Description

The package assembly of filter

The utility model relates to a kind of package assembly of improved filter.

Three-dimensional exploded view referring to the filter of present use shown in Figure 1, present normally used filter A mainly is made up of a loam cake A1, capacity body A2 and filter core B, wherein, offer entery and delivery port A11, A12 on the loam cake A1 respectively, offer thread segment (figure does not show) on its madial wall, capacity body A2 is the staving of hollow, has an accommodation space A21 in it, and in accommodation space A21 lower end when accommodating body A2 ejection formation, the one-body molded inserting-connection block A22 that convexes with; When assembling, filter core B is placed in the accommodation space A21 of accommodating body A2, at this moment, the inserting-connection block A22 that is positioned at the accommodation space A21 lower end of accommodating body A2 then is plugged on the lower port place of filter core B intermediate throughholes B1, make that the water that filters can be in the through hole B1 lower port admission passage B1 of filter core B, again with loam cake A1 and accommodating body A2 screw lock mutually, promptly finish its assembling, at this moment, the upper port of filter core B center-aisle B1 then engages with the water outlet A 12 of loam cake A1, make water to be filtered from the water inlet A 11 of loam cake A1 in accommodating body A2 accommodation space A21, and after the nationality filter core B filtration, go among the B1 of passway by the outside seepage flow of filter core B, flow to the water outlet A 12 of loam cake A1 again by the upper port of passway B1, and discharge by water outlet A 12.And as will install a plurality of filter A continuously additional the time, then referring to the filter assembling schematic diagram of present use shown in Figure 2.As seen from the figure, when desiring to install many filter A continuously additional, the essential utilization connects water pipe C with filter A in addition in succession, at this moment, connect the water outlet A 12 that one of water pipe C is connected to front filter A loam cake A1, the other end of this water pipe C then is connected to water inlet A 11 places of after-filter A loam cake A1, but make the connection of the water nationality connection water pipe C in the filter A, flow into the water inlet A 11 of after-filter A by the water outlet A 12 of front filter A, flow into accommodating body A2 again and carry out secondary, three times ... Deng filtration, this filter commonly used assembling mode and frame mode have been used for many years, though can be said to be convenient substantially, but still have following defective:

One, now the filter cover that uses is shaped as circle, its area is slightly larger than accommodating body, as will carry out the assembling of a plurality of filters the time, must be connected by nationality connection water pipe, construction is quite inconvenient, and the bore of adding the connection water pipe is all less, therefore water yield is few, thus on assembling, cost and water yield neither economy and making things convenient for.

Its two, now the filter cover that uses be directly with accommodating body screw lock mutually because it can't make loam cake and accommodating body work sealed closely, seep water from screw lock easily.

Its three, accommodating body is that one-body molded mode is finished, its cost cost is quite high, thereby the price of whole device is also increased.

Provide a kind of package assembly of improved filter in the purpose of utility model, so that its overall package process is convenient more, and water yield can not diminish, and omits the connection that connects water pipe.

The utility model be achieved in that its mainly by one into and out of water cover, the piece that spins, an accommodating body and the piece that blocks water are formed, it is characterized in that: wherein water-in and water-out cover to hold and are large tracts of land and rectangular engaging groove, and screwing section is established in the lower end, and the piece that wherein spins is the block of a hollow, be provided with in it and be nested with the hole, its inner top side offers screwing section, at the lower end of screwing section, is provided with the joining section that the aperture is smaller, take the form of inclined plane; Wherein accommodating body is the hollow staving that adopts the moulding of pressing mode, is accommodation space in it, and its upper port place offers the joining section that takes the form of inclined plane; And the piece that wherein blocks water is located in the middle of being positioned at, and convexes with insertion section; Nationality is designed by said structure, during assembling, the insertion section of the piece that blocks water is plugged on the lower end of filter core through hole and is placed in the accommodation space of accommodating body, again accommodating body is nested with being nested with in the hole at the piece that spins, and the inclined-plane joining section that makes the accommodating body upper port is with after inclined-plane joining section in the piece that spins engages, the screwing section that utilizes the piece inboard that spins again with advance, the lower end screwing section phase screw lock of outflow cover for water, and utilize, the lower end screwing section lower end of outflow cover for water is pressed on inclined-plane, the accommodating body upper end joining section mutually, screwing into, in the time of outflow cover for water, make accommodating body upper end joining section tightr with the engaging of the interior joining section of piece that spin.

Wherein water-in and water-out cover on the two sides of engaging groove of end, offer entery and delivery port and locking holes respectively.

Visual needs of its middle filtrator and increase the quantity of filter, when engaging, the delivery port of front filter engages with the water inlet of after-filter, and is equipped with a sealing ring therebetween, then is equipped with the bolt of locking in the locking holes that the water-in and water-out of each filter cover.

The contact-making surface of above-mentioned filter and filter and be positioned on the water-in and water-out actinal surface of water cover and all adopt " face " way of contact.

The utility model is a kind of have good compactness and ease of assembly, can reduce the filter of its cost significantly, mainly by being formed into and out of water cover, the piece that spins, accommodating body and the piece that blocks water, during assembling, the piece that blocks water is placed in the accommodating body after being plugged on the filter core bottom, accommodating body is inserted in the piece that spins, the joining section that the makes accommodating body upper end just joining section in the piece that spins engages again, and will pass in and out water cover again and the piece that spins is screwed and promptly finishes assembling.And when desiring to carry out the assembling of many set filters, then be nested with sealing ring respectively at the entery and delivery port place of filter, and and the delivery port of front filter is put mutually with the water inlet of after-filter close, utilize bolt that the mutual screw lock of filter is fastening and finish assembling again.This structural design makes and improves into and out of the compactness between water cover and accommodating body and the filter, and need not external water pipe that so assembling is quite convenient, adding accommodating body is combination forming, is not one-body molded, and its manufacturing cost can significantly be reduced.
