Description

Technical Field

[0001] This utility model relates to the field of dental impression equipment, and in particular to an automated mixer for mixing dental impression materials. Background Technology

[0002] When making dental molds, it is usually necessary to mix the mold material and water. Current technology involves manually mixing the mold material and water. Commonly used mold materials are plaster or alginate, and their water-to-mold ratios differ. Manual mixing introduces the issue of varying water-to-mold ratios. With a fixed amount of mold material, adding too little or too much water will not meet the mold-making requirements, necessitating further adjustments and adding to the process. This means that manual mixing requires a high level of experience. Furthermore, the mixing ratio of mold material and water will vary depending on the operator and even the same operator at different times, making it impossible to achieve a uniform ratio and resulting in molds that do not meet consistent standards.

Therefore, they should not be construed as limitations on the present invention.

[0033] Examples of embodiments of this utility model Figures 1 to 16As shown, an automated mixer for mixing dental mold materials includes a mounting frame 1, on which a water supply mechanism 2 is mounted, multiple first water tanks 3 (each with adjustable water volume and connected to an outlet pipe) connected to the water supply mechanism 2, and a drive motor 5. The water supply mechanism 2 and the first water tanks 3 are connected through an inlet pipe (not shown) of the first water tanks 3. The water from the first water tanks 3 is discharged directly through an outlet pipe (not shown) or connected to other components. Both the inlet and outlet pipes are connected using existing flexible hoses. The outlet pipe of the first water tanks 3 can directly deliver water to a storage container 9 containing dental mold materials, or an intermediate medium can be connected between the outlet pipe and the storage container 9 to ultimately deliver the water to the storage container 9. The first water tanks 3 can be adjusted to store different amounts of water according to usage requirements, thus meeting the mixing needs of different types of dental mold materials. The water required for mixing is fixed for a given dental model material with a specific water-to-powder ratio. Therefore, the volume of the first water tank 3 needs to be adjusted to match the amount of water required for mixing the dental model material. Since the amount of dental model powder weighed each time is fixed, the amount of water added is also fixed, achieving quantitative water usage and consistent mixing of the dental model material. Multiple first water tanks 3 correspond to the mixing of various dental model materials, eliminating the need to change equipment when mixing different materials, making it convenient to use. For example, setting two first water tanks 3 corresponds to conventional plaster and alginate dental model materials. The water supply mechanism 2 supplies water to the first water tank 3. The output shaft of the drive motor 5 can be directly connected to the stirring head to drive the stirring head for mixing, or a connector 8 for connecting the stirring head can be connected to the output shaft of the drive motor 5, driving the rotation of the connector 8 to rotate the stirring head connected to the connector 8 for mixing.The first water tank 3 regulates the amount of water it can store by either an electronic water level control switch 30 or a sealing plug 6 installed within it. In other words, the electronic water level control switch 30 or the sealing plug 6 controls the water level in the first water tank 3. Depending on the usage requirements, the electronic water level control switch 30 or the sealing plug 6 can be positioned at different locations within the first water tank 3. When the water level in the first water tank 3 reaches the set storage capacity, the electronic water level control switch 30 or the sealing plug 6 stops the water supply to the first water tank 3. The sealing plug 6 is installed in the first water tank 3 to seal the water supply according to different water consumption needs. The sealing plug 6 can also slide up and down within the first water tank 3 and be installed in a sealed manner, corresponding to the height inside. The position of the sealing plug 6 within the first water tank 3 can be easily adjusted by sliding it up and down. For example, if the first water tank 3 is designed as a cylindrical structure, a pull rod can be threaded onto the top of the sealing plug 6 to pull it up and down within the first water tank 3. After determining the height of the sealing plug 6 within the first water tank 3, the pull rod can be removed, thus adjusting the size of the water storage space in the first water tank 3, i.e., adjusting the water volume. A sealing ring is fitted onto the outer wall of the sealing plug 6 to achieve a seal. Regarding the structure of the sealing plug 6, for example… Figure 8 , Figure 10 and Figure 11 As shown, the sealing plug 6 has a conical sealing plug through-hole 60 at its center. This through-hole 60 allows air to escape from the first water tank 3 when water enters. A spherical sealing float 61 is installed inside the sealing plug through-hole 60, which floats and seals the through-hole 60. The conical structure of the sealing plug through-hole 60 means that its upper diameter is smaller than its lower diameter, while the diameter of the sealing float 61 is within the conical range. Between the upper and lower diameters of the sealing through-hole 60, the sealing float 61 will float upwards towards the upper end of the sealing through-hole 60 when water enters the first water tank 3. After floating to a certain height, the sealing float 61 will be tangent to the hole wall of the sealing through-hole 60 in the circumferential direction, thereby sealing the sealing through-hole 60. The first water tank 3 is also equipped with a water valve 7, which is used to control the inflow and outflow of water in the first water tank 3. Each first water tank 3 is equipped with a water valve 7.

