Description

Technical Field

[0001] The utility model relates to the technical field of breast pumps, in particular to a bra-type breast pump. Background Art

[0002] A breast pump is a tool used to express breast milk accumulated in the mammary glands and is an essential tool for breastfeeding mothers.

[0003] A wearable breast pump is a type of breast pump that works by being worn inside the mother's bra. The purpose of wearing it inside the bra is to free the mother's hands during the breastfeeding process, so that the mother can move around and do other things during the breastfeeding process.

[0004] In the prior art, for example, a breast pump with a matching breast milk storage device disclosed in Chinese Patent Application No. 200880129925.9 is a wearable breast pump, which explains the specific structure and working principle of the breast pump. However, the breast pump needs to be connected to a breast pump host for providing suction through a pipeline, which requires the mother to hold the breast pump host or wear specific clothes to fix the breast pump host during the breast pumping process, thereby making the wearing process cumbersome. In addition, during the use of the breast pump, the mother needs to avoid squeezing the pipeline between the breast pump host and the breast pump shield in the bra, which is easy to interfere with the mother's normal activities. Therefore, the wearable breast pump of the prior art is not convenient to use.

[0005] The breast pump controlled by a mobile phone terminal disclosed in Chinese patent application No. 201510100947.4 provides a method for remotely controlling the operation of a breast pump main unit, so that the mother can conveniently control the suction force. However, it does not allow a long pipe to be connected between the breast pump main unit and the breast pump cover, so that the mother does not need to carry the breast pump main unit when moving, because the long pipe will lead to a decrease in the suction effect; and the pipe between the breast pump main unit and the breast shield cover will still affect the mother's movements.

[0027] The technical solutions in the embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0028] Embodiment 1: In the prior art, a wearable breast pump is a breast pump shield placed inside a bra, and the vent on the breast pump shield is connected to an external breast pump host through a pipe. Therefore, during the process of breast pumping, the mother can avoid holding the two breast pump shields with both hands, and instead use the bra to fix the breast pump shields on the mother's chest. However, the connecting pipe between the breast pump shield and the breast pump host will still affect the mother's activities, because the mother's hands may touch the pipe, and the pipe may collide and squeeze with other external structures due to the mother's activities, resulting in the breast pump host being unable to provide suction to the breast pump shield normally (the breast pump shield here is the prior art, such as a wearable breast pump cup assembly disclosed in Chinese patent application No. 202321675515.2, which discloses a specific structure and working principle of a breast pump shield). The bra-type breast pump provided in Embodiment 1 of the utility model is Figures 1 to 10 As shown, the bra comprises a bra shell 1, two breast pump shields 2 and a breast pump host 3; the bra shell 1 comprises a first shell 11, a second shell 12, a central shell 13 and an elastic band 14; the first shell 11 and the second shell 12 are respectively fixed to opposite sides of the central shell 13; the two ends of the elastic band 14 are respectively fixed to the first shell 11 and the second shell 12; the first shell 11, the central shell 13, the second shell 12 and the elastic band 14 are surrounded to form a ring; the first shell 11 is provided with a first accommodating groove 111; the second shell 12 is provided with a second accommodating groove 121; a breast pump shield 2 is detachably fixed in the first accommodating groove 111; a breast pump shield 2 is detachably fixed in the second accommodating groove 121 A breast pump shield 2; a breast pump main unit 3 is arranged in the central shell 13; the breast pump main unit 3 includes two vents; the two vents are respectively connected to a suction pipe 4 that passes through the central shell 13; the output port of one suction pipe 4 is connected to the first receiving groove 111, and the output port of the other suction pipe 4 is connected to the second receiving groove 121; the breast pump shield 2 includes a communication port 21; when the breast pump shield 2 is fixed in the first receiving groove 111, the communication port 21 of the breast pump shield 2 is tightly connected to the suction pipe 4 in the first receiving groove 111; when the breast pump shield 2 is fixed in the second receiving groove 121, the communication port 21 of the breast pump shield 2 is tightly connected to the suction pipe 4 in the second receiving groove 121.

