Description

Technical Field

[0001] The present invention relates to a filter cleaning device provided in a vehicle air conditioner such as an automobile. Background Art

[0002] When a vehicle air conditioner takes in external air, conditions the air, and delivers it to the room, the external air is purified by a filter and then supplied to the room. Dust contained in the external air accumulates on the filter, causing clogging, so the filter needs to be cleaned. In addition, when the internal air is circulated indoors, a filter is also provided to purify dust generated indoors, so the dust accumulated on the filter needs to be cleaned. In addition, an invention that automates the cleaning of the filter is known in the past (Patent Document 1).

[0003] The vehicle air conditioning device described in Patent Document 1 is constructed as follows: if the glove box is opened to store or take out small items, the cable pulls the brush box, and the scraping component removes foreign matter on the air filter and discharges it from the exhaust pipe. If the glove box is closed, the brush box and the scraping component are returned to their original positions by pulling the coil spring. Prior art literature Patent Literature

[0004] Patent Document 1: Japanese Patent Application Publication No. 2007-216712 Summary of the invention Technical Problems to be Solved by the Invention

[0005] The vehicle air conditioning device described in Patent Document 1 does not require a motor to drive the scraping member, nor does it require wiring to supply power to the motor, so it is a device that can achieve a reduction in manufacturing cost. However, when the glove box is not opened or closed, dust accumulates on the filter, causing clogging.

[0006] The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a filter cleaning device that can reduce manufacturing costs because it does not require a motor and electrical wiring, and can frequently clean the filter every time a vehicle is used. Technical solutions for solving technical problems

[0007] In order to solve the above-mentioned previous problems, the invention of method 1 is a filter cleaning device, characterized in that it is arranged in an air-conditioning device for a vehicle, and the filter cleaning device comprises: a filter body, which has a filter and a filter frame; a dust removal body, which knocks the filter body or applies vibration to the filter body to peel off the dust attached to the filter body; and a movable mechanism, which supports the dust removal body and controls the movement of the dust removal body, and the movable mechanism utilizes the inertial force generated by acceleration, deceleration and steering of the vehicle to make the dust removal body move relative to the filter.

[0008] In the invention of mode 1, the following configuration is adopted: the movable mechanism is controlled so that the dust removal body can move relative to the filter by utilizing the inertial force generated by the acceleration, deceleration and steering of the vehicle, so that a motor and electrical wiring are not required, and the manufacturing cost can be reduced. In addition, since the inertial force generated by the acceleration, deceleration and steering of the vehicle is generated every time the vehicle is used, the filter can be cleaned frequently. In addition, since the dust is peeled off by tapping the filter body or applying vibration to the filter body, the fine dust contained in the exhaust gas etc. entering the inside of the filter can be effectively removed.

[0009] The invention of mode 2 is based on the invention of mode 1, and the movable mechanism has a rod-shaped or rail-shaped support platform for holding the dust removal body, one end or both ends of the support platform are fixed near the filter, and the dust removal body moves along the long side direction of the support platform using the inertial force generated by the acceleration, deceleration and steering of the vehicle. In this way, the inertial force can be converted into a force along the long side direction of the support platform for use. In addition, since the dust removal body can be used to knock a specified part of the filter, dust can be effectively removed.

[0010] The invention of mode 3 is based on the invention of mode 1, and the movable mechanism comprises: a rod-shaped or track-shaped support platform for holding the dust removal body; and a guide track for sliding contact with and supporting a sliding contact portion formed at the end or central portion of the support platform, wherein the support platform reciprocates along the long side direction of the guide track by utilizing the inertial force generated by the acceleration, deceleration and steering of the vehicle, and the guide track is arranged near the end of the filter, and the dust removal body is fixed to the support platform or moves along the long side direction of the support platform by utilizing the inertial force generated by the acceleration, deceleration and steering of the vehicle. Thus, the inertial force can be converted into a force along the linear direction of the filter for utilization. In addition, since the dust removal body can be used to hit a wide range of the filter, the dust on the entire filter can be removed efficiently.

[0011] The invention of mode 4 is based on the invention of mode 3, wherein a buffer device is provided near the end of the guide rail in the long side direction, and the buffer device generates a repulsive force on the support platform when the support platform approaches or abuts against the support platform, thereby relieving the collision with the guide rail. Thus, even when a large inertial force is applied, damage to the movable mechanism can be prevented.

