Description

Technical Field

[0001] The invention relates to the field of seat mechanical design, and in particular to a mechanical structure of a wet steam chair and a sauna room comprising the same. Background Art

[0002] Wet steaming is a form of sauna. It mainly expands pores to expel toxins through steam contact with the skin, thereby promoting blood circulation and improving metabolism. Wet steaming usually uses electricity to boil water and generate steam, which is then introduced into a closed wet steam room through pipes. The wet steam room is full of water vapor and has high humidity. The current wet steam room is manually controlled. Generally, there is a control switch outside the wet steam room. After the switch is triggered, the boiler is started to generate steam, and the steam is sent into the wet steam room at a certain interval. At present, the sanatorium hotel does not only have a single wet steam room treatment method, but also usually has sweat steaming, wet steaming, hot springs, fish therapy, water bath SPA and other projects. Customers choose according to their needs. Therefore, wet steaming may be idle for a certain period of time, resulting in energy waste. Considering that there is a large amount of water vapor in the wet steam sauna room and the water vapor has a high temperature, the use of infrared or electric control sensors may bring certain electrical hazards and equipment short circuit risks. Therefore, it is not recommended to use power supply equipment directly in the wet steam room. At the same time, the wet steam room is generally narrow, so as to confine the water vapor in a smaller area to prevent the water vapor from escaping and failing to achieve the therapeutic effect. Therefore, the wet steam room also has high requirements for the use of its space. The design of the sauna room wet steam chair should also follow the basic principles of human factors engineering, so that the wet steam chair can provide services to users effectively, safely, healthily and comfortably in the wet steam environment.

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and implementations. It is to be understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present invention. It is also necessary to explain that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] See attached Figure 1 The wet steam sauna room 1 has the characteristic of small space, so it is necessary to effectively utilize the space to accommodate more users. The present invention provides a sauna room 1, in which a wet steam chair 2 provided by the present invention is arranged in parallel. The chair has a control function and can work safely and accurately in a humid and warm environment for a long time.

[0030] Attached Figure 2-5The wet steam chair 2 of the present invention is shown in detail. The chair is mainly composed of a slide rail 21, a slider 22, a seat 23, a headrest 24, a first cylinder 28 and a control device 29. Specifically, the seat 23 is fixedly connected to the slider 22. Therefore, the seat 23 can move up and down along the slide rail 21 following the slider 22, thereby realizing the adjustment of the seat height. Due to individual differences among users, some users have a higher height, and the seat 23 needs to be at a higher distance to meet the comfortable riding requirements. Therefore, a chair that can move up and down can provide comfort for users of different heights. The part of the slider 22 that contacts the slide rail 21 only needs to provide a locking device, which is locked when the slider 22 slides to an appropriate position to achieve the effect of fixing the height of the chair seat 23. The locking device can quickly lock the slider 22 and the slide rail 21 by pressing the eccentric wheel. In order to prevent the slider 22 from moving downward all the time, a limit device is required to limit the maximum displacement of the seat 23 moving downward. Usually, the maximum displacement is 400mm from the ground. The position limit can be limited by the maximum stroke of the first cylinder 28. When the piston of the first cylinder 28 abuts the bottom of the cylinder body, the maximum downward stroke of the seat part 23 is limited. However, excessive use of the piston in contact with the cylinder body will reduce the service life of the first cylinder 28. At the same time, accurate selection of the cylinder and installation, so that the first cylinder 28 can limit the seat part 23 at a suitable position, will also cause trouble to the technicians. Therefore, the present invention adopts other limiting structures to achieve the lowest moving position limit of the seat part 23. The wet steam chair 2 also includes a slide rail cover plate 27, a strip groove is opened in the middle of the slide rail 21, the first cylinder 28 is arranged inside the strip groove, the slide rail cover plate 27 is fixedly connected to the slide rail 21 and blocks the strip groove, and the slide rail cover plate 27 limits the maximum downward displacement of the slider 22. Therefore, the slide rail cover plate 27 can prevent debris from contaminating the first cylinder 28 in the slide rail 21 and prevent users from directly contacting the cylinder. On the other hand, it also realizes the limitation of the maximum downward movement distance of the seat part 23.

