Description

The present invention relates to a filter container holding holder and a filter container having the same.

In a pipeline for the purpose of filtering a fluid, a filter or the like is built in a part of the pipeline, and a filter container as a replacement unit that is removable and replaceable is arranged. In such a pipeline, a part of the pipeline is cut off between the end of the upstream pipeline and the end of the downstream pipeline, and the filter container is It has a structure that can be detachably attached between the end portion and the end portion of the downstream pipeline. For example, when a predetermined amount of filtration is completed, the filter container that has reached the end of its life is removed and replaced with a new filter container.

The filter container has a channel inlet and a channel outlet, and a channel is formed between the channel inlet and the channel outlet inside the filter container. A filter is arranged in the middle of the flow channel, and the filter captures particles contained in the fluid in the flow channel. Conventionally, in general, the end of the upstream pipe line and the end of the downstream pipe line are configured as a part of the manifold, and when the replacement unit is attached to the manifold, the flow path inlet of the replacement unit is The end of the upstream pipe is joined and the outlet of the flow passage is joined to the end of the downstream pipe. This completes the conduit of the flow circuit system by joining the conduit of the exchange unit to the conduit that is partially lacking.

Patent Document 1 discloses an example of a filter container that can be detached and replaced as a part of an existing pipeline. In Patent Document 1, the filter container is attached between the end of the upstream pipe line and the end of the downstream pipe line of the manifold so that the filter container is rotationally fitted around the pipe line joint portion of the filter container. Be done. In Patent Document 1, since the distance between the end of the upstream pipe and the end of the downstream pipe for attaching the filter container is unchanged, the end of the upstream pipe and the downstream The filter container, which is longer than the distance from the end of the conduit, is fitted and fixed.

On the other hand, Patent Document 2 discloses a water purifier cartridge used in a sink. Here, a filter container is inserted between the end of the upstream pipe line and the end of the downstream pipe line, and a highly rigid sleeve pipe that can slide along the flow path axis is extended to the water purifier cartridge. There is disclosed a device for fixing. That is, Patent Document 2 is an example in which the distance between the end of the upstream pipe and the end of the downstream pipe of the pipe for attaching the filter container is variable. In Patent Document 2, the end of the upstream high-rigidity pipeline is slid along the flow path axis so that the distance between the end of the upstream pipeline and the end of the downstream pipeline can be increased. While contracting, the flow path inlet and the flow path outlet of the filter container are sandwiched and fixed.

Japanese Patent No. 4723531 JP-A-3-123689

Due to different types of filter vessels, or manufacturing tolerances of the filter vessels within the same format, the lengths of the channel inlets and outlets of the filter vessels vary. Therefore, as in Patent Document 2, it is convenient if the distance between the end of the upstream pipe and the end of the downstream pipe of the pipe for mounting the filter container can be made variable. Furthermore, it would be very convenient if the end of the upstream conduit and the end of the downstream conduit could be made a flexible tube with low rigidity and flexibility. However, in order to make the end of the upstream pipe and the end of the downstream pipe a flexible tube having low rigidity and flexibility, the filter container is properly supported and its position is easy to adjust. A container holding device is required. Further, it is desirable that the holding device be easily attached and detached.

An embodiment of the present invention will be described with reference to FIG. FIG. 1 shows a filter container holding holder 1 as an embodiment of the present invention.

First, a filter container holding holder 1 according to an embodiment of the present invention will be described with reference to FIG. The filter container holding holder 1 includes a wall surface Wa (first wall surface) that extends vertically, and a wall surface Wb (second wall surface) that faces the direction opposite to the wall surface Wa and that is the back surface of the wall surface Wa and extends vertically. Is a device that is detachably attached on a base unit having. The filter container holding holder 1 includes a first contact portion 11, a second contact portion 12, and a filter container holder 13. The first contact portion 11 and the second contact portion 12 are joined by a connecting member 14. The first contact portion 11 is connected to one end of the connecting member 14, and the second contact portion 12 is connected to the other end of the connecting member 14. One end 13 a of the filter container holder 13 is connected to an arbitrary position between the first contact portion 11 and the second contact portion 12. The other end 13b of the filter container holder 13 is a weighted point. A filter container C having a weight W can be attached to the additional weight. Here, the weight is connected to the connecting member 14, but the weight may be connected to at least one of the first contact portion 11, the second contact portion 12, and the connecting member 14. In the base unit BU, the wall surface Wa corresponds to the inner surface and the wall surface Wb corresponds to the outer surface. An opening O that connects the wall surface Wa and the wall surface Wb is arranged on the base unit BU. The opening O is in the shape of a groove that penetrates between the wall surface Wa and the wall surface Wb and extends vertically. Since the connecting member 14 penetrates the opening O, the filter container holding holder 1 is attached so that the first contact portion 11 can contact the wall surface Wa and the second contact portion 12 can contact the wall surface Wb. .. The first contact portion 11 is located above the second contact portion 12.

