Description

Temperature sensor structure of the massage module

[0001] The present invention relates to a temperature sensor structure of a massage module, and more particularly, to a temperature sensor structure of a massage module that can improve the accuracy of temperature measurement of a massage ball by providing a bracket in which a temperature sensor is placed on a module plate to which a massage ball is coupled, thereby bringing the temperature sensor into direct contact with the massage ball.

[0002] Thermal massage devices are devices designed to relieve acute or chronic pain that occurs in the muscles and nerve tissues of the spinal area. Recently, various types of spinal thermal massage devices have been developed.

[0003] Thermal massage devices can be moved along body parts to improve blood circulation or relieve temporary muscle tension. Furthermore, the heat generated by the thermal massage device can be used to apply thermal stimulation to painful areas, improving blood flow and alleviating pain.

[0004] A thermal massage device includes a heat-generating massage ball that applies heat stimulation while applying pressure to the user. The center of the massage ball may include a PTC heater that heats when current is applied.

[0005] The massage balls of a thermal massage device can be heated to a specified temperature, and the thermal massage device can be equipped with a temperature sensor for heating the massage balls to the specified temperature. Specifically, the heating level of the massage balls can be changed based on the temperature measured by the temperature sensor, thereby heating the massage balls to the specified temperature.

[0006] However, the temperature sensor equipped in the conventional thermal massage device has the following problems. The temperature sensor equipped in the conventional thermal massage device may be installed in the module plate to which the massage balls are coupled, and the temperature sensor may be placed apart from the massage balls.

[0007] The heat generated from the PTC heater provided in the massage ball is transferred to the outer cover of the massage ball, and the heat transferred to the outer cover of the massage ball can be transferred to the module plate. A temperature sensor provided in a conventional thermal massage device can be provided in the module plate, and the temperature sensor measures the heat transferred from the PTC heater - massage ball - outer cover - module plate.

[0008] However, measuring the temperature of the module plate using a temperature sensor in this manner presents a problem in that it is difficult to precisely control the temperature of the massage ball. Specifically, the massage ball, outer cover, and module plate may have different heat transfer rates, resulting in inconsistent heat transfer and heat transfer time between the PTC heater, massage ball, outer cover, and module plate.

[0009] Accordingly, it becomes difficult to accurately determine the temperature of the massage ball through the temperature sensor when the temperature of the massage ball rises or falls. This difficulty in accurately determining the temperature of the massage ball through the temperature sensor can lead to overshooting in the heating of the massage ball, and the resulting temperature deviation can be problematic.

[0010] In addition, since the heat transfer rates of the massage ball, the exterior cover, and the module plate are different from each other, the heat transfer and heat transfer time become inconsistent, making it difficult to control the temperature of the massage ball using the PID control method.

[0011] The present invention is intended to solve the above-described problem, and more specifically, relates to a temperature sensor structure of a massage module that can improve the accuracy of temperature measurement of a massage ball by providing a bracket in which a temperature sensor is placed on a module plate to which a massage ball is coupled, thereby bringing the temperature sensor into direct contact with the massage ball.

[0012] A temperature sensor structure of a massage module according to one embodiment is a temperature sensor structure for measuring the temperature of a massage ball provided in a massage module, characterized by including: a module plate having a plate shape and having a massage ball attached to one side; a bracket attached to the module plate and positioned at a lower portion of the massage ball; and a temperature sensor provided on the bracket and in contact with a lower portion of the massage ball.

[0013] The bracket of the temperature sensor structure of the massage module according to one embodiment includes a mounting groove in which the temperature sensor is mounted, a support portion that supports the temperature sensor at a lower portion of the mounting groove, and mounting protrusions that support the temperature sensor at both sides of the mounting groove, wherein the mounting protrusions and the support portion can extend in the longitudinal direction while protruding outward from the module plate.

[0014] In one embodiment, the support portion of the temperature sensor structure of the massage module may be provided with a support portion that supports the end of the temperature sensor in the longitudinal direction.

