[0032] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0034] The terms "system", "unit" and "network" are often used interchangeably in this article. The term "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship. In addition, "many" in this article means two or more than two.

[0035] In one aspect of the present application, a breast pump is provided. Figure 1 , Figure 1 It is a structural schematic diagram of an embodiment of the milk suction part of the breast pump provided by the present application. The milk suction part of the breast pump comprises a soft rubber cover body 1 and a heating element 2, wherein the soft rubber cover body 1 comprises a fluid channel 14, wherein the texture of the soft rubber cover body 1 is smoother, has good hydrophilicity, and is easier to fit the skin. The heating element 2 comprises a main body 21 and a connecting part 22 formed by extending the main body 21, and the connecting part 22 is provided with a plug-in interface 221, which is used for an external power supply (not shown) to electrically heat the milk suction part. The outer wall of the soft rubber cover body 1 away from the fluid channel 14 is provided with a mounting hole 13, and the main body 21 is arranged in the soft rubber cover body 1, and the main body 21 is a platform, and the main body 21 is adapted to the soft rubber cover body 1, that is, a 3D conical surface structure, which ensures that the heating element 2 can be completely fitted with the soft rubber cover body 1, and the heating capacity of the entire milk suction part is enhanced while ensuring that the heat can be fed back to the mother in time. It is understandable that the main body 21 can also be set in a prism shape, as long as the main body 21 can adapt to the soft rubber cover body 1, and the heating element 2 can fit the soft rubber cover body 1, the main body 21 can be set in a desired shape according to the actual needs of the milk sucking part without affecting the overall heating effect of the milk sucking part. The connecting part 22 is set in the mounting hole 13, and the plug-in interface 221 is exposed to the soft rubber cover body 1 through the mounting hole 13, so that the milk sucking part of the breast pump can be connected to an external power supply and the breast pump can be continuously heated or kept warm by the heating element 2. The soft rubber cover body 1 is integrally formed with the heating element 2 during the injection molding process, so that the heating element 2 and the entire soft rubber cover body 1 are more closely fitted, and the heat of the heating element 2 can also be transmitted to the position where the soft rubber cover body 1 fits the mother body with less loss.

[0036] For further information, please refer to Figure 4 , Figure 4 yes Figure 1Schematic diagram of the structure of the heating element. In some embodiments, the main body 21 is formed by connecting the sides of a curved heating plate (not shown) end to end. In order to ensure the stability of its fixation, the main body 21 and the connecting part 22 are both provided with through holes 210. When the soft rubber cover body 1 and the heating element 2 are co-injected, the through holes 210 are filled with injection sol, which further ensures the tightness of the fixation between the soft rubber cover body 1 and the heating element 2. A fixing plate 20 is provided at the interface of the heating plate to fix the shape of the heating element 2, which ensures the stability of the three-dimensional structure of the heating element 2 and the use effect of the breast pump of the breast pump.

[0037] In other embodiments, the main body 21 is formed by pressing an annular heating plate, and a conical structure is formed directly by pressing. The conical structure has the same curvature as the soft rubber cover body 1. In this case, there is no need to process the heating element 2 separately. The heating element 2 is directly connected to the soft rubber cover body 1 and tightly connected through injection molding to form the milk suction part of the breast pump.

[0038] Please continue to refer to Figure 1 In some embodiments, the soft-gel cover body 1 includes a first sub-cover body 11 and a second sub-cover body 12, which are fixedly connected by injection molding, and the heating element 2 can be accommodated in the soft-gel cover body 1 without affecting the overall airtightness of the soft-gel cover body 1. The main body 21 is arranged between the first sub-cover body 11 and the second sub-cover body 12, which can achieve uniform heating of the soft-gel cover body 1, further improving the heating feel of the breast pump of the breast pump.

[0039] Specifically, in order to ensure that the milk suction part of the breast pump reaches the appropriate temperature during heating and can be powered off or kept warm in time, please refer to Figure 1 and Figure 4 In some embodiments, a temperature sensor 15 is provided on either the soft rubber cover body 1 or the main body 21 to detect the temperature of the entire heating element 2, thereby ensuring effective heating temperature and avoiding overheating. A fixing member (not shown) is provided on one end of the temperature sensor 15 away from the heating element 2 to ensure that the temperature sensor 15 can still be stably fixed in the original position when the heating element 2 is bent.

