Description

Technical Field

[0001] The utility model relates to the field of daily necessities, in particular to a crotchless water tank filter bag. Background Art

[0002] As people's living standards improve and their environmental awareness increases, they attach great importance to the classification, collection and treatment of kitchen waste. A filter woven with fine threads is placed in the dishwashing sink. When washing dishes, clean water will flow away and kitchen waste will be filtered out. This not only delays the odor of kitchen waste, but also keeps the sewer clean and hygienic.

[0003] The filter bag needs to be stably sleeved in the water tank, and a cuff needs to be woven at the bag opening of the filter bag or an elastic ring needs to be set at the bag opening so that the filter bag can be radially tightened on the water tank; whether the cuff is woven (see the prior patent, patent number: 201220746916.8) or the elastic ring is set (see the prior patent, patent number: 201510848572.X), the production process of the filter bag will be increased. Taking the cuff weaving at the bag opening as an example, when a circular loom was used to weave a mesh bag in the past, after weaving a certain length of the mesh bag, the mechanism for weaving the cuff had to be switched. After the cuff was woven, the cuff mechanism was stopped, and the circular loom weaved the cylindrical mesh bag normally. For this kind of mesh bag with a cuff, the circular loom needs to be repeatedly switched during the weaving process, the weaving method is relatively cumbersome, the defective rate is relatively high, the energy consumption and the loss of knitting needles are high, and most importantly, it is not convenient for the subsequent process to develop automated production. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a water tank filter bag without cuffs, so as to solve the technical problem that the production efficiency and cost of the filter bag are affected by the separate cuffs woven on the filter bag or the elastic rings arranged at the bag opening.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] Provided is a crotchless water tank filter bag, comprising:

[0007] The mesh bag body is a tubular fabric, one end of which is a bag opening and the other end is closed as a bag bottom;

[0008] At least one elastic line is woven in the fabric layer of the mesh bag body, one end of the elastic line is connected to the bag bottom, the other end of the elastic line is connected to the bag opening, and the elastic line is distributed in a spiral shape in the length direction of the mesh bag body.

[0009] Furthermore, the bottom of the mesh bag body is sealed by sewing with yarn or by hot-melt welding.

[0010] Furthermore, the bottom of the mesh bag body is radially gathered to form a closed opening.

[0011] Further, the lower end of the mesh bag body is wound and bonded with a film to form a closed drawstring at the bottom of the bag.

[0012] Further, the elastic cord is any one of spandex covered yarn, spandex filament, polyester filament, and nylon filament.

[0013] Further, the diameter of the elastic cord is 30 - 100D.

[0014] Further, the yarn material of the mesh bag body is polyester filament.

[0015] Further, the fabric structure of the mesh bag body is plain weft knitting.

[0016] The beneficial effects of the present utility model are:

[0017] For the non - flanged sink filter bag of the present utility model, by arranging a spiral elastic cord in the mesh bag, when the filter bag is sleeved on the sink, the spiral elastic cord can provide a radial contraction force for the filter bag, and the filter bag can radially contract on the outer wall of the sink.

[0018] The elastic cord is evenly dispersed and added to the fabric structure of the filter bag. In this way, it not only does not affect the original use function, but also enhances the overall knitting strength of the sink filter net, and at the same time improves the load - bearing capacity of the sink filter net.

[0019] The elastic cord is woven in together by the method of spiral weft knitting during the knitting process of the mesh bag. When knitting on a circular loom, the knitting mechanism needs to be switched. The mesh bag body is normally knitted by the circular loom, and the elastic cord enters in a weft knitting manner, running through the entire knitting process of the mesh bag, improving the knitting efficiency of the entire mesh bag, increasing the finished product rate, and reducing consumption and increasing efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model.

[0026] This application provides a filter bag for a sink without a drawstring. The following will be described in detail respectively. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of this application. And in the following embodiments, each embodiment has its own emphasis. For parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0027] To solve the technical problem in the prior art that separately knitting a drawstring on the filter bag or setting an elastic ring at the bag mouth affects the production efficiency and cost of the filter bag, an embodiment of this application provides a filter bag for a sink without a drawstring. The following will be elaborated in detail.

