Description

Technical Field

[0001] The present invention relates to the technical field of chewing training devices, and in particular to a chewing training device and a chewing force testing method. Background Art

[0002] Among the elderly, as their physical functions decline, their chewing ability also decreases. Currently, the devices for exercising chewing function on the market usually use springs, but the chewing resistance continues to increase during the compression process of the springs. For elderly users, since their teeth are brittle and some tooth roots are not strong, the sudden increase in chewing resistance can easily damage their teeth, which is a disadvantage. Summary of the Invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and to provide a chewing trainer and a chewing force testing method, which can ensure the uniformity of chewing resistance and reduce the possibility of tooth damage in users.

[0004] The present invention discloses a chewing trainer, comprising a capsule body 1 and a capsule body 2. A cavity 1 is provided in the capsule body 1, and the capsule body 1 can be squeezed to compress the cavity 1. The capsule body 1 is connected to a connecting tube, and the connecting tube is connected to a container body. The container body is provided with a closed cavity 2. The cavity 1 and the cavity 2 are connected through the connecting tube. The capsule body 2 is located in the cavity 2. The capsule body 2 is connected to an air pipe, and a compressible cavity is provided in the capsule body 2 and is connected to the air pipe. The air pipe extends out of the container body, and the air pipe is equipped with a one-way valve and a connecting head. The flow direction of the one-way valve is from the air pipe to the outside, and the connecting head is externally connected to an inflation device.

[0005] Furthermore, when the pressure difference between the inside and outside of the second bladder changes, the second bladder can contract or expand.

[0006] Furthermore, a top cover is installed on the top of the container body, the upper end of the air pipe extends out of the upper end of the top cover, and the air pipe extending out of the upper end of the top cover is installed with a one-way valve and a connector.

[0007] Furthermore, the capsule is C-shaped.

[0008] Furthermore, in the initial state, the pressure difference between the inside and outside of the bladder is zero.

[0009] Furthermore, the one-way valve includes a fixed block, which has a conical surface on the side away from the trachea and abuts against a sealing ball. The sealing ball abuts against a spring on the side away from the fixed block. The spring abuts against an adjusting block on the side away from the sealing ball. The adjusting block is threadedly connected to the one-way valve.

[0010] Furthermore, the connector is connected to a voltage stabilizer, which is in communication with the inflation device.

[0011] The present invention also discloses a method for testing chewing force, which uses a chewing trainer and includes the following steps:

[0012] Introduce gas into the second and first chambers, and into the second bladder. The air pressure in the second bladder reaches the critical opening value of the one-way valve. The air pressure in the second bladder is the same as that in the second and first chambers, and the first bladder is inflated.

[0013] Place capsule 1 between the user's upper and lower teeth, and chew capsule 1 with the teeth. Capsule 1 contracts, and the air pressure in cavity 2 and cavity 1 increases. Capsule 2 contracts, and the air pressure in capsule 2 increases. The one-way valve opens and discharges gas to reduce the air pressure in capsule 2. Capsule 2 moves in and contracts, and the air pressure in cavity 2 and cavity 1 decreases and approaches the initial pressure value.

[0014] After a chewing is completed, the teeth release capsule 1, capsule 1 rebounds, and gas is introduced into capsule 2 to expand capsule 2 back to its initial state. The pressure difference between the inside and outside of capsule 2 returns to zero, and the air pressure value in capsule 2 is used to test the user's chewing force.

[0015] Beneficial effects of the present invention:

[0016] During chewing training, the air pressure in capsule 2 is the critical value for opening the one-way valve. The air pressure in capsule 2 is the same as the air pressure in chamber 1 and chamber 2. During the compression process of chamber 1, the air pressure in chamber 1 and chamber 2 continues to increase, and a pressure difference occurs inside and outside capsule 2. Capsule 2 contracts, and the air pressure in capsule 2 increases and is greater than the opening pressure of the one-way valve. The one-way valve allows the gas in capsule 2 to overflow, causing the gas pressure in capsule 2 to return to the critical pressure value for opening the one-way valve. After capsule 2 contracts, the volume of chamber 2 increases and the pressure decreases, thereby keeping the pressure value of chamber 1 stable during the compression process of capsule 1. Since elderly users have brittle teeth and some tooth roots are not strong, the chewing trainer in this embodiment can ensure the uniformity of chewing resistance when users perform chewing training, preventing elderly users from damaging their teeth due to the large chewing resistance during use.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in this embodiment with reference to the accompanying drawings. Obviously, the described embodiments 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.

[0023] like Figure 1 As shown, a chewing trainer includes a container body 4, which defines a second cavity 41. A top cover 42 is mounted at the top opening of the container body 4, forming a closed cavity 41. An air tube 81 is fixedly mounted to the top cover 42, the lower end of which passes through the top cover 42 and extends into the second cavity 41 of the container body 4. A second bladder 8 is connected to the bottom of the bladder 81. The second bladder 8 defines a compressible cavity and is in communication with the bottom of the bladder 81. The second bladder 8 is located within the second cavity 41 and can contract or expand when the pressure differential between the inside and outside of the second bladder 8 changes.

