Description

Technical Field

[0001] The present application relates to the technical field of daily necessities, and in particular to a stirring rod and a stirrer. Background Art

[0002] Milk powder is one of the main foods for infants and young children. Before feeding milk powder to infants and young children, the milk powder needs to be fully brewed and dissolved in warm boiled water. The usual way to brew milk powder is to put the milk powder into a bottle and pour in warm boiled water to dissolve it. The temperature of warm boiled water should be 40-60℃. Higher temperature will destroy the nutritional components of milk powder, and some components cannot be dissolved below this temperature. Generally speaking, since milk powder is not easily soluble in water, the milk powder cannot be fully dissolved after pouring into warm boiled water. Manual shaking has problems of uneven shaking speed and unstable shaking direction, which can easily cause more bubbles in the bottle. If the baby inhales too many bubbles, it can easily cause stomach bloating and milk regurgitation, affecting the feeding effect. Utility Model Content

[0003] Based on this, it is necessary to provide a stirring rod and a stirrer to address the problem of bubbles that are easily generated in the prepared milk powder.

[0004] A stirring rod of the present application, the stirring rod comprising:

[0005] A rod body, the rod body being drivingly connected to the driving motor;

[0006] A paddle, wherein the number of the paddles is two, and the two paddles are connected to an end of the rod body away from the driving motor;

[0007] The blades include a water-facing surface, a water-receiving surface and a blade tip connected to each other in pairs, wherein the water-facing surface of one blade and the water-receiving surface of another blade form a water-receiving groove;

[0008] The water-facing surface comprises an upper facing surface and a lower facing surface, wherein the upper facing surface is connected to the lower facing surface and forms a continuous curved surface, the upper facing surface is an inclined curved surface, and the two upper facing surfaces are distributed in a spiral shape with the axis of the rod body as the center.

[0009] The stirring rod disclosed in the first aspect of the present application includes a rod body and two paddles connected to the rod body. The rod body can be connected to the driving motor in a transmission manner. The paddles are at least composed of a water-facing surface, a water-receiving surface and a blade tip that are interconnected in pairs. After the driving motor rotates, the paddles rotate with the rod body. The lower water-facing surface can guide the mixture to the upper facing surface. The upper facing surfaces of the two paddles are distributed in a spiral shape with the axis of the rod body as the center, and the upper facing surface is an inclined curved surface with the tail end of the curved surface facing the extension direction of the rod body. The upper facing surface can push the mixture to move in the extension direction of the rod body, thereby offsetting the vortex generated when the rod body rotates, thereby reducing the generation of bubbles.

[0010] In one embodiment, the two blades are arranged rotationally symmetrically.

[0011] The stirring rod in the above embodiment further defines that the two blades are arranged in rotational symmetry to improve the stability of the stirring rod during the stirring process and avoid large shaking.

[0012] In one embodiment, the blade tip is spherical and is arranged at the intersection of the water-facing surface and the water-retaining surface away from the rod body.

[0013] The stirring rod in the above embodiment further defines a spherical blade tip structure to reduce the resistance of the mixture to the blade tip and improve the flexibility of the stirring rod.

[0014] In one of the embodiments, the distance between the blade tip and the axis of the rod body increases first and then decreases from the bottom to the top of the blade tip.

[0015] The stirring rod in the above embodiment further defines that the distance between the blade tip and the axis of the rod body first increases and then decreases from the bottom of the blade tip to the top. Based on the above structure, the distance between the bottom of the blade tip and the axis of the rod body is smaller, which can reduce the resistance of the mixture at the bottom of the cup body to the bottom of the blade tip. The distance between the blade tip and the axis of the rod body increases and then shortens, so as to form an inwardly inclined angle between the top of the blade tip and the rod body, so that when the blade rotates, the mixture located at the upper face can obtain a thrust toward the direction of the rod body on the inwardly inclined structure between the top of the blade tip and the rod body, thereby avoiding the diffusion of the mixture located at the upper face and moving away from the rod body.

[0016] In one embodiment, the width of the blade tip increases first and then decreases from the bottom to the top of the blade tip.

