Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a massager. Background Technology

[0002] Massage helps relieve physical and mental fatigue, especially acupressure, which can promote health and relaxation. For example, massaging the temples can quickly relax the brain and may also help prevent colds, headaches, and dizziness. Massaging the skin around the eyes or face can accelerate blood circulation and delay or prevent the formation of wrinkles around the eyes.

[0003] There are many types of small massage products on the market that massage acupoints, but most of them use vibration to massage acupoints. There are also many structural solutions for providing vibration. The traditional solution uses an eccentric structure, where the eccentric block is directly connected to the motor output shaft. The characteristic of this structure is that the eccentric block is relatively close to the motor. Taking a massage product for the temples as an example, if the acupoint massage end, which is smaller than a finger, is to accommodate both the eccentric block and the motor, the product cannot be made very small. Furthermore, given the same eccentric block size, a larger motor is needed to achieve a better vibration massage effect. Utility Model Content

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, this is a preferred embodiment of the present invention, which provides a massager 100. The massager 100 is a small massage device that can provide massage to the skin around the eyes or face, so as to accelerate blood circulation in the skin around the eyes and delay / prevent the formation of wrinkles around the eyes.

[0028] like Figure 1 , Figure 2 , Figure 3As shown, the massager 100 includes a handheld part 110 and a massage part 120. The handheld part 110 is equipped with a motor 113, a power supply 114, a control circuit 115, and a control button 111. The control button 111 and the motor 113 are electrically connected to the control circuit 115 to control the operation of the massage part 120 (such as controlling the massage frequency of the massage part 120) through the control button 111. The handheld part 110 and the massage part 120 are connected to each other and fixed into an integral structure. Specifically, the handheld part 110 includes a first housing 112 and a charging interface 1121 exposed in the first housing 112. The motor 113, the power supply 114, and the control circuit 115 are located inside the first housing 112, while the control button 111 is exposed outside the first housing 112. The power supply 114 is used to supply power to the motor 113 and the control circuit 115, and the charging interface 1121 is used to charge the power supply 114. The massage part 120 includes a second housing 121 with a cavity 1213 and an eccentric block 122 disposed within the cavity 1213. The eccentric block 122 is located at one end of the second housing 121 and can rotate within the second housing 121. The end of the eccentric block 122 in the second housing 121 has a small structure (about 5mm). The massager 100 also includes a first connector 117 and shock-absorbing silicone 118. The first housing 112 and the second housing 121 are connected by the first connector 117. A connecting shaft 123 is connected between the eccentric block 122 and the output shaft 1131 of the motor 113. The connecting shaft 123 has a slender rod-like structure and is preferably made of POM material, nylon material, or a spring shaft.

[0029] like Figure 2 , Figure 3 , Figure 6 , Figure 7As shown, the first connector 117 is partially connected to the second housing 121 and partially connected to the first housing 112. The first connector 117 has a through hole 1171, through which the connecting shaft 123, connected to the output shaft 1131, passes to connect to the eccentric block 122. Shock-absorbing silicone 118 is disposed between the first housing 112 and the first connector 117 to reduce vibration in the handheld part 110 when the eccentric block 122 is in operation. The portion of the first connector 117 connecting to the second housing 121 has an elastic grip 1172, and the inner surface of the second housing 121 has a latch 1212 that matches the elastic grip 1172. The first connector 117 and the second housing 121 are fixedly connected by the engagement of the elastic grip 1172 and the latch 1212. The first connector 117 has an annular groove 1173 on the portion connecting to the first housing 112. The inner surface of the shock-absorbing silicone 118 has a first protruding ring 1181 that matches the annular groove 1173. The shock-absorbing silicone 118 is annular and is fitted onto the portion of the first connector 117 that connects to the first housing 112. The first protruding ring 1181 is located within the annular groove 1173. A fixing rib 1174 also protrudes from the annular groove 1173. The radial extension height of the fixing rib 1174 is the same as the depth of the annular groove 1173. The first protruding ring 1181 has a cutout 1182 that matches the fixing rib 1174. The shock-absorbing silicone 118 covers the fixing rib 1174, and the fixing rib 1174 is located within the cutout 1182. Since the fixing rib 1174 and the first housing 112 are not easily or not deformed, even with the presence of the shock-absorbing silicone 118, the fixing rib 1174 can make the connection between the first connector 117 and the first housing 112 more secure.

[0030] like Figure 4 , Figure 5 As shown, one end of the eccentric block 122 is connected to the second housing 121, and the other end is connected to the shaft 123. A protrusion 1221 is provided at the end of the eccentric block 122 connected to the second housing 121, and a limiting hole 1211 is provided at one end of the second housing 121 to mate with the protrusion 1221. The protrusion 1221 and the limiting hole 1211 are in clearance fit. A second connecting member 124 is provided at the connection end of the connecting shaft 123 and the eccentric block 122. A second protruding ring 1241 is provided on the outer surface of the second connecting member 124, and the second protruding ring 1241 abuts against or has clearance fit with the inner surface of the second housing 121. The second protruding ring 1241 allows the eccentric block 122 to rotate stably within the second housing 121.

[0031] like Figure 2As shown, the first housing 112 is further provided with a flexible sleeve 116 on its exterior. After the first housing 112 and the second housing 121 are connected, the end face of the second housing 121 abuts against the flexible sleeve 116. The flexible sleeve 116 has a storage cavity 1161 for storing external components at one end facing away from the massage part 120. The flexible sleeve 116 makes the user's hand more comfortable and can also absorb the vibration generated by the operation of the massage part 120. The flexible sleeve 116 can be made of flexible silicone material.

[0032] In this embodiment, the connecting shaft 123 is a spring shaft, the second housing 121 is in an upright state by default, and the portion of the second housing 121 that sleeves the connecting shaft 123 is made of a deformable material. In other embodiments, such as Figure 8 As shown, when the connecting shaft 123 is a spring shaft, the massage part 120 has a preset bend, and the second housing 121 is in a bent state by default. The connecting end of the connecting shaft 123 and the output shaft 1131 is provided with a plug 125, which is detachably connected to the output shaft 1131 after passing through the through hole 1171.

[0033] Because a connecting shaft 123 connects the eccentric block 122 and the output shaft of the motor 113, and the connecting shaft 123 is a slender rod-like structure, the slender connecting shaft 123 can amplify the vibration of the eccentric block, resulting in a better vibration effect compared to existing technologies. Furthermore, because the connecting shaft 123 is made of acetal or nylon, it possesses good rigidity, meeting the requirements for long-term use of the slender connecting rod. When a spring shaft is used, the angle between the eccentric block 122 and the motor 113 can also be changed.

[0034] The above specific examples illustrate the principles and implementation methods of this utility model. It should be understood that the above implementation methods are only for the purpose of helping to understand this utility model and should not be construed as limiting this utility model. For those skilled in the art, any minor improvements or equivalent substitutions made to the structural form or construction of this utility model based on the concept of this utility model should be included within its protection scope.
