[0034] Breast pumps can be used to express breast milk accumulated in the mammary glands through negative pressure or other methods. Some breast pumps can also be used to temporarily store breast milk. The front of a breast pump is usually equipped with a funnel-shaped breast shield. The surface of the breast shield is roughly adapted to the shape of the breast so that the breast shield fits the user's breast. Breast pumps can also be worn on the body for discreet wearing and immediate storage.
[0035] In some technologies, due to factors such as low temperature, users may not be able to express breast milk smoothly, causing discomfort such as breast engorgement and affecting breast milk secretion. The function of breast pumps is relatively simple and cannot improve the discomfort when expressing breast milk.
[0036] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 To address the aforementioned problems, this application proposes an example of a breast pump. The breast pump includes a main unit 10 and a breast shield 20. The main unit 10 includes a face shell 13 and a massage component 12, with the massage component 12 disposed on the face shell 13. The breast shield 20 includes a first cover 21 and a massage part 22. The first cover 21 is disposed in close contact with the surface of the face shell 13 and is detachably connected to the face shell 13. The massage part 22 is disposed on the first cover 21 and protrudes from the first cover 21. The massage component 12 abuts against the protruding portion of the massage part 22 to massage the human body through the massage part 22.
[0037] The main unit 10 serves as the main structure of the breast pump, allowing the user to hold it and align it with the breast. In some cases, the main unit 10 may also include functional components such as a housing for storing breast milk. The faceplate 13 can be made of hard rubber or other materials. The faceplate 13 can support the breast shield 20.
[0038] The breast shield 20 is connected to the face shell 13. The breast shield 20 can be shaped like a trumpet and can be used to fit onto the user's breast to form a sealed space within a certain range on the breast. The breast shield 20 in this application example can be made of a flexible material; optionally, it can be made of food-grade silicone. The breast shield 20 includes a first cover 21, which can be made entirely of food-grade silicone and can be used to fit onto the user's breast. A massage part 22 is provided on the first cover 21. When the first cover 21 fits onto the user's breast, the massage part 22 can also fit onto the user's breast. The massage part 22 can be integrally formed with the first cover 21, so that the breast shield 20 partially forms a massage area where the first cover 21 fits against the skin surface, providing synchronous massage to the breast. Optionally, the massage part 22 can also be separate from the first cover 21, and the massage part 22 and the first cover 21 at least partially overlap. Optionally, an opening can be provided on the first cover 21, and the massage part 22 can be separately provided from the first cover 21, with the massage part 22 disposed in the opening on the first cover 21 and connected to the first cover 21. The first cover 21 can be detachably connected to the face shell 13, and when the breast pump 20 needs to be cleaned or disinfected, the first cover 21 can be removed separately for cleaning or disinfection. In some examples, the edge of the first cover 21 can cover the edge of the face shell 13 to reduce skin discomfort when the user places the breast pump against the skin. In some examples, the first cover 21 has a first channel 212, which can be used to connect to the functional component on the face shell 13 for storing breast milk. A milk suction channel 213 is formed in the first channel 212, through which breast milk can flow in a preset direction.
[0039] The massage part 22 protrudes from the first cover 21, meaning that the massage part 22 protrudes from the side of the first cover 21 opposite to the face shell 13. When viewed from the side of the first cover 21 opposite to the main unit 10, the massage part 22 can form raised dots on the surface of the first cover 21. In this example, the massage part 22 has a protruding structure, which on the one hand allows space to be provided on the side of the massage part 22 facing the main unit 10 to accommodate the massage component 12; on the other hand, it makes it easier for the massage part 22 to act on the skin surface, improving the massage effect; furthermore, the massage part 22 can have a certain degree of deformation performance, thereby reducing the rigid impact of the massage part 22 on the skin, reducing rigid stimulation to the skin, and improving the comfort of the massage.
[0040] The massage component 12 can move along a preset trajectory under preset conditions, thereby generating vibration. When the breast shield 20 is placed against the user's skin, the massage component 12 can massage the user's skin. The massage component 12 is installed on the main unit 10. When the breast shield 20 is removed from the main unit 10, the massage component 12 is unaffected, and the breast shield 20 can be cleaned separately, thereby reducing the possibility of water ingress and short circuit problems. The massage component 12 abuts against the protruding part of the massage section 22 to massage the human body through the massage section 22.
