Description

Technical Field

[0001] This utility model relates to the technical field of medical endoscope storage equipment, and in particular to an endoscope storage cabinet. Background Technology

[0002] Endoscope storage cabinets are used to store medical endoscopes, and are therefore commonly used in hospitals. The internal storage environment of an endoscope storage cabinet typically needs to be kept dry and clean. They are designed with multiple layers, each capable of storing different types of endoscopes. The cabinets also have doors to ensure the safe, effective, and convenient transfer and use of endoscopes, and to allow doctors to quickly locate the necessary equipment, improving work efficiency and diagnostic accuracy.

[0003] Existing endoscope storage cabinets typically use cylinders or door-opening push rods to control the opening and closing of the cabinet door. For example, Chinese utility model patent CN221285910U, entitled "An Endoscope Clean Storage Cabinet," includes an outer shell and an inner frame. The front of the outer shell is embedded with an intelligent controller and has a cabinet door. The right side of the inner frame has a storage compartment. A door-opening push rod is provided between the outer shell and the cabinet door. The intelligent controller opens the cabinet door by controlling the extension and retraction of the door-opening push rod. In actual use, the door-opening push rod needs to be driven and controlled by a motor, and the movement of the motor is controlled by the intelligent controller sending commands.

[0004] In addition, in the existing technology, when the endoscope storage cabinet uses a cylinder to control the opening and closing of the cabinet door, an air compressor is usually used as the driving power source, and the air pressure of the air compressor used needs to reach more than 2.0MPa to meet the needs of driving the cylinder to open the cabinet door.

[0005] However, the existing technology still has the following drawbacks:

[0006] The existing technology uses an intelligent controller to control the motor to drive the door push rod to control the opening and closing of the cabinet door. Both the intelligent controller and the motor are relatively expensive, resulting in a high manufacturing cost for the endoscope storage cabinet. When a fault occurs, it also requires professional personnel to debug and repair, which makes the maintenance cost relatively high.

[0007] In addition, when using an air compressor to drive the cylinder to control the opening and closing of the endoscope storage cabinet door, an air compressor with an air pressure of more than 2.0MPa is required, so the cost is relatively high; moreover, when using an air compressor to drive the control, vibration will be generated, resulting in a lot of noise when opening and closing the door, which cannot meet the hospital's requirements for a quiet environment. Utility Model Content

[0008] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an endoscope storage cabinet.

[0009] The objective of this utility model is achieved through the following technical solution: an endoscope storage cabinet, comprising a cabinet body and an opening and closing control mechanism, wherein a cabinet door is provided on the front of the cabinet body, and the opening and closing control mechanism is provided on the cabinet body, and the opening and closing control mechanism has a micro air supply device, a first solenoid valve and an opening cylinder; the first solenoid valve has an air inlet and an air outlet, the opening cylinder has a retraction air outlet and an extension air outlet, the piston rod of the opening cylinder is movably connected to the cabinet door, the air supply end of the micro air supply device is connected to the air inlet of the first solenoid valve, and the air outlet of the first solenoid valve is connected to the retraction air outlet and the extension air outlet of the opening cylinder; so that the micro air supply device supplies air to the opening cylinder through the first solenoid valve and the extension air outlet to gradually open the cabinet door, or so that the micro air supply device supplies air to the opening cylinder through the first solenoid valve and the retraction air outlet to gradually close the cabinet door.

[0010] Further, the air outlet includes a first air outlet and a second air outlet; the first solenoid valve also has a first exhaust port and a second exhaust port, the first air outlet is connected to the contraction air outlet, and the second air outlet is connected to the extension air outlet; so that the micro gas delivery device sequentially inputs gas into the contraction chamber of the opening cylinder through the air inlet, the first air outlet and the contraction air outlet, and the gas in the extension chamber of the opening cylinder is sequentially discharged through the extension air outlet, the second air outlet and the second exhaust port; and the micro gas delivery device sequentially inputs gas into the extension chamber of the opening cylinder through the air inlet, the second air outlet and the extension air outlet, and the gas in the contraction chamber of the opening cylinder is sequentially discharged through the contraction air outlet, the first air outlet and the first exhaust port.

[0011] Furthermore, the opening and closing control mechanism also includes a second solenoid valve and a third solenoid valve, which are respectively disposed at the first exhaust port and the second exhaust port. When the cabinet door is opened, the second solenoid valve is controlled to close and the third solenoid valve is controlled to open, and the third solenoid valve controls the exhaust volume and exhaust speed of the extension chamber of the door opening cylinder. When the cabinet door is closed, the second solenoid valve is controlled to open and the third solenoid valve is controlled to close, and the second solenoid valve controls the exhaust volume and exhaust speed of the retraction chamber of the door opening cylinder.