[0015] The support portion of the temperature sensor structure of the massage module according to one embodiment may be provided with a flat portion having a flat surface shape.

[0016] The mounting jaw of the temperature sensor structure of the massage module according to one embodiment includes a first mounting jaw provided on one side of the mounting groove and a second mounting jaw provided on the other side of the mounting groove, and the lengths of the first mounting jaw and the second mounting jaw may be formed differently.

[0017] In one embodiment, the temperature sensor of the temperature sensor structure of the massage module is in contact with the massage ball in a diagonal direction with respect to a line extending vertically from the center of the massage ball, and the length of the second mounting jaw may be formed longer than the length of the first mounting jaw.

[0018] The temperature sensor of the temperature sensor structure of the massage module according to one embodiment is formed in a cylindrical shape, and the mounting protrusions provided on both sides of the mounting groove can be extended in an arc shape.

[0019] The length of the mounting jaw formed in the shape of an arc of the temperature sensor structure of the massage module according to one embodiment may be longer than 1 / 4 and shorter than 1 / 2 of the circumference of the temperature sensor.

[0020] The upper part of the mounting jaw of the temperature sensor structure of the massage module according to one embodiment may be chamfered to form a chamfered portion.

[0021] The bracket of the temperature sensor structure of the massage module according to one embodiment may include a first reinforcing plate that supports the lower part of the support and extends in the vertical direction.

[0022] The bracket of the temperature sensor structure of the massage module according to one embodiment includes a main body part coupled to the module plate, and a second reinforcing plate having a box shape and having an empty space formed therein and coupled to the main body part, wherein the first reinforcing plate is arranged inside the second reinforcing plate, and the lower portion of the first reinforcing plate can be supported by a support member that is provided on the lower portion of the second reinforcing plate and extends in the width direction.

[0023] The present invention relates to a temperature sensor structure of a massage module, and has the advantage of improving the accuracy of temperature measurement of a massage ball by providing a bracket in which a temperature sensor is placed on a module plate to which a massage ball is coupled, thereby bringing the temperature sensor into direct contact with the massage ball.

[0024] In addition, the present invention has an advantage in that it can reduce vibrations of a temperature sensor in the up-and-down direction, width direction, and length direction through a massage ball and a support part provided on the bracket, a first and second support jaws provided on both sides of the bracket's support groove, and a support part provided on the support part.

[0025] In addition, the present invention has the advantage of being able to prevent interference between the user and the bracket by allowing the temperature sensor to contact the massage ball in a diagonal direction with respect to a line extending vertically from the center of the massage ball by forming the first and second mounting jaws to have different lengths.

[0026] In addition, the present invention has the advantage of being able to increase the contact area between the temperature sensor and the massage ball while stably supporting the temperature sensor by forming the first and second mounting jaws to have different lengths.

[0027] In addition, the present invention has an advantage in that it is possible to prevent the temperature sensor from being detached from the bracket by forming the length of the fixing jaw to be longer than 1 / 4 and shorter than 1 / 2 of the circumference of the temperature sensor while only protruding a portion of the temperature sensor from the bracket.

[0028] In addition, the present invention has the advantage of improving the precision of temperature control by controlling the temperature of the heater using the PID (proportional, integral, differential) method through the temperature measured by the temperature sensor.

[0043] The present invention relates to a temperature sensor structure for a massage module, and more particularly, to a temperature sensor structure for a massage module, which comprises a bracket for placing a temperature sensor on a module plate to which a massage ball is coupled, thereby allowing the temperature sensor to come into direct contact with the massage ball, thereby improving the accuracy of temperature measurement of the massage ball. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.

[0044] A temperature sensor structure of a massage module according to an embodiment of the present invention includes a module plate (110), a bracket (130), and a temperature sensor (120).

[0045] Referring to FIG. 1, a massage module (10) according to an embodiment of the present invention may be equipped with a massage ball (20) that generates heat while applying pressure to a user. The massage ball (20) is equipped with a heater (21), and the heater (21) is provided inside the massage ball (20) and can supply heat to the massage ball (20).

