Abstract
Description
Technical Field
[0001] This utility model relates to the field of puncture device technology, specifically an automatic puncture device. Background Technology
[0002] Automatic dishwashers are widely used in large-scale catering industries due to their efficient dishwashing capabilities. Because their efficient and continuous washing process requires a constant supply of dishwashing liquid, they are usually equipped with a dishwasher refill device.
[0003] Typically, such cleaning fluid filling devices do not need to be too complicated. They only need a switch to allow the cleaning fluid to flow into a designated location inside the dishwasher. However, in existing technologies, the cleaning fluid container usually needs to be manually punctured before being placed in the corresponding location. This results in slow efficiency, a high degree of manual intervention, and waste of cleaning fluid.
[0004] In view of the above problems, this utility model designs an automatic puncture device. Simply place the cleaning liquid tank directly on the device to achieve automatic puncture. Equipped with a liquid level sensor and an automatic locking device, it reduces the degree of manual intervention, complements the continuous cleaning work of the dishwasher, and greatly improves work efficiency. Summary of the Invention
[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an automatic puncture device. Simply place the cleaning fluid tank directly on the device to achieve automatic puncture. Equipped with a liquid level sensor and an automatic locking device, it reduces the degree of manual intervention and, in conjunction with the continuous cleaning work of the dishwasher, greatly improves work efficiency.
[0006] To achieve the above objectives, this utility model provides an automatic puncture device, including a device body and a liquid tank. The device body has an internal mounting surface, and the mounting surface has a hollowed-out recess at the bottom. A spike is provided at the bottom of the recess, and a cover groove is provided close to the inner side of the recess. A sensor lock is provided close to the inner side of the cover groove.
[0007] The inner side of the mounting surface is provided with a slope.
[0008] Handles are provided on both sides of the main body of the device.
[0009] Reinforcing columns are installed on the partition between adjacent mounting surfaces.
[0010] The liquid tank has a liquid outlet at the bottom.
[0011] The height of the liquid outlet is greater than the depth of the mounting surface.
[0012] The outside of the liquid outlet is connected to a bucket lid via a thread.
[0013] Compared with the prior art, this utility model can pierce the lid of the liquid tank with a spike, realizing the automatic flow of the cleaning liquid in the tank into the dishwasher for cleaning. At the same time, since there is a sensor lock next to the liquid outlet of the liquid tank, the liquid in the tank can be monitored and the outlet can be locked to ensure the safety of use. Furthermore, the lock will automatically unlock when no liquid is detected in the tank, making it convenient for staff to replace the liquid in a timely manner. Attached Figure Description
[0014] Figure 1 This is a three-dimensional schematic diagram of the present invention.
[0015] Figure 2 This is a schematic diagram of the liquid tank of this utility model.
[0016] 1 is the device body, 2 is the mounting surface, 3 is the recess, 4 is the spike, 5 is the cover groove, 6 is the sensor lock, 7 is the reinforcing column, 8 is the inclined surface, 9 is the handle, 10 is the liquid tank, and 11 is the liquid outlet. Detailed Implementation
[0017] The present invention will now be further described with reference to the accompanying drawings.
[0018] See Figures 1-2 This utility model provides an automatic puncture device, including a device body 1 and a liquid tank 10. The device body 1 has an installation surface 2 inside, and the installation surface 2 has a hollowed-out recess 3 at the bottom. A spike 4 is provided at the bottom of the recess 3. A cover groove 5 is provided close to the inner side of the recess 3, and a sensor lock 6 is provided close to the inner side of the cover groove 5.
[0019] An inclined surface 8 is provided on the inner side of the mounting surface 2 to allow liquid to flow back into the interior of the mounting surface 2.
[0020] The device body 1 is provided with handles 9 on both sides to facilitate the installation, removal or movement of the device.
[0021] A reinforcing column 7 is provided on the partition between adjacent mounting surfaces 2, which strengthens the bottom structure of the device body 1.
[0022] The bottom of the liquid tank 10 is provided with a liquid outlet 11. The height of the liquid outlet 11 is greater than the depth of the mounting surface 2. The outside of the liquid outlet 11 is connected to a tank cover by a thread, so that the spike 4 can be inserted into the tank cover of the inverted liquid tank 10.
[0023] Working principle:
[0024] This invention requires minimal adjustment during use. First, install the lid by inserting it into the lid slot 5, with the pre-drilled protrusion 4 exposed. Then, invert the liquid tank 10 (with the lid installed) onto the recess 3. After piercing the lid with the protrusion 4, invert the liquid tank 10 onto the device. The cleaning fluid inside the liquid tank 10 flows into the dishwasher through the opening at the bottom of the recess 3. At this point, the sensor lock 6 next to the lid slot 5 detects the liquid and locks the lid in place, preventing it from moving. When the sensor inside the sensor lock 6 detects no liquid inside the lid, it automatically unlocks, allowing the liquid tank 10 to be replaced.
[0025] The above are merely preferred embodiments of this utility model, intended only to aid in understanding the method and core concept of this application. The scope of protection of this utility model is not limited to the above embodiments; all technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the scope of protection of this utility model.
[0026] In the description of this utility model, it should be noted that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0027] This invention solves the inconvenience of manually piercing the cleaning fluid device in traditional dishwashers, which requires manual installation. An automatic piercing device allows the fluid tank to be inverted and inserted into the device to pierce the fluid, enabling direct operation with the dishwasher. It also features a sensor lock to protect the fluid tank and ensure safe, uninterrupted, and stable operation. This invention provides a continuous and stable cleaning fluid supply, and the fluid tank can be replaced quickly and easily without excessive manual intervention, ensuring long-term stable operation of the dishwasher.
