Description

Technical Field

[0001] This invention belongs to the field of steam cleaning technology for nursing bottles, and specifically relates to a nursing bottle cleaning device. Background Technology

[0002] Nursing bottles, also known as baby bottles, are containers used to feed infants. They are usually made of glass, plastic, or stainless steel. In current technology, the bottle and nipple need to be cleaned after use to effectively prevent milk residue from causing bacterial growth. Current cleaning methods involve using a sponge brush to clean the inner wall of the bottle. This method only thoroughly cleans the inner wall and bottom, leaving the nipple, the inner wall of the straw, and the corners where the inner and bottom walls of the bottle are difficult to clean. This results in significant milk residue, which can spoil and breed bacteria over time, seriously affecting the health of the infants using these bottles. Furthermore, bottle cleaners are used to remove oils from the milk. These cleaners contain chemical reagents, and if not thoroughly cleaned, residue can remain. Prolonged use of such bottles is detrimental to the health of infants. Current technology also uses sponge-like structures to clean the nipples, but these devices lack integration when used separately. In postpartum care centers and neonatal wards, batch cleaning requires frequent equipment changes, making the process cumbersome. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a device that can thoroughly clean nursing bottles.

[0004] The technical solution adopted to solve the above technical problem is: a nursing bottle cleaning device, including a control lever for hand control, a bottom cleaning cover for cleaning the bottle wall is fixedly connected to one end of the control lever, and a secondary cleaning kit for cleaning the nipple and straw is provided at the end of the bottom cleaning cover away from the control lever.

[0005] The above technical solution allows the bottom cleaning cover to be stirred in the nursing bottle by hand using the control lever, thereby cleaning the inner wall of the nursing bottle. The inner wall of the nipple and the inner wall of the straw in the auxiliary cleaning kit can also be cleaned by hand using the control lever.

[0006] A steam inlet connector for introducing steam is fixedly connected through the upper surface of the bottom cleaning hood, and a steam exhaust structure is provided on the outside of the bottom cleaning hood.

[0007] Through the above technical solution, the steam inlet connector is connected to the pressure relief valve of the pressure cooker or the steam outlet of the steam generator via a hose, so that the steam inlet connector introduces high-temperature steam into the bottom cleaning hood and discharges it, which acts on the inner wall of the feeding bottle, the inner wall of the nipple and the inner wall of the straw to remove the grease left by the dairy products. This cleaning method does not require the intervention of chemical agents and effectively avoids residue.

[0008] Furthermore, the bottom cleaning cover includes a cleaning cover body fixedly connected to the control handle, a cleaning brush sleeve fixedly fitted on the outer side of the cleaning cover body, the cleaning brush sleeve being made of silicone material, the steam exhaust structure including a plurality of evenly distributed steam generating holes opened on the side walls of the cleaning cover body and the cleaning brush sleeve, and a support spring fixedly connected to the middle position of the inner top wall of the cleaning cover body.

[0009] Through the above technical solution, the main body of the cleaning cover, made of rigid plastic, can effectively support and fix the cleaning brush sleeve. The cleaning brush sleeve is made of soft silicone material, which can rub and clean the inner wall of the bottle without damaging it. The steam generator hole can discharge the hot steam inside the main body of the cleaning cover, which acts on the inner wall of the bottle to remove the grease. There is no need to use chemical cleaning agents, making it safer and healthier.

[0010] Furthermore, the auxiliary cleaning kit includes a rigid slider that is slidably connected through the bottom of the cleaning cover body. The rigid slider has a nipple-shaped structure. The end of the support spring away from the inner top wall of the cleaning cover body is fixedly connected to the upper surface of the rigid slider. A nipple brush sleeve is fitted and fixedly connected to the outer wall of the rigid slider. The nipple brush sleeve is made of silicone material.

