Description

Technical Field

[0001] This invention relates to the field of skin rinsing devices, specifically to a rinsing device for acne treatment. Background Technology

[0002] In acne treatment, the rinsing process is crucial for both treatment effectiveness and skin protection, requiring three core elements: even rinsing, stable water temperature, and ease of operation. However, current acne rinsing methods primarily rely on manual operation, which presents significant technical limitations. Poor uniformity of manual rinsing: When patients rinse with their hands or with a regular spray nozzle, it is difficult to accurately control the rinsing trajectory and intensity, which can easily lead to excessive local friction (damaging the skin barrier) or incomplete rinsing (residual medication / dirt causing irritation). The problem of uneven rinsing is more prominent, especially in acne areas that are difficult to reach, such as the back and neck.

[0003] Existing auxiliary devices are inadequate: some rinsing devices used for skin cleaning either lack adjustable automatic moving mechanisms (unable to cover multiple acne areas) or have no heat preservation structure (unable to stabilize water temperature), and most rely on electric drive, resulting in complex operation and high costs, making it difficult to meet the refined and convenient needs of acne treatment.

[0004] Therefore, in order to address the pain points of poor rinsing uniformity, easy water temperature fluctuation, and inconvenient operation in acne treatment, there is an urgent need to develop a special rinsing device that can achieve automatic and uniform rinsing, continuous heat preservation, and simple structure, so as to solve the defects of existing technology and improve the safety and effectiveness of acne rinsing. Summary of the Invention

[0005] The purpose of this invention is to provide an acne treatment rinsing device that solves the problem of poor rinsing uniformity in existing devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an acne treatment rinsing device, comprising a housing, a first mounting base connected to the housing, a first connecting rod hinged to the first mounting base, a second connecting rod hinged to the first connecting rod, a nozzle hinged to the end of the second connecting rod, a bracket fixedly connected to the side of the housing, a first guide wheel rotatably connected to the top of the bracket, a second guide wheel rotatably connected to the upper surface of the housing, a pull rope wound in an S-shape around the first and second guide wheels, a counterweight fixedly connected to one end of the pull rope, and the other end of the pull rope fixedly connected to the upper middle part of the second connecting rod. When the counterweight falls under gravity, it can pull the second connecting rod downwards, thereby reducing the angle between the first and second connecting rods, and thus enabling the nozzle to move and spray.

[0007] Preferably, a hinge seat is provided at the end where the first connecting rod and the second connecting rod are hinged, and a non-rotatable first pulley is installed on the hinge seat. A second mounting seat is rotatably connected to the end of the second connecting rod. The nozzle is fixedly connected to the rotating shaft of the second mounting seat, and a belt is drivingly connected between the second pulley and the first pulley, so that when the second connecting rod swings on the first connecting rod, the orientation of the nozzle remains unchanged.

[0008] Preferably, a slider is fixedly connected to the first pulley, and a straight sliding groove that cooperates with the slider is provided on the hinge seat. When the first pulley slides on the hinge seat, the belt is slack.

[0009] Preferably, the hinge seat is threaded with a first locking pin, and the middle of the first pulley is provided with an elongated hole that mates with the first locking pin, and the pin cap of the first locking pin can abut against the first pulley.

[0010] Preferably, the nozzle is connected to a pipe, which sequentially passes through the second mounting base, the second connecting rod, the first connecting rod, and the first mounting base and is connected to the housing.

[0011] Preferably, a mounting block is fixedly connected to the bracket, a screw is threadedly connected to the mounting block, a rotating seat is rotatably connected to the end of the screw, the rotating seat slides linearly on the bracket, a control wheel is rotatably connected to the rotating seat, the side wall of the control wheel can fit against the shaft of the first guide wheel, and when the screw is tightened, the pressure between the control wheel and the shaft of the first guide wheel increases, thereby increasing the rotational resistance of the first guide wheel.

[0012] Preferably, the bracket is equipped with a displacement sensor for detecting the movement of the counterweight, the housing is connected to a filling pipe, and a water pump is installed on the filling pipe. The water pump operates when the displacement sensor detects that the counterweight has moved down.

[0013] Preferably, a valve is installed on the pipeline, and the valve closes when the angle between the first connecting rod and the second connecting rod decreases.

[0014] Preferably, the valve stem of the valve passes through the first connecting rod and is equipped with a gear, and an arc-shaped rack is installed on the second connecting rod. When the second connecting rod approaches the first connecting rod, the arc-shaped rack meshes with the gear and drives the gear to rotate.

