Description

Technical Field

[0001] This invention relates to a high-pressure cleaner, belonging to the field of cleaning equipment. Background Technology

[0002] High-pressure washers use a pressure unit to generate high-pressure water to rinse surfaces, clean gardens, or water plants. They are currently widely used in both industrial and daily life.

[0003] High-pressure washers typically consist of a pressure unit, a support bracket for the pressure unit, and a hose reel mounted on one side of the bracket. The hose reel and pressure unit are usually separate, requiring connection each time the machine is used, which is cumbersome. To address this issue, existing technology fixes the pressure unit and hose reel within the same housing. However, in this structure, since both the hose reel and pressure unit are fixed together, and the pressure unit contains electrical control components, a waterproof structure is needed to isolate the pressure unit and hose reel to ensure the lifespan of these components. However, because the pressure unit requires external airflow for cooling, this waterproof structure needs a certain degree of permeability. But since the pressure unit operates in a high-humidity environment, moisture will enter the pressure unit during cooling. Over time, this accumulated moisture will cause the electrical control components to malfunction, thus reducing the lifespan of the pressure unit. Summary of the Invention

[0004] The purpose of this invention is to provide a high-pressure cleaner that can meet the dual requirements of heat dissipation and waterproofing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-pressure cleaner, comprising: chassis; A pressure unit assembly includes a chamber installed within the housing, a pressure unit housed within the chamber, and a connector installed at the inlet of the pressure unit; and The hose is housed inside the housing via a rotating structure, with the free end of the hose located outside the housing and the fixed end of the hose connected to the pressure unit. The chamber contains a receiving cavity for accommodating at least a portion of the pressure unit, and an air inlet cavity and an air outlet cavity distributed on the side of the receiving cavity. An airflow baffle is formed in the air inlet cavity. After external airflow enters the air inlet cavity, it first flows through the airflow baffle and then enters the receiving cavity. An air inlet cavity is formed on the chamber to allow external airflow to enter the air inlet cavity and an air outlet cavity to connect the air outlet cavity with the outside.

[0006] Furthermore, the hopper includes a hopper shell and a partition plate formed within the hopper shell. The partition plate includes a U-shaped plate and an extension plate extending approximately vertically outward from both sides of the U-shaped plate. The U-shaped plate surrounds the storage cavity, and the air inlet cavity and air outlet cavity are located on both sides of the extension plate.

[0007] Furthermore, a retaining opening is formed at the lower part of the U-shaped plate, the pressure unit is secured in the retaining opening, and the lower part of the pressure unit protrudes out of the receiving cavity and is located in the air intake cavity.

[0008] Furthermore, a water-blocking part is formed inside the housing corresponding to the air outlet and air inlet. In the opening direction of the air outlet and air inlet, and in the direction of the placement plane of the high-pressure cleaner, the projection of the water-blocking part and the air outlet and air inlet is located inside the corresponding air outlet and air inlet or blocks the air outlet or air inlet.

[0009] Furthermore, the chamber has an end wall exposed outside the housing, and a through hole is formed on the end wall. An arc-shaped groove extending circumferentially from one side of the through hole is formed on the inner side of the end wall. The depth of the arc-shaped groove gradually decreases as it moves away from the through hole. The pressure unit assembly also includes a cable. One end of the cable enters the chamber through the through hole to be electrically connected to the pressure unit. The portion of the cable located in the chamber near the through hole is pressed against the arc-shaped groove by a pressure block.

[0010] Furthermore, an annular groove is formed on the outer side wall of the chamber, and the pressure unit assembly also includes a cable electrically connected to the pressure unit, with the portion of the cable outside the chamber wound around the chamber and located within the annular groove.

[0011] Furthermore, the housing is provided with several cable gathering handles, which can move relative to the annular groove to press the cable against the annular groove.

[0012] Furthermore, the chamber has an end wall exposed outside the housing, an interface is formed on the end wall, the axis of the interface overlaps with the axis of the chamber, and the connector includes a connector seat that mates with the pressure unit and a mating part mounted on the connector seat for connection with the outside, the connector seat being secured within the interface.

[0013] Furthermore, the rotating structure includes a chamber that is rotatable relative to the housing, the pressure unit is fixed in the chamber, and the portion of the hose wound around the chamber is located between the chamber and the housing.

[0014] Furthermore, the housing is generally square, and at least one upper corner of the housing is recessed to form an accessory holder for inserting the free end of an accessory or hose.

[0015] The beneficial effects of this invention are as follows: The high-pressure washer of this application achieves isolation between the pressure unit and the hose by arranging the pressure unit inside the chamber. Furthermore, by forming a receiving cavity, an air inlet cavity, and an air outlet cavity inside the chamber, airflow isolation is achieved within the chamber, preventing turbulence when the airflow moves within the chamber. In addition, the airflow baffle in the air inlet cavity achieves gas-liquid separation of water vapor in the airflow after it enters the chamber, preventing water vapor in the airflow from entering the pressure unit, thereby achieving the dual requirements of heat dissipation and waterproofing.

