[0026] Please refer to Figure 1-5A detachable charging structure of a handheld blender includes a battery 102 pack assembly 1, which is detachably mounted on a blender body 2. The battery 102 pack assembly 1 includes a shell 101, a battery 102 disposed inside the shell 101 and electrically connected, and a PCBA board 103, wherein the shell 101 is composed of two upper and lower plastic shells 101 snapped together, the number of batteries 102 is two and they are rechargeable batteries 102, and the PCBA board 103 is integrated with multiple units, including a charging interface 110 and a safety unit, etc. The charging interface 110 is one or a combination of a USB interface or a TYPE-C interface. In this embodiment, a TYPE-C interface is used, and a user can charge the battery 102 through the TYPE-C interface. The safety unit is a delayed power-on unit, that is, after the safety unit is triggered, a current signal will be transmitted to the blender body 2 within 5 seconds, so that the blender body 2 needs a period of time before it can work normally, thereby improving the safety factor of the blender. This safety unit is a prior art and will not be described in detail in this application.

[0027] A connector 104 is provided at the bottom of the shell 101. The connector 104 and the lower shell 101 are an integrated structure. Through integral injection molding, guide members 105 are provided on both sides of the connector 104. A connecting cavity 201 adapted to the connector 104 is provided at the top of the agitator body 2. Guide grooves 202 adapted to the guide member 105 are provided on both sides of the connecting cavity 201. The connector 104 can be assembled into the connecting cavity 201, and the guide member 105 can be assembled into the guide groove 202. That is, the battery 102 pack assembly 1 is used in conjunction with the connector 104, the guide member 105, the connecting cavity 201, and the guide groove 202. The blender body 2 achieves the purpose of detachable connection; the battery 102 package component 1 also includes a female terminal 108, which is arranged at one end of the connecting piece 104 and is electrically connected to the PCBA board 103. The blender body 2 is provided with a male terminal 204 that is compatible with the female terminal 108. The male terminal 204 is arranged in the connecting cavity 201. The male terminal 204 and the female terminal 108 are used in coordination. When the connecting piece 104 is assembled in the connecting cavity 201, the male terminal 204 and the female terminal 108 are connected and conductive, so that the electric energy of the battery 102 can be transmitted to the blender body 2, thereby providing electric energy for the operation of the blender body 2.

[0028] In order to enable the battery 102 package assembly 1 to be fixed on the blender body 2, a slot 106 is provided at the bottom of the connecting piece 104, and an inner side wall of the slot 106 is an arc wall 107. The depth of the slot 106 gradually becomes shallower from one end close to the arc wall 107 to the other end. A snap connector 203 adapted to the slot 106 is provided in the connecting cavity 201. The snap connector 203 is a plastic part and only one side is connected to the blender body 2. The side of the snap connector 203 connected to the blender body 2 is slightly tilted toward the other side and is elastic. When the connecting piece 104 is fully assembled in the connecting cavity 201, the snap connector 203 will be snapped into the slot 106 to fix the battery 102 package assembly 1. The design of the arc wall 107 will facilitate the snap connector 203 to enter or leave the slot 106.

[0029] Both the male terminal 204 and the female terminal 108 have a 10-pin structure, with four positive and four negative pins and two signal lines.

[0030] A micro switch, a control switch, a drive motor, a stirring blade, etc. are arranged inside the agitator body 2. The micro switch is electrically connected to the male terminal 204, the drive motor is electrically connected to the micro switch, and the stirring blade is connected to the drive shaft of the drive motor. This agitator body 2 is a prior art and will not be described in detail in this application.

[0031] The battery 102 package assembly 1 further includes a safety switch 109 , which is disposed on the housing 101 , and the safety switch 109 can trigger a safety unit.

[0032] The battery 102 package assembly 1 also includes a plurality of pairs of mounting frames 111, which are disposed in the housing 101 and are used to fix the battery 102 and the PCBA board 103. The mounting frames 111 are provided with mounting cavities 112 and hooks 113. The ends of the batteries 102 are mounted in the mounting cavities 112, and the PCBA board 103 is mounted on the mounting frames 111 and fixed by the hooks 113.

[0033] The utility model is a detachable charging structure for a handheld blender, and its working principle is explained in conjunction with the accompanying drawings in the specification:

[0034] The battery pack assembly 102 can be removed separately and charged using a power cord and a charging interface 110 .

[0035] When in use, align the connector, guide member 105 with the connecting cavity 201 and guide slot 202, slide the battery 102 package assembly 1 into the connecting cavity 201, and fix it by the cooperation of the snap connector 203 and the slot 106, press the safety switch 109, and the current signal will be transmitted to the blender body 2 within 5 seconds. Then press the control switch, the micro switch is connected to the circuit, and the drive motor works to drive the blender blade to rotate, so that the food is blended.

[0036] When the battery 102 pack assembly 1 needs to be charged, the battery 102 pack assembly 1 only needs to be slid, and the arc wall 107 will give a downward pressure to the clamping part 203, causing the clamping part 203 to rotate and disengage from the card slot 106. The battery 102 pack assembly 1 can be removed from the connecting cavity 201 for charging. The battery 102 pack assembly 1 provides power to the blender body 2 through the matching wiring terminals, and the traditional wired handheld blender is changed to a wireless structure, so that the use scenario of the blender is no longer limited, and it can be used in an environment without a power socket; and the power cord is abandoned, giving the user a better user experience.
