Description

Technical Field

[0001] This utility model relates to the field of dental impressions, and in particular to a water supply device for a mixer and a mixer. Background Technology

[0002] When treating patients, dentists need to obtain dental models for orthodontic treatment, restorations, and other procedures. The process of obtaining these models is called dental impression taking, or simply taking a dental impression. Commonly used dental impression materials are alginate and plaster. Currently, mixing is usually done manually. Different materials require different water-to-powder ratios, and manual mixing makes it difficult to control the water volume, leading to reduced performance of the resulting impression material. To address these issues, devices using electric pumps and solenoid valves to control water supply have been developed. However, this requires integrating these components into a mixer, which necessitates complex circuitry to control the coordinated operation of the mixer, pump, and valves. This complicates the mixer's structure, making it difficult to maintain and increasing operating costs. Utility Model Content

[0032] Examples of embodiments of this utility model Figures 1 to 14As shown, a water supply device for a mixer includes a mounting frame 1. A first water tank 2 with one-way inlet and one-way outlet is mounted on the mounting frame 1. An inlet pipe 18 and an outlet pipe 19, both connected to the first water tank 2, are provided. One-way valves 180 are installed in both the inlet and outlet pipes 18 and 19, respectively. Any existing one-way valve can be used, but they are installed in opposite directions within the inlet and outlet pipes 18 and 19. That is, the one-way valve 180 in the inlet pipe 18 can only allow water to enter but not exit, and the one-way valve 180 in the outlet pipe 19 can only allow water to exit but not enter. This prevents water from flowing out of the inlet pipe 18 during outlet or vice versa. The water flows out through pipe 19; at this time, a water storage tank 17 for supplying water to the first water tank 2 can also be installed on the mounting frame 11. The installation of the water storage tank 17 facilitates water use. At this time, a water pipe is installed at the inlet pipe 18 of the first water tank 2, and then the water pipe is inserted into the water storage tank 17. The water pipe extends to the lower part of the water storage tank 17 or extends to the inner bottom surface of the water storage tank 17; a handle 5 is pivotally connected to the mounting frame 1. The handle 5 is pivotally connected to the first linkage mechanism 6 and the second linkage mechanism 7 in sequence at intervals along the direction away from the pivot position of the mounting frame 1. The axis of rotation of the handle 5 relative to the mounting frame 1, the first linkage mechanism 6 and the second linkage mechanism 7 are in the same direction. The handle 5 is pivotally connected to the mounting frame 1 at the right end, such as Figure 3 and Figure 8 As shown, a first linkage mechanism 6 and a second linkage mechanism 7 are arranged sequentially from right to left on the bottom surface of the handle 5. The axis of rotation of the handle 5 relative to the mounting bracket 1, the first linkage mechanism 6, and the second linkage mechanism 7 are all in the front-back direction. Figure 2 and Figure 4 As shown, the end of the second linkage mechanism 7 furthest from the handle 5 is pivotally connected to a piston 70 that is movable up and down and is installed in the first water tank 2. When the piston 70 moves upward in the first water tank 2, it forms a suction state, and the water inlet pipe 18 is connected to the water supply device. The one-way valve 180 in the water inlet pipe 18 is opened, while the one-way valve 180 in the water outlet pipe 19 is not opened, and water is drawn into the first water tank 2 from the water inlet pipe 18. When the piston 70 moves downward, it applies pressure to the water in the first water tank 2, and the one-way valve 180 in the water outlet pipe 19 opens, while the one-way valve 180 in the water inlet pipe 18 closes, and water flows out from the water outlet pipe 19. At this time, the first water tank 2 is configured as a water tank with a circular cross-section of the internal water storage space, and the piston 70 is correspondingly configured as a cylinder. The piston 70 and the handle 5 are pivotally connected through the second linkage mechanism 7, as shown in the figure. Figure 2 , Figures 4 to 8 As shown, the second linkage mechanism 7 is configured as a connecting rod, with its two ends pivotally connected to the bottom surface of the handle 5 and the top of the piston 70, respectively. The first linkage mechanism 6 and the second linkage mechanism 7 are then positioned on opposite sides of the same surface of the handle 5. Figure 8 and Figure 9As shown, the first linkage mechanism 6 includes a first link 61, a second link 62, and a V-shaped adapter rod 63. The first link 61 is vertically arranged, while the second link 62 and the adapter rod 63 are horizontally arranged. The two ends of the first link 61 are pivotally connected to the bottom surface of the handle 5 and one end of the adapter rod 63, respectively. One end of the second link 62 is pivotally connected to the other end of the adapter rod 63, and the other end of the second link 63 is movably connected to the limit adjustment mechanism 8. The opening of the V-shaped structure of the adapter rod 63 is set downwards, which is the opening of the second link 61. The other end of the 2 is provided with a first slot 60, and a rotating shaft 64 is provided at the top corner of the adapter rod 63. The rotating shaft 64 can be fixedly mounted on the mounting bracket 1, and the adapter rod 64 is sleeved on the rotating shaft 64 and rotates relative to the rotating shaft 64. Alternatively, the adapter rod 63 and the rotating shaft 64 can be fixedly connected, and the rotating shaft 64 can be pivotally connected to the mounting bracket 1. The second connecting rod 62 can also be composed of a front rod 620 and a rear rod 621. A middle connecting rod is provided between the front rod 620 and the rear rod 621, with corresponding threaded connections at both ends to the front rod 620 and the rear rod 621. The intermediate rod 622 has a first slot 60 on the front rod 620, meaning that threaded holes are provided on the rear end face of the front rod 620 and the front end face of the rear rod 621. Both ends of the intermediate rod 622 have external threads. The second connecting rod 62 is then covered with an inverted U-shaped top cover, which is mounted on the mounting bracket 1. The second connecting rod 62 moves within the U-shaped opening of the top cover, which acts as a guide. A limit adjustment mechanism 8 is provided at the end of the first connecting rod mechanism 6 furthest from the handle 5 to adjust the range of motion of the first connecting rod mechanism 6. The limit adjustment mechanism 8 and the handle 5 are located at both ends of the first linkage mechanism 6. The limit adjustment mechanism 8 is used to adjust the range of motion of the first linkage mechanism 6, which in turn adjusts the distance the piston 70 moves up and down in the first water tank 2, thus adjusting the suction force on the water in the first water tank 2 and consequently adjusting the amount of water entering the first water tank 2. This allows for adjustment based on the water volume required for the dental mold material to be mixed, achieving a standardized powder-to-water ratio and ensuring consistent performance of the dental mold material in each mix. This structure utilizes a purely mechanical method to adjust the water volume, simplifying the structure and reducing operating costs.

