Description

Technical Field

[0001] This utility model belongs to the field of sprayer technology and relates to a handheld sustainable sprayer. Background Technology

[0002] A sprayer is a portable container that sprays liquid in a mist form by manually pressing or squeezing. It is widely used in daily chemicals, pharmaceuticals, and horticulture. Generally, pressing the handle moves the piston downwards, reducing the space inside the pump head and increasing the pressure. At this time, the inlet valve closes and the outlet valve opens, allowing the liquid to spray out through the nozzle. Traditional sprayers rely on the instantaneous pressure generated by the pump head with each press; the pressure disappears when the handle is released, resulting in intermittent spraying and an inability to achieve continuous spraying. A single spray lasts only 1-2 seconds, making it inefficient for spraying cleaning agents over large areas and requiring frequent pressing. In response to this situation, a type of spray bottle has emerged on the market, such as the novel handheld pressurized sustainable spray bottle described in Chinese Patent No. "202510766961.1". The specific structure of this sprayer is as follows: it includes an outer shell; a top cover is installed on the top of the outer shell; a pressing handle is movably connected to the side of the outer shell near the top; a pump body is installed inside the outer shell; a piston is installed inside the pump body; a PET bottle containing the spray liquid is detachably connected to the lower end of the outer shell; a pressure storage mechanism communicating with the pump body is installed inside the outer shell; a spray outlet is opened on the side of the outer shell above the pressing handle; the pressure storage mechanism includes a pressure storage chamber located inside the outer shell; a spray pipe is fixedly connected to the outside of the pressure storage chamber; and an ultra-fine atomizing shutter mechanism is connected to the pressure storage chamber through the spray pipe. In the above structure, the pressure chamber can store the pressure generated by the pump body. Even if the handle is stopped, the pressure in the pressure chamber can still drive the liquid to spray continuously for 5-8 seconds. However, the spray time of 5-8 seconds is still far from the requirement of continuous spraying. There is still a defect that requires continuous or frequent pressing to spray a large area, which is not convenient to use. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a handheld, sustainable sprayer that is labor-saving and convenient to use.

[0004] The objective of this utility model can be achieved through the following technical solution: A handheld sustainable sprayer includes a housing and a nozzle. The housing contains a pump body, a contact switch, and a stop valve. The contact switch controls the operation of the pump body. The two ends of the stop valve are connected to a water tank and the pump body via connecting pipes. The pump body is connected to the nozzle. A push block is also slidably provided on the housing. The push block has a guide groove inside. The bottom of the guide groove is a guide slope. The top of the valve core of the stop valve contacts the guide slope, pushing the push block. The valve core moves under the guidance of the guide slope, connecting the water tank and the pump body. At the same time, the end of the push block squeezes the contact switch, causing the pump body to start running, and the liquid is sprayed out through the nozzle.

[0005] In the aforementioned handheld sustainable sprayer, a sliding cavity is provided on the inner wall of the housing, and a guide groove is formed on the outer wall of the housing. A strip-shaped hole communicating with the sliding cavity is formed in the guide groove. The housing includes a first housing and a second housing installed opposite to each other. The sliding cavity, the guide groove, and the strip-shaped hole are equally located on the first housing and the second housing. The push block includes a guide body, a guide plate, and a push protrusion located on the guide plate. The guide plate and the guide body are connected by a connecting block. The guide body is slidably disposed in the sliding cavity, the connecting block is slidably disposed in the strip-shaped hole, and the guide plate is slidably disposed in the guide groove, so that the push block is slidably mounted on the housing.

[0006] In the aforementioned handheld sustainable sprayer, the end of the push block is provided with a push plate, and the sliding cavity has a push hole on the side wall near the contact switch for the push plate to extend out of the sliding cavity. The contact switch includes an inclined contact pressure plate. The push block drives the push plate to move synchronously, and the push plate squeezes the contact pressure plate to deform the contact pressure plate, triggering the circuit to conduct and energizing the pump body to operate.

[0007] In the aforementioned handheld sustainable sprayer, a first limiting groove and a second limiting groove are formed on the side wall of the sliding cavity, and limiting strips are provided on both sides of the push block. When the limiting strip is inserted into the first limiting groove, the push block just presses the contact switch into place to make the circuit conduction; when the limiting strip is inserted into the second limiting groove, the push block disengages from the contact switch.

[0008] In the aforementioned handheld sustainable sprayer, positioning plates are provided at both ends of the push block, and positioning holes are formed on the side walls of the sliding cavity. The positioning plates slide within the positioning holes, and the positioning plates are in contact with the hole walls of the positioning holes.

[0009] The aforementioned handheld sustainable sprayer also includes a battery, a circuit board, and a charging port. The battery provides power to the operation of the pump body, the charging port charges the battery, and the contact switch controls the operation and shutdown of the pump body via the circuit board.

