DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0035] Please refer to Figures 1-7 In the embodiments of the utility model, a pump valve assembly 24 convenient to install comprises a shell 1 and a pump valve mechanism and a fixed block 2 installed in the shell 1. The pump valve mechanism comprises a pipeline joint piece 3, a connecting pipe 4 and a pump valve assembly 5. The pipeline joint piece 3 and the pump valve assembly 5 are connected through the connecting pipe 4 and form an integrated structure. The fixed block 2 is used to realize the connection with the shell 1 and the fixation of the pipeline joint piece 3.

[0036] The utility model discloses technical scheme, pipeline joint subassembly is used for connecting external pipeline, and makes fluid can enter or flow out pump valve assembly 24, and the connecting pipe 4 plays the role of connecting pipe 4 pipeline joint subassembly and pump valve subassembly 5, ensures that fluid can flow smoothly between each component, and the combination of pump and valve of pump valve subassembly 5 is used for realizing the transport and control function of fluid, specifically, as in breast pump, pipeline joint piece 3 is usually responsible for connecting with the component such as milk storage bottle or breast pump cover of breast pump, ensures that milk water can pass smoothly, and the connecting pipe 4 plays the role of transmission milk water or gas, and pump valve subassembly 5 is connected with pipeline joint piece 3, and pump valve subassembly 5 is the core part of whole pump valve mechanism, and it realizes the breast pump and air release function of breast pump by controlling the flow of gas, and by connecting the three components into an integral structure, when installing pump valve assembly 24 of breast pump, this integral body can be directly pushed into the shell 1, without installing each component respectively as in traditional mode, greatly simplifying the installation step,

[0037] The fixed block 2 is mainly used for fixing the pipeline joint piece 3 in the pump valve assembly 24, specifically, as in breast pump, the pipeline joint piece 3 needs to bear certain pressure and tension, and if not fixed by the fixed block 2, looseness or displacement is prone to occurring, thereby affecting the transmission of milk water and the normal work of the breast pump, the fixed block 2 tightly clamps the pipeline joint piece 3 through specific structural design, so that the pipeline joint piece 3 remains stable during equipment operation, and the design of the fixed block 2 fully considers the shape and size of the pipeline joint piece 3, so as to ensure that reliable fixing effect can be provided, although the fixed block 2 is mainly used for fixing the pipeline joint piece 3, it also plays an auxiliary role in the stability of the whole pump valve assembly 24 to a certain extent, by fixing the pipeline joint piece 3, the fixed block 2 indirectly affects the connection stability between the pump valve mechanism and the shell 1, thereby providing guarantee for the normal operation of the whole pump valve assembly 24,

[0038] Among them, the pump valve assembly 5 can be fixed in a screw fastening mode, the pump valve assembly 5 is a key component for realizing functions, and needs to maintain a stable working state, the screw fastening mode can provide reliable fixing force, so as to ensure that the pump valve assembly 5 will not loosen or displace during equipment operation, and at the same time, the screw fastening mode is also convenient for dismounting and installing when the pump valve assembly 5 needs to be repaired or replaced,

[0039] In summary:

[0040] 1) The user needs to spend a lot of time and effort to put the pipe joint piece 3, the connecting pipe 4 and the pump valve assembly 5 into the shell 1 one by one and perform complex connection operation when installing each component of the traditional breast pump pump valve assembly 24 respectively. Now, since the pump valve mechanism forms an integrated structure, the user only needs to push it into the shell 1 as a whole and then perform simple fixing through the fixing block 2, which greatly reduces the installation steps and operation time, and even non-professionals can easily complete the installation, improving the installation efficiency.

[0041] 2) In the actual use of the breast pump, the stability of the connection is crucial. The integrated pump valve mechanism avoids the problem of loose connection that may occur when installing each component separately. The tight connection between the components reduces the probability of leakage and other failures, ensuring that the milk can flow smoothly inside the breast pump. At the same time, the fixing effect of the fixing block 2 further enhances the stability of the pipe joint piece 3 and the entire pump valve mechanism. Whether during the breast pumping process or during the movement and transportation of the equipment, the pump valve assembly 24 can be ensured not to loosen or displace, ensuring that the equipment can work stably and reliably during operation.