[0034] A further improvement is that the water valve 7 is a solenoid valve or a mechanical valve installed on the first water tank 3, such as... Figure 1 The image shown is of a solenoid valve. Figure 7 , Figure 8 and Figure 12The valve shown is a mechanical valve, meaning that water valve 7 employs two different structures: one is an electrically controlled solenoid valve (any existing solenoid valve can be used), and the other is a valve controlled by a mechanical structure. The mechanical valve includes a bottom-closed cylinder 70, a lever 71 mounted on the lower outer wall of the cylinder 70, and a cylinder through-hole 700 on the cylinder 70. A cylindrical connector 31 extends from the bottom of the first water tank 3, with a diameter smaller than that of the first water tank 3. The cylinder 70 is rotatably and sealed within the connector 31. The connector 31 has a first inlet 310 that connects to the water supply mechanism 2 and a first outlet 311 that connects to the outlet pipe. The first inlet 310 and the first outlet 311 are dynamically connected to the cylinder through-hole 700. The first inlet 310 is connected to the water supply mechanism 2 via a water pipe, and the first outlet 311 is connected to the outlet pipe. The cylinder 70 rotates within the connector 31. When water needs to enter, the cylinder 70 rotates to connect the cylinder through hole 700 and the first inlet 310, while the first outlet 311 is not connected to the cylinder through hole 700. When water needs to exit, the cylinder 70 rotates to connect the cylinder through hole 700 and the first outlet 311, while the first inlet 310 is not connected to the cylinder through hole 700. The rotation of the cylinder 70 is achieved by actuating the lever 71. A sealing ring is fitted onto the outer wall of the cylinder 70 between the lower end of the inner wall of the connector 31 and the outer wall of the cylinder 70, thereby sealing the bottom end of the connector 31 and achieving a sealed installation of the cylinder 70 within the connector 31. When selecting a solenoid valve for the water valve 7, such as... Figure 1As shown, the bottom of the first water tank 3 also extends a cylindrical connector 31. The diameter of the connector 31 is smaller than the diameter of the first water tank 3. The connector 31 is also provided with a first inlet 310 and a first outlet 311. At this time, the first inlet 310 and the first outlet 311 can be arranged vertically at intervals. The solenoid valve is installed on the outlet pipe. When the water valve 7 is a mechanical valve, in order to facilitate the control of the water inlet and outlet of the first water tank 3, the first inlet 310 and the first outlet 311 are arranged on different radial directions of the connector 31. The first inlet 310 is located above the first outlet 311. The angle between the axis of the first inlet 310 and the axis of the first outlet 311 is greater than 0 degrees and less than 180 degrees. The cylinder 70 is axially aligned with the first inlet 310 and the first outlet 311. At position 11, there is a cylindrical through hole 700. The two cylindrical through holes 700 are not connected at the same time. This means that the first water inlet 310 and the first water outlet 311 are not on the same straight line in the axial direction, nor are they on the same straight line in the radial direction. The included angle between the axes of the two cylindrical through holes 700 is different from the included angle between the axes of the first water inlet 310 and the first water outlet 311. This way, during the rotation of the cylinder 70, the first water inlet 310 and the first water outlet 311 will not be connected at the same time. That is, when the water valve 7 is connected to the first water inlet 310, the first water outlet 311 is closed, and when the first water outlet 311 is connected, the first water inlet 310 is closed. Setting the first water outlet 311 at the bottom facilitates the flow of water out of the first water tank 3.

