Description

Technical Field

[0001] The present disclosure relates to a suction system, an air path module, and a suction system with a heat dissipation function. Background Art

[0002] The suction system can be used to suction and remove tissues, waste fluids, etc. generated during surgery.

[0003] Currently, medical suction systems generally use diaphragm pumps as suction pumps. These are positive displacement pumps that utilize a flexible diaphragm to transfer liquids or gases. The diaphragm pump operates by creating a vacuum within the pump chamber through the reciprocating motion of the diaphragm, drawing the medium in. The diaphragm then expel the medium through the reverse motion of the diaphragm.

[0004] Existing diaphragm pumps generate noise and vibration during operation, which can be disturbing to doctors and patients and even affect the smooth progress of surgery. There is an urgent need to structurally transform the existing suction system.

[0005] In addition, the air inlet and outlet pipes of each air chamber of the diaphragm pump are usually connected together by hoses. There are many hoses, which are particularly tangled. The hoses are exposed to the outside for a long time, and the diaphragm pump is easily cut during transportation.

[0006] Diaphragm pumps generate heat during operation. In existing solutions, each diaphragm pump typically dissipates heat naturally. However, if a diaphragm pump operates continuously for extended periods, it can easily generate excessive heat, impacting its efficiency and stability. Summary of the Invention

[0092] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only intended to explain the relevant content and are not intended to limit the present disclosure. It should also be noted that, for ease of description, only the portions relevant to the present disclosure are shown in the accompanying drawings.

[0093] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0094] Unless otherwise stated, the exemplary embodiments / examples shown are to be understood as providing exemplary features of various details of some ways in which the technical concepts of the present disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of the various embodiments / examples may be further combined, separated, interchanged, and / or rearranged without departing from the technical concepts of the present disclosure.

[0095] The use of cross hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise indicated, the presence or absence of cross hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments can be implemented differently, the specific process sequence can be performed in a different order than described. For example, two successively described processes can be performed substantially simultaneously or in an order opposite to the order described. In addition, the same figure numbers represent the same components.

[0096] When a component is referred to as being “on,” “over,” “connected to,” or “coupled to” another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being “directly on,” “directly connected to,” or “directly coupled to” another component, there are no intervening components present. For this purpose, the term “connected” may refer to a physical connection, an electrical connection, etc., with or without intervening components.

[0097] For descriptive purposes, the present disclosure may use spatially relative terms such as "below," "beneath," "under," "down," "above," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the drawings is turned over, a component described as "below" or "beneath" another component or feature would then be positioned "above" the other component or feature. Thus, the exemplary term "below" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and as such, the spatially relative descriptors used herein should be interpreted accordingly.

[0098] The terms used herein are for the purpose of describing specific embodiments and are not intended to be restrictive. As used herein, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, the features, integral bodies, steps, operations, parts, assemblies and / or their groups stated are explained, but the presence or addition of one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups is not excluded. It should also be noted that, as used herein, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values and / or the values provided that will be recognized by those of ordinary skill in the art.

[0099] Considering that the inlet and outlet pipes of existing diaphragm suction pumps are connected by external hoses, the corresponding external hose connections are complex. Moreover, during the operation of the diaphragm pump, the gas flowing through the air path generates significant vibration and noise. During the operation of the diaphragm pump, the heat generated is often dissipated naturally by the diaphragm pump, which is inefficient and can even affect the diaphragm pump's performance. For example, overheating of the diaphragm pump can cause fluctuations in the diaphragm pump's output pressure.

[0100] To this end, the present disclosure redesigns the structure of a suction system including a diaphragm pump and provides a new suction system.

[0101] Figure 1 This is a schematic diagram of the structure of an attraction system according to an embodiment of the present disclosure. Figure 1As shown, the suction system includes: a diaphragm pump 2, including a diaphragm pump air inlet 24 and a diaphragm pump air outlet 25; an air circuit module 1, including an air circuit module housing 10, an air inlet pipe 11 and an air outlet pipe 12 fixedly arranged in the air circuit module housing 10, the air inlet pipe 11 extends to the first surface of the air circuit module housing 10 and forms a first air port 111, the air outlet pipe 12 extends to the first surface of the air circuit module housing 10 and forms a second air port 121, the first air port 111 is connected to the diaphragm pump air inlet 24, and the second air port 121 is connected to the diaphragm pump air outlet 25; a support part 3, at least a part of the support part 3 is made of flexible material, the support part 3 is arranged between the diaphragm pump 2 and the air circuit module housing 10, the first end of the support part 3 is fixed to the first surface of the air circuit module housing 10, and the second end of the support part 3 is fixed to the diaphragm pump 2.

[0102] like Figure 1 and Figure 3 As shown, in the suction system, the diaphragm pump 2 includes at least one diaphragm pump unit. In addition, a diaphragm pump air inlet 24 and a diaphragm pump air outlet 25 are provided in the diaphragm pump unit. The gas in the diaphragm pump unit will flow through the air inlet pipe 11 and / or the air outlet pipe 12 in sequence. It should be noted that the number of diaphragm pump units of the diaphragm pump 2 can be selected according to the actual needs of the user. The selection of a diaphragm pump with four diaphragm pump units here is only for illustration and does not constitute a limitation to the disclosed solution.

[0103] In the disclosed solution, each of the inlet and outlet pipes connected to the diaphragm pump 2 is enclosed in a single air module housing 10. Specifically, the inlet and outlet pipes 11, 12 are enclosed in the same air module housing 10. This allows the noise and vibration of gas flowing through the inlet and outlet pipes 11, 12 to be isolated within the air module housing 10. In other words, by enclosing the inlet and outlet pipes 11, 12 within the air module housing 10, the noise generated by the diaphragm pump 2 during operation can be effectively reduced.

[0104] In addition, a support portion 3 (including a first support portion 31 and a second support portion 32) is provided between the diaphragm pump 2 and the air circuit module housing 10. The support portion 3 is made of a flexible material. For example, it can be a flexible silicone tube, or the middle section of the support portion 3 is made of silicone material, while the ends of the support portion 3 are made of a solid hard material. The reason for using a flexible material to make the support portion 3 here is that the flexible material can effectively filter out the vibration and noise generated by the diaphragm pump 2 during operation, preventing the diaphragm pump 2 from transmitting the vibration and noise to the air circuit module 1.

[0105] On the basis of using the gas path module housing 10 to encapsulate the inlet pipe 11 and the outlet pipe 12, the first surface (that is, Figure 2A first air port 111 and a second air port 121 are formed on the upper surface of the air module housing 10. The air inlet pipe 11 in the air module housing 10 extends to the first surface of the air module housing 10 and communicates with the first air port 111 formed on the first surface. At the same time, the air outlet pipe 12 in the air module housing 10 extends to the first surface of the air module housing 10 and communicates with the second air port 121 formed on the first surface.

[0106] As described above, since the air inlet pipe 11 and the air outlet pipe 12 are both enclosed in the air module housing 10, the noise and air pipe vibration generated when the gas flows through the air inlet pipe and the air outlet pipe are isolated in the air module housing 10. This can reduce the overall operating noise of the air module 1.

[0107] The structural relationship of the support parts will be described below through a specific embodiment. In one optional embodiment, there are multiple support parts 3, each including at least one first support part 31 and at least one second support part 32. The first air port 111 communicates with the diaphragm pump air inlet 24 via the first support part 31; the second air port 121 communicates with the diaphragm pump air outlet 25 via the second support part 32. Both the first support part 31 and the second support part 32 are flexible tubes that provide support functions.

