[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0029] See also Figure 1-4 The utility model provides a shell assembly structure, including a shell 1, a mounting plate 2 and an elastic member 3. The shell 1 is provided with a mounting cavity 11, and one end of the shell 1 is provided with an opening 12, which is connected to the mounting cavity 11. The mounting plate 2 is rotatably mounted on the opening 12 to close or open the mounting cavity 11, and the shell 1 and the mounting plate 2 are connected by the elastic member 3, and the elastic member 3 is in a compressed state in the closed state.

[0030] In the present invention, one side of the housing 1 is open to form an opening 12, and the interior of the housing 1 is a hollow structure to form a mounting cavity 11, and the opening 12 is connected to the mounting cavity 11, so that the internal components of the water purifier can be disassembled and assembled in the mounting cavity 11 through the opening 12. The mounting plate 2 is adapted to the opening 12 design, and the mounting plate 2 is rotatably mounted at the opening 12 of the housing 1 to realize the opening or closing of the mounting plate 2 through the reciprocating rotation of the mounting plate 2, thereby opening or closing the mounting cavity 11, and making the elastic member 3 in a natural extension state or compression state.

[0031] The principle of the housing assembly structure of the utility model is as follows:

[0032] The external force drives the mounting plate 2 to rotate to close the opening 12, at which time the mounting cavity 11 is closed and the elastic member 3 is compressed. When the mounting cavity 11 needs to be opened, the external force is removed, and the elastic force of the elastic member 3 to restore the deformation drives the mounting plate 2 to pop out of the opening 12 and rotate to open the opening 12, thereby opening the mounting cavity 11.

[0033] Therefore, the utility model provides an elastic member 3 to cooperate with the rotating structure to compress the elastic member 3 when the mounting plate 2 rotates relative to the housing 1 to close the mounting cavity 11, and utilizes the deformation force of the elastic member 3 to pop out the mounting plate 2 to open the mounting cavity 11 when the mounting plate 2 rotates in the opposite direction relative to the housing 1, thereby realizing rapid disassembly and assembly of the housing 1. In addition, when the filter element 6 of the water purifier is replaced, it is not necessary to completely disassemble the housing of the water purifier, which has the characteristics of simple assembly structure and convenient operation.

[0034] In the utility model, the external force that drives the mounting plate 2 to rotate the pen-turning opening 12 is realized by a snap-fit ​​structure, that is, the shell 1 and the mounting plate 2 are locked and connected by a snap-fit ​​structure, and the snap-fit ​​structure includes correspondingly arranged and adapted convex parts and groove parts, the convex parts are installed on the mounting plate 2, and the groove parts are installed on the shell 1.

[0035] Specifically, the convex part is arranged on the mounting plate 2 and faces the housing 1, the slot part is arranged on the housing 1 and faces the mounting plate 2, the convex part and the slot part are adapted and arranged correspondingly, and the locking and unlocking of the convex part and the slot part are realized by pressing. In the open state, the user manually rotates the mounting plate 2 to close the opening 12 and presses to realize that the convex part is clamped in the slot part and the elastic part 3 is compressed, so as to realize the locking of the housing 1 and the mounting plate 2, thereby closing the mounting cavity 11. When it is necessary to open, the user manually presses to realize that the convex part pops out of the slot part, the mounting plate 2 is unlocked from the housing 1, and the elastic force of the elastic part 3 to restore the deformation drives the mounting plate 2 to pop out from the opening 12 and rotate to open the opening 12, so as to realize the opening of the mounting cavity 11.

[0036] Therefore, the utility model realizes the reciprocating rotation of the mounting plate 2 relative to the housing 1 to unlock or lock the mounting plate 2 by the cooperation of the buckle structure and the elastic member 3, thereby realizing the simultaneous opening or closing of the mounting cavity 11 and the opening 12. The assembly structure is simple and easy to operate, and there is no need to remove the mounting plate from the housing 1, so it is convenient to disassemble and assemble the filter element 6 in the water purifier.

[0037] In the present invention, the mounting plate 2 is rotatably connected to the housing 1 via a rotating shaft 4, and the rotating shaft 4 is installed in the mounting cavity 11. Two rotating shafts 4 are provided, and both sides of the mounting plate 2 corresponding to the two side walls of the housing 1 are rotatably connected to the housing 1 via the rotating shafts 4. The rotating shaft 4 is installed in the mounting cavity 11 and is rotatably connected to the corresponding side walls of the housing 1 and the side of the mounting plate 2, so that the mounting plate 2 can reciprocate relative to the housing 1 to open or close the opening 12. The design of the rotating shaft 4 can improve the smoothness of the rotation of the mounting plate 2 relative to the housing 1, thereby improving the efficiency of disassembly and assembly.

