A first screw passes through the first screw hole and is connected to the first threaded hole at the column portion, so that the rotating block can rotate 360 ​​degrees in the first screw hole with the first screw as the axis.

[0013] Furthermore, the column portion forms a limiting platform along the circumference of its outer wall surface.

[0014] Furthermore, the slide rod body is provided with a U-shaped circular arc hole along its axial direction, and the opening of the U-shaped circular arc hole causes a side wall of the slide rod body to be disconnected to form a sliding groove; the rotating shaft is installed in the U-shaped circular arc hole of the slide rod body;

[0015] The through hole on the shower seat body is sleeved outside the slide rod body, and through the cooperation between the fan-shaped arc surface on the rotating block and the bidirectional spiral groove on the rotating shaft, when the rotating shaft rotates 360 degrees, the rotating block is driven to slide up and down in the sliding groove of the slide rod assembly.

[0016] Furthermore, the bidirectional spiral groove on the rotating shaft includes a left spiral groove and a right spiral groove, and the end of the left spiral groove is tangent to the end of the right spiral groove, so that smooth transition areas are formed at the upper and lower ends of the rotating shaft, respectively, thereby forming a connection conversion notch arranged at the upper and lower ends of the rotating shaft;

[0017] The sector-shaped arc surface portion on the rotating block is formed with a guide opening that matches the connection conversion notch.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When the user needs to adjust the height of the shower, he first operates the switch assembly to transmit the start signal to the drive assembly to drive the shaft to rotate. Since the shaft is provided with a bidirectional spiral groove, and the rotating block in the shower seat assembly closely cooperates with it, as the shaft rotates, the rotating block moves along the track of the bidirectional spiral groove.

DETAILED DESCRIPTION

[0044] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0045] The following is combined with Figure 1 To Attachment Fig.12 And specific embodiments, the present invention is described in detail:

[0046] like Figure 1-12 As shown, the present invention provides a shower seat lifting device, which includes a slide rod assembly 1, a drive assembly 2, a shower seat assembly 3 and a switch assembly 4.

[0047] The slide bar assembly 1 includes a slide bar body 10 and a rotating shaft 11 rotatably mounted in the slide bar body 10 . A bidirectional spiral groove 111 is provided on the rotating shaft 11 , which can convert rotational motion into linear motion.

[0048] The driving assembly 2 is installed at one end of the slide rod assembly 1 and is in transmission connection with the rotating shaft 11 . The driving assembly 2 provides power for the device and drives the rotating shaft 11 to rotate.

[0049] The shower seat assembly 3 includes a shower seat body 30 and a rotating block 31 installed on the shower seat body 30; wherein the shower seat body 30 is sleeved and installed on the sliding assembly 1, and the lifting and lowering of the shower seat assembly 3 is achieved through the cooperation between the rotating block 31 and the bidirectional spiral groove 11 on the rotating shaft 11; the shower seat assembly 3 is used to install a shower, and when the rotating shaft 11 rotates, the shower seat assembly 3 drives the shower to rise and fall smoothly and accurately along a spiral trajectory, thereby meeting the requirements of different users for the height of the shower.

[0050] The switch assembly 4 is mounted on the slide bar body 10 and is electrically connected to the drive assembly 2 to control the opening and closing of the drive assembly 2. In this embodiment, the switch assembly 4 is fixedly mounted on the slide bar body 10 by screws or the like.

[0051] When the user needs to adjust the shower height, the switch assembly 4 is first operated to transmit the start signal to the drive assembly 2 to drive the rotating shaft 11 to rotate. Since the rotating shaft 11 is provided with a bidirectional spiral groove 111, and the rotating block 31 in the shower seat assembly 3 is closely matched therewith, as the rotating shaft 11 rotates, the rotating block 31 will move along the track of the bidirectional spiral groove 111. Since the shower seat body 30 is sleeved on the slide bar assembly 1 and connected to the rotating block 31, the movement of the rotating block 31 in the spiral groove will drive the shower seat body 30 to rise and fall along the slide bar assembly 1, thereby accurately adjusting the shower height to meet the personalized needs of the user.

[0052] Compared with the traditional manual method of adjusting the height of the shower seat, the shower seat lifting device in the present invention uses the synergistic effect of the driving component 2 and the switch component 4. The user only needs to press a button to realize the automatic lifting of the shower seat, which greatly improves the convenience of adjustment and is especially convenient for the elderly, children and people with physical disabilities.