[0033] Further improvements, such as Figure 6 , Figure 8 and Figure 9As shown, the first linkage mechanism 6 has a first slot 60 at the other end opposite to the handle 5. The limiting adjustment mechanism 8 includes a locking member 80 that can be movably locked in the first slot 60, and a first adjusting member 81 that adjusts the locking member 80 to lock or disengage from the first slot 60. The first adjusting member 81 pushes the locking member 80 to lock it in the first slot 60, and then the first adjusting member 81 pushes in the opposite direction to pull the locking member 80 out of the first slot 60, so that the locking member 80 and the first slot 60 are disengaged. When the locking member 80 and the first slot 60 are disengaged, when the first linkage mechanism 6 moves to its maximum range of motion, a certain water inlet is formed for the first water tank 2. When the locking member 80 is locked into the first slot 60, the locking member 80 reduces the maximum range of motion of the first linkage mechanism 6 and limits it to another certain value, so the first water tank 2 forms another certain water inlet. For the engaging component 80, the engaging component 80 is a flat U-shaped engaging component. If it is set as a round-bottomed U-shaped structure, there will be no jamming between it and the adjusting component protrusion 810. The engaging component 80 has an extension arm 800 extending from one end to engage with the first slot 60. The first adjusting component 81 has an adjusting component protrusion 810 extending from it into the U-shaped opening of the engaging component 80. The first adjusting component 81 is a flat plate-like structure. At this time, the engaging component 80 is rotatably set on the top surface of the mounting base 10. The movement of the first adjusting component 81 causes the adjusting component protrusion 810 to push the two ends of the U-shaped structure of the engaging component 80 accordingly, so that the engaging component 80 rotates towards the first slot 60 or rotates away from the first slot 60 to achieve engagement and disengagement. In order to facilitate the engagement of the engaging component 80 with the first slot 60, the length of the end of the engaging component 80 with the extension arm 800 is less than the length of the other end of the engaging component 80.

