Description

Technical Field

[0001] This utility model belongs to the technical field of water activity meters, and more specifically, it relates to a water activity meter with controllable temperature. Background Technology

[0002] A water activity meter is an instrument used to determine the water activity in a sample. Its core function is to assess the sample's stability, microbial growth risk, and shelf life by measuring the energy state of water in the sample (i.e., the ratio of free water to bound water). This instrument is widely used in the food, pharmaceutical, and cosmetic industries for quality control, packaging material evaluation, and formulation optimization.

[0003] In existing water activity meter designs, some devices use external sensors, which require wire harness plug-in to achieve signal transmission. The sensor interface adopts a simple direct plug design, and its plug is fixed by friction alone. It is prone to loosening when frequently plugged and unplugged or when the equipment vibrates, resulting in signal interruption or data distortion. Utility Model Content

[0004] To address the problem that the sensor interface uses a simple plug-in design, where the plug is fixed only by friction, it is prone to loosening during frequent plugging and unplugging or equipment vibration, leading to signal interruption or data distortion, this utility model proposes a temperature-controlled water activity meter to overcome the aforementioned technical problems existing in related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a temperature-controlled water activity meter, comprising a base, a main unit fixedly connected to the top of the base, a storage component inside the base, a limiting component and a pop-out component respectively provided between the storage component and the base, a temperature control seat inside the storage component, a sample dish placed inside the temperature control seat, a sensor on the top of the sample dish, a wire harness inserted into the outer surface of the sensor, and a connecting component between the sensor and the wire harness. The storage component is used to store the sample dish into the base, the limiting component is used to limit and fix the storage component, the pop-out component is used to assist the storage component to slide out of the base, and the connecting component is used to strengthen the connection between the sensor and the wire harness.

[0007] Furthermore, the storage component includes a storage box, which is slidably connected to the inside of the base. The inside of the base is provided with a storage groove and a sliding groove. A sliding plate is slidably connected inside the sliding groove. The sliding plate is fixedly connected to the bottom of the storage box. The temperature control seat is fixedly installed inside the storage box.

[0008] Furthermore, the limiting component includes a limiting handle, a limiting plate is fixedly connected to the outer surface of the limiting handle, a first spring is fixedly connected to the outer surface of the limiting plate, the upper end of the first spring is fixedly connected to the inside of the storage box, the limiting handle and the limiting plate are slidably connected inside the storage box, and the limiting handle is inserted into the base.

[0009] Furthermore, the pop-out assembly includes a fixing rod, which is fixedly connected inside the slide groove. The fixing rod has a stepped hole inside, and a circular plate and a sliding rod are slidably connected inside the stepped hole. One side of the circular plate is fixedly connected to the sliding rod, and the other side of the circular plate is fixedly connected to a second spring. One end of the second spring is fixedly connected inside the stepped hole, and one end of the sliding rod is fixedly connected to the sliding plate.

[0010] Furthermore, the connecting assembly includes a solenoid sleeve fitted onto the outer surface of the wiring harness, and a connecting seat threaded onto the outer surface of the solenoid sleeve, the connecting seat being fixedly connected inside the sensor.

[0011] Furthermore, the bottom of the base is fixedly connected with an anti-slip pad.

[0012] Furthermore, a knob is rotatably connected to the outer surface of the host.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model connects the wire harness and the connecting component. The connecting component is divided into two parts and is located between the wire harness and the sensor. After connecting the two parts of the connecting component, the resistance when separating the connecting component is greater than the friction between the wire harness and the sensor. The connecting component limits the wire harness and fixes it inside the sensor. At this time, the connecting component can strengthen the connection between the wire harness and the sensor and avoid the situation where loosening will affect the data transmission.

[0015] 2. This utility model connects the storage box and the sliding rod. The storage box can carry the sensor into the base for storage and protection. When the storage box is in the base, the sliding plate at the bottom of the storage box pushes the sliding rod to compress the second spring. After releasing the limiting and fixing of the storage box, the second spring pushes the sliding rod and the sliding plate, so that the sliding plate drives the storage box to slide out of the base, which is more convenient to use.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-7 As shown, this utility model is a temperature-controlled water activity meter, including a base 1, a main unit 2 fixedly connected to the top of the base 1, a storage component 3 inside the base 1, a limiting component 4 and a pop-out component 5 respectively provided between the storage component 3 and the base 1, a temperature control seat 6 inside the storage component 3, a sample dish 7 placed inside the temperature control seat 6, a sensor 8 on the top of the sample dish 7, a wire harness 9 inserted into the outer surface of the sensor 8, and a connecting component 10 between the sensor 8 and the wire harness 9. The storage component 3 is used to store the sample dish 7 into the interior of the base 1, the limiting component 4 is used to limit and fix the storage component 3, the pop-out component 5 is used to assist the storage component 3 to slide out of the base 1, and the connecting component 10 is used to strengthen the connection between the sensor 8 and the wire harness 9.

[0030] Pull the limiting component 4 to slide, so that the limiting component 4 separates from the base 1, and releases the limiting fixation between the storage component 3 and the base 1. At this time, the pop-out component 5 can push the storage component 3 out of the base 1. After the sample to be tested is placed into the sample dish 7, the sensor 8 is attached. The temperature of the sample in the sample dish 7 can be adjusted by the temperature control seat 6. The sensor 8 feeds back the detected data to the host 2. The connecting component 10 firmly fixes the wire harness 9 to the sensor 8, which can ensure the stability of the data transmission of the sensor 8.