[0024] like Figure 1 、 Figure 2 As shown, the upper end of the air pipe 81 extends out of the upper end of the top cover 42. The air pipe 81 extending out of the upper end of the top cover 42 is installed with a one-way valve 7 and a connector 2. The flow direction of the one-way valve 7 is from the air pipe 81 to the outside. When the air pressure in the air pipe 81 reaches the one-way valve flow opening value, the gas in the air pipe 81 overflows to the outside through the one-way valve 7. Specifically, a flow channel is provided in the one-way valve 7. The one-way valve 7 includes a fixed block 71. The fixed block 71 is located in the flow channel. The fixed block 71 is provided with a channel for gas circulation. The fixed block 71 is provided with a conical surface on the side away from the air pipe 81 and abuts against a sealing ball 72. The sealing ball 72 abuts against a spring 73 on the side away from the fixed block 71. The spring 73 abuts against an adjustment block 74 on the side away from the sealing ball 72. The adjustment block 74 is threadedly connected to the one-way valve 7. When the sealing ball 72 abuts the conical surface of the fixing block 71, the one-way valve 7 is closed. When the air pressure in the air pipe 81 increases to push the sealing ball 72 away from the conical surface, the one-way valve 7 opens. The opening pressure of the one-way valve 7 is controlled by adjusting the compression degree of the spring 73 by the adjusting block 74.

[0025] The connector 2 is connected to an external inflation device, and a pressure stabilizer is also connected between the connector 2 and the inflation device. Gas is filled into the second bladder 8 through the inflation device to form an air pressure value in the second bladder 8 that is the same as the critical pressure for opening the one-way valve.

[0026] like Figure 1 As shown, the container body 4 is also equipped with an air inlet connector 6 and a pressure gauge 5. Gas is introduced into the second chamber 41 through the air inlet connector 6, and the air pressure value in the second chamber 41 is monitored through the pressure gauge 5.

[0027] like Figure 1 As shown, the container body 4 is connected to the connecting pipe 3, and the connecting pipe 3 is connected to the capsule 1 on the side away from the container body 4, as shown in FIG. Figure 3 As shown, the capsule 1 is a C-shaped structure, combined with Figure 1 、 Figure 4 , a cavity 11 is provided in the capsule 1, and the cavity 11 is connected to the cavity 2 41 of the container body 4 through the connecting tube 3. When used for chewing training, the air pressure in the capsule 2 8 is the critical value for the opening of the one-way valve 7, and the air pressure in the capsule 2 8 is the same as the air pressure values ​​of the cavity 11 and the cavity 2 41. After the capsule 1 is placed in the user's mouth, the user bites the upper and lower surfaces of the capsule 1 with his teeth and squeezes the capsule 1. During the compression process, the air pressure in the cavity 11 continues to increase. Since the cavity 11 is connected to the cavity 2 41, the air pressure in the cavity 2 41 also increases synchronously. At this time, a pressure difference occurs between the inside and outside of the capsule 2 8, the capsule 2 8 contracts, and the air pressure in the capsule 2 8 increases and is greater than the opening pressure of the one-way valve 7. The one-way valve 7 allows the gas in the capsule 2 8 to overflow, causing the gas pressure in the capsule 2 8 to return to the critical pressure value for the opening of the one-way valve 7. After the second capsule 8 contracts, the volume of the second chamber 41 increases and the pressure decreases, thereby maintaining a stable pressure in the first chamber 11 during the compression of the first capsule 1. Because elderly users have brittle teeth and some tooth roots are not strong, the chewing trainer in this embodiment ensures uniform chewing resistance during chewing exercises, preventing tooth damage caused by excessive chewing resistance during use.

[0028] After the chewing of capsule 1 is completed, capsule 1 contracts and then rebounds. At this time, the volume of cavity 11 increases, the overall air pressure of cavity 11 and cavity 2 41 decreases, the volume of capsule 2 8 expands slightly, and the air is quickly replenished into capsule 2 8 through the inflation device connected to the connector 2 to make up for the loss of air overflowing from the one-way valve 7, so that cavity 11 and cavity 2 41 return to the state before chewing, and the air pressure difference inside and outside capsule 2 8 returns to zero.

[0029] like Figure 1 、 Figure 2 As shown, when the air pressure of the second cavity 41 is adjusted through the air inlet connector 6, the opening pressure of the one-way valve 7 is controlled by adjusting the compression degree of the spring 73 by adjusting the adjustment block 74, thereby adjusting the air pressure value inside the capsule 2 8 to match the air pressure of the second cavity 41, and then adjusting the chewing resistance generated by the compressed capsule 1.

[0030] A method for testing chewing force, using the above-mentioned chewing trainer, comprises the following steps:

[0031] Gas is introduced into the second cavity 41 and the first cavity 11 through the air inlet joint 6, and gas is introduced into the second bladder 8 through the connector 2. The air pressure value in the second bladder 8 reaches the opening critical value of the one-way valve 7. The air pressure value in the second bladder 8 is the same as the air pressure value in the second cavity 41 and the first cavity 11. The pressure difference between the inside and outside of the second bladder 8 is zero, and the bladder 1 is inflated.

[0032] When capsule 1 is placed between the user's upper and lower teeth and the teeth chew capsule 1, it contracts, increasing the air pressure in chambers 2 41 and 11. Then, capsule 2 8 contracts, increasing the air pressure in capsule 2 8. One-way valve 7 opens and expels air, causing the air pressure in capsule 2 8 to drop. Then, capsule 2 8 further contracts, causing the air pressure in chambers 2 41 and 11 to decrease and approach the initial pressure value, which is the opening threshold of one-way valve 7. Therefore, when the user performs chewing exercises using the chewing trainer of this embodiment, the chewing resistance is uniform, preventing tooth damage in elderly users due to high chewing resistance.

[0033] After a chewing session, the teeth release capsule 1, causing it to rebound. Air is then introduced into capsule 2 8 through connector 2, causing it to expand back to its initial state, returning the pressure differential inside and outside capsule 2 8 to zero. The air pressure in chamber 2 41, displayed by barometer 5, serves as a criterion for assessing the user's chewing force.

[0034] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
