[0003] In practical applications, users sometimes need to use a single-sided breast pump, and sometimes use a double-sided breast pump. The operation of the single and double side conversion device is complicated. In the process of converting a double side breast pump into a single side breast pump, the air flow rate of the double side vacuum negative pressure pump in the double side breast pump is larger than that of the single side vacuum negative pressure pump (unit L / min), the output negative pressure value is also smaller and the negative pressure intensity is greater. If you switch directly from a double-sided breast pump to a single-sided breast pump, the excessive negative pressure will be concentrated in the single-sided three-way collector, which will damage the breast pump. Pregnant women who are using this single-sided electric breast pump may cause problems such as breast pain and cracked breasts

Embodiment 1
[0056] Such as Figure 1 to Figure 9 As shown, the present invention provides a joint for single and double state conversion of breast pumps, including a joint body 1 and a sealing assembly 2;
[0057] The joint body 1 is a three-way pipe body, respectively a first channel 11, a second channel 12 for connecting with the breast pump collector, and a third channel 13 for connecting with the breast pump main body 4, The first passage 11, the second passage 12 and the third passage 13 communicate with each other;
[0058] The sealing assembly 2 is connected to the joint body 1 through a connection assembly 3, and the sealing assembly 2 is provided with a vent groove;
[0059] When in the state of unilateral breastfeeding, the sealing assembly 2 is embedded in the first channel 11 or the second channel 12 for deflation, and the side that is not connected to the sealing assembly 2 is connected to the breast pump collector connected, the third channel 12 is connected to the breast ...
Embodiment 2
[0080] Such as Figure 10 to Figure 14 As shown, the present invention also provides an electric breast pump, including the joint for single and double state conversion of the breast pump in any of the above embodiments, and also includes a breast pump host 4, a first collector 5 and a second 2 Collector 6;
[0081] The main body of the breast pump 4 is in communication with the third channel 13;
[0082] When in the state of unilateral breastfeeding, the first collector 5 communicates with the first channel 11, and the second sealing plug 22 is embedded in the second channel 12 for deflation, or,
[0083] The second collector 6 communicates with the second channel 12, and the first sealing plug 21 is embedded in the first channel 11 for air leakage;
[0084] When in the state of breastfeeding on both sides, the first collector 5 communicates with the first channel 11 , and the second collector 6 communicates with the second channel 12 .
[0085] The beneficial effect of th...

Abstract
The invention provides a connector for changing the single-side state and double-side state of a breast pump and an electric breast pump and relates to the technical field of utensils for mothers andinfants. The connector comprises a connector body and a sealing component and is characterized in that the connector body is a three-way tube, the three-way tube comprises a first channel, a second channel and a third channel which are communicated with one another, the sealing component is connected with the connector body through a connecting component and provided with air discharge grooves; ina single-side breast pumping state, the sealing component is embedded into the first channel or the second channel to discharge air, one side which is not connected with the sealing component is connected with a breast pump collector, and the third channel is connected with the breast pump; in a double-side breast pumping state, the first channel and the second channel are connected with the breast pump collector, the third channel is connected with the breast pump, and air discharge is not needed. The connector has the advantages that by the air discharge grooves, the negative pressure pumpof a double-side breast pump can be directly applied to a single-side breast pump, the negative pressure value of the negative pressure pump is kept unchanged when double-side breast pumping is switched into single-side breast pumping, and breast pain even chap can be avoided.
Description
technical field [0001] The invention relates to the technical field of maternity and infant appliances, in particular to a joint used for single and double state conversion of a breast pump and an electric breast pump. Background technique [0002] An electric breast pump is an instrument for postpartum use by pregnant women, and refers to a tool for expressing (sucking) the breast milk accumulated in the mammary gland. Change the internal air pressure through the internal vacuum negative pressure pump, that is, cycle "suction" - "release" to imitate the action of a baby sucking breast milk. With regard to existing electric breast pumps, there are two structural modes of unilateral breast pumps and bilateral breast pumps. Unilateral breast pump: a vacuum negative pressure pump connected to a three-way collector; double-sided breast pump: a vacuum negative pressure pump connected to two three-way collectors. [0003] In practical applications, users sometimes need to use a ...