[0035] Further improvements, such as Figures 1 to 3 , Figures 6 to 8 , Figure 12 and Figure 13As shown, the mounting frame 1 includes a mounting base 10 and a mounting bracket 11 connected to the mounting base 10. A drive motor 5 is mounted on the top of the mounting base 10 using screws. The output shaft of the drive motor 5 passes through the bottom of the mounting base 10, meaning that the mounting base 10 has a through hole for the output shaft of the drive motor 5 to pass through. The mounting base 10 is equipped with multiple microswitches 12 corresponding to the first water tank 3. The mounting base 10 also has multiple first through holes 13 corresponding to the multiple microswitches 12. Each first through hole 13 has a sliding block 14 that can slidably abut against the corresponding microswitch 12. The mounting base 10 is used to connect a storage container 9 pre-loaded with a quantitative dental mold material. For example, an annular wall extends downwards from the bottom edge of the mounting base 10, forming an inverted barrel-shaped structure. The material storage container 9 is installed inside the barrel-shaped structure; the mounting bracket 11 is installed on the outer wall of the mounting base 10, and a base is provided at the bottom of the mounting bracket 11; the mounting base 10 is also provided with an upper shell 15, which is installed on the mounting base 10 by a snap-fit ​​structure or screws, forming an installation space between the upper shell 15 and the mounting base 10, which is used to install the drive motor 5, etc., thereby protecting them; the water supply mechanism 2 and the first water tank 3 are selected to be installed on the mounting bracket 11 or the mounting base 10 depending on the situation; a notch is provided on the upper shell 15 to facilitate the installation of the water outlet pipe of the first water tank 3; the micro switch 12 is a three-phase micro switch, used to control the electrical conduction of the drive motor 5 and / or the solenoid valve, as well as the water pump; the micro switch 12 is activated by sliding the sliding block 14. The bottom surface of the mounting base 10 has a mounting base slot 100 at the position corresponding to the first through hole 13, which is used to connect a storage container containing dental mold material; for example Figure 1 , Figure 3 , Figure 7 , Figure 8 , Figure 12 and Figure 13As shown, there are two of each of the following: the first water tank 3, the micro switch 12, and the first through hole 13, corresponding to the commonly used dental model materials plaster and alginate. One first water tank 3 is used to provide water for mixing plaster dental model materials, and the other first water tank 3 is used to provide water for mixing alginate dental model materials. The bottom surface of the mounting base 10 has two different mounting base slots 100 at positions corresponding to the two first through holes 13. These different mounting base slots 100 are used to connect the storage containers 9 containing different dental model materials. The storage containers 9 pass through the mounting base slots 100... When connected to the mounting base 10, the sliding block 14 in the corresponding first through hole 13 is pushed to slide. The sliding block 14 moves the lever 71 to rotate, thereby triggering the micro switch 12 to open. An annular wall extends downwards from the bottom edge of the mounting base 10. The mounting base slot 100 is formed by two types of slots respectively provided on the inner wall of the annular wall. These slots are formed by the distance between the side wall protrusions extending from the inner wall of the annular wall and the bottom surface of the mounting base 10. In actual use, according to different dental mold materials, the appropriate amount is weighed and then placed in different storage containers 9, such as... Figure 16As shown, a top cover 90 is provided on the storage container 9. Three top cover blocks 91 extend at equal intervals along the circumference of the top edge of the top cover 90. The top cover blocks 91 can be configured into strip structures or U-shaped structures according to different dental membrane materials. Each type of mounting base slot 100 is provided with three of these. One type has a stop block in front of the mounting base slot 100 that can match and be inserted into the U-shaped opening of the top cover block 91, which is the first slot. The other type is a structure without a stop block in front of the mounting base slot 100, which is the second slot. The two types of slots are arranged in an alternating pattern, meaning there is one and only one second slot between two adjacent first slots. The distance between the front end of the first slot and the rear end of the second slot in front of it is greater than the distance between the rear end of the first slot and the front end of the second slot behind it. The length of the U-shaped top cover block 91 is approximately equal to the distance between the front end of the first slot and the rear end of the second slot in front of it, allowing it to enter between the front end of the first slot and the rear end of the second slot and engage in the first slot. The strip-shaped top cover latch 91 cannot be engaged at this position due to the presence of the stop block. The distance from the stop block to the front end of the first latch and to the rear end of the second latch is less than the length of the strip-shaped top cover latch 91. Similarly, the U-shaped top cover latch 91 cannot be engaged in the second latch from the rear end of the first latch and the front end of the second latch, while the strip-shaped top cover latch 91 can be engaged in the second latch from this position. A first through hole 13 corresponds to any one of the three first latches, and a sliding block 14... The lower end of the sliding block 14 passes through the first through hole 13 and extends into the corresponding first slot. The other first through hole 13 corresponds to any one of the three second slots. The lower end of the other sliding block 14 passes through the other first through hole 13 and extends into the corresponding second slot. When the top cover block 91 is engaged in the mounting base slot 100, it pushes the sliding block 14 to slide. The mounting base 10 is also provided with a mounting base water outlet channel 101 connected to the water outlet pipe. The top cover 90 is provided with a water inlet through hole for water inlet.

