Description

Technical Field

[0001] This application relates to the field of air pump technology, and more particularly to an integrated pump. Background Technology

[0002] An integrated pump-valve air pump is a device that combines the functions of a pump and a valve, typically used in industrial, medical, and scientific research fields. It not only possesses the basic functions of an air pump but also integrates valve control, enabling more precise gas control and regulation.

[0003] Understandably, an integrated air pump mainly consists of two parts: the pump body and the control valve. However, a typical air pump uses a peripheral air intake and central air outlet method, which makes it difficult to set the installation position of the control valve. Therefore, this solution aims to solve the above problem by changing the air intake and outlet method. Utility Model Content

[0004] The purpose of this application is to provide an integrated pump to solve at least one of the above-mentioned technical problems.

[0005] To solve the above-mentioned technical problems, this application provides an integrated pump, including a pump body and a control valve disposed on the pump body;

[0006] The pump body includes a pump body and a motor located at the end of the pump body away from the control valve;

[0007] The pump body includes an upper shell assembly, a lower shell assembly, and an air pump assembly. The upper shell assembly and the lower shell assembly cooperate to form an accommodating space suitable for accommodating the air pump assembly. The motor is located on the lower shell assembly and its drive end is connected to the air pump assembly.

[0008] The upper shell assembly includes a top shell, a middle shell, a bottom shell stacked sequentially, and a valve plate disposed between the top shell and the middle shell;

[0009] A first groove is provided at the center of the top shell, and a plurality of first air inlets are provided in the first groove; a second groove is provided on one side of the top shell, and a first air outlet is provided in the second groove, and the control valve is connected to the first air outlet; a vent pipe is also provided on the top shell, and the first groove is located between the vent pipe and the second groove.

[0010] A cover is provided on the first groove;

[0011] In the above implementation process, this solution adjusts the main air inlet of the pump body, namely the first air inlet hole, to the center of the top shell, while setting the air outlet, namely the first air outlet hole, on the side near the top shell. The first groove where the first air inlet hole is located is further filled by the cover, thereby realizing the mode of air inlet in the middle and air outlet on the side. In this structural mode, the position of the control valve is better adjusted, which makes the overall structure of the integrated pump more compact and conducive to miniaturization and micro-miniaturization.

[0012] Preferably, the top shell has a cavity block and a sealing protrusion formed on the side near the cover body. The sealing protrusion is adapted to abut against the surface of the valve plate and form a first cavity, a second cavity and a third cavity. The cavity block forms a fourth cavity.

[0013] A first vent hole and a second vent hole are formed on the cavity block;

[0014] A third vent hole, a fourth vent hole, and a fifth vent hole are formed on the valve plate;

[0015] A third groove adapted to the valve plate is formed on the middle shell, and a sixth vent hole, a seventh vent hole and an eighth vent hole are provided in the third groove;

[0016] The first air inlet is connected to the fourth cavity, and the second vent is connected to the fourth cavity and a cavity body; the first vent is connected to the third cavity and the fourth cavity;

[0017] The first vent, the third vent, and the sixth vent are aligned, and a first diaphragm is provided on the third vent, the first diaphragm being adapted to abut against the first vent.

[0018] The fourth vent and the seventh vent are aligned, and a second diaphragm is provided on the fourth vent. The second diaphragm is adapted to abut against the seventh vent. The second cavity connects the fourth vent and the first vent.

[0019] The fifth vent hole connects to the eighth vent hole and the second cavity;

[0020] In the above implementation process, when the pump body is working, the motor drives the air pump assembly to create air pressure changes. The airflow enters the fourth cavity from the first air inlet. The fourth cavity is connected to the third cavity through the first vent. The airflow then enters the third cavity through the first vent. The airflow in the third cavity can push open the first diaphragm and pass through the third vent and then through the sixth vent on the middle shell. The output airflow can then push open the second diaphragm on the valve plate through the fourth vent and then enter the second cavity and be discharged through the first air outlet. In this process, the first and second diaphragms play a unidirectional guiding role, thereby making the airflow flow stably in a fixed direction. It can be understood that this solution achieves air intake in the middle and air outlet on the side of the pump body through structural improvements to the top shell, middle shell, and valve plate, which facilitates better assembly of the subsequent control valve.

[0021] Preferably, the first vent is connected to the second cavity.

[0022] Preferably, the vent pipe has a vent hole, which communicates with the second cavity.