The other end 13b of the filter container holder 13, which is a weighted point to which the weight W of the filter container C is added, causes the connecting member 14 to generate a rotation moment M around the one end 13a of the filter container holder 13. To put it the other way around, the filter container holder 13 can be arranged at a position where the rotational moment M can be generated in the connecting member 14. That is, the weighting point is arranged on the side opposite to the first contact portion 12 with respect to the second contact portion 12 and at a position apart from the second contact portion 12. The rotation moment M is a rotation moment in which the first contact portion 11 approaches the filter container C of the filter container holder 13 and the second contact portion 12 rotates away from the filter container C of the filter container holder 13. .. The rotational moment M causes the connecting member 14 to generate a pressing force Pwa for pressing the first contact portion 11 against the wall surface Wa and a pressing force Pwb for pressing the second contact portion 12 against the wall surface Wb. The wall surface Wa prevents the first contact portion 11 from dropping vertically due to a frictional force Fwa generated by the pressing force Pwa applied to the wall surface Wa. Further, the second contact portion 12 is prevented from dropping in the vertical direction due to the frictional force Fwb generated on the wall surface Wb by the pressing force Pwb against the wall surface Wb. As a result, the filter container holder 1 can hold the filter container holder 13 on the base unit having the wall surface Wa and the wall surface Wb. Further, since the filter container holding holder 1 is held by the frictional force on the wall surface Wa and the wall surface Wb of the base unit, the position of the other end 13b of the filter container holder 13 depending on the weight W of the filter container C. Can be set.

The filter container holder 13 and the connecting member 14 can be separated from each other, and the filter container holder 13 can be detachably set. It is also possible to make the filter container C and the filter container holder 13 separable. The shape of the filter container holder 13 and the connecting member 14 is not limited to the rod shape as shown in FIG. The shape is not limited as long as a rigid load path is formed between the first contact portion 11 and the second contact portion 12 and the rotational moment M can be generated.

(Example 1)
An embodiment of the present invention will be described with reference to FIGS. 2 to 5. FIG. 2 shows a filter container holding holder 5a of Example 1 corresponding to the filter container holding holder 1 of the embodiment of the invention. FIG. 3A is a cross-sectional view of the filter container holding holder 5a as viewed from the inside of the cross section of the base unit BU. FIG. 3B is a cross-sectional view of a side surface of the filter container holding holder 5a attached to the base unit BU. FIG. 4A is a cross-sectional view of an upper cross section of the filter container holding holder 5a attached to the base unit BU, and corresponds to the cross section 4A-4A in FIG. 3A. FIG. 4B is a cross-sectional view of the middle section of the filter container holding holder 5a attached to the base unit BU, and corresponds to the cross section 4B-4B in FIG. 3A. FIG. 4C is a cross-sectional view of a lower cross section of the filter container holding holder 5a attached to the base unit BU, and corresponds to the cross section 4C-4C of FIG. 3A.

The filter container holding holder 5a is detachably attached to the base unit BU. The base unit BU is typically a columnar member extending in the vertical direction. The base unit BU has a wall surface Wa that extends vertically and a wall surface Wb that is on the back side of the wall surface Wa and that faces the direction opposite to the wall surface Wa and that vertically extends. The wall surface Wa and the wall surface Wb correspond to the back surface and the front surface of the front plate BU1 (thickness t) of the base unit BU, respectively. The front plate BU1 of the base unit BU is provided with a groove-shaped opening O having a constant width D. The opening O has a groove shape extending in the vertical direction and is a communication portion that communicates with the back surface and the front surface of the front plate BU1. The opening O communicates the inside and outside of the base unit BU.

