Description

Technical Field

[0001] The invention relates to the technical field of silicone rubber material manufacturing, and in particular to a temperature-adjustable silicone massage head and a preparation process thereof. Background Art

[0002] Silicone massage heads are common massage tools with many advantages. Made of soft and flexible silicone, they are comfortable to the touch, can fit the curves of the human body well, simulate the feel of a professional masseur, and bring users a comfortable massage experience. Silicone massage heads also have a variety of massage functions and strength adjustment functions, which can promote blood circulation, effectively eliminate body fatigue, and relieve muscle tension and discomfort. In terms of durability and hygiene, silicone massage heads are not easy to deform or damage, are easy to clean, are not easy to hide dirt, and can maintain hygiene. In addition, silicone is odorless and non-toxic, has good chemical stability, and is suitable for people of all skin types.

[0003] Silicone massage heads are highly safe and will not cause skin allergies, and are suitable for people with all skin types. Some products, such as silicone massage heads for head massagers, also have dustproof, waterproof and shockproof properties, and can even be washed, and can be used wet or dry. However, existing silicone massage heads also have some disadvantages. In terms of heating function, most silicone massage heads cannot guarantee that the massage touch will not be affected while heating. Although some heating massage heads can achieve the heating function, Chinese patent CN211675298U, a full silicone vibration heating massager, includes: an inner shell, an outer shell and a movement; the inner shell is a hollow structure, the outer shell is arranged on the outer periphery of the inner shell, the outer shell completely wraps the inner shell, and the outer shell is made of silicone, the movement is arranged inside the inner shell, the movement includes a motor, a first eccentric shaft and a second eccentric shaft connected to the output shafts on both sides of the motor, a battery, a circuit board and a control panel, the motor is fixed in the inner shell, the motor and the circuit board are connected to the battery, and the motor and the control panel are connected to the circuit board. However, the patented heating plate is arranged on the outer surface of the inner shell and located on the inner surface of the outer shell. The heating plate is connected to the circuit board. However, due to the addition of the heating element or the problem of the heating method, the softness, elasticity, etc. of the massage head are changed, which affects the comfort during massage and cannot achieve the ideal massage effect.

[0004] During use, the silicone massage head is easy to stick to clothes. This is mainly because the surface characteristics of the silicone material make it easy to produce static adsorption when it comes into contact with clothes. Especially in a dry environment, this adsorption phenomenon is more obvious, which brings inconvenience to the user. The existing static elimination methods mainly include static eliminators, such as Chinese patent CN220307437U, but installing a static eliminator alone will increase the size of the silicone massage head; adding specific antistatic agents and other additives, such as Chinese patent CN107779052A, may increase costs and affect the physical properties of silicone products. Summary of the invention

[0005] To this end, the present invention provides a temperature-adjustable silica gel massage head and a preparation process thereof to solve the above-mentioned problems.

[0006] In order to achieve the above object, the present invention provides the following technical solutions:

[0007] According to one aspect of the present invention, a method for preparing a temperature-adjustable silicone massage head is provided, the method comprising:

[0008] Step 1, preparing silicone liquid, stirring the prepared silicone liquid evenly, evacuating the mixture, pouring the mixture into the inner layer mold and letting it stand, and heating and drying the inner layer mold after standing to obtain the inner layer silicone;

[0009] Step 2: sew the heating wire and the thermocouple to the surface of the inner silicone layer by needle and thread. After the sew is completed, connect the heating wire and the thermocouple to the DuPont wire by soldering to obtain a heated inner silicone layer.

[0010] Step 3, placing the heated inner layer silicone obtained in step 2 into the outer layer mold, and adding the silicone liquid prepared in step 1;

[0011] Step 4, heating and drying the outer layer mold to obtain massage head silica gel;

[0012] Step 5: Install the massage head silicone into the massage head bracket and wrap it with nylon mesh to obtain a temperature-adjustable silicone massage head.

