[0019] FIG. 4 is a vertical cross-sectional view of a vacuum cleaner according to an embodiment of the present invention, and FIG. FIG.

[0020] 1 to 5, a vacuum cleaner 1 according to an embodiment of the present invention includes a main body 2. can be done.

[0021] The vacuum cleaner 1 may further include a suction unit 5 coupled to a front side of the main body 2. The suction section 5 can guide air containing dust to the main body 2 .

[0022] The vacuum cleaner 1 may further include a handle portion 3 coupled to the main body 2. The handle portion 3 may be located on the opposite side of the main body 2 to the suction portion 5 .

[0023] That is, the main body 2 can be disposed between the suction portion 5 and the handle portion 3 .

[0024] The main body 2 includes a first body 10 and a second body 11 disposed above the first body 10. It may include a function 12.

[0025] The first body 10 and the second body 12 are formed in a cylindrical shape, but are not limited thereto. obtain.

[0026] The center of the intake portion 5 is generally between the first body 10 and the second body 11. The suction portion 5 can be coupled to the main body 2 so as to be located at the interface with the main body 2 .

[0027] The main body 2 includes a dust separating unit for separating dust from the air sucked through the suction unit 5. It may further include:

[0028] The dust separation unit may be, for example, a second dust separation unit that may separate dust by cyclone flow. The first body 10 may include a first cyclone unit 110. In this case, the first body 10 may include the first cyclone unit 110. Includes a cyclone section 110.

[0029] The air and dust sucked through the suction unit 5 are guided to the inner circumferential surface of the first cyclone unit 110. The fluid will flow in a spiral along the line.

[0030] The axis of the cyclone flow of the first cyclone unit 110 may extend in the vertical direction.

[0031] The dust separation unit separates dust again from the air discharged from the first cyclone unit 110. In this case, the dust separating unit may further include a second cyclone unit 130. The second cyclone section 130 is sized 18 in length so as to minimize size. The second cyclone unit 130 may be located inside the cyclone unit 130. The antibody may include a cytochrome P450 antibody.

[0032] As another example, the dust separating unit may have a single cyclone unit. In any case, the axis of the cyclone flow may extend in the vertical direction.

[0033] The first body 10 stores the dust separated from the cyclone units 110 and 130. The main body 2 has a button for opening and closing the lower side of the first body 10. The body cover 16 may further include a deep cover 16. The body cover 16 is rotated to The first body 10 can be opened and closed by using the opening and closing mechanism.

[0034] At least a portion of the second cyclone portion 130 may be located within the first body 10. do.

[0035] The first body 10 is provided with a storage unit for storing dust separated from the second cyclone unit 130. A dust storage guide 124 may be arranged to guide the dust storage guide 124. 2. The cyclone unit 130 is connected to the lower side of the body cover 16. can be done.

[0036] The dust storage guide 124 is arranged to divide the space inside the first body 10 into the first cycle. A first dust storage section 121 in which dust separated from the second cycle section 110 is stored, The second dust storage section 123 stores dust separated from the first dust storage section 130. can.

[0037] The internal space of the dust storage guide 124 is the second dust storage section 123. The space between the storage guide 124 and the first body 10 is a first dust storage section 121 .

[0038] At least a portion of the dust storage guide 124 is configured so that the diameter decreases from the top to the bottom. For example, a portion of the upper portion of the dust storage guide 124 may be formed as It may be formed to have a reduced diameter.

[0039] The dust storage guide 124 extends downward from the upper end of the dust storage guide 124. The shatter-proof rib 124a may include a shatter-proof rib 124a extending from the bottom of the housing 121. The dust storage guide 124 may be formed in a cylindrical shape and may surround the upper portion of the dust storage guide 124.

[0040] At this time, the diameter of the dust storage guide 124 decreases from the upper part to the lower part. Therefore, there is a gap between the outer peripheral surface of the upper part of the dust storage guide 124 and the scattering prevention rib 124a. A space is formed.

[0041] The cyclone flow can flow down along the inner circumferential surface of the second body 10. In the process of the cyclone flow descending, the cyclone flow can When the first dust particles come into contact with the first dust particles 16, the rotational flow may change to an upward flow. When an upward flow exists in the storage unit 121, the dust stored in the first dust storage unit 121 is There is a problem that the liquid may scatter and flow back into the second cyclone section 130.