[0023] Preferably, a pressure relief valve is provided in the vent hole.

[0024] Preferably, the control valve includes a mounting bracket, a valve body, and an air outlet.

[0025] The valve body and the air outlet are mounted on the mounting bracket, and the air outlet is connected to the first air outlet hole; it also includes a fixing member suitable for passing through the top shell, and the fixing member is used to fix the mounting bracket to the top shell;

[0026] In the above implementation process, the fixing component is used to fix the mounting bracket to the top shell, and the valve body is used to control the air outlet of the air nozzle.

[0027] Preferably, an annular groove is formed around the second groove outside the second groove, and a sealing ring is provided in the annular groove;

[0028] In the above implementation process, this solution further provides a sealing ring to improve the airtightness of the airflow connection between the control valve and the pump body, while the second groove can position the sealing ring to achieve stable assembly.

[0029] Preferably, a first limiting groove is formed on the outer wall of the pump body, and a locking boss is formed on the end face of the top shell and the lower shell assembly within the first limiting groove;

[0030] It also includes a retaining spring adapted to be inserted into the limiting groove, the two ends of the retaining spring clamping the locking bosses at both ends of the pump body to clamp the upper shell assembly and the lower shell assembly;

[0031] The first limiting groove and the snap ring are both provided in multiple ways and are arranged in a one-to-one correspondence;

[0032] In the above implementation process, after the upper shell assembly and the lower shell assembly are spliced ​​together, they can be clamped by a snap ring. This method can effectively simplify the fixing structure. Compared with the fixing screw method, the assembly efficiency is higher and the space occupied is smaller. That is, there is no need to set screw fixing holes externally, which is conducive to the miniaturization and micro-miniaturization of the integrated pump.

[0033] Preferably, a locking block is provided on the outer wall of the pump body; it also includes an outer shell, the outer shell forming a receiving cavity suitable for accommodating the control valve, and a locking groove formed on the side wall of the outer shell to engage with the locking block;

[0034] In the above implementation process, this solution further provides an outer casing that can protect the control valve and also further improve the stability of the assembly; the snap-fit ​​connection of the outer casing also improves the convenience of assembly or disassembly, making it easier for subsequent maintenance.

[0035] Preferably, the cover is a sound-absorbing cover;

[0036] In the above implementation, when the airflow enters the pump body from the first air inlet, the muffler cover can effectively reduce the noise generated during the process, thus ensuring air intake efficiency while effectively controlling noise generation.

[0037] Compared with the prior art, the beneficial effects of this application are as follows: This solution adjusts the main air inlet of the pump body, namely the first air inlet hole, to the center of the top shell, while the air outlet, namely the first air outlet hole, is set on the side near the top shell. The first groove where the first air inlet hole is located is further filled by the cover, thereby realizing the mode of air inlet in the middle and air outlet on the side. In this structural mode, the position of the control valve is better adjusted, which makes the overall structure of the integrated pump more compact and conducive to miniaturization and micro-miniaturization.

[0053] Example

[0054] An integrated pump-valve air pump is a device that combines the functions of a pump and a valve, typically used in industrial, medical, and scientific research fields. It not only possesses the basic functions of an air pump but also integrates valve control, enabling more precise gas control and regulation. Understandably, an integrated air pump mainly consists of two parts: the pump body and the control valve. However, conventional air pumps use a peripheral air intake and central air outlet method, which makes it difficult to set the installation position of the control valve. Therefore, this solution aims to solve the above problem by changing the air intake and outlet method.

[0055] For details, please see Figure 1-9 This embodiment provides an integrated pump, including a pump body 10 and a control valve 21 disposed on the pump body 10;

[0056] Specifically, the pump body 10 includes a pump body 11 and a motor 12 located at the end of the pump body 11 away from the control valve 21;

[0057] Specifically, the pump body 11 includes an upper shell assembly 40, a lower shell assembly 30, and an air pump assembly 60. The upper shell assembly 40 and the lower shell assembly 30 cooperate to form an accommodating space suitable for accommodating the air pump assembly 60.

[0061] In the above scheme, the main air inlet of the pump body 10, namely the first air inlet 412, is adjusted to the center of the top shell 41, while the air outlet, namely the first air outlet 4141, is set on the side near the top shell 41. The first groove 411 where the first air inlet 412 is located is further filled by the cover 45, thereby realizing the mode of air inlet in the middle and air outlet on the side. In this structural mode, the position of the control valve 21 can be better adjusted, which makes the overall structure of the integrated pump more compact and is conducive to miniaturization and micro-miniaturization.

