In this document, "one" means not only "only one" but also a case of "more than one".
It should be further understood that the term "and/or" as used in this specification and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.
In this context, it is to be understood that, unless otherwise explicitly stated or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
In addition, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not intended to indicate or imply relative importance.
Generally, a conventional polishing head is of a substantially solid structure, and during a process of polishing a nail or a skin fiber tissue of a foot of a customer, the polishing head rotates at a high speed to generate friction with a polishing position of a human body, and the faster the rotation speed is, the longer the polishing time is, the higher heat generated by friction is, so that a certain degree of discomfort is caused to the customer, and the experience of the customer is poor. At present, the surface temperature of a polishing position is reduced by spraying cooling media such as water, alcohol or cooling liquid on the polishing position, however, the problem of friction and scalding cannot be solved completely from the root by the cooling mode, manual work is needed to be carried out continuously, once the operation is interrupted halfway, the temperature can be continuously raised, and manpower is greatly consumed. And the cooling medium is sprayed to the human body for a long time, so that the discomfort of customers is aggravated, and the actual experience of the customers is greatly influenced.
Based on the above recognition, the present invention provides in a first aspect a sanding tool 100 to address the problem of friction hair waving from a source. Specifically, as shown in fig. 1 to 11, the grinding tool 100 may specifically include a grinding head 110 and a clamping bar 120 mounted to the grinding head 110. The surface layer of the sanding head 110 forms a sanding surface 111. The polishing head 110 has a sealed cavity 112 therein. And the surface layer of the polishing head 110 is provided with a liquid injection hole 113 communicated with the cavity 112. The liquid injection hole 113 is used for high heat capacity liquid to enter the cavity 112 therethrough. And the liquid injection hole 113 is provided with a sealing member for sealing the cavity 112 when the high heat capacity liquid is completely filled in the cavity 112.
The grinding cutter 100 provided by the invention can automatically eliminate heat generated by friction between the grinding cutter and the surface 111 to be ground of a human body in the grinding process, can continuously cool the grinding position in the grinding process, does not need artificial auxiliary cooling, and improves the use experience of a user to a great extent and saves the labor cost.
Specifically, referring to fig. 1 to 5, the polishing head 110 may preferably be made of a metal material with good thermal conductivity and high hardness, such as tungsten steel, stainless steel, etc., without any limitation, so as to greatly improve the thermal conductivity and polishing performance, thereby effectively improving the service life and cooling effect.
Further, a cavity 112 is opened inside the polishing head 110, and the cavity 112 is filled with a high heat capacity liquid for cooling. Therefore, the side wall and the upper and lower end walls of the hollow polishing head 110 should be designed to be relatively light and thin, so that the cooling capacity of the high heat capacity liquid in the cooling state can be rapidly transmitted to the position to be polished of the human body through the side wall and the end walls of the polishing head 110, and the rapid and continuous cooling effect can be realized.
Of course, in this embodiment, the specific configuration of the polishing head 110 and the specific contour of the cavity 112 can be specifically set according to the actual use scenario and the actual application, and any structural changes are within the scope of the present disclosure and are not limited herein.
In this embodiment, the cavity 112 is always isolated from the outside in principle, so that the high heat capacity liquid filled in the cavity 112 can be recycled without causing volatilization of the components. Before the polishing head 110 is used, only the polishing head needs to be placed into refrigeration equipment, and high-heat-capacity liquid is cooled, so that the polishing head 110 can perform operation on the position to be polished of a human body and can perform rapid heat exchange with the position to be polished of the human body, heat generated due to friction can be automatically eliminated, the amount of the high-heat-capacity liquid stored in the cavity 112 is enough for icing treatment of the whole polishing process, artificial auxiliary cooling is not needed, and the use experience of a user is greatly improved, and the labor cost is saved. And the sanding head 110 can be put into use again by performing the cooling operation on the sanding head 110 again after each use of the sanding head 110 is finished. The structure greatly reduces the operation steps of replacing liquid by the polishing head 110, and effectively ensures that the polishing head 110 can provide enough cold quantity at the polishing position of a human body in the process of polishing at each time, so that the icing effect is better, and the use experience of customers is greatly improved.