[0012] The invention of mode 5 is based on the invention of mode 3, wherein the load per unit length of the support platform in the long side direction near the sliding contact portion supported by the guide rail is greater than the load per unit length outside the sliding contact portion of the support platform. As a result, the inertial force acting on the support platform can be increased, and deformation of the support platform can be suppressed, so that the support platform can slide smoothly on the guide rail.

[0013] The invention of mode 6 is based on the invention of mode 1, and the movable mechanism has a rod-shaped or rail-shaped support platform for holding the dust removal body, one end of the support platform can be rotatably fixed to the rotating shaft near the filter, and the other end becomes a free end that can reciprocate, and the dust removal body is fixed to the support platform or moves along the long side direction of the support platform using the inertial force generated by the acceleration, deceleration and steering of the vehicle. In this way, the movable mechanism can be simplified and the manufacturing cost can be reduced.

[0014] The invention of mode 7 is based on the invention of mode 1, and the movable mechanism has a support platform in a roughly cover shape, which is arranged at a position opposite to the filter across the dust collector, and the dust collector freely moves along the support platform using the inertial force generated by the acceleration, deceleration and steering of the vehicle. As a result, the movable mechanism can be simplified and the manufacturing cost can be reduced. In addition, since the dust collector is not constrained by a track or the like, it can move smoothly in the direction of the inertial force.

[0015] The invention of mode 8 is based on the invention of mode 2 or mode 3, wherein a buffer device is provided near the end of the long side direction of the support platform, and the buffer device generates a repulsive force on the dust removal body when the dust removal body approaches or abuts against the dust removal body, thereby relieving the collision with the support platform. Thus, even when a large inertial force is applied, damage to the movable mechanism can be prevented.

[0016] The invention of mode 9 is based on the invention of any one of modes 1 to 7, wherein the filter has a plurality of pleats, and the dust removal body taps the pleats or applies vibration to the pleats to remove dust attached to the filter. Thus, the dust removal body can remove dust by tapping the filter having a plurality of pleats or applying vibration, thereby simplifying the movable mechanism and reducing the manufacturing cost.

[0017] The invention of method 10 is based on the invention of method 9, and the dust collector is roughly spherical, and uses the inertial force generated by the acceleration, deceleration and steering of the vehicle to roll on the filter surface and knock the pleats. As a result, the movable mechanism can be further simplified, and the manufacturing cost can be reduced. In addition, although the dust collector exerts an impact on the filter, it can reduce excessive friction with the filter, thereby improving durability and reducing maintenance frequency.

[0018] The invention of mode 11 is based on the invention of mode 9, wherein the filter has a reinforcement portion for maintaining the shape at a part of the pleats, and the dust collector applies vibration to the filter by tapping the reinforcement portion. Thus, the durability of the filter having a plurality of pleats can be improved by the reinforcement portion. In addition, by maintaining the shape of the filter, the dust collector can easily apply impact and easily transmit impact to the entire filter, so that dust can be removed more efficiently.

[0019] The invention of mode 12 is based on the invention of any one of modes 1 to 7, and in the movable mechanism, the long side direction of the guide rail or the support platform is formed to be inclined relative to the horizontal direction. Therefore, even when the vehicle is not subjected to inertial force, gravity acts on the dust collector to move the dust collector toward one end of the filter, which can prevent the dust collector from stopping in the middle of the filter and hindering ventilation to the room.

[0020] The invention of mode 13 is based on the invention of any one of modes 1 to 7, and a dust box is formed near the filter and on at least one side in a direction perpendicular to the moving direction of the dust removal body. Thus, dust peeled from the filter by the dust removal body can be accumulated in the dust box, and the accumulated dust can be collected and discharged to the outside.

[0021] The invention of mode 14 is based on the invention of any one of modes 1 to 7, wherein the movable mechanism includes a position where the dust remover and the filter body are not in contact within the range of motion of the dust remover. As a result, the filter body can be strongly struck or vibrated, so that dust can be reliably peeled off the filter. In addition, the initial movement of the dust remover becomes smooth, and the dust remover can be efficiently moved even with a relatively small inertial force of the vehicle. Effects of the Invention

[0022] The invention of mode 1 does not require a motor and electrical wiring, can reduce manufacturing costs, and can frequently clean the filter. In addition, the invention of mode 2 can convert the inertial force into a force along the long side direction of the support platform for use. In addition, the invention of mode 3 can convert the inertial force into a force along the linear direction of the filter for use.

