Description

Technical Field

[0001] The present application belongs to the technical field of scent test paper fixation, and specifically relates to a magnetic fixation module for scent test paper. Background Art

[0002] During the research process of tobacco flavors, flavor researchers or formulators often need to evaluate the aroma and fragrance quality of various flavors and spices using flavor test papers. When evaluating flavors and spices adhered to the flavor test papers, the flavor test papers usually need to be inserted into a fixed rack so that flavor researchers and formulators can smell and evaluate them.

[0003] Currently, holders are typically long, rectangular structures with strip grooves along their length. To secure a scent test strip, one end of the strip is inserted into the strip groove, causing it to contact the groove wall, securing the strip. However, the long, rectangular structure of the holder makes it difficult to store and carry. Furthermore, if a flavor researcher or formulator places two adjacent strips too close together when inserting them into the strip groove, cross-contamination of aroma components can occur, affecting their evaluation of the fragrance. Utility Model Content

[0004] The present application provides a magnetic fixing module for fragrance test paper, so as to facilitate the storage and carrying of the fixing module, avoid cross-contamination of fragrance components, and ensure the accuracy of fragrance evaluation by fragrance researchers or formula researchers.

[0005] The technical solutions adopted in this application are:

[0006] A magnetic fixing module for scent test paper includes a main body, a connecting portion and a matching portion. The main body is provided with a fixing hole for inserting the scent test paper, and the main body has a first end and a second end opposite to the first end. The connecting portion is provided at the first end, and the matching portion is provided at the second end. The connecting portion and the matching portion can be magnetically matched to connect two adjacent magnetic fixing modules.

[0007] By adopting the above technical solution, when using the magnetic fixing module in the present application, the fragrance test paper dipped in the fragrance is inserted into the fixing hole, and then the fragrance test paper is pressed against the hole wall of the fixing hole to fix the fragrance test paper; if multiple fragrance test papers are to be fixed, multiple magnetic fixing modules are required, and the multiple magnetic fixing modules can be fixed together through the magnetic attraction of the connecting part and the matching part, or the multiple magnetic fixing modules can be placed separately to increase the flexibility of the magnetic fixing module; at the same time, only one fragrance test paper is inserted into each magnetic fixing module, which avoids cross-contamination of fragrance components and increases the accuracy of fragrance researcher or formula researcher's evaluation of fragrance; in addition, compared with the fixing rack in the prior art, the magnetic fixing module in the present application can arbitrarily place the required multiple magnetic fixing modules when storing or carrying it, so as to achieve the effect of facilitating the storage and carrying of the magnetic fixing module.

[0008] Optionally, the connecting portion is a magnetic piece provided at the first end, the matching portion is a matching piece provided at the second end, and the matching piece is ferromagnetic.

[0009] By adopting the above technical solution, when two magnetic fixing modules are spliced together, the first end of one of the magnetic fixing modules is placed opposite to the second end of the other magnetic fixing module, and then the two magnetic fixing modules are pushed toward each other so that the magnetic sheet and the matching sheet are magnetically attracted together, thereby realizing the splicing of two adjacent magnetic fixing modules, thereby increasing the connection stability of the two magnetic fixing modules.

[0010] Optionally, a connecting hole is provided at the first end, and a connecting column capable of matching with the connecting hole is provided at the second end corresponding to the connecting hole.

[0011] By adopting the above technical solution, when two magnetic fixing modules are spliced together, the first end of one of the magnetic fixing modules is placed opposite to the second end of the other magnetic fixing module, and then the two magnetic fixing modules are pushed toward each other so that the connecting column on one of the magnetic fixing modules extends into the connecting hole of the other magnetic fixing module, so as to realize the plug-in cooperation between the connecting column and the connecting hole to limit the two magnetic fixing modules, thereby increasing the connection stability of the two magnetic fixing modules.

[0012] Optionally, the connecting portion is a magnetic sheet provided in the connecting hole, and the connecting column has ferromagnetism, so that the connecting column constitutes the matching portion.

