DETAILED DESCRIPTION

[0025] Technical solutions in the embodiments of the present disclosure will be clearly and completely described below by referring to the accompanying drawings in the embodiments of the present disclosure. Apparently, the described embodiments are only a part of, but not all of, the embodiments of the present disclosure. All other embodiments, which are obtained by any ordinary skilled person in the art based on the embodiments of the present disclosure without making any creative work, shall be within the scope of the present disclosure.

[0026] As shown in FIG. 1 to FIG. 7, a cold/warm-compression body care device includes a shell 1. The shell 1 includes a front shell 11 and a rear shell 12 that are connected with and covered to each other. A receiving cavity is defined between the front shell 11 and rear shell 12. The shell 1 defines an air inlet 111 and an air outlet 121. A conduction member 8 is embedded in the shell 1. The shell 1 defines a conduction through hole 123. The conduction member 8 covers the conduction through hole 123. A cold-and-warm semiconductor 7 is thermal-conductively connected to an inner side of the conduction member 8. A side of the cold-and-warm semiconductor 7 away from the conduction member 8 is thermal-conductively connected to a heat dissipator 5. An inner bracket 13 is arranged inside the shell 1. The heat dissipator 5 is fixedly mounted on the inner bracket 13 and is located at a middle of a plane of the shell 1. Two storage batteries 6 are arranged inside the shell 1. The two storage batteries 6 are symmetrically arranged on an upper side and a lower side of the heat dissipator 5. The heat dissipator 5 is made of aluminum alloy. The heat dissipator 5 includes a plurality of wings 51 parallel to each other. An air duct is defined between every two adjacent wings 51 of the plurality of wings. The air outlet 121 is located at an end of the air duct to reduce obstacles in an airflow path and to improve an air outletting efficiency. A fan assembly 3 is arranged inside the shell 1. The fan assembly 3 drives air located at the air inlet 111 to flow through the heat dissipator 5 to reach the air outlet 121 and to further flow out of the device. The heat dissipator 5 is arranged with a fan bracket 32. The fan assembly 3 is mounted on the fan bracket 32. The fan assembly 32 is configured to direct the air to flow towards the heat dissipator. The fan assembly 3 includes a centrifugal fan blade set 31. The centrifugal fan blade set 31 is located at an inner side of the air inlet 111. An area of a projection of the centrifugal fan blade set 31 onto the air inlet 111 is smaller than an area of the air inlet. In this way, a size of the air inlet 111 is maximized corresponding to the centrifugal fan blade set 31, and therefore, a maximum air source is provided. An air concentration hood 2 is arranged to surround a circumference of the centrifugal fan blade set 31. A height of the air concentration hood 2 is h1; and a height of each blade of the centrifugal fan blade set 31 is h2, where h1h2. Blades of the centrifugal fan blade set 31 do not extend beyond an edge of the air concentration hood 2 near the end of the air inlet 111. In this way, a returning airflow, which may interfere with operation of the centrifugal fan blade set 31, is prevented from being formed at the air inlet.

[0027] A circuit board assembly 4 is arranged inside the shell 1. The circuit board assembly 4 is electrically connected with a control button set 41 and a USB port 42. The control button set 41 and USB port 42 are arranged in through holes pre-defined in the shell 1 and extend outwardly from the through holes. The fan assembly 3 and the cold-and-warm semiconductor 7 are both electrically connected to the circuit board assembly 4. The control button set 41 is configured to control the body care device to operate in a cold compression mode, a warm compression mode, or in an alternating operation mode in which the cold compression and the warm compression are operating alternately. When the USB port 42 is connected to an external power supply through a cable, electric power is supplied to the storage batteries 6.

[0028] Strap connection portions 122 are symmetrically arranged on a left side and a right side of the shell 1 respectively. The strap connection portions 122 are configured to mount a strap assembly. The body care device is worn on the human body through the strap assembly.

[0029] In summary, in the present disclosure, the cold-and-warm semiconductor 7 is configured as the source to generate coldness and warmness. The storage batteries 6 are configured to provide power, such that the cold/warm-compression body care device is usable at any time when needed. The cold/warm-compression body care device provides body care at a constant temperature. Therefore, the cold/warm-compression body care device is used conveniently and provides a better body care effect. The centrifugal fan blade set 31 is arranged with the air concentration hood 2, and the air concentration hood 2 is configured to converge and rearrange the inlet air. In this way, the air is prevented from flowing backwards and channeling, a heat dissipation effect is improved. In addition, a size of an opening of the air concentration hood 2 defines a size of the air inlet 111. In this way, the air inlet 111 is maximized, the maximum amount of the inlet air is provided under restricted conditions, and the heat dissipation effect is improved. The heat dissipator 5 is located at the middle shell plane. The storage batteries 6 are symmetrically arranged on two sides of the heat dissipator 5 respectively. A gravitational center of the body care device is balanced. When the body care device is worn on the human body through the wearing strap assembly, the gravitational center of the body care device is prevented from being deviated, and the user may feel comfortable.
