Description

Technical Field

[0001] This invention belongs to the field of assistive devices for the elderly, and specifically relates to an assistive chewing device. Background Technology

[0002] As the population ages, some elderly people face the challenge of declining chewing ability due to problems such as oral function decline and tooth loss. They have difficulty chewing food thoroughly during daily meals, which not only affects nutrient absorption but also easily causes safety hazards such as choking. Therefore, chewing aids have become important devices to improve the eating experience of the elderly and are widely used in home-based elderly care, rehabilitation and nursing institutions, and community elderly care services.

[0003] Existing chewing aids mostly process food through simple crushing structures, resulting in a limited food processing flow that only crushes or compresses the food. The processed food is either too loose and prone to choking, or too tightly compressed and difficult to swallow, failing to meet the needs of elderly people with different chewing abilities. Moreover, these devices lack effective self-cleaning structures, making it difficult to remove residues from the surface of the components during use. Long-term accumulation not only affects the stability of the device's operation but may also breed bacteria, posing a hygiene hazard. Therefore, there is a need to design a new chewing aid. Summary of the Invention

[0004] The purpose of this invention is to provide an auxiliary chewing device with a simple structure and reasonable design in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions:

[0006] An auxiliary chewing device includes a main support with a closing mechanism at its top. The main support also includes a shredding mechanism and a compression mechanism. The shredding mechanism is connected to a hand-cranked drive mechanism, and the compression mechanism is connected to an adjustment mechanism. Support feet are symmetrically arranged on both sides of the main support. The main support includes a support frame with a feed hopper at its top and a discharge port at its bottom. Closing side plates abut against both sides of the support frame, and outer support plates abut against the closing side plates. Limiting rods are locked in through holes at the four corners of the closing side plates by nuts. Limiting blocks are symmetrically fitted onto the limiting rods, abutting against the inner edge of the support frame. The shredding mechanism includes a drive shaft and a driven shaft. Shredding wheels are fitted in the middle of both the drive and driven shafts. Isolation wheels are evenly fitted onto both the drive and driven shafts, located between the shredding wheels. The shredding wheels and isolation wheels on the drive and driven shafts are arranged alternately. Cleaning rods are evenly fitted onto the limiting rods, abutting against the isolation wheels.

[0007] As a further optimization of the present invention, the hand-cranked drive mechanism includes a transmission gear fixedly sleeved on one end of the drive shaft and the driven shaft, and the transmission gears on the drive shaft and the driven shaft mesh with each other. Protective covers are fixedly installed on both sides of the closed side plates by screws, the transmission gears are located inside the protective covers, and a rocker arm is provided at the end of the drive shaft away from the transmission gears through the protective covers.

[0008] As a further optimization of the present invention, the compression mechanism includes a fixed shaft rotatably connected between the outer support plates and an adjusting shaft slidably connected between the outer support plates. Compression wheels are uniformly sleeved in the middle of both the fixed shaft and the adjusting shaft, and the protrusions of the compression wheels on the fixed shaft and the adjusting shaft engage with each other.

[0009] As a further optimization of the present invention, the adjustment mechanism includes an eccentric shaft rotatably connected between the outer support plates, with both ends of the eccentric shaft rotatably connected to the connecting plates, and both ends of the adjustment shaft rotatably connected to the connecting plates. Locking sleeves are fixedly sleeved on both ends of the eccentric shaft, and an adjustment wheel is provided on one side of the locking sleeve. Locking grooves are evenly provided on the locking sleeve.

[0010] As a further optimization of the present invention, a locking frame is fixedly installed on one side of the closed side plate, a locking head is slidably connected to the bottom of the locking frame, a locking spring is provided in the locking frame, the bottom end of the locking spring abuts against the locking head, and the locking head is detachably abutted in the locking groove.

[0011] As a further optimization of the present invention, the closing mechanism includes a rotating support symmetrically fixed to the top of the support frame, a rotating shaft rotatably connected to the rotating support, and a first bracket fixed to one end of the rotating shaft.

[0012] As a further optimization of the present invention, a second bracket is provided on the first bracket, and an upper bracket and a support sleeve are rotatably connected to the second brackets on both sides respectively. The upper bracket and the support sleeve are connected to each other by a support spring, and a flip plate is fixedly sleeved in the middle of the rotating shaft.

[0013] As a further optimization of the present invention, the top of the inner wall of the support frame is symmetrically provided with abutting springs, which abut against the cleaning bird rod, and connectors are fixedly installed on both sides of the bottom of the abutting springs.

