Description

Technical Field

[0001] The invention relates to the technical field of teaching experiment equipment, in particular to a chemical experiment training device. Background Art

[0002] Chemical experiments are an important part of the chemistry discipline. Through experimental training, students can deeply understand chemical theoretical knowledge, improve experimental skills and hands-on ability, and cultivate observation, thinking and expression abilities. Chemical experiments are also widely used in industrial production and can effectively promote the development of chemistry and other disciplines.

[0003] For the safety of the experiment and to minimize the waste of materials, the training instructor will usually demonstrate a chemical experiment before students conduct the experiment so that students can understand how to perform the operation correctly and in a standardized manner. When teachers conduct chemical experiment training, they often need the assistance of chemical experiment training equipment, that is, the laboratory table and various instruments on the laboratory table.

[0004] The existing chemical experiment training devices often have the following problems during use. Specifically, during the experimental training process, students usually form one or more circles around the training instructor and the experimental table to observe the operations in the experimental process. However, in the actual training process, due to the limitation of observation distance, mutual occlusion of surrounding students and other factors, the number of students trained at one time is obviously limited, which is not convenient for batch training; and the positions of the students watching are different, resulting in different observation angles. In addition, the occlusion of the training instructor's body parts, changes in light brightness and other factors make it impossible for students to clearly, intuitively and comprehensively observe the operations in the chemical experiment.

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0061] See attached Figure 1 , Attachment Figure 3 and attached Figure 6The embodiment of the present invention discloses a chemical experiment training device, including a laboratory table 1, a mobile component 2, and a camera component 3. A first chamber 101 is provided inside the laboratory table 1, and a first visual window 4 corresponding to the first chamber 101 is provided on the top of the laboratory table 1. A control device 5 is provided inside the first chamber 101. The control device 5 includes a display screen 51 corresponding to the first visual window 4. The control devices 5 in different laboratory tables 1 are electrically connected so that one control device 5 can control multiple display screens 51 at the same time; the mobile component 2 is arranged inside the first chamber 101 and located above the control device 5. The mobile component 2 is driven and connected with a lighting component 6. The mobile component 2 can drive the lighting component 6 to move between the display screen 51 and the first visual window 4. The top of the lighting component 6 can emit light to fill in the scene above the first visual window 4; the camera component 3 is installed on the laboratory table 1 and is arranged corresponding to the first visual window 4. The camera component 3 is electrically connected to the control device 5 to shoot the operation of the training instructor during the experiment and present it on the display screen 51.

[0062] In actual use, students are asked to stand in front of different experimental tables 1 respectively, and then operate the chemical experiment training device in front of the training instructor, turn on the camera component 3, operate the control device 5, and present the scene captured by the camera component 3 on multiple display screens 51, operate the moving component 2, and move the lighting component 6 between the display screen 51 and the first visual window 4 to illuminate the scene above the first visual window 4, and then place various items needed on the experimental table 1, and perform experimental operations just above the first visual window 4. Students can observe on the corresponding display screen 51 to complete the training; because the scene on the experimental table 1 in one chemical experiment training device can be presented on the display screen 51 in other chemical experiment training devices, students do not need to watch the operation of the training instructor, and can observe the scene on the screen 51 through the face-to-face interaction. The display screen 51 in front can be used for viewing, and there is no limit on the distance from the training instructor, and the surrounding classmates will no longer block each other, so more students can be trained at one time; because the scenes presented on each display screen 51 are consistent, there will be no situation where students with different standing positions and standing angles view different scenes and ask different questions, as long as one student can see the complete operation process, other students can also see the same, the teaching knowledge will not be differentiated, and it is more conducive to unified training and teaching, and the operation process is carried out above the first visible window 4 illuminated by the lighting component 6, so the influence of shadows is small, so that students can observe more clearly, intuitively and comprehensively; in general, by using the chemical experiment training device, more students can be trained at one time, and the training effect is better.