[0012] Furthermore, the first solenoid valve is configured as a three-position five-way solenoid valve, and the second and third solenoid valves are configured as two-position two-way solenoid valves.

[0013] Furthermore, the pressure of the micro gas delivery device is 0.4-0.6 MPa.

[0014] Furthermore, the cabinet bottom is provided with several partitioned slots, and the micro gas delivery device, the first solenoid valve, the second solenoid valve and the third solenoid valve are located in the partitions at the bottom of the cabinet.

[0015] Furthermore, the cabinet body has a bottom groove on its exterior bottom. The bottom groove extends from the back of the cabinet body towards the front and has an opening on one side of the front of the cabinet body. The door opening cylinder is located in the bottom groove and the piston rod extends out of the opening of the bottom groove and is movably connected to the cabinet door.

[0016] Furthermore, a foot switch is provided on the front of the cabinet, which is electrically connected to the micro gas delivery device and controls the start and stop of the micro gas delivery device.

[0017] Furthermore, the cabinet is equipped with several layers of trays for storing endoscopes.

[0018] Furthermore, a power module is provided inside the cabinet, and a drying module, a disinfection module, and a sensing module for sensing the humidity and temperature inside the cabinet are provided for each layer of the tray, which are electrically connected to the power module.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0020] (1) The endoscope storage cabinet of this application replaces the previous endoscope storage cabinet implementation method of using an intelligent controller to control the motor to drive the door push rod to control the opening and closing of the cabinet door, or using a 2.0MPa air compressor to drive the cylinder to control the opening and closing of the cabinet door by setting a miniature air supply device and a first solenoid valve. This saves more on the production and manufacturing cost of the endoscope storage cabinet and reduces maintenance and repair costs. Furthermore, the optimized air path design between the miniature air supply device and the first solenoid valve, as well as the control of the door opening cylinder, reduces the failure rate and improves the smoothness of the opening and closing of the endoscope storage cabinet door. Moreover, the miniature air supply device and the first solenoid valve are relatively small in size, which is convenient for installation and saves the internal space utilization area of ​​the endoscope storage cabinet, eliminating the need for a bulky endoscope storage cabinet.

[0021] (2) By correspondingly setting a second solenoid valve and a third solenoid valve on the first exhaust port and the second exhaust port of the first solenoid valve, the second solenoid valve adjusts the exhaust volume and exhaust speed of the contraction chamber of the door opening cylinder, and the third solenoid valve adjusts the exhaust volume and exhaust speed of the contraction chamber of the door opening cylinder; compared with the previous implementation method of using an air compressor to drive a cylinder to control the opening and closing of the endoscope storage cabinet door, the embodiment of this application can improve the exhaust smoothness when the door opening cylinder controls the opening and closing of the cabinet door, reduce the noise of the endoscope storage cabinet door opening and closing, and provide a quiet working environment for the daily use of endoscope storage cabinets in hospitals and other medical places.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0034] like Figure 1-7As shown, an endoscope storage cabinet is used in hospitals and other medical facilities to store medical instruments such as endoscopes. This allows doctors to quickly locate the required endoscopes by opening the cabinet door 101, thereby improving work efficiency and diagnostic accuracy. The endoscope storage cabinet includes a cabinet body 10 and an opening / closing control mechanism 20. The cabinet body 10 has several vertically arranged trays 40 for storing endoscopes. Optional brackets 103 for supporting the trays 40 can be installed on both side walls of the cabinet body 10, allowing users to easily remove and place the entire tray 40, further enhancing the convenience of accessing and storing endoscopes.

[0035] Since the endoscope storage cabinet operates 24 hours a day, certain requirements are placed on the internal environment of its cabinet 10. Therefore, based on the arrangement of the trays 40 on each layer inside the cabinet 10, a drying module 60, a disinfection module 70, and a sensing module 80 are installed on the inner side wall of the cabinet 10 and between adjacent trays 40. The disinfection module 70 can be an ultraviolet lamp, which disinfects the internal environment of the cabinet 10 and the endoscopes. The drying module 60 can be a ventilation fan or other air blowing device, which dries the moisture inside the disinfected endoscope lenses to prevent water stains. The sensing module 80 includes at least a humidity sensor for sensing the humidity inside the cabinet 10 and a temperature sensor for sensing the temperature inside the cabinet 10.

