[0054] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0055] For bathing of special groups with limited mobility, or bathing in the wild without traditional bathing equipment, bathing is usually carried out by setting up a shield where the bather lies. However, due to poor drainage in the lying position, dirty and sewage are easily accumulated, resulting in poor bathing comfort.

[0056] Based on this, the following embodiments are proposed.

[0057] Embodiment 1:

[0058] like Figure 1-4 As shown in FIG. 11 , this embodiment provides a bottom pad, which is used to connect the sheet-like shielding member 1 and to form a cabin 101 for bathing together with the shielding member 1, including:

[0059] A cushion body 2, wherein a bathing area 205 for a human body to lie down is formed on the upper surface of the cushion body 2 and extends from the front end of the cushion body 2 to the rear end of the cushion body 2, and the upper surface of the cushion body 2 is a slope surface in the bathing area 205, and the slope height of the slope surface gradually decreases from the front end of the cushion body to the rear end of the cushion body;

[0060] The rear end of the cushion body is provided with a drain port communicated with the bathing area.

[0061] In this embodiment, the front end is on the head side of the pad body, and the rear end is on the foot side of the pad body.

[0062] In this embodiment, the shielding member 1 that cooperates with the bottom pad to form the cabin body can be deformed and bent. Preferably, the shielding member 1 is designed to be sheet-shaped and elastic or flexible, for example, it can be a composite PVC resin sheet or a fabric that can be stretched or folded;

[0063] When the bather enters the cabin 101 to take a bath, he lies on the bathing area 205 of the cushion body 2. The cushion body 2 is overall trapezoidal in shape, so that the cabin 101 formed by it and the shielding member 1 has a larger head end space and a smaller foot end space, which fits the contour of the human body lying posture, and the upper surface of the cushion body 2 is a sloped surface in the bathing area 205, and the slope height gradually decreases from the front end of the cushion body to the rear end of the cushion body, so that when the human body lies on the cushion body 2, the front end is higher and the feet are lower, which increases the comfort of bathing, and when the bather is sprayed in the cabin 101, it is convenient for the spray water to flow down the sloped surface.

[0064] Preferably, a water recovery point is set at the drain port 6. More preferably, a first water storage tank 212 is provided at the rear end of the mat body. The first water storage tank 212 is connected to the drain port 6, so that the bathing water flowing down from the bathing area is collected in the first water storage tank 212, which is convenient for unified discharge or utilization from the drain port, effectively saving water resources and energy, especially suitable for outdoor conditions where water resources are scarce. The recovered water can be filtered and reused, which greatly alleviates the disadvantage of inconvenience in water collection. More preferably, a water suction motor device can be connected to the recovery point to accelerate water recovery.

[0065] Preferably, the angle between the slope surface of the cushion body 2 and the horizontal plane is 3° to 8°, which can not only keep the bather in a comfortable lying position with the head high and the feet low, but also enable the spray water to quickly gather into the first water storage tank 212 under the action of gravity, which is conducive to rapid drainage.

[0066] At the same time, the spray water is concentrated in the first water tank 212, close to the human feet. The first water tank 212 can also be used to achieve a foot soaking function. When a person lies in the bathing area to take a bath, the feet can be directly soaked in the first water tank, making full use of the spray water and its heat to provide a comfortable bathing environment for the bather.

[0067] In some embodiments, a concave cavity for a human body to lie down is formed on the upper surface of the cushion body, extending from the front end of the cushion body to the rear end of the cushion body. The concave cavity is located in the bathing area and is connected to the first water storage tank, so that the human body can lie comfortably in the concave cavity, which is conducive to preventing the human body from sliding down and keeping warm.

[0068] Preferably, the bottom surface of the concave cavity is a sloped surface, and the bottom of the concave cavity is connected to the first water storage tank 212.

[0069] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0070] The slope surface is formed with a plurality of drainage channels 209 gradually extending from the front end of the pad body to the rear end of the pad body;

[0071] The width of the slope surface gradually narrows from the front end of the pad body to the rear end of the pad body;

[0072] Ends of the plurality of drainage channels 209 are connected to the water storage tank 5 .

[0073] In this embodiment, the width of the sloped surface at the front end side is greater than the width at the rear end side, so that the bathing area 205 is trapezoidal in shape as a whole. The cushion body 2 is trapezoidal in shape as a whole, and the bathing area 205 is also trapezoidal in shape as a whole. When a human body lies on the cushion body 2, the space at the head end is larger and the space at the foot end is smaller, which fits the contour of the human body's lying posture and improves comfort. The end of the drainage channel 209 is connected to the water storage tank 5, further improving the drainage smoothness of the surface of the cushion body 2.

