Although "first" or "second" etc. are used in this specification to represent certain features, they are only used to represent the function, and are not used as a limitation on the number and importance of specific features.

[0037] In order to solve the technical problems in the prior art, an embodiment of the present application provides a flushing and aspirating device, including a delivery tube, a flushing tube, a suction tube and a switching structure, one end of the delivery tube is respectively connected to the flushing tube and the suction tube. The switching structure includes a switching control member, and the switching control member is movably arranged between the flushing tube and the suction tube. By driving the switching control member to switch between different position ranges, the flushing function and the suction function can be switched on and off. Specifically, when the switching control member is in a first position range, the switching control member presses to close the suction tube and opens the flushing tube, that is, the flushing function is turned on and the suction function is turned off; when the switching control member is in a second position range, the switching control member presses to close the flushing tube and opens the suction tube, that is, the suction function is turned on and the flushing function is turned off. Therefore, the two pipelines of the flushing tube and the suction tube can be controlled simultaneously by a switching control member, the structure is simple, the cost is reduced while meeting the use requirements, and it is conducive to the wide promotion and application of flushing and aspirating devices.

[0038] The structure of the flushing and aspirating device in one embodiment is described in detail below with reference to the accompanying drawings. It should be understood that the accompanying drawings and the following description are examples and are not intended to limit the scope of protection of this application. Figures 4 to 9 The schematic diagram of the flushing aspirator in different states cut along the A1-A1 direction is shown in order to clearly show the matching relationship of each component. Figures 4 to 9 The axial direction of the switching control member 51 is parallel to the rotation axis 54 of the switching control member 51, that is, Figure 3 The S0 direction in . Figures 4 to 9 What is shown is the structure of the irrigation aspirator in a cross section perpendicular to the S0 direction.

[0039] In this application, "closing" and "opening" a pipeline (flushing tube or suction tube) refer to the control of the conduction state of the pipeline. "Closing" a pipeline means cutting off the communication path inside the pipeline, and the function corresponding to the pipeline (flushing function or suction function) is correspondingly closed. "Opening" a pipeline means keeping the communication path inside the pipeline in a conduction state, including the state of the communication path being fully open and the communication path being partially open, and the function corresponding to the pipeline is correspondingly opened.

[0040] like Figures 1 to 4 As shown, an embodiment of the present application provides a flushing aspirator, including a delivery tube 10, a flushing tube 20, a suction tube 30 and a switching structure 50. One end of the delivery tube 10 is respectively connected to the flushing tube 20 and the suction tube 30 through a three-way joint 40. The switching structure 50 includes a switching seat 52, a knob 53 and a switching control member 51. A cavity for accommodating the switching control member 51 is formed inside the switching seat 52. The switching control member 51 is located in the cavity and is rotatably connected to the switching seat 52. The knob 53 is located outside the switching seat 52 and is connected to the switching control member 51. The outer surface of the knob 53 is provided with anti-slip grooves 532 to facilitate user operation. Figure 3 As shown, the knob 53 and the switch control member 51 are rotatably mounted on the switch seat 52 via a rotating shaft 54, so that when the user rotates the knob 53, the knob 53 drives the switch control member 51 to rotate relative to the switch seat 52. The rotating shaft 54 ​​can be divided into two sections, the upper section connecting the knob 53 and the switch control member 51, and the lower section connecting the switch control member 51 and the switch seat 52, or an integral rotating shaft 54 ​​penetrating the switch control member 51 can be used to simultaneously connect the switch control member 51 to the knob 53 and the switch seat 52.

[0041] like Figure 4 As shown, the flushing tube 20 and the suction tube 30 are respectively partially accommodated in the interior of the switching seat 52, and both ends of the flushing tube 20 are passed out of the switching seat 52, and both ends of the suction tube 30 are passed out of the switching seat 52. The flushing tube 20 and the suction tube 30 are respectively located on both sides of the switching control member 51, so that the switching control member 51 is movably arranged between the flushing tube 20 and the suction tube 30. Figures 3 to 5 As shown, the switching control member 51 is a cam with RO as the rotation center, and the cam can switch between a first position range and a second position range when rotating. Figure 4 The state of the switching control member 51 when it is in the first position range is shown. At this time, the switching control member 51 presses and closes the suction tube 30, while the inside of the flushing tube 20 is connected, that is, the flushing function is turned on and the suction function is turned off. Figure 7The state of the switching control member 51 when it is in the second position range is shown. At this time, the switching control member 51 presses and closes the flushing tube 20, while the internal conduction of the suction tube 30 is turned on, that is, the suction function is turned on and the flushing function is turned off. Therefore, the present application realizes the simultaneous control of the two pipelines of the flushing tube 20 and the suction tube 30 through a switching control member 51. By driving the switching control member 51 to switch between different position ranges, the flushing function and the suction function can be switched on and off. Since the switching structure 50 of the present application only needs to provide one switching control member 51, only a single knob 53 needs to be set accordingly, and the user only needs to operate the knob 53 to meet the use requirements. Therefore, the flushing aspirator using the switching structure 50 has a simple structure, reduces the cost while meeting the use requirements, and is conducive to the wide promotion and application of the flushing aspirator.