[0108] Specifically, in addition to supporting the diaphragm pump 2 above the air circuit module 1, the support portion 3 also has the function of connecting the diaphragm pump 2 and the air circuit module 1 for ventilation. The support portion 3 can be a flexible silicone tube with supporting capabilities, so that the support portion 3 can meet both support and ventilation requirements. Of course, the support portion 3 can also be a flexible pipe made of other materials, such as a pipe made of rubber or plastic, which meets the support and ventilation requirements and can prevent vibration and noise from being transmitted from the diaphragm pump 2 to the air circuit module 1. Taking the connection of a diaphragm pump unit in the diaphragm pump 2 as an example, it includes a diaphragm pump air inlet 24 and a diaphragm pump air outlet 25. Among them, the first end of the first support portion 31 is connected to the first air port 111, and the second end of the first support portion 32 is connected to the diaphragm pump air inlet 24; the first end of the second support portion 32 is connected to the second air port 121, and the second end of the second support portion 32 is connected to the diaphragm pump air outlet 25.

[0109] Through the disclosed solution, the air path module 1 and the diaphragm pump 2 are constructed into a complete suction system using the support portion 3. The support portion 3 has both support and ventilation functions. Furthermore, because the support portion 3 is made of a flexible material, both the vibration and noise of the diaphragm pump 3 and the vibration and noise generated by the gas flow can be filtered out or partially filtered out by the support portion 3, effectively reducing the noise and vibration transmitted outward during the operation of the suction system.

[0110] In addition, the present disclosure also provides another optional solution. There are multiple support portions 3, each including at least one first support portion 31 and at least one second support portion 32. Both the first support portion 31 and the second support portion 32 are hollow structures. A first flexible tube is passed through the hollow structure of the first support portion 31, and a second flexible tube is passed through the hollow structure of the second support portion 32. The first air port 111 communicates with the diaphragm pump air inlet 24 via the first flexible tube. The second air port 121 communicates with the diaphragm pump air outlet 25 via the second flexible tube.

[0111] In the disclosed solution, support portion 3 can be a hollow structure of any shape. That is, support portion 3 is a hollow flexible structure, and the inner diameter of the hollow space must be larger than the outer diameter of the flexible tube to ensure that the flexible tube can smoothly pass through support portion 3. In the disclosed solution, the function of support portion 3 is to support diaphragm pump 2 above gas circuit module 1 and prevent or reduce the transmission of vibration and noise generated by diaphragm pump 2 during operation to gas circuit module 1. At the same time, the flexible tube connecting diaphragm pump 2 and gas circuit module 1 is also made of a flexible material to transmit gas while reducing or minimizing the transmission of vibration and noise.

[0112] Specifically, the first support portion 31 and the second support portion 32 are disposed between the air circuit module 1 and the diaphragm pump 2. After the first flexible tube is placed within the first support portion 31, the first end of the first flexible tube is connected to the first air port 111, and the second end of the first flexible tube is connected to the diaphragm pump air inlet 24. After the second flexible tube is placed within the second support portion 32, the first end of the second flexible tube is connected to the second air port 121, and the second end of the second flexible tube is connected to the diaphragm pump air outlet 25. Thus, it can be seen that this combination of the flexible tube and the support portion 3 not only ensures stable support of the diaphragm pump 2 by the air circuit module 1, but also meets the ventilation requirements of the diaphragm pump 2 and the air circuit module 1.

[0113] In one or more embodiments of the present disclosure, the air circuit module housing 10 is in the shape of a rectangular parallelepiped, and a plurality of flexible pads 4 are evenly arranged on the second surface of the air circuit module housing 10, and the suction system can be placed on the support surface based on the plurality of flexible pads 4; the second surface of the air circuit module housing 10 and the first surface of the air circuit module housing 10 are two opposite surfaces of the rectangular parallelepiped.

[0114] like Figure 2 As shown, the gas circuit module housing 10 can be a rectangular parallelepiped housing. It should be noted that this is only an example and does not constitute a limitation to the technical solution disclosed herein. In actual applications, users can also make the gas circuit module housing 10 into a cube, cylinder, or other irregular three-dimensional structure.

[0115] On the second surface of the gas path module housing 10 (that is, Figure 2A plurality of flexible feet 4 are provided on the bottom surface of the rectangular parallelepiped as shown. For example, the plurality of flexible feet 4 can be provided near the four vertex areas of the bottom surface of the rectangular parallelepiped. Five flexible feet 4 can also be provided, respectively near the four vertex areas of the bottom surface and the center point of the bottom surface. Figure 2 As shown, in order to make the flexible foot 4 more firmly installed, a through bolt hole 15 can be opened, and then the flexible foot 4 can be fixed to the second surface by using bolts.

[0116] During the operation of the diaphragm pump 2, some vibration and noise are inevitably transmitted to the air circuit module 1. For example, in an alternative embodiment, the suction system is used as an endoscope power system, and the air circuit module 1 in the suction system can be installed on the bottom surface of the endoscope power system housing. The flexible feet 4 can effectively filter out noise and vibration, thereby reducing or preventing noise and vibration from being transmitted to the supporting surface, effectively reducing the impact of the suction system operation on the user.

[0117] It should be noted here that the first surface and the second surface mentioned above represent the top surface and the bottom surface of the gas path module housing 10 respectively, and the first surface and the second surface are parallel to each other.

[0118] The extension direction of the support portion 3 is perpendicular to the first surface of the gas path module housing 10 , that is, the support portion 3 is installed on the first surface, and when installed, the support portion 3 maintains a perpendicular relationship with both the first surface and the second surface.

[0119] In one or more embodiments of the present disclosure, the extension direction of the air inlet pipe 11 in the air path module shell 10 is parallel to the first surface, and the extension direction of the air outlet pipe 12 in the air path module shell 10 is parallel to the first surface; sound-absorbing materials are filled between the air inlet pipe 11 and the inner wall of the air path module shell 10, between the air outlet pipe 12 and the inner wall of the air path module shell 10, and between the air inlet pipe 11 and the air outlet pipe 12.

[0120] To prevent interference between the inlet and outlet pipes 11, 12 within the air module housing 10 (e.g., interference during layout within the housing, or noise caused by friction between the inlet and outlet pipes due to vibration), the inlet pipe 11 is arranged parallel to the first surface (or second surface). Simultaneously, the outlet pipe 12 is arranged parallel to the first surface (or second surface). This ensures that the inlet and outlet pipes 11, 12 are parallel to each other.

[0121] To further enhance the quietness of the air path module 1, sound-absorbing material may be placed in various locations. Specifically, the sound-absorbing material may be placed between the air intake pipe 11 and the air path module housing 10. For example, the sound-absorbing material may be adhered to the inner wall of the housing (i.e., the air path module housing 10) and wrapped around the outer wall of the air intake pipe 11. Sound-absorbing material may also be adhered to both the inner wall of the housing and the outer wall of the air intake pipe 11.

[0122] You can also fill the space between the air outlet pipe 12 and the air path module shell 10 with sound-absorbing material, adhere the sound-absorbing material to the inner wall of the shell, wrap the sound-absorbing material around the outer wall of the air outlet pipe 12, or adhere the sound-absorbing material to both the inner wall of the shell and the outer wall of the air outlet pipe 12 at the same time.

[0123] A sound-absorbing material may also be filled between the air inlet pipe 11 and the air outlet pipe 12. For example, the sound-absorbing material may be wrapped around the outer wall of the air inlet pipe 11 and the outer wall of the air outlet pipe 12.

[0124] It should be noted that the sound-absorbing materials mentioned here may be, for example, polyester fiber sound insulation cotton, rock wool, glass wool, foam sound insulation cotton, mineral wool, etc.

[0125] Based on the above-disclosed solution, it can be seen that by adding silent materials to the air module housing 10, the quieting and vibration-reducing effects of the air module 1 can be further enhanced. Specifically, by encapsulating both the inlet and outlet pipes 11, 12 within the air module 1, the air module housing 10 can effectively reduce the noise and vibration transmitted from the inlet and outlet pipes 11, 12 to the outside world. Furthermore, adding silent materials to the air module housing 10 can further enhance the vibration and noise reduction effects of the air module 1.