[0016] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, the preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0019] Please see Figures 1 to 3 The high-pressure washer 10 shown in a preferred embodiment of this application includes a housing 1, a pressure unit assembly 2 disposed within the housing 1, a hose 3 housed within the housing 1, and a switch 4 for controlling the operation of the pressure unit 22 (described later) (see [link to application]). Figure 2 The pressure unit assembly 2 includes a chamber 21 installed within the housing 1, a pressure unit 22 housed within the chamber 21, and a connector 23 installed on the inlet of the pressure unit 22. The chamber 21 contains a receiving cavity 211 for accommodating at least a portion of the pressure unit 22, and an air inlet cavity 212 and an air outlet cavity 213 distributed on the sides of the receiving cavity 211. An airflow baffle 214 is formed within the air inlet cavity 212. External airflow enters the air inlet cavity 212, flows through the airflow baffle 214, and then enters the receiving cavity 211. The chamber 21 has an air inlet 2151 for allowing external airflow to enter the air inlet cavity 212 and an air outlet 2152 for connecting the air outlet cavity 213 to the outside.

[0020] The high-pressure washer 10 isolates the pressure unit 22 from the hose 3 by arranging the pressure unit 22 inside the chamber 21. Furthermore, it isolates the airflow within the chamber 21 by forming a receiving cavity 211, an air inlet cavity 212, and an air outlet cavity 213, ensuring that the airflow does not become turbulent when moving within the chamber 21. In addition, the airflow baffle 214 in the air inlet cavity 212 separates the water vapor in the airflow after it enters the chamber 21, preventing the water vapor in the airflow from entering the pressure unit 22. This achieves both heat dissipation and waterproofing.

[0021] In this embodiment, the high-pressure washer 10 has a generally square housing structure. Specifically, the housing 1 is generally square, with opposing square walls 11 and a connecting wall 12 connecting the two square walls 11, one of which has an opening 131. The square walls 11 are provided with mounting windows 111 for mounting end walls 210 of the chamber 21. The chamber 21 is a flattened cylindrical body, horizontally mounted on the housing 1. The chamber 21 has two end walls 210 mounted on the mounting windows 111, which are exposed outside the housing 1. The hose 3 is retracted into the housing 1 via a rotating structure, with the free end 31 of the hose 3 protruding through the opening 131 to be located outside the housing 1. The fixed end (unlabeled) of the hose 3 is connected to the pressure unit 22.

[0022] In a preferred embodiment, the chamber 21 is rotatable relative to the housing 1. This rotating structure includes a chamber 21 rotatable relative to the housing 1, a pressure unit 22 fixed inside the chamber 21, and a portion of the hose 3 wound around the chamber 21 located between the chamber 21 and the housing 1. Specifically, this rotating structure may include: annular grooves (not shown) formed on the sides of the end walls 210 of the chamber 21; and annular sliders (not shown) formed on the mounting window 111 that can be inserted into the annular grooves. The engagement of the annular grooves and the annular sliders allows the chamber 21 to rotate relative to the housing 1.

[0023] To facilitate the rotation of the chamber 21, a handle 51 is formed on one end wall 210 of the chamber 21. The handle 51 is offset to one side of the rotation axis of the chamber 21. The handle 51 facilitates the application of force to drive the chamber 21 to rotate, thereby enabling the hose 3 to be wound around the chamber 21.

[0024] Different types of accessories, such as a spray gun (not shown), can be fitted to the free end 31 of the hose 3 according to usage requirements. For easy storage, an accessory rack 132 is recessed at at least one upper corner of the housing 1 to allow insertion of the accessory or the free end 31 of the hose 3. This accessory rack 132 secures the inserted accessory or the free end 31 of the hose 3 for easy storage. Positioning the accessory rack 132 at the upper corner of the housing 1 also helps to fully utilize the unused space within the housing 1. Furthermore, the angle formed between the insertion direction of the free end 31 of the accessory or hose 3 relative to the accessory rack 132 and the placement plane of the high-pressure washer 10 is between 65° and 90°. This arrangement not only fully utilizes the space of the housing 1 but also facilitates insertion and removal, conforming to operational habits. Along the height direction of the high-pressure washer 10, the opening of the accessory rack 132 gradually decreases from top to bottom.