[0036] The front of the cabinet 10 is provided with a cabinet door 101, and a transparent glass 1011 is provided on the cabinet door 101 so that users can see the storage status of the endoscopes inside the cabinet through the glass. In addition, a display screen 90 is provided on the cabinet door 101 to display information such as the internal temperature, humidity, and disinfection status of the endoscope storage cabinet.

[0037] The cabinet bottom 102 of the cabinet body 10 has several separated compartments 1021 inside, and a power module 50 is installed in each compartment 1021. The power module 50 is electrically connected to the aforementioned drying module 60, disinfection module 70, sensing module 80, and display screen 90. The bottom 102 of the cabinet body 102 has a bottom groove 1022 on the outside, which extends from the back of the cabinet body 10 to the front. The bottom groove 1022 has an opening on one side of the front of the cabinet body 10, thus forming the overall structure of the cabinet body 10.

[0038] The opening and closing control mechanism 20 is installed on the cabinet 10, and the opening and closing control mechanism 20 has a micro air supply device 201, a first solenoid valve 202, a second solenoid valve 203, a third solenoid valve 204 and a door opening cylinder 205. The micro air supply device 201, the first solenoid valve 202, the second solenoid valve 203 and the third solenoid valve 204 are all installed in the partition groove 1021 of the cabinet bottom 102. The door opening cylinder 205 is installed in the bottom groove 1022 of the cabinet bottom 102 and its piston rod 2053 extends out of the groove opening of the bottom groove 1022 and is movably connected to the cabinet door 101. Then, the door opening and closing is driven by the extension and retraction of the piston rod 2053 of the door opening cylinder 205. In this way, by setting partition groove 1021 and bottom groove 1022 on the bottom of cabinet 102, the micro air supply device 201, the first solenoid valve 202, the second solenoid valve 203, the third solenoid valve 204 and the door opening cylinder 205 can be reasonably assembled, which not only makes the overall structure of cabinet 10 more compact, but also avoids interference between components.

[0039] A foot switch 30 is provided on the front of the cabinet 10 and near the bottom 102. The foot switch 30 is electrically connected to the micro air supply device 201 and controls the start and stop of the micro air supply device 201. When in use, the user can control the opening and closing of the cabinet door 101 by stepping on the foot switch 30, so as to free up the user's hands to pick up and put down the tray 40 and the endoscope.

[0040] The miniature air delivery device 201 provided in this application embodiment can use a miniature air pump, and its pressure is set to 0.4-0.6MPa, preferably 0.5MPa, which further saves the internal space of the cabinet 10 and improves the structural compactness of the cabinet 10, and also reduces the manufacturing cost of the endoscope storage cabinet.

[0041] The first solenoid valve 202 is a three-position five-way solenoid valve. Therefore, the first solenoid valve 202 has an air inlet 2021, a first air outlet 2022, a second air outlet 2023, a first exhaust port 2024, and a second exhaust port 2025. The air inlet 2021 of the first solenoid valve 202 is connected to the air supply end of the micro gas delivery device 201, and gas is delivered to the air inlet 2021 of the first solenoid valve 202 through the micro gas delivery device 201.

[0042] The door opening cylinder 205 is a linear telescopic cylinder. The door opening cylinder 205 has a retraction port 2054 and an extension port 2055. The retraction port 2054 communicates with the retraction chamber 2051 of the door opening cylinder 205, and the extension port 2055 communicates with the extension chamber 2052 of the door opening cylinder 205. Furthermore, the retraction port 2054 of the door opening cylinder 205 is also connected to the first outlet port 2022 of the first solenoid valve 202, and the extension port 2055 of the door opening cylinder 205 is also connected to the second outlet port 2023 of the first solenoid valve 202.

[0043] Based on the design principle of the first solenoid valve 202 as a three-position five-way solenoid valve, when the micro gas delivery device 201 delivers gas to the inlet 2021 of the first solenoid valve 202, and the left coil of the first solenoid valve 202 is energized while the right coil is de-energized, at this time, the inlet 2021 is connected to the first outlet 2022, the inlet 2021 is disconnected from the second outlet 2023, the first outlet 2022 is disconnected from the first exhaust port 2024, and the second outlet 2023 is connected to the second exhaust port 2025. Therefore, the gas delivered by the micro gas delivery device 201 can enter the contraction chamber 2051 of the opening cylinder 205 in sequence through the inlet 2021, the first outlet 2022 and the contraction port 2054, while the gas in the extension chamber 2052 can be discharged in sequence through the extension port 2055, the second outlet 2023 and the second exhaust port 2025.

