Description

Technical Field

[0001] The utility model belongs to the field of water purifier equipment, and in particular relates to a quick-change filter bottle structure. Background Art

[0002] The filter bottle in the water purifier equipment usually needs to be fixed on the main body or waterway plate. If the filter bottle is not fixed inside the machine, the filter bottle will fall out and water will flow out during normal use, causing the machine to stop working; however, the existing technology often uses a more complex structure to fix the filter bottle or the filter bottle can only be removed by a greater force.

[0003] Most of the filter bottles on the market are installed in a rotating manner, with many parts and components, and require a specially designed rotating base, which also requires a large number of screws for locking. The filter bottle also needs to be rotated in the opposite direction when taken out, but at this time it is necessary to overcome the friction between the two clamping turntables and the rubber ring, which causes a large rotational friction between the filter bottle and the base, requiring a huge torque to rotate the filter bottle in the opposite direction out of the base.

[0004] A filter bottle and filter bottle cover connection and rotation structure is currently disclosed (patent application number: CN202023068358.8), which includes a plurality of lock buckles arranged on the outer peripheral surface of the bottom of the filter bottle body handle, and the filter bottle body handle arranged above the lock buckle forms a limit for the lock buckle along the axial direction of the filter bottle body, the filter bottle body handle is located at the top of the filter bottle body, and its cross-section is circular, and the cross-section of the filter bottle body located below the filter bottle body handle is circular; the connection and rotation structure formed between the filter bottle body and the filter bottle cover fixedly connected to the outside of the lock buckle is formed by a plurality of lock buckles arranged on the outer peripheral surface of the bottom of the filter bottle body handle.

[0005] The structural design of the disclosed solution makes the rotational connection between the filter bottle cap and the filter bottle body more stable and easy to disassemble, but it does not disclose the installation method of the filter bottle. If the connection method between the filter bottle body and the main body or waterway plate adopts this kind of rotational connection method, the above-mentioned technical problems will still exist. Utility Model Content

[0009] When the filter bottle is replaced, the clamp is lifted, and the elastic clamp is contracted and separated from the clamping groove under the action of the rotation of the cam structure.

[0010] Preferably, the elastic clamp includes a pressing plate and a spring, a second mounting seat is provided on the top of the filter bottle, the pressing plate is provided with a first corner and a protrusion, both ends of the spring are respectively connected to the second mounting seat and the protrusion, and the first corner is engaged with the slot.

[0011] Preferably, there are two elastic clamps, which are symmetrically arranged on the top of the filter bottle.

[0012] Preferably, the elastic clamp is a spring sheet, which is composed of an integrated pressing head and elastic ribs. The pressing head is provided with a second corner, and the second corner is engaged with the clamping slot.

[0013] Preferably, the main body is provided with a guiding slope, which cooperates with the elastic clamp to shrink the elastic clamp toward the center of the circle, and the guiding slope corresponds to the clamping slot and is located above the clamping slot.

[0014] Preferably, the main body is provided with a limiting groove, the outer wall of the filter bottle is provided with a limiting piece, and the filter bottle is radially limited on the limiting groove by the limiting piece.

DETAILED DESCRIPTION

[0027] Example 1

[0028] like Figure 1-5 As shown, a quick-change filter bottle structure includes a main body 3, a filter bottle 6 and an end cover 1, the filter bottle 6 is installed inside the main body 3, the end cover 1 covers the top of the filter bottle 6, and also includes a clamp 2 and an elastic clamp 4, the elastic clamp 4 is located between the end cover 1 and the filter bottle 6, the top of the elastic clamp 4 is against the bottom of the end cover 1, a first mounting portion 61 is provided on the top of the filter bottle 6, the elastic clamp 4 is installed on the first mounting portion 61, the clamp 2 is fixed with a cam structure 21, the cam structure 21 is installed on the first mounting portion 61 and is used to compress the elastic clamp 4, the main body 3 is provided with a clamping groove 32, when the filter bottle 6 is installed to the main body 3, the elastic clamp 4 is clamped with the clamping groove 32;

[0029] When the filter bottle 6 is replaced, the clamp 2 is lifted, and the elastic clamp 4 is contracted and separated from the clamping groove 32 under the action of the rotation of the cam structure 21 .

[0030] When the cam structure 21 starts to rotate from a horizontal state, its structure will support the end of the elastic clamp 4, so that during the rotation process, the elastic clamp 4 will continuously shrink toward the center of the circle, so that the elastic clamp 4 and the card slot 32 are no longer engaged, achieving an unlocked state, and the filter bottle 6 can be taken out from the main body 3.

[0031] The elastic clamp 4 includes a pressing plate 4A and a spring 5. A second mounting seat 63 is provided on the top of the filter bottle 6. The pressing plate 4A is provided with a first corner 41 and a protrusion 42. Both ends of the spring 5 are respectively connected to the second mounting seat 63 and the protrusion 42. The first corner 41 is engaged with the slot 32.

