Abstract
Description
Technical Field
[0001] This invention relates to a clip adsorption sensing device, specifically a food clip adsorption sensing device. Background Technology
[0002] Seasoning containers containing large pieces of spices such as star anise, chili peppers, and rock sugar are often left open, causing the spices to become damp. If an electric seasoning container is used, the food clips must be placed inside, often becoming buried in the spices. Furthermore, each time the lid is opened or closed, a button needs to be pressed, and the food clips sometimes obstruct the lid from closing. Therefore, this invention provides a food clip adsorption sensing device that allows the food clip to adhere to the surface of a casing, generating a signal that replaces the traditional switch button signal whether the food clip is adsorbed onto or away from the casing. Summary of the Invention
[0003] This invention provides a food clip adsorption sensing device that allows food clips to be adsorbed onto the surface of a housing. Whether the food clip is adsorbed onto or away from the housing, it can generate a signal that replaces the traditional switch box button.
[0004] This invention provides a food clip adsorption sensing device, including a food clip, a soft magnetic material, a housing, and a Hall sensor. A magnet is installed on the food clip plate, the soft magnetic material is fixedly installed on the housing, and the Hall sensor is fixedly installed adjacent to the soft magnetic material. The food clip is adsorbed onto the housing by the magnet on the food clip plate and the soft magnetic material.
[0005] Furthermore, the food clamp plate is provided with a clamp plate groove, and the magnet is fixedly installed inside the clamp plate groove.
[0006] Furthermore, the outer shell is provided with a shell groove, and the soft magnetic material is fixedly installed inside the shell groove.
[0007] Furthermore, the soft magnetic material is silicon steel sheet.
[0008] Furthermore, the outer casing is provided with a casing groove, and a soft magnetic material is fixedly installed in the casing groove, with the Hall sensor covering the soft magnetic material; the rear cover of the outer casing is fixed at the opening of the casing groove to press the Hall sensor tightly.
[0009] Furthermore, the food clamping plate is provided with a clamping plate groove, and the magnet is fixedly installed in the clamping plate groove; the magnet cover is fixed at the opening of the clamping plate groove to press the magnet tightly.
[0010] The beneficial effects of this invention are that the food clip can be adsorbed onto the surface of the outer shell, and when the food clip is adsorbed onto the outer shell or away from the outer shell, it can generate an electrical signal that replaces the traditional switch box button signal, thereby easily controlling the opening and closing of the condiment box.

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below. Obviously, the described embodiments are only a part of the present invention, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0015] like Figure 1 As shown, a food clamp adsorption sensing device includes a food clamp 1, a soft magnetic material 7, a housing 5, and a Hall sensor 8. A magnet 3 is installed on the food clamp plate 10. The food clamp 1 and the food clamp plate 10 are an integral unit. The magnet 3 is fixedly installed on the food clamp plate 10 by at least one process, namely adhesive or injection molding.
[0016] The soft magnetic material 7 is fixedly installed on the housing 5 by at least one of the following methods: adhesive, injection molding, pressing, slotting or bolting.
[0017] The Hall sensor 8 is fixedly mounted in proximity to the soft magnetic material 7. "Proximity" includes both "close to" and "slightly away from".
[0018] The food clip 1 is attached to the outer shell 5 by the magnet on the food clip plate 10 and the soft magnetic material 7.
[0019] The food clip 1 and the food clip plate 10 are an integral unit. A magnet 3 is installed on the food clip plate 10. The magnet 3 has two functions: function 1: it has an adsorption effect on the soft magnetic material 7, which can make the food clip 1 adsorb onto the surface of the outer shell 5; function 2: the movement of the magnet 3 away from or towards the Hall sensor 8 causes the Hall sensor 8 to generate a corresponding electrical signal.
[0020] Furthermore, the food clamping plate 10 is provided with a clamping plate groove 2, and the magnet 3 is fixedly installed inside the clamping plate groove 2.
[0021] The food clamping plate 10 is provided with a clamping plate groove 2. The shape of the clamping plate groove 2 matches the shape of the magnet 3. The magnet 3 is fixedly installed inside the clamping plate groove 2 by at least one of adhesive or injection molding.

[0024] Furthermore, the soft magnetic material 7 is a silicon steel sheet.
[0025] The inventors discovered that silicon steel sheets are easier to process than other soft magnetic materials, so they chose silicon steel sheets as the soft magnetic material 7.
[0026] Furthermore, the outer shell 5 is provided with a shell groove 6, the soft magnetic material 7 is fixedly installed in the shell groove 6, and the Hall sensor 8 is covered on the soft magnetic material 7; the back cover 9 of the outer shell is fixed at the opening of the shell groove 6 to press the Hall sensor 8 tightly.
[0027] The outer shell 5 is provided with an outer shell groove 6, the shape of which matches the soft magnetic material 7. The soft magnetic material 7 is pressed and fixed in the outer shell groove 6 by a Hall sensor 8, which covers the soft magnetic material 7. The outer shell back cover 9 is fixed to the opening of the outer shell groove 6 by at least one of adhesive or bolts, pressing the Hall sensor 8 and the soft magnetic material 7 together.
[0028] Furthermore, the food clamping plate 10 is provided with a clamping plate groove 2, and the magnet 3 is fixedly installed in the clamping plate groove 2; the magnet cover 4 is fixed at the opening of the clamping plate groove 2 to press the magnet 3 tightly.
