The indicators can be printed, such as "L" or "left" for the left side and "R" or "right" for the right side. They can also be illuminated, displayed, or voice-activated. Furthermore, an indicator light or display can be added to the breast pump 100 to indicate the current operating status. This allows the user to clearly identify which left breast the breast pump 100 is currently recording, allowing them to make appropriate adjustments or operations.

[0057] In some embodiments, the switching member 40 further includes an anti-slip portion 42 , which is located on the side of the first main body portion 41 ; the anti-slip portion 42 is inserted into the shell 10 and abuts against the top of the shell 10 to axially limit the switching member 40 .

[0058] The anti-slip portion 42 abuts against the top of the housing 10, thereby preventing the first main body 41 from being separated from the housing 10 through the opening 11. Furthermore, when the switching member 40 enters the housing 10, the anti-slip portion 42 receives abutting force from the edge of the opening 11, causing the anti-slip portion 42 to retract toward the first main body 41, thereby allowing the anti-slip portion 42 to follow the first main body 41 into the housing 10.

[0059] In some embodiments, the anti-slip portion 42 includes at least two anti-slip protrusions 421 , and the anti-slip protrusions 421 are symmetrically arranged on the circumference of the first main body portion 41 .

[0060] When the anti-slip portion 42 has two anti-slip protrusions 421, the two anti-slip protrusions 421 are respectively arranged on both sides of the first main body 41 and the two anti-slip protrusions 421 are symmetrically arranged. When the first main body 41 slides left and right or up and down, there is always one anti-slip protrusion 421 that abuts against the housing 10, so that the first main body 41 can always be located in the housing 10, and the anti-slip portion 42 will not be out of contact with the housing 10 due to the movement of the first main body 41. Through this arrangement, the first main body 41 is further secured in the housing 10, and the first main body 41 is prevented from being separated from the housing 10 when the first main body 41 slides.

[0061] In some embodiments, the anti-slip protrusion 421 includes an abutment portion 4211 and a guide portion 4212, the guide portion 4212 is connected to the first main body portion 41, and the abutment portion 4211 is arranged on one end of the guide portion 4212 away from the first main body portion 41; and the guide portion 4212 has a smooth curved surface.

[0062] The abutting portion 4211 of the anti-slip protrusion 421 is disposed toward the housing 10 , and the abutting portion 4211 abuts against the bottom shell, so that the anti-slip protrusion 421 abuts against the housing 10 to prevent the first main body 41 from being separated from the housing 10 .

[0063] It should be noted that the guide portion 4212 has a smooth curved surface that is recessed in a direction close to the first main portion 41. When the first main portion 41 enters the housing 10 through the opening 11, the smooth curved surface of the guide portion 4212 contacts the edge of the opening 11, and the smooth curved surface enables the first main portion 41 to pass through the opening 11 and enter the housing 10.

[0064] The guide portion 4212 has a certain degree of flexibility, so that the guide portion 4212 can move toward the first main body portion 41 while being in contact with the opening 11 , so that the first main body portion 41 enters the housing 10 through the opening 11 .

[0065] Specifically, the guide portion 4212 may be made of plastic or hard rubber.

[0066] In some embodiments, the first main body 41 is provided with an abutting groove 411 , the switch 30 includes a protrusion 31 , the abutting groove 411 and the protrusion 31 are adapted to each other; the protrusion 31 is accommodated in the abutting groove 411 , and the inner wall of the abutting groove 411 abuts against the protrusion 31 .

[0067] The first body portion 41 defines an abutment groove 411, which is located on one end of the first body portion 41 near the switch 30. Furthermore, the switch 30 is provided with a bump 31, which fits in the abutment groove 411 so that the bump 31 can be snapped into the abutment groove 411. This arrangement allows the first body portion 41 to connect with the switch 30, and when the switch 30 slides, the first body portion 41 can drive the switch 30 to slide, driven by the bump 31 on the switch 30.

[0068] In some embodiments, the housing 10 includes an upper cover 12 . The upper cover 12 covers the circuit board 20 . The upper cover 12 defines a mounting opening 121 . The switch 30 is located in the mounting opening 121 .

[0069] The mounting opening 121 is formed on the upper cover 12, which is mounted on the circuit board 20. The switch 30 is mounted on the circuit board 20 through the mounting opening 121. When the upper cover 12 is separated from the housing 10, the circuit board 20 can be removed from the housing 10. This arrangement facilitates the removal of the circuit board 20.

[0070] In some embodiments, a fixing groove 122 is further provided on the peripheral side of the upper cover 12 . The fixing groove 122 is disposed toward the circuit board 20 .