[0032] There are two pressing pieces 4A, and there are four springs 5, first angles 41, protrusions 42, slots 32, and second mounting seats 63, thereby forming a bilaterally symmetrical elastic structure. The second mounting seat 63 also has a structure similar to the protrusion 42, which is used to limit the spring 5 and has the same function as the protrusion 42.

[0033] There are two elastic clamps 4 , which are symmetrically arranged on the top of the filter bottle 6 .

[0034] The main body 3 is provided with a guiding inclined surface 31 , which cooperates with the elastic clamp 4 to shrink the elastic clamp 4 toward the center of the circle. The guiding inclined surface 31 corresponds to the clamping groove 32 and is located above the clamping groove 32 .

[0035] As the filter bottle 6 is installed on the main body 3, the elastic clamp 4 first contacts the guide slope 31, thereby continuously shrinking until it is installed to the specified position. Under the action of the spring 5, the elastic clamp 4 rebounds and engages with the slot 32 to complete the fixation of the filter bottle 6.

[0036] The main body 3 is provided with a limiting groove 33 , and the outer wall of the filter bottle 6 is provided with a limiting member 64 , and the filter bottle 6 is radially limited on the limiting groove 33 by the limiting member 64 .

[0037] The cooperation between the limiting member 64 and the limiting groove 33 enables the filter bottle 6 to be installed with the main body 3 at a specified position, playing a role of limiting and guiding, and the filter bottle 6 cannot rotate.

[0038] A buckle hole 62 is provided on the top of the filter bottle 6 , and a buckle 13 is provided on the inner wall of the end cover 1 , and the buckle 13 is engaged with the buckle hole 62 .

[0039] There are four buckles 13 and buckle holes 62, which are evenly arranged on corresponding structures.

[0040] A first opening 11 and a second opening 12 are provided on the circumferential side wall of the end cover 1 . The cam structure 21 on the clamp 2 extends into the end cover 1 through the first opening 11 , and the engaging portion of the elastic clamp 4 extends out of the end cover 1 through the second opening 12 .

[0041] The first opening 11 and the second opening 12 have similar functions. The first opening 11 is for the structure of the clamp 2, so that the cam structure 21 and the ring body of the clamp 2 can be connected and rotate synchronously; the second opening 12 is to allow the first corner 41 or the second corner 45 (corner, i.e., the engaging part) to extend from the end cover 1 or retract into the end cover 1. Figure 5 The first opening 11 and the second opening 12 in the image are not clearly visible. Figure 2 In the structure shown in the middle end cover 1 , the opening on the left is the second opening 12 , and the opening on the right is the first opening 11 .

[0042] like Figure 1 As shown, when the filter bottle 6 is installed on the main body 3, a gap is provided between the end cover 1 and the main body 3, and the ring body of the clamp 2 is placed in the gap.

[0043] The working principle of the filter bottle structure is as follows: when installing the filter bottle 6, the pressing piece 4A contacts the guiding inclined surface 31 of the main body 3, and the pressing piece 4A will shrink horizontally toward the center of the circle due to the compression of the spring 5. When the filter bottle 6 is installed in place, the pressing piece 4A moves horizontally outward due to the rebound of the spring 5 and the four first corners 41 are inserted into the corresponding grooves 32 of the main body 3, fixing and limiting the filter bottle 6 from slipping outward; when taking out the filter bottle 6, the clamp 2 is connected to the pressing piece 4A through the cam structure 21. When the clamp 2 is lifted to an angle of 45°, the cam compresses the pressing piece 4A horizontally toward the center of the circle, and the four first corners 41 of the pressing piece 4A are disengaged from the corresponding grooves 32 of the main body 3. When the clamp 2 is lifted to an angle of 50°, the ejection ribs of the clamp 2 push the limiting surface of the main body 3 to eject the filter bottle 6 upward, thereby taking the filter bottle 6 out of the main body 3.

[0044] Example 2

[0045] The difference between this embodiment and embodiment 1 is that: Figure 4 and Figure 5 As shown, the elastic clamp 4 is a spring sheet 4B, which is composed of an integrated pressing head 43 and an elastic rib 44 . The pressing head 43 is provided with a second corner 45 , and the second corner 45 is engaged with the clamping slot 32 .

[0046] In this embodiment, the second mounting seat 63 for connecting with the spring 5 is no longer provided on the top of the filter bottle 6, and the rest of the structure is the same.

[0047] Compared with the first embodiment, the present embodiment is a deformation of the elastic clamp 4, and the function and working principle are the same.

[0048] Example 3

[0049] The difference between this embodiment and embodiment 1 is that the number of buckles 13 and buckle holes 62 are both three, the three buckles 13 are evenly distributed on the end cover 1 at intervals of 120 degrees, and the three buckle holes 62 are evenly distributed on the filter bottle 6 at intervals of 120 degrees.

[0050] The above description is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by any technician in the field of the present invention are included in the patent scope of the present invention.