[0062] Specifically, the air pump assembly 60 includes an air bladder bowl 61 and a bracket. The air bladder bowl 61 is mounted on the bracket (not shown in the figure), and there are several air bladder bowls 61. The bracket is connected to a rotating seat (not shown in the figure). When the motor 12 is working, it can drive the rotating seat to rotate, thereby enabling the air bladder bowl 61 to perform a suction action, which in turn drives the airflow.

[0063] It should be noted that the air pump assembly 60 is a relatively mature technology in the prior art, that is, this part of the structure can be obtained from the prior art. Therefore, this application will not elaborate on its specific structure and working principle. However, it is understood that this will not affect the understanding of the overall solution by those skilled in the art.

[0064] For details, please see Figure 5-8The top shell 41 has a cavity block 415 and a sealing protrusion on the side near the cover 45.

[0071] Specifically, the fifth vent 443 is connected to the eighth vent 424 and the second cavity 52;

[0072] In the above scheme, when the pump body 10 is working, the motor 12 drives the air pump assembly 60 to generate air pressure changes. The airflow enters the fourth cavity from the first air inlet 412. The fourth cavity is connected to the third cavity 53 through the first vent 416. The airflow then enters the third cavity 53 through the first vent 416. The airflow in the third cavity 53 can push open the first diaphragm 4411 and pass through the third vent 441 and then through the sixth vent 422 on the middle shell 42. The output airflow can pass through the seventh vent 422 on the middle shell 42. 23 Then the second diaphragm 4421 on the valve plate 44 is opened and the air enters the second cavity 52 through the fourth vent 442 and is discharged through the first vent 4141. In this process, the first diaphragm 4411 and the second diaphragm 4421 play a unidirectional guiding role, thereby making the airflow flow stably in a fixed direction. It is understood that this solution achieves air intake in the middle and air outlet on the side of the pump body 10 through the structural improvement design of the top shell 41, the middle shell 42 and the valve plate 44, so as to facilitate better assembly of the subsequent control valve 21.

[0073] Specifically, the first vent 4141 connects to the second cavity 52.

[0078] In the above scheme, the fixing member 418 is used to fix the mounting bracket 211 to the top shell 41, and the valve body 212 is used to control the air outlet of the air nozzle. It is understood that the structure of the control valve 21 part in this integrated pump is a relatively mature technology in the prior art, so this scheme will not elaborate on it further.

[0079] Specifically, an annular groove 4142 is formed around the second groove 414, and a sealing ring 4143 is provided in the annular groove 4142.

[0080] In the above scheme, the sealing ring 4143 is further provided to improve the airtightness of the airflow passage between the control valve 21 and the pump body 10, while the second groove 414 can position the sealing ring 4143 to achieve stable assembly.

[0081] Specifically, a first limiting groove 71 is formed on the outer wall of the pump body 11, and a locking boss 72 is formed on the end face of the top shell 41 and the lower shell assembly 30 within the first limiting groove 71.

[0082] Furthermore, it also includes a retaining spring 70 suitable for snapping into the limiting groove, the two ends of the retaining spring 70 clamping the locking bosses 72 at both ends of the pump body 11 to clamp the upper shell assembly 40 and the lower shell assembly 30.

[0083] Specifically, the first limiting groove 71 and the retaining ring 70 are provided in multiple ways and are arranged in a one-to-one correspondence;

[0084] In the above solution, after the upper shell assembly 40 and the lower shell assembly 30 are spliced ​​together, they can be clamped by the snap ring 70. This method can effectively simplify the fixing structure. Compared with the fixing screw method, the assembly efficiency is higher and the space occupied is smaller. That is, there is no need to set screw fixing holes externally, which is conducive to the miniaturization and micro-miniaturization of the integrated pump.

[0085] For details, please see Figure 1 The pump body 11 has a locking block 221 on its outer wall; it also includes an outer shell 22, which has a receiving cavity suitable for accommodating the control valve 21, and a locking groove 222 that engages with the locking block 221 is formed on the side wall of the outer shell 22.

[0087] Specifically, cover 45 is a sound-absorbing cover;

[0088] In the above scheme, when the airflow enters the pump body 11 from the first air inlet 412, the muffler cover can effectively reduce the noise generated in the process, thus ensuring air intake efficiency while effectively controlling noise generation.
