Description

Technical Field

[0001] This invention relates to the field of atomization jet technology, and more particularly to a multi-angle smoke jet machine. Background Technology

[0002] A smoke sprayer is a device that converts liquid medicine, tar, or other functional liquids into smoke and sprays it onto a target area. It is widely used in epidemic prevention and disinfection, environmental maintenance, and stage performances. The smoke is generated and sprayed by the atomizer to cover the target area.

[0003] Existing smoke generators typically use an atomizing device to convert liquid smoke into vapor, which is then emitted through nozzles to create a smoke effect in a designated area. Due to factors such as the desired smoke effect, nozzle unobstructed access, and ease of equipment placement, the spray direction of existing smoke generators usually remains largely unchanged after installation. However, in special applications such as epidemic prevention and disinfection, and stage performances, it is often necessary to adapt the smoke spray direction to meet site requirements and achieve targeted spraying of specific areas.

[0004] If the spray direction is fixed, changing it requires moving the entire atomizer, readjusting the equipment's angle, or altering its installation location. This is not only inconvenient but may also affect the smoke effect. Adjusting the spray direction by changing the nozzle is problematic because the nozzle, being a component connected to the internal atomizing device, is limited by the available installation space and connections. Therefore, achieving convenient and flexible adjustment of the spray direction while ensuring structural integration and normal spraying, and improving the adaptability of the smoke generator to complex spraying scenarios, has become a key technical challenge in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-angle smoke jetting machine that solves the problem that existing smoke jetting machines cannot achieve spray head direction adjustment while ensuring equipment structure integration and normal spraying.

[0006] To achieve this objective, the present invention adopts the following technical solution: A multi-angle smoke jetting machine includes a body, an atomizing generator disposed within the body, and a jetting head communicating with the atomizing generator. A mounting cavity communicating with the outside is provided on one side of the body. A rotating cylinder is rotatably disposed within the mounting cavity. A rotating seat is fitted on the rotating cylinder. The jetting head is disposed on the rotating seat. The jetting head is connected to the atomizing generator through a connecting pipe. The connecting pipe includes a rotating section communicating with the atomizing generator and a connecting section communicating with the spray head. The rotating section is located in the rotating drum and is coaxially arranged with the rotating drum. The body is provided with a rotating part, which is used to drive the rotating seat to rotate around the axis of the rotating cylinder. The rotating section is connected to the atomizing generator through the rotating part. When the angle of the connecting section of the connecting pipe changes, the rotating part is used to keep the rotating section and the atomizing generator in a connected and sealed state.

[0007] Optionally, the machine body has an arc-shaped hole communicating with the mounting cavity, and the rotating part includes a rotating rod fixedly connected to the rotating seat. The rotating rod passes through the arc-shaped hole, and the circle of the arc-shaped hole coincides with the axis of the rotating drum.

[0008] Optionally, the rotating part includes a rotary joint, and the end of the connecting tube near the rotating section is connected to the atomizer via the rotary joint.

[0009] Optionally, the rotating part includes: The gear is fixedly sleeved on the outside of the rotating drum; A semi-gear ring is fixedly connected to the rotating rod, the semi-gear ring meshes with the gear, and the center of the semi-gear ring coincides with the axis of the rotating drum; A drive component is fixedly connected to the machine body, and the drive component is connected to the gear transmission.

[0010] Optionally, it also includes a limiting part, said limiting part comprising: The mounting sleeve is fixedly connected to the machine body; A limiting pin is movably inserted into the mounting sleeve, and the end of the limiting pin is used to insert into the teeth of the gear; The first spring is sleeved on the limiting pin and located in the mounting sleeve.

[0011] Optionally, the atomizer is provided with a discharge pipe, the rotating part includes a connector, the connector is fixedly connected to the end of the connecting pipe near the rotating section, and the connector is rotatably connected to the end of the discharge pipe, and a sealing ring is provided between the connector and the discharge pipe.

[0012] Optionally, the two ends of the connector have opposing inclined surfaces, and the rotating part further includes: A rotating sleeve is rotatably fitted on the outside of the connector, and one end of the rotating sleeve is slidably connected to the discharge pipe. A convex ring is provided on the inner wall of the rotating sleeve near both ends, and the convex ring has an inclined surface adapted to the inclined surface. A drive sleeve is fixedly fitted onto the rotating drum, and the drive sleeve is fitted onto the outside of the rotating sleeve. When the drive sleeve is in a stationary state, the inclined surface of the convex ring is in contact with the inclined surface on the corresponding side, so that the connector and the discharge pipe maintain a sealed connection.