[0074] Optionally, in an implementation of this embodiment, as Figure 11-13 As shown,

[0075] The drainage channel 209 is a straight channel and / or the drainage channel 209 is a curved channel with different bending directions, such as a wavy channel.

[0076] Preferably, the bottom of the plurality of drainage channels 209 is formed with a stepped surface and / or a wavy surface, and the stepped surface and / or the wavy surface forms a third water storage tank 213 along the drainage direction thereof, and the angle between two adjacent surfaces of the stepped surface and / or the wavy surface forming the groove is preferably greater than 0 degrees and less than 90 degrees.

[0077] In this embodiment, Fig.12 As shown, the bottom of the plurality of drainage channels 209 is formed with stepped surfaces and / or wavy surfaces, and the stepped surfaces and / or wavy surfaces form a third water storage tank 213 whose bottom height continuously decreases along the drainage direction. Preferably, the angle between two adjacent surfaces of the stepped surfaces and / or wavy surfaces forming the third water storage tank 213 is preferably greater than 0 degrees and less than 90 degrees. This is beneficial for storing water on the one hand, and on the other hand, when the water flows from high to low on the slope surface and impacts the step layers of each step surface, it will be blocked by the step layers and the water will be dispersed, which is beneficial for hot water to release thermal energy, so that the thermal energy in the hot water can be fully utilized, which is beneficial for keeping the cabin 101 warm, and the third water storage tank 213 can continuously retain a certain amount of hot water, which is further beneficial for the insulation of the bottom and the insulation state in the cabin 101.

[0078] Of course, it can also be designed that the angle between the two adjacent surfaces of the step surface is greater than 90 degrees under the premise of ensuring a certain water storage function, such as Figure 3 As shown, it also has the advantage of the angle between two adjacent surfaces of the step surface and / or the wave surface being less than 90 degrees. The difference is that when the angle between two adjacent surfaces of the step surface is greater than 90 degrees, the water storage capacity of the third water storage tank 213 will be reduced, the impact of the water flow will be smaller, and the heating effect on the air will be smaller.

[0079] As another optional embodiment of the drainage channel, the drainage channel 209 has curved channels with different bending directions, such as a wavy channel. This design allows the water flow on the pad body 2 to have a longer flow path, which can fully release heat in the cabin 101 and can also form a certain resistance to the human body to prevent the human body from sliding down on the bottom pad.

[0080] Optionally, in an implementation of this embodiment,

[0081] The cushion body 2 has a first cavity formed inside, into which a fluid can flow and be discharged, and the flow rate can be adjusted. The fluid can be used to heat the cushion body, and the temperature and comfort of the cushion body can be adjusted by the flow rate. In this embodiment, hot water is introduced into the first cavity as an example. The introduction of hot water into the first air conditioner can make the overall temperature of the cushion body 2 more suitable for the bather to lie flat and take a bath.

[0082] Optionally, in an implementation of this embodiment,

[0083] A second cavity is also formed inside the cushion body 2, in which a steam generator is arranged. The cushion body 2 is provided with a water supply port connected to the water inlet of the steam generator and a steam nozzle or steam spout connected to the air supply port of the steam generator. The steam nozzle or steam spout is used to spray the steam generated by the steam generator toward a part of the human body.

[0084] In this embodiment, the water supply port provides liquid medicine to the steam generator as an example. Through the operation of the steam generator, the liquid medicine is prepared into liquid medicine steam, which is sprayed into the cabin 101 to form medicinal bath steam, thereby providing medicinal bath fumigation for bathers.

[0085] Optionally, in an implementation of this embodiment, as Fig.11 , 14 As shown,

[0086] A concave cavity extending from the front end of the cushion body to the rear end of the cushion body for a human body to lie on is formed on the upper surface of the cushion body, and the concave cavity is located in the bathing area.

[0087] In this embodiment, the concave cavity is provided to facilitate lying of a human body, and has a certain gathering effect on water on the cushion body, thereby increasing the comfort of the cushion body and making the cushion body have a better heat preservation effect.

[0088] Furthermore, the cushion body 2 is provided with an overflow groove 211 on the periphery of the bathing area 205, one end of the overflow groove 211 is connected to the first water storage tank 212, and the other end extends along the periphery of the bathing area 205 to the front end of the cushion body 2, and a second water storage tank 210 is provided at the bottom of the front end;

[0089] The bottom surface position of the second water storage tank 210 is lower than the bottom surface position of the first water storage tank 212, and is also lower than the connection position between the overflow tank 211 and the first water storage tank 212; the bottom surface height of the overflow tank 211 is inclined downward from the first water storage tank 212 to the second water storage tank 210, and the connection position between the overflow tank 211 and the first water storage tank 212 is higher than the bottom surface position of the first water storage tank 212.