[0046] The above massage module (10) may be equipped with a plurality of massage balls (20), and the massage balls (20) may be coupled to the module plate (110) equipped in the massage module (10).

[0047] Referring to Fig. 2, the module plate (110) has a plate shape and the massage ball (20) is coupled to one side. The module plate (110) may be a plate-shaped member coupled to the massage module (10), and supports the massage ball (20) through the module plate (110).

[0048] Referring to FIGS. 2 and 3, the bracket (130) is coupled to the module plate (110) and is positioned at the bottom of the massage ball (20). The bracket (130) is provided with a mounting groove (141) in which the temperature sensor (120) can be mounted, and the bracket (130) can be positioned at the bottom of the massage ball (20).

[0049] The temperature sensor (120) is provided on the bracket (130) and comes into contact with the lower portion of the massage ball (20). The temperature sensor (120) can measure the temperature of the massage ball (20), and the temperature sensor (120) may be an NTC (Negative Temperature Coefficient of Resistance) sensor whose resistance value decreases as the temperature increases. However, the present invention is not limited thereto, and the temperature sensor (120) may be formed of various types of sensors as long as it can measure the temperature of the massage ball (20).

[0050] The temperature sensor structure of the massage module according to an embodiment of the present invention is provided with the bracket (130) on which the temperature sensor (120) is mounted on the module plate (110), so that the temperature sensor (120) can directly contact the massage ball (20).

[0051] By directly contacting the temperature sensor (120) with the massage ball (20) and measuring the temperature of the massage ball (20) through the temperature sensor (120), the temperature value of the massage ball (20) can be accurately measured.

[0052] Referring to Fig. 3, the massage ball (20) is provided with a heater (21) inside, and the heater (21) may be a PTC heater. However, the present invention is not limited thereto, and the heater provided in the massage ball (20) may be various types of heaters as long as they can heat the massage ball (20).

[0053] As the heater (21) is provided inside the massage ball (20), the massage ball (20) can be directly heated by the heater (21). The heater (21) is placed at the center of the massage ball (20), and the heat generated from the heater (21) is radially transmitted to the center of the massage ball (20).

[0054] Referring to FIGS. 3 and 4, the temperature sensor (120) can be in direct contact with a lower portion of one side of the massage ball (20). Since the heat generated from the heater (21) is radially transferred to the center of the massage ball (20), the point where the user and the massage ball (20) come into contact and the point where the massage ball (20) and the temperature sensor (120) come into contact form the same temperature. Therefore, by measuring the temperature of the massage ball (20) through the temperature sensor (120), the temperature at which the massage ball (20) and the user come into contact can be accurately measured.

[0055] Referring to FIGS. 4 and 5, the bracket (130) may include a mounting groove (141), a support portion (150), and a mounting protrusion (160). The mounting groove (141) may be a groove in which the temperature sensor (120) is mounted.

[0056] The above bracket (130) may further include a main body (140) that is coupled to the module plate (110), and the main body (140) may be coupled to the module plate (110) via a bolt or the like. The mounting groove (141) is provided in the main body (140), and the temperature sensor (120) may be mounted in the mounting groove (141).

[0057] The above temperature sensor (120) can be supplied with power by being connected to a cable (121). Referring to Fig. 3, the cable (121) can be connected to the outside by extending from the mounting groove (141) toward the outside of the bracket (130).

[0058] The above-mentioned support portion (150) may be a portion that supports the temperature sensor (120) at the lower portion of the above-mentioned mounting groove (141). Referring to Fig. 5, the support portion (150) may be a lower point of the above-mentioned mounting groove (141), and the lower portion of the temperature sensor (120) is supported through the support portion (150).

[0059] The above-mentioned mounting protrusion (160) may support the temperature sensor (120) on both sides of the mounting groove (141). Referring to Fig. 5, the mounting protrusion (160) may be a support protrusion formed on both sides of the mounting groove (141), and the both sides of the temperature sensor (120) are supported through the mounting protrusion (160).