[0042] like Figure 4 and Figure 5 As shown, the switching control member 51 includes a first surface 511 and a second surface 512. The first surface 511 and the second surface 512 have a boundary line on both sides, and the part of the boundary line on both sides is defined as belonging to the first surface 511, and the second surface 512 refers to the curved surface part that does not include the boundary line on both sides of the second surface 512 and the first surface 511. When the switching control member 51 is in the first position range, the first surface 511 abuts against the suction tube 30 to close the suction tube 30, and the second surface 512 is opposite to the flushing tube 20 to open the flushing tube 20. When the switching control member 51 is in the second position range, the first surface 511 abuts against the flushing tube 20 to close the flushing tube 20, and the second surface 512 is opposite to the suction tube 30 to open the suction tube 30.

[0043] Therefore, the first surface 511 is equivalent to the closing control surface of the switching control member 51, and the second surface 512 is equivalent to the opening control surface of the switching control member 51. In this embodiment, the first position range and the second position range do not refer to specific position points, but refer to a position interval of the switching control member 51 within a certain rotation angle. The first position range refers to the position interval where the first surface 511 abuts against the suction tube 30 and the second surface 512 is opposite to the flushing tube 20, and the second position range refers to the position interval where the first surface 511 abuts against the flushing tube 20 and the second surface 512 is opposite to the suction tube 30.

[0044] like Figure 4 and Figure 5 As shown, in a cross section perpendicular to the axial direction of the switching control member 51, there is a first distance (eg, Figure 5There is a second distance (eg, d1) between the position point of the second surface 512 and the rotation center RO of the switching control member 51. Figure 5 The first distance is greater than the second distance, that is, the first surface 511 protrudes further outward relative to the rotation center RO than the second surface 512. The rotation center RO can be optionally set at the middle position between the flushing tube 20 and the suction tube 30, but the present application is not limited thereto.

[0045] Specifically, Figure 4 As shown, when the switching control member 51 is in the first position range, the first surface 511 abuts against the suction tube 30, pressing one side wall of the suction tube 30 toward the other side until the two sides of the suction tube 30 fit together, thereby cutting off the connecting passage in the suction tube 30, that is, closing the suction tube 30 and the suction function. The second surface 512 is opposite to the flushing tube 20, but does not close the flushing tube 20, and the flushing tube 20 remains conductive, that is, the flushing function remains turned on. Figure 7 As shown, when the switching control member 51 is in the second position range, the first surface 511 abuts against the flushing tube 20, pressing one side wall of the flushing tube 20 toward the other side until the two sides of the flushing tube 20 fit together, thereby cutting off the communication path in the flushing tube 20, that is, closing the flushing tube 20 and the flushing function. The second surface 512 is opposite to the suction tube 30, but does not close the suction tube 30, and the suction tube 30 remains unobstructed, that is, the suction function remains on.

[0046] like Figure 5 As shown, the first surface 511 may be an arc surface, and on a cross section perpendicular to the axial direction of the switching control member 51, the first distances between each position point of the first surface 511 and the rotation center RO of the switching control member 51 are the same, that is, they are all equal to d1, so that when each position of the first surface 511 contacts the suction tube 30, the suction tube 30 can be closed, and when each position of the first surface 511 contacts the flushing tube 20, the flushing tube 20 can be closed. In addition, since the first surface 511 is a smooth surface, the first surface 511 can slide smoothly when rotating relative to the closed pipeline, making the knob operation smoother and avoiding damage to the contacted pipeline.

[0047] like Fig. 9 As shown, the central angle a1 corresponding to the first surface 511 is greater than 180°. Figure 6 and Figure 8As shown, between the first position range and the second position range, the movable range of the switching control member 51 also has the third position range. When the switching control member 51 is in the third position range, the first surface 511 simultaneously abuts against and closes the flushing tube 20 and the suction tube 30, and simultaneously closes the flushing function and the suction function.

[0048] Figure 4 , Figure 6 , Figure 7 to Figure 8 The figure shows the various states of the switching control member 51 in one rotation cycle. Figure 4 In the state (the switch control member 51 is in the first position range), only the flushing function is turned on, along Figure 4 Rotate the switch control member 51 counterclockwise to Figure 6 The state (the switch control member 51 is in the third position range), the flushing and suction functions are turned off at the same time, and the Figure 6 Continue to rotate the switching control member 51 in the counterclockwise direction to reach Figure 7 The state (the switch control member 51 is in the second position range), only the suction function is turned on, along Figure 7 Continue to rotate the switching control member 51 in the counterclockwise direction to reach Figure 8 The state (the switch control member 51 is in the third position range), the flushing and suction functions are turned off again at the same time, and the Figure 8 If the switching control member 51 is rotated counterclockwise, the Figure 4 Therefore, by rotating the switching control member 51, the user can switch the flushing and suction device between the three states of only turning on the flushing function, turning off both the flushing and suction functions, and turning on the suction function only, making the operation more flexible and convenient. At the same time, since the central angle a2 corresponding to the second surface 512 is less than 180°, there is no situation where the second surface 512 is opposite to the flushing tube 20 and the suction tube 30 at the same time, and it is impossible to turn on the flushing function and the suction function at the same time.

