Description

Technical Field

[0001] The present invention relates to the technical field of foaming devices, and in particular to a foaming device. Background Art

[0002] In daily life, especially when using daily chemical products such as facial cleansers, shower gels, shampoos, etc., it is often necessary to mix and foam liquids and gases and use them in a foamy state to achieve better cleaning and skin care effects and make them more convenient to use.

[0003] The existing foaming devices are mainly divided into two categories according to their foaming principles: one is to introduce high-pressure gas into and dissolve it in the liquid. At the moment the liquid containing the high-pressure gas is discharged from the container, the pressure drops sharply, the gas is released from the liquid, and foam is formed. The high-pressure gas is generally supplied through a high-pressure aerosol can, or the liquid containing the high-pressure gas is stored in a high-pressure tank. However, the storage, transportation and carrying of high-pressure aerosol cans and high-pressure tanks are inconvenient, and there are safety hazards such as flammability and explosion, which seriously limit the widespread application of high-pressure foaming devices; the other is to mix the gas and liquid at normal pressure and form foam through multiple mixing and stirring. Generally, in order to fully mix the gas and liquid at normal pressure, the gas and liquid need to pass through multiple filters in sequence. If multiple filters are installed in the foaming device, this will undoubtedly make the structure of the foaming device very complicated, the assembly is extremely difficult, and the equipment is large in size, which is not convenient for widespread use of the equipment.

[0004] In order to solve the above problems, this application is specially proposed. Summary of the Invention

DETAILED DESCRIPTION

[0032] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0033] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0034] like Figures 1 to 10 As shown, a foaming device includes a foaming chamber 1 and a chamber cover 2 covering the foaming chamber 1, wherein the foaming chamber 1 is hollow inside, and the foaming chamber 1 and the chamber cover 2 covering the foaming chamber 1 together form a hollow cavity;

[0035] The foaming device is provided with a first input port 14, a second input port 15 and a foaming port 16, which are respectively connected to the cavity. External gas and liquid can enter the cavity through the first input port 14 and the second input port 15 respectively, and are discharged through the foaming port 16 after foaming in the cavity.

[0036] At least one of the first foaming structure 11, the second foaming structure 12 and the third foaming structure 13 is disposed in the cavity;

[0037] The first foaming structure 11 includes a plurality of first foaming teeth 111 arranged in sequence, the first foaming teeth 111 are connected to the foaming chamber 1, and tooth-shaped through holes are provided on the first foaming teeth 111. The liquid and gas in the cavity can be mixed and foamed through the tooth-shaped through holes on each of the first foaming teeth 111 in sequence and then discharged through the foaming port 16.

[0038] Further, such as Figures 7-8 As shown, the first foaming teeth 111 are arranged in an arc shape on the foaming chamber 1, and the first foaming structure 11 includes a plurality of concentrically arranged first foaming teeth 111. Arranging the first foaming teeth 111 in an arc shape can increase the length of the first foaming teeth 111 and increase the foaming capacity of the foaming device.

[0039] Furthermore, one side of the first foaming tooth 111 is connected to the foaming chamber 1 , and a tooth-shaped through hole is provided on the opposite side.

[0040] Furthermore, if Figure 6 As shown, the first foaming structure 11 further includes a plurality of second foaming teeth 21 , which are arranged on the bin cover 2 , one side of the second foaming teeth 21 is connected to the bin cover 2 , and a tooth-shaped through hole is arranged on the opposite side.

[0041] Preferably, Figure 6 As shown, the second foaming teeth 21 are arranged in an arc shape on the compartment cover 2, and the first foaming structure 11 includes a plurality of concentrically arranged second foaming teeth 21.

[0042] like Figure 4 As shown, when the bin cover 2 and the foaming bin 1 are assembled, the first foaming teeth 111 and the second foaming teeth 21 are intertwined and engaged with each other, and an "S"-shaped channel is formed in the foaming device through the first foaming teeth 111 and the second foaming teeth 21. The liquid and gas in the cavity pass through the tooth-shaped through holes on the first foaming teeth 111 and the second foaming teeth 21 in turn along the "S"-shaped channel, and are fully mixed and foamed before being discharged through the foaming port 16. The setting of the "S"-shaped channel can greatly improve the uniformity of the mixing of liquid and gas and improve the foaming effect.

[0043] The present application sets the first foaming structure 11 in the foaming device, and allows the gas and liquid in the foaming device to pass through the multiple first foaming teeth 111 and the second foaming teeth 21 in the first foaming structure 11 in turn, and achieves the purpose of stirring and mixing the liquid and gas in the foaming device through the tooth-shaped through holes on the first foaming teeth 111 and the second foaming teeth 21 to foam them. It not only has a simple structure, small size, and easy assembly, but also avoids the use of high-pressure aerosol cans and high-pressure tanks, so that the foaming device described in the present application is highly safe and easy to store, transport and carry.

[0044] As some embodiments of the present application, the first foaming teeth 111 can be integrally formed with the foaming bin 1; the second foaming teeth 21 can be integrally formed with the bin cover 2, so that the first foaming teeth 111 and the second foaming teeth 21 do not need to be installed, further reducing the number of parts of the foaming device and simplifying the assembly steps of the foaming device.

