[0027] This embodiment provides a breast pump to avoid the problem that a separate heating system needs to be added to the breast pump, which will increase the cost and cause waste of resources.

[0028] As Figure 1As shown in the figure, the breast pump includes a main body 1 and a main unit 2. The main unit 2 is connected to the main body 1. The main unit 2 is used to generate negative pressure inside the main body 1. The main body 1 has a shield 11. The shield 11 is used to contact the breast. When negative pressure is generated inside the main body 1, milk can be sucked through the shield 11. Exemplarily, the main unit 2 at least includes a vacuum generator, and the vacuum generator can generate negative pressure in the main body. It should be noted that the specific structure and working principle of the vacuum generator can be referred to the prior art, and will not be elaborated in this embodiment.

[0029] Specifically, as Figure 1 and Figure 4 shown, the breast pump further includes a heating component 3. The heating component 3 is arranged on the main unit 2 and is electrically connected to the main unit 2, so that the main unit 2 can supply electrical energy to the heating component 3. The heating component 3 includes a heating surface (not shown in the figure). The heating surface can contact the inner wall of the shield 11 to heat the shield 11, so that the temperature of the shield 11 rises, and further the temperature difference between the shield 11 and the breast is smaller.

[0030] When using the breast pump provided in this embodiment, as Figure 3 shown, before the breast pump performs the milk sucking operation, first contact the heating surface of the heating component 3 with the inner wall of the shield 11 to heat the shield 11, so as to ensure that in low temperature weather, the shield 11 does not affect the user's physical feeling and ensure the normal secretion of breast milk.

[0031] For the breast pump provided in this embodiment, the main unit 2 is connected to the main body 1 and is used to generate negative pressure inside the main body 1. The main body 1 has a shield 11. The breast pump further includes a heating component 3. The heating component 3 is arranged on the main unit 2 and is electrically connected to the main unit 2. The heating component 3 includes a heating surface, and the heating surface can contact the inner wall of the shield 11 to heat the shield 11. During use, first use the heating component 3 to heat the inner wall of the shield 11, and then start milk sucking after heating, which avoids an additional heating system, saves costs, avoids waste, and improves the portability of the breast pump and reduces the volume of the breast pump.

[0032] Furthermore, the main body 1 further includes a main body body (not shown in the figure), and the shield 11 is detachably connected to the main body body. With this setting, for different users, different sizes and types of shields 11 can be replaced, with high adaptability. In addition, it is also convenient to clean the shield 11 and convenient to use. In this embodiment, the main unit is connected to the main body body and is used to generate negative pressure inside the main body body.

[0033] Furthermore, the inner wall of the shield 11 is provided with silicone. It can be understood that: the silicone material is soft and is convenient to fit the user's skin, which is beneficial to improving the user's comfort; in addition, silicone has a certain heat preservation effect, which is beneficial to reducing the cooling speed of the shield 11 and improving the user's comfort.

[0034] Optionally, as shown in Figure 1 the breast pump further includes a milk bottle 12 which is internally connected to the main body 1 and detachably connected to the main body 1 for storing breast milk.

[0035] Optionally, as shown in Figure 1 and Figure 4 the heating component 3 includes a heating film (not shown in the figure). The heating film is disposed on the main unit 2 and electrically connected to the main unit 2, and the heating surface is the surface of the heating film. It can be understood that by providing a heating film electrically connected to the main unit 2, the main unit 2 can supply electrical energy to the heating film for heating the heating film, and there is no need to provide an additional power source.

[0036] Exemplarily, the heating film can be divided into a low-temperature heating film and a high-temperature heating film. Among them, the high-temperature electrothermal film is generally used in electronics, military, etc. The heating film in this embodiment is a low-temperature heating film, and the heating temperature will not be too high to avoid damaging the shield 11. The low-temperature electrothermal film is a translucent polyester film that can generate heat after being energized. It is made by processing and thermocompression of a special conductive ink and a metal current-carrying strip between insulating polyester films. When working, the heating film is used as a heating element, and the heat is sent to the inner wall of the shield 11 in the form of radiation to increase the temperature of the shield 11.

[0037] Furthermore, both the heating surface and the shield 11 are in a horn shape. It can be understood that the main body 1 has a horn-shaped shield 11, and the heating component 3 includes a horn-shaped heating surface. The shapes of the heating surface and the shield 11 are the same, which is convenient for the two to fit together, thereby improving the heating effect of the heating component 3 on the shield 11.

[0038] In other alternative embodiments, the heating surface and the shield 11 can be of other shapes, and this embodiment does not limit this.

[0039] Furthermore, to improve the installation convenience of the heating component 3, the heating component 3 is magnetically connected to the main unit 2, that is, by respectively providing magnets with different magnetic properties on the heating component 3 and the main unit 2 for connecting the two, it is convenient for the assembly and disassembly of the heating component 3 and the main unit 2, and has high convenience.

[0040] Or, the heating component 3 is adhesively connected to the main unit 2, that is, a viscous material is provided at the position where the heating component 3 contacts the main unit 2 for connection, such as glue or double-sided tape, etc.

