Description

Technical Field

[0001] The present invention belongs to the technical field of massage equipment, and in particular relates to pneumatic massage equipment, and more particularly to a constant-pressure foot massager and a method of using the same. Background Art

[0002] The constant-pressure foot massager generates controllable air pressure from an air source, delivering it to the foot massage bladders. This dynamic adjustment of air pressure massages acupuncture points on the soles of the feet, relaxes muscles, and promotes blood circulation. The system maintains a constant pressure within the bladders through a pressure feedback mechanism, ensuring a consistent and stable massage effect.

[0003] In the related art, in order to improve the convenience of assembling the constant pressure foot massager, the interface and the hose are connected by plugging. After repeated use, the connection between the hose and the interface is prone to loosening and air leakage, which causes the airbag to be unable to achieve constant pressure during massage and unable to reach the set pressure for massage, affecting the massage effect.

[0004] Therefore, how to prevent the loose interface from affecting the massage effect of the foot massager is a technical problem that needs to be solved urgently.

[0005] It should be noted that the above information disclosed in this background technology section is only used to understand the background technology of the present application concept, and therefore, the above description is not considered to constitute information of the prior art.

DETAILED DESCRIPTION

[0067] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0068] In this document, when it is mentioned that a first component is located on a second component, this may mean that the first component may be directly formed on the second component, or that a third component may be interposed between the first component and the second component. In addition, in the drawings, the thickness of components may be exaggerated or reduced in order to effectively describe technical content.

[0069] As used herein, when an element or layer is referred to as being "located on," "engaged to," "connected to," "attached to," or "coupled to" another element or layer, it may be directly located on, engaged, connected, attached to, or coupled to the other element or layer, or there may be intervening elements or layers. Conversely, when an element is referred to as being "directly on," "directly engaged to," "directly connected to," "directly attached to," or "directly coupled to" another element or layer, there may be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted in a similar manner (e.g., "between" versus "directly between," "adjacent" versus "directly adjacent," etc.). As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0070] Herein, example embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. As used herein, expressions such as "at least one of..." when following a list of elements modify the entire list of elements, rather than modifying individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or all of a, b, and c.

[0071] The terms used herein are only used to describe specific exemplary configurations and are not intended to be limiting. As used herein, the singular articles "a", "an" and "the" may also be intended to include plural forms, unless otherwise clearly indicated herein. The terms "comprise", "include" and "have" are inclusive and therefore specify the presence of features, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components and / or combinations thereof. The method steps, processes and operations described herein should not be interpreted as necessarily requiring them to be performed in the particular order discussed or shown, unless specifically identified as an execution order. Additional or alternative steps may be adopted.

[0072] As used herein, the phrases "in one embodiment," "according to one embodiment," "in some embodiments," and the like generally refer to the fact that the particular feature, structure, or characteristic following the phrase may be included in at least one embodiment of the present disclosure. Thus, a particular feature, structure, or characteristic may be included in more than one embodiment of the present disclosure, such that these phrases do not necessarily refer to the same embodiment. As used herein, the terms "example," "exemplary," and the like are used to "serve as an example, instance, or illustration." Any implementation, aspect, or design described herein as "example" or "exemplary" is not necessarily to be construed as preferred or advantageous over other implementations, aspects, or designs. Instead, the use of the terms "example," "exemplary," and the like is intended to present concepts in a concrete manner.

[0073] Research has found that in order to facilitate storage, the constant pressure foot massagers in related technologies generally do not use mechanical plug-in interfaces (such as threaded screw structures), but instead use a hose and connector structure that is easy to disassemble for quick installation. After the hose is inserted into the interface, as the number of plug-in and unplugging increases and during repeated inflation and deflation, the displacement of the connection between the hose and the interface due to material deformation will cause air leakage. In severe cases, the hose will fall off, directly affecting the massage effect of the foot massage airbag.

[0074] Based on the above research, an embodiment of the present disclosure provides a constant pressure foot massager and a method of use thereof. The air pressure generated when the air source 200 is inflated clamps the cavity 410 and the annular groove 310 to achieve mechanical locking, thereby improving the stability of the connection between the hose and the interface 300 and enhancing the massage effect.

[0075] The defects in the above solutions are the results obtained by the inventors after practice and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure in this article should be the contributions made by the inventors to the present disclosure during the disclosure process.