[0063] See attached Figure 4 , Attachment Figure 6 and attached Fig. 9It should be noted that the above-mentioned control device 5 and display screen 51 are prior art, and the control device 5 also includes components such as a host 52 and a keyboard 53; one control device 5 can control other control devices 5, which also belongs to the prior art, such as the operation of a teacher in a computer room during teaching or the unified operation of multiple computers by the invigilator during a computer-based examination. One computer can control multiple computers, which is widely used in real life. Its working principle also belongs to the prior art, and it will not be described in detail here.

[0064] Furthermore, a transparent silicone pad can be laid on the top of the experimental table 1, which can not only play a certain buffering role to prevent the experimental instruments from making hard contact with the experimental table 1 and causing damage, such as the breakage of a glass measuring cup, but also prevent the corrosive substances used or generated during the experiment from splashing directly onto the experimental table 1 and causing damage to the experimental table 1. After the silicone pad is damaged, only the silicone pad needs to be replaced, which saves time and effort, and can also save costs because there is no need to replace or repair the larger experimental table 1. In addition, since the silicone pad is transparent, it will not affect the normal use of the lighting component 6.

[0065] See attached Figure 5 -Attached Figure 7 There are many structures that can play the role of moving parts. In order to facilitate understanding of the structure of the chemical experiment training device, one of the design methods of the moving component 2 is introduced in this embodiment. Specifically, the lighting component 6 includes two light-emitting panels 61, and the moving component 2 includes a motor 21, a bidirectional screw 22, a guide rod 23, and two moving blocks 24. The motor 21 is arranged on the experimental table 1; the bidirectional screw 22 is rotatably connected to the inside of the first chamber 101, and one end of the bidirectional screw 22 is driven to connect the motor 21; the guide rod 23 is arranged inside the first chamber 101, and the extension direction of the guide rod 23 and the extension direction of the bidirectional screw 22 are parallel to each other; a threaded hole 241 is provided on the moving block 24 and engages with the bidirectional screw 22, and a guide hole 242 is provided on the moving block 24 and is slidably connected to the guide rod 23. The two moving blocks 24 are symmetrically arranged relative to the middle of the bidirectional screw 22, and a light-emitting panel 61 is connected to the top of each moving block 24.

[0066] Through the design of the above structure, when the motor 21 is started, the bidirectional screw 22 will rotate accordingly, thereby driving the two moving blocks 24 to move relative to each other along the direction of the guide rod 23, so that the two light-emitting panels 61 respectively connected to the top of the two moving blocks 24 also move relative to each other; based on the above scheme, each light-emitting panel 61 only needs to be moved to the position corresponding to the middle of the first visual window 4 to complete the coverage of the first visual window 4, and there is no need to move the entire lighting assembly 6 from one end of the first visual window 4 to the other end to cover the entire visual window like a one-way movement. Therefore, the design method in this embodiment is more convenient and time-saving to use.

[0067] Furthermore, a storage battery may be provided on the light emitting board 61 to prevent the circuit from affecting the movement of the light emitting board 61 .

[0068] See attached Figure 1 and attached Figure 8 In order to be able to more comprehensively film the experimental operations of the training instructor, the following design is carried out in this embodiment. Specifically, the camera assembly 3 includes multiple cameras 31, and each camera 31 is connected to the experimental table 1 through a first metal shaped hose 7.

[0069] Through the design of the above structure, the experimental operation of the training instructor can be filmed from multiple angles through multiple cameras 31 in different positions, which is more comprehensive. The spatial position and shooting angle of the camera 31 can also be adjusted through the first metal shaping hose 7, making the shooting more flexible. For example, the camera can be zoomed in to take a close-up of an important operation, and the camera can be moved to the bottom of the experimental object to observe the experimental operation and chemical reaction process from different angles.

[0070] It should be noted that the camera assembly 3 and camera 31 in the present application are prior art, and presenting the captured video on the display screen 51 is also prior art, and its working principle will not be repeated here.

[0071] See attached Figure 1 and attached Figure 8 Furthermore, a microphone 18 can be provided on the chemical experiment training device so that students who are far away from the training instructor can also hear the instructor's explanation clearly; a second metal shaped hose 19 connected to the experimental table 1 can also be provided outside the microphone 18 to flexibly adjust the spatial position of the microphone 18.

