Technical Field

[0001] This invention relates to the field of cryotherapy chamber technology, and more specifically to a surround air duct for an ultra-low temperature cryotherapy chamber. Background Technology

[0002] Cryotherapy, as an effective physical therapy method, is widely used in scenarios such as sports injury recovery, postoperative swelling relief, and chronic pain management. Most existing cryotherapy devices employ a fixed-duct structure, which rapidly lowers local or overall body temperature by spraying ultra-low temperature gas (typically -120°C to -180°C) onto the body surface, thereby achieving anti-inflammatory, analgesic, and blood circulation-promoting effects.

[0003] The existing air duct structure of cryotherapy chambers has many shortcomings in actual use. First, because it is a fixed setting, it cannot be adapted to the user's height and body shape, resulting in a limited range of cold air coverage and affecting the treatment effect. Second, the uneven distribution of cold air can easily lead to local overcooling or temperature dead zones, which not only reduces the efficiency of cryotherapy but may also cause discomfort or even frostbite to the user. In addition, existing cryotherapy chamber equipment usually lacks the function of directional cooling of specific areas, making it difficult to meet the needs of personalized treatment.

[0004] To address these issues, a surround air duct for ultra-low temperature cryotherapy chambers, characterized by its rational structure, high level of intelligence, and strong adaptability, is provided to improve uniformity, safety, and user experience during the cryotherapy process. Summary of the Invention

[0005] The purpose of this invention is to provide a surround air duct for ultra-low temperature cryotherapy chambers, which solves the problem that the existing fixed cryotherapy chamber air duct structure cannot be adapted and adjusted according to the user's height and body shape, resulting in limited cold air coverage, uneven cold air distribution, and affecting the treatment effect.

[0006] The present invention achieves the above objectives through the following technical solutions: A surround air duct for an ultra-low temperature cryotherapy chamber includes a central main air duct fixed to the inner wall of the cryotherapy chamber, and multiple branch air ducts distributed around the central main air duct. The central main air duct is provided with multiple movable seats that correspond one-to-one with the branch air ducts and can move vertically to adjust the height of each branch air duct. The branch air ducts are rotatably mounted on the movable seats, and the movable seats are provided with drive mechanisms for driving the branch air ducts to rotate and open, so as to drive two corresponding branch air ducts to form an annular ring that surrounds the human body.

[0007] As a further optimization of the present invention, the front of the cryotherapy chamber is provided with a double-door type door; the branch air duct is designed as a semi-circular arc structure to extend to the door, forming a continuous surrounding structure when the door is closed.

Positioning grooves are provided on both sides of the air outlet, and a driving member for opening the sealing member is provided in the positioning groove. The sealing member includes two second gears rotatably disposed in the central main air duct, and two double-door type sealing plates respectively fixed on the corresponding second gears. The driving member includes a first spring column, a pressing block fixedly disposed at the end of the first spring column, and a rack fixedly disposed on one side of the pressing block and meshing with the second gear.

[0012] As a further optimization of the present invention, positioning elements are provided on both sides of the air inlet; the positioning element includes a second spring post and a positioning block fixedly disposed at its end, the positioning block being shaped as a truncated quadrangular pyramid, and the positioning block matching the positioning groove.

[0013] As a further optimization of the present invention, each of the air outlets is provided with a mounting groove, and the mounting groove is provided with an adjusting member for adjusting the shape of the air outlet; the adjusting member includes a plate that is slidably disposed in the mounting groove, and a translation unit for driving the plate to rise and fall, and the plate is provided with a plurality of adjusting holes of different shapes.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1 To address the issue of uneven air distribution within existing cryotherapy chambers, resulting in insufficient cooling rates and compromised user experience and safety, please refer to [link to relevant documentation]. Figure 1-Figure 5 The present invention provides a surround air duct for an ultra-low temperature cryotherapy chamber, comprising a central main air duct 1 fixedly mounted on the inner wall of the cryotherapy chamber body 5, and multiple branch air ducts 2 distributed around the central main air duct 1. The central main air duct 1 is provided with multiple movable seats 3 that correspond one-to-one with the branch air ducts 2 and can move vertically to adjust the height of each branch air duct 2. The branch air ducts 2 are rotatably mounted on the movable seats 3, and the movable seats 3 are provided with a drive mechanism 4 for driving the branch air ducts 2 to rotate and open, so as to drive two corresponding branch air ducts 2 to form an annular ring that surrounds the human body. The front of the cryotherapy chamber body 5 is provided with a double-door type door 6. The branch air ducts 2 are designed with a semi-circular arc structure to extend to the door 6, forming a continuous surround structure when the door 6 is closed, so as to achieve all-round cooling of the target area.

[0021] The movable base 3 is equipped with rollers 301 and a first motor 302 for driving the rollers 301 to rotate. The side of the central main air duct 1 is provided with a sliding groove 106 that matches the rollers 301. Both the surface of the sliding groove 106 and the surface of the rollers 301 are provided with meshing teeth. When the first motor 302 is started, it drives the rollers 301 to rotate. The meshing between the rollers 301 and the sliding groove 106 causes them to move smoothly in the vertical direction of the sliding groove 106. The movable base 3 drives the branch air ducts 2 to rise or fall to a set height.

[0022] The drive mechanism 4 includes an arc-shaped gear ring 401 fixedly mounted on the top of the branch duct 2, a first gear 402 meshing with the arc-shaped gear ring 401, and a second motor 403 for driving the first gear 402 to rotate. The second motor 403 is fixedly mounted on the movable base 3. When the second motor 403 is started, it drives the first gear 402 to rotate, thereby driving the arc-shaped gear ring 401 and the branch duct 2 to rotate around the axis, realizing the opening and closing of the branch duct 2.