[0029] When the bra-type breast pump provided by Example 1 of the utility model is in use, a breast pump shield 2 needs to be fixed in the first receiving groove 111 of the first shell 11 and in the second receiving groove 121 of the second shell 12 respectively. The ring formed by the first shell 11, the central shell 13, the second shell 12 and the elastic band 14 just surrounds the mother's chest. By controlling the tightness of the elastic band 14, the two breast pump shields 2 are close to the two breasts of the mother. At this time, the mother can move around without holding the two breast pump shields 2 with her hands. By controlling the operation of the breast pump host 3, the breast pump host 3 provides suction, and the suction is provided to the two breast pump shields 2 respectively through the suction pipe 4. The breast pump shields 2 provide suction to the mother's breasts to achieve milk suction, and the sucked milk enters the breast pump shields 2 for storage. Compared with the prior art, in which the pipeline connecting the breast pump main unit 3 and the breast pump shield 2 will affect the mother's movements, the device provided in this embodiment has the suction pipe 4 placed inside the bra shell 1 and will not be directly exposed to the outside. Therefore, when the mother is moving, the suction pipe 4 can be prevented from being squeezed by external conditions, which ultimately affects the suction force and the milk sucking process. The mother does not need to fix the breast pump main unit separately to move, and the mother's movements are more convenient.

[0030] The bra-type breast pump provided in Example 1 of the utility model solves the problem in the prior art that it is inconvenient for mothers to move while using the breast pump, and can facilitate mothers to move while using the breast pump.

[0031] As a preferred solution, in this embodiment, the first shell 11 is rotatably connected to the center shell 13; the second shell 12 is rotatably connected to the center shell 13; after the first shell 11 rotates relative to the center shell 13 and the second shell 12 rotates relative to the center shell 13, a state exists such that the opening of the first accommodating groove 111 coincides with the opening of the second accommodating groove 121. The first shell 11 and the second shell 12 can be rotated respectively compared with the central shell 13, so that after the mother takes out the breast pump shield 2 in the first receiving groove 111 and the second receiving groove 121, the openings in the first receiving groove 111 and the second receiving groove 121 can be closed, thereby reducing the dust falling into the first receiving groove 111 and the second receiving groove 121 when storing the bra shell (after the breast pump shield 2 is taken out, the milk inside it needs to be cleaned and dried after use, while the bra shell 1 and the breast pump host 3 and other structures inside it do not need to be cleaned after each use, and when the breast pump is not in use, the bra shell 1 and the breast pump shield 2 need to be stored separately).

[0032] In order to specifically realize the alignment of the openings of the first accommodating groove 111 and the second accommodating groove 121, as a preferred scheme, in this embodiment, a rotating shaft 131 is fixed on the central shell 13; the first shell 11 can be rotatably fixed on the rotating shaft 131; the rotation axis of the first shell 11 compared with the central shell 13 is the axis of the rotating shaft 131; the second shell 12 can be rotatably fixed on the rotating shaft 131; the rotation axis of the second shell 12 compared with the central shell 13 is the axis of the rotating shaft 131; during the rotation process of the opening of the first accommodating groove 111 around the axis of the rotating shaft 131, there is a state of overlap with the opening of the second accommodating groove 121. The first shell 11 and the second shell 12 can be rotatably fixed by a rotating shaft fixed on the central shell 13, so that the first shell 11 and the second shell 12 can rotate relative to the rotating shaft 131 of the central shell 13, thereby realizing the change of position of the first receiving groove 111 and the second receiving groove 121 on the first shell 11 and the second shell 12, and realizing the overlap of the openings of the first shell 11 and the second shell 12, and utilizing the structural parts of the first shell 11 and the second shell 12 except the first receiving groove 111 and the second receiving groove 121 to prevent dust from entering the first receiving groove 111 and the second receiving groove 121.

