Description

Personalized insole capable of being rapidly molded and manufacturing method thereof

Technical Field

The invention relates to an insole structure, in particular to a personalized insole which can be quickly formed according to the individual foot bottom three-dimensional configuration and is internally provided with a negative pressure auxiliary assembly.

Background

When people wear shoes, the insoles are placed in the shoes, so that the shock absorption and buffering effects of the insoles are utilized to relieve sole pain and other diseases caused by long-time standing or walking, and meanwhile, the feet can be provided with better comfort. Generally, the sole of the foot should normally have a significantly higher arch (i.e., the concave arc on the medial side of the foot), and the talus (talus) and calcaneus (calceneus) should be collinear and perpendicular to the ground. However, with the relationship of nature or nature, the spatial configuration of the sole of each person may vary, for example, some people with Flat feet (Flat Foot) may have a low or no arch; alternatively, when the child stands prematurely or is in an incorrect posture for a long period of time, a Pronation of the foot may be prone to occur.

The existing insoles are usually produced in large quantities in the same shape instead of aiming at the sole condition of each person, so that a user often selects a softer insole when purchasing the insoles, and thus, when the user steps on the insoles, the insoles have larger deformation and bring more comfortable feeling to people. However, softer insoles often have insufficient support, and therefore, over time, the plantar muscles tend to tighten and the poor fascia of the lower extremities tends to be aggravated by those with flat feet or high arches. It follows that in selecting insoles, it is still preferable to select insoles which are supportive to the sole of the foot.

While it is clear that the stereoscopic configurations of the sole of each person are different, the mass-produced insoles are not practical for each person, but the customized insoles usually require several weeks and more time for correction, which is relatively cumbersome, and requires a lot of special equipment and tools, which is not practical for the general public. In view of the above, the inventor has devised a corrective insole capable of being quickly tailored, and briefly described later, referring to fig. 1A, the corrective insole 10 includes an inner covering layer 11, a plurality of granules 12 and an outer covering layer 13, wherein the inner covering layer 11 is made of an air-permeable material and is filled with the granules 12, and then the inner covering layer 11 together with the granules 12 can be placed into the air-impermeable outer covering layer 13, and the outer covering layer 13 is provided with an air passage 131, and the air passage 131 is communicated with the inside and the outside of the outer covering layer 13.

Referring to fig. 1A, in the manufacturing process, the rectification insole 10 can be first placed in a shaping groove 151 of a supporting fixture 15 (e.g., a shoe mold), and then a professional (e.g., a rehabilitation engineer) can assist the user to adjust the position of the foot, so that the foot can step on the top surface of the rectification insole 10 in a correct posture (i.e., a posture required for rectification), and the particles 12 can be shaped (formed) into a desired rectification state; after the shaping process is completed, a professional can connect the air channels with a special vacuum device (such as a vacuum pump, a valve, a vacuum gauge, a pipe, a connector 8230; etc.) and perform a vacuum operation on the corrective insole 10 to shape the particles 12 in a state of being tightly attached to each other and being unable to move further, and then hermetically seal the air channels 131 to shape the corrective insole 10 (as shown in fig. 1B).

Although the aforementioned orthotic insole 10 conceived by the inventor is much shorter than the conventional orthotic insole in terms of personalized manufacturing time (less than 10 minutes) and price, it is still not enough to be widely used by the general public, the main reason is that the orthotic insole 10 not only requires special vacuum-pumping and shaping auxiliary equipment (such as shoe mold table, shaking table, sealing machine 8230; etc.), but also requires professional assistance, which is not provided by the general user, so that the user in need can only purchase the insole in a special place, such as foot orthotic place or insole shoplifter, etc. In addition, in order to provide the corrective insole 10 with a good corrective power, a large number of particles 12 are required to be placed therein to be shaped to a desired state for the correction, which also results in the overall production cost of the corrective insole 10 being higher than that of a general insole.

