Description

Technical Field

[0001] This utility model relates to the field of beauty and hair care product technology, and more specifically to a nutrient solution exporting structure and a hair care comb. Background Technology

[0002] Currently, most beauty products on the market use liquid reservoirs to apply nutrient solution to the hair through the openings of the liquid guide needles. When using them, you need to press the comb teeth firmly against the scalp so that the liquid can be dispensed through the openings of the liquid guide needles. However, the shape of the human head is irregular, and the nutrient solution inevitably tilts from side to side with the liquid reservoir during use. The liquid dispensing volume of each liquid guide needle is uneven, resulting in uneven application, low utilization rate of the nutrient solution, and a poor user experience.

[0003] To overcome this problem, some products have improved the nutrient solution outlet structure. For example, Chinese Patent No. CN218073892U discloses a nutrient solution outlet structure, including a liquid box and guide teeth. The guide teeth are connected to the liquid box, and a first spring and a ball bearing are installed in the outlet channel of the guide teeth. The first spring provides force for the ball bearing to seal the outlet of the guide teeth. The liquid box is equipped with a guide component for nutrient solution flow, which is distributed along the arrangement direction of the guide teeth. The nutrient solution in the storage chamber is guided evenly into the outlet channel of the guide teeth through the guide component. Although this prior art can make the liquid output of the guide teeth more uniform, it uses more components and has a complex structure assembly. Utility Model Content

[0011] In a preferred embodiment, a liquid outlet is provided in the center of the bottom surface of the liquid storage box, and a sealing membrane is provided on the liquid outlet to seal the nutrient solution in the liquid storage box before assembly to prevent leakage.

[0012] In a preferred embodiment, the bottom surface of the mounting groove is provided with an upward-pointing spike-like structure in the middle, which corresponds to the position of the liquid outlet and is used to pierce the sealing membrane on the liquid outlet to allow the nutrient solution to flow out; the middle of the liquid guide plate is provided with a through hole for the spike-like structure to pass through, and the spike-like structure passes through the liquid guide plate to play a fixing role.

[0013] In a preferred embodiment, the edge of the liquid outlet is provided with a downward-facing annular protrusion so that the nutrient solution flows out more concentratedly. There is a gap between the bottom surface of the annular protrusion and the liquid guide plate to accommodate the nutrient solution, and when not in use, the nutrient solution can be evenly distributed on the liquid guide plate.

[0014] In a preferred embodiment, the top edge of the liquid storage box has a circumferential protrusion, and the liquid storage box overlaps the top surface of the mounting groove wall through the protrusion, so that the liquid storage box is suspended in the upper part of the mounting groove.

Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0028] Reference Figure 1-4 This invention describes a nutrient solution exporting structure and a hair comb according to an embodiment of the present invention.

[0029] In one embodiment, such as Figure 1-4 As shown, a nutrient solution export structure includes a storage box 3, a comb-tooth outer cover 4, and a guide needle 5. The storage box 3 is assembled on the comb-tooth outer cover 4. The bottom of the comb-tooth outer cover 4 is provided with at least one outlet hole 41, which is connected to the outlet channel inside the guide needle 5.

[0030] A flexible liquid guide plate 6 is provided below the liquid storage box 3. The liquid guide plate 6 has at least one cut 61, and each cut 61 is provided above each liquid outlet hole 41. The liquid storage box 3 is connected to a pressurizing component, which is used to apply air pressure to the liquid storage box 3 so that each cut 61 opens downward to communicate with the corresponding liquid outlet hole 41.

[0031] The comb-shaped outer cover 4 has comb teeth and liquid guiding needles 5 at its bottom. The liquid guiding needles 5 are located in the middle. There can be multiple comb teeth, which are distributed around the liquid guiding needles 5 at the bottom of the comb-shaped outer cover 4. The liquid storage box 3 is used to hold nutrient solution and has a liquid outlet 32 ​​at its bottom. The liquid guiding plate 6 is located below the liquid outlet 32 ​​and is installed on the comb-shaped outer cover 4. When there is no air pressure, the cut 61 is in a closed state, while under air pressure, the cut 61 opens downward. In actual application scenarios, the cut 61 can be a long strip cut or other shapes. The number of cuts 61 is the same as the number of liquid outlet holes 41, and there can be one or more, such as 4, 6, 8 or more. There is no limitation on the number and shape of the cuts 61.