[0014] As a further optimization of the present invention, a follower ring is fixedly sleeved on the isolation wheels on both sides of the middle of the drive shaft and the driven shaft. The follower ring is provided with a push protrusion and a detachable abutment connector.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention uses a shredding wheel to simulate the tearing action of teeth, followed by compression and shaping with a compression wheel. This process can process various foods into a uniform and easy-to-swallow form, effectively reducing the chewing and swallowing burden on the elderly and reducing the risk of choking. With the adjustable gap mechanism, the bite gap of the compression wheel can be flexibly adjusted, and the degree of compression can be precisely adjusted according to the texture of the food and the user's chewing ability to meet diverse eating needs.

[0017] 2. The invention involves a cleaning bird rod that adheres to the surface of the isolation wheel of the shredding mechanism. When the isolation wheel rotates synchronously with the drive shaft and driven shaft, the cleaning bird rod continuously scrapes the side wall of the isolation wheel and the shredding wheel, promptly removing food residues adhering to it during the shredding process. This effectively prevents residues from accumulating in the teeth or gaps of the wheel, preventing a decrease in the meshing accuracy of the shredding wheel due to residue jamming. It ensures continuous and stable shredding and compression actions, while also reducing component wear caused by long-term residue residue and extending the service life of the device.

[0018] 3. The pressure spring of this invention presses the cleaning bird stick body with elastic contact, providing a continuous downward preload to the cleaning bird stick. When processing hard food, even if the hard residue generated exerts an upward pushing force on the cleaning bird stick, the elastic pressure of the pressure spring can counteract this force, ensuring that the cleaning bird stick always fits tightly against the wheel surface and will not tilt or shift. It can stably clean food residue of different textures.

[0019] 4. In this invention, the follower ring rotates synchronously with the isolation wheel. The push protrusion on its outer wall periodically abuts against the connecting piece of the pressing spring, causing the pressing spring to deform elastically and push the cleaning bird rod upward. After the push protrusion passes the connecting piece, the pressing spring returns to its original position, causing the cleaning bird rod to quickly rebound downward and strike the isolation wheel, causing the cleaning bird rod to vibrate intermittently. The vibration can shake off the food residue collected by scraping at the end of the cleaning bird rod, preventing the residue from accumulating and clumping on the surface of the bird rod, realizing the self-cleaning of the cleaning bird rod, preventing the accumulated residue from causing secondary pollution to the wheel body, further improving the cleanliness and hygiene level of the device, and ensuring the safety of the processed food.

[0033] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0034] Example: Please refer to Figures 1-12An auxiliary chewing device includes a main support 1. A sealing mechanism 2 is located on the top of the main support 1. During food processing, the sealing mechanism 2 seals the top of the device to prevent food from splashing. A shredding mechanism 3 and a compression mechanism 4 are mounted on the main support 1. The shredding mechanism 3 is located above the compression mechanism 4. Food to be chewed is first shredded and chewed on the shredding mechanism 3, and then compressed by the compression mechanism 4. The shredding mechanism 3 is connected to a hand-cranked drive mechanism 5, which allows the food to be shredded under its operation. The compression mechanism 4 is connected to an adjusting mechanism 6. Linked with the gap adjustment mechanism 6, the compression gap of the compression mechanism 4 can be precisely controlled through the adjustment of the gap adjustment mechanism 6, thereby flexibly adjusting the degree of compression of the shredded food to meet the needs of different chewing abilities; the main support 1 includes a support frame 101, on which support feet 7 for supporting the entire device are fixedly installed by bolts to ensure the stability of the placement and prevent tipping during operation. The top of the support frame 101 is provided with a feeding hopper 107 for feeding. The feeding hopper 107 is flared, which is convenient for the elderly to quickly feed and can prevent food from spilling. The bottom of the support frame 101 is provided with a discharge hopper for pressurized food. The food discharge port 106 corresponds to the lower part of the compression mechanism 4 and is used to centrally discharge the compressed food. The support frame 101 has closed side plates 102 abutting against both sides, and an outer support plate 105 abutting against the closed side plates 102. Through holes are opened at the four corners of the closed side plates 102, and limiting support rods 103 pass through the through holes. The two ends of the limiting support rods 103 are locked in place by nuts. Under the locking action of the limiting support rods 103 and nuts, the closed side plates 102 are tightly locked to both sides of the support frame 101, forming a sealed food shredding and compression processing space, effectively preventing… To prevent food residue from splashing and contaminating, limiting blocks 104 are symmetrically fitted on the limiting support rod 103. The limiting blocks 104 are located inside the processing space and precisely abut against the inner edge of the support frame 101. The positioning function of the limiting blocks 104 restricts the installation offset of the support frame 101, ensuring the assembly accuracy of each component of the device and ensuring smooth coordination of the shredding and compression actions. Food that requires chewing first enters the shredding mechanism 3 through the feeding hopper 107, is shredded and refined, and then falls naturally to the compression mechanism 4 for secondary compression and shaping, finally forming an easily swallowable food form that is discharged from the discharge port 106.The shredding mechanism 3 includes a drive shaft 301 and a driven shaft 302. The middle sections of both the drive shaft 301 and driven shaft 302 are hexagonal columnar structures, and multiple shredding wheels 303 are evenly mounted on these hexagonal columnar structures. Isolation wheels 304 are evenly mounted on the hexagonal columnar structures of both the drive shaft 301 and driven shaft 302, located between the shredding wheels 303. Under the action of the isolation wheels 304, the shredding wheels 303 on the drive shaft 301 and driven shaft 302 are arranged in an alternating pattern. The sidewalls of the shredding wheels 303 have tooth-like structures. When the drive shaft 301 rotates under the drive mechanism, it will trigger the driven shaft 302. 02. Reverse rotation causes the tooth-like structures on the interlocking shredding wheels 303 on both sides to mesh and rotate, precisely simulating the tearing action of human teeth. This efficiently shreds and refines the food entering the processing space, assisting the elderly in chewing. Cleaning rods 8 are evenly fitted onto the limiting support rod 103. The arc-shaped surface at the bottom of the cleaning rod 8 can abut against the isolation wheel 304, used to shred food residue remaining on the shredding wheel 303 and the isolation wheel 304. As the isolation wheel 304 rotates with the shaft, the cleaning rod 8 continuously scrapes the surface of the isolation wheel 304 and both sides of the shredding wheel 303, preventing residue accumulation from affecting the operation of the device and ensuring cleanliness and hygiene.

