[0003] When the inflatable massage pool is in use, it only needs to fill the inflatable chamber with gas to form a water holding space, and then inject a certain amount of water into the water holding space for use. The inflatable massage pool in the prior art needs to rely on an external air pump to inflate the inflatable chamber; after the inflatable massage pool is used, it is only necessary to drain the water in the water holding space and open the inflatable chamber to deflate. The prior art also uses an external air pump to speed up the deflation speed of the inflatable chamber.

[0004] In the prior art, the inflatable massage pool is inflated and deflated by external air pumps and air pumps, which has the disadvantages of being inconvenient to carry and complicated to operate. Utility Model Content

[0005] The purpose of the utility model is to solve the technical problems that the massage pool needs to carry extra equipment such as an air pump and an air pump in the prior art, which reduces the portability of the massage pool and also brings about complicated inflation and air extraction operations. The utility model provides a massage pool including an automatic inflation and deflation structure.

[0006] In order to solve the above technical problems, the embodiment of the utility model discloses a massage pool including an automatic inflation and deflation structure, comprising:

[0010] When the inflation and deflation module is in the inflation state, the first gas path is connected and the second gas path is closed; when the inflation and deflation module is in the exhaust state, the first gas path is closed and the second gas path is connected.

[0011] By adopting the above technical solution, by arranging the first air circuit and the second air circuit in the inflation and deflation module, the inflation and deflation module can be switched between the inflation state and the exhaust state by opening or closing different air circuits, that is, the inflation and exhaust functions are integrated into one, and the inflation and deflation module and the control unit are arranged in the inflation chamber. When the massage pool needs to be carried around, there is no need to carry additional inflation and deflation equipment, and inflation or deflation can be achieved through the inflation and deflation module, which can improve the portability and simple operation.

[0085] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0086] In some embodiments, see Figure 1 , Figure 2 The present application provides a massage pool 11 , comprising a first bottom wall 12 , which is disposed on one side of an inflatable chamber 111 of the massage pool 11 in a first direction X. Exemplarily, the inflatable chamber 111 encloses a side of a water containing space 13 along a circumferential direction R.

[0087] It is understandable that the inflatable chamber 111 can be enclosed into a circular water-containing space 13, or a rectangular, polygonal or other shaped water-containing space 13, and the present application does not limit this. When using the massage pool 11 provided by the present application, it is only necessary to first fill the inflatable chamber 111 with gas of a certain pressure so that the pool forms a water-containing space 13, and then fill the water-containing space 13 with water; after use, it is only necessary to completely discharge the gas in the inflatable chamber 111, and the massage pool 11 can be stored for easy carrying. It is understandable that the pools provided by the present application include but are not limited to massage pools and other products.

[0088] In some embodiments, the inflation chamber 111 includes a first side enclosure 1111, a second side enclosure 1112, a top 1113 and a second bottom wall 1114. Along the first direction X, the top 1113 and the second bottom wall 1114 are spaced apart. Along the second direction Y, the first side enclosure 1111 and the second side enclosure 1112 are spaced apart. The first side enclosure 1111 and the second side enclosure 1112 together enclose a water holding space 13. The inflation module 113 of the massage pool 11 is disposed on the first side enclosure 1111. Since the second side enclosure 1112 is in contact with the water in the water holding space 13, the inflation module 113 is disposed on the first side enclosure 1111, so that personnel can directly operate the inflation module 113.

[0089] Exemplarily, the top 1113 is arranged in an arc shape, and the first bottom wall 12 and the second bottom wall 1114 can be arranged integrally. It can be understood that the present application does not limit the shape of the top 1113. The charging and discharging module provided in the present application is detachably arranged on the first side wall 1111 by gluing, that is, the charging and discharging module 113 can be removed from the massage pool 11 to inflate other air chambers.

[0090] In some embodiments, a plurality of support portions 1115 are provided in the inflatable chamber 111, and the plurality of support portions 1115 are provided between the first side enclosure 1111 and the second side enclosure 1112, and the plurality of support portions 1115 are arranged at intervals along the third direction, so as to divide the inflatable chamber 111 into a plurality of small inflatable chambers, and the plurality of small inflatable chambers are interconnected. Exemplarily, the third direction may be the circumferential direction R, that is, the plurality of support portions 1115 are arranged at intervals along the circumferential direction R. It is understandable that the present application does not limit the extension state of the third direction, for example, the third direction may also extend in a straight line direction.

[0091] In some embodiments, see Figure 5 , Figure 7 Combined with Figure 2 The massage pool 11 provided in the present application includes an inflation chamber 111, a control unit 112 and an inflation and deflation module 113, wherein the control unit 112 and the inflation and deflation module 113 are both arranged in the inflation chamber 111 and electrically connected to the control unit 112, and the inflation and deflation module 113 includes a first air path a and a second air path b, the first air path a is used to deliver external gas into the inflation chamber 111, and the second air path b is used to discharge the gas in the inflation chamber 111; the inflation and deflation module 113 can switch between an inflation state and an exhaust state; when the inflation chamber 111 is in an inflation state, the first air path a is connected and the second air path b is closed; when the inflation chamber 111 is in an exhaust state, the first air path a is closed and the second air path b is connected.

[0092] In some embodiments, see Figure 3The inflation and deflation module 113 is disposed inside the control unit 112 and is electrically connected to the control unit 112. For example, a mounting hole 1123 is provided on the control unit 112, and the inflation and deflation module 113 is passed through the mounting hole 1123. The inflation and deflation module 113 can be directly operated through the mounting hole 1123, and the control unit 112 and the inflation chamber 111 are connected through the air pipe 1122.

