In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0052] In the present embodiment, a massage mat and a multifunctional spa machine are proposed. The multifunctional spa machine includes a main unit 20 and a massage mat 10 in the present embodiment. The main unit 20 further includes a first fluid supply device 21 and a second fluid supply device 22. The first fluid supply device 21 and the second fluid supply device 22 can supply the first fluid and the second fluid to the massage mat 10 respectively. The first fluid and the second fluid have different effects when acting on the human body.

[0053] refer to Figure 2-Figure 16As shown, the massage pad 10 includes a shell 11, in which a first cavity 11a and a second cavity 11b are separated and arranged, and the shell 11 is also provided with a first inlet 11e and a first outlet 11f connected to the first cavity 11a, and a second inlet 11g and a second outlet 11h connected to the second cavity 11b. The first fluid supply device 21 can supply the first fluid to the first cavity 11a through the first inlet 11e, and the second fluid supply device 22 can supply the second fluid to the second cavity 11b through the second inlet 11g. The shell 11 can be set to a circular, square or other shape according to needs. In this embodiment, in order to prevent the massage pad 10 from scratching the human body, the shell 11 is set to a circular shape.

[0054] The massage pad 10 can play different roles and meet the diverse needs of users. In this embodiment, the first fluid supply device 21 is a gas-liquid mixed supply device, that is, the first fluid is a gas-liquid mixture, and the second fluid supply device 22 is a gas supply device, that is, the second fluid is a gas. Then, the massage pad 10 can form bubble water and bubbles in the water at the same time, wherein the bubble water can bring deep cleaning of the user's pores, and the bubbles can play a massage role, meeting the diverse needs of users. It can be understood that bubble water and bubbles can be formed at the same time, or the second fluid supply device 22 or the first fluid supply device 21 can be closed according to user needs, so as to form bubble water or bubbles separately.

[0055] In other embodiments, the first fluid or the second fluid may also be a foam source, which can play a role in cleaning the skin surface.

[0056] refer to Figure 7 and Fig. 9 As shown, the massage pad 10 also includes a cutting member 12 and / or a microporous member 13, wherein the cutting member 12 is arranged at the first outlet 11f to further cut the gas in the gas-liquid mixture to form microbubble water to enhance the skin cleansing effect, and the microporous member 13 is arranged at the second outlet 11h to further divide the gas sprayed into the liquid through the second outlet 11h into a plurality of small bubbles.

[0057] Specifically, the cutting member 12 includes a first filter screen and a first mounting seat, the first mounting seat has a first mounting hole that is set through, and the first mounting seat is fixed to the first outlet 11f by a detachable method including but not limited to screw connection, plug-in connection, etc. The first filter screen is set in the first mounting hole of the first mounting seat, and the pores thereon are between 40-500 meshes, and the pores on the microporous member 13 are between 50-300um. The microporous member 13 can specifically use air stone, or other structures with gaps. The cutting member 12 is fixed to the housing 11 by a detachable connection, which is convenient for the later cleaning and replacement of the cutting member 12, especially the first filter screen.

[0058] In other embodiments, the cutting element 12 and the microporous element 13 may also be arranged at other positions of the massage pad 10, for example, the cutting element 12 is arranged at the first inlet 11e, the microporous element 13 is arranged at the second inlet 11g, or the cutting element 12 and the microporous element 13 are respectively arranged in areas where the gas-liquid mixture and the gas can flow through.

[0059] In this embodiment, the massage pad 10 also includes a first joint 14 connected to the shell 11. In order to reduce the volume of the massage pad 10, a first flow channel and a second flow channel separated from each other are provided in the first joint 14. One end of the first flow channel is connected to the first fluid supply device 21, and the other end is connected to the first cavity 11a through the first inlet 11e. One end of the second flow channel is connected to the second fluid supply device 22, and the other end is connected to the second cavity 11b through the second inlet 11g.

[0060] At the same time, in order to rationally utilize the surface space of the shell 11 and increase the coverage of the bubble water and bubbles, one of the first outlet 11f and the second outlet 11h is arranged on the outer side of the shell 11, and the other is arranged on the upper surface of the shell 11.

[0061] In this embodiment, a plurality of first outlets 11f are arranged at intervals along the circumference of the shell 11 on the outer side surface of the shell 11, and a plurality of second outlets 11h are arranged in a honeycomb shape on the upper surface of the shell 11. On this basis, the first cavity 11a is connected to the first outlet 11f through a first guide channel 11m extending radially, and a plurality of first guide channels 11m correspond one to one to each first outlet 11f. More specifically, the first outlet 11f includes a large diameter section and a small diameter section, wherein the small diameter section is connected to the first cavity 11a through the first guide channel 11m, the large diameter section is located at one end of the small diameter section away from the first cavity 11a, and the cutting member 12 is arranged in the large diameter section. The small diameter section can increase the flow rate of the gas-liquid mixture flowing to the cutting member 12, so that the gas-liquid mixture flows quickly to the cutting member 12.

