Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for precision laboratory instruments, and in particular to a dryer device. Background Technology

[0002] In laboratory settings such as chemical analysis, biopharmaceuticals, and materials science, desiccators are essential containers for storing reference materials, weighing bottles, and hygroscopic samples. However, existing ordinary glass or plastic desiccators have two significant drawbacks during use: First, the internal environment of the desiccator is extremely dry (very low humidity), and since weighing bottles are mostly made of glass, friction with the desiccator base during handling easily generates static electricity. The accumulation of static electricity not only attracts airborne dust particles that contaminate the samples, but also causes the charged weighing bottles to induce electrostatic induction with the balance coil when placed in an electronic balance, leading to drifting and instability in the weighing readings, severely affecting the accuracy of the balance. Second, weighing bottles often retain residual heat after being dried in an oven. While placing them directly into the desiccator isolates them from moisture, their natural cooling rate is slow. If weighing is performed before complete cooling, heat convection will interfere with the balance readings; furthermore, prolonged high-temperature environments may cause deterioration of some heat-sensitive samples. Existing solutions typically involve external ion fans (bulky and prone to dust generation) or simply laying aluminum foil (passive conductivity, inefficient, and unable to cool the sample).

[0003] In view of the above problems, there is an urgent need for a device with a simple structure, built into the dryer, and which has both active static electricity elimination and auxiliary cooling functions. Utility Model Content

[0004] In view of this, this application provides a dryer device. The main objective is to solve the technical problem that existing dryer devices cannot simultaneously achieve electrostatic discharge and active cooling within a confined space.

[0005] This utility model provides a dryer device that integrates static electricity elimination and constant temperature cooling functions. It mainly consists of two parts: a dryer body and a functional base assembly. The dryer body includes a dryer body and a functional base assembly located at the bottom of the dryer body. The functional base assembly includes a housing, a power supply unit disposed inside the housing, and a temperature-controlled support platform disposed at the top of the housing. The temperature-controlled support platform includes a thermoelectric cooling chip and a conductive support plate that are attached to each other. The conductive support plate is located at the top layer and is used to place the object to be dried. The power supply unit is electrically connected to the thermoelectric cooling chip and the conductive support plate via a control switch, forming a parallel power supply circuit.

[0006] Furthermore, the outer wall of the dryer body is provided with a mounting position for installing the control switch, and the control switch is connected to the functional base assembly through a wire passing through the dryer wall.

[0007] Furthermore, the shape of the conductive support plate is adapted to the inner diameter cross-sectional shape of the dryer body, and the lower surface of the conductive support plate is in contact with the cold end face of the semiconductor refrigeration chip to form a thermal conduction connection.

[0008] Furthermore, the functional base assembly also includes a heat dissipation structure, which is disposed on one side of the hot end face of the semiconductor cooling chip and located in the internal cavity of the housing.

[0009] Furthermore, the control switch is a waterproof push-button switch, which is fixed to the outer wall of the dryer body by a sealing gasket.

[0010] Furthermore, the power supply unit is a rechargeable lithium battery pack or a dry cell battery pack, and the housing is provided with a charging interface or battery compartment cover that is connected to the power supply unit.

[0011] Furthermore, the upper surface of the conductive carrier plate is provided with anti-slip texture or anti-slip protrusions, and the conductive carrier plate is connected to the negative terminal of the power supply unit or an independent electrostatic discharge circuit through a wire.

[0012] Furthermore, the dryer body has a receiving cavity at the bottom for embedding and installing the functional base assembly, and an insulating sealing cover plate is provided on the top of the receiving cavity, exposing only the working surface of the conductive support plate.

[0013] Furthermore, the conductive carrier plate has a groove or positioning mark in the central area to guide the weighing bottle to be placed accurately.

[0014] Furthermore, a thermally conductive silicone layer is added between the cold end face of the semiconductor cooling chip and the conductive carrier plate.

[0015] Beneficial effects: The dryer device provided by this utility model solves the two major problems of "static interference" and "heat residue" simultaneously with a single device. The conductive carrier plate actively guides the release of charge, and the semiconductor cooling chip quickly removes heat from the weighing bottle through heat conduction. In this application, the battery, cooling system, and conductive layer are integrated into a single base, which does not occupy additional effective storage space in the dryer and eliminates the need for an external power cord.

[0016] In addition, it is easy to operate. Users only need to press the external switch when picking up or placing samples to activate the protection mechanism, without the need for complicated equipment debugging.

[0025] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] Example 1 like Figure 1-3 As shown, in one feasible embodiment, the overall mechanical structure of the dryer device is described in detail: like Figure 1 As shown, the dryer device provided in this embodiment is an integrated device. It integrates two parts: a dryer body 1 and a functional base assembly 2. The dryer body 1 is a standard borosilicate glass dryer with a flat bottom. The functional base assembly 2 is located at the bottom of the dryer body 1. The functional base assembly 2 includes an insulating housing 21, which provides support and isolation. A power supply unit 22 and a temperature-controlled support platform located on top of the housing 21 are fixed within the internal cavity of the housing 21. The power supply unit 22 is a rechargeable lithium battery pack or a dry cell battery pack. The housing 21 has a charging interface or battery compartment cover connected to the power supply unit 22. In this embodiment, a 12V lithium battery pack is used and secured with clips.

