Description

TECHNICAL FIELD

[0001] The present application relates to a breast pump chair. BACKGROUND

[0002] A breast pump is a tool to help a mother to suck out milk from the breast, and the sucked milk can be stored in a milk storage container. Through regular use, it not only helps to dredge the mammary glands and maintain milk volume, but also allows the mother to continuously feed the infant with stored breast milk when direct breastfeeding is not possible.

[0003] There are various breast pumps on the market, which can be divided into two categories according to the power source: one is a manual breast pump, which generates suction force by pressing the handle with the hand; the other is an electric breast pump, which relies on a motor to generate suction force. However, whether it is a manual breast pump or an electric breast pump, during use, one hand usually needs to hold the milk collection bottle body to provide gravitational support to the milk collection bottle body to keep the breast pump stable. Based on the conventional 20-30 minute pumping time, it is quite tiring to hold the milk collection bottle body with the hand for a long time, and if the hand is not held tightly, the breast cup may not fit the breast completely, which may cause air leakage and make it difficult to pump milk.

[0004] There are breast pumps on the market that can be operated completely without holding the hand, which rely on special clothes to support the breast pump, but they can only be used for electric breast pumps.

[0005] Therefore, there is a market demand for a lactation aid, a breast pump chair with a breast pump support that can provide support for both manual and electric breast pumps to help lactating mothers better express milk. SUMMARY

[0020] As attached Figure 1As shown, a breast pump chair is used as an auxiliary product during breastfeeding. When a breastfeeding mother sits on the seat 94 of the breast pump chair, she places the milk collection bottle of the breast pump in the cup holder 10 of the breast pump stand, which can help the breastfeeding mother to express milk better.

[0021] In the description of this invention, it should be noted that the directions or positional relationships indicated by terms such as "up," "down," "left," "right," "front," and "back" are based on the appendix. Figure 1 , 2 The orientation or positional relationship shown in the usage state, defining the position of seat 94 as "front" and the position of table 97 as "rear," is for the convenience of describing the invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, directional words such as "up," "down," "left," "right," "front," and "rear" should not be construed as limitations on the invention.

[0022] The detailed information about breast pump chairs is as follows: As attached Figure 1 -Appendix Figure 5 As shown, a breast pump chair includes a chair frame and a seat 94 located at the front, as attached. Figure 1 Appendix Figure 6 -Appendix Figure 10 As shown, it also includes a breast pump holder mounted on the chair frame. In use, the breastfeeding mother sits facing backward on seat 94 of the breast pump chair, places the milk collection cup of the breast pump in the cup holder 10 of the breast pump holder, and adjusts the position of the cup holder 10 by adjusting the linkage 20 to suit the individual body position of the breastfeeding mother, facilitating milk expression.

[0023] In this embodiment, the human body can not only sit on the seat 94, but also choose to lean forward at a certain angle, such as 15°-45° facing the table 97, and express milk at such an angle.

[0024] In this embodiment, the chair frame includes an upper support frame 91 located at the rear. A forward-tilting backrest 95 is fixedly mounted on the upper support frame 91, and is either height-adjustable via a pin or detachable via a rope. The forward-tilting backrest 95 is located in front of the breast pump bracket, and the seat 94 is located in front of the bottom side of the forward-tilting backrest 95. (See attached image) Figures 1-3 As shown, milk-suction spaces 951 are formed on the left and right sides of the upper part of the forward-tilting backrest 95, and breast support parts 952 for supporting the breasts are formed on the left and right sides of the lower part. The milk-suction space 951 is formed above each breast support part 952. After the milk collection cup of the breast pump is placed in the cup holder 10 of the breast pump stand, the horn cover of the breast pump faces the corresponding milk-suction space 951.

[0025] The forward-leaning backrest 95 forms an angle α with the horizontal plane. The angle α is set within the range of 40°-80°, such as 60° or 75°. When a breastfeeding mother sits on the seat 94 and leans towards the table 97, her upper body presses against the forward-leaning backrest 95. The body is at an angle of 60° or 75° relative to the horizontal plane to express milk.

