increase of the pressure, so that the liquid in the second channel 212 is sucked into the mixing cavity 222, and the liquid in the mixing cavity 222 inputted from the first channel 211 and the liquid inputted from the second channel 212 can be mixed and enter the fifth channel 231 from the mixing cavity 222. When the fourth channel 221, the fifth channel 231, and the sixth channel 241 are provided, the axes thereof are all arranged so as to coincide with the axis of the second channel 212. Also in this embodiment, the axis of the second channel 212 is perpendicular to the axis of the third channel 213, and the mixing chamber 222 is directly opposite the second channel 212.

Referring to fig. 1 to 6, in the present embodiment, when the liquid outlet member 240 and the mixing member 230 are disposed, the liquid outlet member 240 and the mixing member 230 can be attached to the inner wall of the third channel 213, that is, the outer diameter of the injection member 220 and the outer diameter of the mixing member 230 are both smaller than or equal to the inner diameter of the second channel 212. Therefore, when the injection member 220 abuts against the small-diameter section of the first passage 211, the outer diameter of the small-diameter end of the first passage 211 is smaller than the inner diameter of the third passage 213 in order to prevent the injection member from slipping out of the first passage 211.

Further, referring to fig. 1-6, in the present embodiment, when the fourth channel 221 is disposed, referring to the disposition principle of the first channel 211, in the present embodiment, the fourth channel 221 on the injection member 220 may be disposed by using the same principle as the first channel 211, that is, the inner diameter of the fourth channel 221 is gradually reduced along the direction from the first channel 211 to the second channel 212. And the slope of the fourth channel 221 is the same as that of the first channel 211 so that the inner wall of the first channel 211 is continuous with the inner wall of the second channel 212; in addition, the end of the fifth channel 231 facing the first channel 211 is provided with a liquid guiding slope 233, which aims to enable the liquid input by the first channel 211 and the liquid input by the second channel 212 to be quickly guided into the fifth channel 231 after entering the mixing cavity 222; the liquid guiding slope 233 is an annular slope provided around the axis of the fifth passage 231;

besides, when the injection member 220 is disposed, one end of the injection member 220 away from the first channel 211 can be extended into the fifth channel 231, that is, one end of the injection member 220 away from the first channel 211 is extended into an area surrounded by the annular liquid guide inclined plane 233, so that one end of the fourth channel 221 away from the first channel 211 can be located in the fifth channel 231, and the inner circumferential surface of the fifth channel 231 opposite to the end of the injection member 220 away from the first channel 211 is provided with the liquid guide inclined plane 233, and by such an arrangement, the flow rate of the liquid can be accelerated, and the suction force of the liquid input from the first channel 211 to the liquid input from the second channel 212 can be increased.

Based on the above, referring to fig. 1 to fig. 6, in the present embodiment, when the sixth channel 241 is disposed, in order to increase the liquid output amount of the liquid output member 240, the inner diameter of the sixth channel 241 gradually increases along the direction from the first channel 211 to the second channel 212. Furthermore, it should be noted that, in the present embodiment, the injection member 220 and the mixing member 230 are both disposed in the third channel 213, so as to improve the sealing performance of the third channel 213 and prevent the third channel 213 from leaking, therefore, the injector 200 further includes a sealing member, which may be a sealing rubber ring, and the sealing member is sleeved on the mixing member 230.

In order to improve the sealing performance of the injector 200, on the basis of arranging a sealing element between the contact surfaces of the mixing member 230 and the third passage 213, a sealing structure may be arranged at the abutting part of the injection member 220 and the injection member 220 or between the contact surfaces of the injection member 220 and the third passage 213; at the same time, a sealing structure is also provided between the contact surfaces of the third channel 213 of the liquid outlet member 240. Wherein, the sealing structure can adopt a sealing rubber ring the same as the sealing element