[0013] By adopting the above technical solution, since the connecting part is a magnetic sheet arranged in the connecting hole and the connecting column has ferromagnetism, the volume of the magnetic fixing module is reduced, so as to further achieve the effect of facilitating the storage and carrying of the magnetic fixing module. At the same time, when the connecting column on one magnetic fixing module is inserted into the connecting hole of another magnetic fixing module, the magnetic sheet and the connecting column automatically match magnetically.

[0014] Optionally, the second end is provided with an accommodating cavity, and at least a portion of the connecting column is located in the accommodating cavity and can move relative to the accommodating cavity.

[0015] By adopting the above technical solution, since the connecting column can move relative to the accommodating cavity, the connecting column can be completely hidden in the accommodating cavity, thereby reducing the volume of the magnetic fixing module, so as to further achieve the effect of facilitating the storage and carrying of the magnetic fixing module. At the same time, when the two magnetic fixing modules are spliced together, the connecting column can also automatically move toward the outside of the accommodating cavity under the action of the magnetic sheet and extend into the corresponding connecting hole.

[0016] Optionally, the accommodating cavity includes a first section and a second section located outside the first section, the inner diameter of the second section is smaller than the inner diameter of the first section, and the end of the connecting column is provided with a stop portion that can cooperate with the end wall stop of the first section.

[0017] By adopting the above technical solution, since the end of the connecting column is provided with a stop portion that can cooperate with the end wall stop of the first end, when the connecting column moves toward the outside of the accommodating cavity to the extreme position, the stop portion can cooperate with the end wall stop of the first section to avoid the possibility of the connecting column being separated from the accommodating cavity, thereby increasing the connection stability between the connecting column and the main body.

[0018] Optionally, the side of the body has an identification area for researchers to identify or mark.

[0019] By adopting the above technical solution, since the side of the main body has an identification area, researchers can identify the fragrance test paper through the distinguishing symbols in the identification area, or researchers can make identification marks on the identification area to avoid researchers' identification errors, thereby further increasing the accuracy of fragrance evaluation.

[0020] Optionally, the fixed hole has a first hole wall and a second hole wall opposite to the first hole wall, and the first hole wall is provided with an elastic member forming a fixed gap with the second hole wall, and the elastic member can elastically move relative to the second hole wall so that the width of the fixed gap can self-adjust according to the thickness of the fragrance test paper.

[0021] By adopting the above technical solution, when the scent test paper is inserted into the fixing hole, the scent test paper applies pressure to the elastic member, causing the elastic member to elastically move away from the second hole wall, so that the fixed gap is automatically adjusted according to the thickness of the scent test paper. At the same time, the elastic member elastically presses against the scent test paper, thereby increasing the stability of the scent test paper's fixation and preventing the scent test paper from being dislodged from the fixing hole due to other factors. In addition, the provision of the elastic member can also increase the diameter of the fixing hole, making it easier to insert the scent test paper into the fixing hole, thereby improving the efficiency of the insertion process.

[0022] Optionally, the elastic member is an elastic sheet, one end of the elastic sheet is connected to the first hole wall, and the elastic sheet is protruded toward the second hole wall.

[0023] By adopting the above technical solution, since the elastic sheet is protruding toward the second hole wall, after the test paper is inserted into the fixed hole, the elastic sheet can guide the test paper to move into the fixed gap, so that the elastic sheet can be pressed against the test paper to increase the fixing effect of the test paper.

[0024] Optionally, the first hole wall is provided with a mounting groove, one end of the elastic sheet is connected to the groove wall of the mounting groove, and the other end of the elastic sheet is located in the mounting groove.

[0025] By adopting the above technical solution, since one end of the elastic sheet is connected to the groove wall of the installation groove and the other end of the elastic sheet is located in the installation groove, the installation groove can block the end of the elastic sheet to avoid the situation where the end of the elastic sheet interferes with the test paper when the test paper is inserted into the fixing hole, thereby preventing the test paper from being inserted smoothly, thereby ensuring the fixing efficiency of the test paper.