[0025] Please combine Figures 3 to 5 The chamber 21 includes a chamber shell 217 horizontally mounted on the housing 1 and a partition plate 218 formed within the chamber shell 217. The partition plate 218 includes a U-shaped plate 2181 and an extension plate 2182 extending approximately vertically outward from both sides of the U-shaped plate 2181. Specifically, the U-shaped plate 2181 has a lower portion 2181a and side portions 2181b extending upward from both ends of the lower portion 2181a. The extension plate 2182 extends from the side portions 2181b toward the side wall of the chamber shell 217 and connects to the side wall of the chamber shell 217. The U-shaped plate 2181 encloses a receiving cavity 211, and an air inlet cavity 212 and an air outlet cavity 213 are located on both sides of the extension plate 2182. The U-shaped plate 2181 divides the interior of the chamber 21 into the receiving cavity 211, the air inlet cavity 212, and the air outlet cavity 213, which has a simple structure and is easy to implement. Furthermore, since extension plates 2182 are formed on both sides of the U-shaped plate 2181, there are two air inlet chambers 212 and two air outlet chambers 213, which helps to improve heat dissipation performance. Air inlets 2151 and 2152 are formed on the end walls 210 of the housing 217, and are arc-shaped segments extending circumferentially from both sides of the extension plates 2182. An airflow baffle 214 is located between the air inlet 2151 and the U-shaped plate 2181. This airflow baffle 214 extends from one side of the extension plates 2182 toward the side wall of the housing 217 and connects with the housing 217.

[0026] The U-shaped plate 2181, the extended plate 2182, and the airflow baffle 214 are formed between the two end walls 210. In this embodiment, the housing 21 is a half structure, and the parting surface of the housing 21 is perpendicular to the axis of the housing. The U-shaped plate 2181, the extended plate 2182, and the airflow baffle 214 each consist of two parts symmetrically arranged on the two end walls 210. After the housing 21 is assembled, the two parts of the U-shaped plate 2181 and the extended plate 2182 are joined together, and the two parts of the airflow baffle 214 are not completely joined together, forming a gap, thereby forming an airflow port (not shown). This airflow port is located on one side of the side portion 2181b, and the airflow in the air intake chamber 212 enters the receiving chamber 211 through the airflow port.

[0027] The housing 21 has a water-blocking portion 216 formed inside, corresponding to the air outlet 2152 and air inlet 2151. In the direction of the placement plane of the high-pressure washer 10, the projections of the water-blocking portion 216 onto the air outlet 2152 and air inlet 2151 are located within or block the corresponding air outlet 2152 or air inlet 2151. The water-blocking portion 216 prevents water from splashing into the housing 21. This water-blocking portion 216 is located inside the end wall 210, specifically within the corresponding air inlet chamber 212 and air outlet chamber 213.

[0028] In this embodiment, the airflow baffle 214 is partially formed on the inner water-blocking portion 216, which is the water-blocking portion 216 closest to the U-shaped plate 2181 among all water-blocking portions. The water-blocking portion 216 includes a blocking portion 216a that blocks the air outlet 2152 and the air inlet 2151 in the direction of the placement plane of the high-pressure washer 10, and a covering portion 216b extending from one side of the blocking portion 216a toward the end wall 210. An opening 2151a on one side of the air inlet 2151 is formed between the blocking portion 216a and the end wall 210, and the orientation of the opening 2151a is away from the U-shaped plate 2181.

[0029] In this embodiment, the airflow baffles 214 are arranged symmetrically in the air inlet chamber 212 and the air outlet chamber 213. Of course, in other embodiments, the airflow baffles 214 may only be formed in the air inlet chamber 212. A plurality of water outlet holes (not shown) are provided at the edge of the end wall of the chamber housing 21, so that the water vapor blocked by the airflow baffles 214 will be collected and flow out from the water outlet holes to prevent it from entering the pressure unit 22.

[0030] To facilitate the fixing of the pressure unit 22, in this embodiment, the pressure unit 22 is secured within the housing 217 by a U-shaped plate 2181. Specifically, the U-shaped plate 2181 has several fixing plates 2183 connecting the two side portions 2181b. The fixing plates 2183 are approximately parallel to the lower portion 2181a. Both the fixing plates 2183 and the lower portion 2181a have retaining openings 2184. The pressure unit 22 is secured within the retaining openings 2184. The lower part of the pressure unit 22 protrudes from the receiving cavity 211 and is located within the air inlet cavity 212. This arrangement also allows the pressure unit 22 to be partially located within the air inlet cavity 212, facilitating airflow into the pressure unit 22 and thus achieving cooling of the pressure unit 22.

[0031] As mentioned above, the chamber 21 has two oppositely arranged end walls 210, which are the first end wall and the second end wall of the chamber shell 217. In order to ensure the safety of the high pressure washer 10, the connector 23 is fixed on the first end wall and the switch 4 is fixed on the second end wall.

