Description

Technical Field

[0001] The present invention relates to the field of oral impression devices, and in particular, to an automated stirrer for mixing dental impression materials. Background Art

[0002] When making dental impressions, it is usually necessary to stir and mix dental impression materials and water. In the prior art, manual stirring and mixing of dental impression materials and water are used. Commonly used dental impression materials are gypsum or alginate, and their mixing ratios with water are different. When manually stirring, there will be problems with the proportion of dental impression materials and water added.

[0032] The present invention will be further described below in conjunction with embodiments. A clear and complete description should be understood. These embodiments are used to illustrate the present invention and are not limited to restricting the scope of the present invention. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers. The implementation conditions not specified are usually the conditions in conventional experiments. In addition, the directional terms mentioned in the present invention, for example, "up", "down", "front", "rear", "left", "right", "inside", "outside", etc., are only references to the directions in the attached drawings. The directional terms used are for better and clearer illustration and understanding of the present invention, rather than indicating or implying the directions that the present invention must have. Therefore, they cannot be construed as limitations on the present invention.

[0033] Embodiments of the present invention are as follows Figures 1 to 16As shown in [figure reference], an automated stirrer for mixing dental impression materials includes a mounting frame 1, on which a water supply mechanism 2, multiple first water tanks 3 each capable of regulating the water storage volume and connected to a water outlet pipe and respectively communicating with the water supply mechanism 2, and a driving motor 5 are installed. The water supply mechanism 2 and the first water tanks 3 are communicated through the inlet pipes (not shown in the figure) of the first water tanks 3. The water outlet of the first water tanks 3 directly discharges water through the water outlet pipes (not shown in the figure) or is connected to other components for water discharge. Both the inlet pipes and the water outlet pipes are connected using existing hoses. At this time, the water outlet pipes of the first water tanks 3 can directly transport water to the storage container 9 containing dental impression materials, or other intermediate media can be connected between the water outlet pipes and the storage container 9 to finally transport water to the storage container 9; the first water tanks 3 can be adjusted according to the usage requirements to be water tanks capable of storing different water volumes, thereby meeting the water required for mixing different types of dental impression materials. For a certain type of dental impression material, its powder-to-water ratio is determined. At this time, only the volume of water that the first water tanks 3 can store needs to be adjusted to match the water volume required for mixing the dental impression materials. The amount of dental impression powder weighed each time is determined, and the amount of water added to it is also determined, thus achieving quantitative water use and ensuring the consistency of dental impression material mixing. Multiple first water tanks 3 correspond to the mixing of multiple types of dental impression materials. When mixing different dental impression materials, there is no need to replace the equipment, which is convenient for use. For example, if two first water tanks 3 are set, they correspond to conventional gypsum and alginate dental impression materials; the water supply mechanism 2 is used to supply water to the first water tanks 3. The output shaft of the driving motor 5 can be directly connected to the stirring head for stirring to drive the stirring head, or a connecting piece 8 for connecting the stirring head can be connected to the output shaft of the driving motor 5, and the rotation of the connecting piece 8 is driven to drive the stirring head connected to the connecting piece 8 to rotate for stirring;The first water tank 3 regulates the water storage capacity that can be stored in the first water tank 3 through an electronic water level control switch 30 provided therein or a sealing plug 6 hermetically arranged in the first water tank 3. That is to say, the electronic water level control switch 30 or the sealing plug 6 is used to control the water storage capacity in the first water tank 3. According to the usage requirements, the electronic water level control switch 30 or the sealing plug 6 is arranged at different positions in the first water tank 3. When the water inlet in the first water tank 3 reaches the set water storage capacity, the electronic water level control switch 30 or the sealing plug 6 is used to stop the water inlet into the first water tank 3. The sealing plug 6 is hermetically installed in the first water tank 3. According to different water consumption requirements, the sealing plug 6 is installed at the corresponding height in the first water tank 3. The sealing plug 6 can also be slidable up and down in the first water tank 3 and hermetically installed. By sliding the sealing plug 6 up and down in the first water tank 3, the position of the sealing plug 6 in the first water tank 3 can be conveniently adjusted. For example, the first water tank 3 is set as a cylindrical structure, and a pull rod is threadedly connected to the top of the sealing plug 6 to pull the sealing plug 6 to move up and down in the first water tank 3. After determining the height of the sealing plug 6 in the first water tank 3, the pull rod can be removed, and the adjustment of the water storage space size of the first water tank 3 for storing water, that is, the adjustment of the water storage capacity of the first water tank 3, is completed; a sealing ring is sleeved on the outer wall of the sealing plug 6 to achieve sealing; for the structure of the sealing plug 6, such as; Figure 8 , Figure 10 and Figure 11 As shown in, a sealing plug through hole 60 with a conical structure is arranged at the center of the sealing plug 6. When water enters the first water tank 3, the air therein can be discharged from the sealing plug through hole 60. A spherical blocking floating ball 61 that can float up and block the sealing plug through hole 60 is installed in the sealing plug through hole 60. The conical structure of the sealing plug through hole 60 means that the diameter size of its upper part is smaller than that of its lower part, and the diameter size of the blocking floating ball 61 is between the diameter size of the upper part and the diameter size of the lower part of the sealing plug through hole 60. When water enters the first water tank 3, the blocking floating ball 61 will float upward towards the upper end of the sealing plug through hole 60. After floating to a certain height, the blocking floating ball 61 will be tangent to the hole wall of the sealing plug through hole 60 in the circumferential direction to block the sealing plug through hole 60; A water valve 7 is also arranged on the first water tank 3 to control the water inlet and outlet in the first water tank 3. A water valve 7 is arranged on each first water tank 3.