The filter container holding holder 5a includes an upper pressing portion 51, a lower pressing portion 52, a main body of the filter container holding holder 5a, and a connecting member 54. A container supporting portion 57 capable of supporting the filter container is attached to the main body of the filter container holding holder 5a on the side opposite to the connecting member 54. The container support 57 is connected to the connecting member 54 in this embodiment. The base unit BU has an elongated shape, and when the filter container holding holder 5a is attached to the base unit BU, it extends along the groove direction of the filter container holding holder 5a. The connecting member 54 is a member formed to project from the filter container holding holder 5a, and has a shape extending along the longitudinal direction of the filter container holding holder 5a. When the connecting member 54 is inserted into the opening O of the base unit BU and the filter container holding holder 5a is attached to the base unit BU, the connecting member 54 extends in the direction perpendicular to the surface of the front plate BU1 of the base unit BU. It is a member that extends inward from the outside of the unit BU and extends in the vertical direction. The upper holding portion (first contact portion) 51 is formed on one end side of the connecting member 54 in the vertical direction, and the lower holding portion (second contact portion) 52 is a connecting member on the side where the upper holding portion 51 is not formed. It is joined to the other end side of 54. When the filter container holding holder 5a is attached to the base unit BU, the container supporting portion 57 is opposite to the connecting member 54 in the direction perpendicular to the front plate BU1 of the base unit BU with respect to the main body of the filter container holding holder 5a. It is located in.

The upper pressing portion 51 is formed on the tip end side of the connecting member 54 so as to spread in a direction perpendicular to the extending direction of the connecting member 54. That is, when the connecting member 54 is inserted into the opening O of the base unit BU and the filter container holding holder 5a is attached to the base unit BU, the tip of the connecting member 54 reaches the inner surface of the base unit BU, and The pressing portion 51 is formed so as to extend from the opening O to both sides along the wall surface Wa. The upper pressing portion 51 is formed so as to extend in the vertical direction along the connecting member 54, and has a surface capable of contacting the wall surface Wa when the filter container holding holder 5a is attached to the base unit BU. Is formed in. The connecting member 54 is elastic due to the characteristics or geometrical shape of the material, and in the width direction of the groove of the opening O, the width of the upper pressing portion 51 is narrower than the width of the groove and is wider than the width of the groove. It can be deformed so that it changes. That is, in the state where the filter container holding holder 5a is attached to the base unit BU, the width d of the connecting member 54 in the width direction of the groove of the opening O is smaller than the width D of the groove, and the width d of the opening O in the width direction of the groove of the opening O is small. The width of the upper pressing portion 51 is larger than the width D of the groove. In the filter container holding holder 5a, at least the upper pressing portion 51 and the connecting member 54 are made of an elastic material as a material characteristic. For example, the connecting member 54 is two elastic connecting member claws 54a and 54b that can be inserted into the opening O and are spaced apart, and the distance between them can be adjusted. Can be configured to be. That is, the connecting member 54 is divided into a connecting member claw 54a and a connecting member claw 54b, and the upper pressing part 51 is divided into a first contact part claw 51a and a first contact part claw 51b. The first contact portion claw 51a is a direction in which the connecting member claw 54a is out of the plane of the front plate BU1 of the base unit BU and extends away from the opening O along the wall surface Wa at the tip extending toward the inside of the base unit BU. Is sticking out. The first contact portion claw 51b is a direction in which the connecting member claw 54b is an out-of-plane direction of the front plate BU1 of the base unit BU, and a direction extending away from the opening O along the wall surface Wa at the tip extending toward the inside of the base unit BU. Is sticking out. As a result, the connecting member claws 54a and the connecting member claws 54b bend each other to provide geometrical elasticity. Due to the elasticity generated from the characteristic of the geometrical shape, the upper pressing portion 51 reduces the width of the connecting member 54 in the width direction of the groove of the opening O when the filter container holding holder 5a is attached to the base unit BU, and thereby The width of the upper pressing portion 51 is smaller than the width D of the groove and is inserted into the opening O of the connecting member 54.