[0032] Please combine Figure 1 , Figure 2 and Figure 6 In this embodiment, the connector 23 is arranged as follows: an interface 210a is formed on the end wall 210, and the axis of the interface 210a overlaps with the axis of the housing 214. The connector 23 includes a connector seat 231 that mates with the pressure unit 22 and a mating part 232 mounted on the connector seat 231 for external connection. The connector seat 231 and the mating part 232 are threaded together. In this embodiment, the connector 23 is preferably a rotary connector. The connector seat 231 is secured within the interface 210a. Specifically, a protrusion (not labeled) is formed on the side wall of the connector seat 231, and an L-shaped groove 210b matching the protrusion is formed on the side wall of the interface 210a. The axis of the pressure unit 22 is perpendicular to the axis of the housing 214.

[0033] During implementation, the pressure unit 22 can be a swashplate plunger pump as shown in the instruction manual, or a membrane pump or other technical solutions to meet the needs of high flow rates, depending on the application scenario. The pressure unit assembly 2 also includes a power supply unit. In one embodiment, the power supply unit is a cable 6 electrically connected to the pressure unit 22; in another embodiment, the power supply unit is a built-in battery pack with a charging port electrically connected to the battery pack on the second side wall where the switch 4 is located, for charging the battery pack.

[0034] Please combine Figures 3 to 5In this embodiment, cable 6 is used to supply power to the pressure unit 22 via an external AC power supply. A through-hole 2101 is formed on the end wall 210, and an arc-shaped groove 2102 extending circumferentially from one side of the through-hole 2101 is formed on the inner side of the end wall 210. The depth of the arc-shaped groove 2102 gradually decreases as it moves away from the through-hole 2101. One end of cable 6 enters the chamber 21 through the through-hole 2101 to electrically connect with the pressure unit 22. The portion of cable 6 located inside the chamber 21 near the through-hole 2101 is pressed against the arc-shaped groove 2102 by the wire pressing block 219. By arranging the through-hole 2101 of cable 6 on the end wall 210 and pressing the cable 6 against the arc-shaped groove 2102 by the wire pressing block 219, the through-hole 2101 is avoided on the housing 1 while ensuring the cable 6's fixing strength, and this also helps improve waterproofing.

[0035] Please see Figure 3 and Figure 7 To facilitate the storage of the cable 6, an annular groove 2103 is formed inward on the end wall 210. The portion of the cable 6 outside the housing 21 is wound around the housing 21 and located within the annular groove 2103. Furthermore, the housing 21 is provided with several cable gathering handles 52, which can move relative to the annular groove 2103 to press the cable 6 against the annular groove 2103.

[0036] When cable 6 is needed, rotate the cable hub handle 52 so that the projection of the cable hub handle 52 is not located in the annular groove 2103. At this time, the cable hub handle 52 no longer presses against the cable 6, so that the cable 6 located in the annular groove 2103 can be taken out smoothly. When cable 6 needs to be stored, wind the cable 6 into the annular groove 2103, and then drive the cable hub handle 52 to rotate so that the projection of the cable hub handle 52 is located in the annular groove 2103. Thus, the cable 6 is pressed against the annular groove 2103 by the cable hub handle 52 to prevent the cable 6 from coming loose.

[0037] It should be noted that, as mentioned above, the cable 6 is fixed in the wire hole 2101 by the setting of the arc-shaped groove 2102 and the wire pressing block 219. Since the arc-shaped groove 2102 is arranged circumferentially and the depth gradually decreases as it moves away from the wire hole 2101, the cable 6 is arranged at an angle in the wire hole 2101. That is, the axial direction of the cable 6 in the wire hole 2101 extends approximately circumferentially. This makes it easier for the cable 6 to be folded and reduces the bending of the cable 6.

[0038] Since the cable 6 and hose 3 are both wrapped around the chamber 21, and the pressure unit 22 is fixed inside the chamber 21, the high-pressure washer 10 is integrated into one unit, making it portable and easy to use. A soft handle 53 is provided on the upper side wall of the housing 1 to facilitate the movement of the high-pressure washer 10.

[0039] Please combine Figure 4 , Figure 7 and Figure 8 In this embodiment, an assembly groove 210c for mounting the cable hub handle 52 is formed on the end wall 210. The sidewall of the assembly groove 210c has a toothed structure. The cable hub handle 52 includes a handle portion 521 and a plug portion 522 extending from one sidewall of the handle portion 521. The plug portion 522 is arranged perpendicularly to the handle portion 521. The plug portion 522 is inserted into the assembly groove 210c. The plug portion 522 is formed by a plurality of plate-shaped hook portions 5221, and a protrusion 5222 is formed on the side of the plate-shaped hook portions 5221. When the plug portion 522 is assembled into the assembly groove 210c, the cable hub handle 52 can rotate relative to the assembly groove 210c. The cable hub handle 52 is fixed in the non-rotating state by the cooperation of the protrusion 5222 and the toothed structure.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