[0031] In a preferred embodiment, the wet steam chair 2 further includes a fixed seat 25 and a seat return spring 26. One end of the fixed seat 25 is fixedly connected to the lower part of the slider 22, and the other end is rotatably connected to the seat portion 23. One end of the seat return spring 26 is connected to the upper part of the slider 22, and the other end is fixedly connected to the seat portion 23. The seat return spring 26 tends to rotate the seat portion 23 upward around the fixed seat 25. Since the space of the sauna room 1 is relatively narrow, it is necessary to accommodate more people in a smaller space and to improve the user's comfort as much as possible. When the wet steam chair 2 is not in use, the seat return spring 26 folds the chair, thereby providing more activity space and comfort for the users in the sauna room 1. It is worth noting that in order to avoid over-stretching the spring and ensure that the seat portion 23 can be fixed on a horizontal plane for users to sit, the rotation angle of the seat portion 23 needs to be limited. The seat portion 23 of the present invention includes a support frame 231, wherein the portion of the support frame 231 rotatably connected to the fixing seat 25 has a recessed limiting groove, and the portion of the fixing seat 25 rotatably connected to the support frame 231 has a raised limiting portion 251. When the seat portion 23 rotates to a horizontal plane, the wall surface of the limiting groove of the support frame 231 can abut against the raised limiting portion 251 of the fixing seat 25, thereby limiting further rotation of the seat portion 23.

[0032] In a preferred embodiment, the steam chair 2 has only one slide rail 21, a connecting portion extends out from the middle of the slide rail 21, the connecting portion is fixedly connected to the seat portion 23, and the upper end of the slide rail 21 is fixedly connected to the headrest 24. At this time, the slide rail 21 also serves as the backrest of the steam chair 2. However, due to the existence of the slide rail 21, a long strip groove is provided in the middle for the connecting portion to slide. However, since the movable structure is exposed in the sauna room 1, it may cause damage to the user's back skin. In another preferred embodiment, the steam chair 2 has two other slide rails 21, and the two slide rails 21 are arranged in parallel on both sides and are simultaneously connected to the two side edges of the seat portion 23, thereby providing stable support for the seat portion 23, and a backrest is added in the middle of the slide rail 21, reducing the possibility of the slide rail 21 causing damage to the back skin. It is worth noting that when the slide groove of the slide rail 21 faces the user's back, the possibility of the user's back skin being pinched still exists. The specification of the present invention is attached. Figure 4A seat design that can effectively prevent the user's skin from being hurt is demonstrated. The wet steam chair 2 also has two balanced slide rails 21, and the two ends of the headrest 24 are respectively connected to the two balanced guide rails 21. The side of the slide rail 21 away from the seat part 23 is provided with a slide groove, and the slider 22 is suitable for moving along the slide groove. The back plate 20 is fixedly connected to the side of the slide rail close to the seat part 23, so that the back plate 20 covers the two slide rails 21 and the gap in the middle of the slide rail 21, forming a completely flat backrest. Preventing the user's skin from being hurt. The fixed seat 25 is fixedly connected to the edge of the slide rail 21 at the edge of the slider 22 and the edge of the seat part 23.

