Description

Technical Field

[0001] This application relates to the field of tobacco technology, and in particular to cleaning devices and tobacco pack gathering devices. Background Technology

[0002] The YJ27 assembly machine's forming system mainly consists of a closing drum, a joining drum, a rubbing plate, a conveying drum, and a cutting drum. The closing drum completes the alignment and tipping of the cigarette packs, the joining drum completes the joining process, the conveying drum completes the conveying of double-length filter cigarettes, and the cutting drum completes the final cutting and waste removal of the filter cigarettes.

[0003] In related technologies, the cross-flow of air from the intake and cleaning air from the drum's orifices on the approach drum creates a turbulent airflow field. The junction between the approach drum and the joining drum restricts the movement space of tobacco shreds and dust, causing them to collide with equipment components and resulting in multi-directional and irregular movement. When the cigarette, tipping paper, and filter enter the joining system, some tobacco dust flies into the area where the tipping paper and the cigarette assembly meet. There is a high probability that the tobacco dust will adhere to the already glued tipping paper, forming tobacco dust-laden cigarettes. Larger tobacco dust-laden cigarettes can also lead to poor joining and wrinkling defects in the tipping paper. A blowing block can be added to one axial side of the approach drum to remove tobacco dust and shreds from it.

[0004] However, the cleaning effect of the aforementioned blower block on tobacco dust and shredded tobacco needs improvement. Utility Model Content

[0005] Therefore, it is necessary to provide a cleaning device and a tobacco gathering device that can improve the cleaning effect of the blower on the tobacco dust and tobacco shreds on the gathering drum.

[0006] In a first aspect, embodiments of this application provide a cleaning device for a smoke assembly gathering device, the smoke assembly gathering device including a gathering drum and two float rings, the two float rings being located on both sides of the axial direction of the gathering drum;

[0007] The cleaning device includes:

[0008] An adjusting rod is located on the radial side of the approaching drum and extends along the axial direction of the approaching drum. The two ends of the adjusting rod are connected to two floats respectively. A first gas passage is provided in the adjusting rod. The adjusting rod has a first air inlet and a first air outlet that are connected to the first gas passage. The first air inlet is used to connect to a gas source.

[0009] A blower is sleeved on the outer periphery of the adjusting rod. The blower has a second gas channel and a second air inlet, a second air outlet, and a third air outlet that are connected to the second gas channel. The second air inlet is connected to the first air outlet. The air outlet of the second air outlet is directed from the center of the drum to one end of the drum. The air outlet of the third air outlet is directed from the center of the drum to the other end of the drum.

[0010] The cleaning device provided in this application embodiment allows the gas supplied by the gas source to sequentially pass through a first air inlet, a first gas channel, a first air outlet, a second air inlet, and a second gas channel to reach a second air outlet and a third air outlet. The gas is then blown from the center of the approach drum towards both ends of the approach drum through the second and third air outlets, respectively. This shortens the cleaning path of both airflows along the axial direction of the approach drum when cleaning the soot, thereby enhancing the cleaning ability of the two airflows and improving the cleaning ability of the blower on scattered soot, thus reducing the amount of soot trapped in the soot.

[0011] In one embodiment, there are multiple second air outlets and multiple third air outlets, and the multiple second air outlets and multiple third air outlets are arranged correspondingly.

The two cigarette bearing surfaces are located on both sides of the filter tip bearing surface along the axial direction of the adjoining drum, and the arc-shaped channel wall is opposite to and spaced apart from the filter tip bearing surface along the radial direction of the adjoining drum.

[0018] The dimension of the arc-shaped channel wall along the axial direction of the drum is greater than the dimension of the filter nozzle bearing surface along the axial direction of the drum.

[0019] In one embodiment, the opening area of ​​the first air outlet gradually increases from the radial center of the adjusting rod to its edge; and / or,

[0020] The first air outlet is located at the middle of the extension direction of the adjusting rod; and / or,

[0021] The first air inlet is located on the end face of one end of the adjusting rod; and / or,

[0022] The blower is positioned close to the axial center of the drum.

