Further, a plurality of protruding blocks are arranged on the filter element and at the connecting end of the filter element and the locking device, and a fixed cover groove for the protruding blocks to pass through is arranged on the fixed cover of the sliding plate. And two side surfaces of the central through hole of the button sliding block are provided with sliding block grooves which are in staggered connection with the convex blocks, and the connection and separation of the filter element are realized through the matching of the sliding block grooves and the convex blocks.
Still further, a valve core spring is arranged between the filter core check valve and the shell. The button slider slides back and forth through a spring arranged at the other end of the button slider. The locking device is fixedly connected to the shell through the fixing seat.
Further, the right end of the filter element is provided with a button module. The connecting rod is fixed on the filter element through a connecting rod supporting frame. A plurality of connecting rod springs are arranged on the connecting rod along the axial direction of the connecting rod. The contact end of the connecting rod and the button sliding block is provided with a concave slope, and locking and unlocking are carried out through the contact of the slope and the button sliding block.
The beneficial effects are that: compared with the prior art, the invention has the remarkable advantages that: the device is through the cooperation between button module, connecting rod and locking device to can be under the condition that the water purifier is small, change the space limited, change the filter core conveniently, not only improve the operating efficiency, and greatly reduced the cost.

Detailed Description
The technical scheme of the invention is further described in detail below with reference to the accompanying drawings.
The portable filter element replacing device comprises a shell 1 and a plurality of filter units which are arranged in parallel and are arranged in the shell 1. The filter unit comprises a filter element 2 which is perpendicular to the shell 1, a locking device 3 which is arranged on one side of the filter element 2, and a filter element check valve 4 which is arranged on one side of the locking device 3 and is fixed on the shell 1, wherein a valve element spring 11 is further arranged between the filter element check valve 4 and the shell 1, namely, the filter unit sequentially comprises the filter element 2, the locking device 3 and the filter element check valve 4 which is fixed on the shell 1 from left to right, as shown in fig. 1 and 2. The locking device 3 is fixedly connected to the shell 1 through a fixing seat 15, the filter element 2 is fixedly provided with a connecting rod 5, the connecting rod 5 is arranged on the side edges of the filter element 2 and the locking device 3 through a connecting rod supporting frame 13, and a plurality of connecting rod springs 14 are axially arranged on the connecting rod 5 along the connecting rod 5 so that the connecting rod can reciprocate, as shown in fig. 3.
Wherein, locking device 3 includes the fixed lid 6 of slide and button slider 7 that all have central through-hole, and filter core 2, with the link department of locking device 3 be equipped with a plurality of lugs 8, the fixed lid recess 9 that supplies these a plurality of lugs 8 to pass are equipped with to the both sides of central through-hole on the fixed lid 6 of slide, button slider 7 is also central through-hole, the same central through-hole both sides face be equipped with the slider recess 10 of the looks complex of lug 8, and slider recess 10 and the face that the lug 8 both contacted are the inclined plane that cooperatees. The tail end of the button slider 7 is provided with a spring, and the spring is fixed between the slider fixing cover 6 and the filter element check valve 4 in a mode of sliding back and forth, and then the relative positions of the slider groove 10 and the lug 8 are adjusted through sliding, so that the connection and separation of the filter element 2 are realized, the top end (namely the button position) of the button slider 7 is contacted with the connecting rod 5, a concave slope 16 is arranged at the contact end of the connecting rod 5 and the button slider 7, and locking and unlocking are carried out through the contact of the slope 16 and the button slider 7, as shown in fig. 4.