[0042] In the present invention, the upward flow in the first dust storage portion 121 is caused by the scattering prevention rib 124a. and the upper part of the dust storage guide 124 by the scattering prevention rib 124a. Since the flow is changed to a downward flow again, the dust stored in the first dust storage portion 121 is prevented from scattering. As a result, the problem of dust flowing back to the second cyclone unit 130 can be prevented. .

[0043] On the other hand, the scattering prevention rib 124a extends downward from the upper end of the dust storage guide 124. Therefore, the dust separated from the first cyclone unit 110 along with the cyclone flow is The scattering prevention rib 124a allows the dust particles to move smoothly into the first dust storage portion 121. can.

[0044] The body cover 16 includes the first dust storage portion 121 and the second dust storage portion 123. Both can be opened and closed.

[0045] The vacuum cleaner 1 includes a suction motor 20 for generating a suction force, and a power supply for the suction motor 20. and a battery 40 for providing a power source.

[0046] The suction motor 20 may be located within the second body 12. At least a part of the motor 20 may be located above the dust separating unit. The motor 20 may be located above the first body 10 .

[0047] The suction motor 20 may be in communication with the outlet of the second cyclone unit 130. .

[0048] For this purpose, the main body 2 includes a discharge guide 28 connected to the second cyclone unit 130. and a flow guide 22 in communication with the discharge guide 28.

[0049] For example, the discharge guide 28 is located above the second cyclone unit 130, The flow guide 22 may be located above the discharge guide 28 .

[0050] At least a part of the suction motor 20 is located inside the flow guide 22. obtain.

[0051] Therefore, the axis of the cyclone flow of the first cyclone unit 180 is the axis of the suction motor 2 It can penetrate 0.

[0052] When the suction motor 20 is positioned above the second cyclone unit 130, The air discharged from the clamp portion 130 can immediately flow to the suction motor 20 side. Therefore, the flow path between the dust separator and the suction motor 20 can be minimized.

[0053] The suction motor 20 includes an impeller 200 that rotates. The roller 200 may be connected to a shaft 202. The shaft 202 may extend in an up-down direction. will be placed in.

[0054] The impeller 200 is positioned at the upper side of the suction motor 20. In this case, the impeller 200 is arranged to suck air into the intake motor. The fluid can flow from the top to the bottom of the rotor 20.

[0055] The extension line of the shaft 202 (which can also be called the rotation axis of the impeller 200) is At this time, the impeller 200 and the dust separator 10 can pass through the impeller 200. The axis of the cyclone flow generated from the first cyclone section 110 at the remote position can be aligned in the same line. do.

[0056] According to the present invention, the air discharged from the dust separation unit, i.e., the second cyclone unit 1 The air discharged upward from the intake duct 30 has a reduced path to flow toward the intake motor 20. This has the advantage of reducing the directional change and therefore reducing air flow loss.

[0057] When the air flow loss is reduced, the suction force increases, and the suction motor 20 is supplied with power. This increases the battery life of the battery 40.

[0058] The vacuum cleaner 1 includes an upper motor housing 20 which covers a part of the upper side of the suction motor 20. 26 and a lower motor housing 27 which covers a part of the lower side of the suction motor 20. It can be included in the following:

[0059] The suction motor 20 is housed inside the motor housing 26, and the flow guide The motor housing 22 may be disposed to surround the upper motor housing 26 .

[0060] At least a portion of the flow guide 22 is spaced apart from the upper motor housing 26. In addition, at least a part of the flow guide 22 is separated from the second body 12. It can be separated.

[0061] Therefore, the inner peripheral surface of the flow guide 22 and the outer peripheral surface of the upper motor housing 26 2, a first air passage 232 is formed, and the outer circumferential surface of the flow guide 22 and the second body 12 are The inner circumferential surface defines a second air flow passage 234 .

[0062] In accordance with the present invention, a single air flow guide 22 includes a first air passage 232 and a second air passage 234. This simplifies the structure by reducing the number of parts required to form each air flow path. There is an advantage to being able to do this.

[0063] The first air passage 232 serves as an intake passage, and the second air passage 234 serves as an exhaust passage. Plays the role of.

[0064] The air discharged from the second cyclone unit 130 flows along the first air flow path 232. The air that flows into the suction motor 20 and is discharged from the suction motor 20 is the second air The air flows along the flow path 234 and is then discharged to the outside. 4 serves as an exhaust flow path.