[0042] 3) The convenient installation method not only reduces the user's trouble in installing the breast pump, but also reduces the risk of equipment failure caused by improper installation. The user can use the breast pump more easily without worrying about the complex installation process. At the same time, the stable performance can provide better user experience, meet the user's demand for efficient and reliable operation of the equipment, and the user can use the breast pump more confidently and focus on taking care of the baby without worrying about equipment problems.

[0043] 4) Good connection stability and fixing method help the pump valve assembly 24 to perform best. In the breast pump, the performance of the pump valve assembly 24 directly affects the pumping effect and efficiency. Through integrated design and auxiliary fixing of the fixing block 2, the pump valve assembly 24 can work more stably to ensure that the breast pump can provide stable suction and air release functions, thereby improving the performance of the entire equipment. This not only improves the use effect of the breast pump, but also prolongs the service life of the equipment, bringing more value to the user.

[0044] In the embodiment of the utility model, the pump valve assembly 5 includes a damping box 14, at least one group of pump valve bodies installed in the damping box 14, and a pressure sensor 15 and a PCB board 16 installed on the outside of the damping box 14, and the pump valve body and the pressure sensor 15 are electrically connected with the PCB board 16.

[0045] Among them, the connecting pipe 4 has a first pipe 17 connected to the pressure sensor 15 and a second pipe 18 connected to the pump valve body.

[0046] The pump valve assembly 5 is composed of a shock-absorbing box 14, a pump valve body, a pressure sensor 15 and a PCB board 16. The shock-absorbing box 14 provides protection and shock-absorbing effect for the pump valve body inside, reduces the influence of external vibration on the pump valve body during the operation of the breast pump and the like, and ensures stable work of the pump valve body. The pump valve body is a core component for realizing the function of the pump valve, and completes the operation of the breast pump and the like by controlling the flow of gas or liquid. The pressure sensor 15 is installed outside the shock-absorbing box 14, is used for detecting the pressure change in the pump valve system, and transmits the pressure signal to the PCB board 16. The PCB board 16 plays a role of controlling and processing signals, receives signals from the pressure sensor 15 and the pump valve body, and analyzes and processes the signals according to a preset program, so as to realize accurate control of the pump valve system. The pump valve body can be provided with one or two groups, and correspond to a single-pump breast pump or a double-pump breast pump. The pressure sensor 15 and the PCB board 16 can be fixed outside the shock-absorbing box 14 by clamping, screw fastening and the like.

[0047] The connecting pipe 4 is divided into a first pipe 17 and a second pipe 18. The first pipe 17 is connected with the pressure sensor 15, connects the pressure sensor 15 with other parts in the pump valve system, and enables the pressure sensor 15 to accurately detect the pressure change in the system. The second pipe 18 is connected with the pump valve body, ensures the smooth fluid passage between the pump valve body and other components, and realizes smooth transmission of milk or gas.

[0048] The design of the whole pump valve assembly 24 is an organic whole. The pipe joint piece 3, the connecting pipe 4, the pump valve assembly 5 and the fixing block 2 cooperate with each other, and together realize efficient operation of the breast pump and the like. The integrated pump valve mechanism makes installation more convenient. The fixing block 2 ensures the stability of the pipe joint piece 3, and the components in the pump valve assembly 5 work cooperatively to provide stable pressure control and accurate flow regulation for the equipment.

[0049] In the embodiment of the utility model, the joint of pipe joint piece 3 corresponds with pressure sensor 15, so that first pipe 17 is located between pipe joint piece 3 and pressure sensor 15, wherein, second pipe 18 is connected to first pipe 17.

[0050] The joint of the pipe joint piece 3 is correspondingly arranged with the pressure sensor 15. This design enables the first pipe 17 to be naturally located between the pipe joint piece 3 and the pressure sensor 15. In the breast pump and the like, such a layout can ensure that the pressure sensor 15 can accurately detect the fluid pressure passing through the pipe joint piece 3. By placing the first pipe 17 in this specific position, the pressure sensor 15 can more directly perceive the pressure change in the system, improving the accuracy and timeliness of pressure detection.