For the general public, the insole used by the general public is not necessarily required to be strict to the nature of correction, but is mainly comfortable and daily health care, so that under the aforementioned problems (such as the need of special equipment, exclusive shops/places, professional services and higher cost), the corrective insole 10 will greatly reduce the purchase and use will of the general public, and therefore, how to effectively solve the aforementioned problems to provide a more suitable product for the general public becomes an important subject of the present invention.

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the invention relating to "personalized insole capable of rapid prototyping and manufacturing method thereof" disclosed in the present invention are further described in detail below with reference to the accompanying drawings. The advantages and effects of the present invention will be apparent to those skilled in the art from the disclosure of the present specification. The invention is capable of other and different embodiments and its several details are capable of modification and various other changes, which can be made in various details within the specification and without departing from the spirit and scope of the invention. It should be noted that the drawings of the present invention are for illustrative purposes only and are not drawn to scale. Furthermore, the meaning of "a", "an", and "the" of the present invention includes a plurality, unless the context clearly indicates or defines otherwise. The following embodiments will further explain the technical matters related to the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.

It will be understood that, although the terms first, second, etc. may be used herein to describe various components or signals, these components should not be limited by these terms. These terms are used primarily to distinguish one element from another. In addition, directional terms such as "upper", "lower", "front", "rear", "left", "right", and the like, which refer to the embodiments, are directions only referring to the drawings. Accordingly, the directional terminology used is intended to be in the nature of words of description rather than of limitation. Further, as used herein, the term "or" should be taken to include any one or combination of the associated listed items, as the case may be.

The invention relates to a personalized insole capable of being quickly formed and a manufacturing method thereof, wherein the personalized insole is mainly used as a general adaptive pressure-relief type insole, special auxiliary tools (such as special vacuum pumping equipment and the like) are not required to be additionally used, and a user can easily manufacture the personalized insole matched with the self sole three-dimensional configuration. Referring to fig. 2, in a first embodiment, the personalized insole 2 includes an outer covering layer 21, a plurality of granules 22, at least one negative pressure auxiliary component 23 and at least one opening and closing component 24, wherein the outer covering layer 21 is made of an air-impermeable material or an air-impermeable structure, the periphery of which is hermetically sealed to form a first accommodating space therein, and the planar configuration of the outer covering layer 21 can match with the overall planar configuration of the sole of the foot (as shown in fig. 3A), and at least a partial area of the top surface of the outer covering layer is made of an elastic or flexible air-impermeable material or structure to form a planar configuration conforming to the sole of the foot in the following process, but not limited thereto, and in other embodiments of the present invention, the planar configuration of the outer covering layer 21 can also match with the planar configuration of a partial portion of the sole of the foot (e.g., a partial portion corresponding to the metatarsals, the midfoot bone or the heel bone), which is described in advance.

Referring to fig. 2 again, the outer cladding 21 can be provided with at least one air channel 211, and the air channel 211 is connected to the inside and the outside of the outer cladding 21, so that the air in the first accommodating space can flow out of the outer cladding 21 through the air channel 211. In addition, in the first embodiment, the particles 22 can be directly packed into the outer cladding 21 so that the outer cladding 21 takes a predetermined thickness and is maintained in a soft state, and the particles 22 can move within the outer cladding 21. In addition, the personalized insole 2 is further provided with an opening and closing component 24, the opening and closing component 24 is air-tightly installed on the outer covering layer 21 at a position corresponding to the air channel 211, for example, can be installed inside the air channel 211, or inside and/or outside the outer covering layer 21, in the first embodiment, as shown in fig. 2, the opening and closing component 24 is located inside the outer covering layer 21. In addition, the opening and closing assembly 24 can make the air channel 211 in a one-way outward exhaust state, or can make the air channel 211 in a two-way conduction state or in a two-way non-conduction state. In addition, in order to prevent the particles 22 from flowing out of the outer cladding 21 through the air channel 211, the open/close component 24 can also add a blocking structure (e.g., a filter net) to have the effect of blocking the particles 22 from flowing out through the air channel 211.

