[0002] In the production and application field of ice cream machine and other equipment, liquid level monitoring plays a crucial role in ensuring the stability of production process, the reliability of product quality and the efficient operation of equipment. Traditional ice cream machines usually use relatively simple liquid level sensing devices, such as ordinary material shortage sensors, but such sensors expose many serious problems in actual use.

[0003] The sensitivity of ordinary material shortage sensors is generally low. The characteristics of ice cream raw materials are complex, and a large amount of foam is easily produced during stirring and conveying. Ordinary sensors cannot accurately distinguish between foam and real liquid level, often misjudging foam as liquid, resulting in failure to detect real liquid level changes in time and accurately. This not only affects the timely replenishment of raw materials in the ice cream production process and reduces production efficiency, but also may cause uneven quality and taste of ice cream due to insufficient supply of raw materials.

[0004] Most existing sensors only have material shortage sensing function and lack full material indication. In actual production scenarios, operators cannot know whether the material tank has been added to the appropriate liquid level in real time, which may easily cause over-addition or insufficient addition of raw materials. Over-addition not only causes waste of raw materials, but also may cause equipment failure; insufficient addition will affect the continuity of production.

[0005] Due to the above defects of ordinary liquid level sensors, the customer's use experience is greatly reduced, and the development of the ice cream machine industry is also limited. Therefore, it is an urgent need in the industry to develop an electronic metal liquid level meter with high sensitivity, full and lack of material double indication function, firm installation and not easy to damage.

[0027] The following will refer to the appendix in the example of this utility model. Figures 1-5The technical solutions of the embodiments of the utility model are clearly and completely described, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments, based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without making creative labor belong to the range of the utility model protection.

[0028] An electronic metal liquid level meter, including the mounting seat 1, the upper edge of mounting seat 1 is embedded with metal sleeve 2, the upper part of metal sleeve 2 is embedded with intermediate sleeve 3, the upper part of intermediate sleeve 3 is sleeved with metal head 4, the inside axis of metal head 4 is fixedly provided with center rod 5, and center rod 5 penetrates to the bottom of mounting seat 1;

[0029] Mounting seat 1 is used as the connecting part of liquid level meter and ice cream machine tank, is connected with the tank of ice cream machine at the bottom, provides mounting support for the whole liquid level meter, and ensures that the liquid level meter is stably installed at the bottom of the tank.

[0030] The bottom of mounting seat 1 is provided with first wiring hole 11, and the side of mounting seat 11 is symmetrically provided with process gap 12. Mounting seat 1 is made of plastic material, is provided with through hole 13 in the inside, and is connected with center rod 5. First wiring hole 11 provides a wiring channel for the line of control system, so that the line can be connected to each component in order, avoids signal interference or line damage caused by disorderly line, and guarantees the stability of liquid level meter signal transmission. Process gap 12 facilitates the operator to use tools to fasten when installing and dismounting liquid level meter, reduces the installation and maintenance difficulty, and improves work efficiency. The plastic material has insulation, can prevent short circuit between metal components, and guarantees the electrical safety of liquid level meter. The internal through hole 13 is used for inserting with center rod 5, not only provides support for the center rod, so that it can stably penetrate each component, but also determines the relative position between each component, guarantees the accuracy of the overall structure of liquid level meter. In addition, the plastic material is light in weight and low in cost, which helps to reduce the overall cost of liquid level meter.

[0031] The metal sleeve 2 is a hollow cylinder as a whole, and a convex annular ring 21 is arranged on the outer edge of the middle part, the upper end is sleeved with the middle sleeve 3, the lower end is sleeved with the mounting base 1, and annular grooves 22 are arranged at the upper and lower ends of the annular ring 21. The hollow design reduces the weight of the metal sleeve itself, provides space for the center rod 5 to pass through, and ensures that the center rod can penetrate through each part to build the overall structure of the liquid level meter. In addition, this shape design increases the contact area with the liquid, optimizes the sensing effect, and ensures the accuracy of the lack of material sensing. The convex annular ring 21 plays a role in positioning and reinforcing the connection. On the one hand, when sleeving with the mounting base 1 and the middle sleeve 3, the annular ring 21 can accurately determine the position of the metal sleeve 2, preventing the metal sleeve from shifting during installation; on the other hand, the contact area with other parts is increased, the stability of the connection is enhanced, and the stability of the liquid level meter during work is ensured.