[0041] In some examples, the massage assembly 12 includes a vibration motor 121 and a motor bracket 122, wherein the motor bracket 122 is used to connect to the face shell 13; the vibration motor 121 is positioned corresponding to the massage part 22, the vibration motor 121 is used to generate vibration, and when the vibration motor 121 vibrates, it can abut against the protrusion of the massage part 22 to massage the human body through the massage part 22.
[0042] In some examples, the main unit 10 also includes a faceplate connector 14 that connects the faceplate 13 and the massage assembly 12. The faceplate connector 14 has elastic recovery properties, and the massage assembly 12 is softly connected to the faceplate 13 through the faceplate connector 14.
[0043] The faceplate connector 14 serves as a connection medium between the massage component 12 and the faceplate 13, allowing the massage component 12 to be connected to the faceplate 13. The faceplate connector 14 possesses elastic recovery properties, meaning it can deform under external force and return to its original shape when the force decreases or disappears. The hardness of the faceplate connector 14 is less than that of the faceplate 13, allowing it a certain degree of deformation. When the massage component 12 is subjected to external force, the faceplate connector 14 can deform relative to the faceplate 13 to a certain extent, thereby reducing the rigid impact of the massage component 12 on the massage part 22. In this example, the faceplate connector 14 can be made of silicone or other materials with deformation properties. The faceplate 13 can be connected and fixed to the faceplate connector 14 by fixed connection, snap-fit, adhesive, or other methods.
[0044] The massage component 12 is softly connected to the face shell 13 via the face shell connector 14. This means that the elastic recovery performance of the face shell connector 14 can be used to allow the massage component 12 to move relative to the face shell 13. The connection between the massage component 12 and the face shell 13 is not a rigid connection, so as to reduce the damage to the face shell 13 caused by the massage component 12 during operation.
[0045] In some examples, a first clearance groove 132 is provided on the face shell 13 at the position corresponding to the massage part 22, the face shell connector 14 is connected to the groove wall of the first clearance groove 132, and the face shell connector 14 is sleeved on the structure of the massage component 12 located in the first clearance groove 132.
[0046] The first clearance groove 132 can be a through groove formed on the face shell 13, and the first clearance groove 132 is used to form a space for installing the face shell connector 14. The number and position of the first clearance grooves 132 correspond to the number of massage parts 22. Each first clearance groove 132 is provided with a face shell connector 14, and a massage component 12 is provided on each face shell connector 14. In this example, the side of the first clearance groove 132 facing the breast shield 20 can have an opening so that the massage component 12 can be connected and fixed to the face shell 13 through the face shell connector 14. At the same time, the massage component 12 is not completely sealed on the face shell 13, thereby reducing the number of isolation parts between the massage component 12 and the massage part 22.
[0047] The faceplate connector 14 is sleeved on the structure of the massage component 12 located in the first relief groove 132. This means that the faceplate connector 14 is at least partially sleeved on the periphery of the massage component 12, and the faceplate connector 14 can block the inner wall surface of the massage component 12 and the first relief groove 132 to reduce the friction between the massage component 12 and the inner wall surface of the first relief groove 132.
[0048] In some examples, the faceplate connector 14 includes a first portion 141, a first pleated portion 143, and a second portion 142. The first portion 141 is annularly fitted around the periphery of the massage assembly 12. The first pleated portion 143 has a first edge and a second edge disposed opposite to each other. The first edge is connected to the first portion 141. The second portion 142 is connected to the second edge of the second pleat and is also connected to the faceplate 13. The massage assembly 12 is connected to at least one of the first portion 141 and the first pleated portion 143.
[0049] The first portion 141 is fitted around the periphery of the massage component 12 so that the first portion 141 can restrict the movement of the massage component 12 from the outer peripheral direction. In this example, the inner wall surface of the first portion 141 can at least partially conform to the outer peripheral surface of the massage component 12.
[0050] The second part 142 is used to connect the face shell 13. The second part 142 can be connected and fixed to the face shell 13 by adhesive, hot melting or other means.
