[0007] The flushing shell is a hollow shell structure arranged at the top of the handle body, the bottom communicates with the beginning end of the flushing pipe, and the rear side wall of the flushing shell is provided with a water injection hole along the liquid outlet direction of the handle body; the water baffle is arranged inside the flushing shell between the water injection hole and the beginning end of the flushing pipe, and the surface of the water baffle is provided with a water inlet hole, and the edge position is sealingly connected with the inner side of the flushing shell; the cross section of the closing button is in the form of an H-shaped structure, one end of which is a pressing end and the other end is a water blocking end, the water blocking end of the closing button is arranged between the water baffle and the rear side wall of the flushing shell, and the pressing end of the closing button penetrates through the front side wall of the flushing shell and is located outside the flushing shell; the pressing spring is sleeved on the closing button and located outside the flushing shell, and the two ends thereof abut against the front side wall of the flushing shell and the pressing end of the closing button respectively, thereby providing the closing button with elastic force away from the water injection hole and driving the water blocking end of the closing button to seal the water inlet hole of the water baffle.

[0008] In a specific embodiment, the water baffle has a preset thickness.

[0009] In a specific embodiment, the closing button covers the water inlet hole of the water baffle.

[0010] In a specific embodiment, the closing button comprises a support rod, a pressing end and a water injection end.

[0011] The support rod is in the form of a rod structure; the pressing end is in the form of a plate structure arranged at one end of the support rod, and the plate surface of the pressing end is perpendicular to the length direction of the support rod; and the water injection end is in the form of a plate structure arranged at the other end of the support rod, and the plate surface of the water injection end is perpendicular to the length direction of the support rod.

[0012] In a specific embodiment, the front side wall of the flushing shell is recessed with a spring mounting groove towards the rear side wall of the flushing shell, and the pressing spring is arranged inside the spring mounting groove, and the two ends thereof abut against the bottom wall of the spring mounting groove and the pressing end of the closing button respectively.

[0013] The bottom wall of the spring mounting groove is provided with a pressing hole matched with the support rod.

[0014] In a specific embodiment, the inside of the pressing spring groove is provided with a second sealing ring, the second sealing ring is sleeved on the support rod, and the two ends of the pressing spring abut against the second sealing ring and the pressing end respectively, thereby pressing the second sealing ring to seal the gap between the pressing hole and the support rod.

[0015] In an embodiment, the water-blocking end of the closing button is provided with a first sealing ring adjacent to the plate surface of the water-blocking plate, and the diameter of the first sealing ring is greater than the diameter of the water inlet hole.

[0016] In an embodiment, the water-blocking end of the closing button corresponds to the water injection hole of the flushing shell.

[0017] In an embodiment, the water inlet hole, the water injection hole and the elastic direction of the pressing spring are in the same direction.

[0018] In an embodiment, when the water-blocking end of the closing button abuts against the water-blocking plate, the pressing end of the closing button is spaced apart from the front side wall of the flushing shell by a predetermined distance.

[0019] The flushing aspirator of the embodiment has the following beneficial effects: during use, the pressing spring is in a compressed state, abutting against the pressing end of the closing button away from the water injection hole of the flushing shell, thereby providing a force for the closing button to abut against the water-blocking plate, and at this time, the water inlet hole on the water-blocking plate is in a closed state, and the flushing pipe of the handle main body is in a water-off state. When the closing button is pressed, the pressing force is greater than the elastic force of the pressing spring, which drives the water-blocking end of the closing button away from the water inlet hole on the water-blocking plate, thereby connecting the water injection hole and the flushing pipe of the handle main body. In this way, compared with the conventional method of closing the water flow by extruding the soft rubber material flushing pipe, the application does not need to extrude the flushing pipe, but controls the water flow state by closing the connection between the water injection hole and the flushing pipe, which can solve the problems of aging of the soft pipe, deformation of the soft pipe after long-time extrusion, difficulty in recovery, and the need to set the pressing force according to the hardness of the soft pipe, and the relatively large pressing force reduces the influence of the pressing control force on the user's fine operation.

In some examples, methods, means, elements and circuits well known to those skilled in the art are not described in detail, in order to highlight the main idea of the present application.