[0033] The breast pump host is a prior art. The comparative document mentioned in the background technology, Chinese patent application No. 201510100947.4, discloses a breast pump controlled by a mobile phone terminal. The remotely controlled breast pump host provided by the breast pump host can facilitate the mother to remotely operate the breast pump host. As a preferred solution, in this embodiment, the breast pump host 3 includes an air pump 31, a battery 32, two solenoid valves 33 and a control board 34; the air outlet of the air pump 31 is connected to the inlet of the solenoid valve 33 through a pipeline; the outlet of the solenoid valve 33 is connected to the suction pipe 4; the air pump 31 is electrically connected to the control board 34; the battery 32 is electrically connected to the control board 34; the solenoid valve 33 is electrically connected to the control board 34; and the control board 34 is electrically connected to a wireless signal transmission module 341. In this embodiment, a breast pump host that can be remotely controlled is used. All components inside the breast pump host are powered by a battery 32. An external device (such as a mobile phone) gives instructions to a wireless signal transmission module 341, thereby controlling the air pump 31 and the solenoid valve 33 through the control panel 34, and transmitting signals to the external device through the wireless signal transmission module 341, thereby monitoring the power of the battery 32 and the working status of the air pump 31 and the solenoid valve 33, so that the mother can control the breast pump host conveniently; the suction force is provided and the size of the suction force is controlled by controlling the operation of the air pump 31, and the suction force is turned on and off by controlling the operation of the solenoid valve 33. (Placing the breast pump host in a shell and realizing external powering or replacing the power supply of the breast pump host in the shell is a prior art and will not be elaborated here).

[0034] The breast pump shield 2 is a prior art. The breast pump shield 2 has a funnel inner wall close to the breast and a cavity for storing milk. As a preferred solution, in this embodiment, the breast pump shield 2 includes a funnel-shaped base 22, a tee 23 and a hood-shaped shell 24; the shell 24 is detachably fixed to the base 22; when the shell 24 is fixed to the base 22, the small funnel opening of the base 22 faces the inner cavity of the shell 24; the large funnel opening of the base 22 is tightly closed with the hood-shaped opening of the shell 24; the tee 23 is fixed to the base 22, and the hood-shaped opening of the shell 24 is closed. It is arranged in the space formed by the shell 24 and the base 22; the tee 23 includes a milk inlet 231, a negative pressure port 232 and a milk outlet 233; the funnel-shaped opening of the base 22 is airtightly connected to the milk inlet 231 of the tee 23; a connecting port 21 is arranged on the shell 24; the connecting port 21 is airtightly connected to the negative pressure port 231; the connecting port 21 and the negative pressure port 231 are isolated by a flexible membrane 25; the milk outlet 233 is connected to the inlet of the duckbill valve 26; the outlet of the duckbill valve 26 is in the inner cavity of the shell 24. When the breast pump host 3 is working and provides suction, the suction is provided to the breast pump shield 2 along the suction pipe 4, and the suction pipe 4 provides suction to the connecting port 21, so that the air pressure in the space between the flexible membrane 25 and the shell 24 becomes smaller, and the flexible membrane 25 is deformed, so that the air pressure in the space on the other side of the flexible membrane 25, which is composed of the mother's breast, the inner wall of the tee 23 and the flexible membrane 25, becomes smaller. The reduced air pressure causes the mother's breast to be subjected to suction, and the mother's nipple secretes milk, which enters the tee 23 from the inlet 231. Since the negative pressure port 232 is blocked by the flexible 25, the milk will gather at the milk outlet 233. When the amount of milk reaches a certain level, the gravity of the milk causes the duckbill valve 26 at the milk outlet 233 to be stuck, and the milk enters the space composed of the hood-shaped inner wall of the shell 24 and the funnel outer wall of the base 22 for temporary storage.

[0035] In order to facilitate the mother to take out the breast pump shield 2 from the first shell 11 and the second shell 12, as a preferred solution, in this embodiment, a support bottom plate 241 is fixed on the shell 24; the support bottom plate 241 has a support edge in the same horizontal plane; the breast pump shield 2 can be stably placed against the upper surface of the horizontal plane through the support edge; a milk pouring port 221 is provided on the base 22; the milk pouring port 221 is arranged on the top of the base 22 after the breast pump shield 2 can be stably placed through the support edge. The support bottom plate 241 has a support edge in the same plane, so that the breast pump shield 2 can be stably placed on the desktop through the support edge against the bottom surface of the horizontal plane, thereby ensuring that the milk pouring port 221 is vertically upward, thereby avoiding the milk pouring port 221 facing downward, resulting in milk leakage at the milk pouring port 221.
