[0002] As people's quality of life continues to improve, they begin to use water purifiers to get better water quality. The main component of the water purifier, the filter element, is a consumable part, so the after-sales maintenance and replacement of the filter element have become more frequent. However, the replacement of the filter element on the market is relatively troublesome, and due to the influence of various factors such as water pressure, users have varying degrees of difficulty in replacing the filter element. Either the filter element cannot be removed, or the filter element cannot be installed, or the filter element is installed but not installed properly. These problems often occur, affecting the replacement experience of the majority of users, and disassembling and replacing the filter element has become a relatively difficult task. Summary of the invention

[0027] The push block 5 is arranged on the top of the filter bottle 2, and one side of the push block 5 has an installation push inclined surface 51, and the other opposite side of the transmission block has a disassembly push inclined surface 52; in this embodiment, the outer edge of the push block 5 is a parallelogram, one side of the inclined surface is the installation push inclined surface 51, and the other side of the inclined surface is the disassembly push inclined surface 52; the outer flat side of the push block 5 has a mounting groove 53;

[0028] A driving motor 3 is arranged above the accommodating cavity;

[0029] The driving cam 4 connected to the output shaft of the driving motor is provided with a mounting driving block 41 that can cooperate with the mounting push inclined surface, and a disassembly driving block 42 that can cooperate with the disassembly pushing inclined surface. The mounting driving block 41 is provided with a driving inclined surface 411 that can cooperate with the mounting push inclined surface; the disassembly driving block 42 is provided with a disassembly inclined surface 421 that can cooperate with the disassembly pushing inclined surface. The driving cam 4 can rotate forward or reverse under the drive of the driving motor 3. When the driving cam 4 rotates forward, the driving inclined surface 411 on the mounting driving block 41 can cooperate with the mounting push inclined surface 51 on the pushing block 5, thereby driving the pushing block and the filter bottle to move toward the accommodating chamber; when the driving cam 4 reverses, the disassembly inclined surface 421 on the disassembly driving block 42 can cooperate with the disassembly pushing inclined surface 53 on the pushing block, thereby driving the pushing block and the filter bottle to move away from the accommodating chamber; in addition, the mounting driving block 41 is provided with a limiting protrusion 412 that cooperates with the installation groove 53.

[0030] The main body 1 is provided with a main control board 10 electrically connected to the drive motor 3 and used to control the forward or reverse rotation of the drive motor 3. A filter bottle positioning groove 12 is provided at the bottom of the accommodating chamber 11, and a trigger button switch 6 is provided at the lower part of the inner wall of the accommodating chamber 11. When the filter bottle 2 is preset in the filter bottle positioning groove 12, the outer wall of the filter bottle 2 can start the trigger button switch 6, and the trigger button switch 6 is electrically connected to the main control board 10. The main control board 10 can control the drive motor to rotate forward after receiving the signal of the trigger button switch, thereby driving the filter bottle to enter the accommodating chamber 11.

[0031] A positioning groove 13 is provided at the lower part of the accommodating cavity 11 , and a boss 21 which can cooperate with the positioning groove is correspondingly provided at the bottom of the filter bottle 2 .

[0032] The main body 1 is also provided with a removal key switch 7 electrically connected to the main control board. The main control board 10 can control the driving motor to reverse after receiving the signal of the removal key switch 7, thereby driving the filter bottle away from the accommodating chamber. The upper part of the inner wall of the accommodating chamber 11 is provided with a filter bottle installation in place trigger switch 8, which is also electrically connected to the main control board 10. The main control board can control the driving motor to stop rotating after receiving the signal of the filter bottle installation in place trigger switch 8.

[0033] A filter bottle mounting seat assembly 9 that cooperates with the filter bottle is provided at the top of the accommodating chamber 11. A water interface 91 is provided on the filter bottle mounting seat assembly 9, and a water transfer interface 22 is correspondingly provided on the filter bottle 2. When the filter bottle enters the accommodating chamber, the water transfer interface on the filter bottle can be exactly matched and connected with the water interface on the bottle mounting seat assembly.

[0034] Limiting grooves 92 are provided on both sides of the filter bottle mounting seat assembly 9, and limiting posts 23 are provided on both sides of the filter bottle 2. When the filter bottle 2 enters the accommodating cavity 11, the limiting posts 23 on the filter bottle 2 just fit into the limiting grooves 92 on both sides of the filter bottle mounting seat assembly 9. The filter bottle mounting seat assembly 9 is also provided with arc-shaped guiding fixing ribs 93, and the top of the filter bottle 2 is provided with an arc groove 24 that can cooperate with the guiding fixing ribs 93. When the filter bottle 2 enters the accommodating cavity 11, the guiding fixing ribs 93 on the filter bottle mounting seat assembly can guide and slide in the arc groove 24 of the filter bottle.

[0035] When pre-installing the filter bottle, the filter bottle is first placed obliquely into the positioning groove 13 at the bottom of the accommodating chamber 11. When the filter bottle is close to the trigger button switch 6, the control board controls the driving motor to rotate forward, and the driving motor 3 drives the driving cam 4 to rotate. The installation driving block 41 on the driving cam 4 rotates accordingly. The driving inclined surface 411 on the installation driving block 41 can cooperate with the installation pushing inclined surface 51 on the pushing block 5, thereby driving the pushing block and the filter bottle to move toward the accommodating chamber. See Figure 5 As shown; due to the limited grooves 32 and guide fixing ribs 93 on both sides of the filter bottle mounting seat assembly 9, it is effectively guaranteed that the filter bottle can play an effective guiding role when it is installed, so that the filter bottle can be installed in place, and the water transfer interface 22 of the filter bottle can be smoothly inserted into the water interface 91 on the filter bottle mounting seat assembly 9. After the filter bottle is installed in place, the filter bottle installation in place trigger switch 8 is triggered, the main control board receives the signal, and gives the drive motor a stop signal, the drive motor stops, and the filter bottle is installed in place, see Figure 4 As shown, at this time, the limiting protrusion 412 on the installation drive block 41 is just inserted into the installation groove 53 on the outer flat edge of the push block 5, see Figure 6 shown.

[0036] When the filter bottle is to be removed, the removal button switch 7 on the main body is pressed. After receiving the signal, the main control board controls the driving motor to rotate in the opposite direction, and the disassembly driving block 42 on the driving cam 4 rotates accordingly. The disassembly inclined surface 421 on the disassembly driving block 42 can cooperate with the disassembly pushing inclined surface 52 on the pushing block 5, thereby driving the pushing block and the filter bottle to move away from the accommodating chamber. When the filter bottle is separated from the trigger button switch 6, the main control board receives the signal and controls the driving motor to stop rotating, completing the disassembly of the filter bottle. The user can easily take it down. Figure 7 That is, the functions of automatic installation and disassembly of the filter element are completed.

[0037] After the filter bottle is assembled, due to pressure and other factors, there are great requirements for the driving force of the drive motor. The motor of this system must meet certain requirements and must have a large torque after being combined with the filter element drive wheel. The torque must be greater than 1Kg. The drive wheel must be made of a relatively strong material such as POM or PC nylon to obtain better strength. In order to keep the filter element drive balanced, in this embodiment, the drive teeth are left-right symmetrical teeth. The filter bottle is installed in place. The trigger switch 8 and the trigger button switch 6 use a micro switch.
