Description

TECHNICAL FIELD

[0001] The utility model relates to food machinery technical field, especially a spring shaft for frying pan. BACKGROUND

[0002] In the automatic frying pan, the driving device is connected with the scraper through the spring shaft, the spring shaft has certain elasticity, so that when the driving device drives the scraper to rotate, the scraper and the inner wall of the frying pan are in flexible contact, thereby the material in the frying pan is stirred. The structure of the spring shaft plays a key role in the service life of the scraper and the frying pan.

[0003] The existing spring shaft for frying pan has many defects to be solved. For example, the patent number CN2800818Y discloses a sauce frying pan. The scraper adopts spring elasticity scraping, which is composed of scraper head, fixed frame, pin shaft, spring shaft, fixed sleeve and spring. The fixed sleeve is provided with a guide pin, and the spring shaft has a guide groove. The fixed sleeve is welded on the stirring shaft by the support.

[0004] The above structure has the following problems:

[0005] 1. In the aspect of elastic adjustment, the above structure lacks effective adjustment mechanism. Since the pressure between the scraper and the inner wall of the frying pan has a significant influence on the turnover effect and the service life of the frying pan, the spring elasticity cannot be adjusted, so that the pressure between the scraper and the inner wall of the frying pan cannot be flexibly adjusted according to different cooking requirements, food types and wear conditions of the frying pan. During the cooking process, if the pressure between the scraper and the inner wall is too large, it will not only accelerate the wear of the scraper and the inner wall of the frying pan, but also shorten the service life. In addition, it may cause uneven turnover due to excessive friction, affecting the cooking quality. On the contrary, if the pressure is too small, the food cannot be evenly turned over, which may cause the food to stick to the pot and burn.

[0006] 2. As for the matching mode of the spring shaft extension, the keyway matching mode is adopted. This matching mode exposes the problem of serious lack of lubrication in actual application. During the frequent extension and contraction of the spring shaft, due to the lack of sufficient lubrication, dry grinding will cause the friction to increase sharply. On the one hand, this will greatly accelerate the wear of the spring shaft, reduce its mechanical properties and service life, and increase the maintenance cost and replacement frequency. On the other hand, excessive friction will consume more energy, reducing the energy utilization efficiency of the entire frying pan device.

[0007] In summary, the existing spring shaft for frying pan has the above-mentioned problems in the aspects of elastic adjustment and extension and contraction lubrication, which seriously restricts the improvement of the performance of the frying pan and the optimization of the cooking experience. Therefore, there is an urgent need for a new design of the spring shaft for frying pan which can effectively solve the above-mentioned problems. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present application more apparent and understandable, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the following description, a large number of specific details are set forth in order to provide a sufficient understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0031] Please refer to Figures 1 to 6 The embodiment of the present application provides a spring shaft for frying pans, which comprises a stirring rod 1, a shaft sleeve 2, a square guide sleeve 3, a spring seat 4, a spring 5 and a spring positioning ring 6.

[0032] The shaft sleeve 2 and the square guide sleeve 3 are coaxially arranged and detachably fixedly connected, and specifically, the shaft sleeve 2 and the square guide sleeve 3 are threadedly connected.

[0033] The spring 5, the spring positioning ring 6, the spring seat 4, the shaft sleeve 2 and the square guide sleeve 3 are all sleeved on the stirring rod 1, and the spring 5, the spring positioning ring 6 and the spring seat 4 are all located on the inner side of the shaft sleeve 2, please refer to Figure 3 and Figure 4 The spring positioning ring 6 is radially provided with two symmetrically distributed internal thread holes for mounting the screw 7, and the spring positioning ring 6 is detachably connected with the stirring rod 1 through the screw 7; one end of the spring 5 is connected with the spring positioning ring 6, the other end of the spring 5 is connected with the spring seat 4, and the end of the spring seat 4 away from the spring 5 abuts against the square guide sleeve 3; when the screw 7 is not installed, the spring positioning ring 6 can be moved axially along the stirring rod 1, the closer the spring positioning ring 6 is to the spring seat 4, the more the spring 5 is compressed, and the greater the elastic force is; after adjustment, the screw 7 is installed in the internal thread hole, so that one end of the screw 7 presses the stirring rod 1 tightly, and the fixation of the spring positioning ring 6 is realized.

[0034] The spring positioning ring 6 can flexibly adjust the spring force of the spring 5. Different food materials and cooking methods have different requirements for the pressure between the scraper and the inner wall of the wok. For example, when cooking fragile food materials such as tender leaf vegetables, a smaller pressure is required to prevent the food materials from being crushed by the scraper. When cooking harder or more viscous food materials such as nuts and glutinous rice balls, a larger pressure is required to ensure the stir-frying effect. The adjustable spring force of the spring 5 can conveniently adjust the scraper pressure according to the type of food materials and the cooking process, realize precise cooking, and improve the cooking quality and flexibility. The scraper pressure can be adjusted in time according to the wear condition of the inner wall of the wok. For example, when the wok is new, the inner wall is relatively smooth, and the pressure can be appropriately reduced. As the use time increases and the inner wall is worn to a certain extent, the pressure can be appropriately increased to maintain good stir-frying effect. In this way, further excessive wear of the wok inner wall caused by the scraper pressure being fixed and still applying a large pressure after the wok inner wall is worn can be avoided, thereby prolonging the service life of the wok and the scraper and reducing the equipment update cost.
