Description

Technical Field

[0001] This invention relates to the field of inflatable equipment technology, specifically to an inflatable sauna. Background Technology

[0002] Sauna rooms, also known as sweat steaming rooms, include dry sauna rooms and wet sauna rooms. Wet sauna rooms use heated mineral stones and water to generate steam, while dry sauna rooms use far-infrared rays and negative ions to achieve the sauna effect. Sauna rooms have multiple benefits such as weight loss, detoxification, and rheumatism relief, and are very popular among consumers.

[0003] Existing saunas typically include large, fixed wooden saunas and portable small inflatable sauna tubs. Large wooden saunas are constructed from spliced ​​wooden planks, resulting in bulky packaging, high transportation costs, and time-consuming assembly. They are inconvenient to carry, increase tree consumption, and are detrimental to environmental protection. Furthermore, wooden saunas have poor resistance to decay and insects, requiring the application of waterproof and anti-corrosion coatings to the wood surface, further increasing costs. Small inflatable sauna tubs are mostly used at home or for travel. Their small size makes them easy to carry, but they usually only provide enough space for a single user at a time, failing to meet the needs of multiple users simultaneously. They also restrict user movement, confining them to the sauna tub and reducing the enjoyment and overall experience.

[0004] In addition, large wooden sauna rooms and small inflatable sauna barrels are all of a fixed size, which cannot be used in different application spaces, nor can the size of the sauna space be adjusted according to the number of users. Summary of the Invention

[0005] The purpose of this invention is to overcome the defects in the prior art and provide an inflatable sauna room. This inflatable sauna room can solve the problems of large wooden sauna rooms being bulky, inconvenient to carry, and costly. It can also solve the problem that small inflatable sauna tubs cannot meet the needs of multiple users using them at the same time. In addition, it can also solve the problem that both large wooden sauna rooms and small inflatable sauna tubs cannot be adjusted in size to suit different application spaces.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0007] An inflatable sauna includes:

[0008] An inflatable base with a rectangular annular cross-section, the inflatable base having two long side segments and two short side segments, the long side segments having at least two independent chambers along their length, and the short side segments being connected to adjacent chambers;

[0009] An inflatable frame with a gantry structure, the inflatable frame including at least two independent sub-units, the at least two sub-units being sequentially straddled on the two long side segments along the length direction and connected to the chamber in a one-to-one manner;

[0010] Two inflatable side baffles are respectively set at both ends of the inflatable frame along the length direction and are connected to the adjacent short side segment and the sub-unit to close the sauna space formed by the inflatable frame and the inflatable base;

[0011] An inflatable fixing frame, in the form of a gantry structure, is straddling above the two long side segments and located between adjacent sub-units, used to fix the relative positions of the two adjacent sub-units;

[0012] The inflation / deflation unit is used to inflate and deflate the inflation base, the inflation frame, the inflation side baffle, and the inflation fixing frame.

[0013] A heater is foldably disposed within the sauna space along the inner side of the inflatable frame;

[0014] Several unidirectional air inlets are respectively disposed between the inflatable fixing frame and the adjacent sub-unit and between the adjacent chambers, for limiting the inflatable frame and the inflatable base to inflate from both ends toward the middle respectively;

[0015] The subunit and the long side of the inflatable base are provided with at least one folding part of equal size along the length direction. The folding part is folded or extended under the action of the inflation / deflation unit so that the long side and the corresponding subunit are shortened or extended.

[0016] Furthermore, the sub-unit has the same layer structure as the inflatable side baffle, and the layer structure includes a covering layer, a heat-insulating and reflective strip film, a hot-melt film and a reinforcing strip arranged sequentially from the outside to the inside;

[0017] The covering layer has an air-filled cavity. The hot-melt film is disposed on the inner surface of the covering layer and surrounds the covering layer to form several receiving cavities. Several heat-insulating and reflective strip films are disposed one-to-one in the receiving cavities. The sides of several reinforcing strips are fixed to the inner surface of the hot-melt film and located between adjacent receiving cavities to divide the air-filled cavity into several sub-cavities with open ends.

