[0027] Such as Figures 1-7A highly stable wall-mounted water purifier capable of self-locking the filter element is shown, including a box body 1 and a hook piece 100 for hanging the box body 1. The hook piece 100 is fixed on the wall by means of expansion screws or the like. A filter element seat 2 is arranged at the upper end of the box body 1. Filter element installation cavities 3 are arranged on both the left and right sides of the filter element seat 2. Filter element assemblies 4 are installed in both the filter element installation cavities 3. A lift seat body 5 capable of moving up and down is arranged on the filter element seat 2 and between the two filter element installation cavities 3. Extension pressing plates 6 are arranged on both sides of the lift seat body 5. A pressing block 7 for pressing the filter element assembly 4 is arranged on the lower side of the outer end of the extension pressing plate 6. A hanging ear seat 8 is arranged at the rear side of the box body 1. A groove cavity 9 for hanging the hook piece 100 is arranged at the lower side of the hanging ear seat 8. A locking device for locking the hook piece 100 is arranged in the groove cavity 9. A transmission device is also connected between the hanging ear seat 8 and the lift seat body 5. When the hook piece 100 is hung and inserted into the groove cavity 9, the hook piece 100 pushes the transmission device, and the transmission device drives the lift seat body 5 to move down and drives the locking device to work to lock the hook piece 100.

[0028] The box body 1 is made of high-strength plastic or metal material to ensure structural strength and durability; the hook piece 100 is fixed on the wall by means of expansion screws or the like; the filter element seat 2 is formed by injection molding and installed at the upper end of the box body 1; the hanging ear seat 8 is fixed at the rear side of the box body 1, the groove cavity 9 opens downward, and the locking device and the transmission device are installed and debugged according to specific designs; when the user hangs the box body 1 into the groove cavity 9 through the hook piece 100, the hook piece 100 pushes the transmission device, and the transmission device drives the lift seat body 5 to move down, so that the pressing block 7 presses the filter element assembly 4, and at the same time, the locking device is triggered to lock the hook piece 100.

[0029] Thus, according to the above structure, the linkage operation of hanging the water purifier and fixing the filter element is realized. The user only needs one hanging action to complete the self-locking of the filter element and the locking of the box body at the same time, greatly improving the installation efficiency; the self-locking structure of the filter element effectively prevents the filter element from loosening and ensures stable filtering effect; the locking device of the box body enhances the reliability of equipment installation, reduces the risk of equipment falling due to external force, and improves the safety of user use.

[0030] In the present invention, a groove cavity 21 is provided on the filter element seat 2 and between two filter element installation cavities 3, and the lifting seat body 5 and the transmission device are arranged in the groove cavity 21; arranging the lifting seat body 5 and the transmission device in the groove cavity 21 makes the internal structure of the water purifier more compact, reduces the occupied space, and is beneficial to the miniaturization design of the product; at the same time, the groove cavity 21 plays a protective role for the internal components; in addition, an end cover (not shown in the drawings) can be covered on the upper end of the box body 1, so as to prevent dust, water stains, etc. from entering and affecting the normal operation of the components, improve the stability and service life of the equipment, and also make the appearance more simple and beautiful.

[0031] See Figures 4-7 As shown, the locking device includes a transverse guide rod 31 arranged in the groove cavity 9 and extending in the front-rear direction. A stop seat 32 slides back and forth on the transverse guide rod 31. A stop column 33 is arranged on the front side of the stop seat 32. A locking hole 34 for the stop column 33 to insert is arranged on the hook piece 100. A first spring 35 for keeping the stop seat 32 in the forward state is arranged on the rear side of the stop seat 32.

[0032] This locking device has a simple structure and realizes the automatic locking function through a mechanical structure; when the hook piece 100 is inserted into the groove cavity 9, without additional operation, the stop column 33 automatically inserts into the locking hole 34 under the action of the first spring 35 to lock the hook piece 100 and prevent it from moving, ensuring the firmness of the installation of the box body 1; at the same time, this mechanical locking method has high reliability, is not prone to failure, and has a low cost.

[0033] Further, the transmission device includes a hinge seat 41 arranged in the groove cavity 21. A transmission rocker 42 is hinged on the hinge seat 41. A first guide rod 43 extending in the left-right direction is arranged at the front end of the transmission rocker 42. A guide groove 44 extending in the front-rear direction is arranged on the lower side of the lifting seat body 5. The first guide rod 43 is movably arranged in the guide groove 44. A vertical guide rod 45 extending downward is arranged on the top wall of the groove cavity 9. A sliding plate 46 slides up and down on the vertical guide rod 45. A locking plate 47 is arranged at the lower end of the sliding plate 46. A locking notch 48 for the locking plate 47 to insert is arranged on the upper end of the stop seat 32. And when the locking plate 47 is inserted into the locking notch 48, the stop column 33 is not inserted into the locking hole 34. A second spring 49 is arranged at the upper end of the sliding plate 46. The transmission rocker 42 extends into the groove cavity 9 and is attached to the upper side of the sliding plate 46. The hook piece 100 is hung and inserted into the groove cavity 9 and can push up the sliding plate 46, so that the locking plate 47 is separated from the locking notch 48.