[0010] The aforementioned handheld sustainable sprayer also includes a sealing strip made of elastic material. The sealing strip has an insertion post on its side and a protruding ring in the middle of the insertion post. The second housing has a mounting hole and a charging hole. The insertion post and the protruding ring are both inserted into the mounting hole. The side of the protruding ring contacts the inner wall of the second housing, so that the sealing strip is installed on the second housing. The sealing strip covers the charging hole. The side of the sealing strip also has a pull strip.

[0011] In the aforementioned handheld sustainable sprayer, the stop valve includes a valve body, a valve core, a spring, a first sealing ring, and a second sealing ring. The valve body is provided with a first connecting pipe and a second connecting pipe, both of which are connected to the interior of the valve body. The first connecting pipe is connected to the water tank, and the second connecting pipe is connected to the pump body. The valve core is located inside the valve body, with its top extending out of the valve body and contacting the guide inclined surface. The valve core is provided with two first positioning rings and two second positioning rings. The first sealing ring and the second sealing ring are sleeved on the valve core, with the first sealing ring positioned above the second sealing ring and between the two first positioning rings. The second sealing ring is positioned between the two second positioning rings. The spring is sleeved on the tail of the valve core, with both ends of the spring abutting against the inner circumferential surface of the valve body and one of the second positioning rings, respectively. When the spring is in an extended state, the second sealing ring seals the connection between the second connecting pipe and the interior of the valve body.

[0012] In the aforementioned handheld sustainable sprayer, the pusher moves to cause the guide ramp to press against the valve core, the valve core moves downward, the spring is compressed, and when the valve core contacts the lower surface of the guide ramp, the second sealing ring disengages from the communication port between the second connecting pipe and the inside of the valve body, allowing the liquid inside the valve body to pass through the second connecting pipe to the pump body.

[0013] Compared with existing technologies, this handheld continuous sprayer connects the water tank and pump body by pushing the push block and triggers the contact switch to start the pump body. The liquid is sprayed out through the nozzle to achieve spraying. At this time, the cooperation of the limiting strip, the first limiting groove, the positioning plate and the positioning hole prevents the push block from moving automatically. Even if the push block can be positioned in the spraying state, it ensures continuous spraying without the need for continuous or frequent pressing. Only one push of the push block is needed to achieve continuous spraying, which is labor-saving and convenient to use, meets the needs of large-area spraying, and has high spraying efficiency. To turn off the spray, simply push the push block back. Using the push block to trigger the spray reduces the possibility of accidental activation due to external pressure. At the same time, the cooperation between the limiting strip, the second limiting groove, the positioning plate and the positioning hole prevents the push block from moving automatically and reduces interference from external forces.

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1-4 As shown, this handheld sustainable sprayer includes a housing 1 and a nozzle 7. The housing 1 contains a pump body 2, a contact switch 3, and a stop valve 4. The contact switch 3 controls the operation of the pump body 2. The two ends of the stop valve 4 are connected to a water tank and the pump body 2 via connecting pipes 6. The pump body 2 and the nozzle 7 are connected. A push block 5 is also slidably mounted on the housing 1. The push block 5 has a guide groove 51, the bottom of which is a guide slope 52. The top of the valve core 41 of the stop valve 4 contacts the guide slope 52. Pushing the push block 5 causes the valve core 41 to move under the guidance of the guide slope 52, connecting the water tank and the pump body 2. Simultaneously, the end of the push block 5 presses against the contact switch 3, causing the pump body 2 to start operating, and liquid is sprayed out through the nozzle 7.

[0021] In the above technical solution: a sliding cavity 11 is provided on the inner wall of the housing 1, and a guide groove 12 is formed on the outer wall of the housing 1. A strip hole 13 communicating with the sliding cavity 11 is formed in the guide groove 12. The housing 1 includes a first housing 18 and a second housing 19 installed opposite to each other. The sliding cavity 11, the guide groove 12, and the strip hole 13 are equally located on the first housing 18 and the second housing 19. The push block 5 includes a guide body 53, a guide plate 54, and a push protrusion 55 located on the guide plate 54. The guide plate 54 and the guide body 53 are connected by a connecting block 56. The guide body 53 is slidably disposed in the sliding cavity 11, the connecting block 56 is slidably disposed in the strip hole 13, and the guide plate 54 is slidably disposed in the guide groove 12, so that the push block 5 is slidably mounted on the housing 1.

[0022] In the above technical solution: the end of the push block 5 is provided with a push plate 57, and the sliding cavity 11 is provided with a push hole 14 on the side wall near the contact switch 3 for the push plate 57 to extend out of the sliding cavity 11. The contact switch 3 includes an inclined contact pressure plate 31. The push block 5 drives the push plate 57 to move synchronously. The push plate 57 squeezes the contact pressure plate 31 to deform the contact pressure plate 31, triggering the circuit to conduct and powering the pump body 2 to run.

