Abstract

This utility model relates to the field of water bath devices, and discloses a multi-chamber water bath device for the verification of chemical measuring instruments. It includes a water bath tank, a light-transmitting plate fixedly connected to the front surface of the water bath tank, a chamber division device at the upper end of the water bath tank, and an automatic water replenishment device at the back of the water bath tank. The automatic water replenishment device includes a water storage tank, a connecting pipe fixedly connected to the lower end of the outer arc surface of the water storage tank, and a baffle connected to the lower end of the inner surface of the connecting pipe. In this utility model, through the configured water storage tank, connecting pipe, linkage plate, baffle, connecting rod, and float, as the water stored inside the water bath tank gradually heats up and evaporates, the up-and-down movement of the float inside the water bath tank drives the baffle to move inside the connecting pipe. The movement of the baffle controls the opening or closing state of the connecting pipe, thereby automatically replenishing the water stored in the water storage tank to the corresponding chambers inside the water bath tank.

Description

Technical Field

[0001] This utility model relates to the field of water bath devices, and in particular to a multi-chamber water bath device for the calibration of chemical measuring instruments. Background Technology

[0002] A water bath is a piece of equipment used in laboratories to immerse samples or reagents in water at a constant temperature. This device typically consists of a heating element, a temperature control system, and a water bath. Its main function is to maintain samples or reagents at specific temperature conditions during experiments to facilitate reactions, dissolutions, or other temperature-controlled operations. In the prior art, water bath devices require placing chemical measuring instruments waiting to be treated in the water bath tank and maintaining the gradual and uniform temperature rise of the chemical measuring instruments by heating.

[0003] However, in actual use, as the water gradually evaporates during the heating process inside the water bath, the liquid level inside the water bath will change accordingly. At this time, some of the taller chemical measuring instruments will be exposed above the water surface, thus preventing the chemical measuring instruments from being fully heated by the water bath. To address this problem, a multi-chamber water bath device for the calibration of chemical measuring instruments is proposed. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a multi-chamber water bath device for the calibration of chemical measuring instruments, which aims to improve the problem in the prior art where the natural evaporation of water during the water bath process will reduce the liquid level and thus affect the water bath effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-chamber water bath device for the verification of chemical measuring instruments, comprising a water bath tank, a light-transmitting plate fixedly connected to the front surface of the water bath tank, a chamber division device provided at the upper end of the water bath tank, and an automatic water replenishment device provided at the back of the water bath tank. The automatic water replenishment device includes a water storage tank. A connecting pipe is fixedly connected to the lower end of the outer arc surface of the water storage tank. A baffle is piston-connected to the lower end of the inner surface of the connecting pipe. A linkage plate is fixedly connected to the lower end of the baffle. A connecting rod is fixedly connected to the upper end of the linkage plate. A float plate is fixedly connected to the end of the connecting rod away from the linkage plate.

[0006] As a further description of the above technical solution: The chamber partitioning device includes a partition plate, a magnetic plate is fixedly connected to the upper end of the partition plate, a cover plate is slidably connected to the outer surface of the partition plate, a fixed shaft is fixedly connected to the lower end of the cover plate, an outer shaft is rotatably connected to the outer arc surface of the fixed shaft, and a shielding plate is fixedly connected to the lower end of the outer arc surface of the outer shaft.

[0007] As a further description of the above technical solution: The water bath tank has multiple through holes on its front surface and multiple through holes on its back surface. The water storage tank has a water inlet at its upper end.

[0008] As a further description of the above technical solution: The lower end of the outer arc surface of the water storage tank has a through hole, the lower end of the connecting pipe has a rectangular groove, the upper end of the baffle has two sets of rectangular protrusions, and the upper end of the inner surface of the connecting pipe has a rectangular groove.

[0009] As a further description of the above technical solution: The connecting rods are provided in two sets, and the two sets of connecting rods are stacked and distributed with the center line of the linkage plate as the axis of symmetry. The connecting rods are generally set in an L-shape, and the outer surface of the float plate is slidably connected to the water bath tank.

[0010] As a further description of the above technical solution: The partition plate is provided in multiple sets, and the spacing between the multiple sets of partition plates is equal. The partition plate is connected to the piston of the water bath tank.

[0011] As a further description of the above technical solution: The inner surface of the cover plate has multiple through holes, the lower surface of the cover plate has an arc-shaped groove, and the lower surface of the cover plate has multiple rectangular grooves.

[0012] As a further description of the above technical solution: The outer arc surface of the fixed shaft is elastically connected to the outer shaft by a spiral spring. A through hole is opened at the center of the inner surface of the outer shaft. The length of the baffle plate is the same as the width of the rectangular groove at the lower end of the cover plate.