[0060] Referring to FIG. 6, the mounting protrusion (160) and the support portion (150) can extend in the longitudinal direction while protruding outward from the module plate (110). As the mounting protrusion (160) and the support portion (150) extend in the longitudinal direction and protrude outward from the module plate (110), the temperature sensor (120) can be positioned while extending outward from the module plate (110).

[0061] By arranging the temperature sensor (120) so as to extend to the outside of the module plate (110), the contact area between the temperature sensor (120) and the massage ball (20) can be increased.

[0062] Here, the longitudinal direction may refer to a direction extending outward from the module plate (110) based on FIGS. 5 and 6. In addition, the width direction may refer to a direction in which the mounting groove (141) extends left and right based on FIG. 5. In addition, the up-down direction may refer to a direction in which the mounting groove (141) extends up and down based on FIG. 5.

[0063] As described above, the temperature sensor (120) measures the temperature of the massage ball (20) by making direct contact with the massage ball (20). When the temperature sensor (120) is installed in the installation groove (141) of the bracket (130), a portion of the temperature sensor (120) must protrude outside the bracket (130) in order to bring the temperature sensor (120) and the massage ball (20) into direct contact.

[0064] Therefore, it is preferable that the length of the mounting protrusion (160) of the bracket (130) be formed to be smaller than the height of the temperature sensor (120). As the length of the mounting protrusion (160) is formed to be smaller than the height of the temperature sensor (120), an upper portion of the temperature sensor (120) can protrude outward from the bracket (130), thereby allowing the temperature sensor (120) to come into contact with the massage ball (20).

[0065] Referring to FIGS. 6 and 7, the temperature sensor (120) according to an embodiment of the present invention may be formed in a cylindrical shape, and the mounting protrusions (160) provided on both sides of the mounting groove (141) may extend in an arc shape. Specifically, the interior of the mounting groove (141) may be formed as an arc-shaped groove so that the temperature sensor (120) formed in a cylindrical shape can be mounted therein.

[0066] According to an embodiment of the present invention, the length of the mounting protrusion (160) formed in an arc shape may be longer than 1 / 4 and shorter than 1 / 2 of the circumference of the temperature sensor (120). Here, the circumference of the temperature sensor (120) may be the circumference length of a circular cross section of the temperature sensor (120) formed in a cylindrical shape.

[0067] As described above, the length of the mounting bracket (160) must be formed to be smaller than the height of the temperature sensor (120) so that the temperature sensor (120) can protrude outward from the bracket (130).

[0068] At this time, if the length of the mounting protrusion (160) formed in an arc shape is shorter than 1 / 4 of the circumference of the temperature sensor (120), there is a risk that the temperature sensor (120) may come off from the mounting groove (141).

[0069] Specifically, if the length of the extended mounting protrusion (160) is shorter than 1 / 4 of the circumference of the temperature sensor (120), the height of the extended mounting protrusion (160) is formed lower than the center point of the temperature sensor (120). In this case, since the side of the temperature sensor (120) cannot be stably supported by the mounted mounting protrusion (160), there is a risk that the temperature sensor (120) may fall out of the mounted groove (141).

[0070] However, if the length of the above-mentioned fixing jaw (160) is longer than 1 / 4 of the circumference of the temperature sensor (120), the height of the above-mentioned fixing jaw (160) is formed higher than the center point of the temperature sensor (120).

[0071] In this way, when the height at which the mounting jaw (160) extends is formed higher than the center point of the temperature sensor (120), the temperature sensor (120) is held by the curvature of the mounting jaw (160) formed in an arc shape, thereby preventing the temperature sensor (120) from being detached.

[0072] In addition, if the length of the mounting bracket (160) formed in an arc shape is longer than half of the circumference of the temperature sensor (120), the temperature sensor (120) may not protrude outward from the bracket (130).

