     It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts have been exaggerated to better illustrate details and features of the present disclosure. 
     Several definitions that apply throughout this disclosure will now be presented. 
     The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
     The present disclosure is relation to a cleansing device used to purify waste gas in cutting processes. 
       FIG. 1  illustrates a cleansing device  100  including a housing  10 , a fan  30 , and a circulation module  90 . The fan  30  and the circulation module  90  can be mounted on the housing  10 . 
     The housing  10  can be hollow and substantially rectangular, and define an air inlet  112  in a side wall, an exhaust vent  115  on a top surface, and a storage container  117  on a bottom surface. External waste gas flows into the cleansing device  100  through the air inlet  112 , and clean gas flows out of the cleansing device  100  through the exhaust vent  115 . 
     The storage container  117  can be positioned opposite to the exhaust vent  115  and can be substantially funnel-shaped in that the side walls slope so that the lower portion is narrower than the upper portion. The storage container  117  can be used to receive water for spraying the waste gas, and residues in the water can be gathered or collected in the storage container  117 . The bottom of the storage container  117  can define a drain pipe  1171  for removing the residues in the water. 
     The fan  30  can be mounted on the housing  10  corresponding to the air inlet  112 . The fan  30  can rotate relative to the housing  10 , configured to lead the external waste gas quickly flowing into the cleansing device  100 . 
     The circulation module  90  can include a water tank  91  and a water pump  93 , which in this example are mounted on two opposite side walls of the housing  10 , but can be mounted in other configurations. The circulation module  90  can supply water to the cleansing device  100 . 
       FIG. 2  illustrates that the cleansing device  100  can further include a receiving portion  110  in the housing  100 , two support members  20 , a filter  50 , and a spraying module  70  received in the receiving portion  110 . 
     The receiving portion  110  can be separated into a waste gas receiving portion  1101  and a fresh gas exhausting portion  1103  by the filter  50 . The fan  30  can be positioned on the waste gas receiving portion  1101 . The air inlet  112  and the exhaust vent  115  can be connected with the receiving portion  110 . 
     The two support members  20  can be parallel to each other and mounted on two opposite inner surfaces  111  of the housing  10 . Each support member  20  can include a guiding rail  21 , and the two guiding rails  21  can face each other. 
     The filter  50  can filter the waste gas and oil fog in the waste gas can adsorb on the filter  50 . The filter  50  can be a substantially rectangular plate and positioned on the two support members  20 . Two ends of the filter  50  can be slide on the guiding rail  21 , and the filter  50  can slide into or slide out of the housing  100 . 
     The spraying module  70  can be positioned on top of the filter  50  and can include a plurality of sprayers  71  used to spray the filter  50  and form water films on the filter  50 . The oil fog can condense or solidify with the water films, and then drip to the storage container  117  with the water films. 
     The central portion of storage container  117  can define a filler  1173  communicated to the water tank  91  and a feed water inlet  1175  communicated to the water pump  93 . The water tank  91  can be connected to an external water source to supply water to the storage container  117 , and the water pump  93  can pump the water to the spraying module  70 . The circulation module  90  can further include a water filter (not shown) connected to the storage container  117  and the water pump  93 , configured to filter the water, thus the water in the storage container  117  can be filtered and transported by the water pump  93 , and then supplied to the spraying module  70 . Therefore, the water in the storage container  117  can be recycled. When the residue in the water meets or exceeds a pre-determined value, the water can exit through the drain pipe  1171 , and the water tank  91  can supply water to the storage container  117  from the external water source again. The filter can prevent the residue in the water from blocking up the sprayers  71 . 
       FIG. 3  illustrates that the cleansing device  100  can further include a seal cover  15  detachably mounted on the housing  10 . The housing  10  can further define an assembly hole  113 , the two support member  20  are positioned on two sides of the assembly hole  113 . The filter  50  can be assembled in the cleansing device  100  through the assembly hole  113  and slide on the guiding rails  21  of the support members  20 . 
       FIG. 4  illustrates that the seal cover  15  can seal the assembly hole  113  to prevent the waste gas flowing out of the assembly hole  113 . 
     In operation, the fan  30  can rotate to lead the external waste gas into the receiving portion  110 , and the water tank  91  can supply water to the storage container  117 . The water in the storage container  117  can be filtered and then transported to the spraying module  70  by the water pump  93 . The sprayers  71  can spray water to the filter  50  and the water films can be formed on the filter  50 . The oil fog can condense or solidify and drip to the storage container  117  with the water films. The water in the storage container  117  can be filtered and transported to the spraying module  70 , until the residue in the water meets or exceeds some predetermined threshold, and the water can exit through the drain pipe  1171 . 
     When replacing the filter  50 , the seal cover  15  can be detached from the housing  100 , and the filter  50  can be pulled out along the guiding rails  21  of the support members  20 . Then, the filter  50  can be cleaned and returned into the receiving portion  110  along the guiding rails  21  or the filter  50  can be replaced in a similar manner with a new, clean filter. 
     The cleansing device  100  can include two support members  20  positioned parallel in the receiving portion  110  and on two sides of the assembly hole  113 , the filter  50  can be mounted on the support members  20  through the assembly hole  113 . The filter  50  can slide into and out of the receiving portion  110  along the guiding rails  21  of the support members  20 , so that the filter  50  can be detached more easily for convenient replacement and cleaning 
     In other embodiments, the fan  30  can be omitted, and the waste gas can flow into the receiving portion through the air inlet  112 . The seal cover  15  can also be omitted. 
     In other embodiments, the circulation module  90  can be omitted, and the spraying module  70  can be directly connected to the external water source. 
     In other embodiments, the filter in the storage container can be omitted, and the water pump  93  can directly supply the water in the storage container  117  to the sprayer module  70 . 
     In other embodiments, the assembly hole  113  can be omitted, and one side wall of the housing  10  can be detached and the filter  50  can then be assembled on the support members  20 .