[0026] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0027] 1. The magnetic fixing module in the present application includes a body, a connecting portion and a matching portion. The body is provided with a fixing hole for inserting the test scent paper. The body has a first end and a second end opposite to the first end. The connecting portion is provided at the first end and the matching portion is provided at the second end. The connecting portion and the matching portion can magnetically match to connect two adjacent magnetic fixing modules. When using the magnetic fixing module in the present application, the test scent paper dipped in fragrance is inserted into the fixing hole, and then the test scent paper is pressed against the hole wall of the fixing hole to fix the test scent paper. If multiple test scent papers are to be fixed, multiple magnetic fixing modules are required, and multiple magnetic fixing modules can be The magnetic fixing modules are fixed together by the magnetic attraction between the connecting part and the matching part, and multiple magnetic fixing modules can be placed separately to increase the flexibility of the magnetic fixing modules; at the same time, only one fragrance test paper is inserted in each magnetic fixing module, which avoids the cross-contamination of fragrance components and increases the accuracy of fragrance evaluation by fragrance researchers or formula researchers; in addition, compared with the fixing rack in the prior art, the magnetic fixing module in the present application can arbitrarily place multiple required magnetic fixing modules when storing or carrying it, so as to achieve the effect of facilitating the storage and carrying of the magnetic fixing modules.

The matching sheet has ferromagnetism. When two magnetic fixing modules are spliced together, the first end of one of the magnetic fixing modules is opposite to the second end of the other magnetic fixing module, and then the two magnetic fixing modules are pushed toward each other so that the magnetic sheet and the matching sheet are magnetically attracted together, thereby realizing the splicing of two adjacent magnetic fixing modules, thereby increasing the connection stability of the two magnetic fixing modules.

The first end in the present application is provided with a connecting hole, and the second end corresponding to the connecting hole is provided with a connecting column that can be adapted to the connecting hole.

[0042] Reference Figures 1 to 4 , discloses a magnetic fixing module for scent test paper, which includes a main body 1, a connecting part 2 and a matching part 3. The main body 1 is provided with a fixing hole 11 for inserting the scent test paper, and the main body 1 has a first end and a second end opposite to the first end, the connecting part 2 is provided at the first end, and the matching part 3 is provided at the second end. The connecting part 2 and the matching part 3 can be magnetically matched to connect two adjacent magnetic fixing modules.

[0043] It can be understood that the main body 1 has a length direction, a width direction perpendicular to the length direction, and a height direction perpendicular to the length direction and the width direction, and the height direction piece is arranged parallel to the plumb bob direction, the axial direction of the fixing hole 11 is arranged parallel to the height direction, and the two ends of the length direction of the main body 1 form a first end and a second end respectively.

[0044] When using the magnetic fixing module in the present application, the fragrance test paper dipped in fragrance is inserted into the fixing hole 11, and then the fragrance test paper is made to contact the hole wall of the fixing hole 11 to fix the fragrance test paper; if multiple fragrance test papers are to be fixed, multiple magnetic fixing modules are required, and the multiple magnetic fixing modules can be fixed together through the magnetic attraction of the connecting part 2 and the matching part 3, or the multiple magnetic fixing modules can be placed separately to increase the flexibility of the magnetic fixing module.

[0045] At the same time, only one fragrance test paper is inserted in each magnetic fixing module, which avoids cross-contamination of fragrance components and increases the accuracy of fragrance evaluation by fragrance researchers or formula researchers; in addition, compared with the fixing racks in the prior art, the magnetic fixing modules in this application can be placed arbitrarily when they are stored or carried, so as to facilitate the storage and carrying of the magnetic fixing modules.

[0046] The present application does not make any specific limitation on the structure of the connecting portion 2 and the matching portion 3. Preferably, refer to Figure 1The connecting portion 2 is a magnetic piece provided at the first end, and the matching portion 3 is a matching piece provided at the second end, and the matching piece has ferromagnetism.