[0090] Preferably, the overflow tank 211 is provided with a switch valve and a filter screen, and the switch valve can be opened or closed according to user needs.

[0091] In this embodiment, the connection position between the overflow tank 211 and the first water tank 212 is higher than the bottom position of the first water tank 212, so that the first water tank 212 plays a sedimentation role. When the bather is taking a spray bath in the cabin 101, the water flows along the slope surface to the first water tank 212 and continuously gathers in the first water tank 212. During the gathering process, most of the dirt in the water will settle to the bottom of the first water tank 212. When the water in the first water outlet tank 212 gathers to a higher water level, the bottom position of the second water tank 210 is lower than the connection position between the overflow tank 211 and the first water tank 212; the bottom height of the overflow tank 211 The first water tank 212 is inclined downward toward the second water tank 210, so that the water in the first water tank 212 can flow to the second water tank 210, and will flow along the overflow tank 211 into the second water tank 210. During the flow, the water is further filtered by the filter. The bottom surface of the second water tank 210 is lower than the bottom surface of the first water tank 212. After the water is gathered in the second water tank 210, it can be reused. For example, the circulating water can be reused for spraying again, or for rinsing the surface of the mat body 2 after bathing, or for washing hair, etc., which saves water and makes full use of the heat of hot water. At the same time, there is no need to set the water tank too large to affect the lying space.

[0092] Optionally, in an implementation of this embodiment, as Figure 3 As shown,

[0093] The cushion body 2 is an inflatable bottom cushion;

[0094] The cushion body 2 comprises a first surface layer and a second surface layer which are arranged opposite to each other in the thickness direction, a plurality of pressing strips 208 are formed between the first surface layer and the second surface layer, and a first air channel structure is formed between each two adjacent pressing strips 208 of the first surface layer and the second surface layer;

[0095] The drainage channel 209 is formed by the pressing areas, and each pressing area forms a corresponding drainage channel.

[0096] The inflatable base cushion is provided with a plurality of first air channel structures capable of controlling the inflation flow rate, and a pressing area is provided between each two adjacent sub-cushion bodies to separate the two adjacent first air channel structures, and the drainage channel 209 is formed in the pressing area, and each pressing area forms a corresponding drainage channel.

[0097] In this embodiment, the first air channel structure can be pressed in multiple pressing areas on the integral inflatable base pad, thereby forming multiple recessed slit grooves on the surface of the pad body 2 to naturally form multiple drainage channels 209 for water circulation, further facilitating the spray water to naturally form multiple water channels for discharge on the pad body 2.

[0098] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0099] The first airway structure is a trapezoidal column after being injected with gas; wherein the front end cross-sectional area of ​​the first airway structure is greater than the rear end cross-sectional area of ​​the first airway structure;

[0100] The overall shape of the cushion body 2 is a trapezoid with a high front end and a low rear end.

[0101] Preferably, the cushion body 2 has a first end 201 (i.e., the front end of the cushion body) and a second end 202 (i.e., the rear end of the cushion body) opposite to each other along its length direction, and a third end 203 (i.e., the left end of the cushion body) and a fourth end 204 (i.e., the right end of the cushion body) opposite to each other along its width direction, and the portion of the bottom cushion 2 located between the first end 201, the second end 202, the third end 203 and the fourth end 204 constitutes a bathing area 205;

[0102] Among them, the width of the first end 201 is greater than the width of the second end 202, and the height of the cushion body 2 gradually decreases from the first end 201 to the second end 202, the height of the third end 203 is greater than the height of the bathing area 205, and the height of the fourth end 204 is greater than the height of the bathing area 205.