[0051] The first pleated portion 143 is disposed between the first part 141 and the second part 142. The first pleated portion 143 has a pleated shape with uneven texture. When the massage component 12 vibrates, the massage component 12 can drive the first part 141 to move synchronously. At this time, the first pleated portion 143 can provide deformation space for the first part 141 on the one hand, and buffer the massage component 12 on the other hand, so that the massage component 12 can slowly act on the surface of the massage part 22, thereby reducing the rigid impact of the massage component 12 on the massage part 22.
[0052] Please refer to the following: Figure 7 , Figure 8 , Figure 9 as well as Figure 10 In some examples, the breast pump also includes a heating element 101, which is disposed on the faceplate 13. The heating element 101 generates heat and can be made of a heating diaphragm. In some examples, the heating element 101 can be manufactured by combining a heating diaphragm with a flexible printed circuit (FPC) using surface mount technology (SMT). Alternatively, the heating element 101 can be other structures capable of generating heat under preset conditions. Because the heating element 101 is disposed on the faceplate 13, it remains unaffected when the breast shield 20 is removed from the faceplate 13, allowing for separate cleaning of the breast shield 20. This reduces the possibility of short circuits or water ingress in the heating element 101.
[0053] In some examples, the heating element 101 is disposed on the massage assembly 12. The heating element 101 may be integrally formed with the massage assembly 12 to facilitate the assembly of the heating element 101 and the massage assembly 12.
[0054] In some examples, when the heating element 101 is mounted on the massage assembly 12, the massage assembly 12 includes a metal massage head 16 that abuts against the massage section 22. The heating element 101 is connected to the metal massage head 16 to transfer heat to the massage section 22. The metal massage head 16 is used to transfer the heat generated by the heating element 101 to the surface of the massage section 22. The uniformity of the surface temperature of the massage section 22 can be controlled by adjusting the heat exchange area between the metal massage head 16 and the massage section 22, thereby improving the comfort of the breast pump. The metal massage head 16 can be made of a metal sheet.
[0055] In some examples, when the heating element 101 is mounted on the faceplate 13, the heating element 101 is in contact with the surface of the first cover 21. In this example, the heating element 101 is in contact with the surface of the first cover 21 so that the heating element 101 can heat the surface of the first cover 21, thereby improving the comfort of the breast pump; combined with the massage of the massage component 12, it can improve the lactation effect.
[0056] In some examples, the heating element 101 is disposed on the massage assembly 12, and the metal massage head 16 is provided with a first lug 162 on the side opposite to the massage part 22; the massage assembly 12 includes a vibration motor 121 and a motor bracket 122, the first part 141 is annularly sleeved around the periphery of the vibration motor 121; the motor bracket 122 is connected to the vibration motor 121, and the first lug 162 passes through the second part 142 or the first fold 143 and is connected to the motor bracket 122.
[0057] The metal massage head 16 includes a heat conductor 161, which can be the main structure of the metal massage head 16. The heat conductor 161 can be used for heat exchange with the heating element 101 and the massage part 22. In this example, the metal massage head 16 is at least partially attached to the massage part 22 so that the metal massage head 16 can be used to conduct the heat generated by the heating element 101 to the surface of the massage part 22. The metal massage head 16 is provided with a first lug 162, which can be a protruding structure protruding from the surface of the heat conductor 161. The first lug 162 is used to connect the motor bracket 122 so that the entire metal massage head 16 is constrained on the face shell 13, thereby realizing the installation and fixation of the metal massage head 16.
[0058] The motor bracket 122 is used to connect the vibration motor 121 and the first lug 162, with the vibration motor 121 mounted on the motor bracket 122. In this example, a through hole can be provided on the second part 142 or the first fold 143. The first lug 162 passes through the through hole on the second part 142 or the first fold 143 and connects to the motor bracket 122, so that the metal massage head 16, the motor bracket 122, the vibration motor 121, and the faceplate connector 14 form a whole. Since the first lug 162 passes through the second part 142 or the first fold 143, the motor bracket 122 can suspend the first lug 162, connecting the motor bracket 122, the metal massage head 16, and the faceplate connector 14 to each other.