[0028] Embodiment 1

[0029] As Figure 1 shown, a filter bag for a sink without a drawstring includes

[0030] a mesh bag body 1, the mesh bag body 1 is a tubular fabric, one end is the bag mouth, and the other end is closed as the bag bottom;

[0031] a stretch cord 2, the stretch cord 2 is woven into the fabric layer of the mesh bag body 1, one end of the stretch cord 2 is connected to the bag bottom, the other end of the stretch cord 2 is connected to the bag mouth, and the stretch cord 2 is spirally distributed in the length direction of the mesh bag body 1.

[0032] In this embodiment, the bag bottom of the mesh bag body 1 is closed by sewing with yarn or by heat welding.

[0033] The stretch cord 2 is any one of spandex covered yarn, spandex filament, polyester filament, and nylon filament. In this embodiment, the stretch cord 2 is spandex covered yarn.

[0034] As a preferred implementation manner of this embodiment, in this embodiment, the wire diameter of the stretch cord 2 is 30 - 100D.

[0035] In this embodiment, the fabric structure of the mesh bag body 1 is a plain weft knitting structure, which is formed by a circular knitting machine, and the stretch cord 2 is woven into the plain weft knitting structure in a weft knitting manner.

[0036] In this embodiment, the yarn material of the mesh bag body 1 is polyester filament.

[0037] The number of elastic lines 2 is determined by the manufacturer according to the radial contraction force required by the mesh bag. The number of elastic lines 2 can be set to two or more. The more elastic lines 2 there are, the greater the radial contraction force that can be provided.

[0038] The crotchless water tank filter bag of this embodiment is a cylindrical structure as a whole. When processing this filter bag, it is completed by a circular loom. A set of weft-knitted elastic wire 2 mechanisms are added to the circular loom. The elastic wire 2 is woven into the mesh bag during the weaving process. A long cylindrical mesh bag is first woven, and then it is cut according to the predetermined length of the water tank filter bag. The cut filter bag has its bottom sealed.

[0039] In the production process of the sink filter bag, there is no need to weave the cuffs on the cylindrical mesh bag. The mesh bag processing speed is very efficient, which improves the weaving efficiency of the entire mesh bag. Since the spiral elastic line 2 is arranged in the mesh bag, when the filter bag is sleeved on the sink, the spiral elastic line 2 can provide radial contraction force for the filter bag, and the filter bag can be radially contracted on the outer wall of the sink.

[0040] When the sink filter bag is used in the sink, it is first placed in the sink, and then the upper end of the filter bag is turned upside down in the sink. The filter bag turned upside down on the sink fits on the outer wall of the sink, and the spiral elastic line 2 on this part of the mesh bag contracts radially to achieve radial fitting of the filter bag on the sink.

[0041] Embodiment 2

[0042] The present application provides another cuffless water trough filter bag. The cuffless water trough filter bag of this embodiment is based on the filter bag in the first embodiment, and the differences are described in detail below.

[0043] like Figure 2 As shown, in this embodiment, the bottom of the mesh bag body 1 is radially gathered to form a closed opening.

[0044] That is, the entire water tank filter bag is in the shape of a cone, the bag opening at the upper end of the filter bag is a cut opening, and the lower end is a closed tie opening.

[0045] The drawstring at the bottom of the mesh bag can still be sewn with the yarn or heat-melt welded as mentioned above.

[0046] As a preferred implementation of this embodiment, the lower end of the mesh bag body 1 is wound and bonded with a film 3 to form a closed opening at the bottom of the bag.

[0047] In this embodiment, the film 3 adopts the currently available cellulose acetate film.

[0048] The bottom of the mesh bag is sealed with film 3. Compared with sewing and welding, sealing with film 3 can be more efficient and improve the production efficiency of the filter bag.
