[0002] After use, kitchen and bathroom utensils and facilities (such as kitchen and bathroom appliances, cooking ranges, tableware, sinks, toilets, etc.) will have contaminants left on the surface. In order to ensure the normal use and hygiene of kitchen and bathroom utensils and facilities, it is necessary to clean them regularly. However, using cleaning agents to clean kitchen and bathroom utensils and facilities is relatively cumbersome, and it is easy to leave cleaning agents on the surface of kitchen and bathroom utensils and facilities. If the cleaning agents are contacted and ingested by the human body, it will affect human health. When using hot water to rinse kitchen and bathroom utensils and facilities, in order to avoid scalding the cleaner, the water temperature is generally lower than 80°, resulting in poor cleaning effect, and some kitchen appliances and facilities cannot be used normally after being washed. SUMMARY

By arranging the control module on the body, the user can easily operate the cleaning spray gun to spray fluid.

[0007] Preferably, the control module is provided with a safety switch, which is used to control the working of the water supply device and the steam supply device.

[0008] When the safety switch is in the locked state, the water supply device and the steam generation device are in the closed state; when the safety switch is in the open state, the water supply device and the steam generation device are in the startable state; by setting the safety switch, the safety of the present application can be improved, and the user can be prevented from being injured due to the user's wrong operation.

[0010] By setting the first discharge channel and the second discharge channel, the fluid output by the first fluid channel and the second fluid channel can be guided, so that the fluid output by the first fluid channel and the second fluid channel is stably sprayed from the first spray hole and the second spray hole. In addition, by setting the first discharge channel and the second discharge channel, the production personnel can adjust the specifications of the first discharge channel and the second discharge channel, so as to reduce the assembly difficulty of the first fluid channel and the second fluid channel with the spray head.

[0011] Preferably, the body comprises a cavity with an open lower end, and the upper end of the body is provided with a connecting hole in communication with the cavity; the first fluid channel is a first pipe body, and the second fluid channel is a second pipe body; the first pipe body and the second pipe body are inserted into the cavity from the lower side of the body and connected with the first discharge channel and the second discharge channel, respectively. By adopting this setting mode, the body has a simple structure and low cost, and since the first pipe body and the second pipe body are suspended relative to the inside of the cavity, heat generated after the fluid is introduced into the first pipe body and / or the second pipe body can be avoided from being transferred to the body, so as to avoid the user from being scalded when holding the body. In addition, the first fluid channel is a first pipe body, and the second fluid channel is a second pipe body, which are independently arranged relative to the body, so as to reduce the production difficulty and production cost of the cleaning spray gun and facilitate the production personnel to select appropriate materials for production according to actual needs.

[0012] Preferably, the first adapter channel connecting the first discharge channel and the first pipe body and the second adapter channel connecting the second discharge channel and the second pipe body are further included; the first adapter channel is formed by an internal channel of a first adapter, two ends of the first adapter are respectively arranged at ports connecting the first discharge channel and the first pipe body; the second adapter channel is formed by an internal channel of a second adapter, two ends of the second adapter are respectively arranged at ports connecting the second discharge channel and the second pipe body; the first adapter and the second adapter are an integral piece, or the first adapter and the second adapter are each an independent piece.

[0014] Preferably, the bracket is further included, the bracket is assembled into the chamber from the lower side, and the bracket is provided with a fixing structure corresponding to the arrangement track of the first pipe body and the second pipe body.

[0015] By arranging the bracket and arranging the fixing structure for fixing the first pipe body and the second pipe body on the bracket, the structural strength of the first pipe body and the second pipe body can be improved, and displacement of the first pipe body and the second pipe body during use of the cleaning spray gun by a user can be avoided, thereby ensuring the reliability of the cleaning spray gun, improving the smoothness of fluid sprayed by the cleaning spray gun, and improving the cleaning effect.