Referring back to fig. 2 and 3A, to avoid overcomplicating the drawings, the particles 22 are omitted from fig. 3A. The negative pressure auxiliary assembly 23 can be located in the outer cladding 21, and the location and number of the negative pressure auxiliary assembly can be determined according to actual requirements, as shown in fig. 3A, there can be only a single negative pressure auxiliary assembly 23; alternatively, as shown in fig. 3B, there can be a plurality of negative pressure auxiliary assemblies 23; also, the sub-atmospheric pressure sub-assembly 23 can be generally located within the outer cladding 21 adjacent to the bottom surface, and the top surface can be stacked with the particles 22. The negative pressure auxiliary assembly 23 is characterized in that when it is pressed by external force and deformed (reduced), it will generate a restoring force, and when the external pressure disappears, it can restore itself to the original state, and the negative pressure auxiliary assembly 23 itself has at least one air-containing space 26, when it is pressed by external force and deformed (reduced), it will discharge the air in the air-containing space 26, otherwise, when the external force disappears, its own restoring force will force it to suck external air into each air-containing space 26. For example, in the first embodiment, the negative pressure auxiliary member 23 can be an open porous elastic material (e.g., foam), and the collective pores or pores thereon are the air-containing space 26. The term "open" refers to the fact that the air-containing space 26 directly communicates with the external space of the negative pressure auxiliary assembly 23, and the "open" in the following embodiments is also the same as the above definition.

Referring to fig. 2 and 3A, when the sole of a foot of a user steps on or applies pressure to the top surface of the outer coating 21 (wholly or partially), the particles 22 are shaped (i.e., formed) along with the three-dimensional configuration of the sole of the foot, and the air in the outer coating 21 is discharged out of the outer coating 21 through the air channel 211 due to the pressure applied by the sole of the foot; in addition, the negative pressure auxiliary component 23 will also be affected by the aforementioned pressure to reduce its occupied volume, and the air in the air containing space 26 will also be exhausted out of the negative pressure auxiliary component 23 and then out of the outer cladding 21 through the air channel 211. Moreover, when the user seals the air channel 211 by the opening/closing element 24, so that air cannot flow into the outer covering layer 21 from the atmosphere side, and removes the pressure applied by the sole of the foot, the negative pressure auxiliary element 23 will expand due to its own restoring force and absorb the residual air among the particles 22 in a relatively large proportion, so as to form a negative pressure in the outer covering layer 21, so that the particles 22 are shaped in a state of being tightly attached to each other and not easily displaced, thereby obtaining the personalized insole 2 (as shown in fig. 4).

For the user, the formation of the personalized insole 2 is mainly completed through two stages of "forming" and "shaping". In the "forming" stage, the user can place the sole of the foot on the outer coating 21 and apply pressure, this stage allowing only the air inside the outer coating 21 to be discharged outside the outer coating 21 in one direction through the air passage 211; in the "setting" phase, the user's foot will leave the outer coating 21 to remove the pressure exerted by it, this phase not allowing the air outside the outer coating 21 to flow in one direction through the air passage 211 to the inside of the outer coating 21. As mentioned above, the opening and closing assembly 24 should satisfy one of the following two conditions:

1. no matter in the forming stage and the shaping stage, the air channel 211 is in a one-way outward exhaust state; according to the above conditions, the opening/closing assembly 24 can be realized by using a check valve, i.e., a check valve that is only in one-way exhausting direction to the outside is hermetically connected to the air passage 211 (e.g., located inside or outside the air passage 211); or

2. In the "shaping" stage, the air channel 211 is in a bidirectional conducting state, and in the "shaping" stage, the air channel 211 is converted into a bidirectional non-conducting state. According to the above conditions, the opening and closing element 24 can be a plug, an airtight tape, a valve or other means; therefore, in the "shaping" stage, the air channel 211 is in a two-way communication state, and after the sole is pressed to complete shaping and air discharge, and the sole is still continuously pressed, the air channel 211 is manually plugged or stuck by using a component such as a plug or an airtight adhesive tape, and then the sole is removed to apply force, thus completing the "shaping" stage.

