Description

Technical Field

[0001] This utility model relates to the field of lithium battery water gun technology, and in particular to a water-cooled lithium battery water gun. Background Technology

[0002] A lithium battery-powered high-pressure water gun is a portable high-pressure cleaning device powered by a built-in lithium battery. Its core function is to generate high-pressure water flow by driving a water pump with a motor, achieving a stronger cleaning effect than ordinary water pipes.

[0003] The specific structure of a handheld cleaning machine is proposed in publication number CN207413658U, entitled "A Handheld Cleaning Machine". The machine uses the water that is already being supplied to cool the motor, eliminating the need for additional water for cooling, thus saving water and making the structure compact.

[0004] However, there is another problem with the above-mentioned patent. After passing through the motor, the water directly enters the flow channel. Although the water passes through the motor, it does not circulate around the motor before entering the flow channel. The contact time between the water and the motor housing is relatively short. At the same time, the water flow rate is fast in some places and slow in others, which may lead to a certain degree of "dead zone" and stagnation. When the lithium battery water gun is working fully, the water directly enters the flow channel after passing through the motor, which limits the heat dissipation effect. Utility Model Content

[0005] In view of the above-mentioned problems, the technical problem to be solved by this utility model is to provide a water-cooled lithium battery water gun.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a water-cooled lithium battery water gun, including a gun body, a detachable lithium battery on the outside of the gun body, a water outlet pipe and a water inlet pipe fixedly disposed with the gun body, a flow channel inside the gun body for connecting the water outlet pipe and the water inlet pipe, a plunger pump and a motor installed inside the gun body, the motor being used to drive the plunger pump to work, a cavity for connecting the water inlet pipe and the flow channel installed inside the gun body, the motor being installed inside the cavity, a detachable inner sleeve layer installed inside the cavity, the inner sleeve layer having a threaded thread layer inside, the inner side of the threaded layer being pressed against the outer wall of the motor, and a water outlet opening on the outer wall of the inner sleeve layer communicating with the flow channel, so that water moves from the water inlet pipe to the inner sleeve layer, and from the water outlet to the flow channel.

[0007] A further preferred embodiment of this utility model is: the inner sleeve is thin-walled and fits against the inner wall of the cavity, and is circular in shape with extended edges at the upper and lower ends respectively;

[0008] The motor housing has multiple rings arranged in a single piece, with a sealing ring between each ring. The sealing rings are pressed against the inner wall of the cavity. There is also a sealing ring between the upper extension edge of the inner sleeve and the lowest ring, and a sealing gasket between the lower extension edge of the inner sleeve and the inner wall of the cavity.

[0009] A further preferred embodiment of this utility model is: the inner wall of the lower end of the cavity has a mounting groove, and a sealing gasket is installed in the mounting groove.

[0010] A further preferred embodiment of this utility model is as follows: the lower end of the cavity has an integrally formed support layer, there are multiple support layers and they are distributed around the cavity axis. The support layer is "L" shaped. The lower end of the motor protrudes outward and passes through the inner sleeve and is sandwiched between the multiple support layers. The protruding part of the lower end of the motor abuts against the support layer. There is a water inlet gap between the lower end of the motor and the lower extension edge of the inner sleeve.

[0011] A further preferred embodiment of this utility model is that the motor housing is sealed and waterproof.

[0012] A further preferred embodiment of this utility model is: the threaded layer is also made of metal and is integrally set on the inner wall of the inner sleeve layer. The threaded layer spirals upward, so that the water passing outside the motor moves in a spiral motion.

[0013] A further preferred embodiment of this utility model is that the inner sleeve layer and the threaded layer are made of aluminum.

[0014] A further preferred embodiment of this utility model is: a second sealing gasket is provided on the inner side of the threaded layer, the second sealing gasket being spirally raised along the threaded layer and pressed against the outer wall of the motor.

[0015] A further preferred embodiment of this utility model is: a frame edge is integrally formed on the side of the threaded layer facing inward, the frame edge spirals upward along the threaded layer, and the sealing gasket is clamped inside the frame edge and squeezed against the inner wall of the frame edge.

[0016] A further preferred embodiment of this utility model is: the frame edge is made of aluminum with a C-shaped cross-section, used to limit the sealing gasket.

[0017] Compared with the prior art, the advantages of this utility model are:

[0018] 1. Water enters between the motor and the inner sleeve layer. The inner sleeve layer has a threaded layer. The water moves spirally along the threaded layer, which increases the contact time between the water and the motor housing. The forced spiral flow prevents heat from accumulating in certain areas of the motor surface. There are no stagnant areas, and the water can more fully and efficiently remove the heat generated during the operation of the motor.