[0093] By arranging the first air path a and the second air path b in the inflation and deflation module 113, the inflation and deflation module 113 can be switched between the inflation state and the exhaust state by opening or closing different air paths, that is, the inflation and exhaust functions are integrated into one, and the inflation and deflation module 113 and the control unit 112 are arranged in the inflation chamber 111. When the massage pool 11 needs to be carried around, there is no need to carry additional inflation and deflation equipment, and inflation or deflation can be achieved only through the inflation and deflation module 113, which can improve portability and simple operation.

[0094] In some embodiments, the control unit 112 includes a power supply unit (not shown in the figure) and a control unit (not shown in the figure). The control unit can control the power supply unit to supply power to the charging and discharging module to achieve accurate control of the inflation time, which can effectively prevent the massage pool from being overcharged and extend the life of the pool. Exemplarily, the control unit 112 includes a circuit board PCBA (Printed Circuit Board Assembly), and the charging and discharging module 113 is electrically connected to the control unit 112 through a cable 1121.

[0095] In some embodiments, see Figure 5 The charging and discharging module 113 includes a pressure-regulating gas circuit c, which is used to discharge part of the external gas in the first gas circuit a; the charging and discharging module 113 can switch between the charging state, the exhaust state, and the gas replenishing state. When the charging and discharging module 113 is in the gas replenishing state, the pressure-regulating gas circuit c is closed and the first gas circuit a is connected.

[0096] The pressure regulating gas circuit c can discharge part of the external gas in the first gas circuit a to adjust the gas pressure in the inflation chamber 111. When the inflation and deflation module is in the inflation state, the first gas circuit a is connected, and the pressure regulating gas circuit c is opened. When the inflation chamber 111 reaches the set pressure value, the pressure in the inflation chamber 111 forms a pressure balance with the pressure in the inflation and deflation module 113. At this time, the excess gas is discharged through the pressure regulating gas circuit c until the inflation stops, so as to avoid the excessive pressure in the inflation chamber 111 damaging the massage pool;

[0097] When the air pressure in the inflation chamber 111 is insufficient or the air pressure in the inflation chamber 111 needs to be increased (for example, from 2Kpa to 6kpa), the inflation and deflation module 113 switches to the air replenishing state. When the inflation and deflation module is in the air replenishing state, the first air path a is connected and the pressure regulating air path c is closed for air replenishment. The air replenishment pressure is greater than the equilibrium pressure value of inflation. All gases enter the inflation chamber through the first air path a to efficiently increase the air pressure in the inflation chamber 111 so that the inflation chamber 111 can reach a predetermined air pressure state.

[0098] In some embodiments, see Figure 4 , Figure 5 , Figure 6 Combined with Figure 2 The inflation and deflation module 113 includes a first shell 1131 and a second shell 1132. The second shell 1132 is arranged around the periphery of the first shell 1131. A first channel 1133 is provided between the first shell 1131 and the second shell 1132 for external air to enter the first shell 1131. A wind hole 1136 is opened on one side of the first shell 1131 in the second direction Y.

[0099] Exemplarily, a second one-way valve (not shown) is provided at the connection between the first channel 1133 and the outside of the inflation and deflation module 113 to enhance the air tightness of the inflation and deflation module 113. In some embodiments, a sealing cover 11321 is provided on the second housing 1132. When inflation is completed, the second one-way valve and the sealing cover 11321 are closed, which can play a double-layer sealing role and effectively prevent the massage pool 11 from leaking through the inflation and deflation module 113.

[0100] For example, see Figure 4 The second shell 1132 includes an extension section 11322, which is located on one side of the second shell 1132 in the first direction X. A manual exhaust hole 11323 is opened on the extension section 11322, and the manual exhaust hole 11323 directly connects the inside and outside of the inflation chamber 111. When exhaust is needed, the manual exhaust hole 11323 can also be opened to directly achieve exhaust.

[0101] In some embodiments, see Figure 5 , Figure 7The charging and discharging module 113 includes an operating component 114, which is arranged on the first shell 1131 and is used to switch the charging and discharging module 113 between an inflation state, an exhaust state, and an air supply state. The operating component 114 can switch between a first state, a second state, a third state, and a fourth state; in the first state, the first air circuit a and the pressure-regulating air circuit c are connected, the second air circuit b is closed, and the charging and discharging module is in an inflation state; in the second state, the first air circuit a is connected, the pressure-regulating air circuit c is closed, and the charging and discharging module is in an air supply state; in the third state, the first air circuit a is closed, the second air circuit b is connected, and the charging and discharging module is in an exhaust state; in the fourth state, the first air circuit a, the second air circuit b, and the pressure-regulating air circuit c are all closed.

[0102] In some embodiments, see Figure 4 , Figure 5 The operating component 114 includes a first button 1141, a second button 1142, and a third button 1143. Along the first direction X, the first button 1141, the second button 1142, and the third button 1143 are spaced apart on a side of the first shell 1131 away from the air hole 1136. The first button 1141, the second button 1142, and the third button 1143 are all slidably disposed on the first shell 1131 in the second direction Y.

[0103] Exemplarily, when the first button 1141 slides along the second direction Y toward the interior of the first shell 1131, the operating component 114 is in the first state, and the inflation and deflation module 113 is in the inflation state; when the second button 1142 slides along the second direction Y toward the interior of the first shell 1131, the operating component 114 is in the second state, and the inflation and deflation module 113 is in the inflation state; when the third button 1143 slides along the second direction Y toward the interior of the first shell 1131, the operating component 114 is in the third state, and the inflation and deflation module 113 is in the exhaust state; when the first button 1141, the second button 1142, and the third button 1143 are not pressed, the operating component 114 is in the fourth state, and the inflation and deflation module 113 is closed.