By connecting the first fluid channel and the second fluid channel to a first water inlet valve and a steam generating device, respectively, the cleaning spray gun can be used in conjunction with the water heating mechanism, thereby enabling the cleaning device to output two different fluids, thereby facilitating the user to use clean water or steam to clean kitchen and bathroom appliances and facilities;

[0019] (2) When users use steam to clean and disinfect items at high temperatures, steam disinfection does not require the use of detergents, thereby avoiding detergent residues on the surface of the items. Steam disinfection can also be used for some kitchen and bathroom appliances and facilities that cannot be cleaned with water, thereby avoiding the situation where kitchen and bathroom appliances and facilities cannot be used normally after cleaning. In addition, steam can fully soften oil stains. Under the impact of the steam airflow, the oil stains can be quickly blown away and removed, thereby shortening the time spent by users on cleaning;

[0020] (3) The water input of the water heating mechanism is connected to the water supply pipeline through a relatively independent water inlet valve, thereby ensuring that the components outputting different fluids can operate relatively independently, thereby improving work efficiency.

[0021] Preferably, a heating device is connected between the first water inlet valve and the cleaning spray gun, the water inlet end of the heating device is communicated with the first water inlet valve, and the water outlet end of the heating device is communicated with the first fluid channel.

[0022] By setting up a heating device, the water flowing from the first water inlet valve to the cleaning spray gun can be heated, so that the water heating mechanism can output normal temperature water (when the heating device is not working) or hot water to the cleaning spray gun, so that users can choose normal temperature water, hot water and steam for cleaning according to actual cleaning needs, thereby increasing the applicable scenarios of the cleaning device, and the cleaning effect of hot water is better than that of normal temperature water, thereby improving the cleaning effect of the cleaning device.

DETAILED DESCRIPTION

[0037] The following describes the embodiments of the present invention with reference to the accompanying drawings:

[0038] Example 1

[0039] See also Figure 1 、 Figure 2 and Figure 7The cleaning spray gun 1 of this embodiment includes a body 2, and a spray head 11 and a bracket 54 are provided at the upper end of the body 2.

[0040] A first spray hole 121 and a second spray hole 122 are provided on the nozzle 11, and a first fluid channel 401 and a second fluid channel 402 are provided in the main body 2. One end of the first fluid channel 401 and the second fluid channel 402 are respectively connected to the first spray hole 121 and the second spray hole 122, and the other end of the first fluid channel 401 and the second fluid channel 402 are respectively used to receive water or steam input.

[0041] See also Figure 7 In order to reduce the lateral volume of the nozzle head 11 and improve the aesthetics of the nozzle head 11, the first nozzle hole 121 and the second nozzle hole 122 on the nozzle head 11 are arranged vertically up and down; the first nozzle hole 121 (or the second nozzle hole 122) of the first fluid channel 401 (or the second fluid channel 402) that outputs steam is provided with a nozzle 14 (in this embodiment, the second fluid channel 402 and the second nozzle hole 122 output steam, so the nozzle 14 is provided on the second nozzle hole 122), and the nozzle 14 is made of metal. By providing the nozzle 14, on the one hand, the durability of the nozzle head 11 can be improved, and In order to avoid the service life of the nozzle 11 being reduced after spraying steam for a long time, on the other hand, after the cleaning spray gun 1 is added with a copper nozzle 14, the nozzle 14 can be used to increase the flow rate of the steam spray, increase the distance of the steam spray, and make the sprayed steam more concentrated, so that the steam is sprayed at a certain pressure, thereby improving the accuracy of the steam sprayed by the cleaning spray gun 1. In addition, since the nozzle 14 is made of metal, the purity of the steam (dry steam) can be maintained, and water droplets are avoided in the sprayed steam, which causes dripping from the nozzle 11, thereby improving the cleaning effect of the cleaning spray gun 1; specifically, the nozzle 14 is made of copper.

