Description
Technical Field
[0001] The utility model relates to the technical field of light wave cabins, in particular to a light wave cabin headrest adjustment device. Background Art
[0002] The light wave cabin is a sauna lifestyle and a choice for modern healthy living. The main function of the light wave cabin is to promote blood circulation in the deep tissues of the human body, accelerate metabolism, and promote cell regeneration through the irradiation of infrared light waves. In the cabin, people can enjoy a comfortable temperature and soft light, which has a significant effect on relieving fatigue and improving sleep quality. At the same time, the light wave cabin can also effectively relieve muscle pain, eliminate inflammation, and has a certain effect on the auxiliary treatment of some chronic diseases.
[0003] The user lies in the cabin cover of the light wave cabin, with his head resting on the headrest of the light wave cabin. The light wave cabin headrest in the prior art is the same as an ordinary headrest, but the height of the headrest that each person adapts to is different. The prior art can only be adjusted by replacing headrests of different heights, and the adaptability is low. In order to prevent the heat in the light wave cabin from dissipating, a towel is usually placed around the neck to block the heat from dissipating. If the user feels that the position of the headrest is not suitable, he needs to extend his hand out of the cabin cover to adjust the headrest. Although the headrest is adjusted to the appropriate position, some of the internal heat will also dissipate as the hand is extended, and the treatment effect will also be reduced.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] See also Figure 1 This embodiment provides a light wave cabin headrest adjustment device, comprising a light wave cabin body 1 and a light wave cabin cover 2 located on the top of the light wave cabin body 1, a headrest 3 is fixedly arranged on the top of the light wave cabin body 1, the headrest 3 is located at one end of the light wave cabin cover 2, and a baffle 4 is respectively arranged on both sides of the headrest 3; a person lies in the light wave cabin body 1, covers the light wave cabin cover 2, and extends the head from the hole of the light wave cabin cover 2 (the hole is not numbered in the figure), and the head rests on the headrest 3, and the baffles 4 on both sides play a role in privacy protection. The direction pointed by the head and feet of the person lying in the light wave cabin is set as the length direction. The human body lies flat, and the directions of the two hands are on both sides, and in the width direction.
[0033] See also Figure 2-Figure 6 In this embodiment, the light wave cabin body 1 is provided with a recess (see Figure 2 and Figure 3, the pit is located at the bottom of the headrest 3, not numbered in the figure), and at least one electric push rod 32, a horizontal plate 311, and two electric guide rails 31 fixed on the horizontal plate 311 are arranged in the pit. The two electric guide rails 31 are respectively located on both sides of the horizontal plate 311, and the output end of the electric push rod 32 is fixedly connected to the bottom of the horizontal plate 311 (the electric push rod 32 is located at the center of the horizontal plate 311, not drawn in the figure), and the electric push rod 32 is used to drive the horizontal plate 311 and the two electric guide rails 31 to rise and fall.
[0034] In another embodiment (such as Figure 2-Figure 6 As shown in the figure, the output end of the electric push rod 32 is fixedly connected to the bottom of one of the electric guide rails 31. In order to achieve a balancing effect, the electric push rod 32 is located at the front / rear end of one of the electric guide rails 31. The rear / front end of the electric guide rail 31 and the front and rear ends of the other electric guide rail 31 are each provided with a telescopic rod. The telescopic rod and the horizontal plate 311 work together to ensure that the two electric guide rails 31 are raised and lowered synchronously and are always horizontal.
[0035] In this embodiment, a support assembly is slidably connected to the two electric guide rails 31. The support assembly includes two movable sliders 33 respectively slidably connected to the two electric guide rails 31. The movable slider 33 is provided with a first support rod 34, a second support rod 35, another second support rod 35, and another first support rod 34 in sequence along the direction away from the light wave cabin cover 2. The two first support rods 34 are fixed to the movable slider 33. The two second support rods 35 are hinged to the movable slider 33. A torsion spring is provided between the second support rod 35 and the movable slider 33. A first protrusion 341 is fixed to the first support rod 34, and a second protrusion 351 is fixed to the second support rod 35. The first protrusion 341 abuts against the bottom of the headrest 3, and the second protrusion 351 abuts against the bottom of the headrest 3. The first protrusion 341 and the second protrusion 351 extend in the width direction. The first protrusion 341 lifts up the headrest 3. When viewed from the side (such as Figure 3 As shown in the figure, the headrest 3 is in an M shape; the height of the second protrusion 351 is smaller than that of the first protrusion 341, the neck of the person is located on the headrest 3 on the upper side of the first protrusion 341 close to the light wave cabin cover 2, and the most protruding part of the back of the person's head is located between the two second protrusions 351. Since the two second support rods 35 are hinged to the movable slider 33, when the head of the person is against the position of the headrest 3 between the two second protrusions 351, the two second protrusions 351 will be pushed to move away from each other, so that the shape of the headrest 3 fits the head better; when the person leaves the headrest 3, the two second support rods 35 drive the two second protrusions 351 to return to their original positions.
[0036] During operation, the electric push rod 32 drives the two electric guide rails 31 to move up and down, so as to adjust the first protrusion 341 and the second protrusion 351 to move up and down. Since a circle of the headrest 3 is fixed on the light wave cabin body 1, the first protrusion 341 and the second protrusion 351 move up and down to change the height of the headrest 3 lifted by the first protrusion 341 and the second protrusion 351, thereby changing the height of the headrest 3; the movable slider 33 slides on the electric guide rail 31 to change the distance between the first protrusion 341 and the second protrusion 351 and the light wave cabin cover 2, so as to adjust the first protrusion 341 close to the light wave cabin cover 2 to be exactly located at the back of the neck, and the back of the head to be exactly located between the two second protrusions 351, so that the headrest 3 fits the head and neck of the person more closely.

[0038] See also Fig.10 In this embodiment, a horizontal slide groove 510 is provided on the housing 51, and the horizontal slide groove 510 is provided along the length direction of the light wave cabin body 1. A slider switch 52 is slidably connected in the horizontal slide groove 510, and the slider switch 52 slides along the length direction of the light wave cabin body 1. A first sliding contact piece 521 is provided at the bottom of the slider switch 52, and a first fixed contact piece 511 and a second fixed contact piece 512 are provided on the bottom wall of the horizontal slide groove 510 (the first fixed contact piece 511 is located at an end away from the headrest 3, and the second fixed contact piece 512 is located at an end close to the headrest 3). When a person lies on the light wave cabin body 1 and pushes the slider switch 52 downward relative to himself, at this time, the first sliding contact piece 521 contacts the first fixed contact piece 511, and the electric guide rail 31 drives the support assembly to move in a direction close to the light wave cabin cover 2; when the slider switch 52 is pushed upward, at this time, the first sliding contact piece 521 contacts the second fixed contact piece 512, and the electric guide rail 31 drives the support assembly to move in a direction away from the light wave cabin cover 2.