[0038] The rotating shaft 4 is installed at the bottom of the mounting cavity 11. Moreover, the rotating shaft 4 is installed close to the opening 12. Therefore, the rotation axis of the mounting plate 2 relative to the housing 1 is located at the bottom of the mounting plate 2. On the one hand, it can be prevented that the bottom of the mounting plate 2 is installed in the mounting cavity 11 when the mounting plate 2 is rotated to open the opening 12. On the other hand, the rotation axis is located at the bottom of the mounting plate 2 to increase the opening angle of the mounting plate 2 compared to the opening 12, so as to facilitate the disassembly and assembly of the filter element 6.

[0039] Furthermore, the rotating shaft 4 is connected to the mounting plate 2 via a connecting shaft 5, the rotating shaft 4 is rotatably mounted on the housing 1, and the two ends of the connecting shaft 5 are rotatably connected to the rotating shaft 4 and the mounting plate 2. The setting of the connecting shaft 5 can increase the rotational activity space of the mounting plate 2 compared to the housing 1, and the connecting shaft 5 cooperates with the elastic member 3 to increase the ejection distance of the mounting plate 2 and the rotation angle of the mounting plate 2 compared to the housing 1, thereby increasing the disassembly and assembly port of the filter element 6, making the disassembly and assembly of the filter element 6 more convenient.

[0040] Furthermore, the connecting shaft 5 is a telescopic shaft, that is, the connecting shaft 5 is in an extended state in the open state, and in a contracted state in the closed state, so that the disassembly opening of the filter element 6 is further enlarged, making it more convenient to disassemble and assemble the filter element 6.

[0041] The connecting shaft 5 may be a retractable and extendable sleeve shaft structure, that is, a large-diameter connecting shaft and a small-diameter connecting shaft are arranged inside and outside. In the open state, the small-diameter connecting shaft extends from the large-diameter connecting shaft to extend, and in the closed state, the small-diameter connecting shaft retracts into the large-diameter connecting shaft to shorten. Alternatively, the connecting shaft 5 is an elastic telescopic shaft, which naturally extends in the open state and is compressed in the closed state. It is worth noting that when the connecting shaft 5 is an elastic telescopic shaft, its compressed elastic force and the compressed elastic force of the elastic member 3 need to be less than the locking force of the buckle structure to ensure that the mounting plate 2 is locked in the housing 1.

[0042] On the basis of the above structure, the two ends of the elastic member 3 are elastically connected to the housing 1 and the lower part of the mounting plate 2. Therefore, when the buckle structure is unlocked, the elastic member 3 can pop out the lower part of the mounting plate 2, so that when the mounting plate 2 rotates to open the opening 12, the disassembly and assembly opening of the filter element 6 is opened wider, making it more convenient to install the filter element 6.

[0043] In one embodiment, the elastic member 3 is a torsion spring, and two extensions of the torsion spring are respectively connected to the lower portion of the mounting plate 2 and the lower portion of the shell 1, so that the torsion spring is compressed in a closed state, and returns to a natural state and pops out the mounting plate 2 when the snap structure is unlocked.

[0044] In another embodiment, the elastic member 3 is a spring 74 in the locking structure 7 of the filter element 6. That is, the mounting plate 2 is provided with two side plates 21 facing the housing 1, and the two side plates 21 extend in the same direction and are spaced apart to form an installation space 22 adapted to the filter element 6. The locking structure 7 is installed in the installation cavity 11 and is located at the bottom of the installation space 22.

[0045] See also Figure 4 , a connection portion 61 is provided at the bottom of the filter element 6. The locking structure 7 can be reciprocatingly swung in the installation cavity 11 to achieve an inclined state or a horizontal state. The locking structure 7 includes a filter element seat 71, a locking plate 72 and a waterway plate 73 arranged in sequence from top to bottom. The filter element seat 71 is provided with a guide groove 711 adapted to the connection portion 61, and the waterway plate 73 is provided with a receiving groove 731 with an upward opening and a concave downward opening. In the assembled state, the connection portion 61 passes through the guide groove 711 from top to bottom and is inserted into the receiving groove 731. The locking plate 72 is sandwiched between the filter element seat 71 and the waterway plate 73 and surrounds the connection portion 61. The reciprocating swing of the locking structure 7 can drive the locking plate 72 to move back and forth laterally relative to the waterway plate 2 to lock or unlock the filter element 6.

[0046] Specifically, a rotation shaft 732 is provided at the bottom of the waterway plate 73, and the rotation shaft 732 is transversely arranged in the middle area of ​​the bottom of the waterway plate 73, and the axial direction of the rotation shaft 732 is perpendicular to the direction of the transverse movement of the locking plate 72. The waterway plate 73 rotates around the rotation shaft 732, and the setting of the rotation shaft 732 is conducive to improving the sensitivity of the swing of the waterway plate 73, and the rotation shaft 732 is arranged in the middle area of ​​the bottom of the waterway plate 73, which improves the stability of the assembly of the filter element 6 and the locking structure 7.

