[0019] The embodiments of this application have the following advantages:

[0020] This application provides a gas delivery device. An air pump assembly, driven by a power source such as a motor, cyclically generates negative and positive pressures, thereby drawing gas in through the inlet and expelling it through the outlet. Gas enters the mounting cavity of the housing assembly from the inlet, then enters the air pump through the air pump assembly's inlet, is compressed, and is discharged from the outlet, ultimately being delivered to the endoscope through the outlet. The gap between the inlet and outlet effectively buffers pressure fluctuations during gas flow, reducing noise generated by the gas flow. The gap also regulates airflow, making it smoother and further reducing noise. The housing assembly not only provides installation space for the air pump assembly but also optimizes the gas flow path through its structural design (such as the mounting cavity, inlet, and outlet), reducing airflow turbulence and noise generation. Furthermore, the gap design and optimized gas flow path make gas delivery smoother, reducing airflow turbulence and pressure fluctuations, and improving gas delivery efficiency.

[0033] In related technologies, medical electronic endoscope processors are used to process image information acquired by the endoscope, while simultaneously supplying illumination light and water and air to the endoscope for cleaning the lens. The power source for the endoscope processor to supply water and air is an air pump. The principle of the air pump pumping air is to generate negative and positive pressure through the circulation of power sources such as motors. This operating mode causes the endoscope processor to generate considerable noise, which affects surgical operations.

[0034] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, this application provides an air supply device, which includes a receiving component 100 and an air pump component 200. The receiving component 100 has a mounting cavity 130, an inlet 170 and an outlet 180, and the inlet 170 and the outlet 180 are respectively connected to the mounting cavity 130. The air pump component 200 is disposed in the mounting cavity 130 and has an air inlet 220 and an exhaust port 230. The air inlet 220 is connected to the mounting cavity 130 and the exhaust port 230 is connected to the outlet 180. A gap is defined between the air inlet 220 and the inlet 170.

[0035] In these embodiments, the aim is to reduce the operating noise of the endoscope processor. The air supply device comprises two main components:

[0036] The receiving assembly 100 includes a mounting cavity 130, an inlet 170, and an outlet 180. The inlet 170 and outlet 180 are respectively connected to the mounting cavity 130, allowing gas to enter and exit. Exemplarily, in this embodiment, the receiving assembly 100 is a box-like structure. Of course, in other embodiments, the receiving assembly 100 may also be a sealed tube, etc. Optionally, the sidewalls of the mounting cavity 130 should be made of a rigid material to prevent deformation of the mounting cavity 130 during air pump operation; this design can further improve noise reduction.

[0037] An air pump assembly 200 is mounted inside a mounting cavity 130 that houses the assembly 100. The air pump assembly 200 includes an air inlet 220 and an air outlet 230. The air inlet 220 communicates with the mounting cavity 130, while the air outlet 230 communicates with an outlet 180. For example, the air pump assembly 200 includes an air pump having an air inlet 220 and an air outlet 230.

[0038] The key feature is the gap between the air inlet 220 and the inlet 170, which optimizes the way gas enters and leaves the air pump, thereby reducing noise caused by direct impact or turbulence. In other words, it prevents gas flowing from inlet 170 into the mounting cavity 130 from directly entering the air inlet 220, allowing the mounting cavity 130 to form an air storage space, facilitating stable airflow and reducing noise diffused outwards from the air inlet 220 due to airflow pulses. It should be noted that the air inlet 220 is exposed within the mounting cavity 130.

[0039] Furthermore, the housing component 100 not only provides an installation space for the air pump, but also plays a certain role in sound insulation, reducing the transmission of noise during the operation of the air pump.

[0040] Clearly, the air pump assembly 200, driven by a power source such as a motor, cyclically generates negative and positive pressures, thereby drawing gas in through the inlet 220 and expelling it through the outlet 230. Gas enters the mounting cavity 130 of the housing assembly 100 through the inlet 170, then enters the air pump interior through the inlet 220, is compressed, and exits through the outlet 230, finally being delivered to the endoscope through the outlet 180. The gap between the inlet 220 and the outlet 170 effectively buffers pressure fluctuations during gas flow, reducing noise generated by the gas flow. The gap also regulates airflow, making the gas flow smoother and further reducing noise. The housing assembly 100 not only provides installation space for the air pump assembly 200 but also optimizes the gas flow path through its structural design (such as the mounting cavity 130, inlet 170, and outlet 180), reducing airflow turbulence and noise generation. Furthermore, the gap design and optimized gas flow path make gas delivery smoother, reducing airflow turbulence and pressure fluctuations, and improving gas delivery efficiency.

[0041] In some embodiments, the opening area of ​​inlet 170 is smaller than the opening area of ​​air inlet 220.

