Description

Technical Field

[0001] The utility model relates to the technical field of massage equipment, in particular to an air pressure massager. Background Art

[0002] An air pressure massager is a device that massages human limbs and muscle tissues by inflating and deflating air bags. An air pressure massager is usually equipped with multiple air bags, each of which is inflated by an air pump, and the air circuits of each air bag are controlled by solenoid valves to achieve control over the inflation and deflation of each air bag.

[0003] For example, the Chinese patent application with publication number CN115429660A discloses an exhaust control method and an air pressure massage device, in which the technical solution uses electromagnetic valves corresponding to the air bags to control the inflation and deflation of each air bag, and electromagnetic valves are also configured on the air pump and the air path. The electromagnetic valves corresponding to each air bag are all normally closed electromagnetic valves. During the process of inflation, pumping or deflation of the air pressure massage device, each electromagnetic valve is powered on and opened to connect the air bag with the air path. This patent uses a large number of electromagnetic valves, and the air path control system is relatively complex, resulting in a large size and weight of the controller of the air pressure massager. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a relatively light air pressure massager with a simple structure.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an air pressure massager, including an air pump and a plurality of air bags connected to the air pump, the air bags are connected to the air outlet of the air pump through the main air path channel, the main air path channel is connected to an openable and closable exhaust port, and a multi-way valve assembly is also provided on the main air path channel, the multi-way valve assembly has a plurality of openable and closable charging and discharging ports corresponding to each air bag one by one, and the charging and discharging ports are connected to the corresponding air bags. The utility model adopts a multi-way valve assembly to control the on-off state between each air bag and the main air path channel to realize the switching of the air paths corresponding to different air bags, and integrates the charging and discharging ports corresponding to each air bag one by one into the multi-way valve assembly, so that there is no need to set a solenoid valve for each air bag separately, which effectively reduces the number of solenoid valves used, thereby reducing the overall size and weight of the device, which is conducive to improving the portability of the air pressure massager.

[0006] As an improvement of the above scheme: it also includes an exhaust channel, through which the airbag is connected to the air inlet end of the air pump, and the exhaust channel is connected to an openable and closable air inlet channel. The utility model controls the inflation and deflation action and the air extraction action of the air pressure massager separately by adding an exhaust channel, thereby eliminating the electromagnetic valve used in the prior art to control the switching of the air extraction and inflation and deflation air paths, thereby further reducing the power consumption of the air pressure massager.

[0007] As an improvement of the above scheme: a first one-way valve is provided at the connection point between the airbag and the exhaust channel, and the first one-way valve opens in the direction from the airbag to the exhaust channel. In the utility model, the first one-way valve is used to control the on-off state between each airbag and the exhaust channel, and the opening direction of the first one-way valve is limited. The opening and closing of the first one-way valve is controlled by the air pressure difference on both sides of the first one-way valve. When the air pressure massager performs massage work normally, the airbag can be pressurized, and the gas in the airbag can be automatically forced to enter the exhaust channel during the process of pumping and deflation to prevent the gas from flowing back into the airbag.

[0008] As an improvement of the above scheme: the air inlet end and the air outlet end of the air pump are connected, and a second one-way valve is arranged between the air inlet end and the air outlet end, and the second one-way valve opens in the direction from the air inlet end to the air outlet end. The utility model connects the air inlet end and the air outlet end of the air pump separately through a pipeline, so that the exhaust channel and the main air channel are directly connected, and the second one-way valve is used to control the on-off of the pipeline and limit the opening direction of the second one-way valve, so that the air can be deflated directly without passing through the air pump during the deflation of the air pressure massager or in the event of abnormal power failure.

[0009] As an improvement of the above scheme: an air intake solenoid valve is provided at the connection point between the exhaust channel and the air intake channel, and the air intake solenoid valve is a three-way solenoid valve, and the three interfaces of the air intake solenoid valve are respectively connected to the exhaust channel, the air intake channel and the air intake end of the air pump. The utility model switches the air path corresponding to the air pump intake and the air bag exhaust by setting the air intake solenoid valve, effectively reducing the number of solenoid valves used and reducing the power consumption of the air pressure massager.

[0010] As an improvement of the above scheme: when the air intake solenoid valve is in the energized state, the air intake passage is connected to the air intake end of the air pump; when the air intake solenoid valve is in the de-energized state, the exhaust passage is connected to the air intake end of the air pump. The utility model limits the type of solenoid valve used by the air intake solenoid valve, so that the air intake solenoid needs to be energized to maintain the connection of the air intake air path only when the air pump is inflating the airbag. At other times, the air intake solenoid valve can remain in the de-energized state, which can effectively reduce the power consumption of the air intake solenoid valve.

