Description

Technical Field

[0001] This utility model relates to the field of medical disinfection equipment technology, and in particular to a disinfection cabinet. Background Technology

[0002] A TEE (Transesophageal Echocardiography) probe is a high-precision medical device specifically designed for examining the structures of the heart and major blood vessels. During use, the insertion of the TEE probe into the esophagus is similar to that of an electronic gastroscopy. After the probe is safely inserted into the esophagus, its depth within the esophagus is adjusted by advancing, retreating, rotating, and bending forward, backward, left, and right, allowing for the examination of the heart and major blood vessel structures from superficial to deep.

[0003] The TEE probe mainly consists of a transducer at the probe tip, a flexible tube, and a handle. The TEE probe is equipped with a dedicated sterilization cabinet for sterilization of all the above parts, allowing the TEE probe to be reused and preventing cross-infection when different patients use the same TEE probe.

[0004] Common disinfection cabinets use ultraviolet (UV) disinfection, which is achieved by disinfection lamps on various sides of the disinfection chamber irradiating the surfaces of the probes. The heat generated when multiple UV lamps operate simultaneously is significant. In existing disinfection cabinets, the cooling fans for the UV lamps are typically located on the left and right sides of the disinfection chamber. During heat dissipation, airflow exits from the rear of the cabinet, with a small portion of the airflow passing over the rear of the disinfection chamber. This results in insufficient heat dissipation for the UV lamps at the rear of the chamber. Utility Model Content

Multiple heat sink assemblies are mounted on the outer surface of the disinfection structure and arranged circumferentially along the disinfection structure. A flow guiding structure is installed in the cavity and disposed on the outer periphery of the disinfection structure. A heat dissipation air duct is formed between the flow guiding structure and the disinfection structure. An air outlet is opened at the rear end of the flow guiding structure. The air outlet is aligned with the heat dissipation fin group located on the rear side of the disinfection structure and is connected to the exhaust port. Multiple mounting ports are opened on the left and right sides of the flow guiding structure, and the mounting ports are connected to the heat dissipation air duct. Multiple first cooling fans, each of which is installed in one of the mounting ports.

[0006] In some embodiments of this utility model, the airflow guiding structure includes two airflow guiding plates. Each airflow guiding plate includes a main plate and an airflow guiding portion. The main plates of the two airflow guiding plates are respectively spaced apart on the left and right sides of the disinfection structure. The airflow guiding portion is connected to the rear edge of the main plate and extends in a direction close to each other in a direction away from the airflow guiding portion. The two airflow guiding portions are spaced apart on the side away from the main plate to form the air outlet.

[0007] In some embodiments of this utility model, the rear ends of the two flow guides are bent in a direction away from the disinfection structure to form a reinforcing portion.

[0008] In some embodiments of this utility model, the two reinforcing portions extend in opposite directions away from the disinfection structure to form a flare.

[0009] In some embodiments of this utility model, the expansion angle of the flared opening is greater than or equal to 110 degrees and less than or equal to 165 degrees.

[0010] In some embodiments of this utility model, the ratio of the width of the air outlet to the width of the disinfection structure in the left-right direction of the cabinet is greater than or equal to 1 / 5 and less than or equal to 4 / 5.

[0011] In some embodiments of this utility model, the flow guiding structure further includes two baffles. One of the baffles is connected between the flow guiding part and the cavity wall of the cavity, and forms an exhaust duct. The exhaust duct is connected between the air outlet and the exhaust port.

[0012] In some embodiments of this utility model, the disinfection structure includes multiple panels, which are located within the cavity and enclose the disinfection cavity, and a heat sink assembly is installed on the outside of one of the panels.

[0014] In some embodiments of this utility model, a cavity is formed inside the cabinet door, and ventilation holes are provided in the cavity wall. The disinfection cabinet also includes a second cooling fan, which is installed inside the cabinet door and faces the panel installed on the cabinet door.