[0011] Through the above technical solution, a silicone nipple brush sleeve is fixed on the outside of the rigid slider. The material is relatively soft. Under the action of the support spring, the rigid slider can be popped out and provided with auxiliary support. The rigid slider with a nipple-shaped structure is arc-shaped and has a pointed end, which can clean the corner of the bottom of the bottle and also clean the nipple, making the nipple cleaning more thorough. Under the action of squeezing force, the auxiliary cleaning set can be retracted into the bottom cleaning cover without affecting the cleaning of the bottom of the bottle.

[0012] Furthermore, a pressing control post is fixedly connected to the middle of the upper surface of the rigid slider. The pressing control post is hollow inside, and a groove with the same inner diameter as the pressing control post is opened inside the rigid slider. A hose cleaning plug is slidably connected to the bottom of the rigid slider. A pulling nylon line is slidably connected through the hose cleaning plug, and a pulling block is fixedly connected to the bottom of the pulling nylon line.

[0013] Through the above technical solution, the pressing control column can slide and limit the rigid slider, and assist in positioning the relative position of the rigid slider. The inside of the pressing control column is hollow, which facilitates the installation of the reset support spring and the pulling nylon line. The hose cleaning plug is made of sponge material and has good softness. When the hose cleaning plug is pulled out and inserted into the bottle hose, it can slide in the bottle hose to clean the bottle hose. The pulling block can control the pulling of the nylon line, thereby controlling the pulling of the hose cleaning plug.

[0014] Furthermore, a sliding tray is fixedly connected to the top of the pressing control column, the sliding tray is slidably connected to the inner wall of the control lever, a spring limiting mechanism is provided on the side wall of the sliding tray, and a limiting fixing plate is fixedly connected to the inner wall of the control lever below the sliding tray.

[0015] Through the above technical solution, the sliding tray and the limiting and fixing plate cooperate with each other to limit the secondary cleaning kit when it pops out, and the secondary cleaning kit is linked with the sliding tray by pressing the control column. The spring limiting mechanism fixes or releases the sliding tray, thereby fixing or releasing the secondary cleaning kit.

[0016] Furthermore, a reset support spring is fixedly connected to the groove position of the rigid slider, and a limit slider is fixedly connected to the middle position of the pull nylon line at the press control column. The outer diameter of the limit slider is smaller than the inner diameter of the reset support spring.

[0017] With the above technical solution, when the nylon line is pulled out, the reset support spring is compressed and stores energy. When the nylon line is released, it automatically resets. By setting a limit slider, the nylon line can pass through the hose after being pulled out a certain distance. Then, the nylon line is pulled further, causing the limit slider to move together with the hose cleaning plug on the inner wall of the hose, thus achieving the purpose of cleaning.

[0018] Furthermore, a top limiting slider is provided on the inner wall of the control lever at the upper position. The top limiting slider is slidably connected to the inner wall of the control lever, and the top of the pull nylon line and the top of the reset support spring are both fixedly connected to the lower surface of the top limiting slider.

[0019] Through the above technical solution, the top limit slider can fix the reset support spring and the pulling nylon line. When the nylon line is pulled, the reset support spring can be compressed simultaneously, so that the reset support spring can reset the pulling nylon line when it resets.

[0020] Furthermore, the spring limiting mechanism includes limiting grooves formed on the side wall of the sliding tray and the inner wall of the control lever. A spring pin is slidably connected to the inner wall of the limiting groove at the sliding tray position. A limiting spring is fixedly connected between the spring pin and the corresponding inner wall of the limiting groove. A control pressing post is slidably connected to the inner wall of the limiting groove at the control lever position. The end of the control pressing post away from the spring pin is slidably connected through the control lever. A pull-back spring is fixedly connected between the control pressing post and the corresponding inner wall of the limiting groove.

[0021] With the above technical solution, when the control pressing column is pressed, the spring pin is pressed into the limiting groove of the sliding tray. Under the action of the support spring, the auxiliary cleaning kit pops out. When the auxiliary cleaning kit is pressed into the bottom cleaning cover, the sliding tray slides upward. Under the action of the limiting fixing spring, the spring pin is pressed into the limiting groove of the control lever, thus fixing the sliding tray. Pulling back the spring resets the control pressing column when it is not pressed, thus preventing accidental pressing of the spring pin.

