Description

Technical Field

[0001] This utility model relates to a spraying device. Background Technology

[0002] Previously, sprayers with both liquid and gas nozzles were known, spraying both liquid and gas together. Such sprayers have a liquid container that holds liquids such as lotions. In such containers, a part is installed to seal the opening to prevent leakage if spilled. This part can interfere with the user's ability to refill the container, resulting in a poor user experience. Utility Model Content

[0003] This invention was made in view of the above circumstances, and its purpose is to provide a spraying device that can conveniently fill a container with new liquid.

[0004] The spraying device of this utility model comprises: a housing body having a gas canister; a sprayer having a liquid nozzle and a gas nozzle, and spraying liquid and gas together; and a container body having an opening and containing the liquid inside. The sprayer has a handle having a locking part. When the sprayer is placed on the housing body by locking the locking part to the locking part provided on the housing body, the handle is located on the side of the housing body. The container body has a bottomed cylindrical body and a neck connected to the upper end of the body, and the neck can be connected to the sprayer. When the container body is separated from the sprayer, the opening is open.

[0005] With this structure, users can easily refill the liquid through the opening. Therefore, users can reuse the liquid container, saving on the cost of using a spray device compared to replacing the container every time it's used up, as they can simply purchase the liquid in its standard packaging without having to buy new containers.

[0006] Furthermore, after the liquid in the container is used up, the user can refill it with a different type of liquid. Therefore, the practicality of the spray device can be improved.

[0007] In the above-mentioned spraying device, preferably, the housing body is composed of an upper housing and a lower housing, and the locking part is disposed on the upper housing.

[0008] With this structure, the sprayer can be mounted on the upper housing, making it easier to load and unload the liquid container without first removing the sprayer, compared to when the sprayer is mounted on the lower housing. This improves the convenience of the spraying device.

[0009] In the above-mentioned spraying device, preferably, the locking part is provided on the upper surface of the upper housing.

[0010] This structure further improves the convenience of the spraying device.

[0011] In the above-described spraying device, preferably, the sprayer has a cover portion having a connecting portion and a cap-shaped outer portion covering the connecting portion from the outside. The connecting portion has a mounting portion for mounting the container body. The mounting portion has a top plate portion and a side plate portion hanging down from the periphery of the top plate portion. When the container body is mounted on the sprayer, the top plate portion is located above the opening portion, and an outer air hole is formed in the top plate portion to communicate between the inside of the container body and the outside of the sprayer.

[0012] With this structure, when the atomizer sprays liquid and gas together, external air can flow into the interior of the container body. Therefore, a sufficient amount of liquid can be sprayed from the atomizer.

[0013] In the above-described spraying device, preferably, a cylindrical portion is provided on the lower surface of the top plate portion for a tube to be inserted for drawing liquid from the container body. A disc-shaped adjusting portion is also provided on the cover portion, the adjusting portion having a through hole through which the cylindrical portion passes. The adjusting portion is in airtight contact with the cylindrical portion via the through hole and is rotatable around the cylindrical portion. A slit is formed on the side plate portion, and the adjusting portion has a protrusion extending radially outward through the slit to the space between the side plate portion and the outer casing portion. An adjusting hole is formed through the adjusting portion, the adjusting hole being configured to coincide with the outer air hole when the adjusting portion rotates around the cylindrical portion.

[0014] Based on this structure, the area of ​​the airflow path formed by the outer air holes can be adjusted through a simple design. Therefore, the user can appropriately adjust the amount of air entering the container body during spraying according to the viscosity of the liquid added to the container, thereby enabling the spraying of an appropriate amount of liquid and optimizing the spray volume from the sprayer.

[0015] In the above-mentioned spraying device, it is preferable that an operation window is provided on the outer part, and the operation window is located on the radially outer side of the protrusion and can expose the protrusion to the radially outer side.

[0016] Based on this structure, the adjustment unit can be adjusted through simple structural operation.