[0051] The second pipeline 18 is connected to the first pipeline 17, and the connection forms a continuous fluid channel between the pump valve body and the pressure sensor 15. During the operation of the pump valve assembly 24, the fluid (such as milk or gas) first passes through the pipeline joint 3 and then passes through the first pipeline 17 to the pressure sensor 15. After the pressure sensor 15 detects the pressure change, a signal is transmitted to the PCB board 16, which controls the working state of the pump valve body according to the pressure signal. The pump valve body controls and regulates the fluid through the connection between the second pipeline 18 and the first pipeline 17.

[0052] The various components of the entire pump valve assembly 24 cooperate to achieve the function of the device. The specific connection relationship between the pipeline joint 3, the pressure sensor 15, the first pipeline 17, the second pipeline 18, and the pump valve body allows the fluid to flow smoothly in the system. At the same time, the pressure sensor 15 can accurately detect the pressure change, and the pump valve body can accurately control according to the pressure signal. This collaborative working principle ensures the efficient operation of the pump valve assembly 24 in devices such as breast pumps.

[0053] Furthermore, the joint of the pipeline joint 3 is arranged corresponding to the pressure sensor 15, so that the first pipeline 17 connecting the two can maintain a short length. Based on a deep understanding of fluid mechanics and gas transmission principles, this design is based on a deep understanding of fluid mechanics and gas transmission principles. A shorter connecting air pipe can reduce the resistance of gas during transmission, ensuring smoother gas flow. When gas flows in a shorter pipeline, it encounters less friction and resistance, so it can reach the pressure sensor 15 more quickly to achieve accurate pressure detection. In a breast pump, accurate pressure detection is crucial to providing the right suction, ensuring stable and reliable performance of the breast pump. This layout also takes into account the ease of manufacturing. Shorter air pipes are easier to process and assemble during manufacturing, reducing production costs and process difficulty. At the same time, due to the shorter length, the demand for materials is relatively small, further improving production efficiency.

[0054] In the embodiment of the utility model, the pump valve body includes a gas pump 19 and an electromagnetic valve 20 placed in the shock-absorbing box 14. The interface of the gas pump 19 corresponds to the interface of the electromagnetic valve 20. The second pipeline 18 is provided with a first communication port 21 and a second communication port 22 corresponding to the interface of the gas pump 19 and the interface of the electromagnetic valve 20, respectively.

[0055] The pump valve body is composed of a gas pump 19 and an electromagnetic valve 20, which is placed in the shock-absorbing box 14. In devices such as breast pumps, the gas pump 19 is mainly responsible for generating gas pressure, which is connected to the external pipeline through its interface to deliver gas to the system. The electromagnetic valve 20 is used to control the flow direction and on-off of the gas, and its interface corresponds to the interface of the gas pump 19 to realize the cooperative work between the two.

[0056] The second pipeline 18 is provided with a first communication port 21 and a second communication port 22 corresponding to the air pump 19 interface and the electromagnetic valve 20 interface respectively, which can be closely connected with the pump valve body, ensure the smooth flow of gas in the system, the first communication port 21 is connected with the air pump 19 interface, and the gas generated by the air pump 19 is transported into the second pipeline 18; the second communication port 22 is connected with the electromagnetic valve 20 interface, so that the electromagnetic valve 20 can control the gas flow in the second pipeline 18;

[0057] Furthermore, the electromagnetic valve 20 gas nozzle is arranged corresponding to the pump gas nozzle, so that the gas pipe connected with the two can keep a short length, in the pump valve assembly 24, the design fully considers the characteristics of gas flow, the short gas pipe can reduce the resistance of gas in the transmission process, make the gas path more smooth, the gas encounters smaller friction and resistance when flowing in a short distance, can be transmitted from the electromagnetic valve 20 to the pump more quickly, improve the response speed and working efficiency of the system; such layout is also beneficial to the manufacture of the gas pipe, the shorter gas pipe is simpler in the manufacturing process, reduces the production cost and process difficulty, the simple gas pipe can improve the production efficiency, and also helps to ensure the quality stability of the gas pipe.