[0065] The handle portion 3 includes a handle 30 for a user to grasp, and a lower part of the handle 30. and a battery housing 410 disposed in the

[0066] The handle 30 may be located rearward of the suction motor 20 .

[0067] The direction is defined as the forward direction with respect to the suction motor 20 in the vacuum cleaner 1. The direction in which the suction unit 5 is located is the front, and the direction in which the handle 30 is located is the rear. .

[0068] The battery 40 may be located at the rear of the first body 10. The suction motor 20 and the battery 40 are arranged so as not to overlap each other in the vertical direction. Alternatively, they may be arranged differently.

[0069] According to the present invention, the suction motor 2, which is heavy based on the handle 30, 0 is located in front of the handle 30, and the heavy battery 40 is located in front of the handle 30. Since it is located at the bottom, the weight of the vacuum cleaner 1 is evenly distributed throughout the vacuum cleaner. When holding the handle 30 for cleaning, strain on the user's wrist can be prevented. That is, the heavy components are distributed at the front and rear of the vacuum cleaner 1, and the weights are different from each other. Since it is disposed at a height, the center of gravity of the vacuum cleaner 1 can be prevented from tilting to one side.

[0070] The battery 40 is located below the handle 30, and the suction motor 20 is Since the handle 30 is located in front of the handle 30, there is no structure above the handle 30. That is, the upper surface of the handle 30 forms part of the exterior of the upper surface of the vacuum cleaner 1.

[0071] Therefore, in the process of using the vacuum cleaner 1 by grasping the handle 30, a certain configuration of the vacuum cleaner 1 is Contact with the arm can be prevented.

[0072] The handle 30 has a first extension 310 that extends vertically and can be grasped by a user. and a second extension portion 310 extending from the upper side of the first extension portion 310 toward the suction motor 20. 20. The second extension portion 320 may extend at least partially in a horizontal direction. do.

[0073] The first extension 310 is configured such that the user's hand is in contact with the first extension 310 when the user grasps the first extension 310. 1. A movement control for preventing the extension part 310 from moving in the length direction (up and down direction in FIG. 2). The movement limiting portion 312 may be provided from the first extension portion 310. It may extend towards the intake portion 5 .

[0074] The movement limiting portion 312 is spaced apart from the second extending portion 320. When the first extension portion 310 is held, some of the fingers are positioned above the movement limiting portion 312. , the remaining fingers may be positioned below the movement limiter 312 .

[0075] As an example, the movement limiter 312 may be located between the index finger and the middle finger.

[0076] According to this arrangement, the user can hold the first extension 310 and press the inlet port 314. 5's longitudinal axis A1 can pass through the user's wrist.

[0077] When the longitudinal axis A1 of the inhalation unit 5 passes through the wrist of the user, The longitudinal axis A1 of the inhalation portion 5 may be substantially aligned with the extension of the user's arm. Therefore, in such a state, the user cannot grasp the handle 30 and operate the vacuum cleaner 1. This has the advantage that the force required by the user is minimized when pushing or pulling.

[0078] The handle 30 may include an operating portion 326. 6 may be located on an inclined surface formed on the second extension portion 320. On and off commands for the vacuum cleaner suction motor can be input.

[0079] The operation portion 326 may be disposed so as to face the user. The operating portion 326 may be located on the opposite side of the movement limiting portion 312 .

[0080] The operating portion 326 may be located higher than the movement limiting portion 312. While holding the first extension portion 310, the user can easily operate the operating portion 326 with his / her thumb. It is possible.

[0081] In addition, since the operating portion 326 is located at a position separated from the first extension portion 310, When cleaning is performed while holding the first extension portion 310, the operating portion 326 may be unintentionally operated. This can prevent the above from happening.

[0082] The second extension portion 320 may include a display portion 322 for displaying an operating state. For example, the display unit 322 may be located on an upper surface of the second extension unit 320. In this way, the user can see the display unit 322 located on the upper surface of the second extension part 320 while cleaning. The display unit 322 can easily display the remaining charge of the battery 40, The strength of the suction motor etc. can be displayed.

[0083] The display unit 322 may include, but is not limited to, a plurality of light emitting units. The light emitting parts may be arranged in a longitudinal direction of the second extension part 320 at intervals.

