Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of breast milk products, in particular to a breast pump. BACKGROUND

[0002] The breast pump is a device for helping users to discharge breast milk from the breast, and the breast is a very sensitive part of the human body. The breast pump generates negative pressure in its interior to suck out the milk and store it. Scientific research data and actual use experience show that hot compress during breast pumping has obvious effects on increasing the amount of milk, relieving breast congestion, and reducing the pain during breastfeeding. When the ambient temperature is low, if the breast directly contacts the breast pump, a relatively strong cold feeling is easily generated, causing discomfort in the body feeling and also reducing the amount of milk. Therefore, before using the breast pump, the user will try to raise the temperature of the cover cup of the breast pump. The current method is to soak or steam the cover cup in hot water to raise the temperature of the cover cup. However, this method is very troublesome, and the temperature of the cover cup is difficult to maintain. When the breast pump is used for more than a certain time, the temperature of the cover cup will continue to decrease rapidly, especially in the cold winter season, the temperature of the cover cup decreases even faster.

The appearance of the phrase in various places in the specification is not necessarily all referring to the same embodiment, nor is it necessarily referring to a particular embodiment that is "preferred" over other embodiments. Those skilled in the art will appreciate that embodiments described herein can be combined with other embodiments.

[0031] The embodiments of the application provide a breast pump, please refer to Figure 1 and Figure 2 The breast pump includes a milk bottle 10, a liquid suction member 20 and a host 30; the milk bottle 10 is provided with a milk storage cavity 101; the liquid suction member 20 includes a liquid guide pipe 210 and a horn cover 220 connected to the liquid guide pipe 210, the outer diameter of the horn cover 220 gradually expands in the direction away from the liquid guide pipe 210, the horn cover 220 is in communication with the milk storage cavity 101 through the liquid guide pipe 210, and the horn cover 220 is provided with a heating member 230; the host 30 is connected between the milk bottle 10 and the liquid guide pipe 210, the host 30 is used to generate negative pressure in the milk storage cavity 101 to suck milk, and the host 30 is electrically connected with the heating member 230.

[0032] Currently, a hot towel, a hot compress bag or a massage instrument that can generate heat is used for hot compress around the breast when a lactating mother pumps milk. The current solution has disadvantages in terms of effect and convenience: first, when using a breast pump, the breast is already surrounded by the cover cup of the breast pump, and the hot towel, hot compress bag or heating instrument can only contact a very limited range, and can only be hot compressed at the outer edge of the breast or a fixed position, greatly weakening the hot compress effect. Second, the hot compress towel and hot compress bag have a holding time of less than 2 minutes, and the temperature drops quickly; and placing another object (hot towel, massage instrument) on the breast while using the breast pump makes the already heavy task of pumping more troublesome. The breast pump of the present application, when in use, the horn cover 220 is in close contact with the breast to suck milk, and the heating element 230 can heat the part of the horn cover 220 in contact with the breast through the power supply of the host, thereby improving the comfort of the user during the pumping process, so that the horn cover 220 is constantly heated, and the breast can avoid the uncomfortable feeling caused by the cold stimulation of the breast when in contact with the horn cover 220, thereby avoiding the problem of reduced milk output due to breast discomfort. At the same time, the milk sucked by the horn cover 220 can flow to the milk storage cavity 101 through the liquid guide pipe 210, and the independently arranged milk bottle 10 can be easily detached from the breast pump to facilitate the storage and transfer of milk.

[0033] Specifically, the material of the milk bottle 10 can be glass, plastic or silicone, and the material of the milk bottle 10 needs to meet the corresponding food safety standards. In some embodiments, the milk bottle 10 needs to be boiled in high-temperature water for sterilization when cleaning, so the material of the milk bottle 10 can also be a high-temperature resistant material.

[0034] Optionally, the liquid suction element 20 includes a first liquid suction element 240 and a second liquid suction element 250 located on the side of the first liquid suction element 240 away from the host 30, and the heating element 230 is located between the first liquid suction element 240 and the second liquid suction element 250. The first liquid suction element 240 and the second liquid suction element 250 are fixedly connected, and the material of the first liquid suction element 240 and the material of the second liquid suction element 250 are different. The first liquid suction element 240 is in contact with the host 30, and the second liquid suction element 250 is in contact with the user. The first liquid suction element 240 can include a three-way structure to use the negative pressure generated by the host 30 to suck the milk of the breast and guide the milk into the milk storage cavity 101.

[0035] Furthermore, the first absorbent component 240 can be made of hard plastic to provide some support for the second absorbent component 250, while also facilitating the positioning and fixation of the entire absorbent component 20 to the main unit 30. The second absorbent component 250 can be made of either soft or hard plastic as needed. Specifically, the second absorbent component 250 can be made of soft plastic to ensure that it can cover the breast well without causing harm. Both the first absorbent component 240 and the second absorbent component 250 need to meet the corresponding food safety and high-temperature resistance standards.