[0022] Furthermore, a protective soft film is attached and fixed to the outer wall of the control lever at the position where the control pressing column passes through.

[0023] Through the above technical solution, the protective membrane can form a protective layer at the position of the control button, making the use of the control button more comfortable and preventing steam leakage at the through hole from causing burns to the user.

[0024] The beneficial effects of the present invention are as follows: (1) The present invention sets a bottom cleaning cover and a secondary cleaning kit. The bottom cleaning cover can effectively and thoroughly clean the inner wall and bottom of the nursing bottle. The secondary cleaning kit can effectively and thoroughly clean the corners of the inner wall of the nursing bottle near the bottom, the nipple position of the nursing bottle, and the nursing bottle tubing. The cleaning is thorough and without dead corners. The integration is high and the operation is simple and convenient. (2) The present invention sets a steam inlet connector and a steam exhaust structure. When cleaning the nursing bottle, the connected steam generating mechanism can inject high-temperature steam into the bottom cleaning cover. The high-temperature steam is discharged from the steam generating hole of the steam exhaust structure and acts on the nursing bottle. It can clean the residual grease on the bottle wall and disinfect the nursing bottle. There is no need for the intervention of chemical cleaning agents. There is less residue and the cleaning is healthier. The steam can also disinfect the equipment body when it is in the bottom cleaning cover, avoid the growth of bacteria on the equipment body, and also avoid cross-infection between nursing bottles, making it safer to use.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0028] like Figure 1-8 As shown, a nursing bottle cleaning device of this embodiment includes a control lever 1 for hand-held control. One end of the control lever 1 is fixedly connected to a bottom cleaning cover 2 for cleaning the bottle wall. The bottom cleaning cover 2, away from the control lever 1, is provided with a secondary cleaning kit 3 for cleaning the nipple and straw. The bottom cleaning cover 2 can be stirred in the nursing bottle by holding the control lever 1, thereby cleaning the inner wall of the nursing bottle. The inner walls of the nipple and straw are rubbed and cleaned by holding the control lever 1.

[0029] The auxiliary cleaning kit 3 includes a rigid slider 30 that slides through and is slidably connected to the bottom of the cleaning cover body 21. The rigid slider 30 has a nipple-shaped structure. The end of the support spring 23 away from the inner top wall of the cleaning cover body 21 is fixedly connected to the upper surface of the rigid slider 30. A nipple brush sleeve 31 is fixedly connected to the outer wall of the rigid slider 30. The nipple brush sleeve 31 is made of silicone material. The silicone nipple brush sleeve 31 is fixedly fitted on the outside of the rigid slider 30. Its material is relatively soft. Under the action of the support spring 23, the rigid slider 30 can be popped out and provided with auxiliary support. The nipple-shaped rigid slider 30 is arc-shaped and has a pointed end, which can clean the corner of the bottom of the bottle and also clean the nipple, making the nipple cleaning more thorough. Under the action of squeezing force, the auxiliary cleaning kit 3 can be retracted into the bottom cleaning cover 2 without affecting the cleaning of the bottom of the bottle.

[0030] A pressing control post 24 is fixedly connected to the middle of the upper surface of the rigid slider 30. The pressing control post 24 is hollow inside, and a groove with the same inner diameter as the pressing control post 24 is opened inside the rigid slider 30. A hose cleaning plug 32 is slidably connected to the bottom of the rigid slider 30. A pull nylon line 28 is slidably connected through the hose cleaning plug 32, and a pull block 33 is fixedly connected to the bottom of the pull nylon line 28. The pressing control post 24 can limit the sliding of the rigid slider 30 and assist in positioning the relative position of the rigid slider 30. The hollow design of the pressing control post 24 facilitates the passage of the reset support spring 26 and the pull nylon line 28. The hose cleaning plug 32 is made of sponge material and has good softness. When the hose cleaning plug 32 is pulled out and inserted into the bottle hose, it can slide in the bottle hose to clean the bottle hose. The pull block 33 can control the pull of the nylon line 28, thereby controlling the pull of the hose cleaning plug 32.

