Description

Technical Field

[0002] Food safety has become a focus of social attention. To ensure food safety, food must be sampled and tested during the market circulation process after production, and sampling is a crucial link in the entire testing process. The traditional sampling method usually involves cutting the food first and then storing the cut samples in a special container. In actual operation, testers often need to sample different parts of the food, that is, extract multiple samples from the same food, in order to improve the accuracy of the test results by comparing the test data of multiple samples.

[0003] However, traditional sampling methods face certain challenges for some highly viscous foods, such as glutinous rice, glutinous rice balls, rice dumplings, and rice cakes. These foods are soft and easily deformed, which leads to irregular shapes during the sampling process, making it difficult to uniformly control the quality and volume of different samples. In order to ensure the consistency of sample size, multiple sampling and adjustments are often required, which not only increases the difficulty of operation, but also affects the sampling efficiency, which in turn has a potential impact on the accuracy of the test results.

DETAILED DESCRIPTION

[0047] The following will be combined with the accompanying drawings in 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.

[0048] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0049] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0050] See also Figure 1 and Figure 2 As shown, one of the purposes of the present invention is to provide a sampler for detecting viscous food, comprising a housing 100, the housing 100 is a tubular structure with two ends connected, and as shown Figure 2 As shown, the diameter of the bottom of the housing 100 is larger than the diameter of the top, that is, the upper half of the housing 100 (preferably occupying two-thirds of the entire length of the housing 100) is thin, and the lower half (preferably occupying one-third of the entire length of the housing 100) is thick. In this way, it is convenient for the staff to hold the upper half of the housing 100, and the lower half of the housing 100 can accommodate larger food.

[0051] A first partition 101 is fixedly provided inside the thicker part of the shell 100, and a plurality of shaping components 120 arranged in a circular array with the center of the bottom end of the shell 100 as the center point are provided at the bottom of the first partition 101; the plurality of shaping components 120 are enclosed inside the bottom end of the shell 100 to form a shaping area 102 for food to enter, and separate their own exterior from the inner circle of the shell 100 into a storage cavity 103; at the same time, the plurality of shaping components 120 can be closed and dispersed to change the size of the shaping area 102, and are used to extrude and shape the food in the shaping area 102 so that the shape of the food corresponds to the shape of the shaping area 102.

[0052] A driving mechanism for driving the multiple shaping components 120 to close and disperse is provided on the top of the first partition 101; a sampling component 130 is rotatably provided on the side wall of the shaping component 120, and a part of the sampling component 130 is located in the shaping area 102, and the other part is located in the storage cavity 103; when the multiple shaping components 120 are closed, the sampling component 130 uses the position change of the shaping component 120 to perform a rotational motion, so as to take part of the food in the shaping area 102 into the storage cavity 103 for storage during the rotation.

[0053] like Figure 3As shown, the shaping component 120 includes an extrusion plate 121 disposed inside the housing 100 and below the first partition 101. The interior of the plurality of extrusion plates 121 forms a shaping area 102, and the storage cavity 103 is formed between the exterior and the inner wall of the housing 100. The extrusion plate 121 can be in a straight state of a "I" shape, a bent state of a "V" shape, or an arc state. For example, when the number of the extrusion plates 121 is four:

[0054] If the extrusion plate 121 is in a straight state in the shape of a letter "I", then the multiple extrusion plates 121 are closed to form a square tubular structure; if the extrusion plate 121 is in a bent state in the shape of a letter "V", then the multiple extrusion plates 121 are closed to form a diamond-shaped tubular structure; if the extrusion plate 121 is in an arc state, then the multiple extrusion plates 121 are closed to form a circular tubular structure. Figure 3 In the illustrated embodiment, the extrusion plate 121 is in an arc shape, and the bottom end of the extrusion plate 121 is bent toward the outer circle of the housing 100 to form a bottom plate 122 to seal the bottom of the storage cavity 103 .