[0033] The present invention realizes the control of the sauna room 1 by utilizing the movable function of the seat up and down adjustment while satisfying the requirement of being able to adjust up and down for a comfortable experience. The first cylinder 28 includes a first piston and a first cylinder body, and the slider 22 is fixedly connected to the first piston. At the same time, the control device 29 includes a second cylinder 291, a sensor block 292 and a reset device. The second cylinder 291 includes a second piston and a second cylinder body. The first cylinder body is connected to the second cylinder body pipeline. Therefore, during the user's use, the first piston of the first cylinder 28 is pressed downward, and the gas in the first cylinder 28 flows along the pipeline to the second cylinder body, so that the second piston of the second cylinder 291 can rise. The second piston is connected to the sensor block 292 to control the sensor block 292 to extend or retract to the outside of the control device 29. The wall of the sauna room 1 is provided with a groove at a position opposite to the sensor block 292, and a near-iron sensor is arranged in the groove. In the process of extending, the sensor block 292 is suitable for entering the groove, so that it is sensed by the near-iron sensor, and an instruction to start the steam delivery pipeline in the sauna room 1 to spray steam is sent. Since the near-iron sensor works on the principle that there is a magnetic body in the sensing area, the near-iron sensor can be protected outside the sauna room 1 by a waterproof material, thereby avoiding the danger of electricity consumption caused by the circuit being affected by the humid environment, and also improving the life of the electrical equipment. The reset device tends to push the second piston to move to the lowest position and make the first piston located at the highest position, so that after the user stands up from the seat portion 23, the first cylinder 28, the second cylinder 291 and the first seat portion 23 are reset. Under the condition that the second cylinder 291 meets the action of the push sensing block 292, the control device 29 should have a smaller height as much as possible to optimize the use of space. Therefore, in a preferred embodiment, the inner diameter of the second cylinder body is at least 4 times the inner diameter of the first cylinder body. And the large inner diameter of the second cylinder body can cooperate with the reset device to complete the reset process from fast to slow, which is convenient for the seat portion 23 to move downward.

[0034] See attached Figure 7 , 9, the reset device can select a gas spring or a mechanical spring. In the preferred embodiment of the present invention, a cylinder reset spring 294 is used to achieve the above purpose. The control device 29 includes a control box housing 293 and a limit plate 296. A strip limit portion 2931 is provided inside the control box housing 293. The limit plate 296 is fixed to the top of the second piston. One end of the cylinder reset spring 294 is connected to the top of the control box housing 293, and the other end is connected to the top of the limit plate 296. The strip limit portion 2931 is suitable for contacting with the limit plate 296, and the limit portion 251 limits the maximum upward movement distance of the limit plate 296. Therefore, in the process of the user sitting down on the chair, the following process is actually undergone.

[0035] Rapid descent process: When the user starts to sit in the seat portion 23, the first piston moves downward. Since the diameter of the second cylinder is much larger than the diameter of the first cylinder, the second piston has a smaller moving distance relative to the first piston. And since the second piston moves upward, the gas pressure inside the first cylinder and the second cylinder changes less. Therefore, the first piston can have a faster downward movement speed.

[0036] Slow descent process: When the second piston pushes the limit plate 296 to abut against the strip limit portion 2931. The second cylinder 291 cannot move upward through the second piston to ensure the stability of the pressure in the cylinder. At this time, as the first piston moves downward, the gas pressure in the first cylinder and the second cylinder increases rapidly, and the seat part 23 shows a decelerated descent. Finally, the gas pressure in the cylinder is sufficient to support the weight of the user. The present application enables the chair to be opened quickly and stabilized slowly through the rapid descent and slow stabilization of the seat part 23 at the beginning, so as to achieve the effect of convenient use and comfortable riding.

[0037] Furthermore, the control device 29 also includes a turntable 295, a rocker 297, a vertical rod 298, a connecting rod 299 and a control box cover 290. The turntable 295 is connected to the top of the control box housing 293, the rocker 297 is in an "L" shape, and the middle part of the rocker 297 is rotatably connected to the turntable 295. One end of the connecting rod 299 is rotatably connected to the vertical rod 298, and the other end of the connecting rod 299 is rotatably connected to the end of the long arm of the rocker 297. The vertical rod 298 is suitable for being fixedly connected to the limit plate 296. See the attached Figure 8The control box cover 290 is provided with a slot suitable for the sliding of the sensor block 292, and a control slot 2921 is provided in the middle of the sensor block 292. The length of the control slot 2921 is greater than the width of the short arm of the rocker, so that the short arm of the rocker can extend into the control slot 2921 and slide along the inner wall of the control slot 2921, thereby preventing the control slot 2921 from jamming the short arm of the rocker, causing the rocker 297 to be unable to rotate. The sensor block 292 can extend or retract the slot as the rocker 297 rotates, so as to transmit an opening or closing signal to the near-rail sensor on the inner wall of the sauna room 1.