[0040] Furthermore, a protective ring (not shown) is provided at the other end of the temperature sensor 15. The protective ring and the fixing parts work together at both ends of the temperature sensor 15 to further stabilize the position of the temperature sensor 15, thereby ensuring the stability of the heated temperature of the milk suction part of the breast pump and avoiding burns to the mother due to excessive temperature during use.

[0041] Please refer to Figure 2 and Figure 3 , Figure 2 yes Figure 1 A schematic diagram of a partial cross-sectional structure of a milk suction part of the breast pump described in the figure; Figure 3 yes Figure 2 Schematic diagram of the enlarged structure of circle A in the milking part of the breast pump described in the figure. In some embodiments, the plug interface 221 includes a socket 2211, which is arranged in the mounting hole 13 to connect the heating element 2 through the soft rubber cover body 1 to the external power supply to achieve heating. The connecting part 22 is provided with a contact 220 and a stud 222, and the stud 222 is used to accommodate the fixing screw. The socket 2211 is sleeved on the stud 222, and the contact 220 is accommodated in the socket 2211 to avoid the contact 220 from contacting the injection sol during injection molding, which affects its sensitivity and further affects the heating degree of the milking part. Among them, the contacts 220 are respectively the positive and negative electrodes of the heating element 2 and the positive and negative electrodes of the temperature sensor 15.

[0042] It can be understood that a glue groove (not shown) is provided at the contact position between the power plug interface 221 and the soft rubber cover body 1, so that when the soft rubber cover body 1 is injection molded, the glue groove on the power plug interface 221 also accommodates the injection sol, thereby increasing the contact area between the soft rubber cover body 1 and the power plug interface 221, and further ensuring the structural stability of the milk suction part of the entire breast pump.

[0043] Furthermore, the plug interface 221 also includes a plug cover plate 2212, which is used as a medium for connecting an external power source. The plug cover plate 2212 covers the socket 2211, and is provided with a fixing hole. The fixing screw passes through the fixing hole and the stud 222 to fix the plug cover plate 2212 on the plug interface 221, thereby avoiding the disconnection or short circuit caused by the unstable connection between the plug interface 221 and the plug cover plate 2212 when connecting an external power source through the plug cover plate 2212, and further avoiding the occurrence of dangerous situations. A spring pin 22120 is also provided on the plug cover 2212, and the plug socket 2211 is accommodated in the mounting hole 13. The spring pin 22120 passes through the mounting hole 13 and the plug socket 2211 abuts against the contact 220, thereby realizing the connection between the plug cover 2212 and the heating element 2, ensuring the stability of the current and heating conditions of the heating element 2 when an external power source is connected, further enhancing the user experience of the heating mode of the breast pump part of the breast pump.

[0044] It can be understood that a contact reinforcement plate (not shown) is provided around the contact 220. When the spring pin 22120 is fixed to the contact 220, it abuts against the contact reinforcement plate to prevent the contact area between the contact 220 and the spring pin 22120 from being too small. When the breast pump shakes or moves, the spring pin 22120 is separated from the contact position of the contact 220, resulting in poor contact.

[0045] The plug cover 2212 and the plug socket 2211 can also be fixed by a series of combination methods such as gluing, buckling, ultrasound, etc. A sealing member 23 can also be provided at the connection between the plug cover 2212 and the plug socket 2211 to prevent water from entering the inside of the breast pump through the connection gap when the breast pump is cleaned, thereby affecting its normal operation.

[0046] Another aspect of the present application provides a method for manufacturing a breast pump part of a breast pump, please refer to Figure 5 , Figure 5 1 is a flow chart of an embodiment of a method for manufacturing a milk suction part of a breast pump provided by the present application. The manufacturing method specifically comprises:

[0047] Step S1: Injection molding forms the first sub-cover body 11, and the first sub-cover body 11 is retained in the first sub-cover body mold after the mold is opened. When the entire breast pump is injection molded, the first sub-cover body mold is injected with injection sol, and the mold is processed. When the first sub-cover body 11 reaches the desired state, the first sub-cover body 11 is demoulded for standby use.

