Description

Technical Field

[0001] This utility model relates to a head sealing ring for a shampoo machine, and pertains to the field of shampoo accessory technology. Background Technology

[0002] Hair care is a common and essential task for people today. Currently, most automatic hair washing machines on the market require the head to be placed in the washing chamber of the machine, where a support column and a shampoo strap are fixedly installed to support the head. The shampoo strap's terminals rotate on the scalp to simulate the rubbing motion of fingers. For example, a belt-type hair washing machine with patent publication number CN111838932B includes a hollow shell with a washing chamber on one side to accommodate the human head. It also includes a shampooing unit, a support unit, and a water spraying unit. The user's head is placed in the washing chamber, supported by the support unit, and the top of the user's head is positioned on the shampoo strap for shampooing. However, the opening of the washing chamber in existing hair washing machines does not have an effective structure to hold the head in place, and the liquid is prone to splashing out during use, failing to achieve an effective and comfortable fit. Therefore, our company proposes an improved head sealing ring for hair washing machines. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a head sealing ring for a shampoo machine to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a head sealing ring for a shampoo machine, including a sleeve, the inner side of which is provided with an expansion bladder, the expansion bladder being used to fill with high-pressure fluid and expand elastically to the center to press against the head.

[0005] A further improvement is that an inner air groove is provided on the inner side of the collar, and the expansion bladder is located inside the inner air groove.

[0006] A further improvement is that a connecting pipe is installed on one side of the expansion bladder, which passes through one side of the inner air groove and is connected to an external air pump or water pump.

[0007] A further improvement is that the wall thickness on the opposite side of the inflatable bladder is less than the wall thickness on the outer side.

[0008] A further improvement is that the ring includes an upper U-shaped ring and a lower U-shaped ring that are relatively separated, and divides the corresponding expansion bladder into two parts, wherein the top of the upper U-shaped ring is movably hinged to the top cover of the shampoo chamber housing.

[0009] Compared with the prior art, the present invention has the following advantages: By incorporating an expansion bladder into the shampoo sleeve, which can be filled with fluids such as gas or liquid, the expansion bladder can expand and elastically press against the head. This improves the comfort of contact with the head and prevents liquid from splashing outward from the inside of the shampoo compartment, achieving a relatively sealed effect. Secondly, the ring can be divided into two corresponding parts, with the bottom of the lower U-shaped ring installed on the shampoo machine and the top of the upper U-shaped ring hinged to the top cover of the shampoo chamber. This design allows the upper U-shaped ring to be flipped up flexibly. When the upper U-shaped ring is flipped up, it is easier for the user's head to come out and go in, and the contact position with the expansion bladder can be better adjusted, which can improve the flexibility of use.

[0010] Other features, objects, and advantages of this invention will become more apparent from the following detailed description of non-limiting embodiments with reference to the accompanying drawings: Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 for Figure 1 A structural diagram from another perspective; Figure 3 This is a schematic diagram of the ring separation structure of this utility model; In the diagram: 1. Loop ring; 2. Inner air groove; 3. Expansion bladder; 4. Connecting tube; 5. Upper U-shaped ring; 6. Lower U-shaped ring. Detailed Implementation

[0011] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0012] Please see Figures 1-3 This utility model provides a technical solution for a sealing ring for a shampoo machine head: it includes a collar 1, and an expansion bladder 3 is provided on the inner side of the collar 1. The expansion bladder 3 is used for filling with external high-pressure fluid and expanding elastically to press against the head. The expansion bladder 3 can be made of rubber material, so that when gas or liquid is filled into the expansion bladder 3 by an external air pump or water pump, the opposite side of the expansion bladder 3 can expand, allowing it to fit the head tightly and improve the comfort of use and the sealing effect of the shampoo chamber to prevent liquid from splashing out. Alternatively, the expansion bladder 3 can also be replaced by a material that can be inflated by air or water in the prior art, such as PVC (polyvinyl chloride) or TPU (thermoplastic polyurethane).

[0013] Furthermore, an inner air groove 2 is provided on the inner side of the collar 1. The inner air groove 2 is designed to open towards the center, and the expansion bladder 3 is compounded on the inner side of the inner air groove 2. Therefore, when the expansion bladder 3 expands, it can be guided to expand towards the center along the inner air groove 2, making the expansion direction more concentrated. At the same time, the wall thickness on the opposite side of the expansion bladder 3 is less than the wall thickness on the outer side. This also allows the opposite side with the smaller wall thickness of the expansion bladder 3 to expand first during expansion, so as to better guide the expansion to the desired direction.

[0014] The expansion bladder 3 has a connecting pipe 4 installed on one side. The connecting pipe passes through one side of the inner air groove 2 and is connected to a high-pressure fluid air pump or water pump to fill or release the gas or liquid inside the expansion bladder 3.

[0015] In addition, such as Figure 3 As shown, the collar 1 can be divided into two parts, upper and lower. The bottom of the lower U-shaped collar 6 is installed on the shampoo machine, while the top of the upper U-shaped collar 5 is movably hinged to the top cover of the shampoo chamber. After the collar 1 is separated, the rear expansion bladder 3 inside the lower U-shaped collar 6 and the upper U-shaped collar 5 are also divided into separate parts. Two connecting pipes 4 are set to pass through the inner air groove 2 to connect with the lower U-shaped collar 6 and the upper U-shaped collar 5 respectively. This design allows the upper U-shaped collar 5 to be flexibly flipped. After the upper U-shaped collar 5 is flipped upward, it is easier for the user's head to enter. The flipping of the upper U-shaped collar 5 can also better adjust the contact position between the expansion bladder 3 and the head, which can improve the flexibility of use.

[0016] It should be noted that the present invention provides a head sealing ring for a shampoo machine, which mainly improves the above-mentioned structure. The functions, components and structures not mentioned can be implemented by using existing components and structures that can achieve the corresponding functions.

[0017] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