[0026] In this embodiment, a fixed angle b is formed between the forward-leaning backrest 95 and the seat 94, with the angle b ranging from 90° to 110°. For example, angle b is 105°. The angle α formed between the forward-leaning backrest 95 and the horizontal plane is adjustable. (See attached...) Figure 2 , 4 As shown in Figure 5, the chair frame includes: The bottom support 93 is located at the bottom. A main support frame 92 is provided, and the main support frame 92 is connected to the bottom support frame 93 via a pivotal main frame rotating shaft X901 extending to the left and right. A seat 94 is installed at the front of the main support frame 92. The bracket angle adjustment device 99 is set between the main support frame 92 and the bottom support 93 to adjust the angle between them. The angle α formed between the forward tilting plate 95 and the horizontal plane is adjusted by adjusting the bracket angle adjustment device 99. The aforementioned upper support frame 91 is mounted at the rear of the main support frame 92 in an adjustable manner, as shown in the attached figure. Figure 1 As shown, a breast pump bracket is installed on the upper support frame 91. The breast pump bracket includes a cup holder 10 for placing the breast pump milk collection cup and a connecting rod frame 20 that is adjustable and used to support the cup holder 10 and is installed on the upper support frame 91.

[0027] In this embodiment, the main support frame 92 is a rigid whole, as shown in the attached figure. Figure 4 , 5 As shown, it includes a main frame bottom section 922 located at the bottom, a main frame rear section 923 located at the rear and extending upward from the rear side of the main frame bottom section 922, a main frame front section 921 located at the front and extending upward from the front side of the main frame bottom section 922, an upper support frame 91 installed on the upper part of the main frame rear section 923, and a seat 94 installed on the upper part of the main frame front section 921.

[0028] The base support 93 includes a shell 931 located at the top, and the front part of the main frame bottom section 922 is pivotally connected to the shell 931 via the main frame pivot X901.

[0029] The bracket angle adjustment device 99 includes an adjustment handle 991 rotatably mounted on the top of the housing 931 about an adjustment shaft X902, an upper threaded sleeve 994 fixed inside the housing 931, and a lower threaded sleeve 993 pivotally connected to the rear of the bottom section 922 of the main frame. The adjustment handle 991 has a threaded rod 992 that slides only axially and extends downwards. The centerline of the threaded rod 992 coincides with the axis of the adjustment shaft X902. The threaded rod 992 is threadedly inserted into the upper threaded sleeve 994 and the lower threaded sleeve 993, with the threads of the upper threaded sleeve 994 and the lower threaded sleeve 993 being opposite. Rotating the adjustment handle 991 in either the forward or reverse direction controls the threaded rod 992 to rotate around the adjustment shaft X902. Rotating the pivot X902 causes the threaded rod 992 to move relative to the upper threaded sleeve 994 and the lower threaded sleeve 993, thereby adjusting the angle of the rear of the main support frame 92 relative to the pivot X901 of the main frame on the bottom support 93, raising or lowering it. This adjusts the angle α between the forward tilting plate 95 and the horizontal plane. If the breastfeeding mother's breasts are full or sagging, adjusting the angle α between the forward tilting plate 95 and the horizontal plane to 45° or 60° will help the breast pump's bell cover fit the areola better, improving the fit of the breast pump, reducing air intake, and also assisting milk flow with gravity. The forward tilting plate 95 supports the upper body, effectively preventing excessive strain on the lower back.

[0030] The upper support frame 91 is also equipped with a table 97 that extends backward, and a waist belt 96 located below the forward tilting back plate 95 is also installed on the upper support frame 91. A headrest 98 located above the forward tilting back plate 95 is also installed on the upper part of the upper support frame 91.