[0084] The battery housing 410 may be located below the first extension 310 .

[0085] The battery 40 may be releasably coupled to the battery housing 410 . In one example, the battery 40 is inserted from below the battery housing 410. The battery housing 410 may be inserted inside the battery housing 410.

[0086] The rear surface of the battery housing 410 and the rear surface of the first extension portion 310 are continuous. Therefore, the battery housing 410 and the first extension 420 can form a surface. The long portion 310 can have a sense of unity.

[0087] The battery 40 is housed in the battery housing 410. Therefore, when the vacuum cleaner 1 is placed on the floor, The battery 40 can then be placed on the floor.

[0088] According to this structure, the battery 40 can be removed from the battery housing 410. This has the advantage that it can be separated immediately.

[0089] In addition, since the bottom surface of the battery 40 is exposed to the outside, The battery 40 can be in direct contact with the air outside the vacuum cleaner 1, and the cooling performance of the battery 40 can be improved.

[0090] Meanwhile, referring to FIG. 3, the vacuum cleaner 1 is a vacuum cleaner in which air passing through the suction motor 20 is discharged. The air outlet 522 may further include a filter mechanism 50 having an air outlet 522. The outlet 522 may, for example, include a plurality of openings, which may be arranged in a circumferential direction. Thus, the air outlets 522 may be arranged in a ring shape.

[0091] The filter mechanism 50 can be releasably coupled to the upper side of the main body 2. The caster mechanism 50 can be detachably housed in the second body 12 .

[0092] A part of the filter mechanism 2 when the filter mechanism 50 is coupled to the main body 2 The second body 12 may be located outside the second body 12. The part is inserted into the inside of the main body 2 through the upper opening of the main body 2, and the other part is inserted into the main body 2. protrudes outside.

[0093] The height of the main body 2 may be substantially the same as the height of the handle 30. The filter mechanism 50 protrudes upward from the main body 2, so that the user can The filter mechanism 50 can be easily separated while the mechanism 50 is grasped.

[0094] The filter mechanism 50 is attached to the main body 2. The air outlet 522 may be located on the side of the suction motor 20. The air is discharged upward from the main body 2 .

[0095] According to the present embodiment, during the cleaning process using the vacuum cleaner 1, air is exhausted from the air outlet 522. The released air may be prevented from flowing towards the user.

[0096] The main body 2 includes a pre-filter for filtering the air flowing into the suction motor 20. The flow guide 22 may further include a pre-filter 29. The pre-filter 29 may be located within the upper motor housing 26. The upper motor housing 26 may be attached to the upper motor housing 26 to surround a portion of the upper motor housing 26. The motor housing 26 has a filter support portion for supporting the pre-filter 29. It can include.

[0097] When the filter mechanism 50 is attached to the main body 2, the filter mechanism 50 is Pressurizing the pre-filter 29 to prevent movement of the pre-filter 29. can be done.

[0098] In one example, the filter mechanism 50 may press the pre-filter 29 downward. Therefore, according to the present invention, the structure for fixing the pre-filter 29 is The advantage is that it does not require

[0099] FIG. 6 is a view showing a state in which a filter mechanism according to an embodiment of the present invention is separated from a main body. FIG. 7 is a bottom view of a filter mechanism according to one embodiment of the present invention, and FIG. FIG. 8 is an exploded perspective view of the filter mechanism of FIG. 7; FIG. 9 is a cross-sectional perspective view of the filter mechanism of FIG. It is.

[0100] 5 to 9, the filter mechanism 50 can be separated from the main body 2. do.

[0101] As an example, the filter mechanism 50 may be separate above the main body 2 .

[0102] The impeller 200 is disposed above the suction motor 20. The pre-filter 29 is disposed in the upper motor housing 20 so as to cover the impeller 200. 26.

[0103] Therefore, when the filter mechanism 50 is separated from the main body 2, the prefix The pre-filter 29 can be exposed to the outside, so that the pre-filter 29 can be separated. It becomes possible.

[0159] FIG. 11 is a perspective view of a filter cover according to an embodiment of the present invention, and FIG. FIG. 13 is a cross-sectional view showing the state in which the inner frame is joined to the filter cover of FIG. FIG. 13 is a perspective view of a flow guide according to an embodiment of the present invention; FIG.

