Description

Technical Field

[0001] The utility model relates to the technical field of breast pumps, in particular to an electric breast pump host. Background Art

[0002] An electric breast pump is a device used to assist mothers in sucking milk, and is mainly composed of an electric breast pump main unit that can generate gas negative pressure, a breast pump terminal with a horn cover, and a connecting pipeline that connects the electric breast pump main unit to the breast pump terminal through an air path. During operation, the air pump on the electric breast pump main unit works to generate negative pressure, and the solenoid valve on the electric breast pump main unit controls the connection of the connecting pipeline, so that the gas pressure acting on the horn cover by the breast pump terminal changes, thereby acting on the mother's chest to assist in negative pressure sucking. The structure is as follows: the Chinese utility model "electric breast pump" with announcement number CN207575490U includes a main unit, an air pipe, and a "breast pump terminal" composed of a three-way assembly, a milk bottle, and a breast pump cover.

[0003] Since the components used to generate negative pressure on the main unit of the electric breast pump are mainly air pumps, and the components used to control pressure and pipeline connection are mainly solenoid valves, they will generate large noise and vibration when working, which will have a great impact on the user's use. For this reason, industry personnel have proposed more noise reduction and shock absorption designs, such as the Chinese utility model "An electric breast pump main unit and an electric breast pump" with announcement number CN208756640U. The air pump is coated with a shock absorbing device, which can reduce the vibration of the air pump during operation. The shock absorbing device is a cage-type shock absorbing suspension, which is made of soft silicone. A noise reduction device is connected to the exhaust port of the air pump, and the noise reduction device is composed of a noise reduction hose and a noise reduction ball.

[0004] Although the cage-type shock-absorbing suspension can reduce the vibration of the air pump, and the noise-reducing hose and noise-reducing ball can reduce the exhaust noise of the air pump, the vibration and noise generated by the solenoid valve and the weak noise generated by other parts of the air pump will still be directly output, causing a greater impact on user noise, which needs to be further improved.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] See also Figure 1-4 An electric breast pump host comprises a host housing 1, on which a control unit 2, an air pump 3 and a connecting pipe assembly 4 are arranged. The control unit 2 comprises a solenoid valve 21. A shock-absorbing box 5 is also installed in the host housing 1, and a solenoid valve holder 51 for holding the solenoid valve 21 and an air pump holder 52 for holding the air pump 3 are arranged in the shock-absorbing box 5, and a sound insulation cover 6 covering the opening of the shock-absorbing box 5 is arranged on the shock-absorbing box 5.

[0030] The shock-absorbing box 5 can be made of elastic material so that the shock-absorbing box has shock-absorbing performance, for example, it can be made of TPE material.

[0031] The connecting pipe assembly 4 is used to connect the gas port of the electromagnetic valve 21 to the gas port of the air pump 3, and to connect the gas port of the electromagnetic valve 21 to the outside of the main housing 1, so as to be connected to the breast pump terminal (not shown), and to provide negative pressure to the breast pump terminal when the air pump 3 is working and the electromagnetic valve 21 is controlled to be turned on, so as to smoothly assist the mother to suck milk. The shock-absorbing box 5 and / or the soundproof cover are provided with a channel suitable for the connecting pipe assembly 4 to pass through.

[0032] like Figure 1 , 4 As shown, the connecting pipe assembly includes a first connecting pipe 41 for connecting the first gas port of the solenoid valve 21 with the gas port of the air pump 3, and the connecting pipe assembly also includes a second connecting pipe 42 connected to the second gas port of the solenoid valve 21, and the second connecting pipe 42 is connected to the outside of the main body housing 1 or is connected to the outside of the main body housing through at least one intermediate channel.

[0033] The design accommodates and holds the solenoid valve 21 and the air pump 3 through the shock-absorbing box 5, so that the vibrations generated by the air pump 3 and the solenoid valve 21 are absorbed by the shock-absorbing box 5, thereby effectively reducing the vibrations transmitted to the main housing 1. The sound insulation cover 61 covers and soundproofs the shock-absorbing box 5, so that the noises generated by the air pump 3 and the solenoid valve 21 in the shock-absorbing box 5 are effectively isolated, so that the vibrations and noises finally output to the outside of the main housing 1 can be effectively reduced, reducing the impact of vibrations and noise on users during use, and the shock-absorbing box 5 and the sound insulation cover 6 can form a protective structure to effectively protect the solenoid valve 21 and the air pump 3 located therein, thereby improving practicality.