[0055] When the multiple extrusion plates 121 are dispersed, there will be gaps between the multiple extrusion plates 121, thereby affecting the sealing of the storage chamber 103. At the same time, the extrusion plates 121 are also prone to cutting off the food during the closing process. To this end, the present invention fills the gaps. Specifically, multiple blocking blocks 104 are fixedly arranged on the inner ring of the housing 100. The blocking blocks 104 are located in the gaps generated when the multiple extrusion plates 121 are dispersed, and the side walls of the blocking blocks 104 are in contact with the ends of the extrusion plates 121.

[0056] Figure 4 and Figure 5 The specific structure of the sampling assembly 130 is shown. As shown in the figure, the sampling assembly 130 includes a longitudinally arranged sampling rod 131, and the outer circle of the sampling rod 131 is partially recessed inward to form a sampling groove 132 in the longitudinal direction. The sampling rod 131 can be a cylindrical structure with equal diameters at the upper and lower ends, or a conical structure with a large bottom diameter and a small bottom diameter (or a small bottom diameter and a large bottom diameter); when the sampling rod 131 is a cylindrical structure, the depths of the sampling groove 132 at different positions are all in an equal state; when the sampling rod 131 is a conical structure, the depth of one end of the sampling groove 132 is greater than the depth of the other end (refer to Fig.11 ), which can realize taking different amounts of food at different heights. In addition, the sampling rod 131 rotates in the through slot 125 of the side wall of the squeezing plate 121, and the through slot 125 penetrates the side wall of the squeezing plate 121. The diameter of the sampling rod 131 is greater than the thickness of the squeezing plate 121. At this time, a part of the sampling rod 131 can be in the shaping area 102, and the other part can be in the storage cavity 103.

[0057] To sample by the sampling slot 132, the sampling rod 131 is required to drive the sampling slot 132 to rotate in the shaping area 102, and a portion of the food in the shaping area 102 is taken out by the rotation. Figure 4 As shown, when the sampling rod 131 is a conical structure, the present invention performs a planar processing on the outer ring of the top of the sampling rod 131, that is, a cylinder is set on the outer ring of the top of the sampling rod 131, and the outer ring of the cylinder is in a planar state in a cross-section state, so as to improve the fit with the driving wheel 133 to be described below. Then a driving wheel 133 is set to contact the top plane of the sampling rod 131, and the driving wheel 133 is rotatably connected to the top of the sampling rod 131. The top of the driving wheel 133 is coaxially fixed with a shaft rod 134, and the outer ring of the shaft rod 134 is rotatably provided with a connecting block connected to the side wall of the extrusion plate 121 (refer to Figure 4 In addition, the top of the shaft 134 extends into the chute 124 opened at the top of the first partition 101, and the diameter of the shaft 134 is smaller than the width of the chute 124, and one side of the shaft 134 is frictionally connected to one side of the chute 124. It should be noted that when the multiple extrusion plates 121 are in a dispersed state, the sampling slot 132 is located in the storage cavity 103.

[0058] At the same time, the rotational connection between the sampling rod 131 and the driving wheel 133 mentioned above, and the frictional connection between the shaft 134 and the side wall of the slide groove 124 can also be in a meshing manner. For example, a tooth groove is provided on the top outer ring of the sampling rod 131, and a tooth block meshing with the tooth groove is provided on the outer ring of the driving wheel 133; a tooth block is provided on the outer ring of the top end of the shaft 134, and a tooth groove meshing with the tooth block is provided on the side wall of the slide groove 124. In this way, the transmission accuracy can be maintained even after long-term use.