When the filter container holding holder 5a is attached to the base unit BU, the lower pressing portion 52 extends along the longitudinal direction of the main body of the filter container holding holder 5a and along the direction in which the opening O extends. The filter container holding holder 5a is formed on the opposite side of the base unit BU and has a surface that can contact the wall surface Wb when the filter container holding holder 5a is attached to the base unit BU. That is, when the filter container holding holder 5a is attached to the base unit BU, the upper holding portion 51 and the lower holding portion 52 are the lower holding portion facing the wall surface Wa and the surface of the upper holding portion 51 facing the wall surface Wa. It is formed so as to be parallel to the surface of 52.

The surface distance between the surface of the upper pressing portion 51 facing the wall surface Wa and the surface of the lower pressing portion 52 facing the wall surface Wb is the surface distance between the wall surface Wa and the wall surface Wb, that is, almost the thickness of the front plate BU1 of the base unit BU. It is formed to have a thickness t. In the state where the width d of the connecting member 54 is returned to the original position and the upper pressing portion 51 is housed inside the base unit BU, and the filter container holding holder 5a is attached to the base unit BU, the upper pressing portion 51 facing the wall surface Wa. The front plate BU1 of the base unit BU is sandwiched by the surface of the lower pressing portion 52 facing the wall surface Wb.

The filter container C is attached to the filter container fixture 59 and attached to the container support portion 57. The filter container fixture 59 has an arm 58 that holds the filter container C in between. The filter container fixture 59 has a mounting rod 59a extending in the axial direction of the filter container C. The filter container C sandwiched by the arms 58 is inserted into the container support portion 57 by the attachment rod 59a of the filter container fixture 59 and attached to the filter container holding holder 5a. When the filter container C is held by the filter container fixture 59 and the mounting rod 59b of the filter container fixture 59 is inserted into the container support portion 57, the weight W of the filter container C is added to the force point E, which is the force point. It

At this time, when the weight of the filter container C is added to the weighted point, the weighted point becomes the power point E, the lower side F portion of the lower holding portion 52 serves as the fulcrum, and the upper holding portion 51 becomes the action point A. A rotation moment is applied about the fulcrum of the lower F portion of the holding portion 52, the upper holding portion 51 pushes the inner wall surface Wa of the base unit BU, and the lower holding portion 52 pushes the wall surface Wb of the base unit BU to hold the filter container holding holder. 5a is fixed to the base unit BU. Generally, if the lengths of the upper pressing portion 51 and the lower pressing portion 52 in the direction in which the connecting member 54 extends are increased, the area of the upper pressing portion 51 that presses the wall surface Wa and the lower pressing portion 52 that presses the wall surface Wb. The area is increased, and the fixing force for attaching the filter container holding holder 5a to the base unit BU is increased.

In a state where the filter container holding holder 5a is attached to the base unit BU, the upper holding portion 51 is narrower than the groove width D of the opening portion on the lower holding portion 52 side along the direction in which the opening O extends. It has a tapered portion 53 having a tapered shape. That is, the first contact portion claw 51a and the first contact portion claw 51b have tapered portions 53a and 53b each having a shape that becomes narrower along the direction in which the opening O extends toward the lower pressing portion 52 side. is doing. The width of the tip of the tapered portion 53 in the groove width direction of the opening O, that is, the width of the tapered portions 53a and 53b is smaller than the width D of the opening O. For example, as in the present embodiment, the length of the lower holding portion 52 in the direction in which the opening O extends is shorter than the length of the connecting member 54, and the upper holding portion in the extending direction of the connecting member 54. The lower pressing part 52 is arranged so that the position 51 is not located.

In the state where the filter container holding holder 5a is attached to the base unit BU, the positions of the tapered portions 53a and 53b are located on the lower holding portion 52 side of the upper holding portion 51 along the direction in which the opening O extends. To do so. Further, the upper pressing portion 51 is formed to have a surface that comes into contact with the wall surface Wa when the filter container holding holder 5a is attached to the base unit BU, but at the position where the tapered portions 53a and 53b are arranged. It has an escape portion 55 that gradually separates from the wall surface Wa in the direction perpendicular to the wall surface Wa in the direction in which the tapered portions 53a and 53b become thinner. The fulcrum portion 52a and the escape portion 55 function when the filter container holding holder 5a is removed. An edge portion of the lower pressing portion 52 on the side of the tapered portions 53a and 53b, which is in contact with the wall surface Wb, is a fulcrum portion 52a. As a result, when the filter container holding holder 5a is tilted with the edge portion of the lower holding portion 52 as the fulcrum portion 52a, the surface of the upper holding portion 51 that was in contact with the wall surface Wa when attached to the base unit BU is the escape portion 55. It is possible to lean. If the distance between the positions of the tapered portions 53a and 53b in the groove width direction of the opening O and the fulcrum portion 52a is set to be long, the tapered tapered portion 53 can be easily led out from the opening O, and the filter container holding holder 5a can be removed. In addition to facilitating tilting, the filter container holding holder 5a is easily removed from the base unit BU.