[0062] In other embodiments, only one second outlet 11 h may be provided, and the microporous member 13 is installed at the second outlet 11 h to cut the gas flowing out through the second outlet 11 h into small bubbles.

[0063] It is worth noting that if the first cavity 11a and the second cavity 11b are in the same plane, under the premise of making the fluid flow area of ​​the second cavity 11b as large as possible (increasing the range of bubble massage), the second cavity 11 is set to be annular, and the first cavity 11a is located on the inner side of the second cavity 11b. The first guide channel 11m will cut off the second cavity 11b in the radial direction, making it difficult for the gas to flow through each second outlet 11h in sequence. Therefore, in this embodiment, the first cavity 11a and the second cavity 11b are separated from each other up and down, so as to avoid the first guide channel 11m affecting the flow of gas in the second cavity 11b. It can be understood that the separation of the first cavity 11a and the second cavity 11b up and down includes two possibilities: the first cavity 11a is below the second cavity 11b and the first cavity 11a is above the second cavity 11b.

[0064] It is understandable that the ring shape here is a broad concept, which can be either a square ring shape or a circular ring shape, and its specific shape is adapted to the shape of the housing 11. For example, if the housing 11 is set to be circular, then the second cavity 11b is set to be circular.

[0065] In order to prevent the liquid from flowing back to the second fluid supply device 22 through the second cavity 11b, the massage cushion 10 also includes a first one-way valve 17. The first one-way valve 17 only allows the fluid to flow from the second cavity 11b to the second outlet 11h. The first one-way valve 17 can be embedded in the second outlet 11h. In this embodiment, in order to reduce the manufacturing cost of the massage cushion 10, the second cavity 11b is located below the first cavity 11a, so that there is a gap between the top wall of the second cavity 11b and the top wall of the shell 11 in the height direction. A plurality of second mounting holes are formed through the top wall of the second cavity 11b. The first one-way valve 17 is mounted in each second mounting hole one by one, and the microporous member 13 is arranged in the above-mentioned gap and corresponds to all the second outlets 11h. Exemplarily, there are six second mounting holes distributed in a circular array.

[0066] refer to Figure 4 and Figure 8 As shown, in order to make full use of the use environment of the massage pad 10, such as water in a bathtub or a tub or other liquids mixed with medicines, a third cavity 11c and a third inlet 11i and a third outlet 11j connected to the third cavity 11c are also provided in the shell 11. The third cavity 11c is not connected to the first cavity 11a and the second cavity 11b. The third outlet 11j is used to connect to the liquid inlet end of the first fluid supply device 21. The first fluid supply device 21 can form a negative pressure in the third cavity 11c. The liquid in the use environment enters the third cavity 11c through the third inlet 11i and flows to the liquid inlet end of the first fluid supply device 21 through the third outlet 11j, thereby providing liquid for the first fluid supply device 21.

[0067] Specifically, in order to prevent foreign matter from entering the third cavity 11c along with the liquid through the third inlet 11i and flowing to the first fluid supply device 21 through the third cavity 11c and thus affecting the first fluid supply device 21, a first filter 18 is provided at the third inlet 11i.

[0068] In this embodiment, the first filter element 18 includes a second mounting seat 181 and a second filter screen 182. The second mounting seat 181 has a third mounting hole that is set through. The second filter screen 182 is set in the third mounting hole. The second mounting seat 181 is fixed in the third inlet 11i by means including but not limited to screw connection to facilitate replacement or cleaning of the first filter element 18.

[0069] The massage pad 10 also includes a first connector 14 connected to the shell 11. A third flow channel is also arranged in the first connector 14. One end of the third flow channel is connected to the third cavity 11c through the third outlet 11j, and the other end is connected to the liquid inlet end of the first fluid supply device 21. The third outlet 11j is arranged at the bottom of the shell 11.

[0070] Specifically, refer to Figure 3 and Figure 4 As shown, the second joint 15 and the third joint 16 are inserted into the first joint 14, the first flow channel is formed inside the second joint 15, the third flow channel is formed inside the third joint 16, and the gap between the first joint 14 and the second joint 15 and the third joint 16 is the second flow channel.

[0071] Optionally, a fourth cavity 11d which is not connected to the first cavity 11a, the second cavity 11b and the third cavity 11c is further provided in the shell 11, and a first port 11k and a second port 11l which are connected to the fourth cavity 11d are provided on the shell 11. The setting of the first port 11k and the second port 11l enables the fourth cavity 11d to be connected to the external environment, and the fourth cavity 11d can be filled with auxiliary materials with different functions as required, and the auxiliary materials include but are not limited to one or more of hydrogen-rich stone, VC balls, carbonate tablets, calcium sulfite filter materials and KDF filter materials, wherein the hydrogen-rich stone has antioxidant and anti-inflammatory effects on the skin, VC balls, carbonate tablets, calcium sulfite filter materials and KDF filter materials can remove heavy metals and residual chlorine in water, volcanic stone and medical stone can promote blood circulation, PP cotton and activated carbon filter materials can remove residual chlorine impurities and improve water quality, and aroma essential oils can provide a smell during massage to improve the massage atmosphere.

