Description

TECHNICAL FIELD

[0001] The utility model relates to a steam cleaner technical field especially relates to a steam cleaner of air release valve rear -positioning. BACKGROUND

[0002] In modern family and commercial environment, cleaning work is an important link to maintain health and health. The traditional cleaning method often relies on manual operation and chemical cleaning agent, which is not only inefficient, but also can cause negative impact on the environment and human health. With the progress of science and technology, steam cleaner as an efficient, environmentally friendly cleaning tool, gradually receives people's favor. Steam cleaner removes stains and sterilizes through high-temperature steam, without using chemical cleaning agent, which is environmentally friendly and safe. However, the existing steam cleaner has some problems in the use process. First, the air release valve of the existing steam generator is usually located at the front end or side of the equipment. When using forwardly, the water in the steam generator is easy to overflow the air release valve, which causes the steam cleaner to spray hot water and causes safety problems. Secondly, the sealing and safety of the steam cleaner are also the focus of users. If the design of the air release valve is unreasonable or the sealing is poor, it may cause steam leakage, affect the cleaning effect and even cause safety hazards. In addition, the existing steam cleaner is often complex in structure, which not only increases the manufacturing cost, but also brings difficulties to the use and maintenance of users. Therefore, it is necessary to provide a steam cleaner with a rear-mounted air release valve with good sealing. SUMMARY

[0003] The utility model aims at solving at least one of the above technical problems.

[0004] In order to solve the above problems, the first purpose of the utility model is to provide a steam cleaner with a rear-mounted air release valve, which comprises: a shell, the shell is provided with an air outlet pipe; a steam generator, the steam generator is placed in the shell, and the side of the steam generator away from the air outlet pipe is provided with an air release valve, and the air release valve is communicated with the air outlet pipe.

[0005] When the steam cleaner is used forwardly, if the air release valve is front-mounted, the water in the steam generator may overflow the air release valve, which causes the hot water to flow out of the air release valve and then be sprayed out of the air outlet pipe, causing safety problems. Rear mounting of the air release valve can avoid this situation and ensure that the air release valve can work normally all the time. The setting of the air release valve can ensure that the steam in the steam generator can be discharged in time during the steam cleaning process, so as to maintain the stability of the air pressure in the steam generator and avoid excessive wear and tear or damage of the internal components of the equipment due to excessive air pressure.

[0006] In the technical solution, the steam generator is provided with a first inner cavity, and the air release valve comprises: an air inlet, which is in communication with the first inner cavity; an air outlet, which is in communication with the air outlet pipe; and a sealing block, which is located between the air outlet and the air inlet.

[0007] By connecting the air inlet with the first inner cavity of the steam generator, it can be ensured that the excess gas generated in the first inner cavity can smoothly enter the air release valve. The air outlet is in communication with the air outlet pipe, which ensures that the steam discharged from the air release valve can be smoothly discharged from the shell, and then cleaning work can be performed through the steam. The sealing block is located between the air outlet and the air inlet: the presence of the sealing block can ensure that the channel between the air inlet and the air outlet is effectively sealed when air release is not required, preventing steam from leaking from the channel and ensuring the safety of the steam cleaner. The presence of the sealing block can effectively prevent steam from leaking from the channel between the air inlet and the air outlet. This can ensure that steam does not leak out, reducing energy waste and improving the energy efficiency of the equipment. By adjusting the sealing block, the opening degree of the air release valve can be controlled, and then the steam discharge amount can be controlled, which can be adjusted according to the cleaning requirements, improving the practicality of the steam cleaner.

[0008] In any of the above technical solutions, the shell is provided with an air release switch, and the air release switch abuts against the sealing block.

[0009] The air release switch can accurately control the position of the sealing block. When the air release switch is activated, it will push or release the sealing block, thereby opening or closing the air outlet. By accurately controlling the position of the sealing block, the air release switch can accurately control the steam discharge amount. The design of the air release switch allows users to control the air release process by simply operating the switch, improving the operation convenience of the equipment. By accurately controlling the air pressure, unnecessary energy waste caused by excessive air pressure can be avoided. The air release switch can ensure that steam is released in time when needed, thereby improving the energy efficiency of the equipment.

