Description

Technical Field

[0001] The present invention belongs to the technical field of fur care device design, and in particular relates to a low-temperature plasma care device for hairy skin. Background Art

[0002] While pet hair provides a protective barrier for the skin, it also attracts a large amount of dirt and bacteria. Compared to the pH of human skin (approximately 5.5), the pH of pet skin is more neutral (pH 7.5), and its hair is also very suitable for the growth of microorganisms. Pets are prone to skin diseases with a high recurrence rate. If not treated promptly, they can easily produce odors, even foul odors. Pets are more sensitive to odors than humans, and pets have an animal instinct to lick their fur. If deworming and sterilization methods are used improperly or with drugs, they can easily cause pets to resist and endanger their health. Therefore, pet deworming, sterilization and deodorization technology must not only be efficient but also safe.

[0003] Low-temperature plasma generators are widely used in sterilization, deodorization and dust reduction due to their small size, low cost and low ozone release. In addition, the negative ions carried by low-temperature plasma have the effects of improving blood circulation, promoting metabolism and enhancing the body's immunity. Based on the aforementioned advantages of low-temperature plasma, it is applied to corresponding devices to achieve more efficient disinfection and sterilization of pets' fur and remove odors. For example, patent application number 202220122740.2 discloses a plasma pet care comb, which is equipped with a plasma tube and a corresponding fan to generate plasma clusters. The generated plasma clusters are blown out through the edge of the comb teeth under the action of the fan, thereby achieving the contact between the plasma clusters and the pet's fur to achieve the purpose of disinfection, sterilization and odor removal. However, for pets with abundant hair, the plasma clusters in this technical solution cannot contact the skin under the pet's hair or only have a small amount of contact, and its care effect on the pet's skin is limited; for example, patent application number 202111402 Patent No. 788.5 discloses a plasma sterilization pet comb, which is equipped with a plasma generating module to achieve the purpose of sterilizing and disinfecting pet fur through the plasma generated by it. However, the first component of the plasma generating module in the pet comb is arranged on the combing surface to generate plasma when the second component contacts it, and then achieves its sterilization and disinfection purpose through this part of the plasma. For pets with thick hair, the pet comb in this technical solution cannot have plasma contact with the skin under the pet's hair or only has a small amount of contact, and its care effect on the pet's skin is relatively limited. Summary of the Invention

[0004] Therefore, the present invention provides a low-temperature plasma care device for hair-covered skin, which can solve the technical problem in the prior art that the plasma generated in the low-temperature plasma care device for hair-covered skin cannot contact the skin under the hair over a large area, resulting in its relatively limited care effect on the skin.

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0041] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the outline of each component itself.

[0042] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used herein to describe the spatial positional relationship of a device or feature to other devices or features as shown in the figures. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figures. For example, if the device in the drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0043] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0044] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, a low-temperature plasma care device for hairy skin is provided, comprising:

[0045] The mounting carrier 1 includes a loading portion 11 , wherein the loading portion 11 has a first component assembly cavity 111 ;

[0046] A low-temperature plasma generating module (not labeled in the figure) is assembled in the first component assembly cavity 111. The low-temperature plasma generating module is capable of generating plasma. As this module is a relatively mature plasma generating technology in the industry, the present invention does not intend to protect the low-temperature plasma generating module, and a detailed description thereof will not be given here. However, it should be understood that the present invention uses a low-temperature plasma generating module to prevent potential hazards such as burns caused by the high temperature of the plasma on the object being acted upon.

[0047] A tube body 3, wherein a first end of the tube body 3 is assembled on the first end plate 12 of the mounting carrier 1, a second end of the tube body 3 is capable of contacting the skin beneath the hair, and the tube body 3 has a drainage channel 31 extending from the first end toward the second end. That is, the tube body 3 is a hollow cylindrical structure. In a preferred embodiment, the second end of the tube body 3 is semi-spherical.

[0048] The fan 4 is assembled in the first component assembly cavity 111 and is used to drive the generated plasma (clusters) at least partially into the drainage channel 31 through the first end and send it out through the second end.