[0015] Preferably, a slide block is fixedly connected to the second connecting rod, the arc-shaped rack is slidably connected to the slide block, and a second locking pin is threaded onto the slide block. When the second locking pin is tightened, the arc-shaped rack can be locked to the slide block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention features an adjustable nozzle structure, allowing for flexible adjustment of the spray direction based on the specific acne area during treatment, thus improving treatment precision. Furthermore, the linkage design between the counterweight and guide wheel enables automated nozzle position adjustment, reducing the complexity of manual operation. Additionally, the pulley and belt transmission design ensures nozzle stability during oscillation, further enhancing treatment effectiveness. The linkage control between the displacement sensor and water pump allows the device to automatically start and stop based on the movement of the counterweight, achieving intelligent operation. The valve and gear rack design not only controls the flow of the rinsing fluid but also automatically closes the valve through a mechanical structure, enhancing the device's reliability and safety.

Detailed Implementation

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-7 This embodiment provides a technical solution: an acne treatment rinsing device, including a housing 100, a first mounting base 200 connected to the housing 100, a first connecting rod 210 hinged to the first mounting base 200, a second connecting rod 220 hinged to the first connecting rod 210, a nozzle 230 hinged to the end of the second connecting rod 220, a bracket 400 fixedly connected to the side of the housing 100, and a first guide wheel 410 rotatably connected to the top of the bracket 400. The upper surface is rotatably connected to a second guide wheel 420. A pull rope 440 is wound around the first guide wheel 410 and the second guide wheel 420 in an S-shape. One end of the pull rope 440 is fixedly connected to a counterweight 430, and the other end of the pull rope 440 is fixedly connected to the upper middle part of the second connecting rod 220. When the counterweight 430 falls under the force of gravity, it can pull the second connecting rod 220 downward, so that the angle between the first connecting rod 210 and the second connecting rod 220 is reduced, thereby allowing the nozzle 230 to move and spray.

[0021] The housing 100 is equipped with a heating wire or made of heat-insulating material to maintain its heat preservation function, thus keeping the water used for rinsing inside the housing 100 at its temperature. When rinsing acne areas, the housing 100 is placed vertically, with the first connecting rod 210 and the second connecting rod 220 at the top. The nozzle 230 is located at the end of the second connecting rod 220. The significant swing friction between the first connecting rod 210 and the first mounting base 200 prevents the first connecting rod 210 from easily swinging relative to the first mounting base 200. During rinsing, the second connecting rod 220 is manually pulled upwards to allow the nozzle to spray... When the head 230 is at the top of the area to be rinsed, the second link 220 is released. At this time, the counterweight 430 moves downward under gravity, and then the counterweight 430 pulls the second link 220 through the pull rope 440. Since the pull rope 440 reverses direction through the first guide wheel 410 and the second guide wheel 420, it can vertically pull the second link 220 downward, so that the nozzle 230 at the end of the second link 220 can move automatically at a uniform speed to rinse the acne area, ensuring the uniformity of rinsing and that the rinsing meets the requirements, without over-rinsing one area or under-rinsing other areas.

[0022] A hinge seat 211 is provided at one end of the first connecting rod 210 and the second connecting rod 220, and a non-rotatable first pulley 300 is installed on the hinge seat 211. A second mounting seat 240 is rotatably connected to the end of the second connecting rod 220, and the nozzle 230 is fixedly connected to the second mounting seat 240. A second pulley 340 is fixedly connected to the rotating shaft of the second mounting seat 240, and a belt 330 is drivingly connected between the second pulley 340 and the first pulley 300. Thus, when the second connecting rod 220 swings on the first connecting rod 210, the orientation of the nozzle 230 remains unchanged.

[0023] The diameters of the first pulley 300 and the second pulley 340 are equal. The first pulley 300 is connected to the hinge seat 211 at the end of the first connecting rod 210 and cannot rotate relative to the hinge seat 211. Thus, when the second connecting rod 220 swings, the belt 330 and the first pulley 300 move relative to each other. At this time, the belt 330 can drive the second pulley 340 to rotate. The second pulley 340 then drives the second mounting seat 240 to rotate, so that the orientation of the nozzle 230 remains unchanged.

[0024] A slider 310 is fixedly connected to the first pulley 300, and a straight sliding groove that cooperates with the slider 310 is provided on the hinge seat 211. When the first pulley 300 slides on the hinge seat 211, the belt 330 is slack.

[0025] Depending on the area being rinsed, the initial height of the nozzle 230 needs to be changed. This requires changing the angle between the first connecting rod 210 and the first mounting base 200, thus necessitating a readjustment of the nozzle 230's angle. At this point, the first pulley 300 is controlled to slide, causing the belt 330 to loosen, allowing the second pulley 340 to swing freely, thereby changing the angle of the nozzle 230. When the spray direction of the nozzle 230 is adjusted to be perpendicular to the rinsing area, the first pulley 300 is controlled to slide, locking it and causing the belt 330 to tighten again. At this point, the nozzle 230 will not swing relative to the second connecting rod 220 when the second connecting rod 220 is not swinging.

