Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a mercury collection device for a thermometer. Background Technology

[0002] Thermometers are commonly used tools for measuring temperature, but traditional mercury thermometers are prone to leaking mercury due to breakage. Mercury is a toxic heavy metal, and if not collected promptly and effectively, it can cause serious harm to the environment and human health.

[0003] Authorization announcement number CN222361331U discloses a mercury collection device, relating to the field of medical device technology. This mercury collection device includes: a collection box with an opening at the top for storing mercury; and a lid that fits into the opening of the collection box for sealing. The device collects mercury by rolling an adsorbent on a roller to adhere to and collect it. However, in practical applications, due to the smooth surface of the adsorbent, the friction between the adsorbent and the mercury is low when dealing with large amounts of mercury, making it unable to effectively bind the mercury. In this case, the rotating adsorbent pushes the mercury to other areas, further expanding the mercury contamination area, increasing the difficulty of mercury collection, and potentially causing more areas to become contaminated with mercury, affecting the effectiveness and safety of this type of mercury collection device.

[0004] In summary, it is necessary to develop a mercury collection device with high-efficiency adsorption performance to meet the requirements of emergency treatment of mercury pollution. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problems of the above-mentioned mercury collection device for thermometers, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a mercury collection device for a thermometer, including a roller;

[0008] A rubber sleeve, with a key sleeve located outside the roller, includes:

[0009] The slits are evenly distributed around the circumference of the rubber sleeve, and the inner walls on both sides of the slits are forced to deform and come together by the rolling and squeezing of the rubber sleeve.

[0010] The adhesive sheet has a semi-open cross-section and is embedded inside the slit, with its outer wall always adhering to the inner wall of the slit.

[0011] When the rubber sleeve rolls to collect mercury, the slit forms a diffusion channel to guide the mercury, and the two inner walls of the adhesive sheet are driven by the slit to come together to adhere the mercury in the diffusion channel.

[0012] In a preferred embodiment of the mercury collection device for a thermometer described in this utility model, the width of the plurality of slits alternates along the circumference of the rubber sleeve, and the width of adjacent slits alternately increases and decreases along the axial direction of the rubber sleeve, thereby forming an alternating rotational guidance for the mercury.

[0013] In a preferred embodiment of the mercury collection device for a thermometer described in this utility model, the gap between the two side walls of the adhesive strip decreases linearly from its opening inwards, thereby increasing the contact area between the mercury and the interior of its two side walls.

[0014] In a preferred embodiment of the mercury collection device for a thermometer described in this utility model, the gap between the two side walls of the adhesive plate increases linearly along the length of the slit, and the gap is positively correlated with the opening width of the slit.

[0015] In a preferred embodiment of the mercury collection device for a thermometer described in this utility model, a guide block is fixed at the largest opening end of the slit. The guide block has a triangular cross-section, and the gap between the guide block and the inner walls on both sides of the slit decreases along the depth of the slit.

[0016] As a preferred embodiment of the mercury collection device for a thermometer described in this utility model, the collection device further includes a cover and a body. The bottom of the cover is fixed with a connecting frame that is rotatably connected to a roller. The body can be threadedly connected to the cover to form a sealed space that seals the rubber sleeve.

[0017] The beneficial effects of this invention are as follows: The rubber sleeve fitted over the roller enables efficient collection and pollution control of spilled mercury. As the rubber sleeve rolls under the roller's influence, the slits distributed around its surface create directional channels for the spilled mercury, guiding it along a predetermined path and precisely controlling its diffusion direction, significantly reducing the risk of contamination. Simultaneously, the rubber sleeve undergoes elastic deformation during rolling and compression, causing the inner walls of the slits to come closer together, which in turn causes the adhesive pads embedded within the slits to tighten synchronously. This dynamic process significantly increases the contact area between the adhesive pads and the diffused mercury, enhancing adhesion and achieving efficient adsorption and collection of mercury.

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Reference Figures 1-5 As an embodiment of the present invention, a mercury collection device for a thermometer is provided, which includes a roller 1, providing a stable rotational basis for the rolling of the rubber sleeve 2.

[0030] The rubber sleeve 2, with its key sleeve located outside the roller 1, deforms during the rolling and extrusion process due to its own elasticity.

[0031] The slits 21 are equidistantly distributed around the circumference of the rubber sleeve 2, forming diffusion channels for mercury during the rolling of the rubber sleeve 2. The inner walls on both sides of the slits 21 are forced to deform and converge after being squeezed by the rolling of the rubber sleeve 2. The width of the multiple slits 21 varies alternately along the circumference of the rubber sleeve 2, and the width of adjacent slits 21 alternately increases and decreases along the axial direction of the rubber sleeve 2, forming an alternating rotational guidance for the mercury. Thus, the slits 21 with larger slit widths can guide the diffusion of larger volumes of mercury, while the slits 21 with smaller slit widths can guide the diffusion of smaller volumes of mercury, improving the applicability to mercury of different volumes and further improving the collection efficiency of mercury.

[0032] A guide block 23 is fixed at the largest opening end of the slit 21. The cross-section of the guide block 23 is triangular, and the gap between it and the inner walls on both sides of the slit 21 decreases along the depth of the slit 21. It can guide and collect the mercury entering the slit 21, help the mercury to enter the interior of the slit 21 smoothly, and move towards the adhesive plate 22, making the mercury easier to be adsorbed by the adhesive plate 22, and further improving the collection effect.

[0033] The adhesive plate 22 has a semi-open cross-section and can be made of mercury adsorption material containing sulfur or activated carbon. It can chemically bind mercury (e.g., to form mercury sulfide). It is embedded inside the slit 21, and its outer wall always adheres to the inner wall of the slit 21. The gap between the two side walls of the adhesive plate 22 decreases linearly from its opening inward to increase the contact area between the inner side walls and mercury. The gap between the two side walls of the adhesive plate 22 increases linearly along the length of the slit 21, and the gap is positively correlated with the opening width of the slit 21. The inward narrowing structure of the opening of the adhesive plate 22 can increase its contact area with mercury, thereby improving the adhesion effect of mercury. At the same time, the gap between its two side walls widens synchronously when the slit width of the slit 21 increases, thereby increasing the space for contact with mercury and improving the collection efficiency.

[0034] When the rubber sleeve 2 rolls to collect mercury, the slit 21 forms a diffusion channel to guide the mercury, and the two inner walls of the adhesive sheet 22 are driven by the slit 21 to come together to adhere the mercury in the diffusion channel, thereby achieving a highly efficient mercury collection effect and effectively preventing the mercury from spreading outward during the collection process, thus reducing the scope of pollution.

[0035] The collection device also includes a lid 3 and a body 4. The bottom of the lid 3 is fixed with a connecting frame 31 that is rotatably connected to the roller 1. The body 4 can be threadedly connected to the lid 3 to form a sealed space of a sealing rubber sleeve 2, which prevents the collected mercury from evaporating and also prevents external impurities from entering and affecting the performance of the device.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