[0042] See also Figure 7 A control module 3 is provided in the main body 2, and the control module 3 is communicatively connected to the water supply device or the steam supply device; a control switch is provided on the control module 3, and the control switch is used to control the operation of the valve body of the water supply device (not shown in the figure) and the control valve of the steam supply device (not shown in the figure); by arranging the control module 3 on the main body 2, it is convenient for the user to operate the cleaning spray gun 1 to spray the fluid.

[0043] Specifically, in order to reduce the volume of the control module 3, the control module 3 is electrically connected to the water supply device or the steam supply device through a wire.

[0044] In this embodiment, the control switch includes a first switch 31 and a second switch 32. The first switch 31 is used to control the external device to output water to the first fluid channel 401, and the second switch 32 is used to control the external device to output steam to the second fluid channel 402. The control module 3 is provided with the first switch 31 and the second switch 32, so that the user can operate the first switch 31 and the second switch 32 respectively to control the external device to output fluid to the corresponding first fluid channel 401 and the second fluid channel 402. At the same time, by setting the first switch 31 and the second switch 32 with a gap between them, interference when the user operates the first switch 31 and the second switch 32 can be avoided, resulting in incorrect operation of the switches. In this embodiment, the second switch 32 is located above the first switch 31.

[0045] As another configuration of the control switch, the control switch is a multi-position push switch. By pushing the switch button to different positions, the external device is controlled to output steam to the first fluid channel or water to the second fluid channel. Although the description of this embodiment does not include a drawing of this configuration, this configuration still falls within the scope of protection of the present invention.

[0046] The control module 3 is provided with a safety switch 33, and the safety switch 33 is used to control the operation of the water supply device and the steam supply device.

[0047] When the safety switch 33 is in the locked state, the external device that can output water and generate steam is in the closed state; when the safety switch 33 is in the open state, the external device that can output water and generate steam is in the startable state; by setting the safety switch 33, the safety of the present invention can be improved, and it can be avoided that the cleaning spray gun 1 sprays fluid towards the user due to user's incorrect operation, causing injury to the user.

[0048] See also Figure 7 The main body 2 is detachably connected to the nozzle head 11. A first discharge channel 131 and a second discharge channel 132 are provided in the nozzle head 11. The outer end of the first discharge channel 131 is connected to the first nozzle hole 121, and the inner end is connected to the first fluid channel 401. The outer end of the second discharge channel 132 is connected to the second nozzle hole 122, and the inner end is connected to the second fluid channel 402.

[0049] By providing the first discharge channel 131 and the second discharge channel 132, a diversion effect can be played on the fluid output from the first fluid channel 401 and the second fluid channel 402, so that the fluid output from the first fluid channel 401 and the second fluid channel 402 can be stably ejected from the first nozzle 121 and the second nozzle 122. In addition, the provision of the first discharge channel 131 and the second discharge channel 132 makes it easier for production personnel to adjust the specifications of the first discharge channel 131 and the second discharge channel 132, thereby reducing the difficulty of assembling the first fluid channel 401, the second fluid channel 402 and the nozzle 11.

[0050] The calibers of the first discharge channel 131 and the second discharge channel 132 toward the outside of the cleaning spray gun 1 are smaller than the calibers thereof toward the inside of the cleaning spray gun 1 2 . By adopting the above-mentioned arrangement of the calibers of the first discharge channel 131 and the second discharge channel 132 , the speed at which the fluid is ejected from the first spray hole 121 and the second spray hole 122 can be increased, thereby improving the cleaning ability of the cleaning spray gun 1 .

[0051] As a configuration of the body 2, the body 2 includes a chamber 20 with a lower opening, and a connection hole 23 is provided at the upper end of the body 2 to communicate with the chamber 20. The first fluid channel 401 is a first tube 41, and the second fluid channel 402 is a second tube 42. The first tube 41 and the second tube 42 pass through the lower opening of the body 2 into the chamber 20 and are connected to the first discharge channel 131 and the second discharge channel 132, respectively. The body 2 adopts this configuration, which is simple in structure and low in cost. Moreover, because the first tube 41 and the second tube 42 are suspended relative to the interior of the chamber 20, heat generated by the fluid flowing through the first tube 41 and / or the second tube 42 is prevented from being transferred to the body 2, thereby preventing burns when the user holds the body 2. In addition, the first fluid channel 401 is the first tube 41, and the second fluid channel 402 is the second tube 42, which are independently arranged relative to the body 2. This can reduce the difficulty and cost of producing the cleaning spray gun 1, and facilitates the production personnel to select appropriate materials according to actual needs.