[0017] The stirring rod in the above embodiment further defines that the width of the blade tip first increases and then decreases from the bottom of the blade tip to the top. Based on the above mechanism, the width of the bottom of the blade tip is smaller, which can reduce the resistance of the mixture at the bottom of the cup body to the bottom of the blade tip. The width of the blade tip increases and then shortens the distance between the two, so that an inclined surface is formed on the upper surface that can push the mixture to move in the extension direction of the rod body.

[0018] In one embodiment, the back-to-water surface is flat.

[0019] In one embodiment, the lower front surface is convex in the middle and concave on both sides along the height direction of the rod body.

[0020] In one embodiment, the connection between the upper front surface and the lower front surface forms a first arc segment, the first arc segment includes a first endpoint and a second endpoint, the connection between the upper front surface and the back water surface forms a second arc segment, the second arc segment includes a third endpoint and a fourth endpoint, the first endpoint and the third endpoint constitute a first straight line segment, the angle between the first straight line segment and the horizontal direction is a first angle, and the range of the first angle is 25 degrees to 55 degrees.

[0021] The stirring rod in the above embodiment further defines that a first angle between a first straight line segment formed by the first end point and the third end point and the horizontal direction is limited to 25 degrees to 55 degrees, at which time the thrust effect of the upper surface on the mixture is better.

[0022] In one embodiment, the angle between the tangent line of the third endpoint and the vertical direction is a second angle, and the range of the second angle is 45 to 80 degrees.

[0023] The stirring rod in the above embodiment further limits the third angle between the tangent of the third end point and the vertical direction to 45 degrees to 80 degrees, that is, an inwardly inclined structure is formed between the second arc segment and the rod body. When the blade rotates, this inwardly inclined structure generates a force that pushes the mixture toward the rod body.

[0024] In one embodiment, the rod is cylindrical.

[0025] The stirring rod in the above embodiment further defines that the rod body is designed to be cylindrical so as to reduce bubbles generated by the vortex of the mixture caused by the rotation of the rod body.

[0026] In one embodiment, the stirrer provided in the second aspect of the present application comprises:

[0027] A stirring rod as described in any one of the above items;

[0028] A cup body and a cup cover, wherein the cup body and the cup cover are detachably connected;

[0029] A drive motor and a battery are installed in the space formed in the cup cover, the drive motor is electrically connected to the battery, the drive motor is transmission-connected to the stirring rod, and the stirring rod is inserted into the space formed by the cup body.

[0030] The agitator provided in the second aspect of the present application, after the driving motor rotates, the blades rotate with the rod body, and the lower facing surface in the water-facing surface can guide the mixture to the upper facing surface. The upper facing surfaces based on the two blades are spirally distributed with the axis of the rod body as the center, and the upper facing surface is an inclined curved surface, and the tail end of the curved surface is toward the extension direction of the rod body. The upper facing surface can push the mixture composed of milk powder and water to move toward the extension direction of the rod body, thereby offsetting the vortex generated when the rod body rotates, reducing the generation of bubbles during the milk making process, and thus causing symptoms such as gastrointestinal bloating and indigestion.

[0041] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0042] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so as to describe the embodiments of the present application described herein.

[0043] like Figures 1 to 6 As shown, this embodiment provides a stirring rod 1, and the stirring rod 1 includes:

[0044] The rod body 20 is transmission-connected to the driving motor 4;

[0045] The paddle blade 10 is two in number, and the two paddle blades 10 are connected to one end of the rod body 20 away from the driving motor 4;

[0046] The blades 10 include a water-facing surface 11, a water-receiving surface 12 and a blade tip 13 connected to each other in pairs, wherein the water-facing surface 11 of one blade 10 and the water-receiving surface 12 of another blade 10 form a water-receiving groove 14;

[0047] The water-facing surface 11 includes an upper facing surface 111 and a lower facing surface 112 , and the upper facing surface 111 and the lower facing surface 112 are connected and continuous.