[0023] In one embodiment, the adjusting rod includes a first sub-adjusting rod and a second sub-adjusting rod, which are arranged along the extending direction of the adjusting rod. A first gas passage extends through the first sub-adjusting rod and a portion of the second sub-adjusting rod along the extending direction of the adjusting rod. A first air inlet is located on the end face of the first sub-adjusting rod opposite to the end of the second sub-adjusting rod. A first air outlet extends through the outer peripheral surface of the second sub-adjusting rod near the end of the first sub-adjusting rod. A portion of the first sub-adjusting rod is inserted into the second sub-adjusting rod and is threadedly connected to the second sub-adjusting rod; and / or,

[0024] A limiting protrusion is provided on the outer circumferential surface of the adjusting rod, with one end of the limiting protrusion located near the first air inlet. The size of the limiting protrusion is greater than or equal to the size of the first gas channel along the extension direction of the adjusting rod. A limiting groove is provided on the surface of the blower facing the adjusting rod, and the limiting groove extends through the blower along the extension direction of the adjusting rod. The limiting groove includes a first groove side and a second groove side spaced apart along the circumference of the adjusting rod. Part of the limiting protrusion is located in the limiting groove and abuts against the first groove side and the second groove side. The distance between the first groove side and the second groove side along the circumference of the adjusting rod and the size of the limiting protrusion along the circumference of the adjusting rod gradually increase from the first air inlet to the first air outlet.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms 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 this application 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 this application.

[0035] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0038] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0039] In related technologies, the cross-flow of air from the intake and cleaning air from the drum's orifices on the approach drum creates a turbulent airflow field. The junction between the approach drum and the joining drum restricts the movement space of tobacco shreds and dust, causing them to collide with equipment components and resulting in multi-directional and irregular movement. When the cigarette, tipping paper, and filter enter the joining system, some tobacco dust flies into the area where the tipping paper and the cigarette assembly meet. There is a high probability that the tobacco dust will adhere to the already glued tipping paper, forming tobacco dust-laden cigarettes. Larger tobacco dust-laden cigarettes can also lead to poor joining and wrinkling defects in the tipping paper. A blowing block can be added to one axial side of the approach drum to remove tobacco dust and shreds from it.

[0040] However, when the blower block is positioned on the axial side of the drum, and the blowing direction of the blower block is from one end of the axial direction of the drum to the other, the blower block only provides an outward axial blowing. When the airflow cleans the drum, it needs to travel from one end of the axial direction of the drum to the other. The cleaning path of the airflow is relatively long, resulting in poor cleaning effect of the blower block on scattered tobacco shreds and tobacco dust, and poor improvement effect on the dust-laden tobacco.

[0041] To address the aforementioned issues, embodiments of this application provide a cleaning device and a smoke assembly gathering device, which can improve the cleaning effect of the blower on smoke dust, tobacco shreds, etc., on the gathering drum.

[0042] The following will combine Figures 1-5 The cleaning device and smoke gathering device provided in the embodiments of this application will be described.

[0043] This application provides a tobacco assembly gathering device, which includes a gathering drum, two floats, and a cleaning device 100 as described in the following embodiments. The two floats are located on both sides of the axial direction X of the gathering drum, and are respectively connected to the two ends of the adjusting rod 110 of the cleaning device 100. The cleaning device 100 can be used to clean tobacco shreds, tobacco dust, paper scraps, etc. on the gathering drum (this application uses tobacco dust as an example for illustration).

[0044] For example, a cigarette pack may include a filter tip twice the length of the filter tip and two cigarette sticks once the length of the filter tip, with the two cigarette sticks located on both sides of the filter tip and connected to the filter tip by tipping paper.

[0045] For example, the smoke assembly convergence device can be applied to the YJ27 assembly machine.

[0046] In some embodiments, the position of the adjusting rod 110 relative to the approach drum can be fixed. The two floats can tightly bring the two sections of the cigarette and the filter together, eliminating the axial X-gap between the cigarette and the filter.

