Description
Technical Field
[0001] The utility model relates to the technical field of dust box sealing, in particular to a dust box sealing structure. Background Art
[0002] With the rapid development of science and technology, more and more sweeping robots are entering users' homes, greatly improving the comfort and convenience of people's lives. When choosing to buy sweeping robots, users pay attention to the product's cost-effectiveness and ease of operation; therefore, products that reduce production costs and simplify operations can win the favor of more consumers.
[0003] The dust box of the sweeping robot is the core component of the cleaning system. It must not only have good dust collection performance, but also be convenient for users to clean the garbage and dust in the dust box.
[0004] Currently on the market, the dust box used in sweeping robots requires users to use both hands to pry open the dust box when cleaning the garbage and dust inside the dust box. The dust in the dust box will dirty the user's hands, and the user needs to specially clean the dust on his hands. Therefore, it is very inconvenient to use, the user experience is poor, and the sealing effect of this type of dust box is very poor, and the cost of use is high.
[0005] Therefore, the applicant proposes a dust box sealing structure to solve the above problems. Utility Model Content
[0006] In order to solve the deficiencies in the prior art, the utility model provides a dust box sealing structure.
[0007] The technical solution of the utility model is:
[0008] The utility model provides a dust box sealing structure, comprising an upper shell, a sealing ring and a lower shell, wherein the upper shell and the lower shell are hinged to each other to form a dust box, a locking assembly is provided at the non-hinged end of the lower shell, a sealing groove is provided on the contact surface between the upper shell and the lower shell, the sealing ring is arranged in the sealing groove, and a main rib matching the sealing groove is provided on the peripheral side of the top surface of the lower shell.
[0009] Furthermore, the locking assembly includes a locking seat arranged at the front end of the lower shell and a locking member movably arranged in the locking seat, a spring is arranged between the locking member and the inner bottom surface of the locking seat, and a locking hole is opened on the upper shell corresponding to the locking end of the locking member.
[0010] Furthermore, the inner side surface of the locking end of the locking piece is an inclined surface.
[0011] Furthermore, a secondary rib is provided in the sealing groove.
[0012] Furthermore, the sealing ring is made of EVA material.
[0013] Further, the upper shell and the lower shell are made of hard plastic material.
[0014] The beneficial effects achieved by the present utility model are as follows:
[0015] For a dust box sealing structure provided by the present utility model, a user can press a locking component with one hand to quickly unlock the dust box and rotate the dust box along its hinge end to open the dust box to clean the dust and garbage inside, which is convenient for the user to operate and the user's hands will not be contaminated with garbage and dust; at the same time, through the mutual contact and cooperation between the sealing ring on the upper shell and the main rib position on the lower shell, the whole circle interference can be achieved to realize a long-term and efficient sealing effect, and at the same time, the production and use costs can be reduced.

[0021] Figure 6 is Figure 5 An enlarged view of part C of Detailed Embodiments
[0022] For the convenience of those skilled in the art to understand the present utility model, the following clearly describes the detailed embodiments of the present utility model with reference to the drawings. Obviously, the described detailed embodiments are only the relatively preferred embodiments of the present utility model, rather than all the embodiments.
[0023] As Figures 1-6 shown, a dust box sealing structure of the present utility model includes an upper shell 1, a sealing ring 2 and a lower shell 3. The rear ends of the upper shell 1 and the lower shell 3 are hinged to each other to form a dust box. A locking component 4 for fixing and locking the upper shell and the lower shell 3 is provided at the front end of the lower shell 3. A sealing groove 11 surrounding the entire upper shell 1 is formed on the contact surface between the upper shell 1 and the lower shell 3. The sealing ring 2 is arranged in the sealing groove 11. The sealing groove 11 is used to limit the displacement of the sealing ring. A main rib position 31 matching the sealing groove 11 is provided on the circumferential side of the top surface of the lower shell 3; the main rib position 31 can be inserted and matched with the sealing groove 11 and cooperate with the sealing ring 2 to achieve the function of integral circle interference sealing.
[0024] The sealing ring 2 is made of materials including but not limited to EVA, TPU, etc., and is preferably made of EVA material; the EVA material has good elasticity and wear resistance, can provide good sealing performance, ensure that it is not easily damaged during long-term use, and at the same time has lower production cost.
[0025] A secondary rib position 12 is provided in the sealing groove 11; it is used to support the sealing ring and realize the function of restricting its displacement.
[0026] The locking assembly 4 includes a locking seat 41 provided at the front end of the lower housing 3 and a locking member 42 movably provided in the locking seat 41. A spring is provided between the locking member 42 and the inner bottom surface of the locking seat 41. A locking hole 13 is provided on the upper housing 1 corresponding to the locking end of the locking member 42; the elastic force of the spring is used to push up the locking member 42 so that its locking end cooperates with the locking hole to complete the locking state between the upper and lower housings; when pressing the locking member by hand, its locking end contacts and cooperates with the upper housing to complete the unlocking state between the upper and lower housings;
[0027] The inner side surface of the locking end of the locking member 42 is an inclined surface; it is convenient to complete the cooperation quickly.
[0028] The upper housing 1 and the lower housing 3 are preferably made of hard plastic material; to improve the service life.
[0029] In actual application, the user can press the locking assembly with one hand to quickly unlock the dust box and rotate it along its hinge end to open the dust box to clean the dust and garbage inside, which is convenient for the user to operate and the hands will not be contaminated with dust and garbage at the same time; at the same time, through the mutual contact and cooperation of the EVA sealing ring on the upper housing and the main rib position on the lower housing, the whole circle interference fit can be achieved to realize a long-term and efficient sealing effect, and at the same time, the production and use costs can be reduced.
[0030] The above-described embodiments of the present invention do not constitute a limitation to the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
