Description

Technical Field

[0001] This utility model relates to the field of bathroom equipment technology, and in particular to an auxiliary shower device for the elderly. Background Technology

[0002] With the increasing trend of global population aging, the elderly face inconveniences in many aspects of daily life, with safety issues during bathing being particularly prominent. Due to the decline in physical function, the elderly experience reduced balance and slower reaction times while bathing, making them highly susceptible to accidents such as slipping and falling. For example, Chinese patent CN214208178U discloses a shower assistance device for the elderly. This device features a shower chair designed to facilitate elderly people sitting in it and includes a stretchable anti-slip mat to prevent slipping when getting up. However, it lacks a dynamic standing assistance mechanism and cannot safely assist the elderly in getting up. Chinese patent CN210472005U discloses another shower assistance device for the elderly, which includes a seat body with a pull-rod sitting cushioning mechanism on the seat and a shower head mechanism fixed above the backrest. This solves the problems of difficulty in sitting down and getting up while bathing and inconvenience in reaching the shower head. However, this patent mainly relies on the pull-rod sitting cushioning mechanism to help the elderly get up, providing only a single support function and lacking an alarm system for emergencies.

[0003] Most existing bathing aids on the market only offer simple support or assistance functions, which are insufficient to meet the diverse needs of the elderly during bathing, such as personalized bathing angle adjustment, convenient access to cleaning agents, safe and reliable assistance in getting up, and emergency alarms in case of emergencies. Therefore, developing a shower chair that integrates multiple assistance functions is of significant practical importance in improving the safety and comfort of bathing for the elderly. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary shower device for the elderly, which improves the safety and comfort of bathing for the elderly.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] An assistive shower for the elderly includes a seat body, which comprises a seat board and a backrest. The backrest is equipped with a shower arm module and an armrest module.

[0007] The shower arm module includes a shower arm mechanism, a shower arm rotating mechanism for driving the shower arm mechanism to rotate, and a shower arm lifting mechanism for driving the shower arm mechanism to rise and fall.

[0008] The handrail module includes a handrail mechanism and a handrail lifting mechanism that drives the handrail mechanism to rise and fall.

[0009] The base plate is equipped with an electric actuator linkage mechanism.

[0010] Preferably, the shower arm lifting mechanism includes two sets of first slide rail units symmetrically arranged on the left and right sides of the chair back. Each set of first slide rail units includes a first guide rail extending longitudinally along the chair back and a first guide rail slider slidably arranged on the first guide rail.

[0011] Preferably, the shower arm mechanism includes a first connecting plate and a shower arm unit disposed on the first connecting plate, wherein both ends of the first connecting plate are respectively connected to the first guide rail sliders in two sets of first slide rail units.

[0012] Preferably, the shower arm unit includes a shower arm shaft horizontally disposed on the first connecting plate, the shower arm shaft being disposed on the first connecting plate by a shower arm shaft fixing bracket, and shower arms being respectively connected to both ends of the shower arm shaft by pipe adapters.

[0013] Preferably, the first slide rail unit is driven by a first transmission unit, the first transmission unit includes a first rotary motor, the first rotary motor is connected to the chair back via a first motor mount, and the output end of the first rotary motor is connected to a synchronous belt mechanism.

[0014] Preferably, the timing belt mechanism includes a first flangeless timing pulley, a second flangeless timing pulley, and a timing belt. The timing belt is sleeved on the first and second flangeless timing pulleys. The first and second flangeless timing pulleys are arranged vertically along the longitudinal axis of the chair back. The first flangeless timing pulley is connected to the output end of a first rotary motor. The second flangeless timing pulley is mounted on the chair back via a tensioning wheel seat. A slider is provided on the timing belt, and the slider is connected to a first connecting plate.

[0015] Preferably, the second flangeless synchronous pulley is also connected to a synchronous pulley tensioning shaft and a deep groove ball bearing to ensure the stability and accuracy of the synchronous belt rotation and reduce friction.

[0016] In this invention, the first rotary motor is the power source. After the first rotary motor is powered on and started, it outputs rotational power to drive the synchronous belt mechanism to rotate.

[0017] In this invention, the synchronous belt mechanism is used to convert the rotational motion of the first rotary motor into the linear motion of the first connecting plate, thereby realizing the lifting and lowering of the shower arm mechanism. The slide rail structure ensures stable lifting and lowering, effectively adapting to the body characteristics of different users.