[0104] In some embodiments, see Figure 5 , Figure 7 The charging and discharging module 113 includes an air inlet channel 1134 and an air supply channel 1135. One end of the air inlet channel 1134 is connected to the first channel 1133, and the other end is connected to the air supply channel 1135. The air inlet channel 1134 is provided with a first air inlet 11341 and a second air inlet 11342, and the air supply channel 1135 is provided with a first air outlet 11351 and a second air outlet 11352. Exemplarily, the air inlet channel 1134 and the air supply channel 1135 are both provided in the first housing 1131, and external air can enter the air supply channel 1135 through the first channel 1133, the air hole 1136, and the air inlet channel 1134 in sequence.

[0105] For example, see Figure 5 , the external air passes through the first channel 1133, the wind hole 1136, the first air inlet 11341, and the second air outlet 11352 in sequence to enter the inflation chamber 111 to form a first air path a; the external air passes through the first channel 1133, the wind hole 1136, the first air inlet 11341, the first air outlet 11351, the wind hole 1136, and the first channel 1133 in sequence to form a pressure regulating air path c.

[0106] See also Figure 7 The gas in the inflation chamber 111 passes through the second air inlet 11342, the second air outlet 11352, the first air outlet 11351, the wind hole 1136, and the first channel 1133 in sequence to form a second air path b, or the gas in the inflation chamber 111 passes through the second air inlet 11342, the second air outlet 11352, the wind hole 1136, and the first channel 1133 in sequence to form a second air path b, or the gas in the inflation chamber 111 passes through the second air inlet 11342, the first air outlet 11351, the wind hole 1136, and the first channel 1133 in sequence to form a second air path b.

[0107] In some embodiments, see Figure 5 , Figure 7 The first button 1141 is used to control the start of the motor and the opening or closing of the first air path a. When the first button 11311 slides along the second direction Y toward the inside of the first shell 1131, the operating component 114 is in the first state, the first air inlet 11341 and the second air outlet 11352 are opened, the second air inlet 11342 is closed, the first air path a is opened, and the charging and discharging module 113 is in the charging state;

[0108] The second button 1142 is used to control the on or off of the pressure regulating gas circuit c. When the second button 11312 slides along the second direction Y toward the inside of the first shell 1131, the operating component 114 is in the third state, the first air inlet 11341 and the first air outlet 11351 are closed, the pressure regulating gas circuit c is closed, and the charging and discharging module 113 is in the air replenishing state;

[0110] In some embodiments, see Figure 7The inflation and deflation module 113 includes an air supply component 1137, which is arranged in the air supply channel 1135, and is used to suck the gas from the air inlet channel 1134 and send it to the first air outlet 11351 and the second air outlet 11352; or, the air supply component 1137 is used to suck the gas from the air inlet channel 1134 and send it to the first air outlet 11351; or, the air supply component 1137 is used to suck the gas from the air inlet channel 1134 and send it to the second air outlet 11352.

[0111] Exemplarily, the air supply assembly 1137 includes an impeller 11371, and a motor 11372 is provided between the air inlet channel 1134 and the air hole 1136 along the second direction Y. The transmission end 11373 of the motor 11372 extends along the second direction Y, passes through the air inlet channel 1134 and enters the air supply channel 1135, and is connected to the impeller 11371, and is used to drive the impeller 11371 to rotate, sucking the gas in the air inlet channel 1134 and sending it to the first air outlet 11351 and the second air outlet 11352, or the impeller 11371 sucks the gas in the air inlet channel 1134 and sends it to the first air outlet 11351, or sucks the gas in the air inlet channel 1134 and sends it to the second air outlet 11352. The control unit can control whether the power supply unit supplies power to the motor 11372 to realize the start and stop of the motor 11372, thereby obtaining the beneficial effect of controlling the inflation time and avoiding overshoot.

[0112] In some embodiments, see Figure 8 Combined with Figure 5 , Figure 6 The inflation and deflation module 113 includes an air duct 1138, which passes through the first channel 1133, the second shell 1132 and the first shell 1131 in sequence. Along the first direction X, one end of the air duct 1138 is connected to the inflation chamber 111, and the other end is connected to the interior of the first shell 1131.

[0113] In some embodiments, a first one-way valve and a first convex portion 11381 are provided in the air duct 1138, the first one-way valve includes a moving portion 11382 and an elastic diaphragm 113823, the moving portion 11382 is slidably provided on the first convex portion 11381 along the first direction X, the moving portion 11382 includes a first gap 113824, the elastic diaphragm 113823 covers the first gap 113824, and the air duct 1138 can be switched between an on state and a closed state; when the first button 1141, the second button 1142, and the third button 1143 are all stationary relative to the first housing 1131, the motor 11372 is turned off, the operating assembly 114 is in the fourth state, and the air duct 1138 is in the closed state;

[0114] For example, see Figure 7 , Figure 7a , Figure 8The movable portion 11382 includes a first abutting portion 113821 and a second abutting portion 113822, the second abutting portion 113822 can abut against the first convex portion 11381, the second abutting portion 113822 includes a first gap 113824, and the surface of the second abutting portion 113822 is covered with an elastic diaphragm 113823, a part of the elastic diaphragm 113823 is fixedly connected to the second abutting portion 113822, and the part of the elastic diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 can be blown open under the pressure of the gas inside the first shell 1131. When there is no gas flow inside the first shell 1131, When the air-filled chamber 111 is inflated, the portion of the elastic diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 can automatically recover to a position covering the first gap 113824 under the action of elastic force, so that the gas in the air-filled chamber 111 cannot flow into the interior of the first shell 1131 through the first gap 113824. In addition, when there is no airflow from the interior of the first shell 1131 to the air-filled chamber 111, the gas pressure in the air-filled chamber 111 can also enable the portion of the elastic diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 to automatically recover to a position covering the first gap 113824 under the action of elastic force.

