Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a dumbbell. Background Technology

[0002] As material life becomes increasingly abundant, more and more people realize the importance of physical health, and many people have begun to pay attention to physical exercise. Dumbbells are a type of fitness equipment that is widely praised by fitness enthusiasts for their small size and ease of operation.

[0003] Before engaging in fitness activities, people sometimes need to warm up. For example, in winter, due to the cold weather, local muscle groups are prone to stiffness due to poor blood circulation. If one suddenly starts exercising at this time, problems such as muscle strains are likely to occur. Therefore, it is necessary to warm up specific areas of the body. However, since the muscle groups that are prone to stiffness are often in areas of the body that are not frequently used, the warm-up process takes a lot of time, affecting the enthusiasm of fitness enthusiasts. During fitness activities, problems such as sprained ankles, muscle tears, and muscle strains are unavoidable. When these problems occur, cold compresses are often used to solve them. However, due to the limitations of the fitness environment (such as when exercising outdoors), it is sometimes difficult to find items available for cold compresses, causing inconvenience.

[0040] Please refer to Figures 1 to 5 A dumbbell includes a body 1 and a temperature-changing component. The body 1 has an electrically connected main control board 2 and a battery 3. The temperature-changing component is provided at at least one end of the body 1. The temperature-changing component is used to change the temperature of the end of the body 1. The temperature-changing component is electrically connected to the main control board 2. The temperature-changing component is a semiconductor cooling chip 4 or a heating component 5.

[0041] In this embodiment, one end of the body 1 is provided with the semiconductor cooling chip 4, and the other end of the body 1 is provided with the heating component 5. That is to say, the dumbbell in this embodiment has both heat therapy and cold therapy functions. In other embodiments, the body 1 may only have the temperature-changing component at one end. In this case, the temperature-changing component can be either the heating component 5 or the semiconductor cooling chip 4. When the temperature-changing component is the heating component 5, the dumbbell has a heat therapy function; when the temperature-changing component is the semiconductor cooling chip 4, the dumbbell has a cold therapy function.

[0042] Optionally, the main body 1 is provided with control keys 6 electrically connected to the main control board 2. The control keys 6 are used to control the temperature-changing component. Specifically, the control keys 6 include an on / off key for controlling the opening and closing of the temperature-changing component and a setting key for setting the temperature of the temperature-changing component. In actual products, the main control board 2 can also be equipped with a wireless transmission module. In this case, the user can wirelessly control the opening and closing of the temperature-changing component and its operation through an external terminal device. The wireless transmission module includes, but is not limited to, a Bluetooth transmission module.

[0043] The main control board 2 includes a PCB board and a microcontroller unit (MCU) and a PWM circuit on the PCB board, and the temperature variable component is connected to the PWM circuit.

[0044] The main body 1 includes a main housing 11 and an end cap 12. The end cap 12 is provided at both ends of the main housing 11, and the temperature-changing component is provided on the end cap 12.

[0045] Preferably, the temperature-changing component is located outside the end cap 12. The dumbbell also includes a metal decorative cover 7, which is connected to the body 1. The metal decorative cover 7 is located outside the temperature-changing component and contacts and covers the temperature-changing component. In actual products, the metal decorative cover 7 can be directly connected to the body 1 or indirectly connected to the body 1 through the temperature-changing component. The metal decorative cover 7 serves both a decorative and heat-conducting function.

[0046] The heating component 5 includes a heating element 51 and a heat-insulating foam 52. The heating element 51 is located on the outside of the heat-insulating foam 52. The heat-insulating foam 52 can retain heat and reduce the heat generated by the heating element 51 from being transferred to the middle of the body 1, so that most of the heat can be retained at the end of the body 1 to improve heat utilization and reduce heat waste.

[0047] The heating element 51 is an aluminum substrate heating element. The aluminum substrate heating element is an existing and mature heating element for heating. Its purchase cost is low, which helps to control the manufacturing cost of dumbbells.

[0048] Optionally, the body 1 has a first NTC temperature sensor (not shown in the figure) at the end with the temperature-changing component. The first NTC temperature sensor is electrically connected to the main control board 2 and is used to collect temperature data at the end of the body 1 with the temperature-changing component. The body 1 also has a display window, and the main control board 2 has a digital display module 21 corresponding to the display window. The digital display module 21 can be used to display the temperature data sent by the first NTC temperature sensor, so that the user can know the temperature of the dumbbell end and make it convenient for the user to adjust the cooling and / or heating temperature of the dumbbell.

[0049] In actual products, the first NTC temperature sensor can directly contact the metal decorative cover 7 to obtain more accurate temperature data.

[0050] Furthermore, the main body 1 is provided with a second NTC temperature sensor (not shown in the figure) electrically connected to the main control board 2. The second NTC temperature sensor is located away from the temperature-changing component and is used to collect ambient temperature data. In this embodiment, the second NTC temperature sensor is located in the middle section of the main housing 11. In actual products, when the user sets the operating temperature of the thermoelectric cooler 4, the set temperature should be lower than the temperature collected by the second NTC temperature sensor. Through the control of the MCU, the user cannot adjust the set temperature to be higher than the temperature collected by the second NTC temperature sensor. When the user sets the operating temperature of the heating component 5, the set temperature should be higher than the temperature collected by the second NTC temperature sensor. Through the control of the MCU, the user cannot adjust the set temperature to be lower than the temperature collected by the second NTC temperature sensor.

[0051] To facilitate cold / hot compress operations, the dumbbell body 1 should be lightweight. Optionally, the dumbbell also includes a counterweight assembly 8, which is detachably mounted on the end of the body 1. Specifically, the counterweight assembly 8 includes a shell and a counterweight body disposed within the shell. The shell has a protrusion 81, and the protrusion 81 is provided with a locking structure 82. The end face of the body 1 is provided with a groove 13 that mates with the protrusion 81. The groove 13 is provided with a mating structure 14 that mates with the locking structure 82. The mating of the locking structure 82 and the mating structure 14 allows the counterweight assembly 8 to be detachably connected to the body 1. For example, in this embodiment, the locking structure 82 is a thread.

[0052] It is easy to understand that when the end face of the body 1 has the groove 13, the temperature-changing component is arranged around the groove 13.

[0053] To charge the battery 3, the main body 1 is provided with a charging interface 9 that is electrically connected to the main control board 2. The type of the charging interface 9 can be Type-C, micro USB, etc. To protect the charging interface 9, it is preferable that the charging interface 9 is located in the groove 13.

[0054] The above are merely optional embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the contents of this utility model specification and drawings under the utility model concept, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