[0017] In the above-described spraying device, preferably, a frame-shaped guide portion is installed on the outer casing, which is fixed to the inner wall of the outer casing in a manner that surrounds the operating window. A cover component is installed on the guide portion, which is sized to cover the operating window. The cover component includes a main body and an operating portion. The main body has a shape that protrudes radially outward in a manner consistent with the curvature of the outer casing. The operating portion is disposed above the main body and protrudes radially outward from the main body. The side edge of the main body engages between the guide portion and the inner wall of the outer casing, so that the main body can slide along the guide portion.

[0018] This structure allows for the opening and closing of the control window with a simple design, ensuring ease of use of the spray device while maintaining the aesthetic appeal of the cover.

[0019] In the above-described spraying device, it is preferable to further include a cover component, which is formed by cutting off a portion of the outer casing. The cut obtained by cutting off the portion of the outer casing is the operation window. An annular portion coaxial with the outer casing is provided on the inner wall of the outer casing. An opening is provided on the annular portion facing the cover component. Groove-shaped engaging portions extending in the vertical direction are formed on both sides of the opening in the circumferential direction. A sheet-like engaging portion extending in the vertical direction is engaged by the engaging portion and is installed on the inner wall of the cover component. A protrusion protruding radially inward is formed at the lower end of the engaging portion.

[0020] This structure allows for easy opening and closing of the control window, maintaining the aesthetic appeal of the cover while ensuring the ease of use of the spray device. Furthermore, since the cover component is formed by cutting off a portion of the outer casing, the outer casing appears as a single unit when the control window is closed, further enhancing the cover's aesthetics.

[0021] In the above-mentioned spraying device, preferably, the outer air hole and the adjustment hole are provided in multiples, and the number is the same.

[0022] This structure allows for more effective control of the area of ​​the airflow path formed by the outer air holes, further improving the ease of use of the spray device.

[0023] In the above-described spraying device, preferably, the container body is connected to the sprayer via a thread provided on the outer peripheral surface of the neck.

[0024] This structure allows for convenient and reliable connection between the container body and the sprayer. Attached Figure Description

[0048] <First Implementation Method>

[0049] The following is for reference Figures 1-4 The first embodiment that embodies this utility model will be described below. Hereinafter, in each structural component, Figure 2 The upper side is taken as the top, and the lower side is taken as the bottom. Additionally, Figure 2 The left side is considered the front, and the right side is considered the back. The direction perpendicular to the up / down and front / back directions is considered the left / right direction. Figure 3 The left and right directions are used for explanation. In each figure, the front-back direction is taken as the X-axis, the left-right direction as the Y-axis, and the up-down direction as the Z-axis to represent the XYZ axes.

[0050] In this embodiment, the liquid container 10 is as follows: Figure 1 and Figure 2 The container shown is connected to the sprayer 50. The liquid container 10 is filled with a cosmetic material (not shown), such as a lotion or gel. The sprayer 50 has a liquid nozzle 51 and a gas nozzle 53, and sprays both liquid and gas together (see reference). Figure 4 The sprayer 50 is connected via a pipe T to the housing body 80 containing a gas canister B filled with gas. The pipe T forms part of the gas passage connecting the gas canister B to the gas nozzle 53.

[0051] The liquid can be a thixotropic gel composition that, upon spraying, breaks down into a mist due to shear force and then quickly reverts to its original gel state. By using such a gel composition, the viscosity of the liquid blown onto the application point (such as the user's skin) increases rapidly, making dripping difficult. Furthermore, even if the liquid container 10 is tilted and the viscosity momentarily decreases due to the impact, the viscosity quickly increases again when contained within the liquid container 10, thus preventing liquid leakage. The viscosity of the liquid can be adjusted, for example, by appropriately selecting the type and amount of thickener added to the liquid.

