Technical Field

[0001] The present invention relates to the technical field of floor scrubbers, and in particular to a spray head device and a floor scrubber. Background Art

[0002] With the development of economy and the progress of society, people have higher and higher requirements for the quality of life, so some intelligent appliances that can liberate manual work have come into being. Among them, floor scrubbers, as a kind of intelligent appliance, can clean hard floors and suck out sewage at the same time, and take the sewage away from the site, playing an increasingly important role in people's daily lives.

[0003] At present, household floor scrubbers are developing in the direction of small-sized and intelligent ones to meet the various needs of users. For the spray humidification function, the existing structure is to adjust the spray water volume through the electromagnetic pump design of multiple gears, and the water is sprayed to the roller brush to make the roller brush reach different degrees of humidity, and then the wet roller brush rotates to clean the dirt on the ground. However, in actual use, the floor conditions that need to be cleaned by the floor scrubber are various. If the amount of spray water is too much, the roller brush will be stained with too much water and affect the cleaning ability, and there will be more water stains after cleaning; if the amount of spray water is too little, it will lead to incomplete cleaning. Summary of the invention

[0004] In order to overcome at least one of the defects of the prior art described above, the present invention provides a spray head device and a floor scrubber.

[0005] The technical solution adopted by the present invention to solve the problem is as follows:

[0006] In a first aspect, the present invention discloses a nozzle device, comprising:

[0007] A spray head, the spray head is used to spray water onto the ground;

[0008] a water inlet member, the water inlet member being used to supply water to the spray head; and

[0009] The spray bracket supports the spray head and connects the spray head with the water inlet to achieve directional water spraying by the spray head.

[0010] In this way, on the basis of the original water of the floor brush of the floor scrubber spraying directly onto the roller brush, a nozzle device composed of a nozzle, a water inlet and a nozzle bracket is added to spray water on the ground in a direction. When it is necessary to clean a dirty ground or a ground that needs more water to be moistened, enough water can be sprayed in advance to moisten the ground in advance. The ground can be effectively cleaned subsequently, and excessive water can be avoided from being sprayed on the roller brush, so that the roller brush maintains a better cleaning ability.

[0011] Furthermore, a water passage is provided in the injection bracket, and the injection head is embedded in the water passage.

[0012] In this way, a water passage is provided in the spray bracket, which reduces the need for additional pipelines, simplifies the structure of the device, and facilitates manufacturing.

[0013] Furthermore, an annular groove is provided on the surface of the injection head, and a first sealing ring is connected in the annular groove so that the injection head is embedded in the water passage to form a seal.

[0014] In this way, the first sealing ring is used to seal the connection between the injection head and the water passage, so as to prevent water from leaking from the connection and enhance the stability of the injection head connected to the injection bracket.

[0015] Furthermore, a connecting pipe is provided on the water inlet member, one end of the connecting pipe is connected to the water passage, and a first sealing member for sealing and leak-proofing is provided at the connection between the connecting pipe and the water passage.

[0016] In this way, the first sealing member is used to seal the connection between the connecting pipe and the water passage to prevent water from leaking from the connection.

[0017] Furthermore, the other end of the connecting pipe is connected to the water inlet pipe, and a first filter element for filtering impurities in water and a second sealing element for preventing water leakage are provided at the connection between the water inlet pipe and the connecting pipe.

[0018] In this way, the second sealing member is used to seal the connection between the connecting pipe and the water inlet pipe to prevent water leakage from the connection, and the first filter is provided at the connection to filter impurities in the water, effectively isolating the impurities in the water and preventing the injection head from being blocked.

[0019] Furthermore, the nozzle device further comprises a nozzle cover plate, a trumpet-shaped groove is provided on the nozzle cover plate, the nozzle cover plate is connected to the nozzle bracket, and the nozzle head is inserted into the bottom of the groove.

[0020] In this way, when water is sprayed out through the spray head, it is easy to scatter over a larger range. By adding a spray head cover plate and limiting the spray range with the trumpet-shaped groove on it, the effect of directional spraying is achieved, avoiding increasing the amount of water on the ground in other areas and affecting the cleaning effect of the floor scrubber.

[0021] Furthermore, the water inlet pipe is connected to a water pump for pumping water from a water tank.