[0034] Further improvements, such as Figure 1 As shown, the mounting frame 1 includes a mounting base 10 and a mounting bracket 11 connected to the mounting base 10; a limit adjustment mechanism 8 is disposed on the mounting base 10, and a handle 5, a first water tank 2, and a first linkage mechanism 6 are all disposed on the mounting bracket; the mounting base 10 is used to connect a container containing dental mold material, the mounting bracket is mounted on the outer wall of the mounting base, and a base is provided at the bottom end of the mounting bracket; as shown Figures 1 to 11 As shown in the diagram, at this point, an annular wall 101 can be extended downwards from the bottom edge of the mounting base 10, forming an inverted barrel-shaped structure. The container holding the dental mold material can then be installed inside the barrel-shaped structure. Figure 9As shown, the first slot 60 is located on the side wall of the first linkage mechanism 6 opposite to the handle 5 and perpendicular to the top surface of the mounting base 10. The first slot 60 is located on the side of the front rod 620. The engaging member 80 is rotatably mounted on the top surface of the mounting base 1. The engaging member 80 is located adjacent to the opening of the first slot 60. The engaging member 80 extends a protrusion at the bottom end of the U-shaped structure. The engaging member 80 is pivotally connected to the top surface of the mounting base 10 at the protrusion. The first adjusting member 81 is slidably mounted on the top surface of the mounting base 10 and adjusts the engagement between the engaging member 80 and the first slot 60. The first adjusting member 81 is located below the engaging member 80 and the adjusting member protrusion 810 is located below the engaging member 80. As the first adjusting member 81 slides towards the first slot 60 on the top surface of the mounting base 10 within the U-shaped opening, the adjusting member protrusion 810 also moves in the same direction. At this time, the adjusting member protrusion 810 applies a force to the end of the engaging member 80 near the first slot 60, pushing the engaging member 80 to rotate. The rotation of the engaging member 80 causes the extension arm 800 on the engaging member 80 to engage in the first slot 60, limiting the movement of the first linkage mechanism 6. Similarly, when the first adjusting member 81 moves away from the first slot 60, it pulls the extension arm 800 on the engaging member 80 out of the first slot 60, and the engaging member 80 and the first linkage mechanism 6 disengage. The sliding structure of the first adjusting member 81 on the mounting base 10 is such that the first adjusting member 81 is set as an arc-shaped strip, and an arc-shaped groove 812 is set on the bottom surface of the first adjusting member 81 along the arc direction. An arc-shaped protrusion 102 that matches and engages in the groove 812 is set on the top surface of the mounting base 10. The arc-shaped protrusion 102 constitutes the slide rail for the first adjusting member 81 to slide.

[0035] Further improvements, such as Figure 1 , Figure 2 , Figure 10 and Figure 12 As shown, the mounting base 10 is provided with an upper shell 9, and the limit adjustment mechanism 8 is disposed inside the upper shell 9. An avoidance notch 90 is provided on the side wall of the upper shell 9. The avoidance notch 90 is used to avoid the connection between the first linkage mechanism 6 and the engaging member 80, as well as the water outlet of the first water tank 2. At this time, the upper shell 9 can be mounted on the mounting bracket 11 at the edge of the avoidance notch 90, and then the mounting base 10 is connected to the mounting bracket 11 through the upper shell 9, or both the upper shell 9 and the mounting base 10 can be connected to the mounting bracket 11; for example... Figure 6 and Figure 8As shown, the top surface of the mounting base 10 is provided with a strip-shaped first through hole 100 at the position corresponding to the first adjusting member 81. The first adjusting member 81 is provided with a first adjusting arm 811 that can move within the first through hole 100. The first through hole 100 passes through the upper and lower surfaces of the mounting base 10. In this way, the first adjusting member 81 can be pushed to slide on the top surface of the mounting base 10 by pushing the first adjusting arm 811, which is convenient for operation and avoids the influence of other components inside the upper shell 9. If the first adjusting arm 811 is located at the bottom of the groove 812 on the bottom surface of the first adjusting member 81, a strip-shaped raised through hole connected to the first through hole 100 is provided on the arc-shaped protrusion 102. The first adjusting arm 811 passes through the raised through hole and extends into the first through hole 100.

