Description

Technical Field

[0001] This utility model relates to the field of food heavy metal detection technology, specifically a food heavy metal content analysis device. Background Technology

[0002] Food heavy metal content analysis equipment is a specialized instrument used to detect harmful heavy metal elements (such as lead, cadmium, mercury, arsenic, etc.) in food. It employs advanced analytical techniques, such as atomic absorption spectrometry (AAS) and inductively coupled plasma mass spectrometry (ICP-MS), to rapidly and accurately determine the trace heavy metal content in food, ensuring food safety and compliance with relevant national standards.

[0003] Existing portable food heavy metal content analysis devices typically place the detector inside the housing. After the sample is placed in the detector for testing, the data is displayed on the screen. For example, the portable food heavy metal detector BZ01 from Lained Intelligent Technology has a display screen embedded on top of the detector inside the housing to display the test data. However, the display screen is vertically upward, which makes it difficult for the user to observe the data when the data is displayed on the screen and the user is far away from the detector. This makes the use of the detector inconvenient. Therefore, we propose a food heavy metal content analysis device. Utility Model Content

[0004] The purpose of this invention is to provide a food heavy metal content analysis device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a food heavy metal content analysis device, including a housing, a detector is provided inside the housing, a mounting groove is provided on the top of the detector, a display screen is provided inside the mounting groove, support components are provided on both sides of the display screen, a water-absorbing component is provided on the side wall of the mounting groove, and the support components can provide tilt support for the display screen.

[0006] Preferably, the support assembly includes a fixed column fixed to the side wall of the display screen, a rotating rod rotatably connected to the side wall of the fixed column, a slider rotatably connected to the side wall of the rotating rod, and a limiting block fixed to the side wall of the slider.

[0007] Preferably, the top of the mounting groove is provided with a sliding groove that matches the slider, and the top of the slider is provided with a locking knob.

[0008] Preferably, the water-absorbing assembly includes a water-absorbing element fixed to the side wall of the mounting groove, a sponge block disposed inside the water-absorbing element, a locking element disposed on the top of the water-absorbing element, and a connecting port machined on the side wall of the water-absorbing element.

[0009] Preferably, the mounting groove is provided with a slanted panel, which fits into the bottom of the display screen.

[0010] Preferably, the display screen is fixed to two ends with rotating shafts, and the rotating shafts are fitted into the inner wall of the mounting groove.

[0011] Preferably, the top of the box is provided with a box cover, and a sponge pad is provided inside the box cover.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention features a mounting groove and an internal rotatable display screen on the detector. During use, loosening the locking knob allows the slider to be pushed forward along the sliding groove, causing the front end of the rotating rod to rotate upwards, thus rotating the display screen along the rotating shaft. The rear end of the display screen rotates upwards, tilting it. Tightening the locking knob locks the slider, fixing the tilt angle of the display screen. This allows the display screen to be rotated upwards from the top of the detector. This facilitates observation of data displayed on the food heavy metal content analysis equipment, avoiding the situation where the display screen is vertically upwards, making it difficult for users at a distance to see the data. This significantly improves the convenience of using the food heavy metal content analysis equipment.

[0014] When the detection liquid spills onto the top surface of the detector and flows into the mounting tank during use, the liquid is guided to the right by the inclined panel and enters the interior of the absorbent component through the connecting port. At this time, the sponge block inside the absorbent component can absorb the liquid, thereby allowing the liquid inside the mounting tank to be concentrated and absorbed, avoiding the trouble of liquid accumulation inside the mounting tank and making it inconvenient to clean. At the same time, it can also prevent the liquid from accumulating inside the mounting tank and wetting the display screen. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0022] Please see Figures 1-5 The illustrated food heavy metal content analysis device includes a housing 100, inside which is a detector 110. The electrical components inside the housing 100 and the detector 110 use a portable food heavy metal detector, model BZ01, from the brand R&D Intelligent Technology, which is existing technology and will not be described in detail here. The top of the detector 110 is provided with a mounting slot 120, inside which is a display screen 111. Support components are provided on both sides of the display screen 111, and a water-absorbing component is provided on the side wall of the mounting slot 120. The support components can provide tilt support for the display screen 111. The display screen 111 uses a common LCD screen, which consists of a waterproof plastic shell, a display chip, and a touch screen component. The display chip is electrically connected to the electrical components inside the detector 110 and can display the processed data on the display screen 111, which is existing technology. The side wall of the mounting slot 120 has a circular hole for wiring of the display screen 111.

