It should be understood that, in addition to the configuration of the present embodiment, the switching connector 600 may have other configurations, for example, the switching switch is a toggle switching type switching connector 600.

Referring to fig. 2 and 4, in some embodiments of the present utility model, the switch connector 600 includes a body portion 610, an elastic member 620, a hollow column 630, and a switch button 640, where the switch button 640 is a switch, the body portion 610 is provided with a connection cavity 614, the lower end of the body portion 610 is provided with an output port 611, the output port 611 is communicated with the connection cavity 614, a side wall of the body portion 610 is provided with a first inlet 612 and a second inlet 613, the first inlet 612 and the second inlet 613 are both communicated with the connection cavity 614, the hollow column 630 is slidingly connected in the connection cavity 614 of the body portion 610, the switch button 640 is connected with the hollow column 630, the switch button 640 is used for driving the hollow column 630 to slide relative to the body portion 610, one end of the elastic member 620 is connected with the hollow column 630, the other end of the elastic member 620 is connected with the switch button 640 or the body portion 610, the hollow column 630 is provided with a switch cavity 631 with an opening at one end, the switch cavity 631 is communicated with the output port 611 through an opening, the outer side wall of the hollow column 630 is provided with a first sealing ring 632 and a second sealing ring 633, the first sealing ring 632 and the second sealing ring 633 are both abutted against the side wall of the connection cavity 614, the first sealing ring 632 and the second sealing ring 633 are provided with the sealing ring 633, the first sealing ring and the second sealing ring 633 are disposed on the outer side wall of the hollow column 630, the hollow column 630 is far from the opening, the opening is sealed, which is communicated with the opening, and is sealed.

Referring to fig. 4, when the switch button 640 is not pressed, the switch cavity 631 (or the switch button 640, the hollow column 630) is far away from the output port 611 of the body 610, and the closed space 650 is communicated with the second inlet 613, so that the second inlet 613 is closed, and the substance input by the second inlet 613 cannot be transmitted to the output port 611, and the first inlet 612 can be directly communicated to the output port 611 at this time, so that the output port 611 will only output the substance input by the first inlet 612; when the switch button 640 is pressed, the switch cavity 631 (or the switch button 640, the hollow column 630) is close to the output port 611 of the body 610, the closed space 650 is communicated with the first inlet 612, so that the first inlet 612 is closed, and the substance input by the first inlet 612 cannot be transmitted to the output port 611, while the second inlet 613 can be communicated with the switch cavity 631 through the switch opening 634 and then is communicated with the output port 611 through the switch cavity 631, so that the output port 611 only outputs the substance input by the second inlet 613. And the elastic member 620 is used to reset the switching button 640, in this embodiment, when the switching button 640 is pressed, the elastic member 620 is compressed, and when the switching button 640 is not pressed, the compressed elastic member 620 releases the elasticity, thereby moving the switching button 640 to a side away from the output port 611 of the body portion 610. Therefore, the switching connector 600 is provided to realize the function of switching the gas or water supplying flushing camera 310.

Referring to fig. 2 and 4, the switching button 640 is provided with a vent hole 660, one end opening of the vent hole 660 is located on the pressing surface of the switching button 640, one end of the vent hole 660 is used for communicating with the outside, both ends of the hollow column 630 are provided with openings, the switching cavity 631 communicates with the output port 611 through the opening of one end of the hollow column 630, the other end of the vent hole 660 communicates with the switching cavity 631 through the opening of the other end of the hollow column 630, and the elastic member 620 is used for automatically communicating the closed space 650 with the second access port 613.

Referring to the foregoing, the first inlet 612 is vented and the second inlet 613 is vented. When the switch button 640 is not pressed, the closed space 650 automatically communicates with the second inlet 613 (i.e., only the switch connector 600 is ventilated at this time) due to the action of the elastic member 620; at this time, when the vent 660 can communicate with the outside, the gas inputted from the first inlet 612 into the interior (connection cavity 614) of the switching connector 600 has two (upper and lower) outlet paths: one enters the switching cavity 631 of the hollow column 630 through the opening at the lower end of the hollow column 630, then enters the vent hole 660 through the opening at the upper end of the hollow column 630, and finally enters the outside through the vent hole 660; the other is that the connecting cavity 614 enters the inner connecting tube through the output port 611 of the body portion 610, and then enters the nozzle 400 of the tip through the inner connecting tube. The inner diameters of the interconnecting pipe and the nozzle 400 are smaller (relative to the switching inner cavity 631 and the ventilation hole 660), the inner diameters of the switching inner cavity 631 and the ventilation hole 660 are larger, the overall path from the first inlet 612 to the nozzle 400 for ejecting outside is longer, and the overall path from the first inlet 612 to the ventilation hole 660 for ejecting outside is shorter, so that the gas introduced into the switching connector 600 from the first inlet 612 is basically ejected from the ventilation hole 660 to the outside.

Therefore, by arranging the vent 660, when the switching button 640 is not pressed and the vent 660 can be communicated with the outside, the sprayer 400 inserted into the animal body can not spray gas at will, so that the animal inner cavity is prevented from being excessively inflated, and the animal is prevented from generating discomfort and even danger in the operation. The elastic element 620 makes the closed space 650 automatically communicate with the second inlet 613, on the one hand, the material sprayed to the outside through the air hole 660 is air, which has less influence on the outside, and if water is sprayed, the outside environment, staff and even animals in operation can be greatly influenced; on the other hand, the gas is less affected by gravity, and is conveniently ejected from the vent hole 660. One end opening of the vent 660 is arranged on the pressing surface of the switch button 640, so that when the spray head 400 sprays water and sprays air to clean the camera 310, a worker can conveniently put fingers on the pressing surface of the switch button 640 to block the vent 660, and the normal function of cleaning the camera 310 is realized.
