Description

Technical Field

[0001] This utility model belongs to the technical field of stability testing equipment, specifically relating to an automatic water supply device for a pharmaceutical stability testing chamber. Background Technology

[0002] A drug stability test chamber is an instrument used to measure the long-term stable temperature, humidity, and light environment required for drug efficacy assessment. For example... Figure 1 As shown, the humidification system of existing drug stability test chambers mainly uses electric heating tube 1 to heat pure water in heating tank 2, turning the water into water vapor, thereby creating a humid environment inside the test chamber. The heating tank is connected to a water storage tank 4 outside the test chamber via a connecting pipe 3, forming a communicating vessel structure. When the water level in the water storage tank 4 continuously decreases, it is manually replenished or automatically replenished by a water pump. Because the water in the water storage tank remains static for a long time, it is prone to bacterial growth and the formation of flocculent matter. This not only affects the accuracy of the test results but also causes blockage of the connecting pipe, leading to a situation where the heating tank runs dry and burns out, causing equipment damage. To avoid the above situations, the test personnel need to clean and maintain the water storage tank regularly, which is quite troublesome. Utility Model Content

[0003] This invention addresses the shortcomings of the prior art by providing an automatic water supply device for a pharmaceutical stability test chamber. A circulating water tank is added between the heating tank and the storage tank to keep the water flowing between the circulating water tank and the storage tank. This improves the situation of bacterial growth and flocculent formation in traditional static water, reduces the risk of dry burning due to water shortage, and reduces the frequency of cleaning and maintenance of the storage tank.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: An automatic water supply device for a drug stability test chamber includes a heating tank, a water storage tank, and a circulating water tank. A connecting pipe is provided between the circulating water tank and the heating tank to form a communicating vessel structure. An overflow hole is provided on one side of the circulating water tank. A return pipe is connected between the overflow hole and the water storage tank. A water injection pipe is provided in the water storage tank. A water pump is provided on the water injection pipe. The water injection pipe is connected to the water inlet of the circulating water tank.

[0005] Preferably, the circulating water tank includes a tank body and a top cover, and fixing blocks are provided at the four top corners of the tank body. The top cover and the fixing blocks are connected by screws.

[0006] Preferably, the box body has wing plates on both sides, and the wing plates have waist-shaped mounting holes.

[0007] Preferably, the box body and the top cover are both made of transparent material.

[0008] Preferably, a drain pipe is connected to the bottom of the heating pool, and a control valve is provided on the drain pipe.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: (1) This utility model adds a circulating water tank between the heating pool and the water storage pool, so that the water between the circulating water tank and the water storage pool is kept in a flowing state, which improves the situation of bacteria growth and flocculent matter in traditional static water, reduces the risk of dry burning due to water shortage, and reduces the frequency of cleaning and maintenance of the water storage pool. (2) Based on the principle of communicating vessels, this utility model can adjust the installation height of the circulating water tank by adjusting the installation height of the waist-shaped mounting hole, thereby realizing the height adjustment of the required liquid level in the heating pool. It is simple to operate and highly practical. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0013] In the description of this utility model, it should be understood that the terms "middle", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 this utility model.

[0014] In this utility model, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," "link," and "fix" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection; a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0015] like Figure 2 As shown, an automatic water supply device for a drug stability test chamber includes a heating pool 2, a water storage pool 4, and a circulating water tank 5. A connecting pipe 3 is provided between the circulating water tank and the heating pool to form a communicating vessel structure. An overflow hole 6 is provided on one side of the circulating water tank. A return pipe 7 is connected between the overflow hole and the water storage pool. A water injection pipe 8 is provided in the water storage pool. A water pump 9 is provided on the water injection pipe. The water injection pipe is connected to the water inlet 10 of the circulating water tank. The liquid level in the water storage pool is lower than the height of the overflow hole of the circulating water tank. When water is added to the circulating water tank 5, the water in the circulating water tank 5 will automatically flow into the heating pool 2 through the connecting pipe 3 under atmospheric pressure until the liquid level in the circulating water tank 5 and the heating pool 2 are consistent. At this time, water is added to the circulating water tank 5. After the liquid level reaches the position of the overflow hole 6, the excess water is discharged into the storage tank 4 through the overflow hole 6 and the return pipe 7. The water in the storage tank 4 is continuously fed into the circulating water tank 5 through the water injection pipe 8 and the water injection port 10 under the action of the water pump 9, thereby forming a circulating water that is always in motion. This improves the situation of bacteria growth and flocculent formation in traditional static water, reduces the risk of dry burning due to water shortage, and reduces the frequency of cleaning and maintenance of the storage tank.

[0016] Combination Figure 3 and Figure 4 As shown, the circulating water tank includes a tank body 501 and a top cover 502. Fixing blocks 16 are located at the four corners of the tank body. The top cover and fixing blocks are connected by screws 11. Both the tank body and the top cover are made of transparent material; in this embodiment, acrylic is used to facilitate observation of the internal condition of the circulating water tank. The fixing blocks can be integrated with the tank body, and the top cover can cover the tank body to prevent external impurities from falling into the tank. The screw connection facilitates disassembly and maintenance, making operation simple and convenient. Wing plates 12 are located on both sides of the tank body, with waist-shaped mounting holes 13 on the wing plates. In practical applications, the circulating water tank can be installed on the outer wall of the test chamber. The waist-shaped mounting holes facilitate screw or bolt connection, and the liquid level in the heating pool can be adjusted according to actual needs, making it highly practical. A drain pipe 14 is connected to the bottom of the heating pool, and a control valve 15 is installed on the drain pipe. When the test chamber is not in use, the water in the heating pool can be drained through the control valve.

[0017] The method of use and working principle of this utility model are as follows: like Figures 2 to 4 As shown, the heating tank 2 is installed inside the test chamber, while the circulating water tank 5 and the storage tank 4 are located outside the test chamber. The circulating water tank 5 is fixed to the outer wall of the test chamber via the waist-shaped mounting hole 13 on the wing plate 12. The required liquid level in the heating tank 2 can be adjusted by adjusting the installation height of the circulating water tank 5. The storage tank 4 can be fixed to the outer wall of the test chamber or placed directly on the ground. During operation, when the water level in the heating tank 2 decreases, the water in the circulating water tank 5 will automatically replenish it. Since the water pump 9 works continuously after the power is turned on, it injects pure water from the storage tank 4 into the circulating water tank 5 through the water injection pipe 8 and the water injection port 10. When the liquid level in the circulating water tank 5 is greater than the overflow hole, the excess water is discharged into the storage tank 4 through the overflow hole 6 and the return pipe 7, forming a closed loop. This ensures that the liquid level in the heating tank 2 and the circulating water tank 5 remains constant, guaranteeing the stability of the humidification system in the test chamber. The test personnel only need to monitor the amount of pure water in the storage tank 4 and add water periodically. Because the water in the circulating water tank 5 and the water storage tank 4 is always flowing, the growth of bacteria and the production of flocculent matter are reduced, the risk of water shortage and dry burning is reduced, and the frequency of cleaning and maintenance of the water storage tank 4 is reduced.

[0018] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.
