Description

Technical Field

[0001] The present invention relates to the technical field of inflatable mattresses, and particularly to an inflation controller and an inflatable mattress. Background Art

[0002] For intelligent inflatable mattresses, intelligent control systems are required, and for intelligent mattress controllers, air pipes and auxiliary devices for pumping air into the inner cavity of the mattress airbag are needed. The existing controllers have the following deficiencies:

[0003] 1) The holes on the controller through which the air supply pipes (for connecting the controller and the mattress airbag) pass are round holes. Since the air pipes are relatively long and there are connecting parts such as joints and anti-loosening clamps on the air pipes, the installation of the air pipes is inconvenient.

[0004] 2) The controller does not have a noise reduction structure, so that the motor inside the controller will generate relatively high-decibel noise during operation, affecting the comfort of product use.

[0005] 3) When the controller controls the deflation of the mattress airbag, air will be discharged at the solenoid valve air discharge port inside the controller, and this exhaust process will cause relatively loud noise, affecting the comfort of product use. Summary of the Invention

[0006] The purpose of the present invention is to provide an inflation controller and an inflatable mattress to solve the technical problem of inconvenient installation of air pipes in the prior art.

[0007] To achieve this purpose, the present invention adopts the following technical solutions:

[0032] As Figures 1 to 4 shown, the present invention provides an inflation controller, which includes a housing 10 and a control component disposed within the housing 10. The control component includes an inflation solenoid valve 21, an inflation pump (not shown in the figure), an inflation motor (not shown in the figure), and a deflation solenoid valve 22. The inflation motor is used to drive the inflation pump. The inflation pump is communicated with the inflation solenoid valve 21. The inflation solenoid valve 21 is communicated with the air inlet of the mattress through an inflation air pipe 31. The air outlet of the mattress is communicated with the deflation solenoid valve through an air outlet pipe. The inflation controller can inflate the mattress airbag through the inflation solenoid valve 21 and the inflation air pipe 31, and the gas in the mattress airbag can be discharged through a deflation air pipe 32 and the deflation solenoid valve 22.

[0033] In this embodiment, the housing 10 includes an upper shell 11, a lower shell 12 and a front cover plate 13. The upper shell 11 and the lower shell 12 are detachably connected. The upper shell 11 and the lower shell 12 enclose a receiving cavity with a front opening. The control assembly is disposed in the receiving cavity and fixed to the lower shell 12. First positioning structures are provided on both the upper shell 11 and the lower shell 12 at the front opening. The front cover plate 13 can be closed at the front opening through the first positioning structures. A plurality of notches 131 are formed in the lower edge of the front cover plate 13, and the notches 131 can accommodate air pipes. The air pipes include the above-mentioned inflation air pipe 31 and deflation air pipe 32. When assembling the controller, first connect the inflation air pipe 31 to the inflation solenoid valve 21 and connect the deflation air pipe 32 to the deflation solenoid valve 22. Then position the lower part of the front cover plate 13 on the first positioning structure of the lower shell 12, and at the same time place the air pipes one by one in the plurality of notches 131 of the front cover plate 13. Finally, connect the upper shell 11 and the lower shell 12, and ensure that the upper part of the front cover plate 13 cooperates with the first positioning structure of the upper shell 11. By setting the housing 10 as a split type and providing the notches 131 on the front cover plate 13, the air pipes can be fixed while assembling the front cover plate 13, and the assembly is simple. Preferably, the notches 131 are semicircular, which can better match the air pipes.

[0034] In this embodiment, one of a plurality of fixing grooves 121 and a plurality of fixing posts 111 is provided on the lower shell 12, and the other of the plurality of fixing grooves 121 and the plurality of fixing posts 111 is provided on the upper shell 11.

[0035] Two spaced-apart first limiting protrusions 40 are provided on the inner walls of both the upper shell 11 and the lower shell 12 at the front opening. The two first limiting protrusions 40 are the above-mentioned first positioning structures. The edge portion of the front cover plate 13 can be inserted between the two first limiting protrusions 40. The above-mentioned positioning of the front cover plate 13 on the first positioning structure of the lower shell 12 specifically means inserting the lower edge portion of the front cover plate 13 between the two first limiting protrusions 40 of the lower shell 12. In addition, when connecting the upper shell 11 and the lower shell 12, the upper edge portion of the front cover plate 13 should be limited between the two first limiting protrusions 40 of the upper shell 11, so that after the upper shell 11 and the lower shell 12 are connected, the front cover plate 13 can be fixed at the same time.

[0036] In this embodiment, the housing 10 further includes a rear cover plate 14. The accommodation cavity formed by the upper shell 11 and the lower shell 12 further has a rear opening, and the rear cover plate 14 is closed at the rear opening. By adding the rear cover plate 14, the molding process of the upper shell 11 and the lower shell 12 can be simplified. Specifically, two second limiting protrusions 50 distributed at intervals are provided on the inner walls of the upper shell 11 and the lower shell 12 at the rear opening, and the edge portion of the rear cover plate 14 can be inserted between the two second limiting protrusions 50. Before connecting the upper shell 11 and the lower shell 12, the lower edge portion of the front cover plate 13 should be located between the two first limiting protrusions 40 of the lower shell 12, and the lower edge portion of the rear cover plate 14 should be located between the two second limiting protrusions 50 of the lower shell 12; when connecting the upper shell 11 and the lower shell 12, it should be ensured that the upper edge portion of the front cover plate 13 is limited between the two first limiting protrusions 40 of the upper shell 11, and at the same time, it should be ensured that the upper edge portion of the rear cover plate 14 is located between the two second limiting protrusions 50 of the upper shell 11, so that after the upper shell 11 and the lower shell 12 are connected, the front cover plate 13 and the rear cover plate 14 can be fixed at the same time.

[0037] Furthermore, a sound absorption layer is provided on the inner wall of the housing 10, so that when the inflation motor works, a part of the noise can be absorbed, the noise of the controller can be reduced, and the use comfort of the product can be improved. Preferably, the material of the sound absorption layer is sound absorption cotton.

[0038] Furthermore, referring to Figure 4 , an air release channel 221 is provided in the air release solenoid valve 22. In this embodiment, the air release channel 221 is set as a curved channel, so as to increase the path of the gas (as shown by the arrow A in Figure 4 ), reduce the noise generated during air release, and further improve the use comfort of the product. Preferably, the curved channel is formed by at least two bends.
