Description

Technical Field

[0001] The utility model relates to the technical field of food detection, in particular to a water bath device used for food detection. Background Art

[0002] Water baths are mainly used in laboratories for distillation, drying, concentration, and soaking of chemicals or biological products. They can also be used for constant temperature heating and other temperature tests. Water baths are also widely used in the field of food testing. By injecting water for heating into the water bath, the material to be tested is placed on the upper part of the water bath tank, and the water source is heated by the heating element inside the water bath, so that the heated water source heats the food material to be tested, so that researchers can observe and study the detection of food materials at different temperatures.

[0003] Chinese patent CN202121326603.2 discloses a constant temperature water bath for food inspection, which includes a constant temperature water bath body. The constant temperature water bath body is provided with a combined cover plate, the innermost periphery of the combined cover plate is the innermost cover ring, and the lower part of the innermost cover ring is rotatably provided with two symmetrical clamping arms on the inner peripheral surface. The movable ends of the two clamping arms can rotate toward the center of the innermost cover ring, and a positioning area for clamping a test tube is formed between the two clamping arms; a fan is also provided on the upper part of the constant temperature water bath body, and the fan is used to blow dry the water stains inside the constant temperature water bath body when the constant temperature water bath body is not in use.

[0004] In the above technical solution, no water flow control structure is provided inside the water bath. Therefore, during the constant temperature heating process of the water body, there is still a certain temperature difference, that is, the temperature of the area closer to the heating element is higher, and the water temperature control of each area in the water body relies solely on the heat conduction of the water molecules themselves and the local surge during boiling, which is inefficient and poorly controllable. In particular, due to the different placement positions of samples in the same batch, there are errors in the water bath effect, which will affect the subsequent test results. Utility Model Content

[0027] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model for which protection is claimed, but merely represents selected embodiments of the present invention.

[0028] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically specified.

[0029] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1: Combination Figure 1 and Figure 2 This embodiment discloses a water bath device for food testing, including a shell 1, a container 2, an inner cavity 3, a heating element 4, a vortex generator 5 and a human-computer interaction module 11.

[0032] The housing 1 is a rectangular box structure made of aluminum alloy, and mainly plays a bearing and supporting role.

[0033] The front of the housing 1 is provided with a human-machine interaction module 11, which includes a display screen, buttons, and a control chip. The control chip is located within the housing 1. The physical structure of the control chip is specifically a circuit board. The functional modules are designed and selected based on actual needs. This is prior art, and its specific structure and operating principle will not be described in detail here. Those skilled in the art can select and implement existing technologies based on actual operating conditions. The display screen and buttons are located on the front of the housing 1. The display screen is used to display the operating parameters and operating status of the device, and the buttons are used to facilitate user control of the device, including but not limited to parameter setting and on / off control.

[0034] Furthermore, a storage slot 12 with a square sink structure is provided on the top of the shell 1, and four card slots 13 are provided in the storage slot 12. A container 2 for holding the sample is inserted in the card slot 13. The bottom of the container 2 is a test tube structure, and the top is provided with a cover body that can form a card-connecting structure with the card slot 13. In this embodiment, the bottom of the container 2 is made of glass material. The interior is used to hold the sample to be water bathed. The top of the container 2 is made of plastic. The cover body can be firmly clamped on the top opening of the test tube. It should be noted that after installation, the bottom of the container 2 is in the inner cavity 3, and the top extends into the storage slot 12. A pulling hole 21 is provided on the cover body, which is convenient for users to use tools to penetrate and hook to prevent accidental burns.

[0035] Specifically, the slot 13 is a T-shaped through-hole structure, and the container 2 is a cross-shaped structure. The housing 1 on top of the container 2 can form a one-way limited engagement structure with the slot 13. To ensure more stable placement of the container 2 and better sealing of the inner cavity 3 during operation, an elastic gasket is sleeved on the inner side of the slot 13.

[0036] like Figure 2 As shown, the shell 1 is provided with an inner cavity 3 for accommodating water, and the inner cavity 3 is located directly below the storage groove 12. The card slot 13 connects the storage groove 12 and the inner cavity 3. The inner cavity 3 in this embodiment is made of a square inner tank, and its rear end is provided with a water inlet and outlet pipe with an electromagnetic valve opening and closing control. The shell 1 is provided with an installation cavity on one side of the inner cavity 3, and a control module 6 is provided inside. The control module 6 specifically includes a water pump, a battery, and an electronic control component. Its function is to serve as a supporting component of the water inlet and outlet and temperature control system. It is a prior art, and its specific structure and working principle are not repeated here. Those skilled in the art can select and implement it from the prior art according to actual operating conditions.

[0037] Furthermore, heating elements 4 are evenly distributed on the bottom and sides of the inner cavity 3. The heating elements 4 are electric heating wires that can heat the water in the inner cavity 3 at intervals. The three-sided evenly distributed heating wires ensure that when heating, the water in each area of ​​the inner cavity 3 can timely obtain temperature changes, thereby reducing temperature differences.

[0038] Vortex finders 5 are located at the bottom of the inner chamber 3, corresponding to each container 2. These vortex finders 5 continuously swirl the water at the bottom of the container 2 upward, enveloping it. These vortex finders act as active control structures, increasing the fluidity of the water inside and ensuring water circulation around the container 2, reducing temperature fluctuations and accelerating heat transfer.

[0039] Of course, a temperature control module is provided in the inner cavity 3 to monitor the internal water temperature in real time. This is an existing technology, and its specific structure and working principle will not be described here. Those skilled in the art can select and implement it from the existing technology according to actual operating conditions.

[0040] In order to improve the heating and heat preservation efficiency and reduce heat loss, the outer periphery of the inner cavity 3 is wrapped with a heat preservation structure, specifically heat preservation cotton (not shown in the figure).

[0041] In order to facilitate cleaning and maintenance, the vortex finder 5 is detachably connected to the bottom of the inner cavity 3, specifically using a snap-fit ​​structure.

[0042] Example 2: Based on Example 1, Figure 3-5 As shown, in this embodiment, a heat-conducting cover 7 made of a heat-conducting material (stainless steel in this embodiment, but ceramic or other materials may also be used in other embodiments) is provided on top of the vortex finder 5. The heat-conducting cover 7 can wrap around the portion of the container 2 located in the inner cavity 3. The function of the heat-conducting cover 7 is to provide a partition structure around each container 2. This not only cooperates with the vortex finder 5 to significantly shorten the water volume and circulation path, increasing the number of cycles to improve heat conduction uniformity, but also uses the heat conduction effect of its own structure to provide a stable and reliable constant temperature framework structure for the container 2.

[0043] Furthermore, water holes 71 are provided at the upper and lower ends of the heat-conducting cover 7 , and the water holes 71 radially penetrate the side wall of the heat-conducting cover 7 , thereby ensuring effective interaction between the water inside and outside the heat-conducting cover 7 .

[0044] Furthermore, in order to improve the circulation efficiency and eddy current stability of the water inside the heat-conducting cover 7, Figure 5 As shown, Figure 5 The heat-conducting cover 7 in the figure only shows the middle area, and the water-permeable holes 71 on the upper and lower sides are not shown. The inner wall of the heat-conducting cover 7 is provided with a spiral guide blade 72. The guide blade 72 can guide the upwelling water flow and has a certain confluence effect, further improving the heat conduction effect and reducing the temperature difference change.

[0045] In other embodiments, the heat-conducting cover 7 may further be provided with a concave-convex pleated structure on the side wall to increase the direct contact area with the water body and improve the heat conduction effect.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