According to the requirements of use, the design of the negative pressure auxiliary assembly 23 can have various considerations, and can achieve different effects:

1. as shown in fig. 3A and 3B, the positions covered or placed by the negative pressure auxiliary assembly 23 can be: 1-1, covering the whole insole; 1-2, covering the front sole area; 1-3, covering the arch region; 1-4. Covering the heel area; or 1-5. A combination of two or more of the foregoing.

2. Depending on the material and type of the vacuum assist assembly 23, the following can be distinguished:

open porous elastomeric materials, such as: foam, sponge, etc. and can be a single whole or be made up of multiple independent components; the term "porous" refers to the material itself having a plurality of pores or voids, the collective pores or voids being referred to as the gas-containing space 26;

2-2. An open hollow elastomer comprising: open hollow elastic round tubes, open hollow flat elastomers, open hollow spherical elastomers, open hollow elastic particles, and the like; wherein, the open hollow elastic particles refer to the particles filled in the outer cladding layer, have hollow interiors, and the hollow interiors are directly communicated with the outsides of the particles, so the open hollow elastic particles not only have the functions of the particles, but also can be used as the negative pressure auxiliary assembly;

2-3, the double check valve structure is a non-open hollow elastic body, and is provided with a first outlet and a second outlet which are respectively communicated from the inside to the outside of the hollow body, and the first outlet and the second outlet are respectively connected with a first check valve and a second check valve in an airtight way; the first check valve is designed to allow air outside the negative pressure auxiliary assembly to flow into the hollow interior (i.e., the air accommodating space 26) in one direction, and the second check valve allows air inside the hollow interior (i.e., the air accommodating space 26) to flow out of the negative pressure auxiliary assembly in one direction.

3. In addition, referring to fig. 5 (base:Sub>A-base:Sub>A heel sectional view of the formed insole of fig. 3B), when the user walks, the particles 22 of the upper half HU of the personalized insole 2 are shaped inbase:Sub>A state of being tightly attached to each other and not easily displaced due to the negative pressure, so the overall hardness is higher, meanwhile, the negative pressure auxiliary component 23 of the lower half HD of the personalized insole 2 can change the volume with the external force, so the personalized insole 2 hasbase:Sub>A buffer capacity, and besides providing the sole support force, the personalized insole 2 hasbase:Sub>A buffer property at the position where the negative pressure auxiliary component 23 is arranged;

4. as shown in FIG. 4, the negative pressure auxiliary component 23 occupies a portion of the volume when viewed in a longitudinal section of the personalized insole 2, so that the amount of particles 22 used can be greatly reduced to reduce the production cost of the personalized insole 2, while still being molded to fit the user's plantar three-dimensional configuration.

In the second embodiment of the present invention, the negative pressure auxiliary component is not limited to the block-shaped foam, but can be an open hollow elastic body, which is represented by a strip-shaped hollow elastic tube, as shown in the plurality of hollow elastic tubes (negative pressure auxiliary component 33) at the upper part of fig. 6, the open hollow elastic tube can also be made of a breathable material, so that, besides the relatively large air-containing space 36 in the tube itself, a plurality of small air-containing spaces (i.e., holes and pores) in the tube wall can be added; the air discharged from the negative pressure auxiliary component 33 can be finally discharged through the air channel 211 (such as the air channel 211 at the right middle part of fig. 6), and in the second embodiment, the opening and closing component 24 is an airtight adhesive tape and can be located at the outer side of the outer cladding 21.

