When the herbaceous plant grinding machine is used, the grinding element independently rotates on the inner side of the shell through the elastic element and the elastic element container, the elastic element can halve force needed by grinding rotation, and compared with a traditional manual herbaceous plant grinding machine receiving the same force, the herbaceous plant grinding machine can generate more rotation. Besides, the upper circular plate is detachably connected with the elastic element container, and the lower circular plate is detachably connected with the shell, so that the two components forming the grinding chamber are mutually fastened, and sufficient grinding can be realized without applying pressure by a user. The problems that an existing herbaceous plant grinding machine is strenuous and inconvenient to operate are solved.

Description

Technical Field

[0001] The utility model relates to a semi-automatic device for grinding herbs and similar products. Background Art

[0002] A device for grinding herbs and similar products, hereinafter referred to as an herb grinder, is a device consisting of at least two separate parts which, once connected, form a space called a grinding chamber. Both parts are equipped with suitable grinding elements which, due to their rotational movement, grind the herbs contained therein into uniform small pieces for consumption. Hitherto, in order to effectively use the device, it was necessary to place the herbs between the two parts equipped with grinding elements and then connect the two parts to form the grinding chamber.

[0003] Then, use one hand to stabilize the bottom of the herb grinder while using the other hand to rotate the rest of the section that makes up the grinding chamber and repeat the clockwise and counterclockwise motions while applying continuous pressure from the top to the bottom to hold the two sections together in order to grind the herb.

[0004] If some resistance occurs, more force needs to be applied both to the rotational movement and to hold the two parts together. The parts that make up the grinding chamber need to be rotated until the resistance created by the herb disappears, which is a clear sign that the herb has been ground.

[0005] Manual herb grinders sold to date have several disadvantages including: 1) the need to apply constant force to initiate and maintain the rotation of the two parts of the grinding chamber; and 2) the need to apply constant pressure between the two parts that make up the grinding chamber to keep them tight to grind the herb. Utility Model Content

[0006] The technical problem to be solved by the present invention is to avoid the above-mentioned deficiencies of the prior art and provide a semi-automatic device for grinding herbs and similar products, which can save the force required to keep the two parts of the grinding chamber rotating and avoid applying pressure on the parts constituting the grinding chamber, thereby making the grinding of herbs and similar products more labor-saving and easier to operate.

[0007] The technical solution adopted by the utility model to solve the technical problem is:

[0008] 1) An elastic element, under the action of an external force, produces significant elastic deformation and stores the work done by the force as elastic potential energy. The elastic element can complete the same number of reverse rotations without using any energy from the user, and can simply return to its previous shape. This means that the elastic element can halve the force required to grind the herb. In a preferred embodiment, the elastic element is a spiral spring, and can also be a torsion spring, a helical extension spring, an elastic band, a helical compression spring, etc.

[0009] 2) The grinding chamber is composed of parts held together by releasable coupling means, which ensures the fastening between the parts even during its use without the need for pressure from the user. In a preferred embodiment, the releasable coupling means is composed of a threaded element, but may also be a latch, a buckle, a spring pin, a spring clip, a magnetic sheet, etc.

[0010] 3) The device is also characterized in that the grinding element (specifically the upper grinding element) is not a whole with the housing in which it is installed, but rotates independently in the housing through the elastic element and the elastic element container. When the elastic element returns to its initial position without the user applying force, the grinding element is also returned together, so that the grinding element can make full use of the elastic potential energy of the elastic element, thereby optimizing the force applied to the grinding element. In addition, suitable tools can be applied to the elastic element container to reduce the friction generated when the elastic element container rotates, while making it smoother and more stable. In a preferred embodiment, the tool is composed of various types of bearings, such as ball bearings, cylindrical roller bearings, tapered roller bearings and needle bearings.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1) The force required to rotate the components of the grinding chamber is halved; 2) No pressure is required on the components constituting the grinding chamber; 3) More rotations can be generated compared to a conventional manual herb grinder that receives the same force. The utility model disclosed in the present application makes the grinding of herbs and similar products more labor-saving and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The primary container 8 is used to collect the herbs and similar products ground by the grinding chamber, and the herbs and similar products are filtered when passing through the filter holes 7b below the grinding chamber. The primary container 8 is also equipped with a filter screen 8a for secondary filtering of the herbs and similar products.

In a preferred embodiment, the traction element is a cable, and can also be a traction element such as a pull rod, a chain, or a traction belt.

[0029] The working principle of the utility model is:

[0030] 1) When the user pulls the pulling element 10, the pulling element 10 passes through the housing 1 through the hole 1b, and pulls the elastic element 4 through the other end 4a of the elastic element 4 exposed from the side window 2a. The elastic element 4 independently rotates around the central pivot 1a inside the housing 1 and drives the elastic element container 2 to rotate through the side window 2a. The elastic element container 2 is detachably connected to the upper circular plate 5 and drives the upper grinding element 5a for chopping herbs to rotate. At the same time, since the lower circular plate 7 is detachably connected to the housing 1, and the upper grinding element 5a and the lower grinding element 7a are staggered up and down, a relative rotational motion can be formed to grind the herbs.

[0031] 2) When the user releases the pulling element 10, the elastic potential energy of the elastic element 4 restores the elastic element container 2 and the upper circular plate 5 connected to the elastic element container 2 to the initial position through the side window 2a, thereby forming a rotational movement in the opposite direction, so that grinding can be performed again without the user applying force. This means that the force required to rotate the grinding chamber component is halved, and more rotation can be generated compared to a traditional manual herb grinder that receives the same force.

[0032] 3) During the above operation, the grinding chamber consisting of the upper and lower parts is held tight by the upper circular plate 5 being detachably connected to the elastic element container 2 and the lower circular plate 7 being detachably connected to the housing 1. This means that the user can fully grind herbs and similar products without applying pressure to the parts constituting the grinding chamber.

[0033] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above are only preferred implementations of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