[0126] In one or more embodiments of the present disclosure, the extension direction of the air inlet pipe 11 in the air path module shell 10 is parallel to the first surface, and the extension direction of the air outlet pipe 12 in the air path module shell 10 is parallel to the first surface; injection molding is performed between the air inlet pipe 11 and the inner wall of the air path module shell 10, between the air outlet pipe 12 and the inner wall of the air path module shell 10, and between the air inlet pipe 11 and the air outlet pipe 12, so that the air path module shell 10 and the air inlet pipe 11 and the air outlet pipe 12 form an integrated structure.

[0127] In an optional solution, the air circuit module 1 can also be made by injection molding. When casting, the air inlet pipe 11 and the air outlet pipe 12 that are interconnected can be cast inside the entity as needed. Of course, the air inlet pipe 11 and the air outlet pipe 12 can also be drilled out as needed. There is no need to lay additional air inlet pipes 11 or air outlet pipes 12, which can simplify the overall structure of the air circuit module 1. Moreover, the air circuit module housing 10 of this solid structure has a better sound insulation effect. In addition, since there is no need to add independent air inlet pipes 11 and air outlet pipes 12 to the air circuit module 1, the noise caused by the mutual friction caused by the vibration of the air inlet pipe 11 and the air outlet pipe 12 can be effectively avoided.

[0128] In one or more embodiments of the present disclosure, a plurality of first through holes 171 and a plurality of second through holes 172 are provided on the side wall of the air circuit module housing 10; the air inlet pipe 11 includes a plurality of pipe air inlet ends, each of which is connected to a first through hole 171, and the first through hole 171 radially supports the pipe air inlet end; the air outlet pipe 12 includes a plurality of pipe air outlet ends, each of which is connected to a second through hole 172, and the second through hole 172 radially supports the pipe air outlet end.

[0129] like Figure 2 As shown, on the side wall of the gas circuit module housing 10 (for example, Figure 2 There are multiple through holes on the front, back, left and right side walls of the rectangular parallelepiped shown in FIG. For the convenience of distinction, the through hole for connecting the air inlet pipe 11 can be called the first through hole, and the through hole for connecting the air outlet pipe 12 can be called the second through hole. Figure 1 As can be seen in the figure, there are multiple first through holes 171 and multiple second through holes 172 on the side.

[0130] After the air inlet end of the air inlet pipe 11 passes through the first through hole 171 , it is fixedly mounted on the first through hole 171 through the sealing plug 17 , so that the first through hole can play a supporting role in the radial direction of the air inlet end of the pipe.

[0131] After the gas outlet end of the gas outlet pipe 12 passes through the second through hole 172 , it is fixedly mounted on the second through hole 172 through the sealing plug 17 , so that the second through hole 172 can play a supporting role in the radial direction of the gas outlet end of the pipe.

[0132] Based on the disclosed solution, it can be seen that the inlet and outlet pipes 11, 12 are radially supported by the first and second through holes, allowing them to be more stably fixed to the air module housing 10, effectively preventing or reducing the vibration amplitude of the inlet and outlet pipes 11, 12 within the housing. This can further reduce the noise and vibration generated during the operation of the suction system.

[0133] In one or more embodiments of the present disclosure, the first through hole 171 and the second through hole 172 can be blocked by the sealing plug 17, so that air can enter through one or more unblocked first through holes and exhaust through one or more unblocked second through holes.

[0134] In actual use, after the air inlet end of the air inlet pipe 11 passes through the first through hole 171, the ports of the air inlet pipe 11 will be exposed to the outside. However, during use, only one of the ports may be used as the air inlet, and the other ports can be sealed with the sealing plug 17. When it is necessary to replace the port or open more ports later, the blocked port can be opened.

[0135] When the outlet end of the outlet pipe 12 passes through the second through hole, the ports of the outlet pipe 12 are exposed to the outside. However, during use, only one of the ports may be used as an outlet, and the other ports can be sealed with the sealing plug 17. When it is necessary to replace the port or open more ports later, the blocked port can be opened.

[0136] Through the above method, not only can the air inlet pipe 11 and the air outlet pipe 12 be more stably fixed in the air path module 1, but the ventilation port can also be selectively opened as needed to better meet the diverse usage needs of users.

[0137] In one or more embodiments of the present disclosure, the inner diameter of the first support portion 31 is interference fit with the first air port 111 and the diaphragm pump air inlet 24 respectively; the inner diameter of the second support portion 32 is interference fit with the second air port 121 and the diaphragm pump air outlet 25 respectively.

[0138] As mentioned above and Figure 1 As shown, when connecting the first air port 111 and the diaphragm pump air inlet 24 via the first support portion 31, the first air port 111 is inserted into one end of the first support portion 31, while the diaphragm pump air inlet 24 is inserted into the other end of the first support portion 31. To ensure a more stable connection between the two ends of the first support portion 31, the inner diameter of the first support portion 31 needs to be able to have an interference fit with the first air port 111 and the diaphragm pump air inlet 24. In other words, the connection between the first support portion 31, the first air port 111, and the diaphragm pump air inlet 24 is more stable and secure. This prevents mutual vibration and friction between the first support portion 31, the first air port 111, and the diaphragm pump air inlet 24.

[0139] When using the second support portion 32 to connect the second air port 121 and the diaphragm pump outlet 25, the second air port 121 is inserted into one end of the second support portion 32, while the diaphragm pump outlet 25 is inserted into the other end of the second support portion 32. To ensure a stable connection between the two ends of the second support portion 32, the inner diameter of the second support portion 32 needs to be able to provide an interference fit with the second air port 121 and the diaphragm pump outlet 25. This ensures a more stable and secure connection between the second support portion 32, the second air port 121, and the diaphragm pump outlet 25. This prevents vibration and friction between the second support portion 32, the second air port 121, and the diaphragm pump outlet 25.

[0140] This interference fit connection makes the connection between the first support portion 31, the first air port 111, and the diaphragm pump air inlet 24 more secure and stable, preventing excessive vibration or shaking during ventilation. It also makes the connection between the second support portion 32, the second air port 111, and the diaphragm pump air outlet 25 more secure and stable.

[0141] In one or more embodiments of the present disclosure, there are multiple support portions 3 , each support portion 3 is spaced apart, and the multiple support portions 3 are evenly arranged in the edge region of the first surface.

[0142] In actual applications, when the diaphragm pump 2 has multiple diaphragm pump units 26, the diaphragm pump 2 needs to have multiple support parts 3 to support the diaphragm pump 2 and connect the diaphragm pump 2 with the air path module 1. When the diaphragm pump 2 is working, vibration will be generated. Accordingly, the support part 3 connected to the diaphragm pump 2 will also be affected by the vibration and vibrate along with it. In order to avoid friction between the support parts 3 when they vibrate, it is necessary to ensure that a certain distance is maintained between the two adjacent support parts 3. Generally speaking, it is necessary to ensure that the distance is significantly larger than the vibration amplitude of the support part 3.

[0143] In an optional solution, the plurality of support portions 3 may be evenly arranged in the edge region of the first surface. For example, four groups of support portions 3 may be respectively arranged near the four vertex regions of the first surface.

[0144] Based on the above disclosed solution, it can be seen that by evenly disposing the plurality of support portions 3 at the edge of the first surface and ensuring a certain spacing between two adjacent support portions 3, friction between the two adjacent support portions 3 can be avoided when the diaphragm pump 2 is in operation, further contributing to an improved quieting effect.

[0145] In one or more embodiments of the present disclosure, there is one support portion 3 , which is disposed in the middle region of the first surface, and the cross-sectional area of the first end portion is at least half of the area of the first surface.