[0023] Specifically, the support assembly includes a fixed post 140 bolted to the side wall of the display screen 111, a rotating rod 141 rotatably connected to the side wall of the fixed post 140, a slider 142 rotatably connected to the side wall of the rotating rod 141, and a limiting block 143 glued to the side wall of the slider 142. The limiting block 143 can limit the sliding of the slider 142.

[0024] Furthermore, the top of the mounting groove 120 is provided with a sliding groove 145 that matches the slider 142. The top of the slider 142 is provided with a locking knob 144. The locking knob 144 is a common bolt that can be turned by hand. When the locking knob 144 is tightened, it can press against the top of the mounting groove 120 to lock the slider 142.

[0025] Furthermore, the water-absorbing assembly includes a water-absorbing component 130 glued and fixed to the side wall of the mounting groove 120, a sponge block 131 disposed inside the water-absorbing component 130, a locking component 132 disposed on the top of the water-absorbing component 130, and a connecting port 133 machined on the side wall of the water-absorbing component 130. The top of the water-absorbing component 130 can be opened by rotating the locking component 132 so that the sponge block 131 can be replaced. The connecting port 133 can connect the internal cavity of the mounting groove 120 and the water-absorbing component 130. At the same time, the bottom of the internal cavity of the water-absorbing component 130 is lower than the internal cavity of the mounting groove 120.

[0026] In some embodiments, the top of the detector 110 may be sloped, such that the mounting groove 120 is the lower part of the top surface of the detector 110, so that liquid falling onto the top of the detector 110 can flow into the interior of the mounting groove 120 and be absorbed by the absorbent 130.

[0027] Furthermore, the mounting slot 120 is equipped with a slanted panel 113, which fits into the bottom of the display screen 111. The slanted panel 113 is set with the left side higher than the right side.

[0028] It is worth noting that the display screen 111 has a rotating shaft 112 glued to both ends. The rotating shaft 112 fits into the inner wall of the mounting groove 120, and the inner wall of the mounting groove 120 has a round hole groove that fits into the rotating shaft 112.

[0029] It is worth noting that a lid 101 is provided on the top of the box 100, and a sponge pad is provided inside the lid 101.

[0030] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0031] Working principle: The detector 110 has a mounting slot 120 and an internal rotatable display screen 111. When using the detector 110, loosening the locking knob 144 allows the slider 142 to be pushed forward along the sliding groove 145, causing the front end of the rotating rod 141 to rotate upwards. This rotates the display screen 111, which is then engaged with the rotating shaft 112. At this point, the rear end of the display screen 111 rotates upwards, tilting it. Tightening the locking knob 144 locks the slider 142, thus fixing the tilt angle of the display screen 111. This allows the display screen 111 to rotate upwards from the top of the detector 110, facilitating observation of data displayed on the screen 111 of the food heavy metal content analysis equipment and preventing data loss. 1. The vertically upward orientation of the device, located in front of the analyzer, makes it difficult for users to observe the data from a distance, thus improving the convenience of using the food heavy metal content analyzer. 2. When the test liquid spills onto the top surface of the detector 110 and flows into the installation tank 120, it is guided to the right by the inclined panel 113 and enters the absorbent component 130 through the connecting port 133. At this time, the sponge block 131 inside the absorbent component 130 can absorb the liquid, thus concentrating the liquid inside the installation tank 120 and avoiding the trouble of cleaning the liquid accumulation inside the installation tank 120. At the same time, it can also prevent the liquid from accumulating inside the installation tank 120 and wetting the display screen 111.
