[0001] The present application belongs to the technical field of baking utensils, and particularly relates to a cake smearing tool for smearing cream or other coatings on the surface of a cake. BACKGROUND

[0002] In the process of making a cake, the cake is usually placed on a rotatable turntable, and a spatula is used to evenly smear and smoothen cream or other coatings on the surface of the cake.

[0003] The cake spatula on the market at present is mostly of an integrated structure and has a fixed size and shape of the blade. Such a structure of the spatula has obvious defects: firstly, for cakes of different heights, diameters and even special shapes (such as arc-shaped sides), the operator needs to prepare a plurality of different specifications and shapes of spatulas to meet the requirements, which is poor in versatility, increases cost and is inconvenient to use; secondly, the fixed size and shape are difficult to accurately adapt to diversified cake profiles, and the adjustment process relies on experience and visual observation, which leads to low efficiency and insufficient accuracy and easily causes uneven smearing of the coatings. SUMMARY

[0004] The present application aims to overcome the defects of the prior art that the size and shape of the cake spatula are fixed, the adjustment accuracy is low, and the spatula is single in adapting to the shape of the cake.

DETAILED DESCRIPTION

[0017] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0019] like Figure 1 - Figure 5 As shown, an adjustable cake smoothing knife of the present invention includes a first ruler plate 1, a second ruler plate 2 and at least one set of detachable fastening components 5. One or more elongated through holes 3 are provided along the length of both the first ruler 1 and the second ruler 2. The first ruler 1 and the second ruler 2 are connected by fastening components 5 passing through their respective elongated through holes 3, and can be assembled into a structure that is perpendicular to each other. By adjusting the tightness of the fastening component 5, the first ruler plate 1 and the second ruler plate 2 can slide relative to each other and be fixed along their respective elongated through holes 3, thereby achieving continuous adjustment of the overall size of the smoothing knife.

[0020] Specifically, the first ruler plate 1 is a horizontal scraper with a straight blade edge or an arc-shaped blade edge adapted to the top / side of the cake, used to smooth the top / side edges of the cake. The second plate, 2, is a vertical plate with a straight or curved cutting edge, used to smooth the top / side of the cake.

[0021] Once assembled, the working edges of the two boards together form an "L", "+", or "T" shaped working area that can be adjusted according to the size and shape of the cake.

[0022] With the design of the elongated through-hole 3 and the fastening component 5, users can make stepless adjustments according to the actual size of the cake, which has high flexibility and wide adaptability.

[0023] The first plate 1 and the second plate 2 in this technical solution are made of food-grade stainless steel or environmentally friendly materials.

[0024] like Figure 4 As shown, the lengths of the first ruler 1 and the second ruler 2 may be the same or different to accommodate different cake size adjustment needs.

[0025] like Figure 1 , Figure 4 As shown, the first ruler plate 1 and / or the second ruler plate 2 are ruler-shaped or fan-shaped.

[0026] Specifically, the first ruler plate 1 and the second ruler plate 2 are both ruler-shaped stainless steel plates of equal length. They are connected by fastening assembly 5 to form a mutually perpendicular "+" shape.

[0027] This embodiment is suitable for smoothing most right-angled cylindrical cakes, and the work area can be precisely adjusted to the desired diameter and height using the scale.

[0028] When the first ruler 1 and / or the second ruler 2 are fan-shaped, their working edges are straight cutting edges or arc-shaped cutting edges that are consistent with the outer edge of the fan shape.

[0029] like Figure 3 As shown, the first ruler plate 1 is a relatively long straight ruler plate, and the second ruler plate 2 is a fan-shaped plate (e.g., a fan with a 90° central angle). The working edges of both are straight cutting edges and / or curved cutting edges.

[0030] If the working edge is fan-shaped (not shown in the illustration), the shape of the cake's side or top should conform to the spatula ruler.

[0031] Of course, the working edges of the first ruler 1 and / or the second ruler 2 can also be other shapes, such as wavy, triangular or other irregular structures, without specific restrictions.

[0032] When the two are assembled vertically, they form a "T"-shaped structure. In this embodiment, the fan-shaped ruler is easier for the operator to grip compared to the straight ruler.

[0033] like Figure 4 , Figure 5 As shown, both the first ruler 1 and the second ruler 2 are ruler-shaped, but the first ruler 1 is significantly longer than the second ruler 2. This combination is suitable for cakes with a large diameter but a short height, as the longer ruler provides sufficient horizontal scraping span, while the shorter ruler is used to handle the top edge. Similarly, when the first ruler 1 is shorter than the second ruler 2, this combination is suitable for cakes with a small diameter but a tall height.

[0034] The first ruler 1 and the second ruler 2 can be of the same or different lengths, and can be combined in different shapes such as straight rulers or fan-shaped rulers (for example, two straight rulers can be combined for regular right-angle cakes; a straight ruler and a fan-shaped ruler can be combined to make cakes with prominent curved sides).

[0035] This modular design approach greatly expands the applicability of single tools, enabling "one tool for multiple uses" and significantly reducing the cost for users to purchase and manage multiple specialized tools.

[0036] Users can choose the appropriate size board to combine and adjust according to the shape characteristics of the target cake, making it highly versatile.

[0037] Furthermore, even if an adjustable design exists, stress concentration is likely to occur at both ends of the adjustment slide (such as a regular strip hole). After long-term repeated adjustment and stress, there may be a risk of cracking. Moreover, there is room for improvement in the smoothness of adjustment and the stability of locking.

[0038] In this embodiment, the elongated through-hole 3 is preferably a racetrack-shaped through-hole or a racetrack-like through-hole.

[0039] The racetrack-shaped through-hole can effectively disperse stress, reduce the risk of fatigue cracking, extend the service life of the trowel, and provide stable sliding guidance.

[0040] In addition, the first ruler plate 1 and the second ruler plate 2 are provided with scale markings 4 for indicating the adjustment amount; The scale marking 4 can directly indicate the unit of measurement, or related information such as the recommended values ​​for cake diameter and height.

[0041] Specifically, the scale markings 4 are arranged along one or both sides of the elongated through hole 3.

[0042] The added scale marking 4 transforms the adjustment process from relying on experience and visual estimation to a quantitative and precise operation, greatly improving adjustment efficiency and consistency. Especially when combining different shaped rulers, the scale helps to accurately set key dimensions. The adjustment mechanism is intuitive and simple, and combined with the scale reference, it lowers the operating threshold.

[0043] Common spatulas have relatively simple blade treatments, which can easily scratch the soft cake base or the applied butter coating during the smoothing process, affecting the surface smoothness of the finished product. They are also difficult to clean and pose hygiene risks.

[0044] In this embodiment, the first ruler 1 and the second ruler 2 have undergone surface smoothing treatment on their working edges.

[0045] Surface smoothing treatment specifically includes polishing or rounding.

[0046] Polishing or rounding the edges of the workpiece can greatly reduce frictional resistance, making the smoothing process smoother and more fluid, effectively preventing scratches on the cake or tears in the cream layer, thus obtaining a smooth and clean cake surface.

[0047] The smooth surface makes it less likely for cream residue to adhere, greatly facilitating cleaning and improving the hygiene of the tool.

[0048] In this embodiment, the fastening component 5 specifically includes a bolt 50 and a nut 51 that mates with it.

[0049] The fastening component 5 in the embodiments is not limited to the described situation, and there may be other alternatives.

[0050] It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
