DETAILED DESCRIPTION

[0022] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings, but the utility model is not limited to these embodiments.

[0023] As Figures 1-6 shown, the connection structure of the kettle cover and the kettle of the foam sprayer, including kettle body 1 and kettle cover 2, the upper end of kettle body 1 has kettle neck 10, kettle cover 2 covers kettle neck 10, the outer circumferential surface of kettle neck 10 is provided with annular clamping flange 11, the left and right sides of kettle cover 2 are provided with kettle buckle 3, kettle buckle 3 is hinged on kettle cover 2 and can swing left and right, the lower end of kettle buckle 3 has hook part 30 hooked on the lower surface of clamping flange 11, spring 4 is arranged on kettle cover 2 to make kettle buckle 3 hook tightly on the lower surface of clamping flange 11. When the kettle cover 2 and the kettle body 1 are installed, first, the kettle cover 2 is covered on the kettle neck 10, the hook part 30 at the lower end of the kettle buckle 3 is hooked on the lower surface of the clamping flange 11, the spring 4 is arranged to make the hook part 30 hook tightly on the lower surface of the clamping flange 11, the two kettle buckles 3 are arranged to make the left and right sides of the kettle cover 2 hook tightly on the lower surface of the clamping flange 11, thereby realizing the installation and positioning of the kettle cover 2 and the kettle body 1. When it is needed to disassemble the kettle cover 2 from the kettle body 1, only the kettle buckle 3 needs to be pressed, the lower end of the kettle buckle 3 swings outward to make the hook part 30 at the lower end of the kettle buckle 3 separate from the clamping flange 11, thereby making the kettle cover 2 and the kettle body 1 unlock, at this time, the kettle cover 2 can be directly moved upward and out. The connection structure of the kettle cover 2 and the kettle body 1 is simple, and time and labor are saved when installing and disassembling, and the convenience of installing and disassembling the kettle cover 2 and the kettle body 1 is significantly improved.

[0024] As Figure 1 , Figure 2 and Figure 4As shown, the left and right sides of the lid 2 are provided with installation grooves 20, and the lid buckle 3 is arranged in the installation groove 20. The middle part of the lid buckle 3 is hinged to the lid 2 through a rotating shaft. The inner wall of the installation groove 20 is provided with a clearance hole 21. The hook part 30 at the lower end of the lid buckle 3 passes through the clearance hole 21 and hooks the lower surface of the clamping flange 11. The lid buckle 3 has a pressing part 31 which extends upward out of the installation groove 20. The inner wall of the installation groove 20 has a positioning seat 22. The lower end of the spring 4 is arranged in the positioning seat 22. The upper end of the spring 4 abuts against the lid buckle 3. The design of the installation groove 20 facilitates the installation of the lid buckle 3. The design of the clearance hole 21 facilitates the hook part 30 to hook the lower surface of the clamping flange 11. The arrangement of the pressing part 31 facilitates the user to press the lid buckle 3 with fingers, that is, to drive the lid buckle 3 to swing. The operation is very labor-saving, and further facilitates the convenience of the installation and dismounting of the lid 2 and the kettle body 1.

[0025] As shown in Figure 2 and Figure 3 , the outer edge of the upper surface of the clamping flange 11 has a guide slope one 110. The outer edge of the lower surface of the hook part 30 has a guide slope two 300. The guide slope two 300 can abut against the guide slope one 110 and make the hook part 30 move below the clamping flange 11 along the guide slope one 110. The lid 2 is installed on the kettle neck part 10 from top to bottom. The guide slope two 300 contacts the guide slope one 110, so that the lid 2 is smoothly installed on the kettle neck part 10. Under the action of the spring 4, the lid buckle 3 tightly buckles the clamping flange 11.

[0026] As shown in Figure 1 , Figure 5 , and Figure 6 , the outer wall of the upper end of the kettle body 1 has a downwardly recessed positioning groove 12. The lid 2 has a positioning protrusion 23 which extends into the positioning groove 12. When the lid 2 is installed on the kettle body 1, the lid buckle 3 limits the up and down of the lid 2. The cooperation between the positioning protrusion 23 and the positioning groove 12 realizes the circumferential positioning of the lid 2, so that the stability of the installed lid 2 is ensured and displacement does not occur.

[0027] As shown in Figure 2 , Figure 3 , a sealing ring 5 is sleeved on the outer periphery of the kettle neck part 10. The sealing ring 5 is located above the clamping flange 11. The lid 2 has a sealing ring 24 which contacts the sealing ring 5. After the lid 2 is installed on the kettle neck part 10, the inner periphery of the sealing ring 24 tightly contacts the sealing ring 5, so that sealing is realized.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways, without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