[0048] The drive motor 4 can provide power for the rod body 20 to rotate. The rotation axis of the drive motor 4 coincides with the central axis of the rod body 20, and the rotation axis of the drive motor 4 and the rod body 20 can be engaged, so that the rod body 20 can rotate synchronously with the rotation axis of the drive motor 4.

[0049] The rod body 20 may be, but is not limited to, a metal long column or a non-metal long column. For example, the rod body 20 may be a 420 stainless steel long column. The rod body 20 may be connected to the drive motor 4 in a transmission manner. Specifically, a slot is provided on one end of the rod body 20 away from the blade 10, and the slot is adapted to the rotating shaft of the drive motor 4. The rod body 20 and the drive motor 4 are connected by the friction between the rotating shaft and the side wall of the slot through the rotating shaft inserted into the slot.

[0050] The blade 10 may be, but is not limited to, a metal shell or a non-metal shell. For example, the blade 10 may be a 420 stainless steel shell. The blade 10 may rotate along with the rotation of the rod body 20. When the blade 10 rotates, the side of the blade 10 facing the water first is the water-facing surface 11, and the side opposite to the water-facing surface 11 is the water-repelling surface 12.

[0051] The lower facing surface 112 can guide the mixture to the upper facing surface 111 during the rotation of the impeller 10 .

[0052] The upper face 111 can change the movement direction of the mixture flowing through the upper face 111. For example, the upper face 111 is an inclined curved surface, the tail end of which faces the extension direction of the rod body 20, and the two upper faces 111 are distributed in a spiral shape with the axis of the rod body 20 as the center. When the blade 10 rotates, the mixture moves toward the extension direction of the rod body 20 under the push of the two upper faces 111, thereby offsetting the vortex generated when the rod body 20 rotates, thereby reducing the generation of bubbles.

[0053] The stirring rod 1 in the above embodiment includes a rod body 20 and two blades 10 connected to the rod body 20. The rod body 20 can be connected to the driving motor 4 in a transmission manner. The blades 10 are at least composed of a water-facing surface 11, a water-receiving surface 12 and a blade tip 13 that are connected to each other in pairs. After the driving motor 4 rotates, the blades 10 rotate with the rod body 20. The lower facing surface 112 in the water-facing surface 11 can guide the mixture to the upper facing surface 111. The upper facing surfaces 111 of the two blades 10 are distributed in a spiral shape with the axis of the rod body 20 as the center, and the upper facing surface 111 is an inclined curved surface with the tail end of the curved surface facing the extension direction of the rod body 20. The upper facing surface 111 can push the mixture to move in the extension direction of the rod body 20, thereby offsetting the vortex generated when the rod body 20 rotates, thereby reducing the generation of bubbles.

[0054] like Figures 1 to 3 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the two blades 10 are rotationally symmetrically arranged.

[0055] The two blades 10 are rotationally symmetrically arranged to ensure that the stirring rod 1 remains stable during the stirring process and avoids large shaking.

[0056] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the blade tip 13 is spherical, and the blade tip 13 is arranged at the intersection of the water-facing surface 11 and the water-retaining surface 12 away from the rod body 20.

[0057] The blade tip 13 is a spherical structure to reduce the resistance of the mixture to the blade tip 13 and improve the flexibility of the stirring rod. It should be noted that in other embodiments, the blade tip 13 may also be a discontinuous curved surface structure.

[0058] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the distance between the blade tip 13 and the axis of the rod body 20 increases first and then decreases from the bottom to the top of the blade tip 13.

[0059] Among them, the distance between the blade tip 13 and the axis of the rod body 20 first increases and then decreases from the bottom to the top of the blade tip 13. Based on the above structure, the distance between the bottom of the blade tip 13 and the axis of the rod body 20 is small, which can reduce the resistance of the mixture at the bottom of the cup body 2 to the bottom of the blade tip 13. The distance between the blade tip 13 and the axis of the rod body 20 increases and then shortens. The purpose is to form an inwardly inclined angle between the top of the blade tip 13 and the rod body 20, so that when the blade 10 rotates, the mixture located at the upper front surface 111 can obtain a thrust toward the rod body 20 on the inwardly inclined structure between the top of the blade tip 13 and the rod body 20, thereby avoiding the mixture located at the upper front surface 111 from diffusing and moving away from the rod body 20.