Therefore, referring to fig. 4 and 5, in order to facilitate the rapid and smooth filling of the cavity 112 with the high heat capacity liquid, the surface layer of the polishing head 110 may be provided with a liquid injection hole 113 communicating with the cavity 112, and the cavity 112 may be filled with the high heat capacity liquid by inserting the needle tube of the syringe filled with the high heat capacity liquid into the liquid injection hole 113.
Further, in order to effectively and completely seal the high heat capacity liquid in the cavity 112, so that the high heat capacity liquid cannot overflow from the liquid injection hole 113 to the outside, the high heat capacity liquid can be effectively and completely sealed in the cavity 112 by filling the high temperature melted solder into the liquid injection hole 113 and forming a sealing member for sealing the liquid injection hole 113 after the high heat capacity liquid is cooled, and therefore the high heat capacity liquid can be completely sealed, and the high heat capacity liquid can be recycled without volatilization of components of the high heat capacity liquid. The solder can be soldering tin, and the liquid injection hole 113 can be sealed in a welding mode through an electric soldering iron. Compared with the method of directly blocking the liquid injection hole 113 by the sealing plug, the method has the advantages that the sealing effect is better by welding, and even if the polishing head 110 is under extreme conditions, high-heat-capacity liquid cannot leak. Of course, any other method for blocking the liquid injection hole 113 is also within the scope of the present patent, and will not be described in detail herein.
In this embodiment, the high heat capacity liquid is formed by mixing water and alcohol. The specific ratio of water and alcohol can be specifically adjusted according to the actual use requirements, such as the polishing time, the polishing area, and the like, without being limited too much.
It is worth mentioning that the freezing point of water is 0 deg.C and the freezing point of alcohol is-117.3 deg.C under standard atmospheric pressure. Therefore, the freezing point of the high heat capacity liquid formed by mixing the two is between the two, so that the polishing head 110 can keep a frozen state for a long time after being subjected to cooling treatment, and the polishing head 110 can rapidly cool the position to be polished of a human body in the process of operating the position to be polished.
More particularly, the specific heat capacity of water is 4.2 x 10^ 3J/(kg-), the specific heat capacity of alcohol is 2.4 x 10^ 3J/(kg-), the specific heat capacity of mixed liquid is between water and alcohol, the polishing head 110 can utilize the specific heat capacity of high heat capacity liquid to absorb a part of temperature in the polishing process, the temperature rise of polishing is slower, thereby the sharpness of the polishing surface 111 can be effectively ensured to be kept more permanent, the phenomenon of cutter adhesion can not easily occur, thereby the service life of the polishing head 110 can be greatly prolonged, and further, the cost is saved.
Certainly, from the aspect of the comfort level of polishing, the density of water at normal temperature is 1.0 x 10^3kg/(m ^3), the density of alcohol is 0.987 x 10^3kg/(m ^3), the density of the hard alloy used by the polishing head 110 is about 14.4 x 10^3kg/(m ^3), so through setting up the cavity 112 inside the polishing head 110, and the technical scheme of filling high heat capacity liquid can make the whole weight of the polishing head 110 compare with the traditional solid body structure, more light, more be favorable to the staff to carry out permanent operation, and effectively improve the comfort level of customers.
In this embodiment, referring to fig. 2 and 6, one end of the sanding head 110 is provided with a mounting portion 114 for docking with a clamping bar 120. Specifically, the mounting portion 114 may have a slot 1141 formed therein for receiving the end of the clamping rod 120, and the slot 1141 may be adapted to the end of the clamping rod 120. The slot 1141 is provided with a first exhaust hole 1142 communicating with the cavity 112, the first exhaust hole 1142 is used for exhausting the gas in the slot 1141 to the cavity 112 in the process of inserting the clamping rod 120 into the slot 1141, and the gas in the cavity 112 is exhausted to the outside through the liquid injection hole 113.
Specifically, in order to ensure that the clamping rod 120 does not easily fall off from the slot 1141 after being inserted into the slot 1141, thereby forming a stable joint with the polishing head 110, a layer of solder may be covered on the surface layer of the slot 1141, the solder is melted by heating the mounting portion 114 at a high temperature, and the clamping rod 120 is inserted into the slot 1141 when the solder is in a melted state, so that the end of the clamping rod 120 and the slot 1141 are firmly welded together by the solder, thereby forming a welded connection with the clamping rod 120. This type of welding may facilitate timely adjustment of concentricity between the sanding head 110 and the clamping bar 120 during the welding process.