[0036] In some embodiments, the first absorbent member 240 may be solid silicone, and the second absorbent member 250 may be liquid silicone. In some embodiments, the first absorbent member 240 and the second absorbent member 250 may both be made of soft silicone or both of hard silicone.

Further, the first absorbent member 240 and the second absorbent member 250 may be fixed together by means of bonding, snap-fitting, screw connection, or other methods.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, the main unit 30 includes a housing 310, which is connected between the liquid suction member 20 and the baby bottle 10. The housing 310 has a mounting groove 3101, in which the liquid suction member 20 is inserted.

[0038] Optionally, the heating element 230 may include a carrier plate 231 and an electric heating element 232, with the electric heating element 232 fixed to the carrier plate 231.

[0039] In some embodiments, the heating element 230 may be located between the first liquid absorber 240 and the second liquid absorber 250. For example, the heating element 230 may be attached to the surface of the second liquid absorber 250 near the first liquid absorber 240, and when the first liquid absorber 240 and the second liquid absorber 250 are fixedly connected, the heating element 230 may be pressed and fixed between the first liquid absorber 240 and the second liquid absorber 250.

[0040] In some embodiments, the heating element 230 can be embedded in the second liquid absorbing element 250, and the heating element 230 can be fixedly connected with the second liquid absorbing element 250 by injection molding.

[0041] Specifically, the heating element 230 can have a ring shape, and can be arranged around the liquid guide pipe 210 and fixed to the horn cover 220. The electric heating element 232 can extend spirally around the contour of the horn cover 220.

[0042] Optionally, the horn cover 220 is provided with a temperature sensor 280, and the temperature sensor 280 can be arranged on the carrier sheet 231.

[0043] Further, the number of the first conductive elements 270 is three, and the first conductive elements 270 are used to electrically connect the temperature sensor 280 and the heating element 230. The temperature sensor 280 can be a semiconductor device (with positive and negative polarities) or a thermistor (without polarity). One electrode of the temperature sensor 280 and one electrode of the heating element 230 are electrically connected to the same first conductive element 270. Specifically, the three first conductive elements 270 can be distributed side by side. The left and right first conductive elements 270 are respectively connected to the positive and negative electrodes of the electric heating element 232, and the middle first conductive element 270 forms a loop with the negative electrode of the electric heating element 232 through the temperature sensor 280, and the temperature sensor 280 is used to monitor the temperature of the heating element 230 in real time. In other embodiments, the number of the first conductive elements 270 can be multiple, for example, the number of the first conductive elements 270 can be four, corresponding to the positive and negative electrodes of the temperature sensor 280 and the positive and negative electrodes of the electric heating element 232.

[0044] Further, the first conductive member 270 can be in a column shape, the first liquid absorbing member 240 can include a first horn cover 244, the second liquid absorbing member 250 can include a second horn cover 252, the heating member 230 can be located between the first horn cover 244 and the second horn cover 252, and the first conductive member 270 can protrude from the heating member 230 towards the first horn cover 244. The first horn cover 244 can be provided with a corresponding positioning hole 2403, the first conductive member 270 can be inserted into the positioning hole 2403, and the first conductive member 270 can be electrically connected to the second conductive member 320 of the host 30 through the positioning hole 2403. In some embodiments, the first conductive member 270 can also contact the second conductive member 320 through the positioning hole 2403 to form an electrical connection. The number of the positioning holes 2403 can correspond to the number of the first conductive members 270. The number of the second conductive members 320 can correspond to the number of the first conductive members 270, and the second conductive members 320 can be pogopins. Pogopin is a kind of precision connector used in electronic products such as mobile phones, and the Chinese name of pogopin is spring needle.

[0045] Further, the host 30 can include a battery 330 located in the shell 310. The battery 330 can be electrically connected to the second conductive member 320, and the first conductive member 270 can abut against the second conductive member 320, so that the battery 330 can supply power to the heating member 230. The heating member 230 can be completely sealed in the liquid absorbing member 20 by the first liquid absorbing member 240 and the second liquid absorbing member 250, and does not directly contact the human body and breast milk. The temperature sensor 280 can measure the temperature of the liquid absorbing member 20 multiple times per second and directly transmit the temperature information to a microprocessor (not shown in the figure) of the host 30. The microprocessor can intelligently adjust the heating member 230, adjust the heating power of the heating member 230, and keep the temperature of the horn cover 220 in an appropriate range, so that the user can suck milk at the most safe and comfortable temperature. For example, when the air temperature is relatively cold, the microprocessor can increase the heating power of the heating member 230 to increase the temperature of the horn cover 220. When the air temperature is hot, the microprocessor can reduce the heating power of the heating member 230 or stop the heating member 230 from working, so that the temperature of the horn cover 220 is appropriate. The user can also set a predetermined temperature according to his own use, and the microprocessor can keep the horn cover 220 at the predetermined temperature or in the predetermined temperature range through intelligent adjustment.

[0046] Optionally, please refer to Figures 6 to 8In some embodiments, the liquid suction member 20 comprises a first liquid suction member 240 and a liquid suction assembly 200 located on the side of the first liquid suction member 240 away from the main machine 30.