[0036] A type of mixer, such as Figures 1 to 3 As shown, using the water supply device described above, a drive motor 12 and a first micro switch 13 are also installed on the mounting bracket 11. The output shaft of the drive motor 12 can be directly connected to the stirring head to drive the stirring head for stirring, or a connector 4 for connecting the stirring head can be connected to the output shaft of the drive motor 12. Driving the connector 4 to rotate will drive the stirring head connected to the connector 4 to rotate. The drive motor 12 is installed on the top of the mounting base 10 with screws. The output shaft of the drive motor 12 passes through the bottom of the mounting base 10 and is connected to the top of the connector 4. The drive motor 12 drives the connector 4 to rotate, and the rotation of the connector 4 drives the stirring head connected to the lower end of the connector 4 to rotate. The stirring head can be detachably connected to the connector, so different stirring heads can be used according to the usage requirements; limit adjustment The joint mechanism 8 is in contact with the first micro switch 13, which is located on the outside of the second water tank 3. The first micro switch 13 indicates that the container containing the dental membrane material has been installed in place on the mounting base 10. After that, the drive motor 12 can be started to stir. When the first micro switch 13 is not turned on, the drive motor 12 cannot be started. When the first adjusting member 81 of the limit adjusting mechanism 8 slides on the mounting base 10 towards the first micro switch 13, it touches the first micro switch 13 and turns on the first micro switch 13. When it slides away from the first micro switch 13, it turns off the first micro switch 13. Multiple connecting parts 41 for connecting the stirring head are arranged at equal intervals along the circumference of the connecting part 4 at the same height on the outer wall of the lower part of the connecting part 4. The connecting parts 41 facilitate the disassembly and assembly of the stirring head. Figure 11 As shown, the top of the stirring head is provided with a ring that fits onto the connector 4. A groove is provided on the inner wall of the ring that matches and engages with the connector locking block 41. The stirring head and connector 4 are connected by the engagement of the connector locking block 41 and the groove. The drive motor 12 and the first micro switch 13 are both located on the top surface of the mounting base 10. To adapt to the needs of stirring different dental mold materials, such as… Figure 3 As shown, two first microswitches 13 are provided. A first adjusting member 81 is connected to a contact member 82 that movably abuts against one of the two first microswitches 13. The first adjusting member 81 and one first microswitch 13 correspond to the stirring of one dental mold material. A second adjusting member 14 is also slidably provided on the mounting base 10. The second adjusting member 14 movably abuts against the other of the two first microswitches 13. The second adjusting member 14 and the other first microswitch 13 correspond to the stirring of another dental mold material. The sliding structure of the second adjusting member 14 on the mounting base 10 is the same as the sliding structure of the first adjusting member 81 on the mounting base 10. Correspondingly, a strip-shaped second through hole 140 is provided on the mounting base 10 at the position corresponding to the second adjusting member 14. A second adjusting arm 141 that can move within the second through hole 140 is provided on the second adjusting member 14. Different mounting base slots 15 are provided on the bottom surface of the mounting base 10 at the positions corresponding to the first through hole 100 and the second through hole 140.