[0073] Specifically, if the length of the extension of the mounting bracket (160) is longer than half of the circumference of the temperature sensor (120), the height of the extension of the mounting bracket (160) is formed to be the same as the height of the temperature sensor (120), and the temperature sensor (120) may not protrude outward from the bracket (130).

[0074] Therefore, it is preferable that the length of the mounting bracket (160) formed in an arc shape is longer than 1 / 4 and shorter than 1 / 2 of the circumference of the temperature sensor (120).

[0075] Referring to FIGS. 6 and 7, the upper portion of the mounting protrusion (160) according to an embodiment of the present invention may be chamfered to form a chamfered portion (163). The mounting protrusion (160) may support the side of the temperature sensor (120), and the temperature sensor (120) may protrude outward from the bracket (130) and come into contact with the massage ball (20).

[0076] When the temperature sensor (120) comes into contact with the massage ball (20), there is a risk that interference may occur between the mounting jaw (160) and the massage ball (20). However, if the chamfered portion (163) is formed on the upper portion of the mounting jaw (160) as in the embodiment of the present invention, interference between the mounting jaw (160) and the massage ball (20) can be prevented.

[0077] According to an embodiment of the present invention, the temperature sensor (120) may be protruded outward from the bracket (130) and may be in direct contact with the massage ball (20). If the temperature sensor (120) is in direct contact with the massage ball (20), there is a risk that vibration may occur in the temperature sensor (120) due to an impact applied to the massage ball (20).

[0078] Specifically, the massage ball (20) can be rotatably coupled to the module plate (110), and the massage ball (20) can come into contact with a user. The massage ball (20) rotates with respect to the module plate (110) when it comes into contact with a user, and at this time, an impact can be applied from the massage ball (20) to the temperature sensor (120).

[0079] When an impact is applied from the massage ball (20) to the temperature sensor (120), vibration occurs in the temperature sensor (120). When vibration occurs in the temperature sensor (120), a point occurs where the temperature sensor (120) and the massage ball (20) come apart, and the temperature of the massage ball (20) cannot be accurately measured through the temperature sensor (120).

[0080] Referring to FIGS. 7 and 8, the bracket (130) according to an embodiment of the present invention can support the temperature sensor (120) while reducing vibration generated from the temperature sensor (120).

[0081] Specifically, the bracket (130) according to an embodiment of the present invention can reduce the up-and-down vibration of the temperature sensor (120) through the support portion (150). Referring to FIG. 7, the lower portion of the temperature sensor (120) can be supported through the support portion (150), and at this time, the upper portion of the temperature sensor (120) can be supported while making contact with the massage ball (20).

[0082] In this way, by supporting the lower and upper parts of the temperature sensor (120) through the support part (150) and the massage ball (20), the up-and-down vibration of the temperature sensor (120) can be reduced.

[0083] According to an embodiment of the present invention, the support portion (150) may be provided with a flat portion (151) formed in a flat surface shape. The flat portion (151) may be formed in a flat surface shape and may be a point that comes into contact with the lower portion of the temperature sensor (120).

[0084] When supporting the lower part of the temperature sensor (120) through the above-mentioned support part (150), the lower part of the temperature sensor (120) can be stably supported by bringing the flat part (151) into contact with the lower part of the temperature sensor (120).

[0085] In addition, by providing the flat portion (151) formed in a flat surface shape on the support portion (150), the temperature sensor (120) can be stably installed in the mounting groove (141).

[0086] The bracket (130) according to an embodiment of the present invention can reduce the width direction vibration of the temperature sensor (120) through the mounting protrusion (160). Referring to Fig. 7, the mounting protrusion (160) may include a first mounting protrusion (161) provided on one side of the mounting groove (141) and a second mounting protrusion (162) provided on the other side of the mounting groove (141).

[0087] By providing the first mounting protrusion (161) and the second mounting protrusion (162) on both sides of the mounting groove (141), it is possible to support both sides of the temperature sensor (120) mounted in the mounting groove (141). This makes it possible to reduce the width-wise vibration of the temperature sensor (120).