[0032] The grooves 22 can accommodate sealing materials such as rubber rings, further enhancing the sealing performance of the connection between the metal sleeve 2 and the mounting base 1 and the middle sleeve 3, preventing liquid leakage and affecting liquid level sensing. At the same time, the groove structure changes the electric field distribution around the metal sleeve, optimizes the sensing performance of the metal sleeve to the liquid level change, and improves the accuracy of the lack of material sensing. The grooves can optimize the electric field distribution of the metal sleeve, thereby improving the accuracy of the liquid level sensing. When sensing the liquid level, the metal sleeve as a lack of material sensing component, the electric field state around it will change with the liquid level. The grooves change the local shape and size of the metal sleeve, improve the uniformity and strength of the electric field distribution, and enable the metal sleeve to more accurately sense the presence or absence of liquid at different liquid level heights, transmit more accurate signals to the control system, and reduce the occurrence of misjudgment.

[0033] The middle sleeve 3 is made of plastic and is hollow inside. On the one hand, it separates the metal sleeve 2 and the metal head 4 by a certain distance, ensuring that both can independently and accurately function during liquid level sensing, avoiding mutual interference; on the other hand, the plastic material has insulation properties, preventing electrical short circuit between the metal sleeve 2 and the metal head 4, and ensuring the accuracy of the liquid level meter sensing signal. At the same time, the hollow design of the middle sleeve 3 provides space for the center rod 5 to pass through, ensuring the integrity of the overall structure of the liquid level meter.

[0034] The metal head 4 is made of stainless steel and is used for full material sensing. When the liquid level is higher than the position of the metal head 4, the metal head 4 is in contact with the liquid, the circuit is conducted, and the full material signal is transmitted to the control system. The inner thread at the bottom is used for threaded connection with the upper end of the center rod 5, ensuring the fixed position of the metal head 4 in the liquid level meter and ensuring the stable realization of the full material sensing function.

[0035] The central rod 5 is made of stainless steel, and the threads at the upper and lower ends of the central rod 5 play an important role. The upper end thread is connected with the inner thread of the metal head 4, and the lower end thread can be used for wiring or connecting with other components, thereby achieving the function of transmitting the sensing signal of the metal sleeve 2 to the control system. Meanwhile, the central rod 5 penetrates through the mounting seat 1, the metal sleeve 2, the intermediate sleeve 3 and the metal head 4, and tightly connects the components together, thereby constructing the overall structure of the liquid level meter and ensuring the cooperative work of the components and realizing the liquid level sensing function.

[0036] Working principle:

[0037] Component cooperative architecture: The mounting seat is fixed to the bottom of the ice cream machine tank and provides support for the entire liquid level meter. The central rod penetrates through the mounting seat, the metal sleeve, the intermediate sleeve and the metal head, and connects the components into a whole. The metal sleeve is responsible for the lack of material sensing, the metal head is responsible for the full material sensing, the intermediate sleeve separates the two to ensure independent sensing, and the mounting seat provides a wiring channel for the line and assists in installation.

[0038] Liquid level sensing mechanism: When the liquid level in the tank changes, the contact state of the metal sleeve and the metal head with the liquid changes accordingly. Since the two are conductors, when the liquid level is lower than the position of the metal sleeve, the metal sleeve is not in contact with the liquid, and the circuit is in an open state, and the lack of material signal is disconnected. The signal is transmitted to the control system through the central rod, and the control system instructs the lack of material according to the signal. When the liquid level is higher than the position of the metal head, the metal head is in contact with the liquid, the circuit is conducted, and the full material signal is transmitted to the control system through the central rod, and the control system displays the full material. In this way, the electronic metal liquid level meter realizes real-time monitoring of the liquid level and accurately feeds back the liquid level state to the control system, thereby providing accurate control basis for the raw material supply of the ice cream machine.

[0039] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