[0052] Carbon dioxide is the preferred gas for application. Carbon dioxide promotes blood circulation; therefore, by contacting the skin with dissolved carbon dioxide, it enhances blood circulation, positively impacting beauty and health. Furthermore, carbon dioxide is readily soluble in water and oil, allowing it to penetrate the skin and be absorbed into the bloodstream when blown onto the skin along with the liquid. When absorbed, oxygen is released from hemoglobin, supplying oxygen to cells and stimulating metabolic activity. Therefore, applying a liquid containing dissolved carbon dioxide to the skin yields superior cosmetic results.

[0053] In this embodiment, the spraying device M is configured such that when the liquid in the liquid container 10 connected to the sprayer 50 is used up, the used liquid container 10 can be removed and the liquid can be refilled into the liquid container 10.

[0054] like Figure 4 As shown, the container body 20 has an opening 21 and contains liquid inside. Specifically, the container body 20 has a bottomed cylindrical body 27 and a cylindrical neck 28 connected to the upper end of the body 27 via a shoulder. The liquid is primarily contained within the body 27. The neck 28 has a smaller diameter than the body 27 and forms an upward-opening opening 21. The opening end face 22 of the opening 21 is annular. Threads are provided on the outer peripheral surface of the neck 28, allowing it to thread into the sprayer 50. Figure 1 , 2 As shown, the outer peripheral surface of the torso 27 is a smooth surface.

[0055] like Figure 4 As shown, the sprayer 50 includes a cover 60 for easy attachment and detachment of the liquid container 10. The cover 60 is a component that allows the liquid container 10 to be reused when liquid is replenished. The cover 60 includes a connecting portion 61 and an outer fitting portion 69 that covers the connecting portion 61 from the outside.

[0056] The connecting portion 61 is connected to the container body 20, thereby communicating the liquid nozzle 51 with the interior of the container body 20. Specifically, the connecting portion 61 has a mounting portion 62 for mounting the container body 20, a nozzle holding portion 65 for holding the liquid nozzle 51, and a cylindrical portion 66. One end of a tube 67 is pressed into the cylindrical portion 66. The tube 67 communicates with the liquid nozzle 51 to form part of a flow path for liquid flow. With the tube 67 pressed into the cylindrical portion 66, the tube 67 and the cylindrical portion 66 are liquid-tightly connected to form a flow path. The tube 67 hangs down to near the bottom surface of the container body 20. A suction port for drawing liquid into the container body 20 is formed at the other end of the tube 67. The connecting portion 61 constitutes a relay flow path that supplies liquid flowing from the flow path of the tube 67 to the liquid nozzle 51 held in the nozzle holding portion 65. In addition, an outer air hole 68 is formed in the connecting portion 61. The outer air hole 68 communicates the interior of the container body 20 with the exterior of the sprayer 50.

[0057] The mounting section 62 includes a top plate section 63 and a side plate section 64. The top plate section 63 is circular in top view and closes the opening 21 from above. A through hole 63A is formed in the top plate section 63 to connect the nozzle holding section 65 to the cylindrical section 66. The through hole 63A is the portion within the intermediate flow path through which liquid passes. The side plate section 64 is cylindrical and hangs down from the periphery of the top plate section 63. A threaded groove is provided on the inner surface of the side plate section 64 to engage with the threaded teeth of the neck 28.

[0058] The nozzle holding part 65 is cylindrical and is provided on the upper surface of the top plate part 63. The lower part of the liquid nozzle 51 is inserted into the nozzle holding part 65. An O-ring is installed between the inner circumferential surface of the nozzle holding part 65 and the outer circumferential surface of the liquid nozzle 51 to prevent liquid leakage. The cylindrical part 66 is provided on the lower surface of the top plate part 63.

[0059] The outer air hole 68 is a hole that supplies air from the outside to the interior of the container body 20 when the liquid is sprayed. The outer air hole 68 is formed through the top plate portion 63 between the side plate portion 64 and the cylinder portion 66. The outer air hole 68 communicates with the exterior of the outer fitting portion 69 at a location not shown via the interior space of the outer fitting portion 69.

