Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric breast pump technology, and in particular to a handheld electric breast pump. Background Technology
[0002] Handheld electric breast pumps are a powerful tool for breastfeeding mothers. They mainly consist of a bell, bottle, connecting tube, and motor. They work by using negative pressure to simulate a baby's sucking process, drawing breast milk from the breast. They are convenient and easy to use; simply turn on the switch to easily pump milk without manual operation, saving time and energy. Moreover, the suction power is stable and adjustable, usually with multiple suction levels. Mothers can find the most suitable suction power based on their comfort and milk production, effectively improving pumping efficiency.
[0003] Most commercially available products in the current technology only focus on the milk pumping operation and do not integrate a heating module. In cold weather, the milk pumped by mothers is easy to cool down and requires the use of additional equipment such as bottle warmers to heat it up. The process is cumbersome and can easily cause secondary contamination. At the same time, the grip design of traditional breast pumps is often relatively simple, only able to hold the milk storage bottle. Holding it for a long time can easily cause hand fatigue. Therefore, we propose a handheld electric breast pump. Utility Model Content
[0004] The purpose of this invention is to provide a handheld electric breast pump to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a handheld electric breast pump, comprising a milk storage bottle, a heating and insulation mechanism, and a handheld mechanism. The handheld mechanism includes an elastic retaining ring, and an arc-shaped handle is fixedly installed on the outer wall of the elastic retaining ring. The heating and insulation mechanism includes an insulation sleeve with openings at both ends. An elastic band is fixedly installed on the upper end of the insulation sleeve. Velcro is fixedly installed at both opening and closing points of the insulation sleeve. A PTC heating element is connected to the insulation sleeve through a mounting groove. A power cord is connected to the PTC heating element through a power port.
[0006] As a preferred embodiment, the upper end of the milk storage bottle is threaded with a flow guide component, a horn cover is inserted into the right side of the flow guide component, and a power component is inserted into the upper end of the flow guide component.
[0007] As a preferred embodiment, the elastic band is sleeved on the outer wall of the milk storage bottle near the upper end, the insulation sleeve is sleeved on the outer wall of the milk storage bottle by Velcro, the mounting groove is opened inside the insulation sleeve, the PTC heating element is inserted into the mounting groove, and the outer wall of the insulation sleeve has a through groove.
[0008] As a preferred embodiment, the wires of the PTC heating element are electrically connected to the power-on port, the power-on port is fixedly installed inside the slot, and the power cord is plugged into the power-on port.
[0009] As a preferred embodiment, an anti-slip pad is fixedly installed on the inner wall of the elastic retaining ring, the elastic retaining ring is snapped onto the outer wall of the power assembly, a finger groove is provided on one side of the outer wall of the arc-shaped grip, a thumb retaining sleeve is fixedly installed on the other side of the arc-shaped grip, and a threaded hole is passed through the end of the arc-shaped grip away from the elastic retaining ring.
[0010] As a preferred embodiment, a threaded sleeve is internally threaded into the threaded hole, an anti-loosening cap is fixedly installed at the upper end of the threaded sleeve, a threaded rod is internally threaded into the threaded sleeve, and a silicone pad is fixedly installed at the bottom of the threaded rod.
[0011] The technical effects and advantages of this utility model are as follows:
[0012] 1. The elastic band and insulating sleeve securely wrap the PTC heating element tightly around the outer wall of the milk storage bottle, easily adapting to different sizes of milk storage bottles within a certain range. In cold weather, simply connect the power cord, and the PTC heating element will immediately start operating, fully utilizing its unique performance to quickly generate heat. At the same time, the insulating sleeve effectively reduces heat loss. The two work together to efficiently heat the milk in the milk storage bottle and maintain a suitable temperature for a long time. After pumping, the heated milk can be used directly to feed the baby without any further processing, bringing great convenience to mothers.
[0013] 2. The elastic retaining ring in the hand-held mechanism allows for a convenient and secure connection between the curved handle and the electric breast pump. The anti-slip pad effectively prevents the handle from falling off during use, enhancing operational safety. In actual use, the ergonomic design of the thumb retainer and finger groove perfectly fits the user's hand, greatly improving comfort. Furthermore, by rotating the threaded rod, it can be smoothly screwed into the threaded sleeve, thereby pushing the silicone pad tightly against the user's body. This cleverly uses body support to distribute the burden on the hand, significantly reducing hand fatigue caused by prolonged holding. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Example 1:
[0025] Please see the appendix Figure 1 - Appendix Figure 6A handheld electric breast pump includes a milk storage bottle 1, a heating and insulation mechanism 5, and a handheld mechanism 6. The handheld mechanism 6 includes an elastic retaining ring 602, and an arc-shaped handle 601 is fixedly installed on the outer wall of the elastic retaining ring 602. The heating and insulation mechanism 5 includes an insulation sleeve 501 with openings at both ends. An elastic band 505 is fixedly installed on the upper end of the insulation sleeve 501. Velcro closures 502 are fixedly installed at the opening and closing points of the insulation sleeve 501. A PTC heating element 506 is connected to the insulation sleeve 501 through a mounting groove 503. The PTC heating element 506 is connected to a power cord 508 through a power port 507. A flow guide assembly 2 is threadedly connected to the upper end of the milk storage bottle 1. A horn cover 3 is inserted into the right side of the flow guiding component 2, and a power component 4 is inserted into the upper end of the flow guiding component 2. An elastic band 505 is sleeved on the outer wall of the milk storage bottle 1 near the upper end. The heat preservation sleeve 501 is sleeved on the outer wall of the milk storage bottle 1 by Velcro 502. The mounting groove 503 is opened inside the heat preservation sleeve 501. The PTC heating element 506 is inserted into the mounting groove 503. A slot 504 runs through the outer wall of the heat preservation sleeve 501. The wire of the PTC heating element 506 is electrically connected to the power port 507. The power port 507 is fixedly installed inside the slot 504. The power cord 508 is inserted into the power port 507.