[0049] In this technical solution, the plasma generated in the first component assembly cavity 111 is driven into the drainage channel 31 respectively provided in each tube body 3 by the fan 4 installed in the first component assembly cavity 111, and is drained to the skin covered by the hair, so that the plasma can directly contact the skin under the hair, thereby effectively eliminating the situation in which the plasma generated in the plasma care device in the prior art is largely blocked by the hair, resulting in a large amount of plasma not being able to directly contact the skin under the hair. The plasma can directly act on the skin and the roots of the hair, thereby improving the care effect of the plasma on the skin under the hair.

[0050] It should be noted that it is well known in the industry that plasma, especially low-temperature plasma, can form a protective layer at the location where it acts, which can surround the bacteria, viruses, odor molecules carried by the target, and mites on the pets, thereby decomposing the aforementioned substances or causing the corresponding substances to lose their activity, thereby achieving a high efficiency improvement in the sterilization, disinfection, deodorization and even mite removal effects; in addition, since the plasma in the present invention can be smoothly drained to the skin and the roots of the hair, it can also improve hair loss and has the effect of promoting wound healing and inhibiting the growth of bacteria and viruses.

[0051] The plasma generated by the low-temperature plasma care device for hairy skin of the present invention is non-toxic, odorless, green and environmentally friendly, and adopts a purely physical care (prevention and treatment) method. Compared with drug methods, it has the characteristics of low cost, safety, no side effects, and no drug resistance.

[0052] In some embodiments, the first end plate 12 is configured with a plurality of first through-holes (not labeled in the figure), and the plurality of tubes 3 are fixedly connected to each of the first through-holes. The aforementioned fixed connection is specifically a detachable fixed connection, for example, each tube 3 can be threadedly connected to the first through-hole, while a more preferred implementation method is an interference fit connection between the tube 3 and each first through-hole. In this technical solution, each tube 3 can be detachably fixedly connected to each of the first through-holes. If a portion of the tube 3 is damaged, it can be replaced individually, reducing the cost of the device.

[0053] In some embodiments, see Figure 1 As shown, the first end plate 12 is also constructed with a plurality of second through holes 121, and each of the first through holes and the second through holes 121 is spaced apart. After such arrangement, a portion of the plasma generated by the low-temperature plasma module can be guided to the skin and the hair roots through the aforementioned tubes 3, and the other portion can be blown onto the hair through the second through holes 121, thereby achieving the purpose of plasma all-round care from the hair roots to the hair tips, further improving the plasma care effect. The aforementioned first through holes and second through holes 121 can be specifically as follows Figure 1 The shown ones are arranged in a rectangular array to ensure uniformity of plasma action.

[0054] As a preferred embodiment, the aforementioned second through hole 121 and the first through hole are both circular holes, which are more convenient to process. The aperture of the second through hole 121 should be smaller than the flow diameter of the aforementioned drainage channel 31 to ensure that the plasma can be drained to the fur and hair roots to a greater extent. The aperture size of the aforementioned second through hole 121 can be reasonably selected based on the length of the drainage channel 31 and the size of the flow diameter.

[0055] See Figure 4 As shown, in a specific embodiment, the low-temperature plasma generating module includes a plasma power supply 21 and a plasma carbon electrode 22. The plasma power supply 21 is used to supply power to the plasma carbon electrode 22 to generate plasma. It can be understood that when the plasma power supply 21 supplies power to the plasma carbon electrode 22, the tip of the plasma carbon electrode 22 will generate a high-voltage corona, thereby ionizing the air flow passing through it into plasma. A PCB board 5 is also provided in the first component assembly cavity 111. The plasma carbon electrode 22 is assembled on the PCB board 5 (also known as a printed circuit board). The PCB board 5 is provided on a side surface facing the first end plate 12. The PCB board 5 has a first printed circuit (not labeled in the figure). The plasma power supply 21 is electrically connected to the plasma carbon electrode 22 via the first printed circuit. The PCB board 5 is constructed with a plurality of third through holes 51 extending through both sides thereof. The fan 4 is located on a side of the PCB board 5 facing away from the first end plate 12. The aperture of each of the third through holes 51 should be as large as possible while meeting the circuit layout requirements within the PCB board 5 to ensure that the flow resistance of the airflow driven by the fan 4 is as small as possible.

