Description

Technical Field

[0001] The present application relates to the technical field of medical service equipment, specifically to a medicine-dispensing mechanism of an elderly-assisting service robot. Background Art

[0002] Elderly service programs aim to provide various forms of support and assistance to seniors, improving their quality of life and social participation. These programs are typically initiated by governments, nonprofit organizations, community groups, or schools. By providing education, health, social, and psychological support, they help seniors solve practical problems in their daily lives while also upholding the traditional virtues of respecting the elderly and caring for the young. Elderly service robots are robotic devices that assist the elderly in their daily lives. Basic functions include regularly reminding them to take medication and providing medication delivery services.

[0003] In medication delivery services, the medicine retrieval mechanism is a key component of the elderly-assisting robot. Its primary function is to deliver stored medications to the elderly. Medication is typically stored in medicine boxes, which are placed in an insulated container on the elderly-assisting robot. Traditional medicine boxes typically open from the top, requiring the elderly to open and close them manually. However, for some elderly individuals with limited mobility, the complex structure of the medicine box mechanism can be a significant obstacle to medication retrieval. In unexpected situations, it can even be difficult to remove medication, potentially causing harm to the elderly.

[0004] Therefore, this application provides a medicine-taking mechanism for an elderly service robot to solve the above-mentioned problems. Utility Model Content

[0005] The present application provides a medicine dispensing mechanism for an elderly service robot, aiming to solve the problems raised in the background technology, such as the existing complex structure of the medicine box mechanism will bring huge obstacles to the dispensing of medicines, and in case of emergencies it may make it difficult to take out the medicines, causing harm to the elderly.

[0006] To achieve the above objectives, the present application provides the following technical solutions: a medicine dispensing mechanism of an elderly service robot, comprising a self-opening medicine dispensing mechanism installed in a heat preservation cavity provided on an heat preservation box:

[0007] The self-opening medicine taking mechanism includes a medicine box movably installed in the heat-insulating cavity and a lifting member fixedly installed in the heat-insulating cavity for supporting the medicine box to lift and lower for taking medicine. A medicine storage cavity with a side opening is provided in the medicine box. A box cover that is adapted to the opening of the medicine storage cavity is hingedly connected to the medicine box. A medicine storage hopper that is adapted to the inner wall of the medicine storage cavity is fixedly installed on a side wall of the box cover facing the medicine storage cavity. The inner bottom surface of the medicine storage hopper is designed to be a gradually rising slope from the side close to the inner wall of the box cover to the side away from the inner wall of the box cover. A spring sheet for rebounding the medicine storage hopper is fixedly installed on the surface opposite to the box cover in the medicine storage cavity. The outer wall of the box lid is blocked by the mouth of the insulation cavity and will gradually fit with the outer wall of the medicine box until it is closed. The tablets and capsules will roll back into the medicine hopper, completing the automatic taking and placing of medicines. During the process, the elderly do not need to open and close the medicine box manually, which greatly facilitates the use of the elderly and is safer and more reliable.

[0008] Preferably, in order to lift the medicine box up and down in the heat-insulating chamber, the lifting member includes a support base fixedly connected to the outer wall of the medicine box and a drive motor fixedly installed in the heat-insulating chamber for driving the support base to lift and lower. A rack extending into the heat-insulating chamber is fixedly installed at the bottom of the support base, and a driving gear fixedly connected to the output end of the drive motor is engaged on one side of the rack. When the drive motor is started, the driving gear rotates, and the driving gear rotates counterclockwise, driving the rack to move upward and pushing the medicine box on the support base to rise upward. The driving gear rotates clockwise, driving the rack to move downward, thereby driving the medicine box on the support base to move downward.

[0009] Preferably, to prevent the rack from deviating during movement and causing the medicine box to tilt, a driven gear is provided on the rack on the side opposite the driving gear, meshing with the driven gear. The driven gear is fixedly connected to a rotating shaft that is rotatably connected to the inner wall of the heat-insulating chamber. By providing a driven gear supported by the rotating shaft on the other side of the rack, when the driving gear pushes the rack up and down, the driven gear provides limited support to the rack from the other side, ensuring stable vertical movement of the medicine box within the heat-insulating chamber.

[0010] Preferably, to ensure the sealing of the medicine storage chamber, a sealing strip is fixedly mounted on the outer wall of the medicine box at the opening of the medicine storage chamber, which is adapted to the edge of the box lid. A sealing strip is fixed at the opening of the medicine storage chamber and contacts the box lid. When the box lid is closed, the sealing strip is pressed from the outside, thereby ensuring the sealing of the medicine box when stored in the insulated box and preventing the medicine from becoming ineffective.

