Figure 5 This is a schematic diagram of a side-mounted filter cartridge housing fixed to a filter cartridge housing storage device.

[0033] Please refer to this first. Figure 1 , Figure 2 and Figure 3 The filter cartridge housing 100 is suitable for housing multiple filter cartridges F (drawn in...). Figure 4 and Figure 5The filter cartridge housing device 100 includes a first desktop 110 and a second desktop 120. The first desktop 110 includes a first top plate portion 111, a first side plate portion 112, and a first side plate portion 113, with the first side plate portions 112 and 113 connected to the first top plate portion 111 and facing each other. The first desktop 110 has a first assembly opening O1 formed by the first top plate portion 111, the first side plate portion 112, and the first side plate portion 113. The first top plate portion 111 and each of the first side plate portions 112 and 113 respectively have first filter cartridge housing fixing holes H1 and H2, that is, the first top plate portion 111 has a first filter cartridge housing fixing hole H1, and the first side plate portions 112 and 113 respectively have a first filter cartridge housing fixing hole H2. The first filter cartridge housing fixing holes H1 and H2 are suitable for fixing the filter cartridge housing F. The second desktop 120 includes a second top plate portion 121, a second side plate portion 122, and a second side plate portion 123 (drawn on...). Figure 3 The second side plate portions 122 and 123 are connected to the second top plate portion 121 and are opposite to each other. The second top plate portion 121, the second side plate portion 122, and the second side plate portion 123 form the first insertion side P1 corresponding to the first assembly port O1. The second top plate portion 121 and each of the second side plate portions 122 and 123 respectively have second filter element housing fixing holes H3 and H4, that is, the second top plate portion 121 has a second filter element housing fixing hole H3, and the second side plate portions 122 and 123 respectively have a second filter element housing fixing hole H4. The second filter element housing fixing holes H3 and H4 are suitable for fixing the filter element housing F. The first insertion side P1 is adapted to extend into the first assembly port O1, such that the first top plate portion 111 overlaps the second top plate portion 121, and the first side plate portions 112 and 113 respectively overlap the second side plate portions 122 and 123; for example, the first side plate portion 112 overlaps the second side plate portion 122, and the first side plate portion 113 overlaps the second side plate portion 123. The second tabletop 120 is adapted to move relative to the first tabletop 110.

[0034] Please refer to Figure 2 , Figure 4 and Figure 5 The first side plates 112 and 113 of the first desktop 110 can be bent relative to the first top plate 111, wherein the first filter housing fixing hole H1 of the first top plate 111 can accommodate a vertical filter housing F1 (drawn in...). Figure 4 The first filter housing fixing hole H2 of the first side plate 112 and 113 can accommodate the side-mounted filter housing F2 (drawn in...). Figure 5The first filter housing fixing holes H1 and H2 can have different shapes and sizes. For example, in this embodiment, the first filter housing fixing holes H1 can be generally circular, and approximately five first filter housing fixing holes H1 are used to fix one upright filter housing F1. On the other hand, the first filter housing fixing holes H2 can be generally elliptical, and approximately four first filter housing fixing holes H2 are used to fix one side-mounted filter housing F2. The first side plate portions 112 and 113 can be generally perpendicular to the first top plate portion 111, but the present invention is not limited thereto. Incidentally, the material of the first desktop 110 in this embodiment may include metal, but the present invention does not impose any restrictions on this.

[0035] Please refer to this again. Figure 1 , Figure 2 and Figure 3 In this embodiment, the features of the second desktop 120 are substantially the same as those of the first desktop 110, that is, the features of the second top plate portion 121 are the same as those of the first top plate portion 111, and the features of the second side plate portions 122 and 123 are the same as those of the first side plate portions 112 and 113. Similarly, the second filter cartridge fixing hole H3 of the second top plate portion 121 can accommodate an upright filter cartridge housing F1 (drawn in...). Figure 4 The second filter housing fixing holes H4 of the second side plate portions 122 and 123 can accommodate the side-mounted filter housing F2 (drawn in...). Figure 5 The second desktop 120 extends into the first assembly port O1 of the first desktop 110, aligning the first filter housing fixing hole H1 with the second filter housing fixing hole H3, and the first filter housing fixing hole H2 with the second filter housing fixing hole H4. Specifically, the aligned first filter housing fixing holes H1 and H3 can be used to fix a vertical filter housing F1, while the aligned first filter housing fixing holes H2 and H4 can be used to fix a side-mounted filter housing F2. Thus, the assembled first desktop 110 and second desktop 120 not only reduce the volume of the filter housing storage device 100 to minimize space occupation, but also fully utilize the overlapping portion of the first desktop 110 and second desktop 120 to fix the filter housing F, thereby further improving the space utilization rate of the filter housing storage device 100.