[0146] In practical applications, there may be only one supporting portion 3. This supporting portion 3 may be a relatively large supporting portion 3, and the diaphragm pump 2 can be supported above the first surface by using only one supporting portion 3.

[0147] In order to enable the support part 3 to stably support the diaphragm pump 2 above the air path module 1, the support part 3 can be set in the middle area of the first surface, that is, when the diaphragm pump 2 and the air path module 1 are aligned in the vertical center, the support part 3 can be supported at the center position of the diaphragm pump 2, thereby making the diaphragm pump 2 more stable.

[0148] Furthermore, the cross-sectional area of the support portion 3 can be increased. For example, the cross-sectional area of the support portion 3 can be increased to one-half the area of the first surface. It should be noted that the one-half mentioned here is merely an example; in actual applications, the cross-sectional area can be increased to any desired size, such as one-third or three-quarters. Generally speaking, the larger the increased cross-sectional area, the better the support stability of the support portion 3.

[0149] In addition, the present disclosure redesigns the structure of the diaphragm suction pump and provides a new air path module.

[0150] Figure 2 This is a schematic diagram of the structure of the gas circuit module according to an embodiment of the present disclosure. Figure 2 As can be seen in the figure, the air circuit module 1 includes an air circuit module housing 10; and an air inlet pipe 11 and an air outlet pipe 12 fixedly arranged inside the air circuit module housing 10. The air inlet pipe 11 is connected to a first air port 111 arranged on the first surface of the air circuit module housing 10, and the air outlet pipe 12 is connected to a second air port 121 arranged on the first surface of the air circuit module housing 10. The extension direction of the air inlet pipe 11 in the air circuit module housing 10 and the extension direction of the air outlet pipe 12 in the air circuit module housing 10 are both parallel to the first surface. A first through hole 171 and a second through hole 172 are provided on the side wall of the air circuit module housing 10. The air inlet pipe 11 includes a pipe air inlet end, which is connected to the first through hole 171, and the air outlet pipe 12 includes a pipe air outlet end, which is connected to the second through hole 172.

[0151] from Figure 2 and Figure 1 It can be seen that in the disclosed solution, the gas circuit module 1 includes a gas circuit module housing 10, and the gas circuit module housing 10 encapsulates an air inlet pipe 11 and an air outlet pipe 12. Specifically, on the first surface (i.e. Figure 2 Gas ports are provided on the top surface of the rectangle as shown, namely a first gas port 111 and a second gas port 121.

[0152] The air inlet pipe 11 is connected to the first air port 111, and the air outlet pipe 12 is connected to the second air port 121. The air inlet pipe 11 and the air outlet pipe 12 extend in the air path module housing 10. To ensure that the pipes do not affect each other during extension, the air inlet pipe 11 and the air outlet pipe 12 can be extended in a direction parallel to the first surface.

[0153] In addition, a first through hole 171 and a second through hole 172 are formed on the side wall of the air module housing 10 . The air inlet end of the air inlet pipe 11 is connected to the first through hole 171 , and the air outlet end of the air outlet pipe 12 is connected to the second through hole 172 .

[0154] It can be seen that the air inlet pipe 11 and the air outlet pipe 12 are encapsulated as a whole in the air path module shell 10, making the air path of the diaphragm suction pump more regular, and the air path module shell 10 can provide good protection for the air inlet pipe 11 and the air outlet pipe 12 to prevent them from being scratched.

[0155] In addition, the air circuit module housing 10 also supports the diaphragm pump 2 , so that the diaphragm pump 2 and the air circuit module housing 10 can form a complete suction system.

[0156] In one or more embodiments of the present disclosure, the number of the first through holes 171 and the number of the second through holes 172 are both one; the first through holes 171 and the second through holes 172 are opened on the same side wall of the air path module housing 10; or, the first through holes 171 and the second through holes 172 are opened on two different side walls of the air path module housing 10.

[0157] In an alternative embodiment, a first through hole 171 and a second through hole 172 may be respectively provided on the side wall of the gas circuit module housing 10. Specifically, the first through hole 171 and the second through hole 172 may be provided simultaneously on the side wall of the gas circuit module housing 10 on the same side. Of course, the first through hole 171 and the second through hole 172 may also be provided on different side walls of the gas circuit module housing 10, for example, on two opposing side walls, or on two adjacent side walls.

[0158] When actually opening the through holes, the positional relationship between the air inlet pipe 11 and the air outlet pipe 12 in the air path module 1 must be considered to ensure that the two through holes opened and the two pipes connected to the two through holes do not interfere with each other.

[0159] In one or more embodiments of the present disclosure, the number of the first through holes 171 and the number of the second through holes 172 are both multiple, and the number of the first through holes 171 and the number of the second through holes 172 are equal or unequal; at least two first through holes 171 are formed on different side walls of the air path module housing 10; and at least two second through holes 172 are formed on different side walls of the air path module housing 10.

[0160] In practical applications, the number of the first through hole 171 and the second through hole 172 can be multiple. Specifically, there can be at least two first through holes 171, and these first through holes 171 can be respectively arranged on different side walls of the gas circuit module housing 10. For example, one first through hole 171 is arranged on the first side wall (for example, Figure 2 The front side wall of the rectangular parallelepiped shown in FIG. 1 ), another first through hole 171 is provided on the second side wall (eg, Figure 2 (The rear side wall of the rectangular parallelepiped shown). Figure 2 As can be seen in the figure, the first side wall and the second side wall are two different side walls parallel to each other.

[0161] In addition, the number of second through holes 172 may be at least two. Furthermore, the plurality of second through holes 172 may be respectively disposed on different side walls of the air path module housing 10. For example, one second through hole 172 may be disposed on the first side wall, while another second through hole 172 may be disposed on the second side wall.

[0162] It should be noted that there is no limit to the number of first through holes 171 and the number of second through holes 172. If more through holes are required, they can be arranged on appropriate sidewalls as needed. Moreover, the number of first through holes 171 and the number of second through holes 172 can be equal or unequal. The specific number can be selected based on actual application requirements.

[0163] Based on the above disclosed solution, the number of through holes can be set as needed, and the side walls where the first through hole 171 and the second through hole 172 are located can also be selected as needed, thereby meeting the diverse usage needs of users.

[0164] In one or more embodiments of the present disclosure, the air intake pipe 11 includes an air intake main pipe 112, and the air outlet pipe 12 includes an air outlet main pipe 122; the two ends of the air intake main pipe 112 are respectively connected to a first through hole 171; the two ends of the air outlet main pipe 122 are respectively connected to a second through hole 172.

[0165] In practical applications, such as Figure 2As shown, the air inlet pipe 11 includes an air inlet main pipe 112, and the air outlet pipe 12 includes an air outlet main pipe 122. Both ends of the air inlet main pipe 112 (that is, the two air inlet ends of the pipes) are respectively connected to the first through hole 171, as shown in FIG. Figure 2 As shown, first through holes 171 are respectively opened on two opposite side walls, and the two air inlet ends of the main air inlet line 112 are respectively communicated with the first through holes 171 .

[0166] The two ends of the main gas outlet pipe 122 (that is, the two gas outlet ends of the pipe) are respectively connected to the second through hole 172. Figure 1 As shown, two opposite side walls are respectively provided with second through holes 172 , and the two gas outlet ends of the main gas outlet line 122 are respectively communicated with the second through holes 172 .

[0167] Based on the disclosed solution, the main inlet and outlet pipes 112 and 122 are fixedly connected to the through-holes of the air module housing 10, respectively, so that the inlet and outlet pipes 11 and 12 can be more stably fixed within the housing. When air flows through the inlet and outlet pipes 11 and 12, it can prevent large vibrations in the pipes and reduce vibration noise during airflow.