[0011] Preferably, to facilitate the distinction of medications of different formulations, the inner wall of the medicine hopper is fixedly mounted with a plurality of evenly spaced dividing strips extending from one end proximal to the medicine hopper toward the edge of the inner sidewall of the lid. The dividing strips are arranged on the inner walls of the medicine hopper and lid, forming a plurality of L-shaped cavities for storing different tablets and capsules. Each different medication is stored in a separate cavity, thus preventing the problem of drugs being mixed and causing adhesion and contamination before use. The drugs roll out along the sidewalls of the dividing strips along the inclined surface of the bottom of the medicine hopper when the lid is tilted, and roll back along the dividing strips when the lid is closed vertically, without affecting each other, thereby ensuring longer-term storage of the drugs.

[0012] Preferably, to facilitate the elderly in taking medicine, a barrier that matches the lid is fixedly mounted on the top of the insulated box. The barrier is located exactly at the end of the lid when it is placed horizontally, blocking the end of the lid so that the medicine will roll out and hit the barrier. The top of the barrier is completely open, which is convenient for the elderly to take medicine without obstruction and easy to use.

[0013] Preferably, to ensure that the lid can naturally tilt downward, a notch is provided on the outer wall of the lid at one end away from the hinged connection with the medicine box, and a counterweight is inserted into the notch. By providing the counterweight on the outer wall of the upper end of the lid, and inserting the counterweight into the notch, when the medicine box is fully raised to the top of the heat preservation cavity, the lid on the side of the medicine box is unobstructed and will naturally tilt downward under the force of gravity caused by the downward tilt of the counterweight, ensuring that the lid automatically opens.

[0014] When taking medicine, the medicine dispensing mechanism pushes the medicine box upward out of the insulation cavity through the lifting member until the bottom of the medicine box is completely flush with the top surface of the insulation box, and the laterally arranged box cover is not hindered by the side wall of the insulation cavity. The spring sheet pushes the bottom of the medicine storage hopper upward, so that the box cover leads the medicine storage hopper toward the top surface of the insulation box to avoid tilting upward, until it is in horizontal contact with the top surface of the insulation box. The round tablets and capsules will roll onto the box cover along the inclined surface of the medicine storage hopper, and the elderly can take them directly. After taking them, the medicine box is pulled down back into the insulation cavity by the lifting member, and the outer wall of the box cover is blocked by the cavity opening of the insulation cavity and will gradually fit with the outer wall of the medicine box until it is closed. The tablets and capsules roll back into the medicine storage hopper, completing the work of automatically taking and placing medicines. During the process, the elderly do not need to open and close the medicine box manually, which greatly facilitates the use of the elderly and is safer and more reliable.

[0015] The medicine dispensing mechanism is provided with a partition strip on the inner wall of the medicine storage hopper and the box cover, so that a plurality of L-shaped cavities for storing different tablets and capsules are formed on the medicine storage hopper and the box cover. Each different medicine is stored in a different cavity, avoiding the problem of adhesion and mutual contamination of medicines before use caused by mixing. The medicines roll out along the side wall of the partition strip along the inclined surface of the bottom of the medicine storage hopper when the box cover is tilted, and roll back along the partition strip when the box cover is closed vertically, without affecting each other, ensuring that the medicines are preserved for a longer period of time.

[0021] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0022] Example 1

[0023] This embodiment provides a medicine taking mechanism for an elderly service robot, such as Figure 1-3 As shown, the medicine dispensing mechanism includes a self-opening medicine dispensing mechanism 3 installed in a heat preservation cavity 2 opened on a heat preservation box 1:

[0024] The self-opening medicine taking mechanism 3 includes a medicine box 31 movably installed in the heat-insulating cavity 2 and a lifting member 32 fixedly installed in the heat-insulating cavity 2 for supporting the medicine box 31 to lift and lower for taking medicine. A medicine storage cavity 33 with a side opening is provided in the medicine box 31. A box cover 34 that is adapted to the opening of the medicine storage cavity 33 is hinged on the medicine box 31. A medicine storage hopper 35 that is adapted to the inner wall of the medicine storage cavity 33 is fixedly installed on a side wall of the box cover 34 facing the inside of the medicine storage cavity 33. The inner bottom surface of the medicine storage hopper 35 is designed to be a gradually rising slope from the side close to the inner wall of the box cover 34 to the side away from the inner wall of the box cover 34. A spring sheet 36 for rebounding the medicine storage hopper 35 is fixedly installed on the surface opposite to the box cover 34 in the medicine storage cavity 33.