[0103] In this embodiment, the bather enters the cabin 101 and lies on the cushion body 2 during bathing. The cushion body 2 has a first end 201 and a second end 202 opposite to each other in the length direction. The width of the first end 201 is greater than the width of the second end 202. The cushion body 2 has a third end 203 and a fourth end 204 opposite to each other in the width direction. The third end 203 and the fourth end 204 are relatively inclined, so that the cushion body 2 is a trapezoidal shape as a whole. Figure 3As shown, the cushion body 2 is in a trapezoidal shape as a whole, so that the cabin 101 formed by it and the shielding member 1 has a larger head end space and a smaller foot end space, which fits the contour of the human body lying posture, and the height of the cushion body 2 gradually decreases from the first end 201 to the second end 202, forming a slope structure, so that when the human body lies on the cushion body 2, the front end is higher and the feet are lower, which increases the comfort of bathing. By designing that the height of the third end 203 is greater than the height of the bathing area 205, and the height of the fourth end 204 is greater than the height of the bathing area 205, the bather can lie in the cabin 101. When receiving spraying, the spray water can be concentrated in the part between the third end 203 and the fourth end 204 and quickly discharged to the second end 202 along the slope structure, and discharged from the second end 202. The cushion body 2 is trapezoidal in shape as a whole, which further makes the upper body part of the bather have a wider space, and the spray water is not easy to accumulate. As the width of the cushion body 2 gradually decreases from the head end to the foot end, the spray water gradually accumulates and is uniformly discharged at the drainage end, that is, the second end. The structural design of the cushion body 2 can facilitate the uniform discharge or recovery of the spray water, but is not easy to accumulate the spray water, thereby further increasing the comfort of bathing.

[0104] Furthermore, during the use of the bottom mat, the sprayed water will gather at the second end 202, which is close to the feet of the bather, and will not affect the bathing comfort. The second end 202 can also be designed as a water recovery point, where water is recovered, which is suitable for outdoor conditions where water resources are scarce. The recovered water can be filtered and reused. A water suction motor device can be connected to the recovery point to accelerate water recovery.

[0105] The overall shape of the pad body 2 is not limited to a trapezoid, and may be a shape similar to a trapezoid or a shape similar to a rectangle.

[0106] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0107] The cushion body 2 includes a plurality of sub-cushion bodies 206 connected in parallel in sequence. Among the plurality of sub-cushion bodies 206 connected in parallel in sequence, the sub-cushion bodies 206 located on both sides of the width are respectively configured as the third end 203 and the fourth end 204, and the remaining sub-cushion bodies 206 are collectively configured as the bathing area 205.

[0108] In this embodiment, the sub-cushion bodies 206 located on both sides are higher than the other sub-cushion bodies 206, so that the heights of the third end 203 and the fourth end 204 are greater than the height of the bathing area 205, so that when the bather is sprayed in the cabin 101, the spray water can be concentrated in the part between the third end 203 and the fourth end 204 and quickly discharged to the second end 202 along the slope structure, and discharged from the second end 202, which can not only prevent water overflow on both sides of the bottom pad, but also facilitate the rapid gathering and discharge of water.

[0109] Preferably, the sub-cushion body 206 is cylindrical, and the cushion body 2 composed of a plurality of cylindrical sub-cushion bodies 206 connected in sequence is formed with a plurality of concave slit grooves on its surface in contact with the spray water, such as Figure 3 As shown, at the pressing strip 208 , a plurality of recessed slit grooves are formed, and a plurality of recessed slit grooves naturally form strip-shaped water supply and circulation channels on the surface of the pad body 2 , further facilitating the spray water to naturally form multiple water channels for discharge on the pad body 2 .

[0110] Optionally, in an implementation of this embodiment, as Figure 1 , 2 , 5, 6, and 8,

[0111] A lying pillow 3 is disposed at the first end 201 , and a through hole 4 is disposed at a position where the shielding member 1 and the lying pillow 3 are opposite to each other.

[0112] In this embodiment, when the bather lies on the cushion body 2 and takes a bath in the cabin 101, the front end of the cushion rests on the lying pillow 3. The setting of the lying pillow 3 further improves the bathing comfort of the bather. At the same time, the setting of the opening 4 can ensure smooth airflow at the bather's breathing area. The lying pillow 3 can be an inflatable lying pillow, a PVC one-piece lying pillow, and its surface is made of waterproof material.

[0113] Optionally, in an implementation of this embodiment, as Figure 1-4 As shown,

[0114] The cushion body 2 includes a first surface layer and a second surface layer arranged opposite to each other in the thickness direction, a plurality of pressing strips 208 are formed between the inner sides of the edges of the first surface layer and the inner sides of the edges of the second surface layer, and a first airway structure is provided between each two adjacent pressing strips 208 .