[0018] In this invention, the first guide rail is mounted on a slide rail and can slide freely on the slide rail. As the synchronous belt rotates, the slider on the synchronous belt is connected to the first connecting plate, and the first connecting plate is connected to the first guide rail slider, causing the first guide rail slider to slide up and down along the first guide rail. The up and down movement of the first guide rail slider will cause the shower arm to rise and fall vertically. The first guide rail provides precise guidance for the movement of the first guide rail slider, ensuring that the first guide rail slider can move stably along the vertical direction of the first guide rail.

[0019] Preferably, the shower arm rotating mechanism includes a second rotary motor, which is connected above the first connecting plate via a second motor mount. The output end of the second rotary motor is provided with a first bevel gear, and the shower arm shaft is provided with a second bevel gear that cooperates with the first bevel gear. The first bevel gear and the second bevel gear are in perpendicular contact.

[0020] Preferably, both the output shaft of the second rotary motor and the shower arm shaft are machined with grooves of matching shape and size. The first bevel gear and the second bevel gear are installed in the grooves and fit tightly together, so that the torque generated when the output shaft of the second rotary motor rotates can be stably transmitted to the shower arm shaft, avoiding relative slippage and ensuring the stability and accuracy of the shower arm rotation.

[0021] In this invention, driven by the second rotary motor, the first bevel gear rotates and drives the second bevel gear to rotate, which in turn drives the shower arm shaft to rotate, thereby realizing the rotation of the shower arm mechanism, increasing the sprayable area of ​​the shower arm mechanism, and meeting the user's needs for different spray angles during the bathing process.

[0022] In this invention, the second rotary motor serves as the power source and is securely fixed to the chair back with bolts. During installation, it is ensured that the motor position is accurate and that its output shaft is coaxial with the shower arm shaft to achieve efficient power transmission.

[0023] In this invention, the shower arm is a two-sided long rod shower arm, which can rotate around an axis and be raised and lowered vertically.

[0024] Preferably, the armrest lifting mechanism includes two sets of second slide rail units symmetrically arranged on both sides of the chair back. Each set of second slide rail units includes a second guide rail extending longitudinally along the chair back and a second guide rail slider slidably arranged on the second guide rail.

[0025] Preferably, the handrail mechanism includes a second connecting plate and handrails disposed on both sides of the second connecting plate. The two ends of the second connecting plate are respectively connected to the second guide rail sliders in two sets of second slide rail units, and a lifting platform is disposed in the middle of the second connecting plate.

[0026] Preferably, the second slide rail unit is driven by a second transmission unit, which includes a third rotary motor. The output end of the third rotary motor is connected to the end of a screw rod via a coupling. The screw rod is provided with a screw nut that forms a threaded engagement with it, and the screw nut is connected to the lifting platform.

[0027] Preferably, the lead screw nut is a ball screw nut.

[0028] Preferably, the chair back is provided with an upper support and a lower support, the upper support is located above the lifting platform, and the lower support is located below the lifting platform. The spiral screw passes vertically through the upper support and the lower support. A first bearing and a second bearing that can reduce the rotational friction of the spiral screw are respectively installed between the spiral screw and the through holes of the upper support and the lower support. The third rotary motor is set below the lower support through a third motor mount.

[0029] In this invention, the power output from the third rotary motor is transmitted to the screw, which rotates stably under the support of bearings at both ends. The first and second bearings reduce friction during screw rotation, ensuring smooth and precise rotation.

[0030] In this invention, the rotational motion of the screw and the screw nut can be converted into the linear motion of the screw nut through the cooperation of the screw and the screw nut.

[0031] In this invention, when the screw is rotated under the drive of the third rotary motor, the screw nut, being connected to the lifting platform, cannot rotate with the screw and can only move linearly along the axial direction of the screw. As the nut moves axially on the screw, a vertical thrust is generated. This thrust acts on the lifting platform, thereby causing the handrail fixed on the lifting platform to rise or fall.