[0010] In any of the above technical solutions, the shell is provided with an elastic sheet, and the elastic sheet abuts against the air release switch.

[0011] The provision of the elastic sheet can provide a certain buffering effect for the air release switch, avoiding component wear caused by vibration of the steam cleaner during use, and improving the overall safety and reliability of the steam cleaner. The design of the air release switch and the elastic sheet makes it easier to maintain and replace the equipment when it fails, reducing the complexity and cost of maintenance. After the user presses and releases the air release switch, the elastic sheet can reset the air release switch through the elastic restoring force, improving the convenience of the steam cleaner.

[0012] In any of the above technical solutions, the shell is provided with a locking member, and the locking member has a locked state and an unlocked state. In the locked state, the locking member abuts against the air release switch; in the unlocked state, the locking member is away from the air release switch.

[0013] In the locked state, the locking member abuts against the deflation switch, preventing the user from accidentally triggering the deflation switch and reducing the risk of misoperation. The locking member ensures that the deflation switch cannot be accidentally opened during non-working state or maintenance, protecting the internal structure from damage. The presence of the locking member makes the operation of the device more in line with safety operation procedures, ensuring safe and reliable operation of the device in different states. The presence of the locking member can effectively prevent the deflation switch from being frequently operated unnecessarily, thereby reducing wear and tear of the deflation switch and related components, prolonging the service life of the device. The locking member can ensure that the deflation switch does not accidentally open when the device is not in use, thereby reducing unnecessary gas loss and improving the energy efficiency of the device.

[0014] In any of the above technical solutions, the steam cleaner with the rear-mounted deflation valve further comprises a liquid injection port, which is in communication with the first inner cavity.

[0015] The design of the liquid injection port allows users to conveniently inject steam generator liquid or cleaning liquid and other liquids into the first inner cavity of the steam generator without disassembling other components, simplifying the refilling process. The design of the liquid injection port in communication with the first inner cavity makes the overall structure more compact and integrated, reducing additional pipelines and interfaces and simplifying the overall structure. Through reasonable sealing design, the connection between the liquid injection port and the first inner cavity can ensure that there is no liquid leakage, ensuring the sealing and reliability of the device.

[0016] In any of the above technical solutions, the steam cleaner with the rear-mounted deflation valve further comprises a sealing cover, which cooperates with the liquid injection port.

[0017] The sealing cover cooperates with the liquid injection port to effectively prevent liquid from leaking from the liquid injection port, ensuring that the internal liquid does not overflow and maintaining the sealing and cleanliness of the device. The sealing cover can seal the liquid injection port, preventing external contaminants from entering the device interior and maintaining the cleanliness and hygiene of the device interior. When refilling cleaning agent or other liquids is required, the sealing cover can be easily opened, refilled and resealed after refilling, which is convenient and fast. The use of the sealing cover can reduce the leakage of internal liquid, thereby reducing the wear and tear of internal components caused by leakage. The sealing cover can protect the internal precision components from the external environment, prolonging the service life of the device.

[0018] In any of the above technical solutions, a second inner cavity is provided between the housing and the steam generator.

[0019] The second inner cavity can serve as a thermal isolation layer, reducing the direct transfer of heat generated by the steam generator to the shell, thereby reducing the temperature of the shell, reducing the thermal stress of the shell material, and prolonging the service life of the equipment. The second inner cavity can be designed to optimize the thermal efficiency of the steam generator, reduce energy loss, and improve the overall energy efficiency of the equipment. The second inner cavity can provide additional structural support, enhancing the stability and robustness of the entire steam cleaner, reducing deformation or damage caused by mechanical stress. The second inner cavity can serve as a buffer zone, reducing stress concentration caused by direct contact between the steam generator and the shell, improving the durability of the overall structure. The presence of the second inner cavity makes it easier to disassemble and maintain the components between the steam generator and the shell, facilitating internal cleaning and maintenance for the user.

[0020] In any of the above technical solutions, the steam generator is provided with a support, and the support abuts against the shell.