[0031] When using the product during breastfeeding, adjust the forward-leaning backrest 95 to a suitable angle, sit on the seat 94, lean your upper body against the forward-leaning backrest 95, and use the waist strap 96. Place the breast pump on the breast pump stand and use the pump. Your head can also rest on the headrest 98 for safety and to aid milk flow. The forward-leaning backrest 95 supports the upper body, and the headrest 98 supports the head, effectively preventing fatigue in the lower back and head. Books or mobile phones can be placed on the table 97.

[0032] Breast pump stand, detailed information is as follows: A breast pump stand, as shown in the attached image Figure 1 Appendix Figure 6 -Appendix Figure 10 As shown, it includes a cup holder 10 for holding the milk collection cup of a breast pump and a connecting rod 20 for supporting the cup holder 10. (See attached image) Figure 6 As shown, the bottom of the linkage 20 is mounted on the upper support frame 91 of the chair.

[0033] Joint Linkage Frame 20: The linkage 20 is adjustable and is equipped with a linkage angle locking device 30 to lock the linkage 20 in its adjusted state. By adjusting the linkage 20, the position of the cup holder 10 can be adjusted so that the milk collection cup of the breast pump can be placed in the cup holder 10, making the position of the milk collection cup conform to the body position of each mother.

[0034] As attached Figure 6 , 7 As shown in Figure 9, the linkage 20 in this embodiment includes two connecting rods connected end to end in sequence: an upper connecting rod 21 and a lower connecting rod 22 whose upper end is pivotally connected to the lower end of the upper connecting rod 21 via a second axis X22. A cup holder 10 is installed on the upper end of the upper connecting rod 21. A connecting rod angle locking device 30 is disposed between the lower end of the upper connecting rod 21 and the upper end of the lower connecting rod 22. After the connecting rod angle locking device 30 is locked, the upper connecting rod 21 and the lower connecting rod 22 cannot rotate around the second axis X22.

[0035] The linkage angle locking device 30 is applicable to any structure capable of controlling the locking or unlocking of two pivotally connected components. In this embodiment, as shown in the attached... Figure 7 As shown, the linkage angle locking device 30 includes a first toothed groove ring at the lower end of the upper linkage 21, a second toothed groove ring 32 at the upper end of the lower linkage 22, a locking tooth 33 that slides axially along the second axis X22, and a linkage unlocking button 31 (not shown) that is axially mounted at the lower end of the upper linkage 21 and abuts against one side of the locking tooth 33. It also includes a linkage lock elastic element, i.e., a linkage lock spring, abutting against the other side of the locking tooth 33. When locked, the linkage lock elastic element pushes the locking tooth 33 so that it simultaneously inserts into both the first toothed groove ring and the second toothed groove ring 32. When the connecting rod lock elastic element is overcome and the connecting rod unlock button 31 is pressed, the locking teeth 33 are pushed to completely disengage from the first toothed ring and fully enter the second toothed ring 32, thus unlocking the connecting rod angle lock device 30. The upper connecting rod 21 can be rotated arbitrarily relative to the lower connecting rod 22 around the second axis X22. When the connecting rod unlock button 31 is released, under the action of the connecting rod lock elastic element, the locking teeth 33 are pushed to simultaneously insert into the first toothed ring and the second toothed ring 32, restoring the lock.