[0047] For example, the float rings can be movably configured along the extension direction of the adjusting rod 110, and the float rings are movably connected to the adjusting rod 110. The spacing between the two float rings can be adjusted by adjusting the positions of the two float rings relative to the adjusting rod 110. Alternatively, the float rings and the adjusting rod 110 can also be fixedly connected. This application embodiment does not limit this.

[0048] In some embodiments, the outer peripheral surface of the adducting drum includes a filter tip bearing surface and two cigarette bearing surfaces. The two cigarette bearing surfaces are located on opposite sides of the filter tip bearing surface along the axial direction X of the adducting drum. The filter tip bearing surface supports the filter tip, and the cigarette bearing surfaces support the cigarettes. The filter tip bearing surface and the cigarette bearing surface can be recessed to form a groove, which is used to limit the movement of the cigarette assembly. During operation, two cigarette sections and one filter tip are placed in the groove, with the filter tip positioned between the two cigarette sections. The filter tip and the cigarettes can be held in place by the negative pressure provided by the negative pressure suction hole at the bottom of the groove.

[0049] The cleaning device 100 provided in the embodiments of this application will be described below.

[0050] See Figure 1 , Figure 3 and Figure 5 This application provides a cleaning device 100 for cleaning tobacco residue on a drum. The cleaning device 100 includes an adjusting rod 110 and a blowing component 120. The adjusting rod 110 is located on one radial side of the drum and extends along the axial direction X of the drum. The axial direction of the adjusting rod 110 and the axial direction X of the drum can be parallel, and the extension direction of the adjusting rod 110 is also its axial direction. Both ends of the adjusting rod 110 are connected to two float rings. A first gas channel 1111 is provided in the adjusting rod 110. The adjusting rod 110 has a first air inlet 1121 and a first air outlet 1131 communicating with the first gas channel 1111. The first air inlet 1121 is used to communicate with a gas source. The gas source provides gas for cleaning the tobacco residue. A blower 120 is sleeved on the outer periphery of an adjusting rod 110, which passes through a through hole 127. The blower 120 is positioned at a first air outlet 1131 and includes a second gas channel 1242. The blower 120 has a second air inlet, a second air outlet 1262, and a third air outlet 1263, all communicating with the second gas channel 1242. The second air inlet is connected to the first air outlet 1131 and is located on the side of the blower 120 facing the through hole 127. The second air outlet 1262 discharges air from the center of the drum to one end of the drum, and the third air outlet 1263 discharges air from the center of the drum to the other end of the drum.

[0051] The gas supplied by the gas source can sequentially pass through the first air inlet 1121, the first gas channel 1111, the first air outlet 1131, the second air inlet, and the second gas channel 1242 to reach the second air outlet 1262 and the third air outlet 1263. The gas is then blown from the center of the approach drum towards both ends of the approach drum through the second air outlet 1262 and the third air outlet 1263, respectively. This shortens the cleaning path of both airflows along the axial direction X of the approach drum when cleaning the soot, thereby improving the cleaning ability of the two airflows and enhancing the cleaning ability of the blower 120 on the scattered soot, thus reducing the amount of soot trapped (for example, the quality defect of soot trapped can be reduced by 68%).

[0052] It should be noted that since the two float rings are connected by the adjusting rod 110, and the adjusting rod 110 is also used as an air intake channel, there is no need to set up a separate air intake channel and an adjusting rod 110 to connect the float rings. That is, the adjusting rod 110 integrates multiple functions, which helps to simplify the structure of the cleaning device 100 and reduce the manufacturing cost.

[0053] For example, after passing through the second air outlet 1262, the airflow forms a first airflow, which flows from the axial X-center of the approaching drum to one end. After passing through the third air outlet 1263, the airflow forms a second airflow, which flows from the axial X-center of the approaching drum to the other end. The two airflows, namely the first airflow and the second airflow, blow air from the center of the approaching drum towards both ends of the approaching drum for cleaning.