Referring to fig. 6 again, in the second embodiment, a negative pressure auxiliary assembly 43 (such as the oblate non-open hollow elastic body at the bottom of fig. 6) with a double check valve structure is used, which is made of air-tight material or structure and is hermetically connected with a first check valve 431 and a second check valve 432, wherein the first check valve 431 only enables the external air of the negative pressure auxiliary assembly 43 to flow into the hollow interior (i.e. the air containing space 46) thereof, as shown by the arrow direction above the first check valve 431 in fig. 6; the second check valve 432 only allows the air in the hollow interior (i.e. the air accommodating space 46) of the negative pressure auxiliary assembly 43 to flow out to the outside, as shown by the arrow below the second check valve 432 in fig. 6, and is in airtight communication with the air passage 211; when the heel of the outer coating layer 21 is repeatedly stepped, squeezed and released by an external force, the air therein can sequentially flow out of the outer coating layer 21 through the first check valve 431, the air containing space 46, the second check valve 432 and the air channel 211. It is particularly mentioned here that a greater underpressure can also be generated in the outer coating 21 when the user steps on the underpressure-assisting element 43 continuously. Since the first check valve 431 and the second check valve 432 allow only one-way flow of air, any structure that can achieve the above-mentioned one-way flow of air, for example, a Duckbill valve (Duckbill valve), an air check valve (air check valve), and the like, belongs to the first check valve 431 and the second check valve 432.

Referring to fig. 7A, in a third embodiment of the present invention, the granules 22 can be first filled into a second containing space of an inner covering layer 25, wherein the inner covering layer 25 is made of a breathable material (such as a breathable fabric or a breathable plastic film with elasticity or flexibility), and the planar configuration thereof can match with the planar configuration of the whole or part of the sole of a foot, so that the inner covering layer 25 has a predetermined thickness to maintain a soft state, the granules 22 can move in the inner covering layer 25, and the granule diameter thereof is larger than the pore size of the inner covering layer 25, so that the granules 22 cannot be separated from the inner covering layer 25 under the external pressure. Also, the periphery of the inner cladding 25 can be sealed and it can be placed into the outer cladding 21 together with the inner pellets 22, i.e., the pellets 22 are indirectly placed into the outer cladding 21. In addition, the negative pressure auxiliary assembly 23 and the opening and closing assembly 24 can be located outside the inner cladding layer 25, so that the negative pressure auxiliary assembly 23, the opening and closing assembly 24 and the inner cladding layer 25 can be respectively arranged in the outer cladding layer 21 in the production process, the procedure is simple, and the negative pressure auxiliary assembly 23 and the opening and closing assembly 24 can be located at expected positions. In other embodiments of the present invention, the sub-atmospheric pressure auxiliary member 23 can also be disposed in the inner coating layer 25 together with the particles 22, as described above.

As shown in fig. 7B, when the user's sole steps on the top surface of the outer covering layer 21, the particles 22 in the inner covering layer 25 are shaped along with the displacement of the three-dimensional configuration of the sole, and the air in the inner covering layer 25 is discharged to the inner covering layer 25 due to the pressure exerted by the sole; in addition, the negative pressure auxiliary assembly 23 also discharges air under the external pressure, and the air discharged from the inner cladding 25 and the negative pressure auxiliary assembly 23 and the air originally in the outer cladding 21 are discharged to the outside of the outer cladding 21 through the air passage 211. Moreover, the air channel 211 is hermetically sealed, when the outer covering layer 21 is no longer stressed (i.e. no longer stepped), the restoring force of the negative pressure auxiliary component 23 itself will force it to suck the external air, so that the particles 22 shaped in the inner covering layer 25 are shaped in a state of being tightly attached to each other and not easily displaced due to the negative pressure, so as to obtain the personalized insole 2.

In addition, referring to fig. 7C, in order to keep the personalized insole 2 in its shaped state for a long time, it can also perform a heating operation after finishing the shaping (i.e. the particles 22 are shaped in a state of being tightly attached to each other and not easily displaced), and the air channel 211 is hermetically sealed. The particles 22 can be made of thermoplastic elastomer material (e.g., TPU, TPEE, TPS, TPR, SEBS 8230), etc.) with low melting point or low incipient melting temperature (e.g., 60-85 ℃), which is lower than the melting point or incipient melting temperature of other components of the personalized insole 2 (e.g., the outer covering 21, the negative pressure auxiliary component 23 8230, etc.), i.e., when the particles 22 are in a molten state, the other components of the personalized insole 2 can also maintain their integrity without being in a molten state. The heating operation can be performed by hot boiled water, an oven, a blower, or a microwave oven, and it is not necessary to use a special heating device, thereby improving convenience for the individual to use. During the heating operation, at least the surface of the particles 22 is in a molten state, so that the adjacent particles 22 can be welded together to form a single-piece, thereby forming the personalized insole 2 with a long service life. Thus, if the outer coating 21 or the inner coating 25 is damaged after a long time of use, the personalized insole 2 can still maintain the original three-dimensional configuration of the sole of the foot due to the particles 22 being adhered together, so as to effectively prolong the service life of the personalized insole 2.