[0028] As Figure 1As shown, the flushing aspirator of the embodiment of the present application comprises a handle body 100, a flushing shell 200, a pressing spring 500, a water baffle 300 and a closing button 400. The inside of the handle body 100 is provided with a flushing pipe and an aspirating pipe, the ends of the flushing pipe and the aspirating pipe extend to the outside of the handle body 100, and the end of the aspirating pipe is sleeved outside the end of the flushing pipe, the beginning end is suitable for connecting a negative pressure adjusting part, the flushing shell 200 is a hollow shell structure, is arranged at the top of the handle body 100, the bottom is communicated with the beginning end of the flushing pipe, and the rear side wall of the flushing shell 200 is provided with a water injection hole 210 along the liquid outlet direction of the handle body 100; the water baffle 300 is arranged in the inside of the flushing shell 200, is located between the water injection hole 210 and the beginning end of the flushing pipe, and the face of the water baffle 300 is provided with a water inlet hole, and the edge position is sealingly connected with the inside of the flushing shell 200; the cross section of the closing button 400 is an “H” type structure, one end with a baffle is a pressing end 430, the other end is a water blocking end 410, the water blocking end 410 of the closing button 400 is arranged between the water baffle 300 and the rear side wall of the flushing shell 200, the pressing end 430 of the closing button 400 passes through the front side wall of the flushing shell 200 and is located outside the flushing shell 200; the pressing spring 500 is sleeved on the closing button 400 and is located outside the flushing shell 200, and the two ends are respectively abutted with the front side wall of the flushing shell 200 and the pressing end 430 of the closing button 400, so as to provide the closing button 400 with the elastic force away from the water injection hole 210, drive the water blocking end 410 of the closing button 400 to seal the water inlet hole of the water baffle 300.

[0029] The closing button 400 with the “H” type cross section design makes the button have the pressing function and can automatically seal the water inlet hole when not in use. The pressing end 430 is located outside the flushing shell 200, which is convenient for user operation, and the water blocking end 410 is arranged between the water baffle 300 and the rear side wall of the flushing shell 200. When the button is pressed, the water blocking end 410 will leave the water inlet hole to allow the flushing liquid to pass through. When the button is released, the elastic force provided by the pressing spring 500 will drive the water blocking end 410 to reseal the water inlet hole, so as to realize the on-off control of the flushing function.

[0030] In use, the compression spring 500 is in a compressed state, abutting the pressing end 430 of the closing button 400 away from the water inlet hole 210 of the flushing shell 200, thereby providing a force for the closing button 400 to abut and press the water baffle 300. At this time, the water inlet hole on the water baffle 300 is in a closed state, and the flushing pipe of the handle body 100 is in a water-off state. When the closing button 400 is pressed, the pressing force is greater than the elastic force of the compression spring 500, which drives the water blocking end 410 of the closing button 400 away from the water inlet hole on the water baffle 300, thereby connecting the water inlet hole 210 and the flushing pipe of the handle body 100. In this way, compared with the traditional way of closing the water flow by squeezing the soft rubber material of the flushing pipe, the application does not need to squeeze the flushing pipe, but controls the state of the water flow by closing the communication between the water inlet hole 210 and the beginning of the flushing pipe. This can solve the problems of aging of the hose, deformation of the hose after long-time squeezing, and difficulty in restoring the hose, and the control of the pressing force needs to be set according to the hardness of the hose. The pressing force is relatively large, which reduces the influence of the pressing control force on the fine operation of the user.

[0031] In a specific embodiment, the water baffle 300 is arranged inside the flushing shell 200 between the water inlet hole 210 and the beginning of the flushing pipe, playing a key role in isolation and guidance. The water inlet hole on the surface of the water baffle 300 allows the flushing liquid to pass through, and the sealing connection between the edge position and the inside of the flushing shell 200 effectively prevents liquid leakage. The water baffle 300 has a predetermined thickness, which can keep it from deforming under the impact of water flow, and also ensures the sealing effect between the water inlet hole and the water blocking end 410 of the closing button 400.