[0036] Please continue to refer to this. Figure 2 and Figure 3 In this embodiment, in the direction X from the first side panel 112 to the first side panel 113, the width of the first assembly opening O1 of the first desktop 110 is W1 (marked as...). Figure 3 In the direction X from the second side panel 122 to the second side panel 123, the width of the first insertion side P1 of the second desktop 120 is W2 (marked as follows). Figure 3The width W1 is greater than W2, making it easier for the first insertion side P1 to extend into the first assembly port O1. Furthermore, the width W1 is, for example, the distance between the first side panels 112 and 113 in the X direction. On the other hand, the second side panels 122 and 123 each have outer surfaces OS1 and OS2 facing away from each other, i.e., the second side panel 122 has an outer surface OS1, and the second side panel 123 has an outer surface OS2. The width W2 is, for example, the distance between the outer surfaces OS1 and OS2 in the X direction. Incidentally, after the second desktop 120 is assembled to the first desktop 110, the first top panel 111 can fit against the second top panel 121, the first side panel 112 can be slightly separated from the second side panel 122, and the first side panel 113 can be slightly separated from the second side panel 123, to allow space for the second desktop 120 to move easily relative to the first desktop 110.

[0037] Compared to existing technologies, the filter cartridge housing storage device 100 of this embodiment employs a first desktop 110 and a second desktop 120. The first top plate 111 of the first desktop 110 and the second top plate 121 of the second desktop 120 can be used to fix upright filter cartridges F1, while the first side plate 112, the first side plate 113, the second side plate 122, and the second side plate 123 can be used to fix side-mounted filter cartridges F2. Furthermore, the second desktop 120 can retract and move relative to the first desktop 110, thereby reducing the volume of the filter cartridge housing storage device 100 when the number of stored filter cartridges F is small, thus reducing the space occupied. Based on the above, the filter cartridge housing storage device 100 of this embodiment can effectively utilize space to store filter cartridges F of different specifications.

[0038] Please refer to this again. Figure 1 and Figure 2The filter cartridge housing 100 may further include two table leg elements 130, which are respectively fixed to the first tabletop 110 and the second tabletop 120. The two table leg elements 130 extend, for example, along a direction Y, which may be approximately perpendicular to the first top plate portion 111 and the second top plate portion 121. The two table leg elements 130 may include a first table leg element 131 and a second table leg element 132. The first table leg element 131 is fixed to the first top plate portion 111 and away from the first assembly opening O1, and the second table leg element 132 is fixed to the second top plate portion 121 and away from the first insertion side P1. This increases the distance between the first table leg element 131 and the second table leg element 132. Therefore, to further reduce the volume of the filter cartridge housing 100, the second tabletop 120 can be extended as far as possible into the first tabletop 110. Furthermore, the filter cartridge housing storage device 100 may also include a third table leg element 140, wherein the third table leg element 140 is fixed to the second top plate portion 121 and close to the first insertion side P1, so that the filter cartridge housing storage device 100 stands more stably. Incidentally, after the second tabletop 120 is assembled to the first tabletop 110, the third table leg element 140 is located between the two table leg elements 130. It is understood that in other embodiments, the filter cartridge housing storage device 100 may not be provided with table leg elements 130, and the filter cartridge housing storage device 100 may be hung on the wall or placed on the ground, while this utility model does not impose many restrictions on the placement method of the filter cartridge housing storage device 100.

[0039] Incidentally, in this embodiment, the first desktop 110 also includes, for example, a first end plate portion 114 (drawn on...). Figure 2 The first end plate portion 114 connects to the first top plate portion 111, the first side plate portion 112, and the first side plate portion 113, and is opposite to the first assembly port O1. The second desktop 120 further includes a second end plate portion 124. The second end plate portion 124 connects to the second top plate portion 121 and the second side plate portions 122 and 123, and is opposite to the first insertion side P1. The first end plate portion 114 and the second end plate portion 124 respectively have handle structures G1 and G2; in other words, the first end plate portion 114 has a handle structure G1, and the second end plate portion 124 has a handle structure G2. Therefore, the first desktop 110 and the second desktop 120 can be moved more easily via the handle structures G1 and G2. In this embodiment, each handle structure G1 and G2 includes, for example, a perforation, so as not to occupy any additional space.

