DETAILED DESCRIPTION

[0034] Combine the following Figure 1-11 The utility model is described in detail.

[0035] A foaming device 10 includes a base 20, wherein the base 20 is provided with a bubble inlet 201, a bubble outlet and a bubble inlet channel connecting the bubble inlet 201 and the bubble outlet, a rotatable bubble outlet joint 30 is provided at the bubble outlet, the bubble outlet joint 30 is provided with a bubble outlet channel connected to the bubble inlet channel, an outer facade of the bubble outlet joint 30 is provided with a main bubble outlet 301 connected to the bubble outlet channel, and an outer facade opposite to the main bubble outlet 301 is provided with at least one secondary bubble outlet 302 connected to the bubble outlet channel; and further includes a motor 40, the output end of the motor 40 is transmission-connected to the bubble outlet joint 30, and is used to drive the bubble outlet joint 30 to rotate relative to the base 20.

[0036] When the bubble outlet joint 30 is rotated at the same angle, compared with the bubble outlet joint only equipped with a single bubble outlet, the bubble outlet joint increases the pot surface area covered by the foam sprayed by the bubble outlet joint 30 through the synergistic effect of the main bubble outlet 301 and the secondary bubble outlet 302, thereby improving the wall moistening effect.

[0037] In this embodiment, the base 20 is provided with a mounting port 202 connected to the bubble inlet channel, and also includes a transmission shaft 50, one end of the transmission shaft 50 is sealed and rotatably adapted to the mounting port 202, the other end of the transmission shaft 50 is sealed and rotatably adapted to the bubble outlet, one end of the transmission shaft 50 is connected to the output end of the motor 40, the transmission shaft 50 is provided with a bubble outlet joint 30, and the transmission shaft 50 is provided with a bubble passage connecting the bubble inlet channel and the bubble outlet channel. Further, as Figure 8 As shown, the foaming joint 30 is detachably connected to the other end of the transmission shaft 50. When in use, based on the structural advantage of the foaming joint 30 being installed from bottom to top, when the foaming joint 30 is removed, the foaming device 10 is used as a foaming device with the foam fixedly facing downward, and two foaming modes can be easily switched. At the same time, compared with other non-rotating foaming and fixed downward foaming devices on the market, due to the addition of an air pump, the foaming amount is greater, and the splash-proof and odor-isolating effects are better.

[0038] In this embodiment, a first overlapping portion 801 extending radially outward is provided on an outer surface of one end of the transmission shaft 50 , and a second overlapping portion 802 for abutting against the first overlapping portion 801 is provided at the bottom of the installation opening 202 .

[0039] In this embodiment, the foaming directions of the main foam outlet 301 and the secondary foam outlet 302 have different angles with the axis of the foam outlet connector 30, and the main foam outlet 301 and the secondary foam outlet 302 have foaming extension sections of different lengths. Among them, the foaming directions of the main foam outlet 301 and the secondary foam outlet 302 have angles with the axis of the foam outlet connector 30 of ∠1 and ∠2, respectively, and the foaming extension section lengths of the main foam outlet 301 and the secondary foam outlet 302 are L1 and L2, respectively. Figure 6 As shown, it is convenient for the user to replace the bubble outlet joint 30 with different bubble outlet angles and bubble outlet extension sections according to actual usage.

[0040] In this embodiment, if the area swept by the primary bubble outlet 301 and the secondary bubble outlet 302 of the bubble outlet joint 30 during the rotation cycle needs to cover the entire pot surface, that is, to achieve 360° full coverage of the pot surface by foam, the number of secondary bubble outlets 302 and the rotation angle of the bubble outlet joint 30 meet the following conditions:

[0041] 360° / (n+1)<α≤360° / n

[0042] Wherein, n is the number of the secondary bubble outlets 302 , α is the rotation angle of the bubble outlet joint 30 , and the angle between two adjacent bubble outlets is not greater than α. Therefore, when the rotatable angle of the bubble outlet joint 30 is between 180°<α≤360°, a secondary bubble outlet 302 needs to be set, and the secondary bubble outlet 302 can be arranged at any angle position; when the rotatable angle is 120°<α≤180°, two secondary bubble outlets 302 need to be set, and the angle between adjacent bubble outlets is not greater than α; when the rotatable angle is 90°<α≤120°, three secondary bubble outlets 302 need to be set, and the angle between adjacent bubble outlets is not greater than α, and so on. The number of secondary bubble outlets 302 is increased based on the rotatable angle. Generally, a maximum of two secondary bubble outlets 302 can meet the rotational foaming requirements of most smart toilets. At the same time, because the increase in the number of secondary bubble outlets 302 is not conducive to part mold opening and molding, the secondary bubble outlets 302 can be assembled onto the bubble outlet joint 30 in combination with actual production process conditions.

[0043] In this embodiment, Fig. 9As shown, the rotation angle of the bubble outlet joint 30 is 120°<α≤180°. Based on the above analysis, it can be obtained that the bubble outlet joint needs to be provided with two secondary bubble outlets 302, and the angles between the main bubble outlet 301 and the secondary bubble outlet 302 are ∠A and ∠B respectively, and the angle between the secondary bubble outlets 302 is ∠C. Therefore, ∠A, ∠B, ∠C and the rotation angle α of the bubble outlet joint 30 need to simultaneously satisfy ∠A<α, ∠B<α and ∠C<α.

[0044] In this embodiment, Figure 4-5 As shown, the transmission shaft 50 is provided with a first connection portion 601, and the blister connector 30 is provided with a second connection portion 602 that is clamped to the first connection portion 601. The first connection portion 601 is a buckle, and the second connection portion 602 is a clamping groove. The transmission shaft 50 is provided with a first positioning portion 701, and the blister connector 30 is provided with a second positioning portion 702 that is adapted to the first positioning portion 701. The first positioning portion 701 is a convex portion, and the second positioning portion 702 is a concave portion.

[0045] In this embodiment, a gland 90 is further included, the gland 90 is fixedly connected to the base 20, the motor 40 is fixedly connected to the gland 90, and the gland 90 is provided with a through hole 901 for penetrating the output end of the motor 40. When the gland 90 is connected to the base 20, there is a small gap between the gland 90 and the transmission shaft 50, so that the gland 90 prevents the transmission shaft 50 from being separated from the base 20 while ensuring the normal rotation of the transmission shaft 50.

[0046] In this embodiment, Figure 2 As shown, the bubble inlet 201 is connected to a bubble inlet device, which includes a bubble inlet joint 100, one end of which is provided with an air inlet 1001 and a liquid inlet 1002, the other end of which is sealed and connected to the bubble inlet 201, and a bubbler 110 is provided in the bubble inlet joint 100. The air inlet 1001 is connected to the air pump, and the liquid inlet 1002 is connected to the foaming liquid. The provision of the air inlet 1001 will increase the foaming amount, and the splash-proof and odor-isolating effects will be better.

[0047] A toilet, such as Figure 10-11 As shown, it includes a ceramic body 120, the ceramic body 120 is provided with a cover device, and the base of the cover device is provided with the foaming device 10 as described above.

[0048] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable those skilled in the art to understand the content of the utility model and implement it, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