[0018] Furthermore, the hot melt film is hot melt welded to the cover layer, and a welding line is formed at the weld between the hot melt film and the cover layer. The side of the reinforcing strip is connected to the welding line and pulls the welding line into the interior of the inflation cavity.

[0019] Furthermore, the heat-insulating reflective strip film is a non-woven fabric-based reflective film or an aluminum film.

[0020] Furthermore, the longitudinal section of the inflatable fixing frame is I-shaped, and the two sides of the inflatable fixing frame are formed with embedding grooves for cooperating with the adjacent sub-units. Some of the one-way air inlets are disposed between the embedding grooves and the sub-units.

[0021] Furthermore, a fixing structure is provided between the embedding slot and the sub-unit, the fixing structure being used to fix the relative position of the embedding slot and the sub-unit.

[0022] Furthermore, the fixing structure is Velcro.

[0023] Furthermore, the one-way air intake has a first working state that is open and a second working state that is closed;

[0024] When the one-way air intake is in the first working state, the pressure of the environment at the air intake end of the one-way air intake is less than a preset threshold.

[0025] When the one-way air intake is in the second working state, the pressure of the environment at the air intake end of the one-way air intake is greater than a preset threshold.

[0026] Furthermore, the one-way air inlet is a gas pressure safety valve.

[0027] Furthermore, the inflatable side baffle is provided with an opening, which is configured as an installation door.

[0028] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0029] 1. The inflatable sauna of this application can be inflated and deflated by an inflation and deflation unit, so that the sauna can be transported after being deflated and compressed, resulting in small transport volume, light weight, and low transport cost.

[0030] 2. The inflatable sauna room of this application forms a sauna space by setting up an inflatable frame with multiple sub-units, which works in conjunction with two inflatable side panels and an inflatable base, making it suitable for use by multiple people at the same time.

[0031] 3. The inflatable sauna of this application has at least one folding part of equal size along the length direction on the long side of the inflatable base and the sub-unit of the inflatable frame. The folding part is folded or extended under the action of the inflation and deflation unit, so that the long side and the corresponding sub-unit are shortened or extended. The size of the sauna space can be adjusted according to the size of the site space and the space usage requirements to suit different scene environments and has a wide range of applications.

[0032] 4. The inflatable sauna of this application is equipped with several one-way air inlets to restrict the inflation frame and the inflation base from being inflated from both ends toward the middle. This allows the cavities in the inflation base to be filled with gas in sequence before the next chamber is inflated. Similarly, the corresponding sub-units are filled with gas in sequence before the next sub-unit is inflated through the adjacent inflation fixing frame. This ensures inflation efficiency and stable air pressure in each sub-unit and chamber after inflation, thereby ensuring the structural stability of the inflatable sauna after inflation.

[0046] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0047] Please see Figures 1 to 3 An embodiment of the present invention provides an inflatable sauna room, which includes an inflatable base 1, an inflatable frame, two inflatable side panels 3, an inflatable fixing frame 4, an inflation / deflation unit (unlabeled), and several one-way air inlets 5. The inflation / deflation unit is used to inflate and deflate the inflatable base 1, the inflatable frame, the inflatable side panels 3, and the inflatable fixing frame 4.

[0048] In this embodiment, there is at least one inflation / deflation unit. Each inflation / deflation unit includes a matching inflation valve and deflation valve. Multiple inflation units are respectively arranged on the two short side sections 12 of the inflation base 1 and on the outer side walls of the two inflation side baffles 3. The inflation valve is adapted to be connected to an external inflation device (not shown) for inflation. The inflation device can be a blower, which is a conventional structure and will not be described in detail here.

[0049] The inflatable base 1 has a rectangular annular cross-section and includes two long side segments 11 and two short side segments 12. Each long side segment 11 has at least two independent chambers 111 along its length, and each short side segment 12 is connected to an adjacent chamber 111. The inflatable frame has a gantry structure and includes at least two independent sub-units 2. These sub-units 2 are sequentially mounted across the two long side segments 11 along their length and are connected to the chambers 111 in a one-to-one manner. Two inflatable side baffles 3 are respectively located at both ends of the inflatable frame along its length and are connected to the adjacent short side segments 12 and sub-units 2 to enclose the sauna space formed by the inflatable frame and the inflatable base 1. It should be noted that the length direction is as follows... Figure 1 As indicated by the middle arrow a.