[0115] In this embodiment, in order to realize that the cushion body 2 has a slope, a recessed gap and other shapes, a trapezoidal material can be cut. When the cushion body 2 needs to be divided into n sub-cushion bodies 206, the material is divided into n parts, and the long base / n of the trapezoidal material is greater than the short base / n. The edges of the two pieces of trapezoidal material, namely the first surface layer and the second surface layer, are pressed together, and a plurality of pressing strips 208 are pressed on the inner side of the edges, so that an airway is formed between the upper and lower pieces of material (uninflated state). After gas is injected into the airway (inflated), the single airway becomes a trapezoidal cylinder with one end larger than the other, that is, the sub-cushion body 206 is a trapezoidal cylinder. When n airways are close together, the whole becomes a trapezoidal inflatable cushion, and at the same time, the effect of a slope with one side higher and a recessed gap with the other side lower is realized.

[0116] Alternative solution: In addition to constructing the pad body 2 as an inflatable cushion, other materials and processes can also be used, such as PVC material using a drawstring process or 3D designed PE co-extrusion material to directly produce a sloped mattress-type pad body 2. In addition, hard materials with a slope or non-inflatable cushions can also be used as the pad body 2.

[0117] Optionally, in an implementation of this embodiment, as Figure 1 , 2 , 5, 7, 10,

[0118] A closing portion 5 is formed on one side of the shielding member 1 close to the second end 202 , and the closing portion 5 is sealedly connected to the second end 202 .

[0119] In this embodiment, the end of the closing portion 5 connected to the second end 202 is an open structure, and the closing portion, the rear end of the base pad, and the rear end of the shielding member 1 together form a relatively closed space. When the bather lies on the base pad, the space corresponds to the position of the bather's feet. This design not only enhances the warmth of the foot position, but also facilitates centralized drainage. The spray water flow gathers in the first water storage tank 212 and is discharged together at the drain outlet 6.

[0120] Embodiment 2

[0121] like Figure 1-4 As shown, this embodiment provides a bag-like structure, including:

[0122] The shielding member 1 and the bottom pad in the first embodiment are connected together to form a cabin 101 for bathing.

[0123] In this embodiment, the shielding member 1 is preferably a thin layer of waterproof fabric, and the shielding member 1 is elastic, for example, it can be a composite PVC resin sheet, which is connected to the bottom pad and can be deformed and bent to form a cabin 101 to provide a bathing space for the bather. When the bather is in a state of inconvenience in movement, the bather completes the bathing process in the cabin 101 formed by the shielding member 1, and sprays the bather's body by spraying into the cabin 101. The front end of the bather extends through the opening on one side of the cabin to keep breathing smooth. The shielding member 1 can cover the upper and peripheral positions of the bather, so that the bather's privacy can be fully protected. In this way, during the entire bathing process, whether in the process of the bather's position conversion or in the process of the bather's spraying, the bather's privacy can be fully protected, which can reduce the bather's psychological burden to a large extent. A waterproof zipper can be set on the shielding member 1 to facilitate the opening and closing of the shielding member, so that the bather can enter the cabin 101; the shielding member 1 is used in conjunction with the overall trapezoidal cushion body 2, The cabin 101 has a larger head end space and a smaller foot end space, which fits the contour of the human body's lying posture. The slope structure of the cushion body 2 makes the front end of the human body higher and the feet lower when the human body lies on the cushion body 2, thereby increasing the comfort of bathing. When the bather is sprayed in the cabin 101, the spray water can be concentrated in the part between the third end 203 and the fourth end 204 and quickly discharged to the second end 202 along the slope structure and discharged from the second end 202. The cushion body 2 is trapezoidal as a whole, which further allows the bather's upper body to have a wider space, and the spray water is not easy to accumulate. As the width of the cushion body 2 gradually decreases from the head end to the foot end, the spray water gradually accumulates and is uniformly discharged at the drainage end, i.e., the second end, which is convenient for uniform discharge or recovery of the spray water and not easy to accumulate the spray water, thereby further increasing the comfort of bathing.

[0124] Optionally, in an implementation of this embodiment, as Figure 5-9 As shown,

[0125] The shielding member 1 is configured to be flexible, and a support member 7 is provided on the shielding member 1.

[0126] The support member 7 is attached to and supported on the outer surface of the shielding member 1. The support member 7 is designed to have a deformation capability. The support member 7 can have a supporting state or a non-supporting state through deformation.

[0127] When the support member 7 is in a supporting state, it supports the shielding member 1 ; when the support member 7 is in a non-supporting state, the supporting function is eliminated.