[0031] A reset support spring 26 is fixedly connected to the groove position of the rigid slider 30. A limit slider 29 is fixedly connected to the middle position of the pull nylon line 28 at the press control post 24. The outer diameter of the limit slider 29 is smaller than the inner diameter of the reset support spring 26. When the nylon line 28 is pulled out, the reset support spring 26 is compressed and stores energy. When the pull nylon line 28 is released, the pull nylon line 28 is automatically reset. By setting the limit slider, the pull nylon line 28 can pass through the hose after being pulled out a certain distance. Then, if the pull nylon line 28 is pulled out again, the limit slider will drive the hose cleaning plug 32 to move together and move on the inner wall of the hose to achieve the purpose of cleaning.

[0032] The bottom cleaning cover 2 includes a cleaning cover body 21 fixedly connected to the control handle 1. A cleaning brush sleeve 20 is fixedly fitted on the outside of the cleaning cover body 21. The cleaning brush sleeve 20 is made of silicone. The steam exhaust structure includes several evenly distributed steam generating holes 22 on the side walls of the cleaning cover body 21 and the cleaning brush sleeve 20. A support spring 23 is fixedly connected to the middle of the inner top wall of the cleaning cover body 21. The cleaning cover body 21, as a rigid plastic material, can effectively support and fix the cleaning brush sleeve 20. The cleaning brush sleeve 20, made of soft silicone, can rub and clean the inner wall of the bottle without damaging it. The steam generating holes 22 can discharge the hot steam inside the cleaning cover body 21, which acts on the inner wall of the bottle, thus removing the grease from the inner wall of the bottle. This eliminates the need for chemical cleaning agents, making it safer and healthier.

[0033] A sliding tray 27 is fixedly connected to the top of the control column 24. The sliding tray 27 is slidably connected to the inner wall of the control lever 1. A spring limiting mechanism is provided on the side wall of the sliding tray 27. A limiting plate 25 is fixedly connected to the inner wall of the control lever 1 below the sliding tray 27. The sliding tray 27 and the limiting plate 25 cooperate with each other to limit the secondary cleaning kit 3 when it pops out. By pressing the control column 24, the secondary cleaning kit 3 is linked with the sliding tray 27. The spring limiting mechanism fixes or releases the sliding tray 27, thereby fixing or releasing the secondary cleaning kit 3.

[0034] The spring limiting mechanism includes limiting grooves 8 formed on the side wall of the sliding tray 27 and the inner wall of the control lever 1. A spring pin 10 is slidably connected to the inner wall of the limiting groove 8 at the position of the sliding tray 27. A limiting spring 9 is fixedly connected between the spring pin 10 and the corresponding inner wall of the limiting groove 8. A control pressing post 7 is slidably connected to the inner wall of the limiting groove 8 at the position of the control lever 1. The end of the control pressing post 7 away from the spring pin 10 is slidably connected through the control lever 1. The control pressing post 7 is fixedly connected to the corresponding inner wall of the limiting groove 8. With a pull-back spring 6, when the control pressing column 7 is pressed, the spring pin 10 is pressed into the limiting groove 8 of the sliding tray 27. Then, under the action of the support spring 23, the auxiliary cleaning kit 3 pops out. When the auxiliary cleaning kit 3 is pressed into the bottom cleaning cover 2, the sliding tray 27 slides upward. Under the action of the limiting fixing spring 9, the spring pin 10 is pressed into the limiting groove 8 of the control handle 1, thus fixing the sliding tray 27. The pull-back spring 6 makes the control pressing column 7 reset when it is not pressed, avoiding accidental pressing of the spring pin 10.