[0050] To facilitate user access to the sauna space, the inflatable side panel 3 is provided with an opening 31, which is configured to install a door 32. The inflatable side panel 3 is sealed at the opening 31 by welding to form a welding strip 33, and a zipper 34 is provided on the welding strip 33 to connect with the edge of the door 32.

[0051] In this embodiment, the width of the welding strip 33 is set to no more than 5cm to enhance aesthetics. The door 32 is a door curtain, and a window 35 is provided on the door curtain. The door 32 can be specifically set as arched or rectangular, single or multiple leaves, and this application does not make specific limitations in this regard. In use, the opening 31 can be opened or closed by operating the zipper 34, which is simple to operate and convenient for folding and storage.

[0052] In order to facilitate the deflation and folding of the inflatable sauna, in this embodiment, at least one folding part 6 is provided on the long side segment 11 and the sub-unit 2 of the inflatable base 1 along the length direction. The folding part 6 is folded or extended under the action of the inflation and deflation unit so that the long side segment 11 and the corresponding sub-unit 2 are shortened or extended.

[0053] To improve insulation and ensure stable temperature within the sauna space, subunit 2 and inflatable side panel 3 have the same layer structure, which includes a covering layer 71, a heat-insulating and reflective strip film 72, a heat-melting film 73, and a reinforcing strip 74 arranged sequentially from the outside to the inside. It is worth noting that the door 32 also has the same layer structure as subunit 2 and inflatable side panel 3.

[0054] Specifically, the covering layer 71 has an inflation cavity (unlabeled). A hot-melt film 73 is disposed on the inner surface of the covering layer 71 and surrounds the covering layer 71 to form several receiving cavities (unlabeled). Several heat-insulating reflective strip films 72 are disposed one-to-one in the receiving cavities. Several reinforcing strips 74 are fixed to the inner surface of the hot-melt film 73 and located between adjacent receiving cavities to divide the inflation cavity into several sub-cavities (unlabeled) with openings at both ends. In this embodiment, the heat-insulating reflective strip film 72 is a non-woven fabric-based reflective film or an aluminum film.

[0055] The hot-melt film 73 is hot-melt welded to the cover layer 71, forming a weld line at the weld joint. The side of the reinforcing strip 74 is connected to the weld line, pulling the weld line towards the interior of the inflation cavity. When the inflation cavity is inflated, the portion of the cover layer 71 corresponding to the upper part of the cavity arches upwards, causing the middle portions of the heat-insulating reflective strip film 72 and the hot-melt film 73 to also arch outwards. The heat-insulating reflective strip film 72 is located on the inner arc side of the cover layer 71. Notably, the weld line on the sub-unit 2 forms a fold 6 thereon.

[0056] The heat-insulating reflective strip film 72 has a strip-shaped structure, and its edges are limited by the weld between the hot-melt film 73 and the covering layer 71. This results in a higher fault tolerance rate when the covering layer 71, the heat-insulating reflective strip film 72, and the hot-melt film 73 become misaligned, effectively reducing manufacturing difficulty. By setting the heat-insulating reflective strip film 72 to reflect heat radiation in the sauna space, a heat preservation effect is achieved in the sauna space.

[0057] The inflatable fixing frame 4 has a gantry structure 32. The inflatable fixing frame 4 spans above the two long side segments 11 and is located between adjacent sub-units 2, used to fix the relative positions of the two adjacent sub-units 2. Several unidirectional air inlets 5 are respectively arranged between the inflatable fixing frame 4 and the adjacent sub-units 2 and between adjacent chambers 111, used to restrict the inflatable frame and the inflatable base 1 from inflating from both ends toward the middle.