[0076] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0077] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0078] See also Figure 1 and Figure 2 At least one embodiment provides a constant-pressure foot massager, comprising: a massager housing 100; an air source 200, which is disposed in the massager housing 100; a plurality of interfaces 300, which are disposed on the massager housing 100 and communicated with the air source 200; and foot massage airbags (not shown), which are communicated with the interfaces 300 via a hose (not shown).

[0079] Please note that Figure 5 The air source 200 includes an air pump 210, a solenoid valve 220 and a connecting pipe 230. The solenoid valve 220 controls the on-off connection between the air pump 210 and each interface 300, thereby achieving precise control of the foot massage airbag pressure and improving the massage effect.

[0080] See also Figure 2 and Figure 3 , wherein an annular groove 310 is provided on the outer wall of the interface 300; an air channel 320 is opened on the tube wall of the interface 300 for connecting the inner tube of the interface 300 with the outside of the interface 300; a connecting pipe 400 is provided at the end of the hose to be docked with the interface 300; a cavity 410 is provided in the wall of the connecting pipe 400, and the wall of the cavity 410 is made of elastic material; when the connecting pipe 400 is docked with the interface 300, the cavity 410 covers the annular groove 310, and the cavity 410 is opened with a through hole 420 connected to the air channel 320. When the interface 300 is ventilated, the gas enters the cavity 410 from the air channel 320 (the gas flow direction is as shown in FIG. Figure 2 As shown in FIG. 5(F), the cavity 410 is expanded and engaged with the annular groove 310, thereby connecting the connecting pipe 400 to the interface 300.

[0081] Through the cooperation between the cavity 410 and the annular groove 310, when the gas source 200 is started, the air pressure is used to drive the cavity 410 to deform and form a mechanical lock with the annular groove 310, thereby realizing the dynamic self-locking function of the interface 300 and the hose, so that the connection strength is positively correlated with the pressure of the gas source 200, and a stable connection can still be maintained under the working conditions of the inflation and deflation pressure fluctuations of the foot massage airbag, thereby reducing the leakage rate of the interface 300, thereby improving the internal pressure control accuracy of the foot massage airbag, and then ensuring the accuracy of the pressure during massage, thereby enhancing the massage effect.

[0082] See also Figure 2 and Figure 3 The interface 300 is L-shaped, and includes a vertical tube 330 and a horizontal tube 340 that are connected; the hose is sleeved on the horizontal tube 340; the vertical tube 330 passes through the massager housing 100 and is connected to the air source 200; the vertical tube 330 is provided with an L-shaped slide groove 331; the connecting tube 400 is provided with a slider 430 at the fitting position of the L-shaped slide groove 331, and the connecting tube 400 is connected to the horizontal tube 340 through the slider 430 and the L-shaped slide groove 331.

[0083] Through the cooperation of the slider 430 and the L-shaped groove 331, the connection between the connecting pipe 400 and the interface 300 is sealed, so that a stable air path is formed between the airway 320 and the cavity 410, thereby improving the accuracy of pressure control in the foot massage airbag.

[0084] See also Figure 4 The L-shaped groove 331 is a slot 331a arranged along the radial direction of the vertical tube 330, and an arc-shaped groove 331b is arranged along the circumference of the vertical tube 330 gradually approaching the axis; after the slider 430 is aligned with the slot 331a and the connecting tube 400 is inserted into the horizontal tube 340, the connecting tube 400 is rotated by external force to make the slider 430 slide along the arc-shaped groove 331b to clamp the connecting tube 400 to the interface 300.

[0085] Through the composite guide formed by the arc-shaped slide groove 331b and the slot 331a, the slider 430 is first axially inserted into the slot 331a to complete the initial positioning, and then the connecting tube 400 is rotated to make the slider 430 slide into the arc-shaped slide groove 331b to achieve secondary locking, further ensuring the formation of a stable air path between the airway 320 and the cavity 410, improving the accuracy of pressure control in the foot massage airbag, and thus improving the massage effect.

[0086] See also Figure 2 and Figure 3A circular air groove 332 is provided at the connection between the horizontal tube 340 and the vertical tube 330; after the connecting tube 400 is inserted into the horizontal tube 340, it is stuck in the circular air groove 332; the cavity 410 is connected to the circular air groove 332 through the through hole 420; the air duct 320 is connected to the circular air groove 332.

[0087] Specifically, a baffle 333 is provided in the circular air groove 332 ; air holes 333 a are provided at positions of the baffle 333 corresponding to the through hole 420 .