[0023] The invention of mode 4 and the invention of mode 8 can prevent the movable mechanism from being damaged even when a large inertial force is applied. In addition, the invention of mode 5 can increase the inertial force acting on the support table, and can also suppress the deformation of the support table, so that the support table can slide smoothly on the guide rail. In addition, the inventions of mode 6, mode 7, mode 9 and mode 10 can simplify the movable mechanism and reduce the manufacturing cost.

[0024] The invention of aspect 11 can improve the durability of the filter having a plurality of pleats by the reinforcement portion. In addition, the invention of aspect 12 can prevent the dust removal body from stopping at the middle position of the filter and hindering ventilation to the room.

[0025] The invention of aspect 13 can make the dust peeled off from the filter by the dust removal body accumulate in the dust collecting box, and can collect and discharge the accumulated dust to the outside. In addition, the invention of aspect 14 can reliably peel the dust from the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to the embodiment. Figure 1 (a) is a cross-sectional view showing a state where the filter cleaning device of the present invention is installed in a vehicle air conditioning system, Figure 1 (b) is a perspective view showing a first embodiment of the filter cleaning device of the present invention. Figure 2 (a) is a side view when the inertial force acts toward the rear of the vehicle. Figure 2 (b) is a side view when the inertial force acts toward the front of the vehicle. Hereinafter, a first embodiment of the filter cleaning device of the present invention will be described using these drawings.

[0028] The filter cleaning device 10 of the first embodiment is provided in a vehicle air conditioning device, such as Figure 1 As shown in (a), the filter cleaning device 10 is installed on the upstream side of the blower fan 82 installed in the vehicle air conditioner main body case 81 via the base 9 in the air duct that introduces the outside air from the arrow direction, and supplies the air that has passed through the filter body 1 to the room.

[0029] The filter cleaning device 10 comprises: a filter body 1, which comprises a filter 1a and a filter frame 1b; a dust removal body 2, which knocks the filter body 1 or applies vibration to the filter body 1 to peel off the dust attached to the filter body 1; and a movable mechanism 3, which supports the dust removal body 2 and controls the movement of the dust removal body 2.

[0030] The movable mechanism 3 utilizes the inertial force generated by the acceleration, deceleration and steering of the vehicle to enable the dust removal body 2 to move relative to the filter 1a. As a result, a motor and electrical wiring are not required, and the vehicle's electricity is not used, so there is no burden on the overall power consumption of the vehicle. It is an environmentally friendly structure and can achieve a reduction in manufacturing costs. In addition, since the inertial force generated by the acceleration, deceleration and steering of the vehicle is generated every time the vehicle is used, the filter 1a can be cleaned frequently. In addition, since the filter body 1 is knocked or vibration is applied to the filter body 1 to peel off the dust, it is possible to effectively remove the fine dust contained in the exhaust gas that enters the interior of the filter 1a. In addition, it is also possible to have a structure in which the dust removal body 2 knocks the filter frame 1b and applies an impact, and this structure is also included in the present invention.

[0031] The movable mechanism 3 has a rod-shaped or track-shaped support platform 4 for holding the dust collector 2. One end or both ends of the support platform 4 are fixed near the filter 1a, and the dust collector 2 moves along the long side direction of the support platform 4 using the inertial force generated by the acceleration, deceleration and steering of the vehicle. In this way, the inertial force can be converted into a force along the straight line direction of the filter for utilization. In addition, since the dust collector 2 is used to knock a specified part of the filter 1a, dust can be effectively removed. In addition, the support platform is conceived to have a polygonal or circular cross-section in the case of a rod, and is conceived to be a track that supports the dust collector from both sides or a track that supports only one side in the case of a track. As long as it is a component that has the function of supporting the dust collector, it is included in the present invention.