[0053] At the same time, the precise matching design of the bidirectional spiral groove 111 and the rotating block 31 enables the shower seat assembly 3 to be raised and lowered along the spiral trajectory, achieving stepless lifting and more precise height control, ensuring that the user can adjust the shower to the most comfortable position every time.

[0054] In addition, the heights of different users vary greatly. The height adjustability of the shower head of the present invention can meet the different needs of users of different heights for shower head height. Whether a tall user needs to raise the shower head to avoid bending over, or a short user needs to lower the shower head for easy access, it can be easily achieved, thereby improving the overall comfort of showering.

[0055] Further, in some specific embodiments, a through hole 301 for accommodating the slide bar assembly 1 is provided on the shower seat body 30, and a first screw hole 302 is provided on a side wall of the through hole 301, and the opening direction of the first screw hole 302 is perpendicular to the side wall of the through hole 301. Specifically, the first screw hole 302 on the shower seat body 30 is a light hole, and its main function is to provide a positioning and accommodating space for the installation of the rotating block 31, and at the same time allow the rotating block 31 to rotate therein.

[0056] The rotating block 31 includes a fan-shaped arc surface 311 and a columnar portion 312 disposed at a non-open end of the fan-shaped arc surface 311. A first threaded hole 313 is provided along the axial direction of the columnar portion 312. A first screw 32 passes through the first screw hole 302 and is connected to the first threaded hole 313 at the columnar portion 312, so that the rotating block 31 can rotate 360 ​​degrees in the first screw hole 313 with the first screw 32 as the axis. The first threaded hole 313 on the rotating block 31 is used to cooperate with the first screw 32, and the rotating block 31 is fixed to the shower seat body 30 by screwing the first screw 32 in.

[0057] During assembly, first align the rotating block 31 with the first screw hole 302 of the shower seat body 30, so that the first threaded hole 313 of the rotating block 31 is aligned with the first screw hole 302. Then, the first screw 32 passes through the first screw hole 302 of the shower seat body 30 and is screwed into the first threaded hole 313 of the rotating block 31. As the first screw 32 is gradually tightened, the rotating block 31 is fixed on the shower seat body 30. This connection method ensures that during normal use of the device, even in the face of water flow impact, external forces generated by daily operations, etc., the rotating block 31 will not easily separate from the shower seat body 30, maintaining the integrity and stability of the structure. At the same time, the rotating block 31 can rotate 360 ​​degrees with the first screw 32 as the axis, which satisfies its flexible rotation function required in the process of cooperating with the rotating shaft 11 to realize the lifting and lowering of the shower seat assembly 3, ensuring that the entire lifting and lowering action can be carried out smoothly.

[0058] In some more specific embodiments, a limiting platform 314 is formed on the circumference of the outer wall of the column portion 312, that is, an annular protrusion is formed on the outer wall of the column portion 312, which serves as a limiting platform 314 to limit the axial displacement of the rotating block 31 in the first screw hole 302, thereby ensuring that the rotating block 31 will not move along the axial direction of the first screw 32 during rotation, so that it can only rotate 360 ​​degrees within the space limited by the first screw hole 302, thereby ensuring the stability and accuracy of the rotation.

[0059] At the same time, due to the presence of the stopper 314, the rotating block 31 will not be over-tightened and lose its ability to rotate after tightening the first screw 32, but can freely rotate 360 ​​degrees in the first screw hole 302 with the first screw 32 as the axis, realizing its function in the shower seat lifting device, that is, cooperating with the bidirectional spiral groove 111 on the rotating shaft 11 to drive the shower seat assembly 3 to achieve lifting action. In addition, this rotating connection method also facilitates the adjustment of the relative position of the rotating block 31 and other components during installation and use.

[0060] Furthermore, in some specific embodiments, the slide rod body 10 is provided with a U-shaped arc hole 101 along its axial direction, and the opening of the U-shaped arc hole 101 disconnects one side wall of the slide rod body 10 to form a sliding groove 102; the rotating shaft 11 is installed in the U-shaped arc hole 101 of the slide rod body 10.

