Description

Technical Field

[0001] This utility model relates to the field of fabric machine technology, and more specifically, to a clean water tank for a fabric machine. Background Technology

[0002] The water tank of a fabric knitting machine is an important component. Currently, most water tanks on the market consist of a body and a lid. The lid is detachably connected to the opening at the top of the body and is sealed circumferentially. When the water tank is assembled onto the main unit of the fabric knitting machine, and the water pump draws water from the tank, an air inlet is provided on the lid to ensure pressure balance within the tank and to facilitate water extraction. Additionally, to prevent the water tank from being tipped over... When the water tank is placed upright, water leaks out from the air inlet. A sealing gasket is installed at the air inlet. That is, when the water tank is placed upright, the sealing gasket can release the air inlet. When the water tank is removed from the fabric machine and briefly inverted, the sealing gasket can seal the air inlet to prevent water from leaking out. However, in the above water tank structure, when the water tank is inverted, the sealing gasket is needed to seal the air inlet, which has the disadvantages of complex structure and high component cost. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a water tank for a fabric machine that eliminates the use of a sealing gasket, making the structure of the water tank simpler and having the advantage of low production cost.

[0004] This utility model provides a clean water tank for a fabric knitting machine, including a tank body and a cover assembly; the cover assembly is detachably connected to the opening at the upper end of the tank body and is circumferentially sealed to the tank body; the cover assembly includes a lower cover and an upper cover; the lower end of the upper cover is fixed to the upper end of the lower cover; the upper cover and the lower cover form a water storage cavity, a first vent is provided at the upper end of the lower cover and at the bottom of the water storage cavity, and a second vent is provided on the side wall of the upper cover and communicates with the water storage cavity, the second vent being located in the middle of the vertical direction of the water storage cavity.

[0005] By adopting the above-described structure, this invention ensures that when the clean water tank of the fabric machine is placed upright on the main body of the fabric machine, air from the external environment can enter the tank through the second vent and the first vent, thus maintaining the air pressure balance within the clean water tank. Furthermore, when the clean water tank is removed from the main body of the fabric machine and briefly inverted, even if water leaks from the tank through the first vent, it can be temporarily stored in the water storage chamber. Additionally, because the second vent is located vertically within the water storage chamber... The water is positioned in the middle of the storage chamber, thus preventing water from leaking out through the second vent when there is only a small amount of water in the storage chamber. This invention eliminates the need for a sealing gasket, preventing water from leaking out of the fabric machine's water tank when it is briefly inverted. Because the sealing gasket is eliminated, the structure of the fabric machine's water tank is simpler and has the advantage of low production cost. In addition, when the fabric machine's water tank is turned upright again, the water in the storage chamber can flow back into the tank through the first vent.

[0006] In one possible implementation, the water storage cavity is located inside the upper cover, forming a structure with an opening at the lower end. The upper cover and the upper end of the lower cover located at the lower opening of the water storage cavity are ultrasonically welded and circumferentially sealed. With this structure, after the upper cover and the lower cover are fixed, the aforementioned water storage cavity can be easily formed between the upper cover and the lower cover. Since the upper cover and the upper end of the lower cover located at the lower opening of the water storage cavity are ultrasonically welded and circumferentially sealed, the lower end of the upper cover can be reliably fixed together with the upper end of the lower cover.

[0007] In one possible implementation, the front side of the cover is inserted into the front side of the upper end of the box, and the rear side of the cover is snapped into the rear side of the upper end of the box; with this structure, the cover assembly can be easily and detachably connected to the opening at the upper end of the box.

[0008] In one possible implementation, the front side of the cover is provided with two symmetrical inserts, and the front side of the upper end of the box is provided with a corresponding insertion hole for each of the two inserts. Each insert is inserted into the corresponding insertion hole. With this structure, the front side of the cover assembly can reliably and conveniently engage with the front side of the box when the cover assembly is assembled with the box, thanks to the cooperation of the inserts and the insertion holes.

[0009] In one possible implementation, a spring buckle is provided in the middle of the rear side of the top cover, and a corresponding hook is provided on the rear side of the upper end of the box body. The spring buckle and the hook engage with each other. With this structure, under the combined action of the spring buckle and the hook, when the cover assembly is assembled with the box body, the rear side of the cover assembly can reliably and conveniently engage with the rear side of the box body.

[0010] In one possible implementation, the lower end of the snap fastener is integrally formed with an extension section that gradually slopes backward from top to bottom. With this structure, when the cover assembly needs to be removed from the box, the fingers can press against the extension section and pry the snap fastener outward. At this time, the snap fastener can be easily disengaged from the hook, thereby facilitating the removal of the cover assembly from the box.

[0011] In one possible implementation, a sealing ring is embedded on the outer wall of the lower end of the cover, and the lower end of the cover is inserted into the opening at the upper end of the box. The cover and the box are circumferentially sealed by the sealing ring. With this structure, the lower end of the cover can be reliably circumferentially sealed to the box by the sealing ring, that is, the cover assembly can be reliably and circumferentially sealed to the upper end of the box.

[0024] The lower end of the spring clip 34 is integrally formed with an extension section 341 that gradually slopes backward from top to bottom. With this structure, when the cover assembly needs to be removed from the box, the finger can press against the extension section and pull the spring clip outward. At this time, the spring clip can be easily disengaged from the hook, so that the cover assembly can be easily removed from the box.

[0025] A sealing ring 4 is embedded on the outer wall of the lower end of the lower cover 2. The lower end of the lower cover 2 is inserted into the opening at the upper end of the box body 1. The lower cover 2 and the box body 1 are circumferentially sealed by the sealing ring 4. With this structure, under the action of the sealing ring, the lower end of the lower cover can be reliably circumferentially sealed to the box body, that is, the cover assembly can be reliably circumferentially sealed to the upper end of the box body.