[0013] Optionally, an annular groove is formed on the outer wall of the rotating sleeve, the annular groove is wavy, a groove is formed on the inner wall of the driving sleeve, an insert block is movably disposed in the groove, the end of the insert block is located in the annular groove, and a second spring is disposed between the insert block and the bottom of the groove.

[0014] Optionally, the annular groove includes alternating crest and trough segments along the circumference. When the protrusion is located at the peak position of the crest or trough segment, the rotating sleeve is located at two extreme positions along the axis of the rotating cylinder, and the inclined surface of the protruding ring is in contact with the inclined surface.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In a multi-angle smoke jet generator provided by this invention, the rotating part drives the rotating base to rotate around the axis of the rotating drum, causing the connecting section of the connecting pipe to swing and drive the jet head to rotate, thereby adjusting the jet direction. Under the action of the rotating part, the rotating section maintains stable communication with the atomizing generator, preventing leakage or flow interruption. Through the rotating drum and rotating base, the jet head can be angled around a fixed axis, achieving rapid changes in jet direction without the need for a complete relocation of the equipment, improving ease of use. Simultaneously, by setting up the rotating section and rotating part, the connecting pipe maintains communication with the atomizing generator even when the angle changes, effectively avoiding problems such as pipe twisting, disconnection, or fluid obstruction caused by structural rotation.

[0028] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0029] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0030] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-9 As shown, this embodiment of the invention provides a multi-angle smoke jetting machine for use in scenarios where smoke is generated by atomizing media such as liquid medicine or e-liquid and sprayed onto a target area. In view of the shortcomings of existing smoke jetting machines that are difficult to adjust the spray direction while ensuring structural integration and normal spraying, this embodiment aims to provide a smoke jetting machine that can adjust the spray direction of the spray head and ensure normal spraying through structural improvements.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, the multi-angle smoke jet machine includes a body 1, an atomizing generator 2 disposed within the body 1, and a jet head 31 communicating with the atomizing generator 2. A mounting cavity 11 communicating with the outside is provided on one side of the body 1. A rotating cylinder 13 is rotatably disposed within the mounting cavity 11, and a rotating seat 3 is mounted on the rotating cylinder. The jet head 31 is disposed on the rotating seat 3, and the jet head 31 is connected to the atomizing generator 2 via a connecting pipe 4. The connecting pipe 4 includes a rotating section 41 communicating with the atomizing generator 2 and a connecting section 42 communicating with the jet head 31. The rotating section 41 is located within the rotating cylinder 13 and is coaxially arranged with the rotating cylinder 13. A rotating part 5 is provided on the body 1, which drives the rotating seat 3 to rotate around the axis of the rotating cylinder 13. The rotating section 41 is connected to the atomizing generator 2 via a rotating part 6. When the angle of the connecting section 42 of the connecting pipe 4 changes, the rotating part 6 is used to maintain communication and sealing between the rotating section 41 and the atomizing generator 2.

[0033] Specifically, the body 1 can house an atomizing medium storage tank and an atomizer 2. The atomizer 2 continuously converts the atomizing medium into smoke. One side of the body 1 has a mounting cavity 11 that communicates with the outside. The mounting cavity 11 can be a notch formed on the body 1, and its three adjacent sides communicate with the outside. A rotating cylinder 13 is rotatably mounted within the mounting cavity 11. Both ends of the rotating cylinder 13 are connected to the body 1 via bearings. A rotating seat 3 is fixedly fitted onto the outside of the rotating cylinder 13, allowing the rotating seat 3 to rotate around the axis of the rotating cylinder 13. A spray head 31 is mounted on the rotating seat 3 and rotates synchronously with it, thus changing the spray direction. The spray head 31 is connected to the atomizer 2 via a connecting pipe 4. The connecting pipe 4 includes a rotating section 41 and a connecting section 42. The rotating section 41 communicates with the atomizer 2 and is located inside the rotating cylinder 13, coaxially with it. The connecting section 42 communicates with the spray head 31 and changes angle with the rotation of the rotating seat 3.