[0056] In this technical solution, by using the PCB 5 as both a mounting and fixing carrier for the plasma carbon electrode 22 and also as a carrier for routing the power cable for the plasma carbon electrode 22, i.e., the aforementioned first printed circuit, the difficulty of assembling and fixing components within the first component assembly cavity 111 is reduced. Furthermore, the provision of the third through hole 51 ensures smooth flow of air driven by the fan 4. It should be understood that the third through hole 51 should be positioned so as not to interfere with the printed circuits within the PCB 5.

[0057] Continue to see Figure 4As shown, an ultrasonic generating module (not labeled in the figure) is also assembled in the first component assembly cavity 111, and the ultrasonic generating module includes an ultrasonic generating disk 61 and an ultrasonic circuit board 62. The PCB board 5 also has a second printed circuit (not labeled in the figure), and the ultrasonic generating disk 61 is connected to the side surface of the PCB board 5 facing the first end plate 12, and the ultrasonic circuit board 62 is electrically connected to the ultrasonic generating disk 61 via the second printed circuit. The aforementioned ultrasonic generating module can be specifically a variable frequency ultrasonic generator, which can drive away various parasitic mites in the hair in various frequency bands (21KHz~45KHz). Specifically, relevant ultrasonic generators on the market can be used. The present invention does not improve its specific structure, but is only a selection and application of existing mature components. In this technical solution, by further arranging an ultrasonic generating module in the first component assembly cavity 111, ultrasonic waves can be used to drive away various parasitic mites in the hair. The mites are driven away to achieve multi-effect mite removal and further improve the care effect; and / or, an infrared LED module 63 is also assembled in the first component assembly cavity 111. The aforementioned infrared LED module 63 can specifically adopt a mature red light generator on the market. When the care device of the present invention is used to comb hair, such as combing pet hair, during the combing process, the red light with a wavelength of 650nm emitted through the aforementioned third through hole 51 can improve the pet's skin environment, thereby improving the pet's hair removal. The PCB board 5 also has a third printed circuit (not marked in the figure). The infrared LED module 63 is connected to the side surface of the PCB board 5 facing the first end plate 12, and the device power supply 64 is connected to the infrared LED module 63 via the third printed circuit. It can be understood that the aforementioned device power supply 64 serves as a power supply component for each electrical component in the entire device, and it is electrically connected to the corresponding components through corresponding circuits (circuits).

[0058] In this technical solution, the PCB board 5 serves as the installation carrier of the aforementioned plasma carbon electrode 22, ultrasonic generating disk 61 and infrared LED module 63. At the same time, various printed circuits are printed therein to realize the respective electrical connections between the corresponding power supply or circuit board and other components. This can greatly reduce the difficulty of setting up each component, making the component arrangement in the first component assembly cavity 111 more compact and reasonable.

[0059] In some embodiments, the fan 4 includes a hub (not labeled in the figure) and a plurality of blades (not labeled in the figure) connected to the outer circumferential wall of the hub. The projection area formed by the hub along its rotational axis on the PCB 5 is a first area, and the ultrasonic generator disk 61 is assembled within the first area, thereby reducing the obstruction of the ultrasonic generator disk 61 to the driving airflow. Furthermore, the infrared LED module 63 includes a plurality of infrared generators, each of which is spaced apart and arranged at an outer circumferential edge of the PCB 5. It should be noted that, at least when each infrared generator is in operation, the aforementioned second through holes 121 should be maintained unobstructed.

[0060] In an embodiment not shown in the figures, the PCB board 5 divides the first component assembly chamber 111 into an upper chamber and a lower chamber, the fan 4 is located in the upper chamber, and the plasma carbon electrode 22 is located in the lower chamber. In this technical solution, the PCB board 5 further serves as a partition component to divide the first component assembly chamber 111 into an upper chamber and a lower chamber, with the fan 4 located in the upper chamber and the plasma carbon electrode 22 located in the lower chamber. This ensures that the airflow driven by the fan 4 can flow completely toward the side of the target after being ionized to form plasma (through the second through hole 121 and the drainage channel 31), thus eliminating the possibility of the plasma airflow flowing back to the upper chamber, thereby further enhancing the effect of the plasma.