[0059] Please see Figure 10In some examples, the first lug 162 is provided with a positioning hole 163, and the motor bracket 122 is provided with a second lug 123, which is inserted into the positioning hole 163. The positioning hole 163 can be a through hole or a countersunk hole formed on the first lug 162, and the second lug 123 on the motor bracket 122 can be inserted into the positioning hole 163 to fix the first lug 162 and the second lug 123 to each other.
[0060] In some examples, the heat conductor 161 is at least partially cylindrical, with the cylindrical portion of the heat conductor 161 fitted around the periphery of the first portion 141. Multiple first lugs 162 are provided, spaced apart along the circumference of the cylindrical portion of the heat conductor 161, and each of the multiple first lugs 162 is connected to the motor bracket 122. In this example, by providing multiple first lugs 162, they can be adapted to fit the motor bracket 122. Optionally, the motor bracket 122 is provided with multiple second lugs 123, the number of which corresponds one-to-one with the number of first lugs 162, so that the motor bracket 122 and the metal massage head 16 are connected through the cooperation of the multiple first lugs 162 and the second lugs 123.
[0061] In some examples, the faceplate connector 14 has a through hole 144, through which at least part of the heating element 101 extends to the side of the massage assembly 12 facing the massage part 22; the through hole 144 can be a through hole opened on the second part 142 or the first fold 143, and the heating element 101 can pass through the through hole 144 and be laid on the side of the massage assembly 12 facing the massage part 22.
[0062] In some examples, the outer periphery of the vibration motor 121 is provided with a protrusion 1211, which is used to form a protruding area on the outer periphery of the vibration motor 121. The area next to the protrusion 1211 can form a gap with the first part 141. This gap can be used to lay the heating element 101, or to pass the heating element 101 through the gap and lay it on the side of the massage assembly 12 facing the massage part 22.
[0063] In some examples, the massage unit 22 has an inner surface 221 facing the main unit 10 and a side surface 222 surrounding the inner surface 221, so that the massage unit 22 forms a structure protruding outward from the first cover 21; at least a portion of the heating element 101 is disposed between the side surface 222 and the massage assembly 12. In this example, the heating element 101 may be disposed around the massage assembly 12, so that the heating element 101 utilizes the gap between the side surface 222 and the massage assembly 12. Optionally, a metal massage head 16 is disposed between the inner surface 221 and the massage assembly 12, and the metal massage head 16 is disposed in contact with the inner surface 221; the heating element 101 located between the side surface 222 and the massage assembly 12 can conduct heat through the metal massage head 16.
[0064] In some examples, there are multiple massage sections 22, and the main unit 10 is provided with at least one heating element 101 and at least one massage component 12 corresponding to the position of each massage section 22. In this example, the multiple massage sections 22 can be used to massage from different positions to reduce long-term stimulation caused by stimulation of a single point, thereby improving the comfort of the breast pump. In this example, the multiple massage sections 22 can be arranged according to a preset pattern. Optionally, the multiple massage sections 22 can be distributed at intervals around the breast pump channel 213 on the first cover 21. The main unit 10 can be provided with at least one heating element 101 and at least one massage component 12 corresponding to the position of each massage section 22, so that each massage section 22 can achieve both massage and heating effects. Optionally, the main unit 10 can also be provided with multiple heating elements 101 and multiple massage components 12 corresponding to each massage section 22.
[0065] In some examples, there are multiple massage parts 22, which are spaced apart on the breast shield 20. The main unit 10 has a massage component 12 corresponding to the position of each massage part 22, wherein the vibration directions of the massage components 12 corresponding to at least two massage parts 22 are arranged at an angle. In this example, the vibration direction of the massage component 12 can be as follows: Figure 9 In direction 9A shown, the vibration directions of at least two massage units 22 corresponding to the massage components 12 are set at an angle, meaning that the vibration directions of the massage components 12 corresponding to the two massage units 22 are not parallel. In this example, by using massage components 12 with different vibration directions, the massage components 12 can massage from different angles, which can improve the comfort of the breast pump. Optionally, the vibration directions of any two massage components 12 in this example may not be set parallel.
