A massager with a novel heating structure

Abstract

This utility model discloses a massager with a novel heating structure, relating to the field of massager technology. It includes: a first housing; a massage head; a support component; a heating element; and a heat-conducting component. The heating element is powered by an external power source or a battery built into the massager. The heat from the heating element is transferred to the massage head through the heat-conducting component, thus heating the massage head. Simultaneously, the massage head generates heat through friction with the heat-conducting component during rotation, further enhancing the heating effect. The overall structure is simple, and replacement costs are low when the heating element is damaged. It also avoids the electrical sparks that can occur with carbon brush heating systems due to long-term friction between the carbon brush and the metal contact surface. Furthermore, it prevents oxidation and loosening of the contact points after carbon brush wear, which could lead to unstable current conduction or even leakage.

Description

Technical Field

[0001] This utility model relates to the field of massager technology, and in particular to a massager with a novel heating structure. Background Technology

[0002] With increasing life pressures and growing physical fatigue, people need to use assistive tools to relieve fatigue. With the widespread application of mechanization and automation, various massagers that simulate manual massage have entered thousands of households, and massage devices have thus emerged.

[0003] To meet people's needs, existing massagers usually have a heating function. For example, a heated massage pillow with announcement number CN209075395U has a heating lamp plate installed on the massage head. It is electrically connected through a double-ring contact plate and carbon brush assembly to ensure that the heating lamp plate has a continuous power supply when it rotates with the massage head. This achieves the effect of adding a heating function to the three-dimensional kneading massage function, further promoting blood circulation throughout the body, accelerating metabolism, and further enhancing the effects of disease prevention, health care and strengthening the body, bringing people a better experience.

[0004] However, the existing method of achieving smooth circuit heating through carbon brush assemblies has a relatively complex structure. Long-term friction between the carbon brush and the metal contact surface can generate electric sparks, which may ignite the plastic parts or fabric inside the massager, especially in humid environments or when the circuit is aging, posing a fire risk. After the carbon brush wears out, the contact points may oxidize and loosen, leading to unstable current conduction or even leakage. The carbon brush must be replaced regularly after it wears out, otherwise it will cause heating failure or increase safety risks. Replacing the carbon brush requires professional disassembly of the massager (rotary structures are usually quite complex), which not only increases the user's time cost, but also accumulates the cost of spare parts (carbon brush + labor) in the long run. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, this utility model provides a massager with a novel heating structure to solve the problems of the existing carbon brush assembly having a complex structure, generating electric sparks due to long-term friction, and not only posing a risk of leakage after wear, but also having high replacement costs.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a massager with a novel heating structure, comprising:

[0007] First casing;

[0008] A massage head, which is rotatably positioned above the first housing;

[0009] The support member is fixed to the top surface of the first housing;

[0010] A heating element, which is fixed to the top surface of the support member;

[0011] A heat-conducting component is fixed to a support or a heating component, and the bottom and top surfaces of the heat-conducting component are in contact with the heating component and the bottom surface of the massage head, respectively.

[0012] Preferably, a rotary drive mechanism is provided inside the first housing. The rotary drive mechanism includes a first motor, a first worm, a first worm wheel, two sets of reduction gears, a rotating wheel, and a rotating rod. The rotating wheel is fixed to the outer surface of the rotating rod. The rotating rod, the first worm wheel, and the two sets of reduction gears are all rotatably disposed inside the first housing. One end of the rotating rod passes through the top surface of the first housing and is fixedly mounted with a massage head. The output end of the first motor is fixedly mounted with the first worm. The first worm has first worm wheels symmetrically meshed on both sides of the first worm. Each first worm wheel is connected to the rotating wheel through a set of reduction gears.

[0013] Preferably, each reduction gear set includes a first reduction gear, a second reduction gear, and a third reduction gear. The first reduction gear and the first worm gear rotate coaxially, and the second reduction gear and the third reduction gear rotate coaxially within the first housing. The diameter of the first reduction gear is smaller than that of the second reduction gear, and the diameter of the third reduction gear is smaller than that of the rotating wheel and the second reduction gear. The first worm gear, the third reduction gear, and the rotating wheel are arranged in an arc shape.

[0014] Preferably, it also includes a second housing, which has a lifting mechanism for driving the lifting and lowering movement of the first housing.

[0015] Preferably, the lifting mechanism includes a second motor, a second worm, a second worm wheel, a double-acting lead screw, a slider, and a top rod. The output end of the second motor is fixedly mounted with the second worm, which meshes with the second worm wheel. The second worm wheel is fixed to one end of the double-acting lead screw. The double-acting lead screw is rotatably disposed within the second housing. Two sliders are symmetrically helically screwed onto the outer surface of the double-acting lead screw. Each slider has a top rod hinged to both ends. One end of the top rod is hinged to the first housing.

