Description

Breast pump with cleaning device

Technical Field

The utility model relates to the field of breast pumps, in particular to a breast pump with a cleaning device.

Background

In recent years, breast pumps which help users to discharge breast milk from breasts are becoming popular, and among them, the breast pumps can be simply classified into manual breast pumps and electric breast pumps according to the power source of the breast pump.

The prior art electric breast pump is composed of a container and a cup which are mounted together, a piston pump and a battery which are integrated and connected together, and a connection pipe for connecting the piston pump and the container or the connection pipe for connecting the piston pump and the cup. When the breast pump is used for sucking milk, the breast is wrapped by the cup, the battery provides power to enable the piston pump to work, the piston pump enables negative pressure to be generated in the cup through the connecting pipe, so that the breast milk is discharged out of the body from the breast, and the breast milk is guided into the container, and therefore the milk sucking operation is carried out. The connecting pipe of breast pump is thinner and longer hose or hard tube, under the general condition, the internal diameter size of connecting pipe is about 2mm or 3mm, the length of connecting pipe is about 500mm, when the breast pump is deposited, pollutants such as dust can get into the inside of connecting pipe and depend on the inner wall of connecting pipe, in addition, when the breast pump is used, the fat that carries in the breast milk, material such as protein can the adhesion form the milk stain on the inner wall of connecting pipe, these milk stains if stop for a long time in the connecting pipe, can make the inner space of connecting pipe form the good environment of breeding the bacterium, and in case this kind of condition appears, must lead to the fact the threat for breast milk safety. Therefore, it can be understood that the container, cup, piston pump, connecting tube, etc. of the breast pump need to be cleaned and sterilized before and after use to ensure the safety of breast milk. However, the construction of prior art electric breast pumps has resulted in the inability to clean and sterilize the connecting tubes and piston pumps of the breast pump.

First, the mode of each part of first washing breast pump is washed using the clear water, because the internal diameter of connecting pipe is less and the length of connecting pipe is longer, when using clear water to wash the connecting pipe, rivers hardly enter into the inside of connecting pipe, even if rivers enter into the inside of connecting pipe, because the water yield is less and lead to water velocity slow, so that lead to the rivers that just lead to entering into the inside of connecting pipe can't wash away the dust of adsorbing on the inner wall of connecting pipe, the bacterium, pollutants such as milk stain. In addition, water entering the inside of the connection pipe may remain inside the connection pipe, which may also contaminate the inside of the connection pipe. Similarly, the inner space of the piston pump is small and invisible, so that pollutants such as dust, bacteria and milk stain attached to the inner wall of the piston pump can not be washed clean by the clean water.

Secondly, the second mode of washing each part of breast pump is to use high temperature cooking, when cooking the connecting pipe of breast pump, the water that is heated equally can't enter into the inner wall of connecting pipe effectively, although the vapor that the water that is heated formed can smoothly pass through the inside of connecting pipe unimpededly to rely on pasteurization, nevertheless the milk stain of steam still can't clear up effectively and depend on the inner wall of connecting pipe, the milk stain of long-term dependence on the inner wall of connecting pipe can lead to the connecting pipe to appear yellowing, bad phenomena such as blacking, so that lead to the connecting pipe can't be used by continuation. Since the piston pump and the battery are integrated together, the interior of the piston pump cannot be cleaned and sterilized by means of autoclaving, which results in contaminants such as dust, bacteria, milk stain, etc. entering the interior of the piston pump and adhering to the inner wall of the piston pump being unable to be cleaned and sterilized, so that the safety of breast milk is seriously affected.

In addition, when the connection tube of the breast pump cannot be cleaned and sterilized, although the user can continue to use the breast pump by replacing the connection tube with a new one, this will increase the use cost of the breast pump on the one hand, and also cause environmental pollution and waste of resources on the other hand.