[0035] A protective soft film 5 is attached and fixed to the outer wall of the control handle 1 at the position where the control press column 7 passes through. The protective soft film 5 can form a protective layer at the position of the control press column 7, making the control press column 7 more comfortable to use and preventing steam from leaking at the through hole and causing burns to the user.

[0036] A steam inlet connector 4 for introducing steam is fixedly connected through the upper surface of the bottom cleaning cover 2. A steam exhaust structure is provided on the outside of the bottom cleaning cover 2. The steam inlet connector 4 is connected to the pressure relief valve of the pressure cooker or the steam outlet of the steam generator through a hose, so that the steam inlet connector 4 introduces high-temperature steam into the bottom cleaning cover 2 and then discharges it. It acts on the inner wall of the feeding bottle, the inner wall of the nipple and the inner wall of the straw to remove the oil left by the dairy products. This cleaning method does not require the intervention of chemical agents and effectively avoids residue.

[0037] A top limiting slider 210 is provided on the upper part of the inner wall of the control lever 1. The top limiting slider 210 is slidably connected to the inner wall of the control lever 1. The top of the pull nylon line 28 and the top of the reset support spring 26 are both fixedly connected to the lower surface of the top limiting slider 210. The top limiting slider 210 can fix the reset support spring 26 and the pull nylon line 28. When the pull nylon line 28 is pulled, the reset support spring 26 can be compressed simultaneously, so that when the reset support spring 26 resets, the pull nylon line 28 is reset.

[0038] The working principle of this embodiment is as follows: When using it, you need to wear heat-proof gloves in advance. Connect the steam generator or pressure cooker's steam outlet to the steam inlet connector 4 of this invention through a hose. Steam will be continuously introduced into the cleaning cover body 21 and discharged through the steam generating hole 22 for 15-20 seconds to make the temperature of the discharged steam stable.

[0039] After the steam temperature stabilizes, the staff rinses the feeding bottle with clean water. Holding the control lever 1, the staff inserts the bottom cleaning cover 2 into the feeding bottle. The cleaning brush sleeve 20 rubs against the inner wall of the feeding bottle to clean it. Tilt the control lever 1 so that the cleaning brush sleeve 20 contacts the bottom of the feeding bottle to clean it. By pressing the protective soft film 5, the control pressing column 7 squeezes the spring pin 10. The spring pin 10 is pressed into the limiting groove 8 of the sliding tray 27, causing the rigid slider 30 to pop out under the action of the support spring 23. The sliding tray 27 contacts the limiting fixing plate 25, and the rigid slider 30 is then assisted in fixing under the action of the support spring 23. The nipple brush sleeve 31 can then be used to clean the nipple and the corner of the bottom of the feeding bottle. During this cleaning process, the high-temperature steam nozzle effectively removes grease from the inner wall of the feeding bottle and assists in sterilizing the feeding bottle.

[0040] Pulling the pull block 33 causes the pull nylon line 28 to be pulled out. The pulled nylon line 28 passes through the breastfeeding bottle tubing to be cleaned. Continuing to pull the pull nylon line 28 causes the limiting slider 29 to contact the tubing cleaning plug 32 and drive the tubing cleaning plug 32 to slide inside the breastfeeding bottle tubing, thereby cleaning the tubing. The above cleaning method can thoroughly clean the inside of the breastfeeding bottle without any blind spots.

[0041] After cleaning, release the nylon rope 28. Under the action of the reset support spring 26, pull the nylon rope 28 and the hose cleaning plug 32 to spring back to their original position. Then press down on the auxiliary cleaning kit 3. Under the pressure, the support spring 23 is compressed, and the auxiliary cleaning kit 3 is pressed into the cleaning cover body 21. The sliding tray 27 will also slide upward, so that the spring pin 10 is re-inserted into the limiting groove 9 of the control lever 1, so that the sliding tray 27 and the auxiliary cleaning kit 3 are relatively fixed.

[0042] After completing the above operations, let the entire device stand still for 20-30 seconds, and then continue to sterilize and disinfect the device body with high-temperature steam to effectively avoid cross-infection between breastfeeding bottles.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
