Description

Technical Field

[0001] This utility model belongs to the field of sprayer technology, and specifically refers to a battery-detachable sprayer structure. Background Technology

[0002] Sprayers are common spraying tools. Most electric sprayers on the market now have their batteries installed at the bottom of the sprayer cylinder, which is bulky and inconvenient for charging, repairing, and replacing the batteries. The batteries also take up liquid storage space in the sprayer. Most sprayers on the market use lead-acid batteries. Because electric sprayers operate intermittently, batteries are easily damaged if they are not used for a long time or not charged in a timely manner. Since the battery is installed at the bottom of the cylinder, repairing and replacing the battery after it is damaged is extremely inconvenient, rendering the entire sprayer unusable. Summary of the Invention

[0003] The purpose of this invention is to provide a simple and reasonable structure for a battery-removable sprayer with a detachable battery installed inside the spray gun.

[0004] The purpose of this utility model is achieved as follows:

The spray gun contains a water pump, a nozzle, a water inlet connector, a circuit board, a battery, and a switch. The nozzle and the water inlet connector are connected to the water pump's inlet and outlet respectively via the water pipe. The battery, switch, and circuit board are connected to the water pump. The switch can control the water pump's on / off state, and the battery is detachably connected to the spray gun.

[0006] In the above-mentioned battery-detachable sprayer structure, the spray gun includes a left half shell and a right half shell, and a water inlet connector mounting groove, a nozzle mounting groove, a water pump mounting groove, and a battery receiving groove are respectively provided between the left half shell and the right half shell.

[0007] In the above-mentioned battery-detachable sprayer structure, elastic snap-fit ​​protrusions are provided on the left and right sides of the battery, and snap-fit ​​grooves that cooperate with the elastic snap-fit ​​protrusions are provided in the battery receiving groove.

[0008] In the above-described battery-detachable sprayer structure, an elastic plate is provided between the elastic snap-fit ​​protrusion and the battery, and the elastic snap-fit ​​protrusion is located at the end of the elastic plate.

[0009] In the above-described battery-detachable sprayer structure, the elastic plate is provided with anti-slip protrusions.

[0010] In the above-mentioned battery-detachable sprayer structure, the left and right halves of the shell are provided with palm receiving grooves, and the palm receiving grooves are provided with sealant sleeves.

[0011] In the above-mentioned battery detachable sprayer structure, the two ends of the caulking sleeve extend into the palm receiving groove, and the end of the sleeve protrudes outward to form a positioning ring, which is located between the left half shell and the right half shell.

[0012] In the above-mentioned battery-detachable sprayer structure, the cross-section of the sealant sleeve is a racetrack-shaped structure.

[0013] In the aforementioned battery-detachable sprayer structure, a lumbar support is provided on the backpack-type liquid storage tank.

[0014] In the aforementioned battery-detachable sprayer structure, the lumbar support fits snugly against the waist and is located at the lower end of the backpack-style liquid storage tank.

[0015] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0016] This utility model sprayer reduces the weight of the backpack-style liquid storage tank by detachably connecting the battery to the spray gun.

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1-6 The diagram shows a battery-detachable sprayer structure, comprising a backpack-style liquid storage tank 1 and a spray gun 2. The backpack-style liquid storage tank 1 and the spray gun 2 are connected by a water pipe. The spray gun 2 is equipped with a water pump 21, a nozzle 22, a water inlet connector 23, a circuit board, a battery 25, and a switch 26. The nozzle 22 and the water inlet connector 23 are respectively connected to the water inlet and outlet of the water pump 21 via water pipes. The battery 25, the switch 26, and the circuit board are connected to the water pump 21. The switch 26 can control the water flow. The pump 21 is switched on and off, and the battery 25 is detachably connected to the spray gun 2. By detachably connecting the battery to the spray gun, the weight of the backpack liquid storage tank can be reduced, and the battery of the spray gun can be replaced at any time. When the battery is out of power, another battery can be directly replaced. The battery is easy to install and remove. Compared with the prior art, even if the battery is damaged, it can be replaced in time. The operation is simple and the whole is lightweight. The water pipe in the figure is visible, and the connection between the spray gun and the backpack liquid storage tank is the prior art, which will not be described in detail here.

[0030] In the above-mentioned battery-detachable sprayer structure, the spray gun 2 includes a left half shell 201 and a right half shell 202. A water inlet connector mounting groove 203, a nozzle mounting groove 204, a water pump mounting groove 205, and a battery receiving groove 206 are respectively provided between the left half shell 201 and the right half shell 202. Specifically, this allows the water inlet connector, nozzle, water pump, and motor to be directly fixed, making installation relatively simple.

[0031] In the above-described battery-detachable sprayer structure, elastic snap-fit ​​protrusions 251 are respectively provided on the left and right sides of the battery 25, and snap-fit ​​grooves 252 that cooperate with the elastic snap-fit ​​protrusions 251 are provided in the battery receiving groove 206. An elastic plate 253 is provided between the elastic snap-fit ​​protrusions 251 and the battery 25, and the elastic snap-fit ​​protrusions 251 are located at the end of the elastic plate 253. Specifically, this is to facilitate the installation and removal of the battery.

[0032] In the above-mentioned battery-removable sprayer structure, the elastic plate 253 is provided with anti-slip protrusions 254. Specifically, this prevents fingers from sliding towards the anti-slip protrusions during the pressing process, ensuring that the battery can be removed stably.

[0033] In the aforementioned battery-detachable sprayer structure, a palm-accommodating groove 207 is provided on the left half-shell 201 and the right half-shell 202. A sealant sleeve 208 is provided inside the palm-accommodating groove 207. Both ends of the sealant sleeve 208 extend into the palm-accommodating groove 207, and a positioning ring 209 is formed by protruding outward from the middle end. The positioning ring 209 is located between the left half-shell 201 and the right half-shell 202. The cross-section of the sealant sleeve 208 is a racetrack-shaped structure. Specifically, this is to prevent fingers or palms from scratching the seam between the left and right half-shells and ensuring user comfort.

[0034] In the above-mentioned battery-detachable sprayer structure, a lumbar support 11 is provided on the backpack-type liquid storage tank 1. The lumbar support 11 fits snugly against the waist of the body and is located at the lower end of the backpack-type liquid storage tank 1. Specifically, this is to improve the comfort of use.

[0035] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model.