[0034] For further improvement, the water valve 7 is an electromagnetic valve or a mechanical valve arranged on the first water tank 3. As shown in Figure 1 is an electromagnetic valve, Figure 7 , Figure 8 and Figure 12What is shown in the figure is a mechanical valve, that is, the water valve 7 adopts two different structures, one is an electromagnetic valve controlled by electricity, and the electromagnetic valve can adopt any existing electromagnetic valve, and the other is a valve controlled by a mechanical structure; the mechanical valve includes a cylinder 70 with a closed bottom end, a paddle 71 arranged on the outer wall of the lower end of the cylinder 70, and a cylinder through hole 700 is arranged on the cylinder 70. A cylindrical joint part 31 extends from the bottom of the first water tank 3, and the diameter of the joint part 31 is smaller than the diameter of the first water tank 3. The cylinder 70 is sealed and rotatably installed in the joint part 31. The joint part 31 is provided with a first water inlet 310 that can be connected to the water supply mechanism 2 and a first water outlet 311 that can be connected to the water outlet pipe. The first water inlet 310 and the first water outlet 311 are dynamically connected to the cylinder through hole 700. , the first water inlet 310 is connected to the water supply mechanism 2 through a water pipe, the first water outlet 311 is connected to the water outlet pipe, and the cylinder 70 rotates in the joint part 31. When water needs to be inlet, the cylinder 70 is rotated so that the cylinder through hole 700 and the first water inlet 310 are connected. At this time, the first water outlet 311 is disconnected from the cylinder through hole 700. When water needs to be discharged, the cylinder 70 is rotated so that the cylinder through hole 700 and the first water outlet 311 are connected, while the first water inlet 310 and the cylinder through hole 700 are disconnected; the rotation of the cylinder 70 is achieved by turning the paddle 71; a sealing ring is provided between the lower end of the inner wall of the joint part 31 and the outer wall of the cylinder 70 and is sleeved on the outer wall of the cylinder 70, so that the bottom end of the joint part 31 is sealed to achieve the sealed installation of the cylinder 70 in the joint part 31. When the water valve 7 selects a solenoid valve, such as Figure 1As shown in, a cylindrical joint portion 31 is also extended from the bottom of the first water tank 3, and the diameter of the joint portion 31 is smaller than the diameter of the first water tank 3. A first water inlet 310 and a first water outlet 311 are also arranged on the joint portion 31. At this time, the first water inlet 310 and the first water outlet 311 can be arranged at intervals up and down in the vertical direction, and the solenoid valve is arranged on the water outlet pipe; when the water valve 7 selects a mechanical valve, in order to facilitate the regulation of the water inlet and outlet of the first water tank 3, the first water inlet 310 and the first water outlet 311 are arranged on different radial directions of the joint portion 31, and the first water inlet 310 is arranged above the first water outlet 311. The angle between the axis of the first water inlet 310 and the axis of the first water outlet 311 is greater than 0 degree and less than 180 degrees, and the cylinder 70 corresponds to the first water inlet 310 and the first water outlet 3 in the axial direction. A cylinder through hole 700 is respectively provided at the position of 11, and the two cylinder through holes 700 are not connected at the same time, which means that the first water inlet 310 and the first water outlet 311 are not on the same straight line in the axial direction, and are not on the same radial straight line in the radial direction. The angle between the axes of the two cylinder through holes 700 is different from the angle between the axes of the first water inlet 310 and the first water outlet 311, so that the first water inlet 310 and the first water outlet 311 will not be connected at the same time during the rotation of the cylinder 70, 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; arranging the first water outlet 311 at the bottom facilitates the outflow of water in the first water tank 3.