[0060] The outer part 69 is generally cap-shaped with an opening facing downwards, and a connecting part 61 is housed inside. The outer diameter of the lower end of the outer part 69 is approximately the same as the outer diameter of the upper end of the body 27. When the liquid container 10 is connected to the connecting part 61, the outer part 69 forms a continuous appearance from the body 27. A nozzle hole 69A for inserting a liquid nozzle 51 is formed in the upper part of the outer part 69. The tip of the liquid nozzle 51, which is held in the nozzle holding part 65, protrudes upwards from the nozzle hole 69A.

[0061] The atomizer 50 holds the liquid nozzle 51 and the gas nozzle 53 in a predetermined positional relationship. A tip opening 52 for dispensing liquid is formed at the tip of the liquid nozzle 51. A tip opening 54 for dispensing gas is formed at the tip of the gas nozzle 53. The atomizer 50 holds the liquid nozzle 51 and the gas nozzle 53 in a positional relationship where the central axis of the tip opening 54 of the gas nozzle 53 is orthogonal to and close to the central axis of the tip opening 52 of the liquid nozzle 51. The tip openings 52 of the liquid nozzle 51 and 54 of the gas nozzle 53 are positioned within the projection plane of the liquid container 10 (approximately at the center of the cover 60) when viewed from above.

[0062] The sprayer 50 includes a handle 70 for operating to spray gas. The handle 70 is integrally elongated and rod-shaped. The handle 70 is detachably attached to the cover 60 in a horizontal (front) direction extending from the upper part of the cover 60. A gas nozzle 53 is held at the rear end of the handle 70 such that the top opening 54 protrudes rearward. The sprayer 50 is configured to spray gas rearward from the gas nozzle 53 by operating the handle 70.

[0063] like Figure 4 As shown, the handle 70 includes: a relay tube 71 connected to the gas nozzle 53 to form part of a gas passage; a relay component 72 connected to the relay tube 71 and the tube T to form part of the gas passage; a housing 73 holding the relay tube 71 and the relay component 72; an operation button 74 for opening and closing the gas passage; and a valve core 75 linked to the operation button 74. The valve core 75 is continuously forced upwards and comes into close contact with the inner circumferential surface of the relay component 72, thereby closing the gas passage. When the operation button 74 is pressed, the valve core 75 moves away from the inner circumferential surface of the relay component 72, thereby opening the gas passage. Thus, the gas filled in the gas tank B is supplied to the gas nozzle 53 via the tube T, the relay component 72, and the relay tube 71, and is ejected from the top opening 54 of the gas nozzle 53. The liquid inside the container body 20 is drawn up by the negative pressure accompanying the ejection of gas from the top opening 54 of the gas nozzle 53, and is sprayed out from the top opening 52 of the liquid nozzle 51 along with the gas jet.

[0064] like Figures 1-3 As shown, in this embodiment, the spraying device M removes the sprayer 50 from the housing body 80 during use (see reference). Figure 1 When not in use, the sprayer 50 can be placed on the housing body 80 (see reference). Figure 2 and Figure 3 The spraying device M is a structure in which the sprayer 50 is positioned offset to the right (side) relative to the central axis of the housing body 80.

[0065] The main body 80 is generally cylindrical in shape and consists of an upper shell 87 and a lower shell 88. The upper shell 87 has a mounting portion 81 for holding the sprayer 50. The mounting portion 81 protrudes to the right (side) from a part of the upper shell 87. The handle portion 70 is positioned on the mounting portion 81 such that its length direction is orthogonal to the protruding direction of the mounting portion 81. Viewed from above, the mounting portion 81 tapers at its top. On the upper surface of the upper shell 87, a descending surface 82 is formed adjacent to the left side of the mounting portion 81, descending towards the mounting portion 81. The side of the upper shell 87 curves gently downwards from the periphery of the mounting portion 81 and recedes to the left. On the side of the upper shell 87, at the position where it descends from the mounting portion 81, the other end of the tube T is connected.