[0042] In these embodiments, the opening area of ​​inlet 170 is smaller than the opening area of ​​air inlet 220 of air pump assembly 200, which is an effective way to optimize airflow path and reduce noise.

[0043] When the opening area of ​​inlet 170 is smaller than that of inlet 220, according to Bernoulli's principle (as fluid velocity increases, static pressure decreases), the gas velocity will increase when it enters the mounting cavity 130 through the smaller inlet 170. This design allows for more precise control of airflow velocity and direction, thereby optimizing airflow management throughout the system.

[0044] The smaller inlet 170 helps to smooth the airflow into the mounting cavity 130, reducing the generation of turbulence. Turbulence is a significant factor contributing to noise, and this method effectively reduces noise caused by unstable airflow.

[0045] An optimized airflow path can improve the efficiency of the air pump. By reducing unnecessary airflow resistance and losses, more energy can be used for actual gas delivery, rather than being wasted on overcoming resistance.

[0046] Furthermore, the small opening area can limit the direct transmission of external noise into the mounting cavity 130 to a certain extent, further enhancing the sound insulation effect of the overall device.

[0047] It should be noted that while a smaller inlet 170 helps control airflow velocity and reduce noise, it is essential to ensure that airflow is not excessively restricted due to an overly small inlet 170, which could lead to decreased pump efficiency or overheating. Therefore, those skilled in the art need to perform detailed calculations and tests to find the optimal opening area ratio.

[0048] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, at opposite ends of the mounting cavity 130, the inlet 170 is located at one end of the mounting cavity 130, and the air inlet 220 is located at the other end of the mounting cavity 130.

[0049] In these embodiments, the inlet 170 is located at one end of the mounting cavity 130, while the air inlet 220 is located at the other end of the mounting cavity 130. This arrangement can further optimize the airflow path, improve system efficiency, and reduce noise.

[0050] By positioning the inlet 170 and the air inlet 220 at opposite ends of the mounting cavity 130, the gas can have a longer flow path after entering the mounting cavity 130. This design helps to distribute the airflow more evenly and reduces local turbulence and pressure unevenness.

[0051] A longer airflow path helps the gas gradually slow down and smooth out during flow, thereby reducing turbulence and impact noise. Furthermore, this layout increases the contact area between the airflow and the walls of the mounting cavity 130, further aiding in noise absorption and attenuation.

[0052] In addition, as the gas flows along a longer path, it has more opportunities to exchange heat with the components inside the mounting cavity 130, thus aiding in heat dissipation. This is crucial for maintaining the operating temperature of the air pump assembly 200 and other electronic components, especially during long-term operation.

[0053] To achieve optimal airflow path and sound insulation, the mounting cavity 130 requires the use of high-quality materials and precise manufacturing processes. For example, a smooth inner wall surface reduces friction and noise, while appropriate material thickness contributes to sound insulation.

[0054] For example, the inlet 170 is located at the bottom of the housing component 100, and the air inlet 220 is located at the top of the housing component 100, reducing the amount of dust or other impurities clogging the airflow passage.

[0055] like Figure 2 As shown, in some embodiments, the air pump assembly 200 also has a hose 210, through which the exhaust port 230 is connected to the inlet 170;

[0056] The air supply device also includes a damping component 300, which is connected to the receiving component 100. An air pump component 200 is disposed on the damping component 300, and the damping component 300 is used to absorb the vibration energy generated by the air pump component 200.

[0057] In these embodiments, the air pump assembly 200 is connected to the inlet 170 via a hose 210, and the air delivery device also includes a damping component 300 to absorb the vibration energy generated by the air pump assembly 200. This further optimizes airflow management, reduces noise, and minimizes the impact of vibration on the overall system.

[0058] Using a flexible hose 210 to connect the exhaust port 230 to the inlet 170 provides a flexible connection method, avoiding stress concentration and potential damage risks caused by rigid connections.

[0059] Furthermore, the hose 210 has a certain degree of flexibility and elasticity, which can isolate the vibration generated by the air pump assembly 200 to a certain extent and prevent these vibrations from being transmitted to the housing assembly 100 or other parts through rigid connections, thereby reducing the vibration and noise of the overall system.

[0060] For example, the hose 210 can be a silicone hose 210, a rubber hose 210, a plastic hose 210, etc. Optionally, when the hose 210 is a corrugated hose 210, the transmission of vibration can be further reduced, and the corrugated hose 210 has a certain shock absorption capacity.

[0061] The damping component 300 is installed between the air pump assembly 200 and the housing assembly 100, and can effectively absorb the vibration energy generated during the operation of the air pump, reducing the transmission of vibration to the external environment. For example, the damping component 300 can be a rubber pad, spring, or shock absorber, etc.

