[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0039] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments:

[0040] like Figure 1-5 As shown, a novel lifting handwashing station includes a washbasin assembly 1 and a support assembly 2. A lifting mechanism is provided between the washbasin assembly 1 and the support assembly 2. The lifting mechanism is used to drive the washbasin assembly 1 to move up and down relative to the support assembly 2.

[0041] The lifting mechanism includes a transmission assembly 3, a drive assembly 4, and push rod assemblies 5 arranged opposite to each other on the left and right sides;

[0042] The transmission assembly 3 includes a linkage rod 31 and a right-angle coupling 32. The two ends of the linkage rod 31 are respectively provided with right-angle couplings 32, and the right-angle couplings 32 are fixedly connected to the washbasin assembly 1.

[0043] The push rod assembly 5 includes a lead screw 51 and a cylinder 52. One end of the lead screw 51 is threadedly connected to the cylinder 52 inside the cylinder 52, and the other end is connected to the linkage rod 31 via a right-angle coupling 32. The cylinder 52 is fixedly connected to the bracket assembly 2.

[0044] The drive assembly 4 includes a worm gear 41, a worm 42 and a reducer 43. The worm gear 41 is non-rotatably mounted on the linkage 31.

[0045] The worm 42 is connected to the drive end of the reducer 43, and the worm 42 is meshed with the worm wheel 41.

[0046] The speed reducer 43 is fixedly connected to the washbasin assembly 1;

[0047] It also includes a control module disposed on the washbasin assembly 1, which is electrically connected to the drive assembly 4.

[0048] In this embodiment, a structural design is adopted to drive the push rods on both sides to move synchronously, ensuring that the hand basin assembly 1 rises and falls smoothly and preventing jamming or shaking due to asynchronous rising and falling on both sides; at the same time, a worm gear reducer with self-locking function is used as the drive component 4 to effectively prevent the hand basin assembly 1 from falling when the power is cut off or when it is subjected to external force, ensuring the safety and reliability of the hand basin and thus avoiding injury to the user.

[0049] Lifting control principle: When the washbasin assembly 1 needs to be raised, the control module controls the reducer 43 to drive it. The reducer 43 rotates in the forward direction, which drives the linkage rod 31 to rotate through the worm gear 41 and worm 42. Then, through the right-angle coupling 32, it drives the lead screw 51 of the push rod assembly 5 on both sides to rotate synchronously, thereby driving the washbasin assembly 1 to rise. Conversely, the reducer 43 rotates in the reverse direction.

[0050] Furthermore, such as Figure 3 , 5 As shown, in order to improve the overall stability of the washbasin and prevent the washbasin assembly 1 from shaking or vibrating relative to the support assembly 2, a protective sleeve assembly 6 is provided on the outer side of the push rod assembly 5. The protective sleeve assembly 6 includes an inner protective sleeve 61 and an outer protective sleeve 62.

[0051] One end of the inner sheath 61 is movably connected to the outer sheath 62, and the other end is fixedly connected to the washbasin assembly 1. The end of the outer sheath 62 away from the inner sheath 61 is fixedly connected to the bracket assembly 2.

[0052] Furthermore, such as Figure 3 , 5 As shown, in order to reduce the gap between the outer sheath 62 and the inner sheath 61 and improve the lifting stability, a plurality of bushings 7 are provided at the movable joint of the outer sheath 62 and the inner sheath 61, and the bushings 7 are connected to the outer sheath 62 and / or the inner sheath 61.

[0053] Furthermore, such as Figure 1 , 3 As shown in Figure 4, in order to improve aesthetics and protect the lifting mechanism, an upper baffle 8 and a lower baffle 9 are provided on the front side between the washbasin assembly 1 and the bracket assembly 2, and the upper baffle 8 and the lower baffle 9 are connected to the bracket assembly 2.

[0054] Furthermore, such as Figure 1 , 3 As shown in Figures 4 and 5, the washbasin assembly 1 includes a washbasin 11 and a lifting frame 12 arranged sequentially from top to bottom.

[0055] The washbasin 11 is connected to the lifting frame 12, and a faucet 10 is provided on the washbasin 11; the lifting frame 12 is connected to the support assembly 2 through a lifting mechanism.

[0056] In this embodiment, the reducer 43, the upper sheath, and the right-angle coupling 32 are all fixedly connected to the lifting frame 12.

[0057] Furthermore, such as Figure 3 As shown, in order to enable the washbasin to have storage function and improve its practicality, a storage cavity 100 is provided inside the lifting frame 12, and a cabinet door 20 is provided at the front opening of the storage cavity 100.

[0058] Furthermore, such as Figure 1 , 3 As shown, in order to meet the needs of special groups and improve ease of use, a handrail 30 is also provided on the front side of the lifting frame 12, and the handrail 30 is detachably connected to the lifting frame 12.

[0059] Furthermore, such as Figure 1As shown, in order to facilitate the lifting and lowering of the washbasin, the control module includes a control board 40 and control buttons on the control board 40.

[0060] In this embodiment, the control buttons include an up button 50 and a down button 60. Pressing the button drives the movement up or down, and releasing the button stops the movement up or down.

[0061] Furthermore, such as Figure 3 As shown, in order to facilitate disassembly, assembly and maintenance of the linkage rod 31, the linkage rod 31 includes a connecting rod 311 with coaxial ends, and the two connecting rods 311 are connected by a detachable sleeve 312.

[0062] For those skilled in the art, various other corresponding changes and modifications can be made based on the technical solutions and concepts described above, and all such changes and modifications should fall within the protection scope of the claims of this utility model patent.
