Description

Technical Field

[0001] This utility model relates to the field of air valve control technology for airbag massage devices, and in particular to a combined integrated valve. Background Technology

[0002] With increasing health awareness and improved living standards, small, portable home massagers, such as massage shawls, massage pillows, and massage cushions, are becoming increasingly popular. These products are widely welcomed by consumers due to their ease of use and affordable prices. To achieve a comfortable massage experience similar to the kneading and pressing of human hands, most of these products on the market currently use airbags as their core driving mechanism. The inflation and deflation of the airbags simulates the pressing and releasing motions of fingers.

[0003] To enhance the precision of massage, cover more comprehensive areas, and simulate more complex massage techniques, the design trend of modern portable massagers is to increase the number of airbags and enable their independent or combined control. For example, to achieve multiple massage modes such as "wave" and "point" massage, the massager may need to have dozens or even more small airbags inside, and they are required to perform sequential actions according to preset programs.

[0004] However, the current mainstream technology for achieving independent control of multiple airbags involves equipping each airbag or group of airbags with an independent electromagnetic valve, and connecting these valves to the air pump through a complex network of plastic or rubber tubing. This "one-to-one" or "one-to-several" control mode reveals its inherent technical shortcomings as the number of airbags increases. The space constraints are a significant challenge: small portable massagers have extremely limited internal space. Numerous independent electromagnetic valves and a complex network of air pipes occupy a large amount of internal space, which not only limits the development of thinner and more compact products but also contradicts the original design principle of "portability." Designers often have to make difficult trade-offs between functional complexity and structural dimensions.

[0005] The assembly process is complex and inefficient: During the assembly stage, workers need to precisely install dozens of air valves onto circuit boards or mounting bases and connect the same number of air hoses. This process is extremely tedious, requires high precision in manual operation, and is difficult to automate, severely slowing down the production cycle and resulting in low production efficiency.

[0006] Cost pressures have increased significantly: each solenoid valve is an independent precision component, and its procurement cost is considerable. At the same time, the complex internal structure and cumbersome assembly process directly drive up labor and management costs. This makes it difficult to control the final selling price of multi-functional, multi-airbag massagers, weakening their market competitiveness.

[0007] Increased reliability risks: Numerous valve interfaces and tubing connections mean a greater potential for leakage. A leaky seal at any interface or a malfunctioning valve could lead to partial or complete loss of the massage function, impacting the product's long-term reliability and user experience. Utility Model Content

[0008] The technical problem to be solved by this utility model is to provide a combined integrated valve that is cost-effective, small in size, and can greatly reduce the difficulty of assembly.

[0009] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a combined integrated valve, comprising a row of base plates and a plurality of solenoid valves fixedly mounted on the row of base plates in a straight array, and further comprising an air intake and an air exhaust. The air intake includes an exhaust body, a main air intake pipe opened in the exhaust body, a plurality of branch pipes communicating with the side wall of the main air intake pipe, and a first exchange chamber disposed at the end of the branch pipes. The lower end of one branch pipe corresponds to the valve core of one solenoid valve. The end of the branch pipe and the outer end of the valve core are located in the first exchange chamber. When the valve core extends, the outer end of the valve core seals against the end of the branch pipe. When the valve core retracts, there is a gap between the outer end of the valve core and the end of the branch pipe. An exhaust nozzle communicating with the first exchange chamber is provided on the side of the exhaust body.

[0010] Preferably, the air extraction outlet includes an air extraction main pipe and multiple air extraction nozzles connected to the air extraction main pipe. The lower ends of the multiple solenoid valves are each provided with an air extraction port connected to the first exchange chamber. The air extraction nozzles and air extraction ports are sealed and connected in a one-to-one correspondence.

[0011] Preferably, one end of the main exhaust pipe is provided with a second exchange chamber, an exhaust pipe, and an exhaust valve that are connected to the main exhaust pipe. The end of the exhaust pipe and the outer end of the valve core of the exhaust valve are located in the second exchange chamber. When the valve core extends, the outer end of the valve core is sealed and abuts against the end of the exhaust pipe. When the valve core retracts, there is a gap between the outer end of the valve core and the end of the exhaust pipe. The outer wall of the second exchange chamber is provided with an exhaust main interface that is connected to the second exchange chamber.

[0012] Preferably, it also includes a monitoring valve arranged in parallel with the solenoid valve, the air intake of the monitoring valve being sealed to an air intake nozzle of the main air intake pipe; the first exchange chamber communicating with the monitoring valve is provided with an exhaust nozzle and a pressure sensor disposed on the exhaust nozzle.

[0013] Preferably, the main exhaust pipe, the exhaust tube, the second exchange chamber, the exhaust port, and the exhaust nozzle are integrally formed by injection molding.

[0014] Preferably, the exhaust body, main intake pipe, multiple branch pipes, multiple first exchange chambers and exhaust nozzle are integrally formed by injection molding.

[0015] Preferably, the side of the solenoid valve is fixedly connected to the mounting surface of the row base plate by screws.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a combined integrated valve. In practical applications, multiple solenoid valves are combined and fixed on the same row of base plates. During the production and assembly process of the massager, it is only necessary to install and fix the row of base plates to realize the installation and fixation of all solenoid valves. Multiple solenoid valves are arranged in the same direction, and multiple solenoid valves are interconnected with air intakes with higher integration. The number of air pipe connections is reduced, and the assembly process of air pipes and airbags is faster, which greatly simplifies the assembly difficulty of the massager and significantly improves production efficiency.

[0023] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments. The content mentioned in the embodiments is not intended to limit the present invention.

