[0002] A water purifier is a water treatment device that deeply purifies water according to the requirements of water use. Its working principle is to introduce raw water into the filter cartridge. Under the action of pressure, water molecules and beneficial minerals flow out of the filter cartridge and undergo multi-stage filtration to become purified water, while harmful substances such as bacteria, colloids, rust, and suspended matter are retained in the filter cartridge, thereby achieving the effect of filtration and purification. Existing water purifiers can basically meet daily usage needs, but there are still some shortcomings that need to be improved.

DETAILED DESCRIPTION

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0023] See also Figure 1-11 A multifunctional filtering water purifier provided by an embodiment of the present invention includes a shell 1, a panel 2 is provided on the shell 1, a water outlet 3 is provided at the lower end of the panel 2, and a base 4 is provided at the bottom of the shell 1 facing the water outlet 3. It also includes: a groove 5, which is provided at the center of the upper end of the base 4, and a coupler 6 is provided therein for lifting and lowering; a cover 7, which is rotatably provided on the base 4 for covering the groove 5; a driving assembly, which is used to drive the cover 7 to rotate to open the groove 5 first, and then drive the coupler 6 to rise and extend out of the groove 5, or reversely drive the coupler 6 to first descend and retract into the groove 5, and then drive the cover 7 to rotate to cover the groove 5.

[0024] Specifically, the front of the shell 1 is set as a water receiving area, and the back is set as a filter element installation area. Multiple filter elements are installed for multi-stage filtration function. The filter elements can be freely disassembled and replaced. The specific details are prior art and will not be repeated here. The panel 2 is used for interactive operation to control functions such as water addition, water stop, heating, and timing. The water outlet 3 is set to discharge water downward. A soft water pipe is provided between the shell 1 and the water outlet 3, which is omitted in the figure. The base 4 is used to support various water receiving containers. The depth of the groove 5 is sufficient to fully accommodate the coupler 6. The coupler 6 is used to dock with the interface at the bottom of the kettle 14 to realize power supply, and then start heating through the control button on the kettle 14. The cover 7 is on When the base 4 is horizontal, that is, it rotates in the horizontal plane, the rotation axis of the cover 7 is set on one side of the groove 5, and the cover 7 can completely cover the upper end of the groove 5 or completely avoid the upper end of the groove 5 when rotating; the driving component drives the rotation of the cover 7 and the lifting and lowering of the coupler 6 in a specific sequence, specifically: when the coupler 6 is at the lowest position of the lifting stroke to be completely received in the groove 5, the driving component drives the cover 7 to rotate first to completely open the groove 5, and then drives the coupler 6 to rise and extend out of the groove 5. After the driving component reverses the drive, it first drives the coupler 6 to descend to completely receive the groove 5, and then drives the cover 7 to rotate to a position that completely covers the groove 5. In actual use, the present technical solution can realize that the cover 7 is first rotated to open the groove 5 under the sequential driving of the driving assembly, and then the coupler 6 is raised and extended out of the groove 5 for normal use. When the coupler 6 is idle, the coupler 6 can be driven to descend and retract into the groove 5, and then the cover 7 is rotated to block the groove 5, thereby preventing the coupler 6 from being wetted by water droplets or external factors, ensuring safe use, and making the upper surface of the base 4 flush to support other containers for collecting water.

[0025] Compared with the prior art, the multifunctional filtering water purifier proposed in the embodiment of the present invention is provided with a cover 7, and under the sequential driving of the driving component, the cover 7 can be first rotated to open the groove 5, and then the coupler 6 can be raised and extended out of the groove 5 for normal use. During the idle period of the coupler 6, the coupler 6 can be driven to descend and retract into the groove 5, and then the cover 7 can be rotated to block the groove 5, thereby preventing the coupler 6 from being wetted by water droplets or external factors, ensuring safe use, and making the upper surface of the base 4 flush to support other containers for water collection.

[0026] As the preferred technical solution of this embodiment, the driving assembly includes a first rack 8 movably arranged in the base 4, the first rack 8 is meshedly connected to the first gear 9, the lower end of the coupler 6 is coaxially connected to a threaded column 10, and the outer side of the threaded column 10 is connected to the hollow thread of the first gear 9. Specifically, the groove 5 is preferably polygonal, and the lower end of the coupler 6 is set to a polygonal body matching the groove 5, so that the coupler 6 is only lifted and lowered in the groove 5, and then when the first rack 8 links the first gear 9 to rotate, the hollow of the first gear 9 and the threaded column 10 have a threaded feeding effect to drive the coupler 6 to rise and fall.

[0027] As a preferred technical solution of this embodiment, the driving assembly also includes a second rack 11 movably arranged in the base 4, and the second rack 11 is meshedly connected with a second gear 12 coaxially connected to the rotating shaft of the cover 7.