[0054] For example, when the tobacco assembly gathering device is activated, the cleaning device 100 blows air to form a first airflow and a second airflow. The airflow direction of the first and second airflows is from the filter of the tobacco assembly on the gathering drum to the tobacco sticks on both sides, carrying the tobacco dust out into the waste bin. The blowing continues during the operation of the tobacco assembly gathering device. When the tobacco assembly gathering device stops operating, the blowing can be stopped.

[0055] For example, the blower 120 can be positioned close to the axial X-center of the adjoining drum, so that the lengths of the cleaning paths of the first airflow and the second airflow through the axial direction of the adjoining drum are relatively consistent, which is beneficial to improving the uniformity of cleaning the soot on the adjoining drum.

[0056] In some embodiments, see Figure 5There are multiple second air outlets 1262, which makes the airflow direction of the first airflow provided by a single second air outlet 1262 more precise and concentrated. Similarly, there are multiple third air outlets 1263, which makes the airflow direction of the second airflow provided by a single third air outlet 1263 more precise and concentrated. The multiple second air outlets 1262 and the multiple third air outlets 1263 are correspondingly arranged, with the second air outlets 1262 and the corresponding third air outlets 1263 facing each other and spaced apart along the axial direction X of the drum. This improves the uniformity of the airflow provided by the multiple second air outlets 1262 and the multiple third air outlets 1263.

[0057] In some embodiments, a plurality of second air outlets 1262 are arranged at intervals along the circumference of the approach drum, thereby enabling the plurality of second air outlets 1262 to provide a relatively uniform first airflow in the circumference of the approach drum.

[0058] In some embodiments, a plurality of third air outlets 1263 are arranged at intervals along the circumference of the approach drum, thereby enabling the plurality of third air outlets 1263 to provide a relatively uniform second airflow in the circumference of the approach drum.

[0059] In some embodiments, see Figure 5 The blower 120 includes a first channel wall 121 and a second channel wall 122. The first channel wall 121 and the second channel wall 122 are arranged opposite to each other along the axial direction X of the drum and are spaced apart. The second air outlet 1262 is located in the first channel wall 121 and the third air outlet 1263 is located in the second channel wall 122.

[0060] In some embodiments, see Figure 1 The blower 120 includes an arc-shaped channel wall 123 facing the side of the drum. The arc-shaped channel wall 123 is connected to the first channel wall 121 and the second channel wall 122. The surface of the arc-shaped channel wall 123 facing the side of the drum is a first arc surface. The first arc surface is concentrically arranged with the drum. This makes the distance between the first arc surface and the drum closer, which is beneficial to improving the cleaning ability of the blower 120 to remove soot and reducing the space occupied by the cleaning device 100. In addition, it is also beneficial to improve the uniformity of the blowing of the blower 120 along the circumference of the drum.

[0061] In some embodiments, see Figure 1 The first channel wall 121 has a first end and a second end at its two ends along the circumference of the drum. The distance between the first end and the adjusting rod 110 is smaller than the distance between the second end and the adjusting rod 110. In this way, the air blowing component 120 between the first end and the adjusting rod 110 obstructs the drum less, which is beneficial for observing the drum at the first end. In addition, the air blowing component 120 between the second end and the adjusting rod 110 can be set directly opposite to more of the outer circumferential surfaces of the drum, which is beneficial for setting more second air outlets 1262 and improving the blowing effect.

[0062] In some embodiments, the first end is closer to the adjusting rod 110, making the second air outlet 1262 near the first end closer to the air source, and the second end is closer to the adjusting rod 110, making the second air outlet 1262 near the second end farther from the air source. The opening area of ​​the multiple second air outlets 1262 is increased sequentially from the first end to the second end. In this way, the inconsistent air output caused by the different distances between the air source and the second air outlets 1262 can be balanced, which is beneficial to improving the uniformity of air output from each second air outlet 1262.

[0063] In other embodiments, the opening area of ​​each second air outlet 1262 can be the same, thereby reducing the design difficulty of each second air outlet 1262.