[0019] 2. The upper and lower ends of the inner sleeve are sealed by sealing rings and sealing gaskets, which strictly restricts the flow of water within the inner sleeve and the spiral channel between it and the motor housing, preventing water leakage. At the same time, when the internal channel of the inner sleeve becomes narrowed due to scale, affecting the flow rate or heat dissipation efficiency, the entire inner sleeve can be easily removed and replaced.

Detailed Implementation

[0029] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0030] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0031] This embodiment mainly describes a water-cooled lithium-ion battery water gun. Please refer to [link / reference]. Figures 1-7 Specifically, water enters the flow channel 5 directly after passing through motor 7. Although the water passes through motor 7, it does not circulate around motor 7 before entering the flow channel 5, resulting in a certain stagnation area around motor 7. To address this issue, a water-cooled lithium-ion battery water gun is proposed, such as... Figures 1-6 As shown, the gun includes a gun body 1, a detachable lithium battery 2 on the outside of the gun body 1, a water outlet pipe 3 and a water inlet pipe 4 fixedly installed with the gun body 1, and a flow channel 5 inside the gun body 1 for connecting the water outlet pipe 3 and the water inlet pipe 4. A plunger pump 6 and a motor 7 are also installed inside the gun body 1. The motor 7 is used to drive the plunger pump 6 to work. A cavity 8 for connecting the water inlet pipe 4 and the flow channel 5 is also installed inside the gun body 1. The motor 7 is installed in the cavity 8. A detachable inner sleeve 9 is also installed inside the cavity 8. The inner sleeve 9 has a threaded layer 94 inside. The inner side of the threaded layer 94 is pressed against the outer wall of the motor 7. The outer wall of the inner sleeve 9 has a water outlet 91 that communicates with the flow channel 5, so that water moves from the water inlet pipe 4 to the inner sleeve 9 and from the water outlet 91 to the flow channel 5.

[0032] Specifically, the gun body 1, the lithium battery 2 connected to the outside of the gun body 1, the water outlet pipe 3, the water inlet pipe 4, and the plunger pump 6 and motor 7 that drive the action are all existing technologies and will not be described in detail here. The movement of water driven by the plunger pump 6 controlled by the motor 7 is also existing technology. At the same time, the outer shell of the motor 7 is sealed to prevent water from entering the motor 7 when water passes through the outside of the motor 7, thus preventing water from carrying away the heat generated by the motor 7. It should be noted that the threaded layer 94 is designed so that water can move along the threaded layer 94, avoiding the formation of a stagnant area on the outside of the motor 7.

[0033] like Figure 5 The inner sleeve 9 is further explained as shown. The inner sleeve 9 is thin-walled and fits against the inner wall of the cavity 8. It is circular and has an extension edge 92 at the top and bottom ends.

[0034] The outer shell of the motor 7 has multiple rings 71 arranged in a single piece. Each ring 71 is fitted with a sealing ring 72. The sealing rings 72 are pressed against the inner wall of the cavity 8. There is also a sealing ring 72 between the upper extension edge 92 of the inner sleeve layer 9 and the lowermost ring 71. There is a sealing gasket 93 between the lower extension edge 92 of the inner sleeve layer 9 and the inner wall of the cavity 8.

[0035] Specifically, the outer casing of the motor 7 and the cavity 8 have a sealing ring 72 to prevent water from moving along the axis of the motor 7 and causing water leakage. In addition, the inner sleeve 9 has extension edges 92 at both the upper and lower ends, and the outer sides of the extension edges 92 at both ends have sealing rings 72 and sealing gaskets 93, so that the upper and lower ends of the inner sleeve 9 are sealed. Water can only move from the bottom into the inner sleeve 9 and out from the outlet 91, so that water passes through the outside of the motor 7 but does not leak. It should also be noted that since the inner sleeve 9 is sealed by the sealing rings 72 and sealing gaskets 93, it is easy to replace the inner sleeve 9, sealing rings 72 and sealing gaskets 93 during disassembly, and maintain the sealing state of the sealing rings 72 and sealing gaskets 93.

[0036] like Figure 5 As shown, the cavity 8 is further described. The lower inner wall of the cavity 8 has a mounting groove 82, and the sealing gasket 93 is installed in the mounting groove 82.

[0037] Specifically, the sealing gasket 93 is installed in the mounting groove 82, which increases the contact area of ​​the sealing gasket 93 and also prevents the sealing gasket 93 from shifting, thus limiting the sealing gasket 93 and ensuring that it is in a sealed state.