[0047] Specifically, when two magnetic fixing modules are spliced together, the first end of one of the magnetic fixing modules is aligned with the second end of the other magnetic fixing module, and then the two magnetic fixing modules are pushed toward each other so that the magnetic sheet and the mating sheet are magnetically attracted together, thereby achieving the splicing of two adjacent magnetic fixing modules, thereby increasing the connection stability of the two magnetic fixing modules.

[0048] In other embodiments, the connecting portion 2 may be a magnetic sheet provided at the first end, and the mating portion 3 may also be a magnetic sheet provided at the second end. When the connecting portion 2 on one magnetic fixing module is opposite to the mating portion 3 on another magnetic fixing module, the magnetic poles of the two are opposite, so that the two can attract each other and be magnetically mated together.

[0049] In a preferred embodiment, referring to Figures 1 to 3 A connecting hole 12 is provided at the first end, and a connecting column 13 that can adapt to the connecting hole 12 is provided at the second end corresponding to the connecting hole 12.

[0050] Specifically, when two magnetic fixing modules are spliced together, the first end of one of the magnetic fixing modules is aligned with the second end of the other magnetic fixing module, and then the two magnetic fixing modules are pushed toward each other so that the connecting column 13 on one of the magnetic fixing modules extends into the connecting hole 12 of the other magnetic fixing module, so as to realize the plug-in fit of the connecting column 13 and the connecting hole 12 to limit the two magnetic fixing modules, thereby increasing the connection stability of the two magnetic fixing modules.

[0051] Further, refer to Figure 3 The connecting part 2 is a magnetic sheet arranged in the connecting hole 12, and the connecting column 13 is ferromagnetic, so that the connecting column 13 constitutes the matching part 3, thereby reducing the volume of the magnetic fixing module, so as to further achieve the effect of facilitating the storage and carrying of the magnetic fixing module. At the same time, when the connecting column 13 on one magnetic fixing module is inserted into the connecting hole 12 of another magnetic fixing module, the magnetic sheet and the connecting column 13 automatically match magnetically.

[0052] The present application does not specifically limit the material of the connecting pillar 13. Preferably, the connecting pillar 13 is made of iron material to reduce the production cost of the connecting pillar 13. In other embodiments, the connecting pillar 13 can also be made of other ferromagnetic materials, such as cobalt, nickel and other metals.

[0053] Further, refer to Figure 3The second end is provided with an accommodating cavity 131 , and at least a portion of the connecting column 13 is located in the accommodating cavity 131 and can move relative to the accommodating cavity 131 .

[0054] It can be understood that the depth of the accommodating cavity 131 is greater than or equal to the length of the connecting column 13, so that the connecting column 13 can be completely hidden in the accommodating cavity 131 to reduce the volume of the magnetic fixing module, so as to further achieve the effect of facilitating the storage and carrying of the magnetic fixing module. At the same time, when the two magnetic fixing modules are spliced together, the connecting column 13 can also automatically move toward the outside of the accommodating cavity 131 under the action of the magnetic sheet and extend into the corresponding connecting hole 12.

[0055] Further, refer to Figure 3 The accommodating cavity 131 includes a first section 132 and a second section 133 located outside the first section 132. The inner diameter of the second section 133 is smaller than the inner diameter of the first section 132. The end of the connecting column 13 is provided with a stop portion 134 that can cooperate with the end wall stop of the first section 132. When the connecting column 13 moves toward the outside of the accommodating cavity 131 to the extreme position, the stop portion 134 can cooperate with the end wall stop of the first section 132 to avoid the connection column 13 from being separated from the accommodating cavity 131, thereby increasing the connection stability between the connecting column 13 and the body 1.

[0056] The present application does not specifically limit the structure of the stopper 134. Preferably, refer to Figure 3 The stopper 134 is an annular structure provided at the end of the connecting post 13 to increase the area of engagement between the stopper 134 and the end wall of the first section 132, thereby enhancing the retaining effect on the connecting post 13. In other embodiments, the stopper 134 may also be a rod-shaped structure fixedly connected to the connecting post 13 and extending through the body 1. In other words, a waist-shaped groove is provided on the body 1 corresponding to the rod-shaped structure, and the rod-shaped structure is positioned in the waist-shaped groove.