[0013] This utility model has the following beneficial effects: 1. In this utility model, the water storage tank, connecting pipe, linkage plate, baffle, connecting rod, and float plate are configured so that as the water stored inside the water bath gradually heats up and evaporates, the float plate moves up and down inside the water bath, thereby driving the baffle to move inside the connecting pipe. The movement of the baffle plate controls the opening or closing state of the connecting pipe, thereby automatically replenishing the water stored inside the water storage tank to the corresponding compartment inside the water bath.

[0014] 2. In this utility model, the magnetic plate, shielding plate, partition plate, cover plate, fixed shaft, and outer shaft are configured to fix the position of the partition plate when it is inserted into the water bath by the attraction between the cover plate and the magnetic plate. At the same time, when the partition plate is removed to adjust the compartment, the shielding plate will be automatically rotated by the elastic force of the spiral spring and will block the through hole after the partition plate is pulled out, thereby reducing the evaporation of water inside the water bath and dividing the water bath into chambers.

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.

[0018] Reference Figures 1-3An embodiment of this utility model is provided: a multi-chamber water bath device for the verification of chemical measuring instruments, including a water bath 1. The lower end of the inner surface of the water bath 1 is provided with multiple sets of heating devices, so that the water stored inside the water bath 1 can be heated during the water bath process. A light-transmitting plate 4 is fixedly connected to the front surface of the water bath 1. A chamber dividing device 3 is provided at the upper end of the water bath 1. An automatic water replenishment device 2 is provided at the back of the water bath 1. The automatic water replenishment device 2 includes a water storage tank 201. A connecting pipe 202 is fixedly connected to the lower end of the outer arc surface of the water storage tank 201. A baffle 204 is piston-connected to the lower end of the inner surface of the connecting pipe 202. A linkage plate 203 is fixedly connected to the lower end of the baffle 204. A connecting rod 205 is fixedly connected to the upper end of the linkage plate 203. A float plate 206 is fixedly connected to the end of the connecting rod 205 away from the linkage plate 203.

[0019] Multiple through holes are formed on the front surface of the water bath 1 to accommodate the light-transmitting plate 4. Multiple through holes are also formed on the back of the water bath 1 to connect it to the connecting pipe 202. A water inlet is provided at the upper end of the water storage tank 201 to replenish water. A through hole is formed at the lower end of the outer arc surface of the water storage tank 201 to connect it to the connecting pipe 202. A rectangular groove is formed at the lower end of the connecting pipe 202 to accommodate the piston movement of the baffle 204 at its lower end. The upper end of the baffle 204... Two sets of rectangular protrusions are provided, so that the baffle 204 cannot be dislodged from the connecting pipe 202 during movement. The upper end of the inner surface of the connecting pipe 202 is provided with a rectangular groove, so that the baffle 204 can be inserted here and its movement direction is limited. Two sets of connecting rods 205 are provided, and the two sets of connecting rods 205 are stacked and distributed with the center line of the linkage plate 203 as the axis of symmetry. The connecting rods 205 are designed as an L-shape, so that they can extend into the lower end of the cover plate 304 and slide to connect with the cover plate 304. The outer surface of the float plate 206 is slidably connected to the water bath 1.

[0020] Reference Figures 4-5 The chamber partitioning device 3 includes a partition plate 303, a magnetic plate 301 is fixedly connected to the upper end of the partition plate 303, a cover plate 304 is slidably connected to the outer surface of the partition plate 303, a fixed shaft 305 is fixedly connected to the lower end of the cover plate 304, an outer shaft 306 is rotatably connected to the outer arc surface of the fixed shaft 305, and a baffle plate 302 is fixedly connected to the lower end of the outer arc surface of the outer shaft 306.

[0021] Multiple sets of partition plates 303 are provided, and the spacing between the multiple sets of partition plates 303 is equal. Therefore, the partition plates 303 can divide the interior of the water bath 1 into multiple chambers. The partition plates 303 are connected to the piston of the water bath 1, so that after dividing the interior of the water bath 1, adjacent chambers cannot communicate with each other. The inner surface of the cover plate 304 has multiple sets of through holes, so that multiple sets of partition plates 303 can be inserted. The lower surface of the cover plate 304 is provided with an arc-shaped groove, so that the outer shaft 306 can rotate here. The lower surface of the cover plate 304 is provided with multiple sets of rectangular grooves, so that... The cover plate 304 is designed to accommodate the baffle plate 302 rotating to this position and to block the through hole inside the cover plate 304. The outer arc surface of the fixed shaft 305 is elastically connected to the outer shaft 306 via a spiral spring. This allows the spiral spring to generate a force that rotates the outer shaft 306 and the baffle plate 302 toward the cover plate 304 through its own elastic force. The center of the inner surface of the outer shaft 306 has a through hole, which allows it to be rotatably connected to the fixed shaft 305. The length of the baffle plate 302 is the same as the width of the rectangular groove at the lower end of the cover plate 304, thus allowing the baffle plate 302 to fully block the through hole inside the cover plate 304.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