[0036] Further improvements, such as Figure 2 As shown, a vibration seat 110 is set on the mounting bracket 1. If the vibration seat 110 is set on the base of the mounting bracket 11, a connecting rod is set on the base of the mounting bracket 11. The end of the connecting rod away from the mounting bracket 11 is set with a vibration base with an internal cavity. A vibration motor is set inside the vibration base. Two base protrusions extend from the left and right sides of the front of the top face of the vibration base. The distance between the two base protrusions is roughly the same as the width of the handle of the dental mold tray. When in use, the handle of the dental mold tray is inserted between the two base protrusions to fix the dental mold tray on the top surface of the vibration base. 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.

[0037] A further improvement to the water outlet channel 101 of the mounting base is to install it on the top surface of the mounting base 10, near the location where the output shaft of the drive motor 5 passes through. Figure 14 and Figure 15 As shown in the diagram; another type is where the water outlet channel 101 of the mounting base is a second water tank 4 installed on the mounting base 10, as shown in the diagram. Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 12 As shown, a second water tank 4 is provided and communicates with multiple first water tanks 3 respectively. A connector 8 is sealed inside the second water tank 4 and can rotate relative to it, with the lower part of the connector 8 outside the second water tank 4. The connector 8 is a cylindrical structure with a sealed top. The second water tank 4 is configured as an inverted barrel shape, with a top through hole coaxial with the connector 8. The drive motor 5 is positioned directly above the second water tank 4, and its output shaft is inserted into the second water tank 4 through the top through hole and connected to the top of the connector 8. The second water tank 4 is connected to the first water tank 3 via a water outlet pipe on its outer wall. A sealing ring is provided between the output shaft of the drive motor 5 and the wall of the top through hole. Figure 4 , Figure 5 , Figure 8 and Figure 13 As shown, a connecting member protrusion extends radially outward around the lower outer wall of the connecting member 8. The connecting member 8 is inserted into the second water tank 4 through the bottom opening. The connecting member protrusion abuts against the end face of the opening of the second water tank 4, sealing the bottom of the second water tank 4. At this time, a sealing element is fitted onto the connecting member 8, located on the top surface of the connecting member protrusion and inserted into the lower part of the second water tank 4, to seal the bottom of the second water tank 4. The connecting member 8 can still rotate within the second water tank 4. The sealing element can be a sealing ring or an oil seal. The connecting member 8 has a connecting member through hole 80 on the side wall located inside the second water tank 4. The water entering the second water tank 4 gradually rises within the tank. When it reaches the through hole 80 of the connector, the water flows into the connector 8 through the through hole 80, then flows out of the connector 8 and into the storage container 9 containing the dental mold material, which is installed at the bottom of the connector 8. The output shaft of the drive motor 5 is sealed to the top of the second water tank 4, and the lower end of the output shaft of the drive motor 5 extends into the second water tank 4 and connects to the top of the connector 8. The stirring head for stirring the dental mold material is connected to the connector 8. As the drive motor 5 drives the connector 8 to rotate, the connector 8 rotates with the stirring head to stir. Figure 7 , Figure 8 and Figure 12As shown, when the water valve 7 is a mechanical valve, the first water tank 3 is installed on the mounting base 10. The lever 71 is provided with a lever through hole 710. The top of the sliding block 14 extends with a sliding block protrusion 140 that inserts into the lever through hole 710. The sliding block 14 has a T-shaped cross section. Its horizontal part is located at the top of the first through hole 13, and its vertical part extends into the first through hole 13 and its lower end protrudes from the lower end of the first through hole 13. The sliding block 14 slides in the first through hole 13, and the sliding block protrusion 140 pushes the lever 71 to rotate. The lever 71 is provided with a cross-shaped structure, the first through hole 13 is provided with an arc-shaped through hole, the lever through hole 710 is provided at the intersection of the cross-shaped structure, and the cylinder 70 is provided at any end of the cross-shaped structure and is perpendicular to the lever 71.