[0032] In specific implementation, a sealing membrane can be provided at the liquid outlet 32, and a spike-like structure 42 is provided on the comb tooth cover 4. When the liquid storage box 3 is assembled on the comb tooth cover 4, the spike-like structure 42 punctures the sealing membrane of the liquid storage box 3, so that the nutrient solution flows out from the liquid outlet 32 ​​into the gap between the bottom of the liquid storage box 3 and the liquid guide plate 6.

[0033] This embodiment provides a nutrient solution outlet structure. By adding a flexible guide plate 6 above the outlet hole 41, it acts as a gate for the nutrient solution. First, when not in use, it ensures that the nutrient solution does not flow out of the incision 61, preventing the nutrient solution from flowing directly into the guide needle 5 and avoiding waste caused by accidental contact. Second, when not in use, the nutrient solution will flow evenly above the flat guide plate 6, achieving uniform distribution. Finally, when the device is turned on, the air pressure of the pressurizing component allows nutrient solution to flow out from each guide needle 5, improving the utilization rate of the nutrient solution and the user experience.

[0034] In this embodiment, the pressurization assembly includes an air pump hose 1, an air inlet cap 2, and an air pump 7. The air pump 7 is connected to the air inlet cap 2 through the air pump hose 1. The air inlet cap 2 is fastened to the air inlet 31 on the top of the liquid storage box 3. The structure is simple and easy to assemble and maintain.

[0035] The two ends of the air pump hose 1 are connected to the air pump 7 and the air inlet cap 2 respectively, and the air inlet cap 2 is detachably connected to the air inlet 31 of the liquid storage box 3.

[0036] In practice, in addition to air intake, the air inlet 31 can also be used to replenish the liquid in the liquid storage box 3. That is, when the nutrient solution is insufficient, the air inlet end cap 2 can be removed to add new nutrient solution to the liquid storage box 3.

[0037] In this embodiment, the nutrient solution outlet structure is located on the hair comb, and the air pump 7 is installed inside the handle of the hair comb, which can make full use of the internal space of the handle and effectively reduce the size of the comb.

[0038] The air pump 7 is located inside the handle and connected to one end of the air pump hose 1. The other end of the air pump hose 1 is located inside the comb head of the hair care comb and connected to the air inlet cap 2.

[0039] In practice, the handle is equipped with a control circuit board and a rechargeable battery. The handle surface is equipped with a switch button. The rechargeable battery is used to power the control circuit board and the air pump 7. The control circuit board is connected to the switch button and the air pump 7 respectively. When the user presses the switch button, the air pump 7 works and pressurizes the liquid storage box 3 through the air pump hose 1.

[0040] In this embodiment, the comb tooth cover 4 is provided with an installation groove for assembling the liquid storage box 3, the liquid guide plate 6 is provided at the bottom of the installation groove, and the bottom surface of the installation groove is provided with a liquid outlet hole 41.

[0041] The mounting groove is used to assemble and accommodate the liquid storage box 3. The liquid guide plate 6 can be laid flat at the bottom of the mounting groove, and each of its cuts 61 is set to correspond one-to-one with the liquid outlet 41 below.

[0042] In practice, the liquid guide needle 5 has a liquid outlet channel inside and a liquid outlet at the end. After the liquid storage box 3 is placed in the installation groove, the nutrient solution flows from the liquid storage box 3 into the gap between it and the liquid guide plate 6. When the air pump 7 of the pressurization component works, the cut 61 opens downward, and the nutrient solution enters the liquid outlet hole 41 through the cut 61, then flows into the liquid outlet channel inside the liquid guide needle 5 through the liquid outlet hole 41, and finally flows out from the liquid outlet at the end of the liquid guide needle 5.

[0043] Furthermore, the bottom of the mounting groove can be provided with at least two drainage holes 41 to increase the amount of nutrient solution output during combing and to make the output more uniform.

[0044] The comb-tooth outer cover 4 is provided with an installation groove for assembling the liquid storage box 3. The liquid guide plate 6 can be placed at the bottom of the installation groove. The structure is simple and the assembly is convenient.

[0045] In this embodiment, a liquid outlet 32 ​​is provided in the middle of the bottom surface of the liquid storage box 3, and a sealing membrane is provided on the liquid outlet 32, which can seal the nutrient solution in the liquid storage box 3 before assembly to prevent leakage.