[0061] In a specific embodiment, the aforementioned low-temperature plasma care device may be, for example, a hair care cover, wherein the second end of each tube 3 of the hair care cover is passed through the user's hair and contacts the user's scalp.

[0062] In another specific embodiment, the low-temperature plasma care device is a care comb. In this case, the aforementioned tube body 3 is also the comb teeth. The mounting carrier 1 also includes a handheld portion 13 connected to the loading portion 11. A second component assembly cavity 131 is formed in the handheld portion 13. The second component assembly cavity 131 is assembled with at least one of a device power supply 64, an air quality detection component 65 (preferably arranged on the side of the plasma action position facing the care object), and a device main control board 66. In this way, by providing the handheld portion 13, it is convenient for the user to hold the device, thereby facilitating the user to comb hair (such as pet hair). In a specific embodiment, the aforementioned first component assembly cavity 111 and the second component assembly cavity 131 can be connected to form a cavity. Of course, according to actual needs, the aforementioned two assembly cavities can also be relatively independent cavities. It can be understood that the connecting cables between the components assembled in the two cavities should form an internal connection with each other.

[0063] In some embodiments, at least one of a device power switch 67, a display screen 68 (assembled on the side of the handheld portion 13 facing the user so that the user can visually observe the displayed content at any time), a charging interface 69, and a power indicator light 691 is assembled on the outer wall of the handheld portion 13, wherein the device power switch 67 is used to control the on and off of the device power supply 64, the display screen 68 is used to display the detection results of the air quality detection component 65, and the charging interface 69 is used to be electrically connected to an external power supply component to charge the device power supply 64.

[0064] The aforementioned air quality detection component 65 can specifically adopt a commercially available TVOC air quality detector, which detects the surrounding organic matter concentration and feeds back a signal to the device main control board 66. The device main control board 66 sends a corresponding organic matter concentration signal to the aforementioned display screen 68 after receiving the signal port feedback from the air quality detection component 65 to display the real-time concentration of organic matter thereon, so that the user can choose whether to perform further necessary care operations based on the display of the display screen 68.

[0065] The aforementioned device power supply 64 (specifically a storage battery) is electrically connected to the aforementioned device main control board 66 through wires, and the aforementioned device main control board 66 is electrically connected to the fan 4, plasma generating module, ultrasonic generating module, infrared LED module 63, device power switch 67, display screen 68, air quality detection component 65, charging interface 69, power indicator light 691 and PCB board 5 through corresponding wires.

[0066] The battery indicator 691 displays the remaining power of the device power supply 64. When the remaining power is low, the user can charge the device power supply 64 through the charging port 69, which can be a Type-C charging port, for example. The device power switch 67 allows the user to turn the entire device on or off.

[0067] In some embodiments, the fan 4 is a bidirectional axial flow fan, see Figure 2 Direction, that is, the fan 4 can drive the airflow to flow from top to bottom, and can also drive the airflow to flow from bottom to top. An air outlet is formed on the side of the loading part 11 opposite to the first end plate 12, and an airflow filter 14 is detachably connected to the air outlet. The aforementioned airflow filter 14 can specifically be a filter screen, which can filter out debris (hair, dust, and mite corpses, etc.) in the airflow flowing through it.

[0068] In this technical solution, by adopting a bidirectional axial flow fan, the driving direction of the airflow can be controlled to meet the different application needs of users. For example, when the bidirectional axial fan drives the airflow toward the nursing position (i.e. Figure 4When the orientation shown is from top to bottom), the low-temperature plasma generating module can be controlled to run to guide the generated plasma to the skin, hair roots and hair ends of the care object to achieve the plasma care purpose, and when the bidirectional axial fan rotates in the opposite direction to drive the airflow away from the care position (that is, Figure 4 When the orientation shown is from bottom to top, the debris attached to the skin and hair can be reversely adsorbed and separated. It can be understood that the flow aperture of the drainage channel 31 should be as large as possible at this time to ensure the smooth passage of related debris.