[0058] In the embodiment of the utility model, the shell 1 has a first assembly position 6 corresponding to the pipeline joint piece 3 and a second assembly position 7 corresponding to the pump valve assembly 5, and the pipeline joint piece 3 is inserted into the first assembly position 6.

[0059] The fixing block 2 is inserted into the first assembly position 6 and abuts against the pipeline joint piece 3, so that the pipeline joint piece 3 is limited in the first assembly position 6.

[0060] The first assembly position 6 corresponding to the pipeline joint piece 3 and the second assembly position 7 corresponding to the pump valve assembly 5 are divided in the design of the shell 1, and the clear partition design makes each component have a specific position during installation, which is convenient for orderly assembly; for breast pumps and other devices, the pipeline joint piece 3 usually needs to be connected with external milk storage bottles, breast cups or external pipes and other components, and is designed in the first assembly position 6, which is convenient for external connection and also provides a stable interface for the internal pump valve mechanism; the pump valve assembly 5 as the core working component is placed in the second assembly position 7, which is beneficial to the connection and cooperative work with other components.

[0061] The pipe joint 3 is inserted into the first assembly position 6, and the insertion is achieved by structural cooperation, thereby achieving rapid positioning and preliminary fixing; the insertion design enables the pipe joint 3 to be accurately installed at a specified position, thereby avoiding positional deviation during installation; the fixing block 2 is inserted into the first assembly position 6 and is in abutting association with the pipe joint 3; when the fixing block 2 is inserted into the first assembly position 6, a certain pressure is generated by contact with the pipe joint 3, thereby limiting the pipe joint 3 in the first assembly position 6; this design utilizes the structure and positional relationship of the fixing block 2, thereby achieving further fixing of the pipe joint 3; that is, the insertion cooperation of the fixing block 2 ensures the stability of the fixing block 2 in the housing 1, and the abutting association with the pipe joint 3 directly transmits the fixing effect to the pipe joint 3, thereby preventing loosening or displacement of the pipe joint 3 during operation of the equipment.

[0062] In the embodiment of the utility model, the fixing block 2 and the pipe joint 3 are inserted into the first assembly position 6 in wedge-shaped cooperation.

[0063] Wedge-shaped cooperation is a connection mode utilizing the principle of inclined plane; when the fixing block 2 and the pipe joint 3 are in wedge-shaped cooperation, the process is similar to inserting a wedge into a gap; as the insertion proceeds, due to the effect of the inclined plane, an increasingly greater extrusion force is generated between the fixing block 2 and the pipe joint 3, thereby achieving tight insertion into the first assembly position 6.

[0064] Wedge-shaped cooperation makes the connection between the fixing block 2 and the pipe joint 3 more secure, and in the process of use, the fixing block 2 and the pipe joint 3 are not prone to loosening or separation due to external forces, thereby effectively ensuring stable operation of the pump valve assembly.

[0065] When the pipe joint 3 is placed in the first assembly position 6, it can be preliminarily positioned by a corresponding clamping structure; for example, the lower end of the pipe joint 3 has a clamping block, and the first assembly position 6 has a clamping groove corresponding to the clamping block.

[0066] In the embodiment of the utility model, the side of the pipe joint 3 cooperating with the fixing block 2 has a first limiting protrusion 8, the side of the fixing block 2 cooperating with the pipe joint 3 has a second limiting protrusion 9, and the first limiting protrusion 8 and the second limiting protrusion 9 are in staggered correspondence to form a limiting structure.

[0067] The side of the pipe joint 3 cooperating with the fixing block 2 is provided with the first limiting protrusion 8, the side of the fixing block 2 cooperating with the pipe joint 3 is provided with the second limiting protrusion 9, the first limiting protrusion 8 and the second limiting protrusion 9 correspond to each other in structure but are in a staggered state; when the fixing block 2 and the pipe joint 3 are assembled together, the first limiting protrusion 8 and the second limiting protrusion 9 are interlaced (up and down), thereby forming a limiting structure; this design utilizes the shape and positional relationship of the protrusions, thereby achieving further fixing and limiting of the pipe joint 3.