[0052] The first tube body 41 and the second tube body 42 are hoses made of high-temperature resistant soft material (such as silicone).

[0053] As another configuration of the body, the first and second fluid channels are integrally provided with the body, and the first and second fluid channels are hollow tubes provided on the body. Although the description of this embodiment does not include a drawing of this configuration, this configuration still falls within the scope of protection of the present invention.

[0054] See also Figures 3 to 5 、 Figure 7, also includes a first transfer channel connecting the first discharge channel 131 and the first tube body 41, and a second transfer channel connecting the second discharge channel 132 and the second tube body 42; the first transfer channel is formed by the internal channel of the first adapter 501, and the two ends of the first adapter 501 are respectively provided at the ports connecting the first discharge channel 131 and the first tube body 41; the second transfer channel is formed by the internal channel of the second adapter 502, and the two ends of the second adapter 502 are respectively provided at the ports connecting the second discharge channel 132 and the second tube body 42; the first adapter 501 and the second adapter 501 are an integral part, or the first adapter 501 and the second adapter 502 are independent parts; in this embodiment, the first adapter 501 and the second adapter 502 are arranged as an integral whole.

[0055] The first adapter 501 and the second adapter 502 are provided with an upper adapter nozzle 51 and a lower adapter nozzle 52 connected to the upper adapter nozzle 51. The first tube body 41 and the second tube body 42 are respectively connected to the corresponding lower adapter nozzle 52. The first discharge channel 131 and the second discharge channel 132 are respectively connected to the corresponding upper adapter nozzle 51.

[0056] See also Figure 5 The outer side wall of the lower end of the lower adapter nozzle 52 gradually shrinks downward. This arrangement makes it easier for production personnel to sleeve the first tube body 41 and the second tube body 42 on the lower adapter nozzle 52, thereby increasing the assembly speed.

[0057] See also Figure 5 A plurality of sealing members 53 are provided on the outside of the upper adapter nozzle 51. By providing the sealing members 53, the upper adapter nozzle 51 can be sealed with the first discharge channel 131 and the second discharge channel 132, thereby ensuring the sealing between the first adapter 5 and the nozzle 11, and preventing the fluid from leaking from the connection between the upper adapter nozzle 51 and the first discharge channel 131 and the second discharge channel 132.

[0058] See also Figure 3 The upper part of the main body 2 is provided with a mounting platform 22 for installing the nozzle 11. The nozzle 11 is arranged on the mounting platform 22. The connecting hole 23 is provided on the mounting platform 22. The upper adapter nozzle 51 is connected to the nozzle 11 through the connecting hole 23.

[0059] See also Figure 7 The outer side of the first adapter 5 is clamped with the inner side of the mounting platform 22, and an elastic member 50 is provided between the first adapter 5 and the bottom end of the mounting platform 22. The elastic member 50 is used to fill the gap between the first adapter 5 and the bottom end of the mounting platform 22, thereby improving the connection strength between the first adapter 5 and the main body 2 and preventing the first adapter 5 from shifting.

[0060] By providing the first adapter 501 and the second adapter 502, it is convenient for production personnel to quickly assemble the first fluid channel 401, the second fluid channel 402 and the nozzle 11, thereby reducing the production difficulty of the components of the present invention, improving the production speed, and reducing the production cost; in addition, the first adapter 501 and the second adapter 502 can fix the upper part of the first fluid channel 401 and the second fluid channel 402, thereby avoiding the first fluid channel 401 and the second fluid channel 402 from shifting during the use of the cleaning spray gun 1, resulting in unstable fluid output from the cleaning spray gun 1.