[0024] In this way, on the basis of the original water of the floor brush of the floor scrubber spraying directly onto the roller brush, a nozzle device composed of a nozzle, a water inlet and a nozzle bracket is added to spray water on the ground in a direction. When it is necessary to clean a dirty ground or a ground that needs more water to be moistened, enough water can be sprayed in advance to moisten the ground in advance. The ground can be effectively cleaned subsequently, and excessive water can be avoided from being sprayed on the roller brush, so that the roller brush maintains a better cleaning ability.

[0025] Furthermore, the spray head and the spray bracket of the spray head device are connected above the roller brush cover of the floor brush, and a spray structure for spraying water on the roller brush is connected below the roller brush cover;

[0026] The spray structure comprises a spray bracket connected to the roller brush cover and a spray member connected to the spray bracket, and the water inlet member is connected to the spray bracket.

[0027] In this way, the spray head and the spray bracket are both arranged above the roller brush cover, and can directly spray water onto the ground. The water inlet is arranged in the spray structure below the roller brush cover, which can simplify the structure and reduce space occupancy.

[0028] Furthermore, the floor brush is also provided with a control valve for controlling the flow direction of water from the water pump, and the control valve is respectively connected to the water inlet pipes of the spray element and the nozzle device.

[0029] In this way, the control valve combined with the water pump can realize water supply and spraying to the roller brush and control the water supply to the spray head to spray to the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0042] See also Figures 1 to 6 The present invention discloses a nozzle device, including a nozzle 1, a water inlet 2, a spray bracket 3 and a nozzle cover 8. The nozzle 1 is used to spray water on the ground; the water inlet 2 is used to supply water to the nozzle 1; the nozzle cover 8 is connected to the spray bracket 3, the spray bracket 3 supports the nozzle 1, and connects the nozzle 1 and the water inlet 2 to realize the directional spraying of water by the nozzle 1. In this way, on the basis of the original water of the floor brush of the floor scrubber directly spraying on the roller brush, by adding a nozzle device composed of the nozzle 1, the water inlet 2 and the spray bracket 3, the ground is sprayed with water in a directional manner, so that when it is necessary to clean a dirty ground or a ground that needs more water to be wetted, sufficient water is sprayed in advance to wet the ground in advance, so that the ground can be effectively cleaned in the subsequent process, and excessive water spraying on the roller brush is avoided, so that the roller brush maintains a good cleaning ability.

[0043] Specifically, see Figure 4 In the embodiment of the present invention, a water channel 301 is provided in the spray bracket 3, and the spray head 1 is embedded in the water channel 301. Conventional water supply is provided by laying pipes, but this makes the internal structure of the device more complicated. If a hose is used, it can be laid close to the components in the device, but the hose is easy to bend and clog, resulting in the inability to complete the water spraying action. The high-pressure water provided by the water pump will cause damage and leak at the weak position in the waterway, damaging the internal structure. Therefore, a water channel 301 is provided in the spray bracket 3 to reduce the number of additional pipes, simplify the structure of the device, and facilitate manufacturing.

[0044] See also Figure 2 and Figure 4 In the embodiment of the present invention, an annular groove 10181 is provided on the surface of the spray head 1, and a first sealing ring 4 is connected in the annular groove 10181, so that the spray head 1 is embedded in the water passage 301 to form a seal. Among them, the surface of the first sealing ring 4 in the embodiment of the present invention needs to be treated with acid and alkali resistance to prevent the user from adding weak acidic or weak alkaline water to the water tank in order to better clean the floor. Therefore, the first sealing ring 4 is used to seal the connection between the spray head 1 and the water passage 301 to prevent water from leaking from the connection, and can enhance the stability of the spray head 1 connected to the spray bracket 3.