[0115] In some embodiments, the second abutment portion 113822 is a circular plate ( Figure 6 As shown), when the second abutment portion 113822 is in contact with the first convex portion 11381 and the elastic diaphragm 113823 is completely in contact with the surface of the second abutment portion 113822, the air duct 1138 is in a closed state, so that the gas cannot flow between the inflation and deflation module 113 and the inflation chamber 111 through the air duct 1138.

[0116] When the second abutting portion 113822 is arranged away from the first convex portion 11381 along the first direction X, the air duct 1138 is in a conducting state, and a second gap is formed between the second abutting portion 113822 and the first convex portion 11381, and the gas can flow between the inflation and deflation module 113 and the inflation chamber 111 through the second gap; or, when the second abutting portion 113822 abuts against the first convex portion 11381, when the part of the diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 is blown open under the action of the airflow, the gas can enter the inflation chamber 111 through the first gap 113824 on the second abutting portion 113822. It can be understood that the second abutting portion 113822 can also be a rectangular shape, etc., and the present application does not limit this.

[0117] In some embodiments, reference Figure 8 , Fig. 9 Combined with Figure 7 , Figure 7aThe inflation and deflation module 113 includes a first movable member 1139, and the first movable member 1139 has a first position and a second position in the second direction Y. The first movable member 1139 includes a first portion 11391 and a second portion 11392. The first portion 11391 and the second portion 11392 are spaced apart along the second direction Y. When the inflation and deflation module 113 is in the inflation state or the gas replenishment state, the first movable member 1139 is located at the first position (such as Fig. 9 As shown), the first part 11391 is located between the air inlet channel 1134 and the air duct 1138, and is used to close the second air path b and open the first air path a.

[0118] Exemplarily, the first movable member 11391 is connected to the first button 1141 via a first connecting plate 11395, and the first connecting plate 11395 is extended along the second direction Y. When the first button 1141 slides along the second direction Y toward the interior of the first shell 1131, the first movable member 1139 is driven to move along the second direction Y by the first connecting plate 11395.

[0119] When the first button 11311 slides along the second direction Y toward the interior of the first shell 1131, the operating component 114 is in the first state, the first connecting plate 11395 drives the first movable member 11391 to move to the first position, and the gas inside the first shell 1131 can cause the elastic diaphragm 113823 to tilt along the first direction X toward one side of the inflation chamber 111, so that the air flow can flow into the inflation chamber 111 through the first gap, the inflation and deflation module is in the inflation state or the air replenishment state, and the air duct 1138 is in the conduction state.

[0120] When the third button 11313 slides along the second direction Y toward the interior of the first shell 1131, the operating component 114 is in the third state, the first movable member 1139 moves to the second position, the second part 11392 drives the movable part 11382 to slide along the first direction X away from the first shell 1131, the charging and discharging module is in the exhaust state, and the air duct 1138 is in the conducting state. In some embodiments, the first part 11391 includes a first vertical plate 113911 and a first horizontal plate 113912, and the first vertical plate 113911 and the first horizontal plate 113912 are connected to form an "L" shape, and the second part 11392 includes a second vertical plate 113921 and a second horizontal plate 113922, and the second vertical plate 113921 and the second horizontal plate 113922 are connected to form an "L" shape, wherein the first horizontal plate 113912 and the second horizontal plate 113922 are spaced apart along the second direction Y, and the first horizontal plate 113912 and the second horizontal plate 113922 are connected by a connecting plate 11393, and the first horizontal plate 113912, the second horizontal plate 113922, and the connecting plate 11393 together enclose a second channel 11394 for gas to pass through.

[0121] like Fig. 9 As shown, when the first movable member 1139 is located in the first position, the first vertical plate 113911 is attached to the side wall of the first shell 1131, one end of the second channel 11394 is connected to the air duct 1138, and the other end is connected to the air supply channel 1135, and the second vertical plate 113921 is arranged between the second air inlet 11342 and the air duct 1138 to close the second air path b, and the charging and discharging module 113 is in an inflating state or a replenishing state. At this time, the external gas passes through the first channel 1133, the first air inlet 11341, the second air inlet 11342, and the second air outlet 11352 in sequence to form the first air path a; the external gas passes through the first channel 1133, the first air inlet 11341, the second air inlet 11342, and the first air outlet 11351 in sequence to form a pressure regulating air path c.

[0122] like Fig.10 As shown, when the first movable member 1139 is located in the second position, the second vertical plate 113921 is attached to the side wall of the first shell 1131, one end of the second channel 11394 is connected to the air duct 1138, and the other end is connected to the air inlet channel 1134, the first vertical plate 113911 is arranged between the second air outlet 11352 and the air duct 1138 to close the first air path a, the second horizontal plate 113922 is arranged between the air inlet channel 1134 and the second vertical plate 113921, so that the first air inlet 11341 in the first air path a is also kept closed, and the charging and discharging module 113 is in the exhaust state.