[0048] The first sub-cover body mold can be divided into an upper operating position and a lower operating position. When the first sub-cover body mold is injection-molded, the upper operating position and the lower operating position are combined and injection molding is performed therein. When the first sub-cover body 11 reaches a desired state, the first sub-cover body 11 is demoulded from the upper operating position, and part of the first sub-cover body 11 is retained in the lower operating position for standby use.

[0049] Step S2: Obtain the heating element 2, and place the heating element 2 at a preset position of the first sub-cover body 11 to obtain a pre-molding mold. The formed heating element 2 is placed at a preset position on the first sub-cover body 11, so that the heating element 2 and the soft rubber cover body 1 are placed in close contact, so that the heating effect of the breast pump is more uniform and the use experience is improved. By placing the heating element 2 on the first sub-cover body 11, the heating element 2 is also accommodated in the lower operating position of the first sub-cover body mold, and a pre-molding mold is formed.

[0050] Step S3: Injection molding forms the second sub-cover body 12, and the second sub-cover body 12 is retained in the second sub-cover body mold after the mold is opened. When the entire breast pump is injection molded, the second sub-cover body mold is injected with injection sol, and the mold is processed. When the second sub-cover body 12 reaches the desired state, the second sub-cover body 12 is demoulded for standby use.

[0051] The second sub-cover body mold can also be divided into an upper operating position and a lower operating position. When the second sub-cover body mold is injection-molded, the upper operating position and the lower operating position are combined and injection molding is performed therein. When the second sub-cover body 12 reaches the desired state, the second sub-cover body 12 is demoulded from the lower operating position, and part of the second sub-cover body 12 is retained in the upper operating position for standby use.

[0052] Furthermore, in some implementation scenarios, while the first sub-cover body 11 is being injection molded, the second sub-cover body 12 is also being injection molded simultaneously, thereby reducing the time cost of processing.

[0053] It is understandable that there is no order between the above steps S1 and S3 , and the first sub-cover body 11 and the second sub-cover body 12 can be formed simultaneously, or step S1 or step S3 can be performed first according to needs.

[0054] Step S4: close the pre-mold mold and the second sub-cover mold. In some implementation scenarios, after the first sub-cover 11 and the second sub-cover 12 are formed, the lower operating position of the first sub-cover mold and the upper operating position of the second sub-cover mold are closed, and the process is continued until the breast pump structure is completely formed, cooled and demolded.

[0055] Step S5: demoulding to obtain the breast pumping part of the breast pump. At this time, the breast pumping part of the breast pump after demoulding is made of soft rubber material with a heating element, which needs to be assembled with other structures of the breast pump to form a complete breast pump.

[0056] In order to ensure that the heating element 2 does not deviate when it is placed at the preset position of the first sub-cover body 11, the first sub-cover body 11 needs to be kept in a semi-cooked state during injection molding. Figure 6 , Figure 6 yes Figure 5 The above step S1 specifically includes:

[0057] Step S11: injecting plastisol into the first sub-cover body mold. In some specific implementation scenarios, the first sub-cover body mold is injected with a plastisol made of a soft plastic material, which has a certain elasticity, better fluidity, and is more suitable for skin.

[0058] Step S12: Obtain the socket 22111 and place the socket 2211 at a preset position. In some implementation scenarios, before the first sub-cover body 11 is formed, a connection point where the heating element 2 is connected to the external power supply is reserved, namely the socket 2211. The mold of the socket 2211 is placed at a suitable position in the mold of the first sub-cover body and kept fixed.

[0059] In addition, in some other implementation scenarios, the first sub-cover body mold can also be directly set to have the shape of the socket 2211 mold, and the socket 2211 and the first sub-cover body 11 can be integrally formed by injection molding through a separate first sub-cover body mold, thereby reducing the molding steps of the first sub-cover body 11, simplifying manual operations, and reducing labor costs.

[0060] Step S13: Heat the first sub-cover mold to 170-200 degrees and maintain it for 3-7 seconds. In this implementation scenario, the first sub-cover 11 is in a semi-cooked state of the injection molding sol. The first sub-cover mold can be heated to 170 degrees, 180 degrees, 190 degrees, 200 degrees, and maintained for a suitable time accordingly, for example, 3 seconds, 5 seconds, 7 seconds, etc. At this time, the first sub-cover 11 has a certain hardness and still has a certain fluidity, which can ensure that the heating element 2 can still be centered between the first sub-cover 11 and the second sub-cover 12 to avoid deviation.