Further, referring to fig. 6, the first venting hole 1142 communicating with the cavity 112 is disposed inside the slot 1141, and the opening of the first venting hole 1142 can effectively enable the clamping rod 120 to rapidly vent the welding gas generated in the slot 1141 to the cavity 112 in the process of inserting and embedding in the slot 1141, and the welding gas is discharged to the outside through the liquid injection hole 113. Therefore, the clamping rods 120 can be smoothly inserted into the slots 1141 without being blocked by welding gas, welding firmness is guaranteed to a great extent, and welding accuracy is greatly improved.
It should be noted that in this embodiment, the welding operation between the clamping rod 120 and the polishing head 110 is performed before the cavity 112 is not filled with the high heat capacity liquid, so as to facilitate smooth discharge of the welding gas formed inside the slot 1141, and the first vent holes 1142 can be blocked by the end of the clamping rod 120, so that the cavity 112 is always in a closed state. After the clamping bar 120 is welded to the polishing head 110, a filling operation of a high heat capacity liquid is performed.
It should be noted that, in this embodiment, after the clamping rod 120 and the polishing head 110 are welded, and before the polishing head 110 is ready to perform operation on the to-be-polished position of the human body, one end of the clamping rod 120, which is far away from the polishing head 110, may be mounted on the driving member, and the driving member drives the polishing head 110 to rotate, so that the polishing surface 111 performs cutting and polishing on the to-be-polished position. It is within the scope of the present disclosure that the driving member may be any member for driving the polishing head 110 to rotate, such as a polishing machine.
In this embodiment, referring to fig. 6 to 11, the mounting portion 114 may preferably be disposed on the central axis of the polishing head 110, so that the polishing head 110 can be rotated more smoothly without causing polarization.
Further, the mounting portion 114 may be recessed toward the cavity 112 or extend away from the cavity 112. The polishing head 110 can be specifically set according to the profile configuration of the polishing head 110, so that the practical application scene of the polishing head 110 can be greatly enriched.
Specifically, as a preferred example of the present embodiment, referring to fig. 1 to 6, the polishing head 110 may have a truncated cone shape, that is, the polishing head 110 has a tapered cylindrical structure, and when an included angle formed between an upper end surface and a side surface of the polishing head 110 is 95 degrees, it is beneficial for a worker to perform a polishing operation in an optimal hand posture without easily generating a fatigue feeling, from an ergonomic viewpoint. Wherein the taper design is beneficial to the trimming of the nail surface by a worker on the one hand and the grinding trimming of the nail length on the other hand.
Further, as the polishing head 110 is long, in order to effectively prevent the skin of a customer from being scratched by distractions or other misoperation of a worker during polishing, the joint of the upper end surface and the side surface of the polishing head 110 and the joint of the lower end surface and the side surface of the polishing head 110 can be rounded, so that the probability of accidents during polishing can be reduced to a great extent, and the potential safety hazard is reduced fundamentally. Of course, the fillet design is also favorable for trimming the rear edge part of the fingernail, and based on the characteristics of few contact points and no tip of the arc modeling, the operation difficulty can be greatly reduced, and the comfort level of a customer in the polishing process can be improved.
Further, in this example, the sanding head 110 may be a unitary structure with the cavity 112 being formed directly into the sanding head 110 during the manufacturing process. Based on different polishing types, for example, when working on nails and aged cuticles of skin, a cutting mode is usually adopted to remove hard fibrous tissues on the surface layer, and then a fine polishing mode is adopted to further refine and trim the polishing position. Therefore, the polishing surface 111 can flexibly change the polishing type according to the actual use requirement so as to meet various polishing forms.
For example, the polishing surface 111 may be a surface layer of the polishing head 110, which is directly subjected to a cross grooving process, so that the polishing surface 111 forms a cross-distributed blade-shaped structure, which may increase the smoothness of chip removal on one hand, and make the polishing sharper on the other hand, and meanwhile, the service life of the polishing head 110 may not be affected too much, which is more beneficial to cutting and polishing the skin fiber tissue.
Further, referring to fig. 3, the upper end surface of the polishing head 110 is designed to be a tooth-open surface which is excessively engaged with the side surface, so that the end portion can be used for cutting and polishing, and is more comfortable visually based on aesthetic principles without generating an excessively obtrusive feeling.