[0032] The filter 1a is constructed as follows: it has a plurality of pleats, and the dust removal body taps the pleats or applies vibration to the pleats, thereby removing dust attached to the filter. Therefore, since the dust removal body can tap or apply vibration to the filter 1a having a plurality of pleats to remove dust, the movable mechanism 3 can be simplified and the manufacturing cost can be reduced. In addition, although not shown in the figure, in the case of a planar filter, the dust removal body taps or applies impact to the surface of the filter in a vertical direction to remove dust attached to the filter, and this method is also included in the present invention. In addition, the case where the dust removal body does not directly tap the filter but taps the filter frame to apply impact to the entire filter body is also included in the present invention.

[0033] In addition, the structure is as follows: the filter 1a has a reinforcement part 1c for maintaining the shape in a part of the pleats, and the dust collector 2 applies vibration to the filter 1a by tapping the reinforcement part 1c. Thus, the durability of the filter 1a having multiple pleats can be improved by the reinforcement part 1c. In addition, by maintaining the shape of the filter 1a, the dust collector 2 is easy to apply impact, and it is easy to transmit the impact to the filter 1a as a whole, which can more efficiently remove dust. In addition, the structure of the reinforcement part is assumed to be resin or hot melt, but as long as it has the function of reinforcing the filter, it is included in the present invention.

[0034] The dust removal body 2 is constructed as follows: it is a roughly spherical body, and uses the inertial force generated by the acceleration, deceleration and steering of the vehicle to roll on the surface of the filter 1a and tap the pleats. As a result, the movable mechanism 3 can be further simplified, and the manufacturing cost can be reduced. In addition, although the dust removal body 2 exerts an impact on the filter, it can reduce excessive friction with the filter 1a, thereby improving durability and reducing maintenance frequency.

[0035] The movable mechanism 3 is constructed as follows: the long side direction of the support platform 4 is formed to be inclined relative to the horizontal direction. Therefore, even when the vehicle is not subjected to inertial force, gravity acts on the dust collector 2, so that the dust collector 2 can be moved to a certain end side of the filter 1a, and the dust collector 2 can be prevented from stopping in the middle of the filter and thus hindering ventilation to the room.

[0036] In addition, the movable mechanism 3 is preferably configured as follows: the movable range of the dust remover 2 includes a position where the dust remover 2 and the filter body 1 do not abut. As a result, the filter body 1 can be strongly struck or vibrated, so that dust can be reliably peeled off the filter 1a. In addition, the initial movement of the dust remover becomes smooth, and the dust remover can be efficiently moved even with a relatively small inertial force of the vehicle.

[0037] Here, the inertial force is generated by the acceleration, deceleration and steering of the vehicle. When the vehicle is accelerating, Figure 2 As shown in (a), the inertial force acts from the front to the rear of the driver, so the inertial force also acts from the front to the rear of the vehicle on the movable mechanism 3 of the filter cleaning device 10, causing the dust removal body 2 located on the vehicle front side of the filter body 1 to move toward the vehicle rear side of the filter body 1. On the contrary, when the vehicle is decelerated, as shown in Figure 2 As shown in (b), the inertial force acts from the rear to the front of the driver, so the inertial force also acts from the rear to the front of the vehicle on the movable mechanism 3 of the filter cleaning device 10, causing the dust collector 2 located on the rear side of the filter body 1 to move toward the front side of the filter body 1. In addition, although not shown, the inertial force is generated by changing the direction of travel of the vehicle by turning, so that the dust collector 2 moves relative to the filter body 1. In addition, even in the case where the surface of the filter body 1 is erected in the vertical direction and arranged so that the surface faces the front-rear direction or the left-right direction, the inertial force generated by the acceleration and deceleration of the vehicle and the inertial force caused by changing the direction of travel of the vehicle by turning can be used to make the dust collector move relative to the filter body.

[0038] Figure 3 (a) and (b) are perspective views showing a second embodiment of the filter cleaning device of the present invention. Figure 3 (a) View from the downstream side of the filter, Figure 3 (b) View from the upstream side of the filter. Figure 3(b) shows a state where the base 9 is removed. In addition, it is assumed that the surface of the filter body 1 is arranged upright in the vertical direction. The filter cleaning device 20 of the second embodiment is configured as follows: a dust box 7 is formed on one side of the direction orthogonal to the moving direction of the dust removal body 2 near the filter 1a. As a result, the dust 14 peeled off from the filter 1a by the dust removal body 2 can be accumulated in the dust box 7, and the accumulated dust 14 can be collected and discharged to the outside. The other structures are the same as those of the filter cleaning device 10 of the first embodiment, so the description is omitted.