[0123] In some embodiments, see Figure 7 , along the first direction X, the first abutting portion 113821 includes an inclined surface 113831. When the first moving member 1139 is located at the second position, the second portion 11392 abuts against the inclined surface 113831, and the air duct 1138 is in a conducting state. Exemplarily, when the first moving member 1139 switches from the first position to the second position, the second vertical plate 113921 abuts against the inclined surface 113831, pushing the moving portion 11382 to be arranged away from the first convex portion 11381 along the first direction X. In this way, when exhausting, the gas can enter the air inlet channel 1134 through the air duct 1138, without the need to open an additional exhaust port, further reducing the complexity and cost of the structure.

[0124] In some embodiments, see Figure 7 , Figure 8The inflation and deflation module 113 includes a second movable member 1130, and the second movable member 1130 has a third position and a fourth position in the second direction Y; when the second movable member 1130 is located at the third position, along the second direction Y, the second movable member 1130 and the first air outlet 11351 are spaced apart, and the inflation and deflation module 113 is in an inflation state or an exhaust state; when the second movable member 1130 is located at the fourth position, the second movable member 1130 and the first air outlet 11351 are closely attached, and the inflation and deflation module 113 is in an air replenishment state.

[0125] Exemplarily, the second movable member 1130 is connected to the second button 1142 via a second connecting plate 11302, and the second connecting plate 11302 extends along the second direction Y. When the second button 1142 slides along the second direction Y toward the interior of the first shell 1131, the second movable member 1130 is driven to move along the second direction Y via the first connecting plate 11395.

[0126] When the second button 1142 is long pressed and located inside the first shell 1131 , the second moving member 1130 moves to the fourth position, and the second moving member 1130 is disposed in close contact with the first air outlet 11351 .

[0127] When the second button 1142 is released and slides along the second direction Y away from the interior of the first shell 1131 , the second moving member 11312 moves to the third position. Along the second direction Y, the second moving member 1130 and the first air outlet 11351 are spaced apart.

[0128] In some embodiments, the second movable member 1130 has a second convex portion 11301 on one side close to the second air outlet 11351, and the second convex portion 11301 is set in a conical shape. When the second movable member 1130 is in the fourth position, the second convex portion 11301 passes through the second air outlet 11351 and is inserted into the air supply channel 1135. By changing the depth of the second convex portion 11301 inserted into the air supply channel 1135, the air supply volume of the second air outlet 11351 can be changed, so that the size of the air pressure sent into the inflation chamber 111 can be adjusted. It can be understood that the second convex portion 11301 can also be set in a cylindrical shape, etc., and the present application does not limit this.

[0129] In some embodiments, the interior of the first shell 1131 includes a return spring (not shown in the figure), and the first return spring is connected to the second button 1142. When the second button 1142 slides along the second direction Y toward the interior of the first shell 1131, the return spring is compressed in the second direction Y. Therefore, it is necessary to press the second button 1142 for a long time to keep the second moving member 1130 always located inside the first shell 1131. When the gas replenishment is completed, the second button 1142 is released, and under the action of the return spring, the second button 1142 slides along the second direction Y away from the interior of the first shell 1131.

[0130] The third button 1143 is connected to the first button 11313. When the third button 1143 slides along the second direction Y toward the interior of the first shell 1131, the first button 11313 and the shell 1131 remain relatively still or the first button 11313 slides along the second direction Y away from the interior of the first shell 1131; when the first button 11313 slides along the second direction Y toward the interior of the first shell 1131, the third button 1143 and the shell 1131 remain relatively still or the third button 1143 slides along the second direction Y away from the interior of the first shell 1131.

[0131] In order to further illustrate the process of switching the working state of the inflation and deflation modules when the operating component is a button, Figure 5 , Figure 7 , Figure 8 Discuss:

[0132] When it is necessary to inflate the inflation chamber 111, press the first button 11313 to locate the first movable member 1139 in the first position, open the first air inlet 11341, close the second air inlet 11342, and automatically enter the inflation chamber 111 through the first channel 1133, the air hole 1136, the first air inlet 11341, the second air outlet 11352, and the air duct 1138 (i.e., the first air path a); at this time, the first air outlet 11351 is in an open state, and part of the gas is discharged through the first channel 1133, the first air inlet 11341, the second air inlet 11342, and the first air outlet 11351 (i.e., the pressure regulating air path c) in sequence, and does not enter the inflation chamber 111, so as to balance the air pressure of the inflation chamber 111 and the outside world, and avoid damage to the inflation chamber 111 due to overcharging. At this time, the second vertical plate 113921 is arranged between the second air inlet 11342 and the air duct 1138 to close the second air path b.

[0133] When the air pressure in the inflation chamber 111 needs to be increased, long press the second button 1142 to place the second movable member 1130 in the fourth position, and the first air outlet 11351 is in a closed state. All external air is automatically filled into the inflation chamber 111 through the air duct 1138, thereby increasing the gas in the inflation chamber 111.

[0134] When the gas in the inflation chamber 111 needs to be discharged, the third button 1143 is pressed to make the first movable part 1139 be located in the second position, the first air inlet 11341 is closed, and the second air inlet 11342 is opened. The gas in the inflation chamber 111 is automatically discharged into the external environment through the air duct 1138, the second air inlet 11342, the second air outlet 11352 and the first air outlet 11351, the air hole 1136 and the first channel 1133 in sequence.