[0072] See attached Figure 1 , Attachment Figure 4 , Attachment Figure 8 and attached Fig. 9 In order to make the chemical experiment training device more convenient to use, the following design is carried out in this embodiment. Specifically, a second chamber 102 is provided inside the experimental table 1, and the front side of the second chamber 102 is opened. The chemical experiment training device also includes a sink 8, a faucet 9, a waste liquid tank 10, and a limit assembly 11. The sink 8 is arranged on the top of the experimental table 1, and a drain pipe 82 is arranged at the bottom of the sink 8; the faucet 9 is installed on the top of the experimental table 1 and arranged corresponding to the sink 8, and the water inlet 91 of the faucet 9 can be connected to a water pipeline; a pulley is provided at the bottom of the waste liquid tank 10, and the top of the waste liquid tank 10 is opened. The waste liquid tank 10 can be moved into the second chamber 102, so that the liquid in the sink 8 can enter the interior of the waste liquid tank 10 through the drain pipe 82; the limit assembly 11, the limit assembly 11 is arranged on the experimental table 1, and is used to limit the waste liquid tank 10 inside the second chamber 102 to fix the relative position of the waste liquid tank 10 and the experimental table 1.

[0073] Through the design of the above structure, when water is needed for experiments, it can be connected through the faucet 9. When the instrument needs to be cleaned after the experiment, it can be rinsed through the faucet 9. The waste liquid after rinsing will enter the sink 8. Under the influence of gravity, the waste liquid in the sink 8 will enter the waste liquid tank 10 through the drain pipe 82, preventing the solution with impurities such as corrosive or pathogenic substances from being directly discharged into the sewer; when there is a lot of liquid in the waste liquid tank 10, the contact limit component 11 can limit the waste liquid tank 10, and the waste liquid tank 10 can be pulled out of the second chamber 102, so that the liquid in the waste liquid tank 10 is moved to a designated position for special cleaning.

[0074] See attached Figure 4 and attached Fig. 9 It should be noted that, since a drain pipe 82 is provided at the bottom of the water tank 8, a notch corresponding to the drain pipe 81 is obviously provided on the waste liquid tank 10 to prevent the movement of the waste liquid tank 10 from being affected.

[0075] See attached Figure 8 and attached Fig. 9 Furthermore, the bottom of the water tank 8 can be configured to be constricted so that the liquid in the water tank 8 can flow out through the drain pipe 82 more quickly and thoroughly.

[0076] See attached Figure 1 , Attachment Figure 4 and attached Figure 8 Based on the above scheme, in order to enable the limiting component 11 to limit the waste liquid tank 10 moved into the second chamber 102, the following design is carried out in this embodiment. Specifically, the limiting component 11 includes a first fixing member 111, a limiting member 112, and a second fixing member 113. The first fixing member 111 is arranged on the experimental table 1; the limiting member 112 is rotatably connected to the first fixing member 111, and the plane formed by the rotation of the limiting member 112 is located in the vertical plane. In the natural state, the lower end of the limiting member 112 corresponds to the second chamber 102 to prevent the waste liquid tank 10 from being separated from the second chamber 102; the second fixing member 113 is arranged on the experimental table 1, and the distance between the second fixing member 113 and the first fixing member 111 is less than the rotation radius of the limiting member 112. The direction of the connection line between the second fixing member 113 and the first fixing member 111 is arranged to intersect with the vertical line so that the limiting member 112 can be placed on the second fixing member 113.

[0077] Through the design of the above structure, when the waste liquid tank 10 is moved into the second chamber 102, the waste liquid tank 10 can only be pulled and moved in the direction away from the second chamber 102, and in the natural state, the lower end of the limit member 112 corresponds to the second chamber 102, so the limit member 112 can limit the movement of the waste liquid tank 10, thereby fixing the relative position of the waste liquid tank 10 and the laboratory table 1; and when releasing the limit, it is only necessary to rotate the limit member 112 and place it on the second fixing member 113, so that the waste liquid tank 10 can be pulled and moved in the direction away from the second chamber 102. In general, the limit assembly 11 in this embodiment has the advantages of simple structure and operation, reliable connection, etc.