Normally, the relief valve 19 is in a closed state to form a negative pressure environment in the fluid passage 13 when the vacuum generator 12 is operated, for example, when the cleaning device 10 is used to clean the connection pipe 100, the relief valve 19 is in a closed state to form a negative pressure environment in the fluid passage 13 when the vacuum generator 12 is operated.

It is to be noted that the pressure relief valve 19 may be a manual valve or an electrically operated valve, for example, when the pressure relief valve 19 is implemented as an electrically operated valve, the pressure relief valve 19 may be electrically connected to the power supply unit 14. In other words, the type of the pressure relief valve 19 is not limited in the cleaning device 10 of the present invention.

Referring to fig. 3A and 3B, the cleaning device 10 may clean the connection pipe 100 one at a time, wherein an end of the connection pipe 100 may be installed at the inflow end 111 or the outflow end 112 of the cleaning body 11 of the cleaning device 10. Referring to fig. 4A and 4B, the cleaning device 10 can also clean two connection pipes 100 at a time, wherein the end of each connection end 100 is respectively installed at the inflow end 111 and the outflow end 112 of the cleaning body 11 of the cleaning device 10. In the following description, taking the cleaning device 10 to clean the connecting pipe 100 one at a time, and the end of the connecting pipe 100 is mounted on the inlet end 111 of the cleaning body 11 of the cleaning device 10 as an example, the process of the cleaning device 10 used for cleaning the connecting pipe 100 will be described to further illustrate the features and advantages of the cleaning device 10 of the present invention.

In addition, for convenience of explanation and understanding, the ends of the connection pipe 100 are defined as a mounting end 101 and a free end 102, respectively, wherein the end of the connection pipe 100, which is used to be mounted to the inflow end 111 of the cleaning body 11, is defined as the mounting end 101, and the other end of the connection pipe 100 is defined as the free end 102. It will be understood by those skilled in the art that the end portions of the connecting tube 100 are respectively defined as the mounting end 101 and the free end 102 for convenience of illustration and explanation only, and the cleaning device 10 and the process of cleaning the connecting tube 100 using the cleaning device 10 are not to be considered as limitations to the content and scope of the cleaning device 10 of the present invention.

Specifically, the attachment end 101 of the connection pipe 100 is attached to the inlet end 111 of the cleaning body 11 of the cleaning apparatus 10 such that the inner space of the connection pipe 100 communicates with the fluid passage 13 through the inlet 1110 at the inlet end 111. The free end 102 of the connecting tube 100 is placed below a liquid level 201, for example, a liquid 200 is contained in a container 300, wherein the liquid level 201 forms the liquid level 201, and the free end 102 of the connecting tube 100 is inserted and maintained below the liquid level 201.

It is worth mentioning that in this example of the cleaning device 10 of the present invention, the fluid may be embodied as the liquid 200, of course, in other examples of the cleaning device 10, the fluid may also be embodied as a gas or a mixture of a gas and a liquid, the cleaning device 10 of the present invention is not limited in this respect.

The power supply unit 14 supplies power to the vacuum generator 12 to operate the vacuum generator 12, and at this time, the vacuum generator 12 forms a negative pressure environment in the fluid passage 13, so that the liquid 200 contained in the container 300 enters the inner space of the connection pipe 100 from the free end 102 of the connection pipe 100, is discharged from the connection end 102 of the connection pipe 100, and enters the fluid passage 13 from the inflow end 111 of the cleaning body 11 and is discharged from the fluid passage 13 from the outflow end 112 of the cleaning body 11, thereby cleaning the inner space of the connection pipe 100. It will be appreciated that the fluid path 13 may also be cleaned by the liquid 200.

It is worth mentioning that the vacuum generator 12 enables the negative pressure generated in the fluid passage 13 to make the liquid 200 flow rapidly in the inner space of the connection pipe 100, thereby cleaning contaminants, such as dust, bacteria and milk stain, attached to the inner wall of the connection pipe 100 by washing the inner wall of the connection pipe 100.