[0032] In this invention, metal plates and connectors, including the upper and lower supports, the third rotary motor, etc., are used to fix the lead screw, motor, and other components. They are connected to each other by bolts or other fastening methods to form a stable frame structure, ensuring that the relative positions of each component remain unchanged during the lifting and lowering of the handrail, and guaranteeing the reliable operation of the entire lifting system. The second guide rail provides guidance for the movement of the lifting platform. The second guide rail is installed on the guide rail and can slide freely on it, allowing the handrail to move smoothly along the vertical direction during the lifting and lowering process, avoiding swaying or deviation.

[0033] Preferably, a cleaning agent module is provided below one side of the handrail in the handrail mechanism.

[0034] Preferably, the cleaning agent module includes a housing, an inductive switch installed on the outside of the housing, a transparent liquid storage bottle for storing the cleaning agent installed inside the housing, a flexible nozzle installed at the bottom of the transparent liquid storage bottle, a squeezing mechanism provided on one side of the flexible nozzle, the squeezing mechanism being connected to a micro motor, and the squeezing mechanism being able to squeeze the flexible nozzle and squeeze out the cleaning agent under the drive of the micro motor.

[0035] Preferably, the extrusion mechanism includes an eccentric driven wheel located at the bottom of the micro motor, a connecting rod mounted at the bottom of the driven wheel, an extrusion plate mounted at the bottom of the connecting rod, and the extrusion plate located on one side of the soft nozzle.

[0036] In this invention, when a hand is detected approaching, the sensor switch triggers the micro motor to start. The micro motor drives the driven wheel to rotate through gears. The driven wheel drives the extrusion plate to move left and right through a connecting rod, repeatedly squeezing the soft nozzle to squeeze out the cleaning agent. The cleaning agent flows out through the soft nozzle for the user to use.

[0037] Preferably, the seat plate includes a base and a seat plate body disposed on the base. The front end of the seat plate body is rotatably connected to the base via a rotating shaft assembly, and an electric push rod mechanism is provided at the center of the bottom of the seat plate body.

[0038] Preferably, a connector is horizontally mounted between the two support legs at the rear end of the base, the fixed end of the electric push rod mechanism is connected to the middle of the connector, and the actuating end of the electric push rod mechanism is connected to the center of the base plate body.

[0039] Preferably, the support leg is fixed to the ground.

[0040] In this invention, the seat body is lifted by an electric actuator linkage mechanism. The electric actuator linkage mechanism transmits motion and force by connecting multiple movable rods, enabling the seat body to rotate around an axis, thereby lifting the seat body and providing support for the elderly to get up.

[0041] In this invention, the first rotary motor, the second rotary motor, and the third rotary motor serve as the power source for each module. After the power is turned on, the motors start to run and output rotational power.

[0042] In this invention, a height-adjustable handrail mechanism and a liftable seat constitute an auxiliary standing module to help the elderly stand up. The handrail lifting mechanism of the auxiliary standing module adopts a screw lifting structure, and the seat lifting structure uses an electric push rod mechanism. During the elderly person's standing process, the handrail continuously rises and the seat continuously rises, providing support for the elderly person's body and buttocks respectively, thus providing coordinated support for the elderly person to stand up.

[0043] Preferably, it also includes an alarm control module, which includes an alarm system and a control system. The alarm system includes a timer for detecting shower time and an alarm for issuing alarm signals. The control system is connected to the handrail module, the shower arm module, and the alarm system.

[0044] Preferably, the alarm system further includes a response button.

[0045] In this invention, the control system is integrated into a push-button switch and is used to control the functions of the handrail module, shower arm module, and alarm system.

[0046] In this utility model, the alarm system has two alarm modes: when the system actively alarms, the timer is connected to the control system and sends a signal to the user in a 20-minute cycle, requesting feedback within 1 minute and 30 seconds. When the user cannot press the response button, the control system starts the alarm program and the alarm sounds. Alternatively, the user can actively press the response button to directly enter the alarm program. After the alarm program is started, the control system stops the shower, sends an emergency message to the guardian's mobile phone, and connects to the property management system to notify the property management personnel.

[0047] This utility model addresses the bathing challenges faced by the elderly, integrating multiple functional modules to provide comprehensive assistance to seniors with some self-care ability but limited mobility and physical strength. Each module operates on a simple and effective principle, with a reasonable and practical structural design and convenient control. Through the coordinated use of bathing, washing, assisted standing, and safety alarm functions, it enhances the safety and comfort of bathing for the elderly, meets their potential bathing needs, and fills a gap in the domestic market for related intelligent assisted bathing products.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] (1) This utility model provides an elderly auxiliary shower by integrating a shower arm module that can be raised and rotated, a handrail module that can be raised and rotated, and an electric push rod linkage mechanism on the seat body. This elderly auxiliary shower can greatly improve the safety and comfort of elderly people when bathing.