[0135] In addition, it should be noted that the present application does not limit the internal structure of the inflation and deflation module 113 and the specific form of the operating component 114. For example, in some embodiments, refer to Fig.11 , Fig.11a The operating assembly 114 includes a first rotating portion 1144, a second rotating portion 1145, and a third rotating portion 1146. The first rotating portion 1144 is rotatably disposed on the first housing 1131. Along the second direction Y, the second rotating portion 1145 is disposed on one side of the first rotating portion 1144. Along the first direction X, the third rotating portion 1146 is disposed on one side of the first rotating portion 1144. The second rotating portion 1145 and the third rotating portion 1146 can rotate with the first rotating portion 1144.

[0140] In some embodiments, see Fig.10b , Fig.11 , Fig.15 The inflation and deflation module 113 includes a first shell 1131 and a second shell 1132, the second shell 1132 is arranged around the periphery of the first shell 1131, and the first shell 1131 is provided with a plurality of air holes 1136 on one side of the operating assembly 114 in the second direction Y, and the plurality of air holes 1136 are arranged between the first shell 1131 and the second shell 1132. It can be understood that at this time, the plurality of air holes 1136 as a whole form the first channel in some of the aforementioned embodiments, which is used for external air flow to enter the interior of the first shell 1131. Exemplarily, the plurality of air holes 1136 include air holes 1136 arranged opposite to each other in pairs along the third direction Z, and the plurality of air holes 1136 are arranged at intervals along the first direction X. Fig.15 Two groups of air holes 1136 are shown, each group of air holes 1136 includes eight air holes 1136, and the eight air holes 1136 are arranged in the first shell 1131 at intervals along the first direction X. It can be understood that the number of air holes in each group of air holes 1136 can also be 7, 9, 10, etc., and the present application does not limit this.

[0141] In some embodiments, see Fig.15 The interior of the first shell 1131 is divided into an upper chamber 11314 and a lower chamber 11315. The upper chamber 11314 and the lower chamber 11315 are connected via a connecting hole 11316. The air hole 1136 connects the upper chamber 11314 with the outside atmosphere. External gas enters the lower chamber 11315 via the air hole 1136, the upper chamber 11314, and the connecting hole 11316 in sequence.

[0142] For example, see Fig.10bThe second shell 1132 includes an extension section 11322, which is located on one side of the second shell 1132 in the first direction X. An exhaust hole 11323 is provided on the extension section 11322, and the exhaust hole 11323 directly connects the inside and outside of the inflation chamber 111. When exhaust is needed, the exhaust hole 11323 can also be opened to directly achieve exhaust.

[0143] In some embodiments, see Fig.11 , Fig.15 The charging and discharging module includes an air inlet channel 1134 and an air supply channel 1135. Along the second direction Y, one end of the air inlet channel 1134 is connected to the air hole 1136 through the connecting hole 11316, and the other end is connected to the air supply channel 1135. The air inlet channel 1134 is provided with a first air inlet 11341. It can be understood that the present application does not limit the number of air inlets provided in the air inlet channel 1134, and only needs to be able to control the first air path a, the second air path b, and the pressure regulating air path c. The air supply channel 1135 is provided with a first air outlet 11351 and a second air outlet 11352. Exemplarily, the air inlet channel 1134 and the air supply channel 1135 are both arranged in the first shell 1131, and external air can enter the air supply channel 1135 through the air hole 1136 and the air inlet channel 1134 in sequence.

[0144] In some embodiments, see Fig.11 , Fig.15 Combined with Figure 7aThe inflation and deflation module 113 includes an air duct 1138. Along the first direction X, one end of the air duct 1138 is connected to the inflation chamber 111, and the other end is connected to the interior of the first shell 1131. A movable portion 11382 is provided in the air duct 1138. The movable portion 11382 can slide along the first direction X. The movable portion 11382 includes a first abutting portion 113821 and a second abutting portion 113822. The second abutting portion 113822 can abut against the first convex portion 11381 of the air duct 1138. The second abutting portion 113822 includes a first gap 113824, and the surface of the second abutting portion 113822 is covered with an elastic diaphragm 113823. Part of the elastic diaphragm 113823 is fixedly connected to the second abutting portion 113822. The part of the elastic diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 can be moved under the pressure of the gas inside the first shell 1131. When the first shell 1131 is blown open, when no gas flows toward the inflation chamber 111 from the inside of the first shell 1131, the portion of the elastic diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 can automatically restore to a position covering the first gap 113824 under the action of elastic force, so that the gas in the inflation chamber 111 cannot flow into the inside of the first shell 1131 through the first gap 113824. In addition, when no airflow flows toward the inflation chamber 111 from the inside of the first shell 1131, the gas pressure in the inflation chamber 111 can also enable the portion of the elastic diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 to automatically restore to a position covering the first gap 113824 under the action of elastic force.

[0145] When the second abutting portion 113822 is arranged away from the first convex portion 11381 along the first direction X, the air duct 1138 is in a conducting state, and a second gap is formed between the second abutting portion 113822 and the first convex portion 11381, and the gas can flow between the inflation and deflation module 113 and the inflation chamber 111 through the second gap; or, when the second abutting portion 113822 abuts against the first convex portion 11381, the part of the elastic diaphragm 113823 that is not fixedly connected to the second abutting portion 113822 is blown open by the action of the airflow, and the gas can enter the air duct 1138 through the first gap 113824 on the second abutting portion 113822, and then flow between the inflation and deflation module 113 and the inflation chamber 111. In some embodiments, refer to Fig.11 , Fig.15, along the first direction X, the end of the second abutting portion 113822 away from the first abutting portion 113821 is further provided with a first spring (not shown in the figure). When the second abutting portion 113822 is arranged away from the first convex portion 11381 along the first direction X, the first spring is compressed in the first direction X, and the gas in the inflatable chamber 111 can be discharged through the air duct 1138; when there is no need to discharge the gas in the inflatable chamber 111, under the action of the restoring force of the first spring, the second abutting portion 113822 is arranged in contact with the first shell 1131, so that the air duct 1138 is closed, and at this time, the gas can only unidirectionally break the elastic diaphragm 113823 from the inside of the first shell 1131 and flow into the inflatable chamber 111. Exemplarily, along the first direction X, the end of the first abutting portion 113821 away from the second abutting portion 113822 is arranged in a truncated cone shape. It can be understood that the present application does not limit the shape of the end of the first abutment portion 113821 away from the second abutment portion 113822. For example, it can also be set in a conical shape.