[0058] Specifically, the one-way air intake component 5 has a first open working state and a second closed working state. In the first working state, the pressure of the environment at the air intake end of the one-way air intake component 5 is less than a preset threshold; in the second working state, the pressure of the environment at the air intake end of the one-way air intake component 5 is greater than the preset threshold. In this embodiment, the one-way air intake component 5 is a gas pressure safety valve.

[0059] like Figure 4 As shown. To improve the tightness of the fit between the inflatable mounting bracket 4 and the adjacent sub-unit 2, in this embodiment, the longitudinal section of the inflatable mounting bracket 4 is I-shaped, and the two sides of the inflatable mounting bracket 4 have embedded grooves 41 for fitting with the adjacent sub-unit 2. Part of the one-way air inlet 5 is disposed between the embedded groove 41 and the sub-unit 2. In this embodiment, in order to adapt to the shape of the sub-unit 2, the embedded groove 41 is arc-shaped so as to fit against the inflated covering layer 71 of the corresponding sub-unit 2.

[0060] To ensure the stability of the sub-unit 2 after being combined with the embedding slot 41, a fixing structure 8 is provided between the embedding slot 41 and the sub-unit 2. The fixing structure 8 is used to fix the relative position of the embedding slot 41 and the sub-unit 2. In this embodiment, the fixing structure 8 is a Velcro fastener. It is a conventional structure and will not be described in detail here.

[0061] Please see Figure 5 The heater is foldably disposed within the sauna space along the inner side of the inflatable frame. In this embodiment, the heater includes multiple heating units 9 connected in sequence in a foldable manner. Each heating unit 9 includes an outer frame 91 and an inner frame 92 disposed opposite to each other, and a heating plate 93 sandwiched between the inner frame 92 and the outer frame 91. In this embodiment, the heating plate 93 is a graphene heating plate or a nano-carbon graphite heating plate.

[0062] Specifically, both the inner frame 92 and the outer frame 91 are hollow structures. The inner frame 92 and outer frame 91 have identical structures, consisting of an upper frame (unlabeled), a lower frame (unlabeled), a left frame (unlabeled), a right frame (unlabeled), and multiple support beams 94. The two ends of each support beam 94 are connected to the upper and lower frames, respectively. In this embodiment, the support beams 94 are specifically arranged in pairs at equal intervals. The heating plate 93 is sandwiched between the corresponding inner frame 92 and outer frame 91. Multiple heating units 9 are laterally folded together via a hinge device (not shown), a conventional structure. The angle between adjacent heating units 9 is adjusted using the hinge device to arrange the heaters into different shapes, thus adapting to the shape within the sauna space.

[0063] Due to the application of the above technical solution, the beneficial effects of this application compared with the prior art are as follows:

[0064] 1. The inflatable sauna of this application can be inflated and deflated by an inflation and deflation unit, so that the sauna can be transported after being deflated and compressed, resulting in small transport volume, light weight, and low transport cost.

[0065] 2. The inflatable sauna room of this application forms a sauna space by setting up an inflatable frame with multiple sub-units, which works in conjunction with two inflatable side panels and an inflatable base, making it suitable for use by multiple people at the same time.

[0066] 3. The inflatable sauna of this application has at least one folding part of equal size along the length direction on the long side of the inflatable base and the sub-unit of the inflatable frame. The folding part is folded or extended under the action of the inflation and deflation unit, so that the long side and the corresponding sub-unit are shortened or extended. The size of the sauna space can be adjusted according to the size of the site space and the space usage requirements to suit different scene environments and has a wide range of applications.

[0067] 4. The inflatable sauna of this application is equipped with several one-way air inlets to restrict the inflation frame and the inflation base from being inflated from both ends toward the middle. This allows the cavities in the inflation base to be filled with gas in sequence before the next chamber is inflated. Similarly, the corresponding sub-units are filled with gas in sequence before the next sub-unit is inflated through the adjacent inflation fixing frame. This ensures inflation efficiency and stable air pressure in each sub-unit and chamber after inflation, thereby ensuring the structural stability of the inflatable sauna after inflation.

[0068] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