Further, in this example, referring to fig. 4 and 6, the mounting portion 114 may be preferably disposed to be concave toward the cavity 112, so as to not only reduce the overall weight of the polishing head 110, but also perfectly accommodate the mounting portion 114 inside the polishing head 110, thereby improving the overall aesthetic appearance.
It should be noted that, in the present example, referring to fig. 5, the liquid injection hole 113 is opened at an end of the polishing head 110 away from the mounting portion 114, and the liquid injection hole 113 is disposed in an inclined manner, so as to facilitate guiding the high heat capacity liquid into the cavity 112 quickly. Specifically, a certain amount of high heat capacity liquid can be extracted by a syringe, and then the needle tube of the syringe is inserted into the liquid injection hole 113 to fill the entire cavity 112 with the high heat capacity liquid. It should be noted that the diameter of the liquid injection hole 113 should be larger than the diameter of the needle tube, so that the gas in the cavity 112 can be discharged from the gap between the liquid injection hole 113 and the needle tube during the process of injecting the high heat capacity liquid into the cavity 112 by the needle tube, and the high heat capacity liquid can be effectively prevented from entering the cavity 112 quickly and smoothly due to the formation of vacuum inside the cavity 112.
Of course, as another preferred example of this embodiment, referring to fig. 9-11, the sanding head 110 may be cylindrical and of a split design. Specifically, the sanding head 110 may include a body 115 and a connector 116 mounted to the body 115, the body 115 and the connector 116 collectively forming the cavity 112. It should be noted that, in order to reduce the difficulty of the manufacturing process of the polishing head 110, the two components are assembled together after the body 115 and the joint 116 are manufactured and processed separately, and then the two components are welded into the integrated polishing head 110 by applying solder to the joint of the two components. That is, the polishing head 110 is still in the final state of a one-piece construction. Wherein, the accessible is used for the butt joint boss 1162 that is the convex form in the one end setting of body 115 at joint 116, inserts through the butt joint boss 1162 and inlays inside body 115, can improve the steadiness that body 115 and joint 116 docked, prevents that the phenomenon of separation from appearing after the permanent use of process in both.
Further, in this example, referring to fig. 10, the mounting portion 114 may be disposed at an end of the joint 116 away from the body 115 and extend away from the cavity 112 for abutting against the clamping rod 120, which may greatly improve the structural stability of the sanding head 110 during rotation.
Further, referring to fig. 11, the liquid injection hole 113 may be disposed at an end of the main body 115 away from the joint 116, and may be disposed obliquely, but is not limited thereto.
In the above two examples, referring to fig. 5 and 11, the end of the well 112 corresponding to the pour hole 113 is formed in a ridge shape extending convexly toward the pour hole 113, and the pour hole 113 is provided corresponding to an intermediate position of the ridge shape, so that the extended length of the pour hole 113 can be shortened to a large extent, and thus, the high heat capacity liquid can be made to enter the well 112 quickly and smoothly.
Of course, as another preferred example of this embodiment, referring to fig. 7 and 8, the sanding head 110 may be in the shape of a flat butterfly and be of a split design. Specifically, the sanding head 110 may include a body 115 and a connector 116 mounted to the body 115, the body 115 and the connector 116 collectively forming the cavity 112. It should be noted that the principle of the split design in the present example is the same as that in the above examples, both the principle and the principle are to reduce the difficulty in the production and processing of the polishing head 110, and finally, the two are welded into the polishing head 110 as a whole by means of welding.
The first limit step 1151 is circumferentially arranged on the circumferential side edge of the body 115 facing one end of the joint 116, correspondingly, the second limit step 1163 is circumferentially arranged on the circumferential side edge of the joint 116 for abutting one end of the body 115, when the joint 116 and the body 115 are abutted, the side ends of the first limit step 1151 and the second limit step 1163 are abutted and matched to form a complementary matching mode, and the joint 116 and the body 115 are prevented from moving transversely. Then weld joint 116 and body 115 in an organic whole, can improve the body 115 and the firm of joint 116 butt joint to a great extent, prevent the phenomenon that the two appear and separate after long-term use.
Further, in this example, referring to fig. 8, the mounting portion 114 may be disposed at an end of the joint 116 away from the body 115 and extend away from the cavity 112 for abutting against the clamping rod 120, which may greatly improve the structural stability of the sanding head 110 during rotation.