[0066] In some examples, there are multiple massage sections 22 spaced apart on the breast shield 20. The first shield 21 is shaped like a trumpet, concave towards the main unit 10, with at least two massage sections 22 located at different curvatures of the first shield 21. In this example, the trumpet-shaped structure of the first shield 21 allows it to better conform to the breast skin, forming a local seal on the breast surface, thus facilitating the expression of breast milk. By using multiple spaced massage sections 22, the number of massage points can be increased, improving massage comfort. By making the curvatures of the first shield 21 different at at least two massage sections 22, the massage sections 22 can massage from different angles and positions, further enhancing the comfort of the breast pump.
[0067] In some examples, the first cover 21 is provided with a breast suction channel 213, and the number of massage parts 22 is multiple, arranged in a ring around the outer periphery of the breast suction channel 213. In this example, by using massage parts 22 arranged in a ring around the outer periphery of the breast suction channel 213, a ring-shaped massage area can be formed around the outer periphery of the breast suction channel 213, thereby enhancing the massage effect. In this example, the geometric center of the pattern formed by the lines connecting the geometric centers of the multiple massage parts 22 may or may not coincide with the geometric center of the breast suction channel 213.
[0068] In some examples, there are multiple heating elements 101, with at least two heating elements 101 electrically connected. In this example, by electrically connecting at least two heating elements 101, a single power supply can be used to power the two heating elements 101, thereby simplifying the circuit structure.
[0069] Please refer to the following: Figure 6 and Figure 9 In some examples, the breast shield 20 further includes a second pleat 23, through which the first shield body 21 is connected to the massage part 22. The second pleat 23 is disposed on the outer periphery of the massage part 22 and serves to connect the massage part 22 and the first shield body 21. The second pleat 23 can be integrally formed with the first shield body 21, by partially bending the first shield body 21 to form the second pleat 23; alternatively, the second pleat 23 can also be separately formed from the first shield body 21 and connected to it. The second pleat 23 can serve as a seal between the massage part 22 and the first shield body 21, sealing the gap between the outer periphery of the massage part 22 and the first shield body 21. Optionally, the first shield body 21, the second pleat 23, and the massage part 22 can be integrally formed. In this example, by using a second pleat 23 to connect the massage part 22 and the first cover 21, when the massage part 22 moves under the action of the massage component 12, on the one hand, the second pleat 23 can increase the deformation space of the massage part 22 to enhance the massage amplitude of the massage component 12; on the other hand, the second pleat 23 can buffer the instantaneous force of the massage component 12 so that the massage part 22 can act gently on the breast to reduce the rigid impact of the massage part 22 on the body tissue.
[0070] In some examples, the breast shield 20 also includes a second shield 24, which is located on the side of the first shield 21 facing the main unit 10; the second shield 24 has a second relief groove 242 at the position corresponding to the massage part 22; the first shield 21 has a first channel portion 212 protruding towards the main unit 10, and the second shield 24 has a second channel portion 241 protruding towards the main unit 10, wherein the first channel portion 212 is at least partially inserted into the second channel portion 241.
[0071] The second cover 24 forms a supporting and thickening structure on the side of the first cover 21 facing the main unit 10, thereby improving the structural strength of the first cover 21. A second clearance groove 242 is provided on the second cover 24, corresponding to the position of the massage part 22, so that the massage component 12 and the first heating element 101 can act on the surface of the massage part 22 via the second clearance groove 242. In this example, the second clearance groove 242 can be a through groove penetrating the surface of the second cover 24, forming a space for installing the first heating element 101 and the massage component 12. The first cover 21 has a first channel portion 212 protruding towards the main unit 10, within which a breast-suction channel 213 can be formed. The second cover 24 has a second channel portion 241 protruding towards the main unit 10, with the first channel portion 212 at least partially inserted into the second channel portion 241, so that the second channel portion 241 can support and reinforce the first channel portion 212.
[0072] In this example, the first cover 21 and the second cover 24 can be made of the same material. Optionally, the first cover 21 and the second cover 24 can be made of different materials. In some examples, the hardness of the second cover 24 is not less than that of the first cover 21, so that the second cover 24 can be used to support the first cover 21. In this example, the first cover 21 is made of food-grade silicone, and the second cover 24 can be made of silicone with a hardness greater than that of food-grade silicone. By limiting the hardness relationship between the first cover 21 and the second cover 24 in this example, the second cover 24 can support the first cover 21. On the one hand, this allows the first cover 21 to maintain its preset shape; on the other hand, it facilitates the removal of the breast shield 20 for cleaning.