[0044] Similarly, when the right coil of the first solenoid valve 202 is energized and the left coil is de-energized, the air inlet 2021 is connected to the second air outlet 2023, the air inlet 2021 is disconnected from the first air outlet 2022, the first air outlet 2022 is connected to the first exhaust port 2024, and the second air outlet 2023 is disconnected from the second exhaust port 2025. Therefore, the gas delivered by the micro gas delivery device 201 can enter the extension chamber 2052 of the door opening cylinder 205 in sequence through the air inlet 2021, the second air outlet 2023 and the extension air outlet 2055, while the gas in the contraction chamber 2051 can be discharged in sequence through the contraction air outlet 2054, the first air outlet 2022 and the first exhaust port 2024.

[0045] Preferably, both the second solenoid valve 203 and the third solenoid valve 204 are two-position two-way solenoid valves. Therefore, the second solenoid valve 203 and the third solenoid valve 204 are respectively provided with an air inlet and an air outlet. In actual use, the second solenoid valve 203 is set on the first air outlet 2024, and the third solenoid valve 204 is set on the second air outlet 2025. Therefore, when the contraction chamber 2051 of the door-opening cylinder 205 exhausts air, the exhaust volume and exhaust speed of the contraction chamber 2051 of the door-opening cylinder 205 are adjusted by the second solenoid valve 203; when the extension chamber 2052 of the door-opening cylinder 205 exhausts air, the exhaust volume and exhaust speed of the contraction chamber 2051 of the door-opening cylinder 205 are adjusted by the third solenoid valve 204. Compared with the previous implementation method of using an air compressor to drive the cylinder to control the opening and closing of the endoscope storage cabinet door 101, the embodiment of this application can improve the exhaust smoothness when the door-opening cylinder 205 controls the opening and closing of the cabinet door 101, reduce the noise of the opening and closing of the endoscope storage cabinet door 101, and provide a quiet working environment for the daily use of the endoscope storage cabinet in hospitals and other medical places.

[0046] Therefore, based on the design principles of the aforementioned miniature gas delivery device 201, first solenoid valve 202, second solenoid valve 203, third solenoid valve 204, and door opening cylinder 205, the embodiment of this application provides the following method for controlling the opening and closing of the endoscope storage cabinet door 101:

[0047] When the cabinet door 101 is opened, the left coil of the micro gas supply device 201 is energized by stepping on the foot switch 30, and gas is supplied to the air inlet 2021 of the first solenoid valve 202. The gas then passes through the first air outlet 2022 and the contraction air outlet 2054 in sequence and enters the contraction chamber 2051 of the door opening cylinder 205. In addition, the gas in the extension chamber 2052 of the door opening cylinder 205 flows out through the extension air outlet 2055, and then passes through the second air outlet 2023 and the second exhaust outlet 2025 in sequence. The exhaust volume and exhaust speed are controlled by the third solenoid valve 204, thereby adjusting the rhythm of the air pressure pushing the piston rod 2053 of the door opening cylinder 205 to extend outward, so as to gradually push the cabinet door 101.

[0048] When the cabinet door 101 is closed, the right coil of the micro gas supply device 201 is energized by stepping on the foot switch 30, and gas is supplied to the air inlet 2021 of the first solenoid valve 202. The gas then passes through the second air outlet 2023 and the extension air outlet 2055 in sequence and enters the extension chamber 2052 of the door opening cylinder 205. In addition, the gas in the contraction chamber 2051 of the door opening cylinder 205 flows out through the contraction air outlet 2054, and then passes through the first air outlet 2022 and the first exhaust outlet 2024 in sequence. The exhaust volume and exhaust speed are controlled by the second solenoid valve 203, thereby adjusting the rhythm of the piston rod 2053 of the door opening cylinder 205 retracting inward, so as to gradually close the cabinet door 101.

[0049] Thus, the endoscope storage cabinet in this embodiment of the application, by setting up a miniature air supply device 201 and a first solenoid valve 202, replaces the previous implementation method of using an intelligent controller to control a motor to drive a door opening push rod to control the opening and closing of the cabinet door 101, or using a 2.0MPa air compressor to drive a cylinder to control the opening and closing of the cabinet door 101. This saves on the manufacturing cost of the endoscope storage cabinet and reduces maintenance and repair costs. Furthermore, by optimizing the air path design between the miniature air supply device 201 and the first solenoid valve 202, and controlling the door opening cylinder 205, the failure rate is reduced and the smoothness of the opening and closing of the endoscope storage cabinet door 101 is improved. Moreover, the miniature air supply device 201 and the first solenoid valve 202 are relatively small in size, which is convenient for installation and saves the internal space utilization area of ​​the endoscope storage cabinet, eliminating the need for a bulky endoscope storage cabinet.

[0050] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