[0038] It is worth noting that the present invention uses the first cylinder 28, the second cylinder 291 and the return spring to realize the two processes of fast and slow descent, thereby improving the comfort of the seat. However, the above scheme still lacks control over the recovery of the seat part 23. In the process of seat retraction, a relatively fast rebound stage is also required to reduce the time required to reset the chair. At the same time, when reaching the final reset position, a slow and non-oscillating reset is required to reduce damage to the seat part 23 and the guide rail. The wet steam chair 2 of the present invention also includes a first damper and a second damper, one end of the first damper is connected to the upper part of the slider 22, and the other end of the first damper is fixedly connected to the seat part 23. The first damper forms a structure arranged in parallel with the seat return spring 26. In the process of the seat return spring 26 driving the seat part 23 to recover, due to the action of the first damper, the seat part 23 is slowly retracted, and the instability caused by the simple harmonic vibration of the spring can be avoided. One end of the second damper is connected to the limit plate 296, and the other end is fixedly connected to the top wall of the control box housing 293, so that the limit plate 296 can move relatively slowly. After adding the second damper, the seat portion 23 will have a better contraction process. Specifically, the seat portion 23 also undergoes two processes when it contracts to the idle state:

[0039] Fast recovery process: When the user stands up from the seat portion 23, the seat portion 23 will be affected by the restoring force generated by the expansion of the high-pressure gas in the cylinder (including the first cylinder 28 and the second cylinder 291) and the restoring force provided by the cylinder return spring 294. It can be foreseen that the restoring force generated by the expansion of the high-pressure gas in the cylinder will dominate the recovery process, causing the seat portion 23 to rise faster.

[0040] Slow retraction process: When the high pressure gas in the cylinder is released, due to the action of the second damper, the cylinder return spring 294 fails to return the limit plate 296 to the initial position. The cylinder return spring 294 continuously pushes the limit plate 296, so that the seat 23 rises slowly. At the same time, due to the presence of the second damper, the elastic potential energy of the cylinder return spring 294 can be converted into the potential energy of the seat 23 rising on the one hand, and dissipated in the second damper on the other hand, thereby avoiding the seat 23 from generating simple harmonic vibration along the slide rail 21.

[0041] Preferably, the first damper and the second damper adopt small-hole dampers. The second damper includes a damping rod 310, a damping cylinder 320 and a cylinder cover 330. A through hole is provided in the middle of the cylinder cover, which is suitable for passing the damping rod 310, and the cylinder cover 330 is tightly connected with the damping rod 310 and the damping cylinder 320. A plurality of damping needles 340 are provided on the wall of the cylinder cover 330 facing the cavity of the damping cylinder 320. A piston 311 is provided at the lower part of the damping rod 310, and a damping hole corresponding to the damping needle 340 is provided on the piston 311, and the damping needle 340 passes through the damping hole 312; the diameter of the first end of the damping needle 340 connected to the cylinder cover 330 is larger than the second end of the damping needle 340. Preferably, the diameter of the end of the damping needle connected to the cylinder cover 330 is not less than 3 mm of the diameter of the damping hole. The damping needle 340 has a surface that changes continuously from the first end to the second end. The end of the damping rod 310 is connected to the top wall of the control box housing 293, and the bottom of the damping cylinder 320 is connected to the limit plate 296. Since the cross section of the damping needle 340 is variable, the flow area formed by the damping needle 340 and the damping hole 312 is continuously increased during the rapid descent of the seat, and the cylinder return spring 294 can shorten the energy storage relatively quickly and steadily; during the slow folding process, since the flow area formed by the damping needle 340 and the damping hole 312 is continuously reduced, the resistance of the oil passing through the damping hole 312 is increased, so that the seat part can be slowly folded, and the damping hole 312 consumes the energy in the cylinder return spring 294 in the form of heat, avoiding large-scale simple harmonic motion of the seat part.
