[0021] The embodiments of the present application will be described in further detail below with reference to the accompanying drawings and embodiments. The following detailed description of the embodiments and the accompanying drawings provide for exemplary illustration of the principles of the present application, but are not intended to limit the scope of the present application, which can be realized in many different forms, not limited to the specific embodiments disclosed herein, but include all technical solutions falling within the scope of the claims.

[0022] The present application provides these embodiments in order to make the present application thorough and complete, and fully express the scope of the present application to those skilled in the art. It should be noted that: unless otherwise specified, the relative arrangement of components and steps, the composition of materials, numerical expressions and values set forth in these embodiments should be interpreted as merely exemplary, and not as a limitation.

[0023] It should be noted that, in the description of the present application, unless otherwise specified, the meaning of "a plurality of" is greater than or equal to two; the orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", "inner", "outer" and the like is only for the purpose of facilitating the description of the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. When the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0024] In addition, "first", "second", and similar words used in the present application do not indicate any order, number or importance, but are only used to distinguish different parts. "Vertical" is not strictly vertical, but within the allowable range of error. "Parallel" is not strictly parallel, but within the allowable range of error. "Include" or "contain" and similar words mean that the elements before the word cover the elements listed after the word, and do not exclude the possibility of also covering other elements.

[0025] It should also be noted that, in the description of the present application, unless otherwise specified and limited, the terms "mounting", "connecting", "connection" should be interpreted broadly, for example, it can be a fixed connection, or a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances. When it is described that a specific device is located between a first device and a second device, there can be an intermediate device between the specific device and the first device or the second device, or there can be no intermediate device.

[0026] All terms used in this application have the same meaning as understood by one of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having meanings consistent with their meanings in the context of the relevant art, and not as idealized or highly formalized, unless expressly defined herein.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0028] like Figures 1-4 The illustration shows a flushing aspirator with a switch, comprising a handle housing 1, a liquid channel 2, and a push switch 3. The liquid channel 2 is disposed within the handle housing 1, and an inlet 4 is provided on one side of the liquid channel 2. The push switch 3 is disposed at one end near the inlet 4 and passes through the handle housing 1. The push switch 3 includes a plunger 301 and a locking mechanism 302. The plunger 301 is movably disposed within the liquid channel 2, and the locking mechanism 302 includes a snap-fit ​​male connector 3021 and a snap-fit ​​body. 3022, the male buckle 3021 is disposed on the press switch 3, and the buckle body 3022 is disposed in the handle housing 1 corresponding to the male buckle 3021. The press switch 3 controls the plunger 301 to move in the liquid channel 2. When the plunger 301 moves away from the liquid inlet 4, the liquid enters the liquid channel 2 through the liquid inlet 4; when the plunger 301 moves close to the liquid inlet 4, the plunger 301 blocks the liquid inlet 4, blocking the liquid from entering the liquid channel 2. This allows doctors to quickly and conveniently control the switch of the irrigation water flow, making the surgical process smoother.

[0029] Specifically, an elastic element 5 is provided between the push switch 3 and the liquid channel 2 to move the plunger away from the liquid inlet 4, and a limit boss 6 is provided on both the liquid channel 2 and the push switch 3.

[0030] Furthermore, the elastic element 5 is a spring, which is sleeved on the liquid channel 2 and located between the liquid channel 2 and the limiting boss 6 of the push switch 3. By setting the elastic element, the plunger is moved away from the liquid inlet to keep the water passage unobstructed.

[0031] Specifically, the plunger 301 is provided with two sets of slots 7 at intervals. The interval between the slots 7 is greater than the inner diameter of the liquid inlet 4, which can effectively block the liquid inlet 4, preventing liquid from entering the liquid channel and disconnecting the water circuit.

[0032] Specifically, a sealing ring 8 is fitted onto the slot 7 to effectively improve the sealing performance.

[0033] Specifically, the liquid inlet 4 is vertically arranged with the liquid channel 2.

[0034] Specifically, the liquid channel 2 is sleeved with a bell joint 9, which is conducive to improving the sealing performance of the flusher.

[0035] Specifically, the button of the press switch 3 is arranged outside the handle shell 1 and close to the upper end of the handle shell 1.

[0036] Working principle: when the plunger 301 is away from the liquid inlet 4, liquid enters the liquid channel 2 through the liquid inlet 4 to form a flushing water path; pressing the press switch 3 will press the buckle male head 3021 into the buckle body 3022, and the buckle body 3022 will lock and fix the buckle male head 3021, so that the plunger 301 blocks the liquid inlet 4 to block the liquid from entering the liquid channel 2, and the water path is disconnected. If subsequent flushing is needed, pressing the press switch 3 again will make the buckle male head 3021 away from the buckle body 3022, and drive the plunger 301 away from the liquid inlet 4 to restore the flushing water path, which is convenient for doctors to quickly and conveniently control the switch of the flushing water flow, and makes the surgical process more smooth.

In order to avoid obscuring the concept of the present application, some details known in the art are not described. Those skilled in the art can fully understand how to implement the technical solutions disclosed herein according to the above description.