[0015] Through the above-described solution, when the disinfection cabinet is working, the cooling fan drives the airflow to enter through the air inlet of the cabinet, and after passing through the cavity, it flows into the guide channel. In the guide channel, since the air outlet is aligned with a heat sink group located on one side of the disinfection structure, the airflow can flow through each heat sink group, fully absorb the heat of the heat sink group, and finally be discharged from the air outlet, resulting in higher heat dissipation efficiency and more uniform heat dissipation effect.

[0023] Please see Figures 1 to 5 This utility model proposes a disinfection cabinet 100, including a cabinet body 10, a disinfection structure 20, multiple heat sink assemblies 30, a flow guiding structure 40, and multiple first cooling fans 51. The cabinet body 10 has a cavity 101, and the cavity wall of the cavity 101 has an air inlet 102 and an air outlet 103. The disinfection structure 20 is disposed within the cavity 101, forming a sealed disinfection chamber 21. Multiple heat sink assemblies 30 are installed on the outer surface of the disinfection structure 20 and arranged circumferentially along the disinfection structure 20. The airflow guiding structure 40 is installed in the cavity 101 and located on the outer periphery of the disinfection structure 20. A heat dissipation air duct is formed between the airflow guiding structure 40 and the disinfection structure 20. An air outlet 44 is opened at the rear end of the airflow guiding structure 40. The air outlet 44 is aligned with the heat sink assembly 30 located on the rear side of the disinfection structure 20 and is connected to the exhaust port 103. Multiple mounting ports 411 are opened on the left and right sides of the airflow guiding structure 40, and the mounting ports 411 are connected to the heat dissipation air duct. A first cooling fan 51 is installed in one mounting port 411.

[0024] Through the above-described solution, when the disinfection cabinet 100 is working, the cooling fan drives the airflow to enter through the air inlet 102 of the cabinet 10, and after passing through the cavity 101, it flows into the guide channel. In the guide channel, since the air outlet 44 is aligned with a heat sink group 30 located on one side of the disinfection structure 20, the airflow can flow through each heat sink group 30, fully absorb the heat of the heat sink group 30, and finally be discharged from the air outlet 44. The heat dissipation efficiency is higher and the heat dissipation effect is more uniform.

[0025] The aforementioned flow guiding structure 40 is generally made of metal, such as aluminum alloy, which is relatively lightweight, or stainless steel. No limitation is made here. The flow guiding structure 40 is generally tubular or formed by splicing multiple plates. In some embodiments of this utility model, the flow guiding structure 40 includes two flow guiding plates 41. Each flow guiding plate 41 includes a main plate portion 413 and a flow guiding portion 414. The main plate portions 413 of the two flow guiding plates 41 are respectively spaced apart on the left and right sides of the disinfection structure 20. The flow guiding portion 414 is connected to the rear edge of the main plate portion 413 and extends in a direction close to each other in a direction away from the flow guiding portion 414. The two flow guiding portions 414 are spaced apart on the side away from the main plate portion 413 to form an air outlet 44. The flow guide structure 40 is designed as a plate, which is convenient for processing and manufacturing. During assembly, the cooling fan can be installed on the corresponding flow guide plate 41 first, and then installed together in the cavity 101 to achieve modular installation and improve assembly efficiency. During maintenance, the structure installed on a flow guide plate 41 can be maintained independently, which is more convenient.

[0026] Furthermore, considering that the airflow guide 414 experiences significant wind pressure during heat dissipation, and because it obstructs airflow, it is prone to vibration under the influence of airflow, causing noise from the disinfection cabinet 100. Therefore, in some embodiments of this invention, the rear ends of the two airflow guides 414 are bent away from the disinfection structure 20 to form reinforcing portions 412. In this way, supported by the reinforcing portions 412, the overall strength of the airflow guide structure 40 is increased, making it more stable and durable, and suppressing noise caused by vibration of the airflow guides 414.

