[0002] A steam cleaner is a device that heats water to generate steam and uses the steam for cleaning.

[0003] Currently, steam cleaners generate high pressure when heating steam. If the pressure is not properly controlled, there may be safety hazards.

[0004] Therefore, there is an urgent need to design a steam cleaner with pressure relief protection function. Utility Model Content

[0005] (I) Purpose of the utility model

[0006] In view of this, the purpose of this utility model is to propose a steam cleaner with pressure relief protection function, which can provide pressure relief protection and improve the safety of overpressure gas discharge.

[0007] (II) Technical Solution

[0008] To achieve the above technical objectives, this utility model provides a steam cleaner with pressure relief protection function:

[0009] It includes a main housing, inside which a water storage tank is fixed, which is used to supply water to the main housing. A booster pump and a heat pump are fixed inside the main housing. The inner cavity of the water storage tank is connected to the heat pump through the booster pump. The heat pump is connected to a pressure relief valve, which is connected to a cooling tank through a conduit.

[0010] Preferably, the outer surface of the main housing is fixed with a handle, and the outer surface of the handle is provided with a switch.

[0011] Preferably, the outer surface of the main housing is connected to a spray gun via a tube bundle, and the inner cavity of the spray gun is connected to a heat pump via the tube bundle.

[0012] Preferably, the water storage tank has a spout fixed to its outer surface, the spout penetrating the surface of the main shell, and a cap is threaded onto the spout.

[0013] Preferably, the pressure relief valve includes a valve body, which is fixedly and sealed to the heat pump by a sealing ring. The valve body is open from top to bottom, and a valve core is fixed inside the valve body. A plug is slidably connected inside the valve core, and a plug is threadedly connected inside the valve core. A spring is provided between the plug and the plug.

[0014] Preferably, the valve body has a pressure relief hole on its outer surface, the valve core has a through hole on its outer surface, the valve core's inner cavity is connected to the pressure relief hole through the through hole, and the pressure relief hole is connected to the inner cavity of the cooling box through a conduit.

[0027] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0028] Reference Figure 1-5 A steam cleaner with pressure relief protection function includes a main housing 1, a water tank 2 fixed inside the main housing 1 for supplying water to the main housing 1, a booster pump 3 and a heat pump 4 fixed inside the main housing 1, the inner cavity of the water tank 2 being connected to the heat pump 4 through the booster pump 3, the heat pump 4 being connected to a pressure relief valve 5, the pressure relief valve 5 being connected to a cooling tank 6 through a conduit, a spray gun 12 being connected to the outer surface of the main housing 1 through a tube bundle 11, and the inner cavity of the spray gun 12 being connected to the heat pump 4 through the tube bundle 11; a handle 14 being fixed to the outer surface of the main housing 1, and rollers 15 being rotatably connected to the bottom of the main housing 1 for easy movement of the main housing 1;

[0029] Specifically, the control method of switch 121 in this embodiment is as follows: switch 121 is used to control solenoid valve, and the solenoid valve controls the heat pump 4 to communicate with the inside of spray gun 12 to realize the control of steam injection; or switch 121 is directly connected to press-type mechanical valve, and the press-type mechanical valve controls the heat pump 4 to communicate with the inside of spray gun 12. If it is a solenoid valve, the tube bundle 11 is composed of wires and conduits, while the press-type mechanical valve is only composed of conduits; a power switch is fixed on the main housing 1, and the power switch is electrically connected to booster pump 3 and heat pump 4;

[0030] For example, by turning on the power switch, the booster pump 3 is activated, drawing water from the water tank 2 into the heat pump 4 to generate steam. The steam can then be controlled to be sent into the spray gun 12 and sprayed out by pressing the switch 121.

[0031] It is worth mentioning that in this embodiment, the power supply for the booster pump 3 and the heat pump 4 can be directly connected to the mains power, or a battery can be installed in the main housing 1. The heat pump 4 is a resistance wire heating or other structure with heating function. The heat pump 4 integrates a temperature sensor and a controller. After heating to a certain threshold, the booster pump 3 and the heat pump 4 will stop working. The specific control method and related structure are not specifically limited here.

[0032] Furthermore, a spout is fixed to the exterior of the water storage tank 2, the spout penetrates the surface of the main shell 1, and a cap 13 is threaded onto the spout. Water can be added to the water storage tank 2 by opening the cap 13.

[0033] Specifically, the pressure relief valve 5 includes a valve body 51, which is fixedly and sealed to the heat pump 4 via a sealing ring 512. The valve body 51 is open from top to bottom, and a valve core 52 is fixed inside the valve body 51. A plug 522 is slidably connected inside the valve core 52, and a plug 521 is threaded inside the valve core 52. A spring 523 is provided between the plug 521 and the plug 522. A pressure relief hole 511 is provided on the outer surface of the valve body 51, and a through hole 524 is provided on the outer surface of the valve core 52. The inner cavity of the valve core 52 communicates with the pressure relief hole 511 through the through hole 524. The pressure relief hole 511 communicates with the inner cavity of the cooling box 6 through a conduit. For example, when the pressure inside the heat pump 4 is too high, it will push the plug 522, causing the spring 523 to contract, thereby exposing the through hole 524. Figure 5 As shown, the overpressure gas in the heat pump 4 enters the valve core 52 from the valve body 51, and then enters the cooling box 6 for cooling and pressure reduction through the through hole 524 and the pressure relief hole 511 in sequence.

[0034] More specifically, the interior of the cooling box 6 is uniformly fixed with partitions 61, which divide the interior of the cooling box 6 into multiple flow channels, increasing the heat exchange time between the overpressure gas and the cooling box 6. The outer surface of the cooling box 6 is fixed with an exhaust pipe 62 and an intake pipe 63, and the pressure relief hole 511 is connected to the intake pipe 63 through a conduit. For example, in this embodiment, the cooling box 6 is a sealed metal tank, which is attached to the outer surface of the water storage tank 2 to facilitate heat exchange between the water storage tank 2 and the cooling box 6. The partitions 61 are made of metal with good thermal conductivity, such as aluminum alloy or copper alloy, without specific limitation. Overpressured steam enters the cooling box 6 and passes through multiple staggered partitions 61 in sequence, which can cool and reduce the pressure before being discharged through the exhaust pipe 62, thus solving the overpressure problem.

[0035] Furthermore, in order to improve the heat exchange effect, the partition 61 is designed as a hollow structure, and the inner cavity is connected to the water storage tank 2, which further increases the heat exchange effect.

[0036] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