[0061] The through hole 301 on the shower seat body 30 is sleeved outside the slide rod body 10, and through the cooperation between the fan-shaped arc surface 311 on the rotating block 31 and the bidirectional spiral groove 111 on the rotating shaft 11, when the rotating shaft rotates 360 degrees, the rotating block 31 is driven to slide up and down in the sliding groove 102 of the slide rod assembly 1.

[0062] When the shower height needs to be adjusted, the rotating shaft 11 rotates 360 degrees in the U-shaped circular arc hole 101 of the slide rod body 10. Since the rotating shaft 11 is provided with a bidirectional spiral groove 111, and the fan-shaped arc surface 311 on the rotating block 31 in the shower seat assembly 3 is closely matched with it, as the rotating shaft 11 rotates, the rotating block 31 will be constrained by the spiral trajectory of the spiral groove 111. At the same time, the shower seat body 30 is sleeved outside the slide rod body 10 through the through hole 301 thereon, providing a guide support for the up and down movement of the shower seat body 30. When the rotating block 31 is driven by the rotation of the rotating shaft 11, its fan-shaped arc surface 311 moves along the bidirectional spiral groove 111. Since the rotating block 31 is fixed on the shower seat body 30, the rotating block 31 will slide up and down in the sliding groove 102 of the slide rod assembly 1, thereby driving the shower seat body 30 to achieve a lifting action along the slide rod body 10, meeting the different needs of users for the shower height.

[0063] It can be seen that the U-shaped arc hole 101 of the slide rod body 10 provides a stable installation position for the rotating shaft 11, ensuring that the rotating shaft 11 will not deviate during the rotation process, thereby ensuring the stability of power transmission. At the same time, the through hole 301 of the shower seat body 30 is sleeved outside the slide rod body 10, and the sliding design of the rotating block 31 in the sliding groove 102 allows the shower seat assembly 3 to be reliably guided during the lifting process, avoiding unstable phenomena such as shaking and tilting, thereby enhancing the safety of use.

[0064] Furthermore, in some specific embodiments, the bidirectional spiral groove 111 on the rotating shaft 11 includes a left spiral groove and a right spiral groove, and the end of the left spiral groove is tangent to the end of the right spiral groove, so that a smooth transition area is formed at the upper and lower ends of the rotating shaft 11, respectively, and then a connecting conversion notch 112 is formed at the upper and lower ends of the rotating shaft 11; in other words, from a cross-sectional view, it is like two spiral grooves of different rotation directions are smoothly connected together at the ends to form a shape in which the spiral grooves are tangent. The existence of this transition area is to provide a space for the rotating block 31 to change the direction of movement when it reaches the end of the rotating shaft 11. When the rotating block 31 moves to this point, due to the tangent design of the notch, the rotating block 31 can naturally switch from the trajectory of one spiral groove to the trajectory of another spiral groove to achieve continuous movement.

[0065] The fan-shaped arc surface 311 on the rotating block 31 is formed with a guide opening 3111 that matches the connection conversion slot 112. The two sides of the guide opening 3111 are also in the shape of circular arc tangents, and its curvature and size are adapted to the tangent part of the connection conversion slot 112. Such a design enables the guide opening 3111 to fit tightly on the connection conversion slot 112, ensuring accuracy and stability during the conversion process. The main function of the guide opening 3111 is to guide the rotating block 31 to smoothly enter the connection conversion slot 112 when it reaches the end of the rotating shaft 11, and to change direction along the tangent surface of the spiral groove. Its circular arc tangent design can reduce collision and friction during the conversion process, so that the rotating block 31 can transition from the spiral groove at one end to the spiral groove at the other end in a relatively smooth manner.

[0066] In summary, the design of the connection conversion slot 112 and the guide opening 3111 ensures the movement continuity of the shower seat assembly 3 during the entire lifting process. When the rotating block 31 slides up and down on the rotating shaft 11, it can change direction without any hindrance whether it reaches the upper end or the lower end, so that the lifting action of the shower seat can be continued without the movement interruption caused by the inability to change direction, providing a smoother operation experience for the user.

[0067] At the same time, due to the tangential design of the connection conversion notch 112 and the guide opening 3111, the rotating block 31 can be connected in a relatively gentle manner during the conversion process, avoiding severe friction caused by sudden collision or jamming between components. This can extend the service life of the rotating block 31 and the rotating shaft 11, and reduce component damage and maintenance costs caused by wear.

