Description

Technical Field

[0001] The utility model relates to the technical field of water purifier installation structures, and in particular to a blocking component, a buckle assembly structure and a side-insertion filter element installation system. Background Art

[0002] In the prior art, the filter element of a water purifier generally adopts a plug-in filter element, and a plug-in filter element means that the filter element bottle is directly plugged into the waterway plate vertically. Although this connection method allows the water to flow directly between the filter element and the waterway plate without turning, and the water flow turbulence is less, this connection method has some defects: (1) The connection between the filter element bottle and the waterway plate is at a right angle. In the actual structure, since the filter element is mostly placed vertically, the waterway plate is also placed vertically, making the shape of the entire water purifier a rectangular parallelepiped, which is not conducive to the diversified design of the water purifier shell; (2) The filter element has a service life of several months. After the filter element reaches its service life, the filter element needs to be replaced. The bottom of the filter element bottle using this connection method generally contacts the water purifier shell, making it difficult to replace the filter element. How to provide a new filter element plug-in method that can ensure its stable installation and simple assembly and disassembly is a technical problem that urgently needs to be solved in the prior art.

[0026] The installation and structural application principles are as follows:

[0027] The buckle assembly structure 1 is flipped open around its rotation axis 113 to an open state, allowing the filter bottle mounting position to be opened. Then, a filter bottle structure 2 is placed in the filter bottle mounting position, and the lower bottle body 201 of the filter bottle structure 2 is placed and supported. A plurality of water receiving ends communicating with the internal filtering material and the filtering flow path of the bottle body 201 are provided on the mounting end 202 at the upper part of the filter bottle structure 2. The user applies force to the filter bottle structure 2 from the side to insert its water receiving ends into the corresponding water circuit board assembly 3, and then by flipping and lowering the buckle assembly structure 1, the buckle assembly structure 1 is buckled and fitted with the mounting end 202 of the filter bottle structure 2, so that the filter bottle structure 2 can be installed on the rack and the stable water connection with the water circuit board assembly 3 can be completed.

[0028] Embodiment 1:

[0029] Based on the above structural application, this embodiment provides a specific setting scheme for the buckle assembly structure 1 and the filter bottle structure 2 for application description. While the buckle assembly structure 1 satisfies the installation of the filter bottle structure 2 for the above side insertion application, it realizes the locking of the filter element installation, ensures that the installation of the filter element has a stable installation effect, and has the characteristics of simple, efficient installation and disassembly.

[0030] Specifically, the filter bottle structure 2 includes a bottle body 201 with an upper opening, and an installation end 202 cover is installed and connected on the upper side of the bottle body 201 as the installation end 202. A water receiving end extending horizontally is provided on one side of the installation end 202 cover; a buckling position 22 is provided on the other side of the installation end 202 cover.

[0031] The buckle assembly structure 1 includes a buckle body 11 in a U shape. The ends of the vertical sections 112 on both sides of the buckle body 11 extend outward to form rotation axes 113 for rotational connection to the filter element mounting position. A mounting space adapted to the outer peripheral shape of the installation end 202 is formed inside the U shape of the buckle body 11.

[0032] A guiding connector 110 is provided on the upper side of the transverse section 111 of the buckle body 11 and is opened in the front-back direction. In this embodiment, the inner side of the buckle body 11 is used as the rear side, and the outer side of the transverse section 111 of the buckle body 11 is used as the front side position for reference.

[0033] A latch 12 is provided in the guide connection of the guide connector 110, and a reset spring 122 is connected between the latch 12 and the latch body 11. The latch 12 is provided with a latch position 120 toward the inner side of the latch body 11, and a blocking component 13 can be mounted on the lower side of the transverse section 111, and the blocking component 13 forms a blocking end face 130 toward the inner side of the latch body 11; the reset spring 122 applies a reset force to the latch 12 toward the rear side and against the transverse section 111 and / or the blocking component 13.

[0034] A snap-fitting portion 22 is provided on one side of the mounting end 202 of the filter bottle structure 2, which snaps into engagement with the snap-fitting portion 120. When the hand-clasp assembly structure 1 is flipped and moved downward to engage the mounting end 202, the snap-fitting portion 22 corresponds to the position of the snap member 12, and the return spring 122 applies a return force to the snap member 12 toward the snap-fitting portion 22, thereby snapping the filter bottle structure 2 onto the hand-clasp assembly structure 1.

[0035] Example 2:

[0036] In this embodiment, the structural setting method of the buckle assembly structure 1 is further described.

[0037] Preferably, a lifting handle 115 is provided on the lower outer side of the horizontal section 111 of the buckle body 11 and extends forward; a positioning groove 116 with an opening facing downward is provided on the inner side of the vertical section 112 of the buckle body 11; through the setting of the lifting handle 115, the user can more easily bend and flip the buckle assembly structure 1, so that the buckle assembly structure 1 can be flipped and rotated around the rotation axis 113.

[0038] In the filter bottle structure 2 , positioning blocks are provided on both sides of the mounting end 202 . When the buckle assembly structure 1 is flipped and moved downward to engage with the mounting end 202 , the positioning blocks are connected to the positioning grooves 116 .

[0039] In the buckle body 11, the outer contour of the connection position between the vertical section 112 and the horizontal section 111 on both sides is set in an arc shape; the outer peripheral edge of the upper front end of the buckle 12 corresponds to the outer contour of the horizontal section 111 and is set in an arc shape; a pull handle 123 is set on the upper side of the buckle 12, and the pull handle 123 is set at a pull position in the shape of an arc toward the rear side. The overall arc-shaped matching setting can ensure the user's gripping experience of the buckle assembly structure 1, and avoid the user's poor experience caused by the angular structural edges. At the same time, the setting of the pulling handle can facilitate the user to move the buckle 12 as a whole by pulling the handle, and control the buckle position 120 to be connected / released at the buckle position 22.