[0064] In some embodiments, see Figure 1 The second channel wall 122 has a third end and a fourth end at its two ends along the circumference of the drum. The distance between the third end and the adjusting rod 110 is smaller than the distance between the fourth end and the adjusting rod 110. In this way, the air blowing component 120 between the third end and the adjusting rod 110 obstructs the drum less, which is beneficial for observing the drum at the third end. In addition, the air blowing component 120 between the fourth end and the adjusting rod 110 can be set directly opposite to more of the outer circumferential surfaces of the drum, which is beneficial for setting more third air outlets 1263 and improving the blowing effect.

[0065] In some embodiments, the third end is closer to the adjusting rod 110, and the third air outlet 1263 near the third end is closer to the air source. The fourth end is closer to the adjusting rod 110, and the third air outlet 1263 near the fourth end is farther from the air source. The opening area of ​​the multiple third air outlets 1263 is increased sequentially from the third end to the fourth end. In this way, the inconsistent air output caused by the different distances between the air source and the third air outlet 1263 can be balanced, which is beneficial to improving the uniformity of air output from each third air outlet 1263.

[0066] In other embodiments, the opening area of ​​each third air outlet 1263 can be the same, thereby reducing the design difficulty of each third air outlet 1263.

[0067] In some embodiments, the arc-shaped channel wall 123 and the filter tip bearing surface of the approach drum are arranged radially opposite to and spaced apart from each other. In some examples, the dimension of the arc-shaped channel wall 123 along the axial direction X of the approach drum is larger than the dimension of the filter tip bearing surface along the axial direction X of the approach drum. This provides better shielding of the filter tip bearing surface by the arc-shaped channel wall 123 along the axial direction X of the approach drum, preventing external tobacco dust from contacting the tipping paper. In other examples, the dimension of the arc-shaped channel wall 123 along the axial direction X of the approach drum can be smaller than or equal to the dimension of the filter tip bearing surface along the axial direction X of the approach drum.

[0068] In some embodiments, see Figure 2 The opening area of ​​the first air outlet 1131 gradually increases from the radial center to the edge of the adjusting rod 110, which facilitates the diffusion of airflow from the first gas channel 1111 to the second gas channel 1242.

[0069] In some embodiments, the first air outlet 1131 is located in the middle of the extension direction of the adjusting rod 110. In this case, the blower 120 is set close to the middle of the extension direction of the adjusting rod 110, which is conducive to setting the blower 120 close to the axial X center of the approach drum. In this way, the length of the cleaning path of the first airflow and the second airflow through the approach drum is more consistent, which is conducive to improving the cleaning uniformity of the smoke on the approach drum.

[0070] In some embodiments, see Figure 2 and Figure 3 The first air inlet 1121 is located on the end face of one end of the adjusting rod 110, so that the first air inlet 1121 can be easily connected to the connector 130, thereby facilitating the supply of gas to the adjusting rod 110.

[0071] For example, connector 130 and adjusting rod 110 can be threaded together.

[0072] For example, the air source can be the original air source, so there is no need to set up an external air source separately for the cleaning device 100.

[0073] For example, at least one of the adjusting rod 110 and the blower 120 may be made of metal, such as steel.

[0074] For example, the dimension of the adjusting rod 110 along the extension direction can be 350 mm.

[0075] For example, the first air outlet 1131 has a dimension of 16 mm along the extension direction of the adjusting rod 110.

[0076] For example, the dimension of the blower 120 along the extension direction of the adjusting rod 110 can be 40 mm.

[0077] In some embodiments, the blower 120 can be fixed to the adjusting rod 110 with fastening screws, making it easy and quick to install and remove the blower 120 and the adjusting rod 110.