During the transmission process of the first rack 8, the first rack 8 will pass through one side of the second gear 12, but will not interfere with the second gear 12; there is a time interval between the meshing transmission of the first gear 9 and the first rack 8 and the meshing transmission of the second gear 12 and the second rack 11, specifically: coupling When the coupler 6 is completely retracted into the groove 5, the motor 13 drives the movement of the first rack 8, causing the second rack 11 to move synchronously. The second rack 11 first engages and transmits the second gear 12, causing the cover 7 to rotate and gradually leave the position of blocking the groove 5. At least when the cover 7 completely avoids the top of the groove 5, the first rack 8 engages and transmits with the first gear 9, thereby triggering the threaded column 10 to drive the coupler 6 to rise and extend out of the groove 5; on the contrary, when the motor 13 drives the first rack 8 back, the first rack 8 first engages and transmits the first gear 9, thereby triggering the threaded column 10 to drive the coupler 6 to descend and be retracted into the groove 5, and then the second rack 11 engages and transmits with the second gear 12, causing the cover 7 to rotate to block the groove 5 again.

[0029] In another embodiment proposed by the present invention, the multifunctional filtering water purifier also includes a hot water kettle 14 arranged on the base 4, and a pot lid 15 is elastically hinged on the hot water kettle 14, and a limiting component for limiting the rotation of the pot lid 15 is provided on the hot water kettle 14. The cancellation action of the limiting component is linked with the rotation of the cover 7 to open the groove 5. Specifically, the pot lid 15 is elastically hinged to the upper end of the hot water kettle 14 through a torsion spring, thereby maintaining an elastically closed state. When the pot lid 15 is opened, it tends to close under the elastic force; a spout is provided on one side of the hot water kettle 14, and a handle is provided on the other opposite side. A control button for controlling the heating to be turned on is provided on the handle, and the side of the pot lid 15 close to the handle is set as a hinge point; the limiting component limits the rotation of the pot lid 15 when the pot lid 15 is fully opened; after the cover 7 completely avoids the groove 5, the limiting component is linked to cancel the limiting effect. At this time, the coupler 6 is normally connected to the bottom interface of the hot water kettle 14, and the pot lid 15 is automatically closed, realizing automatic closed-lid heating after the hot water kettle 14 is connected to water.

[0030] As a preferred technical solution of this embodiment, the limiting assembly includes a lifting groove 16 provided in the kettle 14 entity, a control rod 17 is elastically provided in the lifting groove 16, a first hook 18 is provided on the upper side wall of the control rod 17, and an interactive groove 19 for the first hook 18 to move is provided on the side wall of the kettle 14. A pressure handle 20 is provided on the pot cover 15, and a second hook 21 matching the first hook 18 is provided on the pressure handle 20. Specifically, a spring is provided on the top surface of the lifting groove 16, and the spring keeps pushing the control rod 17 downward, so that the lower end of the control rod 17 extends out of the bottom of the kettle 14, and the first hook 18 is at the lowest point of the lifting stroke; When the first hook 18 is at the lowest point of the lifting stroke, the pressing handle 20 rotates with the pot lid 15 to the fully open position so that the second hook 21 is smoothly hooked with the first hook 18; the interactive groove 19 is connected to the outer wall of the hot water kettle 14, and when the pot lid 15 is rotated to the fully open position, the side of the pressing handle 20 where the second hook 21 is provided is fitted to the outer side of the interactive groove 19, and the second hook 21 is inserted into the interactive groove 19 to cooperate with the first hook 18; when the lower end of the control rod 17 is pushed upward, the control rod 17 resists the elastic force to drive the first hook 18 to move upward. At this time, the first hook 18 and the second hook 21 are separated from each other and cannot play a restrictive role.

[0031] As a preferred technical solution of this embodiment, an active cavity 22 for the cover 7 to move is provided on the base 4, and the active cavity 22 covers the groove 5. Specifically, the active cavity 22 is provided in the base 4 entity and is close to the top surface of the base 4. The active cavity 22 covers the groove 5, that is, the movable range of the cover 7 covers the groove 5, ensuring that the cover 7 can completely cover the groove 5 in the specified position.

