[0003] The existing coffee powder loosening device directly rotates the needle disc manually after being erected on the coffee powder bowl to stir the coffee powder with the stirring needle. This method requires the hand to overcome a certain resistance and needs to rotate the needle disc for a long time to stir, which consumes hand strength and is not uniform in stirring speed, and the loosening effect is poor.

[0012] 1. The relative lifting movement between the body and the support is limited by the stroke limiting structure and the vertical guide structure and can be protected within a limited range. The relative position of the body and the support is kept at the lowest position of the body relative to the support in the normal state.

[0013] 2. The power member and the induction switch are arranged to form an induction start and stop mode. In this mode, the body only needs to be operated by the hand to complete the operation from the table top to the powder bowl, without the need for manual rotation and uniform powder loosening. The utility model is very convenient to use and is very suitable for the habits of users.

[0014] According to some embodiments of the present utility model, the lowest position of the support relative to the body is set as the initial position, a position of the support relative to the body higher than the lowest position is set as the working position, and the relative position is set as the initial position;

[0073] Referring to Figures 1-8 , the first aspect of the present application provides an inductive driving assembly, comprising:

[0074] The body 300 is connected to the support 100 in a lifting manner;

[0075] The vertical guide structure is arranged between the body 300 and the support 100, and is used to limit the relative lifting movement between the body 300 and the support 100;

[0076] The stroke limiting structure is arranged between the body 300 and the support 100, and is used to limit the stroke of the relative lifting movement between the body 300 and the support 100;

[0077] The power member is installed on the body 300;

[0078] The inductive switch is connected to the power member, and is used to induct the body 300 to reach a set relative position between the body 300 and the support 100 and control the start and stop of the power member.

[0079] The first aspect of the present application has at least the following beneficial effects:

[0080] 1. The stroke limiting structure and the vertical guide structure are used to limit the relative lifting movement between the body 300 and the support 100 and can be protected within a limited range, and the relative position between the body 300 and the support 100 is kept at the lowest position of the body 300 relative to the support 100 in the normal state by cooperating with the thimble 420;

[0081] 2. The power element and the induction switch are set to form the mode of induction start-stop power element. In this mode, the user only needs to operate the main body 300 to complete the process from the table top to the powder bowl. The user does not need to rotate the main body and the powder can be evenly loosened. The use is very convenient and very suitable for the user's habits.

[0082] Referring to Figure 2 and Figure 3 , the position of the induction switch in Figure 5 is raised Figure 3 to correspond to the position of the magnet, the extension of the basic embodiment, setting the lowest position of the bracket relative to the main body as the initial position, setting a position of the bracket relative to the main body higher than the lowest position as the working position, and setting the relative position as the working position;

[0083] The bracket and the main body are located at the initial position and are out of the induction range of the induction switch. The induction switch controls the power element to stop.

[0084] The bracket and the main body are located at the working position. The induction switch controls the power element to start.

[0085] The induction driving assembly adopts the initial position out of the induction range of the induction switch and controls the power element to stop. The relative lifting of the bracket and the main body reaches the set relative position and enters the induction range. The induction switch controls the power element to start. In this mode, the induction control of the power element can be realized.

[0086] Referring to Figures 1-6 , the extension of the basic embodiment, setting the lowest position of the bracket 100 relative to the main body 300 as the initial position, setting a position of the bracket 100 relative to the main body 300 higher than the lowest position as the working position, and setting the relative position as the initial position;

[0087] The bracket 100 and the main body 300 are located at the initial position. The induction switch controls the power element to stop.

[0088] The bracket 100 and the main body 300 are located at the working position and are out of the induction range of the induction switch. The induction switch controls the power element to start.

[0089] The initial position induction switch of the induction driving assembly can sense the set relative position between the body 300 and the support 100 and control the power member to stop. When the relative lifting of the support 100 and the body 300 is away from the set relative position and is away from the induction range, the induction switch controls the power member to start. This setting takes into account that there are various types of powder bowls in the coffee appliance industry, and the depths of different types of powder bowls are different, which leads to different relative lifting strokes of the support 100 and the body 300 for different depth powder bowls. Through this setting, only the initial position of the induction switch needs to be sensed. The powder bowls of various types are in a closed state at the initial position, and can be opened by moving away from the initial position. The working position of the powder bowls of different types does not need to be considered. This facilitates the stable use of the powder mill in different types of powder bowls. In this mode, the powder bowls of various types are at the same initial position, and the induction switch only needs to set an induction range for the initial position to be used stably. This also significantly reduces the setting requirements of the induction range of the induction switch.

[0106] It can be understood that the annular slider 110 can be provided with a mounting hole or a mounting groove corresponding to the shape of the magnet 520, facilitating the installation of the magnet 520. The annular slider 110 can be made of a metal material that can be attracted by the magnet 520, so that the magnet 520 is more stable in installation.

[0107] It can be understood that the sensing switch can also use other common corresponding switches, specifically, a contact type sensing switch, in which the sensing block contacts the sensing piece in the initial position, the body and the support are lifted relative to each other, and the sensing block is away from the sensing piece. This mode can also complete the required function.