[0013] The silicone massage head is made of PS6600 series silicone;

[0014] Furthermore, in step 1, the silicone liquid includes glue A and glue B. As an example, preferably, glue A: glue B = 0.9-1.1, more preferably glue A: glue B = 1:1.

[0015] Further, the A glue includes: vinyl silicone oil, methyl silicone oil and white carbon black; the B glue includes: hydrogenated silicone oil and platinum catalyst. As an example, in the preferred A glue, the vinyl silicone oil can account for 60%-80% of the total mass of the A glue. It is the main polymer component and provides the basic structure and elasticity of the silicone; the methyl silicone oil accounts for 10%-30% of the total mass of the A glue, and its main function is to adjust the flexibility and lubricity of the silicone; the white carbon black accounts for 5%-20% of the total mass of the A glue. White carbon black is mainly used to enhance the strength, hardness and thixotropy of the silicone, so that the silicone has better physical properties. In the preferred B glue, the hydrogenated silicone oil generally accounts for 50%-90% of the total mass of the B glue. It acts as a crosslinking agent and undergoes a crosslinking reaction with the vinyl silicone oil in the A glue, which plays a key role in the curing and molding of the silicone; the platinum catalyst accounts for 10%-50% of the total mass of the B glue in the B glue. It is mainly used to accelerate the crosslinking reaction between the hydrogenated silicone oil and the vinyl silicone oil, so that the silicone can be cured within a suitable time, and can ensure a good curing effect.

[0016] Furthermore, in the step 1, the vacuuming time is 3-5 minutes.

[0017] Furthermore, in the step 1, the standing time is 1-3 minutes.

[0018] Silicone liquid configuration parameters:

[0019] Stirring time: The stirring time of silicone liquid is generally 5-20 minutes to ensure that all ingredients are fully mixed. This is because if the stirring is not sufficient, glue A and glue B and other additives may not be completely evenly dispersed, which will affect the performance of silicone, such as uneven hardness after curing.

[0020] Vacuuming time and pressure: The vacuuming time is usually 3-5 minutes, and the vacuum degree can reach -0.08-0.1MPa. Vacuuming is to remove bubbles in the silicone liquid to prevent cavities from appearing inside the silicone after molding, which will affect the appearance and performance.

[0021] Standing time (inner silicone): The standing time is about 1-3 minutes, allowing the silicone liquid to initially stabilize in the mold to avoid deformation and other problems during the subsequent heating and drying process.

[0022] Inner mold heating and drying temperature and time: The heating temperature is generally 40-50℃, and the heating time is 2-4 hours. This temperature and time range can fully cure the silicone. Too high a temperature may cause cracks on the silicone surface, and too low a temperature will result in incomplete curing.

[0023] Furthermore, in step 2, the heating wire and thermocouple suturing parameters are as follows: needle and thread specifications: the heating wire is used as the thread, and is directly sutured on the silicone with a needle, and the wire diameter is about 0.1-0.2mm. The needle is a round-head needle with a diameter of 0.1-0.2mm, which can avoid damaging the inner layer of silicone, the heating wire, and the thermocouple during the suturing process. The thickness and diameter of the heating wire and the thermocouple are respectively: the heating wire is 0.15-0.2mm and the thermocouple is 1.5mm.

[0024] In the step 4, the outer layer mold is heated and dried, the heating and drying conditions are 40-50° C., and the heating time is 2-4 hours.

[0025] In step 5, the parameters of the massage head silicone bracket and the wrapped nylon mesh are: This step is mainly a mechanical assembly process. When installing the massage head bracket, it is necessary to ensure that the massage head silicone fits tightly with the bracket, which is generally fixed by a slot or glue. When wrapping the nylon mesh, the mesh count of the nylon mesh can be 40-50 to ensure good touch and breathability.