[0037] For the mounting bracket slot 15, one mounting bracket slot 15 corresponds to one type of dental mold material mixing, such as... Figure 11 As shown, the mounting base slot 15 is configured with different shaped engagement structures; in practical applications, the appropriate amount is weighed according to the different dental mold materials, and then different dental mold materials are placed in different material containers, such as... Figure 15As shown, the material hopper is equipped with a top cover, and a countersunk circular material hopper through hole is provided at the center of the top surface of the top cover. A stirring head is provided inside the material hopper, and the top of the stirring head is a ring that can rotate within the material hopper through hole. The inner wall of the ring is provided with a structure that matches and connects with the connecting piece 40 on the connecting piece 4. At the same time, three top cover blocks extend at equal intervals along the circumference of the top edge of the top cover. The top cover blocks can be set into a strip structure or a U-shaped structure according to different dental membrane materials. At this time, two different mounting base slots 15 are provided at equal intervals on the inner wall of the annular wall 101 extending downward from the bottom edge of the mounting base 10. Both types of mounting base slots 15 are extended upward from the inner wall of the annular wall. The protruding sidewall protrusion is formed by the distance between it and the bottom surface of the mounting base 10. Each type of mounting base slot 15 has three slots. One type has a stop 152 in front of the mounting base slot 15 that can match the U-shaped opening of the top cover block that is inserted into the U-shaped structure. This can be called the first mounting base slot 150. The other type is a structure without a stop in front of the mounting base slot 15. This can be called the second mounting base slot 151. The two types of mounting base slots 15 are arranged alternately. That is, there is one and only one second mounting base slot 151 between two adjacent first mounting base slots 150. At this time, the front end of the slot of the first mounting base slot 150 and the second mounting base slot 151 in front of it are connected. The distance between the ends of the slots is greater than the distance between the end of the first mounting slot 150 and the front end of the second mounting slot 151. Simultaneously, the length of the U-shaped top cover block is approximately equal to the distance between the front end of the first mounting slot 150 and the end of the second mounting slot 151. The distances from the stop block 152 to the front end of the first mounting slot 150 and to the end of the second mounting slot 151 are both less than the length of the strip-shaped top cover block. Thus, the U-shaped top cover block can enter and engage between the front end of the first mounting slot 150 and the end of the second mounting slot 151. In the first mounting slot 150, the strip-shaped top cover block cannot be inserted from the position due to the presence of the stop block 152. Similarly, the U-shaped top cover block cannot be inserted from the tail end of the first mounting slot 150 and the front end of the second mounting slot 151 into the second mounting slot 151. The strip-shaped top cover block can be inserted from this position into the second mounting slot 151. Thus, the first mounting slot 150 and the U-shaped top cover block correspond to one dental mold material, and the second mounting slot 151 and the strip-shaped top cover block correspond to another dental diaphragm material. The dental diaphragm material used can be automatically identified by inserting the material container.The first through hole 100 corresponds to any one of the three first mounting base slots 150. The lower end of the first adjusting arm 811 extends through the first through hole 100 and into the first mounting base slot 150. When the U-shaped top cover block is engaged in the first mounting base slot 150, the first adjusting arm 811 is pushed, thereby activating the corresponding first micro switch 13. Similarly, the second through hole 140 corresponds to any one of the three second mounting base slots 151. The lower end of the second adjusting arm 141 extends through the second through hole 140 and into the second mounting base slot 151. When the strip-shaped top cover block is engaged in the second mounting base slot 151, the second adjusting arm 141 is pushed, thereby activating the corresponding first micro switch. (The last sentence appears to be incomplete and possibly a fragment from another context.) Figure 2 As shown, a second micro switch 16 for controlling the drive motor 12 is also provided on the mounting bracket 11, which can be in contact with the handle 5. When the handle 5 is pressed on the second micro switch 16, the second micro switch 16 is turned on, which means that the handle 5 is pressed in place and the drive motor 12 can be started to stir. When the second micro switch 16 is turned off, the drive motor 12 cannot be started, ensuring the safety of use.

