[0001] The present application relates to the technical field of household appliance accessories, and in particular to an anti-slip stainless steel knob for a stove. Background Art

[0002] At present, most household stoves use physical knobs for control. In order to improve the aesthetics, the knobs are mostly made relatively round, especially for knobs made of stainless steel. When the user's hands are stained with highly slippery substances such as oil, the contact friction coefficient is reduced and the knob is easy to slip when holding, making it inconvenient to open, close and adjust the heat. Summary of the invention

[0003] The purpose of the present application is to provide a stainless steel knob for a stove with better anti-slip effect.

[0004] To achieve the above objectives, the present application provides an anti-slip stainless steel knob for stoves: comprising a knob body, a finger sink groove is provided on the side of the knob body, the finger sink groove extends to the upper surface of the knob body, a friction strip is provided on the edge of the top surface of the knob body and is located outside the finger sink groove, an axial hole is provided on the bottom surface of the knob body, a key groove is provided on the inner wall of the axial hole, and the key groove extends to the bottom surface of the knob body, so as to facilitate the connection with the igniter cam on the upper surface of the stove seat.

[0005] As a preferred embodiment, there is a pair of finger sinks, and the two finger sinks are symmetrically distributed, so that there is a good force-bearing surface when the knob is turned forward or reversely.

[0006] As a preferred embodiment, the maximum circumferential angle occupied by the two finger grooves on the upper surface of the knob body is less than or equal to 180°, and the friction strip occupies the other 180°.

[0007] Preferably, the upper surface of the knob body is further provided with a direction mark away from the friction strip, the direction mark is located between the two finger sinks, and the direction mark extends radially along the circle of the upper surface of the knob body, that is, the two finger sinks are symmetrical about the direction mark.

[0021] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0024] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0025] like Figure 1-5 The anti-slip stainless steel knob for stoves shown includes a short cylindrical knob body 2, which is made of stainless steel. A finger sink groove 202 is opened on the side of the knob body 2 to facilitate the insertion of fingers. The fingers here are mostly thumbs and index fingers, which are good stress-bearing areas of the knob body 2. The finger sink groove 202 extends to the upper surface of the knob body 2, and the fingers can be inserted into the finger sink groove 202 from the top of the knob body 2 without obstruction, which makes insertion more convenient. There is usually a pair of finger sink grooves 202, and the two finger sink grooves 202 are symmetrically distributed. When the knob body 2 is in a closed state, it is actually symmetrical on the left and right, so that both hands can hold the stainless steel knob more conveniently, and the front ends of the two finger sink grooves 202 are closer, and the maximum circumferential angle occupied by the two finger sink grooves 202 on the upper surface of the knob body 2 is less than or equal to 180°, that is, the upper surface area of ​​the knob body 2 occupied by the two finger sink grooves 202 will not exceed half a circle.

[0026] The top edge of the knob body 2 is provided with a friction strip 1 located outside the finger sink groove 202. The friction strip 1 is usually made of rubber or silicone material with a high surface friction coefficient to increase the friction between the knob body 2 and the hand. At the same time, since the rubber and silicone materials are soft and elastic, they are more comfortable when in contact with the hand. The upper surface edge of the knob body 2 is provided with a configuration groove 203 located between the two finger sink grooves 202. In this embodiment, the two ends of the configuration groove 203 extend to the inner walls of the two finger sink grooves 202 respectively. The friction strip 1 is fixedly connected to the configuration groove 203, generally connected by high-temperature resistant curing glue. The end face of the friction strip 1 located in the configuration groove 203 is just flush with the inner wall of the finger sink groove 202. The outer side surface of the knob body 2 is provided with a friction groove 204 located outside the finger sink groove 202. There are several friction grooves 204, all of which are longitudinally and evenly arranged. The friction grooves 204 are located below the friction strip 1 to increase the friction when the hand holds the outer side surface of the knob body 2.

[0027] The upper surface of the knob body 2 is also provided with a direction mark 201 away from the friction strip 1. The direction mark 201 is usually made of fluorescent plastic and can be clearly seen even in a dark environment. It is used to indicate the state of the knob body 2. The direction of the direction mark 201 can be used to determine whether the knob body 2 is open or closed. The direction mark 201 is located between the two finger grooves 202. Normally, when the knob body 2 is in the closed state, it points straight ahead. In this embodiment, the direction mark 201 is raised from the upper surface of the knob body 2, so that the direction mark 201 will be more obvious when it is illuminated. Of course, it can also be embedded in the knob body 2 and flush with the upper surface of the knob body 2. Although the brightness will decrease in this way, it is more convenient to wipe and clean the knob body 2. The two settings have their own advantages and disadvantages, and can be fine-tuned according to actual needs.

[0028] An axial hole 205 is provided on the bottom surface of the knob body 2 for plugging with the protruding shaft on the upper surface of the stove base. The knob body 2 is fixedly connected with a permanent magnet 3 on the inner top surface of the axial hole 205, so that the entire knob can be adsorbed on the protruding shaft above the stove base. The stability of the knob can be well maintained without interference fit, and the disassembly and assembly operation can be easily performed, so it is convenient to wipe and clean the knob. A key slot 206 is provided on the inner wall of the axial hole 205, which fits with the limit key on the side of the protruding shaft, so that the protruding shaft can receive the torsional force of the knob. The key slot 206 extends to the bottom surface of the knob body 2, so that the limit piece on the side of the protruding shaft can slide into from the bottom surface of the knob body 2. A load-reducing groove 207 surrounding the axial hole 205 and the key slot 206 is also provided on the bottom surface of the knob body 2. Because the torsional force that the knob body 2 needs to withstand is not very large, while maintaining the structural strength, consumables and weight are reduced as much as possible to pursue better lightweight.

[0029] Working principle: Before use, first insert the shaft hole 205 and key slot 206 at the bottom of the knob into the protruding shaft on the upper surface of the stove until the top of the protruding shaft contacts the permanent magnet 3 and is firmly adsorbed. At this time, the entire stainless steel knob can maintain good installation stability. When using, take the right hand as an example, when you need to turn on the stove, place the right index finger on the right finger sink groove 202, and the right thumb on the friction strip 1 or the outside of the friction groove 204. Press lightly with the palm downward and then rotate counterclockwise to ignite the stove; when you need to turn off the stove, place the right index finger on the left finger sink groove 202. , the right hand is placed on the friction strip 1 or the friction groove 204, and the stove can be turned off by rotating the palm clockwise to the initial position of the direction indicator 201 without applying pressure. The left hand operation is the same, because during the rotation process, the index finger is located in the finger sink 202, and the knob is subjected to torque by applying pressure from the side. When applying force, it is more stable than directly using the friction between the hand and the outer side of the knob. In addition, the structures such as the friction strip 1 and the friction groove 204 that directly contact the user's hand retain and enhance the contact friction between the hand and the outer side of the knob, thereby effectively suppressing the occurrence of slipping.

[0030] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought.