[0036] As attached Figure 6 As shown, in this embodiment, the breast pump chair is installed on a chair. The linkage frame 20 also includes a base 23 that can be detachably and vertically mounted on the chair support frame 91 at different heights. In this example, to allow the lower linkage 22 to be adjusted both in angle and left and right, adapting to the body shape of breastfeeding mothers, the assembly structure is also simple. The cooperation between the base 23 and the lower linkage 22 is as follows: As attached Figure 1As shown, the base 23 includes two fixed crossbars 23a located on the left and right sides respectively, with their center lines coinciding. The outer circular surface of the fixed crossbars 23a is provided with an outer circumferential toothed ring. The lower end of the lower connecting rod 22 is provided with an assembly structure that can be detachably assembled onto an object, as shown in the attached figure. Figure 6 , 7 As shown in Figure 9, the assembly structure at the lower end of the lower connecting rod 22 is a ring seat 22a. An inner circumferential toothed ring 22b is provided on the inner circular surface of the ring seat 22a along the circumferential direction. The ring seat 22a can be axially inserted and removed onto the fixed crossbar 23a, and the inner circumferential toothed ring 22b meshes with the outer circumferential toothed ring. When adjusting the angle, the ring seat 22a is removed from the fixed crossbar 23a and adjusted to the required engagement angle. Then, the ring seat 22a is axially repositioned onto the fixed crossbar 23a at the appropriate position, and the engagement angle between the inner circumferential toothed ring 22b and the outer circumferential toothed ring is used for positioning. Simultaneously, it is suitable for the body shape of breastfeeding mothers in the left and right directions.

[0037] In this embodiment, the front-back and left-right positions of the cup holder 10 are adjusted by adjusting the position of the lower connecting rod 22 relative to the base 23 and / or adjusting the position of the upper connecting rod 21 relative to the lower connecting rod 22.

[0038] Regarding cup holder 10: To suit the structure of the above-mentioned linkage 20, see attached... Figures 1-5 As shown, the cup holder 10 in this embodiment includes a cup base 11 pivotally connected to the upper end of the upper connecting rod 21 via a first shaft X21, a cup holder 12 that can slide up and down on the cup base 11, and a height adjustment mechanism 50 disposed between the cup holder 12 and the cup base 11.

[0039] A cup holder angle locking device 40 is provided at the pivot point between the cup base 11 of the cup holder 10 and the upper end of the upper connecting rod 21. After adjusting the position of the cup holder 10 by adjusting the connecting rod bracket 20, the angle of the cup holder 10 relative to the upper connecting rod 21 is adjusted by unlocking the cup holder angle locking device 40, so that the cup holder 10 is basically vertical, conforming to the body position of mothers when breastfeeding. In this embodiment, as shown in the attached... Figure 6 , 7 As shown, the structure and operation principle of the cup holder angle locking device 40 are the same as those of the aforementioned link angle locking device 30. By pressing or releasing the cup holder unlock button, the cup holder angle locking device 40 can be unlocked or re-locked. When the cup holder angle locking device 40 is unlocked, the angle of the cup holder 10 relative to the upper link 21 can be adjusted.

[0040] Detailed structure of cup holder 12: Cup holder 12 includes a base 121, a cup wall 122 extending upward from the rear side of the base 121, and adjustment straps 123 at both ends connected to the left and right sides of the cup wall 122.

[0041] The cup wall 122 includes an upper cup wall 122a that can slide up and down on the cup holder 11, and a lower cup wall 122b that can slide up and down on the upper cup wall 122a. A base 121 is fixed to the lower edge of the lower cup wall 122b. A height adjustment mechanism 50 is located between the upper cup wall 122a and the cup holder 11, and a depth adjustment mechanism 60 is located between the upper cup wall 122a and the lower cup wall 122b. By unlocking the height adjustment mechanism 50, the relative vertical position of the upper cup wall 122a and the cup holder 11 can be adjusted, i.e., the height of the entire cup holder 12 relative to the connecting rod 20 can be adjusted. By unlocking the depth adjustment mechanism 60, the relative vertical position between the upper cup wall 122a and the lower cup wall 122b can be adjusted, i.e., the depth of the entire cup holder 12 can be adjusted.

[0042] Adjustable straps 123 are installed between the two side walls of the upper cup wall 122a and between the two side walls of the lower cup wall 122b. The adjustable straps 123 are snap-on straps, elastic bands, or Velcro straps with adjustable length. The base 121, cup wall 122, and adjustable straps 123 form a cup holder cavity with adjustable depth and width to accommodate milk collection cups of various heights, thicknesses, and sizes.