[0034] It should be noted that the outer contour of the mounting cavity 11 can be semi-circular, and the rotating seat 3 can be set as a circular seat. The edge of the rotating seat 3 is aligned with the outer contour of the mounting cavity 11, so that when the rotating seat 3 rotates, it always stays inside the mounting cavity 11, that is, the rotating seat 3 will not protrude from the side wall of the body 1, thereby ensuring that the space occupied by the smoke jet machine will not change due to the adjustment of the spray direction of the spray head 31, and thus ensuring the integration of the smoke jet machine structure.

[0035] Meanwhile, a rotating part 5 is provided on the body 1. The rotating part 5 drives the rotating seat 3 to rotate around the axis of the rotating cylinder 13, thereby causing the spray head 31 to change the spray direction. The rotating section 41 is connected to the atomizer 2 through the rotating part 6. The rotating part 6 can maintain the connection and seal between the rotating section 41 and the atomizer 2 when the angle of the connecting section 42 changes. For example, the rotating part 6 can adopt a sealed connection structure with relative rotation capability, so that the gas passage can still be maintained and sealed when the connecting pipe 4 rotates or changes in angle. In actual operation, by operating the rotating part 5 to drive the rotating seat 3 to rotate around the axis of the rotating cylinder 13, the spray head 31 rotates accordingly, thereby realizing the adjustment of the spray direction. At the same time, the connecting section 42 of the connecting pipe 4 swings accordingly. Under the action of the rotating part 6, the rotating section 41 maintains a stable connection with the atomizer 2, avoiding leakage or flow interruption. Therefore, by using the rotating drum 13 and the rotating seat 3, the spray head 31 can be adjusted around a fixed axis, and the spray direction can be quickly changed without the need for the entire moving equipment, thus improving ease of use. At the same time, by setting the rotating section 41 and the rotating part 6, the connecting pipe 4 can still maintain communication with the atomizing generator 2 when the angle changes, effectively avoiding problems such as pipe twisting, disconnection or fluid obstruction caused by structural rotation.

[0036] Furthermore, the body 1 has an arc-shaped hole 12 that communicates with the mounting cavity 11. The rotating part 5 includes a rotating rod 14 that is fixedly connected to the rotating seat 3. The rotating rod 14 passes through the arc-shaped hole 12, and the circle of the arc-shaped hole 12 coincides with the axis of the rotating cylinder 13.

[0037] Specifically, an arc-shaped hole 12 communicating with the mounting cavity 11 is provided on the side wall of the body 1. The center of the arc-shaped hole 12 coincides with the axis of the rotating drum 13. A rotating rod 14 is fixedly connected to the rotating seat 3. The extension direction of the rotating rod 14 is parallel to the axis of the rotating drum 13. The rotating rod 14 extends outward from the rotating seat 3 and passes through the arc-shaped hole 12. An operating handle can be fixed to the end of the rotating rod 14. For example, when the operating handle is operated, the rotating rod 14 moves within the arc-shaped hole 12, thereby driving the rotating seat 3 to rotate around the axis of the rotating drum 13. In actual use, the operator can move or push the rotating rod 14 located in the arc-shaped hole 12 to make it slide along the arc-shaped hole 12, thereby driving the rotating seat 3 to rotate around the axis of the rotating drum 13, thus adjusting the spray direction of the spray head 31. The length of the arc-shaped hole 12 can be set as needed to limit the maximum rotation angle range of the spray head 31. The angle of the spray head 31 can be directly adjusted by external operation through the rotating rod 14, improving the ease of operation. In addition, the center of the arc-shaped hole 12 coincides with the axis of the rotating drum 13, so that the movement trajectory of the rotating rod 14 is consistent with the rotation trajectory of the rotating seat 3. This avoids offset or jamming from a structural perspective, improving the smoothness and reliability of the adjustment process. Moreover, the arc-shaped hole 12 not only provides guidance for the rotating rod 14, but also limits the rotation range through its arc length, thereby preventing excessive rotation and improving the safety of the device.

[0038] Furthermore, the rotating part 6 includes a rotary joint, and the end of the connecting pipe 4 near the rotating section 41 is connected to the atomizer 2 via the rotary joint.