[0128] In this embodiment, the conversion of the supporting state and the non-supporting state of the support member 7 can be achieved by inflation and deflation, and can also be achieved by relying on the deformation characteristics of the material of the support member 7 itself. When the bag-like structure is needed, the support member 7 is inflated to make the support member 7 in a supporting state. At this time, the support member 7 has a certain supporting effect on the shielding member 1, so that the shielding member 1 is in a tensioned state and there is a gap between the shielding member 1 and the bather in the cabin 101, so that the shielding member 1 will not fall on the bather, thereby maintaining a gap between at least the upper part of the shielding member 1 and the bather's body, and the gap also provides a spraying space for the bather. When the bag-like structure is used, the support member 7 is deflated to make it in a non-supporting state and lose its tensioned state, which is convenient for the overall storage of the bag-like structure.

[0129] Optionally, in an implementation of this embodiment, as Figure 5-9 As shown,

[0130] The support member 7 includes a first support frame 701 , a second support frame 702 and a connecting column 703 . The connecting column 703 is connected between the first support frame 701 and the second support frame 702 . The first support frame 701 and the second support frame 702 are both surrounded and attached to and supported on the outer surface of the shielding member 1 .

[0131] Preferably, the first support frame 701 is constructed with symmetrical support columns, and a support beam is connected between the top ends of the two support columns. The structure of the second support frame 702 is the same as that of the first support frame 701, and the two ends of the connecting column 703 are respectively connected to the support beams on both sides.

[0132] In this embodiment, the bottom of the support column is supported on the bottom pad, and the connecting column 702 is connected to the top of the shielding member 1 so that the shielding member 1 and the bottom pad are both connected to the support member 7. The support member 7 is convenient for surrounding and supporting the outer surface of the shielding member 1, thereby providing better support for the shielding member.

[0133] Optionally, in an implementation of this embodiment, as Figure 5-9 As shown,

[0134] A first fixing member 8 is disposed on the outer surface of the shielding member 1, and a second fixing member 9 is disposed on the outer surface of the base pad. The first fixing member 8 is detachably connected to the connecting column 703, and the second fixing member 9 is detachably connected to the first supporting frame 701 and detachably connected to the second supporting frame 702.

[0135] In this embodiment, taking the example that the first fixing member 8 and the second fixing member 9 are both Velcro, the first fixing member 8 can be wrapped around the connecting column 703. By wrapping and bonding the first fixing member 8, it is firmly fixed on the connecting column 703, so that the support member 7 as a whole is firmly connected to the top of the shielding member 1, and this connection method is easy to disassemble.

[0136] A second fixing member 9 is provided at the bottom of the support column with a Velcro adhesive. By bonding the second fixing member 9 to the Velcro adhesive at the bottom of the support column, a firm connection is established between the support member 7 as a whole and the base pad, and this connection method is easy to disassemble.

[0137] Optionally, in an implementation of this embodiment, as Fig.10 As shown,

[0138] A waterway attachment layer is disposed on the shielding member 1 , a pipeline 10 is disposed in the waterway attachment layer, and the pipeline 10 has an inlet 1001 and an outlet, and the outlet is communicated with the cabin 101 .

[0139] In this embodiment, the pipeline 10 is arranged in the water channel attachment layer, which is convenient for assembly and does not occupy the bathing space. The inlet 1001 is located outside the shielding member 1, and the water outlets of the multiple outlets are directed into the cabin 101. Taking the pipeline 10 as a spray pipeline as an example, the water source pipe is connected to the inlet 1001, and the water flows in along the inlet 1001, and is discharged from the multiple outlets through the pipeline 10, and sprayed to the sides or the middle of the bather's body, so as to achieve a comprehensive spraying of the bather inside the cabin 101.

[0140] Specifically, the pipeline 10 includes a main pipe 1002 and a plurality of branch pipes, and the plurality of branch pipes and the inlet 1001 are both connected to the main pipe 1002;

[0141] The outlets are respectively arranged at intervals on a plurality of branch pipes, and the plurality of outlets face different positions of the bathing area 205 .

[0142] In this embodiment, the pipeline 10 includes a main pipe 1002, a first branch pipe 1003, a second branch pipe 1004 and a third branch pipe 1005. One end of the main pipe 1002 is connected to the first branch pipe 1003, the other end of the main pipe 1002 is connected to the second branch pipe 1004, the middle part of the main pipe 1002 is connected to the third branch pipe 1005, the inlet 1001 is connected to the main pipe 1002, and a plurality of outlets are provided, and the plurality of outlets are arranged at intervals on the first branch pipe 1003, the second branch pipe 1004 and the third branch pipe 1005.