[0027] The aforementioned reinforcing portion 412 can be bent into an acute angle, a right angle, or an obtuse angle. In some embodiments of this utility model, the two reinforcing portions 412 extend in opposite directions away from the disinfection structure 20 to form a flared opening 45. This extension of the reinforcing portion 412 to form the flared opening 45 not only enhances the strength of the airflow guiding structure 40 but also improves its resistance to deformation, ensuring the stability of the airflow guiding structure 40 under various working environments. It also improves airflow, allowing more air to be discharged through the air outlet 44, which helps improve heat dissipation efficiency, especially under high load or long-term working conditions.

[0028] Please see Figure 5 Considering that an excessively large expansion angle α of the flared opening 45 would reduce the pressure resistance of the guide section 414, while an excessively small expansion angle α would result in poor airflow, in some embodiments of this utility model, the expansion angle α of the flared opening 45 is greater than or equal to 110 degrees and less than or equal to 165 degrees. Specifically, it can be 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 165 degrees, etc.

[0029] Furthermore, considering that if the width of the air outlet 44 is too large, the heat sink aligned with the air outlet 44 may only experience a small airflow, while if the width of the air outlet 44 is too small, airflow may be obstructed, therefore, in some embodiments of this utility model, the ratio of the width of the air outlet 44 to the width of the disinfection structure 20 in the left-right direction of the cabinet 10 is greater than or equal to 1 / 5 and less than or equal to 4 / 5. Specifically, it can be 1 / 5, 2 / 5, 3 / 5, 4 / 5, etc. The expansion angle of the flare 45 and the width of the air outlet 44 can be set according to specific circumstances and are not limited here.

[0030] Furthermore, in some embodiments of this utility model, the flow guiding structure 40 further includes two baffles 42. One baffle 42 is connected between a flow guiding part 414 and the cavity wall of the cavity 101, forming an exhaust duct 43. The exhaust duct 43 connects the air outlet 44 and the exhaust port 103. Through the above solution, the baffle 42 can not only be used to guide hot airflow, but also provide support for the flow guiding part 414, thereby enhancing the stability and practicality of the structure.

[0031] There are various specific implementations of the disinfection structure 20. In some embodiments of this utility model, the disinfection structure 20 is a cylindrical metal tube with disinfection lamps 23 installed on the tube wall. Preferably, in some embodiments of this utility model, the disinfection structure 20 includes multiple panels 22 located within the cavity 101 and forming a disinfection chamber 21. A heat sink assembly 30 is installed on the outer side of one panel 22. The surface of the panel 22 is relatively flat, facilitating the installation of equipment such as disinfection lamps 23. Furthermore, the multiple panels 22 allow the disinfection lamps 23 installed on each panel 22 to comprehensively disinfect the equipment to be disinfected.

[0032] The cabinet body 10 is generally configured with a side-opening cabinet door 12. Of course, a top-opening cabinet door 12 can also be used, depending on the specific situation. In some embodiments of this utility model, the cabinet body 10 includes a cabinet body 11 and a cabinet door 12. The cabinet door 12 is hinged to the front side of the cabinet body 11 and forms a cavity 101 with the cabinet body 11. One panel 22 is connected to the cabinet door 12, and the other panels 22 are connected to the cabinet body 11. The flow guiding structure 40 is installed inside the cabinet body 11. This allows the disinfection cabinet 100 to maintain ease of operation while also achieving good sealing performance.

[0033] In some embodiments of this utility model, a cavity 121 is formed inside the cabinet door 12, and ventilation holes 122 are provided in the cavity wall of the cavity 121. The disinfection cabinet 100 also includes a second cooling fan 52, which is installed inside the cabinet door 12 and faces the panel 22 installed on the cabinet door 12. The design of providing ventilation holes 122 and installing the second cooling fan 52 in the cavity 121 inside the cabinet door 12 not only improves the heat dissipation efficiency of the disinfection cabinet 100, but also helps to maintain the disinfection effect and equipment safety, enabling the disinfection module of the cabinet door 12 to operate at a constant temperature like the disinfection module of the cabinet body 10.

[0034] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