[0039] For example, the rotating part 6 may specifically include a rotary joint. One end of the connecting pipe 4 near the rotating section 41 is connected to the atomizer 2 via the rotary joint. The rotary joint is configured as a rotatable connection structure, with one end connected to the outlet end of the atomizer 2 and the other end connected to the rotating section 41 of the connecting pipe 4. A connecting channel is formed inside the rotary joint for the passage of atomized smoke. During the rotation of the spray head 31 by the rotating seat 3, the connecting section 42 of the connecting pipe 4 changes angle accordingly, while the rotating section 41 rotates relative to the atomizer 2 at the rotary joint, thereby releasing the torsional stress generated by the rotation of the connecting pipe 4. In actual operation, when the direction of the spray head 31 is adjusted by the rotating part 5, the connecting section 42 of the connecting pipe 4 swings with the spray head 31, while the rotating section 41, under the action of the rotary joint, rotates coaxially with the rotating cylinder 13, thus achieving multi-angle adjustment without affecting gas delivery.

[0040] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in this embodiment of the invention, the rotating part 5 includes a gear 51, a half-gear ring 52, and a driving member. The gear 51 is fixedly sleeved on the outside of the rotating drum 13; the half-gear ring 52 is fixedly connected to the rotating rod 14, and the half-gear ring 52 meshes with the gear 51, with the center of the half-gear ring 52 coinciding with the axis of the rotating drum 13; the driving member is fixedly connected to the machine body 1, and the driving member is connected to the gear 51 in a transmission manner.

[0041] Specifically, gear 51 is coaxially fixedly sleeved on the outside of rotating drum 13, thus enabling it to rotate synchronously with drum 13. Half-gear ring 52 is fixedly connected to rotating rod 14, meshing with gear 51, and the center of half-gear ring 52 coincides with the axis of rotating drum 13, ensuring that half-gear ring 52 always moves around the axis of rotating drum 13 during rotation. A drive component is fixedly mounted on the machine body 1 and is connected to gear 51. The drive component can be a motor or other power mechanism to provide rotational power to gear 51, meeting the operational needs of different usage scenarios. In actual operation, when the drive component drives gear 51 to rotate, gear 51 drives rotating drum 13 to rotate synchronously, thereby driving rotating seat 3 sleeved on rotating drum 13 to rotate. Simultaneously, the meshing action of half-gear ring 52 and gear 51 causes rotating rod 14 to move along the arc-shaped hole 12 with rotating seat 3, thereby adjusting the angle of spray head 31 and achieving precise control of the rotation angle.

[0042] Furthermore, the multi-angle smoke jet machine also includes a limiting part 7, which includes a mounting sleeve 71, a limiting pin 72, and a first spring 73. The mounting sleeve 71 is fixedly connected to the machine body 1; the limiting pin 72 is movably inserted into the mounting sleeve 71, and the end of the limiting pin 72 is used to insert into the teeth of the gear 51; the first spring 73 is sleeved on the limiting pin 72 and located in the mounting sleeve 71.

[0043] Specifically, the mounting sleeve 71 is fixedly connected to the machine body 1 and is arranged adjacent to the gear 51; the limiting pin 72 is movably inserted into the mounting sleeve 71, and one end of the limiting pin 72 can extend or retract along the axial direction of the mounting sleeve 71; the first spring 73 is sleeved outside the limiting pin 72 and located inside the mounting sleeve 71, one end of the first spring 73 can be fixedly connected to the limiting pin 72, and the other end can be fixedly connected to the mounting sleeve 71 to apply an elastic restoring force to the limiting pin 72. The end of the limiting pin 72 can be inserted into the tooth gap of the gear 51 to limit the rotation of the gear 51. When the limiting pin 72 extends under the action of the first spring 73, its end is embedded between the teeth of the gear 51, thereby positioning the gear 51; when an external force is applied to the limiting pin 72 to overcome the elastic force of the first spring 73 and retract, the gear 51 can rotate freely. In actual use, when the gear 51 is rotated to a predetermined angle by the drive component, the limiting pin 72 automatically inserts between adjacent teeth under the action of the first spring 73, thereby positioning the gear 51. When it is necessary to readjust the angle of the spray head 31, external force can be applied to the limiting pin 72 to disengage it from the teeth, thus releasing the limiting position, and then the angle adjustment can continue. The limiting pin 72 can achieve stable positioning after the spray head 31 is adjusted to the predetermined angle, preventing angle deviation due to external vibration or misoperation.