[0088] Referring to FIG. 8, the support member (150) according to an embodiment of the present invention may be provided with a support member (170) that supports the end of the temperature sensor (120) in the longitudinal direction.

[0089] The above support member (170) supports the end of the temperature sensor (120) by making contact with the end of the temperature sensor (120), and the longitudinal vibration of the temperature sensor (120) can be reduced through the support member (170).

[0090] Specifically, one end of the temperature sensor (120) can be in contact with the support (170) in the longitudinal direction, and the other end of the temperature sensor (120) can be in contact with the main body (140) of the bracket (130).

[0091] In this way, by bringing one end and the other end of the temperature sensor (120) into contact with the support (170) and the main body (140) in the longitudinal direction, one end and the other end of the temperature sensor (120) can be supported through the support (170) and the main body (140). This makes it possible to reduce longitudinal vibration of the temperature sensor (120).

[0092] Referring to FIG. 4, the temperature sensor (120) can be brought into contact with the massage ball (20) in a diagonal direction with respect to a line extending vertically from the center of the massage ball (20). The massage ball (20) is brought into contact with the user, and in order to prevent interference between the user and the temperature sensor (120) when the massage ball (20) comes into contact with the user, it is preferable to place the temperature sensor (120) on the inside of the massage ball (20).

[0093] For this purpose, the temperature sensor (120) can be brought into contact with the massage ball (20) in a diagonal direction with respect to a line extending vertically from the center of the massage ball (20).

[0094] According to an embodiment of the present invention, the lengths of the first mounting protrusion (161) and the second mounting protrusion (162) may be formed differently. Specifically, the length of the second mounting protrusion (162) may be formed to be longer than the length of the first mounting protrusion (161).

[0095] As described above, in order to prevent interference between the user and the temperature sensor (120) when the massage ball (20) comes into contact with the user, the temperature sensor (120) may come into contact with the massage ball (20) in a diagonal direction with respect to a line extending vertically from the center of the massage ball (20).

[0096] Referring to FIGS. 4 and 7, the length of the second mounting protrusion (162) can be formed longer than the length of the first mounting protrusion (161) in order to bring the temperature sensor (120) into contact with the massage ball (20) in a diagonal direction with respect to a line extending vertically from the center of the massage ball (20).

[0097] When the length of the first mounting jaw (161) and the length of the second mounting jaw (162) are formed to be the same, when the temperature sensor (120) comes into contact with the massage ball (20) in a diagonal direction with respect to a line extending vertically from the center of the massage ball (20), the contact area between the temperature sensor (120) and the massage ball (20) can be reduced.

[0098] However, if the length of the second mounting protrusion (162) is formed longer than the length of the first mounting protrusion (161), the contact area between the temperature sensor (120) and the massage ball (20) is formed larger, and both sides of the temperature sensor (120) can be supported through the first mounting protrusion (161) and the second mounting protrusion (162).

[0099] In this way, by forming the length of the second mounting protrusion (162) longer than the length of the first mounting protrusion (161), the temperature sensor (120) can be supported on both sides through the first mounting protrusion (161) and the second mounting protrusion (162), and the temperature sensor (120) can be brought into contact with the massage ball (20) in a diagonal direction with respect to a line extending vertically from the center of the massage ball (20).

[0100] In addition, according to an embodiment of the present invention, by forming the length of the second mounting jaw (162) longer than the length of the first mounting jaw (161), the temperature sensor (120) can be stably supported while increasing the contact area between the temperature sensor (120) and the massage ball (20).

[0101] Specifically, if the lengths of the first mounting bracket (161) and the second mounting bracket (162) are formed to be the same, the area where the temperature sensor (120) is exposed in the bracket (130) becomes smaller, and the temperature sensor (120) may not sufficiently contact the massage ball (20).