[0038] like Figure 5 As shown, the cavity 8 is further described. The lower end of the cavity 8 has an integrally formed support layer 81. There are multiple support layers 81, which are distributed around the axis of the cavity 8. The support layer 81 is "L" shaped. The lower end of the motor 7 protrudes outward and passes through the inner sleeve layer 9 and is sandwiched between the multiple support layers 81. The protruding part of the lower end of the motor 7 abuts against the support layer 81. There is a water inlet gap between the lower end of the motor 7 and the lower extension edge 92 of the inner sleeve layer 9.

[0039] Specifically, during installation, the lower protruding part of the motor 7 is clamped and abutted by multiple support layers 81 to fix the motor 7. Water can move from around the motor 7 into the cavity 8 through the gap between the multiple support layers 81. However, water moves between the inner sleeve layer 9 and the sealing ring 72 and sealing gasket 93 of the inner sleeve layer 9 and the extended edge 92 of the inner sleeve layer 9.

[0040] The housing of motor 7 is sealed and waterproof. It should be noted that waterproofing of motor 7 is already existing technology.

[0041] like Figure 6 Further explanation of the threaded layer 94 is shown below. The threaded layer 94 is also made of metal and is integrally set on the inner wall of the inner sleeve layer 9. The threaded layer 94 spirals upward, so that the water passing outside the motor 7 moves in a spiral motion.

[0042] Specifically, the threaded layer 94 is disposed between the motor 7 and the inner sleeve layer 9, so that the water moves spirally along the threaded layer 94.

[0043] The inner sleeve layer 9 and the threaded layer 94 are made of aluminum. It should be noted that aluminum is not prone to rust when submerged in water for a long time and can maintain its integrity over a long period of time.

[0044] like Figures 6-7 As shown, the inner side of the threaded layer 94 has a sealing gasket 2 96, which is spirally rising along the threaded layer 94 and is pressed against the outer wall of the motor 7.

[0045] Specifically, sealing gasket 2 96 is used to seal the inward side of threaded layer 94, so that water can only move along the threads of threaded layer 94 during movement, avoiding the formation of stagnant areas.

[0046] like Figure 7 As shown, the inner side of the threaded layer 94 has an integral frame edge 95, which spirals upward along the threaded layer 94. The sealing gasket 2 96 is clamped inside the frame edge 95 and is pressed against the inner wall of the frame edge 95.

[0047] Specifically, the second sealing gasket 96 is confined within the frame edge 95, thus confining the second sealing gasket 96 and ensuring that it is fully clamped between the frame edge 95 and the motor 7, achieving a stable sealing effect.

[0048] like Figure 7 Further explanation of the frame edge 95 is provided. The frame edge 95 is made of aluminum and has a C-shaped cross-section, which is used to limit the sealing gasket 2 96.

[0049] Specifically, the shape of the frame edge 95C ensures that the sealing gasket 2 96 is limited. During the installation of the inner sleeve layer 9, it needs to be sleeved with the motor 7 so that the sealing gasket 2 96 can slide along the outer shell of the motor 7 to prevent the sealing gasket 2 96 from falling off the frame edge 95.

[0050] Working principle: The lithium battery 2 powers the motor 7, which drives the plunger pump 6 to work. The plunger pump 6 is used to drive the movement of water. It should be noted that this is existing technology. In addition, the movement of water entering the cavity 8 and passing through the motor 7 is also existing technology and will not cause water to enter the motor 7.

[0051] The plunger pump 6 drives water to enter from the inlet pipe 4, pass through the cavity 8 and the flow channel 5, and move out from the outlet pipe 3. When the water passes through the cavity 8, due to the inner sleeve layer 9, the water enters from the lower end of the motor 7 between the motor 7 and the inner sleeve layer 9, and moves along the threaded layer 94, causing the water to spiral up along the outer wall of the motor 7 and move from the outlet 91 into the flow channel 5. This allows the water to be in contact with the outer shell of the motor 7 for a long time and there is no stagnant area, which fully removes the heat generated by the motor 7 and avoids local temperature rise.

[0052] It should be noted that the inner sleeve 9 is fitted inside the cavity 8, and its upper and lower ends have extended edges 92. These edges are sealed by the sealing ring 72 and the first sealing gasket 93, so that water can only move from inside the inner sleeve 9 and out of the outlet 91. It should also be noted that as water moves along the threaded layer 94, it can easily create water grooves on the inner wall of the threaded layer 94 and the inner sleeve 9, reducing the water flow channel and affecting the water output. The inner sleeve 9 is easy to separate from the cavity 8 and the motor 7, making it easy to replace. In addition, the sealing ring 72, the first sealing gasket 93, and the second sealing gasket 96 are all easy to replace.

[0053] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the utility model product is usually placed in during use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand this utility model and its core ideas.