[0031] This utility model connects the wire harness 9 and the connecting component 10. The connecting component 10 is divided into two parts and is located between the wire harness 9 and the sensor 8. After connecting the two parts of the connecting component 10, the resistance when separating the connecting component 10 is greater than the friction between the wire harness 9 and the sensor 8. The connecting component 10 limits the wire harness 9 and fixes it inside the sensor 8. At this time, the connecting component 10 can strengthen the connection between the wire harness 9 and the sensor 8 and avoid the situation where loosening will affect the data transmission.

[0032] In one embodiment, the storage component 3 includes a storage box 301, which is slidably connected to the inside of the base 1. The inside of the base 1 is provided with a storage groove 302 and a sliding groove 303. A sliding plate 304 is slidably connected inside the sliding groove 303. The sliding plate 304 is fixedly connected to the bottom of the storage box 301. The temperature control seat 6 is fixedly installed inside the storage box 301.

[0033] Pulling the storage box 301 causes it to slide out of the storage slot 302 within the base 1, exposing the sensor 8 and sample dish 7 inside. The storage box 301 then moves the sliding plate 304 within the sliding groove 303, which limits the movement distance of the sliding plate 304 and the storage box 301, preventing the storage box 301 from detaching from the base 1. After removing the sensor 8 from above the sample dish 7, the sample can be placed inside. The sensor is then reattached to the top of the sample dish 7, and the temperature control base 6 at the bottom of the sample dish 7 is activated to adjust the temperature. The sensor 8 detects the sample inside the sample dish 7 at the appropriate temperature, and transmits the data to the host 2 via the wiring harness 9.

[0034] In one embodiment, the limiting component 4 includes a limiting handle 401, a limiting plate 402 fixedly connected to the outer surface of the limiting handle 401, a first spring 403 fixedly connected to the outer surface of the limiting plate 402, the upper end of the first spring 403 fixedly connected to the inside of the storage box 301, the limiting handle 401 and the limiting plate 402 slidably connected inside the storage box 301, and the limiting handle 401 is inserted into the base 1.

[0035] Pull the limit handle 401 downwards, and the limit handle 401 will cause the limit plate 402 to slide downwards. The limit plate 402 will compress the first spring 403, and the limit handle 401 will separate from the base 1, releasing the limit fixation between the base 1 and the storage box 301. Then the storage box 301 can be pulled out from the base 1.

[0036] In one embodiment, the pop-out component 5 includes a fixing rod 501, which is fixedly connected to the inside of the slide groove 303. A stepped hole 502 is provided inside the fixing rod 501. A circular plate 503 and a sliding rod 504 are slidably connected inside the stepped hole 502. One side of the circular plate 503 is fixedly connected to the sliding rod 504, and a second spring 505 is fixedly connected to the other side of the circular plate 503. One end of the second spring 505 is fixedly connected to the inside of the stepped hole 502, and one end of the sliding rod 504 is fixedly connected to the sliding plate 304.

[0037] When the storage box 301 is located in the storage slot 302, the sliding plate 304 at the bottom of the storage box 301 pushes the sliding rod 504 and the round plate 503 to compress the second spring 505. After the limiting fixation of the storage box 301 is released, the second spring 505 pushes the round plate 503 and the sliding rod 504 to slide in the stepped hole 502 on the fixed rod 501, so that the sliding rod 504 pushes the sliding plate 304 to move the storage box 301, thereby popping out the storage box 301.

[0038] In one embodiment, the connection component 10 includes a solenoid 1001, which is sleeved on the outer surface of the wire harness 9. A connector 1002 is threaded onto the outer surface of the solenoid 1001, and the connector 1002 is fixedly connected to the inside of the sensor 8.

[0039] When the solenoid 1001 is sleeved on the outer surface of the wire harness 9, the solenoid 1001 can slide and rotate on the outer surface of the wire harness 9. After the wire harness 9 is inserted into the sensor 8, the solenoid 1001 is pushed close to the connector 1002 and rotated to make it threadedly connected to the connector 1002. At this time, the solenoid 1001 can limit and fix the wire harness 9 to prevent the wire harness 9 from becoming loose with the sensor 8.

[0040] In one embodiment, for the base 1, an anti-slip pad 11 is fixedly connected to the bottom of the base 1.

[0041] There are multiple sets of anti-slip pads 11, which are symmetrically arranged at the bottom of the base 1. The multiple sets of anti-slip pads 11 support the base 1, leaving a certain gap between the base 1 and the tabletop, making it easy to move the base 1.

[0042] In one embodiment, for the host 2 described above, a knob 12 is rotatably connected to the outer surface of the host 2.

[0043] The knob 12 is electrically connected to the temperature control base 6. The temperature control base 6 can be heated by a resistance wire. Rotating the knob 12 changes the resistance value of the temperature control base 6, thereby changing the temperature.

[0044] Through the above technical solution, 1. By connecting the wire harness 9 and the connecting component 10, the connecting component 10 is divided into two parts. The connecting component 10 is located between the wire harness 9 and the sensor 8. After connecting the two parts of the connecting component 10, the resistance when separating the connecting component 10 is greater than the frictional force between the wire harness 9 and the sensor 8. Furthermore, the connecting component 10 limits and fixes the wire harness 9 within the sensor 8. At this time, the connecting component 10 can strengthen the connection between the wire harness 9 and the sensor 8, preventing loosening that could affect data transmission. 1. The situation occurs; 2. Through the connection between the storage box 301 and the sliding rod 504, the storage box 301 can bring the sensor 8 into the base 1 for storage and protection. When the storage box 301 is located in the base 1, the sliding plate 304 at the bottom of the storage box 301 pushes the sliding rod 504 to compress the second spring 505. After releasing the limiting fixation of the storage box 301, the second spring 505 pushes the sliding rod 504 and the sliding plate 304, so that the sliding plate 304 drives the storage box 301 to slide out of the base 1, which is more convenient to use.