[0050] (2) This utility model provides an adjustable shower arm by designing a shower arm rotation mechanism and a shower arm lifting mechanism to drive the shower arm to rotate and lift. The adjustable shower arm can be flexibly adjusted according to the physical characteristics of the elderly to achieve comprehensive bathing coverage, allowing the elderly to feel comfortable and convenient during the bathing process.

[0051] (3) This utility model can drive the handrail mechanism to rise and fall by designing a handrail lifting mechanism. By setting an electric push rod linkage mechanism at the bottom of the seat, it can help the elderly stand up. During the elderly standing, the handrail continues to rise and the seat continues to rise, providing support for the elderly's body and buttocks respectively. The handrail lifting structure and the electric push rod linkage mechanism work together to provide more stable support when the elderly stand up, effectively reducing the risk of falling when the elderly stand up.

[0052] (4) This utility model also includes an automatic sensing and dispensing cleaning agent module. The design of this module avoids the inconvenience of elderly people bending over to pick up and put in the cleaning agent, and improves the overall bathing experience.

[0053] (5) This utility model also includes an alarm system that can respond promptly when the elderly encounter an emergency. Whether the system actively detects an abnormality or the user actively seeks help, it can quickly notify relevant personnel to ensure the personal safety of the elderly to the greatest extent.

[0054] (6) This utility model is easy to operate. The design of each module fully considers the usage habits and physical condition of the elderly. The intelligent control method makes the operation simple and easy to understand. Even the elderly who are not familiar with electronic devices can easily get started. Attached Figure Description

The shower arm rotating mechanism 32 is used to drive the shower arm mechanism 31 to rotate, while the shower arm lifting mechanism 33 is responsible for driving the shower arm mechanism 31 to achieve the lifting function.

[0080] Meanwhile, an armrest module 4 is also provided at the backrest 2, which includes an armrest mechanism 41 and an armrest lifting mechanism 42. The armrest lifting mechanism 42 can drive the armrest mechanism 41 to perform lifting and lowering actions.

[0081] In addition, an electric push rod linkage mechanism 5 is provided on the seat plate 1 to meet the various assistance needs of the elderly during the shower process and improve the safety and comfort of use.

[0082] Example 2

[0083] An assistive shower device for the elderly, such as Figure 2 , 4As shown, the shower arm module 3 consists of a shower arm mechanism 31, a shower arm rotation mechanism 32, and a shower arm lifting mechanism 33, based on embodiment 1.

[0084] In this embodiment, as Figure 6 As shown, the shower arm lifting mechanism 33 includes two sets of first slide rail units 331 symmetrically arranged on the left and right sides of the chair back 2. Each set of first slide rail units 331 includes a first guide rail 3311 extending longitudinally along the chair back 2 and a first guide rail slider 3312 slidably arranged on the first guide rail 3311.

[0085] In this embodiment, the shower arm mechanism 31 includes a first connecting plate 311 and a shower arm unit 312 disposed on the first connecting plate 311. Both ends of the first connecting plate 311 are respectively connected to the first guide rail sliders 3312 in two sets of first slide rail units 331. The shower arm unit 312 includes a shower arm shaft 3121 horizontally disposed on the first connecting plate 311. The shower arm shaft 3121 is disposed on the first connecting plate 311 through a shower arm shaft fixing bracket 3122.

[0086] In this embodiment, the first slide rail unit 331 is driven by the first transmission unit 332. The first transmission unit 332 includes a first rotary motor 3321. The first rotary motor 3321 is connected to the chair back 2 through the first motor base 3322. The output end of the first rotary motor 3321 is connected to a synchronous belt mechanism 3323.

[0087] In this embodiment, the timing belt mechanism 3323 includes a first flangeless timing belt pulley 33231, a second flangeless timing belt pulley 33232, and a timing belt 33233. The timing belt 33233 is sleeved on the first flangeless timing belt pulley 33231 and the second flangeless timing belt pulley 33232.