[0160] 10 to 14, the filter cover 570 is formed on the inner body 571, an outer body 572 spaced apart from the inner body 571, and A connecting body 573 that connects the inner body 571 and the outer body 572 is provided. It can include.

[0161] The inner body 571 and the outer body 572 are each formed in a ring shape. It can be done.

[0164] The inner circumferential surface of the inner body 571 is provided with ribs for coupling with the flow guide 22. A coupling portion 577 may be provided.

[0165] The inner body 571 is extended so that the rib connection portion 577 extends downwardly. The extension 576 may include an extension portion 576 extending downward from the inner body 571. The extension 576 may have the rib connection portion 577 projecting downward from the surface.

[0166] Therefore, the rib joint 577 is circumferentially connected to the end of the frame support rib 575. and extends obliquely downward.

[0167] The reason why the rib connection portion 577 is inclined downward is that the filter mechanism 50 is attached to the main body 2. The filter mechanism 50 can be connected and disconnected in a rotating manner, and can be separated from the main body 2. This is to allow the filter mechanism 50 to rise during the process of releasing.

[0168] When the filter mechanism 50 is lifted during the process of being separated, The user can confirm that they are separated.

[0169] The filter mechanism 50 is rotated so that the filter mechanism 50 is released from the coupling. When configured in this way, a rotational force must be applied to the filter mechanism 50. The filter mechanism 50 can be prevented from being separated from the main body 20 even if it is pulled. Therefore, the filter mechanism 50 is prevented from being unintentionally separated from the main body 2. It can be prevented.

[0170] The rib connection portion 577 is a slot in which a fixing protrusion 229 of the flow guide 22 described later is accommodated. The slot 578 may include a groove or a hole.

[0171] The inner frame 501 extends downward at a lower surface 509 of the inner frame 501. The filter may further include a contact portion 509a extending from the contact portion 509a. When the cover 570 and the inner frame 501 are joined together, the frame support ribs The side of 575 can be touched.

[0172] The inner frame 501 is configured to receive the fixing rib 228 formed on the flow guide 22. The recess 50 is recessed upward to form a rib receiving portion 579 for receiving the rib. It may contain 9b.

[0173] When the inner frame 501 is coupled to the filter cover 570, The recess 509b is disposed above the connecting rib 577 and spaced apart from the connecting rib 577. do.

[0174] At this time, the flow guide 22 is fixed during the rotation and lowering of the filter mechanism 50. The rib 228 is received in the rib receiving portion 579 between the recess 509b and the rib connecting portion 577. To accommodate this, the recess 509b may be formed to be inclined.

[0175] Therefore, the rib receiving portion 579 also extends downwardly. 79 is understood to be a space between the inner frame 501 and the filter cover 570. That is, the fixing rib 228 of the flow guide 22 can be fixed to the inner frame 5. 01 and the filter cover 570.

[0176] The flow guide 22 includes a guide body 220 having an open upper and lower portion. The guide body 220 is configured to receive the evacuated air discharged from the second cyclone unit 130. The air passage may include a passage forming wall 222 for forming the first air passage 232 through which air flows. can.

[0177] The flow passage forming wall 222 may protrude in a radial direction from the guide body 222. do.

[0178] At this time, the flow guides 22 are spaced apart in the circumferential direction so that the air can flow smoothly. A plurality of channel-forming walls 222 may be included.

[0179] The suction motor 20 is located inside the flow guide 22. In order to prevent this increase, the gap between the flow guide 22 and the suction motor 20 must be large. However, the gap between the flow guide 22 and the suction motor 20 must be large. If the airflow is too large, there is a problem of reduced air flow performance.

[0180] However, as in the present invention, the flow passage forming wall 222 protrudes from the guide body 220. Then, the flow passage forming wall 222 ensures a sufficient cross-sectional area of ​​the flow passage through which air can flow. , air flow performance can be improved.

[0181] The upper part of the flow guide 22 can be accommodated inside the inner frame 501. In addition, the flow passage forming wall 222 is formed so as not to interfere with the filter mechanism 50. The forming wall 222 is formed at a position spaced apart from the upper end of the flow guide 22 downward at a predetermined interval. can be.

