Description

Technical Field

[0001] The utility model relates to the technical field of breast pumps, in particular to a breast pump host with heat dissipation capability. Background Art

[0002] A breast pump is a must-have item for lactating women, and is mainly used to squeeze out breast milk accumulated in the mammary glands. In the prior art, a vacuum pump is often used as the main component of a breast pump; when the vacuum pump is working, its valve plate will hit the valve seat and the support member, thereby generating a certain amount of noise, which will affect the user's experience when using the breast pump.

[0003] To this end, the Chinese patent application number 202321029084.2 discloses a "double-sided breast pump host", which uses a piezoelectric pump instead of a traditional vacuum pump to achieve the extraction of breast milk in a silent environment. However, long-term use of the piezoelectric pump will generate heat. When the working temperature of the piezoelectric pump exceeds 70°C, the suction force of the piezoelectric pump will decrease. Although the patent adopts the method of using die-casting to dissipate heat from the piezoelectric pump body, the heat derived from the die-casting still exists in the closed breast pump shell and cannot be effectively dissipated.

[0008] The breast pump main unit with heat dissipation capability provided by the utility model preferably further comprises a three-way pipe and two solenoid valves;

[0009] The three-way pipe and the two solenoid valves are arranged inside the housing;

[0021] The above technical solution has the following advantages or beneficial effects:

[0022] The breast pump main unit with heat dissipation capability provided by the utility model is provided with three piezoelectric pumps, which are connected in series through pipelines, and the suction ports of the three piezoelectric pumps in series are connected to two horn covers for sucking breast milk, and the breast milk stored in the breast is sucked out through the suction force generated by the piezoelectric pumps; at the same time, the piezoelectric pump is formed by bending and deforming the piezoelectric vibrator, so that the space inside the pump is contracted, thereby generating suction force, and the piezoelectric pump is noiseless when working, so that the work of sucking breast milk can be completed in silence, and the user experience is taken into consideration;

[0023] The three piezoelectric pumps are all close to the shell, and the shell is made of heat-conducting metal.

By providing a soundproof cabin outside the solenoid valves, the noise generated when the solenoid valves are working can be reduced, so that breast milk can be extracted in a silent environment, thereby improving the user experience.

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0034] Embodiment 1:

[0035] like Figures 1 to 6 As shown, a breast pump main unit with heat dissipation capability provided by Embodiment 1 of the utility model comprises a housing 1 and a negative pressure suction assembly 11; a space is provided inside the housing 1; the negative pressure suction assembly 11 comprises a plurality of piezoelectric pumps 111; all the piezoelectric pumps 111 are arranged in series through pipelines; all the piezoelectric pumps 111 are fixed inside the housing 1; the air inlet of the negative pressure suction assembly 11 is connected to the outside of the housing 1;

[0036] The piezoelectric pump 111 is closely attached to the housing 1 ; the housing 1 is made of heat-conducting metal.

[0037] When using the breast pump main unit with heat dissipation capability provided in Example 1 of the utility model, the air inlet of the negative pressure suction component 11 in the breast pump main unit is connected to the external speaker cover through a pipe; all the piezoelectric pumps 111 are energized to have a certain suction force, so as to absorb breast milk in the breast through the external speaker cover.

[0038] The breast pump main unit with heat dissipation capability provided in Example 1 of the utility model is provided with a plurality of piezoelectric pumps 111; all the piezoelectric pumps 111 are arranged inside the housing 1; all the piezoelectric pumps 111 are arranged in series through pipelines; when the breast pump main unit is used to suck breast milk, the piezoelectric pumps 111 after being energized will generate suction, and a plurality of piezoelectric pumps 111 connected in series can achieve a stronger suction effect; at the same time, since the piezoelectric pumps 111 are formed by the bending and deformation of the piezoelectric vibrator, the space inside the pump is contracted, thereby generating suction, and the piezoelectric pumps 111 are noiseless when working, so that the work of sucking breast milk can be completed silently, while taking into account the user's experience.

[0039] In the breast pump main unit with heat dissipation capability provided by Example 1 of the utility model, the piezoelectric pump 111 is closely attached to the shell 1, and the shell 1 is made of heat-conducting metal. This structure enables the breast pump main unit to have good heat dissipation performance. When the breast pump main unit is working, the piezoelectric pump 111 closely attached to the shell 1 will generate a large amount of heat, which will cause the piezoelectric pump to lose its working efficiency due to the high temperature. The piezoelectric pump 111 is closely contacted with the shell 1, so that the shell 1 made of heat-conducting metal can transfer the heat on the piezoelectric pump 111 to the shell 1, and then the shell 1 dissipates this part of heat into the air, which effectively solves the problem that the breast pump main unit generates heat internally due to long-term use and cannot effectively dissipate heat, thereby realizing long-term stable operation of the breast pump main unit. At the same time, when the breast pump shell 1 is directly touched by the hand, the hand is prevented from being scalded by the high temperature generated by the piezoelectric pump 111.