[0040] In the buckle body 11, pushing blocks 114 are provided on the lower side of the ends of the vertical sections 112 on both sides. Correspondingly, interference blocks 21 are provided on both sides of the mounting end 202 of the filter bottle structure 2 to match the positions of the pushing blocks 114 on both sides. When the buckle assembly structure 1 is flipped down and engaged with the mounting end 202, the pushing block 114 is in contact with and abuts against the interference block 21, and the interference block 21 is located in front of the pushing block 114. When the buckle assembly structure 1 is flipped up, the pushing block 114 pushes the interference block 21 along with the flipping action, and the pushing action of the pushing block 114 pushes the filter bottle structure 2 away from the waterway plate assembly 3, so that the filter bottle structure 2 can be disassembled out of the filter bottle mounting position.

[0041] For the said fastener 12, its structure includes a pull block 121 which is arranged in a straight plate shape as a whole; the said guide connector 110 has guide plates arranged on both sides along the front-to-back direction, and an L-shaped connecting groove structure 1210 is provided on the lower side of the said pull block 121 so that the two sides of the lower side form guide grooves extending along the front-to-back direction, so that the said guide plates are connected to the said guide grooves, so that the said fastener 12 is guided and connected to the guide connector 110.

[0042] A clamping section 1211 is provided at the lower middle part of the pull block 121, and a clamping block 1212 is provided at the rear side of the clamping section 1211, and the clamping position 120 is formed between the clamping section 1211 and the clamping block 1212; a spring installation position is provided at the front end inside the transverse section, and the return spring 122 is connected between the spring installation position and the clamping stage 1211.

[0043] The retaining member 13 includes two vertically arranged support vertical sections 131. The lower ends of the two support vertical sections 131 are connected by a bracket cross section 132. An extension section 133 extends rearward from the upper ends of the two support vertical sections 131. The two extension sections 133 are connected by a support cross section 134. The retaining end surface 130 includes a middle positioning end surface 1302 located behind the support vertical section 131, a lower positioning end surface 1303 located rearward of the bracket cross section 132, and an upper positioning end surface 1301 located rearward of the support cross section 134. The retaining member 13 has a central space 135 connecting the front and rear ends.

[0044] There is a horizontal spacing between the upper positioning end surface 1301 and the middle positioning end surface 1302, and there is a horizontal spacing between the middle positioning end surface 1302 and the lower positioning end surface 1303. The upper positioning end surface 1301, the middle positioning end surface 1302, and the lower positioning end surface 1303 are sequentially spaced apart in the horizontal direction from back to front, meeting the requirements for positioning the mounting end 202 structure with increasing radial dimensions from top to bottom.

[0045] Preferably, the lower positioning end face 1303 is an arc-shaped end face, the middle positioning end face 1302 is a vertical end face extending vertically, and an inclined positioning surface 136 is arranged between the middle positioning end face 1302 and the lower positioning end face 1303, and the inclined positioning surface 136 is arranged to be inclined from top to bottom toward the front side; this arrangement is provided through the arc-shaped end face and the inclined inclined positioning surface 136, which can ensure that the blocking component 13 is stably assembled when the buckle assembly structure 1 is flipped over to adapt to the filter bottle structure 2 and can avoid the flipping action causing scratches on the filter bottle structure 2 due to the blocking component 13 structure.

[0046] The outer peripheral edge of the front side of the bracket transverse section 132 is configured to be arc-shaped, so that the front side of the bracket transverse section 132 abuts against the inner front end of the transverse section 111 of the buckle body 11, forming a more effective and stable assembly.

[0047] A plurality of supporting blocks 1341 extending in the front-to-back direction are provided on the upper side of the supporting cross section 134 . The supporting blocks 1341 are used to support the lower side of the rear end of the pulling block 121 to ensure stable assembly between the latch 12 and the blocking member 13 .

[0048] As a preferred installation and fixing method, in the buckle body 11, a mounting tube 1110 is provided at the upper end of the inner side of the transverse section 111 thereof, facing downward. In the blocking member 13, vertical section through holes 1311 are provided through the two supporting vertical sections 131. The mounting tube 1110 is inserted and assembled into the vertical section through holes 1311, thereby completing the application of positioning and attaching the blocking member 13 to the buckle body 11. The inner side of the mounting tube 1110 is provided with an internal thread. In actual application, a screw can be inserted from the lower side of the vertical section through holes 1311 to lock into the internal thread, thereby completing the fixing and installation of the blocking member 13 to the buckle body 11.

[0049] The rear end of the slot structure 1210 below the pull block 121 serves as a stopper 1213, and the rear side of the slot structure 1210 corresponds to the front side of the support cross section 134. When the hand assembly structure 1 flips down and engages the mounting end 202, the return spring 122 applies a return force toward the engaging position 22 to the latch 12, causing the rear side of the slot structure 1210 to abut against the front side of the support cross section 134, allowing the stopper 13 to limit and block the latch 12. The space 135 facilitates the engagement of the latch block 1212 in the latch 12 with the engaging position 22 on the filter bottle structure 2.

[0050] The above is only a preferred embodiment of the present invention. Those skilled in the art can modify the embodiment without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as within the scope of protection of the present invention.