[0035] Further improvements such as Figures 1 to 3 , Figures 6 to 8 , Figure 12 and Figure 13As shown in the figure, the mounting bracket 1 includes a mounting base 10 and a mounting support 11 connected to the mounting base 10; the driving motor 5 is installed on the top of the mounting base 10 by screws, and the output shaft of the driving motor 5 passes through the bottom of the mounting base 10, which means that there is a through hole on the mounting base 10 for the output shaft of the driving motor 5 to pass through; a plurality of micro switches 12 corresponding to the first water tank 3 are installed on the mounting base 10, and a plurality of first through holes 13 corresponding to the plurality of micro switches 12 are provided on the mounting base 10. A sliding block 14 that can be in movable abutment with the corresponding micro switch 12 is slidably provided in each first through hole 13. The mounting base 10 is used to connect the storage container 9 pre-filled with a quantitative dental impression material. For example, a circular wall extending downward is provided at a position near the edge of the bottom of the mounting base 10 so that the mounting base 10 forms an inverted bucket-shaped structure, and the storage container 9 containing the dental impression material can be installed inside the bucket of the bucket-shaped structure; the mounting support 11 is installed on the outer side wall of the mounting base 10, and a base is provided at the bottom end of the mounting support 11; an upper shell 15 is also provided on the mounting base 10, and the upper shell 15 is installed on the mounting base 10 by a snap structure or screws. An installation space is formed between the upper shell 15 and the mounting base 10, and the driving motor 5 etc. are installed in this installation space to protect them. The water supply mechanism 2 and the first water tank 3 are installed on the mounting support 11 or the mounting base 10 according to different situations. A notch is provided on the upper shell 15 to facilitate the setting of the water outlet pipe of the first water tank 3; the micro switch 12 is a three-phase micro switch, which is used to control the electrical conduction of the driving motor 5 and / or the solenoid valve and the water pump. The micro switch 12 is activated by the sliding of the sliding block 14, thereby turning on the micro switch. A mounting base slot 100 is provided at the bottom surface of the mounting base 10 corresponding to the first through hole 13, and the mounting base slot 100 is used to connect the storage container containing the dental impression material; such as Figure 1 , Figure 3 , Figure 7 , Figure 8 , Figure 12 and Figure 13As shown in the figure, there are two first water tanks 3, micro switches 12, and first through holes 13, corresponding to the commonly used dental impression materials, plaster and alginate. One first water tank 3 is used to supply water for mixing plaster dental impression materials, and the other first water tank 3 is used to supply water for mixing alginate dental impression materials. At the positions corresponding to the two first through holes 13 on the bottom surface of the mounting base 10, two different mounting base card slots 100 are provided, and different mounting base card slots 100 are used to connect the storage containers 9 filled with different dental impression materials. When the storage container 9 is connected to the mounting base 10 through the mounting base card slot 100, the sliding block 14 in the corresponding first through hole 13 is pushed to slide, and the sliding of the sliding block 14 causes the dial 71 to rotate and then touches the micro switch 12 to turn on. At the bottom edge of the mounting base 10, a circular wall extends downward. The mounting base card slots 100 are two kinds of card slots respectively provided on the inner wall of the circular wall, and they are formed by the distance between the side wall protrusions extending from the inner wall of the circular wall and the bottom surface of the mounting base 10. In actual use, according to different dental impression materials, the corresponding dosages are weighed and then placed in different storage containers 9, such as Figure 16As shown in the figure, a top cover 90 is provided on the storage container 9. Three top cover blocks 91 extend equidistantly along the circumferential direction of the top cover 90 at the top edge of the top cover 90. The top cover blocks 91 can be set into a strip structure or a U-shaped structure according to different dental film materials. Each mounting seat slot 100 is provided with three. One is that there is a stop block in front of the mounting seat slot 100 that can be inserted into the U-shaped opening of the U-shaped top cover block 91 in a matching manner, which is the first slot. The other is a structure without a stop block in front of the mounting seat slot 100, which is the second slot. The two slots are arranged in a cross manner, that is, there is exactly 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 equivalent to the distance between the front end of the first slot and the rear end of the second slot in front of it, and it can enter from between the front end of the first slot and the rear end of the second slot and be clamped in the first slot. Due to the existence of the stop block, the strip-shaped top cover block 91 cannot be inserted from this position, and the distances from the stop block to the front end of the first slot and to the rear end of the second slot are both less than the length of the strip-shaped top cover block 91. Similarly, the U-shaped top cover block 91 cannot be inserted into the second slot from the position between the rear end of the first slot and the front end of the second slot, while the strip-shaped top cover block 91 can be inserted into the second slot from this position; a first through hole 13 corresponds to any one of the three first slots, and the lower end of a sliding block 14 passes through the first through hole 13 and extends into the corresponding first slot. Another first through hole 13 corresponds to any one of the three second slots, and the lower end of another 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 inserted into the mounting seat slot 100, it pushes the sliding of the sliding block 14; an installation seat water outlet channel 101 communicating with the water outlet pipe is also provided on the mounting seat 10, and an inlet through hole for water inlet is provided on the top cover 90.