[0059] The driving mechanism can be electrically driven, that is, a motor or a telescopic rod is used to drive the extrusion plate 121 to move, so as to achieve the closing or dispersing operation. At the same time, a manual method can also be used, for example, Figure 2-Figure 4 In the embodiment shown:

[0060] The slide groove 124 is set through the first partition 101, and the top of the extrusion plate 121 is fixedly provided with a driven block 123 that passes through the slide groove 124; then, the driving mechanism includes a turntable 112 that is rotatably set on the top of the first partition 101, and the top of the turntable 112 is provided with a through guide groove 113, and the top of the driven block 123 penetrates into the guide groove 113. At the same time, the guide groove 113 is inclined, so that the position of the driven block 123 in the slide groove 124 can be changed by the guide groove 113 during the rotation of the turntable 112. The top of the turntable 112 is coaxially fixedly connected with a round rod 110, and the outer ring of the round rod 110 is provided with a first spiral groove 111; on the other hand, the outer ring of the housing 100 is slidably sleeved with a sleeve 115, and the inner wall of the top of the sleeve 115 is fixedly provided with a round tube 116 for the round rod 110 to extend into, and the inner ring of the round tube 116 is fixedly provided with a protrusion 117 with one end inserted into the first spiral groove 111. In addition, a return spring 118 is fixedly provided on the inner wall at the top of the sleeve 115 , and the bottom end of the return spring 118 is connected to a support ring 119 fixed to the inner wall of the housing 100 .

[0061] When the extrusion plate 121 needs to be closed, the sleeve 115 is pressed downward, and the sleeve 115 drives the round tube 116 and the protrusion 117 to move downward. The protrusion 117 moves downward and drives the round rod 110 to rotate through the first spiral groove 111. The rotation of the round rod 110 drives the guide groove 113 on the turntable 112 to rotate. The rotation of the guide groove 113 guides the driven block 123 to the end of the slide groove 124 close to the center of the first partition 101. At this time, the driven block 123 drives the extrusion plate 121 to move, thereby realizing the closing of multiple extrusion plates 121. When the extrusion plates 121 need to be dispersed, the sleeve 115 is released. At this time, the reset spring 118 rebounds and drives the sleeve 115, the round tube 116 and the protrusion 117 to move up and reset. The protrusion 117 drives the round rod 110 to rotate in the opposite direction through the first spiral groove 111. The round rod 110 drives the guide groove 113 on the turntable 112 to reverse, thereby guiding the driven block 123 to reset, so that the driven block 123 drives the extrusion plates 121 to reset, thereby achieving the dispersion of multiple extrusion plates 121.

[0062] In addition, Figure 4 In the embodiment, protrusions are provided at both ends of the top of the extrusion plate 121, and the protrusions extend into the grooves provided at the bottom of the first partition plate 101 (refer to Figure 5 The two sides of the middle slide groove 124 are used to limit the extrusion plate 121 to prevent the extrusion plate 121 from rotating.

[0063] Combination Figure 6 and Figure 7When the sampler of the present invention is used, the sampler is first placed above the food to be sampled, and then the sampler is moved downward to allow the food to enter the shaping area 102. Then, the driving mechanism drives the multiple extrusion plates 121 to move toward the center of the shaping area 102. At this time, the multiple extrusion plates 121 begin to close and squeeze the food in the shaping area 102 so that the outer surface of the food can fit with the side wall of the extrusion plate 121. In addition, during the closing process, the shaft rod 134 located on the side wall of the extrusion plate 121 will move with the extrusion plate 121. At this time, the friction between the shaft rod 134 and the slide groove 124 forces the shaft rod 134 to drive the driving wheel 133 to rotate, and the driving wheel 133 rotates to drive the sampling rod 131 to rotate, and the sampling rod 131 drives the sampling slot 132 to rotate. When the sampling slot 132 rotates to the shaping area 102, the food is squeezed into the sampling slot 132 because the food is in a squeezed state. Finally, the driving mechanism drives the multiple extrusion plates 121 to disperse. At this time, the extrusion plates 121 begin to reset, and the shaft 134 drives the sampling rod 131 to the reverse state through the driving wheel 133. When the extrusion plates 121 are reset, the sampling slots 132 rotate into the storage chamber 103 to achieve storage in the storage chamber 103.