[0061] Most preferably, the first sub-cover body mold is heated to 190 degrees and maintained for 5 seconds, so that the first sub-cover body 11 can be maintained in a semi-cooked state.

[0062] In some other implementation scenarios, please refer to Figure 7 , Figure 7 yes Figure 5 The injection molding of the first sub-cover body 11 may also be performed using other steps:

[0063] Step S130: Heat the first sub-cover body mold to 170-200 degrees and maintain it for 350-450 seconds. In this implementation scenario, when a structure that can fix the heating element 2 is provided in the first sub-cover body mold, the first sub-cover body 11 can be directly heated to a fully cooked state to stabilize its state. Specifically, the first sub-cover body mold can be heated to 170 degrees, 180 degrees, 190 degrees, 200 degrees, and maintained for a suitable time accordingly, for example, it can be maintained for 350 seconds, 370 seconds, 390 seconds, 400 seconds, 420 seconds, 440 seconds or 450 seconds, etc. The stability of the heating element 2 is ensured by a fixed structure when the first sub-cover body mold and the second sub-cover body mold are molded together.

[0064] Most preferably, the first sub-cover body mold is heated to 190 degrees and maintained for 400 seconds, so that the first sub-cover body 11 can be maintained in a stable state.

[0065] Step S14: Open the mold to form the first sub-cover 11. In this implementation scenario, after the first sub-cover 11 is formed or reaches a desired state, the upper operating position of the first sub-cover mold is moved away from the first sub-cover mold, and the first sub-cover 11 is accommodated in the lower operating position.

[0066] In order to better ensure that the heating element 2 can fit tightly with the soft rubber cover body 1, the heating element 2 can be bent or pre-set first, please refer to Figure 8 , Figure 8 yes Figure 5 The above step S2 specifically includes:

[0067] Step S21: Obtain a heating plate with a curved through hole, and connect the heating plate end to end to form a trumpet shape. In this implementation scenario, the heating plate is fan-shaped, and a trumpet-shaped cone-like surface is formed by connecting the busbars of the heating plate end to end, and the trumpet-shaped heating plate is placed on the first sub-cover body 11. It can be understood that in order to further ensure the degree of fit between the heating element 2 and the first sub-cover body 11, the central angle of the heating plate should be the same as the central angle of the soft rubber cover body 1.

[0068] It is understandable that in some embodiments, the heating plate can be made of metal or non-metal, and a suitable heating plate material can be selected according to the temperature design requirements and actual design structure of different breast shields to meet a variety of different usage requirements.

[0069] Step S22: A fixing plate 20 is fixedly arranged at the end where the heating plate is connected to form a heating element 2. In this implementation scenario, since the temperature required is high and the maintenance time is long when the first sub-cover 11 and the second sub-cover 12 are molded together, melting may occur under a long high temperature adjustment regardless of whether the heating plate is welded end to end or connected by other fixings, so a fixing plate 20 is arranged at the end where the heating plate is connected, and the fixing plate 20 is fixed to the heating element 2 by fastening bolts, which further enhances the stability of the heating element 2.

[0070] In some other implementation scenarios, please refer to Fig. 9 , Fig. 9 yes Figure 5 The process diagram of another embodiment of step S2 described in FIG. Other steps may also be used to obtain the heating element 2:

[0071] Step S21': Obtain a pressed annular heating plate with a through hole to form a heating element. The heating element 2 can be directly pressed into a conical structure with the same curvature as the soft rubber cover body 1, further saving installation steps and improving installation efficiency.