[0062] Therefore, reducing vibration not only helps lower noise but also improves the mechanical stability of the entire system and extends the service life of the equipment. Vibration can damage internal precision components, especially during long-term operation. The vibration damping assembly 300 effectively protects these components, ensuring their long-term stable operation.

[0063] In addition, the vibration damping component 300 can be made of various materials, such as rubber, polyurethane foam, and metal springs. Different materials have different vibration absorption effects and applicable scenarios, and the selection should be made according to specific needs.

[0064] For example, multiple rubber damping pads are installed at the bottom of the air pump assembly 200, with each pad evenly distributed at the four corners or edges of the air pump assembly 200. These damping pads can effectively absorb the vertical and horizontal vibrations generated during air pump operation.

[0065] Furthermore, a layer of polyurethane foam pad can be added between the air pump assembly 200 and the housing assembly 100 to further enhance the vibration absorption effect.

[0066] like Figure 1 and Figure 2 As shown, in some embodiments, the receiving component 100 has a silencing cavity 150 and a communication port 140, an outlet 180 is connected to the silencing cavity 150, and an exhaust port 230 is connected to the silencing cavity 150 through the communication port 140.

[0067] In these embodiments, the silencing cavity 150 is a structure used to absorb and attenuate noise in the airflow. The silencing cavity 150 can act as a buffer, allowing the high-speed airflow to slow down and smooth before entering the outlet 180, thereby reducing turbulence and impact noise.

[0068] The connecting port 140 connects the exhaust port 230 to the silencing chamber 150, ensuring that the gas can smoothly enter the silencing chamber 150 for noise reduction. A well-designed connecting port 140 can avoid excessive airflow resistance while ensuring smooth airflow through the entire system.

[0069] By connecting the exhaust port 230 to the muffler 150 instead of directly connecting it to the outside, the noise transmitted directly from the exhaust port 230 can be effectively reduced, further improving the noise reduction effect.

[0070] Optionally, the choice of sound-absorbing material for the inner wall of the anechoic chamber 150 is crucial. Common sound-absorbing materials include fiberglass, mineral wool, and polyurethane foam. Different materials have different sound-absorbing properties and applicable scenarios, and the selection must be based on specific needs.

[0071] For example, a separate silencing cavity 150 is provided inside the receiving component 100. The silencing cavity 150 is located on one side of the mounting cavity 130 and is connected to the inlet of the endoscope through an outlet 180.

[0072] like Figure 2 As shown, in some embodiments, the connecting port 140 and the outlet 180 are located at opposite ends of the silencing cavity 150 to increase the gas flow path between them. For example, the connecting port 140 is located at the bottom of the silencing cavity 150, and the outlet 180 is located at the top of the silencing cavity 150. A violently moving, unstable pulsed airflow enters from the top of the silencing cavity 150 and is buffered. After being blocked by the walls of the silencing cavity 150, the airflow becomes stable by the time it reaches the bottom of the silencing cavity 150, significantly reducing noise. The exhaust port 230 then discharges a stable flow of air.

[0073] like Figure 1As shown, in some embodiments, the housing component 100 is a box, and the air pump cover 110 is installed on the top of the mounting cavity 130. Since the mounting cavity 130 has relatively high noise, the air pump cover 110 and the box are soundproofed and sealed by a sealing ring made of elastic material such as silicone rubber. Similarly, the airtight cover 120 is installed on the top of the silencing cavity 150 and the airflow is sealed by adhesive or other methods.

[0074] like Figure 2 As shown, in some embodiments, the air pump assembly 200 also has a hose 210, and the exhaust port 230 is connected to the communication port 140 through the hose 210;

[0075] The air supply device also includes a damping component 300, which is connected to the receiving component 100. An air pump component 200 is disposed on the damping component 300, and the damping component 300 is used to absorb the vibration energy generated by the air pump component 200.

[0076] In these embodiments, the air pump assembly 200 is connected to the connection port 140 via a hose 210, and the air delivery device also includes a damping component 300 to absorb the vibration energy generated by the air pump assembly 200. This can further optimize airflow management, reduce noise, and minimize the impact of vibration on the overall system.

[0077] Using a flexible hose 210 to connect the exhaust port 230 to the connection port 140 provides a flexible connection method, avoiding stress concentration and potential damage risks caused by rigid connections.

[0078] The hose 210 has a certain degree of flexibility and elasticity, which can isolate the vibration generated by the air pump assembly 200 to a certain extent, preventing these vibrations from being transmitted to the housing assembly 100 or other parts through rigid connections, thereby reducing the vibration and noise of the overall system. The hose 210 connection method is generally more flexible, easy to install and disassemble, and convenient for daily maintenance and repair work.

[0079] The damping component 300 is installed between the air pump assembly 200 and the housing assembly 100, and can effectively absorb the vibration energy generated during the operation of the air pump, reducing the transmission of vibration to the external environment. For example, the damping component 300 can be a rubber pad, spring, or shock absorber, etc.