[0078] See attached Figure 1 and attached Figure 4 After the waste liquid tank 10 is moved into the second chamber 102, the top of the waste liquid tank 10 is blocked, so the amount of liquid in the waste liquid tank 10 cannot be intuitively seen. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, a second visual window 12 is provided on the front of the waste liquid tank 10.

[0079] Through the design of the above structure, the liquid storage amount inside the waste liquid tank 10 can be conveniently observed.

[0080] Furthermore, the material of the first visual window 4 and the second visual window 12 can be selected to be high-pressure resistant observation window glass. This material has the following advantages, such as being able to withstand a certain pressure, being relatively thick, having high mechanical strength, high bending strength, high transparency, high visible light transmittance, excellent chemical stability, high electrical insulation and good heat shock resistance, etc.

[0081] See attached Figure 1 , Attachment Figure 8 , Attachment Fig.11 and attached Fig.12 Various impurities are often generated during chemical experiments. In order to prevent these impurities from directly entering the waste liquid tank 10 during the flushing process and causing problems in subsequent liquid treatment, the following design is carried out in this embodiment. Specifically, a first annular protrusion 81 is provided inside the water tank 8, and a solid filter assembly 13 is placed on the annular protrusion. The solid filter assembly 13 includes a box body 131, a second annular protrusion 132, and a handle 133. The top of the box body 131 is open, and the bottom of the box body 131 is provided with a plurality of filter holes 134; the second annular protrusion 132 is located outside the box body 131 and corresponds to the first annular protrusion 81. The bottom of the second annular protrusion 132 can abut the top of the first annular protrusion 81 to fix the relative position of the box body 131 and the water tank 8; the handle 133 is provided on the box body 131 to assist in taking and placing the solid filter assembly 13.

[0082] Through the design of the above structure, during the flushing of the experimental instrument, the waste liquid will first pass through the filter hole 134 at the bottom of the box body 131, and then enter the waste liquid tank 10 through the drain pipe 82. Therefore, the solid-liquid separation can be completed during the flow of the waste liquid, which is convenient for the targeted treatment of these impurities in the subsequent process; in addition, since the bottom of the second annular protrusion 132 is directly placed on the top of the first annular protrusion 81, and a handle 133 is provided on the box body 131, the solid filter assembly 13 can be easily disassembled and placed, which is more convenient to use.

[0083] See attached Figure 1 , Attachment Figure 2 and attached Fig.10 After the instrument is rinsed, if it is stored directly, it will be too humid. In order to solve the above problem, the following design is carried out in this embodiment. Specifically, it also includes a drain rack 14, and a cavity 141 is provided inside the drain rack 14. A plurality of drain holes 142 are provided on the top of the drain rack 14. The top of the cavity 141 is connected to the plurality of drain holes 142, and the side of the cavity 141 is connected to the sink 8.

[0084] Through the design of the above structure, after the instrument is rinsed, it can be placed on the drain rack 14 to dry. The water on the instrument will enter the cavity 141 through the drain hole 142 after falling. Since the side of the cavity 141 is connected to the sink 8, the liquid in the cavity 141 can also enter the sink 8 again, which can not only avoid water accumulation in the drain rack 14, but also uniformly recycle the waste liquid.

[0085] See attached Fig.10 Furthermore, in order to allow the liquid in the cavity 141 to enter the water tank 8 more quickly and thoroughly, the bottom of the cavity 141 can also be tilted so that the end of the bottom of the cavity 141 away from the water tank 8 is higher than the end of the bottom of the cavity 141 close to the water tank 8, so that the liquid falling to the bottom of the cavity 141 can quickly slide into the water tank 8 along the slope of the bottom of the cavity 141.

[0086] See attached Figure 1 In order to assist the experiment, the following design is also carried out in this embodiment. Specifically, a substantially rectangular ring-shaped edge 15 is provided on the top of the experimental table 1. A detachable baffle 16 is provided inside the edge 15. The baffle 16 is arranged corresponding to the water tank 8 to prevent objects on the experimental table 1 from falling into the water tank 8.