[0044] like Figure 7 , Figure 8 and Figure 9 As shown in the embodiment of the present invention, the atomizer 2 is provided with a discharge pipe 21, the rotating part 6 includes a connector 61, the connector 61 is fixedly connected to the end of the connecting pipe 4 near the rotating section 41, and the connector 61 is rotatably connected to the end of the discharge pipe 21, and a sealing ring is provided between the connector 61 and the discharge pipe 21.

[0045] For example, the atomizer 2 is provided with a discharge pipe 21 for discharging the atomized smoke, and the connecting pipe 4 is connected to the discharge pipe 21; the rotating part 6 includes a connector 61, which is fixedly connected to one end of the connecting pipe 4 near the rotating section 41, and the connector 61 is rotatably connected to the end of the discharge pipe 21; so that the connecting pipe 4 can rotate relative to the atomizer 2, thereby adapting to the change in the angle of the connecting pipe 4 when the direction of the spray head 31 is adjusted.

[0046] Meanwhile, a sealing ring is provided between the connector 61 and the discharge pipe 21. The sealing ring is located between the mating parts of the two and forms a circumferential sealing contact. The sealing ring can adopt an elastic sealing structure, which can maintain a close fit when the connector 61 rotates relative to the discharge pipe 21. In actual operation, when the rotating seat 3 drives the injection head 31 to rotate, the connecting section 42 of the connecting pipe 4 changes angle accordingly, and the connector 61 rotates relative to the discharge pipe 21. The sealing ring continuously provides a sealing effect between the connector 61 and the discharge pipe 21, allowing the smoke to be smoothly delivered to the injection head 31 through the internal channel of the connector 61, while preventing leakage.

[0047] Furthermore, the two ends of the connector 61 have relatively inclined surfaces, and the rotating part 6 also includes a rotating sleeve 62 and a driving sleeve 63. The rotating sleeve 62 is rotatably sleeved on the outside of the connector 61, and one end of the rotating sleeve 62 is slidably connected to the discharge pipe 21. The inner wall of the rotating sleeve 62 is provided with a protruding ring near both ends, and the protruding ring has an inclined surface adapted to the inclined surface. The driving sleeve 63 is fixedly sleeved on the rotating drum 13, and the driving sleeve 63 is sleeved on the outside of the rotating sleeve 62. When the driving sleeve 63 is in a stationary state, the inclined surface of the protruding ring fits against the inclined surface on the corresponding side, so that the connector 61 and the discharge pipe 21 maintain a sealed connection.

[0048] Specifically, the two ends of the connector 61 are provided with opposing inclined surfaces. The rotating sleeve 62 is rotatably sleeved on the outside of the connector 61, and one end of the rotating sleeve 62 forms an axially sliding fit with the discharge pipe 21, allowing the rotating sleeve 62 to move along the axis of the rotating drum 13. A convex ring is provided on the inner wall of the rotating sleeve 62 near both ends, and the convex ring has an inclined surface structure adapted to the inclined surface of the connector 61. During the axial movement of the rotating sleeve 62, the inclined surface of the convex ring can interact with the inclined surface of the connector 61, thereby applying an axial force to the connector 61. The drive sleeve 63 is fixedly sleeved on the rotating drum 13 and located outside the rotating sleeve 62. The drive sleeve 63 is used to drive the rotating sleeve 62 to move along the axis of the rotating drum 13 during rotation.

[0049] In actual operation, when the rotating part 5 drives the rotating drum 13 to rotate, the driving sleeve 63 and the rotating sleeve 62 interact, causing the rotating sleeve 62 to displace along the axis of the rotating drum 13. When the rotating sleeve 62 moves to the preset position, the inclined surface of its inner convex ring fits against the inclined surface of the connector 61, applying axial clamping force to the connector 61, thereby forming a tight fit between the connector 61 and the discharge pipe 21, achieving enhanced sealing. When it is necessary to adjust the angle of the spray head 31, the rotating sleeve 62 disengages from the clamping position under the driving action, and the clamping state between the connector 61 and the discharge pipe 21 weakens, allowing the connector 61 to rotate relative to the discharge pipe 21; when it rotates to the target angle, the rotating sleeve 62 moves back to the clamping position, achieving seal restoration. The axial clamping force formed by the inclined surface cooperation makes the connector 61 and the discharge pipe 21 form a surface contact clamping, which is more stable and reliable than a simple sealing ring structure, and is especially suitable for easily leaking media such as smoke. By setting the rotating sleeve 62 to move axially and using the inclined surface to achieve clamping, the connection structure is in a relatively relaxed state during the adjustment process, thereby reducing rotational resistance; after the adjustment is completed, the connector 61 and the discharge pipe 21 are tightly fitted by axial clamping, thereby improving the sealing performance.