[0032] As a preferred technical solution of this embodiment, a through hole 23 connecting to the active cavity 22 is provided on the base 4, and the lower end of the control rod 17 can move through the through hole 23 to enter the active cavity 22. The edge of the cover 7 is chamfered and can be wedge-fitted with the lower end of the control rod 17. Specifically, the lower end of the control rod 17 is chamfered or spherical to meet the wedge-shaped fit with the edge of the cover 7; when the kettle 14 is placed on the base 4 with the spout facing the shell 1 and with the center corresponding to the coupler 6, the lower end of the control rod 17 is exactly corresponding to the through hole 23, and the lower end of the control rod 17 extending from the bottom of the kettle 14 can pass through the through hole 23 to enter the active cavity 22. When the kettle 14 is in operation, the first gear 18 is engaged with the second gear 11 and the second gear 12, and the first gear 18 is engaged with the first gear 11. When the kettle 14 is in operation, the first gear 18 is engaged with the second gear 11 and the second gear 12, and the first gear 18 is engaged with the second gear 11. When the kettle 14 is in operation, the first gear 18 is engaged with the second gear 11 and the second gear 12, and the first gear 12 is engaged with the first gear 11 and the second gear 12, and the first gear 12 ...

[0033] As the preferred technical solution of this embodiment, a boss 24 is provided on the base 4, and a clamping ring 25 matching the boss 24 is provided at the bottom of the kettle 14. A positioning piece 26 is provided on the inner side of the clamping ring 25, and a positioning groove 27 matching the positioning piece 26 is provided on the boss 24. Specifically, the boss 24 is preferably circular; the clamping ring 25 is the actual supporting structure at the bottom of the kettle 14. The setting of the clamping ring 25 prevents the control rod 17 extending from the bottom of the kettle 14 from directly contacting the planar support surface; the setting of the positioning piece 26 and the positioning groove 27 ensures that the kettle 14 is accurately placed on the base 4 with the spout facing the shell 1. Furthermore, a pressure sensor for controlling the start and stop of the motor 13 is provided in the base 4. The positioning members 26 and the positioning slots 27 are preferably two and symmetrically arranged. The positive and negative electrodes of the pressure sensor are respectively arranged in the two positioning slots 27 to maintain an open circuit, and the inner wall of the collar 25 is provided with a conductive sheet extending to the two positioning members 26. Thus, only when the kettle 14 is correctly placed on the base 4, the positive and negative electrodes of the pressure sensor are connected through the conductive sheet. The pressure sensor operates to monitor the weight on the base 4. After the kettle 14 is filled with water to a certain amount, the pressure When the sensor reaches the trigger threshold, it controls the motor 13 to start, thereby opening the cover 7, extending and connecting the coupler 6, and automatically closing the pot lid 15. In addition, the water spout 3 will stop discharging water when the motor 13 is just started, thereby achieving automatic closing and heating of the kettle 14 after receiving water. In addition, when the kettle 14 is removed, the pressure sensor is disconnected and the generator 13 is reversely driven again, thereby achieving automatic reset of the cover 7 and the coupler 6. In addition, when other containers are used to receive water, the pressure sensor does not operate. The circuit control for the pressure sensor to trigger the operation of the motor 13 is existing technology and will not be described in detail. It is not drawn in the figure. The figure only shows the positive and negative electrodes of the pressure sensor in the positioning groove 27 and the conductive sheet on the inner wall of the clamping ring 25.

[0034] When the lid 15 is closed, sufficient space is required above the kettle 14 for movement. However, when the kettle 14 is placed on the base 4, the movement of the lid 15 is likely to interfere with the panel 2. Therefore, reducing the height of the kettle 14 will undoubtedly significantly reduce the capacity of the kettle 14, while increasing the height of the panel 2 will undoubtedly increase the overall space occupied by the water purifier device, reducing its practicality. The following embodiment is proposed to improve this problem by folding the panel 2.

[0035] In another embodiment of the present invention, the panel 2 is hinged on the shell 1, and a push-pull member 28 is movably provided on the shell 1. A sliding pin 29 is provided at one end of the push-pull member 28. A linkage frame 30 matching the sliding pin 29 is provided on the back side of the panel 2. The other end of the push-pull member 28 is linked to the first rack 8 through a linkage assembly. Specifically, the linkage assembly includes a linkage shaft 32 coaxially connected to the drive gear 31. The push-pull member 28 is fixedly provided with a third rack 33 at one end away from the panel 2. The upper end of the linkage shaft 32 is coaxially connected to the third rack 33. The third gear 34 is meshed with three racks 33; the panel 2 rotates and the push-pull member 28 moves horizontally. The setting of the sliding pin 29 and the linkage frame 30 avoids interference between the rotation of the panel 2 and the horizontal movement of the push-pull member 28; the linkage frame 30 includes an upper linkage part and a lower sliding part. The sliding pin 29 passes through the upper linkage part of the linkage frame 30 to link the panel 2 to rotate, and the sliding pin 29 passes through the lower sliding part of the linkage frame 30 to maintain the rotation angle of the panel 2, which is used to match the continuous movement of the push-pull member 28. When the folding of the panel 2 is complete, the lid 15 is automatically closed by the sliding pin 29, and the folding of the panel 2 is completed.

[0036] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