[0035] Please see Figures 1-2 and Figures 4-5 The closing mechanism 2 includes a rotating support 201 symmetrically fixed to the top of the support frame 101 by fixing bolts. The rotating support 201 is located on both sides of the feed hopper 107 and is used to provide a stable rotation base for the entire closing mechanism 2. A rotating shaft 202 is rotatably connected to the rotating support 201. One end of the rotating shaft 202 is provided with a rotating ring with anti-slip grooves. The anti-slip grooves can increase the friction when rotating with fingers, making it easier for the elderly to manually rotate and reducing the difficulty of exerting force. A first bracket 203 is fixed to the end of the rotating shaft 202 away from the rotating ring. A second bracket 204 is sleeved on the through hole of the first bracket 203. The two sides of the second bracket 204 are rotatably connected to an upper bracket 205 and a support sleeve 206, respectively. The upper bracket 205 and the support sleeve 206 are connected to each other by a support spring 207. A flip plate 208 is fixedly sleeved in the middle of 202. The flip plate 208 is located in the food processing space and is directly below the feed hopper 107. When food is fed from the feed hopper 107, the rotating ring can be manually rotated to drive the rotating shaft 202 to rotate, thereby driving the flip plate 208 to flip synchronously. On the one hand, it can control the opening and closing of the processing space. After feeding, the flip plate 208 closes to prevent food residue from splashing from the feed hopper 107 during the shredding process. On the other hand, the flipping action of the flip plate 208 can help guide the fed food downward to the position between the two shredding wheels 303, avoiding food accumulation and jamming under the feed hopper 107. At the same time, the upper bracket 205 and the support sleeve 206 form an elastic linkage structure through the support spring 207, which can automatically reset after the food is fed.

[0036] Please see Figures 1-3 The hand-cranked drive mechanism 5 includes a transmission gear 501 fixedly sleeved on the same end of the drive shaft 301 and the driven shaft 302. The transmission gear 501 on the drive shaft 301 and the driven shaft 302 are meshed with each other, and the synchronous reverse transmission of power is achieved through gear meshing. When the drive shaft 301 rotates, it can drive the driven shaft 302 to rotate in the opposite direction through the transmission gear 501, thereby driving the drive shaft 301 of the shredding mechanism 3 to mesh with the shredding wheel 303 on the driven shaft 302 to complete the food shredding action. Protective covers 502 are fixedly installed on the closed side plates 102 on both sides by screws. 501 is completely enclosed inside the protective cover 502. The protective cover 502 can prevent clothing, fingers, etc. from getting caught in the transmission gear 501 during operation, thus preventing safety hazards. It can also block external impurities from adhering to the gear teeth, thus avoiding affecting the meshing accuracy and smooth rotation. The end of the drive shaft 301 away from the transmission gear 501 passes through the protective cover 502 and is fixedly connected to a rocker arm 503. The rocker arm 503 adopts an extended rod design, which can be manually cranked by the elderly by holding the rocker arm 503 to provide power without relying on electricity. It can flexibly control the rotation speed and force, adjust the shredding rhythm according to the hardness of the food, and improve the convenience and adaptability of use.