The fulcrum portion 52a is a portion where the filter container holding holder 5a comes into contact with the wall surface Wb side of the front plate BU1 of the base unit BU when the filter container holding holder 5a is inclined in such a direction that the tapered portion 53 comes out of the opening O. is there. Typically, it is advantageous to take the fulcrum portion 52a at the edge portion of the lower pressing portion 52, but the fulcrum portion 52a is not limited to the edge portion of the lower pressing portion 52, but in the direction in which the connecting member 54 extends. It can be placed at any position. When the fulcrum portion 52a serves as the fulcrum F and a force for removing the filter container holding holder 5a is applied to the lower side of the filter container holding holder 5a, the entire part thereof becomes the power point E and the lower part of the tapered portion 53 becomes the action point A. A force that reduces the width d of the connecting member 54 is applied. At this time, when the point of action A moves to the upper portion of the tapered portion 53, the tapered portion causes a force that pulls out the upper pressing portion 51 and the connecting member 54 from the opening O. As a result, when the position of the force point is adjusted while inclining the filter container holding holder 5a, the filter container holding holder 5a comes into contact with the wall surface Wb side of the front plate BU1 of the base unit BU, and with that point as a fulcrum, among the upper holding portions 51. , Tapered portions 53a, 53b are first led out from the opening O. When the tip angles of the tapered tapered portions 53a and 53b are narrowed, that is, when the length of the tapered portions 53a and 53b in the direction in which the connecting member 54 extends is increased, the tapered portions 53a and 53b can be easily opened from the opening O. The filter container holding holder 5a can be easily removed from the base unit BU. Since the vertical positions of the tapered portions 53a and 53b are the action points A, they are set above the fulcrum portion 52a which is the fulcrum F.

Next, with reference to FIGS. 4A to 4C and FIG. 5, how to attach/detach the filter container holding holder 5a to/from the base unit BU will be described. First, when attaching the filter container holding holder 5 a to the base unit BU, the connecting member claw 54 a and the connecting member claw 54 b, which are the connecting members 54 of the filter container holding holder 5 a, are inserted into the opening O, and the upper pressing portion 51 is used. A certain first contact portion claw 51a and a certain first contact portion claw 51b are pushed into the inside of the base unit BU from the outside of the front plate BU1 of the base unit BU through the groove-shaped opening O. Then, the widths of the connecting member claws 54a and the connecting member claws 54b are reduced, so that the widths of the first contact portion claws 51a and the first contact portion claws 51b become smaller than the width D of the opening O, and the upper pressing is performed. The portion 51 pushes into the inside of the base unit BU through the opening O. After entering the inside of the base unit BU, the widths of the first contact part claws 51a and the first contact part claws 51b of the upper pressing part 51 are restored, and the weight of the filter container C is added to the container support part 57. The front pressing plate 51 of the base unit BU is sandwiched between the upper pressing part 51 and the lower pressing part 52, and the rotational moment M is generated, so that the filter container holding holder 5a is attached to the base unit BU.

The rotational moment M is a rotational moment M in a direction in which the upper pressing portion 51 approaches the weighted point of the weight W of the filter container C and the lower pressing portion 52 rotates in a direction away from the weighted point of the filter container C. The rotational moment M causes the connecting member 54 to generate a force that presses the upper pressing portion 51 against the wall surface Wa and a force that presses the lower pressing portion 52 against the wall surface Wb. It prevents the upper pressing portion 51 from dropping in the vertical direction due to a frictional force generated on the wall surface Wa due to the pressing force applied to the wall surface Wa. Further, the lower pressing portion 52 is prevented from dropping in the vertical direction due to a frictional force generated on the wall surface Wb due to the pressing force applied to the wall surface Wb.