[0040] Figure 6 This is a schematic diagram of a filter cartridge housing storage device according to another embodiment of the present invention. Figure 7 yes Figure 6 A cross-sectional view along section line A2-A2. The structure and advantages of the filter cartridge housing device 100a in this embodiment are similar to those of... Figure 2 The following describes only the differences in the embodiments. Please refer to... Figure 6 and Figure 7The first desktop 110a may further include a first track structure 115. The first side panels 112 and 113 have inner surfaces IS1 and IS2 on their respective sides facing each other; that is, the first side panel 112 has an inner surface IS1, and the first side panel 113 has an inner surface IS2. The first track structure 115 is fixed to one of the inner surfaces IS1 and IS2, and this embodiment exemplifies this by fixing two first track structures 115 to the inner surfaces IS1 and IS2 respectively. The second desktop 120a may also include, for example, a second track structure 125 corresponding to the first track structure 115. The first track structure 115 and the second track structure 125 are adapted to abut against each other when the second desktop 120a extends into the first assembly opening. Therefore, the second desktop 120a can be more easily aligned and assembled to the first desktop 110a via the second track structure 125 provided by the first track structure 115, and the first desktop 110a and the second desktop 120a can move more stably relative to each other.

[0041] In detail, the first track structure 115 may have a first piece 1151, a second piece 1152, and a third piece 1153, wherein the third piece 1153 is fixed to the first side plate portion 113 and opposite to the first piece 1151, and the second piece 1152 connects the first piece 1151 and the third piece 1153. Similarly, the second track structure 125 may have a fourth piece 1251, a fifth piece 1252, and a sixth piece 1253, wherein the sixth piece 1253 is fixed to the second side plate portion 123 and opposite to the fourth piece 1251, and the fifth piece 1252 connects the fourth piece 1251 and the sixth piece 1253. The first piece 1151 can extend between the fourth piece 1251 and the sixth piece 1253 and abut against the fifth piece 1252. Similarly, the fourth piece 1251 can extend between the first piece 1151 and the third piece 1153, and abut against the second piece 1152.

[0042] In this embodiment, the number of first track structures 115 may include two, and the two first track structures 115 are respectively fixed to the inner surfaces IS1 and IS2. The number of second track structures 125 may also include two. The two second track structures 125 are respectively fixed to the outer surfaces OS1 and OS2. The two first track structures 115 are adapted to abut against the two second track structures 125 when the second desktop 120a extends into the first assembly port O1. Therefore, through the first track structures 115 and the second track structures 125, the second desktop 120a can be more easily aligned and assembled to the first desktop 110a, and can also move more stably relative to the first desktop 110a. In one embodiment, the number of first track structures 115 and second track structures 125 may each be more than two, but this utility model does not impose any restrictions on this. Please continue to refer to Figure 7In this embodiment, the filter cartridge housing device 100a may further include a plurality of wheel structures 150, wherein the wheel structures 150 abut against the first track structure 115 and the second track structure 125, so that the first tabletop 110a and the second tabletop 120a can move relative to each other more easily. For example, the wheel structure 150 may abut between the second sheet 1152 and the fifth sheet 1252.

[0043] Figure 8 This is a schematic diagram of a filter cartridge housing storage device according to another embodiment of the present invention. Figure 9 yes Figure 8 A cross-sectional view showing the locking assembly securing the first and second desktops. The structure and advantages of the filter cartridge housing device 100b in this embodiment are similar to those of other devices. Figure 2 The following describes only the differences in the embodiments. Please refer to... Figure 8 and Figure 9 The filter cartridge housing device 100b further includes, for example, a locking assembly 160, which includes a body 161 and a pin 162. The body 161 includes a base 1611 and an aligning member 1612. The base 1611 is disposed on one of the first side plate portions 112 and 113, with the first side plate portion 112 being used as an example in this embodiment. The aligning member 1612 is pivotally connected to the base 1611 and has an aligning hole H. The aligning hole H is adapted to align with one of the overlapping first filter cartridge housing fixing holes H2 and one of the overlapping second filter cartridge housing fixing holes H4, and the pin 162 is adapted to pass through the aligning hole H and the overlapping first filter cartridge housing fixing holes H2 and H4.

