Description

Technical Field

[0001] The utility model relates to the field of water tanks, in particular to a buckling sealing structure of a water tank. Background Art

[0002] As people's living standards continue to improve, small household cleaning devices such as steam mops and hanging irons are becoming increasingly popular. These devices generally have a water tank and a steam generator, which generates high-temperature steam by heating the water in the water tank and sprays it from the nozzle to improve the cleaning effect. In the prior art, the water tank and the main body of the device are only fixed by a simple card slot when assembled, which has the problem of poor sealing. When the water tank is removed from the main body of the device, it will not automatically seal and is prone to water leakage and seepage. In addition, since the water tank lacks a positioning structure, it is easy to loosen during the use of the device, affecting the user experience. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a water tank buckle sealing structure with automatic sealing and positioning functions. The water tank is automatically sealed after being removed from the main body to prevent water leakage in the water tank.

DETAILED DESCRIPTION

[0031] The utility model will be described in detail below with reference to the accompanying drawings:

[0032] Example: As attached Figures 1 to 12 As shown, this water tank snap-fit ​​sealing structure includes a main body shell 1, a water tank body 2, a water tank bottom shell 3, a matching notch 4, a boss 5, a water outlet hole 6, a water outlet channel 7, a sealing spring 8, a sealing rubber plug 9, a sealing steel ball 10, a main body water inlet column 11, a water inlet notch 12, a water pump 13, a positioning column 14, a positioning column spring 15, a water tank mounting groove 16, a positioning protrusion 17, a positioning slide groove 18, a positioning hole 19, a positioning pit 20 and a spring seat 21.

[0033] Reference Figure 6A water tank installation groove 16 is provided at the lower part of the host housing 1, and the host housing 1 protrudes toward the direction where the water tank installation groove 16 is located (i.e., protrudes downward) to form a boss 5, and a host water inlet column 11 connected to the host housing 1 is provided at the front end of the boss 5, such as Figure 2 , 4 As shown, the main engine water inlet column 11 is connected to the water inlet end of a water pump 13 installed in the main engine housing 1, and the water outlet end of the water pump 13 supplies water to the main equipment (which may be a steam generator) in the main engine housing 1.

[0034] like Figure 2 , 4 As shown in FIGS. 7 and 12 , the water tank body 2 is installed in the water tank installation groove 16 , and a matching notch 4 is provided at the back of the water tank body 2 corresponding to the boss 5 , and the matching notch 4 and the boss 5 form a concave-convex fit, thereby positioning the water tank body 2 and the host housing 1 . Fig. 9 , 10 As shown, a water outlet hole 6 connected to the inner cavity of the water tank body 2 is opened on the inner wall of the matching notch 4, and a water outlet channel 7 connected to the inner cavity of the water tank body 2 is opened on the inner wall of the water outlet hole 6. The lower end of the water tank body 2 is fixedly mounted on the water tank bottom shell 3 by a slot type.

[0035] Reference Figure 4 , 10 The sealing spring 8, the sealing rubber plug 9 and the sealing steel ball 10 form a sealing assembly, wherein the sealing rubber plug 9 is installed at the mouth of the water outlet 6 and can cooperate with the main unit water inlet column 11. The sealing spring 8 is arranged in the water outlet 6. Preferably, a spring seat 21 is arranged on the inner wall of the water outlet 6, and the sealing spring 8 is installed on the spring seat 21. The sealing steel ball 10 is pressed against the sealing spring 8. When the water tank body 2 is separated from the main unit housing 1, the sealing spring 8 presses the sealing steel ball 10 against the sealing surface of the sealing rubber plug 9, as shown in FIG. Fig.10 As shown, automatic sealing is achieved to effectively prevent water tank leakage. When the water tank body 2 is buckled into the host housing 1, the host water inlet column 11 is inserted into the sealing rubber plug 9, and the sealing steel ball 10 is pushed open, so that the water outlet 6 is connected to the host housing 1 to discharge water. Figure 6 As shown, preferably, four water inlet gaps 12 are opened along the circumferential direction at the mouth of the main engine water inlet column 11. Since the sealing steel ball 10 is in contact with the mouth of the main engine water inlet column 11, when the main engine water inlet column 11 pushes the sealing steel ball 10 away, the water in the water outlet 6 can enter the main engine water inlet column 11 from the water inlet gaps 12.

[0036] like Figure 8 , 9As shown in Figures 11, a positioning component is provided at the bottom of the water tank installation groove 16 (host housing 1) to facilitate positioning of the water tank bottom shell 3. The positioning component includes two positioning grooves 18 provided on the host housing 1, and two positioning protrusions 17 corresponding to the positioning grooves 18 are provided on the water tank bottom shell 3. When the water tank body 2 is buckled into the host housing 1, the positioning protrusions 17 slide into the positioning grooves 18 to achieve positioning and guiding. In addition, the positioning component also includes positioning holes 19 and positioning columns 14. A positioning hole 19 is provided on the host housing 1 behind each positioning groove 18. A positioning column 14 (such as a positioning column spring 15) is elastically supported in each positioning hole 19. Figure 6 As shown), a positioning pit 20 corresponding to the positioning column 14 is provided on the water tank bottom shell 3. When the water tank body 2 is buckled into the host shell 1, the positioning column 14 is just snapped into the positioning pit 20 to achieve positioning.

[0037] The working process of this utility model:

[0038] When the water tank body 2 is removed from the host housing 1, the sealing steel ball 10 presses against the sealing rubber plug 9 under the force of the sealing spring 8, thereby ensuring that the water tank remains sealed after being removed and water cannot flow out of the water tank.

[0039] When the water tank body 2 is snapped into the host housing 1, the main water inlet column 11 is inserted into the sealing plug 9 and pushes the sealing steel ball 10, so that the sealing steel ball 10 is displaced and separated from the sealing surface of the sealing plug 9. Under the action of the water pump 13, the water in the water tank body 2 is pumped out, passing through the water outlet channel 7 (a water pump hose can be installed), the water outlet hole 6, the main water inlet column 11, and the water pump 13 in sequence, and finally the water outlet end of the water pump 13 supplies water to the main equipment (which can be a steam generator) in the host housing 1.

[0040] When the water tank body 2 is pushed to the designed position, the positioning post 14 is bounced up by the positioning post spring 15 and is stuck into the positioning pit 20 provided on the water tank bottom shell 3, so as to fix the water tank when it is used.

[0041] It is understandable that, for those skilled in the art, any equivalent replacement or change to the technical solution and the concept of the utility model should fall within the protection scope of the claims attached to the utility model.