[0026] The hinge seat 211 is threaded with a first locking pin 320, and the middle part of the first pulley 300 is provided with an elongated hole that mates with the first locking pin 320. The pin cap of the first locking pin 320 can abut against the first pulley 300.

[0027] The first locking pin 320 is threaded onto the hinge seat 211. By rotating the first locking pin 320, the pin cap of the first locking pin 320 can abut against or move away from the first pulley 300, thereby enabling the first pulley 300 to be locked or unlocked to the hinge seat 211, and enabling the belt 330 to be tightened or loosened.

[0028] The nozzle 230 is connected to a pipe 250, which passes through the second mounting base 240, the second connecting rod 220, the first connecting rod 210 and the first mounting base 200 in sequence and is connected to the housing 100.

[0029] The pipe 250 is used to conduct the liquid inside the housing 100 to the nozzle 230. The housing 100 is sealed. When the internal pressure of the housing 100 increases, the liquid inside the housing 100 can be sprayed out through the nozzle 230.

[0030] A mounting block 450 is fixedly connected to the bracket 400. A screw 460 is threadedly connected to the mounting block 450. A rotating seat 470 is rotatably connected to the end of the screw 460. The rotating seat 470 slides linearly on the bracket 400. A control wheel 480 is rotatably connected to the rotating seat 470. The side wall of the control wheel 480 can fit against the shaft of the first guide wheel 410. When the screw 460 is tightened, the pressure between the control wheel 480 and the shaft of the first guide wheel 410 increases, thereby increasing the rotational resistance of the first guide wheel 410.

[0031] The contact points between the pull rope 440 and the first guide wheel 410 and the second guide wheel 420 have sufficient friction (achieved through material selection or surface polishing), making it difficult for the pull rope 440 to slip relative to the first guide wheel 410 and the second guide wheel 420. As a result, when the rotation speed of the first guide wheel 410 decreases, the moving speed of the nozzle 230 decreases, thereby controlling the rinsing time. When the screw 460 is rotated, it can drive the rotary seat 470 to move linearly. At this time, the pressure between the control wheel 480 on the rotary seat 470 and the shaft of the first guide wheel 410 changes, which in turn increases the rotational resistance of the first guide wheel 410 and reduces the rotational speed of the first guide wheel 410.

[0032] A displacement sensor for detecting the movement of the counterweight 430 is installed on the bracket 400. A filling pipe 110 is connected to the housing 100, and a water pump 120 is installed on the filling pipe 110. The water pump 120 runs when the displacement sensor detects that the counterweight 430 has moved down.

[0033] The displacement sensor is used to detect the movement of the counterweight 430. When the counterweight 430 is detected to move downward, it indicates that the nozzle 230 is in a moving state. At this time, the water pump 120 runs, which pumps warm water into the tank 100, increasing the pressure inside the tank 100. As a result, the nozzle 230 sprays liquid to rinse the acne area.

[0034] A valve is installed on pipe 250. The valve closes when the angle between the first link 210 and the second link 220 decreases.

[0035] When the angle between the first link 210 and the second link 220 decreases, it indicates that the nozzle 230 has moved to the end of its stroke. At this point, the nozzle 230 will no longer move, thus closing the valve and ensuring that the same area will not be continuously rinsed after the nozzle 230 stops moving.

[0036] The valve stem passes through the first connecting rod 210 and is equipped with a gear 500. An arc-shaped rack 520 is installed on the second connecting rod 220. When the second connecting rod 220 approaches the first connecting rod 210, the arc-shaped rack 520 meshes with the gear 500 and drives the gear 500 to rotate.

[0037] When the second link 220 approaches the first link 210, the arc-shaped rack 520 on the second link 220 approaches and meshes with the gear 500, driving the gear 500 to rotate, thereby closing the valve.

[0038] A slide block 510 is fixedly connected to the second connecting rod 220, and an arc-shaped rack 520 is slidably connected to the slide block 510. A second locking pin 530 is threaded onto the slide block 510. When the second locking pin 530 is tightened, the arc-shaped rack 520 can be locked to the slide block 510.

[0039] By adjusting the sliding of the arc-shaped rack 520 relative to the slide block 510, the engagement timing of the arc-shaped rack 520 and the gear 500 changes when the second connecting rod 220 approaches the first connecting rod 210. This controls the spray range of the nozzle 230. When the valve is fully closed, the gear 500 stops rotating, and the first connecting rod 210 stops swinging relative to the second connecting rod 220. As a result, the counterweight 430 stops moving, preventing the water pump 120 from running continuously and causing excessive pressure inside the housing 100.

[0040] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