[0066] like Figure 3 and Figure 4 The mounting portion 81 is provided with a locking portion 83 for locking the handle portion 70. The locking portion 83 is disposed on the protruding top portion of the mounting portion 81. The locking portion 83 has a downwardly recessed portion 84 and a portion disposed on the inner side of the recessed portion 84. Figure 4 The first magnet portion 85 is located on the lower side of the recess 84. The protruding end side (right side) of the mounting portion 81 of the recess 84 is sloping. A cutout 86 is provided on the inner surface of the recess 84, formed by cutting a portion of the left wall portion.

[0067] The handle portion 70 is provided with a locking portion 76, which locks into a locking portion 83 when the sprayer 50 is mounted on the upper housing 87. The locking portion 76 is disposed on the lower surface of the handle portion 70 between the rear end and the end to which the tube T is connected. The locking portion 76 has a downwardly protruding protrusion 77 and a portion disposed on the inner side of the protrusion 77. Figure 4 The second magnet portion 78 is located on the upper side. The protrusion 77 has protrusions that extend to the left and right. The left and right protrusions respectively engage with the cutouts 86 of the recess 84. The protrusion 77 has a shape that is 180° rotationally symmetrical about the central axis extending vertically.

[0068] Next, an example of how to use the spray device M in this embodiment will be described. When using the sprayer 50, the user holds the sprayer 50 placed on the mounting part 81 in his hand and operates the handle part 70, thereby blowing liquid and gas together onto the skin or the like at any time.

[0069] After using the sprayer 50, the user places it on the mounting portion 81. At this time, based on the positions of the cap 60 and the tube T, the locking part 76 can be integrated into the locking part 83 in the front-back direction. Furthermore, since a downward surface 82 is formed on the left side relative to the mounting portion 81, and a sloped shape is formed on the right side of the recess 84, the locking part 76 can be integrated into the locking part 83 in the left-right direction. When the locking part 76 approaches the locking part 83, the protrusion 77 engages with the recess 84, and the second magnet 78 is magnetically attracted to the first magnet 85. Thus, the locking part 76 is locked into the locking part 83, and the sprayer 50 is stably mounted on the mounting portion 81. Additionally, the handle 70 can... Figure 3 The posture shown and from Figure 3 Any one of the postures that has been rotated 180° around a rotation axis extending in the vertical direction is placed on the mounting part 81.

[0070] When the liquid in the liquid container 10 connected to the sprayer 50 is used up, it can be replenished as follows: The user reverses the liquid container 10 to release the threaded connection with the cap 60, thereby removing the used liquid container 10 from the cap 60. With the container body 20 separated from the sprayer 50, the opening 21 is open. Therefore, the user can fill the container body 20 with liquid through the opening 21. After the liquid is filled, with one end of the tube 67 pressed into the cylinder 66, the other end of the tube 67 is inserted into the liquid container 10 through the opening 21, and the liquid container 10 is rotated clockwise to thread onto the cap 60, thereby installing the liquid container 10 onto the cap 60. This completes the replenishment of the liquid in the liquid container 10.

[0071] Next, the function and effects of the first embodiment configured as described above will be explained.

[0072] In this embodiment, the opening 21 is open when the liquid container 10 is separated from the sprayer 50. Therefore, the user can easily refill the liquid through the opening 21. Thus, the user can reuse the liquid container 10, and compared to replacing the liquid container 10 each time it is used up, the user can simply purchase the liquid in its standard packaging without having to buy a new liquid container 10, saving on the cost of using the sprayer.

[0073] Furthermore, after the liquid in the liquid container 10 is used up, the user can refill it to use a different type of liquid. Therefore, the practicality of the spray device can be improved.