[0080] Furthermore, reducing vibration not only helps lower noise levels but also improves the overall mechanical stability of the system and extends the equipment's lifespan. Vibration can damage internal precision components, especially during prolonged operation. The vibration damping assembly 300 effectively protects these components, ensuring their long-term stable operation.

[0081] For example, multiple rubber damping pads are installed at the bottom of the air pump assembly 200, with each pad evenly distributed at the four corners or edges of the air pump assembly 200. These damping pads can effectively absorb vertical and horizontal vibrations generated during air pump operation. Additionally, a layer of polyurethane foam pad can be added between the air pump assembly 200 and the housing assembly 100 to further enhance the vibration absorption effect.

[0082] like Figure 2 As shown, in some embodiments, the air pump assembly 200 has a connecting cable, the receiving assembly 100 has a cable port 160, the cable port 160 and the mounting cavity 130 are connected, the connecting cable passes through the cable port 160, and the cable port 160 is provided with a sealing structure for sealing the cable port 160.

[0083] In these embodiments, the air pump assembly 200 has a connecting cable, and the receiving assembly 100 is provided with a cable port 160, which communicates with the mounting cavity 130. The connecting cable passes through the cable port 160 into the mounting cavity 130, and the cable port 160 is provided with a sealing structure to ensure airtightness. This design not only ensures the safety and reliability of the electrical connection, but also effectively prevents external dust, moisture, etc. from entering the mounting cavity 130, thereby protecting the internal components.

[0084] The connecting cables are used to provide power and signal transmission to the air pump assembly 200. Ensuring the reliability and stability of the electrical connections is crucial for the normal operation of the equipment. The connecting cables need to have a certain level of protection, especially in medical environments, where it is particularly important to prevent the influence of external environmental factors (such as humidity and dust) on the electrical system.

[0085] Cable port 160 is the channel for connecting cables to and from the mounting cavity 130. Frictional damage to the cables should be minimized, and smooth cable passage should be ensured. A sealing structure is used to seal the cable port 160, preventing external dust, moisture, etc., from entering the mounting cavity 130. Common sealing structures include rubber gaskets, sealant, or other elastic materials.

[0086] For example, a rubber washer is installed at cable port 160, with the inner diameter of the washer slightly smaller than the cable diameter to ensure a tight fit. A compression sealing device (such as a threaded clamping device) is used to press the rubber washer between the cable and cable port 160 by tightening the nut, forming an effective seal. A layer of sealant can be applied around cable port 160 to further enhance the sealing effect.

[0087] like Figure 2 As shown, in some embodiments, the shock-absorbing assembly 300 includes a base 320 and a foot pad 310, the foot pad 310 being elastic, the base 320 being detachably connected to the receiving assembly 100, and the base 320 also being connected to the air pump assembly 200 via the foot pad 310.

[0088] In these embodiments, the vibration damping assembly 300 includes a base 320 and foot pads 310, the foot pads 310 being elastic. The base 320 is detachably connected to the housing assembly 100, and the base 320 is connected to the air pump assembly 200 via the foot pads 310. This effectively absorbs and isolates vibrations, protects internal components of the equipment, and improves the stability and reliability of the system.

[0089] The base 320 is the foundation of the entire damping assembly 300 and is typically used to support and secure other components. The base 320 is designed to ensure that it can be securely mounted on the housing assembly 100 and has sufficient strength to withstand the weight of the air pump assembly 200 and the dynamic loads during operation.

[0090] Foot pads 310 are resilient components, typically made of rubber, polyurethane foam, or other highly elastic materials. The primary function of foot pads 310 is to absorb and isolate vibrations, reducing the transmission of vibrations generated by the air pump assembly 200 to the base 320 and housing assembly 100.

[0091] The detachable connection between the base 320 and the housing component 100 facilitates maintenance and repair. Detachable connection methods include bolted connections or snap-fit ​​connections.

[0092] The base 320 is connected to the air pump assembly 200 via foot pads 310. The elastic properties of the foot pads 310 can effectively absorb vibrations during air pump operation, reducing the impact on the overall system.

[0093] The base 320 is made of metal (such as aluminum alloy or stainless steel) or high-strength engineering plastic to ensure sufficient rigidity and durability.

[0094] The choice of material for the foot pad 310 is crucial. Examples of foot pad 310 materials include rubber, polyurethane foam, silicone, etc. These materials have good elasticity and vibration-absorbing properties, effectively isolating vibrations.

[0095] In some embodiments, this application also provides an endoscope processor that includes an air delivery device as described in any of the above embodiments.

[0096] Since the aforementioned air supply device has the aforementioned technical effects, the endoscope processor including the air supply device should have the same technical effects, which will not be elaborated here.

[0097] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0098] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0099] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
