Detailed Description

Other aspects, features and advantages of the present invention will become apparent from the following detailed description, taken in conjunction with the accompanying drawings, which form a part of this specification, and which illustrate, by way of example, the principles of the invention. In the referenced drawings, the same or similar components in different drawings are denoted by the same reference numerals.

The invention provides a plunger type non-electric self-priming shower, as shown in figures 1-13, comprising a housing with a hole for mounting a deformable plunger pump and a power wheel 9, and a chamber for mixing cold water and hot water inside. The cold water inlet pipe 5 is connected with the cabin where the plunger is positioned through the fixing nut 4, so that water can be ensured to be injected into the plunger cabin; the other side of the cold water inlet pipe 5 is connected with a water tap; the cold water outlet pipe 6 is connected with the warm water cabin 7; the chamber where the piston 2 is located is a heat absorption water chamber, hot water is absorbed by the piston 2, and meanwhile, the one-way valve 1 is used for ensuring that the hot water cannot be discharged or absorbed to the wrong chamber; a heat absorption water pipe is additionally arranged below the heat absorption water cabin, and the right side of the heat absorption water cabin is connected with the warm water cabin 7 through a one-way valve; a warm water outlet pipe is additionally arranged below the warm water cabin 7; the warm water outlet pipe is connected with the shower nozzle; the piston connecting rod 3 is connected with two power wheels 9, so that the rotary motion of the power wheels 9 can be converted into reciprocating piston motion; the power wheel 9 is connected with the plunger sleeve 11 and provides power through the rotation of the plunger sleeve 11; a plurality of plungers are arranged in the plunger sleeve 11, and the effect of driving the whole plunger sleeve 11 to rotate can be achieved by applying the principle of a plunger motor; the power wheel 9 and the heat absorption water tank are two, the working frequencies of the two pistons 2 are different, and when the left piston is positioned at the bottom dead center, the right piston is positioned at the top dead center, so that the discharged warm water can be uninterrupted; the front end of the plunger is provided with small wheels 10 which can freely rotate around the central line of the plunger, and the two small wheels 10 are a pair and ride on the raised edges in the shell; grooves for the ridges and the small wheels to be clamped in can guide the small wheels; the tolerance between the plunger and the plunger sleeve 11 and the tolerance between the plunger sleeve 11 and the shell ensure that water can permeate into the shell for lubrication on the premise of finishing normal work; the left side of the plunger sleeve fixer 13 is propped against the shell, the right side of the plunger sleeve fixer is propped against the plunger sleeve 11, and the diameter of the plunger sleeve fixer does not interfere with the work of the plunger so as to position the plunger sleeve 11; the valve 12 is opened only when the water pressure reaches a certain degree, and the specific working principle is shown in figure 13; each opening which needs to be connected with the pipeline is provided with threads.

The heat absorption water device of the invention is provided with a chamber where a piston 2 is positioned as a heat absorption water chamber, a water pipe for hot water is connected with a one-way valve 1 which is opened inwards, and a hot water outlet hole is provided with the one-way valve 1 which is opened outwards, thereby avoiding absorbing or discharging wrong hot water. Hot water is sucked by the piston 2 while being discharged or absorbed to the hot water absorption chamber through the check valve 1. The cold water inlet pipe and the cold water outlet pipe and the hot water outlet pipe of the invention are converged into a hot water outlet pipe 8, and the cold water inlet pipe and the hot water inlet pipe are respectively provided with a control valve for respectively controlling water temperature and water outlet amount.

In order to facilitate the installation of the plunger sleeve and the power wheel in the shell, the shell is designed into a left part and a right part in the molding stage, the plunger sleeve 11 and the power wheel 9 are placed in the shell which is not combined after the installation is finished, and then the shell is combined into a whole to finish the installation.

During specific work, tap water enters the cabin where the plunger is located through the cold water inlet pipe 5, the cabin formed by the plunger and the plunger sleeve 11 is expanded by cold water, the plunger can drive the plunger sleeve 11 to rotate due to the small wheel 10 and the arc line on the shell, and when the plunger starts to ascend a slope again, the water inside the plunger can be extruded out and enters the warm water bin. The rotating power is transmitted to the power wheel 9, and can be converted into vertical reciprocating motion through the piston connecting rod 3 and the piston 2, due to the two one-way valves 1 below, warm water in the warm water cabin can not be sucked in the hot water cabin, hot water can not be pressed into the heat absorption water pipe, all the hot water can enter the warm water cabin 7 to be mixed with cold water to form warm water, and the warm water enters the shower nozzle through the warm water outlet pipe 8, so that bathing is completed.

During operation, the power wheel 9 is connected with the plunger sleeve 11 through a bolt, and meanwhile, the outer side of the small fan-shaped edge at the joint of the power wheel 9 can tightly push the inner side of the large fan-shaped edge in the plunger sleeve 11, so that excessive material fatigue cannot be generated. When the water temperature is adjusted, the screw can be extruded into the hot water pipe by adjusting the control valve structure on the hot water pipe, so that the water temperature is reduced. The water outlet size of the water faucet can be adjusted to achieve the same purpose. When the water yield of the spray head is adjusted, the screw can extrude the warm water pipe by adjusting the control valve structure on the warm water pipe, and the water yield is further reduced. The water outlet size of the water faucet can be adjusted to achieve the same purpose.

Compared with the 'bathing magic device' on the market, the shower head has more stable water outlet temperature, and the condition that the water temperature is reduced when the shower head is lifted can not occur due to the use of the hydraulic mechanism, so that the shower head works more reliably.

While the foregoing is directed to the preferred embodiment of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