[0102] In order to increase the area exposed to the temperature sensor (120) in the bracket (130), the heights of the first mounting protrusion (161) and the second mounting protrusion (162) may be lowered. However, if the heights of the first mounting protrusion (161) and the second mounting protrusion (162) are lowered, it may be difficult to stably support the temperature sensor (120) through the first mounting protrusion (161) and the second mounting protrusion (162).

[0103] In order to solve this problem, the temperature sensor structure of the massage module according to an embodiment of the present invention may be formed so that the first mounting protrusion (161) and the second mounting protrusion (162) have different lengths. Specifically, the length of the second mounting protrusion (162) may be formed to be longer than the length of the first mounting protrusion (161).

[0104] By forming the length of the second mounting protrusion (162) longer than the length of the first mounting protrusion (161), the temperature sensor (120) can be stably supported through the relatively longer second mounting protrusion (162).

[0105] In addition, by increasing the area where the temperature sensor (120) is exposed on the bracket (130) through the first mounting protrusion (161) which is relatively shorter than the second mounting protrusion (162), the contact area between the temperature sensor (120) and the massage ball (20) can be increased.

[0106] According to an embodiment of the present invention, the external material of the temperature sensor (120) may be made of stainless steel. The massage ball (20) is in contact with the user, and the massage ball (20) may be rotatably coupled to the module plate (110).

[0107] The above massage ball (20) rotates with respect to the module plate (110) when it comes into contact with the user. At this time, friction may occur between the massage ball (20) and the temperature sensor (120). In order to prevent the temperature sensor (120) from being damaged by such friction, it is preferable that the external material of the temperature sensor (120) be made of stainless steel.

[0108] Referring to Fig. 9, the bracket (130) according to an embodiment of the present invention may include a first reinforcing plate (181) and a second reinforcing plate (182). Since the temperature sensor (120) is in direct contact with the massage ball (20), a large load is generated on the temperature sensor (120) and the bracket (130).

[0109] The first reinforcing plate (181) and the second reinforcing plate (182) may be members that support the load generated in the temperature sensor (120) and the bracket (130). The first reinforcing plate (181) supports the lower portion of the support portion (150), and the first reinforcing plate (181) may extend in the vertical direction.

[0110] A plurality of first reinforcing plates (181) may be provided at the lower portion of the above-mentioned support portion (150), and the support portion (150) and the temperature sensor (120) disposed on the upper portion of the support portion (150) may be supported through the plurality of first reinforcing plates (181).

[0111] The second reinforcing plate (182) has an empty space formed inside, and the second reinforcing plate (182) may be formed in a box shape. The second reinforcing plate (182) may be coupled to the main body (140), and the first reinforcing plate (181) may be placed inside the second reinforcing plate (182) formed in a box shape. The second reinforcing plate (182) supports the first reinforcing plate (181) that supports the support portion (150).

[0112] A support member (183) extending in the width direction may be provided at the lower portion of the second reinforcing plate (182). The support member (183) may extend in the width direction and support the lower portion of the first reinforcing plate (181).

[0113] Referring to FIG. 9, the first reinforcing plate (181) can be placed inside the second reinforcing plate (182), and when the first reinforcing plate (181) is placed inside the second reinforcing plate (182), the lower portion of the first reinforcing plate (181) can be supported by the support (183) that is provided at the lower portion of the second reinforcing plate (182) and extends in the width direction.

[0114] In this way, by providing the first reinforcing plate (181) and the second reinforcing plate (182) on the bracket (130), the support part (150) and the temperature sensor (120) arranged on the upper portion of the support part (150) can be supported through the first reinforcing plate (181) and the second reinforcing plate (182).

[0115] Referring to FIG. 10, the temperature sensor structure of the massage module according to an embodiment of the present invention may include a control unit (190) that controls the temperature of the heater (21) according to the temperature sensor (120).

[0116] The above control unit (190) controls the temperature of the heater (21) based on the temperature measured by the temperature sensor (120), thereby enabling the temperature of the massage ball (20) to be controlled.