[0168] In one or more embodiments of the present disclosure, the intake pipe 11 further includes at least one intake branch pipe 113 , one end of which is connected to the intake main pipe 112 , and the other end of which is connected to a first through hole 171 .

[0169] In practical applications, an intake branch line 113 may be extended from the intake main line 112. Figure 2 As shown, one end of the air intake branch line 113 is used to connect with the air intake main line 112, and the other end of the air intake branch line 113 is connected with the first through hole 171 as the pipeline air intake end, so as to provide more pipeline air intake ends to the outside to meet diversified usage needs (for example, the need to connect multiple air inlets).

[0170] The number of the specific intake branch pipes 113 is not limited and can be selected and set according to actual application requirements. However, it should be noted that it is necessary to ensure that the intake branch pipes 113 can be encapsulated in the housing.

[0171] In one or more embodiments of the present disclosure, the gas outlet pipeline 12 further includes at least one gas outlet branch pipeline 123 , one end of which is connected to the gas outlet main pipeline 122 , and the other end of which is connected to a second through hole 172 .

[0172] In practical applications, an outlet branch line 123 may be extended from the outlet main line 122. Figure 2As shown, one end of the outlet branch pipe 123 is used to connect with the outlet main pipe 122, and the other end of the outlet branch pipe 123 is connected with the second through hole 172 as the pipe outlet end, thereby providing more pipe outlet ends to the outside to meet diversified usage needs (for example, multiple outlets need to be connected).

[0173] There is no specific limit on the number of the outlet branch pipes 123, and the number can be selected according to actual application requirements. However, it should be noted that it is necessary to ensure that the outlet branch pipes 123 can be encapsulated in the housing.

[0174] In one or more embodiments of the present disclosure, the first through hole 171 and the second through hole 172 can be blocked by the sealing plug 17 , so that air can enter through one or more unblocked first through holes 171 and exit through one or more unblocked second through holes 172 .

[0175] As previously mentioned, the ends of the main intake line 112 and the branch intake line 113 are both connected to the first through-holes 171. However, in actual applications, not every through-hole is used. Therefore, the sealing plugs 17 can be used to block the first through-holes 171 that are not currently in use, leaving only one or more first through-holes 171 that are currently in use.

[0176] Similarly, the ends of the main outlet pipe 122 and the branch outlet pipe 123 are also connected to the second through holes 172. However, in actual applications, not every second through hole 172 for outlet is used. Therefore, the sealing plug 17 can be used to block the second through holes 172 that are not currently in use, leaving only one or more second through holes 172 that are currently in use.

[0177] Based on the above disclosed solution, the through-holes can be selectively blocked or opened as needed, thereby better meeting the user's diverse needs for using the suction pump system.

[0178] In one or more embodiments of the present disclosure, at least one sealing plug 17 is replaced by an air pressure sensor 16, the first through hole 171 and / or the second through hole 172 are sealed via the air pressure sensor 16, and the gas pressure in the air inlet pipe 11 and / or the air outlet pipe 12 is measured via the air pressure sensor 16.

[0179] In actual application, in order to facilitate users to understand the working status of the suction pump system in real time, an air pressure sensor 16 can be installed in the first through hole 171 of the air inlet pipe 11 and / or the second through hole 172 of the air outlet pipe 12. The air pressure sensor 16 can collect the current gas pressure in the pipe in real time.

[0180] In an optional solution, air pressure sensors 16 may be installed on both the first through hole 171 and the second through hole 172 , and the average value measured by the two air pressure sensors 16 may be used as the current actual pressure value.

[0181] For example, in surgical applications, a suction pump system can be used to remove blood clots generated inside the cavity of the operated object during the operation, that is, the blood clots are sucked away by the suction pump. At this time, it is necessary to ensure that the suction pump has an appropriate working pressure so that the blood clots can be sucked away without generating excessive air pressure that may damage the operated object. When the air pressure value displayed by the air pressure sensor 16 does not meet the requirements, the air pressure can be changed by adjusting the working state of the diaphragm pump so that the suction system can provide an air pressure value that meets the requirements.

[0182] Based on the above solution, it can be seen that by installing the air pressure sensor 16 in the corresponding through hole, the air pressure in the pipeline can be detected in real time, so that the user can intuitively understand the working status of the suction system.

[0183] In one or more embodiments of the present disclosure, in a direction perpendicular to the first surface, the air inlet pipe 11 and the air outlet pipe 12 have a preset distance.

[0184] In actual use, although the inlet and outlet pipes 11, 12 are arranged parallel to each other in the gas module housing 10, gas flowing through the pipes inevitably causes vibration. If the pipes are closely adjacent, or the spacing between adjacent inlet and outlet pipes 11, 12 is too small, the inlet and outlet pipes 11, 12 will vibrate when the gas flows through the pipes, causing collision or friction between the two adjacent pipes.

[0185] Therefore, the air inlet pipe 11 and the air outlet pipe 12 in the air path module housing 10 can be arranged parallel to the first surface, while ensuring that the air inlet pipe 11 and the air outlet pipe 12 are greater than or equal to the preset distance in the direction perpendicular to the first surface.

[0186] Based on the above-mentioned disclosed solution, when setting the pipeline in the air circuit module shell 10, ensure that a certain preset distance is maintained between the air inlet pipeline 11 and the air outlet pipeline 12, so that even if the air circuit module 1 vibrates during operation, there will be no pipeline collision and friction, making the overall air circuit module 1 quieter.

[0187] In one or more embodiments of the present disclosure, the air inlet pipe 11 is connected to the first air port 111 provided on the first surface of the air path module housing 10 via the first vertical pipe 114, and the air outlet pipe 12 is connected to the second air port 121 provided on the first surface of the air path module housing 10 via the second vertical pipe 124.

[0188] In practical applications, such as Figure 2 As shown, a plurality of air intake branch pipes 113 are connected to the air intake pipe 11, and each air intake branch pipe 113 is vertically connected to a first vertical pipe 114, and the first vertical pipe 114 is connected to the first air port 111 opened on the air circuit module housing 10. The first vertical pipe 114 is perpendicular to the first surface of the air circuit module housing 10. It should be noted that the number of the first vertical pipes 114 and the air intake branch pipes 113 is consistent with the number of the diaphragm pump units, so as to meet the air intake requirements of the diaphragm pump units. Figure 2 and Figure 4 As shown, the first vertical tube 114 extends a certain distance above the first surface and is communicated with the diaphragm pump air inlet 24.

[0189] like Figure 2 As shown, a plurality of outlet branch pipes 123 are connected to the outlet pipe 12, and each outlet branch pipe 123 is vertically connected to a second vertical pipe 124, and the second vertical pipe 124 is connected to the second air port 121 opened on the air circuit module shell 10. The second vertical pipe 124 is perpendicular to the first surface of the air circuit module shell 10. It should be noted that the number of the second vertical pipes 124 and the outlet branch pipes 123 is consistent with the number of the diaphragm pump units, so as to meet the air outlet requirements of the diaphragm pump units. Figure 2 and Figure 4 As shown, the second vertical tube 124 extends a certain distance above the first surface and is communicated with the diaphragm pump air outlet 25.

[0190] Furthermore, the first vertical pipe 114 and the second vertical pipe 124 are parallel to each other. It should be noted that to ensure that the first vertical pipe 114 and the second vertical pipe 124 do not interfere with each other, or to ensure that the outlet pipe 12 does not affect the normal configuration of the first vertical pipe 114 and that the inlet pipe 11 does not affect the normal configuration of the second vertical pipe 124, the outlet pipe 12 and the inlet pipe 11 need to be horizontally parallel and staggered relative to each other.

