Description

Technical Field

[0001] This utility model relates to the field of steam cleaners, and in particular to a nozzle anti-clogging structure for steam cleaners. Background Technology

[0002] Steam cleaners utilize the high temperature and pressure of saturated steam to remove grease and dirt from surfaces, vaporizing it. They are particularly suitable for cleaning kitchen range hoods, stoves, and other similar items. Handheld steam cleaners are popular among consumers due to their ease of use and flexibility.

[0003] Existing steam cleaners are often equipped with a nozzle structure at the front end of the main body. The steam generated inside the cleaner is sprayed out to the outside through the nozzle structure to achieve the effect of steam cleaning. However, during daily use, the steam outlet on the nozzle structure may be blocked by other objects, preventing the internal steam from being sprayed out. This not only prevents the user from using the machine normally, but also causes excessive pressure inside the steam cleaner due to the inability to release pressure, which can damage the internal parts of the cleaner. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a nozzle anti-clogging structure for steam cleaners, based on the current state of the technology.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a nozzle anti-clogging structure for a steam cleaner, including a cleaner body and a nozzle structure located at the front end of the cleaner body. The end of the nozzle structure away from the cleaner body is a steam outlet end. A steam injection hole communicating with the inside of the nozzle structure is opened on the steam outlet end. A pressure relief anti-clogging structure is also provided on the steam outlet end to prevent steam from being unable to be ejected when the steam injection hole is blocked. The pressure relief anti-clogging structure is arranged near the steam injection hole.

[0006] Preferably, the steam outlet end includes a nozzle end face, and the steam injection hole and the pressure relief and anti-clogging structure are both formed on the nozzle end face. The pressure relief and anti-clogging structure includes at least one pressure relief groove provided on the nozzle end face.

[0007] Preferably, the pressure relief groove is recessed on the nozzle end face, one end of the pressure relief groove is connected to the steam injection hole, and the other end of the pressure relief groove extends away from the steam injection hole and is connected to the edge of the nozzle end face.

[0008] Preferably, the nozzle structure has a steam channel inside that connects the inside of the cleaning machine body and the steam injection hole. The steam generated inside the cleaning machine body is discharged from the steam injection hole through the steam channel. When the steam injection hole is blocked, the steam in the steam channel is discharged to the outside through the pressure relief groove connected to the steam injection hole.

[0009] Preferably, the pressure relief and anti-blocking structure includes a pressure relief rib arranged around the outer edge of the nozzle end face, the pressure relief rib protruding from the nozzle end face, the steam injection hole arranged in the inner perimeter of the pressure relief rib near the center, and at least one pressure relief notch for pressure relief is opened at any position on the pressure relief rib.

[0010] Preferably, when the steam injection hole is blocked, the steam in the steam passage is ejected to the outside through the pressure relief notch on the side of the steam injection hole to relieve pressure.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by opening a pressure relief and anti-blocking structure on the nozzle end face with a steam injection hole, even if the steam injection hole is blocked by an external object during use, the steam in the steam channel can be discharged to the outside through the pressure relief and anti-blocking structure. This not only ensures the normal use of the product in daily life, but also prevents problems such as excessive internal pressure and damage to internal structural parts caused by the inability of internal steam to be discharged.

Example 1

[0019] like Figures 1 to 4 As shown, this utility model provides a nozzle anti-clogging structure for a steam cleaner, including a cleaner body 1 and a nozzle structure 2 located at the front end of the cleaner body 1; specifically, the end of the nozzle structure 2 away from the cleaner body 1 is a steam outlet end 3, and a steam injection hole 4 communicating with the inside of the nozzle structure 2 is provided on the steam outlet end 3. The steam outlet end 3 is also provided with a pressure relief anti-clogging structure to prevent steam from being unable to be ejected when the steam injection hole 4 is blocked. The pressure relief anti-clogging structure is arranged near the steam injection hole 4.

[0020] The internal structural components of the main body 1 of the cleaning machine and the working principle of the steam generated are common and easily conceived by those skilled in the art, so they will not be described in detail.

[0021] The steam outlet end 3 includes a nozzle end face 5, a steam injection hole 4, and a pressure relief and anti-blocking structure, all of which are provided on the nozzle end face 5; specifically, the pressure relief and anti-blocking structure includes at least one pressure relief groove 6 provided on the nozzle end face 5.

[0022] The pressure relief groove 6 is recessed on the nozzle end face 5; specifically, one end of the pressure relief groove 6 is connected to the steam injection hole 4, and the other end of the pressure relief groove 6 extends away from the steam injection hole 4 and is connected to the edge of the nozzle end face 5.

[0023] The nozzle structure 2 has a steam channel 7 inside that connects the inside of the cleaning machine body 1 and the steam injection hole 4. The steam generated inside the cleaning machine body 1 is discharged from the steam injection hole 4 through the steam channel 7. Specifically, when the steam injection hole 4 is blocked, the steam in the steam channel 7 is discharged to the outside through the pressure relief groove 6 that is connected to the steam injection hole 4.

[0024] The working principle of this utility model is as follows: Steam is generated inside the main body 1 of the cleaning machine. The steam is discharged through the steam channel 7 inside the nozzle structure 2. The steam is then sprayed out to the outside through the steam injection hole 4 connected to the steam channel 7 for steam cleaning. When the steam injection hole 4 is blocked by an external object, at least one pressure relief groove 6 is provided on the nozzle end face 5. The two ends of the pressure relief groove 6 are respectively connected to the steam injection hole 4 and the edge of the nozzle end face 5. The pressure relief groove 6 is recessed on the nozzle end face 5. The steam in the steam channel 7 can be sprayed out through the gap between the steam injection hole 4 and the pressure relief groove 6, and then sprayed out to the outside along the pressure relief groove 6. This plays the role of normal machine operation and pressure relief inside the main body 1 of the cleaning machine.

[0025] The advantages of this utility model are as follows: by opening a pressure relief and anti-blocking structure on the nozzle end face 5 with steam injection hole 4, even if the steam injection hole 4 is blocked by external objects during use, the steam in the steam channel 7 can be discharged to the outside through the pressure relief and anti-blocking structure. This not only ensures the normal use of the product in daily life, but also prevents problems such as excessive internal pressure and damage to internal structural parts caused by the inability of internal steam to be discharged.

[0027] When the steam injection hole 4 is blocked, the steam in the steam passage 7 is ejected to the outside through the pressure relief notch 9 on the side of the steam injection hole 4 to relieve pressure.

[0028] The other structures are the same as in Example 1.