[0024] like Figures 1 to 5As shown, a combined integrated valve includes a row base plate 1 and a plurality of solenoid valves 2 fixedly mounted on the row base plate 1 in a straight array. It also includes an air intake 3 and an air extraction 4. The air intake 3 includes an exhaust body 31, a main air intake pipe 32 opened in the exhaust body 31, a plurality of branch pipes 33 communicating with the side wall of the main air intake pipe 32, and a first exchange chamber 34 disposed at the end of the branch pipes 33. The lower end of one branch pipe 33 corresponds to the valve core 35 of one solenoid valve 2. The end of the branch pipe 33 and the outer end of the valve core 35 are located in the first exchange chamber 34. When the valve core 35 is extended, the outer end of the valve core 35 is sealed and abuts against the end of the branch pipe 33. When the valve core 35 is retracted, there is a gap between the outer end of the valve core 35 and the end of the branch pipe 33. An exhaust nozzle 36 communicating with the first exchange chamber 34 is provided on the side of the exhaust body 31.

[0025] In practical applications, multiple solenoid valves 2 are combined and fixed on the same row base plate 1. During the production and assembly process of the massager, it is only necessary to install and fix the row base plate 1 to achieve the installation and fixation of all solenoid valves 2. Multiple solenoid valves 2 are arranged in the same direction, and multiple solenoid valves 2 are interconnected by an air intake 3 with higher integration. The number of air pipe connections is reduced, and the assembly process of air pipes and airbags is faster, which greatly simplifies the assembly difficulty of the massager and significantly improves production efficiency.

[0026] In this embodiment, the air extraction outlet 4 includes a main air extraction pipe 41 and multiple air extraction nozzles 42 connected to the main air extraction pipe 41. The lower ends of each of the multiple solenoid valves 2 are provided with air extraction ports 43 connected to the first exchange chamber 34. The air extraction nozzles 42 and air extraction ports 43 are sealed together in a one-to-one correspondence. This design not only enables control of multiple air valves in inflation scenarios but also achieves control of multiple air valves in air extraction scenarios through the structural design of the air extraction outlet 4, making it more practical.

[0027] In this embodiment, one end of the main exhaust pipe 41 is provided with a second exchange chamber 44, an exhaust pipe 45, and an exhaust valve 46 that are connected to the main exhaust pipe 41. The end of the exhaust pipe 45 and the outer end of the valve core 35 of the exhaust valve 46 are located in the second exchange chamber 44. When the valve core 35 extends, the outer end of the valve core 35 is sealed and abuts against the end of the exhaust pipe 45. When the valve core 35 retracts, there is a gap between the outer end of the valve core 35 and the end of the exhaust pipe 45. The outer wall of the second exchange chamber 44 is provided with an exhaust main interface 47 that is connected to the second exchange chamber 44.

[0028] like Figure 6 As shown, taking the inflation and deflation of five airbags as an example: Solenoid valve 2 is model STSV361. When de-energized, AC is connected and B is not connected; when energized, AB is connected and C is not connected.

[0029] In positive pressure inflation operation, the main air intake pipe 32 of the air intake outlet 3 is connected to the air pump via an air pipe. Five exhaust nozzles 36 are connected one-to-one with five airbags via air pipes. Solenoid valves 26 and 27 are closed when not energized. When solenoid valves 21 to 25 inflate individually or simultaneously, the corresponding airbags 1 to 5 inflate individually or simultaneously to achieve the massage action of airbags 1 to 5. When airbags 1 to 5 deflate individually or simultaneously, solenoid valve 26 is energized and opened, and the corresponding solenoid valves 21 to 25 open individually or simultaneously, enabling individual inflation and deflation of all airbags. This design is convenient to control and features a simple and reliable structure.

[0030] In a negative pressure vacuuming scenario, the main vacuum pipe 41 of the vacuum outlet 4 is connected to the vacuum pump via an air pipe. The five exhaust nozzles 36 are connected to the five airbags one-to-one via air pipes. When the solenoid valves 2-6 and 2-7 are energized and opened, the corresponding airbags 1 to 5 are inflated separately or simultaneously by controlling the solenoid valves 2-1 to 2-5 to achieve negative pressure operation of the airbags 1 to 5. This is safe, reliable, and suitable for use in negative pressure scenarios.

[0031] In this embodiment, a monitoring valve 21 is also included, which is arranged in parallel with the solenoid valve 2. The air intake 43 of the monitoring valve 21 is sealed to an air intake nozzle 42 of the main air intake pipe 41. The first exchange chamber 34, which is connected to the monitoring valve 21, is provided with an exhaust nozzle 36 and an air pressure sensor 22 disposed on the exhaust nozzle 36. During use in an inflation scenario, the air pressure sensor 22 is designed to monitor the air pressure of the entire inflation pipeline in real time. Combined with the control circuit, inflation is stopped when the air pressure exceeds the safe value, thus avoiding damage to components such as the airbag or injury to the massage user due to excessive inflation pressure, and the safety factor is significantly improved.

[0032] In this embodiment, the main exhaust pipe 41, the exhaust pipe 45, the second exchange chamber 44, the exhaust port 43, and the exhaust nozzle 36 are integrally formed by injection molding. Specifically, the exhaust body 31, the main intake pipe 32, multiple branch pipes 33, multiple first exchange chambers 34, and the exhaust nozzle 36 are integrally formed by injection molding. This integral molding process significantly reduces the manufacturing difficulty of the intake exhaust 3 and the exhaust exhaust 4 without affecting processing accuracy, effectively improving product integrity and production assembly efficiency, and significantly enhancing cost-effectiveness.

[0033] In this embodiment, the side of the solenoid valve 2 is fixedly connected to the mounting surface of the row base plate 1 by screws, which makes assembly convenient and the structure more stable.
