[0034] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work should fall within the scope of protection of this application.
[0035] At present, the waterproof level of experimental instruments such as magnetic stirrers can only reach IP21, which leads to certain safety hazards. The main reason is that it is impossible to ensure the internal waterproofness of the instrument without affecting the heat dissipation performance.
[0036] In order to solve the above problems, the applicant has developed an experimental instrument, on the support surface of which a new type of bearing component waterproof mounting structure is installed. The bearing component waterproof mounting structure can effectively improve the waterproof performance of the instrument support surface and prevent liquid splashed from the surface of the bearing component during the experiment from entering the support surface and affecting the main board and circuits of the instrument.
[0037] Specifically, see Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the explosion structure of an embodiment of the instrument of the present application. Figure 2 It is a schematic cross-sectional structure diagram of an embodiment of the instrument of the present application.
[0038] like Figure 1 and Figure 2 As shown, the instrument includes a support surface 100 for installing a work surface, and a support member 200 waterproof installation structure is arranged on the support surface 100. The support member 200 waterproof installation structure includes a support member 200 and an isolation member 300. The support member 200 is located above the support surface 100 of the instrument, and the isolation member 300 is arranged between the support member 200 and the support surface 100.
[0039] The carrier 200 may include a bearing surface for placing a container in the experiment. Since the container contains liquid during the experiment, there is a risk of the liquid splashing onto the surface or periphery of the carrier 200. In order to prevent the liquid from directly entering the gap 203 between the carrier 200 and the isolation member 300, the carrier 200 includes a first water guide ring 201 arranged on the periphery. The first water guide ring 201 extends from the carrier 200 along the first direction Z1. The first direction Z1 is the direction from the carrier 200 to the support surface 100.
[0040] Furthermore, in order to guide the liquid flowing along the first water guide ring 201 to the outside of the support surface 100 , a second water guide ring 301 and a third water guide ring 302 are arranged on the outer periphery of the isolation member 300 .
[0041] The third water guide ring 302 extends from the isolation member 300 along the second direction Z2 to the inside of the first water guide ring 201, and the second water guide ring 301 extends from the isolation member 300 along the first direction Z1 to the outside of the support surface 100. The second direction Z2 is the direction from the support member 200 to the support surface 100.
[0042] It can be understood that since the third water guide ring 302 extends to the inner side of the first water guide ring 201, the liquid flowing through the first water guide ring 201 can flow to the surface of the third water guide ring 302, and flow through the surface of the third water guide ring 302 to the surface of the second water guide ring 301, and finally flow to the outside of the support surface 100, effectively avoiding the liquid entering the support surface 100 and affecting the main board and circuits of the instrument.
[0043] Furthermore, in order to realize the diversion of liquid on the surface of the third water guide ring 302 and the second water guide ring 301, in this embodiment, the diameter of the third water guide ring 302 gradually increases along the second direction Z2, and the diameter of the second water guide ring 301 gradually increases along the first direction Z1. Of course, in other embodiments, the diameters of the third water guide ring 302 and the second water guide ring 301 can also remain unchanged along the vertical direction, or the diameter of the third water guide ring 302 gradually decreases along the second direction Z2, and the diameter of the second water guide ring 301 gradually decreases along the first direction Z1, ensuring that the third water guide ring 302 extends to the outside of the first water guide ring 201, and the second water guide ring 301 extends to the outside of the support surface 100, and the effects of this embodiment can be achieved.
[0044] It should be noted that the function of the third water guide ring 302 in the above structure is to guide the liquid passing through the first water guide ring 201 to the second water guide ring 301. In some embodiments, the third water guide ring 302 can also be omitted. Through the guiding effect of the first water guide ring 201, the liquid can fall freely to the surface of the second water guide ring 301, which can also achieve a certain waterproof effect.
[0045] In this embodiment, the instrument can be an instrument with heating capability, such as a heating magnetic stirrer. A circle of heating tubes 202 is arranged on the side of the carrier 200 facing the isolation member 300. The heating tubes 202 are used to heat the container placed on the surface of the carrier 200.
[0046] In order to improve the thermal insulation between the carrier 200 and the instrument support surface 100, the isolation member 300 of this embodiment includes a first isolation plate 303 and a second isolation plate 304 stacked along a first direction Z1, the third water guide ring 302 can be arranged around the first isolation plate 303, and the second water guide ring 301 can be arranged around the second isolation plate 304.
[0047] In the split design of the above-mentioned isolation member 300 , the splashed liquid will flow along the third water guide ring 302 to the joint between the first isolation plate 303 and the second isolation plate 304 , and then flow to the surface of the second water guide ring 301 .
[0048] To prevent liquid from entering the gap between the first isolation plate 303 and the second isolation plate 304, refer to Figure 3 , Figure 3 yes Figure 2 In the partially enlarged schematic diagram of center A, in this embodiment, a flange 3031 is arranged on the outer edge of the first isolation plate 303, the third water guide ring 302 extends from the outer edge of the flange 3031 along the second direction Z2, and the second water guide ring 301 extends from the outer edge of the second isolation plate 304 along the first direction Z1 from the inner side of the flange 3031 to the outer side of the flange 3031.