[0043] Regarding the height adjustment mechanism 50, see attached... Figure 8 As shown, the slide rails on both sides of the cup holder 11 are inserted into the slide grooves on both sides of the upper cup wall 122a. A cup holder button is slidably installed inside the cup holder 11. The spring inside the cup holder is not shown. The upper cup wall 122a has an upper cup wall channel extending in the vertical direction and multiple height locking grooves evenly distributed vertically and connected to the upper cup wall channel. The cup holder button has height locking teeth. When the height adjustment mechanism 50 is locked, the height locking teeth are inserted into the corresponding height locking grooves. Pressing the cup holder button against the spring inside the cup holder 11 causes the height locking teeth to retract from the corresponding height locking grooves and enter the upper cup wall channel. At this time, the height adjustment mechanism 50 is unlocked, and the upper cup wall 122a can be raised and lowered. Releasing the cup holder button causes the height locking teeth to re-lock into the corresponding height locking grooves under the action of the spring inside the cup holder 11.

[0044] Regarding the depth adjustment mechanism 60, see attached... Figure 10 As shown, the lower cup wall 122b is inserted upward into the upper cup wall 122a. The upper cup wall 122a has a cup holder button and a cup holder spring that slide horizontally. The lower cup wall 122b has multiple depth locking grooves that are evenly distributed vertically. The cup holder button has a locking ring that fits onto the lower cup wall 122b. When the depth adjustment mechanism 60 is locked, the locking ring is engaged in the corresponding depth locking groove. Pressing the cup holder button against the cup holder spring causes the locking ring to disengage from the corresponding depth locking groove. At this time, the depth adjustment mechanism 60 is unlocked, and the lower cup wall 122b can move up and down within the locking ring to adjust the depth of the receiving cavity. Releasing the cup holder button causes the locking ring to move into the corresponding depth locking groove and re-lock under the action of the cup holder spring.

[0045] The above is in conjunction with the appendix. Figures 6-10 A detailed description of the breast pump holder in this embodiment is provided. In addition, unless otherwise shown in the figures, the linkage 20 can also be constructed using a parallelogram mechanism. An angle locking mechanism can be installed at any pivot joint of the parallelogram mechanism. Two opposing links on the parallelogram mechanism can be mounted, one on the base 23 and the other on the cup holder 11.

[0046] To use the breast pump chair, the breastfeeding mother can sit on seat 94 and rock the control handle 991 forward or backward to adjust the angle of the main support frame 92 relative to the bottom support 93, raising or lowering the upper support frame 91, thereby adjusting the angle α between the forward-tilting backrest 95 and the horizontal plane to suit the breastfeeding mother's body shape. Place the breast pump in the cup holder 10 of the breast pump holder, and adjust the angle and left / right position of the ring seat 22a of the breast pump holder, the angle and position of the upper connecting rod 21 relative to the lower connecting rod 22, the angle, height, and depth of the cup holder 12, so that the horn cover of the breast pump in the cup holder 10 is facing the corresponding milk expression space 951, and the horn cover conforms to the breastfeeding mother's body shape. Adjust the height of the headrest 98 relative to the forward-tilting backrest 951, and lean the upper body forward against the forward-tilting backrest 95 to use the breast pump to express milk. During milk expression, the forward-leaning backrest 95 supports the upper body, allowing the breastfeeding mother to maintain a stable forward-leaning angle. This helps maintain negative pressure within the breast pump's nozzle, ensuring smooth milk flow and improving expression efficiency. It also effectively reduces the risk of lower back injury caused by prolonged forward leaning. The headrest 98 provides head support, effectively preventing lower back and head strain during expression. The breast pump holder provides support and lift, suitable for both electric and manual breast pumps. Unlike traditional manual breast pumps where one hand must hold the pump to ensure the nozzle fits against the areola, both hands can press the handles to generate stable suction, improving both efficiency and comfort. When expressing milk from one side, remove the breast pump holder ring 22a from one side's fixed crossbar 23a and insert it into the corresponding position on the other side's fixed crossbar 23a to express milk.