[0025] The medicine box 31 is automatically taken out of the medicine storage hopper 35 by the lifting member 32, and the medicine box 31 is pushed out of the heat preservation cavity 2 by the lifting member 32 until the bottom of the medicine box 31 is completely flush with the top surface of the heat preservation box 1. The laterally arranged box cover 34 is not hindered by the side walls of the heat preservation cavity 2. The spring sheet 36 pushes the bottom of the medicine storage hopper 35 upward, so that the box cover 34 and the medicine storage hopper 35 are prevented from tilting upward, until they are in horizontal contact with the top surface of the heat preservation box 1. The round tablets and capsules will roll onto the box cover 34 along the inclined surface of the medicine storage hopper 35, and the elderly can take them directly. After taking out, the medicine box 31 is pulled down back into the heat preservation cavity 2 by the lifting member 32, and the outer wall of the box cover 34 is blocked by the cavity opening of the heat preservation cavity 2 and will gradually fit the outer wall of the medicine box 31 until it is closed. The tablets and capsules roll back into the medicine storage hopper 35, completing the work of automatically taking out and putting out the medicine. During the process, the elderly do not need to open and close the medicine box 31 manually, which greatly facilitates the use of the elderly and is safer and more reliable.

[0026] Specifically, the lifting member 32 includes a support seat 321 fixedly connected to the outer wall of the medicine box 31 and a drive motor 322 fixedly installed in the insulation cavity 2 for driving the support seat 321 to rise and fall. A rack 323 extending into the insulation cavity 2 is fixedly installed at the bottom of the support seat 321, and a driving gear 324 fixedly connected to the output end of the drive motor 322 is meshed on one side of the rack 323.

[0027] When in use, the driving motor 322 is started to drive the driving gear 324 to rotate. The driving gear 324 rotates counterclockwise, drives the rack 323 to move upward, and pushes the medicine box 31 on the support base 321 to rise upward. The driving gear 324 rotates clockwise, drives the rack 323 to move downward, thereby driving the medicine box 31 on the support base 321 to move downward.

[0028] More specifically, a driven gear 325 is provided on the rack 323 on a side opposite to the driving gear 324 , and a rotating shaft 326 is fixedly connected to the driven gear 325 and is rotatably connected to the inner wall of the heat preservation cavity 2 .

[0029] When in use, a driven gear 325 supported by a rotating shaft 326 is provided on the other side of the rack 323. When the driving gear 324 pushes the rack 323 up and down, the driven gear 325 limits the support of the rack 323 from the other side to ensure that the medicine box 31 moves up and down stably in the insulation cavity 2.

[0030] Furthermore, a sealing strip 37 is fixedly mounted on the outer wall of the medicine box 31 at the opening of the medicine storage cavity 33, which is adapted to the edge of the box lid 34. During use, the sealing strip 37 is fixed at the opening of the medicine storage cavity 33 and contacts the box lid 34. When the box lid 34 is closed, it presses against the sealing strip 37 from the outside, thereby ensuring the sealing of the medicine box 31 when stored in the insulated box 1 and preventing the medicine from becoming ineffective.

[0031] Furthermore, a plurality of evenly distributed dividing strips 38 are fixedly mounted on the inner wall of the medicine storage hopper 35 and extend toward the inner wall of the box cover 34 from one end close to the medicine storage hopper 35 toward the end surface away from the medicine storage hopper 35 to the edge.

[0032] When in use, a partition strip 38 is provided on the inner wall of the medicine storage hopper 35 and the box cover 34, so that a plurality of L-shaped cavities for storing different tablets and capsules are formed on the medicine storage hopper 35 and the box cover 34. Each different medicine is stored in one cavity, so as to avoid the problem of adhesion and mutual contamination of the medicines before use caused by mixing the medicines. The medicines roll out along the side wall of the partition strip 38 along the inclined surface of the bottom of the medicine storage hopper 35 when the box cover 34 is tilted, and roll back along the partition strip 38 when the box cover 34 is vertically closed, without affecting each other, thereby ensuring that the medicines are preserved for a longer period of time.

[0033] Among them, a fence 39 is fixedly installed on the top of the insulated box 1 to match the box cover 34. When in use, the fence 39 is set exactly at the end of the box cover 34 when it is placed horizontally, blocking the end of the box cover 34 so that the medicine rolls out and hits the fence 39. The top of the fence 39 is a completely normally open design, which is convenient for reminding the elderly to take medicine without obstruction and easy to use.

[0034] Secondly, a notch 310 is formed on the outer wall of the lid 34 at one end away from the hinged connection with the medicine box 31, and a counterweight 311 is inserted into the notch 310. During use, by installing the counterweight 311 on the outer wall of the upper end of the lid 34 and inserting it into the notch 310, when the medicine box 31 is fully raised to the top of the heat-insulating cavity 2, the lid 34 on the side of the medicine box 31 is free of obstruction and will naturally tilt downward under the force of gravity caused by the counterweight 311, ensuring that the lid 34 automatically opens.

[0035] The above is only a preferred specific implementation method of the present application, but the scope of protection of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and concept of the present application within the technical scope disclosed in the present application, and they should be covered by the scope of protection of the present application.