[0068] Furthermore, in some specific embodiments, a first fixing seat 5 and a first housing 6 are installed at one end of the slide bar assembly 1; wherein, the first fixing seat 5 includes a first square arc column portion 50 and a first special-shaped column portion 51, and the first special-shaped column portion 51 is inserted into a fixed square hole installed at one end of the slide bar body 10 to achieve the connection between the first fixing seat 5 and the slide bar body 10, complete the preliminary positioning and limiting, and ensure that the two are relatively fixed in the vertical direction to avoid displacement. At the same time, second threaded holes can be respectively opened on both sides of the first fixing seat 5, and correspondingly, U-shaped threaded holes are respectively formed on both sides of the U-shaped arc hole 101 on the slide bar body 10, and the second screw passes through the second threaded hole on the first fixing seat 5 and is screwed to the U-shaped threaded hole of the slide bar body 10, so that the first fixing seat 5 and the slide bar body 10 are firmly locked, further ensuring the stability of the overall structure.

[0069] The first square arc column portion 50 is inserted into and installed in the square arc hole of the first housing 6 to achieve the connection between the first housing 6 and the first fixing seat 5 .

[0070] More specifically, the other end of the slide bar assembly 1 is installed with a second fixing seat 7 and a second housing 8; wherein, the second fixing seat 7 includes a second square arc column portion 70 and a second special-shaped column portion 71, and the second special-shaped column portion 71 is inserted into and installed in the fixing square hole at the other end of the slide bar body 10, so as to realize the connection between the second fixing seat 7 and the slide bar body 10, complete the preliminary positioning and limiting, and ensure that the two are relatively fixed in the vertical direction to avoid displacement. At the same time, third threaded holes can be respectively opened on both sides of the second fixing seat 7, and correspondingly, U-shaped threaded holes are respectively formed on both sides of the U-shaped arc hole 101 on the slide bar body 10, and the third screw passes through the third threaded hole on the second fixing seat 7 and is screwed to the U-shaped threaded hole of the slide bar body 10, so that the second fixing seat 7 and the slide bar body 10 are firmly locked, further ensuring the stability of the overall structure.

[0071] The second special-shaped column 71 has a rotation center hole 711, and the center shaft 113 at one end of the rotating shaft 11 is inserted and installed in the rotation center hole 711, and an arc-shaped protrusion 114 is provided at the end of the rotating shaft 11, and the arc-shaped protrusion 114 abuts against the working surface of the second special-shaped column 71; the rotation center hole 711 of the second special-shaped column 71 and the center shaft 113 at one end of the rotating shaft 11 are precisely matched, providing a stable rotation axis for the rotating shaft 11, so that it can flexibly rotate around the center, ensuring the accuracy and efficiency of power transmission. At the same time, the arc-shaped protrusion 114 at the end of the rotating shaft 11 abuts against the working surface of the second special-shaped column 71, that is, the tangent design effectively reduces the friction resistance when the rotating shaft 11 rotates, making the rotation process smoother and more stable, reducing energy loss and noise generation, and improving user experience.

[0072] In addition, the second square arc column 70 is inserted into the square arc hole of the second housing 8 to achieve the connection between the second housing 8 and the second fixing seat 7 .

[0073] Furthermore, in a specific embodiment, the driving assembly 2 includes a reduction motor 20 and a power source 21 .

[0074] The first special-shaped column portion 51 of the first fixed seat 5 has a motor accommodating cavity, in which the reduction motor 20 is installed, and the output end of the reduction motor 20 is transmission-connected with the other end of the rotating shaft 11; the first square arc column portion 50 of the first fixed seat 5 has a power supply accommodating cavity, in which the power supply 21 is installed, and the power supply 21 is electrically connected with the reduction motor 20 to provide power for the reduction motor 20. It should be noted that the specific transmission mode between the reduction motor 20 and the rotating shaft 11 is not limited in the present invention, and can be designed and selected by those skilled in the art according to actual conditions. As in the present embodiment, the output end of the reduction motor 20 is a D-shaped shaft, and a D-shaped hole is provided on the rotating shaft 11. The D-shaped shaft is assembled into the D-shaped hole to realize the transmission connection between the reduction motor 20 and the rotating shaft 11, effectively avoiding the relative sliding during the transmission process, and ensuring that the rotational power output by the reduction motor 20 can be accurately transmitted to the rotating shaft 11, so that the rotating shaft 11 rotates at a predetermined speed and direction, thereby accurately controlling the lifting action of the shower seat assembly 3.