[0060] like Figures 2 to 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the width of the blade tip 13 increases first and then decreases from the bottom to the top of the blade tip 13.

[0061] Among them, the width of the blade tip 13 first increases and then decreases from the bottom to the top of the blade tip 13. Based on the above-mentioned mechanism, the width of the bottom of the blade tip 13 is smaller, which can reduce the resistance of the mixture at the bottom of the cup body 2 to the bottom of the blade tip 13. The width of the blade tip 13 increases and then shortens the distance between the two, so that the upper face 111 forms an inclined surface that can push the mixture to move in the extension direction of the rod body 20.

[0062] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment is further defined as follows: the back water surface 12 is flat.

[0063] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the lower front surface 112 is convex in the middle and concave on both sides along the height direction of the rod body 20.

[0064] like Figure 3 and Figure 4 As shown, in addition to the features of the above-mentioned embodiments, the present embodiment further defines: the connection between the upper front surface 111 and the lower front surface 112 forms a first arc segment 101, the first arc segment 101 includes a first endpoint N1 and a second endpoint N2, the connection between the upper front surface 111 and the back surface 12 forms a second arc segment 102, the second arc segment 102 includes a third endpoint N3 and a fourth endpoint N4, the first endpoint N1 and the third endpoint N3 constitute a first straight line segment, the angle between the first straight line segment and the horizontal direction is a first angle C1, and the range of the first angle C1 is 25 degrees to 55 degrees.

[0065] The first angle C1 between the first straight line segment formed by the first endpoint N1 and the third endpoint N3 and the horizontal direction is limited to 25 degrees to 55 degrees. At this time, the thrust effect of the upper face 111 on the mixture is better. Preferably, the first angle C1 is 42 degrees.

[0066] like Figure 3 and Figure 4 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the angle between the tangent line of the third endpoint N3 and the vertical direction is a second angle C2, and the range of the second angle C2 is 45 degrees to 80 degrees.

[0067] Among them, the third angle between the tangent based on the third endpoint N3 and the vertical direction is 45 degrees to 80 degrees, that is, an inwardly inclined structure is formed between the second arc segment 102 and the rod body 20. When the blade 10 rotates, this inwardly inclined structure generates a force to push the mixture toward the rod body 20.

[0068] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the rod body 20 is cylindrical.

[0069] The cylindrical design of the rod body 20 can reduce the bubbles generated by the vortex of the mixture caused by the rotation of the rod body 10. It should be noted that the shape of the rod body 20 can also be a long columnar body such as a square shape.

[0070] like Figure 5 and Figure 6 As shown, this embodiment provides a stirrer, comprising: the above-mentioned stirring rod 1, a cup body 2 and a cup cover 3, wherein the cup body 2 and the cup cover 3 are detachably connected;

[0071] The driving motor 4 and the battery 5 are installed in the space formed in the cup cover 3 , the driving motor 4 is electrically connected to the battery 5 , the driving motor 4 is transmission-connected to the stirring rod, and the stirring rod is inserted into the space formed by the cup body 2 .

[0072] The agitator in the above embodiment, after the driving motor 4 is rotated, the blades 10 rotate with the rod body 20, and the lower facing surface 112 in the water-facing surface 11 can guide the mixture to the upper facing surface 111. The upper facing surfaces 111 of the two blades 10 are spirally distributed with the axis of the rod body 20 as the center, and the upper facing surface 111 is an inclined curved surface, and the tail end of the curved surface is toward the extension direction of the rod body 20. The upper facing surface 111 can push the mixture of milk powder and water to move toward the extension direction of the rod body 20, thereby offsetting the vortex generated when the rod body 20 rotates, reducing the generation of bubbles during the milk making process, and thus causing symptoms such as gastrointestinal bloating and indigestion.

[0073] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.

[0074] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present utility model patent shall be subject to the attached claims.