[0034] Inside the groove cavity 21, the hinge seat 41 is fixed to the filter element seat 2 by bolts. The transmission toggle plate 42 is hinged to the hinge seat 41 through a hinge shaft to ensure that the transmission toggle plate 42 can rotate flexibly. The first guide rod 43 is welded or fixed to the front end of the transmission toggle plate 42 by screw connection. The guide groove 44 is formed on the lower side of the lifting seat body 5. The first guide rod 43 cooperates with the guide groove 44 to convert the rotation of the transmission toggle plate 42 into the up and down movement of the lifting seat body 5. On the top wall of the groove cavity 9, the vertical guide rod 45 extends vertically downward through a fixing member. The sliding plate 46 realizes up and down sliding through a sliding sleeve sleeved on the vertical guide rod 45. The locking plate 47 is fixed to the lower end of the sliding plate 46. The locking notch 48 is formed on the upper end of the stop seat 32. One end of the second spring 49 is fixed to the upper end of the sliding plate 46, and the other end is fixed to the top wall of the groove cavity 9. During installation, ensure that the transmission toggle plate 42 extends into the groove cavity 9 and fits on the upper side of the sliding plate 46. When the hook piece 100 is inserted into the groove cavity 9, it pushes the sliding plate 46 upward. The sliding plate 46 drives the locking plate 47 to move upward, causing the locking plate 47 to disengage from the locking notch 48. At this time, the stop seat 32 moves forward under the action of the first spring 35, and the stop post 33 is inserted into the locking hole 34. At the same time, the sliding plate 46 moves upward and drives the lifting seat body 5 to move downward through the transmission toggle plate 42, and the pressing block 7 presses the filter element assembly 4.

[0035] Thus, through the ingenious mechanical structure design of this transmission device, the linkage of the hanging of the hook piece 100, the pressing of the filter element, and the locking of the hook is realized. Its structure is compact, the cooperation between components is precise, and the action transmission is stable and reliable. Through one hanging action, multiple key functions can be completed, the operation is simple, and the user experience is improved. At the same time, this pure mechanical transmission method does not require electric drive, reduces energy consumption and the risk of failure, and ensures the stability of the equipment during long-term use.

[0036] Furthermore, an extension seat 51 is provided at the upper end of the stop seat 32. A second guide rod 52 extending in the left-right direction is provided on the extension seat 51. An unlocking insertion rod 53 is inserted up and down at the upper end of the hanging ear seat 8. An inclined groove 54 is provided at the lower end of the unlocking insertion rod 53. The second guide rod 52 is movably disposed in the inclined groove 54.

[0037] When the hanging ear seat 8 is hung on the hook piece 100, since the stop seat 32 moves forward, under the cooperation of the second guide rod 52 and the inclined groove 54, the unlocking insertion rod 53 moves upward.

[0038] When it is necessary to disassemble the water purifier, press the unlocking insertion rod 53 downward. The unlocking insertion rod 53 drives the stop seat 32 to move backward through the cooperation of the inclined groove 54 and the second guide rod 52, causing the stop post 33 to disengage from the locking hole 34, thereby unlocking the hook piece 100.

[0039] Thus, the unlocking structure is reasonably designed and convenient to operate. The user can unlock the hook piece 100 by simply pressing down the unlocking rod 53, which facilitates the disassembly and maintenance of the water purifier. At the same time, the cooperation mode between the inclined slot 54 and the second guide rod 52 ensures the stability and reliability of the unlocking process, avoids the situation of unlocking failure or component damage caused by misoperation, and improves the maintainability of the device.

[0040] See Figure 5 As shown, there are limit baffles 61 spaced left and right in the slot cavity 9. A limit slot 62 for inserting the hook piece 100 is arranged below the limit baffle 61. The arrangement of the limit baffle 61 and the limit slot 62 provides accurate guidance for the insertion of the hook piece 100, avoids the deviation or misalignment of the hook piece 100 during the insertion process, ensures that the hook piece 100 can accurately cooperate with the locking device and the transmission device, and improves the accuracy and efficiency of installation. At the same time, the limiting structure enhances the stability of the hook piece 100 after installation, prevents it from shaking in the front-back and left-right directions, and further improves the firmness of the water purifier installation.

[0041] Furthermore, a guiding inclined surface 71 is arranged at the lower end of the limit slot 62. The arrangement of the guiding inclined surface 71 further optimizes the insertion process of the hook piece 100, enables the hook piece 100 to be inserted into the limit slot 62 more easily and quickly, reduces the installation difficulty, and improves the installation efficiency.

[0042] In the present invention, a number of guiding vertical rods 81 for guiding the up and down movement of the lifting seat body 5 are arranged in the groove cavity 21. The arrangement of the guiding vertical rods 81 provides stable guidance for the up and down movement of the lifting seat body 5, prevents the lifting seat body 5 from tilting or deviating during the movement, ensures that the pressing block 7 can accurately and evenly press the filter element assembly 4, and improves the reliability of the filter element self-locking.

[0043] See Figures 1-4 As shown, a vertically arranged rotating shaft is arranged at the inner end of the extending pressing plate 6. The rotating shaft is horizontally rotatably installed on the lifting seat body 5. This rotatable structure makes the installation and disassembly of the filter element assembly 4 more convenient. When the user replaces the filter element assembly 4, there is no need to disassemble the extending pressing plate 6. The user only needs to appropriately rotate the extending pressing plate 6 to complete the operation, which improves the user experience.

[0044] In the present invention, the pressing block 7 is made of rubber and can be firmly connected by means of bolt connection, bonding, etc.; the pressing block 7 made of rubber has good elasticity and flexibility, can closely fit the surface of the filter element assembly 4, increase the contact area, and improve the pressing effect; at the same time, the buffer performance of the rubber material can avoid hard damage to the filter element assembly 4 and protect the structural integrity of the filter element assembly 4; in addition, the rubber material has good wear resistance, can maintain good performance during long-term use, extends the service life of the pressing block 7, and reduces the maintenance cost.