[0034] like Figure 3 As shown, the soundproof cover 6 covers the opening of the shock-absorbing box 5 so that the shock-absorbing box 5 is formed with a box proximal end 5 a close to the soundproof cover 6 and a box distal end 5 b away from the soundproof cover 6 .

[0035] The host housing 1 is provided with a stopper 11 for stopping the side of the soundproof cover away from the far end of the box. The host housing 1 is provided with a fixing assembly 12 for connecting the near end 5a of the box, wherein the fixing assembly 12 is connected to the near end 5a of the box in a direction in which the shock-absorbing box presses the soundproof cover against the stopper. The host housing 1 is also connected with a positioning frame 13 for holding the far end 5b of the box.

[0036] like Figure 3 , 4 As shown, the positioning frame 13 includes a first stopper 131 for stopping the side of the box body distal end 5b away from the sound insulation cover, and a second stopper 132 for stopping the side of the box body distal end 5b adjacent to the side away from the sound insulation cover.

[0037] like Figure 2 As shown, the fixing assembly 12 includes a screw hole column 121 formed in the main body housing 1, and a screw 122 threadedly engaged with the screw hole column 121. A connecting block 53 is formed on the outer side of the proximal end 5a of the box body, and a through hole is formed on the connecting block 53 to engage with the stem of the screw 122. The stem of the screw 122 passes through the through hole along the direction in which the shock-absorbing box body 5 presses the sound insulation cover 6 against the stopper 11, and is threadedly engaged with the screw hole column 121. When the screw 122 is continuously tightened, the shock-absorbing box body 5 presses the sound insulation cover 6 against the stopper 11.

[0038] Preferably, the soundproof cover 6 is made of elastic material. For example, it is made of TPE material. In addition to the function of cooperating for noise reduction, when used in combination with the above-mentioned fixing assembly 12 and the positioning frame 13, the soundproof cover 6 also enables the solenoid valve 21 and the air pump 3 located in the shock-absorbing box 5 to have better impact resistance. For example, when the main unit of the electric breast pump falls, it can produce a better buffering effect, so that the damage to the solenoid valve 21 and the air pump 3 located in the shock-absorbing box 5 can be reduced.

[0039] The combination of the above-mentioned resisting portion 11, fixing component 12 and positioning frame 13 can effectively prevent the sound insulation cover 6 from being separated from the sound insulation covering the shock absorption box 5 when being used to fasten the sound insulation cover 6 and the shock absorption box 5. When the sound insulation cover 6 is made of elastic material, the shock absorption box 5 can be first joined to the sound insulation cover 6 by the fixing component 12 so that the sound insulation cover 6 is pressed by the shock absorption box 5 and the resisting portion 11 to produce elastic deformation, and then the positioning frame 13 is installed to position and hold the shock absorption box 5. In daily use and after the main body shell 1 is dropped and hit, the sound insulation cover 6 can be kept in a tightly covered state relatively stably, thereby effectively ensuring its sound insulation effect.

[0040] Preferably, when the sound insulation cover 6 is made of elastic material, a retaining component can be further provided on one side of the sound insulation cover corresponding to the internal space of the shock absorbing box to assist in retaining the air pump and / or the electromagnetic magnet, thereby assisting in shock absorption.

[0041] Preferably, the air pump retaining frame 52 includes a plurality of supporting pads 521 for holding the motor of the air pump 3. The plurality of supporting pads 521 are arranged at intervals along the axial direction of the motor, and a heat dissipation space 522 is provided between adjacent supporting pads 521 to ensure a better heat dissipation effect for the motor of the air pump 3.

[0042] Preferably, a card slot 54 is formed on the shock-absorbing box body 5 , and a card block 61 that cooperates with the card slot 54 is formed on the sound insulation cover 6 .

[0043] like Figure 1 As shown, the main body shell 1 is composed of two parts. The first part of the main body shell 1a is located at the lower part, and is mainly used to install components with large weight or volume, such as installing air pumps, solenoid valves, connecting pipe assemblies, and possibly additional batteries and other components. The first part of the main body shell 1a is in the shape of a tower that gradually shrinks from bottom to top, and can form a relatively stable base. The second part of the main body shell 1b is set at the top of the tower of the first part of the main body shell 1a, and is mainly used to install control components, such as circuit boards, display panels, operating buttons and other components. The outer side of the second part of the main body shell 1b can form a panel to facilitate users to operate or view displayed information.

[0044] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
