Description

Technical Field

[0001] This utility model relates to a connection structure between the cover and the body of a cleaning machine. Background Technology

[0002] A cleaning machine is suitable for cleaning small items, such as baby bottles and bottle accessories. Cleaning machines are usually designed with an open top, and the cleaning chamber is opened by opening the top cover. In order to improve the sealing performance of the cover, some sealing rings are usually set on the cover. The sealing effect of the sealing rings prevents water from seeping out from the connection between the cover and the machine body when the cleaning machine is working. However, the use of sealing rings has problems such as sealing ring aging and sealing ring falling off.

[0003] Therefore, it is necessary to make further improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a connection structure between the cover and the body of a cleaning machine. This connection structure solves the sealing problem at the connection between the cover and the body, and eliminates the need for sealing rings.

[0005] To achieve the above objectives, this utility model provides a connection structure between the cover and the body of a cleaning machine. The body has a cleaning chamber with an upper opening. The cleaning chamber has a concave step along the inner edge of its upper opening. The cover is rotatably connected to the body and can rotate relative to the body to close the upper opening. The inner side of the cover has a convex step that mates and seals with the concave step. The outer side of the cover has an inwardly recessed handle groove.

[0006] In one or more embodiments, the handle groove is distributed along the left side, front side and right side of the cover.

[0007] In one or more embodiments, a water-guiding slope is provided on the rear side of the concave step, and the rear end of the cover is rotatably connected to the body.

[0008] In one or more embodiments, a pivot seat is provided on the water guide slope, and the cover is rotatably connected to the pivot seat.

[0009] In one or more embodiments, the pivot seat is provided with a damper and a pivot shaft, the damper is provided with a non-circular damping shaft, the damping shaft and the pivot shaft are respectively located at both ends of the pivot seat, and the cover is respectively connected to the damping shaft and the pivot shaft.

[0010] In one or more embodiments, the pivot seat is provided with a mounting recess and a pressure cap, at least a portion of the damper is embedded in the mounting recess, and the pressure cap is fixed to the pivot seat by screws and holds the damper.

[0011] In one or more embodiments, the mounting recess and the pressure cap are provided with positioning ribs, and the damper is provided with a groove that mates with the positioning ribs.

[0012] In one or more embodiments, the pivot shaft and the gland are integrally formed.

[0013] Compared with the prior art, the present invention has the following advantages: by combining concave and convex steps, the connection between the body and the cover is strengthened, and water is less likely to seep out from the connection between the body and the cover; in addition, by setting a handle groove on the outer side of the cover, the aesthetics are higher than those of the traditional handle structure.

Detailed Implementation

[0015] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0016] See appendix Figure 1-3 This application provides a connection structure between the cover and the body of a cleaning machine. The body 1 has a cleaning chamber 2 with an upper opening. The cleaning chamber 2 has a recessed step 3 along the inner edge of its upper opening. The cover 4 is rotatably connected to the body 1 and can rotate relative to the body 1 to close the upper opening. The inner side of the cover 4 has a raised step 5 that mates with and seals against the recessed step 3. The outer side of the cover 4 has an inwardly recessed handle groove 6. After the cover is closed, the engagement of the raised step 5 and the recessed step 3 improves the sealing at the connection between the cover and the body, ensuring that water does not leak out. To ensure the sealing effect, the depth of the recessed step 3 is 5mm-15mm, preferably 10mm. In addition, the handle groove provides a gripping function for the user to open the cover. The handle groove makes full use of the outer side space of the cover, so there is no need to set a handle on the cover separately.

[0017] The handle groove 6 is distributed along the left, front and right sides of the cover 4, so that the handle groove can be better integrated into the cover structure. Compared with the setting of a handle groove on a single side, the abruptness is lower and the design is more natural.

[0018] The rear side of the concave step 3 is provided with a water guide slope 7. The rear end of the cover 4 is rotatably connected to the body 1. The operation of the cleaning machine requires spraying, drying and other processes. If there is water on the inner side of the cover, when the cover is opened, the water droplets on the cover will flow downward under the action of gravity. Therefore, the water will drip onto the water guide slope and be introduced into the cleaning chamber 2 by the water guide slope.

[0019] A pivot seat 8 is provided on the water guide slope 7, and the cover 4 is rotatably connected to the pivot seat 8. The pivot seat is set on the water guide slope so that all the water dripping from the cover is caught by the water guide slope and guided back into the cleaning chamber.

[0020] See appendix Figure 4 and 5 The pivot seat 8 is provided with a damper 9 and a pivot shaft 10. The damper 9 is provided with a non-circular damping shaft 91. The damping shaft 91 and the pivot shaft 10 are respectively located at both ends of the pivot seat 8. The cover 4 is connected to the damping shaft 91 and the pivot shaft 10 respectively. The damper can provide a buffer when the cover 4 is opened and closed, so that the cover can slowly contact the body 1 when closed, avoiding a loud closing noise. When the user opens the cover forcefully, the damper can also prevent the user from using too much force and damaging the cover.

[0021] The pivot seat 8 is provided with a mounting recess 11 and a pressure cap 12. At least a portion of the damper 9 is embedded in the mounting recess 11. The pressure cap 12 is fixed to the pivot seat 8 by screws and presses the damper 9. The damper is firmly fixed to the pivot seat 8 by the cooperation of the mounting recess 11 and the pressure cap 12. The pivot shaft 10 and the pressure cap 12 are integrally formed.

[0022] The mounting recess 11 and the pressure cover 12 are provided with positioning ribs 13, and the damper 9 is provided with a groove 14 that cooperates with the positioning ribs. The cooperation between the positioning ribs 13 and the groove 14 makes the damper more stable after installation and also plays a role in positioning and installation.

[0023] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. All equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