[0016] Preferably, one side wall of the first housing is arc-shaped, and one end of each of the two top rods is hinged to both ends of the arc-shaped side wall of the first housing.

[0017] Preferably, it also includes a number of limiting members disposed in the second housing, wherein each pair of opposite top rods is in contact with the limiting member on the side away from each other.

[0018] Preferably, it also includes a lumbar support plate, on which a sliding groove is formed, and racks are symmetrically installed on both sides of the inner wall of the sliding groove. The second housing is provided with a walking drive mechanism and a walking gear, the walking drive mechanism is connected to the walking gear, and the walking gear meshes with the rack.

[0019] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0020] This invention uses an external power source or the built-in battery of the massager to power the heating element. The heat from the heating element is transferred to the massage head through a heat-conducting component, thereby heating the massage head. At the same time, the massage head generates heat due to friction with the heat-conducting component during rotation, further improving the heating effect. The overall structure is simple, and the replacement cost is low when the heating element is damaged. It also avoids the electric sparks that may occur when the carbon brush assembly heating method is used due to long-term friction between the carbon brush and the metal contact surface. It also avoids the oxidation and loosening of the contact points after the carbon brush wears out, which may lead to unstable current conduction or even leakage. Attached Figure Description

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model is further described below in conjunction with specific embodiments. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0029] like Figures 2-5 As shown, this utility model provides a massager with a novel heating structure, including: a first housing 1, a massage head 2, a support 3, a heating element 4, and a heat-conducting element 5;

[0030] The massage head 2 is rotated and positioned above the first housing 1;

[0031] Support 3 is fixed to the top surface of the first housing 1;

[0032] Heating element 4 (which can be a heating plate) is fixed to the top surface of support element 3;

[0033] The heat-conducting component 5 (which can be a metal heat-conducting sheet) is fixed on the support component 3 or the heating component 4, and the bottom and top surfaces of the heat-conducting component 5 are in contact with the heating component 4 and the bottom surface of the massage head 2, respectively.

[0034] When the massage head 2 needs to be heated, the heating element 4 is powered on by an external power source or the battery built into the massager (the specific power supply for the heating element 4 is existing technology and will not be described in detail here). The heat from the heating element 4 is transferred to the massage head 2 through the heat conductor 5, thereby heating the massage head 2. At the same time, the massage head 2 will also generate some heat due to friction with the heat conductor 5 during rotation, further improving the heating effect. The overall structure is simple, and the replacement cost is low when the heating element 4 is damaged. It also avoids the situation where the carbon brush and the metal contact surface may generate electric sparks due to long-term friction in the carbon brush assembly heating method. It also avoids the situation where the contact point may oxidize or loosen after the carbon brush wears, resulting in unstable current conduction or even leakage.

[0035] Since the heating element 4 is fixed above the first housing 1 by the support 3, its position remains unchanged. This avoids damage to the wires that may be caused by the heating element 4 rotating and getting tangled with the connecting wires between it and the external power supply or battery, thus avoiding the risk of electric leakage.

[0036] like Figure 2 , Figure 4 and Figure 5As shown, a rotary drive mechanism 6 is provided inside the first housing 1. The rotary drive mechanism 6 includes a first motor 601, a first worm gear 602, a first worm wheel 603, two sets of reduction gears, a rotating wheel 607, and a rotating rod 608. The rotating wheel 607 is fixed to the outer surface of the rotating rod 608. The rotating rod 608, the first worm wheel 603, and the two sets of reduction gears are all rotatably disposed inside the first housing 1. One end of the rotating rod 608 passes through the top surface of the first housing 1 and a massage head 2 is fixedly installed. The output end of the first motor 601 is fixedly installed with the first worm gear 602. The first worm gear 602 is symmetrically meshed with the first worm wheel 603 on both sides. Each first worm wheel 603 is connected to the rotating wheel 607 through a set of reduction gears.

[0037] In use, the first motor 601 is started, which drives the first worm gear 602 to rotate. The first worm gear 602 drives the two first worm wheels 603 to rotate. Each first worm wheel 603 drives a rotating wheel 607 to rotate through a reduction gear set. The rotating wheel 607 drives the rotating rod 608 to rotate, thereby driving the massage head 2 to rotate, realizing the rotational massage function and further improving the massage effect.

[0038] Specifically, the first housing 1 includes a detachably connected upper housing 102 and a lower housing 101, which facilitates the assembly of the first motor 601, the first worm gear 602, the first worm wheel 603, two sets of reduction gear sets, the rotating wheel 607 and the rotating rod 608.