[0036] For further improvement, as Figure 2 shown in the figure, a vibration seat 110 is provided on the mounting frame 1. For example, the vibration seat 110 is provided on the base of the mounting bracket 11. For example, a connecting rod is provided on the base of the mounting bracket 11, and the end of the connecting rod away from the mounting bracket 11 is provided with a vibration base with a cavity inside. A vibration motor is provided inside the vibration base. Two base protrusions extend from the left and right sides of the front side of the top surface of the vibration base. The distance between the two base protrusions is equivalent to the width of the handle of the dental mold tray. During use, the handle of the dental mold tray is clamped between the two base protrusions to fix the dental mold tray on the top surface of the vibration base, and then the vibration motor is started to vibrate the dental mold tray. The dental film material coated on the dental mold tray will remove air bubbles during vibration and be evenly laid on the dental mold tray.

[0037] For further improvement, regarding the water outlet channel 101 of the mounting base, one way is to set it at a position adjacent to the position where the output shaft of the driving motor 5 penetrates through the top surface of the mounting base 10, as shown in Figure 14 and Figure 15 ; the other way is that the water outlet channel 101 of the mounting base is arranged in the second water tank 4 on the mounting base 10, as shown in Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Figure 12 . The second water tank 4 is provided with one and is respectively communicated with a plurality of first water tanks 3. The connecting piece 8 is hermetically arranged in the second water tank 4 and can rotate relative to the second water tank 4, and the lower part of the connecting piece 4 is outside the second water tank 4. At this time, the connecting piece 8 is a cylindrical structure with a sealed top. The second water tank 4 is arranged in an inverted bucket shape, and a top through hole coaxial with the connecting piece 8 is arranged at its top. At this time, the driving motor 5 is arranged directly above the second water tank 4, and the output shaft of the driving motor 5 is inserted into the second water tank 4 from the top through hole and connected to the top of the connecting piece 8. The second water tank 4 is communicated with the first water tank 3 through the water outlet pipe of the first water tank 3 on the outer side wall. A sealing ring is arranged between the output shaft of the driving motor 5 and the hole wall of the top through hole; as shown in Figure 4 , Figure 5 , Figure 8 and Figure 13 . On the outer wall of the lower part of the connecting piece 8, a connecting piece protrusion extends radially outward around the connecting piece 8 for one week. The connecting piece 8 is inserted into the second water tank 4 from the bottom opening of the second water tank 4, and the connecting piece protrusion abuts against the end surface of the opening end of the second water tank 4 to seal the bottom of the second water tank 4. At this time, a sealing member sleeved on the connecting piece 8 and located on the top surface of the connecting piece protrusion and inserted into the lower part of the second water tank 4 seals the bottom of the second water tank 4, and the connecting piece 8 can still rotate in the second water tank 4; the sealing member can be a sealing ring or an oil seal; the connecting piece 8 is provided with a connecting piece through hole 80 on the side wall located in the second water tank 4. In this way, the water entering the second water tank 4 gradually rises in the second water tank 4. When it rises to the connecting piece through hole 80, the water flows into the inside of the connecting piece 8 from the connecting piece through hole 80, and then flows out from the inside of the connecting piece 8 and flows into the material storage container 9 filled with dental impression material installed at the bottom of the connecting piece 8; the output shaft of the driving motor 5 is hermetically connected to the top of the second water tank 4, and the lower end of the output shaft of the driving motor 5 extends into the second water tank 4 and is connected to the top of the connecting piece 8. The stirring head for stirring the dental impression material is connected to the connecting piece 8. As the driving motor 5 drives the connecting piece 8 to rotate, the connecting piece 8 drives the stirring head to rotate for stirring. As shown in Figure 7 , Figure 8 and Figure 12As shown in the figure, when the water valve 7 is a mechanical valve, the first water tank 3 is installed on the mounting seat 10. A through hole 710 is provided on the paddle 71, and a sliding block protrusion 140 extending from the top of the sliding block 14 is inserted into the through hole 710 of the paddle. The cross-section of the sliding block 14 is in a T-shaped structure, the horizontal part of which is at the top end of the first through hole 13, the vertical part extends into the first through hole 13 and the lower end passes out 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 paddle 71 to rotate. The paddle 71 is arranged in a cross-shaped structure, the first through hole 13 is arranged as an arc-shaped through hole, the through hole 710 of the paddle is arranged at the intersection of the cross-shaped structure, and the cylinder 70 is arranged at any end of the cross-shaped structure and is perpendicular to the paddle 71.