[0045] In the embodiment of the present invention, refer to Figure 4 The water inlet 2 is provided with a connecting pipe 201, one end of which is connected to the water passage 301, and a first sealing member 5 for sealing and leak-proofing is provided at the connection between the connecting pipe 201 and the water passage 301. In the embodiment of the present invention, the first sealing member 5 is a threaded sleeve, which can increase the stability of the connection seal, and its surface needs to be treated with acid and alkali resistance to prevent users from adding weakly acidic or weakly alkaline water to the water tank in order to better clean the floor. Therefore, the first sealing member 5 is used to seal the connection between the connecting pipe 201 and the water passage 301 to prevent water from leaking from the connection. Figure 6 , the other end of the connecting pipe 201 is connected to the water inlet pipe (not shown in the figure), and the connection between the water inlet pipe and the connecting pipe 201 is provided with a first filter element 6 for filtering impurities in the water and a second seal element 7 for preventing water leakage. Among them, in the embodiment of the present invention, the first filter element 6 adopts a high-density filter mesh as an example, so as to isolate fine impurities in the water; the second seal element 7 in the embodiment of the present invention is a threaded kit, which can increase the stability of the connection seal, and its surface needs to be treated with acid and alkali resistance to prevent users from adding weak acidic or weak alkaline water to the water tank in order to better clean the floor. Therefore, the second seal element 7 is used to seal the connection between the connecting pipe 201 and the water inlet pipe to prevent water from leaking from the connection, and the first filter element 6 is provided at the connection to filter impurities in the water, effectively isolate impurities in the water, and prevent clogging of the injection head 1.

[0046] See also Figure 1In the embodiment of the present invention, a trumpet-shaped groove 81 is provided on the spray head cover plate 8, the spray head cover plate 8 is connected to the spray bracket 3, and the spray head 1 is penetrated at the bottom of the groove 81. Among them, the spray head 1 is exposed with a spray hole. As a preferred embodiment, the pipe diameter in the spray head 1 is arranged in a step-like manner. The closer to the spray hole, the smaller the pipe diameter. When the water encounters the step, a local recoil force will be formed, which can increase the spray pressure, so that the water can be stably sprayed for a corresponding distance before falling to the ground. In this way, the water will not fall on the roller brush cover 9, making the roller brush cover 9 wet. As another preferred embodiment, the pipe diameter in the spray head 1 is smaller as it approaches the spray hole, and finally the pipe diameter is equal to the spray hole. The spray hole is a section of equal diameter pipe. The water is continuously pressurized through the pipe in the spray head 1 until the spray hole stabilizes and then sprays out. The sprayed water flow is stable in a strip shape and reaches the destination surface away from the scrubber. In this way, the water will not fall on the roller brush cover 9, making the roller brush cover 9 wet. When water is sprayed out through the spray head 1, it is easy to scatter over a large area. By adding a spray head cover 8 and limiting the spray range with a trumpet-shaped groove 81 thereon, the effect of directional spraying is achieved, thereby avoiding increasing the amount of water on the ground in other areas and affecting the cleaning effect of the floor scrubber.

[0051] In the embodiment of the present invention, a control valve for controlling the water flow direction of the water pump is also provided in the floor brush, and the control valve is connected to the water inlet pipe of the spraying member 11 and the nozzle device respectively. The water pump is connected to the water tank through a water pipe to pump water, and then connected to the control valve through the water pipe. The water is diverted and controlled in the control valve, and then flows to the spray water inlet 1102 and / or the injection water inlet 1103 as required. The control valve combined with the water pump can realize water supply and spraying for the roller brush and control the water supply and injection of the nozzle head 1 to the ground.

[0052] See also Figure 2 In the embodiment of the present invention, a connecting structure is provided between the roller brush cover 9 and the spray bracket 10, and the connecting structure includes a clamping member 13, a limiting member 14 and an elastic member 15; the clamping member 13 can slide between the roller brush cover 9 and the spray; one end of the elastic member 15 is connected to the clamping member 13, and the other end is connected to the roller brush cover 9 or the spray bracket 10; a guide groove 1301 is provided on the clamping member 13, and the limiting member 14 is connected to the roller brush cover 9 or the spray bracket 10, so that the clamping member 13 can be clamped on the floor brush to form a stable detachable connection.

[0053] In the embodiment of the present invention, a switch is provided on the handle of the machine body, and the switch controls the opening and closing of the electromagnetic valve to realize the water supply of spraying and / or jetting.

[0054] For general floor cleaning, the water pump draws water from the water tank, and the water flows to the spray water inlet 1102 of the spray part 11 through the solenoid valve.