[0191] Based on the above-mentioned disclosed solution, by respectively arranging a first vertical pipe and a second vertical pipe vertically upward on the air inlet pipe 11 and the air outlet pipe 12, it is possible to connect with the diaphragm pump 2 above the air path module 1, so that the air inlet pipe 11 and the air outlet pipe 12 of the diaphragm pump 2 are both encapsulated in the air path module housing 10.

[0192] In one or more embodiments of the present disclosure, the first vertical pipe and the air inlet pipe 11 are formed into an integrated structure, and the second vertical pipe and the air outlet pipe 12 are formed into an integrated structure.

[0193] like Figure 2 and Figure 1As shown, the first vertical pipe 114 and the air inlet pipe 11 , and the second vertical pipe 124 and the air outlet pipe 12 can be connected in an integral structure, for example, by integral injection molding.

[0194] Of course, the first vertical pipe 114 can also be spliced to the air inlet pipe 11, and the second vertical pipe 124 can be spliced to the air outlet pipe 12 as needed. For example, two sections of the air inlet pipe 11 and the first vertical pipe 114 can be spliced together through a tee joint. Similarly, two sections of the air outlet pipe 12 and the second vertical pipe 124 can also be spliced together through a tee joint.

[0195] In one or more embodiments of the present disclosure, the radial dimension of the first vertical pipe is smaller than the radial dimension of the air inlet pipe 11 , and the radial dimension of the second vertical pipe is smaller than the radial dimension of the air outlet pipe 12 .

[0196] from Figure 2 As can be seen in the figure, the diaphragm pump 2 is provided with multiple diaphragm pump air inlets 24, that is, they need to be connected to multiple first vertical tubes 114, and the multiple first vertical tubes 114 are all connected to the same air inlet pipeline 11. To ensure that the diaphragm pump 2 can smoothly intake air, it is necessary to ensure that the radial dimension of the air inlet pipeline 11 (that is, the diameter of the air inlet pipeline 11) is greater than the radial dimension of the first vertical tubes 114 (that is, the diameter of the first vertical tubes 114).

[0197] In actual applications, the difference in radial dimensions between the first vertical tube 114 and the air inlet pipe 11 can be selected according to the actual needs of the user. Of course, if the air flow speed is relatively fast and the flow volume is relatively large, the radial dimensions of the multiple first vertical tubes can be set to be the same as the air inlet pipe 11, so as to make the overall ventilation efficiency higher. It should be noted that, although theoretically the larger the radial dimensions of the air inlet pipe 11, the first vertical tube, the air outlet pipe 12 and the second vertical tube, the better, it is necessary to take into account the limited internal space of the air path module housing 10. Therefore, when selecting the radial dimensions, it is necessary to avoid the air inlet pipe 11 and the air outlet pipe 12 being closely adjacent or rubbing against each other due to excessive radial dimensions.

[0198] In one or more embodiments of the present disclosure, injection molding is performed between the air inlet pipe and the inner wall of the air path module shell, between the air outlet pipe and the inner wall of the air path module shell, and between the air inlet pipe and the air outlet pipe, so that the air path module shell and the air inlet pipe and the air outlet pipe form an integrated structure.

[0199] In practical applications, the gas circuit module housing 10 can be made of a metal housing, an injection molded housing, etc. The housing can be opened or closed as needed. In order to provide the housing with a better sound insulation effect, the housing can be sealed more tightly.

[0200] In addition, the air circuit module housing 10 can also be a solid (for example, a solid rectangular parallelepiped), and the material of this solid body can be a metal solid or a rubber solid. As needed, the air inlet pipe 11 and the air outlet pipe 12 that are interconnected can be cast inside the solid body during injection molding. Of course, the air inlet pipe 11 and the air outlet pipe 12 can also be drilled out as needed. There is no need to lay additional pipes, which can simplify the overall structure of the diaphragm suction pump. In addition, the air circuit module housing 10 with this solid structure has a better sound insulation effect.

[0201] In one or more embodiments of the present disclosure, sound-absorbing materials are filled between the air inlet pipe and the inner wall of the air path module housing, between the air outlet pipe and the inner wall of the air path module housing, and between the air inlet pipe and the air outlet pipe.

[0202] In practical applications, the air path module housing 10 may be filled with sound insulation cotton, or the sound insulation cotton may be adhered to the inner wall of the air path module housing 10 , so that the sound insulation effect of the air path module housing 10 is better.

[0203] In an optional solution, the outer walls of the air inlet pipe 11 and the air outlet pipe 12 can also be wrapped with a sound-absorbing material (i.e., a layer of sound-insulating cotton material). This isolates the vibrations of the gas flow inside the sound-insulating cotton (i.e., performs primary sound insulation). On this basis, secondary sound insulation is further performed through the air path module housing 10.

[0204] In an optional solution, the air module housing 10 may be filled with sound insulation cotton, the inner wall of the air module housing 10 may be affixed with sound insulation cotton, and the air inlet pipe 11 and the air outlet pipe 12 may be wrapped with sound insulation cotton. This can effectively improve the overall sound insulation effect of the air module 1.

[0205] In practical applications, the air path module housing 10 can be made of a material with excellent sound insulation. For example, it can be made of sound-insulating engineering plastics or foamed sound-insulating materials. Of course, the air path module housing 10 can be a shell or a solid body.

[0206] It should be noted that if it is a shell, then the air module shell 10 can be filled with sound insulation cotton, the inner wall of the air module shell 10 can be affixed with sound insulation cotton, and / or the outer walls of the air inlet pipe 11 and the air outlet pipe 12 can be wrapped with sound insulation cotton. If it is a solid body, it may not be possible to fill or affix sound insulation cotton. However, since solid bodies themselves are a material with good sound insulation effect, in this case, it is not necessary to fill with sound insulation cotton, and rely on the sound insulation material of the solid body to isolate the noise in the air path within the air module shell 10.

[0207] In addition, the present disclosure also provides an attraction system with heat dissipation function.

[0208] Figure 3 This is a schematic structural diagram of a suction pump system with heat dissipation function according to an embodiment of the present disclosure. Figure 3 As shown, the system includes: a diaphragm pump 2, including a diaphragm pump air inlet 24 and a diaphragm pump air outlet 25; an air circuit module 1, including an air circuit module housing 10, an air inlet pipe 11 and an air outlet pipe 12 fixedly disposed within the air circuit module housing 10; the air inlet pipe 11 is in communication with a first air port 111 disposed on the first surface of the air circuit module housing 10, and the air outlet pipe 12 is in communication with a second air port 121 disposed on the first surface of the air circuit module housing 10; the first air port 111 is in communication with the diaphragm pump air inlet 24, and the second air port 121 is in communication with the diaphragm pump air outlet 25; a support portion 3, the support portion 3 being supported between the diaphragm pump 2 and the air circuit module housing 10, forming an accommodation space between the diaphragm pump 2 and the air circuit module 1 based on the support portion 3; and a heat dissipation fan 21, disposed within the accommodation space and at least used to dissipate heat from the diaphragm pump 2 and the air circuit module 1.

[0209] In practical applications, the diaphragm pump 2 of the suction pump system tends to generate heat during operation. If the diaphragm pump 2 overheats, its performance will be affected, and in severe cases, it may be damaged. Therefore, in order to ensure the stable operation of the diaphragm pump 2, the heat dissipation of the suction pump system must be improved.

[0210] The suction pump system primarily includes a diaphragm pump 2 and a connected air circuit. In this disclosed solution, the air circuit is encapsulated within an air circuit module 1. The air circuit module 1 serves as the base support, while the diaphragm pump 2 is supported above the air circuit module 1 by a support portion 3. This improves air circulation around the diaphragm pump 2.