[0072] Step S23: Place the heating element 2 at a preset position of the first sub-cover body 11 to form a preset mold. The heating element 2, which is bent and has the same curvature as the first sub-cover body 11, is placed in a close relationship with the first sub-cover body 11 to form a preset mold for standby use. Similarly, when the second sub-cover body 12 is formed by injection molding, in order to ensure that the first sub-cover body 11 and the second sub-cover body 12 can be completely fitted in the mold, the second sub-cover body 12 is usually also formed in a semi-cooked state. Please refer to Fig.10 , Fig.10 yes Figure 5 The flowchart of the embodiment of step S3 described in the figure is as follows. Step S3 specifically includes:

[0073] Step S31: injecting plastisol into the second sub-cover mold. In some specific implementation scenarios, the plastisol made of soft glue is injected into the second sub-cover mold. In order to ensure that the first sub-cover 11 and the second sub-cover 12 can be completely fused and attached, the first sub-cover 11 and the second sub-cover 12 should be made of the same material.

[0074] Step S32: Heat the second sub-cover body mold to 170-200 degrees and maintain for 3-7 seconds. In this implementation scenario, the second sub-cover body 12 is in a semi-cooked state of the injection molding sol. At this time, the second sub-cover body 12 has a certain hardness and still has a certain fluidity. Specifically, the first sub-cover body mold can be heated to 170 degrees, 180 degrees, 190 degrees, 200 degrees, and maintained for a suitable time accordingly, for example, it can be maintained for 3 seconds, 5 seconds, 7 seconds, etc. When the lower operating position of the second sub-cover body mold is moved away, the second sub-cover body 12 can still remain in the upper operating position of the second sub-cover body mold and has a certain stability.

[0075] Most preferably, the second sub-cover body mold is heated to 190 degrees and maintained at this temperature for 5 seconds, so that the second sub-cover body 12 can be maintained in a stable state.

[0076] Step S33: Open the mold to form the second sub-cover body 12. At this time, the second sub-cover body 12 is located at the upper operating position of the second sub-cover body mold, waiting to be molded with the first sub-cover body 11 to form the overall structure of the breast pump.

[0077] Please refer to Fig.11 , Fig.11 yes Figure 5 The above step S4 specifically includes:

[0078] Step S41: The pre-molding mold and the second sub-cover mold are molded together to form a breast pump forming mold. In this implementation scenario, the pre-molding mold where the first sub-cover 11 is located and the second sub-cover mold where the second sub-cover 12 is located are set at the same station through operation. After the two are molded together, the first sub-cover 11 and the second sub-cover 12 are fixed together.

[0079] Step S42: Raise the temperature of the breast pump molding mold to 170-200 degrees and maintain it for 350-450 seconds until the injection sol is fully matured. When the first sub-cover body 11 and the second sub-cover body 12 are molded together, they need to be fused and connected. Specifically, the first sub-cover body mold and the second sub-cover body mold can be heated to 170 degrees, 180 degrees, 190 degrees, 200 degrees, and maintained for a suitable time accordingly, for example, 350 seconds, 370 seconds, 390 seconds, 400 seconds, 420 seconds, 440 seconds or 450 seconds, etc. At least the edge areas of the first sub-cover body 11 and the second sub-cover body 12 need to be melted to connect them together, so that the entire soft rubber cover body 1 is formed as a whole.

[0080] Most preferably, the first sub-cover body mold and the second sub-cover body mold are heated to 190 degrees and maintained for 400 seconds, so that the formed soft rubber cover body 1 can be maintained in a stable state.

[0081] In some implementation scenarios, after the injection molding of the breast pump, the medium connected to the external power supply needs to be assembled on the breast pump. Fig.12 , Fig.12 yes Figure 5 The flowchart of the embodiment of step S5 described in the embodiment of FIG. 1 is as follows. The step S5 specifically includes:

[0082] Step S51: After the milk sucking piece forming mold is cooled and shaped, demoulding is performed. After the first sub-cover body 11 and the second sub-cover body 12 are molded together, the soft rubber cover body 1 formed by the first sub-cover body 11 and the second sub-cover body 12 is completely cooled and shaped, and then demoulding is performed to obtain the injection molded milk sucking piece structure.

[0083] Step S52: Get the plug cover 2212, install the plug cover 2212 on the socket 2211, and get the milk suction part of the breast pump. In this implementation scenario, the plug cover 2212 covers the socket 2211, and the plug cover 2212 is fastened to the socket 2211 by fixing screws, so as to avoid the poor contact between the plug cover 2212 and the socket 2211, which may cause the milk suction part to be unstable in connection with the external power supply and affect the use experience.