[0064] That is to say, the food to be sampled is squeezed and shaped by the multiple squeezing plates 121 so that the food to be sampled can be tightly attached to the side wall of the squeezing plate 121, so that the food fills the sampling slot 132 under the action of squeezing, thereby achieving consistency in the sampling amount among the multiple sampling slots 132 and reducing the number of sampling times.

[0065] In order to increase the storage time of food in the storage cavity 103, as Figure 2 , Figure 3 and Figure 8 As shown, the end of the guide groove 113 near the outer ring of the rotating disk 112 is connected with an arc groove 114, and the center of the arc groove 114 is coaxial with the center of the rotating disk 112. A second partition 140 is fixedly arranged in the housing 100, the outer ring of which is fitted with the inner wall of the housing 100, and the inner ring is rotatably connected with the round rod 110, and the inner wall of the sleeve 115 is fitted with the outer ring of the housing 100, so that the space between the top of the second partition 140 and the sleeve 115 is sealed; in addition, a one-way air intake valve 141 is arranged in the second partition 140 for the gas at the bottom of the second partition 140 to enter the top of the second partition 140, and a one-way exhaust valve 142 is arranged on the side wall of the housing 100 above the second partition 140 for the gas inside the housing 100 to be discharged to the outside; the bottom of the housing 100 is detachably connected with a filter element 200.

[0066] First, place the bottom of the housing 100 on the top of the filter element 200. When the sleeve 115 moves down, the air between the sleeve 115 and the second partition 140 will be squeezed out through the one-way exhaust valve 142. When the sleeve 115 moves up and resets, the sleeve 115 will drive the multiple extrusion plates 121 to disperse, so that the bottom plate 122 moves to the bottom end of the housing 100, and the bottom of the storage chamber 103 is blocked; when the extrusion plates 121 are in a dispersed state, the driven block 123 is at the junction of the guide groove 113 and the arc groove 114; at this time, the sleeve 115 can continue to move up, and drive the arc groove 114 to rotate through the turntable 112, so that the driven block 123 enters the arc groove 114. Since the center of the arc groove 114 is coaxial with the center of the turntable 112, the arc groove 114 will not guide the driven block 123 to move, but will only make the sleeve 115 continue to move up. As the sleeve 115 continues to move upward, the cavity between the second partition 140 and the sleeve 115 is in a negative pressure state, so that the gas at the bottom of the second partition 140 is sucked in through the one-way air intake valve 141. At this time, the gas in the shaping area 102 and the storage chamber 103 is sucked into the cavity between the second partition 140 and the sleeve 115 through the connection between the slide groove 124 and the guide groove 113. The external gas enters the shaping area 102 and the storage chamber 103 after being filtered by the filter element 200, thereby reducing the number of bacteria in the storage chamber 103.

[0067] It can be seen that the driving mechanism can not only drive the extrusion plate 121 to close and disperse, but also can extract the air in the storage cavity 103 by adjusting the air pressure in the shell 100, and then cooperate with the filter element 200 to replace the gas in the storage cavity 103, thereby reducing the number of bacteria in the air in the storage cavity 103 and increasing the storage time of food in the storage cavity 103.

[0068] Moreover, in order to facilitate the removal of food in the sampling slot 132, Fig. 9 and Fig.10 As shown, the inner wall of the housing 100 is longitudinally slidably provided with a plurality of scrapers 150, and one end of the scraper 150 facing the sampling rod 131 is provided with a convex point. When the extrusion plate 121 is in a dispersed state, the convex point at the end of the scraper 150 is in the sampling groove 132. In addition, a convex rod 151 is provided at the other end of the scraper 150, and one end of the convex rod 151 passes through a slideway 152 opened on the side wall of the housing 100, and can slide longitudinally in the slideway 152.