[0038] The mounting base 10 is also provided with a water outlet channel 103 connected to the first water tank 2. When the material tank is equipped with a top cover, the top surface of the material tank top cover is designed to be gradually concave from the edge to the center. A water inlet hole is provided on the top cover for water inlet. Water flows to the top cover through the water outlet channel 103, and then flows through the water inlet hole into the material tank. For the water outlet channel 103, one option is to set it on the top surface of the mounting base 10 at a position near the output shaft of the drive motor 12. Figure 13 and Figure 14 As shown in the diagram; another type is where the water outlet channel 103 is a second water tank 3 mounted on the mounting base 10, as shown in the diagram. Figures 1 to 5 , Figure 8 and Figure 10As shown, the second water tank 3 is connected to the first water tank 2 and is supplied with water through the first water tank 2; the second water tank 3 is connected to the outlet pipe 19 of the first water tank 2 through a water pipe; the connector 4 is sealed to the bottom surface of the second water tank 3 and can rotate relative to the second water tank 3. The lower part of the connector 4 is outside the second water tank 3. The connector 4 is a cylindrical structure with a sealed top. The second water tank 3 has an inverted T-shaped structure with an open bottom. The top of the second water tank 3 has a top through hole 30 coaxial with the connector 4. The drive motor 12 can be positioned directly above the second water tank 3. The output shaft of the drive motor 12 extends into the second water tank 3 through the top through hole 30 and is connected to the top of the connector 4. An extension pipe 31 extends from the upper part of the outer wall of the second water tank 3 and communicates with the interior of the second water tank 3. The water pipe connected to the outlet pipe 29 of the first water tank 2 is connected to this extension pipe 31. A connector protrusion 42 extends radially outward around the lower part of the outer wall of the connector 4. The connector 4 is inserted into the second water tank 3 from the bottom opening, and the connector protrusion 42 abuts against the second water tank. The bottom of the second water tank 3 is sealed on the open end face. At this time, a sealing element 43 is fitted on the top surface of the connector 4 protrusion 42, which corresponds to the horizontal part of the inverted T-shaped structure of the second water tank 3. The bottom of the second water tank 3 is sealed by the sealing element 43 and the connector 4, while the connector 4 can rotate inside the second water tank 3. The sealing element 43 can be a sealing ring or an oil seal. The connector 4 is provided with a connector through hole 40 on the side wall inside the second water tank 3. In this way, the water entering the second water tank 3 gradually rises inside the second water tank 3 until it rises to the connector through hole 40. When the water flows into the connector 4 through the through hole 40, it flows out from the bottom of the connector 4 and into the container containing the dental mold material located at the bottom of the connector 4. The stirring head for stirring the dental mold material is connected to the connector 4. As the drive motor 12 drives the connector 4 to rotate, the connector 4 rotates with the stirring head to stir. Correspondingly, the drive motor 12 is mounted on the top surface of the mounting base 10 and above the second water tank 3. The first micro switch 13 is located on the outside of the second water tank 3, and the two first micro switches 13 are spaced apart along the circumference of the second water tank 3. When the water outlet channel is located near the output shaft of the drive motor 12, the number of slots on the ring of the stirring head is more than the number of slots 41 on the connector. The extra slots can act as water inlets for the material tank. Before the drive motor 12 starts, water flows from the water outlet channel to the top surface of the material tank, and then flows into the material tank from the extra slots.

[0039] Further improvements, such as Figure 1As shown, a vibration seat 110 is provided on the mounting bracket 1. The vibration seat 110 is placed on the base of the mounting bracket 11, and a connecting plate extending from the base is provided on the base of the mounting bracket 11. A vibration base with an internal cavity is provided at the end of the connecting plate away from the mounting bracket 11. A vibration motor is provided on the top wall of the vibration base. Two grippers are provided on the left and right sides of the front of the top face of the vibration base for limiting rotation. The structure is that a rotating column is provided on the top surface of the vibration base, and the rotation of the grippers is sleeved on the rotating column. At the same time, a positioning groove and a positioning protrusion that can be matched and engaged are provided between the rotating column and the grippers. When the grippers rotate to a certain position, the positioning protrusion engages in the positioning groove to limit the rotation of the grippers. In use, the dental mold tray is placed on the top of the vibration box. The handle of the dental mold tray is held by the two grippers to fix the dental mold tray on the vibration box. Then, the vibration motor is started to make the dental mold tray vibrate. The dental film material coated on the dental mold tray will remove air bubbles during vibration and be evenly spread on the dental mold tray.