[0075] More specifically, a first upper cover 52 is mounted on the first fixing seat 5, and a power limiting column 521 for limiting the power supply 21 and a motor limiting column 522 for limiting the reduction motor 20 are provided in the first upper cover 52. Due to the presence of the power limiting column 521 and the motor limiting column 522, the power supply 21 and the reduction motor 20 will not move relative to each other when sliding up and down on the shower slide assembly 3, thereby ensuring the stability of the entire drive assembly. This is crucial for the transmission connection between the reduction motor 20 and the rotating shaft 11. Stable transmission can reduce energy loss and mechanical wear, and improve transmission efficiency and service life.

[0076] It should be noted that the present invention does not limit the specific buckle connection method between the first fixing seat 5 and the first upper cover 52, as long as the buckle connection between the two is achieved. For example, in this embodiment, three buckle slots evenly distributed in the circumferential direction are provided on the first upper cover 52. Correspondingly, three connecting columns are formed on the first upper cover 52, and a convex structure is formed on the connecting column. The buckle connection between the two is achieved through the cooperation of the convex structure and the buckle slot.

[0077] Similarly, a second upper cover can be mounted on the second fixing seat 7 to prevent dust, etc. The second upper cover can be designed with reference to the structure of the first upper cover 52, which will not be described in detail here.

[0078] Furthermore, in some specific embodiments, the switch assembly 4 includes an upper switch button 40 for driving the shower seat assembly 3 to move upward, and a lower switch button 41 for driving the shower seat assembly 3 to move downward. Pressing the corresponding button can realize up and down lifting, and releasing the button can stop. Specifically, the switch assembly 4 is provided with two plugs, one plug is connected to the reduction motor 20, and the other plug is connected to the power supply 21.

[0079] When the user needs to raise the height of the shower seat assembly 3, he will press the upper switch button 40 of the switch assembly 4. First, after the upper switch button 40 is pressed, the circuit connection mechanism inside it is triggered, so that a path is formed between the power supply 21 and the button, and the power supply 21 starts to supply power. Then, through the pre-connected data line, the electrical signal emitted by the power supply 21 is accurately transmitted to the reduction motor 20. After receiving the signal, the reduction motor 20 starts to operate, and with the tight and stable fit between the D-shaped shaft at its output end and the D-shaped hole on the rotating shaft 11, the rotational power of the reduction motor 20 is efficiently transmitted to the rotating shaft 11, driving the rotating shaft 11 to start 360-degree rotation.

[0080] Since the rotating shaft 11 is provided with a bidirectional spiral groove 111, and the rotating block 31 in the shower seat assembly 3 cooperates with the bidirectional spiral groove 111 through its fan-shaped arc surface 311, the rotating block 31 will slide upward along the track of the spiral groove as the rotating shaft 11 rotates. During the sliding process, the shower seat body 30 is connected to the rotating block 31 and sleeved on the slide bar assembly 1, and will rise synchronously along the slide bar assembly 1 as the rotating block 31 moves upward, thereby achieving the rising adjustment of the height of the shower seat assembly 3.

[0081] When the rotating block 31 slides to the uppermost end of the rotating shaft 11, thanks to the unique design of the guide opening 3111 of the rotating block 31 and the connection conversion notch 112 of the rotating shaft 11, the circular arc tangent feature of the two enables the rotating block 31 to smoothly connect and convert into another spiral groove of the rotating shaft 11, and then continue to slide downward along the trajectory of the spiral groove. When the rotating block 31 slides to the lowermost end of the rotating shaft, the rotating block 31 smoothly connects and converts into another spiral groove of the rotating shaft 11, and continues to slide upward until the user releases the upper switch button 40, the reduction motor 20 stops running, and the shower seat assembly 3 stays at the currently reached height position.

[0082] When the user needs to lower the height of the shower seat assembly 3, he will press the lower switch button 41 of the switch assembly 4. The working principle thereof can be referred to the upper switch button 40 mentioned above, which will not be described in detail here.

[0083] The present invention further provides a shower based on the above shower seat lifting device, which is characterized by comprising the above shower seat lifting device and having all the advantages of the above shower seat lifting device, which will not be described in detail here.

[0084] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in the field after reading this specification are all within the scope of protection of the present invention.