[0011] As an improvement of the above scheme: the exhaust port is provided with an exhaust solenoid valve for controlling the opening and closing of the exhaust port. The utility model switches the air path corresponding to the inflation and deflation of the airbag through the exhaust solenoid valve, effectively reducing the number of solenoid valves used and reducing the power consumption of the air pressure massager.

[0012] As an improvement of the above scheme: the exhaust solenoid valve is a normally open solenoid valve; when the exhaust solenoid valve is in a power-off state, the main air path is connected to the external environment through the exhaust port. The utility model limits the type of solenoid valve used in the exhaust solenoid valve, so that the air path of the air pressure massager can be connected to the external environment for automatic deflation when the power is off, which can effectively avoid the situation where the airbag cannot be deflated due to power failure.

[0013] As an improvement of the above solution: it also includes a pressure sensor for monitoring the inflation pressure of the airbag and controlling the inflation and deflation of the airbag according to the monitored inflation pressure. The pressure sensor is arranged on the main air passage between the air pump and the exhaust port. The utility model monitors the inflation pressure by arranging a pressure sensor to determine whether the inflation pressure of the airbag reaches the set value, so as to facilitate the control of the airbag pressure maintenance.

[0014] As an improvement on the above scheme: the multi-way valve assembly consists of a stepper motor, a transmission member, a valve core and a valve body; the stepper motor is connected to the valve core through the transmission member, the valve core is rotatably arranged in the valve body, the valve core is connected to the main channel of the gas path, and multiple charging and discharging ports are arranged on the valve body in a ring-shaped manner; the valve core rotates under the drive of the stepper motor to connect the main channel of the gas path with different charging and discharging ports.

[0015] The beneficial effect of the utility model is that the utility model adopts a multi-way valve assembly to control the on-off state between each air bag and the main air path channel to realize the switching of the air paths corresponding to different air bags, and integrates the charging and discharging ports corresponding to each air bag into the multi-way valve assembly. There is no need to set a solenoid valve separately for each air bag, which can effectively save the space occupied by the solenoid valve inside the air pressure massager, thereby reducing the overall volume size of the air pressure massager and reducing the overall weight of the air pressure massager, which is conducive to promoting the lightweight and miniaturization development of the air pressure massager.

DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0025] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "front", "rear", "left", "right", "up", "down", and "inside" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of description. They do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0026] like Figure 1 As shown, the air pressure massager disclosed in the utility model includes an air pump 100 and a plurality of air bags 200. The air pump 100 has an air inlet end and an air outlet end. The air outlet end of the air pump 100 is connected to each air bag 200 through the main air channel 300. The working air of the air pump 100 is transmitted to each air bag 200 through the main air channel 300 to restart the air bag 200. The main air channel 300 is connected to an openable and closable exhaust port 400, and the exhaust port 400 is connected to the external environment; during the deflation process of the air pressure massager, the exhaust port 400 is opened to connect the main air channel 300 with the external environment, and the air bag 200 is deflated and discharged into the external environment through the exhaust port 400.

[0027] In order to reduce power consumption, the utility model improves the prior art solution of using multiple solenoid valves to perform one-to-one control on the airbags 200, and replaces the multiple solenoid valves by setting a multi-way valve assembly 900, and uses the multi-way valve assembly 900 to realize the switching of the connection state between the multiple airbags 200 and the main airway channel 300. The multi-way valve assembly 900 has multiple charging and discharging ports, which are in a one-to-one correspondence with the airbags 200 and are connected to the corresponding airbags 200, and the connection or disconnection of the airway between the corresponding airbag 200 and the main airway channel 300 is realized by controlling the opening and closing of the charging and discharging ports; when one of the airbags needs to be inflated or deflated, the charging and discharging port corresponding to the airbag is opened through the multi-way valve assembly 900.

