Description
- 1. Field of the Invention
- The invention relates to a pump, more particularly to a pump that is capable of screening out coarse contaminants from fluid.
- 2. Description of the Related Art
- Referring to
FIG. 1 , an above-ground swimming pool 1′ is provided with apump 2′ for circulating water from the above-ground swimming pool 1′ to a processing unit, such as a heater, and for pumping the processed water back to the above-ground swimming pool 1′. Theconventional pump 2′ is usually provided with a filter unit (not shown) for filtering out fine contaminants from water. However, in addition to the fine contaminants, the water also contains coarse contaminants, such as leaves, little branches, pebbles, and the like, which can block the filter unit. Therefore, anadditional screen member 3′ is required to screen out the coarse contaminants from water before the latter enters into thepump 2′ . Therefore, an additional cost is required for thescreen member 2′ . - Therefore, the object of this invention is to provide a pump that can overcome the aforesaid drawback associated with the prior art.
- The pump capable of screening out coarse contaminants from fluid according to this invention includes a pump housing with a fluid-entering portion and a fluid-exiting portion, a screen unit mounted on the fluid-entering portion and having holes for screening out the coarse contaminants from the fluid, and a filter unit mounted on the fluid-exiting portion and having holes for filtering out fine contaminants from the fluid. The holes of the screen unit are larger than the holes of the filter unit.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiment with reference to the accompanying drawings, of which:
-
FIG. 1 is a schematic view a conventional pump used for an above-ground swimming pool; -
FIG. 2 is an exploded perspective view of the preferred embodiment of the pump according to this invention; -
FIG. 3 is an assembled perspective view of the preferred embodiment; and -
FIG. 4 is a schematic partly sectional view to illustrate the preferred embodiment in a state of use. - Referring to
FIGS. 2 and 3 , the preferred embodiment of a pump capable of screening out coarse contaminants from fluid according to this invention is shown to include a pump housing 1, ascreen unit 2, and afilter unit 3. - The pump housing 1 includes a fluid-entering
portion 11 and a fluid-exitingportion 12. The fluid-enteringportion 11 includes a firsttubular wall 13 which defines areceiving space 10, and which has afirst end 132 connected to the pump housing 1 and asecond end 133 extending away from the pump housing 1, and afirst inlet port 131 projecting from the firsttubular wall 13 between the first andsecond ends receiving space 10 of the pump housing 1. The fluid-enteringportion 11 further includes afirst opening 130 formed at thesecond end 133 of the firsttubular wall 13. The firsttubular wall 13 is formed with an outer threadedportion 14 proximate to thesecond end 133 thereof. The fluid-enteringportion 11 further includes acover 15 having an inner threadedportion 151 for threadedly engaging the outer threadedportion 14 of the firsttubular wall 13 such that thecover 15 can close removably thefirst opening 130. - The fluid-exiting
portion 12 includes a threadedannular flange 16 extending from the pump housing 1, and acap 17 having an inner threaded portion (not shown) for threadedly engaging the threadedannular flange 16. Thecap 17 further has anoutlet port 171 at the top thereof for connecting with a tubular member (not shown) to permit transport of the fluid from the pump housing 1. - The
screen unit 2 is mounted on the fluid-enteringportion 11 and hasholes 22 for screening out the coarse contaminants from the fluid. The size of each of theholes 22 of thescreen unit 2 is smaller than that of thefirst inlet port 131. Thescreen unit 2 includes a secondtubular wall 24 surrounded by the firsttubular wall 13, asecond inlet port 21 projecting toward thefirst inlet port 131 from the secondtubular wall 24, and anend wall 25 connected to the secondtubular wall 24 proximate to thefirst end 132 of the firsttubular wall 13. Theholes 22 of thescreen unit 2 are formed in the secondtubular wall 24 and theend wall 25. Thescreen unit 2 further has a second opening 26 opposite to theend wall 25. The secondtubular wall 24 has arim 27, which projects outward and around the secondtubular wall 24 proximate to thesecond opening 26. Therim 27 is seated on thesecond end 133 of the firsttubular wall 13. Thescreen 2 further has ahandle 23 pivotally mounted on the secondtubular wall 24 proximate to thesecond opening 26. - The
filter unit 3 is mounted on the fluid-exitingportion 12, and has holes for filtering out fine contaminants from the fluid. Theholes 22 of thescreen unit 2 are larger than the holes of thefilter unit 3. Thefilter unit 3 is covered by thecap 17, and further has acentral passage 32 fluidly communicated with theoutlet port 171 of thecap 17. - Referring to
FIG. 4 , in use, as indicated by the arrows inFIG. 4 , the fluid first enters into thescreen unit 2 through thefirst inlet port 131 and thesecond inlet port 21. The coarse contaminants contained in the fluid can be filtered out from the fluid by thescreen unit 2 when the fluid passes through thescreen unit 2 via theholes 22 of thescreen unit 2. The fluid passing through thescreen unit 2 is then passed through thefilter unit 3 so as to filter out the fine contaminants from the fluid, and is subsequently transported out of the pump through thecentral passage 32 of thefilter unit 3 and theoutlet port 171 of the cap 7. In view of the aforesaid, the coarse contaminants contained in the fluid can be first filtered out from the latter by thescreen unit 2 so as to prevent the holes of thefilter unit 3 from being blocked by the coarse contaminants. Therefore, the drawback of the prior art can be avoided. Furthermore, since thecover 15 is removable, cleaning of thescreen unit 2 can be conveniently conducted whenever necessary. - Preferably, the
cover 15 and thecap 17 are made of transparent plastics so that user is able to determine whether thescreen unit 2 and thefilter unit 3 have to be cleaned or replaced by simply viewing through thecover 15 and thecap 17. While the present invention has been described in connection with what is considered the most practical and preferred embodiment, it is understood that this invention is not limited to the disclosed embodiment but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