[0061] See also Figure 4 、 Figure 6 and Figure 7 The bracket 54 is assembled into the chamber 20 from the bottom side. A fixing structure is provided on the bracket 54 corresponding to the arrangement trajectory of the first tube body 41 and the second tube body 42. Specifically, the fixing structure includes a plurality of claws 55.

[0062] By providing the bracket 54 and providing a fixing structure for fixing the first tube body 41 and the second tube body 42 on the bracket 54, the structural strength of the first tube body 41 and the second tube body 42 can be improved. At the same time, the first tube body 41 and the second tube body 42 are prevented from shifting during the user's use of the cleaning spray gun 1, resulting in poor air supply to the first tube body 41 and the second tube body 42, thereby ensuring the reliability of the cleaning spray gun 1, and improving the smoothness of the fluid sprayed by the cleaning spray gun 1, thereby improving the cleaning effect.

[0063] See also Figure 4 and Figure 6 A fixing groove 56 is provided on the bracket 54 corresponding to the control module 3, and a plurality of fixing members 561 are provided on the fixing groove 56. The control module 3 is arranged on the fixing groove 56, and the fixing members 561 fix the outside of the control module 3; the main body 2 is provided with an air-avoiding hole 21 corresponding to the switch of the control module 3.

[0064] Specifically, the control module 3 is provided with button caps 34 corresponding to the first switch 31 , the second switch 32 and the safety switch 33 , and the button caps 34 can movably pass through the air-avoidance hole 21 .

[0065] The control module 3 is fixed by providing a fixing groove 56 on the bracket 54 , thereby preventing the control module 3 from shifting during use, making it easier for users to operate the control module 3 , increasing the response speed of the control module 3 , and improving the user experience.

[0066] See also Figure 6 and Figure 7, and also includes a sheath 24, which is arranged at the lower part of the body 2, and a protective hole 25 is provided in the middle of the sheath 24, and the input ports of the first fluid channel 401 and the second fluid channel 402 are located in the protective hole 25. The sheath 24 can protect the connection between the first fluid channel 401, the second fluid channel 402 and the external conduit, thereby preventing the connection between the first fluid channel 401, the second fluid channel 402 and the external conduit from loosening after being subjected to external impact; the protective hole 25 gradually shrinks downward, so that the production personnel can align the external conduit with the protective hole 25 and quickly connect the external conduit to the cleaning spray gun 1.

[0067] A collar 26 is provided at the lower portion of the bracket 54 , and the collar 26 is fixedly connected to the lower portion of the bracket 54 by screws. The sheath 24 is detachably mounted on the lower portion of the collar 26 . This arrangement ensures that the sheath 24 is securely mounted at the lower end of the body 2 .

[0068] Compared with the prior art, the cleaning spray gun 1 of the present invention has a first fluid channel 401 and a second fluid channel 402 and two corresponding first spray holes 121 and second spray holes 122. By being connected to an external device that can output water and generate steam, it can output clean water and steam to the outside, making it convenient for users to choose clean water or steam according to actual cleaning needs, and meet the needs of water flushing, steam cleaning or a mixed cleaning method of the above two for kitchen and bathroom appliances and facilities. In addition, when cleaning, the user holds the main body 2 of the cleaning spray gun 1 and aligns the first spray hole 121 and the second spray hole 122 with the kitchen and bathroom appliances and facilities to spray fluid in a direction, so as to clean the appliances and facilities. The operation is simple, and the user can be prevented from contacting the fluid, which is highly safe.