[0050] Understandably, compared to rotary joints, the connection structure has relative rotation capability during rotation adjustment through the cooperation of connector 61, rotating sleeve 62 and drive sleeve 63. At the same time, after reaching the preset angle position, the sealing surface is tightly fitted by axial compression, thereby forming a transition from dynamic seal to static seal. It can form a stable compression seal in the non-adjustment state, improve sealing reliability and reduce wear, and is especially suitable for smoke media transportation scenarios.

[0051] In this embodiment of the invention, an annular groove 621 is formed on the outer wall of the rotating sleeve 62. The annular groove 621 is wavy, and a protrusion is provided on the inner wall of the driving sleeve 63, with the protrusion located in the annular groove 621. For example, the annular groove 621 is located on the outer wall of the rotating sleeve 62 and extends circumferentially along the rotating sleeve 62, forming a continuously undulating wavy structure. A groove is formed on the inner wall of the driving sleeve 63, and an insert 64 is movably disposed in the groove. The insert 64 can reciprocate along the depth direction of the groove. One end of the insert 64 extends out of the groove and inserts into the annular groove 621, forming a mating relationship with the annular groove 621. A second spring 65 is provided between the insert 64 and the bottom of the groove. The second spring 65 is used to push the insert 64 outward so that its end always remains in contact with the annular groove 621.

[0052] During the rotation of the drum 13, the drive sleeve 63 rotates accordingly, and the insert block 64 moves along the wavy path of the annular groove 621 under its guidance, thereby driving the rotating sleeve 62 to displace along the axis of the drum 13. Simultaneously, due to the axial undulations of the annular groove 621, the insert block 64 is subjected to radial compression and release during movement, causing the second spring 65 to compress or extend accordingly to adapt to the shape changes of the annular groove 621. Thus, the rotational motion of the drum 13 can be converted into the axial reciprocating motion of the rotating sleeve 62, thereby achieving linkage between rotational adjustment and axial clamping.

[0053] For example, the annular groove 621 includes crest sections and trough sections that are alternately arranged in the circumferential direction. When the protrusion is located at the peak position of the crest section or the trough section, the rotating sleeve 62 is located at two extreme positions in the direction of the axis of the rotating cylinder 13, and the inclined surface of the protruding ring is in contact with the inclined surface.

[0054] The annular groove 621 includes alternating crest and trough sections along its circumference, with each crest and trough corresponding to a different height position in the axial direction. The end of the insert 64 remains in contact with the inner wall of the annular groove 621 under the action of the second spring 65 and can move along the extending direction of the annular groove 621. When the rotating cylinder 13 drives the drive sleeve 63 to rotate, the insert 64 moves along a wave path in the annular groove 621, thereby driving the rotating sleeve 62 to displace along the axial direction of the rotating cylinder 13.

[0055] When the rotating drum 13 rotates to a predetermined angle and stops, under the elastic action of the second spring 65, the insert block 64 pushes the rotating sleeve 62 to continue rotating slightly, so that the end of the insert block 64 eventually stabilizes at the peak position of the crest or trough section. When the insert block 64 is at the peak position of the crest section, the rotating sleeve 62 is at one extreme position along the axis of the rotating drum 13; when the insert block 64 is at the trough position of the trough section, the rotating sleeve 62 is at the other extreme position along the axis of the rotating drum 13. In both extreme position states, the inclined surface of the inner convex ring of the rotating sleeve 62 keeps in contact with the inclined surface of the corresponding end of the connector 61, thereby applying an axial clamping force to the connector 61, so that a stable sealed connection is formed between the connector 61 and the discharge pipe 21.