[0044] For example, the alignment hole H overlaps with one of the first filter housing fixing holes H2 of the first side plate portion 112 and one of the second filter housing fixing holes H4 of the second side plate portion 122, and the pin 162 can pass through the overlapping alignment hole H, the first filter housing fixing hole H2, and the second filter housing fixing hole H4. Thus, the first tabletop 110 and the second tabletop 120 can be fixed to each other via the locking assembly 160. In this embodiment, the alignment member 1612 is, for example, pivotally connected to the base 1611, and the alignment member 1612 can rotate relative to the base 1611 in the direction R, so that the alignment hole H overlaps with the first filter housing fixing hole H2 and the second filter housing fixing hole H4. Incidentally, the base 1611 of the body 161 can be fixed to the outer surface OS of the first side plate portion 112. The filter housing storage device 100b of this embodiment includes, for example, one locking assembly 160, but the present invention does not impose any limitation on the number of locking assemblies 160.

[0045] Figure 10 This is a schematic diagram of a filter cartridge housing storage device according to another embodiment of the present invention. Figure 11 yes Figure 10 Cross-sectional view along section line A3-A3. The structure and advantages of the filter cartridge housing device 100c in this embodiment are similar to those of... Figure 2 The following describes only the differences in the embodiments. Please refer to... Figure 10 and Figure 11 The filter cartridge housing 100c may further include a third tabletop 170, wherein the third tabletop 170 includes a third top plate portion 171, a third side plate portion 172 and a third side plate portion 173 (drawn in...). Figure 11 The third side panels 172 and 173 are connected to the third top panel 171 and are opposite to each other. The third desktop 170 has a second insertion side P2 and a second assembly port O2, and the third top panel 171, the third side panels 172 and 173 surround the second assembly port O2. The second insertion side P2 is adapted to extend into the first assembly port O1 of the first desktop 110, and the second assembly port O2 is adapted to allow the first insertion side P1 of the second desktop 120 to extend into. The third top panel 171 and each of the third side panels 172 and 173 respectively have third filter housing fixing holes H5 and H6, that is, the third top panel 171 has a third filter housing fixing hole H5, and the third side panels 172 and 173 respectively have third filter housing fixing holes H6. The third desktop 170 is adapted to move relative to the first desktop 110 and the second desktop 120.

[0046] Therefore, the filter cartridge housing device 100c can accommodate more filter cartridges via the third tabletop 170. Specifically, on the side of the third tabletop 170 near the second insertion side P2, a portion of the third filter cartridge fixing hole H5 in the third top plate portion 171 can be aligned with the first filter cartridge fixing hole H1 located in the first top plate portion 111; a portion of the third filter cartridge fixing hole H6 in the third side plate portion 172 can be aligned with the first filter cartridge fixing hole H2 located in the first side plate portion 112; and a portion of the third filter cartridge fixing hole H6 in the third side plate portion 173 can be aligned with the first filter cartridge fixing hole H2 located in the first side plate portion 113. Similarly, on the side of the third tabletop 170 near the second assembly port O2, a portion of the third filter cartridge fixing hole H5, for example, can be aligned with the second filter cartridge fixing hole H3, and a portion of the third filter cartridge fixing hole H6 can be aligned with the second filter cartridge fixing hole H4.

[0047] In this embodiment, in the direction X from one of the third side panel portions 172 to the other third side panel portion 173, the width of the second insertion side P2 of the third desktop 170 is W3, and the width of the second assembly port O2 is W4. W1>W3, and W4>W2. This allows the first insertion side P1 to easily extend into the second assembly port O2, and the second insertion side P2 to easily extend into the first assembly port O1. Specifically, the third side panel portion 172 may have an outer surface OS3, and the third side panel portion 173 may have an outer surface OS4 facing away from the outer surface OS3. The width W3 may be the distance between the outer surfaces OS3 and OS4 in the direction X, and the width W4 may be the width of the second assembly port O2 in the direction X. Similarly, the third side panel 172 may be slightly separated from the first side panel 112 and the second side panel 122, and the third side panel 173 may be slightly separated from the first side panel 113 and the second side panel 123, so as to reserve space for the third tabletop 170 to move relative to the first tabletop 110 and the second tabletop 120.