[0078] In some embodiments, see Figure 2The adjusting rod 110 includes a first sub-adjusting rod 110a and a second sub-adjusting rod 110b. The first sub-adjusting rod 110a and the second sub-adjusting rod 110b are arranged along the extension direction of the adjusting rod 110. The first gas channel 1111 passes through the first sub-adjusting rod 110a and part of the second sub-adjusting rod 110b along the extension direction of the adjusting rod 110. The first gas channel 1111 can be prepared in the first sub-adjusting rod 110a and part of the second sub-adjusting rod 110b in two separate preparations, which can reduce the length of the first gas channel 1111 prepared in a single preparation and reduce the difficulty of preparing the first gas channel 1111. The first air inlet 1121 is located on the end face of the first sub-adjusting rod 110a away from the second sub-adjusting rod 110b. The first air outlet 1131 penetrates the outer peripheral surface of the second sub-adjusting rod 110b near the end of the first sub-adjusting rod 110a. Part of the first sub-adjusting rod 110a is inserted into the second sub-adjusting rod 110b, and the first sub-adjusting rod 110a and the second sub-adjusting rod 110b are threadedly connected. In this way, the first sub-adjusting rod 110a or the second sub-adjusting rod 110b can be replaced separately, which helps to reduce maintenance costs.

[0079] In some embodiments, see Figure 3 and Figure 4 The absence of a first gas channel 1111 in some second sub-adjusting rods 110b can improve the mechanical strength of the second sub-adjusting rods 110b and help extend their service life.

[0080] In some embodiments, a limiting protrusion is provided on the outer peripheral surface of the adjusting rod 110. One end of the limiting protrusion is located near the first air inlet 1121. Along the extending direction of the adjusting rod 110, the size of the limiting protrusion is greater than or equal to the size of the first gas channel 1111. The limiting protrusion helps to increase the structural strength of the adjusting rod 110 with the first gas channel 1111. A limiting through groove is provided on the surface of the blower 120 facing the adjusting rod 110. The limiting through groove extends along the extending direction of the adjusting rod 110 and can penetrate the blower 120 along the extending direction of the adjusting rod 110. The limiting through groove communicates with the through hole 127, and the opening of the limiting through groove can be located on the inner surface of the through hole 127. The limiting groove includes a first groove side and a second groove side spaced apart along the circumference of the adjusting rod 110. When the adjusting rod 110 and the blower 120 are in the assembled state, a portion of the limiting protrusion is located in the limiting groove, and the limiting protrusion abuts against the first groove side and the second groove side. Either the distance between the first groove side and the second groove side along the circumference of the adjusting rod 110 and the dimension of the limiting protrusion along the circumference of the adjusting rod 110 gradually increases from the first air inlet 1121 to the first air outlet 1131. With this configuration, during the assembly of the adjusting rod 110 and the blower 120, one end of the adjusting rod 110 with the first air inlet 1121 can be inserted into the through hole 127 of the blower 120. Simultaneously, by observing the relative arrangement of the limiting protrusion and the limiting through groove along the axial direction X of the adjusting rod 110, the limiting protrusion and the limiting through groove are aligned, allowing the limiting protrusion to insert into the limiting through groove. This pre-positions the circumferential relative position of the blower 120 and the adjusting rod 110. Furthermore, the distance between the side of the first groove and the side of the second groove along the circumference of the adjusting rod 110 extends from the first air inlet 1121 to the first... The direction of the air outlet 1131 gradually increases, and the dimension of the limiting protrusion along the circumference of the adjusting rod 110 gradually increases from the first air inlet 1121 to the first air outlet 1131. When the assembly is in place, this gradual dimension setting can prevent the adjusting rod 110 and the blower 120 from moving beyond the preset position along the axial direction X, thereby positioning the relative position of the blower 120 and the adjusting rod 110 along the axial direction X. This can prevent the first air outlet 1131 and the second air inlet from being misaligned, reducing the difficulty of aligning the first air outlet 1131 and the second air inlet.

[0081] In some embodiments, on the blower 120, the limiting slot may be offset from the second air inlet circumferentially along the through hole 127. On the adjusting rod 110, the limiting protrusion and the first air outlet 1131 may be offset circumferentially along the adjusting rod 110.

[0082] In some embodiments, the end face of the limiting protrusion may be flush with the end face of the first air inlet 1121 of the adjusting rod 110.

[0083] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