[0089] In actual operation, the shower arm module of this embodiment uses the first rotary motor 3321 and the second rotary motor 321 as power sources. On the one hand, after the first rotary motor 3321 is powered on, it outputs rotational power to drive the synchronous belt mechanism 3323 to rotate. The synchronous belt mechanism 3323 is used to convert the rotational motion of the first rotary motor 3321 into the linear motion of the first connecting plate 311, thereby realizing the lifting and lowering of the entire shower arm mechanism 31. The first slide rail unit 331 can further ensure that the shower arm mechanism 31 achieves stable vertical lifting and lowering. On the other hand, under the drive of the second rotary motor 321, the first bevel gear 323 rotates and drives the second bevel gear 324 to rotate. The second bevel gear 324 drives the shower arm shaft 3121 to rotate, thereby realizing the rotation of the entire shower arm mechanism 31.

[0090] The elderly-assisted shower provided in this embodiment provides an adjustable shower arm through the above structure, which can be flexibly adjusted according to the physical characteristics of the elderly to achieve comprehensive bathing coverage, allowing the elderly to feel comfortable and convenient during the bathing process.

[0091] Example 3

[0092] An assistive shower device for the elderly, such as Figure 3 , 5 As shown, the handrail module 4 includes a handrail mechanism 41 and a handrail lifting mechanism 42, based on embodiment 2.

[0093] In this embodiment, as Figure 8 As shown, the armrest lifting mechanism 42 includes two sets of second slide rail units 421 symmetrically arranged on both sides of the backrest 2. Each set of second slide rail units 421 includes a second guide rail 4211 extending longitudinally along the backrest 2 and a second guide rail slider 4212 slidably arranged on the second guide rail 4211.

[0094] In this embodiment, the handrail mechanism 41 includes a second connecting plate 411 and handrails 412 disposed on both sides of the second connecting plate 411. The two ends of the second connecting plate 411 are respectively connected to the second guide rail sliders 4212 in the two sets of second slide rail units 421. A lifting platform 423 is disposed in the middle of the second connecting plate 411. The second slide rail unit 421 is driven by a second transmission unit 422. The second transmission unit 422 includes a third rotary motor 4221. The output end of the third rotary motor 4221 is connected to the end of the screw 4223 through a coupling 4222. A screw nut 4224 is disposed on the screw 4223 to form a threaded engagement with it. The screw nut 4224 is connected to the lifting platform 423.

[0095] In this embodiment, the chair back 2 is provided with an upper support 21 and a lower support 22. The upper support 21 is located above the lifting platform 423, and the lower support 22 is located below the lifting platform 423.

[0096] In this embodiment, the lead screw nut 4224 is a ball screw nut.

[0097] In actual operation, the third rotary motor 4221 serves as the power source for the handrail module 4 of this embodiment. The power output of the third rotary motor 4221 is transmitted to the screw 4223, causing the screw 4223 to start rotating. With the cooperation of the screw 4223 and the screw nut 4224, the rotational motion can be converted into linear motion. Since the screw nut 4224 is connected to the lifting platform 423, it can move linearly along the axial direction of the screw 4223. As the screw nut 4224 moves axially on the screw 4223, a vertical thrust is generated. This thrust acts on the lifting platform 423, thereby driving the handrail 412 fixed on the lifting platform 423 to rise or fall.

[0098] Example 4

[0099] An assistive shower device for the elderly, based on embodiment 3, such as... Figure 9 As shown, the seat plate 1 includes a base 11 and a seat plate body 12 disposed on the base 11. The front end of the seat plate body 12 is rotatably connected to the base 11 through a rotating shaft assembly 13. An electric push rod mechanism 5 is provided at the center of the bottom of the seat plate body 12. A connecting member 15 is horizontally mounted between the two support legs 14 at the rear end of the base 11. The fixed end 51 of the electric push rod mechanism 5 is connected to the middle of the connecting member 15, and the actuating end 52 of the electric push rod mechanism 5 is connected to the center of the seat plate body 12.

[0100] In this embodiment, the seat plate body 12 is lifted by the electric push rod linkage mechanism 5. The electric push rod linkage mechanism 5 transmits motion and force by connecting multiple movable rods, so as to realize the seat plate body 12 rotates around the axis, thereby lifting the seat plate body and providing support for the elderly to get up.