[0037] Please see Figure 5 and Figure 8 The compression mechanism 4 includes a fixed shaft 401 and an adjusting shaft 402 arranged in parallel. The fixed shaft 401 is rotatably connected between the outer support plates 105 and its position remains fixed, providing a stable reference for the compression action. The adjusting shaft 402 is slidably connected in a corresponding groove in the outer support plate 105 and can move laterally along the groove to adjust the distance between it and the fixed shaft 401. The middle part of the fixed shaft 401 and the adjusting shaft 402 is a hexagonal columnar structure, and a compression wheel 403 is uniformly fixedly sleeved on the middle part of both the fixed shaft 401 and the adjusting shaft 402. The compression wheel 403 has uniformly distributed protrusions, and the protrusions on the coaxial compression wheel 403 are staggered. The fixed shaft 401 and the adjusting shaft 402 are aligned. The protrusions on the compression rollers 403 interlock and fit together. When the food processed by the shredding mechanism 3 falls to the compression mechanism 4, the fixed shaft 401 and the adjusting shaft 402 rotate synchronously in opposite directions under the pressure of the food. The interlocking protrusions of the compression rollers 403 squeeze and shape the food, compressing the loose shredded food into a uniform, easy-to-swallow block or strip shape, further reducing the difficulty of swallowing for the elderly. At the same time, the sliding design of the adjusting shaft 402, together with the gap adjustment mechanism 6, can flexibly adjust the interlocking gap between the compression rollers 403 according to the type of food and the swallowing ability of the elderly, ensuring the compression effect while avoiding the mechanism jamming caused by hard food, thus improving the adaptability and stability of the device.

[0038] Please see Figures 1-5 and Figure 10 The adjustment mechanism 6 includes an eccentric shaft 601 rotatably connected between the outer support plates 105. Both ends of the eccentric shaft 601 are rotatably connected to the connecting plate 602. The adjusting shaft 402 of the compression mechanism 4 is rotatably connected at both ends to the pre-drilled holes in the connecting plate 602, forming a linkage-type eccentric rotation structure. When the eccentric shaft 601 rotates, its eccentric structure drives the adjusting shaft 402 to slide laterally along the groove of the outer support plate 105 via the connecting plate 602, thereby adjusting the distance between the adjusting shaft 402 and the fixed shaft 401, thus adjusting the meshing gap of the compression wheel 403. Correspondingly, the two closed side plates 102 are positioned at the positions corresponding to the eccentric shaft 601. A sliding groove is provided for the movement of the adjusting shaft 402, which will not interfere with the position adjustment of the adjusting shaft 402. Although the closed side plate 102 and the outer support plate 105 are provided with sliding grooves, the gap adjustment through the eccentric shaft 601 is affected by the eccentric size, and the adjustment range is small. Therefore, the sliding groove reserved for gap adjustment is also a small-sized sliding groove. The connection between the space enclosed by the closed side plate 102 and the support frame 101 and the sliding groove is blocked by the compression wheel 403 provided on the adjusting shaft 402, so there will be no problem of food residue falling and getting stuck. Locking sleeves 603 are fixedly sleeved at both ends of the eccentric shaft 601, and an adjusting wheel 60 is fixed on one side of the locking sleeve 603. 4. The adjusting wheel 604 has anti-slip textures, making it easy for elderly people to manually rotate and reducing the difficulty of adjustment; the locking sleeve 603 has evenly spaced locking grooves 605, and a locking frame 606 is fixedly installed on the closed side plate 102 on one side by screws. The bottom of the locking frame 606 has a guide groove, and a locking head 607 is slidably connected in the guide groove, which can move up and down along the groove. The locking groove 605 and the locking head 607 are adapted to form a positioning structure. The locking frame 606 has a locking spring 608 inside. The top end of the locking spring 608 abuts against the bottom of the upper support column threaded to the top of the locking frame 606, and the bottom end elastically abuts against the locking head 607. The locking head 607 is provided with a continuous downward preload, so that the locking head 607 is normally in contact with the locking groove 605, thereby locking the adjusted position and preventing the eccentric shaft 601 from rotating due to vibration during use. This ensures the stability of the gap of the compression wheel 403. Although the bushing of the adjusting shaft 402 slides in the groove on the outer support plate 105, when the gap needs to be adjusted, the rotating adjusting wheel 604 drives the eccentric shaft 601 to rotate. During the process, the torque overcomes the spring force and moves the locking head 607 upward. After the adjustment is completed, the locking head 607 is reset and locked into the corresponding locking groove 605 under the action of the locking spring 608, thus completing the locking. The operation is convenient and the positioning is reliable.