[0069] Example 2

[0070] See also Figures 8 to 9Another object of the present invention is to provide a cleaning device using the above-mentioned cleaning spray gun 1, which includes the cleaning spray gun 1 and a water heating mechanism 6; the water heating mechanism 6 includes a shell 65, a cover 66, a power supply and control module 67, a first water inlet valve 63, a second water inlet valve 61 and a steam generating device 62; the shell 65 is a hollow structure with an open end, the cover 66 is covered on the opening of the shell 65, and the power supply and control module 67, the first water inlet valve 63, the second water inlet valve 61 and the steam generating device 62 are arranged on the shell 65 Internally, the first water inlet valve 63, the second water inlet valve 61 and the steam generating device 62 are electrically connected to the power supply and control module 67, and the power supply and control module 67 is used to control the first water inlet valve 63, the second water inlet valve 61 and the steam generating device 62; the first water inlet valve 63 is arranged between the first fluid channel (not shown in the figure) and the water supply pipeline (not shown in the figure); the second water inlet valve 61 is arranged between the steam generating device 62 and the water supply pipeline, and the steam generating device 62 is connected to the other end of the second fluid channel (not shown in the figure).

[0071] Specifically, the steam generating device 62 is an instant steam generator, which produces a corresponding amount of steam after water is added. Therefore, a water pump 68 is provided between the second water inlet valve 61 and the steam generating device 62. The water pump 68 is used to control the amount of water entering the steam generating device 62. By providing a water pump 68 that is matched with the steam generating device 62, it is convenient to control the water inlet speed of the water pump 68, thereby accurately controlling the steam generation speed of the steam generating device 62, thereby maintaining the steam output of the steam generating device 62 stable and improving the steam output response speed, and can keep the cleaning effect in the best state.

[0072] A water softening device (not shown in the figure) is provided between the steam generating device 62 and the water supply pipeline. The water softening device is provided with an adsorption element for softening the water flowing into the steam generating device 62 .

[0073] Specifically, the adsorption element is an adsorption resin filled in the water softening device for adsorbing calcium ions and magnesium ions. The adsorption resin is a commonly used material in existing water softening treatment and is not the main invention of the present invention. The adsorption resin will not be described in detail here.

[0074] Scale accumulation in the steam generating device 62 will reduce the efficiency of the steam generating device 62 in generating steam, and may even cause the steam generating device 62 to explode, causing injury to the user. By providing a water softening device, metal ions (such as calcium and magnesium ions) in the water flowing into the steam generating device 62 can be removed, thereby avoiding the generation of scale when the steam generating device 62 generates steam, thereby extending the service life of the steam generating device 62 and improving the safety of the cleaning device.

[0075] The cleaning spray gun 11 and the water heating mechanism 6 are connected through a conduit assembly, which includes a plurality of conducting parts and a plurality of third adapters (not shown in the figure). One end of the conducting part is connected to the output port of the water heating mechanism 6, and the other end is connected to the cleaning spray gun 11 through the third adapter.

[0076] This setting method can make the relative distance between the cleaning spray gun 11 and the water heating mechanism 6 relatively adjustable. By increasing or decreasing the number of the conductive parts and the third adapter, the cleaning distance of the cleaning spray gun 20 can be increased. The setting is simple and convenient for users to use, thereby facilitating users to use the present invention in multiple scenarios. In addition, this setting method makes it convenient for users to install the present invention in a predetermined position according to actual conditions, avoiding the inability to install the present invention normally due to the relatively fixed relative distance between the cleaning spray gun 11 and the water heating mechanism 6.

[0077] As a setting mode of the conductive member, the conductive member includes two conduits 7, one of which is used to connect the steam generating device 62 and the second fluid channel of the cleaning spray gun 1, and the other conduit 7 is used to connect the first water inlet valve 63 and the first fluid channel of the cleaning spray gun 1.

[0078] As another arrangement of the conducting member, in order to save materials and avoid entanglement of the two conduits, the conducting member is a conduit with two pipes, the output end of the steam generating device 62 and the output end of the first water inlet valve 63 are respectively connected to one end of the two pipes of the conduit, and the two first fluid channels and the second fluid channels of the cleaning spray gun are respectively connected to the other end of the two pipes of the conduit; although the other arrangement of the conduit assembly is not shown in the drawings of this embodiment, this arrangement still falls within the scope of protection of the present invention.