[0073] Please refer to the following: Figure 7 and Figure 9 In some examples, the first cover 21 is provided with a first guide portion 211, and the second cover 24 is provided with a second guide portion 243. The first guide portion 211 and the second guide portion 243 are guided and engaged. The guiding engagement means that the first guide portion 211 and the second guide portion 243 can be connected to each other along a preset trajectory so that the first cover 21 and the second cover 24 cannot move in a direction that is at an angle to the preset trajectory. For example, the first guide portion 211 can be a protrusion on the first cover 21, and the second guide portion 243 can be a structure with a groove. The first guide portion 211 can be guided and engaged with the second guide portion 243 by plugging in.
[0074] Please see Figure 7In some examples, one of the second cover 24 and the main unit 10 is provided with a positioning groove 244, and the other is provided with a positioning bead 17. The positioning bead 17 is used to engage with the positioning groove 244 when the second cover 24 is installed on the main unit 10. The positioning bead 17 can cooperate with the positioning groove 244. When the second cover 24 is installed on the main unit 10, the positioning bead 17 can restrict the movement of the second cover 24, thereby reducing the possibility of the breast shield 20 falling off the main unit 10. In this example, the positioning bead 17 can be a structure such as an elastic button on the main unit 10. When the second cover 24 is installed on the main unit 10, the second cover 24 can squeeze the positioning bead 17, causing the positioning bead 17 to deform. When the positioning bead 17 moves to the position of the positioning groove 244, the positioning bead 17 elastically returns to its original position, and the positioning bead 17 can prevent the second cover 24 from falling off the main unit 10.
[0075] In some examples, the massage unit 22 has an inner surface 221 facing the main unit 10 and a side surface 222 surrounding the inner surface 221; wherein at least a portion of the heating element 101 is disposed between the inner surface 221 and the massage assembly 12; the heating element 101 located between the inner surface 221 and the massage assembly 12 can be used to heat the inner surface 221 of the massage unit 22, thereby increasing the surface temperature of the massage unit 22. In this example, on the one hand, the heat exchange area between the heating element 101 and the surface of the massage unit 22 can be increased, and on the other hand, the heating element 101 and the massage assembly 12 can be stacked, thereby making full use of the space between the massage assembly 12 and the inner surface 221 of the massage unit 22.
[0076] In some examples, the massage unit 22 has an inner surface 221 facing the main unit 10 and a side surface 222 surrounding the inner surface 221; the heating element 101 is at least partially located between the massage assembly 12 and the inner surface 221, and the heating element 101 is spaced apart from the massage assembly 12; in order to reduce the direct impact of the massage assembly 12 on the heating element 101 and reduce the possibility of damage to the heating element 101.
[0077] In some examples, the massage part 22 has an inner surface 221 facing the main unit 10 and a side surface 222 surrounding the inner surface 221; the heating element 101 is at least partially located between the massage assembly 12 and the inner surface 221, and a metal massage head 16 is disposed between the inner surface 221 and the heating element 101, the metal massage head 16 being disposed in contact with the inner surface 221; the metal massage head 16 is used to transfer the heat generated by the heating element 101 to the surface of the massage part 22, and the uniformity of the surface temperature of the massage part 22 can be controlled by controlling the heat exchange area between the metal massage head 16 and the massage part 22, thereby improving the comfort of the breast pump.
[0078] In some examples, the first cover 21 has a first channel portion 212 protruding toward the main unit 10. The main unit 10 includes a face shell 13 and a face shell connector 14. The breast shield 20 is connected to the face shell 13. The heating element 101 and the massage component 12 are both mounted on the face shell 13. The face shell 13 has a third channel portion 131. The first channel portion 212 is at least partially inserted into the third channel portion 131. The massage component 12 is connected to the face shell 13 through the face shell connector 14, wherein the hardness of the face shell connector 14 is less than the hardness of the face shell 13.
[0079] A breastfeeding channel 213 can be formed within the first channel portion 212. The first cover 21 is connected to the face shell 13. In this example, the edge of the first cover 21 can wrap around the edge of the face shell 13. The face shell 13 has a third channel portion 131, which can be fitted onto the outside of the first channel portion 212. The first channel portion 212 is inserted into the third channel portion 131, so that the face shell 13 can support and limit the first channel portion 212.