[0211] Specifically, the air circuit module 1 encapsulates the air inlet pipe 11 and the air outlet pipe 12 in the air circuit module shell 10. The air circuit module shell 10 is a shell that is not easily deformed and can support the diaphragm pump 2. The air inlet pipe 11 is connected to the first air port 111 opened on the first surface of the air circuit module shell 10, and the first air port 111 is connected to the air inlet 24 of the diaphragm pump, thus constructing a complete air inlet air circuit relationship. Similarly, the air outlet pipe 12 is connected to the second air port 121 opened on the first surface of the air circuit module shell 10, thereby constructing a complete air outlet air circuit relationship. These intricate pipeline connection relationships are all encapsulated in the air circuit module shell 10, and only the first air port 111 and the second air port 121 connected to the diaphragm pump 2 are provided to the outside.

[0212] It should be noted that the first surface mentioned here refers to Figure 2 and Figure 3 The upper surface of the air circuit module housing 10 is shown. The first air port 111 and the second air port 121 are through holes opened on the first surface for connecting to an air pump.

[0213] To ensure that the diaphragm pump 2 is stably fixed above the air circuit module 1, it can be supported by a support portion 3. Specifically, one end of the support portion 3 is supported on the air circuit module housing 10, and the other end is supported on the bottom of the diaphragm pump 2, thereby forming an accommodation space between the diaphragm pump 2 and the air circuit module housing 10. This accommodation space allows for better air circulation below the diaphragm pump 2. At the same time, there is no obstruction above or around the diaphragm pump 2, creating excellent heat dissipation conditions for the diaphragm pump 2.

[0214] The accommodating space mentioned here can be understood as a space that can accommodate other objects or equipment. The accommodating space here is used to accommodate the cooling fan 21.

[0215] Furthermore, by arranging a heat dissipation fan 21 in the accommodating space, a heat dissipation airflow is actively provided for the diaphragm pump 2 , thereby effectively improving the heat dissipation effect of the diaphragm pump 2 .

[0216] Based on the above-disclosed solution, it can be seen that the inlet and outlet pipes 11, 12 are first encapsulated in the air module housing 10, which serves as a base for supporting the diaphragm pump 2. Furthermore, the diaphragm pump 2 is supported by the support portion 3 above the air module housing 10, forming an accommodation space, which creates excellent heat dissipation conditions for the diaphragm pump 2. Furthermore, a cooling fan 21 is installed in the accommodation space, which provides better heat dissipation for the diaphragm pump 2 and achieves heat dissipation through vertical air flow.

[0217] In one or more embodiments of the present disclosure, there are multiple support parts 3, each support part 3 is spaced apart, and the multiple support parts 3 are evenly arranged in the edge area of the first surface to form an accommodating space.

[0218] like Figure 1 and Figure 3 As shown, in order to provide more stable support for the diaphragm pump 2, multiple support portions 3 can be provided, and a certain spacing can be ensured between adjacent support portions 3. To facilitate the placement of the diaphragm pump 2, multiple support portions 3 are arranged in the edge area of the first surface, and no support portion 3 is arranged in the middle area of the first surface, so that the middle area forms a complete accommodating space.

[0219] Based on the above-mentioned disclosed solution, a accommodating space for dissipating heat from the diaphragm pump 2 is created by using the support portion 3 between the air path module 1 and the diaphragm pump 2. Moreover, although there are multiple support portions 3, they will not hinder the flow of gas, making the accommodating space an open space, and the heat dissipation effect is better.

[0220] In one or more embodiments of the present disclosure, at least one heat dissipation channel 13 is provided on the gas path module 1, and the heat dissipation channel 13 passes through the first surface of the gas path module housing 10 to the second surface of the gas path module housing 10, and the second surface and the first surface are two opposite surfaces of the gas path module housing 10.

[0221] In practical applications, such as Figure 1 As shown, at least one heat dissipation channel 13 is provided on the gas circuit module 1. The heat dissipation channel 13 runs through the gas circuit module housing 10, that is, the heat dissipation channel 13 runs from the first surface to the second surface of the gas circuit module housing 10. The second surface mentioned here is the surface opposite to the first surface. Specifically, the first surface is Figure 1 The second surface is the top surface of the gas path module housing 10 in the figures, and the second surface is the bottom surface of the gas path module housing 10 .

[0222] It should be noted that although the heat dissipation channel 13 passes through the gas module housing 10, it has side walls, meaning that the heat dissipation channel 13 is not connected to the interior of the gas module 1. While utilizing the heat dissipation channel 13 to improve heat dissipation, it also effectively prevents vibration and noise from being transmitted from the gas module 1.

[0223] In one or more embodiments of the present disclosure, a plurality of flexible feet 4 are provided on the second surface of the air circuit module housing 10 so that when the suction system is placed on a support surface, an air flow space is formed between the second surface and the support surface.

[0224] like Figure 1 and Figure 3 As shown, a plurality of flexible feet 4 are also provided on the second surface (i.e., the lower surface) of the air module housing 10. These flexible feet 4 support the air module 1 and create a space for air flow between the air module 1 and the supporting surface. This allows the heat dissipating air flowing through the heat dissipating channel 13 to flow smoothly through the air flow space between the second surface and the supporting surface, further enhancing the overall heat dissipation effect of the suction pump system.

[0225] In one or more embodiments of the present disclosure, the extension direction of the heat dissipation channel 13 is perpendicular to the first surface.

[0226] It should be noted that since the airflow generated by the cooling fan 21 flows from bottom to top perpendicular to the first surface, in order to better exert the heat dissipation effect of the heat dissipation channel 13, the extension direction of the heat dissipation channel 13 should be perpendicular to the first surface. This allows the airflow generated by the cooling fan 21 to pass through the heat dissipation channel 13 smoothly and quickly.

[0227] In one or more embodiments of the present disclosure, there is a first preset distance between the heat dissipation fan 21 and the diaphragm pump 2 , and there is a second preset distance between the heat dissipation fan 21 and the first surface.

[0228] In practical applications, such as Figure 1 As shown, the air inlet direction of the cooling fan 21 extends along the vertical axis toward the air circuit module housing 10, and the air outlet of the cooling fan 21 is arranged toward the diaphragm pump 2. In other words, when the cooling fan 21 rotates, the cooling airflow flows from the air circuit module housing 10 toward the diaphragm pump 2, so that the heat generated by the diaphragm pump 2 during operation is fully evacuated.

[0229] In actual application, in order to better dissipate heat from the cooling fan 21, when installing the cooling fan 21 into the accommodation space, it is necessary to ensure that a first preset distance is maintained between the cooling fan 21 and the diaphragm pump 2 above, and a second preset distance is maintained between the cooling fan 21 and the first surface below, so as to achieve the best heat dissipation effect brought by the cooling fan. The first preset distance and the second preset distance mentioned here are generally between 0.3D and 0.5D, where D refers to the diameter of the cooling fan 21.

[0230] Therefore, through the above disclosed solution, the first preset distance and the second preset distance are set appropriately, so that the heat dissipation fan 21 can achieve the best heat dissipation effect.

[0231] In one or more embodiments of the present disclosure, it is characterized in that the heat dissipation fan 21 is installed on the first surface via a plurality of mounting feet 14, so that a second preset distance is formed between the heat dissipation fan 21 and the first surface.

[0232] In actual application, when the cooling fan 21 is working, the air flow flows from one side of the cooling fan 21 to the other side. Since the cooling fan 21 is installed on the first surface of the air path module, although the cooling channel 13 is provided on the air path module housing 10, Figure 1 As shown, only certain locations begin the heat dissipation channel 13 opposite the heat dissipation fan 21, while in other locations the heat dissipation fan 21 is still adjacent to the first surface. To ensure smooth flow of heat dissipation air adjacent to the first surface, when the heat dissipation fan 21 is installed in the mounting hole on the first surface, the heat dissipation fan 21 is supported by multiple mounting legs 14, so that a second predetermined distance is formed between the heat dissipation fan 21 and the first surface.

