[0017] Figure 1 This is a cross-sectional schematic diagram of the first embodiment of the present invention.
[0018] Figure 2 This is a schematic diagram of the structure of the isolation cover according to the first embodiment of this utility model.
[0019] Figure 3 This is a schematic diagram of the structure of the isolation cover according to the second embodiment of this utility model. DETAILED DESCRIPTION
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] First embodiment:
[0022] See Figure 1 , Figure 2This drain assembly includes an outer drain shell 1 and an inner drain shell 2 fitted inside it from top to bottom. The outer drain shell 1 and the inner drain shell 2 each have a drain cavity 11 and a drain cavity 21, respectively. The inner drain shell 2 is provided with a drain outlet 22. The drain cavity 11 and the drain cavity 21 are connected through the drain outlet 22. The inner drain shell 2 is provided with a switch assembly 3 at the position corresponding to the drain outlet 22, which can open or close the drain outlet 22. An isolation cover 4 is connected to the upper opening end of the inner drain shell 2. An isolation structure is formed between the isolation cover 4 and the inner drain shell 2 to prevent the residue in the drain cavity 21 from leaving the drain cavity 21 through the upper opening of the inner drain shell 2. The isolation cover 4 can be linked with the switch assembly 3 to open or close the drain outlet 22.
[0023] When the user needs to open or close the drain outlet 22, there is no need to open the isolation cover 4. That is, the residue in the drain chamber 21 will not flow back to the space outside the isolation cover 4 corresponding to the kitchen sink. Therefore, when the kitchen sink is used repeatedly, there is no need to clean the residue in the drain outlet 22 each time to prevent the residue in the drain outlet 22 from flowing back to the space inside the kitchen sink the next time it is used. This can reduce the frequency of cleaning the drain outlet 22 and improve the convenience of the user in using the product.
[0024] In this embodiment, the switch assembly 3 can be a conventional spring switch, which is a device that can achieve positioning and keep the elastic reset member deformed when pressed for the first time, and reset the elastic reset member when pressed for the second time. The specific structure of such a spring switch belongs to the prior art and is widely used in the field, which can be understood by those skilled in the art.
[0025] Furthermore, the upper side of the isolation cover 4 has a sealed surface structure, and a sealing ring (not shown in the figure) is connected to the outer side of the isolation cover 4.
[0026] When the isolation cover 4 is linked to the switch assembly 3 to open the drain outlet 22, the sealing ring separates from the inner lower water shell 2, and a drainage structure is formed between the isolation cover 4 and the outer lower water shell 1. At this time, the water in the kitchen sink can flow normally into the drain chamber 21 through the drainage structure, and finally drain into the drain chamber 11 from the drain outlet 22.
[0027] When the isolation cover 4 is linked to the switch assembly 3 to disconnect the drain outlet 22, the sealing ring is tightly fitted with the isolation cover 4 and the inner lower water shell 2 respectively. At this time, the residue and water in the drain chamber 21 will not flow back into the space inside the kitchen sink, and the user can store water in the kitchen sink.
[0028] Furthermore, the outer side of the isolation cover 4 is provided with a limiting groove 41 corresponding to the sealing ring. The sealing ring is embedded in the limiting groove 41, which improves the connection strength and installation accuracy between the sealing ring and the isolation cover 4, and prevents the sealing ring from accidentally falling off the isolation cover 4 during use.
[0029] Furthermore, a filter bag 5 is provided between the isolation cover 4 and the switch assembly 3. The upper and lower sides of the filter bag 5 abut against the isolation cover 4 and the switch assembly 3 respectively. Several water filtering holes 51 are distributed on the side wall and / or bottom of the filter bag 5. The filter bag 5 can isolate the residue, prevent the residue from clogging the drain outlet 22 and affecting the normal use of the drainer, and at the same time facilitate the user to collect and dispose of the residue.
[0030] Furthermore, the upper periphery of the filter bag 5 is provided with an outward flange 52. The outer side of the outward flange 52 is tightly fitted with the inner wall of the inner lower water shell 2, and the upper side of the outward flange 52 abuts against the isolation cover 4. The outward flange 52 can improve the structural strength of the funnel, while preventing larger residues from entering the lower water chamber 21 from the gap between the funnel and the inner lower water shell 2. It can also make it easier for the isolation cover 4 to apply a pushing force to the filter bag.
[0031] Furthermore, the bottom of the filter bag 5 is provided with a hollow cavity 53 corresponding to the switch assembly 3. The side of the hollow cavity 53 facing away from the switch assembly 3 protrudes towards the isolation cover 4, which can make the connection accuracy between the filter bag and the switch assembly 3 higher and the two are less likely to shift. At the same time, the user can more easily take out the filter bag through the protrusion of the hollow cavity 53 towards the isolation cover 4, which further facilitates cleaning the filter bag.
[0032] Furthermore, the outer lower water shell 1 and the inner lower water shell 2 are connected and fixed to each other by a threaded structure, which can achieve quick assembly and disassembly between the outer lower water shell 1 and the inner lower water shell 2.
[0033] Second embodiment:
[0034] See Figure 3 The difference between this embodiment and the first embodiment is that: the upper side of the isolation cover 4 of this drain device has a number of drain holes 42, and the outer side of the isolation cover 4 has a number of protruding ribs 43. The protruding ribs 43 are tightly fitted with the inner lower water shell 2, and adjacent protruding ribs 43 can form a drain gap. In this embodiment, the isolation cover 4 only serves to isolate residue, and water can pass normally through the surface of the isolation cover 4.
[0035] The remaining undescribed parts are the same as in the first embodiment and will not be repeated here.
[0036] The above embodiments are merely preferred embodiments of this utility model, and other implementations are also possible. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model, and all such equivalent modifications or substitutions are included within the scope set forth in the claims of this application.