Furthermore, in this example, referring to FIG. 8, the liquid injection hole 113 is disposed at one end of the joint 116 facing the mounting portion 114, and a second vent hole 1161 communicating with the cavity 112 is further opened at a position of the joint 116 adjacent to the liquid injection hole 113. Since the pressure of the chamber 112 is increased when the high heat capacity liquid is injected into the chamber 112, when the pressure exceeds a certain range, the high heat capacity liquid cannot smoothly enter the chamber 112 due to the limitation of the pressure, and by additionally providing the second exhaust hole 1161, the pressure of the chamber 112 can be exhausted from the second exhaust hole 1161 during the injection, thereby facilitating the rapid injection of the high heat capacity liquid. The second vent hole 1161 is disposed adjacent to the injection hole 113, which is beneficial to the high heat capacity liquid to flow smoothly because the air pressure around the liquid is small during the flowing process.
It is worth mentioning that during the process of filling the high heat capacity liquid into the cavity 112, the polishing head 110 should be turned over so that the filling hole 113 and the second exhaust hole 1161 are disposed upward, so as to prevent the high heat capacity liquid from overflowing from the cavity 112.
It is more worth mentioning that, referring to fig. 8, the polishing surface 111 is formed on the surface layer of the body 115, and the polishing surface 111 can be in a slightly convex arc surface shape, so that the volume of the cavity 112 can be enlarged, the high heat capacity liquid can cover the whole area of the polishing surface 111 and improve the stability of the structure of the cavity 112, and the polishing surface can be adapted to the sole structure of a customer, conforms to the ergonomic design, and is more comfortable and efficient in the polishing process.
It should be noted that, referring to fig. 4, 8 and 10, the polishing surface 111 may be formed by a disposable polishing sand paper attached to the surface layer of the polishing head 110, and specifically, the sand paper may be a coarse-grinding sand paper or a fine-grinding sand paper, which is not limited herein. The abrasive paper has low cost, can be replaced in time, and is safe and sanitary. Most importantly, since the surface layer of the polishing head 110 is not directly used for polishing, the service life of the polishing head 110 is prolonged, and the production cost is reduced. Of course, the polishing surface 111 may also be formed by plating diamond particles on the surface of the polishing head 110, so that the polishing surface 111 is sharper during polishing and has high durability.
Of course, the specific configuration of the polishing surface 111 is not limited, and the polishing type can be flexibly changed according to the actual use requirement so as to meet the requirements of various polishing forms.
The invention also provides a method for manufacturing the grinding cutter 100 in the second aspect, which specifically comprises the following steps: the surface of the slot 1141 formed in the mounting portion 114 is covered with a layer of solder. The mounting portion 114 is heated at a high temperature to melt the solder, and the clamping rod 120 is inserted into the slot 1141 when the solder is in a molten state, so that the clamping rod 120 is welded to the mounting portion 114. The high heat capacity liquid is delivered to the chamber 112 through the injection hole 113 by a syringe. When the cavity 112 is completely filled with the high heat capacity liquid, the solder melted at high temperature is filled in the liquid injection hole 113, and the sealing member formed after the solder is cooled is used for sealing the cavity 112.
Meanwhile, the invention also provides a use method of the grinding tool 100 in a third aspect, which specifically comprises the following steps: the sanding head 110 is placed in a refrigeration device to cool the sanding head 110. Wherein the refrigeration equipment may include, for example, a refrigerator, an ice bank, etc., without limitation. Further, the sanding head 110 is removed from the refrigeration unit after a predetermined period of time has elapsed. Of course, if the sanding head 110 is not in use, it may be placed in the refrigeration equipment for a long period of time and removed again until needed. Further, the clamping rod 120 is installed on the driving member, and the polishing surface 111 is aligned to the position to be polished of the human body, and then the driving member operates to drive the polishing head 110 to rotate, so that the polishing surface 111 performs cutting and polishing on the position to be polished. Then, the above processes are circulated, so that the polishing head 110 can be used in a circulating and reciprocating manner, the material and production cost is greatly reduced, and the use experience of customers is greatly improved.
It should be noted that the above embodiments can be freely combined as necessary. The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and these modifications and improvements should also be considered as the protection scope of the present invention.