[0038] Further improvements, such as Figure 8 , Figure 10 and Figure 11 As shown, the sealing plug through-hole 60 includes an upper circular through-hole 600, a middle conical through-hole 601, and a lower circular through-hole 602 arranged sequentially. The sealing float 61 is a float installed in the lower through-hole 602 that can float up and block the middle through-hole 601. That is, the diameter of the top end of the middle through-hole 601 is the same as the diameter of the upper through-hole 600, and the diameter of the bottom end of the middle through-hole 601 is the same as the diameter of the lower through-hole 602. Similarly, the diameter of the upper through hole 600 is smaller than the diameter of the lower through hole 602, and the diameter of the sealing float 61 is larger than the diameter of the upper through hole 600 but smaller than the diameter of the lower through hole 602. After water enters the lower through hole 602, the sealing float 61 floats up. During the floating process, the sealing float 61 abuts against the hole wall of the middle through hole 601, thereby sealing the middle through hole 601. The amount of water entering the first water tank 3 is thus determined. The bottom surface of the sealing plug 6 is a conical surface with the bottom end of the lower through hole 602 as the apex. The structure of the conical surface guides the flow of water into the first water tank 3. As the water level rises in the first water tank 3, the water flows into the lower through hole 602, thereby pushing the sealing float 61 to float upward and seal it in the middle through hole 601. The lower end of the hole wall of the lower through hole 602 is provided with multiple hole wall protrusions 603 at intervals along the circumference of the lower through hole 602. The hole wall protrusions 603 prevent the sealing float 7 from falling out of the lower through hole 602. The channel between two adjacent hole wall protrusions 603 constitutes the channel for water to flow into the lower through hole 602.

[0039] Further improvements, such as Figures 1 to 3As shown, the water level in the first water tank 3 is regulated by an electronic water level control switch 30, which is either a first float switch or a liquid level sensor. The water supply mechanism 2 includes a first water supply tank 20 mounted on the mounting bracket 1. A water pump 21 is installed inside the first water supply tank 20 to supply water to the first water tank 3. The first water supply tank 20 includes two water tanks with different volumes. The water valve 7 is a solenoid valve, which is used to control the water output of the first water tank 3. Thus, the first water supply tank 20, the water pump 21, the first water tank 3, the electronic water level control switch 30, the sliding block 14, the micro switch 12, and the solenoid valve correspond to an automatic quantitative water supply system for mixing and stirring dental membrane materials. In use, the first water supply tank 20 is filled with water, and then water is pumped into the first water tank 3 by the water pump 21. The float of the electronic water level control switch 30 rises as water is injected. When the water level in the first water tank 3 reaches the specified requirement, the electronic water level control switch 30 is turned on, and the water pump 21 stops pumping water. When the water pump 21 is injecting water into the first water tank 3, the solenoid valve is closed. After the storage container 9 is installed on the mounting base 10, the installation of the storage container 9 will push the corresponding sliding block 14, which will activate the corresponding micro switch 12. After the micro switch 12 is activated, the drive motor 5 and the solenoid valve corresponding to the micro switch 12 will also be activated accordingly, and the electrical conduction of the water pump 21 will be disconnected. The water in the first water tank 3 will then flow into the storage container 9 after passing through the solenoid valve.