[0040] The breast pump main unit with heat dissipation capability provided in Embodiment 1 of the utility model preferably further comprises a three-way pipe 12 and two solenoid valves 13;

[0041] The three-way pipe 12 and two solenoid valves 13 are arranged inside the housing 1;

[0042] The three-way pipe 12 includes an outlet pipe 121 and two inlet pipes 122;

[0043] The air outlet pipeline 121 is connected to the air inlet of the negative pressure suction component 11; the two air inlet pipelines 122 are respectively connected to the two solenoid valves 13;

[0044] The solenoid valve 13 is provided with a suction port 131 for being connected to the outside of the housing 1 ; the suction port 131 is connected to the air intake pipeline 122 ; the solenoid valve 13 controls the opening and closing of the suction port 131 .

[0045] When the breast pump is working, in order to allow the breast pump to suck breast milk from two breasts, two solenoid valves 13 are respectively connected to the two air inlet pipes 122 of the three-way pipe 12, and the suction ports 131 on the solenoid valves 13 at both ends are opened and closed cyclically by energizing or de-energizing the solenoid valves 13 at both ends, so that the suction ports of the negative pressure suction component 11 alternately suck breast milk from the two breasts; at the same time, due to the opening and closing of the solenoid valves 13, the suction ports 131 on the solenoid valves 13 are always under the same suction force, and when alternately sucking breast milk from the two breasts, the suction forces of the suction ports 131 on the solenoid valves 13 at both ends are the same.

[0046] In the breast pump main unit with heat dissipation capability provided in Embodiment 1 of the utility model, preferably, the two solenoid valves 13 are provided with a cabin 14 for blocking the noise generated by the solenoid valves 13; the cabin 14 is fixed to the housing 1;

[0047] When the solenoid valve 13 is working, a regular sound will be generated. By arranging a soundproof cabin 14 outside the solenoid valve 13, the noise generated by the solenoid valve 13 when working can be reduced, so that breast milk can be sucked in a silent environment, thereby improving the user experience.

[0048] In the breast pump host with heat dissipation capability provided in Embodiment 1 of the utility model, preferably, the number of piezoelectric pumps 111 used is three;

[0049] Considering that the effective suction force of a single piezoelectric pump 111 is insufficient, in order to meet the suction force condition of 35 kPa to fully absorb breast milk in the breast, using three piezoelectric pumps 111 can give the user a better experience.

[0050] The breast pump host with heat dissipation capability provided in Embodiment 1 of the present utility model preferably further includes a control panel 15;

[0051] The control panel 15 is fixed to the top of the housing 1 and is integrally formed with the housing 1;

[0052] The control board 15 is electrically connected to the two solenoid valves 13; the control board 15 is electrically connected to all the piezoelectric pumps 111;

[0053] When the breast pump is in use, commands are sent to the two solenoid valves 13 and all the piezoelectric pumps 111 through the control panel 15, so that the negative pressure suction component 11 has suction, and the two solenoid valves 13 can be regularly powered on and off under the command; thereby, the suction port of the negative pressure suction component 11 is connected to a suction port 131, and when the breast milk in the two breasts is alternately sucked, the suction of the suction ports 131 at both ends is kept the same.

[0054] The breast pump main unit with heat dissipation capability provided in Embodiment 1 of the present utility model preferably further comprises a battery 16;

[0055] The battery 16 is fixed inside the housing 1;

[0056] The battery 16 is electrically connected to the control board 15; the battery 16 is electrically connected to the two solenoid valves 13; the battery 16 is electrically connected to all the piezoelectric pumps 111;

[0057] When the breast pump is in use, the control board 15, the two solenoid valves 13 and all the piezoelectric pumps 111 are powered by the battery 16, so that the control board 15 can drive the two solenoid valves 13 and all the piezoelectric pumps 111 to work.

[0058] In summary, the present invention provides a breast pump host with heat dissipation capability, which can solve the problem in the prior art that heat is generated due to long-term use of a piezoelectric pump and the heat cannot be effectively dissipated, and the heat generated by the piezoelectric pump can be dissipated into the air.