[0080] In some examples, the thickness of the massage part 22 is less than the thickness of the first cover 21, so that when the massage component 12 vibrates, it can act on the massage part 22, and the massage part 22 can have a greater deformation range under the force, thereby improving the massage effect.
[0081] In some examples, the thickness of the massage part 22 is not less than 0.5 mm and not more than 0.8 mm. In this application example, by reasonably limiting the thickness of the massage part 22, the problem of breakage due to excessive thickness of the massage part 22 can be reduced, and the problem of reduced massage effect due to excessive thickness of the massage part 22 can be reduced. The thickness of the massage part 22 in this example can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, or any other value within the above range.
[0082] In some examples, a cushioning layer 124 is provided on the side of the massage assembly 12 facing away from the massage part 22. The cushioning layer 124 is used to form a protective layer on the massage assembly 12 to reduce the possibility of damage to the side of the massage assembly 12 facing away from the massage part 22.
[0083] Please see Figure 7In some examples, the surface of the faceplate 13 opposite to the breast shield 20 is provided with multiple limiting grooves 133. The multiple limiting grooves 133 are respectively provided with multiple intermediate connectors 145, and the multiple intermediate connectors 145 are respectively embedded in the corresponding limiting grooves 133 one by one. The number and position of the limiting grooves 133 correspond to the number and position of the intermediate connectors 145. When the fixing part 146 is fitted on the third channel part 131, the limiting grooves 133 can limit each intermediate connector 145. On the one hand, it can prevent each intermediate connector 145 from moving along the circumference of the fixing part 146, and on the other hand, it can prevent the intermediate connectors 145 from protruding on the surface of the faceplate 13, thus reducing the space occupied by the intermediate connectors 145.
[0084] In some examples, the breast shield 20 has a second guide portion 243 on the side facing the face shell 13, and a third guide portion 134 is provided on the face shell 13. The second guide portion 243 and the third guide portion 134 are guidedly connected. The guide connection between the second guide portion 243 and the third guide portion 134 means that the second guide portion 243 and the third guide portion 134 can move along a preset trajectory, but the face shell 13 and the breast shield 20 cannot move along a direction that is angled to the preset trajectory. The second guide portion 243 and the third guide portion 134 are used to cooperate with each other to restrict the relative rotation of the face shell 13 and the breast shield 20. Optionally, in this example, the third guide portion 134 can be provided on the third channel portion 131, the breast shield 20 can include the first cover body 21 and the second cover body 24 in any of the above examples, and the second guide portion 243 can be provided on the second channel portion 241.
[0085] In some examples, there are multiple massage components 12 and massage parts 22, with multiple massage components 12 spaced apart on the main unit 10. The heating element 101 includes a first heating element 11 and a second heating element 15. The first heating element 11 is disposed on the massage component 12, and the second heating element 15 is disposed between at least two adjacent massage components 12.
[0086] The second heating element 15 can be installed on the main unit 10 or on the breast shield 20, such as... Figure 11 The second heating element 15 shown is merely a schematic representation of its position from this perspective and does not imply that the second heating element 15 can only be installed on the surface of the breast pump 20 facing away from the main unit 10. In this example, the second heating element 15 can be used to heat between two adjacent massage sections 22 to form at least one heating zone on the breast pump 20, thereby enhancing the heating effect of the breast pump.
[0087] In some examples, there are multiple second heating elements 15, which are spaced apart along the lines connecting the multiple massage sections 22. In this example, by providing multiple second heating elements 15, heating can be applied from multiple areas, further enhancing the heating effect of the breast pump. The multiple second heating elements 15 are positioned along the lines connecting the geometric centers of the multiple massage sections 22, allowing them to work in conjunction with the massage sections 22 to enhance the comfort of the breast pump. In this example, the multiple second heating elements 15 can be independently positioned relative to the first heating element 11. This allows for the convenient and independent formation of multiple heating zones as needed, and also makes full use of materials such as heating films, reducing material waste.
[0088] The above are merely embodiments of this application and do not limit the scope of this patent application. Any equivalent structural or procedural changes made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