[0038] Further improvements, such as Figure 8 、 Figure 10 and Figure 11 As shown in the figure, the sealing plug through hole 60 includes an upper through hole 600 which is circular in the upper part, a middle through hole 601 which is conical in the middle part, and a lower through hole 602 which is circular in the lower part. The plugging floating ball 61 is a floating ball installed in the lower through hole 602 and can float up to block the middle through hole 601. That is to say, the diameter of the top end of the middle through hole 601 is the same as that of the upper through hole 600, the diameter of the bottom end of the middle through hole 601 is the same as that of the lower through hole 602, the diameter of the upper through hole 600 is smaller than that of the lower through hole 602, the diameter of the plugging floating ball 61 is larger than that of the upper through hole 600 and smaller than that of the lower through hole 602. After water enters the lower through hole 602, the plugging floating ball 61 floats up, and during the floating process, the plugging floating ball 61 abuts against the hole wall of the middle through hole 601 to block the middle through hole 601, and 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 vertex. The structure of the conical surface guides the flow of water entering the first water tank 3. As the water level in the first water tank 3 rises, the water flows into the lower through hole 602, thereby pushing the plugging floating ball 61 to float upward and block it in the middle through hole 601. A plurality of hole wall protrusions 603 are arranged at intervals along the circumferential direction of the lower end of the hole wall of the lower through hole 602. The arrangement of the hole wall protrusions 603 prevents the plugging floating ball 7 from falling out of the lower through hole 602, and the channels between adjacent two hole wall protrusions 603 form the channels for water to flow into the lower through hole 602.

[0039] Further improvements, such as Figures 1 to 3As shown in the figure, the water storage volume of the first water tank 3 is regulated by an electronic water level control switch 30, which is a first float switch or a liquid level sensor. The water supply mechanism 2 includes a first water supply tank 20 installed on the mounting bracket 1. A water pump 21 for supplying water to the first water tank 3 is provided inside the first water supply tank 20. The first water supply tank 20 includes two water tanks with different volumes. The water valve 7 is selected as an electromagnetic valve, and the water valve 7 is used to control the water outlet of the first water tank 3. In this way, a first water supply tank 20, a water pump 21, a first water tank 3, an electronic water level control switch 30, a sliding block 14, a microswitch 12, and an electromagnetic valve correspond to an automatic quantitative water supply system for mixing and stirring dental film materials. When in use, the first water supply tank 20 is filled with water, and then the water pump 21 pumps water to fill the first water tank 3. The float of the electronic water level control switch 30 floats as the water is injected. When the water volume 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 injects water into the first water tank 3, the electromagnetic valve is in a closed state. After the storage container 9 is installed on the mounting seat 10, the installation of the storage container 9 will push the corresponding sliding block 14, and the sliding block 14 will activate the corresponding microswitch 12. After the microswitch 12 is activated, the drive motor 5 and the electromagnetic valve corresponding to the microswitch 12 are also activated accordingly, and at the same time, the electrical conduction of the water pump 21 is disconnected. The water in the first water tank 3 flows into the storage container 9 after passing through the electromagnetic valve.