[0028] Specifically, Figure 6 and Figure 7 As shown, the multi-way valve assembly 900 used in the present invention adopts a multi-way valve composed of a stepper motor 910, a transmission member 920, a valve core 930 and a valve body 940. The stepper motor 910 is fixedly connected to the valve body 940, the transmission member 920 and the valve core 930 are installed inside the valve body 940, the transmission member 920 is fixedly connected to the output end of the stepper motor 910, the valve core 930 is fixedly connected to the transmission member 920, and the stepper motor 910 drives the transmission member 920 to rotate when working, and then drives the valve core 930 to rotate synchronously. The charging and discharging ports of the multi-way valve assembly 900 are arranged in a ring-shaped interval on the valve body 940 using a joint structure. The valve core 930 has a passage inside that is connected to the main air channel 300, and this passage can be aligned and connected with different charging and discharging ports as the valve core 930 rotates. When this passage is aligned with one of the charging and discharging ports, the other charging and discharging ports are blocked and closed by other parts of the valve core 930, thereby realizing the switching of the air channel between the main air channel 300 and different airbags 200.

[0029] like Figure 1 As shown, in the utility model, an exhaust channel 500 is separately provided to realize the extraction of air from the airbag 200 and the automatic deflation of the airbag 200. The exhaust channel 500 is connected to each airbag 200, and at the same time, the exhaust channel 500 is connected to the air inlet end of the air pump 100. The exhaust channel 500 is also connected to an openable and closable air inlet 600, and the air inlet 600 is connected to the external environment; the switching of the air inlet path and the exhaust path of the air pump 100 is realized by controlling the opening and closing of the air inlet 600. When the air inlet 600 is connected to the air pump 100 and the exhaust channel 500 is disconnected from the air pump 100, the air inlet path is connected; when the air inlet 600 is disconnected from the air pump 100 and the exhaust channel 500 is connected to the air pump 100, the exhaust path is connected.

[0030] Furthermore, in the present invention, the connection state between each airbag 200 and the exhaust channel 500 is controlled by setting a first one-way valve 710. Figure 1As shown, a first one-way valve 710 is provided between each airbag 200 and the exhaust channel 500, and the first one-way valve 710 opens in the direction from the airbag 200 to the exhaust channel 500; the first one-way valve 710 remains closed to prevent gas from flowing back into the airbag, maintains the air pressure in the airbag 200 at a preset air pressure value, and realizes the pressure maintenance of the airbag 200. Only when the air pressure in the airbag 200 is greater than the air pressure in the exhaust channel 500, the first one-way valve 710 will open to release the pressure of the airbag 200. In addition, during the process of air pumping and automatic deflation of the air pressure massager, due to the reduction of the air pressure in the exhaust channel 500, the gas in the airbag 200 can push open the first one-way valve 710 and automatically enter the exhaust channel 500, and continue to pump or exhaust.

[0031] Further, such as Figure 1 As shown, the air inlet end and the air outlet end of the air pump 100 in the utility model are directly connected, and a second one-way valve 720 is provided between the air inlet end and the air outlet end, and the second one-way valve 720 opens in the direction from the air inlet end to the air outlet end. The utility model connects the air inlet end and the air outlet end of the air pump 100 separately, so that the exhaust channel 500 and the main air channel 300 are directly connected and connected, and the second one-way valve 720 is used to control the connection and disconnection between the air inlet end and the air outlet end, and to limit the opening direction of the second one-way valve 720, so that the air can be directly deflated without passing through the air pump 100 during the deflation process of the air pressure massager or in the event of abnormal power failure.

[0032] Specifically, the opening and closing of the air inlet 600 is controlled by setting an air intake solenoid valve 810 in the utility model. The air intake solenoid valve 810 adopts a three-way solenoid valve, and the three interfaces of the air intake solenoid valve 810 are respectively connected to the exhaust channel 500, the air intake port 600 and the air intake end of the air pump 100; when the air intake solenoid valve 810 is in the power-on state, the air intake port 600 is connected to the air intake end of the air pump 100; when the air intake solenoid valve 810 is in the power-off state, the exhaust channel 500 is connected to the air intake end of the air pump 100. In the utility model, the opening and closing of the exhaust port 400 is controlled by setting an exhaust solenoid valve 820, and the two interfaces of the exhaust solenoid valve 820 are respectively connected to the main air channel 300 and the exhaust port 400; the exhaust solenoid valve 820 is a normally open solenoid valve, and when the exhaust solenoid valve 820 is in the power-off state, the main air channel 300 is connected to the external environment. Compared with the prior art that uses multiple solenoid valves to control the opening and closing of various air passages, the utility model only provides two solenoid valves, namely, an air intake solenoid valve 810 and an exhaust solenoid valve 820, which greatly reduces the number of solenoid valves used, thereby effectively reducing the power consumption caused by the use of solenoid valves. In addition, the utility model adds a power-off deflation function to the air pressure massager by providing the air intake solenoid valve 810 and the exhaust solenoid valve 820. When the air pressure massager is abnormally powered off, the air intake solenoid valve 810 is powered off to connect the exhaust passage 500 with the main air passage 300, and the exhaust solenoid valve 820 is powered off to connect the main air passage 300 with the external environment, thereby forming an air passage connecting the airbag 200 with the external environment, so that the airbag 200 can be automatically deflated when the air pressure massager is abnormally powered off, so as to avoid the situation where the airbag 200 remains in an inflated state and is not easy to fold.