[0027] In this embodiment, the dryer body 1 has a receiving cavity at the bottom for embedding and installing the functional base assembly 2, and the receiving cavity has an insulating sealing cover plate at the top, exposing only the working surface of the conductive support plate 24.

[0028] In this embodiment, the temperature-controlled support platform includes a thermoelectric cooler 23 and a conductive support plate 24 that are attached to each other. Specifically, the thermoelectric cooler 23 is embedded in the top opening of the housing 21. The cold end face of the cooling module faces upward, and the hot end face faces downward, pointing towards the inside of the housing. To prevent heat accumulation, the functional base assembly 2 also includes a heat dissipation structure. An aluminum alloy heat sink is provided below the hot end face of the thermoelectric cooler 23 as a heat dissipation structure. The uppermost layer is covered by the conductive support plate 24 for placing the object to be dried.

[0029] In one feasible implementation, 1. S (Shape): The conductive support plate 24 is a circular thin sheet with a diameter of 180mm, and its shape is adapted to the inner diameter cross-sectional shape of the dryer body 1. It is in slight motion fit with the inner wall of the dryer body 1, and the lower surface of the conductive support plate 24 is attached to the cold end face of the semiconductor cooling chip 23 to form a thermal conduction connection.

[0030] In this embodiment, the upper surface of the conductive support plate 24 is provided with anti-slip texture or anti-slip protrusions, and the conductive support plate 24 is connected to the negative terminal of the power supply unit 22 or an independent electrostatic discharge circuit through a wire. The central area of ​​the conductive support plate 24 is provided with a groove or positioning mark to guide the weighing bottle to be placed accurately. II. M (Material): The conductive support plate 24 is made of conductive silicone sheet, which has good flexibility and thermal conductivity. The flexible material ensures a tight fit when the weighing bottle is placed down, increasing the thermal and electrical conductivity area. In another feasible embodiment, a thermally conductive silicone layer is added between the cold end face of the semiconductor refrigeration chip 23 and the conductive support plate 24 to increase the thermal and electrical conductivity area. III. C (Connection): The lower surface of the conductive support plate 24 is directly attached to the cold end face of the semiconductor refrigeration chip 23.

[0031] In one feasible implementation, the power supply unit 22 is electrically connected to the semiconductor cooling chip 23 and the conductive carrier plate 24 respectively through the control switch 25 to form a parallel power supply circuit. The outer wall of the dryer body 1 is provided with a mounting position for installing the control switch 25. The control switch 25 is connected to the functional base assembly 2 through a wire passing through the dryer wall.

[0032] In this embodiment, the control switch 25 is a waterproof push-button switch, which is fixed to the outer wall of the dryer body 1 by a sealing gasket.

[0033] Example 2: As a further refinement of Embodiment 1, the circuit and working principle of the dryer device are as follows: In this embodiment, the control switch 25 is installed below the cover handle or on the side flange of the dryer body 1, and an IP65 waterproof button is selected.

[0034] In one feasible implementation, the circuit connection logic of the dryer device is as follows: Static electricity elimination circuit: The conductive support plate 24 is connected to the common ground terminal (GND) of the circuit via a wire or to the negative terminal via a current-limiting resistor. When a weighing bottle carrying static electricity is placed on the conductive support plate 24, the charge is rapidly conducted to the low potential end through the large-area contact conductive layer, thereby neutralizing the static electricity.

[0035] Cooling circuit: Pressing the control switch 25, the power supply unit 22 supplies power to the thermoelectric cooler 23. Utilizing the Peltier effect, the upper cold end of the thermoelectric cooler 23 cools down rapidly, absorbing heat from the weighing bottle above the thermoelectric cooler 23 through the conductive support plate 24 (which also has a thermal conductivity function); the heat generated at the lower hot end of the thermoelectric cooler 23 is buffered in the space at the bottom of the base through the heat dissipation structure or absorbed by the phase change material (Note: A micro fan can be added during application, but in practice, heat absorption using heat capacity is sufficient to meet short-term cooling requirements).

[0036] In one feasible implementation, the working process of the device of this utility model is as follows: The experimenter puts the dried weighing bottle into the desiccant device, specifically on the conductive support plate 24, and then presses the control switch 25. At this time, the desiccant device is started, the conductive support plate 24 instantly releases static electricity, and at the same time the semiconductor cooling chip 23 starts to work, accelerating the cooling of the weighing bottle to room temperature. Then, after 5-10 minutes, the bottle is taken out for weighing, and the data is stable and accurate.

[0037] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
