Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products, and more specifically to a breast pump with noise reduction and stable suction. Background Technology

[0002] Electric breast pumps are increasingly used as a tool for expressing breast milk. They are popular due to their strong suction and ease of use, eliminating the need for manual operation. However, the vibration and noise generated during operation can be bothersome and disruptive to infants, especially at night.

[0003] The soundproofing structure outside the pump of a conventional electric breast pump cannot solve the pump noise and vibration. Moreover, because the pump noise and vibration are too loud, it is often necessary to manually limit the operation of the pump, making it difficult for the electric breast pump to pump milk stably. Utility Model Content

An elastic support assembly is provided between the pump chamber and the base. The elastic support assembly supports the pump chamber and makes the pump chamber and the base fit with a gap. The elastic support assembly itself is elastic and can filter most of the vibration and noise, reducing the vibration and noise transmitted to the base. That is, it greatly reduces the noise and vibration generated by the pump, which greatly facilitates the high-efficiency and high-performance operation of the pump, and enables the electric breast pump to suck milk stably.

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] See appendix Figures 1 to 12The described invention relates to a noise-reducing and suction-stabilizing breast pump, comprising a base 100 and at least one pump assembly 200 disposed within the base 100, and a pump chamber 300 for supporting the pump assembly 200. The pump chamber 300 is clearance-fitted with the base 100, and an elastic support assembly 400 is provided between the pump chamber 300 and the base 100. By providing the pump chamber 300 to support the pump assembly 200, most of the noise and vibration of the pump assembly 200 can be absorbed. Furthermore, the clearance fit between the pump chamber 300 and the base 100 makes it difficult for noise and vibration from the pump chamber 300 to be transmitted through the pump chamber 300. The vibration and noise of the pump are directly transmitted to the base 100, resulting in less overall vibration and noise in the breast pump. An elastic support component 400 is provided between the pump chamber 300 and the base 100. The elastic support component 400 supports the pump chamber 300 and ensures a clearance fit between the pump chamber 300 and the base 100. The elastic support component 400 itself is elastic and can filter out most of the vibration and noise, reducing the vibration and noise transmitted to the base 100. This greatly reduces the noise and vibration generated by the pump, greatly facilitating the high-efficiency and high-performance operation of the pump, and enabling the electric breast pump to pump milk stably.

[0035] See appendix Figures 2 to 5The elastic support assembly 400 further includes a plurality of elastic bodies 410 for supporting the pump chamber 300. The elastic support assembly 400 is fixed to a support column 420 inside the base 100. The elastic bodies 410 are disposed on the support column 420. The support column 420 greatly reduces the transmission volume of vibration and noise. The pump chamber 300 is only connected to the elastic body 410. Vibration and noise on the pump chamber 300 are absorbed and reduced by the elastic body 410, which can greatly reduce vibration and noise and make it difficult to transmit vibration and noise on the pump chamber 300 to the support column 420 and the base 100. The elastic body 410 includes an upper buffer ring 411 and a lower buffer ring 412. The elastic body 410 also includes a slot 413 disposed between the upper buffer ring 411 and the lower buffer ring 412. The side wall of the pump chamber 300 is provided with a plurality of lugs 320 that match the slots 413. The upper buffer ring 411 and the lower buffer ring 412 can wrap the lugs 320 more efficiently and absorb vibrations transmitted from the lugs 320 in more directions. The upper buffer ring 411 and the lower buffer ring 412 are both provided with hollow cavities 413 to further increase the effect of vibration reduction and noise reduction. The elastomer 410 is sleeved on the support column 420, with a gap between the elastomer 410 and the support column 420. Because the elastomer 410 is an elastic structure, it deforms during actual vibration damping. This means the pump chamber 300 can sway up and down and left and right slightly during the vibration damping process. The elastomer 410 can also move up and down along the axial direction of the support column 420. Thus, the movement of the pump chamber 300 itself absorbs most of the vibration and noise, further reducing the vibration and noise transmitted by the elastomer 410. A buffer layer is provided between the pump body assembly 200 and the pump chamber 300 to further reduce vibration and noise in the pump chamber 300. In actual testing, the average noise level measured at a radius of 1.5m was 31.1dB, far below the market average.

[0036] See appendix Figure 6The pump assembly 200 includes a pump body 210 and a connecting pipe 220 communicating with the pump body 210. The pump chamber 300 has an opening 310 through which the connecting pipe 220 passes. A gap is provided between the edge of the opening 310 and the outer wall of the connecting pipe 220 to prevent vibration from being transmitted from the connecting pipe 220 to the base 100. The noise-reducing and suction-stabilizing breast pump also includes a pipe connector 500 movably connected to the base 100. The pipe connector 500 communicates with the connecting pipe 220 and has a plug hole 510 on its other side. The pipe connector 500 is movably connected to the base 100 to reduce vibration and noise transmitted to the breast pump and to connect the connecting pipe 220 and the pump body 210. The pipe connector 500 also has a detection hole 520, which connects to a negative pressure detection pipe 530 for negative pressure detection. It also includes a milk suction tube and a milk suction shield that mate with the plug hole 510 to achieve milk suction. The pump body assembly 200 includes two symmetrically arranged pump bodies 210. The symmetrical arrangement of the two pump bodies 210 can offset some of the vibrations in opposite directions, thereby reducing vibration and noise.

[0037] See appendix Figures 7-8 The device also includes a handle 120, with hinged portions 121 at both ends. The base 100 has hinge holes that mate with the hinged portions 121. Each hinge hole has a limiting block 130, and each hinged portion 121 has a protrusion 122 that mates with the limiting block 130. This design allows the handle 120 to be fixed in its natural falling position, preventing it from contacting the base 100. This avoids the handle 120 vibrating and colliding with the base 100 during the operation of the noise-reducing and stable breast pump, further enhancing the shock absorption and noise reduction effect.

[0038] See appendix Figure 9 The base 100 has a shock-absorbing ring 110 on its outer bottom surface. The area of ​​the support column 420 projected onto the outer bottom surface of the base 100 overlaps with the shock-absorbing ring 110, thereby reducing vibration and noise between the base 100 and the support surface. The support surface can be a flat surface such as a desktop or coffee table.

[0039] See appendix Figures 10-11 The base 100 is provided with an upper shell 600, which includes an outer shell 610 and an inner shell 620. By setting a double-layered outer shell 610 and inner shell 620, vibration and noise are reduced. Furthermore, a hollow layer is provided between the outer shell 610 and the inner shell 620 to further reduce vibration and noise.

[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
