[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 5 , the utility model provides the following technical solutions:

[0027] Embodiment 1: In this embodiment, in order to solve the problems existing in the prior art, Figure 1-Figure 2 The following scheme is disclosed as shown, wherein the handle structure includes a handle position arranged on the sewage tank body 1, wherein the sewage tank upper cover 2 is installed at the top opening of the sewage tank body 1, and the top of the sewage tank body 1 includes an extension portion integrated with the box body, and the extension portion is wrapped around the sewage tank upper cover 2 to achieve a reinforcement-free connection between the sewage tank upper cover 2 and the sewage tank body 1. After most of the side surfaces of the sewage tank upper cover 2 are wrapped by the extension portion of the sewage tank body 1, the connection between the upper cover and the box body becomes very simple, and only needs to be placed directly. Due to the use of the extension portion, the user can directly take out the sewage tank body 1, the sewage tank upper cover 2 and the filter component 3 embedded in the upper cover for absorbing odor from the device by grasping and pulling the extension portion of the sewage tank body 1.

[0028] In order to further improve the practical effect of the above-mentioned scheme, the present embodiment also includes the following auxiliary scheme, wherein the extension portion and the sewage tank upper cover 2 are sealed by a rubber ring 4 distributed around the outer peripheral edge of the upper cover. This sealing means is relatively conventional, but it is precisely because the sewage tank upper cover 2 and the sewage tank body 1 adopt this new connection method through the extension portion that there is no need to adopt a more complicated connection or sealing structure between the upper cover and the box body, and buckle holes 5 are also opened on the left and right sides of the sewage tank upper cover 2, wherein the outer ends of the buckle holes 5 are not blocked by the sewage tank body 1. The purpose of designing the buckle holes 5 is to facilitate the user to choose according to their own needs, and to be able to take out the sewage tank upper cover 2 separately through the buckle holes 5 when the box body has the extension portion to wrap the upper cover for connection.

[0029] As an extension of the above embodiment, the invention is to further improve the efficiency of taking out the sewage tank when the box body is provided with an extension portion to wrap the upper cover, and solve the problem that too much sewage in the sewage tank causes a heavy load when the box body is taken out. Figure 2-Figure 3As shown, the hand grip is located in the extension area, and the hand grip is used to simultaneously pull out the sewage tank cover 2 and the sewage tank body 1 from the device. The hand grip includes a through hole 6 that is horizontally penetrated through the extension in the sewage tank body 1. After the extension in the sewage tank body 1 has the through hole 6 structure, the through hole 6 can significantly increase the resistance between the finger and the tank body when the user pulls the tank body with the hand grip, thereby effectively improving the efficiency of removing the sewage tank body 1.

[0030] The hand-holding position is also arranged in the sewage tank upper cover 2, and includes a groove structure 7 opened on the sewage tank upper cover 2. When the sewage tank upper cover 2 is installed on the sewage tank body 1, the groove structure 7 is covered by the through hole 6, wherein the groove structure 7 is used to accommodate the finger part passing through the through hole 6. As shown in the figure, the through hole 6 in a normal state covers the groove structure 7. Therefore, through the joint influence of the through hole 6 and the groove structure 7, the user can make the water tank and the upper cover take out process more labor-saving by passing the finger through the through hole 6 and against the inside of the groove structure 7 in the normal state of the sewage tank. It is only necessary to reserve a groove structure 7 with sufficient space in the upper cover during the production stage.

[0031] Embodiment 2: This embodiment is to further minimize the occupation of the internal space of the sewage tank cover 2 by the groove structure 7 under normal use on the basis of achieving the effects of the above embodiments. The specific scheme can also refer to Figure 2-Figure 3 The groove structure 7 is separated from the internal space of the sewage tank cover 2 by a partition. The volume of the groove structure 7 is variable and the initial state is a non-penetrating side wall of the sewage tank cover 2. The internal volume change of the groove structure 7 is realized by the state conversion of the partition. The partition is composed of a partition 8 of elastically deformable rubber material. By designing the groove structure 7 to be variable in volume, it can be achieved that under normal conditions, the groove structure 7 occupies a very small space and remains sealed, and when the sewage tank needs to be drawn out, the groove structure 7 is expanded in a short time by applying force of fingers to facilitate stable operation of the user. The structure is simple and more practical. At the same time, the partition 8 of rubber material can more effectively ensure the sealing effect, which is suitable for working environments where the interior of the sewage tank is often fully loaded. Even if the space of the groove structure 7 is passively expanded, the internal sewage will not overflow from the groove structure 7.

[0032] Embodiment 3: This embodiment discloses a solution different from the above embodiment, the main difference is reflected in the interlayer structure, refer to Figure 4As shown, the partition includes a hard partition 8 whose outer surface is covered with a rubber sheet. In the initial state, the partition 8 covers the inner end of the groove structure 7 from the inner end and maintains the seal through the deformation of the rubber sheet. The partition 8 is elastically rotated and installed at the inner end of the groove structure 7 by a spring. The partition 8 is rotated at the top end of the groove structure 7, and the maximum rotation angle is 30°. The hard partition 8 will deflect accordingly after being subjected to force, and support the fingers after deflecting to a fixed angle, thereby increasing the accommodating space of the groove structure 7 to facilitate the accommodation and insertion of fingers. The disadvantage is that the cost is higher and additional sealing means are required, such as the layer structure and ring structure of the rubber deformable seal covered on the partition 8 disclosed in this embodiment. The advantage is that compared with the flexible structure, the hard partition 8 has a more stable support force for the fingers after being rotated and unfolded, which is more suitable for the design requirements of the hand-holding position of the large-capacity sewage tank 1.

[0033] Embodiment 4: In this embodiment, a different installation method of the partition 8 from that of the embodiment 3 is disclosed, such as Figure 5 As shown, the partition 8 is rotatably installed at the bottom end of the groove structure 7. At the same time, the top of the outer surface of the partition 8 and the top wall of the inner end of the groove structure 7 are both arc-shaped, switching from upper rotation to lower rotation. The disadvantage is that during operation, the finger may pass through the groove structure 7 and contact the inside of the sewage tank cover 2, causing some dirt to be stained on the finger. The advantage is more obvious, which can make the finger more stably buckled in the sewage tank and the cover, and the operation is more stable.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