[0021] The support can provide additional support for the steam generator, ensuring that it is securely installed within the shell and reducing displacement or tilting caused by vibration or pressure. The contact between the support and the shell can effectively absorb and disperse vibrations, reducing the amplitude of vibrations during equipment operation and improving overall stability. The contact between the support and the shell can reduce noise generated during equipment operation, improving operational silence. The presence of the support can ensure that the equipment remains stable during long-term operation, reducing operational interruptions or failures caused by unstable structures. The contact between the support and the shell can assist in regulating the pressure inside the steam generator, ensuring stable and efficient operation of the equipment.

[0022] In any of the above technical solutions, the steam generator is provided with a heating device, and the heating device is arranged on the side of the support away from the shell.

[0023] Arranging the heating device on the side of the support away from the shell can effectively isolate direct heat transfer to the shell, reducing the risk of overheating the shell. The presence of the support can provide additional space, allowing the heating device to maintain an appropriate distance from the shell, thereby optimizing the overall structural design of the equipment. By isolating the heating device and the shell, safety hazards caused by overheating of the shell can be effectively prevented, improving the safety of the equipment. By isolating and optimizing the design, it can be ensured that the equipment remains stable during long-term operation, reducing operational interruptions or failures caused by local overheating.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict. In the following description, a large number of specific details are set forth in order to facilitate a full understanding of the present application, but the present application can also be implemented in other ways different from those described herein, and therefore the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0031] As shown in Figure 1 , Figure 2 and Figure 4 , the specific embodiments of the present application provide a steam cleaner with a rear-mounted air release valve, which comprises: a housing 100, the housing 100 being provided with an air outlet pipe 110; a steam generator 200, the steam generator 200 being arranged in the housing 100, the steam generator 200 being provided with a first inner cavity 220, and the steam generator 200 being provided with an air release valve 210 on a side away from the air outlet pipe 110, the air release valve 210 being in communication with the air outlet pipe 110, the air release valve 210 comprising: an air inlet 211, the air inlet 211 being in communication with the first inner cavity 220; an air release port 212, the air release port 212 being in communication with the air outlet pipe 110; and a sealing block 213, the sealing block 213 being located between the air release port 212 and the air inlet 211.

[0032] ​In this embodiment, the steam generator 200 is a bottle-shaped structure with an inner cavity, the steam generator 200 is arranged in the shell 100, the air outlet pipe 110 is arranged at the front side of the shell 100 and also at the front side of the steam generator 200, and the air release valve 210 is arranged at the rear side of the steam generator 200 and also at the rear side of the shell 100. When the user uses the steam cleaner by tilting it downward, the liquid in the first inner cavity 220 also moves downward, at this time, the air outlet pipe 110 is below, and the liquid in the first inner cavity 220 is also below, but by placing the air release valve 210 at the rear side, the air release valve 210 is above at this time, which avoids the liquid in the first inner cavity 220 from overflowing the air release valve 210, causing hot water to finally be sprayed out of the air outlet pipe 110 and causing a safety problem. The air release valve 210 specifically includes an air inlet 211, an air outlet 212, a sealing block 213, and a valve body, the valve body has a left cavity and a right cavity, the diameter of the left cavity is smaller than the diameter of the right cavity, the air inlet 211 is located at the right cavity, and the air outlet 212 is located at the left cavity. The left side of the sealing block 213 protrudes out of the valve body, the right side of the sealing block 213 has a sealing ring and is slightly larger in diameter than the left cavity of the valve body, so as to ensure that the sealing block 213 can completely seal the left cavity of the valve body, and the diameter of the right side of the sealing block 213 is smaller than the diameter of the right cavity of the valve body, so as to ensure that when the sealing block 213 moves to the right, the left cavity of the valve body and the right cavity of the valve body can communicate, so that the steam in the first inner cavity 220 can enter the air release valve 210 from the air inlet 211, and then enter the air outlet 212 in the left cavity of the valve body and be sprayed to the place to be cleaned through the air outlet pipe 110.

