Description

Technical Field

[0001] This utility model relates to the field of bathtubs, specifically to a bathtub body that is easy to cover with film and a disposable covered bathtub formed after covering with film. Background Technology

[0002] With the popularization of the "big health" concept, the public's demand for hygiene and safety continues to upgrade. Especially in public and special service venues such as hotels, hot spring resorts, beauty salons, and postpartum care centers, the hygiene of bathroom facilities has become one of the core considerations for consumers. According to the "China Bathroom Industry Development Report," in 2023, cross-contamination complaints in domestic public bathrooms accounted for 18%, with complaints about traditional fixed bathtubs due to incomplete cleaning accounting for over 60%. Currently, in the bathroom products sector, disposable bathroom products, theoretically eliminating cross-contamination, maintain an annual market demand growth rate of over 25%. However, existing products still have technical shortcomings and struggle to meet the needs of diverse scenarios. Disposable bathtub liners (also known as disposable bathtub covers) are disposable bathroom products designed for traditional bathtubs. However, existing disposable bathtub liners, lacking anti-slip and precise positioning designs, are prone to shifting and leaking after installation, posing not only hygiene risks but also a poor user experience. Specifically, the use of disposable bathtub membranes presents the following problems: (1) the plastic membrane cannot be fixed, and the membrane is prone to shifting with the water flow during use, resulting in a poor user experience; (2) the membrane does not fit well after installation, which easily leads to water leakage and protection failure. Traditional bathtubs do not have a structure specifically designed for membrane covering needs, which makes it impossible to solve the above problems. Utility Model Content

[0003] This utility model provides a bathtub body that is easy to cover with film and a disposable covered bathtub made by covering it with film, aiming to solve the problems of "cumbersome cleaning and cross-infection" of traditional bathtubs, as well as the problems of existing disposable bathtub covers that cannot be fixed and are prone to leakage.

[0004] Regarding the bathtub body, the technical solution of this application is as follows:

[0005] A bathtub body designed for easy membrane application includes a water outlet at the bottom for installing a drain device; an air intake assembly comprising an air intake port and an external interface, the air intake port being located on the inner wall of the bathtub body and the external interface on the outer wall of the bathtub body; the external interface for connecting an air intake pump; two hooks symmetrically positioned on the outer edge of the bathtub body's opening for securing the membrane; and a rubber strip around the outer edge of the bathtub body's opening for adhering the membrane.

[0006] Compared with the prior art, this utility model facilitates the initial fixation of the membrane by setting a hook on the outer edge of the bathtub body; it facilitates the adhesion of the membrane by setting a strip around the outer edge of the bathtub body, and further fixes and seals the membrane; and it facilitates the use of an air suction pipe assembly on the bathtub body to use an air suction pump to suck out the air between the membrane and the bathtub body, so that the membrane can be adsorbed onto the bathtub body for fixation. This solves the problems of easy movement of the membrane after application and easy leakage due to the membrane not adhering properly in the prior art, and effectively improves the use effect.

[0007] Preferably, in the aforementioned bathtub body with convenient film application, the hook is located below the adhesive strip. This structure facilitates the film's adhesion and sealing to the adhesive strip around the circumference of the bathtub body. If the hook is located above the adhesive strip, the film's seal may fail.

[0008] Preferably, in the aforementioned bathtub body with convenient film application, the hook is fixed to the bathtub body by adhesive bonding. This design makes hook installation convenient, time-saving, labor-saving, and cost-effective.

[0009] Preferably, in the aforementioned bathtub body designed for easy film application, the bathtub body includes an inner tub and an outer tub that are fixedly connected, with the outer tub supporting the inner tub. This combined inner and outer tub structure facilitates the manufacture of the bathtub body and is currently the mainstream structure for bathtub products, characterized by high reliability and ease of implementation.

[0010] Preferably, in the aforementioned bathtub body with convenient film application, the air intake is located on the side wall of the inner tub, and the external interface is located on the side wall of the outer tub; the air intake is connected to the external interface through a vent pipe. Positioning the air intake on the side wall of the inner tub facilitates air intake by the air pump, allowing the film to adhere to the bathtub body; positioning the external interface on the side wall of the outer tub facilitates connection to the air pump.

[0011] Preferably, in the aforementioned bathtub body with convenient film covering, the vent pipe is located in the space between the inner tub and the outer tub. This structure makes full use of the space between the inner tub and the outer tub, and the vent pipe is hidden between the inner tub and the outer tub, thus avoiding inconvenience to the user.

[0012] Preferably, in the aforementioned bathtub body with convenient film application, the external interface is a female C-type self-locking quick connector. Using a self-locking quick connector improves ease of use and increases film application efficiency.

[0013] For disposable membrane bathtubs, the technical solution of this application is as follows:

[0014] A disposable membrane bathtub includes the aforementioned bathtub body with convenient membrane application; a drain device is installed at the water outlet; a membrane is vacuum-adhered to the inner surface of the bathtub body; the membrane has a pair of hanging holes, which cooperate with hooks; the edges of the membrane are fixed and sealed by adhesive strips. By applying a membrane to the bathtub body to form a membrane bathtub, effective and reliable hygiene protection can be provided to the user. The special structure ensures that the membrane will not move during use and is not prone to leakage, resulting in good performance.

[0015] Compared with the prior art, the disposable film bathtub of this utility model is obtained by film covering the bathtub body of the aforementioned convenient film covering of this utility model. The film is positioned by hooks and forms a seal with the bathtub body by adhesive strips. It is attached to the tub wall by vacuum adsorption. It is not easy to shift during use and will not leak, thus providing better hygiene protection performance.

[0016] Preferably, in the aforementioned disposable membrane bathtub, the membrane is a polylactic acid (PLA) film. PLA film is a biodegradable material with good environmental degradability and strong environmental properties, and it also has high physical strength, making it less prone to damage during use.

[0017] Preferably, in the aforementioned disposable membrane bathtub, an anti-slip mat is provided at the bottom of the bathtub body; the anti-slip mat is located between the membrane and the bathtub body. The anti-slip mat improves bathing safety, and since it is positioned between the membrane and the bathtub body, it does not come into contact with the human body, thus allowing for reuse and low operating costs (if the anti-slip mat is placed directly on the membrane, it cannot be reused, otherwise there is a risk of infection).
