Title: Pipe assembly for differential pressure sensor

Description:
BACKGROUND 
     1. Technical Field 
     The disclosure generally relates to pipe assemblies, especially, to a pipe assembly for a differential pressure sensor. 
     2. Description of Related Art 
     A cloud server needs to sense air pressure between opposite sides of the filtering meshwork, via a differential pressure sensor, for controlling pressure difference between the opposite sides of the filtering meshwork within a certain range. The differential pressure sensor includes two pipes located on opposite sides of the filtering meshwork to receive air. The two pipes are not secured slidably, which may effect precision of the sensed values of the differential pressure sensor. 
     Thus, there is room for improvement within the art.

     DETAILED DESCRIPTION 
     The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean at least one. 
       FIGS. 1 and 2  show one embodiment of a pipe assembly for a differential pressure sensor. The pipe assembly includes an enclosure  10  and two pipes  20  (shown in  FIG. 6 ). The two pipes  20  are used for connecting to a differential pressure sensor (not shown). 
     The enclosure  10  includes a bottom panel  11 , a first side panel  13 , two second side panels  15 , and a plane panel  17 . The two second side panels  15  are substantially parallel to each other and substantially perpendicular to the bottom panel  11 . The first side panel  13  is substantially perpendicular to the second side panel  15 . The plane panel  17  is connected between the two second side panels  15  and connected to the first side panel  13 . 
     The first side panel  13  includes a side panel body  131 , a first securing tab  133  extending from the side panel body  131 , and a second securing tab  135  extending from the side panel body  131 . The side panel body  131  perpendicularly extends from the bottom panel  11 . The first securing tab  133  defines a first securing hole  1331 . The second securing tab  135  defines a second securing hole  1351 . The side panel body  131  defines a mounting opening  1311 . The mounting opening  1311  is used for receiving a filtering meshwork (not shown). The second securing tab  135  and the first securing tab  133  are located on opposite sides of the side panel body  131 . 
     The plane panel  17  includes a plane panel body  171 , that is substantially parallel to the bottom panel  11 , and a mounting tab  173  perpendicularly extending from the plane panel body  171 . The mounting tab  173  defines two mounting holes  1731 . The plane panel body  171  defines two through holes  1711 . The plane panel body  171  is connected to the side panel body  131  of the first side panel  13 . 
     Each pipe  20  includes a pipe body  21  and an input portion  23  connected to the pipe body  21 . The pipe body  21  extends through each of the first securing hole  1331 , the second securing hole  1351 , the mounting hole  1731 , and the through hole  1711  via an elastic gasket  60 . 
       FIG. 3  shows that the elastic gasket  60  is H-shaped. The elastic gasket  60  is made of rubber. The elastic gasket  60  includes a first end portion  61 , a neck portion  62  extending from the first end portion  61 , and a second end portion  63  extending from the neck portion  62 . A through opening  64  extends through the first end portion  61 , the neck portion  62 , and the second end portion  63 . The elastic gasket  60  further includes a plurality of protrusions  65  extending from the inner surface of the through opening  64 . 
       FIGS. 4 to 7  show that in assembly, the elastic gaskets  60  are mounted in the first securing holes  1331 , the second securing holes  1351 , the mounting holes  1731 , and the through holes  1711 . The first end portion  61  and the second end portion  63  of each elastic gasket  60  are located on opposite sides of theses holes. The pipes  20  extend through the through openings  64  of the elastic gasket  60  to enable the input portions  23 , of the two pipes  20 , to be located on opposite sides of the filtering meshwork. At this time, the two input portions  23  are substantially parallel to the side panel body  131  and the bottom panel  11 . The protrusions of the elastic gaskets  60  resiliently resist the pipe bodies  21  of the two pipes  20 , thereby securing the two pipes  20  to the enclosure  10 . 
     It is to be understood, however, that even though numerous characteristics and advantages have been set forth in the foregoing description of embodiments, together with details of the structures and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
