Description

Technical Field

[0001] The utility model relates to the field of household appliances, and particularly relates to a cup rinsing nozzle with adjustable height. Background Art

[0002] An appliance used in the market to clean single-sided open cups such as teacups, water cups, teapots, kettles, milk tea cups, etc. is called a teacup cleaning machine. Traditional teacup cleaning machines can only perform water spraying or water bath soaking, and cannot effectively clean the tea residues at the bottom of the cup, resulting in general cleaning effects. With the development of technology, in recent years, there has emerged a cleaning machine that can better clean cups after the teacup is placed upside down. For example, Chinese invention patent application: Application No. 202010375501.3 discloses a teacup cleaning machine that sprays water from the nozzle below to clean the teacup, achieving better cleaning effects. However, the disadvantage is that the height of the nozzle of this cleaning machine cannot be adjusted (i.e., the height position of the nozzle relative to the supporting frustum is determined), and it can only be applicable to cups of a certain height and cannot flexibly adjust the height position according to the height of the cup.

[0027] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0028] As Figures 1 to 4 shown, an adjustable-height rinsing cup spray head includes a spray head 1, a lifting shaft 2, and a fixed seat 3. The spray head 1 is installed above the lifting shaft 2. A fixed column 4 is provided in the fixed seat 3. The fixed column 4 is provided with an installation hole 5. The lower part of the lifting shaft 2 penetrates into the installation hole 5. The lifting shaft 2 is of a hollow structure to facilitate the water to be transported from the lifting shaft to the spray head 1. A plurality of card slots 6 are set on the outer side of the lifting shaft 2. The plurality of card slots 6 are arranged along the axial direction of the lifting shaft. An elastic engaging member 7 is installed in the fixed column 4. When the lifting shaft 2 moves up and down, it will drive the spray head 1 to move together; the elastic engaging member 7 is snapped into different card slots 6 to realize the adjustment of the height of the spray head 1.

[0029] As Figure 4 and 5As shown, two planes are provided on both sides of the slot 6, one plane is an anti-rotation plane 8a, which extends downward along the axial direction of the lifting shaft 2 and penetrates to the bottom of the lifting shaft, and the corresponding mounting hole 5 also has a plane to prevent the lifting shaft 2 from rotating, and the other plane is an anti-escape plane 8b, which extends downward along the axial direction of the lifting shaft and does not penetrate to form a limiting step 8c. When the lifting shaft 2 moves to the highest position, the limiting step 8c contacts the elastic engaging part 7 to support the lifting shaft 2 to continue to move upward.

[0030] like Figure 6 As shown, the elastic clamping member 7 includes a main body 71, a clamping plate portion 72 and a hooking portion 73. The main body 71 is embedded in the fixing column 4. The left and right sides of the main body 71 are respectively connected to a clamping plate portion 72. The inner side of the clamping plate portion 72 extends into the mounting hole 5 to clamp the clamping slot 6 so as to fix the position of the lifting shaft 2. The end of the clamping plate portion 72 is connected to the hooking portion 73.

[0031] like Figure 7 As shown, the cross-sectional shape of the elastic engaging member 7 when viewed from above is circular, and the left and right hook portions 73 extend toward the center line and form an opening 74 therebetween. The extension of the hook portion 73 toward the center line is conducive to the clamping of the fixing column 4, and the opening 74 is formed between the left and right hook portions 73 for the convenience of installing the fixing column.

[0032] like Figure 8 As shown, the cross-section of the main body 71 is in the shape of a U-shape, and the bottom of the main body 71 is staggered with the clamping plate 72 to form a height difference, which can increase the strength of the parts. In addition, the inner side surface of the clamping plate 72 is an arc surface 75, and the arc surface 75 is provided to facilitate better up and down movement of the lifting shaft 2. The main body 71 is provided with a mounting hole 76, and the fixing column 4 is provided with a protrusion 41 that matches the mounting hole 76. The elastic clamping member 7 is inserted into the mounting hole 76 through the protrusion 41 to achieve installation on the fixing column 4.

[0033] like Figure 9 As shown, a cup rack 9 is provided above the fixed seat 3, and the nozzle 1 extends from the center of the cup rack 9. The cup rack 9 is mainly composed of separated plates. The cup 10 is placed on the cup rack 9 with its opening facing downward. The cups with a single opening are such as tea cups, water cups, teapots, kettles, milk tea cups, bean juice cups, fruit cups, etc. The cup 10 covers the nozzle 1. When the elastic clamping member 7 is inserted into different slots, the distance between the nozzle 1 and the cup rack 9 is different. The bottoms of cups of different heights are at different heights. The height change of the nozzle 1 can make it more flexible to approach the bottom of the cup, and the sprayed water can clean the bottom of the cup to ensure a cleaner appearance.

[0034] like Figure 4 As shown, the main body 1a of the nozzle 1 is a cylinder, and the upper part of the cylinder is connected to a mushroom-shaped sheet 1b, and the water spraying groove 1c is arranged on the sheet 1b. The nozzle 1 is arranged to have a large upper end and a small lower end, so that it is convenient for people to hold the nozzle 1 and move it up and down. Figure 10As shown, a convex step 2a is provided at the upper end of the lifting shaft 2. The convex step 2a is installed inside the spray head 1 and is located in the water spraying chamber. The outer diameter of the convex step 2a is larger than the outer diameter of the main body 2b of the lifting shaft. A bearing 11 is sleeved on the outer peripheral side of the main body 2b of the lifting shaft. The bearing 11 is installed in the bearing installation cavity of the spray head 1. A limit snap ring 12 is installed at the lower part of the spray head 1. The limiting edge of the limit snap ring 26 abuts against the bearing 11, which can prevent the separation of the spray head 1 from the lifting shaft 2.

[0035] The above content is a further detailed description of the present utility model in combination with specific preferred embodiments. It cannot be determined that the specific implementation of the present utility model is only limited to these descriptions. For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, which should all be regarded as belonging to the protection scope of the present utility model.