[0033] Further, such as Figure 1 As shown, the utility model is also provided with a pressure sensor 310 to monitor the inflation pressure, and the pressure sensor 310 is arranged on the main gas path 300 between the air pump 100 and the exhaust port 400. When the pressure sensor 310 monitors that the inflation pressure in the airbag 200 reaches a preset pressure value, the inflation action of the airbag 200 can be stopped.

[0034] like Figure 2As shown, the air pressure massager disclosed in the utility model performs the inflation work. The air inlet solenoid valve 810 is energized, the air inlet 600 is connected to the air inlet end of the air pump 100, and the air pump 100 works to draw air from the external environment into the air inlet 600, and then enters the main air path channel 300 through the air pump 100. The exhaust solenoid valve 820 is energized, the main air path channel 300 is isolated from the external environment, and the multi-way valve assembly 900 connects the main air path channel 300 with the airbag 200 to be inflated, and the airbag 200 is continuously inflated until the pressure sensor 310 detects that the air pressure value reaches a preset value, and then the air pump 100 stops inflating, and the multi-way valve assembly 900 closes the charging and discharging port of the inflated airbag 200 to maintain the pressure in the airbag 200, so that the air pressure massager has the function of inflation and pressure maintenance when working.

[0035] like Figure 3 As shown, the air pressure massager disclosed in the utility model performs deflation. The exhaust solenoid valve 820 is powered off, the main air path 300 is connected to the external environment, and the multi-way valve assembly 900 connects the main air path 300 with the airbag 200 to be deflated. The gas in the airbag 200 flows into the main air path 300 due to the pressure, and then passes through the exhaust solenoid valve 820 and is discharged to the external environment through the exhaust port 400. In this process, the air pressure massager deflates more thoroughly, and the user can feel a more obvious pressure change.

[0036] like Figure 4 As shown, the air pressure massager disclosed in the utility model performs the air extraction work. The air inlet solenoid valve 810 is powered off, the exhaust channel 500 is connected to the air inlet end of the air pump 100, and the air pump 100 extracts the gas in the exhaust channel 500 into the main air channel 300. The gas in the exhaust channel 500 is reduced and the air pressure is reduced. The gas in the airbag 200 pushes the first one-way valve 710 and continues to enter the exhaust channel 500; the exhaust solenoid valve 820 is powered off, the main air channel 300 is connected to the external environment, and the gas extracted by the air pump 100 passes through the exhaust solenoid valve 820 and is discharged into the external environment through the exhaust port 400. After using the air pressure massager, the user can force the airbag 200 to quickly release the pressure through the air extraction operation, so that the air pressure massager can quickly return to a foldable state.

[0037] like Figure 5As shown, the air pressure massager disclosed in the utility model automatically deflates when the power is turned off. At this time, the air pump 100, the air inlet solenoid valve 810 and the exhaust solenoid valve 820 are all in the power-off state. The exhaust solenoid valve 820 is powered off to connect the main air channel 300 with the external environment. The gas in the main air channel 300 is discharged to the external environment through the exhaust port 400. The air pressure in the main air channel 300 is reduced. The gas in the exhaust channel 500 pushes the second one-way valve 720 after passing through the power-off air inlet solenoid valve 810 and flows into the main air channel 300. At this time, the air pressure in the exhaust channel 500 also continues to decrease. The gas in the airbag 200 pushes the first one-way valve 710 and continues to enter the exhaust channel 500, and flows through the main air channel 300 and the exhaust port 400 in sequence before being discharged. Therefore, after the use of the air pressure massager is over or after the working time set by the air pressure massager expires, even if the user does not operate, the air pressure massager will automatically deflate and slowly return to the foldable state. In addition, if the power of the air pressure massager is exhausted and not replenished, or there is an abnormal power outage such as a sudden power outage due to a malfunction, the air pressure massager can still slowly exhaust the gas to avoid remaining inflated.