[0049] It is understandable that due to the existence of the flange 3031, the gap between the first isolation plate 303 and the second isolation plate 304 is completely covered, and the liquid flows directly to the surface of the third water guide ring 302 after flowing through the first water guide ring 201 to the outer edge of the flange 3031, thereby further improving the waterproof performance.
[0050] In this embodiment, in order to improve the overall waterproof performance, the first isolation plate 303, the flange 3031 and the third water guide ring 302 are integrally formed stainless steel plates.
[0051] In other embodiments, the first isolation plate 303, the flange 3031 and the third water guide ring 302 may also be made of other materials, or, the first isolation plate 303, the flange 3031 and the third water guide ring 302 may also be designed in a split style, and the materials of the first isolation plate 303, the flange 3031 and the third water guide ring 302 may also be different, as long as the waterproof performance of the connection between the first isolation plate 303, the flange 3031 and the third water guide ring 302 is guaranteed, and the effect of the present embodiment can be achieved.
[0052] In addition, in order to prevent liquid from entering between the first isolation plate 303 and the second isolation plate 304 from between the flange 3031 and the second water guide ring 301, the gap width H between the flange 3031 and the second water guide ring 301 in this embodiment is less than 0.2 mm. Of course, in some embodiments, the flange 3031 and the second water guide ring 301 can also be closely arranged to prevent liquid from entering between the flange 3031 and the second water guide ring 301.
[0053] In this embodiment, in order to prevent liquid from splashing onto the heating tube 202, the heating tube 202 can be arranged on the inner side of the first water guide ring 201, and the heating tube 202 and the first water guide ring 201 can form a gap 203, and the third water guide ring 302 can extend into the gap 203 to achieve a waterproof design for the heating tube 202.
[0054] In this embodiment, the support surface 100 of the instrument is also arranged with electrical components 101 such as chips and circuit boards. In order to realize the avoidance design of the isolation member 300 for the electrical components 101 and ensure the isolation between the electrical components 101 and the carrier 200, the second isolation plate 304 is also arranged with avoidance holes 3041 for the electrical components 101 to pass through, and the first isolation plate 303 is arranged with a recessed portion 3032 on the side facing the second isolation plate 304.
[0055] The recessed portion 3032 forms an installation cavity 305 for inserting the electric component 101 , so that the electric component 101 in the installation cavity 305 can be isolated from the carrier 200 .
[0056] Currently, in other embodiments, a recessed area can be arranged on the side of the second isolation plate 304 facing the support surface 100, and correspondingly, an opening to avoid the recessed area can be arranged on the first isolation plate 303, or recessed areas can be arranged on both the second isolation plate 304 and the first isolation plate 303 to achieve avoidance installation of the electrical component 101, which can also achieve the effect of this embodiment.
[0057] In order to improve the waterproof performance while ensuring the heat dissipation performance inside the instrument, such as Figure 2 As shown, in this embodiment, a heat dissipation gap 400 is formed between the first water guide ring 201 and the third water guide ring 302 , and between the second water guide ring 301 and the support surface 100 .
[0058] In order to form the heat dissipation gap 400 and further improve the isolation between the carrier 200 and the instrument support surface 100, in this embodiment, the carrier 200 can be spaced apart from the isolation member 300, and the isolation member 300 can be spaced apart from the instrument support surface 100.
[0059] Specifically, Figure 1 As shown, the carrier 200, the first isolation plate 303, the second isolation plate 304 and the instrument support surface 100 can be fixed by positioning bolts, and a plurality of first positioning bolts 500 can be fixed by a threaded structure on the side of the carrier 200 facing the first isolation plate 303, and a screw hole can be arranged on the end surface of the first positioning bolt 500 facing away from the carrier 200; a plurality of second positioning bolts 600 can be arranged through the first isolation plate 303 and the second isolation plate 304, and the second positioning bolts 600 can be arranged one by one with the first positioning bolts 500, and one end of the second positioning bolt 600 is fixed to the first positioning bolt 500, and the other end is fixed to the instrument support surface 100, thereby realizing the spaced installation arrangement of the three and ensuring the formation of the heat dissipation gap 400.
[0060] In other embodiments, other structures may also be used to achieve the spaced installation of the carrier 200 and the isolation member 300 and the spaced installation of the isolation member 300 and the instrument support surface 100. For example, positioning columns may be arranged on both sides of the isolation member 300 so that the two ends of the positioning columns are respectively fixed to the carrier 200 and the support surface 100, etc., which can also achieve the effect of the present embodiment.
[0061] In addition, in this embodiment, in order to facilitate the positioning and installation of the isolation member 300, the support surface 100 of the instrument is also arranged with a positioning boss 102, and the first isolation plate 303 and the second isolation plate 304 are arranged with positioning holes 306 matching the positioning boss 102 to facilitate the installation and fixation of the first isolation plate 303 and the second isolation plate 304.
[0062] Based on the waterproof installation structure of the carrier 200 in the above-mentioned embodiments, when liquid splashes out from the surface of the carrier 200, the liquid can flow along the first water guide ring 201, the third water guide ring 302, and the second water guide ring 301 in sequence to the outside of the support surface 100 of the instrument, thereby preventing the liquid from flowing into the interior of the instrument, effectively improving the waterproof performance of the interior of the instrument, and the waterproof grade can reach IP32. In addition, daily cleaning and maintenance only requires cleaning the external surface of the instrument, which is easy to clean and maintain.