[0023] In the above technical solution: a first limiting groove 16 and a second limiting groove 17 are formed on the side wall of the sliding cavity 11, and limiting strips 59 are provided on both sides of the push block 5. When the limiting strip 59 is engaged in the first limiting groove 16, the push block 5 is pressed into place by the contact switch 3 to make the circuit conduction; when the limiting strip 59 is engaged in the second limiting groove 17, the push block 5 is reset to place and disengages from the contact switch 3. The cooperation between the limiting strip 59 and the first limiting groove 16 and the second limiting groove 17 limits the movement of the push block 5, preventing the push block 5 from moving automatically after it has finished moving, and also preventing the push block 5 from moving excessively.

[0024] In the above technical solution: positioning plates 58 are provided at both ends of the push block 5, and positioning holes 15 are formed on both side walls of the sliding cavity 11. The positioning plates 58 slide within the positioning holes 15, and the positioning plates 58 and the hole walls of the positioning holes 15 are in contact. The friction between the positioning plates 58 and the hole walls of the positioning holes 15 plays an auxiliary positioning role for the push block 5 after it has moved, preventing the push block 5 from moving automatically. Currently, press-type handheld sprayers on the market are easily accidentally activated by external pressure during transportation or movement. By using the push block 5 to trigger the spray, the possibility of accidental activation by external pressure is reduced. At the same time, the cooperation between the limiting strip 59, the second limiting groove 17, the positioning plate 58, and the positioning holes 15 prevents the push block 5 from moving automatically, reducing interference from external forces.

[0025] The above technical solution also includes a battery 8, a circuit board 9, and a charging port 10. The battery 8 provides power for the operation of the pump body 2, the charging port 10 charges the battery 8, and the contact switch 3 controls the operation and shutdown of the pump body 2 through the circuit board 9.

[0026] The above technical solution also includes a sealing strip 101, which is made of an elastic material, such as rubber. The sealing strip 101 has an insertion post 102 on its side, and a protruding ring 103 in the middle of the insertion post 102. The second housing 19 has a mounting hole 191 and a charging hole 192. Both the insertion post 102 and the protruding ring 103 are inserted into the mounting hole 191, and the side of the protruding ring 103 contacts the inner wall of the second housing 19, allowing the sealing strip 101 to be installed on the second housing 19. The sealing strip 101 blocks the charging hole 192, preventing dust and impurities from the external environment from entering the charging port 10 and causing damage. The sealing strip 101 also has a pull strip 104 on its side, which allows the sealing strip 101 to be pulled outwards by hand, exposing the charging hole 192.

[0027] In the above technical solution: the stop valve 4 includes a valve body 42, a valve core 41, a spring 43, a first sealing ring 44, and a second sealing ring 48. The valve body 42 is provided with a first connecting pipe 47 and a second connecting pipe 49, both of which are connected to the interior of the valve body 42. The first connecting pipe 47 is connected to the water tank, and the second connecting pipe 49 is connected to the pump body 2. The valve core 41 is located inside the valve body 42, with its top extending out of the valve body 42 and contacting the guide inclined surface 52. The valve core 41 is provided with two first positioning rings 45 and two second positioning rings 46. The first sealing ring 44 and the second sealing ring 48 are fitted onto the valve core 41, with the first sealing ring 44 positioned above the second sealing ring 48 and between the two first positioning rings 45, and the second sealing ring 48 positioned between the two second positioning rings 46. Spring 43 is sleeved on the tail of valve core 41, with its two ends abutting against the inner circumferential surface of valve body 42 and one of the second positioning rings 46, respectively. When spring 43 is in the extended state, the second sealing ring 48 seals the communication port between the second connecting pipe 49 and the interior of valve body 42. The movement of push block 5 causes guide ramp 52 to press against valve core 41, causing valve core 41 to move downwards and spring 43 to be compressed. Figure 4 As shown, when the valve core 41 contacts the lower surface of the guide slope 52, the second sealing ring 48 disengages from the communication port between the second connecting pipe 49 and the inside of the valve body 42, allowing the liquid inside the valve body 42 to flow to the pump body 2 through the second connecting pipe 49. The first sealing ring 44 seals the top opening of the valve body 42 to prevent the liquid inside the valve body 42 from leaking from the valve body opening.

[0028] This handheld continuous sprayer connects the water tank and pump body 2 by pushing the push block 5 and triggers the contact switch 3 to start the pump body 2. The liquid is sprayed out through the nozzle 7 to achieve spraying. At this time, the cooperation of the limiting strip 59, the first limiting groove 16, the positioning plate 58, and the positioning hole 15 prevents the push block 5 from moving automatically. Even if the push block 5 can be positioned in the spraying state, it ensures continuous spraying without the need for continuous or frequent pressing. Only one push of the push block 5 is needed to achieve continuous spraying. It is labor-saving and convenient to use, meets the needs of large-area spraying, and has high spraying efficiency. To turn off the spray, simply push the push block 5 back. Using the push block 5 to trigger the spray reduces the possibility of accidental activation due to external pressure. At the same time, the cooperation between the limiting strip 59, the second limiting groove 17, the positioning plate 58, and the positioning hole 15 prevents the push block 5 from moving automatically and reduces interference from external forces.