[0072] Specifically, the fourth cavity 11d is arranged in a circular shape and is located inside the first cavity 11a. A plurality of first openings 111 are arranged on the upper surface of the shell 11 and are honeycomb-shaped as a whole. A plurality of second openings 11k are arranged on the lower surface of the shell 11. In this embodiment, the first cavity 11a, the second cavity 11b and the fourth cavity 11d are arranged coaxially, and the first cavity 11a is also arranged in a ring shape.

[0073] In order to maintain the stability of the massage pad 10 in water, the massage pad 10 further includes a suction cup 19 . A plurality of suction cups 19 are disposed on the lower surface of the housing 11 to fix the massage pad 10 .

[0074] refer to Fig. 9 As shown, the shell 11 includes a base 111, a fixed cover, a closing plate 114 and a diverter plate 115, wherein a ring-shaped dividing rib 1121 is provided on the side of the fixed cover facing the base 111, and the fixed cover is connected to the base 111 and encloses an inner cavity by means including but not limited to plug-in and bolt connection, and the dividing rib 1121 divides the inner cavity into a first inner cavity and a second inner cavity, and the first inner cavity is the fourth cavity 11d.

[0075] In order to facilitate the replacement of auxiliary materials in the fourth cavity 11d according to user needs, the fixed cover includes a cover body 112 and an auxiliary material cover 113. The cover body 112 is provided with an installation opening arranged in alignment with the dividing rib 1121. The auxiliary material cover 113 is detachably connected to the cover body 112 to seal the above-mentioned installation opening. The second opening 111 is opened on the auxiliary material cover 113.

[0076] Considering that the auxiliary material is consumable, it needs to be replaced frequently. In this embodiment, the diameter of the installation opening is the same as the inner diameter of the separation rib 1121, and the auxiliary material cover 113 is fixedly connected with the separation rib 1121. Fig.16 As shown, an L-shaped buckle 1122 is provided on the inner wall of the separation rib 1121, and an L-shaped rotation buckle 1131 is provided on the outer wall of the auxiliary material cover 113. The buckle 1122 and the rotation buckle 1131 cooperate with each other to limit the auxiliary material cover 113 from being separated from the base 111 upwards. In order to limit the depth of the auxiliary material cover 113 entering the fourth cavity 11d, a stop bar 1123 is also provided on the inner wall of the separation rib 1121. When the upper surface of the auxiliary material cover 113 is flush with the upper surface of the cover body 112, the lower surface of the auxiliary material cover 113 abuts against the stop bar 1123. More specifically, there are four buckle buckles 1122 and four rotation buckles 1131 distributed in a circular array.

[0077] When the auxiliary material cover 113 is assembled to the mounting opening, the auxiliary material cover 113 is first placed in the fourth cavity 11d so that the auxiliary material cover 113 abuts against the stop bar 1123, and then the horizontally extending end of the rotating buckle 1131 is rotated to just below the horizontally extending end of the rotating buckle 1131, thereby limiting the auxiliary material cover 113 from upwardly separating from the mounting seat. When the auxiliary material cover 113 needs to be opened for replacement, the auxiliary material cover 113 only needs to be rotated in the reverse direction.

[0078] refer to Figure 5 , Figure 6 , Figure 9-Figure 15As shown, the first outlet 11f is arranged on the base 111, and the enclosure sheet 114 is arranged on the side of the diverter plate 115 facing away from the base 111 and is enclosed with the diverter plate 115 to form the first cavity 11a and the first guide channel 11m, and the diverter plate 115 is provided with a first guide port 115a connecting the first guide channel 11m and the first outlet 11f, and the base 111 and the diverter plate 115 are enclosed to form the second cavity 11b, the third cavity 11c, the second guide channel 11n connecting the first inlet 11e and the first cavity 11a, and the third guide channel 11o connecting the third outlet 11j and the third cavity 11c, and a fourth guide channel is further arranged below the second guide channel 11n, and an air outlet 111a is respectively arranged on the opposite sides of the fourth guide channel to connect the second cavity 11b and the second inlet 11g. The flow dividing plate 115 is also provided with a second flow guiding port 115 d which is connected with the second flow guiding channel 11 n and the first cavity 11 a .

[0079] After the gas-liquid mixture enters the shell 11 through the first inlet 11e, it flows through the second guide channel 11n, the second guide port 115d, the first cavity 11a, the first guide channel 11m, the first guide port 115a in sequence, and then flows to the first outlet 11f. After the gas enters the shell 11 through the second inlet 11g, it flows through the fourth guide channel, the air outlet 111a, the second cavity 11b, the first one-way valve 17, and the microporous member 13 in sequence, and then flows to the second outlet 11h.

[0080] Specifically, refer to Fig.14 As shown, the base 111 is coaxially provided with an annular first retaining rib 1111 and a second retaining rib 1112, which are arranged sequentially from the inside to the outside, and the first retaining rib 1111 and the second retaining rib 1112 are both in contact with the diverter plate 115, thereby forming a second cavity 11b between the first retaining rib 1111 and the second retaining rib 1112.