[0079] The control module (not shown in the figure) on the cleaning spray gun 1 is in communication with the power supply and control module 67 of the water heating mechanism 6, thereby controlling the operation of the first water inlet valve 63, the second water inlet valve 61 and the steam generating device 62.

[0080] The first switch on the control module controls the first water inlet valve 63 to deliver water to the first fluid channel. The second switch on the control module 3 controls the second water inlet valve 61 and water pump 68 to deliver water to the steam generator 62 and to deliver steam to the second fluid channel. The safety switch on the control module 3 controls the operation of the water heating mechanism 6. When the safety switch is locked, the water heating mechanism 6 is disabled; when the safety switch is open, the water heating mechanism 6 is enabled.

[0081] Example 3

[0082] See alsoFigure 8 and Figure 10 This embodiment is an improvement of the second embodiment. The difference between this embodiment and the second embodiment is that a heating device 64 is connected between the first water inlet valve 63 and the cleaning spray gun 1.

[0083] A heating device 64 is provided in the water heating mechanism 6, and the heating device 64 is located between the first water inlet valve 63 and the cleaning spray gun 1. The water inlet end of the heating device 64 is connected to the first water inlet valve 63, and the water outlet end of the heating device 64 is connected to the first fluid channel (not shown in the figure).

[0084] Specifically, the heating device 64 may be an instant heating tube installed on a pipe, or may be an independently installed heat storage heater. In this embodiment, the heating device 64 is an instant heating tube installed on a pipe.

[0085] By setting up a heating device 64, the water flowing from the first water inlet valve 63 to the cleaning spray gun 1 can be heated, so that the water heating mechanism 6 can output normal temperature water (when the heating device 64 is not working) or hot water to the cleaning spray gun 1, so that the user can choose normal temperature water, hot water and steam for cleaning according to actual cleaning needs, thereby increasing the applicable scenarios of the cleaning device, and the cleaning effect of hot water is better than that of normal temperature water, thereby improving the cleaning effect of the cleaning device.

[0086] In this embodiment, when the safety switch 33 is in the open state, long pressing the safety switch 33 can cause the safety switch 33 to enter the locked state, and short pressing the safety switch 33 can cause the safety switch 33 to enter the switching function, switching the water characteristics output by the first fluid channel (not shown in the figure). Specifically, when the safety switch 33 is short pressed, the heating device 64 can be controlled by the program to work or not work, so that the first fluid channel outputs cold water and hot water.

[0087] Compared with the prior art, the cleaning device of the present invention has the following beneficial effects:

[0088] (1) The present invention is provided with a water heating mechanism 6 capable of outputting water and steam, and a cleaning spray gun 1 provided with a first fluid channel and a second fluid channel. By connecting the first fluid channel and the second fluid channel to a first water inlet valve 63 and a steam generating device 62, respectively, the cleaning spray gun 1 can be used in conjunction with the water heating mechanism 6, so that the cleaning device can output two different fluids, thereby facilitating the user to use clean water or steam to clean kitchen and bathroom appliances and facilities;

[0089] (2) When users use steam to clean and disinfect items at high temperatures, since steam disinfection does not require the use of detergents, detergent residues are avoided on the surface of the items. Steam disinfection can also be used for some kitchen and bathroom appliances and facilities that cannot be cleaned with water, thereby avoiding the situation where kitchen and bathroom appliances and facilities cannot be used normally after cleaning. In addition, steam can fully soften oil stains. Under the impact of the steam airflow, the oil stains can be quickly blown away and removed, thereby shortening the time spent by users on cleaning.

[0090] (3) The water input of the water heating mechanism 6 is connected to the water supply pipeline through a relatively independent water inlet valve, thereby ensuring that the components outputting different fluids can operate relatively independently, thereby improving work efficiency.

[0091] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are only for convenience of description and do not constitute any limitation to the present invention.
