[background technology]
Clinical observation and two kinds of methods of laboratory simulation are generally adopted in the abrasion resistance evaluation of dental prosthetic material.Because the clinical follow method cycle is long, expense is high, be difficult to standardization; Chemical constitution is to the influence of material in temperature variation in the oral cavity and the food during to the mechanical wear of material production, feed when simulating teeth chewing better, and the scholar has designed multi-form artificial oral cavity analog machine up to now.Advanced relatively at present is the artificial oral cavity of Programmable Multifunction machine, mainly by 8 sample holder, and the stepper motor of 2 computer controls, 2 electronic water baths and 1 control box are formed.2 stepper motors drive the vertical movement of oral cavity machine simulation central occlusion and the tangential movement of nearly middle interlock far away respectively; 2 electronic water baths provide the hot and cold water circulation; Test macro is handled appearance, optical sensor manipulation appearance and computerized control system 4 parts by three-dimensional laser scanner, motor and is formed.After this device fundamental purpose is to simulate oral cavity interlock and temperature variation; Observe the various changes of properties of material; Especially surperficial wearing and tearing etc., but can not make an experiment with the recovery and the analysis of liquid, Substance Properties that material is discharged in experimentation and quality can not be clear and definite.
Shown in Figure 3 is oral cavity occluder technology exploded view commonly used in the prior art, is made up of control segment count and mechanical snap device, wherein; 10a is the electromagnet trigger point, and 17a is a steady arm, and 11a is an impact head; 13a is a pedestal, and 19a is the test specimen cavity, and 16a is an adjustable bolt.Do the time spent, electromagnet trigger point 10a acts on impact head 11a, and impact head 11a impact test piece, test specimen directly place test specimen cavity 19a, is in an open relatively environment, and electrolytic liquid can't reclaim like this.
Oral environment is relatively complicated, only simulates mechanical understressing to simulate oral environment fully.Simultaneously; The human teeth is occluding with certain interval, and every day, average interlock number of times was constant relatively, and single inconstant mechanical stress factors can not the various variations of reaction material in oral environment; Open electrolyte solution contact level is wide excessively; Experimental precision is poor, can't reclaim analysis, brings difficulty for the evaluation of material and the understanding of performance.
[summary of the invention]
The object of the present invention is to provide a kind of analyze material composition in the liquid separate out and then identify the artificial oral cavity circulation occluder with the recyclable liquid of concentration analysis.
For realizing above purpose, the present invention discloses following technical scheme: a kind of artificial oral cavity circulation occluder of recyclable liquid comprises control segment count and mechanical snap device; Said control segment count produces pulsed power supplies, is made up of Switching Power Supply, auxiliary reclay, the time relay, transistored counter, counter-controller and control transformer, and said mechanical snap device is by the position of having an effect; Test specimen cavity and pedestal are formed, and the said position of having an effect comprises electromagnetic inductor, electromagnetic core, electromagnet trigger point, impact head and steady arm, and said electromagnet trigger point is arranged on the electromagnetic core bottom; Steady arm one end is fixedly connected with the electromagnetic core bottom; The other end and pedestal top flexibly connect, and adjustable bolt and test specimen cavity are set in the said pedestal, and said test specimen cavity is above adjustable bolt; Impact head is positioned at test specimen cavity central authorities just; In the said test specimen cavity container is set, impact head places in the container just, and the height of impact head is more than or equal to the height of container; The impact head upper end is provided with a gland bonnet, and the electromagnet trigger point contacts with gland bonnet just.
Pressure when impacting in order to reduce container is provided with cushion pad above adjustable bolt.
For fixed container better, in the said test specimen cavity retainer plate is set.
The invention has the advantages that: the mechanical snap device combines with the control segment count, and control segment count Control current has or not or size etc., produces pulsed power supplies and excites the electromagnetic type engaging device.The control segment count is that common common electronic engineering is used; Mechanical snap partly installs the impact head of band tooth additional; And install the container of laying material and electrolytic liquid additional; And, utilize rubber buffer to prevent that container is broken to the splashing of container seals, maintenance prevents container inclination and content, simulate the human body oral environment as far as possible.
This device can not only well be simulated human teeth's bite stress, regulates the size of power, can also write down the interlock number of times, and recyclable experiment is simultaneously identified and concentration analysis with electrolytic liquid and then to the material composition of separating out.This device has with electrolytic liquid and then to the material composition of separating out to be identified and concentration analysis.It is simple, easy to operate that this device has an apparatus structure, and recyclable experiment advantage such as analyzes with electrolytic liquid, can be widely used in the experimental evaluation of various dental prosthetic compaction materials.