[0039] Figure 4 30 is a perspective view showing a third embodiment of the filter cleaning device of the present invention. The filter cleaning device 30 of the third embodiment is configured as follows: a buffer device 6a is provided near the end of the support platform 4a in the long side direction, and the buffer device 6a generates a repulsive force on the dust removal body 2a when the dust removal body 2a approaches or abuts against the dust removal body 2a, thereby relieving the collision with the dust removal body 2a. Thus, even when a large inertial force is applied, the dust removal body 2a and the movable mechanism 3a can be prevented from being damaged.

[0040] In addition, the structure is as follows: a cutout portion 1c is formed between the filter frame 1b and the end of the support 4a, so that the dust collector 2a does not abut against the filter body 1. Therefore, when the dust collector 2a moves to the end of the support 4a, the resistance applied to the dust collector 2a becomes smaller, the initial movement of the dust collector becomes smooth, and the dust collector 2a can be moved vigorously, so that the dust collector 2a can exert a strong impact on the filter 1a.

[0041] Figure 5 (a) to (c) are used Figure 4 AA sections of FIG. 1 are cross-sectional views of the first to third embodiments of the shock absorbing device. Figure 5 The buffer device 6a of the first embodiment shown in (a) is formed near the two ends of the support platform 4 in the long side direction, and has insertion holes 6g, 6g formed on the side, and the convex parts 13a, 13a formed on the dust removal body 2a are inserted into the insertion holes 6g, 6g. In addition, it is configured as follows: a spring 6h as a force-applying device is provided in the insertion hole 6g, and the convex part 13a of the dust removal body 2a is rebounded if the spring 6h is pushed. Thus, even when a large inertial force is applied, it is possible to prevent the movable mechanism 3 from being damaged.

[0042] Figure 5The buffer device 6b of the second embodiment shown in (b) is formed near the two ends of the support platform 4 in the long side direction, and has insertion holes 6g, 6g formed on the side, and the convex parts 13b, 13b formed by magnets formed on the dust removal body 2b are inserted into the insertion holes 6g, 6g. In addition, it is configured as follows: a magnet 6i is provided in the insertion hole 6g, and the magnet 6i has the same magnetic pole as the opposite surface of the convex part 13b on the convex part 13b side, and the convex part 13b of the dust removal body 2b is rebounded if it approaches the magnet 6i. Thus, even when a large inertial force is applied, it is possible to prevent the movable mechanism 3 from being damaged.

[0043] Figure 5 The buffer device 6c of the third embodiment shown in (c) is formed near the two ends of the support platform 4 in the long side direction, and has insertion holes 6g, 6g formed on the side, and the convex parts 13c, 13c formed by the soft parts formed on the dust removal body 2c are inserted into the insertion holes 6g, 6g. In addition, it is configured as follows: a buffer part 6j composed of a soft part is provided in the insertion hole 6g, and if the convex part 13c of the dust removal body 2c abuts against the buffer part 6j, both are deformed to absorb the impact force. Thus, even when a large inertial force is applied, it is possible to prevent the movable mechanism 3 from being damaged.

[0044] Figure 6 : is a perspective view showing the fourth embodiment of the filter cleaning device of the present invention. In the filter cleaning device 40 of the fourth embodiment, the structure is as follows: the movable mechanism 3b has: a track-shaped support platform 4, which holds the dust removal body 2; and guide rails 5a, 5a, which are in sliding contact with the sliding contact parts 8a, 8a formed at the end of the support platform 4 and support the sliding contact parts, the support platform 4 reciprocates along the long side direction of the guide rail 5a using the inertial force generated by the acceleration, deceleration and steering of the vehicle, and the guide rail 5a is set near the end of the filter 1a, and the dust removal body 2 moves along the long side direction of the support platform 4 using the inertial force generated by the acceleration, deceleration and steering of the vehicle. In this way, the inertial force can be converted into a force along the linear direction of the filter for use.