[0088] When the air hole 333a is connected to the through hole 420, the gas enters the middle cavity 410 from the air channel 320, causing the cavity 410 to undergo elastic deformation, completing the snap connection with the circular slot, that is, locking the connecting tube 400 and the interface 300; then the connecting tube 400 is rotated to misalign the air hole 333a and the through hole 420, and the cavity 410 is sealed. At this time, the gas source 200 stops supplying gas, and the airtightness of the cavity 410 is checked to ensure the stability of the connection between the connecting tube 400 and the interface 300.

[0089] Condensed water is easily accumulated at the connection point between the hose and the interface 300 in the related art, thereby accelerating the aging of the hose.

[0090] See also Figure 2 and Figure 3 In order to avoid such problems, in a preferred embodiment, the inner tube of the interface 300 is provided with a water tank 341 connected to the airway 320; when the foot massage airbag is deflated, the condensed water in the hose is blown into the water tank 341.

[0091] By setting up a water storage tank 341, condensed water is collected. After the massage is completed, the connecting tube 400 is partially pulled out by external force, so that the airway 320 is connected to the outside of the interface 300. When the foot massage airbag is exhausted, the liquid is discharged from the water storage tank 341 along the airway 320 to the outside of the interface 300. At the same time, the interface 300 is dried by the airflow, reducing the impact on the next time the connecting tube 400 is inserted into the interface 300.

[0092] See also Figure 2 There are multiple air passages 320 , and the multiple air passages 320 are arranged to be closed along the axial direction of the interface 300 .

[0093] The inclined air passage 320 can, on the one hand, reduce the resistance of the gas when entering the air passage 320 , and on the other hand, facilitate the discharge of the liquid in the water storage tank 341 .

[0094] See also Figure 2 and Figure 3In a preferred embodiment, the interface 300 is provided with a circular air groove 332; after the connecting pipe 400 is inserted into the horizontal pipe 340, it is stuck in the circular air groove 332; the cavity 410 is connected with the circular air groove 332 through the through hole 420; the air channel 320 is connected with the circular air groove 332; a baffle 333 is provided in the circular air groove 332; air holes 333a are provided at the corresponding positions of the baffle 333 and the through hole 420.

[0095] When the air hole 333a is connected to the through hole 420, the gas enters the middle cavity 410 from the air channel 320, causing the cavity 410 to undergo elastic deformation, completing the snap connection with the circular slot, that is, locking the connecting tube 400 and the interface 300; then the connecting tube 400 is rotated to misalign the air hole 333a and the through hole 420, and the cavity 410 is sealed. At this time, the gas source 200 stops supplying gas, and the airtightness of the cavity 410 is checked to ensure the stability of the connection between the connecting tube 400 and the interface 300.

[0096] See also Figure 6 A method for using the constant pressure foot massager as described above, the method comprising:

[0097] S110, connecting the foot massage airbag to the interface 300 through a hose;

[0098] S130, turning on the air source 200, pre-inflating the foot massage airbag through the interface 300 and the hose;

[0099] S140, the gas enters the cavity 410 from the airway 320, causing the cavity 410 to expand and then engage with the annular groove 310, connecting the connecting pipe 400 to the interface 300, and completing the installation of the constant pressure foot massager.

[0100] Before performing the steps of opening the air source 200 and pre-inflating the foot massage airbag through the interface 300 and the hose, the method of use further includes:

[0101] S120 : Rotate the connecting pipe 400 to align the through hole 420 with the air hole 333 a .

[0102] After the gas enters the cavity 410 from the air passage 320, causing the cavity 410 to expand and engage with the annular groove 310, the connecting tube 400 is connected to the interface 300, and the constant pressure foot massager is installed, the method of use further includes:

[0103] S150: Rotate the connecting pipe 400 so that the through hole 420 and the air hole 333a are offset.

Through the cooperation between the cavity 410 and the annular groove 310, when the gas source 200 is started, the air pressure is used to drive the cavity 410 to deform and form a mechanical lock with the annular groove 310, thereby realizing the dynamic self-locking function of the interface 300 and the hose, so that the connection strength is positively correlated with the pressure of the gas source 200, and a stable connection can still be maintained under the working conditions of the inflation and deflation pressure fluctuations of the foot massage airbag, thereby reducing the leakage rate of the interface 300, thereby improving the internal pressure control accuracy of the foot massage airbag, and then ensuring the accuracy of the pressure during massage, thereby enhancing the massage effect.