[0074] In this embodiment, the housing body 80 is composed of an upper housing 87 and a lower housing 88, and the locking portion 83 of the mounting portion 81 is provided on the upper surface of the upper housing 87. With this structure, the sprayer 50 can be mounted on the upper housing 87, thus making it easier to load and unload the liquid container 10 without first removing the sprayer 50 compared to when the sprayer 50 is mounted on the lower housing 88. This improves the convenience of the spraying device.

[0075] In this embodiment, the connecting portion 61 forms an outer air hole 68 that communicates the interior of the container body 20 with the exterior of the sprayer 50. With this structure, when the sprayer 50 sprays liquid and gas together, external air can flow into the interior of the container body 20. Therefore, a sufficient amount of liquid can be sprayed from the sprayer 50.

[0076] <Second Implementation Method>

[0077] The following is for reference Figures 5-10 The second embodiment of this utility model will now be described. In this embodiment, the structure of the cover 60a differs from that of the first embodiment, while the remaining components are the same as those in the first embodiment. In the following description, only the parts that differ from the first embodiment will be described; for the parts that are the same as those in the first embodiment, the same symbols will be used and their descriptions will be omitted.

[0078] In the above embodiment, the method of forming an outer air hole 68 in the connecting portion 61 has been described. However, for example, when using a gel-like cosmetic with a different viscosity as a liquid, since the size of the outer air hole 68 is fixed, the amount of air flowing into the container body 20 cannot be adjusted, and thus the spray volume of the liquid sprayed from the sprayer 50 cannot be optimized.

[0079] In this embodiment, a mechanism is provided for regulating the amount of air entering the container body 20. For example... Figures 5-7 As shown, an outer air hole 68 is formed in the connecting portion 61a, and an adjustment portion 30 is provided between the top plate portion 63a and the opening end face 22 of the opening portion 21. Figure 7 As shown, the adjustment part 30 is generally disc-shaped and has a protrusion 32 that protrudes radially outward. A cutout 64A is formed in the side plate part 64a, and the protrusion 32 extends from the cutout 64A to the area between the side plate part 64a and the outer mounting part 69a (see reference). Figure 5The length of the cut 64A in the circumferential direction is greater than the width of the protrusion 32, so that the protrusion 32 can move circumferentially within the cut 64A. A through hole 33 is formed approximately in the center of the adjusting part 30 for the cylindrical part 66 to pass through. The adjusting part 30 is in airtight contact with the cylindrical part 66 via the through hole 33 and can rotate around the cylindrical part 66. A plurality of adjusting holes 31 (three in this embodiment) are formed in the adjusting part 30, and the adjusting holes 31 penetrate the adjusting part 30 in the vertical direction.

[0080] A plurality of (three in this embodiment) outer air holes 68 are formed in the top plate portion 63, and the diameter of the outer air holes 68 is the same as the diameter of the adjustment hole 31. Furthermore, the plurality of adjustment holes 31 are arranged in such a way that they can each coincide with the plurality of outer air holes 68 when the adjustment portion 30 rotates around the cylindrical portion 66.

[0081] like Figure 5 , 9 As shown, the outer casing 69a of this embodiment has an operation window 69B, which is located radially outward of the protrusion 32 and allows the protrusion 32 to be exposed radially outward. A generally frame-shaped guide portion 69C is mounted on the outer casing 69a, and the guide portion 69C is fixed to the inner wall of the outer casing 69a in a manner that surrounds the operation window 69B. A cover member 90 is installed between the guide portion 69C and the inner wall of the outer casing 69a. The cover member 90 is large enough to cover the operation window 69B and includes an operation portion 91 and a main body portion 92. The main body portion 92 is generally rectangular and has a shape that protrudes radially outward in a manner consistent with the curvature of the outer casing 69a. The two side edges of the main body portion 92 extending in the vertical direction engage between the guide portion 69C and the inner wall of the outer casing 69a, thereby allowing the main body portion 92 to slide vertically along the guide portion 69C. The operating part 91 is located above the main body 92 and protrudes radially outward from the main body 92, so that the user can move the cover part 90 up and down through the operating part 91.