[0057] Furthermore, a guide surface is provided at the end of the connecting column 13 away from the main body 1, and the guide surface extends along the circumference of the connecting column 13 to reduce the diameter of the end of the connecting column 13 away from the main body 1, thereby achieving the effect of facilitating the insertion of the connecting column 13 into the connecting hole 12.

[0058] Furthermore, a transition surface is provided at the opening of the connecting hole 12 , and the transition surface is extended along the circumference of the connecting hole 12 to increase the opening diameter of the connecting hole 12 , thereby achieving the effect of facilitating the insertion of the connecting column 13 into the connecting hole 12 .

[0059] In a preferred embodiment, referring to Figure 1 and Figure 2The side of the body 1 has an identification area 14 for researchers to identify or mark, so that researchers can identify the test paper through the distinguishing symbols in the identification area 14, or researchers can make identification marks on the identification area to avoid researchers' identification errors, thereby further increasing the accuracy of fragrance evaluation.

[0060] The present application does not specifically limit the structure of the identification area 14. Preferably, the identification area 14 is an identification symbol engraved or affixed to the side of the body 1, such as the letters A, B, C, D, the numbers 1, 2, 3, 4, etc., to facilitate researchers to record different test strips. In other embodiments, the identification area 14 can also be a paint provided on the side of the body 1 for researchers to mark symbols, or the identification area 14 can be a paper slot provided on the side of the body 1, so that researchers can insert a label that distinguishes the test strips into the paper slot.

[0061] In a preferred embodiment, referring to Figure 4 The fixed hole 11 has a first hole wall and a second hole wall opposite to the first hole wall. The first hole wall is provided with an elastic member 4 forming a fixed gap with the second hole wall. The elastic member 4 can elastically move relative to the second hole wall so that the width of the fixed gap can be self-adjusted according to the thickness of the fragrance test paper.

[0062] Specifically, when the scent test paper is inserted into the fixing hole 11, the scent test paper applies pressure to the elastic member 4, causing the elastic member 4 to elastically move away from the second hole wall. This automatically adjusts the fixed gap according to the thickness of the scent test paper. At the same time, the elastic member 4 elastically presses against the scent test paper, thereby increasing the stability of the scent test paper's fixation and preventing the scent test paper from being affected by other factors and falling out of the fixing hole 11. Furthermore, the provision of the elastic member 4 can also increase the diameter of the fixing hole 11, making it easier to insert the scent test paper into the fixing hole 11, thereby improving the efficiency of inserting the scent test paper into the fixing hole 11.

[0063] The structure of the elastic member 4 is not specifically limited in the present application. Preferably, the elastic member 4 is an elastic sheet, one end of which is connected to the first hole wall, and the elastic sheet protrudes toward the second hole wall.

[0064] That is to say, the elastic member 4 is a bent elastic sheet. After the scent test paper is inserted into the fixing hole 11, the elastic sheet can guide the scent test paper so that the scent test paper moves into the fixed gap, so that the elastic sheet can be pressed against the scent test paper to increase the fixing effect of the scent test paper.

[0065] Further, refer to Figure 4The first hole wall is provided with a mounting groove 15, one end of the elastic sheet is connected to the groove wall of the mounting groove 15, and the other end of the elastic sheet is located in the mounting groove 15, so that the mounting groove 15 can block the end of the elastic sheet to avoid the end of the elastic sheet interfering with the test paper when the test paper is inserted into the fixing hole 11, thereby affecting the smoothness of the insertion of the test paper, thereby ensuring the fixing efficiency of the test paper.

[0066] Preferably, the fixing hole 11 penetrates the main body 1 in the height direction of the main body 1, so that the fragrance test paper can be inserted regardless of whether the main body 1 is placed upright or upside down.

[0067] In other embodiments, the elastic member 4 may also be a block-shaped structure made of rubber material.

[0068] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0069] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on the differences from other embodiments.

[0070] The foregoing is merely an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations.