[0033] As shown in Figure 2 , Figure 3 and Figure 4 , the shell 100 is provided with an air release switch 120, the air release switch 120 abuts against the sealing block 213; the shell 100 is provided with an elastic sheet 121, the elastic sheet 121 abuts against the air release switch 120; and the shell 100 is provided with a locking piece 130, the locking piece 130 has a locked state and an unlocked state, in the locked state, the locking piece 130 abuts against the air release switch 120, and in the unlocked state, the locking piece 130 is away from the air release switch 120.

[0034] In the embodiment, the left side of the shell 100 is provided with a deflation switch 120, the right side of the deflation switch 120 abuts against the left end of the sealing block 213, the left side part of the deflation switch 120 can be directly pressed, the middle part of the deflation switch 120 is provided with a rotating shaft, when the left side part of the deflation switch 120 can be directly pressed by the user, due to the action of the rotating shaft, the right side part of the deflation switch 120 will move to the right, so as to push the sealing block 213 to move to the right, and then make the deflation valve 210 in an open state so that the steam cleaner can spray steam. The elastic sheet 121 installed in the inside of the deflation switch 120 deforms together with the deflation switch 120 when the deflation switch 120 is pressed, after the user releases the deflation switch 120, the elastic restoring force of the elastic sheet 121 resets the deflation switch 120, so that the right side of the deflation switch 120 moves to the left, and the steam in the first inner cavity 220 has a certain air pressure, the right side of the sealing block 213 is affected by the air pressure, so that the sealing block 213 moves to the left until the deflation valve 210 is closed, so that the deflation switch 120 can be released to close the deflation valve 210 and stop the steam cleaner. Through the above scheme, the user can control whether the steam cleaner sprays steam through the deflation switch 120. The locking piece 130 abuts against the upper end of the left side of the deflation switch 120 in the locking state, so that the deflation switch 120 cannot displace, that is, the right side of the deflation switch 120 cannot move to the right position abutting against the sealing block 213, and then the deflation valve 210 cannot be opened, so as to achieve the effect of locking the steam cleaner. When the locking piece 130 is in the unlocking state, the locking piece 130 is away from the deflation switch 120, so that the deflation switch 120 has a moving space, at this time the user can press the deflation switch 120 to control the steam to be sprayed out.

[0035] As shown in Figure 1 and Figure 4 , the steam cleaner with the rear deflation valve further comprises: a liquid injection port 300, the liquid injection port 300 communicates with the first inner cavity 220; a sealing cover 400, the sealing cover 400 cooperates with the liquid injection port 300; the shell 100 and the steam generator 200 are provided with a second inner cavity 140; the steam generator 200 is provided with a bracket 230, the bracket 230 abuts against the shell 100; the steam generator 200 is provided with a heating device 240, the heating device 240 is arranged on the side of the bracket 230 away from the shell 100.

[0036] In this embodiment, liquid is directly injected into the first inner cavity 220 through the liquid injection port 300, which can be water or cleaning liquid, etc., and after the injection is completed, the liquid injection port 300 is sealed by the sealing cover 400 to avoid liquid leakage and other phenomena during use. A tubular object is also provided at the liquid injection port 300, and the injected liquid flows into the first inner cavity 220 through the tubular object. The user injects liquid into the liquid injection port 300, and when the liquid reaches the lower end opening of the tubular object, further injection of liquid will be prevented due to the air pressure generated by the compression of the remaining space in the first inner cavity 220, which will prevent the first inner cavity 220 from being filled with liquid and causing the safety problem of spraying hot water. The sealing cover 400 is a cover body with a pressure relief valve function, and when the steam generated in the first inner cavity 220 is too much to cause excessive internal pressure, some gas will be discharged from the sealing cover 400 to avoid the safety problem of explosion of the steam generator 200 due to excessive internal pressure. The second inner cavity 140 is provided between the shell 100 and the steam generator 200 to ensure that the heat of the steam generator 200 is not directly transmitted to the shell 100, thereby improving the safety of the steam cleaning machine. The bottom of the steam generator 200 is provided with a heating device 240, which can directly heat the liquid in the first inner cavity 220 to generate steam. The heating device 240 is provided below the bracket 230, so that the heating device 240 is separated from the shell 100, thereby improving the safety of the steam cleaning machine.