[0233] It should be noted that since the cooling fan 21 may generate vibration or noise during rotation, flexible mounting feet 14 may be selected to prevent the vibration and noise of the cooling fan 21 from being transmitted to the air path module or to reduce the transmitted noise and vibration.

[0234] In one or more embodiments of the present disclosure, each mounting foot 14 is located within the edge region.

[0235] like Figure 3 As shown, in addition to the cooling fan 21, a support portion 3 is also installed on the first surface. The support portion 3 is configured in the edge area of the first surface. Therefore, when installing the cooling fan 21, it is necessary to avoid the interference and influence of the support portion 3. When installing the cooling fan 21, choose to install it in the vacant area of the first surface. For example, Figure 3 As mentioned above, the mounting feet 14 are provided between the two sets of support parts 3. Thus, the rectangular sides of the heat dissipation fan 21 are not parallel to the rectangular sides of the air path module housing 10, so that the limited space of the first surface is fully utilized.

[0236] In practical applications, if the accommodation space allows, a larger cooling fan 21 is preferred. Figure 3 As shown, the heat dissipation fan 21 is a rectangular fan, and the corresponding mounting feet 14 are located at the four corners of the heat dissipation fan 21. This allows the heat dissipation fan 21 to generate greater heat dissipation wind force.

[0237] In one or more embodiments of the present disclosure, a radiator 22 is further included. The radiator 22 is disposed on a surface of the diaphragm pump 2 that is away from the cooling fan 21. Furthermore, ventilation holes 23 may be provided on a side surface (i.e., bottom surface) of the diaphragm pump 2 that is close to the cooling fan 21. When the cooling fan rotates, cooling airflow may be directly blown into the diaphragm pump 2 through the ventilation holes 23.

[0238] like Figure 3 As shown, a radiator 22 is provided on the diaphragm pump 2. Specifically, the radiator 22 is installed on the surface of the diaphragm pump 2 away from the cooling fan 21. Including, the upper surface, left surface and right surface of the diaphragm pump 2.

[0239] The radiator 22 mentioned here can be a fin-type radiator, so that the surface of the diaphragm pump 2 that cannot be directly blown by the cooling fan 21 can also fully dissipate heat, further improving the heat dissipation effect of the diaphragm pump 2.

[0240] In one or more embodiments of the present disclosure, the radiator 22 has heat dissipation fins 222 and a fitting portion 221 . The radiator 22 fits the surface of the diaphragm pump 2 based on the fitting portion 221 and dissipates heat from the diaphragm pump 2 via the heat dissipation fins 222 .

[0241] like Figure 5 This is a schematic diagram of the structure of the finned heat sink provided by the present invention. Figure 5As can be seen in the figure, the radiator 22 has heat dissipation fins 222 and a fitting portion 221. The fitting portion 221 is used to fit the surface of the diaphragm pump 2. Since the upper surface of the diaphragm pump 2 is an arc-shaped structure, in order to make the fitting portion 221 fit more closely with the diaphragm pump 2, the fitting portion 221 is also configured to have the same arc-shaped structure as the surface of the diaphragm pump 2. The heat generated by the diaphragm pump 2 during operation can be conducted through the outer shell of the diaphragm pump 2 to the fitting portion 221, and then from the fitting portion 221 to the heat dissipation fins 222, and finally dissipated to the outside through the heat dissipation fins 222.

[0242] Based on the above disclosed solutions, it can be seen that by attaching the radiator 22 to the outer surface of the diaphragm pump 2, the diaphragm pump 2 can effectively dissipate heat from all directions, thereby improving the heat dissipation efficiency of the diaphragm pump 2.

[0243] In one or more embodiments of the present disclosure, the fitting portion 221 is a semi-enclosed fitting portion 221 , so that the heat dissipation fan 21 can provide airflow to the area of the diaphragm pump 2 not fitted by the semi-enclosed fitting portion 221 .

[0244] In actual application, since the cooling fan 21 is arranged below the diaphragm pump 2, the cooling fan 21 can blow air directly toward the bottom surface of the diaphragm pump 2, so that the bottom surface of the diaphragm pump 2 that is not in contact with the radiator 22 can also be effectively cooled.

[0245] It should be noted that during operation of the cooling fan 21 , the airflow will blow toward the bottom surface of the diaphragm pump 2 , and then continue to flow along the side walls of the diaphragm pump 2 , thereby improving the heat dissipation efficiency of the heat dissipation fins 222 .

[0246] The radiator 22 mentioned here can be made of aluminum alloy, pure copper, stainless steel, carbon fiber composite material, etc., or the bonding portion can be made of pure copper and the heat dissipation fins can be made of aluminum alloy. In actual application, the user can select the appropriate radiator 22 material according to actual needs.

[0247] In one or more embodiments of the present disclosure, the heat sink 22 includes three groups of heat dissipating fins, and the second group of heat dissipating fins is disposed between the first group of heat dissipating fins and the third group of heat dissipating fins.

[0248] In practical applications, the radiator 22 can be composed of three parts: a first set of fins, a second set of fins, and a third set of fins. When mounted on the diaphragm pump 2, the second set of fins is positioned between the first and third sets of fins. In other words, the second set of fins is mounted on top of the diaphragm pump 2, while the first and third sets of fins are mounted on the left and right sides, respectively. It should be noted that the three sets of fins are formed integrally with their respective contact areas.

[0249] In an optional solution, the radiator 22 can be an integral body, that is, the fitting portion and the heat dissipation fins are integrally formed, and then the radiator 22 is fitted onto the outer shell of the diaphragm pump 2 according to the arc shape.

[0250] Based on the above disclosed solution, the heat sink 22 is formed by integrally forming the fitting portion 221 and the heat dissipation fins 222 , which can effectively improve the heat dissipation effect of the heat sink 22 .

[0251] In one or more embodiments of the present disclosure, the second group of heat dissipating fins includes a plurality of heat dissipating fins, a main extension direction of the second group of heat dissipating fins is perpendicular to the first surface, and a preset distance exists between two adjacent heat dissipating fins.

[0252] In actual use, the second set of fins is provided with multiple fins, and adjacent fins are spaced apart at a predetermined distance, thereby allowing airflow to flow between the two adjacent fins, thereby improving heat dissipation efficiency. Furthermore, because the second set of fins is disposed on top of the diaphragm pump 2, the fins in the second set of fins extend perpendicular to the first surface.

[0253] In one or more embodiments of the present disclosure, the first group of heat dissipating fins includes a plurality of heat dissipating fins, the main extension direction of the first group of heat dissipating fins is parallel to the first surface, and there is a preset spacing between two adjacent heat dissipating fins; the third group of heat dissipating fins includes a plurality of heat dissipating fins, the main extension direction of the third group of heat dissipating fins is parallel to the first surface, and there is a preset spacing between two adjacent heat dissipating fins.

[0254] As mentioned above, the first and third groups of heat dissipating fins are respectively arranged on both sides of the diaphragm pump 2. Therefore, the fin extension direction of the first group of heat dissipating fins is parallel to the first surface, and the fin extension direction of the third group of heat dissipating fins is also parallel to the first surface.

[0255] In addition, in order to achieve better heat dissipation effect of the first and third groups of heat dissipating fins, it is necessary to ensure that there is a preset distance between two adjacent heat dissipating fins. Here, by arranging two adjacent fins at a preset distance, it is conducive to airflow through the distance, thereby improving heat dissipation efficiency.

[0256] It should be noted that the radiator 22 described above is disposed on the motor housing of the diaphragm pump 2. Generally, the radiator 22 evenly covers a designated surface of the motor housing, that is, the length of the radiator 22 is the same as the length of the motor housing, thereby improving heat dissipation efficiency.