[0049] like Figure 5 As shown, the second surface 512 is a curved surface. On a cross section perpendicular to the axial direction of the switching control member 51, from the center point of the second surface 512 to both sides, the second distance between each position point of the second surface 512 and the rotation center RO of the switching control member 51 gradually increases. That is, for the second surface 512, the distance from the center point of the second surface 512 to the rotation center RO ( Figure 5The distance d3) of the second surface 512 is the smallest, and the distances from each position point of the second surface 512 to the rotation center RO gradually increase from the center point of the second surface 512 to the intersection point of the second surface 512 and the first surface 511. The distance d3 from the center point of the second surface 512 to the rotation center RO is smaller than the distances from other position points of the second surface 512 to the rotation center RO (such as Figure 5 Thus, when the second surface 512 is opposite to a pipeline (flushing tube 20 or suction tube 30), and different positions of the second surface 512 are opposite to the pipeline by rotating the switching control member 51, the conduction conditions of the pipeline are different. The larger the second distance corresponding to the position point opposite to the pipeline, the greater the degree to which the pipeline is compressed by the second surface 512, the smaller the conduction diameter of the pipeline, and the smaller the conduction flow rate therein. Figure 4 For example, when the center point of the second surface 512 is opposite to the flushing tube 20, the flushing tube 20 is not squeezed at all, and the flushing tube 20 is at its most conductive. Figure 4 In the state of rotating the switching control member 51 clockwise or counterclockwise, other positions of the second surface 512 are opposite to the flushing tube 20 and compress the wall of the flushing tube 20 to a certain extent. The wall of the flushing tube 20 is squeezed to reduce the conduction diameter, but it is not completely closed. Depending on the degree of compression, the degree of reduction of the flow in the flushing tube 20 is different. Figure 7 For example, when the center point of the second surface 512 is opposite to the suction tube 30, the suction tube 30 is not squeezed at all, so that the suction tube 30 is conductive to the maximum extent. Figure 7 When the switching control member 51 is rotated clockwise or counterclockwise in the state, other positions of the second surface 512 are opposite to the suction tube 30 and compress the tube wall of the suction tube 30 to a certain extent. Although the tube wall of the suction tube 30 is squeezed to reduce the conduction diameter, it is not completely closed. The degree of reduction of the flow in the suction tube 30 varies according to the degree of compression. Since the second distance from each position point of the second surface 512 to the rotation center RO changes smoothly, when the switching control member 51 is rotated, the conduction flow of the pipeline opposite to the second surface 512 can be controlled to increase or decrease linearly.

[0050] like Figure 1As shown, the switching structure 50 also includes a flow indicating portion, and the flow indicating portion is provided with a pointer 521 and a flow indicating area 531. When the switching control member 51 rotates, the pointer 521 points to different positions of the flow indicating area 531. The flow indicating area 531 may include a sub-area corresponding to a flushing function and a sub-area corresponding to a suction function, and "flushing" and "suction" marks are respectively set in these two sub-areas. When the switching control member 51 is in the first position range, the pointer 521 points to the sub-area corresponding to the flushing function, and when the switching control member 51 is in the second position range, the pointer 521 points to the sub-area corresponding to the suction function.

[0051] Since the switching control member 51 can control the flow of the flushing tube 20 to increase or decrease linearly when rotating within the first position range, the flow indication area 531 can display multiple scales in the sub-area corresponding to the flushing function to indicate the conduction degree (conduction flow size) of the flushing tube 20. Similarly, when the switching control member 51 rotates within the second position range, the flow of the suction tube 30 can be controlled to increase or decrease linearly, and the flow indication area 531 can display multiple scales in the sub-area corresponding to the suction function to indicate the conduction degree (conduction flow size) of the suction tube 30. The sub-area and scale pointed by the pointer 521 can respectively indicate the function currently turned on by the flushing and suction device and the conduction flow size corresponding to the function. Since the second distance of the center point position of the second surface in this embodiment is the smallest, the scale value corresponding to the center point of each sub-area is the largest, indicating that the conduction flow is the largest, and the scales from each sub-area to both sides gradually decrease, which also reflects the linear adjustment process of the pipeline conduction flow by the switching control member.

[0052] In this embodiment, the pointer 521 is disposed on the switch seat 52, and the flow indication area 531 is disposed on the knob 53, so that the flow indication area 531 can rotate relative to the pointer 521. In another alternative embodiment, the pointer 521 can also be disposed on the knob 53, and the flow indication area 531 can be disposed on the portion of the switch seat 52 not blocked by the knob 53, which can also achieve the purpose of flow indication and also falls within the protection scope of the present application.

[0053] The above content is a further detailed description of the present application in combination with specific preferred implementation methods, and it cannot be determined that the specific implementation of the present application is limited to these descriptions. For ordinary technicians in the technical field to which the present application belongs, several simple deductions or substitutions can be made without departing from the concept of the present application, which should be deemed to fall within the scope of protection of the present application.