[0117] According to an embodiment of the present invention, the control unit (190) can control the temperature of the heater (21) using a PID (proportional, integral, differential) method through the temperature measured by the temperature sensor (120).

[0118] The PID (proportional, integral, differential) control method can be a control method that fills in the error between the target value and the current value through proportional control, integral control, and differential control to reach the target value.

[0119] If the massage ball and the temperature sensor are not in direct contact, there is a problem in that it is difficult to control the temperature of the massage ball using the PID control method because the heat transfer and heat transfer time are not constant due to the different heat transfer rates of the massage ball, the outer cover, and the module plate.

[0120] However, the temperature sensor structure of the massage module according to an embodiment of the present invention can accurately measure the temperature of the massage ball (20) without time deviation by directly contacting the temperature sensor (120) with the massage ball (20).

[0121] Accordingly, the control unit (190) according to an embodiment of the present invention can control the temperature of the heater (21) and the massage ball (20) using a PID (proportional, integral, differential) method through the temperature measured by the temperature sensor (120).

[0122] However, it is not limited thereto, and the control unit (190) according to an embodiment of the present invention, as shown in FIG. 10, may control the temperature of the massage ball (20) by controlling the temperature of the heater (21) using a current input method according to time.

[0123] The temperature sensor structure of the massage module according to the embodiment of the present invention described above has the following effects.

[0124] The temperature sensor structure of the massage module according to an embodiment of the present invention has an advantage in that it can improve the accuracy of temperature measurement of the massage ball by having a bracket in which a temperature sensor is placed on a module plate to which a massage ball is coupled, thereby allowing the temperature sensor to come into direct contact with the massage ball.

[0125] In addition, the temperature sensor structure of the massage module according to an embodiment of the present invention has the advantage of being able to reduce vibrations of the temperature sensor in the up-and-down direction, width direction, and length direction through a support part provided on the massage ball and the bracket, a first and second support parts provided on both sides of the bracket's support groove, and a support part provided on the support part.

[0126] In addition, the temperature sensor structure of the massage module according to an embodiment of the present invention has the advantage of being able to contact the temperature sensor to the massage ball in a diagonal direction with respect to a line extending vertically from the center of the massage ball by forming the first and second mounting jaws with different lengths, thereby preventing interference between the user and the bracket.

[0127] The temperature sensor structure of the massage module according to an embodiment of the present invention has the advantage of being able to increase the contact area between the temperature sensor and the massage ball while stably supporting the temperature sensor by forming the first and second mounting jaws with different lengths.

[0128] In addition, the temperature sensor structure of the massage module according to an embodiment of the present invention has an advantage in that the temperature sensor can be prevented from being detached from the bracket by protruding only a portion of the temperature sensor from the bracket by forming the length of the mounting bracket to be longer than 1 / 4 and shorter than 1 / 2 of the circumference of the temperature sensor.

[0129] In addition, the temperature sensor structure of the massage module according to an embodiment of the present invention has the advantage of preventing interference between the bracket and the massage ball by forming a chamfered portion on the upper part of the mounting jaw.

[0130] In addition, the temperature sensor structure of the massage module according to an embodiment of the present invention has a flat surface-shaped portion on the support portion, thereby having the advantage of being able to support the lower portion of the temperature sensor while stably placing the temperature sensor in the support groove.

[0131] In addition, the temperature sensor structure of the massage module according to an embodiment of the present invention has an advantage in that the temperature sensor can be stably supported through the bracket by having a first reinforcing plate and a second reinforcing plate on the bracket.

[0132] In addition, the temperature sensor structure of the massage module according to an embodiment of the present invention has the advantage of improving the precision of temperature control by controlling the temperature of the heater using the PID (proportional, integral, differential) method through the temperature measured by the temperature sensor.

[0133] While the present invention has been described with reference to the embodiments illustrated in the drawings, these are merely exemplary, and those skilled in the art will appreciate that various modifications and variations of the embodiments are possible. Therefore, the true scope of technical protection of the present invention should be determined by the technical spirit of the appended claims.