[0068] In the equipment such as breast pump, the pipeline joint piece 3 needs to be connected with external components, and bears certain pressure and tension during the operation of the equipment, by setting the first limiting protrusion 8 and the second limiting protrusion 9, the contact area and friction force between the pipeline joint piece 3 and the fixing block 2 can be increased, and the stability of the fixing is improved; meanwhile, the design of staggered correspondence makes the limiting more firm, and prevents the pipeline joint piece 3 from loosening and displacement in each direction.

[0069] In the embodiment of the utility model, one end of the fixing block 2 inserted into the first assembly position 6 forms the first abutting end 10 which abuts and cooperates with the pipeline joint piece 3;

[0070] The end of the fixing block 2 away from the first abutting end 10 extends out of the first assembly position 6 and forms the second abutting end 25 which abuts and cooperates with the shell cover 26 of the shell 1.

[0071] The positioning and fixing are realized by abutting: by setting the first abutting end 10 and the second abutting end 25 at both ends of the fixing block 2 respectively, the abutting cooperation with the pipeline joint piece 3 and the shell cover 26 of the shell 1 is realized, when the fixing block 2 is inserted into the first assembly position 6, the first abutting end 10 contacts the pipeline joint piece 3, a certain pressure is generated, and the fixing of the pipeline joint piece 3 is realized; meanwhile, the second abutting end 25 abuts the shell cover 26, prevents the fixing block 3 from loosening, and plays the role of positioning and limiting displacement;

[0072] Force transmission and balance: this design makes the fixing block 2 after assembly, the pressure from the shell cover 26 is transmitted to the fixing block 2 through the second abutting end 25, and then transmitted to the pipeline joint piece 3 by the first abutting end 10, so as to form a stable mechanical structure between the fixing block 2, the pipeline joint piece 3 and the shell cover 26, realize the balance and transmission of force.

[0073] In the embodiment of the utility model, the first opening 12 and the second opening 13 which are connected and communicated are respectively arranged along the end face and the side face of the first assembly position 6, the first opening 12 is used for inserting the pipeline joint piece 3 and the fixing block 2, and the second opening 13 is used for allowing the pipeline joint piece 3 and the connecting pipe 4 to be connected.

[0074] On the first assembly position 6 of the shell 1, the first opening 12 is arranged along the end face, and is used for inserting the pipeline joint piece 3 and the fixing block 2, this design makes the pipeline joint piece 3 and the fixing block 2 can be inserted into the first assembly position 6 from a specific position, realizes quick installation and positioning, meanwhile, the size and shape of the first opening 12 are carefully designed, can match the shape of the pipeline joint piece 3 and the fixing block 2, ensure the tightness and stability of the insertion;

[0075] A second opening 13 is formed along the side of the first assembly position 6 and communicates with the first opening 12, which is mainly used for connecting the pipe joint 3 and the connecting pipe 4, and in the pump valve assembly 24, the pipe joint 3 needs to be connected with other components (such as the pump valve assembly 5) through the connecting pipe 4, and the second opening 13 provides space for the connection, so that the connecting pipe 4 can be smoothly led out from the side and connected with other components.

[0076] In the embodiment of the utility model, the fixed block 2 is in U shape or wedge shape.

[0077] For the U-shaped fixed block 2, the walls on both sides can be in contact with the two sides of the pipe joint 3 respectively, forming a surrounding or abutting fixed structure, which can increase the contact area between the fixed block 2 and the pipe joint 3 and improve the stability of the fixing, and at the same time, the bottom of the U-shaped fixed block 2 can be inserted and matched with the first assembly position 6, ensuring the stable position of the fixed block 2 in the shell 1.

[0078] The wedge-shaped fixed block 2 utilizes the characteristics of the inclined surface to generate a certain extrusion force when inserted into the first assembly position 6, thereby achieving more secure fixing, and the wedge-shaped fixed block 2 can be in contact with the pipe joint 3 through the inclined surface, and the pipe joint 3 is tightly fixed in the first assembly position 6 by the pressure of the inclined surface.