[0040] Further improvements, such as Figures 4 to 8As shown, the first water tank 3 regulates the water volume through a sealing plug 6. The water supply mechanism 2 includes a third water tank 22 connected to the first water tank 3 and mounted on a mounting frame 1, and a second water supply tank 23, which is detachably mounted on the mounting frame 1 and connected to the third water tank 22, and located on top of the third water tank 22. A second float switch 24 is installed inside the third water tank 22. The second water supply tank 23 is detachably mounted on the mounting frame 1 via a snap fastener and is located on top of the third water tank 22. A quick-connect fitting consisting of a male and a female connector is provided between the bottom of the second water supply tank 23 and the top of the third water tank 22 to connect the second water supply tank 23 and the third water tank 22. Water flows into the first water tank 3 through the quick-connect fitting. The second water supply tank 23 is a transparent tank, allowing for real-time monitoring of water supply sufficiency. A handle is also provided on the second water supply tank 23 for easy access. The second float switch 24 is a magnetic float switch. The second water supply tank 23 continuously supplies water to the third water tank 22, which in turn supplies water to the first water tank 3. At this time, the water valve 7 in the first water tank 3 is a mechanical valve. The mechanical valve has two through holes 700 on its cylinder. When the third water tank 22 supplies water to the first water tank 3, the first... The inlet 310 is connected to the corresponding cylindrical through-hole 700, while the first outlet 311 is not connected to the other cylindrical through-hole 700. Water from the third water tank 22 flows into the first water tank 3. When the water level in the first water tank 3 reaches the specified usage, the sealing float 61 blocks the sealing plug through-hole 60, and water from the third water tank 22 no longer flows into the first water tank 3. At this time, the float of the second float switch 24 in the third water tank 22 also rises to the specified height, and the second float switch 24 opens. When the water level in the first water tank 3 has not reached the specified usage, water from the third water tank 22 continuously flows into the first water tank 3, and the second float switch 24 opens. The float ball of valve 24 will not rise to the specified height, and the drive motor cannot be started. After the storage container 9 is installed on the mounting base 10, the installation of the storage container 9 will push the corresponding sliding block 14. The sliding block 14 will activate the corresponding micro switch 12 and push the lever 71 to rotate so that the first water outlet 311 and the other cylinder through hole 700 are connected. At this time, the second float switch 24 and the micro switch 12 are both in the open state, and the drive motor 5 is electrically turned on. The water in the first water tank 3 flows into the storage container 9 after passing through the mechanical valve to achieve automatic quantitative water supply, which is more convenient to use and achieves consistency after mixing and stirring of dental mold materials.

[0041] Further improvements, such as Figure 13As shown, multiple connector blocks 81 for connecting the stirring head are evenly spaced along the circumference of the connector 8 at the same height on the outer wall of the lower part of the connector 8. When the stirring head is placed in the storage container 9, the top surface of the top cover of the storage container 9 has a countersunk circular storage container through hole at the center. The top of the stirring head is a rotating ring set in the storage container through hole. The inner wall of the stirring head is provided with a slot that matches and engages with the connector blocks 81. The stirring head is connected to the connector 8 by the cooperation of the connector blocks 81 and the slot. At this time, when the water outlet channel 101 of the mounting base is located near the output shaft of the drive motor 5, the top cover 90 of the storage container 9 is set with a structure that gradually concaves from the edge to the center. The number of slots on the inner wall of the stirring head is more than the number of connector blocks 81. The extra slots can serve as water inlets for the storage container 9. Before the drive motor 5 is started, water flows from the water outlet channel of the mounting base to the top cover 90, and then flows into the storage container 9 from the extra slots.

Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