[0146] In some embodiments, reference Fig.15 , Fig.11a , Fig.11b The inflation and deflation module 113 includes a first movable member 1139, and the first movable member 1139 has a first position in the second direction Y (such as Fig.15 as shown) and a second position (as Fig.11a , Fig.11b , Fig.17 As shown), the first moving member 1139 includes a first part 11391 and a second part 11392. Along the second direction Y, the first part 11391 and the second part 11392 are spaced apart from each other, and a second channel 11394 is provided between the first part 11391 and the second part 11392.

[0147] Exemplarily, the second portion 11392 is in the shape of an inclined plate, and along the second direction Y, one side of the second portion 11392 can abut against the second rotating portion 1145, and the other side can abut against the first abutting portion 113821. Exemplarily, a third convex portion 11396 is provided on the side of the second portion 11392 abutting against the second rotating portion 1145, and a fourth convex portion 11397 is provided on the side of the second portion 11392 abutting against the first abutting portion 113821, the fourth convex portion 11397 abuts against the first abutting portion 113821, and the third convex portion 11396 abuts against the second rotating portion 1145. The second rotating portion 1145 is in an arc shape, and its projection in the first direction X is roughly triangular, so as to facilitate pushing the second portion 11392 to move downward along the second direction Y.

[0148] In some embodiments, see Fig.15 , Fig.17 Combined with Fig.11aThe second part 11392 is provided with baffles 11398 on both sides of the third direction Z. When the first movable member 1139 is in the first position, the baffle 11398 and the connecting hole 11316 are spaced apart in the second direction Y, and the connecting hole 11316 is opened; when the first movable member 1139 is in the second position, the baffle 11398 covers the connecting hole 11316, the connecting hole 11316 is closed, and the upper chamber 11314 and the lower chamber 11315 are not connected.

[0149] For example, see Fig.15 , Fig.11b , the first moving member 1139 is slidably disposed on the first housing 1131 along the second direction Y, the housing 1131 includes a fixing portion 11311, the fixing portion 11311 is extended along the second direction Y, and the first portion 11391 is slidably disposed on the fixing portion 11311 along the second direction Y. Exemplarily, a second spring (not shown in the figure) capable of contracting or extending along the second direction is disposed between the fixing portion 11311 and the first portion 11391, when the second rotating portion 1145 rotates to the second rotation position, the second rotating portion 1145 abuts against the first moving member 1139, and the second rotating portion 1145 pushes the first moving member 1139 to move downward along the second direction Y, at which time the second spring is compressed, and the first moving member 1139 moves to the second position; when the second rotating portion 1145 does not abut against the first moving member 1139, the second spring moves upward along the second direction Y, so that the first moving member 1139 returns to the first position.

[0150] When the inflation and deflation module 113 is in the inflation state or the gas replenishment state, the first moving member 1139 is located at the first position (eg Fig.15 As shown in FIG. 1 ), along the first direction X, the two ends of the second channel 11394 are connected to the air supply channel 1135 and the inflation chamber 111, respectively, for opening the first air path a. When the inflation and deflation module 113 is in the exhaust state, the first moving member 1139 is located in the second position (as shown in FIG. Fig.11a , Fig.11b , Fig.17 As shown), along the first direction X, the two ends of the second channel 11394 are connected to the interior of the first shell 1131 and the inflation chamber 111 respectively, for opening the second air path b and closing the first air path a.

[0151] For example, see Fig.11 , Fig.15 , Fig.16When the third rotating part 1145 is not in contact with the first moving part 1139, the external air enters the air-filled chamber 111 through the air hole 1136, the upper chamber 11314, the connecting hole 11316, the lower chamber 11315, the first air inlet 11341, the second air outlet 11352, the second channel 11394, and the air duct 1138 to form the first air path a. When the operating component 114 is in the first state, the first air inlet 11341 and the second air outlet 111352 are open, the second channel 11394 is closed (equivalent to the second air inlet being closed in some of the aforementioned embodiments), and the first air path a is connected;

[0152] See also Fig.11 , Fig.16a Combined with Fig.15 When the second rotating part 1146 is not in contact with the first air outlet 11351 , external air can sequentially pass through the air hole 1136 , the upper chamber 11314 , the connecting hole 11316 , the lower chamber 11315 , the first air inlet 11341 , the first air outlet 11351 , and the air hole 1136 to form a pressure regulating air path c.

[0153] See also Fig.11 , Fig.16 , Fig.17 , the gas in the air-filled chamber 111 passes through the second channel 11394, the first air inlet 11341, the first air outlet 11351 and the second air outlet 11352 in sequence, and is finally discharged through the air hole 1136 to form a second air path b. It can be understood that the first air inlet 11341 can achieve the function of the second air inlet in some of the aforementioned embodiments, that is, the gas in the air-filled chamber is sent to the air inlet channel 1134, so in this embodiment, no second air inlet is separately provided.