[0143] In this embodiment, if the bather is lying on his back on the bottom mat, the spray direction is the sides of the bather's chest and the chest, and the length of the branch pipe is approximately the distance from the human clavicle to the calf. If the bather is lying prone on the bottom mat, the spray direction is the sides of the bather's back and the middle position. The water source pipe is connected to the inlet 1001, and the water flows along the inlet 1001, through the main pipe 1002, through the first branch pipe 1003, the second branch pipe 1004 and the third branch pipe 1005, and finally discharged from multiple outlets, spraying to the sides and the middle of the bather's body, so as to spray the bather on the inside of the cabin 101. If the bather is lying on his back on the bottom mat, the spray direction is the sides of the bather's chest and the middle position. If the bather is lying prone on the bottom mat, the spray direction is the sides of the bather's back and the middle position. This design of the spray pipe 10 allows the spray water to relatively comprehensively cover the bather, and the spray direction is gentle, increasing bathing comfort. The pipe 10 can be connected to fluids other than water sources, such as medicine sources, so that the bag-like structure can provide bathers with services such as medicinal bath fumigation.

[0144] In order to achieve a more comfortable shower experience, this embodiment finds an optimal balance between the water pressure of the water pump, the number of outlets and the outlet aperture. When the water pressure of the water pump and the number of outlets are fixed, the aperture size of the outlet will directly affect the feeling of water pressure. When the aperture is small, the water pressure will be greater. If the aperture is too large, the water pressure will decrease. Preferably, 40 to 50 outlets are set at a water pump water pressure of 0.5Mpa, evenly and spaced on the first branch pipe 1003, the second branch pipe 1004 and the third branch pipe 1005, and the aperture of the outlet is controlled between 0.4 and 0.6mm. The distance between the outlet and the human body is designed to be between 15 and 25 cm, which can ensure that more than 95% of the body area is sprayed to obtain better shower comfort.

[0145] Furthermore, regarding the layout of the pipeline 10, the pipeline 10 is arranged in the top interlayer of the shielding member 1. Compared with the separate arrangement of the pipeline 10, this design method can ensure the stability and durability of the pipeline 10. Through the support of the support member 7, the pipeline 10 located in the interlayer is stably supported by the support column on the support member 7, and the stability is further improved.

[0146] Since the pipeline 10 is located directly above the human body (lying flat), it can also be arranged around the human body, and water is sprayed from the outlet and evenly sprinkled on the human body, and then discharged through the drain port 6 to complete the entire bathing process. The design of the pipeline 10 can ensure that the water flow evenly and comfortably covers the entire body of the human body, further providing a comfortable bathing environment for the bather.

[0147] The overall use process of the bag-like structure is further described, which includes:

[0148] Water supply stage: First, the water pump pumps the external water source into the pipeline 10 to provide the required pressure water source for bathing;

[0149] Spraying stage: Spraying water is sprayed out through multiple outlets and evenly sprinkled on the person lying on the bottom mat to achieve comprehensive cleaning;

[0150] Drainage stage: the spray water flows along the multiple water paths formed on the bottom mat to the second end 202 and is discharged through the drain port 6;

[0151] Recycling: The discharged water can be recycled. After filtering and disinfection, the recycled water can be used for spraying again to achieve the recycling of water resources.

[0152] Furthermore, the base pad and the shielding member 1 can be designed to be integrated or detachable. The integrated type means that the base pad and the shielding member are integrally connected. To facilitate entry for bathers, a connecting structure such as a zipper, Velcro or a concealed button is provided on the shielding member 1, thereby facilitating bathers to partially open the shielding member 1 and enter the cabin 101 for bathing. The detachable type means that the base pad and the shielding member 1 are connected in a detachable manner, such as a zipper, Velcro, etc., so that bathers can lie directly on the base pad and then connect the shielding member 1 for bathing.

[0153] Furthermore, a heat-insulating layer is provided on the outside of the shielding member 1 to reduce the speed at which the temperature of the inner space of the bag-like structure drops.

[0154] The bag-like structure proposed in this embodiment can help the elderly or patients take a bath without moving the human body, reducing the risks of slipping, catching cold, etc. for bathers during traditional bathing and carrying processes, reducing the operation of bathing assistants, making bathing assistance easier, and allowing bathing to be achieved in many scenarios that cannot be achieved with traditional bathing equipment, such as outdoors and in cars. It has a simple structure and saves resources.