[0041] Or, the heating component 3 is snap-connected to the main unit 2, that is, structures that can be snap-connected to each other are respectively provided on the heating component 3 and the main unit 2, such as a snap and a slot cooperation and other snap connection structures, which are convenient for the assembly and disassembly of the heating component 3 and the main unit 2, and have high convenience.

[0042] In other alternative embodiments, the heating component 3 can also be limited on the main body 2 by a limiting structure, and this embodiment does not limit this.

[0043] Optionally, the main body 2 includes a housing (not shown in the figure). A part of the housing constitutes a part of the heating component 3, and the outer surface of the housing constitutes the heating surface of the heating component 3. It can be understood that directly using a part of the structure of the housing to form a part of the structure of the heating component 3 in this embodiment can reduce the cost of separately providing a complete heating component 3, reduce the connection process between the heating component 3 and the main body 2, avoid the situation of connection failure between the heating component 3 and the main body 2, and facilitate the electrical connection between the heating component 3 and the main body 2 to ensure the stability of heating the breast pump shield 11. It also realizes the multiple uses of the housing and enriches the functions of the housing.

[0044] In some alternative embodiments, the housing is provided with a sandwich layer, and the heating component 3 can be arranged in the sandwich layer. The heat generated by the heating component 3 is transmitted to the inner wall of the shield 11 through the housing. Arranging the heating component 3 in the sandwich layer can reduce the probability of the heating component 3 being scratched or otherwise damaged, thereby reducing the risk of electric leakage of the heating component 3 and improving the safety of using the breast pump.

[0045] Optionally, as Figure 2 shown, the main body 2 includes a connected cylindrical part 21 and a boss part 22, and the heating component 3 is arranged on the boss part 22. It can be understood that by providing the boss part 22, it is convenient for the shield 11 to be placed on the heating component and for the shield 11 to be heated.

[0046] Optionally, the boss part 22 is a frustum of a cone, and the heating surface of the heating component 3 is in a horn shape, which is adapted to the shape of the outer peripheral surface of the boss part 22, and can improve the installation convenience and stability of the heating component 3.

[0047] Further optionally, as Figure 1 shown, the breast pump further includes a negative pressure pipeline 4. One end of the negative pressure pipeline 4 is connected and communicated with the main body 1, and the other end of the negative pressure pipeline 4 is connected and communicated with the cylindrical part 21. It can be understood that: the main body 2 is connected to the main body 1 through the negative pressure pipeline 4. During use, the user can place the main body 2 in an idle position and hold the main body 1 to perform the milk suction operation, which is labor-saving. Moreover, the connection position of the negative pressure pipeline 4 and the main body 2 is located at the cylindrical part 21, and the heating component 3 is arranged on the boss part 22, so that the negative pressure pipeline 4 and the heating component 3 do not interfere with each other, and the heating component 3 does not need to be provided with an avoidance structure, making the overall structure of the breast pump relatively simple.

[0048] Optionally, as Figure 4As shown in the figure, for the convenience of controlling whether the heating component 3 operates, the main body 2 further includes a battery 23 and a control switch 24 disposed in the housing. The battery 23 is used to supply power to the heating component 3. Of course, it can be understood that the battery 23 also supplies power to the vacuum generator. The control switch 24 is electrically connected to the battery 23, and the heating component 3 is electrically connected to the control switch 24, so that the control switch 24 can control the on-off of the circuit between the battery 23 and the heating component 3, thereby realizing the control of whether the heating component 3 operates. It can be understood that: the battery 23 disposed in the housing provides electrical energy to the heating component 3, and at the same time, a control switch 24 is disposed between the two to realize the on-off of the circuit therebetween, thereby controlling whether the battery 23 supplies electrical energy to the heating component 3, and further facilitating the control of whether the heating component 3 operates.

[0049] In some alternative embodiments, the battery 23 is disposed inside the housing, and the control switch 24 can be disposed on the housing and has a part exposed outside the housing. The user can press or touch the control switch 24 to realize the conduction or disconnection of the circuit. The control switch 24 can be a structure in the prior art, and details are not described herein in this embodiment.

[0050] To improve the comfort of the user, the breast pump further includes a temperature sensor (not shown in the figure). The temperature sensor is disposed on the shield 11 and is used to detect the temperature of the inner wall of the shield 11. The control switch 24 is configured to disconnect the electrical connection between the battery 23 and the heating component 3 when the temperature detected by the temperature sensor is greater than a preset temperature. It can be understood that: by disposing a temperature sensor inside the shield 11 for detecting the temperature of the inner wall of the shield 11, when the temperature detected by the temperature sensor is greater than the preset temperature, it means that the heating of the shield 11 has reached the requirement, then the electrical connection between the battery 23 and the heating component 3 is disconnected, and the heating of the heating component 3 is stopped, avoiding the overheating of the shield 11, which can further improve the comfort of the user and has high reliability. For example, the preset temperature can be 38 °C, 39 °C, etc., and the user can set it according to actual needs.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here.