[0032] In a specific embodiment, the closing button 400 covers the water inlet hole of the water baffle 300. When the closing button 400 abuts against the water baffle 300, the closing button 400 needs to be completely covered to seal the water inlet hole and prevent water flow from entering the flushing pipe of the handle body 100. When the button is not pressed, the water blocking end 410 tightly fits on the water inlet hole, forming a solid waterproof barrier. When the button is pressed, the water blocking end 410 temporarily leaves the water inlet hole, allowing the flushing liquid to pass through and enter the flushing pipe.

[0033] In one embodiment, the closing button 400 includes a support rod 420, a pressing end 430, and a water injection end. The support rod 420 is a rod-shaped structure used to support the pressing end 430 and the water injection end at both ends, serving as a bridge connecting the pressing end 430 and the water retaining end 410, thereby ensuring the stability and durability of the overall structure. The pressing end 430 is a plate-shaped structure disposed at one end of the support rod 420, with the plate surface perpendicular to the length of the support rod 420, providing a position for the user to press the support column, while the water retaining end 410 is a plate-shaped structure disposed at the other end of the support rod 420, with the plate surface perpendicular to the length of the support rod 420, for contacting with the water retaining plate 300 and sealing the water inlet opening on the water retaining plate 300, thereby effectively blocking the water flow and achieving flexible switching between flushing and stopping, specifically stopping under normal conditions and being able to switch between flushing when flushing is required.

[0034] Furthermore, in this embodiment, a spring 500 mounting groove is recessed in the front sidewall of the flush housing 200, facing the rear sidewall of the flush housing 200. The pressing spring 500 is disposed within the spring 500 mounting groove, with its two ends respectively abutting against the bottom wall of the spring 500 mounting groove and the pressing end 430 of the closing button 400. To ensure smooth operation of the closing button 400, the front sidewall of the flush housing 200 is provided with a spring 500 mounting groove. This groove is recessed toward the rear sidewall of the flush housing 200, and the pressing spring 500 is disposed therein. The two ends of the spring 500 are respectively tightly abutted against the bottom wall of the spring 500 mounting groove and the pressing end 430 of the closing button 400, thereby achieving the automatic reset function of the button. In addition, a pressing hole is formed in the bottom wall of the spring 500 mounting groove to match the support rod 420, allowing the support rod 420 of the closing button 400 to pass through the front sidewall of the flush housing 200.

[0035] Among them, a second sealing ring 600 is provided inside the groove of the pressing spring 500, and the second sealing ring 600 is sleeved on the support rod 420, and the two ends of the pressing spring 500 are respectively in contact with the second sealing ring 600 and the pressing end 430, pressing the second sealing ring 600 to seal the gap between the pressing hole and the support rod 420. During the pressing process, the second sealing ring 600 fits tightly into the gap between the pressing hole and the support rod 420, effectively preventing the infiltration of external moisture, ensuring the overall sealing and durability of the flushing suction device, further improving the sealing performance, and preventing water leakage.

[0036] In a specific embodiment, a first sealing ring is provided on the plate surface of the water retaining end 410 adjacent to the water retaining plate 300. The diameter of the first sealing ring is larger than the diameter of the water inlet, which effectively prevents water from seeping out of the gap and ensures the use effect and safety of the flushing suction device.

[0037] In a specific embodiment, the water-blocking end 410 of the closing button 400 corresponds to the water injection hole 210 of the flushing shell 200, and when water flows into the water injection hole 210 of the flushing shell 200, the water flow provides partial pressure to the water-blocking end 410 of the plate-shaped structure, so that the water-blocking end 410 of the closing button 400 is tightly attached to the plate surface of the water-blocking plate 300.

[0038] Further, in the embodiment, the water inlet hole, the water injection hole 210, and the elastic direction of the pressing spring 500 are in the same direction.

[0039] In a specific embodiment, when the water-blocking end 410 of the closing button 400 is in abutment with the water-blocking plate 300, the pressing end 430 of the closing button 400 is spaced apart from the front side wall of the flushing shell 200 by a predetermined distance, which ensures sufficient pressing space for the button and avoids damage caused by excessive pressing, further improving the service life and safety of the flushing aspirator.

[0040] The above has described the embodiments of the present application, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles, practical applications, or improvements to the technology in the market of the embodiments, or to enable other ordinary skilled persons in the art to understand the embodiments disclosed herein.