[0045] Furthermore, a second foaming structure 12 is provided in the cavity, and the second foaming structure 12 includes a guide portion 122 and a retaining wall 123. The guide portion 122 is arranged in a trumpet shape at the outlet end of the first foaming structure 11. The guide portion 122 opens at one end close to the first foaming structure 11 and tightens at one end away from the first foaming structure 11 to form an inlet 121. A retaining wall 123 is provided on the side of the inlet 121 away from the first foaming structure 11, and an outlet 124 is provided on both sides of the retaining wall 123. The foam discharged from the first foaming structure 11 enters the inlet 121 under the guidance of the guide portion 122, and then flows out from the inlet 121. It is blocked and guided by the retaining wall 123 and flows out through the outlet 124, thereby achieving the purpose of further mixing and foaming.

[0046] Furthermore, the retaining wall 123 has an arc-shaped structure, and the retaining wall 123 is arched toward the side close to the inlet 121 , so that the foam flowing out of the inlet 121 is easily blocked and guided by the retaining wall 123 and flows out through the outlet 124 .

[0047] Furthermore, a third foaming structure 13 is provided in the cavity, and the third foaming structure 13 is located on the side of the retaining wall 123 away from the inlet 121. The third foaming structure 13 includes a plurality of "Y"-shaped guide members 131, and the guide members 131 are distributed at intervals to form a flow channel 132 between two adjacent guide members 131.

[0048] Furthermore, the third foaming structure 13 includes a plurality of annularly arranged "Y"-shaped flow guides 131. The ends of the two forked branches of the flow guide 131 are referred to as the heads of the "Y"-shaped flow guide 131, and the other ends are referred to as the tails of the "Y"-shaped flow guide 131. The heads of the flow guides 131 face the center of the circle and are arranged in an arc shape on the foaming chamber 1.

[0049] Furthermore, the foaming bin 1 includes a bottom surface and side walls arranged around the bottom surface. An inner bin 10 is provided on the bottom surface of the foaming bin 1. The inner bin 10 shares the same bottom surface with the foaming bin 1. The inner bin 10 also has an inner bin wall 101. The inner bin wall 101 cooperates with the side wall of the foaming bin 1 to divide the internal space of the foaming bin 1 into two parts. One part is the inner space of the inner bin 10, called the first space, and the other part is the space between the inner bin wall 101 of the inner bin 10 and the side wall of the foaming bin 1, called the second space.

[0050] Furthermore, the first input port 14, the second input port 15, the first foaming structure 11, the second foaming structure 12, the third foaming structure 13, and the foaming outlet 16 are all arranged in the first space, and the assembly structure of the foaming bin 1, the bin cover 2 and other components are all arranged in the second space. In this way, the foaming structure and the assembly structure of the foaming device can be separated to prevent the two from affecting and contaminating each other, and to improve the sealing performance of the foaming device.

[0051] As some embodiments of the present application, the foaming chamber 1 and the chamber cover 2 are prepared separately and then assembled together.

[0052] As some embodiments of the present application, the foaming chamber 1 and the chamber cover 2 are prepared by integral molding.

[0053] Further, such as Figures 1 to 10As shown, the first input port 14 and the second input port 15 are arranged at one end of the foaming device, and the bubble outlet 16 is arranged at the other end of the foaming device. The first foaming structure 11, the second foaming structure 12, and the third foaming structure 13 are arranged in sequence in the middle of the foaming device. After the external liquid and gas enter the cavity through the first input port 14 and the second input port 15 respectively, they first enter the "S"-shaped channel in the first foaming structure 11, and then enter the inlet 121 in the second foaming structure 12, and then are blocked and guided by the retaining wall 123, enter the outlet 124, and after being discharged from the outlet 124, enter the flow channel 132 in the third foaming structure 13, and finally discharge from the foaming device through the bubble outlet 16.

[0054] The foaming device described in the present application cooperates with the three-stage foaming device of the first foaming structure 11, the second foaming structure 12, and the third foaming structure 13, so that the gas and liquid are mixed evenly, the foaming effect is good, and the prepared foam is dense and uniform. Specifically, the "S"-shaped channel in the first foaming structure 11 is tortuous, which can make the liquid and gas fully mixed and initially foamed, and the second foaming structure 12 blocks and guides the foam ejected by the first foaming structure 11 through the action of the retaining wall 123, so that the liquid and gas in the foam are further mixed and foamed; the third foaming structure 13 shears the foam discharged from the second foaming structure 12 through the "Y"-shaped guide member 131, so that the foam is uniform and dense, and prevents the bubbles in the foam from being of different sizes.

[0055] Further, such as Figure 8 As shown, the first input port 14 and the second input port 15 are hollow columnar structures that pass through both sides of the foaming chamber 1. Figure 6 As shown, the guide column 22 is provided on the chamber cover 2, and the guide column 22 is a columnar structure with a hollow interior. Figure 5 and 10 As shown, when the bin cover 2 and the foaming bin 1 are assembled, the guide column 22 is sleeved on the periphery of the first input port 14 or the second input port 15, so that the liquid and gas entering the cavity from the first input port 14 or the second input port 15 can be discharged from the end of the guide column 22.

[0056] As some embodiments of this application, Figure 10As shown, the guide column 22 is sleeved on the periphery of the second input port 15. After the external liquid is input into the cavity through the first input port 14, the liquid flows out from the end of the first input port 14; the external gas is input into the cavity through the second input port 15. Due to the guiding effect of the guide column 22, after the gas flows out from the end of the second input port 15, it will flow along the gap between the guide column 22 and the second input port 15, and finally flow out from the end of the guide column 22. In this way, the purpose of adjusting the outflow position and direction of the gas and liquid can be achieved, and the mutual influence between the gas and liquid flowing out from the first input port 14 and the second input port 15 can be avoided.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