When the filter container holding holder 5a is tilted with respect to the front plate BU1 of the base unit BU so that the lower pressing portion 52 of the filter container holding holder 5a is separated from the wall surface Wb, the fulcrum portion 52a of the front plate BU1 of the base unit BU is formed. It contacts the wall surface Wb. Here, when the tapered portion 53 of the upper pressing portion 51 is pulled out from the opening O around the fulcrum portion 52a with the lower pressing portion 52 as an action point, the first contact portion which is the upper pressing portion 51 of the upper pressing portion 51. The claws 51a and the first contact part claws 51b gradually push into the openings O from the tapered portions 53a and 53b, and the elasticity of the upper pressing parts 51 is reduced so that the width d becomes the width D of the openings O. The upper pressing portion 51 is pulled out from the opening O. That is, by tilting the filter container holding holder 5a with respect to the resistance force generated in the upper pressing portion 51 when the upper pressing portion 51 is pulled out from the opening O, the location where the fulcrum portion 52a contacts the wall surface Wb is the fulcrum. By the pulling force amplified by the lever principle, the width of the opening O of the upper pressing portion 51 in the groove width direction becomes smaller than the width of the opening O due to its elasticity, and it is possible to easily pull out.

(Example 2)
Example 2 will be described as an example of another mode with reference to FIG. 6A. FIG. 6A shows a filter container holding holder 5b in Example 2 corresponding to the embodiment of the invention. In the first embodiment, the filter container holding holder 5a and the filter container fixture 59 are separated. On the other hand, in the filter container holding holder 5b of the second embodiment, the filter container holding holder 5a and the filter container fixture 59 are integrated. Here, only the different parts will be described. In other parts, the filter container holding holder 5a of the first embodiment and the filter container holding holder 5b of the second embodiment are the same. That is, in the second embodiment, the arm 58 for holding the filter container C is directly attached to the filter container holding holder 5a of the first embodiment. As a result, the filter container C can be fixed to the filter container holding holder 5b without the filter container fixture 59.

(Example 3)
Example 3 will be described as an example of another mode with reference to FIG. 6B. FIG. 6B shows a filter container holding holder 5c in Example 3 corresponding to the embodiment of the invention. In the first embodiment, the filter container fixture 59 and the filter container C are separated. On the other hand, in the third embodiment, the filter container C is integrated with the filter container holding holder 5c. Here, only the different parts will be described. In other parts, the filter container holding holder 5a of the first embodiment and the filter container holding holder 5c of the third embodiment are the same. That is, in the third embodiment, the outer surface of the filter container C is directly formed integrally with the filter container holding holder 5a in the first embodiment. As a result, the filter container C can be directly attached to and detached from the base unit BU without using the filter container fixture 59.

Example 4 will be described as an example of another mode with reference to FIG. 6C. FIG. 6C shows a filter container holding holder 6 in Example 4 corresponding to the embodiment of the invention. In Examples 1 to 3, the connecting member 54 is divided into the connecting member claw 54a and the connecting member claw 54b, and the upper pressing part 51 is divided into the first contact part claw 51a and the first contact part claw 51b. The width in the groove width direction of each opening O of the connecting member 54 and the upper pressing portion 51 can be changed. On the other hand, in the fourth embodiment, the connecting member 54 is not divided into the connecting member claw 54a and the connecting member claw 54b, and the upper pressing part 51 is not divided into the first contact part claw 51a and the first contact part claw 51b. This is an example in which the upper pressing portion 51 and the connecting member 54 are integrated. By making the material of the upper pressing portion 51 and the connecting member 54 a material having a strong elastic force, the widths of the openings O of the connecting member 54 and the upper pressing portion 51 in the groove width direction are changed depending on the characteristics of the material. It is possible. The connecting member 54 and the upper pressing portion 51 function as in the first embodiment.