[0045] Figure 7 (a) and (b) are perspective views showing a fifth embodiment of the filter cleaning device of the present invention. Figure 7 (a) is a diagram from the downstream side of the filter. Figure 7 (b) is a diagram from the upstream side of the filter. Figure 7(c) is a perspective view of a support platform constituting the filter cleaning device of the fifth embodiment. The filter cleaning device 50 of the fifth embodiment is configured as follows: the movable mechanism 3c includes: a rod-shaped support platform 4b, which holds the dust removal body 2d; and guide rails 5b, 5b, which are in sliding contact with the sliding contact parts 8b, 8b formed at the end of the support platform 4b and support the sliding contact parts 8b, 8b. The support platform 4b reciprocates along the long side direction of the guide rail 5b using the inertial force generated by the acceleration, deceleration and steering of the vehicle. The guide rail 5b is set near the end of the filter 1a, and the dust removal body 2d is fixed to the support platform 4b. As a result, the inertial force can be converted into a force along the linear direction of the filter 1a for use.

[0046] In the filter cleaning device 40 of the fourth embodiment and the filter cleaning device 50 of the fifth embodiment, the sliding contact portion and the guide rail are formed at both ends of the support platform, but they may be formed only at one end of the support platform, and this mode is also included in the present invention. In addition, the case where the sliding contact portion and the guide rail are formed in the approximate center of the support platform is also included in the present invention.

[0047] In the filter cleaning device 40 of the fourth embodiment and the filter cleaning device 50 of the fifth embodiment, the following structure is preferred: a buffer device is provided near the end of the guide rail in the long side direction, and the buffer device generates a repulsive force on the support platform when the support platform is close to or abuts against the support platform, thereby relieving the collision with the guide rail. Thus, even when a large inertial force is applied, damage to the movable mechanism can be prevented. In addition, the structure of the buffer device can be applied Figure 5 Since the configurations described in (a) to (c) are described above, their description will be omitted.

[0048] In the filter cleaning device 40 of the fourth embodiment and the filter cleaning device 50 of the fifth embodiment, the support platform is preferably configured such that the load per unit length in the long side direction of the support platform near the sliding contact portion supported by the guide rail is greater than the load per unit length of the support platform other than the sliding contact portion. This can increase the inertial force acting on the support platform, and can also suppress deformation of the support platform, so that the support platform can slide smoothly on the guide rail.

[0049] Figure 8 (a) and (b) are perspective views showing a sixth embodiment of the filter cleaning device of the present invention. Figure 8 (a) View from the upstream side of the filter, Figure 8 (b) View from the downstream side of the filter. Figure 8(c) is a three-dimensional view of the support platform of the filter cleaning device of the sixth embodiment. In the filter cleaning device 60 of the sixth embodiment, the structure is as follows: the movable mechanism 3d has a rod-shaped support platform 4c that holds the dust removal body 2e, one end of the support platform 4c is rotatably fixed to the rotating shaft 15 near the filter and the other end is a free end that can reciprocate, and the dust removal body 2e is fixed to the support platform 4c. In addition, the figure mark 7a is a dust collecting box for collecting dust and is a stopper member that limits the movable area of ​​the support platform 4c. In addition, the filter cleaning device of the sixth embodiment is a structure in which the dust removal body is arranged on the upstream side of the filter surface. Regardless of whether the dust removal body is arranged on the upstream side or the downstream side of the filter surface, the same effect is exerted and is included in the present invention.

[0050] Alternatively, it can be composed as follows: Figure 8 The support platform 4c and the dust removal body 2e shown in (c) are changed to Figure 6 The track-shaped support platform 4 and the roughly spherical dust collector 2 shown in the figure, the dust collector 2 uses the inertial force generated by the acceleration, deceleration and steering of the vehicle to move along the long side direction of the support platform 4, and this method is also included in the present invention. In addition, the dust collector 2e is included in the present invention as long as it is a convex component, a roughly spherical rotating body, etc., which contacts and impacts the filter 1a.

In the filter cleaning device 70 of the seventh embodiment, the following structure is adopted: the movable mechanism 3e has a support platform 4d in a substantially cover shape, the support platform 4d is arranged at a position opposite to the filter 1a across the dust removal body 2f, and has a ventilation hole 12. The dust removal body 2f freely moves along the support platform 4d by utilizing the inertial force generated by the acceleration and deceleration and steering of the vehicle. Thus, the movable mechanism 3e can be simplified, and the manufacturing cost can be reduced. Industrial Applicability