[0026] The insulation sleeve 501 is opened and closed via Velcro 502. An elastic band 505 is fixedly installed at the upper end of the insulation sleeve 501. When the insulation sleeve 501 is opened, the elastic band 505 stretches. The PTC heating element 506 is existing technology. The PTC heating element 506 is made of a thermistor material with a positive temperature coefficient. When the PTC heating element 506 is energized, current flows through the heating element. Due to the resistance, electrical energy is converted into heat energy, and the temperature of the heating element begins to rise. As the temperature rises, the resistance of the PTC material gradually increases. According to Ohm's law, under constant voltage, increased resistance leads to decreased current, thus reducing heating power. When the temperature rises to the Curie temperature of the PTC heating element 506 (45 degrees Celsius), the resistance increases sharply, the current decreases significantly, and the heating power also decreases substantially. At this point, the heat generated by the heating element and the heat dissipated to the surrounding environment reach equilibrium, and the temperature no longer rises, thus achieving automatic temperature control.
[0027] Specifically, the elastic band 505 and the insulating sleeve 501 can wrap the PTC heating element 506 around the outer wall of milk storage bottles 1 of different sizes within a certain range. When the weather is cold, the PTC heating element 506, through its own performance, can heat and keep the milk in the milk storage bottle 1 warm after the power cord 508 is powered on, in conjunction with the insulating sleeve 501. After the milk is finished, there is no need to heat it up, and it can be given directly to the baby to drink.
[0028] Example 2:
[0029] Please see the appendix Figure 1 Appendix Figure 7 and attached Figure 8 Furthermore, based on Embodiment 1, an anti-slip pad 603 is fixedly installed on the inner wall of the elastic retaining ring 602, the elastic retaining ring 602 is snapped onto the outer wall of the power assembly 4, a finger groove 605 is provided on one side of the outer wall of the arc-shaped grip 601, a thumb retaining sleeve 604 is fixedly installed on the other side of the arc-shaped grip 601, a threaded hole 606 is passed through the end of the arc-shaped grip 601 away from the elastic retaining ring 602, a threaded sleeve 607 is threadedly connected inside the threaded hole 606, an anti-detachment cap 608 is fixedly installed on the upper end of the threaded sleeve 607, a threaded rod 609 is threadedly connected inside the threaded sleeve 607, and a silicone pad 610 is fixedly installed at the bottom of the threaded rod 609.
[0030] The finger groove 605 and thumb retainer 604 allow the user's hand to fit perfectly in the curved grip 601, improving comfort. The elastic retaining ring 602, after being engaged with the power component 4, works with the anti-slip pad 603 to prevent it from easily coming off, ensuring stability.
[0031] Specifically, the elastic retaining ring 602 in the hand-held mechanism 6 can connect the arc-shaped handle 601 to the electric breast pump, and the anti-slip pad 603 prevents it from falling off. During use, the thumb retaining sleeve 604 and the finger groove 605 improve the user's comfort. At the same time, the rotation of the threaded rod 609 in the threaded sleeve 607 allows the silicone pad 610 to press against the user's body, reducing the weight of the hand.
[0032] Working principle of this utility model: This utility model is a handheld electric breast pump. First, the elastic band 505 is placed on the outer wall of the milk storage bottle 1 near the upper part. Then, the insulation sleeve 501 is placed on the outer wall of the milk storage bottle 1 using Velcro 502. Next, the elastic retaining ring 602 is fastened to the outer wall of the power component 4. After adjusting to a comfortable usage posture, the user inserts their thumb into the thumb retaining sleeve 604 and grips the arc-shaped handle 601. According to usage needs, the threaded rod 609 can be rotated, causing the threaded rod 609 to rotate from the threaded... Unscrew the threaded sleeve 607 until the silicone pad 610 is pressed against your body. Alternatively, rotate the threaded sleeve 607 upwards along the threaded hole 606 to make the bottom of the arc-shaped handle 601 protrude. Once ready, you can start pumping milk. At the same time, connect the power cord 508 to a power bank or other power supply device to make the PTC heating element 506 start heating up until it reaches its Curie temperature of 45 degrees Celsius, then maintains a constant temperature to keep the milk in the milk storage bottle 1 warm. After pumping, simply remove the milk storage bottle 1 and give it to the baby to drink.