[0039] like Figure 4 and Figure 5 As shown, each reduction gear set includes a first reduction gear 604, a second reduction gear 605, and a third reduction gear 606. The first reduction gear 604 and the first worm gear 603 rotate coaxially, and the second reduction gear 605 and the third reduction gear 606 rotate coaxially within the first housing 1. The diameter of the first reduction gear 604 is smaller than the diameter of the second reduction gear 605, and the diameter of the third reduction gear 606 is smaller than the diameter of the rotating wheel 607 and the second reduction gear 605. The first worm gear 603, the third reduction gear 606, and the rotating wheel 607 are arranged in an arc shape.

[0040] The first worm gear 603 (first reduction gear 604), the third reduction gear 606, and the rotating wheel 607 are arranged in an arc shape. The arc arrangement makes the power transmission path more in line with the circular motion characteristics in mechanical principles. During power transmission, the meshing points of the reduction gears are distributed on the arc path, which can distribute the torque more evenly. Compared with the straight arrangement, the arc arrangement can reduce the impact and vibration caused by sudden changes in force during the meshing of the reduction gears. In multi-stage arc reduction gear transmission, the power can be transmitted more smoothly from the first reduction gear 604 to the rotating wheel 607, reducing the deformation and wear of each reduction gear, reducing noise, and improving the efficiency and accuracy of transmission. In the arc arrangement, the axial force directions of adjacent reduction gears are partially canceled out due to the angle difference, and the total axial force is significantly reduced, which can extend the service life of the reduction gears. The arc arrangement disperses the error through the arc, and the positional deviations of adjacent reduction gears are mutually constrained, reducing the risk of resonance. The advantages are more obvious when there are a large number of reduction gears.

[0041] By using the arc-shaped arrangement of the first worm gear 603 (first reduction gear 604), the third reduction gear 606, and the rotating wheel 607, the overall length of the equipment is significantly shortened compared to the linear arrangement of the same number of reduction gears. This greatly reduces the excess space left in other parts of the equipment, resulting in a more compact internal structure and a higher degree of space miniaturization optimization.

[0042] like Figure 2 and Figure 6 As shown, it also includes a second housing 7, and the second housing 7 is provided with a lifting mechanism 8 for driving the lifting and lowering movement of the first housing 1;

[0043] Specifically, the lifting mechanism 8 includes a second motor 81, a second worm 82, a second worm wheel 83, a double-acting screw 84, a slider 85, and a top rod 86. The output end of the second motor 81 is fixedly mounted with the second worm 82, which meshes with the second worm wheel 83. The second worm wheel 83 is fixed to one end of the double-acting screw 84. The double-acting screw 84 is rotatably mounted inside the second housing 7. Two sliders 85 are symmetrically spirally screwed onto the outer surface of the double-acting screw 84. Each slider 85 has a top rod 86 hinged at both ends, and one end of the top rod 86 is hinged to the first housing 1.

[0044] By activating the second motor 81 in either the forward or reverse direction, the second worm gear 82 rotates in either direction. The second worm gear 82 then rotates the second worm wheel 83 in either direction, which in turn rotates the bidirectional lead screw 84 in either direction. The bidirectional lead screw 84 then moves the two sliders 85 closer to or further apart from each other. The sliders 85 then move the push rod 86 in either the forward or reverse direction, ultimately causing the first housing 1 to rise or fall. This completes the up-and-down adjustment of the massage head 2's height. By reciprocating the up-and-down movement of the massage head 2, the massage head 2 can be raised and lowered to meet the different needs of the user.

[0045] like Figure 2 , Figure 4 and Figure 6 As shown, one side wall of the first housing 1 is arc-shaped, and one end of the two push rods 86 is hinged to both ends of the arc-shaped side wall of the first housing 1.

[0046] By setting it up in this way, the distance between the push rods 86 at both ends of the slider 85 can be shortened, thereby minimizing the width of the second housing 7 and thus minimizing the overall size of the massager.

[0047] like Figure 2 and Figure 6 As shown, it also includes several limiting members 71 provided in the second housing 7. Each pair of opposing push rods 86 are in contact with the limiting member 71 on the side away from each other. With this arrangement, the push rods 86 can be horizontally limited, thereby preventing the push rods 86 from shifting in the horizontal direction and making their swing more stable.

[0048] like Figure 1 As shown, it also includes a lumbar support plate 9, on which a sliding groove is provided. A rack 10 is symmetrically installed on the inner wall of the sliding groove. The second housing 7 is provided with a walking drive mechanism and a walking gear (the specific walking drive mechanism driving the walking gear to rotate is existing technology and will not be described in detail here). The walking gear meshes with the rack 10. Specifically, the second housing 7 is installed on the lumbar support plate 9 to form a walking massager. The second housing 7 moves along the length of the rack 10. In this way, when the back of the person is facing the lumbar support plate 9, massage can be performed on different parts of the back of the person.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