[0026] Furthermore, the silicone massage head mold includes an upper mold, a concave mold, an inner lower mold and an outer lower mold from top to bottom; wherein the upper mold is also provided with a guide groove and an overflow groove; and the concave mold is provided with a wire groove.

[0027] The layered mold structure of the present invention: This multi-layer mold structure from top to bottom (upper mold, concave mold, inner layer lower mold and outer layer lower mold) helps to accurately control the molding of different parts of the silicone massage head. The inner layer lower mold can be used to mold the inner layer structure of the massage head first, and the outer layer lower mold is used to wrap the outer layer of silicone, so that the massage head forms an inner and outer layer structure with different functions. In this way, components such as heating wires and thermocouples can be easily placed inside, while ensuring the integrity and aesthetics of the outer layer of silicone.

[0028] The upper mold guide slot and overflow slot: The guide slot can guide the silicone liquid to flow accurately into each part of the mold, ensuring that the silicone fills the mold evenly and avoiding partial insufficient filling. The overflow slot can discharge excess silicone liquid when too much silicone liquid is injected, preventing the mold from being damaged due to excessive pressure. At the same time, it can also ensure the dimensional accuracy of the massage head, because after the excess silicone is discharged, the final size of the massage head is more in line with the design requirements.

[0029] Concave mold wire slot: The advantage of setting wire slots in the concave mold is that it can provide accurate wiring channels for heating wires and thermocouples. During the molding process, these lines can be neatly placed in the wire slots to avoid the lines being randomly distributed in the silicone. This not only facilitates subsequent assembly steps (such as connecting DuPont wires through needle and thread sewing and soldering), but also prevents the lines from being damaged by the extrusion of silicone, ensuring the reliability of the heating and temperature detection functions.

[0030] According to another aspect of the present invention, there is provided a temperature-adjustable silicone massage head, which is prepared by any of the above-mentioned preparation methods.

[0031] Furthermore, the silicone of the massage head is divided into two layers, the inner layer of silicone is used to sew the heating wire and the thermocouple, and a secondary mold is performed on the inner layer of silicone to form an outer layer of silicone, ultimately forming a silicone massage head with adjustable temperature.

[0032] Furthermore, the silica gel component includes vinyl silicone oil, hydrogen silicone oil, methyl silicone oil, platinum catalyst, and white carbon black.

[0033] The present invention has the following advantages:

[0034] The present invention can integrate heating and temperature monitoring functions well inside the massage head by sewing the heating wire and the thermocouple in the inner layer of silicone. The heating wire can quickly and effectively adjust the temperature of the massage head, and the thermocouple can accurately measure the temperature, thereby achieving precise control of the temperature of the massage head and meeting the user's needs for different temperatures.

[0035] The inner layer of silica gel of the present invention serves as a protective layer for the heating wire and the thermocouple, and can prevent these components from being directly exposed to the external environment and being damaged. The present invention can avoid damage to the heating and temperature measuring components due to external force extrusion, friction or liquid immersion during use, thereby extending the service life of the components and improving the overall reliability of the massage head.

[0036] The presence of the inner and outer layers of silicone in the present invention can make the heat more evenly distributed on the surface of the massage head. The heat generated by the heating wire in the inner layer of silicone will be transferred to the outer layer through the inner layer, and the outer layer of silicone plays a certain buffering and heat-distributing role, avoiding local overheating and providing users with a more comfortable massage experience.

[0037] The present invention adopts an inner and outer two-layer silicone structure, which can enhance the overall toughness of the massage head compared to a single-layer silicone. The outer layer of silicone can withstand more external friction, extrusion and other mechanical forces, reducing the damage to the inner functional layer. This double-layer structure makes the massage head more durable and reduces the risk of functional failure due to external damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] Comparative Example 1

[0086] This comparative example provides a preparation process of a silicone massage head with non-adjustable temperature:

[0087] The difference between this comparative example and Example 1 is that this comparative example does not have step five and step six, that is, there is no heating device, and the rest is completely consistent with Example 1.