[0182] The outer diameter of the upper part of the guide body 220 is The inner diameter of the filter mechanism 50 may be smaller than the inner diameter of the peripheral portion 503. When coupled to the main body 2, the upper portion of the flow guide 22 is received in the filter mechanism 50. The inner sealing member 530 may be seated on the upper end of the flow guide 22. .

[0183] According to the present invention, a portion of the flow guide 22 is housed inside the filter mechanism 50. Therefore, the increase in height of the vacuum cleaner 1 can be minimized.

[0184] The guide body 220 has an inner peripheral surface on which a filter supporting the lower end of the pre-filter 29 is provided. The filter support portion 225 may be provided on the guide. It can protrude from the inner circumferential surface of the body 220.

[0185] The lower end of the guide body 220 is provided with a A fastening portion 226 for fastening the mounting bracket 222 may be provided.

[0186] The fastening portion 226 of the guide body 220 is seated on the upper motor housing 26. In this state, the fastening member S1 penetrates the fastening portion 226 from above, and then the upper motor The connector 22 can be fastened to the data housing 26.

[0187] The fastening member S1 is fastened to the upper motor housing 26 and the lower motor housing After passing through the discharge guide 27, the discharge guide 28 can also be fastened to the discharge guide 28. Since the assembly can be performed using a small number of fastening members, the structure and assembly method are simple. This has the advantage that

[0188] The flow guide 22 includes a fastening rib 228 for attachment to the filter mechanism 50. The height of the filter mechanism 50 can be adjusted by rotating the filter mechanism 50. The fixing ribs 22 may extend circumferentially and inclined in a variable manner; and A fixing protrusion 229 may be formed on the lower surface of the fixing rib 22 .

[0189] Meanwhile, the flow passage forming wall 222 may be formed with a reinforcing rib 227. 2 is spaced apart from the inner circumferential surface of the second body 12 to form the second air passage 234. obtain.

[0190] The reinforcing rib 227 extends from the flow passage forming wall 222 toward the second body 12. obtain.

[0191] In this manner, when the flow guide 22 is spaced from the inner circumferential surface of the second body 12, When an external force is applied from the outside of the second body 12, the second body 12 is moved toward the fluid gas. There is a risk of it being transformed towards Ido 22.

[0192] However, according to the present invention, the flow passage forming wall 222 is provided with a reinforcing rib 227. Therefore, even if an external force is applied to the second body 12, the second body 12 is supported by the reinforcing rod. As a result, the second body 12 comes into contact with the projection 227, and deformation of the second body 12 can be restricted.

[0193] Since the flow passage forming wall 222 protrudes from the guide body 220, the reinforcing rib 2 When the reinforcing rib 227 is formed on the flow passage forming wall 222, the length of the reinforcing rib 227 is reduced. It has the advantage of being able to

[0195] The process of assembling the filter mechanism 50 will now be described with reference to FIGS. I decided to do so.

[0196] In order to connect the filter mechanism 50 to the main body 2, A portion of the side is accommodated in the second body 12.

[0197] As a result, the rib receiving portion 579 of the filter mechanism 50 and the fixing rib 228 are can be aligned.

[0198] When the filter mechanism 50 is rotated in this state, the fixing rib 228 moves to the rib collecting member 226. At this time, the fixing rib 228 is easily inserted into the rib receiving portion 579. In order to be received in the rib receiving portion 579, the height of the rib receiving portion 579 is higher than the height of the fixing rib 228. It can be formed.

[0199] Since the fixing rib 228 extends at an angle, the filter mechanism 50 is rotated. The filter mechanism 50 is then lowered by the fixing rib 228 .

[0200] When the fixing rib 228 is received in the rib receiving portion 579, the fixing protrusion 229 When inserted into slots 578 of rib joint 577, the filter mechanism 50 and The connection with the main body 2, i.e., the connection with the flow guide 22, is completed.

[0201] On the other hand, in order to separate the filter mechanism 50 from the main body 2, 50 is rotated in the other direction. At this time, the fixing rib 228 is formed to be inclined. Therefore, during the rotation of the filter mechanism 50, the filter mechanism 50 is fixed to the fixing rib 22. 8. Then, the fixed rib 228 is lifted from the rib receiving portion 579. When the filter mechanism 50 is pulled out from the main body 2, the filter mechanism 50 is released from the main body 2.

[0202] In this state, when the filter mechanism 50 is moved upward, the filter mechanism 50 It can be separated from the body 2 .