[0023] The back of the central main air duct 1 is provided with an air inlet pipe 101 for connecting to the evaporator, and the front of the duct is provided with multiple air outlets 102 evenly distributed. One end of the branch air duct 2 is provided with an air inlet 201 corresponding to the air outlet 102, so as to realize the air path connection with the central main air duct 1. The inner side of the branch air duct 2 is provided with multiple air outlets 202 evenly distributed along the circumference, so that the cold air is sprayed evenly in 360° when surrounding the human body.

[0024] When the cabin door 6 is opened, the branch air duct 2 can rotate to the retracted state, fitting against the inner wall of the cabin 5 to avoid obstructing the user's entry and exit. After the user enters the cabin, the system detects the user's height information (which can be detected by infrared recognition or manually input). The movable seat 3 rises or falls along the slide rail of the central main air duct 1, so that the branch air duct 2 is aligned with the body part to be treated (such as the shoulder, waist, etc.). The drive mechanism 4 is activated, causing the branch air ducts 2 on both sides to rotate and close, forming a complete ring-shaped enveloping structure. The cooling system is activated, and cold air (usually -120℃ to -180℃) is delivered to each branch air duct 2 through the central main air duct 1 and sprayed evenly onto the human body surface. After the cold therapy is completed, the branch air duct 2 rotates and opens again, the cabin door 6 opens, and the user leaves.

[0025] Example 2 Based on Example 1, in order to improve the connection accuracy between the central main air duct 1 and the branch air duct 2, and to adapt to the dynamic adjustment of the branch air duct 2, such as... Figures 5-6 As shown, the air outlet 102 is provided with a normally closed sealing member 103, which is used to block the air outlet 102 when the branch air duct 2 is not connected. Both sides of the air outlet 102 are provided with positioning grooves 104, and the positioning grooves 104 are provided with driving members 105 for opening the sealing member 103. The sealing member 103 includes two second gears 103b rotatably disposed in the central main air duct 1, and two double-door type sealing plates 103a respectively fixed on the corresponding second gears 103b. The driving member 105 includes a first spring column 105b, a pressing block 105a fixedly disposed at the end of the first spring column 105b, and a rack 105c fixedly disposed on one side of the pressing block 105a and meshing with the second gear 103b.

[0026] Positioning components 203 are provided on both sides of the air inlet 201. The positioning component 203 includes a second spring post 203b and a positioning block 203a fixed at its end. The positioning block 203a is shaped like a truncated quadrangular pyramid. The truncated quadrangular pyramid structure facilitates the smooth entry or exit of the positioning block 203a into or out of the positioning groove 104, improving assembly accuracy and stability. The positioning block 203a matches the positioning groove 104.

[0027] The air outlet 102 is sealed by the sealing plate 103a to prevent cold air leakage or foreign objects from entering. The branch air duct 2 rises or falls with the moving seat 3. When the branch air duct 2 moves to the position aligned with the central main air duct 1, the positioning block 203a is inserted into the positioning groove 104. During the insertion process, the positioning block 203a pushes the squeezing block 105a to compress the first spring column 105b. The squeezing block 105a drives the rack 105c to move. The rack 105c drives the second gear 103b to rotate. The second gear 103b drives the sealing plate 103a to open, and the air outlet 102 is connected to the air inlet 201. After the cold treatment is completed, the branch air duct 2 rotates and retracts. The positioning block 203a disengages from the positioning groove 104, the first spring column 105b resets, the driving component 105 retracts, the rack 105c drives the second gear 103b to reverse, and the sealing plate 103a closes again under the action of the second gear 103b, closing the air outlet 102.

[0028] The positioning block 203a and positioning groove 104 structure ensure precise connection of the air duct, improve the stability of air supply, and realize the automatic opening and closing of the air outlet 102 during the lifting or rotation of the branch air duct 2, reducing manual intervention and adapting to the dynamic adjustment of the branch air duct 2.

[0029] Example 3 Based on Examples 1 and 2, in order to improve the flexibility of cryotherapy and enhance local treatment capabilities, such as Figure 4 , Figure 7 As shown, each air outlet 202 is provided with a mounting groove 204, and an adjusting component 205 for adjusting the shape of the air outlet 202 is provided in the mounting groove 204. The adjusting component 205 includes a plate 205a slidably disposed in the mounting groove 204, and a translation unit 205c for driving the plate 205a to rise and fall. The plate 205a is provided with multiple adjusting holes 205b of different shapes. The shapes of the adjusting holes 205b include, but are not limited to, circular, elliptical, slit-shaped, inclined upward, inclined downward, diffused, or convergent structures. By switching the different shapes of the adjusting holes 205b, the direction, speed, and coverage of the airflow can be precisely controlled. For example, the diffused type is used to provide a gentle cooling experience, and the convergent type is used for high-intensity cooling.

[0030] When the adjustment component 205 is in the default position, a certain adjustment hole 205b on the plate 205a is aligned with the air outlet 202. Cold air flows out from the adjustment hole 205b, forming a preset airflow pattern. When adjustment is needed, the translation unit 205c is activated, which drives the plate 205a to slide in the mounting groove 204. The plate 205a switches to the target adjustment hole 205b position, making it coincide with the air outlet 202. The air outlet pattern changes accordingly, realizing dynamic adjustment of the airflow size, direction or distribution. The adjustment hole 205b is switched in real time as needed to adapt to the needs of different treatment stages.

[0031] Diverse airflow control is achieved through the adjustment holes 205b of different shapes, which greatly improves the flexibility of cryotherapy and enhances the local treatment capability, such as directional spraying, which is suitable for specific areas such as the shoulders, neck, and knees. Users can adjust the air volume and direction according to their own comfort, precisely control the air outlet area, and perform targeted and refined cryotherapy on local areas.

[0032] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