[0154] In order to further illustrate the process of switching the working state of the inflation and deflation modules when the operating component is a button, Fig.15 , Fig.16 , Fig.17 And refer to Fig.11 , Fig.11a Discuss:

[0155] like Fig.15 , Fig.16As shown, when it is necessary to inflate the inflation chamber 111, the second rotating part 11442 is rotated. At this time, the second rotating part 1145 and the third rotating part 1146 arranged on the first rotating part 11441 rotate along with the rotation of the second rotating part 11442, and finally the first rotating part 1144 is rotated as a whole to the first rotating position. At this time, the third rotating part 1145 does not abut against the third convex part 11396 of the second part 11392, so that the two ends of the second channel 11394 in the first direction X are respectively connected to the second air outlet 11352 and the air duct 1138. When external air flows into the second channel 11394, the thrust of the external air 11394 can make the part of the elastic diaphragm 113823 that is not fixedly connected to the second abutting part 113822 be blown open under the action of the airflow, and the air duct 1138 and the inflation chamber 111 are connected. The chamber 111 is connected, and external air automatically enters the inflation chamber 111 through the air hole 1136, the upper chamber 11314, the connecting hole 11316, the lower chamber 11315, the first air inlet 11341, the second air outlet 11352, the second channel 11394, and the air duct 1138 (i.e., the first air path a) in sequence; at the same time, the second rotating part 1146 does not abut against the first air outlet 11351, and the first air outlet 11351 is in an open state. Part of the gas is discharged through the air hole 1136, the upper chamber 11314, the connecting hole 11316, the lower chamber 11315, the first air inlet 11341, the first air outlet 11351, and the air hole 1136 (i.e., the pressure regulating air path c) in sequence, and does not enter the inflation chamber 111, so as to balance the air pressure of the inflation chamber 111 and the outside world, and avoid damage to the inflation chamber 111 due to overcharging. In addition, when the first rotating portion 1144 rotates to the first rotating position as a whole, the gas in the inflation chamber 111 cannot pass through the second channel 11394 and enter the first channel 1133 through the air hole 1136, that is, the second gas path b is in a closed state at this time.

[0156] like Fig.13 , Fig.16a As shown, when the air pressure in the inflation chamber 111 needs to be increased, the second rotating part 11442 is continuously rotated to rotate the first rotating part 1144 as a whole to the second rotating position. At this time, the third rotating part 1145 does not abut against the third convex part 11396 of the second part 11392, and the two ends of the second channel 11394 in the first direction X are respectively connected to the second air outlet 11352 and the air duct 1138, and the second rotating part 1146 abuts against the first air outlet 11351 ( Fig.13As shown), the first air outlet 11351 is in a closed state (i.e., the pressure regulating air circuit c is in a closed state), and the external air is automatically filled into the inflation chamber 111 through the air hole 1136, the upper chamber 11314, the connecting hole 11316, the lower chamber 11315, the first air inlet 11341, the second air outlet 11352, the second channel 11394, and the air duct 1138 (i.e., the first air circuit a) in sequence, thereby increasing the gas in the inflation chamber 111.

[0157] like Fig.17 , Fig.17a As shown, when the gas in the inflation chamber 111 needs to be discharged, the second rotating part 11442 continues to rotate, and the first rotating part 1144 is rotated as a whole to the third rotation position. At this time, the third rotating part 1145 abuts against the third convex part 11396 of the second part 11392. In the process of rotating to the third rotation position, the first part 11391, the second part 11392 and the second channel 11394 all move downward along the second direction Y, and the second spring is compressed in the second direction. Even if the first moving member 1139 is located in the second position, the connecting hole 11316 is closed. In the process of the second part 11392 moving downward along the second direction Y, the fourth convex part 11397 ( Fig.11b (shown) pushes the first abutting portion 113821, so that the first abutting portion 113821 and the second abutting portion 113822 move together along the first direction X away from the first shell 1131, so that the first spring is compressed in the first direction X, so that the gas-filled chamber 111 is connected with the second channel 11394, and the gas in the gas-filled chamber 111 is automatically discharged into the external environment through the second channel 11394, the lower chamber 11315, the first air inlet 11341, the second air outlet 11352 and the first air outlet 11351, and the air hole 1136 (i.e., the second air path b) in sequence. In addition, when the first rotating portion 1144 is rotated as a whole to the third rotating position, the external gas cannot enter the gas-filled chamber 111 through the second channel 11394, that is, at this time, the first air path a is in a closed state.

[0158] like Fig.11 , Fig.15 , Fig.16 As shown, when the charging and discharging module needs to be closed, the second rotating part 11442 continues to rotate, and the first rotating part 1144 is rotated to the fourth rotation position as a whole. At this time, the motor 11372 stops working, and no external gas flows into the first shell 111 (that is, the first gas path a and the pressure regulating gas path c are closed). Under the action of the restoring force of the second spring, the first part 11391, the second part 11392 and the second channel 11394 all move upward along the second direction Y to restore to the first position (that is, the second gas path b is closed). At this time, the fourth convex part 11397 ( Fig.11bAs shown in the figure, the second abutment portion 113821 is not abutted against the first abutment portion 113821. Under the action of the restoring force of the first spring, the second abutment portion 113822 moves along the first direction X close to the first shell 1131 and abuts against the first protrusion 11381, and the air duct 1138 is not connected to the inflation chamber 111.

[0159] Although the present invention has been illustrated and described with reference to certain preferred embodiments of the present invention, it should be understood by those skilled in the art that the above contents are further detailed descriptions of the present invention in combination with specific embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions.