[0047] At least one stopper 62 is convexly disposed on the side wall of the connection part 61 extending in the lateral moving direction of the locking plate 72, the inner wall of the locking plate 72 is concave to form an unlocking channel 721 for the stopper 62 to pass through, the groove wall of the guide groove 711 is concave to form a guide channel 712 for the stopper 62 to pass through, and the number of the unlocking channels 721 and the number of the guide channels 712 are equal to the number of the stopper 62. In the assembled state, the guide channel 712 is arranged opposite to the corresponding stopper 62 in the vertical direction, and the locking plate 72 reciprocates horizontally relative to the waterway plate 73 so that the corresponding unlocking channel 721 and the stopper 62 are arranged opposite to each other in the vertical direction or staggered in the vertical direction, thereby unlocking or locking the connection part 11.

[0048] The waterway plate 73 and the locking plate 72 are elastically connected via a spring 74 , and the spring 74 extends to the connection mounting plate 2 . The spring 74 is arranged along the lateral movement direction of the locking plate 72 , and is in a compressed state in the locked state.

[0049] Therefore, the locking or unlocking principle of the filter element 6 of the present invention is as follows:

[0050] In the unassembled state, the mounting plate 2 rotates to the tilted state to open the opening 12, and the locking structure 7 swings to the tilted state following the mounting plate 2. In this state, the spring 74 is in a naturally extended state to move the locking plate 72 laterally away from the mounting plate 2, and the guide channel 712 and the unlocking channel 721 are arranged opposite to each other up and down.

[0051] When installing the filter element 6, the filter element 6 is sequentially passed through the guide groove 711 and the locking plate 72 at the same inclination angle, and the limiter 62 is sequentially passed through the corresponding guide channel 712 and the unlocking channel 721, so that the connection portion 61 is inserted into the receiving groove 731, so that the filter element 6 is installed in the installation space 22. The installation plate 2 is pushed to rotate and close the opening 12, and the filter element 6 is driven to swing from a vertical state and the locking structure 7 to a horizontal state. The buckle structure locks the installation plate 2 with the housing 1, and the locking plate 72 is forced to move laterally toward the installation plate 2 and compress the spring 74 until the unlocking channel 721 is staggered with the corresponding limiter 62 and the guide channel 712. The inner wall of the convex portion of the locking plate 72 blocks the upper side of the corresponding limiter 62 to prevent the limiter 62 from detaching upward from the guide channel 712, thereby locking the connection portion 61 and completing the locking of the filter element 6.

[0052] When unlocking the filter element 6, the buckle structure is unlocked by pressing, and the elastic force of the spring 74 to restore the deformation pops out the mounting plate 2 and rotates the mounting plate 2 to open the opening 12, while driving the locking structure 7 and the filter element 6 to swing to an inclined state, and the spring 74 pushes the locking plate 72 to move laterally away from the mounting plate 2 to the unlocking channel 721 and the corresponding limit member 62 and guide channel 712 which are arranged opposite to each other up and down. The limit member 62 can be disengaged upward through the corresponding unlocking channel 721 and guide channel 712, thereby unlocking the connecting part 61 and completing the unlocking of the filter element 1 from the installation space 22.

[0053] Therefore, the utility model can simultaneously realize the locking and unlocking of the filter element 6 and the locking and unlocking of the mounting plate 2 by utilizing the spring 74, thereby realizing the multifunctionality of the components on the basis of simplifying the structure.

[0054] In addition to the above-mentioned housing assembly structure, the utility model also provides a water purifier, see Figure 1-4 The water purifier includes a filter element 6, a locking structure 7 and the above-mentioned housing assembly structure. The filter element 6 and the locking structure 7 are both installed in the installation cavity 11 and close to the installation plate 2. The locking structure 7 is used to lock or unlock the filter element 6. In addition, the filter element 6 and the locking structure 7 rotate synchronously with the installation plate 2.

[0055] When disassembling and replacing the filter element 6, the water purifier of the utility model does not need to completely disassemble the housing, and only needs to rotate and pop out the mounting plate 2 through the cooperation of the buckle structure and the elastic member 3 to open the disassembly port of the filter element 6. The structure is simple and easy to operate. In addition, the filter element 6 and the locking structure 7 are close to the mounting plate 2 and installed in the mounting space 22 of the mounting plate 2, and the filter element 6 and the locking structure 7 swing along with the rotation of the mounting plate 2, so that when the filter element 6 is replaced, the filter element 6 swings to the outside of the housing 1, which is convenient for replacement.

[0056] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