In addition to the thermoplastic elastomer material used to make the particles 22, in other embodiments of the present invention, the particles 22 can be uniformly mixed with the bonding material 27 such that the bonding material 27 can be uniformly attached to the surface of each particle 22 (as shown in fig. 8), wherein the bonding material 27 can be in the form of powder, liquid paste 8230, etc., and comprises an adhesive material (Binder) (e.g., TPU hot melt adhesive, EVA hot melt adhesive 8230, etc.) 271 and/or an Absorbent material (adsorbent) (e.g., infrared Absorbent material, electromagnetic wave Absorbent material 8230, etc.) 273, and the adhesive material 271 and the Absorbent material 273 can be attached to the surface of the particles 22 as shown in fig. 8 or completely cover the surface of the particles 22. The melting point of the bonding material 27 is lower than the melting points of other components of the customized insole 2 (e.g., the granules 22, the outer covering 21, the sub-assembly 23 \8230; etc.), and the bonding material 27 and the granules 22 can be directly or indirectly filled into the outer covering 21. When the personalized insole 2 further comprises an inner coating layer 25, the particle size of the bonding materials 27 can be larger than the air-permeable pore size of the inner coating layer 25, so that the bonding materials 27 can only be displaced in the inner coating layer 25. After heating, the bonding material 27 can be melted to fuse the adjacent particles 22 together, thereby forming a long-lived personalized insole 2.

It is specifically mentioned that the personalized insole 2 can be repeatedly shaped when no heating operation is performed, and the user only needs to open the air channel 211 to allow the outside air to enter the outer covering layer 21. In addition, the number of the air passages 211 of the present invention is not limited to one, and may be multiple (as shown in fig. 6), when one of the air passages 211 is occupied (as in the second embodiment, the bottom air passage 211 is exclusively occupied by the second check valve 432), the other air passage 211 can be opened to allow the external air to enter the outer cladding 21. The air channel 211 may also be used to fill or remove particles 22, if desired.

Referring to fig. 2 and 9, in step 501, a filling operation is performed, and according to the design of the personalized insole 2, the opening and closing element 24 and the negative pressure auxiliary element 23 are disposed at predetermined positions of the outer covering layer 21, and the granules 22 are directly or indirectly filled into the outer covering layer 21 (for example, the granules 22 can be filled into the inner covering layer 25 first, and then the inner covering layer 25 is installed into the outer covering layer 21), so that the outer covering layer 21 has a predetermined thickness, and the granules 22 can move in the outer covering layer 21 (or the inner covering layer 25), and then the filling opening is hermetically sealed to complete the filling operation; then, in step 502, a pre-forming operation can be performed, which is usually performed at the factory, i.e. according to a preliminary three-dimensional sole configuration, which generally refers to some representative three-dimensional sole models, for example, the sole state of most people or the sole state designed according to the expectation of the user, then the filled insole is laid flat or placed on a supporting fixture (i.e. a shoe mold), the opening and closing component 24 makes the air channel 211 in a one-way outward exhaust state or a two-way conduction state, the preliminary three-dimensional sole configuration is placed on the outer covering layer of the insole, and a proper pressure is applied to make the particles 22 complete the shaping along with the displacement along the air-tight three-dimensional configuration, then an air-pumping device (e.g. a vacuum pump) is used to pump the outer covering layer 21 through the air channel 211 to obtain a strong shaping (higher vacuum) effect, and finally the air channel is used to complete the pre-forming operation. The operation can make the insole maintain a representative state for long term storage, and is also convenient for the use of users in the future.