Preferably, the electric power supply unit 14 supplies electric power to the pressure release 18 to place the pressure release 18 in an operating state, and at this time, the pressure release 18 causes the fluid passage 13 to alternately generate the first negative pressure and the second negative pressure. When the pressure releaser 18 causes the first negative pressure to be generated in the fluid passage 13, the liquid 200 can enter the internal space of the connection pipe 100 from the free end 102 of the connection pipe 100 and can be discharged from the connection end 101 of the connection pipe 100 into the internal space of the connection pipe 100 at a higher speed, and when the pressure releaser 18 causes the second negative pressure to be generated in the fluid passage 13, the liquid 200 can enter the internal space of the connection pipe 100 from the free end 102 of the connection pipe 100 and can be discharged from the connection end 101 of the connection pipe 100 into the internal space of the connection pipe 100 at a lower speed.

That is, the pressure releaser 18 can make the liquid 200 enter the inner space of the connection pipe 100 in a fast and slow alternating manner to wash the inner wall of the connection pipe 100 by making the first negative pressure and the second negative pressure alternately generated in the fluid passage 13, thereby effectively cleaning the contaminants such as dust, bacteria and milk stain attached to the inner wall of the connection pipe 100, which is not expected in the prior art of cleaning the connection pipe 100, and is particularly effective for improving the cleanness and sanitation of the inner space of the connection pipe 100.

In addition, when the cleaning device 10 is used to clean the connection pipe 100, the liquid 200 may also enter the inside of the vacuum generator 12 and the pressure releaser 18 to clean the vacuum generator and the pressure releaser 18, thereby further ensuring the reliability of the connection pipe 100 after being cleaned.

It is understood that, during the process of cleaning the connection tube 100 by using the cleaning device 10, whether the pressure releaser 18 generates the first negative pressure or the second negative pressure in the fluid passage 13, the fluid passage 13 is in a negative pressure environment, so that the liquid 200 can continuously enter the inner space of the connection tube 100 from the free end 102 of the connection tube 100. The pressure release 18 enables the first negative pressure and the second negative pressure generated by the fluid passage 13 to generate alternate fast and slow changes of the liquid 200 entering the inner space of the connecting pipe 100 from the free end 102 of the connecting pipe 100, so as to provide better flushing effect.

After the connection pipe 100 is cleaned by the cleaning device 10, the supply of electric power to the vacuum generator 12 and the pressure releaser 18 may be stopped, and the external environment and the fluid passage 13 may be communicated through the relief valve 19 to eliminate the negative pressure environment generated in the fluid passage 13.

Referring to fig. 5, in accordance with another aspect of the present invention, the present invention further provides a method 500 of cleaning the connection pipe 100 by the cleaning device 10, wherein the cleaning method 500 includes the steps of:

Preferably, the milk container 30 and the support frame 40 may be detachably connected by a screw connection, however, the milk container 30 and the support frame 40 may be detachably connected by a connection such as a snap connection.

The washing device 10 is detachably mounted to the first mounting position 401 of the supporting frame 40, so that when the washing device 10 is mounted to the first mounting position 401 of the supporting frame 40, the inlet 1110 of the washing body 11 of the washing device 10 is communicated with the first channel 41, thereby communicating the milk containing space 31 of the milk container 30 and the fluid passage 13 of the washing device 10 via the first channel 41. It is understood that when the cleaning device 10 is mounted at the first mounting position 401 of the supporting frame 40, the inlet end 111 of the cleaning body 11 of the cleaning device 10 can be inserted into the first channel 41 of the supporting frame 40, so that the inlet 1110 of the cleaning body 11 is communicated with the first channel 41 of the supporting frame 40.

The breast accommodating device 20 is detachably connected to the second mounting position 402 of the supporting frame 40, so that when the breast accommodating device 20 is mounted to the second mounting position 402 of the supporting frame 40, the accommodating space 21 of the breast accommodating device 20 is connected to the second passage 42 of the supporting frame 40, and the second passage 42 of the supporting frame 40 is connected to the accommodating space 21 of the breast accommodating device 20 and the milk containing space 31 of the milk container 30.