[0082] In this embodiment, the amount of air entering the container body 20 from the outer air hole 68 can be adjusted as follows. The user moves the operating part 91 downwards, causing the main body 92 to slide downwards along the guide part 69C until the operating part 91 abuts against the outer part 69a. This opens the operating window 69B (see reference). Figure 10 Next, the user moves the protrusion 32 left or right through the operation window 69B using their finger or a tool such as a stick (not shown), causing the adjustment part 30 to rotate around the cylindrical part 66. At this time, the positional relationship between the adjustment hole 31 and the outer air hole 68 changes, allowing a portion of the outer air hole 68 to be blocked by the adjustment part 30, thereby changing the area of ​​the airflow path formed by the outer air hole 68 (see reference). Figure 8 Once the adjustment is complete, the user moves the operating part 91 upwards to return the cover component 90 to its original position. Figure 5 The location shown.

[0083] Alternatively, a scale (not shown) can be formed on the side wall 34 of the adjustment section 30 near the protrusion 32. This allows the user to more intuitively understand the area of ​​the airflow path formed by the outer air hole 68 during operation.

[0084] According to this embodiment, by providing the cover component 90 and the adjustment part 30, the area of ​​the airflow path formed by the outer air hole 68 can be adjusted with a simple structure. Therefore, the user can appropriately adjust the amount of air entering the container body 20 during spraying according to the viscosity of the liquid added to the liquid container 10, thereby enabling the spraying of an appropriate amount of liquid and optimizing the spray volume of the liquid ejected from the sprayer 50.

[0085] <Variation Example>

[0086] The second embodiment described above can also be as follows: Figures 11-13 The modification was implemented accordingly. The following is an explanation of this variation.

[0087] like Figure 11 , 12 As shown, in this modified example, the structures of the outer fitting 69b and the cover member 90a differ from those in the second embodiment. In this modified example, the frame-shaped guide portion 69C, as in the second embodiment, is not provided. Instead, an annular portion 69D, coaxial with the outer fitting 69b, is provided on the inner wall of the outer fitting 69b. An opening 69Da is provided on the annular portion 69D facing the cover member 90a, and groove-shaped engaging portions 69Db extending in the vertical direction are formed on both sides of the opening 69Da in the circumferential direction. Furthermore, in this modified example, the cover member 90a is formed by cutting off a portion of the outer fitting 69b, and the cut obtained by removing this portion of the outer fitting 69b is the operation window 69B. Therefore, when the operation window 69B of the cover member 90a is closed, the outer surface of the cover member 90a and the outer surface of the outer fitting 69b are the same surface. Two plate-shaped engaging portions 90B extending in the vertical direction are installed on the inner wall of the cover component 90a. The two engaging portions 90B engage with the engaging portion 69Db of the annular portion 69D, thereby enabling the cover component 90a to move in the vertical direction. A protrusion 90C protruding radially inward is formed at the lower end of the engaging portion 90B.

[0088] In the variant example, such as Figure 13As shown, the user opens the operation window 69B by moving the cover member 90a upward. At this time, the protrusion 90C of the engaging portion 90B restricts the cover member 90a from moving further upward. After the user adjusts the area of ​​the airflow path formed by the outer air hole 68 formed in the connecting portion 61b via the protrusion 32 as described in the second embodiment, the operation window 69B can be closed by moving the cover member 90a downward until it abuts against the outer part 69b.

[0089] According to this modified example, since the cover part 90a is formed by cutting off a portion of the outer part 69b, the outer part 69b can appear as a whole when the operation window 69B is closed, thus ensuring the aesthetics of the cover part 60b.