[0155] In summary, the ingenious design of the base pad is:

[0156] First, when the bather enters the cabin to take a bath, he lies on the bathing area of ​​the cushion. The cushion is trapezoidal in shape, so that the cabin formed by the cushion and the shield has a large space at the head end and a small space at the foot end, which is consistent with the contour of the human body lying down. The bottom wall of the bathing area is formed with a slope surface that tilts downward from the front end to the rear end, so that when the human body lies on the cushion, the front end is higher and the feet are lower, which increases the comfort of bathing. When the bather is sprayed in the cabin, the spray water flows down the slope surface and is concentrated in the first water storage tank, which is convenient for unified discharge or collection from the drain outlet. A water recovery point can also be set at the drain outlet to recover water at the recovery point, which is suitable for outdoor conditions where there is a lack of water resources. The recovered water can be filtered and reused. A water suction motor device can be connected to the recovery point to accelerate the recovery of water. At the same time, the spray water is concentrated in the first water storage tank, close to the human foot position, which is convenient for directly soaking the foot, making full use of the spray water, and providing a comfortable bathing environment for the bather.

[0157] Second, the drainage channel is a straight channel. The bottom of the straight channel is formed with a stepped surface and / or a wavy surface. The stepped surface forms a third water storage tank. When the water flows from high to low on the slope surface, when it impacts the step layer of each step surface, it will be blocked by the step layer and the water will be dispersed, which is conducive to the release of thermal energy by hot water, so that the thermal energy in the hot water can be fully utilized, which is conducive to keeping the cabin warm. The third water storage tank can continuously retain a certain amount of hot water, which is further conducive to the insulation state in the cabin. The drainage channel has curved channels with different bending directions. This design allows the water flow to have a longer flow path on the cushion body, which can fully release heat in the cabin, and can also form a certain resistance to the human body to prevent the human body from sliding down the bottom cushion.

[0158] Third, the connection position between the overflow tank and the first water tank is higher than the bottom position of the first water tank, so that the first water tank plays a sedimentation role. When the bather is taking a spray bath in the cabin, the water flows along the slope surface to the first water tank and continuously gathers in the first water tank. During the gathering process, most of the dirt in the water will settle to the bottom of the first water tank. When the water in the first outlet tank gathers to a higher water level, the bottom position of the second water tank is lower than the connection position between the overflow tank and the first water tank; the bottom height of the overflow tank is inclined downward from the first water tank to the second water tank, which is convenient for the water in the first water tank to flow to the second water tank, and will flow along the overflow tank into the second water tank. During the flow, it is further filtered by the filter net. The bottom position of the second water tank is lower than the bottom position of the first water tank. After the water is gathered in the second water tank, it can be reused, which saves water and makes full use of the heat of hot water. At the same time, there is no need to set the water tank too large to affect the lying space.

[0159] Fourth, the width of the first end of the cushion body relative to each other in the length direction is designed to be greater than the width of the second end, and the third end and the fourth end of the cushion body relative to each other in the width direction are relatively inclined, so that the cushion body as a whole is in a trapezoidal shape. The cushion body as a whole is in a trapezoidal shape, so that the cabin formed by it and the shielding member has a larger head end space and a smaller foot end space, which fits the contour of the human body lying posture, and the height of the cushion body gradually decreases from the first end to the second end, forming a slope structure, so that when the human body lies on the cushion body, the front end is higher and the feet are lower, thereby increasing the comfort of bathing. By designing the height of the third end to be greater than that of the bathing The height of the bathing area and the height of the fourth end are greater than the height of the showering area, so that when the bather is sprayed in the cabin, the spray water can be concentrated in the part between the third end and the fourth end and quickly discharged to the second end along the slope structure, and discharged from the second end. The cushion body is trapezoidal as a whole, which further makes the upper body of the bather have a wider space, and the spray water is not easy to accumulate. As the width of the cushion body gradually decreases from the head end to the foot end, the spray water gradually accumulates and is uniformly discharged at the drainage end, that is, the second end. The cushion body structure design can facilitate the uniform discharge or recovery of spray water, but is not easy to accumulate spray water, thereby further increasing bathing comfort.

[0160] Fifth, the sub-cushions on both sides are designed to be higher than the other sub-cushions, so that the height of the third end and the fourth end is greater than the height of the bathing area. When the bather is showered in the cabin, the shower water can be concentrated in the part between the third end and the fourth end and quickly discharged to the second end along the slope structure and then discharged from the second end. This can not only prevent water overflow on both sides of the bottom cushion, but also facilitate the rapid gathering and discharge of water.

[0161] It is further understood that in the present disclosure, "plurality" refers to two or more than two, and other quantifiers are similar thereto. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. The singular forms "a", "the" and "the" are also intended to include plural forms, unless the context clearly indicates other meanings.