In addition, in step 503, a forming operation is performed, in a case that the air pressure inside and outside the outer covering layer 21 is the same or substantially the same, and the opening and closing component 24 makes the air channel be in a one-way outward exhaust state or a two-way conduction state, in a state that the whole or part of the sole of the foot of the user steps on and applies pressure on the outer covering layer 21, the particles 22 can be displaced along with the whole or part of the three-dimensional configuration of the sole of the foot to complete the forming, and the air inside the outer covering layer 21 can be discharged out of the outer covering layer 21 through the air channel 211 due to the pressure applied by the whole or part of the sole of the foot, meanwhile, the negative pressure auxiliary component 23 can be influenced by the pressure to reduce the occupied volume thereof, and the air inside thereof can be discharged out of the outer covering layer 21 through the air channel 211, at this time, the top surface of the covering layer 21 forms a three-dimensional configuration matching and conforming to the sole state of the user; in step 504, a shaping operation is performed to make the opening and closing component 24 maintain the air channel in a one-way outward exhaust state or switch to a two-way non-conducting state, so that the air outside the outer covering layer 21 cannot flow into the outer covering layer 21, after the pressure applied by the sole is removed, the negative pressure auxiliary component 23 expands due to its own restoring force and absorbs the residual air among the particles 22, so that the particles 22 are shaped in a state of being tightly attached to each other and not easily displaced due to the negative pressure, thereby obtaining the personalized insole 2. Furthermore, in step 505, a heating operation is performed to directly or indirectly fuse the adjacent particles 22 into a whole, so as to form a long-life personalized insole 2; in addition, for some materials, gas is released during heating, which will destroy the original negative pressure state and change the shaped state, so that in step 505, the mode of heating and vacuumizing the insole can be adopted to ensure that the three-dimensional configuration is not changed. In the above-described process of the present invention, steps 502 and 505 can be omitted according to product requirements.

It is specifically stated that when the opening and closing assembly 24 is a check valve, it has the following advantages:

1. the individual insole 2 can be directly placed in the shoe, and the forming (shaping and shaping) of the individual insole 2 can be automatically completed during treading or walking, which avoids the need of manually forming and shaping the insole outside the shoe, and then the individual insole 2 is placed in the shoe for use. The main reason is that if the opening and closing assembly 24 is a plug or an airtight tape 8230, it is required to be manually operated to switch between conduction and non-conduction to the air passage 211, which is required to be performed outside the shoe.

2. Which conforms to the three-dimensional configuration of the sole of the foot of the user under the daily action.

3. During daily activities, vacuum is automatically replenished (to avoid the trouble of microleakage).

4. Can be used for molding the personalized insole meeting the requirements of special configuration. Such as: in order to achieve the correction purpose, the three-dimensional configuration of the insole is desired to meet the three-dimensional configuration of the sole of a flat foot patient when the sole of the foot is slightly pressed (or not pressed), or the insole is desired to have special configuration requirements (such as stimulating acupuncture points) of inclination, protrusion and the like at a certain position and a certain direction, at the moment, if the insole with the check valve is used, the outer coating layer can be properly pressed manually, so that part of air in the outer coating layer (and/or the inner coating layer) is slowly exhausted out of the outer coating layer through the air channel under the control, when a certain slight negative pressure is reached, the particles can be in contact with each other and keep a state of not moving arbitrarily, but can be easily moved and keep the moved three-dimensional configuration when a finger applies force to the outer coating layer; by using the manual mode and comparing with the foot, if necessary, a proper tool is used for assisting the shaping, the shaping operation required by the special configuration can be easily and quickly completed, and finally the establishment of negative pressure is enhanced to complete the shaping operation, namely the individualized insole 2 meeting the special configuration requirement is molded.

The above description is only for the preferred embodiment of the present invention, and the scope of the claims of the present invention is not limited thereto, and equivalent changes and modifications that can be easily made by those skilled in the art according to the disclosure of the present invention should not be departing from the protection scope of the present invention.