[0046] Before the liquid storage box 3 is assembled onto the comb tooth cover 4, the sealing film can seal the nutrient solution inside the liquid storage box 3 to prevent leakage; moreover, the liquid outlet 32 ​​is located in the middle of the bottom surface of the liquid storage box 3, so that the distance from the liquid outlet 21 to the two sides of the mounting groove is the same, which facilitates the uniform flow of nutrient solution.

[0047] In this embodiment, the bottom surface of the mounting groove is provided with an upward-pointing spike-like structure 42 in the middle, which corresponds to the position of the liquid outlet 32 ​​and is used to pierce the sealing film on the liquid outlet 32 ​​to allow the nutrient solution to flow out; the middle part of the liquid guide plate 6 is provided with a through hole for the spike-like structure 42 to pass through, and the spike-like structure 42 passes through the liquid guide plate 6 to play a fixing role.

[0048] The number of spike-like structures 42 can be one, two or more, preferably two; specifically, when the liquid storage box 3 is assembled on the comb tooth cover 4, the spike-like structures 42 of the comb tooth cover 4 will extend into the liquid outlet 32 ​​and puncture the sealing membrane, so that the nutrient solution flows out from the liquid outlet 32.

[0049] In this embodiment, the edge of the liquid outlet 32 ​​is provided with a downward-facing annular protrusion so that the nutrient solution flows out more concentratedly. There is a gap between the bottom surface of the annular protrusion and the liquid guide plate 6 to accommodate the nutrient solution, and when not in use, the nutrient solution can be evenly distributed on the liquid guide plate 6.

[0050] In this embodiment, the top edge of the liquid storage box 3 is provided with a circumferential protrusion. The liquid storage box 3 is connected to the top surface of the mounting groove wall through the protrusion, so that the liquid storage box 3 is suspended in the upper part of the mounting groove. The structure is simple and the installation is convenient.

[0051] In this embodiment, the liquid guiding sheet 6 is made of silicone, which has good softness and corrosion resistance, and is environmentally friendly and non-toxic, making it safer to use.

[0052] Based on the above embodiments, the working principle of the nutrient solution export structure is as follows: when the liquid storage box 3 is assembled on the comb tooth cover 4, the middle spike-like structure 42 of the comb tooth cover 4 pierces the sealing film of the liquid storage box 3.

[0053] When a user uses the hair comb, from an ergonomic perspective, the hair comb will swing back and forth and side to side to comb the hair, and the nutrient solution will also flow back and forth and side to side, staying above the liquid guide plate 6. Because the liquid guide plate 6 has one or more slits 61, the nutrient solution is sealed above the liquid guide plate 6 when the hair comb is not turned on.

[0054] After the machine is turned on, as the air pump 7 is turned on, the air pump hose 1 inputs air pressure to the air inlet end cap 2 and then to the liquid storage box 3. At this time, under the influence of the air pressure inside the liquid storage box 3, the cut 61 on the liquid guide plate 6 opens downward. At this time, the nutrient solution remaining above the liquid guide plate 6 will flow out evenly to the liquid guide needle 5.

[0055] The aforementioned nutrient solution outlet structure is achieved through the principle of air pressure. A gate is designed before the nutrient solution flows to the guide needle 5, and a guide plate 6 allows the nutrient solution to remain before the guide needle 5. Firstly, this provides excellent storage for the nutrient solution. When the hairbrush is not in use, the nutrient solution is perfectly preserved above the guide plate 6, ensuring a uniform amount of nutrient solution above each guide needle 5. Secondly, when the hairbrush is in use, the nutrient solution has already flowed from the reservoir 3 above the guide plate 6. It is then subjected to air pressure transmitted from the air pump 7 to the reservoir 3. Under this pressure, each slit 61 on the guide plate 6 opens due to downward tension, allowing the nutrient solution to flow evenly downwards through each slit 61 to the outlet channel of each guide needle 5, ensuring a uniform flow of nutrient solution from each guide needle 5. When the nutrient solution is insufficient, removing the air inlet cap 2 allows for the addition of new nutrient solution to the reservoir 3.

[0056] In another embodiment, the present invention provides a hair care comb that includes a nutrient solution exporting structure as described in any of the above embodiments, which can significantly improve the utilization rate of nutrient solution and enhance the user experience through a simple structure.