[0040] Further improvements, such as Figures 4 to 8As shown in the figure, the water storage capacity of the first water tank 3 is regulated by a sealing plug 6. The water supply mechanism 2 includes a third water tank 22 installed on the mounting frame 1 and connected to the first water tank 3, and a second water supply tank 23 detachably installed on the mounting frame 1 at the top of the third water tank 22 and connected to the third water tank 22. A second float switch 24 is arranged in the third water tank 22. The second water supply tank 23 is detachably installed on the mounting frame 1 by a buckle and is located at the top of the third water tank 22. A quick-connect joint composed of a male head and a female head is arranged 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. Then, water flows into the first water tank 3 through the quick-connect joint. The second water supply tank 23 is set as a transparent box body, and the transparent structure can be used to know in real time whether the water supply is sufficient. At the same time, a handle can be arranged on the second water supply tank 23 to facilitate the taking and placing of the second water supply tank 23. The second float switch 24 selects a magnetic float switch. The second water supply tank 23 continuously supplies water to the third water tank 22, and the third water tank 22 supplies water to the first water tank 3. At this time, the water valve 7 in the first water tank 3 selects a mechanical valve. Two cylinder through holes 700 are arranged on the mechanical valve. When the third water tank 22 supplies water to the first water tank 3, the first water inlet 310 on the first water tank 3 is communicated with the corresponding cylinder through hole 700, and the first water outlet 311 is not communicated with the other cylinder through hole 700. The water in the third water tank 22 flows into the first water tank 3. When the water in the first water tank 3 reaches the specified amount, the plugging float 61 plugs the sealing plug through hole 60, and the water in the third water tank 22 no longer supplies water to the first water tank 3. At this time, the float of the second float switch 24 in the third water tank 22 also floats to the specified height, and the second float switch 24 is turned on. When the water in the first water tank 3 does not reach the specified amount, the water in the third water tank 22 continuously supplies water to the first water tank 3, and the float of the second float switch 24 will not float to the specified height, so the drive motor cannot be started. After the storage container 9 is installed on the mounting seat 10, when installing the storage container 9, the corresponding sliding block 14 will be pushed. The sliding block 14 activates the corresponding micro switch 12 and pushes the dial 71 to rotate so that the first water outlet 311 is communicated with the other cylinder through hole 700. At this time, both the second float switch 24 and the micro switch 12 are in the on state, and the drive motor 5 is electrically conducted. The water in the first water tank 3 flows into the storage container 9 through the mechanical valve to achieve automatic quantitative water supply, which is more convenient to use and realizes the consistency after the dental model material is mixed and stirred.

[0041] Further improvement, such as Figure 13As shown in the figure, on the outer wall of the lower part of the connecting piece 8, a plurality of connecting piece clamping blocks 81 for connecting the stirring head are arranged at equal intervals along the circumferential direction of the connecting piece 8 at the same height. When the stirring head is arranged in the storage container 9, a countersunk circular storage container through hole is provided at the center of the top surface of the top cover of the storage container 9. The top of the stirring head is a ring that rotates in the storage container through hole. A clamping groove that matches and engages with the connecting piece clamping block 81 is arranged on the inner wall of the stirring head. Through the cooperation of the connecting piece clamping block 81 and the clamping groove, the stirring head is connected to the connecting piece 8. At this time, when the water outlet channel 101 of the mounting seat is arranged in the vicinity of the output shaft of the driving motor 5, the top cover 90 of the storage container 9 is set to have a structure that gradually concaves from the edge to the center. The number of clamping grooves on the inner wall of the stirring head is set to be more than the number of connecting piece clamping blocks 81, and the extra clamping grooves can serve as the water inlet holes of the storage container 9. Before the driving motor 5 is started, water flows from the water outlet channel of the mounting seat to the top cover 90, and then flows into the storage container 9 from the extra clamping grooves.