[0039] Please see Figures 11-12The inner wall of the support frame 101 is symmetrically fixed with pressure springs 9. The pressure springs 9 are made of elastic metal material. Their bottom ends are elastically abutted against the body of the cleaning bird rod 8, providing a continuous downward preload to the cleaning bird rod 8, ensuring that the cleaning bird rod 8 is always in contact with the isolation wheel 304 and that the cleaning effect is not diminished. Connecting parts 10 are fixed to the bottom sides of the pressure springs 9 by screws. Follower rings 11 are fixedly sleeved on the isolation wheels 304 on both sides of the middle of the drive shaft 301 and the driven shaft 302. The follower rings 11 rotate synchronously with the isolation wheels 304. The outer wall of the follower rings 11 is provided with push protrusions 12. The push protrusions 12 can rotate with the follower rings 11 and periodically and detachably abut against the connecting parts. On the 10, the connector 10 acts as a force transmission medium to receive the pushing force of the push protrusion 12. When the shredding mechanism 3 is running, the follower ring 11 rotates synchronously with the isolation wheel 304. The push protrusion 12 pushes the connector 10 once for each rotation, which in turn causes the pressure spring 9 to undergo elastic deformation and push the cleaning rod 8 upward. After the push protrusion 12 passes the connector 10, the pressure spring 9 resets under its own elastic force, causing the cleaning rod 8 to rebound downward. Each rebound will hit the isolation wheel 304 to generate vibration. The vibration generated by the knocking achieves the self-cleaning of the cleaning rod 8, avoiding the accumulation of scraped food residue at the end of the cleaning rod 8 under continuous use, thus ensuring the cleaning effect of the cleaning rod 8.

[0040] It should be noted that, in use, this auxiliary chewing device involves piling the food to be processed into the feed hopper 107, holding and turning the crank 503 of the hand-cranked drive mechanism 5. Power is transmitted via the drive shaft 301 to the meshing transmission gears 501, causing the driven shaft 302 to rotate synchronously in the opposite direction to the drive shaft 301. The shredding wheels 303, arranged alternately on the drive shaft 301 and driven shaft 302, mesh and rotate accordingly, simulating the tearing action of teeth to efficiently shred and refine the falling food. To adjust the degree of food compression, the adjusting wheel 604 of the adjustment mechanism 6 can be rotated, causing the eccentric shaft 601 to rotate. This, in turn, drives the adjusting shaft 402 along the connecting plate 602. The outer support plate 105 slides laterally through its groove, changing the distance between the adjusting shaft 402 and the fixed shaft 401, thereby adjusting the meshing gap of the compression wheel 403. After adjustment, the locking head 607 is engaged in the locking groove 605 under the action of the locking spring 608, completing the position locking. The shredded food falls naturally into the compression mechanism 4. Under the pressure of the food, the fixed shaft 401 and the adjusting shaft 402 rotate synchronously in opposite directions. The interlocking compression wheel 403 protrudes to squeeze and shape the loose food, forming a block or strip shape with uniform density and easy to swallow. The compressed food is discharged from the discharge port 106 at the bottom of the support frame 101 corresponding to the compression mechanism 4 for the user to eat.

[0041] When the shredding mechanism 3 is running, the isolation wheel 304 synchronously drives the follower ring 11 to rotate. The push protrusion 12 on the follower ring 11 periodically pushes the connecting piece 10 of the pressing spring 9, causing the pressing spring 9 to elastically deform and push the cleaning bird rod 8 upward. After the push protrusion 12 rotates past the connecting piece 10, the pressing spring 9 returns to its original position, causing the cleaning bird rod 8 to rebound downward and strike the isolation wheel 304. The reciprocating vibration and scraping of the cleaning bird rod 8 continuously cleans the food residue on the surface of the shredding wheel 303 and the isolation wheel 304, while achieving self-cleaning through vibration to prevent residue accumulation.

[0042] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