[0088] Comparative Example 2

[0089] This comparative example provides a preparation process of a temperature-adjustable silicone massage head:

[0090] An iron-chromium-aluminum alloy heating wire is used, and the rest is completely the same as in Example 1.

[0091] Comparative Example 3

[0092] This comparative example provides a preparation process of a temperature-adjustable silicone massage head:

[0093] An extremely fine thermocouple with a response speed of 500ms and a wire diameter of 0.1mm is used to control the temperature. Other parts are exactly the same as in Example 1.

[0094] Comparative Example 4

[0095] This comparative example provides a preparation process of a temperature-adjustable silicone massage head:

[0096] In this comparative example, the nylon mesh in step 10 is replaced with cotton cloth, and the rest is exactly the same as in Example 1.

[0097] Experimental Example 1

[0098] The silicone massage heads prepared in Examples 1-3 and Comparative Examples 1-4 were evaluated for experience, and the evaluation results are shown in Table 1.

[0099] Table 1

[0100] Hardness (shore) Heating speed(s) Tensile strength(Mpa) Example 1 5.2 40 6.5 Example 2 5 42 6.4 Example 3 6 41 6.7 Comparative Example 1 5.2 / 6.5 Comparative Example 2 5.3 48 6.5 Comparative Example 3 5.3 39 6.4 Comparative Example 4 5.3 41 6.5

[0101] Note: Heating rate refers to the time required for the massage head to heat to 55°C at a constant voltage.

[0102] Example 1: The hardness of the product is close to that of human skin; there are no obvious cavities or bubbles inside or outside the silicone; the thermocouple can accurately feedback temperature changes; there are no obvious traces of the heating wire on the surface and the heating effect is good; the nylon mesh can effectively prevent clothes from sticking.

[0103] Example 2: The hardness of the product is not significantly different from that of Example 1; there are tiny cavities and bubbles inside and outside the silicone; the thermocouple can accurately feedback temperature changes; the heating wire is not obviously exposed and the heating effect is good; the nylon mesh can effectively prevent clothes from sticking.

[0104] Example 3: The hardness of the product is not significantly different from that of Example 1; there are tiny cavities and bubbles inside and outside the silicone; the thermocouple can accurately feedback temperature changes; the heating wire is less flexible and difficult to sew, the heating wire has obvious traces of the circuit and the heating effect is average, the larger wire diameter results in smaller resistance, and it is difficult to meet the heating requirements; the nylon mesh can effectively prevent clothes from sticking.

[0105] Comparative Example 1: The performance of the silicone is not significantly different from that of Example 1, but it lacks a heating function and the massage experience is poor.

[0106] Comparative Example 2: The iron-chromium-aluminum alloy heating wire has a certain brittleness when heated for a long time, and there is a risk of the heating wire breaking when the massage head is used.

[0107] Comparative Example 3: The response speed of the ultra-fine thermocouple is faster than that of Example 1, but the cost is higher, and the thinner wire diameter may cause the temperature probe to break.

[0108] Comparative Example 4: Cotton cloth cannot effectively reduce friction for some clothing (such as denim, wool fabric and corduroy, etc.), and will pull the clothing during massage, causing discomfort to the user; at the same time, compared with nylon mesh, it is not aesthetically pleasing.

[0109] It can be seen that the present invention places the heating module inside the silica gel, which can ensure the heating effect without affecting the massage touch, and the surface of the massage head is wrapped with nylon mesh to prevent the massage head from sticking to clothes.

[0110] The silicone massage head of the present invention is not prone to serious discoloration and deformation during its preparation process, is not prone to generating bubble cavities, has a good heating effect and does not affect the massage effect. The silicone massage head of the present invention is wrapped with nylon mesh, and the user does not need to take off clothes during massage, and the silicone massage head will not stick to clothes and cause discomfort during massage.

[0111] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