[0069] As a preferred embodiment, when the bidirectional axial flow fan can rotate in the opposite direction to achieve the purpose of reverse adsorption and separation of debris, a baffle (not shown in the figure) can also be provided on the first end plate 12. By changing the position of the baffle, the second through holes 121 on the first end plate 12 are blocked, thereby increasing the debris adsorption capacity at the second end of each tube body 3, thereby ensuring the debris adsorption and separation effect. The baffle is provided with a fourth through hole having a position and size corresponding to each second through hole 121. The baffle has a blocking position for blocking the second through hole 121 and a flow position for ensuring the flow through the second through hole 121. It can be slidably connected (for example, a sliding guide structure in which a track and a slider are engaged) to the outer surface of the first end plate 12. When the fan 4 rotates forward, that is, the airflow flows from top to bottom, the baffle is driven (for example, manually pushing the baffle) to be in the flow position, thereby ensuring that the plasma airflow can flow out in all directions to achieve the purpose of care, or when ultrasonic and infrared care are applied separately, the baffle is driven (for example, manually pushing the baffle) to be in the flow position. When the fan 4 rotates reversely, that is, the airflow flows from bottom to top, the baffle is driven to be in the blocking position, thereby ensuring a better effect of adsorption and separation of debris. It can be understood that the area on the baffle where the fourth through hole is not provided is the solid plate area. When there is an intersection between the fourth through hole and the second through hole 121, air flow is achieved. The best situation is that the second through hole 121 is completely covered by the fourth through hole. When there is no intersection between the fourth through hole and the second through hole 121, that is, when the aforementioned solid plate area completely covers the second through hole 121, blocking is achieved and the baffle is in the blocking position.

[0070] On the basis of the application condition that the fan 4 can rotate in the opposite direction to absorb and separate impurities, as a more preferred embodiment, a silicone diaphragm (not shown in the figure) is provided on the side of the aforementioned air flow filter 14 facing the fan 4, and a plurality of cross slits (i.e., cross-shaped slits) are formed on the aforementioned silicone diaphragm. When the fan 4 rotates forward, the airflow flows toward the side of the fan 4 through the airflow filter 14. Under the action of the airflow, the cross slits are deflected and opened toward the side of the fan 4. After the filtered airflow passes through the fan 4 and the third through hole 51 in turn, it is ionized by the plasma carbon electrode 22 at the lower side of the PCB board 5 to form plasma, and further flows out through the second through hole 121 and the drainage channel 31. When the fan 4 rotates in the opposite direction, the airflow enters the lower cavity through the drainage channel 31 and the second through hole 121 and further passes through the fan 4 through the third through hole 51 to flow toward the airflow filter 14. During the process, under the action of the airflow, the cross slit is deflected and opened toward one side of the airflow filter 14, and the airflow mixed with debris is filtered at the airflow filter 14 and the debris adheres to the inner side of the airflow filter 14 (that is, the side facing the silicone diaphragm). After the debris is adsorbed and separated, it is retained on the airflow filter 14. When the fan 4 stops rotating, due to the lack of airflow pressure, the cross slit of the silicone diaphragm returns to its initial planar state. At this time, some debris attached to the inner side of the airflow filter 14 may fall to the side of the silicone diaphragm facing the airflow filter 14 under the action of its own weight, and will not continue to fall downward, thus achieving temporary storage of the separated debris. Since the silicone diaphragm is arranged on the airflow filter 14 and the airflow filter 14 is detachable, after the debris adsorption and separation operation is completed, the user can remove the airflow filter 14 from the air outlet for necessary cleaning. It is worth emphasizing that, as a better embodiment, when the airflow flows from bottom to top, it is best to control the change of the baffle position to block the second through holes 121 on the first end plate 12, thereby increasing the debris adsorption capacity at the second end of each tube body 3 and ensuring the debris adsorption and separation effect.

[0071] In another preferred embodiment, a guide cover (not shown in the figure) is provided between the airflow filter 14 and the airflow inlet and outlet of the fan 4 toward the airflow filter 14 to ensure smooth flow of forward and reverse airflows.

[0072] It is easy for those skilled in the art to understand that, under the premise of no conflict, the advantageous technical features of the above-mentioned methods can be freely combined and superimposed.