(Example 5)
A filter container holding holder 7, which is another embodiment 5, will be described with reference to FIGS. 7 and 8. The filter container holding holder 7 of the fifth embodiment has a configuration in which a plurality of filter container holding holders 7 can be used in combination. FIG. 7 is a diagram in which two filter container holding holders 7 are connected and attached to the base unit BU. FIG. 8 is a view showing a cross section 8-8 of FIG. 7. The filter container holding holder 7 is the same as the filter container holding holder 5a of the first embodiment except that it has a coupling portion 56. Here, the points different from the first embodiment will be described. The filter container holding holder 7 includes a rod-shaped member 56a projecting from one end of the filter container holding holder 7 on the side of the upper pressing portion 51 and a receiving member 56b capable of receiving a rod-shaped member having the same shape as the rod-shaped member. 7 on the other end side. The one filter container holding holder 7 receives the rod-shaped member 56a of the other filter container holding holder 7 (the same shape as the rod-shaped member of the one filter container holding holder 7) by the receiving member 56b of the one filter container holding holder 7. By doing so, the point that it can be connected to another filter container holding holder 7 is different.

That is, the filter container holding holder 7 is different in that it has the rod-shaped member 56a and the receiving member 56b as the connecting portion 56. The rod-shaped member 56a is included in the upper pressing portion 51 along the longitudinal direction of the main body of the filter container holding holder 7, that is, along the direction in which the opening O extends when the filter container holding holder 7 is attached to the base unit BU. The tapered portions 53a and 53b are formed so as to extend from the end portion on the side where the tapered portions 53a and 53b are not arranged. The receiving member 56b has substantially the same size as the cross-sectional size of the rod-shaped member 56a, can receive the rod-shaped member 56a in a detachable manner, and is arranged on the side opposite to the end on the side where the rod-shaped member 56a projects. ing. At least two filter container holding holders 7 can be connected, and when two filter container holding holders 7 are connected, that is, one receiving member 56b on the side of the lower holding portion 52 of the filter container holding holder 7 is connected to the other. When the rod-shaped member 56a arranged on the side of the upper pressing portion 51 of the filter container holding holder 7 is inserted and connected, the receiving member 56b of the one filter container holding holder 7 becomes the rod-shaped member 56a of the other filter container holding holder 7. Can be received and combined. On the contrary, when the rod-shaped member 56a of the other filter container holding holder 7 is pulled out from the receiving member 56b of the one filter container holding holder 7, it can be separated.

When connecting so that the rod-shaped member 56a of the other filter container holding holder 7 is inserted into the receiving member 56b side of the one filter container holding holder 7, the rod-shaped member 56a of the filter container holding holder 7 is A load is applied so that the filter container holding holder 7 is separated from the base unit BU via the receiving member 56b into which is inserted. As a result, when the filter container holding holder 7 is attached to the base unit BU, the lower filter container holding holder 7 is fixed to the base unit BU by the same mechanism as in the first embodiment, and the upper filter container holding holder 7 is attached. Also, since it is fixed to the base unit BU by the same mechanism as in the first embodiment, in the two connected filter container holding holders 7, the upper holding part 51 and the lower holding part 52 have one filter in the case of the first embodiment. A force twice as much as that applied to the container holding holder 5a is applied, the overall rotation moment M applied to the two filter container holding holders 7 is increased, and one filter container holding holder 5a falls in the vertical direction. It can be made to function so as to increase the frictional force that prevents this, and so to speak, it will have a function as a stopper.

Here, in the filter container holding holder 7, the rod-shaped member 56a projects from the upper holding part 51 side which is one end side of the filter container holding holder 7 side of the upper holding part 51 side, and the other end side of the filter container holding holder 7 The example in which the receiving member 56b is arranged on the side of the certain lower pressing portion 52 has been described. However, this can be reversed. That is, the receiving member 56b is arranged on the side of the upper pressing part 51 which is one end of the filter container holding holder 7, and the rod-shaped member 56a projects from the side of the lower pressing part 52 which is the other end of the filter container holding holder 7. It may be arranged to do so. That is, if the rod-shaped member 56a on the lower holding portion 52 side of the other filter container holding holder 7 is inserted into the receiving member 56b on the upper holding portion 51 side of the one filter container holding holder 7, the same as in the above example. Then, the receiving member 56b of the one filter container holding holder 7 receives and joins the rod-shaped member 56a of the other filter container holding holder 7. On the contrary, if the rod-shaped member 56a of the other filter container holding holder 7 is separated from the receiving member 56b of the one filter container holding holder 7 by pulling out, the same effect is obtained. At least two or more filter container holding holders 7 can be configured to be separable and connectable.
